Ladies and Gentlemen:

 

MarkWest Energy Partners, L.P., a Delaware limited partnership (the “Partnership”), MarkWest Energy Operating Company, L.L.C., a Delaware limited liability company (the “Operating Company” and, together with the Partnership, the “MarkWest Parties”), and M&R MWE Liberty, LLC, a Delaware limited liability company (the “Selling Unitholder”), hereby confirm their agreement (this “Agreement”) with Citigroup Global Markets Inc. (the “Manager”) as follows:

 

The Partnership owns all of the outstanding capital stock of MarkWest Hydrocarbon, Inc., a Delaware corporation (“MarkWest Hydrocarbon”), and a 1.0% limited liability company interest in MarkWest Energy GP, L.L.C., a Delaware limited liability company (“MarkWest Energy GP”), which serves as the sole general partner of the Partnership. MarkWest Hydrocarbon owns the remaining outstanding limited liability company interests in MarkWest Energy GP. The Partnership conducts its business through the Operating Company, as well as through the other entities identified on Exhibit A attached hereto (the Operating Company and such other entities, other than MarkWest Energy Finance Corporation, a Delaware corporation (“Finance Corp”), are collectively referred to herein as the “Subsidiaries”). The Partnership and the Subsidiaries are collectively referred to as the “MarkWest Entities.”

The Partnership proposes to issue and sell through or to the Manager, as sales agent and/or principal, common units representing limited partner interests in the Partnership (“Common Units”), having an aggregate gross sales price of up to $1,000,000,000 (the “Primary Units”) and the Selling Unitholder proposes to sell through or to the Manager, as sales agent and/or principal, up to 794,761 Common Units (the “Secondary Units” and, together with the Primary Units, the “Units”), from time to time during the term of this Agreement and on the terms set forth in Section 3 of this Agreement. For the avoidance of doubt, the term “Units” as used in this Agreement refers only to the Common Units to be sold pursuant to this Agreement. For purposes of selling the Units through the Manager, the Partnership and the Selling Unitholder each hereby appoint the Manager as their exclusive agent for the purpose of soliciting purchases of the Units from the Partnership or the Selling Unitholder, as applicable, pursuant to this Agreement and the Manager agrees to use its reasonable efforts to solicit purchases of the Units on the terms and subject to the conditions stated herein. Subject to Section 3(f), each of

Certain terms used herein are defined in Section 19.

Any certificate signed by any officer of the Selling Unitholder or by the Custodian on behalf of the Selling Unitholder and delivered to the Manager or counsel for the Manager in connection with this Agreement or any Terms Agreement shall be deemed a representation and warranty of the Selling Unitholder, as to matters covered thereby, to the Manager.

(i)                                     The Units are to be sold on a daily basis or otherwise as shall be agreed to by the Partnership (in the case of Primary Units) or the Custodian (in the case of Secondary Units) and the Manager on any day that:

 

(A)                               is a trading day for the NYSE;

 

(B)                               (1) with respect to Primary Units, the Partnership has instructed the Manager by telephone (confirmed promptly by electronic mail) to make such sales or (2) with respect to Secondary Units, the Custodian has instructed the Manager by telephone (confirmed promptly by electronic mail) to make such sales; and

 

(C)                               (2) with respect to Primary Units, the Partnership has satisfied its obligations under Section 6 of this Agreement or (2) with respect to Secondary Units, the Custodian and the Selling Unitholder have satisfied their obligations under Section 6 of this Agreement.

The Partnership will designate the maximum amount of the Primary Units to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Primary Unit at which such Primary Units may be sold. The Custodian will designate the maximum amount of the Secondary Units to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Secondary Unit at which such Secondary Units may be sold. Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to sell on a particular day all of the Units designated for sale by the Partnership or the Custodian, as applicable, on such day. The gross sales price of the Units sold under this Section 3(a)(i) shall be the market price of the Partnership’s Common Units sold by the Manager under this Section 3(a)(i) on the NYSE at the time of sale of such Units.

