Entry Into a Material Definitive Agreement.

Underwriting Agreement

On April 30, 2015, Black Stone Minerals, L.P. (the “Partnership”) entered into an Underwriting Agreement (the “Underwriting Agreement”), by and among the Partnership, Black Stone Minerals GP, L.L.C. (the “General Partner”), Black Stone Minerals Company, L.P. (“BSMC”), BSMC GP, L.L.C. (“BSMC GP”), and Black Stone Natural Resources, L.L.C. (“BSNR,” together with the Partnership, the General Partner, and BSMC, the “Partnership Parties”) and Barclays Capital Inc., Citigroup Global Markets Inc., and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several underwriters named therein (the “Underwriters”), providing for the offer and sale by the Partnership (the “Offering”), and purchase by the Underwriters, of 22,500,000 common units representing limited partner interests in the Partnership at a price to the public of $19.00 per common unit. Pursuant to the Underwriting Agreement, the Partnership also granted the Underwriters an option for a period of 30 days to purchase up to an additional 3,375,000 common units to cover over-allotments, if any, on the same terms.

The material terms of the Offering are described in the prospectus, dated April 30, 2015 (the “Prospectus”), filed by the Partnership with the United States Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”). The Offering is registered with the Commission pursuant to a Registration Statement on Form S-1, as amended (File No. 333-202875).

The Underwriting Agreement contains customary representations, warranties, and agreements of the Partnership Parties, and customary conditions to closing, obligations of the parties, and termination provisions. The Partnership Parties have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act.

The Offering closed on May 6, 2015. At closing, the Partnership received proceeds from the Offering (after deducting the underwriting discount, structuring fee, and estimated offering expenses) of approximately $400.7 million. The Partnership will use the net proceeds to repay indebtedness outstanding under its credit facility.

As more fully described under the caption “Underwriting” in the Prospectus, the Underwriters and their respective affiliates are full-service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage, and other financial and non-financial activities and services. The Underwriters and their affiliates have in the past, and may in the future, perform investment banking, commercial banking, advisory, and other services for the Partnership and its respective affiliates from time to time for which they have received, and may in the future receive, customary fees and expenses. Affiliates of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wells Fargo Securities, LLC, J.P. Morgan Securities LLC, and Scotia Capital (USA) Inc. are lenders under the Partnership’s revolving credit facility and, accordingly, will receive a portion of the net proceeds from the Offering.

Long-Term Incentive Plan

In connection with the Offering, the Board of Directors (the “Board”) of the General Partner adopted a Long Term Incentive Plan (the “LTIP”) for non-employee directors of the General Partner and certain employees and consultants of the General Partner and the Partnership’s affiliates. The LTIP provides for the grant, from time to time, at the discretion of the Board or a committee thereof, of unit options, unit appreciation rights, restricted units, phantom units, unit awards, distribution equivalent rights, cash awards, and other unit-based awards. Subject to adjustment in the event of certain transactions or changes in capitalization, an aggregate of 15,148,096 units may be delivered pursuant to awards under the LTIP. Units subject to awards that are forfeited, cancelled, exercised, paid, or otherwise terminated without the delivery of units, and units held back to cover the exercise price or tax withholding applicable to an award, are available for delivery pursuant to other awards under the LTIP. Under the LTIP, the maximum aggregate grant date fair value of awards granted to a non-employee director of the General Partner during any calendar year will not exceed $500,000 (or $600,000 in the first year in which an individual becomes a non-employee director). The LTIP will be administered by the Board of the General Partner or a committee thereof.

Ladies and Gentlemen:

Black Stone Minerals, L.P., a Delaware limited partnership (the “Partnership”), proposes to sell 22,500,000 common units (the “Firm Units”) representing limited partner interests in the Partnership (the “Common Units”) to the underwriters (the “Underwriters”) named in Schedule I attached to this agreement (this “Agreement”). In addition, the Partnership proposes to grant to the Underwriters an option to purchase up to 3,375,000 additional Common Units on the terms set forth in Section 2 (the “Option Units”). The Firm Units and the Option Units, if purchased, are hereinafter collectively called the “Units.” This Agreement is to confirm the agreement concerning the purchase of the Units from the Partnership by the Underwriters.

It is understood and agreed to by all parties hereto that prior to the date hereof the following transactions (the “Prior Transactions”) occurred:

1. Black Stone Minerals Company, L.P., a Delaware limited partnership (“BSMC”), and its wholly owned subsidiary, Black Stone Natural Resources, L.L.C., a Delaware limited liability company (“BSNR”), formed the Partnership (i) to which BSMC contributed a nominal amount of capital in exchange for all of the limited partner interests in the Partnership and (ii) in which BSNR received a non-economic general partner interest.

2. The Partnership then formed Black Stone Minerals Merger Sub LLC, a Delaware limited liability company (“Merger Sub”), to which it contributed a nominal amount of capital in exchange for all of the membership interests in Merger Sub.

3. The Partnership formed Black Stone Minerals GP, L.L.C., a Delaware limited liability company and new wholly owned subsidiary of the Partnership (the “General Partner”), to function as the general partner of the Partnership. BSNR assigned its general partner interest in the Partnership to the General Partner.

It is further understood and agreed to by the parties hereto that the following additional transactions (the “Closing Transactions”) will occur at or prior to the closing of the offering of the Firm Units on the Initial Delivery Date (as hereinafter defined):

1. The Sixth Amended and Restated Agreement of Limited Partnership of BSMC (as amended, the “Sixth A/R BSMC LP Agreement”) will be amended to allow BSNR to hold units in BSMC.

2. BSMC will contribute cash to BSNR in an amount sufficient to allow BSNR to acquire Class A common units of BSMC representing a 1% limited partner interest in BSMC. BSMC will contribute cash to the Partnership, and the Partnership will contribute cash to the General Partner, in an amount sufficient to allow the General Partner to acquire a 1% limited partner interest in the Partnership.

3. BSNR will contribute to BSMC the cash previously contributed to it by BSMC in exchange for Class A common units representing a 1% limited partner interest in BSMC. In connection with this contribution, (i) a Unit Subscription Agreement by and between BSNR and BSMC (including BSNR’s agreement to be bound by the Sixth A/R BSMC LP Agreement, as a limited partner of BSMC) will be entered into (the “Unit Subscription Agreement”) and (ii) Schedule 1 of the Sixth A/R BSMC LP Agreement will be amended reflecting the issuance of Class A common units to BSNR.

4. The General Partner will contribute to the Partnership the cash previously contributed to it by BSMC and by the Partnership to the General Partner in exchange for a 1% limited partner interest in the Partnership. In connection with this contribution, (i) the General Partner and the Partnership will enter into a subscription agreement (the “Subscription Agreement”) and (ii) BSMC and the General Partner will amend the Agreement of Limited Partnership of the Partnership (as amended, the “Amended Initial MLP LP Agreement”).

5. Immediately prior to the merger discussed below, the Amended Initial MLP LP Agreement will be amended and restated into the First Amended and Restated Agreement of Limited Partnership of the Partnership (the “Partnership Agreement”), and the initial limited partner interest of BSMC in the Partnership will be converted into Common Units and the limited partner interest of the General Partner will be converted into Common Units and subordinated units of the Partnership (the “Subordinated Units”).

6. BSMC, Merger Sub and the Partnership will enter into a merger agreement (the “Merger Agreement”) under which BSMC will merge with and into Merger Sub with BSMC surviving. In connection with the merger:

(a) the Common Units held by BSMC will be redeemed in exchange for a return of its original capital contribution;

(b) the BSMC Class A common units and Class B common units (other than Class A common units held by BSNR) will be exchanged for Common Units and the

Subordinated Units and the preferred units representing limited partner interests in BSMC will be exchanged for preferred units representing limited partner interests in the Partnership (the “Preferred Units”);

(c) the BSMC Class A common units held by BSNR will remain outstanding as limited partner interests, and the General Partner will retain its non-economic general partner interest in the Partnership and its Common Units;

(d) the Partnership’s equity interest in Merger Sub will be converted into a limited partner interest in BSMC; and

(e) BSNR will retain its non-economic general partner interest in BSMC.

(f) Immediately following the merger, the Partnership and BSNR will enter into the Seventh Amended and Restated Limited Partnership Agreement of BSMC (the “Seventh A/R BSMC LP Agreement”).

7. The Partnership will form BSMC GP, L.L.C., a new wholly owned Delaware limited liability company (“BSMC GP”) to function as general partner of BSMC and enter into the Limited Liability Company Agreement of BSMC GP (the “BSMC GP LLC Agreement”). The Partnership will remove BSNR as general partner of BSMC and appoint BSMC GP as general partner of BSMC. Following such removal and appointment, BSNR and BSMC GP will enter into an Assignment of Partnership Interest (assigning the general partner interest in BSMC and amending the Seventh A/R BSMC LP Agreement reflecting the same) (the “BSMC Assignment of Partnership Interest”). The Limited Liability Company Agreement of the General Partner will be amended and restated into the form desired at the time of the offering of the Units (the “A/R GP LLC Agreement”).

8. The public, through the underwriters, will contribute to the Partnership cash in exchange for Common Units.

9. The Partnership will use the net proceeds of the offering of the Units as provided in the “Use of Proceeds” section of the Registration Statement (as defined below). In connection therewith, the Partnership will contribute a portion of the net proceeds of the offering to BSMC in exchange for an additional limited partner interest in BSMC, and the Seventh A/R BSMC LP Agreement will be amended to reflect the new limited partner interest.

The Prior Transactions and the Closing Transactions are collectively referred to herein as the “Transactions.” As used herein, (i) “Transaction Agreements” means, collectively, the Unit Subscription Agreement, the Subscription Agreement, the Merger Agreement and the BSMC Assignment of Partnership Interest, (ii) the Third Amended Restated Credit Agreement, among BSMC, as Borrower, Wells Fargo Bank, National Association, as Administrative Agent, Bank of America, N.A. and Compass Bank, as Co-Syndicate Agents, Wells Fargo Bank, N.A. and Amegy Bank National Association, as Co-Documentation Agents, and a syndicate of lenders dated as of January 23, 2015 (such agreement, together with any amendments and/or restatements thereof on or prior to the applicable Delivery Date, the “Credit Agreement”), and (iii) the “Organizational Agreements” means, collectively, the Partnership Agreement, the A/R GP LLC Agreement, the Seventh A/R BSMC LP Agreement, as amended, the BSMC GP LLC

The Organizational Agreements, the Credit Agreement and the Transaction Agreements are collectively called the “Operative Agreements.”

8. Indemnification and Contribution.

(a) The Partnership Parties hereby agree, jointly and severally, to indemnify and hold harmless each Underwriter, its affiliates, directors, officers and employees and the agents of each Underwriter who have or who are alleged to have participated in the distribution of the Units as underwriters (collectively, “selling agents”) and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Units), to which that Underwriter, affiliate, director, officer, employee, selling agent or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by any Underwriter, (D) any materials or information provided to investors by, or with the approval of, the Partnership in connection with the marketing of the offering of the Units, including any “road show” (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus and any Written Testing-the-Waters Communication (“Marketing Materials”), or (E) any Blue Sky application or other document prepared or executed by the Partnership Parties (or based upon any written information furnished by the Partnership Parties for use therein) specifically for the purpose of qualifying any or all of the Units under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, and shall reimburse each Underwriter and each such affiliate, director, officer, employee, selling agent or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, affiliate, director, officer, employee, selling agent or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that none of the Partnership Parties shall be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment

or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Partnership through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability which any Partnership Party may otherwise have to any Underwriter or to any affiliate, director, officer, employee, selling agent or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless each Partnership Party, its directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the General Partner), officers, employees and each person, if any, who controls such Partnership Party within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which such Partnership Party, or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they are made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Partnership through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the any Partnership Party or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be

entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees, selling agents and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees, selling agents and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party (it being understood, however, that the indemnifying party shall not be liable for the expense of more than one separate counsel for the indemnified parties and their respective directors, officers, employees, selling agents and controlling persons (in addition to any local counsel) in any one action, suit or proceeding or series of related actions, suits or proceedings in the same jurisdiction representing the indemnified parties who are parties to such action, suit or proceeding); or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees, selling agents or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(a) hereof, the indemnifying party agrees that it shall be liable for any settlement of any

proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, from the offering of the Units, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Partnership Parties, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Common Units purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Units exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from

any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Partnership Parties acknowledge and agree that the statements regarding delivery of Units by the Underwriters set forth on the cover page of, the statements in the second paragraph following the table under the caption “Underwriting — Commissions and Expenses,” the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting — Stabilization, Short Positions and Penalty Bids” and the paragraph relating to discretionary sales appearing under the caption “Underwriting — Discretionary Sales” in the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials.

9. Defaulting Underwriters.

(a) If, on any Delivery Date, any Underwriter defaults in its obligations to purchase the Units that it has agreed to purchase under this Agreement, the remaining non-defaulting Underwriters may in their discretion arrange for the purchase of such Units by the non-defaulting Underwriters or other persons satisfactory to the Partnership on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Units, then the Partnership shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Units on such terms. In the event that within the respective prescribed periods, the non-defaulting Underwriters notify the Partnership that they have so arranged for the purchase of such Units, or the Partnership notifies the non-defaulting Underwriters that it has so arranged for the purchase of such Units, either the non-defaulting Underwriters or the Partnership may postpone such Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement, and the Partnership agrees to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or in any such other document or arrangement that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 9, purchases Units that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Partnership as provided in paragraph (a) above, the total number of Units that remains unpurchased does not exceed one-eleventh of the total number of Units, then the

Partnership shall have the right to require each non-defaulting Underwriter to purchase the total number of Units that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the total number of Units that such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; provided that the non-defaulting Underwriters shall not be obligated to purchase more than 110% of the total number of Units that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2.

(c) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Partnership as provided in paragraph (a) above, the total number of Units that remains unpurchased exceeds one-eleventh of the total number of all of the Units, or if the Partnership shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Partnership, except that the Partnership will continue to be liable for the payment of expenses as set forth in Sections 6 and 11 and except that the provisions of Section 8 shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership or any non-defaulting Underwriter for damages caused by its default.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Partnership prior to delivery of and payment for the Firm Units if, prior to that time, any of the events described in Sections 7(k), 7(l) and 7(m) shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.

11. Reimbursement of Underwriters’ Expenses. If (a) the Partnership shall fail to tender the Units for delivery to the Underwriters for any reason, or (b) the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement, the Partnership will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriters) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Units, and upon demand the Partnership shall pay the full amount thereof to the Representatives. Notwithstanding the foregoing, if this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters or the purchase of the Units is not consummated as a result of the occurrence of any of the events described in Section 7(m) (other than the occurrence of an event described in Section 7(m)(i)(B)), the Partnership shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

12. Research Analyst Independence. The Partnership Parties acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make

statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of their respective investment banking divisions. The Partnership Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Partnership Parties may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Partnership Parties by such Underwriters’ investment banking divisions. The Partnership Parties acknowledge that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

13. No Fiduciary Duty. Each of the Partnership Parties acknowledges and agrees that in connection with this offering, the sale of the Units or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (a) no fiduciary or agency relationship between any of the Partnership Parties and any other person, on the one hand, and the Underwriters, on the other, exists; (b) the Underwriters are not acting as advisors, expert or otherwise, to any of the Partnership Parties, including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the Partnership Parties, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriters may have to the Partnership Parties shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriters and their respective affiliates may have interests that differ from those of the Partnership Parties. Each of the Partnership Parties hereby waives any claims that any of the Partnership Parties may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

14. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

16. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Partnership Parties and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Units and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

As Representatives of the several

Underwriters named in Schedule I,

c/o Barclays Capital Inc.

745 Seventh Avenue

New York, New York 10019

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of common units (the “Units”) representing limited partner interests (“Common Units”) of Black Stone Minerals, L.P., a Delaware limited partnership (the “Partnership”), and that the Underwriters propose to reoffer the Units to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Units (including, without limitation, Common Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Units that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Units, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Common Units or securities convertible into or exercisable or exchangeable for Common Units or any other securities of the Partnership, or (4) publicly disclose the intention to do any of the foregoing for a period commencing on the date hereof and ending on the 180th day after the date of the Prospectus relating to the Offering (such 180-day period, the “Lock-Up Period”).

Exhibit A-1

The foregoing paragraph shall not apply to (a) bona fide gifts, sales or other dispositions of Common Units, in each case that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited liability company); provided that it shall be a condition to any transfer pursuant to this paragraph that (i) the transferee/donee agrees to be bound by the terms of this Lock-Up Letter Agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee/donee were a party hereto, (ii) each party (donor, donee, transferor or transferee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the Securities Exchange Act of 1934, as amended) to make, and shall agree to not voluntarily make, any filing or public announcement of the transfer or disposition prior to the expiration of the 180-day period referred to above, and (iii) the undersigned notifies Barclays Capital Inc. at least two business days prior to the proposed transfer or disposition, (b) the exercise of warrants or the exercise of options granted pursuant to the Partnership’s option/incentive plans or otherwise outstanding on the date hereof; provided, that the restrictions shall apply to Common Units issued upon such exercise or conversion and (c) the establishment of any contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, however, that no sales of Common Units or securities convertible into, or exchangeable or exercisable for, Common Units, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the Lock-Up Period (as the same may be extended pursuant to the provisions hereof); provided further, that the Partnership is not required to report the establishment of such Rule 10b5-1 Plan in any public report or filing with the Commission under the Exchange Act during the lock-up period and does not otherwise voluntarily effect any such public filing or report regarding such Rule 10b5-1 Plan.

In furtherance of the foregoing, the Partnership and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Partnership notifies the Underwriters that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Units, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Partnership and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership and the Underwriters.

[Signature page follows]

Exhibit A-2

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

1. Each of the entities listed in Exhibit A to this opinion (the “Operating Subsidiaries”) has been duly formed and is validly existing as a [limited liability company or limited partnership] as indicated in such exhibit and is in good standing under the laws of the State of Delaware or Texas, as applicable.

2. Each of the Operating Subsidiaries has all partnership or limited liability company power and authority, as the case may be, necessary to (A) own, lease and operate its properties and to conduct its business as described in the Registration Statement, Disclosure Package and Prospectus and (B) enter into and perform its obligations under each Operative Agreement to which it is a party.

3. BSMC owns a 100% limited liability company interest in BSNR; such limited liability company interest has been duly authorized and is validly issued in accordance with the Sixth A/R BSNR LLC Agreement, fully paid (to the extent required under the Sixth A/R BSNR LLC Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 18-607 and 18-804 of the Delaware LLC Act); and BSMC owns such limited liability company interest free and clear of all Liens in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming BSMC as debtor is on file in the office of the Secretary of State of the State of Delaware, other than Liens in favor of the lenders under the Credit Agreement.

4. [BSMC owns, directly or indirectly 100% of the membership, partnership or other ownership interests in each of the Operating Subsidiaries; each such membership, partnership or other ownership interest has been duly authorized and validly issued in accordance with the limited liability company agreement, partnership agreement or other organizational documents of such Operating Subsidiary, and in accordance with the laws of the jurisdiction of organization of such Operating Subsidiary, is fully paid (to the extent required under the limited liability company agreement, partnership agreement or other organizational documents of such Operating Subsidiary) and nonassessable (except as such nonassessability may be affected by matters described in [Sections 18-607 and 18-804 of the Delaware LLC Act] [or other similar statutory provisions of the laws of the jurisdiction of organization of such Operating Subsidiary]); and the owner of such membership, partnership or other ownership interest owns such interest free and clear of all Liens in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming [the Partnership or any of its subsidiaries][BSMC] as debtor is on file in the office of the Secretary of State of the State of Delaware, other than Liens in favor of the lenders under the Credit Agreement.

5. The offer and issuance by the Partnership of all the limited partner interests in the Partnership that shall be issued and outstanding on the date hereof after consummation of the sale of Units to the Underwriters pursuant to the Underwriting Agreement (other than the offer and issuance of the limited partner interests represented by such Units issued and sold to the Underwriters) do not require registration under the Securities Act.

Exhibit B-1

6. The statements in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the captions “Summary—The Offering,” “Cash Distribution Policy and Restrictions on Distributions,” “Description of Our Common Units,” “Description of Our Preferred Units” and “The Partnership Agreement,” insofar as they purport to constitute a summary of the terms of the Common Units, the Subordinated Units or the Preferred Units, are accurate summaries in all material respects.

7. The statements in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the captions “Cash Distribution Policy and Restrictions on Distributions,” “Business—Environmental Matters,” “Management—Certain Relationships and Related Transactions,” “Fiduciary Duties,” “The Partnership Agreement,” “Material U.S. Federal Income Tax Consequences” and “Investment in Black Stone Minerals, L.P. by Employee Benefit Plans,” in each case, insofar as they purport to constitute summaries of provisions of New York or federal statutes, rules or regulations or the Delaware LP Act or Delaware LLC Act or of contracts, constitute accurate summaries thereof in all material respects.

8. Except as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus and except pursuant to the Credit Agreement, there are no options, warrants, preemptive rights, rights of first refusal or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any equity securities of any of the Partnership Entities, in each case pursuant to the Organizational Agreement of the Partnership Entities or any other agreement filed as an exhibit to the Registration Statement. To our knowledge, neither the filing of the Registration Statement nor the offering or sale of the Units as contemplated by the Underwriting Agreement gives rise to any rights for or relating to the registration of any Common Units or other securities of the Partnership.

9. The Underwriting Agreement has been duly authorized, executed and delivered by each of the Partnership Parties.

10. None of (i) the offering, issuance or sale of the Units and the application of the proceeds from the sale of the Units as described under “Use of Proceeds” in the Prospectus, (ii) the execution, delivery and performance of the Underwriting Agreement or the Operative Agreements by the Partnership Entities party thereto or (iii) the consummation of the Transactions or any other transactions contemplated by the Underwriting Agreement or the Transaction Agreements (A) constitutes or will constitute a breach or violation of, or a default under, any of the Organizational Documents of any of the Operating Subsidiaries, (B) constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) or results or will result in the creation or imposition of any Lien (other than Lien arising under or in connection with the Credit Agreement) upon any property or assets of any of the Partnership Entities, under any agreement filed as an exhibit to the Registration Statement (other than the Partnership Agreement) or (C) results or will result in any violation of the applicable laws of the State of Texas, the State of New York or the federal laws of the United States of America (it being understood that we do not express an opinion in clause (C) of this paragraph 10. with respect to any securities or other

Exhibit B-2

anti-fraud law), except in the case of clauses (B) and (C) for such breaches, violations, Liens as would not reasonably be expected to have a Material Adverse Effect or materially impair the ability of any of the Partnership Entities to consummate the Closing Transactions or any other transactions provided for in the Underwriting Agreement or the Operative Agreements.

11. No consent of or with any U.S. federal, Texas, New York court or governmental agency or body having jurisdiction over any of the Partnership Entities or any of their properties or assets is required in connection with (i) the offering, issuance or sale by the Partnership of the Units and the application of the proceeds from the sale of the Units as described under “Use of Proceeds” in the Prospectus, (ii) the execution, delivery and performance of the Underwriting Agreement and the Operative Agreements by the Partnership Entities party thereto or (iii) the consummation of the Transactions or any other transactions contemplated by the Underwriting Agreement or the Operative Agreements, except (A) such as may be required under the Securities Act, the Exchange Act, applicable state securities or “Blue Sky” laws, the rules of the NYSE and the rules of the FINRA (in each case as to which we express no opinion), (B) such as have been obtained or made and (C) such that the failure to obtain would not reasonably be expected to have a Material Adverse Effect or materially impair the ability of any of the Partnership Entities to consummate the Closing Transactions or any other transactions provided for in the Underwriting Agreement or the Operative Agreements.

12. The Registration Statement has been declared effective under the Securities Act; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus in accordance with Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such rule.

13. The Registration Statement, on the Effective Date, the Pricing Disclosure Package, at the Applicable Time and the Prospectus, as of its date (in each case other than the financial statements, schedules or other financial data and oil and natural gas reserve data and reports, in each case included in or omitted from the Registration Statement, Pricing Disclosure Package or the Prospectus, as to which we express no opinion), each appeared on its face to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-1 under the Securities Act and the rules and regulations of the Commission thereunder (other than with respect to Regulation S-T).

14. None of the Partnership Entities is, and after giving effect to the sale of the Units and the application of the proceeds as described in the Prospectus, under the caption “Use of Proceeds,” will be, an “investment company” within the meaning of the Investment Company Act.

15. To our knowledge, there is no franchise, contract or other document of a character required to be described in the Registration Statement or Prospectus, or to be filed as an exhibit thereto, which is not described or filed as required by the Securities Act or the rules and regulations thereunder.

(a)

the Registration Statement, at the time it became effective on the Effective Date (including the information deemed to be a part of the Registration Statement pursuant to Rule 430A under the Securities Act), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading;

(b)

the Pricing Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(c)

the Prospectus, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading,

it being understood that in each case we do not express any belief with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the independent public accounting firm’s report thereon, (ii) any other financial and accounting data or (iii) any oil and natural gas reserve data or reports, in each case included in or omitted from the Registration Statement, the Pricing Disclosure Package and the Prospectus.

In rendering such opinions, such counsel may (i) rely in respect of matters of fact upon certificates of officers and employees of the Partnership Entities and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (iii) state that such counsel’s opinions are limited to federal laws of the United States of America, the laws of the States of New York and Texas, the Delaware LP Act and the Delaware LLC Act and (iv) state that such counsel expresses no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local tax statutes to which any of the Partnership Parties may be subject.

ARTICLE I

DEFINITIONS

Section 1.1 Definitions. The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary, applied to the terms used in this Agreement.

“Adjusted Capital Account” means, with respect to any Partner, the balance in such Partner’s Capital Account at the end of each taxable period of the Partnership, after giving effect to the following adjustments:

(b) Debit to such Capital Account the items described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) and 1.704-1(b)(2)(ii)(d)(6).

The foregoing definition of Adjusted Capital Account is intended to comply with the provisions of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. The “Adjusted Capital Account” of a Partner in respect of any Partnership Interest shall be the amount that such Adjusted Capital Account would be if such Partnership Interest were the only interest in the Partnership held by such Partner from and after the date on which such Partnership Interest was first issued.

“Adjusted Operating Surplus” means, with respect to any period, (a) Operating Surplus generated with respect to such period; (b) less (i) the amount of any net increase during such period in Working Capital Borrowings (or the Partnership’s proportionate share of any net increase in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned); and (ii) the amount of any net decrease during such period in cash reserves (or the Partnership’s proportionate share of any net decrease in cash reserves in the case of Subsidiaries that are not wholly owned) for Operating Expenditures not constituting Operating Expenditures made during such period; and (c) plus (i) the amount of any net decrease during such period in Working Capital Borrowings (or the Partnership’s proportionate share of any net decrease in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned); (ii) the amount of any net increase during such period in cash reserves (or the Partnership’s proportionate share of any net increase in cash reserves in the case of Subsidiaries that are not wholly owned) for any Operating Expenditures required by any debt instrument for the repayment of principal, interest or premium; and (iii) the amount of any net decrease made in subsequent periods in cash reserves for any Operating Expenditures initially established during such period to the extent such decrease results in a reduction in Adjusted Operating Surplus in subsequent periods pursuant to clause (b)(ii) above. Adjusted Operating Surplus does not include that portion of Operating Surplus included in clause (a)(i) of the definition of Operating Surplus. To the extent that disbursements made, cash received or cash reserves established, increased or reduced, or Working Capital Borrowings increased or reduced, after the end of a period are included in the determination of Operating Surplus for such period (as contemplated by the proviso in the definition of “Operating Surplus”) such disbursements, cash receipts and changes in cash reserves or Working

Capital Borrowings shall be deemed to have occurred in such period (and not in any future period) for purposes of calculating increases or decreases in Working Capital Borrowings or cash reserves during such period.

