ITEM 5.     INTERESTS OF NAMED EXPERTS AND COUNSEL

      Not Applicable

ITEM 6.     INDEMNIFICATION OF DIRECTORS AND OFFICERS

      The Company is a Delaware corporation. Reference is made to Section 145 of
the Delaware General Corporation Law as to indemnification by the Company of its
officers and directors. The general effect of such law is to empower a
corporation to indemnify any of its officers and directors against certain
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person to be indemnified in
connection with certain actions, suits or proceedings (threatened, pending or
completed) if the person to be indemnified acted in good faith and in a manner
he 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 his conduct was unlawful.

      The Amended and Restated By-Laws of the Company, as amended by the
Amendment to the Amended and Restated By-laws (the "By-Laws") (which are
incorporated herein by reference as Exhibits 4.4 and 4.5, respectively, to this
Registration Statement) provide for indemnification of any person who was or is
a director, officer, employee

<PAGE>   4

or agent of the Company or was serving in such capacity at another entity at the
Company's request (each, an "Indemnified Person"), and is a party to, or is
threatened to be made a party to, any threatened, pending or completed action,
suit or proceeding, whether derivative or not. Indemnification continues as to
an Indemnified Person who has ceased to be a director, officer, employee or
agent and inures to the benefit of the heirs, executors and administrators of an
Indemnified Person. The By-Laws also authorize indemnification for expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement, as
well as the advancement of expenses to an Indemnified Person. The
indemnification provisions in the By-Laws are non-exclusive and allow the
Company to indemnify by agreement or vote of stockholders or disinterested
directors.

      Article Eighth of the Company's Amended and Restated Certificate of
Incorporation (the "Certificate of Incorporation") (which is incorporated by
reference as Exhibit 4.3 to this Registration Statement) provides for the
indemnification of the Company's directors in accordance with the Delaware
General Corporation Law, and includes, as permitted by the Delaware General
Corporation Law, certain limitations on the potential personal liability of
members of the Company's Board of Directors for monetary damages as a result of
actions taken in their capacity as Board members.

      The directors and officers of the Company are covered by insurance
policies indemnifying them against certain liabilities arising under the
Securities Act which might be incurred by them in such capacities.

ITEM 9.     UNDERTAKINGS

      (a) The undersigned Company and the Plans hereby undertake:

      (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 this
      Registration Statement. Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20% change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      this effective 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 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 with or furnished to the
Commission 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 being registered which remain unsold at the termination of the
offering.

      (4) To submit the Plans and any amendments thereto to the Internal Revenue
Service (the "IRS") in a timely manner and to make all changes required by the
IRS to qualify the Plans.

      (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 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section


                                      II-3
<PAGE>   6

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 Company pursuant to the indemnification provisions summarized in Item 6
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 expenses incurred or paid by the 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 Company 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.

ITEM 5.     INTERESTS OF NAMED EXPERTS AND COUNSEL

ITEM 6.     INDEMNIFICATION OF DIRECTORS AND OFFICERS

      The Company is a Delaware corporation. Reference is made to Section 145 of
the Delaware General Corporation Law as to indemnification by the Company of its
officers and directors. The general effect of such law is to empower a
corporation to indemnify any of its officers and directors against certain
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person to be indemnified in
connection with certain actions, suits or proceedings (threatened, pending or
completed) if the person to be indemnified acted in good faith and in a manner
he 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 his conduct was unlawful.

      The Amended and Restated By-Laws of the Company, as amended by the
Amendment to the Amended and Restated By-laws (the "By-Laws") (which are
incorporated herein by reference as Exhibits 4.4 and 4.5, respectively, to this
Registration Statement) provide for indemnification of any person who was or is
a director, officer, employee
4

or agent of the Company or was serving in such capacity at another entity at the
Company's request (each, an "Indemnified Person"), and is a party to, or is
threatened to be made a party to, any threatened, pending or completed action,
suit or proceeding, whether derivative or not. Indemnification continues as to
an Indemnified Person who has ceased to be a director, officer, employee or
agent and inures to the benefit of the heirs, executors and administrators of an
Indemnified Person. The By-Laws also authorize indemnification for expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement, as
well as the advancement of expenses to an Indemnified Person. The
indemnification provisions in the By-Laws are non-exclusive and allow the
Company to indemnify by agreement or vote of stockholders or disinterested
directors.

      Article Eighth of the Company's Amended and Restated Certificate of
Incorporation (the "Certificate of Incorporation") (which is incorporated by
reference as Exhibit 4.3 to this Registration Statement) provides for the
indemnification of the Company's directors in accordance with the Delaware
General Corporation Law, and includes, as permitted by the Delaware General
Corporation Law, certain limitations on the potential personal liability of
members of the Company's Board of Directors for monetary damages as a result of
actions taken in their capacity as Board members.

      The directors and officers of the Company are covered by insurance
policies indemnifying them against certain liabilities arising under the
Securities Act which might be incurred by them in such capacities.

ITEM 9.     UNDERTAKINGS

      (a) The undersigned Company and the Plans hereby undertake:

      (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 this
      Registration Statement. Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20% change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      this effective 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 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 with or furnished to the
Commission 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 being registered which remain unsold at the termination of the
offering.

      (4) To submit the Plans and any amendments thereto to the Internal Revenue
Service (the "IRS") in a timely manner and to make all changes required by the
IRS to qualify the Plans.

      (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 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section

                                      II-3
6

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 Company pursuant to the indemnification provisions summarized in Item 6
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 expenses incurred or paid by the 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 Company 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.
