2.   INSURANCE

The Company's agreement under the Policies to insure the Employer's Employees is

     (a)  Benefit Payments Paid during Policy Continuance. The Company shall pay
          from the claims account established as provided in section 2(d) below
          (the "Claims Account") those Health Benefits of the Policies that are
          Paid during the Arrangement Month and that in the aggregate are equal
          to or less than the Maximum Monthly Employer Benefit Obligation for
          the Arrangement Month. The Employer shall fund that Claims Account as
          provided in section 2(d) of the Agreement. For Health Benefits that
          are Paid prior to termination of the Policies, the Company shall pay
          from its own funds those Health Benefits that are Paid during an
          Arrangement Month to the extent that they exceed the Maximum Monthly
          Employer Benefit Obligation for the Arrangement Month.

     (b)  Benefits Paid After Policy Termination. In the event that a Policy is
          terminated, the Company shall be responsible for paying from its own
          funds Health Benefits of such Policy that are Incurred but not Paid
          before such Policy terminates. The Maximum Monthly Employer Benefit
          Obligation does not apply to such Health Benefits.

     (c)  Company's Obligation. Any Health Benefits of the Policies that are
          required to be paid from the Claims Account shall be paid by the
          Company from its own funds if the Health Benefits are not paid by
          another source, which may include the Employer or another funding
          vehicle established or maintained by the Employer for that purpose.
          The Employer agrees to reimburse the Company for any Health Benefits
          paid by the Company pursuant to this obligation.

     (d)  Claims Account. The Company and the Employer shall establish and
          maintain those banking arrangements, including the Claims Account,
          described in Exhibit C to the Agreement.

                                       7
<PAGE>

          In addition to its obligations under Exhibit C, the Employer shall
          fund the Claims Account as necessary to enable the Company to pay in a
          timely manner from the Claims Account the Health Benefits described in
          section 2(a).

          (i)  If the Employer does not maintain the banking arrangements
               required in this section or in Exhibit C, including any required
               balance, the Company will provide notice to the Employer so that
               it can take corrective action, and the Company may terminate the
               Agreement in accordance with section 4 of the Agreement.

          (ii) After a reasonable period of time as determined by the Company,
               the Company shall place stop payment instructions on Checks
               issued pursuant to the Agreement that are not Paid. The Company
               shall be responsible for complying with applicable abandoned
               property laws, if any, with respect to any Checks that are not
               Paid prior to the termination of the Agreement. Any amount
               transferred to a state in compliance with such laws shall be
               treated as Paid on the date that the transfer is made.

          (iii) Upon termination of the Agreement, the Claims Account shall be
                closed as soon as reasonably practicable after the Company
                determines that all Health Benefits required to be Paid from the
                Claims Account have been Paid, and any funds remaining in the
                Claims Account shall be recovered by the Employer, subject to
                the Company's right to offset such funds against amounts owed
                to it under the Minimum Premium Arrangement.

3.   PREMIUM

The amount of premium to be paid by the Employer to the Company for insurance of
the Health Benefits payable under the Policies, as modified by the Agreement, is
changed to be equal to the sum of (a) the MP Premium, and (b) the ***. All of
the provisions of each Policy that apply to "premium" for Health Benefits of the
Policy apply to the MP Premium and the ***.

          Premium may include any adjustments authorized in Exhibit E of the MP
          Administrative Services Agreement in respect of previous Arrangement
          Months including any additions, terminations or changes in coverage
          not known at the beginning of the Arrangement Month to which such MP
          Premium applies.

     (b)  Additional Quarterly Premium. For each Arrangement Quarter, the
          Employer shall pay an Additional Quarterly Premium to the Company in
          an amount equal to ***, before the *** of the Agreement for the
          Arrangement Months in such Arrangement Quarter less the Health
          Benefits Paid by the Company from the Claims Account in such
          Arrangement Quarter. Such invoice shall be sent by the Company no
          later than *** months following the close of the Policy Year which
          includes the Arrangement Quarter to which such invoice relates. An
          Additional Quarterly Premium shall not be due with respect to any
          Arrangement Quarter in a Policy Year if a written invoice for such
          Additional Quarterly Premium is not sent by the Company to the
          Employer within *** months of the close of the Policy Year; provided
          that the Company shall not have been prevented by the Employer from
          exercising its right to audit the Employer as provided in section 5(c)
          of the MP Administrative Services Agreement. The Additional Quarterly
          Premium shall be paid by the Employer within *** calendar days of the
          date of the Company's invoice and *** provided in any Policy shall be

          ii.  Either party may elect to terminate the Agreement as of the last
               day of an Arrangement Quarter by giving written notice to the

               other party, if notice of the breach is provided by the

                        date of closing of the sale is less than the amount then
                        required under the Security Deposit Agreement; or

                  (E)   As used in clause (A) above, an "affiliate" of an entity
                        is an organization or entity which controls, is
                        controlled by or is under common control with the entity
                        to which it is an affiliate. "Control" for this purpose
                        refers to the ownership of more than 50% of the voting
                        power of an entity.

            ix.   Except as provided in paragraph (B) below, the Employer may
                  terminate this Agreement by giving the Company notice thereof
                  not more than *** business days following receipt from the
                  Company of notice of an *** of more than *** percentage points
                  in the percentage of the *** used to calculate the MP Premium.
                  (For example, if the percentage of the *** used to calculate
                  the MP Premium equals ***, the Company may *** such percentage
                  by *** percentage points to *** without triggering the
                  Employer's termination right under this clause ix.)

                  (A)   Any such termination shall be effective on the date set
                        forth in the Employer's notice to the Company, but in
                        any event not sooner than the date the applicable ***
                        would otherwise be effective.

                  (B)   The Employer shall not have the right to terminate the
                        Agreement pursuant to this section 4(b)(ix) if the
                        increase in the percentage of the Quoted Premium used to
                        calculate the MP Premium is pursuant to section 4(c) or
                        due to the imposition of any premium tax not included in
                        the Quoted Premium at the time that the imposition was
                        effected.

      (c)   The Policies shall terminate upon termination of the Agreement. If
            one or more of the Policies may not, by its terms, be terminated as
            of the date that the Agreement would otherwise terminate, the
            Agreement shall be terminated notwithstanding the inability to
            terminate a Policy as of the

                                       12
<PAGE>

            same date, and the terms of the Policy shall remain in force,
            unmodified by the Agreement, until such Policy can be terminated.
            However, effective as of the date of the termination of the
            Agreement, the monthly premium due under each such Policy and Non-MP
            Policy shall automatically be increased ("Increased Premium") such
            that the sum of (i) the aggregate Increased Premiums due under such
            Policies and Non-MP Policies through their termination dates and
            (ii) the balance in the Security Deposit following the withdrawal
            described in section 4(a) of the Security Deposit Agreement, equals
            *** of the aggregate monthly premiums that would be payable under
            such policies through their termination dates in the absence of an
            increase.

