Section 1.2             Closing.  The closing of the Merger (the “Closing”) shall take place at 9:00 a.m., Eastern time, on the second Business Day following the satisfaction or, to the extent permitted by applicable Law, waiver of the conditions set forth in Article VI (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permitted by applicable Law, waiver of those conditions), at the offices of Gibson, Dunn & Crutcher LLP, 1881 Page Mill Road, Palo Alto, California 94304, unless another date, time or place is agreed to in writing by Parent and the Company; provided, however, that if the Closing would otherwise occur pursuant to this Section 1.2 on a date falling on or after June 15, 2011 and on or prior to June 30, 2011, then the Closing shall instead occur at 9:00 a.m., Eastern time, on July 1, 2011, unless another date, time or place is agreed to in writing by Parent and the Company.  The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

EFFECT ON THE CAPITAL STOCK OF THE

Section 2.1             Conversion of Capital Stock.  At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent, Merger Sub or the holders of any shares of capital stock of the Company, Parent or Merger Sub:

(a)           Subject to Sections 2.2(b) and 2.3(f), each share of common stock, par value $0.01 per share, of the Company (“Company Common Stock” ) issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock to be canceled in accordance with Section 2.1(b)) shall thereupon be converted automatically into and become exchangeable for, and shall thereafter represent the right to receive, (i) three dollars fifteen cents ($3.15) in cash, without interest, and subject to deduction for any required withholding Tax (the “Cash Consideration”) and (ii) 0.1648 shares of common stock, par value $0.001 per share (“Parent Common Stock”) of Parent (the “Stock Consideration” and, together with the Cash Consideration, the “Merger Consideration”).  As of the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and, subject to Section 2.2(b), shall thereafter only represent the right to receive the Merger Consideration, any dividends or other distributions payable pursuant to Section 2.3(d) and any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f), in each case to be issued or paid in accordance with Section 2.3, without interest.

(b)           Each share of Company Common Stock held in the treasury of the Company or owned, directly or indirectly, by Parent, Merger Sub or any wholly-owned Subsidiary of the Company immediately prior to the Effective Time shall automatically be

3

canceled and shall cease to exist, and, notwithstanding anything in this Agreement to the contrary, no consideration shall be delivered in exchange therefor.

(c)           Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(d)           Each of (x) the Merger Consideration into which each share of Company Common Stock (other than shares of Company Common Stock to be canceled in accordance with Section 2.1(b)) shall be converted automatically and for which each such share shall become exchangeable, and which each such share shall thereafter represent the right to receive, pursuant to Section 2.1(a), and (y) the Company Stock Option Exchange Ratio shall be equitably adjusted, without duplication, to reflect fully the appropriate effect of any stock split (including a reverse stock split) or subdivision or combination, split-up, stock dividend or distribution of securities convertible into Company Common Stock or Parent Common Stock, exchange or readjustment of shares, reorganization, recapitalization, reclassification, merger or other similar transaction, or other like change with respect to the Company Common Stock or Parent Common Stock having a record date occurring on or after the date of this Agreement and prior to the Effective Time; provided, that the ratio of the Cash Consideration (expressed in dollars) per share of Company Common Stock to the Stock Consideration (expressed in number of shares of Parent Common Stock) per share of Company Common Stock shall at all times following any such equitable adjustment be the same as the ratio that the Cash Consideration (expressed in dollars) per share of Company Common Stock bears to the Stock Consideration (expressed in number of shares of Parent Common Stock) per share of Company Common Stock, as set forth in Section 2.1(a); provided further, that nothing in this Section 2.1(d) shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

Section 2.2             Treatment of Company Stock Options, Company Restricted Stock, Employee Stock Purchase Plan and Other Company Stock Plans.

(a)           Treatment of Company Stock Options.  At the Effective Time, each option (each, a “Company Stock Option”) to purchase shares of Company Common Stock granted under any employee or director stock option, stock purchase or equity incentive or equity compensation plan, arrangement or agreement of the Company other than the Company ESPP (the “Company Stock Plans”), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall, at the Effective Time, cease to represent a right to acquire shares of Company Common Stock and shall be converted, at the Effective Time, into an option to purchase shares of Parent Common Stock (a “Parent Option”), on the same terms and conditions (including any vesting or forfeiture provisions or repurchase rights, but taking into account any acceleration thereof provided for in the applicable Company Plan, related award document or any other agreement) as were applicable under such Company Stock Option as of immediately prior to the Effective Time.  The number of shares of Parent Common Stock subject to each such Parent Option shall be equal to (i) the number of shares of Company Common Stock subject to the related Company Stock Option immediately prior

4

to the Effective Time multiplied by (ii) the Company Stock Option Exchange Ratio, rounded down, if necessary, to the nearest whole share of Parent Common Stock, and such Parent Option shall have an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of Company Common Stock otherwise purchasable pursuant to such Company Stock Option divided by (B) the Company Stock Option Exchange Ratio; provided, that in the case of any Company Stock Option to which Section 421 of the Code applies as of the Effective Time (taking into account the effect of any accelerated vesting thereof, if applicable) by reason of its qualification under Section 422 of the Code, the exercise price, the number of shares of Parent Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 424(a) of the Code; provided further, that in the case of any Company Stock Option to which Section 409A of the Code applies as of the Effective Time, the exercise price, the number of shares of Parent Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 409A of the Code; and provided further, that to the extent the option conversion method described herein would cause (x) the issuance of shares of Parent Common Stock by Parent pursuant to the transactions contemplated by this Agreement to be subject to the approval of the holders of Parent Common Stock pursuant to NASDAQ Listing Rule 5635 or (y) the conversion of Company Stock Options under this Section into Parent Options to acquire in excess of 2,500,000 shares of Parent Common Stock, then (1) the number of shares of Parent Common Stock subject to each Parent Option shall be proportionately reduced to the extent necessary to avoid the results described in clauses (x) and (y) above and (2) the per share exercise price of each such Parent Option shall be reduced to the extent necessary to preserve the intrinsic value of the related Company Stock Option as determined immediately prior to the Effective Time.  For purposes of this Agreement, the “Company Stock Option Exchange Ratio” shall equal the sum of (x) (A) $3.15 divided by (B) the volume weighted average of the daily closing prices per share of Parent Common Stock on NASDAQ for the five (5) consecutive trading days ending on and including the trading day immediately preceding the Effective Time, as reported (by Bloomberg Financial Markets) in composite transactions for NASDAQ, plus (y) the number of shares of Parent Common Stock to which each share of Company Common Stock is entitled under Section 2.1(a) (as the same may be adjusted pursuant to Section 2.1(d)).

