(xliv) The Company does not intend to, and does not believe that it will, incur debts beyond its ability to pay such debts as they mature. Upon the issuance of the Notes, the present fair saleable value of the assets of the Company will exceed the amount that will be required to be paid on or in respect of its existing debts and other liabilities (including contingent liabilities) as they become absolute and matured. Upon the issuance of the Notes, the assets of the Company will not constitute unreasonably small capital to carry out its business as now conducted, including the capital needs of the Company, taking into account the projected capital requirements and capital availability.

(xlv) Except pursuant to this Agreement, there are no contracts, agreements or understandings between or among the Company, any of its subsidiaries, Holdings and any other person that would give rise to a valid claim against the Company or any of its subsidiaries or Holdings or the Initial Purchaser for a brokerage commission, finder’s fee or like payment in connection with the issuance, purchase and sale of the Notes.

(xlvi) There exist no conditions that would constitute a default (or an event that with notice or the lapse of time, or both, would constitute a default) under any of the Operative Documents.

The Initial Purchaser acknowledges that the Company and, for purposes of the opinions to be delivered to the Initial Purchaser pursuant to Section 8 hereof, counsel for the Company and counsel for the Initial Purchaser will rely upon the accuracy and truth of the foregoing representations and hereby consents to such reliance.

6. Indemnification.

(a) The Company agrees to indemnify and hold harmless (i) the Initial Purchaser, (ii) each person, if any, who controls the Initial Purchaser 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 Initial Purchaser or any controlling person to the fullest extent lawful, from and against any and all 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 Preliminary Offering Memorandum or the Offering Memorandum, or in any supplement thereto or amendment thereof, 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; provided, however, that the Company will not be liable in any such 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 such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information relating to the Initial Purchaser furnished to the Company in writing by or on behalf of the Initial Purchaser expressly for use therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have, including under this Agreement.

(b) The Initial Purchaser agrees to indemnify and hold harmless (i) the Company, (ii) each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, and (iii) the officers, directors, partners, employees, representatives and agents of the Company 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 Preliminary Offering Memorandum or 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 information relating to the Initial Purchaser furnished to the Company in writing by or on behalf of the Initial Purchaser expressly for use therein; provided, however, that in no case shall the Initial Purchaser be liable or responsible for any amount in excess of the discounts and commissions received by the Initial Purchaser. This indemnity will be in addition to any liability that the Initial Purchaser 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 except to the extent that it has been prejudiced in any material respect by such failure or from any liability that it may otherwise have). 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 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 have reasonably concluded 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 Company, on the one hand, and the Initial Purchaser, 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 Company, any contribution received by the Company from persons, other than the Initial Purchaser, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act) to which the Company and the Initial Purchaser may be subject, in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchaser, on the other hand, from the offering of the Initial 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 Company, on the one hand, and the Initial Purchaser, 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 Company, on the one hand, and the Initial Purchaser, on the other hand, shall be deemed to be in the same proportion as (i) the total proceeds from the offering of Initial

Notes (net of discounts but before deducting expenses) received by the Company and (ii) the discounts and commissions received by the Initial Purchaser, respectively. The relative fault of the Company, on the one hand, and of the Initial Purchaser, 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 Company or the Initial Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to above. Notwithstanding the provisions of this Section 7, (i) in no case shall the Initial Purchaser be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Initial Notes purchased by the Initial Purchaser pursuant to this Agreement exceeds the amount of any damages that the 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 the 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 the Initial Purchaser or any controlling person shall have the same rights to contribution as the Initial Purchaser, and (A) each person, if any, who controls 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 Company shall have the same rights to contribution as 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 claim settled without its prior written consent; provided that such written consent was not unreasonably withheld.

8. Conditions of Initial Purchaser’s Obligations. The obligations of the Initial Purchaser to purchase and pay for the Initial Notes, as provided herein, are subject to the satisfaction of the following conditions:
