     This Information Technology Services Agreement ("Agreement"), dated as of
     July 16, 1996, is by and between ADVO, Inc., a corporation having a place
     of business at One Univac Lane, Windsor, CT 06095 ("ADVO"), and Integrated
     Systems Solutions Corporation, {d/b/a/ISSC}, a wholly owned subsidiary of
     International Business Machines Corporation, having its headquarters at
     Route 100, Somers, NY 10589 ("ISSC"). ADVO and ISSC agree that the
     following terms and conditions will apply to services provided by ISSC
     under this Agreement. ADVO and ISSC may be referred to individually as a
     "Party" and collectively as the "Parties".

1.0  Background and Objectives 

     ADVO desires that the Information Technology Services as described herein
     and currently performed by or for ADVO be performed and managed by ISSC.
     ISSC has conducted due diligence to determine its ability to perform and
     manage such activities and responsibilities and desires to provide the
     Information Technology Services, defined herein, to ADVO.

     ADVO's objectives in entering into this Agreement are as follows:

     a)  establishing a price for the known scope of work so that ADVO's
         expenditures on information technology services for this work would be
         no higher under the Agreement than they would have been if ADVO
         continued to perform the same arrangements on its own;

     b)  structuring the provisions concerning future services for unknown scope
         or the migration of services from a mainframe environment to a mid-
         range or server environment so that ADVO's costs for such future
         services or costs of and after migration would be at least as favorable
         to ADVO under the Agreement as they would have been if ADVO had not
         entered into the Agreement and performed such future services on its
         own; and

     c)  assuring that the Services are delivered in a way that

         1)   does not unnecessarily increase ADVO's dependence on ISSC, or
              ADVO's costs, for New Services or for services after the
              termination of this arrangement;

         2)   minimizes the costs and effort of ADVO's migration from ISSC at
              the termination of the Agreement; and

         3)   does not reduce ADVO's ability to take advantage of new technology
              in order to improve its services or reduce its costs.

     ISSC will assist ADVO in achieving the above objectives as further set
     forth herein.

     After careful evaluation of ISSC's proposals and other alternatives, ADVO
     agrees to purchase from ISSC the Information Technology Services during the
     Term. This Agreement documents
<PAGE>
 
     the terms and conditions under which ADVO agrees to purchase and ISSC
     agrees to provide the Services.

3.0  Overview 

3.1  Transition of Services 

     a)  There will be a transition period ("Transition Period") during which
         transition shall be accomplished in accordance with the Transition Plan
         more fully described in Schedule H. ISSC shall migrate the information
         technology services performed by or for ADVO from ADVO to the ISSC Data
         Center. During the Transition Period, ADVO will be responsible for
         providing such services. The Transition Period may be extended by
         mutual agreement of the Parties.

     b)  During the Transition Period, the Parties will commence and complete a
         written plan to be mutually agreed upon that is consistent with
         Schedule H. Such plan shall be set forth in Section H-2 of Schedule H
         for the transition of the necessary resources from ADVO to ISSC. ADVO
         will cooperate with ISSC in accomplishing all aspects of the
         transition, including the commitment of the resources necessary to
         complete the transition during the Transition Period. An outline of the
         tasks necessary to accomplish the migration of the Services to ISSC is
         set forth in Section H-1 of Schedule H.

     c)  The Transition Plan will provide that at least two weeks prior to the
         cutover date to the ISSC Data Center from ADVO, as set out in the
         Transition Plan, ISSC will have established and tested systems at the
         ISSC Data Center which are capable of functionally duplicating all data
         processing Services then being
<PAGE>
 
         performed by ADVO. Prior to cutover to the ISSC Data Center, ISSC will
         implement the portion of the Transition Plan which will require testing
         designed to establish that the ISSC Data Center is capable of providing
         such Services.

     d)  ISSC shall maintain the redundancy described in subsection 3.1(c), at
         no additional cost to ADVO, for at least two weeks after cutover to the
         ISSC Data Center (the "Redundancy Period"). The Redundancy Period shall
         end on October 19, 1996 unless there is a cutback to the redundant
         facility prior to that date. If there is such a cutback, the Parties
         will use all reasonable efforts to cut over on as timely a basis as
         practicable. In no event shall the redundancy be maintained beyond
         December 15, 1996. In order to maintain redundancy during the
         Redundancy Period, ISSC will not use ADVO Machines to provide the data
         processing Services, except as necessitated by a failure of the
         transition to the ISSC Data Center, as set out below. As further set
         out below, ISSC shall be responsible for the reasonable, necessary and
         verified additional direct costs to ADVO of such redundancy, including
         any such incurred software license charges during the Redundancy
         Period. The Transition Plan shall include provisions for cutting back
         to ADVO's system if, during the Redundancy Period, either:

         1)   the weekly average for Systems Availability, as defined in
              Schedule E, falls below 90%; or

         2)   there is any single outage of greater than 8 hours in any rolling
              24 hour period impacting Systems Availability.

     e)  The Transition Plan will provide for migration to the ISSC Data Center
         on or before September 29, 1996 or October 5, 1996 as the case may be.
         However, if during the Redundancy Period ISSC fails to complete the
         Customer Test milestone, as set out in the Transition Plan, then:

         1)   ADVO may delay migration to the ISSC Data Center until December
              15, 1996 (the "Hold Period"). During the Hold Period ISSC shall be
              responsible for providing the data processing Services described
              herein using the Machines, necessary personnel and facilities then
              employed by ADVO.

         2)   During the Hold Period ADVO represents that its total liquidated
              damages arising out of or related to such delay will total
              $1,568,000. ISSC will proportionately credit this amount on a
              monthly basis, as ADVO's sole and exclusive remedy for such delay,
              against each month's portion of the Annual Services Charge during
              the Hold Period.

3.2  Staff

     a)  ADVO will use reasonable efforts to maintain staffing of the ADVO
         Network, AD/M functions, and print operations prior to and during the
         Transition Period; provided, however, that ADVO shall
<PAGE>
 
         not be obligated to increase staffing levels.

     b)  During the Transition Period ISSC or its subcontractors may interview
         those ADVO employees listed on Schedule O (the "Affected Associates").
         All Affected Associates designated on Schedule O as "Data Center" will
         be interviewed. ISSC may waive the interviews for those Affected
         Associates designated on Schedule O as "Key Associate" and as "AD/M".

     c)  Upon the Commencement Date, if not made previously, ISSC will make
         offers for employment to those ADVO employees designated on Schedule O
         as "Key Associate" and "AD/M" provided they:

         1)   are employed by ADVO as of the date the offer is made; 

         2)   have submitted an application for employment; 

         3)   meet ISSC's customary preemployment screening procedures for
              interviews, drug screening, and background verification; and

         4)   accept the offer of employment from ISSC within seven days from
              the date the offer is made.

     d)  By no later than 90 days after the Commencement Date, ISSC will offer
         employment to those Affected Associates designated on Schedule O as
         "Key Associate" and as "Data Center" provided they satisfy sections
         3.2.(c)(1) through 3.2.(c)(4) above. All other Affected Associates
         designated on Schedule O as "Data Center" but not as "Key Associate"
         will be considered for positions at other ISSC locations.

     e)  ISSC or its subcontractors will be solely responsible for making any
         hiring decisions regarding the Affected Associates.

     f)  All Affected Associates remaining on ADVO's payroll shall perform their
         duties under the direction and control of ADVO and will be treated as
         ADVO employees for all purposes throughout the Transition Period;
         provided, however, that nothing herein shall be interpreted so as to
         relieve ISSC of its obligations to provide the Services as of the
         Commencement Date.

     g)  Replacements for the Affected Associates shall be selected by ISSC as
         it deems necessary consistent with Section 4.1(d), and ISSC shall have
         financial responsibility for salary and benefits for replacements of
         Affected Associates.


     h)  Each offer of employment to an Affected Associate shall include:

         1)   an initial base salary not less than the base salary each such
              Affected Associate currently receives from ADVO; and

         2)   a benefits package, equivalent to the package available to ISSC 
<PAGE>
 
              employees who have accrued the same number of years of service
              with ISSC that the Affected Associate has accrued with ADVO. The
              benefits package includes (i) vacation days, up to ISSC's cap, and
              (ii) current participation in retirement benefits.

     i)  ISSC shall conduct all employment practices described herein in
         accordance with all applicable laws.

3.3  Software 

     As of the Commencement Date, and from time to time thereafter, ADVO will
     make the Software available to ISSC solely for the purpose of providing the
     Services and ISSC will be responsible for managing the Systems Software
     Licenses listed in Schedule F and for paying all related expenses,
     including the Systems Software maintenance fees beginning after the
     maintenance period date specified in Schedule F. Subject to the Parties
     obtaining any Required Consents in accordance with Section 3.4, ISSC will
     comply with all obligations of ADVO, including those of nondisclosure,
     under any such Systems Software License to the extent such obligations were
     disclosed to ISSC on or before the Commencement Date, and from time to time
     thereafter, through receipt by ISSC of a copy of the relevant documents,
     the receipt of which will be acknowledged by ISSC. ADVO represents and
     warrants that all obligations with respect to such Software Licenses
     accruing prior to the Commencement Date have been satisfied.

3.4  Required Consents

     ADVO shall be responsible for obtaining all Required Consents necessary to
     enable ISSC to use the Software and ADVO Machines except for Required
     Consents from ISSC Affiliates, which shall be obtained by ISSC. ADVO shall
     bear the costs, if any, of obtaining all Required Consents except for
     Required Consents from ISSC Affiliates, the costs of which shall be borne
     by ISSC. In the event that any Required Consent is not obtained with
     respect to the Software Licenses and ADVO Machines, then, unless and until
     such Required Consents are obtained, the Parties shall cooperate with each
     other in achieving a reasonable alternative arrangement for ADVO to
     continue to process its work with minimum interference to its business
     operations. Such failure by ADVO to obtain any Required Consent shall not
     per se be a breach of this Agreement by ADVO to the extent it participates
     in the foregoing.

