CONTRIBUTION AGREEMENT

This CONTRIBUTION AGREEMENT (this “Agreement”) dated December 10, 2007 is by and among Regency Energy Partners LP, a Delaware limited partnership (the “Partnership”), Regency Gas Services LP, a Delaware limited partnership (“Buyer”) and a wholly owned subsidiary of the Partnership, on the one hand, and ASC Hugoton LLC, a Delaware limited liability company (“ASC”), FrontStreet EnergyOne LLC, a Delaware limited liability company (“EnergyOne” and, together with “ASC”, each a “Seller” and collectively the “Sellers”), and, solely for purposes of Section 2.3(g) hereof, Aircraft Services Corporation (“Parent”), on the other.

RECITALS

Buyer desires to acquire, EnergyOne desires to sell and ASC desires to contribute to Buyer, the Interests for the consideration set forth below, subject to the terms and conditions of this Agreement.

NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

1.4 Other Terms. Other terms may be defined elsewhere in the text of this Agreement and shall have the meaning indicated throughout this Agreement.

ARTICLE 2
THE TRANSACTION

2.1 The Transaction. Subject to and upon the terms and conditions of this Agreement, at the Closing, each Seller shall sell or contribute, as the case may be, transfer, convey, assign and deliver to Buyer, and Buyer shall accept and acquire from each Seller, all of such Seller’s Equity Interest in the Company, including all of such Seller’s Interests, free and clear of all Liens. The Interests to be acquired by Buyer at Closing shall constitute all of the outstanding Equity Interests in the Company. At the Closing, each Seller shall deliver to Buyer assignments duly executed by such Seller transferring and assigning the Interests to Buyer in accordance with the terms of this Agreement.

2.2 Consideration.

(a) At the Closing:

(i) the Buyer shall pay to EnergyOne, by wire transfer of immediately available funds to the account designated in writing by EnergyOne to Buyer at least two Business Days prior to Closing, an amount in Cash equal to the Cash Amount;

(ii) the Partnership shall issue to ASC the Transaction Units, free and clear of all Liens (except for such restrictions as may exist under the Partnership Agreement, the Lock-Up Agreement or applicable securities laws, and Liens created by ASC), on original issue and evidenced by a certificate or certificates duly executed and delivered by or on behalf of the Partnership; and

(iii) to the extent unpaid, the Buyer shall pay to the payees of any Expenses by wire transfer of immediately available funds to the account(s) designated by such Persons in the applicable Payoff Letters, the amounts specified in the Payoff Letters less, to the extent applicable, any Medicaid, Social Security, income tax, unemployment tax and other amounts required to be withheld.

(b) Promptly after the Closing, Buyer shall pay to each holder of any Third-Party Debt, by wire transfer of immediately available funds to the account(s) designated by such Persons in the applicable Debt Payoff Letters, the amounts specified in the Debt Payoff Letters.

2.3 Purchase Price Adjustments.

(a) Preparation of Estimated Closing Statement. The Company shall prepare in good faith and deliver to Buyer, at least four Business Days prior to the Closing Date and at the sole expense of the Company, a statement as of the Closing Date (the “Estimated Closing

Statement”), setting forth (i) a detailed determination of Estimated Net Working Capital and Estimated Capital Expenditure Adjustment Amount and (ii) based on such Estimated Net Working Capital and Estimated Capital Expenditure Adjustment Amount, the Estimated Aggregate Consideration Adjustment Amount, if any, and the number of Transaction Units. The Expenses and the Debt Payoff Amount to be used in the calculation of Estimated Net Working Capital shall be based on amounts set forth in the Payoff Letters, or, to the extent a Payoff Letter has not been provided therefor, the Company’s good faith estimate of such amounts, and in each case, shall be subject to final determination in the preparation of the Final Closing Statement. Each estimation shall be made as of 11:59 p.m. on the Measurement Date. If Buyer has any questions or disagreements regarding the Estimated Closing Statement, Buyer shall contact the Sellers at least two Business Days prior to the Closing Date, and in such case the Sellers and Buyer shall in good faith attempt to resolve any disagreements. If Buyer and the Sellers agree on changes to the Company’s proposed Estimated Net Working Capital, the Company’s proposed Estimated Capital Expenditure Adjustment Amount, Estimated Aggregate Consideration Adjustment Amount or the Company’s calculation of the number of Transaction Units based on such discussions, then the number of Transaction Units to be issued at Closing shall be based on such changes. If Buyer and Sellers do not agree on changes to such amounts, then such amounts shall be paid at the Closing based on the amounts set forth in the Estimated Closing Statement. In either such case, appropriate adjustments to the Purchase Price shall be made after the Closing pursuant to Sections 2.3(a), 2.3(b), and 2.3(c).

(b) Preparation of Closing Statement. As soon as reasonably practicable after the Closing Date (and, in any event, within 90 days after the Closing Date), Buyer shall prepare and deliver to Sellers, at the sole expense of Buyer, a closing statement as of 11:59 p.m. on the Measurement Date (the “Proposed Closing Statement”), setting forth the proposed final calculation of Net Working Capital, the Capital Expenditure Adjustment Amount and the Aggregate Consideration Adjustment Amount. Buyer shall provide Sellers access to the Records in accordance with Section 6.4 in order to confirm Buyer’s calculations. If Buyer fails to deliver to Sellers a Proposed Closing Statement within the allowed time periods, then the Estimated Closing Statement shall be deemed to be the Final Closing Statement for purposes of this Agreement.

(c) Examination of Proposed Closing Statement. Sellers shall review the Proposed Closing Statement to confirm the accuracy of the Proposed Closing Statement and Buyer’s calculations. If Sellers fail to give Buyer written notice of any disputed amounts within 30 days after Sellers receive the Proposed Closing Statement (the “Review Period”), then the Proposed Closing Statement shall become the Final Closing Statement for purposes hereof. If Sellers give Buyer written notice of any disputed items within the Review Period, Buyer and Sellers shall attempt in good faith to agree on any adjustments that should be made to the Proposed Closing Statement. If Buyer and Sellers fail to resolve any disputed amounts within 60 days after Sellers receive the Proposed Closing Statement, Buyer and Sellers will engage the Audit Firm to resolve any such disputed matters in accordance with the terms of this Agreement, and, in connection with such engagement Buyer, the Company and Sellers shall execute any engagement, indemnity and other agreements as the Audit Firm may require as a condition to such engagement. The Audit Firm’s engagement shall be limited to the resolution of disputed amounts set forth in the Proposed Closing Statement that have been identified by Sellers, and no other matter relating to the Final Closing Statement shall be subject to determination by the

Audit Firm except to the extent affected by resolution of the disputed amounts. The Parties shall cooperate diligently with any reasonable request of the Audit Firm in an effort to resolve any disputed matter as soon as reasonably possible after the Audit Firm is engaged. If possible, the decision of the Audit Firm shall be made within 30 days after being engaged and shall be final and binding on the Parties. The Proposed Closing Statement shall be revised, if necessary, to reflect the final determination of Net Working Capital (the final form of the Proposed Closing Statement, including any revisions that are made thereto pursuant to this Section 2.3(b), is referred to herein as the “Final Closing Statement”).

