         Not applicable.


ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         1. Section 145 of the Delaware General Corporation Law ("DGCL").
Section 145 of the DGCL provides that a corporation may indemnify any person who
was or is a party or is threatened to be made a party to




<PAGE>   3

any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that the person is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding if the person 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, had no
reasonable cause to believe the person's conduct was unlawful. The termination
of any action, suit or proceeding by judgment, order, settlement or conviction,
or upon a plea of nolo contendere or its equivalent, shall not, of itself,
create a presumption that the person did not act 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, had
reasonable cause to believe that the person's conduct was unlawful.

         Section 145 also provides that a corporation may indemnify any person
who was or is a party or is threatened to be made a party to 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 the person is or was
a director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred by
the person in connection with the defense or settlement of such action or suit,
if the person acted in good faith and in a manner reasonably believed to be in
or not opposed to the best interests of the corporation, and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have 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,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

         To the extent that a former or present director or officer of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to above, or in defense of any claim, issue
or matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.

         Any such indemnification (unless ordered by a court) shall be made by
the corporation only as authorized in the specific case upon a determination
that the indemnification of the present or former director, officer, employee or
agent is proper in the circumstances because such person has met the applicable
standard of conduct set forth above. Such determination shall be made:

                  (1) by a majority vote of the directors who were not parties
         to such action, suit or proceeding, even though less than a quorum; or

                  (2) by a committee of such directors designated by a majority
         vote of such directors, even though less than a quorum; or

                  (3) if there are no such directors, or, if such directors so
         direct, by independent legal counsel in a written opinion; or

                  (4) by the stockholders.

         Section 145 permits a Delaware business corporation to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against any liability
asserted against such person and incurred by such person in any such capacity



                                      -2-
<PAGE>   4

or arising out of such person's status as such, whether or not the corporation
would have the power to indemnify such person against such liability.

         2. Section 102(b)(7) of the DGCL. Section 102(b)(7) of the DGCL
provides that a corporation may set forth in its Certificate of Incorporation a
provision eliminating or limiting the personal liability of a director to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such provision shall not eliminate or limit
the liability of a director (i) for any breach of the director's duty of loyalty
to the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL regarding the unlawful payment of dividends
or approval of unlawful stock repurchases or redemptions, or (iv) for any
transaction from which the director derived an improper personal benefit. No
such provision shall eliminate or limit the liability of a director for any act
or omission occurring prior to the date when such provision becomes effective
(in the case of the Company, October 19, 1989). As noted in paragraph 3 below,
the Company's Amended and Restated Certificate of Incorporation (the "Company
Charter") includes a provision contemplated by Section 102(b)(7) of the DGCL.

         3. Certificate of Incorporation Provision on Liability of Directors.
The Company Charter eliminates the liability of its directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL. The Company Charter provides
that the Company's directors shall not be personally liable to the Company or
its stockholders for monetary damages for breach of their fiduciary duty as
directors, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) pursuant to Section 174 of the DGCL, or (iv) for any transactions
from which a director derived an improper personal benefit. This provision does
not eliminate the duty of care, and in appropriate circumstances equitable
remedies such as injunctive or other forms of nonmonetary relief are available
under Delaware law.

         4. Indemnification Agreements. The Company has entered or intends to
enter into Indemnification Agreements (the "Indemnification Agreements") with
its directors, officers and certain employees, agents, fiduciaries and designees
(each an "Authorized Representative"). The Indemnification Agreements authorize
the Company to pay all or part of certain expenses and liabilities of the
Authorized Representatives, either in advance or otherwise, upon written request
from such Authorized Representatives. The Indemnification Agreements indemnify
the Authorized Representatives in accordance with and to the maximum extent
permitted by the Company Charter and Sections 102(b)(7) and 145 of the DGCL, all
as described in the immediately preceding paragraphs.

         5. Director and Officer Liability Insurance. The Company maintains
director and officer liability insurance covering its directors and officers
with respect to certain liabilities which they may incur in connection with
their serving as such.

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 section 15(d) of the Securities Exchange Act of 1934, as
                  amended (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; and

                  (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 that is incorporated by reference in this registration statement
shall be deemed to be a new registration statement relating to the securities
offered herein, 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
Securities Act and is, therefore, unenforceable. In the event that a claim for




                                      -4-
<PAGE>   6

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.

