THE COLLATERAL AGENT

Section 5.01. Resignation of Collateral Agent.

(a) The Collateral Agent may resign and be discharged from the performance of its duties hereunder at any time by giving ten (10) days prior written notice to the Issuer and the Holders specifying a date when such resignation shall take effect. The Collateral Agent may be removed at any time with or without cause by an instrument in writing duly executed by or on behalf of the Directing Holders. Notwithstanding anything to the contrary contained herein, no such resignation or removal shall be effective until a successor Collateral Agent shall have been appointed and accepted such appointment in writing, and the other conditions hereof have been satisfied and until all actions necessary to continue the perfection and priority of the security interests in the Pledged Collateral without lapse for the benefit of the successor Collateral Agent and the Holders have been taken. Upon any such notice of resignation or removal, the Requisite Holders jointly shall appoint a successor Collateral Agent hereunder prior to the effective date of such resignation or removal; provided, however, that the Issuer shall have the right to consent to any such appointment by the Holders so long as no Event of Default then exists (which consent by the Issuer shall not be unreasonably withheld, conditioned or delayed).

(b) Upon the making and acceptance of such appointment and the execution and delivery by such successor Collateral Agent of a ratifying instrument pursuant to which such successor Collateral Agent assumes the duties and obligations imposed on the Collateral Agent by the terms of this Agreement, such successor Collateral Agent shall thereupon succeed to and become vested with all of the estate, rights, powers, remedies, privileges, immunities, indemnities, duties and obligations hereby granted to or conferred or imposed upon the Collateral Agent named herein, and one such appointment and designation shall not exhaust the right to appoint and designate further successor Collateral Agents hereunder. The retiring Collateral Agent shall transmit all records pertaining to the Pledged Collateral, shall deliver all Possessory Collateral previously delivered to it and shall pay all Collateral Funds, if any, to the successor Collateral Agent, after making copies of such records and Possessory Collateral as the retiring Collateral Agent deems advisable and after deduction and payment to the retiring Collateral Agent of all fees and expenses (including court costs and attorneys’ fees) payable to, incurred by, or expected to be incurred by the retiring Collateral Agent in connection with the performance of its duties and the exercise of its rights hereunder. After any retiring Collateral Agent’s resignation, the provisions of this Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent under this Agreement.

(c) Any corporation or association into which the Collateral Agent may be merged or converted or with which it may be consolidated, or any corporation or association to which all or substantially all of the escrow business of the Collateral Agent’s corporate trust line of business may be transferred, shall be the Collateral Agent under this Agreement without further act. If no successor Collateral Agent shall be appointed, as aforesaid, or if appointed shall not have accepted its appointment, within sixty (60) days after resignation or removal of the retiring Collateral Agent, then the Collateral Agent or the Holders may apply to any court of competent jurisdiction for the appointment of a successor Collateral Agent, which appointment shall be binding upon the Issuer, the Banks and the Holders.

Section 5.02. Liability of Collateral Agent.

(a) The Collateral Agent undertakes to perform only such duties as are expressly set forth herein and no duties shall be implied. The Collateral Agent shall have no liability under and no duty to inquire as to the provisions of any agreement other than this Agreement and the Pledge Agreement. The Collateral Agent shall not be liable for any action taken or omitted by it in good faith except to the extent that a court of competent jurisdiction determines that the Collateral Agent’s gross negligence or willful misconduct was the primary cause of any loss to the Issuer or the Holders. The Collateral Agent’s sole responsibility shall be for the safekeeping and disbursement of any Possessory Collateral and Collateral Funds, and performing its obligations under the Pledge Agreement, in accordance with the terms of this Agreement and the Pledge Agreement. The Collateral Agent shall have no implied duties or obligations and shall not be charged with knowledge or notice of any fact or circumstance not specifically set forth herein. The Collateral Agent may rely upon any notice, instruction, request or other instrument, not only as to its due execution, validity and effectiveness, but also as to the truth and accuracy of any information contained therein, which the Collateral Agent shall believe to be genuine and to have been signed or presented by the person or parties purporting to sign the same. In no event shall the Collateral Agent be liable for incidental, indirect, special, consequential or punitive damages (including, but not limited to lost profits), even if the Collateral Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. Absent written direction to do so from the Directing Holders and indemnification from the Holders satisfactory to it, the Collateral Agent shall not be obligated to take any legal action or commence any proceeding in connection with the Collateral Funds, any account in which Collateral Funds are deposited, this Agreement or the Pledge Agreement, or to appear in, prosecute or defend any such legal action or proceeding. The Collateral Agent shall not be responsible or liable in any manner for the performance by any other party of their respective obligations under the Pledge Agreement nor shall the Collateral Agent be responsible or liable in any manner for the failure of any other party to honor any of the provisions of this Agreement. The Collateral Agent may consult legal counsel selected by it in the event of any dispute or question as to the construction of any of the provisions hereof or of any other agreement or of its duties hereunder, or relating to any dispute involving any party hereto, and shall incur no liability and shall be fully indemnified from any liability whatsoever in acting in accordance with the opinion or instruction of such counsel. The Issuer shall promptly pay, upon demand, the reasonable fees and expenses of any such counsel.

