to other facts or circumstances, and each such right shall be deemed an ongoing
right that may be asserted at any time and from time to time. Any determination
(which will be made in good faith after consultation with the Company) by Buyer
with respect to any of the foregoing conditions (including, without limitation,
the satisfaction of such conditions) shall be final and binding on all parties.

        Buyer may provide a "subsequent offering period" (as contemplated by
Rule 14d-11 of the Exchange Act) of not less than three Business Days following
its acceptance of and payment for the Shares in the Offer. Subject to the terms
and conditions of the Offer and this Agreement, Buyer shall (and Parent shall
cause Buyer to) accept for payment, and pay for, all Shares validly tendered and
not withdrawn pursuant to the Offer that Buyer becomes obligated to accept for
payment and pay for pursuant to the Offer, as promptly as practicable after the
expiration of the Offer.

        (b) As soon as practicable on the date of commencement of the Offer,
Parent and Buyer shall file or cause to be filed with the SEC a Tender Offer

and including the exhibits thereto, the "SCHEDULE TO"). The Schedule TO shall
contain or shall incorporate by reference the offer to purchase, related letter
of transmittal, summary advertisement and other ancillary offer documents and
instruments pursuant to which the Offer will be made (such Schedule TO and the
documents included therein pursuant to which the Offer will be made, together
with any supplements or amendments thereto, the "OFFER DOCUMENTS") with respect
to the Offer. Parent and Buyer will take all steps necessary to cause the Offer
Documents to be filed with the SEC and to be disseminated to holders of the
Shares, in each case as and to the extent required by applicable federal
securities laws. Parent and Buyer agree that the Offer Documents shall

comply as to form in all material respects with the Exchange Act and the rules
and regulations promulgated thereunder. The Offer Documents, on the date first
published, sent or given to the Company Shareholders, shall 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 were made, not misleading, except
that no representation or warranty is made by Parent or Buyer with respect to
information supplied by the Company or any of its shareholders specifically for
inclusion or incorporation by reference in the Offer Documents and not
subsequently corrected prior to filing. Each of Parent, Buyer and the Company
agrees promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that such information shall have become false or
misleading in any material respect. Parent and Buyer each further agrees to take
all steps necessary to cause the Schedule TO as so corrected to be filed with
the SEC and the other Offer Documents as so corrected to be disseminated to the
Company Shareholders, in each case as and to the extent required by applicable
Law. The Company and its counsel shall be given an opportunity to review and

Shareholders pursuant to the Offer and the Merger is fair to the Company
Shareholders from a financial point of view. The Company further represents and
warrants that it has been authorized by the Financial Advisor to permit, subject
to prior review and consent by the Financial Advisor (such consent not to be

such fairness opinion (or a reference thereto) in the Offer Documents and in the
Schedule 14D-9 referred to below. The Company hereby consents to the inclusion

        (b) The Company shall file with the SEC concurrently with the
commencement of the Offer or as promptly thereafter as practicable a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with all

form in all material respects with the requirements of the Exchange Act and the
rules and regulations promulgated thereunder. The Company shall cause the
Schedule 14D-9 to be mailed to the Company Shareholders promptly after

Company with respect to information supplied by Parent or Buyer specifically for
inclusion in the Schedule 14D-9. Each of the Company, Parent and Buyer agrees
promptly to correct any information provided by it for use in the Schedule 14D-9
if and to the extent that such information shall have become false or misleading
in any material respect, and the Company further agrees to take all steps
necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule
14D-9 as so amended or supplemented to be filed with the SEC and disseminated to
the Company Shareholders, in each case as and to the extent required by
applicable Law. Parent, Buyer and their counsel shall be given an opportunity to

thereon as soon as practicable to counsel for the Company) prior to its filing
with the SEC or dissemination to Company Shareholders. The Company agrees to
provide Parent, Buyer and their counsel any comments the Company or its counsel
may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after the receipt of such comments.

        (c) In connection with the Offer and the Merger, the Company shall
promptly furnish or cause its transfer agent to promptly furnish Buyer with

stockholders, security position listings and computer files and all other
information in the Company's possession or control regarding the beneficial
owners of Shares, and shall furnish to Parent such information and assistance
(including updated lists of stockholders, security position listings and
computer files) as Parent may reasonably request in communicating the Offer and
the Merger to the Company Shareholders. Subject to the requirements of
applicable Law, and except for such steps as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Merger,
Parent, Buyer and their agents shall hold in confidence the information
contained in any such labels, listings and files, and will use such information
only in connection with the Offer and the Merger. In connection with the Offer,
the Company will furnish Parent with such information (which will be treated and
held in confidence by Parent) and assistance as Parent or its officers,
employees, accountants, counsel and other representatives may reasonably request
in connection with the preparation of the Offer and communicating the Offer to
the record and beneficial holders of shares of Common Stock. If this Agreement
is terminated, Parent and Buyer will upon the written request of the Company
promptly deliver or cause to be delivered to the Company all copies of any such

        2.3 BOARD OF DIRECTORS.

        (a) Effective upon the purchase by Buyer pursuant to the Offer of such
number of Shares which represents at least 67% of the outstanding shares of
Common Stock on a fully diluted basis (as defined in Annex A), and from time to
time thereafter, Parent shall be entitled to designate up to that number of
directors of the Company, rounded up to the next whole number as will make the
percentage of the Company's directors designated by Parent equal to the
percentage of outstanding shares of Common Stock held by Parent and any of its
wholly owned Subsidiaries (including Buyer), including shares of Company Common
Stock accepted for payment pursuant to the Offer. The Company shall take all
action necessary to cause the designees of Parent to be elected to or appointed
by the Company Board, including, without limitation, increasing the number of
directors, amending its bylaws, or using its best efforts to obtain resignations
of incumbent directors, subject in all cases to Section 14 (f) of the Exchange
Act. Upon written request by Parent, the Company shall use its best efforts to
cause the designees of Parent to constitute the same percentage of
representation as is on the Company Board after giving effect to this SECTION
2.3 on (i) each committee of the Company Board; (ii) the Board of Directors of
each of the Acquired Entities; and (iii) each committee of each such board. The
provisions of this SECTION 2.3 are in addition to and shall not limit any rights
that Parent, or any of its affiliates may have as a holder or beneficial owner
of Shares as a matter of law with respect to the election of directors or
otherwise.

        (b) The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under SECTION 2.3(A), including mailing to
shareholders the information required by such Section 14(f) and Rule 14f-1 as is
necessary to enable Parent's designees to be elected or appointed to the
Company's Board (the "14F-1 INFORMATION STATEMENT"). Parent shall supply the
Company and be solely responsible for any information with respect to it and its
nominees, officers, directors and affiliates required by such Section 14(f) and
Rule 14f-1. The 14f-1 Information Statement, on the date filed with the SEC and
on the date first published, sent or given to the Company Shareholders, shall
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 were made,
not misleading, except that no representation or warranty is made by the Company
with respect to information supplied by Parent specifically for inclusion in the
14f-1 Information Statement.

