     (1)   Estimated solely for the purpose of determining the registration fee
pursuant to Rule 457 under the Securities Act of 1933, on the basis of the
average high and low prices for the Registrant's Common Stock on October 17,
1995, as reported by the American Stock Exchange, Inc.

     (2)   Such presently indeterminable number of additional shares of Common
Stock and Rights (see below) are also registered hereunder as may be issued in
the event of a merger, consolidation, reorganization, recapitalization, stock
dividend, stock split or other similar change in Common Stock.

     (3)   On November 20, 1986, the Board of Directors of the Company declared
a dividend distribution of one right (the "Rights") for each outstanding share
of Common Stock. The 50,000 Rights registered hereby consist of 50,000 Rights
which may be issued with shares of Common Stock issuable upon exercise of
options granted or to be granted under the Company's 1994 Non-Qualified Stock
Option Plan for Non-Employee Directors.

     (4)   The Rights are not separately transferable apart from the Common
Stock, nor are they exercisable until the occurrence of certain events.
Accordingly, no independent value has been attributed to the Rights.

ITEM 4.   DESCRIPTION OF SECURITIES.
          ------------------------- 

     Not applicable.

ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.
          -------------------------------------- 

     The legality of the Common Stock and Rights to be issued upon exercise of
the options granted or to be granted under the 1994 Non-Qualified Stock Option
Plan for Non-Employee Directors will be passed upon for the Company by Brown,
Rudnick, Freed & Gesmer, One Financial Center, Boston, Massachusetts 02111.
Donald E. Paulson, Secretary of the Company, is a member of Brown, Rudnick,
Freed & Gesmer. Mr. Paulson and other members and associates of such firm own a
nominal number of shares of Common Stock of the Company.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.
          ----------------------------------------- 

     Section 145 of the General Corporation Law of the State of Delaware
("Section 145") authorizes a corporation to indemnify directors, officers,
employees or agents of the corporation in civil suits if such party acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interest of the corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his or her conduct was
unlawful, as determined in accordance with the Delaware General Corporation Law.
Section 145 requires indemnification if the party in question is successful on
the merits or otherwise. With respect to derivative suits, a person may not be
indemnified if she or he has been adjudged to be liable to the corporation,
unless a court determines that such person is entitled to indemnification.

     Section 145 permits the advancement of advances upon receipt of an
undertaking to repay such amount if it shall ultimately be determined that such
parties are not entitled to be indemnified.

     As permitted under Section 145, the Company's Certificate of Incorporation,
as amended, and By-Laws, as amended, authorize the Company to indemnify
directors and officers against "Expenses" incurred in connection with the
defense or disposition of any "Proceeding" by or in the name of the Company or
any stockholder if the

                                      II-1
<PAGE>
 
director or officer acted in good faith, and in a manner he reasonably believed
to be in, or not opposed to, the best interests of the Company, except that the
Company may not indemnify a director or officer with respect to any matters as
to which such director or officer has been adjudicated liable for negligence or
misconduct in the performance of his duty to the Company, unless, and only to
the extent that, the court deciding the action determines that such a director
or officer is entitled to indemnification. The term "Expenses" is defined in the
Company's By-Laws as liabilities, including but not limited to amounts paid in
satisfaction of judgments, in compromises or as fines or penalties, and
expenses, including reasonable attorneys' and accounting fees. "Proceeding" is
defined to include any threatened, pending, or completed action, suit, or
proceeding, whether civil, criminal, administrative, or investigative, and any
claim which could be the subject of such proceeding.

     The Company's Certificate of Incorporation, as amended, also provides that
a director shall be liable to the extent provided by applicable law (i) for
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the
Delaware General Corporation Law, or (iv) for any transaction from which the
director derived an improper personal benefit. Except as set forth in the
foregoing sentence, however, no director shall be personally liable to the
Company or its stockholders for monetary damages for any breach of fiduciary
duty by such director as a director.