(b)           Treatment of Company Restricted Stock.  Notwithstanding any provision of this Agreement to the contrary, the Merger Consideration into which each share of Company Restricted Stock (other than shares of Company Common Stock to be canceled in accordance with Section 2.1(b)) shall be converted automatically and for which each such share shall become exchangeable, and which each such share shall thereafter represent the right to receive, pursuant to Section 2.1(a), shall be paid without interest and shall be subject to the same terms and conditions (including any vesting or forfeiture provisions or repurchase rights, but taking into account any acceleration thereof provided for in the applicable Company Plan, related award document or any other agreement).  Therefore, the Cash Consideration payable pursuant to this Article II in exchange for such Company Restricted Stock issued and outstanding immediately before the Effective Time (the “Unvested Cash Consideration” and, together with the Stock Consideration issuable pursuant to this Article II in exchange for such Company Restricted Stock, the “Unvested Merger Consideration”) shall not automatically be payable at the Effective Time and shall instead become payable upon the

5

date such Company Restricted Stock would have become vested under the vesting schedule in place for such shares immediately prior to the Effective Time (subject to the same terms and conditions (including any vesting or forfeiture provisions or repurchase rights, but taking into account any acceleration thereof provided for in the applicable Company Plan, related award document or any other agreement).  Parent shall make all such required payments to former holders of Company Restricted Stock no later than the fifteenth (15th) day of the calendar month immediately following the calendar month in which the Unvested Cash Consideration shall become vested and payable in accordance with this Section, and in its discretion may make such payments through a paying or exchange agent authorized by Parent to administer such payments on Parent’s behalf.  All amounts payable pursuant to this Section shall be subject to any required withholding of Taxes and shall be paid without interest.  All outstanding rights to repurchase Company Restricted Stock that the Company may hold or similar restrictions in the Company’s favor in effect immediately before the Effective Time (all such rights, the “Repurchase Rights”) are hereby assigned to Parent in the Merger, effective as of the Effective Time, and shall thereafter be exercisable by Parent upon the same terms and subject to the same conditions as were in effect immediately before the Effective Time, except that Repurchase Rights may be exercised by Parent retaining the remaining unpaid Unvested Merger Consideration into which such Company Restricted Stock has been converted, and paying to the former holder thereof the repurchase price in effect for each such share subject to that Repurchase Right.  No Unvested Merger Consideration, or the right thereto, may be pledged, encumbered, sold, assigned or transferred (including any transfer by operation of law), by any Person, other than Parent, or be taken or reached by any legal or equitable process in satisfaction of any Liability of such Person, before the distribution to such Person of such Unvested Merger Consideration, in accordance with this Agreement.  For purposes of this Agreement, “Company Restricted Stock” means any Company Common Stock that is not vested under the terms of any Company Stock Plan or any Contract with the Company (including any restricted stock agreement, stock option agreement, stock option exercise agreement or restricted stock purchase agreement) as of immediately before the Effective Time.  The exchange of shares of Company Restricted Stock in partial consideration for the Unvested Cash Consideration, and the vesting and payment of such Unvested Cash Consideration, are intended to comply with Section 409A of the Code and the regulations and other IRS guidance promulgated thereunder.

(c)           Certain Actions Relating to Company Stock Options and Company Restricted Stock.

(i)            Prior to the Effective Time, the Company shall deliver all required notices (which notices shall have been approved by Parent, which approval shall not be unreasonably withheld, conditioned or delayed) to each holder of Company Stock Options and Company Restricted Stock setting forth each holder’s rights pursuant to the applicable Company Stock Plan, stating that such Company Stock Options and Company Restricted Stock shall be treated in the manner set forth in this Section 2.2.

(ii)           Prior to the Effective Time, Parent and the Company shall take all action necessary for the adjustment of the Company Stock Options and Company Restricted Stock under this Section 2.2.  The Company shall ensure that following the Effective Time, no current or former holder of a Company Stock Option, any Company

6

Restricted Stock or a participant in any Company Stock Plan shall have any right thereunder to acquire, or other rights in respect of, any capital stock of the Company or the Surviving Corporation or any of their Subsidiaries or any other equity interest therein (including any Company Stock Option, Company Restricted Stock, “phantom” stock or stock appreciation rights), other than those rights specifically provided for in this Section 2.2.

(iii)          Parent shall reserve for issuance a number of shares of Parent Common Stock at least equal to the number of shares of Parent Common Stock that will be subject to Parent Options as a result of the actions contemplated by this Section 2.2.  As soon as practicable, but not later than five Business Days, following the Effective Time, Parent shall file a registration statement on Form S-8 (or any successor form, or if Form S-8 is not available, other appropriate forms) with respect to offers and sales of the shares of Parent Common Stock subject to such Parent Options and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Parent Options remain outstanding and the offers and sales of Common Stock thereunder are required to be registered.  In connection with the transactions contemplated by this Section 2.2, at the Effective Time, Parent may (if Parent determines that it desires to do so) assume any or all of the Company Stock Plans, provided that, if Parent elects to assume any Company Stock Plan, then, except as expressly provided in Section 2.2(a) or Section 2.2(b) with respect to Parent Options and shares of Parent Common Stock to be issued in exchange for Company Restricted Stock, notwithstanding any provision of such Company Stock Plan, Parent shall not be entitled to grant any stock awards, whether or not permissible under applicable Law, using the share reserves of such Company Stock Plan and, as of the Effective Time, all such then-ungranted shares that were reserved for issuance under such Company Stock Plan shall thereafter be deemed not to be reserved for issuance and no such shares shall be issued or issuable under such Company Stock Plan.  To the extent any Parent Options or shares of Parent Common Stock are issued as provided for in Section 2.2(a) or Section 2.2(b) and such issuance is under such Company Stock Plan, (A) stock covered by such awards shall be shares of Parent Common Stock as provided in Section 2.2(a) and Section 2.2(b); (B) subject to the proviso in the immediately preceding sentence, all references in such Company Stock Plan to a number of shares of Company Common Stock shall be deemed amended to refer instead to a number of shares of Parent Common Stock determined by multiplying the number of referenced shares of Company Common Stock by the Company Stock Option Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; and (C) the Parent Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to the administration of such Company Stock Plan.