3.5  Agency and Disbursements 

     Beginning on October 1, 1996, ISSC will pay the Software vendors and
     suppliers listed in Schedule F or reimburse ADVO in a timely manner for
     payments made by ADVO to such vendors and suppliers for periods after the
     maintenance period date specified in Schedule F.
<PAGE>
 
     ADVO appoints ISSC as its limited agent for the purposes of administration
     and payment as it pertains to the Software Licenses and ADVO shall not
     terminate, extend or amend such Software Licenses without the prior written
     approval of ISSC. ADVO agrees to promptly notify all the appropriate third
     parties of such appointment, such reasonable notification shall not be
     deemed to violate any confidentiality obligation of ADVO to ISSC.

     ISSC may terminate, cancel, substitute or change such Software Licenses as
     it chooses so long as ISSC continues to perform the Services in the manner
     required by this Agreement, provided ISSC (i) demonstrates to ADVO's
     satisfaction that any new arrangement can be migrated upon termination of
     this Agreement, and (ii) ISSC obtains ADVO's prior written consent which
     consent shall not unreasonably be withheld. Further, ISSC shall promptly
     pay or reimburse ADVO for any termination penalties, damages payable by
     ADVO to such third parties that are directly attributable to ISSC's
     decision to breach the third party agreement or to other termination
     charges associated with and paid by ADVO for such action.

3.6  Joint Verification 

     During the 90 day period following the Commencement Date, ISSC and ADVO
     reserve the right to inventory, validate and update, any information that
     is reflected in or omitted from the attached Supplement or Schedules. If
     discrepancies are detected during such period, the Parties shall attempt to
     negotiate in good faith modifications to the Supplement or Schedules and/or
     an equitable adjustment to the Annual Services Charge. If the Parties are
     unable to reach agreement on modifications or an equitable adjustment, then
     the Parties will submit the matter to the Joint Advisory Committee for
     dispute resolution as specified in Section 16 of this Agreement.

     Nothing in this Section shall prevent the Parties from exercising any other
     remedies available to them at law or under this Agreement; including, but
     not limited to, any termination remedies.

3.7  Other Obligations 

     Beginning on the earlier of the date this Agreement is executed by the
     Parties or the Commencement Date, ADVO will not enter into any new or amend
     any existing agreements or arrangements, written or oral, affecting or
     impacting upon Affected Associates or Software Licenses, as specified in
     the various Schedules to this Agreement, without the prior written consent
     of ISSC, which consent shall not unreasonably be withheld.

3.8  Software Currency

     The Parties agree to maintain reasonable currency for releases and versions
     of Software, unless otherwise mutually agreed. For
<PAGE>
 
     purposes of this Section, "reasonable currency" shall mean that the
     installed version or release is no more than one version or release older
     than the newest commercially-available version or release, unless otherwise
     agreed to by the Parties, and subject to the Change Management Procedures
     outlined in Section 4.5(b). If, upon the Commencement Date, any Software is
     not reasonably current, the Parties will not be obligated to bring such
     Software into reasonable currency immediately. The Parties will, as part of
     the AD/M Services described in Schedule E, prepare a plan for either (a)
     bringing the Software into reasonable currency, or (b) replacing the
     Software.

     In the event either Party requests the other Party to delay upgrading of
     specific Software beyond the reasonable currency period or requires
     operation and maintenance of multiple versions of Software, the other Party
     shall do so, provided, that if such Party:

     a)  is prevented from taking economic or performance advantage of
         technological advancements in the industry; or

     b)  incurs additional costs (e.g., Software support costs due to withdrawal
         of maintenance by the licensor, multiple version charges, etc.); then,

         the requesting party will either update the Software to the current
         level or reimburse the other party for any increased costs incurred
         pursuant to the above.

         In addition, in the case where ADVO is the requesting Party, ADVO shall
         relieve ISSC from compliance with any related Performance Standards
         until such time as the affected Software is deemed current to the
         extent such failure to comply is a direct result of delayed upgrading.

3.9  ADVO Approvals and Notification

     For those areas of the Services where ADVO:

     a)  has reserved right-of-approval or consent or agreement;

     b)  is required to provide notification; and/or

     c)  is required to perform a responsibility set forth in this Agreement;
         and

         such approval, consent, notification or performance is delayed or
         withheld by ADVO without authorization or right (which authorization or
         right shall be deemed to include the right of ADVO to reasonably object
         or to deny consent) beyond the period provided in this Agreement or the
         Schedules and such delay or withholding is not caused by ISSC and
         affects ISSC's ability to provide the Services under this Agreement,
         then ADVO will relieve ISSC of the responsibility for that portion of
         the
<PAGE>
 
         Services affected by the delay or withholding during the period such
         approval, consent, notification or performance is delayed or withheld
         beyond the period provided in this Agreement or the Schedules and ADVO
         will reimburse ISSC for all additional expenses, if any, incurred
         during such period as a result thereof.

         For purposes of this Agreement, if a time period is not specified for
         such approval, consent, agreement, notification or performance, then
         such time period shall be deemed to be not greater than ten business
         days.

4.0  ISSC Responsibilities 

4.1  ISSC Personnel 

     ISSC will designate, prior to the Commencement Date, an ISSC Project
     Executive to whom all ADVO's communications may be addressed and who has
     the authority to act for and bind ISSC and its subcontractors in connection
     with all aspects of this Agreement.

     a)  ISSC shall cause the person assigned to the position of Project
         Executive to devote substantially his or her full time and effort to
         the provision of the Services under this Agreement, and to the extent
         such Services are not provided from a dedicated facility, to the
         operation and management of the Data Center and AD/M staff. Before
         assigning an individual to the position of Project Executive, whether
         the individual is initially assigned or is subsequently assigned, ISSC
         shall:

         1)   notify ADVO of the proposed assignment; 

         2)   introduce the individual to appropriate ADVO representatives; and

         3)   consistent with ISSC's personnel practices, provide ADVO with any
              other information about the individual reasonably requested by
              ADVO.

              ISSC agrees to discuss with ADVO any objections ADVO may have to
              such assignment and attempt to resolve such concerns on a mutually
              agreeable basis.

     b)  ISSC will undertake to minimize change of the Project Executive and
         will give ADVO at least 30 days advance notice of a change of the
         Project Executive and will discuss with ADVO any objections ADVO may
         have to such change.

     c)  In the event that ADVO reasonably and in good faith determines that it
         is not in the best interests of ADVO for any ISSC employee or
         subcontractor to continue performing any of the Services, then ADVO
         shall give ISSC written notice specifying the reasons for its position
         and requesting that the employee or
<PAGE>
 
         subcontractor be replaced. Promptly after its receipt of such a notice,
         ISSC shall investigate the matters stated in such notice and, if it
         determines that ADVO's concerns are reasonable, ISSC shall take
         appropriate action.

    d)   The Parties agree that it is in their best interests to keep the
         turnover rate of the ISSC and ISSC subcontractor personnel performing
         the Services to a reasonably low level. Accordingly:

         1)  for at least the first nine months following the Commencement Date,
             ISSC will not reassign any Affected Associate, for so long as the
             Affected Associate continues to be employed by ISSC, in a way that
             prevents him or her from spending substantially all of his or her
             time performing Services hereunder unless the Affected Associate
             requests reassignment or unless ADVO consents to such reassignment,
             which consent shall not be unreasonably withheld; and

         2)  for so long as the Affected Associate continues to be employed by
             ISSC, ISSC will not reassign any Affected Associate identified on
             Schedule O as "Critical/System", unless the Affected Associate
             requests reassignment or unless ADVO consents to such reassignment,
             which consent shall not be unreasonably withheld, until the earlier
             of: (i) full documentation of the system for which the Affected
             Associate was responsible in a form reasonably satisfactory to
             ADVO, or (ii) replacement of the system for which the Affected
             Associate was responsible.

    Further, if ADVO reasonably determines that the personnel turnover rate is
    or may be excessive and so notifies ISSC, ISSC shall provide data regarding
    the turnover rate and shall meet with ADVO to discuss the reasons for the
    turnover rate. If reasonably requested by ADVO, ISSC shall submit to ADVO
    its proposals for reducing the turnover rate, or seeking to prevent an
    excessive turnover rate, and the Parties shall mutually agree on a program
    promptly to maintain or reduce the turnover rate to an acceptable level, as
    appropriate. In any event, notwithstanding transfer or turnover of
    personnel, ISSC remains obligated to perform the Services without
    degredation and in accordance with this Agreement.

    4.2 Standards 

        ISSC agrees that: 

        a)  all Services performed by ISSC for ADVO will be performed in a
            professional and workmanlike manner in accordance with industry
            standards and practices applicable to the performance of such
            Services; and

        b)  its performance of the Services will meet or exceed each of the
            applicable Performance Standards.

    4.3 Efficient Use of Resources 
<PAGE>
 
     ISSC shall take reasonable action, taking into account economic
     circumstances, to efficiently use resources that will be chargeable to ADVO
     under this Agreement including, but not limited to:

     a)  making schedule adjustments (consistent with ADVO's priorities and
         schedules for the Services and ISSC's obligation to meet the
         Performance Standards);

     b)  delaying the performance of noncritical functions within established
         limits; and

     c)  tuning or optimizing the systems used to perform the Services. 

4.4  Technological Advancements 

     ISSC agrees to take reasonable action, taking into account economic
     circumstances, without an increase in charges to ADVO, subject to the
     provisions of Section 6.5 and the Performance Standards, to provide the
     Services to ADVO at a technological level that will enable ADVO to take
     advantage of technological advancement in its industry.

     Further, ISSC may, at ISSC's option and expense, implement technological
     advancements relative to the provision of the Services; provided, however,
     ISSC continues to perform the Services in accordance with the Performance
     Standards set forth in this Agreement. Notwithstanding the foregoing, ISSC
     shall not without ADVO's express consent, and unless only in effect during
     the Term, implement any technological advancement that materially adversely
     affects ADVO's ability, at expiration or termination of this Agreement, to
     migrate to: (i) another technology platform, or (ii) another services
     provider, or (iii) ADVO itself.

