<PAGE>

         NOW, THEREFORE, in consideration of the premises and the mutual
promises and agreements contained herein, the parties hereto, intending to be
legally bound, hereby agree as follows:

SECTION 1.        PURCHASE OF OSBORN SHARES.

         1.1      Transfer of Osborn Shares. On the terms and subject to the
conditions set forth in this Agreement, ChoicePoint hereby sells, assigns,
transfers, and delivers to LabOne, and LabOne hereby purchases from ChoicePoint,
one (1) share of common stock of Osborn (the "Osborn Shares"), which Osborn
Shares constitute all of the issued and outstanding shares of capital stock of
Osborn.

         1.2      Purchase Price. On the terms and subject to the conditions set
forth in this Agreement, in consideration for all of the Osborn Shares, subject
to adjustment pursuant to Section 1.4, LabOne shall pay to ChoicePoint the
purchase price (the "Purchase Price") for the Osborn Shares in the amount of
FORTY-EIGHT MILLION SIX HUNDRED FIFTY THOUSAND DOLLARS ($48,650,000), which
amount LabOne hereby pays in accordance with Section 1.3.

         1.3      Delivery of Osborn Shares and Payment of Purchase Price.
Contemporaneously with the execution of this Agreement, (a) against delivery of
the Purchase Price, ChoicePoint is delivering to LabOne a certificate or
certificates in definitive form evidencing the Osborn Shares, duly endorsed for
transfer, or accompanied by a stock transfer power duly endorsed in blank, with
all requisite stock transfer Taxes (as hereinafter defined) paid and stamps
affixed, and (b) against delivery of the Osborn Shares, LabOne is delivering or
causing to be delivered to ChoicePoint by wire transfer of immediately available
funds the amount of FORTY-EIGHT MILLION SIX HUNDRED FIFTY THOUSAND DOLLARS
($48,650,000), which amount is being wire transferred to ChoicePoint's account
number 13-028-140 (ChoicePoint Inc. - Master Account) at Wachovia Bank of
Georgia (ABA #061-000-010), Atlanta, Georgia.

         1.4      Working Capital Adjustment.

                  (a)      Definition of Net Working Capital. For purposes of
         this Section 1.4, the term "Net Working Capital" means the "Current
         Assets" (as hereinafter defined) over the "Current Liabilities" (as
         hereinafter defined) of the Osborn Entities, as of 5:00 p.m., Kansas
         City, Missouri time, on the date hereof (the "Statement Date"), in each
         case as determined, except as otherwise provided herein, in accordance
         with generally accepted accounting principles applied consistently with
         past practices ("GAAP"). As used herein, the term "Current Assets"
         means those assets of the type listed on Annex 1 hereto (less
         applicable reserves), and the term "Current Liabilities" means those
         liabilities of the type listed on Annex 2 hereto. For the purposes of
         determining the "Net Working Capital", it is understood that Osborn
         Canada shall continue to be considered an Osborn Entity notwithstanding
         the sale of the "Osborn Canada Shares" (as hereinafter defined) to
         LabOne pursuant to Section 2.4 hereof prior to the sale and purchase of
         the Osborn Shares.

                                      -2-
<PAGE>

                  (b)      Preparation of Proposed Working Capital Statement.
         Within sixty (60) days after the date hereof, LabOne shall prepare and
         deliver to ChoicePoint, at the sole expense of LabOne, a statement of
         the Osborn Entities (the "Proposed Working Capital Statement"), which
         Proposed Working Capital Statement shall set forth its proposed
         calculation of the Current Assets, the Current Liabilities, and the Net
         Working Capital as of the Statement Date and shall make available to
         ChoicePoint for review and copying all work papers relating to the
         Proposed Working Capital Statement. Except as otherwise provided herein
         or set forth on Annex 3 hereto, the Proposed Working Capital Statement
         shall be prepared in accordance with GAAP after giving effect (except
         as hereinafter noted) to the transactions (the "Pre-Closing
         Transactions") contemplated by this Agreement (including, without
         limitation, each of the transactions described in Sections 2.1, 2.2,
         2.3, 2.5 and 2.6 hereof, but excluding the transaction described in
         Section 2.4 hereof ). For the purposes of the determination of the Net
         Working Capital and the Final Working Capital Statement, the
         Pre-Closing Transactions shall be deemed to have been completed on or
         prior to the Statement Date.

                  (c)      Examination of Proposed Working Capital Statement.
         ChoicePoint shall review the Proposed Working Capital Statement to
         confirm the accuracy of the Proposed Working Capital Statement and of
         LabOne's calculation of the Net Working Capital. If ChoicePoint fails
         to give LabOne written notice of any disputed amounts within thirty
         (30) days after ChoicePoint receives the Proposed Working Capital
         Statement (the "Review Period"), then the Proposed Working Capital
         Statement shall become the "Final Working Capital Statement" (as
         hereinafter defined) for purposes hereof. If ChoicePoint gives LabOne
         written notice of any disputed items and its proposed calculation of
         Net Working Capital within the Review Period, ChoicePoint and LabOne
         shall attempt in good faith to agree on any adjustments that should be
         made to the Proposed Working Capital Statement in order to reflect the
         Net Working Capital. If ChoicePoint and LabOne are unable to resolve
         any disputed amounts within sixty (60) days after ChoicePoint receives
         the Proposed Working Capital Statement, ChoicePoint and LabOne will
         engage the Kansas City, Missouri office of PricewaterhouseCoopers LLP
         (the "Audit Firm") to resolve any such disputed matters in accordance
         with the terms of this Agreement. If possible, the decision of the
         Audit Firm shall be made within thirty (30) days after being engaged.
         The decision of the Audit Firm shall be final and binding on the
         parties. The Proposed Working Capital Statement shall be revised, if
         necessary, to reflect the final determination of the Net Working
         Capital (the final form of the Proposed Working Capital Statement,
         including any revisions which are made thereto pursuant to this Section
         1.4(c), is referred to herein as the "Final Working Capital
         Statement").

                  (d)      Adjustments. The parties hereto acknowledge that the
         consideration being paid to ChoicePoint pursuant to Section 1.2 is
         based on the assumption that the Net Working Capital of Osborn shall be
         equal to -$719,731 (the "Assumed Net Working Capital"). Accordingly,
         the parties hereto agree that if the Net Working Capital as reflected
         on the Final Working Capital Statement is less than the Assumed Net
         Working Capital (i.e., the Assumed Net Working Capital is -$719,732 or
         a greater negative number) (the amount of such shortfall, if any, is
         hereinafter referred to as the "Working Capital Deficit"), ChoicePoint
         shall pay to LabOne, on a dollar for dollar basis, an amount equal to
         the Working Capital Deficit (such payment shall be hereinafter referred

                                      -3-
<PAGE>

         to as a "Working Capital Payment"). The Working Capital Payment, if
         any, shall be paid to LabOne within ten (10) days of the final
         determination of the Final Working Capital Statement. If the Net
         Working Capital as reflected on the Final Working Capital Statement is
         greater than the Assumed Net Working Capital (i.e., the Assumed Net
         Working Capital is -$719,730 or either a lesser negative number or zero
         or a positive number) (the amount of such excess is hereinafter
         referred to as the "Working Capital Surplus"), LabOne shall pay to
         ChoicePoint, on a dollar for dollar basis, an amount equal to the
         Working Capital Surplus. The Working Capital Surplus, if any, shall be
         paid by LabOne to ChoicePoint within ten (10) days of the final
         determination of the Final Working Capital Statement. The determination
         of the Working Capital Deficit or the Working Capital Surplus, as the
         case may be, shall be made immediately following the final
         determination of the Final Working Capital Statement.

                  (e)      Expenses of Audit Firm. In the event the parties
         submit any unresolved objections to the Audit Firm for resolution as
         provided in Section 1.4(c) above, LabOne, on the one hand, and the
         ChoicePoint Entities, jointly and severally, on the other hand, will
         each be obligated to pay fifty percent (50%) of the fees and expenses
         of the Audit Firm; provided, however, that if the Audit Firm's final
         determination of Net Working Capital varies from either LabOne's or
         ChoicePoint's determination of Net Working Capital (but not both) by
         more than ten percent (10%), the party whose determination of Net
         Working Capital so varied by more than ten percent (10%) from that of
         the Audit Firm shall bear one hundred percent (100%) of the Audit
         Firm's fees and expenses.

         SECTION 2.        RELATED MATTERS.

         2.1      Transfer of Real Property.

                  (a)      Prior to or on the date hereof, the Osborn Entities
         have transferred to ChoicePoint all of the Owned Real Property (as
         defined in Section 3.5(a)), together with all benefits and liabilities

SECTION 3.        REPRESENTATIONS AND WARRANTIES OF THE CHOICEPOINT ENTITIES.

         Each of the ChoicePoint Entities hereby jointly and severally
represents and warrants to LabOne as follows:

         3.1      Organization. ChoicePoint is a corporation duly incorporated,
validly existing, and in good standing under the Laws of the State of Georgia.
Osborn is a corporation duly incorporated, validly existing, and in good
standing under the Laws of the State of Delaware. Each of the Osborn
Subsidiaries is a corporation duly incorporated, validly existing, and in good
standing under the Laws of the jurisdiction of its incorporation. Each of
ChoicePoint and the Osborn Entities has all requisite corporate power and
authority to own, lease, and operate its properties and to carry on its business
as now being conducted. Except as disclosed on Schedule 3.1, each of the Osborn
Entities is duly qualified to transact business and is in good standing as a
foreign corporation in each jurisdiction where the character of its activities
or the location of its owned or leased properties requires such qualification,
except where the failure to so qualify would not have a Material Adverse Effect.
As used in this Agreement, the term "Material Adverse Effect" means any change,
effect, condition, event or circumstance that has been, is, or is reasonably
likely to be materially adverse to the financial condition, business, or results
of operations of the Osborn Entities. ChoicePoint has heretofore made available
to LabOne correct and complete copies of the charter documents and bylaws (or
other governing documents) as currently in effect and the minute books and stock
records of the Osborn Entities. The minute books and stock records of the Osborn
Entities are complete and correct and

                                      -6-

accurately reflect in all material respects all action taken at all meetings of
the shareholders and Boards of Directors (and committees thereof, if any) of
such entities and accurately record the issuance and transfer of all issued
shares of capital stock of such entities. Schedule 3.1 contains a correct and
complete list of the jurisdictions in which each of the Osborn Entities is
qualified to do business as a foreign corporation. None of the Osborn Entities
is in default in the performance, observance or fulfillment of any provision of
its charter or bylaws (or other governing documents).

         3.2      Authorization. ChoicePoint has the corporate power and
authority to execute and deliver this Agreement, the Transition Services
Agreement and each other certificate, instrument and agreement executed and
delivered in connection with this Agreement (together with the Transition
Services Agreement, the "Ancillary Agreements") to which it is party, and
perform its obligations hereunder and thereunder. The execution and delivery of
this Agreement and each Ancillary Agreement to which it is a party and the
performance by ChoicePoint of its covenants and agreements hereunder and
thereunder have been duly and validly authorized by the Board of Directors of
ChoicePoint, and no other corporate proceedings on the part of ChoicePoint or
its Affiliates are necessary to authorize the execution, delivery and
performance of this Agreement and each Ancillary Agreement to which it is a
party or the consummation of the transactions so contemplated. Each of this
Agreement and each Ancillary Agreement to which it is party has been duly
executed and delivered by ChoicePoint and constitutes a valid and binding
agreement of ChoicePoint, enforceable against ChoicePoint in accordance with its
terms, except that (a) such enforcement may be subject to any bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or other Laws, now
or hereafter in effect, relating to or limiting creditors' rights generally and
(b) the remedy of specific performance and injunctive and other forms of
equitable relief may be subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought. As used herein,
"Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this Agreement, (i)
"control", when used with respect to any specified Person, means the power to
direct the management and policies of such Person, directly or indirectly,
whether through the ownership of voting securities, by contract, or otherwise,

and (iii) "Person" means any individual, corporation, partnership, limited
liability company, joint venture, trust, unincorporated organization, or other
entity or any government or any agency or political subdivision thereof.

