                     (a) In addition to the actions specifically provided for
elsewhere in this Agreement, each of the parties hereto shall use commercially
reasonable efforts, prior to, on and after the date hereof, to take, or cause to
be taken, all actions, and to do, or cause to be done, all things, reasonably
necessary, proper or advisable under applicable laws, regulations and agreements
to consummate and make effective the transactions contemplated by this Agreement
and the Ancillary Agreements, including execution of Conveyancing Instruments
relating to the assumption by MMI Holdings and MMI of MMI Assumed Liabilities

                     (b) Without limiting the foregoing, prior to, on and after
the date hereof, each party hereto shall cooperate with each other party hereto,
and without any further consideration, but at the expense of the requesting
party, to execute and deliver, or use commercially reasonable efforts to cause
to be executed and delivered, all instruments, including instruments of
conveyance, assignment and transfer, and to make all filings with, and to obtain
all consents, approvals or authorizations of, any Governmental Authority or any
other Person under any permit, license, agreement, indenture or other instrument
(including any Consents or Governmental Approvals), and to take all such other
actions as such party may reasonably be requested to take by any other party

Ancillary Agreements, in order to effectuate the provisions and purposes of this
Agreement and the Ancillary Agreements and the transfer of the MMI Assets, and
the assignment and assumption of the MMI Assumed Liabilities and the other
transactions contemplated hereby and thereby. Without limiting the foregoing,
each party will, at the reasonable request, cost and expense of any other party,
use commercially reasonable efforts to take such other actions as may be
reasonably necessary to vest in such other party good and marketable title, free
and clear of any Security Interest other than a Security Interest securing a MMI
Assumed Liability, if and to the extent it is practicable to do so. In the event
and to the extent that any such required consent, approval or authorization to
assign and assume an agreement, lease, commitment or obligation which is an MMI
Asset or MMI Assumed Liability is not obtained, (i) Stream International or its
applicable Subsidiary shall continue to be bound thereby and (ii) from and after

discharge fully all the obligations of Stream International or its applicable
Subsidiary thereunder and MMI Holdings and MMI shall indemnify, as set forth in

or its applicable Subsidiary shall, without the payment of any further
consideration, pay and remit to MMI promptly any monies, rights and other
considerations received by Stream International or its applicable Subsidiary in
respect of such performance. Stream International or its applicable Subsidiary
shall exercise or exploit its rights and options under all such third party
agreements, leases, licenses and other rights and commitments referred to in
this Section 2.1.4(b) which are MMI Assets only as reasonably directed by MMI
and at MMI's expense. If and when any such Consent or Governmental Approval
shall be obtained or such agreement, lease, license or other right shall
otherwise become assignable or be able to be novated, Stream International or
its applicable Subsidiary shall promptly assign and novate all its rights and
obligations thereunder to MMI Holdings or its Subsidiaries without payment of
further consideration and MMI Holdings or its Subsidiaries shall, without the
payment of any further consideration, assume such rights and obligations.

Stream International shall, and shall cause each of its Affiliates after the

of this Agreement as a taxable exchange, and not as a transaction described in
Section 351 of the Code, for federal income tax purposes (and all other
applicable income tax purposes) and (ii) file Form 8594, and all their
respective federal, state, local and other Tax Returns required to be filed.

          2.1.6      Allocation of Cash.  Notwithstanding anything herein to the
                     ------------------
contrary, but subject to Section 3.2 hereof, the consolidated aggregate cash
held by Stream International and its Subsidiaries as of October 31, 1997, shall
be allocated to the particular business (i.e., the CST Business, the MMI
Business or the Stream International Business) that generated such cash,
provided that the maximum amount allocated to CST pursuant to this sentence
shall be $7,500,000, the maximum amount allocated to MMI pursuant to this
sentence shall be $12,500,000 and the maximum amount allocated to Stream
International pursuant to this sentence shall be $5,000,000 (such amounts are
hereinafter referred to as the "Target Amounts").  If any business has generated
cash in excess of its Target Amount, such excess shall be allocated to the other
businesses, pro rata based on the ratio of their Target Amounts, until one of
such businesses has been allocated its Target Amount.  Any remaining excess
shall be allocated to the remaining business until it has been allocated its
Target Amount.  If the consolidated aggregate cash held by Stream International
and its Subsidiaries as of October 31, 1997 exceeds $25,000,000, the amount in
excess of $25,000,000 shall be allocated 30% to CST, 50% to MMI and 20% to
Stream International.  Any cash generated after October 31, 1997 shall remain
with the particular business (i.e., the CST Business, the MMI Business or the
Stream International Business) that generated

                                       14
<PAGE>

such cash; provided, however, that the proceeds received by Stream International
pursuant to that certain Asset Purchase Agreement dated as of the date hereof
between Stream International and R.R. Donnelley Norwest, Inc. shall be allocated
40% to the MMI Business and 60% to the CST Business.

     2.2  Ancillary Agreements. On (except to the extent specified in
          --------------------
Section 2.1.3) the date hereof, Stream International, MMI Holdings and MMI, as
the case may be, shall enter into each of the Ancillary Agreements.

     2.3  Resignations.  At the request of Stream International, MMI Holdings
          ------------
shall cause all MMI Employees to resign effective on the date hereof from all
boards of directors or similar governing bodies of Stream International or any
Stream International Subsidiary on which they serve, and from all positions as
officers of Stream International or any Stream International Subsidiary in which
they serve.  At the request of MMI Holdings, Stream International shall cause
all of its own and all of the Stream International Subsidiaries' employees and
directors (other than MMI Employees and those directors of Stream International
who will continue to serve as directors of MMI or MMI Holdings) to resign
effective on the date hereof from all boards of directors or similar governing
bodies of MMI Holdings or any MMI Subsidiary on which they serve, and from all
positions as officers of MMI Holdings or any MMI Subsidiary in which they serve.

     2.4  Transfers Not Effected on or Prior to the Drop-down.  Nothing herein
          ---------------------------------------------------
shall be deemed to require the transfer of any Assets or the assumption of any
Liabilities which by their terms or operation of law cannot be transferred or
assumed; provided, however, that Stream International and MMI Holdings and their
         --------  -------
respective Subsidiaries shall cooperate to seek to obtain any necessary Consents
or Governmental Approvals for the transactions contemplated by this Article 2.
In the event that any transfer of Assets or Liabilities has not been
consummated, effective as of or prior to the date hereof, the party retaining
such Asset or Liability shall thereafter hold such Asset for the party entitled
thereto (at the expense of the party entitled thereto) and retain such Liability
for the account of the party by whom such Liability is to be assumed (at the
expense of the party to whom such Liability is to be transferred), and each
party will take such other action as may be reasonably requested by the other
party in order to place the party to whom such Asset is to be transferred, or by
whom such Liability is to be assumed, as the case may be, insofar as reasonably
possible, in the same position as would have existed had such Asset or Liability
been transferred as of the date hereof.  As and when any such Asset or Liability
becomes transferable, such transfer shall be effected forthwith.

     2.5  No Representations or Warranties; Consents.  MMI Holdings understands
          ------------------------------------------
and hereby agrees that Stream International is not, in this Agreement or in any
other agreement or document contemplated by this Agreement or otherwise, nor

law (i) as to the value or freedom from encumbrance or Security Interest of, or
any other matter concerning, any of the MMI Assets transferred or to be
transferred to MMI Holdings as contemplated by this Article 2 or (ii) as to the
legal sufficiency to convey title to any such Asset of the execution, delivery
and filing of this Agreement or any Ancillary Agreement, including, without
limitation, any Conveyancing Instruments, IT BEING UNDERSTOOD AND HEREBY AGREED
THAT ALL MMI ASSETS ARE BEING TRANSFERRED "AS IS, WHERE IS" and that MMI
Holdings shall bear the economic and legal risk that any conveyances of such
Assets shall prove to be insufficient or that MMI Holdings or any of its
Subsidiaries' title to any such assets shall be other than good and marketable
and free from encumbrances or Security Interests.  Similarly, MMI Holdings
understands and hereby agrees that Stream International is not, in this
Agreement or in any other agreement or document contemplated by this Agreement
or otherwise, nor shall Stream International be deemed or implied to be,
representing or warranting in any way that the obtaining of any Consents or
Governmental Approvals, the execution and delivery of any amendatory agreements
and the making of any filings or applications contemplated by this Agreement or
such other agreements or documents shall satisfy the provisions of any or all
applicable agreements or the requirements of any or all applicable laws or
judgments, it being understood and hereby agreed that MMI Holdings and the MMI
Subsidiaries shall bear the economic and legal risk that any necessary Consents
or Governmental Approvals are not obtained or that any requirements of laws or
judgments are not complied with. Notwithstanding the foregoing, the parties
shall use reasonable efforts to obtain all Consents and Governmental Approvals,
to enter into all amendatory agreements and to make all filings and applications
which may be required for the consummation of the transactions contemplated by
this Agreement.

     2.6  Insurance.  MMI agrees that it will purchase, to the extent available
          ---------
at a reasonable cost, insurance policies to be in effect as of the Distribution
Date which provide substantially the same types of coverage as the policies
maintained by Stream International or R.R. Donnelley under the Insurance Program
with respect to the MMI Business, including without limitation any insurance
required by any lease of real or personal property.  Stream International shall,
if so requested by MMI, use reasonable efforts to assist MMI in obtaining such
initial insurance coverage for MMI from and after the Distribution in such
amounts as are agreed upon by Stream International and MMI.  Following the
Distribution, each of Stream International and MMI shall cooperate with and
assist the other party in the prevention of conflicts or gaps in insurance
coverage and/or collection of proceeds.

     2.7  Stock Options.  Prior to the Distribution, Stream International shall
          -------------
adjust each Stream International Option by reducing to $4.86 the per share
exercise price for such option (other than options with exercise prices at or
above $4.86 per share and options held by Messrs. Cowan, Leahy, Moore and
Rosenthal and certain

                                       16
<PAGE>

options held by Mr. Morphis) and by providing, with respect to those option
holders who will be employed by MMI Holdings, CST Holdings or their Subsidiaries
following the Distribution, that the option terminates three months after the
option holder ceases to be employed by MMI Holdings or CST Holdings or their
Subsidiaries, as the case may be (each such option, as so adjusted prior to the
Distribution Date, the "Adjusted Option").

     In connection with the Distribution, each Stream International Option to
purchase shares of Class A Common Stock of Stream International shall be
supplemented with an option to purchase an identical number of shares of voting
stock of each of CST Holdings and MMI Holdings, and each Stream International
Option to purchase shares of Class B Common Stock of Stream International shall
be supplemented with an option to purchase such number of shares of voting stock
of each of CST Holdings and MMI Holdings as is equal to the number of shares of
Class A Common Stock into which the shares of Class B Common Stock covered by
such option would be convertible at the conversion rate fixed on the date of the
Drop-down (collectively, the "Additional Options").  The per share exercise
price for the Additional Options shall be equal to the product determined by
multiplying the exercise price per share of Stream International Common Stock at
which such Stream International Option was exercisable by 11.93% in the case of
the Additional Option granted by MMI Holdings and 38.48% in the case of the
Additional Option granted by CST Holdings.  The per share exercise price for
each Stream International Option shall be reduced by an amount equal to the
aggregate exercise price of the Additional Options granted in respect of such
option.  The Additional Options shall be subject to the terms of the MMI
Holdings and CST Holdings 1997 Class A Replacement Stock Option Plans, 1997
Class A California Replacement Stock Option Plans and 1997 Class B Replacement
Stock Option Plans, as applicable.

     Notwithstanding all the foregoing in this Section 2.7, if the holder of an
outstanding Stream International Option does not consent in writing to the
adjustment of such holder's option in accordance with the foregoing, such
holder's option shall not be adjusted and no Additional Options shall be granted
to such holder.

     Upon termination of employment of any employee of MMI Holdings or any MMI
Subsidiary who has an Adjusted Option, MMI Holdings shall provide to Stream
International and CST the name of such employee and the date the employee ceased
employment with MMI Holdings or any MMI Subsidiary and shall indicate whether
the termination was for cause.  Upon Stream International's request from time to
time, MMI shall also provide a complete list of employees of MMI Holdings or any
MMI Subsidiary who have Adjusted Options, which list shall show such holder's
name, Social Security number and address and shall include such other
information as Stream International shall reasonably request.

                                       17

Security number and address and shall include such other information as MMI

liability following the date hereof, whether as a primary obligor, guarantor or
otherwise with respect to any lease of real property to which MMI Holdings or a
MMI Subsidiary is a party on the date hereof or which is assigned or purported
to be assigned to MMI Holdings or a MMI Subsidiary pursuant to this Agreement or
any Ancillary Agreement, MMI Holdings or the MMI Subsidiary, as the case may be,

MMI Holdings represents that, and the Chief Financial Officer or Treasurer of
MMI shall deliver a Certificate stating that, the Audited Financial Statements
and Unaudited Financial Statements are complete and correct, are in accordance
with the books and records of MMI and present fairly the financial condition and
results of operations of MMI, as at the dates and for the periods indicated, and
have been prepared in accordance with generally accepted accounting principles
consistently applied, except that the Unaudited Financial Statements have been
prepared for the internal use of management and may not be in accordance with
generally accepted accounting principles because of the absence of footnotes
normally contained therein and are subject to normal year-end audit adjustments
which in the aggregate will not be material.

                   CERTAIN EMPLOYEE AND BENEFIT PLAN MATTERS


     3.1  Certain MMI Plans; Assumption of Obligations by MMI.  Stream
          ---------------------------------------------------
International or its Subsidiaries maintain the Employee Benefit Plans listed on
Schedule 3.1 hereto for the benefit of the U.S. employees of the MMI Business
(the "MMI Benefit Plans").  Except as provided in Section 3.4 with respect to
the Stream Savings Plan, and concurrently with the action described in Section
2.1.1, Stream International will transfer and assign all MMI Benefit Plans to
MMI Holdings, and MMI Holdings will immediately thereafter transfer and assign
all MMI Benefit Plans to MMI and MMI will (i) accept such transfer and
assignment, (ii) assume and adopt all MMI Benefit Plans, (iii) assume any
Liabilities with respect to such MMI Benefit Plans whether arising before or
after the date hereof and (iv) assume any Liabilities arising (whether before or
after the date hereof) under any Employee Benefit Plan maintained by Stream
International or its Subsidiaries, which is not a MMI Benefit Plan, to the
extent related to MMI Employees and Former MMI Employees including, but not
limited to, under any Employee Benefit Plans maintained up to the date hereof by
Stream International or its Subsidiaries under the laws of any country other
than the United States (the "MMI Foreign Benefit Plans") with respect to MMI
Employees or Former MMI Employees.  Nothing in this Agreement shall be construed
to prevent MMI from altering or discontinuing any MMI Benefit Plan or MMI
Foreign Benefit Plan after the Distribution Date, provided that such alteration
or discontinuance relates only to MMI Employees or Former MMI Employees.  In
addition to the Liabilities assumed pursuant to the foregoing, MMI will assume
all Liabilities relating to any Employee Benefit Plan of Stream International or
its Subsidiaries which relate to matters occurring prior to the Distribution,
such as any Liabilities arising in connection with the administration of any
Employee Benefit Plan, to the extent such Liabilities do not relate solely to
the CST Business or the Stream International Business or do not relate solely to
a specific employee of the CST Business or the Stream International Business.

