2.       SCHEDULE, STATEMENT OF WORK AND DELIVERABLES

2.1      TASKS AND SCHEDULE

Reference Section 4 and 5 in its entirety of the CSR [   ] Proposal for the Work
Breakdown Structure and Schedule to address this section of this Schedule No.
23-07-97.

2.2      ASSUMPTIONS

The project description, schedules, and deliverables were developed based on the
assumptions provided in Sections 8 of the CSR [             ] Proposal. If these
assumptions are not valid, changes to the schedule, deliverables, and cost of
the CSR [           ] project may be required.

         1.       BOSS access for new APIs can be provided through existing IMS
                  capability with no updates to the BMP process. If IMS
                  capability for these transactions does not exist, U S WEST
                  will add the necessary IMS transactions.

         2.       Based on past Fetch 'N Stuff experience, we assume that CARS
                  access through screen scraping will be necessary (worst case
                  assumption). Capabilities are not supported by COBOL through
                  the BMP.

         3.       The schedule is based on a project start date of 12/1/97.
                  Delays in this start date will impact the project completion
                  date.

         4.       The work estimates are based on Carnegie Group Methodology and
                  past experience. Carnegie Group will continuously monitor the
                  project status and notify U S WEST of any issues or risk
                  situations which may impact the delivery date.

         5.       Carnegie Group has timely access to required U S WEST
                  personnel (e.g. subject matter experts).

         6.       U S WEST provides a project sponsor to act as the liaison
                  between the U S WEST and Carnegie Group. This does not require
                  that U S WEST handle all Interconnect Engineering interactions
                  but that appropriate personnel be provided to support these
                  activities.

         7.       All development will be done on Carnegie Group premises and
                  facilities. Intermediate and final software products will be
                  moved to U S WEST facilities as required.

         8.       Any delays outlined in the Dependencies may impact the
                  delivery dates.

         9.       Change requests to the requirements outlined in this proposal
                  must be defined by U S WEST for analysis by Carnegie Group to
                  provide estimates, costs, and impact on current deliverables.
                  Signed approval by both parties is required prior to
                  implementation of any change request.

         10.      The primary point of contact will be Patti Jansen who will
                  designate a back-up contact when unavailable.
