Preliminary Statement

         This Amendment No. 2 (this "Amendment") amends and supplements the
Statement on Schedule 13D (the "Statement") filed on October 19, 1999 by Michael
J. Collins (the "Reporting Person") with respect to the shares of Common Stock,
$.05 par value per share (the "Common Stock"), of CEM Corporation, a North
Carolina corporation (the "Issuer").

Item 3.    Source and Amount of Funds or Other Consideration.

         All shares of Common Stock currently beneficially owned by the
Reporting Person were acquired with personal funds. Information set forth in
Item 4 of this Amendment is incorporated herein by reference.

Item 4.    Purpose of Transaction.

         On December 29, 1999, the Reporting Person entered into an Agreement
and Plan of Merger (the "Merger Agreement") among the Issuer, the Reporting
Person and MJC Acquisition Corporation, a North Carolina corporation (the
"Acquisition Corporation"), a newly formed corporation owned by the Reporting
Person. The Merger Agreement provides for the merger (the "Merger") of the
Acquisition Corporation into the Issuer, and as a result, all shares of Common
Stock other than shares held by the Acquisition Corporation will be converted
into the right to receive $11.15 in cash. The Merger Agreement has been approved
by the Board of Directors of the Issuer, which has also voted to recommend that
the shareholders of the Issuer approve the Merger. The Reporting Person
contemplates that he will contribute the shares of Common Stock owned by him to
the Acquisition Corporation prior to the effective time of the Merger. A copy of
the Merger Agreement is filed as Exhibit 1 hereto and is incorporated by
reference herein.

         The Merger is subject to the approval of the holders of 66 2/3 percent
of the outstanding shares of Common Stock. The Merger Agreement requires the
Issuer to take all actions reasonably necessary to convene a meeting of its
shareholders as soon as reasonably practicable for the purpose of considering
and approving the Merger.

         The Merger Agreement provides that upon completion of the Merger, the
directors of the Acquisition Corporation and the officers of the Issuer will
become, respectively, the directors and officers of the surviving corporation of
the Merger.

         On December 28, 1999, the Reporting Person accepted on behalf of the
Acquisition Corporation a commitment letter (the "Commitment Letter") from Banc
of America Commercial Finance Corporation (the "Bank") to provide up to
$21,000,000 in debt financing and $400,000 in equity financing to fund the
Merger, including related expenses, and to provide the Issuer a working capital
line of credit following the Merger. A copy of the Commitment Letter is filed as
Exhibit 2 hereto and is incorporated by reference herein.

         On December 29, 1999, the Issuer and the Reporting Person issued a
press release (the "Press Release") announcing the signing of the Merger
Agreement. A copy of the Press Release is filed as Exhibit 3 hereto and is
incorporated by reference herein.

Item 6.    Contracts, Arrangements, Understandings or Relationships With
           Respect to Securities of the Issuer.

         The information set forth in Item 4 of this Amendment is incorporated
herein by reference.

Item 7.    Material to be Filed as Exhibits.

December 29, 1999 and is by and among CEM CORPORATION, a North Carolina
corporation ("CEM"), MJC ACQUISITION CORPORATION, a North Carolina corporation
("Acquiror"), and MICHAEL J. COLLINS, an individual residing in North Carolina
("Collins").

                                    RECITALS

         The boards of directors of CEM and Acquiror deem it advisable for the
mutual benefit of CEM and Acquiror and their respective shareholders,
respectively, that Acquiror be merged with and into CEM (the "Merger") upon the
terms and subject to the conditions set forth in the Plan of Merger (the "Plan
of Merger"), which is set forth in the Articles of Merger in substantially the
form attached hereto as EXHIBIT A (the "Articles of Merger"), and in accordance
with the North Carolina Business Corporation Act (the "North Carolina Act").

         The board of directors of Acquiror have approved and adopted this
Agreement. The board of directors and Special Committee of CEM have adopted
this Agreement and have resolved, subject to the terms of this Agreement, to
recommend to the shareholders of CEM to vote to approve this Agreement in
conjunction with their approval of the Plan of Merger.

         In consideration of the mutual covenants, agreements, representations
and warranties contained herein, and for the purpose of setting forth certain
terms and conditions of the Merger, and the mode of carrying the same into
effect, CEM, Acquiror and Collins hereby agree as follows:

                                   ARTICLE I

                            MERGER AND ORGANIZATION

         1.1   The Merger. Acquiror shall be merged with and into CEM at the
Effective Time (as defined below), upon the terms and subject to the conditions
hereinafter set forth, as permitted by and in accordance with the North

the Merger, is sometimes referred to herein as the "Surviving Corporation."
CEM, Acquiror and Collins agree that upon written notice of Acquiror to CEM
delivered at least 20 business days prior to the date of the Special Meeting,
Acquiror, CEM and Collins shall amend this Agreement to provide that the merger
contemplated hereby shall be the merger of CEM into Acquiror with Acquior being
the surviving corporation of such merger and to make other necessary changes to
so conform the Plan of Merger and Articles of Merger (as such terms are defined
herein).

         1.2   Effective Time. If this Agreement is not terminated pursuant to
ARTICLE VII hereof, as soon as practicable after all conditions to the Merger

Acquiror shall cause the Articles of Merger to be executed, acknowledged and
filed with the Secretary of State of the State of North Carolina as provided in
the North Carolina Act. The Merger shall be consummated and the closing of the
transactions contemplated by this Agreement (the "Closing") shall occur

         incorporation of the Surviving Corporation shall be amended to read as
         follows: "The name of the corporation is CEM Corporation" and Article

         common stock of the corporation shall be 100.

                  (c) The bylaws of Acquiror, as in effect immediately prior to

         Corporation, in each case until their successors are elected and
         qualified.

                  (f) If, at any time after the Effective Time, the Surviving
         Corporation shall consider or be advised that any deeds, bills of
         sale, assignments or assurances or any other acts or things are
         necessary, desirable or proper (i) to vest, perfect or confirm, of
         record or otherwise, in the Surviving Corporation its right, title or
         interest in, to or under any of the rights, properties or assets of
         CEM acquired or to be acquired as a result of the Merger, or (ii)
         otherwise to carry out the purposes of this Agreement, the Surviving
         Corporation and its proper officers and directors or their designees
         shall be authorized to execute and deliver, in the name and on behalf
         of the CEM, all such deeds, bills of sale, assignments and assurances
         and do, in the name and on behalf of CEM, all other acts and things

                                  ARTICLE II

                 CONVERSION OF SECURITIES AT THE EFFECTIVE TIME

         2.1   Conversion of Securities of CEM and Acquiror. At the Effective
Time, pursuant to this Agreement and by virtue of the Merger and without any
action on the part of CEM, Acquiror or the holders of any of the following
securities:

                  (a) Each share of common stock, par value $.05 per share, of
         CEM ("CEM Common Stock") (shares of CEM Common Stock being hereinafter
         collectively referred to as "CEM Shares" and individually as a "CEM
         Share") issued and outstanding immediately prior to the Effective Time
         (other than any CEM Shares to be cancelled pursuant to SECTION 2.1(B))
         shall be cancelled, extinguished and shall be converted automatically
         into the right to receive an amount equal to $11.15 in cash, without
         interest (the "Cash Merger Consideration"), payable to the holder
         thereof, as provided in SECTION 2.2, upon surrender of the certificate
         formerly representing the CEM Shares being converted into the right to
         receive the Cash Merger Consideration, less any required withholding
         taxes;

                  (b) Each CEM Share held in the treasury of CEM and each CEM
         Share owned by Acquiror (including CEM Shares contributed to Acquiror
         by agreement with Acquiror), if any, immediately prior to the
         Effective Time shall be cancelled without any conversion thereof and
         no payment or distribution shall be made with respect thereto; and

                  (c) Each share of Acquiror's common stock, $.01 par value
         ("Acquiror Common Stock"), that is issued and outstanding immediately
         prior to the Effective Time shall be converted into one newly issued,
         fully paid and nonassessable share of common stock of the Surviving
         Corporation.

         2.2   Payment of Cash for CEM Common Stock.

                  (a) At the Effective Time, Collins shall cause Acquiror to,
         and Acquiror shall, irrevocably deposit or cause to be deposited with
         a bank or trust company to be designated by Acquiror and reasonably
         satisfactory to CEM that is organized and doing business under the
         laws of the United States or any state thereof and has a combined
         capital and surplus of at least $100,000,000 (the "Disbursing Agent"),
         as agent for the holders of shares of CEM Common Stock, cash in the
         aggregate amount required to effect conversion of shares of CEM Common
         Stock into the Cash Merger Consideration at the Effective Time
         pursuant to SECTION 2.1(A) hereof. Pending distribution pursuant to
         SECTION 2.2(B) hereof of the cash deposited with the Disbursing Agent,
         such cash shall be held in trust for the benefit of the holders of CEM
         Common Stock and the fund shall not be used for any other purposes,
         and Acquiror and Surviving Corporation may direct the Disbursing Agent
         to invest such cash, provided that such investments (i) shall be
         obligations of or guaranteed by the United States of America,
         commercial paper obligations receiving the highest rating from either
         Moody's Investors Services, Inc. or Standard & Poor's Corporation, or
         certificates of deposit, bank repurchase agreements or bankers
         acceptances of domestic commercial banks with capital exceeding
         $250,000,000



                                       3
<PAGE>   10

         (collectively "Permitted Investments") or money market funds that are
         invested solely in Permitted Investments and (ii) shall have
         maturities that will not prevent or delay payments to be made pursuant
         to SECTION 2.2(B) hereof. Each holder of a certificate or certificates
         representing shares of CEM Common Stock cancelled at the Effective
         Time pursuant to SECTION 2.1(A) hereof may thereafter surrender such
         certificate or certificates to the Disbursing Agent, as agent for such
         holder of shares of CEM Common Stock, which shall effect the exchange
         of such certificate or certificates on such holder's behalf for a
         period ending six months after the Effective Time. Any interest and
         other income resulting from such investments shall be paid to
         Acquiror.

