     the previous month but no more than twenty-five percent
     (25%) of the amount budgeted to be incurred by the Company
     in the then-current Program for such prior month, unless

          (b)  TMS shall make its capital contribution to the
     Company, not later than the fifteenth (15th) day of the
     following calendar month, by delivering an invoice to the

     of any Program Costs not contributed by TMS through the
     provision of services for such month.

          (c)  Upon receipt of the capital contribution from MI,

       5.2.4  Failure to Make Capital Contribution. In the event
     that either TMS or MI fails to make a capital contribution
     pursuant to this Section 5.2 and in accordance with Section
     7.3 and the other Party does not elect to terminate the
     Program pursuant to Section 7.3.4 hereof, then, in addition
     to all other rights and remedies of the Members, the
     Percentage Interests in the Company shall be adjusted such
     that no distributions shall be made to the defaulting Member
     until all capital contributions have been contributed in
     full.

<PAGE>  17

       5.2.5  No Adjustment. Except as provided in Section
     5.2.4, none of the Program Capital Contributions paid under
     this Section 5.2 shall change the Percentage Interests of
     the Members.

       5.2.6  Right to Review.  MI and the Company have the
     right to review and evaluate the invoices submitted by TMS

     thereunder.

   5.3.  Additional Contributions. In the event that at the end
of each of the first four fiscal years of the Company, TMS does
not receive a distribution from Company Cash Flow equal to or
greater than its contribution of VSC Development Costs and
accounting service fee to the Company for that fiscal year (the
"TMS Distribution Deficiency"), MI agrees to contribute to the
Company the difference between: (i) the amount contributed by TMS
for VSC Development Costs and accounting service fee and (ii) the
Cash Flow distribution to TMS for such fiscal year ("Additional
Contribution"). At the time of making the Additional
Contribution, the Company shall make a payment to TMS equal to

    5.4.    Books of Account; Audit. TMS shall keep and maintain
proper and complete books of account, and shall maintain a bank
account, on behalf of the Company.  All books of account and bank
account shall be available and open to MI for review.  In the
event that either TMS or MI reasonably deems the Program to be
material to TMS or MI, as the case may be, for financial
accounting purposes, then, upon such Member's request, audited
financial statements of the Company shall be prepared by KPMG
Peat Marwick, LLP or other qualified certified public accounting
firm agreed upon by the Members.  Each Member shall keep and
maintain proper and complete records and books of account
documenting all Program Costs incurred by such Member. In the
event there has been discovered a Material Discrepancy, MI shall
have the right to require that an independent accounting firm
keep and maintain the books of account and bank account on behalf
of TMS in lieu of TMS and upon such request, TMS shall deliver
the records to the independent accountant and assist in the
transition.  Each of the Company, TMS and MI shall permit
independent accountants retained by TMS or MI (the "Auditing
Party") to have access to its records and books for the sole
purpose of determining the appropriateness of Program Costs
charged by or accrued to the Member being audited hereunder. Such
examination shall be conducted during regular business hours and
upon reasonable notice, at the Auditing Party's own expense and
no more than once in each calendar year during the term of this
Agreement and during the seven (7) calendar years following the
expiration or termination hereof, provided, such limitation of no
more than once each calendar year shall not apply if a Material
Discrepancy has been discovered.  If such examination reveals
that such Program Costs have been misstated, any adjustment shall
be promptly refunded or paid, as appropriate. The Auditing Party
shall pay the fees and expenses of the accountant engaged to
perform the audit, unless such audit reveals a Material
Discrepancy, in which case the Member who received such
overpayment shall pay all reasonable costs and expenses incurred
by the Auditing Party in the course of making such determination,
including the fees and expenses of the accountant and reimburse
the overpayment. The Company, TMS and MI shall each keep their
books and records relating to this Agreement and the Program for
a minimum of seven (7) years. The right to review records in this
Section 5.3 is in addition to and not in lieu of 18-305 of the
Act; provided no Manager shall have the right to keep
confidential any information from the other Manager.

    5.5.    Enforceability of Section 5.2.  The agreements
regarding Program Capital Contributions set forth in Sections 5.1
and 5.2 hereof are by and between, and for the benefit of, MI and
TMS only, and are not enforceable by any Third Party.

    5.6.    Further Funding.  In the event that the Members
determine at any time (or from time to time) that additional
funds in excess of the Program Costs and the initial capital
contributions are required by the Company for or in respect of
its business or to pay any of its obligations, expenses, costs,
liabilities, or expenditures (including, without limitation, any
operating deficits), then the Members may agree by unanimous
action to make additional contributions to the capital of the
Company or may, acting in their capacities as Managers, borrow
all or part of such additional funds on behalf of the Company,
with interest payable at then-prevailing rates, from one or more
of the Members or from commercial banks, savings and loan
associations, or other commercial lending institutions.

    5.7.    No Interest on Capital Contributions.  No interest
shall be paid on any contribution to the capital of the Company.

    5.8.    Capital Accounts.  A separate Capital Account shall
be established for each Member. Each Member's Capital Account
shall be subject to such adjustments as may be required in order
to comply with the capital account maintenance requirements of
Section 704(b) of the IRC.

                           ARTICLE VI
                 DISTRIBUTIONS AND ALLOCATIONS

     6.1. Allocations of Profit or Loss. After giving effect to
the special allocations set forth in this Section 6.2 and in
Section 6.3, for any Fiscal Year of the Company, Profit or Loss
shall be allocated to the Members in proportion to their
Membership Interests until all Additional Contributions are
recouped as provided in Section 6.2.2, in which case the Profit
or Loss shall thereafter be allocated to the Members in
proportion to their Percentage Interests

    6.3.    Regulatory Allocations.

       6.3.1. Qualified Income Offset.  If any Member unexpected
     ly receives an adjustment, allocation, or distribution as de
     scribed in Treasury Regulations Section
     1.704-1(b)(2)(ii)(d)(4) through (6) which causes or increas
     es a deficit capital account balance in such Member's Capi
     tal Account (as determined in accordance with such Regula
     tions) items of Company income and gain shall be specially
     allocated to each such Member in an amount and manner suffi
     cient to eliminate, to the extent required by the Treasury
     Regulations, the Adjusted Capital Account Deficit of such
     Member as quickly as possible, provided that an allocation
     pursuant to this Section 6.3.1 shall be made if and only to
     the extent that such Member would have an Adjusted Capital
     Account Deficit after all other allocations provided for in
     this Article VI have been tentatively made as if this Sec
     tion 6.3.1 were not in the Agreement. This provision is in
     tended to be a "qualified income offset," as defined in
     Treasury Regulations Section 1.704-1(b)(2)(ii)(d), such Reg
     ulations being specifically incorporated herein by refer
     ence.

