RE:     Klamath Falls Casino
        Inland Casino Corp.
        Chiloquin, Oregon

We are pleased to present this proposal for professional civil engineering
consulting services.

A.      Pricing Description:

        Proposed gaming facility for the Klamath Tribes, located south of the
        City of Chiloquin in Klamath County, Oregon. The development will be on
        approximately 20 acres of the 42.31 acres available. The building is
        approximately 19,000sf with parking area of 2.6 acres, as shown on
        drawings S-1 and K-1 by your office, dated 10/17/96.

B.      Scope of Work:

        B.1     Contract Document Phase

                1.      Site plan and grading plan

                        Prepare plan indicating location of parking lots,
                        curbing  and sidewalks, utility location and
                        coordination, earthwork analysis (cut/fill), details.

                2.      Stormwater drainings plan

                        Conduct on-site and off-site analysis, design of
                        stormwater conveyance system, and water quality
                        assurance. It is understood that detention is not
                        required, but that the probable water quality solution
                        will be drainfields (also indicated in the Environmental
                        Assessment, by WEST, Inc., dated 7/27/96). Methodology
                        for hydrologic design will be SBUM. Other anticipated
                        features include connection to roof drains and an
                        oil/water separator preceding the drainfield. Work will
                        comply with standard requirements of E.P.A. and the
                        Oregon Department of Environmental Quality for NPDES
                        permit. It is assumed that the system will be gravity
                        flow; no pump design is anticipated.

                3.      Temporary erosion and sediment control plan

                        As in Item B.1.2 requirements for the NPDES permit will
                        be met. Control measures may include a temporary
                        sediment pond, fabric fencing, other intercept measures,
                        construction sequencing, construction entrance and
                        setting clearing limits.
