        Payment shall equal (i) THREE HUNDRED THOUSAND DOLLARS ($300,000), in

        DOLLARS ($800,000), in the event the BMC Business' Pre-Tax Earnings for

        Payment shall be due or payable in the event the BMC Business' Pre-Tax
        Earnings for the Contingent Payment Period is less than $600,000.

                2.1.(c) Calculation of Pre-Tax Earnings. The calculation of the
        BMC Business' Pre-Tax Earnings for the Contingent Payment Period shall
        include revenue received from retirement plan administration and
        consulting services but shall not include revenue received from COBRA
        administration services or other services not performed by Company as of
        the date hereof but offered by Buyer or any of its subsidiaries or
        affiliates. Except as expressly provided herein, the calculation of
        Pre-Tax Earnings shall be made in accordance with generally accepted
        accounting principles applied on a consistent basis, subject to the
        following adjustments:

                     (i)  Any depreciation or amortization adjustments resulting
                solely from the transactions contemplated by this Agreement
                shall not be included for purposes of calculating Pre-Tax
                Earnings for the Contingent Payment Period.

                     (ii) Notwithstanding Company's actual expenses for the
                Contingent Payment Period relating to items and functions (such
                as property and casualty insurance, errors and omissions
                insurance, health and welfare programs and human resource
                functions) that Company and Buyer mutually agree shall be
                provided by Buyer or another subsidiary thereof, Company shall
                accrue as an expense for purposes of calculating Pre-Tax
                Earnings for the Contingent Payment Period the same dollar
                amount as it accrued in the twelve months preceding the
                Effective Date with respect to such items and functions.

<PAGE>   8

                     (iii) The calculation of Pre-Tax Earnings for the
                Contingent Payment Period shall not exclude any expense item (or
                series of related items) relating to personnel matters or
                exceeding $10,000 annually, unless such exclusion has been
                preapproved in writing by Buyer. The parties hereby agree that
                the calculation of Pre-Tax Earnings shall exclude legal and
                accounting fees associated with the transaction contemplated
                hereby because the Closing Balance Sheet (as defined in Section
                3.4) reflects all such accrued costs or such costs will be paid
                by the Principal Shareholder in accordance with the Section 10.8
                hereof. Additionally, such costs (other than those paid directly
                by the Principal Shareholder), excluding the first $25,000
                (which Buyer has agreed to pay), will be included in the minimum
                net worth and minimum working capital calculations contemplated
                in Section 3.4 hereof.

                     (iv) Company shall review with Buyer on a monthly basis any
                and all expense items Company intends to exclude for purposes of
                calculating Pre-Tax Earnings for the Contingent Payment Period.

                     (v)  In the event Buyer (or any subsidiary thereof)
                generates new retirement plan administration or consulting
                services business for Company during the Contingent Payment
                Period, and/or Company generates new COBRA or pension
                administration services business (or other new business for
                similar administrative services not performed by Company as of
                the date hereof), Buyer and Company agree to make a reasonable
                allocation of sales and other reasonable costs associated with
                obtaining such new business for purposes of calculating
                Company's Pre-Tax Earnings for the Contingent Payment Period.

                2.1.(d) Conduct of Business During the Contingent Payment
        Period. During the Contingent Payment Period, Buyer covenants and agrees
        that Buyer will, and if appropriate will cause its Affiliates to, (i)
        not move the business location of Company more than 30 miles from the
        business premises of the BMC Business as of the date hereof, and (ii)
        permit the Principal Shareholder (subject to his employment agreement
        with Company) to manage and control the day-to-day affairs of the BMC
        Business.

        2.2. Payment of Purchase Price. The Purchase Price shall be paid by
Buyer as follows:

                2.2.(a) Cash to Shareholders' Agent. At the Closing, Buyer shall
        deliver to the Shareholders' Agent the sum of One Million Seven Hundred
        Forty-Five Thousand Dollars ($1,745,000). Additionally, Buyer shall
        deliver to the Company the sum of Three Hundred Seventy-Five Thousand
        Dollars ($375,000), which amount shall constitute payment in full of
        that certain

                                       3
<PAGE>   9

        Promissory Note, dated October 29, 1998, of the Principal Shareholder in
        favor of the Company in the principal amount of $375,000.

                2.2.(b) Contingent Payment. The initial calculation of the
        Contingent Payment shall  be made by Buyer, which shall deliver its
        calculation (setting forth in reasonable detail Buyer's calculation of
        the BMC Business' Pre-Tax Earnings and the various elements thereof) on
        or before January 31, 2000 to Shareholders' Agent for his review and
        comment. If Buyer and Shareholder's Agent are able to agree in writing
        upon the amount of the Contingent Payment within fifteen (15) days
        following delivery of the initial calculation to Shareholders' Agent,
        then Buyer shall pay such amount. Such payment of the Contingent
        Payment, if any, shall be made to the Shareholders' Agent within fifteen
        (15) days following the date of such written agreement but in no event
        earlier than January 1, 2000. In the event Buyer and Shareholders' Agent
        cannot agree on the amount of the Contingent Payment by March 1, 2000,
        then the determination of the Contingent Payment shall be submitted to
        binding arbitration in accordance with Article 9 of this Agreement and
        shall be paid on the later of (i) January 2, 2000, or (ii) 5 days after
        a determination pursuant to such arbitration procedures.

                2.2.(c) Purchase Price Holdback for Securing Minimum Net Worth
        and Minimum Working Capital Requirements in the Closing Balance Sheet.
        On the Closing Date, Buyer will transfer the sum of Three Hundred Eighty
        Thousand Dollars ($380,000) to a segregated interest-bearing account
        with a bank or other financial institution with a combined capital and
        surplus in excess of $50,000,000, which amount shall be held by Buyer in
        such account for the purpose of securing the representation contained in
        Section 3.4 hereof that the Closing Balance Sheet (as defined in Section
        3.4) will, upon finalization following receipt of the Recent Balance
        Sheet, reflect that the Company had a net worth (i.e., stockholders'
        equity) of at least $380,000 and working capital (i.e., current assets
        less current liabilities) of at least $130,000 as of October 31, 1998.
        If the Closing Balance Sheet, upon finalization, does not reflect that
        the Company had a net worth of at least $380,000 or working capital of
        at least $130,000 as of October 31, 1998, then Buyer shall deliver to
        Principal Shareholder that portion of the funds held in the segregated
        account equal to (x) $380,000, less the greater of (y) the amount by
        which the net worth as reflected on the Closing Balance Sheet falls
        below $380,000, or (z) the amount by which the working capital as
        reflected on the Closing Balance Sheet falls below $130,000. If the
        Closing Balance Sheet, upon finalization, reflects that the Company had
        a net worth of at least $380,000 and working capital of at least
        $130,000 as of October 31, 1998, then Buyer shall deliver to Principal
        Shareholder the entire $380,000 held in the segregated account. Buyer
        shall deliver the requisite amount to the Principal Shareholder promptly
        after receipt of the Recent Balance Sheet and finalization of the

                2.2.(d) Purchase Price Holdback for Securing the General
        Indemnification Obligations of Company and the Principal Shareholder.

