Section 2.2 Purchase Price. The aggregate consideration to be paid by the Purchaser for the Membership Interests shall be equal to $126,900,000 (the “Purchase Price”). Each Seller’s respective share of the aggregate Purchase Price payable by the Purchaser for the Membership Interests shall be equal to $63,450,000.

(a) For U.S. federal income tax purposes (and, where applicable for state and local income tax purposes), the Sellers and the Purchaser intend to treat the transfer of the Membership Interests pursuant to this Agreement in the manner specified by Rev. Rul. 99-6, 1999-1 C.B. 432, Situation 2. Accordingly, each Seller intends to treat such transfer as a sale of a partnership interest, and the Purchaser intends to treat such transfer as the purchase of all the assets of the Company.

In the event that the Parties are unable to agree upon a Final Purchase Price Allocation within 40 days of the Closing Date, the Parties may take inconsistent Tax reporting positions with respect to the allocation of the Purchase Price. In the event that the Parties agree upon a Final Purchase Price Allocation, such Final Purchase Price Allocation shall be binding upon all Parties, and neither the Sellers nor the Purchaser shall take any position (whether in connection with audits, Tax Returns, or otherwise) that is inconsistent with the Final Purchase Price Allocation unless required to do so by applicable Tax Law.

As soon as reasonably practicable (and, in the case of filings under the HSR Act, no later than 10 Business Days after the date hereof), the Sellers and the Purchaser shall (i) make all required filings (including any filings required under the HSR Act by the Purchaser or its Affiliates in connection with the transactions contemplated under the Contribution Agreement), prepare all required applications and conduct negotiations with each Governmental Body as to which such filings, applications or negotiations are necessary or appropriate in the consummation of the transactions contemplated hereby, (ii) use commercially reasonable efforts to secure the expiration or termination of any applicable waiting period and clearance or approval by any relevant Governmental Body with respect to this Agreement and the other Transaction Agreements as promptly as is reasonably practicable (including by refraining from acquiring or seeking to acquire any entity or assets (other than pursuant to the transactions contemplated by this Agreement) that would present a material risk of delaying or making it more difficult to secure such expiration or termination of the notice or waiting periods, clearance or approval with respect to the transactions contemplated by this Agreement or the other Transaction Agreements), (iii) provide such information as each may reasonably request to make such filings, prepare such applications and conduct such negotiations, (iv) use commercially reasonable efforts to respond to and resolve any objections as may be asserted by any Governmental Body with respect to this Agreement and the other Transaction Agreements, and (v) use commercially reasonable efforts to contest and resist any action or proceeding instituted (or threatened in writing to be instituted) by any Governmental Body challenging this Agreement and the other Transaction Agreements as violative of any Law. Each Party shall reasonably cooperate with and use all commercially reasonable efforts to assist the other with respect to such filings, applications, and negotiations. Each of the Sellers and the Purchaser shall promptly inform the other Parties of any oral communication, and provide copies of written communications, with any Governmental Body regarding any such filings. No Party shall independently participate in any formal meeting with any Governmental Body in respect of any such filings or other inquiry without giving the other Parties prior notice of the meeting and,

to the extent permitted by such Governmental Body, the opportunity to attend and/or participate. Any Party may, as it deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 6.2 as “outside counsel only.” Such materials and the information contained therein shall be given only to the outside legal counsel of such Party and will not be disclosed by such outside counsel to employees, officers, or directors of such Party, unless express written permission is obtained in advance from the source of the materials.

(a) The initial press release with respect to the execution of this Agreement shall either be a joint press release by the Sellers and the Purchaser, or separate, but concurrent, press releases issued by the Sellers and the Purchaser, in each case to be reasonably agreed upon by the Sellers and the Purchaser. Thereafter, unless consultation is prohibited by applicable Law, no Party shall make any press release or other public announcement with respect to this Agreement, the contents hereof or the transactions contemplated hereby without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided, however, that the foregoing shall not restrict disclosures (i) to the extent required (upon advice of counsel) by applicable securities or other Laws or the applicable rules of any stock exchange having jurisdiction over the Parties or their respective Affiliates, (ii) of the terms of this Agreement by any Seller to its Representatives or (iii) to the extent such Party has been given a reasonable opportunity to review such disclosure prior to its release and no objection is raised.

(b) In connection with the transactions contemplated by this Agreement, and except as otherwise provided in Section 6.3(c) and Section 6.3(d) below, each Seller and its Representatives shall treat the Business Confidential Information as strictly confidential for a period of two years after the date of this Agreement, and shall not sell, trade, publish or otherwise disclose the Business Confidential Information to anyone in any manner whatsoever during such two year period, including by means of photocopy, reproduction or electronic media, without the Purchaser’s prior written consent.

(c) Each Seller may disclose the Business Confidential Information to its Representatives to the extent necessary to exercise or perform its rights under this Agreement or the Transaction Documents; provided, however, that each Seller shall direct any of its Representatives who received the Business Confidential Information under this Agreement to keep the Business Confidential Information strictly confidential and comply with all terms of this Section 6.3.

(d) If a Seller or any of its Representatives is required by Law, Governmental Order, decree, rule or regulation (including without limitation, those of any court, regulatory agency, securities commission or stock exchange) to disclose any Business Confidential Information or if any Person seeks to legally compel (by interrogatories, document requests, subpoena or otherwise) a Seller or any of its Representatives to disclose any Business Confidential Information, such Seller shall, unless prohibited by Law, promptly provide the Purchaser with written notice of the compelled disclosure so the Purchaser may (i) seek a protective order or other remedy at its sole cost (including, without limitation, participation in any Proceeding), or

(ii) waive compliance with the terms of this Section 6.3 in the Purchaser’s sole discretion (but the waiver will be limited to the information required to be disclosed). Such Seller shall be entitled to furnish only the Business Confidential Information as such Seller is advised by its legal counsel that it is legally required to disclose and will use all commercially reasonable efforts to obtain confidential treatment of all Business Confidential Information disclosed.

