              quarter ended  September 28, 1997 filed  pursuant to Section 13 of

                  (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

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:

                   (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-

<PAGE>

                        (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,

<PAGE>

                  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.

                  (2) The  Registrant's  Quarterly  Report  on Form 10-Q for the
              quarter ended  September 28, 1997 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

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.

              See Index to Exhibits.

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:

                        (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

                        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,

                                       -4-
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.