         3.3      Absence of Restrictions and Conflicts. The execution,
delivery, and performance of this Agreement and the Ancillary Agreements, the
consummation of the transactions contemplated by this Agreement and the
Ancillary Agreements, and the fulfillment of and compliance with the terms and
conditions of this Agreement and the Ancillary Agreements do not and will not
(as the case may be), with or without the passing of time or the giving of
notice or both, violate or conflict with, constitute a breach of or default
under, result in any penalty or payment becoming due under, result in the loss
of any benefit under, or permit the acceleration or termination of any right or
obligation under, (a) any term or provision of the charter documents or bylaws
(or other governing documents) of ChoicePoint or any Osborn Entity, (b) except

         potentially responsible) for the cleanup of any pollutants,
         contaminants or hazardous or toxic wastes, substances or materials at,

         behalf thereof, acting alone or together, has (i) received, directly or
         indirectly, any rebates, payments, commissions, promotional allowances

         such Osborn Entity for the payment of all such Taxes with respect to

         taxable period (or portion thereof) ending on or prior to the date
         hereof. Such Tax Returns are correct and complete in all material

                  (b)      There are no Liens for Taxes with respect to the
         assets of the Osborn Entities (except for statutory liens for current

         ChoicePoint Entity on behalf of any Osborn Entity has filed a consent

         and, for such periods, all federal income tax returns required to be
         filed by each Osborn Entity have been (or will be) duly and timely
         filed on behalf of such Osborn Entity on a consolidated basis. All
         other Tax Returns of each Osborn Entity have been filed on a separate
         company, non-combined, non-consolidated and non-unitary basis.

         tax ruling or entered into a legally binding agreement (such as a
         closing agreement) with a taxing authority, which ruling or agreement
         could have an effect on the Taxes of any Osborn Entity after the date
         hereof, or (ii) filed any election, or caused any deemed election,
         under Section 338 of the Code.

         Entity or any Tax Group of which ChoicePoint is the common parent to

         Tax Group of which ChoicePoint is the common parent has been proposed,
         asserted or assessed in writing, and no federal, state, local,
         provincial or foreign audits or other administrative proceedings or
         court proceedings are pending with regard to any such Taxes of any

         ChoicePoint, from November 4, 1994 to August 8, 1997), no written

                  (a)      Schedule 3.13(a) sets forth a correct and complete
         list of all (i) employees employed by each of the Osborn Entities or
         (ii) employees employed by the Parent, ChoicePoint and their Affiliates
         (other than the Osborn Entities) who spend substantially all their time

         job titles, dates of hire, current base salary or hourly rate, bonus
         and severance arrangements with respect thereto and the subsidiary of

         Schedule 3.13(a) under any federal or state Laws

         3.13(a), and except for the consultants, independent contractors and
         leased employees listed on Schedule 3.13(b), the Employees of the
         Osborn Entities are all of employees employed by the Parent,
         ChoicePoint and their Affiliates who spend substantially all their time
         performing services in connection with the administration and operation
         of the Business.

         list of all consultants to and independent contractors or leased
         employees of each of the Osborn Entities, as of the date hereof,

                  (d)      No individual who has been classified by any
         ChoicePoint Entity or Osborn Entity as a non-employee (i.e., an
         independent contractor, leased employee or consultant) has or will have
         a claim against any Osborn Entity for eligibility to participate in any
         employee benefit plan as a result of such individual being reclassified
         as an employee of an Osborn Entity for the period prior to the date
         hereof.

         3.14     ERISA and Related Matters.

                  (a)      Schedule 3.14 lists all deferred compensation,
         pension, profit-sharing, and retirement plans, and all bonus, welfare,
         severance pay, and other "employee benefit plans" (as defined in
         Section 3(3) of ERISA), fringe benefit or stock option plans, including
         individual contracts, employee agreements, programs, or arrangements,
         providing the same or similar benefits, whether or not written, which
         are or have been participated in, or maintained by any Osborn Entity
         (or ChoicePoint Entity for the benefit of employees or former employees
         of any of the Osborn Entities or their dependents and beneficiaries) or
         with respect to which contributions are made or obligations assumed by
         any Osborn Entity (including health, life insurance, and other benefit
         plans maintained for former employees or retirees), at any time between
         August 8, 1997 and the date hereof. Said plans or other arrangements
         are sometimes individually referred to in this Agreement as a "Company
         Benefit Plan" and sometimes collectively referred to in this Agreement
         the "Company Benefit Plans." Copies of all Company Benefit Plans and
         related documents, including those setting out all personnel policies
         and procedures applicable to employees of the Osborn Entities, and
         including any insurance contracts, trust agreements, or other
         arrangements under which benefits are provided, as currently in effect,
         and descriptions of any such plan which are not written have been
         delivered or made available to LabOne. ChoicePoint has also delivered
         to LabOne a copy of the summary plan description, if any, for each
         Company Benefit Plan. As used herein, "Foreign Plan" means any employee
         benefit, pension scheme, retirement, profit sharing, health, dental,
         life or disability insurance plan, as well as any other plan, program
         or arrangement involving direct or indirect compensation, under which
         any Osborn Entity or ChoicePoint Entity has any present or future
         obligations or liability on behalf of any of the non-United
         States-based employees or former employees of any of the Osborn
         Entities or their dependents and beneficiaries, but shall not include
         any program pursuant

                                      -20-

         to which an employee directs payroll-deduction contributions to a
         personal savings account.

                  (b)      Except as set forth on Schedule 3.14, each
         ChoicePoint Entity or Osborn Entity, as applicable, has fulfilled its
         obligations, to the extent applicable, under the minimum funding
         requirements of Section 302 of ERISA and Section 412 of the Code, with
         respect to each "employee benefit plan" (as defined in Section 3(3) of
         ERISA) appearing on Schedule 3.14. Each Company Benefit Plan is in
         substantial compliance with, and has been administered in all material
         respects consistent with, the presently applicable provisions of ERISA,
         the Code, and state Law including but not limited to the satisfaction
         of all applicable reporting and disclosure requirements under the Code,
         ERISA, and state Law. Each ChoicePoint Entity or Osborn Entity, as
         applicable, has made all payments to all Company Benefit Plans required
         by the terms of each such plan in accordance, if applicable, with the
         actuarial and funding assumptions in effect as for the most recent
         actuarial valuation of such plans. No actuarial valuations or reports
         relating to said plans have been required by Law. The ChoicePoint
         Entities or Osborn Entities, as applicable, have filed or caused to be
         filed with the Internal Revenue Service annual reports on Form 5500 for
         each Company Benefit Plan attributable to them for all years and
         periods for which such reports were required and within the time period
         required by ERISA and the Code. Except as disclosed on Schedule 3.14,
         the ChoicePoint Entities or Osborn Entities, as applicable, have funded
         or will fund each Company Benefit Plan attributable to them in
         accordance with its terms through the date hereof including the payment
         of applicable premiums on any insurance contract funding a Company
         Benefit Plan for coverage provided through the date hereof. To the
         extent that any annual contribution for the current year is not yet
         required for any Company Benefit Plan as of the date hereof, the
         ChoicePoint Entities or Osborn Entities, as applicable, have made a pro
         rata contribution to said plan for the period ended at the date hereof
         or said contribution has been accrued on the books of the ChoicePoint
         Entities or Osborn Entities, as applicable.

                  (c)      Except as set forth on Schedule 3.14, to the
         knowledge of ChoicePoint, no non-exempt "prohibited transaction," as
         defined in Section 406 of ERISA and Section 4975 of the Code has
         occurred in respect of any such Company Benefit Plan, and no civil or
         criminal action brought pursuant to Part 5 of Title I or ERISA is
         pending or, to the knowledge of ChoicePoint, is threatened in writing
         or orally against any fiduciary of any such plan.

                  (d)      Except as set forth on Schedule 3.14, the Internal
         Revenue Service has issued a letter for each employee pension benefit
         plan which is a Company Benefit Plan, as defined in Section 3(2) of
         ERISA listed on Schedule 3.14, determining that such plan is a
         qualified plan under Section 401(a) of the Code and is exempt from
         United States Federal Income Tax under Section 501(a) of the Code, and,
         to the knowledge of ChoicePoint, there has been no occurrence since the
         date of any such determination letter which has adversely affected such
         qualification. Except as set forth on Schedule 3.14, none of the
         Company Benefit Plans is intended to qualify under Section 501(c)(9) of
         the Code.

                  (e)      Except as set forth on Schedule 3.14, each Company
         Benefit Plan that provides medical benefits has been operated in
         compliance in all material respects with all requirements of Section
         4980B(f) of the Code and Sections 601 through 608 of ERISA relating to
         continuation of coverage under certain circumstances in which coverage
         would otherwise cease. All former employees of the Osborn Entities
         entitled to such continuation of coverage, or other Persons entitled to
         such continuation of coverage through relationship to said former
         employees, are listed on Schedule 3.14.

                  (f)      None of the ChoicePoint Entities or Osborn Entities
         nor any entity that is treated as a single employer with any of them
         pursuant to Section 414(b), (c), (m), or (o) of the Code currently
         maintains or contributes to any Company Benefit Plan that is subject to
         Title IV of ERISA, nor has previously maintained or contributed to any
         such plan that has resulted in any liability or, to the knowledge of
         ChoicePoint, potential liability for any of the ChoicePoint Entities or
         Osborn Entities under said Title IV. As of the date hereof, there is no
         outstanding unpaid minimum funding waiver within the meaning of Code
         Section 412(d).

                  (g)      Except as disclosed on Schedule 3.14, none of the
         ChoicePoint Entities or Osborn Entities maintains any Company Benefit
         Plan, plans or programs that provide post-retirement medical benefits
         (other than benefits described in this Section 3.14 and those which are
         required by Law), post-employment benefits, death benefits, or other
         post-retirement welfare benefits to any employees or former employees
         of any Osborn Entity or their dependents or beneficiaries. A copy of
         any written description of post-retirement welfare benefits that has
         been provided to any employees or former employees of any Osborn Entity
         or their dependents or beneficiaries has been provided or made
         available to LabOne. Copies of each plan document, insurance contract,
         or other written instrument providing for such post-retirement welfare
         benefits, together with a description of any advance funding
         arrangement that has been established to fund post-retirement welfare
         benefits, has been provided or made available to LabOne. Schedule 3.14
         contains a list of those Persons who are currently retired as of the
         date hereof with a right to any such future post-retirement welfare
         benefits and also contains a list of employees of the Osborn Entities
         who would be currently eligible for post-retirement welfare benefits if
         they retired and satisfied any waiting period provided for under the
         applicable plan.