       6.3.2.Minimum Gain Chargeback.  If there is a net de
     crease in Minimum Gain during any Fiscal Year, each Member
     shall be specially allocated items of Minimum Gain income
     and gain for such year (and, if necessary, subsequent years)
     in an amount equal to such Member's share of the net
     decrease in Minimum Gain, determined in accordance with
     Treasury Regulations Section 1.704-2(g). Allocations pursu
     ant to the previous sentence shall be made in proportion to
     the respective amounts required to be allocated to each Mem
     ber pursuant thereto. The items to be so allocated shall be
     determined in accordance with Treasury Regulations Sections
     1.704-2(f) and 1.704-2(j)(2). This Section 6.3.2 is intended
     to comply with the minimum gain chargeback requirement in
     Treasury Regulations Section 1.704-2(f) and shall be inter
     preted consistently therewith.

       6.3.3.Contributed Property and Book-ups.  In accordance
     with IRC Section 704(c) and the Regulations thereunder, as
     well as Regulation Section 1.704-1(b)(2)(iv)(d)(3), income,
     gain, loss, and deduction with respect to any property
     contributed (or deemed contributed) to the Company shall,
     solely for tax purposes, be allocated among the Members so
     as to take account of any variation between the adjusted
     basis of the property to the Company for federal income tax
     purposes and its fair market value at the date of
     contribution (or deemed contribution). If the adjusted book
     value of any Company asset is adjusted as provided herein,
     subsequent allocations of income, gain, loss, and deduction
     with respect to the asset shall take account of any
     variation between the adjusted basis of the asset for
     federal income tax purposes and its adjusted book value in
     the manner required under IRC Section 704(c) and the
     Regulations thereunder.

    6.4.    Liquidation and Dissolution.

       6.4.1.Distribution of Assets. If the Company is
     liquidated, the assets of the Company shall be distributed
     to the Members in accordance with the positive balances in
     their respective Capital Accounts, after taking into account
     the allocations of Profit or Loss pursuant to Section 6.2,
     if any, and distributions, if any, of cash or property,
     pursuant to Section 6.1.  Notwithstanding anything herein to
     the contrary, certain assets of the Company shall be
     distributed under, and the Members shall have certain rights
     pursuant to, Section 10.5 of this Agreement.

       6.4.2.No Capital Account Deficit Restoration. No Member
     shall be obligated to restore a deficit Capital Account.

[*CONFIDENTIAL TREATMENT REQUESTED]

    6.5.    General.

       6.5.1.Timing of Distributions. Except as otherwise
     provided in this Agreement, the timing and amount of all
     distributions shall be determined by the unanimous vote of
     the Members.

       6.5.2.Distributions in Kind. If any assets of the Company
     are distributed in kind to the Members, those assets shall
     be valued on the basis of their fair market value, and any
     Member entitled to any interest in those assets shall
     receive that interest as a tenant-in-common with all other
     Members so entitled. Unless the Members otherwise agree, the
     fair market value of the assets shall be determined by an
     independent appraiser who shall be selected by the Members.
     The Profit or Loss for each unsold asset shall be determined
     as if the asset had been sold at its fair market value, and
     the Profit or Loss shall be allocated as provided in Section
     6.2 and shall be properly credited or charged to the Capital
     Accounts of the Members prior to the distribution of the
     assets in liquidation pursuant to Section 6.4.

       6.5.3.Allocations of Profit and Loss. All Profit and Loss
     shall be allocated, and all distributions shall be made, to
     the Persons shown on the records of the Company to have been
     Members as of the last day of the taxable year for which the
     allocation or distribution is to be made. Notwithstanding
     the foregoing, unless the Company's taxable year is
     separated into segments, if there is a Transfer or an Invol
     untary Withdrawal during the taxable year, the Profit or
     Loss shall be allocated between the original Member and the
     successor on the basis of the number of days each was a
     Member during the taxable year; PROVIDED, HOWEVER, the
     Company's taxable year shall be segregated into two or more
     segments in order to account for Profit, Loss, or proceeds
     attributable to any extraordinary nonrecurring items of the
     Company.

       6.5.4.Compliance Amendments. The Members are hereby
     authorized, upon the advice of the Company's tax counsel, to
     amend this Article VI to comply with the IRC and the
     Regulations promulgated under IRC Section 704(b); PROVIDED,
     HOWEVER, that no amendment shall materially affect distribu
     tions to a Member without the Member's prior written
     consent.

   6.6  Capital Transactions.  Company Cash Flow attributable to a
Capital Transaction shall be distributed to the Members in
proportion to their Percentage Interests.

     of the licenses granted and assignments made by TMS in this
     Agreement, the Company hereby undertakes to pay all
     royalties, sublicense fees and other costs or expenses

     Products, all in accordance with the Program.  TMS shall
     not, however, be required to undertake activities in
     furtherance of the Program in the absence of funding from
     the Company pursuant to the provisions of this Agreement. As
     used in this Agreement, the phrase "commercially reasonable,
     diligent and consistent efforts" will mean that level of
     effort which, consistent with the exercise of prudent
     technical and business judgment, is applied by TMS to its
     other software products at a similar stage of development
     and with similar commercial potential or by other companies
     to their software in a similar stage of development and with

     Date and ending on December 31, 2003. The Program shall be
     updated annually by the Members not later than sixty (60)
     days prior to January 1 of each year during the Program.
     Each such updated Program shall include a detailed
     description and budget for the development activities
     proposed for the forthcoming calendar year. TMS shall be
     primarily responsible for preparing the annual updates to
     the Program and, in connection with the preparation of such
     updates, shall consult with MI regarding the identification,
     timing and execution of and budget for the major tasks and
     detailed activities required to perform the updated Program.
     Each such updated Program shall be signed by an authorized
     representative of each of TMS and MI, and MI and TMS shall
     each designate their respective members who will work on the
     Program (the "Program Management Team").  The members of the
     Program Management Team shall actively consult with one
     another throughout the term of the Program so as to adjust
     the specific work performed under the Program to conform to
     evolving developments in technology and the results of the
     development work performed. While minor adjustments to the
     Program may be made from time to time upon approval of the
     members of the Program Management Team, significant changes
     in the scope or direction of the work and any changes in
     funding exceeding twenty-five percent (25%) of the total
     amount budgeted in any calendar year for the Program must be
     approved by all Members, in the absence of which approval
     the most recently approved Program shall remain in effect.

