3. Repurchase Rights.

3.1 If the Stockholder’s position as director with the Company is terminated by the Company or by the Stockholder voluntarily for any reason, or no reason, the Company (or, at the Company’s election, any parent or subsidiary of the Company) shall have the right to purchase (“Repurchase Right”), and the Stockholder shall, at the election of the Company, be obligated to sell all or any part of the Unvested Shares (as such term is defined below) owned by him at the time of termination at the purchase price and on the terms provided in Section 3.2.

3.2 The Company may exercise its Repurchase Right by giving written notice to the Stockholder (or his legal representatives) at any time within 60 days following the termination of his directorship with the Company, specifying the number Unvested Shares it wishes to purchase. The purchase price per Unvested Share shall be its Original Purchase Price (subject to equitable adjustment upon the occurrence of any Recapitalization Event).

3.3 Within thirty (30) days after receipt of the notice of the exercise of any Repurchase Right described in this Agreement, the Stockholder (or his legal representatives) shall deliver to the Company the certificate(s), together with duly executed stock powers, representing the Unvested Shares being repurchased by the Company, against payment to the Stockholder (or his legal representatives), in the manner provided in Section 5, for the aggregate purchase price for such Unvested Shares. Upon the date of such notice from the Company to the Stockholder (or his legal representatives), the interest of the Stockholder (and of his legal representatives) in the Unvested Shares specified in such notice shall automatically terminate, except for the right to receive payment from the Company for such Unvested Shares.

4 Vesting and Release of Shares from Repurchase Rights.

For purposes of this Agreement, a “Change in Control shall be defined as:

From and following the date that any Share becomes a Vested Share, the Stockholder may, at his option or election, deliver to the Escrow Agent and the Company a direction to release any such Vested Share(s) from the escrow arrangement of Section 7 hereof and remove the Restricted Stock Legend from the certificate or certificates evidencing such Vested Share(s). Promptly thereafter, the Escrow Agent and Company shall undertake such actions as are necessary to deliver to the Stockholder a certificate or certificates, with the Restricted Stock Legend removed, representing such Vested Shares, including such actions as delivering appropriate replacement certificates registered in the Stockholder’s name (a) to the Stockholder directly in the case of Vested Shares, with the Restricted Stock Legend removed and (b) to the Escrow Agent in the case of any remaining Unvested Shares, with the Restricted Stock Legend in place.
