Each of the MarkWest Entities acknowledges that the statements set forth (i) on the cover page regarding delivery of the Notes and (ii) under the heading “Underwriting,” (A) the sentences related to concessions and (B) the paragraph related to stabilization, in each case contained in any Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriter for inclusion in any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus.

 

(c)                                  In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding.  In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (A) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are

 

33



 

affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (B) the fees and expenses of more than one separate firm (in addition to any local counsel) for the MarkWest Entities, their directors, their officers who sign the Registration Statement and each person, if any, who controls the MarkWest Entities within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred.  In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriter, such firm shall be designated in writing by the Representative. In the case of any such separate firm for the MarkWest Entities, and such directors, officers and control persons of the MarkWest Entities, such firm shall be designated in writing by the Issuers. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement.  No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

 

(d)                                 To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the MarkWest Entities on the one hand and the Underwriters on the other hand from the offering of the Notes or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the MarkWest Entities on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the MarkWest Entities on the one hand and the Underwriters on the other hand in connection with the offering of the Notes shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Notes (before deducting expenses) received by the MarkWest Entities and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the

 

34



 

table on the cover of the Prospectus, bear to the aggregate public offering price of the Notes.  The relative fault of the MarkWest Entities on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the MarkWest Entities or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the principal amount of Notes they have purchased hereunder, and not joint.

 

(e)                                  The MarkWest Entities and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

 

(f)                                    The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the MarkWest Entities contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, or by or on behalf of the MarkWest Entities, each of their officers or directors or any person controlling the MarkWest Entities and (iii) acceptance of and payment for any of the Notes.

 

9.               Termination.   The Underwriters may terminate this Agreement by notice given by the Representative to the Issuers, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Issuers shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any

 

35



 

calamity or crisis that, in the Representative’s judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representative’s judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Notes on the terms and in the manner contemplated in the Pricing Disclosure Package or the Prospectus.

 

10.         Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If, on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase Notes that it has or they have agreed to purchase hereunder on such date, and the principal amount of Notes that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Notes to be purchased pursuant hereto, the other Underwriters shall be obligated severally in the proportions that the principal amount of Notes set forth opposite their respective names in Schedule III bears to the aggregate principal amount of Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Notes that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Notes that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of Notes without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase the Notes and the principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes to be purchased pursuant hereto, and arrangements satisfactory to the Representatives and the Issuers for the purchase of such Notes are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the MarkWest Entities, except that the MarkWest Entities will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 9. In any such case, the Representatives or the MarkWest Entities shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Pricing Disclosure Package, in the Prospectus or in any other documents or arrangements may be effected. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule III hereto that, pursuant to this Section 10, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

 

11.         Reimbursement of Underwriter’s Expenses.   This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If this Agreement shall be terminated by the Underwriters (other than as a result of the events described in Section 9 or Section 10), or any of them because of any failure or refusal on the part of the MarkWest Entities to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the MarkWest Entities shall be unable to perform their respective obligations under this Agreement, the MarkWest Entities will reimburse the Underwriters, or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out of pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

 

36



 

12.         Research Analyst Independence.  The MarkWest Entities acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Issuers and/or the offering that differ from the views of their respective investment banking divisions.  The MarkWest Entities hereby waive and release, to the fullest extent permitted by law, any claims that the MarkWest Entities may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by thier independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the MarkWest Entities by such Underwriters’ investment banking divisions.  The MarkWest Entities acknowledge that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

 

13.         No Fiduciary Duty.  The MarkWest Entities acknowledge and agree that in connection with this offering and sale of the Notes or any other services the Underwriter may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters:  (i) no fiduciary or agency relationship between the MarkWest Entities and any other person, on the one hand, and the Underwriter, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to any of the MarkWest Entities, including, without limitation, with respect to the determination of the public offering price of the Notes, and such relationship between the MarkWest Entities, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the MarkWest Entities shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the MarkWest Entities.  The MarkWest Entities hereby waive any claims that they may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

Additional Information:

 

* We expect that delivery of the notes will be made against payment therefor on or about the expected settlement date specified above, which will be the 7th business day following the date of this term sheet. Under Rule 15c6-1 of the Securities and Exchange Commission under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of this term sheet or the following three business days will be required, by virtue of the fact that the notes initially will settle in T+7, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor.