“Bad Faith” means, with respect to any determination, action or omission, of any Person, board or committee, that such Person, board or committee reached such determination, or engaged in or failed to engage in such act or omission, with the belief that such determination, act or omission was adverse to the interests of the Partnership.

Notwithstanding anything to the contrary herein, unless the General Partner shall determine otherwise in respect of some or all of any or all classes of Partnership Interests or Derivative Instruments, Partnership Interests and Derivative Instruments shall not be evidenced by Certificates. Certificates that are issued shall be executed on behalf of the Partnership by the Chairman of the Board, President, Chief Executive Officer or any Executive Vice President or Vice President and the Chief Financial Officer or the Secretary or any Assistant Secretary of the General Partner. The signatures of such officers upon a Certificate may, to the extent permitted by law, be facsimiles. In case any officer who has signed or whose signature has been placed upon such Certificate shall have ceased to be such officer before such Certificate is issued, it may be issued by the Partnership with the same effect as if he or she were such officer at the date of its issuance. No Certificate for any class of Partnership Interests or Derivative Instruments shall be valid for any purpose until it has been countersigned by the Transfer Agent for such class of Partnership Interests or Derivative Instruments, provided, however, that, if the General Partner elects to cause the Partnership to issue Partnership Interests or Derivative Instruments of such class in global form, the Certificate shall be valid upon receipt of a certificate from the Transfer Agent certifying that the Partnership Interests or Derivative Instruments, as the case may be, have been duly registered in accordance with the directions of the Partnership. With respect to any Partnership Interests or Derivative Instruments that are represented by physical Certificates, the General Partner may determine that such Partnership Interests or Derivative Instruments, as the case may be, will no longer be represented by physical Certificates and may, upon written notice to the holders of such Partnership Interests or Derivative Instruments, as the case may be, and subject to applicable law, take whatever actions it deems necessary or appropriate to cause such Partnership Interests or Derivative Instruments, as the case may be, to be registered in book entry or global form and may cause such Certificates to be cancelled or deemed cancelled.

Section 4.2 Mutilated, Destroyed, Lost or Stolen Certificates.

(a) If any mutilated Certificate is surrendered to the Transfer Agent, the appropriate officers of the General Partner on behalf of the Partnership shall execute, and the Transfer Agent shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Partnership Interests or Derivative Instruments as the Certificate so surrendered.

(b) The appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and the Transfer Agent shall countersign, a new Certificate in place of any Certificate previously issued if the Record Holder of the Certificate:

(i) makes proof by affidavit, in form and substance satisfactory to the General Partner, that a previously issued Certificate has been lost, destroyed or stolen;

(ii) requests the issuance of a new Certificate before the General Partner has notice that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim;

(iii) if requested by the General Partner, delivers to the General Partner a bond, in form and substance satisfactory to the General Partner, with surety or sureties and with fixed or open penalty as the General Partner may direct, to indemnify the Partnership, the Partners, the General Partner and the Transfer Agent against any claim that may be made on account of the alleged loss, destruction or theft of the Certificate; and

(iv) satisfies any other reasonable requirements imposed by the General Partner or the Transfer Agent.

If a Limited Partner fails to notify the General Partner within a reasonable period of time after such Limited Partner has notice of the loss, destruction or theft of a Certificate, and a transfer of the Partnership Interests or Derivative Instruments represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent receives such notification, the Limited Partner shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate.

(c) As a condition to the issuance of any new Certificate under this Section 4.2, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith.

Section 4.3 Record Holders. The Partnership and the General Partner shall be entitled to recognize the Record Holder as the Partner with respect to any Partnership Interest and, accordingly, shall not be bound to recognize any equitable or other claim to, or interest in, such Partnership Interest on the part of any other Person, regardless of whether the Partnership shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Partnership Interests, as between the Partnership on the one hand, and such other Persons on the other, such representative Person shall be (a) the Record Holder of such Partnership Interest and (b) bound by this Agreement and shall have the rights and obligations of a Partner hereunder as, and to the extent, provided herein.

Section 4.4 Transfer Generally.

(a) The term “transfer,” when used in this Agreement with respect to a Partnership Interest, shall mean a transaction (i) by which the General Partner assigns its General Partner Interest to another Person, and includes a sale, assignment, gift, pledge, grant of security interest, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise, or (ii) by which the holder of a Limited Partner Interest assigns such Limited Partner Interest to another Person who is or becomes a Limited Partner, and includes a sale, assignment, gift, exchange or any other disposition by law or otherwise (but not the pledge, grant of security interest, encumbrance, hypothecation or mortgage), including any transfer upon foreclosure or other exercise of remedies of any pledge, security interest, encumbrance, hypothecation or mortgage.

(b) No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article IV. Any transfer or purported transfer of a Partnership Interest not made in accordance with this Article IV shall be, to the fullest extent permitted by law, null and void.

(c) Nothing contained in this Agreement shall be construed to prevent a disposition by any stockholder, member, partner or other owner of any Partner of any or all of the shares of stock, membership interests, partnership interests or other ownership interests in such Partner and the term “transfer” shall not mean any such disposition.

Section 4.5 Registration and Transfer of Limited Partner Interests.

(a) The General Partner shall keep or cause to be kept on behalf of the Partnership a register in which, subject to such reasonable regulations as it may prescribe, the Partnership will provide for the registration and transfer of Limited Partner Interests in compliance with the terms of this Agreement.

(b) The Partnership shall not recognize any transfer of Limited Partner Interests evidenced by Certificates until the Certificates evidencing such Limited Partner Interests are surrendered for registration of transfer. No charge shall be imposed by the General Partner for such transfer; provided, that as a condition to the issuance of any new Certificate under this Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith. Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions hereof, the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Certificates evidencing Limited Partner Interests, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered. Upon the proper surrender of a Certificate, such transfer shall be recorded in the Partnership register.

(c) Upon the receipt by the General Partner of proper transfer instructions from the Record Holder of uncertificated Partnership Interests, such transfer shall be recorded in the Partnership register.

(d) Except as provided in Section 4.9, by acceptance of any Limited Partner Interests pursuant to a transfer in accordance with this Article IV, each transferee of a Limited Partner Interest (including any nominee, or agent or representative acquiring such Limited Partner Interests for the account of another Person or Group) acknowledges and agrees to the provisions of Section 10.1.

(e) To the fullest extent permitted by law, Initial Limited Partners shall not, for a period of 45 days following the Initial Offering, offer for sale, sell, pledge, transfer, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any Person at any time in the future of) any of the Common Units held by such Person or enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic consequences of ownership of such Common Units, except as permitted by the General Partner.

(f) Except upon the written approval of the General Partner, no Subordinated Unitholder may offer for sale, sell, pledge, transfer, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition to any Person at any time in the future of) any of the Subordinated Units or interest therein, or contract to do or permit any of the foregoing, whether voluntarily or by operation of law, and any attempt to do so shall be void; provided, however, that any Subordinated Unitholder may dispose of all or part of its Subordinated Units to a Permitted Transferee, but only if (i) the Permitted Transferee shall execute a written agreement acknowledging to the Partnership that it is subject to the terms and provisions hereof, including this Section 4.5(f) and (ii) such disposition shall not have as its principal purpose the intent to circumvent the transfer restrictions under this Section 4.5(f). In addition, a Subordinated Unitholder may encumber, mortgage, pledge, grant a security interest or lien in or hypothecate all or part of its Subordinated Units (“Pledged Interest”) in favor of or to any financial institution or other lender (each a “Lender”), but, with respect to any such encumbrance, mortgage, pledge, grant or lien not existing prior to the Effective Time, only if

the Lender shall execute a written agreement acknowledging to the Partnership that should it become a Subordinated Unitholder it is subject to the terms and provisions hereof, including this Section 4.5(f). For this purpose, a “Permitted Transferee” means, with respect to any Subordinated Unitholder, (a) any other Subordinated Unitholder; (b) any Family Member of such Subordinated Unitholder; (c) in the case of a Subordinated Unitholder which is an entity, any owner (including a partner, shareholder or member) of such entity; or (d) any Affiliate of such Subordinated Unitholder. “Family Member” means (a) any ancestor or descendent (including any stepchild or adopted child) of a Subordinated Unitholder; (b) any spouse of a Subordinated Unitholder or ancestor or descendent of a Subordinated Unitholder; (c) any descendent of a grandparent of a Subordinated Unitholder; (d) any spouse of any descendent of a grandparent of a Subordinated Unitholder; (e) any trust established for the primary benefit of a Subordinated Unitholder or any of the foregoing Persons; (f) in the case of a Subordinated Unitholder which is a trust, any beneficiary of such trust; (g) an entity which is controlled (whether by ownership of voting securities or contract or other arrangement) by the Subordinated Unitholder or any of the foregoing Persons; or (h) any organization described in Section 170(b)(1)(A), 170(c), 2055(a) or 2522(a) of the Code.

(g) Subject to (i) the foregoing provisions of this Section 4.5, (ii) Section 4.3, (iii) Section 4.7, (iv) Section 4.8, (v) with respect to any class or series of Limited Partner Interests, the provisions of any Supplemental Terms Annex, (vi) any contractual provisions binding on any Limited Partner, and (vii) provisions of applicable law including the Securities Act, Limited Partner Interests shall be freely transferable.

Section 4.6 Transfer of the General Partner Interest.

(a) The General Partner shall not transfer all or any part of its General Partner Interest to another Person (except a direct or indirect wholly-owned Subsidiary of the Partnership) and the Partnership shall not transfer all or any part of its equity interest in the General Partner to another Person (except a direct or indirect wholly-owned Subsidiary of the Partnership), in each case, without the consent of a Supermajority Vote of the Unitholders.

(b) Notwithstanding anything herein to the contrary, no transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound by the provisions of this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability under the Delaware Act of any Limited Partner or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the partnership or membership interest held by the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a transfer pursuant to and in compliance with this Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.2, be admitted to the Partnership as the General Partner effective immediately prior to the transfer of the General Partner Interest, and the business of the Partnership shall continue without dissolution.

Section 4.7 Restrictions on Transfers.

(a) Notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests shall be made if such transfer would (i) violate the then applicable U.S. federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership under the laws of the jurisdiction of its formation, or (iii) cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already so treated or taxed).

(b) The General Partner may impose restrictions on the transfer of Partnership Interests if the General Partner determines, with the advice of counsel, that such restrictions are necessary or advisable to (i) avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for U.S. federal income tax purposes or (ii) preserve the uniformity of Limited Partner Interests (or any class or classes thereof). The General Partner may impose such restrictions by amending this Agreement; provided, however, that any amendment that would result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or admitted to trading must be approved, prior to such amendment being effected, by the holders of a majority of the Outstanding Limited Partner Interests of such class.

(c) Nothing contained in this Agreement, other than Section 4.7(a), shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading.

Section 4.8 Eligibility Certificates; Ineligible Holders.

(a) If at any time the General Partner determines, with the advice of counsel, that:

(i) the Partnership not being treated as an association taxable as a corporation or otherwise taxable as an entity for U.S. federal income tax purposes, coupled with the tax status (or lack of proof thereof) of one or more Limited Partners (or type of Limited Partners) or their owners, has or is reasonably likely to have, a material adverse effect on the maximum applicable rates chargeable to customers by any Group Member (a “Rate Eligibility Trigger”); or

(ii) the nationality, citizenship or other related status (or lack of proof thereof) of one or more Limited Partners (or type of Limited Partners) or their owners creates or is reasonably likely to create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest under any federal, state or local law or regulation (a “Citizenship Eligibility Trigger”);

then, the General Partner may adopt such amendments to this Agreement as it determines to be necessary or appropriate to (x) in the case of a Rate Eligibility Trigger, obtain such proof of the U.S. federal income tax status of the Limited Partners and, to the extent relevant, their owners, as the General Partner determines to be necessary or appropriate to reduce the risk of occurrence of a material adverse effect on the rates that can be charged to customers by any Group Member or (y) in the case of a Citizenship Eligibility Trigger, obtain such proof of the nationality, citizenship or other related status of the Limited Partners and, to the extent relevant, their owners as the General Partner determines to be necessary or appropriate to eliminate or mitigate the risk of cancellation or forfeiture of any properties or interests therein.

(b) Such amendments may include provisions requiring all Partners to certify as to their (and their owners’) status as Eligible Holders upon demand and on a regular basis, as determined by the General Partner, and may require transferees of Units to so certify prior to being admitted to the Partnership as Partners (any such required certificate, an “Eligibility Certificate”).

(c) Such amendments may provide that any Partner who fails to furnish to the General Partner within a reasonable period requested proof of its (and its owners’) status as an Eligible Holder or if upon receipt of such Eligibility Certificate or other requested information the General Partner determines that a Limited Partner (or its owner) is not an Eligible Holder (an “Ineligible Holder”), the Partnership Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.9. In addition, the General Partner shall be substituted and treated as the owner of all Partnership Interests owned by an Ineligible Holder.

(d) The General Partner shall, in exercising voting rights in respect of Partnership Interests held by it on behalf of Ineligible Holders, cast such votes in the same manner and in the same ratios as the votes of Partners (including the General Partner and its Affiliates) in respect of Partnership Interests other than those of Ineligible Holders are cast.

(e) Upon dissolution of the Partnership, an Ineligible Holder shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Ineligible Holder’s share of any distribution in kind. Such payment and assignment shall be treated for purposes hereof as a purchase by the Partnership from the Ineligible Holder of the portion of his Partnership Interest representing his right to receive his share of such distribution in kind.

(f) At any time after he can and does certify that he has become an Eligible Holder, an Ineligible Holder may, upon application to the General Partner, request that with respect to any Partnership Interests of such Ineligible Holder not redeemed pursuant to Section 4.9, such Ineligible Holder be admitted as a Partner, and upon approval of the General Partner, such Ineligible Holder shall be admitted as a Partner and shall no longer constitute an Ineligible Holder and the General Partner shall cease to be deemed to be the owner in respect of such Ineligible Holder’s Partnership Interests.

(g) None of the provisions of this Section 4.8 or Section 4.9 apply with respect to the Preferred Units with the terms set forth in the Supplemental Terms Annex attached hereto as Annex A that is in effect as of the Closing Date.

Section 4.9 Redemption of Partnership Interests of Ineligible Holders.

(a) If at any time a Partner fails to furnish an Eligibility Certificate or other information requested within the period of time specified in amendments adopted pursuant to Section 4.8 or if upon receipt of such Eligibility Certificate, the General Partner determines, with the advice of counsel, that a Partner is an Ineligible Holder, the Partnership may, unless the Partner establishes to the satisfaction of the General Partner that such Partner is an Eligible Holder or has transferred his Limited Partner Interests to a Person who is an Eligible Holder and who furnishes an Eligibility Certificate to the General Partner prior to the date fixed for redemption as provided below, redeem the Partnership Interest of such Partner as follows:

(i) The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Partner, at his or her last address designated on the records of the Partnership or the Transfer Agent, as applicable, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon redemption of the Redeemable Interests (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender of the Certificate evidencing the Redeemable Interests) and that on and after the date fixed for redemption no further allocations or distributions to which the Partner would otherwise be entitled in respect of the Redeemable Interests will accrue or be made.

(ii) The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Partnership Interests of the class to be so redeemed multiplied by the number of Partnership Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 8% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

(iii) The Partner or his duly authorized representative shall be entitled to receive the payment for the Redeemable Interests at the place of payment specified in the notice of redemption on the redemption date (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender by or on behalf of the Partner at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank).

(iv) After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Limited Partner Interests.

(b) The provisions of this Section 4.9 shall also be applicable to Partnership Interests held by a Partner as nominee of a Person determined to be an Ineligible Holder.

(c) Nothing in this Section 4.9 shall prevent the recipient of a notice of redemption from transferring his Partnership Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided that the transferee of such Partnership Interest certifies to the satisfaction of the General Partner that he is an Eligible Holder. If the transferee fails to make such certification, such redemption will be effected from the transferee on the original redemption date.

CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS

Section 5.1 Contributions by the General Partner and its Affiliates.

(a) In connection with the formation of the Partnership under the Delaware Act, Black Stone Natural Limited Resources, L.L.C. (the “Original General Partner”) was admitted as the sole general partner of the Partnership and the Organizational Limited Partner was admitted as the sole Limited Partner in exchange for a Capital Contribution of $100. On November 21, 2014, the Original General Partner transferred its non-economic general partner interest in the Partnership to the General Partner pursuant to that certain Assignment of Partnership Interest, dated as of November 21, 2014 between the Original General Partner and the General Partner (which was consented to by the Organizational Limited Partner) and pursuant to such assignment, the General Partner was admitted as the sole general partner of the Partnership and the Partnership was continued without dissolution. On May 5, 2015, the General Partner made a Capital Contribution to the Partnership in the amount of $32,197,643.38 in exchange for a 1% Limited Partner Interest and was admitted as a Limited Partner. Immediately prior to the Effective Time, the General Partner’s 1% Limited Partner Interest is hereby converted into 733,670 Common Units and 960,943 Subordinated Units and the Organizational Limited Partner’s Limited Partner Interest is hereby converted into 1,000 Common Units.

(b) At the Effective Time, pursuant to this Agreement and/or the Merger and Contribution Agreement, (i) the Common Units held by the Organizational Limited Partner shall be redeemed and cancelled in exchange for a return of the Organizational Limited Partner’s initial Capital Contribution to the Partnership; (ii) Merger Sub shall merge with and into the Organizational Limited Partner; and (iii) the Partnership shall issue an aggregate of 72,633,333 Common Units and 95,133,333 Subordinated Units to the common unitholders of the Organizational Limited Partner and an aggregate of 117,980 Preferred Units with the terms set forth on the Supplemental Terms Annex attached hereto as Annex A and dated as of the date hereof to the preferred unitholders of the Organizational Limited Partner.

Section 5.2 Contributions by Underwriters.

(a) On the Closing Date and pursuant to the Underwriting Agreement, each Underwriter shall contribute cash to the Partnership in exchange for the issuance by the Partnership of Common Units to each Underwriter, all as set forth in the Underwriting Agreement.

(b) Upon the exercise, if any, of the Over-Allotment Option, each Underwriter shall contribute cash to the Partnership in exchange for the issuance by the Partnership of Common Units to each Underwriter, all as set forth in the Underwriting Agreement.

(c) No Limited Partner will be required to make any additional Capital Contribution to the Partnership pursuant to this Agreement.

Section 5.3 Interest and Withdrawal. No interest on Capital Contributions shall be paid by the Partnership. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon dissolution of the Partnership may be considered as

the withdrawal or return of its Capital Contribution by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions or as to profits, losses or distributions.

Section 5.4 Capital Accounts.

(a) The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made by the Partner with respect to such Partnership Interest, (ii) all items of Partnership income and gain computed in accordance with Section 5.4(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and (iii) the portion of any amount realized from the disposition of an oil and gas property that constitutes Simulated Gain allocated with respect to such Partnership Interest in accordance with Section 6.1(e)(iii) and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions to the Partner of cash or property made with respect to such Partnership Interest, provided that the Capital Account of a Partner shall not be reduced by the amount of any distributions made with respect to Restricted Common Units held by such Partner, (y) all items of Partnership deduction and loss computed in accordance with Section 5.4(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and (z) Simulated Depletion and Simulated Loss in accordance with Section 6.1(e)(ii).

(b) For purposes of computing the amount of any item of income, gain, loss, deduction, Simulated Depletion, Simulated Gain or Simulated Loss that is to be allocated pursuant to Article VI and is to be reflected in the Partners’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for U.S. federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided, that:

(i) Solely for purposes of this Section 5.4, the Partnership shall be treated as owning directly its proportionate share (as determined by the General Partner based upon the provisions of the applicable Group Member Agreement) of all property owned by (x) any other Group Member that is classified as a partnership for U.S. federal income tax purposes and (y) any other partnership, limited liability company, unincorporated business or other entity classified as a partnership for U.S. federal income tax purposes of which a Group Member is, directly or indirectly, a partner, member or other equity holder.

(ii) All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Partners pursuant to Section 6.1.

(iii) The computation of all items of income, gain, loss, deduction, Simulated Depletion, Simulated Gain and Simulated Loss shall be made (x) except as otherwise provided in this Agreement and Treasury Regulation Section 1.704-1(b)(2)(iv)(m), without regard to any election under Section 754 of the Code that may be made by the Partnership, and (y) as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for U.S. federal income tax purposes.

(iv) To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(l)) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

(v) In the event the Carrying Value of Partnership property is adjusted pursuant to Section 5.4(d), any Unrealized Gain resulting from such adjustment shall be treated as an item of gain and any Unrealized Loss resulting from such adjustment shall be treated as an item of loss.

(vi) Any income, gain, loss, Simulated Gain or Simulated Loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the property’s Carrying Value as of such date.

(vii) Any deductions for depreciation, amortization or other cost recovery attributable to any Contributed Property or Adjusted Property shall be determined under the rules prescribed by Treasury Regulation Section 1.704-3(d)(2) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment. Simulated Depletion will be computed in accordance with the provisions of the definition of Simulated Depletion.

(viii) The Gross Liability Value of each Liability of the Partnership described in Treasury Regulation Section 1.752-7(b)(3)(i) shall be adjusted at such times as provided in this Agreement for an adjustment to Carrying Values. The amount of any such adjustment shall be treated for purposes hereof as an item of loss (if the adjustment increases the Carrying Value of such Liability of the Partnership) or an item of gain (if the adjustment decreases the Carrying Value of such Liability of the Partnership).

(c)(i) Except as otherwise provided in this Section 5.4(c), a transferee of a Partnership Interest shall succeed to a Pro Rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred.

(ii) Subject to Section 6.8(b), immediately prior to the transfer of (i) a Subordinated Unit, (ii) a Common Unit that has been converted from a Subordinated Unit pursuant to Section 5.6 or (iii) any Other Convertible Unit that has converted into a Common Unit by a holder thereof (in each case, other than a transfer to an Affiliate unless the General Partner elects to have this Section 5.4(c)(ii) apply), the Capital Account maintained for such Person with respect to its Subordinated Units, Common Units converted from Subordinated Units or Common Units converted from Other Convertible Units, as the case may be, will (A) first, be allocated to the Subordinated Units, Common Units converted from Subordinated Units or Common Units converted from Other Convertible Units to be transferred in an amount equal to the product of (x) the number of such Subordinated Units, Common Units converted from Subordinated Units or Common Units converted from Other Convertible Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Subordinated Units, Common Units converted from Subordinated Units or Common Units converted from Other Convertible Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Subordinated Units, retained Common Units converted from Subordinated Units or retained Common Units converted from Other Convertible Units, if any, will have a balance equal to the amount allocated under clause (B) above, and the transferee’s Capital Account established with respect to the transferred Subordinated Units, transferred Common Units converted from Subordinated Units or transferred Common Units converted from Other Convertible Units will have a balance equal to the amount allocated under clause (A) above.

(d)(i) Consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(h)(2), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of a Noncompensatory Option, the issuance of Partnership Interests as consideration for the provision of services (including upon the lapse of a “substantial risk of forfeiture” with respect to a Restricted Common Unit) or the conversion of any Partnership Interests or Derivative Instruments issued pursuant to Section 5.5 to Common Units, the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property; provided, however, that in the event of the issuance of a Partnership Interest pursuant to the exercise of a Noncompensatory Option where the right to share in Partnership capital represented by such Partnership Interest differs from the consideration paid to acquire and exercise such option, the Carrying Value of each Partnership property immediately after the issuance of such Partnership Interest shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property and the Capital Accounts of the Partners shall be adjusted in a manner consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(s); provided further, however, that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed

Property, in the event of an issuance of a Noncompensatory Option to acquire a de minimis Partnership Interest, or in the event of an issuance of a de minimis amount of Partnership Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership. If, upon the occurrence of a Revaluation Event described in this Section 5.4(d), a Noncompensatory Option of the Partnership is Outstanding, the Partnership shall adjust the Carrying Value of each Partnership Property in accordance with Treasury Regulation Sections 1.704-1(b)(2)(iv)(f)(1) and 1.704-1(b)(2)(iv)(h)(2). In determining such Unrealized Gain or Unrealized Loss, the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests (or, in the case of a Revaluation Event resulting from the exercise of a Noncompensatory Option, immediately after the issuance of the Partnership Interest acquired pursuant to the exercise of such Noncompensatory Option) shall be determined by the General Partner using such method of valuation as it may adopt. In making its determination of the fair market values of individual properties, the General Partner may first determine an aggregate value for the assets of the Partnership that takes into account the current trading price of the Common Units, the fair market value of all other Partnership Interests at such time, and the amount of Partnership Liabilities. The General Partner may allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate). Absent a contrary determination by the General Partner, the aggregate fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately prior to a Revaluation Event shall be the value that would result in the Capital Account for each Common Unit that is Outstanding prior to such Revaluation Event being equal to the Event Issue Value.

(ii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of a distribution other than one made pursuant to Section 12.4 be determined in the same manner as that provided in Section 5.4(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined by the Liquidator using such method of valuation as it may adopt.

Section 5.5 Issuances of Additional Partnership Interests and Derivative Instruments

(a) Subject to the terms of a Supplemental Terms Annex, the Partnership may issue additional Partnership Interests (other than General Partner Interests) and Derivative Instruments for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partner.

(b) Each additional Partnership Interest authorized to be issued by the Partnership pursuant to Section 5.5(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior or junior to, or pari passu with existing classes and series of Partnership Interests), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may, or shall be required to, redeem the Partnership Interest (including sinking fund provisions); (v) whether such Partnership Interest is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Interest will be issued, evidenced by Certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Partnership Interest; and (viii) the right, if any, of each such Partnership Interest to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Interest. The rights and preferences of any additional class of Partnership Interests issued pursuant to this Section 5.5 shall be set forth in an annex to this Agreement (each, a “Supplemental Terms Annex”), the

provisions of which shall supplement and, to the extent inconsistent with any other provision of this Agreement, supersede the provisions hereof. To the extent that more than one Supplemental Terms Annex is in effect at any time and the terms of such Supplemental Terms Annexes conflict with each other, then the terms set forth in the most recently adopted Supplemental Terms Annex shall control.

(c) The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Partnership Interests and Derivative Instruments pursuant to this Section 5.5, (ii) the conversion of the General Partner’s general partner interest to Common Units (to the extent that the General Partner has an economic general partner interest) pursuant to the terms of this Agreement, or conversion to Common Units or, prior to the end of the Subordination Period, Subordinated Units, (iii) reflecting the admission of such additional Partners in the books and records of the Partnership as the Record Holder of such Partnership Interests, and (iv) all additional issuances of Partnership Interests. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Partnership Interests or in connection with the conversion of the General Partner’s general partner interest into Common Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Interests are listed or admitted to trading.

(d) No fractional Units shall be issued by the Partnership.

Section 5.6 Conversion of Subordinated Units

(a) If the Subordination Period expires in accordance with the provisions of Section 5.6(b), the Subordinated Units shall convert into such number of Common Units as is prescribed by Section 5.6(b) upon such expiration of the Subordination Period. If the Subordination Period expires in accordance with any provisions of this Agreement other than Section 5.6(b), then the Subordinated Units shall convert into Common Units on a one-for-one basis upon such expiration of the Subordination Period.

(b) At any time on or after August 30, 2019, provided that there are no Cumulative Common Unit Arrearages in respect of the Quarter immediately preceding such date and upon the election of the Board of Directors in its sole discretion, the outstanding Subordinated Units shall be converted into a number of Common Units to be determined by multiplying the number of outstanding Subordinated Units by a fraction, (i) the numerator of which is equal to the aggregate amount of distributions from Operating Surplus (not to exceed Adjusted Operating Surplus) on the outstanding Subordinated Units (“Historical Distributions”) for the four fiscal Quarters immediately preceding the date of conversion (the “Measurement Period”) and (ii) the denominator of which is equal to the aggregate amount of distributions that would have been required during the Measurement Period to pay the Minimum Quarterly Distribution on all outstanding Subordinated Units during such four-Quarter period; provided, that if the forecasted distributions to be paid from forecasted Operating Surplus (not to exceed forecasted Adjusted Operating Surplus) on the outstanding Subordinated Units for the four fiscal Quarter period immediately following the Measurement Period (“Forecasted Distributions”), as determined by the Conflicts Committee with the assistance of a nationally-recognized investment bank or financial advisor, is less than Historical Distributions, then the numerator shall be Forecasted Distributions (instead of Historical Distributions); provided, further, however, that the outstanding Subordinated Units may not convert into the Common Units at a ratio that is greater than one-to-one.

