The Secured Party shall give the Borrower ten (10) days’ written notice (which the Borrower agrees is reasonable notice within the meaning of the Uniform Commercial Code as in effect in the state or states in which the Collateral is located) of the Secured Party’s intention to make any sale of Collateral. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Secured Party may fix and state in the notice of such sale. At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Secured Party may (in its sole and absolute discretion) determine. The Secured Party shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Secured Party may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from

Page 12

time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Secured Party until the sale price is paid in full by the purchaser or purchasers thereof, but the Secured Party shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. At any public sale made pursuant to this Section, the Secured Party may bid for or purchase, free (to the extent permitted by law) from any right of redemption, stay or appraisal on the part of the Borrower (all said rights being also hereby waived and released to the extent permitted by law), the Collateral or any part thereof offered for sale and may make payment on account thereof by using any claim then due and payable to the Secured Party from the Borrower as a credit against the purchase price, and the Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such, property without further accountability to the Borrower therefor. For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof; the Secured Party shall be free to carry out such sale pursuant to such agreement, and the Borrower shall not be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Secured Party shall have entered into such an agreement all Events of Default shall have been remedied and the Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Secured Party may proceed by a suit or suits at law or in equity to foreclose the Lien created by this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver; and

(ii) the Secured Party, shall, as a matter of right, but subject to applicable Legal Requirements, be entitled to the appointment of a receiver for the Collateral, and the Borrower hereby consents to such appointment, consents to the entry of a decree, and waives notice of any application therefor.

(c) If an Event of Default hereunder has occurred and is continuing, the Secured Party may proceed by an action at law, suit in equity or other appropriate proceeding, but subject to applicable Legal Requirements and the Letter of Credit Documents or the Bond Documents, to protect and enforce its rights, whether for the foreclosure of the Lien of this Security Agreement, or for the specific performance of any agreement contained herein or for an injunction against the violation of any of the terms hereof. In addition, the Secured Party may proceed under Section 12 hereof.

(d) The Secured Party, as attorney-in-fact pursuant to Section 4(a)(i) hereof may, in the name and stead of the Borrower, make and execute all conveyances, assignments and transfers of any Collateral sold in accordance with this Security Agreement. The Borrower shall, if so reasonably requested by the Secured Party, ratify and confirm any sale or sales by executing and delivering to the Secured Party, or to such purchaser or purchasers, all such instruments as may, in the reasonable judgment of the Secured Party, be advisable for such purpose.

6. Remedies Not Exclusive.

The Secured Party shall be entitled to enforce payment of the indebtedness and performance of the Obligations and to exercise all rights and powers under this Security Agreement, any of the other Letter of Credit Documents, the Bond Documents or any other agreements or any laws now or hereafter in force, notwithstanding some or all of the Obligations may now or hereafter be otherwise secured, whether by deed of trust, mortgage, security agreement, pledge, lien, assignment or otherwise. Neither the acceptance of this Security Agreement nor its enforcement, shall prejudice or in any manner affect the Secured Party’s right to realize upon or enforce any other security now or hereafter held by the Secured Party, it being agreed that the Secured Party shall be entitled to enforce this Security Agreement and any other security now or hereafter held by the Secured Party in such order and manner as the Secured Party may determine in its absolute discretion, but subject to the Letter of Credit Documents or the Bond Documents and applicable Legal Requirements. No remedy conferred hereunder or under any other Letter of Credit Documents or the Bond Documents upon or reserved to the Secured Party is intended to be exclusive of any other remedy herein or therein or by law provided or permitted, but each shall be cumulative and shall be in addition to every other remedy given hereunder or thereunder or now or hereafter existing at law or in equity or by statute. Every power or remedy given by any of the Letter of Credit Documents or the Bond Documents to the Secured Party or to which it may otherwise be entitled, may be exercised, concurrently or independently, from time to time and as often as may be deemed expedient by the Secured Party. In no event shall the Secured Party, in the exercise of the remedies provided in this Security Agreement (including without limitation in connection with the assignment of rents to the Secured Party, or the appointment of a receiver and the entry of such receiver onto all or any part of the Facility), be deemed a “mortgagee in possession” or a “pledgee in possession,” and the Secured Party shall not in any way be made liable for any act, either of commission or omission, in connection with the exercise of such remedies other than resulting from its gross negligence or willful misconduct.

7. Application of Collateral and Proceeds.

The proceeds of any sale of, or other realization upon, all or any part of the Collateral shall be applied in the following order of priorities:

(a) first, to pay the expenses of such sale or other realization, including reasonable commissions to the Secured Party’s agents, reasonable attorneys’ fees, and all costs and expenses, liabilities and advances incurred or made by Secured Party in connection therewith;

(b) second, to the satisfaction of the Letter of Credit Obligations owed to the Secured Party and all indebtedness, liabilities and obligations of Borrower owed to the Secured Party under this Security Agreement, in accordance with the terms thereof and hereof; and

(c) third, to the satisfaction of the Bond Obligations and all indebtedness, liabilities and obligations of the Borrower owed to the Issuer, in accordance with the terms of the Bond Documents; and

Page 14

(d) lastly, any surplus remaining after the application described above shall be paid by the Secured Party to the Borrower.