     3.2  Certain Payments by Stream International.  Stream International and
          ----------------------------------------
its Subsidiaries hereby agree to continue making all regular payments, whether
for insurance premiums, benefits, expenses or other related purposes to (i) any
MMI Benefit Plan, or (ii) any Employee Benefit Plan maintained by Stream
International or its Subsidiaries, with respect to any participating MMI
Employee or participating Former MMI Employee through the date hereof,
consistent with the manner and timing of such payments which are made with
respect to any employee or former employee of Stream International or its

                                       19
<PAGE>

Subsidiaries who are participating in the same or comparable Employee Benefit
Plans maintained by Stream International or its Subsidiaries.  The amount of any
such payments made after November 30, 1997, or made prior to such date to the
extent relating to any period following such date, shall be deducted from the
cash allocated to MMI pursuant to Section 2.1.6 and added to the cash allocated
to Stream International pursuant to such Section 2.1.6.  In addition, Stream
International and its Subsidiaries shall continue to make such payments with
respect to any MMI Employee whose employment is transferred from Stream
International or any of its Subsidiaries to MMI or any MMI Subsidiary within 12
months through the date hereof until the date of such transfer.

     3.3  Employees on Certain Leave.  If any individual who becomes a MMI
          --------------------------
Employee is on a leave of absence approved by Stream International or any of its
Subsidiaries on his or her Transfer Date and continues on a leave approved by
MMI or any MMI Subsidiary after the Transfer Date, then such leave shall
continue under MMI's leave policies and MMI shall assume any liability for any
benefits provided by Stream International or any Stream International Subsidiary
prior to the Transfer Date or any benefits required to be provided to such MMI
Employee by law; provided that the maximum amount and duration of such benefits
as well as the duration of the leave provided before and after the Transfer Date
shall not exceed the limits under the applicable Stream International or Stream
International Subsidiary policy.

     3.4  Stream Savings Plan.
          -------------------

          3.4.1      Creation of Multiple Employer Plan.  The Stream Savings
                     ----------------------------------
and Retirement Program was established for the benefit of all U.S. employees of
Stream International and its Subsidiaries under Section 401(k) of the Code (the
"Stream Savings Plan").  On the date hereof the Stream Savings Plan will be
adopted by MMI Holdings, the MMI Subsidiaries, CST Holdings and the CST
Subsidiaries as additional plan sponsors.  Therefore, the Stream Savings Plan
will then be maintained by a controlled group of corporations as defined under
Section 414 of the Code ("Controlled Group") as well as corporations that are
not part of the Controlled Group.  In addition, Stream International has
approved the amendment of the Stream Savings Plan, effective upon the
Distribution Date, into a multiple employer plan in order to continue to provide
benefits under the terms of the Stream Savings Plan, as amended, for employees
or former employees of any of the corporations that have adopted the Stream
Savings Plan, which corporations, as of the Distribution Date, or thereafter,
cease to be a member of the Controlled Group that includes Stream International.
All assets of the Stream Savings Plan will continue to be maintained in the
existing trust established thereunder.

          3.4.2      Subsequent Contributions.  After the date hereof, MMI
                     ------------------------
Employees will continue to make contributions to the Stream Savings Plan,
without interruption, based on elections made by them in accordance with the
terms of the Stream Savings Plan.  Each MMI Employee who is making salary
reduction contributions to the Stream Savings Plan immediately prior to his or
her Transfer

                                       20
<PAGE>

Date, with respect to compensation paid on or before such Transfer Date, and who
continues to be employed by MMI or a MMI Subsidiary until the end of the
calendar quarter in which such Transfer Date occurs, will have matching
contributions made to the Stream Savings Plan as of the end of such calendar
quarter by MMI, with respect to all such contributions made during such calendar
quarter. Stream International shall cease making any matching contributions with
respect to MMI Employees' salary reduction contributions after making its
matching contribution for the calendar quarter which ends immediately prior to
the calendar quarter which includes the Transfer Date of MMI Employees.

          3.4.3      New Savings Plan.  No later than March 31, 1998, MMI shall
                     ----------------
establish a new savings plan under Section 401(k) of the Code with such terms
and conditions, subject to the limitations of Code Section 411(d)(6), as MMI may
provide and all contributions with respect to MMI Employees will thereafter be
made to such new savings plan (the "New MMI Savings Plan").  No later than March
31, 1998, MMI shall direct the trustee of the trust established under the Stream
Savings Plan to transfer to the trust established under the New MMI Savings
Plan, in such manner and at such time as the trustee of the New MMI Savings Plan
and the trustee of the Stream Savings Plan shall reasonably agree, any Assets
and Liabilities allocable to the individual accounts maintained with respect to
participants and beneficiaries in the Stream Savings Plan who are MMI Employees
or Former MMI Employees, subject to the requirements of Section 414 of the Code.

     3.5  Employee Matters.  MMI agrees to (i) be solely responsible for all
          ----------------
employment law compliance with respect to the transfer of all MMI Employees; and
(ii) to assume any Liabilities, whether arising before or after the date hereof,
with respect to any MMI Employee or Former MMI Employee related to (a )
employment with Stream International or any of its Subsidiaries, including,
without limitation, any accrued vacation or severance pay, and (b) the transfer
of employment to MMI or any MMI Subsidiary or any subsequent termination of such
employment.

