          (i) except as provided below, Tax Items primarily related to the
Stream Business will be taken into account in determining Taxes related to the
Stream Business, Tax Items primarily related to the MMI Business will be taken
into account in determining Taxes related to the MMI Business, and Tax Items
primarily related to the CST Business will be taken into account in determining
Taxes related to the CST Business;



          (ii) Tax Items for any taxable period consisting of deductions
attributable to the exercise of compensatory options granted to employees of any
member of the Stream Affiliated Group to acquire shares of Stream, MMI Holdings
or CST Holdings shall be deemed to be primarily related to the Stream Business,
the MMI Business or the CST Business if a member of the Stream Group, the MMI
Group or the CST Group, respectively, most recently employed the exercising
employee at the time of exercise;



          (iii) except as otherwise provided in this Agreement, Tax Items not
primarily related either to the Stream Business, the MMI Business or the CST
Business will be taken into account 40% in determining Taxes related to the MMI
Business and 60% in determining Taxes related to the CST Business;



          (iv) in determining the Taxes related to the Stream Business, the MMI

<PAGE>

beginning at the beginning of the day after the end of the Short Period, in all
cases determined on a "closing of the books basis" at the end of the Short
Period (except that items computed on an annual basis, such as depreciation,
shall be allocated on a daily basis). For all purposes of this Agreement, the
portion of the Straddle Period ending at the end of the Short Period and the
portion of the Straddle Period beginning at the beginning of the day after the
end of the Short Period shall each be treated as a "taxable year or period";



          (v) the benefit of (A) the graduated tax rates of Code Section 11, (B)

Business and the CST Business for any period, (A) any net operating losses, net
capital losses, alternative minimum tax credits and other credits ("Loss
Attributes") carried back to such period from a Post-Drop-down Taxable Period of
the Stream Group shall be taken into account solely to determine the Taxes
related to the Stream Business to the extent that the Loss Attributes carried
back exceed Loss Items as defined in the Tax Reimbursement Agreement, (B) to the
extent that the Loss Attributes carried back do not exceed Loss Items, such Loss
Attributes shall first be used to eliminate or reduce Tax Items, if any, that,
absent this clause (B), would have resulted in the imposition of Reorganization
Taxes, and (C) any Loss Attributes carried back to which clause (A) does not
apply and which exceed the Tax Items described in clause (B) shall be treated
consistently with the principles set forth in Section 3.01(d)(vii), below (see
Annex A to the Tax Reimbursement Agreement for examples applying the rules in
this paragraph);



          (vii) notwithstanding the foregoing, subject to paragraph (v) of the
definition of Reorganization Taxes in the Tax Reimbursement Agreement, Loss
Attributes, determined separately for each Business in accordance with the other
principles of this Section 3.01, carried over (other than from a Post-Drop-down
Taxable Period) to, or incurred in, a Pre-Drop-down Taxable Period, shall be
considered as Tax Items primarily related to the Stream Business, the MMI
Business and the CST Business, as the case may be, to the extent necessary to
eliminate or reduce Taxes related to the Stream Business, the MMI Business and
the CST Business, respectively, for such taxable year or period, with any excess
Loss Attributes being allocated among the Stream Business, the MMI Business and
the CST Business in proportion to the amount of Taxes that, absent such excess
Loss Attributes, would have been paid by each of Stream, MMI Holdings and CST
Holdings, respectively, in respect of such period. Schedule 3.01(d)(vii) to this
Agreement (and Annex A to the



                                      -10-

provided in this Agreement, Stream shall pay, on a timely basis, all Taxes due

Holdings on behalf of the CST Group hereby assumes and agrees to pay (to the
extent not previously paid by MMI Holdings or CST Holdings or any member of
their respective Groups, as the case may be) the MMI Group's share and the CST
Group's share, as the case may be, of those Taxes (with each share determined as
described below) for all Pre-Drop-down Taxable Periods, which payments shall be
made directly to Stream which shall then forward any balance due to the IRS.



