ITEM 4. DESCRIPTION OF SECURITIES.

     Not applicable.


<PAGE>   4


ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Registrant's Amended and Restated Articles of Incorporation limit the
liability of the Registrant's directors for monetary damages to the maximum
extent permitted by California law. Such limitation of liability has no effect
on the availability of equitable remedies, such as injunctive relief or
rescission.

     The Registrant's Amended and Restated Bylaws provide that the Registrant
will indemnify its directors and officers and may indemnify its employees and
agents (other than officers and directors) against certain liabilities to the
maximum extent permitted by California law. The Registrant has entered into
indemnification agreements with each of its current directors and officers and
certain of its key employees that provide for indemnification of, and
advancement of expenses to, such persons to the maximum extent permitted by
California law, including by reason of action or inaction occurring in the past
and circumstances in which indemnification and advancement of expenses are
discretionary under California law.

     At the present time, there is no pending litigation or proceeding involving
a director, officer, employee or other agent of the Registrant in which
indemnification would be required or permitted. The Registrant is not aware of
any threatened litigation or proceeding that may result in a claim for such
indemnification.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

     Not applicable.

ITEM 9. UNDERTAKINGS.

     1.   The 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 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.

                                      -3-

<PAGE>   5

          (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.

     2.   The 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 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.

     3.   Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to law, the Registrant's Articles of Incorporation,
Bylaws or indemnification agreements, 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 expenses incurred or paid by a director, officer or
controlling person of the Registrant in a successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, 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 of 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.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Registrant's Amended and Restated Articles of Incorporation limit the
liability of the Registrant's directors for monetary damages to the maximum
extent permitted by California law. Such limitation of liability has no effect
on the availability of equitable remedies, such as injunctive relief or
rescission.

     The Registrant's Amended and Restated Bylaws provide that the Registrant
will indemnify its directors and officers and may indemnify its employees and
agents (other than officers and directors) against certain liabilities to the
maximum extent permitted by California law. The Registrant has entered into
indemnification agreements with each of its current directors and officers and
certain of its key employees that provide for indemnification of, and
advancement of expenses to, such persons to the maximum extent permitted by
California law, including by reason of action or inaction occurring in the past
and circumstances in which indemnification and advancement of expenses are
discretionary under California law.

     At the present time, there is no pending litigation or proceeding involving
a director, officer, employee or other agent of the Registrant in which
indemnification would be required or permitted. The Registrant is not aware of
any threatened litigation or proceeding that may result in a claim for such
indemnification.

ITEM 9. UNDERTAKINGS.

     1.   The 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 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.

                                      -3-
5

          (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.

     2.   The 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 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.

     3.   Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to law, the Registrant's Articles of Incorporation,
Bylaws or indemnification agreements, 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 expenses incurred or paid by a director, officer or
controlling person of the Registrant in a successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, 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 of 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.