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;

                (iii)   To include any material information with respect to the
                        plan of distribution not previously disclosed in the
                        Registration Statement or any material change in such
                        information in the Registration Statement.

     Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
     Registration Statement is on Form S-3 or Form S-8, 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 Securities Exchange Act of 1934 that are
     incorporated by reference in the Registration Statement.

___________________

    *Not filed herewith. In accordance with Rule 411 promulgated pursuant to the
Securities Act of 1933, as amended, reference is made to the documents
previously filed with the Commission, which are incorporated by reference
herein.

                                      II-3
<PAGE>
 
          (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 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 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.
                                               ---- ----                  

     (h)  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 provisions described under "Item 6--
Indemnification of Directors and Officers" above, 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.

ITEM 4.   DESCRIPTION OF SECURITIES.
          ------------------------- 

     Not applicable.

ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.
          -------------------------------------- 

     The legality of the Common Stock and Rights to be issued upon exercise of
the options granted or to be granted under the 1994 Non-Qualified Stock Option
Plan for Non-Employee Directors will be passed upon for the Company by Brown,
Rudnick, Freed & Gesmer, One Financial Center, Boston, Massachusetts 02111.
Donald E. Paulson, Secretary of the Company, is a member of Brown, Rudnick,
Freed & Gesmer. Mr. Paulson and other members and associates of such firm own a

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.
          ----------------------------------------- 

     Section 145 of the General Corporation Law of the State of Delaware
("Section 145") authorizes a corporation to indemnify directors, officers,
employees or agents of the corporation in civil suits if such party acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interest of the corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his or her conduct was
unlawful, as determined in accordance with the Delaware General Corporation Law.
Section 145 requires indemnification if the party in question is successful on
the merits or otherwise. With respect to derivative suits, a person may not be
indemnified if she or he has been adjudged to be liable to the corporation,
unless a court determines that such person is entitled to indemnification.

     Section 145 permits the advancement of advances upon receipt of an
undertaking to repay such amount if it shall ultimately be determined that such
parties are not entitled to be indemnified.

     As permitted under Section 145, the Company's Certificate of Incorporation,
as amended, and By-Laws, as amended, authorize the Company to indemnify
directors and officers against "Expenses" incurred in connection with the
defense or disposition of any "Proceeding" by or in the name of the Company or
any stockholder if the

                                      II-1
director or officer acted in good faith, and in a manner he reasonably believed
to be in, or not opposed to, the best interests of the Company, except that the
Company may not indemnify a director or officer with respect to any matters as
to which such director or officer has been adjudicated liable for negligence or
misconduct in the performance of his duty to the Company, unless, and only to
the extent that, the court deciding the action determines that such a director
or officer is entitled to indemnification. The term "Expenses" is defined in the
Company's By-Laws as liabilities, including but not limited to amounts paid in
satisfaction of judgments, in compromises or as fines or penalties, and
expenses, including reasonable attorneys' and accounting fees. "Proceeding" is
defined to include any threatened, pending, or completed action, suit, or
proceeding, whether civil, criminal, administrative, or investigative, and any
claim which could be the subject of such proceeding.

     The Company's Certificate of Incorporation, as amended, also provides that
a director shall be liable to the extent provided by applicable law (i) for
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the
Delaware General Corporation Law, or (iv) for any transaction from which the
director derived an improper personal benefit. Except as set forth in the
foregoing sentence, however, no director shall be personally liable to the
Company or its stockholders for monetary damages for any breach of fiduciary
duty by such director as a director.

                        Registration Statement or any material change in such
                        information in the Registration Statement.

     Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
     Registration Statement is on Form S-3 or Form S-8, 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 Securities Exchange Act of 1934 that are
     incorporated by reference in the Registration Statement.

                                      II-3
(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 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 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.
                                               ---- ----                  

     (h)  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 provisions described under "Item 6--
Indemnification of Directors and Officers" above, 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.
