this Agreement to the Closing Date, Sellers shall, and shall use Commercially Reasonable Efforts to cause each Buckeye Affiliate to:

(b) Without limiting the generality of the foregoing, and, except as contemplated in this Agreement or as described in Schedule 5.1, or as required under applicable Law or by any Governmental Authority, prior to the Closing Date, without the prior written consent of Buyer (which consent shall not be unreasonably withheld), Sellers shall not, and shall use Commercially Reasonable Efforts to cause the Buckeye Affiliates (unless the board of directors of either MainLine or Buckeye GP is advised by counsel that the failure to do so would be a breach of their fiduciary duty to the limited partners of BGH or BPL, respectively) not to:

(i) modify, amend or voluntarily terminate, prior to the expiration date thereof, any Material Contracts or waive any default by, or release, settle or compromise any claim against, any other party thereto, other than as may be required in connection with Sellers’ obligations to Buyer under this Agreement;

(vi) (A) settle any claims, demands, lawsuits or state or federal regulatory proceedings for damages to the extent such settlements in the aggregate assess damages in excess of $5,000,000 (other than any claims, demands, lawsuits or proceedings to the extent insured (net of deductibles), reserved against in the Financial Statements or covered by an indemnity obligation not subject to dispute or adjustment from a solvent indemnitor) or (B) settle any claims, demands, lawsuits or state or federal regulatory proceedings seeking an injunction or other equitable relief where such settlements would have or would reasonably be expected to have a Material Adverse Effect on the Buckeye Affiliates;

(vii) make any material change to its financial reporting and accounting methods other than as required by a change in GAAP; or

(viii) agree to do any of the foregoing.

Section 5.2 Access to Information.

(a) Between the date of this Agreement and the Closing Date, Sellers will, to the fullest extent permitted by Law, cause the BGH Entities and the BPL Entities to, during ordinary business hours and upon reasonable notice, (i) give Buyer and its Representatives reasonable access to the books, records, contracts, offices and other facilities and properties of the BGH Entities and the BPL Entities (provided that Sellers or their designee(s) may, in the sole discretion of Sellers, accompany the person(s) to whom such access is provided as contemplated herein), (ii) furnish Buyer with such financial and operating data and other information with respect to the BGH Entities and BPL Entities as Buyer may from time to time reasonably request, (iii) make available to Buyer a copy of each material report, schedule or other document filed or received by them with respect to any of the BGH Entities or BPL Entities with the SEC, FERC or any other Governmental Authority having jurisdiction over any such entity; and (iv) access to Representatives of the BGH Entities and BPL Entities; provided, however, that (A) any such access or activities shall be conducted in such a manner as not to interfere unreasonably with the operation of any of the BGH Entities and BPL Entities, (B) none of Sellers or any of the BGH Entities or BPL Entities shall be unreasonably required to prepare special records, reports, analysis or other information that they do not prepare in the ordinary course of business, (C) none of Sellers or any of the BGH Entities or BPL Entities shall be required to take any action that would constitute a waiver of the attorney-client privilege, and (D) none of Sellers or any of the BGH Entities or BPL Entities shall be required to supply Buyer with any information that such entities shall be legally prohibited to supply.

(b) Buyer and Sellers acknowledge that all information furnished to or obtained by Buyer or its Representatives pursuant to this Section 5.2 shall be subject to the Confidentiality Agreement.

(c) Buyer agrees that, prior to the Closing Date, it will not contact any vendors, suppliers, employees, or other contracting parties of any BGH Entity or BPL Entity with respect

to any aspect of the business of the BGH Entities or BPL Entities or the transactions contemplated hereby, without the prior written consent of Sellers, which consent shall not be unreasonably withheld.

(d) Buyer agrees that it shall preserve and keep all books and records relating to the business or operations of the BGH Entities and BPL Entities on or before the Closing Date in Buyer’s possession for a period of at least six years after the Closing Date. Notwithstanding the foregoing, Buyer agrees that it shall preserve and keep all books and records of the BGH Entities and BPL Entities relating to any audit or investigation instituted by a Governmental Authority or any litigation (whether or not existing on the Closing Date) if it is reasonably likely that such investigation or litigation may relate to matters occurring prior to the Closing, without regard to the six-year period set forth in this Section 5.2(d).

Section 5.3 Expenses. Except to the extent specifically provided herein, whether or not the transactions contemplated hereby are consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby, including the cost of legal, technical and financial consultants shall be borne by the Party incurring such costs and expenses. Notwithstanding anything to the contrary herein, Buyer will pay the cost and expenses of (i) all filing fees under the HSR Act, (ii) filing for and prosecuting applications for Buyer’s Required Regulatory Approvals and (iii) all of the incremental administrative costs of additional K-1 preparation resulting from the tax termination of BGH (provided this clause (iii) shall not be construed as an agreement by any Seller or Buyer to hold harmless any holder of common units of BGH from any reduced tax benefits to them associated with the tax termination of BGH). Notwithstanding anything to the contrary herein, Sellers will pay for filing and prosecuting applications for Sellers’ Required Regulatory Approvals (excluding the HSR Act) (including filing and prosecuting applications for PAPUC) and any fees associated with the waivers under the BPL Credit Facility and BGH Credit Facility. In the event Buyer retains its own counsel with respect to the PAPUC, it shall be responsible for such fees and expenses.