     If such technological advancement(s) will have an effect on any Baseline(s)
     and/or ARC/RRC Rate(s) for any resource provided under the Agreement, ISSC
     will normalize such affected Baseline(s) and/or ARC/RRC Rate(s), consistent
     with the rebaselining procedures set forth in Schedule J, so that ADVO
     receives the same level of performance and the same price-performance as
     provided under the methodology used at inception of this Agreement. ISSC
     will review with ADVO the conversion methodology (e.g., benchmarking,
     historical data, etc.) which ISSC used to support such adjustment(s).

     ISSC will explore the implementation of technological advancements
     reasonably requested by ADVO.

4.5  Management and Control 

     a)  Within 180 days after the Commencement Date, ISSC shall provide a
         manual describing the operating processes and procedures relating to
         the performance of the Services (the "Procedures

             operations of ADVO without first obtaining approval from ADVO.
     
         2)  ISSC will assure that all programs are moved from the application
             development and test environments to the production environment in
             a controlled and documented manner.
    
         3)  ISSC will schedule all Data Center and AD/M projects so as not to
             unreasonably interrupt ADVO business operations.
    
         4)  ISSC will prepare monthly, a rolling quarterly "look ahead"
             schedule for ongoing and planned Data Center and AD/M changes. The
             status of changes will be monitored and tracked against the
             applicable schedule.

         5)  ISSC will document and provide to ADVO a notification of all Data
             Center and AD/M changes performed for emergency purposes or as
             otherwise not precluded in Section 4.5(b)(1) as soon as
             practicable, but in no event later than five business days after
             change was made.

     Regardless of whether the Procedures Manual or Change Management Procedures
     or components thereof are completed on schedule, unless otherwise specified
     in the Transition Plan in accordance with Schedule H, the above procedures
     will be applicable from the Commencement Date.
    
     The Change Management Procedures will be included in the Procedures Manual
     and shall be provided to ADVO for review, comment, and approval, and any
     reasonable comments or suggestions of ADVO will be incorporated therein.

    c)  Upon reasonable request by ADVO, ISSC will provide periodic reports to
        ADVO that will include, at a minimum, the following:

              described in Section 4.5(b)(5);

         3)   a monthly change report setting forth a record of all changes
              performed during the previous month; and

         4)   a monthly report describing ADVO's utilization of each particular
              type of RU during such month, and comparing such utilization to
              the then applicable Baseline for each RU.

     ISSC will provide ADVO with such documentation and other information as may
     be reasonably requested by ADVO from time to time in order to verify the
     accuracy of the reports specified above.

     d)  The Parties will mutually determine an appropriate set of periodic
         meetings to be held between representatives of ADVO and ISSC. ISSC will
         attend all such meetings. The agenda will be mutually agreed upon in

4.16 Audits

     In accordance with this Section, SAS-70, and any other regulatory
     requirements, ADVO may have an independent third party audit conducted of
     the facilities. The audit objective will be to report on the internal
     control structure employed by ISSC for the duration of this Agreement and
     will include reviews of: computer operation procedures, backup, off-site
     storage, contingency planning, DASD management controls, physical security,
     software and data security, systems software support, tape library control
     and other areas as reasonably deemed appropriate.

     ISSC will reasonably assist ADVO in meeting its audit and regulatory
     requirements and in reasonably minimizing costs associated with such
     requirements, including providing access to the Data Center to enable ADVO
     and its auditors and examiners to conduct appropriate audits and
     examinations of the operations of ISSC relating to the performance of the
     Services to verify:

     a)  the accuracy of ISSC's charges, other than the Annual Services Charge,
         to ADVO;
         
     b)  that ISSC is exercising reasonable procedures to control the resources
         provided by ADVO to ISSC such as heat, light and utilities utilized in
         providing Services to ADVO; and

     c)  that Services are being provided in accordance with the Performance
         Standards.
         
     Such access will require 24 hours notice to ISSC and will be provided at
     reasonable hours, provided that any audit does not interfere with ISSC's
     ability to perform the Services in accordance with the Performance
     Standards. ISSC will provide access only to information reasonably
     necessary to perform the audit. ISSC will provide access to ISSC
     proprietary data, subject to the provisions of Section 9. Under no
     condition will ADVO have access to the data of other ISSC customers. ISSC
     will also assist ADVO's employees or auditors in testing ADVO's data files
     and programs, including, without limitation, installing and running audit
     software, subject to the provisions of Section 6.
<PAGE>
 
     Subject to Section 6.5, ISSC agrees to make any changes and take other
     actions which are necessary in order to maintain compliance with applicable
     laws or regulations or generally acceptable accounting procedures. ADVO may
     submit additional findings or recommendations to ISSC for its
     consideration, and ISSC shall consider such findings and ISSC shall
     implement such findings and recommendations it reasonably determines to be
     appropriate.
     
     If any audit or examination reveals that ISSC's invoices for the audited
     period are not correct for such period, ISSC shall promptly reimburse ADVO
     for the amount of any overcharges, or ADVO shall promptly pay ISSC for the
     amount of any undercharges.

4.17 Benchmarks

     Beginning in the second contract year from the Commencement Date, and no
     more than once in a calendar year, ADVO reserves the right to have a third
     party that has been mutually agreed upon between ADVO and ISSC, conduct a
     confidential benchmark study at ADVO's expense to compare the cost, quality
     and delivery of the Services being benchmarked to services provided to
     other entities receiving comparable services (the "Benchmark"). The
     Benchmark will be designed to provide a representative comparison of the
     benchmarked services provided by vendors across various industries. Subject
     to appropriate confidentiality restrictions, ISSC will reasonably cooperate
     with such third party in performing the Benchmark provided ISSC receives
     reasonable notice and that any Benchmark does not interfere with ISSC's
     ability to perform the Services in accordance with the Performance
     Standards.

     ADVO will determine the scope of the study and the categories to be
     compared. The Parties will mutually determine necessary adjustments to
     address comparability factors of the total scope of Services such as the
     Term of the Agreement, complexity of the transition to ISSC's Services, and
     environmental or other unique aspects of the Services. Upon request by
     ADVO, the Parties will analyze the Benchmark results and ISSC, at its
     expense (unless the Benchmark fails to comport with the scope of the
     categories studied or adjustments as agreed between ADVO and ISSC, or the
     Benchmark results can be shown to be based on factually inaccurate
     assumptions or data or other inputs upon which the conclusions are based,
     in which case the Benchmark can be corrected for such deviations) and
     within 60 days of completion of the Benchmark, will:

     a)  prepare an analysis report to address any material deviations, higher
         or lower, of the cost, quality, or delivery of the Services as compared
         to the Benchmark results; and

     b)  prepare a plan for achieving higher levels of service and/or improved
         price performance.
<PAGE>
 
         ISSC and ADVO will implement the plan when and to the extent it is
         approved by ADVO to the extent such implementation is feasible.

ADVO shall provide ISSC, to the extent ADVO has such license rights, with source
code that matches all application load modules executed in the production
environment for Applications Software.

ADVO may reasonably audit, control and approve all new Applications Software
prior to its promotion into production.

5.3  Facilities

To enable ISSC to provide the Services, ADVO agrees:

     a)  to provide, at no charge to ISSC, the use of the ADVO facilities and
         such additional space as may be reasonably necessary for the
         performance of the Services. This includes reasonable office space for
         a minimum of 60 people and individual offices for four managers,
         storage space, telephone capability (but excluding long-distance
         telephone charges, for which ADVO will be reimbursed by ISSC), office
         support services (e.g., janitorial and security), office supplies and
         furniture. ADVO shall be responsible for ensuring such ADVO facilities
         provide for a safe working environment, including compliance with
         national, state and local codes, ordinances, laws, authorities having
         jurisdiction and nationally recognized standards;

     b)  to provide, for the ADVO facilities located at premises under ADVO's
         management and control during the Term the utilities as may reasonably
         be necessary for ISSC to perform the Services as described in this
         Agreement, such as heat, light, power, air conditioning,
         uninterruptible power supply, and such other similar utilities;
<PAGE>
 
     c)  to provide access to ADVO parking and cafeteria (if any) facilities for
         ISSC employees;

     d)  if ADVO decides to relocate its current facility from which the
         Services are being provided, ADVO will provide comparable space,
         facilities and resources in the new location and reimbursement of
         personnel relocation for ISSC employees and subcontractors under the
         same terms and conditions of this Agreement; and

     e)  following the expiration or termination of this Agreement, ADVO will
         allow ISSC the use, at no charge, of those ADVO facilities then being
         used to perform the Services for up to 60 days following the effective
         date of such expiration or termination (or from the last day of any
         Services Transfer Assistance period) to enable ISSC to affect an
         orderly transition of ISSC resources.

     It is understood that ISSC's use of the ADVO facilities does not constitute
     or create a leasehold interest. When the ADVO Network and/or the other ADVO
     facilities are no longer being utilized by ISSC to perform the Services,
     ADVO's obligations set forth in this Section with respect to the ADVO
     Network and/or the other ADVO facilities will cease.

5.4  Support Services

     ADVO agrees to:

     a)  perform its responsibilities in accordance with the Procedures Manual
         and Performance Standards and until such time as those documents are
         completed, in whole or in part, in accordance with ADVO's practices and
         policies as of the Commencement Date;

     b)  provide to ISSC, to the extent not otherwise sold, assigned or licensed
         to ISSC, for the purposes of meeting its obligations under this
         Agreement, full access to, and use of, Machines and Software on the
         terms and conditions set forth in this Agreement;

     c)  supply the End User Machines and software being used by the Affected
         Associates as of the Commencement Date for 180 days from the
         Commencement Date. Such machines and software shall remain the property
         of ADVO. Any replacement machines or software will be the
         responsibility of ISSC and such replacements will be the property of
         ISSC; and

     d)  maintain and replace as necessary any machines retained by ADVO and
         required by ISSC to operate Applications Software.