Section 6.4 Conduct and Preservation of Business. Except as expressly provided in this Agreement or as consented to in writing by the Purchaser (which consent shall not be unreasonably withheld, delayed or conditioned), between the Execution Date and the earlier of the Closing Date and the termination of this Agreement in accordance with Section 9.1, the Sellers will cause the Subject Entities to conduct their operations according to their ordinary course of business and in material compliance with all applicable Laws.

(a) Without limiting the generality of Section 6.4, and except as otherwise expressly provided in this Agreement or the Contribution Agreement, or as set forth on Schedule 6.5, between the Execution Date and the earlier of the Closing Date and the termination of this Agreement in accordance with Section 9.1, the Sellers will not and will cause the Company, the General Partner and BKEP Management not to, in each case without the prior written consent of the Purchaser (which shall not be unreasonably withheld, delayed or conditioned), take, consent to or allow any of the following actions:

(iv) other than in the ordinary course of business consistent with past practice or other than any of the following that will terminate at Closing, (A) cause or permit any Subject Entity to create, incur, guarantee, or assume any indebtedness for borrowed money or otherwise become liable or responsible for the obligations of any other Person; (B) cause or permit any Subject Entity to make any loans, advances, or capital contributions to, or investments in, any other Person; (C) pledge or otherwise encumber the Membership Interests or the Equity Securities of any Subject Entity or BKEP Management; or (D) mortgage or pledge any of the assets of any Subject Entity or BKEP Management, tangible or intangible, or create or suffer to exist any Lien thereupon (other than Permitted Liens);

(v) other than in the ordinary course of business consistent with past practice or as may be required by applicable Law or pursuant to the terms of any employee benefit

plan, policy, program, arrangement or agreement in effect on the date hereof, and provided that the Sellers provide prompt notice to the Purchaser thereof, (i) cause or permit any Subject Entity or BKEP Management to enter into, adopt, materially amend or terminate any employee benefit plan; (ii) materially increase the compensation or fringe benefits of any officer or employee of the General Partner or BKEP Management (other than in connection with new hires or promotions); or (iii) pay to any officer or employee of any Subject Entity or BKEP Management any material benefit not required by any employee benefit plan or other employment or employee benefit plan, program, policy, arrangement or agreement in each case as in effect on the date hereof; provided, further, that this Section 6.5(a)(v) shall not prohibit any amendment to an employee benefit plan that applies broadly and on substantially the same basis to employees of the General Partner and BKEP Management;

(vi) cause or permit any Subject Entity or BKEP Management to acquire, sell, lease, transfer, or otherwise dispose of, directly or indirectly, any assets, except for sales to Persons other than the Sellers or their Affiliates of inventory and excess or obsolete assets in the ordinary course of business consistent with past practice or personal property in the ordinary course of business consistent with past practice that is either replaced by equivalent property or normally consumed in the operation of the businesses of the Subject Entities or BKEP Management;

(vii) cause or permit any Subject Entity or BKEP Management to acquire (by merger, consolidation, or acquisition of stock or assets or otherwise) any corporation, partnership, or other business organization or division thereof;

(viii) cause or permit any Subject Entity or BKEP Management to enter into any lease, contract, agreement, commitment, arrangement, right-of-way, easement or transaction outside the ordinary course of business consistent with past practice, which would constitute a Company Contract or that would be in breach of Section 4.7;

(ix) cause or permit any Subject Entity or BKEP Management to amend, modify, waive any material right or obligation under or transfer any material rights under any Company Contract, other than in the ordinary course of business consistent with past practice;

(b) In the event of an emergency, any Seller or the Company may take such action or actions that are required in their discretion to preserve the businesses of the Subject Entities or the Partnership Entities and shall notify the Purchaser of such action promptly thereafter.

Section 6.6 Further Assurances. After the Closing, the Sellers and the Purchaser agree to, or to cause their Affiliates to, take such further actions and execute, acknowledge and deliver all such further documents as are reasonably requested by the other Party for carrying out the purposes of this Agreement or any document delivered pursuant to this Agreement, including the Transaction Documents and all agreements to be executed by the Parties in connection with the consummation of the transactions contemplated by this Agreement.

(a) The Purchaser covenants and agrees that during the period that commences on the Closing Date and ends on the sixth anniversary of the Closing Date, the Purchaser shall not cause any amendment, modification, waiver or termination of any provision of the Governing Documents of any of the Subject Entities or the Partnership Entities setting forth exculpation from liability or rights to indemnification for officers, directors or managers of any of the Subject Entities or the Partnership Entities, the effect of which would be reasonably expected to affect adversely the rights of any person serving as a member of the board of directors or officer of any of the Subject Entities or the Partnership Entities, existing as of the date of this Agreement under such provisions; provided, however, that the foregoing restriction shall not apply to (i) any such amendment, modification, waiver or termination to the extent required to cause such provisions (or any portion thereof) to comply with applicable Law or (ii) any amendment or termination in connection with any merger, consolidation, restructuring or reorganization as long as the applicable provisions of the Governing Documents of any successor entity in connection with the clause (ii) provide exculpation provisions the effect of which could not reasonably be expected to adversely affect such rights.

(b) The Purchaser covenants and agrees that it shall provide a “tail” or runoff policy for the period that commences on the Closing Date and ends on the sixth anniversary of the Closing Date (the “D&O Tail Policy”), in each case so that any person serving as a director, manager or officer of any of the Subject Entities or the Partnership Entities as of the date of this Agreement and any former director, manager or officer of any of the Subject Entities or the Partnership Entities appointed by any Seller, as applicable, or any Indemnitee (as defined in the Partnership Agreement) as of the date of this Agreement, has coverage thereunder for acts, events, occurrences or omissions occurring or arising at or prior to the Closing to the same extent (including policy limits, exclusions and scope) as such person has coverage for such acts, events, occurrences or omissions under the director and officer insurance or similar policies maintained by the Subject Entities or the Partnership Entities, as applicable, as of the date of this Agreement.

