                                                               December   , 1995
 
Dear Stockholder:
 
     You are cordially invited to attend a special meeting of stockholders to be
held at 10:00 a.m., Eastern Time on January   , 1996 at the offices of Kevlin at
the address set forth above.
 
     At this meeting, you will be asked to approve the proposed merger of Kevlin
into a subsidiary of Chelton Communication Systems, Inc. ("Chelton"). Chelton is
a Delaware corporation engaged in the manufacture and sale of microwave
waveguides and assorted electronics for application in radar and communication
systems. If the merger is consummated, Kevlin will become a wholly-owned
subsidiary of Chelton and Kevlin stockholders will receive $4.54 in cash for
each share of Kevlin Common Stock.
 
     Details about the proposed merger are included in the attached Proxy
Statement. I urge you to read these materials carefully. Approval of this
important matter will require the affirmative vote of the holders of two-thirds
of the common stock of Kevlin outstanding on December   , 1995, the record date
for the special meeting.
 
     Your Board of Directors believes that the merger is in the best interests
of the stockholders of Kevlin and has unanimously approved the merger. In
arriving at its decision, your Board of Directors carefully evaluated the
consideration to be received by Kevlin's stockholders in the merger as a means
of maximizing stockholder value.
 
     We appreciate the loyalty and support our stockholders have demonstrated
over the years. We hope that you will continue this support by voting FOR the
proposal now. I intend to vote FOR the proposal, and recommend that all
stockholders do the same. Regardless of the number of shares you may own, it is
important that your shares be represented at the meeting. Accordingly, please
promptly sign and return your proxy card in the envelope provided whether or not
you plan to attend the meeting. If you attend the meeting, you may vote in
person whether or not you have previously returned your proxy.
 
                                          Sincerely,
 
                                          Jonathan D. Donaldson
                                          Chairman of the Board
 
    NOTE: PLEASE DO NOT SEND IN YOUR STOCK CERTIFICATES AT THE PRESENT TIME.

                               KEVLIN CORPORATION
                                5 CORNELL PLACE
                        WILMINGTON, MASSACHUSETTS 01887
 
                                PROXY STATEMENT
 
                     FOR A SPECIAL MEETING OF STOCKHOLDERS
                         TO BE HELD ON JANUARY   , 1996
 
     This Proxy Statement (the "Proxy Statement") relates to the proposed
acquisition of Kevlin Corporation ("Kevlin"), a Massachusetts corporation, by
Chelton Communications Systems, Inc. ("Chelton"), a Delaware corporation,
pursuant to the terms of an Agreement and Plan of Merger, dated as of December
6, 1995 (the "Merger Agreement"). It is being furnished to stockholders of
Kevlin in connection with the solicitation of proxies by the Board of Directors
of Kevlin for the special meeting of stockholders to be held on January   , 1996
at 10:00 a.m., at the offices of Kevlin and any adjournments or postponements
thereof (the "Special Meeting"). Only stockholders of record at the close of
business on December   , 1995 (the "Record Date") will be entitled to vote at
the Special Meeting. This Proxy Statement and the enclosed form of proxy are
first being mailed or delivered to stockholders on or about             , 1995.
 
     At the Special Meeting, Kevlin will present a proposal to adopt the Merger
Agreement. If the Merger Agreement is adopted and the other conditions set forth
in the Merger Agreement are satisfied, Kevlin Acquisition Corp. ("Newco"), a
wholly-owned subsidiary of Chelton, will be merged with and into Kevlin (the
"Merger"), with the result that Kevlin will become a wholly-owned subsidiary of
Chelton. Each outstanding share of the common stock, $0.10 par value, of Kevlin
(the "Common Stock"), other than shares as to which appraisal rights have been
perfected under Section 85 of the Massachusetts General Corporation Law, will be
converted into the right to receive $4.54 in cash (the "Merger Consideration").
 
     Under Massachusetts law, Kevlin stockholders have certain dissenters'
rights of appraisal in connection with the Merger. See "The
Acquisition -- Kevlin Stockholder Appraisal Rights."
 
     On the Record Date, Kevlin had outstanding      shares of Common Stock,
which is its only outstanding class of capital stock. Each share of Common Stock
is entitled to one vote for each matter submitted to a vote at the Special
Meeting. A majority in interest of the outstanding Common Stock, represented at
the Special Meeting in person or by proxy, constitutes a quorum for the
transaction of business. The affirmative vote in favor of adopting the Merger
Agreement by two-thirds of the outstanding Common Stock is a condition to both
Kevlin's and Chelton's obligation to consummate the Merger.
 
     The authority granted by an executed proxy may be revoked at any time
before its exercise by filing with the Clerk of Kevlin a written revocation or a
duly executed proxy bearing a later date or by voting in person at the Special
Meeting. Shares represented by valid proxies will be voted in accordance with
the specifications in the proxies. If no specifications are made, the proxies
will be voted to approve the proposals set forth in the proxy.
 
     The date of this Proxy Statement is             , 1995, and it is first
being mailed or delivered to Kevlin stockholders on or about that date.

                               CORPORATE ACTIONS
 
NEWCO STOCKHOLDER CONSENT
 
     Chelton, as the holder of all of the outstanding shares of common stock of
Newco, intends to approve the Merger by written consent. The written consent
will constitute the corporate action required under Massachusetts law.
 
SPECIAL MEETING
 
     Time, Place and Purpose.  The Special Meeting will be held on January   ,
1996, at 10:00 a.m. Eastern Time, at the offices of Kevlin, 5 Cornell Place,
Wilmington, Massachusetts 01887. At the Special Meeting, the stockholders of 
Kevlin will be asked to approve and adopt the Merger Agreement.
 
     Required Vote.  The affirmative vote of the holders of two-thirds of the
shares of Kevlin Common Stock outstanding as of the Record Date (as defined
below) is required to approve and adopt the Merger Agreement. Such approval and
adoption is a condition to consummation of the Merger. Votes withheld,
abstentions and broker non-votes (where a broker or nominee does not exercise
discretionary authority to vote on a matter) are counted for purposes of
determining the presence or absence of a quorum for the transaction of business,
but, since the affirmative vote of two-thirds of outstanding shares is required
to approve the Merger Agreement, such actions will have the effect of a negative
vote. See "Corporate Actions -- Kevlin
 
                                        5

Stockholder Meeting." The officers and directors of Kevlin and their affiliates
hold shares of Kevlin Common Stock representing approximately   % of the
outstanding shares of Kevlin Common Stock (excluding shares which such persons
have the right to acquire upon the exercise of stock options).
 
     Record Date and Stockholder Information.  The Board of Directors of Kevlin
has fixed the close of business on December   , 1995 as the record date for
determining stockholders entitled to notice of and to vote at the Special
Meeting (the "Record Date"). At the close of business on the Record Date,
            shares of Kevlin Common Stock were outstanding. The directors and
executive officers of Chelton beneficially own no shares of Kevlin Common Stock,
and Chelton and its subsidiaries own no such shares. See "Corporate
Actions -- Kevlin Stockholder Meeting."
 
                                THE ACQUISITION
 
MERGER
 
     This Proxy Statement relates to the proposed acquisition of Kevlin by
Chelton to be effected by the Merger of Newco with and into Kevlin. In the
Merger, each share of Kevlin Common Stock outstanding as of the Effective Time,
as defined below, will be converted into the right to receive $4.54 in cash.
Upon consummation of the Merger, Kevlin will be the surviving corporation in the
Merger (the "Surviving Corporation") and will conduct the business of Kevlin as
a whollyowned subsidiary of Chelton.
 
     The Merger will become effective as soon as practicable after satisfaction
or waiver of all conditions to the Merger and at the time and on the date
Articles of Merger are duly filed with the Secretary of the Commonwealth of
Massachusetts, or at such later time and date as is specified as the effective
time of the Merger therein (the "Effective Time"). See "The
Acquisition -- Merger and Effective Time." Assuming all conditions to the Merger
are met, or waived where permissible, it is expected that the Effective Time
will occur on January   , 1996, or as soon thereafter as practicable.
 
PAYMENT FOR KEVLIN SECURITIES
 
     As a result of the Merger, at the Effective Time all outstanding shares of
Kevlin Common Stock (other than shares of holders who perfect dissenters' rights
under Massachusetts law ("Kevlin Dissenting Shares"), and shares held by any
subsidiary of Kevlin) will be converted into the right to receive $4.54 in cash
(the "Merger Consideration").
 
TREATMENT OF OPTIONS
 
     Chelton's obligations under the Merger Agreement are conditioned upon,
among other things, all outstanding options to purchase shares of Kevlin Common
Stock being exercised or terminated at or prior to the closing of the Merger.
Holders of such options will be permitted, prior to the termination of the
option, to pay the exercise price of the option with shares of Common Stock
acquired on exercise, thereby permitting optionholders to exercise their options
prior to termination with the payment of only a nominal amount of cash. Upon the
consummation of the Merger and the payment of the Merger Consideration, each
person who had previously held options and exercised such options as described
in the previous sentence will have received an amount of cash equal to the
difference between the exercise price of the option and the Merger
Consideration. See "The Acquisition -- Treatment of Options."

