July 3, 2000 Bill McKell President Horizon Personal Communications 68 East Main Street Chillicothe, OH 45601 Bill: According to our most recent Build-Out Compliance Report dated 3-31-00, Horizon is materially in compliance with respect to its build-out commitment in Exhibit 2.1. There are, however, six BTA's where Horizon's covered pop numbers fall short of the exact build-out requirement. BTA Current Covered Pops Shortfall Roanoke -6,556 Fairmont -5,574 Martinsville -3,169 Lynchburg -2,707 Staunton-Waynesboro -536 Danville -31 At this time Sprint PCS does not consider these shortfalls to be a material breach, however, we do expect that Horizon will take steps to meet 100% of its build-out commitment in these BTAs by December 31, 2000. In reviewing your future build-out plans and the resulting covered pops for these BTA's, it appears that you will be in full compliance with Exhibit 2.1 in these BTA's well before that date. Also, in reviewing your overall build-out plans, it appears that those plans are consistent with Exhibit 2.1. Assuming Horizon is able to fulfill all aspects of those build-out plans, Horizon's build-out will be fully compliant with Exhibit 2.1 in all markets. Sincerely, /s/ Scott Fisher Scott Fisher Director Affiliate Relations SF/ah