      (d)   In the event of termination of the Agreement, the Employer shall pay
            an Additional Quarterly Premium attributable to the Arrangement
            Quarter in which the Agreement terminates but only for the portion
            of the Arrangement Quarter during which the Agreement was in effect.
            Such Additional Quarterly Premium generally shall be determined and
            due in the manner set forth in section 3(b) of the Agreement;
            provided however, that the Additional Quarterly Premium attributable
            to any partial Arrangement Month shall be calculated based on the
            proration formula set forth in section 4(e) below.

      (e)   If the Agreement is terminated other than at the end of an
            Arrangement Month, unless the Quoted Premium is itself prorated
            under the terms of the Policy, the Maximum Monthly Employer Benefit
            Obligation and the MP Premium for the month in which termination
            occurs shall be prorated based upon the ratio of the number of
            calendar days in the Arrangement Month before termination to the
            total number of calendar days in the Arrangement Month.

      (f)   If the Agreement is terminated retroactively and any Policy remains
            in effect after such retroactive termination date, amounts due and
            paid by the parties under the Agreement after the effective date of
            termination shall be credited against their respective obligations
            under the Policy after such date.

      (g)   If the Agreement is terminated, the MP Premium and the Maximum
            Monthly Employer Benefit Obligation for the last Arrangement Month
            prior to the termination date shall be adjusted as authorized in
            Exhibit E of the MP Administrative

                                       13

            Services Agreement to include the effect of any additions,
            terminations or changes in coverage not reflected at the time of
            termination in respect of Arrangement Months prior to termination.

      (h)   In the event that either party reasonably believes that any state or
            other jurisdiction may impose a penalty on it for proceeding with
            its performance under the Agreement, such party will promptly advise
            the other party of such belief and the basis therefor. In such event
            the parties agree to cooperate in good faith to resolve such matter
            to the satisfaction of both parties. After a good faith effort by
            the parties to eliminate the risk of a material penalty being
            imposed, if the matter is not resolved to the satisfaction of both
            parties, the party upon which such penalty may be imposed may
            immediately discontinue the Agreement's application in such state or
            jurisdiction by providing notice to that effect to the other party.
            In that event, the Agreement will continue to apply in all other
            states or jurisdictions.

5.    CHANGES IN MAXIMUM MONTHLY EMPLOYER BENEFIT OBLIGATION AND PREMIUM.

      (a)   The Company may change the percentage of the *** used to calculate

            If the total number of Employees covered by all of the Policies and
            Non-MP Policies changes by *** or more compared to the total number
            of Employees covered by all of the Policies and Non-MP Policies on
            the later of (x) the Effective Date of the Agreement or (y) ***,
            then that Rate may be changed by the Company.

      (c)   The change in Rate described in subsection (b) shall be effective

   EXHIBIT A - REVIEWS AND ESTABLISHMENT OF MONTHLY PAYABLE RATES AND PREMIUMS

1.    The Policies. The Employer has entered into a Minimum Premium Arrangement
      covering each of the Company's insurance policies or HMOs that is
      permitted to have such an arrangement. The Arrangement covers those
      Policies identified in section 1(s) of the Agreement. The Company has also
      issued Non-MP Policies to the Employer which policies are not subject to
      the Minimum Premium Arrangement.

2.    Procedure for Establishing Premiums

      a.    A monthly *** rate for the Policies and the Non-MP Policies
            collectively ("Monthly Payable Rate") is established for each
            Arrangement Quarter as provided in this Exhibit A. Each Arrangement
            Quarter, the Company sets the monthly premium for Employees covered
            under each Policy and Non-MP Policy based on the *** of Employees
            among the Policies and the Non- MP Policies in order to produce a
            *** rate that *** the Monthly Payable Rate for the Arrangement
            Quarter. (The monthly premium for each Policy corresponds to the
            "Quoted Premium" referenced in the Agreement.)

      b.    The Monthly Payable Rate per covered Employee for the first and
            second quarters of 2002 shall be fixed at the rates provided below.

<Table>
<Caption>
                  Period            Med.             Dental
                  ------            ----             ------
                  <S>               <C>              <C>
                  1Q 2002           $***             $***
                  2Q 2002           $***             $***
</Table>

            Beginning with the third quarter of 2002, the Monthly Payable Rate
            shall be established as provided in section 4 of this Exhibit.

3.    Reviews of Experience under Policies and Non-MP Policies

      a.    Within 90 calendar days following the end of each Arrangement Year,
            the Company shall review the

                                       21
<PAGE>

            Employer's aggregate experience under the Policies and the Non-MP
            Policies for that Arrangement Year ("Annual Review"). As part of the
            Annual Review, the Company shall determine whether an aggregate
            Deficit or Surplus exists with respect to the Policies and the
            Non-MP Policies based on an analysis of the Incurred Claims,
            Expenses and Policy Revenue for the Arrangement Year, which analysis
            shall be provided in a written report to the Employer within 90
            calendar days of the close of such Arrangement Year. That report
            shall be in a form substantially similar to and contain the
            information described in Appendix 1 attached to this Exhibit A.

      b.    Within 45 calendar days following the end of each Arrangement
            Quarter, the Company shall provide to the Employer a report

            month and paid health benefits under the Non-MP Policies by incurral
            month, Expenses and Policy Revenue for the Arrangement Quarter
            ("Quarterly Review").

      c.    As part of the Quarterly Review, the Company shall provide to the
            Employer a written list of Policies and Non-MP Policies that were
            effective at any time during the Arrangement Quarter under review
            ("Current Policy List").

4.    Prospective Adjustment of Monthly Payable Rate and Premiums

      a.    Beginning with the third Arrangement Quarter of 2002, the Company
            shall, ***, establish in advance the Monthly Payable Rate for each
            Arrangement Quarter. In establishing the Monthly Payable Rate for an
            Arrangement Quarter, the Company shall take into account any
            Accumulated Deficit or Accumulated Surplus, but shall not be
            required to *** of any Accumulated Deficit or Accumulated Surplus in
            the Monthly Payable Rate of a single Arrangement Quarter. The
            Company shall notify the Employer of the Monthly Payable Rate for
            the third Arrangement Quarter of 2002 by May 31, 2002, for the
            fourth Arrangement Quarter of 2002 by August 31, 2002, and for the
            first Arrangement Quarter of 2003 by October 31, 2002. For all
            subsequent Arrangement Quarters, the Company shall notify the
            Employer of the applicable Monthly Payable Rate at least 90 calendar
            days in advance of the start of the Arrangement Quarter.