(c) In the event that any Subject Entity, or any Partnership Entity or any of its respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity of such consolidation or merger or, (ii) in one or more series of transactions, directly or indirectly, transfers all or substantially all of its properties and assets to any Person (whether by consolidation, merger or otherwise), then, and in each such case, proper provision shall be made so that such continuing or surviving entity or transferee of such assets or its respective successors and assigns, as the case may be, assume the obligations set forth in this Section 6.7.

Section 6.8 Affiliate Arrangements. Except as disclosed on Schedule 6.8, all liabilities and obligations of the Subject Entities and the Partnership Entities, on the one hand, and the Sellers and their Affiliates (other than the Subject Entities and the Partnership Entities), on the other hand, to each other will automatically terminate in their entirety effective as of the Closing without any further actions by the Parties and thereby be deemed voided, cancelled and discharged in their entirety. Without limiting the generality of the foregoing, except as disclosed on Schedule 6.8 all intercompany accounts among the Subject Entities and the Partnership Entities, on the one hand, and the Sellers and their Affiliates (other than the Subject Entities and the Partnership Entities), on the other hand, that then remain outstanding will be terminated, voided, cancelled and discharged.

Section 6.9 Non-Solicitation. For a period of 12 months from and after the Closing Date, the Purchaser, its Affiliates and each of their respective officers, directors or employees shall not (a) induce or attempt to induce any director, officer or employee of any Seller or its Affiliates (other than the Subject Entities and the Partnership Entities) (collectively, the “Post-Closing Seller Group”) to leave the employ of such member of the Post-Closing Seller Group and (b) in any other way interfere with the relationship between any member of the Post-Closing Seller Group and any employee, officer or director thereof. For a period of 12 months from and after the Closing Date, each Seller, its Affiliates and each of their respective officers, directors or employees shall not (x) induce or attempt to induce any director, officer or employee to leave the employ of the Purchaser or its Affiliates (including after the Closing, the Subject Entities and the Partnership Entities) (the “Post-Closing Purchaser Group”) and (y) in any other way interfere with the relationship between any member of the Post-Closing Purchaser Group and any employee, officer or director thereof. Notwithstanding the foregoing, this Section 6.9 shall not prohibit any Party or its Affiliates from soliciting or hiring any person who responds to a general advertisement or solicitation, including but not limited to advertisements or solicitations through newspapers, trade publications, periodicals, radio or internet database, or efforts by any recruiting or employment agencies, not specifically directed at directors, officers or employees of the other Party or its Affiliates.

(a) In consideration of the substantial expenditures of time, effort and money to be undertaken by the Purchaser in connection with the preparation and execution of this Agreement and its due diligence investigations, the Sellers agree that for the period commencing on the date of this Agreement and terminating upon the earlier of the Closing or the termination of this Agreement in accordance with its terms, the Sellers shall not, and shall not authorize or permit any of their affiliates or any of their representatives to, directly or indirectly, (i) encourage, solicit, initiate, facilitate or continue inquiries regarding an Acquisition Proposal; (ii) enter into discussions or negotiations with, or provide any information to, any person concerning a possible Acquisition Proposal; or (iii) enter into any agreements or other instruments (whether or not binding) regarding an Acquisition Proposal. The Sellers shall immediately cease and cause to be terminated, and shall cause their affiliates and all of their representatives to immediately cease and cause to be terminated, any existing discussions or negotiations with any persons conducted heretofore with respect to, or that could lead to, an Acquisition Proposal.

(b) In addition to the other obligations under this Section 6.10, the Sellers shall promptly (and in any event within three days after receipt thereof by any Seller or its representatives) advise the Purchaser orally and in writing of any Acquisition Proposal, any request for information with respect to any Acquisition Proposal, or any inquiry with respect to or which could reasonably be expected to result in an Acquisition Proposal, the material terms and conditions of such request, Acquisition Proposal or inquiry, and the identity of the person making the same.

(c) The Sellers agree that the rights and remedies for noncompliance with this Section 6.10 shall include having such provision specifically enforced by any court having equity jurisdiction (subject to the limitations set forth in Section 12.4), it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the Purchaser and that money damages would not provide an adequate remedy to the Purchaser.

Section 6.11 Consummation of the Transaction. Each Party shall (i) as promptly as is reasonably practicable, diligently and in good faith, use all commercially reasonable efforts to cause the closing conditions in this Agreement to be satisfied prior to the Termination Date and (ii) coordinate and cooperate with the other Party in providing such information and supplying such assistance as may be reasonably requested by such other Party in connection with the foregoing.

Section 6.12 Series A Consent. Each Seller covenants and agrees that, prior to the Closing, upon the request of the Partnership, such Seller, acting as the holder of 9,156,484 Series A Preferred Units of the Partnership (“Series A Preferred Units”), will provide a written consent approving the issuance of 18,312,968 Series A Preferred Units pursuant to the Contribution Agreement and take any other actions reasonably requested by the Partnership in connection with the approval of the transactions contemplated by the Contribution Agreement and the Unit Repurchase Agreement (as each such agreement may be amended or otherwise modified from time to time).

(a) For a period of 18 months from and after the Closing Date, the Purchaser shall not, and the Purchaser shall cause any Affiliate of Ergon that beneficially owns Series A Preferred Units to not, vote any Series A Preferred Units in favor of any matter (including a merger, consolidation or business combination) that adversely affects any of the rights, preferences and privileges of the Series A Preferred Units or amends or modifies any of the terms of the Series A Preferred Units in any material respect or affects the holders of the Series A Preferred Units disproportionately in relation to the holders of the Common Units of the Partnership (“Common Units”), including, without limitation, those matters identified in Section 5.12(b)(i)-(iv) of the Partnership Agreement (Voting Rights Applicable to Series A Preferred Units).

(b) For a period of 18 months from and after the Closing Date, the Purchaser shall not, and the Purchaser shall cause the General Partner not to, (i) direct, authorize or otherwise permit the Partnership to convert any Series A Preferred Units into Common Units pursuant to Section 5.12(c)(ii) of the Partnership Agreement (Conversion At the Option of the Partnership); or (ii) permit the amendment of the Partnership Agreement in a manner that adversely affects any of the rights of the Sellers or their respective Affiliates under Section 7.12 of the Partnership Agreement (Registration Rights of the General Partner and its Affiliates) in any material respect.

