               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 year ending
December 31, 1999.

        (b) The Registrant's Quarterly Report on Form 10-Q for the quarter
ending March 31, 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herein shall be deemed to be modified or superseded to the extent that a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 Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        (a) Section 145 of the Delaware General Corporation Law authorizes a
court to award a corporation's Board of Directors the power to indemnify
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. The
Registrant's Second Restated Certificate of Incorporation, as amended, and the
Registrant's Bylaws provide for indemnification of its directors, officers,
employees and other agents to the maximum extent permitted by Delaware Law. In
addition, the Registrant has entered into Indemnification Agreements with its
officers and directors.

        (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.

               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 year ending
December 31, 1999.

        (b) The Registrant's Quarterly Report on Form 10-Q for the quarter
ending March 31, 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

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

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        (a) Section 145 of the Delaware General Corporation Law authorizes a
court to award a corporation's Board of Directors the power to indemnify
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. The
Registrant's Second Restated Certificate of Incorporation, as amended, and the
Registrant's Bylaws provide for indemnification of its directors, officers,
employees and other agents to the maximum extent permitted by Delaware Law. In
addition, the Registrant has entered into Indemnification Agreements with its
officers and directors.

        (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.
