(a) Each of the Issuers and each Subsidiary Guarantor agree, jointly and severally, to indemnify and hold harmless the Initial Purchasers, their directors, affiliates, their officers and each person, if any, who controls such Initial Purchasers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action, that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in the Offering Memorandum (or any amendment or supplement thereto) or any information provided by the Issuers or any Subsidiary Guarantor to any holder or prospective purchaser of Series A Notes pursuant to Section 5(f), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Initial Purchasers furnished in writing to the Issuers by such Initial Purchaser (and not with respect to the information provided by any other Initial Purchaser). (b) The Initial Purchasers agree, severally and not jointly, to indemnify and hold harmless the Issuers and the Subsidiary Guarantors, and their respective directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Issuers or the Subsidiary Guarantors, to the same extent as the foregoing indemnity from the Issuers and the Subsidiary Guarantors to the Initial Purchasers but only with reference to information relating to the Initial Purchaser furnished in writing to the Issuers by such Initial Purchaser expressly for use in the Offering Memorandum and not with respect to the information provided by any other Initial Purchaser. (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the "indemnified party"), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(b), the Initial Purchasers shall not be required to assume the defense of such action pursuant to this Section 8(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Initial Purchasers). Any 24 indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by J.P. Morgan Securities Inc., in the case of the parties indemnified pursuant to Section 8(a), and by the Issuers, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty business days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party shall have failed to comply with such reimbursement request. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the indemnified party. (d) To the extent the indemnification provided for in this Section 8 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Subsidiary Guarantors, on the one hand, and the Initial Purchasers on the other hand from the offering of the Series A 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 25 Issuers and the Subsidiary Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Subsidiary Guarantors, on the one hand and the Initial Purchasers, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Series A Notes (after discounts and commissions received by the Initial Purchasers, but before deducting expenses) received by the Issuers, and the total discounts and commissions received by the Initial Purchasers bear to the total price to investors of the Series A Notes, in each case as set forth in the table on the cover page of the Offering Memorandum. The relative fault of the Issuers and the Subsidiary Guarantors, on the one hand, and 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 Issuers or the Subsidiary Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Issuers and the Subsidiary Guarantors, and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8(d) 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 account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with investigating or defending any matter, including any action, that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 8, the Initial Purchasers shall not be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchasers exceeds the amount of any damages which each Initial 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers' obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective principal amount of Series A Notes purchased by each of the Initial Purchasers hereunder and not joint. (e) 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. 9. Conditions of Initial Purchasers' Obligations. The obligations of each of the Initial Purchasers to purchase the Series A Notes under this Agreement are subject to the satisfaction of each of the following conditions: 26 (a) All the representations and warranties of the Issuers and the Subsidiary Guarantors contained in this Agreement shall be true and correct in all material respects on the Closing Date with the same force and effect as if made on and as of the Closing Date, provided that the representations and warranties qualified by "materiality" shall be true and correct on the Closing Date; (b) On or after the date hereof, there shall not have occurred (i) any downgrading, suspension or withdrawal of, nor shall any notice have been given of any potential or intended downgrading, suspension or withdrawal of, or of any review (or of any potential or intended review) for a possible change that either does not indicate the direction of the possible change or indicates a negative change in, any rating of the Issuers or any Subsidiary Guarantor or any securities of the Issuers or any Subsidiary Guarantor (including, without limitation, the placing of any of the foregoing ratings on credit watch with negative or developing implications or under review with an uncertain or negative direction) by any "nationally recognized statistical rating organization" as such term is defined for purposes of Rule 436(g)(2) under the Act, (ii) any change, nor shall any notice have been given of any potential or intended change, in the outlook for any rating of the Issuers or any Subsidiary Guarantor or any securities of the Issuers or any Subsidiary Guarantor by any such rating organization and (iii) no such rating organization shall have given notice that it has assigned (or is considering assigning) a lower rating to the Notes than that on which the Notes were marketed; (iv) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of J.P. Morgan Securities Inc., be likely to prejudice materially the success of the proposed issue, sale or distribution of the Notes, whether in the primary market or in respect of dealings in the secondary market; (v) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Issuers on any exchange or in the over-the-counter market; (vi) any banking moratorium declared by U.S. Federal or New York authorities; (vii) any major disruption of settlements of securities or clearance services in the United States or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of J.P.

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 Schedule B 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 you 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 2 hereof be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of the Series A Notes without the 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 by all Initial Purchasers and arrangements satisfactory to the Initial Purchasers and the Issuers for purchase of such 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 and the Issuers. In any such case which does not result in termination of this Agreement, either you or the Issuers 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. This Agreement may be terminated at any time on or prior to the Closing Date by the Issuers by written notice to the Initial Purchasers if, there is a failure to obtain any consent or waiver under, or amendment of, the Credit Facility, that is required in order for the issuance of the Notes to not constitute a default thereunder. 35 11.
