Transaction Overview Preliminary Draft - Confidential

Summary of Select Terms of the Proposed Transaction

Scope of Assignment: Evercore Group L.L.C. (“Evercore”) has been asked by the Board of Directors of Clearwire Corporation (“Clearwire”, “CLWR” or the “Company”) whether, in Evercore’s opinion as of the date hereof, the consideration of $3.40 to be received by Clearwire Class A shareholders from Sprint Nextel Corporation (“Sprint”) is fair, from a financial point of view, to all non-Sprint/SoftBank shareholders of the Clearwire Class A common stock (the “Transaction”)

Valuation: Purchase Price per share: $3.40

Consideration: Consideration: 100% cash

Each Class A Common Share / Each Class B Share and Unit, together: Same consideration

– 100% of non-Sprint/SoftBank shares, including public shareholders (34.5% of fully-diluted shares) and Equityholders (Comcast/ Bright House/ Intel, owners of 11.5% of fully-diluted shares), which represents 46.0% of total fully-diluted ownership (1)

Transaction Structure: Reverse subsidiary merger, whereby Sprint acquisition subsidiary is to merge into Clearwire Corporation

Clearwire will be the surviving entity

Conditions Precedent to Close: Approval by a required vote of Clearwire shareholders

Closing of Sprint and SoftBank transaction

Required legal and regulatory approvals

No Material Adverse Effect at Clearwire

Shareholder Vote: May 21st Clearwire shareholder meeting adjourned until May 31st

Transaction Overview Preliminary Draft - Confidential

Summary of Select Terms of the Proposed Transaction (Cont’d)

Interim Financing: Sprint has provided $240mm of financing pursuant to a Note Purchase Agreement, dated as of December 17, 2012 as amended on January 31, 2013 and February 26, 2013, since the transaction was announced

– Instrument is 1% unsecured Exchangeable Notes, with conversion price of $1.50 and maturing in June 2018 (5 years)

– Monthly installments of $80mm

– Shareholder vote is required when Nasdaq 20% limit is reached or Clearwire runs out of authorized shares

If Clearwire shareholders approve the Transaction, Clearwire will be entitled to 5 additional monthly draws; if the Transaction fails, no further draws will be available

If Deal Terminates: Due to failure of Clearwire shareholder vote:

– Exchangeable Notes conversion price of $1.50/share; conversion at option of Sprint.

Merger Agreement is terminated due to failure of Sprint/SoftBank merger:

– Sprint will forgive $120mm of Exchangeable Notes and the balance may be converted at Clearwire’s option within 15 business days of termination into common shares at $1.50/share;

– Sprint will pay Clearwire an additional $100mm prepayment for future LTE services on 1/15/14 if Clearwire has met its build-out requirement of 5,000 sites by 1/15/14

Due to termination for any reason, Sprint has the option to convert at any time after termination of agreement, subject to Clearwire’s option to convert notes if Merger Agreement is terminated due to failure of Sprint/SoftBank merger

Due to Sprint breaches of the Merger Agreement or failure of Sprint/SoftBank merger, Sprint’s obligation to purchase notes will continue until the earlier of (i) Clearwire exchanging outstanding notes for equity or (ii) July 2, 2013 (after the 7th draw), however clause (ii) will not apply if the accelerated build-out agreement has been executed, is in full force and effect and has not been breached by Clearwire.