(d) Adjustments.

(i) If the Aggregate Consideration Adjustment Amount as reflected on the Final Closing Statement is less than the Estimated Aggregate Consideration Adjustment Amount (the amount of such shortfall, if any, being hereinafter referred to as the “Aggregate Consideration Deficit”), each Seller shall transfer to the Partnership Cash (in the case of EnergyOne) or Transaction Units (in the case of ASC) with a value equal its Pro Rata Share of the Aggregate Consideration Deficit within five Business Days after the final determination of the Final Closing Statement. The number of Transaction Units to be transferred by ASC shall be (A) (i) ASC’s Pro Rata Share of the Aggregate Consideration Deficit multiplied by 25% divided by (ii) $28.729, plus (B) (i) ASC’s Pro Rata Share of the Aggregate Consideration Deficit multiplied by 75% divided by (ii) $26.952.

(ii) If the Aggregate Consideration Adjustment Amount as reflected on the Final Closing Statement is greater than the Estimated Aggregate Consideration Adjustment Amount (the amount of such excess being hereinafter referred to as the “Aggregate Consideration Surplus”), Buyer shall pay each Seller an amount in Cash equal to its Pro Rata Share of the Aggregate Consideration Surplus within five Business Days after the final determination of the Final Closing Statement.

(e) No Duplicative Effect. The provisions of this Section 2.3 and of any other Transaction Document shall apply in such a manner so as not to give the components and calculations duplicative effect to any item of adjustment and, except as otherwise expressly provided in this Agreement or as described in the Sample Balance Sheet, the Parties covenant and agree that no amount shall be (or is intended to be) included, in whole or in part (either as an increase or reduction) more than once in the calculation of (including any component of) Net Working Capital, Capital Expenditure Adjustment Amount or the number of Transaction Units, or any other calculated amount pursuant to this Agreement if the effect of such additional inclusion (either as an increase or reduction) would be to cause such amount to be overstated or understated for purposes of such calculation. The Parties acknowledge and agree that, if there is a conflict between a determination, calculation or methodology set forth in the Sample Balance Sheet or the definitions contained in this Agreement, as applicable, on the one hand, and those provided by GAAP, on the other hand, (i) the determination, calculation or methodology set forth in the Sample Balance Sheet or the definitions contained in this Agreement, as applicable, shall control to the extent that the matter is included in the Sample Balance Sheet or the definitions contained in this Agreement, as applicable, as a line item or specific adjustment and (ii) the determination, calculation or methodology prescribed by GAAP shall control to the extent the matter is not so addressed in the Sample Balance Sheet or the definitions contained in

this Agreement, as applicable, or requires reclassification as an asset or liability to be included in a line item or specific adjustment.

(f) Fees and Expenses of the Audit Firm. If the Parties submit any disputed amounts to the Audit Firm for resolution as provided in Section 2.3(c) above, the fees and expenses of the Audit Firm (the “Audit Fees”) will be paid by and apportioned between Buyer and Sellers based on the aggregate dollar amount of the amount in dispute and inversely related to the relative recovery as determined by the Audit Firm of Sellers and Buyer, respectively. For example, if the aggregate dollar amount of the amount in dispute is $1,000,000 and the relative recovery of Sellers and Buyer as determined by the Audit Firm is $900,000 and $100,000, respectively, then Buyer will be apportioned 90% of the Audit Fees and Sellers will be apportioned 10% of the Audit Fees. Sellers and Buyer shall promptly, and in any event within five Business Days after the final determination of the Final Closing Statement, pay to the Audit Firm the amount of Audit Fees payable by Sellers and Buyer pursuant to this Section (with each Seller paying its Pro Rata Share of any such Audit Fees payable by the Sellers).

(g) Performance. To provide assurance to the Partnership and Buyer of the performance of ASC’s obligations under Section 2.3(c), Section 2.3(e) and Article 10, until the first anniversary of the Closing Date (the “Indemnification Period”), Parent agrees to cause ASC to perform its obligations under Section 2.3(c), Section 2.3(e) and Article 10 hereof; provided, that Parent’s liability under this Section 2.3(g) shall not exceed the aggregate amount of $14,250,000. Notwithstanding the foregoing, if a Claim Notice is provided in accordance with Article 10 prior to the first anniversary of the Closing Date and shall not have been finally resolved as of the end of the Indemnification Period (by final, nonappealable judgment or settlement), then Parent shall continue to cause ASC to perform its obligations with respect to such Claim Notice until the resolution of such claim by final, nonappealable judgment or settlement.

2.4 Anti-Dilution Adjustments. If the Partnership changes (or the Partnership sets a related record date that will occur before the Closing Date for a change in) the number or kind of Common Units outstanding by way of a unit split, reverse unit split, unit dividend, recapitalization, reclassification, reorganization, consolidation, extraordinary or special dividend or distribution with respect to Common Units (which, for the avoidance of doubt, shall not include regular, quarterly cash distributions by the Partnership), or similar transaction, then the number of Transaction Units will be adjusted appropriately to account for such change.

ARTICLE 3
REPRESENTATIONS AND WARRANTIES CONCERNING THE SELLERS

Subject to the limitations set forth in Article 10 and except for the representations and warranties set forth in Section 3.5 and Section 3.6, which are several representations and warranties of ASC only, each Seller, severally and not jointly, represents and warrants to the Partnership and Buyer as follows (such representations and warranties being deemed to be made as of the date hereof and on a continuous basis until the Closing) except as set forth in the Disclosure Schedule (each reference in the Disclosure Schedule qualifies the referenced representation and warranty contained in this Agreement to the extent specified in the Disclosure Schedule and such other representations and warranties contained herein to the extent a matter in

the Disclosure Schedule is disclosed in such a way as to make its relevance to the information called for by such other representation and warranty readily apparent on its face):

3.1 Organization, Good Standing and Authority of Seller.

(a) Such Seller is a limited liability company duly formed, validly existing and in good standing under the laws of its jurisdiction of formation and has all requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted.

