Exhibit 10.15


                              Letter of Agreement

This letter of agreement specifies the major points of agreement between Eastern
Washington University, Davis Communications, Inc., and Optimal Systems
Integrators, Inc. under which Davis Communications, Inc. and Optimal Systems
Integrators, Inc. will deliver Internet services to 900 dormitory rooms on the
Eastern Washington University campus.  This Letter of Agreement will become an
attachment to and will be incorporated into the Agreement for Cable Television
Services, entered into between Davis Communications, Inc. and Eastern Washington
University, dated October 1, 1994.

Basic Terms:

     The term of the agreement will be three years with service beginning on or
     before September 15, 1997.  However, if Eastern Washington University
     determines that the service has not been satisfactorily provided during
     year one, the University may cancel subject to a specified cancellation fee
     of $2.50 per room per month for year one (nine months).

     The goal of the service is to provide students with download access
     comparable to the T1-served LAN-based systems as are available to the
     students in the University Lab and Classroom systems.

     Davis Communications, Inc. and Optimal Systems Integrators, Inc. will
     provide high-speed Internet services via cable TV distribution to 900
     dormitory rooms in the following five (5) buildings:  Pierce, Morrison,
     Dressler, Streeter, and Dryden.  High-speed Internet access is defined as
     download speeds from local services of not less than 256 Kilobits/s
     provided that 20% or less of all rooms are concurrently accessing the
     Internet.  Download speeds from specific non-local Internet sites are
     understood to be beyond the control of Davis Communications, Inc. and
     Optimal Systems Integrators, Inc.  It is also understood that the service
     is asymmetrical and is not appropriate for hosting of student-operated web
     sites or other Internet publishing activities.

     Davis Communications, Inc. will bill the University quarterly in arrears,
     based on 900 rooms, as such:

          .    During year one, $7.50 per room per month for nine months (three
               quarters) ($60,750).

          .    During years two and three, $10.00 per room per month for nine
               months (three quarters) ($81,000/yr.).


          .    If the service is cancelled prior to the onset of year two, an
               additional $2.50 per room per month for year one service is due
               and payable at service cancellation ($20,250).

     The University will pay the City of Cheney franchise tax and other
     applicable taxes.

     Davis Communications, Inc. and Optimal Systems Integrators, Inc. are
     responsible for the reliable operation of the electronic equipment, the
     wiring, and the other components accessible to them that are necessary to
     the provision of Internet access to the University's dormitory.  Neither
     Davis Communications, Inc. nor Optimal Systems Integrators, Inc. will be
     held responsible for short-term service outages resulting from common
     carrier failures or error conditions existing "out in the Internet" or
     failure of equipment completely outside the control of either party.

     Davis Communications, Inc. and Optimal Systems Integrators, Inc. are not
     liable for any consequential damages due to any service outage.

     Davis Communications, Inc. and Optimal Systems Integrators, Inc. are
     responsible for user-level customer service concerning the operation and