(c) The Sellers shall provide written notice (the “Ownership Report”) to the Purchaser of the number of Series A Preferred Units collectively beneficially owned by the Sellers and any Affiliates of the Sellers as of the first anniversary of the Closing Date (the “Anniversary Date”) within five Business Days of the Anniversary Date (the “Notice Date”). In the event the Ownership Report provides that the Sellers and any Affiliates of the Sellers collectively beneficially own less than 2.5% of the outstanding Series A Preferred Units, the obligations under clauses (a) through (d) of this Section 6.13 shall terminate effective as of the Notice Date.

(d) If the Purchaser or any Affiliate of the Purchaser transfers, assigns or conveys any Series A Preferred Units on or after the Closing Date, it shall require any transferee of such Series A Preferred Units to be subject to the restrictions provided in clauses (a) through (d) hereof in all respects (including the requirements of this sentence). If the Purchaser directly or indirectly transfers, assigns or conveys any Equity Securities of the General Partner on or after the Closing Date, it shall require any transferee of such Equity Securities of the General Partner to be subject to the restrictions provided in clauses (a) through (d) of this Section 6.13 in all respects (including the requirements of this sentence).

(c) by the Purchaser, if any Seller shall have breached any representation or warranty or failed to perform any covenant or agreement set forth in this Agreement or any representation or warranty of either Seller shall have become untrue, in any case such that the conditions set forth in Section 7.3 would not be satisfied (assuming for purposes of this Section 9.1(c) that the references in Section 7.3 to “Closing Date” mean the date of termination pursuant to this Section 9.1(c)), and such breach shall not be curable, or, if curable, shall not have been cured within 30 days after written notice of such breach is given to the Sellers by the Purchaser; provided, however, that the Purchaser may not terminate this Agreement under this Section 9.1(c) if it is then in breach of any representation, warranty, covenant or agreement set forth in this Agreement such that the Sellers would then be entitled to terminate this Agreement under Section 9.1(b) (without giving effect to the proviso in Section 9.1(b));

(d) by the Sellers or the Purchaser, if the Closing does not occur on or before September 30, 2016 (“Termination Date”); provided, however, that the Sellers or the Purchaser, as the case may be, shall not be entitled to terminate this Agreement under this Section 9.1(d) if Closing has not occurred because either of the Sellers or the Purchaser, as the case may be, has materially breached its covenants or agreements hereunder; provided further, that in the event that all conditions in Article 7 have been satisfied other than Section 7.1(b) or Section 7.1(c) as a result of (i) any applicable waiting period under the HSR Act with respect to the transactions contemplated by any of the Transaction Agreements having not terminated or expired, then, neither the Sellers nor the Purchaser may terminate this Agreement under this clause (i) until after an additional 90 days after the Termination Date or (ii) an information statement on Schedule 14C having not yet been distributed to the holders of Series A Preferred Units in accordance with Regulation 14C of the Exchange Act as contemplated by the terms of the Contribution Agreement with respect to any of transactions contemplated under the Transaction Agreements, then, neither the Sellers nor the Purchaser may terminate this Agreement under this clause (ii) until the earlier of (A) an additional 25 days after the distribution of such information statement, and (B) an additional 90 days after the Termination Date;

(a) From and after the Closing, the Purchaser shall indemnify, defend and hold harmless each member of the Seller Group from and against all Damages incurred or suffered by such Persons:

(i) caused by or arising out of or resulting from the Purchaser’s breach of any of the Purchaser’s covenants or agreements contained in this Agreement; or

(ii) caused by or arising out of or resulting from any inaccuracy or breach of any representation or warranty made by the Purchaser contained in Article 5 of this Agreement, in the certificate delivered by the Purchaser at Closing pursuant to Section 8.3(b) or made by Ergon contained in Section 12.17(e), provided that for purposes of determining whether any such representation or warranty is inaccurate or breached, all qualifications as to materiality, material adverse effect and similar qualifications shall be disregarded;

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY MEMBER OF THE SELLER GROUP, but excepting in each case Damages against which the Sellers would be required to indemnify the Purchaser Group under Section 10.1(b) or Section 10.1(c).

(b) From and after the Closing, the Sellers shall, severally and not jointly, indemnify, defend and hold harmless the Purchaser Group from and against all Damages incurred or

suffered by such Persons caused by or arising out of or resulting from any inaccuracy or breach of any representation or warranty made by such Seller contained in Article 3, in the certificates delivered by such Seller at Closing pursuant to Section 8.2(b), made by the CB Funds contained in Section 12.17(a) or made by Vitol Refining contained in Section 12.17(c), provided that for purposes of determining whether any such representation or warranty is inaccurate or breached, all qualifications as to materiality, Material Adverse Effect and similar qualifications shall be disregarded;

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY MEMBER OF THE PURCHASER GROUP, but excepting in each case Damages against which the Purchaser would be required to indemnify the Seller Group under Section 10.1(a).

(c) From and after the Closing, the Sellers shall, severally and not jointly, indemnify, defend and hold harmless the Purchaser Group from and against all Damages incurred or suffered by such Persons:

(i) caused by or arising out of or resulting from such Sellers’ breach of such Sellers’ covenants or agreements contained in this Agreement;

(d) EXCEPT FOR THE REMEDIES CONTAINED IN SECTION 6.10(C), SECTION 12.5 AND CAUSES OF ACTION BASED UPON FRAUD OR AN INTENTIONAL MISREPRESENTATION HEREUNDER, FOLLOWING THE CLOSING, THIS SECTION 10.1 CONTAINS THE PARTIES’ EXCLUSIVE REMEDIES AGAINST EACH OTHER WITH RESPECT TO BREACHES OF THE REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS OF THE PARTIES IN THIS AGREEMENT, AND THE AFFIRMATIONS OF SUCH REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS CONTAINED IN THE CERTIFICATE DELIVERED BY EACH PARTY AT CLOSING PURSUANT TO SECTION 8.2(B) OR SECTION 8.3(B), AS APPLICABLE. EXCEPT FOR THE REMEDIES CONTAINED IN THIS SECTION 10.1, SECTION 6.10(C), SECTION 12.5 AND CAUSES OF ACTION BASED ON FRAUD OR INTENTIONAL

