   and any Shares described in this Section 1.6(b) issued and outstanding
   immediately before the Effective Time shall cease to be outstanding and shall
   automatically be canceled and retired, and each certificate ("Certificate")
   previously evidencing such Shares (other than Dissenting Shares and Shares
   described in this Section 1.6(b) ("Converted Shares") shall thereafter solely
   represent the right to receive the Merger Consideration pursuant to this
   Section 1.6(a) of this Agreement.  The holders of Certificates shall cease to
   have any rights with respect to such Converted Shares except as otherwise
   provided herein or by law.

       Section 1.7.  Dissenting Shares.
                     ----------------- 

       (a) Notwithstanding any provision of this Agreement to the contrary, any
Shares held by a holder (a "Dissenting Shareholder") who has demanded and
perfected his demand for appraisal of his Shares in accordance with Sections 471
and 473 of the MBCA and as of the Effective Time has neither effectively
withdrawn nor lost his right to such appraisal shall not represent a right to
receive the aggregate Merger Consideration for such Shares pursuant to
Section 1.6 above, but in lieu thereof the holder thereof shall be entitled to
only such rights as are granted by the MBCA.  Acquiror shall make any and all
payments to holders of Shares with respect to such demands.

       (b) Notwithstanding the provisions of Section 1.7(a) above, if any
Dissenting Shareholder demanding appraisal of such Dissenting Shareholder's
Shares ("Dissenting Shares") under the MBCA shall effectively withdraw or lose
(through failure to perfect or otherwise) his right to appraisal, then as of the
Effective Time or the occurrence of such event, whichever later occurs, such
Dissenting Shares shall automatically be converted into and represent only the
right to receive the Merger Consideration as provided in Section 1.6 above upon
surrender of the certificate or certificates representing such Dissenting
Shares.

       (c) The Company shall give Acquiror prompt notice of any demands by a
Dissenting Shareholder for payment, or notices of intent to demand payment
received by the Company under Sections 473 of the MBCA and Acquiror shall have
the right to participate in all negotiations and proceedings with respect to
such demands.  The Company shall not, except with the prior written consent of
Acquiror (which will not be unreasonably withheld or delayed) or as otherwise
required by law, make any payment with respect to, or settle, or offer to
settle, any such demands.

       Section 1.8.  Company Plans.
                     ------------- 

       (a) Stock Options.  Upon the consummation of the Merger, each option to
           -------------                                                      
acquire Shares outstanding immediately prior to the Effective Time under the
Company's 1992 Long-Term Incentive and Stock Option Plan, as amended (the "ISO
Plan") and the Company's 1992 Directors' Stock Option Plan, as amended (the
"Directors' Plan"), whether vested or unvested (each, an "Option," collectively,
the "Options"), shall automatically become immediately vested and exercisable
and each holder of an Option shall have the right to receive from Acquiror a
cash payment (less applicable withholding taxes) in an aggregate amount equal to
the difference between the Merger Consideration less the exercise price per
Share applicable to such Option for all Shares subject to the Option as
expressly stated in the applicable stock option agreement or other agreement
(the "Option Consideration").  The Company shall take such other actions
(including, without limitation, giving requisite notices to holders of Options
advising them of such accelerated vesting and rights pursuant to this Section
1.8) as are necessary to fully advise holders of Options of their rights under
this Agreement and the Options and to facilitate their timely exercise of such
rights.  From and after the Effective Time, other than as expressly set forth in
this Section 1.8, no holder of an Option shall have any other rights in respect
thereof other than to receive payment for his Options equal to the Option
Consideration, and the Surviving Corporation shall take all reasonably necessary
actions to terminate the Company's stock option plans and similar arrangements.

       (b) Employee Stock Purchase Plan.  Outstanding purchase rights under the
           ----------------------------                                        
Company's 1992 Employee Stock Purchase Plan, as amended (the "ESPP"), shall be
exercised upon the earlier of (i) the next scheduled purchase date under the
ESPP or (ii) immediately prior to the Effective Time, and each participant in
the ESPP shall accordingly be issued Shares at that time which shall be
cancelled at the Effective Time and converted into the right to receive the
Merger Consideration for those Shares.  The ESPP shall terminate with such
exercise date, and no purchase rights shall be subsequently granted or exercised
under the Company ESPP.

