           -------
commercially reasonable best efforts to assist RS in its efforts to transition

approval shall not be unreasonably delayed, conditioned or withheld, regarding
the transactions contemplated herein and other aspects of RS's business
relationship with AOL and/or MF.

      2.3  MF Liability.  MF acknowledges and agrees that MF (and not RS) will
           ------------
be solely responsible for any costs or expenses MF incurs in implementing the
cessation of the *** as contemplated by this Agreement. Except as otherwise

to the cessation of the *** as contemplated by this Agreement. Additionally, as
between MF and Exhibitors, and without prejudice to RS's obligations hereunder
(including its obligations under Section 10.1), MF remains obligated and liable

                            SERVICES AND TRANSITION

      3.1  Services.  Beginning on the Effective Date, as a subcontractor of MF
           --------
and under the direction of MF as provided herein, RS shall perform all services
required to be provided to (i) Exhibitors (other than *** ("***")) but only
under Sections 3, 5, 5.1, 5.2, 5.3, 5.4 and 5.5 of the Exhibitor Agreements
(other than the Exhibitor Agreement between *** and MF) and (ii) *** but only
under Sections 2, 4.1, 4.2, 4.3, 4.4, 4.5 and 4.6 of the Exhibitor Agreement
between *** and MF (collectively, all such sections shall be referred to as
"Sections") (the "Services"). Irrespective of what may be contained in the
Sections, the Services do not include providing training services of any kind to
the Exhibitors or their employees, agents or representatives. Services shall be
performed in accordance with, and RS shall comply with the terms and conditions
of, the Sections including any standards of care and performance set forth
therein, but in each case in no event less than a professional and timely manner
and consistent with similar types of services provided by RS to its customers.
MF shall have the right to terminate the Services upon thirty (30) days prior
written notice to RS, but only in the event of an uncured material breach of the
Services by RS. With respect to the Exhibitor Agreements, at a time designated
by mutual agreement of MF and RS, MF shall issue written notices to the
Exhibitors advising them that the service term under the Exhibitor Agreements
will not be renewed beyond the then-current term and that all services provided
under the Sections will cease upon expiration of the then-current service term.
Additionally, MF shall issue whatever additional notices are required under the
Exhibitor Agreements to facilitate the non-renewal of such service terms. If an
Exhibitor other than *** requests Services pursuant to Section 5.4 of its

will not be supported beyond the then-current term of

its Exhibitor Agreement and use commercially reasonable efforts to convince the
Exhibitor to migrate to the Enhanced RS POS System instead.

      3.2  Transition Services.  MF and RS shall cooperate to implement the
           -------------------
transition plan attached hereto as Exhibit D ("Transition Plan") within the time
periods set forth therein.

      3.3  Staffing Needs.  MF acknowledges and understands that RS requires a
           --------------
reasonable level of MF MARS System help desk staffing (sufficient to meet then
current needs, but not greater than as of the Effective Date) to assist RS in
performing the Services through a transition period extending from the Effective
Date through September 30, 2001 (the "Transition Period"), and MF agrees to
offer its help desk personnel retention packages, stay bonuses, and other
financial incentives ("Compensation") to encourage such personnel to provide the
Services during the Transition Period.  If MF terminates any such personnel
during the Transition Period, unless such personnel are not required to meet
then current needs or the Parties agree otherwise, MF shall use commercially
reasonable efforts to replace such personnel promptly with qualified personnel
for the duration of the Transition Period.  MF, and not RS, shall have and
assume any liability to such personnel for Compensation payable by MF to such
personnel, notwithstanding that one or more of the help desk personnel may
become employees of RS during the Transition Period.

      3.4  Migration of Exhibitors.  Beginning on the Effective Date, RS shall
           -----------------------
promptly use commercially reasonable best efforts to ***, although nothing
herein shall be deemed or construed as a representation or guarantee by RS as to
the success it will have in ***. Except as specifically provided herein, MF
shall have no obligations regarding the migration or transitioning of any
Exhibitor to or from the MARS System. In the event any Exhibitor migrates to RS
products from the MARS System, MF agrees to permit such Exhibitor to voluntarily
terminate, without liability or cause, the Exhibitor's Exhibitor Agreement.

