     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 May 1, 2001, (the
"Registration Statement") in connection with the registration under the
Securities Act 1933, as amended (the "Act"), of 400,000 shares of your Common
Stock issuable under the 2000 Stock Plan and 50,000 shares issuable under the
2000 Employee Stock Purchase Plan.  Such shares of Common Stock are referred to
herein as the "Shares," and the 2000 Stock Plan and the 2000 Employee Stock
Purchase Plan are referred to herein as the "Plans."  As your legal 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 Plans.

     It is our opinion that, upon completion of the proceedings being taken, or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares pursuant to the Registration Statement and the Plan, including the
proceedings being taken in order to permit such transaction to be carried out in
accordance with applicable state securities laws, the Shares, when issued and
sold in the manner described in the Registration Statement and in accordance
with the resolutions adopted by the Board of Directors of the Company, 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 further consent to the use of our name wherever appearing in the
Registration Statement and any amendments thereto.

                                Very truly yours,

     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 May 1, 2001, (the
"Registration Statement") in connection with the registration under the
Securities Act 1933, as amended (the "Act"), of 400,000 shares of your Common
Stock issuable under the 2000 Stock Plan and 50,000 shares issuable under the
2000 Employee Stock Purchase Plan.  Such shares of Common Stock are referred to
herein as the "Shares," and the 2000 Stock Plan and the 2000 Employee Stock
Purchase Plan are referred to herein as the "Plans."  As your legal 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 Plans.

     It is our opinion that, upon completion of the proceedings being taken, or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares pursuant to the Registration Statement and the Plan, including the
proceedings being taken in order to permit such transaction to be carried out in
accordance with applicable state securities laws, the Shares, when issued and
sold in the manner described in the Registration Statement and in accordance
with the resolutions adopted by the Board of Directors of the Company, 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 further consent to the use of our name wherever appearing in the
Registration Statement and any amendments thereto.

                                Very truly yours,

                                /s/WILSON SONSINI GOODRICH & ROSATI