5.5  Other Responsibilities

     ADVO also agrees to:

     a)  provide data entry and coordinate such activities with ISSC's systems
         design and production functions as described in Schedule
<PAGE>
 
         E;

     b)  be responsible for Network including WAN and LAN management, voice
         services and voice network services;

     c)  be responsible for all servers except for servers operating
         Applications Software for which ISSC has operational responsibility;

     d)  provide for maintenance of the input/output devices in the ADVO
         Network;

     e)  designate and document application information requirements, including
         report design and content, frequency of reports, and accessibility to
         information;

     f)  provide additions, upgrades and replacements for all End User Machines
         used by ADVO employees;

     g)  maintain and support all End User Machines used by ADVO employees;

     h)  provide personnel and equipment to reasonably ensure the physical
         security of ADVO facilities;

     i)  provide all preprinted forms;

     j)  provide all paper forms and supplies required by End Users employed by
         ADVO;

     k)  pay all usage fees for disaster recovery contracts, if any, until
         completion of migration to the ISSC Data Center;

     l)  be responsible for all mail, messenger, postage, courier and print
         distribution services;

     m)  be responsible for all costs associated with off-site data storage;

     n)  be responsible for such other ADVO activities and functions as are
         described in this Agreement; and

     o)  cooperate to establish the required FP Baselines within the time
         required as further set forth in Schedule E hereto, without undue
         delay.

6.0  Charges and Expenses

6.1  Annual Services Charge

     ADVO agrees to pay the Annual Services Charge specified in the Supplement
     for each year of the Term together with the other amounts and subject to
     credits as described in this Section 6 and Section 7 and set forth in the
     Supplement.
<PAGE>
 
6.2  Resource Charges and Credits

One month after the establishment of Baselines, other than Help Desk Baselines,
pursuant to Schedule J, and monthly thereafter, ISSC will review the quantity of
Resource Units utilized by ADVO during the preceding month, and calculate
Additional Resource Charges (ARCs) and/or Reduced Resource Credits (RRCs) in
accordance with the Supplement and Schedule J.

Six months after the establishment of Help Desk Baselines pursuant to Schedule
J, and every three months thereafter, ISSC will review the cumulative quantity
of Resource Units utilized by ADVO during the preceding three months, and
calculate Additional Resource Charges (ARCs) and/or Reduced Resource Credits
(RRCs) in accordance with the Supplement and Schedule J.

ADVO agrees to pay Additional Resource Charges in accordance with Section 7.
ISSC agrees to credit Reduced Resource Credits in accordance with Section 7.

6.3  Cost of Living Adjustment

ADVO agrees to pay ISSC a Cost of Living Adjustment ("COLA"), in accordance with
Schedule J if the actual cumulative year-to-year inflation increases.

The Parties agree to use the December unadjusted Consumer Price Index, as
published in the "Summary Data from the Consumer Price Index News Release" by
the Bureau of Labor Statistics, U.S. Department of Labor, For All Urban
Consumers, ("CPI-U"), for purposes of determining actual inflation.

6.4  New Entities

If ADVO acquires any additional Affiliate during the Term and ADVO desires that
ISSC provide Services for such Affiliate, subject to additional charges if
acceptance of such responsibilities would require New Services as described in
Section 6.5 and/or resources in excess of existing Baselines, then ISSC will
provide such Affiliate with Services in accordance with this Agreement.

6.5  New Services

In the event that ADVO requests ISSC to perform functions different from, and in
addition to, the Services ("New Services"), the charge to ADVO for ISSC
performing such functions will be determined as follows:

     a)  If the additional function requires only those resources which have a
         current Baseline, the additional function will not be considered a New
         Service and the charges for the incremental resources, if any, will be
         recovered through the ARC methodology, subject to a Baseline adjustment
         in accordance with
<PAGE>
 
         Schedule J.

     b)  If the additional function requires resources not covered by an
         existing Baseline and/or requires additional start-up expenses, then
         such additional function will be considered New Services, and prior to
         performing such New Services:

         1)  ISSC will quote to ADVO the adjustment in the Annual Services
             Charge or other payment method that will reflect such New Services,
             which will be based upon the required proportional adjustment in
             system and other applicable resources relative to the Annual
             Services Charge; and

         2)  ADVO, upon receipt of such quote, may then elect to have ISSC
             perform the New Services, and the Annual Services Charge and the
             Baselines will be adjusted, if necessary, to reflect such New
             Services.

6.6  Taxes

     a)  The Annual Services Charge and ARCs (if any) paid by ADVO are inclusive
         of any applicable sales, use, personal property or other taxes
         (exclusive of telecommunications taxes) attributable to periods on or
         after the Commencement Date based upon or measured by ISSC's cost in
         acquiring or providing equipment, materials, supplies or services
         furnished or used by ISSC in performing or furnishing the Services,
         including without limitation, all personal property and use taxes, if
         any, due on ISSC Machines and Systems Software.

     b)  In the event that a sales, use, excise or services tax is assessed on
         the provision of the Services (or any New Services) by ISSC to ADVO or
         on ISSC's charges to ADVO under this Agreement, however levied or
         assessed, ADVO will be responsible for and pay the amount of any such
         tax. ADVO will also be responsible for paying all personal property or
         use taxes due on or with respect to ADVO Machines, End User Machines
         and Applications Software and for the payment of any telecommunications
         taxes for network lines and circuits.

     c)  Each Party shall bear sole responsibility for all taxes, assessments
         and other real property-related levies on its owned or leased real
         property.

     d)  The Parties agree to reasonably cooperate with each other to more
         accurately determine each Party's tax liability and to minimize such
         liability to the extent legally permissible.

     e)  Each Party shall provide and make available to the other any resale
         certificates, information regarding out-of-state sales or use of
         equipment, materials or services, and other exemption certificates or
         information reasonably requested by either Party. The Parties will also
         work together to segregate the Annual Services Charge and ARCs into
         separate payment streams:
<PAGE>
 
         1)  that for taxable Services;

         2)  that for nontaxable Services;

         3)  that for which a sales, use or similar tax has already been paid by
             ISSC; and

         4)  that for which ISSC functions merely as a paying agent for ADVO in
             receiving goods, supplies or services (including leasing and
             licensing arrangements) that otherwise are nontaxable or have
             previously been subject to tax.

6.7  Extraordinary Reduction of ADVO Work

     a)  If, during the Term, ADVO experiences significant changes in the scope
         or nature of its business which have or are reasonably expected to have
         the effect of causing sustained substantial decreases in the amount of
         ISSC resources used in performing the Services, provided such decreases
         are not due to ADVO resuming the provision of such Services by itself
         or ADVO transferring the provision of such Services to another vendor,
         such changes shall be governed by this Section.

     Substantial decreases shall be considered:

         1)  a 35% or more decrease in the amount of ISSC resources used in
             performing AD/M Services; or

         2)  a 25% or more decrease in the total amount of ISSC resources used
             in performing all Services, including AD/M Services.

     Examples of the kinds of events that might cause such substantial decreases
     include but are not limited to; 

         1)  voluntary or involuntary bankruptcy;

         2)  changes to locations where ADVO operates; 

         3)  changes in ADVO's products or markets;

         4)  mergers, acquisitions or divestitures (which in the case of mergers
             or acquisitions could include the performance of some of the
             Services by the surviving third-party entity of the merger or the
             acquirer, or the designee of either of them, which shall be deemed
             not to be the transfer of Services to another vendor, provided that
             the merger or acquisition is primarily for business reasons
             unrelated to ADVO's avoidance of its obligations under this
             Agreement);

         5)  changes in the method of service delivery (other than use of
             another vendor); or
             
         6)  changes in market priorities.
<PAGE>
 
     b)  ADVO will notify ISSC of any event or discrete set of events which ADVO
         believes qualifies under this Section and ISSC will identify the
         changes that need to be made to accommodate the extraordinary decrease
         of resource requirements in a cost-effective manner without disruption
         to ADVO's ongoing operations, and the cost savings that will result
         therefrom in a plan that will be submitted to ADVO for review and
         acceptance.

     c)  Effective upon the occurrence of the event or discrete sets of events,
         unless otherwise notified by ADVO, ISSC will make any applicable
         adjustments to the charges and the Baselines to reflect the foregoing
         and distribute an amended Supplement to the Parties.

     d)  ADVO may, at its option and expense, employ an accredited and
         independent auditor to verify that ISSC's methodology for calculating
         the savings referenced in Section 6.7(b) above conform to accepted
         accounting practices, and to verify that ISSC's methodology captures,
         for ADVO's benefit, any savings resulting from the extraordinary
         reduction in resource requirements. ADVO may raise any discrepancy it
         may have with the adjustment made pursuant to Section 6.7(c) above by
         disputing the first invoice reflecting such adjustment pursuant to
         Section 7.5.

