        the MercFuel Health and Welfare Plans. Except as otherwise specified in

        practicable, each of the foregoing MercFuel Plans as in effect as of the

        Section 2.4 MercFuel's Participation in MAG Plans.

               (a) Participation in MAG Plans. Except as specified otherwise in
        this Agreement or as MAG and MercFuel may mutually agree, MercFuel
        shall, until the Distribution Date, continue to be a Participating
        Company in the MAG Plans to the extent that MercFuel has not established

        to administer, or cause to be administered, in accordance with its terms
        and applicable law, such MAG Plan, and shall have the sole and absolute
        discretion and authority to interpret the MAG Plan, as set forth
        therein. MAG shall not amend any Material Feature of any MAG Plan in
        which MercFuel is a Participating Company, except to the extent: (i)
        such amendment would not materially affect any coverage or benefits of
        MercFuel Employees or MercFuel Transferred Employees under such Plan;
        (ii) MercFuel shall consent to such amendment and such consent shall not
        be unreasonably withheld; or (iii) such amendment is necessary or
        appropriate to comply with applicable law.

               (c) MercFuel's General Obligations as Participating Company.

        individual with whom MAG has entered into an agreement relating to the
        MAG Plans; and (iv) preservation of the confidentiality of participant
        information (including, without limitation, health information in
        relation to FMLA leaves) to the extent not specified otherwise in this
        Agreement.

               (d) Termination of Participating Company Status. Except as
        otherwise may be mutually agreed upon by MAG and MercFuel, effective as
        of the Distribution Date or such other date as MercFuel establishes a
        corresponding Plan (as specified in Section 2.2 or otherwise in this
        Agreement), MercFuel shall automatically cease to be a Participating

               (a) Non-Duplication of Benefits. Except as specified otherwise in
        this Agreement, as of the Distribution Date, or other later date that
        applies to the particular MercFuel Plan established thereafter, the
        MercFuel Plans shall be, with respect to MercFuel Transferred Employees,
        in all respects the successors in interest to, and shall not provide
        benefits that duplicate benefits provided by, the corresponding MAG
        Plans. MAG and MercFuel shall agree on methods and procedures, including
        amending the respective Plan documents, to prevent MercFuel Employees
        from receiving duplicate benefits from the MAG Plans and the MercFuel
        Plans.

               (b) Service Credit. Except as specified otherwise in this
        Agreement, with respect to MercFuel Transferred Employees, each MercFuel
        Plan shall provide that all service, all compensation and all other
        benefit-affecting determinations that, as of the Distribution Date, were
        recognized under the corresponding MAG Plan shall, as of the
        Distribution Date, receive full recognition and credit and be taken into
        account under such MercFuel Plan to the same extent as if such items
        occurred under such MercFuel Plan, except to the extent that duplication
        of benefits would result. Notwithstanding the foregoing, MAG and
        MercFuel shall recognize service with either MAG or MercFuel that was
        recognized as of the Distribution Date, except to the extent provided in
        Subsection 2.5(a) above. The service crediting provisions shall be
        subject to any respectively applicable "service bridging," "break in
        service," "employment date," or "eligibility date" rules under the
        MercFuel Plans and the MAG Plans.

               (c) Assumption of Liabilities. Except as specified otherwise in
        this Agreement (including, without limitation, the exception applicable
        to self-insured Health Plans), the provisions of this Agreement for the
        transfer of Assets relating to MAG Plans to MercFuel and/or the
        appropriate MercFuel Plans are based upon the understanding of the
        parties that MercFuel and/or the appropriate MercFuel Plan will assume
        all Liabilities of the corresponding MAG Plan to or relating to MercFuel
        Transferred Employees, as provided for herein. If any such Liabilities
        are not effectively assumed by MercFuel and/or the appropriate MercFuel
        Plan, then the amount of transferred Assets shall be recomputed
        accordingly, taking into account the retention of such Liabilities by
        such MAG Plan, and Assets shall be transferred from MercFuel and/or the
        appropriate MercFuel Plan to MAG and/or the appropriate MAG Plan so as
        to place MercFuel and/or the appropriate MercFuel Plan in the position
        it would have been in had the initial Asset transfer been made in
        accordance with such recomputed amount of assets.

        Section 2.6 Non-U.S. Employment Matters. MercFuel and MAG each intend
that matters, issues, or Liabilities relating to, arising out of, or resulting
from non-U.S.-related employment matters be handled in a manner that is
consistent with comparable U.S. matters, issues, or Liabilities as reflected in
this Agreement (to the extent permitted by applicable law or as otherwise
specified in the applicable Section or Schedule thereto).

        other date as MAG and MercFuel may mutually agree), MercFuel shall
        establish, or cause to be established, a separate plan or trust, which
        is intended to be tax-qualified under Code Section 401(a), to be exempt

        401(k) Plan.

