(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless (i) the Issuer and the Company, (ii) each person, if any, who controls the Issuer or the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, and (iii) the respective officers, directors, partners, employees, representatives and agents of the Issuer and the Company or any controlling person to the fullest extent lawful, from and against any losses, liabilities, claims, damages and expenses whatsoever (including but not limited to reasonable attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any investigation or litigation, commenced or threatened, or any claim whatsoever and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (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 Offering Memorandum, 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 light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information relating to such Initial Purchaser furnished to the Issuer and the Company by or on behalf of such Initial Purchaser expressly for use therein; provided, however, that in no case shall any Initial Purchaser be liable or 23 responsible for any amount in excess of the discounts and commissions received by such Initial Purchaser, as set forth in this Agreement. This indemnity will be in addition to any liability that the Initial Purchasers may otherwise have, including under this Agreement. (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability that it may have under this Section 6 or otherwise except to the extent that it has been prejudiced in any material respect by such failure). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume and control the defense thereof with counsel reasonably satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to take charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall be advised by such counsel that there may be defenses available to it or them that are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying party or parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses of counsel shall be borne by the indemnifying parties; provided, however, that the indemnifying party under subsection (a) or (b) above shall only be liable for the legal expenses of one counsel (in addition to any local counsel) for all indemnified parties in each jurisdiction in which any claim or action is brought. Anything in this subsection to the contrary notwithstanding, an indemnifying party shall not be liable for any settlement of any claim or action effected without its prior written consent, provided that such consent was not unreasonably withheld. 7. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 6 is for any reason held to be unavailable from an indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Issuer and the Company, on the one hand, and the Initial Purchasers, on the other hand, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, liabilities, claims, damages and expenses suffered by the Issuer or the Company, any contribution received by the Issuer and the Company from persons, other than the Initial Purchasers, who may also be liable for contribution, including persons who control the Issuer or the Company within the meaning of 24 Section 15 of the Act or Section 20(a) of the Exchange Act) to which the Issuer, the Company and the Initial Purchasers may be subject, in such proportion as is appropriate to reflect the relative benefits received by the Issuer and the Company, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Series A Notes or, if such allocation is not permitted by applicable law or indemnification is not available as a result of the indemnifying party not having received notice as provided in Section 6, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Issuer and the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Company, on the one hand, and the Initial Purchasers, on the other hand, shall be deemed to be in the same proportion as (i) the total proceeds from the offering of Series A Notes (net of discounts and commissions but before deducting expenses) received by the Issuer and the Company and (ii) the discounts and commissions received by the Initial Purchasers, respectively, in each case as set forth in the Offering Memorandum. The relative fault of the Issuer and the Company, on the one hand, and of the Initial 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 the Issuer, the Company or any Initial Purchaser and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Issuer, the Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to above. Notwithstanding the provisions of this Section 7, (i) in no case shall any Initial Purchaser be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Series A Notes purchased by such Initial Purchaser pursuant to this Agreement exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, (A) each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and (B) the respective officers, directors, partners, employees, representatives and agents of any Initial Purchaser or any controlling person shall have the same rights to contribution as any Initial Purchaser, and (A) each person, if any, who controls the Issuer or the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and (B) the respective officers, directors, partners, employees, representatives and agents of the Issuer and the Company shall have the same rights to contribution as the Issuer and the Company, subject in each case to clauses (i) and (ii) of this Section 7. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 7, notify such party or parties from whom contribution may be sought, but the failure to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 7 or otherwise. No party shall be liable for contribution with respect to any action or 25 claim settled without its prior written consent, provided that such written consent was not unreasonably withheld. The Initial Purchasers' obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amount of Series A Notes purchased by each of the Initial Purchasers hereunder and not joint. 8. Conditions of Initial Purchasers' Obligations. The obligations of the Initial Purchasers to purchase and pay for the Series A Notes, as provided herein, shall be subject to the satisfaction of the following conditions: (a) All of the representations and warranties of the Issuer and the Company contained in this Agreement shall be true and correct on the date hereof and on the Closing Date with the same force and effect as if made on and as of the date hereof and the Closing Date, respectively.

(m) Prior to the Closing Date, the Issuer and the Company shall have furnished to the Initial Purchasers such further information, certificates and documents as the Initial Purchasers may reasonably request.

