(d) On March 21, 2012, the board of directors (the “Board”) of Ubiquiti Networks, Inc. (the “Company”) appointed Bill Gurley as a Class I director to serve for the remainder of the Class I director term or until his successor is duly elected and qualified. Mr. Gurley will also serve as a member of the audit committee of our Board (the “Audit Committee”). The Board has affirmatively determined that Mr. Gurley meets the independence criteria for board and audit committee members and that he qualifies as an “audit committee financial expert” under federal securities laws and the listing standards of The NASDAQ Stock Market.

In connection with the appointment of Mr. Gurley to the Board and Audit Committee, the Board has accepted the resignation of John L. Ocampo from the Audit Committee, such that the Audit Committee is now composed of Robert M. Van Buskirk (chair), Charles J. Fitzgerald and Mr. Gurley. The Company and Mr. Gurley intend to enter into the Company’s standard form of indemnification agreement, a copy of which is filed as Exhibit 10.1 to the Company’s Registration Statement on Form S-1 (Registration No. 333-174974) as declared effective by the Securities and Exchange Commission on October 13, 2011.

There are no understandings or arrangements between Mr. Gurley or any other person and the Company or any of its subsidiaries pursuant to which Mr. Gurley was elected to serve as a director. There are no family relationships between Mr. Gurley and any director, executive officer or person nominated by the Company to become a director or executive officer, and there are no transactions between Mr. Gurley or any of his immediate family members and the Company or any of its subsidiaries that would be required to be reported under Item 404(a) of Regulation S-K.

Mr. Gurley is a general partner of Benchmark Capital, a venture capital firm, which he joined in March 1999. Prior to joining Benchmark Capital, Mr. Gurley was a partner with Hummer Winblad Venture Partners, a venture capital firm, and a research analyst for Credit Suisse First Boston, an investment bank. Mr. Gurley holds a Master of Business Administration degree from the University of Texas and a Bachelor of Science degree in Computer Science from the University of Florida.

On March 22, 2012, we issued a press release announcing Mr. Gurley’s appointment to our board of directors. A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated by reference herein.
