(b) Each Purchaser agrees, severally and not jointly, to indemnify and hold harmless Acquisition (and, after the Merger, the Company), its directors, its officers and each person, if any, who controls Acquisition (and, after the Merger, the Company) within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from Acquisition (and, after the Merger, the Company) to the Purchasers, but only with reference to information relating to such Purchaser furnished to Acquisition in writing by such Purchaser through you expressly for use in either Memorandum or any amendments or supplements thereto. (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 either paragraph (a) or (b) above, 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 expenses 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 because of 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 18 jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for (i) all Purchasers and all persons, if any, who control any Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and (ii) Acquisition (or, after the Merger, the Company), its directors, its officers and each person, if any, who controls Acquisition (or, after the Merger, the Company) 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 Purchasers and such control persons of the Purchasers, such firm shall be designated in writing by Morgan Stanley & Co. Incorporated. In the case of any such separate firm for Acquisition (or, after the Merger, the Company), and such directors, officers and control persons of Acquisition (or, after the Merger, the Company), such firm shall be designated in writing by Acquisition (or, after the Merger, the Company). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, 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, 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 paragraph (a) or (b) of this Section 7 is unavailable to an indemnified party or insufficient in respect of any 19 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties 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 Acquisition and the Company on the one hand and the Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by Acquisition and the Company and the total discounts and commissions received or realized by the Purchasers in respect thereof, in each case as set forth in the Final Memorandum, bear to the aggregate offering price of such Securities. The relative fault of Acquisition and the Company on the one hand and of the Purchasers 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 Acquisition and the Company or by the Purchasers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Purchasers' respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective amount of Securities they have purchased hereunder, not joint. (e) Acquisition (and, after the Merger, the Company) and the Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by PRO RATA allocation (even if the Purchasers 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 paragraph (d) of 20 this Section 7. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above 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 7, no Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities resold by it in the initial placement of such Securities were offered to investors exceeds the amount of any damages that such Purchaser 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. (f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of Acquisition 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 Purchaser or any person controlling such Purchaser or by or on behalf of Acquisition or the Company, their respective officers or directors or any person controlling Acquisition or the Company and (iii) acceptance of and payment for any of the Securities. The remedies provided for in this Section 7 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. 8. TERMINATION. This Agreement shall be subject to termination by notice given by you to Acquisition, if (a) 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, as the case may be, any of the New York Stock Exchange, the American Stock Exchange or the National Association of Securities Dealers, Inc. (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of 21 hostilities or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and (b) in the case of any of the events specified in clauses (a)(i) through (iv), such event, singly or together with any other such event, makes it, in your judgment, impracticable to market the Securities on the terms and in the manner contemplated in the Final Memorandum. 9. EFFECTIVENESS; DEFAULTING PURCHASERS. 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 Purchasers shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Purchaser or Purchasers agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Securities to be purchased on such date, the other Purchasers shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Purchasers, or in such other proportions as you may specify, to purchase the Securities which such defaulting Purchaser or Purchasers agreed but failed or refused to purchase on such date; PROVIDED that in no event shall the principal amount of Securities that any Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Purchaser. If, on the Closing Date, any one or more of the Purchasers shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Purchaser or Purchasers agreed but failed or refused to purchase is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to you and Acquisition for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Purchaser or of Acquisition. In any such case either you or the Company 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 22 the Final Memorandum or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Purchaser from liability in respect of any default of such Purchaser under this Agreement. If this Agreement shall be terminated by the Purchasers, or any of them, because of any failure or refusal on the part of Acquisition to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason Acquisition shall be unable to perform its obligations under this Agreement, Acquisition will reimburse the Purchasers or such Purchasers 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 Purchasers in connection with this Agreement or the offering contemplated hereunder. 10. COUNTERPARTS. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 11. APPLICABLE LAW. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York. Acquisition hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 11.
