                  (2) The  Registrant's  Quarterly  Report  on Form 10-Q for the
         quarter  ended  June 28,  1998  filed  pursuant  to  Section  13 of the

                  (3) The  description  of the  Registrant's  Common Stock to be
         offered hereby which is contained in its Registration Statement on Form
         8-B filed  September  24, 1987, as amended by the  Registrant's  Form 8
         dated March 28, 1989 and the Registrant's  Form 8-B/A filed October 19,

Item 5.       Interests of Named Experts and Counsel.

              None.

Item 6.       Indemnification of Directors and Officers.

              Section  145 of the  Delaware  General  Corporation  Law permits a
corporation to grant indemnification to directors,  officers and other agents in
terms sufficiently broad to permit  indemnification  under certain circumstances
for liabilities,  including expenses,  arising in connection with the Securities
Act of 1933, as amended. Pursuant to the Bylaws of the Registrant, directors and
officers of the  Registrant are  indemnified to the fullest extent  permitted by
law  against all  expenses  (including  attorneys'  fees),  judgments,  fines or
settlement  amounts  incurred  or  paid by them  in any  action  or  proceeding,
including  any  action by or on behalf of the  Registrant,  on  account of their
service as an officer or director of the Registrant.  The Bylaws further provide
that the rights conferred under such Bylaws shall not be deemed exclusive of any
other  right to which  such  persons  may be  entitled  under  Delaware  General
Corporation  Law, the  Registrant's  Certificate  of  Incorporation,  any bylaw,
agreement,  vote of stockholders or  disinterested  directors or otherwise.  The
Restated Certificate of Incorporation of the Registrant, as amended,  precludes,
with certain  exceptions,  the Registrant and its  stockholders  from recovering
monetary  damages  from  directors  for  business  decisions  that  breach  such
directors' fiduciary duty.

              The  Registrant  also maintains  directors and officers  insurance
policies which insure directors and officers against losses arising from certain
wrongful acts in their  official  capacities  and  reimburses the Registrant for
such loss for which the  Registrant has lawfully  indemnified  the directors and
officers.  In  addition,  the  Registrant  has entered  into an  Indemnification
Agreement  with each of its directors and officers  whereby the  Registrant  has
agreed to  indemnify  each  director  and  officer  from and against any and all
expenses,  losses,  claims, damages and liabilities incurred by such director or
officer while acting in his or her official capacity.

              The   Underwriting   Agreement   among  the   Registrant  and  the
underwriters  of the  Registrant's  May 1995 public  offering  contains  certain
provisions pursuant to which the underwriters may, under certain  circumstances,
indemnify the directors and officers of the  Registrant.  Directors and officers
of the Registrant may also be  indemnified  in certain  circumstances  under the
terms  of  other  underwriting  agreements  entered  into by the  Registrant  in
connection with prior public offerings.

Item 7.       Exemption from Registration Claimed.

              Not applicable.

Item 8.       Exhibits.

Item 9.       Undertakings.

              (a) The undersigned Registrant hereby undertakes:

                           are being made,  a  post-effective  amendment to this
                           Registration Statement:

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

                           (ii)    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. Notwithstanding the foregoing, any
                                   increase or decrease in volume of  securities
                                   offered  (if  the  total   dollar   value  of
                                   securities  offered  would  not  exceed  that
                                   which was  registered) and any deviation from
                                   the low or high end of the estimated  maximum
                                   offering  range may be  reflected in the form
                                   of prospectus  filed with the  Securities and
                                   Exchange  Commission  pursuant to Rule 424(b)
                                   if, in the  aggregate,  the changes in volume
                                   and price represent no more than a 20 percent
                                   change  in  the  maximum  aggregate  offering
                                   price  set  forth  in  the   "Calculation  of
                                   Registration  Fee"  table  in  the  effective
                                   Registration Statement;

                           (iii)   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)(i)  and
                           (a)(1)(ii) do not apply if the Registration Statement
                           is on  Form  S-3,  Form  S-8 or  Form  F-3,  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
                           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 further 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  Securities  and  Exchange
                  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.

                  (1) The Registrant's Annual Report on Form 10-K for the fiscal
         year  ended  March  29,  1998,  filed  pursuant  to  Section  13 of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act").

                  (2) The  Registrant's  Quarterly  Report  on Form 10-Q for the
         quarter  ended  June 28,  1998  filed  pursuant  to  Section  13 of the
         Exchange Act.