                     (i)  On the Closing Date, Buyer will transfer the sum of
                Five Hundred Thousand Dollars ($500,000) to a segregated
                interest-bearing account with a bank or other financial
                institution with a combined capital and surplus in excess of
                $50,000,000, which amount shall be held by Buyer in such account
                for the purpose of securing the indemnification obligations of
                Company and the Principal Shareholder under this Agreement. For
                purposes hereof, "Holdback Period" shall mean the period
                commencing on the date hereof and ending five (5) months from
                the Closing Date, subject to extension as hereinafter provided.

                     (ii) If, prior to the expiration of the Holdback Period,
                Buyer determines to assert a claim for indemnification under
                Article 6 of this Agreement, then Buyer shall give the Principal
                Shareholder written notice of such claim (for purposes of this
                Section 2.2(c), a "Claim Notice"), specifying in reasonable
                detail the basis therefor and the amount and calculation
                thereof. If the Principal Shareholder does not deliver to Buyer
                written notice of an objection to the claim for indemnification
                within twenty (20) days after receipt of the Claim Notice
                relating thereto, Buyer shall be entitled to withdraw the dollar
                amount of its claim (as set forth in the Claim Notice) from the
                segregated account. If the Principal Shareholder shall timely
                deliver to Buyer such written notice of objection, then Buyer
                shall not make a withdrawal from the segregated account with
                respect to the claim set forth in the Claim Notice until: (x)
                Buyer and Principal Shareholder have executed joint written
                instructions referring to such Claim Notice and directing Buyer
                to withdraw, for Buyer's own account, funds from the segregated
                account; or (y) Buyer has received a copy of a judgment, decree
                or order of a court, or copy of an arbitration award,
                adjudicating the dispute and determining an amount with respect
                to such claim for indemnification; whereupon Buyer shall
                withdraw from the segregated account, for Buyer's own account,
                such amount as provided therein.

                     (iii) If Buyer has not delivered a Claim Notice to
                Principal Shareholder prior to the expiration of the Holdback
                Period, or if any and all Claim Notices delivered to Principal
                Shareholder during the Holdback Period have been resolved
                pursuant to subsection (ii) above, then Buyer shall deliver to
                Principal Shareholder the portion of the funds held in the
                segregated account equal to (x) $500,000, less (y) any amounts
                withdrawn by Buyer as provided herein, plus (z) any interest
                earned with respect to such balance. Buyer shall deliver such
                amount to the Principal Shareholder promptly after the
                expiration of the Holdback Period, unless one or more Claim
                Notice(s) have not been finally resolved pursuant to 

                                       5
 
<PAGE>   11


                subsection (ii) above, in which case Buyer shall retain such
                amount in the segregated account until: (a) Buyer and Principal
                Shareholder have executed joint written instructions referring
                to such Claim Notice(s) and directing Buyer as to the
                disbursement of the funds in the segregated account; or (b)
                Buyer has received a copy of a judgment, decree or order of a
                court, or copy of an arbitration award, adjudicating the dispute
                and determining an amount with respect to such Claim Notice(s);
                whereupon Buyer shall disburse the funds in the segregated
                account as provided therein.

                2.2.(e) Method of Payment. All payments under this Section 2.2
        shall be made in the form of certified or bank cashier's check payable
        to the order of the recipient or, at the recipient's option, by wire
        transfer of immediately available funds to an account designated by the
        recipient not less than 48 hours prior to the time for payment specified
        herein.

<PAGE>   14

books and records of Company, and fairly present, in accordance with
generally accepted accounting principles, the assets, liabilities and financial
position, the results of operations and cash flows of Company as of the dates

Sheet will, upon receipt, reflect that the Company had a net worth (i.e.,
stockholders' equity) of at least $380,000 and working capital (i.e., current
assets less current liabilities) of at least $130,000 as of October 31, 1998.

     3.5.     Tax Matters.

          3.5.(a)  Provision For Taxes. The provision made for taxes on the
     Closing Balance Sheet is sufficient for the payment, either currently or on
     a deferred basis, of all federal, state, foreign, county, local and other
     income, ad valorem, excise, profits, franchise, occupation, property,
     payroll, sales, use, gross receipts and other taxes (and any interest and
     penalties) and assessments, whether or not disputed, at the date of the
     Closing Balance Sheet and for all years and periods prior thereto. Since
     the date of the Recent Balance Sheet, Company has not incurred any taxes
     other than taxes incurred in the ordinary course of business consistent in
     type and amount with past practices of Company.

          3.5.(b)  Tax Returns Filed. Except as set forth on Schedule 3.5.(b),
     all federal, state, foreign, county, local and other tax returns required
     to be filed by or on behalf of Company have been timely filed and when
     filed were true and correct in all material respects, and the taxes shown
     as due thereon were paid or adequately accrued. True and complete copies of
     all tax returns or reports filed by Company for each of its three most
     recent fiscal years have been delivered to Buyer. Company has duly withheld
     and paid all taxes which it is required to withhold and pay relating to
     salaries and other compensation heretofore paid to the employees of
     Company.

          3.5.(c)  Tax Audits. The federal and state income tax returns of
     Company have not been audited by the Internal Revenue Service or any state
     taxing authorities for any period, and Company has not received from the
     Internal Revenue Service or from the tax authorities of any state, county,
     local or other jurisdiction any notice of underpayment of taxes or other
     deficiency which has not been paid nor any objection to any return or
     report filed by Company. There are outstanding no agreements or waivers
     extending the statutory period of limitations applicable to any tax return
     or report.

          3.5.(d)  No Consolidated Group. Company has never been a member of an
     affiliated group of corporations that filed a consolidated tax return.
     Company does not have any liability for the taxes of any person or entity
     under Sections 1.1502-6 or 1.1502-78 of Title 26 of the Code of Federal 




                                       9
<PAGE>   15
     Regulations (or any similar provisions of state, local or foreign income
     tax laws).

