Each of ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ is sometimes referred to herein as a “Management Stockholder” and collectively, as the “Management Stockholders”, and each of ▇▇▇▇▇ and each Management Stockholder is hereinafter referred to individually as a “Party” and collectively as the “Parties.”

WHEREAS, contemporaneously with the execution and delivery hereof, Allen, Flores, ▇▇▇▇▇▇▇ and Vulcan Energy Corporation, a Delaware corporation (the “Company”), are entering into the Stockholders’ Agreement for the Company (as such agreement may be amended by the parties thereto from time to time, the “Stockholders’ Agreement”); and

WHEREAS, as a condition to the willingness of each such party to enter into the Stockholders’ Agreement, the Parties have agreed to enter into and abide by the terms of this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the Parties agree as follows:

The growth rate and hence Applicable Performance Criteria will be calculated for each Rolling Period at the end of each calendar quarter beginning with quarter ending Dec. 31, 2004 using the Rolling Period ended December 31, 2004 (but, if the Company has transferred any interest in MLP, assuming the Company’s interest is as assumed above) as the base measurement period.

ARTICLE II

COVENANTS

2.1 Midstream Opportunities.

(a) Obligation to Give Notice of Midstream Opportunities. If any Management Stockholder or any VIM Representative has actual knowledge of any bona fide Midstream Opportunity that such person reasonably believes would be considered by MLP or the Company and that such person has the right to fulfill or to direct to another Person for fulfillment, such person (the “Notifying Party”) shall promptly notify the Company, MLP (with respect to any Midstream Oil Opportunity) and the other Parties orally or in writing (including by email) of such Midstream Opportunity (such notice, the “Opportunity Notice”); provided, however, that no such person shall be required to give any such notice where doing so could reasonably be deemed to cause such person or any of its Affiliates to breach any contractual, fiduciary or other obligation owed to any Person or is reasonably likely to subject such person to a claim that such notice would breach any contractual, fiduciary or other obligation, in each case other than any obligation undertaken primarily for the purpose of enabling a Party to avoid its commitments and obligations under this Agreement. Promptly upon request by the Company, any other Party or, if applicable, MLP, the Notifying Party shall provide all relevant information regarding the Midstream Opportunity in the possession of the Notifying Party to the requesting party; provided, further, however that there shall be no obligation to notify MLP of any Midstream Opportunity that is not a Midstream Oil Opportunity. ▇▇▇▇▇ shall direct, and shall use reasonable efforts to cause, the VIM Representatives to comply with this Agreement.

(b) Exploitation of Midstream Opportunities. Except as otherwise set forth in this Article II, no Party shall, or shall cause its Controlled Affiliates to, Pursue any Midstream Opportunity; provided, however, that following compliance with the notice requirements of Section 2.1(a) and subject to Section 2.1(e), the Notifying Party may, and may cause any of its Controlled Affiliates to Pursue such Midstream Opportunity if the Company shall have elected not to Pursue such Midstream Opportunity (either directly or through a Subsidiary); provided, further, however, that if ▇▇▇▇▇ elects to Pursue such Midstream Opportunity pursuant to Section 2.1(c) below, regardless of whether ▇▇▇▇▇▇ and/or ▇▇▇▇▇▇▇ (or their designees on the board of directors of the Company) concurred in the Company’s determination not to Pursue such Midstream Opportunity, such election by ▇▇▇▇▇ shall have the effect of prohibiting any Management Stockholder from Pursuing, and from causing its respective Controlled Affiliates to Pursue, such Midstream Opportunity.

(c) ▇▇▇▇▇’▇ Exploitation Right. Notwithstanding Section 2.1(b), if the Company shall have elected not to Pursue a Midstream Opportunity (either directly or through a Subsidiary), regardless of whether ▇▇▇▇▇▇ and/or ▇▇▇▇▇▇▇ (or their designees on the board of directors of the Company) concurred in the Company’s determination not to Pursue such Midstream Opportunity, ▇▇▇▇▇ may Pursue such Midstream Opportunity (either directly or through a Subsidiary or a Controlled Affiliate) to the exclusion of the Management Stockholders, provided that ▇▇▇▇▇ complies with Section 2.3 with respect to such Midstream Opportunity.