(b) The Collateral Agent is authorized, in its sole discretion, to comply with orders issued or process entered by any court with respect to the Pledged Collateral and any Collateral Funds, without determination by the Collateral Agent of such court’s jurisdiction in the matter. If any portion of the Pledged Collateral or the Collateral Funds is at any time attached, garnished or levied upon under any court order, or in case the payment, assignment, transfer, conveyance or delivery of any such property shall be stayed or enjoined by any court order, or in case any order, judgment or decree shall be made or entered by any court affecting such property or any part thereof, then and in any such event, the Collateral Agent is authorized, in its sole discretion, to rely upon and comply with any such order, writ, judgment or decree which it is advised by legal counsel selected by it is binding upon it without the need for appeal or other action; and if the Collateral Agent complies with any such order, writ, judgment or decree, it shall not be liable to any of the parties hereto or to any other person or entity by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated.

(c) The Collateral Agent shall in all cases be fully protected in acting or in refraining from acting if such action or refraining from action is in accordance with the written instructions of the Directing Holders.

(d) The Collateral Agent shall not be obligated to file, perfect or record any document or to maintain perfected or recorded any document relating to the Pledged Collateral other than at the direction of the Directing Holders or as expressly authorized in the Pledge Agreement.

Section 5.03. Indemnification of Collateral Agent. From and at all times after the Agreement Date, the Issuer shall, to the fullest extent permitted by law, defend, indemnify and hold harmless the Collateral Agent and each director, officer, employee, agent and affiliate of the Collateral Agent (collectively, the “Indemnified Parties”) against any and all actions, claims (whether or not valid), losses, damages, liabilities, costs and expenses of any kind or nature whatsoever (including without limitation reasonable attorneys’ fees, costs and expenses) incurred by or asserted against any of the Indemnified Parties from and after the Agreement Date, whether direct, indirect or consequential, as a result of or arising from or in any way relating to any claim, demand, suit, action or proceeding (including any inquiry or investigation) by any Person, including without limitation the Issuer or the Holders, whether threatened or initiated, asserting a claim for any legal or equitable remedy against any Person under any statute or regulation, including, but not limited to, any federal or state securities laws, or under any common law or equitable cause or otherwise, arising from or in connection with the negotiation, preparation, execution, performance or failure of performance of this Agreement or any transactions contemplated herein, whether or not any such Indemnified Party is a party to any such action, proceeding, suit or the target of any such inquiry or investigation; provided, however, that no Indemnified Party shall have the right to be indemnified hereunder for any liability finally determined by a court of competent jurisdiction, subject to no further appeal, to have resulted solely from the gross negligence or wilful misconduct of such Indemnified Party. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the Issuer be responsible for paying or indemnifying with respect to the fees and disbursements of more than one law firm to represent the Indemnified Parties in connection with any particular claim, action, proceeding, inquiry or investigation covered by this indemnity. Each Indemnified Party shall, in its sole discretion, have the right to select and employ separate counsel with respect to any action or claim brought or asserted against it, but the fees and expenses of such separate counsel shall be solely the responsibility of such Indemnified Party. The respective obligations of the Issuer and the Holders under this Section 5.03 shall survive any termination of this Agreement and the resignation or removal of the Collateral Agent. The parties agree that neither the payment by the Issuer or the Holders of any claim by the Collateral Agent for indemnification hereunder nor the disbursement of any amounts to the Collateral Agent from the Collateral Funds in respect of a claim by the Collateral Agent for indemnification shall impair, limit, modify, or affect, as between Issuer and Holders, the respective rights and obligations of Issuer, on the one hand, and Holders, on the other hand, hereunder.

