                 Minimum Performance Standard Event in a calendar month of the
                 Term, the amount specified as such in this Schedule B for the
                 corresponding Minimum Performance Standard.

          (ff)   "Postal Day" means U.S. Postal Service workdays. Where this
                 Schedule B provides for the addition or subtraction of a Postal
                 Day(s), the result will mean the same time of day as the time
                 of an event on the original Postal Day (i.e., if the completion
                 time for a Print and Insertion Job is scheduled for 3:00 p.m.
                 on Monday and is extended by one (1) Postal Day, the resulting
                 completion time is 3:00 p.m. local time on Tuesday, provided
                 that both Monday and Tuesday are Postal Days).

          (gg)   "Print Productivity" means, with respect to a Print Only Job or
                 a Print and Insertion Job, the time between the moment of
                 receipt by IBM from a MSDW Business Unit of the necessary data
                 files that such MSDW Business Unit is responsible for providing
                 IBM in conjunction with such Print Only Job or Print and
                 Insertion Job, and (i) if the job is a Print Only Job, the time
                 that the aggregate printed output associated with such Print
                 Only Job is printed and tendered for pick-up or delivery, as
                 appropriate, to the appropriate MSDW vendor responsible for
                 mailing such printed output, or (ii) if the job is a Print and
                 Insertion Job, the time that all Mailers associated with that
                 Print and Insertion Job are prepared for mailing (i.e.,
                 printed, inserted and postmarked), delivered to the IBM presort
                 vendor and delivered to the U.S. Postal Service.

          (hh)   "Print and Insertion Job" means (i) the printing, processing,
                 organizing, inserting and preparation for mailing of the
                 printed and other materials that are specified in the
                 Attachments to this Schedule B, and (ii) the mailing of such
                 materials to MSDW customers or the delivery of such materials
                 to the appropriate IBM vendor responsible for mailing such

                 organizing, that prepares such items for pickup by the
                 appropriate MSDW vendor or delivery to the appropriate
                 destination of such MSDW vendor responsible for mailing such
                 items.

          (jj)   "Problem" means (i) any user question or concern regarding the
                 Services, or (ii) any unscheduled event that adversely affects
                 the Services. Upon notification of a Problem to a Help Desk,
                 IBM shall identify and classify such Problem according to the
                 Severity Levels; however, MSDW may reasonably and in good faith
                 change the Severity Level selected by IBM to more accurately

2.    OVERVIEW OF PERFORMANCE STANDARDS

      2.1    Rights and Remedies.
             -------------------

             Except to the extent that { * } of this Schedule B, { * } relating
             to a failure to perform the Services.

      2.2    Overview of Performance Standards.
             ---------------------------------

             The Performance Standards consist of the following sets of metrics:

             (a)   Business Delivery Standards. This Schedule B, including the
                   ---------------------------
                   Attachments, set forth certain obligations regarding IBM's
                   performance of the Services which reflect IBM's performance
                   of the Services historically (such Performance Standards the
                   "Business Delivery Standards"). MSDW and IBM each acknowledge
                   that the agreed-upon Business Delivery Standards largely
                   reflect an average over a year of monthly performance
                   results, with some individual months' results for a given
                   Business Delivery Standard falling above the agreed Business
                   Delivery Standard and some falling below. Inherently, then,
                   there will continue to be a range of monthly Business
                   Delivery Standard results, some above and some below the
                   corresponding Business Delivery Standard. See Article 3 below
                   for the handling of Business Delivery Standard Events.

             (b)   Minimum Performance Standards. This Schedule B, including the
                   -----------------------------
                   Attachments, set forth certain contractual obligations
                   regarding IBM's performance of the Services that if not
                   achieved or exceeded by IBM may have a significant, adverse
                   impact on MSDW or its business (the "Minimum Performance
                   Standards"). See Article 4 below for the handling of Minimum
                   Performance Standard Events.

             Attachments B-1 through B-3 of this Schedule B each set forth the
             Performance Standards applicable to particular MSDW Business Units,
             and Attachment B-4 of this Schedule B sets forth Performance
             Standards for Voice Services applicable to all MSDW Business Units.