Section 5.4 Further Assurances; Cooperation. Subject to the terms and conditions of this Agreement, each of the Parties hereto will use its respective Commercially Reasonable Efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the sale of the Subject Interests pursuant to this Agreement, including Commercially Reasonable Efforts to ensure satisfaction of the conditions precedent to each Party’s obligations hereunder. Neither of the Parties hereto will, without the prior written consent of the other Party, take or fail to take any action, that would reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement. From time to time after the Closing Date, without further consideration, each Party will, at its own expense, execute and deliver such documents to the other Party as the other Party may reasonably request in order to more effectively consummate the sale and purchase of the Subject Interests hereunder.

Section 5.5 Public Statements. Between the date hereof and the Closing Date, the Parties shall not issue any public announcement, statement or other disclosure with respect to this Agreement or the transactions contemplated hereby without the prior written consent of the other Party, which consent will not be unreasonably withheld or delayed, except as may be required by Law or the rules of the New York Stock Exchange.

Section 5.6 Consents and Approvals.

(a) As promptly as practicable but in any event not later than ten (10) Business Days after the date of this Agreement, Sellers and Buyer shall each file or cause the BGH Entities or the BPL Entities to file with the Federal Trade Commission and the Department of Justice any notifications and other documents required to be filed by such Party under the HSR Act and the rules and regulations promulgated thereunder with respect to the transactions contemplated hereby. The Parties shall consult with each other as to the appropriate time of filing such notifications or other documents and shall agree upon the timing of such filings, to respond promptly to any requests for additional information made by either of such agencies, and to cause the waiting periods under the HSR Act to terminate or expire at the earliest possible date after the date of filing. Buyer will pay all filing fees under the HSR Act but each Party will bear its own costs for the preparation of any such filing.

(b) As promptly as practicable but in any event not later than fifteen (15) days after the date of this Agreement, Sellers and Buyer, as applicable, shall file or cause the BGH Entities or the BPL Entities to file with PAPUC or any other Governmental Authority having jurisdiction over any BGH Entity or BPL Entity, any filings required to be made with respect to the transactions contemplated by this Agreement and to obtain, at the earliest practicable date, all Sellers’ Required Regulatory Approvals and Buyer’s Required Regulatory Approvals, respectively. The Parties shall respond promptly to any requests for additional information made by such agencies, and use their respective Commercially Reasonable Efforts to cause regulatory approval to be obtained at the earliest possible date after the date of filing. Each Party will bear its own costs of the preparation of any such filing.

(c) Sellers and Buyer shall in good faith cooperate with each other and (i) promptly prepare and file all necessary documentation, (ii) effect all necessary applications, notices, petitions and filings and execute all agreements and documents, (iii) use good faith Commercially Reasonable Efforts to obtain the transfer or issuance to Buyer of all necessary consents, approvals and authorizations of all Governmental Authorities at the earliest possible date and (iv) use good faith Commercially Reasonable Efforts to obtain all necessary consents, approvals and authorizations of all other parties at the earliest possible date, in the case of each of the foregoing clauses (i), (ii), and (iii), necessary or advisable to consummate the transactions contemplated by this Agreement (including Sellers’ Required Regulatory Approvals and Buyer’s Required Regulatory Approvals) or required by the terms of any note, bond, mortgage, indenture, deed of trust, license, franchise, permit, concession, contract, lease or other instrument to which any of Sellers, the BGH Entities, BPL Entities or Buyer is a party or by which any of them is bound. If any such consent cannot be obtained, Sellers shall cooperate in any reasonable arrangement designed to obtain for Buyer all benefits, privileges and obligations of the applicable instrument, contract, license, lease, permit, or document, including, without limitation, possession, use, risk of loss, potential for gain and dominion, control and demand. Each of Sellers and Buyer shall have the right to review in advance all filings to be made by the other with any Governmental Authority in connection with the transactions contemplated hereby.

(d) Notwithstanding anything in this Agreement, Buyer agrees that Sellers’ obligations under this Agreement shall in no way require the BGH Entities or the BPL Entities to

accept any condition or requirement of any regulatory approval that is or could reasonably be determined to be adverse to the limited partners of BGH or BPL, as the case may be.

Section 5.7 Fees and Commissions. Sellers and Buyer each represent and warrant to the other that no broker, finder or other Person is entitled to any brokerage fees, commissions or finder’s fees in connection with the transactions contemplated hereby, except that ▇▇▇▇▇▇ Brothers Inc. is entitled to a financial advisory fee pursuant to its engagement with Buyer in connection with the transactions contemplated by this Agreement. Sellers and Buyer will pay to the other or otherwise discharge, and will indemnify and hold the other harmless from and against, any and all claims or liabilities for all brokerage fees, commissions and finder’s fees incurred by reason of any action taken by the indemnifying party.

Section 5.8 Tax Matters.

