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 1,900,000 shares of your Common Stock
under the 1996 Stock Incentive Program, 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