      3.5  Amendment to Marketing and Development Agreement. Contemporaneously
           ------------------------------------------------

amendment in substantially the form attached hereto as Exhibit E to that certain

           ---------------------------------------
contractor. RS shall not be deemed for any purpose to be an employee of MF.

remain employees of MF, MF shall not be responsible to RS or any governing body
for any payroll-related taxes related to the performance of the Services,
including but not limited to, withholding

or other taxes related to federal or state income tax, social security benefits
or unemployment compensation. RS and MF further represent and warrant that
neither Party is an agent, representative or partner of the other Party. Neither
Party shall have any right, power or authority to enter into any agreement for
or on behalf of, or incur any obligation or liability on behalf of, or to
otherwise bind, the other Party. This Agreement shall not be interpreted or
construed to create an employment relationship, an association, agency, joint
venture or partnership between the Parties or to impose any liability
attributable to such a relationship upon either Party.

      4.2  Use of Independent Contractors by RS.  Any independent contractor
           ------------------------------------
used by RS in connection with the Services (regardless of the amount of time
spent by such independent contractor in providing Services) shall have the
requisite skill level to satisfy the standards of care and performance set forth
in Section 3.1 and shall be either (i) a bona fide employee of a third party
with which RS has arranged for such employee to provide the Services or (ii) a
bona fide independent contractor who meets the requirements of the Internal
Revenue Service for independent contractor status. RS shall be fully and solely
responsible for the supervision and payment of such independent contractors and
for the work performed by such independent contractors.

      4.3  Payroll and Other Employment Taxes.  RS, and not MF, shall be
           ----------------------------------
responsible for payment of compensation to RS's employees and independent
contractors; payroll deductions required by federal, state or local law;
payments for income tax, social security and Medicare contributions,
unemployment or disability insurance as required by law; and workers'
compensation insurance, coverage or premiums required under state law; all as in
effect from time to time. At no time shall either Party be deemed to be the
employer of the other Party's employees or independent contractors, even if such
Party's personnel may supervise the other party's employees or independent
contractors.

shall act as a liaison between such Party and the other Party.

           -----------------------------
("Report") to MF's Manager on a monthly basis for the initial six (6) months of
the Term and on a quarterly basis thereafter during the Term. Such Reports shall
be in a form mutually acceptable to RS and MF, and shall detail the Services
provided to Exhibitors and RS's migration activity during the reporting period.
If MF so requests, the Managers shall hold status meetings in order to review
the information described in a Report.

      6.1  Payment.
           -------
           (a)  In consideration of RS' obligations under this Agreement, and

      to RS the sum of *** in *** installments as follows:

          *** on ***;

          *** on or before ***; and

          *** on or before ***.

     The *** to be paid by MF hereunder is consistent with the performance of
     Services and delivery of licenses as contemplated hereunder.  RS shall
     apply portions of such payment as follows:  (i) *** to subsidize the
     credits to be provided pursuant to that certain letter agreement with ***
     of even date herewith (which RS shall enter into and comply with), and (ii)
     *** to subsidize credits that RS shall make available to any Exhibitors
     other than *** that enter into agreements after the Effective Date,
     pursuant to which agreements the Exhibitors are to receive licenses with
     respect to the Enhanced RS POS System, and which credits shall be applied
     by RS to any payments due to RS for such licenses through September 30,
     2001; provided that RS shall not apply any of the foregoing credits to any
     Exhibitor unless such Exhibitor agrees with MF to terminate its Exhibitor
     Agreement, as to the relevant movie theater(s), as of the time each theater
     no longer uses the MARS System. The Parties acknowledge that RS' obligation
     to provide Services with respect to such movie theater shall terminate at
     the same time. In the event that the foregoing credits are not used within
     the times applicable thereto, RS shall have no further obligation to MF
     concerning the application of such payment and RS shall have unfettered use
     of such funds.