                                       22
<PAGE>

      b.    The Company is authorized, ***, to revise the premium of any Policy
            or Non-MP Policy for each Arrangement Quarter so as to result in a
            *** rate for all Policies and Non-MP Policies that *** the revised
            Monthly Payable Rate for that Arrangement Quarter.

5.    Termination Review

      a.    Upon termination of the Agreement, the Company shall provide a
            two-step termination review, substantially in the form of the Annual
            Review ("Termination Review"). The two steps in the Termination
            Review shall be:

            i.    Within 10 calendar days after the termination of the
                  Agreement, the Company shall determine the Accumulated Deficit
                  or Accumulated Surplus as of the date of the termination of
                  the Agreement ("Initial Termination Review").

            ii.   Within 195 calendar days after the termination of the
                  Agreement and all Policies and Non-MP Policies (except those
                  issued to a Client as well as, or instead of, to the
                  Employer), the Company shall determine the Accumulated Deficit
                  or Accumulated Surplus as of the end of the last Arrangement
                  Quarter (or Partial Arrangement Quarter) ("Final Termination
                  Review").

      b.    In calculating the Accumulated Deficit or Accumulated Surplus for
            purposes of the Termination Review, "Non-MP Policies" shall include
            those policies or group contracts issued by the Company that were
            but are no longer covered by the Minimum Premium Arrangement.

      c.    If the Final Termination Review demonstrates an Accumulated Surplus,
            the Company shall pay to the Employer an amount equal to the
            Accumulated Surplus within 10 calendar days after the completion of
            the Final Termination Review.

                                       23
<PAGE>

      d.    If the Initial Termination Review and/or Final Termination Review
            demonstrates an Accumulated Deficit, the Company shall have such
            rights to the balance in the Security Deposit as described in the
            Security Deposit Agreement.

RE:  Benefits Account Establishment

Dear Kevin Kerlejza:

UnitedHealthcare and Administaff of Texas, Inc. have entered into an Insured
Minimum Premium Arrangement whereby various affiliates of UnitedHealthcare will
administer benefits pursuant to the provisions of Administaff of Texas Inc.
benefits plan. In connection with that arrangement, UnitedHealthcare's standard
procedure is to have the customer establish a bank account from which
UnitedHealthcare affiliates draw to pay claims. We have requested that, as to
the Administaff of Texas, Inc.'s Benefit plan, UnitedHealthcare affiliates
instead make claims payments from a UnitedHealthcare account at J.P. Morgan
Chase Bank (Bank) into which Administaff of Texas, Inc. will deposit funds. This
is to advise you that UnitedHealthcare and its affiliates are indemnified and
held harmless by Administaff of Texas, Inc. for any and all federal, state,
local or other governmental demand, charge or tax (by whatever named called)
assessed against or imposed upon them arising out of UnitedHealthcare's
establishing a bank account as requested by Administaff of Texas, Inc. and or
making such payments as aforesaid. This account will be known as:
UnitedHealthcare Administered Plan for Administaff of Texas, Inc. -
Medical/Dental Benefits Account.

The benefits account will be used to pay benefits covered under the Administaff
of Texas, Inc.'s health plan. Drafts in payment of these benefits will be drawn
by UnitedHealthcare. The benefits account will maintain a standing balance
determined by UnitedHealthcare to cover the one day assignment lag due to next
day presentments.

We will be funding the benefits account at J. P. Morgan Chase Daily via a Wire
Transfer initiated by UnitedHealthcare.

                                       1

SECTION 2: PERFORMANCE UNDER THE POLICIES

(a)      The Company shall perform each of its duties and obligations under each
         Policy in accordance with such Policy's terms and all applicable laws
         and regulations. To the extent that, pursuant to a Policy, the Company
         is responsible for the performance of any duty imposed on the Employer
         and/or the Plan under applicable laws and regulations, including but
         not limited to ERISA and the Health Insurance Portability and
         Accountability Act, the Company shall perform such duty in accordance
         with such laws and regulations.

(b)      The Employer hereby and under the Policies designates the Company,
         pursuant to a procedure set forth in the Plan, as the "fiduciary" as
         defined by ERISA for the purpose of (i) reviewing, making decisions on
         and paying claims for Health Benefits and (ii) reviewing and making
         decisions on denials of such Health Benefits. The Company shall serve
         as the final review committee under the Plan to determine for all
         parties all questions relating to the payment of Health Benefits and
         shall have the discretion, authority, and responsibility to construe
         and interpret the terms of the Plan and to make factual determinations.

(c)      The rate of accuracy of Health Benefit payments by the Company under
         each Policy and each Non-MP Policy shall be consistent with the
         accuracy rate that a reasonably prudent claims administrator would be
         expected to achieve under similar circumstances. The amounts payable by
         the Employer under the Agreement, the MP Financial Agreement and the
         Policies and Non-MP Policies shall be subject to the modifications
         specified in the performance standards set out in Exhibit A.

(d)      The Company shall provide services to recover Overpayments, as defined
         below, paid under the Policies and Plan benefits that were paid under
         the Policies and are recoverable by the Plan because payment was or
         should have been made by a third party (other than in connection with
         coordination of benefits, Medicare, or other Overpayments) for the same
         expense.

         (i)      The Company engages affiliated and unaffiliated vendors to
                  assist in the recovery of Overpayments and third party claims
                  made with respect to the Policies and Non-MP Policies. The
                  fees charged by both affiliated and

                                       6
<PAGE>

                  unaffiliated vendors are netted against any recoveries. If the
                  fee charged by any affiliated vendor exceeds ***% of the
                  recovery, the Company shall notify the Employer within 30
                  calendar days of the effective date of such charge. The
                  Employer shall not be responsible for the cost of recovering
                  any Overpayments made by the Company due to the Company's
                  gross negligence as determined by mutual agreement of the
                  parties or by a court or other tribunal.

         (ii)     The Employer delegates to the Company the discretion and
                  authority to develop and use standards and procedures for any
                  recovery under this section, including but not limited to,
                  whether or not to seek recovery, what steps to take if the
                  Company decides to seek recovery, and under what circumstances
                  to compromise a claim or settle for less than the full amount
                  of the claim. The Employer recognizes that use of these
                  standards and procedures may not result in recovery or in full
                  recovery for any particular case. The Company will not pursue
                  any recovery if any applicable law does not permit it, or, if
                  recovery would be impractical. The Company may choose to
                  initiate litigation to recover payments, but it shall have no
                  obligation to pursue litigation. If the Company initiates
                  litigation, the Employer shall cooperate with the Company in
                  the litigation.