       Section 1.9.  Surrender of Securities; Funding of Payments; Stock
                     ---------------------------------------------------
                     Transfer Books.
                     -------------- 

       (a) Pursuant to an agreement reasonably satisfactory to the Company and
Acquiror entered before the Effective Time, the Company shall designate a bank
or trust company reasonably acceptable to Acquiror to act as agent for the
holders of the Shares and Options (the "Exchange Agent") for the purpose 

                                      A-3
<PAGE>
 
of exchanging Certificates for the Merger Consideration and documents
representing Options (the "Option Agreements") for the Option Consideration. The
fees and expenses of the Exchange Agent shall be paid by Acquiror and Acquiror
shall indemnify the Exchange Agent and the Company against actions taken by the
Exchange Agent pursuant hereto other than for acts or omissions which constitute
willful misconduct or gross negligence, pursuant to the agreement with the
Exchange Agent.

       (b) At the Effective Time, Acquiror shall remit to the Exchange Agent an
amount equal to (i) the aggregate Merger Consideration and Option Consideration
necessary to pay the holders of the Converted Shares and Options  (collectively,
the "Payment Fund").

       (c) Acquiror agrees that, as soon as practicable after the Effective Time
and in no event later than five business days thereafter, the Surviving
Corporation shall cause the distribution to holders of record of the
Certificates and Option Agreements (as of the Effective Time) of a form of
letter of transmittal and other appropriate materials and instructions for use
in effecting the surrender of the Certificates for payment of the Merger
Consideration therefor and in effecting the surrender of the Option Agreements
for payment of the Option Consideration therefor.   In the event any Certificate
or Option Agreement shall have been lost or destroyed, the Exchange Agent,
subject to such other conditions as the Surviving Corporation may reasonably
impose (including the posting of an indemnity bond or other surety in favor of
the Surviving Corporation with respect to the Certificate alleged to be lost or
destroyed), shall be authorized to accept an affidavit from the record holder of
such Certificate or Option Agreement in a form reasonably satisfactory to
Acquiror.  Upon the surrender of each such Certificate formerly representing
Shares, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the Exchange Agent shall
pay to holders of such Certificates out of the Payment Fund the Merger
Consideration multiplied by the number of Converted Shares represented by such
Certificates, less any amounts required to be held pursuant to applicable tax
laws.  Upon the surrender of each such Option Agreement formerly representing
Options, together with a letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the Exchange Agent shall
pay such holders the Option Consideration multiplied by the number of Shares for
which such Options were exercisable as of the Effective Time, less any amounts
required to be withheld pursuant to applicable tax laws.

       (d) If any portion of the Merger Consideration or Option Consideration is
to be paid to a person other than the person in whose name a Certificate or
Option Agreement is registered, it shall be a condition to such payment that
such Certificate or Option Agreement shall be surrendered and shall be properly
endorsed or shall be otherwise 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 or instrument surrendered or shall have established to the
satisfaction of Acquiror and the Exchange Agent that such tax either has been
paid or is not payable.

       (e) At the Effective Time, the stock transfer books of the Company shall
be closed and there shall not be any further registration of transfers of Shares
thereafter on the records of the Company.

       (f) To the extent not immediately required for payment on surrendered
Shares and Options, proceeds in the Payment Fund shall be invested by the
Exchange Agent, as directed by the Surviving Corporation (as long as such
directions do not impair the rights of holders of Shares or Options), in direct
obligations of the United States of America, obligations for which the faith and
credit of the United States of America is pledged to provide for the payment of
principal and interest, commercial paper rated of the highest investment quality
by Moody's Investors Service, Inc. or Standard & Poor's Ratings Group, or
certificates of deposit issued by a commercial bank having at least $5 billion
in assets, and any net earnings with respect thereto shall be paid to the
Surviving Corporation as and when requested by the Surviving Corporation.

       (g) After the Effective Time, no dividends, interest or other
distributions shall be paid to the holder of any unsurrendered Certificates.

       (h) After the Effective Time, holders of Certificates shall cease to have
any rights as shareholders of the Company, except as provided herein or under
applicable state corporation law.  No 

                                      A-4
<PAGE>
 
interest shall be paid on any Merger Consideration or Option Consideration
payable to former holders of Shares or Options.