          3.5.(e)  S Corporation. Company properly and timely filed a valid
     election under Section 1362 of the Internal Revenue Code of 1986, as
     amended (the "Code"), to be treated as an S corporation ("S Corp") as
     defined under Section 1361 of the Code for federal income tax purposes
     effective from January 1, 1991 and has corresponding elections in effect
     under the laws of Colorado. Such elections have remained in effect since
     January 1, 1991. Except for transactions contemplated by this Agreement,
     neither Company nor any of the Shareholders has taken any action, nor has
     any event occurred, that would result in the revocation or termination of
     any of such elections. Company is not subject to the tax imposed by Section
     1374 of the Code (or any equivalent state statute) and Company does not
     have a "net unrealized built-in gain" as such phrase is defined in Section
     1374(d) of the Code (or any equivalent state statute).

          3.5.(f)  Other. Except as set forth in Schedule 3.5.(f), Company has
     not (i) filed any consent or agreement under Section 341(f) of the Internal
     Revenue Code of 1986, as amended (the "Code"), (ii) applied for any tax
     ruling, (iii) entered into a closing agreement with any taxing authority,
     (iv) filed an election under Section 338(g) or Section 338(h)(10) of the
     Code (nor has a deemed election under Section 338(e) of the Code occurred),
     except as contemplated hereby, (v) made any payments, or been a party to an
     agreement (including this Agreement) that under any circumstances could
     obligate it to make payments that will not be deductible because of Section
     280G of the Code, or (vi) been a party to any tax allocation or tax sharing
     agreement. The Company is not a "United States real property holding
     company" within the meaning of Section 897 of the Code.

     3.6.  Accounts Receivable. All accounts receivable of Company reflected on
the Closing Balance Sheet, and all accounts receivable incurred in the normal
course of business since the date thereof, represent arm's length sales actually
made in the ordinary course of business; are collectible (net of the reserve
shown on the Closing Balance Sheet for doubtful accounts) in the ordinary course
of business without the necessity of commencing legal proceedings; are subject
to no counterclaim or setoff; and are not in dispute. Schedule 3.6 contains an
aged schedule of accounts receivable included in the Closing Balance Sheet.

practice and none of which has or will have a material adverse effect on the
business, financial condition or results of operations of Company. Except as and
to the extent described in the Recent Balance Sheet or in Schedule 3.8, neither
Company nor any Shareholder has knowledge of any basis for the assertion against
Company of any liability and there are no circumstances, conditions, happenings,
events or arrangements, contractual or otherwise, which may give rise to

ordinary course of Company's business and consistent with past practice.

     foregoing:

               (i)  To the knowledge of the Shareholders, the operation of
          Company's business as it is now conducted does not, nor does any
          condition existing at any of the Facilities, in any manner constitute
          a nuisance or other tortious interference with the rights of any
          person or persons in such a manner as to give rise to or constitute
          the grounds for a suit, action, claim or demand by any such person or
          persons seeking compensation or damages or seeking to restrain, enjoin
          or otherwise prohibit any aspect of the conduct of such business or
          the manner in which it is now conducted.

               (ii)  Company has made all required payments to its unemployment
          compensation reserve accounts with the appropriate governmental
          departments of the states where it is required to maintain such
          accounts, and each of such accounts has a positive balance.

               (iii)  Company has delivered to Buyer copies of all reports of
          Company for the past five (5) years required under the federal
          Occupational Safety and Health Act of 1970, as amended, and under all
          other applicable health and safety laws and regulations. The
          deficiencies, if any, noted on such reports have been corrected.

          3.10.(b)  Licenses and Permits. Company has all licenses, permits,
     approvals, authorizations and consents of all Government Entities and all
     certification organizations required for the conduct of the business (as

     Facilities. All such licenses, permits, approvals, authorizations and
     consents are described in Schedule 3.10.(b), are in full force and effect

     obligation to reapply as a result of the transactions contemplated hereby.
     Except as set forth in Schedule 3.10.(b), Company (including its
     operations, properties and assets) is and has been in compliance with all
     such permits and licenses, approvals, authorizations and consents.

          3.10.(c)  Environmental Matters. The applicable Laws relating to
     pollution or protection of the environment, including Laws relating to
     emissions, discharges, generation, storage, releases or threatened releases

     provisions of this Section 3.10, Company is in full compliance with all
     material limitations, restrictions, conditions, standards, prohibitions,
     requirements, obligations, schedules and timetables contained in the
     Environmental Laws or contained in any regulations, code, plan, order,
     decree, judgment, injunction, notice or demand letter issued, entered,
     promulgated or approved thereunder. Except as set forth in Schedule
     3.10.(c), there is no Litigation nor any demand, claim, hearing or notice
     of violation pending or, to the knowledge of the Shareholders, threatened
     against Company relating in any way to the Environmental Laws or any Order
     issued, entered, promulgated or approved thereunder. Except as set forth in
     Schedule 3.10.(c), there are no past or present (or, to the best of

     circumstances, activities, practices, incidents, actions, omissions or
     plans which may interfere with or prevent compliance or continued
     compliance with the Environmental Laws or with any Order issued, entered,
     promulgated or approved thereunder, or which may give rise to any
     liability, including, without limitation, liability under CERCLA or similar
     state or local Laws, or otherwise form the basis of any Litigation,
     hearing, notice of violation, study or investigation, based on or related
     to the manufacture, processing, distribution, use, treatment, storage,
     disposal, transport or handling, or the emission, discharge, release or
     threatened release into the environment, of any Waste.

     3.11.    Title to and Condition of Properties.

          3.11.(a)  Marketable Title. Company has good and marketable title to
     all of Company's assets, business and properties, including, without
     limitation, all such properties (tangible and intangible) reflected in the
     Recent Balance Sheet, free and clear of all mortgages, liens, (statutory or
     otherwise) security interests, claims, pledges, licenses, equities,
     options, conditional sales contracts, assessments, levies, easements,
     covenants, reservations, restrictions, rights-of-way, exceptions,
     limitations, charges or encumbrances of any nature whatsoever
     (collectively, "Liens") except those described in Schedule 3.11(a) and, in
     the case of real property, Liens for taxes not yet due or which are being
     contested in good faith by appropriate proceedings (and which have been
     sufficiently accrued or reserved against in the Recent Balance Sheet),
     municipal and zoning ordinances and easements for public utilities, none of
     which interfere with the use of the property as currently utilized. None of
     Company's assets, business or properties are subject to any restrictions
     with respect to the 



                                       14
<PAGE>   20
     transferability thereof; and the Company's title thereto will not be
     affected in any way by the transactions contemplated hereby.

