ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Reference is made to the Amended and Restated Certificate of Incorporation with
the Registrant; the Bylaws of the Registrant; Section 145 of the Delaware
General Corporation Law; which, among other things, and subject to certain
conditions, authorize the Registrant to indemnify, or indemnify by their terms,
as the case may be, the directors and officers of the Registrant against certain
liabilities and expenses incurred by such persons in connection with claims made
by reason of their being such a director or officer. Pursuant to this authority,
the Registrant has entered into an indemnification agreement with each director
and executive officer, whereby the Registrant has agreed to cover the
indemnification obligations.

The Registrant maintains directors' and officers' insurance providing
indemnification against certain liabilities for certain of the Registrant's
directors, officers, affiliates, partners or employees.

The indemnification provisions in the Registrant's Bylaws, and the
indemnification agreements entered into between the Registrant and its directors
and executive officers, may be sufficiently broad to permit indemnification of
the Registrant's officers and directors for liabilities arising under the Act.

Reference is made to the following documents incorporated by reference into this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein: (1) the Amended and Restated Certificate of
Incorporation, filed as Exhibit 3.1B to Registrant's Amendment No. 2 to
Registration Statement on Form S-1 filed with the Securities and Exchange
Commission on July 6, 1999; (2) the Registrant's Bylaws filed as Exhibit 3.1 to
Registrant's Quarterly Report on Form 10-Q for the quarter ended June 30, 2002,
and (3) the form of Indemnification Agreement entered into by the Registrant
with each of its directors and executive officers filed as Exhibit 10.1 to
Registrant's Registration Statement on Form S-1 filed with the Securities and
Exchange Commission on May 4, 1999, each incorporated by reference into this
Registration Statement.

ITEM 17.  UNDERTAKINGS

     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  provisions  described in Item 15 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
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 Act and will
be governed by the final adjudication of such issue.

         The undersigned Registrant hereby undertakes:

(1)      To file, during any period in which offers or sales are being made
         pursuant 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 percent 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
         distribution not previously disclosed in the registration statement or
         any material change to such information in the registration statement;

(2)      That, for the purpose of determining any 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; 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.

     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  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.

                                      II-2

     The undersigned  Registrant undertakes that: (1) for purpose of determining
any liability under the Securities Act of 1933, the information omitted from the
form of prospectus filed as part of the 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 the registration  statement as of the time it was declared effective;
and (2) for the purpose of determining any liability under the Securities Act of
1933, 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.

                                   SIGNATURES

     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-3 and has  duly  caused  this  Registration
Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
