-9-

by it thereunder, all in accordance with and pursuant to the terms and provisions thereof, and the Trustee and the Secured Parties shall have no obligation or liability under any thereof by reason of or arising out of the assignment hereunder or any assignment under any other Security Document, nor shall the Trustee or the Secured Parties be required or obligated in any manner, except as herein expressly provided, to perform or fulfill any obligations of the Issuer under or pursuant to any of the Lease Documents, to make any payment, or to make any inquiry as to the nature or sufficiency of any payment received by it, or to present or file any claim or take any action to collect or enforce the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

first, so much of such monies, payments or amounts as shall be required to reimburse the Trustee for its fees and the costs and expenses of foreclosure, realization or suit, if any, and the retaking, holding, preparing for sale or other disposition of the Collateral and, to the extent permitted by applicable law, the reasonable attorneys’ fees and legal expenses incurred by the Trustee shall be distributed to the Trustee;

second, so much of such monies, payments or amounts remaining as shall be required to reimburse the holders of the Secured Obligations for all theretofore unreimbursed payments paid by the then existing or prior holders of Secured Obligations pursuant to any indemnity furnished to the Trustee in respect of the Trustee’s performance hereunder or under any of the other Financing Documents shall be distributed to such holders ratably, without priority of one over the other, in the proportion that the amount of each such unreimbursed payment of each such holder of a Secured Obligation bears to the aggregate amount of all such unreimbursed payments by all such holders of Secured Obligations;

third, so much of such monies, payments or amounts remaining as shall be required to pay the accrued and unpaid interest on the unpaid principal balance of the Secured Obligations, allocated among such Secured Obligations pursuant to Section 3.4, shall be distributed to the holders thereof;

fourth, so much of such monies, payments or amounts remaining as shall be required to pay the unpaid principal balance of the Secured Obligations to the extent such principal amount is then due or has been declared or otherwise becomes due, plus any make-whole amount, breakage costs or other premium due thereon, allocated among such Secured Obligations pursuant to Section 3.4, shall be distributed to the holders thereof;

-12-

or any Indemnified Party for any indemnity obligation of the Issuer hereunder or other losses incurred by them (to the extent specifically made reimbursable hereunder and not previously reimbursed) or other amounts then due to them in accordance with the terms of the Financing Documents, shall be distributed as provided in such notice, or if there are insufficient funds remaining in the Collection Account for such distribution, such remaining amounts shall be distributed, ratably, without priority of one such holder over another in the proportion that the amount then owed to such holder bears to the aggregate amount of all such obligations which are then due and payable; and

sixth, the balance, if any, of such monies, payments or amounts after all Secured Obligations have been fully, finally and indefeasibly paid in cash when due or declared due in accordance with the Financing Documents, shall be distributed to the Issuer or its assigns or as otherwise may be required by law; provided that any such monies, payments or amounts shall be distributed to the Issuer at any time that the requirements of Section 3.8(a) have been satisfied.

Unless otherwise expressly provided in this Indenture, any income realized as a result of any such Permitted Investment, net of the Trustee’s reasonable fees and expenses in making such Permitted Investment, shall be held and applied by the Trustee in the same manner as the principal amount of such Permitted Investment is to be applied and any losses, net of earnings and such reasonable fees and expenses, shall be charged against the principal amount invested. The Trustee shall not be liable for any loss resulting from any investment required to be made by it under this Indenture other than by reason of its willful misconduct or gross negligence, and any such investment may be sold (without regard to its maturity) by the Trustee without instructions whenever the Trustee reasonably believes that such sale is necessary to make a distribution required by this Indenture; provided that the Trustee shall be entitled to seek instruction from the Issuer as to which investment should be sold.

Notwithstanding the foregoing or any provision in any Financing Document to the contrary, the Trustee will pay, if so requested in writing by a holder of Secured Obligations, all amounts payable by the Trustee hereunder to such holder, by wire transfer of immediately available funds to an account maintained by such holder with any other bank located in the United States. The Trustee acknowledges that the payment instructions given in Schedule A to the Note Purchase Agreement with respect to the Series A Notes or in a Note Supplement with respect to the Additional Notes or in a similar writing with respect to the Other Secured Loans constitute the written notice required by the preceding sentence to make all payments on such Secured Obligations as provided therein. The Trustee shall institute the transfer of such funds prior to 2:00 p.m. New York, New York time on such due date in accordance with this Section if it has received funds prior to 12:00 p.m. New York, New York time. If the Trustee fails to so institute the transfer of such funds by 2:00 p.m. New York, New York time because it did not receive such funds prior to 12:00 p.m. New York, New York time and such funds are not received by the holders of the Secured Obligations prior to the end of such due date, the only obligation of the Trustee hereunder as a result of such failure shall be to give the Issuer notice of its failure to receive such funds prior to 12:00 p.m. New York, New York time within one (1) Business Day thereof and the Issuer agrees to compensate the holders of the Secured Obligations for the loss of the use of such funds, at a rate of interest equal to the Default Rate.