 

(ii)                                  The MarkWest Parties and the Selling Unitholder acknowledge and agree that (A) there can be no assurance that the Manager will be successful in selling the Units, (B) the Manager will incur no liability or obligation to the Partnership, the Selling Unitholder or any other person or entity if it does not sell Units for any reason other than a failure by the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Units as required under this Agreement and (C) the Manager shall be under no obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by (x) the Manager and the Partnership or (y) the Manager and the Custodian, as applicable.

 

(iii)                               The Partnership shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its reasonable efforts to sell, any Units not approved for sale by the Board of Directors of MarkWest Energy GP (the “Board”), or an officer of MarkWest Energy GP duly authorized by the Board, and notified by such duly authorized officer to the Manager in writing. The Partnership or the Manager may, upon notice to Partnership or the Manager, as applicable, by telephone (confirmed promptly by electronic mail), suspend the offering of the Units for any reason and at any time; provided, however, that such suspension or termination shall not affect or impair such parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice.

 

(iv)                              The Manager hereby covenants and agrees not to make any sales of the Primary Units on behalf of the Partnership or Secondary Units on behalf of the Selling Unitholder, pursuant to this Section 3(a), other than (A) by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act (such transactions are hereinafter referred to as “Continuous Offerings”) and (B) such other sales of the Units on behalf of the Partnership or the Selling Unitholder, in its capacity as agent of the Partnership or the Selling Unitholder, as

 

18



 

applicable, as shall be agreed by the Partnership, in the case of the Primary Units, or the Custodian or the Selling Unitholder, in the case of the Secondary Units, and the Manager pursuant to a Terms Agreement.

The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Partnership or the Custodian may sell Units to the Manager as principal at a price agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The remaining proceeds, after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”), shall constitute the net proceeds to the Partnership or the Selling Unitholder, as applicable, for such Units (the “Net Proceeds”).

 

(vi)                              The Manager shall provide written confirmation (which may be by facsimile or electronic mail) to the Partnership and the Custodian (to be delivered to the Selling Unitholder) following the close of trading on the NYSE each day in which the Units are sold under this Section 3(a) setting forth the number of the Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Partnership or the Selling Unitholder, as applicable, and the compensation payable by the Partnership or the Selling Unitholder, as applicable, to the Manager with respect to such sales. Such compensation shall be set forth and invoiced in periodic statements from the Manager to the Partnership and/or the Selling Unitholder, with payment to be made by the Partnership or the Selling Unitholder, as applicable, promptly after its receipt thereof.

 

(vii)                           Settlement for sales of the Units pursuant to this Section 3(a) will occur on the third business day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Units sold through the Manager for settlement on such date shall be issued, in the case of the Primary Units, and delivered by the Partnership or delivered by Custodian on behalf of the Selling Unitholder, as applicable (the “Delivering Party”), to the Manager against payment of the aggregate gross sales proceeds less any Transaction Fees for the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units to the Manager’s account at The Depository Trust Company (“DTC”) in return for payments in same day funds delivered to the Delivering Party by federal funds wire transfer to the account designated by the Delivering Party. If the Delivering Party or its transfer agent (if applicable) shall default on its obligation to deliver the Units on any Settlement Date, the Partnership shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay the Manager any compensation to which it would otherwise be entitled absent such default. If the Manager breaches this Agreement by failing to deliver the aggregate gross sales proceeds less any Transaction Fees to the Delivering

 

19



 

Party on any Settlement Date for the Units delivered by the Delivering Party, the Manager will pay the Delivering Party interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to the Manager.

 

(viii)                        At each Applicable Time and Settlement Date and at the First Representation Date and each Representation Date (each as defined in Section 4(k)) thereafter, the MarkWest Parties shall be deemed to have affirmed each representation and warranty of the MarkWest Parties contained in Section 2(i) and the Selling Unitholder shall be deemed to have affirmed each representation and warranty of the Selling Unitholder contained in Section 2(ii), as if, in each case, such representation and warranty were made as of such date (other than those representations and warranties made as of a specific date as specified herein) but modified to incorporate the disclosures contained in the Registration Statement and the Prospectus as amended as of such date. Any obligation of the Manager to use its reasonable efforts to sell the Units on behalf of the Partnership or the Selling Unitholder shall be subject to the continuing accuracy of the representations and warranties of the Partnership and the Selling Unitholder, as applicable, herein (as modified in the manner described above), to the performance by the Partnership and the Selling Unitholder of their obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