     3.6  Information Regarding Certain Former Employees of R.R. Donnelley.
          ----------------------------------------------------------------
MMI (or, if applicable, its Subsidiaries) shall assume the obligations under
Section 7.2(b)(3) of the 1995 Contribution Agreement including, without
limitation, the obligation to provide information relating to the termination of
an Eligible RRD Newco Employee (as defined in Section 7.2(b)(6) of the 1995
Contribution Agreement) who is a MMI Employee.  Such termination information
shall be provided to R.R. Donnelley as such information is available to MMI or
any of its Subsidiaries.

                               THE DISTRIBUTION

     4.1  Action Prior to the Distribution.  Stream International and MMI
          --------------------------------
Holdings shall take all such action (if any) as may be necessary or appropriate
under the securities or blue sky laws of the United States or any individual
state (and any comparable laws under any foreign jurisdiction) in connection
with the Distribution.

     4.2  Stream International Board Action; Conditions Precedent to the
          --------------------------------------------------------------
Distribution.  The Stream International Board shall, in its discretion,
------------
establish the Record Date and the Distribution Date and any appropriate
procedures in connection with the Distribution.  The consummation of the
Distribution shall be subject to the consummation in all material respects of
each of  the transactions contemplated by Article 2 hereof that are required to
be consummated prior to the Distribution; provided, however, that the
                                          --------  -------
satisfaction of such condition shall not create any obligation on the part of
Stream International to effect the Distribution or in any way limit Stream
International's power to abandon the Distribution as set forth in Section 7.8
hereof.

                                INDEMNIFICATION

     5.1  Indemnification by Stream International for Stream International
          ----------------------------------------------------------------
Liabilities.  Except as set forth in the Services Agreement between SISC and
-----------
MMI, Stream International shall indemnify, defend and hold harmless MMI Holdings
and each Affiliate of MMI Holdings (including the MMI Subsidiaries) and each of
their respective directors, officers, employees and agents and each of the
heirs, executors, successors and assigns of any of the foregoing (the "MMI
Indemnitees") from and against any and all losses, claims, damages, obligations,
payments, costs and expenses, matured or unmatured, absolute or contingent,
accrued or unaccrued, liquidated or unliquidated, known or unknown (including,
without limitation, the costs and expenses of any and all Actions, threatened
Actions, demands, assessments, judgments, settlements and compromises relating
thereto and reasonable attorneys' fees and any and all expenses whatsoever
reasonably incurred in investigating, preparing or defending against any such
Actions or threatened Actions) (collectively, "Indemnifiable Losses") of the MMI
Indemnitees (i) arising out of or due to the failure or alleged failure of
Stream International or any of its Affiliates to pay, perform or otherwise
discharge in due course any Stream International Liabilities or (ii) arising out
of Stream International's or any Stream International Subsidiary's performance
of,

                                       22
<PAGE>

or failure to perform, any of its covenants or agreements contained in this
Agreement.

     5.2  Indemnification by MMI for MMI Liabilities.  Except as set forth in
          ------------------------------------------
the Services Agreement between SISC and MMI, MMI Holdings and MMI shall jointly
and severally indemnify, defend and hold harmless Stream International and each
Affiliate of Stream International (including the Stream International
Subsidiaries) and each of their respective directors, officers, employees and
agents and each of the heirs, executors, successors and assigns of any of the
foregoing (the "Stream International Indemnitees") from and against any and all
Indemnifiable Losses (i) arising out of or due to the failure or alleged failure
of MMI Holdings or any of its Affiliates to pay, perform or discharge any MMI
Assumed Liability (without regard to whether all applicable Consents and
Governmental Approvals relating to the assumption thereof have been obtained);
(ii) arising out of the failure to obtain any Consents or Governmental Approvals
required for the Drop-down and the Distribution; (iii) arising out of any
violation or alleged violation of applicable laws, regulations, rules or orders
of a Governmental Authority, including, but not limited to, federal or state
securities law, in connection with the transactions contemplated by this
Agreement, including the Drop-down and the Distribution (other than in
connection with the Stream IPO); (iv) arising out of MMI Holdings' or any MMI
Subsidiary's performance of, or failure to perform, any obligations described in
Section 2.1.4(b)(ii) hereof; (v) arising out of or related to the contingent
liabilities referred to in Section 2.8 hereof or (vi) arising out of MMI
Holdings' or any MMI Subsidiary's performance of, or failure to perform, any of
its covenants or agreements contained in this Agreement.