     Kevlin Common Stock is listed on NASDAQ and designated a Nasdaq National
Market security, trading under the symbol "KVLM". On October 11, 1995, the last

Merger, the high and low sale prices of Kevlin Common Stock as reported by

                                        6
<PAGE>   10
 
the Securities Exchange Act of 1934 (the "Exchange Act") and will, therefore, no
longer be subject to the reporting requirements of the Exchange Act.
 
REASONS FOR THE ACQUISITION
 
  Chelton
 
     Chelton believes that Kevlin's development and sales of rotary couplers for
military and commercial radars and air traffic control ("ATC") systems is a
natural extension of Chelton's air and ground antenna and microwave product
lines. Kevlin's defense, ATC and international markets are well known to
Chelton, and Chelton believes that a synergy will be obtained through combined
sales and marketing efforts, especially in the international arena.
 
  Kevlin
 
     The Board of Directors of Kevlin has unanimously approved the Merger
Agreement and the transactions contemplated thereby and recommends that the
stockholders of Kevlin vote in favor of the adoption of the Merger Agreement.
 
     In evaluating the transaction, the Kevlin Board of Directors was
furnished with and considered the most recent financial statements of Kevlin,
reports from management on management's plans for expansion into additional
related testing markets and reports regarding Kevlin's future financing needs.
After considering the available alternatives and the immediate and foreseeable
prospects for Kevlin, the Board of Directors of Kevlin concluded that the
Merger is in the best interests of the stockholders of Kevlin, that the Merger
offers the greatest immediate and long-term value to the stockholders and that
the Merger provides the best prospect to serve the needs of each other
constituency of Kevlin, including its employees and customers. Specifically,
the Board of Directors concluded that (i) the Merger enhances stockholder value
and liquidity by providing a Merger Consideration that is 182% higher than the
price of the Kevlin Common Stock at the end of fiscal 1995, (ii) the Merger
would enable Kevlin to expand strategically its global presence and diversify
into other markets by combining Kevlin's sales organization with the world-wide
organization of Chelton, and (iii) the Merger has the potential to improve
Kevlin's operational capabilities through Kevlin's association with Chelton and
its affiliates and their management team, additional capital resources and
manufacturing facilities and capabilities. See "The Acquisition -- Kevlin's
Reasons for the Acquisition."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF KEVLIN
 
     THE BOARD OF DIRECTORS OF KEVLIN UNANIMOUSLY RECOMMENDS THAT THE KEVLIN
STOCKHOLDERS VOTE THEIR SHARES OF KEVLIN COMMON STOCK IN FAVOR OF APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT.
 
INTEREST OF CERTAIN PERSONS IN THE MATTER TO BE ACTED UPON
 
     In connection with the Merger, the Board of Directors of Kevlin has
approved a payment, upon the completion of the Merger, to each of the Company's
non-employee directors (Jonathan Donaldson, Howard Mileaf and Carmine Vittoria)
of a specified percentage of the aggregate amount calculated by the application
of the so-called "Lehman Formula" to the aggregate Merger Consideration.
Consequently, if the Merger is completed, Messrs. Donaldson, Mileaf and Vittoria
will receive $215,068, $30,724 and $10,241, respectively, or 84%, 12% and 4%,
respectively, of an aggregate amount of $256,033. See "The
Acquisition -- Interest of Certain Persons in the Matter to be Acted Upon."
 
COVENANTS
 
     Kevlin and Chelton have made certain covenants and agreements with each
other in the Merger Agreement relating to, among other things, (i) the conduct
of Kevlin's business, (ii) access to information, (iii) obtaining necessary
consents, and (iv) the preparation of this Proxy Statement and other matters.
Kevlin has also agreed that it will not enter into negotiations with or solicit
offers from third parties regarding a
 
                                        7
<PAGE>   11
 
potential acquisition of Kevlin, and will notify Chelton promptly of any such
offer received by either of them. See "The Acquisition -- Representations,
Warranties and Covenants."
 
CONDITIONS OF MERGER; TERMINATION
 
     In addition to the approval of the Merger Agreement by the stockholders of
Kevlin, the respective obligations of Chelton and Kevlin to consummate the
Merger are subject to certain conditions, including that (i) all representations
and warranties contained in the Merger Agreement be correct as of the Effective
Time; (ii) certain covenants and agreements contained in the Merger Agreement
have been performed or waived prior to the Effective Time; (iii) the parties
have received the legal opinions and other documents described in the Merger
Agreement; (iv) the absence of litigation against Kevlin or Chelton with respect
to the Merger; and (v) the receipt of all necessary consents to the Merger. See
"The Acquisition -- Conditions of Merger."
 
     The Merger Agreement may be terminated prior to the Effective Time under
certain circumstances, including at the election of the Board of Directors of
Kevlin or Chelton on or after February 28, 1996 if any of the conditions to its
obligation to consummate the Merger has not been fulfilled (provided that the
terminating party is not in material breach of its representation, warranties or
obligation under the Merger Agreement). Either Kevlin or Chelton may be
obligated, upon a termination of the Merger Agreement under certain
circumstances, to reimburse the other party up to $150,000 for expenses incurred
in connection with the Merger. See "The Acquisition -- Termination."
 
BREAKUP AND TERMINATION FEES
 
     If, prior to termination of the Merger Agreement, certain events occur
which could preclude the Merger, Chelton may be obligated to pay a fee of
$1,000,000 (the "Breakup Fee") to Kevlin. Upon termination, Kevlin may under
certain circumstances, be obligated to pay a fee of $1,000,000 (the "Termination
Fee") to Chelton. See "The Acquisition -- Breakup and Termination Fees; No
Solicitation."
 
ACCOUNTING TREATMENT
 
     If the Merger is consummated, Chelton expects to account for the Merger 
using the purchase method of accounting.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The Merger will be treated as a taxable sale of the Kevlin Common Stock.
Kevlin stockholders will be treated as if they sold their shares in a fully
taxable transaction for the cash they will receive. See "The
Acquisition -- Certain Federal Income Tax Consequences."
 
APPRAISAL RIGHTS
 
     The Massachusetts Business Corporation Law (the "MBCL") gives Kevlin's
stockholders the right to dissent from the Merger. Kevlin stockholders who
dissent from the Merger in accordance with the MBCL have the right to be paid
the "fair value" of their shares as of the date preceding the Special Meeting
(excluding any appreciation or depreciation in anticipation of the Merger). In
order to exercise these appraisal rights, a Kevlin stockholder must file a
written objection to the Merger with Kevlin prior to the taking of the vote
thereon, must not vote in favor of the Merger and must follow the other
procedures described by the MBCL. See "The Acquisition -- Kevlin Stockholder
Appraisal Rights."

                                  INTRODUCTION
 
     This Proxy Statement is being furnished to the stockholders of Kevlin in
connection with the solicitation of proxies by the Board of Directors of Kevlin
to be voted at the Special Meeting, and at any adjournment or postponement
thereof.
 
                               CORPORATE ACTIONS
 
NEWCO STOCKHOLDER CONSENT
 
     In connection with the Merger, Chelton, as the holder of all the
outstanding shares of Newco common stock, has approved the Merger Agreement by
written consent. The written consent constitutes the required corporate action
under Massachusetts law.
 
KEVLIN STOCKHOLDER MEETING
 
     The Special Meeting.  The Special Meeting will be held on January   , 1996,
at 10:00 a.m. Eastern Time, at the offices of Kevlin, 5 Cornell Place,
Wilmington, Massachusetts 01887.  The purpose of the Special Meeting is to 
obtain stockholder approval with regard to the Merger Agreement. Each Kevlin
stockholder of record at the close of business on the Record Date will be
entitled to receive notice of and to vote at the Special Meeting. At that date,
there were      shares of Kevlin Common Stock outstanding which were held of
record by approximately      holders. Each share of Kevlin Common Stock is
entitled to one vote.
 
     All proxies that are properly executed and returned, unless previously
revoked, will be voted at the Special Meeting in accordance with the
instructions thereon. With regard to any other business not specified above that
may properly come before the Special Meeting, shares represented by properly
executed proxies will be voted at the discretion of the persons named in the
relevant proxy. The execution of a proxy will not affect a stockholder's right
to attend the Special Meeting and vote in person.
 
     Required Vote.  The affirmative vote of the holders of at least two-thirds
( 2/3rds) of the outstanding Kevlin Common Stock is required to approve and
adopt the Merger Agreement. Votes withheld, abstentions and broker non-votes
(where a broker or nominee does not exercise discretionary authority to vote on
a matter) are counted for purposes of determining the presence or absence of a
quorum for the transaction of business, but, since the affirmative vote of
two-thirds of outstanding shares is required to approve the Merger Agreement,
such actions will have the effect of a negative vote. No vote of Chelton
stockholders is required, or will be sought, to consummate the transaction.
 