                  (h)      None of the ChoicePoint Entities or Osborn Entities
         nor any employer referred to in Section 3.14(f) above maintains, nor
         has contributed within the past five (5) years to, any multiemployer
         plan within the meaning of Sections 3(37) or 4001(a)(3) of ERISA. No
         ChoicePoint Entity or Osborn Entity nor any such employer currently has
         any liability to make withdrawal liability payments to any
         multiemployer plan. There is no pending dispute between any ChoicePoint
         Entity or Osborn Entity or any such employer and any multiemployer plan
         concerning payment of contributions or payment of withdrawal liability
         payments.

                  (i)      Except as set forth on Schedule 3.14, no lawsuit or
         complaint against, by, or relating to any Company Benefit Plan or any
         fiduciary, as defined in Section 3(21) of ERISA has been filed or is
         pending.

                  (j)      Each Foreign Plan has been maintained in accordance
         with all applicable Laws and in good standing with each applicable
         Governmental Authority. All contributions have been made with respect
         to all Foreign Plans on a timely basis. None of the Osborn Entities or
         ChoicePoint Entities has incurred any obligation in connection with the
         termination of or withdrawal from any Foreign Plan. The present value
         of the accrued benefit liabilities (whether vested or not) under each
         Foreign Plan, determined as of the end of the Osborn Entities' most
         recently ended fiscal year on the basis of actuarial assumptions
         provided for in such Foreign Plan, did not exceed the current value of
         the assets of such Foreign Plan.

                  (k)      Each Company Benefit Plan that allows loans to plan
         participants has been operated in accordance with its terms, the plan's
         written loan policy and all applicable Laws. In addition, all
         outstanding loans from such Company Benefit Plans are current as of the
         date hereof, and there are no loans in default, as to any employee of
         an Osborn Entity.

                  (l)      For purposes of this Agreement, (i) "ERISA" means the
         Employee Retirement Income Security Act of 1974, as amended from time
         to time, and any regulations or published rulings promulgated or issued
         thereunder and (ii) all references to the ChoicePoint Entities shall be
         deemed to be references to the Parent, ChoicePoint and their
         Affiliates.

individual, including any claim for workers' compensation, (ix) hours worked by
and payments made to employees of the Osborn Entities have not been in violation
of the federal Fair Labor Standards Act or any other Law dealing with such
matters, and (x) there are no controversies pending or, to the knowledge of
ChoicePoint, threatened, between any of the Osborn Entities and any of their
employees.

         5.5      Purchase for Investment.

                  (a)      LabOne is acquiring the Osborn Shares solely for
         investment for its own account and not with the view to, or for resale
         in connection with, any "distribution" (as such term is used in Section
         2(11) of the Securities Act of 1933, as amended (the "Securities Act"))
         thereof. LabOne understands that the Osborn Shares have not been

                                      -27-
<PAGE>

         registered under the Securities Act or any state or foreign securities
         Laws by reason of specified exemptions therefrom that depend upon,
         among other things, the bona fide nature of its investment intent as
         expressed herein and as explicitly acknowledged hereby and that under
         such Laws such securities may not be resold without registration under
         the Securities Act or under applicable state or foreign Law unless an
         applicable exemption from registration is available.

                  (b)      LabOne is an "accredited investor" within the meaning
         of Rule 501 of Regulation D promulgated under the Securities Act.
         LabOne, by reason of its business and financial experience in business,
         has such knowledge, sophistication and experience in business and
         financial matters as to be capable of evaluating the merits and risks
         of the purchase of the Osborn Shares, is able to bear the economic risk
         of such investment in Osborn, and is able to afford a complete loss of
         such investment.

         5.6      Litigation. There is no claim, action, suit, proceeding or
governmental investigation pending or, to the knowledge of LabOne, threatened
against LabOne, by or before any Governmental Authority or by any third party
which challenges the validity of this Agreement or which would be reasonably
likely to adversely affect or restrict LabOne's ability to consummate the
transactions contemplated hereby.

         SECTION 6.        ADDITIONAL COVENANTS AND AGREEMENTS.

         Each of the parties hereto shall comply with the following covenants
and agreements to the extent applicable to such party (unless compliance is
waived in advance in accordance with this Agreement):

         6.1      Access to Information.

                  (a)      All information concerning the ChoicePoint Entities
         or any Osborn Entity furnished or provided by the ChoicePoint Entities,
         the Osborn Entities or their representatives to LabOne or its
         representatives (whether furnished before or after the date hereof)
         shall be held subject to the confidentiality agreement by and between
         the Parent and LabOne, dated as of January 25, 2001 (the
         "Confidentiality Agreement").

                  (b)      LabOne agrees that it will maintain in a location
         reasonably convenient to the ChoicePoint Entities for at least seven
         (7) years after the date hereof (the "Tax/Accounting Retention
         Period"), the tax and accounting books, records, and documents (the
         "Tax/Accounting Records") of the Osborn Entities existing as of the
         date hereof. Notwithstanding the foregoing, in lieu of retaining any
         specific Tax/Accounting Records, LabOne may offer in writing to deliver
         such Tax/Accounting Records to the ChoicePoint Entities and, if such
         offer is not accepted within ninety (90) days, the offered
         Tax/Accounting Records may be destroyed or otherwise disposed of at any
         time. If the ChoicePoint Entities shall request in writing prior to the
         expiration of such 90-day period that any of Tax/Accounting Records
         proposed to be destroyed or disposed of be delivered to the ChoicePoint
         Entities, LabOne shall promptly arrange for delivery of such requested
         Tax/Accounting Records (at the ChoicePoint Entities' cost). Upon
         execution by ChoicePoint of a confidentiality agreement reasonably
         satisfactory to LabOne and

                                      -28-
<PAGE>

         ChoicePoint, LabOne shall afford the ChoicePoint Entities and their
         respective accountants, counsel, and representatives full access, for
         reasonable purposes, during normal business hours to Tax/Accounting
         Records at all times during the Tax/Accounting Retention Period.

                  (c)      LabOne agrees that it will maintain in a location
         reasonably convenient to the ChoicePoint Entities at least for the
         longer of (i) two (2) years after the date hereof or (ii) the period of
         time required by law (the "Non-Tax/Accounting Retention Period"), the
         books, records, and documents other than the tax and accounting books,
         records, and documents (the "Non-Tax/Accounting Records") of the Osborn
         Entities existing as of the date hereof. Notwithstanding the foregoing,
         in lieu of retaining any specific Non-Tax/Accounting Records, LabOne
         may offer in writing to deliver such Non-Tax/Accounting Records to the
         ChoicePoint Entities and, if such offer is not accepted within ninety
         (90) days, the offered Non-Tax/Accounting Records may be destroyed or
         otherwise disposed of at any time. If the ChoicePoint Entities shall
         request in writing prior to the expiration of such 90-day period that
         any of Non-Tax/Accounting Records proposed to be destroyed or disposed
         of be delivered to the ChoicePoint Entities, LabOne shall promptly
         arrange for delivery of such requested Non-Tax/Accounting Records (at
         the ChoicePoint Entities' cost). Upon execution by ChoicePoint of a
         confidentiality agreement reasonably satisfactory to LabOne and
         ChoicePoint, LabOne shall afford the ChoicePoint Entities and their
         respective accountants, counsel, and representatives full access, for
         reasonable purposes, during normal business hours to such books,
         records, and documents at all times during the Non-Tax/Accounting
         Retention Period.

         6.2      Consents. With respect to any agreements for which any
required consent or approval is not obtained prior to the date hereof, the
ChoicePoint Entities and LabOne shall each use their reasonable best efforts to
obtain any such consent or approval after the date hereof until such consent or
approval has been obtained.

         6.3      Fees and Expenses. The ChoicePoint Entities will be jointly
and severally obligated to pay all costs and expenses incurred by the Osborn
Entities or the ChoicePoint Entities in connection with the negotiation,
preparation, execution and delivery of this Agreement and the Ancillary
Agreements and the consummation of the transactions contemplated hereby and
thereby, including, without limitation, attorneys', accountants', brokers',
finders', and investment banking fees and expenses (collectively, "Expenses").
LabOne shall bear all such Expenses incurred by LabOne.

         6.4      Public Announcements. Upon execution of this Agreement, no
party shall make, or allow any Affiliate, agent or representative thereof to
make, any public announcements regarding this Agreement or the Ancillary
Agreements or the transactions contemplated hereby or thereby, including,
without limitation, any announcement to the financial community or to any
Governmental Authorities, employees, customers, suppliers or the general public,
without the prior written approval of the other party as to the content, timing
and manner of presentation or publication thereof; provided, however, that each
party may issue the press release agreed upon prior to the execution of this
Agreement and each party may make such other announcements and such other
disclosures as such party shall determine are required to be made by applicable
Law (including, without limitation, by the applicable rules of the New York
Stock Exchange or

                                      -29-

faith that any such disclosure is required by applicable Law, such party shall
nonetheless use its good faith efforts to consult (as to the content, timing and
manner of presentation or publication thereof) with the other party a reasonable
period of time prior to making such disclosure.

         6.5      Employees; Employee Benefits.

                  (a)      Except as provided below, nothing contained herein
         shall require LabOne to assume any Company Benefit Plans or accept the
         transfer of any assets or liabilities arising out of or associated with
         any Company Benefit Plans. All liabilities and obligations for retiree
         medical and life benefits payable on or after the date hereof to
         current retirees of the Osborn Entities, as determined on the date
         hereof, shall be paid by ChoicePoint.

                  (b)      As of the date hereof, LabOne or an Affiliate thereof
         shall continue the employment of the Employees listed on Schedule
         6.5(b)(i) (each such Employee who continues such employment being
         referred to individually herein as a "Transferred Employee" and all
         such Employees who continue such employment being referred to
         collectively herein as the "Transferred Employees"); provided, however,
         nothing contained herein shall be deemed to create an employment
         contract between LabOne and any Transferred Employee. Effective on the
         date hereof, pursuant to an employee secondment agreement mutually
         acceptable to the parties (the "Employee Secondment Agreement"), LabOne
         shall lease from CHS, for the transition period or periods contemplated
         by the Employee Secondment Agreement, the Employees listed on Schedule
         6.5(b)(ii) (the "Osborn Contract Employees"), and all Osborn Contract
         Employees shall become employees of CHS and shall remain eligible to
         participate in the Company Benefit Plans for the duration of the
         transition period.

                  (c)      ChoicePoint shall be solely responsible for
         terminating the Employees who are neither Transferred Employees nor
         Osborn Contract Employees ("Unaffected Employees"). ChoicePoint shall
         be solely responsible and assume liability for the termination of the
         Osborn Contract Employees and for all notices or payments due to any
         Unaffected Employees or Osborn Contract Employees prior to or
         subsequent to the date hereof, and all notices, payments, fines or
         assessments due to any Governmental Authority, pursuant to any
         applicable Law with respect to the employment, discharge, constructive
         discharge or layoff due to any Unaffected Employees or Osborn Contract
         Employees before or after the date hereof, including but not limited to
         the Workers Adjustment and Retraining Act (the "WARN Act") and the
         Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") and
         any rules or regulations that have been issued in connection with the
         foregoing.