          (b)  MF shall make the payment required by Section 6.1(a) by wire

          Account Number:  000001058908

          (c)  Pursuant to a binding purchase order executed by AOL on December
     20, 2000 in connection with certain services rendered by RS to MF during
     October, November and December, 2000 with respect to a transition of MF's
     MARS business, MF shall include, along with the payment due on the
     Effective Date, an additional ***.

          (d)  In connection with the Services, MF shall use its commercially
     reasonable best efforts to cause Exhibitors to pay directly to RS all
     amounts due to MF from Exhibitors under the Exhibitor Agreements for the
     performance of Services, including any license fees for use of the MARS
     System and any expenses that may be reimbursable under the Exhibitor
     Agreements for the performance of such Services. To the extent that
     Exhibitors are required or agree to do so, RS shall be responsible for
     invoicing such Exhibitors for such amounts, and RS shall bear the risk of
     collecting such amounts from Exhibitors, provided, however, if the
     Exhibitors pay any such amounts to MF notwithstanding their agreement to
     pay RS directly, MF shall promptly deliver such monies to RS, without
     offset or reduction for any reason. To the extent that Exhibitors are not
     required, or do not agree, to pay directly to RS all amounts due to MF
     under the Exhibitor Agreements for the performance of Services, without
     offset or reduction for any reason, MF shall deliver to RS all such amounts
     received by MF from Exhibitors, on a monthly basis, within ten (10)
     business days after the end of the month. In such case, RS shall identify
     to MF on a monthly basis any expenses that may be reimbursable under the
     Exhibitor Agreements for the performance of such Services so that MF can
     invoice the Exhibitors therefor in accordance with the terms of the
     relevant Exhibitor Agreements. In either case, if any Exhibitor fails to
     pay any such amounts as required under its Exhibitor Agreement, MF shall
     cooperate with RS in providing notice thereof to such Exhibitor, and if
     appropriate, in terminating (after obtaining RS's approval for such
     termination) such Exhibitor Agreement in accordance with its terms. To the
     extent that either Party receives before the Effective Date advance
     payments under the Exhibitor Agreements for services to be provided after
     the Effective Date, the receiving Party shall, within thirty (30) days
     after the Effective Date, pay to the other Party a prorated portion of such
     payments corresponding to the portion of the Services period undertaken or
     to be undertaken by the other Party. Notwithstanding the foregoing, MF may
     deduct from its payments to RS certain costs as provided in Section 7.1(d).

     6.2  Expenses.  To the extent Exhibitor Agreements require prior approval
          --------
of expenses in order for such expenses to be reimbursed, MF will cooperate with
RS and use its commercially reasonable best efforts to acquire such prior
approval, but in no event shall MF be responsible for reimbursing expenses not
collected by RS (unless such expenses were mistakenly paid to MF) from
Exhibitors, irrespective of whether prior approval was timely sought or
obtained.

          --------
reimbursable expenses payable by MF and not paid to RS when due at the lesser of
the maximum amount chargeable by law or 1.0% per month commencing with the date
the payment was due.

      6.4  Records.  RS shall maintain complete and accurate accounting records
           -------
of all reimbursable expenses, in a form in accordance with generally accepted
accounting principles, to substantiate RS's expenses hereunder and RS shall
retain such records for a period of four (4) years from the date of the relevant
expense. MF shall maintain complete and accurate accounting records of all
amounts received from Exhibitors under the Exhibitor Agreements in a form in
accordance with generally accepted accounting principles, and MF shall retain
such records for a period of four (4) years from the date of the relevant
payment.

      6.5  Taxes.  The Service Fees and expenses payable by MF and due to RS are
           -----
net amounts to be received by RS, exclusive of all sales, use, withholding,
excise, value added and other taxes incurred by MF or imposed on RS in the
performance of the Services. Each party is responsible for determining and
paying any taxes based upon its own net income.

      specifications, and such other documentation used in the ordinary course
      by MF's computer programmers to create derivative works based on the MARS
      Software or used by MF to provide software and

      hardware support and maintenance services under the Exhibitor Agreements.
      Additionally, MF shall assist RS in establishing a software development
      environment for each currently licensed and supported version of the MARS
      Software and shall provide assistance as necessary to ensure RS is able to
      use these environments.