          The share of the consolidated federal Income Tax liability for each of
such periods for the Stream Group, the MMI Group, and the CST Group shall be
determined based on the liability of Stream, MMI Holdings and CST Holdings,
respectively, in respect of such Tax liability in accordance with the principles

that either MMI Holdings or CST Holdings has either overpaid or underpaid its
share (determined as described above) of the consolidated federal income Tax
liability for any period, then not later than 90 days after the filing of
Stream's consolidated federal income Tax returns for such period Stream shall
pay MMI Holdings or CST Holdings, as the case may be, the amount of any such
overpayment, or MMI Holdings or CST Holdings, as the case may be, shall pay
Stream the amount of any such underpayment.

beginning on or before the Drop-down Date with respect to CST and MMI Joint Tax
Returns ("Combined Taxes"). Each of MMI Holdings and CST Holdings hereby assumes
and agrees to pay (to the extent not previously paid by it) the MMI Group's
share and the



                                      -11-

<PAGE>

CST Group's share, as the case may be, of Combined Taxes (with each share
described below) for all Pre-Drop-down Taxable Periods, which payments shall be
made to Stream, which shall then pay any amount due to the appropriate taxing
authority.



          The share of the Combined Tax liability for each of such taxable years
or periods for the Stream Group, the MMI Group, and the CST Group shall be
determined based on the liability of Stream, MMI Holdings and CST Holdings,
respectively, in respect of such Tax liability in accordance with the principles
set forth in Section 3.01.



          If the calculations made pursuant to this Section 3.02(b) indicate
that either MMI Holdings or CST Holdings has either overpaid or underpaid its
share (determined as described above) of the Combined Tax liability for any
period then at such time as Stream shall reasonably determine, but in any event
not later than 90 days after the filing of the relevant Tax Return, Stream shall
pay MMI Holdings or CST Holdings, as the case may be, the amount of any such
overpayment, or MMI Holdings or CST Holdings, as the case may be, shall pay
Stream the amount of any such underpayment.

with the Reorganization to the extent that such assets are located immediately
following the Drop-down Date in a member of the Stream Group, a member of the
MMI Group or a member of the CST Group, respectively, notwithstanding the fact
that the tax laws of the particular jurisdiction may impose liability for such
Transaction Taxes on a member of any other Group. Any party not responsible

     Section 3.03 Redetermined Tax Liabilities.
                  ----------------------------



          (a) Certain Joint Tax Returns. In the case of any Final Determination
              -------------------------
regarding a CST Joint Tax Return or an MMI Joint Tax Return, any Tax Deficiency
shall be paid to the appropriate taxing authority by, and any Tax Refund
received from the appropriate taxing authority shall be paid to, Stream;
provided, however, that whether or not there is a Tax Deficiency or Tax Refund
--------  -------
or whether or not a payment is required to or from the appropriate taxing
authority, MMI Holdings or CST Holdings, as the case may be shall make payments
to Stream or receive payments from Stream based upon the following principles:



          (i) MMI Holdings or CST Holdings, as the case may be, shall make a
payment to Stream in an amount equal to any increase in the MMI Group's or the
CST Group's share, respectively, of Tax with respect to such Joint Tax Return
resulting from such Final Determination to the extent such payments would not be
duplicative of any payments therefor previously made by MMI Holdings (or any
member of the MMI Group) or CST Holdings (or any member of the CST Group) to
Stream (or directly to the appropriate taxing authority). The amount of any such
increase in the MMI Group's or the CST Group's share of Tax shall be determined
in accordance with the principles set forth in Section 3.01.



          (ii) Stream shall pay to MMI Holdings or CST Holdings, to the extent
not previously paid to MMI Holdings or CST Holdings, or any member of their
respective Groups, by the appropriate taxing authority or by Stream, the amount

Tax with respect to such Joint Tax Return resulting from such Final
Determination. The amount of any such decrease in the MMI Group's or the CST
Group's share of Tax shall be determined in accordance with the principles set
forth in Section 3.01.



