     This Rule 13e-3 Transaction Statement (this "Statement") is being filed
with the Securities and Exchange Commission (the "Commission") in connection
with the merger (the "Merger") of ISN Acquisition Corporation ("MergerCo") with
and into Instron Corporation ("Instron"), with Instron continuing as the
surviving corporation (the "Surviving Corporation"), pursuant to an Agreement
and Plan of Merger dated as of May 6, 1999 (the "Merger Agreement") by and among
Instron, MergerCo and Kirtland Capital Partners III L.P., the parent of MergerCo
("Kirtland"). Under the Merger Agreement, each share of common stock, par value
$1.00 per share, of Instron (the "Instron Common Stock") outstanding immediately
prior to the Merger, other than shares held by Instron, its subsidiaries,
MergerCo or dissenting Instron stockholders, will be canceled and converted
automatically into the right to receive $22.00 in cash without interest. In
addition, certain members of Instron's management and their affiliates (the
"Management Investors") and certain members of Instron's Board of Directors
and/or their affiliates (the "Other Investors") who or which are also
stockholders of Instron will exchange some of their shares of Instron Common
Stock for equity in the Surviving Corporation and will have certain of their
stock options assumed by the Surviving Corporation. Accordingly, upon
consummation of the Merger, the entire equity interest in Instron as the
Surviving Corporation will be owned by Kirtland and certain of its affiliates,
the Management Investors and the Other Investors. James M. McConnell, Joseph E.
Amaral, Kenneth L. Andersen, John R. Barrett, Jonathan L. Burr, The Jonathan L.
Burr Trust -- 1965, Yahya Gharagozlou, Arthur D. Hindman, William J. Milliken,
Linton A. Moulding, Jane Elizabeth Moulding and Norman L. Smith are the
Management Investors. George S. Burr, Helen L. Burr and The Harold Hindman
Trust -- 1969 are the Other Investors. Harold Hindman is filing this Statement
solely in his capacity as trustee of The Harold Hindman Trust -- 1969. He is
not, in his individual capacity, one of the Other Investors.


     Concurrently with the filing of this Statement, Instron has filed with the
Commission a preliminary Proxy Statement on Schedule 14A (the "Proxy Statement")
in connection with a special meeting of the stockholders of Instron at which
such stockholders will be asked to approve the Merger Agreement and the
transactions contemplated thereby, including the Merger.

DESPITE PARACHUTE'S EXCELLENT MARKET POSITION AND SIGNIFICANT STRENGTHS, THE
OUTLOOK FOR ORGANIC REVENUE GROWTH IS MODEST

PARACHUTE'S SIGNIFICANT CHARACTERISTICS

- -        Strong market leadership positions worldwide

- -        Engineering/manufacturing and global distribution strengths enable
         successful acquisition strategy

- -        Modest historical and projected revenue growth

- -        Potential revenue volatility and weak, but improving margins in IST
         structural testing business

INDUSTRY OUTLOOK/CONSIDERATIONS

- -        Solid industry demand drivers - Total Quality Management, product
         standardization, new materials/applications

- -        Significant consolidation opportunities

- -        Mature, low growth industry

- -        Some sensitivity to capital goods cycle and recessions

POTENTIAL RECAPITALIZATION RETURNS ANALYSIS

/ /      Financial buyers will base their final purchase prices primarily on
         what they can prudently finance and still generate target equity
         returns of 25-30%

/ /      Belief in management's cash flow projections and potential for cash
         flow growth are critical to achieving required returns

/ /      The prudent use of leverage can increase returns at higher purchase
         prices

/ /      In today's financing markets, a Parachute recapitalization would likely
         be financed with total senior and subordinated debt of up to 4.75x
         EBITDA (pro forma for any "proven" cost savings or unusual items). This
         will result in the following equity returns, based on a range of
         purchase prices and exit multiples:

BACKGROUND ON LEVERAGED RECAPITALIZATIONS                    HIGHLY CONFIDENTIAL

SUMMARY DESCRIPTION OF A RECAPITALIZATION TRANSACTION

/ /      In a recapitalization transaction, a new investor group buys newly
         issued shares from Parachute for cash

/ /      Simultaneously, Parachute borrows new debt financing and uses the
         combined equity and debt proceeds to repurchase enough shares from the
         public (all) and the insiders such that the new investor group is now
         the majority owner, but the existing shareholders still retain at least
         a 10% interest in the post-recapitalization Company (which translates
         into less than 5% of the current Company)

/ /      Since the existing shareholders still hold a significant minority
         interest in Parachute, the SEC does not view the company as being
         "substantially wholly owned" by the new investor group and, therefore,
         does not require "push down" accounting (where, because the acquirer's
         purchase price of Parachute is substantially above the net asset value,
         goodwill is created)

/ /      Thus, purchase accounting at the Parachute level is avoided and no
         goodwill is created on Parachute's financial statements

/ /      While goodwill is recognized at the financial investor level and
         Parachute will likely have negative book value due to the significant
         share repurchase at that level, there are no additional goodwill
         amortization charges at the Parachute level, which can be a significant
         advantage in reporting earnings if the exit strategy is an IPO

         broader group of employees) to align the incentives of the new owners
         and management

/ /      The investor group having voting control of the Company and being

                              INSTRON CORPORATION

                               100 Royall Street
                          Canton, Massachusetts 02021


                                 July 15, 1999


Dear Stockholders:


     You are cordially invited to attend a Special Meeting of Stockholders (the
"Special Meeting") of Instron Corporation, a Massachusetts corporation
("Instron"), to be held on August 17, 1999, at 10:00 a.m., local time, at the
Hilton Dedham Place, 25 Allied Drive, Dedham, Massachusetts 02026. At the
Special Meeting, you will be asked to consider and vote upon the merger (the
"Merger") of ISN Acquisition Corporation, a newly formed Massachusetts
corporation, with and into Instron, pursuant to an Agreement and Plan of Merger
dated as of May 6, 1999 (the "Merger Agreement"). If the Merger is approved and
subsequently consummated, each outstanding share of Instron common stock held by
the public stockholders of Instron will be canceled and converted automatically
into the right to receive $22.00 in cash, without interest.


     ISN Acquisition Corporation was organized by Kirtland Capital Partners III
L.P., a private investment partnership, for the purpose of acquiring all of the
shares of Instron common stock held by the public stockholders of Instron. As a
result of the Merger, Instron will become a privately held company owned by
Kirtland Capital Partners III L.P., certain members of Instron's management and
certain other stockholders of Instron.

     A Special Committee of the Board of Directors of Instron, consisting of
three independent directors, was formed to consider and evaluate the Merger. The
Special Committee has unanimously recommended to Instron's Board of Directors
that the Merger Agreement and the transactions contemplated thereby (the
"Transactions"), including the Merger, be approved. In connection with its
evaluation of the Merger, Instron's Board of Directors engaged The Beacon Group
Capital Services, LLC ("The Beacon Group") to act as its financial advisor and
to advise the Special Committee and the Board of Directors. The Beacon Group has
rendered its opinion dated as of May 6, 1999 to the effect that, as of the date
thereof and based upon and subject to the assumptions, limitations and
qualifications set forth in such opinion, the cash merger consideration of
$22.00 per share was fair from a financial point of view to the public
stockholders of Instron. The written opinion of The Beacon Group is attached as
Appendix B to the enclosed Proxy Statement and should be read carefully and in
its entirety by stockholders.

     INSTRON'S BOARD OF DIRECTORS, BASED ON THE RECOMMENDATION OF THE SPECIAL
COMMITTEE, HAS APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS AND DETERMINED
THAT THE TERMS OF THE MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE
STOCKHOLDERS OF INSTRON. INSTRON'S BOARD OF DIRECTORS RECOMMENDS THAT THE
STOCKHOLDERS VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT AND THE TRANSACTIONS.

     Approval of the Merger Agreement and the Transactions at the Special
Meeting requires the affirmative vote of holders of two-thirds of the
outstanding shares of Instron common stock entitled to vote at the Special
Meeting. Certain current stockholders of Instron, members of Instron's
management and certain of their respective affiliates have agreed, among other
things, to vote their shares of Instron common stock entitled to vote at the
Special Meeting (approximately 22.4% of the outstanding shares of Instron common
stock) in favor of the proposal to approve the Merger Agreement and the
Transactions.

     The accompanying Proxy Statement provides you with a summary of the Merger
and additional information about the parties involved and their interests. If
the Merger is approved by the requisite holders of Instron common stock, the
closing of the Merger will occur as soon after the Special Meeting as all of the
other conditions to closing the Merger are satisfied.

     PLEASE GIVE ALL THIS INFORMATION YOUR CAREFUL ATTENTION. WHETHER OR NOT YOU
PLAN TO ATTEND, IT IS IMPORTANT THAT YOUR SHARES ARE REPRESENTED AT THE SPECIAL
MEETING. A FAILURE TO VOTE WILL COUNT AS A VOTE AGAINST THE MERGER. ACCORDINGLY,
YOU ARE REQUESTED TO PROMPTLY COMPLETE, SIGN AND DATE THE ENCLOSED PROXY CARD
AND RETURN IT IN THE ENVELOPE PROVIDED, WHETHER OR NOT YOU PLAN TO ATTEND. THIS
WILL NOT PREVENT YOU FROM VOTING YOUR SHARES IN PERSON IF YOU SUBSEQUENTLY
CHOOSE TO ATTEND.

                                      Sincerely,

                                      JAMES M. MCCONNELL

     outstanding at the effective time of the Merger, other than shares held by
     Instron, its subsidiaries, MergerCo, or dissenting stockholders, will be
     canceled and converted automatically into the right to receive $22.00 in
     cash, without interest. A copy of the Merger Agreement is attached as

          (2) To consider and act upon such other matters as may properly come
     before the Special Meeting or any adjournment or postponement thereof.

Transactions, written objection to the Merger Agreement and the Transactions
stating that he or she intends to demand payment for his or her shares if the
Merger Agreement and the Transactions are approved by the Instron stockholders
at the Special Meeting and (ii) whose shares are not voted in favor of the
Merger Agreement and the Transactions has or may have the right to demand in
writing from Instron as the Surviving Corporation of the Merger, within 20 days
after the date of mailing to him or her of notice in writing that such approval
has become effective, payment for his or her shares and an appraisal of the
value thereof. Instron and any such stockholder shall in such cases have the
rights and duties and shall follow the procedure set forth in Sections 85 to 98,

                                  INTRODUCTION


     This Proxy Statement is being furnished to the stockholders of Instron
Corporation, a Massachusetts corporation ("Instron" or the "Company"), in
connection with the solicitation by its Board of Directors (the "Instron Board")
of proxies to be used at a Special Meeting of Stockholders (as it may be
adjourned or postponed from time to time, the "Special Meeting") to be held on
August 17, 1999 at 10:00 a.m., local time, at the Hilton Dedham Place, 25 Allied
Drive, Dedham, Massachusetts 02026. The purpose of the Special Meeting is for
the Instron stockholders to consider and vote upon a proposal to approve an
Agreement and Plan of Merger dated as of May 6, 1999 (the "Merger Agreement")
and the transactions contemplated thereby (the "Transactions"), including the
merger (the "Merger") of ISN Acquisition Corporation ("MergerCo"), a corporation
newly formed by Kirtland Capital Partners III L.P. ("Kirtland"), with and into
Instron with Instron continuing as the surviving corporation (the "Surviving
Corporation"). This Proxy Statement is first being mailed to Instron
stockholders on or about July 15, 1999.


                     QUESTIONS AND ANSWERS ABOUT THE MERGER

     Q: WHAT WILL HAPPEN IN THE MERGER?

     A: Upon consummation of the Merger, MergerCo will be merged with and into
Instron and the holders (the "Public Stockholders") of common stock, par value
$1.00 per share, of Instron (the "Instron Common Stock"), other than those
stockholders who exercise and perfect their appraisal rights, will receive a
cash payment of $22.00 for each of their outstanding shares of Instron Common
Stock. Immediately prior to consummation of the Merger, certain members of the
Instron Board, certain members of Instron's management and certain of their
respective affiliates will exchange a portion of their shares of Instron Common
Stock for shares of Series B Preferred Stock, par value $1.00 per share, of
Instron (the "Series B Preferred Stock"). Under the Merger Agreement, the Series
B Preferred Stock will be exchanged for a like number of shares of common stock,
par value $1.00 per share, of the Surviving Corporation (the "Surviving
Corporation Common Stock"). Accordingly, as a result of the Merger, the Public
Stockholders will receive cash for their shares of Instron Common Stock while
the members of the Instron Board, Instron's management and certain of their
respective affiliates mentioned above will receive cash for a portion of their
shares and a continuing equity interest in the Surviving Corporation for the
remainder of their shares.

     Q: WHO WILL OWN INSTRON AFTER THE MERGER?


     A: After the Merger, Instron will be a privately held company owned by the
following individuals and entities (collectively with MergerCo, the "Investor
Group"), each of which will own the approximate percentage of outstanding shares
of the Surviving Corporation Common Stock listed below, subject to certain
assumptions which are described in the Proxy Statement:


     The Equity Investor

         Kirtland Capital Partners III L.P., an Ohio limited partnership, and
         certain of its investors and its affiliates (who will collectively own
         approximately 87.4% of Instron)



     The Other Investors (who will collectively own approximately 6.2% of
         Instron)


         George S. Burr (2.3%)


         Helen L. Burr (less than 1%)


         The Harold Hindman Trust -- 1969 (3.1%)



     The Management Investors (who will collectively own approximately 6.4% of
         Instron)


         James M. McConnell (3.8%)


         Joseph E. Amaral (less than 1%)


         Kenneth L. Andersen (less than 1%)


                                       (i)
<PAGE>   6


         John R. Barrett (less than 1%)


         Jonathan L. Burr (less than 1%)


         The Jonathan L. Burr Trust -- 1965 (less than 1%)


         Yahya Gharagozlou (less than 1%)


         Arthur D. Hindman (less than 1%)


         William J. Milliken (less than 1%)


         Linton A. Moulding and Jane Elizabeth Moulding, as joint tenants (less
         than 1%)


         Norman L. Smith (less than 1%)


     Q: WHY IS INSTRON BEING ACQUIRED?


     A: Instron is being acquired by the Investor Group because the Instron
Board and the Special Committee of the Instron Board (the "Special Committee")
believe that the Merger is a more desirable alternative than continuing to
operate Instron as a public company. In particular, the Instron Board and the
Special Committee considered the risks of continuing to operate Instron as a
public company and the opportunity to enable the Public Stockholders to achieve
liquidity with respect to their investment in Instron at a price that exceeds
the all time highest market price of the Instron Common Stock. To review the
background and reasons for the Merger in greater detail, see pages 12 through
21.


     Q: WHY WAS THE SPECIAL COMMITTEE FORMED?

     A: The Instron Board established the Special Committee consisting of
independent directors to review and evaluate the proposed transaction. The
Instron Board formed the Special Committee primarily because it believed that a
recapitalization transaction such as the Merger might present potential
conflicts of interest for Instron's senior management and certain members of the
Instron Board, who, unlike the Public Stockholders, would have a continuing
interest in Instron following consummation of such a transaction. The Special
Committee has determined that the Merger is fair to and in the best interests of
the Instron stockholders.

     Q: WHAT WILL I RECEIVE IN THE MERGER?

     A: As a Public Stockholder, you will receive $22.00 in cash, without
interest, for each share of Instron Common Stock that you own. This is the "Cash
Merger Consideration." For example: If you own 100 shares of Instron Common
Stock, upon completion of the Merger you will receive $2,200.00 in cash.

     Q: IF THE MERGER IS CONSUMMATED, WHEN CAN I EXPECT TO RECEIVE THE CASH
MERGER CONSIDERATION FOR MY SHARES?

     A: Promptly after the Merger is consummated, Instron will send you detailed
instructions regarding the surrender of your Instron Common Stock certificates.
You should not send your Instron Common Stock certificates to Instron or anyone
else until you receive these instructions. Instron will send payment of the Cash
Merger Consideration to you as promptly as practicable following its receipt of
your stock certificates and other required documents.

     Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

     A: We expect the Merger to be consummated during the third quarter of 1999.

     Q: WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?


     A: The receipt of the Cash Merger Consideration by you will be a taxable
transaction for federal income tax purposes. To review the tax consequences to
you in greater detail, see page 61. Your tax consequences will depend on your
personal situation. You should consult your tax advisors for a full
understanding of the tax consequences of the Merger to you.


     Q: WHAT AM I BEING ASKED TO VOTE UPON?

     A: You are being asked to approve the Merger Agreement, which provides,
among other things, for the acquisition of Instron by the Investor Group, and
the Transactions. After the Merger, Instron will be a privately held company and
you will no longer own an equity interest in Instron. The Instron Board has
approved the Merger Agreement and the Transactions and recommends that you vote
"For" the approval of the Merger Agreement and the Transactions.

                                      (ii)
<PAGE>   7

     Q: WHAT DO I NEED TO DO NOW?

     A: This Proxy Statement contains important information regarding the Merger
as well as information about Instron and the Investor Group. It also contains
important information about what the management of Instron, the Instron Board
and the Special Committee considered in evaluating the Merger. We urge you to
read this Proxy Statement carefully, including its Appendices. You may also want
to review the documents referenced under "Where You Can Find More Information."

     Q: HOW DO I VOTE?


     A: Just indicate on your proxy card how you want to vote, and sign and mail
it in the enclosed envelope as soon as possible, so that your shares will be
represented at the Special Meeting. Approval of the proposal to approve the
Merger Agreement and the Transactions requires the affirmative vote of holders
of two-thirds of the outstanding shares of Instron Common Stock entitled to vote
at the Special Meeting. Therefore, a failure to vote or a vote to abstain will
have the same effect as a vote against the proposal. The Special Meeting will
take place on August 17, 1999 at 10:00 a.m., local time, at the Hilton Dedham
Place, 25 Allied Drive, Dedham, Massachusetts 02026. You may attend the Special
Meeting and vote your shares in person, rather than voting by proxy. In
addition, you may withdraw your proxy up to and including the day of the Special
Meeting and either change your vote or attend the Special Meeting and vote in
person.


     Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE
MY SHARES FOR ME?

     A: Your broker will vote your shares of Instron Common Stock only if you
provide instructions on how to vote. You should instruct your broker how to vote
your shares, following the directions your broker provides. If you do not
provide instructions to your broker, your shares will not be voted and they will
be counted as votes against the proposal to approve the Merger Agreement and the
Transactions.

     This summary highlights selected information from this document and may not
contain all of the information that is important to you. For a more complete
understanding of the Merger, and for a more complete description of the legal
terms of the Merger, you should read this Proxy Statement in its entirety
carefully, as well as the additional documents to which we refer you, including
the Merger Agreement. See "Where You Can Find More Information" (page 72).


EFFECTS OF THE MERGER

     Pursuant to the Merger Agreement, MergerCo will be merged with and into
Instron with Instron being the Surviving Corporation. As a result of the Merger,
all of the capital stock of Instron will be owned by the Investor Group, and the
Instron Common Stock will no longer be publicly traded. The Public Stockholders
will no longer be stockholders of Instron and they will not participate in
Instron's future earnings and growth or bear the risk of any decreases in the
value of Instron. Instead, the Public Stockholders will have the right to
receive $22.00 in cash, without interest, for each share of Instron Common Stock
held by such stockholders. The Investor Group will have the opportunity to
benefit from any future earnings and growth of Instron and will bear the risk of
any decreases in the value of Instron. In addition, the Other Investors and the
Management Investors have interests in the Merger as directors and/or employees
of Instron or affiliates of directors and/or employees of Instron which are
different from, or in addition to, yours as an Instron stockholder. To review
these interests, see "-- Conflicts of Interest" and "Special
Factors -- Conflicts of Interest."

THE SPECIAL MEETING (page 44)



     The Special Meeting will be held on August 17, 1999, at 10:00 a.m., local
time, at the Hilton Dedham Place, 25 Allied Drive, Dedham, Massachusetts 02026.
At the Special Meeting, the Instron stockholders will be asked to consider and
vote upon a proposal to approve the Merger Agreement and the Transactions.



RECORD DATE; VOTING POWER (page 44)



     Holders of record of Instron Common Stock at the close of business on July
12, 1999 are entitled to notice of and to vote at the Special Meeting. As of
such date, there were 6,978,448 shares of Instron Common Stock issued and
outstanding held by approximately 417 holders of record. Holders of record of
Instron Common Stock on the Record Date are entitled to one vote per share on
any matter that may properly come before the Special Meeting.



VOTE REQUIRED (page 44)


     Approval by the Instron stockholders of the proposal to approve the Merger
Agreement and the Transactions will require the affirmative vote of two-thirds
of the outstanding shares of Instron Common Stock entitled to vote at the
Special Meeting. Accordingly, a failure to vote or a vote to abstain will have
the same legal effect as a vote against the Merger.

     An "Against" vote on the enclosed proxy card will be a vote against the
Merger Agreement and the Transactions. If we do not receive "For" votes from
two-thirds of the outstanding shares of Instron Common Stock entitled to vote at
the Special Meeting, the Merger Agreement and the Transactions will not be
approved, you will not receive $22.00 in cash for each share of Instron Common
Stock you hold and you will continue to own shares in a publicly traded company.

     A stockholder who gives a proxy with respect to voting on the Merger
Agreement and the Transactions may revoke it at any time before it is voted at
the Special Meeting by either (i) filing with the Clerk of Instron an instrument
revoking it, (ii) submitting a duly executed proxy bearing a later date or (iii)
voting in person at the Special Meeting.

     The Other Investors and certain of their affiliates and the Management
Investors and certain of their affiliates have agreed, among other things, to
vote the shares of Instron Common Stock owned by such stockholders
(approximately 22.4% of the outstanding shares of Instron Common Stock) in favor
of the proposal to approve the Merger Agreement and the Transactions.


RECOMMENDATIONS (page 21)


     The Instron Board established the Special Committee to review and evaluate
the proposed transaction. The Instron Board formed the Special Committee
primarily because it believed that a recapitalization transaction such as the
Merger might present potential conflicts of interest for Instron's senior
management and certain members of the Instron Board, who, unlike the Public
Stockholders, would have a continuing interest in Instron following consummation
of such a transaction. The Special Committee unanimously

                                        2
<PAGE>   13

recommended that the Instron Board approve the Merger Agreement and the
Transactions and that the Instron Board recommend that the Instron stockholders
approve the Merger Agreement and the Transactions. Following the unanimous
recommendation of the Special Committee, the Instron Board, other than Harold
Hindman, George S. Burr and James M. McConnell, unanimously determined that the
Merger Agreement and the Transactions, including the Merger, were fair to and in
the best interests of the Instron stockholders and recommended that the
stockholders approve the Merger Agreement and the Transactions. Messrs. Hindman,
Burr and McConnell abstained from voting on the Merger Agreement and the
Transactions because each of them has an interest in the Merger as a member of
the Investor Group. The Special Committee and the Instron Board recommend that
the Instron stockholders vote "For" the approval of the Merger Agreement and the
Transactions. You also should refer to the factors that the Special Committee
and the Instron Board considered in determining whether to approve the Merger
Agreement and the Transactions on pages 19-22.


OPINION OF FINANCIAL ADVISOR (page 26)


     The Beacon Group Capital Services, LLC ("The Beacon Group"), a nationally
recognized investment banking firm that served as financial advisor to the
Instron Board and the Special Committee, has rendered an opinion dated as of May
6, 1999 to the Instron Board that, as of the date of the opinion, and based on
the assumptions and subject to the limitations and qualifications set forth
therein, the Cash Merger Consideration was fair from a financial point of view
to the Public Stockholders. A copy of The Beacon Group's opinion, setting forth
the information reviewed, assumptions made and matters considered by The Beacon
Group, is attached to this Proxy Statement as Appendix B. You should read The
Beacon Group's opinion in its entirety.


TERMS OF THE MERGER AGREEMENT (page 47)


     The Merger Agreement is attached to this Proxy Statement as Appendix A. You
are encouraged to read the Merger Agreement in its entirety. It is the legal
document that governs the Merger.


     General. Upon consummation of the Merger, MergerCo will be merged with and
into Instron and the Public Stockholders will receive a cash payment of $22.00
for each of their outstanding shares of Instron Common Stock. Immediately prior
to the consummation of the Merger, the Other Investors and the Management
Investors will exchange a portion of their shares of Instron Common Stock for
shares of Series B Preferred Stock of Instron. The Merger Agreement provides
that the shares of Series B Preferred Stock will be exchanged for a like number
of shares of Surviving Corporation Common Stock. Accordingly, as a result of the
Merger, the Public Stockholders will receive cash for their shares of Instron
Common Stock while the Other Investors and the Management Investors will receive
cash for a portion of their shares and a continuing equity interest in the
Surviving Corporation for the remainder of their shares.


     Conditions to the Merger. The completion of the Merger depends upon the
satisfaction of certain conditions, including:

     - approval of the Merger Agreement and the Transactions by holders of
       two-thirds of the outstanding shares of Instron Common Stock entitled to
       vote at the Special Meeting;

     - absence of a material adverse change in the business, assets, condition
       (financial or otherwise) or results of operations of Instron and its
       subsidiaries taken as a whole or any event or other circumstance which
       would, individually or in the aggregate, reasonably be expected to result
       in any such material adverse change;

     - absence of a material disruption or material adverse change in the
       banking, financial or capital markets generally or in the market for
       senior credit facilities or for new issuances of high yield securities
       which has caused either of the lenders to Kirtland to withdraw its
       commitment to provide financing as contemplated by such lender's
       financing commitment letter to Kirtland;


     - Instron having no more than $13.0 million of Net Indebtedness as of the
       closing date of the Merger. "Net Indebtedness" is defined under the
       Merger Agreement generally as all obligations of Instron and


                                        3
<PAGE>   14

its subsidiaries for borrowed money or evidenced by a bond, note, debenture or
similar instrument, minus all cash and cash equivalents of Instron and its
subsidiaries;

     - no more than 5% of the outstanding shares of Instron Common Stock having
       taken actions to assert dissenters' rights under Sections 85 to 98,
       inclusive, of the Massachusetts Business Corporation Law (Chapter 156B of
       the General Laws of Massachusetts ) (the "MBCL"); and

     - antitrust regulatory approval and the expiration of applicable waiting
       periods relating thereto.

     Each party may, at its option, waive the satisfaction of any condition to
such party's obligations under the Merger Agreement. EVEN IF THE INSTRON
STOCKHOLDERS APPROVE THE MERGER, THERE CAN BE NO ASSURANCE THAT THE MERGER WILL
BE CONSUMMATED.

     Solicitation. Generally, Instron and its affiliates are prohibited from
initiating or soliciting, and are prohibited from participating in discussions
regarding, any proposal from a third party with respect to a merger,
consolidation, sale, or similar transaction involving Instron. Instron may,
under certain specified circumstances, take certain actions in connection with
unsolicited acquisition proposals.

     Termination. Either Instron or MergerCo may terminate the Merger Agreement
under certain circumstances, including if:

     - both parties consent in writing;

     - the Instron stockholders do not approve the Merger Agreement;

     - legal restraints or prohibitions prevent the consummation of the Merger;
       or

     - the other party breaches any of its representations, warranties or
       covenants under the Merger Agreement and fails to timely cure any such
       breach.

     In addition, Instron generally may terminate the Merger Agreement if it
enters into a definitive agreement to effect another acquisition transaction
that is more favorable to the Instron stockholders from a financial point of
view than the Transactions (a "Superior Proposal"). Instron may also terminate
the Merger Agreement after 60 days following its receipt of a notice from
Kirtland that a lender to Kirtland has indicated to either Kirtland or MergerCo
that such lender will be unable to provide the financing contemplated by its
financing commitment letter to Kirtland (a "Kirtland Financing Notice").
MergerCo may terminate the Merger Agreement if the Instron Board withdraws,
modifies, or changes its approval or recommendation of the Transactions in a
manner material and adverse to MergerCo, or proposes or announces any intention
to enter into any agreement with respect to another acquisition transaction.
MergerCo also may terminate the Merger Agreement after 60 days following
delivery by Kirtland or MergerCo of a Kirtland Financing Notice.


     Fees and Expenses. Generally, Instron, on the one hand, and Kirtland and
MergerCo, on the other hand, will pay their own fees, costs, and expenses
incurred in connection with the Merger Agreement and the Transactions. However,
Instron will pay MergerCo "liquidated damages" in an amount equal to $5.0
million plus an amount equal to the reasonable out-of-pocket costs and expenses
incurred by Kirtland and MergerCo in connection with the Merger Agreement and
the Transactions (not to exceed $1.0 million) under certain circumstances,
including if:


     - MergerCo terminates the Merger Agreement as a result of Instron having
       wilfully breached its obligation to call a special meeting of
       stockholders or to take certain actions with respect to the preparation
       of this Proxy Statement;

     - Instron terminates the Merger Agreement in connection with entering into
       a definitive agreement to effect a Superior Proposal;

     - MergerCo terminates the Merger Agreement because of a material and
       adverse withdrawal, modification or change in the approval or
       recommendation of the Instron Board of the Merger Agreement or the
       Transactions; or

                                        4
<PAGE>   15

     - Either Instron or MergerCo terminates the Merger Agreement because the
       Instron stockholders shall have failed to approve the Merger Agreement
       and, within nine months of such termination, Instron enters into a
       definitive agreement with respect to another acquisition transaction with
       a person or an affiliate thereof who had made a proposal for an
       acquisition transaction directly to the Instron stockholders or publicly
       announced such a transaction or solicited proxies or consents in
       opposition to the Merger prior to the Special Meeting.

     Stock Options. Generally, each option to purchase shares of Instron Common
Stock will become fully vested and exercisable immediately prior to the Merger.
Holders of options outstanding immediately prior to the Effective Time, except
for certain options which will be assumed by the Surviving Corporation in the
Merger, will receive cash for such options based on the number of shares of
Instron Common Stock underlying the options to be cashed out and the difference
between the applicable per share exercise price of such options and the Cash
Merger Consideration.


SHARE OWNERSHIP OF INSTRON FOLLOWING THE MERGER (page 35)



     The Equity Investor. The exact amount of the Equity Investor's investment
in MergerCo is dependent upon the level of Net Indebtedness of Instron as of the
Effective Time of the Merger. At April 3, 1999, Instron's Net Indebtedness was
approximately $3.9 million. If Instron's Net Indebtedness at the Effective Time
is greater or less than $3.9 million, then the Equity Investor will be required
to increase or decrease, respectively, its investment in MergerCo and therefore
the Surviving Corporation. Accordingly, all of the references to the Equity
Investor's investment, number of shares of Surviving Corporation Common Stock
and ownership percentage, as well as the ownership percentages of all other
stockholders in the Surviving Corporation, are dependent upon the level of
Instron's Net Indebtedness as of the closing Effective Time. For purposes of
this Proxy Statement the level of Instron's Net Indebtedness as of the Effective
Time is assumed to be $3.9 million. Accordingly, prior to the Merger the Equity
Investor will contribute approximately $49.6 million in cash to MergerCo in
exchange for approximately 450,545 shares of common stock of MergerCo, which
shares will be converted into a like number of shares of Surviving Corporation
Common Stock in the Merger. Upon consummation of the Transactions, the Equity
Investor will own approximately 87.4% of the outstanding shares of Surviving
Corporation Common Stock. See "Unaudited Pro Forma Condensed Consolidated
Financial Data."



     The Other Investors. To permit the Other Investors to receive shares of
Surviving Corporation Common Stock rather than the Cash Merger Consideration in
the Merger, the Other Investors will exchange immediately prior to the Merger an
aggregate of 160,000 shares of Instron Common Stock for an aggregate of 32,000
shares of Series B Preferred Stock of Instron. These shares of Series B
Preferred Stock will be converted into a like number of shares of Surviving
Corporation Common Stock in the Merger. The 1-for-5 exchange ratio for the
exchange of Instron Common Stock for Series B Preferred Stock was agreed to by
the Other Investors, the Management Investors and Kirtland so that the
percentage ownership of each of the members of the Investor Group in the
Surviving Corporation will reflect their relative contributions of equity to the
Surviving Corporation and to reduce the total number of outstanding shares in
the Surviving Corporation. The fair value of the shares of Instron Common Stock
to be exchanged for shares of Series B Preferred Stock is equal to the fair
value of the shares of Series B Preferred Stock. Upon consummation of the
Transactions, the Other Investors will own approximately 6.2% of the outstanding
shares of Surviving Corporation Common Stock.



     The Management Investors. To permit the Management Investors to receive
shares of Surviving Corporation Common Stock rather than the Cash Merger
Consideration in the Merger, the Management Investors will exchange immediately
prior to the Merger an aggregate of 165,210 shares of Instron Common Stock
(including an aggregate of 25,340 shares of restricted Instron Common Stock
previously issued under the Instron Corporation 1992 Stock Incentive Plan, as
amended) for an aggregate of 33,042 shares of Series B Preferred Stock. These
shares of Series B Preferred Stock will be converted into a like number of
shares of Surviving Corporation Common Stock in the Merger. The 1-for-5 exchange
ratio for the exchange of Instron Common Stock for Series B Preferred Stock was
agreed to by the Other Investors, the Management Investors


                                        5
<PAGE>   16


and Kirtland so that the percentage ownership of each of the members of the
Investor Group in the Surviving Corporation will reflect their relative
contributions of equity to the Surviving Corporation and to reduce the total
number of outstanding shares in the Surviving Corporation. The fair value of the
shares of Instron Common Stock to be exchanged for shares of Series B Preferred
Stock is equal to the fair value of the shares of Series B Preferred Stock. Upon
consummation of the Transactions, the Management Investors will own
approximately 6.4% of the outstanding shares of Surviving Corporation Common
Stock. In addition, options to purchase up to an aggregate of 125,000 shares of
Instron Common Stock held by certain Management Investors will be assumed by the
Surviving Corporation and converted into options (the "Rollover Options") to
purchase up to an aggregate of 25,000 shares of Surviving Corporation Common
Stock representing in the aggregate approximately 4.6% of the Surviving
Corporation Common Stock on a fully diluted basis (assuming the exercise of all
such options). These options will be fully vested and immediately exercisable
upon consummation of the Merger. In addition, it is anticipated that the
Surviving Corporation, upon consummation of the Merger and pursuant to a stock
option plan to be adopted by the Surviving Corporation at that time, will grant
options to purchase up to an aggregate of approximately 24,000 shares of
Surviving Corporation Common Stock to the Management Investors, representing in
the aggregate approximately 4.3% of the Surviving Corporation Common Stock on a
fully diluted basis (assuming the exercise of all options, including the
Rollover Options).


ACCOUNTING TREATMENT

     Instron believes that the Merger and the other Transactions will be
accounted for as a recapitalization for accounting purposes. Under the
recapitalization method of accounting, the historical cost basis of Instron's
assets and liabilities will be carried forward to the Surviving Corporation with
the aggregate cost of repurchasing the Instron Common Stock accounted for as a
reduction to stockholders' equity. Accordingly, the historical basis of
Instron's assets and liabilities will not be affected by the Merger and the
other Transactions.


FINANCING OF THE MERGER (page 42)


     The total amount of funds necessary to consummate the Transactions is
expected to be approximately $174.2 million. These funds are expected to come
from the following sources:

     - an equity investment made by the Equity Investor of approximately $49.6
       million, assuming a Net Indebtedness of $3.9 million;

     - borrowings by the Surviving Corporation of approximately $14.0 million
       under a new credit facility;

     - borrowings by the Surviving Corporation of approximately $100.0 million
       from the issuance of debt instruments; and

     - Instron's available cash reserves which, as of April 3, 1999, was
       approximately $10.6 million.

     Kirtland has received from National City Bank a letter dated May 3, 1999
(the "National City Letter") pursuant to which National City Bank has committed
to provide debt financing to Instron under the terms of a $50.0 million
revolving credit facility (the "Credit Facility"), of which approximately $14.0
million will be used to finance the consummation of the Transactions. In
addition, Kirtland currently anticipates that it will raise $100.0 million of
the funds necessary to consummate the Transactions through the issuance of debt
instruments in the private or public capital markets. However, in the event that
Kirtland is unable to obtain such debt financing, Kirtland has entered into a
letter agreement (the "DLJ Bridge Letter" and, together with the National City
Letter, the "Financing Letters") dated May 4, 1999, with DLJ Bridge Finance,
Inc. ("DLJ Bridge"), pursuant to which DLJ Bridge has committed to purchase from
Instron $100.0 million in principal amount of unsecured senior subordinated
increasing rate notes (the "Bridge Notes"). The Financing Letters are subject to
the satisfaction of various conditions, including the condition that no material
adverse change in the business, assets, condition (financial or otherwise) or
results of operations of Instron and its subsidiaries taken as a whole shall
have occurred and that there shall not have occurred any event or other
circumstance

                                        6
<PAGE>   17

which would, individually or in the aggregate, reasonably be expected to result
in any such material adverse change prior to the Effective Time.


CONFLICTS OF INTEREST (page 34)


     The Other Investors. The Other Investors have interests in the Merger as
directors of Instron or affiliates of directors of Instron that are different
from, or in addition to, yours as a stockholder of Instron. In the Merger, a
portion of the shares of Instron Common Stock held by the Other Investors will
ultimately be converted into shares of Surviving Corporation Common Stock.
Accordingly, the Other Investors will continue to have an equity interest in
Instron after the Merger and the ultimate value of this interest could be more
or less than the $22.00 per share to be received by the Public Stockholders in
the Merger. In addition, a majority of the shares of Instron Common Stock held
by the Other Investors and certain of their affiliates will not be converted
into shares of Surviving Corporation Common Stock but will be converted in the
Merger into the right to receive the Cash Merger Consideration in the aggregate
amount of approximately $15.9 million.