(a) Tax Returns for Periods Ending On or Prior to the Closing Date. Sellers shall prepare or cause to be prepared and shall file or cause to be filed all Tax Returns of any of the BGH Entities that are required to be filed after the Closing Date with respect to taxable periods ending on or prior to the Closing Date, other than any such Tax Returns relating to Taxes for which the BGH Entities will be reimbursed by the BPL Entities. The Sellers shall cause to be included in such Tax Returns any income, gain, loss, deduction, or other Tax item (“Tax Items”) required to be included therein, and pay any Taxes owed with respect to such Tax Returns. For purposes of the Texas franchise tax, the term “taxable periods” as used in this Section 5.8(a) and in Section 5.8(b) shall mean the accounting periods used in calculating the franchise tax and not the privilege periods.

(b) Tax Returns for Periods Ending After the Closing Date. With respect to each Tax Return of any of the BGH Entities for a taxable period beginning on or before the Closing Date that is required to be filed after the Closing Date, other than Tax Returns described in (a), Buyer shall cause such Tax Return to be prepared consistent with past practice or as required by Law, and shall cause to be included in such Tax Return all Tax Items required to be included therein. Buyer shall determine by an interim closing of the books, except for real property, ad valorem and similar Taxes that shall be prorated on a daily basis, the amount of Taxes due with respect to the period through the Closing Date (“Pre-Closing Taxes”). Buyer shall permit Sellers to review and comment on each such Tax Return and shall make such changes as are reasonably requested by Sellers. Sellers shall be required to pay to the Buyer in immediately available funds the amount of any such Taxes not later than five (5) days prior to the relevant due date (including extensions) for filing any such Tax Return.

(c) Cooperation on Tax Matters.

(i) Buyer and Sellers shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information reasonably relevant to any such audit, litigation, or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The BGH Entities, Sellers, and

Buyer shall (A) retain all books and records with respect to Tax matters pertinent to the BGH Entities or BPL Entities relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and, to the extent notified by Buyer or Sellers, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Party so requests, the BGH Entities or the BPL Entities or Sellers, as the case may be, shall allow the other Party to take possession of such books and records.

(ii) Buyer and Sellers further agree, upon request, to use their Commercially Reasonable Efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

(d) Certain Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with this Agreement (“Transfer Taxes”) shall be paid equally by Buyer and Sellers when due, and Buyer and Sellers shall, at their own expense, file all necessary Tax Returns and other documentation with respect to such Transfer Taxes, and, if required by applicable law, the Parties agree to join in the execution of any such Tax Return and other documentation.

(e) Purchase Price Allocation. Buyer and Seller agree that the sale of the Subject Interests are subject to Section 1060 of the Code. The purchase price allocation for the Non-C/R Units shall be allocated among Sellers pro rata based upon the number of Non-C/R Units sold by each Seller. Carlyle/Riverstone and Buyer agree to (i) use commercially reasonable efforts to agree on the allocation of the C/R Purchase Price between the MainLine Interest and the C/R Units, (ii) treat and report the transactions contemplated by this Agreement in all respects consistent with such agreed allocation for purposes of any Taxes, and (iii) not take any action inconsistent with such obligations. If Carlyle/Riverstone and Buyer cannot agree on an allocation, they will report for tax purposes based on their own allocation. Buyer and Sellers shall duly prepare and timely file such reports and information returns as may be prescribed under Section 1060 of the Code, including Form 8594, and any similar returns or reports required under other applicable Law, to report the allocation of the Purchase Price as determined in accordance with this Section.

Section 5.9 Indemnification and Insurance.

(a) Buyer agrees that all rights to indemnification and exculpation existing in favor of any BGH Entity or BPL Entity or any present or former director, officer, employee, fiduciary or agent of any BGH Entity or BPL Entity, as provided in the respective Organizational Documents of the BGH Entities or BPL Entities in effect as of the date hereof, shall survive the Closing and shall continue in full force and effect for a period of not less than the applicable statute of limitations. Buyer shall not amend or restate any Organizational Document of the BGH Entities or BPL Entities, in any manner that would adversely effect the indemnification or exculpation rights of any such present or former director, officer, employee, fiduciary or agent.

(b) Buyer shall provide (or cause to be provided for, which includes the continuation of the current policy) each individual who served as a director or officer of any BGH Entity or BPL Entity at any time prior to the Closing Date (the “Covered Officers and Directors”) with liability insurance for a period of six (6) years after the Closing Date no less favorable in coverage and amount than any applicable insurance in effect immediately prior to the Closing Date. Such insurance shall, among other things, (i) not provide for any allocation of the coverage or benefits thereof to any Person other than the Covered Officers and Directors, (ii) provide coverage to the Covered Officers and Directors substantially identical to that which would be provided under a policy covering only “independent” directors of an entity and (iii) contain a “no-rescission” endorsement or the substantive equivalent thereof.

Section 5.10 No Solicitation.

(a) From and after the date hereof, unless this Agreement has been terminated pursuant to and in accordance with Article VIII hereof, none of Sellers or any of their respective officers, directors, employees, stockholders, representatives, agents, or anyone acting on behalf of them, shall, directly or indirectly, (i) encourage, solicit, engage in discussions or negotiations with, or provide any information to, any Person (other than Buyer or its Representatives) concerning any of the Subject Interests or the BPL Entities or BGH Entities, (ii) accept any offer or respond to any indications of interest from any Person concerning any of the Subject Interests, (iii) enter into an agreement, arrangement or understanding with any Person other than the Buyer or its Affiliates concerning any of the Subject Interests or (iv) make or authorize any statement, recommendation or solicitation in support of or concerning or otherwise facilitate any purchase or sale of securities or similar transaction involving any of the Subject Interests; provided, however, that this Section 5.10 shall in no way prohibit any member of the board of directors of (x) MainLine, in its capacity as the general partner of BGH or (y) Buckeye GP, in its capacity as the general partner of BPL, from taking any action required by his or her fiduciary duty.