       (i) Promptly following the one-year anniversary date of the Effective
Date, the Exchange Agent shall return to the Surviving Corporation all of the
remaining Payment Fund, and the Exchange Agent's duties shall terminate.
Thereafter, each holder of a Certificate or an Option Agreement may surrender
the same to the Surviving Corporation and upon such surrender (subject to
applicable abandoned property, escheat or similar laws) shall receive the
applicable aggregate Merger Consideration and/or Option Consideration, as
applicable.  Notwithstanding the foregoing, neither the Exchange Agent nor any
party hereto shall be liable to any former holder of Shares or Options for any
amount delivered to a public official pursuant to applicable escheat or similar
law.

                                  ARTICLE II

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
                 ---------------------------------------------

       The Company represents and warrants to Acquiror that:

       Section 2.1.  Corporate Organization and Authorization.
                     ---------------------------------------- 

       (a) The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Minnesota and has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business, and to enter into this Agreement and to carry out the
transactions contemplated hereby.

       (b) (i) The Company has all requisite governmental authorizations,
   certificates, licenses, consents and approvals required to carry on its
   business as presently conducted, except where the failure to possess such
   authorizations, certificates, licenses, consents and approvals (either
   individually or in the aggregate) would not have a Material Adverse Effect on
   the Company (as defined in Section 2.1(b)(ii)).  The Company is duly
   qualified to do business as a foreign corporation and is in good standing in
   each jurisdiction where the character of the property owned or leased by it
   or the nature of the activities conducted by it makes such qualification
   necessary, except where the failure to so qualify or to maintain such good
   standing (either in one jurisdiction or in the aggregate) would not have a
   Material Adverse Effect.

           (ii) For purposes of this Agreement, "Material Adverse Effect" shall
   mean with respect to the Company or Acquiror, as applicable, any effect that
   individually or when taken together with all similar effects (i) is material
   and adverse to the prospects, assets, financial position, results of
   operations or business of the Company and the Subsidiary taken as a whole, or
   Acquiror and its subsidiaries taken as a whole, respectively, or (ii) would
   materially impair the ability of the Company or Acquiror, respectively, to
   perform its obligations under this Agreement or otherwise materially threaten
   or materially impede the consummation of the Merger and the other
   transactions contemplated by this Agreement; provided, however, that Material
   Adverse Effect shall not be deemed to include the impact of (a) actions or
   omissions of the Company or Acquiror taken with the prior written consent of
   the Company or Acquiror, as applicable, in contemplation of the transactions
   contemplated hereby, and (b) the effects of the Merger (or any announcement
   with respect thereto) and compliance with the provisions of this Agreement on
   the operating performance or prospects of such party and its subsidiaries,
   including without limitation, with respect to the Company, any loss of
   customer relationships or employees following the announcement of the Merger.

       (c) The Company's only subsidiary is Biomedical Equipment Rental & Sales,
Inc., (the "Subsidiary") and since 1992 the Company has not had any subsidiary
other than the Subsidiary.  For purposes of this section, "subsidiary" means any
entity of which securities or other ownership interests having ordinary voting
power to elect a majority of the Board of Directors or other persons performing
similar functions are directly or indirectly owned by the Company.  Neither the
Company nor the Subsidiary (i) directly or indirectly owns, (ii) has agreed to
purchase or otherwise acquire or (iii) holds any interest convertible into or
exchangeable or exercisable for, 5% or more of the capital stock or other 

                                      A-5
<PAGE>
 
equity interest of any corporation, partnership, company, joint venture or other
business association or entity (other than the Company's ownership of the
capital stock of the Subsidiary). Except as set forth in Schedule 2.1(c), and
for any agreements, arrangements or commitments solely between the Company and
the Subsidiary, there are no agreements, arrangements or commitments of any
character (contingent or otherwise) pursuant to which any person is or may be
entitled to receive any payment based on the revenues or earnings, or calculated
in accordance therewith, of the Company or the Subsidiary. There are no voting
trusts, proxies or other agreements or understandings to which the Company or
the Subsidiary is a party or by which the Company or the Subsidiary is bound
with respect to the voting of any shares of capital stock of the Company or the
Subsidiary.