3.    BUSINESS DELIVERY STANDARD EVENTS

      The Parties have created Business Delivery Standards which represent IBM's
      historical performance. The Parties will use these Business Delivery
      Standards as a basis to measure IBM's commitment under the first sentence
      of Section 8.1 of the Agreement. If IBM's performance fails to achieve a
      Business Delivery Standard (a "Business Delivery Standard Event"), IBM
      will analyze the failure and take appropriate remedial steps to rectify
      the underlying problem(s). As appropriate, IBM will determine the cause of
      a Business Delivery Standard Event. Resolution of a problem may result in
      additional technology investment by IBM or MSDW, changes in operations,
      procedures or Performance Standards, changes in system or applications
      software or other factors. MSDW approval for such resolution will be
      required to the extent that such resolution involves (a) additional
      charges to MSDW, (b) any change in MSDW operations, MSDW procedures, or
      MSDW Software, (c) any change in the scope or

<PAGE>

      delivery of Services, (d) any change to the Performance Standards, or (e)
      any other change to the terms of the Agreement. MSDW acknowledges that the
      time frame for IBM to analyze and resolve Business Delivery Standard
      Events may vary depending on the nature and extent of the underlying
      problem(s), and IBM agrees to exercise diligence in diagnosing and
      remedying the underlying problem(s). Where the resolution to a Business
      Delivery Standard Event requires MSDW agreement as described in this
      Article, IBM will communicate its proposed remediation plan to MSDW and
      obtain MSDW's agreement before proceeding.

4.    MINIMUM PERFORMANCE STANDARD EVENTS

      4.1    Minimum Performance Standards.
             -----------------------------

             IBM agrees that its performance of the Services will meet or exceed
             each of the Minimum Performance Standards.

      4.2    Minimum Performance Standard Event.
             ----------------------------------

             If IBM fails to achieve a Minimum Performance Standard (a "Minimum
             Performance Standard Event"), IBM will, at no additional charge to
             MSDW: (a) promptly and fully report to MSDW the relevant
             circumstances and causes of such failure that are known initially;
             (b) promptly undertake an appropriate causal analysis to determine
             and diagnose the problem(s) causing the failure and to identify the
             necessary remedial measures to be taken to rectify the problem(s)
             so it does not continue or reoccur, promptly notifying any affected
             MSDW Business Unit(s) of its determinations in these regards; (c)
             promptly pursue and implement remedial measures, applying such new
             or additional resources or services as are reasonably required in
             order to rectify the underlying problem(s); and (d) { * } pursuant
             to Section 8.2(b) of the Agreement, pay the applicable Performance
             Standard Credit as computed pursuant to this Article 4.

      4.3    Performance Standard Credits.
             ----------------------------

             (a)  If more than one such Minimum Performance Standard Event
                  occurs in a single calendar month, the sum of the
                  corresponding Performance Standard Credits shall be credited
                  to MSDW { * } pursuant to Section 8.2(b) of the Agreement.

             (b)  In no event shall the total amount of Performance Standard
                  Credits credited to MSDW with respect to Minimum Performance
                  Standard Events occurring in a calendar month exceed, in the
                  aggregate, the Amount at Risk for such calendar month.

      4.4    Assessment of Performance Standard Credits.
             ------------------------------------------

             (a)  In the event of a Minimum Performance Standard Event, IBM
                  shall credit to MSDW pursuant to Subsection (e) of this
                  Section an amount (the "Credit Equivalent") equal to the
                  applicable Performance Standard Credit on the monthly invoice
                  rendered by IBM during the month immediately following the
                  month in which the corresponding Minimum Performance Standard
                  Event was reported to MSDW or the applicable MSDW Business
                  Unit(s); or, if IBM is not obligated to prepare a monthly
                  invoice for MSDW for the month immediately

<PAGE>

                    following the month in which the corresponding Minimum
                    Performance Standard Event was reported, IBM shall pay such
                    Credit Equivalent to MSDW within { * } of the end of the
                    calendar month in which the corresponding Minimum
                    Performance Standard Event was reported to MSDW or the
                    applicable MSDW Business Unit(s). Notwithstanding the
                    foregoing, IBM's crediting of the Credit Equivalent pursuant
                    to this Subsection (a) shall not { * } to receive the
                    applicable Performance Standard Credit { * } under the
                    Agreement.

             (b)    At any time within { * } after the occurrence of a Minimum
                    Performance Standard Event, { * } corresponding to such
                    Minimum Performance Standard Event { * }. { * } shall not {
                    * } to receive the applicable Performance Standard Credit {
                    * } under the Agreement.

             (c)    If, after { * } after the occurrence of a Minimum
                    Performance Standard Event, { * } corresponding to such
                    Minimum Performance Standard Event, then MSDW shall { * },
                    and MSDW's { * } Credit Equivalent shall { * }, the Minimum
                    Performance Standard Credit for the Minimum Performance
                    Standard Event corresponding to such Credit Equivalent.