 

(b)                                 If either the Partnership wishes to issue and sell the Primary Units or the Custodian wishes to sell the Secondary Units pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement. If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership with respect to the Primary Units or the Custodian with respect to the Secondary Units, wishes to accept amended terms, the Manager, the Partnership and/or the Selling Unitholder will enter into a Terms Agreement setting forth the terms of such Placement. The terms set forth in a Terms Agreement will not be binding on the Partnership, the Selling Unitholder and/or the Manager unless and until the Partnership and/or the Custodian and the Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

 

(c)                                  Each sale of the Units to the Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Units to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Units by the Manager. The commitment of the Manager to purchase the Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Partnership and the Selling Unitholder herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Units to be purchased by the Manager pursuant thereto, the price to be

 

20



 

paid to the Partnership or the Selling Unitholder, as applicable, for such Units, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Units, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Units. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by the Manager.

(e)                                  If any party hereto has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Units, it shall promptly notify the other parties hereto and sales of the Units under this Agreement and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party hereto. The Manager hereby covenants and agrees not to make any sales of the Units on behalf of the Partnership or the Selling Unitholder pursuant to this Section 3, other than (A) directly on or through a national securities exchange or facility thereof, a trading facility of a national securities association, an alternative trading system, an electronic communication network, a “dark pool” or any similar market venue and (B) such other sales of the Units on behalf of the Partnership or the Selling Unitholder in its capacity as agent of the Partnership and the Selling Unitholder, as applicable, as shall be agreed pursuant to a Terms Agreement.

 

(f)                                   The Custodian is authorized to carry out any and all acts on behalf of the Selling Unitholder and make all directions, confirmations and orders to the Manager required to be performed by the Selling Unitholder under the provisions of this Section 3.

(a)                                 During any period when the delivery of a prospectus relating to the Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Act, the Partnership will advise the Manager promptly of any amendment or supplement to the Registration

 

21



 

Statement or the Prospectus which is proposed to be filed (other than any amendment or supplement which does not relate to the sale of the Units and not including any reports or documents and any preliminary or definitive proxy or information statement required to be filed by the Partnership with the Commission in order to comply with the Exchange Act) and to provide the Manager with a reasonable opportunity to review the same. The Partnership has properly completed the Prospectus, in a form approved by the Manager, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Manager of such timely filing. The Partnership will promptly advise the Manager (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement relating to the Units shall have been filed with the Commission, (ii) when, during any period when the delivery of a prospectus (whether physically, deemed to be delivered pursuant to Rule 153, or through compliance with Rule 172 or any similar rule) is required under the Act in connection with the offering or sale of the Units, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement relating to the Units, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

 

(b)                                 If, at any time on or after an Applicable Time but prior to the related Settlement Date or Time of Delivery, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Partnership will (i) notify promptly the Manager so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Manager in such quantities as the Manager may reasonably request.

(c)                                  During any period when the delivery of a prospectus relating to the Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Act, if any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Partnership promptly will (i) notify the Manager of any such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 4, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to the Manager in such quantities as the Manager may reasonably request.

(g)                                  Each of the Partnership and the Manager agree that it has not made and will not make any offer relating to the Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing

(g)                                  The Selling Unitholder shall have furnished or caused to be furnished to the Manager, on every date specified in Section 4(k) of this Agreement, a

 

41



 

certificate of the Selling Unitholder, signed by the Chief Executive Officer or the President and the principal financial officer of the Selling Unitholder, dated as of such date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Disclosure Package and the Prospectus and any supplements or amendments thereto and this Agreement and that, subject to the modification to incorporate the disclosures contained in the Registration Statement, the Disclosure Package and the Prospectus, in each case as amended or supplemented as of such date, the representations and warranties of the Selling Unitholder in this Agreement are true and correct on and as of such date with the same effect as if made on such date, other than those representations and warranties made as of a specific date as specified in this Agreement, and the Selling Unitholder has complied in all material respects (except with respect to agreements and conditions that are qualified by materiality, which shall be true and correct in all respects) with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to such date.