(b) So long as any of the Secured Obligations remain outstanding, the Issuer will maintain a single agency where the Secured Obligations may be presented for payment, The Issuer hereby designates the principal corporate trust office of the Trustee as its agency for such purpose, and the Trustee hereby accepts such designation. The Issuer will give to the Trustee and the Secured Parties prior written notice of any change of location of any such agency, which shall be located in the United States; provided such agency shall not be changed without the prior written consent of the Required Secured Parties. In case the Issuer shall fail to maintain such agency or shall fail to give such notices of any change of the location thereof, presentations and demands for payment may be made and notice may be served at the address specified for the Issuer in or pursuant to Section 10.3.

Section 3.6.

Method of Payment to Issuer . Any amounts distributed hereunder by the Trustee to the Issuer shall be paid to the Issuer or as the Issuer may otherwise direct by wire transfer of immediately available funds of the type received by the Trustee at such office and to such account or accounts of such entity or entities as shall be designated by notice from the Issuer to the Trustee from time to time.

Section 3.7.

Payments for Which No Application Is Otherwise Provided . Any payments rightfully received by the Trustee for which no provision as to the application thereof is made elsewhere in this Indenture or in any other Financing Document to which the Trustee is a party, shall be deposited in the Collection Account and distributed by the Trustee (a) to the extent received or realized at any time prior to the payment in full of all Secured Obligations, in the

-14-

order of priority specified in Sections 3.1 or 3.2, as appropriate, and (b) to the extent received or realized at any time after payment in full of all such Secured Obligations to the Issuer or as the Issuer may request.

Section 3.8.

Release of Funds to the Issuer; Indemnity Reimbursement Obligations . (a) If as a result of a Payment Event, funds deposited into the Collection Account are being applied pursuant to Section 3.2, and such Payment Event has (i) ceased to exist or (ii) been waived in writing by the Trustee in accordance with this Indenture, then the Issuer may by written notice to the Trustee direct that the funds then remaining in the Collection Account be distributed and applied as set forth in Section 3.1 and the Trustee shall promptly thereafter do so; provided that (x) no Default or Event of Default then exists (or would result therefrom unless waived in writing by the Trustee in accordance with this Indenture) and (y) such request is accompanied by a certificate of a Responsible Officer of the Issuer stating that no Payment Event that would require that funds be held for distribution in accordance with Section 3.2 then exists (or would result from the release of such amounts pursuant to such direction) and setting forth in reasonable detail the basis for such statement.

(b)

In the event any holder of Secured Obligations or any Indemnified Party determines that it has a claim for reimbursement to be paid under clause fourth of Sections 3.1 or clause fifth of Section 3.2 on any Payment Date, such holder or Indemnified Party shall so notify the Trustee in writing not less than ten (10) Business Days prior to such Payment Date, which notice shall include a certification by such holder or Indemnified Party that such reimbursement is due and owing under the Financing Documents, together with a description of the basis for such reimbursement including the reference to the Financing Document and section thereof under which such reimbursement is due.

(i)

protect the Collateral,

-21-

(ii)

instruct or give any notice to the Issuer, or

Section 6.4.

Effect of Sale, Etc . (a) Any sale or sales pursuant to the provisions hereof or of any other Security Document, whether under the power of sale granted thereby or pursuant to any legal proceedings, shall operate to divest the Issuer of all right, title, interest, claim and demand whatsoever, either at law or in equity, of, in and to the Collateral, or any part thereof, so sold, and any Property so sold shall be free and clear of any and all rights of redemption by, through or under the Issuer.

(b)

The receipt by the Trustee, or by any Person authorized under any judicial proceedings to make any such sale, of the proceeds of any such sale shall be a sufficient discharge to any purchaser of the Collateral, or of any part thereof, sold as aforesaid; and no such purchaser shall be bound to see to the application of such proceeds, or be bound to inquire as to the authorization, necessity or propriety of any such sale. In the event that, at any such sale, any holder of Secured Obligations is the successful purchaser, it may, in paying the purchase price, turn in any of its promissory notes evidencing the Secured Obligations in lieu of cash in the amount which shall, upon distribution of the net proceeds of such sale, be payable thereon, and if the cash amounts so payable thereon shall be less than the amount due therein, said promissory notes shall be returned to the holder or holders thereof after a notation of each partial prepayment shall have been made thereon.

Restoration of Rights and Remedies . If the Trustee shall have instituted any proceeding to enforce any right or remedy under this Indenture or under any other Security Document and such proceeding shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and in every such case the Trustee, the Issuer and the holders of the Secured Obligations shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder or under any other Security Document, and thereafter all rights and remedies of the Trustee shall continue as though no such proceeding had been instituted.

Section 6.6.