         (iii)    If the Agreement terminates, or, if the Company's recovery
                  services terminate, the Company may, but is not required to,
                  continue to recover any Overpayments. The Company shall
                  include Overpayments recoveries in the Termination Review (as
                  defined in Exhibit A to the MP Financial Agreement) in the
                  manner reflected in Exhibit A to the MP Financial Agreement,
                  and the Company shall otherwise be authorized to retain all
                  Overpayments recoveries obtained after the Claims Recognition
                  Date (as defined in the MP Financial Agreement).

         (iv)     The Employer will not engage any entity except the Company to
                  provide these recovery services without the Company's prior
                  approval.

         (v)      For purposes of the Agreement, "Overpayments" shall mean
                  payments that exceed the amount payable under a policy (for
                  example, because of a provider billing error,

                                       7
<PAGE>

                  retroactive or inaccurate eligibility information,
                  coordination of benefits, Medicare disputes, or missing
                  information), and other overcharges made by providers,
                  including hospitals, discovered during the course of a
                  hospital bill audit.

(e)      Claims Incurred prior to termination of any Policy shall be processed
         in accordance with such Policy.

SECTION 3: ADDITIONAL SERVICES

The Company shall provide to the Employer those additional services identified
in Exhibit B. Fees for those services are specified in the Exhibit.

SECTION 4: MAINTENANCE OF RECORDS AND REPORTING TO THE EMPLOYER

(a)      The Company will maintain all claims records for the period required by
         ERISA. Following termination of the Agreement, the Company will supply
         the Employer with historical information in the Company's possession
         reasonably needed by the Employer to administer the Plan. In addition,
         during the year following termination, the Employer may request and the
         Company shall provide, at its prevailing charge, the following
         information:

         (i)      As to each Policy and Non-MP Policy that terminates at any
                  date other than December 31, the following reports for the
                  relevant period of the calendar year in which such Policy or
                  Non-MP Policy terminates:

                  (A)      Year-to-date claims analysis for such year
                           reflecting, for each Participant, total charges,

SECTION 5: INFORMATION ACCESS, AUDIT AND CONFIDENTIALITY

(a)      Employer's Access to Information. During the term of the Agreement, if
         in order to administer the Plan, the Employer reasonably requests
         information, for an auditor or otherwise, that the Company has in its
         possession, the Company will provide access to that information, if
         legally permissible, as long as the information relates to the
         Company's services under the Agreement, and the Employer provides (60)
         sixty calendar days prior notice of the need for the information.

         (i)      The Employer hereby represents that any request by the
                  Employer for disclosure of any information that contains
                  personally identifiable information about a Participant
                  ("Confidential Participant Information") shall constitute the
                  Employer's representation to the Company that the Participant
                  has authorized disclosure to the Employer or the Employer
                  otherwise has the legal authority to have access to the
                  information. The Employer must also represent at the time of

         (ii)     The Company will provide information only while the Agreement
                  is in effect, unless the Employer demonstrates that the
                  information is required for Plan purposes and such disclosure
                  is permitted by law. The Employer shall pay the Company's
                  reasonable expenses in providing information after the
                  termination of the Agreement.

         (iii)    The Company will also provide reasonable access to information
                  to an entity providing services to the Employer, such as an
                  auditor or other consultant, upon request. Before the Company
                  gives access to Confidential Participant Information to that
                  entity, that entity will be required to sign a Third Party
                  Disclosure Agreement, substantially in the form of Exhibit D.

                  reasonable and agreed to by the Company, which consent shall
                  not be unreasonably withheld. All audits shall be limited to
                  information relating to the calendar year in which the audit

                  technique as reasonably approved by the Company (for purposes
                  of this subsection (b), "Scope").

         (ii)     The Employer will pay any expenses that the Employer incurs,

                  the Company, for more than one audit every twelve (12) months,

                  additional resources, facility fees, and other incremental

                  coverage for such ***.

         (iii)    If the Company exercises its right under section 6(f)(i) of
                  the Minimum Premium Services Agreement to decline the addition
                  to the MP Arrangement and to the Non-MP Policies of such New
                  PEO Clients, or imposes conditions on such a proposed addition
                  that are unacceptable to the Employer in its sole discretion,
                  the exclusivity provisions of section 6(b)(iv) above shall not
                  apply and the Employer may contract with any other *** New PEO
                  Clients on such terms as it shall determine.

                                       16

         (iv)     A Client once covered under the MP Arrangement may not be
                  deemed a New PEO Client or covered under any arrangement
                  exclusively for New PEO Clients.

SECTION 7: DISPUTES AND INDEMNIFICATION

(a)      The Employer agrees to indemnify and hold harmless the Company from any
         and all liability, loss, damages, fines, penalties and costs, including
         but not limited to, expenses and reasonable attorneys' fees, which the
         Company shall sustain arising out of or in connection with (1) any
         gross negligence or material breach of the Agreement on the part of the
         Employer, (2) any determination by the Employer regarding the
         eligibility for coverage under a Policy or a Non-MP Policy of an
         Employee or Employee's dependent, (3) any direction of the Employer to
         the Company, (4) the offering or termination of the Policies or Non-MP
         Policies, or the manner of the offering or termination of the Policies
         or Non-MP Policies, to Clients, or (5) the release or use by Employer
         of any information obtained from the Company pursuant to section 5(a),
         unless the parties agree or it is determined in a final non-appealable
         decision by a court or regulatory agency having jurisdiction of the
         matter that the liability therefore was the direct consequence of
         criminal conduct or fraud on the part of the Company or negligence or a
         material breach of the Agreement on the part of the Company.

(b)      The Company agrees to indemnify and hold harmless the Employer and/or
         the Plan from any and all liability, loss, damages, fines, penalties
         and costs, including but not limited to, expenses and reasonable
         attorneys' fees, that the Employer or Plan shall sustain arising out of
         or in connection with gross negligence or material breach of the
         Agreement on the part of the Company or any direction of the Company to
         the Employer, unless the parties agree or it is determined in a final
         non-appealable decision by a court or regulatory agency having
         jurisdiction of the matter that the liability therefore was the direct
         consequence of criminal conduct or fraud on the part of the Employer or
         negligence or a material breach of the Agreement by the Employer. The
         Company shall not indemnify or hold harmless the Employer or the Plan
         for any losses arising out of Overpayments. If Health Benefits are
         required to be paid pursuant to any judgment in favor of the plaintiff
         or a settlement with the plaintiff or the order of a regulatory agency
         having

                                       17
<PAGE>

         jurisdiction of the matter and such judgment or settlement is final or
         payable during the term of the Agreement, any portion of such judgment
         or settlement attributable to Health Benefits shall be treated as a
         claim for Health Benefits at the time that the judgment or settlement
         is final and shall be paid by the Company to the same extent as any
         other claim for Health Benefits under the provisions of section 5 of
         the Agreement and section 2 of the MP Financial Agreement.