                  (d)      For the period beginning on the date hereof and
         ending no earlier than December 31, 2001, LabOne shall, or shall cause
         the Osborn Entities to, provide each Transferred Employee and each
         Osborn Contract Employee who, subsequent to the transition period
         contemplated by the Employee Secondment Agreement, accepts an offer of
         employment with LabOne (collectively, the "Hired Employees") with
         compensation and benefits that are substantially comparable in the
         aggregate to the compensation and

                                      -30-
<PAGE>

         benefits provided to similarly situated LabOne employees. LabOne shall
         treat all service completed by a Hired Employee with any of the Osborn
         Entities or any Affiliate thereof, and any predecessor thereto, the
         same as service completed with LabOne for all purposes, including
         waiting periods relating to preexisting conditions under medical plans,
         vacations, severance pay, eligibility to participate in, vesting or
         payment of benefits under, and eligibility for early retirement or any
         subsidized benefit provided for under any employee benefit plan
         (including, but not limited to, any "employee benefit plan" as defined
         in Section 3(3) of ERISA) maintained by LabOne on or after the date
         hereof in which a Hired Employee participates, except for purposes of
         computing benefits under the accrued benefit formula in a pension plan
         (as defined in Section 3(2) of ERISA). Prior to the date hereof,
         ChoicePoint has furnished LabOne with a list of the length of service
         with the Osborn Entities or its Affiliates for each of the Employees.
         For purposes of computing deductible amounts (or like adjustments or
         limitations on coverage) under any employee welfare benefit plan
         (including, without limitation, any "employee welfare benefit plan" as
         defined in Section 3(l) of ERISA), expenses and claims previously
         recognized for similar purposes under the applicable welfare benefit
         plan of any of the Osborn Entities or any Affiliate shall be credited
         or recognized under the comparable plan maintained after the date
         hereof by LabOne.

                  (e)      After the date hereof, LabOne shall be responsible
         for, and shall indemnify and hold harmless ChoicePoint and its
         Affiliates and their officers, directors, employees, Affiliates and
         agents and the fiduciaries (including plan administrators) of the
         Company Benefit Plans, from and against, any and all claims, losses,
         damages, costs and expenses (including, without limitation, attorneys'
         fees and expenses) and other liabilities and obligations, with respect
         to the Transferred Employees, relating to or arising out of all
         salaries, bonuses, commissions, vacation entitlements and other

                  (a)      Acknowledgment. The ChoicePoint Entities acknowledges
         that the Osborn Entities conduct the Osborn Activities throughout the
         Territory and that, to protect adequately the interest of LabOne in the
         Business and goodwill of the Osborn Entities, it is essential that any
         noncompetition covenant with respect thereto cover all Osborn
         Activities and the entire Territory for the duration of the
         Noncompetition Period.

                  (b)      Trade Name. The ChoicePoint Entities hereby agree
         that, during the Noncompetition Period, neither of the ChoicePoint
         Entities nor any of their Affiliates will, directly or indirectly, own,
         manage, operate, join, control, or participate in the ownership,
         management, operation, or control of any business conducted under any

         LabOne.

                  (c)      Noncompetition Covenant. The ChoicePoint Entities
         hereby agree that neither of the ChoicePoint Entities nor any of their

         administrative, financial, or consulting nature) to any business that
         conducts any of Osborn Activities in the Territory. Notwithstanding
         anything in this Agreement to the contrary, each of the ChoicePoint
         Entities and their Affiliates may acquire up to two percent (2%) of any
         company whose common stock is publicly traded on a national securities
         exchange or in the over-the-counter market and may conduct the

         Entities"), the ChoicePoint Entities may wish to acquire an Acquired
         Entity or Acquired Entities that engage in the Osborn Activities as
         part of its business activities. The ChoicePoint Entities and LabOne
         acknowledge that nothing in this Agreement shall prevent the

         Entities during the Noncompetition Period that engage in the Osborn
         Activities, provided that the trailing twelve-month revenues derived
         from the Osborn Activities by the Acquired Entity or Acquired Entities,
         in the aggregate, do not exceed $30,000,000; provided, however, that,
         if, subsequent to the purchase of such Acquired Entity or Acquired
         Entities, the ChoicePoint Entities or their Affiliates receive and wish
         to accept a bona fide offer to dispose of the portion of the business
         of the Acquired Entity or Acquired Entities engaged in the Osborn
         Activities, the ChoicePoint Entities or their Affiliates, as the case
         may be, shall offer to sell to LabOne the portion of the business of
         the Acquired Entity or Acquired Entities engaged in the Osborn
         Activities at the price and under the terms offered by such bona fide
         offeror.

                  (d)      Nonsolicitation. The ChoicePoint Entities hereby

                  from any of the Osborn Entities' customers existing as of the
                  date hereof or during the one-year period prior to the date
                  hereof, for purposes of providing products or services that
                  are competitive with those provided by the Osborn Entities in
                  their conduct of the Osborn Activities; or

                           (ii)     hire, recruit, or solicit or attempt to
                  hire, recruit, or solicit, on behalf of any ChoicePoint Entity
                  or Affiliate thereof or on behalf of any other Person, firm,
                  or corporation, any employee or independent contractor of any
                  Osborn Entity, other than (A) those individuals listed on
                  Schedule 7.2(d)(ii), (B) any individual who is not hired by
                  LabOne or the Osborn Entities following the termination of the

                  hired by LabOne or the Osborn Entities but whose employment is
                  thereafter terminated by LabOne or the Osborn Entities;
                  provided, however, any individual covered by Section
                  7.2(d)(ii)(C) shall remain subject to any non-compete and
                  confidentiality agreements with LabOne.

         7.3      Severability. If a judicial or arbitral determination is made
that any of the provisions of this Agreement constitutes an unreasonable or
otherwise unenforceable restriction against the ChoicePoint Entities, the
provisions of this Agreement shall be rendered void only to the extent that such
judicial or arbitral determination finds such provisions to be unreasonable or
otherwise unenforceable with respect to the ChoicePoint Entities. In this
regard, the ChoicePoint Entities hereby agree that any Governmental Authority
construing this Agreement shall be empowered to sever any portion of the
Territory, any prohibited business activity or any time period from the coverage
of this Agreement, and to apply the provisions of this Agreement to the
remaining portion of the Territory, the remaining business activities, and the
remaining time period not so severed by such judicial or arbitral authority.

         Entity existing as of the date hereof; (ii) liabilities or obligations
         of any Osborn Entity in respect of guaranties entered into or letters
         of credit issued prior to the date hereof; (iii) the deferred purchase
         price of assets or services purchased prior to the date hereof which,
         in accordance with GAAP, should be shown on the liability side of a
         consolidated balance sheet of the Osborn Entities; (iv) any obligation
         of any Osborn Entity to pay a specified purchase price for goods or
         services whether or not delivered or accepted pursuant to any agreement
         entered into prior to the date hereof; or (v) liabilities or
         obligations of any Osborn Entity, as lessee, under any lease of
         property (whether real, personal or mixed) entered into prior to the
         date hereof which, in accordance with GAAP, should be shown as a
         capital lease on a consolidated balance sheet of the Osborn Entities;

                                      -38-

                  (e)      any claim, action, proceeding or investigation
         brought against any of the Osborn Entities prior to or after the date
         hereof based upon any event or omission occurring in respect of the
         assets, properties, activities or operations of the Osborn Entities
         prior to the date hereof;

                  (f)      any liability for or obligation to pay severance to
         any Unaffected Employee or Osborn Contract Employee; and

                  (g)      (i) all salaries, bonuses, commissions, vacation
         entitlements and other benefits or compensation earned or accrued prior
         to or after the Statement Date by any Unaffected Employee or any Osborn
         Contract Employee, (ii) all salaries, bonuses, commissions, vacation
         entitlements and other benefits or compensation earned or accrued prior
         to the Statement Date by any Transferred Employee, (iii) any
         liabilities or obligations in respect of any Company Benefit Plan, (iv)
         any claims of, or damages or penalties sought by, any Unaffected
         Employee or any Osborn Contract Employee with respect to any act or
         failure to act by any ChoicePoint Entity to the extent arising from the
         employment, discharge, layoff or termination of any such employee, (v)
         any liabilities under COBRA or the WARN Act as a result of the
         termination of any Unaffected Employee or Osborn Contract Employee and
         (vi) all liabilities and obligations for retiree medical and life
         benefits payable on and after the date hereof to current retirees of
         the Osborn Entities, as determined on the date hereof.

         For purposes of this Section 9, "Loss" or "Losses" shall mean any and
all claims, liabilities, obligations, losses (including any diminution in the
value of the Osborn Shares and the Osborn Canada Shares), costs, expenses,
penalties, fines, judgments, and damages whenever arising or incurred
(including, without limitation, amounts paid in settlement, costs of
investigation, and reasonable attorneys' and accountants' fees and expenses)
incurred by an Indemnified Party; provided, however, that an Indemnified Party
shall not be entitled to indemnification hereunder to the extent an accrual of
liability or a specific reserve for such matter is included in the Final Working
Capital Statement.

         9.3      Indemnification Obligations of LabOne. LabOne shall indemnify
and hold harmless each of the ChoicePoint Entities and their respective
officers, directors, employees, and Affiliates, and each of the heirs,
executors, successors, and assigns of any of the foregoing (collectively, the
"ChoicePoint Indemnified Parties") from, against, and in respect of any and all
Losses arising out of or relating to:

                  (a)      any breach or inaccuracy of any representation or
         warranty made by LabOne in Section 5; and

                  (b)      any breach of any covenant, agreement, or undertaking
         made by LabOne in this Agreement or any Ancillary Agreement.

         9.4      Indemnification Procedure.

                  (a)      Promptly after receipt by a LabOne Indemnified Party
         or a ChoicePoint Indemnified Party (hereinafter referred to as, the
         "Indemnified Party") of notice by a third party of any claim or the
         commencement of any action or proceeding with respect to

                                      -39-
<PAGE>

         which such Indemnified Party may be entitled to receive payment from
         the other party for any Losses (ignoring, for this purpose, the
         Threshold Amount (as hereinafter defined)), such Indemnified Party
         shall, within ten (10) days, notify LabOne or ChoicePoint, as the
         appropriate indemnifying party or representative thereof (the
         "Indemnifying Party"), of such third-party claim or of the commencement
         of such action or proceeding; provided, however, that the failure to so
         notify the Indemnifying Party shall not relieve the Indemnifying Party
         from liability for such third-party claim arising otherwise than under
         this Agreement and such failure to so notify the Indemnifying Party
         shall relieve the Indemnifying Party from liability under this
         Agreement with respect to such third-party claim only if, and only to
         the extent that, such failure to notify the Indemnifying Party results
         in the forfeiture by the Indemnifying Party of any rights or defenses
         otherwise available to the Indemnifying Party with respect to such
         third-party claim. Unless the Indemnifying Party is also a party to
         such third-party claim and the Indemnified Party determines in good
         faith after conferring with its outside counsel that joint
         representation would be inappropriate, the Indemnifying Party shall
         have the right, upon written notice delivered to the Indemnified Party
         within twenty (20) days thereafter (or, if earlier, by the tenth (10th)
         day preceding the day on which an answer or other pleading must be
         served in order to prevent judgment by default in favor of the Person
         asserting such claim), to assume the defense of such action or
         proceeding, including the employment of counsel reasonably satisfactory
         to the Indemnified Party and the payment of the fees and disbursements
         of such counsel. In the event, however, that the Indemnifying Party
         declines or fails to assume the defense of the action or proceeding or
         to employ counsel reasonably satisfactory to the Indemnified Party, in
         either case within such 20-day period (or earlier 10-day period, if
         applicable), then such Indemnified Party may employ counsel to
         represent or defend it in any such action or proceeding for the account
         and risk of the Indemnifying Party, and the Indemnifying Party shall
         pay the fees and disbursements of such counsel as incurred; provided,
         however, that the Indemnifying Party shall not be required to pay the
         fees and disbursements of more than one counsel for all Indemnified
         Parties in any jurisdiction in any single action or proceeding. In any
         action or proceeding with respect to which indemnification is being
         sought hereunder, the Indemnified Party or the Indemnifying Party,
         whichever is not assuming the defense of such action, shall have the
         right to participate in such litigation and to retain its own counsel
         at such party's own expense. The Indemnifying Party or the Indemnified
         Party, as the case may be, shall at all times use reasonable efforts to
         keep the Indemnifying Party or the Indemnified Party, as the case may
         be, reasonably apprised of the status of the defense of any action, the
         defense of which it is maintaining, and to cooperate in good faith with
         the other with respect to the defense of any such action. Anything in
         this Section 9.4 to the contrary notwithstanding, the Indemnifying
         Party shall not be entitled to assume the defense of any third-party
         claim (and shall pay the fees and expenses of counsel incurred by the
         Indemnified Party in defending such third-party claim as incurred) if
         the third-party claim seeks an injunction or other equitable relief or
         any other relief other than money damages against the Indemnified Party
         that the Indemnified Party reasonably determines, after conferring with
         its outside counsel, cannot be separated from any related claim for
         money damages.