(b) Such Seller has the requisite power and authority to enter into this Agreement and the Transaction Documents to which it shall be a party and to transfer, convey and sell to Buyer at the Closing the Interests owned by it. The execution, delivery and performance of this Agreement and the other Transaction Documents to which such Seller is or is intended to be a party have been duly authorized by all requisite limited liability company action on the part of such Seller. This Agreement and the other Transaction Documents to which such Seller is or shall be a party have been or will be duly executed and delivered by such Seller, and (assuming due authorization, execution and delivery hereof and thereof by the other parties hereto and thereto) such Transaction Documents constitute or, if not yet executed, will at Closing constitute, legal, valid and binding obligations of such Seller, enforceable against such Seller in accordance with their terms, subject, as to enforceability, to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

3.2 Title to Interests. As of the date hereof, such Seller has good and valid record and beneficial title to Interests as set forth on Exhibit D, free and clear of any and all Liens, and such Interests constitute all of the Equity Interests of the Company held of record or beneficially by such Seller. Immediately prior to the Closing, such Seller shall have good and valid record and beneficial title to such Interests, free and clear of any Liens, and such Interests shall constitute all of the Equity Interests of the Company held of record or beneficially by such Seller. Upon the Closing, Buyer will acquire good title to all of the Equity Interests of the Company, free and clear of any Liens, other than any Liens created by Buyer. Neither such Seller nor the Company is a party to (a) any option, warrant, purchase right or other Contract (other than this Agreement) that could require such Seller or, after the Closing, Buyer, to sell, transfer or otherwise dispose of any Equity Interest of the Company or (b) any voting trust, proxy or other agreement or understanding with respect to the voting of any Equity Interest of the Company. As of the Closing, except for such Seller’s Pro Rata Share of the Interests, such Seller will not own any Equity Interests of the Company.

3.3 No Conflicts. Neither the execution and delivery by such Seller of this Agreement, any other Transaction Documents to which such Seller is or shall be a party or any instrument required hereby or thereby to be executed and delivered by it at Closing nor the performance by such Seller of its obligations hereunder or thereunder will require any consent under, conflict with, violate or breach the terms of, cause a default (with or without notice or lapse of time or both) or give rise to a right of termination, cancellation or acceleration of any obligation or to the loss of a benefit under, or result in the creation of any Lien on any of such

Seller’s Interests under (i) the Organizational Documents of such Seller, (ii) any Contract or other instrument to which such Seller is a party or by which it or any of its properties or assets are bound, or (iii) assuming the consents, approvals, authorizations or permits and filings or notifications referred to in Section 3.4 are duly and timely obtained, any Law, Regulation or Order applicable to such Seller, other than, in the case of clauses (ii) or (iii), any such conflicts, violations, breaches, defaults, rights, Liens or detriments that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect on the such Seller.

3.4 Consents. Except for (a) Post Closing Notifications, (b) any Notifications set forth in Section 3.4(b) of the Disclosure Schedule (the “Required Notifications”), (c) any Third-Party Consent set forth in Section 3.4(c) of the Disclosure Schedule (a “Required Third-Party Consent”), (d) any Authorizations set forth in Section 3.4(d) of the Disclosure Schedule (a “Required Authorization”), and (e) filings under the HSR Act, no Authorization, Notification or Third-Party Consent is necessary for such Seller to execute, deliver and perform this Agreement and the other Transaction Documents to which such Seller is or shall be a party, other than such Authorizations, Notifications, and Third-Party Consents that the failure to obtain or make could not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect on the Company.

3.5 Investor Status.

(a) The Transaction Units are being acquired by ASC for investment purposes only, for ASC’s own account and not as nominee or agent for any other Person or entity, and not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act. ASC is not a party to or bound by, and does not intend or have any plans to enter into, any Contract with any Person to sell, transfer or pledge any part of the Transaction Units, except for bona fide pledges or sales or transfers made in compliance with all applicable securities laws.

(b) In connection with the acquisition of the Transaction Units hereunder, ASC has had the opportunity to examine all aspects of the Partnership, its operations, and its financial condition that ASC has deemed relevant, and has had access to all information with respect to the Partnership and its business in order to make an evaluation thereof. In connection with the acquisition of the Transaction Units hereunder, ASC has had the opportunity to ask such questions of and receive answers from directors, officers, employees and representatives of the Managing General Partner concerning the Partnership and to obtain such additional information about the Partnership as ASC deems necessary for an evaluation thereof. The investment decision of ASC to acquire the Transaction Units has been based solely upon the evaluation made by ASC of the Partnership. In evaluating the suitability of an investment in the Partnership, ASC has not been furnished and has not relied upon any representations or other information (whether oral or written) other than as contained in the representations and warranties of the Partnership and the Buyer in this Agreement.

(c) ASC acknowledges that copies have been made available to it, sufficiently in advance of this Agreement as ASC deems necessary to evaluate an investment in the Transaction Units, of each of the Partnership SEC Documents, and has been informed that copies

of Exhibits to each of the Partnership SEC Documents will be made available to it upon such ASC’s written request.

(d) ASC is an “Accredited Investor” as defined in Rule 501 of Regulation D under the Securities Act.

3.6 Status of Transaction Units; Disposition.

(a) ASC acknowledges that no registration statement relating to the Transaction Units has been filed under the Securities Act or any state securities law and that, consequently, the Transaction Units are “restricted securities” within the meaning of Rule 144 under the Securities Act, may not be sold, pledged, hypothecated or otherwise transferred (and, therefore, must be held by ASC) unless the Transaction Units subsequently are registered under the Securities Act and such state laws or until an exemption from such registration requirements is available.

(b) Neither ASC nor anyone acting on ASC’s behalf has offered or sold or will offer or sell any of the Transaction Units by means that would render the disposition of the Transaction Units a violation of Section 5 of the Securities Act or any state or other applicable securities law.

ARTICLE 4
REPRESENTATIONS AND WARRANTIES CONCERNING THE COMPANY

Subject to the limitations set forth in Article 10, Sellers jointly and severally represent and warrant to Buyer as follows (such representations and warranties being deemed to be made as of the date hereof and on a continuous basis until the Closing) except as set forth in the Disclosure Schedule (each reference in the Disclosure Schedule qualifies the referenced representation and warranty contained in this Agreement to the extent specified in the Disclosure Schedule and such other representations and warranties contained herein to the extent a matter in the Disclosure Schedule is disclosed in such a way as to make its relevance to the information called for by such other representation and warranty readily apparent on its face):

4.1 Organization, Good Standing, Authority, Capitalization of FrontStreet Companies.

(a) The Company is a limited liability company duly formed, validly existing and in good standing under the Laws of the State of Delaware and has all requisite limited liability company power and authority to carry on its business as it is now being conducted and to own, operate and lease the assets it now owns, operates or holds under lease. The Company is duly qualified to transact business and is in good standing in Kansas, which is the only jurisdiction in which the business it is conducting, or the operation, ownership or leasing of its properties, makes such qualification necessary.

(b) The Interests constitute 100% of the outstanding Equity Interests of the Company. All of the Interests have been duly authorized and validly issued and were not issued in violation of any preemptive rights or other preferential rights of subscription or purchase of

any Person. The Company is not obligated, under any Contract or otherwise, to issue any Equity Interests or Equity Interest Equivalents.

