ABL CREDIT FACILITY

During fiscal 2012, Ciena and certain of its subsidiaries entered into a senior secured asset-based revolving credit facility (the “ABL Credit Facility”). On July 15, 2014, Ciena amended the ABL Credit Facility to, among other things:


•	increase the total committed amount from $150 million to $200 million;


•	extend the maturity date from August 13, 2015 to December 31, 2016, and eliminate the maturity date acceleration to December 15, 2014 in the event that any of Ciena’s 4.00% senior convertible notes due March 15, 2015 are then outstanding;


•	reduce the minimum aggregate amount of unrestricted cash and cash equivalents that Ciena is required to maintain at all times from $200 million to $150 million;


•	reduce the interest rate on borrowings from LIBOR plus an applicable margin ranging from 200 basis points to 250 basis points, to an applicable margin ranging from 150 basis points to 200 basis points, with the actual margin based upon Ciena's utilization of the ABL Credit Facility; and


•	amend the borrowing base to include, among other items, up to $50 million in eligible cash.

Ciena also amended the terms of the existing security and pledge agreements to provide the lenders with second-priority security interests in the Term Loan Priority Collateral, in addition to its existing first-priority security interests in current assets, consisting principally of accounts receivable, inventory, cash, and deposit and securities accounts (the "ABL Priority Collateral"). Except as amended, the remaining terms of the ABL Credit Facility, and related security and pledge agreements, remain in full force and effect.

Ciena principally uses the ABL Credit Facility to support the issuance of letters of credit that arise in the ordinary course of its business and thereby to reduce its use of cash required to collateralize these instruments. As of October 31, 2014, letters of credit totaling $71.4 million were collateralized by the ABL Credit Facility. There were no borrowings outstanding under the ABL Credit Facility as of October 31, 2014.
