ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         The validity of the securities of the Registrant being registered
hereby has been passed upon by Lawrence N. Fisher, Senior Vice President - Law
and Secretary of the Registrant. Mr. Fisher is an executive officer of the
Registrant and holds both restricted and unrestricted shares of the Registrant's
common stock. Mr. Fisher also is eligible to participate in the Plan.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant is a Delaware corporation. Article Nineteen of the
Registrant's Restated Certificate of Incorporation provides that the officers
and directors of the Registrant shall be indemnified and held harmless by the
Registrant to the fullest extent authorized by the Delaware General Corporation
Law, as amended from time to time (the "GCL"). Section 145 of the GCL provides
that a Delaware corporation has the power to indemnify officers and directors in
certain circumstances.

         Subsection (a) of Section 145 of the GCL empowers a corporation to
indemnify any director or officer, or former director or officer, who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action in the right of the corporation), against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred in connection with such action, suit
or proceeding provided such director or officer acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, provided
that such director or officer has no reasonable cause to believe his conduct was
unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
director or officer, or former director or officer, who was or is a party or is
threatened to be made a party to

                                    3
<PAGE>   4

any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above against expenses
(including attorneys' fees) actually and reasonably incurred in connection with
the defense or settlement of such action or suit; provided that such director or
officer acted in good faith and in a manner reasonably believed to be in or not
opposed to the best interests of the corporation. However, no indemnification
may be made in respect of any obligation, issue or matter as to which such
director or officer has been adjudged to be liable to the corporation unless and
only to the extent that the Court of Chancery or the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability, but in view of all the circumstances of the case, the
director or officer is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

         Section 145 further provides that (i) to the extent that a director or
officer has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
or in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith. Article Nineteen of the Registrant's Restated
Certificate of Incorporation provides that the indemnification provided for
thereunder shall be a contract right which shall include the right to be paid
expenses incurred in defending any proceeding in advance of its final
disposition subject to any undertakings required under the GCL. Subsection (e)
of Section 145 requires an undertaking to repay any such amount advanced if the
director or officer receiving such amount is ultimately determined not to be
entitled to indemnification.

         Article Nineteen limits indemnification of any officer or director with
respect to actions initiated by such person to those actions where such
indemnification is approved by the Registrant's Board of Directors.

         Indemnification provided for by Section 145 and Article Nineteen is not
to be deemed exclusive of any other rights to which the indemnified party may be
entitled. Both Section 145 and Article Nineteen permit the Registrant to
maintain insurance on behalf of a director or officer against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the Registrant would have the power to
indemnify him against such liabilities under Section 145.

         Article Nineteen provides that any director or officer claiming rights
to indemnification thereunder may bring suit if such indemnification is not paid
within thirty days. Article Nineteen further provides that the Registrant bears
the burden of proving that the claimant has not met the standards of conduct
required for indemnification under the GCL if the Registrant elects to defend
any such action.

                                       4
<PAGE>   5

         Article Eighteen of the Registrant's Restated Certificate of
Incorporation provides that, to the fullest extent permitted under the GCL, a
director of the Registrant shall not be personally liable to the Registrant or
its stockholders for monetary damages for breach of fiduciary duty as a
director.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8. EXHIBITS.

     4.1    Restated Certificate of Incorporation of the Registrant, as in
            effect as of March 18, 1987 (filed as Exhibit 4.1 to the

     5      Opinion of Lawrence N. Fisher as to legality of the securities

ITEM 9. UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

                  (1)   To file, during the 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;

                  (ii)  to reflect in the prospectus any facts or events arising
                        after the effective

                                    5
<PAGE>   6

                        date of this 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 clauses (i) and (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 Section 13 or
                   Section 15(d) of the Securities Exchange Act of 1934 that are
                   incorporated by reference in this Registration Statement;

                   (2) That for the purpose of determining liability under the
          Securities Act of 1933, 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;

                   (4) That, for the purposes of determining any liability under
          the Securities Act of 1933, each filing of the Registrant's annual
          report pursuant to Section 13(a) of the Securities Exchange Act of
          1934 (and, where applicable, each filing of an employee benefit plan's
          annual report pursuant to Section 15(d) of the Securities Exchange Act
          of 1934) 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; and

