        INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

        The following documents filed by Saba Software, Inc. (the "Registrant")
with the Securities and Exchange Commission (the "Commission") are incorporated
by reference herein:

              1. The Registrant's Prospectus filed pursuant to Rule 424(b) of
the Securities Act and included in the Registration Statement on Form S-1 (the

ITEM 4. DESCRIPTION OF SECURITIES.

        Not Applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        Not Applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Under Section 145 of the General Corporate Law of the State of Delaware,
the Registrant has broad powers to indemnify its directors and officers against
liabilities they may incur in such capacities, including liabilities under the
Securities Act. The Registrant's Amended and Restated Bylaws also provide for
mandatory indemnification of its directors and executive officers, and
permissive indemnification of its employees and agents, to the fullest extent
permissible under Delaware law.

        The Registrant's Amended and Restated Certificate of Incorporation
provides that the liability of its directors for monetary damages shall be
eliminated to the fullest extent permissible under Delaware law. Pursuant to
Delaware law, this includes elimination of liability for monetary damages for
breach of the directors' fiduciary duty of care to the Registrant and its
stockholders. These provisions do not eliminate the directors' duty of care 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 any transaction from which the director derived an improper personal
benefit, 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 laws, such as the federal
securities laws or state or federal environmental laws.

        The Registrant has entered into agreements with its directors and its
executive officers that require the Registrant to indemnify such persons against
expenses, judgments, fines, settlements and other amounts actually and
reasonably incurred (including expenses of a derivative action) in connection
with any proceeding, whether actual or threatened, to which any such person
maybe made a party by reason of the fact that such person is or was a director
or officer of the Registrant or any of its affiliated enterprises, provided such
person acted in good faith and in a manner such person reasonably believed to be
in or not opposed to the best interests of the Registrant and, with respect to
any criminal proceeding, had no reasonable cause to believe such person's
conduct was unlawful. The indemnification agreements also set forth certain
procedures that will apply in the event of a claim for indemnification
thereunder.

        The Registrant has obtained a policy of directors' and officers'
liability insurance that insures its directors and officers against the cost of
defense, settlement or payment of a judgment under certain circumstances.

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;

                       (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;



                                       4
<PAGE>   5

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

             provided, however, that paragraphs (1)(i) and (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 Section 15(d) of the Exchange Act
        that are incorporated by reference in this 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 bring 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 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 this 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 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 the
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 filed by Saba Software, Inc. (the "Registrant")
with the Securities and Exchange Commission (the "Commission") are incorporated

              1. The Registrant's Prospectus filed pursuant to Rule 424(b) of

ITEM 4. DESCRIPTION OF SECURITIES.

        Not Applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        Not Applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Under Section 145 of the General Corporate Law of the State of Delaware,
the Registrant has broad powers to indemnify its directors and officers against
liabilities they may incur in such capacities, including liabilities under the
Securities Act. The Registrant's Amended and Restated Bylaws also provide for
mandatory indemnification of its directors and executive officers, and
permissive indemnification of its employees and agents, to the fullest extent
permissible under Delaware law.

        The Registrant's Amended and Restated Certificate of Incorporation
provides that the liability of its directors for monetary damages shall be
eliminated to the fullest extent permissible under Delaware law. Pursuant to
Delaware law, this includes elimination of liability for monetary damages for
breach of the directors' fiduciary duty of care to the Registrant and its
stockholders. These provisions do not eliminate the directors' duty of care 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 any transaction from which the director derived an improper personal
benefit, 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 laws, such as the federal
securities laws or state or federal environmental laws.

        The Registrant has entered into agreements with its directors and its
executive officers that require the Registrant to indemnify such persons against
expenses, judgments, fines, settlements and other amounts actually and
reasonably incurred (including expenses of a derivative action) in connection
with any proceeding, whether actual or threatened, to which any such person
maybe made a party by reason of the fact that such person is or was a director
or officer of the Registrant or any of its affiliated enterprises, provided such
person acted in good faith and in a manner such person reasonably believed to be
in or not opposed to the best interests of the Registrant and, with respect to
any criminal proceeding, had no reasonable cause to believe such person's
conduct was unlawful. The indemnification agreements also set forth certain
procedures that will apply in the event of a claim for indemnification
thereunder.

        The Registrant has obtained a policy of directors' and officers'
liability insurance that insures its directors and officers against the cost of
defense, settlement or payment of a judgment under certain circumstances.

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;

                       (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;

                                       4
5

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

             provided, however, that paragraphs (1)(i) and (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 Section 15(d) of the Exchange Act
        that are incorporated by reference in this 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 bring 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 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 this 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 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 the
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.