MISREPRESENTATION, FROM AND AFTER THE CLOSING, THE SELLERS AND THE PURCHASER EACH RELEASE, REMISE AND FOREVER DISCHARGE THE OTHERS AND THEIR AFFILIATES AND ALL SUCH PARTIES’ AND THEIR AFFILIATES’ OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS AND OTHER REPRESENTATIVES FROM ANY AND ALL SUITS, LEGAL OR ADMINISTRATIVE PROCEEDINGS, CLAIMS, DEMANDS, DAMAGES, LOSSES, COSTS, LIABILITIES, INTEREST, OR CAUSES OF ACTION WHATSOEVER, IN LAW OR IN EQUITY, KNOWN OR UNKNOWN, WHICH SUCH PARTIES MIGHT NOW OR SUBSEQUENTLY MAY HAVE, BASED ON, RELATING TO OR ARISING OUT OF THIS AGREEMENT, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON; PROVIDED, HOWEVER, THAT THE PURCHASER AND ITS AFFILIATES DO NOT RELEASE (A) ANY ADVISORS OF A SUBJECT ENTITY FOR ANY CLAIMS OF SUCH SUBJECT ENTITY, OR (B) THE SELLERS OR ANY OF THEIR AFFILIATES FOR ANY CLAIMS OF THE SUBJECT ENTITIES OR THE PARTNERSHIP ENTITIES SOLELY WITH RESPECT TO THE CONTRACTS THAT ARE NOT TERMINATED AT CLOSING AS SET FORTH IN SECTION 6.8, INCLUDING SCHEDULE 6.8; AND PROVIDED FURTHER, HOWEVER, THAT THE SELLERS AND THEIR RESPECTIVE AFFILIATES DO NOT RELEASE THE PURCHASER OR ANY OF ITS AFFILIATES OR THE SUBJECT ENTITIES OR THE PARTNERSHIP ENTITIES FOR ANY CLAIMS OF THE SELLERS OR ANY OF THEIR RESPECTIVE AFFILIATES SOLELY WITH RESPECT TO THE CONTRACTS THAT ARE NOT TERMINATED AT CLOSING AS SET FORTH IN SECTION 6.8, INCLUDING SCHEDULE 6.8.

(e) The indemnity of each Party provided in this Section 10.1 shall be for the benefit of and extend to each Person included in the Seller Group and the Purchaser Group, as applicable; provided, however, that any claim for indemnity under this Section 10.1 by any such Person must be brought and administered by a Party to this Agreement. No Indemnified Person (including any Person within the Seller Group and the Purchaser Group) other than the Sellers and the Purchaser shall have any rights against either the Sellers or the Purchaser under the terms of this Section 10.1 except as may be exercised on its behalf by the Purchaser or the Sellers, as applicable, pursuant to this Section 10.1(e). Each of the Sellers and the Purchaser, as applicable, may elect to exercise or not exercise indemnification rights under this Article 10 on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Article 10.

Section 10.2 Indemnification Actions. All claims for indemnification under Section 10.1 shall be asserted and resolved as follows:

(a) For purposes hereof, (i) the term “Indemnifying Person” when used in connection with particular Damages shall mean the Person or Persons having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 10 and (ii) the term “Indemnified Person” when used in connection with particular Damages shall mean the Person or Persons having the right to be indemnified with respect to such Damages by another Person or Persons pursuant to this Article 10.

(b) To make a claim for indemnification under Section 10.1, an Indemnified Person shall notify the Indemnifying Person of its claim under this Section 10.2, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a third Person against the Indemnified Person (a “Third Person Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third Person Claim and shall enclose a copy of all papers (if any) served with respect to the Third Person Claim; provided that the failure of any Indemnified Person to give notice of a Third Person Claim as provided in this Section 10.2 shall not relieve the Indemnifying Person of its obligations under Section 10.1 except to the extent such failure materially prejudices the Indemnifying Person’s ability to defend against the Third Person Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Third Person Claim, the Indemnifying Person shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Third Person Claim under this Section 10.2. If the Indemnifying Person does not notify the Indemnified Person within such 30-day period whether the Indemnifying Person admits or denies its obligation to defend the Indemnified Person, it shall be conclusively deemed to have denied such indemnification obligation hereunder. The Indemnified Person is authorized, prior to and during such 30-day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(d) If the Indemnifying Person admits its obligation, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Third Person Claim. The Indemnifying Person shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Third Person Claim that the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Person may at its own expense participate in, but not control, any defense or settlement of any Third Person Claim controlled by the Indemnifying Person pursuant to this Section 10.2(d). An Indemnifying Person shall not, without the written consent of the Indemnified Person, settle any Third Person Claim or consent to the entry of any judgment with respect thereto which (i) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Person Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person) or (ii) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Person does not admit its obligation or admits its obligation but fails to diligently defend or settle the Third Person Claim, then the Indemnified Person shall have the right to defend against the Third Person Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Person to

admit its obligation and assume the defense of the Third Person Claim at any time prior to settlement or final determination thereof. If the Indemnifying Person has not yet admitted its obligation to provide indemnification with respect to a Third Person Claim, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for 10 days following receipt of such notice to (i) admit in writing its obligation to provide indemnification with respect to the Third Person Claim and (ii) if its obligation is so admitted, reject, in its reasonable judgment, the proposed settlement. If the Indemnified Person settles any Third Person Claim over the objection of the Indemnifying Person after the Indemnifying Person has timely admitted its obligation in writing and assumed the defense of a Third Person Claim, the Indemnified Person shall be deemed to have waived any right to indemnity therefor.

(f) In the case of a claim for indemnification not based upon a Third Person Claim, the Indemnifying Person shall have 30 days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to provide indemnification with respect to such Damages or (iii) dispute the claim for such indemnification. If the Indemnifying Person does not notify the Indemnified Person within such 30-day period that it has cured the Damages or that it disputes the claim for such indemnification, the Indemnifying Person shall be conclusively deemed obligated to provide such indemnification hereunder.

