(1)      This Registration Statement covers an aggregate of 1,250,000 shares of
         Common Stock which may be issued pursuant to Registrant's 2000 Employee
         Stock Purchase Plan (the "Plan").

(2)      In accordance with Rule 457(h), the aggregate offering price of
         1,250,000 shares of Common Stock registered hereby which would be
         issued under the Plan is estimated solely for purposes of calculating
         the registration fee, on the basis of the price of securities of the
         same class, as determined in accordance with Rule 457(c), using the
         average of the high and low price reported by NASDAQ National Market
         System for the Common Stock on December 4, 2000, which was $1.078 per
         share.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

        The following documents have been filed by the Registrant with the
Securities and Exchange Commission (the"Commission") and are incorporated herein
by reference:

        (a) The Registrant's Annual Report on Form 10-K for the fiscal year
ended December 31, 1999.

        (b) Registrant's Quarterly Report on Form 10-Q/A for the quarters ended
March 31, 2000 and June 30, 2000 and Form 10-Q for the quarter ended September
30, 2000.

        (c) All other reports filed by the Registrant pursuant to Sections 13(a)
or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), since the end of the fiscal year covered by the annual report referred to
in (a) above.

        (d) The description of the Registrant's Common Stock which is contained
in the Registrant's registration statement on Form 8-A filed on October 15, 1992
pursuant to Section 12 of the Exchange Act, including any amendment or report
filed for the purpose of updating such description.

        All documents subsequently filed by the Registrant pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to the registration statement which indicates that all
of the shares of Common Stock offered have been sold or which deregisters all of
such shares then remaining unsold, shall be deemed to be incorporated by
reference in the registration statement and to be a part hereof from the date of
the filing of such documents; except as to any portion of any future annual or
quarterly report to stockholders or document that is not deemed filed under such
provisions. For the purposes of this registration statement, any statement
contained in a document incorporated or deemed to be incorporated by reference
herein shall be deemed to be modified or superseded to the extent that a
statement contained herein or in any other subsequently filed document which
also is or is deemed to be incorporated by reference herein modifies or
supersedes such statement. Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
registration statement.

Item 4. Description of Securities.

        Not applicable.

Item 5. Interests of Named Experts and Counsel.

        Not applicable.

<PAGE>   3

Item 6. Indemnification of Directors and Officers.

        (a) The Registrant's Certificate of Incorporation limits the liability
of directors to the maximum extent permitted by Delaware law. Delaware law
provides that directors of a company will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except for liability
(i) for any breach of their duty of loyalty to the Registrant or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation of law, (iii) for unlawful payments
or dividends or unlawful stock repurchases or redemptions as provided Section
174 of Delaware General Corporation Law or (iv) for transactions from which the
director derived an improper personal benefit.

        The Registrant's Bylaws provide that the Registrant shall indemnify its
officers and directors and may indemnify its employees and other agents to the
fullest extent provided by Delaware law, including those circumstances where
indemnification would otherwise be discretionary under Delaware law. The
Registrant believes that indemnification under its Bylaws covers at least
negligence on the part of indemnified parties. The Bylaws authorize the use of
indemnification agreements and the Registrant has entered into such agreements
with each of its directors and officers.

        The Registrant maintains directors and officers insurance providing
indemnification for certain of the Registrant's directors, officers, affiliates,
partners or employees for certain liabilities. Delaware Law does not permit a
corporation to eliminate a director's duty of care, and the provisions of the
Registrant's Certificate of Incorporation have no effect on the availability of
equitable remedies such as injunction or rescission, based upon a director's
breach of the duty of care. Insofar as indemnification for liabilities arising
under the Exchange Act may be permitted to foregoing provisions and agreements,
the Registrant has been informed that in the opinion of the staff of the
Commission such indemnification is against public policy as expressed in the
Exchange Act and is therefore unenforceable.