             (d)    Subject to Subsection (c) of this Section, if at any time
                    within { * } subsequent to the reporting by IBM to MSDW of a
                    Minimum Performance Standard Event MSDW { * }, pursuant to
                    Section 8.2(b) of the Agreement, the corresponding
                    Performance Standard Credit, then IBM { * } applicable at
                    the time of the Minimum Performance Standard Event less any
                    Credit Equivalent corresponding to the same Minimum
                    Performance Standard Event, pursuant to Subsection (e) of
                    this Section, in the { * } after MSDW notifies the IBM
                    Project Executive of { * }; or if IBM is not obligated to
                    prepare a monthly invoice, { * } following the month in
                    which MSDW notifies IBM's Project Executive of { * }, IBM
                    will pay such Performance Standard Credit to MSDW { * } of
                    the end of the calendar month in which such notice was
                    given. Any Performance Standard Credits not paid by IBM
                    within the time specified above shall bear interest at the
                    rate specified in Section 13.2(c) of the Agreement.

             (e)    Reports including Credit Equivalents or Performance Standard
                    Credits will separately itemize each Credit Equivalent and
                    Performance Standard Credit and identify them as such,
                    briefly describing the Minimum Performance Standard Event
                    corresponding to each Credit Equivalent or Performance
                    Standard Credit and identifying the applicable MSDW Business
                    Unit (or designating MSDW if such Credit Equivalent or
                    Performance Standard Credit corresponds to an
                    enterprise-wide Minimum Performance Standard set forth in
                    Article 6 of this Schedule B). IBM may net the Credit
                    Equivalents and Performance Standard Credits in an invoice.

5.    ADJUSTMENT OF PERFORMANCE STANDARDS

      5.1    Review of Performance Standards.

                      (iv)   changes in regulatory or audit requirements
                             affecting MSDW or an MSDW Business Unit;

                      (v)    material changes in, or the evolution or
                             elimination of, technology used to provide the
                             Services, such as the retirement of old processes
                             (including the transition by a MSDW Business Unit
                             to new data network connectivity such as frame
                             relay), system enhancements, operating environment
                             changes, and improvements in technology;

                      (vi)   any repeated failure by MSDW or IBM to deliver
                             those Services for which no Performance Standards
                             are specified; and

                      (vii)  any other event or events agreed upon by the
                             Parties.

        5.2    Proposing Changes to Performance Standards.
               ------------------------------------------

               (a)    Following such review, either Party may propose, pursuant
                      to Subsection (b) of this Section, any adjustments to the
                      then-current Performance Standards, or the addition,
                      deletion or substitution of Performance Standards, that
                      are necessary or appropriate under the circumstances, and
                      which are consistent with the events that caused the
                      Parties to review the Performance Standards pursuant to
                      Section 5.1 of this Schedule B.

               (b)    The Project Executive of the Party proposing such action
                      shall submit to the other Party a written summary of the
                      business or technical case that supports such action,
                      which will include the following:

                      (i)    A detailed description of the proposed action;

                      (ii)   The intended objective or expected benefit; and

                      (iii)  Any reasonably known dependencies upon other
                             Performance Standards or other effects upon or
                             changes to the Performance Standards and the
                             Services.

                  The Party receiving a proposed change to the Performance
                  Standards will expeditiously review and approve or reject such
                  proposal. During such review, representatives of the Parties
                  will confer as necessary, answer questions that the receiving
                  Party may have regarding the proposed change, and take such
                  other steps as reasonably necessary. If the Parties agree to
                  make a proposed change to the Performance Standards, they will
                  mutually agree in writing to such change and to corresponding
                  changes to the terms, conditions and additional charges, if
                  any, within a period as is minimally reasonably necessary for
                  the required analysis. Neither Party will { * } a proposal
                  advanced by the other Party for a change in Performance
                  Standards or the particulars of implementing such a change.

                         in Section 9.2 of the Agreement), IBM will provide
                         reporting of MACs Time with respect to its performance
                         of XID MACs, circuit MACs and any other MACs for which
                         the Parties mutually agree that such reporting will be
                         provided by IBM.

                   (b)   In the event that the Parties mutually agree that
                         Performance Standards for MACs Time shall be created,

                         (i)     MACs Time for each type of MAC (e.g., circuit
                                 MACs, XID MACs, VTAM and NCP Software changes,
                                 other mutually agreed-upon MACs) shall be
                                 baselined by IBM for { * } (or as mutually
                                 agreed otherwise) using a mutually agreed-upon
                                 measurement tool and measurement process;

                         (ii)    a MACs Time Business Delivery Standard shall be
                                 established based upon the average of the
                                 monthly performances (measured on a
                                 calendar-month basis) during this { * } period
                                 (or such other mutually agreeable period);
                                 provided, however, that the numerical level
                                 established for such Business Delivery Standard
                                 shall be no less favorable to MSDW than any
                                 corresponding numerical level proposed to MSDW
                                 by IBM { * } terms and conditions of such

                                 the basis for determining a MACs Time Minimum
                                 Performance Standard, the level of which will
                                 be mutually agreed upon by the Parties; and

                     4.2, 4.3 and 4.4 of this Schedule B, if the same event or
                     discrete set of events causes two or more Minimum
                     Performance Standard Events for a single MSDW Business Unit
                     with respect to two or more Minimum Performance Standards

                     Performance Standards would be payable by IBM shall be
                     expressly documented and set forth in this Schedule B.