                  (b) After surrender to the Disbursing Agent of any
         certificate that prior to the Effective Time shall have represented
         any shares of CEM Common Stock, the Disbursing Agent shall promptly
         distribute to the individual, corporation, partnership, joint venture,
         association, joint stock company, trust, fund, unincorporated
         association, organization or other entity (each, a "Person") in whose
         name such certificate shall have been registered a check representing
         the amount of Cash Merger ------ Consideration into which such shares
         of CEM Common Stock shall have been converted at the Effective Time
         pursuant to SECTION 2.1(A) hereof. Until so surrendered and exchanged,
         each such certificate shall, after the Effective Time, be deemed to
         represent only the right to receive such Cash Merger Consideration,
         and until such surrender and exchange, none of the Cash Merger
         Consideration shall be paid to the holder of such outstanding
         certificate in respect thereof. The Surviving Corporation shall
         promptly after the Effective Time cause to be distributed to such
         holders appropriate materials to facilitate such surrender.

                  (c) If any cash deposited with the Disbursing Agent for
         purposes of payment in exchange for shares of CEM Common Stock remains
         unclaimed following the expiration of six months after the Effective
         Time, such cash shall be delivered to the Surviving Corporation by the
         Disbursing Agent, and thereafter the Disbursing Agent shall not be
         liable to any Persons claiming any amount of such cash, and the
         surrender and exchange shall be effected directly with the Surviving
         Corporation (subject to applicable abandoned property, escheat and
         similar laws). No interest shall accrue or be payable with respect to
         any amounts that any such holder shall be so entitled to receive. The
         Surviving Corporation or the Disbursing Agent shall be authorized to
         pay the cash attributable to any certificate theretofore issued that
         has been lost or destroyed, upon receipt of satisfactory evidence of
         ownership of the shares of CEM Common Stock represented thereby and of
         appropriate indemnification.

                  (d) None of Acquiror, Collins, the Surviving Corporation or
         the Disbursing Agent shall be liable to any Person in respect of any
         shares of retained CEM Common Stock (or dividends or distributions
         with respect thereto) or cash delivered to a public official pursuant
         to any applicable abandoned property, escheat or similar law. If any
         certificates representing shares of CEM Common Stock shall not have
         been surrendered prior to two years after the Effective Time (or
         immediately prior to such earlier date on which any cash, if any, in
         lieu of fractional shares of retained CEM Common Stock or any
         dividends or distributions with respect to retained CEM Common Stock
         in respect of such certificate would otherwise escheat to or become
         the property of any governmental entity), any such cash, dividends or
         distributions in respect of such certificate shall, to the



                                       4
<PAGE>   11

         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) If payment is to be made to a Person other than the
         Person in whose name a surrendered certificate, which prior to the
         Effective Time shall have represented any shares of CEM Common Stock,
         is registered, it shall be a condition to such payment that the
         certificate so surrendered shall be endorsed or shall otherwise be in
         proper form for transfer, and that the Person requesting such payment
         shall have paid any transfer and other taxes required by reason of
         such payment in a name other than that of the registered holder of the
         certificate surrendered or shall have established to the satisfaction
         of the Surviving Corporation or the Disbursing Agent that such tax
         either has been paid or is not payable.

                  (f) From and after the Effective Time, the holders of shares
         of CEM Common Stock outstanding immediately prior to the Effective
         Time shall cease to have any rights with respect to such shares of CEM
         Common Stock except as otherwise provided herein or by law.

                  (g) From and after the Effective Time, there shall be no
         transfers on the stock transfer books of the Surviving Corporation of
         any shares of CEM Common Stock that were outstanding immediately prior
         to the Effective Time. If, after the Effective Time, certificates for
         shares of CEM Common Stock are presented to the Surviving Corporation,
         they shall be cancelled and promptly exchanged for Cash Merger
         Consideration except as provided in SECTION 2.2(B) and (D).

         2.3   Exchange of Acquiror Common Stock Certificate. Immediately after
the Effective Time, upon surrender by the record holder of the certificate,
duly endorsed in blank, representing the shares of Acquiror Common Stock
outstanding immediately prior to the Effective Time, the Surviving Corporation
shall deliver to such record holder a share certificate, registered in such
holder's name, representing the number of shares of common stock of the
Surviving Corporation to which such record holder is so entitled by virtue OF
SECTION 2.1(B). Such certificate will bear a legend restricting the
transferability of such shares of the Surviving Corporation except in
accordance with applicable federal and state securities laws.

                                  ARTICLE III

              ADDITIONAL AGREEMENTS IN CONNECTION WITH THE MERGER

         3.1   Shareholders' Approval. CEM shall take all actions reasonably
necessary in accordance with applicable law and its articles of incorporation
and bylaws to convene a meeting of its shareholders as soon as reasonably
practicable for the purpose of considering and approving this Agreement and the
Merger (the "Special Meeting"). In connection with the Special Meeting, the
board of directors of CEM shall recommend that the shareholders of CEM vote to
approve this Agreement and the Merger unless the Special Committee of such
board of directors (the "Committee") has determined at any time prior to the
Special Meeting in good faith, after consultation with and based upon the
reasonably concluded advice of counsel to the



                                       5
<PAGE>   12

Committee, that making such recommendation would violate the fiduciary duties
of the board of directors under applicable law.

         3.2   Proxy Materials and Schedule 13E-3.

                  (a) In connection with the Special Meeting, CEM shall prepare
         and file a preliminary proxy statement relating to the transactions
         contemplated by this Agreement and the Merger (the "Preliminary Proxy
         Statement") with the United States Securities and Exchange Commission
         (the "SEC") and shall use its reasonable best efforts to respond to
         the comments of the SEC and to cause a definitive proxy statement to
         be mailed to CEM's shareholders (the "Definitive Proxy Statement") all
         as soon as reasonably practicable; provided, that prior to the filing
         of each of the Preliminary Proxy Statement and the Definitive Proxy
         Statement, CEM shall consult with Acquiror and Collins with respect to
         such filings and shall afford Acquiror and Collins reasonable
         opportunity to comment thereon. Acquiror and Collins shall provide CEM
         with any information for inclusion in the Preliminary Proxy Statement
         and the Definitive Proxy Statement that may be required under
         applicable law and is reasonably requested by CEM.

                  (b) CEM, Acquiror and Collins shall, and shall cause any
         other Person that may be deemed to be an affiliate of CEM to, prepare
         and file concurrently with the filing of the Preliminary Proxy
         Statement a Statement on Schedule 13E-3 ("Schedule 13E-3") with the
         SEC. If at any time prior to the Special Meeting any event should
         occur that is required by applicable law to be set forth in an
         amendment of, or supplement to, the Schedule 13E-3, CEM, Acquiror and
         Collins shall, and shall cause such Person to, file such amendments or
         supplements.

         3.3   Termination of CEM Stock Option Plans. Except as disclosed in
ITEM 3.3 of the Disclosure Schedules, as defined in SECTION 3.12 of this
Agreement, all outstanding stock options issued by CEM (collectively, the
"Stock Options"), including without limitation those issued under the CEM
Corporation 1986 Nonqualified Stock Option Plan, the 1987 Stock Option Plan,
the 1993 Management Equity Plan and the 1993 Nonqualified Stock Option Plan,
shall terminate upon the Merger. With respect to each Stock Option not
otherwise terminated by its terms upon the effectiveness of the Merger, CEM
shall obtain at the earliest practicable date and prior to the Effective Time
the written consent of each holder to the cancellation of such holders' Stock
Options (irrespective of their exercise price and whether or not then currently
exercisable) to take effect on the Effective Time or shall take appropriate
action to amend the relevant plans to provide for such cancellation. At the
Effective Time, the Surviving Corporation shall pay each holder of Stock
Options, to the extent such Stock Options have not been previously exercised or
cancelled, (x) cash in an amount equal to the product of (i) the difference
between $11.15 and the exercise price of such Stock Options (but in no event
less than $0.00), multiplied by (ii) the number of shares of CEM Common Stock
subject to such Stock Options, less (y) the amount of all applicable
withholding taxes.

