               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference.
-------  -----------------------------------------

         All documents filed by Registrant pursuant to Sections 13(a), 13(c), 14
or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), subsequent to the date of the filing of this Registration Statement and
prior to the filing of a post-effective amendment to the Registration Statement
which indicates that all securities registered under this Registration Statement
have been sold or which deregisters all securities then remaining unsold shall
be deemed to be incorporated by reference into this Registration Statement and
to be a part hereof from the date of the filing of such documents.

         The following documents filed with the Commission (File No. 0-19974)
are incorporated in this Registration Statement by reference:

                  (a) Registrant's Annual Report on Form 10-K for the year ended
         December 31, 2003.

                  (b) Registrant's Current Report on Form 8-K filed on April 13,
         2004.

                  (c) Registrant's Quarterly Report on Form 10-Q for quarter
         ended March 31, 2004.

         There is incorporated in this Registration Statement by reference the
description of Registrant's Common Stock contained in Registrant's Prospectus
(Subject to Completion) in Registrant's Registration Statement on Form S-1
(Registration No. 33-45734) filed with the Commission on February 14, 1992,
which description was incorporated by reference into Registrant's Registration
Statement on Form 8-A dated March 19, 1992 filed with the Commission under the
Exchange Act on March 21, 1992.

Item 4.  Description of Securities.
-------  --------------------------

                  Not applicable.

Item 5.  Interests of Named Experts and Counsel.
-------  ---------------------------------------

                  Not applicable.

Item 6.  Indemnification of Directors and Officers.
-------  ------------------------------------------

         Section 145 of the General Corporation Law of Delaware (the "GCL")
permits, and under certain circumstances requires, Registrant to indemnify its
directors, officers, employees and agents subject to certain conditions and
limitations. Article VII of Registrant's Bylaws requires it to indemnify
directors and permits it to indemnify officers, employees and agents to the full
extent permitted by the GCL. Registrant has also entered into Indemnity
Agreements with its officers pursuant to which Registrant has agreed to
indemnify them. The Indemnity Agreements require indemnification of officers,
under circumstances in which such indemnification would otherwise be
discretionary, unless Registrant sustains the burden of proving that the officer
has not met the applicable standard of conduct. Registrant is not obligated to
make any payment prohibited by law. Registrant's Bylaws, together with the
Indemnity Agreements, expand its indemnification obligations to the full extent
permitted by law. While Delaware law contemplates some expansion of
indemnification beyond what is specifically authorized by the GCL, the courts
have not yet established the boundaries of permissible indemnification.

Item 9.  Undertakings.
-------  -------------

                  (i) 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:

                           (A) To include any prospectus required by Section
                  10(a)(3) of the Securities Act of 1933;

                           (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;

                           (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;


                                      II-2


                  provided, however, that paragraphs (a)(1)(i) and (a) (1) (ii)
                  do not apply if the registration statement is on Form S-3 or
                  Form S-8 and 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 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
                           bonafide 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.

                           (ii) 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, where applicable, each
                  filing of an employee benefit plan's annual report pursuant to
                  Section 15(d) of the Securities Exchange Act of 1934) 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
                  bonafide offering thereof.

                           (iii) 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 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.