(c) WGP-KHC is the only Subsidiary of the Company. WGP-KHC is duly organized as a limited liability company, validly existing and in good standing under the Laws of the State of Delaware and is duly qualified to do business as a foreign limited liability company in good standing to conduct business in the States of Kansas, which is the only jurisdiction in which the business it is conducting, or the operation, ownership or leasing of its properties, makes such qualification necessary. WGP-KHC has the requisite power and authority (as a corporation, limited partnership or limited liability company) to carry on its business as it is now being conducted and to own, operate and lease the assets it now owns, operates or holds under lease.

(d) All the outstanding membership interests in WGP-KHC (i) have been duly authorized and validly issued and are fully paid and non assessable, (ii) were not issued in violation of any preemptive rights or other preferential rights of subscription or purchase of any Person and (iii) are owned of record and beneficially by the Company, free and clear of all Liens. WGP-KHC does not have any outstanding Equity Interests Equivalents and is not obligated, under any Contract or otherwise, to issue any Equity Interests or Equity Interest Equivalents.

(e) WGP-KHC is the only Person in which the Company owns, directly or indirectly, an Equity Interest. The Company does not have any Joint Venture Entities.

(f) Sellers have heretofore provided to Buyer true and complete copies of the Organizational Documents of each of the Company and WGP-KHC.

4.2 Natural Gas Regulation. To Sellers’ Knowledge, neither FrontStreet Company has engaged in any activities that would subject either FrontStreet Company, its activities, or its facilities to the NGA jurisdiction of the FERC. To Sellers’ Knowledge, all of the facilities of the FrontStreet Companies used to transport natural gas are intrastate pipelines or “gathering” facilities and, as such, are not subject to regulation by any Governmental Authority under the NGA or the NGPA. To Sellers’ Knowledge, (i) the representations made by Sellers concerning the jurisdictional status of the FrontStreet Companies’ facilities and operations to natural gas purchasers and interstate or intrastate pipelines in order to effect sales or to facilitate transportation transactions (whether for either FrontStreet Company or any Third Person) are, and were when made, true and correct in all material respects, and (ii) the FrontStreet Companies have complied in all material respects with the terms and conditions of such sales, transportation or interconnect or similar arrangements (including “on behalf of” certificates).

4.3 Authorizations. To Sellers’ Knowledge, each FrontStreet Company possesses all material Authorizations, including all certificates of public convenience and necessity and rate authorizations required by the Governmental Authority of each state with jurisdiction over such matters, as are necessary to carry on its businesses as currently conducted. To Sellers’ Knowledge, such Authorizations are in full force and effect and have not been violated in any material respect and no suspension, revocation or cancellation thereof has been threatened.

6.12 Transaction Units.

(a) ASC agrees that the Transaction Units shall not be offered for sale, sold, assigned, pledged, hypothecated, transferred, exchanged or otherwise disposed of (a “transfer”) unless the offer and sale is registered under the Securities Act and applicable state securities laws or an exemption from such registration is available and complied with, and that if any such transfer or offer thereof, is proposed to be effected pursuant to any such exemption, then the holder of the Transaction Units must, prior to such transfer, furnish to the Partnership and the transfer agent such certifications, legal opinions or other information as they may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act or any state or foreign securities law.

(b) ASC acknowledges the following:

(i) The following legend may be placed on the certificates representing the Transaction Units:

THE UNITS (THE “UNITS”) EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES THAT IT WILL NOT DISTRIBUTE, OFFER, RESELL, PLEDGE OR OTHERWISE TRANSFER (INDIVIDUALLY AND COLLECTIVELY, A “TRANSFER”) THE UNITS EVIDENCED HEREBY, EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (B) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT SUCH AS THE EXEMPTION SET FORTH IN RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE). IF THE PROPOSED TRANSFER IS TO BE MADE OTHER

THAN PURSUANT TO CLAUSE (A) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE ISSUER AND THE TRANSFER AGENT SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR ANY STATE OR FOREIGN SECURITIES LAW.

The legend set forth above may be removed if and when the Transaction Units represented by such certificate are disposed of pursuant to an effective registration statement under the Securities Act, the opinion of counsel referred to above has been provided to the Partnership, or, in the opinion of counsel to the Partnership, the same are no longer required under the applicable requirements of such securities laws. The unit certificates shall also bear any additional legends required by applicable federal, state or foreign securities laws, which legends may be removed when, in the opinion of counsel to the Partnership, the same are no longer required under the applicable requirements of such securities laws.

(ii) Stop transfer instructions have been or will be placed with respect to the Transaction Units so as to restrict the distribution, resale, pledge, hypothecation or other transfer thereof in accordance with this Agreement.

(iii) The legend and stop transfer instructions described in subparagraphs (i) and (ii) above will be replaced with respect to any new certificate issued upon presentment by the undersigned of a certificate for transfer.

(c) ASC is aware that the Partnership has relied on the representations and warranties of ASC set forth in Article 3 and on the covenants of ASC set forth in this Section 6.12 in determining that an exemption from registration under the Securities Act, applicable state securities laws and the rules promulgated thereunder is available for the issuance of the Transaction Units by the Partnership to ASC, and that, but for such representations, no issuance of the Transaction Units would be made by the Partnership to ASC pursuant to this Agreement.

6.13 FCC Filings.

(b) Buyer and Sellers shall furnish to each other such necessary information and reasonable assistance as the other may reasonably request in connection with the preparation, filing and prosecution of the FCC Transfer Applications.

prosecute the FCC Transfer Applications and shall furnish to the FCC any documents, materials, or other information reasonably requested by the FCC.

(i) the Buyer Indemnitees, collectively, or the Seller Indemnitees, collectively, shall have suffered or incurred aggregate Losses otherwise recoverable under this Article 10 in an amount in excess of the Deductible, and then recovery shall be permitted only to the extent such Losses exceed $500,000 (i.e., $500,000 of the Deductible shall be recoverable); and

(ii) after the Deductible has been met, the Buyer Indemnitees, collectively, or the Seller Indemnitees, collectively, shall have suffered or incurred Losses with respect to the individual Claim or series of related Claims that arise out of substantially the same facts and circumstances for which recovery is sought in excess of $50,000, in which case the full amount of such Losses shall be recoverable, subject to the limitations imposed by the other provisions of this Section 10.4.

Notwithstanding the foregoing, any claim for indemnification (and the Losses recoverable therefrom) that may be brought under both (A) Section 10.3(b)(i) and/or Section 10.3(b)(iii), on the one hand, and (B) any other subsection of Section 10.3, on the other hand, shall not be subject to any limitation specified in this Section 10.4(e).