(c)      The Company and the Employer shall promptly advise each other as to
         matters which come to their respective attentions involving potential
         legal actions or regulatory enforcement activity which involve the Plan
         or are related to the activities of either party with respect to the
         Plan or the Agreement and shall promptly advise each other of legal
         actions or administrative proceedings which have actually commenced.

(d)      In the event that a lawsuit or administrative proceeding is brought
         against the Employer or the Plan but not the Company, the defense and
         associated costs of such action or proceeding shall be paid by the
         Employer, provided that the costs, including attorneys' fees, of such
         defense shall be reimbursed to the Employer or Plan by the Company to
         the extent the Employer or the Plan is entitled to indemnification by
         the Company under subsection (b) of this section 7. The Company shall
         cooperate fully with the Employer in the defense of any such action or
         proceeding arising out of matters related to the Agreement. The
         Employer agrees not to oppose any attempt made by the Company to
         intervene in such action or proceeding, provided there is no conflict
         of interest between the Company and the Employer or the Plan.

(e)      In the event that a lawsuit or administrative proceeding is brought
         against the Company arising out of the performance of its duties under
         the Agreement, the defense of and associated costs of such action or
         proceeding shall be paid by the Company, provided that the costs,
         including reasonable attorneys' fees, of such defense shall be
         reimbursed to the Company by the Employer to the extent the Company is
         entitled to indemnification by the Employer under subsection (a) of
         this section. The Employer shall cooperate fully with the Company in
         the defense of any such action or proceeding arising out of matters
         related to the Agreement. The Company agrees not to

                                       18
<PAGE>

         oppose any attempt made by the Employer to intervene in such action or
         proceeding, provided there is no conflict of interest between the
         Company and the Employer or the Plan. If the Employer or the Plan is
         also named as a party in such action or proceeding, the Employer may
         request that the counsel engaged by the Company also provide for the
         defense of the Employer and/or the Plan. If there is no conflict of
         interest between the Company and the Employer or the Plan, the Company
         shall take all reasonable measures to comply with the Employer's
         request. If such counsel does not provide for the Employer's or Plan's
         defense, then the Employer and Plan shall pay for the defense and
         associated costs as provided in subsection (d) of this section, subject
         to the Employer's and/or the Plan's right to reimbursement under such
         subsection.

SECTION 8: TAXES AND ASSESSMENTS

(a)      In the event that a state or other jurisdiction, in accordance with
         existing or future law, determines that the Company is liable for
         payment of any tax, surcharge or assessment (other than taxes based
         upon net income) (individually or collectively, "Tax") with respect to
         any aspect of the Plan, the Policies, the Non-MP Policies, the MP
         Arrangement, or the Agreement, the Employer agrees to reimburse the
         Company for the amount of any such Tax, any interest expense assessed
         against or incurred by the Company before or after payment of such Tax,
         and any other charges, penalties or fines in connection therewith,
         including reasonable attorneys' fees, that the Company may sustain in
         connection with the payment of such Tax, provided, however, that the
         Company shall have given the Employer prompt notification of the
         imposition of any such Tax.

         (i)      Subject to the provisions of section 8(a)(ii), any such amount
                  shall be due and payable upon written notification by the
                  Company to the Employer, regardless of whether such
                  notification occurs during the term or following the
                  termination of the Agreement. The Employer shall indemnify and
                  hold harmless the Company from any liability, loss, damages,
                  fines, penalties and costs, including reasonable attorneys
                  fees, which the Company may sustain arising out of or in
                  connection with any compromise, litigation or appeal by the
                  Employer of any

                                       19
<PAGE>

                  Tax or any delay in payment of such Tax as a result of such
                  compromise, litigation or appeal.

         (ii)     With respect to any Tax imposed on the Company solely as a
                  result of the Employer's status as policyholder or sponsor of
                  the Plan, upon Employer's compliance with any bond, security
                  or other legal requirement imposed on a party contesting such
                  a Tax, the Employer shall have the sole discretion in
                  determining whether any such Tax shall be paid, compromised,
                  litigated or appealed and as to all matters of procedure,
                  compromise, defense or appeal of any other aspects concerning
                  liability for any such Tax, except to the extent that the
                  Company would thereby be in violation of any applicable law or
                  rule or would suffer any injury, loss or liability that would
                  not be fully compensable under section 8(a).

         (iii)    The Employer shall not be obligated to reimburse the Company
                  for that portion of any premium tax assessed against the
                  Company that was taken into account by the Company in
                  establishing the Quoted Premium (as defined in the MP
                  Financial Agreement) under a Policy or the premium under a
                  Non-MP Policy.

(b)      In the event that a state or other jurisdiction, in accordance with
         existing or future law, imposes upon the Company the duty to act as
         agent for collection of any Tax imposed on the Plan or the Employer or
         with respect to any aspect of the Plan, a Policy, the MP Financial
         Agreement, or the Agreement, the Employer will pay over any such amount
         to the Company when requested to do so by the Company, subject to
         receipt by the Employer from the Company of prompt notice concerning
         such matter and exercise by the Employer of its rights as stated under
         subsection 8(a) above.

SECTION 9: EFFECTIVE DATE AND AGREEMENT PERIOD

The Agreement shall be effective as of January 1, 2002 ("Effective Date") for a

SECTION 11: TERMINATION OF AGREEMENT

(a)      The Agreement shall terminate on the date that the MP Financial

(b)      In the event that either party reasonably believes that any state or
         other jurisdiction may impose a penalty on it for proceeding with its
         performance under the Agreement, such party will promptly advise the
         other party of such belief and the basis therefore. In such event the
         parties agree to cooperate in good faith to resolve such matter to the
         satisfaction of both parties. After a good faith effort by the parties
         to eliminate the risk of a material penalty being imposed, if the
         matter is not resolved to the satisfaction of both parties, the party
         upon which such penalty may be imposed may immediately discontinue the
         Agreement's application in such state or jurisdiction by providing
         notice to that effect to the other party. In that event, the Agreement
         will continue to apply in all other states or jurisdictions.

(c)      Termination of the Agreement shall not extinguish the rights or
         liabilities of either party arising prior to termination.

including reasonable attorneys' fees, of any amounts due the other party under

the Company, by any of its affiliates or by any subcontractor selected by it,
provided that the Company shall not be relieved of any of its obligations
hereunder. Except as set forth in the preceding sentence, neither party may
assign or delegate any of the

                                       21
<PAGE>

rights and obligations hereunder to any third party without the prior written
consent of the other party.

The Agreement shall be governed by applicable federal law and, to the extent not
governed by federal law, the laws of the State of Texas.