(g) This Section 10.2 shall not apply to Tax Contests, which shall be governed by Section 11.4.

(a) The representations and warranties of the Parties in Article 3, Article 4, Article 5, and the corresponding representations and warranties given in the certificates delivered at Closing pursuant to Section 8.2(b) and Section 8.3(b), as applicable, shall survive the Closing until 15 months after the Closing Date (the “Survival Period”), except that (i) the representations, warranties and acknowledgements, as applicable, in Section 3.1, Section 3.2, Section 3.3, Section 3.4(a), Section 3.6, Section 4.1, Section 4.2(a), Section 4.3, Section 4.4, Section 4.5 (a), (c) and (d), Section 5.1, Section 5.2, Section 5.3(a), Section 5.4 and Section 12.17(a), (c) and (e) (together, the “Core Representations”) shall survive the Closing until 36 months after the Closing Date; (ii) the representations and warranties in Section 4.8 shall survive Closing until 30 days after the applicable statute of limitations closes the taxable year to which the subject Taxes relate; and (iii) the representations and warranties in Section 4.11 shall not survive and shall terminate at the Closing. The covenants and agreements of the Parties in this Agreement shall survive until fully performed in accordance with their terms, except that the covenants and agreements, as applicable, in Section 6.3 and Section 6.6, shall survive for two years. Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date. For purposes of clarification, the Parties acknowledge the fact that a representation or warranty surviving the Closing does not make it a continuing representation or warranty, and no Party shall have a duty after the Closing to advise another Party or its affiliates of any change in circumstances thereto.

(b) The indemnities in Section 10.1(a), Section 10.1(b) and Section 10.1(c) shall terminate as of the last day of the applicable Survival Period, if any, of each respective representation, warranty, covenant or agreement that is subject to indemnification thereunder, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such date. The Purchaser’s indemnification obligations pursuant to Section 10.1(a), and the Sellers’ indemnification obligations pursuant to Section 10.1(c)(i) and Section 10.1(c)(iii) shall not be subject to any deductibles or caps.

(c) The Sellers shall not have any liability for any indemnification under Section 10.1(b) and Section 10.1(c)(ii): (i) for individual claims that do not exceed $100,000 in Damages, (ii) until and unless the aggregate amount of the liability for all Damages thereunder for which Claim Notices are delivered by the Purchaser exceeds $1,125,000 (the “Deductible”), and then only to the extent such Damages exceed the Deductible and (iii) the aggregate amount of the liability for all Damages for which the Sellers shall be liable shall not exceed $11,250,000; provided, however, that the foregoing limitations shall not apply to any indemnification under Section 10.1(b) and Section 10.1(c)(ii) for Damages incurred or suffered by the Purchaser Group related to the Core Representations, representations and warranties in Section 4.8 or Seller Taxes, and the Sellers’ aggregate liability for any such Damages, together with any other indemnification obligations of the Sellers under this Article 10, shall not exceed the Purchase Price.

(d) The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 10 shall be reduced by the amount of insurance proceeds actually received by the Indemnified Person or its Affiliates with respect to such Damages.

Section 10.4 No Duplication. In no event shall any Indemnified Person be entitled to recover any Damages under one Section or provision of this Agreement to the extent of the full amount of such Damages already recovered by such Indemnified Person under this Agreement or any other Transaction Agreement.

(a) For all Pre-Closing Tax Periods that end on or prior to the Closing Date, the Sellers shall, or shall cause the Company, and the General Partner to, prepare all Tax Returns for the Company, and the General Partner (each of the foregoing, a “Pre-Closing Tax Period Return”), the Sellers shall, or shall cause the Company and the General Partner to, timely file such Pre-Closing Tax Period Returns. Each such Pre-Closing Tax Period Return shall be prepared in a manner consistent with past practice, except as otherwise required by applicable Tax Law. The Sellers shall be responsible for the cost and expense of preparing and filing all Pre-Closing Tax Period Returns and shall bear all Taxes for such Pre-Closing Tax Period with respect to the Company and the General Partner whether or not reflected on a Pre-Closing Tax Period Return. The Purchaser shall cause the taxable year of BKEP Management to close as of the Closing Date for U.S. federal income Tax purposes pursuant to Treasury Regulation 1.1502-76(b)(1)(ii) and for state and local income Tax purposes to the extent permissible under

applicable law. Purchaser further agrees to not make an election under Treasury Regulation 1.1502-76(b)(2)(ii)(D) to ratable allocate income or loss of BKEP Management and the so called “next day” rule of the Treasury Regulations 1.1502-76(b)(2)(ii)(B) (or any similar provision of state or local Income Tax law) shall not apply.

(b) For all Straddle Periods, the Purchaser shall cause the Company, and the General Partner to prepare and timely file all Tax Returns for the Company, BKEP Management and the General Partner (each, a “Straddle Period Return”). Each such Tax Return shall be prepared in a manner consistent with past practice, except as otherwise required by applicable Tax Law. The Purchaser shall deliver such Straddle Period Return to the Sellers at least 10 days before the due date of such Tax Return and shall consider in good faith any reasonable comments from the Sellers on such Tax Returns to the extent such comments affect the determination of Seller Taxes. The Purchaser shall be responsible for the cost and expense of preparing and filing the Straddle Period Returns. The Purchaser shall deliver to the Sellers a statement setting forth the Taxes allocable to the portion of the Straddle Period ending on the Closing Date. The Sellers shall bear all Taxes of the Company or the General Partner (whether or not reflected on Tax Returns of the Company and the General Partner) for the portion of any Straddle Period ending on the Closing Date.

Section 11.2 Transfer Taxes. All Transfer Taxes arising from the transactions contemplated by this Agreement shall be borne and paid 50% by the Purchaser and 50% by the Sellers. The Purchaser and the Sellers shall cooperate to file or cause to be filed in a timely manner all necessary documents (including, but not limited to, all Tax Returns) with respect to all such Transfer Taxes. The Sellers shall provide the Purchaser with evidence satisfactory to the Purchaser that such Transfer Taxes have been paid by the Sellers, or if the transactions are exempt from Transfer Taxes upon the filing of an appropriate certificate or other evidence of exemption, the Sellers will timely furnish to the Purchaser such certificate or evidence.

