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 the date hereof (the
“Registration Statement”) in connection with the registration under the
Securities Act of 1933, as amended, of an additional 3,174,595 shares of your
Common Stock issuable under your 2001 Employee Stock Purchase Plan and an
additional 216,038 shares of Common Stock issuable under your International
Employee Stock Purchase 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, 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 Plans.
It
is our
opinion that, upon completion of the actions being taken, or contemplated by
us
as your counsel to be taken by you prior to the issuance of the Shares pursuant
to the Registration Statement and the Plans and upon completion of the actions
being taken in order to permit such transactions to be carried out in accordance
with the securities laws of the various states where required, the
Shares, when issued and sold in the manner referred to in the Plans and pursuant
to 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 said Registration Statement
and further consent to the use of our name wherever appearing in said
Registration Statement, and any amendments thereto.
Very
truly yours,