         3.4   Reasonable Best Efforts; Consents; Other Filings. Upon the terms
and subject to the conditions herein provided, and subject to the duties of the
board of directors of CEM under applicable law, as it or the Committee may be
advised by counsel, each party hereto shall use its reasonable best efforts to
take, or cause to be taken, all reasonable action and to do, or cause to



                                       6
<PAGE>   13

be done and to assist and cooperate with the other parties hereto in doing, all
things necessary, proper or advisable under applicable laws and regulations and
their respective articles of incorporation and bylaws to consummate and make
effective, as soon as reasonably practicable, the transactions contemplated by
this Agreement, subject, however, to the requisite vote of shareholders of CEM.
Such actions shall include, without limitation, using reasonable best efforts
to (i) defend any lawsuits or other legal proceedings, whether judicial or
administrative and whether brought derivatively or on behalf of third parties
(including governmental agencies or officials), challenging this Agreement or
the consummation of the transactions contemplated thereby or hereby, and (ii)
effect all necessary registrations, filings and submissions of information
requested by governmental authorities. Upon the terms and subject to the
conditions hereof, and subject to the duties of the board of directors of CEM
under applicable law, as it, or the Committee, may be advised by counsel, each
of the parties hereto shall use its reasonable best efforts to take, or cause
to be taken, all reasonable actions and to do, or cause to be done, all things
necessary to satisfy the other conditions of Closing set forth herein and to
cooperate with all reasonable requests made by the other party. Without
limiting the generality of the foregoing, and notwithstanding anything in this
Agreement to the contrary, CEM shall use reasonable efforts to obtain all
consents, amendments to or waivers from other parties under the terms of all
leases and other agreements between CEM and such parties required as a result
of the transactions contemplated by this Agreement the failure of which to
obtain would have a Material Adverse Effect (as defined in SECTION 4.1) and
shall use reasonable efforts to obtain all necessary consents, approvals and
authorizations as are required to be obtained under any federal or state law or
regulation.

         3.5   Financing. Each of Acquiror and Collins shall use its reasonable
best efforts to arrange the Financing (as defined in SECTION 5.6) and to
satisfy any and all conditions set forth in the Financing Letters. Acquiror and
Collins shall keep CEM informed of the status of the Financing, including
providing written notice to CEM promptly (and in any event within two business
days) of any material adverse developments relating to the Financing. CEM shall
use its reasonable best efforts to cooperate and assist Acquiror with respect
to the Financing, the expense of which shall be borne by Acquiror, and upon
consummation of the Merger, the Surviving Corporation; provided, that CEM shall
not be obligated to obtain any extraordinary consents, waivers or approvals to
loan agreements, leases or other contracts, to agree to a material adverse
modification of the terms of such documents or to prepay or incur additional
obligations to other parties.

         3.6   Conduct of Business by CEM Pending the Merger. CEM covenants and
agrees that, prior to the Effective Time or earlier termination of this
Agreement as provided herein, unless Acquiror shall otherwise agree in writing
and except as contemplated by this Agreement:

                  (a) CEM shall, and shall cause each of its subsidiaries to,
         act and carry on its respective business in the ordinary course of
         business substantially consistent with past practice and use its
         respective reasonable best efforts to preserve substantially intact
         its current material business organizations, keep available the
         services of its current officers and employees (except for
         terminations of employees in the ordinary course of business) and
         preserve its material relationships with others having significant

         date).

         3.7   Notification of Certain Matters. Each of the parties hereto

subsequent to the date of this Agreement and prior to the Effective Time,
notify all other parties to this Agreement of: (a) any material claims,
actions, proceedings, tax audits or investigations commenced or, to its
knowledge, threatened in writing, involving or affecting such party or any of
its subsidiaries or any of their properties or assets, that if adversely
resolved could have a Material Adverse Effect on such party or could prevent,
hinder or materially delay the ability of such party to consummate the Merger
or the transactions contemplated by this Agreement, (b) any notice of, or other
communication relating to, a default or event that, with notice or lapse of
time or both, would become a default, received by such party or any of its
subsidiaries, under any agreement, lease, indenture or instrument to which such
party or any of its subsidiaries is a party or is subject where such a default
could have a Material Adverse Effect on such party, or (c) any notice or other
communication from any third party alleging that the consent of such third
party is or may be required in connection with the transactions contemplated by
this Agreement. As used in this



                                      10
<PAGE>   17

SECTION 3.7, with respect to CEM, the term "Material Adverse Effect" shall have
the meaning given to it in SECTION 4.1 and, with respect to Acquiror or
Collins, the term "Material Adverse Effect" shall mean any effect that is
materially adverse to the business, assets, prospects, operations, properties,
financial condition or results of operations of Acquiror and its subsidiaries
taken as a whole.

         3.8   Access to CEM's Books and Records. Upon reasonable notice, CEM
shall afford Acquiror and its representatives and representatives of all
prospective sources of Financing reasonable access during normal business hours
to the properties, books, records and personnel of CEM and its subsidiaries and
such additional information concerning the business and properties of CEM and
its subsidiaries as Acquiror and its representatives may reasonably request.

         3.9   Acquisition Proposals. Any offer or proposal by any Person or
group concerning any tender or exchange offer, proposal for a merger, share
exchange, recapitalization, consolidation or other business combination
involving CEM or any of its subsidiaries or divisions, or any proposal or offer
to acquire in any manner, directly or indirectly, a significant equity interest
in, or a substantial portion of the assets of, CEM or any of its subsidiaries,
other than pursuant to the transactions contemplated by this Agreement, is
hereby defined as an "Acquisition Proposal". CEM shall not, nor shall it permit
any of its officers, directors, affiliates, representatives or agents to,
directly or indirectly, (a) take any action to solicit, initiate or encourage
any Acquisition Proposal, or (b) participate in any discussions or negotiations
with or encourage any effort or attempt by any other Person or take any other
action to facilitate an Acquisition Proposal. From and after the date hereof,
CEM, its subsidiaries and all officers, directors, employees of, and all
investment bankers, attorneys and other advisors and representatives of, CEM
and its subsidiaries shall cease doing any of the foregoing. Notwithstanding
the foregoing, CEM or any such Persons may, directly or indirectly, subject to
a confidentiality agreement containing customary terms, furnish to any party
information and access in response to a request for information or access made
incident to an Acquisition Proposal made after the date hereof and may
participate in discussions and negotiate with such party concerning any written
Acquisition Proposal made after the date hereof (provided that neither CEM nor
any such Person, after the date hereof, solicited, initiated or encouraged such
Acquisition Proposal), if the Committee shall have determined in good faith
based upon the reasonably concluded advice of outside counsel that failing to
take such action would violate CEM's board of directors' fiduciary duties under
applicable law. During the term of this Agreement, the board of directors of
CEM shall notify Acquiror immediately if any Acquisition Proposal is made and
shall in such notice indicate in reasonable detail the identity of the offeror
and the terms and conditions of such Acquisition Proposal and shall keep
Acquiror promptly advised of all material developments that could culminate in
the board of directors withdrawing, modifying or amending its recommendation of
the Merger and the other transactions contemplated by this Agreement. During
the term of this Agreement, CEM shall not waive or modify any provisions
contained in any confidentiality agreement entered into relating to a possible
acquisition (whether by merger, stock purchase, asset purchase or otherwise) or
recapitalization of CEM unless the Committee shall have determined in good
faith based on reasonably concluded advice of outside counsel that failing to
take such action would violate CEM's board of directors' fiduciary duties under
applicable law.

         3.10  Director and Officer Protection. CEM shall indemnify, defend and
hold harmless, and from and after the Effective Time the Surviving Corporation
shall indemnify, defend and hold harmless the present and former directors,
officers, fiduciaries, employees and agents of CEM and its subsidiaries (each
an "Indemnified Party") against all costs and expenses (including reasonable
attorney's fees), judgments, fines, losses, claims, damages, liabilities and
settlement amounts relating to or in connection with any threatened or actual
claim, action, suit or proceeding or investigation (whether asserted before or
after the Effective Time) based in whole or in part on facts arising out of the
Indemnified Party being a director, officer, fiduciary, employee or agent of
CEM at or prior to the Effective Time (including the transactions contemplated
by this Agreement) to the fullest extent permitted under applicable law,
whether or not CEM or the Surviving Corporation is insured against any such
matter. In the event of any such threatened or actual claim, action, suit,
proceeding or investigation, (A) CEM and (after the Effective Time) the
Surviving Corporation shall pay any expenses in advance of the final
disposition of such matter to each Indemnified Party as such expenses are
incurred to the fullest extent permitted under applicable law, provided CEM or
the Surviving Party, as the case may be, receives from the Indemnified Party to
whom expenses are advanced an undertaking to repay such advances as required
under applicable law , (B) the Indemnified Parties may retain one counsel
satisfactory to them and reasonably satisfactory to CEM or the Surviving
Corporation (provided, however, that if it is inappropriate due to actual or
potential differing interests between such Indemnified Parties, each group of
Indemnified Parties may retain their own separate counsel), and CEM and the
Surviving Corporation shall pay all fees and expenses of such counsel within 30
days after statements therefor are received and (C) CEM and the Surviving
Corporation shall use their respective reasonable best efforts to assist in the
vigorous defense of any such matter. Without limiting the foregoing, in any
case in which approval by the Surviving Corporation is required to effectuate
any indemnification, the Surviving Corporation shall direct, at the election of
the Indemnified Party, that the determination of any such approval shall be
made by independent counsel mutually agreed to by the Surviving Corporation and
the Indemnified Party. The Surviving Corporation shall maintain in effect for a
period of six years after the Effective Time directors' and officers' liability
insurance with respect to matters occurring prior to the Effective Time, which
insurance shall contain terms and conditions no less advantageous than are
contained in CEM's current directors' and officers' liability insurance policy;
provided, the Surviving Corporation shall not be required to pay an annual
premium for such insurance in excess of one and one-half times the current
annual premium. This SECTION 3.10 is intended for the irrevocable benefit of
and to grant third party rights to, the Indemnified Parties and shall be
binding on all successors and assigns of Collins, Acquiror, CEM and the
Surviving Corporation. Each of the Indemnified Parties shall be entitled to
enforce the covenants contained in this SECTION 3.10. In the event the
Surviving Corporation or any of its respective successors or assigns (i)
consolidates with or merges into any other Person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger
or (ii) transfers all or substantially all of its properties and assets to any
Person, then, and in each case, the Surviving Corporation shall take such
actions so that there is a reasonable expectation that successors and assigns
of the Surviving Corporation shall assume the obligations of the Surviving
Corporation set forth in this SECTION 3.10.