       (d) The Subsidiary is a corporation duly organized, validly existing and
in good standing under the laws of North Carolina and has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business, and has all governmental authorizations, certificates,
licenses, consents and approvals required to carry on its business as presently
conducted, except where the failure to possess such authorizations,
certificates, licenses, consents and approvals (either individually or in the
aggregate) would not have a Material Adverse Effect on the Company.  The
Subsidiary is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction where the character of the property owned or
leased by it or the nature of the activities conducted by it makes such
qualification necessary, except where the failure to so qualify or to maintain
such good standing (either in one jurisdiction or in the aggregate) would not
have a Material Adverse Effect on the Company.

       (e) All of the outstanding capital stock of the Subsidiary (i) has been
validly issued, is fully paid and nonassessable and is not subject to preemptive
or similar rights and all such shares of capital stock were issued in material
compliance with all applicable federal and state securities laws, and (ii) is
owned by the Company free and clear of any lien or other encumbrance.  There are
no outstanding (i) securities of the Subsidiary convertible into or exchangeable
for shares of capital stock or other voting securities or ownership interests in
the Subsidiary or (ii) options or other rights to acquire from the Company or
the Subsidiary, and no other obligation of the Company or the Subsidiary to
issue, any capital stock, voting securities or other ownership interests in, or
any securities convertible into or exchangeable for, any capital stock, voting
securities or ownership interests in the Subsidiary (items in clauses (i) and
(ii) being referred to collectively as the "Subsidiary Securities").  There are
no outstanding obligations of the Company or the Subsidiary to repurchase,
redeem or otherwise acquire any outstanding Subsidiary Securities.

       (f) This Agreement has been duly authorized by the Board of Directors of
the Company, has been duly executed and delivered by the Company and, except for
obtaining the approval of the Company's shareholders at the Company Special
Meeting (as defined herein), no further corporate authorization on the part of
the Company is necessary to consummate the transactions contemplated by this
Agreement.

       (g) This Agreement constitutes a valid and binding agreement of the
Company and is enforceable against the Company in accordance with its terms,
except to the extent enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws relating to or affecting
creditors' rights generally and general equitable principles (whether considered
in a proceeding in equity or in law).

       (h) The copies of the respective Articles of Incorporation and Bylaws,
and all amendments thereto, of the Company and the Subsidiary heretofore
delivered to Acquiror are complete and true copies of such documents as in
effect on the date hereof.

       Section 2.2.  Capitalization.  The authorized capital stock of the
                     --------------                                      
Company consists of 10,000,000 shares of Common Stock, 100,000 shares of Series
A Junior Participating Preferred Stock, par value $.01 per share (the "Junior
Preferred Stock"), and 4,900,000 shares of undesignated preferred stock, par
value $.01 per share ("Undesignated Stock").  As of the date of this Agreement,
(a) 5,372,221 Shares were issued and outstanding, all of which have been duly
authorized, and are validly issued and outstanding, fully paid and
nonassessable; (b) no shares of Junior Preferred Stock were issued and
outstanding; (c) 540,867 Shares were reserved for issuance pursuant to
outstanding Options heretofore 

                                      A-6
<PAGE>
 
granted under the ISO Plan and the Directors' Plan. Schedule 2.2 sets forth as
of the date of this Agreement a schedule showing (i) each outstanding Option and
the date it was granted; (ii) the number of Shares subject thereto as of the
Effective Date (assuming full acceleration of vesting as provided in such
Options and Section 1.8); (iii) the exercise price; and (iv) the method by which
the number of Shares issuable pursuant to Section 1.8(b) under the ESPP may be
determined. All of the Shares were issued in material compliance with all
applicable federal and state securities laws and none of the Shares were issued
in violation of any preemptive or similar rights. Except as described in this
Section 2.2 (including shares reserved under the ESPP), no shares of the capital
stock of the Company are reserved for issuance for any purpose. Except as set
forth above or in the Rights Agreement, there are no other shares of capital
stock or other equity securities, instruments or other rights of the Company
outstanding and no other outstanding options, warrants, rights to subscribe to
(including any preemptive rights), calls or commitments of any character
whatsoever to which the Company or the Subsidiary is a party or may be bound
requiring the issuance, transfer or sale of any shares of capital stock or other
equity securities of the Company or any securities or rights convertible into or
exchangeable or exercisable for any such shares or equity securities, and there
are no contracts, commitments, understandings or arrangements by which the
Company or the Subsidiary is or may become bound to issue additional shares of
its capital stock options, warrants or rights to purchase, redeem or acquire any
additional shares of its capital stock or securities convertible into or
exchangeable or exercisable for any such shares or other securities.