       7.3.4.Breach/Termination or Assumption of the Program.
     In addition to all remedies available at law, under the Act
     or under this Agreement, in the event that either Member is
     in breach of their Program duties as specified hereunder
     (including, but not limited to, the obligation under Section
     5.2 and 7.3 of this Agreement) or fails to adequately or
     consistently perform such duties, then the non-defaulting
     Member shall have the right, upon thirty (30) days' prior
     written notice, at its election, if the default has not been
     remedied by the defaulting Member, to either terminate the
     Program or assume the responsibilities of the defaulting
     Member, in which event the last sentence of Section 7.3.5
     shall apply. Termination of the Program shall not affect the
     rights granted to the Members under the License Agreements
     or the Escrow Agreement.

       7.3.5.Transfer, Withdrawal or Failure to Perform by TMS.
     In the event there is a Transfer or Encumbrance by TMS of
     its Membership Interest or a withdrawal by TMS as a Member
     of the Company or a Buy-Sell Event with regard to TMS, then
     MI shall have the right to perform the VSC Development
     Services and develop the Program and assume all the rights
     and obligations of TMS under this Article VII and Section
     5.2.  In such event, TMS shall assist in the transition and
     assign all rights to development work performed under the
     Program and to VSC Products to the Company and MI.  MI and
     the Company shall be entitled to reverse assemble and
     decompile the VSC Technology and VSC Products and shall be
     entitled to modify the VSC Technology and VSC Products and
     to make derivative work therefrom.

       7.3.6.Delivery of VSC Technology Package.  TMS shall
     deliver the VSC Technology Package with regard to the
     Program to each of the Company and MI on a mutually-
     agreeable time upon each new version Release of the VSC
     Technology and at such other time as it may be requested by
     MI or the Company.

    7.4.    Assistance by MI.  It is understood and agreed that
TMS has the ability to perform the services for which it is being
paid the VSC Development Costs, but needs certain assistance from
MI to perfect same.  If TMS requests the assistance of MI for the
development and maintenance of the VSC Technology, and the cost
thereof is not covered by the then current Program Budget, the
Company shall reimburse MI for employee travel and other expense
costs and, in the event of active programming by MI which would
result in the modification of the computer code, all direct and
indirect costs relating thereto consistent with the provisions
set forth in Section 5.2.2 of this Agreement and Section 6 of
Schedule II-A to this Agreement.

    7.5.    Intellectual Property Ownership.

     and other Technology, whether or not patentable or
     copyrightable, and any patent applications, patents or
     copyrights based thereon, that are discovered, made or
     conceived during and in connection with the Program solely
     by employees of either Member or others acting on behalf of
     such Member, or jointly by employees of both Members, shall
     be assigned to and owned by the Company. Each of TMS and MI
     shall promptly disclose to the Company and the other Member
     the making, conception or reduction to practice of Program
     Inventions by employees or others acting on behalf of such
     Member.

       7.5.2.    Ownership of Trademarks.  The Company shall own
     all Product Marks and all goodwill therein shall inure to
     the benefit of the Company, and all expenses incurred by a
     Member with respect thereto shall be considered Program
     Costs. All Product Marks shall be registered in the name
     of the Company if and when registered.

<PAGE>  26

       7.5.3.Cooperation of Employees.  Each of TMS and MI
     represents and agrees that all employees or Persons acting
     on its behalf in performing its obligations under this
     Agreement shall be obligated under a binding written
     agreement to assign to such Member, or as such Member shall
     direct, all Program Inventions made or conceived by such
     employee or other person in performance of such Member's
     obligations under this Agreement. In the case of
     non-employees working for other companies or institutions on
     behalf of TMS or MI, TMS or MI, as applicable, shall have
     the right to obtain assignments and/or licenses for all
     Program Inventions made by such non-employees on behalf of
     TMS or MI, as applicable, in accordance with the policies of
     said company or institution.  TMS and MI agree to undertake
     to enforce such agreements (including, where appropriate, by
     legal action) considering, among other things, the
     commercial value of such Inventions.

    7.6.    Filing, Prosecution and Maintenance of Patent
Rights.

       7.6.1.Filing, Prosecution and Maintenance.  TMS, on
     behalf of the Company, shall be responsible for the filing,
     prosecution and maintenance of all Program Patent Rights.
     TMS shall provide MI with copies of same and MI shall have
     the right to provide input and review and to approve all
     such matters.  If, however, with respect to any particular
     Invention or the filing, prosecution or maintenance of any
     particular patent application with respect thereto, TMS has
     neglected to file, prosecute or maintain the same, then MI
     shall have the right to assume the responsibility for
     filing, prosecuting and maintaining the same. MI shall be
     equally entitled with TMS to all attorney/client, patent
     office and other communications relating to the Program
     Patent Rights and MI shall be given a power to inspect all
     Program Patent Rights, including a power to inspect all
     pending patent applications in the United States Patent
     Office and any other offices that otherwise would hold such
     applications in secrecy.

       7.6.2.Patent Filing Costs.  All costs associated with
     filing, prosecuting and maintaining patent applications and
     patents covering the Program Patent Rights shall be deemed
     VSC Direct Development Costs.  For purposes of this Section
     7.6, "prosecution and maintenance" of Patent Rights shall be
     deemed to include, without limitation, the conduct of
     interferences or oppositions, and/or requests for
     re-examinations, reissues or extensions of patent terms. If,
     pursuant to Section 7.6.1 above, MI assumes the
     responsibility of filing, prosecuting and maintaining a
     patent application, all costs and fees associated with such
     filings made by MI shall be considered to be a VSC Direct
     Development Cost to the Company.

<PAGE>  27

    7.7.    Cooperation.  MI and TMS shall each make its
personnel available to to the other Member (or the other Member's
authorized attorneys, agents or representatives) to the extent
necessary or appropriate to enable TMS or MI, as the case may be
to file, prosecute and maintain patent applications and resulting
patents with respect to Program Technology and for periods of
time sufficient for TMS or MI, as the case may be, to obtain the
assistance it needs from such personnel. Where appropriate, MI,
or TMS, as the case may be, shall sign or cause to have signed
all truthful documents relating to said patent applications or
patents at no charge to such Member for the other Member's
execution of same.