         3.11  Actions of Collins Pending the Closing. Collins covenants and
agrees that, prior to the Effective Time, he will not do or fail to do or cause
any Person to do or fail to do any act that will cause CEM to breach any of its
representations and warranties set forth in Article IV hereof



                                      12
<PAGE>   19

or fail to fulfill any of its covenants and agreements hereunder; provided that
any action or failure to act by CEM shall not be attributed to or deemed to be
caused by Collins solely by reason of his service as a director, officer or
employee thereof.

                                  ARTICLE IV

                     REPRESENTATIONS AND WARRANTIES OF CEM

         CEM represents and warrants to Acquiror and Collins as follows:

         4.1   Organization and Good Standing. Each of CEM and its subsidiaries
is a duly organized and validly existing corporation in good standing under the
laws of the jurisdiction of its incorporation with all requisite power and
authority (corporate and other) to own, lease and operate its properties and
conduct its business and is duly qualified and in good standing as a foreign
corporation authorized to do business in each of the jurisdictions in which the
character of the properties owned or held under lease by it or the nature of
the business transacted by it makes such qualification necessary, except where
the failure to be so qualified would not, individually or in the aggregate,
have a Material Adverse Effect on CEM and its subsidiaries, taken as a whole.
CEM has heretofore delivered to Acquiror accurate and complete copies of its
and its subsidiaries' certificates or articles of incorporation and bylaws, as
currently in effect. For the purposes of this Agreement "Material Adverse
Change" or "Material Adverse Effect" means any change or effect that is
materially adverse to the business, assets, prospects, operations, properties,
financial condition or results of operations of CEM and its subsidiaries taken
as a whole.

         4.2   Authorization; Binding Agreement. CEM has all requisite
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby. The execution and delivery of
this Agreement and the consummation of the transactions contemplated hereby
have been duly and validly authorized by CEM's board of directors and, except
for the approval of this Agreement and the Merger by the shareholders of CEM in
accordance with the North Carolina Act and the articles of incorporation and
bylaws of CEM, no other corporate proceedings on the part of CEM are necessary
to authorize this Agreement and the transactions contemplated hereby. This
Agreement has been duly and validly executed and delivered by CEM, and subject
to the requisite approval of the shareholders of CEM, constitutes the legal,
valid and binding agreement of CEM, enforceable against CEM in accordance with
its terms, except as such enforceability may be limited by (a) bankruptcy,
insolvency, reorganization, moratorium or other laws, now or hereafter in
effect, relating to or limiting creditors' rights generally, and (b) general
principles of equity (whether considered in an action in equity or at law)
which provide, among other things, that the remedies of specific performance
and injunctive and other forms of equitable relief are subject to equitable
defenses and to the discretion of the court before which any proceedings
therefor may be brought.

         4.3   Capitalization. The authorized capital stock of CEM consists of
10,000,000 shares of CEM Common Stock and 1,000,000 shares of preferred stock,
$5.00 par value per share (the "Preferred Stock"). As of the close of business
on the business day immediately preceding the



                                      13
<PAGE>   20

date hereof, 3,043,443 shares of CEM Common Stock were outstanding and no
shares of Preferred Stock were outstanding. As of the date hereof, 432,179
shares of CEM Common Stock were reserved for issuance upon exercise of
outstanding Stock Options. All of the outstanding shares of capital stock of
CEM and the subsidiaries of CEM have been duly authorized and validly issued
and are fully paid and nonassessable. All issued and outstanding shares of
capital stock of the subsidiaries of CEM are owned by CEM or a subsidiary of
CEM free and clear of all liens, charges, encumbrances, claims and options of
any nature. Except for the Stock Options, neither CEM nor any subsidiary of CEM
has or as of the Effective Time will have granted any outstanding security,
call, option, warrant, subscription or other right, or entered into any
agreement or commitment that either (a) obligates CEM or any of its
subsidiaries to issue, sell or transfer or cause to be issued, delivered or
sold any shares of the capital stock of CEM or any subsidiary of CEM, or (b)
restricts the transfer of, or otherwise encumbers, shares of CEM Common Stock.

         4.4   Financial Statements. All consolidated financial statements of
CEM and its subsidiaries (including the notes to such financial statements)
included in CEM's Annual Report on Form 10-K for the fiscal year ended June 30,
1999 (the "Year-End Financial Statements") or in CEM's Quarterly Report on Form
10-Q for the period ending September 30, 1999 (the "Interim Financial
Statements"), in each case filed pursuant to the Securities Exchange Act of
1934, as amended (the "Exchange Act"), (a) are in accordance with the books and
records of CEM and its subsidiaries in all material respects, (b) present
fairly in all material respects the consolidated financial position, results of
operations, changes in shareholders' equity and cash flow of CEM and its
subsidiaries as of the respective dates and for the respective periods
indicated and (c) have been prepared in conformity with generally accepted
accounting principles applied in all material respects on a consistent basis
through all the periods involved, subject in the case of the Interim Financial
Statements to normal year-end adjustments and the absence of certain notes
thereto. CEM has no liabilities that are required by generally accepted
accounting principles to be disclosed on a balance sheet other than (i) those
disclosed in the Interim Financial Statements, (ii) those arising in the
ordinary course of business since September 30, 1999 or as disclosed in ITEMS
3.6(C) and (D) of the Disclosure Schedules, and (iii) liabilities that would
not, individually or in the aggregate, have a Material Adverse Effect.

         4.5   Absence of Certain Changes or Events. Since June 30, 1999, (a)
there has not been any Material Adverse Change, (b) there has not been any
damage, destruction or loss, whether covered by insurance or not, having or
that, individually or in the aggregate, could have a Material Adverse Effect,
(c) there has not been any condition, event or occurrence that, individually or
in the aggregate, has had or is reasonably likely to have a Material Adverse
Effect or is reasonably likely to give rise to a Material Adverse Change, (d)
CEM and its subsidiaries have conducted their respective businesses only in the
ordinary course consistent with past practices, (e) CEM has not changed its
accounting principles or methods in any material respect except insofar as may
be required by a change in generally accepted accounting principles, (f) there
has not been any declaration, setting aside or payment of any dividend or other
distribution (whether in cash, stock or property) with respect to the equity
interests of CEM or any of its subsidiaries, other than dividends paid by
wholly owned subsidiaries, and (g) CEM and its subsidiaries have not (i)
increased the compensation or fringe benefits of any present or former
director, officer or employee of CEM or its subsidiaries (except for increases
in salary or wages in the ordinary course of business consistent with past
practice), (ii) granted any severance or



                                      14
<PAGE>   21

termination pay to any present or former director or officer of CEM or its
subsidiaries or, other than in the ordinary course of business, to any other
employee of CEM or its subsidiaries; (iii) loaned or advanced money or other
property by CEM or its subsidiaries to any of their present or former
directors, officers or employees, or (iv) established, adopted, entered into,
amended or terminated any Company Benefit Plan (as defined in SECTION 4.14).

         4.6   SEC Reports and Other Documents. Since June 30, 1996, CEM has
filed all reports required to be filed by it with the SEC and all such reports
complied as to form in all material respects with applicable requirements of
law. Each report required to be filed by CEM with the SEC since June 30, 1996
did not on the date of filing of such reports and, except to the extent revised
or superseded by a subsequent filing with the SEC prior to the date hereof does
not, contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

         4.7   Governmental and Other Consents and Approvals. No consent,
waiver, approval, license or authorization of or designation, declaration or
filing with any governmental agency or authority or other public Persons in the
United States is required in connection with the execution or delivery by CEM
of this Agreement or the consummation by CEM of the transactions contemplated
hereby, other than (a) the approval of this Agreement and the Merger by the
shareholders of CEM, (b) filing in the State of North Carolina articles of
merger in accordance with the North Carolina Act, (c) filings required under
the Exchange Act, and (d) such other consents, waivers, approvals, licenses or
authorizations, the failure of which to be obtained will not have a Material
Adverse Effect or will not, individually or in the aggregate, materially and
adversely affect the ability of CEM to consummate the transactions contemplated
hereby.

         4.8   No Violation. Except as set forth in ITEM 4.8 of the Disclosure
Schedules, the execution and delivery of this Agreement, the filing by CEM of
articles of merger in connection with the Merger in the State of North Carolina
in accordance with the North Carolina Act, the consummation by CEM of the
transactions contemplated hereby, or compliance by CEM with any of the
provisions hereof, will not:

                  (a) violate any provision of the articles of incorporation or

         cancellation or acceleration of or "put" right with respect to any
         obligation or to loss of a benefit under, or, except as expressly
         contemplated by this Agreement, require the consent of any Person
         under, or result in the creation of any lien upon any property of CEM

         Effect.