        7.2   MSDW Business Unit Customer Satisfaction.
              ----------------------------------------

              (a)    Within { * } after the Effective Date or as otherwise
                     mutually agreed by the Parties, IBM shall develop and
                     propose for the approval of the Parties (i) a draft
                     customer satisfaction questionnaire designed to measure,
                     for each MSDW Business Unit that receives Services, the
                     satisfaction of recipients of the Services with IBM's
                     provision of such Services, and (ii) a list identifying a
                     representative, statistically reasonable sampling of those
                     recipients of the Services who will receive such
                     questionnaire as part of the survey process described in
                     Subsection (b) of this Section. Following MSDW's review of
                     the foregoing, IBM shall incorporate reasonable comments or
                     suggestions of MSDW and shall finalize the questionnaire
                     and list within { * } after receiving MSDW's comments and
                     suggestions. The final customer satisfaction questionnaire
                     and list shall be subject to the approval of both Parties.
                     IBM shall periodically update (A) the questionnaire to
                     reflect New Services or changes to existing Services, and
                     (B) the list as necessary to ensure that a reasonable
                     sampling of recipients of the Services (including the
                     sampling size described in (ii) above) is maintained;

                  provided, however, that updates of the questionnaire and list
                  shall be provided to MSDW for review, comment, and approval.

            (b)   Periodically (but in no event less than { * }), IBM will
                  conduct a customer satisfaction survey using the
                  questionnaire and list of recipients described in Subsection
                  (a) of this Section. IBM will tally the results of such
                  survey and report to MSDW the results for each MSDW Business
                  Unit, integrating the results with previous survey results
                  (e.g., performing trend analysis). The Parties will meet to
                  identify the areas of dissatisfaction as such dissatisfaction
                  relates to the Services. IBM will prepare a project plan,
                  with MSDW's input and subject to MSDW's final approval, that
                  specifically addresses the steps IBM will take to correct
                  such dissatisfaction. The project plan will specify the
                  specific remedial steps IBM will take to rectify deficiencies
                  in satisfaction, and the time frames in which IBM will
                  implement those steps.

       7.3  Hours.
            -----

            (a)   Unless otherwise noted, all references to time of day shall
                  refer to Eastern Time ("E.T.").

            (b)   Any reference to "hour" or "hours" shall mean clock hours.

       7.4  Measurement Frequency.
            ---------------------

            Except as otherwise expressly provided in this Schedule B (including
            the Attachments), the Measurement Window for any Performance
            Standard shall be a calendar month.

       7.5  Right of Access to Performance Standard Information.
            ---------------------------------------------------

            Upon MSDW's reasonable request, IBM shall provide, and MSDW will
            have access to, Performance Standards information to the extent
            relevant to MSDW. Examples of this information include MICS extracts
            for jobs; STEP, CICS, DB2, and print data files; SMF data; TMC
            catalog data; read-only INFO access; OMEGAMON for CICS; and OMEGAMON
            for DB2.

       7.6  Multiple Performance Standard Conditions.
            ----------------------------------------

            Unless otherwise expressly agreed, where a Performance Standard
            includes multiple conditions or components (e.g., components (a),
            (b), (c)), satisfaction of each and every condition or component
            (i.e., components (a), (b) and (c)) is necessary for the
            satisfaction of the corresponding Performance Standard.


      7.7   Excused Events.
            --------------

            IBM will be excused from a failure to provide a Service in
            accordance with this Schedule B if and to the extent that:

            (a)   such failure is excused as a Force Majeure Event pursuant to
                  Section 19.3 of the Agreement; or

