Milpitas, California, November 6, 2006 – JDSU today announced that it has received an unsolicited “mini-tender” offer from TRC Capital Corporation to purchase from JDSU stockholders up to 3 million shares of JDSU common stock, or approximately 1.4% of its total outstanding shares, for $14.00 per share.   The offer price represents an 18.4% discount to JDSU’s closing price of $16.58 on November 3, 2006, and a 3.7% discount to JDSU’s closing price of $14.53 per share on October 31, 2006, the day the offer was made.

JDSU does not endorse or recommend TRC Capital’s “mini-tender” offer, and wishes to inform its stockholders that it is not associated with TRC Capital, the offer or the offer documentation.

JDSU understands that TRC Capital has made numerous “mini-tender” offers for shares of other companies.   “Mini-tender” offers are third-party offers to purchase less than five percent of a company’s shares, thereby avoiding most of the filing, disclosure and procedural requirements of the Securities and Exchange Commission (SEC).

The SEC has issued an investor alert regarding “mini-tender” offers, noting that “some bidders make mini-tender offers at below-market prices, hoping that they will catch investors off guard if the investors do not compare the offer price to the current market price.”  JDSU encourages stockholders to read the SEC’s article on this subject, which is available at http://www.sec.gov/investor/pubs/minitend.htm.

JDSU urges stockholders to obtain current market quotations for their shares, to consult with their own brokers or financial advisors, and to request a copy of the offer from TRC Capital to review, before deciding whether to sell their shares.