     THE BOARD OF DIRECTORS OF KEVLIN HAS UNANIMOUSLY RECOMMENDED A VOTE IN
FAVOR OF THE MERGER AGREEMENT. See "Summary -- Recommendation of the Board of
Directors of Kevlin," "The Acquisition -- Background of the
Acquisition," and "The Acquisition -- Kevlin's Reasons for the Acquisition."
 
     Purpose of the Meeting.  At the Special Meeting, the stockholders of Kevlin
will consider and vote upon the approval and adoption of the Merger Agreement
under which (i) the Merger and the other transactions contemplated by the Merger
Agreement are to be consummated, (ii) holders of Kevlin Common Stock are to
receive the Merger Consideration in exchange for the Kevlin Common Stock held by
each of them as of the Effective Time of the Merger, and (iii) Kevlin is to
become a wholly-owned subsidiary of Chelton. See "The Acquisition -- Merger and
Effective Time," "-- Conversion of Kevlin Common Stock" and "-- Treatment of
Options."
 
     The MBCL gives Kevlin's stockholders the right to dissent from the Merger.
Kevlin stockholders who dissent from the Merger in accordance with the MBCL have
the right to be paid the "fair value" of their shares as of the date preceding
the Kevlin Special Meeting (excluding any appreciation or depreciation in
anticipation of the Merger). In order to exercise these appraisal rights under
the MBCL, a Kevlin stockholder must file a written objection to the Merger with
Kevlin prior to the taking of the vote thereon, must not vote in
 
                                       10
<PAGE>   14
 
favor of the Merger and must follow the other procedures described by the MBCL.
See "The Acquisition -- Kevlin Stockholder Appraisal Rights."
 
     ANY KEVLIN STOCKHOLDER GIVING A PROXY HAS THE POWER TO REVOKE THE PROXY
PRIOR TO ITS EXERCISE. A PROXY MAY BE REVOKED BY (A) FILING WITH THE CLERK OF
KEVLIN, AT OR BEFORE THE TAKING OF THE VOTE AT THE KEVLIN SPECIAL MEETING, (1) A
WRITTEN NOTICE OF REVOCATION SPECIFYING THE NUMBER OF SHARES AND CLEARLY
IDENTIFYING THE PROXY TO BE REVOKED OR (2) DULY EXECUTING AND FILING A NEW PROXY
BEARING A LATER DATE, OR (B) ATTENDING THE SPECIAL MEETING AND VOTING IN PERSON
(ALTHOUGH ATTENDANCE AT THE MEETING WILL NOT IN AND OF ITSELF CONSTITUTE A
REVOCATION OF A PROXY). ANY WRITTEN NOTICE OF REVOCATION OR SUBSEQUENT PROXY
SHOULD BE SENT AND DELIVERED TO KEVLIN CORPORATION, 5 CORNELL PLACE, WILMINGTON,
MASSACHUSETTS 01887, ATTENTION: CLERK, OR HAND DELIVERED TO THE CLERK OF KEVLIN
AT OR BEFORE THE TAKING OF THE VOTE AT THE SPECIAL MEETING.
 
     Miscellaneous.  The expenses of soliciting proxies for the Special Meeting
are to be paid by Kevlin. Solicitation of proxies may be made by means of
personal calls upon, or telephonic or telegraphic communications with,
stockholders or their personal representatives by Beacon Hill Partners, Inc. who
has been retained by Kevlin to assist in such solicitation. See "Solicitation
Compensation."

                                THE ACQUISITION
 
     The detailed terms of and conditions to the consummation of the Merger are
contained in the Merger Agreement, a conformed copy of which is attached hereto
as Exhibit A and incorporated herein by reference. The following discussion sets
forth a description of the material terms and conditions of the Merger
Agreement. The description in this Proxy Statement of the terms and conditions
to the consummation of the Merger is qualified by, and made subject to, the more
complete information set forth in the Merger Agreement.
 
PRINCIPAL TERMS
 
     The Merger Agreement provides for the merger of Newco, a wholly-owned
subsidiary of Chelton, with and into Kevlin. If the Merger Agreement is approved
and adopted by the stockholders of Kevlin, certain additional conditions are
satisfied or waived and the Merger is consummated, Kevlin will be the Surviving
Corporation in the merger with Newco and will conduct the business of Kevlin as
a wholly-owned subsidiary of Chelton.
 
     As a result of the Merger, at the Effective Time the Kevlin Common Stock
then outstanding will be converted as provided in the Merger Agreement into the
right to receive the Merger Consideration, which
 
                                       11
<PAGE>   15
 
equals $4.54 per share of Kevlin Common Stock. See "The
Acquisition -- Conversion of Kevlin Common Stock."
 
     For a description of the procedures for exchanging Kevlin Common Stock for
the Merger Consideration, see "The Acquisition -- Surrender of Certificates."
 
BACKGROUND OF THE ACQUISITION
 
     Beginning in July 1995, Kevlin began the process of entertaining bids from
potential acquirors. From August through October of 1995, Kevlin received a
series of competing bids from three companies, which bids ranged from $3.80 per
share to Chelton's bid of $4.68 per share of Kevlin Common Stock. In September
1995, Kevlin entered into a letter of intent with a potential acquiror at a
price of $4.50 per share of Kevlin Common Stock. Subsequent to signing such
letter of intent, Kevlin received an offer from Chelton, and, following
discussions with Chelton, entered into a letter of intent which was signed on
October 13, 1995 by Chelton and Kevlin (the "Letter of Intent"). In the Letter
of Intent, Kevlin agreed to negotiate in good faith exclusively with Chelton for
a limited period with respect to the acquisition by Chelton of Kevlin in
exchange for $4.68 per share of Kevlin Common Stock. Chelton agreed that it
would pay Kevlin the Breakup Fee if the acquisition is not completed by Chelton,
except as a result of certain events, provided that Kevlin has adhered to the
terms of the Letter of Intent in all material respects. Further due diligence
activities and negotiations led to a reduction in the Merger Consideration to
$4.54 per share of Kevlin Common Stock, due principally to certain costs
experienced by Kevlin during the five month period ended October 31, 1995. The
parties signed the Merger Agreement on December 6, 1995.
 
KEVLIN'S REASONS FOR THE ACQUISITION
 
     The Board of Directors of Kevlin has unanimously approved the Merger
Agreement and the transactions contemplated thereby and recommends that the
stockholders of Kevlin vote in favor of the adoption of the Merger Agreement.
 
     In evaluating the transaction, the Kevlin Board of Directors was
furnished with and considered the most recent financial statements of Kevlin,
reports from management on management's plans for expansion into additional
related testing markets and reports regarding Kevlin's future financing needs.
After considering the available alternatives and the immediate and foreseeable
prospects for Kevlin, the Board of Directors of Kevlin concluded that the
Merger is in the best interests of the stockholders of Kevlin, that the Merger
offers the greatest immediate and long-term value to the stockholders and that
the Merger provides the best prospect to serve the needs of Kevlin, including
its employees and customers. Specifically, the Board of Directors concluded the
following:
 
     First, the Merger enhances stockholder value and liquidity. The Merger
Consideration is 208% higher than the average price of the Kevlin Common Stock
over the last five fiscal years and 182% higher than the price of the Kevlin
Common Stock at the end of fiscal year 1995. In addition, the Merger
Consideration is higher than any other bid received by Kevlin, and, in the
opinion of the Board of Directors, represents the highest value for the Company
that can currently be obtained.
 
     Second, the Board of Directors believes that the Merger would enable Kevlin
to expand strategically its global presence and diversify into other markets.
Kevlin's sales organization is strengthened by combining its existing network
with the world-wide organization of Chelton.
 
     Finally, the Board of Directors believes that the Merger has the potential
to improve Kevlin's operational capabilities through Kevlin's association with
Chelton and its affiliates and their management team, additional capital
resources and manufacturing facilities and capabilities. In addition, the
benefit of a larger engineering team would enable the combined company to
develop more complex systems for continued growth in markets such as air traffic
control radars, satellite communications systems and commercial positioning and
mapping systems.

MERGER AND EFFECTIVE TIME
 
     It is expected that the consummation of the transactions contemplated by
the Merger Agreement will take place on January   , 1996 (the "Closing Date").
 
     The date and time of the filing of the Articles of Merger with the
Secretary of the Commonwealth of Massachusetts, or such later time as specified
therein, shall be the Effective Time of the Merger. Kevlin and Chelton will
cause the Articles of Merger to be filed and recorded as soon as practicable on
or after the satisfaction or waiver of all conditions to the Merger. It is
expected that the Articles of Merger will be filed on the Closing Date.
 