          3.11.(b)  Condition. All property and assets owned or utilized by
     Company are in good operating condition and repair, free from any defects
     (except such minor defects as do not interfere with the use thereof in the
     conduct of the normal operations of Company), have been maintained
     consistent with the standards generally followed in the industry and are
     sufficient to carry on the business of Company as conducted during the
     preceding 12 months. To the knowledge of the Shareholders, all buildings,
     plants and other structures owned or otherwise utilized by Company are in
     good condition and repair and have no material structural defects or
     defects affecting the plumbing, electrical, sewerage, or heating,
     ventilating or air conditioning systems.

          3.11.(c)  Real Property. Company does not own any real property. The
     only real property used or occupied by Company (the "Real Property") is
     leased from an unaffiliated third-party lessor, and Schedule 3.11.(c) sets
     forth, the material terms of such lease. To the knowledge of the Principal
     Shareholder, there are now in full force and effect duly issued
     certificates of occupancy permitting the Real Property and improvements
     located thereon to be legally used and occupied as the same are now
     constituted. To the knowledge of the Principal Shareholder, all of the Real
     Property has permanent rights of access to dedicated public roads. To the
     knowledge of the Principal Shareholder, no fact or condition exists which
     would prohibit or adversely affect the ordinary rights of access to and
     from the Real Property from and to the existing roads and there is no
     pending or threatened restriction or denial, governmental or otherwise,
     upon such ingress and egress. To the knowledge of the Principal Shareholder
     there is not (i) any claim of adverse possession or prescriptive rights
     involving any of the Real Property, (ii) any structure located on any Real
     Property which encroaches on or over the boundaries of neighboring or
     adjacent properties or (iii) any structure of any other party which
     encroaches on or over the boundaries of any of such Real Property. To the
     knowledge of the Principal Shareholder, none of the Real Property is
     located in a flood plain, flood hazard area, wetland or lakeshore erosion
     area within the meaning of any Law, regulation or ordinance. To the
     knowledge of the Principal Shareholder, no public improvements have been
     commenced and to Company's and Shareholders' knowledge none are planned
     which in either case may result in special assessments against or otherwise
     materially adversely affect any Real Property. To the knowledge of the
     Principal Shareholder, no portion of any of the Real Property has been used
     as a landfill or for storage or landfill of hazardous or toxic materials.
     The Principal Shareholder has no knowledge of any (i) planned or proposed
     increase in assessed valuations of any Real Property, (ii) Order requiring
     repair, alteration, or correction of any existing condition affecting any
     Real Property or the systems or improvements thereat, (iii) condition or
     defect which could give rise to an order of the sort 



                                       15
<PAGE>   21
     referred to in "(ii)" above, (iv) underground storage tanks, or any
     structural, mechanical, or other defects of material significance affecting
     any Real Property or the systems or improvements thereat (including, but
     not limited to, inadequacy for normal use of mechanical systems or disposal
     or water systems at or serving the Real Property), or (v) work that has
     been done or labor or materials that has or have been furnished to any Real
     Property during the period of six (6) months immediately preceding the date
     of this Agreement for which liens could be filed against any of the Real
     Property.

          3.11.(d)  No Condemnation or Expropriation. To the knowledge of the
     Shareholders, neither the whole nor any portion of the property or any
     other assets of Company is subject to any Order to be sold or is being
     condemned, expropriated or otherwise taken by any Government Entity with or
     without payment of compensation therefor, nor has any such condemnation,
     expropriation or taking been proposed.

     3.12.  Insurance. Set forth in Schedule 3.12 is a complete and accurate
list and description of all policies of fire, liability, errors and omissions,
electronic data processing, workers compensation, health and other forms of
insurance presently in effect with respect to the business and properties of
Company, true and correct copies of which have heretofore been delivered to
Buyer. Schedule 3.12 includes, without limitation, the carrier, the description
of coverage, the limits of coverage, retention or deductible amounts, amount of
annual premiums, retroactive date of coverage, date of expiration and the date
through which premiums have been paid with respect to each such policy, and any
pending claims in excess of $5,000. All such policies are valid, outstanding and
enforceable policies and provide insurance coverage for the properties, assets
and operations of Company, of the kinds, in the amounts and against the risks
customarily maintained by organizations similarly situated; and no such policy
(nor any previous policy) provides for or is subject to any currently
enforceable retroactive rate or premium adjustment, loss sharing arrangement or
other actual or contingent liability arising wholly or partially out of events
arising prior to the date hereof. Schedule 3.12 indicates each policy as to
which (a) the coverage limit has been reached or (b) the total incurred losses
to date equal 75% or more of the coverage limit. No notice of cancellation or
termination has been received with respect to any such policy, and neither
Company nor any Shareholder has knowledge of any act or omission of Company
which could result in cancellation of any such policy prior to its scheduled
expiration date. Company has not been refused any insurance with respect to any
aspect of the operations of the business nor has its coverage been limited by
any insurance carrier to which it has applied for insurance or with which it has
carried insurance during the last three years. Company has duly and timely made
all claims it has been entitled to make under each policy of insurance. There is
no claim by Company pending under any such policies as to which coverage has
been questioned, denied or disputed by the underwriters of such policies, and
neither Company nor any of the Shareholders knows of any basis for denial of any
claim under any such policy. Company has not received any written notice from or
on behalf of any insurance carrier issuing any such policy that insurance rates
therefor will hereafter be substantially increased (except to the extent that
insurance rates may be increased for all similarly situated risks) or that there
will hereafter be a cancellation or an



                                       16

increase in a deductible (or an increase in premiums in order to maintain an
existing deductible) or nonrenewal of any such policy.  Such policies are
sufficient in all material respects for compliance by Company with all
requirements of law and with the requirements of all material contracts to
which Company is a party.  Except as set forth on Schedule 3.12, all
general liability policies maintained by or for the benefit of Company since
its inception have been "occurrence" policies and not "claims made" policies.

            no sales contracts or commitments except those made in the ordinary
            course of business, at arm's length, and no such contracts or
            commitments are for a sales price which would result in a loss to
            the Company.