           (d)  Hardware.  For seventy-five (75) days after the Effective Date,
                --------
      MF shall be responsible for shipping replacement parts for the MARS
      Hardware to Exhibitors who are entitled to receive such parts as a part of
      the Services. RS shall be responsible for all of MF's costs of doing so
      (including but not limited to costs of MARS Hardware procured after the
      Effective Date (but not before the Effective Date), personnel and
      shipping). MF shall have the right to deduct such costs from the amounts
      payable by MF to RS pursuant to Section 6.1(d). At the end of such
      seventy-five (75) day period, at no charge to RS, MF shall deliver all of
      its then current inventory of replacement parts for the MARS Hardware and,
      during the period RS is providing Services hereunder, MF shall use all
      reasonable efforts to provide guidance and assistance to RS and respond to
      questions posed by RS, regarding hardware maintenance services for the
      MARS Hardware and help RS obtain a sufficient supply of parts for the MARS
      Hardware throughout the Term including, without limitation, introducing RS
      to its suppliers, calling upon and recommending that such suppliers do
      business with RS and otherwise acting in a commercially reasonable manner
      to facilitate RS accomplishing the foregoing.

      7.2  Enhancements.
           ------------

           (a)  Proprietary Rights.  RS agrees that MF is the sole and exclusive
                ------------------
     owner of all right, title and interest in and to any Enhancements created
     by RS and its employees and independent contractors, including all patent,
     copyright, trade secret and other proprietary rights therein that may be
     secured in any place under laws now or hereafter in effect. The parties
     intend that any Enhancements created by RS and its employees and
     independent contractors shall be deemed "works made for hire" within the
     meaning of the copyright laws of the United States and any similar laws of
     other jurisdictions. To the extent, if any, that RS, its employees or
     independent contractors have rights in such Enhancements notwithstanding
     the foregoing, RS hereby irrevocably assigns to MF, and agrees that MF
     shall be the sole and exclusive owner of, all right, title and interest in
     and to such Enhancements, including all patent, copyright, trade secret and
     other proprietary rights therein that may be secured in any place under
     laws now or hereafter in effect. The source code for the MARS System and
     any Enhancements thereof shall be Confidential Information of MF. RS shall
     have valid and enforceable agreements with all of its employees and
     independent contractors providing Services containing a nondisclosure
     obligation comparable in scope to Article 8 and giving RS all rights and
     authority necessary to effectuate the provisions of this Article 7.

                                      -10-

           (b)  Delivery.  Promptly after each significant Enhancement, RS shall
                --------
     deliver to MF: (i) one (1) machine-readable copy of the object code for the
     MARS Software, including such Enhancement; (ii) two (2) copies of the
     documentation or other materials that RS has updated to reflect such
     Enhancement; (iii) the source code for the MARS Software including such
     Enhancement; and (iv) any existing technical documentation, program
     specifications, and such other documentation pertaining to the creation of
     such Enhancement.

     7.3  Further Assurances.  Upon the request of MF, RS shall sign and deliver
          ------------------
any assignments or other necessary documents and otherwise assist MF to obtain,
maintain, perfect or enforce any of MF's rights under Section 7.2(a).

                                CONFIDENTIALITY

      8.1  Confidentiality Obligation.  A Party (the "Receiving Party") shall
           --------------------------
keep, and shall cause its Affiliates to keep, strictly confidential any
information disclosed by the other Party (the "Disclosing Party") or otherwise
made available to the Receiving Party concerning any Party's performance of this
Agreement or otherwise concerning the business, operations, marketing or trade
secrets or other proprietary information of the Disclosing Party (whether in
written media or otherwise) ("Confidential Information"), using at least the
same degree of care that it uses to protect its own confidential or proprietary
information. "Confidential Information" shall not include information: (a) that
is or becomes generally available to the public other than as a result of
disclosure thereof by the Receiving Party; (b) that is lawfully received by the
Receiving Party on a nonconfidential basis from a third party that is not itself
under any obligation of confidentiality or nondisclosure to the Disclosing Party
or any other Person with respect to such information; or (c) that by written
evidence can be shown by the Receiving Party to have been independently
developed by the Receiving Party.