(b) The Initial Purchasers shall have the right to terminate this Agreement at any time prior to the Closing Date by notice to the Issuer and the Company from the Initial Purchasers, without liability (other than with respect to Sections 6 and 7) on the Initial Purchasers' part to the Issuer or the Company if, on or prior to such date, (i) the Company shall have failed, refused or been unable to perform in any material respect any agreement on its part to be performed hereunder, (ii) any other condition to the obligations of the Initial Purchasers hereunder as provided in Section 8 is not fulfilled when and as required in any material respect, (iii) in the reasonable judgment of the Initial Purchasers, any material adverse change shall have occurred since the respective dates as of which information is given in the Offering Memorandum in the condition (financial or otherwise), business, properties, assets, liabilities, prospects, net worth, results of operations or cash flows of the Issuer, the Company, Parent and the Company's Subsidiaries, taken as a whole, including after giving effect to the Mergers, other than as set forth in the Offering Memorandum, or (iv)(A) any domestic or international event or act or occurrence has materially disrupted, or in the opinion of the Initial Purchasers will in the immediate future materially disrupt, the market for the Issuer's or the Company's securities or for securities in general; or (B) trading in securities generally on the New York Stock Exchange, the American Stock Exchange, or the Nasdaq National Market shall have been suspended or materially limited, or minimum or maximum prices for trading shall have been established, or maximum ranges for prices for securities shall have been required, on such exchange or the Nasdaq National Market, or by such exchange or other regulatory body or governmental authority having jurisdiction; or (C) a 29 banking moratorium shall have been declared by federal or state authorities, or a moratorium in foreign exchange trading by major international banks or persons shall have been declared; or (D) there has occurred an outbreak or escalation of hostilities or acts of terrorism involving the United States, or there is a declaration by the United States of a national emergency or war, or there shall have been any other calamity or crisis or any change in political, financial or economic conditions, the effect of which, in any such case, shall be, in the Initial Purchasers' judgment, to make it inadvisable or impracticable to proceed with the offering or delivery of the Series A Notes on the terms and in the manner contemplated in the Offering Memorandum; or (E) there shall have been such a material adverse change in general economic, political or financial conditions or if the effect of international conditions on the financial markets in the United States shall be such as, in the Initial Purchasers' judgment, makes it inadvisable or impracticable to proceed with the delivery of the Series A Notes as contemplated hereby. (c) Any notice of termination pursuant to this Section 11 shall be by telephone or facsimile and, in either case, confirmed in writing by letter. (d) If this Agreement shall be terminated pursuant to any of the provisions hereof (otherwise than pursuant to clause (iv) of Section 11(b), in which case each party will be responsible for its own expenses), or if the sale of the Series A Notes provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Issuer or the Company to perform any agreement herein or comply with any provision hereof, the Issuer and the Company shall reimburse the Initial Purchasers for all out-of-pocket expenses (including the reasonable fees and expenses of the Initial Purchaser's counsel), incurred by the Initial Purchasers in connection herewith. (e) If on the Closing Date any one or more of the Initial Purchasers shall fail or refuse to purchase the Series A Notes which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of the Series A Notes which such defaulting Initial Purchaser or Initial Purchasers, as the case may be, agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Series A Notes to be purchased on such date by all Initial Purchasers, each non-defaulting Initial Purchaser shall be obligated severally, in the proportion which the principal amount of the Series A Notes set forth opposite its name in Exhibit A bears to the aggregate principal amount of the Series A Notes which all the non-defaulting Initial Purchasers, as the case may be, have agreed to purchase, or in such other proportion as Bear, Stearns & Co. Inc. ("Bear Stearns") may specify, to purchase the Series A Notes which such defaulting Initial Purchaser or Initial Purchasers, as the case may be, agreed but failed or refused to purchase on such date; provided that in no event shall the aggregate principal amount of the Series A Notes which any Initial Purchaser has agreed to purchase pursuant to Section 3 hereof be increased pursuant to this Section 11 by an amount in excess of one-ninth of such principal amount of the Series A Notes without the written consent of such Initial Purchaser. If on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase the Series A Notes and the aggregate principal amount of the Series A Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of the Series A Notes to be purchased 30 by all Initial Purchasers and arrangements satisfactory to the Initial Purchasers and the Issuer for purchase of such the Series A Notes are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Initial Purchaser, the Issuer and the Company. In any such case which does not result in termination of this Agreement, either Bear Stearns or the Issuer 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 Offering Memorandum or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of any such Initial Purchaser under this Agreement. 12. Notice.