        (c) Following the election or appointment of Parent's designees to the
Company Board, and prior to the Effective Time (as defined in SECTION 3.1(B)),
the Company Board shall have at least two directors who are directors on the
date hereof and who are not officers of the Company or affiliates of Parent or
Buyer (the "INDEPENDENT DIRECTORS"), provided that, in such event, if the number
of Independent Directors shall be reduced below two for any reason whatsoever,
any remaining Independent Directors (or Independent Director, if there be only
one remaining) shall be entitled to designate persons to fill such vacancies who
shall be deemed to be Independent Directors for purposes of this Agreement or,
if no Independent Director then remains, the other directors shall designate two
persons to fill such vacancies who shall not be affiliates of Parent or Buyer or
officers of the Company and such persons shall be deemed to be Independent
Directors for purposes of this Agreement. Notwithstanding anything in this
Agreement to the contrary, following the election or appointment of Parent's
designees to the

                                    Page 14
<PAGE>

Company Board, and prior to the Effective Time, the affirmative vote of a
majority of the Independent Directors shall be required to (a) amend or
terminate this Agreement by the Company or (b) exercise or waive any of the
Company's rights, benefits or remedies hereunder.

                                   ARTICLE 3.
                                   THE MERGER

        3.1 THE MERGER.

        (a) Subject to the terms and conditions hereof, and in accordance with
the DGCL and the TBCA, Buyer shall be merged with and into the Company at the
Effective Time (the "MERGER"). Upon consummation of the Merger, the separate
existence of Buyer shall cease and the Company shall be the surviving
corporation (the "SURVIVING CORPORATION") and an indirect wholly-owned
subsidiary of Parent.

        (b) As soon as practicable after satisfaction of (or, to the extent
permitted hereunder, waiver of) all conditions to the Merger, the Company and
Buyer will file a certificate of merger with the Secretary of State of the State
of Delaware and deliver articles of merger to the Secretary of State of the
State of Texas in accordance with the DGCL and TBCA (in the forms attached
hereto as EXHIBIT B) and make all other filings or recordings required by
applicable Law in connection with the Merger. The Merger shall become effective
at such time as the certificate of merger is filed with the Secretary of State
of the State of Delaware and a certificate of merger is issued to the Surviving
Corporation by the Secretary of State of the State of Texas or at such later
time as is specified in the respective certificates of merger (the "EFFECTIVE
TIME"). The certificates and articles of merger filed with the Secretary of
States of of the States of Delaware and Texas are referred to throughout the
remainder of this Agreement as the "CERTIFICATES OF MERGER."

        (c) At the Effective Time, the effect of the Merger shall be as provided
in the applicable provisions of Delaware Law. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time, all the property,
rights, privileges, powers and franchises of the Company and Buyer shall vest in
the Surviving Corporation, and all debts, liabilities and duties of the Company
and Buyer shall become the debts, liabilities and duties of the Surviving
Corporation.

        (d) The Articles of Incorporation of the Surviving Corporation shall be
amended and restated to read the same as the Certificate of Incorporation of
Buyer in effect at the Effective Time until amended in accordance with
applicable Law, PROVIDED HOWEVER, that Section I of the amended and restated
Articles of Incorporation of the Company as the Surviving Corporation, instead
of reading the same as Section I of the Certificate of Incorporation of Buyer,
shall read as follows: "The name of the corporation is DTM Corporation." The
bylaws of the Surviving Corporation shall be amended and restated to read the
same as the bylaws of Buyer in effect at the Effective Time until amended in
accordance with applicable Law, except that all references in such Bylaws to
Buyer shall be changed to refer to DTM Corporation.

        (e) The directors of Buyer at the Effective Time shall be the initial
directors of the Surviving Corporation, each to hold office in accordance with
the Certificate of Incorporation

                                    Page 15
<PAGE>

and bylaws of the Surviving Corporation until such director's successor is duly
elected or appointed and qualified or until such director's earlier death,
resignation or removal in accordance with the Certificate of Incorporation and
bylaws of the Surviving Corporation.

        (f) The officers of Buyer at the Effective Time shall be the initial
officers of the Surviving Corporation, each to hold office in accordance with
the Certificate of Incorporation and bylaws of the Surviving Corporation until
such officer's successor is duly elected or appointed and qualified or until
such officer's earlier death, resignation or removal in accordance with the
Certificate of Incorporation and bylaws of the Surviving Corporation.

        3.2 MERGER CONSIDERATION AND CANCELLATION OF SHARES.

        At the Effective Time, pursuant to this Agreement and by virtue of the
Merger and without any action on the part of Parent, Buyer, the Company, or the
holders of any of the following securities:

        (a) Each Share issued and outstanding immediately prior to the Effective
Time (including shares of Common Stock issued upon exercise of Options and other
convertible securities of the Company, but excluding any Dissenting Shares, and
shares to be cancelled pursuant to SECTION 3.2(B)), shall be converted
automatically into the right to receive an amount in cash equal to the Offer
Price (the "PER SHARE AMOUNT"), without interest, payable to the holder thereof,
less any required withholding taxes, upon surrender of the certificate formerly
representing such share of Common Stock in the manner provided in SECTION 3.3.

        (b) Each Share held in the treasury of the Company or held by Parent or
Buyer or any other Subsidiary of Parent, 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.

        (c) Each outstanding share of common stock of Buyer shall be converted
into one (1) share of common stock of the Surviving Corporation.

        (d) If between the date of this Agreement and the Effective Time the
number of outstanding shares of capital stock of the Company shall have been
changed into a different number of shares or a different class, by reason of any
stock dividend, subdivision, reclassification, recapitalization, split-up,
combination, exchange of shares or the like other than pursuant to the Merger,
the Per Share Amount payable to each holder of Shares shall be correspondingly
adjusted.

        3.3 PAYMENT OF CASH FOR SHARES.

        (a) At the Effective Time, the Surviving Corporation shall irrevocably
deposit or cause to be deposited with a paying agent appointed by Buyer and
reasonably acceptable to the Company (the "PAYING AGENT"), as agent for the
holders of Shares to be cancelled in accordance with SECTION 3.2, cash in the
aggregate amount required to pay the Merger Consideration in respect of such
securities outstanding immediately prior to the Effective Time. Pending
distribution pursuant to SECTION 3.3(B) hereof of the cash deposited with the
Paying Agent, such cash shall be held in trust for the benefit of the holders of
the Shares converted pursuant to the

                                    Page 16
<PAGE>

Merger and such cash shall not be used for any other purposes. Promptly after
the Effective Time, the Surviving Corporation shall cause the Paying Agent to
mail to each Person who was, at the Effective Time, a holder of record of Shares
entitled to receive the Per Share Amount pursuant to SECTION 3.2 hereof, a form
of letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the certificates evidencing the Shares (the "SHARE
CERTIFICATES") shall pass, only upon proper delivery of the Share Certificate to
the Paying Agent) and instructions for use in effecting the surrender of the
Share Certificate pursuant to such letter of transmittal. Upon surrender to the
Paying Agent of a Share Certificate, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
and such other documents as may be required pursuant to such instructions, the
holder of such Share Certificate shall be entitled to receive in exchange
therefor the Per Share Amount for each Share formerly evidenced by such Share
Certificate, and such Share Certificate shall thereupon be cancelled. No
interest shall accrue or be paid on the Per Share Amount payable upon the
surrender of any Share Certificate for the benefit of the holder of such Share
Certificate and any required withholding taxes on the Per Share Amount may be
withheld by Buyer or the Paying Agent. All interest accrued in respect of the
cash deposited with the Paying Agent shall accrue to the benefit of and be paid
to the Surviving Corporation.

