as may be requested by the Borrower and approved by such L/C Issuer, such Letter of Credit to be used solely for the purposes described in Section 4.11. Each Letter of Credit shall by its terms be stated to expire on a date (its “Stated Expiry Date”) no later than the earlier of (i) one year from the date of issuance and (ii) five (5) Business Days prior to the Maturity Date; provided that (x) a Letter of Credit may, if requested by the Borrower, provide on terms acceptable to the Administrative Agent and each applicable L/C Issuer, for automatic renewal for successive periods of one year or less (but not beyond five (5) Business Days prior to the Maturity Date unless the Borrower agrees, pursuant to arrangements reasonably satisfactory to the relevant L/C Issuer entered into on or prior to the Maturity Date, to cash collateralize or backstop such Letter of Credit as of the Maturity Date), unless the Administrative Agent or such L/C Issuer shall have delivered to the beneficiary of such Letter of Credit a notice of non-renewal at least seven (7) Business Days prior to the Stated Expiry Date of such Letter of Credit and (y) to the extent acceptable to the Administrative Agent, any L/C Issuer, if requested by the Borrower, may agree to issue a Letter of Credit on terms acceptable to the Administrative Agent and each applicable L/C Issuer with a Stated Expiry Date beyond the date set forth in clause (i) in its sole discretion (but not beyond the date that is five (5) Business Days prior to the Maturity Date unless the Borrower agrees, pursuant to arrangements reasonably satisfactory to the relevant L/C Issuer entered into on or prior to the Maturity Date, to cash collateralize or backstop such Letter of Credit as of the Maturity Date). The relevant L/C Issuer will make available to the beneficiary thereof the original of each Letter of Credit which it issues hereunder. Unless notified in writing by the Administrative Agent or the Required Lenders before it issues a Letter of Credit that a Default or Event of Default exists or that the conditions precedent for issuing the same have not been established, the relevant L/C Issuer may issue the requested Letter of Credit in accordance with such L/C Issuer’s customary practices.