(b) During the period commencing on the date of this Agreement and continuing until the Termination Date, at every meeting of limited partners of BGH called with respect to any of the following, and at every adjournment or postponement thereof, and on every action or approval by written consent of limited partners of BGH with respect to any of the following, each Seller shall vote, to the extent not voted by the Person(s) appointed as proxies under Section 5.10(c), or shall cause the record holder of any Subject Interests on the applicable record date to appear (in Person or by proxy) and vote the Subject Interests entitled to vote thereon:

(i) against approval of any proposal made in opposition to, or in competition with, consummation of the transactions contemplated by this Agreement; and

(ii) except as otherwise agreed to in writing in advance by Buyer, against any merger of or sale of assets by any of the BGH Entities or BPL Entities or any action, proposal, transaction or agreement that would compete with or serve to interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the transactions contemplated by this Agreement.

(c) Each Seller hereby irrevocably and unconditionally revokes any and all previous proxies granted with respect to the Subject Interests. By entering into this Agreement, each Seller

hereby irrevocably and unconditionally grants a proxy appointing ▇▇▇▇ ▇▇▇▇▇▇ of Buyer as such Seller’s attorneys-in-fact and proxies, with full power of substitution, for and in such Seller’s name, to vote, express, consent or dissent, or otherwise to utilize such voting power solely as specifically set forth in Section 5.10(b) as to the matters specified in Section 5.10(b). The proxy granted by each Seller pursuant to this Section 5.10(c) is coupled with an interest and is irrevocable and is granted to secure the voting agreement set forth above in consideration of Buyer entering into this Agreement and incurring certain related fees and expenses. Notwithstanding the foregoing, the proxy granted by each Seller shall be revoked upon termination of this Agreement in accordance with its terms. Subject to the immediately preceding sentence, such irrevocable proxy is executed and intended to be irrevocable.

(d) In the event that Buyer, pursuant to the voting agreement granted in Section 5.10(b) or the proxy granted in Section 5.10(c), elects to vote in favor of any matter specified in Section 5.10(b), then Buyer and Seller shall share equally in the Profits associated with such transaction regardless of the termination of this Agreement.

Section 5.11 Notice of Breach. Each Party shall promptly give to the other Parties written notice with particularity upon having knowledge of any matter that would constitute a breach by such Party of any representation, warranty, agreement or covenant of such Party contained in this Agreement. Sellers shall have the obligation prior to the Closing to supplement the Disclosure Schedules in a prompt manner with respect to any matter that would have been required to be set forth on or described in such Disclosure Schedule (a “Disclosure Schedule Update”). Any such supplemental disclosure (a) will not be deemed to have been disclosed as of the date of this Agreement for purposes of determining whether the conditions set forth in Article VI have been satisfied, and (b) shall be deemed to have cured any breach of representation, warranty, covenant or agreement relating to the matters set forth in such update for purposes of indemnification pursuant to Article VII.

Section 5.12 Confidential Information.

(a) For two (2) years after the Closing,

(i) Sellers and their respective Affiliates shall not, directly or indirectly, disclose to any Person any information not in the public domain or generally known in the industry, in any form, whether acquired prior to or after the Closing Date, relating to the business and operations of the BGH Entities or the BPL Entities, and

(ii) the Buyer and its Affiliates shall not, directly or indirectly, disclose to any Person any information not in the public domain or generally known in the industry, in any form, whether acquired prior to or after the Closing Date, relating to (a) Sellers, or (b) the business, operations or ownership of BGH Entities or the BPL Entities prior to the Closing Date; provided, however, that any such confidential information received, obtained or created in the course of defending any claim or action under Article VII hereof shall be disclosed for a period of two (2) years following the resolution of such claim or action.

(b) Notwithstanding the foregoing, Buyer, Sellers or their respective Affiliates may disclose any information relating to the business and operations of the BGH Entities or the BPL Entities, or Sellers, as the case may be,

(i) if required by law, regulatory authority or applicable stock exchange rule,

(ii) to such other Persons if, at the time such information is provided, such Person is already in the possession of such information, or

(iii) if required in connection with a claim for Indemnifiable Losses under Article VII.

Section 5.13 Employee Matters.

(a) For a period of 12 months following the Closing Date (except such changes required by applicable Law), Buyer will not materially and adversely change the severance plans or arrangements listed on Schedule 5.13(a) – Part 1 hereto with respect to any employee who was entitled to participate in such plan or arrangement as of the Closing Date. If the employment of any Person listed on Schedule 5.13(a) – Part 2 with all Buckeye Affiliates is terminated within 12 months after the Closing Date, Buyer shall pay and otherwise provide, or cause to be paid or otherwise provided (other than by a Buckeye Affiliate unless fully reimbursed by Buyer), to such Person severance payments and benefits due to such Person from any Buckeye Affiliate in accordance with the terms of the severance plans or arrangements listed on Schedule 5.13(a) – Part 1 hereto, as in effect and to which such Person was entitled as of the Closing Date.

