W I T N E S S E T H :

WHEREAS, Parent, Acquisition Sub and the Company desire to amend the Merger Agreement, in accordance with Section 8.4 thereof, as set forth below.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the parties agree as follows:

1. Amendment to Section 3.1(b) of the Merger Agreement.  Section 3.1(b) of the Merger Agreement is hereby amended and restated in its entirety to read as follows:

(b) Conversion of Company Securities. Except as otherwise provided in this Agreement, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (after giving effect to the Recapitalization, including the Total Option Cash Payment, and other than shares canceled pursuant to Section 3.1(a) and Dissenting Shares) shall be converted into the right to receive $7.64 in cash, without interest (the “Merger Consideration”).  Each share of Company Common Stock to be converted into the right to receive the Merger Consideration as provided in this Section 3.1(b) shall be automatically canceled and shall cease to exist, and the holders of certificates (the “Certificates”) or book-entry shares (“Book-Entry Shares”) which immediately prior to the Effective Time represented such Company Common Stock shall cease to have any rights with respect to such Company Common Stock other than the right to receive, upon surrender of such Certificates or Book-Entry Shares in accordance with Section 3.2, the Merger Consideration, without interest thereon.

2. Amendment to Section 4.3(a) of the Merger Agreement.  Section 4.3(a) of the Merger Agreement is hereby amended and restated in its entirety to read as follows:

(a) The authorized capital stock of the Company consists of 250,000,000 shares of Company Common Stock and 50,000,000 shares of the Company’s preferred stock, par value $0.001 per share (the “Preferred Stock”). As of November 30, 2012, (i)  54,203,288 shares of Company Common Stock were issued and outstanding, (ii) no shares of Preferred Stock were issued and outstanding, (iii) 190,199 shares of Company Common Stock were held in treasury and (iv) no shares were held by a wholly owned subsidiary of the Company.  As of November 30, 2012 there were (i) 1,477,900 shares of Company Common Stock reserved for issuance pursuant to the Company ESPP; (ii) 11,168,569 shares of Company Common Stock reserved for issuance under the 1998 Plan, with Company Options to purchase 5,248,915 shares of Company Common Stock outstanding; (iii) 22,055 shares reserved for issuance under the Supplemental Purchase Plan; (iv) 180,000 shares of Company Common Stock reserved for issuance under the Directors’ Stock Option Plan, with Company Options to purchase 180,000 shares of Company Common Stock outstanding; (v) 194,100 shares reserved for issuance pursuant to the 2002 Plan, with Company Options to purchase 194,100 shares of Company Common Stock outstanding; and (vi) unvested and outstanding Company Restricted Stock Units with respect to 1,389,505 shares of Company Common Stock.  Except as set forth above, as of November 30, 2012, no shares of capital stock of, or other equity or voting interests in, the Company, or options, warrants or other rights to acquire any such stock or securities were issued, reserved for issuance or outstanding.  All outstanding shares of capital stock of the Company are, and all shares that may be issued pursuant to the Company ESPP and the Company Plans will be, when issued in accordance with the terms thereof, duly authorized, validly issued, fully paid and non-assessable and not subject to preemptive rights.

3. Amendment to Section 6.14 of the Merger Agreement.  Section 6.14 of the Merger Agreement is hereby amended and restated in its entirety to read as follows:

6.14 Recapitalization and Holdback; Tax Characterization.  Following the closing of the Patent Sale Transaction but prior to the Closing, the Company shall, subject to obtaining the Requisite Stockholder Approval, effect the Recapitalization by filing a certificate of amendment to the Amended and Restated Certificate of Incorporation of the Company in substantially the form attached hereto as Exhibit A (the “Recapitalization Certificate”); provided however, that the Company shall take all actions

necessary or appropriate such that the aggregate Recapitalization amount shall be reduced to the extent necessary to cause the Company to have available cash, following the Recapitalization, in an amount equal to at least Ninety-Nine Million Seven Hundred Thousand Dollars ($99,700,000), as may be adjusted in the event of an Alternative Patent Sale Agreement (the “Holdback Amount”).  Parent, Acquisition Sub and the Company acknowledge and agree that (x) each share of Company Common Stock issued and outstanding immediately prior to the Recapitalization shall, as a result of the Recapitalization, be converted into the right to receive an amount in cash equal to (i) (a) the amount of cash held by the Company following the closing of the Patent Sale Transaction less (b) the Holdback Amount, less (c) the Total Option Cash Payments divided by (ii) (a) the outstanding shares of Company Common Stock plus (b) the outstanding Company Restricted Stock Units, to be calculated one Business Day prior to the Recapitalization in accordance with Schedule 6.14 of the Company Disclosure Schedule  (the “Recapitalization Cash Portion”, and the sum of all such payments, the “Total Recapitalization Cash Portion”) and 0.1887 shares of Company Common Stock, and (y) the Recapitalization of Company Common Stock is both a condition to, and part of a plan that includes, the consummation of the Merger.  Accordingly, Parent, Acquisition Sub and the Company shall treat, and shall cause their affiliates to treat, such Recapitalization and the conversion of Company Common Stock described in Section 3.1(b) as a single integrated transaction for U.S. federal income Tax purposes governed by Xxxx x. Xxxxxxxxx, 213 F.2d 914 (6th Cir. 1954) and Revenue Ruling 54-458, 1954-2 C.B. 167, and shall file all Tax Returns and reports consistent with such treatment, shall not treat any portion of the Recapitalization as a dividend for U.S. federal income Tax purposes, and shall take no position inconsistent therewith in any such Tax Return or report or in any proceeding in respect of Taxes.

4. Amendments to Section 7.1 of the Merger Agreement.

(a) Section 7.1(c) of the Merger Agreement is hereby amended and restated in its entirety to read as follows:

9. Miscellaneous.

(a) From and after the date hereof, all references in the Merger Agreement to “this Agreement” shall be deemed to mean the Merger Agreement as amended by this Amendment, but references to “the date of this Agreement,” or “the date hereof” in the Merger Agreement, as amended by this Amendment, shall be deemed to be November 5, 2012.

(b) Except as expressly amended hereby, the Agreement shall remain in full force and effect.

(c) Each party to this Amendment hereby represents that it has all requisite corporate power and authority to enter into and deliver this Amendment, to perform its obligations under the Amendment, and to consummate the transactions contemplated by this Amendment; that the execution and delivery of this Amendment and the consummation of the transactions contemplated by this