Application of Sale Proceeds and Deficiency . The proceeds of any exercise of rights with respect to the Collateral, or any part thereof, and the proceeds and the avails of any

-22-

remedy hereunder shall be paid to and applied as described in Section 3.2. In the event that at any time and from time to time the payments under the Facility Lease Agreements then collected by the Trustee and the proceeds of any sale, collection or realization of or upon the Collateral by the Trustee are insufficient to pay all the obligations secured by the Security Documents when due, the Issuer shall be liable for the deficiency, together with interest thereon as provided in the governing Financing Documents or (if no interest is so provided) at such other rate as shall be fixed by applicable law, together with the costs of collection and the reasonable fees and disbursements of any counsel for the Trustee or any holder of the Secured Obligations to collect such deficiency.

Section 6.7.

Cumulative Remedies . No delay or omission of the Trustee or of the holder of any Secured Obligation to exercise any right or power hereunder or under any other Financing Document arising from any Default or Event of Default or failure of performance on the part of the Issuer shall exhaust or impair any such right or power or prevent its exercise during the continuance of such Default or Event of Default. No waiver by the Trustee, or the holder of any Secured Obligation, of any such Default or Event of Default, whether such waiver be full or partial, shall extend to or be taken to affect any subsequent default, or to impair the rights resulting therefrom except as may be otherwise expressly provided herein. No remedy hereunder or under any other Financing Document is intended to be exclusive of any other remedy but each and every remedy shall be cumulative and in addition to any and every other remedy given hereunder or under any other Financing Document or otherwise existing; nor shall the giving, taking or enforcement of any other or additional security, Collateral or guaranty for the payment of the obligations secured under the Security Documents and the other Financing Documents and the other instruments securing the obligations secured thereby operate to prejudice, waive or affect the security thereof or any other instrument securing the obligations secured thereby or any rights, powers or remedies hereunder or under any other Financing Document, nor shall the Trustee or any holder of Secured Obligations be required to first look to, enforce or exhaust such other or additional security, Collateral or guaranty. All covenants, conditions, provisions, warranties, guaranties, indemnities and other undertakings of the Issuer contained in this Indenture or in any document referred to herein or therein or in any agreement supplementary hereto or thereto or in any other Financing Document shall be deemed cumulative to and not in derogation or substitution of any of the terms, covenants, conditions, or agreements of the Issuer herein or therein contained. To the extent of overlap of any Lien or security interest granted under the Security Documents or under any other Financing Document on any particular Collateral, the Trustee may elect to exercise rights and remedies under either or, if appropriate, both of such Liens or security interests.

Section 6.8.

Limitations on Suits . No holder of any Secured Obligation shall have the right to institute any suit, action or proceeding at law or in equity, for the execution of any trust or power granted to the Trustee under this Indenture or any other Security Document or for any other remedy under or upon this Indenture or any other Security Document, unless (a) the Required Secured Parties shall have made written request upon the Trustee to exercise the powers hereinbefore granted or to institute such action, suit or proceeding in its own name; (b) such holder or said holders shall have offered to the Trustee indemnity reasonably satisfactory to it as provided under Section 7.3(f); (c) the Trustee shall have refused or failed to comply with such written request for a period of thirty

-23-

(30) days after such written request shall have been received by it; and (d) during such 30-day period, the Required Secured Parties shall not have given the Trustee a direction inconsistent with the written request. Such notification, request, offer of indemnity, refusal or failure and absence of inconsistent direction are hereby declared, in every case, to be conditions precedent to the exercise by any holder of a Secured Obligation of any remedy hereunder; it being understood and intended that no one or more holders of Secured Obligations shall have any right in any manner whatever by its or their action to enforce any right under this Indenture or any other Security Document, except in the manner herein provided, and that all judicial proceedings to enforce any provision of this Indenture or any other Security Document shall be instituted, had and maintained in the manner herein or in any other Security Document provided and for the equal and proportionate benefit of all holders of the Secured Obligations.

Section 6.9.

Suits for Principal and Interest . Nothing contained in Section 6.8 or in any other provision of this Indenture or in the other Security Documents shall affect or impair the obligation of the Issuer, which is absolute and unconditional, to pay (or cause to be paid from the Collateral as in Article 3 provided) the principal of, any make-whole amount, breakage costs or other premium and interest on, the Secured Obligations to the holders thereof on the dates when due, respectively, and at the place specified in Section 3.5, or affect or impair the right of action, which is also absolute and unconditional, of such holders to institute suits to enforce such payment by virtue of the contract embodied in the respective Financing Documents and to accept and retain payment in respect of any such obligations or to enforce against any other obligor of such obligations any right to have such obligor make such payment and to accept and retain payment from such obligor in respect of any such obligations, provided that nothing in this Section 6.9 shall affect, limit, impair or reduce the requirements of Section 6.11 or Section 6.12 or Article 3 with respect to the disposition of, and sharing of, Collateral and proceeds of Collateral received by a Secured Party or paid to a Secured Party by the Issuer or any other obligor.

Section 6.10.

