are  incorporated  in this  Registration  Statement  by  reference  as of  their

         (a) The  Registrant's  Annual  Report on Form 10-K for the fiscal  year
         ended  December  31,  1995 filed  pursuant  to the  Exchange  Act which

         (b) The  Registrant's  Quarterly  Report  on Form  10-Q for the  fiscal

Item 4.  Description of Securities.

         Not applicable.

Item 5.  Interest of Named Experts and Counsel.

         The validity of the Common Stock  offered  hereby has been passed on by
Testa, Hurwitz & Thibeault,  LLP, 125 High Street, Boston,  Massachusetts 02110,
which serves as general counsel to the Registrant. Richard J. Testa, a member of
the  firm  and  Clerk,  Secretary  and  a  director  of  the  Registrant,   owns
beneficially 12,500 shares of Common Stock of the Registrant.

Item 6.  Indemnification of Directors and Officers.

         Section 67 of the Massachusetts Business Corporation Law ("Section 67")
provides  that a  corporation  may  indemnify  its directors and officers to the
extent  specified in or authorized by (i) the articles of  organization,  (ii) a
by-law adopted by the stockholders,  or (iii) a vote adopted by the holders of a
majority of the shares of stock  entitled to vote on the election of  directors.
In all instances,  the extent to which a corporation provides indemnification to
its  directors and officers  under Section 67 is optional.  Article VI ("Article
Six")  of the  Registrant's  Restated  Articles  of  Organization,  as  amended,
provides  indemnification  to the  Registrant's  directors  and  officers to the
fullest extent permitted by Massachusetts law, including  circumstances in which
indemnification  is  otherwise  discretionary.  Section 2 of  Article  VI of the
Registrant's  Amended and  Restated  By-laws  provides  that each  director  and
officer shall be indemnified by the Registrant against  liabilities and expenses
in  connection  with any legal  proceeding to which such officer or director may
become a party by reason of being or having  been an officer or  director of the
Registrant or of any organization in which the Registrant directly or indirectly
owns shares or of which the  Registrant  is a creditor,  and  provides  that the
Board  of  Directors  of  the  Registrant  may,  without  stockholder  approval,
authorize the Registrant to enter into  agreements,  including any amendments or
modifications  thereto,  with any of its  directors  or officers  providing  for
indemnification  of such person to the maximum extent permitted under applicable
law and the  Registrant's  Restated  Articles of Organization,  as amended,  and
Amended and Restated By-Laws.

         Article Six  eliminates  the  personal  liability  of the  Registrant's
directors for monetary  damages for breach of their  fiduciary duty as directors
to the Registrant  and its  stockholders,  notwithstanding  any provision of law
imposing such liability.  Article Six does not, however,  eliminate liability of
the  Registrant's  directors (i) for breach of the director's duty of loyalty to
the Registrant or its stockholders, (ii) for acts or omissions not in good faith
or which involve  intentional  misconduct or a knowing  violation of law,  (iii)
under Section 61 or 62 of the  Massachusetts  Business  Corporation Law, or (iv)
for any  transaction  from  which the  director  derived  an  improper  personal
benefit.

         The  Registrant and its directors and officers are covered by liability
insurance. In addition, the directors and officers of the Registrant are covered
by individual indemnification agreements with the Registrant.

Item 7.  Exemption From Registration Claimed.

         Not applicable.

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 of 1933;
                           
                           (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 Commission pursuant to Rule
                           424(b) if, in the  aggregate,  the  changes in volume
                           and price  represent no more than a 20% 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;

                  (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


                                      -6-

                  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 of 1933, each filing
         of the Registrant's  annual report pursuant to Section 13(a) or Section
         15(d) of the Securities  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.