(b) In addition, Buyer shall pay and otherwise provide, or cause to be paid or otherwise provided (other than by a Buckeye Affiliate unless fully reimbursed by Buyer), any amounts and other benefits that are or become due to any Person listed on Schedule 5.13(b) for all severance obligations of the Buckeye Affiliates under any employment agreement, severance, change in control or retention bonus plan or agreement or similar arrangement set forth on Schedule 5.13(b) hereto with any Buckeye Affiliate on the Closing Date to the extent such severance obligations (i) are caused by the transactions contemplated by this Agreement, together with any other event specified under such agreement, plan or arrangement and become payable within 12 months after the Closing Date (18 months in the case of obligations under the first Agreement listed on Schedule 5.13(b)) or (ii) otherwise become payable within 12 months after the Closing Date.

(c) The provisions of this Section 5.13 are solely for the benefit of the Parties and may not be enforced by any other Person. Nothing in this Agreement shall be deemed the establishment of, or an amendment to, any Plan or employment arrangement of Buyer or any Buckeye Affiliate.

(d) For the avoidance of doubt, the unit options and accumulated distribution equivalent rights (collectively, the “Awards”) outstanding under the Unit Option and Distribution Equivalent Plan shall remain outstanding following the Closing and shall be assumed, to the extent necessary, within the meaning of Section 8(a) of such Unit Option and Distribution Equivalent Plan, and thus vesting and payment of such Awards shall not be accelerated as a result of the transactions contemplated by this Agreement.

(a) Subject to Section 7.3, Buyer shall indemnify, defend and hold harmless Sellers and each of their Representatives (each, a “Seller Indemnitee”) from and against any and all claims, demands, suits, losses, liabilities, damages, obligations, payments, Taxes, costs and

expenses (including the costs and expenses of any and all actions, suits, proceedings, assessments, judgments, settlements and compromises relating thereto and reasonable attorneys’, consultants and experts’ fees and reasonable disbursements in connection therewith) (each, an “Indemnifiable Loss”), asserted against or that any Seller Indemnitee may suffer, sustain, or become subject to relating to, resulting from or arising out of any breach by Buyer of any representations, warranties, covenants or agreements contained in this Agreement; provided, that in determining whether any representation or warranty has been breached, such representation or warranty shall be construed as if Material Adverse Effect or materiality is not a qualification thereto.

(b) Subject to Section 7.3, Sellers shall, severally and not jointly, indemnify, defend and hold harmless Buyer and each of its Representatives (each, a “Buyer Indemnitee”) from and against any and all Indemnifiable Losses asserted against or that any Buyer Indemnitee may suffer, sustain, or become subject to relating to, resulting from or arising out of any breach by Sellers of any representations, warranties, covenants or agreements contained in this Agreement; provided, that in determining whether any representation or warranty has been breached, such representation or warranty shall be construed as if Material Adverse Effect or materiality is not a qualification thereto.

(c) The expiration or termination of any representation or warranty shall not affect the Parties’ obligations under this Section 7.2 if the Person required to provide indemnification under this Agreement (the “Indemnifying Party”) has received notice of the claim or event for which indemnification is sought prior to such expiration, termination or extinguishment.

(d) Without prejudice to the Parties’ rights to equitable remedies under Section 9.6 and the rights described in Section 5.9, the rights and remedies of Sellers and Buyer under this Article VII are exclusive and in lieu of any and all other rights and remedies that Sellers and Buyer may have under this Agreement or otherwise for monetary relief, with respect to (i) any breach of or failure to perform any covenant, agreement, or representation or warranty set forth in this Agreement, after the occurrence of the Closing, or (ii) the assets, liabilities, business, or operations of the BGH Entities and BPL Entities, as the case may be. The indemnification obligations of the Parties set forth in this Article VII apply only to matters arising out of this Agreement.

(e) Notwithstanding anything to the contrary herein, no Party (including an Indemnitee) shall be entitled to recover from any other Party (including an Indemnifying Party) for any liabilities, damages, obligations, payments, losses, costs, or expenses under this Agreement any amount in excess of the actual compensatory damages, court costs and reasonable attorneys’ and other advisor fees suffered by such Party. Except with respect to Third Party Claims made against any of Sellers or any of their Representatives, no Party shall have any indemnification obligation under this Article VII to any other Person with respect to any claims, demands, suits, losses, liabilities, damages, obligations, payments, costs or expenses consisting of incidental, indirect, consequential or punitive damages, or damages for lost profits, payable by a Seller Indemnitee or Buyer Indemnitee.

