   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;17. Subsequent Event&lt;/b&gt;
   &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;On April&amp;#160;18, 2011, we entered into the Sprint Wholesale Amendments pertaining to new wholesale
   pricing terms for the 4G wireless broadband services we provide to Sprint and the 3G wireless
   services provided by Sprint to us. Those agreements are as follows: (1)&amp;#160;April&amp;#160;2011 Clearwire /
   Sprint Amendment to the 4G MVNO Agreement, which we refer to as the 4G Amendment; (2)&amp;#160;First
   Amendment to the December&amp;#160;23, 2009 Dual Mode Settlement Letter Agreement, which we refer to as the
   Dual Mode
   Amendment; (3)&amp;#160;Settlement and Release Agreement, which we refer to as the Settlement
   Agreement; (4)&amp;#160;Sprint / Clearwire First Amendment to the MVNO Support Agreement (3G), which we
   refer to as the 3G Amendment; and (5)&amp;#160;Amended and Restated Enhanced In-Building Coverage Deployment
   Agreement, which we refer to as the CNS Agreement.
   &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;The 4G Amendment amends the terms upon which Clearwire sells 4G wireless broadband services to
   Sprint and its subsidiaries and affiliates under the 4G MVNO Support Agreement dated November&amp;#160;28,
   2008, which we refer to as the 4G Agreement. The initial term period of the 4G Agreement remains
   unchanged, with a termination date of November&amp;#160;28, 2013, and automatic five year renewal periods.
   The 4G Amendment includes, among other things, the following material terms:
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;A take-or-pay commitment from Sprint to Clearwire in the amount of $300.0&amp;#160;million for
   2011 and $550.0&amp;#160;million for 2012, which is subject to certain exceptions and payable in
   quarterly increments;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;A $175.0&amp;#160;million pre-payment from Sprint, payable in quarterly increments in 2011 and
   2012, for 4G wireless broadband services purchased from Clearwire during the remainder of
   the term of the 4G Agreement. For 2011 and 2012, the pre-payment will be applied to
   invoices for services that are not eligible for the take-or-pay commitments and after
   exhaustion of the applicable take-or-pay commitment, and for 2013 and beyond, the
   pre-payment will be applied to invoices until exhausted;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;A usage-based pricing structure for most 4G wireless broadband services provided to
   Sprint. Under this structure, the amount paid by Sprint for 4G wireless broadband
   services will be determined on a per-gigabyte, which we refer to as GB, basis for the
   aggregate volume of data usage by Sprint&amp;#8217;s customers on Clearwire&amp;#8217;s network for a
   particular month. The 4G Amendment includes multiple volume pricing tiers that are used
   in determining the per-GB price, with the price decreasing for usage that exceeds certain
   aggregate monthly volume thresholds. The 4G Amendment includes a market rate adjustment
   mechanism that may adjust the per-GB pricing beyond 2012 if there are changes in certain
   agreed-upon indexes;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;For Sprint&amp;#8217;s customers with low or no usage on Clearwire&amp;#8217;s 4G mobile broadband network,
   including those residing outside of Clearwire&amp;#8217;s launched markets, there is a nominal
   minimum fee payable per device, subject to exceptions;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;Certain other pricing plans are also available to Sprint for specific and unique services;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;Subject to certain restrictions under the 4G Amendment, Sprint is permitted to resell the
   4G wireless broadband service on a wholesale basis to other companies, and those
   companies, in turn, may resell the 4G wireless broadband service on a wholesale basis.