       Section 2.3.  Noncontravention.
                     ---------------- 

       (a) Subject to the expiration or termination of the applicable waiting
period required by the HSR Act, neither the execution or delivery of this
Agreement nor the consummation of the transactions contemplated hereby:

           (i) violates, conflicts with, or constitutes a default under, the
   Articles of Incorporation or Bylaws, as amended, of any of the Company or the
   Subsidiary; or

           (ii) assuming that all consents, approvals, orders or authorizations
   contemplated by subsection (b) below have been obtained and all filings
   described therein have been made, (A) violates or will violate any statute or
   law or any rule, regulation, order, judgment or decree of any court or
   governmental authority to which the Company or the Subsidiary is subject or
   (B)(with or without notice or lapse of time or both), except as disclosed on
   Schedule 2.3(a) hereto, constitutes a default or breach under, or gives to
   others any rights of termination, acceleration or modification of, any note,
   bond, mortgage, indenture, deed of trust, license, lease or other material
   agreement, instrument or obligation to which the Company or the Subsidiary is
   a party or by which either of them is bound.

       (b) Except for the expiration or termination of the applicable waiting
period under the HSR Act, and in connection with the MBCA, the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), state securities or
"Blue Sky" laws or regulations (the "Blue Sky laws") and the Nasdaq Stock
Market, there is no other consent, approval, order or authorization of, or
filing with, or any permit from, or any notice to, any federal, governmental,
regulatory or administrative authority required to be obtained by the Company or
the Subsidiary for the execution of this Agreement by the Company and the
consummation of the transactions contemplated hereby.

       Section 2.4.  SEC Filings.
                     ----------- 

       (a) Prior to the execution of this Agreement, the Company has delivered
or made available to Acquiror complete and accurate copies of (i) the Company's

with the United States Securities and Exchange Commission (the "SEC"), (ii) all
Company proxy statements and annual reports to shareholders used in connection
with meetings of Company shareholders held since January 1, 1994 (the "Annual

Exchange Act with the SEC (such Company 10-K Reports, Annual Proxy Statements
and the Company 10-Q Report, together with all subsequent documents filed by the
Company with the SEC after December 

                                      A-7
<PAGE>
 
31, 1996 and prior to the Effective Date, are referred to herein as the "Company
Public Reports"), and (iv) the Company's unaudited financial statements for the
year ended December 31, 1996 (the "Interim Financial Statements"). As of their
respective dates, the Company Public Reports (x) did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading and (y) complied as to
form in all material respects with the applicable laws and rules and regulations
of the SEC. Since January 1, 1993, the Company has filed in a timely manner all
reports that it was required to file with the SEC pursuant to the Exchange Act.

       (b) The Company financial statements (including any footnotes thereto)
contained in the Company Public Reports and the Interim Financial Statements
were prepared in accordance with the published rules and regulations of the SEC
and generally accepted accounting principles applied on a consistent basis
during the periods involved (except as may be otherwise indicated therein and
except that the Interim Financial Statements do not contain any footnotes
thereto) and fairly presented the consolidated financial position of the Company
and the Subsidiary as of the dates thereof and the consolidated results of
operations, changes in shareholders' equity and cash flows for the periods then
ended, except that any unaudited financial statements contained therein are
subject to normal and recurring year-end adjustments.

       Section 2.5.  No Material Adverse Changes.  Since December 31, 1996,
                     ---------------------------                           
there has been no material adverse change in, and no event, loss, occurrence or
development in the business of the Company or the Subsidiary, taken as a whole,
that, taken together with other events, occurrences and developments with
respect to such business, has had or would reasonably be expected to have a
Material Adverse Effect on the Company.  Except as disclosed in the Company
Public Reports filed prior to the date of this Agreement or as contemplated in
this Agreement, since December 31, 1996, the Company and the Subsidiary have
conducted their respective businesses only in the ordinary course and in a
manner consistent with past practice.