(f) Defense of Claims. If any Indemnitee receives notice of the assertion of any claim or of the commencement of any claim, action, or proceeding made or brought by any

Person who is not a Party to this Agreement or any Representative of a Party to this Agreement (a “Third Party Claim”) with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in any event such notice shall not be given later than thirty (30) calendar days after the Indemnitee’s receipt of notice of such Third Party Claim. Such notice shall describe the nature of the Third Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the Indemnifiable Loss that has been or may be sustained by the Indemnitee. The Indemnifying Party will have the right to participate in or, by giving written notice to the Indemnitee, to elect to assume the defense of any Third Party Claim at such Indemnifying Party’s expense and by such Indemnifying Party’s own counsel; provided, that the counsel for the Indemnifying Party who shall conduct the defense of such Third Party Claim shall be reasonably satisfactory to the Indemnitee. The Indemnitee shall cooperate in good faith in such defense at such Indemnitee’s own expense. If an Indemnifying Party elects not to assume the defense of any Third Party Claim, the Indemnitee may compromise or settle such Third Party Claim over the objection of the Indemnifying Party, which settlement or compromise shall conclusively establish the Indemnifying Party’s liability pursuant to this Agreement.

(g) (i) If, within twenty (20) calendar days after an Indemnitee provides written notice to the Indemnifying Party of any Third Party Claims, the Indemnitee receives written notice from the Indemnifying Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in Section 7.2(f), the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof (unless the Indemnifying Party is also a party to such proceeding and the Indemnitee determines in good faith that joint representation would be inappropriate based on a conflict of interest between the Indemnifying Party and the Indemnitee, in which case the Indemnitee shall have the right to engage not more than one firm as its own counsel, the fees and expenses of which shall be paid by the Indemnifying Party); provided, however, that if the Indemnifying Party shall fail to take reasonable steps necessary to defend diligently such Third Party Claim within twenty (20) calendar days after receiving notice from the Indemnitee that the Indemnitee believes the Indemnifying Party has failed to take such steps, the Indemnitee may assume its own defense and the Indemnifying Party shall be liable for all reasonable expenses thereof.

(ii) Without the prior written consent of the Indemnitee, the Indemnifying Party shall not enter into any settlement of any Third Party Claim that would lead to liability or create any financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder. If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within thirty (30) calendar days after its receipt of such notice, the Indemnifying Party shall be relieved of its obligations to defend such Third Party Claim and the Indemnitee may contest or defend such Third Party Claim. In such event, the maximum liability of the Indemnifying Party as to such

Third Party Claim will be the amount of such settlement offer plus reasonable costs and expenses paid or incurred by Indemnitee up to the date of said notice.

(h) Any claim by an Indemnitee on account of an Indemnifiable Loss that does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable, but in any event such notice shall not be given later than thirty (30) calendar days after the Indemnitee becomes aware of such Direct Claim, and the Indemnifying Party shall have a period of twenty (20) calendar days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such twenty (20) calendar day period, the Indemnifying Party shall be deemed to have accepted such claim. If the Indemnifying Party rejects such claim, the Indemnitee will be free to seek enforcement of its right to indemnification under this Agreement.

(i) If the amount of any Indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement or payment by, from or against any other entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith (together with interest thereon from the date of payment thereof to the date or repayment at the “prime rate” as published in The Wall Street Journal) shall promptly be repaid by the Indemnitee to the Indemnifying Party.

(j) A failure to give timely notice as provided in this Section 7.2 shall not affect the rights or obligations of any Party hereunder except if, and only to the extent that, as a result of such failure, the Party that was entitled to receive such notice was actually prejudiced as a result of such failure.

(k) No party shall be entitled to indemnification to the extent that any Indemnifiable Loss is reduced by any (i) insurance proceeds (after reduction for retroactive premium adjustments), (ii) benefit after taking into account any Tax-related loss actually utilized to reduce Taxes imposed on or payable by BGH Entities, as the case may be, or (iii) other proceeds or payments from third parties received by the Indemnitee with respect to or related to such Indemnifiable Loss.

Section 7.3 Limitations.

(a) With respect to any claim for indemnification by a Buyer Indemnitee, each Seller shall be severally liable only for the portion of such claim equal to the total amount of such claim multiplied by a fraction, the numerator of which shall be that portion of the Purchase Price paid to such Seller in accordance with Section 2.4 and the denominator of which shall be the Purchase Price;

(b) Except with respect to Indemnifiable Losses resulting from or arising out of breaches of representations or warranties for Sections 3.2, 3.3(a)(i), 3.4, 3.5, 3.6, 3.7, 4.2, 4.3(a)(i), 4.4 and 4.8, the indemnification obligations of Buyer or Sellers in Section 7.2(a) or Section 7.2(b), respectively, shall be subject to the following limitations:

(i) No indemnification for any Indemnifiable Losses asserted against Sellers shall be required unless and until the cumulative aggregate amount of such Indemnifiable Losses exceeds $[] (the “Deductible”), at which point each of the Sellers shall be obligated to indemnify the Buyer Indemnitees such Seller’s pro rata portion (calculated in accordance with Section 7.3(a)) of the amount of such Indemnifiable Losses in excess of the Deductible, provided however, that (A) the recovery by all Buyer Indemnitees, in aggregate, under this Article VII shall be limited to an aggregate amount equal to $[] (the “Cap Amount”) and (B) each Seller’s aggregate liability to all Buyer Indemnitees, in aggregate, shall not exceed such Seller’s pro rata portion (based upon the relative number of units set forth opposite the name of each Seller under the column “Total Units” on Schedule I) of the Cap Amount; and

(ii) no indemnification for any Indemnifiable Losses asserted against Buyer shall be required unless and until the cumulative aggregate amount of such Indemnifiable Losses exceeds the Deductible, at which point Buyer shall be obligated to indemnify the Seller Indemnitees the amount of such Indemnifiable Losses in excess of the Deductible, provided however, that the Seller Indemnitees’ recovery under this Article VII shall be limited to an aggregate amount equal to the Cap Amount; and

(c) For purposes of clarity, Indemnifiable Losses shall be limited solely to the extent that the party seeking indemnification is actually damaged thereby.