     5.3  Limitations on Indemnification Obligations.  The amount which any
          ------------------------------------------
party (an "Indemnifying Party") is required to pay to any MMI Indemnitee or
Stream International Indemnitee (an "Indemnitee") pursuant to Sections 5.1 or
5.2 hereof shall be reduced (including, without limitation, retroactively) by
any insurance proceeds or other amounts actually recovered by or on behalf of
such Indemnitee in reduction of the related Indemnifiable Loss.  To the extent
an Indemnifying Party makes full payment in respect of an Indemnifiable Loss and
such Indemnifiable Loss is covered by an insurance policy which has not been the
subject of an effective assignment to the Indemnifying Party, at the request of
the Indemnifying Party, the Indemnitee shall use commercially reasonable efforts
at the expense of the Indemnifying Party (which expenses shall be deemed to
include any increase in insurance premiums of the Indemnitee attributable to the
filing of such claims) to enforce any and all claims under such insurance policy
in respect of such Indemnifiable Loss for the benefit of the Indemnifying Party.
If any Indemnitee shall have received the full payment required by this
Agreement from an Indemnifying Party in respect of an Indemnifiable Loss and
shall subsequently actually receive insurance proceeds or other amounts in
respect of such Indemnifiable Loss, then such Indemnitee shall pay to such
Indemnifying Party a sum equal to the amount of such insurance proceeds or

                                       23
<PAGE>

other amounts actually received (net of any expenses in obtaining the same), but
not to exceed the net amount of the payments previously received by the
Indemnitee from the Indemnifying Party in respect of such Indemnifiable Loss. An
insurer who would otherwise be obligated to pay any claim shall not be relieved
of the responsibility with respect thereto or, solely by virtue of the
indemnification provisions hereof, have any subrogation rights with respect
thereto, it being expressly understood and agreed that no insurer or any other
third party shall be entitled to a "windfall" (i.e., a benefit they would not be
entitled to receive in the absence of the indemnification provisions) by virtue
of the indemnification provisions hereof. Nothing herein shall require an
Indemnitee to enforce claims under an insurance policy before proceeding to
enforce its rights to indemnification against an Indemnifying Party.

     5.4  Procedure for Indemnification.
          -----------------------------

          5.4.1      Third Party Claims; Notice.  If an Indemnitee shall
                     --------------------------
receive notice or otherwise learn of (i) a default or breach by an Indemnifying
Party under any agreement or instrument with a third party to which the
Indemnifying Party is a party, (ii) the assertion by any other Person of any
claim other than a claim relating to Taxes or (iii) the commencement by any such
Person of any Action (other than an Action relating to Taxes) (clauses (i), (ii)
and (iii) are each hereinafter referred to as a "Third Party Claim") with
respect to which an Indemnifying Party may be obligated to provide
indemnification pursuant to this Article 5, such Indemnitee shall give such
Indemnifying Party written notice thereof within 10 business days after becoming
aware of such Third Party Claim ("Third Party Claim Notice"); provided, however,
                                                              --------  -------
that the failure of any Indemnitee to give notice as provided in this Section
5.4.1 shall not relieve the related Indemnifying Party of its obligations under
this Article 5, except to the extent that such Indemnifying Party actually is
prejudiced by such failure to give notice.  Such notice shall describe the Third
Party Claim in reasonable detail, and shall indicate the amount (estimated if
necessary) of the Indemnifiable Loss that has been or may be sustained by such
Indemnitee.  Thereafter, such Indemnitee shall deliver to such Indemnifying
Party, within five business days after the Indemnitee's receipt thereof, copies
of all notices and documents (including court papers) received by the Indemnitee
relating to the Third Party Claim.

     The Indemnifying Party shall have a period of 20 days after the receipt of
a Third Party Claim Notice within which to respond thereto.  If such
Indemnifying Party does not respond within such 20-day period, such Indemnifying
Party shall be deemed to have accepted responsibility to indemnify the
Indemnitee in respect of the claims specified in the Third Party Claim Notice
and shall have no further right to contest its obligation in respect thereof.
If such an Indemnifying Party does respond within such 20-day period and
disputes such claim in whole or in part, the Indemnitee and the Indemnifying
Party shall resolve the portion of the claim which is disputed in accordance
with the provisions of Section 5.4.9 hereof.

                                       24
<PAGE>

          5.4.2      Defense of Third Party Claims.  In case any Third Party
                     -----------------------------
Claim is brought against an Indemnitee and the Indemnifying Party has not
disputed its obligation to indemnify the Indemnitee with respect to any part of
such Third Party Claim, the Indemnifying Party will be entitled to participate
in and to assume the defense thereof to the extent that it may wish, with
counsel reasonably satisfactory to such Indemnitee, and after notice from an
Indemnifying Party to such Indemnitee of its election so to assume the defense
thereof and for so long as the Indemnifying Party diligently pursues such
defense, such Indemnifying Party will not be liable to such Indemnitee for any
legal or other expenses subsequently incurred by such Indemnitee in connection
with the defense thereof; provided, however, that, if the defendants in any such
                          --------  -------
claim include both the Indemnifying Party and one or more Indemnitees and in any
Indemnitee's reasonable judgment a conflict of interest between one or more of
such Indemnitees and such Indemnifying Party exists in respect of such claim,
such Indemnitees shall have the right to employ separate counsel to represent
such Indemnitees, and in that event the reasonable fees and expenses of such
separate counsel (but not more than one separate counsel reasonably satisfactory
to the Indemnifying Party for all Indemnitees with respect to any single Third
Party Claim or group of consolidated related Third Party Claims) shall be paid
by such Indemnifying Party.  If the Indemnifying Party undertakes to assume the
defense of a Third Party Claim, it shall promptly notify the Indemnitee in
writing of its intention to do so.

