   31, 2011, Sprint, through Sprint HoldCo LLC, a wholly-owned subsidiary, owned the largest interest
   in Clearwire with an effective voting and economic interest in Clearwire of approximately 54% and
   Intel Corporation, Google Inc., Comcast, Time Warner Cable Inc., Bright House Networks, LLC and
   Eagle River Holdings LLC collectively owned a 32% interest in Clearwire.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Sprint Wholesale Relationship&lt;/i&gt; &lt;/b&gt;&amp;#8212; As noted above, Sprint owned the largest interest in Clearwire as of March&amp;#160;31, 2011.
   We have a number of material arrangements with Sprint including a non-exclusive 4G MVNO agreement
   whereby we sell 4G wireless broadband services to Sprint and other parties for the purposes of
   marketing and reselling our 4G wireless broadband services to their respective end user subscribers
   and a non-exclusive 3G MVNO agreement whereby Sprint sells to us its code division multiple access
   and mobile voice and data communications services, which we refer to collectively as 3G wireless
   services, for purposes of resale to our retail customers. For the three months ended March&amp;#160;31, 2011
   and 2010, we received $33.0&amp;#160;million and $1.6&amp;#160;million, respectively from Sprint for 4G broadband
   wireless services we provide to Sprint and other parties. For the three months ended March&amp;#160;31, 2011
   and 2010 we paid $8.7&amp;#160;million and $0, respectively to Sprint for 3G wireless services provided by
   Sprint to us. Sprint is a significant wholesale customer of our 4G wireless broadband services. During the three months ended March 31, 2011,
   wholesale revenue recorded attributable to Sprint comprised approximately 25% of total revenues. See Note 17, Subsequent Event for a description of the recent resolution of the
   ongoing disputes between the Sprint and Clearwire relating to wholesale pricing terms under
   existing commercial agreements.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Sprint Master Site Agreement &amp;#8212; &lt;/i&gt;&lt;/b&gt;We entered into a master site agreement with Sprint, which we refer
   to as the Master Site Agreement, pursuant to which Sprint and we established the contractual
   framework and procedures for the leasing of tower and antenna collocation sites to each other.
   Leases for specific sites will be negotiated by Sprint and us on request by the lessee. The leased
   premises may be used by the lessee for any activity in connection with the provision of wireless
   communications services, including attachment of antennas to the towers at the sites. The term of
   the Master Site Agreement is ten years from the Closing. The term of each lease for each specific
   site will be five years, but the lessee has the right to extend the term for up to an additional 20
   years. The monthly fee will increase 3% per year. The lessee is also responsible for the utility
   costs and for certain additional fees. During the three months ended March&amp;#160;31, 2011 and 2010, we
   recorded rent expense of $14.3&amp;#160;million and $9.3&amp;#160;million, respectively.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Davis Wright Tremaine LLP &lt;/i&gt;&lt;/b&gt;&amp;#8212; The law firm of Davis Wright Tremaine LLP serves as our primary
   outside counsel, and handles a variety of corporate, transactional, tax and litigation matters. Mr.
   Wolff, who currently sits on our board of directors and is our former Chief Executive Officer, is
   married to a partner at Davis Wright Tremaine LLP. However, Mr.&amp;#160;Wolff&amp;#8217;s spouse has not received any
   compensation directly from us. For the three months ended March&amp;#160;31, 2011 and 2010, we paid $596,000
   and $1.0&amp;#160;million to Davis Wright Tremaine LLP for legal services, respectively. This does not
   include fees paid by Old Clearwire.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Ericsson, Inc &lt;/i&gt;&lt;/b&gt;&amp;#8212; Ericsson, Inc., which we refer to as Ericsson, provides network deployment
   services to us, including site acquisition and construction management services. Dr.&amp;#160;Hossein
   Eslambolchi, who currently sits on our board of directors, had a consulting agreement with
   Ericsson. As part of his consulting agreement, Dr.&amp;#160;Eslambolchi received payments for his services
   from Ericsson. He has not received any compensation directly from us related to his relationship
   with Ericsson. For the three months ended March&amp;#160;31, 2011, we capitalized $8.8&amp;#160;million in costs paid
   to Ericsson to Network and Base Station Equipment, of which $7.1&amp;#160;million was included in Accounts
   payable and other current liabilities.