         4.9   Litigation. There is no legal action, suit, arbitration or other

conducted by each of them, except in those instances in which failure to
possess Government Approvals, individually or in the aggregate, could not have
a Material Adverse Effect. Each of CEM and its subsidiaries has been, is and as

         Benefit Plan has at all times been maintained, by its terms and in
         operation, in accordance with the Code, ERISA, and other applicable
         laws; each Company Benefit Plan that is intended to be qualified under
         Section 401(a) of the Code, and related trust that is intended to be

         benefits attributable to service on or prior to the Closing; and other
         than the acceleration of the vesting of stock options granted under
         the Company's 1993 Management Equity Plan, no Company Benefit Plan
         provides for an increase in benefits on or after the Closing.

                  (c) Except as would not be reasonably likely, individually or
         in the aggregate, to have a Material Adverse Effect: each Company
         Benefit Plan may be amended or terminated at any time without any
         obligation or liability other than for benefits accrued prior to such
         amendment or termination, or as required to be vested pursuant to
         applicable law as a result of such amendment or termination; there are
         no actions, audits, suits, or claims that are pending or, to the
         knowledge of CEM, threatened against any Company Benefit Plan, except
         claims for benefits made in the ordinary course of the operation of
         such plans; neither CEM nor any of its subsidiaries is subject to any
         material liability, tax, or penalty whatsoever to any Person
         whomsoever as a result of CEM or any of its subsidiaries engaging in a
         prohibited transaction under ERISA or the Code; and no event has
         occurred and no condition exists that would subject CEM (either
         directly or by reason of its affiliation with any trade or business
         (whether or not incorporated) that together with the Company is
         treated as a single employer under Section 414(b), (c), (m), or (o) of
         the Code ("Company ERISA Affiliate")) to any material liability, tax,
         or penalty imposed by ERISA, the Code, or other applicable law.

                  (d) Neither CEM nor any Company ERISA Affiliate maintains,
         nor has at any time established or maintained, nor has at any time
         been obligated to make, or made, contributions to or under any plan
         subject to Title IV of ERISA.

         Environmental Law or that is reasonably expected to lead to any

         Environmental Laws, constitutes a breach of CEM's obligations under
         any contract or agreement, or is reasonably expected to give rise to
         any Environmental Claim.

For purposes of this Agreement, the following terms shall have the following
meanings:

         "Environmental Claim" means any written notice, claim, demand, action,
suit, complaint or proceeding by any Person alleging liability or potential
liability (including without limitation liability or potential liability for
investigatory costs, cleanup costs, governmental response costs, natural

out of, relating to, based on or resulting from (i) the presence, storage,
transport, discharge, emission, release or threatened release of any Hazardous

of any violation or alleged violation of any Environmental Law or Environmental
Permit or (iii) otherwise relating to obligations or liabilities under any
Environmental Laws.

any Environmental Law.

         4.16  Board Recommendation. The board of directors of CEM, at a
meeting duly called and held, has by unanimous vote of those directors present
(who constituted 100% of the directors then in office other than Collins who
recused himself from such vote because of his interest in Acquiror and in the
transactions contemplated by this Agreement) (i) determined that this Agreement
and the transactions contemplated hereby are fair to and in the best interests
of the shareholders of CEM and (ii) resolved to recommend that the holders of
the shares of CEM Common Stock approve this Agreement and the transactions
contemplated herein, including the Merger.

         4.17  Required Company Vote. The affirmative vote of at least 66 2/3%

         4.18  State Takeover Statutes. No state takeover statute or similar
statute or regulation of the State of North Carolina applies or purports to
apply to this Agreement, the Merger, or any of the other transactions
contemplated hereby. No provision of the articles of incorporation, bylaws or
other governing instruments of CEM or any of its subsidiaries would, directly
or indirectly, restrict or impair the ability of Acquiror or its affiliates to
vote, or otherwise to exercise the rights of a shareholder with respect to,
securities of CEM and its subsidiaries that may be acquired or controlled by
Acquiror or its affiliates or permit any shareholder to acquire securities of
CEM on a basis not available to Acquiror in the event that Acquiror were to
acquire securities of CEM, and neither CEM nor any of its subsidiaries has any
rights plan, preferred stock or similar arrangement that have any of the
aforementioned consequences. The board of directors of CEM has duly and validly

Agreement.

subsidiaries is, or has received any notice or has any knowledge that any other
party is, in default in any respect under any material contract, agreement,
commitment, arrangement, lease, policy or other instrument to which it or any
of its subsidiaries is a party or by which it or any such subsidiary is bound,
except for those defaults that, individually or in the aggregate, could not
have a Material Adverse Effect; and there has not occurred any event that with
the lapse of time or the giving of notice or both would constitute such a
default.

         4.20  Information in Proxy Statement. The Definitive Proxy Statement
(including any amendment thereof or supplement thereto), at the date mailed to
CEM shareholders and at the time of the Special Meeting, will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they are made, not misleading, provided,
however, that no representation is made by CEM with respect to statements made
therein based



                                      21
<PAGE>   28

respects with the provisions of the Exchange Act and the rules and regulations
thereunder.

         4.21  Properties.

                  (a) CEM and its subsidiaries hold good and valid leasehold
         title to leased real property they occupy, free of all liens except
         for liens that, individually or in the aggregate, would be reasonably
         likely to not have a Material Adverse Effect or liens securing
         indebtedness described on ITEM 3.6(D) of the Disclosure Schedules or
         reflected in the Interim Financial Statements of CEM. Except as would
         not be reasonably likely, individually or in the aggregate, to have a
         Material Adverse Effect: all real property leases are in full force
         and effect and grant in all respects the leasehold estates or rights
         of occupancy or use they purport to grant; there are no existing
         defaults (either on the part of CEM or any of its subsidiaries or any
         other party thereto) under any real property lease and no event has
         occurred that, with notice or the lapse of time, or both, would
         constitute a default (either on the part of CEM or any of its
         subsidiaries or any other party thereto) under any of the real
         property leases; and the consummation of the Merger will not result in
         the occurrence of a default under any of the real property leases
         (whether pursuant to a "change in control" provision in the real
         property leases or otherwise).

                  (b) Except with respect to liens securing indebtedness
         described on ITEM 3.6(D) of the Disclosure Schedules or reflected in
         the Interim Financial Statements of CEM, each of CEM and its
         subsidiaries have good and sufficient, valid and marketable title to
         all other real property used by it in its business, free and clear of
         all liens and other encumbrances that, individually or in the
         aggregate, would be reasonably likely to have a Material Adverse
         Effect.

the shareholders of Acquiror in accordance with the North Carolina Act and its
articles of incorporation and bylaws. No other corporate proceedings on the
part of Acquiror are necessary to authorize this Agreement, the Merger and the
transactions contemplated hereby. This Agreement has been duly and validly
executed and delivered by Acquiror and Collins and constitutes a legal, valid
and binding agreement of each of Acquiror and Collins, enforceable against
Acquiror and Collins in accordance with its terms except as such enforceability
may be limited by (a) bankruptcy, insolvency, reorganization, moratorium or
other similar laws, now or hereafter in effect, relating to or limiting
creditors, rights generally, and (b) general principles of equity (whether
considered in an action in equity or at law), which provide, among other
things, that the remedies of specific performance and injunctive and other
forms of equitable relief are subject to equitable defenses and to the
discretion of the court before which any proceedings therefor may be brought.

         5.3   No Violation. Neither the execution and delivery of this
Agreement, the filing of the Articles of Merger nor the consummation by
Acquiror and Collins of the transactions contemplated hereby, nor compliance by
Acquiror and Collins with any of the provisions hereof, will:

                  (a) violate any provision of the articles of incorporation or
         bylaws of Acquiror;

                  (b) cause Acquiror to violate in any material respect any
         statute or law or any judgment, decree, order, regulation or rule of
         any court or governmental authority applicable to Acquiror or any of
         its properties or the award of any arbitrator or panel of arbitrators;

                  (c) cause the acceleration of the maturity of any debt or
         obligation of Acquiror; or

                  (d) with or without notice or lapse of time, or both,
         violate, or be in conflict with, or constitute a default under, or
         permit the termination of, or give rise to a right of termination,
         cancellation or acceleration of or "put" right with respect to any
         obligation or to loss of a benefit under, or except as expressly
         contemplated by this Agreement, require the consent of any Person
         under, or result in the creation of any lien upon any property of
         Acquiror under, any agreement, indenture, lease, instrument, permit,
         concession, franchise, or license applicable to Acquiror or to which
         Acquiror is a party or by which Acquiror (or its properties) may be
         bound, that in the aggregate could have a material adverse effect on
         Acquiror.

         5.4   Governmental and Other Consents and Approvals. No consent,
waiver, approval, license or authorization of or designation, declaration or
filing with any governmental agency or authority or other public Persons in the
United States is required in connection with the execution or delivery by
Acquiror of this Agreement or the consummation by Acquiror of the Merger or the
transactions contemplated hereby, other than (a) filings in the State of North
Carolina in accordance with the North Carolina Act, (b) filings required under
the Exchange Act and (c) such other consents, waivers, approvals, licenses or
authorizations, the failure of which to be obtained will not have a material
adverse effect on Acquiror or on the ability of Acquiror to consummate the
transactions contemplated hereby.