Section 5.7 Splits and Combinations

(a) The Partnership may make a distribution of Partnership Interests to all Record Holders or may effect a subdivision or combination of Partnership Interests. Upon any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event (subject to the effect of Section 5.7(d)), and any amounts calculated on a per Unit basis (including any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units shall be proportionately adjusted retroactively to the beginning of the Partnership.

(b) Whenever such a distribution, subdivision or combination of Partnership Interests is declared, the General Partner shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice.

(c) Promptly following any such distribution, subdivision, or combination, the Partnership may issue Certificates or uncertificated Partnership Interests to the Record Holders of Partnership Interests as of the applicable Record Date representing the new number of Partnership Interests held by such Record Holders, or the General Partner may adopt such other procedures that it determines to be necessary or appropriate to reflect such changes. If any such combination results in a smaller total number of Partnership Interests Outstanding, the Partnership shall require, as a condition to the delivery to a Record Holder of Partnership Interests represented by a Certificate, the surrender of any Certificate held by such Record Holder immediately prior to such Record Date.

(d) The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Partnership Interests. If a distribution, subdivision, combination or reorganization of Partnership Interests would result in the issuance of fractional Units but for the provisions of Section 5.5(d) and this Section 5.7(d), each fractional Unit shall be rounded to the nearest whole Unit (fractional units equal to or greater than a 0.5 Unit shall be rounded to the next higher Unit).

Section 5.8 Fully Paid and Non-Assessable Nature of Limited Partner Interests. All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Sections 17-303, 17-607 or 17-804 of the Delaware Act.

Section 5.9 Deemed Capital Contributions by Partners. Consistent with the provisions of Treasury Regulation Section 1.83-6(d), if any Partner (or its successor) transfers property (including cash) to any employee or other service provider of the Partnership Group and such Partner is not entitled to be reimbursed by (or otherwise elects not to seek reimbursement from) the Partnership for the value of such property, then (a) such property shall be treated as having been contributed to the Partnership by such Partner and (b) immediately thereafter the Partnership shall be treated as having transferred such property to the employee or other service provider.

Section 5.9 No Preemptive Rights. Except as may be provided in a separate agreement between the Partnership and another Person, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Interest, whether unissued, held in the treasury or hereafter created.

ARTICLE VI

ALLOCATIONS AND DISTRIBUTIONS

Section 6.1 Allocations for Capital Account Purposes. Subject to the terms of any Supplemental Terms Annex, for purposes of maintaining the Capital Accounts and in determining the rights of the Partners among themselves, the Partnership’s items of income, gain, loss, deduction, amount realized and Simulated Gain (computed in accordance with Section 5.4(b)) for each taxable period shall be allocated among the Partners, and the Capital Accounts of the Partners shall be adjusted for Simulated Depletion and Simulated Loss, as provided herein below. As set forth in the definition of “Outstanding,” Restricted Common Units shall not be considered to be Outstanding Common Units for purposes of this Section 6.1 and references herein to Unitholders holding Common Units shall be to such Unitholders solely with respect to their Common Units other than Restricted Common Units.

(a) Net Income. After giving effect to the Capital Account adjustments pursuant to Section 6.1(e)(ii), Net Income for each taxable period (including a pro rata part of each item of income, gain, loss, deduction and, to the extent provided in Section 6.1(e)(iii), Simulated Gain taken into account in computing Net Income for such taxable period) shall be allocated as follows:

(i) First, to the General Partner until the aggregate amount of Net Income allocated to the General Partner pursuant to this Section 6.1(a)(i) for the current and all previous taxable periods is equal to the aggregate amount of Net Loss allocated to the General Partner pursuant to Section 6.1(b)(ii) for all previous taxable periods; and

(ii) Second, the balance, if any, 100% to the Unitholders, Pro Rata.

(b) Net Loss. After giving effect to the Capital Account adjustments pursuant to Section 6.1(e)(ii), Net Loss for each taxable period (including a pro rata part of each item of income, gain, loss, deduction and, to the extent provided in Section 6.1(e)(iii), Simulated Gain taken into account in computing Net Loss for such taxable period) shall be allocated as follows:

(i) First, to the Unitholders, Pro Rata; provided, that Net Loss shall not be allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account); and

(ii) Second, the balance, if any, 100% to the General Partner.

(c) Net Termination Gains and Losses. After giving effect to the Capital Account adjustments pursuant to Section 6.1(e)(ii), Net Termination Gain or Net Termination Loss occurring during a taxable period shall be allocated in the manner set forth in this Section 6.1(c). All allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 and after all distributions of cash and cash equivalents provided under Sections 6.4 and 6.5 have been made; provided, however, that solely for purposes of this Section 6.1(c), Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4; and provided, further, that Net Termination Gain or Net Termination Loss attributable to (i) Liquidation Gain or Liquidation Loss shall be allocated on the last day of the taxable period during which such Liquidation Gain or Liquidation Loss occurred, (ii) Sale Gain or Sale Loss shall be allocated as of the time of the sale or disposition giving rise to such Sale Gain or Sale Loss and allocated to the Partners consistent with the second proviso set forth in Section 6.2(g) and (iii) Revaluation Gain or Revaluation Loss shall be allocated on the date of the Revaluation Event giving rise to such Revaluation Gain or Revaluation Loss.

(i) Except as provided in Section 6.1(c)(iv) and subject to the provisions set forth in the last sentence of this Section 6.1(c)(i), Net Termination Gain (including a pro rata part of each item of income, gain, loss, deduction and, to the extent provided in Section 6.1(e)(iii), Simulated Gain taken into account in computing Net Termination Gain) shall be allocated in the following order and priority:

(A) First, to each Partner having a deficit balance in its Adjusted Capital Account, in the proportion that such deficit balance bears to the total deficit balances in the Adjusted Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Adjusted Capital Account;

(B) Second, to all Unitholders holding Common Units, Pro Rata, until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Initial Unit Price, (2) if the Net Termination Gain is attributable to Liquidation Gain, the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Sections 6.4(a)(i) or 6.4(b) with respect to such Common Unit for such Quarter (the amount determined pursuant to this clause (2) is hereinafter referred to as the “Unpaid MQD”) and (3) any then existing Cumulative Common Unit Arrearage with respect to such Common Unit;

(C) Third, if such Net Termination Gain is recognized (or is deemed to be recognized) prior to the conversion of the last Outstanding Subordinated Unit into a Common Unit, to all Unitholders holding

Subordinated Units, Pro Rata, until the Capital Account in respect of each Subordinated Unit then Outstanding equals the sum of (1) its Unrecovered Initial Unit Price, determined for the taxable period (or portion thereof) to which this allocation of gain relates, and (2) if the Net Termination Gain is attributable to Liquidation Gain, the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Section 6.4(a)(iii) with respect to such Subordinated Unit for such Quarter; and

(D) Finally, 100% to all Unitholders, Pro Rata.

(ii) Except as otherwise provided by Sections 6.1(c)(iii) or 6.1(c)(iv), Net Termination Loss (including a pro rata part of each item of income, gain, loss, deduction and, to the extent provided in Section 6.1(e)(iii), Simulated Gain taken into account in computing Net Termination Loss) shall be allocated:

(A) First, if Subordinated Units remain Outstanding, to all Unitholders holding Subordinated Units, Pro Rata, until the Adjusted Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero;

(B) Second, to all Unitholders holding Common Units, Pro Rata, until the Adjusted Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; and

(iii) Net Termination Loss attributable to Revaluation Loss and deemed recognized prior to the conversion of the last Outstanding Subordinated Unit and prior to the Liquidation Date shall be allocated:

(A) First, to the Unitholders, Pro Rata, until the Capital Account in respect of each Common Unit then Outstanding equals the Event Issue Value; provided that Net Termination Loss shall not be allocated pursuant to this Section 6.1(c)(iii)(A) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit in its Adjusted Capital Account);

(B) Second, to all Unitholders holding Subordinated Units, Pro Rata; provided that Net Termination Loss shall not be allocated pursuant to this Section 6.1(c)(iii)(B) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit in its Adjusted Capital Account); and

(iv) If (A) a Net Termination Loss has been allocated pursuant to Section 6.1(c)(iii), (B) a Net Termination Gain or Net Termination Loss subsequently occurs (other than as a result of a Revaluation Event) prior to the conversion of the last Outstanding Subordinated Unit and (C) after tentatively making all allocations of such Net Termination Gain or Net Termination Loss provided for in Sections 6.1(c)(i) or 6.1(c)(ii), as applicable, the Capital Account in respect of each Common Unit then Outstanding does not equal the amount such Capital Account would have been if Section 6.1(c)(iii) had not been part of this Agreement and all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Sections 6.1(c)(i) or 6.1(c)(ii), as applicable, then items of income, gain, loss and deduction included in such Net Termination Gain or Net Termination Loss, as applicable, shall be specially allocated to the General Partner and all Unitholders in a manner that will, to the maximum extent possible, cause the Capital Account in respect of each Common Unit then Outstanding to equal the amount such Capital Account would have been if all allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Sections 6.1(c)(i) or 6.1(c)(ii), as applicable.

(d) Special Allocations. Notwithstanding any other provision of this Section 6.1, the following special allocations shall be made for each taxable period in the following order:

(i) Partnership Minimum Gain Chargeback. Notwithstanding any other provision of this Section 6.1, if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income, gain and Simulated Gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6),

1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income, gain and Simulated Gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d) with respect to such taxable period (other than an allocation pursuant to Sections 6.1(d)(vi) and 6.1(d)(vii)). This Section 6.1(d)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(ii) Chargeback of Partner Nonrecourse Debt Minimum Gain. Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income, gain and Simulated Gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income, gain and Simulated Gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d), other than Section 6.1(d)(i) and other than an allocation pursuant to Sections 6.1(d)(vi) and 6.1(d)(vii), with respect to such taxable period. This Section 6.1(d)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Priority Allocations. If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4) with respect to an Outstanding Unit for a taxable period exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Outstanding Unit for the same taxable period (the amount of the excess, an “Excess Distribution” and the Unit with respect to which the greater distribution is paid, an “Excess Distribution Unit”), then there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution.

(iv) Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(iii) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(iii) were not in this Agreement.

(v) Gross Income Allocations. In the event any Partner has a deficit balance in its Capital Account at the end of any taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income, gain and Simulated Gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account after all other allocations provided for in this Section 6.1 have been tentatively made as if Section 6.1(d)(iii) and this Section 6.1(d)(v) were not in this Agreement.

(vi) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Partners, Pro Rata. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations

promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements.

(vii) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss. This Section 6.1(d)(vii) is intended to comply with Treasury Regulations Section 1.704-2(i)(1) and shall be interpreted consistently therewith.

(viii) Nonrecourse Liabilities. For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners, Pro Rata.

(ix) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts as a result of a distribution to a Partner in complete liquidation of such Partner’s interest in the Partnership, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain or Simulated Gain (if the adjustment increases the basis of the asset) or loss or Simulated Loss (if the adjustment decreases such basis) taken into account pursuant to Section 5.4, and such item of gain, loss, Simulated Gain or Simulated Loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(x) Economic Uniformity; Changes in Law.

(A) At the election of the General Partner with respect to any taxable period ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the proportion of the number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such Final Subordinated Units to an amount that after taking into account the other allocations of income, gain, loss and deduction to be made with respect to such taxable period will equal the product of (i) the number of Final Subordinated Units held by such Partner and (ii) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Final Subordinated Units into Common Units. This allocation method for establishing such economic uniformity will be available to the General Partner only if the method for allocating the Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.4(c)(ii) does not otherwise provide such economic uniformity to the Final Subordinated Units.

(B) For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (iii) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or

classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.1(d)(x) only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Outstanding Limited Partner Interests or the Partnership.

(xi) Curative Allocation.

(A) Notwithstanding any other provision of this Section 6.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of gross income, gain, loss, deduction, Simulated Depletion, Simulated Gain and Simulated Loss allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Section 6.1 and Simulated Depletion and Simulated Loss had been included in the definition of Net Income and Net Loss. In exercising its discretion under this Section 6.1(d)(xi)(A), the General Partner may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made. Allocations pursuant to this Section 6.1(d)(xi)(A) shall only be made with respect to Required Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners.

(B) The General Partner shall, with respect to each taxable period, (1) apply the provisions of Section 6.1(d)(xi)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xi)(A) among the Partners in a manner that is likely to minimize such economic distortions.

(xii) Special Curative Allocation in Event of Certain Liquidations. Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (1) the Liquidation Date occurs prior to the conversion of the last Outstanding Subordinated Unit and (2) after having made all other allocations provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs, the Capital Account in respect of each then Outstanding Common Unit does not equal the amount such Capital Account would have been if Sections 6.1(c)(iii) and 6.1(c)(iv) had not been part of this Agreement and all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Sections 6.1(c)(i) or 6.1(c)(ii), as applicable, then items of income, gain, loss and deduction for such taxable period shall be reallocated among all Unitholders in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Sections 6.1(c)(i) or 6.1(c)(ii), as applicable. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Capital Account balances described above, (x) items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs shall be reallocated from the Unitholders holding Subordinated Units to Unitholders holding Common Units and (y) items of deduction and loss that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs shall be reallocated from Unitholders holding Common Units to Unitholders holding Subordinated Units. In the event that (1) the Liquidation Date occurs on or before the date (not including any extension of time prescribed by law) for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (2) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xii) fails to achieve the Capital Account balances described above, items of income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among the General Partner and all Unitholders in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xii), cause the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Sections 6.1(c)(i) or 6.1(c)(ii), as applicable.

(xiii) Allocations of GP Items. All GP Items shall, to the maximum extent possible, be allocated to the holders (other than the General Partner) of the Common Units, Pro Rata.

(xiv) Equalization of Capital Accounts With Respect to Privately Placed Units. Unrealized Gain or Unrealized Loss deemed recognized as a result of a Revaluation Event shall first be allocated to the (A) Unitholders holding Privately Placed Units, Pro Rata, or (B) Unitholders holding Common Units (other than Privately Placed Units), Pro Rata, as applicable, to the extent necessary to cause the Capital Account in respect of each Privately Placed Unit then Outstanding to equal the Capital Account in respect of each Common Unit (other than Privately Placed Units) then Outstanding.

(xv) Allocations Regarding Certain Payments Made to Employees and Other Service Providers. Consistent with the provisions of Treasury Regulation Section 1.83-6(d), if any Partner (or its successor) transfers property (including cash) to any employee or other service provider of the Partnership Group and such Partner is not entitled to be reimbursed by (or otherwise elects not to seek reimbursement from) the Partnership for the value of such property, then any items of deduction or loss resulting from or attributable to such transfer shall be allocated to the Partner (or its successor) that made such transfer and was deemed to have contributed such property to the Partnership pursuant to Section 5.9.

(e) Simulated Basis; Simulated Depletion and Simulated Loss; Simulated Gain; Amount Realized.

(i) Simulated Basis. For purposes of determining and maintaining the Partners’ Capital Accounts, (i) the initial Simulated Basis of each oil and gas property (as defined in Section 614 of the Code) of the Partnership shall be allocated among the Partners, Pro Rata and (ii) if the Carrying Value of an oil and gas property (as defined in Section 614 of the Code) is adjusted pursuant to Section 5.4(d), the Simulated Basis of such property (as adjusted to reflect the adjustment to the Carrying Value of such property), shall be allocated to the Partners, Pro Rata.

(ii) Simulated Depletion and Simulated Loss. For purposes of applying clause (z) of the second sentence of Section 5.4(a), Simulated Depletion and Simulated Loss with respect to each oil and gas property (as defined in Section 614 of the Code) of the Partnership shall reduce each Partner’s Capital Account in proportion to the manner in which the Simulated Basis of such property is allocated among the Partners pursuant to Section 6.1(e)(i).

(iii) Simulated Gain. For purposes of applying clause (iii) of the second sentence of Section 5.4(a), Simulated Gain for any taxable period will be treated as included in either Net Income or Net Loss and allocated pursuant to Sections 6.1(a) and 6.1(b).

(iv) Amount Realized. For purposes of Treasury Regulation Sections 1.704-1(b)(2)(iv)(k)(2) and 1.704-1(b)(4)(iii), the amount realized on the disposition of any oil and gas property (as defined in Section 614 of the Code) of the Partnership shall be allocated (i) first to the Partners in an amount equal to the remaining Simulated Basis of such property in the same proportions as the Simulated Basis of such property was allocated among the Partners pursuant to Section 6.1(e)(i), and (ii) any remaining amount realized shall be allocated to the Partners in the same ratio as Simulated Gain from the disposition of such oil and gas property is allocated pursuant to Section 6.1(a).

Section 6.2 Allocations for Tax Purposes. Subject to the terms of any Supplemental Terms Annex, allocations for U.S. federal income tax purposes shall be made as set forth in this Section 6.2.

(a) Except as otherwise provided herein, for U.S. federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1.

(b) The deduction for depletion with respect to each separate oil and gas property (as defined in Section 614 of the Code) shall be computed for federal income tax purposes separately by the Partners rather than by the Partnership in accordance with Section 613A(c)(7)(D) of the Code. Except as provided in Section 6.2(c), for

purposes of such computation (before taking into account any adjustments resulting from an election made by the Partnership under Section 754 of the Code), the adjusted tax basis of each oil and gas property (as defined in Section 614 of the Code) that is (i) a Contributed Property shall initially be allocated among the non-contributing Partners, Pro Rata, but not in excess of any such Partner’s share of Simulated Basis as determined pursuant to Section 6.1(e)(i), and (ii) not a Contributed Property or an Adjusted Property shall initially be allocated to the Partners in proportion to each such Partner’s share of Simulated Basis as determined pursuant to Section 6.1(e)(i). If there is an event described in Section 5.4(d), the General Partner shall reallocate the adjusted tax basis of each oil and gas property in a manner (i) consistent with the principles of Section 704(c) of the Code and (ii) that maintains the federal income tax fungibility of the Units.

Each Partner shall separately keep records of his share of the adjusted tax basis in each oil and gas property, allocated as provided above, adjust such share of the adjusted tax basis for any cost or percentage depletion allowable with respect to such property, and use such adjusted tax basis in the computation of its cost depletion or in the computation of his gain or loss on the disposition of such property by the Partnership

(c) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for U.S. federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations promulgated under Section 704(b) and 704(c) of the Code, as determined appropriate by the General Partner (taking into account the General Partner’s discretion under Section 6.1(d)(x)); provided that, in all events, the General Partner shall apply the “remedial allocation method” in accordance with the principles of Treasury Regulation Section 1.704-3(d). For purposes of applying the “remedial allocation method” to oil and gas properties (i) the amount by which any Partner’s Capital Account is adjusted for Simulated Depletion shall be treated as an amount of book depletion allocated to such Partner and (ii) the amount of cost depletion computed by such Partner under Section 613A(c)(7)(D) of the Code shall be treated as an amount of tax depletion allocated to such Partner.

(d) The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or any successor regulations thereto. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Units, so long as such conventions would not have a material adverse effect on the Limited Partners or Record Holders of any class or classes of Limited Partner Interests.

(e) In accordance with Treasury Regulation Sections 1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2, be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

(f) All items of income, gain, loss, deduction and credit recognized by the Partnership for U.S. federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code that may be made by the Partnership; provided, however, that such allocations, once made, shall be adjusted (in the manner determined by the General Partner) to take into account those adjustments permitted or required by Sections 734 and 743 of the Code.

(g) Each item of Partnership income, gain, loss and deduction shall, for U.S. federal income tax purposes, be determined for each Quarter and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership’s Units are listed or admitted to trading on the first Business Day of each month; provided, however, such items for the period beginning on the Closing Date and ending on the last day of the month in which the Closing Date occurs shall be allocated to the Partners who are issued Units as a result of the transactions contemplated by the Contribution Agreement and the Underwriting Agreement; and provided, further, that each item of Partnership income, gain, loss and deduction for the period beginning on the Contribution Date and ending the date immediately before the Closing Date shall be allocated to the Partners holding Units on the date immediately before the Closing Date; and provided, further, that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income, gain, loss or deduction, as determined by the General Partner, shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership’s Units are listed or admitted to trading on the first Business Day of the month in which such item is recognized for U.S. federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

(h) Allocations that would otherwise be made to a Partner under the provisions of this Article VI shall instead be made to the beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method determined by the General Partner.

(i) If, as a result of an exercise of a Noncompensatory Option, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

Section 6.3 Distributions; Characterization of Distributions; Distributions to Record Holders.

(a) The General Partner may adopt a cash distribution policy, which it may change from time to time without amendment to this Agreement.

(b) All amounts of cash and cash equivalents distributed by the Partnership, except for distributions and other payments with respect to Partnership Interests with a right to receive distributions in priority or senior to the Common Units, which in accordance with clause (e) of the definition of Operating Expenditures shall be treated as payment of interest, principal or premium on indebtedness, and not as distributions of Operating Surplus, on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of cash and cash equivalents theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 equals the Operating Surplus from the Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of cash and cash equivalents distributed by the Partnership on such date shall, except as otherwise provided in Section 6.5, be deemed to be “Capital Surplus.” All distributions required to be made under this Agreement or otherwise made by the Partnership shall be made subject to Sections 17-607 and 17-804 of the Delaware Act.

(c) Notwithstanding Section 6.3(b), in the event of the dissolution and liquidation of the Partnership, cash shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4.

(d) Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through any Transfer Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date established for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

Section 6.4 Distributions from Operating Surplus.

(a) During Subordination Period. Subject to the terms of any Supplemental Terms Annex, cash and cash equivalents (other than GP Available Cash) distributed in respect of any Quarter wholly within the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Sections 6.3 or 6.5 shall be distributed as follows:

(i) First, to all Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(ii) Second, to all Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage existing with respect to such Quarter;

(iii) Third, to all Unitholders holding Subordinated Units, Pro Rata, until there has been distributed in respect of each Subordinated Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; and

(iv) Fourth, to all Unitholders, Pro Rata.

(b) After Subordination Period. Subject to the terms of any Supplemental Terms Annex, cash and cash equivalents (other than GP Available Cash) distributed in respect of any Quarter ending after the Subordination Period has ended shall be distributed to all Unitholders holding Common Units, Pro Rata.

Section 6.5 Distributions from Capital Surplus. Subject to the terms of any Supplemental Terms Annex, cash and cash equivalents (other than GP Available Cash) that are distributed and deemed to be Capital Surplus pursuant to the provisions of Section 6.3(b) shall be distributed, unless the provisions of Section 6.3 require otherwise:

(a) First, 100% to the Unitholders, Pro Rata, until the Minimum Quarterly Distribution has been reduced to zero;

(b) Second, 100% to all Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage; and

(c) Thereafter, all cash and cash equivalents that are distributed shall be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.4.

Section 6.6 Distributions of GP Available Cash. Distributions of cash and cash equivalents that are GP Available Cash shall be made in the same manner as set forth above, except that the General Partner shall not be entitled to participate in any such distribution.

Section 6.7 Adjustment of Common Unit Arrearages, Cumulative Common Arrearages and Minimum Quarterly Distributions. The Common Unit Arrearages and Cumulative Common Unit Arrearages shall be proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Common Units. In the event of a distribution that is deemed to be from Capital Surplus, the then applicable Minimum Quarterly Distributions shall be reduced in the same proportion that the amount or value of distribution per Unit bears to the Current Market Price per Common Unit immediately prior to the declaration of the distribution.

Section 6.8 Special Provisions Relating to the Holders of Subordinated Units.

(a) Except with respect to the right to vote on or approve matters requiring the vote or approval of a percentage of the holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Subordinated Unit

shall have all of the rights and obligations of a Unitholder holding Common Units hereunder; provided, however, that immediately upon the conversion of Subordinated Units into Common Units pursuant to Section 5.6, the Unitholder holding Common Units converted from Subordinated Units shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder with respect to such Common Units converted from Subordinated Units, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided, however, that such Common Units converted from Subordinated Units shall remain subject to the provisions of Sections 5.4(c)(ii), 6.1(d)(x), 6.8(b) and 6.8(c).

(b) A Unitholder shall not be permitted to transfer (i) a Subordinated Unit, (ii) Common Units converted from Subordinated Units pursuant to Section 5.5 or (iii) any Common Units converted from Other Convertible Units (other than a transfer to an Affiliate) if the remaining balance in the transferring Unitholder’s Capital Account with respect to the retained Subordinated Units, retained Common Units converted from Subordinated Units or retained Common Units converted from Other Convertible Units, as applicable, would be negative after giving effect to the allocation under Section 5.4(c)(ii)(B).

(c) The Unitholder holding a Common Unit that has resulted from the conversion of either a Subordinated Unit pursuant to Section 5.6 or any Other Convertible Unit shall not be permitted to transfer such Common Unit to a Person that is not an Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that each such Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.8(c), the General Partner may take whatever steps are required to provide economic uniformity to such Common Units in preparation for a transfer of such Common Units, including the application of Sections 5.4(c)(ii) and 6.1(d)(x); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units.

(xvii) the dissolution and winding up of the Partnership.

(b) Notwithstanding any other provision of this Agreement, any Group Member Agreement, the Delaware Act or any applicable law, rule or regulation, each of the Partners, each other Person who acquires an interest in a Partnership Interest and each other Person bound by this Agreement hereby (i) approves, ratifies and confirms the execution, delivery and performance by the parties thereto of this Agreement, the Underwriting Agreement, the Merger and Contribution Agreement, the Registration Rights Agreement and the other agreements described in or filed as exhibits to the Registration Statement that are related to the transactions contemplated by the Registration Statement (in the case of each agreement other than this Agreement, without giving effect to any amendments, supplements or restatements after the date hereof); (ii) agrees that the General Partner (on its own behalf or on behalf of the Partnership) is authorized to execute, deliver and perform the agreements referred to in clause (i) of this sentence and the other agreements, acts, transactions and matters described in or contemplated by the Registration Statement on behalf of the Partnership without any further act, approval or vote of the Partners, the other Persons who may acquire an interest in Partnership Interests or are otherwise bound by this Agreement; and (iii) agrees that the execution, delivery or performance by the General Partner, any Group Member or any Affiliate of any of them of this Agreement or any agreement authorized or permitted under this Agreement shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Partners or any other Persons under this Agreement (or any other agreements) or of any duty existing at law, in equity or otherwise.

Section 7.2 Replacement of Fiduciary Duties. Notwithstanding any other provision of this Agreement, to the extent that, at law or in equity, the General Partner or any other Indemnitee would have duties (including fiduciary duties) to the Partnership, to another Partner, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement, all such duties (including fiduciary duties) are hereby eliminated, to the fullest extent permitted by law, and replaced with the duties expressly set forth herein. The elimination of duties (including fiduciary duties) and replacement thereof with the duties expressly set forth herein are approved by the Partnership, each of the Partners, each other Person who acquires an interest in a Partnership Interest and each other Person bound by this Agreement.

