SPECTRUM AGREEMENT

This Spectrum Agreement, (the “Agreement”), is entered into by and between Google Inc., a Delaware corporation (“Google”), and Clearwire Communications LLC, a limited liability company formed under the laws of Delaware (“Customer”), and is effective as of November 28, 2008 (“Effective Date”).

1. Generally.

1.1. As described in this Agreement, Customer and Google have agreed to pursue certain opportunities relating to alternative uses of Customer’s excess 2.5GHz spectrum in the United States as set forth below. The parties have entered into this Agreement to set forth their mutual understanding of the relationship between Google and Customer with respect to alternative uses of Customer’s excess 2.5GHz spectrum in the United States.

2. Nature of spectrum collaboration.

2.1. The parties agree that Customer (and any successor, assignee, acquirer or transferee of Newco’s spectrum) intends to use its 2.5 GHz spectrum in the U.S. for managed, facilities-based communications services, utilizing mobile WiMax technology and otherwise. All such use is defined in this Agreement as “Primary Use.” Any use of Newco’s U.S. 2.5 GHz spectrum that is other than for Primary Use will be defined in this Term Sheet as “Secondary Use.”

2.2. Customer will make available to Google certain of its excess 2.5GHz spectrum in one or more markets as mutually agreed, for the experimental purposes described in Sections 2.5, 3 and 4 of this Agreement. Pursuant to Section 4, following successful completion of the trials described in Section 2.5, Customer will make its excess spectrum available across the United States for the purposes of developing Secondary Uses consistent with the uses described in this agreement.

2.3. All Secondary Use of spectrum will occur under the direction of a joint Customer/Google technology team, to be established pursuant to Section 8 of this Agreement. All Secondary Use will be subject to Customer’s approval, in accordance with all the provisions of this Agreement, and will not violate any of Customer’s contractual obligations, including spectrum leases and debt covenants, and will comply at all times with all applicable FCC rules.

2.4. At no time will Google undertake any Secondary Use of spectrum in a manner that would interfere with Customer’s Primary Use of its spectrum.

2.5. The parties agree to pursue in good faith a trial of methods whereby Customer’s excess spectrum will be made available to third parties for Secondary Uses through Google-developed or Google-sponsored technology. Such Secondary Use is to be in compliance with Section 2.4 of this Agreement

and is to be technologically feasible, from Customer’s reasonable perspective. The trial will take place as set forth in Section 4 of this Agreement.

2.6. The actual availability of excess spectrum for Secondary Uses will be reasonably determined by NewCo based on Newco’s actual or planned use of its spectrum which will vary from time to time.

2.7. Both Parties agree that metrics will be put in place to provide for technical testing of the spectrum and the technology to be used. The joint Customer/Google technology team established under Section 8 of this Agreement will develop these metrics prior to the review of technical feasibility called for in Section 2.5.

3. Use of Spectrum.

3.1. Google will undertake experimental tests of different Secondary Uses of spectrum, including, but not limited to, [*****] (as discussed below in Section 4). Such tests will be at the discretion of Google and may involve varying amounts of spectrum, including [*****].

3.2. During the term of the Spectrum Agreement, Google and Customer will engage in experimental collaborations for new services, using excess spectrum available for Secondary Use.

3.3. Customer will make reasonable efforts to support Google’s experiments to find successful ways of implementing Secondary Uses.

4. [*****].

4.1. Google will use the spectrum provided by Customer, in part, to test the concept of [*****].

4.2. [*****].

4.3. [*****].

4.4. The trial provided for in this Section 4 may begin as soon as [*****] described in Section 4.3 has been determined and approved. The parties contemplate that the trial will be undertaken over a period of [*****].

4.5. Upon successful completion of the trial contemplated by this Section 4, showing that [*****] is functioning successfully, the parties agree that Customer will work with Google to allow for Secondary Use of spectrum nationwide, using Google technology. Successful completion of the trial will include Customer’s determination that the Secondary Use results in no interference with Customer’s Primary Use and is technologically feasible.

5. Revenue.

5.1. The parties anticipate that all of the Secondary Uses to be implemented by Google will generate revenue.

5.2. The parties will share such revenue. They agree to negotiate the terms of such revenue sharing, on an equitable basis, with respect to each Secondary Use that is mutually agreed to be implemented.

5.3. In all circumstances, the parties agree that Secondary Uses of spectrum will be intended to provide Customer with an economic return that takes into account the fair value of the spectrum.

6. Term.

6.1. The initial term for this Agreement will be [*****] from the execution of the Agreement.

6.2. No later than one hundred (180) days prior to the end of the initial term, the joint Customer/Google technology team will revisit the terms of Secondary Use and the results of all technology trials or implementations that have occurred.

6.3. During the last one hundred (180) days of the initial term, the parties will determine whether to extend the term of this Agreement and, if so, on what terms and conditions. Customer’s evaluation will include a consideration as to whether Google’s Secondary Uses generate an acceptable return on Customer’s investment in spectrum as compared to alternative opportunities to generate a return.

6.4. In the event of a breach of this Agreement by either party, the non-breaching party may provide written notice to the breaching party of such breach. In the event that the breaching party does not cure such breach within thirty (30) days of receiving the notice of breach, the non-breaching party may terminate this Agreement; provided, however that if such breach relates to an action that causes or is reasonably likely to cause material interference to Customer’s Primary Use or the loss of spectrum, this Agreement will terminate immediately if the action or inaction causing the breach continues more than 24 hours follow receipt of written notice.

7. Regulatory issues.

7.1. The parties will cooperate to ensure that all Secondary Use of spectrum comply with all applicable laws and all applicable FCC rules and regulations, as well as all leases or other agreements affecting the use of Customer’s spectrum.

7.2. The parties will cooperate and execute all documents necessary to ensure such compliance, including the preparation and filing of any required FCC applications to permit the Secondary Uses of spectrum described in this Agreement.

8.2. The joint technology team will be formed within sixty (60) days of the execution of the Agreement.

8.4. The parties, through the joint technology team, will devise a methodology for identifying spectrum available for Secondary Use. The methodology may include, among other things:

     (a) dynamic detection of available spectrum;

     (b) a process whereby Customer will provide written notification to Google of availability of spectrum for Secondary Use; and/or

     (c) a reasonable period of time, to the extent feasible, within which, after Customer has either begun or stopped using certain spectrum for Primary Use in a specific area, Customer will provide notice concerning the availability of this spectrum.
