In advance of any proposed assignment by Purchaser to any proposed assignee, Purchaser shall provide to the Company any information concerning such proposed assignment and such proposed assignee as may be reasonably requested by the Company.

SECTION 7.04. Indemnification. (a) The Company hereby indemnifies and holds Purchaser and its Affiliates and any of their respective partners, directors, managers, members, officers, employees and agents (each, a “Purchaser Indemnified Party”) harmless from and against any and all Losses incurred or suffered by any Purchaser Indemnified Party arising out of any breach of any representation or warranty made by the Company in this Agreement.

(c) If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to the preceding paragraphs, the indemnified party shall, promptly after receipt of notice of the commencement of any such claim, demand, action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy of all papers served, if any; provided, that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 7.04 unless, and only to the extent that, such omission results in the forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying party. In case any such action is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7.04 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an indemnified party shall have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party unless the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel. It is agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such indemnified parties. 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. 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.

(a) The relationship between the Company and Purchaser is solely that of seller and purchaser, and neither Purchaser nor the Company has any fiduciary or other special relationship with the other or any of their respective Affiliates.

(b) No officer or employee or agent of Purchaser will be located at the premises of the Company or any of its Affiliates, except in connection with an audit performed pursuant to Section 5.01.

However, the Intercreditor Agreement shall contain an express acknowledgement by the MidCap Credit Facility Agent that it has no security interest in or other rights in respect of the Special Account or any cash held therein.

SECTION 8.05. Control Agreements. (a) The Company agrees, with respect to the Special Account (upon request of Purchaser), to use commercially reasonable efforts to cause the Depository Bank to agree to comply at any time with instructions from Purchaser to the Depository Bank directing the disposition of funds from time to time credited to the Special Account, without further consent of the Company, pursuant to a customary deposit account control agreement in form and substance satisfactory to Purchaser. However, Purchaser shall not give any such instructions or withhold any withdrawal rights from the Company, unless a Remedies Event has occurred and is continuing.

(b) Nothing herein is intended to affect or shall be construed as affecting the rights of the MidCap Credit Facility Agent under any deposit account control agreement in favor of it in respect of the Main Account.

SECTION 8.06. Termination or Release. (a) Upon termination of this Agreement in accordance with its terms and payment in full of all Obligations (other than any contingent indemnification obligations with respect to which no claim has been made) owing by the Company to Purchaser, all right, title, and interest in and to the Collateral shall automatically revert to Company and Purchaser will have no further rights in or with respect to the Collateral and all security interests granted pursuant to this Article VIII shall terminate and be released.

(b) Upon the withdrawal of any Excluded Costs or other amounts from the Special Account in accordance with the terms hereof, Purchaser’s security interest in such amounts granted pursuant to Section 8.01(c) shall be automatically terminated and released.

(c) Subject to the Intercreditor Agreement, upon the sale, lease, transfer, assignment or other disposition (a “Transfer”) of any assets of the Company (other than the Assigned Interests and the Assigned Interest Related Collateral) permitted under the MidCap Credit Facility, all of Purchaser’s security interests in such assets shall be automatically terminated and released.

(d) Subject to the Intercreditor Agreement, at the Company’s request, Purchaser shall subordinate its liens with respect to any such assets or property or terminate and release its liens with respect to any such assets or property (in each case other than the Assigned Interests and the Assigned Interest Related Collateral) subject to any Permitted Transaction.

(e) Upon the termination of the MidCap Credit Facility (or, if the MidCap Credit Facility is refinanced by a debt facility that is secured by Collateral, upon the termination of such refinancing debt facility), Purchaser’s security interest in all Collateral (other than the Assigned Interests and the Assigned Interest Related Collateral) shall automatically be terminated and released.

(f) In connection with any termination or release pursuant to this Section 8.06, Purchaser shall execute and deliver to the Company all documents that the Company shall reasonably request to evidence such termination or release. Purchaser further agrees that with respect to any deposit account (other than the Special Account) over which it has control, it shall not give any instruction to the applicable bank until a Remedies Event has occurred and is continuing.

SECTION 9.01. Remedies. If any Remedies Event shall occur and be continuing, subject to the terms of the Intercreditor Agreement, Purchaser may exercise all rights and remedies of a secured party under the UCC or under any other applicable law and in equity, provided that Purchaser shall exercise any such remedy against the Special Account prior to the exercise of any such remedy against any other Collateral.

SECTION 9.02. Acceleration. If any Remedies Event shall occur and be continuing, subject to the terms of the Intercreditor Agreement, upon notice to the Company, Purchaser may declare all Minimum Quarterly Payments required to be paid by the Company from the date of such Remedies Event until the expiration of the Minimum Annual Payment Period to be due and payable forthwith, whereupon the same shall immediately become due and payable.
