                           INFORMATION REQUIRED IN THE
                             REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

     The following documents filed by the Registrant with the Commission are

     a. The Registrant's Annual Report on Form 10-K for the fiscal year ended
April 7, 2001 which includes audited financial statements for the Registrant's

     b. All other reports filed by the Registrant pursuant to Section 13(a) or

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
that they may incur in such capacities, including liabilities under the
Securities Act. The Registrant's Restated Bylaws also provide for mandatory
indemnification of its directors and executive officers, to the fullest extent
permissible under Delaware law.

     The Registrant's Restated Certificate of Incorporation limits the liability
of directors to the maximum extent permitted by Delaware law. Delaware law
provides that directors of a company will not be personally liable to the
company or its stockholders for monetary damages for breach of their fiduciary
duties as directors, except liability for (i) any breach of their duty of
loyalty to the company or its stockholders, (ii) acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) unlawful payments of dividends or unlawful stock repurchases or
redemptions or (iv) any transaction from which the directors derived an improper
personal benefit. The Restated Certificate of Incorporation also provides that
the Registrant shall indemnify any director or officer to the maximum extent
provided by Delaware law, and that such right of indemnification shall continue
as to a person who has ceased to be a director or officer of the Registrant.
Responsibility for determinations with respect to such indemnification will be
made by the Board of Directors.

     In addition the Registrant has entered into indemnity agreements with its
directors and certain of its executive officers that require the Registrant to
indemnify such persons against expenses, judgments, fines, settlements and other
amounts actually and reasonably incurred (including expenses of a derivative
action) in connection with any proceeding, whether actual or threatened, to
which any such person may be made a party by reason of the fact that such person
is or was a director or officer of the Registrant or any of its affiliated
enterprises, provided such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
Registrant and, with respect to any criminal proceeding, had no reasonable cause
to believe his or her conduct was unlawful. The indemnification agreements also
set forth certain procedures that will apply in the event of a claim for
indemnification thereunder.

     The Registrant has obtained a policy of directors' and officers' liability
insurance that insures the Registrant's directors and officers against the cost
of defense, settlement or payment of a judgement under certain circumstances.

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, 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 15(d) of the Exchange
Act 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 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 the
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.

of the Securities Act of 1933, as amended (the "Securities Act").

                                     PART II
                           INFORMATION REQUIRED IN THE
                             REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

     The following documents filed by the Registrant with the Commission are
incorporated by reference herein:

     a. The Registrant's Annual Report on Form 10-K for the fiscal year ended
April 7, 2001 which includes audited financial statements for the Registrant's
latest fiscal year.

     b. All other reports filed by the Registrant pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
since the end of the fiscal year covered by the audited financial statements
described in (a) above.

     c. The description of the Registrant's Common Stock contained in the
Registrant's Statement on Form 8-A, filed February 15, 1994 under the Exchange
Act, including any amendment or report filed for the purpose of updating such
description.

     All documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Exchange Act after the date of this Registration Statement, and
prior to the filing of a post-effective amendment which indicates that all

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. Any statement contained in a document incorporated by reference
herein shall be 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 which also is or is deemed to be incorporated
by reference herein modifies or supersedes such statement. Any statement so

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
that they may incur in such capacities, including liabilities under the
Securities Act. The Registrant's Restated Bylaws also provide for mandatory
indemnification of its directors and executive officers, to the fullest extent
permissible under Delaware law.

     The Registrant's Restated Certificate of Incorporation limits the liability
of directors to the maximum extent permitted by Delaware law. Delaware law
provides that directors of a company will not be personally liable to the
company or its stockholders for monetary damages for breach of their fiduciary
duties as directors, except liability for (i) any breach of their duty of
loyalty to the company or its stockholders, (ii) acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) unlawful payments of dividends or unlawful stock repurchases or
redemptions or (iv) any transaction from which the directors derived an improper
personal benefit. The Restated Certificate of Incorporation also provides that
the Registrant shall indemnify any director or officer to the maximum extent
provided by Delaware law, and that such right of indemnification shall continue
as to a person who has ceased to be a director or officer of the Registrant.
Responsibility for determinations with respect to such indemnification will be
made by the Board of Directors.

     In addition the Registrant has entered into indemnity agreements with its
directors and certain of its executive officers that require the Registrant to
indemnify such persons against expenses, judgments, fines, settlements and other
amounts actually and reasonably incurred (including expenses of a derivative
action) in connection with any proceeding, whether actual or threatened, to
which any such person may be made a party by reason of the fact that such person
is or was a director or officer of the Registrant or any of its affiliated
enterprises, provided such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
Registrant and, with respect to any criminal proceeding, had no reasonable cause
to believe his or her conduct was unlawful. The indemnification agreements also
set forth certain procedures that will apply in the event of a claim for
indemnification thereunder.

     The Registrant has obtained a policy of directors' and officers' liability
insurance that insures the Registrant's directors and officers against the cost
of defense, settlement or payment of a judgement under certain circumstances.

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, 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 15(d) of the Exchange
Act 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 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 the
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.