(d)           Treatment of Employee Stock Purchase Plan.  The current offerings in progress as of the date hereof under the Company’s 2007 Employee Stock Purchase Plan, as amended (the “Company ESPP”), shall continue, and the shares of Company Common Stock shall be issued to participants thereunder on the next currently scheduled purchase dates thereunder occurring after the date hereof, subject to the terms and conditions of, the Company ESPP.  In accordance with the terms of the Company ESPP, any offering in progress as of the Effective Time shall be shortened, and the “Exercise Date” (as defined in the Company ESPP) shall be the Business Day immediately preceding the Effective Time.

7

Each then outstanding option under the Company ESPP shall be exercised automatically on such Exercise Date.  Notwithstanding any restrictions on transfer of stock in the Company ESPP, the treatment in the Merger of any stock under this provision shall be in accordance with Section 2.1.  The Company shall terminate the Company ESPP as of or prior to the Effective Time.  The Company shall promptly after the date hereof amend the Company ESPP as appropriate to avoid the commencement of any new offering of options thereunder at or after the date hereof and prior to the earlier of the termination of this Agreement or the Effective Time.

Section 2.3             Exchange and Payment.

(a)           Promptly after the Effective Time (but in no event later than the Business Day immediately following the Effective Time), Parent shall deposit (or cause to be deposited, including amounts deposited by the Company as contemplated by Section 5.13(a)) with a bank or trust company designated by Parent in writing to the Company within 45 days after the date of this Agreement and reasonably acceptable to the Company (the “Exchange Agent”), in trust for the benefit of holders of shares of Company Common Stock, (i) cash in an amount sufficient to pay the aggregate Cash Consideration in accordance with Section 2.1 and (ii) book-entry shares representing the shares of Parent Common Stock issuable pursuant to Section 2.1.  In addition, Parent shall make available by depositing with the Exchange Agent, as necessary from time to time on or after the Effective Time, any dividends or distributions payable pursuant to Section 2.3(d) and any additional cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f).  All certificates representing shares of Parent Common Stock, dividends, distributions and cash deposited with the Exchange Agent are hereinafter referred to as the “Exchange Fund.”  Notwithstanding the foregoing or any other provision of this Agreement, Parent shall not be required to deposit or cause to be deposited with the Exchange Agent, as part of the Exchange Fund or otherwise, any Merger Consideration, or any dividends or distributions payable pursuant to Section 2.3(d) or any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f), that constitutes Unvested Merger Consideration pursuant to Section 2.2(b), and no such cash, dividends or distributions shall be payable with respect to Company Restricted Stock (including by the Exchange Agent) except in accordance with Section 2.2(b).  The Exchange Fund shall not be used for any purpose other than to fund payments of cash and shares of Parent Common Stock due pursuant to Section 2.1, except as provided in this Agreement.

(b)           As soon as reasonably practicable after the Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of an outstanding certificate or outstanding certificates (“Certificates”) that immediately prior to the Effective Time represented outstanding shares of Company Common Stock that were converted into the right to receive the Merger Consideration with respect thereto, any dividends or distributions payable pursuant to Section 2.3(d) and any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f), (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such Person shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and which letter shall be in customary form and contain such other provisions as Parent or the Exchange Agent may reasonably specify) and (ii) instructions for

8

use in effecting the surrender of such Certificates in exchange for the Merger Consideration payable with respect thereto, any dividends or other distributions payable pursuant to Section 2.3(d) and any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f).  Upon surrender of a Certificate to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as the Exchange Agent may reasonably require, the holder of such Certificate shall be entitled to receive in exchange therefor (A) a check or wire transfer (at the election of Parent or the Exchange Agent) for the amount of Cash Consideration to which such holder of Company Common Stock shall have become entitled pursuant to the provisions of Section 2.1, (B) that number of whole shares of Parent Common Stock (after taking into account all shares of Company Common Stock then held by such holder under all Certificates so surrendered) to which such holder of Company Common Stock shall have become entitled pursuant to the provisions of Section 2.1 (which shares of Parent Common Stock shall be in uncertificated book-entry form), (C) any dividends or other distributions payable pursuant to Section 2.3(d) and (D) any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f), and the Certificate so surrendered shall forthwith be canceled.  Promptly after the Effective Time and in any event not later than the third Business Day following the Effective Time, the Exchange Agent shall issue and deliver to each holder of uncertificated shares of Company Common Stock represented by book entry (“Book-Entry Shares”) (1) a wire transfer (if such holder has previously provided its wire transfer information to the Exchange Agent in connection with the Merger) or check (if such holder has not previously provided its wire transfer information to the Exchange Agent in connection with the Merger) for the amount of Cash Consideration to which such holder of Book-Entry Shares shall have become entitled pursuant to the provisions of Section 2.1, (2) that number of whole shares of Parent Common Stock to which such holder of Book-Entry Shares shall have become entitled pursuant to the provisions of Section 2.1 (which shares of Parent Common Stock shall be in book-entry form), (3) any dividends or other distributions payable pursuant to Section 2.3(d) and (4) any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f), without such holder being required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent, and such Book-Entry Shares shall then be canceled.  No interest will be paid or accrued on any Cash Consideration, unpaid dividends and distributions or cash in lieu of fractional shares, if any, payable to holders of Certificates or Book-Entry Shares.  Until surrendered as contemplated by this Section 2.3, each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration payable in respect of shares of Company Common Stock theretofore represented by such Certificate or Book-Entry Share, any dividends or other distributions payable pursuant to Section 2.3(d) and any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f).

(c)           If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Share is registered, it shall be a condition of payment that such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer or such Book-Entry Share shall be properly transferred and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate or Book-Entry Share surrendered or shall

9

have established to the satisfaction of Parent that such Tax either has been paid or is not applicable.

(d)           (i)            No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock that the holder thereof has the right to receive upon the surrender thereof, and no cash payment in lieu of fractional shares of Parent Common Stock shall be paid to any such holder pursuant to Section 2.3(f), in each case until the holder thereof shall surrender such Certificate in accordance with this Article II.  Following the surrender of a Certificate in accordance with this Article II, there shall be paid to the record holder thereof, without interest, (A) promptly after such surrender, the amount of any dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.3(f) and (B) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

(ii)           Notwithstanding anything in the foregoing to the contrary, holders of Book-Entry Shares who are entitled to receive shares of Parent Common Stock under this Article II shall be paid (A) at the time of payment of such Parent Common Stock by the Exchange Agent under Section 2.3(b), the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock, and the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.3(f) and (B) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to the time of such payment by the Exchange Agent under Section 2.3(b) and a payment date subsequent to the time of such payment by the Exchange Agent under Section 2.3(b) payable with respect to such whole shares of Parent Common Stock.

