(a)    For so long as Borrower is Letter of Credit Facility Eligible, upon Borrower's request, Bank may, in its good faith business discretion, issue or have issued Letters of Credit denominated in Dollars or a Foreign Currency for Borrower's account. The aggregate Dollar Equivalent amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letters of Credit Reserve) may not exceed the amounts set forth in Section 2.1.1(b) above. Any such aggregate amounts utilized hereunder shall reduce the amount otherwise available for Credit Extensions hereunder. If, on the Maturity Date, and immediately when Borrower is no longer Letter of Credit Facility Eligible, there are any outstanding Letters of Credit, then on such date Borrower shall provide to Bank cash collateral in an amount equal to one hundred five percent (105.0%) of the Dollar Equivalent amount of all such Letters of Credit plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to such Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank's standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request. Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guaranteed by Bank and opened for Borrower's account or by Bank's interpretations of any Letters of Credit issued by Bank for Borrower's account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower's instructions or those contained in the Letters of Credit or any modifications, amendments, or supplements thereto, except for errors or mistakes directly resulting from Bank's gross negligence or willful misconduct.

(b)    The obligation of Borrower to immediately reimburse Bank for drawings made under Letters of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, such Letters of Credit, and the Letter of Credit Application.

(c)    Borrower may request that Bank issue a Letter of Credit payable in a Foreign Currency. If a demand for payment is made under any such Letters of Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent of the amount thereof

(plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges) in Dollars at the then-prevailing rate of exchange in San Francisco, California, for sales of the Foreign Currency for transfer to the country issuing such Foreign Currency.

(d)    To guard against fluctuations in currency exchange rates, upon the issuance of any Letters of Credit payable in a Foreign Currency, Bank shall create a reserve (the “Letter of Credit Reserve”) in an amount equal to ten percent (10.0%) of the Dollar Equivalent amount of such Letters of Credit. The amount of the Letter of Credit Reserve may be adjusted by Bank from time to time to account for fluctuations in the exchange rate. While Borrower is Letter of Credit Facility Eligible, the availability of funds under either Section 2.1.1 of this Agreement or Section 2.1.1 of the Exim Agreement (as contemplated by Section 2.1.1(b) above) shall be reduced by the amount of such Letter of Credit Reserve for as long as such Letters of Credit remain outstanding.

(e)    Borrower shall pay Bank's customary fees and expenses for the issuance or renewal of Letters of Credit, upon the issuance of such Letter of Credit, each anniversary of the issuance during the term of such Letter of Credit, and upon the renewal of such Letter of Credit by Bank.”