(i) For purposes of determining whether a representation or warranty contained herein, other than those set forth in Sections 4.12, 4.16, 5.3 and 5.4, has been breached for purposes of this Article 10 and determining the amount of Losses suffered thereby by any Buyer Indemnitee or Seller Indemnitee, as the case may be, each representation and warranty set forth in this Agreement (other than as aforesaid), and any qualification with respect to any such representation or warranty set forth in the Disclosure Schedule in the case of representations or

warranties by Sellers, shall be read without regard or giving effect to any “material,” “materiality,” “Material Adverse Effect,” and “substantial” qualifications that may be contained in any such representation or warranty; provided, however, that the defined term “Material Contract” and all “material,” “materiality,” “Material Adverse Effect,” and “substantial” qualifications that are contained in any defined term shall be given effect;

(ii) No investigation or knowledge of any Party, whenever undertaken or however obtained, shall limit such Party’s right to indemnification hereunder in any manner; and

(iii) The provisions of this Article 10 shall apply in such a manner as not to give duplicative effect to any item of adjustment and if there has been an adjustment to the Aggregate Consideration for any Loss, there shall not be any charge against the Deductible and no Indemnitee may claim a breach of any representation or warranty with respect to any Loss that gave rise to such adjustment in the Aggregate Consideration pursuant to Section 2.3 to the extent of the amount of such Loss given effect in such adjustment to the Aggregate Consideration.

(g) The amount of Losses required to be paid pursuant to this Article 10 shall be reduced to the extent of any tax benefits actually realized, or insurance proceeds directly or indirectly received by the Indemnified Party.

(b) If any Claim is asserted against or any Loss is sought to be collected from an Indemnifying Party, the Indemnified Party shall with reasonable promptness (and in any event prior to the expiration of the relevant survival period set forth in Section 10.1(a)) provide to the Indemnifying Party a Claim Notice. The failure to notify the Indemnifying Party shall not relieve it of any liability that it may have to any Indemnified Party with respect to such Claim or Loss except to the extent the Indemnifying Party shall have been prejudiced by such failure or to the extent the Claim Notice was provided after the expiration of the relevant survival period set forth in Section 10.1.

(c) Notwithstanding anything to the contrary in this Agreement, if any Buyer Indemnitee asserts a Claim against or seeks to collect any Loss from an Indemnifying Party in respect of a Claim or Loss arising out of any breach of a representation or warranty for which WGP-KHC has a right to indemnification or reimbursement from any Third Person under any one or more of the Amoco Agreements (a “Covered Third Person Claim”), then, the Buyer

Indemnitee shall, promptly following the time at which it submits a Claim Notice to the Indemnifying Party pursuant to this Section 10.5, cause WGP-KHC to assert a Claim for indemnification or reimbursement against such Third Person pursuant to and in accordance with the applicable Contract(s) under which such right(s) arise(s); provided, however, that the failure to initiate such Claim promptly shall not relieve the Indemnifying Party of any liability that it may have to any Indemnified Party with respect to such Claim or Loss except to the extent the Indemnifying Party shall have been prejudiced by such failure. If the Third Person rejects or denies liability for a Covered Third Person Claim, or otherwise fails to satisfy in full the Covered Third Person Claim on or before the date that is 60 days after the initial Claim Notice is delivered to Sellers (the “Applicable Time Period”), then the Buyer Indemnitee may thereafter pursue the Claim against the Indemnifying Party pursuant to this Article 10 by submitting a second Claim Notice to the Indemnifying Party within 60 days after any such rejection, denial or failure, notifying the Indemnifying Party thereof, in which case time periods specified in this Section 10.5 in connection therewith shall be deemed to have been tolled during the Applicable Time Period and through the delivery of the second Claim Notice.

(d) The Indemnifying Party shall have 30 days from receipt of the initial Claim Notice (the “Notice Period”) to notify the Indemnified Party in writing (i) whether or not the Indemnifying Party disputes the liability to the Indemnified Party hereunder with respect to the Claim or Loss, (ii) in any case in which Losses are asserted against or sought to be collected from an Indemnifying Party by an Indemnified Party, whether or not the Indemnifying Party desires at its own sole cost and expense to attempt to remedy such Losses or (iii) in any case in which Claims are asserted against or sought to be collected from an Indemnified Party by a Third Person (“Third Person Claim”), whether or not the Indemnifying Party desires at its own sole cost and expense to defend the Indemnified Party against such Third Person Claim.

(e) If the Indemnifying Party satisfies in full any Covered Third Person Claim, then (1) from and after the date thereof, the Indemnifying Party shall be subrogated to WGP-KHC’s rights to indemnification or reimbursement under the applicable Amoco Agreement with respect to such Covered Third Person Claim, (2) Buyer shall cause WGP-KHC to assign its rights to indemnification or reimbursement, as the case may be, under the applicable Amoco Agreement to the Indemnifying Party, and (3) Buyer shall cause WGP-KHC to cooperate with the Indemnifying Party in seeking to enforce any such rights and to collect any Losses relating to the Covered Third Person Claim, provided that the Indemnifying Party reimburses WGP-KHC for all costs and expenses incurred in connection therewith promptly following the receipt of a request for reimbursement therefor.

(f) Except as otherwise provided in Section 6.8(a), if the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third Person Claim, the Indemnifying Party shall have the right to defend all appropriate Proceedings with counsel of its own choosing (but reasonably satisfactory to the Indemnified Party) and such Proceedings shall be diligently prosecuted by it to settlement or a final conclusion. If the Indemnified Party desires to participate in any such defense or settlement, other than at the request of the Indemnifying Party, it may do so at its sole cost and expense. If the Indemnified Party joins in defending in any such Third Person Claim, the Indemnifying Party shall have full authority to determine all action to be taken with respect thereto. If the Indemnifying Party elects not to defend the Indemnified Party against a Third

Person Claim or does not provide an answer within the Notice Period, the Indemnified Party shall be entitled to assume the defense of all appropriate Proceedings related thereto with counsel of its choosing and the Indemnifying Party shall be responsible for paying for counsel for the Indemnified Party if they are otherwise entitled to indemnification with respect to such matter. If a Proceeding is asserted against both the Indemnifying Party and the Indemnified Party and there are one or more defenses available to the Indemnified Party that are not available to the Indemnifying Party or there is a conflict of interest that renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be responsible for paying for separate counsel for the Indemnified Party; provided, however, that, if there is more than one Indemnified Party, the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys (in addition to local counsel) to represent the Indemnified Parties, regardless of the number of Indemnified Parties. No compromise or settlement of any Proceeding may be effected by the Indemnifying Party without the Indemnified Party’s written consent unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement includes the granting by each claimant or plaintiff to each Indemnified Party of an unconditional release from all liability in respect of such Third Person Claim and the related Proceeding.

(g) If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel, at the cost and expense of the Indemnifying Party, in contesting any Third Person Claim, in making any counterclaim against the Third Person asserting the Third Person Claim or in making any cross-complaint against any Person. Notwithstanding anything to the contrary contained in this Agreement, no Third Person Claim may be settled or otherwise compromised without the prior written consent of the Indemnifying Party.

(h) The costs and expenses of a Buyer Indemnitee or Seller Indemnitee, including the fees, costs and expenses of its separate counsel, experts (including expert witnesses), consultants and any other representatives engaged by it, incurred in connection with the defense and settlement or final resolution of any Third Person Claim as to which such Buyer Indemnitee or Seller Indemnitee, as the case may be, has the right to control shall be treated as “Losses” for all purposes hereunder.