                 3.13.(e) Contracts With Affiliates and Certain Others.

            instrument which is so burdensome as to materially affect or impair
            the operation of Company.  Without limiting the generality of the
            foregoing, Company is not a party to nor is it bound by any
            agreement requiring Company to assign any interest in any trade
            secret or proprietary information, or prohibiting or restricting
            Company from competing in any business or geographical area or
            soliciting customers or otherwise restricting it from carrying on
            its business anywhere in the world.

            creation of any Lien on any of the assets owned, used or occupied
            by Company.  To the knowledge of the Shareholders, no third party
            is in default under any lease, contract or commitment to which
            Company is a party, nor has any event or omission occurred which,
            through the passage of time or the giving of notice, or both, would
            constitute a default thereunder or give rise to an automatic
            termination, or the right of discretionary termination, thereof.

            Section 3(3) of the Employee Retirement Income Security Act of
            1974, as amended ("ERISA")), all employee manuals, and all written
            or binding oral statements of policies, practices or understandings
            relating to employment, which are provided to, for the benefit of,
            or relate to, any persons ("Company Employees") employed by
            Company.  The items described in the foregoing sentence are
            hereinafter sometimes referred to collectively as "Employee
            Plans/Agreements," and each individually as an "Employee

            Plans/Agreements, including all amendments thereto, have heretofore
            been provided to Buyer.  Each of the Employee Plans/Agreements is

            obligated to contribute to any such multiemployer plan.

                 3.15.(b) Terminations, Proceedings, Penalties, etc.  With

            reason of the complete or partial termination of any such plan, the
            funded status of any such plan, any "complete withdrawal" (as
            defined in Section 4203 of ERISA) or "partial withdrawal" (as
            defined in Section 4205 of ERISA) by any person from any such plan,

                  lien under Title IV of ERISA;

                       (ii) no proceeding has been initiated or, to the
                  knowledge of the Shareholders, threatened by any person

                       (iv) if any such plan were to be terminated as of the
                  Closing Date, no assets of Company would be subject, directly

            "prohibited transactions" within the meaning of Section 406 or 407

            Employee Plan/Agreement which is intended to be a funded plan equal
            or exceed the amounts required to be paid, or which would be
            required to be paid if such Employee Plan/Agreement were
            terminated, on account of rights vested or accrued as of the

            Section 401 of the Code has received a favorable determination
            letter from the Internal Revenue Service with respect to such
            qualification, its related trust has been determined to be exempt
            from taxation under Section 501(a) of the Code, and nothing has
            occurred since the date of such letter that has or is likely to
            adversely affect such qualification or exemption; (v) there are no

injunctive relief or alleges damages (whether or not covered by insurance).  The
provision of such services by the Company meets and complies with all
governmental laws and regulations currently in effect.  As used in this Section
3.19, the term "Services" means any and all services currently or at any time

            Company or is competitive with Company's business, or (ii) any
            property, asset or right which is used by Company in the conduct of

     3.23. No Brokers or Finders.  Neither Company nor any of its directors,
officers, employees, Shareholders or agents have retained, employed or used any
broker or finder in connection with the transaction provided for herein or in
connection with the negotiation thereof.

     3.24. Year 2000 Compliance.  Except as disclosed on Schedule 3.24, to the
knowledge of the Shareholders:  (a) the computer source codes, programs and
other software of the Company (including machine readable code, printed
listings of code, databases, documentation and related property and information
of Company used or under development for use in the BMC Business)
(collectively, "Software") accurately determines chronological 

                                       25

<PAGE>   31


dates and accurately performs all calculations, data manipulations, sorting and
transmission of date data regardless of whether the date represents or
references different centuries (For example, when the actual date changes from
12/31/1999 to 1/1/2000, the Software will accurately determine that 1/1/2000 is
the new date and determine that an individual born in 1948 is 52 years old and
not -48 [i.e., 00-48 = -48], or otherwise incorrectly perform the age
calculation); (b) the Software provides that all date related user interface
functionalities and data fields permit the entry of a four digit year (i.e.,
the years 1965, 2065 and 3065 could all be entered by the user without the need
of a manual override) and such date data will result in accurate calculations,
data manipulations, sorting and transmission of all data, including the date
data; (c) the entry of a date equal to or greater than 01/01/2000 into the
Software will not affect any calculation that produces or uses time spans such
that the results of the calculation are incorrect (i.e., such as an interest
calculation); and (d) the integrity of calculations performed utilizing the
Software will not be affected by date data for dates on or after 01/02/2000,
and calculations using previously generated data (on or before 12/31/1999) will
also maintain calculation integrity.

     3.25. Systems Performance.  To the knowledge of the Shareholders, the
Software and related system components are capable of interconnecting and/or
interfacing with each other, and they deliver the functionality needed to meet
the information systems requirements of the BMC Business as they are presently
conducted.  No Shareholder will cause any unplanned interruption of the
operations of, or accessibility to, the Software or related systems (or any
system component) through any device, method or means including, without
limitation, the use of any "virus," "lockup," "time bomb" or "key lock" device
or program, or disabling code, which has the potential or capability of causing
any unplanned interruption of the operations of, or accessibility of, the
Software or related systems (or any system component) to Buyer, or any user
authorized by Buyer, or which could alter, destroy or inhibit the use of the
Software or related systems (or any system component), or the data contained
therein (collectively, "Disabling Devices"), which could block access to or
prevent the use of the Software or any system (or system component) by Buyer or
any authorized user.  No Shareholder has placed, nor is any Shareholder aware
of, any Disabling Device on any Software or system component owned or used by
Company. To the knowledge of the Principal Shareholder, there is no new
version, update or release of any Software currently being developed, other
than standard updates the release of which will not render the existing version
obsolete.

     3.26. Software Ownership; Non Infringement.  The Company only utilizes
software purchased ("Purchased Software") or licensed ("Licensed Software") from
unaffiliated third party software vendors.  The Company owns all right, title
and interest in and to the Purchased Software. With respect to Licensed
Software, Company has duly obtained the right and license to use the software as
currently utilized by the Company.

     3.27. Disclosure. No representation or warranty by Company and/or the
Shareholders in this Agreement, nor any statement, certificate, schedule,
document or exhibit hereto furnished or to be furnished by or on behalf of
Company or Shareholders pursuant to 

                                       26

material fact necessary to make the statements contained therein not misleading.
All statements and information contained in any certificate, instrument,
Disclosure Schedule or document delivered by or on behalf of Company and/or

     5.   COVENANTS

     5.1. Employment and Noncompetition Agreements.  Contemporaneously with the
execution of this Agreement, Principal Shareholder shall execute and deliver to
Company an Employment and Noncompetition Agreement, substantially in the form
of exhibit A hereto.