            (b)   such failure is caused by

                         the extent that such action or omission is not within
                         the scope of those management or other responsibilities
                         that IBM has assumed under the Agreement with respect
                         to such third party vendors

                  that materially adversely affects IBM's ability to perform the
                  Services hereunder or to meet its obligations in a timely
                  manner, and to the extent upon learning of such problem IBM:
                  (i) promptly notifies MSDW of the problem and, if known, the
                  acts or omissions believed to be causing such problem and
                  their ramifications; (ii) promptly takes commercially
                  reasonable steps to mitigate the adverse impact of the acts or
                  omissions on the Services; and (iii) works with MSDW or such
                  third party vendor(s) (if any) diligently and in good faith to
                  avoid, minimize and circumvent such problem or delay to the
                  Services. MSDW, upon learning of any problem which may
                  adversely impact or affect the Services, will: (i) promptly
                  notify IBM of the problem and, if known, of the acts or
                  omissions believed to be causing such problem and their
                  ramifications; (ii) promptly take commercially reasonable
                  steps to mitigate the adverse impact of the acts or omissions
                  on the Services; and (iii) work with IBM and instruct its
                  third party vendor(s) (if any) to work with IBM diligently and
                  in good faith to avoid, minimize and circumvent such problem
                  or delay.

      7.8   Establishment of Performance Standards Applicable to Managed Data
            -----------------------------------------------------------------
            Network Services (MDNS).
            -----------------------

            (a)   No later than November 1, 1999 (or as otherwise mutually
                  agreed upon by the Parties), IBM shall develop and propose,
                  for the review and approval of the Parties, measurement tools
                  and processes that track and report Availability, Latency, and
                  Frame Delivery Rate for Managed Data Network Services
                  ("MDNS"). Following MSDW's review of the proposed tools and
                  processes, IBM shall incorporate reasonable comments or
                  suggestions of MSDW and shall finalize such tools and
                  processes within { * } after receipt of MSDW's comments and
                  suggestions (or as otherwise mutually agreed upon by the
                  Parties). IBM's performance of its obligations described in
                  this Subsection (a) shall constitute a Minimum Performance
                  Standard to which the following Performance Standard Credits
                  shall apply: (i) a Level Three Credit Amount for IBM's initial
                  failure to perform any of such obligations (such failure an
                  "Initial Failure"), plus (ii) a Level Three Credit Amount for
                  each calendar month, elapsing after such Initial Failure, that
                  IBM has not performed the obligation(s) corresponding to such
                  Initial Failure.

            (b)   Upon finalization of such tools and processes within such { *
                  } period, IBM will baseline IBM's performance of Availability,
                  Latency and Frame Delivery Rate with respect to MDNS Data
                  Network Services, for each MSDW Business Unit that receives
                  such Services, for { * } (or other mutually agreeable period)
                  using such measurement tools and processes. An Availability
                  Business Delivery Standard, Latency Business Delivery
                  Standard, and Frame Delivery Rate Business Delivery Standard
                  shall be established, for each MSDW Business Unit that
                  receives MDNS Data Network Services, based upon the average of
                  the

                    monthly performances (measured on a calendar-month basis)
                    applicable to each of such MSDW Business Units during this {

                    provided, however, that the numerical level established for
                    such Business Delivery Standards shall be no less favorable
                    to MSDW than

                    (i)    any corresponding numerical level proposed to MSDW by
                           IBM { * } (e.g., the performance levels provided as
                           part of IBM's Gold Plan for MDNS), { * } terms and
                           conditions of such offering but based upon a
                           reasonable comparison of the architectural
                           differences between (A) the configuration applicable
                           to such numerical level, and (B) the configuration
                           implemented for MSDW; and

                    (ii)   any corresponding contractually committed level of
                           service that IBM receives from any Authorized
                           Subcontractors (as defined in the Agreement) that
                           provide services underlying the MDNS Data Network
                           Services.

                    MSDW and IBM agree that such baselined performances will
                    also serve as the basis for determining an Availability
                    Minimum Performance Standard, Latency Minimum Performance
                    Standard, and Frame Delivery Rate Minimum Performance
                    Standard for each MSDW Business Unit that receives MDNS Data
                    Network Services, the levels of which will be mutually
                    agreed upon by the Parties. MSDW may designate the Credit
                    Amount (i.e., Level One Credit Amount, Level Two Credit
                    Amount, or Level Three Credit Amount) applicable to each of
                    such Minimum Performance Standards { * }.

/1/ The applicable Batch Jobs and their corresponding scheduled completion times
are those listed in Annex B1-2, as such listing may be modified from time to
time by the mutual agreement of the Parties. In the event that the Parties agree
to add one (or more) Batch Job(s) to Table B1-2-1 of Annex B1-2, performance for
the new Batch Job will be baselined for { * } (or such other mutually agreeable
period). Thereafter, the foregoing Batch Completion Time Business Delivery
Standard shall be amended pursuant to the following formula:

                                    N= { * }

where: "N" is the amended Batch Completion Time Business Delivery Standard, "O"
is the prior Batch Completion Time Business Delivery Standard, "B" is the
percentage of Batch Completion Times for the added Batch Job during the
baselining period that are earlier than or equal to the corresponding scheduled
completion time for such added Batch Job(s), "x" is the aggregate number of
scheduled runs for all of the Batch Jobs in Table B1-2-1 of Annex B1-2
(including the added Batch Job(s)), and "y" is the aggregate number of scheduled
runs for the added Batch Job(s).