6.8  Services Transfer Assistance

     It is the intent of the Parties that at the expiration or termination of
     this Agreement, ISSC will cooperate with ADVO to assist with the orderly
     transfer of the services, functions and operations provided by ISSC
     hereunder to another services provider or ADVO itself. Prior to expiration
     or termination of the Agreement, ADVO may request ISSC to perform and, if
     so requested, ISSC shall perform (except in the event of a termination due
     to a failure by ADVO to pay any undisputed amounts due and payable under
     this Agreement) services in connection with migrating the work of ADVO to
     another services provider or ADVO itself ("Services Transfer Assistance").
     Services Transfer Assistance shall be provided until the effective date of
     expiration or termination with respect to the Services, and for expiration
     or termination related services other than those relating to the Services,
     for up to six additional months after the effective date of expiration or
     termination. Subject to Section 6.8(d) below, Services Transfer Assistance
     shall include, but not be limited to, providing ADVO and its Affiliates and
     their agents, contractors and consultants, as necessary, with services such
     as the following:

     a)  Premigration Services

         1)  freezing all noncritical Software changes,

         2)  notifying all outside vendors of procedures to be followed during
             the turnover phase,
<PAGE>
 
         3)  reviewing all Software libraries (tests and production) with the
             new service provider and/or ADVO,

         4)  assisting in establishing naming conventions for the new production
             site,

         5)  analyzing space required for the data bases and Software libraries,
             and
        
         6)  generating a tape and computer listing of the source code in a form
             reasonably requested by ADVO.

     b)  Migration Services

         1)  unloading the production data bases,

         2)  delivering tapes of production data bases (with content listings)
             to the new operations staff,

         3)  assisting with the loading of the data bases,

         4)  assisting in the execution of a parallel operation until the
             effective date of expiration or termination of this Agreement.

     c)  Postmigration Services

         1)  answering questions regarding the Services on an "as needed" basis,
             and

         2)  turning over of any remaining ADVO owned reports and documentation
             still in ISSC's possession.

     d)  If any Services Transfer Assistance provided by ISSC requires the
         utilization of additional resources for which there is a current
         Baseline that ISSC would not otherwise use in the performance of this
         Agreement, ADVO will pay ISSC for such usage at the then current
         Agreement charges. If the Services Transfer Assistance requires ISSC to
         incur expenses in addition to the expenses that ISSC would otherwise
         incur in the performance of this Agreement, then:

         1)  ISSC shall notify ADVO of any additional expenses associated with
             the performance of any additional services pursuant to this Section
             prior to performing such services;

         2)  upon ADVO's authorization, ISSC shall perform the additional
             services and invoice ADVO for such services; and

         3)  ADVO shall pay ISSC for such additional expenses incurred to
             provide the additional services within ten business days of the
             date of the invoice.

6.9  Other Expenses and Charges
<PAGE>
 
     ADVO will be financially responsible for all costs and expenses associated
     with its responsibilities specified in Section 5. Such costs and expenses
     are not included within the Annual Services Charge, ARCs or any other
     charges payable by ADVO under this Agreement.

7.0  Invoicing and Payment

7.1  Annual Services Charge Invoices

     ISSC will invoice ADVO on a monthly basis the proportional amount of the
     Annual Services Charge for that month in advance. The portion of the Annual
     Services Charge attributable to Applications Development will be separately
     stated on the invoice. The invoice will state separately applicable taxes
     owed by ADVO, if any, by tax jurisdiction.

7.2  ARC, RRC and COLA Invoicing

     Beginning three months following the establishment of the Baselines
     pursuant to Schedule J, ISSC will invoice ADVO quarterly for the amount
     due, if any, for the preceding three months. The invoice will detail a
     single, three-month ARC for Help Desk calls and three, one-month ARCs-less-
     RRCs calculations for Resource Units other than Help Desk calls.

     ISSC will invoice ADVO for COLA in accordance with Section 6.3.

7.3  Other Charges

     Any amount due under this Agreement for which a time for payment is not
     otherwise specified will be due and payable within 60 days after the date
     of the invoice.

7.4  Invoice Payment

     a)  Annual Services Charge and COLA Invoices:

     Beginning on or about the Commencement Date and at the beginning of each
     month thereafter, ISSC will invoice ADVO for the proportional amount of the
     Annual Services Charge. ADVO agrees to pay the charges within 30 days of
     the date of the invoice.

     b)  ARC and RRC Invoices:

     ADVO will pay each invoice within 60 days of the date of an invoice.

     In the event that any payments for charges not disputed by ADVO in
     accordance with Section 7.5 are not received by ISSC within five days
     following the due date, a late fee equal to the lower of two percent of the
     amount of such payment per month or the maximum amount allowed by
     applicable law shall also be paid to ISSC by ADVO.
<PAGE>
 
7.5  Disputed Charges

a)   In the event that ADVO has reasonable cause to believe an invoiced amount
     is in error, ADVO may withhold the disputed amount from the payment for
     such invoice and notify ISSC of the disputed amount in writing with
     appropriate documentation demonstrating ADVO's position. If ISSC agrees
     that the disputed amount is not due ISSC, it will notify ADVO in writing
     that it accepts ADVO's position and will correct the billing error with a
     credit on the next quarter's ARC/RRC invoice, unless the Parties mutually
     agree to an alternative invoice method for such correction. If ISSC
     determines that the disputed amount is due ISSC, in full or in part, it
     will notify ADVO in writing of the amount still due with appropriate
     documentation supporting its position. If the Parties still do not agree on
     the disputed amount, the matter will be addressed through the Dispute
     Resolution process as described in Section 16.2. Upon resolution:

     1)  if the disputed amount is due ISSC, ISSC will invoice ADVO for such
         amount on the next quarter's ARC/RRC invoice and ADVO will pay such
         amount in accordance with the payment terms defined in Section 7.4; or

     2)  if the disputed amount is not due ISSC, ISSC (once the dispute is
         resolved) will correct the billing error with a credit on the next
         quarter's ARC/RRC invoice, unless the Parties mutually agree to an
         alternative invoice method for such correction.

     Notwithstanding the foregoing, the maximum amount ADVO may withhold
     pursuant to this Section 7.5 shall not in the aggregate exceed one month's
     payment of the Annual Services Charge hereunder. ADVO shall pay disputed
     amounts above the foregoing threshold to ISSC under protest, without
     waiving any of ADVO's rights to recover such disputed amounts.

     b)  In the event that ADVO, as the result of an audit or other examination
         of its records, has reasonable cause to believe a previously-paid
         amount was in error, ADVO may report the disputed amount to ISSC in
         writing with appropriate documentation demonstrating ADVO's position.

         1)   If ISSC agrees that the disputed amount was not due ISSC, it will
              notify ADVO in writing that it accepts ADVO's position and will
              reimburse ADVO for the disputed amount by issuing a credit for
              such amount on the next quarter's ARC/RRC invoice, unless the
              Parties mutually agree to an alternative invoice method for such
              correction.

         2)   If ISSC determines that any portion of the disputed amount was, in
              fact, due ISSC, it will notify ADVO in writing of its findings
              with reasons for such determination. If the Parties still do not
              agree on the disputed amount, the matter will be addressed through
              the Dispute Resolution process as described in Section 16.2. Upon
              resolution, if any portion of the disputed
<PAGE>
 
              amount is due ADVO, ISSC will reimburse ADVO for such portion of
              the disputed amount by issuing a credit for such portion of the
              disputed amount on the next quarter's ARC/RRC invoice, unless the
              Parties mutually agree to an alternative invoice method for such
              correction.

     In the event such credits as described in this Section 7.5(b) are not
     issued to ADVO by ISSC in accordance with clause 7.5(b), a late fee equal
     to the lower of two percent of the amount of such payment per month or the
     maximum amount allowed by applicable law shall also be due to ADVO by ISSC.

7.6  Proration

     All periodic charges under this Agreement are to be computed on a basis of
     12 equal months, and will be prorated on a per diem basis for any partial
     month, unless specifically stated otherwise in this Agreement.

7.7  Refundable Items

     If ISSC should receive during the Term any refund, credit or other rebate
     in respect of a License which is attributable to a period prior to the
     Maintenance Period Date specified on Schedule F, ISSC will promptly notify
     ADVO of such refund, credit or rebate and will promptly pay to ADVO the
     full amount of such refund, credit or rebate.

     If ADVO should receive during the Term any refund, credit or other rebate
     in respect of a License which is attributable to a period on or after the
     Maintenance Period Date specified on Schedule F, ADVO will promptly notify
     ISSC of such refund, credit or rebate and will promptly pay to ISSC the
     full amount of such refund, credit or rebate.

7.8  Other Credits

     Except as otherwise set forth in this Agreement, with respect to any amount
     to be paid or reimbursed to ADVO by ISSC pursuant to this Agreement, ISSC
     may, at its option, pay that amount to ADVO by giving ADVO a credit against
     the charges otherwise payable to ISSC hereunder at the time any such amount
     is due and payable to ADVO.

     ISSC, at ADVO's sole option, shall have the following license rights:

     a)  an irrevocable, nonexclusive, worldwide, paid-up license to use,
         execute, reproduce, display, perform and distribute such Materials for
         the purpose of performing the Services for the sole benefit of ADVO
         during the Term; and

     b)  the right to sublicense third parties to do any of the foregoing.

8.4  General Rights 

     a)  At the expiration or earlier termination of this Agreement, so long as
         ADVO has not materially breached its obligations under this Agreement,
         ISSC will grant to ADVO the following license rights in the Materials
         owned by ISSC:

         1)   an irrevocable, nonexclusive, worldwide, paid-up license to use,
              execute, reproduce, display, perform, modify and distribute the
              Materials internally for the sole benefit of and exclusive use by
              ADVO and its Affiliates; and

         2)   the right to sublicense third parties to do any of the foregoing. 

     b)  Any ownership or license rights herein granted to either Party are
         limited by and subject to any patents and copyrights held by, and terms
         and conditions of any license agreements with,
<PAGE>
 
         applicable third party software providers and unless otherwise agreed
         to by the Parties, the Parties shall make a diligent effort to assure
         that no such license agreements unduly restrict use of such Materials
         for the benefit of the other Party or unduly increase the other Party's
         cost.

     c)  To the extent any of the Materials may not, by operation of law, be
         owned by the Party to which ownership has been granted (as described in
         this Section 8), each Party agrees to assign and hereby assigns,
         without further consideration, the ownership of all right, title and
         interest in all U.S. and foreign copyrights and mask work rights (if
         any) in such Materials to the other Party, and such assignee Party
         shall have the right to obtain and hold in its own name copyrights,
         registrations, renewals and all other rights relating or pertinent
         thereto.

     d)  The Parties agree to reproduce copyright legends which appear on any
         portion of the Materials which may be owned by third parties.

     e)  This Agreement shall not preclude ISSC from developing materials or
         providing services which are competitive to the Materials irrespective
         of their similarity to computer programming code, documentation or
         other materials or services which might be delivered pursuant to this
         Agreement, except to the extent any of same may infringe any of ADVO's
         patent rights or copyrights or disclose Confidential Information in
         violation of Section 9.