               (b) 401(k) Plan: Assumption of Liabilities and Transfer of
        Assets. Effective as of the Distribution Date (or such other date as MAG
        and MercFuel may mutually agree): (i) the MercFuel 401(k) Plan shall
        assume and be solely responsible for all Liabilities relating to,
        arising out of, or resulting from MercFuel Transferred Employees under
        the MAG 401(k) Plan; and (ii) MAG shall cause the accounts of the
        MercFuel Transferred Employees under the MAG 401(k) Plan that are held
        by its related trust, whether vested or unvested, to be transferred to
        the MercFuel 401(k) Plan and its related trust, and MercFuel shall cause
        such transferred accounts to be accepted by such Plan and its related
        trust. In MAG's discretion, amounts may be in cash or in kind or a
        combination; except following in kind: (A) MAG stock; (B) MercFuel
        stock; (C) promissory notes reflecting plan loans to MercFuel
        executives. Effective as of the Distribution Date (or such other date as
        MAG and MercFuel may mutually agree), MercFuel shall use its
        commercially reasonable best efforts to enter into agreements
        satisfactory to MercFuel to accomplish such assumption and transfer, the
        maintenance of the necessary participant records, the appointment of
        _______________ as the initial trustees under the MercFuel 401(k) Plan,
        and the engagement of _______________ as the initial recordkeeper under
        the MercFuel 401(k) Plan. MercFuel and MAG each agree to use their
        commercially reasonable best efforts to accomplish this 401(k) Plan and
        related trust spin-off.

               (c) 401(k) Plan: Stock Considerations. As a result of the
        spin-off of the MAG 401(k) Plan and to the extent that immediately prior
        to such time, the MAG 401(k) Plan continues to consist of MAG employer
        securities, then the resulting MAG 401(k) Plan and MercFuel 401(k) Plan
        shall both consist in part of MAG and MercFuel employer securities.
        MercFuel and MAG shall assume sole responsibility for ensuring that
        their respective company stock funds, and underlying employer securities
        held in each such fund, are maintained in compliance with all
        requirements of the SEC.

               (d) No Distribution to MercFuel Transferred Employees. The MAG
        401(k) Plan and the MercFuel 401(k) Plan shall provide that no
        distribution of account balances shall be made to any MercFuel
        Transferred Employee on account of the MercFuel Group ceasing to be an
        Affiliate of the MAG Group as of the Distribution Date.

               (a) MercFuel Health Plans. As of the Distribution Date (or such
        other date(s) as MAG and MercFuel may mutually agree), MercFuel shall
        have established the MercFuel Health Plans listed on Schedule 4.1(a)
        and, correspondingly, MercFuel shall cease to be a Participating Company
        in the MAG Health Plans. MercFuel shall be solely responsible

                                      -11-
<PAGE>   19

        for the administration of the MercFuel Health Plans, including the
        payment of all employer-related costs in establishing and maintaining
        the MercFuel Health Plans, and for the collection and remittance of
        employee premiums, subject to Section 6.2.

               (b) Pending Treatments. Notwithstanding Subsection 4.1(a) above,
        all treatments which have been pre-certified for or are being provided
        to a MercFuel Transferred Employee as of the Distribution Date shall be
        provided without interruption under the appropriate MAG Health Plan (to
        the extent such continued treatment is not provided under a MercFuel
        Health Plan) until such treatment is concluded or discontinued, pursuant
        to applicable Health Plan rules and limitations, but MercFuel shall
        continue to be responsible for all Liabilities relating to, arising out
        of, or resulting from such on-going treatments as of the Distribution
        Date.

               (c) Vendor Arrangements. MAG shall use its commercially
        reasonable best efforts for and on behalf of MercFuel to procure,
        effective as of the Distribution Date (or such other date(s) as MAG and
        MercFuel may mutually agree): (i) Group Insurance Policies, which are
        comparable in the aggregate in all Material Features to the Group
        Insurance Policies entered into by MAG, as set forth in Schedule
        4.1(c)(i) (the "Group Insurance Policies"); and (iii) an HMO Agreement
        which is comparable in the aggregate in all Material Features to the HMO
        Agreement entered into by MAG, as set forth in Schedule 4.1(c)(ii) (the
        "HMO Agreement"). In each case, MercFuel shall, as of the Distribution
        Date (or such other date as MAG and MercFuel may mutually agree),
        establish, adopt and/or implement such contracts, agreements or
        arrangements. MercFuel may, at such future date after the Distribution
        Date, elect to discontinue such contracts, agreements or arrangements in
        accordance with Section 2.3.

               (d) Continuance of Elections, Co-Payments and Maximum Benefits.

                      (i) As of the Distribution Date and for the remainder of
               the plan year in which the Distribution Date occurs (or such
               other period as MAG and MercFuel may mutually agree), MercFuel
               shall make its commercially reasonable best efforts to cause the
               MercFuel Health Plans to recognize and maintain all coverage and
               contribution elections made by MercFuel Employees and MercFuel
               Transferred Employees under the MAG Health Plans and apply such
               elections under the MercFuel Health Plans for the remainder of
               the period or periods for which such elections are by their terms
               applicable. The transfer or other movement of employment between
               MAG to MercFuel at any time upon or before the Distribution Date
               shall neither constitute nor be treated as a "status change" or
               termination of employment under the MAG Health Plans or the
               MercFuel Health Plans.