CONVERSION OF KEVLIN COMMON STOCK
 
     As a result of the Merger, at the Effective Time each outstanding share of
Kevlin Common Stock (other than shares of holders who perfect dissenters' rights
under Massachusetts law ("Kevlin Dissenting Shares"), and shares held by any
subsidiary of Kevlin) will be converted into the right to receive $4.54 (the
"Merger Consideration").
 
TREATMENT OF OPTIONS
 
     Chelton's obligations under the Merger Agreement are conditioned upon,
among other things, all outstanding options to purchase shares of Kevlin Common
Stock being exercised or terminated at or prior to the closing of the Merger.
Pursuant to the terms of the Company's 1990 Incentive Stock Option Plan, the
Company intends to notify each optionholder that all outstanding options will be
terminated at the Effective Time. Holders of all outstanding options (including
options granted under the Company's 1980 Stock Option Plan) will be permitted,
prior to the termination of the option, to exercise such options by paying in
cash only an amount necessary to acquire a number of shares of Common Stock with
a value equal to the exercise price for an additional exercise under the option.
Thereafter, additional exercises shall be made successively by the exchange of
shares with a value equal to the exercise price of the option, with each
additional exercise resulting in the issuance of additional shares, until the
option has been exercised in full. Such "pyramiding" transactions shall occur
simultaneously and shall result in the holder of an option receiving a number of
shares with a value equal to the difference between the aggregate exercise price
of all options held by such holder and the aggregate market value of all shares
receivable upon exercise. An optionholder will be permitted to indicate that
such option exercise is to be conditioned upon, and occur immediately following,
the satisfaction of all closing conditions for the Merger, so that an option
will not be exercised if the Merger does not occur. The Closing of the Merger
will occur immediately after the exercise of such options. No stock certificates
will be issued upon the exercise of the option, but each optionholder who
exercises his options will be a holder of record in Kevlin's stock records and
entitled to receive the appropriate Merger Consideration in connection with the
Merger. Upon the consummation of the Merger and the payment of the Merger
Consideration to all Kevlin stockholders (including holders of shares of Kevlin
Common Stock issued pursuant to the exercise of options), each person who had
previously held options and exercised such options as described above will have
received an amount of cash equal to the difference between the exercise price of
the option and the Merger Consideration.
 
SURRENDER OF CERTIFICATES
 
     The Paying Agent will exchange Kevlin Common Stock certificates for an
amount of cash into which each certificate represents the right to receive. As
soon as practicable after the Effective Time, the Paying Agent will mail to all
holders of record of Kevlin Common Stock at the Effective Time instructions for
surrendering their Kevlin Common Stock certificates in exchange for cash equal
to the Merger Consideration. KEVLIN STOCKHOLDERS ARE REQUESTED NOT TO SURRENDER
THEIR CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF INSTRUCTIONS FROM
THE PAYING AGENT. Upon surrender of a Kevlin Common Stock certificate for
cancellation to the Paying Agent, the holder of such certificate shall be
entitled to receive in exchange cash in an amount equal to $4.54 for each share
previously represented by such certificate. Surrendered certificates shall
forthwith be cancelled. Until
 
                                       13
<PAGE>   17
 
surrendered, each Kevlin Common Stock certificate shall represent for all
purposes the right to receive cash equal to the Merger Consideration. Any Kevlin
Common Stock certificates surrendered for exchange more than six months after
the Effective Time must be surrendered directly to the Surviving Corporation
instead of the Paying Agent.
 
     If any Merger Consideration is to be paid to a person other than the person
in whose name the Kevlin Common Stock certificate surrendered is registered, it
shall be a condition of such exchange that the person requesting such exchange
shall deliver to the Paying Agent all documents necessary to evidence and effect
such transfer and pay to the Paying Agent any transfer or other taxes required
by reason of the payment of the Merger Consideration to a person other than that
of the registered holder of the certificate surrendered or establish to the
satisfaction of the Paying Agent that such tax has been paid or is not
applicable.
 
     At the Effective Time, the stock transfer books of Kevlin shall be closed
and no transfer of Kevlin Common Stock shall thereafter be made on those stock
transfer books.
 
INTEREST OF CERTAIN PERSONS IN THE MATTER TO BE ACTED UPON
 
     In connection with the Merger, the Board of Directors of Kevlin has
approved a payment, upon the completion of the Merger, to each of the Company's
non-employee directors (Jonathan Donaldson, Howard Mileaf and Carmine Vittoria)
of a specified percentage of the aggregate amount calculated by the application
of the so-called "Lehman Formula" to the aggregate Merger Consideration. The
aggregate Merger Consideration is expected to be $14,181,730, and the
application of the Lehman Formula to this amount yields an aggregate payment
amount of $256,033. Consequently, if the Merger is completed, Messrs. Donaldson,
Mileaf and Vittoria will receive $215,068, $30,724 and $10,241 respectively, or
84%, 12% and 4%, respectively, of the aggregate amount to be paid. This payment
was approved to compensate these directors for the successful efforts undertaken
by them in connection with the Merger and is intended to reflect the relative
contribution by each such director. Approval of such payments by Kevlin's Board
of Directors occurred prior to the Merger negotiations and, therefore, may have
created a conflict of interest for the non-employee directors in the negotiation
of the Merger Consideration and the approval of the Merger.
 
REPRESENTATIONS, WARRANTIES AND COVENANTS
 
     Kevlin, Chelton and Newco have made certain representations and warranties
to each other relating to, among other things, compliance with laws, preparation
of financial statements, legal actions and proceedings, and, in the case of
Kevlin, capitalization and share ownership, intellectual property, tax matters,
employee benefit plans, properties, and environmental matters.
 
     Kevlin has agreed that, except with the prior written consent of Chelton,
prior to the consummation of the Merger it shall observe certain covenants,
including a covenant to conduct its operations in its ordinary and usual course
of business and consistent with past practice. Kevlin has also agreed that,
except with the prior written consent of Chelton and with certain other
exceptions set forth in the Merger Agreement, it will not take certain other
actions, including (i) issue, sell or pledge, or authorize or propose the
issuance, sale or pledge of any additional securities of Kevlin, (ii) purchase
or otherwise acquire any of its outstanding securities, (iii) declare or pay any
dividend on any shares of its capital stock, (iv) propose or adopt any amendment
to its charter or by-laws, (v) enter into, assign or terminate, or amend in any

any material capital expenditures, other than pursuant to previously disclosed
capital expenditure programs, or (vii) waive, settle or compromise any material
litigation or material claim in an manner adverse to Kevlin, or incur any
indebtedness for borrowed money.
 
     Kevlin, Chelton and Newco have agreed to use their respective best efforts
to obtain all authorizations and consents of third parties necessary to the
consummation of the transactions contemplated by the Merger Agreement, to
perform and fulfill all conditions and obligations under the Merger Agreement,
to maintain, with certain exceptions, the confidentiality of information
provided by the other party in connection with the Merger, and to promptly
advise the other party prior to a party's required issuance of any press release
or other information to the press or any third party with respect to the Merger
Agreement or the transactions
 
                                       14
<PAGE>   18
 
contemplated thereby. Chelton has agreed, subject to certain conditions, to
maintain for a period of one year following the Effective Time directors' and
officers' liability insurance with respect to causes of actions that arise out
of facts or omissions occurring on or before the Effective Time.
 
     In addition, Kevlin is permitted under the Merger Agreement to pay (i) up
to $100,000, in the aggregate, to the staff of Kevlin in such proportions as
Kevlin's Board shall determine, and (ii) up to $256,033, in the aggregate, to
Kevlin's non-employee directors in full and final payment for their services to
Kevlin.
 
CONDITIONS OF MERGER
 
     In addition to the approval of the Merger Agreement by the stockholders of
Kevlin, the respective obligations of Chelton and Kevlin to consummate the
Merger are subject to the following conditions, among others: (i) the
representations and warranties contained in the Merger Agreement shall be
accurate at the Effective Time; (ii) certain covenants and agreements required
of Kevlin by the Merger Agreement to be performed or complied with shall have
been performed or complied with on or prior to the Effective Time; (iii) the

TERMINATION
 
     The Merger Agreement may be terminated prior to the Effective Time (i) by
mutual written consent of Kevlin, Chelton and Newco; (ii) by Chelton or Kevlin
if the Effective Time has not occurred on or before February 28, 1996, if the
terminating party is not in material breach under the Merger Agreement; (iii) by
Chelton or Newco if any of their conditions to closing has not been met or
waived and is no longer capable of satisfaction; (iv) by Kevlin if any of its
conditions to closing has not been met or waived and is no longer capable of

a Superior Proposal (as defined in the Merger Agreement); (b) a written opinion
of Palmer & Dodge that in furtherance of its fiduciary duties, the Board of
Directors of Kevlin is required to terminate the Merger Agreement in favor of
the Superior Proposal; (c) Kevlin's directors shall have resolved to enter into
an agreement with respect to the Superior Proposal within 48 hours after
termination of this Agreement and (d) Kevlin shall have paid $1,000,000 to
Chelton.
 