                  (b)      If an Indemnifying Party assumes the defense of any
         third-party claim pursuant to paragraph (a) above, the Indemnifying
         Party may not, without the prior

                                      -40-
<PAGE>

         written consent of the Indemnified Party, settle or compromise such
         third claim or consent to the entry of any judgment in respect thereof
         unless (A) the sole relief provided to such third party is the payment
         of monetary damages which the Indemnifying Party pays or causes to be
         paid concurrently with the effectiveness thereof; (B) there is no
         finding or admission of any violation of Law or any violation of the
         rights of any Person and, in the good faith judgment of the Indemnified
         Party, no effect on any other claims that may be made against the
         Indemnified Party; and (C) the Indemnifying Party shall obtain, as a
         condition of such settlement, a complete unconditional release of the
         Indemnified Party. The Indemnified Party will have no liability with
         respect to any compromise or settlement of any third-party claim that
         is effected in violation of clause (ii) of the preceding sentence.

                  (c)      In the event any Indemnified Party should have a
         claim against any Indemnifying Party that does not involve a
         third-party claim being asserted against or sought to be collected from
         such Indemnified Party, the Indemnified Party shall deliver notice of
         such claim (together with a reasonably detailed description of the
         facts giving rise thereto, the provision of this Section 9 under which
         indemnification is being sought and the amount (or estimated amount) of
         Losses relating thereto) with reasonable promptness to the Indemnifying
         Party. The failure by any Indemnified Party so to notify the
         Indemnifying Party shall not relieve the Indemnifying Party from any
         liability that it may have to such Indemnified Party except to the
         extent that the Indemnifying Party demonstrates that it has been
         materially prejudiced by such failure. If the Indemnifying Party does
         not notify the Indemnified Party within twenty (20) days following its
         receipt of such notice that the Indemnifying Party disputes its
         liability to the Indemnified Party, such claim specified by the
         Indemnified Party in such notice shall be conclusively deemed a
         liability of the Indemnifying Party and the Indemnifying Party shall
         pay the amount of such liability to the Indemnified Party on demand or,
         in the case of any notice in which the amount of the claim (or any
         portion thereof) is estimated, on such later date when the amount of
         such claim (or such portion thereof) becomes finally determined. If the
         Indemnifying Party has timely disputed its liability with respect to
         such claim, as provided above, the Indemnifying Party shall promptly
         pay any amount of such claim that is not disputed and the Indemnifying
         Party and the Indemnified Party shall proceed in good faith to
         negotiate a resolution of such dispute and, if not resolved through
         negotiations, such dispute shall be resolved in accordance with Section
         11.12.

         9.5      Claims Period. For purposes of this Agreement, a "Claims
Period" shall be the period during which a claim for indemnification may be
asserted under this Agreement by an Indemnified Party, which period shall (a)
begin on the date hereof and (b) terminate as follows:

                   (i)      with respect to any Losses covered by Sections
                   9.2(a) or 9.3(a) hereof, the Claims Period shall terminate on
                   the date that is eighteen (18) months from the date hereof;
                   provided, however, the Claims Period shall (A) continue until
                   the expiration of any applicable statute of limitations
                   (giving effect to any extensions thereof) with respect to any
                   Losses resulting from any breach or inaccuracy of any
                   representation or warranty contained in Section 3.12 or
                   Section 3.14 hereof; and (B) the Claims Period shall continue
                   indefinitely with respect to any Losses resulting from any
                   breach or inaccuracy of any representation or

                                      -41-
<PAGE>
                  warranty contained in Section 3.1, 3.2, 3.4, 4.1, 4.2, 5.1 or
                  5.2 hereof; and

                           (ii)     with respect to any Losses covered by
                  Sections 9.2(b), 9.2(c), 9.2(d), 9.2(e), 9.2(f), 9.2(g) or
                  9.3(b) hereof, the Claims Period shall continue until
                  expiration of the applicable statute of limitations (after
                  giving effect to any extensions thereof).

         Notwithstanding the foregoing, if prior to the close of business on the
last day of the applicable Claims Period, an Indemnifying Party shall have been
properly notified of a claim for indemnity hereunder and such claim shall not
have been finally resolved or disposed of at such date, such claim shall
continue to survive and shall remain a basis for indemnity hereunder until such
claim is finally resolved or disposed of in accordance with the terms hereof.

         9.6      Threshold Amount; Limitation Amount. Notwithstanding anything
to the contrary set forth herein, the ChoicePoint Entities shall be liable for
Losses arising under Section 9.2(a) only to the extent that any such Losses
exceed, in the aggregate, $500,000 (the "Threshold Amount"), and such liability
shall be only for amounts which, in the aggregate, are in excess of the
Threshold Amount, and in no event shall the aggregate liability of the
ChoicePoint Entities under Section 9.2(a) exceed $9,750,000 (the "Limitation
Amount"). Notwithstanding the foregoing, Losses arising under or pursuant to any
matter constituting fraud or criminal activity under applicable Law by either of
the ChoicePoint Entities or, prior to the date hereof, any Osborn Entity shall
not be subject to the Threshold Amount or the Limitation Amount.

         9.7      Limitations on Indemnification. Notwithstanding anything
contained herein to the contrary:

                  (a)      The amount of Losses to which an Indemnified Party
         may be entitled to be indemnified against and reimbursed for under this
         Section 9 shall be (i) reduced by any indemnity or other recovery under
         any contract between an Indemnified Party and any third party and (ii)
         reduced by any insurance proceeds received by an Indemnified Party with
         respect to such Losses, (iii) reduced by any Tax benefits derived by an
         Indemnified Party as a result of such Losses; and (iv) increased by any
         Tax detriment suffered by an Indemnified Party as a result of its
         receipt of, or entitlement to, any indemnification payments including
         any increase in such payments pursuant to clause (iii). The parties
         shall cooperate with each other with respect to making claims under any
         contracts between an Indemnified Party and any third parties which
         agreements provide indemnification or similar rights for the benefit of
         the Indemnified Party. Such cooperation shall include making all
         reasonable claims and demands against any such third parties and
         pursuing such claims and demands in a commercially reasonable and
         timely manner.

                  (b)      If the Indemnifying Party makes any payment under
         this Section 9 with respect to any Losses, the Indemnifying Party shall
         be subrogated, to the extent of such payment, to the rights of the
         Indemnified Party against any insurer or other party with respect to
         such Losses, and the Indemnified Party shall assign to the Indemnifying
         Party any and all rights with respect to which and to the extent to
         which indemnification shall have been sought or made under this
         Agreement, and the Indemnified Party shall not take

                                      -42-
<PAGE>

         any action which directly or indirectly would affect such claims that
         the Indemnifying Party may have with respect thereto and shall
         cooperate in a timely and commercially reasonable manner with the
         Indemnifying Party in pursuing such claims.

                  (c)      Attorney, consultant, and other professional fees and
         disbursements incurred by an Indemnified Party in connection with this
         Section 9 shall be reasonable and based only on time actually spent
         which shall be charged at no more than such professional's standard
         hourly rate.

         9.8      Exclusive Remedy. Except as provided in Section 10 and Section
1.4, except to the extent a party may be entitled to the remedy of specific
performance, and except for a breach of any representation, warranty, or
covenant as a result of any matter constituting fraud or criminal activity under
applicable Law, the indemnification provisions of this Section 9 shall be the
exclusive remedy of the parties hereto against any other party under this
Agreement or otherwise with respect to Losses.

         SECTION 10.       TAX MATTERS.

         10.1     Preparation and Filing of Tax Returns. ChoicePoint will
prepare and timely file or will cause to be prepared and timely filed all
appropriate Federal, state, provincial, local and foreign Tax Returns in respect
of the Osborn Entities and their assets or activities that (a) are required to
be filed on or before the date hereof or (b) are required to be filed after the
date hereof and (i) are Consolidated Tax Returns or (ii) are with respect to
Income Taxes and are required to be filed on a separate Tax Return basis for any
Tax period ending on or before the date hereof. It is understood that any Income
Taxes attributable to (x) the distributions contemplated by Section 2 of this
Agreement or (y) any "deferred intercompany transaction" under Treasury
Regulation Section 1.1502-13 or 1.1502-14 or any transaction governed by a
similar provision that will be recognized as a result of the transactions
completed by this Agreement shall be reported on the Tax Returns described in
clause (b) of the foregoing sentence. It is further understood that any sales,
use, transfer or similar Taxes attributable to the distributions contemplated by
Section 2 of this Agreement shall be the sole responsibility of ChoicePoint and
that ChoicePoint shall be solely responsible for the preparation of any Tax
Returns relating to such Taxes. LabOne will prepare or cause to be prepared and
will timely file or cause to be timely filed all other Tax Returns required of
LabOne and its subsidiaries and Affiliates (including the Osborn Entities), or
in respect of their assets or activities. Any such Tax Returns that include
periods ending on or before the date hereof or that include the activities of
any of the Osborn Entities prior to the date hereof will be prepared with the
assistance of the ChoicePoint Entities, and will, insofar as they relate to the
Osborn Entities, be on a basis consistent with the last previous such Tax
Returns filed in respect of the Osborn Entities, unless ChoicePoint or LabOne,
as the case may be, concludes that there is no reasonable basis for such
position. Any reasonable out-of-pocket costs and expenses incurred in connection
with the preparation and filing of any Tax Return referred to in the preceding
sentence shall be borne by the ChoicePoint Entities and LabOne in proportion to
their responsibility for the Taxes reported on such Tax Return, whether or not
previously paid. None of LabOne or its Affiliates will file any amended Tax
Returns for any periods for or in respect of the Osborn Entities with respect to
which LabOne is not obligated to prepare or cause to be prepared the original
such Tax Returns pursuant to this Section 10.1 without the prior written consent
of ChoicePoint.