     The Management Investors. The Management Investors have interests in the
Merger as employees and/or directors of Instron or affiliates of such employees
and/or directors that are different from, or in addition to, yours as a
stockholder of Instron. In the Merger, a portion of the shares of Instron Common
Stock held by the Management Investors will ultimately be converted into shares
of Surviving Corporation Common Stock and certain options to purchase Instron
Common Stock held by the Management Investors will be assumed by the Surviving
Corporation and converted into the Rollover Options. Furthermore, the Surviving
Corporation will grant additional options to certain Management Investors.
Accordingly, the Management Investors will continue to have an equity interest
in Instron after the Merger and the ultimate value of this interest could be
more or less than the $22.00 per share to be received by the Public Stockholders
in the Merger. In addition, a majority of the shares of Instron Common Stock and
options held by the Management Investors will not be converted into shares of
Surviving Corporation Common Stock or assumed by the Surviving Corporation, as
the case may be, but will be converted in the Merger into the right to receive
the Cash Merger Consideration and the right to receive cash for such options,
respectively, in the aggregate amount of approximately $14.9 million.

     If the Merger is consummated, it is expected that those Management
Investors who were members of Instron's management prior to the Merger will
continue as members of management of the Surviving Corporation.

     Other Agreements. Upon consummation of the Merger, the Surviving
Corporation and all of the stockholders of the Surviving Corporation, including
the Other Investors and the Management Investors, will enter into a stockholders
agreement (the "Stockholders Agreement") that will, among other things, restrict
their transfer of shares of Surviving Corporation Common Stock. The Other
Investors, the Management Investors and the Surviving Corporation also will
enter into a registration rights agreement (the "Registration Rights Agreement")
pursuant to which the Other Investors and the Management Investors will have
certain registration rights with respect to their shares of Surviving
Corporation Common Stock. Also, certain indemnification arrangements and
directors' and officers' liability insurance for existing directors and officers
of Instron will be continued by the Surviving Corporation after the Merger.

     The Beacon Group. The Beacon Group served as financial advisor to the
Instron Board and the Special Committee. Two managing directors of The Beacon
Group are limited partner investors in Kirtland. The Instron Board, the Special
Committee and The Beacon Group believe that the foregoing relationships do not
affect The Beacon Group's ability to act independently and impartially as
financial advisor to the Instron Board and the Special Committee.

     The Special Committee. The members of the Special Committee will be treated
in the Merger as Public Stockholders with respect to their shares of Instron
Common Stock. Members of the Special Committee will have the right to receive
Cash Merger Consideration in the aggregate amount of $605,000 for their shares
of Instron Common Stock. The three members of the Special Committee also
received an aggregate of $30,500
                                        7
<PAGE>   18

from Instron as compensation for serving on the Special Committee. The Instron
Board and the Special Committee believe that the foregoing arrangements do not
affect the Special Committee's independence or impartiality.


REGULATORY APPROVALS (page 55)



     Instron is required to make filings with or obtain approvals from certain
United States antitrust regulatory authorities in connection with the Merger.
These consents and approvals include the approval of the United States Federal
Trade Commission and the Department of Justice. An application and notice was
filed with the Federal Trade Commission and the Department of Justice and the
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, expired on June 21, 1999.



APPRAISAL RIGHTS (page 54)


     Any Instron stockholder has the right to dissent from approval of the
Merger Agreement and, subject to strict compliance with certain requirements and
procedures set forth in Sections 85 to 98, inclusive, of the MBCL, to receive
payment of the "fair value," as defined in the MBCL, of his or her shares of
Instron Common Stock. To perfect these appraisal rights with respect to the
Merger, you must follow the required procedures precisely. The full text of
Sections 85 to 98, inclusive, of the MBCL is attached to this Proxy Statement as
Appendix C.


FEDERAL INCOME TAX CONSEQUENCES (page 61)



     Generally, the receipt of the Cash Merger Consideration in the Merger by
Public Stockholders will be a taxable transaction for federal income tax
purposes. Each holder's gain or loss per share of Instron Common Stock will be
equal to the difference between $22.00 and the holder's adjusted basis in that
particular share of the Instron Common Stock. Such gain or loss generally will
be a capital gain or loss. The federal income tax rule applicable to any gain
will generally depend on the length of time that such shares of Instron Common
Stock were held by the holder. Because the tax consequences to each holder of
Instron Common Stock will depend on each holder's particular circumstances and
tax position, you should consult your tax advisors as to the specific tax
consequences of the Merger to you.

         EBITDA differently than Instron. EBITDA is not a measurement of
         financial performance under generally accepted accounting principles
         and should not be considered as an alternative to cash flow from
         operating activities or as a measure of liquidity or as an alternative
         to net income as indicators of Instron's operating performance or any
         other measure of performance derived in accordance with generally
         accepted accounting principles. See the Statement of Cash Flow included

                                SPECIAL FACTORS

BACKGROUND OF THE MERGER


     During the first quarter of calendar 1998, management and the Instron Board
began to actively consider the various alternatives by which Instron might
enhance long-term shareholder value. In connection with its review, management
and the Instron Board noted the limited public trading volume of the Instron
Common Stock on AMEX, as evidenced by the fact that the average monthly trading
volume on AMEX between July 1, 1997 and March 31, 1998 was approximately 138,500
shares. Moreover, they noted that the public float of the Instron Common Stock
had never exceeded $100 million due in part to the significant ownership of
shares held by the executive officers and directors of Instron (approximately
20%). Based on the foregoing, the Instron Board and management believed that the
Instron Common Stock was an illiquid security and that this illiquidity had an
adverse effect on the trading price of the Instron Common Stock. Accordingly, in
the second calendar quarter of 1998, the Instron Board sought to engage a
financial advisor to render advice to the Instron Board concerning options for
Instron stockholders to achieve greater liquidity and other alternatives which
might enhance shareholder value.


     On June 8, 1998, representatives of The Beacon Group met with James M.
McConnell, the Chief Executive Officer and President of Instron, and Linton A.
Moulding, the Chief Financial Officer of Instron, and discussed in general terms
various alternatives pursuant to which Instron might enhance shareholder value
and create options for increasing stockholder liquidity. The alternatives
outlined by The Beacon Group included (i) acquiring strategic businesses or
assets that would add to or strengthen Instron's core businesses, (ii) divesting
or spinning off certain of Instron's non-core businesses, (iii) entering into
joint ventures and strategic alliances and (iv) a potential sale of Instron. The
Beacon Group also reviewed with Messrs. McConnell and Moulding the processes
involved if the company were to pursue the various alternatives and the
advisability and feasibility of pursuing a particular alternative. In addition
to meeting with The Beacon Group, Messrs. McConnell and Moulding met with other
investment banking firms in June 1998 to assess the desirability of engaging a
particular firm to assist the Instron Board in evaluating strategic
alternatives.

     On June 30, 1998, the Executive Committee of the Instron Board (the
"Executive Committee"), which consisted of Mr. McConnell, Harold Hindman, the
Chairman of the Instron Board, and Richard W. Young, met to review and discuss
proposals from the three investment banking firms with whom Messrs. McConnell
and Moulding had met. At this meeting, the Executive Committee recommended that
the Instron Board retain The Beacon Group to assist the Instron Board in
exploring and considering strategic alternatives. Thereafter, on July 10, 1998,
the Instron Board retained The Beacon Group to act as its financial and
strategic advisor.

     On July 13, 1998, representatives of The Beacon Group met with senior
management of Instron, including Messrs. McConnell and Moulding, to discuss the
process by which The Beacon Group would assist the Instron Board in evaluating
strategic alternatives. At this meeting, The Beacon Group indicated that it
would first need to conduct financial and other due diligence concerning Instron
and its business and operations. The representatives of The Beacon Group advised
Instron's management that, following completion of such due diligence, The
Beacon Group would present to the Instron Board an analysis of the strategic
alternatives available to Instron and The Beacon Group's assessment of the
alternative or alternatives that were most likely to enhance shareholder value
and provide stockholders with increased liquidity.


     On August 11, 1998, the Instron Board held a meeting at which
representatives of The Beacon Group advised the Instron Board with respect to a
range of strategic alternatives that might be available to Instron to enhance
shareholder value and provide stockholders with greater liquidity. These
alternatives included, among other things, (i) remaining an independent company
and continuing to pursue Instron's operating and business strategy, which
included the acquisition of strategic businesses or assets that would add to or
strengthen Instron's core businesses, (ii) divesting Instron's non-core
businesses through asset sales or spin-off transactions, (iii) undertaking a
share repurchase program, (iv) entering into joint ventures and other strategic
alliances and (v) selling the Company. The Beacon Group described certain
criteria used by it to evaluate these strategic alternatives, which included,
among others: preliminary indications of the value that might be received by
Instron stockholders based on various analyses (including an analysis of
comparable companies,


                                       12
<PAGE>   23


an analysis of comparable mergers and acquisitions transactions, various
discounted cash flow analyses and a leveraged recapitalization analysis); the
ability of Instron to sustain growth given its current assets, size and market
capitalization; the stability of Instron's income stream; the liquidity
available to Instron stockholders from various strategic alternatives; and the
certainty of and risks involved in consummating various potential transactions.



     Following the presentation by The Beacon Group, the Instron Board engaged
in a discussion concerning the various alternatives. The Instron Board concluded
that because Instron's non-core businesses were small and their divestiture
would be unlikely to have a material effect on Instron's market value,
divestitures of non-core businesses was not an alternative likely to enhance
shareholder value or provide liquidity to the Instron stockholders. The Instron
Board likewise concluded that spin-offs of non-core businesses would not be a
viable alternative because none of Instron's non-core businesses were large
enough to be stand-alone public companies. With respect to joint ventures, the
Instron Board determined that within the materials and structural testing
systems industry the opportunities for joint ventures and other strategic
alliances were limited. The Instron Board concluded that a share repurchase
program was not an attractive alternative because it would only exacerbate the
illiquidity of the Instron Common Stock.


     In reviewing potential alternatives at the August 11, 1998 Instron Board
meeting, the Instron Board noted that while acquiring strategic businesses or
assets that could add to or strengthen Instron's core businesses would not
address stockholder liquidity concerns, Instron had been successful to date in
executing that operating and business strategy. The Instron Board discussed the
fact that it could continue to focus on add-on acquisitions where it could
leverage its market position to reduce costs and increase efficiency. However,
the Instron Board believed that in view of the markets in which the company
operated, in the future there would likely be fewer attractive acquisition
candidates and that enhancing shareholder value by maintaining the status quo
and pursuing add-on acquisitions was inherently risky. The Instron Board also
discussed the strategy of engaging in a sizable acquisition, which it believed
had the potential, among other things, to diversify Instron's revenue mix,
leverage and strengthen its distribution network with broader product offerings
and increase revenue and cash flow. However, the Instron Board believed that
undertaking such a significant acquisition would expose Instron to excessive
financial and operating risks associated with the execution of such a
transaction, particularly in view of the substantial management resources that
would be required to be devoted to such an acquisition. The Instron Board
concluded that a potential sale of Instron was the alternative that would most
likely allow Instron to satisfy the objectives of increasing shareholder value
and providing liquidity to the Instron stockholders.


     Following the Instron Board's decision to explore a potential sale of the
Company, The Beacon Group recommended at the August 11, 1998 Instron Board
meeting that Instron implement a multi-step process in order to solicit
potential bids. The first step would be a broad marketing effort designed to
attract as wide and competitive a field of interested parties as possible. The
second step would be to seek more specific proposals from a smaller group of
interested parties, whose offers would be evaluated based upon such criteria as
price, form of consideration and certainty of consummation of a transaction.
Pursuant to this bidding process, the smaller group of interested parties would
submit competing proposals to acquire Instron or its assets. As the third step,
Instron would enter into exclusive negotiations concerning a definitive
agreement with the party whose bid would be most likely to provide the best
value for the Instron stockholders. According to The Beacon Group, this process
was preferable to other alternatives, such as negotiating only with one party
throughout the process, because in a competitive bidding process parties were
more likely to submit their highest bid to avoid being outbid by a competing
party. Thus, in the opinion of The Beacon Group, this multi-step process was
most likely to increase the amount of consideration to be received by the
Instron stockholders.



     Following this discussion, the Instron Board decided to adopt The Beacon
Group's recommendation to solicit interest from potential acquirors using a
multi-step process designed to result in competitive bidding for the Company.
The Instron Board also authorized management, with the assistance of Instron's
financial and legal advisors, to prepare a confidential information package for
distribution to potential buyers and to enter into confidentiality agreements
with potential buyers. In connection with authorizing the solicitation of


                                       13
<PAGE>   24


bids, the Instron Board did not make it a condition to any potential transaction
that current management maintain an equity interest in Instron following such
transaction.


     Following the August 11, 1998 Instron Board meeting, The Beacon Group began
the process of soliciting the interest of 49 parties in merging with or
acquiring Instron ("Phase I"). These potential buyers were comprised of certain
private companies, certain publicly traded companies engaged in businesses
related to one or more of Instron's businesses ("strategic buyers"), and
financial buyers engaged in the business of pursuing investment opportunities.
As part of such solicitation, The Beacon Group contacted senior executives or
directors of such potential buyers to inquire as to their interest in exploring
a possible business combination transaction with Instron. These potential buyers
were asked to execute a confidentiality agreement before The Beacon Group would
be permitted to distribute confidential information packages regarding Instron
to such potential buyers. A total of 23 potential buyers executed
confidentiality agreements and received confidential information packages. In
connection with the distribution of the confidential information packages, these
potential buyers were asked to submit indications of interest concerning a
possible business combination or acquisition transaction with Instron not later
than the end of the first week of January 1999. The other 26 potential buyers
who were contacted indicated to The Beacon Group that they did not have an
interest in exploring a transaction with Instron at that time.

     At a meeting of the Instron Board held on November 4, 1998, The Beacon
Group updated the Instron Board on The Beacon Group's progress in soliciting
indications of interest from potential buyers. The Beacon Group informed the
Instron Board that it had received a number of preliminary indications of
interest from certain potential buyers and that it was continuing its efforts to
contact other potential buyers. At the November 4 meeting, The Beacon Group also
advised the Instron Board with respect to recent adverse conditions in the
financing markets and the markets for mergers and acquisitions, recent declines
in the operating results and valuation of Instron's principal competitor, and
recent comparable mergers and acquisitions activity in the analytical instrument
industry. However, The Beacon Group also noted that the financing markets and
the mergers and acquisitions markets appeared to be stabilizing. The Instron
Board then authorized The Beacon Group to continue its marketing efforts.

     At a meeting of the Instron Board held on December 9, 1998, The Beacon
Group again updated the Instron Board on The Beacon Group's progress in
soliciting indications of interest from potential buyers. The Beacon Group also
noted that the mergers and acquisitions markets had continued to strengthen in
conjunction with the equity markets, but that the markets for acquisition
financing had not improved significantly making such financing more expensive
and difficult to obtain. At this meeting, The Beacon Group informed the Instron
Board that it was nearing the completion of its solicitation of preliminary
indications of interest and that it would at that time begin the second phase of
the process, after which The Beacon Group would make a formal presentation to
the Instron Board before beginning the final phase.


     At the end of Phase I, The Beacon Group received ten preliminary
indications of interest from potential buyers who had received confidential
information packages. Of these indications of interest, five involved a merger
with a strategic buyer and five involved a recapitalization merger pursuant to
which a financial buyer would make an investment in Instron that would result in
Instron becoming a private company. These indications of interest either (i)
specified a price or range of prices to be paid to the Instron stockholders from
$15.00 to $24.00 per share or (ii) indicated that the potential buyer would
consider paying a premium to the then current trading price of the Instron
Common Stock. In these latter bids, the amount of the potential premium was not
specified.



     After receiving these ten indications of interest, Instron directed The
Beacon Group to invite the five potential buyers which either in their bids or
in conversations with The Beacon Group, had indicated a willingness to pay a
significant premium to the then current trading price of the Instron Common
Stock, to participate in the next phase of the bidding process ("Phase II"). In
connection with Phase II of the bidding process, each of these five potential
buyers (the "Phase II Bidders") were permitted to conduct preliminary due
diligence on Instron and were given access to a data room in which Instron had
assembled various


                                       14
<PAGE>   25


materials and documentation concerning the Company's business and operations. In
addition, in January and February of 1999, four of the Phase II Bidders
(including Kirtland) attended presentations by Instron's management concerning
its business and operations. As part of the Phase II process, The Beacon Group
requested that each of the Phase II Bidders submit, on or about February 19,
1999, a formal proposal (a "Phase II Proposal") specifying an estimated price
that such bidder might be willing to pay to the Instron stockholders, an outline
of any significant comments or requested changes to a draft of a merger
agreement that was provided to such bidders, such bidder's intentions with
respect to Instron's current management, a description of any additional due
diligence items or activities that such bidder would expect to undertake, the
status of any proposed financing for the transaction, and any other significant
conditions relating to the transaction. The Beacon Group informed each of the
Phase II Bidders that following February 19, 1999, Instron would evaluate the
Phase II Proposals and select potential buyers with which to conduct a final
phase of negotiations with a view to receiving a final proposal from the Phase
II Bidders.


     At the end of the Phase II process, another party submitted a preliminary
indication of interest which was rejected because it was at a price
significantly below the other indications of interest and contained other terms
and conditions which made the bid unattractive.

     In connection with the Phase II process, only two of the five Phase II
Bidders submitted written proposals. Kirtland's Phase II Proposal expressed an
interest in pursuing a leveraged recapitalization merger with Instron pursuant
to which substantially all of the Instron stockholders would receive cash in the
merger at an estimated price per share of $22.00. Kirtland's proposal required
the continued participation and involvement of the existing senior management of
Instron and was conditioned upon, among other things, the execution of mutually
acceptable definitive documentation, the completion by Kirtland of further due
diligence satisfactory to Kirtland, the receipt by Kirtland of debt financing on
terms satisfactory to Kirtland and the negotiation of satisfactory arrangements
with the existing senior management of Instron concerning a continued ownership
interest in Instron following the transaction. Kirtland's proposal also included
initial comments from its legal counsel on the draft of the merger agreement.

     The other Phase II Proposal was submitted by a Phase II Bidder that, like
Kirtland, also was a financial buyer ("Bidder A"). Pursuant to its Phase II
Proposal, Bidder A expressed an interest in pursuing a leveraged
recapitalization merger with Instron at an estimated price per share of $22.50.
Bidder A's proposal also provided for the continued participation and
involvement of the existing senior management of Instron and was conditioned
upon, among other things, the completion by Bidder A of further due diligence
satisfactory to Bidder A and the receipt by Bidder A of debt financing on terms
satisfactory to Bidder A. Bidder A's proposal did not include any comments from
its legal counsel on the draft of the merger agreement. Bidder A also expressed
to The Beacon Group its desire to negotiate the terms of any proposed
transaction on an exclusive basis with Instron.


     At a meeting of the Instron Board held on March 10, 1999, the Instron Board
formed the Special Committee, consisting of Mr. Young, Dennis J. Moore and John
F. Smith, to consider and evaluate the two Phase II Proposals and any other
proposals that might be received by Instron. The Instron Board selected Messrs.
Young, Moore and Smith to serve as the members of the Special Committee because
they were not employed by Instron and would neither be employed by nor own an
equity interest in Instron following consummation of a transaction. In addition,
unlike the other two non-employee directors who also would not have a continuing
equity investment in Instron following a transaction, Messrs. Young, Moore and
Smith also indicated that their schedules would permit them to attend the
numerous Special Committee meetings which were likely to be held in the next
several months. The Instron Board also authorized the Special Committee to
participate in the negotiations of the material terms and conditions of the
proposed transactions under consideration and to recommend to the Instron Board
the advisability of entering into a definitive agreement with respect to any
such transaction. The Instron Board formed the Special Committee primarily
because it believed that a recapitalization transaction in the form proposed by
each of Kirtland and Bidder A might present potential conflicts of interest for
Instron's senior management and certain members of the Instron Board, who,
unlike the other Instron stockholders, would have a continuing equity interest
in Instron following consummation of such a transaction. The Instron Board also
considered the fact that, in view of the foregoing potential conflicts of
interest of Instron's senior management, it would be advisable for senior

                                       15
<PAGE>   26


management to retain separate legal counsel to advise it in connection with the
proposed transactions under consideration. For the same reason, the Instron
Board deemed it advisable that the Other Investors retain separate legal counsel
in connection with the proposed transactions under consideration. Subsequent to
the March 10, 1999 Instron Board meeting, the Management Investors and the Other
Investors each retained separate legal counsel. The Instron Board and the
Special Committee also considered the fact that two of the thirteen managing
directors of The Beacon Group were limited partner investors in Kirtland, one of
whom was actively involved in advising the Instron Board and the Special
Committee during the bidding process. However, the Instron Board and the Special
Committee noted that these individuals were passive investors in Kirtland who
together owned an approximately 0.12% limited partner interest in Kirtland and
did not control in any way the actions of Kirtland. Moreover, two other senior
professionals of The Beacon Group with no economic interest in Kirtland were
actively involved in advising the Instron Board and the Special Committee during
the bidding process. In addition, the Instron Board and the Special Committee
noted that under the terms of The Beacon Group's engagement with Instron, The
Beacon Group's fee percentage would increase as the price to be paid to the
Public Stockholders in any transaction increased. Accordingly, the Instron Board
and the Special Committee believed that despite the economic interest in
Kirtland held by the two managing directors of The Beacon Group, the terms of
The Beacon Group's engagement provided a substantially greater economic
incentive to assist Instron in obtaining the highest price for the stockholders
in any transaction. In view of the foregoing, the Instron Board and the Special
Committee concluded that the aforementioned relationship between the two
managing directors of The Beacon Group and Kirtland would not affect The Beacon
Group's ability to act independently and impartially as financial advisor to the
Instron Board and the Special Committee.


     At the March 10, 1999 Instron Board meeting, The Beacon Group advised the
Instron Board with respect to the status of the bidding process including its
analysis of the two Phase II Proposals that had been received and the additional
preliminary indication of interest. At this meeting, The Beacon Group provided
the Instron Board with a detailed analysis of the steps that The Beacon Group
had undertaken in the Phase I and Phase II bidding process. This analysis
included a description of the overall timetable for the Phase I and Phase II
bidding process, a summary of the efforts made by The Beacon Group to contact
potential interested parties, a summary of the preliminary indications of
interest received to date in the bidding process, a review of the management
presentations attended by certain Phase II Bidders, an overview of the contacts
made and discussions with Kirtland and Bidder A, a discussion of valuation
considerations that supported the range of the per share prices proposed by
Kirtland and Bidder A, and a detailed timetable for the final phase of the
process. The Beacon Group also reviewed with the Instron Board the additional
preliminary indication of interest that was received in the Phase II process.

     To facilitate the Instron Board's review of the two Phase II Proposals, The
Beacon Group also reviewed certain qualitative aspects of these proposals,
including the sources and availability of the debt financing required under the
proposals, the certainty of consummating a transaction, the approvals required
to consummate a transaction, the expected level of participation and involvement
in the company by senior management following consummation of a transaction and
the likelihood that a transaction would qualify for recapitalization accounting
treatment. The Beacon Group noted in particular that each of the proposals was
conditioned on further due diligence and the securing of debt financing. Both
The Beacon Group and Instron's legal counsel advised the Instron Board that
Instron should not grant exclusivity to either Kirtland or Bidder A but should
continue the bidding process with both of them and attempt to obtain, among
other things, (i) a higher price per share to be paid to the Instron
stockholders in a transaction, (ii) greater certainty with respect to any debt
financing required for a transaction and (iii) more specific terms of
management's continued involvement in the company following consummation of a
transaction.

     Immediately following the March 10, 1999 Instron Board meeting, the Special
Committee met to discuss the remainder of the bidding process and the timing of
such process. At this meeting, Instron's legal counsel advised the Special
Committee with respect to the Special Committee's legal responsibilities and the
legal principles applicable to, and the legal consequences of, actions taken by
the Special Committee with respect to the Phase II Proposals made by Kirtland
and Bidder A as well as any other proposals that may be made in the future
concerning a potential transaction involving the company. In particular,
Instron's legal counsel

                                       16
<PAGE>   27

advised the Special Committee with respect to the Special Committee's fiduciary
duties generally, the ability of the Special Committee to withdraw or modify its
recommendation of any transaction and the provisions of the merger agreement
relating thereto, and the necessity for obtaining shareholder approval of any
proposed transaction. The Special Committee then considered the recommendations
made by Instron's financial and legal advisors at the March 10, 1999 Instron
Board meeting and concluded that Instron should adopt such recommendations and
proceed to the final phase of the bidding process.

     Promptly following the meetings of the Instron Board and the Special
Committee on March 10, 1999, The Beacon Group contacted Kirtland and Bidder A
(the "Phase III Bidders"), each of whom continued to express an interest in
pursuing a recapitalization transaction with Instron. The Beacon Group informed
the Phase III Bidders that the Instron Board had formed the Special Committee
and had authorized the Special Committee to participate in the negotiations of
the material terms and conditions of any proposed transaction and to recommend
to the Instron Board the advisability of entering into a definitive agreement
with respect thereto. The Beacon Group also advised Kirtland and Bidder A that
Instron was not prepared to negotiate the terms of a proposed transaction
exclusively with either of them. The Beacon Group then invited the Phase III
Bidders to participate in the third and final phase of the bidding process
("Phase III"). In this regard, the Phase III Bidders were given the opportunity
to perform extensive due diligence on Instron, including the examination of
additional documentation requested by them or their financing sources, touring
Instron's United States and European facilities and interviewing Instron's
senior management. The Phase III Bidders were also given the opportunity to
comment further on a form of merger agreement that had been revised to reflect a
recapitalization transaction. As part of the Phase III process, each of the
Phase III Bidders were asked to complete their due diligence and submit a final
proposal to The Beacon Group by April 5, 1999.

     During the period of March 21 through March 24, 1999, representatives of
Kirtland met with members of Instron's senior management, including Mr.
McConnell, and representatives of The Beacon Group in Germany and the United
Kingdom to tour Instron's research and development and manufacturing operations
in Darmstadt, Germany and High Wycombe, U.K., to meet members of Instron's
management teams at these facilities and to visit certain of Instron's
customers. During the period of March 24 through March 27, 1999, representatives
of Bidder A participated in a substantially similar tour of Instron's operations
in Darmstadt and High Wycombe. During this period, each of Kirtland's and Bidder
A's legal counsel performed extensive due diligence on Instron, requesting
various documentation from Instron and visiting Instron's Canton, Massachusetts
headquarters. Representatives of Kirtland and Bidder A also visited Instron's
headquarters to perform additional financial due diligence.

     During the last two weeks of March 1999, legal counsel for the Phase III
Bidders reviewed the draft of the recapitalization merger agreement that had
been distributed to the Phase III Bidders. On March 18, 1999, Bidder A's legal
counsel provided Instron with a memorandum summarizing Bidder A's preliminary
comments on the draft of the recapitalization merger agreement that had been
distributed to the Phase III Bidders. On March 25, 1999, Kirtland's legal
counsel provided Instron with detailed comments on the draft of the
recapitalization merger agreement that had been distributed to the Phase III
Bidders.

     On March 30, 1999, the Special Committee held a meeting to discuss the
status of the Phase III bidding process. Prior to this meeting, the Special
Committee received materials from Instron's legal and financial advisors
summarizing the status of each of the Phase III Bidders' legal and financial due
diligence and the negotiations with their legal counsel concerning the proposed
terms of the recapitalization merger agreement. The Special Committee also
received copies of Kirtland's detailed comments on the draft of the
recapitalization agreement, a proposed revised draft of the recapitalization
merger agreement responding to Kirtland's comments, the memorandum prepared by
Bidder A's legal counsel concerning its preliminary comments on the draft of the
recapitalization merger agreement, and a proposed revised draft of the
recapitalization agreement responding to such comments. At the March 30, 1999
meeting, the Special Committee discussed the fact that Kirtland had
substantially completed its legal and financial due diligence and had engaged in
extensive negotiations with Instron's legal counsel concerning the terms of the
recapitalization merger agreement. The Special Committee also discussed its
concern that, in contrast to Kirtland's progress, Bidder A was still in the
process of conducting its legal and financial due diligence and had not yet
provided Instron with a detailed markup of the recapitalization merger
agreement.
                                       17

     On April 5, 1999, The Beacon Group received final proposals (the "Phase III
Proposals") from each of the Phase III Bidders, accompanied by drafts of debt
financing commitment letters from such bidders' proposed lenders. Kirtland's
Phase III Proposal contemplated a recapitalization merger pursuant to which the
Instron stockholders (other than certain management and non-management
stockholders of Instron who Kirtland would require to have a continuing equity
interest in the Company following consummation of the transaction) would receive
$20.50 per share in cash. Kirtland's proposal stated that, based upon
conversations between Kirtland and members of Instron's senior management,
Kirtland believed that it would be able to quickly agree on the arrangements for
management's ongoing ownership interest in the company. Kirtland's Phase III
Proposal also provided that the financing required to complete the transaction
would come from equity investments by Kirtland, members of Instron's management
and certain other non-management stockholders of Instron, and a combination of a
revolving credit facility and high yield debt. Kirtland's Phase III Proposal
also provided for a number of conditions to Kirtland's obligation to consummate
a transaction with Instron. These conditions consisted, among other things, of:
(i) the negotiation of arrangements with Instron's management concerning its
continued equity investment in Instron; (ii) revenues and earnings for Instron's
fiscal quarter ended April 3, 1999 being consistent with projections previously
provided to Kirtland in connection with its financial due diligence review of
Instron; (iii) Kirtland's lenders being reasonably satisfied with the results of
their due diligence review of Instron, which was expected to be completed within
two weeks; and (iv) Instron having debt (net of cash) at the closing of the
transaction not in excess of $11.5 million (the "Net Debt Closing Condition").



     Bidder A's Phase III Proposal also contemplated a recapitalization merger
pursuant to which the Instron stockholders (other than certain management
stockholders and potentially non-management stockholders of Instron who would
have a continuing equity interest in the Company following consummation of the
transaction) would receive $20.00 per share in cash. Bidder A's proposal stated
that prior to executing a definitive merger agreement, Bidder A anticipated
finalizing arrangements with Instron's management and other non-management
stockholders concerning their ongoing ownership interest in the Company. Bidder
A's Phase III Proposal also provided that the financing required to complete the
transaction would come from equity investments by Bidder A, members of Instron's
management and certain other non-management stockholders of Instron, and a
combination of a revolving credit facility, high yield debt and mezzanine
financing in the form of senior preferred equity. Bidder A's Phase III Proposal
was accompanied by commitment letters from its lender that set forth the terms
of the revolving credit, high yield debt and mezzanine financing to be provided
by such lender. Bidder A indicated in its Phase III Proposal that it had
conducted significant due diligence and to date it had not identified any
material issues. Bidder A stated that it expected to complete its legal and
financial due diligence by April 14, 1999. In addition, Bidder A indicated in
its Phase III Proposal that it had provided summary terms of the arrangements
with Instron's management concerning their ongoing ownership interest in the
company to management and management's legal counsel. Bidder A's Phase III
Proposal also indicated that it would need to review the results of Instron's
fiscal quarter ended April 3, 1999 prior to entering into a definitive agreement
with Instron with respect to a transaction. Finally, Bidder A stated in its
Phase III Proposal that the $20.00 per share price was below the $22.50 per
share price referred to in its Phase II Proposal as a result of several factors,
including, without limitation, the results of obtaining definitive terms of
available bank financing and the amount of expenses to be incurred by Instron in
connection with the transaction.


     On April 7, 1999, the Special Committee met to discuss the Phase III
Proposals submitted by Kirtland and Bidder A. In order to facilitate the Special
Committee's review of the two Phase III Proposals, The Beacon Group reviewed
certain quantitative aspects of these proposals, including the proposed cash
purchase price, the financing and capital structure contemplated by the
proposals and the material terms and conditions of the financing commitments
that had accompanied each of the proposals. The Beacon Group also reviewed for
the benefit of the Special Committee certain qualitative aspects of each of the
Phase III Proposals, including the sources and availability of the debt
financing required under the proposals, the certainty of consummating a
transaction with each of the Phase III Bidders in view of the conditions set
forth in their respective Phase III Proposals, and the expected level of
participation and involvement in the company by management and certain
non-management stockholders following consummation of the proposed transaction.

                                       18
<PAGE>   29

In addition, Instron's legal counsel updated the Special Committee on the status
of negotiations of the proposed merger agreements with each of Kirtland and
Bidder A.

     Following The Beacon Group's review of the Phase III Proposals at the April
7, 1999 Special Committee meeting, certain members of the Special Committee
expressed some disappointment at the pricing of the two proposals, particularly
in view of the fact that the two Phase III Bidders had reduced their proposed
cash purchase price significantly from their previous proposals. At the meeting,
the Special Committee also discussed, with advice from The Beacon Group and
Instron's legal counsel, the implications of rejecting both Phase III Proposals.
Following a discussion by the Special Committee, the Special Committee concluded
that neither of the Phase III proposals should be accepted at the current time
and that The Beacon Group should extend the bidding process over the next
several weeks. The Special Committee decided that, during this time, the two
Phase III Bidders would be asked to reconsider their proposed pricing and that
The Beacon Group would contact certain potential strategic buyers who had been
contacted earlier in the process, but who had not been interested at that time
in exploring a possible transaction with Instron. The Special Committee
concluded that if either of the two Phase III Bidders indicated a willingness to
increase their proposed cash purchase price or amended its proposal to increase
its proposed cash purchase price to at least the range of the Phase II
Proposals, then at such time the Special Committee would consider whether to
proceed to exclusive negotiations with such bidder.

     Following the April 7, 1999 meeting of the Special Committee, The Beacon
Group contacted Kirtland and Bidder A to report the results of the Special
Committee's meeting and, in particular, to express the Special Committee's
disappointment with the reduction of the bidders' proposed cash purchase price
from the pricing set forth in their Phase II Proposals. The Beacon Group also
informed the two bidders that the Special Committee would likely look favorably
on a significant increase in their pricing for a transaction to at least the
range of the Phase II Proposals, but that the Special Committee was not prepared
to continue negotiations at the present pricing. The Beacon Group also informed
the two Phase III Bidders that the Special Committee had authorized The Beacon
Group to contact certain potential strategic buyers who earlier in the process
had not been interested in exploring a possible transaction with Instron.


     On April 13, 1999, representatives of Kirtland met with Messrs. McConnell
and Moulding and representatives of The Beacon Group. At this meeting, Kirtland
expressed its continued strong interest in pursuing a transaction with Instron
and indicated a willingness to increase its proposed cash purchase price. After
significant discussions and negotiation, Kirtland increased its proposed cash
purchase price to $22.00 per share, provided that Instron agree that following
execution of a merger agreement and prior to consummation of a transaction
Instron would not pay any dividends to holders of Instron Common Stock,
including Instron's regular quarterly dividend. Kirtland also conditioned its
revised bid (the "Revised Kirtland Phase III Proposal") on certain
non-management stockholders of Instron (the Other Investors) participating in
the equity ownership of Instron following the transaction through the ownership
of preferred stock. Following this meeting, The Beacon Group informed Bidder A
that its proposed bid of $20.00 was no longer competitive and that to remain
competitive in the bidding process it would have to increase the price of its
bid significantly. On the same date, a representative of Kirtland met with
Messrs. Hindman and Burr to discuss Kirtland's interest in pursuing a
transaction with Instron.


     On April 14, 1999, Bidder A informed The Beacon Group that it continued to
have an interest in pursuing a transaction with Instron, but that it would not
increase its price beyond $20.50 per share. Bidder A also emphasized its
experience in taking public companies private and its belief that its proposal
would provide greater certainty of consummating a transaction.

     On April 15, 1999, the Special Committee held a meeting to discuss the
status of the Phase III Proposals, including The Beacon Group's conversations
with Kirtland and Bidder A, the results of The Beacon Group's efforts to contact
other strategic buyers and the status of negotiations of the merger agreements.
The Beacon Group informed the Special Committee that none of the potential
strategic buyers that were contacted expressed an interest in exploring a
possible transaction with Instron. The Beacon Group reported that these
potential buyers either lacked the management resources at that time to explore
a strategic

                                       19
<PAGE>   30

transaction with Instron or were at that time pursuing a strategic transaction
with another party that precluded them from participating in discussions with
Instron. Following The Beacon Group's report to the Special Committee, Instron's
legal counsel updated the Special Committee on the status of negotiations with
Kirtland and Bidder A concerning the terms of the proposed merger agreements.


     Following the updates provided by The Beacon Group and Instron's legal
counsel, the Special Committee discussed at the April 15 meeting the likelihood
that a strategic buyer would express an interest in exploring a potential
transaction with Instron at some later time, concluding that in view of the
length of the process undertaken by Instron to date (eight months) pursuant to
which 49 potential buyers were solicited and The Beacon Group's latest attempts
to resolicit the interest of certain of these potential buyers, it was not
likely that a strategic or other buyer would express an interest in exploring a
transaction with Instron in the foreseeable future. During this discussion, the
Special Committee also considered Instron's then current and projected financial
performance, Instron's business strategy and the uncertainties associated with
the successful implementation of that strategy. In addition, the Special
Committee considered the uncertainties associated with terminating the sale
process at that time and soliciting potential buyers at some time in the future
in view of the fact that Instron had received the bids from Kirtland and Bidder
A. Following this discussion and a review of the terms and conditions of the
Revised Kirtland Phase III Proposal and Bidder A's Phase III Proposal, the
Special Committee concluded that it was desirable to proceed with Kirtland
rather than Bidder A because Bidder A was not willing to increase its price
beyond $20.50 per share while Kirtland was willing to proceed with a transaction
at $22.00 per share. The Special Committee then authorized Mr. Young to
participate in exclusive negotiations with Kirtland concerning a
recapitalization transaction on the terms set forth in the Revised Kirtland
Phase III Proposal upon the satisfaction of the following conditions: (i)
receipt by Kirtland of an executed commitment letter relating to its procurement
of high yield debt financing; (ii) agreement and understanding by management of
Instron concerning the scope of the Net Debt Closing Condition; (iii) the Other
Investors indicating that they were in agreement with the general terms
concerning their equity ownership in Instron following completion of the
transaction; and (iv) Instron's independent public accountants concluding as a
preliminary matter that the transaction as proposed by Kirtland would qualify
for recapitalization accounting treatment.