        (b) After surrender to the Paying Agent of any Share Certificate or
other instrument which prior to the Effective Time shall have represented any
Shares, the Paying Agent shall promptly distribute to the Person in whose name
such Share Certificate or other instrument shall have been registered, a check
representing the Merger Consideration that such Person has the right to receive
pursuant to the provisions of this ARTICLE 3. Until so surrendered and
cancelled, each such Share Certificate or other instrument shall, after the
Effective Time, be deemed to represent only the right to receive the Per Share
Amount, and until such surrender and cancellation, no cash shall be paid to the
holder of such outstanding Share Certificate or other instrument in respect
thereof. From and after the Effective Time, the holders of Shares outstanding
immediately prior to the Effective Time shall cease, except for Dissenting
Shares and otherwise as required by law, to have any rights with respect to such
Shares, other than the right to receive the Per Share Amount as provided in this
Agreement.

        (c) If payment is to be made to a Person other than the registered
holder of the Shares represented by the Share Certificate or other instrument so
surrendered in exchange therefor, it shall be a condition to such payment that
the Share Certificate or other instrument so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting such payment shall pay to the Paying Agent any transfer or other
taxes required as a result of such payment to a Person other than the registered
holder of such Shares or establish to the satisfaction of the Paying Agent that
such tax has been paid or is not payable.

        (d) After the Effective Time, there shall be no further transfers on the
stock transfer books of the Company of the Shares that were outstanding
immediately prior to the Effective Time. If, after the Effective Time, Share
Certificates representing the Shares are presented to the Surviving Corporation,
they shall be cancelled and exchanged for the Per Share Amount provided for, and
in accordance with the procedures set forth in this ARTICLE 3.

        (e) If any cash deposited with the Paying Agent for purposes of payment
in exchange for the Shares remains unclaimed six months after the Effective
Time, such cash shall

                                    Page 17
<PAGE>

be returned to the Surviving Corporation, upon demand, and any such holder who
has not converted the Shares into the Per Share Amount or otherwise received the
Per Share Amount pursuant to this Agreement prior to that time shall thereafter
look only to the Surviving Corporation for payment of the Per Share Amount.
Notwithstanding the foregoing, the Surviving Corporation shall not be liable to
any holder of Shares for any amount paid to a public official pursuant to
applicable unclaimed property laws. Any amounts remaining unclaimed by holders
of Shares seven (7) years after the Effective Time (or such earlier date
immediately prior to such time as such amounts would otherwise escheat to or
become property of any Governmental Entity) shall, to the extent permitted by
applicable Law, become the property of the Surviving Corporation, free and clear
of any claims or interest of any Person previously entitled thereto.

        (f) Any portion of the Merger Consideration made available to the Paying
Agent to pay for Shares for which dissenters' rights have been perfected as
provided in SECTION 3.4 hereof shall be returned to the Surviving Corporation
upon demand.

        (g) No dividends or other distributions with respect to capital stock of
the Company with a record date after the Effective Time shall be paid to the
holder of any unsurrendered certificate for the Shares.

        (h) In the event that any Share Certificate or other instrument
representing Shares shall have been lost, stolen or destroyed, upon the making
of an affidavit of that fact by the Person claiming such certificate or other
instrument to be lost, stolen or destroyed and, if required by the Surviving
Corporation, the posting by such holder of a bond in such reasonable amount as
the Surviving Corporation may direct as indemnity against any claim that may be
made against it with respect to such Share Certificate or other instrument, the
Paying Agent will issue in exchange for and in lieu of such lost, stolen or
destroyed certificate or other instrument representing the Shares, the Per Share
Amount, and unpaid dividends and distributions on Shares deliverable in respect
thereof, pursuant to this Agreement and the Merger, without interest and less
any required withholding taxes.

        3.4 DISSENTING SHARES.

        Notwithstanding any other provisions of this Agreement, Shares which are
issued and outstanding immediately prior to the Effective Time and which are
held by a holder who has not voted such shares of capital stock of the Company
in favor of the Merger and who has otherwise complied with the relevant
provisions of Article 5.12 of the TBCA and who, as of the Effective Time, shall
not have effectively withdrawn or lost such right to relief as a dissenting
stockholder ("Dissenting Shares") shall not be converted into a right to receive
the Per Share Amount. The holders thereof shall be entitled only to such rights
as are granted by Article 5.12 of the TBCA. Each holder of Dissenting Shares who
becomes entitled to payment for such Dissenting Shares pursuant to Article 5.12
of the TBCA shall receive payment therefor from the Surviving Corporation in
accordance with the TBCA; provided, however, that if any such holder of
Dissenting Shares (i) shall have failed to establish his entitlement to relief
as a dissenting stockholder as provided in Article 5.12 of the TBCA, (ii) shall
have effectively withdrawn his demand for relief as a dissenting stockholder
with respect to such Dissenting Shares or lost his right to relief as a
dissenting stockholder and payment for his Dissenting Shares under Article

                                    Page 18
<PAGE>

5.12 of the TBCA, or (iii) shall have failed to file a complaint with the
appropriate court seeking relief as to determination of the value of all
Dissenting Shares within the time provided in Article 5.12 of the TBCA, such
holder shall forfeit the right to relief as a dissenting stockholder with
respect to such Dissenting Shares and each such Dissenting Share shall be
converted into the right to receive the Per Share Amount from the Surviving
Corporation as provided in SECTION 3.2. The Company shall give Parent prompt
notice of any demands received by the Company prior to the Effective Time any
attempted withdrawals of such demands and any other instruments served pursuant
to the TBCA and received by the Company relating to stockholders' rights
appraisal, and Parent shall have the right to direct all negotiations and
proceedings with respect to such demands. The Company shall not, except with the
prior written consent of Parent, make any payment with respect to, or settle or
offer to settle, any such demands.

