       The following documents previously filed with the Commission by the
Company are incorporated in this Prospectus by reference:


       1.     the Company's Annual Report on Form 10-K for the fiscal year ended
              February 29, 2000;

       2.     all other reports filed pursuant to Section 13(a) or 15(d) of the
              Securities Exchange Act of 1934, as amended (the "Exchange Act"),

              document referred to in (1) above; and

or 15(d) of the Exchange Act after the date of this registration statement and
prior to the termination of the offering of the Common Stock shall be deemed to

deemed to be modified or superseded for purposes of this registration statement
to the extent that a statement contained herein or in any other subsequently
filed document that also is or is deemed to be incorporated by reference herein

ITEM   5.     INTERESTS OF NAMED EXPERTS AND COUNSEL

       The law firm of Dilworth Paxson LLP has rendered an opinion regarding the
legality of the shares of Common Stock. At November 29, 2000, Mr. Jacovini was
the beneficial owner of 192,000 shares of Common Stock (including 2,672 shares
of Common Stock held by his spouse and a total of 73,328 shares of Common Stock
issuable upon exercise of certain options).


ITEM   6.     INDEMNIFICATION OF OFFICERS AND DIRECTORS

<PAGE>   4


       The Company's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") contains certain provisions permitted under the
General Corporation Law of Delaware, as amended ("Delaware GCL") which eliminate
the personal liability of directors for monetary damages for a breach of the
director's fiduciary duty, except for: (i) breach of a director's duty of
loyalty; (ii) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) the unlawful payment of
dividends, stock purchase or stock redemption, or (iv) any transaction from
which the director derives any improper personal benefit. The Certificate of
Incorporation also contains provisions indemnifying the Company's directors,
officers and employees to the fullest extent permitted by the Delaware GCL. The
Company believes that these provisions will assist the Company in attracting and
retaining qualified individuals to serve as directors, officers and employees.

       The Company's directors and officers are also insured against certain
liabilities under a directors and officers liability insurance policy maintained
by the Company.

ITEM   9.     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 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.

              (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 herein, and
                     the offering of such securities at that time shall be
                     deemed to be the initial bona fide offering thereof.

<PAGE>   5

              (3)    To remove from registration by means of a post-effective
                     amendment any of the securities being registered which
                     remain unsold at the end of the offering.

       B.     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 15(d) of the 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 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 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.

Company are incorporated in this Prospectus by reference:

       1.     the Company's Annual Report on Form 10-K for the fiscal year ended
              February 29, 2000;

       2.     all other reports filed pursuant to Section 13(a) or 15(d) of the
              Securities Exchange Act of 1934, as amended (the "Exchange Act"),

              document referred to in (1) above; and

or 15(d) of the Exchange Act after the date of this registration statement and
prior to the termination of the offering of the Common Stock shall be deemed to

deemed to be modified or superseded for purposes of this registration statement
to the extent that a statement contained herein or in any other subsequently
filed document that also is or is deemed to be incorporated by reference herein

ITEM   5.     INTERESTS OF NAMED EXPERTS AND COUNSEL

       The law firm of Dilworth Paxson LLP has rendered an opinion regarding the
legality of the shares of Common Stock. At November 29, 2000, Mr. Jacovini was
the beneficial owner of 192,000 shares of Common Stock (including 2,672 shares
of Common Stock held by his spouse and a total of 73,328 shares of Common Stock
issuable upon exercise of certain options).

ITEM   6.     INDEMNIFICATION OF OFFICERS AND DIRECTORS
4

       The Company's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") contains certain provisions permitted under the
General Corporation Law of Delaware, as amended ("Delaware GCL") which eliminate
the personal liability of directors for monetary damages for a breach of the
director's fiduciary duty, except for: (i) breach of a director's duty of
loyalty; (ii) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) the unlawful payment of
dividends, stock purchase or stock redemption, or (iv) any transaction from
which the director derives any improper personal benefit. The Certificate of
Incorporation also contains provisions indemnifying the Company's directors,
officers and employees to the fullest extent permitted by the Delaware GCL. The
Company believes that these provisions will assist the Company in attracting and
retaining qualified individuals to serve as directors, officers and employees.

       The Company's directors and officers are also insured against certain
liabilities under a directors and officers liability insurance policy maintained
by the Company.

ITEM   9.     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 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.

              (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 herein, and
                     the offering of such securities at that time shall be
                     deemed to be the initial bona fide offering thereof.
5

              (3)    To remove from registration by means of a post-effective
                     amendment any of the securities being registered which
                     remain unsold at the end of the offering.

       B.     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 15(d) of the 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 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 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.