Waiver by the Issuer . (a) In granting to the Trustee the power to enforce its rights hereunder and under the other Security Documents without prior judicial process or judicial hearing, the Issuer expressly waives, renounces and knowingly relinquishes (to the extent it may lawfully do so) any legal right which might otherwise require the Trustee to enforce its rights by judicial process. In so providing for non-judicial remedies, the Issuer recognizes and concedes that such remedies are consistent with the usage of trade, are responsive to commercial necessity, and are the result of a bargain at arm’s length. Nothing in this Indenture is intended to prevent the Trustee or the Issuer from resorting to judicial process.

(b)

The Issuer by becoming a party to any Security Document (to the extent that it may lawfully do so) hereby covenants that it will not at any time insist upon or plead, or in any manner claim or take the benefit or advantage of, any stay, valuation, appraisal, redemption or extension law now or at any time hereafter in force which, but for this waiver, might be applicable to any sale made under any judgment, order or decree based on any of the Secured Obligations or this Indenture or any other Security Document; and the Issuer by becoming a party to any Security Document (to the extent it may lawfully do so) hereby expressly waives

-24-

and relinquishes all benefit and advantage of any and all such laws and hereby covenants that it will not hinder, delay or impede the execution of any power in any Security Document granted and delegated to the Trustee, but that it will suffer and permit the execution of every such power as though no such law or laws had been made or enacted.

(c)

The Issuer waives any right to require the Trustee or the holders of the Secured Obligations to proceed against any other Person, or to exhaust any Collateral or other security for the obligations secured by the Security Documents and the other Financing Documents and the other instruments securing the obligations secured thereby, or to have any other Person joined with the Issuer in any suit arising out of such obligations or the Financing Documents, or to pursue any other remedy in the Trustee’s or such holders’ power. The Issuer further waives any and all notice of acceptance of this Indenture by any other Person directly or indirectly liable for such obligations from time to time. The Issuer further waives any defense arising by reason of any disability or other defense of any other Person or by reason of the cessation from any cause whatsoever of the liability of any other Person liable for the obligations secured by the Security Documents and the other Financing Documents and the other instruments securing the obligations secured thereby. Until all of such obligations shall have been paid in full, the Issuer shall have no right to subrogation and the Issuer waives the right to enforce any remedy which the Trustee or the holders of the Secured Obligations have or may hereafter have against any other Person liable for such obligations, and the Issuer waives any benefit of any right to participate in any security whatsoever now or hereafter held by the Trustee or the holders of the Secured Obligations. The Issuer authorizes the Trustee and the holders of the Secured Obligations, without notice or demand and without any reservation of rights against the Issuer and without affecting the Issuer’s liability hereunder or on the obligations secured by the Security Documents and the other instruments securing the obligations secured thereby, from time to time to (a) take or hold any Property other than the Collateral from any other Person as security for such obligations, and exchange, enforce, waive and release any or all of such Property, (b) apply such Property and direct the order or manner of sale thereof as the Trustee and the Required Secured Parties may in their discretion determine and (c) renew, extend for any period, accelerate, modify, compromise, settle or release any of the obligations of any other Person in respect of the obligations secured by the Security Documents and the other instruments securing the obligations secured thereby.

Section 6.11.

Sharing .

(a)

Remittance of Proceeds. If

(i)

an Event of Default shall have occurred and be continuing, and

(ii)

a Secured Party shall obtain any payment of proceeds of the Collateral other than through a distribution from the Trustee pursuant to the terms hereof,

then such Secured Party shall, promptly after receipt thereof, notify the Trustee in writing and remit such payment to the Trustee. The Trustee shall, promptly after receipt of such payment, disburse the amount so remitted to it as provided in Section 3.2, in the order of priority set forth therein. Any such payment shall not be deemed to have satisfied any obligations in respect of

-25-

which it was originally received by such Secured Party but rather shall be deemed to have satisfied, to the extent of the amount of such proceeds, the obligations of the Issuer to which such proceeds are applied as provided for in Section 3.2.

(b)

Setoffs, Counterclaims, etc. If

(i)

an Event of Default shall have occurred and be continuing, and

(ii)

a Secured Party shall obtain any amounts through the exercise of a right of banker’s lien, setoff or counterclaim against the Issuer (including any ordinary course application of account balances (by way of set-off, pre-authorized withdrawals, account consolidation or otherwise) to reduce any outstanding principal and to permanently reduce any commitment availability under any Secured Obligation that is in the nature of revolving credit),

then such Secured Party shall, promptly after receipt thereof, notify the Trustee in writing and remit such amounts to the Trustee. The Trustee shall, promptly after receipt of such amounts, disburse the amounts so remitted to it as provided in Section 3.2, in the order of priority set forth therein. Any such amounts shall not be deemed to have satisfied any obligations in respect of which it was originally received by such Secured Party but rather shall be deemed to have satisfied, to the extent of such amounts, the obligations of the Issuer to which such proceeds are applied as provided for in Section 3.2.