(e)           The Merger Consideration, any dividends or other distributions payable pursuant to Section 2.3(d) and any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f) issued and paid upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this Article II shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificates or Book-Entry Shares.  At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time.  If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for transfer or transfer is sought for Book-Entry Shares, such Certificates or Book-Entry Shares shall be canceled and exchanged as provided in this Article II.

10

(f)            Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares, no dividends or other distributions with respect to the Parent Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Parent.  In lieu of the issuance of any such fractional share, Parent shall pay to each former shareholder of the Company who otherwise would be entitled to receive a fractional share of Parent Common Stock an amount in cash (without interest) determined by multiplying (i) the fraction of a share of Parent Common Stock which such holder would otherwise be entitled to receive (taking into account all shares of Company Common Stock held at the Effective Time by such holder and rounded to the nearest thousandth when expressed in decimal form) pursuant to Section 2.1 by (ii) the volume weighted average closing price of one share of Parent Common Stock on The NASDAQ Global Select Market (“NASDAQ”) for the ten trading days ending on the last trading day immediately prior to the date on which the Effective Time shall occur, as such price is reported (by Bloomberg Financial Markets or such other source as the parties shall agree in writing) in composite transactions for NASDAQ.

(g)           Any portion of the Exchange Fund (any interest or other income earned thereon) that remains undistributed to the holders of Certificates or Book-Entry Shares one year after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Certificates or Book-Entry Shares who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws), as general creditors thereof, for payment of the Merger Consideration, any unpaid dividends or other distributions payable pursuant to Section 2.3(d) and any cash in lieu of fractional shares of Parent Common Stock payable pursuant to Section 2.3(f).

(h)           None of Parent, the Surviving Corporation, the Exchange Agent or any other Person shall be liable to any Person in respect of Merger Consideration, dividends or other distributions with respect thereto or cash in lieu of fractional shares of Parent Common Stock properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(i)            The Exchange Agent shall invest any cash included in the Exchange Fund as reasonably directed by Parent; provided, however, that any investment of such cash shall in all events be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government.  Any interest and other income resulting from such investments shall be paid to Parent, upon demand.

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as set forth in the disclosure letter delivered by the Company to Parent prior to the execution of this Agreement (which shall be arranged in numbered and lettered sections corresponding to the numbered and lettered Sections in this Agreement and which disclosure in any such section shall be deemed to qualify and apply to other Sections in this Agreement to the extent that it is reasonably apparent from the face of such disclosure that such disclosure also qualifies or applies to such other Sections) (the “Company Disclosure Letter”), the Company represents and warrants to Parent and Merger Sub as follows:

Section 3.1             Organization, Standing and Power.

(a)           Each of the Company and its Subsidiaries (i) is an entity duly organized, validly existing and in good standing (with respect to jurisdictions that recognize such concept) (it being understood and agreed that “good standing” for purposes of the WBCL means that the Company has filed its most recent annual report and has not filed articles of dissolution) under the Laws of the jurisdiction of its organization, (ii) has all requisite corporate or similar power and authority to own, lease and operate its properties and to carry on its business as now being conducted and (iii) is duly qualified or licensed to do business and is in good standing (with respect to jurisdictions that recognize such concept) in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, except in the case of clause (iii), where the failure to be so qualified or licensed or in good standing, individually or in the aggregate, would not reasonably be expected to have a Company Material Adverse Effect.  For purposes of this Agreement, “Company Material Adverse Effect” means any event, change, circumstance or effect that (A) is materially adverse to the business, condition (financial or otherwise) or results of operations of the Company and its Subsidiaries, taken as a whole, or (B) materially impairs the ability of the Company to consummate, or prevents or

12

materially delays, the Merger or any of the other transactions contemplated by this Agreement; provided, however, that in the case of clause (A) of this definition of “Company Material Adverse Effect” only, Company Material Adverse Effect shall not include any event, change, circumstance or effect (1) generally affecting the industry in which the Company and its Subsidiaries operate, or the economy or the financial or securities markets in the United States, including effects on such industry, economy or markets resulting from any regulatory and political conditions or developments in general, including any outbreak or escalation of hostilities or declared or undeclared acts of war or terrorism and including changes in interest rates; (2) reflecting or resulting from changes in Law or GAAP or accounting standards; (3) demonstrably resulting from the announcement or pendency of the transactions contemplated by this Agreement; (4) any change, in and of itself, in the market price or trading volume of Company Common Stock; (5) changes in any analyst recommendations, any financial strength rating or any other similar recommendations or ratings as to the Company or its Subsidiaries (including, in and of itself, any failure to meet analyst projections); (6) the loss by the Company or any of its Subsidiaries of any of its customers, suppliers or employees as a result of the announcement of the transactions contemplated by this Agreement; (7) the failure, in and of itself, of the Company to meet any expected or projected financial or operating performance target, whether internal or published, for any period ending on or after the date of this Agreement as well as any change, in and of itself, by the Company in backlog or any other expected or projected financial or operating performance target as compared with any target prior to the date of this Agreement; (8) any suit, action or other legal proceeding arising out of or related to this Agreement or (9) any actions taken that are specifically required in accordance with the terms of this Agreement or taken at the written request of Parent or with the prior written consent of Parent; provided, that, with respect to clause (1), the impact of such event, change, circumstance or effect is not disproportionately adverse to the Company and its Subsidiaries, taken as a whole, relative to other participants in the industry in which the Company operates; and provided, further, for the avoidance of doubt, that with respect to clauses (4), (5) and (7), the facts and circumstances giving rise to or contributing to such failure or change may be taken into account in determining whether there has been a Company Material Adverse Effect.

(b)           The Company has made available to Parent true and complete copies of the Company’s amended and restated articles of incorporation (the “Company Charter”) and amended and restated bylaws (the “Company Bylaws”), in each case as amended to the date of this Agreement, and each as so delivered is in full force and effect.  The Company is not in violation of any provision of the Company Charter or Company Bylaws, in each case as amended to the date of this Agreement.