    7.8.    No Other Technology Rights.  Except as otherwise
expressly provided in this Agreement, under no circumstances
shall a Member hereto, as a result of this Agreement, obtain any
ownership interest in or other right to the Patent Rights or
Technology of the other Member, including items owned, Controlled
or developed by the other Member, or transferred by the other
Member to said Member at any time pursuant to this Agreement.  It
is understood and agreed that this Agreement does not grant
either Member, or the Company, any license or other right in the
Patent Rights of the other Member except as expressly provided in
Article 5 hereof and this Article 7.

     7.11 Enforcement of Patent Rights.

       7.11.1.Enforcement. Subject to the provisions of this
     Section 7.11, in the event that TMS or MI reasonably
     believes that any Program Patent Rights or Program
     Technology necessary for the use or sale of VSC Products or
     VSC Services is infringed or misappropriated by a Third
     Party or is subject to a declaratory judgment action arising
     from such infringement in a country, in each case with
     respect to the manufacture, sale or use of a product
     potentially competitive with a VSC Product or VSC Service
     within the Field, MI or TMS (respectively) shall promptly
     notify the other Member hereto. Promptly after such notice
     the Members shall meet to discuss the course of action to be
     taken with respect to an Enforcement Action (as defined
     below) with respect to such infringement or
     misappropriation, including the control thereof and sharing
     of costs and expenses related thereto, for the purposes of
     entering into a litigation agreement setting forth the same
     ("Litigation Agreement"). If the Parties do not enter such
     Litigation Agreement, TMS shall have the initial right (but
     not the obligation) to enforce the intellectual property
     rights within such Patent Rights or Technology, or defend
     any declaratory judgment action with respect thereto (for
     purposes of this Section 7.11, an "Enforcement Action");
     provided that TMS agrees to indemnify MI for any and all
     liabilities and expenses (including, without limitation,
     reasonable attorneys' fees and other expenses of litigation)
     incurred by MI as a result of such Enforcement Action. If
     TMS does not elect to commence the Enforcement Action, and
     MI does so, then MI shall agree to indemnify TMS for the
     foregoing liabilities and expenses.

       7.11.2.Information.  Absent a Litigation Agreement, the
     Member initiating or defending any such Enforcement Action
     shall keep the other Member hereto reasonably informed of
     the progress of any such Enforcement Action, and such other
     Member shall have the right to participate with counsel of
     its own choice at its own expense.

       7.11.3.Enforcement Costs; Recoveries. Unless otherwise
     agreed under Section 7.11.1, the Member initiating an
     Enforcement Action shall, at the option of such Member, have
     the right to either: (i) assume responsibility for all costs
     and expenses of such Enforcement Action, in which case all
     amounts recovered in the Enforcement Action (including
     without limitation amounts resulting from a settlement
     thereof) shall be retained by such Member; or (ii) include
     such costs and expenses within the Administrative Costs of
     the Company, in which case all amounts recovered in the
     Enforcement Action, after reimbursing the Member initiating
     the Action for any costs and expenses not previously so
     offset, shall be shared by TMS and MI in accordance with
     their respective Membership Interests.

<PAGE>  30

     7.12.     Third Party Rights.  The foregoing provisions of
this Article 7 shall be subject to and limited by any agreements
pursuant to which TMS and MI, as the case may be, acquired any
particular Patent Rights or Technology.

     7.13.     Third Party Agreements; Reports.  To the extent
that a Member is obligated to provide reports to a Third Party
pursuant to a Third Party Agreement as a result of or reporting
on the status of activities of the other Member hereunder, the
other Member hereto shall reasonably assist the reporting Member
by providing information in its possession or control and in
sufficient detail to complete and submit such reports as
required. Any information to be included in such reports shall be
subject to the provisions of the Master Agreement relating to
confidentiality.

                          ARTICLE VIII
          TRANSFER OF INTERESTS - VOLUNTARY TRANSFERS

     8.1.    Restrictions on Transfer.  No Member, voluntarily or
involuntarily, may Transfer, or create or suffer to exist any
Encumbrance against, any Membership Interest, except as expressly
allowed either in this Article VIII or in Article IX.
Notwithstanding any other provision of this Agreement, any
purported Transfer or Encumbrance of any Membership Interest in
violation of this Agreement shall be void, and shall not transfer
any interest or title to the purported transferee. The Company
shall not be required to transfer on its books any Membership
Interest Transferred or Encumbered in violation of this
Agreement, or to treat the transferee as owner of the Membership
Interest in any manner.

<PAGE>  31

     8.2.    Third-party Transfers by Members.  A Member may
Transfer all or part of its Membership Interest to a third-party
in accordance with the provisions of this Section 8.2.

       8.2.1.    Transfer Request.  If a Member intends to
     transfer all or part of its Membership Interest (the
     "Offered Interest") to any Person, the Member (the
     "Transferor") first shall submit to the Company a written
     request to transfer the Offered Interest (the "Transfer
     Request").  The Transfer Request shall name specifically the
     Person to whom the Transferor intends to transfer the
     Offered Interest (the "Proposed Transferee") and the price
     and other terms upon which the intended transfer is to be
     made, and shall include copies of the written offer and
     pertinent documentation.

       8.2.2.    Approval of Request.  If all of the
     Disinterested Members approve the proposed Transfer in
     writing within thirty (30) days after receipt by the Company
     of the Transfer Request, then, for a period of thirty (30)
     days thereafter, the Transferor may Transfer its economic
     rights in the Offered Interest to the Proposed Transferee,
     on the terms specified in the Transfer Request; provided,
     however, TMS' rights to transfer its economic interest shall
     be subject to MI's rights under Section 7.3.5.  If the
     Transferor does not Transfer its economic rights in the
     Offered Interest to the Proposed Transferee on the terms
     specified in the Transfer Request within such thirty (30)
     day period, the Offered Interest again shall be subject to
     all of the restrictions on Transfer and other terms of this
     Agreement. The transferee of an Offered Interest (i) shall
     have only those rights specified in Section 8.3 (subject to
     Section 7.3.5), (ii) shall be admitted as a Member only upon
     full compliance with Section 8.2.6; and (iii) shall be
     subject to all the restrictions on transfer imposed under
     this Operating Agreement.  The decision by a Disinterested
     Member whether to approve a proposed Transfer of an Offered
     Interest shall be in such Member's sole and absolute
     discretion.