          (iii) Notwithstanding any provision of this Agreement to the contrary,
for purposes of this Section 3.03(a), Stream shall pay to MMI Holdings and CST
Holdings 40% and 60%, respectively, of the federal Tax Refund for the taxable
year ended December 31, 1993 in respect of a carryback from the taxable year
ended April 21, 1995 in respect of Form 1120X filed by Stream in September,
1996, and 40% and 60%, respectively, of any federal or state overpayments of
Taxes in respect of any Pre-Drop-down Taxable Periods, and any Tax Deficiency
resulting from any subsequent adjustment to Tax Items which gave rise to such
Tax Refund or overpayments shall, to the extent of such Tax Refund and
overpayments, respectively, be borne by such parties in the same proportions.



                                      -13-

<PAGE>

          (iv) Any Tax Deficiency or Tax Refund with respect to (i) a Tax Item
not primarily related either to the Stream Business, the MMI Business or the CST
Business, or (ii) a CST Joint Tax Return or an MMI Joint Tax Return not arising
from an adjustment to, or change in, a Tax Item (e.g., change in applicable law)
shall be allocated 40% to MMI Holdings and 60% to CST Holdings.



          (b) Other Returns. In the case of any Final Determination regarding a
              -------------
Tax Return other than a Joint Tax Return described in Section 3.03(a):



          (i) MMI Holdings (or a member of the MMI Group) shall pay any Tax
Deficiency to the appropriate taxing authority, and shall be entitled to receive
and retain all Tax Refunds, for all periods with respect to Tax Returns that
include only Tax Items primarily related to the MMI Business in accordance with
the principles set forth in Section 3.01.



          (ii) CST Holdings (or a member of the CST Group) shall pay any Tax
Deficiency to the appropriate taxing authority, and shall be entitled to receive
and retain all Tax Refunds, for all periods with respect to Tax Returns that
include only Tax Items primarily related to the CST Business in accordance with
the principles set forth in Section 3.01.



          (iii) Stream shall pay any Tax Deficiency to the appropriate taxing
authority, and shall be entitled to receive and retain all Tax Refunds, for all
periods with respect to Tax Returns that include Tax Items primarily related to
the Stream Business in accordance with the principles set forth in Section 3.01.



          (iv) Any Tax Deficiency or Tax Refund with respect to other Tax
Returns shall be paid by, or shall be received and retained by, the parties in
accordance with the principles set forth in Section 3.01.



          (c) Calculation and Payment of Amounts. All calculations and
              ----------------------------------
determinations required to be made pursuant to this Section 3.03 shall be made
jointly by the parties hereto in good faith or, if necessary, pursuant to
Section 5.04 and on a basis reasonably consistent with prior years. Any payments
made by the parties hereunder to each other shall be treated by each of the
parties, to the maximum extent allowable under applicable Tax laws, as
adjustments to amounts transferred under the Contribution Agreements. The amount
of each payment shall be computed after taking into account all Tax consequences
to the recipient, 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 recipient, or any Affiliate, for purposes of this Section 3.03(c), 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



                                      -14-

<PAGE>

the taxable years or periods in which the recipient, 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.



     Section 3.04 Liability for Taxes with Respect to Post-Drop-down Periods.
                  ----------------------------------------------------------
Unless otherwise provided in this Agreement, or the Tax Reimbursement Agreement,
the Stream Group shall pay all Taxes and shall be entitled to receive and retain
all Tax Refunds with respect to Post-Drop-down Taxable Periods which are
attributable to the Stream Business. Unless otherwise provided in this
Agreement, or the Tax Reimbursement Agreement, each of the MMI Group and the CST
Group, as the case may be, shall pay all Taxes and shall be entitled to receive
and retain all refunds of Taxes with respect Post-Drop-down Taxable Periods
which are attributable to the MMI Business and the CST Business, respectively.
For purposes of this Section 3.04, each Straddle Period shall be treated as
described in Section 3.01.