In furtherance of this replacement of fiduciary duties, but not by way of limitation, the following provisions shall apply:

(a) It will not constitute a breach of fiduciary or other duty for the General Partner or the Partnership’s or the General Partner’s Officers or employees to engage attorneys, accountants and other advisors on behalf of the Partnership, even though such Persons may also be retained from time to time by the General Partner, any of its officers, members, or the Directors, or any of the Partnership’s or the General Partner’s Officers or employees, and such Persons may be engaged with respect to any matter in which the interest of the Partnership and the General Partner, any of its officers, members, or the Directors, or any of the Partnership’s or the General Partner’s Officers or employees, may differ, or may be engaged by both the Partnership and the General Partner or the Officers or employees of the Partnership or the General Partner with respect to any other matter. The General Partner shall not be responsible for any misconduct or negligence on the part of any such attorney, accountant or other advisor so long as the engagement of such Person was not made in Bad Faith;

(b) It will not constitute a breach of fiduciary or other duty for the General Partner, the Partnership’s or the General Partner’s Officers or employees, or any of their respective Affiliates, to contract or enter into any agreement or arrangement with the Partnership with respect to any Property or any aspect of the operations of the Partnership; and

(c) It will not constitute a breach of fiduciary or other duty for the General Partner or an Officer or employee of the Partnership or the General Partner to devote any amount of time to any other matters not related to the operations of the Partnership, and the General Partner or an Officer or employee of the Partnership or the General Partner may devote such time to the business and affairs of the Partnership as it determines necessary in its sole discretion.

Section 7.3 Certificate of Limited Partnership. The General Partner has caused the Certificate of Limited Partnership to be filed with the Secretary of State of the State of Delaware as required by the Delaware Act. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents that the General Partner determines to be necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent the General Partner determines such action to be necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.4(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Partner.

Section 7.4 Restrictions on the General Partner’s Authority. Except as provided in Articles XII and XIV, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the assets of the Partnership Group, taken as a whole, in a single transaction or a series of related transactions without the approval of a Unit Majority; provided, however, that this provision shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership Group and shall not apply to any sale of any or all of the assets of the Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance.

Section 7.5 Reimbursement of the General Partner.

(a) The General Partner and its Affiliates shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine, for (i) all direct and indirect expenses they incur or payments they make on behalf of the Partnership Group (including salary, bonus, incentive compensation and other amounts paid to any Person (including Affiliates of the General Partner) to perform services for the Partnership Group or for the General Partner in the discharge of its duties to the Partnership Group), and (ii) all other expenses allocable to the Partnership Group or otherwise incurred by the General Partner in connection with operating the Partnership Group’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the Partnership Group. Reimbursements pursuant to this Section 7.5 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7.

(b) The General Partner and its Affiliates may charge any member of the Partnership Group a management fee to the extent necessary to allow the Partnership Group to reduce the amount of any state franchise or income tax or any tax based upon the revenues or gross margin of any member of the Partnership Group if the tax benefit produced by the payment for such management fee of such management fee or fees exceeds the amount of such fee or fees.

(c) The General Partner, without the approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership benefit plans, programs and practices (including plans, programs and practices involving the issuance of Partnership Interests or Derivative Instruments), or cause the Partnership to issue Partnership Interests or Derivative Instruments in connection with, or pursuant to, any benefit plan, program or practice maintained or sponsored by the General Partner or any of its Affiliates, any Group Member or their Affiliates, or any of them, in each case for the benefit of employees, officers, consultants and directors of the General Partner or its Affiliates, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its Affiliates any Partnership Interests or Derivative Instruments that the General Partner or such Affiliates are obligated to provide to any employees, officers, consultants and directors pursuant to any such benefit plans, programs or practices. Expenses incurred by the General Partner in connection with

any such plans, programs and practices (including the net cost to the General Partner or such Affiliates of Partnership Interests or Derivative Instruments purchased by the General Partner or such Affiliates, from the Partnership or otherwise, to fulfill awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.5(a). Any and all obligations of the General Partner under any benefit plans, programs or practices adopted by the General Partner as permitted by this Section 7.5(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or the transferee of or successor to all of the General Partner’s General Partner Interest pursuant to Section 4.6.

Section 7.6 Outside Activities.

(a) The General Partner, for so long as it is the General Partner of the Partnership, shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (i) its performance as general partner or managing member, if any, of one or more Group Members or as described in or contemplated by the Registration Statement, (ii) the acquiring, owning or disposing of debt securities or equity interests in any Group Member or (iii) the direct or indirect provision of management, advisory, and administrative services to its Affiliates or to other Persons.

(b) Each Unrestricted Person (other than the Persons described in Section 7.6(e)) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member. No such business interest or activity shall constitute a breach of this Agreement, any fiduciary or other duty existing at law, in equity or otherwise, or obligation of any type whatsoever to the Partnership or other Group Member, to another Partner, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement.

(c) Notwithstanding anything to the contrary in this Agreement, the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to any Unrestricted Person (including the Persons described in Section 7.6(e)). No Unrestricted Person (including the Persons described in Section 7.6(e)) who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to any Group Member, and such Unrestricted Person (including the Persons described in Section 7.6(e)) shall not be liable to the Partnership or other Group Member, to another Partner, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement for breach of any fiduciary or other duty existing at law, in equity or otherwise by reason of the fact that such Unrestricted Person (including the Persons described in Section 7.6(e)) pursues or acquires such opportunity for itself, directs such opportunity to another Person or does not communicate such opportunity or information to any Group Member.

(d) Subject to the terms of Sections 7.6(a), 7.6(b), 7.6(c), and 7.6(e), but otherwise notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Unrestricted Person in accordance with the provisions of this Section 7.6 is hereby approved by the Partnership and all Partners, and (ii) it shall be deemed not to be a breach of any fiduciary duty or any other duty or obligation of any type whatsoever of the General Partner or of any other Unrestricted Person for the Unrestricted Person to engage in such business interests and activities in preference to or to the exclusion of the Partnership; provided such Unrestricted Person does not engage in such business or activity as a result of or using confidential or proprietary information provided by or on behalf of the Partnership to such Unrestricted Person.

(e) Neither the General Partner nor any Director who is also an employee of the Partnership, the General Partner or any of their respective controlled Affiliates, nor any Affiliate of any such Director, may engage in, conduct or participate in any business or activity which may be competitive in any material respect with the business of the Partnership; provided, however, that any such Director or Affiliate may own a financial interest in

a competitor of the Partnership if that interest is in the form of ownership of less than 5% of the outstanding stock of a company whose securities are listed on a National Securities Exchange. Notwithstanding the foregoing, if an employee who is a Director has presented a business opportunity to the Partnership and the General Partner has determined not to pursue such business opportunity, then such Director, or his or her Affiliates, shall be permitted to pursue and conduct such business opportunity with the approval of the Board of Directors.

Section 7.7 Indemnification.

(a) To the fullest extent permitted by law, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities (joint or several), expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as an Indemnitee and acting (or refraining to act) in such capacity; provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Agreement, the Indemnitee acted in Bad Faith or engaged in willful misconduct or fraud or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification.

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in appearing at, participating in or defending any claim, demand, action, suit or proceeding shall, from time to time, on a monthly basis be advanced by the Partnership prior to a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee is not entitled to be indemnified upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 7.7.

(c) The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Outstanding Limited Partner Interests, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

(d) The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates, the Indemnitees and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e) For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law

shall constitute “fines” within the meaning of Section 7.7(a); and action taken or omitted by an Indemnitee with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Partnership.

(f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

(g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(h) The provisions of this Section 7.7 are for the benefit of the Indemnitees and their heirs, successors, permitted assigns, executors and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(i) No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.8 Limitation of Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, any Group Member Agreement, or under the Delaware Act or any other law, rule or regulation or at equity, no Indemnitee shall be liable for monetary damages or otherwise to the Partnership, to another Partner, to any other Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement, for losses sustained or liabilities incurred, of any kind or character, as a result of its or any of any other Indemnitee’s determinations, act(s) or omission(s) in their capacities as Indemnitees; provided, however, that an Indemnitee shall be liable for losses or liabilities sustained or incurred by the Partnership, the other Partners, any other Persons who acquire an interest in a Partnership Interest or any other Person bound by this Agreement, if it is determined by a final and non-appealable judgment entered by a court of competent jurisdiction that such losses or liabilities were the result of the conduct of that Indemnitee engaged in by it in Bad Faith or engaged in willful misconduct or fraud or, with respect to any criminal conduct, with the knowledge that its conduct was unlawful.

(b) The General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner if such appointment was not made in Bad Faith.

(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership, to the Partners, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement, the General Partner and any other Indemnitee acting in connection with the Partnership’s business or affairs shall not be liable to the Partnership, to any Partner, to any Person who acquires an interest in a Partnership Interest or to any other Person bound by this Agreement for its reliance on the provisions of this Agreement.

(d) Any amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.9 Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties.

(a) Whenever the General Partner, any Director, the Board of Directors or any committee of the Board of Directors (including the Conflicts Committee), or any Officer of the General Partner (collectively, the “Designated Persons”) causes the General Partner to make a determination or take or omit to take any action in its capacity as general partner of the Partnership, whether or not under this Agreement, any Group Member Agreement or any other agreement contemplated hereby, then, unless another lesser standard is provided for in this Agreement, such Designated Person, shall make such determination, or take or omit to take such action, in Good Faith. The foregoing and other lesser standards provided for in this Agreement are the sole and exclusive standards governing any such determinations, actions and omissions of the Designated Persons and no such Person shall be subject to any fiduciary duty or other duty or obligation, or any other, different or higher standard (all of which duties, obligations and standards are hereby waived and disclaimed), under this Agreement, any Group Member Agreement or any other agreement contemplated hereby, or under the Delaware Act or any other law, rule or regulation or at equity. Any such determination, action or omission by a Designated Person, will for all purposes be presumed to have been in Good Faith. In any proceeding brought by or on behalf of the Partnership, any Limited Partner, or any other Person who acquires an interest in a Partnership Interest or any other Person who is bound by this Agreement, challenging such determination, act or omission, the Person bringing or prosecuting such proceeding shall have the burden of proving that such determination, action or omission was not in Good Faith.

(b) A Designated Person may in its discretion submit any determination, action or omission that would otherwise be decided by such Designated Person pursuant to Section 7.9(a) (i) for Special Approval or (ii) for approval by the vote of a majority of the Common Units (excluding Common Units owned by the General Partner or its Affiliates). If a Designated Person does not submit the determination, action or omission as provided in either clauses (i) or (ii) in the preceding sentence, then any such determination, action or omission shall be governed by Section 7.9(a) above. If any determination, action or omission: (A) receives Special Approval; or (B) receives the approval of a majority of the Common Units, then such determination, action or omission shall be conclusively deemed to be approved by the Partnership, all the Partners, each Person who acquires an interest in a Partnership Interest and each other Person who is bound by this Agreement, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any fiduciary or other duty or obligation existing at law, in equity or otherwise or obligation of any type whatsoever. If Special Approval is not sought and the Board of Directors of the General Partner determines that the resolution or course of action taken with respect to a conflict of interest is either on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or is fair and reasonable to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership), then it shall be presumed that, in making its decision, the General Partner and the Board of Directors acted in Good Faith, and in any proceeding brought by any Limited Partner or Assignee or by or on behalf of such Limited Partner or Assignee or the Partnership challenging such approval, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption. Notwithstanding anything to the contrary in this Agreement or any duty otherwise existing at law or equity, the existence of the conflicts of interest described in the Registration Statement are hereby approved by all Partners and shall not constitute a breach of this Agreement or of any duty or obligation, express or implied, under applicable law.

(c) Notwithstanding anything to the contrary in this Agreement, the General Partner and its Affiliates or any other Indemnitee shall have no duty or obligation, express or implied, to (i) sell or otherwise dispose of any asset of the Partnership Group or (ii) permit any Group Member to use any facilities or assets of the General Partner and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with such use. Any determination by the General Partner or any of its Affiliates to enter into such contracts or transactions shall be in its sole discretion.

(d) The Partners, and each Person who acquires an interest in a Partnership Interest or is otherwise bound by this Agreement hereby authorize the General Partner, on behalf of the Partnership as a partner or member of a

Group Member, to approve actions by the general partner or managing member of such Group Member similar to those actions permitted to be taken by the General Partner pursuant to this Section 7.9.

(e) For the avoidance of doubt, whenever any Designated Person makes a determination on behalf of the General Partner, or causes the General Partner to take or omit to take any action, whether in the General Partner’s capacity as the General Partner or in its individual capacity, the standards of care applicable to the General Partner shall apply to such Person, and such Person shall be entitled to all benefits and rights of the General Partner hereunder, including waivers and modifications of duties, protections and presumptions, as if such Person were the General Partner hereunder.

Section 7.10 Other Matters Concerning Standards of Conduct.

(a) Each Designated Person may rely, and shall be protected in acting or refraining from acting upon, any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties.

(b) Each Designated Person may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it (collectively, “Experts”), and any act taken or omitted to be taken in reliance upon the advice or opinion (including an Opinion of Counsel) of such Experts as to matters that the Designated Person reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in Good Faith and in accordance with such advice or opinion.

(c) The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its or the Partnership’s duly authorized officers, a duly appointed attorney or attorneys-in-fact.

Section 7.11 Purchase or Sale of Partnership Interests. The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Interests or Derivative Instruments. As long as any Partnership Interests are held by any Group Member, such Partnership Interests shall not be entitled to any vote and shall not be considered to be Outstanding.

Section 7.12 Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner and any officer of the General Partner authorized by the General Partner to act on behalf of and in the name of the Partnership has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any authorized contracts on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner or any such officer as if it were the Partnership’s sole party in interest, both legally and beneficially. Each Partner hereby waives, to the fullest extent permitted by law, any and all defenses or other remedies that may be available to such Partner to contest, negate or disaffirm any action of the General Partner or any such officer in connection with any such dealing. In no event shall any Person dealing with the General Partner or any such officer or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or any such officer or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (b) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (c) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership.

If the Partnership is required to use a taxable period other than a year ending on December 31, the General Partner shall use reasonable efforts to change the taxable period of the Partnership to a year ending on

Notwithstanding any other provision herein contained, for the purposes of computing the adjustments under Section 743(b) of the Code, the General Partner shall be authorized (but not required) to adopt a convention whereby the price paid by a transferee of a Partnership Interest will be deemed to be the lowest quoted Closing Price of the Partnership Interests on any National Securities Exchange on which such Partnership Interests are listed or admitted to trading during the calendar month in which such transfer is deemed to occur pursuant to Section 6.2(g) without regard to the actual price paid by such transferee.

(b) Except as otherwise provided herein, the General Partner shall determine whether the Partnership should make any other elections permitted by the Code.

Section 9.3 Tax Controversies. Subject to the provisions hereof, the General Partner, or such other Partner as the General Partner shall designate, shall act as the Tax Matters Partner (as defined in the Code) and is authorized and required to represent the Partnership (at the Partnership’s expense) in connection with all examinations of the Partnership’s affairs by tax authorities, including resulting administrative and judicial proceedings, and to expend Partnership funds for professional services and costs associated therewith. Each Partner agrees to cooperate with the Tax Matters Partner and to do or refrain from doing any or all things reasonably required by the Tax Matters Partner to conduct such proceedings. Each Partner agrees that notice of or updates regarding tax controversies shall be deemed conclusively to have been given or made by the Tax Matters Partner if the Partnership has either (i) filed the information for which notice is required with the Commission via its Electronic Data Gathering, Analysis and Retrieval system and such information is publicly available on such system or (ii) made the information for which notice is required available on any publicly available website maintained by the Partnership, whether or not such Partner remains a Partner in the Partnership at the time such information is made publicly available.

(a) By acceptance of the transfer of any Limited Partner Interests or the issuance of any Limited Partner Interests in any case in accordance with this Agreement (including any Supplemental Terms Annex), and except

as provided in Section 4.8, each transferee or other recipient of a Limited Partner Interest (including any nominee holder or an agent or representative acquiring such Limited Partner Interests for the account of another Person) (i) shall be admitted to the Partnership as a Limited Partner with respect to the Limited Partner Interests so transferred or issued to such Person when any such transfer or issuance is reflected in the books and records of the Partnership, (ii) shall become bound by the terms of, and shall be deemed to have agreed to be bound by, this Agreement, (iii) shall become the Record Holder of the Limited Partner Interests so transferred or issued, (iv) represents that the transferee or other recipient has the capacity, power and authority to enter into this Agreement, and (v) makes the consents, acknowledgments and waivers contained in this Agreement, all with or without execution of this Agreement.

Except as otherwise provided in Section 4.5(f) or the terms of a Supplemental Terms Annex, a Person may become a Record Holder without the consent or approval of any of the Partners. A Person may not become a Limited Partner without acquiring a Limited Partner Interest. The rights and obligations of a Person who is an Ineligible Holder shall be determined in accordance with Section 4.8.

(b) The name and mailing address of each Record Holder shall be listed on the books and records of the Partnership maintained for such purpose by the General Partner or the Transfer Agent. The General Partner shall update its books and records from time to time as necessary to reflect accurately the information therein (or shall cause the Transfer Agent to do so, as applicable). A Limited Partner Interest may be represented by a Certificate, as provided in Section 4.1.

(c) Any transfer of a Limited Partner Interest shall not entitle the transferee to share in the profits and losses, to receive distributions, to receive allocations of income, gain, loss, deduction or credit or any similar item or to any other rights to which the transferor was entitled until the transferee becomes a Limited Partner pursuant to Section 10.1(a).

Section 10.2 Admission of Successor General Partner. A successor General Partner approved pursuant to Section 11.1 or the transferee of or successor to all of the General Partner Interest pursuant to Section 4.6 who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective immediately prior to the withdrawal of the predecessor or transferring General Partner, pursuant to Section 11.1 or the transfer of the General Partner Interest pursuant to Section 4.6, provided, however, that no such successor shall be admitted to the Partnership until compliance with the terms of Section 4.6 has occurred and such successor has executed and delivered such other documents or instruments as may be required to effect such admission. Any such successor shall, subject to the terms hereof, carry on the business of the members of the Partnership Group without dissolution.

Section 10.3 Amendment of Agreement and Certificate of Limited Partnership. To effect the admission to the Partnership of any Partner, the General Partner shall take all steps necessary under the Delaware Act to amend the records of the Partnership to reflect such admission and, if necessary, to prepare as soon as practicable an amendment to this Agreement and, if required by law, the General Partner shall prepare and file an amendment to the Certificate of Limited Partnership.

ARTICLE XI

WITHDRAWAL OF PARTNERS

Section 11.1 Withdrawal of the General Partner.

(a) The General Partner shall be deemed to have withdrawn from the Partnership upon the occurrence of any one of the following events (each such event herein referred to as an “Event of Withdrawal”):

(i) The General Partner transfers all of its rights as General Partner pursuant to Section 4.6;

(ii) The General Partner (A) makes a general assignment for the benefit of creditors; (B) files a voluntary bankruptcy petition for relief under Chapter 7 of the United States Bankruptcy Code; (C) files a petition or answer seeking for itself a liquidation, dissolution or similar relief (but not a reorganization) under any law; (D) files an answer or other pleading admitting or failing to contest the material allegations of a petition filed against the General Partner in a proceeding of the type described in clauses (A) through (C) of this Section 11.1(a)(ii); or (E) seeks, consents to or acquiesces in the appointment of a trustee (but not a debtor-in-possession), receiver or liquidator of the General Partner or of all or any substantial part of its properties;

(iii) A final and non-appealable order of relief under Chapter 7 of the United States Bankruptcy Code is entered by a court with appropriate jurisdiction pursuant to a voluntary or involuntary petition by or against the General Partner; or

(iv)(A) if the General Partner is a corporation, a certificate of dissolution or its equivalent is filed for the General Partner, or 90 days expire after the date of notice to the General Partner of revocation of its charter without a reinstatement of its charter, under the laws of its state of incorporation; (B) if the General Partner is a limited liability company or a partnership, the dissolution and commencement of winding up of the General Partner; (C) if the General Partner is acting in such capacity by virtue of being a trustee of a trust, the termination of the trust; and (D) if the General Partner is a natural person, his death or adjudication of incompetency.

If an Event of Withdrawal occurs, the withdrawing General Partner shall give notice to the Partners within 30 days after such occurrence. The Partners hereby agree that only the Events of Withdrawal described in this Section 11.1 shall result in the withdrawal of the General Partner from the Partnership.

(b) Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall not constitute a breach of this Agreement. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the General Partner as general partner or managing member, if any, to the extent applicable, of the other Group Members. If the General Partner gives notice of withdrawal pursuant to Section 11.1(a), the holders of a Unit Majority, may, prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If, prior to the effective date of the General Partner’s withdrawal, a successor is not selected by the Partners as provided herein, the Partnership shall be dissolved in accordance with Section 12.1, unless the business of the Partnership is continued pursuant to Section 12.2. Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.2.

Section 11.2 Interest of Departing General Partner and Successor General Partner.

(a) If the General Partner withdraws as General Partner (other than by transfer of its general partner interest), it shall become a Limited Partner and any economic general partner interest owned by it shall be converted into Common Units and, prior to the end of the Subordination Period, Subordinated Units with a value equivalent to the value of its general partner interest as agreed between the departing General Partner and the successor General Partner or, if they cannot agree or if there is no successor General Partner, pursuant to a valuation made by an investment banking firm or other independent expert, without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). For purposes of this Agreement, conversion of a general partner interest to Common Units and Subordination Units will be characterized as if the Departing General Partner (or its Affiliates) contributed the its general partner interest to the Partnership in exchange for the newly issued Common Units and Subordinated Units.

(b) If a successor General Partner is elected in accordance with the terms of Section 11.1 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former

General Partner), such successor General Partner shall be entitled to its Percentage Interest of all Partnership allocations and distributions to which the Departing General Partner was entitled, if any. In addition, the successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner’s admission, the successor General Partner’s interest in all Partnership distributions and allocations, if any, shall be its Percentage Interest.

Section 11.3 Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership; provided, however, that when a transferee of a Limited Partner’s Partnership Interest becomes a Record Holder of the Partnership Interest so transferred, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Partnership Interest so transferred.

ARTICLE XII

DISSOLUTION AND LIQUIDATION

Section 12.1 Dissolution. The Partnership shall not be dissolved by the admission of additional Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the withdrawal of the General Partner, if a successor General Partner is elected pursuant to Section 11.1, the Partnership shall not be dissolved and such successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and (subject to Section 12.2) its affairs shall be wound up, upon:

(a) an Event of Withdrawal of the General Partner as provided in Section 11.1(a) or a withdrawal of the General Partner in violation of this Agreement, unless a successor is elected and such successor is admitted to the Partnership pursuant to Section 10.2;

(b) an election to dissolve the Partnership by the General Partner that is approved by the holders of a Unit Majority;

(d) at any time there are no Limited Partners, unless the Partnership is continued without dissolution in accordance with the Delaware Act.

Section 12.2 Continuation of the Business of the Partnership After Dissolution. Upon (a) an Event of Withdrawal caused by the withdrawal of the General Partner as provided in Section 11.1(a)(iv) and (b) the failure of the Partners to select a successor to such Departing General Partner pursuant to Section 11.1 then, to the maximum extent permitted by law, within 180 days thereafter, a Unit Majority may elect to continue the business of the Partnership on the same terms and conditions set forth in this Agreement by appointing as the successor General Partner a Person approved by a Unit Majority. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then:

(i) the Partnership shall continue without dissolution unless earlier dissolved in accordance with this Article XII;

(ii) if the successor General Partner is not the former General Partner, then the interest of the former General Partner shall be treated in the manner provided in Section 11.2; and

(iii) the successor General Partner shall be admitted to the Partnership as General Partner, effective as of the Event of Withdrawal, by agreeing in writing to be bound by this Agreement;

provided, that the right of a Unit Majority to approve a successor General Partner and to continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of

Counsel that (x) the exercise of the right would not result in the loss of the limited liability of any Limited Partner under the Delaware Act and (y) neither the Partnership nor any successor limited partnership would be treated as an association taxable as a corporation or otherwise be taxable as an entity for U.S. federal income tax purposes upon the exercise of such right to continue (to the extent not already so treated or taxed).

Section 12.3 Liquidator. Upon dissolution of the Partnership, unless the business of the Partnership is continued pursuant to Section 12.2, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by holders of a Unit Majority. The Liquidator (if other than the General Partner) shall agree not to resign at any time without 15 days’ prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of a Unit Majority. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of a majority of the Outstanding Common Units. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XII, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 7.4) necessary or appropriate to carry out the duties and functions of the Liquidator hereunder for and during the period of time required to complete the winding up and liquidation of the Partnership as provided for herein.

Section 12.4 Liquidation. The Liquidator shall proceed to dispose of the assets of the Partnership, discharge its liabilities, and otherwise wind up its affairs in such manner and over such period as determined by the Liquidator, subject to Section 17-804 of the Delaware Act and the following:

(a) The assets may be disposed of by public or private sale or by distribution in kind to one or more Partners on such terms as the Liquidator and such Partner or Partners may agree. If any property is distributed in kind, the Partner receiving the property shall be deemed for purposes of Section 12.4(c) to have received cash equal to its fair market value; and contemporaneously therewith, appropriate cash distributions must be made to the other Partners. The Liquidator may defer liquidation or distribution of the Partnership’s assets for a reasonable time if it determines that an immediate sale or distribution of all or some of the Partnership’s assets would be impractical or would cause undue loss to the Partners. The Liquidator may distribute the Partnership’s assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Partners.

(b) Liabilities of the Partnership include amounts owed to the Liquidator as compensation for serving in such capacity (subject to the terms of Section 12.3) and amounts to Partners otherwise than in respect of their distribution rights under Article VI. With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional liquidation proceeds.

(c) Subject to the terms of any Supplemental Terms Annex, all property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 12.4(c)) for the taxable period of the Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable period (or, if later, within 90 days after said date of such occurrence).

Section 12.5 Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership cash and property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

Section 12.6 Return of Contributions. The General Partner shall not be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions of the Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from Partnership assets.

Section 12.7 Waiver of Partition. To the maximum extent permitted by law, each Partner hereby waives any right to partition of the Partnership property.

Section 12.8 Capital Account Restoration. No Limited Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. The General Partner shall be obligated to restore any negative balance in its Capital Account upon liquidation of its interest in the Partnership by the end of the taxable period of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation.

(k) a merger, conveyance or conversion pursuant to Section 14.3(d); or

An amendment shall be effective upon its approval by the General Partner and, except as otherwise provided by Sections 13.1 or 13.3, a Unit Majority, unless a greater or different percentage is required under this Agreement or by Delaware law. Each proposed amendment that requires the approval of the holders of a specified percentage of Outstanding Units shall be set forth in a writing that contains the text of the proposed amendment.

Section 13.3 Amendment Requirements.

(a) Notwithstanding the provisions of Section 13.1 (other than Section 13.1(d)(iv)) and Section 13.2, no provision of this Agreement (other than Section 13.5) that establishes a percentage of Outstanding Units (including Units deemed owned by the General Partner) or requires a vote or approval of Partners (or a subset of Partners) holding a specified Percentage Interest to take any action shall be amended, altered, changed, repealed

or rescinded in any respect that would have the effect of reducing or increasing such percentage, unless such amendment is approved by the written consent or the affirmative vote of holders of Outstanding Units whose aggregate Outstanding Units constitute not less than the voting requirement sought to be reduced or increased, as applicable, or the affirmative vote of Partners whose aggregate Percentage Interests constitute not less than the voting requirement sought to be reduced or increased, as applicable.

(b) Notwithstanding the provisions of Section 13.1 (other than Section 13.1(d)(iv)) and Section 13.2, no amendment to this Agreement may (i) enlarge the obligations of (including requiring any holder of a class of Partnership Interests to make additional Capital Contributions to the Partnership) any Limited Partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c), or (ii) enlarge the obligations of, restrict, change or modify in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which consent may be given or withheld at its option.

(c) Except as provided in Sections 13.1 or 14.3, any amendment that would have a material adverse effect on the rights or preferences of any class of Partnership Interests in relation to other classes of Partnership Interests must be approved by the holders of not less than a majority of the Outstanding Partnership Interests of the class affected. If the General Partner determines an amendment does not satisfy the requirements of Section 13.1(d)(i) because it adversely affects one or more classes of Partnership Interests, as compared to other classes of Partnership Interests, in any material respect, such amendment shall only be required to be approved by the adversely affected class or classes.