       8.2.3.    Denial of Request / Right of First Refusal.  If
     the Disinterested Members do not approve unanimously the
     proposed Transfer as set forth in Section 8.2.2 within
     thirty (30) days after receipt by the Company of the
     Transfer Request, then the Transfer Request shall be deemed
     an offer to sell the Offered Interest to the Company at the
     lower of (i) the price offered by the Proposed Transferee or
     (ii) the price as determined under Section 8.5, each upon
     the other terms offered by the Proposed Transferee (the
     "Transfer Offer").  The Company may accept the Transfer
     Offer with respect to part or all of the Offered Interest by
     resolutions approved by a Majority in Interest of the
     Disinterested Members, delivered to the Transferor and all
     other Members within forty-five (45) days following receipt
     by the Company of the Transfer Request.  If the Company does
     not accept the Transfer Offer, each of the Members, except
     the Transferor, may accept the Transfer Offer by giving
     written notice thereof to the Transferor and all other
     Members within sixty (60) days following receipt by the
     Company of the Transfer Request.  The Transfer Offer will be
     allocated among the Members who accept it (the "Accepting
     Members") in the proportion they mutually agree upon, or, in
     the absence of agreement, in the ratio that each of the
     Accepting Members' Percentage Interest, at the time of the
     Company's receipt of the Transfer Request, bears to the
     aggregate Percentage Interests, at the time of the Company's
     receipt of the Transfer Request, of all the Accepting
     Members.  The parties that accept the Transfer Offer, if
     any, whether the Company or Members, shall be referred to
     hereinafter individually and collectively as the
     "Transferee."  Notwithstanding anything herein to the
     contrary, the Transferor shall not be obligated to sell any
     part of the Offered Interest to the Company or the Accepting
     Members unless all of the Offered Interest is purchased
     either by the Company, one or more other Members or a
     combination of any of them.  If the Transfer Offer is not
     accepted with respect to the entire Offered Interest by the
     Company and/or other Members within sixty (60) days
     following receipt by the Company of the Transfer Request,
     then the Transfer shall be deemed to have been approved, and
     the provisions of Section 8.2.2 shall be applicable to the
     Transfer.

<PAGE>  32

       8.2.4.    Closing.  The closing of the purchase of an
     Offered Interest pursuant to this Section 8.2 shall take
     place on a date agreed upon by the Transferor and the
     Transferee, but not later than ninety (90) days after the
     later of receipt by the Company of the Transfer Request or
     determination of the purchase price under Section 9.5, as
     the case may be.  Upon payment of the purchase price, the
     Transferor shall execute and deliver such assignments and
     other instruments as are reasonably necessary to evidence
     and carry out the transfer of the Offered Interest to the
     Transferee, including a certificate dated as of the date of
     closing containing a representation and warranty that the
     Transferor has transferred to the Transferee good and
     marketable title to the Offered Interest free and clear of
     all Encumbrances.  In connection with the sale of an Offered
     Interest pursuant to this Section 8.2, unless otherwise
     agreed by the Transferee and the Transferor, the Transferee
     will assume the Transferor's allocable portion of Company
     obligations, to the extent related to the Offered Interest,
     as well as the Transferor's individual obligations, to the
     extent related to the Offered Interest, other than income
     tax liabilities of the Transferor.

       8.2.5.    Non-cash Consideration.  If any consideration
     to be received by the Transferor for the Offered Interest is
     property other than cash, then the price shall be measured
     to that extent by the fair market value of such non-cash con
     sideration.  Fair market value for purposes of this Section
     8.2.5 shall mean the sum of (i) the fair market value of any
     non-cash consideration offered for the Offered Interest,
     plus (ii) the value of any special benefits to the
     Transferor of such non-cash consideration to the extent they
     reasonably can be identified and valued, plus (iii) the
     amount of any additional expense or cost, including
     additional taxes, incurred by the Transferor in accepting
     cash instead of such non-cash consideration, in each case
     based upon a realistic appraisal of such non-cash
     consideration, special benefits, expense or cost agreed upon
     by the Transferor and the Transferee.  If the Transferor and
     the Transferee are unable to agree, then they shall select
     an independent qualified appraiser, whose determination
     shall be final and conclusive, and the cost of the appraiser
     shall be divided equally between the Transferor and the
     Transferee.  If the Transferor and the Transferee are unable
     to agree on a single appraiser, then the Transferor shall
     select and pay for an independent qualified appraiser, and
     the Transferee shall select and pay for an independent
     qualified appraiser. If the two appraisers agree, then their
     determination shall be final and conclusive. If the two
     appraisers are unable to agree, then they shall select a
     third appraiser, and the determination of two of the three
     appraisers shall be final and conclusive. The cost of the
     third appraiser shall be divided equally between the
     Transferor and the Transferee.

       8.2.6. Additional Requirements for Valid Transfer.  No
     purported Transfer otherwise complying with this Section 8.2
     will be effective until the Transferor and the Transferee
     furnish to the Company such instruments and assurances as
     the Members request, including, if requested, an opinion of
     counsel satisfactory to the Company that the interest in the
     Company being Transferred has been registered or is exempt
     from registration under the Securities Act of 1933, as
     amended (the "Securities Act"), and applicable state
     securities laws. No Transfer will be effective if it would
     result in the "termination" of the Company under 708 of the
     IRC unless the Members give their prior written consent to
     the Transfer. The approval required under this Section 8.2.6
     will be the unanimous approval of the Disinterested Members.
     No Transferee shall be admitted as a Member of the Company
     unless the Disinterested Members give their prior written
     consent.

<PAGE>  33

       8.2.7.    Effect on Transferor's Interest.  From the date
     of the receipt by the Company of the Transfer Request to the
     date of the Transfer of the Offered Interest pursuant to
     this Article VIII, (i) the Percentage Interest represented
     by the Transferor's Membership Interest will be excluded
     from any calculation of aggregate Percentage Interests for
     purposes of any approval required of Members under this
     Agreement; and (ii) the Transferor shall take no action in
     its capacity as Manager and the other Member shall act as
     the sole Manager.

