SANTA CLARA, Calif., Oct. 31 /PRNewswire-FirstCall/ -- Foundry Networks(TM), Inc. (Nasdaq: FDRY) today released additional information related to the agreement in principle announced yesterday, October 29, 2008, to amend the acquisition agreement between the two companies relating to Brocade's proposed acquisition of Foundry.

If a definitive agreement is reached between Foundry and Brocade regarding the new agreement in principle, the stockholder meeting scheduled for Friday, November 7, 2008 at 4:00pm PST will be further delayed and additional information regarding the restructured transaction will be distributed to Foundry's stockholders for their consideration. In that event, it is anticipated that the Foundry stockholder meeting to consider the restructured transaction would be convened in December 2008, with a closing of the transaction in the second half of December 2008.

Under the agreement in principle reached Wednesday, Foundry's stockholders would be entitled to receive $16.50 of cash for each share of Foundry common stock. No fractional shares of Brocade common stock will be issued to Foundry stockholders. In addition, the agreement in principle provides that in certain circumstances, Foundry stockholders could receive the proceeds of the sale of Foundry's portfolio of auction rate securities, up to an amount of $50 million in the aggregate, or up to approximately $0.33 per share of Foundry common stock, if Foundry is able to successfully liquidate its portfolio of these securities prior to the close of the acquisition. There can be no assurance, however, that the securities are marketable or at what price such securities could or will be sold, or that a market for these securities exists or will exist prior to the close of the acquisition. The revised transaction would have an aggregate purchase price of approximately $2.6 billion exclusive of the additional $50 million described above.

Cautionary Statement

This press release contains statements that are forward-looking in nature; including statements regarding the timing of future shareholder communications and meetings, conditions remaining to be completed for the close of the proposed acquisition, the ability of Foundry and Brocade to reach a mutually agreeable amendment to the acquisition agreement to reflect the terms agreed to in the agreement in principle. These statements are based on current expectations on the date of this press release and involve a number of risks and uncertainties.

Certain of these and other risks are set forth in more detail under "Item 1A. Risk Factors" in Foundry's Quarterly Report on Form 10-Q for the quarter ended June 30, 2008.