(d) Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 13.1 and except as otherwise provided by Section 14.3(b), no amendments shall become effective without the approval of the holders of at least 90% of the Percentage Interests of all Limited Partners voting as a single class unless the Partnership obtains an Opinion of Counsel to the effect that such amendment will not affect the limited liability of any Limited Partner under applicable partnership law of the state under whose laws the Partnership is organized.

(e) Except as provided in Section 13.1, this Section 13.3 shall only be amended with the approval of Partners (including the General Partner and its Affiliates) holding at least 90% of the Percentage Interests of all Limited Partners.

Section 13.4 Amendments to Organizational Documents of General Partner and Other Subsidiaries. Each Partner agrees that the General Partner, without the approval of any other Partner, may amend any provision of the organizational documents of any direct or indirect subsidiary of the Partnership (including the General Partner and the Original General Partner) and execute, swear to, acknowledge, deliver, file and record whatever documents may be required in connection therewith.

Section 13.5 Special Meetings; Annual Meetings; Election of Directors.

(a) Subject to the terms of a Supplemental Terms Annex, all acts of Limited Partners to be taken pursuant to this Agreement shall be taken in the manner provided in this Article XIII. Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Units of the class or classes for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the specific purposes for which the special meeting is to be called and the class or classes of Units for which the meeting is proposed. No business may be brought by any Limited Partner before such special meeting except the business listed in the related request. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the

meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the time notice of the meeting is given as provided in Section 16.1. Limited Partners shall not vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

(b) (i) Directors shall be elected by the Limited Partners in accordance with this Section 13.5. An annual meeting of the Limited Partners for the election of Directors to the Board of Directors of the General Partner and such other matters as the Board of Directors shall submit to a vote of the Limited Partners shall be held at such date and time as may be fixed from time to time by the General Partner at such place within or without the State of Delaware as may be fixed from time to time by the General Partner and all as stated in the notice of the meeting. Notice of the annual meeting shall be given in accordance with Section 13.6 not less than 10 days nor more than 60 days prior to the date of such meeting. The first such annual meeting of the Limited Partners for the election of Directors to the Board of Directors of the General Partner shall take place prior to May 31, 2016.

(ii) The Limited Partners entitled to vote at the annual meeting shall vote together as a single class. The Limited Partners entitled to vote shall elect by a plurality of the votes cast at such meeting persons to serve on the Board of Directors of the General Partner who are nominated in accordance with the provisions of this Section 13.5(b). The exercise by a Limited Partner of the right to elect the Directors and any other rights afforded to such Limited Partner under this Section 13.5(b) shall be in such Limited Partner’s capacity as a limited partner of the Partnership and shall not cause a Limited Partner to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize such Limited Partner’s limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

(iii) Solely with respect to the election of Directors to the Board of Directors, the General Partner and the Partnership shall not be entitled to vote Units that are otherwise entitled to vote at any meeting of the Limited Partners and the foregoing Units shall not be counted when calculating the required votes for such matter and shall not be deemed to be Outstanding for purposes of determining a quorum for such meeting pursuant to Section 13.10 (but such Units shall not, however, be treated as a separate class of Partnership Interests for purposes of this Agreement).

(iv) At all elections of the Board of Directors, each Limited Partner entitled to vote at such an election will be entitled to cumulate his votes and give one candidate, or divide among any number of candidates, a number of votes equal to the product of (x) the number of Units held by such Limited Partner entitled to vote for the election of Board Members, multiplied by (y) the number of Board Members to be elected at such meeting by the Limited Partners.

(v) The number of Directors that shall constitute the whole Board of Directors of the General Partner shall not be less than nine and not more than thirteen as shall be established from time to time by a resolution adopted by a majority of the Directors, provided that no decrease shall shorten the term of any incumbent Director. At each annual meeting of the Limited Partners, Directors to replace those whose terms expire at such annual meeting shall be elected to hold office until the next succeeding annual meeting.

(vi) Each Director shall hold office for the term for which such Director is elected and thereafter until such Director’s successor shall have been duly elected and qualified, or until such Director’s earlier death, resignation or removal. Any vacancies may be filled, until the next annual meeting at which the term of such class expires, by a majority of the remaining Directors then in office. Each Director may, during his or her term of office, be removed at any time, with or without Cause, by the written consent of the holders of record of a Cumulative Majority of the Common Units and Subordinated Units then Outstanding, and any vacancy created by such removal may also be filled by the holders of record of a Cumulative Majority of the Common Units and Subordinated Units then Outstanding pursuant to a written consent or at the next annual or special meeting of Limited Partners. “Cause” means a court of competent jurisdiction has entered a final,

non-appealable judgment finding the Director liable to the Partnership or any Limited Partner for actual fraud or willful misconduct in his or her capacity as a Director.

(vii) Nominations of persons for election to the Board of Directors of the General Partner may be made at an annual meeting of the Limited Partners or, provided that the Board of Directors or Limited Partners have determined that Directors shall be elected at such a meeting, a special meeting of the Limited Partners, in any such case only pursuant to the General Partner’s notice of meeting (or any supplement thereto), (a) by or at the direction of the Board of Directors or any committee thereof or (b) if such nominee is a Qualified Nominee, by any Limited Partner or group of Limited Partners (either, a “Nominating Limited Partner Group”) who (x) together hold Units representing at least ten percent (10%) of the Fully Diluted Percentage Interests both at the time of giving of notice of such nominations and at the time of the meeting, (y) are each entitled to vote for the election of the class of Director so nominated and (z) comply with the notice procedures set forth in Section 13.5(b)(viii). No Limited Partner may participate in more than one Nominating Limited Partner Group nominating Directors for election at any annual or special meeting. Nominations by Limited Partners of any individuals for election to the Board shall be made pursuant to timely notice in writing and in proper form (the “Nomination Notice”) to the General Partner. Any Nomination Notice shall include information about the Nominating Limited Partner Group and the individuals nominated by such Nominating Limited Partner Group for election to the Board as may reasonably be requested by the Board in policies or procedures delivered to the Limited Partners not less than thirty (30) days prior to the commencement of the Nomination Period. For each election, each Nominating Limited Partner Group may nominate for election to the Board of Directors a number of individuals equal to the number of Directors to be elected at such annual or special meeting. Any Director that has been removed by the Board in accordance with Section 13.5(b)(x) is not eligible to be a Qualified Nominee nominated by any Nominating Limited Partner Group until such time as the Board determines that his or her service on the Board would no longer be detrimental to the interests of the Company or the Partnership.

(viii) (A) For any nominations brought before an annual meeting by a Nominating Limited Partner Group pursuant to Section 13.5(b)(vii), such Nominating Limited Partner must have given timely notice thereof in writing to the General Partner. To be timely, such notice shall be delivered to the General Partner not later than the close of business on the ninetieth (90th) day, nor earlier than the close of business on the one hundred twentieth (120th) day, prior to the first anniversary of the preceding year’s annual meeting or, in the case of the first annual meeting, prior to May 31, 2016 (provided, however, that in the event that the date of the annual meeting is more than thirty (30) days before or more than seventy (70) days after such anniversary date, such Nomination Notice must be so delivered not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Partnership or the General Partner)(such period, the “Nomination Period”). In no event shall the public announcement of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a Nomination Notice as described above. Such Nominating Limited Partner Group’s Nomination Notice shall set forth: (a) as to each person whom the Nominating Limited Partner Group proposes to nominate for election as a Director (i) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to and in accordance with Regulation 14A under the Securities Exchange Act and (ii) such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected; and (b) as to the Nominating Limited Partner Group giving such Nomination Notice and the beneficial owner, if any, on whose behalf the nomination is made (i) the name and address of each Limited Partner in the Nominating Limited Partner Group, as they appear on the Partnership’s books and records, and of such beneficial owner, (ii) the class or series and number of Units which are owned beneficially and of record by each such Limited Partner and such beneficial owner, (iii) a description of any agreement, arrangement or understanding with respect to the nomination between or among each such Limited Partner and such

beneficial owner, any of their respective Affiliates or associates, and any others acting in concert with any of the foregoing, (iv) a description of any agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, warrants, stock appreciation or similar rights, hedging transactions, and borrowed or loaned Units) that has been entered into as of the date of such Nomination Notice by, or on behalf of, each such Limited Partner and such beneficial owners, the effect or intent of which is to mitigate loss to, manage risk or benefit of Unit price changes for, or increase or decrease the voting power of, each such Limited Partner and such beneficial owner, with respect to Units, (v) a representation that each such Limited Partner is a Record Holder entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such nomination, and (vi) a representation whether each such Limited Partner or the beneficial owner, if any, intends or is part of a group which intends (a) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Partnership’s Outstanding Units required to elect the nominee and/or (b) otherwise to solicit proxies from Limited Partners in support of such nomination. The General Partner may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a Director of the General Partner.

(B) Notwithstanding anything in the second sentence of Section 13.5(b)(viii)(A) to the contrary, in the event that the number of Directors to be elected to the Board of Directors of the General Partner is increased effective at the annual meeting and there is no public announcement by the Partnership or the General Partner naming the nominees for the additional directorships at least one hundred (100) days prior to the first anniversary of the preceding year’s annual meeting or, in the case of the first annual meeting, prior to May 31, 2016, Nomination Notice shall also be considered timely, but only with respect to nominees for the additional directorships, if it shall be delivered to the General Partner not later than the close of business on the tenth (10th) day following the day on which such public announcement is first made by the Partnership or the General Partner.

(C) In the event the General Partner calls a special meeting of Limited Partners for the purpose of electing one or more Directors to the Board of Directors, any Nomination Notice shall be delivered to the General Partner not earlier than the close of business on the one hundred twentieth (120th) day prior to such special meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such special meeting or the tenth (10th) day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a new time period (or extend any time period) for the giving of a Nomination Notice as described above.

(D) (1) Only such persons who are nominated in accordance with the procedures set forth in this Section 13.5(b) shall be eligible to be elected at an annual or special meeting of Limited Partners to serve as Directors. Except as otherwise provided by law, the chairman designated by the General Partner pursuant to Section 13.11 shall have the power and duty (a) to determine whether a nomination was made in accordance with the procedures set forth in this Section 13.5(b) and (b) if any proposed nomination was not made in compliance with this Section 13.5(b), to declare that such nomination shall be disregarded. Notwithstanding the foregoing provisions of this Section 13.5(b), unless otherwise required by law, if the Limited Partner (or a qualified representative of the Limited Partner) does not appear at the annual or special meeting of Limited Partners to present a nomination, such nomination shall be disregarded notwithstanding that proxies in respect of such vote may have been received by the General Partner or the Partnership. For purposes of this Section 13.5(b)(viii), to be considered a qualified representative of the Limited Partner, a person must be a duly authorized officer, manager or partner of such Limited Partner or must be authorized by a writing executed by such Limited Partner or an electronic transmission delivered by such Limited Partner to act for such Limited Partner as proxy at the meeting of Limited Partners and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of Limited Partners.

(2) For purposes of this Section 13.5(b)(vi), “public announcement” shall include disclosure in a press release reported by the Dow Jones News Service, Associated Press or other national news service or in a document publicly filed by the Partnership or the General Partner with the Commission pursuant to Section 13, 14 or 15(d) of the Securities Exchange Act.

(3) Notwithstanding the foregoing provisions of this Section 13.5(b), a Limited Partner shall also comply with all applicable requirements of the Securities Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 13.5(b); provided however, that any references in this Agreement to the Securities Exchange Act or the rules promulgated thereunder are not intended to and shall not limit any requirements applicable to nominations pursuant to this Section 13.5(b), and compliance with this Section 13.5(b) shall be the exclusive means for a Limited Partner to make nominations.

(ix) Notwithstanding any other provision of this Section 13.5(b), the General Partner and the members of the General Partner are authorized, and shall use their commercially reasonable best efforts, to take such action (including, without limitation, the removal and appointment of Directors) as shall be necessary or appropriate to cause a majority of the Board of Directors of the General Partner to consist of individuals other than individuals who are officers, directors, employees or agents of the General Partner; provided, however, that this provision shall not preclude the election of individuals who are Directors of the General Partner and who are not otherwise affiliated with the General Partner; provided further, however, that this provision shall be subject to the compliance with any rule or listing standard of a National Securities Exchange on which any Units or other Partnership Interests are listed or quoted.

(x) In the event that the Board of Directors determines, by a Supermajority Vote of the Board of Directors, that the service of any Director is detrimental to the interests of the General Partner or the Partnership, including because such Board member or any of his or her controlled Affiliates is actively engaged in a business or activity (as opposed to passive investments) which is detrimentally competitive in any material respect with the business of the General Partner or the Partnership or any of their respective controlled Affiliates, the Board of Directors may remove such Director by Supermajority Vote of the Board of Directors and any vacancy created by such removal shall be filled by the Limited Partners (voting in accordance with the cumulative voting provisions set forth in Section 13.5(b)(iv)) entitled to elect such Director by written consent or at the next annual or special meeting of Limited Partners.

(xi) This Section 13.5(b) shall not be deemed in any way to limit or impair the ability of the Board of Directors of the General Partner to adopt a “poison pill” or Unitholder or other similar rights plan with respect to the Partnership, whether such poison pill or plan contains “dead hand” provisions, “no hand” provisions or other provisions relating to the redemption of the poison pill or plan, in each case as such terms are used under Delaware common law.

(xii) The General Partner shall use its commercially reasonable best efforts to take such action as shall be necessary or appropriate to give effect to and implement the provisions of this Section 13.5(b), including, without limitation, amending the limited liability company agreement of the General Partner.

(xiii) Except as set forth in Section 13.5(b)(iii), this Section 13.5(b) may not be amended except upon the prior approval of Limited Partners that hold two-thirds of the Outstanding Common Units and Subordinated Units, voting as a single class.

(c) If the General Partner delegates to an existing or newly formed wholly-owned subsidiary the power and authority to manage and control the business and affairs of the Partnership Group, the provisions of Section 13.5(b) shall be applicable with respect to the board of directors or other governing body of such subsidiary.

Section 13.6 Notice of a Meeting. Notice of a meeting called pursuant to Section 13.5 shall be given to the Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1. The notice shall be deemed to have been given at the time when deposited in the mail or sent by other means of written communication.

Section 13.7 Record Date. For purposes of determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.12 the General Partner may set a Record Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading or U.S. federal securities laws, in which case the rule, regulation, guideline or requirement of such National Securities Exchange or U.S. federal securities laws shall govern) or (b) in the event that approvals are sought without a meeting, the date by which Limited Partners are requested in writing by the General Partner to give such approvals. If the General Partner does not set a Record Date, then (a) the Record Date for determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners shall be the close of business on the day next preceding the day on which notice is given, and (b) the Record Date for determining the Limited Partners entitled to give approvals without a meeting shall be the date the first written approval is deposited with the Partnership in care of the General Partner in accordance with Section 13.12.

Section 13.8 Adjournment. Prior to the date upon which any meeting of Limited Partners is to be held, the General Partner may postpone such meeting one or more times for any reason by giving notice to each Limited Partner entitled to vote at the meeting so postponed of the place, date and hour at which such meeting would be held. Such notice shall be given not fewer than two days before the date of such meeting and otherwise in accordance with this Article XIII. When a meeting is postponed, a new Record Date need not be fixed unless such postponement shall be for more than 45 days. Any meeting of Limited Partners may be adjourned by the General Partner one or more times for any reason, including the failure of a quorum to be present at the meeting with respect to any proposal or the failure of any proposal to receive sufficient votes for approval. No Limited Partner vote shall be required for any adjournment. A meeting of Limited Partners may be adjourned by the General Partner as to one or more proposals regardless of whether action has been taken on other matters. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at which the adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII.

Section 13.9 Waiver of Notice; Approval of Meeting; Approval of Minutes. The transaction of business at any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at the meeting.

Section 13.10 Quorum and Voting. The holders of a majority, by Percentage Interest, of Partnership Interests of the class or classes for which a meeting has been called (including Partnership Interests deemed owned by the General Partner) represented in person or by proxy shall constitute a quorum at a meeting of Partners of such class or classes unless any such action by the Partners requires approval by holders of a greater Percentage Interest, in which case the quorum shall be such greater Percentage Interest. Abstentions and broker non-votes in respect of such Units shall be deemed to be Units present at such meeting for purposes of establishing a quorum. For all matters presented to the Limited Partners holding Outstanding Units at a meeting at which a quorum is present for which no minimum or other vote of Limited Partners is required by any other provision of this Agreement, the rules or regulations of any National Securities Exchange on which the Common Units are admitted to trading, or applicable law or pursuant to any regulation applicable to the Partnership or its Partnership Interests, a majority of the votes cast by the Limited Partners holding Outstanding Units shall be deemed to constitute the act of all Limited Partners (with abstentions and broker non-votes being deemed to not have been cast with respect to such matter). On any matter where a minimum or other vote of Limited Partners

holding Outstanding Units is provided by any other provision of this Agreement or required by the rules or regulations of any National Securities Exchange on which the Common Units are admitted to trading, or applicable law or pursuant to any regulation applicable to the Partnership or its Partnership Interests, such minimum or other vote shall be the vote of Limited Partners required to approve such matter (with the effect of abstentions and broker non-votes to be determined based on the vote of Limited Partners required to approve such matter; provided that if the effect of abstentions and broker non-votes is not specified by such applicable rule, regulation or law, and there is no prevailing interpretation of such effect, then abstentions and broker non-votes shall be deemed to not have been cast with respect to such matter; provided further, that, for the avoidance of doubt, with respect to any matter on which this Agreement requires the approval of a specified percentage of the Outstanding Units, abstentions and broker non-votes shall be counted as votes against such matter). The Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by holders of the required Percentage Interest specified in this Agreement.

Section 13.11 Conduct of a Meeting. The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including the determination of Persons entitled to vote, the existence of a quorum, the satisfaction of the requirements of Section 13.5, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or during the meeting or voting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting. All minutes shall be kept with the records of the Partnership maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of approvals in writing, including regulations in regard to the appointment of proxies, the appointment and duties of inspectors of votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the revocation of approvals in writing.

Section 13.12 Action Without a Meeting. If authorized by the General Partner, any action that may be taken at a meeting of the Limited Partners may be taken without a meeting, without a vote and without prior notice, if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage, by Percentage Interest, of the Partnership Interests of the class or classes for which a meeting has been called (including Partnership Interests deemed owned by the General Partner), as the case may be, that would be necessary to authorize or take such action at a meeting at which all the Limited Partners entitled to vote at such meeting were present and voted (unless such provision conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern). Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Units held by the Limited Partners, the Partnership shall be deemed to have failed to receive a ballot for the Units that were not voted. If approval of the taking of any action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) they are deposited with the Partnership in care of the General Partner and (b) an Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners. Nothing contained in this Section 13.12 shall be deemed to require the General Partner to solicit all Limited Partners in connection with a matter approved by the holders of the requisite percentage of Units acting by written consent without a meeting.

Section 13.13 Right to Vote and Related Matters.

(a) Only those Record Holders of the Outstanding Units on the Record Date set pursuant to Section 13.7 shall be entitled to notice of, and to vote at, a meeting of Limited Partners or to act with respect to matters as to which the holders of the Outstanding Units have the right to vote or to act. All references in this Agreement to votes of, or other acts that may be taken by, the Outstanding Units shall be deemed to be references to the votes or acts of the Record Holders of such Outstanding Units.

(b) With respect to Units that are held for a Person’s account by another Person (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), in whose name such Units are registered, such other Person shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such Persons provides otherwise, vote such Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume it is so acting without further inquiry. The provisions of this Section 13.13(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3.

(viii) such other provisions with respect to the proposed conversion that the General Partner determines to be necessary or appropriate.

Section 14.3 Approval by Partners of Merger or Consolidation.

(a) Except as provided in Sections 14.3(d) and 14.3(e) and subject to the terms of any Supplemental Terms Annex, the General Partner, upon its approval of the Merger Agreement or Plan of Conversion, as the case may be, shall direct that the Merger Agreement or Plan of Conversion, as applicable, be submitted to a vote of Partners, whether at a special meeting or by written consent, in either case in accordance with the requirements of Article XIII.

(b) Except as provided in Sections 14.3(d) and 14.3(e), the Merger Agreement or Plan of Conversion shall be approved upon receiving the affirmative vote or consent of the holders of a Unit Majority unless the Merger

Agreement or Plan of Conversion provides for an amendment to any provision of this Agreement that, if contained in an amendment to this Agreement adopted pursuant to Article XIII, would require for its approval the vote or consent of a greater percentage of the Outstanding Units or of any class of Limited Partners, in which case such greater percentage vote or consent shall be required for approval of the Merger Agreement or Plan of Conversion.

(c) Except as provided in Sections 14.3(d) and 14.3(e), after such approval by vote or consent of the Limited Partners, and at any time prior to the filing of the certificate of merger or certificate of conversion pursuant to Section 14.4, the merger, consolidation or conversion may be abandoned pursuant to provisions therefor, if any, set forth in the Merger Agreement or Plan of Conversion.

(d) Notwithstanding anything else contained in this Article XIV or in this Agreement but subject to the terms of any Supplemental Terms Annex, the General Partner is permitted, without Limited Partner approval, to convert the Partnership or any Group Member into a new limited liability entity, to merge the Partnership or any Group Member into, or convey all of the Partnership’s assets to, another limited liability entity that shall be newly formed and shall have no assets, liabilities or operations at the time of such merger or conveyance other than those it receives from the Partnership or other Group Member if (i) the General Partner has received an Opinion of Counsel that the conversion, merger or conveyance, as the case may be, would not result in the loss of the limited liability of any Limited Partner or any Group Member under the Delaware Act or cause the Partnership or any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already treated as such), (ii) the sole purpose of such conversion, merger or conveyance is to effect a mere change in the legal form of the Partnership into another limited liability entity and (iii) the General Partner determines that the governing instruments of the new entity provide the Limited Partners and the General Partner with substantially the same rights and obligations as are contained in this Agreement.

(e) Additionally, notwithstanding anything else contained in this Article XIV or in this Agreement but subject to the terms of any Supplemental Terms Annex, the General Partner is permitted, without Limited Partner approval, to merge or consolidate the Partnership with or into another entity if (A) the General Partner has received an Opinion of Counsel that the merger or consolidation, as the case may be, would not result in the loss of the limited liability under the Delaware Act of any Limited Partner or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already treated as such), (B) the merger or consolidation would not result in an amendment to this Agreement, other than any amendments that could be adopted pursuant to Section 13.1, (C) the Partnership is the Surviving Business Entity in such merger or consolidation, (D) each Partnership Interest outstanding immediately prior to the effective date of the merger or consolidation is to be an identical Partnership Interest of the Partnership after the effective date of the merger or consolidation, and (E) the number of Partnership Interests to be issued by the Partnership in such merger or consolidation does not exceed 20% of the Partnership Interests Outstanding immediately prior to the effective date of such merger or consolidation.

Section 14.4 Certificate of Merger or Conversion.

RIGHT TO ACQUIRE LIMITED PARTNER INTERESTS

Section 15.1 Right to Acquire Limited Partner Interests.

(a) Subject to the provisions of any Preferred Terms Annex, notwithstanding any other provision of this Agreement, if at any time during the Subordination Period, the Partnership, together with any of its Affiliates, holds in the aggregate more than 80% of the maximum number of Common Units that were Outstanding at any point in time, the Partnership shall then have the right, which right it may assign and transfer in whole or in part to any Affiliate, exercisable in its sole discretion, to purchase all, but not less than all, of the Outstanding Common Units, at the greater of (x) the Current Market Price as of the date three days prior to the date that the notice described in Section 15.1(b) is mailed and (y) the highest price paid by the Partnership for any Common Units purchased during the 90-day period preceding the date that the notice described in Section 15.1(b) is mailed.

(b) If the Partnership or its Affiliate elects to exercise the right to purchase Common Units granted pursuant to Section 15.1(a), then the Partnership shall deliver to the Transfer Agent notice of such election to purchase (the “Notice of Election to Purchase”) and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the Record Holders of Common Units of such class (as of a Record Date selected by the Partnership) at least 10, but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be filed and distributed as may be required by the Commission or any National Securities Exchange on which such Common Units are listed. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 15.1(a)) at which Common Units will be purchased and state that the Partnership or its Affiliate, as the case may be, elects to purchase such Common Units, upon surrender of Certificates representing such Common Units in the case of Common Units evidenced by Certificates, in exchange for payment, at such office or offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which such Common Units are listed or admitted to trading. Any such Notice of Election to Purchase mailed to a Record Holder of Common Units at his address as reflected in the records of the Transfer Agent shall be conclusively presumed to have been given

regardless of whether the owner receives such notice. On or prior to the Purchase Date, the Partnership or its Affiliate, as the case may be, shall deposit with the Transfer Agent cash in an amount sufficient to pay the aggregate purchase price of all of such Common Units to be purchased in accordance with this Section 15.1. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 10 days prior to the Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Common Units subject to purchase as provided herein, then from and after the Purchase Date, notwithstanding that any Certificate shall not have been surrendered for purchase, all rights of the holders of such Common Units shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Common Units therefor, without interest, upon surrender to the Transfer Agent of the Certificates representing such Common Units in the case of Common Units evidenced by Certificates, and such Common Units shall thereupon be deemed to be transferred to the Partnership or its Affiliate, as the case may be, on the record books of the Transfer Agent and the Partnership, and the Partnership or its Affiliate, as the case may be, shall be deemed to be the owner of all such Common Units from and after the Purchase Date and shall have all rights as the owner of such Common Units.

(c) In the case of Common Units evidenced by Certificates, at any time from and after the Purchase Date, a holder of an Outstanding Common Unit subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Common Unit to the Transfer Agent in exchange for payment of the amount described in Section 15.1(a), therefor, without interest thereon.

Notwithstanding the other provisions of the Partnership Agreement or this Annex, without first obtaining a Series A Majority Approval, the General Partner shall not, and shall not cause the Partnership to, either directly or indirectly, by amendment, merger, consolidation or otherwise, effect any split, reverse split, subdivision, combination or similar action with respect to the Series A Preferred Units.

Annex A-8

iv.

amend, modify or waive the provisions of this Paragraph 4(d)(iv).

Any of the rights, powers or preferences of the Series A Preferred Unitholders set forth herein may be waived in writing by any Series A Preferred Unitholder with respect to such holder.

5.	Optional Conversion.

Each Series A Preferred Unit may be converted, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into Common Units and, prior to the end of the Subordination Period, Subordinated Units at the then effective applicable Conversion Rates. Each Series A Preferred Unit shall have an initial Conversion Price of $14.2683 in respect of the Common Units and $14.2683 in respect of the Subordinated Units (as adjusted as provided herein, the “Conversion Prices”) and an initial Conversion Rate of 30.3431:1 in respect of the Common Units and 39.7427:1 in respect of the Subordinated Units per Series A Preferred Unit, each subject to adjustment as provided herein.

The Conversion Prices and the Conversion Rates for the Series A Preferred Units, each of which is subject to adjustment as provided herein, shall be set forth in one or more written statements signed by the General Partner and maintained at the principal office of the Partnership.

In order to exercise the conversion privilege, the holder of any Series A Preferred Units to be converted shall give written notice (the “Conversion Notice”) to the Partnership that the holder elects to convert all or a specified number of Series A Preferred Units held. A Conversion Notice may be given at any time but shall only be effective as of the Conversion Date.