     For any Materials developed by ISSC personnel directly supporting ADVO
     during the Term, excepting ISSC Data Center operators, ISSC will use its
     reasonable good faith efforts to identify and provide information
     concerning such Materials to ADVO, and if ADVO notifies ISSC that such
     Materials contain or may contain information or materials or know-how
     unique to ADVO's type of business and/or proprietary to ADVO (but not in
     any instance network management or general data processing information or
     materials or know-how) (the "Sensitive Materials"), ADVO may request a
     review of such Materials to determine if they, in fact, contain such
     information or materials or know-how. If ADVO can reasonably make a showing
     that the Materials are Sensitive Materials, then ISSC shall limit its use
     of such Materials in the telecommunications and media industry to its own
     internal use; any other use of the Materials shall first be reviewed and
     approved by ADVO and such approval shall not be unreasonably withheld or
     delayed. Any disputes arising under this Section 8.4(e) shall be resolved
     in accordance with the dispute resolution provisions of Section 16.2.

     The employees of each Party during the Term may further develop their
     general knowledge, skills and experience. The subsequent use by such
     employees of such general knowledge, skills and expertise in the ordinary
     course of business does not constitute a breach of this Agreement provided
     it does not infringe any
<PAGE>
 
     intellectual property rights of the disclosing Party (including any
     intellectual property rights granted hereunder). However, except for the
     licenses expressly granted under this Section 8, neither this Agreement nor
     any disclosure made hereunder grants any license to either Party under any
     patents or copyrights of the other Party.

     f)  Each Party shall cooperate with the other Party, at such other Party's
         expense, in registering or renewing copyrights or patent rights for
         Materials of which the ownership by the other Party is identified in
         this Section 8.

9.0  Confidentiality/Data Security 

9.1  Confidential Information 

     ISSC and ADVO each acknowledge that the other possesses and will continue
     to possess information that has been created, discovered, developed by or
     provided to it by a third party and in which property rights have been
     assigned or otherwise conveyed to it, which information has commercial
     value in its business and is not in the public domain. Except as otherwise
     specifically provided by the Parties, "Confidential Information" shall
     mean:

     a)  all information marked or otherwise identified as confidential (whether
         or not specifically enumerated in this Section 9), restricted, or
         proprietary by either Party; and

     b)  ADVO's customer lists, customer information, account information, and
         information regarding business planning and operations of ADVO and
         ADVO's administrative, financial or marketing activities.

9.2  Obligations 

     a)  ISSC and ADVO will protect Confidential Information residing on the
         system in accordance with the responsibilities set forth in Schedule L.

     b)  With respect to all other Confidential Information (e.g., hardcopy, E-
         Mail, fax) provided by one Party to the other, each will use the same
         care to prevent disclosing to third parties such Confidential
         Information of the other as it employs to avoid disclosure, publication
         or dissemination of its own information of a similar nature.

     c)  Notwithstanding the foregoing, the Parties may disclose such
         information to subcontractors involved in providing Services under this
         Agreement, or to others with a reasonable need to know, where:

         1)   such disclosure is necessary to permit the subcontractor to
              perform its duties hereunder;
<PAGE>
 
         2)   the disclosing Party assumes full responsibility for the acts or
              omissions of its subcontractor, no less than if the acts or
              omissions were those of the disclosing Party; and

         3)   pursuant to a mutually satisfactory confidentiality agreement.

     d)  Without limiting the generality of the foregoing, neither Party will
         publicly disclose the terms of this Agreement, except to the extent
         permitted by Section 9.3 and Section 15, without the prior written
         consent of the other. Furthermore, neither ISSC nor ADVO will:

         1)   make any use of the Confidential Information of the other except
              as contemplated by this Agreement;

         2)   acquire any right in or assert any lien against the Confidential
              Information of the other; or

         3)   refuse to promptly return, provide a copy of or destroy such
              Confidential Information upon the request of the other Party;

     provided, however, that the employees of each Party during the Term may
     further develop their general knowledge, skills and experience. The
     subsequent use by such employees of such general knowledge, skills and
     expertise in the ordinary course of business does not constitute a breach
     of this Agreement provided it does not infringe any intellectual property
     rights of the disclosing party.

     e)  These obligations shall apply during the Term and for a period of five
         years thereafter.

9.3  Exclusions 

     Notwithstanding the foregoing, this Section will not apply to any
     information which ISSC or ADVO can demonstrate was:
     
     a)  at the time of disclosure to it, in the public domain (provided however
         that any compilation of information in the public domain shall not
         itself per se be considered to be in the public domain);

     b)  after disclosure to it, published or otherwise becomes part of the
         public domain through no fault of the receiving Party;

     c)  in the possession of the receiving Party at the time of disclosure to
         it;
     
     d)  received after disclosure to it from a third party who had a lawful
         right to disclose such information to it; or

     e)  independently developed by the receiving Party without reference to
         Confidential Information of the furnishing Party.
<PAGE>
 
     Further, either Party may disclose Confidential Information of the other to
     the extent required by law or order of a court or governmental agency;
     provided, however, that the recipient of such Confidential Information must
     give the discloser prompt notice and make a reasonable effort to obtain a
     protective order or otherwise protect the confidentiality of such
     information, all at the discloser's cost and expense. It is understood that
     the receipt of Confidential Information under this Agreement will not limit
     or restrict assignment or reassignment of employees of ISSC and ADVO within
     or between the respective Parties and their Affiliates.

9.4  Loss of Confidential Information 

     In the event of any disclosure or loss of Confidential Information, the
     receiving Party will notify the furnishing Party immediately.

9.5  Limitation 

     ISSC will not be responsible for corruption, loss or mistransmission of
     data or for the security of data during transmission via public
     telecommunications facilities, provided ISSC has performed its obligations
     under this Agreement with respect to such data.

10.0 Termination 

10.1 Termination for Convenience

     Subject to the other provisions of this Agreement, ADVO may terminate this
     Agreement beginning three years after the Commencement Date upon at least
     180 days prior written notice to ISSC. If ADVO terminates this Agreement
     prior to the expiration of the Term, other than as specified in Section
     10.2, ADVO agrees to pay ISSC on the effective date of the termination, the
     Termination Charge, as specified in the Supplement, which the Parties agree
     is ADVO's sole and exclusive liability for such termination. Any
     termination charge will be prorated according to the following formula:

      [{(A-B)  / 12 months}  x  C] + B = Prorated Termination

                                                          Charge.

     where:

     A  =  the Termination Charge specified in the Supplement for the year in
     which termination is effective;

     B  =  the Termination Charge specified in the Supplement for the year after
     the year in which termination is effective; and

<PAGE>
 
     C =   the number of months remaining during the year in which termination
     is effective.

10.2 Termination for Cause 

     Upon written notice, either Party may terminate this Agreement, or to the
     extent reasonably practicable a portion thereof, without charge to the
     terminating Party, in the event of a material breach by the other. However,
     the Party seeking termination will provide the other Party with sufficient,
     reasonable written prior notice of such material breach and the opportunity
     to cure same, as follows:

     a)  in the event of a failure to pay any amount due and payable under this
         Agreement when due, at least thirty (30) days in the first instance of
         such failure and ten (10) days in any subsequent instance of such
         failure within any 12 month period; and

     b)  in the event of any other material breach, at least 45 days in the
         first instance of such failure and thirty (30) days in any subsequent
         instance of such failure within any twelve month period.

     If the nature of any first occurrence in any twelve month period of any
     nonmonetary breach is such that it would be unreasonable to expect a cure
     within a 45 day period, the breaching Party shall be given an additional 15
     days to cure such breach. In the event the material breach is not cured
     within the periods specified above after delivery of the notice, the
     nonbreaching Party may terminate this Agreement, which termination shall be
     in writing, as of a date specified in such notice of termination. The
     terminating Party shall have all rights and remedies generally afforded by
     law or equity, subject to the limitations expressed in this Agreement.

10.3 Extension of Services 

     Except in the case of a termination of this Agreement due to a material
     breach by ADVO, ADVO may once request and ISSC will extend the provision of
     Services for a period not to exceed 180 days beyond the effective date of
     termination or expiration. Such request must be in the form of a written
     notice received by ISSC not less than 60 days prior to the effective date
     of termination or expiration of the Agreement.

     ADVO will reimburse ISSC for all additional expenses, if any, incurred by
     ISSC as a result of ISSC's provision of such extended Services from the
     effective date of Termination which are not otherwise covered by the Annual
     Services Charge, ARCs or other charging methodology described herein.

10.4 Other Rights Upon Termination 

<PAGE>
 
     Provided ADVO has not materially breached its obligations under this
     Agreement:

     a)  ADVO may request to purchase and ISSC may consider to sell, at its
         reasonable discretion, the ISSC-owned machines then currently being
         used by ISSC on a dedicated basis to perform the Services at fair
         market value, as determined by a mutually agreed upon appraisal. ADVO
         shall be responsible for any taxes associated with the purchase of, as
         well as the costs for any appraisals of, such equipment.

     b)  For Software proprietary to ISSC or its Affiliates (if necessary to be
         used to provide the Services) and not otherwise owned by or licensed to
         ADVO in accordance with Section 8 and not generally commercially
         available:

         1)   ISSC will provide a license to ADVO, for its internal use only,
              upon terms and prices to be mutually agreed upon by the Parties
              that are comparable to, and in the case of prices, that do not
              exceed, the prices and terms for similar commercial software. If
              such similar commercial software does not exist, such license will
              be provided at a price intended to generally compensate ISSC for
              its investment in such software as such compensation would be
              implemented in its commercial products; or

         2)   at ADVO's option, ISSC will recommend a mutually agreeable
              commercially available substitute to perform the same function.

     c)  ISSC will use reasonable efforts to obtain the right to transfer all
         Software licenses used in support of ADVO to ADVO at the termination or
         expiration of the Term without charge. If this is not possible, ISSC
         will notify ADVO prior to obtaining such Software and subject to ADVO's
         acceptance of any applicable vendor terms and conditions and payment by
         ADVO of any transfer fee, license fee or other charges imposed by such
         vendor:

         1)   with respect to generally commercially available Software, if ISSC
              has licensed or purchased and is using any such Software solely
              for providing the Services to ADVO at the date of expiration or
              termination, ISSC will transfer the requested Software to ADVO and
              ADVO will reimburse ISSC for initial license or purchase charges
              for such Software in an amount equal to the remaining unamortized
              cost of such Software, if any, depreciated over a five year life;

         2)   with respect to generally commercially available Software, if ISSC
              has licensed or purchased and is using any such Software for
              providing the Services to ADVO and other ISSC customers in a
              shared environment at the date of expiration or termination, ISSC
              will assist ADVO in obtaining licenses for such Software; and

         3)   ISSC will transfer or assign to ADVO or its designee, upon ADVO's
              request, on mutually acceptable terms and conditions, any
<PAGE>
 
              contracts applicable solely to the Services being provided to ADVO
              (i.e., maintenance, disaster recovery services and other necessary
              third party services with the exception of subcontractor services)
              then being used by ISSC to perform the Services.

     d)  ISSC will further use its reasonable efforts, where necessary or
         appropriate, to obtain new Software licenses in ADVO's name and through
         the Change Management Procedures, during the Term.

     e)  ISSC will provide Services Transfer Assistance pursuant to Section 6.8.