     5.2. Noncompetition; Confidentiality.  As an inducement to Buyer to
execute this Agreement and complete the transactions contemplated hereby, and
in order to preserve the goodwill associated with the business of Company being
acquired pursuant to this Agreement, and in addition to and not in limitation
of any covenants contained in any agreement executed and delivered pursuant to
Section 5.1 hereof, Principal Shareholder hereby covenants and agrees as
follows:

                 5.2.(a) Covenant Not to Compete.  For a period of three (3)
            years from the Closing Date, Principal Shareholder will not
            directly or indirectly:

                       (i) engage in, continue in or carry on any business
                  which competes with Company or the BMC Business or is
                  substantially similar thereto, including owning or
                  controlling any financial interest in any corporation,
                  partnership, firm or other form of business organization
                  which is so engaged;

                       (ii) consult with, advise or assist in any way, whether
                  or not for consideration, any corporation, partnership, firm
                  or other business organization which is now or becomes a
                  competitor of Company or Buyer (or any of its subsidiaries)
                  in any aspect with respect to the BMC
                  Business, including, but not limited to, advertising or
                  otherwise endorsing the products of any such competitor;
                  soliciting customers or otherwise serving as an intermediary
                  for any such competitor; loaning money or rendering any other
                  form of financial assistance to or engaging in any form of
                  business transaction on other than an arm's length basis with
                  any such competitor;

                       (iii) offer employment to an employee of Company or the
                  BMC Business, without the prior written consent of Buyer; or

                       (iv) engage in any practice the purpose of which is to
                  evade the provisions of this covenant not to compete or to
                  commit any act which adversely affects the Company or the BMC
                  Business;

                                       28
<PAGE>   34

provided, however, that the foregoing shall not prohibit the ownership of
securities of corporations which are listed on a national securities exchange
or traded in the national over-the-counter market in an amount which shall not
exceed 5% of the outstanding shares of any such corporation.  The parties agree
that the geographic scope of this covenant not to compete shall extend to and
cover the entire state of Colorado.  The parties agree that a Buyer may sell,
assign or otherwise transfer this covenant not to compete, in whole or in part,
to any subsidiary of Buyer or to any person, corporation, firm or entity that
purchases all or part of the business of the Company.  In the event a court of
competent jurisdiction determines that the provisions of this covenant not to
compete are excessively broad as to duration, geographical scope or activity,
it is expressly agreed that this covenant not to compete shall be construed so
that the remaining provisions shall not be affected, but shall remain in full
force and effect, and any such over broad provisions shall be deemed, without
further action on the part of any person, to be modified, amended and/or
limited but only to the extent necessary to render the same valid and
enforceable in such jurisdiction.

                 5.2.(b) Covenant of Confidentiality.  No Shareholder shall at
            any time subsequent to the Closing, except as explicitly requested
            by Buyer, (i) use for any purpose, (ii) disclose to any person, or
            (iii) keep or make copies of documents, tapes, discs or programs
            containing, any confidential information concerning Company.  For
            purposes hereof, "confidential information" shall mean and include,
            without limitation, all Trade Rights in which Company has an
            interest, all customer lists and customer information, and all
            other information concerning Company's processes, apparatus,
            equipment, packaging, products, marketing and distribution methods,
            not previously disclosed to the public directly by Company.

                 5.2.(c) Equitable Relief for Violations.  Each Shareholder
            agrees that the provisions and restrictions contained in this
            Section 5.2 are necessary to protect the legitimate continuing
            interests of Buyer in acquiring the Shares, and that any violation
            or breach of these provisions will result in irreparable injury to
            Buyer for which a remedy at law would be inadequate and that, in
            addition to any relief at law which may be available to Buyer for
            such violation or breach and regardless of any other provision
            contained in this Agreement, Buyer shall be entitled to injunctive
            and other equitable relief as a court may grant after considering
            the intent of this Section 5.2.

     5.3. General Releases.  Contemporaneously with the execution of this
Agreement, each Shareholder shall deliver a general release to Buyer, in
substantially the form attached hereto as Exhibit B.

     5.4. Section 338(h)(10) Election.  At the Buyer's option, Company and
Shareholders will join with the Buyer in making an election under Section
338(h)(10) of the Code (and any corresponding elections under state tax law)
(collectively, a "Section 338(h)(10) Election") with respect to the purchase
and sale of the stock of the Company hereunder.  The Shareholders of the
Company will pay any tax attributable to the making of the Section 

                                       29
<PAGE>   35
338(h)(10) Election and will indemnify the Buyer, the Company and their
subsidiaries against any tax (including interest and penalties) arising out of
any failure to pay such tax. The Shareholders will also pay any state, local,
or foreign tax (and indemnify the Buyer, the Company and their subsidiaries
against any tax (including interest and penalties) arising out of any failure to
pay such tax) attributable to an election under state, local, or foreign law
similar to the election available under Section 338(g) of the Code (or which
results from the making of an election under Section 338(g) of the Code) with
respect to the purchase and sale of the stock of the Company hereunder. Buyer
shall be responsible for the preparation and filing of such election. The
allocation of purchase price among the assets of the Company shall be made in
accordance with book values reflected in the Recent Balance Sheet, an amount not
to exceed $80,000 for noncompete assets, and the remainder to goodwill.
Shareholders and Buyer shall accept such purchase price allocations and Buyer
and each Shareholder shall report, act, file in all respects and for purposes
consistent with such allocations. Shareholders and the Company (if required)
shall execute and deliver to Buyer at Closing three copies of such documents or
forms (including Section 338 Forms, as defined below) as Buyer shall request or
as are required by applicable law for an effective Section 338(h)(10) Election,
including, without limitation, any "Statement of Section 338(h)(10)" and IRS
Form 8023 (together with any schedules or attachments thereto, the "Section 338
Forms") that are required pursuant to the Treasury Regulations.

     5.5. Employees of Company.  To the extent permitted under the terms and
provisions of any benefit plans of Company (or its parent corporation) which
are made available to the employees of Company generally, the employees of
Company shall receive credit for years of service to Company for the purpose of
determining benefits for which such employees are eligible.