(d) Deemed Election Not to Pursue. For purposes of Section 2.1(b), each of the Company and ▇▇▇▇▇ shall be deemed to have elected not to Pursue a Midstream Opportunity that is not a Midstream Oil Opportunity if it does not give notice to the Parties of its determination to Pursue such Midstream Opportunity (either directly or through a Subsidiary or a Controlled Affiliate) within 15 days after its receipt of the Opportunity Notice with respect to such Midstream Opportunity. In addition, if the Company or ▇▇▇▇▇ abandons its efforts to Pursue (either directly or through a Subsidiary or a Controlled Affiliate) such Midstream Opportunity, it shall be deemed to have elected not to Pursue such Midstream Opportunity at the time of such abandonment. If the Company or ▇▇▇▇▇ should abandon such efforts, it will give notice thereof to the Management Stockholders as soon as reasonably practicable.

(e) Exploitation of Midstream Oil Opportunities. No Party shall, or shall cause its Controlled Affiliates to, Pursue any Midstream Oil Opportunity other than by assisting MLP; provided, however, that notwithstanding any other provision of this Agreement to the contrary, the opportunity to acquire directly or indirectly any membership interest in MLPGP or any Security issued by any Subsidiary of MLPGP or by MLP shall not constitute a Midstream Oil Opportunity for purposes this Agreement.

2.2 Exceptions.

(a) Failure to Meet Performance Criteria. Notwithstanding anything in this Agreement to the contrary, Section 2.1 shall not apply to ▇▇▇▇▇ or any VIM Representative with respect to Midstream Opportunities that ▇▇▇▇▇ or any

VIM Representative first learned about from a source other than a Management Stockholder, other than Midstream Oil Opportunities, at any time that the Company does not meet the Applicable Performance Criteria. Without limiting the generality of the foregoing, ▇▇▇▇▇ shall not be obligated to, or to direct or cause any VIM Representative to, notify the Company or the Management Stockholders of, and ▇▇▇▇▇ shall not be prohibited from Pursuing, and ▇▇▇▇▇ shall not be prohibited from causing its Controlled Affiliates to Pursue, any Midstream Opportunity that is not a Midstream Oil Opportunity of which ▇▇▇▇▇ becomes aware during any period that the Company does not meet the Applicable Performance Criteria, regardless of whether the Company subsequently meets the Applicable Performance Criteria; provided, that ▇▇▇▇▇ first learned of such Midstream Opportunity on a nonconfidential basis from a source other than the Notifying Party; provided, further, that such source was not known by ▇▇▇▇▇ to be bound by any agreement with the Notifying Party to keep such information confidential, or otherwise prohibited from transmitting the information to ▇▇▇▇▇ by a contractual, legal or fiduciary obligation.

(b) Structured Investments. Notwithstanding anything in this Agreement to the contrary, Section 2.1 shall not apply to any Structured Investment.

(c) Insignificant Midstream Business. For the avoidance of doubt, Section 2.1 shall not apply to any Midstream Opportunity if such midstream Opportunity is with respect to a Person not having a Significant Midstream Business.

(d) Recognition of Fiduciary Obligations. Notwithstanding anything in this Agreement to the contrary and without limiting the proviso to Section 2.1(a), it is understood and acknowledged that each of the Parties has, and may continue to have, fiduciary obligations to others by virtue of his investments in, or relationships with, other companies, and notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall be deemed to require any Party to take or fail to take any action where doing so could reasonably be deemed to cause such Party or any of its Affiliates to breach any fiduciary or other similar obligation owed to any Person or is reasonably likely to subject such Party to a claim that such action or failure to act would breach any fiduciary or other similar obligation, in each case other than any obligation undertaken primarily for the purpose of enabling a Party to avoid its commitments and obligations under this Agreement.

2.3 Management Stockholders’ Participation Right.

(a) If ▇▇▇▇▇ elects to Pursue a Midstream Opportunity (either directly or through a Subsidiary) pursuant to Section 2.1(c), then ▇▇▇▇▇ shall offer each Management Stockholder the opportunity to invest in the acquisition vehicle for such transaction (with respect to each such Midstream Opportunity, an “Acquisition Company”) on the Participation Terms (as defined herein) applicable to such Midstream Opportunity. For the avoidance of doubt, neither ▇▇▇▇▇ nor the Company shall be required to offer the Participation Terms to the Management Stockholders with respect to any Midstream Opportunity exploited by or through the Company.

