               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE

     The following documents, which have been filed by Hyperion Solutions
Corporation (formerly Arbor Software Corporation) (the "Registrant") with the
Securities and Exchange Commission (the "Commission"), are hereby incorporated
by reference in this Registration Statement:

     (a)  Registrant's Annual Report on Form 10-K for the fiscal year ended June
          30, 2000; and

     (b)  Registrant's Registration Statement No. 0-97098 on Form 8-A filed with
          the Commission on September 19, 1995 pursuant to Section 12 of the
          Securities Exchange Act of 1934, as amended (the "1934 Act"), as
          amended on Form 8-A/A, dated November 3, 1995, in which there is
          described the terms, rights and provisions applicable to the
          Registrant's outstanding Common Stock.

     All documents subsequently filed pursuant to Section 13(a), 13(c), 14 or
15(d) of the Exchange Act and prior to the termination of the offering of the
securities offered hereby shall be deemed to be incorporated by reference into
this registration statement and to be a part hereof from the respective dates of
filing of such documents. Any statement contained in a document incorporated or
deemed to be incorporated by reference herein shall be deemed to be modified or
superseded for purposes of this registration statement to the extent that a
statement contained herein, or in any other subsequently filed document that
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 Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this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

     Section 145 of the Delaware General Corporation Law, as amended, authorizes
a court to award or a corporation's Board of Directors to grant indemnification
to 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 of 1933 as
amended (the "1933 Act.") The Registrant's Bylaws provide for mandatory
indemnification of its directors and officers and permissible indemnification of
employees and other agents to the maximum extent permitted by the Delaware
General Corporation Law. The Registrant's Certificate of Incorporation provides
that, pursuant to Delaware law, its directors shall not be liable for monetary
damages for breach of their fiduciary duty as directors to the Registrant and
its stockholders. This provision in the Certificate of Incorporation does not
eliminate the fiduciary duty of the directors, and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware law. In addition, each
director will continue to be subject to liability for breach of the director's
duty of loyalty to the Registrant for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law, for actions
leading to improper personal benefit to the director and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. The Registrant has entered into
Indemnification Agreements with its officers and directors. The


                                      II-1

<PAGE>   3

Indemnification Agreements provide the Registrant's officers and directors with
further indemnification to the maximum extent permitted by the Delaware General
Corporation Law.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

     Not applicable.

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, as amended (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
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 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.


                                      II-2

<PAGE>   4

          (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 Stock Option Agreement and 1999 Stock Option Plan offering.

     B.   The undersigned registrant hereby undertakes that, for purposes of
determining liability under the Securities Act, each filing of the registrant's
annual report pursuant to Section 13(a) or 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 provisions described in Item 6, 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 Securities 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
Securities 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, which have been filed by Hyperion Solutions
Corporation (formerly Arbor Software Corporation) (the "Registrant") with the
Securities and Exchange Commission (the "Commission"), are hereby incorporated
by reference in this Registration Statement:

     (a)  Registrant's Annual Report on Form 10-K for the fiscal year ended June
          30, 2000; and

     (b)  Registrant's Registration Statement No. 0-97098 on Form 8-A filed with
          the Commission on September 19, 1995 pursuant to Section 12 of the
          Securities Exchange Act of 1934, as amended (the "1934 Act"), as
          amended on Form 8-A/A, dated November 3, 1995, in which there is
          described the terms, rights and provisions applicable to the
          Registrant's outstanding Common Stock.

     All documents subsequently filed pursuant to Section 13(a), 13(c), 14 or
15(d) of the Exchange Act and prior to the termination of the offering of the
securities offered hereby shall be deemed to be incorporated by reference into
this registration statement and to be a part hereof from the respective dates of
filing of such documents. Any statement contained in a document incorporated or
deemed to be incorporated by reference herein shall be deemed to be modified or
superseded for purposes of this registration statement to the extent that a
statement contained herein, or in any other subsequently filed document that
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 4. DESCRIPTION OF SECURITIES

     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law, as amended, authorizes
a court to award or a corporation's Board of Directors to grant indemnification
to 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 of 1933 as
amended (the "1933 Act.") The Registrant's Bylaws provide for mandatory
indemnification of its directors and officers and permissible indemnification of
employees and other agents to the maximum extent permitted by the Delaware
General Corporation Law. The Registrant's Certificate of Incorporation provides
that, pursuant to Delaware law, its directors shall not be liable for monetary
damages for breach of their fiduciary duty as directors to the Registrant and
its stockholders. This provision in the Certificate of Incorporation does not
eliminate the fiduciary duty of the directors, and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware law. In addition, each
director will continue to be subject to liability for breach of the director's
duty of loyalty to the Registrant for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law, for actions
leading to improper personal benefit to the director and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. The Registrant has entered into
Indemnification Agreements with its officers and directors. The

                                      II-1
3

Indemnification Agreements provide the Registrant's officers and directors with
further indemnification to the maximum extent permitted by the Delaware General
Corporation Law.

     24.1      Power of Attorney (page II-4).

     99.1      Stock Option Agreement dated as of October 11, 1999 between
               Registrant and Jeffrey R. Rodek (Incorporated herein by reference
               is Exhibit 10.2 to Registrant's Quarterly Report on Form 10-Q for
               the quarterly period ended December 31, 1999).

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, as amended (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
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 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.

                                      II-2

          (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 Stock Option Agreement and 1999 Stock Option Plan offering.

     B.   The undersigned registrant hereby undertakes that, for purposes of
determining liability under the Securities Act, each filing of the registrant's
annual report pursuant to Section 13(a) or 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 provisions described in Item 6, 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 Securities 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
Securities Act and will be governed by the final adjudication of such issue.
