Notes:

On November 7, 2008, Foundry Networks, Inc. and Brocade Communications Systems, Inc. issued the following joint press release announcing the execution of an Amendment No. 1 to the Agreement and Plan of Merger, dated as of November 7, 2008 and the cancellation of Foundry’s special meeting of stockholders scheduled to be held on that date:

Brocade and Foundry Networks Announce Signing of
Amendment to Definitive Agreement for Acquisition of
Foundry by Brocade

Friday November 7, 6:32 pm ET

Foundry to reschedule special meeting of stockholders

SAN JOSE and SANTA CLARA, Calif., Nov. 7 /PRNewswire-FirstCall/ — Brocade® (Nasdaq: BRCD - News ) and Foundry Networks®, Inc. (Nasdaq: FDRY — News ) today announced that they have signed an amendment to the definitive agreement, which provides for the acquisition of the outstanding shares of Foundry Networks by Brocade. Under the revised terms, Foundry stockholders would be entitled to receive $16.50 per share in an all-cash transaction at the closing of the deal, as previously announced by the companies on Oct. 29, 2008. In addition, Foundry stockholders may receive the proceeds of the sale of Foundry’s portfolio of auction rate securities — up to approximately $50 million in the aggregate — calculated on a fully diluted basis based on the treasury stock method, if Foundry is successful in liquidating its portfolio of these securities prior to the close of the acquisition. It is anticipated that such amount, if any, would be distributed shortly before the closing of the acquisition through a dividend to Foundry stockholders.

Brocade expects to finance the acquisition from various financing sources, including cash on hand at both companies and the net proceeds from a $1.1 billion term loan facility which has already been deposited into a restricted Brocade custody account pending the closing of the acquisition of Foundry and other customary release conditions.

“We are excited about this transaction and believe that the combination will provide a number of strategic and financial benefits that we expect will be well-received by the customers of both companies,” said Mike Klayko, CEO of Brocade. “This will help to solidify Brocade’s position as a proven, high-performance networking leader for today’s most demanding, data-intensive organizations.”

The two companies originally entered into an agreement on July 21, 2008. The revised agreement has been approved by the boards of directors of Brocade and Foundry, and the board of directors of Foundry has unanimously recommended that Foundry stockholders vote in favor of the revised transaction. Foundry stockholders must also vote on the revised agreement in a special meeting currently expected to be held in December 2008. Pending Foundry stockholder approval, the companies expect to close the transaction in late December 2008, subject to the satisfaction of customary terms and conditions.

Foundry Special Stockholder Meeting

Foundry also announced today that its special stockholder meeting scheduled for Friday, November 7, 2008 at 4:00 p.m. Pacific Time will be cancelled and rescheduled for a later date. The new date for the special stockholder meeting has not been set by Foundry but is currently expect to be set for December 2008. A notice of the new date for the special meeting of stockholders and revised proxy statement materials regarding the revised transaction will be sent to Foundry stockholders in advance of the rescheduled special stockholder meeting. In addition, Foundry has set a new record date of

November 7, 2008 for the special meeting of stockholders to vote on the adoption of the revised merger agreement.

Additional information related to the revised merger agreement can be found in the Form 8-K that Brocade expects to file shortly.

Cautionary Statement

This press release contains statements that are forward-looking in nature, including statements regarding the anticipated benefits of the acquisition, the timing of future stockholder communication and meetings, conditions remaining to be completed for the expected close of the proposed transaction, the ability of Foundry to sell its auction rate securities, and funding for the acquisition. These statements are based on current expectations on the date of this press release and involve a number of risks and uncertainties. The risks include, but are not limited to, the risk that the transaction under the amended terms and conditions may not close; the possibility that expected synergies and cost savings will not be obtained; the difficulty of integrating the business, operations and employees of the two companies; unanticipated developments in the market for enterprise and service provider networking and data centers and related products and services; and whether a market for auction rate securities exists or will exist prior to the close of the acquisition and at what price such securities could or will be sold. Neither Brocade nor Foundry assume any obligation to update or revise any such forward-looking statements, whether as the result of new developments or otherwise.