     If terminated for any reason described above, other than pursuant to
clauses (iii) or (iv) above, the Merger Agreement will become void and have no
effect, without any liability on the part of any party, its directors, officers
or stockholders with the exception of the provisions relating to confidentiality
and publicity, payment of the Termination Fee and payment of expenses, which
shall remain in effect. If either party terminates the Merger Agreement for the
reasons described in clause (iii) or (iv) above, the terminating party is
entitled to reimbursement by the other party of up to $150,000 for expenses
incurred in connection with the Merger. Termination of the Merger Agreement as
described above will not relieve any party from liability for any breach thereof
occurring before such termination.
 
WAIVER AND AMENDMENT
 
     At any time prior to the Effective Time, (i) the parties to the Merger
Agreement may, by written agreement, modify, amend or supplement any term or
provision of the Merger Agreement or extend the time for performance of any
obligation thereunder and (ii) any term or provision of the Merger Agreement may
be waived in writing by the party which is entitled to the benefits thereof;
provided, however, that after the Merger Agreement is adopted by the
stockholders of Kevlin, no such amendment or modification may be
 
                                       15
<PAGE>   19
 
made which would decrease the Merger Consideration to be received in exchange
for the Kevlin Common Stock or adversely affect the rights of such stockholders,
without the further approval of the stockholders so affected.
 
BREAKUP AND TERMINATION FEES; NO SOLICITATION
 
     Pursuant to the terms of an Escrow Agreement dated as of October 20, 1995
among Kevlin, Chelton and M&T Securities, Inc., as Escrow Agent, Chelton
deposited $1,000,000 (the "Breakup Fee") with the Escrow Agent. This amount,
plus interest earned thereon, will be paid to Kevlin if Chelton does not
complete the Merger, unless such failure to complete the Merger is due to (i) a
failure to receive approval, to the extent necessary, from the Committee on
Foreign Investment in the United States or under the Hart Scott Rodino Fair
Trade Act, (ii) the existence of unrecorded or under recorded liabilities, asset
shortfalls or future adverse events of Kevlin having, individually or in the
aggregate, a potential value of $300,000 or more, or (iii) the failure of Kevlin
to adhere to the terms of the Letter of Intent in all material respects. If the
events described in clauses (i), (ii) or (iii) of the preceding sentence occur,
the Breakup Fee will be paid to Chelton.
 
     Pursuant to the terms of the Merger Agreement, Kevlin is obligated to pay
to Chelton, upon demand, an amount of $1,000,000 (the "Termination Fee") if (i)
Kevlin, upon the advice of counsel, terminates the Merger Agreement and enters
into an agreement with a third party relating to a Superior Proposal (as defined
in the Merger Agreement) or (ii) Chelton or Newco terminate the Merger Agreement
as a result of any of the representations or warranties of Kevlin not being true
at the Effective Time or certain covenants of Kevlin not having been complied
with as of the Effective Time as a result of the intentional, deliberate or
fraudulent misrepresentation or breach of covenant by Kevlin, and such
representations, warranties and covenants are not capable of being true or
complied with on or before February 28, 1996.
 
     In the Merger Agreement, Kevlin has agreed that the Board of Directors of
Kevlin will not negotiate with another party except as required in the exercise
of its fiduciary responsibilities. Kevlin is obligated to immediately inform
Chelton of any approaches made to Kevlin by third parties.
 
EXPENSES
 
     The Merger Agreement provides that each party will bear its respective
expenses incurred in connection with the preparation, execution, and performance
of the Merger Agreement and the transactions contemplated thereby, including
without limitation, all fees and expenses of agents, representatives, counsel
and accountants.
 
REGULATORY MATTERS
 
     Pursuant to Title IV, sec. 721(a) of the Defense Production Act, as
amended, 50 U.S.C.A. Appendix sec. 2170(a), the Committee on Foreign Investment
in the United States ("CFIUS") may make an investigation to determine the
effects on national security of mergers by or with foreign persons which could
result in foreign control of persons engaged in interstate commerce in the
United States. Notice has been provided to CFIUS, and approval has been received
from the Committee to proceed with the Merger.
 
ACCOUNTING TREATMENT
 
     If the Merger is consummated, Chelton expects to account for the Merger
using the purchase method of accounting.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion summarizes the material federal income tax
consequences of the Merger to Kevlin stockholders. The discussion is based on
current provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), existing and proposed Treasury Regulations, current administrative
rulings of the Internal Revenue Service ("IRS") and judicial decisions, all of
which are subject to change. The discussion does not purport to be a complete
analysis or listing of all potential tax effects relevant to a particular Kevlin
stockholder nor does it address the tax consequences that may be relevant to
particular categories of
 
                                       16
<PAGE>   20
 
stockholders subject to special treatment under certain federal income tax laws.
In addition, it does not describe any tax consequences arising under the laws of
any state, local or foreign jurisdiction. Accordingly, each Kevlin stockholder
is urged to consult his own tax advisor regarding the tax consequences of the
Merger in his own particular tax situation and regarding state, local and
foreign tax implications of the Merger and any tax reporting requirements of the
Merger.
 
     Tax Treatment of Kevlin, Chelton and Newco.  The Merger will be treated as
a sale of the Kevlin Common Stock. Accordingly, the Company, Chelton and Newco
will recognize no gain or loss by reason of the Merger, and the basis and
holding periods of the Company's and Newco's assets immediately after the Merger
will include the basis and holding period in their hands immediately prior to
the Merger.
 
     Tax Consequences to Kevlin's Stockholders.  A stockholder who exchanges his
Kevlin Common Stock for cash in the Merger will be treated as if the shares had
been sold in a taxable transaction. Gain or loss realized will be recognized by
the stockholder with respect to the receipt of the cash in exchange for the
Company Common Stock in the Merger. The amount of gain or loss realized will be
measured by the difference between the amount of cash received and the adjusted
basis of the shares. Such gain or loss will be capital gain or loss, assuming
the shares were a capital asset in the stockholders' hands at the time of the
Merger, and will be long-term capital gain or loss if the stockholder has held
the Common Stock for more than one year at the time of the Merger.
 
     A Kevlin stockholder who exercises dissenters' rights with respect to his
shares will be subject to tax on the receipt of the payments pursuant to Section
302 of the Code (taking into account the application of the stock attribution
rules of Section 318 of the Code). In general, if the shares of Kevlin Common
Stock are held by the stockholder as a capital asset at the Effective Time such
stockholder will recognize capital gain or loss measured by the difference
between the amount of cash received by such stockholder and the basis for his
shares.
 
     THE TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY
AND IS BASED UPON PRESENT LAW. EACH KEVLIN STOCKHOLDER SHOULD CONSULT HIS OWN
TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO HIM, INCLUDING
THE APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER LAWS.
 
KEVLIN STOCKHOLDER APPRAISAL RIGHTS
 
     Pursuant to Section 85 of the MBCL any holder of record of Kevlin Common
Stock who follows the procedures specified in Sections 86 to 98 of the MBCL is
entitled to have his shares appraised by superior court in Middlesex County,
Massachusetts, and to receive the appraised value of such shares in lieu of the
Merger Consideration that such holder be otherwise entitled to receive pursuant
to the Merger Agreement. Reference is made to Sections 85 through 98 of the
MBCL, copies of which are attached to this Proxy Statement as Exhibit B, for a
complete statement of the appraisal rights of dissenting stockholders. The
following information is qualified in its entirety by reference to such
Sections.
 
     The MBCL gives stockholders of Kevlin the right to dissent from the Merger.
The MBCL sets forth the procedure whereby a stockholder who desires to dissent
from the merger action must file with Kevlin, prior to the taking of the vote of
the stockholders on the Merger, a written objection to the Merger. Voting in
person or by proxy against the Merger will not constitute the written objection
required. If the Merger is approved by the required vote, Kevlin, as the
Surviving Corporation, shall be obligated, within ten (10) days after such
approval, to notify each stockholder who has filed a written objection to the
action in compliance with Section 86 of the MBCL ("Notice of Merger"). Kevlin
stockholders who have given written notice of objection to the Merger and have
not voted in favor thereof, may, within twenty (20) days after the Notice of
Merger was mailed, make written demand on the Surviving Corporation for payment
of the fair value of such stockholders' shares. Within thirty (30) days after
the expiration of the 20 day period described above, the Surviving Corporation
shall pay to each Kevlin stockholder demanding payment the fair value of his
stock determined as of the day preceding the date of the Special Meeting
(excluding any appreciation or depreciation in
 
                                       17
<PAGE>   21
 
anticipation of the Merger). If, within such thirty (30) day period, the
Surviving Corporation and any dissenting Kevlin stockholder cannot agree upon
the fair value of such shares, the Surviving Corporation or the dissenting
stockholder may, at any time within four months after the expiration of such 30
day period, demand a determination of the value of the stock of such dissenting
stockholder by a bill in equity filed in superior court in Middlesex County. All
dissenting stockholders of Kevlin with whom the Surviving Corporation has not
reached agreement as to the value of the Kevlin Common Stock, wherever they
reside, shall be made parties to the proceeding. The fair value of Kevlin
Dissenting Shares, as determined by the court, shall be payable only upon the
surrender to the Surviving Corporation of the certificate or certificates
representing such shares, and upon payment of the fair value, the dissenting
stockholder shall cease to have any interest in such shares. Court costs shall
be borne by the party and to the extent deemed equitable by the court. Interest
shall be paid upon any award from the date of the vote approving the Merger.
Failure to timely make appropriate demand shall result in the stockholder being
bound by the terms of the Merger. Any stockholder making such demand shall not
thereafter be entitled to notice of any meeting of stockholders or to vote such
stock for any purpose and shall not be entitled to the payment of dividends or
other distribution of the stock, except in limited circumstances set forth in
Section 96 of the MBCL.
 