                      (ii) On and after the Distribution Date, MercFuel shall
               cause the MercFuel Health Plans to recognize and give credit for

               respect to which such expenses have been incurred by MercFuel
               Transferred Employees under the MAG Health Plans for the

               occurs, and (B) all benefits

               for purposes of determining when such persons have reached their
               lifetime maximum benefits under the MercFuel Health Plans.

               (e) HCFA. As of the Distribution Date (or such other date as MAG
        and MercFuel may mutually agree), MercFuel shall assume all Liabilities
        relating to, arising out of, or resulting from claims, if any, under the
        HCFA data match reports that relate to MercFuel Transferred Employees.

        Section 4.2 Health Plans from the Separation Date through the
Distribution Date. Except as otherwise agreed by MAG and MercFuel, for the
period beginning with the Separation Date and ending on the Distribution Date
(or such other period as MAG and MercFuel may mutually agree), MercFuel shall be
a Participating Company in the MAG Health Plans listed on Schedule 4.2(a). MAG
shall administer claims incurred under the MAG Health Plans by MercFuel
Employees before the Distribution Date but only to the extent that MercFuel has
not, before the Distribution Date, established and assumed administrative
responsibility for a corresponding Health Plan. Any determination made or
settlements entered into by MAG with respect to such claims shall be final and
binding. MAG shall retain financial and administrative ("run-out") Liability and
all related obligations and responsibilities for all claims incurred by MercFuel
Transferred Employees before the Distribution Date (or such other date(s) as MAG
and MercFuel may mutually agree), including any claims that were administered by
MAG as of, on, or after the Distribution Date (or such other date(s) as MAG and
MercFuel may mutually agree). Except as set forth in the preceding sentence,
MercFuel shall reimburse MAG for any and all direct and indirect costs and
expenses associated with its participation in the MAG Health Plans, subject to

        shall, until the Distribution Date (or such other date as MAG and
        MercFuel may mutually agree), continue to be a Participating Company in
        the MAG Group Life Plan. MercFuel shall cease to be a Participating
        Company in the MAG Group Life Plan coincident with MercFuel's
        establishment of the MercFuel Group Life Plan (or, if none, MercFuel's
        written notice to MAG of its withdrawal as a Participating Company in
        the MAG Group Life Plan). MercFuel shall reimburse MAG for any and all
        direct and indirect costs and expenses associated with its participation
        in the MAG Group Life Plan, subject to Section 6.2.

               (b) MercFuel's Establishment of MercFuel Group Life Plan. MAG
        shall make its commercially reasonable best efforts to procure an
        arrangement on behalf of MercFuel for a Group Life Plan which shall be
        comparable in the aggregate in all Material Features to the MAG Group
        Life Plan as are financially, administratively and legally practicable.
        If MAG procures such an arrangement, MercFuel will not unreasonably
        withhold its consent to adopt such an arrangement to constitute the
        MercFuel Group Life Plan. MercFuel will reimburse MAG for its direct and
        indirect costs and expenses associated with its procurement,
        preparation, and implementation of the MercFuel Group Life Plan, subject
        to Section 6.2.

to procure, effective as of the Distribution Date (or such other date as MAG and
MercFuel may mutually agree), a MercFuel Long-Term Disability Plan. MercFuel
will reimburse MAG for any and all direct and indirect costs and expenses
associated with its participation in the MAG Long-Term Disability Plan and MAG's
assistance in procuring, preparing, and implementing the MercFuel Long-Term
Disability Plan, subject to Section 6.2.

        Section 4.5 COBRA. MAG shall be responsible through the Distribution
Date (or such other date as MAG and MercFuel may mutually agree), for compliance
with the health care continuation coverage requirements of COBRA and the MAG
Health and Welfare Plans with respect to MercFuel Employees and qualified
beneficiaries (as such term is defined under COBRA). MercFuel shall be
responsible for providing MAG with all necessary employee change notices and
related information for covered dependents, spouses, qualified beneficiaries (as

administratively practicable after the Distribution Date (or such other date as

copy, electronic format, or such other mechanism as is appropriate under the
circumstances), with a list of all qualified beneficiaries (as such term is
defined under COBRA) that relate to the MercFuel Group and the relevant
information pertaining to their coverage elections and remaining COBRA time
periods. Effective as of the Distribution Date (or such other date as MAG and
MercFuel may mutually agree), MercFuel shall be solely responsible for
compliance with the health care continuation coverage requirements of COBRA and
the MercFuel Health and Welfare Plans for MercFuel Transferred Employees and
their qualified beneficiaries (as such term is defined under COBRA); provided,

        Plans which shall be comparable in the aggregate in all Material
        Features to the MAG Leave of Absence Plans as in effect on the

        agree); (ii) MercFuel shall honor all terms and conditions of leaves of
        absence which have been granted to any MercFuel Employee under a MAG
        Leave of Absence Plan or FMLA before the Distribution Date by MAG,
        including such leaves that are to commence after the Distribution Date
        (or such other date as MAG and MercFuel may mutually agree); and (iii)
        MercFuel shall recognize all periods of service of MercFuel Employees
        and MercFuel Transferred Employees with the MAG Group, as applicable, to
        the extent such service is recognized by the MAG Group for the purpose
        of eligibility for leave entitlement under the MAG Leave of Absence
        Plans and FMLA; provided, however, that

                                      -14-

        no duplication of benefits shall, to the extent permitted by law, be

        Section 4.7 Workers' Compensation Plan.