(b) The “Participation Terms” means, with respect to a particular Midstream Opportunity, the following terms:

(i) The participating Management Stockholders shall be required to purchase, collectively, the Minimum Participation Equity Amount of the equity of the Acquisition Company for such Midstream Opportunity on the same terms and conditions as such equity is issued to ▇▇▇▇▇ or his designee; provided, however, that each participating Management Stockholder shall also be offered the opportunity to purchase the greater of (x) its pro-rata share (based on its fully diluted percentage ownership of the Company, calculated based on the treasury method, at such time) and (y) 20%, of the initial equity in such Acquisition Company on the same terms and conditions as such equity is issued to ▇▇▇▇▇ or his designee; provided, further, that each Participating Stockholder shall be required to enter into a stockholders’ agreement with ▇▇▇▇▇ or his designee which contains terms which are substantially similar to those set forth in Articles III, IV, VI and VII of the Stockholders’ Agreement; and

(ii) Each participating Management Stockholder shall be provided the Incentive Arrangements (as defined herein) with respect to such Midstream Opportunity; provided, however, that (x) if ▇▇▇▇▇ reasonably believes in good faith that the participating Management Stockholder or Management Stockholders are not capable of, or are not willing to, manage the business and affairs of the Acquisition Company (1) in a manner that is reasonably satisfactory to ▇▇▇▇▇ and (2) on terms and conditions substantially similar to those set forth with respect to the Company in the Stockholders’ Agreement, then ▇▇▇▇▇ shall be entitled to direct the participating Management Stockholder or Management Stockholders to identify and, subject to ▇▇▇▇▇’▇ approval in his reasonable discretion, hire other individuals to act as operating management with respect to such Acquisition Company and (y) the compensation arrangements for any operating management hired pursuant to clause (x) shall (1) be acceptable to ▇▇▇▇▇ in his reasonable discretion and (2) be derived solely from the aggregate Incentive Arrangements with respect to such Midstream Opportunity, and appropriate adjustments shall be made to the terms of the Incentive Arrangements to reflect the participation of such operating management. For purposes of clause (y)(2) of the proviso to the immediately preceding sentence, in any case where there is only one participating Management Stockholder and additional operating management is hired pursuant to clause (x) of such proviso, the aggregate Incentive Arrangements shall be determined as if there were two participating Management Stockholders. For the avoidance of doubt, neither the requirement by ▇▇▇▇▇ of the hiring of operating management

nor the sharing of the Incentive Arrangements with such operating management with respect to a particular Midstream Opportunity pursuant to the proviso to the preceding sentence shall preclude ▇▇▇▇▇ from pursuing such Midstream Opportunity pursuant to Section 2.1(c).

(c) The “Incentive Arrangements” means, with respect to a particular Midstream Opportunity to which they apply, the following terms:

(i) Each participating Management Stockholder shall be granted an option to purchase an additional number of shares of common equity of the Acquisition Company for such Midstream Opportunity equal to 5% of the aggregate number of shares of common equity of the Acquisition Company issued in connection with such Midstream Opportunity, subject to Section 2.3(b)(ii). The exercise price of such option shall be the price at which such shares of common equity are issued in connection with such Midstream Opportunity, and the shares covered by such option shall vest in five equal annual installments, commencing on the first anniversary of the closing date of the consummation of the transaction that exploits such Midstream Opportunity; and

(ii) The Acquisition Company for such Midstream Opportunity shall have an obligation to make an incentive payment to each participating Management Stockholder on terms and conditions substantially similar to those set forth in the “Management Incentive Payment” provision of such participating Management Stockholder’s Employment Agreement (and the related definitions).

(d) The Parties agree to consider alternative structures that provide substantially similar economics to the Parties by using different classes of capital stock.

2.4 Cooperation. Each Party shall cooperate fully with the Company, ▇▇▇▇▇ and MLP in any evaluation or pursuit of any Midstream Opportunity presented to the Company, ▇▇▇▇▇ or MLP hereunder. Without limiting the generality of the foregoing, if any Midstream Opportunity is available only to the Notifying Party, such Party shall use reasonable efforts to cause such Midstream Opportunity to be made available to the Company, MLP and/or ▇▇▇▇▇. To the extent neither the Company nor ▇▇▇▇▇ elects to Pursue a Midstream Opportunity under Section 2.1(d) or otherwise, either or both Management Stockholders may Pursue such Midstream Opportunity. The Parties acknowledge and agree that the fact that a Midstream Opportunity may only be available to the Notifying Party shall not affect the applicability of this Article II to such Midstream Opportunity.

