Appointment of Mr. Hajjar to the Board

On February 9, 2010, the Board of Directors of the Company (the “Board”) appointed W. Douglas Hajjar to the Board. In connection with Mr. Hajjar’s appointment to the Board, the Board adopted an amendment to the Company’s bylaws and a resolution to increase the size of the Board to eight (8) directors. The initial term of Mr. Hajjar will run up to the 2010 annual meeting of stockholders. In connection with his service to the Company as a director, Mr. Hajjar will be entitled to receive an annual cash retainer and meeting fees in accordance with the Company’s director compensation policy, as well as an initial restricted stock grant of 20,000 shares of the Company’s Common Stock under the Company’s 2007 Stock Plan. The Board also appointed Mr. Hajjar to its audit committee.

Since the beginning of the Company’s last fiscal year, there was no transaction or series of similar transactions, nor is there any currently proposed transaction or series of similar transactions, to which the Company or any of its subsidiaries was or is to be a party, in which the amount involved exceeds $120,000 and in which Mr. Hajjar, or members of their respective immediate families, had or will have a direct or indirect material interest, other than his director compensation arrangements described above.

Hajjar currently serves as Chairman of Blue Wave Wireless, a telecommunications infrastructure company. From 1997 to 2007, he served as Chairman of Wherify Wireless Inc., a leading developer of wireless location products and services, which he co-founded in 1997. From 2000 to 2007, he was Chairman of Maui Innovative Technologies, a company he co-founded to develop Top Secret weapon systems for the military. From 1991 to 1997, Hajjar was Chairman of Control Data Systems Inc. Previously, he served as vice-chairman of Cadence Design Systems Inc., and was chairman and chief executive officer of Valid Logic at the time of its acquisition by Cadence. He also held executive positions in operations and finance at Genrad and M/ACom. Hajjar earned his BSBA in accounting at Boston College and served as an Army Intelligence Officer in Vietnam.

Attached to this Current Report as Exhibit 99.1 is a copy of the news release, dated February 11, 2010, announcing the appointment of Mr. Hajjar to the Board.

On February 9, 2010, the Board approved an amendment to the Company’s Amended and Restated Bylaws (the “Bylaws”). The amendment revises Article III, Section 2 of the Bylaws to remove the range requirements for the size of the Board, allowing the Board to fix the exact number of directors from time to time by resolution of affirmative vote of a majority of the entire Board. In connection with this amendment, the Board resolved to increase the number of authorized directors on the Board from seven (7) to a total of eight (8).

The foregoing description of the amendment to the Bylaws does not purport to be complete and is qualified in its entirety by reference to such amendment, which is included as Exhibit 3.1 to this Current Report on Form 8-K and incorporated herein by reference.