(c)           The Company has made available to Parent true and complete copies of the articles of incorporation and by-laws (or comparable organizational documents) of each of the Company’s Subsidiaries, in each case as amended to the date of this Agreement, and each as so delivered is in full force and effect.  No Subsidiary of the Company is in violation of its articles of incorporation or by-laws (or comparable organizational documents), in each case as amended to the date of this Agreement.

expected to have a Company Material Adverse Effect, and there has occurred no violation of, default (with or without notice or lapse of time or both) under or event giving to others any right of revocation, non-renewal, adverse modification or cancelation of, with or without notice or lapse of time or both, any such Permit, nor would any such revocation, non-renewal, adverse modification or cancelation result from the consummation of the transactions contemplated hereby, except for such violations, defaults, revocations, non-renewals, modifications or cancelations that, individually or in the aggregate, would not reasonably be expected to have a Company Material Adverse Effect.  Notwithstanding anything to the contrary in this Section 3.11(a), no representation or warranty is made in this Section 3.11(a) in respect of the matters referenced in Section 3.12, Section 3.13, Section 3.14, Section 3.15 and Section 3.24.

(b)                                 Neither the Company nor any of its Subsidiaries is subject to any consent decree from any Governmental Entity.  Neither the Company nor any of its Subsidiaries has received any warning or untitled letter from the U.S. Food and Drug Administration (the “FDA”) or equivalent action from any comparable non-U.S. Governmental Entity since May 8, 2007.  Neither the Company nor any of its Subsidiaries has received any communication from any regulatory agency or been notified since May 8, 2007 that any product approval is withdrawn or modified or that such an action is under consideration.  Without limiting the foregoing, the Company and each of its Subsidiaries is in compliance, in all material respects, with all current applicable statutes, rules, regulations, guidelines, policies or orders administered or issued by the FDA, including the Public Health Service Act (“FDA Laws”) or comparable foreign Governmental Entity (“Foreign Device Laws”) including FDA’s Quality System Regulation, 21 C.F.R. Part 820 and requirements for Investigational Device Exemptions, 21 C.F.R. Part 812.  To the knowledge of the Company, there are no facts that would be reasonably likely to result in any Form FDA-483 other than those issues that have been entered into the Company’s corrective and preventive action (CAPA) system, as established within the Company’s quality system.  Since May 8, 2007, there have been no recalls, detentions, withdrawals, seizures, or termination or suspension of manufacturing requested or threatened relating to the Company’s or its Subsidiaries’ products.  Since January 1, 2009, there have been no material field notifications, material field corrections or material alerts.

Part 814 (“PMAs”) for the Company’s and its Subsidiaries’ products are exclusively owned by the Company or one of its Subsidiaries, and there is no reason to believe that the FDA is considering limiting, suspending, or rescinding any such 510(k)s or PMAs or changing the marketing classification or labeling of any such products.  To the knowledge of the Company, there is no false information or significant omission in any product application or product-related submission to the FDA or comparable foreign Governmental Entity.  The Company and its Subsidiaries have obtained all necessary regulatory approvals from any foreign regulatory agencies related to the products distributed and sold by the Company, and the Company has not received any notice that any Governmental Entity seeks any material additional conditions on the distribution or sale of products in a jurisdiction covered by a regulatory approval.  To the knowledge of the

22

Company and its Subsidiaries, any third party that is a manufacturer, contractor, or agent for the Company or its Subsidiaries is in compliance with all Permits and regulatory approvals from the FDA or comparable Governmental Entity insofar as they pertain to the manufacture of product components or products for the Company or its Subsidiaries.

This Section 3.18 does not relate to intellectual property, which is the subject of Section 3.19.

Section 3.19           Intellectual Property.

(a)           For purposes of this Agreement, “Intellectual Property” means any and all intellectual property rights arising from or associated with any of the following, whether protected, created or arising under the laws of the United States or any other jurisdiction:  (i) trade names, trademarks and service marks (registered and unregistered), trade dress and similar rights, and applications (including intent to use applications) to register any of the foregoing (collectively, “Marks”); (ii) domain names and other Internet addresses or identifiers (“Domain Names”), (iii) patents and patent applications (collectively, “Patents”); (iv) copyrights (registered and unregistered) and applications for registration (collectively, “Copyrights”); (v) know-how, inventions, methods, processes, customer lists and any other information or any kind or nature, in each case to the extent any of the foregoing derives economic value (actual or potential) from not being generally known to other Persons who can obtain economic value from its disclosure; and (vi) any other proprietary, intellectual or industrial property rights of any kind or nature.

(b)           Section 3.19 of the Company Disclosure Letter sets forth a true and complete list of all registered Marks, Patents and registered Copyrights, including any pending applications to register any of the foregoing, owned (in whole or in part) by, or exclusively licensed to, the Company or any of its Subsidiaries and that are material to the businesses of the Company or any of its Subsidiaries (collectively, “Company Registered IP”).  Except as, individually or in the aggregate, has not had and would not reasonably be expected to have a Company Material Adverse Effect, (i) all Company Registered IP (other than patent applications or applications to register trademarks) is, to the knowledge of the Company, subsisting, valid and enforceable and (ii) no Company Registered IP is involved in any interference, reissue, reexamination, opposition, cancelation or similar proceeding and, to the knowledge of the Company, no such action is or has been threatened with respect to any of the Company Registered IP.  Except as, individually or in the aggregate, has not had and would not reasonably be expected to have a Company Material Adverse Effect, all Company Registered IP owned by, or filed in the name of,

33

the Company or any of its Subsidiaries and, to the knowledge of the Company, all other Company Registered IP has been registered or obtained in accordance with all applicable legal requirements and is currently in compliance in all respects with all legal requirements (including the timely post-registration filing of affidavits of use and incontestability and renewal applications), and all filing, examination, issuance, post registration and maintenance fees, annuities and the like associated with or required with respect to any of the Company Registered IP owned by, or filed in the name of, the Company or any of its Subsidiaries and, to the knowledge of the Company, any other Company Registered IP, have been timely paid.  No written notice or claim challenging the validity or enforceability or alleging the misuse of any of the Company Registered IP has been received by the Company or any of its Subsidiaries.  Except as, individually or in the aggregate, has not had and would not reasonably be expected to have a Company Material Adverse Effect, the Company has not taken any action or failed to take any action that could reasonably be expected to result in the abandonment, cancelation, forfeiture, relinquishment, invalidation or unenforceability of any of the Company Registered IP.