Upon any such conversion, no adjustment to the Conversion Rate shall be made for Unpaid Series A Preferred Yield on the Series A Preferred Units surrendered for conversion or any unpaid distributions on the Common Units or Subordinated Units delivered pursuant thereto. The Series A Preferred Unitholder shall remain entitled to receive his Unpaid Series A Preferred Yield accrued through the date prior to the Conversion Date, the Partnership shall pay such amount to such holder promptly following receipt of the Conversion Notice, and any such payment shall be treated as a distribution to such Series A Preferred Unitholder for purposes of maintaining Capital Accounts. Upon each conversion, the Partnership shall make a cash payment to the converting Series A Preferred Unitholder, and the converting Series A Preferred Unitholder shall make a cash payment to the Partnership, to adjust for any distributions declared in respect of the Common Units, the Subordinated Units or the Series A Preferred Units on or after the Conversion Date but prior to the receipt of the Conversion Notice, the intent being to put both the converting Series A Preferred Unitholder and the Partnership in the same position that they would have been if the Conversion Notice had been delivered on or before the Conversion Date. Any cash payment made pursuant to the preceding sentence shall be treated as

Annex A-9

(i) a distribution to the Series A Preferred Unitholder if made by the Partnership and (ii) a Capital Contribution if made by the Series A Preferred Unitholder.

The Partnership shall not issue fractions of Common Units or Subordinated Units upon conversion of Series A Preferred Units or scrip in lieu thereof. If any fraction of a Common Unit or Subordinated Unit would, except for the provisions of this Paragraph 5(e), be issuable upon conversion of any Series A Preferred Unit, the Partnership shall in lieu thereof pay to the Person entitled thereto an amount in cash equal to the current value of such fraction, calculated to the nearest one-hundredth (1/100) of a Common Unit or Subordinated Unit, to be computed on the basis of the Interest Fair Market Value of one Common Unit or Subordinated Unit as determined by the General Partner; provided, however, that if the amount payable in respect of any fractional Common Unit or Subordinated Unit would not exceed $10.00, the Partnership may at its option round the number of Common Units or Subordinated Units to be issued in respect of the conversion of Series A Preferred Units to the nearest whole number, with 0.50 Common Unit or Subordinated Unit being rounded up to one Common Unit or Subordinated Unit. As soon as practicable after the effectiveness of any conversion, the Partnership shall cause to be issued and delivered to the converting holder any cash in lieu of a fraction of a Common Unit or Subordinated Unit otherwise issuable upon such conversion. For purposes of determining fractional units, all Common Units or Subordinated Units or fractions thereof being issued to a holder upon conversion as of a particular Conversion Date shall be aggregated so that, under no circumstances, would any particular conversion by a holder result in more than one fractional Common Unit or Subordinated Unit.

The Series A Preferred Units shall cease to be convertible on the day of the first liquidating distribution pursuant to Paragraph 13.

Each Series A Preferred Unit which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding as of the Conversion Date and all rights with respect to such Series A Preferred Unit shall terminate, except only the rights of the holder thereof to receive Common Units and Subordinated Units in exchange therefor (and any payment in lieu of a fractional Common Unit and/or Subordinated Unit pursuant to Paragraph 5(e)) and payment of any Unpaid Series A Preferred Yield thereon.

In the event of an inaccuracy in or breach of the representations and warranties in Section 3.3(a) of the Securities Purchase Agreement, determined without regard to any knowledge qualifiers, the sole and exclusive remedies therefor shall be (i) the recalculation and adjustment of the Conversion Price to what it would have been if there had been no such breach, recalculating such Conversion Price as equal to the lesser of (1) the initial Conversion Price of $14.2683 in respect of the Common Units and $14.2683 in respect of the Subordinated Units, or (2) the quotient obtained by dividing (A) the Value determined immediately before the issuance of the Original LP Series A Preferred Units pursuant to the Securities Purchase Agreement by (B) the total number of Original LP Common Units outstanding on the date of issuance of such Original LP Series A Preferred Units (assuming (x) the conversion of the then issued and outstanding Original LP Series A Preferred Units into Original LP Common Units at the then applicable conversion rate and (y) any issued and outstanding Original LP Common Units held by members of the board of directors or officers or employees of the Original Partnership, the Original General Partner or any subsidiary of the Original Partnership or the Original General Partner are outstanding even if subject to forfeiture), (ii) the issuance by the Original Partnership of any additional Original LP Common Units that would have been issued by the Original Partnership upon conversion of Original LP Series A Preferred Units, if necessary, and (iii) the payment of any additional distributions that would have been paid by the Original Partnership, the Original General Partner, the Partnership or the Company, if necessary, in the case of each of clauses (i) through (iii) above as if the initial Conversion Price had been correctly determined.

6.	Mandatory Conversion

Effective as of each Mandatory Conversion Date, there shall automatically be converted into Subordinated Units and Common Units at the then effective Conversion Rates a number of Series A

Annex A-10

Preferred Units held by each Series A Preferred Unitholder (after the provisions of Paragraphs 8(a) and 8(e) are applied with respect to the Scheduled Redemption Date immediately preceding such Mandatory Conversion Date) equal to the amount, if any, by which the applicable Minimum Conversion/Redemption Amount exceeds the number of Series A Preferred Units which, while held by such Series A Preferred Unitholder, were previously redeemed or converted into Subordinated Units or Common Units. If a Series A Preferred Unitholder Disposes of any Series A Preferred Units which are subject to conversion pursuant to this Paragraph 6 on or after the Mandatory Conversion Date and on or before the later of the Annual Redemption/Conversion Deadline or 10 days after the Partnership’s receipt from such Series A Preferred Unitholder of a Holder Redemption Notice pursuant to Paragraph 8(a), such Series A Preferred Units so Disposed shall, in the hands of the transferee, be subject to conversion pursuant to this Paragraph 6.

Effective as of each Mandatory Conversion Date, any Series A Preferred Unit so converted shall no longer be deemed to be outstanding and all rights with respect to each Series A Preferred Unit so converted shall terminate, except only the rights of the holder thereof to receive the number of Subordinated Units and Common Units into which such Series A Preferred Unit has been converted (and any payment in lieu of a fractional Subordinated Unit and Common Unit pursuant to Paragraph 5(e)) and payment of any Unpaid Series A Preferred Yield thereon, which the Partnership shall pay to the holder promptly following the implementation of mandatory conversion pursuant to Paragraph 6, and any such payment shall for purposes of this Annex A be treated as a distribution to such Series A Preferred Unitholder for purposes of maintaining Capital Accounts. Upon each conversion, the Partnership shall make a cash payment to the converting Series A Preferred Unitholder, and the converting Series A Preferred Unitholder shall make a cash payment to the Partnership, to adjust for any distributions declared in respect of the Subordinated Units, Common Units or the Series A Preferred Units on or after the Conversion Date but prior to the implementation of mandatory conversion pursuant to Paragraph 6, the intent being to put both the converting Series A Preferred Unitholder and the Partnership in the same position that they would have been if the mandatory conversion pursuant to Paragraph 6 had been implemented on the Mandatory Conversion Date. Any cash payment made pursuant to the preceding sentence shall be treated as (i) a distribution to the Series A Preferred Unitholder if made by the Partnership and (ii) a Capital Contribution if made by the Series A Preferred Unitholder.

7.	Anti-Dilution Provisions

The Conversion Prices and the Conversion Rates shall be subject to adjustment from time to time in accordance with this Paragraph 7.

In case the Partnership shall at any time (i) subdivide the outstanding Subordinated Units or Common Units, (ii) make a distribution on its outstanding Subordinated Units or Common Units payable in the same type of Units or (iii) combine its outstanding Series A Preferred Units, the Conversion Price with respect to the Subordinated Units or Common Units, as applicable in effect immediately prior to such subdivision or distribution shall be proportionately decreased (with appropriate adjustments to the applicable Conversion Rate in effect immediately prior to such subdivision or distribution). In case the Partnership shall at any time (i) combine its outstanding Subordinated Units or Common Units, (ii) subdivide the outstanding Series A Preferred Units or (iii) make a distribution on its outstanding Series A Preferred Units payable in Series A Preferred Units, the Conversion Price in effect with respect to the Subordinated Units or Common Units, as applicable immediately prior to such combination shall be proportionately increased (with appropriate adjustments to the applicable Conversion Rate in effect immediately prior to such combination).

If any capital reorganization or reclassification of the Units of the Partnership or consolidation or merger of the Partnership with another Entity shall be effected in such a way that Subordinated Unitholders or Common Unitholders shall be entitled to receive stock, securities, cash or other property with respect to or in exchange for Subordinated Units or Common Units, then, as a condition of such reorganization, reclassification, consolidation or merger, lawful and adequate provision shall be made

Annex A-11

whereby the Series A Preferred Unitholders shall have the right to acquire and receive upon conversion of the Series A Preferred Units, such shares of stock, securities, cash or other property issuable or payable (as part of the reorganization, reclassification, consolidation, merger or sale) with respect to or in exchange for such number of outstanding Subordinated Units or Common Units as would have been received upon conversion of the Series A Preferred Units at the Conversion Rate then in effect with respect to the Subordinated Units or Common Units, as applicable. The Partnership will not effect any such consolidation, merger or sale unless prior to the consummation thereof the successor Entity (if other than the Partnership) resulting from such consolidation or merger or the Person purchasing such assets shall expressly assume by written instrument the obligation to deliver to each such holder such stock, securities, cash or other property as, in accordance with the foregoing provisions, such holder may be entitled to acquire and receive.

If any event occurs as to which, in the good faith opinion of the General Partner, the provisions of this Paragraph 7 are not strictly applicable or if strictly applicable would not fairly protect the rights of the Series A Preferred Unitholders in accordance with the essential intent and principles of such provisions, then the General Partner shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such rights as aforesaid.

Whenever a Conversion Rate or Conversion Price shall be adjusted as provided in this Paragraph 7, the General Partner shall forthwith file at the principal office of the Partnership a statement, signed by the General Partner, showing in reasonable detail the facts requiring such adjustment and the Conversion Price and the Conversion Rate that will be effective after such adjustment. Upon written request, the General Partner shall provide the requesting Series A Preferred Unitholder with the then applicable Conversion Prices and Conversion Rates for the Series A Preferred Units.

8.	Redemption

With respect to each Scheduled Redemption Date, each Series A Preferred Unitholder may, upon written notice (the “Holder Redemption Notice”) given to the Partnership not earlier than the November 1 preceding such Scheduled Redemption Date and not later than the later of (i) the March 31 following such Scheduled Redemption Date or (ii) 15 Business Days following the filing of the Partnership’s Annual Report on Form 10-K (such later date being the “Annual Redemption/Conversion Deadline”), require the Partnership to redeem (to the extent that such redemption shall not violate any applicable provisions of the Partnership Act or other Applicable Laws) from such Series A Preferred Unitholder effective as of each Scheduled Redemption Date, for a cash price per Series A Preferred Unit equal to the sum of the Series A Preferred Investment Amount plus the Unpaid Series A Preferred Yield accrued through the Scheduled Redemption Date (such aggregate amount, the “Holder Redemption Price”), a number of Series A Preferred Units not in excess of the Maximum Annual Redemption of such Series A Preferred Unitholder. As promptly as practicable and in any event not later than the later of the Scheduled Redemption Date or 10 days after the receipt of a Holder Redemption Notice pursuant to this Paragraph 8, the Partnership shall pay to the redeeming Series A Preferred Unitholder the Holder Redemption Price plus, in the event of a payment after the Scheduled Redemption Date, interest on the Holder Redemption Price at the Yield Rate from the Scheduled Redemption Date until the date paid to the redeeming Series A Preferred Unitholder.

If the Partnership has made a Representation Breach, a Specified Series A Investor may notify the General Partner (a “Representation Breach Notice”) of the Representation Breach and each Series A Preferred Unitholder shall have the right to require the Partnership to redeem its Series A Preferred Units for a cash price per Series A Preferred Unit equal to the Holder Redemption Price. If the General Partner disputes the occurrence of a Representation Breach, then an independent third party arbitrator shall determine if a Representation Breach occurred, which arbitrator shall be jointly selected by the General Partner and the Specified Series A Investors holding a majority of the Series A Preferred Units held by the Specified Series A Investors sending a Representation Breach Notice. The expense of the arbitrator shall be borne by the Partnership if the arbitrator determines that a Representation Breach occurred or by the Specified Series A Investors sending a Representation Breach Notice if the arbitrator

Annex A-12

determines that a Representation Breach did not occur. The General Partner shall provide the Series A Preferred Unitholders prompt notice following the final determination of the occurrence of a Representation Breach and for 60 days after such notice each Series A Preferred Unitholder shall have the right to send a Holder Redemption Notice to the General Partner. Upon receipt of a Holder Redemption Notice pursuant to this Paragraph 8(b), the Partnership shall redeem one-third of the number of Series A Preferred Units for which a Series A Preferred Unitholder requests redemption on December 31 of each of the calendar year in which such Holder Redemption Notice is received and the two following calendar years; provided, however, that in the event of a Change of Control or a liquidation occurring prior to redemption of such Series A Preferred Units in full pursuant to this Paragraph 8(b), the Partnership shall redeem 100% of such unredeemed Series A Preferred Units on the date of consummation of such Change of Control or the date of the first liquidating distribution pursuant to Paragraph 13(d), as applicable, at a cash price per Series A Preferred Unit equal to the Holder Redemption Price. For purposes of clarity, the Unpaid Series A Preferred Yield shall continue to accrue at the Yield Rate on each outstanding Series A Preferred Unit until redeemed.

If Carter is no longer chief executive officer of the General Partner or any successor general partner of the Partnership or otherwise actively involved in the investment decisions, management and operations of the Partnership (“Key Man Event”), a Series A Preferred Unitholder may notify the General Partner of its objection (“Key Man Objection Notice”), and each Series A Preferred Unitholder shall have the right to require the Partnership to redeem its Series A Preferred Units for a cash price per Series A Preferred Unit equal to the Holder Redemption Price; provided, however, that if the General Partner disputes the occurrence of a Key Man Event, then an independent third party arbitrator shall determine if a Key Man Event occurred, which arbitrator shall be jointly selected by the General Partner and the Series A Preferred Unitholders holding a majority of the Series A Preferred Units held by the Series A Unitholders sending a Key Man Objection Notice. The expense of the arbitrator shall be borne by the Partnership if the arbitrator determines that a Key Man Event occurred or by the Series A Preferred Unitholders sending a Key Man Objection Notice if the arbitrator determines that a Key Man Event did not occur. The General Partner shall provide the Series A Preferred Unitholders prompt notice following the final determination of the occurrence of a Key Man Event, and for 60 days after such notice, each Series A Preferred Unitholder shall have the right to send a Holder Redemption Notice to the General Partner. Upon receipt of a Holder Redemption Notice pursuant to this Paragraph 8(c), the Partnership shall redeem one-third of the number of Series A Preferred Units for which a Series A Preferred Unitholder requests redemption on December 31 of each of the calendar year in which such Holder Redemption Notice is received and the two following calendar years; provided, however, that in the event of a Change of Control or a liquidation occurring prior to redemption of such Series A Preferred Units in full pursuant to this Paragraph 8(c), the Partnership shall redeem 100% of such unredeemed Series A Preferred Units on the date of consummation of such Change of Control or the date of the first liquidating distribution pursuant to Paragraph 13(d), as applicable, at a cash price per Series A Preferred Unit equal to the Holder Redemption Price. For purposes of clarity, the Unpaid Series A Preferred Yield shall continue to accrue at the Yield Rate on each outstanding Series A Preferred Unit until redeemed.

If on any Redemption Date the Partnership is unable to redeem any Series A Preferred Units designated for redemption in the Holder Redemption Notice for any reason, including because such redemption would violate the Partnership Act or other Applicable Laws, then the Partnership shall redeem, pro rata among the Series A Preferred Unitholders who have given a Holder Redemption Notice (based on the number of Series A Preferred Units held by such redeeming Series A Preferred Unitholders as of such Redemption Date), as many of such Series A Preferred Units as may be redeemed, and as soon thereafter as the Partnership is able the Partnership shall redeem, pro rata among the Series A Preferred Unitholders who have given a Holder Redemption Notice (based on the number of Series A Preferred Units held by such redeeming Series A Preferred Unitholders as of such Redemption Date), such unredeemed Series A Preferred Units for which a Series A Preferred Unitholder has given a Holder Redemption Notice; provided, however, that notwithstanding the provisions of this Paragraph 8(d), the

Annex A-13

Partnership shall be deemed to be in Default if the Partnership is unable to redeem in accordance with this Agreement (without giving effect to this Paragraph 8(d)) all of the Series A Preferred Units designated for redemption in the Holder Redemption Notice.

In the event that a Series A Preferred Unitholder gives a Holder Redemption Notice pursuant to Paragraph 8(a) with respect to any Scheduled Redemption Date, after first complying with Paragraph 10, the Partnership shall have the option to redeem (to the extent that such redemption shall not violate the Partnership Act or other Applicable Laws) from such Series A Preferred Unitholder, for a cash price per Series A Preferred Unit equal to the greater of (i) the Holder Redemption Price or (ii) the Interest Fair Market Value of the Common Units and Subordinated Units into which such Series A Preferred Units so redeemed are convertible on such Scheduled Redemption Date at the then applicable Conversion Prices and Conversion Rates (the “Partnership Redemption Price”), a number of Series A Preferred Units not in excess of the number of Series A Preferred Units designated for redemption by such Series A Preferred Unitholder in such Holder Redemption Notice; provided, however, that the Partnership shall not exercise the redemption rights pursuant to this Paragraph 8(e) while a Default by the Partnership is continuing. The Partnership shall exercise its right to redeem pursuant to this Paragraph 8(e) by notifying such redeeming Series A Preferred Unitholder of the number of additional Series A Preferred Units being redeemed on the applicable Scheduled Redemption Date, which notice need not be provided in advance of the payment of the Partnership Redemption Price therefor. The Partnership shall pay to the redeeming Series A Preferred Unitholder the Partnership Redemption Price plus, in the event of a payment after the Scheduled Redemption Date, interest on the Partnership Redemption Price at the Yield Rate from the Scheduled Redemption Date until the date paid in full to the redeeming Series A Preferred Unitholder, concurrent with the payment to the redeeming Series A Preferred Unitholder pursuant to Paragraph 8(a). In the event that the Partnership elects to redeem a portion but not all of the Series A Preferred Units subject to redemption under this Paragraph 8(e), then the Partnership shall to the maximum extent possible effect such redemption pro rata among the Series A Preferred Unitholders who have given a Holder Redemption Notice (based on the number of Series A Preferred Units requested for redemption by such redeeming Series A Preferred Unitholders in connection with the applicable Scheduled Redemption Date).

In the event of a Change of Control or anticipated Change of Control, except with respect to any Series A Preferred Unit a Series A Preferred Unitholder elects to convert pursuant to Paragraph 5(a), the Partnership shall redeem (to the extent that such redemption shall not violate the Partnership Act or other Applicable Laws) at the Holder Redemption Price (determined by treating the Redemption Date as the Scheduled Redemption Date) the Series A Preferred Units upon the consummation of the Change of Control. The Partnership shall provide at least 15 Business Days prior notice to the Series A Preferred Unitholders of (i) the redemption pursuant to this Paragraph 8(f), (ii) the proposed Change of Control, (iii) the consideration that a holder of one Common Unit and a holder of one Subordinated Unit would receive in connection with such Change of Control, determined on a fully-diluted basis as if all Convertible Securities were first converted, exchanged or exercised in full, and (iv) if other than cash or marketable securities, the Board of Director’s good faith valuation of any such consideration and any support for such valuation, and (v) the Redemption Date (which will be the closing date of the consummation of the Change of Control), which redemption pursuant to this Paragraph 8(f) shall be conditioned upon and subject to the consummation of the Change of Control.

Unless there has been a Default, no Series A Preferred Unitholder may Dispose of or convert any Series A Preferred Units (i) with respect to which it has given a Holder Redemption Notice or (ii) which are subject to the Partnership’s option to redeem pursuant to Paragraph 8(e).

From and after the redemption of any Series A Preferred Units in full, all rights of the holders with respect to the Series A Preferred Units redeemed (except the right to receive the Holder Redemption Price or Partnership Redemption Price, as the case may be, plus interest if applicable) shall cease with respect to such Series A Preferred Units, and such Series A Preferred Units shall not thereafter be transferred on the books of the Partnership and shall be deemed to no longer be outstanding for any purpose whatsoever.

Annex A-14

Except as provided in Paragraph 8(e), the Partnership shall have no option to redeem the Series A Preferred Units. Nothing contained herein shall prevent or restrict the purchase by the Partnership, from time to time either at public or private sale, of the whole or any part of the Series A Preferred Units at such price or prices as the General Partner may determine, subject to the provisions of the Partnership Act and other Applicable Laws; provided, however, that at least 10 days prior to such sale, each of the Series A Preferred Unitholders shall be offered the right to sell to the Partnership its pro rata portion (based on the number of Series A Preferred Units held) of the Series A Preferred Units being sold to the Partnership for the same price(s) and terms as the Series A Preferred Units are then being sold to the Partnership.

Upon any redemption, the Partnership shall make a cash payment to the redeeming Series A Preferred Unitholder, and the redeeming Series A Preferred Unitholder shall make a cash payment to the Partnership, to adjust for any distributions declared in respect of the Common Units the Subordinated Units or the Series A Preferred Units after the applicable Redemption Date but prior to the implementation of the redemption, the intent being to put both the redeeming Series A Preferred Unitholder and the Partnership in the same position that they would have been if the redemption had been implemented on the Redemption Date. Any cash payment made pursuant to the preceding sentence shall be treated as (i) a distribution to the Series A Preferred Unitholder if made by the Partnership and (ii) a Capital Contribution if made by the Series A Preferred Unitholder.

9.	Additional Information

In addition to the information to be provided to Unitholders pursuant to Section 8.3 of the Partnership Agreement, (i) the General Partner agrees to provide each Series A Preferred Unitholder with the annual reserve engineering report regarding not less than a majority of the Partnership producing oil and gas properties prepared by an independent reserve engineering firm selected by the General Partner and (ii) on the request of a Series A Preferred Unitholder, the General Partner shall provide such Series A Preferred Unitholder, to the extent permitted by Applicable Law, with a schedule of the Budgeted Distributions in respect of any calendar year for which such information is available. On a Series A Preferred Unitholder’s request, the General Partner agrees to discuss with such Series A Preferred Unitholder the General Partner’s possible exercise of its right to redeem additional Series A Preferred Units from such Series A Preferred Unitholder pursuant to Paragraph 8(e) if such Series A Preferred Unitholder sends a Holder Redemption Notice pursuant to Paragraph 8(a).

10.	Information on Liquidation

The General Partner shall provide the Series A Preferred Unitholders with at least 15 Business Days’ notice of the first liquidating distribution pursuant to Paragraph 13(d) (the “Liquidation Notice”). The Liquidation Notice shall include the General Partner’s good faith estimate of the amount of distributions that a holder of one Subordinated Unit or one Common Unit would receive pursuant to Paragraph 13(d), estimated on a fully-diluted basis as if all Convertible Securities were converted, exchanged or exercised in full.

11.	Documents Executed as Attorney-in-Fact

The General Partner shall provide each Series A Preferred Unitholder with a copy of any amendment, certificate, instrument or any other document for which the power of attorney provided for in Section 2.8 of the Partnership Agreement is exercised in respect of such Series A Preferred Unitholder.

12.	Restricted Transferability

No Series A Preferred Unitholder may Dispose of its Series A Preferred Units to a Person other than a Permitted Transferee without the consent of the General Partner, such consent not to be unreasonably withheld. The General Partner shall have the right to cause the Partnership to purchase all of the Series A Preferred Units proposed to be Disposed of by such Series A Preferred Unitholder for the minimum price per Series A Preferred Unit for which such Series A Preferred Unitholder offers to sell its Series A Preferred Units. If the Partnership does not elect to purchase all of the disposing Series A Preferred

Annex A-15

Unitholder’s offered Series A Preferred Units in accordance with this Paragraph 12(a), the disposing Series A Preferred Unitholder shall then have 90 days within which to Dispose of the offered Series A Preferred Units to a Partner or Partners or a third party for a price at least equal to that described in its offer to the Partnership. The assignee in any such Disposition shall be permitted to assume all of the rights and obligations of the selling Series A Preferred Unitholder. The General Partner must, if it desires to purchase the Series A Preferred Units being offered, exercise its rights pursuant to this Paragraph 12(a) within 15 Business Days following receipt from a Series A Preferred Unitholder of its offer to sell its Series A Preferred Units.

13.	Allocations and Distributions

Allocations for Capital Account Purposes. Notwithstanding Section 6.1 of the Partnership Agreement, for purposes of maintaining the Capital Accounts and in determining the rights of the Partners among themselves, the Partnership’s items of income, gain, loss, deduction, amount realized and Simulated Gain (computed in accordance with Section 5.4(b) of the Partnership Agreement) for each taxable period shall be allocated among the Partners, and the Capital Accounts of the Partners shall be adjusted for Simulated Depletion and Simulated Loss, as provided herein below. Consistent with Section 5.4(d) of the Partnership Agreement, the taxable periods for which allocations shall be made pursuant to this Paragraph 13 shall include any taxable periods ending on a Redemption Date or a Conversion Date, as applicable, and any Series A Preferred Units being redeemed or converted on such date shall be treated as Outstanding as of the last day of the taxable period ending on such date for purposes of this Paragraph 13.

provided, that Net Loss shall not be allocated pursuant to this Paragraph 13(a)(i)(2) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account).

ii.

Net Termination Gains and Losses. After giving effect to the Capital Account adjustments pursuant to Paragraph 13(a)(iv)(2), Net Termination Gain or Net Termination Loss occurring

Annex A-16

during a taxable period shall be allocated in the manner set forth in this Paragraph 13(a)(ii). All allocations under this Paragraph 13(a)(ii) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Paragraph 13(a) and after all distributions of cash and cash equivalents provided under Paragraph 13(c) have been made; provided, however, that solely for purposes of this Paragraph 13(a)(ii), Capital Accounts shall not be adjusted for distributions made pursuant Paragraph 13(d); and provided, further, that Net Termination Gain or Net Termination Loss attributable to (i) Liquidation Gain or Liquidation Loss shall be allocated on the last day of the taxable period during which such Liquidation Gain or Liquidation Loss occurred, (ii) Sale Gain or Sale Loss shall be allocated as of the time of the sale or disposition giving rise to such Sale Gain or Sale Loss and allocated to the Partners consistent with the second proviso set forth in Paragraph 13(b)(vii) and (iii) Revaluation Gain or Revaluation Loss shall be allocated on the date of the Revaluation Event giving rise to such Revaluation Gain or Revaluation Loss.

(1)

Except as provided in Paragraph 13(a)(ii)(4) and subject to the provisions set forth in the last sentence of this Paragraph 13(a)(ii)(1), Net Termination Gain (including a pro rata part of each item of income, gain, loss, deduction, and, to the extent provided in Paragraph 13(a)(iv)(3), Simulated Gain taken into account in computing Net Termination Gain) shall be allocated in the following order and priority:

(a)

First, to each Partner having a deficit balance in its Adjusted Capital Account, in the proportion that such deficit balance bears to the total deficit balances in the Adjusted Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Adjusted Capital Account;

(b)

Second, to all Unitholders holding Common Units, Pro Rata, until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Initial Unit Price, (2) if the Net Termination Gain is attributable to Liquidation Gain, the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Paragraph 13(c)(i) with respect to such Common Unit for such Quarter that is treated as made pursuant to Section 6.4(a)(i) or Section 6.4(b) of the Partnership Agreement (the amount determined pursuant to this clause (2) is hereinafter referred to as the “Unpaid MQD”) and (3) any then existing Cumulative Common Unit Arrearage with respect to such Common Unit;

(c)

Third, if such Net Termination Gain is recognized (or is deemed to be recognized) prior to the conversion of the last Outstanding Subordinated Unit into a Common Unit, to all Unitholders holding Subordinated Units, Pro Rata, until the Capital Account in respect of each Subordinated Unit then Outstanding equals the sum of (1) its Unrecovered Initial Unit Price, determined for the taxable period (or portion thereof) to which this allocation of gain relates, and (2) if the Net Termination Gain is attributable to Liquidation Gain, the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Paragraph 13(c)(iii) with respect to such Subordinated Unit for such Quarter that is treated as made pursuant to Section 6.4(a)(iii) of the Partnership Agreement; and

(d)

Finally, 100% to all Unitholders, Pro Rata.