      8.2  Nondisclosure of Confidential Information.  The Receiving Party shall
           -----------------------------------------
use Confidential Information solely for the purposes of this Agreement and shall
not disclose or disseminate any Confidential Information to any Person at any
time, except for disclosure to those of its Affiliates, and their respective
directors, officers, employees, independent consultants, accountants, attorneys,
advisers and agents whose duties reasonably require them to have access to such
Confidential Information, provided that such directors, officers, employees,
accountants, attorneys, advisers and agents are bound to maintain the
confidentiality of such Confidential Information to the same extent as if they
were Parties hereto.

      8.3  Nondisclosure of Agreement. In addition to the obligations set forth
           --------------------------
in Section 8.1 above, neither Party shall disclose this Agreement or any
provisions of this Agreement and, without the prior consent of the other Party,
no Party shall make any press release or other public announcement of or
otherwise disclose this Agreement or any of its provisions to any third party:

                                      -11-
<PAGE>

           (a)  Other than to its Affiliates and to its own and its Affiliates'
directors, officers, employees, attorneys and accountants whose duties
reasonably require familiarity with such Agreement, provided that (i) the
Disclosing Party informs such Affiliates, directors, officers, employees,
accountants, attorneys, advisers, agents and independent contractors of the
confidential nature of such Agreement and instructs such Persons to comply with
the confidentiality and nondisclosure obligations of this Section 8.3 and (ii)
the Disclosing Party is responsible for any breach or violation by such Persons
of the confidentiality and nondisclosure obligations of this Section 8.3;

           (b)  Other than to third parties providing debt financing to any
Party or any of its Affiliates and to the lead underwriter engaged in connection
with any offering of securities any Party or any of its Affiliates, provided
that such Persons enter into a customary form of confidentiality agreement with
such Party that includes this Agreement as confidential information subject to
the confidentiality and nondisclosure obligations set forth therein; and

           (c)  With respect to this Agreement, except for such disclosure as
may be required by applicable law or regulation or pursuant to the rules of or a
listing agreement with a national securities exchange or the NASDAQ National
Market, in which case the Disclosing Party shall provide the other Parties with
sufficient advance notice of such disclosure so that the other Parties have the
opportunity, if they so desire, to restrict such requirement for disclosure,
seek a protective order or take another appropriate remedy; provided that, in
connection with any offering of securities of the Disclosing Party or any of its
Affiliates, the Disclosing Party shall provide in advance to the other Parties
hereto for review the form and content of any disclosure of this Agreement or
any of its provisions that may be required by applicable law or regulation which
discuss such other Party and shall include such modifications to such disclosure
as may be reasonably requested by such other Party (except that the Disclosing
Party may file this Agreement as an exhibit to its registration statement or
required periodic reports if it would constitute a "material agreement" under
applicable law or regulation and the Disclosing Party shall use commercially
reasonable efforts to obtain confidential treatment of the portions of this
Agreement that meet the SEC qualifications for confidential treatment if so
requested by such other Party).

      8.4  Exception.  The foregoing confidentiality and nondisclosure
           ---------
obligations shall not apply to Confidential Information that is required to be
publicly disclosed by law or by regulation; provided, however, that, in such
event, the Receiving Party provides the Disclosing Party with prompt advance
notice, to the extent practicable, of such disclosure so that the Disclosing
Party has the opportunity if it so desires to restrict such requirement for
disclosure, seek a protective order or take another appropriate remedy. In any
event, the Receiving Party shall use commercially reasonable efforts to secure
confidential treatment of any Confidential Information of the Disclosing Party
that it is required to disclose.