(j)                                    Between the Execution Time and the time of any sale of Units through the Manager, there shall not have been any decrease in the rating of any of the Partnership’s debt securities by any “nationally recognized statistical rating

7.                                      Indemnification and Contribution.

 

(a)                                 The MarkWest Parties agree to indemnify and hold harmless the Manager, the directors, officers, employees and agents of the Manager, each affiliate of the Manager who has participated in the distribution of the Units, each broker dealer affiliate of the Manager and each other affiliate of the Manager within the meaning of Rule 405 under the Act and each person who controls the Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the Base Prospectus, the Prospectus Supplement, any Interim Prospectus Supplement, the Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or

 

43



 

defending any such loss, claim, damage, liability or action; provided, however, that the MarkWest Parties will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Partnership by the Manager or the Selling Unitholder specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the MarkWest Parties may otherwise have.

 

(b)                                 The Selling Unitholder agrees to indemnify and hold harmless the MarkWest Parties, each of MarkWest Energy GP’s directors, each of the officers of the MarkWest Parties who sign the Registration Statement, the Manager, the directors, officers, employees, affiliates and agents of the Manager and each person who controls the MarkWest Parties or the Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the MarkWest Parties to the Manager, but only with reference to written information furnished to the MarkWest Parties by or on behalf of the Selling Unitholder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Selling Unitholder may otherwise have.

 

(c)                                  The Manager agrees to indemnify and hold harmless the MarkWest Parties and the Selling Unitholder, each of MarkWest Energy GP’s and the Selling Unitholder’s directors, each of the officers of the MarkWest Parties or the Selling Unitholder who sign the Registration Statement, and each person who controls the Partnership or the Selling Unitholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the MarkWest Parties to the Manager, but only with reference to written information relating to the Manager furnished to the Partnership or the Selling Unitholder by the Manager specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Manager may otherwise have.

 

(d)                                 Promptly after receipt by any person in respect of which indemnity may be sought pursuant to Section 7(a), 7(b) or 7(c) of notice of the commencement of any action, such person (the “indemnified party”) will, if a claim in respect thereof is to be made against a person against whom such indemnity may be sought under this Section 7 (the “indemnifying party”), notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a), (b) or (c) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a), (b) or (c) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the

 

44



 

indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

 

(e)                                  In the event that the indemnity provided in paragraph (a), (b), (c) or (d) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the MarkWest Parties and the Selling Unitholder, jointly and severally, and the Manager agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the MarkWest Parties, the Selling Unitholder and the Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the MarkWest Parties and the Selling Unitholder on the one hand and by the Manager on the other from the offering of the Units; provided, however, that in no case shall the Manager be responsible for any amount in excess of the compensation as set forth in Section 3(a)(v) of this Agreement, as the case may be, applicable to the Units purchased by the Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the MarkWest Parties and the Selling Unitholder, jointly and severally, and the Manager severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the MarkWest Parties and the Selling Unitholder on the one hand and of the Manager on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the MarkWest Parties and the Selling Unitholder shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Manager shall be deemed to be equal to the total compensation as set forth in Section 3(a)(v) of this Agreement, in each case as determined by this Agreement or any applicable Terms Agreement. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Partnership or the Selling Unitholder on the one hand or the Manager on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such

 

45



 

untrue statement or omission. The MarkWest Parties, the Selling Unitholder and the Manager agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above.

For purposes of this Section 7, each person who controls the Manager within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of the Manager shall have the same rights to contribution as the Manager, and each person who controls the MarkWest Parties or the Selling Unitholder within the meaning of either the Act or the Exchange Act, each officer of the MarkWest Parties or the Selling Unitholder who shall have signed the Registration Statement and each director of MarkWest Energy GP or the Selling Unitholder shall have the same rights to contribution as the MarkWest Parties and the Selling Unitholder, subject in each case to the applicable terms and conditions of this paragraph (e).