No legal opinion with respect to the legality of the shares being registered is
being filed because no original issuance shares are sold under the Plan. The
Internal Revenue Service ("IRS") has determined that the Plan, as amended, meets
the requirements of Section 401 of the Internal Revenue Code. The Company hereby
undertakes that it will submit all amendments to the Plan subsequent to that
date to the IRS in a timely manner and that it will make all changes required by
the IRS in order to qualify the Plan under Section 401 of the Code.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         1. Section 145 of the Delaware General Corporation Law ("DGCL").
Section 145 of the DGCL provides that a corporation may indemnify any person who
was or is a party or is threatened to be made a party to
3

any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that the person is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding if the person 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, had no
reasonable cause to believe the person's conduct was unlawful. The termination
of any action, suit or proceeding by judgment, order, settlement or conviction,
or upon a plea of nolo contendere or its equivalent, shall not, of itself,
create a presumption that the person did not act 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, had
reasonable cause to believe that the person's conduct was unlawful.

         Section 145 also provides that a corporation may indemnify any person
who was or is a party or is threatened to be made a party to 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 the person is or was
a director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred by
the person in connection with the defense or settlement of such action or suit,
if the person acted in good faith and in a manner reasonably believed to be in
or not opposed to the best interests of the corporation, and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have 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,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

         To the extent that a former or present director or officer of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to above, or in defense of any claim, issue
or matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.

         Any such indemnification (unless ordered by a court) shall be made by
the corporation only as authorized in the specific case upon a determination
that the indemnification of the present or former director, officer, employee or
agent is proper in the circumstances because such person has met the applicable
standard of conduct set forth above. Such determination shall be made:

                  (1) by a majority vote of the directors who were not parties
         to such action, suit or proceeding, even though less than a quorum; or

                  (2) by a committee of such directors designated by a majority
         vote of such directors, even though less than a quorum; or

                  (3) if there are no such directors, or, if such directors so
         direct, by independent legal counsel in a written opinion; or

                  (4) by the stockholders.

         Section 145 permits a Delaware business corporation to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against any liability
asserted against such person and incurred by such person in any such capacity

                                      -2-
4

or arising out of such person's status as such, whether or not the corporation
would have the power to indemnify such person against such liability.

         2. Section 102(b)(7) of the DGCL. Section 102(b)(7) of the DGCL
provides that a corporation may set forth in its Certificate of Incorporation a
provision eliminating or limiting the personal liability of a director to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such provision shall not eliminate or limit
the liability of a director (i) for any breach of the director's duty of loyalty
to the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL regarding the unlawful payment of dividends
or approval of unlawful stock repurchases or redemptions, or (iv) for any
transaction from which the director derived an improper personal benefit. No
such provision shall eliminate or limit the liability of a director for any act
or omission occurring prior to the date when such provision becomes effective
(in the case of the Company, October 19, 1989). As noted in paragraph 3 below,
the Company's Amended and Restated Certificate of Incorporation (the "Company
Charter") includes a provision contemplated by Section 102(b)(7) of the DGCL.

         3. Certificate of Incorporation Provision on Liability of Directors.
The Company Charter eliminates the liability of its directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL. The Company Charter provides
that the Company's directors shall not be personally liable to the Company or
its stockholders for monetary damages for breach of their fiduciary duty as
directors, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) pursuant to Section 174 of the DGCL, or (iv) for any transactions
from which a director derived an improper personal benefit. This provision does
not eliminate the duty of care, and in appropriate circumstances equitable
remedies such as injunctive or other forms of nonmonetary relief are available
under Delaware law.

         4. Indemnification Agreements. The Company has entered or intends to
enter into Indemnification Agreements (the "Indemnification Agreements") with
its directors, officers and certain employees, agents, fiduciaries and designees
(each an "Authorized Representative"). The Indemnification Agreements authorize
the Company to pay all or part of certain expenses and liabilities of the
Authorized Representatives, either in advance or otherwise, upon written request
from such Authorized Representatives. The Indemnification Agreements indemnify
the Authorized Representatives in accordance with and to the maximum extent
permitted by the Company Charter and Sections 102(b)(7) and 145 of the DGCL, all
as described in the immediately preceding paragraphs.

         5. Director and Officer Liability Insurance. The Company maintains
director and officer liability insurance covering its directors and officers
with respect to certain liabilities which they may incur in connection with
their serving as such.

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 section 15(d) of the Securities Exchange Act of 1934, as
                  amended (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; and

                  (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 that is incorporated by reference in this registration statement
shall be deemed to be a new registration statement relating to the securities
offered herein, 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
Securities Act and is, therefore, unenforceable. In the event that a claim for

                                      -4-

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.

                 page to this Registration Statement.
No legal opinion with respect to the legality of the shares being registered is
being filed because no original issuance shares are sold under the Plan. The
Internal Revenue Service ("IRS") has determined that the Plan, as amended, meets
the requirements of Section 401 of the Internal Revenue Code. The Company hereby
undertakes that it will submit all amendments to the Plan subsequent to that
date to the IRS in a timely manner and that it will make all changes required by
the IRS in order to qualify the Plan under Section 401 of the Code.