10.6 Exclusive Remedy. AS BETWEEN THE BUYER INDEMNITEES AND SELLERS, ON ONE HAND, AND THE SELLER INDEMNITEES AND THE PARTNERSHIP OR BUYER, ON THE OTHER, AFTER CLOSING, OTHER THAN WITH RESPECT TO CLAIMS FOR FRAUD, (A) THE PROVISIONS SET FORTH IN THIS ARTICLE 10 SHALL BE THE SOLE AND EXCLUSIVE RIGHTS, OBLIGATIONS AND REMEDIES OF THE PARTIES WITH RESPECT TO THIS AGREEMENT, THE EVENTS GIVING RISE THERETO, AND THE TRANSACTIONS PROVIDED FOR HEREIN OR CONTEMPLATED HEREBY AND EXCEPT AS OTHERWISE PROVIDED IN THIS ARTICLE 10 THE BUYER INDEMNITEES RELEASE THE SELLER INDEMNITEES FROM ANY LIABILITIES OF ANY KIND WHATSOEVER ARISING AT ANY TIME IN CONNECTION IN ANY WAY WHATSOEVER WITH THE FRONTSTREET COMPANIES AND ARISING UNDER ANY ENVIRONMENTAL LAWS OR WITH REGARD TO ANY HAZARDOUS MATERIALS OR ENVIRONMENTAL CONDITIONS AND (B) NO PARTY OR ANY OF ITS SUCCESSORS

OR ASSIGNS SHALL HAVE ANY RIGHTS AGAINST ANY OTHER PARTY OR ITS AFFILIATES OTHER THAN AS IS EXPRESSLY PROVIDED IN THIS ARTICLE 10.

10.7 Limitation on Damages. SUBJECT TO SECTION 10.6 NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL ANY PARTY BE LIABLE AFTER THE CLOSING TO ANY OTHER PARTY, OR TO ANY INDEMNITEE, UNDER THIS AGREEMENT FOR ANY EXEMPLARY, PUNITIVE, REMOTE, SPECULATIVE, OR SPECIAL DAMAGES, AND NO CLAIM SHALL BE MADE OR AWARDED AGAINST ANY PARTY, FOR ANY SUCH DAMAGES; PROVIDED, HOWEVER, SUBJECT TO THE LIMITATIONS IN SECTION 10.4, THIS SECTION 10.7 SHALL NOT LIMIT THE RIGHT OF THE BUYER TO RECOVER ANY LOSS TO THE EXTENT (a) ACTUALLY SUFFERED, INCURRED OR PAID BY THE BUYERS TO ANY THIRD PARTY OR WITH RESPECT TO ANY THIRD PARTY OBLIGATION OR (b) ARISING OR RESULTING FROM A BREACH OF SECTION 4.12 OR SECTION 4.16.

10.8 Bold and/or Capitalized Letters. THE PARTIES ACKNOWLEDGE THAT THE BOLD AND CAPITALIZED LETTERS IN THIS AGREEMENT CONSTITUTE CONSPICUOUS LEGENDS.

No Party may assign this Agreement or any of its rights or obligations arising hereunder without the prior written consent of the other Parties; provided, however, that without the consent of Sellers, Buyer may, without relieving Buyer from its liabilities or obligations hereunder, (a) assign this Agreement, and its rights and obligations hereunder, to an Affiliate of Buyer or to an entity formed, controlled and primarily owned by Buyer, (b) collaterally assign this Agreement to any entity providing financing to Buyer or (c) both.

11.3 Entire Agreement, Amendments and Waiver.

11.4 Severability. Each portion of this Agreement is intended to be severable. If any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement.

Each Party agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

Notice by messenger, overnight delivery service, facsimile transmission or personal delivery shall be deemed given on the date of actual delivery.

11.8 Press Releases. Except as may otherwise be required by securities Laws and public announcements or disclosures that are, in the reasonable opinion of the Party proposing to make the announcement or disclosure, legally required to be made, there shall be prior to Closing no press release or public communication concerning the transactions contemplated by this Agreement by any Party except with the prior written consent of the Party not originating such press release or communication, which consent shall not be unreasonably withheld or delayed. Prior to Closing, the Partnership and Sellers will consult in advance on the necessity for, and the timing and content of, any communications to be made to the public and, subject to legal constraints, to the form and content of any application or report to be made to any Governmental Authority that relates to the transactions contemplated by this Agreement.

11.9 Offset. Nothing contained herein shall impair or constitute a waiver of any right of offset or setoff for any Party.

11.10 No Partnership; Third Party Beneficiaries. Nothing in this Agreement shall be deemed to create a joint venture, partnership, tax partnership, or agency relationship between the Parties. Nothing in this Agreement shall provide any benefit to any Third Person or entitle any Third Person to any claim, cause of action, remedy or right of any kind, it being the intent of the Parties that this Agreement shall not be construed as a third party beneficiary contract; provided, however, that the indemnification provisions of Article 10 shall inure to the benefit of the Buyer Indemnitees and the Seller Indemnitees as provided therein.

11.11 Negotiated Transaction. The Parties, each represented by legal counsel, have each participated in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation should arise, this Agreement shall be construed as if drafted by all Parties and no presumption or burden of proof shall arise favoring or burdening any Party hereto by virtue of the authorship of any of the provisions of this Agreement.

11.12 Disclosure Schedules. The information in the Disclosure Schedules constitutes (a) exceptions or qualifications to particular representations, warranties, covenants and obligations of Sellers as set forth in this Agreement or (b) descriptions or lists of assets and liabilities and other items referred to in this Agreement. The Disclosure Schedules shall not be construed as indicating that any disclosed information is required to be disclosed, and no disclosure shall be construed as an admission that such information is material to, or required to be disclosed by, Sellers. Capitalized terms used in the Disclosure Schedules that are not defined therein are defined in this Agreement shall have the meanings given to them in this Agreement. The statements in the Disclosure Schedules relate only to the provisions in the Section of this Agreement to which they expressly relate and not to any other provisions in this Agreement, unless its applicability to another Section of this Agreement is readily apparent.

11.13 Time of the Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

11.14 Specific Performance. The Parties recognize that, if any Party should refuse to perform under the provisions of this Agreement, monetary damages alone may not be adequate. The Parties shall therefore be entitled, in addition to any other remedies that may be available, including money damages, to seek specific performance of the terms of this Agreement. In the event of any action to enforce this Agreement specifically, the Parties hereby waive the defense that there is an adequate remedy at law.

