Dear Fellow Clearwire Stockholders,

Crest Financial Ltd (“Crest”) writes one final time with respect to Clearwire Corporation (“Clearwire”) and its proposed merger transaction with Sprint Nextel Corporation (“Sprint”). As you know, recently Sprint raised the price it will pay in the merger to $5 per share. As we are now satisfied with these terms, which represents a 68% increase to the initial merger consideration of $2.97, we have agreed with Sprint and Clearwire to cease opposition to the transaction and to vote in favor of the merger.

We are proud of our campaign and stand by our analysis. At the same time, with this favorable resolution, we withdraw any statements made in the heat of battle that may be construed as disparaging to Clearwire, Sprint, their directors and officers, or any other participants in this hard fought contest.

Thank you to all who took the time to meet with us by phone or in person and listened to our views on the proposed transaction. Congratulations to all Clearwire stockholders.

Sincerely yours,

/s/ David K. Schumacher
