This Letter Agreement dated March 25, 1997 is in regard to Development

These additional efforts require the addition of one (1) CGI resource who is
working as a Manager to assist in the Repair area, more specifically to provide
client management needed to make Repair successful within the Call Handling
architecture for an estimated period of six (6) months beginning March 24,
1997.

Engineer II ("SE2") to provide consulting services including assessing the
overall network performance and making recommendations for architecture design
and detailed design improvements within the Call Handling /FES&R system, under
U S WEST's direction. These consulting services at the SE2 level are estimated
to be provided over a period of ten (10) weeks between the period of April 1,
1997 and July 31, 1997.

This Amendment includes additional funding in the amount of $[     ] to the
original work scoped in Development Agreement 35-001-97. The Projected Cost and
Payment for the Project in Article 5 of the Development Agreement have been
increased by $[     ] to $[     ].

                           EXHIBIT 2 - ESTIMATED COST

COST OVERVIEW

The total cost of the work net of discounts is estimated at $[     ]
based on expected time and material expenses, which represents an
increase of $[     ] above the original funding approved for Call
Handling - 1997 of $[     ]. No travel is anticipated for this project.
Should travel be required, U S WEST agrees to pay CGI travel expenses
for all pre-approved trips.

Work will be provided on a time and materials basis. The cost estimate and
applicable discount breakouts being extended are as shown below. The [ ]%
Alliance Discount has been extended pursuant to the GLA extension executed
between U S WEST and CGI in March, 1997. The [ ]% Facilities Discount (includes
[ ]% computer and [ ]% building discount) is extended under the assumption that
all work will be performed at U S WEST facilities for this project. Work
requiring platforms and software outside of this environment will be requested
by U S WEST. It is planned that U S WEST will provide availability to the
nonstandard items to CGI for the duration of the project should any be
required.  CGI has also extended the applicable Volume Discount of [ ]%.

U S WEST may, at its discretion, close the project or the involvement of CGI
resources by providing a written notice to the CGI Program Manager. If such an
eventuality occurs, the respective resources will be given a ramp down period
of [ ] weeks to find other work. Upon completion of the [ ] week ramp down
period, U S WEST will be obligated to CGI for the time and materials expended
up to and including the [ ] week ramp down.