                                      -12-
<PAGE>

      8.5  Injunctive Relief.  Each of MF and RS acknowledges that disclosure of
           -----------------
any Confidential Information by it will give rise to irreparable injury to the
other Party, its Affiliates or the owner of such information, inadequately
compensable in damages. Accordingly, such other Party or party may seek and
obtain injunctive relief against the breach or threatened breach of the
foregoing undertakings, in addition to any other legal remedies which may be
available. Each of MF and RS acknowledges and agrees that the covenants
contained herein are necessary for the protection of legitimate business
interests of the other Party and its Affiliates and are reasonable in scope and
content.

      8.6  Survival.  The confidentiality and nondisclosure obligations of this
           --------
Article 8 shall survive the termination or expiration of this Agreement and
remain in effect for a period of two years following the termination or
expiration of this Agreement except that with respect to any item protected
thereunder which constitutes a trade secret under applicable law (including the
source code of the MARS Software), such obligations of confidentiality shall
continue in effect with respect to such item for the maximum period permitted
under applicable law.

arising out of or resulting from: (i) any actual or alleged breach by RS of any
of its representations or warranties under this Agreement; (ii) RS's performance
of, or failure to perform, the Services; (iii) any actual or alleged
infringement of any patent, copyright, trademark, trade name, trade secret, or

specifications provided by MF which such infringement otherwise could not
reasonably have been avoided by RS; and (iv) RS's actions in connection with the

            ---------------
Affiliates, and its and their respective directors, officers, employees and
agents (collectively, the "RS Indemnitees"), from and against any Losses
incurred, arising out of or resulting from (i) any actual or alleged breach by
MF of any of its representations or warranties under this Agreement; (ii) any
actual or alleged infringement of any patent, copyright, trademark, trade name,

result from the modification of the foregoing by such RS Indemnitee or its

      10.3  Procedure.  Any MF Indemnitee or RS Indemnitee (each an
            ---------
"Indemnitee") shall notify the indemnifying Party promptly in writing of an
indemnifiable claim or cause of action under Section 10.1 or 10.2 upon receiving
notice or being informed of the existence thereof; provided, however, that
failure to notify the indemnifying Party of an indemnifiable claim or cause of
action shall not relieve the indemnifying Party of its obligation to provide
indemnification hereunder except to the extent that such failure prejudices the
indemnifying Party's ability to defend or settle such claim or cause of action.
The indemnifying Party shall assume, at its cost and expense, the sole defense
of such claim or cause of action through counsel selected by the indemnifying
Party that is reasonably acceptable to the Indemnitees. The Indemnitees shall
cooperate in the defense of such claim or cause of action and may retain
separate counsel at their sole cost and expense (except that the indemnifying
Party shall be responsible for the fees and expenses of the separate co-counsel
to the extent that the Indemnitees reasonably conclude that the counsel selected
by the indemnifying Party has a conflict of interest). The indemnifying Party
shall maintain control of such defense, including any decision as to settlement,
provided that the indemnifying Party shall not, without the Indemnitees' prior
written consent, compromise or settle any claim, suit or proceeding if such
compromise or settlement would impose an injunction or other relief upon the
Indemnitees or if such compromise or settlement does not include as an
unconditional term thereof the claimant's release of the Indemnitees from all
liability relating to such claim, suit or proceeding. The indemnifying Party
shall bear the total costs of any court award or any settlement of such claim or
cause of action approved by the indemnifying Party and all other costs, fees and
expenses related to the resolution thereof (including reasonable attorneys'
fees, except for attorneys' fees for which the Indemnitees are responsible).

MISREPRESENTATION UNDER THIS AGREEMENT, (1) NO PARTY SHALL BE LIABLE TO THE
OTHER PARTIES HEREUNDER FOR ANY INCIDENTAL, INDIRECT, SPECIAL, EXEMPLARY,
CONSEQUENTIAL OR PUNITIVE DAMAGES, AND (2) NEITHER PARTY'S TOTAL LIABILITY
HEREUNDER SHALL EXCEED ***.

