ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Article EIGHTH of the Registrant's Certificate of Incorporation (the
"Certificate of Incorporation") provides that no director of the Registrant
shall be personally liable for any monetary damages for any breach of
fiduciary duty as a director, except to the extent that the Delaware General
Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty.

Article NINTH of the Certificate of Incorporation provides that a director
or officer of the Registrant (a) shall be indemnified by the Registrant
against all expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement incurred in connection with any litigation or other legal
proceeding (other than an action by or in the right of the Registrant) brought
against him by virtue of his position as a director or officer of the
Registrant if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to the best interests of the Registrant, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful and (b) shall be indemnified by the
Registrant against all expenses (including attorneys' fees) and amounts paid
in settlement incurred in connection with any action by or in the right of the
Registrant brought against him by virtue of his position as a director or
officer of the Registrant if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, except that no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
Registrant, unless the Court of Chancery of Delaware determines that, despite
such adjudication but in view of all of the circumstances, he is entitled to
indemnification of such expenses. Notwithstanding the foregoing, to the extent
that a director or officer has been successful, on the merits or otherwise,
including, without limitation, the dismissal of an action without prejudice,
he is required to be indemnified by the Registrant against all expenses
(including attorneys' fees) actually and reasonably incurred in connection
therewith. In the event the Registrant does not assume the defense of an
action in accordance with the Certificate of Incorporation, expenses shall be
advanced to a director or officer at his request prior to the final
disposition of the matter, provided that he undertakes to repay the amount
advanced if it is ultimately determined that he is not entitled to
indemnification for such expenses.

Indemnification is required to be made unless the Registrant determines that
the applicable standard of conduct required for indemnification has not been
met. In the event of a determination by the Registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the Registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent
to the right of indemnification, the director, or officer must give the
Registrant notice of the action for which indemnity is sought and the
Registrant has the right to participate in such action or assume the defense
thereof.

II-1

Article NINTH of the Certificate of Incorporation further provides that the
indemnification provided therein is not exclusive, and provides that in the
event that the Delaware General Corporation Law is amended to expand the
indemnification permitted to directors or officers the Registrant must
indemnify those persons to the fullest extent permitted by such law as so
amended.

Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred
in connection with an action or proceeding to which he is or is threatened to
be made a party by reason of such position, if such person shall have 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, in any criminal proceeding, if
such person had no reasonable cause to believe his conduct was unlawful;
provided, that, in the case of actions brought by or in the right of the
corporation, no indemnification shall be made with respect to any matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.

Pursuant to the Underwriting Agreement, the Underwriters are obligated,
under certain circumstances, to indemnify directors and officers of the
Registrant against certain liabilities, including liabilities under the
Securities Act. Reference is made to the form of Underwriting Agreement filed
as Exhibits 1 hereto.

The Company has purchased a general liability insurance policy which covers
certain liabilities of directors and officers of the Company arising out of
claims based on acts or omissions in their capacities as directors and
officers.

ITEM 17. 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;

(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. 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 the effective 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 this registration statement;

Provided, however, that paragraphs (i) and (ii) above 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 that are incorporated by reference in this registration statement.

(2) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended, 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) As to documents subsequently filed that are incorporated by
reference: The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, each filing
of the registrant's annual report pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 (and each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934, as applicable) 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.

(B) 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 provisions contained in the Certificate of
Incorporation and Amended and Restated By-Laws of the Registrant and the laws
of the State of Delaware, 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 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.

II-5

(C) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.

(D) The undersigned Registrant hereby undertakes that:

(1) For the purposes of determining any liability under the Securities
Act, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
(4) or 497(h) under the Securities Act shall be deemed to be part of this
Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains a form of prospectus 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.