Article VIII

TERMINATION

Section 8.1 Termination.

(a) This Agreement may be terminated at any time prior to the Closing Date by mutual written consent of Sellers and Buyer.

(b) This Agreement may be terminated by Sellers or Buyer, if (i) any Federal or state court of competent jurisdiction shall have issued an order, judgment or decree permanently restraining, enjoining or otherwise prohibiting the Closing, and such order, judgment or decree shall have become final and nonappealable; (ii) any statute, rule, order or regulation shall have been enacted or issued by any Governmental Authority that, directly or indirectly, prohibits the consummation of the Closing; or (iii) the Closing contemplated hereby shall have not occurred on or before June 30, 2007 (the “Termination Date”); provided, that if any of Buyer’s Required Regulatory Approvals or Sellers’ Required Regulatory Approvals have not been obtained, diligent efforts are being undertaken to obtain such approval, authorization or consent, and all other conditions provided for in Article VI have been satisfied, waived, or are then capable of being satisfied but for the delay in Closing, then at the election of either party the Termination Date shall be extended an additional 90 days; provided, further, that the right to terminate this Agreement under clause (iii) of this Section 8.1(b) shall not be available to any Party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before such date.

(c) This Agreement may be terminated by Buyer or Sellers if any of Buyer’s Required Regulatory Approvals, the receipt of which is a condition to the obligation of Buyer to consummate the Closing as set forth in Section 6.1(c), shall have been denied (and a petition for rehearing or refiling of an application initially denied without prejudice shall also have been denied).

(d) This Agreement may be terminated by Sellers or Buyer, if any of Sellers’ Required Regulatory Approvals, the receipt of which is a condition to the obligation of Sellers to consummate the Closing as set forth in Section 6.2(c), shall have been denied (and a petition for rehearing or refiling of an application initially denied without prejudice shall also have been denied).

(e) This Agreement may be terminated by Buyer upon the occurrence of any of the following actions by the BGH Entities or the BPL Entities, unless Buyer consents in writing (which consent shall not be unreasonably withheld) within twenty Business Days from the receipt of written notice from Sellers of the intent of the BGH Entities or BPL Entities to effect such event:

(i) the issuance of any equity securities or grant of any option, warrant or right to acquire any equity securities or issue any security convertible into or exchangeable for its equity securities other than the issuance of up to an aggregate of $50,000,000 of equity securities of BPL;

(ii) the incurrence, assumption or guarantee of any new indebtedness for borrowed money in excess of an aggregate amount equal to $100,000,000;

(iii) the issuance of any securities convertible or exchangeable for debt securities of any BGH Entity or BPL Entity;

(iv) the entering into of any leases of real property, other than renewals of existing leases in the ordinary course of business, the net present value (calculated at the weighted average interest rate on BPL’s indebtedness) of which exceeds $50,000,000;

(v) the acquisition of any material assets or properties in excess of $100,000,000 in the aggregate except for inventory or linefill in the ordinary course of business consistent with past practice;

(vi) the redemption, retirement, purchase or other acquisition, directly or indirectly, of the equity interests of BGH or BPL other than in the ordinary course of business or declaration, setting aside or payment of distributions other than (A) regular quarterly cash distributions by BGH and BPL (with such amounts determined using the same methodology as recent quarterly distributions) and (B) any distributions by MainLine;

(vii) the making of any capital expenditures in excess of $20,000,000 in addition to the amounts of capital expenditures that were included in the 2007 budget delivered to Buyer and except as required on an emergency basis for the safety of persons or the environment; and

(viii) the sale of any assets with proceeds to BPL or BGH in excess of $10,000,000 in the aggregate, except in the ordinary course of business and consistent with past practice.

During the pendency of any such event, Sellers agree to use Commercially Reasonable Efforts to keep Buyer reasonably informed as to the progress of such matter and the occurrence of any related effects on the business of the BGH Entities and BPL Entities. Any of the foregoing actions that are consented to by Buyer pursuant to this Section 8.1(e) shall not effect Section 6.1.

(f) This Agreement may be terminated by Buyer if there has been a violation or breach by Sellers of any covenant, agreement, representation or warranty contained in this Agreement or any representation or warranty of Sellers shall have become untrue, in either case such that the conditions set forth in Sections 6.1(d) or 6.1(e) would not be satisfied (assuming for purposes of this Section 8.1(e) that the references in Sections 6.1(d) and 6.1(e) to “Closing Date” mean the date of termination pursuant to this Section 8.1(e)) and such violation or breach is not curable or, if curable, shall not have been cured by the date thirty (30) days after receipt by Sellers of written notice specifying particularly such violation or breach, and such violation or breach has not been waived by Buyer.