                                      -43-
<PAGE>

         10.2     Payment of Taxes.

                  (a)      The ChoicePoint Entities shall be jointly and
         severally obligated to timely pay or cause to be paid (a) all Income
         Taxes, and all Taxes shown as due other than Income Taxes, with respect
         to Tax Returns which ChoicePoint is obligated to prepare and file or
         cause to be prepared and filed pursuant to Section 10.1 and (b) all
         Taxes other than Income Taxes due on or before the date hereof for
         which no Tax Return is required to be filed. Subject to the ChoicePoint
         Entities' obligations described in Section 10.2(b) to pay LabOne an
         amount equal to the amount of any Taxes attributable to a Pre-Closing
         Tax Period, LabOne shall pay or cause to be paid (a) all Taxes shown as
         due with respect to any Tax Return for any taxable period that includes
         (but does not end on) the date hereof (a "Straddle Period") which
         LabOne is obligated to prepare and file or cause to be prepared and
         filed pursuant to Section 10.1 and (b) all Taxes owed by any of the
         Osborn Entities for all taxable periods beginning after the date
         hereof.

                  (b)      LabOne shall deliver to ChoicePoint copies of any
         Straddle Period Tax Return that LabOne is obligated to prepare and file
         or cause to be prepared and filed pursuant to Section 10.1 no later
         than ten (10) business days before filing for approval by ChoicePoint,
         which approval shall not be unreasonably withheld. Any such Tax Return
         shall be accompanied with a calculation by LabOne pursuant to the
         provisions of Section 10.7(b) of the amount of the Taxes shown on such
         Tax Return that are attributable to the Pre-Closing Tax Period, and
         that are therefore the joint and several responsibility of the
         ChoicePoint Entities. No later than three (3) business days prior to
         the due date of any such Straddle Period Tax Return, the ChoicePoint
         Entities shall be jointly and severally obligated to pay to LabOne an
         amount equal to the amount of such Taxes attributable to the
         Pre-Closing Tax Period pursuant to such calculation to the extent, if
         any, that such amount exceeds the sum of any estimated payments,
         deposits or credits made or applied prior to the date hereof and any
         amount reserved for tax liabilities on the Final Working Capital
         Statement with respect to the Taxes to which such Straddle Period Tax
         Return relates. In the event that ChoicePoint disagrees with such
         calculation, the ChoicePoint Entities shall not be relieved of their
         joint and several obligation to pay the amount resulting from such
         calculation, but may instead request that such calculation be reviewed
         by an independent accounting firm mutually agreeable to both
         ChoicePoint and LabOne. The decision of such independent accounting
         firm shall be final and binding upon the parties hereto, and the
         ChoicePoint Entities and LabOne shall each bear one-half of the fees
         and expenses of such accounting firm. LabOne shall pay to ChoicePoint
         the amount, if any, by which the sum of any estimated payments,
         deposits or credits made or applied prior to the date hereof with
         respect to such Tax for the Straddle Period exceeds the amount of such
         Taxes.

         10.3     Tax Sharing Agreements. On the date hereof, all Tax sharing
agreements and arrangements between (a) any of the Osborn Entities, on the one
side and (b) either of the ChoicePoint Entities or any of their subsidiaries or
Affiliates, on the other side, will be terminated and have no further effect for
any taxable year or period (whether a past, present or future year or period),
and no additional payments will be made thereunder on or after the date hereof
in respect of a re-determination of Tax liabilities or otherwise.

                                      -44-
<PAGE>

         10.4     Carryforwards and Carrybacks. LabOne will cause each of the
Osborn Entities to elect, where permitted by Law, to carry forward any net
operating loss, net capital loss, charitable contribution or other item arising
after the date hereof that could, in the absence of such an election, be carried
back to a taxable period of any of the Osborn Entities ending on or before the
date hereof in which any of the Osborn Entities were included in a Consolidated
Tax Return. LabOne, on its own behalf and on behalf of its Affiliates, hereby
waives any right to use or apply any net operating loss, net capital loss,
charitable contribution or other item of any Osborn Entity for any Tax year
ending on any date following the date hereof to any period of any Osborn Entity
ending on or before the date hereof with respect to which any of the Osborn
Entities was included in a Consolidated Tax Return.

         10.5     Refunds and Credits. ChoicePoint will be entitled to retain,
or receive immediate payment from LabOne or any of its subsidiaries or
Affiliates (including the Osborn Entities) of any refund or credit arising with
respect to any of the Osborn Entities (including, refunds and credits arising by
reason of amended Tax Returns filed after the date hereof or otherwise) relating
to Taxes with respect to any Tax period ending on or before the date hereof,
including, without limitation, any refund relating to Kansas income Taxes with
respect to the Tax period ending December 31, 1998; provided, however, that no
value shall be assigned to any such prospective refund or credit on the Final
Working Capital Statement. LabOne and the Osborn Entities will be entitled to
retain, or receive immediate payment from ChoicePoint of, any refund or credit
with respect to Taxes with respect to any taxable period beginning after the
date hereof relating to any of the Osborn Entities. LabOne and ChoicePoint will
equitably apportion any refund or credit with respect to Income Taxes with
respect to any Straddle Period. Notwithstanding any other provision of this
Section 10.5, ChoicePoint will be entitled to receive payment from LabOne of an
amount equal to the amount of any credit claimed by LabOne or its subsidiaries
(including the Osborn Entities) in any Tax Period beginning after the date
hereof that is attributable to any consolidated unused foreign tax which is paid
or accrued on or before the date hereof and attributed to any of the Osborn
Entities under Treas. Reg ss. 1.1502-79(d); provided, however, that no value
shall be assigned to any such foreign tax credit on the Final Working Capital
Statement.

         10.6     Tax Cooperation. Each of LabOne and ChoicePoint will provide
the other party with such information and records and make such of its
Representatives available as may reasonably be requested by such other party in
connection with the preparation of any Tax Return or any audit or other
proceeding that relates to any of the Osborn Entities.

         10.7     Tax Indemnification.

                  (a)      The ChoicePoint Entities will jointly and severally
         indemnify, defend and hold the LabOne Indemnified Parties harmless from
         and against (i) all liability for Taxes of the Osborn Entities for any
         taxable period that ends on or before the date hereof and the portion
         of any Straddle Period ending on the date hereof, (ii) all liability
         (as a result of Treas. Reg.ss.1.1502-6(a) or otherwise) for Income
         Taxes of any ChoicePoint Entity or any other Person (other than the
         Osborn Entities) which is or has ever been affiliated with any of the
         Osborn Entities, or with whom any of the Osborn Entities otherwise
         joins or has ever joined (or is or has ever been required to join) in
         filing any consolidated, combined or unitary Tax Return, prior to the
         date hereof, (iii) all liability for any breach

                                      -45-
<PAGE>

         of ChoicePoint's representations and warranties contained in Section
         3.12 or the ChoicePoint Entities' covenants contained in this Section
         10, (iv) all liability for any Taxes arising out of, or attributable to
         any of the distributions contemplated by Section 2 of this Agreement,
         and (v) all liability for reasonable legal, accounting and appraisal
         fees and expenses with respect to any item described in clause (i),
         (ii), (iii) or (iv) above; provided, however, that a LabOne Indemnified
         Party shall not be entitled to indemnification hereunder to the extent
         an accrual of liability or a specific reserve for such matter is
         included in the Final Working Capital Statement. Notwithstanding the
         foregoing, ChoicePoint will not indemnify, defend or hold harmless any
         member of the LabOne Indemnified Parties from any liability for Taxes
         attributable to any action taken on the date hereof by LabOne, any of
         its subsidiaries or Affiliates (including the Osborn Entities), or any
         transferee of LabOne or any of its subsidiaries or Affiliates (other
         than any such action taken in the ordinary course of business or
         expressly required or otherwise expressly contemplated by this
         Agreement) (a "LabOne Tax Act").

                  (b)      LabOne will indemnify, defend and hold the
         ChoicePoint Indemnified Parties harmless from and against (i) except to
         the extent any of the ChoicePoint Entities is otherwise required to
         indemnify LabOne for such Tax pursuant to Section 10.7(a), all
         liability for Taxes of each of the Osborn Entities for any taxable
         period beginning after the date hereof and the portion of any Straddle
         Period beginning after the date hereof, (ii) all liability for Taxes
         attributable to a LabOne Tax Act, (iii) all liability for Taxes
         attributable to an election by LabOne under section 338 of the Code
         with respect to the purchase of the Osborn Entities and (iv) all
         liability for reasonable legal, accounting and appraisal fees and
         expenses with respect to any item described in clause (i), (ii) or
         (iii) above.

                  (c)      The obligations of each party to indemnify, defend
         and hold harmless the other party or parties and other Persons,
         pursuant to Sections 10.7(a) and 10.7(b), will terminate upon the
         expiration of all applicable statutes of limitations (giving effect to
         any extensions thereof); provided, however, that such obligations to
         indemnify, defend and hold harmless will not terminate with respect to
         any individual item as to which an Indemnified Party shall have, before
         the expiration of the applicable period, previously made a claim by
         delivering a notice (stating in reasonable detail the basis of such
         claim) to the applicable Indemnifying Party.

                  (d)      In the case of any Straddle Period:

                           (i)      The periodic Taxes of each of the Osborn
                  Entities that are not based on income or receipts (e.g.,
                  property Taxes) for the portion of any Straddle Period ending
                  on the date hereof (the "Pre-Closing Tax Period") shall be
                  computed based on the ratio of the number of days in the
                  Pre-Closing Tax Period and the number of days in the entire
                  Tax period;

                           (ii)     Taxes of each of the Osborn Entities for the
                  Pre-Closing Tax Period (other than Taxes described in Section
                  10.7(d)(i) above) will be computed as if such taxable period
                  ended as of the close of business on the date hereof, and, in
                  the case of any Taxes of any of the Osborn Entities
                  attributable to the

                                      -46-
<PAGE>

                  ownership by any of the Osborn Entities of any equity interest
                  in any partnership or other "flowthrough" entity, as if a
                  taxable period of such partnership or other "flowthrough"
                  entity ended as of the close of business on the date hereof,
                  and, in each case, if such Taxes are Income Taxes, such Income
                  Taxes shall be computed by determining the items of income,
                  expense, deduction, loss or credit on a "closing of the books"
                  basis as of the end of the date hereof; and

                           (iii)    Income Taxes of each of the Osborn Entities
                  for which a Consolidated Tax Return is filed will be computed
                  in accordance with the principles of Treas. Reg.ss. 1.1502-76
                  as if separate returns had been filed for each of the Osborn
                  Entities for such Pre-Closing Tax Period and all prior taxable
                  periods.

                  (e)      Any indemnity payment required to be made pursuant to
         this Section 10.7 will be paid within thirty (30) days after the
         Indemnified Party makes written demand upon the Indemnifying Party, but
         in no case earlier than five (5) business days prior to the date on
         which the relevant Taxes are required to be paid (or would be required
         to be paid if no such Taxes are due) to the relevant taxing authority
         (including estimated Tax payments).

         10.8     Tax Contests.

                  (a)      If a claim is made by any taxing authority which, if
         successful, might result in an indemnity payment to any member of the
         LabOne Indemnified Parties or ChoicePoint Indemnified Parties pursuant
         to Section 10.7, the Indemnified Party will promptly notify the
         Indemnifying Party of such claim (a "Tax Claim"); provided, however,
         that the failure to give such notice will not affect the
         indemnification provided hereunder except to the extent the
         Indemnifying Party has actually been prejudiced as a result of such
         failure.