Section 11.3 Subject Entities. With respect to each Subject Entity that is a pass-through entity for U.S. federal income tax purposes and whose taxable year does not close as of the Closing Date, all income, gain, loss or deductions of such Subject Entity shall be allocated between the Purchaser and the Sellers as though the taxable year of such Subject Entity terminated at the close of business on the Closing Date. Notwithstanding this Section 11.3, the Parties acknowledge that the General Partner is subject to U.S. federal income tax reporting by the Partnership, which may use a different convention for prorating partnership items under Section 706 of the Code and the Treasury regulations promulgated thereunder.

Section 11.4 Tax Contests. If, subsequent to the Closing, the Purchaser or a Related Purchaser Party receives notice of any inquiries, claims, assessments, audits or similar events with respect to any Seller Taxes (other than Taxes of the Partnership) (a “Tax Contest”), then promptly after receipt of such notice, the Purchaser shall inform the Sellers of such notice; provided, however, that failure to comply with this provision shall not affect the Purchaser’s right to indemnification hereunder except if, and only to the extent that, as a result of such failure, the Sellers were actually prejudiced. The Sellers shall have the right to control the conduct and resolution of (1) any Tax Contest relating to the Subject Entities’ and the Seller’s Income Tax liabilities attributable solely to a Pre-Closing Tax Period, and (2) any other Tax Contest that relates solely to Seller Taxes; provided, however, that the Sellers shall notify the

Purchaser in writing and keep the Purchaser apprised of the status of same. The Purchaser shall have the right to participate in any Tax Contest controlled by the Sellers at its own expense. The Sellers shall not settle or compromise any Tax Contest (other than Tax Contests relating to the Subject Entities’ or the Seller’s Income Tax liabilities attributable solely to a Pre-Closing Tax Period) without the prior written consent of the Purchaser, which consent shall not be unreasonably delayed, conditioned or withheld. The Purchaser shall control the conduct and resolution of all other Tax Contests that relate to a Pre-Closing Tax Period; provided, however, that the Purchaser shall notify the Sellers in writing and keep the Sellers apprised of the status of same. The Sellers shall have the right to participate in any such Tax Contest that related to a Pre-Closing Tax Period controlled by the Purchaser at their own expense. To the extent such Tax Contest relates to Seller Taxes, the Purchaser shall not settle or compromise any Tax Contest without the prior written consent of the Sellers, which consent shall not be unreasonably delayed, conditioned or withheld.

Section 11.5 Cooperation. The Purchaser and the Sellers agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to the Subject Entities or the Partnership Entities, including, without limitation, access to books and records, as is reasonably necessary for the filing of all Tax Returns by the Purchaser or the Sellers, the making of any election relating to Taxes, the preparation for any audit by any taxing authority, and the prosecution or defense of any claim, suit or proceeding relating to any Tax. The Purchaser and the Sellers shall cooperate fully as and to the extent reasonably requested by the other party in connection with any Tax Contest. Notwithstanding anything to the contrary contained in this Agreement, neither the Purchaser nor any of its Affiliates shall have the right to receive or obtain any information relating to Taxes or Tax Returns of the Sellers or any of their Affiliates (or any of their predecessors) other than information relating solely to the Subject Entities or the Partnership Entities. The Purchaser and the Sellers agree to retain all books and records with respect to Tax matters pertinent to the Subject Entities or the Partnership Entities until the expiration of the relevant statute of limitations (determined without regard to extensions unless the relevant Party has actual knowledge of such extension).

Section 11.6 Straddle Period Allocation. When it is necessary under this Agreement to allocate Taxes, other than Transfer Taxes, between the portion of the Straddle Period ending on or before the Closing Date and the portion of the Straddle Period beginning after the Closing Date, ad valorem, property or other similar Taxes shall be allocated based on a prorated daily basis, Taxes imposed on transactions shall be allocated to the date of the transaction giving rise to the Tax, and all other Taxes shall be allocated based on an interim closing of the books as of the end of the Closing Date.

Section 11.7 Characterization of Certain Payments. The Parties agree that any payments made pursuant to Article 10 or this Article 11 shall be treated for all Tax purposes as an adjustment to the Purchase Price to the extent permitted by applicable Law.

Section 11.8 No Section 338 Election. Purchaser will not make any election under Code Section 338 (or any similar provision under Law) with respect to the acquisition of the Company and its Affiliates.

Section 11.9 Overlap Provisions. In the event of any conflict or overlap between the provisions of this Article 11 and Article 10, the provisions of this Article 11 shall control.

Section 12.1 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original instrument, but all such counterparts together shall constitute but one agreement. Either Party’s delivery of an executed counterpart signature page by facsimile (or electronic .pdf format transmission) is as effective as executing and delivering this Agreement in the presence of the other Party. No Party shall be bound until such time as all of the Parties have executed counterparts of this Agreement.

Section 12.2 Notice. All notices and other communications that are required or may be given pursuant to this Agreement must be given in writing, in English and delivered personally, by courier, by facsimile, by email or by registered or certified mail, postage prepaid, as follows:

Except as otherwise provided herein, all costs and expenses (including legal and financial advisory fees and expenses) incurred in connection with, or in anticipation of, this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expenses.

(a) THIS AGREEMENT AND THE LEGAL RELATIONS BETWEEN THE PARTIES IN CONNECTION HEREWITH SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF OKLAHOMA WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW WHICH WOULD REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

(b) THE PARTIES HEREBY IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA LOCATED IN TULSA, OKLAHOMA AND APPROPRIATE APPELLATE COURTS THEREFROM, AND EACH PARTY HEREBY IRREVOCABLY AGREES THAT ANY DISPUTE, CONTROVERSY OR CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT MAY BE HEARD AND DETERMINED IN SUCH COURTS. THE PARTIES HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAWS, ANY OBJECTION THAT THEY MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH DISPUTE, CONTROVERSY OR CLAIM BROUGHT IN ANY SUCH COURT OR ANY DEFENSE OF INCONVENIENT FORUM FOR THE MAINTENANCE OF SUCH DISPUTE, CONTROVERSY OR CLAIM. 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 APPLICABLE LAW.