     Section 3.05 Carrybacks. Each of MMI Holdings and CST Holdings agrees that
                  ----------
it will not carry back any Tax Item arising after the Drop-down Date to a
taxable period with respect to a Joint Tax Return which includes a member of the
Stream Group or the other Group of which it is not a member, without the consent
of Stream and the common parent of the other Group. In the event that MMI
Holdings and CST Holdings do carry back any such Tax Item with the consent of
Stream and the common parent of the other Group, any Tax Refund resulting
therefrom shall be paid over to MMI Holdings or CST Holdings, as the case may
be. To the extent that the carryback of any Tax Item does not result in a Tax
Refund (or would not result in a refund if a claim were filed) solely as the
result of an offsetting Tax Item attributable to another Group, such other Group
shall remit to MMI Holdings or CST Holdings, as the case may be, the amount of
any decrease in the MMI Group's or the CST Group's share of Tax with respect to
such return as a result of such carryback as determined under the principles
contained in Section 3.01 and 3.03(a).



     Section 3.06 Responsibility for Reorganization Taxes. Stream shall be
                  ---------------------------------------
responsible for 100% of any Reorganization Taxes, and shall indemnify, defend
and hold harmless MMI Holdings, CST Holdings and each member of their respective
Groups from and against all liability for such Reorganization Taxes.

     Section 4.01 Breach. Stream shall be liable for and shall indemnify, defend
                  ------
and hold harmless each member of the MMI Group and each member of the CST Group
and their officers and directors, from and against, any payment required to be

indemnify, defend and hold harmless each member of the Stream Group and each
member of the MMI Group and their officers and directors, from and against, any

Group of any obligation under this Agreement.



     Section 4.02 Contest Rights
                  --------------



          (a) Notice. Whenever a party hereto or any Affiliate thereof (the
              ------
"Notified Party") becomes aware of any audit, action, suit, investigation,
claim, assessment, litigation or other administrative or judicial proceeding
(collectively, a "Proceeding") that could result in a redetermination or other
adjustment to any Tax Item which could increase its liability or the liability
of any member of any Group (such party or any such member, hereinafter an
"Indemnitee") for any Tax for which another party hereto (hereinafter the
"Indemnitor") is or may be liable under this Agreement (hereinafter an
"Indemnity Issue"), the Notified Party shall promptly give notice to each other
party hereto of such Indemnity Issue. The failure of any Notified Party to give
such notice shall not relieve the Indemnitor of its obligations under this
Agreement except to the extent such Indemnitor or any of its Affiliates is
actually prejudiced by such failure to give notice.



          (b) General Control Rights. Subject to the other provisions of this
              ----------------------
Section 4.02, with respect to any Proceeding in respect of a Tax Return
relating, in whole or in part, to an Indemnity Issue, the party who has
responsibility for filing such Tax Return (the "Responsible Party") shall have
the right to decide as between the parties hereto how such Proceeding is to be
dealt with and finally resolved with the appropriate taxing authority and shall
control all related Proceedings; provided, however, that if the Responsible
                                 --------  -------
Party is not the Indemnitor, the Responsible Party shall:



                                      -16-

<PAGE>

          (i) promptly deliver to the Indemnitor complete copies of all written
notices, requests, or other information received from any taxing authority or
judicial or similar body that relate to any Indemnity Issue;



          (ii) not provide any documents or other information to any taxing
authority or judicial or similar body that relate to the Indemnity Issue without
the Indemnitor's prior review;



          (iii) not submit any written response or other written work in respect
of any Indemnity Issue to any taxing authority or judicial or similar body
without allowing the Indemnitor to review and revise such written response or
other written work to the extent it relates to any Indemnity Issue (with any
disagreement as to the ultimate language used in any such written response or
other written work to be resolved by the Responsible Party);



          (iv) permit the Indemnitor and its representatives, at the
Indemnitor's sole expense, to participate fully in all conferences, meetings,
proceedings or judicial appearances with or before any taxing authority or
judicial or similar body (whether in person or by telephone) the subject matter
of which is or includes the Indemnity Issue;



          (v) consult in good faith with the Indemnitor with respect to all
aspects of any action or position to be taken by the Responsible Party that
relates to any Indemnity Issue and take the Indemnitor's interests into account;



          (vi) not adopt any position in any Proceeding that unfairly
compromises an Indemnity Issue so as to gain any advantage with respect to any
non-Indemnity Issue which is the subject of the same or any related Proceeding;



          (vii) if the Proceeding relates solely to one or more Indemnity
Issues, permit the Indemnitor to control such Proceeding in all respects; and



          (viii) except in the circumstances described below, not make any
settlement offer to any taxing authority, discuss any settlement offer made by
any taxing authority, or accept any settlement offer made by any taxing
authority, in each case with respect to any Proceeding that is related, in whole
or in part, to any Indemnity Issue.