               (a) Assumption of MAG and MercFuel Workers' Compensation Plan
        Liabilities by MercFuel. Effective as of the Separation Date, MercFuel
        shall assume and be solely responsible for all Liabilities relating to,
        arising out of, or resulting from their claims by MercFuel Employees and
        MercFuel Transferred Employees employment with the MercFuel Business
        ("MercFuel Claims") whether incurred before or after the Separation
        Date.

               (b) Participation in the MAG Workers' Compensation Plan. MercFuel
        shall, until the Distribution Date (or such other date as MercFuel and
        MAG may mutually agree), continue to be a Participating Company in the
        MAG Workers' Compensation Plan. MAG shall continue to administer, or
        cause to be administered, the MAG Workers' Compensation Plan in
        accordance with its terms and applicable law. MercFuel shall fully
        cooperate with MAG and its insurance company in the administration and
        reporting of MercFuel Claims under the MAG Workers' Compensation Plan.
        Any determination made, or settlement entered into, by or on behalf of
        MAG or its insurance company with respect to MercFuel claims under the
        MAG Workers' Compensation Plan shall be final and binding. MercFuel
        shall reimburse MAG and its insurance company for any and all direct and
        indirect costs related to the MercFuel claims or MercFuel's
        participation in the MAG Workers' Compensation Plan, including, but not
        limited to loss costs, claims administration fees, legal expenses,
        premium audits, and retrospective premium adjustments, subject to
        Section 6.2. MAG shall transfer to and reimburse MercFuel any assets
        related to the MercFuel claims or MercFuel's participation in the MAG
        Workers' Compensation Plan, including, but not limited to, loss
        reserves, premium audits, and retrospective premium adjustments.

               (c) Outsourcing of MercFuel Workers' Compensation Plan Claims.
        MercFuel shall have the right to transfer the administration of MercFuel
        Claims incurred under the MAG Workers' Compensation Plan to a third
        party administrator, vendor, or insurance company ("Outsource").
        MercFuel shall promptly notify MAG of its intent to transfer such
        claims, including the material terms and conditions of the transfer
        before the effective date thereof. MAG, upon the request of MercFuel,
        shall use its commercially reasonable best efforts to procure such
        Outsourcing on behalf of MercFuel, assist MercFuel in the transition to
        Outsourcing, and provide MercFuel with any information that is in the
        possession of MAG and is reasonably available and necessary to obtain

        of the Distribution Date, MercFuel shall be responsible for complying
        with the workers' compensation requirements of the states in which the
        MercFuel Group conducts business and for obtaining and maintaining
        insurance programs for its risk of loss. Such insurance arrangements
        shall be separate and apart from the MAG Workers' Compensation Plan.
        Notwithstanding the foregoing, MAG, upon the request of MercFuel, shall
        use its commercially reasonable best efforts to procure workers'
        compensation insurance policies on behalf of MercFuel, assist MercFuel
        in the transition to its own separate insurance program, and provide
        MercFuel with any information that is in the possession of MAG and is
        reasonably available and necessary to either obtain insurance coverages
        for MercFuel or to assist MercFuel in preventing unintended
        self-insurance, in whatever form.

        Section 4.8 Administrative Services. To the extent not provided
otherwise in this Article, MAG shall provide certain administrative services to
MercFuel in conjunction with both the MAG and MercFuel Health and Welfare Plans

        Section 5.1 Bonus Plan. Employees of the MercFuel Business (including,
for this purpose, any employees of MAG who are designated as employees of the
MercFuel Business for purposes of the Separation) shall cease their
participation in the MAG Bonus Plan in the quarter ending prior to the

Any bonus pool, or portion thereof, that has been finally determined by MAG in
its discretion or accrued for under the MAG Bonus Plan for the benefit of, or
that is allocable to, employees of the MercFuel Business (including for this
purpose, any employees of MAG who are designated as employees of the MercFuel
Business for purposes of the Separation) shall be paid to such Employees
pursuant to the terms and conditions of the MAG Bonus Plan, except that such
payment shall be made on the Distribution Date (or such other date as MAG and
MercFuel may mutually agree). Effective as of the Distribution Date (or such
other date as MAG and MercFuel may mutually agree), MercFuel shall establish the
MercFuel Bonus Plan for MercFuel Employees and MercFuel Transferred Employees
for MercFuel fiscal period(s) beginning on and after the Distribution Date (or
such other date as MAG and MercFuel may mutually agree), to be administered by
the Compensation Committee of the MercFuel Board of Directors.