     6.   INDEMNIFICATION

     6.1. By Principal Shareholder.  Subject to the terms and conditions of
this Article 6, Principal Shareholder, hereby agrees to indemnify, defend and
hold harmless Buyer, its directors, officers, employees and controlled and
controlling persons (hereinafter "Buyer's Affiliates") and the Company from and
against all Claims asserted against, resulting to, imposed upon, or incurred by
Buyer, Buyer's Affiliates or the Company, directly or indirectly, by reason of,
arising out of or resulting from (a) the inaccuracy or breach of any
representation or warranty of any Shareholder (including Principal Shareholder)
or Company contained in or made pursuant to this Agreement, (b) the breach of
any covenant of any Shareholder (including Principal Shareholder) or the
Company contained in this Agreement, (c) the litigation matters referred to in
Schedule 3.9, or (d) the conduct of the BMC Business or operations of the
Company prior to the Closing (other than Claims for liabilities to the extent
the amounts thereof are specifically reflected in the Recent Balance Sheet).
As used in this Article 6, the term "Claim" shall include (i) all debts,
liabilities and obligations; (ii) all losses, damages (including, without
limitation, consequential damages), judgments, awards, settlements, costs and
expenses (including, without limitation, interest (including prejudgment
interest in any litigated matter), penalties, court costs and attorneys fees
and expenses); and (iii) all demands,

                                       30
<PAGE>   36

claims, suits, actions, costs of investigation, causes of action, proceedings
and assessments, whether or not ultimately determined to be valid.

     6.2. By Buyer.  Subject to the terms and conditions of this Article 6,
Buyer hereby agrees to indemnify, defend and hold harmless each Shareholder
from and against all Claims asserted against, resulting to, imposed upon or
incurred by any such person, directly or indirectly, by reason of or resulting
from (a) the inaccuracy or breach of any representation or warranty of Buyer
contained in or made pursuant to this Agreement, or (b) the breach of any
covenant of Buyer contained in this Agreement.

     6.3. Indemnification of Third-Party Claims.  The obligations and
liabilities of any party to indemnify any other under this Article 6 with
respect to Claims relating to third parties shall be subject to the following
terms and conditions:

                 6.3.(a) Notice and Defense.  The party or parties to be
            indemnified (whether one or more, the "Indemnified Party") will
            give the party from whom indemnification is sought (the
            "Indemnifying Party") prompt written notice of any such Claim, and
            the Indemnifying Party will undertake the defense thereof by
            representatives chosen by it.  In all matters concerning the
            Shareholders, the Shareholders' Agent shall give and receive notice
            and otherwise act in all respects on their behalf.  Failure to give
            such notice shall not affect the Indemnifying Party's duty or
            obligations under this Article 6, except to the extent the
            Indemnifying Party is prejudiced thereby.  So long as the
            Indemnifying Party is defending any such Claim actively and in good
            faith, the Indemnified Party shall not settle such Claim.  The
            Indemnified Party shall make available to the Indemnifying Party or
            its representatives all records and other materials required by
            them and in the possession or under the control of the Indemnified
            Party, for the use of the Indemnifying Party and its
            representatives in defending any such Claim, and shall in other
            respects give reasonable cooperation in such defense.

                 6.3.(b) Failure to Defend.  If the Indemnifying Party, within
            a reasonable time after notice of any such Claim, fails to defend
            such Claim actively and in good faith, the Indemnified Party will
            (upon further notice) have the right to undertake the defense,
            compromise or settlement of such Claim or consent to the entry of a
            judgment with respect to such Claim, on behalf of and for the
            account and risk of the Indemnifying Party, and the Indemnifying
            Party shall thereafter have no right to challenge the Indemnified
            Party's defense, compromise, settlement or consent to judgment
            therein.

                 6.3.(c) Indemnified Party's Rights.  Anything in this Section
            6.3 to the contrary notwithstanding, (i) if there is a reasonable
            probability that a Claim may materially and adversely affect the
            Indemnified Party other than as a result of money damages or other
            money payments, the Indemnified Party shall have the right to
            defend, compromise or settle such Claim, and (ii) the 

                                       31

<PAGE>   37

            Indemnifying Party shall not, without the written consent of the
            Indemnified Party, settle or compromise any Claim or consent to the
            entry of any judgment which does not include as an unconditional
            term thereof the giving by the claimant or the plaintiff to the
            Indemnified Party of a release from all Liability in respect of such
            Claim.

     6.4. Payment.  The Indemnifying Party shall promptly pay the Indemnified
Party any amount due under this Article 6, which payment may be accomplished in
whole or in part, at the option of the Indemnified Party, by the Indemnified
Party setting off any amount owed to the Indemnifying Party by the Indemnified
Party.  To the extent set-off is made by an Indemnified Party in satisfaction
or partial satisfaction of an indemnity obligation under this Article 6 that is
disputed by the Indemnifying Party, upon a subsequent determination by final
judgment not subject to appeal that all or a portion of such indemnity
obligation was not owed to the Indemnified Party, the Indemnified Party shall
pay the Indemnifying Party the amount which was set-off and not owed together
with interest from the date of set-off until the date of such payment at an
annual rate equal to the prime rate (as announced by the Wall Street Journal)
in effect as of the date of the set-off.  Upon judgment, determination,
settlement or compromise of any third party Claim, the Indemnifying Party shall
pay promptly on behalf of the Indemnified Party, and/or to the Indemnified
Party in reimbursement of any amount theretofore required to be paid by it, the
amount so determined by judgment, determination, settlement or compromise and
all other Claims of the Indemnified Party with respect thereto, unless in the
case of a judgment an appeal is made from the judgment.  If the Indemnifying
Party desires to appeal from an adverse judgment, then the Indemnifying Party
shall post and pay the cost of the security or bond to stay execution of the
judgment pending appeal.  Upon the payment in full by the Indemnifying Party of
such amounts, the Indemnifying Party shall succeed to the rights of such
Indemnified Party, to the extent not waived in settlement, against the third
party who made such third party Claim.

     6.5. Indemnification for Environmental Matters.  Without limiting the
generality of the foregoing, Principal Shareholder agrees to indemnify,
reimburse, hold harmless and defend Buyer, Buyer's affiliates and Company for,
from, and against all Claims asserted against, imposed on, or incurred by any
such person, directly or indirectly, in connection with any pollution, threat
to the environment, or exposure to, or manufacture, processing, distribution,
use, treatment, generation, transport or handling, disposal, emission,
discharge, storage or release of Waste that (A) is related in any way to
Company's or any previous owner's or operator's ownership, operation or
occupancy of the business, properties and assets owned or used by Company, and
(B) in whole or in part occurred, existed, arose out of conditions or
circumstances that existed, or was caused on or before the Closing Date.