          5.4.3      Cooperation by Indemnitee.  If an Indemnifying Party
                     -------------------------
chooses to defend or to seek to compromise or settle any Third Party Claim, each
related Indemnitee shall make available to such Indemnifying Party any personnel
or any books, records or other documents within its control or which it
otherwise has the ability to make available that are necessary or appropriate
for such defense, settlement or comprise, and shall otherwise cooperate in the
defense, settlement or compromise of such Third Party Claim.

          5.4.4      Limitation on Authority to Settle Claim.  Notwithstanding
                     ---------------------------------------
anything else in this Section 5.4 to the contrary, neither an Indemnifying Party
nor an Indemnitee shall settle or compromise any Third Party Claim over the
objection of the other; provided, however, that consent to compromise or
                        --------  -------
settlement shall not be unreasonably withheld, except that consent to any
compromise or settlement involving equitable or injunctive relief against any
Indemnifying Party or Indemnitee may be withheld by such Indemnifying Party or
Indemnitee for any reason.  No Indemnifying Party shall consent to any judgment
or enter into any settlement or compromise which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to each
related Indemnitee of a written release from all Liability with respect to such
Third Party Claim.

          5.4.5      Other Claims.  Any claim on account of any Indemnifiable
                     ------------
Loss which does not result from a Third Party Claim shall be asserted by written
notice

                                       25
<PAGE>

given by the Indemnitee to the related Indemnifying Party ("Claim Notice"). Such
Indemnifying Party shall have a period of 20 days after the receipt of the Claim
Notice within which to respond thereto. If such Indemnifying Party does not
respond within such 20-day period, such Indemnifying Party shall be deemed to
have accepted responsibility to make payment and shall have no further right to
contest the validity of such claim. If such Indemnifying Party does respond
within such 20-day period and disputes such claim in whole or in part, the
Indemnitee and the Indemnifying Party shall resolve the portion of the claim
which is disputed in accordance with the provisions of Section 5.4.9 hereof.

          5.4.6      Advancement of Certain Expenses.  Upon the written demand
                     -------------------------------
of an Indemnitee, an Indemnifying Party shall reimburse or advance funds to such
Indemnitee for all Indemnifiable Losses reasonably incurred by it in connection
with investigating or defending any Third Party Claim in advance of its final
disposition; provided, however, that such reimbursement need be made only upon
             --------  -------
delivery to the Indemnifying Party of an undertaking by such Indemnitee to repay
all amounts so reimbursed or advanced if it shall ultimately be determined that
such Indemnitee is not entitled to indemnification under this Article 5 or
otherwise.

          5.4.7      Subrogation to Rights of Indemnitee.  In the event of
                     -----------------------------------
payment by an Indemnifying Party to any Indemnitee in connection with any Third
Party Claim of the full amount payable under this Article 5 in respect thereof,
such Indemnifying Party shall be subrogated to and shall stand in the place of
such Indemnitee as to any events or circumstances in respect of which such
Indemnitee may have any right or claim relating to such Third Party Claim
against any claimant or plaintiff asserting such Third Party Claim or as against
any other Person.  In such event, such Indemnitee shall cooperate with such
Indemnifying Party in a reasonable manner, and at the cost and expense of such
Indemnifying Party, in prosecuting any subrogated right or claim.

          5.4.8      Named Parties.  The parties hereto acknowledge that it may
                     -------------
not be feasible to substitute MMI for Stream International as a named party in
any existing Actions constituting MMI Assumed Liabilities.  In such event,
Stream International shall remain as a named party and will be able to
participate in the defense of such Action (with the liability regarding the
legal or other expenses for such participation to be determined pursuant to
Section 5.4.2 hereof), but following the date hereof, MMI Holdings and MMI shall
assume the defense of any such Action in accordance with the provisions of this
Section 5.4 and Stream International and its Affiliates shall cooperate with MMI
Holdings and MMI as contemplated by Section 5.4 and Article 6 hereof.

          5.4.9      Dispute Resolution.  If an Indemnifying Party disputes all
                     ------------------
or part of a Third Party Claim pursuant to Section 5.4.1 or all or part of a
claim other than a Third Party Claim pursuant to Section 5.4.5, such dispute
shall be resolved in

                                       26
<PAGE>

accordance with the procedure set forth in this Section 5.4.9. Within 10 days
after notice by the Indemnifying Party that it disputes the claim in question,
the Indemnitee and the Indemnifying Party shall designate in writing one
arbitrator to resolve the dispute; provided that if the Indemnitee and the
Indemnifying Party cannot agree on an arbitrator within such 10-day period, the
arbitrator shall be selected by the Boston, Massachusetts, office of the
American Arbitration Association. The arbitrator so designated shall not be an
Affiliate of the Indemnitee or Indemnifying Party or any employee of, or
consultant to, the Indemnitee, the Indemnifying Party or any of their
Affiliates. Within 15 days after the designation of the arbitrator, the
Indemnitee, the Indemnifying Party and the arbitrator shall meet, at which time
the Indemnitee and the Indemnifying Party shall each be required to set forth in
writing all disputed issues and a proposed ruling on each such issue. The
arbitrator shall thereupon set a date for a hearing, which shall be no later
than 30 days after the submission of the written proposals described in the
immediately preceding sentence, to discuss each of the issues identified by the
Indemnitee and the Indemnifying Party. Each of the Indemnitee and the
Indemnifying Party shall have the right to be represented by counsel. The
arbitration shall be governed by the Commercial Arbitration Rules of the
American Arbitration Association; provided, however, that the arbitrator shall
have sole discretion with regard to the admissibility of evidence.