11.0 Liability

11.1 General Intent 

     Each Party's and each of its subcontractor's entire liability to the other
     Party and their exclusive remedies are set forth in this Section and
     Section 13. Subject to the specific provisions of this Section, it is the
     intent of the Parties that each Party will be liable to the other Party for
     any damages incurred by the nonbreaching Party as a result of the breaching
     Party's failure to perform its obligations in the manner required by this
     Agreement.

11.2 Damages 

     a)  Each Party's and each of its subcontractor's entire liability for
         actual, direct damages resulting from such party's performance or
         nonperformance under this Agreement, regardless of the form of action,
         and whether in contract, tort (including, without limitation,
         negligence), warranty or other legal or equitable grounds, will be
         limited in the aggregate for all claims to an amount equal to:

         1)   the amount actually paid by ADVO to ISSC for the Services during
              the six months prior to the occurrence of the first event which is
              the subject of the first claim; or

         2)   in the case where less than six months of the Term have elapsed at
              the time of an event which is the subject of a claim, the actual
              charges during the first six months of the Term.

     b)  This limitation will not apply to:

         1)   any obligation or failure by ADVO to pay any amounts due or past
              due and owing to ISSC pursuant to the terms of this Agreement;

         2)   Losses by either Party for bodily injury or damage to real
              property or tangible personal property, as described in Section
              13.3;

         3)   Losses incurred by a Party caused by or arising out of the 
<PAGE>
 
              inaccuracy or untruthfulness of the representations and warranties
              of the other Party contained in this Agreement;

         4)   either Party's obligation to indemnify the other for patent and
              copyright infringement Losses and Losses relating to tax

              and (c), respectively; and

         5)   Losses incurred by either Party arising under the indemnity by the
              other Party under Section 13.1(d) and (e) and 13.2(d).

     c)  In no event will either Party have any liability whether based on
         contract, tort (including, without limitation, negligence), warranty or
         any other legal or equitable grounds, for any loss of interest, profit
         or revenue by the other Party or for any consequential, indirect,
         incidental, special, punitive or exemplary damages suffered by the
         other Party, arising from or related to this Agreement, even if such
         Party has been advised of the possibility of such losses or damages;
         provided, however, that this clause will not prevent either Party from
         recovering amounts owed under this Agreement.

     d)  In no event will ISSC or its subcontractors be liable for any damages
         if and to the extent caused by ADVO's failure to perform its
         responsibilities, nor shall ADVO be liable for any damages if and to
         the extent caused by any failure to perform by ISSC or its
         subcontractors.

              performing the Services for ADVO at the Facilities at ADVO's
              request; and

         2)   the Facilities are in compliance with all material applicable
              federal, state and local laws governing the storage, existence,
              discharge and handling of Hazardous Materials. ADVO is responsible
              for any waste generated at its Facilities and, if applicable, the
              proper manifest of any hazardous waste to appropriate disposal
              sites under ADVO's name and identification number.

     b)  "Hazardous Materials" means:

         1)   any "hazardous substance" as defined in the Comprehensive
              Environmental Response, Compensation and Liability Act of 1980, as
              amended from time to time (42 U.S.C. 9601 et seq.) and the
              regulations promulgated thereunder;

         2)   any asbestos or asbestos-containing materials; 

         3)   petroleum, crude oil or any fraction thereof, natural gas or
              synthetic gas used for fuel; and

         4)   any additional substances or materials which at such time are
              classified or considered to be hazardous or toxic under the laws
              of the state wherein the Facilities are located.

     c)  In the event that Hazardous Materials are present at the Facilities
         during the Term of this Agreement, ISSC may cease the performance of
         that portion of the Services affected by their presence if, in the
         reasonable judgment of ISSC, ISSC's ability to perform such portion of
         the Services safely and properly is adversely impacted by the presence
         of such Hazardous Materials. ADVO shall be responsible for causing any
         violation of federal, state or local law with respect to the presence
         of such Hazardous Materials to be remedied, it being understood that
         matters relating to the investigation, detection, abatement and
         remediation of any Hazardous Materials present at the Facilities are
         not within the scope of this Agreement and that ISSC shall not be
         liable or responsible for any expense incurred by ADVO in this
         connection, unless ADVO's investigation reveals that the presence of
         the Hazardous Materials was caused by the conduct of an ISSC employee,
         invitee, or subcontractor. In such event, the limitations of this
         paragraph will not apply.

12.4 Noninfringement 

     The Parties represent and warrant that they will perform their
     responsibilities under this Agreement in a manner that does not infringe,

     c)  this Agreement has been duly executed and delivered by such Party and

13.4 Subrogation

     In the event that an Indemnifying Party shall be obligated to indemnify an
     Indemnified Party pursuant to Sections 13.1, 13.2 or 13.3, the Indemnifying
     Party shall, upon payment of such indemnity in full, be subrogated to all
     rights of the Indemnified Party with respect to the claims and defenses to
     which such indemnification relates.

13.5 Exclusive Remedy 

     The indemnification rights of each Indemnified Party pursuant to Sections
     13.1, 13.2 or 13.3, together with any equitable remedies, shall be the
     exclusive remedies of such Indemnified Party with respect to the claims to
     which such indemnification directly relates.

13.6 Indemnification Procedures 

     a)  If any civil, criminal, administrative or investigative action or
         proceeding (any of the above being a "Claim") is commenced against any
         Party entitled to indemnification under Sections 13.1, 13.2 or 13.3 (an
         "Indemnified Party") written notice thereof shall be given to the Party
         that is obligated to provide indemnification under such Sections (the
         "Indemnifying Party") as promptly as practicable. After such notice, if
         the Indemnifying Party shall acknowledge in writing to such Indemnified
         Party that this Agreement applies with respect to such Claim, then the
         Indemnifying Party shall be entitled, if it so elects, in a written
         notice delivered to the Indemnified Party not fewer than 10 days prior
         to the date on which a response to such Claim is due, to take control
         of the defense and investigation of such Claim and to employ and engage
         attorneys to handle and defend the same, at the Indemnifying Party's
         sole cost and expense after providing the Indemnified Party advance
         written notice of the counsel to be retained and allowing for
         reasonable comment. The Indemnified Party shall cooperate in all
         reasonable respects with the Indemnifying Party and its attorneys in
         the investigation, trial and defense of such Claim and any appeal
         arising therefrom; provided, however, that the Indemnified Party may,
         at its own cost and expense, participate, through its attorneys or
         otherwise, in such investigation, trial and defense of such Claim and
         any appeal arising therefrom. No settlement of a Claim that involves a
         remedy other than the payment of money by the Indemnifying Party
         without contribution by the Indemnified Party shall be entered into
         without the consent of the Indemnified Party, which consent will not be
         unreasonably withheld.

     b)  After notice by the Indemnifying Party to the Indemnified Party of its
         election to assume full control of the defense of any such Claim, the
         Indemnifying Party shall not be liable to the Indemnified Party for any
         legal expenses incurred thereafter by such Indemnified Party in
         connection with the defense of that Claim. If the Indemnifying Party
         does not assume full control over the defense of a Claim subject to
         such defense as provided in this Section 13.6, the Indemnifying Party
         may participate in such defense, at its sole cost and expense, and the
         Indemnified Party shall have the right to defend the Claim in such
         manner as 


<PAGE>
 
         it may deem appropriate, at the cost and expense of the Indemnifying
         Party.
         
14.0 Insurance and Risk of Loss 

14.1 Insurance 

     When this Agreement requires performance by ISSC's or ADVO's employees or
     subcontractors on the other Party's premises, the performing Party shall
     carry and maintain Worker's Compensation Insurance, including Employers
     Liability Insurance, covering its employees and subcontractors engaged in
     such performance in amounts no less than required by law in the applicable
     location.

14.2 Risk of Loss 

     ADVO is responsible for risk of loss of, or damage to, Machines located on
     ADVO's premises and any loss of or damage to Software in ADVO's possession
     at the time of such loss or damage. ISSC is responsible for risk of loss
     of, or damage to, Machines located on ISSC's premises and any loss of or
     damage to Software in ISSC's possession at the time of such loss or damage.
     The foregoing shall not be interpreted to relieve ISSC of any of its
     express obligations otherwise set forth in this Agreement.

15.0 Publicity 

     Each Party will submit to the other all advertising, written sales
     promotion, press releases and other publicity matters relating to this
     Agreement in which the other Party's name or mark is mentioned or language
     from which the connection of said name or mark may be inferred or implied,
     and will not publish or use such advertising, sales promotion, press
     releases, or publicity matters without prior written approval of the other
     Party. However, either Party may include the other Party's name and a
     factual description of the work performed under this Agreement on employee
     bulletin boards, in its list of references and in the experience section of
     proposals to third parties, in internal business planning documents and in
     its annual report to stockholders, and whenever required by reason of
     legal, accounting or regulatory requirements.