2.5 Remedies. Each Party recognizes that a breach by it of this Article II will result in irreparable damage and harm to each of the other Parties and its

respective Affiliates and that each of the other Parties and its respective Affiliates may be without an adequate remedy at law in the event of any such activities. Each Party agrees, therefore, if any provision of Article II is breached, then each of the non-breaching Parties and its Affiliates may at its election institute and prosecute proceedings in any court of competent jurisdiction: (a) to obtain specific performance by the breaching Party of Article II; (b) to enjoin the breaching Party from engaging in the activities proscribed by Article II; or (c) to pursue any one or more of the foregoing or any other remedy available to it under applicable law, including actual damages. Any non-breaching Party and its respective Affiliates will not, by seeking or obtaining such relief, be deemed to have precluded themselves from obtaining any other relief to which they may be entitled. Each of the Parties hereby waives any requirement that the non-breaching Parties or their respective Affiliates post any bond or other security in connection with the enforcement of this Agreement.

2.6 Restricted Business Procedures. If any Management Stockholder, ▇▇▇▇▇ or the Company or any of the Company’s Subsidiaries acquires a Midstream Business that is not a Midstream Oil Business but includes Midstream Oil Assets valued in excess of $10 million as of the date of acquisition, as determined in good faith by the Company’s board of directors (such Midstream Oil Assets, a “Restricted Business”), then not later than 30 days after the consummation of the acquisition by such Person (the “Oil Assets Purchaser”) of the Midstream Business, the Oil Assets Purchaser shall notify MLP of such purchase and offer MLP (or cause an offer to be made to MLP of) the opportunity to purchase such Restricted Business. If within 30 days after receipt of such notification, MLP fails to notify the Oil Assets Purchaser of its intentions with respect to the Restricted Business, all rights under this Section 2.6 with respect to such Restricted Business will terminate and the Oil Assets Purchaser may continue to own and operate such Restricted Business. For the avoidance of doubt, the provisions of this Section 2.6 shall not apply to any Structured Investment. If MLP notifies the Oil Assets Purchaser that MLP has elected to purchase such Restricted Business, then the following procedures shall be followed:

(a) The Oil Assets Purchaser shall submit a good faith offer to MLP to sell the Restricted Business (the “Offer”) to MLP on the terms and for the consideration stated in the Offer.

(b) The Oil Assets Purchaser and MLP shall negotiate in good faith, for 60 days after receipt of such Offer by the MLP, the terms on which the Restricted Business will be sold to MLP. The Oil Assets Purchaser shall provide all information concerning the business, operations and finances of such Restricted Business as MLP may reasonably request.

(i) If the Oil Assets Purchaser and the MLP agree on such terms within 60 days after receipt by the MLP of the Offer, MLP shall purchase the Restricted Business on such terms as soon as commercially practicable after such agreement has been reached.

(ii) If the Oil Assets Purchaser and the MLP are unable to agree on the terms of a sale during such 60-day period, the Oil Assets Purchaser shall attempt to sell the Restricted Business to a Person that is not an Affiliate of the Oil Assets Purchaser (a “NonAffiliate Purchaser”) within nine months of the termination of such 60-day period. Any such sale to a NonAffiliate Purchaser must be for a purchase price, as determined in good faith by the Company’s board of directors, not less than 95% of the purchase price last offered by MLP.

(c) If, after the expiration of such nine-month period, the Oil Assets Purchaser has not sold the Restricted Business to a NonAffiliate Purchaser, it shall submit another Offer (the “Second Offer”) to MLP within seven days after the expiration of such nine-month period. The Oil Assets Purchaser shall provide all information concerning the business, operations and finances of such Restricted Business as may be reasonably requested by MLP.

(i) If MLP elects not to negotiate with the Oil Assets Purchaser regarding the Second Offer, the Oil Assets Purchaser shall be free to continue to engage in such Restricted Business.

(ii) If MLP elects to purchase such Restricted Business, then MLP and the Oil Assets Purchaser shall negotiate the terms of such purchase for 60 days. If the Oil Assets Purchaser and MLP agree on such terms within 60 days after receipt by MLP of the Second Offer, MLP shall purchase the Restricted Business on such terms as soon as commercially practicable after such agreement has been reached.