        Section 5.2 MAG Options.

               (a) Option Assumption by MercFuel. At the Distribution Date (or
        such other date as MAG and MercFuel may mutually agree), 100 percent of
        each outstanding MAG Option held by MercFuel Transferred Employees,
        whether vested or unvested, shall be, in connection with the
        Distribution, assumed by MercFuel. MercFuel shall replace 100 percent of
        the total intrinsic value of each MAG Option held by MercFuel
        Transferred Employees as of the Distribution Date (or such other date as
        MAG and MercFuel may

                                      -16-
<PAGE>   24

        mutually agree) by offering options to purchase MercFuel stock mirroring
        the provisions of the then existing MAG Options. Each MAG Option so
        assumed by MercFuel shall continue to have, and be subject to, the same
        terms and conditions set forth in the MAG Stock Plans and as provided in
        the respective option agreements governing such MAG Option as of the
        Distribution Date (or such other date as MAG and MercFuel may mutually
        agree), except that (i) such MAG Option shall be exercisable for that
        number of whole shares of MercFuel common stock equal to the quotient of
        the number of shares of MAG common stock that were issuable upon
        exercise of such MAG Option as of the Distribution Date divided by the
        Ratio, rounded down to the nearest whole number of shares of MercFuel
        common stock, and (ii) the per share exercise price for the shares of
        MercFuel common stock issuable upon exercise of such assumed MAG Option
        shall be equal to the product determined by multiplying the exercise
        price per share of MAG common stock at which such MAG Option was
        exercisable as of the Distribution Date by the Ratio, rounded up to the
        nearest whole cent.

               (b) Assumption Criteria. It is the intention of MAG and MercFuel
        that the assumption of MAG Options by MercFuel pursuant to Subsection
        5.2(a) meet the following criteria: (i) the aggregate intrinsic value of
        the assumed MAG Options immediately after the assumption is not greater
        than such value immediately before the assumption; (ii) with respect to
        each such assumed MAG Option, the ratio of the exercise price per share
        to the MercFuel Stock Value of the assumed MAG Options immediately after
        the assumption is not less than the ratio of the exercise price per
        share to the MAG Stock Value immediately before the assumption; and
        (iii) the vesting and option term of the assumed MAG Options shall not
        be changed.

               (c) Certain Non-U.S. Optionees. Except as may otherwise be agreed
        upon by MAG and MercFuel and/or as set forth in Schedule 5.2, this
        Section 5.2 shall govern the treatment of MAG Options held by non-U.S.
        MercFuel Transferred Employees, if any.

        Section 5.3 Administrative Services. To the extent not provided
otherwise in this Article, MAG shall provide certain administrative services to
MercFuel in conjunction with both the MAG and MercFuel Stock Plans in such
manner and for such period as MAG and MercFuel may mutually agree. MercFuel
shall reimburse MAG for any and all direct and indirect costs and expenses
related thereto, subject to Section 6.2.

               (a) Expenses and Costs Chargeable to a Trust. Effective as of the

               (b) Contributions to Trusts. With respect to MAG Plans to which
        MercFuel Employees and MercFuel Transferred Employees make
        contributions, MAG shall use reasonable procedures to determine MercFuel
        Assets and Liabilities associated with each such Plan, taking into
        account such contributions, settlements, refunds and similar payments.

               (c) Allocation of Costs and Expenses. Except as otherwise
        provided in this Agreement, the Master Transitional Services Agreement,

        hereto in connection with the Separation, the IPO (including
        underwriting discounts and commissions), and the Distribution and costs
        and expenses of the parties hereto in connection with the Separation

        in connection with the Separation and the Distribution.

        Section 6.3 Transitional Staffing Services. MAG will provide certain
transitional staffing services and other services as MAG and MercFuel may
mutually agree, as set forth on Schedule 6.3; provided, however, that for
purposes of the Workers' Compensation Plan (as set forth in Section 4.8) the
Transitional Staffing Services Agreement for finance shall control, to MercFuel
in such manner and for such period as MAG and MercFuel may mutually agree.

        Section 6.4 Sharing of Participant Information. In addition to the
responsibilities and obligations of MAG and MercFuel specified in Exhibit I to
the Separation Agreement, MAG and MercFuel shall share, or cause to be shared,
all participant information that is necessary or appropriate for the efficient

during the respective periods applicable to such Plans as MercFuel and MAG may
mutually agree). MAG and MercFuel and their respective authorized agents shall,
subject to applicable laws of confidentiality and data protection, be given
reasonable and timely access to, and may make copies of, all information
relating to the subjects of this Agreement in the custody of the other party or
its agents, to the extent necessary or appropriate for such administration.