          (c) Settlements. With respect to any settlement offer that relates, in
              -----------
whole or in part, to any Indemnity Issue, the following rules shall apply if the
Responsible Party is not the Indemnitor:



                                      -17-

<PAGE>

          (i) no settlement offer shall be made by the Responsible Party to any
taxing authority except in writing and in such case the amount offered with
respect to any Indemnity Issue shall be determined solely by the Indemnitor (as
indicated in a written notice to the Responsible Party);



          (ii) in the case of any settlement offer from a taxing authority that
is not in response to a written settlement offer by the Responsible Party, the
Responsible Party shall, if requested by the Indemnitor, make a written
settlement offer (i.e., a counter offer) to the taxing authority in accordance
                  ----
with paragraph (c)(i); and



          (iii) in the case of any settlement offer from a taxing authority
(other than a settlement offer described in paragraph (c)(ii)):



          (A) the Responsible Party may make a written settlement offer (i.e., a
                                                                         ----
counter offer) to the taxing authority in accordance with paragraph (c)(i);



          (B) the Responsible Party may choose not to accept the settlement
offer from the taxing authority and instead choose to litigate the issues
reflected in such settlement offer, in which case the Responsible Party shall
litigate the Indemnity Issue, which litigation shall be conducted subject to the
rules of subsection (b) of this Section 4.02;



          (C) the Responsible Party may notify the Indemnitor of the Responsible
Party's proposal that such settlement offer be accepted and entered into and
request the Indemnitor's consent to doing so and, upon (x) the written consent
to such settlement offer by the Indemnitor, (y) a failure of the Indemnitor to
respond to such proposal by the Responsible Party within thirty days after
receipt by the Indemnitor of such notice from the Responsible Party, or (z) a
failure of the Indemnitor to withhold its consent to such settlement offer in
accordance with subparagraph (D) below, the Responsible Party may accept and
enter into such settlement offer; or



          (D) the Indemnitor may withhold its consent to a settlement offer of
which the Responsible Party has notified the Indemnitor in accordance with
subparagraph (C) above if the Indemnitor (x) notifies the Responsible Party in
writing within such 30-day period that the Indemnitor does not consent to the
proposed settlement, and (y) provides the Responsible Party with an opinion from
tax counsel selected by the Indemnitor and reasonably satisfactory to the
Responsible Party to the effect that there is a reasonable possibility that the
Responsible Party will prevail on the merits with respect to one or more
Indemnity Issues with an aggregate value of not less than the lesser of $1
million or 25% of the



                                      -18-

<PAGE>

amount at issue with respect to the Indemnitor in a tribunal with jurisdiction
to adjudicate the Indemnity Issues;



          (E) if the Indemnitor provides the Responsible Party with written
notification withholding consent in accordance with subparagraph (D) above,
then:



          (i) the Indemnitor shall fully indemnify and hold harmless the
Responsible Party from and against any and all liabilities (other than liability
for payments to the Indemnitor hereunder) for Taxes and other costs and expenses
(including, without limitation, additional attorneys' and accountants' fees)
over and above the payments that the Responsible Party would have been liable
for if the Responsible Party had entered into the proposed settlement; and



          (ii) the Responsible Party shall select one of the following
alternatives:



          (1) the Responsible party shall enter into a closing agreement or
other final resolution with the relevant taxing authority with respect to all
issues in accordance with the proposed settlement other than Indemnity Issues
(if doing so would not preclude litigation or other judicial proceedings with
respect to the Indemnity Issues), provided that (i) such closing agreement or
                                  --------
other final resolution specifically provides that it does not apply to the
Indemnity Issues, and (ii) the Responsible Party agrees to give the Indemnitor
and its representatives control over the relevant Proceedings, and the
Responsible Party further agrees (y) to take such actions requested by
Indemnitor or its representatives to continue to contest (or, if permitted by
applicable law, to permit the Indemnitor to contest) the Indemnity Issues
(through administrative proceedings or litigation, which proceedings or
litigation shall be conducted pursuant to the provisions of this Section 4.02
using counsel selected by the Indemnitor to the fullest extent possible), and
(z) to permit the Indemnitor, if successful, to obtain the full monetary benefit
of a successful contest;



          (2) the Responsible Party shall settle all issues with the relevant
taxing authority in accordance with the proposed settlement, in which case each
of the Responsible Party and the Indemnitor shall, with respect to its share
thereof, pay any additional liability for Taxes as provided for in such proposed
settlement, provided that (i) such settlement shall specifically provide that it
            --------
shall not preclude a refund claim from being filed with respect to the Indemnity
Issues and (ii) the Responsible Party agrees to give the Indemnitor and its
representatives control over the relevant Proceedings, and agrees (y) to take
such actions requested by the Indemnitor to continue to contest (or, if
permitted by applicable law, to permit the Indemnitor to contest) the Indemnity
Issues (through administrative proceedings or



                                      -19-

<PAGE>

litigation, which proceedings or litigation shall be conducted pursuant to the
provisions of this Section 4.02, using counsel selected by the Indemnitor to the
fullest extent possible) and (z) to permit the Indemnitor, if successful, to
obtain the full monetary benefit of such claim for refund, taking into account
any payments to be made under Section 3.03; or



          (3) the Responsible Party shall pay to the Indemnitor, deposit with
the taxing authority, or deposit in escrow any additional liability for Taxes,
interest and penalties as provided for in such settlement to the extent that
such liability relates to issues other than Indemnity Issues, and the
Responsible Party agrees to give the Indemnitor and its representatives control
over the relevant Proceedings, and further agrees (y) to take such actions
requested by the Indemnitor or its representatives to continue to contest (or,
if permitted by applicable law, to permit the Indemnitor to contest) any
Indemnity and non-Indemnity Issues (through administrative proceedings or
litigation, which proceedings or litigation shall be conducted pursuant to the
provisions of this Section 4.02, using counsel selected by the Indemnitor to the
fullest extent possible) and (z) to permit the Indemnitor, if successful, to
obtain the full monetary benefit of a successful contest.



          (d) Payments to Stop Interest. An Indemnitor may, at its election, pay
              -------------------------
to or deposit with the relevant taxing authority an amount of additional Tax for
which the Indemnitor would be liable hereunder if such payment or deposit would
have the effect of stopping the accrual of interest with respect to such Tax
liability. The Indemnitor shall have no further responsibility hereunder for
interest with respect to any amount so deposited or paid for so long as such
deposit or payment stops the accrual of interest; provided, however, that any
                                                  --------  -------
such payment or deposit does not affect any right of the Responsible Party or
any other liability of the Indemnitor hereunder. The Responsible Party shall pay
to the Indemnitor the amount of any Tax received by (or credited to the account
of) the Indemnitee as a result of a determination that such payment or deposit
resulted in an overpayment of Tax with respect to the Indemnity Issues.



          (e) Termination. Notwithstanding the foregoing provisions of this
              -----------
Section 4.02, the Indemnitee in its sole discretion by written notice to the
Indemnitor and the Responsible Party may refrain from contesting (through
administrative or judicial proceedings) any Indemnity Issue or may settle and
instruct the Responsible Party to settle any Indemnitee Issue with the relevant
Taxing authority without the consent of the Indemnitor, in which event each of
the Responsible Party and the Indemnitee shall be deemed to have unconditionally
waived its rights to indemnity with respect to such Indemnity Issue (and other
Indemnity Issues which are related to the Indemnity Issue which the Responsible
Party or Indemnitee refrained from contesting or settled pursuant to this
subsection (e)), In such event, the Responsible Party shall, within ten days
after the Indemnitee has decided to refrain from or settle