                  (3) The  description  of the  Registrant's  Common Stock to be
         offered hereby which is contained in its Registration Statement on Form
         8-B filed  September  24, 1987, as amended by the  Registrant's  Form 8
         dated March 28, 1989 and the Registrant's  Form 8-B/A filed October 19,
         1995,  and the  Registrant's  Registration  Statement on Form 8-A dated
         December 20, 1988, as amended by the Registrant's Form 8 dated February
         27, 1992 and the Registrant's Form 8-A/A filed October 19, 1995.

              All documents  filed by the Registrant  pursuant to Sections 13(a)
and (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 securities  offered have been sold or which  deregisters 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.

Item 4.       Description of Securities.

              Not applicable.

                                      -2-
Item 5.       Interests of Named Experts and Counsel.

              None.

Item 6.       Indemnification of Directors and Officers.

              Section  145 of the  Delaware  General  Corporation  Law permits a
corporation to grant indemnification to directors,  officers and other agents in
terms sufficiently broad to permit  indemnification  under certain circumstances
for liabilities,  including expenses,  arising in connection with the Securities
Act of 1933, as amended. Pursuant to the Bylaws of the Registrant, directors and
officers of the  Registrant are  indemnified to the fullest extent  permitted by
law  against all  expenses  (including  attorneys'  fees),  judgments,  fines or
settlement  amounts  incurred  or  paid by them  in any  action  or  proceeding,
including  any  action by or on behalf of the  Registrant,  on  account of their
service as an officer or director of the Registrant.  The Bylaws further provide
that the rights conferred under such Bylaws shall not be deemed exclusive of any
other  right to which  such  persons  may be  entitled  under  Delaware  General
Corporation  Law, the  Registrant's  Certificate  of  Incorporation,  any bylaw,
agreement,  vote of stockholders or  disinterested  directors or otherwise.  The
Restated Certificate of Incorporation of the Registrant, as amended,  precludes,
with certain  exceptions,  the Registrant and its  stockholders  from recovering
monetary  damages  from  directors  for  business  decisions  that  breach  such
directors' fiduciary duty.

              The  Registrant  also maintains  directors and officers  insurance
policies which insure directors and officers against losses arising from certain
wrongful acts in their  official  capacities  and  reimburses the Registrant for
such loss for which the  Registrant has lawfully  indemnified  the directors and
officers.  In  addition,  the  Registrant  has entered  into an  Indemnification
Agreement  with each of its directors and officers  whereby the  Registrant  has
agreed to  indemnify  each  director  and  officer  from and against any and all
expenses,  losses,  claims, damages and liabilities incurred by such director or
officer while acting in his or her official capacity.

              The   Underwriting   Agreement   among  the   Registrant  and  the
underwriters  of the  Registrant's  May 1995 public  offering  contains  certain
provisions pursuant to which the underwriters may, under certain  circumstances,
indemnify the directors and officers of the  Registrant.  Directors and officers
of the Registrant may also be  indemnified  in certain  circumstances  under the
terms  of  other  underwriting  agreements  entered  into by the  Registrant  in
connection with prior public offerings.

Item 7.       Exemption from Registration Claimed.

              Not applicable.

Item 8.       Exhibits.

              (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:

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

                                      -3-
(ii)    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. Notwithstanding the foregoing, any
                                   increase or decrease in volume of  securities
                                   offered  (if  the  total   dollar   value  of
                                   securities  offered  would  not  exceed  that
                                   which was  registered) and any deviation from
                                   the low or high end of the estimated  maximum
                                   offering  range may be  reflected in the form
                                   of prospectus  filed with the  Securities and
                                   Exchange  Commission  pursuant to Rule 424(b)
                                   if, in the  aggregate,  the changes in volume
                                   and price represent no more than a 20 percent
                                   change  in  the  maximum  aggregate  offering
                                   price  set  forth  in  the   "Calculation  of
                                   Registration  Fee"  table  in  the  effective
                                   Registration Statement;

                           (iii)   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)(i)  and
                           (a)(1)(ii) do not apply if the Registration Statement
                           is on  Form  S-3,  Form  S-8 or  Form  F-3,  and  the
                           information    required   to   be   included   in   a
                           post-effective   amendment  by  those  paragraphs  is

                           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 further 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  Securities  and  Exchange
                  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,

                                      -4-
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.
