The Investor Rights Agreement provides for, among other things, certain rights relating to the registration of Common Stock held by such holders. Non-Employee Director Equity Compensation The Issuer's board of directors (the "Board") adopted, and its stockholders approved, a compensation program (the "Non-Employee Director Compensation Program") for the Issuer's non-employee directors, including Mr. Encrantz. Pursuant to the Non-Employee Director Compensation Program, each non-employee director who is initially elected or appointed to the Board will receive an initial grant of restricted stock units equal to $240,000 divided by (i) the closing sales price of one share of the Issuer's Common Stock on the date of grant if the grant is made when the Issuer is in an "open window", or (ii) the closing sales price of one share of the Issuer's Common Stock on the first trading day on or following the date of approval of the award during which the Issuer is in an "open window" (the "Reference Price"). In addition, each non-employee director who (a) has been serving on the Board for at least six months as of the date of any annual meeting of stockholders after the Issuer's initial public offering and (b) will continue to serve as a non-employee director immediately following such meeting, will receive on the date of such annual meeting, a grant of restricted stock units equal to $130,000 divided by the Reference Price. The initial grant of restricted stock units vest and become exercisable in substantially equal installments on each of the first three anniversaries of the date of grant, such that the award shall be fully vested on the third anniversary of the date of grant, subject to the director's continued service as a director through each such vesting date. Each subsequent grant of restricted stock units will vest in a single installment on the earlier of the date of the next annual meeting or the first anniversary of the date of grant, subject to the director's continued service as a director through such vesting date. In addition, all unvested restricted stock units will vest in full upon the occurrence of a change in control of the Issuer. The Issuer's non-employee directors are also entitled to receive cash compensation as set forth in the Non-Employee Director Compensation Program.