        (b) Pursuant to an Agreement and Plan of Reorganization ("Merger
Agreement") between Registrant and DataWorks Corporation, from and after the
time of the merger, Registrant has agreed to cause the surviving corporation in
the merger to fulfill and honor in all respects the obligations of DataWorks
pursuant to any indemnification agreements between DataWorks and its directors
and officers as of the time of the merger (the "Indemnified Parties") and any
indemnification provisions under DataWorks' Certificate of Incorporation
("DataWorks' Certificate") and DataWorks' Bylaws as in effect on the date of the
Merger Agreement. The Certificate of Incorporation and Bylaws of the surviving
corporation in the merger contain provisions with respect to exculpation and
indemnification that are at least as favorable to the Indemnified Parties as
those contained in DataWorks' Certificate and Bylaws as in effect on the date of
the Merger Agreement, which provisions will not be amended, repealed or
otherwise modified for a period of six years from the time of the merger in any
manner that would adversely affect the rights thereunder of individuals who,
immediately prior to the time of the merger, were directors, officers, employees
or agents of DataWorks, unless such modification is required by law.

        (c) Pursuant to the Merger Agreement, for a period of six years after
the time of the merger, Registrant agreed to cause the surviving corporation in
the merger to use its commercially reasonable efforts to maintain in effect, if
available, director's and officer's liability insurance covering those persons
who were covered by DataWorks' director's and officer's liability insurance
policy on terms comparable to those applicable to the DataWorks director and
officer insurance policy; provided, however that in no event will Registrant or
the surviving corporation in the merger be required to expend in excess of 150%
of the annual premium paid by DataWorks for such coverage (or such coverage as
is available for such 150% of such annual premium).

Item 9. Undertakings.

        (a) The undersigned Registrant hereby undertakes:

            (1) To file, during any period in which offers or sales are being
            made, a post-effective amendment to this registration statement:

                (i) To include any prospectus required by Section 10(a)(3) of
                the Securities Act of 1933 (the "Securities Act");

                (ii) To reflect in the prospectus any facts or events arising
                after the effective date of the registration statement (or the
                most recent post-effective amendment thereof) which,
                individually or in the aggregate, represent a fundamental change
                in the information set forth in the registration statement;

                (iii) To include any material information with respect to the
                plan of distribution not previously disclosed in the
                registration statement or any material change to such
                information in the registration statement;

         Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
         apply if the registration statement is on Form S-3 or Form S-8, and the
         information required to be included in a post-effective amendment by
         those paragraphs is contained in periodic reports filed by the
         Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
         that are incorporated by reference in the registration statement.

             (2) That, for the purpose of determining any liability under the
             Securities Act, each such post-effective amendment shall be deemed
             to be a new registration statement relating to the securities
             offered therein, and the offering of such securities at that time
             shall be deemed to be the initial bona fide offering thereof.

             (3) To remove from registration by means of a post-effective
             amendment any of the securities being registered which remain
             unsold at the termination of the offering.

         (b) The undersigned Registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act, each filing of the
         Registrant's annual report pursuant to Section 13(a) or Section 15(d)
         of the Exchange Act (and, where applicable, each filing of an employee
         benefit plan's annual report pursuant to Section 15(d) of the Exchange
         Act) that is incorporated by reference in the registration statement
         shall be deemed to be a new registration statement relating to the
         securities offered therein, and the offering of such securities at that
         time shall be deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
         Securities Act may be permitted to directors, officers and controlling
         persons of the Registrant pursuant to the foregoing provisions, or
         otherwise, the Registrant has been advised that in the opinion of the
         Securities and Exchange Commission such indemnification is against
         public policy as expressed in the Act and is, therefore, unenforceable.
         In the event that a claim for indemnification against such liabilities
         (other than the payment by the Registrant of expenses incurred or paid
         by a director, officer or controlling person of the Registrant in the
         successful defense of any action, suit or proceeding) is asserted by
         such director, officer or controlling person in connection with the
         securities being registered, the Registrant will, unless in the opinion
         of its counsel the matter has been settled by controlling precedent,
         submit to a court of appropriate jurisdiction the question whether such
         indemnification by it is against public policy as expressed in the Act
         and will be governed by the final adjudication of such issue.