     On April 20, 1999, Mr. Young reported to the other members of the Special
Committee that Kirtland had satisfied the four conditions discussed at the April
15, 1999 Special Committee meeting and that Instron should therefore proceed
with exclusive negotiations with Kirtland, which the members of the Special
Committee agreed was appropriate. On April 20, 1999, Instron and Kirtland
entered into an exclusivity agreement (the "Exclusivity Agreement") pursuant to
which the parties agreed to negotiate exclusively with each other until April
30, 1999.


     Following the execution of the Exclusivity Agreement, the parties,
primarily through their legal counsel and, in the case of Instron, with the
assistance of The Beacon Group, focused on negotiating the final terms of the
Merger Agreement and the related documentation. In addition, the Other Investors
and the Management Investors, through their respective legal counsel, began
negotiations with Kirtland's legal counsel. These negotiations continued for a
period of approximately three weeks, and centered primarily upon: (i) the amount
of equity participation by the Management Investors and the Other Investors in
Instron following completion of the transaction, and (ii) certain modifications
to the Management Investors' existing employment arrangements that Kirtland was
seeking. In this regard, Kirtland, as is its normal practice, was motivated by a
desire to (i) achieve recapitalization accounting treatment, and (ii) maximize
the level of participation by the Management Investors. These negotiations did
not involve valuation issues as Kirtland had agreed that any investment by the
Management Investors and the Other Investors in Instron following completion of
the transaction would be on a basis equivalent to Kirtland's investment.


     On May 4, 1999, the Special Committee and the Instron Board held meetings
to consider the Merger Agreement and the Transactions. At the Special Committee
meeting, The Beacon Group and Instron's legal counsel updated the Special
Committee on the events since the April 15, 1999 meeting, including the
negotiations of the Merger Agreement and the arrangements with the Other
Investors and the Management Investors. The Beacon Group then summarized for the
Special Committee its financial analysis of the Transactions that it had
prepared for the Instron Board meeting that was to follow the Special Committee
                                       20
<PAGE>   31

meeting. The Beacon Group also informed the Special Committee that it was
prepared to render its oral opinion to the Instron Board to the effect that as
of the date thereof, and based on the assumptions and subject to the limitations
and qualifications set forth therein, the Cash Merger Consideration was fair
from a financial point of view to the Public Stockholders. Following a
discussion by the Special Committee, the Special Committee unanimously
recommended that the Instron Board approve the Merger Agreement and the
Transactions and that the Instron Board recommend that the Instron stockholders
approve the Merger Agreement and the Transactions.

     Immediately following the May 4, 1999 meeting of the Special Committee, the
Instron Board met to discuss the approval of the Merger Agreement and the
Transactions. At the Instron Board meeting, the Special Committee, certain
members of senior management of Instron, The Beacon Group and Instron's legal
counsel updated the Instron Board on the events since the March 10, 1999 meeting
of the Instron Board. Instron's legal counsel also gave a presentation to the
Special Committee on the timetable for the execution of definitive documentation
relating to the Transactions and certain disclosure issues relating thereto. The
Beacon Group then provided the Instron Board with a detailed and lengthy
presentation of its financial analysis of the Transactions. Following this
presentation, The Beacon Group rendered its oral opinion to the Instron Board to
the effect that as of the date thereof, and based on the assumptions and subject
to the limitations and qualifications set forth therein, the Cash Merger
Consideration was fair from a financial point of view to the Public
Stockholders. Following a discussion by the Instron Board, the Instron Board
approved the Merger Agreement and the Transactions, with Messrs. Hindman, Burr
and McConnell abstaining from the vote in view of their participation in the
Transactions.

     The parties finalized negotiations of the terms of the Merger Agreement and
the related agreements during the period of May 4 to May 6, 1999. On the evening
of May 6, 1999, the Merger Agreement and the related agreements were executed.
On May 7, 1999, Instron and Kirtland jointly issued a press release announcing
the proposed transaction.

THE SPECIAL COMMITTEE'S AND THE INSTRON BOARD'S RECOMMENDATION

     As discussed above under "-- Background of the Merger," the Special
Committee unanimously recommended that the Instron Board approve the Merger
Agreement and the Transactions and that the Instron Board recommend that the
Instron stockholders approve the Merger Agreement and the Transactions.
Following the unanimous recommendation of the Special Committee, the Instron
Board, other than Harold Hindman, George S. Burr and Mr. McConnell, unanimously
determined that the Merger Agreement and the Transactions, including the Merger,
were fair to and in the best interests of the Instron stockholders and
recommended that the stockholders approve the Merger Agreement and the
Transactions. Messrs. Hindman, Burr and McConnell abstained from voting on the
Merger Agreement and the Transactions because each of them has an interest in
the Merger as a member of the Investor Group. The Special Committee and the
Instron Board recommend that the stockholders vote "For" the approval of the
Merger Agreement and the Transactions.

     In reaching its determination that the Merger Agreement and the
Transactions, including the Merger, are fair to and in the best interests of the
Instron stockholders, each of the Instron Board and the Special Committee
consulted with Instron's financial and legal advisors, drew on its knowledge of
the business, operations, properties, assets, financial condition, operating
results, historical market prices and prospects of Instron and considered the
following factors, each of which the Instron Board and the Special Committee
deemed favorable:


          (1) the belief of the Instron Board and the Special Committee that the
              Merger represents a more desirable alternative than continuing to
              operate Instron as a public company. In particular, the Instron
              Board and the Special Committee believe that the Instron Common
              Stock was an illiquid security and this illiquidity had an adverse
              effect on the trading price of the Instron Common Stock. In this
              regard, the Instron Board and the Special Committee noted the
              limited trading volume of the Instron Common Stock on AMEX, as
              evidenced by its average monthly trading volume and the limited
              public float of such stock resulting in part from the significant


                                       21
<PAGE>   32


          holdings of the executive officers and directors of Instron. In
          addition, the Instron Board and the Special Committee believe that
          continuing to operate Instron as a public company entails meaningful
          risks in the execution of Instron's business strategy. In particular,
          the Instron Board and the Special Committee believe that executing
          this strategy would include making large acquisitions that would
          result in a substantial increase in the debt to equity ratio of
          Instron. The Instron Board and the Special Committee believe that such
          action involves substantial investment risks to the stockholders of
          Instron. After considering the foregoing, the Instron Board and the
          Special Committee concluded that, while Instron's business strategy
          could ultimately prove successful, the recapitalization of Instron
          would provide all stockholders with liquidity for their investment at
          a price that exceeds the all time highest market price of the Instron
          Common Stock. See "-- Background of the Merger" and "-- Instron
          Projections."


          (2) the Instron Board and the Special Committee believed that the
              Merger was the best offer reasonably available for the Instron
              stockholders. The Instron Board and the Special Committee believed
              that there were no other prospective buyers that both had the
              financial ability to complete a strategic transaction and would be
              willing to pay an aggregate consideration greater than that to be
              paid by the Investor Group in the Merger. In seeking to maximize
              value to the Public Stockholders, Instron and its financial
              advisors instituted a multi-step process pursuant to which they
              solicited the interest of 49 prospective buyers, executed 23
              confidentiality agreements with prospective buyers and thereafter
              received 11 indications of interest at various times and, after
              conducting a formal bidding process, received two definitive
              proposals offering to acquire Instron. Of the two definitive
              proposals, Kirtland's proposal offered the highest price on a per
              share basis and contained fewer conditions than the other
              proposal. In addition, following receipt of the two definitive
              proposals, Instron and its financial advisors resolicited the
              interest of certain prospective buyers who earlier in the process
              had declined to make a definitive proposal for reasons unrelated
              to Instron and those prospective buyers who were contacted again
              declined to make a proposal. For these reasons and the other
              reasons described herein, the Instron Board and the Special
              Committee concluded that the Merger and the Transactions were fair
              to and in the best interests of Instron and the Public
              Stockholders. See "-- Background of the Merger" and " -- Opinion
              of Financial Advisors."


          (3) the relationship of the Cash Merger Consideration to the
              historical market prices for the Instron Common Stock and the fact
              that the Cash Merger Consideration represents a significant
              premium to recent historical trading prices of the Instron Common
              Stock and exceeds the all time highest market price of the Instron
              Common Stock. In addition, the Instron Board and the Special
              Committee considered the relationship of the Cash Merger
              Consideration to the current trading price of the Instron Common
              Stock and the fact that the Cash Merger Consideration represents a
              premium of $5.00 or 29.4% to the closing sale price of $17.00 for
              a share of Instron Common Stock as reported by AMEX on May 3,
              1999, the trading day immediately preceding the date on which the
              Special Committee and the Instron Board approved the Merger
              Agreement and the Transactions. See "Historical Market
              Information."


          (4) the oral opinion of The Beacon Group delivered to the Instron
              Board, which was confirmed by its written opinion to the Instron
              Board, dated as of May 6, 1999, to the effect that, based upon and
              subject to certain factors and assumptions stated therein, as of
              such date, the Cash Merger Consideration to be received in the
              Merger by the Public Stockholders was fair from a financial point
              of view to the Public Stockholders (a copy of which is attached to
              this Proxy Statement as Appendix B). See "-- Opinion of Financial
              Advisor."


          (5) the analyses performed by The Beacon Group in connection with
              rendering its fairness opinion, including The Beacon Group's
              comparable public company, comparable merger and acquisition
              transaction, discounted cash flow, leveraged recapitalization and
              implied premium analyses, as well as the relationship between the
              Cash Merger Consideration and Instron's book value, which as of
              March 31, 1999 was $11.18 per share, on a fully diluted basis,
              substantially below the Cash Merger Consideration. See "--Opinion
              of Financial Advisor."

                                       22
<PAGE>   33


          (6) the financial ability and willingness of the Investor Group to
              consummate the Merger. The Instron Board and the Special Committee
              considered the fact that the Equity Investor had obtained certain
              equity and debt commitments sufficient to provide the necessary
              financing with which to consummate the Transactions, including the
              Merger, and had delivered to the Instron Board and the Special
              Committee binding financing commitment letters provided by the
              Equity Investor's lenders. In this regard, the Instron Board and
              the Special Committee considered the fact that unlike many other
              recapitalization transactions similar in structure to the Merger,
              the Merger Agreement did not provide for an unlimited right by the
              Equity Investor to abandon the Merger and the other Transactions
              in the event that any of the conditions to the Equity Investor's
              debt financing were unable to be satisfied. Alternatively, the
              Merger Agreement provides that the Equity Investor will not be
              required to consummate the Transactions, including the Merger, if
              there shall have occurred any material disruption or material
              adverse change in the banking, financial or capital markets
              generally or in the market for senior credit facilities or for new
              issuances of high yield securities which has caused either of the
              Equity Investor's lenders to withdraw its commitment to provide
              financing. Based on the foregoing, the Instron Board viewed as
              reasonable the risk that the financing condition contained in the
              Merger Agreement would not be satisfied. See "-- Financing of the
              Merger" and "The Merger -- Terms of the Merger Agreement."



          (7) the terms and conditions of the Merger Agreement. In particular,
              the Instron Board and the Special Committee considered the fact
              that the Merger Agreement provided that, subject to the
              satisfaction of certain conditions, the Instron Board would be
              able to withdraw or modify its recommendation to the Instron
              stockholders regarding the Merger and enter into an agreement with
              respect to a more favorable transaction with a third party, if
              such a transaction becomes available prior to the consummation of
              the Merger. The Instron Board and the Special Committee also
              considered the fact that the Merger Agreement provided for the
              payment of liquidated damages equal to approximately 3% of the
              aggregate transaction value, as well as expense reimbursement
              obligations, which the Instron Board and the Special Committee
              believed would not have the effect of unreasonably discouraging
              competing bids. See "The Merger -- Terms of the Merger
              Agreement -- Solicitation of Acquisition Proposals,"
              "-- Termination" and "-- Fees and Expenses."



          (8) the fact that the Merger Agreement requires the Merger to be
              submitted to the Instron stockholders for approval, which allows
              for an informed vote of the Public Stockholders on the merits of
              the transaction without requiring a tender of shares or other
              potentially coercive transaction structure, and the fact that the
              Merger Agreement provides that it may be terminated by Instron if
              approval of the holders of two-thirds of the outstanding Instron
              Common Stock is not received. See "The Merger -- Terms of the
              Merger Agreement."


     The Instron Board and the Special Committee also considered the following
factors, all of which the Instron Board and the Special Committee considered as
negative factors, in its deliberations concerning the approval of the Merger
Agreement and the Transactions:

          (1) The Instron Board and the Special Committee considered the fact
              that consummation of the Merger would preclude the Public
              Stockholders from having the opportunity to participate in the
              future growth prospects of Instron. In addition, the Instron Board
              and the Special Committee recognized that the Other Investors and
              the Management Investors will have the opportunity to benefit from
              any increases in the value of Instron following the Merger by
              reason of their continuing equity interest in the Surviving
              Corporation and therefore may realize a substantial economic
              benefit from the transaction. In particular, the Instron Board and
              the Special Committee considered that the Other Investors and the
              Management Investors will own approximately 6.2% and 6.4%,
              respectively, of outstanding shares of Surviving Corporation
              Common Stock. The Instron Board and the Special Committee also
              considered that the Surviving Corporation will reserve
              approximately 10.0% of the Surviving Corporation Common Stock on a
              fully diluted basis (assuming the exercise of all options,
              including the Rollover
                                       23
<PAGE>   34

          Options) for the grant of options to management employees, of which
          4.0% will be granted to those Management Investors who are members of
          Instron's management upon consummation of the Merger. The Instron
          Board and the Special Committee further considered that certain
          Management Investors will amend their existing severance agreements or
          will enter into new agreements relating to deferred compensation with
          the Surviving Corporation, and that such amended or new agreements
          will provide for the payment to them of potential severance benefits
          and other compensation or benefits. See "-- Share Ownership of Instron
          Following the Merger" and "-- Conflicts of Interest."

          (2) The Instron Board and the Special Committee considered the fact
              that the options to purchase shares of Instron Common Stock
              previously granted to the Management Investors pursuant to
              Instron's stock option plans would become immediately exercisable
              as a result of the Merger. In addition, the Instron Board and the
              Special Committee considered the fact that the restrictions on the
              shares of Instron Common Stock previously issued to the Management
              Investors pursuant to Instron's stock option plans would lapse as
              a result of the Merger. The Instron Board and the Special
              Committee also considered that the Merger would result in a
              "change of control" under the terms of the severance agreements
              between Instron and certain of the Management Investors, which
              could result in such Management Investors receiving certain
              payments under such agreements in the event of the termination of
              their employment following the Merger. See "-- Conflicts of
              Interest."


          (3) The Instron Board and the Special Committee considered the
              potential conflicts of interest of the Management Investors and
              the Other Investors resulting from the foregoing economic and
              other benefits that might be realized by them. However, for the
              reasons discussed below, the Instron Board and the Special
              Committee believe that the procedures that were followed in the
              bidding process and in the negotiation of the Merger Agreement and
              the terms of the Transactions properly addressed these conflicts
              of interest and were fair to the Public Stockholders.



     The Special Committee noted that approximately 22.4% of the outstanding
shares of Instron Common Stock are held by persons who have committed to vote
their shares of Instron Common Stock in favor of the Merger Agreement and the
Transactions, including all of the Other Investors and the Management Investors.
The Special Committee also considered that the obligation of Instron to
consummate the Merger is not conditioned upon the favorable vote of a majority
of the Public Stockholders. Notwithstanding the absence of such a voting
requirement, the Special Committee believes that the procedure that was followed
in determining the purchase price to be paid to the stockholders of Instron was
fair to the Public Stockholders. As described above, the eight-person Instron
Board (three of whom (Messrs. McConnell, Hindman and Burr) are members of the
Investor Group) appointed as the only members of the Special Committee three
non-employee directors who were independent of the Investor Group and who would
not have a continuing equity interest in Instron following the Merger. The
Instron Board granted the Special Committee exclusive authority on behalf of the
Instron Board to review, evaluate, and negotiate the transaction proposed by
Kirtland. The Merger Agreement negotiated by the Special Committee contains
provisions that would enable the Instron Board to withdraw or modify its
recommendation to the stockholders regarding the Merger and to enter into an
agreement with respect to a more favorable transaction with a third party and
contains provisions (without which the Special Committee believes Kirtland would
not have entered into the Merger Agreement) imposing upon Instron a liquidated
damages fee and expense reimbursement obligations that, in the view of the
Special Committee, are reasonable and would not have the effect of unreasonably
discouraging competing bids. Further, the stockholders of Instron may dissent
from the Merger and be paid cash for the "fair value" of their shares as
determined in accordance with Massachusetts law. Thus, although the Merger is
not structured to require approval of a majority of the unaffiliated
stockholders, the Special Committee nevertheless believes, as of the date of
this Proxy Statement and for the reasons set forth above, the Merger is
procedurally fair to the Public Stockholders.



     In considering the fairness of the Merger, the Special Committee and the
Instron Board did not consider Instron's liquidation value because they did not
believe such value to be indicative of the value of Instron as

                                       24
<PAGE>   35


a going concern. However, the Special Committee believes Instron's liquidation
value, which takes into account the appreciated value of Instron's assets, would
be substantially below the Cash Merger Consideration.


     While the Instron Board and the Special Committee considered the foregoing
factors, they did not quantify or attach any particular weight to such factors,
and individual members of the Instron Board and the Special Committee may have
placed different emphasis on particular positive or negative factors in reaching
their determination that the Merger Agreement and the Transactions are fair to
and in the best interests of the Instron stockholders. However, in the opinion
of the Instron Board and the Special Committee, the positive factors set forth
above outweighed the negative factors set forth above and, accordingly, the
Instron Board and the Special Committee each approved the Merger Agreement and
the Transactions, including the Merger.

     If the Instron stockholders do not approve the Merger Agreement and the
Transactions, or if the Merger and the other Transactions are not consummated
for any other reason, the Instron Board expects that Instron will continue to
pursue its business objectives principally of (i) designing, developing,
manufacturing and servicing materials and structural testing systems, software
and accessories, and (ii) seeking opportunities to grow through acquisitions of
complementary or related businesses and technologies. In addition, Instron may
seek other business combination opportunities.

INSTRON PROJECTIONS

     In connection with Kirtland's review of Instron and in the course of the
negotiations between Instron and Kirtland described in "-- Background of the
Merger," Instron provided Kirtland and other interested parties with certain
non-public business and financial information. The non-public information
provided by Instron included certain projections of the future operating
performance of Instron (the "Instron Projections"). The Instron Projections
include management projections of, among other things, Instron's net sales, net
income and EBITDA. Instron provided certain projections as of February 1999
which covered the years 1999 through 2002. Subsequently, management reviewed
Instron's actual results in the first quarter of 1999 and in April 1999 revised
its projections for 1999 based on its review of the first quarter results and
other factors. The Special Committee and the Instron Board also reviewed the
Instron Projections in connection with approving the Merger Agreement and the
Transactions. The Instron Projections do not give effect to the Merger or the
financing thereof.

     Instron does not, as a matter of course, publicly disclose projections as
to future revenues or earnings. The Instron Projections were not prepared with a
view to public disclosure and are included in this Proxy Statement only because
such information was made available to Kirtland in connection with its due
diligence investigation of Instron and was considered by the Special Committee
and the Instron Board in connection with approving the Merger Agreement and the
Transactions. Accordingly, it is expected that there will be differences between
actual and projected results, and actual results may be materially different
than those set forth below. The Instron Projections were not prepared with a
view to compliance with the published guidelines of the Commission regarding
projections, nor were they prepared in accordance with the guidelines
established by the American Institute of Certified Public Accountants for
preparation and presentation of financial projections. Moreover,
PricewaterhouseCoopers LLP, Instron's independent auditors, has not examined,
compiled or applied any procedures to the Instron Projections in accordance with
standards established by the American Institute of Certified Public Accountants
and expresses no opinion or any assurance on their reasonableness, accuracy or
achievability. These forward-looking statements reflect numerous assumptions
made by Instron's management. In addition, factors such as industry performance,
general business, economic, regulatory, and market and financial conditions, all
of which are difficult to predict, may cause the Instron Projections or the
underlying assumptions to be inaccurate. Accordingly, there can be no assurance
that the Instron Projections will be realized, and actual results may be
materially more or less favorable than those contained in the Instron
Projections.

     The inclusion of the Instron Projections herein should not be regarded as
an indication that the Investor Group, the Special Committee, the Instron Board,
Instron or any of their respective financial advisors considered or consider the
Instron Projections to be a reliable prediction of future events, and the
Instron

                                       25
<PAGE>   36

Projections should not be relied upon as such. None of the Special Committee,
the Instron Board, Instron, the Investor Group, or any of their financial
advisors intends to update or otherwise revise the Instron Projections to
reflect circumstances existing after the date when made or to reflect the
occurrence of future events even in the event that any or all of the assumptions
underlying the Instron Projections are shown to be in error or to otherwise have
changed.

     The Instron Projections that Instron provided to Kirtland and that The
Beacon Group analyzed in giving its fairness opinion and the Special Committee
and the Instron Board reviewed in connection with approving the Merger Agreement
and the Transactions are set forth below:

OPINION OF FINANCIAL ADVISOR

     The Beacon Group acted as financial advisor to the Instron Board and the
Special Committee in connection with the Transactions, including the Merger. On
May 4, 1999, The Beacon Group rendered its oral opinion to the Instron Board to
the effect that, as of that date and based on and subject to the assumptions
made, matters considered and limits of the reviews undertaken by The Beacon
Group described in its opinion, the Cash Merger Consideration to be received by
the Public Stockholders pursuant to the Merger was fair from a financial point
of view to such stockholders. The Beacon Group subsequently confirmed this
opinion, as of May 6, 1999, in writing. This written opinion is referred to in
this Proxy Statement as the "Beacon Opinion."

     The full text of the Beacon Opinion is included in this Proxy Statement as
Appendix B. The Beacon Opinion is addressed to the Instron Board for its
information concerning the fairness from a financial point of view of the Cash
Merger Consideration and does not address the merits of the underlying decision
of Instron to engage in the Merger or the other Transactions and does not
constitute a recommendation to any holder of shares of Instron Common Stock as
to how such holder should vote with respect to the Merger Agreement or any other
matter relating to the Merger. The summary of the Beacon Opinion in this section
is qualified in its entirety by reference to the full text of the Beacon Opinion
included in this Proxy Statement as Appendix B.

                                       26

For specific information concerning the procedures followed, assumptions made,
matters considered and qualifications and limitations of the review undertaken
by The Beacon Group in connection with the Beacon Opinion, holders of shares of
Instron Common Stock should read the Beacon Opinion in its entirety.

     In connection with the Beacon Opinion, The Beacon Group reviewed, among
other things:

     - the Merger Agreement;

     - Annual Reports to stockholders and Annual Reports on Form 10-K of Instron
       for the five years ended December 31, 1998;

     - certain interim reports to stockholders of Instron and Quarterly Reports
       on Form 10-Q of Instron;

     - certain other communications from Instron to its stockholders;

     - internal financial analyses and forecasts of Instron prepared by
       Instron's management; and

     - the potential pro forma impact of the Merger on the Surviving
       Corporation.

     In addition, The Beacon Group held discussions with members of the senior
management of Instron regarding the past and current business, operations and
financial condition and future prospects of Instron, reviewed the reported price
and trading activity of the shares of Instron Common Stock, compared certain
financial and stock market information concerning Instron with similar
information for some other companies the securities of which are publicly
traded, reviewed the financial terms of some recent business combinations in
industries and markets The Beacon Group deemed relevant and performed other
studies and analyses that The Beacon Group considered appropriate, including an
analysis of the pro forma capitalization of Instron after giving effect to the
Merger and proposed financing arrangements related to the Merger.

     In preparing the Beacon Opinion, The Beacon Group assumed and relied
without independent verification on the accuracy and completeness of the
financial and other information reviewed by it for purposes of the Beacon
Opinion. With respect to the financial forecasts reviewed and discussed, The
Beacon Group assumed that they had been reasonably prepared on bases reflecting
the best currently available estimates and judgments of Instron's management as
to the future financial performance of Instron. We refer to these financial
forecasts in this Proxy Statement as the Instron Projections, and they are
included in this Proxy Statement on page 22. The Beacon Group did not make an
independent evaluation or appraisal of the assets and liabilities of Instron or
any of its subsidiaries, and The Beacon Group was not furnished with any such
evaluation or appraisal. The Beacon Opinion is necessarily based on economic,
market, financial and other conditions as they existed on, and could be
evaluated as of, the date of the Beacon Opinion.

     In evaluating the fairness of the Cash Merger Consideration from a
financial point of view, The Beacon Group also reviewed with the Instron Board
the breadth of the process undertaken by The Beacon Group to identify parties
potentially interested in effecting a transaction with Instron. In rendering the
Beacon Opinion, The Beacon Group considered the fact that, after contacting 49
potentially interested parties, no proposal was forthcoming that was more
attractive to the Instron stockholders than Kirtland's proposal.

     A summary of the material financial analyses used by The Beacon Group in
preparing the Beacon Opinion and presented by The Beacon Group to the Instron
Board on May 4, 1999 follows. This summary includes information presented in
tabular form. In order to understand fully the financial analyses performed by
The Beacon Group, the tables must be read together with the text of each
description. The tables alone do not constitute a complete description of the
financial analyses. Considering the data in the tables without considering the
full narrative description of the financial analyses, including the
methodologies and assumptions underlying the analyses, could create a misleading
or incomplete view of the financial analyses performed by The Beacon Group.


     Comparable Public Company Analysis. The Beacon Group reviewed and compared
financial information and public market multiples for Instron to corresponding
financial information and public market multiples for selected publicly traded
analytical instruments companies, which companies were considered by The Beacon
Group to be reasonably comparable to Instron for purposes of this analysis. The
Beacon Group selected


                                       27
<PAGE>   38


publicly traded companies with analytical instruments businesses focused on the
measurement of various properties across a range of end markets. The Beacon
Group included all of the selected companies in its analysis. The companies
listed in the following table, which are referred to in this Proxy Statement as
the "Comparable Companies," are the companies that The Beacon Group used for
this analysis:


COMPARABLE COMPANIES

<TABLE>
<S>                                           <C>
Beckman Coulter, Inc.                         MTS Systems Corporation
Bio-Rad Laboratories                          Thermoquest Corporation
Browne & Sharpe Manufacturing Company         Varian Associates
Mettler-Toledo International Inc.             Waters Corporation
Modern Controls, Inc.
</TABLE>

     Using publicly available information, The Beacon Group calculated and
analyzed, among other things:

     - the Equity Value (as defined below) of the Comparable Companies and
       Instron as a multiple of certain historical and projected financial
       criteria, including net income and tangible book value; and

     - the Aggregate Value (as defined below) of the Comparable Companies and
       Instron as a multiple of the latest 12 months', or "LTM," sales, earnings
       before interest, taxes, depreciation and amortization, or "EBITDA," and
       earnings before interest and taxes, or "EBIT."

     The "Equity Value" of each company was calculated by multiplying the number
of shares of common stock outstanding for each company by the closing market
price of the company's shares of stock on April 30, 1999, adjusted to include
the impact, if any, of outstanding options. The "Aggregate Value" of each
company was calculated by adding the Equity Value of the company to its Net Debt
(as defined below). The "Net Debt" of each company was calculated by adding the
book value of the company's debt, preferred stock and minority interest and
subtracting cash and cash equivalents. The estimated net income data for Instron
and for each Comparable Company was based on information obtained from
Institutional Brokers Estimate System.

     The following table sets forth information concerning the overall ranges of
Equity Value as a multiple of net income and tangible book value and the overall
ranges of Aggregate Value as a multiple of sales, EBITDA and EBIT for all of the
Comparable Companies, and separately for MTS Systems Corporation, which in The
Beacon Group's judgment is Instron's closest comparable publicly-traded company
in terms of certain markets served (the "MTS Trading Multiples"), and the
multiples of the same financial metrics for Instron based on (i) the $17.00 per
share closing price of the Instron Common Stock as of April 30, 1999 (the
"Instron Trading Multiples") and (ii) the $22.00 per share Cash Merger
Consideration (the "Cash Merger Consideration Multiples"):

</TABLE>

     The Beacon Group noted that, while in its judgment MTS Systems Corporation
was Instron's closest comparable company in terms of markets served, no publicly
traded company was directly comparable to Instron and that the Comparable
Companies included certain higher growth, higher technology companies

                                       28
<PAGE>   39

whose characteristics are materially different from Instron's. Therefore, The
Beacon Group deemed the mean and median multiples derived in the foregoing
analysis to be instructive.

     The Beacon Group calculated implied equity per share values for Instron
Common Stock by using Instron's balance sheet as of December 31, 1998, where
applicable, and by applying (1) Aggregate Value to LTM EBITDA multiples ranging
from 7.5x to 7.9x, (2) Aggregate Value to LTM EBIT multiples ranging from 11.1x
to 11.3x, (3) Equity Value to LTM net income multiples ranging from 14.8x to
16.8x and (4) Equity Value to 1999 estimated net income multiple of 13.1x, which
in each case were derived from the foregoing analysis, to Instron's LTM EBITDA,
LTM EBIT, LTM net income (in each case as of December 31, 1998) and estimated
1999 net income obtained from Institutional Brokers Estimate System,
respectively. Because MTS Systems Corporation is comparable to Instron in terms
of certain markets served, The Beacon Group also calculated an implied equity
value per share by applying MTS Systems Corporation's Aggregate Value to LTM
EBITDA multiple of 6.4x to Instron's LTM EBITDA as of December 31, 1998 and
using Instron's balance sheet as of December 31, 1998.

     The following table presents the ranges of implied equity per share values
for Instron Common Stock implied by these analyses compared with the $22.00 per
share Cash Merger Consideration:

     The Beacon Group noted that the Cash Merger Consideration exceeded the
range of implied equity per share values of Instron Common Stock produced by the
comparable public company analysis.



     Comparable Merger and Acquisition Transaction Analysis.  Using primarily
publicly available information, The Beacon Group reviewed and analyzed 16
selected merger and acquisition transactions involving other companies with a
focus on test and measurement in the analytical instruments industry and related
industries and derived certain financial ratios which it compared with the same
financial ratios for the Merger. While The Beacon Group noted that no merger and
acquisition transaction reviewed was directly comparable to the Merger, The
Beacon Group deemed three of the reviewed transactions most relevant in
evaluating the Cash Merger Consideration (the "Comparable M&A Transactions")
because of their focus on physical property measurement and the reasonable
comparability of their end markets. In reviewing and presenting this data, The
Beacon Group noted that the merger and acquisition transaction environment
varies over time because of macroeconomic factors, including interest rate and
equity market fluctuations, and microeconomic factors, including industry
results and growth expectations, that no transaction reviewed was identical to
the Merger and that, accordingly, an assessment of the results of the Comparable
M&A Transactions analysis necessarily involves considerations and judgments
concerning differences in financial and operating characteristics of Instron and
other factors that would affect the acquisition value of the companies to which
Instron was being compared.


     The Comparable M&A Transactions are:

<PAGE>   40

     With respect to the Comparable M&A Transactions and the Merger, The Beacon
Group, among other things, compared:

     - the Equity Consideration Value (as defined below) of the acquired
       companies and Instron as a multiple of LTM net income; and

     - the Aggregate Consideration Value (as defined below) of the acquired
       companies and Instron as a multiple of the LTM sales, EBITDA, EBIT and
       net book capital.

     The "Equity Consideration Value" of each acquired company and Instron was
calculated by multiplying the number of shares of common stock outstanding for
each company and Instron, respectively, by the aggregate consideration payable
per share of common stock in each Comparable M&A Transaction and in the Merger,
adjusted to include the impact, if any, of outstanding options. The "Aggregate
Consideration Value" of each acquired company and Instron was calculated by
adding the Equity Consideration Value of each company and Instron to the
company's and Instron's Net Debt, respectively.

     In order to adjust for different growth and market characteristics of the
Comparable M&A Transactions, The Beacon Group analyzed the mean and median
multiples for the Comparable M&A Transactions. The following table presents the
overall mean and median of the Equity Consideration Value as a multiple of net
income and the overall mean and median of Aggregate Consideration Value as a
multiple of sales, EBITDA, EBIT and net book capital for all of the Comparable
M&A Transactions and the multiples of the same financial metrics for Instron
based on the $22.00 per share Cash Merger Consideration.

     The Beacon Group calculated implied equity per share values for the Instron
Common Stock by using Instron's balance sheet as of December 31, 1998 (where
applicable) and by applying (1) the Aggregate Consideration Value to LTM EBITDA
multiples ranging from 7.2x to 7.9x, (2) the Aggregate Consideration Value to
LTM EBIT multiples ranging from 9.8x to 10.9x and (3) the Equity Consideration
Value to LTM net income multiples ranging from 12.7x to 16.3x, which in each
case were derived from the foregoing analysis, to the LTM EBITDA, LTM EBIT and
LTM net income, respectively, for Instron as of December 31, 1998.

     Discounted Cash Flow Analysis.  The Beacon Group performed a discounted
cash flow analysis of the projected unlevered free cash flows of Instron, which
is defined as cash flow available after changes in working capital, capital
spending and tax obligations for the period 1999 through 2003 using the terminal
multiple method. The Beacon Group based this analysis on the Instron
Projections, without any discounts or adjustments to those projections, and a
range of discount rates and terminal values to determine the theoretical present
value of the entire company.

     Applying discount rates ranging from 11.2% to 16.1% and terminal value
multiples of estimated Instron EBITDA in 2003 ranging from 6.5x to 8.0x, The
Beacon Group calculated the theoretical implied equity per share value of the
Instron Common Stock to range from $18.40 to $26.74. The Beacon Group arrived at
these discount rates based on its judgment of various factors, including
analysis of the estimated cost of capital and capital structures of selected
reasonably comparable public companies, and arrived at these terminal multiples
based on its review of the trading characteristics of the common stock of
selected reasonably comparable public companies and of reasonably comparable
acquisitions of selected companies.


     The Beacon Group noted that the Cash Merger Consideration was within the
range of implied equity per share values of Instron Common Stock produced by the
discounted cash flow analysis.



     The Beacon Group noted that a discounted cash flow analysis was generally
of more significance to a strategic buyer than a financial buyer such as
Kirtland or Bidder A. Strategic buyers often perform a discounted cash flow
analysis as part of their evaluation of a potential transaction, whereas
financial buyers generally focus on analyzing potential equity returns (and
their potential enhancement by using appropriate debt financing) rather than on
determining a company's theoretical present value. The Beacon Group also noted
the significant degree of dependency of the discounted cash flow analysis on the
estimated terminal value and, therefore, on the estimated Instron EBITDA for
2003.



     Leveraged Recapitalization Analysis.  The Beacon Group performed a
leveraged recapitalization analysis to determine the potential implied equity
value per share of Instron Common Stock that might be achieved in an acquisition
of Instron in a leveraged recapitalization transaction based on current market
conditions. In conducting this analysis, The Beacon Group utilized the Instron
Projections, without any discounts or adjustments to those projections, and
assumed that financing for the Merger could be obtained in the high yield and
bank finance markets in an amount not in excess of a certain multiple of the LTM
EBITDA and that a minimum internal rate of return ranging from 25% to 30% on
equity invested during a five year period would be required by the acquiror.
This analysis resulted in an estimated implied equity value per share of Instron
Common Stock on a leveraged recapitalization basis of approximately $20.50 to
$22.00. The Beacon Group noted that the Cash Merger Consideration equaled the
high point of the range of implied equity per share values of Instron Common
Stock produced by the leveraged transaction analysis.


     Implied Premium Analysis.  Using publicly available information, The Beacon
Group performed an analysis of premiums paid in selected acquisitions of
manufacturing companies with transaction values between $150 million and $250
million from January 1, 1993 to April 1, 1999. The Beacon Group calculated the
mean and median premiums as of the announcement dates in those transactions over
the stock prices one day, one week, and four weeks, respectively, prior to the
announcement dates. The following table sets forth information concerning the
mean and median premiums The Beacon Group calculated and the implied premium of
the Cash Merger Consideration over the closing price of the Instron Common Stock
one day, one week, and four weeks prior to April 30, 1999, respectively.

     The Beacon Group calculated implied equity per share values for Instron
ranging from $21.49 to $23.08 by applying the premiums derived in the foregoing
analysis to the respective Instron closing stock price one day, one week, and
four weeks prior to April 30, 1999. The Beacon Group noted that the $22.00 per
share Cash Merger Consideration was within the range of implied equity per share
values of Instron Common Stock produced by the implied premium analysis. The
Beacon Group also noted that the Cash Merger Consideration represents a premium
of 29.4% over Instron's closing stock price on April 30, 1999 and a premium of
6.7% over Instron's all-time high closing stock price of $20.63 on May 5, 1998.


     The information above is a brief summary of the material financial analyses
presented by The Beacon Group to the Instron Board on May 4, 1999. This summary
does not purport to be a complete description of the analyses performed by The
Beacon Group in connection with the rendering of the Beacon Opinion. The
preparation of a fairness opinion is a complex analytical process involving
various qualitative judgments as to the most appropriate and relevant methods of
financial analysis and the application of those methods to particular
circumstances and is not susceptible to partial analysis or summary description.
The Beacon Group believes that its analyses must be considered as a whole and
that selecting portions of its analyses, without considering all factors and
analyses, would create an incomplete view of the process underlying the Beacon
Opinion. In addition, The Beacon Group considered the significance and relevance
of the results of every portion of its analyses and did not assign relative
weights to any portion of its analyses, so that the ranges of valuations
resulting from any particular analysis described above should not be taken to be
The Beacon Group's view of the actual value of Instron.