        Section 6.5 Reporting and Disclosure Communications to Participants.
While MercFuel is a Participating Company in the MAG Plans, MercFuel shall take,
or cause to be taken, all actions necessary or appropriate to facilitate the
distribution of all MAG Plan-related communications and materials to employees,
participants and beneficiaries, including (without limitation) summary plan
descriptions and related summaries of material modification(s), summary annual

except to the extent such costs are charged pursuant to Section 6.2 (or are
otherwise addressed in this Agreement) or pursuant to an Ancillary Agreement.
MercFuel shall assist MAG in complying with all reporting

as of the Separation Date and ending on such date as MAG and MercFuel may
mutually agree, MAG and MercFuel and their duly authorized representatives shall
have the right to conduct joint audits with respect to any vendor contracts that

Welfare Plans. The scope of such audits shall encompass the review of all
correspondence, account records, claim forms, canceled drafts (unless retained
by the bank), provider bills, medical records submitted with claims, billing
corrections, vendor's internal corrections of previous errors and any other
documents or instruments relating to the services performed by the vendor under

standards, audit methodology, auditing policy and quality measures, reporting
requirements, and the manner in which costs and expenses incurred in connection
with such audits will be shared.

        Section 6.7 Employee Identification Numbers. Until the Distribution Date
(or such other period as MAG and MercFuel may mutually agree), MAG and MercFuel
shall not change any employee identification numbers assigned by MAG. MAG and
MercFuel mutually agree to establish a policy pursuant to which employee
identification numbers assigned to either employees of MAG or MercFuel shall not
be duplicated between MAG and MercFuel.

        Section 6.8 Beneficiary Designation. Subject to Section 6.11, all
beneficiary designations made by MercFuel Employees and MercFuel Transferred
Employees for the MAG Plans shall be transferred to and be in full force and

each such applicable MercFuel Plan, until such beneficiary designations are
replaced or revoked by the MercFuel Employees and MercFuel Transferred Employee
who made the beneficiary designation.

        Section 6.9 Requests for IRS and DOL Opinions. MAG and MercFuel shall
make such applications to regulatory agencies, including the IRS and DOL, as may
be necessary or appropriate. MercFuel and MAG shall cooperate fully with one
another on any issue relating to the transactions contemplated by this Agreement
for which MAG and/or MercFuel elects to seek a determination letter or private
letter ruling from the IRS or an advisory opinion from the DOL.

        Section 6.10 Fiduciary Matters. MAG and MercFuel each acknowledge that
actions contemplated to be taken pursuant to this Agreement may be subject to
fiduciary duties or standards of conduct under ERISA or other applicable law,
and that no party shall be deemed to be in violation of this Agreement if such
party fails to comply with any provisions hereof based upon such party's good
faith determination that to do so would violate such a fiduciary duty or
standard.

        Section 6.11 Consent of Third Parties. If any provision of this
Agreement is dependent on the consent of any third party (such as a vendor) and
such consent is withheld, MAG and MercFuel shall use their commercially
reasonable best efforts to implement the applicable provisions of this
Agreement. If any provision of this Agreement cannot be implemented due to

                                      -19-
<PAGE>   27

the failure of such third party to consent, MAG and MercFuel shall negotiate in
good faith to implement the provision in a mutually satisfactory manner.

                           EMPLOYMENT-RELATED MATTERS

        Section 7.1 Terms of MercFuel Employment. All basic terms and conditions
of employment for MercFuel Employees and MercFuel Transferred Employees
including, without limitation, their pay and benefits in the aggregate, shall,
to the extent legally and practicably possible, remain substantially the same

when the MercFuel Employee or MercFuel Transferred Employee was employed by the
MAG Group, as applicable. Notwithstanding the foregoing, MercFuel Employees and
MercFuel Transferred Employees may be required to execute a new agreement
regarding confidential information and proprietary developments in a form
approved by MercFuel by the Separation Date. In addition, nothing in the
Separation Agreement, this Agreement, or any Ancillary Agreement should be
construed to change the at-will status of the employment of any of the employees
of the MAG Group or the MercFuel Group.

        Section 7.2 HR Data Support Systems. MAG shall provide human resources
data support for MercFuel Employees and MercFuel Transferred Employees through

the Separation Agreement, MAG and MercFuel each agree not to solicit or recruit,

for a period of two (2) years following the Distribution Date. Notwithstanding
the foregoing, this prohibition on solicitation does not apply to actions taken
by a party either:

               (a) solely as a result of an employee's affirmative response to a
        general recruitment effort carried out through a public solicitation or
        general solicitation, or (b) as a result of an employee's initiative.

        Section 7.4 Employment of Employees with U.S Work Visas. MercFuel
Employees with U.S. work visas authorizing them to work for MercFuel will
continue to hold work authorization for the MercFuel Group after the Separation

authorizing them to work for MAG, excluding the MercFuel Group, to request
authorization to work for MercFuel.

        Section 7.5 Confidentiality and Proprietary Information. No provision of
the Separation Agreement or any Ancillary Agreement shall be deemed to release
any individual for any violation of the MAG non-competition guideline or any
agreement or policy pertaining to confidential or proprietary information of any
member of the MAG Group, or otherwise relieve any individual of his or her
obligations under such non-competition guideline, agreement, or policy.