     In the event that stockholders elect to exercise these appraisal rights,
the receipt of cash for shares of Kevlin Common Stock will be a taxable
transaction to the Kevlin stockholders receiving such cash, as described above
under "The Acquisition -- Certain Federal Income Tax Consequences." IT IS
SUGGESTED THAT STOCKHOLDERS CONSIDERING EXERCISING STATUTORY APPRAISAL RIGHTS
CONSULT WITH THEIR OWN TAX ADVISORS WITH REGARD TO THE TAX CONSEQUENCES OF SUCH
ACTIONS.
 
     To the extent there are any inconsistencies between the foregoing summary
and Sections 85 to 98 of the MBCL, the terms of the MBCL shall control.
 
                      KEVLIN CORPORATION SUBSEQUENT EVENTS

(1) Beneficial ownership of Common Stock is determined in accordance with the
    rules of the Securities and Exchange Commission, and includes the holding of
    sole or shared voting or investment power with respect to shares of Common
    Stock. Shares of Common Stock subject to options currently exercisable or
    which become exercisable on or before December 30, 1995 are deemed to be
    beneficially owned and outstanding for purposes of computing the percentage
    of the person holding such options, but are not deemed outstanding for
    purposes of computing the percentage ownership of any other person.
 
(2) Includes the following number of shares allocated to the account of these
    executive officers and directors under the Company's Employee Stock
    Ownership Plan ("ESOP") as of August 11, 1995, as to which such person has

                           SOLICITATION COMPENSATION
 
     The cost of soliciting proxies from holders of shares of Kevlin Common
Stock will be borne by Kevlin. In addition to soliciting proxies by mail,
officers and employees of Kevlin, without receiving additional compensation
therefor, may solicit proxies by telephone, by telegram, or in person. Kevlin
has retained Beacon Hill Partners, Inc. to assist in the solicitation of
proxies. The fee to be paid to such firm is expected to be approximately $4,500
plus reimbursement for reasonable out-of-pocket costs and expenses. Kevlin will
also make arrangements with brokerage firms and other custodians, nominees, and
fiduciaries to send proxy materials to their principals.

                          AGREEMENT AND PLAN OF MERGER
 
     THIS AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of December
6, 1995, is among KEVLIN CORPORATION, a Massachusetts corporation ("Kevlin"),
Kevlin Acquisition Corp., a Massachusetts corporation and a wholly-owned
subsidiary of Chelton Communication Systems, Inc., ("NEWCO"), and CHELTON
COMMUNICATION SYSTEMS, INC., a Delaware corporation ("Chelton").
 
     The respective Boards of Directors of Chelton, NEWCO and Kevlin have duly
approved the acquisition of Kevlin by Chelton by means of a merger of NEWCO with
and into Kevlin pursuant to the terms of this Agreement. It is therefore agreed
as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     Section 1.1  The Merger.  Upon the terms and subject to the conditions
hereof, and in accordance with the relevant provisions of the Massachusetts
Business Corporation Law (the "Massachusetts Act") including, without
limitation, any required vote of shareholders of Kevlin as described in Section
2.3 of this Agreement, NEWCO shall be merged with and into Kevlin (the "Merger")
as soon as practicable following the satisfaction or waiver, if permissible, of
the conditions set forth in Article V hereof. Following the Merger, Kevlin shall
continue as the surviving corporation (the "Surviving Corporation") under the
laws of the Commonwealth of Massachusetts and the separate corporate existence
of NEWCO shall cease.
 
     Section 1.2  Effective Time.  The Merger shall be consummated by filing the
Articles of Merger with the Massachusetts Secretary of State in a form mutually
agreeable to the parties hereto (the "Articles of Merger") (the time that such
filing is accomplished is referred to herein as the "Effective Time").
 
     Section 1.3  Effects of the Merger.  The Merger shall have the effects set
forth in Section 80 of the Massachusetts Act.
 
     Section 1.4  Articles of Organization and By-Laws.  The Articles of
Organization and By-Laws of Kevlin, both as in effect at the Effective Time,
shall be the Articles of Organization and By-Laws of the Surviving Corporation.
 
     Section 1.5  Board of Directors; Officers.  As of the Effective Time, the
directors of NEWCO in office immediately prior to the Effective Time shall be
the directors of the Surviving Corporation until their respective successors are
duly elected and qualified. The officers of NEWCO immediately prior to the
Effective Time shall be the officers of the Surviving Corporation until their
successors are duly elected and qualified.
 
     Section 1.6  Conversion of Shares and Options.
 
     (a) Each share of common stock, $.10 par value per share ("Shares" or
"Kevlin Common Stock"), of Kevlin issued and outstanding immediately prior to
the Effective Time (other than Shares held by Kevlin as treasury stock, which
shall be cancelled) shall, by virtue of the Merger and without any action on the
part of any holder thereof, be converted into the right to receive a cash
payment in the amount of four dollars and fifty-four cents ($4.54) (the "Merger
Consideration"). The Merger Consideration shall be payable upon surrender of the
certificates formerly representing Shares in accordance with Section 2.2.
 
     (b) Each Share held in the treasury of Kevlin immediately prior to the
Effective Time shall, at the Effective Time, by virtue of the Merger and without
any action on the part of Kevlin, be cancelled and retired and cease to exist
and no payment shall be made with respect thereto.
 
     (c) Each share of common stock of NEWCO issued and outstanding immediately
prior to the Effective Time shall, by virtue of the Merger and without any
action on the part of Chelton, be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation.
 
                                       A-1
<PAGE>   29
 
     (d) Kevlin shall make arrangements with each holder of an option to
purchase shares of Kevlin Common Stock outstanding immediately prior to the
Effective Time ("Stock Options") to exercise such options and purchase shares of
Common Stock. Such option exercises may be accomplished by payment of the
exercise price in Common Stock, including stock acquired upon exercise of such
option, valued at the Merger Consideration, with such exercise being contingent
upon the conditions to the consummation of the Merger set forth in Article V
hereof being satisfied or waived. To the extent that a shareholder vote is not
required, all stock option plans of Kevlin shall terminate as of the Effective
Time, and Kevlin shall ensure that no holder of an option to purchase Kevlin
Common Stock shall have any rights under outstanding options or under the
relevant stock option plans except to receive the cash payment as a stockholder
entitled to payment under subsection (a) above.
 
     Section 1.7  Closing.  Upon the terms and subject to the conditions hereof,
as soon as practicable after the satisfaction of all conditions described in
Article V, Kevlin and NEWCO shall hold a closing (the "Closing") at the offices
of Palmer & Dodge in Boston, Massachusetts (or such other place as the parties
may agree), for the purpose of implementing all transactions described in this
Agreement. At the Closing, the parties shall arrange for the filing of the
Articles of Merger with the Massachusetts Secretary of State and shall take such
other and further actions as may be required by law to make the Merger
effective. The parties presently contemplate that the Closing will be held
immediately following the Special Meeting described in Section 2.3.
 
     Section 1.8  Escrow Fund.  The parties acknowledge that Chelton has
deposited $1,000,000 (the "Escrow Fund") in cash with M&T Securities, Inc. (the
"Escrow Agent") pursuant to an Escrow Agreement among Kevlin, Chelton and the
Escrow Agent. The Escrow Fund will be disbursed by the Escrow Agent as provided
for in the Escrow Agreement.
 
                                   ARTICLE II
 
                     DISSENTING SHARES; SURRENDER OF SHARES
                              AND PAYMENT THEREFOR
 
     Section 2.1  Dissenting Shares.  Section 85 of the Massachusetts Act
provides dissenter's rights in connection with the Merger to the shareholders of
Kevlin.
 
     Section 2.2  Surrender and Payment.
 