         Stock Purchase Plan (the "Plan").

         1,250,000 shares of Common Stock registered hereby which would be
         issued under the Plan is estimated solely for purposes of calculating
         the registration fee, on the basis of the price of securities of the
         same class, as determined in accordance with Rule 457(c), using the
         average of the high and low price reported by NASDAQ National Market
         System for the Common Stock on December 4, 2000, which was $1.078 per
         share.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

        The following documents have been filed by the Registrant with the
Securities and Exchange Commission (the"Commission") and are incorporated herein
by reference:

        (a) The Registrant's Annual Report on Form 10-K for the fiscal year
ended December 31, 1999.

        (b) Registrant's Quarterly Report on Form 10-Q/A for the quarters ended
March 31, 2000 and June 30, 2000 and Form 10-Q for the quarter ended September
30, 2000.

        (c) All other reports filed by the Registrant pursuant to Sections 13(a)
or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), since the end of the fiscal year covered by the annual report referred to
in (a) above.

        (d) The description of the Registrant's Common Stock which is contained
in the Registrant's registration statement on Form 8-A filed on October 15, 1992
pursuant to Section 12 of the Exchange Act, including any amendment or report
filed for the purpose of updating such description.

        All documents subsequently filed by the Registrant pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to the registration statement which indicates that all
of the shares of Common Stock offered have been sold or which deregisters all of
such shares then remaining unsold, shall be deemed to be incorporated by
reference in the registration statement and to be a part hereof from the date of
the filing of such documents; except as to any portion of any future annual or
quarterly report to stockholders or document that is not deemed filed under such
provisions. For the purposes of this registration statement, any statement
contained in a document incorporated or deemed to be incorporated by reference
herein shall be deemed to be modified or superseded to the extent that a
statement contained herein or in any other subsequently filed document which
also is or is deemed to be incorporated by reference herein modifies or
supersedes such statement. Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
registration statement.

Item 4. Description of Securities.

        Not applicable.

Item 5. Interests of Named Experts and Counsel.

        Not applicable.

Item 6. Indemnification of Directors and Officers.

        (a) The Registrant's Certificate of Incorporation limits the liability
of directors to the maximum extent permitted by Delaware law. Delaware law
provides that directors of a company will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except for liability
(i) for any breach of their duty of loyalty to the Registrant or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation of law, (iii) for unlawful payments
or dividends or unlawful stock repurchases or redemptions as provided Section
174 of Delaware General Corporation Law or (iv) for transactions from which the
director derived an improper personal benefit.

        The Registrant's Bylaws provide that the Registrant shall indemnify its
officers and directors and may indemnify its employees and other agents to the
fullest extent provided by Delaware law, including those circumstances where
indemnification would otherwise be discretionary under Delaware law. The
Registrant believes that indemnification under its Bylaws covers at least
negligence on the part of indemnified parties. The Bylaws authorize the use of
indemnification agreements and the Registrant has entered into such agreements
with each of its directors and officers.

        The Registrant maintains directors and officers insurance providing
indemnification for certain of the Registrant's directors, officers, affiliates,
partners or employees for certain liabilities. Delaware Law does not permit a
corporation to eliminate a director's duty of care, and the provisions of the
Registrant's Certificate of Incorporation have no effect on the availability of
equitable remedies such as injunction or rescission, based upon a director's
breach of the duty of care. Insofar as indemnification for liabilities arising
under the Exchange Act may be permitted to foregoing provisions and agreements,
the Registrant has been informed that in the opinion of the staff of the
Commission such indemnification is against public policy as expressed in the
Exchange Act and is therefore unenforceable.

