Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Amendment of Compensatory Arrangements with Outside Directors

On December 13, 2011, the Nominating and Corporate Governance Committee of the board of directors amended and restated our Compensatory Arrangements with Outside Directors, under which we pay certain equity and cash compensation to each director who constitutes an “Outside Director.”

Under the Compensatory Arrangements as previously in effect, an Outside Director was defined to mean a director who was neither (a) employed by us nor (b) affiliated with a person or entity that beneficially owns five percent or more of our common stock. Effective as of January 1, 2012, the definition of “Outside Director” was revised to mean any non-employee director. As a result of the amendment, two of our current directors, James A. Goldstein and Justin Perreault, became entitled to begin receiving director compensation as of January 1, 2012.

The other provisions of the Compensatory Arrangements, including the amount and type of compensation payable to Outside Directors, were not modified.

A copy of the Compensatory Arrangements with Outside Directors, as amended and restated as of December 13, 2011, is filed as Exhibit 10.1 to this current report on Form 8-K and is incorporated herein by reference.

Amendment of Executive Retention Agreement

On April 2, 2012, we entered into an amendment of our executive retention agreement with Mark Friedman, our chief marketing and business development officer, which originally was entered into on November 28, 2008.

Previously the executive retention agreement generally provided that, among other things, if Mr. Friedman’s employment is terminated by us for reasons other than for cause (as defined) or by Mr. Friedman for good reason (as defined), Mr. Friedman will receive a cash payment equal to the sum of (1) Mr. Friedman’s accrued compensation (including a pro rata bonus payment) through the date of his termination and (2) an amount equal to 0.5 times the sum of Mr. Friedman’s (x) highest annual base salary at any time during the twelve months prior to the termination of his employment and (y) commission, if any, for the most recently completed fiscal year prior to such termination.

Under the amendment, if Mr. Friedman’s employment is terminated other than for cause or for good reason within six months following the closing of a specified change in control, then the “multiplier” in clause (2) above will increase from 0.5 to 1.0. For these purposes, the term “change in control” means:

The other provisions of Mr. Friedman’s executive retention agreement were not modified.

The form of the above-referenced executive retention agreement, as amended, is attached as Exhibit 10.2 to this current report on Form 8-K and is incorporated herein by reference.