     (a) Prior to the Closing, Kevlin shall appoint an agent (the "Paying
Agent") for the purpose of paying the Merger Consideration in exchange for
certificates representing shares or options to purchase shares of Kevlin Common
Stock ("Certificates"). As soon as practicable after the Effective Time, the
Paying Agent shall send a notice and transmittal form (which shall specify that
delivery shall be effected, and risk of loss and title to Certificate(s) shall
pass, only upon delivery of such Certificate(s) to the Paying Agent and shall be
in a form and have such other provisions as Kevlin may reasonably specify) to
each Holder of a Certificate(s) theretofore evidencing shares of Kevlin Common
Stock, outstanding immediately prior to the Effective Time, advising each such
holder of the effectiveness of the Merger and the procedure for surrendering to
the Paying Agent such Certificates for payment of the Merger Consideration.
 
     (b) The Surviving Corporation shall transmit by wire or other acceptable
means to the Paying Agent prior to the Effective Time the funds necessary for
all exchanges in accordance with this Agreement. The Paying Agent shall agree to
deliver such funds (in the form of checks of the Paying Agent) in accordance
with this Section 2.2 and such additional terms as may be agreed upon by the
Paying Agent and Kevlin. Any portion of such funds which has not been paid
pursuant to this Section 2.2 by six months after the Effective Time shall
promptly be paid to the Surviving Corporation, and thereafter any stockholders
of Kevlin who have not theretofore complied with this Section 2.2 shall look
only to the Surviving Corporation for payment of the amount to which they are
entitled in the Merger.
 
     (c) Each holder of a Certificate(s) theretofore representing shares of
Kevlin Common Stock which are converted into the right to receive the Merger
Consideration, upon surrender to the Paying Agent of such
 
                                       A-2
<PAGE>   30
 
Certificate(s) for cancellation, together with a duly completed transmittal form
and such other documents as may be reasonably requested by the Paying Agent,
will be entitled promptly to receive a check representing cash in the amount of
the Merger Consideration times the number of shares of Kevlin Common Stock
represented by such Certificate(s) less any amount required to be withheld under
applicable Federal income tax regulations ("Back Withholding").
 
     (d) If payment of the Merger Consideration (or any portion thereof) is to
be made to a person other than the person in whose name the Certificate(s)
surrendered in exchange therefor is registered, it shall be a condition of such
payment that the Certificate(s) so surrendered shall be properly endorsed or
shall be otherwise in proper form for transfer and that the person requesting
such payment shall pay to the Paying Agent any transfer or other taxes required
by reason of such payment, or shall establish to the satisfaction of the Paying
Agent that such tax has been paid or is not applicable. Notwithstanding the
foregoing, neither the Paying Agent nor any party hereto shall be liable to any
person claiming the right to receive the Merger Consideration for any cash
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificate(s) shall not have been surrendered
prior to five years after the Effective Time (or immediately prior to such
earlier date on which any payment pursuant to this Article II would otherwise
escheat to or become the property of any Federal, state or local government
agency or court, administrative agency or commission or other governmental
authority or agency, domestic or foreign, the payment in respect of such
Certificate(s) 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.
 
     (e) In the event any Certificate(s) theretofore representing shares of
Kevlin Common Stock to be exchanged for the Merger Consideration has been lost,
stolen or destroyed, the Paying Agent shall pay to the person claiming that such
Certificate(s) has been lost, stolen or destroyed the cash into which the shares
theretofore represented by such Certificate(s) have been converted as provided
under the terms of this Agreement (less any required Backup Withholding), upon
receipt of evidence of ownership of such Certificate(s) and appropriate
indemnification in each case satisfactory to the Paying Agent.
 
     (f) Until surrendered as contemplated by this Section 2.2, each Certificate
shall be deemed at any time after the Effective Time to represent only the right
to receive upon such surrender the amount of cash, without interest, into which
the shares of Kevlin Common Stock theretofore represented by such Certificate
shall have been converted pursuant to Section 1.6. No interest shall accrue or
be paid on any portion of the Merger Consideration.
 
     Section 2.3  Shareholders Meeting; Preparation of Proxy Statement.
 
     (a) Kevlin will duly call, give notice of, convene and hold a special
meeting of the holders of Kevlin Common Stock (the "Special Meeting") for the
purpose of approving this Agreement as soon as practicable after the date
hereof. Subject to the requirements of applicable fiduciary duties, Kevlin will,
through its Board of Directors, recommend to its stockholders approval of this
Agreement.
 
     (b) Kevlin will prepare and file a preliminary Proxy Statement with the SEC
and will use its best efforts to respond to any comments of the SEC or its staff
and to cause the Proxy Statement to be mailed to Kevlin's stockholders as
promptly as practicable after responding to all such comments to the
satisfaction of the staff. Kevlin will notify Chelton promptly of the receipt of
any comments from the SEC or its staff and of any requests by the SEC or its
staff for amendments or supplements to the Proxy Statement or for additional
information and will supply Chelton with copies of all correspondence between
Kevlin or any of its representatives, on the one hand, and the SEC or its staff,
on the other hand, with respect to the Proxy Statement or the Merger. If at any
time prior to the Special Meeting there shall occur any event that should be set
forth in an amendment or supplement to the Proxy Statement, Kevlin will promptly
prepare and mail to its stockholders such an amendment or supplement. Kevlin
will not mail any Proxy Statement, or any amendment or supplement thereto, to
which Chelton reasonably objects.
 
     (c) Kevlin and Chelton agree that Kevlin shall engage Beacon Hill Partners
as the proxy solicitor for the Special Meeting.

                         REPRESENTATIONS AND WARRANTIES
 
     Section 3.1  Representations and Warranties of Kevlin.  Kevlin represents
and warrants to Chelton and NEWCO that:
 
     (a) Corporate Standing and Authority; Binding Agreement.  Kevlin is a
corporation duly organized, validly existing and in good standing under the laws
of the Commonwealth of Massachusetts. Kevlin has full power to own all of its
properties and assets that are owned by it and to conduct its business as it is
now being conducted, and neither its ownership or leasing of property nor the
conduct of its business requires it to be qualified as a foreign entity in any
jurisdiction in which it is not qualified where the failure to qualify would
have a Material Adverse Effect (as defined in Section 7.11(a) hereof) on
Kevlin's business. The execution of this Agreement and consummation of the
transactions contemplated herein will not violate any provision of Kevlin's
Articles of Organization or By-laws, and Kevlin has obtained all necessary
authorization and approval from its Board of Directors for the execution of this
Agreement and the consummation of the transactions contemplated hereby. This
Agreement is a legal, valid and binding agreement of Kevlin, enforceable against
it in accordance with its terms, subject to the laws of bankruptcy, insolvency
and moratorium and other laws or equitable principles generally affecting
creditors' rights and to general equitable principles. Complete and correct
copies of the Articles of Organization and By-Laws of Kevlin have been made
available to Chelton.
 
     (b) Capitalization.  The entire authorized capital stock of Kevlin consists
of 8,000,000 shares of Kevlin Common Stock and 2,000,000 Shares of Preferred
Stock. As of the date of this Agreement, 2,733,794 shares of Kevlin Common Stock

materially interfere with the conduct of its business, all of which are listed
in Exhibit 3.1(k) (collectively, the "Licenses"). Each License is valid and in

     all material respects in accordance with its terms and the requirements of
     all applicable laws, including, without limitation, ERISA, all provisions

          (4) The administrator of each Employee Benefit Plan that is an
     "employee benefit plan" as defined in section 3(3) of ERISA ("ERISA Plan")
     has complied with all applicable reporting and disclosure requirements
     under Part 1 of Title I of ERISA. Each summary plan description and summary
     of material modifications with respect to each such ERISA Plan describes
     the ERISA Plan accurately and comprehensively in accordance with the
     requirements of ERISA and each annual report/return filed with respect to
     each such ERISA Plan, including all schedules and attachments, are correct

     401(a) of the Code and any trust through which such Pension Plan is funded
     is exempt from federal income tax under section 501(a) of the Code; a
     favorable determination letter has been received from the Internal Revenue
     Service as to the qualified status of such Pension Plan and trust under the
     Internal Revenue Code as amended by the Tax Reform Act of 1986 and
     subsequent legislation. Nothing has occurred that could adversely affect
     the qualified status of such Pension Plan or trust.

     section 406 of ERISA or section 4975 of the Code) with respect to any ERISA
     Plan, other than any transaction subject to a statutory or administrative
     exemption. No person has acted or failed to act in connection with any
     Employee Benefit Plan in a manner that would subject Kevlin to direct or
     indirect liability, by indemnity or otherwise, for a breach of any
     fiduciary duty.
 
          (7) Kevlin has not incurred liability for any excise tax arising under
     section 4971, 4972, 4980, or 4980B of the Code, and no fact or event exists
     that could give rise to any such liability.
 
          (8) Kevlin has not incurred liability under Title IV of ERISA (other
     than liability for premiums to the Pension Benefit Guaranty Corporation
     ("PBGC") arising in the ordinary course), and, to its knowledge, no fact or
     event exists that could give rise to such liability. No complete or partial
     termination has occurred within the past five years with respect to any
     Pension Plan. No reportable event (within the meaning of section 4043 of
     ERISA) or event described in section 4063(a) of ERISA has occurred or is
     expected to occur with respect to any Pension Plan subject to Title IV of
     ERISA. No proceeding has been instituted by the PBGC to terminate any
     Pension Plan, nor has any notice of intent to terminate any Pension Plan
     been filed with the PBGC. All premiums due the PBGC have been paid in full
     on a timely basis.
 
