RE: REGISTRATION STATEMENT ON FORM SB-2
 
Ladies and Gentlemen:
 
   
    We have examined the Registration Statement on Form SB-2 to be filed by
DeltaPoint, Inc., a California corporation (the "Company"), with the Securities
and Exchange Commission on September 2, 1997, in connection with the
registration under the Securities Act of 1933, as amended, of 3,450,000 shares
of the Company's Common Stock, par value $0.001 per share (the "Shares")
(including an over-allotment option to purchase 450,000 shares). The Shares are
to be sold to the underwriters for resale to the public as described in the
Registration Statement and pursuant to the Underwriting Agreement filed as an
exhibit thereto. As legal counsel to the Company, we have examined the
proceedings proposed to be taken in connection with said sale and issuance of
the Shares.
    
 
    Based upon the foregoing, we are of the opinion that the Shares, when issued
in the manner described in the Registration Statement, will be duly authorized,
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, including the Prospectus constituting a part thereof,
and any amendment thereto.
 
                                          Very truly yours,
                                          WILSON SONSINI GOODRICH & ROSATI