        3.5 STOCK OPTIONS.

        (a) At the Effective Time, each outstanding and unexercised option to
purchase Shares (a "COMPANY OPTION") pursuant to the existing and duly
administered 1996, 1998 and 1999 stock option plans of the Company (the "COMPANY
OPTION PLANS"), whether vested or unvested, shall be converted into an
obligation of the Company to pay, and the right of the holder thereof to
receive, in full satisfaction of each Company option, the "Cash Amount." with
respect to such Company Option. The "Cash Amount" for any Company Option shall
equal the product of (1) the excess, if any, of the Per Share Offer Amount over
the exercise price per Share of such Company Option and (2) the number of Shares
underlying such Company Option. Company shall take all actions necessary to
cause the Company's employees and directors to consent, to the extent required,
to the transactions contemplated by this SECTION 3.5 no later than immediately
prior to the Effective Time. Except as may be otherwise agreed to by Parent or
Buyer and the Company, as of the Effective Time, (A) the Company Option Plans
shall terminate, (B) the provisions in any other plan, program or arrangement
providing for the issuance or grant of any other interest in respect of the
capital stock of the Company or any or the Acquired Subsidiaries shall be
deleted and (C) no holder of Company Options or any participant in the Company
Option Plans or any other plans, programs or arrangements shall have any rights
thereunder to acquire any equity securities of the Company, the Surviving
Corporation or any subsidiary thereof. All Company Options outstanding as of the
date of this Agreement and the price at which they are exercisable are listed on
Section 3.5(a) of the Company Disclosure Letter. The Company and Parent agree
that the Cash Amounts are the sole payments that will be made with respect to or
in relation to the Company Options.

        (b) All warrants and other convertible securities to purchase shares of
Company Common Stock shall be canceled as of the Closing Date. At or before the
Effective Time, the Company shall take all actions, in a manner reasonably
satisfactory to Parent, necessary or advisable to give effect to the foregoing
provisions of this SECTION 3.5.

        (c) As soon as practicable following the Effective Time, Parent shall
cause to be mailed to the holder of each Company Option, the Cash Amount payable
with respect to such Company Option to such holder pursuant to SECTION 3.5(A)
hereof.

face of the Year 2000 Financial Statement (rather than in any notes thereto) as
adjusted for the passage of time through the Closing Date in accordance with the

        (u) take or agree in writing or otherwise to take any of the actions
described in SECTIONS 6.2(A) THROUGH 6.2(T) (and it shall not take any action
that would make any of the representations or warranties of the Company
contained in this Agreement (including the exhibits hereto) untrue or
incorrect).

        6.3 ACCESS TO INFORMATION.

        (a) Upon reasonable prior notice, the Company shall afford reasonable
access to the officers, employees, accountants, counsel and other
representatives of Parent and Buyer (including financing sources and their
employees, accountants, counsel and other representatives), during normal
business hours during the period prior to the Effective Time, to all its
properties, books, Contracts, and records; provided that the Company will not be
required to provide such information to the extent that, in the opinion of the
Company's legal counsel, such disclosure would constitute a waiver of the
attorney-client privilege with respect to the subject matter of underlying the
information sought to be disclosed or materially and adversely prejudice the
Company in any material Action.

        (b) During the period prior to the Effective Time, the Company shall
promptly furnish to Parent and Buyer (i) a copy of each report, schedule,
registration statement and other document in advance of filing it with the SEC,
and shall provide Parent and Buyer a reasonable opportunity to review and
comment upon such document, during such period, (ii) a copy of each document
received by it from the SEC, during such period, and (iii) all other information
concerning its business, properties and personnel as Parent and Buyer may
reasonably request.

        (c) That certain Confidentiality Agreement dated March 17, 2001, by and
between the Company and Parent (the "CONFIDENTIALITY AGREEMENT") shall apply
with respect to the information furnished pursuant to this SECTION 6.3 and
otherwise pursuant to this Agreement.

        6.4 ACQUISITION PROPOSAL.

        (a) The Company shall not, nor shall it authorize or permit any Company
Subsidiary to, nor shall it authorize or permit any officer, director or
employee of, or any investment banker, attorney or other advisor, agent or
representative (collectively, "REPRESENTATIVES") of, the Company or any Company
Subsidiary to, (i) directly or indirectly solicit, initiate or encourage the
submission of, any Acquisition Proposal (as defined below), (ii) enter into any
agreement with respect to any Acquisition Proposal or (iii) directly or
indirectly participate in any discussions or negotiations regarding, or furnish
to any person any information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes,

                                    Page 40
<PAGE>

or may reasonably be expected to lead to, any Acquisition Proposal; provided,
however, that nothing in this SECTION 6.4 or elsewhere in this Agreement shall
prohibit the Company Board from complying with Rules 14d-9 and 14e-2 under the
Exchange Act with regard to a tender or exchange offer not made in violation of
this SECTION 6.4; and provided, further, that nothing in this SECTION 6.4 or
elsewhere in this Agreement shall prohibit the Company, before the expiration of
the Offer or adoption of this Agreement by the Company Shareholders, if
applicable, from furnishing information regarding the Company or entering into
negotiations or discussions with, any person in response to an Acquisition
Proposal made, submitted, or announced by such person (and not withdrawn) or
endorsing and/or recommending, or simultaneously with a termination of this
Agreement pursuant to SECTION 9.1(C), entering into an agreement accepting or
providing for, a Superior Proposal, and any such actions enumerated in this
provision shall not be considered a Breach of this Agreement if and to the
extent that each of the following conditions is satisfied: (1) such Acquisition
Proposal is not attributable to a Breach by the Company of this SECTION 6.4(A)
or SECTION 6.4(B); (2) the Board of Directors of the Company concludes in good
faith, after consultation with its outside legal counsel, that it is reasonably
likely that the failure to take such action would constitute a Breach of its
fiduciary duties to the Company Shareholders under applicable Law; (3) prior to
furnishing any such information to, or entering into discussions or negotiations
with, such person, the Company gives Parent written notice of the identity of
such person, the terms and conditions of such Acquisition Proposal and the
Company's intention to furnish information to, or enter into discussions or
negotiations with, such Person; (4) the Company receives from such Person an
executed confidentiality agreement which shall not in any way restrict the
Company from complying with its disclosure obligations under this Agreement and
which shall contain customary limitations on the use and disclosure of all
nonpublic written and oral information furnished to such Person by or on behalf
of the Company, restrictions on trading and hostile take-over activities and
other terms no less favorable to the Company than those set forth in the
Confidentiality Agreement; and (5) contemporaneously with furnishing any such
information to such Person, the Company furnishes such information to Parent (to
the extent that such information has not been previously furnished by the
Company to Parent). Subject to the foregoing provisions of this SECTION 6.4(A),
the Company shall, and shall cause its Representatives to, cease immediately all
existing activities, discussions and negotiations with Persons other than Parent
and Buyer regarding any proposal that constitutes, or may reasonably be expected
to lead to, a Acquisition Proposal, and will take the necessary steps to inform
the Persons referred to above of the obligations undertaken in this SECTION 6.4.