     6.6. Limitations on Indemnification.  Except for any willful or knowing
breach or misrepresentation, as to which claims may be brought without
limitation as to time or amount:

                 6.6.(a) Time Limitation.  No claim or action shall be brought
            under this Article 6 for breach of a representation or warranty
            after the lapse of 

                                       32

<PAGE>   38
            two (2) years following the Closing.  Regardless of the foregoing,
            however, or any other provision of this Agreement:

                       (i) There shall be no time limitation on claims on
                  actions brought for breach of any representation or warranty
                  made by Shareholders or Company in or pursuant to Sections
                  3.1, 3.2, 3.9 and 3.10, and as between Buyer and the
                  Principal Shareholder, the Principal Shareholder hereby
                  waives all applicable statutory limitation periods with
                  respect thereto.

                       (ii) Any claim or action brought for breach of any
                  representation or warranty made by the Principal Shareholder
                  with respect to tax or ERISA matters may be brought at any
                  time until the underlying tax or ERISA obligation is barred
                  by the applicable period of limitation under federal and
                  state laws relating thereto (as such period may be extended
                  by waiver).

                       (iii) Any claim made by a party hereunder by delivering
                  written notice of the claim to the Indemnifying Party or
                  Parties, by filing a suit or action in a court of competent
                  jurisdiction or a court reasonably believed to be of
                  competent jurisdiction or by a demand for arbitration in
                  accordance with Article 9 hereof for breach of a
                  representation or warranty prior to the termination of the
                  survival period for such claim shall be preserved despite the
                  subsequent termination of such survival period.

                       (iv) If any act, omission, disclosure or failure to
                  disclosure shall form the basis for a claim for breach of
                  more than one representation or warranty, and such claims
                  have different periods of survival hereunder, the termination
                  of the survival period of one claim shall not affect a
                  party's right to make a claim based on the breach of
                  representation or warranty still surviving.

                 6.6.(b) Amount Limitation.  The Principal Shareholder shall
            have no liability under this Article 6 to indemnify Buyer or
            Buyer's Affiliates from any loss, damage or cost associated with or
            relating to a claim unless and until the aggregate amount of
            losses, damages and costs exceeds $50,000; but in such event,
            Buyer, Buyer's Affiliates and Company shall be entitled to
            indemnification in full except as otherwise limited herein. The
            aggregate amount of the indemnification obligations of the
            Principal Shareholder pursuant to this Article 6 shall not exceed
            92% of the aggregate Purchase Price as set forth in Section 2.1;
            provided, however, that there shall be no amount limitation on
            claims or actions brought for breach of any representation or
            warranty made by the Principal Shareholder in or pursuant to
            Sections 3.1, 3.2, 3.5 and 3.15.

                                       33
<PAGE>   39


     6.7. No Waiver.  The closing of the transactions contemplated by this
Agreement shall not constitute a waiver by any party of its rights to
indemnification hereunder, regardless of whether the party seeking
indemnification has knowledge of the breach, violation or failure of condition
constituting the basis of the Claim at or before the Closing, and regardless of
whether such breach, violation or failure is deemed to be "material" for
purposes of Section 9.2.

      9.   RESOLUTION OF DISPUTES

           9.1. Arbitration.

                 9.1.(a) Any dispute, controversy or claim arising out of or
            relating to this Agreement or any contract or agreement entered
            into pursuant hereto or the performance by the parties of its or
            their terms shall be settled by binding arbitration held in Tampa,
            Florida in accordance with the Commercial Arbitration Rules of the
            American Arbitration Association then in effect, except as
            specifically otherwise provided in this Article 9.  Notwithstanding
            the foregoing, Buyer may, in its discretion, apply to a court of
            competent jurisdiction for equitable relief from any violation or
            threatened violation of the covenants of Principal Shareholder
            under Section 5.2 of this Agreement, or any covenants not to
            compete contained in any Employment and Noncompetition Agreement
            delivered pursuant to Section 5.1 hereof.

                 9.1.(b) No party shall be required to submit to arbitration
            hereunder unless all persons who are not parties to this Agreement,
            but who are necessary parties to a complete resolution of the
            controversy, submit to the arbitration process on the same terms as
            the parties hereto.  Without limiting the generality of the
            foregoing, no claim under Article 6 for the indemnification of a
            third-party claim shall be subject to arbitration under this
            Article 9 unless the third party bringing such claim against the
            indemnitee shall agree in writing to the application of this
            Article 9 to the resolution of such claim.

     9.2. Arbitrators.  If the matter in controversy (exclusive of attorney
fees and expenses) shall appear, as at the time of the demand for arbitration,
to exceed $250,000, then the panel to be appointed shall consist of three
neutral arbitrators; otherwise, one neutral arbitrator.

<PAGE>   42


     9.3. Procedures; No Appeal.  The arbitrator(s) shall allow such discovery
as the arbitrator(s) determine appropriate under the circumstances and shall
resolve the dispute as expeditiously as practicable, and if reasonably
practicable, within 120 days after the selection of the arbitrator(s).  The
arbitrator(s) shall give the parties written notice of the decision, with the
reasons therefor set out, and shall have 30 days thereafter to reconsider and
modify such decision if any party so requests within 10 days after the
decision.  Thereafter, the decision of the arbitrator(s) shall be final,
binding, and nonappealable with respect to all persons, including (without
limitation) persons who have failed or refused to participate in the
arbitration process.

     9.4. Authority.  The arbitrator(s) shall have authority to award relief
under legal or equitable principles, including interim or preliminary relief,
and to allocate responsibility for the costs of the arbitration and to award
recovery of attorneys fees and expenses in such manner as is determined to be
appropriate by the arbitrator(s).

     9.5. Entry of Judgment.  Judgment upon the award rendered by the
arbitrator(s) may be entered in any court having in personam and subject matter
jurisdiction.  Buyer and each Shareholder hereby submit to the in personam
jurisdiction of the Federal and State courts in Florida, for the purpose of
confirming any such award and entering judgment thereon.

     9.6. Confidentiality.  All proceedings under this Article 9 and all
evidence given or discovered pursuant hereto, shall be maintained in confidence
by all parties.

     9.7. Continued Performance.  The fact that the dispute resolution
procedures specified in this Article 9 shall have been or may be invoked shall
not excuse any party from performing its obligations under this Agreement and
during the pendency of any such procedure all parties shall continue to perform
their respective obligations in good faith, subject to any rights to terminate
this Agreement that may be available to any party and to the right of setoff
provided in Section 6.4 hereof.

     9.8. Tolling.  All applicable statutes of limitation shall be tolled while
the procedures specified in this Article 9 are pending.  The parties will take
such action, if any, required to effectuate such tolling.
