1. Amendment of Section 1.6(e) of the Agreement. Section 1.6(e) of the Agreement is amended and restated in its entirety by the following:

“(e) Stock Options; Employee Stock Purchase Plan. At the Effective Time, all Assumed Options outstanding under the Option Plans shall be assumed by Parent in accordance with Section 5.9(a). At the Effective Time, each Company Option that is either (A) held by any Person other than a current employee of the Company or any of its Subsidiaries or an employee of the Company who has terminated his or her employment within 90 days prior to the Effective Time (each such Company Option, a “Non-Employee Option”) or (B) has a per share exercise price greater than $9.54, (each, an “Out-of-the-Money Option,” and together with the Non-Employee Options, the “Cashed-Out Options”), and, in each case, that is unexpired, unexercised and outstanding immediately prior to the Effective Time shall, on the terms and subject to the conditions set forth in this Agreement, terminate in its entirety at the Effective Time, and the holder of each Cashed-Out Option shall be entitled to receive therefor an amount of cash (rounded down to the nearest whole cent) equal to the product of (i) the number of shares of Company Common Stock that are subject to such Company Option and that are unexpired, unexercised and outstanding immediately prior to the Effective Time, and (ii) the excess, if any, of $9.00 over the per share exercise price of such Company Option immediately prior to the Effective Time. Each Company Option that is held by a person set forth on Exhibit A hereto, has a per share exercise price greater than $9.00 but less than or equal to $9.54 and is unexpired, unexercised and outstanding immediately prior to the Effective Time shall be a “Waived Option.” At the Effective Time, each Waived Option shall be terminated without consideration therefor. Each Company Option that is unexpired, unexercised and outstanding immediately prior to the Effective Time and is neither a Cashed-Out Option nor a Waived Option shall be an “Assumed Option.” Rights outstanding under the ESPP and any other employee stock purchase plan of the Company shall be treated as set forth in Section 5.9(c).