                  (b)      With respect to any Tax Claim relating to Taxes and
         relating to a taxable period ending on or before the date hereof or to
         any other taxable period in which any of the Osborn Entities joined in
         filing any Consolidated Tax Return, ChoicePoint will control all
         proceedings and may make all decisions in connection with such Tax
         Claim (including selection of counsel) and, without limiting the
         foregoing, may in its sole discretion pursue or forego any and all
         administrative appeals, proceedings, hearings and conferences with any
         taxing authority with respect thereto, and may, in its sole discretion,
         either pay the Tax claimed and sue for a refund where applicable Law
         permits such refund suits or contest the Tax Claim in any permissible
         manner. LabOne will control all proceedings and may make all decisions
         in connection with any Tax Claim other than a Tax Claim described in
         the first sentence of this Section 10.8(b) or a Tax Claim described in
         Section 10.8(c) (including selection of counsel).

                  (c)      ChoicePoint and LabOne will jointly control and
         participate in all proceedings taken in connection with any Tax Claim
         relating to Taxes of any of the Osborn Entities for any Straddle
         Period. Neither ChoicePoint nor LabOne will settle any

                                      -47-
<PAGE>

         such Tax Claim without the prior written consent of the other (which
         consent shall not be unreasonably withheld).

                  (d)      Each of LabOne, the Osborn Entities and their
         respective Affiliates, on the one hand, and the ChoicePoint Entities
         and their respective Affiliates, on the other, will cooperate in
         contesting any Tax Claim, which cooperation will include the retention
         and (upon request) the provision to the requesting party of records and
         information which are reasonably relevant to such Tax Claim, and making
         employees available on a mutually convenient basis to provide
         additional information or explanation of any material provided
         hereunder or to testify at proceedings relating to such Tax Claim.

         10.9     Definitions. As used in this Agreement:

                  (a)      "Consolidated Tax Returns" means Tax Returns which
         include the Osborn Entities, on the one hand, and the ChoicePoint
         Entities or any of their subsidiaries or Affiliates (other than the
         Osborn Entities), on the other hand; and

                  (b)      "Income Taxes" means all Taxes based upon, measured
         by, or calculated with respect to (a) net income or profits (including
         any capital gains, minimum taxes and any Taxes on items of tax
         preference, but not including sales, use, real property gains, real or
         personal property, gross or net receipts, transfer or other similar
         Taxes) or (b) multiple bases (including corporate franchise, doing
         business or occupation Taxes) if one or more of the bases upon which
         such Tax may be based upon, measured by, or calculated with respect to
         is described in clause (a) of this definition.

         after reasonable investigation, of Douglas C. Curling, Michael S. Wood,
         J. Michael de Janes, Dan H. Rocco, Gilbert P. Bourk, Roger A. Lewis,

be governed by and construed and enforced in accordance with the internal Laws
of the State of Delaware without reference to Delaware choice of law rules. This
Agreement, together with the Ancillary Agreements, constitute the entire
agreement among the parties hereto and supersede all prior written and oral
agreements between the parties with respect to the subject matter hereof;
provided, however, the Confidentiality Agreement shall remain in full force and
effect after the date hereof. This Agreement may not be amended, modified, or
supplemented except by written agreement of LabOne and the Parent and no
provision hereof shall be deemed to have been waived by any party hereto unless
such waiver is in writing and signed by the party against whom enforcement is
sought. It is understood and agreed by the parties that no failure or delay by
any party in exercising any right, power or privilege hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise thereof preclude any
other or future exercise thereof or the exercise of any other right, power or
privilege hereunder. Except as provided in the preceding sentence, no action
taken pursuant to this Agreement, including without limitation any investigation
by or on behalf of any party, shall be deemed to constitute a waiver by the
party taking such action of compliance with any representations, warranties,
covenants or agreements contained in this Agreement. No provision of this
Agreement shall be construed against or interpreted to the disadvantage of any
party hereto by any court or other Governmental Authority or by any board of
arbitrators by reason of such party or its counsel having or being deemed to
have structured or drafted such provision.

         11.8     Severability. Any provision hereof which is prohibited or
unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition

                                      -50-
<PAGE>

or unenforceability in any jurisdiction will not invalidate or render
unenforceable such provision in any other jurisdiction. To the extent permitted
by Law, the parties hereto waive any provision of Law which renders any such
provision prohibited or unenforceable in any respect.

         11.9     Counterparts. This Agreement may be executed in counterparts
each of which shall be deemed an original and all of which together shall
constitute one and the same agreement.

         11.10    Enforcement of Certain Rights. Nothing expressed or implied in
this Agreement is intended, or shall be construed, to confer upon or give any
Person other than the parties hereto, and their successors or permitted assigns,
any rights, remedies, obligations, or liabilities under or by reason of this
Agreement, or result in such Person being deemed a third-party beneficiary of
this Agreement.

         11.11    Injunctive Relief. Each of the parties hereby agrees that any
remedy at law for any breach of any provision contained this Agreement shall be
inadequate and that a party shall be entitled to seek injunctive relief, without
proof of actual damages or the necessity of posting bond, in addition to any
other remedy such party might have under this Agreement.

         11.12    Submission to Jurisdiction. Each of the parties hereto agrees
that any suit, action or proceeding arising out of or relating to this Agreement
or the Ancillary Agreements, their subject matter, the performance by the
parties of their respective obligations with respect to this Agreement and the
Ancillary Agreements or the claimed breach thereof, whether brought at law or in
equity and whether based in tort, contract or otherwise, or for recognition and
enforcement of any judgment in respect thereof, shall be brought by any of such
parties or any of their respective successors or permitted assigns in any
federal or state court located in the County of New Castle, Delaware, and each
of such parties hereby submits with regard to any such suit, action or
proceeding for itself and in respect to its property, generally and
unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of
the parties hereto hereby irrevocably waives, and agrees not to assert, by way
of motion, as a defense, counterclaim or otherwise, in any such suit, action or
proceeding (a) any claim that it is not personally subject to the jurisdiction
of such courts for any reason other than the failure to lawfully serve process,
(b) that it or its property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment prior to judgment, attachment in aid of execution
of judgment, execution of judgment or otherwise), (c) that the suit, action or
proceeding in any such court is brought in an inconvenient forum, (d) that the
venue of such suit, action or proceeding is improper, (e) that this Agreement or
any Ancillary Agreement or the subject matter hereof or thereof may not be
enforced in or by such courts or (f) any right to a trial by jury. Each of the
parties hereto irrevocably consents to the service of process in any such
proceeding by the mailing of copies thereof by certified mail, postage prepaid,
to such party's address for notices under this Agreement.

EXHIBIT 10.1 - CHANGE IN CONTROL AGREEMENT, DATED SEPTEMBER 18, 2001, BETWEEN
COMMUNITY BANCSHARES, INC. AND KERRI C. NEWTON

                           CHANGE IN CONTROL AGREEMENT

         THIS CHANGE IN CONTROL AGREEMENT (this "Agreement"), dated this 18th
day of September, 2001, by and between Community Bancshares, Inc. a Delaware
corporation (the "Company"), and Kerri C. Newton (the Executive").

                                   WITNESSETH:

         WHEREAS, the Company wishes to assure itself and its key employees of
continuity of management and objective judgment in the event of any actual or
contemplated Change in Control of the Company, and the Executive is a key
employee of the Company or one of its subsidiaries and is an integral part of
management of the Company (for purposes hereof employment with any present or
future parent or subsidiary corporation of the Company shall be considered
employment by the Company); and

         WHEREAS, this Agreement is not intended to materially alter the
compensation and benefits that the Executive could reasonably expect to receive
in the absence of a Change in Control of the Company, and this Agreement
accordingly will be operative only upon circumstances relating to an actual or
anticipated change in control of the Company.

         NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants herein contained, the parties hereby agree as follows:

         I.       OPERATION OF AGREEMENT

         This Agreement shall be effective immediately upon its execution by the
parties hereto, but anything in this Agreement to the contrary notwithstanding,
neither the Agreement nor any provision hereof shall be operative unless, during
the term of this Agreement, there has been a Change in Control of the Company
during the term of this Agreement, all of the provisions hereof shall become
operative immediately.

         II.      TERM OF AGREEMENT

         The term of this Agreement shall be for an initial three (3) year
period commencing on the date hereof; provided however that this Agreement shall
be extended automatically for one (1) additional year at the end of this initial
term and at the end of each additional year thereafter, unless the Compensation
Committee delivers written notice twelve (12) months prior to the end of such
term, or extended term, to the Executive, that the Agreement will not be
extended. In such case, the Agreement will terminate at the end of the term, or
extended term, then in progress.

         However, in the event a Change in Control occurs during the original or
any extended term, this Agreement will remain in effect until all obligations of
the Company hereunder have been fulfilled, and until all benefits required
hereunder have been paid to the Executive.

                  (iii) consummation of (a) a merger, consolidation or other

         is not covered by (i) through (iii) above which the Board determines
         affects control of the Company and, in order to implement the purposes
         of this Agreement as set forth above, adopts a resolution that such
         event or circumstance constitutes a Change in Control for the purposes
         of this Agreement.

IV.      BENEFITS UPON TERMINATION FOLLOWING A CHANGE IN CONTROL

         1.       TERMINATION - The Executive shall be entitled to, and the
         Company shall pay or provide to the Executive, the benefits described
         in Section 2 below if (a) a Change in Control occurs during the term of
         this Agreement, and (b) the Executive's employment is terminated within
         thirty (30) months following the Change in Control either (i) by the
         Company (other than for Cause or by reason of the Executive's
         Retirement, death or Disability) or (ii) by the Executive pursuant to
         Involuntary Termination; provided, however, that if:

         (a)      during the term of this Agreement there is a public
         announcement of a proposal for a transaction that, if consummated,
         would constitute a Change in Control or the Board receives and decides
         to explore an expression of interest with respect to a transaction
         which, if consummated, would lead to a Change in Control (either
         transaction being referred to herein as the "Proposed Transaction");
         and

         (b)      the Executive's employment is thereafter terminated by the
         Company other than for Cause or by reason of the Executive's
         Retirement, death or Disability; and

         (c)      the Proposed Transaction is consummated within one (1) year
         after the date of termination of the Executive's employment.

         then, for the purposes of this Agreement, a Change in Control shall be
         deemed to have occurred during the term of this Agreement and the
         termination of the Executive's employment shall be deemed to have
         occurred within thirty (30) months following a Change in Control.

         The executive shall also be entitled to receive the benefits described
         in Section 2 below if he terminates employment for any reason during a
         30-day period beginning twelve months after the occurrence of a Change
         in Control.

         2.       BENEFITS TO BE PROVIDED - If the Executive becomes eligible
for benefits under Section 1 above, the Company shall pay or provide to the
Executive the benefits set forth in this Section 2.

         (a)      SALARY - The Executive will continue to receive his current
salary (subject to withholding of all applicable taxes and any amounts referred
to in Section 2(c) below) for a period of thirty (30) months from his date of
termination in the same manner as it was being paid as of the date of
termination; provided, however, that the salary payments provided for hereunder
shall be paid in a single lump sum payment, to be paid not later than thirty
(30) days after his termination of employment; provided further, that the amount
of such lump sum payment shall be determined by taking the salary payments to be
made and discounting them to their Present Value. For purposes hereof, the
Executive's "current salary" shall be the highest rate in effect during the
six-month period prior to the Executive's termination.