(c)           Except as, individually or in the aggregate, has not had and would not reasonably be expected to have a Company Material Adverse Effect, the Company or its Subsidiaries own exclusively, free and clear of free and clear of any and all Liens, all Company Registered IP owned by, or filed in the name of, the Company or any of its Subsidiaries and all other Intellectual Property that is material to the businesses of the Company or any of its Subsidiaries other than Intellectual Property owned by a third party that is licensed to the Company or a Subsidiary thereof pursuant to an existing license agreement and used by the Company or such Subsidiary within the scope of such license, and the Company and its Subsidiaries have not received any written notice or claim challenging the Company’s or such Subsidiaries’ ownership of any of such Intellectual Property.

(d)           Each of the Company and its Subsidiaries has taken reasonable steps to protect its rights in its Intellectual Property and to maintain the confidentiality of all information of the Company or its Subsidiaries that derives economic value (actual or potential) from not being generally known to other Persons who can obtain economic value from its disclosure or use.  All current or former employees, consultants and contractors of the Company and its Subsidiaries who have participated in the creation of any Intellectual Property that is used by the Company or any of its Subsidiaries in their respective businesses (excluding any Intellectual Property that is licensed to the Company or any of its Subsidiaries under any license agreement that remains in effect) have entered into reasonable proprietary information, confidentiality and assignment agreements, which the Company has previously made available to Parent.

(e)           To the knowledge of the Company, none of the activities or operations of the Company or any of its Subsidiaries (including the use of any Intellectual Property in connection therewith) have infringed upon, misappropriated or diluted any Intellectual Property of any third party, and neither the Company nor any of its Subsidiaries has received any written notice or claim asserting or suggesting that any such infringement, misappropriation, or dilution is or may be occurring or has or may have occurred, except where any such infringement, misappropriation or dilution, individually or in the aggregate, has not had and would not reasonably be expected to have a Company Material Adverse Effect.  To the Company’s knowledge, no third party is misappropriating, infringing, or diluting in any material respect any Intellectual Property owned by or exclusively licensed to the Company or any of its Subsidiaries that is material to any of the businesses of the Company or any of its Subsidiaries.  No Intellectual Property owned by and, to the knowledge of the Company, no Intellectual Property exclusively licensed to, the Company or any of its Subsidiaries that is material to any of the businesses of the Company or any of its Subsidiaries

34

is subject to any outstanding order, judgment, decree or stipulation restricting or limiting in any material respect the use or licensing thereof by the Company or any of its Subsidiaries.

(f)            Except as set forth on Section 3.19 of the Company Disclosure Letter, the execution, delivery and performance by the Company of this Agreement, and the consummation of the transactions contemplated hereby, will not result in the loss of, or give rise to any right of any third party to terminate or modify any of the Company’s or any Subsidiaries’ rights or obligations under any agreement under which Intellectual Property is licensed to or by the Company or any of its Subsidiaries and that is material to any of the businesses of the Company or any of its Subsidiaries.  All milestones and other conditions required to be satisfied under any license agreements under which Intellectual Property that is material to the business of the Company or any of its Subsidiaries is exclusively licensed to the Company or any of its Subsidiaries (“Exclusive Inbound License Agreements”) in order for the Company or any of its Subsidiaries to retain any exclusive rights granted thereunder have been satisfied in accordance with the terms of such Exclusive Inbound License Agreements, and all such exclusive rights remain in full force and effect.  To the knowledge of the Company, there is no outstanding or threatened dispute or disagreement with respect to any Exclusive Inbound License Agreement that would reasonably be expected to materially affect any of the respective rights and obligations of the parties thereunder.  Neither the Company nor any of its Subsidiaries has transferred ownership of, or granted any exclusive license with respect to, any Intellectual Property that is or was material to the business of the Company or any of its Subsidiaries.  At the Effective Time, Parent, through its ownership of the Surviving Corporation, shall indirectly hold all of the material Intellectual Property rights that the Company and its Subsidiaries held immediately prior to the Effective Time, and all of such rights shall be exercisable by the Surviving Corporation and its Subsidiaries following the Effective Time to the same extent as by the Company and its Subsidiaries prior to the Effective Time.

(g)           The Company owns or has the right to license any Intellectual Property that relates to the business of the Company as operated on the date of this Agreement and that was developed by Thomas Rockwell Mackie, Gustavo Olivera or any other employee of the Company or any of its Subsidiaries during any period in which such individual served both as an employee of the University of Wisconsin or the Wisconsin Alumni Research Foundation, on the one hand, and as an employee, consultant or independent contractor of the Company or any of its Subsidiaries, on the other hand.

Section 3.20           Product Warranties.

(a)           Section 3.20(a) of the Company Disclosure Letter contains copies of the standard form product warranties (including all warranty, refund, product support or product maintenance obligations) offered by the Company and its Subsidiaries to direct customers, distributors and other Persons.  All product warranties (including all warranty, refund, product support or product maintenance obligations) of the Company and its Subsidiaries currently in effect are in all material respects in the form of such standard form product warranties.

35

(b)           Except as would be consistent with the claims experience of the Company in the ordinary course of business, to the knowledge of the Company, there is no basis for any warranty, material back-charge, material additional work, field repair or other such warranty and workmanship claims or other product liability claims by any third party against the Company or any of its Subsidiaries associated with the Company’s or its Subsidiaries’ products shipped prior to the Effective Time.

Section 3.21           State Takeover Statutes.  The Company has, or will have prior to the Effective Time, taken all necessary action so that, assuming compliance by Parent and Merger Sub with their respective obligations hereunder and the accuracy of the representations and warranties made by Parent and Merger Sub, no “moratorium,” “fair price,” “business combination,” “control share acquisition” or similar provision of any state anti-takeover Law (collectively, “Takeover Laws”) is, or at the Effective Time will be, applicable to this Agreement, the Merger or any of the other transactions contemplated hereby.

Section 3.22           No Rights Plan.  There is no shareholder rights plan, “poison pill” anti-takeover plan or other similar device in effect to which the Company is a party or is otherwise bound.

Section 3.23           Related Party Transactions.  No present or former director or executive officer of the Company, nor any Person beneficially owning a number of shares of Company Common Stock constituting more than 5% of all issued and outstanding shares of Company Common Stock, nor any of such Person’s immediate family members (as defined in Item 404 of Regulation S-K), has been a participant in any transaction or proposed transaction with the Company or any of its Consolidated Subsidiaries within the last 12 months, in each case, that is of a type that would be required to be disclosed in the Company SEC Documents pursuant to Item 404 of Regulation S-K that has not been so disclosed.