   For 4G wireless broadband services resold on a wholesale basis by Sprint, the prices paid
   to Clearwire by Sprint are generally determined under the same pricing structure as for
   Sprint retail customers, with Sprint being required to also pay Clearwire a small
   premium;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;A most favored reseller provision that generally grants Sprint the right to receive the
   lowest prices Clearwire charges resellers for 4G wireless broadband services, subject to
   certain limitations; and&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr valign="top" style="font-size: 10pt; color: #000000; background: transparent"&gt;
       &lt;td width="4%" style="background: transparent"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&lt;b&gt;&amp;#8226;&lt;/b&gt;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;An additional pricing discount for Sprint relative to the prices paid by other resellers
   for the 4G wireless broadband services. Under the 4G Amendment, Sprint has agreed to
   waive this discount if certain other triggering events occur.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &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;The Dual Mode Amendment resolves a pending dispute concerning how Clearwire and Sprint will
   allocate future revenue from 4G wireless broadband service usage by other parties to the 4G
   Agreement over dual mode devices that utilize both Sprint&amp;#8217;s 3G and Clearwire&amp;#8217;s 4G networks. The
   Settlement Agreement resolves disputes between Clearwire and Sprint over amounts due and owing for
   (a)&amp;#160;prior usage by Sprint&amp;#8217;s end users of Clearwire&amp;#8217;s 4G wireless broadband service, (b)&amp;#160;prior usage
   by Clearwire&amp;#8217;s end users of Sprint&amp;#8217;s 3G wireless service, and (c)&amp;#160;other disputes between Clearwire
   and Sprint over the allocation of revenue from 4G wireless broadband services usage over dual mode
   devices. In settlement of those disputes and in consideration for other transactions entered into
   by the parties, Sprint will pay Clearwire a net $28.2&amp;#160;million. Under the Settlement Agreement, the
   parties also agreed to withdraw from the pending arbitration proceeding.
   &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;The 3G Amendment amends the 3G MVNO Support Agreement dated November&amp;#160;28, 2008, which we refer
   to as the 3G Agreement, under which Sprint sells 3G wireless service to Clearwire and certain other
   parties. The 3G Amendment replaces Schedule&amp;#160;1.0 of the 3G Agreement with a new Schedule&amp;#160;1.0 setting
   forth the prices to be paid by Clearwire for the 3G wireless service and the terms under which
   Clearwire can resell 3G services on a retail and wholesale basis.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Under the CNS Agreement, Sprint will be entitled to deploy at its cost and expense an
   unlimited number of custom network solutions, which we refer to as CNS, designed to enhance
   in-building 4G network coverage for Sprint&amp;#8217;s customers. The CNS deployments must be compatible with
   Clearwire&amp;#8217;s 4G network and generally are extensions of Clearwire&amp;#8217;s 4G network. However, Sprint is
   entitled to deploy up to 1,000 wireless local area networks, which we refer to as WLANs, that are
   not an extension of the 4G network, but which transmit on a portion of Clearwire&amp;#8217;s spectrum. In
   each case, any such deployment remains subject to design approval and certain other approvals by
   Clearwire. The CNS Agreement requires Sprint to pre-pay Clearwire in advance for certain design
   review and engineering services. In addition, Sprint is required to pay Clearwire monthly recurring
   charges that vary based upon the type and size of the CNS deployment in lieu of usage based
   charges. The CNS Agreement allows Clearwire end users to roam on Sprint&amp;#8217;s CNS deployments at no
   charge to Clearwire. Under the CNS Agreement, Clearwire may, in its discretion, elect to purchase
   the CNS equipment installed by Sprint at an agreed price, provided that Clearwire continues to
   support Sprint&amp;#8217;s CNS customers for a specified period of time after consummation of such purchase.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;Pro forma effect of Sprint Wholesale Amendments on First Quarter Results
   &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;The pricing provisions agreed to in the 4G Amendment are applicable from and after January&amp;#160;1,
   2011. However, in accordance with U.S. GAAP applicable to revenue recognition, our first quarter
   results do not reflect the additional revenues due to us as a result of the April&amp;#160;18, 2011
   amendments noted. During our second quarter of fiscal 2011, we will recognize revenue of
   approximately $16.1&amp;#160;million attributable to services provided in the first quarter. Had the 4G
   Amendment been in effect as of March&amp;#160;31, 2011, our pro forma revenues for the first quarter of 2011
   would have increased by $16.1&amp;#160;million, and the pro forma Net loss attributable to Clearwire
   Corporation would have decreased by $4.0&amp;#160;million ($0.02 per share).
   &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;On April&amp;#160;27, 2011 we received a cash payment of $181.5&amp;#160;million comprised of the initial
   installments of the take-or-pay commitment for 2011 and the pre-payment and the $28.2&amp;#160;million
   settlement amount in accordance with the Settlement Agreement. In the second quarter of 2011, in
   addition to revenues earned during the second quarter, we expect to record the $16.1&amp;#160;million of
   revenue attributable to services provided in the first quarter, and the portion of the $28.2
   million of cash received related to services provided in periods prior to December&amp;#160;31, 2010.
