Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed. All Existing Letters of Credit shall be deemed to have been issued by the applicable L/C Issuer pursuant hereto, and from and after the Restatement Effective Date shall be subject to and governed by the terms and conditions hereof.

Letter of Credit Collateral Account. The Borrowers hereby agree that they will, from the time a deposit is required pursuant to Section 2.3(a), [Section 9.2(c)], Section 9.3 or [Section 11.9] until the Obligations are satisfied and all Letters of Credit have expired or been terminated or cancelled or as otherwise set forth below, maintain a special collateral account (the “Letter of Credit Collateral Account”) at the Administrative Agent’s office at the address specified pursuant to Section 11.1, in the name of the Borrowers, but under the sole dominion and control, including the exclusive right of withdrawal, of the Administrative Agent, for the benefit of the Revolving Loan Lenders, and in which the Borrowers shall have no interest other than as set forth in this [Section 2.3(l)] or in Section 9.3. Such Letter of Credit Collateral Account shall be funded to the extent required by Section 2.3(a), [Section 9.2(c)], Section 9.3 or [Section 11.9]. In addition to the foregoing, the Borrowers hereby grant to the Administrative Agent, for the benefit of itself, the Issuing [[Organization A:Organization]] and the Revolving Loan Lenders, a properly perfected security interest in and lien on the Letter of Credit Collateral Account, any cash or other funds, notes, certificates of deposit and other instruments that may hereafter be on deposit in the Letter of Credit Collateral Account, any certificates or instruments from time to time evidencing or representing the Letter of Credit Collateral Account, all interest, dividends and other property distributed in respect of or in exchange for the foregoing, and the proceeds thereof (the “Letter of Credit Collateral”), all to secure the payment and performance of the Obligations as set forth below. The Borrowers agree that they will not # sell or otherwise dispose of any interest in the Letter of Credit Collateral or # create or permit to exist any lien, security interest or other charge or encumbrance upon or with respect to any of the

Transfer of Letter of Credit. The Letter of Credit shall provide that Landlord, its successors and assigns, may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) all or any portion of its interest in and to the Letter of Credit to another party, person or entity. In the event of a transfer of Landlord’s interest in the Building, Landlord shall transfer the Letter of Credit, in whole or in part, to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor arising after such transfer, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole or any portion of said Letter of Credit to a new landlord. In connection with any such transfer of the Letter of Credit by Landlord, Tenant shall, at Tenant’s sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer, and Tenant shall be responsible for paying the Bank’s transfer and processing fees in connection therewith.

Application of Letter of Credit. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the Letter of Credit upon the occurrence of any breach or default on the part of Tenant under this Lease. If Tenant shall breach any provision of this Lease or otherwise be in default hereunder, in each case beyond applicable notice and cure periods, Landlord may, but without obligation to do so, and without notice to Tenant, draw upon the Letter of Credit, in part or in whole, to cure any breach or default of Tenant and/or to compensate Landlord for any and all damages of any kind or nature sustained or that Landlord reasonably estimates that it will sustain resulting from Tenant’s breach or default, including, but not limited to, all damages or rent due upon termination of this Lease pursuant to Section 1951.2 of the California Civil Code. The use, application or retention of the Letter of Credit, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any Applicable Laws, it being intended that Landlord shall not first be required to proceed against the Letter of Credit, and the use, application or retention of the Letter of Credit shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the Letter of Credit, either prior to or following a “draw” by Landlord of any portion of the Letter of Credit, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw upon the Letter of Credit. No condition or term of this Lease shall be deemed to render the Letter of Credit conditional to justify the issuer of the Letter of Credit in failing to honor a drawing upon such Letter of Credit in a timely manner. Tenant agrees and acknowledges that # the Letter of Credit constitutes a separate and independent contract between Landlord and the Bank, # Tenant is not a third party beneficiary of such contract, and # in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the Letter of Credit and/or the proceeds thereof by application of Section 502(b)(6) of the U.S. Bankruptcy Code or otherwise.

Payment of Letter of Credit Obligations. The Borrowers agree to reimburse the Letter of Credit Issuer for any draw under any Letter of Credit promptly upon demand, and to pay the issuer of the Letter of Credit (or the Agent, for the account of such issuer) the amount of all other obligations and other amounts payable to such issuer under or in connection with any Letter of Credit immediately when due, irrespective of any claim, setoff, defense or other right which the Borrowers may have at any time against such issuer or any other Person.

Supporting Letter of Credit; Cash Collateral. If, notwithstanding the provisions of this [Section 2.18] and any other provision of this Agreement, any Letter of Credit is outstanding upon the termination of this Agreement, then upon such termination the Borrowers shall deposit with the Agent, for the ratable benefit of the Agent and the Lenders, with respect to each Letter of Credit then outstanding, as the Majority Lenders, in their discretion, shall specify, either # a standby letter of credit (a “Supporting Letter of Credit”) in form and substance satisfactory to the Agent, issued by an issuer satisfactory to the Agent in an amount equal to the greatest amount for which such Letter of Credit may be drawn plus any fees and expenses associated with such Letter of Credit, under which Supporting Letter of Credit the Agent is entitled to draw amounts necessary to reimburse the Agent and the Lenders for payments made by the Agent and the Lenders under such Letter of Credit or under any credit support or enhancement provided through the Agent with respect thereto and any fees and expenses associated with such Letter of Credit or credit support, or # cash in amounts necessary to reimburse the Agent and the Lenders for payments made by the Agent or the Lenders under such Letter of Credit or under any credit support or enhancement provided through the Agent and any fees and expenses associated with such Letter of Credit or credit support. Such Supporting Letter of Credit or deposit of cash shall be held by the Agent, for the ratable benefit of the Agent and the Lenders, as security for, and to provide for the payment of, the aggregate undrawn amount of such Letters of Credit or such credit support remaining outstanding. At Agent's or Letter of Credit Issuer's request, Borrowers shall cash collateralize in a manner satisfactory to Agent the Fronting Exposure of any Defaulting Lender.

No Defaulting Lender shall be entitled to receive any fee described in Section 5.1 for any period during which that Lender is a Defaulting Lender (and Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

Conflict with Letter of Credit Application. In the event of any conflict between the terms of this Agreement and the terms of any Letter of Credit Application, the terms hereof shall control.