Section 3.24           Certain Payments.  Neither the Company nor any of its Subsidiaries (nor, to the knowledge of the Company, any of their respective directors, executives, representatives, agents or employees) (a) has used or is using any corporate funds for any illegal contributions, gifts, entertainment or other unlawful expenses relating to political activity, (b) has used or is using any corporate funds for any direct or indirect unlawful payments to any foreign or domestic governmental officials or employees, (c) has violated or is violating any provision of the Foreign Corrupt Practices Act of 1977, (d) has established or maintained, or is maintaining, any unlawful fund of corporate monies or other properties or (e) has made or offered any unlawful bribe, rebate, payoff, influence payment, kickback or similar unlawful payment of any nature.

Section 3.25           Export Compliance.

(a)           To the knowledge of the Company, the Company and each of its Subsidiaries have conducted their export transactions in accordance in all material respects with applicable provisions of U.S. export Laws (including the International Traffic in Arms regulations, the Export Administration Regulations and the regulations administered by the Department of Treasury, Office of Foreign Assets Control (“OFAC”)), and other export Laws of the countries where it conducts business, and neither the Company nor any of its

Section 3.26           CPAC.  The entry into this Agreement and the consummation of the transactions contemplated hereby, have not resulted in and will not, pursuant to the terms of any Contracts relating to CPAC to which the Company or any of its Subsidiaries is a party, result in any material violation or breach of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of, or result in, termination, cancelation, modification or acceleration of any obligation or to the loss of a material benefit under any such Contract relating to CPAC.  As of the date of this Agreement, there is no material Action pending or, to the knowledge of the Company, threatened against CPAC or any of its Subsidiaries, or involving any investors in CPAC, whether or not relating to the transactions contemplated by this Agreement.

Section 3.27           Brokers.  No broker, investment banker, financial advisor or other Person, other than Merrill Lynch, Pierce, Fenner & Smith Incorporated (“BAML”), the fees and expenses of which will be paid by the Company, is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of the Company or any of its Affiliates.   The Company has not entered into any Contract with BAML or any of its Affiliates that would obligate Parent or the Company to retain BAML or any of its Affiliates to perform any investment banking, underwriting or other services following the Effective Time.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF

PARENT AND MERGER SUB

Except as set forth in the disclosure letter delivered by Parent to the Company prior to the execution of this Agreement (which shall be arranged in numbered and lettered sections corresponding to the numbered and lettered Sections in this Agreement and which disclosure in any such section shall be deemed to qualify and apply to other Sections in this Agreement to the extent that it is reasonably apparent from the face of such disclosure that such disclosure also qualifies or applies to such other Sections) (the “Parent Disclosure Letter”), Parent and the Merger Sub represent and warrant to the Company as follows:

Section 4.1                                      Organization, Standing and Power.

(a)                                  Each of Parent and its Subsidiaries (i) is an entity duly organized, validly existing and in good standing (with respect to jurisdictions that recognize such concept) (it being understood and agreed that “good standing” for purposes of the WBCL means that Merger Sub has filed its most recent annual report and has not filed articles of dissolution) under the Laws of the jurisdiction of its organization, (ii) has all requisite corporate or similar power and authority to own, lease and operate its properties and to carry on its business as now being conducted and (iii) is duly qualified or licensed to do business and is in good standing (with respect to jurisdictions that recognize such concept) in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, except in the case of clause (iii), where the failure to be so qualified or licensed or in good standing, individually or in the aggregate, would not reasonably be expected to have a Parent Material Adverse Effect.  For purposes of this Agreement, “Parent Material Adverse Effect” means any event, change, circumstance or effect that (A) is materially adverse to the business, condition (financial or otherwise) or results of operations of Parent and its Subsidiaries, taken as a whole, or (B) materially impairs the ability of Parent or Merger Sub to consummate, or prevents or materially delays, the Merger or any of the other transactions contemplated by this Agreement; provided, however, that in the case of clause (A) of this definition of “Parent Material Adverse Effect” only, Parent Material Adverse Effect shall not include any event,

38

change, circumstance or effect (1) generally affecting the industry in which Parent and its Subsidiaries operate, or the economy or the financial or securities markets in the United States, including effects on such industry, economy or markets resulting from any regulatory and political conditions or developments in general, including any outbreak or escalation of hostilities or declared or undeclared acts of war or terrorism and including changes in interest rates; (2) reflecting or resulting from changes in Law or GAAP or accounting standards; (3) demonstrably resulting from the announcement or pendency of the transactions contemplated by this Agreement; (4) any change, in and of itself, in the market price or trading volume of Parent Common Stock; (5) changes in any analyst recommendations, any financial strength rating or any other similar recommendations or ratings as to Parent or its Subsidiaries (including, in and of itself, any failure to meet analyst projections); (6) the loss by Parent or any of its Subsidiaries of any of its customers, suppliers or employees as a result of the announcement of the transactions contemplated by this Agreement; (7) the failure, in and of itself, of Parent to meet any expected or projected financial or operating performance target, whether internal or published, for any period ending on or after the date of this Agreement as well as any change, in and of itself, by Parent in backlog or any other expected or projected financial or operating performance target as compared with any target prior to the date of this Agreement; (8) any suit, action or other legal proceeding arising out of or related to this Agreement or (9) any actions taken that are specifically required in accordance with the terms of this Agreement or taken at the written request of the Company or with the prior written consent of the Company; provided, that, with respect to clause (1), the impact of such event, change, circumstance or effect is not disproportionately adverse to Parent and its Subsidiaries, taken as a whole, relative to other participants in the industry in which Parent operates; and provided, further, for the avoidance of doubt, that with respect to clauses (4), (5) and (7), the facts and circumstances giving rise to or contributing to such failure or change may be taken into account in determining whether there has been a Parent Material Adverse Effect.

(b)                                 Parent has previously made available to the Company true and complete copies of Parent’s certificate of incorporation and bylaws, in each case as amended to the date of this Agreement, and each as so delivered is in full force and effect.  Parent is not in violation of any provision of its certificate of incorporation or bylaws, in each case as amended to the date of this Agreement.