Employees' active employment by, leave of absence from, or termination of
employment with MercFuel, and (b) are necessary to administer and maintain

indirect costs and expenses associated with such delivery, subject to Section

        reasonable best efforts to cause MercFuel to receive service from MAG's
        third party unemployment insurance administrator through the
        Distribution Date (or such other date as MAG and MercFuel may mutually
        agree). MercFuel shall reimburse MAG for its allocable share of fees

        unemployment insurance administrator for services rendered during such
        period, pursuant to the Master Transitional Services Agreement. MercFuel

        efforts for and on behalf of MercFuel to procure an agreement with its

        insurance agreement, including, without limitation, administration of
        all unemployment compensation claims of MercFuel Transferred Employees
        and MercFuel Employees, regardless of whether such claims were filed
        before, on, or after the Distribution Date. MercFuel shall not
        unreasonably withhold its consent to adopt such an agreement with such
        administrator. MercFuel shall reimburse MAG for any and all direct and
        indirect costs and expenses associated with such procurement, subject to
        the Master Transitional Services Agreement.

        Section 7.9 Non-Termination of Employment; No Third-Party Beneficiaries.
No provision of this Agreement, the Distribution Agreement, or any Ancillary
Agreement shall be construed to create any right or accelerate entitlement to
any compensation or benefit whatsoever

                               DISPUTE RESOLUTION

        Section 6.1 Mediation. If a dispute, controversy or claim ("Dispute")
arises between the parties relating to the interpretation or performance of this
Agreement appropriate senior executives of each party who shall have the
authority to resolve the matter shall meet to attempt in good faith to negotiate
a resolution of the Dispute prior to pursuing other available remedies. The
initial meeting between the appropriate senior executives shall be referred to
herein as the "Dispute Resolution Commencement Date". Discussions and
correspondence relating to trying to resolve such Dispute shall be treated as
Confidential Information developed for the purpose of settlement and shall be
exempt from discovery or production and shall not be admissible. If the senior
executives are unable to resolve the Dispute within thirty (30) days from the
Dispute Resolution Commencement Date, and either party wishes to pursue its
rights relating to such Dispute, then the Dispute will be mediated by a mutually
acceptable mediator appointed within thirty (30) days after written notice by
one party to the other demanding non-binding mediation. Neither party may
unreasonably withhold consent to the selection of a mediator or the location of
the mediation. Both parties will share the costs of the mediation equally,
except that each party shall bear its own costs and expenses, including
attorneys' fees, witness fees, travel expenses, and preparation costs. The
parties may also agree to replace mediation with some other form of non-binding
or binding alternate dispute resolution ("ADR").

        Section 6.2 Arbitration. Any Dispute which the parties cannot resolve
through mediation within ninety (90) days of the Dispute Resolution Commencement
Date, unless otherwise mutually agreed, shall be submitted to final and binding
arbitration under the then

                                       5
<PAGE>   9

current Commercial Arbitration Rules of the American Arbitration Association
("AAA"), by three (3) arbitrators in Los Angeles County, California. Such
arbitrators shall be selected by the mutual agreement of the parties or, failing
such agreement, shall be selected according to the aforesaid AAA rules. The
arbitrators will be instructed to prepare and deliver a written, reasoned
opinion stating their decision within thirty (30) days of the completion of the
arbitration. The prevailing party in such arbitration shall be entitled to
expenses, including costs and reasonable attorneys' and other professional fees,
incurred in connection with the arbitration (but excluding any costs and fees
associated with prior negotiation or mediation). The decision of the arbitrator
shall be final and non-appealable and may be enforced in any court of competent
jurisdiction. The use of any ADR procedures will not be construed under the
doctrine of laches, waiver or estoppel to adversely affect the rights of either
party.

        Section 6.3 Court Action. Any Dispute regarding the following is not
required to be negotiated, mediated or arbitrated prior to seeking relief from a
court of competent jurisdiction: breach of any obligation of confidentiality;
infringement, misappropriation, or misuse of any intellectual property right;
any other claim where interim relief from the court is sought to prevent serious
and irreparable injury to one of the parties or to others. However, the parties
to the Dispute shall make a good faith effort to negotiate and mediate such
Dispute, according to the above procedures, while such court action is pending.

        Section 6.4 Continuity of Service and Performance. Unless otherwise
agreed in writing, the parties will continue to provide service and honor all
other commitments under this Agreement during the course of dispute resolution
pursuant to the provisions of this Article 6 with respect to all matters not
subject to such dispute, controversy or claim.