SECTION 15: ENTIRE AGREEMENT, AMENDMENT AND WAIVER

(a)      Upon execution of the Agreement, all prior or contemporaneous letters
         of understanding, agreements, requests for proposal, proposals,
         representations, statements, negotiations and understandings, whether
         oral or written, are hereby terminated and superseded by the Agreement,

         modifications on behalf of the party. Each party shall be entitled to
         rely on the other's certification of authority unless and until it is
         modified.

         breach excused, unless the party claimed to have waived the term or

         Agreement, the MP Financial Agreement, the Security Deposit Agreement
         or the Policies or Non-MP Policies, the following order of precedence
         shall be followed in resolving the conflict. The terms of the Security
         Deposit shall first control, then the MP Financial Agreement, then the
         Agreement and lastly the Policies or the Non-MP Policies, as
         applicable.

(e)      The parties' respective rights and obligations under sections 2(a)-(d),
         4(a)-(d), 5(a), 5(d), 7, 8 and 12 of the Agreement shall survive

                        EXHIBIT A - PERFORMANCE STANDARDS

1.       GENERAL DESCRIPTION

         a. Performance Standards and Guarantee Period

         Pursuant to section 2(c) of the Agreement, this Exhibit describes the
performance standards applicable to services provided under the Agreement with
respect to medical Policies and Non-MP Policies ("Performance Standard" or
"Performance Standards"). These standards apply to the annual period that begins
on January 1 and ends on December 31 of the same calendar year ("Guarantee
Period").

         The reports and metrics referenced in this Exhibit are those reports
and metrics utilized by the Company on the Effective Date. From time to time,
the Company may change the reports and metrics that it uses. If so,
substantially similar metrics and reports will be substituted for those set
forth in this Exhibit A. In addition, if a report or metric is changed, the
Company will modify any affected Performance Standard to the extent necessary to
carry out the intent of the parties, provided that the modified Performance
Standard shall be at least as favorable to the Employer as the standard offered
by the Company to other key account customers at the time of the modification.

         b. Premium Credits

         To the extent provided below, the Employer shall be entitled to a
Premium Credit if the Company fails to meet *** or more of the Performance
Standards during a Guarantee Period. The Premium Credit due for a Guarantee
Period shall be applied to premiums due to the Company for the first Arrangement
Month following the Quarterly Review for the fourth Arrangement Quarter of each
year.

         c. Reporting

         The Company shall report to the Employer the Performance Standards
results as part of each Quarterly Review. Performance Standard results will be
summarized and reported for the Guarantee Period as part of the Annual Review.
The amount of Premium Credit due as a result of the Company's failure to meet
any of the Performance Standards will be determined as part of the Quarterly
Review.

                                       26
<PAGE>

         d. Special Provision for 2002

         For 2002, the Guarantee Period will be modified to begin on July 1,
2002 and end on December 31, 2002. For 2002, the sum of the Premium Credits for
all categories described below shall not exceed $*** with the dollar amount
described in each category below reduced by *** percent. In years after 2002,
Premium Credits in the aggregate may not exceed $***. The potential Premium
Credits by category are listed in sections 2 through 5 below.

         e. Non-Performance by the Company May be Excused

         The Company shall not be required to provide a Premium Credit where the
Company's failure to meet any Performance Standard is due to fire, embargo,
strike, war, accident, act of god, voluntary or involuntary compliance with any
valid or invalid law or regulation of any governmental agency or authority or
***.

2.       ELIGIBILITY LOADING

         The Company will load eligibility transmissions to the UnitedHealth
Group Eligibility System within *** business days of receipt. A tape load will
be considered to have met this standard if the elapsed time between the date the
tape is received by the Company and the date upon which the tape is loaded to
the eligibility system(s) is *** business days or less. The guarantee applies to
tapes submitted consistent with the format outlined in the UnitedHealth Group
Eligibility Handbook (last updated version June 19, 2001) and is not applicable
to tapes that cannot be loaded due to tape errors or for tapes that require
reformatting of data. Tapes must be received prior to 12:00 noon, Eastern Time,
on the date as determined by scheduled tape delivery dates. Otherwise, written
notification of tape delivery must be provided and receipt confirmed by the
Company. If the tape is received after 12:00 noon, Eastern Time, the period for
completion of the loading under this standard commences the following business
day.

         Failure to load ***% of eligibility tapes to the UnitedHealth Group
Eligibility System within *** business days of receipt during the Guarantee
Period will result in a Premium Credit of $***.

         a. Time to Pay

         During a Guarantee Period, the Company will process ***% of all claims
received by the Company within *** business days of receipt, as evidenced by the
Company's date stamp. Timeliness will be measured using the "Time to Pay" report
produced by the Company on a monthly basis. The overall Guarantee Period result
is recalculated using the raw data for such period. The "Time to Pay" results
are always rounded to the nearest whole percent.

         For the Agreement, the criteria will be based upon the results of the
Plano Service Center team servicing the Employer.

         A claim will be considered processed when the claim has been completely
reviewed and a payment determination has been made.

         Time to pay is measured the same way regardless of the timing of the
Company's responses to a claimant.

         Failure to process ***% of all claims received within *** business days
during the Guarantee Period will result in a Premium Credit in the maximum
amount of $***. Credits against this Performance Standard will be applied on a
gradient as follows:

         ***% WITHIN *** BUSINESS DAYS - $ ***

         ***% WITHIN *** BUSINESS DAYS - $ ***

         ***% WITHIN *** BUSINESS DAYS - $ ***

         ***% WITHIN *** BUSINESS DAYS - $ ***

         ***% IN MORE THAN *** BUSINESS DAYS - $ ***

         b. Financial Accuracy

         The Company will maintain a Financial Accuracy rate of not less than
***% for the Guarantee Period. Financial Accuracy is measured by collecting a
statistically significant random sample of claims processed. The sample is
reviewed to determine the percentage of claim dollars processed correctly out of
the total claim dollars submitted for payment. The measurement will be done by
the Company's standard internal quality assurance program based on a periodic
audit of all claims processed by the Plano Service Center team servicing the
Employer. The overall Guarantee Period result is recalculated using the raw data
for such period.

         Failure to maintain a Financial Accuracy rate of at least ***% for the
Guarantee Period will result in a Premium Credit in the maximum

                                       29
<PAGE>

amount of $***. Credits against this Performance Standard will be applied on a
gradient as follows:

         ***% - ***% PAID CORRECTLY - $***

         ***% - ***% PAID CORRECTLY - $***

         ***% - ***% PAID CORRECTLY - $***

         ***% - ***% PAID CORRECTLY - $***

         LESS THAN ***% PAID CORRECTLY - $***

         c. Procedural Accuracy

         The Company will maintain a Procedural Accuracy rate of not less than
***% for the Guarantee Period. Procedural Accuracy is measured by collecting a
statistically significant random sample of claims processed by the Plano Service
Center team servicing the Employer. The sample is reviewed to determine the
percentage of claims processed without non-financial errors.