(c)

Return of Proceeds. If any Secured Party that has remitted proceeds of Collateral or other amounts to the Trustee pursuant to any one or more of Section 6.11(a) or Section 6.11(b) shall thereafter be required to repay such proceeds or such other amounts to the original payor or obligee thereof, such Secured Party shall (i) notify the Trustee in writing of the same and (ii) have a Lien on the Collateral, prior to the Lien securing the Secured Obligations (except the Lien in favor of the Trustee pursuant hereto), securing the repayment of the proceeds so remitted to the Trustee (less any portion thereof distributed to such Secured Party pursuant to Section 3.2), provided that, upon written request by such Secured Party to the Trustee, the Trustee shall request the Person to whom such proceeds were disbursed to remit such proceeds to the Trustee and such Person shall promptly comply with such request. The failure of the Trustee to make any such request notwithstanding, each Person to whom such proceeds were disbursed shall be and remain obligated to remit such proceeds to the Trustee.

(d)

Sharing of Collateral. Except as otherwise provided in Section 6.11(a) through Section 6.11(c), inclusive, if any Secured Party shall obtain any Property as security for the payment of any Secured Obligation (or as security for the guaranty of any such Secured Obligation) held by it, such Secured Party shall promptly thereafter take such actions as shall be necessary to transfer such property to the Trustee to be held as part of the Collateral, and the Trustee shall apply the proceeds from the disposition of any such Property as provided in Section 3.2, in the order of priority set forth therein.

Section 6.12.

Fees and Expenses . If the Issuer fails to pay when due any amount hereunder or under any other Financing Document, or

-26-

fails to comply with any other provision of any Financing Document in any material respect, the Issuer will pay to the Trustee and each of the Secured Parties, to the extent permitted by applicable law, such further amounts as shall be sufficient to cover the reasonable out-of-pocket costs and expenses, including reasonable attorneys’ fees and expenses, incurred by the Trustee or the Secured Parties (pursuant to their respective rights under this Indenture to exercise remedies in respect of the Collateral) in collecting any such sums or in otherwise analyzing, evaluating, protecting, asserting, defending or enforcing any of their rights as set forth in any Financing Document. Without limiting the generality of the foregoing, the Issuer will pay to the Trustee or the Secured Parties (pursuant to their respective rights under this Indenture to exercise remedies in respect of the Collateral) all reasonable out-of-pocket fees and expenses (including court costs and reasonable attorneys’ fees and expenses) of, or incident to, the enforcement of any of the provisions hereof and all other charges due against the Collateral, including taxes, assessments or Liens upon the Collateral and any reasonable out-of-pocket fees and expenses, including transfer or other taxes, arising in connection with any sale, transfer or other disposition of the Collateral (other than taxes determined by reference to the income of the Trustee or any Secured Party). Such fees and expenses shall be payable on demand together with interest thereon at the Default Rate applicable thereto and the Issuer’s obligation hereunder to pay such expenses shall be treated as a Secured Obligation hereunder.

ARTICLE 7

THE TRUSTEE

Section 7.1.

Grant of Authority; Acceptance of Appointment; Duties and Responsibilities of the Trustee . (a) Each Secured Party and each holder of any Secured Obligations by its acceptance thereof hereby appoints and authorizes the Trustee to execute and deliver this Indenture and to take such action as agent on its behalf and to exercise such powers hereunder and under the other documents executed in connection herewith as are specifically delegated to the Trustee by the terms of this Indenture and to take such other actions as it deems necessary to preserve and protect the security interests granted hereunder, in each case together with such other powers as are reasonably incidental thereto. The Trustee hereby accepts its appointment as “Trustee” hereunder, including its obligations hereunder and under the other documents executed in connection herewith, for the benefit of the Secured Parties, upon the terms expressly set forth herein.

(b)

Subject to Section 7.1(c):

(i)

the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii)

the Trustee may conclusively rely, in good faith, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture or the other Security Documents to which it is a party; but in the case of any such

-27-

certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture.

(c)

In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture for the benefit of the holders of the Secured Obligations, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

(d)

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own gross negligence or its own willful misconduct, or the inaccuracy of any of its representations or warranties made in Section 7.14, except that:

(i)

if the Trustee is a banking corporation, trust company, or banking association, the Trustee shall not be liable for any error of judgment made in good faith by an officer, employee or representative of the Trustee unless it shall be proved that the Trustee was grossly negligent in ascertaining pertinent facts; and

(ii)

the Trustee shall not be liable to the holder of a Secured Obligation with respect to any action taken or omitted to be taken by it, in good faith after an Event of Default shall exist in accordance with the direction of the Required Secured Parties relating to the method and place of conducting any proceeding for any remedy available to the Trustee.

(e)

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(f)

Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.1.

(g)

The Trustee shall give to each holder of Secured Obligations written notice of each and every Default or Event of Default of which one of its Responsible Trust Officers has actual knowledge within three (3) Business Days of obtaining such actual knowledge.

Section 7.2.

