YOUR VOTE IS IMPORTANT

PLEASE SUBMIT YOUR PROXY TODAY

July 19, 2010

Dear Fellow Stockholder:

We have previously mailed to you proxy materials in connection with the Special Meeting of Stockholders of EF Johnson Technologies, Inc., (“EFJI”) to be held on August 11, 2010.  Your vote is important and your participation is requested at this important meeting.

As you may know, the board of directors of EF Johnson Technologies, Inc. has unanimously approved a merger agreement providing for the acquisition of EF Johnson Technologies, Inc. by FP-EF Holding Corporation, an affiliate of Francisco Partners II, L.P. If the merger agreement is completed, you will be entitled to receive $1.50 in cash, without interest and less any applicable withholding tax, for each share of EF Johnson Technologies, Inc. common stock owned by you immediately prior to completion of the merger (unless you have properly and validly perfected your statutory rights of appraisal with respect to the merger).

The Board considered the relationship of the merger consideration to the current and historical market prices of the Company’s Common Stock and the fact that the merger consideration was to be paid in cash, which would provide stockholders with the opportunity for liquidity and to receive a premium over the current and recent prices of the Common Stock. The Board reviewed historical market prices, volatility and trading information with respect to the Common Stock, including the fact that the merger consideration represented a premium of 48.2% over the average closing price per share of Common Stock on the NASDAQ Global Market over the 30 trading days prior to June 18, 2010, 48.0% over the average closing price per share of Common Stock over the 90 trading days prior to June 18, 2010, 46.7% over the average closing price per share of Common Stock over the 180 trading days prior to June 18, 2010 and 45.8% over the average closing price per share of Common Stock for the one year prior to June 18, 2010.

The Board of Directors unanimously recommends that our stockholders vote “FOR” the proposal to adopt the Merger Agreement and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies .

Completion of the Merger requires the adoption of the Merger Agreement by the affirmative vote of the holders of a majority of shares of Common Stock issued and outstanding. Failure to vote your shares of Common Stock by proxy or in person or an abstention will have the same effect as voting against adoption of the Merger Agreement. Approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of a majority of the votes cast by the holders of all Common Stock present in person or represented by proxy at the special meeting and entitled to vote on the matter. Failure to vote your shares of Common Stock or an abstention will have no effect on the approval of the proposal to adjourn the special meeting.

Even if you plan to attend the special meeting in person, we request that you mark, sign, date and return the enclosed proxy or submit your proxy by telephone or the Internet prior to the special meeting to ensure that your shares will be represented at the special meeting if you are unable to attend. If you have previously returned your proxy, please accept our thanks and disregard this request.

Thank you for your cooperation, continued support and prompt response.