     The arbitrator shall use his or her best efforts to rule on each disputed
issue within 30 days after the completion of the hearing described in the
immediately preceding paragraph.  The determination of the arbitrator as to the
resolution of any dispute shall be binding and conclusive upon all parties
hereto.  All rulings of the arbitrator shall be in writing and shall be
delivered to the Indemnitee and the Indemnifying Party.  The attorneys' fees of
the Indemnitee and the Indemnifying Party in any arbitration shall be borne by
them as determined by the arbitrator, together with the fees of the arbitrator
and the costs and expenses of the arbitration.  Any arbitration pursuant to this
Section 5.4.9 shall be conducted in Boston, Massachusetts.  Any arbitration
award may be entered  in and enforced by any court having jurisdiction thereover
and shall be final and binding upon the parties.

          5.4.10     Determination of Time of Payment of Indemnitee.  With
                     ----------------------------------------------
respect to any claim made by an Indemnitee pursuant to this Article 5, the
Indemnifying Party shall have no further right to contest its obligations in
respect thereof (or a portion thereof, if applicable pursuant to clause (ii) of
this Section 5.4.10) following the occurrence of a Determination Event with
respect to such claim (or a portion thereof, if applicable pursuant to clause
(ii) of this Section 5.4.10), and the Indemnifying Party thereafter shall pay
all Indemnifiable Losses related to such claim or applicable portion thereof on
their respective Due Dates.  With respect to a reimbursement or advance of funds
made by an Indemnifying Party pursuant to Section 5.4.6, the Indemnifying Party
shall have no right to contest the right of the Indemnitee to indemnification
(and, hence, no right to demand repayment pursuant

                                       27
<PAGE>

to the proviso clause of Section 5.4.6) with respect to the claim to which the
reimbursement or advance relates (or portion thereof, if applicable pursuant to
clause (ii) of this Section 5.4.10) following the occurrence of a Determination
Event with respect to such claim (or portion thereof, if applicable pursuant to
clause (ii) of this Section 5.4.10). "Determination Event" shall mean the
earliest of (i) the failure of the Indemnifying Party to respond to a Third
Party Claim Notice or Claim Notice within the applicable 20-day period, (ii)
with respect to any portion of a claim, the failure of the Indemnifying Party to
dispute within the applicable 20-day period, its obligation to pay such portion
of the claim in its response to a Third Party Claim Notice or Claim Notice,
(iii) the written acknowledgment of the Indemnifying Party of its obligation
hereunder with respect to such claim or (iv) the decision of an arbitrator
pursuant to Section 5.4.9 hereof upholding the obligation of the Indemnifying
Party in respect of such claims. "Due Date" shall mean (a) with respect to a
Third Party Claim that has been assumed by the Indemnifying Party pursuant to
Section 5.4.2 hereof, as and when any sums related to such claim become due and
payable, (b) with respect to any Third Party Claim whose defense has not been
assumed by the Indemnifying Party, upon written demand by the Indemnitee and (c)
with respect to any claim on account of any Indemnifiable Loss which does not
result from a Third Party Claim, upon written demand therefor by the Indemnitee;
provided, however, that in no event shall the Due Date for any claim occur prior
--------  -------
to the Determination Event for such claim.

     5.5  Remedies Cumulative.  The remedies provided in this Article 5 shall
          -------------------
be cumulative and shall not preclude assertion by any Indemnitee of any other
rights or the seeking of any and all other remedies against any Indemnifying
Party; provided, however, that all remedies sought or asserted by an Indemnitee
       --------  -------
against an Indemnifying Party with respect to an Indemnifiable Loss shall be
limited by and be subject to the provisions of this Article 5.

     5.6  Nature of Indemnity Payments.  All payments by the Indemnifying Party
          ----------------------------
under Section 5.1 or 5.2 hereof shall be treated, to the maximum extent
allowable under applicable Tax laws, as an adjustment to the MMI Assets
contributed to MMI Holdings in connection with the Drop-down.  The amount of
each payment by the Indemnifying Party shall be computed after taking into
account all Tax consequences to the Indemnitee, or any Affiliate, of (i) the
receipt of (or the right to receive) the payment and (ii) the event or
incurrence of the liability that gave rise to the right to receive the payment.
In determining the Tax consequences to the Indemnitee, or any Affiliate, for
purposes of this Section 5.6, any Tax detriment, in the case of a payment, and
any Tax benefit, in the case of an event or an incurrence of a liability, shall
be taken into account in the taxable years or periods in which the Indemnitee,
or any Affiliate, is required to pay additional Taxes by reason of the payment,
or is entitled to a refund of Tax or a reduction in the amount of Taxes it would
otherwise be required to pay by reason of the event or the incurrence of the
liability.

fault of such party or (ii) later lawfully acquired from other sources by such
party), and each party shall not release or disclose such Information to any
other Person, except as reasonably required to its auditors, attorneys,
