ITEM 3:       INCORPORATION  OF DOCUMENTS BY REFERENCE

       The following documents are incorporated by reference in this
Registration Statement:

       (a) the undersigned registrant's Annual Report on Form 10-K for the year
ended July 31, 1997; (b) the registrant's Quarterly Report on Form 10-Q for the
quarter ended January 31, 1998; and (c) the description of the registrant's

ITEM 4:       DESCRIPTION OF SECURITIES

       Not Applicable

ITEM 5:       INTERESTS OF NAMED EXPERTS AND COUNSEL

       Not applicable.

ITEM 6:       INDEMNIFICATION OF DIRECTORS AND OFFICERS

       Chapter 156B of the Massachusetts General Laws, under which the Company
is organized, permits a Massachusetts corporation to adopt a provision in its
Articles of Organization eliminating or limiting the liability of a director to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such liability does not arise from certain
proscribed conduct (including intentional misconduct and breach of duty of
loyalty).

       On December 8, 1987, the stockholders approved an amendment to the
Company's Articles of Organization. The amendment to the Articles of
Organization, which became effective on April 8, 1988, is as follows:

       "No director shall be personally liable to the corporation or any of its
stockholders for monetary damages for any breach of fiduciary duty as a director
not withstanding any provision of law imposing such liability; provided,
however, that this provision shall not eliminate or limit the liability of a
director for (i) any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) 




                                      II-1



<PAGE>   3

authorizing distributions to stockholders in violation of the corporation's
Articles of Organization or which render the corporation insolvent or bankrupt,
and approving loans to officers or directors of the corporation which are not
repaid and which were not approved or ratified by a majority of disinterested
directors or stockholders, or (iv) any transaction from which the director
derived an improper personal benefit. No amendment to or repeal of this
provision shall apply to or have any effect on the liability or alleged
liability of any director of the corporation for or with respect to any acts or
omissions of such director occurring prior to the effective date of such
amendment."

       The By-laws of the registrant provide for indemnification of officers and
directors as follows:

       Section 6.5  Indemnification.

       (a) The Corporation shall indemnify each director and officer against all
judgments, fines, settlement payments and expenses, including reasonable
attorneys' fees, paid or incurred in connection with any claim, action, suit or
proceeding, civil or criminal, to which he may be made a party or with which he
may be threatened by reason of his being or having been a director or officer of
the Corporation, or, at its request, a director, officer, stockholder or member
of any other corporation, firm, association or other organization or by reason
of his serving or having served, at its request, in any capacity with respect to
any employee benefit plan, or by reason of any action or omission by him in such
capacity, whether or not he continues to be a director or officer at the time of
incurring such expenses or at the time the indemnification is made. No
indemnification shall be made hereunder (i) with respect to payments and
expenses incurred in relation to matters as to which he shall be finally
adjudged in such action, suit or proceeding not to have acted in good faith and
in the reasonable belief that his action was in the best interests of the
Corporation (or, to the extent that such matter relates to service with respect
to an employee benefit plan, in the best interest of the participants or
beneficiaries of such employee benefit plan), or (ii) otherwise prohibited by
law. The foregoing right of indemnification shall not be exclusive of other
rights to which any director or officer may otherwise be entitled and shall
inure to the benefit of the executor or administrator of such director or
officer. The Corporation may pay the expenses incurred by any such person in
defending a civil or criminal action, suit or proceeding in advance of the final
disposition of such action, suit or proceeding, upon receipt of an undertaking
by such person to repay such payment if it is determined that such person is not
entitled to indemnification hereunder.

       (b) The Board of Directors may, without stockholder approval, authorize
the Corporation to enter into agreements, including any amendments or
modification thereto, with any of its directors, officers or other persons
described in paragraph (a) above providing for indemnification of such persons
to the maximum extent permitted under applicable law and the Corporation's
Articles of Organization and By-laws.

       (c) No amendment to or repeal of this section shall have any adverse
effect on (i) the right of any director or officer under any agreement entered
into prior thereto, or (ii) the rights of any director or officer hereunder
relating to his 




                                      II-2


<PAGE>   4

service, for which he would otherwise be entitled to indemnity hereunder, during
any period prior to such amendment or repeal.

       The Company has a directors and officers liability policy that insures
the Company's directors and officers against certain liabilities which they may
incur as directors or officers of the Company.

ended January 31, 1998 and incorporated herein by reference.)

       (5)    Opinion and Consent of Joseph A. Hedal as to the legality of the
securities being registered.