Trustee’s Compensation, Expenses and Indemnification . (a) The Issuer covenants and agrees to pay to the Trustee promptly (and in any event within thirty (30) days after receipt of any invoice or other statement or notice) and the Trustee shall be entitled to the fees and expenses as agreed to by the Issuer and the Trustee for all services rendered and expenses incurred by it in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee, which compensation shall not be limited by any provisions of law in regard to the compensation of a trustee of an express trust, and the Issuer

-28-

will pay or reimburse the Trustee promptly (and in any event within thirty (30) days after receipt of any invoice or other statement or notice) for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and its agents) except any such expense, disbursement or advance as may arise from its gross negligence or bad faith or willful misconduct. Subject to subparagraph (c) of this Section 7.3, the Trustee agrees that it shall have no right against any holder of Secured Obligations for the payment of compensation for its services hereunder or any expenses or disbursements incurred in connection with the exercise and performance of its powers and duties hereunder or any indemnification against liability, which it may incur in the exercise and performance of such powers and duties but on the contrary, shall look solely to the Issuer for such payment and indemnification and that it shall have no Lien on or security interest in the Collateral as security for such compensation, expenses, disbursements and indemnification except to the extent provided for in Section 3.2.

(b)

The Issuer shall indemnify and hold harmless the Trustee and each of its officers, directors, employees, investment advisors, affiliates and agents (collectively referred to in this subparagraph (b) as the “Indemnified Persons”) from and against, and reimburse each Indemnified Person for, any and all claims, demands, liabilities, losses, damages, judgments, penalties, out of pocket costs, fees and expenses (including reasonable attorneys’ fees and costs incurred in the investigation, defense and settlement of claims), but not taxes determined by reference to the income of the Trustee (all such items are referred to in this subparagraph (b), collectively, as “Losses”) which may be imposed upon, asserted against, or incurred or paid by any such Indemnified Person by reason of, on account of, or in connection with:

(i)

any bodily injury, death or property damage occurring in or upon or in connection with the use, possession, maintenance, management or operation of the Collateral through any cause whatsoever;

(ii)

any act performed or omitted to be performed under this Indenture or any of the other Security Documents (or other Financing Document to the extent related to the Security Documents) by any such Indemnified Person; or

(iii)

any transaction, suit, action or proceeding arising out of or in any way connected with this Indenture, any other Security Document or the Collateral.

The obligations and liability of the Issuer under this Section 7.2(b) shall survive the foreclosure of, and realization upon, the Collateral and the payment in full of the Secured Obligations and any payment, release or discharge hereof and any or all security interests and Liens in the Collateral, and the resignation or removal of the Trustee. The Issuer shall not be obligated to indemnify any Indemnified Person in respect of any of the foregoing matters if the liability of such Indemnified Person arose out of such Indemnified Person’s gross negligence or willful misconduct. Each Indemnified Person shall, within thirty (30) Business Days after its receipt of written notice of the commencement of any action against it in respect of which indemnity may be sought under this Section 7.2(b), notify the Issuer in writing of such commencement. Unless in such Indemnified Person’s reasonable judgment a conflict of interest between itself and the

-29-

Issuer may exist in respect of such claim, such Indemnified Person, upon (i) written acknowledgement by the Issuer that it will pay any Loss in respect of such claim (subject to the negligence and willful misconduct qualifications set forth above) and (ii) reasonable evidence (including insurance) of its ability to pay such Loss, will permit the Issuer to assume the defense of such claim, with counsel reasonably satisfactory to such Indemnified Person; and if such defense is so assumed, the Issuer shall not enter into any settlement without the consent of such Indemnified Person if such settlement attributes liability to such Indemnified Person (which shall not be unreasonably withheld, conditioned or delayed) and, under the circumstances contemplated hereinabove, the Issuer shall not be subject to any liability for any settlement made without its consent (which shall not be unreasonably withheld, conditioned or delayed).

(c)

To the extent not paid by the Issuer or reimbursed pursuant to Section 3.2, each Secured Party severally agrees to indemnify and hold harmless the Trustee (to the extent not reimbursed or paid by the Issuer as provided herein), pro rata according to the outstanding principal amount of the Secured Obligations held by such Secured Party from time to time, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, fees, costs, expenses or disbursements incurred by the Trustee acting in accordance with the written direction of the Required Secured Parties; provided that no Secured Party shall be required to indemnify the Trustee hereunder to the extent that any claim for indemnification is caused by the gross negligence or willful misconduct of the Trustee.

(d)

The provisions of this Section 7.2 shall survive the resignation or removal of the Trustee and the termination of this Indenture.

Section 7.3.

Certain Rights of the Trustee . (a) The Trustee shall not be responsible for any recitals herein or for insuring all or any portion of the Collateral nor shall the Trustee be bound to ascertain or inquire as to the performance or observance of any covenants, conditions or agreement contained herein. Except in the case of a Default or Event of Default of which a Responsible Trust Officer of the Trustee has actual knowledge, the Trustee shall be deemed to have knowledge of a Default or Event of Default only upon receipt of written notice thereof from the Issuer or any Secured Party; provided, however, that the Trustee shall be deemed to have actual knowledge of any failure to receive (i) payments under the Facility Lease Agreements when due, if the Trustee shall have received a copy of the billing for such payment and (ii) the principal of, any make-whole amount, breakage costs or other premium or interest on, any Secured Obligations on the date any such payment is due and payable to the Trustee.