         (b)      BONUSES - The Executive shall receive payments from the
Company for the thirty (30) months following the month in which this employment
is terminated in an amount for each such month equal to one-twelfth of the
average of the bonuses earned by her for the two calendar years immediately
preceding the year in which such termination occurs. Any bonus amounts that the
Executive had previously earned from the Company but which may not yet have been
paid as of the date of termination shall not be affected by this provision,
other than to serve as a measurement for this portion of the

<PAGE>

severance benefit. The bonus amounts determined herein shall be paid in a single
lump sum payment, to be paid not later than 30 days after termination of
employment; provided, further, that the amount of such lump sum payment shall be
determined by taking the bonus payments (as of the payment date) to be made and
discounting them to their Present Value.

         (c)      HEALTH AND LIFE INSURANCE COVERAGE - The health and life
insurance benefits coverage provided to the Executive at his date of termination
shall be continued at the same level and in the same manner as if his employment
had not terminated (subject to the customary changes in such coverages if the
Executive retires or reaches age 65 or similar events), beginning on the date of
such termination and ending on the date thirty (30) months from the date of such
termination. Any additional coverages the Executive had at termination,
including dependent coverage, will also be continued for such period at the same
level and on the same terms as provided to the Executive immediately prior to
his termination, to the extent permitted by the applicable policies or contract.
Any costs Executive was paying for such coverages at the time of termination
shall be paid by the Executive by separate check payable to the Company each
month in advance. If the terms of any benefit plan referred to in this Section
do not permit continued participation by the Executive, then the Company will
arrange for other coverage at its expense providing substantially similar
benefits as it can find for other officers in similar positions.

         (d)      EMPLOYEE RETIREMENT PLANS - To the extent permitted by the
applicable plan, the Executive will be fully vested in and will be entitled to
continue to participate, consistent with past practices, in all employee
retirement plans maintained by the Company in effect as of his date of
termination. The Executive's participation in such retirement plans shall
continue for a period of thirty (30) months from the date of termination of his
employment (at which point he will be considered to have terminated employment
within the meaning of the plans) and the compensation payable to the executive
under (a) and (b) above shall be treated (unless otherwise excluded) as
compensation under the plan. If full vesting and continued participation in any
plan is not permitted, the Company shall pay to the executive and, if
applicable, his beneficiary, a supplemental benefit equal to the Present Value
on the date of termination of employment of the excess of (i) the benefit the
Executive would have been paid under such plan if she had been fully vested and
had continued to be covered for the 30-month period as if the Executive had
earned compensation described under (a) and (b) above and had made contributions
sufficient to earn the maximum matching contribution, if any, under such plan
(less any amounts she would have been required to contribute), over (ii) the
benefit actually payable to or on behalf of the Executive under such plan. For
purposes of determining the benefit under (i) in the preceding sentence,
contributions deemed to be made under a defined contribution plan will be deemed
to be invested in the same manner as the Executive's account under such plan at
the time of termination of employment. The Company shall pay such supplemental
benefits (if any) in a lump sum.

         (e)      CAREER COUNSELING - The Company will provide career counseling
and out placement services on an individual basis to the Executive as the
Company deems appropriate and for a reasonable period following the Executive's
termination of employment; provided, however, that the Company's obligation to
provide such services shall terminate at such time, if any, as the cost of such
services exceeds $5,000.

         (f)      EFFECT OF LUMP SUM PAYMENT - The lump sum payment under (a) or
(b) above shall not alter the amounts the Executive is entitled to receive under
the benefit plans described in (c) and (d) above. Benefits under such plans
shall be determined as if the Executive had remained employed and received such
payments over a period of thirty (30) months.

         (g)      EFFECT OF DEATH OR RETIREMENT - The benefits payable or to be
provided under this

<PAGE>

Agreement shall continue in the event of the Executive's death and shall be
payable to his estate or named beneficiary. The benefits payable or to be
provided under this Agreement shall cease in the event of the Executive's
election to commence Retirement benefits under the Company's retirement plan.

         (h)      TOTAL BENEFIT - Notwithstanding anything in this Agreement to
the contrary, the Total Benefit payable or to be provided to the Executive by
the Company or an affiliate, whether pursuant to this Agreement or otherwise,
shall be calculated so as to provide the greatest total benefit to the Executive
after taxes. The Company shall calculate, or authorize an independent third
party to calculate, the Executive=s Total Benefit under three different methods
and make payment to the Executive according to the method that provides the
Executive with the greatest total benefit after taxes.

         (i)      TOTAL BENEFIT CALCULATION - The three methods of benefit
calculation shall include the Limited Benefit Method, the Unlimited Benefit
Method and the Grossed Up Unlimited Benefit Method, as each is defined herein.
Under the Limited Benefit Method, the Executive=s Total Benefit shall be
determined as defined in this Section IV and then modified or reduced to the
extent necessary so that the benefits payable or to be provided to the Executive
under this Agreement that are treated as Severance Payments, as well as any
payments or benefits provided outside of this Agreement that are so treated,
shall not cause the Company to have paid an Excess Severance Payment. In
computing such amount, the parties shall take into account all provisions of
Internal Revenue Code Section 280G, including making appropriate adjustments to
such calculation for amounts established to be Reasonable Compensation. In the
event that the amount of any Severance Payments that would be payable to or for
the benefit of the Executive under this Agreement must be modified or reduced,
the Executive shall direct which Severance Payments are to be modified or
reduced; provided, however, that no increase in the amount of any payment or
change in the timing of the payment shall be made without the consent of the
Company. The Limited Benefit Method shall be interpreted so as to avoid the
imposition of excise taxes on the Executive under Section 4999 of the Code or
the disallowance of a deduction to the Company pursuant to Section 280G(a) of
the Code with respect to amounts payable under this Agreement or otherwise. The
Executive shall be responsible for any and all federal and state income taxes
associated with the Limited Benefit Method. Under the Unlimited Benefit Method,
the Total Benefit payable to the Executive shall be determined as defined in
this Section IV and shall not be reduced or modified in any manner. The
Executive shall be responsible for any and all income, excise and/or other taxes
associated with the Unlimited Benefit Method. Under the Grossed Up Unlimited
Benefit Method, the Executive=s Total Benefit shall be determined as defined in
this Section IV with no reduction, and an additional payment shall be made to
the Executive by the Company with such additional payment equal to the amount of
any excise tax on the Total Benefit plus the estimated federal and state income
taxes and any excise tax associated with the additional payment.

         (j)      NO OBLIGATION TO FUND - The agreement of the Company (or its
successor) to make payments to the Executive hereunder shall represent solely
the unsecured obligation of the Company (and its successor), except to the
extent the Company (or its successors) in its sole discretion elects in whole or
in part to fund its obligations under this Agreement pursuant to a trust
arrangement or otherwise.

         V.       MISCELLANEOUS

         1.       CONTRACT NON-ASSIGNABLE - The parties acknowledge that this
Agreement has been entered into due to, among other things, the special skills
of the Executive, and agree that this Agreement may not be assigned or
transferred by the Executive, in whole or in part, without the prior written
consent of the Company. Any business entity succeeding to all or substantially
all of the business of the Company by purchase, merger, consolidation, sale of
assets or otherwise, shall be bound by this Agreement.

<PAGE>

         2.       OTHER AGENTS - Nothing in this Agreement is to be interpreted
as limiting the Company from employing other personnel on such terms and
conditions as may be satisfactory to the Company.

         3.       NOTICES - All notices, requests, demands and other
communications required or permitted hereunder shall be in writing and shall be

         4.       PROVISIONS SEVERABLE - If any provision or covenant, or any
part thereof, of this Agreement should be held by any court to be invalid,
illegal or unenforceable, either in whole or in part, such invalidity,
illegality or unenforceability shall not affect the validity, legality or
enforceability of the remaining provisions or covenants, or any part thereof, of
this Agreement, all of which shall remain in full force and effect.

         5.       WAIVER - Failure of either party to insist, in one or more
instances, on performance by the other in strict accordance with the terms and
conditions of this Agreement shall not be deemed a waiver or relinquishment of
any right granted in this Agreement or of the future performance of any such
term or condition or of any other term or condition of this Agreement, unless
such waiver is contained in a writing signed by the party making the waiver.

         6.       AMENDMENTS AND MODIFICATIONS - This Agreement may be amended

disputes that may arise between them relating to the interpretation or
performance of this Agreement, including matters relating to any funding
arrangements for the benefits provided under this Agreement, shall be determined
by binding arbitration through an arbitrator approved by the American
Arbitration Association or other arbitrator mutually acceptable to the parties.
The award of the arbitrator shall be final and binding upon the parties and
judgment upon the award rendered may be entered in any court having
jurisdiction. In the event the Executive incurs legal fees and other expenses in
seeking to obtain or to enforce any such rights or benefits through settlement,
arbitration or otherwise, the Company shall promptly pay the Executive's
reasonable legal fees and expenses incurred in enforcing this Agreement.

         9.       INDEMNITY - The Executive shall be entitled to the benefits of
the indemnity currently applicable to the Executive, if any, as provided by the
Company's articles of incorporation or bylaws. Any changes to the articles of
incorporation or bylaws reducing the indemnity granted to officers shall not
affect the rights granted hereunder. The Company may not reduce these indemnity
benefits confirmed to the Executive hereunder without the written consent of the
Executive.

         10.      TERMINATION OF PRIOR AGREEMENTS - The Executive hereby agrees
to a mutual termination, effective as of the effective date of this Agreement,
of any prior existing change in control agreements (by whatever name), providing
benefits to the Executive upon a termination of employment following a Change in
Control of the Company, to which she and the Company are parties, and as to such
prior agreements, if any, the Executive releases all claims, rights and
entitlements.

         11.      REGULATORY APPROVALS - The Agreement, and the rights and
obligations of the parties hereto, shall be subject to approval of the same by
any and all regulatory authorities having jurisdiction over the Company, to the
extent such approval is required by law, regulation, or order.

         12.      REGULATOR INTERVENTION - Notwithstanding any term of this
Agreement to the contrary, this Agreement is subject to the following terms and
conditions:

         (a)      The Company's obligations to provide compensation or other
benefits to Executive under this Agreement may be suspended if the Company has
been served with a notice of charges by the

<PAGE>

appropriate federal banking agency under provisions of Section 8 of the Federal
Deposit Insurance Act (12 U.S.C. 1818) directing the Company to cease making
payments required hereunder; provided, however, that

                  (I)      The Company shall seek in good faith with its best
         efforts to oppose such notice of charges as to which there are
         reasonable defenses;

                  (ii)     In the event the notice of charges is dismissed or
         otherwise resolved in a manner that will permit the Company to resume
         its obligations to provide compensation or other benefits hereunder,
         the Company shall immediately resume such payments and shall also pay
         Executive the compensation withheld while the contract obligations were
         suspended, except to the extent precluded by such notice; and

                  (iii)    During the period of suspension, the vested rights of
         the contracting parties shall not be affected, except to the extent
         precluded by such notice.

         (b)      The Company's obligations to provide compensation or other
benefits to Executive under this Agreement shall be terminated to the extent a
final order has been entered by the appropriate federal banking agency under
provisions of Section 8 of the Federal Deposit Insurance Act (12 U.S.C. 1818)
directing the Company not to make the payments required hereunder; provided,
however, that the vested rights of the contracting parties shall not be affected
by such order, except to the extent precluded by such order.

         (c)      The Company's obligations to provide compensation or other
benefits to Executive under this Agreement shall be terminated or limited to the
extent required by the provisions of any final regulation or order of the
Federal Deposit Insurance Company promulgated under Section 18(k) of the Federal
Deposit Insurance Act (12 U.S.C. 1828(k)) limiting or prohibiting any "golden
parachute payment" as defined therein, but only to the extent that the