     In performing its analyses, The Beacon Group made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Instron. The analyses
performed by The Beacon Group are not necessarily indicative of actual values,
trading values or actual future results that might be achieved, all of which may
be significantly more or less favorable than suggested by these analyses. No
public company utilized as a comparison is identical or directly comparable to
Instron, and none of the Comparable M&A Transactions or other business
combinations utilized as a comparison is identical or directly comparable to the
Merger and the other Transactions. Accordingly, a purely mathematical analysis
of publicly traded comparable companies and comparable business combinations
resulting from the Comparable Companies and Comparable M&A Transactions analyses
is not a meaningful method of using the relevant data; rather, these analyses
involve complex considerations and judgments concerning differences in financial
and operating characteristics and other factors that could affect the
transaction or the public trading or other values of the companies to which they
are being compared.


     In connection with its analyses, The Beacon Group utilized estimates and
forecasts of future operating results provided by the management of Instron,
including the Instron Projections. Analyses based on forecasts of future results
are not necessarily indicative of actual future results, which may be
significantly more or less favorable than suggested by the analyses. The
analyses are inherently subject to uncertainty, being based on numerous factors
or events beyond the control of Instron, and therefore future results or actual
values may be materially different from these forecasts or assumptions. The
analyses were prepared solely as part of The Beacon Group's analysis of the
fairness from a financial point of view of the consideration to be received by
the Public Stockholders pursuant to the Merger, and were provided to the Instron
Board in connection with the delivery of the Beacon Opinion. The Beacon Group's
analyses do not purport to be an appraisal or to reflect the prices at which a
company might actually be sold or the prices at which any securities may be
traded in the future. In addition, the Beacon Opinion was one of many factors
taken into consideration by the Instron Board in making its determination to
approve the Merger Agreement. Consequently, the analyses described above should
not be viewed as determinative of the opinion of either the Instron Board or
management of Instron with respect to the value of Instron or whether either the
Instron Board or management of Instron would have been willing to agree to
different terms for the Merger.


     Pursuant to an engagement letter, dated as of July 10, 1998, between
Instron and The Beacon Group, Instron agreed to pay The Beacon Group a fee of
$1,265,000, which includes a non-refundable retainer of $125,000, for services
rendered in connection with the Transactions. The fee (less the $125,000
retainer, which has already been paid to The Beacon Group) will be payable at
the closing of the Merger. Instron has
                                       32
<PAGE>   43

also agreed to reimburse The Beacon Group for its reasonable out-of-pocket
expenses, including travel and assorted other expenses, and to indemnify The
Beacon Group and certain of its affiliates against certain liabilities in
connection with their engagement, including liabilities under the federal
securities laws.

     The Instron Board retained the Beacon Group on the basis of its experience
and expertise. As part of its strategic advisory business, The Beacon Group
engages in the valuation of businesses and their securities in connection with
mergers and acquisitions, financings, private placements, principal investments
and other purposes. The Beacon Group participated in some of the negotiations
relating to the Merger Agreement and the Transactions.

PURPOSE AND REASONS OF THE INVESTOR GROUP FOR THE MERGER

     The purpose of the Investor Group for engaging in the Transactions is to
acquire 100% ownership of Instron. The members of the Investor Group regard the
acquisition of Instron as an attractive investment opportunity because they
believe that Instron's future business prospects are favorable and that the
substantial increase in the debt to equity ratio of Instron after the Merger,
although resulting in greater investment risks, will create the potential for
the shareholders' equity value of Instron to increase more rapidly on a
percentage basis than the shareholders' equity value of an identical corporation
having a larger equity base and less debt. While the members of the Investor
Group are looking to achieve substantial returns on their investment in Instron,
they believe that such returns are available only to those investors like
themselves who are willing to bear the substantial risks associated with a
highly leveraged investment. The members of the Investor Group also believe that
by acquiring 100% ownership of Instron and operating Instron as a privately held
company, they will be able to more closely and directly monitor and influence
the performance of their investment. The Equity Investor also believes that
Instron's future business prospects can be improved through its active
participation with Instron's management in the strategic direction and
operations of Instron.

     The Equity Investor's assessment of the risks and benefits of the Merger
and the other Transactions is based upon publicly available information
regarding Instron, the Equity Investor's due diligence investigation of Instron,
and the Equity Investor's experience in investing in similarly situated
companies. The proposed acquisition of Instron by the Investor Group has been
structured as a merger in order to, among other things, provide for the
redemption of the Instron Common Stock held by the Public Stockholders in
connection with the transfer of the ownership of Instron from the current
stockholders to the Investor Group, to facilitate the required financing for the
Transactions, and to preserve Instron's corporate identity. The Investor Group
did not consider any alternative transaction structure other than an acquisition
of Instron pursuant to the terms of the Merger Agreement. While the Investor
Group believes that there will be significant opportunities associated with its
investment in Instron, there are also substantial risks that such opportunities
may not be fully realized.


     The exact amount of the Equity Investor's investment in MergerCo is
dependent upon the level of Net Indebtedness of Instron as of the closing date
of the Merger. At April 3, 1999, Instron's Net Indebtedness was approximately
$3.9 million. In the event that Instron's Net Indebtedness is greater than $3.9
million at the Effective Time, the Equity Investor will be required to increase
its investment in MergerCo resulting in the Equity Investor receiving more
shares of Surviving Corporation Common Stock in the Merger and its relative
ownership percentage in the Surviving Corporation being higher. In the
alternative, if Instron's Net Indebtedness at the Effective Time is less than
$3.9 million, then the Equity Investor will decrease its investment in MergerCo
resulting in the Equity Investor receiving fewer shares of Surviving Corporation
Common Stock in the Merger and its relative ownership percentage in the
Surviving Corporation being lower. Based upon a level of Net Indebtedness of
$3.9 million, as a result of the Merger the Equity Investor will acquire, for an
investment of approximately $49.6 million, approximately 87.4% of the
outstanding shares of Surviving Corporation Common Stock; the Other Investors
will acquire, following the exchange of 160,000 shares of Instron Common Stock
with a value of $22.00 per share, or approximately $3.5 million in the
aggregate, approximately 6.2% of the outstanding shares of Surviving Corporation
Common Stock; and the Management Investors will acquire, following the exchange
of 165,210 shares of Instron Common Stock with a value of $22.00 per share, or
approximately $3.6 million in the aggregate, approximately 6.4% of the
outstanding shares of Surviving Corporation Common Stock. Each member of the
Investor Group will receive

                                       33
<PAGE>   44


one share of Surviving Corporation Common Stock for each $110 of value invested
in the Surviving Corporation, which equates to one share of Surviving
Corporation Common Stock for five shares of Instron Common Stock. The Management
Investors also will receive the Rollover Options and additional options to
purchase shares of Instron Common Stock granted pursuant to a stock option plan
to be adopted by the Surviving Corporation upon consummation of the Merger which
will represent, in the aggregate, 8.7% of the outstanding shares of Surviving
Corporation Common Stock on a fully diluted basis (assuming the exercise of all
Rollover Options and newly granted options). The exchange by the Other Investors
and the Management Investors of a portion of their equity interest in Instron
Common Stock (including a portion of their outstanding stock options) for an
equity interest in the Surviving Corporation Common Stock will, among other
things, enable the Merger to be accounted for as a recapitalization for
accounting purposes. The Other Investors and the Management Investors also will
receive the Cash Merger Consideration for the remainder of their investment in
Instron on the same terms as the Public Stockholders and, with respect to the
remainder of their outstanding stock options, will receive a cash payment equal
to the difference between the Cash Merger Consideration and the exercise price
for such options. The number of shares of Instron Common Stock held by the
Management Investors being exchanged for shares of Surviving Corporation Common
Stock and not being converted into the right to receive the Cash Merger
Consideration was determined through arms-length negotiations between Kirtland
and the Management Investors and reflects Kirtland's desire that the Management
Investors have a significant equity participation in the Surviving Corporation.
The number of shares of Instron Common Stock held by the Other Investors being
exchanged for shares of Surviving Corporation Common Stock and not being
converted into the right to receive the Cash Merger Consideration was determined
through arms-length negotiations between Kirtland and the Other Investors and
reflects a level of equity participation by the Other Investors which, in the
opinion of Kirtland, enables the Merger to be accounted for as a
recapitalization for accounting purposes.


POSITION OF THE INVESTOR GROUP AS TO FAIRNESS OF THE MERGER


     Each member of the Investor Group has considered the analyses and findings
of the Special Committee and the Instron Board (described in detail in "-- The
Special Committee's and the Instron Board's Recommendation") with respect to the
fairness of the Merger to the Public Stockholders based upon (i) the reasons set
forth under "-- The Special Committee's and the Instron Board's Recommendation,"
which were made known to the Equity Investor subsequent to the Special
Committee's and the Instron Board's determination that the Merger Agreement and
the Transactions were fair to and in the best interests of the Instron
stockholders, (ii) the Equity Investor's review of publicly available
information regarding Instron, (iii) the Equity Investor's due diligence
investigation of Instron, and (iv) the Other Investors' and the Management
Investors' understanding of and familiarity with Instron's business. Each member
of the Investor Group has adopted the analyses and findings of the Special
Committee and the Instron Board with respect to the fairness of the Merger and
believes that the Merger Agreement, the Merger and the other Transactions are
fair to and in the best interests of the Public Stockholders; provided that no
opinion is expressed as to the fairness to any stockholder making an investment
in the Surviving Corporation. No member of the Investor Group makes any
recommendation as to how the stockholders of Instron should vote on the Merger
Agreement. The Investor Group has financial interests in the Merger and the
Other Investors and the Management Investors have financial and other interests
in the Merger. See "-- Conflicts of Interest."


CONFLICTS OF INTEREST

     In considering the recommendations of the Instron Board and the Special
Committee with respect to the Merger, you should be aware that the Management
Investors and the Other Investors, have interests in connection with the Merger
which may present them with actual or potential conflicts of interest as
summarized below. The Instron Board and the Special Committee were aware of
these interests and considered them among the other matters described under
"-- The Special Committee's and the Instron Board's Recommendation." The Instron
Board and the Special Committee generally considered the Other Investors' and
the Management Investors' conflicts of interest to be a negative factor in their
respective determinations that the Merger is fair and in the best interests of
the Public Stockholders. In particular, the Instron Board and the Special
Committee considered the fact that consummation of the Merger would
                                       34
<PAGE>   45

preclude the Public Stockholders from having the opportunity to participate in
the future growth prospects of Instron. In addition, the Instron Board and the
Special Committee recognized that the Management Investors and the Other
Investors will have the opportunity to benefit from any increases in the value
of Instron following the Merger by reason of their continuing equity interest in
the Surviving Corporation and therefore may realize a substantial economic
benefit from the transaction.

     Post-Merger Ownership and Control of the Surviving Corporation. It is
anticipated that immediately after the Merger the following individuals and
entities will beneficially own the number of shares of Surviving Corporation
Common Stock shown in the following table.

     Following consummation of the Merger, it is expected that those Management
Investors who were members of Instron's management prior to the Merger will
continue as management of the Surviving Corporation. The Board of Directors of
the Surviving Corporation following the Merger will be comprised of Mr.
McConnell, one person designated by Mr. McConnell, and at least three persons
designated by Kirtland.

     The Other Investors. The Other Investors have also agreed with Kirtland to
maintain an equity ownership position in Instron following the completion of the
Merger. To that end, the Other Investors will exchange an aggregate of 160,000
shares of Instron Common Stock for an aggregate of 32,000 shares of Series B
Preferred Stock immediately prior to the Effective Time. Such shares of Series B
Preferred Stock will be converted at the Effective Time into a like number of
shares of Surviving Corporation Common Stock in the Merger. Upon consummation of
the Transactions, the Other Investors will own approximately 6.2% of the
outstanding shares of Surviving Corporation Common Stock.


     The Management Investors. The Management Investors have agreed with
Kirtland to maintain an equity ownership position in Instron following the
completion of the Merger. To that end, certain of the Management Investors will
exchange an aggregate of 165,210 shares of Instron Common Stock for an aggregate
of 33,042 shares of Series B Preferred Stock immediately prior to the Effective
Time. Such shares of Series B Preferred Stock will be converted at the Effective
Time into a like number of shares of Surviving Corporation Common Stock in the
Merger. Of the 165,210 shares of Instron Common Stock to be exchanged for shares
of Series B Preferred Stock, an aggregate of 25,340 shares representing shares
of restricted Instron Common Stock previously issued to certain Management
Investors will be exchanged for 5,068 shares of Series B Preferred Stock. Such
shares of Series B Preferred Stock will be converted at the Effective Time into
a like number of shares of restricted Surviving Corporation Common Stock. These
shares of restricted stock will be governed by the Instron Corporation 1992
Stock Incentive Plan (as such plan is amended as of the Effective Time) (the
"1992 Plan") and certain amended restricted stock award agreements (the
"Restricted Stock Award Agreements"). The Restricted Stock Award Agreements
amend the prior agreements by (i) providing for vesting of the shares subject
thereto on May 14, 2004 or earlier in the event certain financial results are
achieved by the Surviving Corporation and (ii) revising part of the definitions
of "cause" and "good reason". Upon consummation of the Transactions, the
Management Investors will own approximately 6.4% of the outstanding shares of
Surviving Corporation Common Stock.


     In addition, options to purchase up to an aggregate of 125,000 shares of
Instron Common Stock held by certain Management Investors will be assumed by the
Surviving Corporation and converted into the Rollover Options to purchase up to
an aggregate of 25,000 shares of Surviving Corporation Common Stock. The
Rollover Options will be governed by the 1992 Plan and certain amended stock
option agreements (the "Stock Option Agreements"). Each Rollover Option will be
fully vested and exercisable upon the consummation of the Merger. The Rollover
Options will represent approximately 4.6% of the Surviving Corporation Common
Stock on a fully diluted basis (assuming the exercise of all Rollover Options)
immediately following the Effective Time.

     Cash Payments to the Other Investors and the Management Investors. The
Other Investors and the Management Investors also will participate in the Merger
as Public Stockholders to the extent that they hold shares of Instron Common
Stock that are not ultimately converted into Surviving Corporation Common Stock,
or hold outstanding options to purchase shares of Instron Common Stock that are
not converted into Rollover Options. In the Merger, the Other Investors and the
Management Investors will be entitled to receive the Cash Merger Consideration
for their unconverted shares of Instron Common Stock. Certain of the Management
Investors also own shares of restricted Instron Common Stock for which they will
be entitled to receive the Cash Merger Consideration in the Merger. They also
will be entitled to receive cash based on the number of shares of Instron Common
Stock underlying their unconverted stock options and the difference between the
applicable per share exercise price of such options and the Cash Merger
Consideration. See "The Merger -- Cash-Out of Instron Stock Options."

     The following table sets forth information as of the date of this Proxy
Statement as to the shares of Instron Common Stock owned of record by the Other
Investors and the shares of Instron Common Stock and the options to purchase
shares of Instron Common Stock held by the Management Investors for which cash
payments will be received upon consummation of the Merger.

     Grant of New Options to the Management Investors. At the Effective Time,
Instron will adopt the Instron Corporation 1999 Stock Option Plan (the "1999
Plan") and reserve for issuance under the plan such number of shares of
Surviving Corporation Common Stock equal to 10% of the aggregate number of
shares of Surviving Corporation Common Stock outstanding on a fully diluted
basis immediately following the Effective Time (the "Available Shares"). At the
Effective Time, the Surviving Corporation will grant to the ten Management
Investors who were members of Instron's management prior to the Merger, options
to purchase, in the aggregate, up to such number of shares of Surviving
Corporation Common Stock equal to 40% of the Available Shares. Each such
Management Investor will receive a grant equal to 3.33% of the Available Shares,
other than Mr. McConnell who will receive a grant equal to 9.99% of the
Available Shares. The options will be incentive stock options intending to
qualifying under Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code"), up to the limitations set forth in the Code, and non-qualified
stock options to the extent of the excess over such limitations. Each option
will be exercisable at the fair market value per share determined in good faith
by the Board of Directors of the Surviving Corporation (estimated to be $110.00
per share at the Effective Time), and will be exercisable to the extent of
one-fifth of the shares on each of the first five anniversaries of the date of
grant for so long as the optionee is in the continuous employ of the Surviving
Corporation. Unexercisable options will be forfeited upon termination of
employment. Upon a change in control of the Surviving Corporation, all options
will become immediately exercisable in full. Options will be exercisable in
cash, or by surrender of Surviving Corporation Common Stock owned by the
optionee. Each option will terminate three months after the optionee ceases to
be an employee of the Surviving Corporation or a subsidiary for any reason other
than death or disability, or six months after the optionee ceases to be an
employee as a result of death or disability, and in no event more than ten years
from the date of grant. Non-qualified stock options will be transferable to
members of an optionee's immediate family (including trusts and partnerships
established for the benefit of the optionee and his immediate family).


     Confidentiality and Noncompetition Agreements with the Management
Investors. In order to induce Kirtland to enter into the Merger, at the
Effective Time each of the Management Investors who will continue as a member of
Instron's management after the Merger will enter into a Confidentiality and
Noncompetition

                                       38
<PAGE>   49

Agreement with Instron. Under the agreement, each such Management Investor will
maintain confidentiality of trade secrets, customer lists and other confidential
business information of Instron and its subsidiaries, and will not engage in
Competition (as such term is defined in the Confidentiality and Noncompetition
Agreement) for so long as he is employed with Instron or any of its subsidiaries
and thereafter until the first anniversary of the date on which he last worked
for Instron.


     Severance Agreements with the Management Investors. Each Management
Investor (other than Mr. McConnell) with an Executive Severance Agreement has
agreed to amend such agreement as of the Effective Time. Each such Management
Investor had entered into his Executive Severance Agreement on May 14, 1998 and
had not entered into any amendments thereto. The amendment modifies the
definition of good reason in the Executive Severance Agreement. The Executive
Severance Agreements currently provide that the termination by an executive of
such executive's employment with Instron for "good reason" will entitle the
executive to receive certain severance compensation and benefits. The amendment
revises part of the definition of "good reason". As amended, the Executive
Severance Agreement will provide that the termination by an executive of such
executive's employment with Instron constitutes "good reason" if the Surviving
Corporation fails to maintain the executive in an executive position with duties
and responsibilities in the aggregate normally associated with an executive at
the Surviving Corporation at a vice president level or higher, or if the
executive's title is reduced to below a vice president or, except for John R.
Barrett, the executive is no longer a member of the Executive Committee of the
Surviving Corporation. The amended Executive Severance Agreement will not apply
to any termination of employment that occurs after the second anniversary of the
Effective Time, or to any change in control that occurs after the Effective
Time.



     Deferred Compensation Agreement with James M. McConnell. At the Effective
Time, the Surviving Corporation and Mr. McConnell will enter into a Deferred
Compensation Agreement to replace severance compensation and benefits otherwise
payable to Mr. McConnell under his existing Executive Severance Agreement which
had been entered into by Mr. McConnell on May 14, 1998. Pursuant to such
agreement, the Surviving Corporation will credit $1,200,000 to a nonforfeitable
deferred compensation account for Mr. McConnell. The Surviving Corporation will
credit interest on the value of the account in arrears on the last business day
of each quarter at a rate of interest equal to the composite "prime rate" as
quoted in the Eastern Edition of the Wall Street Journal for that day. The
account will be paid to Mr. McConnell in five annual installments commencing on
the fifth anniversary of the Effective Time; provided that commencement of
payments will be accelerated in the event of Mr. McConnell's disability, death
or termination without cause. In addition, upon a change in control of the
Surviving Corporation, the account will be paid to Mr. McConnell in a lump sum.


     In the event that any amount to be paid under the Deferred Compensation
Agreement would be an "excess parachute payment" within the meaning of the Code,
then the Surviving Corporation may propose that the payments to be made under
the agreement be reduced to the minimum extent necessary so that no portion of
such payment, if so reduced, constitutes an excess parachute payment. If Mr.
McConnell agrees to any such reduction, interest credited to the account will be
reduced to the minimum extent necessary so that no portion of such interest to
be paid, as so reduced, constitutes an excess parachute payment. If Mr.
McConnell does not agree to such reduction, then the Surviving Corporation may
accelerate payments to Mr. McConnell to the extent required so that no payment
to Mr. McConnell under the agreement will constitute an excess parachute
payment. Mr. McConnell is entitled to receive in the same manner as provided in
Mr. McConnell's Executive Severance Agreement an additional "gross-up payment"
to the extent necessary to offset any federal, state and local income tax,
employment tax and excise tax upon the excess parachute payment.

     Voting Agreement. Pursuant to a Voting Agreement dated as of May 6, 1999
(the "Voting Agreement"), the Other Investors and certain of their affiliates
and the Management Investors and certain of their affiliates agreed with
MergerCo to vote (or cause to be voted) at the Special Meeting all of the shares
of Instron Common Stock (the "Voting Shares") owned by them in favor of the
proposal to approve the Merger Agreement and the Transactions. The Other
Investors and certain of their affiliates and the Management Investors and
certain of their affiliates also agreed (i) not to sell, tender, transfer,
pledge, encumber, assign or

                                       39
<PAGE>   50

otherwise dispose of any Voting Shares, or deposit any Voting Shares into a
voting trust or enter into a voting agreement or arrangement with respect to
voting any Voting Shares, or grant any proxy or power of attorney with respect
thereto, (ii) to waive their appraisal rights with respect to the Voting Shares,
and (iii) at the request of Kirtland, to take further lawful actions as may be
necessary or desirable to consummate and make effective the transactions
contemplated by the Voting Agreement. The Voting Shares represent approximately
22.4% of the outstanding shares of Instron Common Stock.

     The Voting Agreement will terminate upon the earlier of the consummation of
the Merger or the termination of the Merger Agreement without consummation of
the Merger.

     Stockholders Agreement. Upon consummation of the Merger, members of the
Investor Group will enter into the Stockholders Agreement. The Stockholders
Agreement provides that the stockholders of the Surviving Corporation may not
transfer their shares of Surviving Corporation Common Stock except under certain
circumstances. Under the Stockholders Agreement, the Surviving Corporation has a
right of first refusal in the event that an Other Investor or a Management
Investor wishes to sell shares of Surviving Corporation Common Stock, or, in the
event that the Surviving Corporation does not exercise its right of first
refusal, the nontransferring stockholders (other than any management stockholder
who is no longer an employee of the Surviving Corporation) will have the
opportunity to purchase such shares. The Stockholders Agreement also provides
that the Other Investors and the Management Investors will have the opportunity
to participate in certain sales of Surviving Corporation Common Stock by the
Equity Investor, and the Equity Investor has the right to cause the Other
Investors and the Management Investors to participate in certain such sales. In
addition, the Stockholders Agreement provides for certain "puts" and "calls"
upon the termination of a Management Investor's employment with the Surviving
Corporation.


     Registration Rights Agreement. Upon consummation of the Merger, the Equity
Investor, the Other Investors, the Management Investors and the Surviving
Corporation will enter into the Registration Rights Agreement, pursuant to which
the Other Investors and the Management Investors will have the right to
participate, or "piggy-back," in equity offerings initiated by the Surviving
Corporation that are registered under the Securities Act, subject, in the case
of the Management Investors, to the approval of the underwriters involved with
any such equity offering and other customary terms and conditions. In the event
that the Equity Investor, in connection with a future business strategy,
considers a public offering of Surviving Corporation Common Stock, these
registration rights could provide the Other Investors and the Management
Investors with a means by which to achieve liquidity for their investments.


     The foregoing summaries of the Confidentiality and Noncompetition
Agreements, the amendment to the Executive Severance Agreements, the Deferred
Compensation Agreement, the Voting Agreement, the Stockholders Agreement and the
Registration Rights Agreement are qualified in their entirety by reference to
the actual terms of such agreements, which are filed as exhibits to Instron's
Schedule 13E-3.

     Fees and Expenses. Instron has agreed to pay for the reasonable fees and
expenses of the Other Investors' legal counsel up to an aggregate of $40,000.
Instron has also agreed to pay for the reasonable fees and expenses of the
Management Investors' legal counsel up to an aggregate of $85,000.

     Indemnification and Insurance. Under the Merger Agreement, Instron will
indemnify and hold harmless any former or current director, officer, employee,
fiduciary or agent of Instron or any of its subsidiaries, and after the
Effective Time, the Surviving Corporation will indemnify and hold harmless, as
and to the full extent permitted by applicable law, each such indemnified party
against any losses, in connection with any threatened or actual claim, action,
suit, proceeding or investigation, based in whole or in part on, or arising in
whole or in part out of, or pertaining to (i) the fact that he is or was a
director, officer, employee, fiduciary or agent of Instron or any of its
subsidiaries, or is or was serving at the request of Instron or any of its
subsidiaries as a director, officer, employee, fiduciary or agent of another
corporation, partnership, joint venture, trust or other enterprise, or (ii) the
negotiation, execution or performance of the Merger Agreement or any of the
Transactions (whether asserted or arising before or after the Effective Time).
The parties also agree that all rights to indemnification existing in favor of,
and all limitations on the personal liability of, the directors, officers,
employees and agents of Instron and its subsidiaries provided for in Instron's
Restated

                                       40
<PAGE>   51

Articles of Organization or Bylaws as in effect as of the date of the Merger
Agreement with respect to matters occurring prior to the Effective Time, and
including the Merger and the Transactions, shall continue in full force and
effect for a period of six years from the Effective Time.

     Prior to the Effective Time, Instron will purchase an extended reporting
period endorsement under its existing directors' and officers' liability
insurance coverage for Instron's directors and officers which shall provide such
directors and officers with coverage at least as favorable as the current policy
for six years following the Effective Time. It is anticipated that the total
aggregate cost of such coverage will be approximately $160,000.


     The Beacon Group. The Beacon Group served as financial advisor to the
Instron Board and the Special Committee. Two of the thirteen managing directors
of The Beacon Group are limited partner investors in Kirtland. The Instron
Board, the Special Committee and The Beacon Group believe that the foregoing
relationships do not affect The Beacon Group's ability to act independently and
impartially as financial advisor to the Instron Board and the Special Committee.
The Instron Board and the Special Committee also considered the fact that two of
the thirteen managing directors of The Beacon Group were limited partner
investors in Kirtland, one of whom was actively involved in advising the Instron
Board and the Special Committee during the bidding process. However, the Instron
Board and the Special Committee noted that these individuals were passive
investors in Kirtland who together owned an approximately 0.12% limited partner
interest in Kirtland and did not control in any way the actions of Kirtland.
Moreover, two other senior professionals of The Beacon Group with no economic
interest in Kirtland were actively involved in advising the Instron Board and
the Special Committee during the bidding process. In addition, the Instron Board
and the Special Committee noted that under the terms of The Beacon Group's
engagement with Instron, The Beacon Group's percentage fee would increase as the
price to be paid to the Public Stockholders in any transaction increased.
Accordingly, the Instron Board and the Special Committee believed that despite
the economic interest in Kirtland held by the two managing directors of The
Beacon Group, the terms of The Beacon Group's engagement provided a
substantially greater economic incentive to assist Instron in obtaining the
highest price for the stockholders in any transaction. In view of the foregoing,
the Instron Board and the Special Committee concluded that the aforementioned
relationship between the two managing directors of The Beacon Group and Kirtland
would not affect The Beacon Group's ability to act independently and impartially
as financial advisor to the Instron Board and the Special Committee.


     Special Committee. The members of the Special Committee will be treated in
the Merger as Public Stockholders with respect to their shares of Instron Common
Stock. Mr. Young owns 25,000 shares of Instron Common Stock and Mr. Moore owns
2,500 shares of Instron Common Stock. The third member of the Special Committee,
Mr. Smith, does not own any shares of Instron Common Stock. None of the members
of the Special Committee hold any options to purchase Instron Common Stock. Upon
consummation of the Merger, Mr. Young will be entitled to receive $550,000 as
Cash Merger Consideration for his shares of Instron Common Stock and Mr. Moore
will be entitled to receive $55,000 as Cash Merger Consideration for his shares
of Instron Common Stock.

     The members of the Special Committee, which held five meetings from March
1999 through the date of this Proxy Statement, will receive compensation from
Instron in connection with these committee meetings. In connection with
establishing the Special Committee, the Instron Board approved the payment of a
one-time fee of $7,500 for, and an amount equal to $1,200 for each meeting of
the Special Committee attended by, Mr. Young, the Chairman of the Special
Committee. Mr. Young received from Instron an aggregate of $13,500 as
compensation for serving as the chairman of the Special Committee. The Instron
Board also approved the payment of a one-time fee of $5,000 for, and an amount
equal to $700 for each meeting of the Special Committee attended by, each of
Messrs. Moore and Smith. Messrs. Moore and Smith each received from Instron an
aggregate of $8,500 as compensation for serving on the Special Committee.

     Members of the Special Committee will be entitled to certain
indemnification rights and to directors' and officers' liability insurance which
will be continued by Instron following the Merger as described above for the
current and former officers and directors of Instron.

                                       41
<PAGE>   52

     The Instron Board and the Special Committee believe that the foregoing
arrangements do not affect the Special Committee's independence or impartiality.

CERTAIN EFFECTS OF THE MERGER

     As a result of the Merger, the entire equity interest in Instron as the
Surviving Corporation will be owned by the Investor Group. The Public
Stockholders will no longer have any interest in, and will not be stockholders
of, Instron, and, therefore, will not participate in Instron's future earnings
and potential growth. Instead, the Public Stockholders will have the right to
receive $22.00 in cash, without interest, for each share of Instron Common Stock
held by them immediately prior to the Effective Time (other than shares in
respect of which appraisal rights have been perfected). An equity investment in
Instron as the Surviving Corporation in the Merger involves substantial risk,
including risks resulting from the limited liquidity of an investment in the
common stock of Instron as a privately held company and risks resulting from
Instron's increased leverage in connection with the financing of the
Transactions. Nonetheless, if Instron successfully executes its business
strategy, the value of such an equity investment could be considerably greater
than the original cost thereof. See " -- Conflicts of Interest" and "Cautionary
Statement Concerning Forward-Looking Information."

     Following the Merger, Instron intends to delist the Instron Common Stock
from AMEX. The Surviving Corporation does not intend to apply to have the
Surviving Corporation Common Stock listed on any national securities exchange or
automated quotation system. The registration of Instron Common Stock under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), will terminate
in connection with the Merger.

FINANCING OF THE MERGER

     Generally. It is estimated that an aggregate of approximately $174.2
million will be required to consummate the Transactions and pay related fees and
expenses. These funds are expected to come from the following sources:

     - an equity investment made by the Equity Investor of approximately $49.6
       million, assuming a Net Indebtedness of $3.9 million;

     - borrowings by the Surviving Corporation of approximately $14.0 million
       under the Credit Facility;

     - borrowings by the Surviving Corporation of approximately $100.0 million
       from the issuance of debt instruments; and

     - Instron's available cash reserves which, as of April 3, 1999, were
       approximately $10.6 million.


     Debt Instruments. Kirtland currently anticipates that $100.0 million of the
funds necessary to consummate the Transactions will be raised through the
issuance of debt instruments by Instron in the private or public capital
markets. However, in the event that Kirtland is unable to arrange for such debt
financing, Kirtland has obtained the DLJ Bridge Letter pursuant to which DLJ
Bridge has committed to purchase from Instron $100.0 million in principal amount
of Bridge Notes. If issued by Instron and purchased by DLJ Bridge, it is
anticipated that the Bridge Notes would have the following features: (i)
subordinated to Instron's senior credit facility (which National City Bank has
committed to provide in connection with the Merger); (ii) a term of six and
one-half years, subject to certain conditions; (iii) guaranteed by Instron and
its subsidiaries if such entity is a guarantor of Instron's senior credit
facility; (iv) interest paid quarterly at a fluctuating rate not to exceed 17%
and not to be less than 10%; (v) registration and resale rights with respect to
the Bridge Notes; and (vi) mandatory redemption upon Instron's issuance of debt
or equity or certain asset sales, in any case resulting in proceeds in excess of
the amount required to be paid under Instron's senior credit facility. It also
is anticipated that the Bridge Notes would contain covenants that are customary
for this type of financing including restrictions on indebtedness, dividends,
liens, affiliate transactions, stock repurchases, asset sales and mergers.


     Revolving Credit Facility. Kirtland also has received the National City
Letter in which National City Bank has committed to provide Instron with the
Credit Facility in connection with the Merger. It is expected that the Credit
Facility will have the following features: (i) maximum availability of $50.0
million subject to sublimits for the issuance of standby letters of credit and
borrowings denominated in a liquid currency other

                                       42
<PAGE>   53


than U.S. dollars; (ii) six-year term; (iii) collateralized by receivables,
inventory, equipment and other assets and a first priority lien on 100% of the
common stock of Instron's domestic subsidiaries and 65% of the common stock of
Instron's foreign subsidiaries; (iv) interest at alternative fluctuating rates,
as selected by Instron, of either a prime rate or the federal funds rate plus
0.5%, or a LIBOR rate, in each case plus an applicable margin; (v) required
payment of various commitment and other fees; and (vi) customary financial and
other representations and warranties and covenants. The availability of the
credit contemplated by the National City Letter is dependent upon satisfaction
of a number of conditions, including delivery of all required documentation,
consummation of the Merger and other Transactions, receipt of all required
regulatory approvals, and there not having been any material litigation
involving Instron nor any material adverse change in the financial condition or
business of Instron. Kirtland and Instron do not believe that the Class Action
Complaint described under the heading "Legal Proceedings" will affect the
availability of the Credit Facility. At the closing of the Merger, approximately
$14.0 million will be used to finance the consummation of the Transactions.
Undrawn amounts under the Credit Facility will be available to support working
capital needs and general corporate purposes.


     The foregoing is only a summary of the National City Letter and is
qualified in its entirety by reference to the actual terms of the National City
Letter, which is filed as an exhibit to Instron's Schedule 13E-3.

     The definitive agreements for the issuance and sale of the debt securities
and the Credit Facility have not been negotiated and completed. Accordingly, the
terms of such arrangements described above may change as a result of the
negotiation of definitive agreements. In addition, the obligation of National
City Bank to provide its respective financing is subject to the satisfaction of
numerous conditions including, without limitation, the condition that no
material adverse change in the business, assets, condition (financial or
otherwise) or results of operations of Instron and its subsidiaries taken as a
whole shall have occurred and that there shall not have occurred any event or
other circumstance which would, individually or in the aggregate, reasonably be
expected to result in any such material adverse change prior to the Effective
Time.

CONDUCT OF INSTRON'S BUSINESS AFTER THE MERGER

     Instron designs, develops, manufactures, markets, and services materials
and structural testing systems, software, and accessories. These products are
used principally in research and development and quality control applications to
test the mechanical properties of various materials, components, and structures.
The materials tested include metals, plastics, textiles, composites, ceramics
and rubber. Instron systems test virtually all natural and man-made materials
from fragile fibers to the exotic materials needed for space exploration.

     The Investor Group is continuing to evaluate Instron's business, practices,
operations, properties, corporate structure, capitalization, management, and
personnel and will determine what changes, if any, will be desirable. Such
changes may include, without limitation, entering into an extraordinary
corporate transaction, a sale of assets, a change in the composition of the
Instron Board, or a change in Instron's dividend policy. Subject to the
foregoing, the Investor Group expects that the day-to-day business and
operations of Instron will be conducted substantially as they are currently
being conducted by Instron.

     It is expected that the Management Investors who are members of Instron's
management prior to the Merger will remain as management of the Surviving
Corporation. Such Management Investors, other than John R. Barrett, will also
serve on the Executive Committee of the Surviving Corporation. The Investor
Group does not currently contemplate any material change in the composition of
management or personnel. The Board of Directors of the Surviving Corporation
will be comprised of Mr. McConnell, one person designated by Mr. McConnell, and
at least three persons designated by Kirtland.

                              THE SPECIAL MEETING

DATE, TIME, AND PLACE OF THE SPECIAL MEETING


     The Special Meeting will be held on August 17, 1999, at 10:00 a.m., local
time, at the Hilton Dedham Place, 25 Allied Drive, Dedham, Massachusetts 02026.


PROXY SOLICITATION


     This Proxy Statement is being solicited by the Instron Board. All expenses
incurred in connection with solicitation of the enclosed proxy will be paid by
Instron. Officers, directors, and regular employees of Instron, who will receive
no additional compensation for their services, may solicit proxies by telephone
or personal call. In addition, Instron has retained MacKenzie Partners, Inc. to
solicit proxies for a fee of $5,500 plus expenses. Instron has requested brokers
and nominees who hold stock in their names to furnish this proxy material to
their customers, and Instron will reimburse such brokers and nominees for their
related out-of-pocket expenses. This Proxy Statement and the accompanying proxy
card are being mailed to stockholders on or about July 15, 1999.


MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING


     At the Special Meeting, Instron stockholders will be asked to consider and
vote upon a proposal to approve the Merger Agreement and the Transactions,
including the Merger. A copy of the Merger Agreement is attached as Appendix A
to this Proxy Statement.


RECORD DATE AND QUORUM REQUIREMENT


     Instron Common Stock was the only class of voting security of Instron
outstanding as of the Record Date. The Instron Board has fixed the close of
business on July 12, 1999 as the Record Date for the determination of
stockholders entitled to notice of, and to vote at, the Special Meeting. Each
holder of record of Instron Common Stock at the close of business on the Record
Date is entitled to one vote for each share then held on each matter submitted
to a vote of stockholders. At the close of business on the Record Date, there
were 6,978,448 shares of Instron Common Stock issued and outstanding held by
approximately 417 holders of record.


     The holders of a majority of the outstanding shares entitled to vote at the
Special Meeting must be present in person or represented by proxy to constitute
a quorum for the transaction of business. Abstentions are counted for purposes
of determining the presence or absence of a quorum for the transaction of
business.