         5.5   Proxy and Schedule 13E-3 Information. The information furnished
to CEM by Acquiror and/or Collins specifically for inclusion in the Definitive
Proxy Statement and the Schedule 13E-3, or any amendment or supplement thereto,
or specifically for inclusion in any other documents filed with the SEC by CEM
in connection with the Merger, shall, with respect to the Definitive Proxy
Statement at the time the Definitive Proxy Statement is mailed and at the time
of the Special Meeting, and, with respect to the Schedule 13E-3 and such other
documents, at the time of filing with the SEC and at the time of such Special
Meeting, not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

         5.6   Financing.

                  (a) Collins, on behalf of Acquiror, has accepted a commitment
         for financing necessary or appropriate to consummate the Merger in an
         amount up to $21,000,000 in debt financing and an additional $400,000
         in equity financing (the "Financing"). Such amount, plus cash of CEM
         at the Closing and additional funds to be contributed by Collins
         through Acquiror, is sufficient to fund the consummation of the
         transactions contemplated hereby, including, without limitation, (i)
         to fund the payment of the Cash Merger Consideration plus the expenses
         related to the Merger and obtaining the Financing, (ii) refinance
         CEM's outstanding indebtedness and (iii) provide for the working
         capital needs of the Surviving Corporation. Neither Collins nor
         Acquiror has any reason to believe that any condition to the Financing
         cannot or will not be waived or satisfied prior to the Effective Date.
         True and correct copies of the letters or other documents evidencing
         such commitment (the "Financing Letters") have been delivered to the
         Committee.

                  (b) Collins has sufficient personal financial resources to
         make capital contributions to Acquiror necessary to permit, with the
         cash of CEM at the Closing and the proceeds of the Financing, Acquiror
         to fund the consummation of the transactions contemplated hereby,
         including, without limitation, (i) to fund the payment of the Cash
         Merger Consideration plus the expenses related to the Merger and
         obtaining the Financing, (ii) refinance CEM's outstanding indebtedness
         and (iii) provide for the working capital needs of the Surviving
         Corporation.

         5.7   Brokers and Finders. Except for Wachovia Securities, Inc., the
fees and expenses of which shall be paid by Acquiror, neither Acquiror nor
Collins has engaged any broker, finder or investment banker which engagement
would require the payment of any brokerage, finder's or other fees by CEM in
connection with the transaction contemplated hereby.

         5.8   No Prior Activities. Acquiror has not incurred, and will not as
of the Effective Time have incurred, directly or through any subsidiary, any
liabilities or obligations, except those incurred in connection with its
organization or with the negotiation of this Agreement and the Financing.
Except in connection with this Agreement and the Merger (including without
limitation the Financing Letters), Acquiror has not engaged in any business
activities of any type or kind whatsoever, or entered into any agreements or
arrangements with any Person or become subject to or bound by any obligation or
undertaking.

         5.9   Litigation. There is no legal action, suit, arbitration or other
legal, administrative or other governmental investigation, inquiry or
proceeding (whether federal, state, local or foreign) pending or, to the
knowledge of Acquiror or Collins, threatened against or affecting Acquiror,
Collins or any of their respective properties, assets, business, franchises or
governmental approvals before any court or governmental department, commission,
board, bureau, agency, instrumentality or arbitrator, that, individually or in
the aggregate, would be reasonably likely to have a material adverse effect on
the business, assets, prospects, operations, properties, financial condition or
results of operations of Acquiror or could materially and adversely affect the
ability of Acquiror or Collins to carry out, or prevent or make unduly
burdensome, the Merger or the transactions contemplated by this Agreement.

         5.10  Surviving Corporation Not Rendered Insolvent. Assuming that CEM
complies with its covenants and agreements hereunder and there is no Material
Adverse Change affecting CEM after the date hereof and prior to the Effective
Time, immediately after the Effective Time, after giving effect to the Merger,
the Financing, and any other transactions contemplated by this Agreement to
occur at or before the Effective Time, the Surviving Corporation will not (i)
be insolvent or (ii) have unreasonably small capital with which to engage in
its business.

         5.11  No Conflicting Knowledge. Collins has reviewed the
representations and warranties of CEM set forth in Article IV hereof and to his
actual knowledge (a) such representations and warranties (to the extent
supplemented or modified by definitive Disclosure Schedules) are true and
correct in all material respects and (b) such representations and warranties
that are by their terms qualified as to materiality by the term "Material
Adverse Effect" or similar terms are true and correct.

         court or governmental body in which an unfavorable judgment or decree
         could prevent or substantially delay the consummation of the Merger,
         cause the Merger to be rescinded or, with respect to any litigation in
         connection with the Merger, result in an award of damages that could
         have a Material Adverse Effect; and

                  (c) CEM, Acquiror and Collins shall have been furnished with
         evidence satisfactory to them of the timely consent or approval of, or
         notice to, each governmental authority or other Person whose consent
         or approval, or to whom notice, is required in connection with the
         execution or delivery by CEM, Acquiror or Collins of this

<PAGE>   32

         Agreement or consummation of the transactions contemplated hereby or
         the absence of which would result in a Material Adverse Effect or
         would materially and adversely affect the ability of CEM, Acquiror or
         Collins to consummate the transactions contemplated hereby, other than
         any such consent, approval, notice required solely as a result of an
         amendment to the Agreement required by Acquiror pursuant to SECTION
         1.1 hereof.

         6.2   Conditions to Obligation of CEM to Effect the Merger. The

         Collins set forth in ARTICLE V hereof shall be true and correct in all
         material respects (except that any such representation and warranty
         that is qualified as to materiality by reference to "Material Adverse
         Effect" or any similar term shall be true and correct) as of the date
         of this Agreement and as of the Effective Time as though made on and
         as of the Effective Time, and CEM shall have received a certificate
         from Acquiror signed by its President or Chief Executive Officer and
         from Collins to that effect, provided that such signatory for Acquiror

obligations of Acquiror and Collins to effect the Merger shall be subject to
the satisfaction at or prior to the Effective Time of the following additional
conditions, unless waived by Acquiror and Collins:

                  (a) The representations and warranties of CEM set forth in
         ARTICLE IV hereof shall be true and correct in all material respects
         (except that any such representation and warranty that is qualified as

         similar term shall be true and correct) as of the date of this
         Agreement and as of the Effective Time as though all of such
         representations were made on and as of the Effective Time by CEM, and

         liability in connection therewith, and provided, further, that
         notwithstanding the foregoing Acquiror will remain obligated to effect
         the Merger despite such breach by CEM to the extent that the
         circumstances that resulted in such breach also resulted in a breach
         by Collins of his representations and warranties set forth in SECTION

                  (b) CEM shall have performed in all material respects all

<PAGE>   33

         the foregoing Acquiror will remain obligated to effect the Merger
         despite such breach by CEM to the extent that the circumstances that
         resulted in such breach also resulted in a breach by Collins of his
         representations and warranties set forth in SECTION 5.11 hereof or his
         covenant set forth in SECTION 3.11 hereof.

                                  ARTICLE VII

                 WARRANTIES AND COVENANTS; WAIVER AND AMENDMENT

         7.1   Termination. This Agreement may be terminated, and the Merger
abandoned, at any time prior to the Effective Time, by:

                  (a) mutual written consent of the boards of directors of CEM
         and Acquiror;

                  (b) Acquiror, by written notice to CEM at any time prior to
         the Effective Time, (i) in the event CEM has breached any
         representation, warranty, or covenant contained in this Agreement in
         any material respect, Acquiror has notified CEM of the breach and such
         breach cannot be or has not been cured within 15 days after the giving
         of such notice, or (ii) if the Closing shall not have occurred on or
         before May 31, 2000 and any condition precedent in SECTION 6.1 or 6.3
         hereof shall not have been met or fulfilled (unless the failure
         results primarily from Acquiror breaching any representation,
         warranty, or covenant contained in this Agreement);

                  (c) CEM, by written notice to Acquiror and Collins at any
         time prior to the Effective Time, (i) in the event Acquiror or Collins
         has breached any representation, warranty, or covenant contained in
         this Agreement in any material respect, CEM has notified Acquiror and
         Collins of the breach and such breach cannot be or has not been cured

         precedent in SECTION 6.1 or 6.2 hereof shall not have been met or
         fulfilled (unless the failure results primarily from CEM breaching any
         representation, warranty, or covenant contained in this Agreement);

                  (d) CEM, by written notice to Acquiror, if (i) the board of
         directors of CEM or the Committee has withdrawn or modified its
         approval or recommendation of this Agreement or the Merger in
         accordance with SECTION 3.1; (ii) the board of directors of CEM or the
         Committee has determined that CEM enter into a definitive agreement
         with a Person with respect to a transaction the proposal of which

         directors of CEM or the Committee, as the case may be, has first
         determined in good faith based upon the reasonably concluded advice of
         outside counsel that failing to take such action would violate CEM's
         board of directors' fiduciary duties under applicable law; or (iii)
         (A) a third party commences a tender offer or exchange offer for 25%
         or more of the outstanding shares of CEM Common Stock and that tender
         offer or exchange offer is not solicited, initiated or encouraged
         after the date hereof by CEM or any of its officers, directors,
         affiliates, representatives or agents, and (B) the board of directors

                                      27
<PAGE>   34

         their shares in such tender of exchange offer; provided that the board
         of directors of CEM or the Committee has first determined in good
         faith upon the reasonably concluded advice of outside counsel that
         failing to take such action would violate CEM's board of directors'
         fiduciary duties under applicable law; and provided further, that
         termination under this SECTION 7.1(D) shall be of no effect unless and
         until CEM pays the Fee referred to in SECTION 7.6(A) and deposits
         $800,000 with a mutually acceptable escrow agent for reimbursement to
         Acquiror of Expenses (as defined in SECTION 7.6(C));

                  (e) Acquiror, by written notice to CEM, if (i) the board of
         directors of CEM has withdrawn or modified its approval or
         recommendation of this Agreement or the Merger; (ii) CEM enters into a
         definitive agreement with a Person with respect to a transaction the
         proposal of which qualifies as an Acquisition Proposal; or (iii) (A) a
         third party commences a tender offer or exchange offer for 25% or more
         of the outstanding shares of CEM Common Stock and (B) the board of
         directors of CEM recommends that the shareholders of CEM tender their
         shares in such tender or exchange offer;

                  (f) CEM or Acquiror, by written notice to the other, if upon
         a vote at the Special Meeting, any approval of the shareholders of CEM
         necessary to consummate the Merger and the transactions contemplated
         hereby shall not have been obtained; or

                  (g) any of the parties, by written notice to the other, if
         any court of competent jurisdiction or other governmental entity shall
         have issued an order, decree or ruling or taken any other action
         permanently enjoining, restraining or otherwise prohibiting the Merger
         and such order, decree, ruling or other action shall have become final
         and nonappealable.

