ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents filed by the Registrant with the Securities and
Exchange Commission are hereby incorporated by reference in this Registration
Statement:

         (a) Registrant's prospectus dated July 27, 2000 and filed on July 28,

<PAGE>

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Registrant's certificate of incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that directors of a corporation will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except liability for:

     o    any breach of their duty of loyalty to the corporation or its
          stockholders;

     o    acts or omissions not in good faith or which involve intentional
          misconduct or a knowing violation of law;

     o    unlawful payments of dividends or unlawful stock repurchases or
          redemptions as provided in Section 17 of the Delaware General
          Corporation Law; or

     o    any transaction from which the director derived an improper personal
          benefit.

         This limitation of liability does not apply to liabilities arising
under the federal securities laws and does not affect the availability of
equitable remedies such as injunctive relief or rescission.

         Registrant's certificate of incorporation and bylaws provide that it
will indemnify its directors and executive officers and may indemnify other
officers and employees and other agents to the fullest extent permitted by law.
Registrant's bylaws also permit it to secure insurance on behalf of any officer,
director, employee or other agent for any liability arising out of his or her
actions in such capacity, regardless of whether the bylaws would permit
indemnification.

         Registrant has entered into agreements to indemnify its directors and
executive officers, in addition to indemnification provided for in Registrant's
certificate of incorporation and bylaws. These indemnification agreements
require the Registrant to indemnify such director or officer (an "Indemnitee")
to the fullest extent permitted by Delaware law, and to indemnify such
Indemnitee against expenses and liabilities actually and reasonably incurred in
connection with the investigation, defense, settlement or appeal of any
proceeding to which such Indemnitee was or is threatened to be made a party.
Pursuant to these indemnification agreements, the Registrant shall also advance
to each Indemnitee expenses and costs associated with any above-referenced
proceeding.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8. EXHIBITS.

         See Exhibit Index, which list of exhibits is incorporated herein by

ITEM 9. UNDERTAKINGS.

         (a) The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made
of the securities registered hereby, a post-effective amendment to this
Registration Statement:

             (A) to include any prospectus required by Section 10(a)(3) of the
     Securities Act;

             (B) 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; and

             (C) 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)(A) and (a)(1)(B) 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 Exchange Act that are incorporated by
reference in the 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.

         (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 15(d) of the Exchange Act) 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.

         (c) 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 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 of 1933 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

                                      -3-

<PAGE>

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 of 1933 and will be governed by the final adjudication of such issue.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents filed by the Registrant with the Securities and
Exchange Commission are hereby incorporated by reference in this Registration
Statement:

         (a) Registrant's prospectus dated July 27, 2000 and filed on July 28,
2000 pursuant to Rule 424(b) of the Securities Act and which contains audited
financial statements for the Registrant's latest fiscal year for which such

         (c) The description of Registrant's Capital Stock contained in
Registrant's registration statement on Form 8-A, filed June 21, 2000 pursuant to

         Not applicable.

         The validity of the shares of common stock offered hereby has been

                                      -1-
ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Registrant's certificate of incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that directors of a corporation will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except liability for:

     o    any breach of their duty of loyalty to the corporation or its
          stockholders;

     o    acts or omissions not in good faith or which involve intentional
          misconduct or a knowing violation of law;

     o    unlawful payments of dividends or unlawful stock repurchases or
          redemptions as provided in Section 17 of the Delaware General
          Corporation Law; or

     o    any transaction from which the director derived an improper personal
          benefit.

         This limitation of liability does not apply to liabilities arising
under the federal securities laws and does not affect the availability of
equitable remedies such as injunctive relief or rescission.

         Registrant's certificate of incorporation and bylaws provide that it
will indemnify its directors and executive officers and may indemnify other
officers and employees and other agents to the fullest extent permitted by law.
Registrant's bylaws also permit it to secure insurance on behalf of any officer,
director, employee or other agent for any liability arising out of his or her
actions in such capacity, regardless of whether the bylaws would permit
indemnification.

         Registrant has entered into agreements to indemnify its directors and
executive officers, in addition to indemnification provided for in Registrant's
certificate of incorporation and bylaws. These indemnification agreements
require the Registrant to indemnify such director or officer (an "Indemnitee")
to the fullest extent permitted by Delaware law, and to indemnify such
Indemnitee against expenses and liabilities actually and reasonably incurred in
connection with the investigation, defense, settlement or appeal of any
proceeding to which such Indemnitee was or is threatened to be made a party.
Pursuant to these indemnification agreements, the Registrant shall also advance
to each Indemnitee expenses and costs associated with any above-referenced
proceeding.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8. EXHIBITS.

         See Exhibit Index, which list of exhibits is incorporated herein by
reference.

                                      -2-
ITEM 9. UNDERTAKINGS.

         (a) The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made
of the securities registered hereby, a post-effective amendment to this
Registration Statement:

             (A) to include any prospectus required by Section 10(a)(3) of the
     Securities Act;

             (B) 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; and

             (C) 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)(A) and (a)(1)(B) 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 Exchange Act that are incorporated by
reference in the 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.

         (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 15(d) of the Exchange Act) 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.

         (c) 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 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 of 1933 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

                                      -3-
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 of 1933 and will be governed by the final adjudication of such issue.

                                      -4-