VOTING PROCEDURES


     Pursuant to the MBCL, approval of the Merger Agreement, which is attached
as Appendix A hereto, and the Transactions, including the Merger, will require
the affirmative vote of the holders of two-thirds of the outstanding shares of
Instron Common Stock entitled to vote at the Special Meeting. A failure to vote
or a vote to abstain will have the same legal effect as a vote cast against
approval of the Merger Agreement and the Transactions. Brokers and, in many
cases, nominees will not have discretionary power to vote on the proposal to be
presented at the Special Meeting. Accordingly, beneficial owners of shares
should instruct their brokers or nominees how to vote. A broker non-vote will
have the same effect as a vote against the Merger.


     If there are insufficient votes to approve the Merger Agreement and the
Transactions at the Special Meeting, proxies voted in favor of approval of the
Merger Agreement and the Transactions and proxies as to which no voting
instructions are given may be voted to adjourn the Special Meeting in order to
solicit additional proxies in favor of approval of the Merger Agreement and the
Transactions. If the Special Meeting is adjourned for any purpose, at any
subsequent reconvening of the Special Meeting, all proxies will be voted in the
same manner as such proxies would have been voted at the original convening of
the meeting (except for any proxies which have been revoked or withdrawn),
notwithstanding that they may have been voted on the same or any other matter at
a previous meeting.

                                       44
<PAGE>   55

     The Merger was not structured so that approval of at least a majority of
Instron stockholders not affiliated with Instron or the Investor Group is
required in order to consummate the Merger.

     Any stockholder of Instron has the right to dissent from approval of the
Merger Agreement and the Transactions and, subject to strict compliance with
certain requirements and procedures set forth in Sections 85 to 98, inclusive,
of the MBCL, to receive payment of the "fair value," as defined in the MBCL, of
his or her shares of Instron Common Stock. See "Appraisal Rights."

VOTING AND REVOCATION OF PROXIES

     A stockholder giving a proxy has the power to revoke it at any time before
it is exercised by (i) filing with the Clerk of Instron an instrument revoking
it, (ii) submitting a duly executed proxy bearing a later date or (iii) voting
in person at the Special Meeting. Subject to such revocation, all shares
represented by each properly executed proxy received by the Clerk of Instron
will be voted in accordance with the instructions indicated thereon, and if no
instructions are indicated, will be voted to approve the Merger Agreement and
the Transactions and in such manner as the persons named on the enclosed proxy
card in their discretion determine upon such other business as may properly come
before the Special Meeting.

     The shares of Instron Common Stock represented by the accompanying proxy
card and entitled to vote will be voted if the proxy card is properly signed and
received by the Clerk of Instron prior to the Special Meeting.

VOTING AGREEMENT

     Pursuant to the Voting Agreement, the Other Investors and certain of their
affiliates and the Management Investors and certain of their affiliates agreed
with MergerCo to vote (or cause to be voted) at the Special Meeting the Voting
Shares in favor of the proposal to approve the Merger Agreement and the
Transactions. The Other Investors and certain of their affiliates and the
Management Investors and certain of their affiliates also agreed (i) not to
sell, tender, transfer, pledge, encumber, assign or otherwise dispose of any
Voting Shares, or deposit any Voting Shares into a voting trust or enter into a
voting agreement or arrangement with respect to voting any Voting Shares or
grant any proxy or power of attorney with respect thereto, (ii) to waive their
appraisal rights with respect to the Voting Shares, and (iii) at the request of
Kirtland, to take further lawful actions as may be necessary or desirable to
consummate and make effective the transactions contemplated by the Voting
Agreement. The Voting Shares represent approximately 22.4% of the outstanding
shares of Instron Common Stock.

     The Voting Agreement will terminate upon the earlier of the consummation of
the Merger or the termination of the Merger Agreement without consummation of
the Merger.

EFFECTIVE TIME OF THE MERGER AND PAYMENT FOR SHARES

     The Effective Time of the Merger, which shall be the date and time of
filing of Articles of Merger with the Secretary of State of The Commonwealth of
Massachusetts, is currently expected to occur as soon as practicable after the
Special Meeting, subject to approval of the Merger Agreement and the
Transactions at the Special Meeting and satisfaction or waiver of the terms and
conditions of the Merger Agreement. Detailed instructions with regard to the
surrender of Instron Common Stock certificates, together with a letter of
transmittal, will be forwarded to stockholders by Instron's exchange agent,
BankBoston, N.A. (the "Exchange Agent"), promptly following the Effective Time.
Stockholders should not submit their certificates to the Exchange Agent until
they have received such materials. The Exchange Agent will send payment of the
Cash Merger Consideration to stockholders as promptly as practicable following
receipt by the Exchange Agent of their certificates and other required
documents. No interest will be paid or accrued on the cash payable upon the
surrender of certificates. Stockholders should not send any certificates at this
time.

OTHER MATTERS TO BE CONSIDERED

     The Instron Board is not aware of any other matters which will be brought
before the Special Meeting. If, however, other matters are presented, proxies
will be voted in accordance with the discretion of the holders of such proxies.

                                   THE MERGER

TERMS OF THE MERGER AGREEMENT

     General. The Merger Agreement provides that subject to satisfaction of
certain conditions, MergerCo will be merged with and into Instron, and that
following the Merger, the separate existence of MergerCo will cease and Instron
will continue as the Surviving Corporation. At the Effective Time, and subject
to the terms and conditions set forth in the Merger Agreement, each share of
issued and outstanding Instron Common Stock (other than shares of Instron Common
Stock owned by Instron or any of its wholly-owned subsidiaries, or owned by
MergerCo, or shares of Instron Common Stock as to which appraisal rights are
properly perfected and not withdrawn (collectively the "Excluded Shares")),
will, by virtue of the Merger, be canceled and converted into the right to
receive the Cash Merger Consideration. As a result of the Merger, the Instron
Common Stock will no longer be publicly traded and the equity of the Surviving
Corporation will be 100% owned by the Investor Group.


     The terms of and conditions to the Merger are contained in the Merger
Agreement which is included in full as Appendix A to this Proxy Statement and is
incorporated herein by reference. The discussion in this Proxy Statement of the
Merger and the description of the terms of the Merger Agreement constitute a
summary of the material features of the Merger and the material terms of the
Merger Agreement.


     Merger Consideration. At the Effective Time, each share of Instron Common
Stock issued and outstanding immediately prior to the Effective Time (other than
the Excluded Shares) will be converted into the right to receive the Cash Merger
Consideration. All such shares of Instron Common Stock, when converted pursuant
to the Merger Agreement, shall no longer be outstanding and shall automatically
be canceled and retired and shall cease to exist, and each certificate (a
"Certificate"), which immediately prior to the Effective Time evidenced shares
of Instron Common Stock, shall thereafter represent only the right to receive
the Cash Merger Consideration. The holders of Certificates previously evidencing
shares of Instron Common Stock outstanding immediately prior to the Effective
Time shall cease to have any rights with respect to the Instron Common Stock
except as otherwise provided in the Merger Agreement or by law and, upon the
surrender of Certificates in accordance with the Merger Agreement, shall only
represent the right to receive for their shares of Instron Common Stock, the
Cash Merger Consideration, without any interest thereon.

     At the Effective Time, each share of Series B Preferred Stock issued and
outstanding immediately prior to the Effective Time will be converted into one
share of Surviving Corporation Common Stock. All such shares of Series B
Preferred Stock, when converted pursuant to the Merger Agreement, shall no
longer be outstanding and shall automatically be canceled and retired and shall
cease to exist, and each certificate previously evidencing such shares of Series
B Preferred Stock shall thereafter represent only the right to receive shares of
Surviving Corporation Common Stock. The holders of certificates previously
evidencing shares of Series B Preferred Stock outstanding immediately prior to
the Effective Time shall cease to have any rights with respect to the Series B
Preferred Stock except as otherwise provided in the Merger Agreement or by law.
The Management Investors will in the aggregate have 33,042 shares of Series B
Preferred Stock converted in the Merger into 33,042 shares of Surviving
Corporation Common Stock. In addition, the Other Investors will in the aggregate
have 32,000 shares of Series B Preferred Stock converted in the Merger into
32,000 shares of Surviving Corporation Common Stock.

     Payment for Shares. Promptly after the Effective Time, MergerCo will cause
the Exchange Agent to mail to each holder of record of a Certificate (other than
holders of Excluded Shares) a form of letter of transmittal and instructions for
use in effecting the surrender of the Certificate in exchange for payment
therefor. Upon surrender of a Certificate for cancellation to the Exchange
Agent, together with such duly executed letter of transmittal, and any
additional requested items, the holder of such Certificate will be entitled to
receive in exchange therefor cash in an amount equal to the product of (x) the
number of shares of Instron Common Stock represented by such Certificate and (y)
the Cash Merger Consideration (net of any applicable withholding taxes).

                                       47
<PAGE>   58

     Cash-Out of Instron Stock Options. The Merger Agreement provides that each
option to purchase shares of Instron Common Stock under Instron's stock option
plans will become fully vested and exercisable, immediately prior to the Merger.
Holders of options outstanding immediately prior to the Effective Time, other
than certain options held by certain Management Investors which are to be
assumed by the Surviving Corporation and converted into the Rollover Options
(the "Cash-Out Options"), will receive cash equal to the product of (x) the
number of shares of Instron Common Stock underlying the Cash-Out Option and (y)
the excess of the Cash Merger Consideration over the per share exercise price of
such Cash-Out Option (the "Option Consideration"). Such holder will be entitled
to receive the Option Consideration from Instron upon the cancellation of such
Cash-Out Option and the surrender and cancellation of the applicable option
agreement. In connection with the Merger, holders of Cash-Out Options to
purchase an aggregate of 566,187 shares of Instron Common Stock will be entitled
to receive as Option Consideration an aggregate of approximately $5.3 million.
In addition, options to purchase up to an aggregate of 125,000 shares of Instron
Common Stock held by certain Management Investors will be assumed by the
Surviving Corporation and converted into the Rollover Options. The Rollover
Options will be governed by the 1992 Plan and the Stock Option Agreements. The
Rollover Options will be fully vested and exercisable immediately upon
consummation of the Merger.


     Payment for Restricted Stock Awards. In connection with the Merger
Agreement, all restricted stock awards granted under Instron's stock option
plans, other than restricted stock awards held by certain Management Investors
which will be converted into restricted shares of Surviving Corporation Common
Stock as described below, have vested or will vest (as of the date of approval
of the Merger Agreement by the Instron stockholders at the Special Meeting) and
the restrictions associated with such restricted stock awards have or will be
deemed automatically waived. The shares of Instron Common Stock subject to such
restricted stock awards will be treated in the Merger as Instron Common Stock
and converted into the right to receive the Cash Merger Consideration. Certain
Management Investors have agreed to waive the vesting of their restricted stock
awards with respect to an aggregate of 25,340 shares of Instron Common Stock; as
a result, these shares of restricted stock will not be cashed out as described
above, and, instead, will be assumed by the Surviving Corporation. Prior to the
Effective Time, the 25,340 shares of Instron Common Stock subject to such
restricted stock awards will be exchanged for 5,068 shares of Series B Preferred
Stock and, in the Merger, such shares of Series B Preferred Stock will be
converted into a like number of shares of restricted Surviving Corporation
Common Stock. Such shares will continue to be subject to the 1992 Plan and will
be subject to the Restricted Stock Award Agreements.


     Transfer of Shares. At the Effective Time, the stock transfer books of
Instron will be closed and there will be no further registration of transfer of
shares of Instron Common Stock thereafter on the records of Instron. If after
the Effective Time, any Certificates are presented to the Surviving Corporation
or the Exchange Agent, they will be surrendered and canceled in return for the
payment of the Cash Merger Consideration.

     Conditions to the Merger. Each party's respective obligation to effect the
Merger is subject to the fulfillment or waiver, if permissible, at or prior to
the Closing Date, of each of the following conditions: (i) the approval and
adoption of the Merger Agreement and the Transactions by the affirmative vote of
the holders of two-thirds of the outstanding shares of Instron Common Stock
entitled to vote at the Special Meeting; (ii) the waiting period (and any
extension thereof) applicable to the Merger under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, shall have expired or been
terminated; (iii) all necessary approvals, authorizations and consents of any
governmental or regulatory entity required to consummate the Merger shall have
been obtained and remain in full force and effect, and all waiting periods
relating to such approvals, authorizations and consents shall have expired or
been terminated; (iv) no preliminary or permanent injunction or other order,
decree or ruling issued by a court of competent jurisdiction or by a
governmental authority nor any statute, rule, regulation or executive order
promulgated or enacted by any governmental authority shall be in effect which
would make the consummation of the Merger illegal, or otherwise restrict,
prevent or prohibit the consummation of any of the Transactions, including the
Merger; and (v) each of the Instron Board and the Board of Directors of MergerCo
(the "MergerCo Board")

                                       48
<PAGE>   59

shall have received a letter from an appraisal firm reasonably satisfactory to
Instron indicating that immediately after the Effective Time, and after giving
effect to the Merger and the financing thereof, that the Surviving Corporation
will not be insolvent or have unreasonably small capital with which to engage in
its business.


     The obligations of MergerCo to effect the Merger are further subject to the
following conditions: (i) those representations and warranties of Instron set
forth in the Merger Agreement which are qualified by materiality or words of
similar effect shall be true and correct, and those representations and
warranties of Instron set forth in the Merger Agreement which are not so
qualified shall be true and correct in all material respects, in each case as of
the date of the Merger Agreement and as of the date of the closing date of the
Merger Agreement (the "Closing Date") as though made on and as of the Closing
Date (except to the extent such representations and warranties expressly relate
to a specific date, in which case such representations and warranties shall be
true and correct in all material respects as of such date); (ii) Instron shall
have performed in all material respects all obligations required to be performed
by it under the Merger Agreement; (iii) Instron shall have obtained or made all
third party consents, authorizations, orders or approvals identified in the
Merger Agreement or otherwise identified by MergerCo (unless not material); (iv)
there shall not have been entered any order of any governmental entity which
prohibits or limits Instron's or any of its subsidiaries' ability to own or
operate any of its business, properties or assets which is material to Instron
and its subsidiaries as a whole, or compels Instron or any of its subsidiaries
to dispose of or hold separate any portion of Instron's or its subsidiaries'
business, properties or assets which is material to Instron and its subsidiaries
as a whole; (v) there shall not have occurred any material adverse change in the
business, assets, condition (financial or otherwise) or results of operations of
Instron and its subsidiaries taken as a whole; (vi) there shall not have
occurred any material disruption or material adverse change in the banking,
financial or capital markets generally or in the market for senior credit
facilities or for new issuances of high yield securities which has caused either
of Kirtland's lenders to withdraw its respective commitment to provide financing
as contemplated by their respective financing commitment letters (a "Financing
Material Adverse Change"); (vii) as of immediately prior to the Effective Time,
no more than 5% of the outstanding shares of Instron Common Stock shall have
taken actions to assert dissenter's rights under the MBCL; (viii) the Commission
shall not have disapproved the statement in this Proxy Statement to the effect
that the Merger shall be treated as a recapitalization for accounting purposes;
(ix) there shall not be pending any action, claim, proceeding or investigation
instituted by any governmental entity challenging or prohibiting the
consummation of the Merger and the other Transactions; (x) the exchange of the
shares of Instron Common Stock of the Other Investors and the Management
Investors for Series B Preferred Stock contemplated by the Merger Agreement
shall have been completed to the reasonable satisfaction of MergerCo; and (xi)
Instron's Net Indebtedness on the Closing Date shall not exceed $13.0 million.


     The obligation of Instron to effect the Merger is further subject to the
following conditions: (i) those representations and warranties of Kirtland and
MergerCo set forth in the Merger Agreement which are qualified by materiality or
words of similar effect shall be true and correct, and those representations and
warranties of Kirtland and MergerCo set forth in the Merger Agreement which are
not so qualified shall be true and correct in all material respects, in each
case, as of the date of the Merger Agreement and as of the Closing Date as
though made on the Closing Date (except to the extent such representations and
warranties expressly relate to a specific date, in which case such
representations and warranties shall be true and correct in all material
respects as of such date); and (ii) each of Kirtland and MergerCo shall have
performed all obligations required to be performed by it under the Merger
Agreement, except where any failure to perform would, individually or in the
aggregate, not materially impair or significantly delay the ability of Instron
to consummate the Merger.

     EVEN IF THE STOCKHOLDERS APPROVE THE MERGER, THERE CAN BE NO ASSURANCE THAT
THE MERGER WILL BE CONSUMMATED.

     Representations and Warranties. Instron has made representations and
warranties in the Merger Agreement regarding, among other things, its
organization and good standing, authority to enter into the Transactions,
compliance with all applicable laws, its capitalization, its financial
statements, its ownership of

                                       49
<PAGE>   60

all subsidiaries and their organization and good standing, requisite
governmental and other consents and approvals, the content and submission of
forms and reports required to be filed by Instron with the Commission, absence
of litigation to which Instron is a party, the absence of certain changes in the
business of Instron since December 31, 1998, requisite tax filings, maintenance
of books and records, properties owned or leased by the Company, ownership or
licence for all material intellectual property, environmental matters, employee
benefits, labor matters, brokers and finders fees, opinion of financial advisor,
Year 2000 compliance, insurance, absence of defaults under material contracts,
and takeover laws.

     Certain of Instron's representations and warranties in the Merger Agreement
are qualified by the term "Company Material Adverse Effect." For purposes of the
Merger Agreement, a "Company Material Adverse Effect" means a material adverse
effect on the business, results of operations or condition (financial or
otherwise) of Instron and its subsidiaries taken as a whole.

     MergerCo and Kirtland have, jointly and severally, made representations and
warranties in the Merger Agreement regarding, among other things, their
organization and good standing, authority to enter into the Transactions, the
requisite governmental and other consents and approvals, required financing,
takeover laws, formation of MergerCo, MergerCo's beneficial ownership of shares
of Instron Common Stock, and the financial condition of Kirtland.

     Certain of the representations and warranties of MergerCo and Kirtland are
qualified by the term "Parent Material Adverse Effect." For purposes of the
Merger Agreement, a "Parent Material Adverse Effect" means a material adverse
effect on the business, results of operations or condition (financial or
otherwise) of Kirtland.

     The representations, warranties, and agreements in the Merger Agreement or
in any instrument delivered pursuant to the Merger Agreement will expire at the
Effective Time.

     Covenants. Instron has agreed under the Merger Agreement that during the
period from the date of the Merger Agreement to the Effective Time, except as
otherwise contemplated by the Merger Agreement or otherwise agreed to in writing
by MergerCo or Parent, Instron shall, and shall cause each of its subsidiaries
to, carry on their respective businesses in the usual, regular and ordinary
course, consistent with past practice, and use their best efforts to preserve
intact their present business organizations, keep available the services of
their present advisors, managers, officers and employees and preserve their
relationships with customers, suppliers, licensors and others having business
dealings with them and continue existing contracts as in effect on the date of
the Merger Agreement (for the term provided in such contracts). Specifically,
Instron has agreed not to, among other things, (i) pay dividends or make
distributions, or take certain actions with respect to its capital stock, (ii)
authorize the issuance of securities (except in connection with the
Transactions), (iii) acquire, dispose or encumber any assets outside the
ordinary course of business, (iv) make loans, advances or capital contributions
other than in the ordinary course of business, (v) pay any liabilities (other
than in the ordinary course of business or in connection with the Transactions),
(vi) take certain actions with respect to employee benefits, (vii) amend its
organizational documents (except in connection with the Transactions), or (viii)
settle or compromise any litigation.

     Instron, MergerCo and Kirtland each have also agreed to prepare and file
certain filings required under the Securities Act of 1933, as amended (the
"Securities Act"), the Exchange Act (including this Proxy Statement), or any
other federal, state or foreign law relating to the Merger and the other
Transactions.

     Financing. Under the Merger Agreement, each of Kirtland and MergerCo agreed
to use its reasonable best efforts to arrange the financing of the Transactions
and to satisfy the conditions set forth in the financing commitment letters from
Kirtland's lenders. In the event that they are unable to arrange any portion of
the financing in the manner or from the sources contemplated by such financing
commitment letters, Kirtland and MergerCo will arrange (or in the event that
such inability arises as a result of a Financing Material Adverse Change, use
its reasonable best efforts to arrange) any such portion from alternative
sources on substantially the same terms and with substantially the same
conditions as the portion of the financing that Kirtland and MergerCo were
unable to arrange. Instron will use its reasonable best efforts to assist
Kirtland and MergerCo in obtaining the financing for the Transactions.

     Solicitation of Acquisition Proposals. Under the Merger Agreement, Instron
is prohibited from authorizing or permitting any of its officers, directors or
employees or any investment banker, financial advisor, attorney, accountant or
other representative retained by it, to, directly or indirectly, (i) solicit,
initiate or encourage (including by way of furnishing non-public information),
or take any other action to facilitate, any inquiries or the making of any
proposal that constitutes a proposed or actual (A) merger, consolidation or
similar transaction involving Instron, (B) sale, lease or other disposition,
directly or indirectly, of any assets of Instron or its subsidiaries
representing 15% or more of the consolidated assets of Instron and its
subsidiaries, (C) issue, sale or other disposition by Instron of securities
representing 15% or more of the votes associated with the outstanding securities
of Instron, (D) tender offer or exchange offer in which any person or group
shall acquire beneficial ownership, or the right to acquire beneficial
ownership, of 15% or more of the outstanding shares of Instron Common Stock, or
(E) recapitalization, restructuring, liquidation, dissolution, or other similar
type of transaction with respect to Instron (an "Acquisition Proposal"), or (ii)
participate in any discussions or negotiations regarding an Acquisition
Proposal; provided, however, that at any time prior to the approval of the
Merger Agreement by the Instron stockholders, if Instron receives an Acquisition
Proposal that was unsolicited or that did not otherwise result from a breach of
the foregoing restrictions, Instron may furnish non-public information to and
participate in negotiations with the third party making the Acquisition Proposal
if (X) the Instron Board determines based on the advice of independent legal
counsel that failure to do so would be reasonably likely to constitute a breach
of its fiduciary duties to the Instron stockholders under applicable law, and
(Y) the Instron Board determines that such Acquisition Proposal is reasonably
likely to lead to an Acquisition Proposal that the Instron Board determines, on
the advice of its financial advisor, is more favorable to the Instron
stockholders from a financial point of view than the Transactions (a "Superior
Proposal"). Notwithstanding the foregoing, Instron shall, prior to furnishing
any non-public information with respect to Instron and its subsidiaries to such
third party, enter into a confidentiality agreement with such third party on
terms no less favorable than those in the confidentiality agreement executed by
Instron and Kirtland. Instron shall promptly notify (but in any event within two
calendar days) MergerCo of Instron's first receipt of a written Acquisition
Proposal by such third party and of the material terms and conditions thereof.
Instron generally shall have no duty to notify or update Kirtland or MergerCo on
the status of discussions or negotiations (including the status of such
Acquisition Proposal or any amendments or proposed amendments thereto) between
Instron and such third party.

     The Merger Agreement also provides that at any time prior to the approval
of the Merger Agreement by the Instron stockholders, the Instron Board may (i)
withdraw or modify in a manner material and adverse to Kirtland or MergerCo its
approval or recommendation of the Merger Agreement or the Merger, (ii) approve
or recommend an Acquisition Proposal to its stockholders or (iii) cause Instron
to enter into any definitive acquisition agreement with respect to an
Acquisition Proposal, in each such case if (A) the Instron Board determines
based on the advice of independent legal counsel that failure to take such
action would be reasonably likely to constitute a breach of its fiduciary duties
to the Instron stockholders under applicable law, and (B) the Instron Board
determines based on the advice of its financial advisors that such Acquisition
Proposal constitutes a Superior Proposal.

     Indemnification and Insurance. Under the Merger Agreement, Instron will
indemnify and hold harmless any person who is now, or has been at any time prior
to the date hereof, or who becomes prior to the Effective Time, a director,
officer, employee, fiduciary or agent of Instron or any of its subsidiaries, and
after the Effective Time the Surviving Corporation will indemnify and hold
harmless, as and to the full extent permitted by applicable law, each such
indemnified party against, any losses, claims, damages, liabilities, costs,
expenses (including reasonable attorneys' fees and expenses), judgments, fines
and amounts paid in settlement in connection with any threatened or actual
claim, action, suit, proceeding or investigation, whether civil, criminal or
administrative, including, without limitation, any such claim, action, suit,
proceeding or investigation in which any person who is now, or has been at any
time prior to the date of the Merger Agreement, or who becomes prior to the
Effective Time, a director, officer, employee, fiduciary or agent of Instron or
any of its subsidiaries is, or is threatened to be, made a party based in whole
or in part on, or arising in whole or in part out of, or pertaining to (i) the
fact that he is or was a director, officer, employee,

                                       51
<PAGE>   62

fiduciary or agent of Instron or any of its subsidiaries, or is or was serving
at the request of Instron or any of its subsidiaries as a director, officer,
employee, fiduciary or agent of another corporation, partnership, joint venture,
trust or other enterprise, or (ii) the negotiation, execution or performance of
the Merger Agreement or any of the Transactions (whether asserted or arising
before or after the Effective Time). The parties also agree that all rights to
indemnification existing in favor of, and all limitations on the personal
liability of, the directors, officers, employees and agents of Instron and its
subsidiaries provided for in Instron's Restated Articles of Organization or
Amended and Restated Bylaws as in effect as of the date of the Merger Agreement
with respect to matters occurring prior to the Effective Time, and including the
Merger and the Transactions, shall continue in full force and effect for a
period of six years from the Effective Time.

     Prior to the Effective Time, Instron shall purchase an extended reporting
period endorsement under its existing directors' and officers' liability
insurance coverage for Instron's directors and officers which shall provide such
directors and officers with coverage at least as favorable as the current policy
for six years following the Effective Time. If, however, the total aggregate
cost of such coverage exceeds $175,000, then Instron will instead maintain, for
such six-year period, the maximum amount of comparable coverage as shall be
available for $175,000 on such terms.

     Termination. The Merger Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval of the Merger Agreement and
the Transactions by the Instron stockholders: (a) by mutual written consent of
MergerCo and Instron; (b) by either of Instron or MergerCo (i) if the Instron
stockholders shall have failed to give the required approval of the Merger
Agreement, (ii) if any governmental authority shall have issued a permanent
injunction or taken such other final and non-appealable action which permanently
restrains, enjoins or otherwise prohibits the Merger, or (iii) if, without any
material breach by the terminating party of its obligations under the Merger
Agreement, the Merger shall not have occurred on or before November 30, 1999;
(c) by Instron (i) in connection with entering into a definitive agreement to
effect a Superior Proposal, (ii) if MergerCo or Kirtland shall have breached in
any material respect any of their respective representations, warranties,
covenants or other agreements, which breach is not cured within 15 days
following receipt by MergerCo or Kirtland of notice of such breach, except, in
any case, for such breaches which are not reasonably likely to affect Kirtland's
or MergerCo's ability to consummate the Merger, or (iii) after 60 days following
receipt by Instron of a Kirtland Financing Notice; (d) by MergerCo (i) if
Instron shall have breached in any respect any of its respective
representations, warranties or covenants, which breach is not cured within 15
days following receipt by Instron of notice of such breach, except, in any case,
for such breaches of such representations and warranties which are not
reasonably likely to result in a Company Material Adverse Effect, (ii) if the
Instron Board shall (A) fail to include a recommendation in this Proxy Statement
of the Merger Agreement and the Transactions, (B) withdraw or modify or change,
or propose or announce any intention to withdraw or modify or change, in a
manner material and adverse to MergerCo, its approval or recommendation of the
Merger Agreement or the Transactions, (C) approve or recommend or propose to
announce any intention to approve or recommend any Acquisition Proposal, or (D)
propose or announce any intention to enter into any agreement, other than a
confidentiality agreement, with respect to an Acquisition Proposal, or (iii)
after 60 days following delivery by Kirtland or MergerCo to Instron of a
Kirtland Financing Notice.


     Fees and Expenses. Generally, Instron, on the one hand, and Kirtland and
MergerCo on the other hand, will pay their own fees, costs, and expenses
incurred in connection with the Merger Agreement and the Transactions. However,
Instron will pay MergerCo "liquidated damages" in an amount equal to $5.0
million plus an amount equal to the reasonable out-of-pocket costs and expenses
incurred by Kirtland and MergerCo in connection with the Merger Agreement and
the Transactions (not to exceed $1.0 million) under certain circumstances,
including if:


     - MergerCo terminates the Merger Agreement as a result of Instron having
       wilfully breached its obligation to call a special meeting of
       stockholders or to take certain actions with respect to the preparation
       of this Proxy Statement;

     - Instron terminates the Merger Agreement in connection with entering into
       a definitive agreement to effect a Superior Proposal;
                                       52
<PAGE>   63

     - MergerCo terminates the Merger Agreement because of a material and
       adverse withdrawal, modification or change in the approval or
       recommendation of the Instron Board of the Merger Agreement or the
       Transactions; or

     - Either Instron or MergerCo terminates the Merger Agreement because the
       Instron stockholders shall have failed to approve the Merger Agreement
       and, within nine months of such termination, Instron enters into a
       definitive agreement with respect to another acquisition transaction with
       a person or an affiliate thereof who had made a proposal for an
       acquisition transaction directly to the Instron stockholders or publicly
       announced such a transaction or solicited proxies or consents in
       opposition to the Merger prior to the Special Meeting.

     Amendment. Subject to applicable law, the Merger Agreement may be amended
by the parties to the Merger Agreement; provided, however, that, after the
Merger Agreement is approved by the Instron stockholders, no such amendment
shall be made that requires further approval by the Instron stockholders without
obtaining such approval. Any amendment to the Merger Agreement must be in
writing and signed by the parties to the Merger Agreement.

ESTIMATED FEES AND EXPENSES OF THE MERGER

     Estimated fees and expenses incurred or to be incurred by the Surviving
Corporation in connection with the Transactions are approximately as follows:

                                APPRAISAL RIGHTS

     Sections 85 through 98, inclusive, of the MBCL (a copy of which is attached
hereto as Appendix C) entitle any holder of record of shares of Instron Common
Stock who files a written objection to the proposal to approve the Merger
Agreement and the Transactions, including the Merger (the "Merger Proposal"),
before the vote to approve such proposal is taken at the Special Meeting and who
does not vote in favor of the Merger Proposal to demand in writing that the
Surviving Corporation pay to such stockholder in cash the fair value of such
shares (exclusive of any element of value arising out of the expectation or
accomplishment of the Merger).

     Any person having a beneficial interest in shares of Instron Common Stock
that are held of record in the name of another person, such as a broker or
nominee, must act promptly to cause the record holder to follow the steps
summarized below properly and in a timely manner to perfect such beneficial
owner's appraisal rights, if any.

     Any stockholder of record contemplating making a demand for appraisal is
urged to review carefully the provisions of Sections 85 through 98 of the MBCL,
particularly the procedural statute specifying the requirements necessary to
perfect dissenter's appraisal rights thereunder. Appraisal rights will be lost
if the procedural requirements of Sections 85 through 98 of the MBCL are not
fully satisfied.

     SET FORTH BELOW IS A SUMMARY OF THE PROCEDURES RELATING TO THE EXERCISE OF
APPRAISAL RIGHTS. THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE A COMPLETE
STATEMENT OF THE PROVISIONS OF SECTIONS 85 THROUGH 98 OF THE MBCL AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO APPENDIX C HERETO AND TO ANY
AMENDMENTS TO SUCH SECTIONS AS MAY BE ADOPTED AFTER THE DATE OF THIS PROXY
STATEMENT.

     Filing Written Objection. An Instron stockholder who intends to exercise
appraisal rights must deliver to Instron prior to the vote of the Instron
stockholders on the Merger Proposal, a written objection to the Merger Proposal,
stating that such stockholder intends to demand payment for the shares of
Instron Common Stock held by such stockholder if the Merger is consummated. Such
written objection should be addressed to Instron Corporation, 100 Royall Street,
Canton, Massachusetts 02021, Attention: Corporate Clerk. A vote against the
Merger Proposal will not satisfy the requirement that a written objection be
filed with Instron. The written objection to the Merger Proposal must be in
addition to and separate from any proxy or vote against the Merger Proposal.

     No Vote in Favor of the Merger Proposal. Shares of Instron Common Stock for
which appraisal is sought must not be voted in favor of the Merger Proposal. The
submission of a signed blank proxy card will serve to waive appraisal rights,
but failure to return a proxy card or vote (or abstaining from vote) will not
waive appraisal rights.

     Notice By Surviving Corporation. Within ten days after the Effective Time,
the Surviving Corporation will notify each holder of record of shares of Instron
Common Stock who has purported to comply with the provisions of Section 86 of
the MBCL and whose shares were not voted in favor of the Merger Proposal that
the Merger has become effective as provided in Section 88 of the MBCL. The
giving of such notice shall not be deemed to create any rights in the
stockholder receiving the same to demand payment for such holder's shares of
Instron Common Stock. The notice shall be sent by registered or certified mail,
addressed to the stockholder at such stockholder's last known address as it
appears in the records of Instron immediately prior to the Effective Time.

     Written Demand. Within twenty days after the mailing of notice by the
Surviving Corporation, any dissenting stockholder who wishes to exercise
appraisal rights must demand in writing from the Surviving Corporation payment
for the fair value of such holder's shares of Instron Common Stock. Such written
demand should be sent to the Surviving Corporation, 100 Royall Street, Canton,
Massachusetts 02021, Attention: Corporate Clerk. The Surviving Corporation is
required to make payment of the fair value of the shares of Instron Common Stock
owned by each dissenting stockholder within thirty days (the "Payment Period")
after the expiration of the twenty day period during which a written demand for
payment may be made. If the Surviving Corporation and such stockholder shall
have agreed as to the fair value of such shares,
                                       54
<PAGE>   65

the Surviving Corporation shall pay to said stockholder the agreed value of such
stockholder's shares of Instron Common Stock within the Payment Period.

     Settlement or Appraisal. Any stockholder shall, with the Surviving
Corporation's written consent, have the right to withdraw such stockholder's
demand for appraisal and to accept the terms offered in the Merger Proposal
within four months after the expiration of the Payment Period. If the Surviving
Corporation and any stockholder seeking appraisal have not agreed on the fair
value of such holder's shares of Instron Common Stock within the Payment Period,
any such stockholder who has complied with Section 86 of the MBCL, or the
Surviving Corporation, by filing a bill in equity with the Superior Court of
Norfolk County in The Commonwealth of Massachusetts (the "Norfolk Superior
Court"), may demand a determination of the fair value of the shares of all such
stockholders. If no such bill is filed within such four-month period, no holder
of shares will be entitled to appraisal rights. Upon the filing of any such
bill, notice of the time and place fixed for a hearing will be given by the
Surviving Corporation to all stockholders who have demanded payment for their
shares and with whom agreements as to the fair value of their shares have not
been reached. After the hearing on such bill, the Norfolk Superior Court will
determine the stockholders who have complied with the provisions of Section 86
of the MBCL and who have become entitled to appraisal rights. After determining
those stockholders entitled to an appraisal, the Norfolk Superior Court shall
appraise the shares of Instron Common Stock, determining the fair value as of
the day preceding the Special Meeting and exclusive of any element of value
arising from the expectation or accomplishment of the Merger. Such determination
shall be binding on all such stockholders. Instron has not yet determined
whether it, as the Surviving Corporation, will file such a bill in equity and,
therefore, any dissenting stockholder who desires such a bill in equity to be
filed is advised to file it on a timely basis.

     Payment and Costs. When the value is so determined, the Norfolk Superior
Court will direct payment by the Surviving Corporation of such value, with
interest thereon, if any, as the Norfolk Superior Court determines, to the
stockholders entitled to receive the same upon surrender to the Surviving
Corporation by such stockholders of the Certificates representing their shares
of Instron Common Stock. The cost of the appraisal proceeding (other than
attorneys' and experts' fees) and the reasonable compensation and expenses of
any master appointed by the Norfolk Superior Court may be apportioned in such
manner as appears to the Norfolk Superior Court to be equitable; however, all
costs of giving notice to the dissenting stockholders entitled to notice of the
filing of such an action will be paid by the Surviving Corporation.


     Exclusive Remedy; Exception. The MBCL provides that the enforcement by a
stockholder of appraisal rights pursuant to the procedure summarized above is
such stockholder's exclusive remedy, except that this does not exclude the right
of such stockholder to maintain an appropriate proceeding to obtain relief on
the ground that such corporate action will be or is illegal or fraudulent as to
such stockholder. In addition, under Massachusetts law dissenting stockholders
may not be limited to the statutory remedy of judicial appraisal where
violations of fiduciary duty are found. Furthermore, dissenting stockholders may
seek remedies under the federal securities laws.


     ANY INSTRON STOCKHOLDER WHO DESIRES TO EXERCISE APPRAISAL RIGHTS SHOULD
CAREFULLY REVIEW THE MBCL AND IS ADVISED TO CONSULT SUCH STOCKHOLDER'S LEGAL
ADVISOR BEFORE EXERCISING OR ATTEMPTING TO EXERCISE SUCH RIGHTS.

                              REGULATORY APPROVALS


     Instron is required to make filings with or obtain approvals from certain
United States antitrust regulatory authorities in connection with the Merger.
These consents and approvals include the approval of the United States Federal
Trade Commission and the Department of Justice. An application and notice was
filed with the Federal Trade Commission and the Department of Justice and the
applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, expired on June 21, 1999.

     (1)  Unless otherwise indicated, Instron believes that each of the
          stockholders listed above has sole voting and investment power with
          respect to the shares of Instron Common Stock that are beneficially
          owned by them.

     (2)  Unless otherwise set forth above, the address of the listed
          stockholders is c/o Instron Corporation, 100 Royall Street, Canton,
          Massachusetts 02021.

