prior to the filing of a post-effective amendment which indicates that all

Item 6.  Indemnification of Directors and Officers

         The Company's and the subsidiary's Certificates of Incorporation
provides that the Company and the subsidiary will to the fullest extent
permitted by the General Corporation Law of the State of Delaware (the "DGCL"),
as amended from time to time, indemnify all persons whom it may indemnify
pursuant thereto. The Company's and the subsidiary's By-laws, as amended,
contain a similar provision requiring indemnification of the Company's and
subsidiary's directors and officers to the fullest extent authorized by the
DGCL.

         The DGCL permits a corporation to indemnify its directors and officers
(among others) against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by them in
connection with any action, suit or proceeding brought (or threatened to be
brought) by third parties, if such directors or officers acted in good faith and
in a manner they 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 their conduct was unlawful. In a
derivative action, i.e., one by or in the right of the corporation,
indemnification may be made for expenses (including attorneys' fees) actually
and reasonably incurred by directors and officers in connection with the defense
or settlement of such action if they had acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged 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. The DGCL further provides that, to the extent any
director or officer has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to in this paragraph, 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 him in
connection therewith.

         In addition, the subsidiary's Certificate of Incorporation contains a
provision limiting the personal liability of the subsidiary's directors for
monetary damages for certain breaches of their fiduciary duty.

         The Company and the subsidiary have indemnification insurance under
which directors and officers are insured against certain liability that may
occur in their capacity as such.

         The subsidiary has entered into indemnification agreements with each of
its directors and executive officers to give them additional contractual
assurances regarding the scope of the indemnification described above and to
provide additional procedural protections. Generally, pursuant to each
indemnification agreement, the subsidiary will indemnify a




                                       4
<PAGE>   5

director or officer who is or was a party to any legal action by or in the right
of the subsidiary or against the indemnitee due to his or her position as a
director or officer of the subsidiary, known as the "indemnitee," against the
expenses, judgments, fines and amounts paid in settlement that were actually and
reasonably incurred by the indemnitee in connection with such legal action,
provided that such indemnitee acted in good faith and in a manner not opposed to
the best interests of the subsidiary.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Securities Act"), may be permitted to directors,
officers and controlling persons of the Company or subsidiary pursuant to the
foregoing provisions, or otherwise, the Company and the subsidiary have 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.

Item 9.  Undertakings

         A. Post-Effective Amendments

            The Company and subsidiary 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 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 this Registration Statement.

         (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 this
               Registration Statement;

provided, however, that subparagraphs (i) and (ii) above will not apply if the
information required to be included in a post-effective amendment by those
subparagraphs is contained in periodic reports filed with or furnished to the
SEC by the registrant pursuant to Section 13 or 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 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.








                                       7
<PAGE>   8

         B.       Subsequent Documents Incorporated by Reference

                  The Company and subsidiary 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 will 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.       Claims for Indemnification

                  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company and subsidiary pursuant to the foregoing provisions, or
otherwise, the Company and the subsidiary have been advised that in the opinion
of the SEC 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 Company
and/or subsidiary of expenses incurred or paid by a director, officer or
controlling person of the Company and/or subsidiary 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
Company and/or the subsidiary 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.

         All documents subsequently filed by the Company or the Subsidiary with
the SEC pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act,
prior to the filing of a post-effective amendment which indicates that all

Item 6.  Indemnification of Directors and Officers

         The Company's and the subsidiary's Certificates of Incorporation
provides that the Company and the subsidiary will to the fullest extent
permitted by the General Corporation Law of the State of Delaware (the "DGCL"),
as amended from time to time, indemnify all persons whom it may indemnify
pursuant thereto. The Company's and the subsidiary's By-laws, as amended,
contain a similar provision requiring indemnification of the Company's and
subsidiary's directors and officers to the fullest extent authorized by the
DGCL.

         The DGCL permits a corporation to indemnify its directors and officers
(among others) against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by them in
connection with any action, suit or proceeding brought (or threatened to be
brought) by third parties, if such directors or officers acted in good faith and
in a manner they 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 their conduct was unlawful. In a
derivative action, i.e., one by or in the right of the corporation,
indemnification may be made for expenses (including attorneys' fees) actually
and reasonably incurred by directors and officers in connection with the defense
or settlement of such action if they had acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged 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. The DGCL further provides that, to the extent any
director or officer has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to in this paragraph, 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 him in
connection therewith.

         In addition, the subsidiary's Certificate of Incorporation contains a
provision limiting the personal liability of the subsidiary's directors for
monetary damages for certain breaches of their fiduciary duty.

         The Company and the subsidiary have indemnification insurance under
which directors and officers are insured against certain liability that may
occur in their capacity as such.

         The subsidiary has entered into indemnification agreements with each of
its directors and executive officers to give them additional contractual
assurances regarding the scope of the indemnification described above and to
provide additional procedural protections. Generally, pursuant to each
indemnification agreement, the subsidiary will indemnify a

                                       4
5

director or officer who is or was a party to any legal action by or in the right
of the subsidiary or against the indemnitee due to his or her position as a
director or officer of the subsidiary, known as the "indemnitee," against the
expenses, judgments, fines and amounts paid in settlement that were actually and
reasonably incurred by the indemnitee in connection with such legal action,
provided that such indemnitee acted in good faith and in a manner not opposed to
the best interests of the subsidiary.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Securities Act"), may be permitted to directors,
officers and controlling persons of the Company or subsidiary pursuant to the
foregoing provisions, or otherwise, the Company and the subsidiary have 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.

Item 9.  Undertakings

         A. Post-Effective Amendments

            The Company and subsidiary 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 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 this Registration Statement.

         (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 this
               Registration Statement;

provided, however, that subparagraphs (i) and (ii) above will not apply if the
information required to be included in a post-effective amendment by those
subparagraphs is contained in periodic reports filed with or furnished to the
SEC by the registrant pursuant to Section 13 or 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 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.

                                       7
8

         B.       Subsequent Documents Incorporated by Reference

                  The Company and subsidiary 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 will 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.       Claims for Indemnification

                  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company and subsidiary pursuant to the foregoing provisions, or
otherwise, the Company and the subsidiary have been advised that in the opinion
of the SEC 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 Company
and/or subsidiary of expenses incurred or paid by a director, officer or
controlling person of the Company and/or subsidiary 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
Company and/or the subsidiary 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.