     8.3.    Rights of Transferee.  Unless admitted as a Member
of the Company in accordance with Section 8.2.6, the transferee
of a Membership Interest or a part thereof shall not be entitled
to any of the rights, powers or privileges of its predecessor in
interest, except that such transferee shall be entitled to
receive and be credited or debited with its proportionate share
of the Company's Distributions and tax allocations.

     8.4.    Rights Remain with Company.  In the event of a
Transfer by a Member, (i) the obligations of the Company under
the LLC DMR License Agreement, the MI VSC License Agreement, the
TMS VSC License Agreement and the Escrow Agreement shall remain
in full force and effect, (ii) all licenses and grants made by
the Transferring Member to the Company shall remain in full force
and effect, and (iii) prior to such Transfer, the Transferring
Member shall have complied in full with its obligations under
Section 7.5. In the event of a Transfer by TMS, MI shall have the
right to perform the TMS obligations under Article VII in
accordance with the terms of Section 5.2.

                    INVOLUNTARY TRANSFERS

     9.2.    Buy-Sell Notice.  Upon the occurrence of a Buy-Sell
Event, the Member to whom such event has occurred (the "Withdraw
ing Member"), shall give notice of the Buy-Sell Event (the "Buy-
Sell Notice") to the Members within ten (10) days after its
occurrence.  If the Withdrawing Member fails to give the Buy-Sell
Notice, any Member may give the notice at any time thereafter,
and by so doing commence the buy-sell procedure provided for in
this Article IX.  The date on which the Buy-Sell Notice is
delivered to the Company shall be referred to herein as the
"Notice Date."  The Withdrawing Member's Membership Interest, in
whole and in part, shall be referred to herein as the
"Withdrawing Interest."  For purposes of this Article IX, a
Withdrawing Member shall also mean the owner of a Withdrawing
Interest.

     9.3.    Purchase Option.  Upon the occurrence of a Buy-Sell
Event, the Company shall have an option to purchase the
Withdrawing Interest on the terms and conditions set forth in
this Article IX (the "Purchase Option").  The Company may elect
to exercise the Purchase Option by resolutions approved by a
Majority in Interest of the Disinterested Members, delivered to
the Withdrawing Member and all Members within thirty (30) days
after the Notice Date.  If the Company does not elect to exercise
the Purchase Option, each of the Members, except the Withdrawing
Member and any other Withdrawing Member, may exercise the
Purchase Option.  The Purchase Option will be allocated among the
Members who elect to purchase (the "Purchasing Members") in the
proportion they mutually agree upon, or, in the absence of
agreement, in the ratio that each of the Purchasing Members'
Percentage Interest, at the time of the Buy-Sell Event, bears to
the aggregate Percentage Interests of all Purchasing Members, at
the time of the Buy-Sell Event.  The Purchasing Members must give
notice of their election to exercise the Purchase Option to the
Withdrawing Member and all other Members within forty-five
(45) days after the Notice Date.  The party or parties that
exercise the Purchase Option, if any, whether the Company or
Members or a Purchase Option Assignee (as defined in Section
9.4), shall be referred to hereinafter individually and
collectively as the "Purchaser."

<PAGE>  35

     9.4.    Assignment of Purchase Option.  If, at the
occurrence of a Buy-Sell Event, there exist only two (2) then-
current Members, including the Withdrawing Member, the Member
that is not withdrawing shall have the option during the thirty
(30) day period after the Notice Date to assign its Purchase
Option to any Person other than the Withdrawing Member (the
"Purchase Option Assignee") by notifying the Withdrawing Member
and the Company of such assignment in writing.  After delivery of
such notice, the Purchase Option Assignee shall have the option
to purchase the Withdrawing Interest on the same terms and
conditions as would apply to the Member from which the Purchase
Option was assigned.  However, the Purchase Option Assignee shall
not have the right of assignment set forth in this Section 9.4.
In the event the Purchase Option Assignee does not exercise the
Purchase Option, the Purchase Option Assignee shall have no
further rights under this Agreement.

     9.5.    Agreement on Valuation.  Unless otherwise agreed in
writing by the Withdrawing Member and the Purchaser within sixty
(60) days after the Notice Date, the purchase price for the
Withdrawing Interest shall be the value of the Withdrawing
Interest as of the Buy-Sell Event, as determined by an
independent qualified appraiser agreed upon by the Withdrawing
Member and the Purchaser. The appraiser's determination shall be
final and conclusive, and the cost of the appraiser shall be
divided equally between the Withdrawing Member and the Purchaser.
If the Withdrawing Member and the Purchaser are unable to agree
on a single appraiser, then the Withdrawing Member shall select
and pay for an independent qualified appraiser, and the Purchaser
shall select and pay for an independent qualified appraiser.  If
the two appraisers agree, then their determination shall be final
and conclusive.  If the two appraisers are unable to agree, then
they shall select a third appraiser, and the determination of two
of the three appraisers shall be final and conclusive.  The cost
of the third appraiser shall be divided equally between the
Withdrawing Member and the Purchaser.

<PAGE>  36

     9.6.    Closing.  The closing (the "Closing") of the
purchase of a Withdrawing Interest pursuant to this Article IX
shall take place on a date agreed upon by the Withdrawing Member
and the Purchaser, but not later than ninety (90) days after the
later of the Notice Date or the date the purchase price is
determined by the appraisal process if the purchase price has not
been agreed upon.  The purchase price for the Withdrawing
Interest will be payable at Closing in the manner set forth in
Section 9.7.  Upon payment of the purchase price, the Withdrawing
Member shall execute and deliver such assignments and other
instruments as are reasonably necessary to evidence and carry out
the transfer of the Withdrawing Interest to the Purchaser,
including a certificate dated as of the date of Closing
containing a representation and warranty that the Withdrawing
Member has transferred to the Purchaser good and marketable title
to the Withdrawing Interest free and clear of all Encumbrances.
In connection with the sale of a Withdrawing Interest pursuant to
this Article IX, unless otherwise agreed by the Withdrawing
Member and the Purchaser, the Purchaser will assume the
Withdrawing Member's allocable portion of Company obligations, to
the extent related to the Withdrawing Interest, as well as the
Withdrawing Member's individual obligations, to the extent
related to the Withdrawing Interest, other than income tax
liabilities of the Withdrawing Member.