     (3)  The number of shares beneficially owned is based solely on information
          as set forth on a Schedule 13D that reports shared voting power with
          respect to 1,560,115 shares of Instron Common Stock and shared
          dispositive power with respect to 1,560,115 shares of Instron Common

          According to the Schedule 13D, the Equity Investor, the Other
          Investors and the Management Investors may be deemed to be a group
          within the meaning of Section 13(d) of the Exchange Act as a result of
          their execution of the Voting Agreement. According to the Schedule
          13D, all securities reported are owned by the Other Investors and the
          Management Investors, but if the group exists, the group would
          beneficially own such securities. The Equity Investor disclaims
          beneficial ownership of all such securities.


     (4)  The number of shares beneficially owned is based solely on information
          as set forth on a Schedule 13G dated January 21, 1999. The Schedule
          13G provides ownership information as of December 31, 1998. David L.
          Babson & Co. has sole voting and investment power with respect to
          757,700 shares. David L. Babson & Co. is an investment counseling firm
          managing stock and bond portfolios for a variety of clients, ranging
          from large personal accounts to Fortune 500 and state government
          retirement funds.

     (5)  The number of shares beneficially owned is based solely on information
          as set forth on a Schedule 13G dated February 11, 1999. The Schedule
          13G provides ownership information as of December 31, 1998.

          registered under Section 203 of the Investment Advisors Act of 1940,
          furnishes investment advice to four investment companies registered

          manager to certain other investment vehicles, including commingled
          group trusts (collectively, the "Portfolios"). In its role as
          investment advisor and investment manager, Dimensional possesses both
          voting and investment power over the securities of Instron owned by
          the Portfolios. All securities reported are owned by the Portfolios,

     (6)  The number shown includes 91,550 shares which are owned by Mr. Burr's
          wife, as to which Mr. Burr disclaims beneficial ownership. All of
          these shares are subject to the Voting Agreement.



     (7)  Mr. Hindman has sole voting and investment power with respect to
          37,005 of these shares. The number shown also includes 492,814 shares

                        FEDERAL INCOME TAX CONSEQUENCES

     The following discussion summarizes the material federal income tax
considerations relevant to the Merger that are generally applicable to holders
of Instron Common Stock. This discussion is based on currently existing
provisions of the Code, existing and proposed Treasury Regulations thereunder,
and current administrative rulings and court decisions, all of which are subject
to change. Any such change, which may or may not be retroactive, could alter the
tax consequences to the holders of Instron Common Stock as described herein.
Special tax consequences not described below may be applicable to particular
classes of taxpayers, including financial institutions, broker-dealers, persons
who are not citizens or residents of the United States or who are foreign
corporations, foreign partnerships, or foreign estates or trusts as to the
United States, persons who will own, actually or constructively, stock of
Instron after the Merger, and holders who acquired their stock through the
exercise of an employee stock option or otherwise as compensation.

     The receipt of the Cash Merger Consideration in the Merger by holders of
Instron Common Stock will be a taxable transaction for federal income tax
purposes. Each holder's gain or loss per share of Instron Common Stock will be
equal to the difference between $22.00 and the holder's adjusted basis in that
particular share of the Instron Common Stock. Such gain or loss generally will
be a capital gain or loss. In the case of individuals, trusts, and estates, such
capital gain will be subject to a maximum federal income tax rate of 20% for
shares of Instron Common Stock held for more than 12 months prior to the date of
disposition.

     A holder of Instron Common Stock may be subject to backup withholding at
the rate of 31% with respect to Cash Merger Consideration received pursuant to
the Merger, unless the holder (a) is a corporation or comes within certain other
exempt categories and, when required, demonstrates this fact or (b) provides a
correct taxpayer identification number ("TIN"), certifies as to no loss of
exemption from backup withholding, and otherwise complies with applicable
requirements of the backup withholding rules. To prevent the possibility of
backup federal income tax withholding on payments made with respect to shares of
Instron Common Stock pursuant to the Merger, each holder must provide the
Exchange Agent with his or her correct TIN by completing a Form W-9 or
substitute Form W-9. A holder of Instron Common Stock who does not provide
Instron with his or her correct TIN may be subject to penalties imposed by the
Internal Revenue Service (the "IRS"), as well as backup withholding. Any amount
withheld under these rules will be creditable against the holder's federal
income tax liability. Instron (or its agent) will report to the holders of
Instron Common Stock and the IRS the amount of any "reportable payments," as
defined in Section 3406 of the Code, and the amount of tax, if any, withheld
with respect thereto.

     THE FOREGOING TAX DISCUSSION IS INCLUDED FOR GENERAL INFORMATION ONLY AND
IS BASED UPON PRESENT LAW. THE FOREGOING DISCUSSION DOES NOT DISCUSS TAX
CONSEQUENCES UNDER THE LAWS OF STATES OR LOCAL GOVERNMENTS OR OF ANY OTHER
JURISDICTION OR TAX CONSEQUENCES TO CATEGORIES OF STOCKHOLDERS THAT MAY BE
SUBJECT TO SPECIAL RULES, SUCH AS FOREIGN PERSONS, TAX-EXEMPT ENTITIES,
INSURANCE COMPANIES, FINANCIAL INSTITUTIONS, AND DEALERS IN STOCKS AND
SECURITIES. THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE TO A STOCKHOLDER WHO
CONTINUES TO OWN, ACTUALLY OR CONSTRUCTIVELY, STOCK OF INSTRON AFTER THE MERGER
OR WHO ACQUIRED HIS OR HER SHARES OF INSTRON COMMON STOCK PURSUANT TO THE
EXERCISE OF STOCK OPTIONS OR OTHERWISE AS COMPENSATION. EACH HOLDER OF INSTRON
COMMON STOCK SHOULD CONSULT SUCH HOLDER'S OWN TAX ADVISOR AS TO THE SPECIFIC TAX
CONSEQUENCES OF THE MERGER TO SUCH HOLDER, INCLUDING THE APPLICATION AND EFFECT
OF FEDERAL, STATE, LOCAL, AND OTHER TAX LAWS AND THE POSSIBLE EFFECT OF CHANGES
IN SUCH TAX LAWS.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA

     The following unaudited pro forma condensed consolidated financial data of
Instron has been prepared to give effect to the Merger and the other
Transactions as a leveraged recapitalization (the "Recapitalization") for
financial reporting purposes. Accordingly, the historical basis of Instron's
assets and liabilities will not be affected by the transactions. For a
discussion of the Merger and the other Transactions, see "The Merger."

     The pro forma adjustments presented are based upon available information
and certain assumptions that Instron believes are reasonable under the
circumstances. The historical condensed consolidated statement of income data
for the three months ended April 3, 1999, and the historical condensed
consolidated balance sheet data as of April 3, 1999, were derived from the
unaudited condensed consolidated financial statements of Instron included in
Instron's Quarterly Report on Form 10-Q incorporated by reference in this Proxy
Statement. The historical condensed consolidated statement of income data for
the year ended December 31, 1998 were derived from the audited consolidated
financial statements of Instron included in Instron's Annual Report on Form 10-K
incorporated by reference in this Proxy Statement.

     The unaudited pro forma condensed consolidated statement of income data of
Instron for the three months ended April 3, 1999 give effect to the Merger as if
it had occurred on January 1, 1999. The unaudited pro forma condensed
consolidated statement of income data of Instron for the year ended December 31,
1998 give effect to (i) the Merger as if it had occurred on January 1, 1998,
(ii) the acquisition of Satec on August 4, 1998 as if that acquisition had
occurred on January 1, 1998, and (iii) the acquisition of the remaining interest
in IST on September 27, 1998, as if that acquisition had occurred on January 1,
1998. The unaudited pro forma consolidated balance sheet data of Instron as of
April 3, 1999 give effect to the Merger assuming that it was completed on April
3, 1999.

     The unaudited pro forma financial data should be read in conjunction with
the historical consolidated financial statements of Instron and notes thereto,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the other financial data included elsewhere or incorporated by
reference in this Proxy Statement, as well as the information concerning the
Merger, including the sources and uses therefor, contained in "The Merger."

     The pro forma financial data and related notes are provided for
informational purposes only and do not necessarily reflect the results of
operations or financial position of Instron that would have actually resulted
had the events referred to above or in the notes to the unaudited pro forma
financial data been consummated as of the date and for the period indicated and
are not intended to project Instron's financial position or results of
operations for any future period.

    1998 to August 4, 1998 and the pre-acquisition results for the remaining
    interest in IST for the period January 1, 1998 to September 27, 1998.


(h) Pro forma basic and diluted earnings per share have been calculated giving
    effect to the new capital structure of the Surviving Corporation. Pro Forma
    weighted average number of basic common shares includes shares of
    Recapitalized Common Stock outstanding, assuming the Recapitalization was
    consummated at the beginning of the period presented. Pro Forma weighted
    average number of diluted common shares includes shares of Recapitalized
    Common Stock outstanding plus the effect of any dilutive potential common
    shares that were outstanding during the period, assuming the
    Recapitalization was consummated at the beginning of the period presented.
    Potential common shares include rollover options held by management.


(i) Because interest rates in connection with the Credit Facility and the debt
    securities have not been determined as of the date hereof, the pro forma
    data is indicative of Instron's best current estimate of interest expense. A
    1/8 percentage point increase or decrease in the assumed interest rates on
    the Credit Facility and the debt securities would change the annual net
    interest expense by approximately $35 and $140 for the three months ended
    April 3, 1999, and the year ended December 31, 1998, respectively.

(j) The Unaudited Pro Forma Condensed Consolidated Statements of Income have not
    been adjusted to reflect the following non-recurring costs (benefits):

(A) Due to Instron's Pro Forma loss in the three month period ended April 3,
    1999, the ratio coverage was less than 1:1. Instron would have had to
    generate additional earnings of $658,000 to achieve a coverage ratio of 1:1
    for the period.

if so desired.

                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The following documents previously filed with the Commission by Instron
(SEC File No. 001-05641) are incorporated by reference in this Proxy Statement:

     All documents filed by Instron with the Commission pursuant to Sections

to the date of the Special Meeting shall be deemed to be incorporated by
reference herein and shall be a part hereof from the date of filing of such
documents. Any statements contained in a document incorporated by reference
herein or contained in this Proxy Statement shall be deemed to be modified or
superseded for purposes hereof to the extent that a statement contained herein
(or in any other subsequently filed document which also is incorporated by
reference herein) modifies or supersedes such statement. Any statement so
modified or superseded shall not be deemed to constitute a part hereof except as
so modified or superseded.


                             STOCKHOLDER PROPOSALS


     If the Merger is not consummated for any reason, stockholder proposals
intended to be presented at Instron's 2000 Annual Meeting of Stockholders must
be received by Instron on or before December 16, 1999 in order to be considered
for inclusion in Instron's proxy statement and form of proxy for that meeting.
These proposals must also comply with the rules of the Commission governing the
form and content of proposals in order to be included in Instron's proxy
statement and form of proxy and should be directed to: Clerk, Instron
Corporation, 100 Royall Street, Canton, Massachusetts, 02021.

     If the Merger is not consummated for any reason, a stockholder who wishes
to present a proposal at Instron's 2000 Annual Meeting of Stockholders, other
than a proposal to be considered for inclusion in Instron's proxy statement and
form of proxy as described above, must deliver the proposal to Instron at the
address set forth above. Such written proposal must be delivered not less than
75 days nor more than 120 days prior to the date of the scheduled annual
meeting; provided, however, that in the event that less than 90 days notice or
prior public disclosure of the scheduled date of the meeting is given or made to
stockholders, such written proposal must be received no later than the close of
business on the 15th day following the day on which such notice of the scheduled
date of the meeting was mailed or such disclosure was made, whichever first
occurs. The proposal must also comply with the other requirements contained in
Instron's Amended and Restated By-laws, including supporting documentation and
other information. Proxies solicited by the Instron Board will confer
discretionary voting authority with respect to these proposals, subject to the
Commission's rules governing the exercise of this authority.

                                 OTHER MATTERS


     Management knows of no other business to be presented at the Special
Meeting. If other matters do properly come before the meeting, or any
adjournment or postponement thereof, it is the intention of the persons named in
the proxy to vote on such matters according to their best judgment and in their
discretion.

     WHEREAS, as a condition to the willingness of Parent and MergerCo to enter
into this Agreement, certain stockholders of the Company (the "Voting Agreement
Stockholders") have entered into a Voting Agreement, dated as of the date
hereof, with Parent and MergerCo (the "Voting Agreement"), pursuant to which
each Voting Agreement Stockholder has agreed, among other things, to vote his
shares of Common Stock in favor of the approval of the Transactions and the
approval of any other matter relating to consummation of the Transactions, upon
the terms and subject to the conditions set forth in the Voting Agreement;

     WHEREAS, Parent, MergerCo and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Transactions, and also to prescribe various conditions to the Transactions; and

     WHEREAS, it is intended that the Merger be recorded as a recapitalization
for financial reporting purposes.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, Parent, MergerCo and the Company hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1 The Merger. Subject to the terms and conditions of this Agreement, at
the Effective Time, the Company and MergerCo shall consummate the Merger
pursuant to which (a) MergerCo shall be merged with and into the Company and the
separate corporate existence of MergerCo shall thereupon cease, (b) the Company
shall be the successor or surviving corporation in the Merger (sometimes
hereinafter referred to as the "Surviving Corporation") and shall continue to be
governed by the laws of the Commonwealth of Massachusetts, and (c) the separate
corporate existence of the Company with all its rights, privileges, immunities,
powers and franchises shall continue unaffected by the Merger. The Company shall
take such steps as are permitted under the MBCL to (i) amend the Articles of
Organization of the Company (the "Articles of Organization") so that the
Articles of Organization of MergerCo, as in effect immediately prior

                                       A-1
<PAGE>   88

to the Effective Time, shall be the Articles of Organization of the Surviving
Corporation until thereafter amended as provided by law and such Articles of
Organization, and (ii) amend the Bylaws of the Company (the "Bylaws") so that
the Bylaws of MergerCo, as in effect immediately prior to the Effective Time,
shall be the Bylaws of the Surviving Corporation until thereafter amended as
provided by law, by the Articles of Organization of the Surviving Corporation
and by such Bylaws. Notwithstanding the foregoing, the name of the Surviving
Corporation shall be "Instron Corporation" and the Articles of Organization and
Bylaws of the Surviving Corporation shall so provide. The Merger shall have the
effects specified in the MBCL. The purpose of the Surviving Corporation shall be
to carry on a manufacturing, contracting, merchandising, and research business,
and in general, to carry on any business or other activity which may be lawfully
carried on by a corporation organized under Chapter 156B of the Massachusetts
General Laws (the "MGL").

     1.2 Effective Time. On the Closing Date (as hereinafter defined), MergerCo
and the Company shall duly execute and file articles of merger (the "Articles of
Merger") with the Secretary of State of the Commonwealth of Massachusetts in
accordance with the MBCL. The Merger shall become effective at such time as the
Articles of Merger, accompanied by payment of the filing fee (as provided in
Chapter 156B, Section 114 of the MBCL), have been examined by and received the
endorsed approval of the Secretary of State of the Commonwealth of Massachusetts
(the "Effective Time").

     1.3 Closing. The closing of the Merger (the "Closing") shall occur as
promptly as practicable (but in no event later than the second business day)
after all of the conditions set forth in Article VIII shall have been satisfied
or, if permissible, waived by the party entitled to the benefit of the same,
and, subject to the foregoing, shall take place at such time and on a date to be
specified by the parties (the "Closing Date"); provided, however, that in no
event shall the Closing occur earlier than July 8, 1999. The Closing shall take
place at the offices of Jones, Day, Reavis & Pogue, 901 Lakeside Avenue,
Cleveland, Ohio 44114, unless another place is agreed to by the parties hereto.

     1.4 Directors and Officers. The directors of MergerCo immediately prior to
the Effective Time shall be the initial directors of the Surviving Corporation
and the officers of the Company immediately prior to the Effective Time shall be
the initial officers of the Surviving Corporation, each to hold office in
accordance with the Articles of Organization and Bylaws of the Surviving
Corporation.

                                   ARTICLE II

                   EFFECT OF THE MERGER ON THE CAPITAL STOCK
                        OF THE CONSTITUENT CORPORATIONS

     2.1 Effect on Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of Common
Stock or Series B Stock (as hereinafter defined) or any shares of capital stock
of MergerCo:

          (a) Each share of common stock, par value $.01 per share, of MergerCo
     (the "MergerCo Common Stock") issued and outstanding immediately prior to
     the Effective Time shall be converted into one fully paid and nonassessable
     share of common stock, par value $1.00 per share, of the Surviving
     Corporation (the "Surviving Corporation Common Stock") following the
     Merger.

          (b) Each share of Common Stock that is owned by the Company, or by any
     wholly owned Subsidiary (as defined in Section 10.2) of the Company or by
     MergerCo shall automatically be canceled and retired and shall cease to
     exist, and no cash or other consideration shall be delivered or deliverable
     in exchange therefor.

          (c) Each share of Common Stock issued and outstanding immediately
     prior to the Effective Time (other than shares owned by the Company, any of
     its wholly owned Subsidiaries or MergerCo and Dissenting Shares (as defined
     in Section 3.2)) shall be converted into the right to receive $22.00 per
     share, net to the seller in cash, payable to the holder thereof, without
     any interest thereon (the "Merger Consideration"), upon surrender and
     exchange of the Certificate (as hereinafter defined) representing such
     share of Common Stock.

                                       A-2
<PAGE>   89

          (d) Each share of Series B Preferred Stock, par value $1.00 per share,
     of the Company (the "Series B Stock") issued and outstanding immediately
     prior to the Effective Time (other than shares owned by the Company or any
     of its wholly owned Subsidiaries) shall be converted into one fully paid
     and nonassessable share of Surviving Corporation Common Stock following the
     Merger.

          (e) All shares of Common Stock, when converted as provided in Section
     2.1(c), shall no longer be outstanding and shall automatically be canceled
     and retired and shall cease to exist, and each Certificate (as hereinafter
     defined) previously evidencing such shares shall thereafter represent only
     the right to receive the Merger Consideration. The holders of Certificates
     previously evidencing shares of Common Stock outstanding immediately prior
     to the Effective Time shall cease to have any rights with respect to the
     Common Stock except as otherwise provided herein or by law and, upon the
     surrender of Certificates in accordance with the provisions of Section 3.1,
     shall only represent the right to receive for their shares of Common Stock,
     the Merger Consideration, without any interest thereon.

          (f) All shares of Series B Stock, when converted as provided in
     Section 2.1(d) shall no longer be outstanding and shall automatically be
     canceled and retired and shall cease to exist, and each certificate
     previously evidencing such shares of Series B Stock shall thereafter
     represent only the right to receive shares of Surviving Corporation Common
     Stock. The holders of certificates previously evidencing shares of Series B
     Stock outstanding immediately prior to the Effective Time shall cease to
     have any rights with respect to the Series B Stock except as otherwise
     provided herein or by law.

     2.2 Company Stock Options and Related Matters.

     (a) Each option (collectively, the "Options") granted under the Company's
1992 Stock Incentive Plan (the "1992 Plan"), the 1984 United Kingdom Share
Option Scheme (the "1984 Plan"), the 1982 Incentive Stock Option Plan (the "1982
Plan") and the 1979 Non-Qualified Plan (the "1979 Plan" and, together with the
1992 Plan, the 1984 Plan and the 1982 Plan, the "Stock Option Plans"), which is
outstanding (whether or not then exercisable) as of immediately prior to the
Effective Time and which has not been exercised or canceled prior thereto (other
than the Options identified in Section 2.2 of the Company Disclosure Schedule
(as hereinafter defined), such Options being hereinafter referred to as the
"Rollover Options"), shall, at the Effective Time, be canceled and upon the
surrender and cancellation of the option agreement representing such Option, the
Company shall (x) pay to the holder thereof cash in an amount equal to the
product of (i) the number of shares of Common Stock provided for in such Option
and (ii) the excess, if any, of the Merger Consideration over the exercise price
per share provided for in such Option, which cash payment shall be treated as
compensation and shall be net of any applicable federal or state withholding tax
(the "Option Consideration"). The Company shall take all actions necessary to
ensure that (i) all Options, to the extent not exercised prior to the Effective
Time, shall terminate and be canceled as of the Effective Time and thereafter be
of no further force or effect, and (ii) no Options are granted after the date of
this Agreement.

     (b) Each Rollover Option which is outstanding (whether or not then
exercisable) as of immediately prior to the Effective Time shall, at the
Effective Time, be automatically converted into an option to acquire 0.2 fully
paid and nonassessable shares of Surviving Corporation Common Stock at an
exercise price per share equal to (i) five (5) multiplied by (ii) the exercise
price per share provided for in the Option for which such Rollover Option is
surrendered; provided, however, that such exercise price shall be rounded up to
the nearest whole cent. From and after the Effective Time, the Rollover Options
shall be governed by the terms of the Stock Option Plans applicable to the
Option for which such Rollover Option is surrendered. The adjustments provided
herein with respect to any Rollover Options that are "incentive stock options"
as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), shall be and are intended to be effected in a manner which is
consistent with Section 424(a) of the Code.

     (c) Except as set forth in Section 2.2 of the Company Disclosure Schedule,
the Stock Option Plans shall terminate as of the Effective Time and the
provisions in any other plan, program or arrangement providing for the issuance
or grant of any other interest in respect of the capital stock of the Company or
any of the Company Subsidiaries shall be of no further force and effect and
shall be deemed to be deleted as of the Effective Time and no holder of an
Option or any participant in any Stock Option Plan or any other plans,

                                       A-3
<PAGE>   90

programs or arrangements (other than holders of Rollover Options) shall have any
right thereunder to acquire any equity securities of the Company, the Surviving
Corporation or any Subsidiary thereof.

     (d) Except as set forth in Section 2.2 of the Company Disclosure Schedule,
Parent and MergerCo acknowledge that all restricted stock awards granted under
the Stock Option Plans shall immediately vest and the restrictions associated
therewith shall automatically be deemed waived as provided by the Stock Option
Plans but in no event later than the date on which the Company's stockholders
approve this Agreement and the Transactions.

                                  ARTICLE III

                     PAYMENT FOR SHARES; DISSENTING SHARES

     3.1 Payment for Shares of Company Common Stock.

     (a) From and after the Effective Time, such bank or trust company as shall
be mutually acceptable to MergerCo and the Company shall act as exchange agent
(the "Exchange Agent"). At or prior to the Effective Time, MergerCo shall
deposit, or MergerCo shall otherwise take all steps necessary to cause to be
deposited, with the Exchange Agent in an account (the "Exchange Fund") the
aggregate Merger Consideration (net of any applicable withholding taxes) to
which holders of shares of Common Stock shall be entitled at the Effective Time
pursuant to Section 2.1(c).

     (b) Promptly after the Effective Time, MergerCo shall cause the Exchange
Agent to mail to each record holder of Certificates (the "Certificates") that
immediately prior to the Effective Time represented shares of Common Stock a
form of letter of transmittal which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
proper delivery of the Certificates to the Exchange Agent and instructions for
use in surrendering such Certificates and receiving the Merger Consideration in
respect thereof.

     (c) In effecting the payment of the Merger Consideration with respect to
shares of Common Stock represented by Certificates entitled to payment of the
Merger Consideration pursuant to Section 2.1(c) (the "Cashed Shares"), upon the
surrender of each such Certificate, the Exchange Agent shall pay the holder of
such Certificate the Merger Consideration multiplied by the number of Cashed
Shares (net of any applicable withholding taxes), in consideration therefor.
Upon such payment such Certificate shall forthwith be canceled.

     (d) Until surrendered in accordance with paragraph (c) above, each such
Certificate (other than Certificates representing shares of Common Stock held by
MergerCo or any of its affiliates, in the treasury of the Company or by any
wholly owned Subsidiary of the Company or Dissenting Shares) shall represent
solely the right to receive the Merger Consideration relating thereto. No
interest or dividends shall be paid or accrued on the Merger Consideration. If
the Merger Consideration (or any portion thereof) is to be delivered to any
person other than the person in whose name the Certificate formerly representing
shares of Common Stock surrendered therefor is registered, it shall be a
condition to such right to receive such Merger Consideration that the
Certificate so surrendered shall be properly endorsed or otherwise be in proper
form for transfer and that the person surrendering such shares of Common Stock
shall pay to the Exchange Agent any transfer or other taxes required by reason
of the payment of the Merger Consideration to a person other than the registered
holder of the Certificate surrendered, or shall establish to the satisfaction of
the Exchange Agent that such tax has been paid or is not applicable.

     (e) No dividends or other distributions with respect to shares of Common
Stock shall be paid to the holder of any unsurrendered Certificate with respect
to the shares of Common Stock represented thereby.

     (f) Promptly following the date which is 180 days after the Effective Time,
the Exchange Agent shall deliver to the Surviving Corporation all cash,
Certificates and other documents in its possession relating to the Transactions,
and the Exchange Agent's duties shall terminate. Thereafter, each holder of a
Certificate formerly representing a share of Common Stock may surrender such
Certificate to the Surviving Corporation and (subject to applicable abandoned
property, escheat and similar laws) receive in consideration therefor the Merger
Consideration relating thereto without any interest or dividends thereon.
                                       A-4
<PAGE>   91

     (g) After the Effective Time, there shall be no transfers on the stock
transfer books of the Surviving Corporation of any shares of Common Stock which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates formerly representing shares of Common Stock are
presented to the Surviving Corporation or the Exchange Agent, they shall be
surrendered and canceled in return for the payment of the Merger Consideration
relating thereto, as provided in this Article III.

     (h) None of Parent, MergerCo, the Company or the Exchange Agent shall be
liable to any person in respect of any cash from the Exchange Fund delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law. If any Certificate shall not have been surrendered prior to seven
years after the Effective Time, any such shares, cash, dividends or
distributions in respect of such Certificate shall, to the extent permitted by
applicable law, become the property of the Surviving Corporation, free and clear
of all claims or interest of any person previously entitled thereto.

     3.2 Appraisal Rights.

     (a) Notwithstanding anything in this Agreement to the contrary, any shares
of Common Stock ("Dissenting Shares") which are issued and outstanding
immediately prior to the Effective Time and which are held by stockholders of
the Company who have filed with the Company, before the taking of the vote of
the stockholders of the Company to approve this Agreement, written objections to
such approval stating their intention to demand payment for such shares of
Common Stock, and who have not voted such shares of Common Stock in favor of the
adoption of this Agreement, will not be converted as described in Section 2.1
hereof, but will thereafter constitute only the right to receive payment of the
fair value of such shares of Common Stock in accordance with the applicable
provisions of Chapter 156B of the MBCL (the "Appraisal Rights Provisions");
provided, however, that all shares of Common Stock held by stockholders who
shall have failed to perfect or who effectively shall have withdrawn or lost
their rights to appraisal of such shares of Common Stock under the Appraisal
Rights Provisions shall thereupon be deemed to have been canceled and retired
and to have been converted, as of the Effective Time, into the right to receive
the Merger Consideration, without interest, in the manner provided in Section
2.1. Persons who have perfected statutory rights with respect to Dissenting
Shares as aforesaid will not be paid by the Surviving Corporation as provided in
this Agreement and will have only such rights as are provided by the Appraisal
Rights Provisions with respect to such Dissenting Shares. Notwithstanding
anything in this Agreement to the contrary, if Parent, MergerCo or the Company
abandon or are finally enjoined or prevented from carrying out, or the
stockholders rescind their adoption of, this Agreement, the right of each holder
of Dissenting Shares to receive the fair value of such Dissenting Shares in
accordance with the Appraisal Rights Provisions will terminate, effective as of
the time of such abandonment, injunction, prevention or rescission. The Company
shall give MergerCo prompt notice of any demands received by the Company for the
exercise of appraisal rights with respect to shares of Common Stock and Parent
shall have the right to participate in all negotiations and proceedings with
respect to such demands. The Company shall not, except with the prior written
consent of Parent (which shall not be unreasonably withheld), make any payment
with respect to, or settle or offer to settle, any such demands.

     (b) Each dissenting stockholder who becomes entitled under the MBCL to
payment for Dissenting Shares shall receive payment therefor after the Effective
Time from the Surviving Corporation (but only after the amount thereof shall
have been agreed upon or finally determined pursuant to the MBCL), and such
shares of Common Stock shall be canceled.

                                   ARTICLE IV

                       REPRESENTATIONS AND WARRANTIES OF
                              PARENT AND MERGERCO

     Parent and MergerCo jointly and severally hereby represent and warrant to
the Company as follows:

     4.1 Organization. Parent is a limited partnership duly organized and
validly existing under the laws of the State of Ohio and MergerCo is a
corporation duly organized, validly existing and in good standing under the laws
of the Commonwealth of Massachusetts, and each has all requisite power and
authority and all
                                       A-5
<PAGE>   92

necessary governmental approvals to own, lease and operate their properties and
to carry on their businesses as now being conducted, except where the failure to
be so organized, existing and in good standing or to have such power, authority,
and governmental approvals would not have a material adverse effect on the
business, results of operations or condition (financial or otherwise) of Parent
(a "Parent Material Adverse Effect"). Parent is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the property owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification or licensing necessary, except where the failure to be so
duly qualified or licensed and in good standing would not, individually or in
the aggregate, have a Parent Material Adverse Effect.

     4.2 Authorization; Validity of Agreement; Necessary Action. Each of Parent
and MergerCo has full power and authority to execute and deliver this Agreement
and to consummate the Transactions. The execution, delivery and performance by
Parent and MergerCo of this Agreement and the consummation of the Transactions
have been duly authorized by all necessary partnership action on behalf of
Parent (the "Parent Board") and the Board of Directors of MergerCo (the
"MergerCo Board") and by the stockholders of MergerCo, and, except as set forth
in Section 4.2 of the schedule attached to this Agreement setting forth
exceptions to Parent's and MergerCo's representations and warranties set forth
herein (the "Parent and MergerCo Disclosure Schedule"), no other action on the
part of Parent and MergerCo is necessary to authorize the execution and delivery
by Parent and MergerCo of this Agreement and the consummation of the
Transactions. This Agreement has been duly executed and delivered by Parent and
MergerCo and, assuming due and valid authorization, execution and delivery
hereof by the Company, is a valid and binding obligation of each of Parent and
MergerCo, as the case may be, enforceable against each of them in accordance
with its terms, subject to applicable bankruptcy, insolvency, moratorium or
other similar laws relating to creditors' rights and general principles of
equity.

     4.3 Consents and Approvals; No Violations. Except as set forth in Section
4.2 of the Parent and MergerCo Disclosure Schedule and except for filings,
permits, authorizations, consents and approvals as may be required under, and
other applicable requirements of, the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), the Securities Act of 1933, as amended (the
"Securities Act"), the HSR Act (as hereinafter defined), the antitrust and
competition laws of foreign countries and state securities or state "Blue Sky"
laws, none of the execution, delivery or performance of this Agreement by Parent
or MergerCo, the consummation by Parent or MergerCo of the Transactions or
compliance by Parent or MergerCo with any of the provisions hereof will (i)
conflict with or result in any breach of any provision of the limited
partnership agreement of Parent or the articles of organization or bylaws of
MergerCo, (ii) require any filing with, or permit, authorization, consent or
approval of, any Governmental Entity (as hereinafter defined), (iii) result in a
violation or breach of, or constitute (with or without due notice or lapse of
time or both) a default (or give rise to any right of termination, cancellation
or acceleration) under, any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, lease, license, contract, agreement or other
instrument or obligation to which Parent or MergerCo is a party or by which
either of them or any of their respective properties or assets may be bound, or
(iv) violate any order, writ, injunction, decree, statute, rule or regulation
applicable to Parent or MergerCo or any of their properties or assets, excluding
from the foregoing clauses (ii), (iii) and (iv) such violations, breaches or
defaults which would not, individually or in the aggregate, have a Parent
Material Adverse Effect.

     4.4 Required Financing. Parent and MergerCo have revolving credit facility
and high yield bridge financing commitments in place which, if funded in
accordance with their terms, together with equity capital commitments from the
limited partners of Parent and certain additional equity capital commitments
from certain of the limited partners of Parent (the "Side-by-Side Equity
Commitments"), will provide sufficient funds to consummate the Transactions
(collectively, the "Transaction Costs"), including, without limitation, to (i)
pay the Merger Consideration pursuant to Section 2.1(c), (ii) refinance the
outstanding indebtedness of the Company, (iii) pay any fees and expenses in
connection with the Transactions or the financing thereof and (iv) provide for
the working capital needs of the Company following the Merger, including,
without limitation, if applicable, letters of credit. Neither Parent nor
MergerCo has any reason to believe that any condition to such financing
commitments cannot or will not be waived or satisfied prior to the Effective
Time. Parent has provided to the Company true, complete and correct copies of
all financing commitment letters

                                       A-6
<PAGE>   93

executed by the revolving credit facility lender and the high yield bridge
lender (collectively, the "Lenders"), including any exhibits, schedules or
amendments thereto (the "Financing Letters"). Parent has provided to the Company
true, complete and correct copies of each Side-by-Side Equity Commitment letter
executed by the limited partner of Parent signatory thereto, including any
exhibits, schedules or amendments thereto. The advisory board of Parent has
approved an investment by Parent of $40,000,000 of Fund Capital (as hereinafter
defined) in the Company and, from and after the date of this Agreement, the
advisory board of Parent shall not withdraw or change such approval unless this
Agreement shall have been terminated in accordance with its terms.

     4.5 Takeover Laws. Neither Parent nor MergerCo was, immediately prior to
the execution of this Agreement, an "interested stockholder" within the meaning
of Chapter 110F of the MGL.

     4.6 Formation of MergerCo; No Prior Activities. MergerCo was formed solely
for the purpose of engaging in the transactions contemplated by this Agreement.
As of the date hereof and as of the Effective Time, except for (i) obligations
or liabilities incurred in connection with its incorporation or organization and
the transactions contemplated by this Agreement and (ii) this Agreement and any
other agreements or arrangements contemplated by this Agreement or in
furtherance of the transactions contemplated hereby, MergerCo has not incurred,
directly or indirectly, through any subsidiary or affiliate, any obligations or
liabilities or engaged in any business activities of any type or kind whatsoever
or entered into any agreements or arrangements with any person.

     4.7 Beneficial Ownership. Except to the extent permitted by Section 7.16
hereof or as a result of the execution by Parent and MergerCo of the Voting
Agreement, neither Parent nor MergerCo "beneficially owns" (as defined in Rule
13d-3 under the Exchange Act) any shares of Common Stock or any securities
convertible into or exchangeable for Common Stock.

     4.8 Financial Condition of Parent. Parent has provided to the Company true,
complete and correct copies of the audited financial statements of Parent for
the fiscal year ended December 31, 1998 and the unaudited financial statements
of Parent for the interim period ended March 31, 1999. Such financial statements
fairly present the financial position of Parent as of the respective dates
thereof, and the other related statements (including the related notes) included
therein fairly present the results of operations of Parent for the respective
fiscal periods set forth above. Parent has equity commitments from its limited
partners in an aggregate amount in excess of $185,000,000 (the "Fund Capital").
The General Partner may, in its sole discretion, call such portion of the Fund
Capital as is necessary to satisfy any of Parent's or MergerCo's obligations
under or arising out of this Agreement and the performance by Parent and
MergerCo thereof. None of the Fund Capital has been pledged or is subject to any
material lien, security interest or other encumbrance.

                                   ARTICLE V
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as set forth in the disclosure schedules delivered at or prior to
the execution hereof to Parent and MergerCo, which shall refer to the relevant
Sections of this Agreement (the "Company Disclosure Schedule"), the Company
represents and warrants to Parent and MergerCo as follows:

     5.1 Existence; Good Standing; Authority; Compliance With Law.

     (a) The Company is a corporation duly organized, validly existing and in
good standing under the laws of the Commonwealth of Massachusetts and has all
requisite corporate or other power and authority and all necessary governmental
approvals to own, lease and operate its properties and to carry on its business
as now being conducted, except where the failure to be so organized, existing
and in good standing or to have such power, authority and governmental approvals
would not reasonably be expected to have a Company Material Adverse Effect (as
hereinafter defined). Except as set forth in Section 5.1 of the Company
Disclosure Schedule, the Company is duly qualified or licensed to do business
and is in good standing (with respect to jurisdictions that recognize such
concept) in each jurisdiction in which the nature of its business or the

                                       A-7
<PAGE>   94

ownership, leasing or operation of its properties makes such qualification or
licensing necessary, except for those jurisdictions where the failure to be so
qualified or licensed or to be in good standing, individually or in the
aggregate, would not reasonably be expected to have a Company Material Adverse
Effect. For purposes of this Agreement, a "Company Material Adverse Effect"
shall mean a material adverse effect on the business, results of operations or
condition (financial or otherwise) of the Company and the Company Subsidiaries
taken as a whole.

     (b) Except as set forth in Section 5.1 of the Company Disclosure Schedule,
each of the Company Subsidiaries is a corporation, partnership or limited
liability company (or similar entity or association in the case of those Company
Subsidiaries organized and existing other than under the laws of a State of the
United States) duly incorporated or organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation or organization,
has the corporate or other power and authority to own its properties and to
carry on its business as it is now being conducted, and is duly qualified to do
business and is in good standing in each jurisdiction in which the ownership of
its property or the conduct of its business requires such qualification, except
for jurisdictions in which such failure to be so qualified or to be in good
standing could not reasonably be expected to have a Company Material Adverse
Effect.

     (c) Neither the Company nor any of the Company Subsidiaries is in violation
of any order of any court, governmental authority or arbitration board or
tribunal, or any law, ordinance, governmental rule or regulation to which the
Company or any Company Subsidiary or any of their respective properties or
assets is subject, where such violation could have a Company Material Adverse
Effect. The Company and the Company Subsidiaries have obtained all licenses,
permits and other authorizations and have taken all actions required by
applicable law or governmental regulations in connection with their businesses
as now conducted, where the failure to obtain any such license, permit or
authorization or to take any such action could have a Company Material Adverse
Effect.