11.15 Affiliate Liability.

(a) Each of the following is herein referred to as a “Buyer Affiliate”: (i) any direct or indirect holder of the Common Units, Subordinated Units, General Partner Units or other Equity Interests in the Partnership or Buyer (whether limited or general partners, members, stockholders or otherwise), and (ii) any director, officer, manager, employee, representative or agent of (A) the Partnership, the Managing General Partner or Buyer or any Subsidiary of any of them or (B) any Person who directly or indirectly controls the Partnership or Buyer. Except to the extent that a Buyer Affiliate is an express signatory thereto or an express assignee of the Partnership or Buyer, no Buyer Affiliate shall have any liability or obligation to Sellers of any nature whatsoever in connection with or under this Agreement, any of the Transaction Documents or the transactions contemplated herein or therein, and each Seller on behalf of itself and each FrontStreet Company and Affiliate of such Seller hereby waives and releases all claims of any such liability and obligation. Notwithstanding the foregoing, neither Sellers nor Aircraft Services Corporation shall be deemed an Affiliate of the Partnership.

(b) Each of the following is herein referred to as a “Seller Affiliate”: (A) any direct or indirect holder of Equity Interests in the Sellers (whether limited or general partners, members, stockholders or otherwise), other than Aircraft Services Corporation, and (B) any partner, member, shareholder, director, officer, manager, employee, representative or agent of (1) Sellers or either FrontStreet Company or any Subsidiary of either of them or (2) any Person, other than Aircraft Services Corporation, who directly or indirectly controls either Seller. Except to the extent that a Seller Affiliate is an express signatory thereto or an express assignee of a Seller, no Seller Affiliate shall have any liability or obligation to the Partnership, Buyer or any Buyer Indemnitee of any nature whatsoever in connection with or under this Agreement, any of the Transaction Documents or the transactions contemplated herein or therein, and the Partnership and Buyer on behalf of themselves and the Buyer Affiliates hereby waive and release all claims of any such liability and obligation.

11.16 No Waiver of Claims for Fraud. The liability of any Party under Article 10 shall be in addition to, and not exclusive of, any other liability that such Party may have at law or equity based on such Party’s fraudulent acts or omissions. None of the provisions set forth in this Agreement shall be deemed a waiver by any Party of any right or remedy that such Party may have at law or equity based on any other Party’s fraudulent acts or omissions, nor shall any such provisions limit, or be deemed to limit, (a) the amounts of recovery sought or awarded in any such claim for fraud, (b) the time period during which a claim for fraud may be brought, or (c) the recourse which any such Party may seek against another Party with respect to a claim for

fraud; provided, however, that with respect to such rights and remedies at law or equity, the Parties further acknowledge and agree that none of the provisions of this Section 11.16 shall be deemed a waiver of any defenses that may be available in respect of actions or claims for fraud, including defenses of statutes of limitations or limitations of damages.

11.17 No Recovery. Sellers shall not be entitled to, and effective as of the Closing do hereby waive any rights to, indemnification or contribution from each FrontStreet Company for any Losses that it is obligated to pay pursuant to any Claim brought by a Buyer Indemnitee. If any right of indemnification or contribution from either FrontStreet Company under the Organizational Documents of such FrontStreet Company relating to a Claim is ultimately determined to be unwaivable, Sellers shall indemnify the Buyer or the applicable FrontStreet Company to the full extent of such recovery. Sellers hereby waive and release any and all rights that it may have to assert claims of indemnification or contribution against either FrontStreet Company under this Agreement, any other Transaction Document, any other Contract or any provision of its Organizational Documents for any Losses that Sellers are obligated to pay pursuant to any Claim brought by a Buyer Indemnitee.

Exhibit A-1

EXHIBIT A

MUTUAL RELEASE
(INDIVIDUAL)

This Mutual Release (the “Release”) is entered into as of the 10th day of December, 2007, by and among [ ] in all capacities, including without limitation in his, her or its capacity as a direct or indirect owner of an Equity Interest in any FrontStreet Company (as hereinafter defined) and/or as a director, officer, partner, member, manager, shareholder and/or employee of ASC Hugoton LLC, a Delaware limited liability company (“ASC”), FrontStreet Hugoton, LLC, a Delaware limited liability company (“FrontStreet”), WGP-KHC LLC, a Delaware limited liability company and wholly owned subsidiary of FrontStreet (“WGP-KHC” and, together with FrontStreet, each a “FrontStreet Company” and collectively the “FrontStreet Companies”), FrontStreet EnergyOne LLC, a Delaware limited liability company (“EnergyOne”), and/or FrontStreet Partners LLC, a Delaware limited liability company (“FrontStreet Manager”) (the “Releasing Party”), on the one hand, and the FrontStreet Companies, Regency GP LLC, a Delaware limited liability company (“GP Parent”), Regency GP LP, a Delaware limited partnership (“Regency GP”), Regency Energy Partners LP, a Delaware limited partnership (“Regency”), and Regency Gas Services LP, a Delaware limited partnership and wholly owned subsidiary of Regency (“Gas Services” and, together with Regency, the “Buyers”), on the other.

RECITALS

WHEREAS, Buyers, ASC and EnergyOne are parties to that certain Contribution Agreement, dated as of December 10, 2007 (the “Contribution Agreement”); and

WHEREAS, to induce Buyers to enter into and perform their respective obligations under the Contribution Agreement, the Releasing Party has agreed to execute, deliver and perform its obligations under this Release and it is a condition to the execution of the Contribution Agreement by Buyers that Buyers, GP Parent, Regency GP, the Releasing Party and the FrontStreet Companies enter into this Release at or prior to execution of the Contribution Agreement.

NOW, THEREFORE, in consideration of the above premises, the mutual covenants herein contained and for other good and valuable consideration (the receipt, adequacy and sufficiency of which are hereby acknowledged), the parties agree as follows:

1. Release of the Company Group. Effective as of the Closing under the Contribution Agreement and without any further action by any party hereto:

(a) Subject to Section 1(d), the Releasing Party, for himself, herself or itself and for his, her or its estate, executors, heirs, representatives and assigns, hereby finally, unconditionally, irrevocably and absolutely forever releases, acquits, remises and discharges:

Exhibit A-2

and employees, and all of the foregoing persons’ predecessors, successors, assigns, agents and representatives (collectively, the “Company Group”), from any and all Claims that the Releasing Party may now have, have ever had, or that might subsequently accrue to the Releasing Party, including without limitation any Claims (i) that may be asserted derivatively, whether on behalf of any FrontStreet Company or otherwise, against any current or former officer, director, partner, member, manager, shareholder or employee of any member of the Company Group, including without limitation with respect to the negotiation, execution and delivery of the Contribution Agreement or any other Transaction Document or otherwise related to the transactions contemplated thereby, (ii) relating to breach of fiduciary duty, (iii) relating to breach of or arising pursuant to rights under the Organizational Documents of any FrontStreet Company, (iv) relating to requests for information or any failure to provide required reports or complete or correct information to the Releasing Party, or any officers and/or directors of any FrontStreet Company, (v) relating to the operation or management of any FrontStreet Company by the officers, directors, members, managers and Affiliates of such FrontStreet Company, or (vi) relating to any failure of any FrontStreet Company to offer the Releasing Party the right to acquire any additional Equity Interests of any member of the Company Group or any violation of any preemptive rights of the Releasing Party; and

(2) each agent, consultant, advisor, fiduciary and other representative (including legal counsel, accountants and financial advisors) of each FrontStreet Company (the “Extended Company Parties”) from and against any and all Claims that the Releasing Party may now have, have ever had, or that might subsequently accrue to the Releasing Party that may be asserted derivatively, whether on behalf of any FrontStreet Company or otherwise, against any Extended Company Party to the extent arising as a result of or in connection with or related to the negotiation, execution and delivery of the Contribution Agreement or any other Transaction Document or otherwise related to the transactions contemplated thereby ((1) and (2), collectively, the “Releasing Party Released Claims”).