         The measurement will be done by the Company's standard internal quality
assurance program based on a periodic audit of all claims processed by the Plano
Service Center team servicing the Employer. The overall performance period
result is recalculated using the raw data for such period.

         Failure to maintain a Procedural Accuracy rate of at least ***% for the
Guarantee Period will result in a Premium Credit in the maximum amount of $***.
Credits against this Performance Standard will be applied on a gradient as
follows:

         ***% - ***% PAID CORRECTLY - $***

         ***% - ***% PAID CORRECTLY - $***

         ***% - ***% PAID CORRECTLY - $***

         ***% - ***% PAID CORRECTLY - $***

         LESS THAN ***% PAID CORRECTLY - $***

         d. Items Excluded From Claim Operations Performance Measurements

         With some products (e.g., HMO), financial reimbursement arrangements
are contractually negotiated with providers (physicians, labs, etc.), that
budget the payment they receive for certain services. Periodic payments are made
to the providers in return for their agreement to provide the negotiated
services to network members. Services provided under these arrangements are not
processed as a

                                       30
<PAGE>

typical "claim" and, as a result, results from the networks featuring these
arrangements are not included in the performance statistics outlined above.

         The claims that are included in Claim Operations performance categories
are limited to medical claims processed through the UNET claims system(s).
Claims processed through any other system, including claims for other products
such as *** coverage, are not included in the calculation of the performance
measurements stated above.

5.       MEMBER PHONE SERVICE PERFORMANCE STANDARDS

         a. Average Speed to Answer

         This standard applies to the claim team and/or the member service team
that provide service for the Employer's Employees. The Company will guarantee
that calls will sequence through the Company's automated telephone call
distribution system and be answered by a customer service representative in ***
seconds or less, on average. The Average Speed to Answer will be measured by the
standard tracking reports produced by the Company's automated phone system for
all the calls handled by the Plano Service Center team servicing the Employer.

         If the Average Speed to Answer for the Guarantee Period is greater than
*** seconds, a Premium Credit will be due. The maximum amount of the Premium
Credit will be $***. Credits against this performance measure will be applied on
a gradient as follows:

         *** SECONDS OR LESS - $***

         *** SECONDS OR LESS - $***

         *** SECONDS OR LESS - $***

         *** SECONDS OR LESS - $***

         MORE THAN *** SECONDS TO ANSWER - $***

         b. Abandonment Rate

         This standard applies to the claim team(s) and/or the member services
team(s) which provide service for the Employer's Employees. The Company will
guarantee that calls will sequence through the Company's automated telephone
call distribution system such that the average abandonment rate will be no
greater than *** percent. The Abandonment Rate results will be measured by the
standard tracking reports produced by the Company's automated phone system for
all calls handled by the Plano Service Center team servicing the Employer.

                                       31
<PAGE>

         If the Abandonment Rate for the Guarantee Period is greater than ***%
on average, for all locations providing member phone service to the Employer's
Employees, a Premium Credit will be made due. The maximum amount of the credit
will be $***. Credits against this performance measure will be applied on a
gradient as follows:

      ***% - ***% OF CALLS ABANDONED - $***

      ***% - ***% OF CALLS ABANDONED - $***

      ***% - ***% OF CALLS ABANDONED - $***

      ***%  - ***% OF CALLS ABANDONED - $***

      MORE THAN ***% OF CALLS ABANDONED - $***

6.       OVERALL MEMBER SATISFACTION PERFORMANCE STANDARD

         This standard applies to the member service teams that provide HMO,
EPO, PPO and Managed Indemnity services for the Employer's Employees. The
Company will conduct, on *** basis, a Uniprise Customer Satisfaction Survey. The
Overall Satisfaction question used reads:

         "Overall, how satisfied are you with the way the Company administers
         your medical health insurance plan, such as processing your claim or
         helping answer any questions or resolving any problems you may have?"

         If less than ***% of the respondents for the Plano Service Center team
providing services for the Employer's Employees are satisfied overall (i.e., if
***% of respondents do not respond with either completely satisfied, very
satisfied or somewhat satisfied), a Premium Credit of $*** will be due.

                  EXHIBIT D - THIRD PARTY DISCLOSURE AGREEMENT

         This THIRD PARTY DISCLOSURE AGREEMENT ("Agreement") is entered into by
and between Administaff of Texas, Inc. ("Employer"), [Examiner Name]
("Examiner") and United HealthCare Insurance Company for itself and its
affiliated companies ("United HealthCare"). These parties acknowledge and agree
as follows:

         Employer and United HealthCare entered into the Minimum Premium
Administrative Services Agreement ("the Agreement") under which United
HealthCare provides claims administration and other services for Employer's
employee welfare benefit plan ("Plan"). Employer has retained Examiner to
perform an examination, audit or other evaluation of the files, books, and/or
records of United HealthCare pertaining to the Plan ("Examination").

         Employer has requested that solely for purposes of the Examination,
United HealthCare disclose to Examiner certain documents, statistical
information and other information which is commercially valuable, confidential,
proprietary, or trade secret ("Proprietary Information") and also materials
which may contain medical or other individually identifiable information
("Confidential Medical Information"). Proprietary Information and Confidential
Medical Information shall collectively be referred to in the Agreement as
"Confidential Information". United HealthCare has agreed to disclose this
Confidential Information subject to the terms of the Agreement.

         The Examination shall take place on the date or date(s) mutually agreed
upon by the parties.

         Confidential Information disclosed by United HealthCare, its agents,
subsidiaries and affiliates, to Examiner in connection with the Examination,
including all copies thereof, shall be used by Examiner only as permitted by the
Agreement. Confidential Information shall not include information: (i) generally
available to the public or generally known in the insurance industry or employee
benefit consulting community prior to or during the time of the Examination
through authorized disclosure; (ii) obtained from a third party who is under no
obligation to United HealthCare not to disclose such information; or (iii)
required to be disclosed by subpoena, or other legal process.

         USE: Examiner shall: (a) not use (deemed to include, but not be limited
to, using, exploiting, duplicating, recreating, modifying,

                                       36
<PAGE>

decompiling, disassembling, reverse engineering, translating, creating
derivative works or disclosing Confidential Information to another person or
permitting any other person to do so) Confidential Information except for
purposes of the Examination; (b) limit use of Confidential Information only to
its authorized employees (deemed to include employees as well as individuals who
are agents or independent contractors of Examiner) who have a need to know for
purposes of the Examination; and (c) may release Confidential Information in
response to a subpoena or other legal process to disclose Confidential
Information, after giving United HealthCare reasonable prior notice of such
disclosure.