(b)

Except to the extent expressly provided in Section 7.14, the Trustee does not make any representation, or warranty as to the validity, sufficiency or enforceability of this Indenture, the Security Documents or any other Financing Document or as to the title, operation, merchantability or fitness for use or purpose, value, compliance with specifications, condition, design, quantity, durability or otherwise with respect to any of the Collateral or any substitute therefor. The Trustee shall not be accountable to anyone for the use or application of any of the Secured Obligations or the proceeds thereof or for the use or application of any Collateral or the proceeds thereof which shall be released from the Lien and security interest in favor of the Trustee held in trust under the terms hereof, in accordance with the provisions of this Indenture

-30-

or the Security Documents.

(c)

The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, note or other paper or document believed by it, in good faith, to be genuine and to have been signed or presented by the proper party or parties.

(d)

Any request, direction or authorization by the Issuer shall be sufficiently evidenced by a request, direction or authorization in writing, delivered to the Trustee, and signed in the name of such party by a Responsible Officer of the Issuer; and any resolution of the board of directors of the Issuer or any committee thereof (or equivalent evidence of approval and authorization of action) shall be sufficiently evidenced by a copy of such resolution certified by a Responsible Officer to have been duly adopted and to be in full force and effect on the date of such authentication, and delivered to the Trustee.

(e)

The Trustee may consult with counsel, appraisers, engineers, accountants and other skilled persons to be selected by the Trustee, and the written advice or opinion of any thereof shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(f)

The Trustee shall not be under any obligation to take any action to protect, preserve or enforce any rights or interests in the Collateral or to take any action towards the execution or enforcement of the trusts hereunder or otherwise hereunder, whether on its own motion or on the request of any other Person, if it shall have notified the holders of the Secured Obligations that the same, in the opinion of the Trustee, may involve pecuniary loss, liability or expense, unless the Issuer or one or more holders of Secured Obligations shall offer and furnish reasonable security or indemnity reasonably satisfactory to the Trustee against pecuniary loss, liability and expense to the Trustee (it being acknowledged by the Trustee that the indemnity provided in Section 7.2(c) is satisfactory to the Trustee).

(g)

The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, note or other paper or document, unless requested in writing to do so by the Required Secured Parties. The Trustee shall have no duty to review any financial statement provided to it hereunder.

(h)

The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care.

(i)

The Trustee shall have no obligation to exercise any discretion in the performance of its obligations hereunder and shall only be required to act upon the express written instructions of the Issuer or the holders of the Secured Obligations, as the case may be. If any provision of this Indenture imposes any obligation or determination to be taken or made by the Trustee and such provision does not expressly state who shall instruct or advise the Trustee, then

-31-

such instruction or advice shall be required to be provided to the Trustee by the Required Secured Parties and the Trustee shall promptly request such instructions from the holders of the Secured Obligations.

(j)

IF THE ISSUER DOES NOT PROVIDE THE TRUSTEE WITH EVIDENCE OF THE INSURANCE COVERAGE REQUIRED BY THE FINANCING DOCUMENTS, THE TRUSTEE MAY PURCHASE INSURANCE AT THE ISSUER’S EXPENSE TO PROTECT THE TRUSTEE’S INTERESTS IN THE COLLATERAL. THIS INSURANCE MAY, BUT NEED NOT, PROTECT THE ISSUER’S INTERESTS IN THE COLLATERAL. THE COVERAGE PURCHASED BY THE TRUSTEE MAY NOT PAY ANY CLAIMS THAT THE ISSUER MAKES OR ANY CLAIM THAT IS MADE AGAINST THE ISSUER IN CONNECTION WITH THE COLLATERAL. THE ISSUER MAY LATER CANCEL ANY SUCH INSURANCE PURCHASED BY THE TRUSTEE, BUT ONLY AFTER PROVIDING THE TRUSTEE WITH EVIDENCE THAT THE ISSUER HAS OBTAINED INSURANCE AS REQUIRED BY THE FINANCING DOCUMENTS. IF THE TRUSTEE PURCHASES INSURANCE FOR THE COLLATERAL, THE ISSUER WILL BE RESPONSIBLE FOR THE COSTS OF THAT INSURANCE, INCLUDING INTEREST AND ANY OTHER CHARGES THAT THE TRUSTEE MAY IMPOSE IN CONNECTION WITH THE PLACEMENT OF THE INSURANCE, UNTIL THE EFFECTIVE DATE OF THE CANCELLATION OR EXPIRATION OF THE INSURANCE. THE COSTS OF THE INSURANCE MAY BE ADDED TO THE SECURED OBLIGATIONS SECURED HEREBY. THE COSTS OF THE INSURANCE MAY BE MORE THAN THE COST OF INSURANCE THE ISSUER MAY BE ABLE TO OBTAIN ON ITS OWN.