(b) THE RELEASE IN SECTION 1(a) IS SPECIFICALLY INTENDED TO OPERATE AND BE APPLICABLE EVEN IF IT IS ALLEGED, CHARGED OR PROVEN THAT ALL OR SOME OF THE CLAIMS OR DAMAGES RELEASED WERE SOLELY AND COMPLETELY CAUSED BY ANY ACTS OR OMISSIONS, WHETHER NEGLIGENT, GROSSLY NEGLIGENT, INTENTIONAL OR OTHERWISE, OF OR BY THE COMPANY GROUP OR ANY EXTENDED COMPANY PARTY.

(c) The Releasing Party represents and warrants that the Releasing Party has not transferred, pledged, assigned or otherwise hypothecated to any other Person all or any portion of any Releasing Party Released Claims (or any Claims that would constitute Releasing Party Released Claims but for any such transfer, pledge or assignment) or any rights or entitlements with respect thereto and the execution and delivery of this Release does not violate or conflict with the terms of any contract, agreement or other instrument to which the Releasing Party is a party or by which the Releasing Party otherwise is bound.

(d) (i) Nothing contained in this Release is intended to, nor does it, limit, impair or otherwise modify or affect any rights of the Releasing Party or the obligations of Buyers or any FrontStreet Company expressly set forth in or contemplated under the Contribution Agreement or any other Transaction Document and any facts, circumstances or Claims to the extent entitling

Exhibit A-3

the Releasing Party to any recovery under the Contribution Agreement or any other Transaction Document.

(ii) Nothing contained in this Release is intended to, nor does it, limit, impair or otherwise modify or affect any rights of the Releasing Party or the obligations of any member of the Company Group, other than Buyers, GP Parent, Regency GP, each of their respective Affiliates controlled by Regency and the FrontStreet Companies, with respect to any Claim the Releasing Party may have against such Person to the extent (A) such Claim is independent of such Person’s actions in his, her or its capacity as an officer, director, partner, member, manager, shareholder or employee of any FrontStreet Company or any of its respective Affiliates and (B) neither Buyers, GP Parent, Regency GP nor any of their respective Affiliates controlled by Regency or any FrontStreet Company has any direct or indirect liability with respect to such Claim.

(iii) Furthermore, none of the provisions set forth in this Release shall be deemed a waiver by the Releasing Party of any right or remedy that the Releasing Party may have, at law or in equity, based on fraudulent acts or omissions of any member of the Company Group or any Extended Company Party in connection with the transactions contemplated by the Contribution Agreement, nor shall any such provisions limit, or be deemed to limit, (A) the amounts of recovery sought or awarded in any such claim for fraud, (B) the time period during which a claim for fraud may be brought, or (C) the recourse that the Releasing Party may seek against any member of the Company Group or any Extended Company Party with respect to a claim for fraud.

(e) The Releasing Party acknowledges and agrees that the provisions of Section 1(a) are valid, fair, adequate and reasonable and were agreed to with his, her or its full knowledge and consent, were not procured through fraud, duress or mistake and have not had the effect of misleading, misinforming or failing to inform the Releasing Party.

(f) The Releasing Party hereby irrevocably covenants to refrain from, directly or indirectly, asserting any Claim or demand, or commencing, instituting or causing to be commenced, or assisting any party in the commencement of any action, proceeding, arbitration, audit, hearing, investigation, litigation, or suit (whether civil, criminal, administrative, investigative or informal) of any kind against any member of the Company Group or any Extended Company Party based upon any Releasing Party Released Claims released or purported to be released hereby. The Releasing Party understands and agrees that he, she or it is expressly waiving all Claims against the Company Group and the Extended Company Parties covered by this Release, including, but not limited to, those Claims that it may not know of or suspect to exist, which if known, may have materially affected the decision to provide this Release, and the Releasing Party expressly waives any rights under applicable law that provide to the contrary.

2. Release of the Releasing Party Group. Effective as of the Closing under the Contribution Agreement and without any further action by any party hereto:

(a) Subject to Section 2(d), each Buyer, GP Parent, Regency GP and each FrontStreet Company, for itself and for its past, present and future officers, directors, shareholders, members,

Exhibit A-4

managers, partners, employees and all of the foregoing persons’ predecessors, successors, assigns, agents and representatives (collectively the “FrontStreet Releasors”), hereby finally, unconditionally, irrevocably and absolutely forever releases, acquits, remises and discharges:

(1) The Releasing Party and the Releasing Party’s executors, heirs, estate, legal representatives, assigns and agents (collectively, the “Releasing Party Group”) from any and all Claims that any FrontStreet Releasor may now have, has ever had, or that might subsequently accrue to any of them, including without limitation any Claims (i) with respect to the negotiation, execution and delivery of the Contribution Agreement or any other Transaction Document or otherwise related to the transactions contemplated thereby, (ii) relating to a breach of fiduciary duty or (iii) relating to the operation or management of any FrontStreet Company; and

(2) each agent, consultant, advisor, fiduciary and other representative (including legal counsel, accountants and financial advisors) of the Releasing Party (the “Extended Released Parties”) from and against any and all Claims that any FrontStreet Company may now have, has ever had, or that might subsequently accrue to the FrontStreet Releasors that may be asserted derivatively, against any Extended Released Party to the extent arising as a result of or in connection with or related to the negotiation, execution and delivery of the Contribution Agreement or any other Transaction Document or otherwise related to the transactions contemplated thereby ((1) and (2), collectively, the “FrontStreet Released Claims”).

(b) THE RELEASE IN SECTION 2(a) IS SPECIFICALLY INTENDED TO OPERATE AND BE APPLICABLE EVEN IF IT IS ALLEGED, CHARGED OR PROVEN THAT ALL OR SOME OF THE CLAIMS OR DAMAGES RELEASED WERE SOLELY AND COMPLETELY CAUSED BY ANY ACTS OR OMISSIONS, WHETHER NEGLIGENT, GROSSLY NEGLIGENT, INTENTIONAL OR OTHERWISE, OF OR BY THE RELEASING PARTY OR ANY EXTENDED RELEASED PARTY.
