  *        *        * 
 1.
Irrevocable Exchange of Shares. 
 (a) Upon execution of this Agreement, Intel hereby irrevocably elects to exchange (the
“Share Exchange”) each share of Class B Common Stock (together with each corresponding Class B Unit) held by or on account of itself and its Affiliates (collectively, the “Intel Interests”), into the corresponding
number of shares of Class A Common Stock, in 







 
accordance with Section 7.9 of the Operating Agreement and Section 5.1 of the Charter, effective immediately prior to the Effective Time (as defined in the Merger Agreement);
provided, however, that if the Merger is not consummated for any reason at such time, the Share Exchange shall be void ab initio and Intel shall retain the Intel Interests. 

(b) Notwithstanding anything to the contrary contained in Section 7.9 of the Operating Agreement, the parties to this Agreement
agree that execution of this Agreement shall constitute timely delivery of an Exchange Notice to the Company. 
 2.
Escrow. Upon execution of this Agreement by the parties hereto, Intel covenants and agrees to deposit, within five (5) Business Days after the date hereof, all of the Intel Interests with the Company to hold such Intel Interests in
escrow (the “Escrow”) until the earlier to occur of (i) the consummation of the Share Exchange or (ii) termination of this Agreement in accordance with its terms. If this Agreement is terminated in accordance with its
terms, the Company shall promptly return to Intel all Intel Interests then being held by the Company. At any time that the Intel Shares are being held in the Escrow in accordance with this Agreement, Intel shall not Transfer the Intel Shares except

provided, however, that Intel shall have the right to terminate this Agreement by written notice to the Company and Sprint if the terms of the Merger Agreement, the Note Purchase Agreement, the Notes or the Indenture are amended, modified or waived
without the prior written consent of Intel, but only if such amendment, modification or waiver creates any additional condition to the consummation of the Merger or the transactions contemplated under the Note Purchase Agreement, the Notes and the
Indenture, reduces the amount of the Merger Consideration, changes the form of the Merger Consideration or otherwise adversely affects Intel (in its capacity as a stockholder of Clearwire or equityholder of Clearwire LLC), provided that any
amendment, waiver or modification that results in a delay in the timing of the Closing (but not beyond December 31, 2013) but does not have any other adverse effect on Intel in such capacity will not constitute grounds for termination of this
Agreement. 
 4. Entire Agreement. This Agreement constitutes the sole and entire agreement of the parties to this
Agreement with respect to the subject matter contained herein, and supersedes all prior and contemporaneous understandings and agreements, both written and oral, with respect to such subject matter. 

5. Assignment. No party may assign its rights or obligations hereunder without the prior written consent of the other parties
hereto. 
 6. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in the Company,
Clearwire Communications or Sprint any direct or indirect ownership or 







 
incidence of ownership of or with respect to the Intel Interests. All rights, ownership and economic benefits of and relating to the Intel Interests shall remain vested in and belong to Intel,
including without limitation the right to vote of any of the Intel Interests. 
 7. No Third-Party Beneficiaries. This
Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person or entity any legal or equitable right,
benefit or remedy of any nature whatsoever under or by reason of this Agreement. 
 8. Governing Law. This Agreement will

Delaware, and the parties hereto hereby irrevocably submit to the exclusive jurisdiction of such courts (and, in the case of appeals, appropriate appellate courts therefrom) in any such action or proceeding and irrevocably waive the defense of an
inconvenient forum to the maintenance of any such action or proceeding. The consents to jurisdiction set forth in this paragraph shall not constitute general consents to service of process in the State of Delaware and shall have no effect for any
purpose except as provided in this paragraph and shall not be deemed to confer rights on any Person other than the parties hereto. The parties hereto agree that a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law. 
 9. Notices.

Sprint, on the one hand, and Intel, on the other hand. 
 10. Specific Enforcement. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Court of Chancery of the State of Delaware, this being in addition to any other remedy to which such Party