        (b) Neither the Company Board nor any committee thereof shall (i)
withdraw or modify, or propose to withdraw or modify, in a manner adverse to
Parent or Buyer, the approval or recommendation by the Company Board or any such
committee of this Agreement, the Offer or the Merger, (ii) approve any letter of
intent, agreement in principle, acquisition agreement or similar agreement
relating to any Acquisition Proposal, or (iii) approve or recommend, or propose
to approve or recommend, any Acquisition Proposal. Notwithstanding the
foregoing, if, prior to the acceptance for payment of Shares pursuant to the
Offer, the Company receives a Superior Proposal and a majority of the directors
of the Company determine in good faith, after consultation with outside legal
counsel, that it is reasonably likely that the failure to do so would constitute
a Breach of their fiduciary duties to Company Shareholders imposed by applicable
Law, the Company Board may withdraw its approval or recommendation of the Offer,
the Merger and this Agreement and, in connection therewith, approve or recommend
such Superior

                                    Page 41
<PAGE>

Proposal, provided, that the Company Board shall give Parent two Business Days
notice prior to withdrawing its recommendation or entering into an agreement
with respect to or recommending a Superior Proposal; and pay to Parent the
Termination Fee Provided for in SECTION 9.3(A) pursuant to SECTION 9.3(D).

        (c) The Company promptly shall advise Parent of any Acquisition Proposal
or any inquiry with respect to or that could lead to any Acquisition Proposal,
the identity of the person or group making any such Acquisition Proposal or
inquiry and the material terms of any such Acquisition Proposal or inquiry. The
Company shall (i) keep Parent fully informed of the status, including any change
to the details, of any such Acquisition Proposal or inquiry and (ii) provide to
Parent as soon as practicable after receipt or delivery thereof with copies of
all correspondence with other written material sent or provided (unless
previously provided) to the Company from any third party in connection with any
Acquisition Proposal or sent or provided by the Company to any third party in
connection with any Acquisition Proposal.

        (d) Nothing contained in this SECTION 6.4 shall prohibit the Company
from taking and disclosing to its Shareholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any required
disclosure to the Company's Shareholders if, in the good faith judgment of the
Company Board, after receiving advice from outside legal counsel, the failure so
to disclose would constitute a Breach of its fiduciary duties under applicable
law.

        (e)    For purposes of this Agreement:

        "ACQUISITION PROPOSAL" means any offer or proposal (other than an offer
or proposal by Parent or an Affiliate of Parent) for (i) a merger, acquisition
consolidation, or similar transaction involving any equity security of the
Company or (ii) the acquisition (other than an acquisition by Parent or an
Affiliate of Parent) of all or substantially all of the assets of the Company.

        "SUPERIOR PROPOSAL" means an unsolicited bona fide Acquisition Proposal
made by a third party that the Board of Directors of the Company determines in
good faith has the good faith intent to proceed with negotiations, and financial
and other capabilities to consummate such Acquisition Proposal, taking into
account, among other things, the legal, financial, regulatory and other aspects
of such Acquisition Proposal, (i) on terms that a majority of the directors of
the Company Board determines in its good faith judgment to represent superior
value for the holders of the Shares than the Transactions (based on the written
opinion, with only customary qualifications, of an independent financial advisor
as to such proposal's financial superiority), and (ii) that is reasonably
capable of being completed, taking into account all financial, regulatory, legal
and other aspects of such proposal.

        6.5 CHARGES, FEES, AND PREPAYMENT OBLIGATIONS.

        The Company will, prior to the Closing, take such commercially
reasonable steps as are necessary to ensure that (i) no sums are owed or payable
by the Acquired Entities to any Person in the nature of a transfer charge or
processing fee with respect to any Contracts of the Acquired Entities, and (ii)
no sums are owed or payable as a prepayment penalty if Parent or the Acquired
Entities elect to prepay any Liability of the Acquired Entities that is
outstanding as of the Closing Date.

        6.6 FINANCING.

        Parent agrees to use its reasonable best efforts to obtain, as promptly
as practical, on terms reasonably satisfactory to Parent, the Financing
Commitments. Parent will consult with and provide periodic reports at reasonable
intervals to the Company regarding the status of such financing. Such
consultation and reports may be made orally, by email or other communications at
the convenience of the Parties.

        6.7 COVENANTS TO SATISFY CONDITIONS.

        Each of the Company and Parent will use reasonable best efforts to
ensure, and to cause their respective Affiliates to ensure, that the conditions
set forth in Annex A and ARTICLE 8 hereof are satisfied, insofar as such matters
are within the control of such party. Parent and the Company further covenant
and agree, with respect to any pending or Threatened Action, preliminary or
permanent injunction or other Order, that would adversely affect the ability of
the Parties to consummate the Transactions, to use reasonable best efforts to
prevent or lift the entry, enactment or promulgation thereof, as the case may
be.

        6.8 DISCLOSURE PRIOR TO CLOSING.

        In the event that, at any time prior to the Closing, the Company or
Parent becomes aware of any matter that, if existing or known as of the date of
this Agreement, would have been required to be set forth or described in the
Company Disclosure Letter or the Parent Disclosure Letter hereto or would
otherwise have rendered any representation or warranty false, or would
materially alter or delay the Transaction, such Party shall promptly provide
written notice of such matters to the other Party. However, no such notice
provided under this SECTION 6.8 shall be deemed to cure any Breach of any
representation or warranty made in this Agreement whether for purposes of
determining whether or not the conditions set forth in ARTICLE 8 hereof have
been satisfied or otherwise. In addition, the Company shall promptly provide
written notice of any events occurring after the date hereof and prior to the
Closing that individually or in the aggregate have had or are reasonably
expected to have a Material Adverse Effect on the Company.

        6.9 PUBLICITY.

        The initial press release relating to this Agreement shall be a joint
press release in a form mutually agreeable to Parent and the Company and Parent
and the Company shall, subject to their respective legal obligations of public
companies, use reasonable efforts to agree upon the text of any other press
release before issuing any such press release or otherwise making public
statements with respect to the transactions contemplated hereby and in making
any filings with any federal or state governmental or regulatory agency or with
any national securities exchange with respect thereto.

        6.10 PREPARATION OF THE COMPANY PROXY STATEMENT; COMPANY SHAREHOLDERS
MEETING; MERGER WITHOUT A COMPANY SHAREHOLDERS MEETING.