If a change in the scheduled completion time for a Batch Job is agreed upon by
the Parties, the change will be documented (via e-mail), Table B1-2-1 of Annex
B1-2 shall be deemed modified to the extent of such documented and agreed-upon
change, and the foregoing Batch Completion Time Business Delivery Standard will
remain unchanged. The Parties agree to review and update Annex B1-2 to add or
subtract Batch Jobs or to modify the names or scheduled completion times of the
Batch Jobs and as applicable, update Batch Completion Time Business Delivery
Standard on a { * } basis, or as otherwise mutually agreed upon by the Parties.

/1/ Availability measured on a { * } basis using the { * }, which constantly
updates { * } records. IBM will collect such records, and report, on the
applicable monthly report, { * } Data Network Availability as specified by this
Table B2-1. For the purposes of this Table B2-1 only, "Representative Sample"
means a sample that consists of at least { * } of all DWR physical units ("PUs")
for which IBM is responsible. The PUs included in the Representative Sample will
be reported to DWR in the { * } PU Availability report. IBM will actively
monitor the { * } Data Network and report any Outages in accordance with
practices in place prior to the Effective Date. In the event of an Outage of a
circuit providing primary connectivity to a DWR site such that it is necessary
to activate the { * } feature with respect to such circuit, IBM shall restore
the affected primary circuit as soon as possible. If such Outage exceeds { * }
in duration, then upon DWR's request, IBM will perform a root-cause analysis to
determine the cause(s) for the Outage, and will promptly report any findings to
DWR. Upon receiving notice of an Outage, the appropriate IBM Help Desk shall
promptly open a problem ticket for such Outage and notify DWR of the Outage
within { * } of receiving such notice. If DWR is dissatisfied with the
timeliness of the Help Desk's notification, then upon DWR's request, IBM shall
investigate the cause(s) for any delays, take such action as is reasonably
necessary to ensure that such delays do not recur, and reasonably demonstrate to
DWR that it has performed such investigation and taken such action.

/2/  "High-Volume Site NCPs" shall mean the following { * } key NCPs: { * }. IBM
will measure the Availability of each High-Volume Site NCP.

/3/ Availability will be measured on a { * } basis by the { * }, which polls
each endpoint (i.e., the site router) of the { * } Data Network every { * } and
is reported via { * }. A "dual-attached site" is Available for Use if either of
the two leased lines to the site router is Available for Use. A "site with dial
backup" is Available for Use if the leased line or the switched dial backup
circuit to the site router is Available for Use.

/1/ The applicable Batch Jobs and their corresponding scheduled completion times
are those listed in Annex B2-1, as such listing may be modified from time to
time by the mutual agreement of the Parties. In the event that the Parties agree
to add one (or more) Batch Job(s) to Table B2-1-1 of Annex B2-1, performance for
the new Batch Job will be baselined for { * } (or such other mutually agreeable
period). Thereafter, the foregoing Batch Completion Time Business Delivery
Standard shall be amended pursuant to the following formula:
                                          N= { * }
where: "N" is the amended Batch Completion Time Business Delivery Standard, "O"
is the prior Batch Completion Time Business Delivery Standard, "B" is the
percentage of Batch Completion Times for the added Batch Job during the
baselining period that are earlier than or equal to the corresponding scheduled
completion time for such added Batch Job(s), "x" is the aggregate number of
scheduled runs for all of the Batch Jobs in Table B2-1-1 of Annex B2-1
(including the added Batch Job(s)), and "y" is the aggregate number of scheduled
runs for the added Batch Job(s).

If a change in the scheduled completion time for a Batch Job is agreed upon by
the Parties, the change will be documented (via e-mail), Table B2-1-1 of Annex
B2-1 shall be deemed modified to the extent of such documented and agreed-upon
change, and the foregoing Batch Completion Time Business Delivery Standard will
remain unchanged. The Parties agree to review and update Annex B2-1 to add or
subtract Batch Jobs or to modify the names or scheduled completion times of the
Batch Jobs and as applicable, update Batch Completion Time Business Delivery
Standard on a { * } basis, or as otherwise mutually agreed upon by the Parties.