                                     -----

     WHEREAS, MF, AOL and RS have previously entered into the MDA and the SPA.
The Parties wish to amend the MDA and the SPA as described in this Amendment

        work together in the future, but neither Party shall be obligated to the
        other with respect to such intention.

2.      RS Covenant.  If RS is in compliance in all material respects with the
        -----------
        terms and conditions of the MDA and that certain Services Agreement by

        Effective Date of the MDA and RS shall be relieved of, and released and
        discharged from, any obligations it ever had under Section 4.9 of the
        MDA. If as of the RS Covenant Expiration Date, MF shall have issued to
        RS a written notice of breach
<PAGE>

        or nonperformance under the MDA or Services Agreement, then RS shall
        have the right to cure such breach or nonperformance within sixty (60)
        days of its receipt of such written notice and should RS cure such
        breach or nonperformance, the Parties agree that the RS Covenant
        Expiration Date shall be deemed the date on which such cure is effected.

3.      Release.  Each Party, effective upon the Amendment Effective Date,
        -------
        hereby releases and discharges each other Party and each of their
        respective affiliates, and each of their respective agents, officers,
        directors, shareholders, employees, attorneys and representatives, as
        well as their respective successors and assigns, from all actions,
        causes of action, suits, claims, damages, losses, liabilities, and
        demands whatsoever, of whatever kind or nature, in contract or in tort,
        in law or equity, pursuant to federal, state or local statute, rule,
        ordinance or regulation, known or unknown, vested or contingent, matured
        or unmatured, disputed or undisputed, which the Party or any party
        claiming by or through the Party, ever had, or now has, for, upon or by
        reason of any breach of the MDA, from the beginning of the world until
        the Amendment Effective Date; provided that any claim for
        indemnification that a Party may have pursuant to Article XI of the MDA
        shall not be released hereby.

        -------------------------------
        hereby relieved of, and released and discharged from, any obligations it
        has ever had under the following provisions of the MDA: Article 2
        (except the last two sentences of Section 2.2), Section 3.8, Section
        4.2, Section 4.3, the second part of the initial sentence of Section 4.7
        commencing with ", provided that", Section 4.14 and Section 6.1.3.
        Additionally, once Section 4.9 is deleted pursuant to Paragraph 2 above,
        if ever, RS shall be relieved of and released and discharged from, any
        obligations it ever had under Section 4.6. Notwithstanding anything to
        the contrary set forth herein or in Section 2.3 of the MDA, MF

        to an affiliate of the Purchaser who agrees to be bound by this Section
        4(b), (ii) effected after any material breach by the Company of its
        obligations under Article 2, Article 3 or Section 10.2 of the Marketing

        ten (10) days written notice to Company, immediately divest the Shares
        if Company takes any action which is contrary to any of the obligations
        of Purchaser described in Section 4.9 of the Marketing Agreement
        (subject to compliance with the terms of this Agreement relating to any
        divestiture or sale of the Shares by Purchaser), regardless of whether

        -------------

        a.      This Amendment is supplementary to and modifies the MDA and SPA,
                as appropriate. The terms of this Amendment supersede provisions
                of the MDA and SPA only to the extent expressly provided herein.
                However, nothing contained in this Amendment should be
                interpreted as invalidating the MDA or SPA, and provisions of
                the MDA and SPA as modified by this Amendment will continue to
                govern relations between the Parties.

        b.      This Amendment shall inure to the benefit of and be binding upon

                may be executed by facsimile signature. All counterparts shall
                collectively constitute one and the same Amendment.

        d.      The terms and conditions contained in the MDA and SPA as
                modified by this Amendment constitute the entire agreement among
                the Parties relating to the subject matter hereof and shall
                supersede all previous agreements and communications between the
                Parties with respect to the subject matter of this Agreement. No
                Party has entered into this Amendment in reliance upon any
                representation, warranty, covenant or undertaking of any other
                Party that is not set out or referred to in this Amendment.
