RE: REGISTRATION STATEMENT ON FORM S-8
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 June 20, 2000
(the "Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 641,801 shares of your Common Stock
under the 1998 Employee Stock Purchase Plan, as amended. Such shares of
Common Stock are referred to herein as the "Shares", and such plan is
referred to herein as the "Plan". 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, when issued and sold in the manner described
in the Plan and pursuant to the agreements which accompany each grant under
the Plan, the Shares will be legally and validly issued, fully-paid and
non-assessable.
We consent to the use of this opinion as an exhibit to the
Registration Statement, and further consent to the use of our name wherever
appearing in the Registration Statement and any amendments thereto.
Very truly yours,
WILSON SONSINI GOODRICH & ROSATI