Schedule, copies of the Articles of Organization and Bylaws and the other
charter documents, bylaws, organizational documents and partnership, limited
liability company and joint venture agreements (and in each such case, all

respects.

     5.2 Authorization, Validity and Effect of Agreements. Each of the Company

foregoing, the Company Board has taken such actions and votes as are necessary
on its part to render the provisions of Chapter 110C and Chapter 110F of the MGL
and all other applicable takeover statutes inapplicable to this Agreement and
the Transactions. Subject only to the approval of this Agreement by the holders
of the Common Stock, the execution by the Company of this Agreement and
consummation of the Transactions have been duly authorized by all requisite
corporate action on the part of the Company. This Agreement, assuming due and
valid authorization, execution and delivery thereof by Parent and MergerCo,
constitutes a valid and legally binding obligation of the Company, enforceable
against the Company in accordance with its terms, subject to applicable
bankruptcy, insolvency, moratorium or other similar laws relating to creditors'
rights and general principles of equity.

of the date of this Agreement, the Company had no shares of Common Stock
reserved for issuance other than as described above. Section 5.3 of the Company
Disclosure Schedule sets forth a description of the Common Stock, the Preferred

Agreement and other than awards made pursuant to any of the Stock Option Plans,
there are no agreements or understandings to which the Company or any Company
Subsidiary is a party with respect to the voting of any shares of capital stock
of the Company or which restrict the transfer of any such shares, nor does the
Company have knowledge of any third party agreements or understandings with
respect to the voting of any such shares or which restrict the transfer of any
such shares. Other than (i) as set forth above, (ii) awards made pursuant to any

securities).

     5.6 No Violation; Consents. Except as set forth in Section 5.6 of the

accordance with the terms hereof, will conflict with or result in a breach of
any provisions of the Articles of Organization, Bylaws, or the organizational
documents of the Company or any Company Subsidiary. Except as set forth in
Section 5.6 of the Company Disclosure Schedule, the execution and delivery by
the Company of this Agreement and consummation by the Company of the
Transactions in accordance with the terms hereof will not violate, or conflict
with, or result in a breach of any provision of, or constitute a default (or an
event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination or in a right of termination or cancellation
of, or accelerate the performance required by, or result in the creation of any
lien, security interest, charge or encumbrance upon any of the properties of the
Company or the Company Subsidiaries under, or result in being declared void,
voidable or without further binding effect, any of the terms, conditions or
provisions of (x) any note, bond, mortgage, indenture, deed of trust or (y) any
license, franchise, permit, lease, contract, agreement or other instrument,
commitment or obligation to which the Company or any of the Company Subsidiaries
is a party, or by which the Company or any of the Company Subsidiaries or any of
their properties is bound, except as otherwise would not have a Company Material
Adverse Effect. Other than the filings provided for in Article II of this
Agreement, the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR
Act"), the antitrust and competition laws of foreign countries, the Exchange
Act, the Securities Act, or applicable state securities and "Blue Sky" laws
(collectively, the "Regulatory Filings"), the execution and delivery of this
Agreement by the Company does not, and the performance of this Agreement by the
Company and consummation of the Transactions does not, require any consent,
approval or authorization of, or declaration, filing or registration with, any
governmental or regulatory authority, except where the failure to obtain any
such consent, approval or authorization of, or declaration, filing or
registration with, any governmental or regulatory authority would not have a
Company Material Adverse Effect.

     5.7 SEC Documents. The Company has filed all required forms, reports and
documents with the Securities and Exchange Commission (the "SEC") since December
31, 1995 (collectively, the "Company SEC Reports"), all of which were prepared
in accordance with the applicable requirements of the Exchange Act, the
Securities Act and the rules and regulations promulgated thereunder (the
"Securities Laws"). All required Company SEC Reports have been filed with the
SEC and constitute all forms, reports and documents required to be filed by the
Company under the Securities Laws since December 31, 1995. As of their
respective dates, the Company SEC Reports (i) complied as to form in all
material respects with the applicable requirements of the Securities Laws and
(ii) did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading. Each of the consolidated balance sheets of the Company included in
or incorporated by reference into the Company SEC Reports (including the related
notes and schedules) fairly presents the consolidated financial position of the
Company and the Company Subsidiaries as of its date and each of the consolidated
statements of income, retained earnings and cash flows of the Company included

material in amount or effect), in each case in accordance with generally
accepted accounting principles consistently applied during the periods involved,
except as may be noted therein and except, in the case of the unaudited
statements, as permitted by Form 10-Q pursuant to Section 13 or 15(d) of the
Exchange Act.

properties, is pending, or, to the knowledge of the Company, threatened, other

business operations conducted by the Company and the Company Subsidiaries and
which have arisen or been incurred only in the ordinary course of business.

<PAGE>   99

and the Company Subsidiaries as currently conducted, taken as a whole,
including, without limitation, trade names, unregistered trademarks and service
marks, brand names, software, patents and copyrights, except where the failure
to own or be a licensee for such intangible property would not have a Company
Material Adverse Effect. Except as disclosed in Section 5.13 of the Company
Disclosure Schedule, there are no claims pending or, to the Company's knowledge,
threatened, that the Company or any Company Subsidiary is in violation of any
such intellectual property right of any third party which would have a Company

in violation of any intellectual property rights of the Company or any Company
Subsidiary which would have a Company Material Adverse Effect.

     5.14 Environmental Matters. The Company and the Company Subsidiaries are in
compliance with all Environmental Laws (as hereinafter defined), except for any
noncompliance that, either singly or in the aggregate, would not reasonably be
expected to have a Company Material Adverse Effect. As used in this Agreement,
"Environmental Laws" shall mean all federal, state, local and foreign laws,

thereof. There is no administrative or judicial enforcement or cost recovery
proceeding pending, or to the best knowledge of the Company threatened, against
the Company or any Company Subsidiary under any Environmental Law. Neither the
Company nor any Company Subsidiary or, to the best knowledge of the Company, any
legal predecessor of the Company or any Company Subsidiary, has received any
written notice that it is potentially responsible under any Environmental Law
for any costs of response or for damages to natural resources, as those terms
are defined under the Environmental Laws, at any location and neither the
Company nor any Company Subsidiary has transported or disposed of, or allowed or
arranged for any third party to transport or dispose of, any waste containing
Hazardous Materials at any location included on the National Priorities List, as
defined under the Comprehensive Environmental Response, Compensation, and
Liability Act, or any location proposed for inclusion on that list or at any
location on any analogous state list. Except for any release that, either
individually or in the aggregate, would not reasonably be expected to have a
Company Material Adverse Effect, there has been no release on the real property
owned or leased by the Company or any Company Subsidiary, or, to the Company's
knowledge, on the real property owned or leased by any predecessor entity, which
real property currently is owned or leased by the Company or any Company
Subsidiary, of Hazardous Materials, or, with respect to any real property
located outside of the United States, any hazardous or toxic material or
substance regulated under any foreign Environmental Law, in a manner that could
result in an order to perform a response action or in material liability under
the Environmental Laws and, except as set forth in Section 5.14 of the Company
Disclosure Schedule, there is no hazardous waste treatment, storage or disposal
facility, underground storage tank, landfill, surface impoundment, underground
injection well, or, to the Company's knowledge, friable asbestos or PCB's, as
those terms are defined under the Environmental Laws, located at any of the real
property owned or leased by the Company or any Company Subsidiary or, to the
Company's knowledge, any predecessor entity, or at any facilities utilized by
the Company or the Company Subsidiaries. The Company has disclosed and made
available to MergerCo all studies, analyses and test results in the possession,
custody or control of the Company or any Company Subsidiary relating to the
environmental conditions on or under any of the properties or assets owned,
leased or operated by the Company or any Company Subsidiary. Except as set forth
in Section 5.14 of the Company Disclosure Schedule, the Company and the Company
Subsidiaries hold all permits, licenses or authorizations required under

     5.15 Employee Benefit Plans.

     (a) Section 5.15 of the Company Disclosure Schedule sets forth a list of
every Company Benefit Plan (as hereinafter defined) that is maintained by the
Company or an Affiliate (as hereinafter defined) on the date hereof.

     (b) Each Company Benefit Plan which has been intended to qualify under
Section 401(a) of the Code has received a favorable determination or approval
letter from the Internal Revenue Service (the "IRS") regarding its qualification
under such section and neither the Company nor any Affiliate knows that any such
Company Benefit Plan has been maintained in a manner that would preclude
qualified status.

     (c) Except as set forth in Section 5.15 of the Company Disclosure Schedule,
neither the Company nor any Affiliate knows of any failure of any party to
comply with any laws applicable with respect to the Company Benefit Plans. With
respect to any Company Benefit Plan, there has been no (i) "prohibited
transaction," as defined in Section 406 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), or Code Section 4975, for which an
exemption is not available or (ii) material failure to comply with any provision
of ERISA, other applicable law, or any agreement, which, in either case, would
subject the Company or any Affiliate to liability (including, without
limitation, through any obligation of indemnification or contribution) for any
damages, penalties, or taxes, or any other material loss or expense. No
litigation or governmental administrative proceeding (or investigation) or other
proceeding (other than those relating to routine claims for benefits) is pending
or, to the Company's knowledge, threatened with respect to any such Company
Benefit Plan.

     (d) Neither the Company nor any Affiliate has incurred any liability under
title IV of ERISA which has not been paid in full as of the date of this
Agreement. There has been no "accumulated funding deficiency" (whether or not
waived) with respect to any employee pension benefit plan ever maintained by the
Company or any Affiliate and subject to Code Section 412 or ERISA Section 302.
With respect to any Company Benefit Plan maintained by the Company or any
Affiliate and subject to Title IV of ERISA, there has been no (nor will there be
any as a result of the Transactions) (i) "reportable event," within the meaning
of ERISA Section 4043 or the regulations thereunder, for which the notice
requirement is not waived by the regulations thereunder, and (ii) event or
condition which presents a material risk of a plan termination or any other
event that may cause the Company or any Affiliate to incur liability or have a
lien imposed on its assets under Title IV of ERISA. Neither the Company nor any
Affiliate has ever maintained a Multiemployer Plan (as hereinafter defined).

     (e) With respect to each Company Benefit Plan, complete and correct copies
of the following documents (if applicable to such Company Benefit Plan) have
previously been delivered to MergerCo or its representatives: (i) all documents
embodying or governing such Company Benefit Plan, and any funding medium for
such Company Benefit Plan (including, without limitation, trust agreements) as
they may have been amended to the date hereof; (ii) the most recent IRS
determination or approval letter with respect to such Company Benefit Plan under
Code Section 401(a), and any applications for determination or approval
subsequently filed with the IRS; (iii) the three most recently filed IRS Forms
5500, with all applicable schedules and accountants' opinions attached thereto;
(iv) the current summary plan description for such Company Benefit Plan (or
other descriptions of such Company Benefit Plan provided to employees) and all
modifications thereto; and (v) any insurance policy (including any fiduciary
liability insurance policy or fidelity bond) related to such Company Benefit
Plan.

     (f) With respect to each group health plan benefitting any current or
former employee of the Company or any Affiliate that is subject to Section 4980B
of the Code, or was subject to Section 162(k) of the Code, the Company and each
Affiliate have complied in all material respects with (i) the continuation
coverage requirements of Section 4980B of the Code and Section 162(k) of the
Code, as applicable, and Part 6 of Subtitle B of Title I of ERISA and (ii) the
Health Insurance Portability and Accountability Act of 1996, as amended.

     (g) With respect to any insurance policy providing funding for benefits
under any Company Benefit Plan, (i) there is no liability of the Company or any
Affiliate in the nature of a retroactive rate adjustment,

                                      A-14
<PAGE>   101

loss sharing arrangement, or other actual or contingent liability, nor would
there be any such liability if such insurance policy was terminated on the date
hereof, and (ii) to the knowledge of the Company, no insurance company issuing
any such policy is in receivership, conservatorship, liquidation or similar
proceeding and no such proceedings with respect to any insurer are imminent.

     (h) Except as set forth in Section 5.15 of the Company Disclosure Schedule,
no Company Benefit Plan provides benefits, including, without limitation, death
or medical benefits, beyond termination of service or retirement other than (i)
coverage mandated by law, (ii) death or retirement benefits under any qualified
Company Benefit Plan, or (iii) deferred compensation benefits reflected on the
books of the Company or an Affiliate.

     (i) Except as set forth in Section 5.15 of the Company Disclosure Schedule,
the execution and performance of this Agreement will not (i) constitute a stated
triggering event under any Company Benefit Plan that will result in any payment
(whether of severance pay or otherwise) becoming due from the Company or any
Affiliate to any officer, employee, or former employee (or dependents of such
employee), or (ii) accelerate the time of payment or vesting, or increase the
amount of compensation due to any employee, officer or director of the Company
or any Affiliate.

     (j) Except as set forth in Section 5.15 of the Company Disclosure Schedule,
(i) any amount that could be received (whether in cash or property or the
vesting of property) as a result of any of the transactions contemplated by this
Agreement by any employee, officer or director of the Company or any Affiliate
who is a "disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or Company Benefit Plan currently in
effect would not be characterized as an "excess parachute payment" (as such term
is defined in Section 280G(b)(1) of the Code), and (ii) the disallowance of a
deduction under Section 162(m) of the Code for employee remuneration will not
apply to any amount paid or payable by the Company or any Affiliate under any
contract, Company Benefit Plan, program, arrangement or understanding currently
in effect.

     (k) For purposes of this Section:

          (i) "Company Benefit Plan" means (A) all employee benefit plans within
     the meaning of ERISA Section 3(3) maintained by the Company or any
     Affiliate, including, but not limited to, multiple employer welfare
     arrangements (within the meaning of ERISA Section 3(40)), plans to which
     more than one unaffiliated employer contributes and employee benefit plans
     (such as foreign or excess benefit plans) which are not subject to ERISA;
     (B) all stock option plans, stock purchase plans, bonus or incentive award
     plans, severance pay policies or agreements, deferred compensation
     agreements, supplemental income arrangements, vacation plans, and all other
     employee benefit plans, agreements, and arrangements not described in (A)
     above maintained by the Company or any Affiliate, including without
     limitation, any arrangement intended to comply with Code Section 120, 125,
     127, 129 or 137; and (C) all plans or arrangements providing compensation
     to employee and non-employee directors maintained by the Company or any
     Affiliate. In the case of a Company Benefit Plan funded through a trust
     described in Code Section 401(a), or any other funding vehicle, each
     reference to such Company Benefit Plan shall include a reference to such
     trust, organization or other vehicle;

          (ii) An entity "maintains" a Company Benefit Plan if such entity
     sponsors, contributes to, or provides benefits under or through such
     Company Benefit Plan, or has any obligation (by agreement or under
     applicable law) to contribute to or provide benefits under or through such
     Company Benefit Plan, or if such Company Benefit Plan provides benefits to
     or otherwise covers employees of such entity (or their spouses, dependents,
     or beneficiaries);

          (iii) An entity is an "Affiliate" of the Company for purposes of this
     Section 5.15 if it would have ever been considered a single employer with
     the Company under ERISA Section 4001(b) or part of the same "controlled
     group" as the Company for purposes of ERISA Section 302(d)(8)(C); and

                                      A-15
<PAGE>   102

          (iv) "Multiemployer Plan" means an employee pension or welfare benefit
     plan to which more than one unaffiliated employer contributes and which is
     maintained pursuant to one or more collective bargaining agreements.

     5.16 Labor Matters. Except as set forth in Section 5.16 of the Company
Disclosure Schedule, neither the Company nor any Company Subsidiary is a party
to, or bound by, any collective bargaining agreement, contract or other
agreement or understanding with a labor union or labor union organization. There
is no unfair labor practice or labor arbitration proceeding pending or, to the
knowledge of the Company, threatened against the Company or any of the Company
Subsidiaries relating to their business, except for any such proceeding which
would not reasonably be expected to have a Company Material Adverse Effect. To
the Company's knowledge there are no organizational efforts with respect to the
formation of a collective bargaining unit presently being made or threatened
involving employees of the Company or any of the Company Subsidiaries.

     5.17 No Brokers. Neither the Company nor any of the Company Subsidiaries
has entered into any contract, arrangement or understanding with any person or
firm which may result in the obligation of such entity or MergerCo to pay any
finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or consummation of
the Transactions, except that the Company has retained The Beacon Group Capital
Services, L.L.C. ("Beacon Group") as its financial advisor in connection with
the Transactions, a true copy of any and all agreements between the Company and
Beacon Group, including the engagement letter entered into between the Company
and Beacon Group, have been delivered to MergerCo. Other than the foregoing
arrangements, the Company is not aware of any claim for payment of any finder's
fees, brokerage or agent's commissions or other like payments in connection with
the negotiations leading to this Agreement or consummation of the Transactions.

     5.18 Opinion of Financial Advisors. The Company has received the opinion of
Beacon Group to the effect that, as of the date hereof, the Merger Consideration
is fair to the holders of the Common Stock from a financial point of view.

     5.19 Year 2000. There is no impediment to the Company being year 2000
compliant by December 31, 1999 (i.e., that products, hardware, software and
other date-sensitive equipment manufactured, sold, owned, licensed or used by
the Company will be capable of correctly processing date data (including, but
not limited to, calculating, comparing and sequencing) accurately prior to,
during and after the calendar year 2000 when used, assuming that all third party
products, hardware, software and other date-sensitive equipment used in
combination therewith are capable of properly exchanging date data), except to
the extent that any such impediment would not have a Company Material Adverse
Effect.

     5.20 Insurance. The Company and the Company Subsidiaries are covered by
insurance in scope and amount customary and reasonable for the businesses in
which they are engaged. Except as disclosed in Section 5.20 of the Disclosure
Schedule, each insurance policy to which the Company or any of the Company
Subsidiaries is a party is in full force and effect and will not require any
consent as a result of the consummation of the Transactions. Neither the Company
nor any of the Company Subsidiaries is in material breach or default (including
with respect to the payment of premiums or the giving of notices) under any
insurance policy to which it is a party, and no event has occurred which, with
notice or the lapse of time, would constitute such a material breach or default
by the Company or any of the Company Subsidiaries or would permit termination,
modification or acceleration, under such policies; and the Company has not
received any notice from the insurer disclaiming coverage or reserving rights
with respect to any material claim or any such policy in general.

     5.21 Contracts. Neither the Company nor any of the Company Subsidiaries is
in breach, nor has the Company or any Company Subsidiary received in writing any
claim that it has breached, any of the terms or conditions of any material
agreement, contract or commitment (excluding leases) to which it is a party or
by which any of its assets and properties are bound (collectively, "Material
Contracts") in such a manner as would permit any other party to cancel or
terminate the same prior to its stated term or would permit any other party to
collect material damages from the Company under any such Material Contract.
Neither the Company nor any of the Company Subsidiaries is in breach, nor has
the Company or any Company
                                      A-16
<PAGE>   103

Subsidiary received in writing any claim that it has breached, any of the terms
or conditions of any lease to which it is a party and which is material to the
business of the Company and the Company Subsidiaries taken as a whole
(collectively, "Material Leases"), in such a manner as would permit any other
party to cancel or terminate the same prior to its stated term or would permit
any other party to collect material damages from the Company under any such
Material Lease. Each Material Contract and Material Lease is in full force and
effect and to the Company's knowledge is not subject to any material default
thereunder by any party obligated to the Company or any of the Company
Subsidiaries thereunder. The Company is not a party to any "poison pill,"
shareholder rights plan, rights agreement or similar agreement, instrument, plan
or arrangement.

     5.22 Takeover Laws. No "fair price," "moratorium," "control share
acquisition" or other similar anti-takeover statute or regulation enacted under
state or federal laws in the United States including, without limitation,
Chapter 110F of the MGL, applicable to the Company or any of the Company
Subsidiaries is applicable to the execution, delivery and performance of this
Agreement or the consummation of the Merger or the other Transactions.

     5.23 Vote Required. The affirmative vote of the holders of two-thirds of
the outstanding shares of Common Stock entitled to vote thereon is the only vote
of any class of capital stock of the Company required by the MBCL, the Articles
of Organization or the Bylaws to adopt this Agreement and approve the
Transactions.

     5.24 Definition of the Company's Knowledge. As used in this Agreement, the
phrase "to the knowledge of the Company" or any similar phrase means the actual
(and not the constructive or imputed) knowledge (following a reasonable inquiry)
of those individuals identified in Section 5.24 of the Company Disclosure
Schedule.

                                   ARTICLE VI
                     CONDUCT OF BUSINESS PENDING THE MERGER

     under any such confidentiality, "standstill" or similar agreement if the

     7.1 Stockholders Meeting.

     (a) The Company, acting through the Company Board, shall, in accordance

     action upon this Agreement and the Transactions (it being understood that
     the date of the Special Meeting shall be reasonably acceptable to Parent);

          (ii) as promptly as practicable (but in no event later than

under the HSR Act), the Company, Parent and MergerCo each shall properly prepare
and file any other filings required under the Exchange Act or any other federal,
state or foreign law relating to the Merger and the Transactions (including
filings, if any, required under the HSR Act) (collectively, the "Other
Filings"). Each of the Company, MergerCo and Parent shall promptly notify the
other of the receipt of any comments on, or any request for amendments or
supplements to, any of the Other Filings by the SEC or any other Governmental
Entity or official, and each of the Company, Parent and MergerCo shall supply
the other with copies of all correspondence between it and each of its
Subsidiaries and representatives, on the one hand, and the SEC or the members of
its staff or any other appropriate governmental official, on the other hand,
with respect to any of the Other Filings. The Company, Parent and MergerCo each

Governmental Entity for the Transactions, including without limitation, promptly
entering into a consent decree or other arrangement with the FTC or other
Governmental Entity as may be necessary to secure termination of such waiting
periods or obtain such other approval. Parent and MergerCo shall make any
undertakings (including undertakings to make divestitures) required in order to
comply with the antitrust requirements or laws of any Governmental Entity,
including the HSR Act, in connection with the Transactions.

     7.3 Additional Agreements. Subject to the terms and conditions herein
provided, each of the parties hereto agrees to use its reasonable best efforts
to take, or cause to be taken, all actions and to do, or cause to be done, all
things necessary, proper or advisable to consummate and make effective as
promptly as practicable the Transactions and to cooperate with each other in
connection with the foregoing, including the taking of such actions as are
necessary to obtain any necessary consents, approvals, orders, exemptions and
authorizations by or from any public or private third party, including without
limitation any that are required to be obtained under any federal, state or
local law or regulation or any contract, agreement or instrument to which the
Company or any Company Subsidiary is a party or by which any of their respective
properties or assets are bound, to defend all lawsuits or other legal
proceedings challenging this Agreement or the consummation of the Transactions,
to cause to be lifted or rescinded any injunction or restraining order or other
order adversely affecting the ability of the parties to consummate the
Transactions, and to effect all necessary registrations and Other Filings,
including, but not limited to, filings under the HSR Act, if any, and
submissions of information requested by governmental authorities. For purposes
of the foregoing sentence, the obligation of the Company, Parent and MergerCo to
use their "reasonable best efforts" to obtain waivers, consents and approvals to
loan agreements, leases and other contracts shall not include any obligation to

                                      A-20
<PAGE>   107

agree to an adverse modification of the terms of such documents or to prepay or
incur additional obligations to such other parties.

     7.4 Fees and Expenses. Except as set forth in Section 9.2 hereof, whether
or not the Merger is consummated, all fees, costs and expenses incurred in
connection with this Agreement and the Transactions shall be paid by the party
incurring such costs or expenses.

     7.5 No Solicitations.

     (a) The Company represents and warrants that it has terminated any
discussions or negotiations relating to, or that may be reasonably be expected
to lead to, any Acquisition Proposal (as hereinafter defined) and will promptly
request the return of all confidential information regarding the Company
provided to any third party prior to the date of this Agreement pursuant to the
terms of any confidentiality agreements. Except as permitted by this Agreement,
the Company shall not, and shall not authorize or permit any of its officers,
directors or employees or any investment banker, financial advisor, attorney,
accountant or other representative retained by it to, directly or indirectly,
(i) solicit, initiate or encourage (including by way of furnishing non-public
information), or take any other action to facilitate, any inquiries or the
making of any proposal that constitutes an Acquisition Proposal, or (ii)
participate in any discussions or negotiations regarding an Acquisition
Proposal; provided, however, that, at any time prior to the approval of this
Agreement by the stockholders of the Company, if the Company receives an
Acquisition Proposal that was unsolicited or that did not otherwise result from
a breach of this Section 7.5(a), the Company may furnish non-public information
with respect to the Company and the Company Subsidiaries to the person who made
such Acquisition Proposal (a "Third Party") and may participate in negotiations
regarding such Acquisition Proposal if (A) the Company Board determines based on
the advice of independent legal counsel that failure to do so would be
reasonably likely to constitute a breach of its fiduciary duties to the
Company's stockholders under applicable law, and (B) the Company Board
determines that such Acquisition Proposal is reasonably likely to lead to a
Superior Proposal (as hereinafter defined). Notwithstanding the foregoing, the
Company shall, prior to furnishing non-public information with respect to the
Company and the Company Subsidiaries to such Third Party, enter into a
confidentiality agreement with such Third Party with terms no less favorable to
the Company than those contained in the Confidentiality Agreement, provided that
such confidentiality agreement need not include the same standstill provisions
as those contained in the Confidentiality Agreement, it being understood that if
there are no standstill provisions in such confidentiality agreement or if such
provisions are more favorable to such Third Party than those in the
Confidentiality Agreement, the Confidentiality Agreement shall be deemed amended
to exclude the existing standstill provision or include such more favorable
provisions, as the case may be. The Company shall promptly notify (but in any
event within two (2) calendar days) MergerCo of the Company's first receipt of a
written Acquisition Proposal by such Third Party and of the material terms and
conditions thereof. Notwithstanding anything to the contrary in this Agreement,
the Company shall not be required to disclose to Parent or MergerCo the identity
of the Third Party making any such Acquisition Proposal and, except as provided
in Section 9.1(c)(i), shall have no duty to notify or update Parent or MergerCo
on the status of discussions or negotiations (including the status of such
Acquisition Proposal or any amendments or proposed amendments thereto) between
the Company and such Third Party.

     (b) Subject to Section 9.1(d)(ii) hereof, at any time prior to the approval
of this Agreement by the stockholders of the Company, the Company Board may (i)
withdraw or modify in a manner material and adverse to Parent or MergerCo its
approval or recommendation of this Agreement or the Merger, (ii) approve or
recommend an Acquisition Proposal to its stockholders or (iii) cause the Company
to enter into any definitive acquisition agreement with respect to an
Acquisition Proposal, in each such case if (A) the Company Board determines
based on the advice of independent legal counsel that failure to take such
action would be reasonably likely to constitute a breach of its fiduciary duties
to the Company's stockholders under applicable law, and (B) the Company Board
determines based on the advice of its financial advisors that such Acquisition
Proposal constitutes a Superior Proposal. Any such withdrawal, modification or
change of the recommendation of the Company Board of this Agreement shall not
change the approval of the Company Board of this Agreement for purposes of
causing any state takeover statute or other state law to be inapplicable to the
Transactions, including the Merger.

     (c) Nothing contained in this Section 7.5 shall prohibit the Company from
at any time taking and disclosing to its stockholders a position contemplated by
Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or making any
disclosure required by Rule 14a-9 promulgated under the Exchange Act.

     (d) As used in this Agreement, the term "Acquisition Proposal" shall mean
any proposed or actual (i) merger, consolidation or similar transaction
involving the Company, (ii) sale, lease or other disposition, directly or
indirectly, by merger, consolidation, share exchange or otherwise, of any assets
of the Company or the Company Subsidiaries representing 15% or more of the
consolidated assets of the Company and the Company Subsidiaries, (iii) issue,
sale or other disposition by the Company of (including by way of merger,

options, rights or warrants to purchase, or securities convertible into, such
securities) representing 15% or more of the votes associated with the
outstanding securities of the Company, (iv) tender offer or exchange offer in
which any person shall acquire beneficial ownership (as such term is defined in
Rule 13d-3 under the Exchange Act), or the right to acquire beneficial

the Transactions.

     (e) As used in this Agreement, the term "Superior Proposal" means an
Acquisition Proposal that the Company Board determines based on the advice of
its financial advisors is more favorable to the stockholders of the Company from
a financial point of view than the Transactions (taking into account all of the
terms and conditions of such Acquisition Proposal, including any conditions to
consummation and the likelihood of such Acquisition Proposal being consummated).

     7.6 Officers' and Directors' Indemnification.

     (a) In the event of any threatened or actual claim, action, suit,
proceeding or investigation, whether civil, criminal or administrative,
including, without limitation, any such claim, action, suit, proceeding or
investigation in which any person who is now, or has been at any time prior to
the date hereof, or who becomes prior to the Effective Time, a director,
officer, employee, fiduciary or agent of the Company or any of the Company
Subsidiaries (the "Indemnified Parties") is, or is threatened to be, made a
party based in whole or in part on, or arising in whole or in part out of, or
pertaining to (i) the fact that he is or was a director, officer, employee,
fiduciary or agent of the Company or any of the Company Subsidiaries, or is or
was serving at the request of the Company or any of the Company Subsidiaries as
a director, officer, employee, fiduciary or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (ii) the negotiation,
execution or performance of this Agreement or any of the Transactions, whether
in any case asserted or arising before or after the Effective Time, the parties
hereto agree to cooperate and use their reasonable best efforts to defend
against and respond thereto. It is understood and agreed that the Company shall
indemnify and hold harmless, and after the Effective Time the Surviving
Corporation shall indemnify and hold harmless, as and to the full extent
permitted by applicable law, each Indemnified Party against any losses, claims,
damages, liabilities, costs, expenses (including reasonable attorneys' fees and
expenses), judgments, fines and amounts paid in settlement in connection with
any such threatened or actual claim, action, suit, proceeding or investigation,
and in the event of any such threatened or actual claim, action, suit,
proceeding or investigation (whether asserted or arising before or after the
Effective Time), (A) the Company, and the Surviving Corporation after the
Effective Time, shall promptly pay expenses in advance of the final disposition
of any claim, suit, proceeding or investigation to each Indemnified Party to the
full extent permitted by law, (B) the Indemnified Parties may retain counsel
satisfactory to them, and the Company and the Surviving Corporation, shall pay
all fees and expenses of such counsel for the Indemnified Parties within thirty
days after statements therefor are received, and (C) the Company and the
Surviving Corporation will use their respective reasonable best efforts to
assist in the vigorous defense of any such matter; provided, however, that
neither the Company nor the Surviving Corporation shall be liable for any
settlement effected without its prior written consent (which consent shall not
be unreasonably withheld); and provided further, however, that the Surviving
Corporation shall have no obligation hereunder to any Indemnified Party when
                                      A-22
<PAGE>   109

and if a court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and non-appealable, that indemnification
of such Indemnified Party in the manner contemplated hereby is prohibited by
applicable law. Any Indemnified Party wishing to claim indemnification under
this Section 7.6, upon learning of any such claim, action, suit, proceeding or
investigation, shall notify the Company and, after the Effective Time, the
Surviving Corporation, thereof, provided that the failure to so notify shall not
affect the obligations of the Company and the Surviving Corporation except to
the extent such failure to notify materially prejudices such party.

(b) Parent and MergerCo agree that all rights to indemnification existing in
favor of, and all limitations on the personal liability of, the directors,
officers, employees and agents of the Company and the Company Subsidiaries
provided for in the Articles of Organization or Bylaws as in effect as of the
date hereof with respect to matters occurring prior to the Effective Time, and
including the Merger and the Transactions, shall continue in full force and
effect for a period of six (6) years from the Effective Time; provided, however,
that all rights to indemnification in respect of any claims (each a "Claim")
asserted or made within such period shall continue until the disposition of such
Claim. Prior to the Effective Time, the Company shall purchase an extended
reporting period endorsement ("Reporting Tail Coverage") under the Company's
existing directors' and officers' liability insurance coverage for the Company's
directors and officers in a form acceptable to the Company which shall provide
such directors and officers with coverage for six (6) years following the
Effective Time of not less than the existing coverage under, and have other
terms not materially less favorable to, the insured persons than the directors'
and officers' liability insurance coverage presently maintained by the Company;
provided, however, than in any event the total aggregate cost of such Reporting
Tail Coverage shall not exceed $175,000 (the "Maximum Amount"); and provided,
further, that if such coverage cannot be obtained for such cost, the Company
will maintain, for such six-year period, the maximum amount of comparable
coverage as shall be available for the Maximum Amount on such terms.

     (c) This Section 7.6 is intended for the irrevocable benefit of, and to
grant third party rights to, the Indemnified Parties and shall be binding on all
successors and assigns of Parent, MergerCo, the Company and the Surviving
Corporation. Each of the Indemnified Parties shall be entitled to enforce the
covenants contained in this Section 7.6.

     (d) In the event that the Surviving Corporation or any of its successors or
assigns (i) consolidates with or merges into any other person or entity and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers or conveys all or substantially all of
its properties and assets to any person or entity, then, and in each such case,
proper provision shall be made so that the successors and assigns of the
Surviving Corporation assume the obligations set forth in this Section 7.6.

     7.7 Access to Information; Confidentiality. From the date hereof until the
Effective Time, the Company shall, and shall cause each of the Company
Subsidiaries and each of the Company's and Company Subsidiaries' officers,
employees, customers, suppliers, lenders and agents to, afford to MergerCo and
to the officers, employees and agents of MergerCo complete access at all
reasonable times to such officers, employees, agents, properties, books, records
and contracts, and shall furnish MergerCo such financial, operating and other
data and information as MergerCo may reasonably request. Prior to the Effective
Time, Parent and MergerCo shall hold in confidence all such information on the
terms and subject to the conditions contained in that certain confidentiality
agreement between Parent and the Company dated October 30, 1998 (the
"Confidentiality Agreement"). The Company hereby waives the provisions of the
Confidentiality Agreement as and to the extent necessary to permit the making
and consummation of the Transactions. At the Effective Time, such
Confidentiality Agreement shall terminate. Each party shall give prompt written
notice to the other of any fact, event or circumstance known to it that would be
reasonably likely to cause or constitute a material breach of any of its
representations or warranties contained herein or a Company Material Adverse
Effect or Parent Material Adverse Effect, as applicable.

     7.8 Financial and Other Statements. Notwithstanding anything contained in
Section 7.7, during the term of this Agreement, the Company shall also provide
to MergerCo or its representatives the following documents and information:

          (a) As soon as reasonably available after filing with the SEC, the
     Company will deliver to MergerCo or its representatives the Company's
     Quarterly Report on Form 10-Q as filed under the Exchange Act for each
     fiscal quarter ending after the date of this Agreement. As soon as
     reasonably available after filing with the SEC, the Company will deliver to
     MergerCo or its representatives the Company's Annual Report on Form 10-K,
     as filed under the Exchange Act for each fiscal year ending after the date
     of this Agreement. The Company will also deliver to MergerCo or its
     representatives, contemporaneously with its being filed with the SEC, a
     copy of each Current Report on Form 8-K. As soon as reasonably available,
     the Company will deliver to MergerCo or its representatives copies of
     financial reports for each calendar month ending after the date of this
     Agreement prepared by the Company's management in the ordinary course of
     business.

          (b) Promptly upon receipt thereof, the Company will furnish to
     MergerCo or its representatives copies of all internal control reports
     submitted to the Company or any Company Subsidiary by independent
     accountants in connection with each annual, interim or special audit of the
     books of the Company or any such Company Subsidiary made by such
     accountants.

          (c) As soon as practicable, the Company will furnish to MergerCo or
     its representatives copies of all such financial statements and reports as
     the Company or any Company Subsidiary shall send to its stockholders, the
     SEC or any other regulatory authority, to the extent any such reports
     furnished to any such regulatory authority are not confidential and except
     as legally prohibited thereby.

     7.9 Public Announcements. The Company and MergerCo shall consult with each
other before issuing any press release or otherwise making any public statements
with respect to this Agreement or any of the Transactions and shall not issue
any such press release or make any such public statement without the prior
consent of the other party, which consent shall not be unreasonably withheld;
provided, however, that a party may, without the prior consent of the other
party, issue such press release or make such public statement as may be required
by law or the applicable rules of any stock exchange if it has used its best
efforts to consult with the other party and to obtain such party's consent but
has been unable to do so in a timely manner. In this regard, the parties shall
make a joint public announcement of the Transactions contemplated thereby no
later than (i) the close of trading on the American Stock Exchange on the day
this Agreement is signed, if such signing occurs during a business day or (ii)
the opening of trading on the American Stock Exchange on the business day
following the date on which this Agreement is signed, if such signing does not
occur during a business day.

     7.10 Employee Benefit Arrangements. Section 7.10 of the Company Disclosure
Schedule sets forth each employment or severance agreement to which the Company
or any Company Subsidiary is presently a party. MergerCo agrees that the Company
will honor, and from and after the Effective Time, the Surviving Corporation
will honor, all obligations under such employment and severance agreements.