                                   ARTICLE VII
                             LIMITATION OF LIABILITY

        IN NO EVENT SHALL EITHER PARTY OR ITS SUBSIDIARIES BE LIABLE TO THE
OTHER PARTY OR ITS SUBSIDIARIES FOR ANY SPECIAL, CONSEQUENTIAL, INDIRECT,
INCIDENTAL OR PUNITIVE DAMAGES OR LOST PROFITS, HOWEVER CAUSED AND ON ANY THEORY
OF LIABILITY (INCLUDING NEGLIGENCE) ARISING IN ANY WAY OUT OF THIS AGREEMENT,
WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES;
PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATIONS SHALL NOT LIMIT EACH PARTY'S
OBLIGATIONS EXPRESSLY ASSUMED IN EXHIBIT J OF THE MASTER SEPARATION AND
DISTRIBUTION AGREEMENT; PROVIDED FURTHER THAT THE EXCLUSION OF PUNITIVE DAMAGES
SHALL APPLY IN ANY EVENT.

                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

        Section 8.1 Disclaimer. EACH PARTY ACKNOWLEDGES AND AGREES THAT ALL

Subsidiaries makes any warranty or representation that any manufacture, use,

infringement of any Patent or other intellectual property right of any Third
Party.

        Section 8.2 No Implied Licenses. Nothing contained in this Agreement
shall be construed as conferring any rights by implication, estoppel or
otherwise, under any intellectual property right, other than the rights
expressly granted in this Agreement with respect to the MercFuel Technology.
Neither party is required hereunder to furnish or disclose to the other any
technical or other information, except as specifically provided herein.

        Section 8.3 Infringement Suits. Neither party shall have any obligation
hereunder to institute any action or suit against Third Parties for infringement
of any Copyrights or Mask Work Rights or misappropriation of any trade secret
rights in or to any Technology licensed to the other party hereunder, or to
defend any action or suit brought by a Third Party which challenges or concerns
the validity of any of such rights or which claims that any Technology assigned
or licensed to the other party hereunder infringes any Patent, Copyright, Mask
Work Right or other intellectual property right of any Third Party or
constitutes a misappropriated trade secret of any Third Party. MAG shall not
have any right to institute any action or suit against Third Parties for
infringement of any of the Copyrights or Mask Work Rights in or to the MercFuel
Technology.

        Section 8.4 No Other Obligations. NEITHER PARTY ASSUMES ANY
RESPONSIBILITIES OR OBLIGATIONS WHATSOEVER, OTHER THAN THE RESPONSIBILITIES AND
OBLIGATIONS EXPRESSLY SET FORTH IN THIS AGREEMENT OR A SEPARATE WRITTEN

agreements and understandings with respect to the subject matter hereof and
thereof. This Agreement shall prevail in the event of any conflicting terms or
legends which may appear on any portion of the MercFuel Technology. To the
extent that the parties enter into specific agreements regarding specific
projects, such agreements shall supersede this Agreement with respect to any
common subject matter.

        Section 8.6 Governing Law. This Agreement shall be construed in
accordance with and all Disputes hereunder shall be governed by the laws of the
State of California, excluding its conflict of law rules and the United Nations
Convention on Contracts for the International Sale of Goods. The Superior Court
of Los Angeles County and/or the United States District Court for the Southern
District of California shall have jurisdiction and venue over all Disputes
between the parties that are permitted to be brought in a court of law pursuant

or to such other address as the party to whom notice is given may have
previously furnished to the other in writing as provided herein. Any notice
involving non-performance or renewal shall be sent by hand delivery, recognized
overnight courier or, within the United States, may also be sent via certified
mail, return receipt requested. All other notices may also be sent by fax,
confirmed by first class mail. All notices shall be deemed to have been given
and received on the earlier of actual delivery or three (3) days from the date
of postmark.

        Section 8.9 Nonassignability. Neither party may, directly or indirectly,
in whole or in part, whether by operation of law or otherwise, assign or
transfer this Agreement, without the other party's prior written consent, and
any attempted assignment, transfer or delegation without

                                       8
<PAGE>   12

such prior written consent shall be voidable at the sole option of such other
party. Notwithstanding the foregoing, each party (or its successive assignees or
transferees hereunder) may, without such consent, assign this Agreement to an
entity that succeeds to all or substantially all of the business or assets of
such party as long as such Person agrees to accept all of the terms set forth
herein; provided, however, that the rights and obligations set forth in Section
3.1 may not be assigned or transferred in any event (except in the case of a
reincorporation of such party in another state). Without limiting the foregoing,
this Agreement will be binding upon and inure to the benefit of the parties and
their permitted successors and assigns.

        Section 8.10 Severability. If any term or other provision of this
Agreement is determined by a court, administrative agency or arbitrator to be
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to either party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that the transactions contemplated hereby are fulfilled to the fullest
extent possible.

        Section 8.11 Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of either party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude other or
further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

        Section 8.12 Amendment. No change or amendment will be made to this
Agreement except by an instrument in writing signed on behalf of each of the
parties to such agreement.

        Section 8.13 Counterparts. This Agreement, including the Ancillary
Agreements and the Exhibits and Schedules hereto and thereto and the other
documents referred to herein or therein, may be executed in counterparts, each
of which shall be deemed to be an original but all of which shall constitute one
and the same agreement.

        WHEREFORE, the parties have signed this Master Technology Ownership and
License Agreement effective as of the date first set forth above.
