These stations have a geographic service area covering the Arlington VA/Hemdon VA area. Intel has requested Clearwire‘s consent to use of Channels C123, D123 in the Arlington VA/Herndon VA area described in Exhibit A (the "Spectrum") to conduct WiMax testing from March 15, 2010 through March 15, 2011. Intel‘s use of the Clearwire system will be coordinated and under the control of Clearwire personnel. By its signature below, Clearwire hereby consents to Intel‘s use of the Spectrum on a temporary basis for WiMax testing described in more detail in Exhibit B. Intel agrees to operate on the Spectrum at its sole cost and expensein accordance with the rules and regulations of the Federal Communications Commission, and to take all necessary steps to cause no interference to any operations and to protect and preserve the status of the licenses associated with the Spectrum. Intel will obtain an Experimental Authorization (currently WDIXZV) for use of the Spectrum and pay all reasonable out of pocket costs incurred by Clearwite to obtain consents from the EBS licensees, in an amount not to exceed $1000 per licensee. Intelfurther agrees to indemnify Clearwire against any damages caused by their temporary operation ofthe Spectrum, including, without limitation, the payment of anyfineslevied by the FCC or other regulatory authority for any improper use of the Spectrum, such as, but not limited to, interference with other channels or Clearwire‘s commercial network. Withoutlimiting the foregoing, Intel agrees that in the event of interference, immediately upon oral or written notice (within four (4) hours in any event), it will immediately cease any use of the Spectrum, until any interference issues that might arise are resolved to Clearwire‘s satisfaction. Clearwire reservesthe rightto terminate or substitute the use of someor the entire Spectrum, with 30 days prior notice. Intel agrees to cooperateto share test plans on a confidential basis. To that end, during and upon completion ofthe WiMax testing, and in exchange for Clearwire‘s consent as described above,

Clearwire and its corporate affiliates shall have reasonable access to thetesting data and conclusions in connection with the equipment as collected by Intel, for the purpose of evaluating possible interference with the commercial network. Test information provided will be consistent in format and substance with previous information exchanged between Clearwire and Intel. Clearwire reserves the right to reasonably reject or collaborate with Intel to modify any test plans that would result in interference with Clearwire‘s commercial system.

The base stations are deployed in conductance configurations in labs, indoor DAS and picocell—like configurations, and outdoor suburban macro coverage in the Hillsboro area. Most equipment is located in the Jones Farm campus but some equipment is in the Intel Israel labs, Intel California labs, and Clearwire Portland (Bancroft) labs. Intel and Clearwire employees use the system to characterize performance, capacity, coverage, and interoperability of the system with a primary focus on the ecosystem of client devices. The RAN configuration is aligned with the Portland commercial system or with expected upcoming configurations.