          (9) No Pension Plan (subject to section 302 of ERISA or section 412 of
     the Code) has had an accumulated funding deficiency (within the meaning of
     section 302 of ERISA or section 412 of the Code), whether or not waived. No
     asset of Kevlin is the subject of a lien arising under section 302(f) of
     ERISA or section 412(n) of the Code. Kevlin has not been required to post
     security under section 307 of ERISA or section 401(a)(29) of the Code, and
     no fact or event exists that could give rise to such a lien or requirement
     to post any such security.
 
          (10) All contributions, insurance premiums, or payments required to be
     made with respect to the Employee Benefit Plans have been made by their due
     dates.
 
          (11) As to each Pension Plan that is a defined benefit plan (as
     defined in section 3(35) of ERISA) and that is subject to section 302 of
     ERISA or section 412 of the Code, the most recent actuarial valuation
     report accurately reflects the value of the plan assets and liabilities on
     an on-going basis as of the date of such valuation based on the funding
     method and actuarial assumptions specified in the report, all employee
     census data furnished to the plan's actuary by Kevlin in connection with
     such valuation and prior valuations has been accurate and complete in all
     material respects, and nothing has occurred since the date of such
     valuation that would have a materially adverse effect on the funding
     condition of the Pension Plan.
 
          (12) Except as disclosed on Exhibit 3.1(q), no Employee Benefit Plan,
     and no other commitment or agreement, provides for the payment of
     separation, severance, or similar benefits to any person solely as a result
     of any transaction contemplated by this Agreement or as a result of a
     "change in control", within
 
                                      A-10
<PAGE>   38
 
     the meaning of such term under section 280G of the Code, and the
     consummation of the transaction contemplated by this Agreement will not
     accelerate the time of payment or vesting of, or increase the amount of,
     any compensation due to any employee. Kevlin has no liability under the
     Executive Severance Agreement among Kevlin and Jeffrey Bandrowski, which is
     referenced in Exhibit 3.1(n).
 
          (13) Except as disclosed on Exhibit 3.1(q), Kevlin has no liability
     with respect to any employee or former employee for post-employment
     benefits, other than those associated with the Pension Plans, and other
     than as required by section 4980B of the Code and Part 6 of Title I of
     ERISA.
 
          (14) There has been no representation made to or communication with
     any employee that is not in accordance with the existing terms and
     limitations of the Employee Benefit Plans. Kevlin has made no commitment to
     modify any, or create any other, Employee Benefit Plan.

the Code).
 
     (s) No Multiemployer Plans.  Kevlin has never had any obligation to
contribute to any multiemployer plan within the meaning of section 3(37) or
4001(a)(3) of ERISA with respect to any of its employees. Kevlin is not and
could not become subject to any withdrawal liability within the meaning of
section 4201 of ERISA with respect to any multiemployer plan. Kevlin has never
been a substantial employer within the meaning of section 4001(a)(2) of ERISA
with respect to any single-employer plan within the meaning of section
4001(a)(15) of ERISA for which an employer could incur liability under section
4063 or 4064 of ERISA.
 
     (t) Debts and Capitalized Leases.  Exhibit 3.1(t) contains a list of all
liabilities under any capitalized lease of Kevlin. The consummation of the

obligations.

encourage, solicit or initiate the submission of any Acquisition Proposal (as
defined below), (ii) enter into any agreement with respect to any Acquisition
Proposal or (iii) participate in discussions or negotiations with, or furnish
any information to, any person in connection with any Acquisition Proposal;
provided, that, to the extent required by the fiduciary obligations of the Board
of Directors of Kevlin (as determined in good faith by the Board of Directors of
Kevlin based upon written advice of Palmer & Dodge), upon receipt of (x) an
unsolicited and written Superior Proposal (as defined in Section 5.4(c) below)
or (y) an unsolicited and written Potential Superior Proposal (as defined
below), Kevlin may: (1) take the action referred to in clause (ii) of this

Potential Superior Proposal. A "Potential Superior Proposal" shall mean a

Act) shall have been formed which beneficially owns or has the right to acquire

Kevlin shall notify Chelton promptly of any Acquisition Proposal and shall
provide Chelton with all available information with respect thereto.
 
     (c) The provisions of Section 5.4(a) shall not be deemed to prohibit the
Board of Directors of Kevlin, prior to the consummation of the Merger, from
withdrawing or modifying its approval or recommendation of the Merger or this
Agreement, if a Superior Proposal is made, provided that (i) such action is
required by the fiduciary obligations of the Board of Directors of Kevlin as
determined in good faith by a majority of the disinterested members thereof,
taking into account (x) the financial and other terms and conditions of the
 
                                      A-18
<PAGE>   46
 
Superior Proposal and (y) the time period within which the transactions

pursuant to a tender or exchange offer, a merger or otherwise on terms which a
majority of the disinterested members of the Board of Directors of Kevlin
determine in its good faith judgment to be financially superior to Kevlin's
stockholders than the Merger (based on a good faith determination that the value
of such proposal, as a whole, exceeds the value of the consideration provided
for in the Merger plus the amount of the Termination Fee, as hereinafter
defined). For purposes of this Agreement, "Third Party" shall mean any
corporation, partnership, person or other entity or "group" (as defined in
Section 13(d)(3) of the Exchange Act) other than Chelton, any affiliate of
Chelton or any of their respective directors, trustees, officers, employees,
representatives and agents or any entity controlled by one or more such persons.
 
     (d) Kevlin shall pay to Chelton upon demand an amount in cash equal to
$1,000,000 (the "Termination Fee") if: (i) Kevlin terminates this Agreement
pursuant to Section 6.1(f) or (ii) Chelton and NEWCO terminate this Agreement
pursuant to Section 6.1(c) for the reason that any of the conditions specified
in Sections 5.2(a), have not been met as a result of the intentional, deliberate
or fraudulent misrepresentation or breach of covenant by Kevlin and are not
capable of being met on or before February 28, 1996.

have been met or waived by it at such time as such condition is no longer
capable of satisfaction;

Merger, (ii) if litigation or proceedings shall be pending that are reasonably
likely to result in any of the foregoing or (iii) the condition specified in

or on behalf of the Boards of Directors of Kevlin, Chelton and NEWCO at any time
before or after adoption of this Agreement by the stockholders of Kevlin but,
after any such approval, no amendment shall be made which decreases the Merger

stockholders hereunder without the approval of such shareholders. This Agreement
may not be amended except by an instrument in writing signed on behalf of
Kevlin, Chelton and NEWCO.
 
     Section 6.4  Extension; Waiver.  At any time prior to the Effective Time,

Directors of Kevlin, Chelton and NEWCO may (a) extend the time for the
performance of any of the obligations or other acts of any other applicable
party hereto, (b) waive any inaccuracies in the representations and warranties

the agreements of any other applicable party or with any conditions to its own
obligations. Any agreement on the part of any other applicable party to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.

                                   EXHIBIT B
 
M.G.L.A. CHAPTER 156B
 
SEC. 85. DISSENTING STOCKHOLDER; RIGHT TO DEMAND PAYMENT FOR STOCK; EXCEPTION
 
     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.
 
SEC. 86. SECTIONS APPLICABLE TO APPRAISAL; PREREQUISITES
 
     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.
 
SEC. 87. STATEMENT OF RIGHTS OF OBJECTING STOCKHOLDERS IN NOTICE OF MEETING;
FORM
 
     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."
 
SEC. 88. NOTICE OF EFFECTIVENESS OF ACTION OBJECTED TO
 
     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 a 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.
 
                                       B-1
<PAGE>   51
 
SEC. 89. DEMAND FOR PAYMENT; TIME FOR PAYMENT
 
     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 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.
 
SEC. 90. DEMAND FOR DETERMINATION OF VALUE; BILL IN EQUITY; VENUE
 
     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.
 
SEC. 91. PARTIES TO SUIT TO DETERMINE VALUE; SERVICE
 
     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.
 
SEC. 92. DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION DATE
 
     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.
 
SEC. 93. REFERENCE TO SPECIAL MASTER
 
     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.

<PAGE>   52
 
SEC. 94. NOTATION ON STOCK CERTIFICATES OF PENDENCY OF BILL
 
     On motion the court may order stockholder parties to the bill to submit
their certificates of stock to the corporation for the 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.
 
SEC. 95. COSTS; INTEREST
 
     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.
 
SEC. 96. DIVIDENDS AND VOTING RIGHTS AFTER DEMAND FOR PAYMENT
 
     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 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.
 
SEC. 97. STATUS OF SHARES PAID FOR
 
     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.
 
SEC. 98. EXCLUSIVE REMEDY; EXCEPTION
 
     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.