Section 5.04. Compensation to Collateral Agent.

(a) Fees and Expenses. The Issuer shall compensate the Collateral Agent for its services hereunder in accordance with Exhibit A attached hereto and, in addition, shall reimburse the Collateral Agent for all of its reasonable out-of-pocket expenses, including reasonable attorneys’ fees, necessary travel expenses, telephone and facsimile transmission costs, postage (including express mail and overnight delivery charges), copying charges and the like. The additional provisions and information set forth on Exhibit A are hereby incorporated by this reference, and form a part of this Agreement. All of the compensation and reimbursement obligations set forth in this Section 5.04(a) shall be payable by the Issuer upon demand by the Collateral Agent. The obligations of the Issuer under this Section 5.04(a) shall survive any termination of this Agreement and the resignation or removal of the Collateral Agent.

(b) Disbursements from Collateral Funds to Pay Collateral Agent. The Collateral Agent is authorized to, and may, disburse to itself from the Collateral Funds, if any, from time to time, the amount of any compensation and reimbursement of out-of-pocket expenses due and payable hereunder (including any amount to which the Collateral Agent is entitled to seek indemnification pursuant to Section 5.03 hereof), if the Issuer shall not have paid such compensation and expenses to the Collateral Agent within sixty (60) days after written demand therefor. The Collateral Agent shall notify the Issuer and the Holders of any disbursement from the Collateral Funds to itself in respect of any compensation or reimbursement hereunder and shall furnish to the Issuer and the Holders copies of all related invoices and other statements. Payment of such compensation and expenses from the Collateral Funds shall not satisfy the Issuer’s obligations to reimburse the Collateral Agent for such amounts, and any amounts so paid by the Issuer after the Collateral Agent has withdrawn Collateral Funds for such purpose shall be deposited by the Collateral Agent forthwith to replenish the Collateral Funds.

(c) Security and Offset. The Holders and the Issuer hereby grant to the Collateral Agent, on behalf of itself and the other Indemnified Parties, a security interest in and lien upon the Collateral Funds to secure all obligations hereunder, and the Collateral Agent shall have the right to offset the amount of any compensation or reimbursement due to the Collateral Agent or any of the other Indemnified Parties (including any claim for indemnification pursuant to Section 5.03 hereof) against the Collateral Funds if the Issuer shall not have paid such compensation and expenses to the Collateral Agent within sixty (60) days after written demand therefor. If for any reason the Collateral Funds available to the Collateral Agent and the Indemnified Parties pursuant to such security interest or right of offset are insufficient to cover such compensation and reimbursement, the Issuer shall promptly pay such amounts to the Collateral Agent and the Indemnified Parties upon receipt of an itemized invoice.

ARTICLE VI.

Section 7.03. Execution of Amendments, Etc. This Agreement may be amended or modified by the Company and the Collateral Agent without the consent of the Holders, in order to cure any defect, ambiguity or inconsistency or to effect any other change which would not, in the reasonable opinion of the Company, adversely affect any of the Holders. Except as provided in the immediately preceding sentence, no amendment, modification, supplement, termination or waiver of or to any provision of this Agreement, nor any consent to any departure by the Issuer from any provision of this Agreement, shall be effective unless the same shall be in writing and signed on behalf of the Requisite Holders (or if the consent of the Directing Holders is expressly required with respect to such matter elsewhere in this Agreement, in the Pledge Agreement or in the 2Q 2012 Notes, then the Directing Holders).