       Section 2.6.  Legal Proceedings.  Except as set forth on Schedule 2.6
                     -----------------                                      
attached hereto, there are no, and since January 1, 1995 there have not been
any, claims, actions, suits, proceedings (arbitration or otherwise) or
investigations pending or, to the Company's knowledge, threatened by or against,
the Company or the Subsidiary.   Except as set forth on Schedule 2.6, no such
claims, actions, suits, proceedings or investigations are (i) seeking to enjoin,
prohibit, restrain or otherwise prevent the transactions contemplated hereby or
(ii) reasonably likely to result in a Material Adverse Effect on the Company if
adversely determined.  There are no judgments, decrees or orders issued by any
court, board or other governmental or administrative agency presently
outstanding and unsatisfied against the Company or the Subsidiary.

       Section 2.7.  No Dividends or Distributions.  Since December 31, 1996,
                     -----------------------------                           
there has not been any declaration, setting aside or payment of any dividend or
any other distribution with respect to the Company's or the Subsidiary's capital
stock or any redemption, purchase or other acquisition of any of the Company's
securities.

       Section 2.8.  Fairness Opinion.  The Board of Directors of the Company
                     ----------------                                        
has received the written opinion of Piper Jaffray Inc., financial advisor to the
duly appointed and acting special committee of the Board of Directors of the
Company (the "Special Committee"), dated as of the date hereof to the effect
that the consideration to be received by the Company's shareholders in the
Merger is fair to the shareholders of the Company from a financial point of
view, and such opinion is in a form and substance reasonably satisfactory to the
Special Committee.

       Section 2.9.  Tax Matters.
                     ----------- 

       (a) Each of the Company and the Subsidiary has filed all Tax Returns
required to be filed by any of them on or prior to the Effective Date and has
paid (or the Company has paid on its behalf), or has set up an adequate reserve
for the payment of, all Taxes required to be paid in respect of the periods
covered by such returns (except where the failure to pay would not have a
Material Adverse Effect on the Company).  The information contained in such Tax
Returns is true, complete and accurate in all material 

                                      A-8
<PAGE>
 
respects. Neither the Company nor the Subsidiary is delinquent in the payment of
any tax, assessment or governmental charge, except where such delinquency would
not have a Material Adverse Effect on the Company. There are no Tax liens upon
the assets of the Company or the Subsidiary except liens for Taxes not yet due
or being contested in good faith through appropriate proceedings. No deficiency
for any Taxes has been proposed, asserted or assessed against the Company or the
Subsidiary that has not been resolved or paid in full. No audits or other
administrative proceedings or court proceedings are presently pending with
regard to any material Taxes or Tax Returns of the Company or the Subsidiary. No
amount that could be received (whether in cash or property or the vesting of
property) as a result of any of the transactions contemplated by this Agreement
by any employee, officer or director of the Company or any of its affiliates who
is a "disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or company benefit plan currently in

Company or the Subsidiary to undertake, or to bear all or any portion of the
cost of any Cleanup which, in the case of clauses (A) or (B), could have a
Material Adverse Effect on the Company.

                                   ---------

       Section 4.1.  Conduct of the Company Prior to the Effective Time.
                     -------------------------------------------------- 