8. Performance by the Secured Party of the Borrower’s Obligations.

If the Borrower fails to perform or comply with any of its agreements contained herein or in any of the other Letter of Credit Documents or the Bond Documents, the Secured Party, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement. The expenses of the Secured Party incurred in connection with actions undertaken as provided in this Section 8, together with interest thereon at a rate per annum equal to the Penalty Rate, from the date of payment by the Secured Party to the date reimbursed by the Borrower, shall be payable by the Borrower to the Secured Party on demand and constitutes part of the Obligations secured hereby.

9. Duty of the Secured Party.

The Secured Party’s sole duty with respect to the custody, safekeeping and physical preservation of any Collateral in its possession, if any, shall be to deal with it in the same manner as the Secured Party deals with similar property for its own account. Neither the Secured Party nor any of its directors, officers, employees, shareholders, partners or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Borrower or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof.

10. Powers Coupled with an Interest.

All powers, authorizations and agencies contained in this Security Agreement are coupled with an interest and are irrevocable until this Security Agreement is terminated and the Liens created hereby are released.

11. Financing Statements.

A carbon, photographic or other reproduction of this Security Agreement shall be sufficient as a financing statement for filing in any jurisdiction. The Borrower hereby authorizes the Secured Party to prepare and file any financing statements and continuations and modifications thereto as the Secured Party deems necessary or appropriate to perfect and maintain its security interest in any of the Collateral under this Security Agreement. For purposes of such financing statement, the Borrower shall be deemed to be the Borrower, and the Secured Party shall be deemed to be the secured party.

12. Security Agreement Under Uniform Commercial Code.

(a) It is the intention of the parties hereto that this Security Agreement shall constitute a security agreement within the meaning of the Uniform Commercial Code. If an Event of Default shall occur hereunder or under any of the Letter of Credit Documents and/or the Bond Documents, then in addition to having any other right or remedy available at law or in equity to each party comprising a Secured Party, the Secured Party may proceed under the

Page 15

applicable Uniform Commercial Code and exercise such rights and remedies as may be provided to a secured party by such Uniform Commercial Code with respect to all or any portion of the Collateral which is personal property (including without limitation taking possession of and selling such property). If the Secured Party shall elect to proceed under the Uniform Commercial Code, then ten (10) days’ notice of sale of the personal property shall be deemed reasonable notice and the reasonable expenses of retaking, holding, preparing for sale, selling and the like incurred by the Secured Party shall include, but not be limited to, attorneys’ fees and legal expenses. At the Secured Party’s request, the Borrower shall assemble such personal property and make it available to the Secured Party at a place designated by the Secured Party which is reasonably convenient to both parties.

(b) The Borrower, upon request by the Secured Party from time to time, shall execute, acknowledge and deliver to the Secured Party, and further authorizes the Secured Party to execute, acknowledge and/or deliver on its behalf one or more separate security agreements, in form satisfactory to the Secured Party, covering all or any part of the Collateral and will further execute, acknowledge and deliver, or cause to be executed, acknowledged and delivered, any financing statement, affidavit, continuation statement or certificate or other document as the Secured Party may request in order to perfect, preserve, maintain, continue or extend the security interest under, and the priority of the Liens granted by, this Security Agreement and such security instrument. The Borrower further agrees to pay to the Secured Party on demand all costs and expenses incurred by the Secured Party in connection with the preparation, execution, recording, filing and re-filing of any such document and all reasonable costs and expenses of any record searches for financing statements the Secured Party shall reasonably require. The filing of any financing or continuation statements in the records relating to personal property or chattels shall not be construed as in any way impairing the right of the Secured Party to proceed against any property encumbered by this Security Agreement.

13. Authority of the Secured Party.

The Borrower acknowledges that the Secured Party shall be conclusively presumed to have full and valid authority with respect to any action taken by the Secured Party or the exercise or non-exercise by the Secured Party of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement and the Borrower shall be under no obligation, or entitlement, to make any inquiry respecting such authority.

14. Notices.

All notices, demands, requests, consents, approvals, certificates or other communications required under this Security Agreement to be in writing shall be sufficiently given and shall be deemed to have been properly given (i) if delivered by hand, when written confirmation of delivery is received by the sender, (ii) three (3) days after the same is mailed by certified mail, postage prepaid, return receipt requested, or (iii) if sent by overnight courier, 24 hours after delivery to such overnight courier, addressed to the person to whom any such notice, demand, request, approval, certificate or other communication is to be given, at the appropriate address for the Principal Office of such person designated below:
