               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

      Item 3.  Incorporation of Documents by Reference

      This Registration Statement incorporates herein by reference the following
documents which have been filed with the Commission by the Registrant:

      1.    The Registrant's Annual Report on Form 10-K for the fiscal year
            ended September 30, 1999, filed pursuant to Section 13 of the
            Securities and Exchange Act of 1934 (the "Exchange Act").

      2.    The Registrant's Quarterly Reports on Form 10-Q for the fiscal
            quarters ended December 31, 1999 and March 31, 2000, filed pursuant
            to Section 13 of the Exchange Act.

      3.    The Registrant's Current Reports on Form 8-K, dated March 6, 2000,
            March 13, 2000, March 27, 2000, March 31, 2000 (as amended on May
            25, 2000 and June 7, 2000), April 10, 2000, April 19, 2000 and May
            31, 2000, filed pursuant to Section 13 of the Exchange Act.

      4.    The description of the Registrant's Common Stock, par value $.01 per
            share, contained in its registration statement on Form 8-A filed
            with the Securities and Exchange Commission on November 8, 1991,
            including any amendment or report filed for the purpose of updating
            such description.

      All other documents filed by the Company with the Commission pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act subsequent to the date
of this Registration Statement and prior to the filing of a post-effective
amendment to this Registration Statement which indicates that all securities
offered have been sold or which de-registers all securities then remaining
unsold, shall be deemed to be incorporated by reference in this Registration
Statement and to be a part hereof from the date of filing of such documents
(such documents, and the documents enumerated above, being hereinafter referred
to collectively as the "Incorporated Documents").

      Item 4.  Description of Securities.

            Not applicable.

      Item 5.  Interest of Named Experts and Counsel.

            Not applicable.

      Item 6.  Indemnification of Directors and Officers.

            The Registrant has adopted provisions in its Amended and Restated
Certificate of Incorporation which (i) eliminate the personal liability of its
directors to the Registrant and its shareholders for monetary damages arising
from a breach of their fiduciary duties in certain circumstances, and (ii)
authorize the Registrant to indemnify its directors and officers to the fullest
extent permitted by law. The limitation of liability does not affect the
availability of equitable remedies, such as injunctive relief or rescission. In
addition, the Registrant's bylaws provide that the Registrant shall indemnify
its directors and officers to the fullest extent permitted by applicable law.

            The Registrant has entered into separate indemnification agreements
with each of its officers and directors that contain provisions which are in
some respects broader than the specific indemnification provisions contained in
the Delaware General Corporation Law. The indemnification agreements may require
the Registrant, among other things, to indemnify such officers and directors
against certain liabilities that may arise by reason of their status or service
as directors or officers (other than liabilities arising from willful misconduct
of a culpable nature), to advance their expenses incurred as a result of any
proceeding against them as to which they could be indemnified, and to obtain
director's and officer's insurance, if available on reasonable terms.

      Item 7.  Exemption for Registration Claimed.

                  Not applicable.

      Item 8.     Exhibits.

         effective December 10, 1991)

         legality of securities being registered (filed herewith)

         Statement)


      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 (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 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 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.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

      Item 3.  Incorporation of Documents by Reference

      This Registration Statement incorporates herein by reference the following
documents which have been filed with the Commission by the Registrant:

      1.    The Registrant's Annual Report on Form 10-K for the fiscal year
            ended September 30, 1999, filed pursuant to Section 13 of the
            Securities and Exchange Act of 1934 (the "Exchange Act").

      2.    The Registrant's Quarterly Reports on Form 10-Q for the fiscal
            quarters ended December 31, 1999 and March 31, 2000, filed pursuant
            to Section 13 of the Exchange Act.

      3.    The Registrant's Current Reports on Form 8-K, dated March 6, 2000,
            March 13, 2000, March 27, 2000, March 31, 2000 (as amended on May
            25, 2000 and June 7, 2000), April 10, 2000, April 19, 2000 and May
            31, 2000, filed pursuant to Section 13 of the Exchange Act.

      4.    The description of the Registrant's Common Stock, par value $.01 per
            share, contained in its registration statement on Form 8-A filed
            with the Securities and Exchange Commission on November 8, 1991,
            including any amendment or report filed for the purpose of updating
            such description.

      All other documents filed by the Company with the Commission pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act subsequent to the date
of this Registration Statement and prior to the filing of a post-effective
amendment to this Registration Statement which indicates that all securities
offered have been sold or which de-registers all securities then remaining
unsold, shall be deemed to be incorporated by reference in this Registration
Statement and to be a part hereof from the date of filing of such documents
(such documents, and the documents enumerated above, being hereinafter referred
to collectively as the "Incorporated Documents").

      Item 4.  Description of Securities.

            Not applicable.

      Item 5.  Interest of Named Experts and Counsel.

            Not applicable.

      Item 6.  Indemnification of Directors and Officers.

            The Registrant has adopted provisions in its Amended and Restated
Certificate of Incorporation which (i) eliminate the personal liability of its
directors to the Registrant and its shareholders for monetary damages arising
from a breach of their fiduciary duties in certain circumstances, and (ii)
authorize the Registrant to indemnify its directors and officers to the fullest
extent permitted by law. The limitation of liability does not affect the
availability of equitable remedies, such as injunctive relief or rescission. In
addition, the Registrant's bylaws provide that the Registrant shall indemnify
its directors and officers to the fullest extent permitted by applicable law.

            The Registrant has entered into separate indemnification agreements
with each of its officers and directors that contain provisions which are in
some respects broader than the specific indemnification provisions contained in
the Delaware General Corporation Law. The indemnification agreements may require
the Registrant, among other things, to indemnify such officers and directors
against certain liabilities that may arise by reason of their status or service
as directors or officers (other than liabilities arising from willful misconduct
of a culpable nature), to advance their expenses incurred as a result of any
proceeding against them as to which they could be indemnified, and to obtain
director's and officer's insurance, if available on reasonable terms.

      Item 7.  Exemption for Registration Claimed.

                  Not applicable.

      Item 8.     Exhibits.

                                        2
The following are filed as part of this Registration Statement:

         effective December 10, 1991)

5.1      Opinion of Davis Polk & Wardwell (Counsel to the Registrant) as to the
         legality of securities being registered (filed herewith)

23.1     Consent of KPMG LLP (filed herewith)

         Statement)

      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 (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 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 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.