        (a) If adoption of this Agreement is required by applicable Law, the
Company will, as soon as practicable following the acceptance for payment of and
payment for Shares by

                                    Page 43
<PAGE>

Buyer in the Offer, duly call, give notice of, convene and hold a meeting of the
Company Shareholders for the purpose of adopting this Agreement or, in lieu of
such meeting, Parent and Buyer, as soon as practicable following the Funding
Date (as defined below), shall cause this Agreement to be adopted by written
consent of stockholders. At such stockholders meeting (or in connection with any
consent in lieu thereof), Parent shall cause all of the Shares then owned by
Parent or Buyer to be voted in favor, or consented to, the adoption of this
Agreement. In the event that adoption of this Agreement requires a meeting of
the Company Shareholders, then the Company and Parent will, as soon as
practicable following the acceptance for payment of and payment for the Shares
by Buyer in the Offer (the date on which such acceptance and payment shall occur
shall be referred to herein as the "FUNDING DATE"), prepare and file a Proxy
Statement (the "COMPANY PROXY STATEMENT") in preliminary form with the SEC. The
Company agrees that Parent shall be given reasonable opportunity to review and
comment on the Company Proxy Statement and such other materials and to approve
the Company Proxy Statement and such other materials prior to their filing and
thereafter to participate in discussions concerning the comments of the SEC
staff and to approve all responses thereto. The Company will use all reasonable
efforts to respond to all SEC comments with respect to the Company Proxy
Statement and to cause the Company Proxy Statement to be mailed the Company
Shareholders at the earliest practicable date. Parent will provide the Company
with the information concerning Parent and Buyer required to be included in the
Company Proxy Statement.

        (b) Notwithstanding the foregoing clause (a), in the event that Parent
and Buyer shall acquire in the aggregate at least 90% of the Shares in the
Offer, the Parties agree to take all necessary and appropriate action to cause
the Merger to become effective, as soon as practicable after the expiration of
the Offer, without a meeting of the Company Shareholders, in accordance with
Section 5.03.G.of the TCBA.

        6.11 INDEMNIFICATION AND DIRECTORS' AND OFFICER'S INSURANCE.

        (a) After the acceptance of Shares for payment in the Offer, the Company
shall indemnify and hold harmless (and shall also advance expenses as incurred
to the fullest extent permitted under applicable Law to), to the extent not
covered by insurance, each person who is now or has been prior to the date
hereof or who becomes prior to the Effective Time an officer or director of the
Company or any of the Acquired Subsidiaries (the "INDEMNIFIED PERSONS") against
(i) all losses, claims, damages, costs, expenses (including counsel fees and
expenses), settlement, payments or liabilities arising out of or in connection
with any claim, demand, action, suit, proceeding or investigation based in whole
or in part on or arising in whole or in part out of the fact that such person is
or was an officer or director of the Company or any of the Acquired
Subsidiaries, whether or not pertaining to any matter existing or occurring at
or prior to the Effective Time and whether or not asserted or claimed prior to
or at or after the Effective Time ("INDEMNIFIED LIABILITIES"); and (ii) all
Indemnified Liabilities based in whole or in part on or arising in whole or in
part out of or pertaining to this Agreement or the transactions contemplated
hereby, in each case to the fullest extent required or permitted under
applicable Law. Nothing contained herein shall make Parent, Buyer, the Company
or the Surviving Corporation, an insurer, a co-insurer or an excess insurer in
respect of any insurance policies which may provide coverage for Indemnified
Liabilities, nor shall this SECTION 6.11 relieve the obligations of any insurer
in respect thereto. The parties hereto intend, to the extent not prohibited by
applicable

                                    Page 44
<PAGE>

Law, that the indemnification provided for in this SECTION 6.11 shall apply
without limitation to negligent acts or omissions by an Indemnified Person. Each
Indemnified Person is intended to be a third party beneficiary of this SECTION
6.11 and may specifically enforce its terms. This SECTION 6.11 shall not limit
or otherwise adversely affect any rights any Indemnified Person may have under
any agreement with the Company or under the Company's Organizational Documents
as presently in effect.

        (b) From and after the Effective Time, Parent shall cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to any indemnification agreements between the Company and its directors
and officers as of or prior to the date hereof (or indemnification agreements in
the Company's customary form for directors joining the Company Board prior to
the Effective Time) and any indemnification provisions under the Company's
Organizational Documents as in effect immediately prior to the Effective Time.
The Surviving Corporation's aggregate obligation to indemnify and hold harmless
all Indemnified Persons for all matters to which such Indemnified Persons may be
entitled to be indemnified or held harmless under subsections (a) and (b) of
this SECTION 6.11 shall in no event exceed the net worth of the Company at the
Effective Time.

        (c) For a period of six (6) years after the Effective Time, Parent will
maintain or cause the Surviving Corporation to maintain in effect, if available,
directors' and officers' liability insurance covering those persons who, as of
immediately prior to the Effective Time, are covered by the Company's directors'
and officers' liability insurance policy (the "INSURED PARTIES") on terms no
less favorable to the Insured Parties than those of the Company's present
directors' and officers' liability insurance policy; provided however, that in
no event will Parent or the Company be required to expend in excess of two
hundred percent (200%) of the annual premium currently paid by the Company for
such coverage (or such coverage as is available for two hundred percent (200%)
of such annual premium); provided further, that, in lieu of maintaining such
existing insurance as provided above, Parent, at its election, may cause
coverage to be provided under any policy maintained for the benefit of Parent or
any of its subsidiaries, so long as the terms are not materially less
advantageous to the intended beneficiaries thereof than such existing insurance.

        (d) Neither Parent nor any of its affiliates shall be obligated to
guarantee the payment or performance of the Company's obligations under clauses
(a) or (b) of this SECTION 6.11 so long as the Company honors such obligations
to the extent of its shareholders' equity at the Effective Time, and neither
Parent nor any such affiliate shall have any liability or obligation to any
Indemnified Person arising from the Company's Breach of, or inability to perform
its obligations under, such clauses in excess of the difference between the
shareholders' equity of the Company at the Effective Time and the aggregate of
all amounts paid by the Company in satisfaction of such obligations. The
provisions of this SECTION 6.11 are intended to be for the benefit of, and will
be Enforceable by, each Indemnified Person and the heirs and representatives of
such Indemnified Person. Parent will not permit the Company to merge or
consolidate with any other Person unless the Company will ensure that the
surviving or resulting entity assumes the obligations imposed by this SECTION
6.11.

        (e) If any Action is brought for the enforcement of the provisions of
this Section 6.11 by any Indemnified Party, as a condition to bringing such
Action, such Indemnified Party

                                    Page 45
<PAGE>

shall agree that the successful or prevailing party in any such Action shall be
entitled to recover, in addition to any other relief to which he or it may be
entitled, all of his or its actual out of pocket costs and expenses (including
attorneys fees) incurred in connection with such Action.

        6.12 EMPLOYEE BENEFITS.

        (a) Parent and Buyer agree that, effective as of the Effective Time, all
Retained Employees shall become eligible employees and entitled to all benefits
under Employee Benefit Plans of Parent generally available to all employees of
Parent and its Subsidiaries

        (b) Prior to the Effective Time, the Company shall adopt severance plans
and/or enter into Severance Agreements substantially as provided in SECTION
6.12(B) of the Company Disclosure Letter (collectively referred to as the
"SEVERANCE ARRANGEMENTS"). Parent and Buyer agree to honor, and cause the
Surviving Corporation to honor, without modification, all Severance
Arrangements. Parent and Buyer acknowledge that the consummation of the Offer
shall constitute a "Change in Control") for purpose of the Severance
Arrangements.