    9.7.    Payment of Purchase Price.  The purchase price for
the Withdrawing Interest shall be paid as follows:

       9.7.1.Purchase Price.  The purchase price for the
     Withdrawing Interest purchased pursuant to this Article IX
     shall be paid, at the option of the Purchaser, by cash or by
     the delivery of a promissory note (the "Note") and a cash
     down payment; provided, however, if the purchase price is
     $100,000 or less, the entire purchase price shall be paid in
     cash.  The cash down payment shall equal at least twenty
     percent (20%) of the purchase price.  The Note shall provide
     for equal quarterly installments of principal and accrued
     interest over a two (2) year term.  The term shall begin on
     the Closing, and the Note shall bear interest at the minimum
     applicable rate allowed at the time under the imputed
     interest rules of the IRC.  The Note may be prepaid in whole
     or in part at any time without penalty.

       9.7.2.Security Interest.  If part of the purchase price
     is paid by delivery of the Note, then, as security for
     payments due under the terms of the Note, the Purchaser
     shall grant to the Withdrawing Member a security interest in
     the Withdrawing Interest by executing a pledge and escrow
     agreement and whatever additional documents may be necessary
     to perfect the security interest of the Withdrawing Member.
     The security documents shall provide that the Purchaser
     shall deposit the Withdrawing Interest with an escrow agent
     and that if the Purchaser defaults under the terms of the
     Note or the security documents, the Withdrawing Member shall
     have the right to receive possession of the Withdrawing
     Interest and to exercise all other rights of a secured party
     under the North Carolina Uniform Commercial Code.

    9.8.    Effect on Withdrawing Member's Interest.  From the
date of the occurrence of the Buy-Sell Event and thereafter, (i)
the Withdrawing Member shall have only the rights of a transferee
of a Membership Interest set forth in Section 8.3; (ii) the
Withdrawing Member shall not be considered a Member for any
purpose under this Agreement; (iii) the Percentage Interest
represented by the Withdrawing Interest, if any, will be excluded
from any calculation of aggregate Percentage Interests for
purposes of any approval required of Members under this
Agreement; (iv) the Withdrawing Member shall take no action in
its capacity as Manager; and (v) if the Withdrawing Member is
TMS, Section 7.3.5 shall apply.  If the Withdrawing Interest is
purchased pursuant to the Purchase Option, after Closing, the
Purchaser, if not the Purchasing Member, shall have only those
rights specified in Section 8.3 with respect to the Withdrawing
Interest, and shall be admitted as a Member with respect to the
Withdrawing Interest only upon full compliance with Section
8.2.6.

    9.9.    Failure to Exercise Purchase Option.  Notwith
standing anything to the contrary in this Agreement, the
Withdrawing Member shall not be obligated to sell the Withdrawing
Interest pursuant to this Article IX unless the Company, the
Members or a combination of any of them exercise the Purchase
Option with respect to the entire Withdrawing Interest.  If the
Purchase Option is not exercised with respect to the entire
Withdrawing Interest by the Company and/or Members within forty-
five (45) days after the Notice Date, then, by giving written
notice to the Company and all of the Members within sixty (60)
days after the Notice Date, the Withdrawing Member may decline to
sell the Withdrawing Interest to the Purchaser.  In such event,
the Purchase Option shall be deemed terminated with respect to
the Buy-Sell Event that triggered the Purchase Option.  However,
the Withdrawing Interest shall continue to be subject to all of
the restrictions on Transfer and other terms of this Agreement,
except with respect to the Buy-Sell Event that triggered the
terminated Purchase Option, and the Person owning the Withdrawing
Interest shall have only those rights specified in Section 8.3
with respect to the Withdrawing Interest, and shall be admitted
(or re-admitted) as a Member with respect to the Withdrawing
Interest only upon full compliance with Section 8.2.6.

    9.10.       18-304 of the Act.  Nothing in this Article IX
shall effect the provisions of 18-304 of the Act, which shall
remain in full force and effect notwithstanding the exercise or
failure to exercise a Purchase Option.

<PAGE>  38

    9.11.      Rights Remain with Company.  In the event of a
Buy-Sell Event by a Member or a Member ceases to be a Member
pursuant to  18-304 of the Act, (i) the obligations or rights of
the Company and Members under the MI VSC License Agreement, the
TMS VSC License Agreement, the LLC DMR License Agreement and the
Escrow Agreement shall remain in full force and effect, and (ii)
all licenses and grants made by the Withdrawing Member to the
Company shall remain in full force and effect.  In the event of a
Buy-Sell Event by TMS, the terms of Section 7.3.5 shall apply.

                           ARTICLE X
           DISSOLUTION AND LIQUIDATION OF THE COMPANY

    10.1.      Dissolution Events.  The Company will be
dissolved upon the happening of any of the following events:

       (a) All or substantially all of the assets of the Company
    are sold, exchanged, or otherwise transferred (unless the
    Members have elected to continue the business of the
    Company);

       (b) All Members sign a document stating their election to
    dissolve the Company;

       (c) The entry of a final judgment, order, or decree of a
    court of competent jurisdiction adjudicating the Company to
    be bankrupt and the expiration without appeal of the period,
    if any, allowed by applicable law in which to appeal;

       (d) The expiration of the term of the Company (as set
    forth in Section 1.6); or

       (e) The entry of a decree of judicial dissolution or the
    issuance of a certificate for administrative dissolution
    under the Act.

    10.2.      Continuation.  Upon the occurrence of any of the
events described in Section 10.1(e) above with respect to any of
the Members, the business of the Company will be continued if
within ninety (90) calendar days a Majority in Interest of the
remaining Members elect to continue the business of the Company.
If the Members fail to continue the Company's business as
provided in this Section, the Company will be liquidated under
Section 10.3.