(2)

Except as otherwise provided by Paragraph 13(a)(ii)(3) or Paragraph 13(a)(ii)(4), Net Termination Loss (including a pro rata part of each item of income, gain, loss, deduction, and, to the extent provided in Paragraph 13(a)(iv)(3), Simulated Gain taken into account in computing Net Termination Loss) shall be allocated:

(a)

First, if Subordinated Units remain Outstanding, to all Unitholders holding Subordinated Units, Pro Rata, until the Adjusted Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero;

Annex A-17

(b)

Second, to all Unitholders holding Common Units, Pro Rata, until the Adjusted Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; and

(c)

Third, the balance, if any, 100% to the General Partner.

(3)

Net Termination Loss attributable to Revaluation Loss and deemed recognized prior to the conversion of the last Outstanding Subordinated Unit and prior to the Liquidation Date shall be allocated:

(a)

First, to the Unitholders, Pro Rata, until the Capital Account in respect of each Common Unit then Outstanding equals the Event Issue Value; provided that Net Termination Loss shall not be allocated pursuant to this Paragraph 13(a)(ii)(3)(a) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit in its Adjusted Capital Account);

(b)

Second, to all Unitholders holding Subordinated Units, Pro Rata; provided that Net Termination Loss shall not be allocated pursuant to this Paragraph 13(a)(ii)(3)(b) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit in its Adjusted Capital Account); and

(c)

Third, the balance, if any, to the General Partner.

(4)

If (A) a Net Termination Loss has been allocated pursuant to Paragraph 13(a)(ii)(3), (B) a Net Termination Gain or Net Termination Loss subsequently occurs (other than as a result of a Revaluation Event) prior to the conversion of the last Outstanding Subordinated Unit and (C) after tentatively making all allocations of such Net Termination Gain or Net Termination Loss provided for in Paragraph 13(a)(ii)(1) or Paragraph 13(a)(ii)(2), as applicable, the Capital Account in respect of each Common Unit then Outstanding does not equal the amount such Capital Account would have been if Paragraph 13(a)(ii)(3) had not been part of this Agreement and all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Paragraph 13(a)(ii)(1) or Paragraph 13(a)(ii)(2), as applicable, then items of income, gain, loss and deduction included in such Net Termination Gain or Net Termination Loss, as applicable, shall be specially allocated to the General Partner and all Unitholders in a manner that will, to the maximum extent possible, cause the Capital Account in respect of each Common Unit then Outstanding to equal the amount such Capital Account would have been if all allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Paragraph 13(a)(ii)(1) or Paragraph 13(a)(ii)(2), as applicable.

iii.

Special Allocations. Notwithstanding any other provision of this Paragraph 13(a), the following special allocations shall be made for each taxable period in the following order:

(1)

Partnership Minimum Gain Chargeback. Notwithstanding any other provision of this Paragraph 13(a), if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income, gain and Simulated Gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Paragraph 13(a)(iii), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income, gain and Simulated Gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Paragraph 13(a)(iii) with respect to such taxable period (other than an allocation pursuant to Paragraphs 13(a)(iii)(6) and 13(a)(iii)(7)). This Paragraph 13(a)(iii)(1) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

Annex A-18

(2)

Chargeback of Partner Nonrecourse Debt Minimum Gain. Notwithstanding the other provisions of this Paragraph 13(a) (other than Paragraph 13(a)(iii)(1)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income, gain and Simulated Gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Paragraph 13(a)(iii), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income, gain and Simulated Gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Paragraph 13(a)(iii), other than Paragraph 13(a)(iii)(1) and other than an allocation pursuant to Paragraphs 13(a)(iii)(6) and 13(a)(iii)(7), with respect to such taxable period. This Paragraph 13(a)(iii)(2) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(3)

Priority Allocations.

(a)

If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Paragraph 13(d)) with respect to an Outstanding Unit for a taxable period exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Outstanding Unit for the same taxable period (the amount of the excess, an “Excess Distribution” and the Unit with respect to which the greater distribution is paid, an “Excess Distribution Unit”), then there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Paragraph 13(a)(iii)(3)(a) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution.

(b)

Series A Preferred Unitholder Periodic Allocations. After the application of Paragraph 13(a)(iii)(3)(a), the remaining Partnership items of gross income and gain (including Unrealized Gain and Simulated Gain) for the taxable period shall be allocated to the Series A Preferred Unitholders, Pro Rata, in the following order:

(i)

first, an amount equal to the excess, if any, of (x) the cumulative Series A Preferred Yield from the Closing Date through the last day of such taxable period with respect to each Series A Preferred Unit that is Outstanding as of the last day of such taxable period, over (y) the cumulative gross income and gain allocated pursuant to this Paragraph 13(a)(iii)(3)(b)(i) from all prior taxable periods with respect to each Series A Preferred Unit that is Outstanding as of the last day of such taxable period;

(ii)

second, an amount equal to the excess, if any, of (x) the cumulative amount of distributions made pursuant to Paragraph 13(c)(iv) from the Closing Date through the last day of such taxable period (including any distributions made with respect to such taxable period within thirty (30) days of the end of such taxable period) with respect to each Series A Preferred Unit that is Outstanding as of the last day of such taxable period, over (y) the cumulative gross income and gain allocated pursuant to this Paragraph 13(a)(iii)(3)(b)(ii) from all prior taxable periods with respect to each Series A Preferred Unit that is Outstanding as of the last day of such taxable period; and

(c)

Holder Redemption Allocations. If any Series A Preferred Units are redeemed pursuant to Paragraph 8 (other than Paragraph 8(e)) and the Capital Account with respect to each such Unit does not equal the Holder Redemption Price, then items of gross income, gain, loss and deduction will be allocated to the Series A Unitholders whose Units are being redeemed, Pro Rata, in a manner such that, to the extent possible, the Capital Account balance with respect to each such Series A Unit equals the Holder Redemption Price; provided that such Capital Account balance shall be determined after giving effect to (x) all Capital Contributions made with respect to such Series A Preferred Unit, including any Capital Contributions made pursuant to Paragraph 8(j), (y) all distributions made with respect to such Series A Preferred Unit, including any distributions made pursuant to Paragraph 13(c) with respect to Unpaid Series A Preferred Yield as of the Redemption Date, and (z) all allocations made pursuant to this Paragraph 13 with respect to such Series A Preferred Unit for all periods. If, after making such allocations, the Capital Account balance with respect to each such Series A Unit does not equal the Holder Redemption Price, then (i) to the extent the Holder Redemption Price exceeds such Capital Account balance, the Partnership will make a guaranteed payment to the Series A Preferred Unitholders whose Series A Preferred Units are being redeemed in an aggregate amount equal to the amount of such excess for each Series A Preferred Unit being redeemed, and the deduction with respect to the guaranteed payments will be allocated 100% to the Common Unitholders, Pro Rata, or (ii) to the extent such Capital Account balance exceeds the Holder Redemption Price, the Partnership will make a guaranteed payment to the Common Unitholders, Pro Rata, in an aggregate amount equal to the amount of such excess for each Series A Preferred Unit being redeemed, and the deduction with respect to the guaranteed payments will be allocated 100% to the Series A Preferred Unitholders, Pro Rata.

(d)

Partnership Redemption Allocations. If any Series A Preferred Units are redeemed pursuant to Paragraph 8(e) and the Capital Account with respect to each such Unit does not equal the Partnership Redemption Price, then items of gross income, gain, loss and deduction will be allocated to the Series A Unitholders whose Units are being redeemed, Pro Rata, in a manner such that, to the extent possible, the Capital Account balance with respect to each such Series A Unit equals the Partnership Redemption Price; provided that such Capital Account balance shall be determined after giving effect to (x) all Capital Contributions made with respect to such Series A Preferred Unit, including any Capital Contributions made pursuant to Paragraph 8(j), (y) all distributions made with respect to such Series A Preferred Unit, including any distributions made pursuant to Paragraph 13(c) with respect to Unpaid Series A Preferred Yield as of the Redemption Date, and (z) all allocations made pursuant to this Paragraph 13 with respect to such Series A Preferred Unit for all periods. If, after making such allocations, the Capital Account balance with respect to each such Series A Unit does not equal the Partnership Redemption Price, then (i) to the extent the Partnership Redemption Price exceeds such Capital Account balance, the Partnership will make a guaranteed payment to the Series A Preferred Unitholders whose Series A Preferred Units are being redeemed in an aggregate amount equal to the amount of such excess for each Series A Preferred Unit being redeemed, and the deduction with respect to the guaranteed payments will be allocated 100% to the Common Unitholders, Pro Rata, or (ii) to the extent such Capital

Annex A-20

Account balance exceeds the Partnership Redemption Price, the Partnership will make a guaranteed payment to the Common Unitholders, Pro Rata, in an aggregate amount equal to the amount of such excess for each Series A Preferred Unit being redeemed, and the deduction with respect to the guaranteed payments will be allocated 100% to the Series A Preferred Unitholders, Pro Rata.

(e)

Liquidation Allocations. If upon the liquidation of the Partnership, the Capital Account with respect to each Series A Preferred Unit (after giving effect to all (i) contributions and distributions and (ii) allocations pursuant to this Paragraph 13 for all periods) does not equal the Series A Liquidation Preference Amount, then items of gross income, gain, loss and deduction will be allocated to the Series A Unitholders, Pro Rata, in a manner such that, to the extent possible, the Capital Account balance with respect to each such Series A Unit equals the Series A Liquidation Preference. If, after making such allocations, the Capital Account balance with respect to each such Series A Unit does not equal the Series A Liquidation Preference Amount, then (i) to the extent the Series A Liquidation Preference Amount exceeds such Capital Account balance, the Partnership will make a guaranteed payment to the Series A Preferred Unitholders, Pro Rata, in an aggregate amount equal to the amount of such excess for each Series A Preferred Unit, and the deduction with respect to the guaranteed payments will be allocated 100% to the Common Unitholders, Pro Rata, or (ii) to the extent such Capital Account balance exceeds the Series A Liquidation Preference Amount, the Partnership will make a guaranteed payment to the Common Unitholders, Pro Rata, in an aggregate amount equal to the amount of such excess for each Series A Preferred Unit, and the deduction with respect to the guaranteed payments will be allocated 100% to the Series A Preferred Unitholders, Pro Rata.

(f)

Interest Yield Payments. Any interest paid on the Holder Redemption Price at the Yield Rate pursuant to Paragraph 8(a) or on the Partnership Redemption Price at the Yield Rate pursuant to Paragraph 8(e) shall be treated as a Code Section 707(c) guaranteed payment and the items of deduction attributable to such guaranteed payment shall be allocated 100% to the Common Unitholders, Pro Rata.

(4)

Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that an allocation pursuant to this Paragraph 13(a)(iii)(4) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Paragraph 13(a) have been tentatively made as if this Paragraph 13(a)(iii)(4) were not in this Agreement.

(5)

Gross Income Allocations. In the event any Partner has a deficit balance in its Capital Account at the end of any taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income, gain and Simulated Gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Paragraph 13(a)(iii)(5) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account after all other allocations provided for in this Paragraph 13(a) have been tentatively made as if Paragraph 13(a)(iii)(4) and this Paragraph 13(a)(iii)(5) were not in this Agreement.

Annex A-21

(6)

Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Common Unitholders, Pro Rata. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements.

(7)

Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss. This Paragraph 13(a)(iii)(7) is intended to comply with Treasury Regulations Section 1.704-2(i)(1) and shall be interpreted consistently therewith.

(8)

Nonrecourse Liabilities. For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Common Unitholders, Pro Rata.

(9)

Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) of the Code (including pursuant to Treasury Regulation Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts as a result of a distribution to a Partner in complete liquidation of such Partner’s interest in the Partnership, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain or Simulated Gain (if the adjustment increases the basis of the asset) or loss or Simulated Loss (if the adjustment decreases such basis) taken into account pursuant to Section 5.4 of the Partnership Agreement, and such item of gain, loss, Simulated Gain or Simulated Loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(10)

Economic Uniformity; Changes in Law.

(a)

At the election of the General Partner with respect to any taxable period ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to Paragraph 13(a)(iii)(3), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the proportion of the number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such Final Subordinated Units to an amount that after taking into account the other allocations of income, gain, loss and deduction to be made with respect to such taxable period will equal the product of (i) the number of Final Subordinated Units held by such Partner and (ii) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Final Subordinated Units into Common Units. This allocation method for establishing such economic uniformity will be available to the General Partner only if the method for

Annex A-22

allocating the Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.4(c)(ii) of the Partnership Agreement does not otherwise provide such economic uniformity to the Final Subordinated Units.

(b)

For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (iii) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Annex as provided in this Paragraph 13(a)(iii)(10) only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Outstanding Limited Partner Interests or the Partnership.

(11)

Curative Allocation.

(a)

Notwithstanding any other provision of this Paragraph 13(a), other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of gross income, gain, loss, deduction, Simulated Depletion, Simulated Gain and Simulated Loss allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Paragraph 13(a) and Simulated Depletion and Simulated Loss had been included in the definition of Net Income and Net Loss. In exercising its discretion under this Paragraph 13(a)(iii)(11)(a), the General Partner may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made. Allocations pursuant to this Paragraph 13(a)(iii)(11)(a) shall only be made with respect to Required Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners.

(b)

The General Partner shall, with respect to each taxable period, (1) apply the provisions of Paragraph 13(a)(iii)(11)(a) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Paragraph 13(a)(iii)(11)(a) among the Partners in a manner that is likely to minimize such economic distortions.

(12)

Special Curative Allocation in Event of Certain Liquidations. Notwithstanding any other provision of this Paragraph 13(a) (other than the Required Allocations), if (1) the Liquidation Date occurs prior to the conversion of the last Outstanding Subordinated Unit and (2) after having made all other allocations provided for in this Paragraph 13(a) for the taxable period in which the Liquidation Date occurs, the Capital Account in respect of each then Outstanding Common Unit does not equal the amount such Capital Account would have been if Paragraph 13(a)(ii)(3) and Paragraph 13(a)(ii)(4) had not been part of this Agreement and all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Paragraph 13(a)(ii)(1) and Paragraph 13(a)(ii)(2), as applicable, then items of income, gain, loss and deduction for such taxable period shall be reallocated among all Unitholders in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Capital Account in respect of each Common Unit to equal the

Annex A-23

amount such Capital Account would have been if all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Paragraph 13(a)(ii)(1) and Paragraph 13(a)(ii)(2), as applicable. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Capital Account balances described above, (x) items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs shall be reallocated from the Unitholders holding Subordinated Units to Unitholders holding Common Units and (y) items of deduction and loss that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs shall be reallocated from Unitholders holding Common Units to Unitholders holding Subordinated Units. In the event that (1) the Liquidation Date occurs on or before the date (not including any extension of time prescribed by law) for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (2) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Paragraph 13(a)(iii)(12) fails to achieve the Capital Account balances described above, items of income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among the General Partner and all Unitholders in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Paragraph 13(a)(iii)(12), cause the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior allocations of Net Termination Gain and Net Termination Loss had been made pursuant to Paragraph 13(a)(ii)(1) and Paragraph 13(a)(ii)(2), as applicable.

(13)

Allocations of GP Items. All GP Items shall, to the maximum extent possible, be allocated to the Series A Preferred Unitholders and the holders (other than the General Partner) of the Common Units in accordance with the provisions of this Paragraph 13(a).

(14)

Equalization of Capital Accounts With Respect to Privately Placed Units. Unrealized Gain or Unrealized Loss deemed recognized as a result of a Revaluation Event shall first be allocated to the (A) Unitholders holding Privately Placed Units, Pro Rata, or (B) Unitholders holding Common Units (other than Privately Placed Units), Pro Rata, as applicable, to the extent necessary to cause the Capital Account in respect of each Privately Placed Unit then Outstanding to equal the Capital Account in respect of each Common Unit (other than Privately Placed Units) then Outstanding.

(15)

Allocations Regarding Certain Payments Made to Employees and Other Service Providers. Consistent with the provisions of Treasury Regulation Section 1.83-6(d), if any Partner (or its successor) transfers property (including cash) to any employee or other service provider of the Partnership Group and such Partner is not entitled to be reimbursed by (or otherwise elects not to seek reimbursement from) the Partnership for the value of such property, then any items of deduction or loss resulting from or attributable to such transfer shall be allocated to the Partner (or its successor) that made such transfer and was deemed to have contributed such property to the Partnership pursuant to Section 5.8 of the Partnership Agreement.

(16)

Converted Series A Preferred Units; Economic Uniformity. With respect to any taxable period ending upon, or after, a Conversion Date, items of Partnership income, gain, deduction and loss shall be allocated to each Series A Preferred Unitholder holding converted Series A Preferred Units until each such Partner has been allocated an amount of Partnership income, gain, deduction and loss that increases, or decreases, as the case may be, the Capital Account maintained with respect to such converted Series A Preferred Units to an amount equal to the product of (A) the number of converted Series A Preferred Units and (B) the Per Unit Capital Amount for a Common Unit. For purposes of this Paragraph 13(a)(iii)(16), the

Annex A-24

Capital Account maintained with respect to a converted Series A Preferred Unit shall give effect to (i) all Capital Contributions made with respect to such Series A Preferred Unit, including any Capital Contributions made pursuant to Paragraph 5(d) or Paragraph 6(b), (ii) all distributions made with respect to such Series A Preferred Unit, including any distributions made pursuant to Paragraph 13(c) with respect to Unpaid Series A Preferred Yield as of the Conversion Date and pursuant to Paragraph 5(d) or Paragraph 6(b) with respect to the Common Unit into which such Series A Preferred Unit was converted, and (iii) all allocations made pursuant to such converted Series A Preferred Unit for all periods. The purpose for this allocation is to establish uniformity between the Capital Accounts underlying converted Series A Preferred Units and the Capital Accounts underlying Common Units.

iv.

Simulated Basis; Simulated Depletion and Simulated Loss; Simulated Gain; Amount Realized.

(1)

Simulated Basis. For purposes of determining and maintaining the Partners’ Capital Accounts, (i) the initial Simulated Basis of each oil and gas property (as defined in Section 614 of the Code) of the Partnership shall be allocated among the Common Unitholders, Pro Rata and (ii) if the Carrying Value of an oil and gas property (as defined in Section 614 of the Code) is adjusted pursuant to Section 5.4(d) of the Partnership Agreement, the Simulated Basis of such property (as adjusted to reflect the adjustment to the Carrying Value of such property), shall be allocated to the Common Unitholders, Pro Rata.

(2)

Simulated Depletion and Simulated Loss. For purposes of applying clause (z) of the second sentence of Section 5.4(a) of the Partnership Agreement, Simulated Depletion and Simulated Loss with respect to each oil and gas property (as defined in Section 614 of the Code) of the Partnership shall reduce each Partner’s Capital Account in proportion to the manner in which the Simulated Basis of such property is allocated among the Partners pursuant to Paragraph 13(a)(iv)(1).

(3)

Simulated Gain. For purposes of applying clause (iii) of the second sentence of Section 5.4(a) of the Partnership Agreement, Simulated Gain for any taxable period will be treated as included in either Net Income or Net Loss and allocated pursuant to Paragraph 13(a)(i).

(4)

Amount Realized. For purposes of Treasury Regulation Sections 1.704-1(b)(2)(iv)(k)(2) and 1.704-1(b)(4)(iii), the amount realized on the disposition of any oil and gas property (as defined in Section 614 of the Code) of the Partnership shall be allocated (i) first to the Partners in an amount equal to the remaining Simulated Basis of such property in the same proportions as the Simulated Basis of such property was allocated among the Partners pursuant to Paragraph 13(a)(iv)(1), and (ii) any remaining amount realized shall be allocated to the Partners in the same ratio as Simulated Gain from the disposition of such oil and gas property is allocated pursuant to Paragraph 13(a)(i).

Allocations for Tax Purposes

Except as otherwise provided herein, for U.S. federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Paragraph 13(a).

ii.

The deduction for depletion with respect to each separate oil and gas property (as defined in Section 614 of the Code) shall be computed for federal income tax purposes separately by the Partners rather than by the Partnership in accordance with Section 613A(c)(7)(D) of the Code. Except as provided in Paragraph 13(b)(iii), for purposes of such computation (before taking into account any adjustments resulting from an election made by the Partnership under Section 754 of the Code), the adjusted tax basis of each oil and gas property (as defined in Section 614 of the Code) that is (i) a Contributed Property shall initially be allocated among the non-contributing

Annex A-25

Common Unitholders, Pro Rata, but not in excess of any such Partner’s share of Simulated Basis as determined pursuant to Paragraph 13(a)(iv)(1), and (ii) not a Contributed Property or an Adjusted Property shall initially be allocated to the Partners in proportion to each such Partner’s share of Simulated Basis as determined pursuant to Paragraph 13(a)(iv)(1). If there is an event described in Section 5.4(d) of the Partnership Agreement, the General Partner shall reallocate the adjusted tax basis of each oil and gas property in a manner (i) consistent with the principles of Section 704(c) of the Code and (ii) that maintains the federal income tax fungibility of the Units.

iii.

In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for U.S. federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations promulgated under Section 704(b) and 704(c) of the Code, as determined appropriate by the General Partner (taking into account the General Partner’s discretion under Paragraph 13(a)(iii)(10)); provided that, in all events, the General Partner shall apply the “remedial allocation method” in accordance with the principles of Treasury Regulation Section 1.704-3(d). For purposes of applying the “remedial allocation method” to oil and gas properties (i) the amount by which any Partner’s Capital Account is adjusted for Simulated Depletion shall be treated as an amount of book depletion allocated to such Partner and (ii) the amount of cost depletion computed by such Partner under Section 613A(c)(7)(D) of the Code shall be treated as an amount of tax depletion allocated to such Partner.

iv.

The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or any successor regulations thereto. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Units, so long as such conventions would not have a material adverse effect on the Limited Partners or Record Holders of any class or classes of Limited Partner Interests.

In accordance with Treasury Regulation Sections 1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Paragraph 13(b), be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

vi.

All items of income, gain, loss, deduction and credit recognized by the Partnership for U.S. federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code that may be made by the Partnership; provided, however, that such allocations, once made, shall be adjusted (in the manner determined by the General Partner) to take into account those adjustments permitted or required by Sections 734 and 743 of the Code.

Annex A-26

vii.

Each item of Partnership income, gain, loss and deduction shall, for U.S. federal income tax purposes, be determined for each Quarter and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership’s Units are listed or admitted to trading on the first Business Day of each month; provided, however, such items for the period beginning on the Closing Date and ending on the last day of the month in which the Closing Date occurs shall be allocated to the Partners who are issued Units as a result of the transactions contemplated by the Contribution Agreement and the Underwriting Agreement; and provided, further, that each item of Partnership income, gain, loss and deduction for the period beginning on the Contribution Date and ending the date immediately before the Closing Date shall be allocated to the Partners holding Units on the date immediately before the Closing Date; and provided, further, that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income, gain, loss or deduction, as determined by the General Partner, shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership’s Units are listed or admitted to trading on the first Business Day of the month in which such item is recognized for U.S. federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

viii.

Allocations that would otherwise be made to a Partner under the provisions of this Paragraph 13 shall instead be made to the beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method determined by the General Partner.

ix.

If, as a result of an exercise of a Noncompensatory Option, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

Distributions Prior to Liquidation. Notwithstanding Section 6.3(b) of the Partnership Agreement and except as otherwise provided in Paragraph 8, prior to the liquidation of the Partnership in accordance with Section 12.4 of the Partnership Agreement, in the sole discretion of the General Partner, cash or other property of the Partnership shall be distributed to the Partners in the following order and priority; provided, however, that distributions pursuant to clause i below shall be made in cash only:

First, 100% to the Series A Preferred Unitholders (ratably among the Series A Preferred Unitholders based on the aggregate Unpaid Series A Preferred Yield of each such Series A Preferred Unitholder’s Series A Preferred Units accrued through the last day of the immediately preceding calendar quarter), until the aggregate Unpaid Series A Preferred Yield of each such Series A Preferred Unit accrued through the last day of the immediately preceding calendar quarter has been reduced to zero; and then

ii.

Second, in respect of each calendar year, 100% to the Common Unitholders and the Subordinated Unitholders, apportioned in accordance with Sections 6.3, 6.4 and 6.5 of the Partnership Agreement, as applicable, until there has been distributed pursuant to this Paragraph 13(c)(ii) an aggregate amount in respect of such calendar year equal to 10% of the aggregate Interest Fair Market Value of the outstanding Common Units and Subordinated Units as of the first day of such calendar year; and then

iii.

Finally, 100% to the Common Unitholders and the Subordinated Unit holders, on the one hand, and the Series A Preferred Unitholders, on the other hand, Pro Rata. Amounts distributed to the Common and Subordinated Unitholders pursuant to Paragraph 13(c)(i) shall be apportioned in accordance with Sections 6.3, 6.4 and 6.5 of the Partnership Agreement, as applicable.

Annex A-27

Distributions under this Paragraph 13(c) shall be made to the Unitholders each calendar quarter no later than thirty (30) days following the last day of each calendar quarter. The General Partner shall be entitled to establish record dates for the payment of distributions and adopt any other procedures deemed by the General Partner to be necessary or appropriate in order to effect the provisions of this Paragraph 13(c).

Subject to the contractual obligations of the Partnership and the Partnership Act and other Applicable Laws, the Partnership shall distribute to the Unitholders an aggregate amount of cash with respect to each calendar year (for purposes of this Paragraph 13(c), any distribution in January being deemed to be a distribution with respect to the previous calendar year unless such distribution is specified by the General Partner as being deemed to be a distribution with respect to a different calendar year) at least equal to fifty percent (50%) of the Partnership’s EBITDAX for such calendar year, unless otherwise determined by the General Partner.

Promptly following the determination of the Partnership’s EBITDAX for each calendar year, the General Partner shall calculate the cash distributions, if any, to be made to the Unitholders in order to comply with this Paragraph 13(c) and shall make any such additional distribution in respect of such calendar year in order to cause the aggregate cash distributions to Unitholders in respect of such calendar year to meet the requirements of this Paragraph 13(c).

The Partnership will make distributions of (i) cash (other than GP Available Cash), if any, to the Unitholders in accordance with this Paragraph 13(c) and (ii) GP Available Cash, if any, to the Unitholders (other than the General Partner) pursuant to the provisions of this Paragraph 13(c).

Distributions in Liquidation. In connection with the liquidation of the Partnership pursuant to Section 12.4 of the Partnership Agreement, any cash available for distribution in connection with such liquidation shall first be used to make liquidating distributions to the Series A Preferred Unitholders pursuant to and in accordance with Section 12.4(c) of the Partnership Agreement, and any remaining cash of the Partnership shall be distributed to the Common Unitholders and Subordinated Unitholders pursuant to and in accordance with Section 12.4(c) of the Partnership Agreement.

14.	Right to Acquire Limited Partner Interests. Notwithstanding anything herein or in the Partnership Agreement to the contrary, the terms of Article XV of the Partnership Agreement shall not apply while this Annex remains in effect.

15.

Right to Vote Units. Notwithstanding anything to the contrary in the Partnership Agreement, the restrictions in the definition of “Outstanding” that apply to Persons that beneficially own 15% or more of any class of Partnership Interests shall not restrict a Series A Preferred Unitholder from voting all, and being deemed present with respect to all, of his, her or its Series A Preferred Units on any matter.

16.

Other Modifications to Partnership Agreement. For purposes of determining the Percentage Interest of any Unitholder with respect to Series A Preferred Units as of any date of determination, each Series A Preferred Unit shall be deemed to have converted into the number of Common Units and Subordinated Units into which such Series A Preferred Unit is convertible as of such date at the then applicable Conversion Price and Conversion Rate, and such Common Units and Subordinated Units shall be deemed to be Outstanding Units and such Series A Preferred Units shall be deemed not to be Outstanding Units.