(g) This Agreement may be terminated by Sellers if there has been a violation or breach by Buyer of any covenant, agreement, representation or warranty contained in this Agreement or any representation or warranty of Buyer shall have become untrue, in either case such that the conditions set forth in Sections 6.2(e) or 6.2(f) would not be satisfied (assuming for purposes of this Section 8.1(g) that the references in Sections 6.2(e) and 6.2(f) to “Closing Date” mean the date of termination pursuant to this Section 8.1(g)) and such violation or breach is not curable or, if curable, shall not have been cured by the date thirty (30) days after receipt by Buyer of written notice specifying particularly such violation or breach, and such violation or breach has not been waived by Sellers.

Section 8.2 Procedure and Effect of Termination. In the event of termination of this Agreement by either or both of the Parties pursuant to this Article VIII, written notice thereof shall forthwith be given by the terminating Party to the other Party, whereupon, if this Agreement is terminated pursuant to any of Sections 8.1(a) through 8.1(e), the liabilities of the Parties hereunder will terminate and thereafter neither Party shall have any recourse against the other by reason of this Agreement, except as otherwise expressly provided in this Agreement. Notwithstanding any other provision of this Agreement, termination of this Agreement pursuant to Section 8.1(f) or Section 8.1(g) shall in no way limit or restrict the rights and remedies of Buyer against Sellers that have violated or breached any of the covenants, agreements, representations or warranties of this Agreement prior to the date of termination.

Section 9.4 Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party hereto, including by operation of law, without the prior written consent of each other Party, such consent not to be unreasonably withheld, nor is this Agreement intended to confer upon any other Person except the Parties hereto any rights, interests, obligations or remedies hereunder.

Section 9.5 No Third Party Beneficiary. Except for the provisions of Sections 5.9, 7.2(a) and 7.2(b) (which are intended for the benefit of the Persons identified therein), the terms and provisions of this Agreement are intended solely for the benefit of the Parties and their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person, any employee of the BGH Entities or BPL Entities, any beneficiary or dependents thereof, or any collective bargaining representative thereof.

Section 9.6 Enforcement of this Agreement. The Parties acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any Party (other than the failure by any Party to pay any amount required to be paid hereunder) and any such breach would cause the non-breaching parties irreparable harm. Accordingly, the Parties agree that, in the event of any breach or threatened breach of this Agreement by one of the Parties, the Parties will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, provided such Party is not in material default hereunder. Such remedies will not be the exclusive remedies for any breach of this Agreement

but will be in addition to all other remedies available at law or equity to each of the Parties. EXCEPT AS PROVIDED IN SECTION 7.2(E), NEITHER PARTY OR ITS AFFILIATES SHALL SEEK OR BE LIABLE FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE, OR SPECULATIVE DAMAGES, INCLUDING, BUT NOT LIMITED TO, LOSS OF REVENUE OR INCOME, OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY RELATING TO ANY BREACH OR ALLEGED BREACH OF THIS AGREEMENT.

Section 9.7 Governing Law. This Agreement shall be governed by and construed in accordance with the law of the State of New York as to all matters, including but not limited to matters of validity, construction, effect, performance and remedies. THE PARTIES HERETO AGREE THAT VENUE IN ANY AND ALL ACTIONS AND PROCEEDINGS RELATED TO THE SUBJECT MATTER OF THIS AGREEMENT SHALL BE IN ▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇ LOCATED IN NEW YORK, NEW YORK AND THE FEDERAL COURTS IN AND FOR THE SOUTHERN DISTRICT OF NEW YORK, WHICH COURTS SHALL HAVE EXCLUSIVE JURISDICTION FOR SUCH PURPOSE, AND THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS AND IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF ANY SUCH ACTION OR PROCEEDING. SERVICE OF PROCESS MAY BE MADE IN ANY MANNER RECOGNIZED BY SUCH COURTS. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 9.8 Compliance with Express Negligence Rule. All releases, disclaimers, limitations on liability, and indemnities in this Agreement shall apply even in the event of the sole, joint, and/or concurrent negligence, strict liability, or other fault of the Party whose liability is released, disclaimed, limited, or indemnified.

Section 9.9 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Section 9.10 Interpretation. The articles, section and schedule headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the Parties and shall not in any way affect the meaning or interpretation of this Agreement.

Section 9.11 Schedules and Exhibits. Except as otherwise provided in this Agreement, all Exhibits and Schedules referred to herein are intended to be and hereby are specifically made a part of this Agreement.

Section 9.12 Entire Agreement. This Agreement and the Confidentiality Agreement, including the Exhibits, Schedules, documents, certificates and instruments referred to herein or therein, embody the entire agreement and understanding of the Parties hereto in respect of the transactions contemplated by this Agreement. There are no restrictions, promises, representations, warranties, covenants or undertakings, other than those expressly set forth or

referred to herein or therein. It is expressly acknowledged and agreed that there are no restrictions, promises, representations, warranties, covenants or undertakings contained in any material made available to Buyer pursuant to the terms of the Confidentiality Agreement. This Agreement supersedes all prior agreements and understandings between the Parties other than the Confidentiality Agreement with respect to such transactions.

Section 9.13 Severability. Any provision of this Agreement that is invalid or unenforceable in any jurisdiction shall be ineffective to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the remaining provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.