     7.11 Required Financing. Each of Parent and MergerCo hereby agrees to use
its reasonable best efforts to arrange the financing in respect of the
Transactions and to satisfy the conditions set forth in the Financing Letters.
Parent and MergerCo shall keep the Company informed of the status of their
financing arrangements for the Transactions, including providing written
notification to the Company as promptly as possible (but in any event within
forty-eight (48) hours) with respect to (i) any indication that either of the
Lenders may be unable to provide the financing as contemplated by the Financing
Letters, including without limitation, any indication from either of the Lenders
that there has occurred a material disruption or material adverse change in the
banking, financial or capital markets generally or in the market for senior
credit facilities or for new issuances of high yield securities which has caused
or could cause such Lender to withdraw its commitment to provide financing as
contemplated by the Financing Letters, (ii) the ability of Parent or MergerCo to
satisfy any of the conditions set forth in the Financing Letters, and (iii) any
adverse developments relating to the financing contemplated by the Financing
Letters. Parent shall provide written notice to the Company within twenty-four
(24) hours if either of the Lenders has indicated to Parent or MergerCo that
such Lender
                                      A-24
<PAGE>   111

will be unable to provide the financing contemplated by the applicable Financing
Letter (a "Parent Financing Notice"). In the event Parent and MergerCo are
unable to arrange any portion of such financing in the manner or from the
sources contemplated by the Financing Letters, Parent and MergerCo shall arrange
(or, in the event that such inability to arrange financing arises under the
circumstances contemplated by Section 8.2(f) hereof, use its reasonable best
efforts to arrange) any such portion from alternative sources on substantially
the same terms and with substantially the same conditions as the portion of the
financing that Parent and MergerCo were unable to arrange. The Company shall use
its reasonable best efforts to assist Parent and MergerCo in obtaining their
financing; provided, however, that the obligation of the Company to use its
reasonable best efforts in connection with the foregoing shall only apply to
reasonable and customary activities in this regard and shall not include any
obligation to obtain any extraordinary waivers, consents or approvals to loan
agreements, leases or other contracts or to agree to an adverse modification of
the terms of any of such documents, to prepay or incur additional obligations to
any other parties or to incur or become liable for any other costs or expenses.

     7.12 Recapitalization Accounting Treatment. Each of the Company, Parent and
MergerCo shall use its reasonable best efforts to cause the Transactions,
including the Merger, to be accounted for as a recapitalization and such
accounting treatment to be accepted by their respective accountants and by the
SEC, and each of the Company, Parent and MergerCo agrees that it shall not take
or omit to take any action that would cause such accounting treatment not to be
obtained.

     7.13 Delisting. Each of the parties hereto agrees to cooperate with each
other in taking, or causing to be taken, all actions necessary to delist the
Common Stock from the American Stock Exchange, provided that such delisting
shall not be effective until after the Effective Time of the Merger.

     7.14 Exchange of Common Stock. Not later than the Effective Time, the
Company shall (i) designate 75,000 shares of Preferred Stock of the Company as
the Series B Stock and (ii) take all such actions as may be necessary to
exchange each share of Common Stock held by the Rollover Stockholders that is
set forth opposite their respective names in Section 6.1(a) of the Company
Disclosure Schedule for 0.2 shares of Series B Stock and complete such exchange,
in each case, pursuant to documentation reasonably acceptable in form and
substance to MergerCo. In effecting such exchange, all fractional shares of
Series B Stock otherwise issuable in connection therewith shall not be issued
but shall be rounded to the nearest number of whole shares of Series B Stock.

     7.15 Solvency Letters. Parent or MergerCo shall engage an appraisal firm,
reasonably satisfactory to the Company, to deliver a letter (the "Solvency
Letter") addressed to the Company, the Company Board, MergerCo and the MergerCo
Board (and on which the Company Board and the MergerCo Board shall be entitled
to rely), which Solvency Letter shall be reasonably satisfactory to the Company
and the Company Board, indicating that immediately after the Effective Time, and
after giving effect to the Merger, the financings contemplated by this Agreement
and any other of the Transactions, the Surviving Corporation will not (i) be
insolvent or (ii) have unreasonably small capital with which to engage in its
business. Notwithstanding anything to the contrary in this Agreement, Parent
and/or MergerCo shall pay all fees, costs and expenses of such appraisal firm in
connection with the preparation and delivery of the Solvency Letter.

     7.16 Purchase of Company Shares. The Company acknowledges that MergerCo may
acquire up to 9.9% of the outstanding shares of Common Stock prior to the
Effective Time in one or more privately negotiated transactions. In connection
with the foregoing, Parent and MergerCo hereby represent and warrant that they
are (a) aware that the United States securities laws prohibit any person who has
material, non-public information concerning a company from purchasing or selling
securities of such company or from communicating such information to any other
person under circumstances in which it is reasonably foreseeable that such
person is likely to purchase or sell such securities, and (b) familiar with the
Exchange Act and that they will not purchase or sell any shares of Common Stock
in contravention of the Exchange Act, including, without limitation, Rule 10b-5
thereunder. Each of Parent and MergerCo agrees that it shall indemnify and hold
harmless the Company and each of its directors, officers, employees and agents
against any losses, claims, damages, liabilities, costs, expenses (including
reasonable attorneys' fees and expenses), judgments, fines and amounts paid in
settlement in connection with any threatened or actual claim, action,

                                      A-25

suit, proceeding or investigation, whether civil, criminal or administrative,
arising out of or relating to any transactions in the Common Stock contemplated
by the first sentence of this Section 7.16.

          (d) No Injunctions, Orders or Restraints; Illegality. No preliminary
     or permanent injunction or other order, decree or ruling issued by a court
     of competent jurisdiction or by a governmental, regulatory or
     administrative agency or commission (an "Injunction") nor any statute,
     rule, regulation or executive order promulgated or enacted by any
     governmental authority shall be in effect which would (i) make the
     consummation of the Merger illegal, or (ii) otherwise restrict, prevent or
     prohibit the consummation of any of the Transactions, including the Merger.

          (e) Solvency Letter. Each of the Company Board and the MergerCo Board

          (a) Representations and Warranties. Those representations and
     warranties of the Company set forth in this Agreement which are qualified
     by materiality or a Company Material Adverse Effect or words of similar
     effect shall be true and correct as of the date of this Agreement and as of
     the Closing Date as though made on and as of the Closing Date (except to
     the extent such representations and warranties expressly relate to a
     specific date, in which case such representations and warranties shall be
     true and correct as of such date), and those representations and warranties
     of the Company set forth in this Agreement which are not so qualified shall
     be true and correct in all material respects as of the date of this
     Agreement and as of the Closing Date as though made on and as of the
     Closing Date (except to the extent such representations and warranties
     expressly relate to a specific date, in which case such representations and
     warranties shall be true and correct in all material respects as of such
     date). Notwithstanding the foregoing, the representations and warranties of
     the Company set forth in Section 5.3 shall be true and correct on the date
     of this Agreement and as of the Closing Date as though made on and as of
     the Closing Date (except to the extent such representations and warranties

<PAGE>   113

     identified by MergerCo after the date of this Agreement shall have been
     obtained or made, except, in the case of clause (ii) hereof, where the
     failure to have obtained or made any such consent, authorization, order,
     approval, filing or registration, would not reasonably be expected to have
     a Company Material Adverse Effect.

          (d) No Injunction. There shall not have been entered any order in any
     action or proceeding by any state or federal government or governmental
     authority or by any United States or state court of competent jurisdiction
     (a "Governmental Entity") which prohibits or limits the ownership or
     operation by the Company (or any of the Company Subsidiaries) of any
     portion of the Company's or the Company Subsidiaries' business, properties
     or assets which is material to the Company and the Company Subsidiaries as
     a whole, or compels the Company (or any Company Subsidiary) to dispose of
     or hold separate any portion of the Company's or the Company Subsidiaries'
     business, properties or assets which is material to the Company and the
     Company Subsidiaries as a whole.

          (e) No Company Material Adverse Change. There shall not have occurred
     any material adverse change in the business, assets, condition (financial
     or otherwise) or results of operations of the Company and the Company
     Subsidiaries taken as a whole nor any event or other circumstance which
     would, individually or in the aggregate, reasonably be expected to result
     in any such material adverse change.

          (f) No Financing Material Adverse Change. There shall not have
     occurred any material disruption or material adverse change in the banking,
     financial or capital markets generally or in the market for senior credit
     facilities or for new issuances of high yield securities which has caused
     either of the Lenders to withdraw its commitment to provide financing as
     contemplated by the Financing Letters.

          (g) Dissenting Shares. As of immediately prior to the Effective Time,
     no more than 5% of the outstanding shares of Common Stock shall have taken
     actions to assert dissenter's rights under Chapter 156B of the MBCL.

          (h) Accounting Treatment. The Proxy Statement shall contain a
     statement to the effect that the Merger shall be treated as a
     recapitalization for accounting purposes and the SEC shall not have
     disapproved such statement in the Proxy Statement.

          (i) Governmental Litigation. There shall not be pending any action,
     claim, proceeding or investigation instituted by any Governmental Entity
     challenging or prohibiting the consummation of the Merger and the
     Transactions.

          (j) Exchange Complete. The exchange contemplated by Section 7.14
     hereof shall have been completed to the reasonable satisfaction of
     MergerCo.

          (k) Indebtedness. On the Closing Date the Company shall have no more
     than $13,000,000 of Net Indebtedness as reflected in a certificate signed
     by the Chief Financial Officer of the Company in form and substance
     reasonably satisfactory to MergerCo. For purposes of this Section 8.2(k),
     "Net Indebtedness" shall mean all obligations of the Company and the
     Company Subsidiaries for borrowed money (including the current portion
     thereof) or evidenced by a bond, note, debenture or similar instrument,
     including without limitation, all obligations arising under the credit
     facility identified in Section 5.6 of the Company Disclosure Schedule,
     minus all cash and cash equivalents of the Company and the Company
     Subsidiaries. Furthermore, for purposes of determining the Company's Net
     Indebtedness under this Section 8.2(k), (i) all checks deposited by the
     Company on or prior to the Closing Date, even if such checks have not
     "cleared" the bank or financial institution into which such checks were
     deposited, shall be deemed to be an increase in "cash", and (ii) all checks
     issued by the Company on or prior to the Closing Date, even if such checks
     have not been "cashed" by the recipients thereof on or prior to the Closing
     Date, shall be deemed to be a decrease in "cash." Notwithstanding the
     foregoing, the term "Net Indebtedness" shall not include any obligations of
     the Company or any Company Subsidiary under any letters of credit.

                                      A-27

          (l) Officer's Certificate. The Company shall have furnished MergerCo

to effect the Merger is further subject to the following conditions:

          (a) Representations and Warranties. Those representations and
     warranties of Parent and MergerCo set forth in this Agreement which are
     qualified by materiality or a Parent Material Adverse Effect or words of
     similar effect shall be true and correct as of the date of this Agreement
     and as of the Closing Date as though made on and as of the Closing Date
     (except to the extent such representations and warranties expressly relate
     to a specific date, in which case such representations shall be true and
     correct as of such date), and those representations and warranties of
     Parent and MergerCo set forth in this Agreement which are not so qualified
     shall be true and correct in all material respects as of the date of this
     Agreement and as of the Closing Date as though made on the Closing Date
     (except to the extent such representations and warranties expressly relate
     to a specific date, in which case such representations and warranties shall
     be true and correct in all material respects as of such date).

          (b) Performance of Obligations of Parent and MergerCo. Each of Parent
     and MergerCo shall have performed all obligations required to be performed
     by it under this Agreement, including, without limitation, the covenants
     contained in Articles 6 and 7 hereof, except where any failure to perform
     would, individually or in the aggregate, not materially impair or
     significantly delay the ability of the Company to consummate the Merger.

          (c) MergerCo Officer's Certificate. MergerCo shall have furnished the
     Company with a certificate dated as of the Closing Date signed on its
     behalf by an executive officer to the effect that the conditions to be
     satisfied by MergerCo set forth in Sections 8.1 and 8.3 have been
     satisfied.

          (d) Parent Officer's Certificate. Parent shall have furnished the
     Company with a certificate dated as of the Closing Date signed on its
     behalf by an executive officer to the effect that the conditions to be
     satisfied by Parent set forth in Sections 8.1 and 8.3 have been satisfied.

                                   ARTICLE IX

                       TERMINATION, AMENDMENT AND WAIVER

     9.1 Termination. This Agreement may be terminated at any time prior to the
Effective Time, whether before or after stockholder approval thereof:

          (a) by the mutual written consent of MergerCo and the Company.

          (b) by either of the Company or MergerCo:

             (i) if the stockholders of the Company shall have failed to give
        the required approval at the Special Meeting (including any adjournment
        or postponement thereof); or

             (ii) if any Governmental Entity shall have issued an Injunction or
        taken any other action (which Injunction or other action the parties
        hereto shall use their reasonable best efforts to lift), which
        permanently restrains, enjoins or otherwise prohibits the Merger, and
        such Injunction shall have become final and non-appealable; or

             (iii) if, without any material breach by the terminating party of
        its obligations under this Agreement, the Merger shall not have occurred
        on or before November 30, 1999.

          (c) by the Company:

             (i) in connection with entering into a definitive agreement to
        effect a Superior Proposal in accordance with Section 7.5; provided,
        however, that prior to terminating this Agreement pursuant to this
        Section 9.1(c)(i), (A) the Company shall have paid the Liquidated
        Amount, as set forth in

                                      A-28
<PAGE>   115

        Section 9.2(b), and (B) the Company shall have provided MergerCo with
        forty-eight (48) hours' prior written notice of the Company's decision
        to so terminate. Such notice shall indicate in reasonable detail the
        terms and conditions of such Superior Proposal, including, without
        limitation, the amount and form of the proposed consideration and
        whether such Superior Proposal is subject to any material conditions.
        Notwithstanding the foregoing, the Company is not required to disclose
        to Parent or MergerCo the identity of the person making such Superior
        Proposal; or

             (ii) if Parent or MergerCo shall have breached in any material
        respect any of their respective representations, warranties, covenants
        or other agreements contained in this Agreement, which breach cannot be
        or has not been cured within fifteen (15) days after the giving of
        written notice to Parent or MergerCo except, in any case, for such
        breaches which are not reasonably likely to affect adversely Parent's or
        MergerCo's ability to consummate the Merger; or

             (iii) after sixty (60) days following receipt by the Company of a
        Parent Financing Notice.

          (d) by MergerCo:

             (i) if the Company shall have breached in any respect any of its
        representations, warranties or covenants contained in this Agreement,
        which breach cannot be or has not been cured within fifteen (15) days
        after the giving of written notice to the Company except, in any case,
        for breaches of such representations and warranties which are not
        reasonably likely to result in a Company Material Adverse Effect;

             (ii) if the Company Board shall (A) fail to include a
        recommendation in the Proxy Statement of this Agreement and the
        Transactions, including the Merger, (B) withdraw or modify or change, or
        propose or announce any intention to withdraw or modify or change, in a
        manner material and adverse to MergerCo, the approval or recommendation
        by the Company Board of this Agreement or the Transactions, including
        the Merger, (C) approve or recommend or propose to announce any
        intention to approve or recommend any Acquisition Proposal, or (D)
        propose or announce any intention to enter into any agreement (other
        than a confidentiality agreement contemplated by Section 7.5 hereof)
        with respect to an Acquisition Proposal; or

             (iii) after sixty (60) days following delivery by Parent or
        MergerCo to the Company of a Parent Financing Notice.

     9.2 Effect of Termination.

     (a) Subject to Sections 9.2(b) and (d) hereof, in the event of the
termination of this Agreement pursuant to Section 9.1 hereof, this Agreement
shall forthwith become null and void and have no effect, without any liability
on the part of any party hereto or its affiliates, trustees, directors, officers
or stockholders and all rights and obligations of any party hereto shall cease
except for the agreements contained in Section 7.4, the third sentence of
Section 7.16 and Articles 9 and 10; provided, however, that nothing contained in
this Section 9.2(a) shall relieve any party from liability for any fraud or
willful breach of this Agreement.

     (b) The Company shall pay to MergerCo an amount in cash equal to (A)
$5,000,000 (the "Liquidated Amount"), plus (B) the Parent/MergerCo Expenses (as
hereinafter defined) if (W) MergerCo terminates this Agreement under Section
9.1(d)(i) as a result of the Company having wilfully breached its obligations
under Section 7.1(a)(i) or Section 7.1(a)(iii), or (X) the Company terminates
this Agreement pursuant to Section 9.1(c)(i) or (Y) MergerCo terminates this
Agreement pursuant to Section 9.1(d)(ii) or (Z) either the Company or MergerCo
terminates this Agreement pursuant to Section 9.1(b)(i), if, prior to the
Special Meeting, (i) an Acquisition Proposal shall have been made directly to
the Company's stockholders generally or any person shall have publicly announced
an Acquisition Proposal or solicited proxies or consents in opposition to the
Merger and (ii) within nine (9) months immediately following the date of such
termination the Company and the party who shall have made such Acquisition
Proposal or any affiliate thereof enter into a definitive agreement with respect
thereto. Notwithstanding the foregoing, in no event shall the Company be
obligated to pay the Liquidated Amount or the Parent/MergerCo Expenses more than
once. For purposes of this Section 9.2, "Parent/MergerCo Expenses" shall be an
amount equal to the reasonable out-of-pocket costs

                                      A-29
<PAGE>   116

and expenses incurred by Parent and MergerCo in connection with this Agreement
and the Transactions, including without limitation, fees and disbursements of
its outside legal counsel, investment bankers, accountants and other consultants
retained by or on behalf of Parent and MergerCo together with the other
out-of-pocket costs and expenses incurred by Parent and MergerCo in connection
with analyzing and structuring the Transactions, negotiating the terms and
conditions of this Agreement and any other agreements or other documents
relating to the Transactions, arranging financing, conducting due diligence and
other activities related to this Agreement and the Transactions (collectively,
the "Parent/MergerCo Expenses"); provided, however, that the aggregate amount of
all Parent/MergerCo Expenses to be reimbursed by the Company shall not exceed
$1,000,000.

     (c) Any payment of the Liquidated Amount required by Section 9.2(b) hereof
shall be payable by the Company to MergerCo by wire transfer of immediately
available funds (i) in the case of clause (W) or (Y) thereof, within three (3)
business days after the date of termination, (ii) in the case of clause (Z)
thereof, within three (3) business days after the date of entering into such
definitive agreement, and (iii) in the case of clause (X) thereof, prior to
terminating this Agreement pursuant to Section 9.1(c)(i) hereof, in any such
case to an account designated by MergerCo. Any payment of the Parent/MergerCo
Expenses required by Section 9.2(b) hereof shall be payable by the Company to
MergerCo by wire transfer of immediately available funds promptly following
receipt by the Company of reasonable documentation of all Parent/ MergerCo
Expenses.

     (d) Notwithstanding anything to the contrary in this Agreement, Parent and
MergerCo hereto expressly acknowledge and agree that, with respect to any
termination of this Agreement pursuant to Section 9.1(c)(i) or Section
9.1(d)(ii) hereof, or Section 9.1(b)(i) or Section 9.1(d)(i) hereof in
circumstances where the Liquidated Amount and the Parent/MergerCo Expenses are
payable in accordance with Section 9.2(b) hereof, the payment of the Liquidated
Amount and the Parent/MergerCo Expenses shall constitute liquidated damages with
respect to any claim for damages or any other claim which Parent or MergerCo
would otherwise be entitled to assert against the Company or any of the Company
Subsidiaries or any of their respective assets, or against any of their
respective directors, officers, employees, partners, managers, members or
shareholders, with respect to this Agreement and the Transactions and shall
constitute the sole and exclusive remedy available to Parent and MergerCo. The
parties hereto expressly acknowledge and agree that, in light of the difficulty
of accurately determining actual damages with respect to the foregoing upon any
termination of this Agreement pursuant to Section 9.1(c)(i) or Section
9.1(d)(ii) hereof, or Section 9.1(b)(i) or Section 9.1(d)(i) hereof in
circumstances where the Liquidated Amount and the Parent/MergerCo Expenses are
payable in accordance with Section 9.2(b) hereof, the rights to payment under
Section 9.2(b): (i) constitute a reasonable estimate of the damages that will be
suffered by reason of any such proposed or actual termination of this Agreement
pursuant to Section 9.1(c)(i) or Section 9.1(d)(ii) hereof, or Section 9.1(b)(i)
or Section 9.1(d)(i) hereof in circumstances where the Liquidated Amount and the
Parent/MergerCo Expenses are payable in accordance with Section 9.2(b) hereof,
and (ii) shall be in full and complete satisfaction of any and all damages
arising as a result of the foregoing. Except for nonpayment of the amounts set
forth in Section 9.2(b), Parent and MergerCo hereby agree that, upon any
termination of this Agreement pursuant to Section 9.1(c)(i) or Section
9.1(d)(ii) hereof, or Section 9.1(b)(i) or Section 9.1(d)(i) hereof in
circumstances where the Liquidated Amount and the Parent/MergerCo Expenses are
payable in accordance with Section 9.2(b) hereof, in no event shall Parent or
MergerCo (A) seek to obtain any recovery or judgment against the Company or any
of the Company Subsidiaries or any of their respective assets, or against any of
their respective directors, officers, employees, partners, managers, members or
shareholders, and (B) be entitled to seek or obtain any other damages of any
kind, including, without limitation, consequential, indirect or punitive
damages.

     9.3 Amendment. This Agreement may be amended by the parties hereto by an
instrument in writing signed on behalf of each of the parties hereto at any time
before or after any approval hereof by the stockholders of the Company and
MergerCo, but in any event following authorization by the MergerCo Board and the
Company Board; provided, however, that after any such stockholder approval, no
amendment shall be made which by law requires further approval by stockholders
without obtaining such approval.

     9.4 Extension; Waiver. At any time prior to the Closing, the parties hereto
may, to the extent legally allowed, (i) extend the time for the performance of
any of the obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto and (iii) waive compliance with any of the
agreements or conditions contained herein. Any agreement on the part of a party
hereto to any such extension or waiver shall be valid only if set forth in a
written instrument signed on behalf of such party.

     10.2 Interpretation. When a reference is made in this Agreement to a
subsidiary or subsidiaries of Parent, MergerCo or the Company, the word
"Subsidiary" means any corporation more than 50% of whose outstanding voting
securities, or any partnership, joint venture or other entity more than 50% of
whose total equity interest, is directly or indirectly owned by Parent, MergerCo
or the Company, as the case may be. The headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     10.3 Non-Survival of Representations, Warranties, Covenants and
Agreements. Except for Sections 7.6, 7.16 and 10.7 none of the representations,
warranties, covenants and agreements contained in this Agreement or in any

Time, and thereafter

                                      A-31
<PAGE>   118

there shall be no liability on the part of either Parent, MergerCo or the
Company or any of their respective officers, directors or stockholders in
respect thereof. Except as expressly set forth in this Agreement, there are no
representations or warranties of any party hereto, express or implied.

     10.4 Miscellaneous. This Agreement (i) constitutes, together with the
Confidentiality Agreement, the Company Disclosure Letter and the Parent and
MergerCo Disclosure Schedule, the entire agreement and supersedes all of the
prior agreements and understandings, both written and oral, among the parties,
or any of them, with respect to the subject matter hereof, (ii) shall be binding
upon and inure to the benefits of the parties hereto and their respective
successors and assigns and is not intended to confer upon any other person
(except as set forth below) any rights or remedies hereunder and (iii) may be
executed in two or more counterparts which together shall constitute a single
agreement. Section 7.6 is intended to be for the benefit of those persons
described therein and the covenants contained therein may be enforced by such
persons. The parties hereto agree that irreparable damage would occur in the
event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in the Massachusetts Courts (as hereinafter
defined), this being in addition to any other remedy to which they are entitled
at law or in equity.

     10.5 Assignment. Except as expressly permitted by the terms hereof, neither
this Agreement nor any of the rights, interests or obligations hereunder shall
be assigned by any of the parties hereto without the prior written consent of
the other parties.

     10.6 Severability. If any provision of this Agreement, or the application
thereof to any person or circumstance is held invalid or unenforceable, the
remainder of this Agreement, and the application of such provision to other
persons or circumstances, shall not be affected thereby, and to such end, the
provisions of this Agreement are agreed to be severable.

     10.7 Choice of Law/Consent to Jurisdiction. All disputes, claims or
controversies arising out of or relating to this Agreement, or the negotiation,
validity or performance of this Agreement, or the Transactions shall be governed
by and construed in accordance with the laws of the Commonwealth of
Massachusetts without regard to its rules of conflict of laws. Each of the
Company, Parent and MergerCo hereby irrevocably and unconditionally consents to
submit to the sole and exclusive jurisdiction of the courts of the Commonwealth
of Massachusetts and of the United States District Court for the District of
Massachusetts (the "Massachusetts Courts") for any litigation arising out of or
relating to this Agreement, or the negotiation, validity or performance of this
Agreement, or the Transactions (and agrees not to commence any litigation
relating thereto except in such courts), waives any objection to the laying of
venue of any such litigation in the Massachusetts Courts and agrees not to plead
or claim in any Massachusetts Court that such litigation brought therein has
been brought in any inconvenient forum. Each of the parties hereto agrees, (a)
to the extent such party is not otherwise subject to service of process in the
Commonwealth of Massachusetts, to appoint and maintain an agent in the
Commonwealth of Massachusetts as such party's agent for acceptance of legal
process, and (b) that service of process may also be made on such party by
prepaid certified mail with a proof of mailing receipt validated by the United
States Postal Service constituting evidence of valid service. Service made
pursuant to (a) or (b) above shall have the same legal force and effect as if
served upon such party personally within the Commonwealth of Massachusetts. For
purposes of implementing the parties' agreement to appoint and maintain an agent
for service of process in the Commonwealth of Massachusetts, each of Parent and
MergerCo does hereby appoint CT Corporation, 2 Oliver Street, Boston,
Massachusetts 02109, as such agent.

     10.8 No Agreement Until Executed. Irrespective of negotiations among the
parties or the exchanging of drafts of this Agreement, this Agreement shall not
constitute or be deemed to evidence a contract, agreement, arrangement or
understanding among the parties hereto unless and until (i) the Board of
Directors of the Company has approved, for purposes of Chapter 110F of the MGL
and any applicable provision of the Articles of Organization, the terms of this
Agreement, and (ii) this Agreement is executed by the parties hereto.

     IN WITNESS WHEREOF, Parent, MergerCo and the Company have caused this
Agreement to be executed as of the date first written above by their respective
officers thereunto duly authorized.

                                   APPENDIX B

CONFIDENTIAL

May 6, 1999

Board of Directors
Instron Corporation
100 Royall Street
Canton, MA 02021-1089

Gentlemen:

     Instron Corporation (the "Company") has requested that The Beacon Group
Capital Services, LLC ("Beacon") deliver to the Company's Board of Directors
Beacon's opinion concerning the fairness from a financial point of view to the
holders of outstanding shares of the Company's Common Stock, par value $1.00 per
share, (the "Shares") other than holders of Excepted Shares, as hereinafter
defined, of the consideration to be received by those holders in the merger
transaction (the "Merger") provided for by an Agreement and Plan of Merger,
dated as of May 6, 1999, (the "Agreement") by and among the Company, Kirtland
Capital Partners III L.P. ("Parent") and ISN Acquisition Corp. ("MergerCo"), a
corporation formed by, and a wholly-owned subsidiary of, Parent.

     The Agreement provides, among other things, that (i) MergerCo will be
merged with and into the Company, (ii) the Company will be the surviving
corporation (the "Surviving Corporation"), and (iii) each outstanding Share,
other than (a) Shares held by the Company as treasury stock, by any wholly owned
subsidiary of the Company or by MergerCo, (b) Shares exchanged for Series B
Preferred Stock, par value $1.00 per share, of the Company prior to the Merger
and (c) Dissenting Shares, as defined in the Agreement (collectively, the
"Excepted Shares"), will be converted into the right to receive $22 in cash,
without interest. The Merger is expected to be considered by the stockholders of
the Company at a special stockholders meeting to be held as soon as practicable
and, if approved by the stockholders at that meeting, consummated on or shortly
after that meeting.

     As part of its strategic advisory business, Beacon engages in the valuation
of businesses and their securities in connection with mergers and acquisitions,
financings, private placements, principal investments and other purposes. In
this regard, Beacon has been serving as a financial advisor to the Company and
participated in certain of the negotiations relating to the Agreement and the
Merger. Beacon is also familiar with Parent and two Beacon Managing Directors
are limited partner investors in Parent.

     In connection with its opinion, Beacon reviewed, among other things, the
Agreement, Annual Reports to stockholders and Annual Reports on Form 10-K of the
Company for the five years ended December 31, 1998, certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company, certain other
communications from the Company to stockholders, certain internal financial
analyses and forecasts for the Company prepared by its management and the
potential pro forma impact of the Merger on the Surviving Corporation. Beacon
also held discussions with members of senior management of the Company regarding
the past and current business, operations and financial condition and the future
prospects of the Company, reviewed the reported price and trading activity of
the Shares, compared certain financial and stock market information concerning
the Company with similar information concerning certain other companies the
securities of which are publicly traded, reviewed the financial terms of certain
recent business combinations in industries and markets Beacon deemed relevant
and performed other studies and analyses that Beacon considered appropriate.

     For purposes of its opinion, Beacon assumed and relied without independent
verification on the accuracy and completeness of the financial and other
information reviewed by it. Beacon did not make an independent evaluation or
appraisal of the assets and liabilities of the Company or any of its
subsidiaries and was not furnished with any such evaluation or appraisal.

                                       B-1
<PAGE>   121

     Beacon's opinion is provided for the information of the Board of Directors
of the Company in connection with its consideration of the Agreement and the
Merger and does not constitute a recommendation to any stockholder of the
Company as to how that stockholder should vote in connection with the Agreement
and the Merger. Beacon's opinion is necessarily based on economic, market,
financial and other conditions as they exist on, and could be evaluated as of,
the date hereof.

     Based on and subject to the foregoing and other matters Beacon considers
relevant, it is Beacon's opinion that, as of the date hereof, the consideration
to be received by holders of Shares, other than Excepted Shares, is fair from a
financial point of view to such holders.

Very truly yours,

                                   APPENDIX C

                     MASSACHUSETTS BUSINESS CORPORATION LAW
                                  CHAPTER 156B

     85. A stockholder in any corporation organized under the laws of
Massachusetts which shall have duly voted to consolidate or merge with another
corporation or corporations under the provisions of sections seventy-eight or
seventy-nine who objects to such consolidation or merger may demand payment for
his stock from the resulting or surviving corporation and an appraisal in
accordance with the provisions of sections eighty-six to ninety-eight,
inclusive, and such stockholder and the resulting or surviving corporation shall
have the rights and duties and follow the procedure set forth in those sections.
This section shall not apply to the holders of any shares of stock of a
constituent corporation surviving a merger if, as permitted by subsection (c) of
section seventy-eight, the merger did not require for its approval a vote of the
stockholders of the surviving corporation.

     86. If a corporation proposes to take a corporate action as to which any
section of this chapter provides that a stockholder who objects to such action
shall have the right to demand payment for his shares and an appraisal thereof,
sections eighty-seven to ninety-eight, inclusive, shall apply except as
otherwise specifically provided in any section of this chapter. Except as
provided in sections eighty-two and eighty-three, no stockholder shall have such
right unless (1) he files with the corporation before the taking of the vote of
the shareholders on such corporate action, written objection to the proposed
action stating that he intends to demand payment for his shares if the action is
taken and (2) his shares are not voted in favor of the proposed action.

     87. The notice of the meeting of stockholders at which the approval of such
proposed action is to be considered shall contain a statement of the rights of
objecting stockholders. The giving of such notice shall not be deemed to create
any rights in any stockholder receiving the same to demand payment for his
stock, and the directors may authorize the inclusion in any such notice of a
statement of opinion by the management as to the existence or non-existence of
the right of the stockholders to demand payment for their stock on account of
the proposed corporate action. The notice may be in such form as the directors
or officers calling the meeting deem advisable, but the following form of notice
shall be sufficient to comply with this section:

          "If the action proposed is approved by the stockholders at the meeting
     and effected by the corporation, any stockholder (1) who files with the
     corporation before the taking of the vote on the approval of such action,
     written objection to the proposed action stating that he intends to demand
     payment for his shares if the action is taken and (2) whose shares are not
     voted in favor of such action has or may have the right to demand in
     writing from the corporation (or, in the case of a consolidation or merger,
     the name of the resulting or surviving corporation shall be inserted),
     within twenty days after the date of mailing to him of notice in writing
     that the corporate action has become effective, payment for his shares and
     an appraisal of the value thereof. Such corporation and any such
     stockholder shall in such cases have the rights and duties and shall follow
     the procedure set forth in sections 88 to 98, inclusive, of chapter 156B of
     the General Laws of Massachusetts."

     88. The corporation taking such action, or in the case of a merger or
consolidation the surviving or resulting corporation, shall, within ten days
after the date on which such corporate action became effective, notify each
stockholder who filed written objection meeting the requirements of section
eighty-six and whose shares were not voted in favor of the approval of such
action, that the action approved at the meeting of the corporation of which he
is a stockholder has become effective. The giving of such notice shall not be
deemed to create any rights in any stockholder receiving the same to demand
payment for his stock. The notice shall be sent by registered or certified mail,
addressed to the stockholder at his last known address as it appears in the
records of the corporation.

     89. If within twenty days after the date of mailing of a notice under
subsection (e) of section eighty-two, subsection (f) of section eighty-three, or
section eighty-eight any stockholder to whom the corporation was required to
give such notice shall demand in writing from the corporation taking such
action, or in the

                                       C-1
<PAGE>   123

case of a consolidation or merger from the resulting or surviving corporation,
payment for his stock, the corporation upon which such demand is made shall pay
to him the fair value of his stock within thirty days after the expiration of
the period during which such demand may be made.

     90. If during the period of thirty days provided for in section eighty-nine
the corporation upon which such demand is made and any such objecting
stockholder fail to agree as to the value of such stock, such corporation or any
such stockholder may within four months after the expiration of such thirty-day
period demand a determination of the value of the stock of all such objecting
stockholders by a bill in equity filed in the superior court in the county where
the corporation in which such objecting stockholder held stock had or has its
principal office in the commonwealth.

     91. If the bill is filed by the corporation, it shall name as parties
respondent all stockholders who have demanded payment for their shares and with
whom the corporation has not reached agreement as to the value thereof. If the
bill is filed by a stockholder, he shall bring the bill in his own behalf and in
behalf of all other stockholders who have demanded payment for their shares and
with whom the corporation has not reached agreement as to the value thereof, and
service of the bill shall be made upon the corporation by subpoena with a copy
of the bill annexed. The corporation shall file with its answer a duly verified
list of all such other stockholders, and such stockholders shall thereupon be
deemed to have been added as parties to the bill. The corporation shall give
notice in such form and returnable on such date as the court shall order to each
stockholder party to the bill by registered or certified mail, addressed to the
last known address of such stockholder as shown in the records of the
corporation, and the court may order such additional notice by publication or
otherwise as it deems advisable. Each stockholder who makes demand as provided
in section eighty-nine shall be deemed to have consented to the provisions of
this section relating to notice, and the giving of notice by the corporation to
any such stockholder in compliance with the order of the court shall be a
sufficient service of process on him. Failure to give notice to any stockholder
making demand shall not invalidate the proceedings as to other stockholders to
whom notice was properly given, and the court may at any time before the entry
of a final decree make supplementary orders of notice.

     92. After hearing the court shall enter a decree determining the fair value
of the stock of those stockholders who have become entitled to the valuation of
and payment for their shares, and shall order the corporation to make payment of
such value, together with interest, if any, as hereinafter provided, to the
stockholders entitled thereto upon the transfer by them to the corporation of
the certificates representing such stock if certificated or if uncertificated,
upon receipt of an instruction transferring such stock to the corporation. For
this purpose, the value of the shares shall be determined as of the day
preceding the date of the vote approving the proposed corporate action and shall
be exclusive of any element of value arising from the expectation or
accomplishment of the proposed corporate action.

     93. The court in its discretion may refer the bill or any question arising
thereunder to a special master to hear the parties, make findings and report the
same to the court, all in accordance with the usual practice in suits in equity
in the superior court.

     94. On motion the court may order stockholder parties to the bill to submit
their certificates of stock to the corporation for notation thereon of the
pendency of the bill, and may order the corporation to note such pendency in its
records with respect to any uncertificated shares held by such stockholder
parties, and may on motion dismiss the bill as to any stockholder who fails to
comply with such order.

     95. The costs of the bill, including the reasonable compensation and
expenses of any master appointed by the court, but exclusive of fees of counsel
or of experts retained by any party, shall be determined by the court and taxed
upon the parties to the bill, or any of them, in such manner as appears to be
equitable, except that all costs of giving notice to stockholders as provided in
this chapter shall be paid by the corporation. Interest shall be paid upon any
award from the date of the vote approving the proposed corporate action, and the
court may on application of any interested party determine the amount of
interest to be paid in the case of any stockholder.

     96. Any stockholder who has demanded payment for his stock as provided in
this chapter shall not thereafter be entitled to notice of any meeting of
stockholders or to vote such stock for any purpose and shall

                                       C-2
<PAGE>   124

not be entitled to the payment of dividends or other distribution on the stock
(except dividends or other distributions payable to stockholders of record at a
date which is prior to the date of the vote approving the proposed corporate
action) unless:

     (1) A bill shall not be filed within the time provided in section ninety;

     (2) A bill, if filed, shall be dismissed as to such stockholder; or

     (3) Such stockholder shall with the written approval of the corporation, or
         in the case of a consolidation or merger, the resulting or surviving
         corporation, deliver to it a written withdrawal of his objections to
         and an acceptance of such corporate action.

     Notwithstanding the provisions of clauses (1) to (3), inclusive, said
stockholder shall have only the rights of a stockholder who did not so demand
payment for his stock as provided in this chapter.

     97. The shares of the corporation paid for by the corporation pursuant to
the provisions of this chapter shall have the status of treasury stock or in the
case of a consolidation or merger the shares or the securities of the resulting
or surviving corporation into which the shares of such objecting stockholder
would have been converted had he not objected to such consolidation or merger
shall have the status of treasury stock or securities.

     98. The enforcement by a stockholder of his right to receive payment for
his shares in the manner provided in this chapter shall be an exclusive remedy
except that this chapter shall not exclude the right of such stockholder to
bring or maintain an appropriate proceeding to obtain relief on the ground that
such corporate action will be or is illegal or fraudulent as to him.