         Any action to be taken to terminate this Agreement under this Section
must be taken by, or pursuant to authority granted by, the boards of directors
of CEM or Acquiror, as applicable. Any such action by CEM also must be
authorized by the Committee.

         7.2   Non-Survival of Representations, Warranties and Covenants. The
respective representations and warranties of CEM, Acquiror and Collins
contained herein or in any certificate delivered pursuant hereto shall expire
with, and be terminated and extinguished upon, consummation of the Merger, and
thereafter neither Surviving Corporation, CEM, Acquiror nor any officer,
director or principal thereof nor Collins shall be under any liability
whatsoever with respect to any such representation or warranty. This SECTION
7.2 shall have no effect upon any other covenant or agreement of the parties
hereto, whether to be performed before or after the consummation of the Merger.

         7.3   Amendment. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto; provided,
however, that after approval of this Agreement by the shareholders of CEM, no
amendment may be made that reduces the amount or changes the form of
consideration to be received in the Merger or otherwise changes or effects any
change that would adversely affect the holders of CEM Common Stock without the
further approval of the shareholders of CEM in accordance with SECTION 6.1(A).

         7.4   Waiver. At any time prior to the Effective Time, whether before
or after the Special Meeting, any party hereto, by action taken by its board of
directors, may (i) extend the time for the performance of any of the
obligations or other acts of any other party hereto or (ii) subject to the
proviso contained in SECTION 7.3, waive compliance with any of the agreements
of any other party or with any conditions (other than the condition in SECTION
6.1(A)) to its own obligations. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party by a duly authorized officer, and, in
the case of CEM, authorized by the Committee.

         7.5   Effect of Termination. In the event of the termination of this
Agreement under SECTION 7.1, this Agreement shall thereafter become void and
have no effect and no party hereto shall have any liability to any other party
hereto or its shareholders or directors or officers in respect thereof, except
that (i) the provisions of SECTION 7.6 and ARTICLE VIII shall survive any such
termination if such obligations arose at or before the time of such termination
and (ii) in the event of a termination pursuant to SECTIONS 7.1 (B) or (C),
nothing contained in this SECTION 7.5 shall relieve any party from liability
for any breach of this Agreement.

         7.6   Certain Payments.

                  (a) Provided that neither Acquiror nor Collins is in material
         breach of its or his respective obligations under this Agreement, in
         the event that:

                           (1) this Agreement is terminated pursuant to SECTION
                  7.1(D) or 7.1(E); or

                           (2)     (A) an Acquisition Proposal is commenced,
                  publicly proposed, publicly disclosed or communicated to CEM
                  at any time after the date of this Agreement and such
                  Acquisition Proposal would, if consummated, be superior (as
                  compared to the Merger) to CEM's shareholders from a
                  financial point of view (a "Superior Proposal") , (B) this
                  Agreement is terminated pursuant to SECTION 7.1(B), 7.1(F) or
                  7.1(G), and (C) CEM, either on or prior to the date that is
                  nine months after such termination of this Agreement,
                  consummates with any Person a transaction the proposal of
                  which would otherwise qualify as a Superior Proposal or
                  enters into a definitive agreement with a Person with respect
                  to a transaction the proposal of which would otherwise
                  qualify as a Superior Proposal;

then in any such event, CEM shall pay Acquiror $1,000,000 (the "Fee") in
immediately available funds, plus all Expenses (as defined below) up to
$800,000 in the aggregate. Expenses shall be payable to Acquiror in immediately
available funds within three business days after receipt by CEM of reasonable
documentation therefor.

                           (b) Provided that neither Acquiror nor Collins is in
                  material breach of its obligations under this Agreement, if
                  this Agreement is terminated by Acquiror pursuant to SECTION
                  7.1(B), then CEM shall promptly reimburse Acquiror for all
                  Expenses.

                  counsel, accountants, experts and consultants to Acquiror or
                  its affiliates, and all printing and advertising expenses)

                  on their behalf in connection with this Agreement or the
                  transactions contemplated hereby (including without

                  accrued by banks, investment banking firms, other financial

                  costs and expenses incurred in connection with this Agreement
                  shall be paid by the party incurring such expenses, whether

                  upon consummation of the Merger, the Surviving Corporation
                  shall reimburse Acquiror and its Affiliates for all Expenses.

interpretation of this Agreement.

         8.6   Interpretation. As used herein, "knowledge" (or words to such
effect) of CEM shall mean actual knowledge of the officers of CEM after
reasonable inquiry.

         8.7   Subsidiaries. When a reference is made in this Agreement to

the majority of whose outstanding voting securities are directly or indirectly
owned by CEM

         8.8   Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto.

         8.9   Governing Law. This Agreement shall be governed in all respects,
including validity, interpretation and effect, by the internal laws of the
State of North Carolina, without giving effect to the principles of conflict of
laws thereof, except the laws of the state of incorporation of a party shall

         8.10  Costs and Expenses. Except as provided in SECTION 7.6 and in
this SECTION 8.10, all costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party

connection with the Special Meeting shall be borne by CEM.

         8.11  Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same agreement.

         8.12  Specific Performance. The parties hereto agree that irreparable
damage would occur in the event that any provision of this Agreement was not
performed in accordance with the terms hereof and the parties shall be entitled
to the remedy of specific performance of the terms hereof, in addition to any
other remedy at law or equity.

         8.13  Conciliation and Arbitration. If any dispute, claim or
difference arises out of or relates to this Agreement (a "Dispute"), such
Dispute shall be finally settled by arbitration in accordance with the
Commercial Arbitration Rules of the American Arbitration Association ("AAA")
effective as of the commencement of the arbitration (the "Rules"), except as
such Rules may be modified as provided herein. The arbitration shall be held in
Charlotte, North Carolina, unless the parties mutually agree to have the
arbitration held elsewhere, and judgment upon the award made therein may be
entered by any court having jurisdiction thereof. The arbitral tribunal shall
be composed of three arbitrators, each of whom shall be experienced commercial
litigators admitted to practice law in the State of North Carolina. Acquiror
and the Company shall each appoint one arbitrator. If such parties fail to
nominate an arbitrator in accordance with the preceding sentence within thirty
days from the date when the notice of intention to arbitrate referred to in
Rule 6 of the Rules has been received by the Respondent (as defined in the
Rules) such appointment shall, upon written request by either party to the AAA,
be



                                      32
<PAGE>   39

made in accordance with Rule 14 of the Rules. The two arbitrators thus
appointed shall attempt to agree upon the third arbitrator to act as
chairperson of the arbitration tribunal. If said two arbitrators fail to
appoint the chairperson within thirty days from the date of appointment of the
second arbitrator, upon written request of either party to the AAA, such
appointment shall be made in accordance with Rule 15 of the Rules. The
arbitrators shall have no power to waive, alter, amend, revoke or suspend any
of the provisions of this Agreement, provided, however, that the arbitrators
shall have the power to decide all questions with respect to the interpretation
and validity of this SECTION 8.13. The arbitration shall be conducted, and the
award shall be rendered, in the English language. An arbitrator may not act as
an advocate for the party nominating him, and all three arbitrators shall be
impartial and unbiased. A majority vote by the three arbitrators shall be
required on any decision made by them. The arbitrators shall permit such
discovery as they shall determine is appropriate in the circumstances, taking
into account the needs of the parties and the desirability of making discovery
expeditious and cost-effective. Any such discovery shall be limited to
information directly relevant to the controversy or claim in arbitration and
shall be concluded within thirty days after the appointment of the arbitration
panel. This agreement to arbitrate shall be binding upon the heirs, successors
and assigns and any trustee, receiver or executor of any party hereto. Except
to the extent required by law or court or administrative order, no party,
arbitrator, representative, counsel or witness shall disclose or confirm to any
Person not present at the arbitration hearings any information about the
arbitration proceeding or hearings, including the names of the parties and
arbitrators, the nature and amount of the claims, the financial condition of
any party, the expected date of hearing or the award made.

         shall be cancelled, extinguished and shall be converted automatically

         formerly representing the CEM Shares being converted into the right to
         receive the Cash Merger Consideration, less any required withholding
         taxes;

                  (b) Each CEM Share held in the treasury of CEM and each CEM
         Share owned by Acquiror (including CEM Shares contributed to Acquiror
         by agreement with Acquiror), if any, immediately prior to the
         Effective Time shall be cancelled without any conversion thereof and

                  (c) Each share of Acquiror's common stock, $.01 par value
         ("Acquiror Common Stock"), that is issued and outstanding immediately
         prior to the Effective Time shall be converted into one newly issued,
         fully paid and nonassessable share of common stock of the Surviving
         Corporation.