                   (5) Insofar as indemnification for liabilities arising under
          the Securities Act of 1933 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 Securities Act of 1933
          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 of 1933 and will be governed by the final adjudication
          of such issue.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         The validity of the securities of the Registrant being registered
hereby has been passed upon by Lawrence N. Fisher, Senior Vice President - Law
and Secretary of the Registrant. Mr. Fisher is an executive officer of the
Registrant and holds both restricted and unrestricted shares of the Registrant's
common stock. Mr. Fisher also is eligible to participate in the Plan.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant is a Delaware corporation. Article Nineteen of the
Registrant's Restated Certificate of Incorporation provides that the officers
and directors of the Registrant shall be indemnified and held harmless by the
Registrant to the fullest extent authorized by the Delaware General Corporation
Law, as amended from time to time (the "GCL"). Section 145 of the GCL provides
that a Delaware corporation has the power to indemnify officers and directors in
certain circumstances.

         Subsection (a) of Section 145 of the GCL empowers a corporation to
indemnify any director or officer, or former director or officer, who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action in the right of the corporation), against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred in connection with such action, suit
or proceeding provided such director or officer acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, provided
that such director or officer has no reasonable cause to believe his conduct was
unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
director or officer, or former director or officer, who was or is a party or is
threatened to be made a party to

                                    3
4

any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above against expenses
(including attorneys' fees) actually and reasonably incurred in connection with
the defense or settlement of such action or suit; provided that such director or
officer acted in good faith and in a manner reasonably believed to be in or not
opposed to the best interests of the corporation. However, no indemnification
may be made in respect of any obligation, issue or matter as to which such
director or officer has been adjudged to be liable to the corporation unless and
only to the extent that the Court of Chancery or the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability, but in view of all the circumstances of the case, the
director or officer is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

         Section 145 further provides that (i) to the extent that a director or
officer has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
or in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith. Article Nineteen of the Registrant's Restated
Certificate of Incorporation provides that the indemnification provided for
thereunder shall be a contract right which shall include the right to be paid
expenses incurred in defending any proceeding in advance of its final
disposition subject to any undertakings required under the GCL. Subsection (e)
of Section 145 requires an undertaking to repay any such amount advanced if the
director or officer receiving such amount is ultimately determined not to be
entitled to indemnification.

         Article Nineteen limits indemnification of any officer or director with
respect to actions initiated by such person to those actions where such
indemnification is approved by the Registrant's Board of Directors.

         Indemnification provided for by Section 145 and Article Nineteen is not
to be deemed exclusive of any other rights to which the indemnified party may be
entitled. Both Section 145 and Article Nineteen permit the Registrant to
maintain insurance on behalf of a director or officer against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the Registrant would have the power to
indemnify him against such liabilities under Section 145.

         Article Nineteen provides that any director or officer claiming rights
to indemnification thereunder may bring suit if such indemnification is not paid
within thirty days. Article Nineteen further provides that the Registrant bears
the burden of proving that the claimant has not met the standards of conduct
required for indemnification under the GCL if the Registrant elects to defend
any such action.

                                       4
5

         Article Eighteen of the Registrant's Restated Certificate of
Incorporation provides that, to the fullest extent permitted under the GCL, a
director of the Registrant shall not be personally liable to the Registrant or
its stockholders for monetary damages for breach of fiduciary duty as a
director.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8. EXHIBITS.

     4.1    Restated Certificate of Incorporation of the Registrant, as in

     23.1   Consent of Independent Auditors

     24     Powers of Attorney

ITEM 9. UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

                  (1)   To file, during the 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;

                  (ii)  to reflect in the prospectus any facts or events arising
                        after the effective

                                    5
6

                        date of this 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 clauses (i) and (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 Section 13 or
                   Section 15(d) of the Securities Exchange Act of 1934 that are
                   incorporated by reference in this Registration Statement;

                   (2) That for the purpose of determining liability under the
          Securities Act of 1933, 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;

                   (4) That, for the purposes of determining any liability under
          the Securities Act of 1933, each filing of the Registrant's annual
          report pursuant to Section 13(a) of the Securities Exchange Act of
          1934 (and, where applicable, each filing of an employee benefit plan's
          annual report pursuant to Section 15(d) of the Securities Exchange Act
          of 1934) 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; and

                   (5) Insofar as indemnification for liabilities arising under
          the Securities Act of 1933 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 Securities Act of 1933
          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 of 1933 and will be governed by the final adjudication
          of such issue.

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the County of Orange, State of California on the 29th day of