    10.3.      Liquidation.  Upon the happening of any of the
events specified in Section 10.1 and, if applicable, the failure
to continue the business of the Company under Section 10.2, the
Members, or any liquidating trustee elected by a Majority in
Interest of the Members, will commence as promptly as practicable
to wind up the Company's affairs unless the Members or the
liquidating trustee (either, the "Liquidator") determines that an
immediate liquidation of Company assets would cause undue loss to
the Company, in which event the liquidation may be deferred for a
time determined by the Liquidator to be appropriate. Assets of
the Company may be liquidated or distributed in kind, as the
Liquidator determines to be appropriate. The Members will
continue to share Company Cash Flow, Profits, and Losses during
the period of liquidation in the manner set forth in Article VI.
The proceeds from liquidation of the Company, including repayment
of any debts of Members to the Company, and any Company assets
that are not sold in connection with the liquidation will be
applied in the following order of priority:

       (a) To payment of the debts and satisfaction of the other
    obligations of the Company, including without limitation
    debts and obligations to Members;

       (b) To the establishment of any reserves deemed appropri
    ate by the Liquidator for any liabilities or obligations of
    the Company, which reserves will be held for the purpose of
    paying liabilities or obligations and, at the expiration of
    a period the Liquidator deems appropriate, will be distribut
    ed in the manner provided in Section 10.3(c); and

       (c) To the payment to the Members of the positive bal
    ances in their respective capital accounts, pro rata, in
    proportion to the positive balances in those capital
    accounts after giving effect to all allocations and distri
    butions under Article VI for all prior periods, including
    the period during which the process of liquidation occurs.

    10.4.      Articles of Dissolution.  Upon the dissolution
and commencement of the winding up of the Company, the Members
shall cause Articles of Dissolution to be executed on behalf of
the Company and filed with the Secretary of State, and the
Members shall execute, acknowledge, and file any and all other
instruments necessary or appropriate to reflect the dissolution
of the Company.

Program Technology and all Company Patent Rights, subject to the
rights of MI under the MI DMR License Agreement and the MI VSC
License Agreement and TMS under the TMS VSC License Agreement,
with no obligation to account to or pay royalties or other funds
to the other Member or to account to or pay the other Member for
future exploitation or use of the VSC Technology and any
derivative works, (ii) each Member shall grant to the other
Member a perpetual, paid-up, non-exclusive license to whatever
licenses are necessary to implement the VSC Technology,
including, but not limited to, those licenses under Section

the licenses granted to the Company under Section 7.1.1 with no
obligation to account to or pay royalties or other funds to the

joint owner of, the Product Marks and shall thereafter be free to
use and exploit the Product Marks on and in connection with the
VSC Technology and the VSC Products without obligation to the
other Member except that (aa) each Member shall adopt and
thereafter use one or more distinctive additional words in
conjunction with each Product Mark so as to distinguish the
Product Mark as used by such Member from the equivalent Product
Mark as used by the other Member in order to avoid confusion
amongst members of the public; and (bb) each Member agrees that
the goods and services it thereafter provides under the Product
Marks shall on the whole be of workmanlike quality that is
generally considered acceptable in the Education Market or, in
the alternative, shall not be significantly  lower in quality
than the products and services provided under the Product Marks
before dissolution or liquidation of the Company. Each Member
shall be entitled to register its distinctive variations of the
Product Marks in its individual name, and the other Member shall
not oppose any such application for registration and shall
cooperate by signing truthful affidavits in support of such
application if requested to do so.

                           ARTICLE XI
                           COVENANTS

    11.1.      Covenants.  For and in consideration of the
issuance of the Membership Interest by the Company to the
Members, all of the matters contained in this Operating
Agreement, and the information each Member will obtain as a
Member of the Company, each Member acknowledges and agrees to
comply with the terms of this Article XI.  Each Member recognizes
and agrees that it would be detrimental to its investment in the
Company for another Member to compete with the Company, either
during or after a Member's ownership of its Membership Interest.
Therefore, for and in consideration of the mutual covenants
contained herein and all the matters in this Agreement, the
Members agree to the provisions of this Article XI.  Each Member
recognizes and agrees that the restrictions and covenants
contained in this Article XI are reasonable and necessary for the
protection of the legitimate business interests and good will of
the Company, and each Member acknowledges that the mutual
covenants and restrictions contained in this Article XI are full
and adequate consideration for the covenants and restrictions
binding that Member.

    11.2.   Acknowledgment.  Each Member acknowledges that the
Company develops and licenses the VSC Technology, and that a
Member's status as a Member will give the Member access to client
names, file information and work, and the agreements and
covenants in this Article XI are essential to protect the
business and good will of the Company.

    11.3.   Competing Business.  During the time a Member owns a
Membership Interest of the Company, a Member will not, directly
or indirectly, compete with the Company in the Territory in the
sale or license of VSC Technology to third parties; provided MI
shall be entitled to create, develop, license, sell, utilize and
otherwise exploit other Technology or systems to accomplish the
same or similar purpose as the VSC Technology, including, but not
limited to, online testing and other scoring systems (the "MI
Rights").  This Section 11.3 shall not prohibit permitted
activities under the MI DMR License Agreement, the MI VSC License
Agreement or the TMS VSC License Agreement.

    11.4.      Extended Restrictions.  A Member who ceases to be
a Member for any reason other than liquidation or dissolution of
the Company shall comply with the restrictions set forth in
Section 11.3 in the Territory for a period of twenty-four (24)
months after the closing of the transfer of the Member's
Membership Interest in accordance with the provisions of this
Agreement.

    11.5.      Ownership of Information.   Except as otherwise
provided in this Agreement, all memoranda, notes, lists, records
and other documents or papers (and all copies thereof), including
such items stored in computer memory, microfiche, or by any other
means, made or compiled by or on behalf of Member or made
available to a Member relating to the Company are and shall be
the Company's property and shall be delivered to the Company
promptly upon the termination of a Member's status as a Member of
the Company or at any other time upon request by the Company.

<PAGE>  41

    11.6.   Validity.  The provisions and clauses of this
Article XI are separate and independent covenants and the
invalidity or unenforceability of any one or more of the
provisions or clauses hereof shall not affect the validity or
enforceability of the remaining provisions or clauses.  If the
court determines that any other covenants or any part thereof is
unenforceable because of the duration or geographic scope, such
court shall have the power to reduce the duration or scope of
such provision, as the case may be, and in its reduced form such
provision shall then be enforceable.

    11.7.      Tolling.  The Term shall be tolled during any
period of violation by a Member and/or any period of litigation
required to enforce the Member's obligations under this Article
XI.

                          ARTICLE XII
                         MISCELLANEOUS

independent accountants for the Company.

the Certificate of Formation will be valid or binding upon the
Members or the Company, nor will any waiver of any term of this
Agreement be effective, unless in writing and signed by each
Member.

    12.5.      Additional Documents.  Each party hereto agrees
to execute and acknowledge all documents and writings which the
Members may deem necessary or expedient in the creation of the
Company and the achievement of its purposes, including but not

cancellation thereof.

the contrary, this Agreement shall be binding upon and inure to