       (23)(A)   Consent of Arthur Andersen LLP

       (23)(B)   Consent of Joseph A. Hedal - included in Exhibit 5.

       (24)   Power of Attorney (contained on the signature page).

ITEM 9:  UNDERTAKINGS

       1.     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 herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

       2.     The undersigned registrant hereby undertakes:

              (a)   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;



                                      II-3


<PAGE>   5

                    (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) (i) and (a) (ii) do not
apply if 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 herein.

              (b)   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 herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

              (c)   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.

       3.     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 of 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

       Not applicable.

ITEM 6:       INDEMNIFICATION OF DIRECTORS AND OFFICERS

       Chapter 156B of the Massachusetts General Laws, under which the Company
is organized, permits a Massachusetts corporation to adopt a provision in its
Articles of Organization eliminating or limiting the liability of a director to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such liability does not arise from certain
proscribed conduct (including intentional misconduct and breach of duty of
loyalty).

       On December 8, 1987, the stockholders approved an amendment to the
Company's Articles of Organization. The amendment to the Articles of
Organization, which became effective on April 8, 1988, is as follows:

       "No director shall be personally liable to the corporation or any of its
stockholders for monetary damages for any breach of fiduciary duty as a director
not withstanding any provision of law imposing such liability; provided,
however, that this provision shall not eliminate or limit the liability of a
director for (i) any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) 

                                      II-1
3

authorizing distributions to stockholders in violation of the corporation's
Articles of Organization or which render the corporation insolvent or bankrupt,
and approving loans to officers or directors of the corporation which are not
repaid and which were not approved or ratified by a majority of disinterested
directors or stockholders, or (iv) any transaction from which the director
derived an improper personal benefit. No amendment to or repeal of this
provision shall apply to or have any effect on the liability or alleged
liability of any director of the corporation for or with respect to any acts or
omissions of such director occurring prior to the effective date of such
amendment."

       The By-laws of the registrant provide for indemnification of officers and
directors as follows:

       Section 6.5  Indemnification.

       (a) The Corporation shall indemnify each director and officer against all
judgments, fines, settlement payments and expenses, including reasonable
attorneys' fees, paid or incurred in connection with any claim, action, suit or
proceeding, civil or criminal, to which he may be made a party or with which he
may be threatened by reason of his being or having been a director or officer of
the Corporation, or, at its request, a director, officer, stockholder or member
of any other corporation, firm, association or other organization or by reason
of his serving or having served, at its request, in any capacity with respect to
any employee benefit plan, or by reason of any action or omission by him in such
capacity, whether or not he continues to be a director or officer at the time of
incurring such expenses or at the time the indemnification is made. No
indemnification shall be made hereunder (i) with respect to payments and
expenses incurred in relation to matters as to which he shall be finally
adjudged in such action, suit or proceeding not to have acted in good faith and
in the reasonable belief that his action was in the best interests of the
Corporation (or, to the extent that such matter relates to service with respect
to an employee benefit plan, in the best interest of the participants or
beneficiaries of such employee benefit plan), or (ii) otherwise prohibited by
law. The foregoing right of indemnification shall not be exclusive of other
rights to which any director or officer may otherwise be entitled and shall
inure to the benefit of the executor or administrator of such director or
officer. The Corporation may pay the expenses incurred by any such person in
defending a civil or criminal action, suit or proceeding in advance of the final
disposition of such action, suit or proceeding, upon receipt of an undertaking
by such person to repay such payment if it is determined that such person is not
entitled to indemnification hereunder.

       (b) The Board of Directors may, without stockholder approval, authorize
the Corporation to enter into agreements, including any amendments or
modification thereto, with any of its directors, officers or other persons
described in paragraph (a) above providing for indemnification of such persons
to the maximum extent permitted under applicable law and the Corporation's
Articles of Organization and By-laws.

       (c) No amendment to or repeal of this section shall have any adverse
effect on (i) the right of any director or officer under any agreement entered
into prior thereto, or (ii) the rights of any director or officer hereunder
relating to his 

                                      II-2
4

service, for which he would otherwise be entitled to indemnity hereunder, during
any period prior to such amendment or repeal.

       The Company has a directors and officers liability policy that insures
the Company's directors and officers against certain liabilities which they may
incur as directors or officers of the Company.

ITEM 9:  UNDERTAKINGS

       1.     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 herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

       2.     The undersigned registrant hereby undertakes:

              (a)   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;

                                      II-3
5

                    (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) (i) and (a) (ii) do not
apply if 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 herein.

              (b)   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 herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

              (c)   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.

       3.     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 of 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.
