     Registration Statement on Form S-1
     ----------------------------------

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1 filed by you with
the Securities and Exchange Commission on April 16, 1999 (the "Registration
Statement") in connection with the registration under the Securities Act of
1933, as amended, of a total of 4,600,000 shares of your Common Stock (the
"Shares") to be sold to the underwriters as described in the Registration
Statement for resale to the public, including an over-allotment option to
purchase 600,000 shares granted to the underwriters.  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
sale and issuance of the Shares.

     It is our opinion that upon conclusion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, and upon completion of the proceedings 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
described in the Registration Statement 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, including the Prospectus constituting a part thereof,
and in any amendment thereto.

                                        Sincerely,

                                        VENTURE LAW GROUP
