The increase in the size of the board of directors and the election of Mr. Singh to fill the newly created vacancy on the Board was based upon the recommendations of the Nominating and Corporate Governance Committee of the Board.

Mr. Singh has served the Chief Executive Officer of Concur Technologies, Inc., a provider of integrated travel and expense management solutions, since 1996 and as a director of Concur since 1993, including service as Chairman of the Board of Directors since September 1999.

Mr. Singh currently serves as Chairman of the GBTA Foundation Board and serves on the boards of directors of ClearTrip Inc., AdReady, and Washington Roundtable. The Company believes that Mr. Singh possesses specific attributes that qualify him to serve as a member of the Board, including his experience leading and managing technology companies and his service as a director of other technology companies.

There are no arrangements or understandings between Mr. Singh, on the one hand, and the Company or any other persons, on the other, pursuant to which Mr. Singh was selected as a director. There are no related party transactions between the Company and Mr. Singh (or any immediate family member thereof) requiring disclosure under Item 404(a) of Regulation S-K.

As a non-employee director, Mr. Singh will be entitled to receive an annual retainer of $35,000 in connection with his appointment to the Board. As a member of the Nominating and Corporate Governance Committee of the Board, Mr. Singh will also be entitled to receive an additional annual retainer of $2,500.

In connection with his appointment to the Board, Mr. Singh will be granted an initial stock option award to purchase shares of the Company’s common stock with a target value of $350,000 using Black-Scholes methodology. The exercise price of each such option will be equal to the fair market value of the Company’s common stock on the date of grant. Such initial stock option award will vest as to 1/3 of the shares subject to the option on the first anniversary of the date that Mr. Singh joined the board, and the remaining shares will vest monthly in equal increments over the following two years. In addition, on the date of each of the Company’s annual stockholder meetings, Mr. Singh will be eligible to receive an annual stock option award to purchase shares of the Company’s common stock with a target value of $175,000 using Black-Scholes methodology. The exercise price of each such option will be equal to the fair market value of our common stock on the date of grant. Each annual stock option award will vest on the first anniversary of the date of grant.

Mr. Singh will execute the Company’s standard form of indemnification agreement, a copy of which has been filed as Exhibit 10.1 to the Amendment No. 3 to the Company’s Registration Statement on Form S-1 (File No. 333-169621) filed with the Securities and Exchange Commission on December 17, 2010.