        (c) Subject to the terms of any Employee Benefit Plan and ERISA, if any
employee of the Company, or any of its Subsidiaries becomes a participant in any
Employee Benefit Plan, of Parent or the Surviving Corporation, such employee
shall be given credit under such plan for all service prior to the Effective
Time with the Company and its Subsidiaries, or any predecessor employer (to the
extent such credit was given by the Company), for purposes of eligibility and
vesting (but not for benefit accrual purposes) for which such service is either
taken into account or recognized.

        (d) To the extent practicable, Parent and the Surviving Corporation
shall administer their medical plans ("Buyer Medical Plans") so as to coordinate
deductibles, out-of-pocket maximums, and maximum benefit restrictions so that:
(i) Retained Employees receive credit under the Buyer Medical Plans toward any
deductibles under the Buyer Medical Plans for deductibles paid under any of the
medical, dental and prescription drug plans maintained by the Company or any
Acquired Entities ("Company Medical Plans") on or prior to the Closing which,
had the Retained Employees been covered by the Buyer Medical Plans at that time,
would have been taken into account by the Buyer Medical Plans, (ii) Retained
Employees receive credit for their eligible out-of-pocket costs with respect to
eligible claims incurred under the Company Medical Plans on or prior to the
Closing which, had the Retained Employee been covered by the Buyer Medical Plans
at that time would have been. taken into account by the Buyer Medical Plans
toward any out-of-pocket maximums under the Buyer Medical Plans, and (iii)
Retained Employees are credited with benefits received under the Company Medical
Plans on or prior to the Closing which, had the Retained Employee been covered
by the Buyer Medical Plans at that time, would have been taken into account by
the Buyer Medical Plans for purposes of applying the maximum benefit
restrictions under the Buyer Medical Plans.

        6.13 WORKS IN PROGRESS/FINISHED GOODS.

                                    Page 46
<PAGE>

               The Company shall take all commercially reasonable actions agreed
to in consultation with Parent in order to minimize the amount of work in
process and inventory that any Acquired Entity shall have in its possession or
control (whether in inventory or otherwise) as of the Effective Time.

        (c) by Parent, if (i) the Company Board (A) withdraws, modifies or
changes (including by amendment of the Schedule 14D-9) its recommendation of the

Shares by the Company Shareholders who are party to the Tender Agreement shall
not be deemed to trigger this clause (B);

        (d) by the Company, if, prior to the acceptance of and payment for the
Shares pursuant to the Offer, (x) the Company shall have entered into an
agreement with respect to a Superior Proposal or the Company Board shall have

<PAGE>

Company first makes the payment of the Termination Fee as required by Section

termination;

        (e) by the Company if there has been a material Breach by Parent or
Buyer of any representation, warranty, covenant or agreements set forth in this

material respects within five Business Days following receipt of notice of such

failure of the condition set forth in clause (e) of Annex A hereto to be
satisfied or if, prior to the consummation of the Offer, the Company shall have
failed to perform its covenants of other agreements continued in this Agreement
which failure to perform would give rise to the failure of the condition set

incapable of being cured in all material respects within five Business Days
following receipt of notice of such Breach.

        9.2 MANNER AND EFFECT OF TERMINATION.

        (a) Termination shall be effected by the giving of written notice to
that effect by the party seeking termination. If this Agreement is validly
terminated and the transactions contemplated hereby are not consummated, this
Agreement shall become null and void and of no further force and effect and no
party shall be obligated to the others hereunder; PROVIDED, HOWEVER, that
termination shall not affect (i) the rights and remedies available to a party as
a result of the Breach by the other party or parties hereunder, (ii) the
provisions of SECTIONS 10.2, 0, AND 10.13 hereof, or (iii) the obligations of
the Parties pursuant to SECTION 9.3 below.

        9.3 CERTAIN PAYMENTS UPON TERMINATION.

        (a) In the event that: (A) the Company terminates this Agreement under
SECTION 9.1(D) or (B) Parent terminates this Agreement under SECTION 9.1(C)(I),
the Company shall pay to Parent a termination fee equal to $1,025,000 plus all
actual out of pocket expenses (including, but not limited to, fees of legal
counsel, accountants and financial and other advisors) incurred by Parent and
any of its Affiliates in connection with the negotiation and execution of this
Agreement and the exhibits hereto and the planned consummation of the necessary
financing therefor and the Transactions ("Parent Expenses"), provided that such
fee shall not exceed Two Million and No/100 Dollars ($2,000,000) in the
aggregate (the "TERMINATION FEE").

        (b) In the event that (A) a Termination Fee is not otherwise payable to
Parent pursuant to SECTION 9.3(A) and (B) (i) Parent terminates this Agreement
under SECTION 9.1(F), or (ii) this Agreement is terminated due to a failure of
the condition set forth in SECTION 8.1(E), the Company shall pay to Parent an
amount equal to the Parent Expenses; provided, however, the amount payable
pursuant to this Section 9.3 (b) shall not exceed $500,000.

        (c) In the event that the Company terminates this Agreement under
SECTION 9.1(E), Parent shall pay to Company all actual out of pocket expenses
(including, but not limited

                                    Page 49
<PAGE>

to, fees of legal counsel, accountants and financial and other advisors)
incurred by Company and any of its Affiliates in connection with the negotiation
and execution of this Agreement and the exhibits hereto and the planned
consummation of the Transactions ("Company Expenses"); provided, however, the
amount payable pursuant to this Section 9.3(c) shall not exceed $500,000.

        (d) All payments required to be made hereunder shall be made by wire
transfer of immediately available funds within five (5) Business Days of the
event giving rise to the payment of such Expenses. Each of Parent and the
Company acknowledges that the agreements contained in this SECTION 9.3 are an
integral part of the Transactions and that, without said agreements, neither
Parent nor the Company would have entered into this Agreement; accordingly, if
either Party fails promptly to pay the Termination Fee or Expenses due pursuant
to this SECTION 9.3, and, in order to obtain such payment, the other Party
commences an Action which results in a judgment against the Party who has failed
to make such payments, the non-prevailing Party will pay to the prevailing
Party, its reasonable expenses (including attorneys' fees and expenses) in
connection with such Action, together with interest on the amounts due hereunder
at the legal rate determined by the court rendering such judgment.

                                  MISCELLANEOUS

        10.1 DISCLOSURE LETTERS.

        (a) The disclosures in the Disclosure Letters, and those in any
supplement thereto, relate only to the representations and warranties in the
Section or paragraph of the Agreement to which they expressly relate and not to
any other representation or warranty in this Agreement.

        (b) If there is any inconsistency between the statements in the body of
this Agreement and those in the Disclosure Letters (other than an exception
expressly set forth as in the Disclosure Letters with respect to a specifically
identified representation or warranty), the statements in the body of this
Agreement will control.