/1/ The CPU Objective Allocation metric is a host-based measurement expressed in
two variables, "Successful Address Space Threshold" and "Successful Job
Threshold," which are defined in Section 1.2 of Schedule B. Tasks are listed in
descending order of priority for CPU dispatch. The order of priority may be
changed upon the mutual agreement of DWR and IBM. Upon DWR's registering an
application with IBM, IBM will assign the application the Task Classification
mutually agreed upon by DWR and IBM.
/2/ For the purposes of this Table B2-8 only, "Prime" means { * } E.T.;
"Non-Prime" means all times that are not Prime as defined in this footnote. The
Business Delivery Standard for each shift category shall be satisfied if the
sampled Successful Job Thresholds are greater than or equal to the levels of
such variables specified above in the "Successful Job Threshold" column.
/3/ The Successful Job Threshold will be measured using sampling obtained from
each address space on each host { * }, recorded in a record written to storage
media. Samples for tasks of { * } or less shall be excluded.

as of the Effective Date are provided in { * } pages 1945-1946 (Dean Witter
Securities) and 20058-20059 (Year End), as such listings may be amended from
time to time by the mutual agreement of DWR and IBM. If DWR provides the
necessary data to execute the Print and Insertion Job within { * } the
corresponding scheduled Batch Job completion time, then the corresponding
Minimum Performance Standard period and corresponding Business Delivery Standard
period, as applicable, for such Print and Insertion Job will be { * }. If DWR
provides the necessary data to execute the Print and Insertion Job at any time
subsequent to { * } the corresponding scheduled Batch Job completion time, DWR
and IBM will set a mutually agreeable corresponding Minimum Performance Standard
period and corresponding Business Delivery Standard period, as applicable, for
the impacted individual Print and Insertion Job(s).

In the event that IBM provides additional resource capacity or modifies Service
architecture with respect to the print and insertion Services corresponding to
the Print and Insertion Jobs set forth in this Table B2-2-1, then IBM's
performance of the related Services shall be baselined by IBM for { * } (or such
other mutually agreeable period) after the date that such change is implemented.
Each Print and Insertion Quality Business Delivery Standard set forth in
Attachment B-2 shall be adjusted to be equal to the { * } the monthly
performance (measured on a calendar-month basis) during this { * } (or such
other mutually agreeable period) for the corresponding Print and Insertion Job.
Each Print and Insertion Quality Minimum Performance Standard set forth in
Attachment B-2 shall also be adjusted; provided, however, that the proportion
between the adjusted Minimum Performance Standard and the adjusted Business
Delivery Standard is no less favorable to MSDW than the proportion between the
corresponding unadjusted Minimum Peformance Standard and unadjusted Business
Delivery Standard. In no event shall the adjustment described in this footnote
result in any Minimum Performance Standard or Business Delivery Standard less
favorable to MSDW than before such adjustment.

completion time for such added Batch Job(s), "x" is the aggregate number of
scheduled runs for all of the Batch Jobs in Table B3-1-1 of Annex B3-1
(including the added Batch Job(s)), and "y" is the aggregate number of scheduled
runs for the added Batch Job(s).

If a change in the scheduled completion time for a Batch Job is agreed upon by
the Parties, the change will be documented (via e-mail), Table B3-1-1 of Annex
B3-1 shall be deemed modified to the extent of such documented and agreed-upon
change, and the foregoing Batch Completion Time Business Delivery Standard will

listed in the corresponding table in Annex B3-2.
/4/ Discover and IBM agree that CICS subsystems operating in any additional
production regions that are provided by IBM upon the request of Discover will be
deemed to be added to Annex B3-2 and performance for each of these subsystems
will be baselined by IBM for { * } (or such other mutually agreeable period)
after the later of (i) September 1, 1998, and (ii) the date such subsystem is
introduced into a Discover processing environment. A CICS Availability/1/
Business Delivery Standard corresponding to each additional subsystem shall be
determined, as mutually agreed, based upon the { * } each additional subsystem's
monthly performance (measured on a calendar-month basis) during this { * }

such baselined performance for each additional subsystem will also serve as the
basis for determining any corresponding Availability/1/ Minimum Performance
Standard applicable to such subsystem, as mutually agreed.

the foregoing, (a) if the number of individual subsystems for which
Availability/1/ *** { * } per subsystem exceeds { * } but is less than or equal

/1/ The CPU Objective Allocation metric is a host-based measurement expressed in
two variables, "Successful Address Space Threshold" and "Successful Job
Threshold," which are defined in Section 1.2 of Schedule B. Tasks are listed in
descending order of priority for CPU dispatch. The order of priority may be
changed upon the mutual agreement of Discover and IBM. Upon Discover's
registering an application with IBM, IBM will assign the application the Task
Classification mutually agreed upon by Discover and IBM.
/2/ For the purposes of this Table B3-8 only, "Prime" means { * } E.T.;
"Non-Prime" means all times that are not Prime as defined in this footnote. The
Business Delivery Standard for each shift category shall be satisfied if the
sampled Successful Job Thresholds are greater than or equal to the levels of
such variables specified above in the "Successful Job Threshold" column.
/3/ The Successful Job Threshold will be measured using sampling obtained from
each address space on each host { * }, recorded in a record written to storage
media. Samples for tasks of { * } or less shall be excluded.