(c) EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 12.5 Specific Performance. The Parties acknowledge and agree that a breach of this Agreement would cause irreparable damage to the Purchaser and the Sellers and the Purchaser and the Sellers will not have an adequate remedy at Law. Therefore, the obligations of the Purchaser and the Sellers under this Agreement, including the Sellers’ obligation to sell the Membership Interests to the Purchaser and the Purchaser’s obligation to purchase the Membership Interests from the Sellers, shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which any Party may have under this Agreement or otherwise.

Section 12.6 Waivers. A failure by any Party to comply with any of its obligations, agreements or conditions herein contained may be waived by the Sellers or the Purchaser, as applicable, by an instrument signed by such Party or Parties, as applicable, and expressly identified as a waiver, but not in any other manner. No waiver of, or consent to a change in, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

Section 12.7 Assignment. No Party shall assign all or any part of this Agreement, nor shall any Party assign or delegate any of its rights or duties hereunder, without the prior written consent of the other Parties (which consent may be withheld for any reason) and any assignment or delegation made without such consent shall be void. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns.

Section 12.9 Amendment. This Agreement may be amended or modified only by an agreement in writing executed by all Parties and expressly identified as an amendment or modification.

Section 12.10 No Third Party Beneficiaries. Nothing in this Agreement shall entitle any Person other than the Purchaser and the Sellers to any claims, cause of action, remedy or right of any kind, except the rights expressly provided in Section 6.7 and Section 10.1 to the Persons described therein.

Section 12.11 Construction. The Parties acknowledge that (a) the Sellers and the Purchaser have had the opportunity to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby, (b) this Agreement is the result of arms-length negotiations from equal bargaining positions and (c) the Sellers and the Purchaser and their respective counsel participated in the preparation and negotiation of this Agreement. Any rule of construction that a contract be construed against the drafter shall not apply to the interpretation or construction of this Agreement.

Section 12.12 Limitation on Damages. NOTWITHSTANDING ANYTHING TO THE CONTRARY, NO MEMBER OF THE PURCHASER GROUP OR THE SELLER GROUP SHALL BE ENTITLED TO CONSEQUENTIAL, SPECIAL, INDIRECT (INCLUDING BASED ON LOST PROFITS OR ANY SIMILAR MEASURE), PUNITIVE OR EXEMPLARY DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY (EXCEPT (I) AS REQUIRED TO INDEMNIFY A PARTY FOR THIRD PARTY CLAIMS FOR SUCH DAMAGES OR (II) TO THE EXTENT SUCH DAMAGES ARE OTHERWISE RECOVERABLE UNDER APPLICABLE LAW IN AN ACTION FOR BREACH OF CONTRACT) AND, EXCEPT AS OTHERWISE PROVIDED IN THIS SENTENCE, EACH OF THE PURCHASER AND EACH OF THE SELLERS, FOR ITSELF AND ON BEHALF OF THE PURCHASER GROUP OR THE SELLER GROUP, AS APPLICABLE, HEREBY EXPRESSLY WAIVES ANY RIGHT TO ANY SUCH CONSEQUENTIAL, SPECIAL, INDIRECT, PUNITIVE OR EXEMPLARY DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 12.13 Conspicuous. THE SELLERS AND THE PURCHASER AGREE THAT, TO THE EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE, THE PROVISIONS IN THIS AGREEMENT IN ALL UPPERCASE TYPE OR BOLD-TYPE FONT ARE “CONSPICUOUS” FOR THE PURPOSE OF ANY APPLICABLE LAW.

Section 12.14 Time of Essence. This Agreement contains a number of dates and times by which performance or the exercise of rights is due, and the Parties intend that each and every such date and time be the firm and final date and time, as agreed. For this reason, each Party hereby waives and relinquishes any right it might otherwise have to challenge its failure to meet any performance or rights election date applicable to it on the basis that its late action constitutes substantial performance, to require the other Party to show prejudice, or on any equitable grounds. Without limiting the foregoing, time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date that is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day that is a Business Day.

Section 12.15 Severability. The invalidity or unenforceability of any term or provision of this Agreement in any situation or jurisdiction shall not affect the validity or enforceability of the other terms or provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction and the remaining terms and provisions shall remain in full force and effect, unless doing so would result in an interpretation of this Agreement that is manifestly unjust.

Section 12.16 Release. Except for the obligations of the Parties under this Agreement or any Transaction Document or the Agreements set forth on Schedule 6.8 that will not terminate as of the Closing, for and in consideration of the Membership Interests, in the case of the Purchaser, and the Purchase Price, in the case of the Sellers, effective as of the Closing, (a) the Purchaser shall, and shall cause its Affiliates (including the Subject Entities and Partnership Entities) to, absolutely and unconditionally release, acquit and forever discharge the Sellers and their respective Affiliates, each of the present and former partners, members, equityholders, officers, directors, managers, employees, agents and representatives of any of the foregoing, and each of their respective heirs, executors, administrators, successors and assigns, from any and all costs, expenses, damages, debts, or any other obligations, liabilities and claims whatsoever, whether known or unknown, both in Law and in equity, in each case to the extent arising out of or resulting from the ownership and/or operation of the Subject Entities or the Partnership Entities, or the assets, business, operations, conduct, services, products and/or employees (including former employees) of any of the Subject Entities or the Partnership Entities (and any predecessors), related to any period of time before the Closing Date and (b) the Sellers shall, and shall cause their Affiliates to, absolutely and unconditionally release, acquit and forever discharge each of the Subject Entities and the Partnership Entities and their respective Affiliates, each of the present and former partners, members, equityholders, officers, directors, managers, employees, agents and Representatives of any of the foregoing, and each of their respective heirs, executors, administrators, successors and assigns, from any and all costs, expenses, Damages, debts, or any other obligations,