        (c) Nothing in the Disclosure Letters will be deemed adequate to
disclose an exception to a representation or warranty made herein, unless the
Disclosure Letters identify the exception with reasonable particularity and
describes the relevant facts in reasonable detail.

        (d) The mere listing (or inclusion of a copy) of a document or other
item in a Disclosure Letter will not be deemed adequate to disclose an exception
to a representation or warranty made in this Agreement (unless the
representation or warranty pertains to the existence of the document or other
item itself).

        10.2 ENTIRE AGREEMENT.

        This Agreement, together with the Exhibits, Annexes and Disclosure
Letters hereto and the certificates, documents, instruments and writings that

damaged irreparably if any provision of this Agreement is not performed in
accordance with its specific terms or is otherwise Breached. Accordingly, each
Party agrees that the other Parties will be entitled to an injunction or
injunctions to prevent Breaches of the provisions of this Agreement and to
enforce specifically this Agreement and its terms and provisions in any Action
instituted in any court of the United States or any state thereof having
jurisdiction over the Parties and the matter, subject to SECTION 0, in addition
to any other remedy to which they may be entitled, at Law or in equity.

        10.7 TIME.

        Time is of the essence in the performance of this Agreement.

        10.8 COUNTERPARTS.

        This Agreement may be executed in two or more counterparts, each of
which will be deemed an original but all of which together will constitute one
and the same instrument.

        10.9 HEADINGS.

        The article and section headings contained in this Agreement are
inserted for convenience only and will not affect in any way the meaning or
interpretation of this Agreement.

        10.10 GOVERNING LAW.

                                    Page 52
<PAGE>

        This Agreement and the performance of the Transactions and obligations
of the Parties hereunder will be governed by and construed in accordance with
the laws of the State of Delaware, without giving effect to any choice of Law
principles.

        10.11 AMENDMENTS AND WAIVERS.

        No amendment, modification, replacement, termination or cancellation of
any provision of this Agreement will be valid, unless the same will be in
writing and signed by Parent and the Company. No waiver by any Party of any
default, misrepresentation, or Breach of warranty or covenant hereunder, whether
intentional or not, may be deemed to extend to any prior or subsequent default,
misrepresentation, or Breach of warranty or covenant hereunder or affect in any
way any rights arising because of any prior or subsequent such occurrence.

        10.12 SEVERABILITY.

        The provisions of this Agreement will be deemed severable and the
invalidity or unenforceability of any provision will not affect the validity or
enforceability of the other provisions hereof; provided that if any provision of
this Agreement, as applied to any Party or to any circumstance, is adjudged by a
Governmental Entity, arbitrator, or mediator not to be Enforceable in accordance
with its terms, the Parties agree that the Governmental Entity, arbitrator, or
mediator making such determination will have the power to modify the provision
in a manner consistent with its objectives such that it is Enforceable, and/or
to delete specific words or phrases, and in its reduced form, such provision
will then be Enforceable and will be enforced.

        10.13 EXPENSES.

        Except as otherwise expressly provided in this Agreement, each Party
will bear its own costs and expenses incurred in connection with the
preparation, execution and performance of this Agreement and the Transactions
including all fees and expenses of agents, representatives, financial advisors,
legal counsel and accountants.

        10.14 CONSTRUCTION.

        The Parties have participated jointly in the negotiation and drafting of
this Agreement. If an ambiguity or question of intent or interpretation arises,
this Agreement will be construed as if drafted jointly by the Parties and no
presumption or burden of proof will arise favoring or disfavoring any Party
because of the authorship of any provision of this Agreement. The word
"including" means "including without limitation." Pronouns in masculine,
feminine, and neuter genders will be construed to include any other gender, and
words in the singular form shall be construed to include the plural and vice
versa, unless the context otherwise requires. The words "this Agreement,"
"herein," "hereof," "hereby," "hereunder," and words of similar import refer to
this Agreement as a whole and not to any particular subdivision unless expressly
so limited. The Parties intend that each representation, warranty, and covenant
contained herein will have independent significance. If any Party has Breached
any representation, warranty, or covenant contained herein in any respect, the
fact that there exists another representation, warranty or covenant relating to
the same subject matter (regardless of the relative levels of specificity) which
the Party has not Breached will not detract from or mitigate the fact that the
Party is in Breach of the first representation, warranty, or covenant.

date first above written.

        Capitalized terms used in this Annex A have the meanings set forth in

the case of any of the foregoing existing at the time of commencement of the
Offer, a material acceleration or worsening thereof;

        (d) there shall have occurred any Material Adverse Change (or any
development that, insofar as reasonably can be foreseen, is reasonably likely to
result in any Material Adverse Change) in the consolidated financial condition,
businesses, or results of operations of the Acquired Entities, taken as a whole;

        (e) (i) it shall have been publicly disclosed that the beneficial
ownership (determined for the purposes of this paragraph (e) as set forth in

forth in Sections 5.5 and 5.7 of the Merger Agreement shall not be true and
correct as if such representations and warranties were made at the time of such
determination (except as to any such representation or warranty that speaks as
of a specific date, which must be untrue or incorrect as of such date); or (ii)
any of the other representations and warranties of the Company set forth in the
Merger Agreement, when read without any exception or qualification as to
materiality or reference to Material Adverse Effect, shall not be true and
correct as if such representations and warranties were made at the time of such
determination (except as to any such representation and warranty which speaks as
of a specific date, which must be untrue or incorrect as of such date) except
where the failure to be so true and correct would not

                                    Page 2
<PAGE>

individually or in the aggregate reasonably be expected to have a Material
Adverse Effect on the Company;

        (g) the Company shall have failed to perform in any material respect any
material obligation or to comply in any material respect with any material
agreement or covenant of the Company to be performed or complied with by it
under the Merger Agreement, which Breach has not been cured in all material
respects within five (5) Business Days following receipt by the Company of
written notice of such Breach; or

        (h) the Merger Agreement shall have been terminated in accordance with
its terms or the Company and Buyer and Parent shall have reached an agreement
that the Offer or Merger Agreement be terminated;

        (i) Parent shall have made or obtained all financing necessary to fund
all financial obligations arising in connection with the consummation of the
Offer, Merger and other Transactions.

The foregoing conditions are for the benefit of Parent and Buyer and may be
asserted by Parent or Buyer regardless of the circumstances giving rise to any
such conditions and other than clauses (i) and (ii) of the paragraph of this
Annex A may be waived by Parent or Buyer, in whole or in part, at any time and
from time to time in their reasonable discretion, in each case, subject to the
terms or the Merger Agreement. The conditions in clauses (i) and (ii) of the
second paragraph of this Annex A may not be waived without the written consent
of the Company. The failure by Parent or Buyer at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right and each
such right shall be deemed an ongoing right which may be asserted at any time
and from time to time.