                      Voice Services Performance Standards


This Attachment B-4 sets forth the Performance Standards applicable to Voice
Services.

1.   DEFINITIONS

     1.1  Certain Definitions.
          -------------------

          As used in this Attachment B-4:

          (a)  "Blocked" means the return of a busy signal to a caller or
               failure to connect a call to the intended recipient on the Voice
               Network that is due to a failure for which IBM is responsible.

          (b)  "Grade of Service" or "GOS" means the probability that a call
               originating from or terminating at MSDW during the applicable
               Measurement Window for a GOS Performance Standard will be
               Blocked. GOS is calculated by dividing (i) the number of calls
               originating from or terminating at MSDW that are Blocked during
               the Busy Hour, by (ii) the number of attempted calls originating
               from or terminating at MSDW during the Busy Hour, expressed as a
               decimal preceded by "P" (e.g., P.010").

          (c)  "Repair Time" for Voice Services means the actual time between
               (i) the earlier of (A) the moment when MSDW provides IBM with
               notice of any Outage or Problem with respect to a Service or
               Services by calling the IBM Help Desk and a Problem ticket is
               opened or (B) the moment when the IBM Help Desk otherwise becomes
               aware of such Outage or Problem and a Problem ticket is opened,
               and (ii) the moment that the affected Service(s) and those
               elements of the Service for which IBM is responsible are restored
               to normal operational status and such ticket is subsequently
               placed on hold. IBM problem tickets are closed upon the mutual
               agreement of IBM and MSDW. In the event that MSDW is not
               satisfied with the handling of an Outage or Problem, or if such
               Outage or Problem is perceived by MSDW to be chronic in nature,
               MSDW may request a root-cause analysis from IBM to review the
               specific cause or causes of such Outage or Problem, and IBM shall
               promptly provide such analysis.

          (d)  "Voice Network" means all Equipment, associated attachments,
               features and accessories, Software, lines and cabling, including
               communication controllers, multiplexers, lines, modems, CSUs and
               DSUs, and any other facilities used to connect and transmit voice
               communications. "Voice Network" does not include any MSDW
               Equipment, MSDW Software, or MSDW wiring.

     1.2  Other Terms.
          -----------

     25.  OTHER CAPITALIZED TERMS USED IN THIS ATTACHMENT B-4 BUT NOT DEFINED
     HEREIN SHALL HAVE THE MEANINGS GIVEN TO THEM ELSEWHERE IN THE AGREEMENT.

/1/ MACs Services provided by IBM include, as applicable, installations,
replacement of equipment, upgrades, disconnects, reconfigurations, and
optimizations for Voice Network equipment, facilities and software. Each MSDW
Business Unit and IBM will agree upon all MACs projects. If additional resources
are required to meet requested time frames other than as required by the
applicable Business Delivery Standard, IBM will provide appropriate cost
estimates and schedule a reasonable time in advance for approval by the
appropriate MSDW Business Unit personnel. In such situations where IBM provides
Voice Services, IBM will order, on behalf of the corresponding MSDW Business
Unit, all Voice Network applications, as well as long distance and "800"
services. For each project that IBM manages for an MSDW Business Unit, IBM will
(i) identify all necessary equipment, needs for additional footprint (by site
survey), and electrical requirements, (ii) provide a project manager/implementor
to oversee a project from beginning to completion and place applicable orders
for third party vendor involvement for which IBM is responsible, and (iii)
coordinate all installation efforts with the corresponding MSDW Business Unit
headquarters, as appropriate, and local site contacts. For MACs Services related
to large change projects as mutually defined by an MSDW Business Unit and IBM,
time frames will be determined as mutually agreed upon by such MSDW Business
Unit and IBM. Circuit and Toll Free Number moves, adds and changes will be
tracked in the { * } system.
/2/ MACs Times for the Toll Free Number change Business Delivery Standard
measures the elapsed time between the point when an MSDW Business Unit requests
IBM to perform Quick Allocator and scheduled Plan Override (change to the
current schedule set) changes. This includes time to receive a request, analyze
a request, make the change and