(iii) If during such 60-day period, no agreement has been reached between the Oil Assets Purchaser and MLP, the Oil Assets Purchaser and MLP will engage an independent investment banking firm with a national reputation to determine the value of the Restricted Business. Such investment banking firm will determine the value of the Restricted Business within 30 days and furnish the Oil Assets Purchaser and MLP its opinion of such value. The Oil Assets Purchaser and MLP will each pay one-half of the fees and expenses of such investment banking firm. Upon receipt of such opinion, the MLP shall have the option to (A) purchase the Restricted Business for an amount equal to the value determined by such investment banking firm or (B) decline to purchase such Restricted Business, in which event the Oil Assets Purchaser will be free to continue to engage in such Restricted Business.

(d) MLP may not avail itself of its rights under this Section 2.6 unless it executes (and the Oil Assets Purchaser would also be required to execute) a confidentiality agreement having the following provisions.

(i) each shall acknowledge that it, its Affiliates and its and its Affiliates’ employees, agents, advisors or representatives (collectively, “representatives”) possess and may thereafter obtain, confidential business, commercial, technical, financial and operational information from the other parties to such agreement, their respective Affiliates and their respective businesses and which relates to the past, ongoing or future operations of the Restricted Business and the Oil Assets Purchaser’s business and operations (collectively, such information, whether obtained in written form, visually (such as by inspection) or orally, is hereinafter referred to as “Confidential Information”). For purposes of such agreement, the “Confidential Information of a party” would include the Confidential Information of such Person’s Affiliates. With respect to such Confidential Information, each of the Oil Assets Purchaser and MLP would covenant to the other as follows:

(ii) Each party would agree to exercise the same degree of care as it uses in protecting its own Confidential Information from disclosure (but not less than reasonable care), to make no disclosure of any Confidential Information received from any other party, and would further agree to make no use of any Confidential Information received from any other party except, in each case, in connection with the transactions contemplated by the potential transfer of the Restricted Business. Notwithstanding the foregoing, to the extent required by law, any such parties (and each representative of such parties) would be permitted to disclose to any and all Persons, without limitation of any kind, the tax treatment and any facts that may be relevant to the tax structure of any such transaction, provided, however, that no such party (and no employee, representative, or other agent thereof) would be entitled to disclose any other information that is not relevant to understanding the tax treatment and tax structure of the transaction (including the identity of any party and any information that could lead another to determine the identity of any party), or any other information to the extent that such disclosure could result in a violation of any federal or state securities law.

(iii) The obligations of non-disclosure and restricted use contained in such agreement would not apply to any of the disclosing party’s Confidential Information that:

(1) was available to the public prior to the date such Confidential Information was disclosed to the receiving party;

(2) became available to the public through no fault of the receiving party subsequent to the date such Confidential Information was disclosed to the receiving party;

(3) was in the possession of the receiving party prior to the date such Confidential Information was disclosed to the receiving party, and was not obtained by the receiving party from a third party having an obligation of confidentiality to the disclosing party regarding such Confidential Information;

(4) was hereafter rightfully obtained by the receiving party from a third party not under an obligation of confidentiality to the disclosing party regarding such Confidential Information; or

(5) was independently developed by employees of the receiving party without using the Confidential Information of the disclosing party.

It would not be a breach of the obligation of non-disclosure contained in such agreement if a receiving party disclosed any Confidential Information as required by law or judicial proceeding; provided, however, that such disclosure would be excused only to the extent such disclosure was required by law or such proceeding and only if, to the extent reasonably practicable, the receiving party provided prior written notice to the disclosing party sufficient to allow the disclosing party an opportunity to oppose or attempt to limit the required disclosure, and only if the receiving party itself used reasonable efforts to ensure that the confidentiality of the Confidential Information is protected by court or administrative order at no cost to such receiving party.

(i) Each party would have the right to disclose to its Affiliates and representatives (collectively, its “Permitted Receiving Persons”) all Confidential Information received under such agreement; however each receiving party would warrant that its Permitted Receiving Persons would comply with all of the obligations set out in such agreement, and would further agree to be responsible for all harm caused by any non-compliance by any Permitted Receiving Person of the receiving party with any of the obligations set out in such agreement, to the same extent the receiving party would have been responsible under applicable law for its own breach of the same obligations.

(ii) Each party would agree to use reasonable efforts to inform all of its Permitted Receiving Persons to whom Confidential Information of any other party is disclosed, of the existence of such agreement and of the confidential nature of such Confidential Information.