                                      -20-

<PAGE>

such contest, reimburse the Indemnitor for all amounts previously advanced,
deposited or paid to the Responsible Party, Indemnitee or any taxing authority
(or deposited pursuant to the provisions of subsection (d) of this Section 4.02)
with respect to such Indemnity Issue (and other Indemnity Issues which are
related to the Indemnity Issue which the Responsible Party or Indemnitee has
refrained from contesting or settled pursuant to this subsection (e)), other
than third-party expenses incurred by the Responsible Party or Indemnitee in
contesting the Indemnity Issue, together with interest at the rate for
underpayment of tax determined pursuant to Section 6621(a)(2) of the Code in
effect from time to time, from the date of payment to the date of reimbursement.



          (f) The rights of the parties under this Section 4.02 shall be subject
to the rights of RRD under Section 7 of the Tax Reimbursement Agreement.

frequently than monthly) as requested by Stream to discuss the status of the
preparation of the information set forth in clauses (i) and (ii) of this Section
4.03(a). If, as a result of any such meeting, Stream reasonably determines that
it is likely that MMI Holdings or CST Holdings will not be able to perform its
obligations under this Section 4.03(a) in a timely manner, then Stream shall
have the right to engage a certified public accounting firm of its choice to
gather such information and the MMI Group or the CST Group, as the case may be,
shall permit any such accounting firm full access to all appropriate records or
other information in its possession. The expenses of such accounting firm shall
be borne equally by Stream and MMI Holdings or CST Holdings, as the case may be.

other determinations by taxing authorities, including without limitation,
foreign taxing authorities, and records concerning the ownership and Tax basis
of property, which a party may possess; and the issuing corporation's providing
information to the employer corporation with respect to the exercise of
compensatory options to acquire stock of the issuing corporation by an
optionholder who was not an employee of the issuing corporation, including the
optionholder's name, social security number and address, the exercise date, the
exercise price, the fair market value and the number of shares issued, and such
other information as the employer corporation may reasonably request. Each party
shall make its employees and facilities available on a mutually convenient basis
to provide explanations of any documents or information provided hereunder.



          (c) MMI Holdings, CST Holdings and Stream agree to retain all Tax
Returns, related schedules and workpapers, and all material records and other
documents as required under Section 6001 of the Code and the regulations

period, then the requesting party shall have the right to engage a certified
public accounting firm of its choice to gather such information. Stream, MMI
Holdings and CST Holdings, as the case may be, agree upon 24 hours' notice, in
the case of a failure to provide information pursuant to subsection (a) hereof,
and otherwise upon 30 days' notice after the expiration of such reasonable
period, to permit any such accounting firm full access to all appropriate
records or other information in the possession of any member of the Stream
Group, the MMI Group or the CST Group, as the case may be, during reasonable
business hours, and to reimburse or pay directly all costs and expenses in
connection with the engagement of such public accountants.



          (e) If any member of the Stream Group, the MMI Group or the CST Group,
as the case may be, supplies information to a non-member of the Stream Group,
MMI Group or CST Group, as the case may be, pursuant to this Section 4.03 and an
officer of the requesting party signs a statement or other document under
penalties of perjury in reliance upon the accuracy of such information, then a
duly authorized officer of the party supplying such information shall certify,
under penalties of perjury, the accuracy and completeness of the information so
supplied. Stream agrees to indemnify and hold harmless each member of the MMI
Group and the CST Group and its directors, officers and employees, from and
against any cost, fine, penalty or other expense of any kind attributable to the
negligence or willful misconduct of a member of the Stream Group, in supplying a

harmless each member of the Stream Group and the CST Group or the MMI Group, as

any cost, fine, penalty or other expense of any kind attributable to the
negligence or willful misconduct of a member of the MMI Group or the CST Group,
as the case may be, in supplying a member of the Stream Group or the other Group
with inaccurate or incomplete information.



     Section 4.04 Injunction. The parties hereto agree that the payment of
                  ----------
monetary compensation would not be an adequate remedy to a breach of the
obligations contained in Section 4.03 hereof, and each party consents to the
issuance and entry of an injunction against the taking of any action by it or a
member of its Group described in the preceding section.
