      RE:   REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

      We have examined the Registration Statement on Form S-8 to be filed by you
with the Securities and Exchange Commission on or about April 22, 2003 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended (the "Act") of 9,000,000 shares of Common
Stock available for issuance under your 2003 Employee Stock Purchase Plan and
12,000,000 shares of Common Stock available for issuance under your 1999 Stock
Plan. Such shares of Common Stock are referred to herein as the "Shares," and
such plans are referred to herein as the "Plans". As your counsel in connection
with this transaction, we have examined the proceedings taken and are familiar
with the proceedings proposed to be taken by you in connection with the issuance
and sale of the Shares pursuant to the Plan.

      It is our opinion that the Shares, when issued and sold in the manner
referred to in the Plans and the agreements which accompany the Plans, will be
legally and validly issued, fully paid and nonassessable.


      We consent to the use of this opinion as an exhibit to the Registration
Statement, and consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendments thereto.


                                          Very truly yours,

                                          WILSON SONSINI GOODRICH & ROSATI