        (b) Pursuant to an Agreement and Plan of Reorganization ("Merger
Agreement") between Registrant and DataWorks Corporation, from and after the
time of the merger, Registrant has agreed to cause the surviving corporation in
the merger to fulfill and honor in all respects the obligations of DataWorks
pursuant to any indemnification agreements between DataWorks and its directors
and officers as of the time of the merger (the "Indemnified Parties") and any
indemnification provisions under DataWorks' Certificate of Incorporation
("DataWorks' Certificate") and DataWorks' Bylaws as in effect on the date of the
Merger Agreement. The Certificate of Incorporation and Bylaws of the surviving
corporation in the merger contain provisions with respect to exculpation and
indemnification that are at least as favorable to the Indemnified Parties as
those contained in DataWorks' Certificate and Bylaws as in effect on the date of
the Merger Agreement, which provisions will not be amended, repealed or
otherwise modified for a period of six years from the time of the merger in any
manner that would adversely affect the rights thereunder of individuals who,
immediately prior to the time of the merger, were directors, officers, employees
or agents of DataWorks, unless such modification is required by law.

        (c) Pursuant to the Merger Agreement, for a period of six years after
the time of the merger, Registrant agreed to cause the surviving corporation in
the merger to use its commercially reasonable efforts to maintain in effect, if
available, director's and officer's liability insurance covering those persons
who were covered by DataWorks' director's and officer's liability insurance
policy on terms comparable to those applicable to the DataWorks director and
officer insurance policy; provided, however that in no event will Registrant or
the surviving corporation in the merger be required to expend in excess of 150%
of the annual premium paid by DataWorks for such coverage (or such coverage as
is available for such 150% of such annual premium).

Item 9. Undertakings.

        (a) The undersigned Registrant hereby undertakes:

            (1) To file, during any period in which offers or sales are being
            made, a post-effective amendment to this registration statement:

                (i) To include any prospectus required by Section 10(a)(3) of
                the Securities Act of 1933 (the "Securities Act");

                (ii) To reflect in the prospectus any facts or events arising
                after the effective date of the registration statement (or the
                most recent post-effective amendment thereof) which,
                individually or in the aggregate, represent a fundamental change
                in the information set forth in the registration statement;

                (iii) To include any material information with respect to the
                plan of distribution not previously disclosed in the
                registration statement or any material change to such
                information in the registration statement;

         Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
         apply if the registration statement is on Form S-3 or Form S-8, and the
         information required to be included in a post-effective amendment by
         those paragraphs is contained in periodic reports filed by the
         Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
         that are incorporated by reference in the registration statement.

             (2) That, for the purpose of determining any liability under the
             Securities Act, each such post-effective amendment shall be deemed
             to be a new registration statement relating to the securities
             offered therein, and the offering of such securities at that time
             shall be deemed to be the initial bona fide offering thereof.

             (3) To remove from registration by means of a post-effective
             amendment any of the securities being registered which remain
             unsold at the termination of the offering.

         (b) The undersigned Registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act, each filing of the
         Registrant's annual report pursuant to Section 13(a) or Section 15(d)
         of the Exchange Act (and, where applicable, each filing of an employee
         benefit plan's annual report pursuant to Section 15(d) of the Exchange
         Act) that is incorporated by reference in the registration statement
         shall be deemed to be a new registration statement relating to the
         securities offered therein, and the offering of such securities at that
         time shall be deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
         Securities Act may be permitted to directors, officers and controlling
         persons of the Registrant pursuant to the foregoing provisions, or
         otherwise, the Registrant has been advised that in the opinion of the
         Securities and Exchange Commission such indemnification is against
         public policy as expressed in the Act and is, therefore, unenforceable.
         In the event that a claim for indemnification against such liabilities
         (other than the payment by the Registrant of expenses incurred or paid
         by a director, officer or controlling person of the Registrant in the
         successful defense of any action, suit or proceeding) is asserted by
         such director, officer or controlling person in connection with the
         securities being registered, the Registrant will, unless in the opinion
         of its counsel the matter has been settled by controlling precedent,
         submit to a court of appropriate jurisdiction the question whether such
         indemnification by it is against public policy as expressed in the Act
         and will be governed by the final adjudication of such issue.