         Section 2.2     Payment of Cash for CEM Common Stock.

                  (a) At the Effective Time, Acquiror shall irrevocably deposit

         doing business under the laws of the United States or any state
         thereof and has a combined capital and surplus of at least
         $100,000,000 (the "Disbursing Agent"), as agent for the holders of
         shares of CEM Common Stock, cash in the aggregate amount required to
         effect conversion of shares of CEM Common Stock into the Cash Merger

         deposited with the Disbursing Agent, such cash shall be held in trust
         for the benefit of the holders of CEM Common Stock and the fund shall
         not be used for any other purposes, and Acquiror and Surviving
         Corporation may direct the Disbursing Agent to invest such cash,

         obligations receiving the highest
<PAGE>   44

         or money market funds that are invested solely in Permitted
         Investments and (ii) shall have maturities that will not prevent or
         delay payments to be made pursuant to SECTION 2.2(B) hereof. Each
         holder of a certificate or certificates representing shares of CEM
         Common Stock cancelled at the Effective Time pursuant to SECTION
         2.1(A) hereof may thereafter surrender such certificate or
         certificates to the Disbursing Agent, as agent for such holder of
         shares of CEM Common Stock, which shall effect the exchange of such
         certificate or certificates on such holder's behalf for a period
         ending six months after the Effective Time. Any interest and other
         income resulting from such investments shall be paid to Acquiror.

                  (b)    After surrender to the Disbursing Agent of any
         certificate that prior to the Effective Time shall have represented
         any shares of CEM Common Stock, the Disbursing Agent shall promptly
         distribute to the individual, corporation, partnership, joint venture,
         association, joint stock company, trust, fund, unincorporated
         association, organization or other entity (each, a "Person") in whose
         name such certificate shall have been registered a check representing
         the amount of Cash Merger Consideration into which such shares of CEM
         Common Stock shall have been converted at the Effective Time pursuant
         to 2.1(A) hereof. Until so surrendered and exchanged, each such
         certificate shall, after the Effective Time, be deemed to represent
         only the right to receive such Cash Merger Consideration, and until
         such surrender and exchange, none of the Cash Merger Consideration
         shall be paid to the holder of such outstanding certificate in respect
         thereof. The Surviving Corporation shall promptly after the Effective
         Time cause to be distributed to such holders appropriate materials to
         facilitate such surrender.

                  (c)    If any cash deposited with the Disbursing Agent for
         purposes of payment in exchange for shares of CEM Common Stock remains
         unclaimed following the expiration of six months after the Effective
         Time, such cash shall be delivered to the Surviving Corporation by the
         Disbursing Agent, and thereafter the Disbursing Agent shall not be
         liable to any Persons claiming any amount of such cash, and the
         surrender and exchange shall be effected directly with the Surviving
         Corporation (subject to applicable abandoned property, escheat and
         similar laws). No interest shall accrue or be payable with respect to
         any amounts that any such holder shall be so entitled to receive. The
         Surviving Corporation or the Disbursing Agent shall be authorized to
         pay the cash attributable to any certificate theretofore issued that
         has been lost or destroyed, upon receipt of satisfactory evidence of
         ownership of the shares of CEM Common Stock represented thereby and of
         appropriate indemnification.

                  (d)    None of Acquiror, the Surviving Corporation or the
         Disbursing Agent shall be liable to any Person in respect of any
         shares of retained CEM Common Stock (or dividends or distributions
         with respect thereto) or cash delivered to a public official pursuant
         to any applicable abandoned property, escheat or similar law. If any
         certificates representing shares of CEM Common Stock shall not have
         been surrendered prior to two years after the Effective Time (or
         immediately prior to such earlier date on which any

         cash, if any, in lieu of fractional shares of retained CEM Common
         Stock or any dividends or distributions with respect to retained CEM
         Common Stock in respect of such certificate would otherwise escheat to
         or become the property of any governmental entity), any such cash,
         dividends or distributions in respect of such certificate shall, to
         the extent permitted by applicable law, become the property of the
         Surviving Corporation, free and clear of all claims or interest of any
         Person previously entitled thereto.

                  (e)    If payment is to be made to a Person other than the
         Person in whose name a surrendered certificate, which prior to the
         Effective Time shall have represented any shares of CEM Common Stock,
         is registered, it shall be a condition to such payment that the
         certificate so surrendered shall be endorsed or shall otherwise be in
         proper form for transfer, and that the Person requesting such payment
         shall have paid any transfer and other taxes required by reason of
         such payment in a name other than that of the registered holder of the
         certificate surrendered or shall have established to the satisfaction
         of the Surviving Corporation or the Disbursing Agent that such tax
         either has been paid or is not payable.

                  (f)    From and after the Effective Time, the holders of
         shares of CEM Common Stock outstanding immediately prior to the
         Effective Time shall cease to have any rights with respect to such
         shares of CEM Common Stock except as otherwise provided herein or by
         law.

                  (g)    From and after the Effective Time, there shall be no
         transfers on the stock transfer books of the Surviving Corporation of
         any shares of CEM Common Stock that were outstanding immediately prior
         to the Effective Time. If, after the Effective Time, certificates for
         shares of CEM Common Stock are presented to the Surviving Corporation,
         they shall be cancelled and promptly exchanged for Cash Merger
         Consideration except as provided in SECTION 2.2(B) and 2.2(D); and

         Section 2.3     Exchange of Acquiror Common Stock Certificate.

                  Immediately after the Effective Time, upon surrender by the
record holder of the certificate, duly endorsed in blank, representing the
shares of Acquiror Common Stock outstanding immediately prior to the Effective
Time, the Surviving Corporation shall deliver to such record holder a share
certificate, registered in such holder's name, representing the number of
shares of common stock of the Surviving Corporation to which such record holder
is so entitled by virtue of SECTION 2.1(C).

          II.  These Articles of Merger shall become effective immediately upon
filing with the North Carolina Secretary of State.

                              BACF as a result of fraud, waste, misapplication of funds (including,
                              nonpayment of taxes or insurance premiums resulting therefrom and failure to
                              account properly for any security deposit or other deposit), and any direct or
                              indirect transfer of any collateral or the existence of liens on the
                              collateral in violation of the Loan Documents (collectively, the "Recourse
                              Obligations"). In addition, the Financing shall become recourse to Dr. Collins
                              in the event of the voluntary bankruptcy of Holdings or the Company, or any
                              involuntary bankruptcy filed

                            Bankruptcy Obligations shall be evidenced by a Limited Guaranty and Indemnity

                            damage, loss or expense arising out of, or in connection with, or any action

                                                                       EXHIBIT 3

                        CEM AGREES TO BE ACQUIRED BY CEO


         CHARLOTTE, NC (BUSINESS WIRE), December 29, 1999 - CEM Corporation
(NASDAQ/NM:CEMX) and Michael J. Collins, its President and Chief Executive
Officer, announced today that they had entered into a merger agreement pursuant
to which Mr. Collins would acquire all of the Company's outstanding shares not
owned by him at a price of $11.15 per share in cash. This price represents a 94%
premium to the closing price of CEM common stock on October 18, 1999, the day
the Company announced Mr. Collins' first acquisition proposal, and a 32% premium
to the CEM's closing stock price of $8.4375 on December 29, 1999. The $11.15
price is also 33% greater than the $8.40 per share price initially proposed by
Mr. Collins in October.

         A Special Committee of the Board of Directors of CEM, which was
appointed to consider the transaction and assess other strategic alternatives,
has received the opinion of Brookwood Associates, Inc., its financial advisor,
that, subject to the assumptions and limitations set forth in its opinion, the
$11.15 per share cash consideration to be received by the shareholders of CEM
pursuant to the merger is fair from a financial point of view to such
shareholders.

         The transaction is subject to approval by CEM's shareholders and to
certain other customary conditions. The Company currently believes that the
shareholder vote and the closing of the transaction (if approved by the
shareholders) could occur early in the Company's fourth fiscal quarter (the
second calendar quarter).

         The transaction is not subject to any financing contingency. Mr.
Collins has accepted a commitment from Banc of America Commercial Finance
Corporation to provide the necessary financing, which commitment was arranged
for Mr. Collins by his financial advisor, Wachovia Securities, Inc.

         Ronald A. Norelli, Chairman of CEM's Board of Directors and a member of
the Special Committee, stated that "with the help of Brookwood Associates, we
looked at a number of alternatives in considering Mike's transaction. His offer
was the best alternative, and it's clearly in the best interests of the
shareholders." Mr. Collins added that "I am pleased my offer was accepted by the
Board and will be recommended to the shareholders. I believe this is a win-win
situation for the shareholders and the Company. It will create substantial
shareholder value with a sizeable premium."

         "Given CEM's size and today's dynamics in the public arena, it is
appropriate for CEM to once again be a private company. I continue to be excited
about the opportunities for CEM as a private company with our new financial
partner Bank of America. I look forward to the challenges ahead and am confident
CEM will remain a leading company in our industry," Collins continued.

         The affirmative vote of holders of 66 2/3% of CEM's outstanding common
stock is needed to approve the transaction. Mr. Collins beneficially owns in
excess of 15% of the outstanding common stock of CEM.

         CEM manufactures microwave-based instrumentation for testing and
analysis. The Company's products are used worldwide in the general analytical
laboratory market, and in many manufacturing industries, including food and
chemical processing.
