Item 4. DESCRIPTION OF SECURITIES.

     Not Applicable.


Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not Applicable.


Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


        Section 67 of the Massachusetts Business Corporation Law ("MBCL")
provides that a corporation may indemnify its directors, officers, employees and
other agents, and persons who serve at its request as directors, officers,
employees or other agents of another organization or who may serve at its
request in any capacity with respect to any employee benefit plan, to the extent
specified in or authorized by (i) its 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.

        The Company's Restated Articles of Organization, as amended (the
"Charter"), provide that each officer and director of the Company shall be
indemnified by the Company against all expenses incurred by such person in
connection with each proceeding in which such person is involved as a result of
such person's service as an officer or director of the Company or, at the
request of the Company, as a director, officer, employee or agent of any other
organization. No indemnification shall be provided to an officer or director
with respect to a matter as to which it shall have been adjudicated in any
proceeding that such person did not act in good faith in the reasonable belief
that his or her action was in the best interests of the Company. In the event
that a proceeding is compromised or settled so as to impose any liability or
obligation upon an officer or director or upon the Company, no indemnification
shall be provided to such officer or director with respect to a matter if the
Company has obtained an opinion of counsel that with respect to such matter the
officer or director did not act in good faith in the reasonable belief that his
or her action was in the best interests of the Company. To the extent authorized
by the Board of Directors or the stockholders, the Company may advance expenses
prior to the final disposition of a proceeding, upon receipt of an undertaking
by the officer or director to repay the amount of such indemnification if it
shall be established that such person is not entitled to indemnification by an
adjudication or by an opinion of counsel as provided above.

        In addition, the Company's Charter provides that the Company's directors
shall not be liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, except that such provisions shall not
eliminate the liability of a director (i) for any 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)

                                      2
<PAGE>   3




for violations of Section 61 or Section 62 relating to liability for
authorizing illegal distributions and liability for certain loans or (iv) for
any transaction from which the director derived an improper personal benefit.

        The Company has obtained a directors' and officers' liability insurance
policy that insures directors and officers of the Company against losses (above
a deductible amount) arising from certain claims made against them by reason of
certain acts done or attempted by such directors or officers, but only if the
Company is required or permitted to indemnify such directors or officers for
such losses under statutory or common law or under provisions of the Company's
Charter or By-Laws.

        The foregoing provisions and agreements may reduce the legal remedies
available to the Company and its stockholders against the Company's directors
and officers.

        See "Item 9, Undertakings" for a description of the Commission's
position regarding such indemnification provisions.


Item 7. EXEMPTION FROM REGISTRATION CLAIMED.

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.

                             (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 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.

<PAGE>   4


                      (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 (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 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.

Securities and Exchange Commission (the "Commission").

        (a)  The Company's Annual Report on Form 10-K for the fiscal year ended
             January 2, 1999;

        (b)  The Company's Quarterly Report on Form 10-Q for the fiscal quarter
             ended April 3, 1999;

        (c)  The Company's Quarterly Report on Form 10-Q for the fiscal quarter
             ended July 3, 1999;

        (d)  The Company's Quarterly Report on Form 10-Q for the fiscal quarter
             ended October 2, 1999; and

        (e)  The Company's Registration Statement on Form 10, filed with the
             Commission on March 22, 1993 (File No. 0-21404) under Section 12
             of the Securities Exchange Act of 1934, as amended (the "Exchange
             Act"), which contains a description of the Company's Common
             Stock.

        In addition, all documents subsequently filed with the Commission by the
Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act,
prior to the filing of a post-effective amendment hereto which indicates that

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.

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not Applicable.

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Section 67 of the Massachusetts Business Corporation Law ("MBCL")
provides that a corporation may indemnify its directors, officers, employees and
other agents, and persons who serve at its request as directors, officers,
employees or other agents of another organization or who may serve at its
request in any capacity with respect to any employee benefit plan, to the extent
specified in or authorized by (i) its 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.

        The Company's Restated Articles of Organization, as amended (the
"Charter"), provide that each officer and director of the Company shall be
indemnified by the Company against all expenses incurred by such person in
connection with each proceeding in which such person is involved as a result of
such person's service as an officer or director of the Company or, at the
request of the Company, as a director, officer, employee or agent of any other
organization. No indemnification shall be provided to an officer or director
with respect to a matter as to which it shall have been adjudicated in any
proceeding that such person did not act in good faith in the reasonable belief
that his or her action was in the best interests of the Company. In the event
that a proceeding is compromised or settled so as to impose any liability or
obligation upon an officer or director or upon the Company, no indemnification
shall be provided to such officer or director with respect to a matter if the
Company has obtained an opinion of counsel that with respect to such matter the
officer or director did not act in good faith in the reasonable belief that his
or her action was in the best interests of the Company. To the extent authorized
by the Board of Directors or the stockholders, the Company may advance expenses
prior to the final disposition of a proceeding, upon receipt of an undertaking
by the officer or director to repay the amount of such indemnification if it
shall be established that such person is not entitled to indemnification by an
adjudication or by an opinion of counsel as provided above.

        In addition, the Company's Charter provides that the Company's directors
shall not be liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, except that such provisions shall not
eliminate the liability of a director (i) for any 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)

                                      2
3

for violations of Section 61 or Section 62 relating to liability for
authorizing illegal distributions and liability for certain loans or (iv) for
any transaction from which the director derived an improper personal benefit.

        The Company has obtained a directors' and officers' liability insurance
policy that insures directors and officers of the Company against losses (above
a deductible amount) arising from certain claims made against them by reason of
certain acts done or attempted by such directors or officers, but only if the
Company is required or permitted to indemnify such directors or officers for
such losses under statutory or common law or under provisions of the Company's
Charter or By-Laws.

        The foregoing provisions and agreements may reduce the legal remedies
available to the Company and its stockholders against the Company's directors
and officers.

        See "Item 9, Undertakings" for a description of the Commission's
position regarding such indemnification provisions.

Item 7. EXEMPTION FROM REGISTRATION CLAIMED.

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.

                             (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 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.

4

                      (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 (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 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.
