Explanation of Responses:

1. Pursuant to the Agreement and Plan of Merger by and among the Issuer, Neptune Acquisition Subsidiary, Inc. and Ciena Corporation ("Ciena") dated May 3, 2015, as amended (the "Merger Agreement"), each share of Issuer common stock will be exchanged for $0.63 in cash and 0.19936 shares of Ciena's common stock at the Effective Time (as defined in the Merger Agreement) by virtue of the merger.

2. Of the reported securities, 8,500 shares are represented by restricted stock units. Pursuant to the Issuer's Non-Employee Director Compensation and Expense Reimbursement Program, all of the restricted stock units vested in full upon the effectiveness of the Merger. Each Issuer restricted stock unit that is vested but not yet settled as of the Effective Time will be deemed paid in shares of Issuer common stock immediately prior to the Effective Time, and the holder of such restricted stock unit will be entitled to receive $0.63 in cash and 0.19936 shares of Ciena's common stock with respect to each such share of Issuer common stock otherwise issuable pursuant to such vested (but not yet settled) restricted stock units.

3. These securities are held directly by Mr. Ferris and were issued to Mr. Ferris in connection with his services to the Issuer as a director. Pursuant to an arrangement with Azure Capital Partners VC Administrators II, L. P. ("Azure GP"), Mr. Ferris will assign to Azure Capital Partners, L.P.

Each of the Azure Entities disclaims beneficial ownership in such securities, except to the extent, if any, of their respective pecuniary interest therein.

5. These shares are held directly by ACP II. Each of the Azure Entities disclaims beneficial ownership in such securities, except to the extent, if any, of their respective pecuniary interest therein.