       (a) No Solicitation; Other Offers.
           ----------------------------- 

           (i) From the date hereof until the termination of this Agreement or
   the Effective Date, whichever first occurs, the Company will not, and will
   cause the Subsidiary not to, and will use its best efforts to cause the
   officers, directors, employees, representatives and agents of the Company and
   the Subsidiary not to, directly or indirectly, solicit, initiate or encourage
   any inquiry, proposal, offer or indication of interest from any person that
   constitutes or would reasonably be expected to lead to any Acquisition
   Proposal (as hereinafter defined) or enter into discussions or negotiate with
   any person or entity in furtherance of any such inquiries or to obtain or
   approve any Acquisition Proposal, or agree to or endorse any Acquisition
   Proposal, and the Company shall immediately notify Acquiror of all relevant
   terms  of any such inquiries or proposals received by the Company or the
   Subsidiary or by any such officer, director, employee, representatives, or
   agents, relating to any of such matters, any material change in the details
   (including any amendments or proposed amendments) of any such inquiries or
   proposals, the identity of each of the persons or entities making such
   inquiries or proposals, and, if such inquiry or proposal is in writing, the
   Company shall immediately deliver or cause to be delivered to Acquiror a copy
   of such inquiry or proposal; provided, however, that if, prior to the
                                --------  -------                       
   Effective Time, the Company shall receive an unsolicited Acquisition Proposal
   that the Board of Directors of the Company, based upon the advice of its
   legal counsel, reasonably believes that it has a fiduciary duty to consider,
   then the Company, without violating this Agreement, may thereafter furnish
   information to and enter into discussions or negotiations with such third
   party.  Nothing contained in this Section 4.1(a) or any other provision of
   this Agreement shall prevent the Board of Directors of the Company or the
   Special Committee, after receiving an opinion of outside counsel to the
   effect that the Board of Directors is required to do so in order to discharge
   properly its fiduciary duties, from considering, negotiating, approving and
   recommending to the shareholders of the Company an unsolicited, bona fide
   written Acquisition Proposal which the Board of Directors of the Company
   determines in good faith (after consultation with its financial advisors) (A)
   would result in a transaction more favorable to the Company's shareholders
   than the transaction contemplated by this Agreement and (B) is made by a
   person financially capable of consummating such Acquisition Proposal (any
   such Acquisition Proposal being referred to herein as a "Superior Proposal").
   If the Board of Directors of the Company shall have resolved to accept or
   accepted a Superior Proposal then upon written notice to Acquiror, the
   Company may pursuant to Section 8.1(d) terminate this Agreement and the
   transactions contemplated hereby.  For purposes hereof, "Acquisition
   Proposal" means any proposal for a merger, consolidation or other business
   combination involving the Company or the acquisition of any equity interest
   in, or a substantial portion of the assets of the Company or the Subsidiary,
   other than the transactions contemplated by this Agreement.

   by Section 4.1(a)(i), the Company shall pay to Acquiror the sum of $3,000,000

   deemed to include all costs and expenses of Acquiror.

   division thereof, or otherwise acquire or agree to acquire any assets of any
   other person (other than the purchase or lease of assets from suppliers or
   vendors in the ordinary course of business consistent with past practice); or
   (E) enter into any contract, agreement, commitment or arrangement with
   respect to any of the foregoing;

           (iv) Except as disclosed on Schedule 4.1(b), the Company shall not,

   director, officer or current or former employee; (B) increase in any manner
   the compensation or fringe benefit of any director, officer or employee

   consistent with past practice and that, in the aggregate, do not result in a
   material increase in such employee's benefits or compensation relative to the
   level in effect prior to such amendment); (C) pay any benefit not

       (a) Employee Benefits.  As of the Effective Time, the employees of the
           -----------------                                                 
Company and the Subsidiary (the "Company Employees") shall continue employment
with the Surviving Corporation and its subsidiaries, respectively, in the same
positions and at the same level of wages and/or salary and without having
incurred a termination of employment or separation from service; provided,

Time shall be credited in determining such employee's eligibility, vesting and
benefit levels (but not for accrual of benefits), and (ii) with respect to any
welfare benefit plans to which such employees may become eligible, Acquiror
shall cause such plans to provide credit for any co-payments or deductibles by

Employees prior to the Effective Time.

termination of this Agreement, each party will hold, and will use its best
efforts to cause its officers, directors, employees,

accountants, counsel, consultants, advisors and agents to hold, in confidence,
unless compelled to disclose by judicial or administrative process or by other
requirements of law, all confidential documents and information concerning the
other party furnished in connection with the transactions contemplated by this
Agreement, except to the extent that such information can be shown to have been
(i) previously known on a nonconfidential basis by such party (ii) in the public
domain through no fault of such party or (iii) later lawfully acquired by such
party from sources other than the other party; provided that such party may
                                               --------

counsel, consultants, advisors and agents in connection with the transactions
contemplated by this Agreement and, in the case of Acquiror, to its lenders in
connection with obtaining the financing for the transactions contemplated by
this Agreement so long as such persons are informed by such party of the
confidential nature of such information and are directed by such party to treat
such information confidentially. Each party's obligation to hold any such
information in confidence shall be satisfied if it exercises the same care with
respect to such information as it would take to preserve the confidentiality of
its own similar information. If this Agreement is terminated, each party will,
and will cause its subsidiaries, to use its best efforts to cause their
respective officers, directors, employees, accountants, counsel, consultants,
advisors and agents to, destroy or deliver to the other party, upon request, all
documents and other materials, and all copies thereof, obtained by such party or
on its behalf from the other party in connection with this Agreement that are
subject to such confidence.

Company or the Subsidiary at any time prior to the Effective Date which are

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

maintain in effect for not less than six years after the Effective Date, the