         At the conclusion of the Examination, Examiner shall either relinquish
to United HealthCare, or destroy (with such destruction to be certified to
United HealthCare), all Confidential Information. If during the course of the
Examination it is discovered that the Agreement has been breached by Examiner
then all Confidential Information shall be relinquished to United HealthCare
upon demand.

         The Agreement binds the parties and their respective successors,
assigns, agents, employers, subsidiaries and affiliates.

         Unauthorized use of Confidential Information by Examiner is a material
breach of the Agreement resulting in irreparable harm to United HealthCare for
which the payment of money damages is inadequate. It is agreed that United
HealthCare, upon adequate proof of unauthorized use, and in addition to any
other remedies at law or in equity that it may have, may immediately obtain
injunctive relief in any court of competent jurisdiction enjoining any
continuing or further breaches and may obtain entry of judgment for injunctive
relief. Examiner consents to said injunctive relief and judgment. Employer and
Examiner agree to indemnify and hold harmless United HealthCare with respect to
any claims and any damages caused by Examiner's breach of the Agreement.

         The requirement to treat all Confidential Medical Information, as
Confidential Information shall survive the termination of the Agreement. The
requirement to treat all Proprietary Information as Confidential Information
under the Agreement shall remain in full force and effect so long as any
Proprietary Information remains commercially valuable, confidential, proprietary
and/or trade secret, but in no event less than a period of three (3) years from
the date of the Examination.

         Neither the Agreement nor Examiner's rights or obligations hereunder
may be assigned without United HealthCare's prior written approval.

                                       37
<PAGE>

         GENERAL: (a) The Agreement is the entire understanding between the
parties as to the subject matter hereof. (b) No modification to the Agreement
shall be binding upon the parties unless evidenced in writing signed by the
party against whom enforcement is sought. (c) Headings in the Agreement shall
not be used to interpret or construe its provisions. (d) The alleged invalidity
of any term shall not affect the validity of any other terms. (d) The Agreement
may be executed in counterparts.

         The parties have caused their authorized representatives to execute the
Agreement.

                EXHIBIT E - ELIGIBILITY REPORTING BY THE EMPLOYER

For purposes of this Exhibit E, "Plan" shall include the plan of benefits
provided by the Employer under the Policies and the Non-MP Policies.

1.       The Employer shall provide to the Company an accounting of the number
         of Clients participating in the Plan as of January 1, 2002.

2.       The Employer understands that the Company requires a seven business day
         period from the date notification is received by the Company of a
         Participant's eligibility or termination of coverage under the Plan in
         order to update the UnitedHealth Group Eligibility System and the
         subsidiary eligibility systems for pharmacy, dental and mental
         health/substance abuse benefits. This seven business day period is
         predicated upon such eligibility information being provided by the
         Employer to the Company in the format consistent with that outlined in
         the UnitedHealth Group Eligibility Handbook (last updated on June 19,
         2001). The Employer agrees to pay the claims of such Participant(s)
         whose coverage has been terminated to the extent they would otherwise
         constitute Health Benefits required to be paid by the Company if the
         Company authorized the payment of the claims during this period, even
         if such persons are no longer eligible for Plan benefits during this
         period.

3.       The Company shall not be required to make retroactive corrections in
         Participant eligibility for benefits Incurred under Policies or Non-MP
         Policies on dates more than 60 calendar days before the date on which
         the corrected information is received by the Company.

4.       In calculating the Quoted Premiums under the Policies and the monthly
         premiums under the Non-MP Policies administered on the Company's UNET
         system (as designated in Exhibit B to the Minimum Premium Financial
         Agreement), the following rule shall apply. A *** shall be due for
         Employees whose effective date of coverage is on or before the 15th of
         that month and no premium shall be due for Employees whose effective
         date of coverage is after the *** of that calendar month. A *** shall
         be due for Employees whose coverage is terminated after the *** of that
         calendar month, and *** shall be due for Employees whose coverage is
         terminated on or before the *** day of that calendar month.

                                       39

5.       Monthly premiums for the Non-MP Policies administered on the Company's
         PRIME system (as designated in Exhibit B to the Minimum Premium
         Financial Agreement) are calculated by the system on an individual
         Non-MP Policy basis using a roster billing process which reflects the
         amount due for individual Participants. The calculation of monthly
         premiums on PRIME uses a *** rule to determine the premium due for
         partial month's coverage as opposed to the *** of the month rule
         described in paragraph 4 above.

                  a.       If at any time an HMO offered by the Employer through
                           the Company ceases to be Competitive, the Employer
                           may in its sole discretion cease offering such HMO
                           and, in any case, the respective market in which such
                           HMO operates shall be deemed a New Market. In any
                           such case, the Employer shall notify the Company of
                           its opinion concerning the Competitive status of such
                           HMO at least *** months before it ceases offering the
                           HMO and shall have the burden of undertaking the
                           steps required to confirm the same in accordance with
                           section B(7)(b) of this Exhibit F. If the Company's
                           HMO becomes Competitive within *** months after its
                           receipt of the Employer's notice, the Employer may
                           not replace it unless and until it is again not
                           Competitive, in which

                                       42

                           case a new notice shall be required and a new ***
                           month corrective period will begin.

                  b.       If at the time the Company begins to offer an HMO
                           option which is Competitive, the Employer is offering
                           an HMO option through a Competing Vendor consistent
                           with the provisions of this Exhibit F, the Employer
                           shall offer each Client in such New Market coverage
                           options for Employees in such New Market not later
                           than the *** of such *** consisting of either (i) the
                           Company's *** and *** options or (ii) such Competing
                           Vendor's *** and, at the Competing Vendor's option,
                           its ***.

         6.       Acquisition by Employer of another Professional Employer
                  Organization: The Employer's use of Competing Vendors to
                  provide coverage to New PEO Clients will not violate the
                  provisions of section 6(b)(iv) of the Agreement or this
                  Exhibit F if such coverage complies with the provisions of
                  section 6(f) of the Agreement.

         7.       Definitions: As used in this Exhibit F, capitalized terms
                  shall have the meanings assigned to them in the Minimum
                  Premium Administrative Services Agreement to which this
                  Exhibit F is attached or, if no meaning is so assigned, the

                  b.       "Competitive" when referring to an HMO option means

                           agreement of the parties has determined, that such
                           product ranks either *** as compared to competing
                           products of other vendors in the designated market.
                           In making any determination of the rank of a product
                           in a market, such consultant shall apply such
                           criteria relating to *** as it shall determine
                           appropriate. All fees and expenses of any such
                           consultant shall be paid by the Employer.