17.	Invalidity of Provisions.

If any provision or part of a provision of this Annex is or becomes, for any reason, invalid, illegal or unenforceable in any respect (including because the enactment of such provision or part of a provision was prohibited by the Organizational LP Partnership Agreement), the validity, legality and enforceability of the remaining provisions and part thereof contained herein shall not be affected thereby, and this Annex shall, to the fullest extent permitted by law, be reformed and construed as if such invalid, illegal or unenforceable provision, or part of a provision, had never been contained herein, and such provision or part reformed so that it would be valid, legal and enforceable to the maximum extent possible.

Annex A-28

If this Annex, when read together with the Partnership Agreement, fails to include any provision, or part of a provision, from the Organizational LP Partnership Agreement that was required to be included herein (a “required provision”) by virtue of any provision of the Organizational LP Partnership Agreement, this Annex shall, to the fullest extent permitted by law, be reformed and construed as if such provision, or part of a provision, had been included herein (it being understood that any required provision that relates solely to the rights or preferences of the Series A Preferred Units or Unitholders shall be included in this Annex and any other required provision shall be included in the Partnership Agreement). Any provision or part of a provision of this Annex that conflicts with any such required provision shall be reformed and construed as if such conflicting provision had never been contained herein. The terms of this Annex shall only be modified by this Paragraph 14(b) to the extent necessary to give effect to such required provision.

18.	Effectiveness. This Annex shall be deemed to be effective upon execution by the General Partner.

19.

Termination. Except for the right of a holder of Series A Preferred Units to receive Common Units and Subordinated Units and certain payments as expressly set forth in Paragraph 6, in the case of conversion of Series A Preferred Units, or Paragraph 8, in the case of redemption of Series A Preferred Units, this Annex shall automatically terminate and be of no further force and effect at such time as no Series A Preferred Units remain outstanding.

Annex A-29

IN WITNESS WHEREOF, the undersigned has executed this Agreement as of the day and year first written above.

(ee) “Subordinated Unit” means an interest in the Partnership having the rights and obligations specified with respect to Subordinated Units in the Partnership Agreement. The term “Subordinated Unit” does not refer to or include a Common Unit.

(ff) “UDR” means a distribution made by the Partnership with respect to a Restricted Unit.

(gg) “Unit” means a Common Unit or a Subordinated Unit. In the context of a particular Award, references in the Plan to a “Unit” shall be a reference to either a Common Unit or a Subordinated Unit, determined based on the type of Units with respect to which such Award is granted.

(hh) “Unit Appreciation Right” or “UAR” means an Award that, upon exercise, entitles the holder to receive the excess of the Fair Market Value of a Unit on the exercise date of the UAR over the exercise price established for such UAR. Such excess may be paid in cash or in Units as determined by the Committee in its discretion and as provided in the applicable Award Agreement.

Section 3. Administration.

(a) Authority of the Committee. The Plan shall be administered by the Committee, subject to Section 3(b); provided, however, that in the event that the Board is not also serving as the Committee, the Board, in its sole discretion, may at any time and from time to time exercise any and all rights and duties of the Committee under the Plan. The governance of the Committee shall be subject to the charter, if any, of the Committee as approved by the Board. Subject to the

following and applicable law, the Committee, in its sole discretion, may delegate any or all of its powers and duties under the Plan, including the power to grant Awards under the Plan, to the Chief Executive Officer of the General Partner, subject to such limitations on such delegated powers and duties as the Committee may impose, if any. Upon any such delegation all references in the Plan to the “Committee”, other than in Section 7, shall be deemed to include the Chief Executive Officer; provided, however, that such delegation shall not limit the Chief Executive Officer’s right to receive Awards under the Plan. Notwithstanding the foregoing, the Chief Executive Officer may not grant Awards to, or take any action with respect to any Award previously granted to, a person who is then an officer subject to Rule 16b-3 or a Director. Subject to the terms of the Plan and applicable law, and in addition to other express powers and authorizations conferred on the Committee by the Plan, the Committee shall have full power and authority to:

(i) designate Participants;

(ii) determine the type or types of Awards to be granted to a Participant;

(iii) determine the number and type of Units to be covered by Awards;

(iv) determine the terms and conditions of any Award, consistent with the terms of the Plan, which terms may include any provision regarding the acceleration of vesting or waiver of forfeiture restrictions or any other condition or limitation regarding an Award, based on such factors as the Committee shall determine, in its sole discretion;

(v) determine whether, to what extent, and under what circumstances Awards may be vested, settled, exercised, canceled, or forfeited;

(vi) interpret and administer the Plan and any instrument or agreement relating to an Award made under the Plan;

(vii) establish, amend, suspend, or waive such rules and regulations and appoint such agents as it shall deem appropriate for the proper administration of the Plan; and

(viii) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan.

The Committee may correct any defect, supply any omission, or reconcile any inconsistency in the Plan, in any Award or in any Award Agreement in such manner and to such extent as the Committee deems necessary or appropriate. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan or any Award shall be within the sole discretion of the Committee, may be made at any time, and shall be final, conclusive, and binding upon all Persons, including the General Partner, the Partnership, any of their respective Affiliates, any Participant, and any beneficiary of any Award.

(b) Authority of a Subcommittee of the Committee. If the Board is not functioning as the Committee, then at any time that a member of the Committee is not a Qualified Member, any action of the Committee relating to an Award granted or to be granted to a Participant who is then subject to Section 16 of the Exchange Act in respect of the Partnership may be taken either

(i) by a subcommittee, designated by the Committee, composed solely of two or more Qualified Members, (ii) by the Committee but with each such member who is not a Qualified Member abstaining or recusing himself or herself from such action; provided, however, that upon such abstention or recusal the Committee remains composed solely of two or more Qualified Members, or (iii) by the full Board. Any such action described in clauses (i), (ii), or (iii) of the preceding sentence shall be deemed to be the action of the Committee for all purposes of the Plan.

(c) Limitation of Liability. The Committee and each member thereof shall be entitled to, in good faith, rely or act upon any report or other information furnished to him or her by any Employee, the General Partner’s or the Partnership’s legal counsel, independent auditors, consultants, or any other agents assisting in the administration of the Plan. Members of the Committee and any Employee acting at the direction or on behalf of the Committee shall not be personally liable for any action or determination taken or made in good faith with respect to the Plan, and shall, to the fullest extent permitted by law, be indemnified and held harmless by the General Partner with respect to any such action or determination.

Section 4. Units.

(a) Limits on Units Deliverable. Subject to adjustment as provided in Section 4(c) and Section 7, the number of Common Units and Subordinated Units, in the aggregate, that may be delivered with respect to Awards under the Plan is 15,148,096. If any Award is forfeited, cancelled, exercised, settled in cash, or otherwise terminates or expires without the actual delivery of Units pursuant to such Award (the grant of Restricted Units is not a delivery of Units for this purpose unless and until the Restricted Period for such Restricted Units lapses), or if any Units under an Award are held back to cover the exercise price or tax withholding (including the withholding of Units with respect to an Award of Restricted Units), then, in either such case, the Units underlying such Awards that are so forfeited, cancelled, exercised, settled in cash or that otherwise terminate or expire without the actual delivery of Units and Units so held back shall be available to satisfy future Awards under the Plan. Notwithstanding any other provision of the Plan to the contrary, the aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all Awards granted to any Director during any single calendar year shall not exceed $500,000; provided, however, that such limitation shall be $600,000 in the first year a Person becomes a Director. There shall not be any limitation on the number of Awards that may be paid in cash.

(b) Sources of Units Deliverable under Awards. Any Units delivered pursuant to an Award shall consist, in whole or in part, of (i) Common Units acquired in the open market; (ii) Common Units or Subordinated Units acquired from the Partnership (including newly issued Common Units or Subordinated Units), any Affiliate of the Partnership, or any other Person; or (iii) any combination of the foregoing, as determined by the Committee in its discretion.

(i) Certain Restructurings. Upon the occurrence of any “equity restructuring” event that could result in an additional compensation expense to the General Partner or the

Partnership pursuant to the provisions of ASC Topic 718 if adjustments to Awards with respect to such event were discretionary, the Committee shall equitably adjust the number and type of Units (or other securities or property) covered by each outstanding Award and the terms and conditions, including the exercise price and performance criteria (if any), of such Award to equitably reflect such event and shall adjust the number and type of Units (or other securities or property) with respect to which Awards may be granted under the Plan after such event; provided, however, that no adjustment to any Award shall materially reduce the benefit to a Participant immediately prior to such adjustment without the consent of such Participant. Upon the occurrence of any other similar event that would not result in an accounting charge under ASC Topic 718 if the adjustment to Awards with respect to such event were subject to discretionary action, the Committee shall have complete discretion to adjust Awards and the number and type of Units (or other securities or property) with respect to which Awards may be granted under the Plan in such manner as it deems appropriate with respect to such other event. In the event the Committee makes any adjustment pursuant to the foregoing provisions of this Section 4(c), the Committee shall make a corresponding and proportionate adjustment with respect to the maximum number of Units that may be delivered with respect to Awards under the Plan as provided in Section 4(a) and the kind of Units or other securities available for grant under the Plan.

(ii) Other Adjustments. Subject to, and without limiting the scope of, the provisions of Section 4(c)(i), in the event that the Committee determines that any distribution (whether in the form of cash, Units, other securities, or other property), recapitalization, split, reverse split, reorganization, merger, Change of Control, consolidation, split-up, spin-off, combination, repurchase, or exchange of Units or other securities of the Partnership, issuance of warrants or other rights to purchase Units or other securities of the Partnership, or other similar transaction or event affects the Units such that an adjustment is determined by the Committee, in its sole discretion, to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (A) the number and type of Units (or other securities or property) with respect to which Awards may be granted, (B) the number and type of Units (or other securities or property) subject to outstanding Awards, and (C) the grant or exercise price with respect to any Award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award; provided, that the number of Units subject to any Award shall always be a whole number. Further, upon the occurrence of any event described in the preceding sentence, the Committee, acting in its sole discretion without the consent or approval of any holder, may effect one or more of the following alternatives, which may vary among individual holders and which may vary among Awards:

(A) remove any applicable forfeiture restrictions on any Award;

(B) accelerate the time of exercisability or the time at which the Restricted Period shall lapse to a specific date specified by the Committee;

(C) require the mandatory surrender to the General Partner or the Partnership by selected holders of some or all of the outstanding Awards held by such holders (irrespective of whether such Awards are then subject to a Restricted Period or other restrictions pursuant to the Plan) as of a date specified by the Committee, in which event the Committee shall thereupon cancel such Awards and cause the General Partner,

the Partnership or any of their respective Affiliates to pay to each holder an amount of cash per Unit equal to the per Unit value as determined by the Committee as of the date determined by the Committee to be the date of cancellation and surrender of such Awards less the exercise price, if any, applicable to such Awards; provided, however, that to the extent the exercise price of an Option or UAR exceeds such per Unit value as determined by the Committee, no consideration will be paid with respect to that Award;

(D) cancel Awards that remain subject to a Restricted Period as of a date specified by the Committee without payment of any consideration to the Participant for such Awards; or

(E) make such adjustments to Awards then outstanding as the Committee deems appropriate to reflect such event (including, without limitation, the substitution of new awards for Awards); provided, however, that the Committee may determine in its sole discretion that no adjustment is necessary to Awards then outstanding.

Section 5. Eligibility. Any Employee, Consultant or Director shall be eligible to be designated a Participant and receive an Award under the Plan.

Section 6. Awards.

(a) Options and UARs. The Committee shall have the authority to determine the Employees, Consultants, and Directors to whom Options or UARs shall be granted, the number of Units to be covered by each Option or UAR, the exercise price therefor, the Restricted Period and other conditions and limitations applicable to the exercise of the Option or UAR, including the following terms and conditions and such additional terms and conditions, as the Committee shall determine, that are not inconsistent with the provisions of the Plan.

(i) Exercise Price. The exercise price per Unit purchasable under an Option or subject to a UAR shall be determined by the Committee at the time the Option or UAR is granted but, except with respect to substitute Awards pursuant to Section 6(f)(viii), may not be less than the Fair Market Value of a Unit as of the date of grant of such Option or UAR.

(ii) Time and Method of Exercise. The Committee shall determine the exercise terms and the Restricted Period, if any, with respect to an Option or UAR, which may include a provision for accelerated vesting upon the achievement of specified performance goals or other events and the method or methods by which payment of the exercise price with respect to an Option or UAR may be made or deemed to have been made, which may include cash, check acceptable to the General Partner, withholding Units having a Fair Market Value on the exercise date equal to the relevant exercise price from the Award, a “cashless-broker” exercise through procedures approved by the General Partner, other securities or other property, a note (in a form acceptable to the General Partner), or any combination of the foregoing methods.

(iii) Forfeitures. Except as otherwise provided in the terms of the Award Agreement, upon termination of a Participant’s employment with (or service to) the General Partner and its Affiliates or membership on the Board, whichever is applicable, for any reason during the applicable Restricted Period, all outstanding Options and UARs awarded to the Participant shall be automatically forfeited on such termination.

(b) Restricted Units and Phantom Units. The Committee shall have the authority to determine the Employees, Consultants, and Directors to whom Restricted Units or Phantom Units shall be granted, the number of Restricted Units or Phantom Units to be granted to each such Participant, the applicable Restricted Period, the conditions under which the Restricted Units or Phantom Units may become vested or forfeited, and such other terms and conditions as the Committee may establish with respect to such Awards, including whether DERs are granted with respect to the Phantom Units.

(i) UDRs. To the extent determined by the Committee, in its discretion, the Award Agreement for a grant of Restricted Units may provide that distributions made by the Partnership with respect to the Restricted Units shall be subject to the same forfeiture and other restrictions as the Restricted Unit and, if restricted, such distributions shall be held, with or without interest or other earnings credit (as determined by the Committee), until the Restricted Unit vests or is forfeited with the UDR being paid or forfeited at the same time, as the case may be. Absent such a restriction on the UDRs in the Award Agreement, UDRs shall be paid to the holder of the Restricted Unit without restriction at the same time as cash distributions are paid by the Partnership to its unitholders.

(ii) Forfeitures. Except as otherwise provided in the terms of the applicable Award Agreement, upon termination of a Participant’s employment with (or service to) the General Partner and its Affiliates or membership on the Board, whichever is applicable, for any reason during the applicable Restricted Period, all outstanding, unvested Restricted Units and Phantom Units awarded to the Participant shall be automatically forfeited on such termination.

(iii) Lapse of Restrictions.

(A) Phantom Units. Unless otherwise provided in the applicable Award Agreement, upon or as soon as reasonably practical following the vesting of each Phantom Unit, subject to Section 8(b), the Participant shall be entitled to settlement of such Phantom Unit and shall receive one Unit (or such greater or lesser number of Units as may be provided pursuant to the applicable Award Agreement) or an amount in cash equal to the Fair Market Value (for purposes of this Section 6(b)(iii), as calculated on the last day of the Restricted Period) of a Unit (or such greater or lesser number of Units as may be provided pursuant to the applicable Award Agreement) or a combination thereof, as determined by the Committee in its discretion and as provided in the applicable Award Agreement.

(B) Restricted Units. Upon or as soon as reasonably practicable following the vesting of each Restricted Unit, subject to Section 8(b), the Participant shall be entitled to have the restrictions removed from his or her Unit certificate (or book entry account, as applicable).

(c) DERs. The Committee shall have the authority to determine the Employees, Consultants, and Directors to whom DERs are granted, whether such DERs are tandem or separate Awards, whether such DERs shall be paid directly to the Participant, be credited to a bookkeeping account (with or without interest or other earnings credit), any vesting restrictions and payment provisions applicable to the DERs, and such other provisions or restrictions as determined by the Committee in its discretion, all of which shall be specified in the applicable

Award Agreements. Distributions in respect of DERs shall be credited as of the distribution dates during the period between the date an Award is granted to a Participant and the date such Award vests, is exercised, is distributed or expires, as determined by the Committee. Such DERs shall be converted to cash, Units, Restricted Units, or Phantom Units by such formula and at such times and subject to such limitations as may be determined by the Committee. Tandem DERs may be subject to the same or different vesting restrictions as the underlying Award, or be subject to such other provisions or restrictions as determined by the Committee in its discretion.

(d) Bonus Units and Awards in Lieu of Obligations. The Committee is authorized to grant Units as a bonus or to grant Units in lieu of obligations to pay cash or deliver other property under the Plan or under other plans or compensatory arrangements to such Employees, Consultants and Directors and in such amounts as the Committee, in its discretion, may select. Bonus Units or Awards granted hereunder shall be subject to such other terms and conditions as shall be determined by the Committee.

(e) Other Unit-Based Awards; Cash Awards. Other Unit-Based Awards may be granted under the Plan to such Employees, Consultants, and Directors as the Committee, in its discretion, may select. An Other Unit-Based Award shall be an award denominated or payable in, valued in or otherwise based on or related to Units, in whole or in part. The Committee shall determine the terms and conditions of any Other Unit-Based Award, including whether such Other Unit-Based Award (or any portion thereof) is fully vested when granted and, if such Other Unit-Based Award (or any portion thereof) is not fully vested when granted, the conditions under which such Other Unit-Based Award (or the unvested portion thereof) may become vested or forfeited. Other Unit-Based Awards may be paid in cash, Units (including Restricted Units) or any combination thereof as provided in the applicable Award Agreement. Cash Awards, as an element of or supplement to, or independent of any other Award under the Plan, may also be granted pursuant to this Section 6(e).

(f) Certain Provisions Applicable to Awards.

(i) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for any other Award granted under the Plan or any award granted under any other plan of the General Partner or any Affiliate of the General Partner. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the General Partner, the Partnership or any of their respective Affiliates may be granted either at the same time as or at a different time from the grant of such other Awards or awards.

(ii) Limits on Transfer of Awards.

(A) Except as provided in Section 6(f)(ii)(C), each Option and UAR shall be exercisable only by the Participant during the Participant’s lifetime, or by the Person to whom the Participant’s rights shall pass by will or the laws of descent and distribution.

(B) Except as provided in Section 6(f)(ii)(C), no Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the General Partner, the Partnership or any of their respective Affiliates.

(C) The Committee may provide in an Award Agreement or in its discretion that an Award may, on such terms and conditions as the Committee may from time to time establish, be transferred by a Participant without consideration to any “family member” of the Participant, as defined in the instructions to use of the Form S-8 Registration Statement under the Securities Act of 1933, as amended, or any related family trust, limited partnership or other transferee specifically approved by the Committee.

(iii) Term of Awards. The term of each Award shall be for such period as may be determined by the Committee.

(iv) Issuance of Units. The Units or other securities of the Partnership delivered pursuant to an Award may be evidenced in any manner deemed appropriate by the Committee in its sole discretion, including, without limitation, in the form of a certificate issued in the name of the Participant or by book entry, electronic or otherwise and shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any securities exchange upon which such Units or other securities are then listed, and any applicable laws, and the Committee may cause a legend or legends to be inscribed on any certificates, if applicable, to make appropriate reference to such restrictions.

(v) Consideration for Grants. To the extent permitted by applicable law, Awards may be granted for such consideration, including services, as the Committee shall determine.

(vi) Delivery of Units or other Securities and Payment by Participant of Consideration. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Partnership shall not be required to issue or deliver any certificates or make any book entries evidencing Units pursuant to the exercise or vesting of any Award unless and until the Board or the Committee has determined, with advice of counsel, that (A) the issuance of such Units is in compliance with all applicable laws, regulations of governmental authorities, and, if applicable, the requirements of any securities exchange on which the Units are listed or traded, and (B) the Units are covered by an effective registration statement or applicable exemption from registration. In addition to the terms and conditions provided herein, the Board or the Committee may require that a Participant make such reasonable covenants, agreements, and representations as the Board or the Committee, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements. Without limiting the generality of the foregoing, the delivery of Units pursuant to the exercise or vesting of an Award may be deferred for any period during which, in the good faith determination of the Committee, the Partnership is not reasonably able to obtain or deliver Units pursuant to such Award without violating applicable law or the applicable rules or regulations of any governmental agency or authority or securities exchange. No Units or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement (including any exercise price or tax withholding) is received by the General Partner. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine,

including cash, other Awards, withholding of Units, cashless broker exercises with simultaneous sale, or any combination thereof; provided that the combined value, as determined by the Committee, of all cash and cash equivalents and the Fair Market Value of any such Units or other property so tendered to the General Partner, as of the date of such tender, is at least equal to the full amount required to be paid to the General Partner pursuant to the Plan or the applicable Award Agreement.

(vii) Change of Control. If specifically provided in an Award Agreement, upon a Change of Control the Award may automatically vest and be payable or become exercisable in full, as the case may be.

(viii) Substitute Awards. Awards may be granted under the Plan in substitution of similar awards held by individuals who are or who become Employees, Consultants or Directors in connection with a merger, consolidation or acquisition by the Partnership or one of its Affiliates of another entity or the securities or assets of another entity (including in connection with the acquisition by the Partnership or one of its Affiliates of additional securities of an entity that is an existing Affiliate of the Partnership). To the extent permitted by Section 409A, such substitute Awards that are Options or UARs may have exercise prices less than the Fair Market Value of a Unit on the date of the substitution.

(ix) Prohibition on Repricing of Options and UARs. Subject to the provisions of Section 4(c) and Section 7(c), the terms of outstanding Award Agreements may not be amended without the approval of the Partnership’s unitholders so as to:

(A) reduce the Unit exercise price of any outstanding Options or UARs,

(B) grant a new Option, UAR or other Award in substitution for, or upon the cancellation of, any previously granted Option or UAR that has the effect of reducing the exercise price thereof,

(C) exchange any Option or UAR for Units, cash, or other consideration when the exercise price per Unit under such Option or UAR exceeds the Fair Market Value of the underlying Units, or

(D) take any other action that would be considered a “repricing” of an Option or UAR under the listing standards of the New York Stock Exchange or, if the Units are not then-listed on such exchange, to the extent applicable, on any other national securities exchange on which the Units are listed.

Subject to Section 4(c), Section 7(c) and Section 8(n), the Committee shall have the authority, without the approval of the Partnership’s unitholders, to amend any outstanding Award to increase the per Unit exercise price of any outstanding Options or UARs or to cancel and replace any outstanding Options or UARs with the grant of Options or UARs having a per Unit exercise price that is equal to or greater than the per Unit exercise price of the original Options or UARs.

Section 7. Amendment and Termination. Except to the extent prohibited by applicable law:

(a) Amendments to the Plan. Except as required by applicable law or the rules of the principal securities exchange on which the Units are traded and subject to Section 7(b) below, the Board or the Committee may amend, alter, suspend, discontinue, or terminate the Plan in any manner, including increasing the number of Units available for Awards under the Plan, without the consent of any partner, Participant, other holder or beneficiary of an Award, or other Person.

(b) Amendments to Awards. Subject to Section 7(a), the Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted (including, without limitation, requiring or allowing for an election to settle an Award in cash), provided no change in any Award shall materially reduce the benefit to a Participant immediately prior to such change without the consent of such Participant.

(c) Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including the events described in Section 4(c)) affecting the Partnership or the financial statements of the Partnership, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or such Award.

Section 8. General Provisions.

(a) No Rights to Award. No Person shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Participants. The terms and conditions of Awards need not be the same with respect to each recipient.

(b) Tax Withholding. Unless other arrangements have been made that are acceptable to the General Partner or any of its Affiliates, the General Partner or any Affiliate of the General Partner is authorized to deduct, withhold, or cause to be deducted or withheld, from any Award, from any payment due or transfer made under any Award, or from any compensation or other amount owing to a Participant the amount (in cash, Units, including Units that would otherwise be issued pursuant to such Award, or other property) of any applicable taxes payable in respect of the grant or settlement of an Award, its exercise, the lapse of restrictions thereon, or any other payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the General Partner or any Affiliate of the General Partner to satisfy its withholding obligations for the payment of such taxes. In the event that Units that would otherwise be issued pursuant to an Award are used to satisfy such withholding obligations, the number of Units that may be withheld or surrendered shall be limited to the number of Units that have a Fair Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes that are applicable to such taxable income; provided, however, that such withholding may be based on rates in excess of the minimum statutory withholding rates if (x) the Committee (i) determines that such withholding would not result in adverse accounting, tax or other consequences to the General Partner or any of its Affiliates (other than immaterial administrative, reporting or similar consequences) and (ii) authorizes such withholding at such greater rates and (y) the holder of such Award consents to such withholding at such greater rates.

(c) No Right to Employment or Service Relationship. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of the General Partner or any of its Affiliates, to continue providing consulting services, or to remain on the Board, as applicable. Furthermore, the General Partner or an Affiliate of the General Partner may at any time dismiss a Participant from employment or his or her service relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan, any Award Agreement or other written agreement between any such entity and a Participant.

(d) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware without regard to its conflict of laws principles.

(e) Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person, or Award, and the remainder of the Plan and any such Award shall remain in full force and effect.

(f) Other Laws. The Committee may refuse to issue or transfer any Units or other consideration under an Award if, in its sole discretion, it determines that the issuance or transfer of such Units or such other consideration might violate any applicable law or regulation or the rules of the principal securities exchange on which the Units are then traded, or entitle the Partnership or an Affiliate of the Partnership to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the General Partner by a Participant, other holder, or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary.

(g) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the General Partner or any Affiliate of the General Partner and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the General Partner or any Affiliate of the General Partner pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the General Partner or such Affiliate.

(h) No Fractional Units. No fractional Units shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine in its sole discretion whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Units or whether such fractional Units or any rights thereto shall be canceled, terminated, or otherwise eliminated with or without consideration.

(i) Headings. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision hereof.

(j) Facility Payment. Any amounts payable hereunder to any individual under legal disability or who, in the judgment of the Committee, is unable to properly manage his financial

affairs, may be paid to the legal representative of such individual, or may be applied for the benefit of such individual in any manner that the Committee may select, and the General Partner, the Partnership and their respective Affiliates shall be relieved of any further liability for payment of such amounts.

(k) Participation by Affiliates. In making Awards to Employees employed by, or Consultants providing services to, an Affiliate of the General Partner, the Committee shall be acting on behalf of the Affiliate of the General Partner, and to the extent the Partnership has an obligation to reimburse the General Partner for compensation paid to Employees or Consultants for services rendered for the benefit of the Partnership, such reimbursement payments may be made by the Partnership directly to the Affiliate of the General Partner, and, if made to the General Partner, shall be received by the General Partner as agent for the Affiliate of the General Partner.

(l) Allocation of Costs. Nothing herein shall be deemed to override, amend, or modify any cost sharing arrangement, omnibus agreement, or other arrangement between the General Partner, the Partnership, and any of their respective Affiliates regarding the sharing of costs between such entities.

(m) Gender and Number. Words in the masculine gender shall include the feminine gender, the plural shall include the singular and the singular shall include the plural.

(n) Compliance with Section 409A. Nothing in the Plan or any Award Agreement shall operate or be construed to cause the Plan or an Award that is subject to Section 409A to fail to comply with the requirements of Section 409A. The applicable provisions of Section 409A are hereby incorporated by reference and shall control over any Plan or Award Agreement provision in conflict therewith or that would cause a failure of compliance thereunder, to the extent necessary to resolve such conflict or obviate such failure. Subject to any other restrictions or limitations contained herein, in the event that a “specified employee” (as defined under Section 409A) becomes entitled to a payment under an Award that constitutes a “deferral of compensation” (as defined under Section 409A) on account of a “separation from service” (as defined under Section 409A), to the extent required by the Code, such payment shall not occur until the date that is six months plus one day from the date of such separation from service. Any amount that is otherwise payable within the six-month period described herein will be aggregated and paid in a lump sum without interest.