16.0 Review Committee and Dispute Resolution 

16.1 Joint Advisory Committee 

     ISSC and ADVO agree to create a Joint Advisory Committee consisting of four
     people of the following titles from each Party:

     ISSC

         1)   Director, ISSC Media Industry 
<PAGE>
 
         2)   Project Delivery Executive, ISSC Media Industry

         3)   ISSC Project Executive 

         ADVO

         1)   Vice President and Chief Information Officer

         2)   ADVO Finance Director

         3)   ADVO Project Executive 

     The Joint Advisory Committee will:

     a)  conduct quarterly reviews of the progress on projects; 

     b)  annually review the operating and strategic plans prepared by the
         Project Executives;

     c)  review, on an annual basis, performance objectives and measurements;

     d)  provide advice and direction on technology changes; and 

     e)  resolve disputes between the Parties. 

16.2 Dispute Resolution 

     a)  Any dispute between the Parties either with respect to the
         interpretation of any provision of this Agreement or with respect to
         the performance by ISSC or by ADVO hereunder shall be resolved as
         specified in this Section 16.2.

         1)   Upon the written request of either Party, each of the Parties will
              appoint a designated representative who does not devote
              substantially all of his or her time to performance under this
              Agreement, whose task it will be to meet for the purpose of
              endeavoring to resolve such dispute.

         2)   The designated representatives shall meet as often as necessary to
              gather and furnish to the other all information with respect to
              the matter in issue which is appropriate and germane in connection
              with its resolution.

         3)   Such representatives shall discuss the problem and negotiate in
              good faith in an effort to resolve the dispute without the
              necessity of any formal proceeding relating thereto.

         4)   During the course of such negotiation, all reasonable requests
              made by one Party to the other for nonprivileged information
              reasonably related to this Agreement, will be honored in order
              that each of the Parties may be fully advised of the other's
              position.
<PAGE>
 
         5)   The specific format for such discussions will be left to the
              discretion of the designated representatives but may include the
              preparation of agreed upon statements of fact or written
              statements of position furnished to the other Party.

     b)  If the designated representatives cannot resolve the dispute, then the
         dispute shall be escalated to the President of ADVO and the President
         of ISSC, for their review and resolution. If the dispute cannot be
         resolved by such officers, then the Parties may initiate formal
         proceedings; however, formal proceedings for the judicial resolution of
         any such dispute may not be commenced until the earlier of:

         1)   the designated representatives concluding in good faith that
              amicable resolution through continued negotiation of the matter in
              issue does not appear likely; or

         2)   30 days after the initial request to negotiate such dispute; or 

         3)   30 days before the statute of limitations governing any cause of
              action relating to such dispute would expire.

16.3 Continued Performance 

     Except where clearly prevented by the area in dispute, both Parties agree
     to continue performing their respective obligations under this Agreement
     while the dispute is being resolved unless and until such obligations are
     terminated or expire in accordance with the provisions hereof.

17.0 General 

17.1 Control of Services 

     a)  This Agreement shall not be construed as constituting either Party as
         partner of the other or to create any other form of legal association
         that would impose liability upon one Party for the act or failure to
         act of the other or as providing either Party with the right, power or
         authority (express or implied) to create any duty or obligation of the
         other Party.

     b)  Each Party shall be responsible for the management, direction and
         control of its employees and such employees shall not be employees of
         the other Party.

     c)  Except where this Agreement expressly provides that ISSC will perform
         certain identified Services as agent for ADVO, the Services will be
         under the control, management and supervision of ISSC.

17.2 Right to Perform Services for Others 

     Each Party recognizes that ISSC personnel providing Services to ADVO under
     this Agreement may perform similar services for
<PAGE>
 
     others and this Agreement shall not prevent ISSC from using the personnel
     and equipment provided to ADVO under this Agreement for such purposes. ISSC
     may perform its obligations through its subsidiaries, Affiliates or through
     the use of ISSC-selected independent contractors; provided, however, that:

     a)  ISSC will obtain the advance approval of ADVO (which approval shall not
         be unreasonably withheld or delayed) prior to bringing any
         subcontractor on ADVO premises;

     b)  ISSC will obtain the advance approval of ADVO (which approval shall not
         be unreasonably withheld or delayed) prior to subcontracting any
         Services requiring a direct interface between the subcontractor and
         ADVO; and

     c)  ISSC will not be relieved of any of its obligations under this
         Agreement by use of any such subsidiaries, Affiliates or
         subcontractors.

         For the purposes of this Section, any subcontractors listed on Schedule
         K shall be considered to have been approved by ADVO.

17.3 Scope of Services 

     The Services provided under this Agreement are for Machines and facilities
     located within the United States, Puerto Rico or Guam.

17.4 Amendments and Revisions 

     No changes or modifications to this Agreement, its Supplement and Schedules
     may be made orally, but only by a written amendment or revision signed by
     both Parties.

     Any terms and conditions varying from this Agreement, its Supplement and
     Schedules on any order or written notification from either Party are void.

17.5 Force Majeure 

     a)  Neither Party shall be liable for any default or delay in the
         performance of its obligations hereunder:

         1)   if and to the extent such default or delay is caused, directly or
              indirectly, by fire, flood, earthquake, elements of nature or acts
              of God, acts of war, terrorism, riots, civil disorders, rebellions
              or revolutions in the United States, strikes, lockouts, or labor
              difficulties, or any other similar cause beyond the reasonable
              control of such Party; or

         2)   provided such default or delay could not have been prevented by
              reasonable precautions and cannot reasonably be circumvented by
              the nonperforming Party through the use of alternate sources, 
              work-around plans or other means,
<PAGE>
 
              (individually, each being a "Force Majeure Event"). 

     b)  In such event, the nonperforming Party will be excused from any further
         performance or observance of the obligation(s) so affected for as long
         as such circumstances prevail and such Party continues to use
         commercially reasonable efforts to recommence performance or observance
         whenever and to whatever extent possible without delay. Any Party so
         delayed in its performance will immediately notify the other by
         telephone (to be confirmed in writing within five days of the inception
         of such delay) and describe at a reasonable level of detail the
         circumstances causing such delay.

     c)  If any Force Majeure Event substantially prevents, hinders, or delays
         perfor-mance of the Services necessary for the performance of ADVO's
         critical functions for more than 30 consecutive days, then at ADVO's
         option:

         1)   ADVO may procure such Services from an alternate source and ISSC
              will be liable for payment for such Services in excess of ISSC's
              charges under this Agreement for up to 180 days; or

         2)   this Agreement will terminate as of a date specified by ADVO in a
              written notice of termination to ISSC and ADVO will pay ISSC any
              unrecovered start-up costs, anticipated profit prorated to the
              date of termination, and any reasonable out-of-pocket expenses
              associated with ramp down transition costs, all subject to
              independent audit.

     d)  This Section 17.5 does not limit or otherwise affect ISSC's obligation
         to provide disaster recovery services in accordance with Schedule G;
         provided, however, that such Force Majeure Event does not also prevent
         ISSC's provision of the Services from the recovery center(s).

     e)  With the exception of charges for the directly affected portion of
         Services, this Section 17.5 does not limit or otherwise relieve ADVO's
         obligation to pay any monies due ISSC under the terms of this
         Agreement.

17.6 Nonperformance 

     To the extent any Party is not able to perform its nonmonetary obligations
     under this Agreement as a result of the other Party's failure to perform
     its obligations under this Agreement, such nonperformance shall be excused.

17.7 Remarketing 

     ADVO may not remarket all or any portion of the Services provided under
     this Agreement, or make all or any portion of the Services available to any
     party other than ADVO or its Affiliates, without the prior written consent
     of ISSC.

      No waiver of any breach of any provision of this Agreement shall
      constitute a waiver of any prior, concurrent or subsequent breach of the
      same or any other provisions hereof.

17.9  Severability 

      If any provision of this Agreement shall be held to be invalid, illegal or
      unenforceable, the validity, legality and enforceability of the remaining
      provisions shall not in any way be affected or impaired thereby, and such
      provision shall be deemed to be restated to reflect the original
      intentions of the Parties as nearly as possible in accordance with
      applicable law(s).

17.10 Limitations Period upon Termination 

      Neither Party may bring an action, regardless of form, arising out of this

      discovered.

17.11 Counterparts

17.12 Governing Law 

      This Agreement shall be governed by the laws of the State of New York as
      such laws are applied to contracts which are entered into and performed
      entirely within the State of New York. The Parties agree that the
      exclusive jurisdiction for any dispute arising hereunder shall be in the
      federal district court with appropriate jurisdiction in the State of
      Connecticut, or if there is no jurisdiction in federal district court,
      then in the state court in Connecticut with appropriate jurisdiction.

17.13 Survival, Binding Nature and Assignment 

      Any terms of this Agreement which by their nature extend beyond its
      expiration or termination remain in effect until fulfilled. This Agreement
      will be binding on the Parties and their respective successors and
      permitted assigns. For purposes of this Agreement, a change in Control of
      a Party or a sale of all or substantially all of the assets of a Party
      shall be deemed an assignment of this Agreement.

      Neither Party may, or will have the power to, assign this Agreement
      without the prior written consent of the other, except that either Party
      may assign its rights and obligations under this Agreement, without the
      approval of the other, to an

      Affiliate or to any party acquiring all or substantially all of ADVO's
      assets which expressly assumes such Party's obligations and
      responsibilities hereunder, provided that the assigning Party remains
      fully liable for and shall not be relieved from the full performance of
      all obligations under this Agreement.

      Any attempted assignment that does not comply with the terms of this
      Section shall be null and void. Any Party assigning its rights or
      obligations to an Affiliate in accordance with this Agreement shall,
      within three business days of such assignment, provide written notice
      thereof to the other Party together with a copy of the assignment
      document.
