Item 1.01 Entry into a Material Definitive Agreement.

On February 26, 2013, Clearwire Corporation (the “Company”) entered into an amendment (the “Second Note Purchase Agreement Amendment”) to the Note Purchase Agreement, dated December 17, 2012 (the “Note Purchase Agreement”), as amended by the First Amendment to the Note Purchase Agreement, dated January 31, 2013 (together with the Note Purchase Agreement, the “Amended Note Purchase Agreement”) by and among the Company, Clearwire Communications LLC, Clearwire Finance Inc. (together with Clearwire Communications LLC, the “Issuers”) and Sprint Nextel Corporation (“Sprint”).

Pursuant to the terms of the Amended Note Purchase Agreement, if the Company could not execute a build-out agreement with Sprint by February 28, 2013 (or, if a build-out agreement with Sprint was executed by February 28, 2013, if such agreement was not in full force and effect or the Company was in breach of any obligations under such agreement) (collectively, the “Draw Conditions”), then the Issuers would not be able to request financing from Sprint under the Amended Note Purchase Agreement on the last three draw dates (in August, September and October 2013). The Second Note Purchase Agreement Amendment amended the Amended Note Purchase Agreement to delete the Draw Conditions and to permit the Issuers to request financing from Sprint on the last three draw dates without any such condition being met.

The foregoing description of the Second Note Purchase Agreement Amendment is not complete and is qualified in its entirety by reference to the Second Note Purchase Agreement Amendment, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

Item 8.01 Other Events.

The Company hereby furnishes the information in Exhibit 99.1 hereto, a press release dated February 27, 2013, and in Exhibit 99.2 hereto, an email communication to Clearwire employees by Erik Prusch, President and CEO, on February 27, 2013.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the securities laws. The words “may,” “could,” “should,” “estimate,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “target,” “plan,” “providing guidance” and similar expressions are intended to identify information that is not historical in nature.

This Current Report on Form 8-K contains forward-looking statements relating to the proposed merger and related transactions (the “transaction”) between Sprint and Clearwire. All statements, other than historical facts, including statements regarding the expected timing of the closing of the transaction; the ability of the parties to complete the transaction considering the various closing conditions; the expected benefits and efficiencies of the transaction; the competitive ability and position of Sprint and Clearwire; and any assumptions underlying any of the foregoing, are forward- looking statements. Such statements are based upon current plans, estimates and expectations that are subject to risks, uncertainties and assumptions. The inclusion of such statements should not be regarded as a representation that such plans, estimates or expectations will be achieved. You should not place undue reliance on such statements. Important factors that could cause actual results to differ

materially from such plans, estimates or expectations include, among others, any conditions imposed in connection with the transaction, approval of the transaction by Clearwire stockholders, the satisfaction of various other conditions to the closing of the transaction contemplated by the merger agreement, and other factors discussed in Clearwire's and Sprint's Annual Reports on Form 10- K for their respective fiscal years ended December 31, 2012 and December 31, 2011, respectively, their other respective filings with the U.S. Securities and Exchange Commission (the “SEC”) and the proxy statement and other materials that will be filed with the SEC by Clearwire in connection with the transaction. There can be no assurance that the transaction will be completed, or if it is completed, that it will close within the anticipated time period or that the expected benefits of the transaction will be realized.

Clearwire does not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. Readers are cautioned not to place undue reliance on any of these forward-looking statements.