(k)

The provisions of subparagraphs (c) through (j), inclusive, of this Section 7.3, shall be subject to the provisions of Section 7.1.

(l)

The Trustee need not post any bond for any action taken under this Indenture.

Section 7.4.

Showings Deemed Necessary by the Trustee . Anything else in this Indenture contained to the contrary notwithstanding, the Trustee shall have the right, but shall not be required, to demand in respect of the withdrawal of any cash (other than payments out of the Collection Account pursuant to Sections 3.1 or 3.2), the release of any Property or the subjection of any after acquired Property to any Lien to be held by the Trustee pursuant to the terms of the Security Documents, or any other action whatsoever within the purview hereof, any showings, certificates, opinions, appraisals or other information which the Trustee may deem reasonably necessary or appropriate in addition to the matters required by the terms hereof as a condition precedent to such action.

Section 7.5.

Status of Monies Received . All monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but, if the Trustee is a bank or trust company, need not be segregated in any manner from any other monies, except to the extent required by law, and may be deposited with an Affiliate of the Trustee satisfying the requirements of Section 7.8 or the Trustee itself by the Trustee under such general conditions as may be (if the Trustee is a bank or trust company) prescribed by law and the Trustee’s trust department, and the Trustee shall be under no liability for interest on any monies received by it hereunder except as provided in Section 3.3. If the Trustee is a trust company, banking corporation or banking association or any affiliated corporation thereof, the Trustee or such

-32-

affiliated corporation may be interested in any financial transaction with the Issuer or any of its Affiliates without being liable to account for any profits made thereby; and the Trustee may act as depository or otherwise in respect of other securities of the Issuer or any of its Affiliates, all with the same rights which it would have if not the Trustee; provided that the Trustee shall not exercise any right of setoff against any part of the Collateral.

Section 7.6.

Resignation of the Trustee . The Trustee may resign and be discharged of the trusts hereby created by mailing notice to the Issuer and to all registered holders of Secured Obligations specifying the time and date (not earlier than sixty (60) days after the date of such notice) when such resignation shall take effect. Such resignation shall take effect upon the appointment, qualification and acceptance of a successor trustee as herein provided.

Section 7.7.

Removal of the Trustee . The Trustee may be removed, with or without cause, at any time by the Required Secured Parties by written notice delivered to the Trustee and the Issuer. In addition, so long as no Event of Default or Default exists, the Trustee may be removed, with or without cause, by written notice delivered to the Trustee by the Issuer, provided the Issuer has given the holders of the Secured Obligations not less than 30 days prior written notice thereof requesting the consent of the Required Secured Parties to such removal and the Issuer has received the written consent of the Required Secured Parties to such removal (such consent not to be unreasonably withheld; it being further agreed that failure by the Required Secured Parties to respond to such request for consent within 60 days after the request therefor shall be deemed to constitute consent by the Required Secured Parties to such request so long as the request for such consent indicated that failure to respond would have such an effect pursuant to the terms hereof); and provided further, that the Issuer has theretofore obtained the commitment of a successor trustee that satisfies all the requirements hereof applicable to the Trustee (including Section 7.8) to assume the obligations of the Trustee hereunder and the Issuer has included in its notice to the holders of the Secured Obligations the name of such successor trustee (such appointment being subject, in any event, to the consent of the Required Secured Parties under Section 7.9).

Section 7.8.

Successor Trustee . Each Trustee appointed in succession of the Trustee named in this Indenture, or its successor in trust, shall (i) be a trust company, banking corporation or banking association organized under the laws of the United States of America or of any State thereof, in good standing, (ii) have (or the bank or bank holding company owning all of the outstanding capital stock or share capital of such Person shall have) capital and unimpaired surplus aggregating at least $500,000,000, (iii) be able and willing to accept the trusts upon the terms of this Indenture or other reasonable or customary terms acceptable to the Required Secured Parties, and (iv) be legally licensed and qualified to act as the collateral trustee hereunder in all applicable jurisdictions including each State in which any Collateral is located.

Section 7.9.

Appointment of Successor Trustee . If the Trustee shall have given notice of resignation pursuant to Section 7.6 or if the Trustee shall be removed pursuant to Section 7.7, a successor Trustee may be appointed by the Required Secured Parties (provided that if such successor Trustee would not

-33-

be one of the Predesignated Trustees, and an Event of Default or Default does not then exist, such appointment by the Required Secured Parties shall be with the consent of the Issuer, such consent not to be unreasonably withheld or delayed). If no such appointment shall have been made within twenty-five (25) days after the giving of such notice of resignation or such removal, a successor Trustee may be appointed, upon application of the retiring Trustee, any Secured Party or the Issuer, by any court of competent jurisdiction. During any period during which no such appointment shall have been made, the Required Secured Parties may act as and in the place of the Trustee, and shall have all the rights, remedies, powers, privileges, immunities and indemnities as the Trustee would have in so doing.

Section 7.10.