(c)                                  Parent has previously made available to the Company true and complete copies of the certificate of incorporation and by-laws (or comparable organizational documents) of each of its Subsidiaries, in each case as amended to the date of this Agreement, and each as so delivered is in full force and effect.  No Subsidiary of Parent is in violation of its certificate of incorporation or by-laws (or comparable organizational documents), in each case as amended to the date of this Agreement.

Section 4.3                                      Authority.

(a)                                  Each of Parent and Merger Sub has all necessary corporate power and authority to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby.  The execution, delivery and performance of this Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Parent and Merger Sub, and no other corporate proceedings on the part of Parent or Merger Sub are necessary to approve and adopt this Agreement or to consummate the transactions contemplated hereby.  This Agreement has been duly executed and delivered by Parent and Merger Sub and, assuming the due authorization, execution and delivery by the Company, constitutes a valid and binding obligation of each of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms (except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar Laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity).

(c)                           Notwithstanding the foregoing Sections 5.2(a) and (b), if at any time following the date of this Agreement and prior to obtaining the Company Shareholder Approval, (1) the Company receives a written Acquisition Proposal that the Company Board believes in good faith to be bona fide, (2) such Acquisition Proposal did not result from a breach of this Section 5.2, (3) the Company Board determines in good faith (after consultation with outside counsel and its financial advisor) that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (4) the Company Board determines in good faith (after consultation with outside counsel) that the failure to take the actions referred to in clause (x) or (y) below is reasonably likely to constitute a breach of its fiduciary duties to the shareholders of the Company under applicable Law, then the Company may (x) furnish information with respect to the Company and its Subsidiaries to the Person making such Acquisition Proposal pursuant to a customary confidentiality agreement containing terms substantially similar to, and no less favorable to the Company than, those set forth in the

57

Confidentiality Agreement (provided, that any non-public information provided to any Person given such access shall have been previously provided to Parent or shall be provided to Parent prior to or concurrently with the time it is provided to such Person) and (y) participate in discussions or negotiations with the Person making such Acquisition Proposal regarding such Acquisition Proposal.

(ii)           (A) cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract (each, an “Alternative Acquisition Agreement”) constituting or related to, or which is intended to or is reasonably likely to lead to, any Acquisition Proposal or (B) resolve, agree or propose to take any such actions.

(e)                           Notwithstanding the foregoing Sections 5.2(d)(i) and (d)(ii), at any time prior to obtaining the Company Shareholder Approval, the Company Board may, solely in response to a Superior Proposal received after the date hereof that did not result from a breach of this Section 5.2, if the Company Board determines in good faith (after consultation with outside counsel) that the failure to do so is reasonably likely to result in a breach of its fiduciary duties to the shareholders of the Company under applicable Law, taking into account all adjustments to the terms of this Agreement that may be offered by Parent pursuant to this Section 5.2(e), (x) make an Adverse Recommendation Change or (y) cause the Company to terminate this Agreement pursuant to Section 7.1(d)(ii) (including payment of the Termination Fee) and concurrently enter into a binding Alternative Acquisition Agreement with respect to such Superior Proposal; provided, however, that the Company may not make an Adverse Recommendation Change or terminate this Agreement in response to a Superior Proposal as referred to above unless (1) the Company promptly notifies Parent in writing at least four Business Days before taking that action of its intention to do so, and specifying the reasons therefor, including the terms and conditions of, and the identity of any Person making, such Superior Proposal, and contemporaneously furnishing a copy of the relevant Alternative Acquisition Agreement and any other relevant transaction documents (it being understood and agreed that any amendment to the financial terms or any other material term of such Superior Proposal shall require a new written notice by the Company and a new four Business Day period) and (2) prior to the expiration of such four Business Day period, Parent does not make a proposal to adjust the terms and conditions of this Agreement that the Company Board determines in good faith (after consultation with outside counsel and its financial advisor) to be at least as favorable as the Superior Proposal after giving effect to,

58

among other things, the payment of the Termination Fee set forth in Section 7.3, such that the Company Board determines such action is no longer required by its fiduciary duties to the shareholders of the Company under applicable Law.  During the four Business Day period prior to its effecting an Adverse Recommendation Change or terminating this Agreement as referred to above, the Company shall, and shall cause its financial and legal advisors to, negotiate with Parent in good faith (to the extent Parent seeks to negotiate) regarding any revisions to the terms of the transactions contemplated by this Agreement proposed by Parent.

(f)            In addition to the obligations of the Company set forth in Sections 5.2(a), (b), (c), (d) and (e), the Company promptly, and in any event within one Business Day of receipt (unless such receipt is by any director or executive officer of the Company or a director an executive officer has knowledge of such receipt by the Company, in which case such one Business Day period shall instead be deemed to be a 24 hour period from the time of such receipt by, or the time such knowledge was first gained by, such director or executive officer), shall advise Parent in writing in the event the Company or any of its Subsidiaries or Representatives receives (i) any Acquisition Proposal or indication by any Person that it is considering making an Acquisition Proposal, (ii) any request for information, discussion or negotiation that is reasonably likely to lead to or that contemplates an Acquisition Proposal or (iii) any inquiry, proposal or offer that is reasonably likely to lead to an Acquisition Proposal, in each case together with the terms and conditions of such Acquisition Proposal, request, inquiry, proposal or offer and the identity of the Person making any such Acquisition Proposal, request, inquiry, proposal or offer, and shall furnish Parent with a copy of such Acquisition Proposal (or, where such Acquisition Proposal is not in writing, with a description of the material terms and conditions thereof).  The Company shall keep Parent informed (orally and in writing) in all material respects on a timely basis of the status and details (including, within one Business Day after the occurrence (or, if a director or an executive officer of the Company was involved in or had knowledge of such occurrence, then within 24 hours of the time of such director or executive officer’s first involvement therein or at which such director or executive officer first gained such knowledge) of any amendment, modification, development, discussion or negotiation by the Company) of any such Acquisition Proposal, request, inquiry, proposal or offer, including furnishing copies of any written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions.  Without limiting any of the foregoing, the Company shall promptly (and in any event within one Business Day or, in the case of any such determination or engagement by any director or executive officer or of which a director or an executive officer has knowledge, then within 24 hours of the time of such determination or engagement or at which such director or executive officer first gained such knowledge) notify Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning an Acquisition Proposal pursuant to Section 5.2(a), (b), (c), (d) or (e) and shall in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice.

(g)           The Company shall not, and shall cause its Subsidiaries not to, enter into any confidentiality agreement with any Person subsequent to the date of this Agreement that would restrict the Company’s ability to comply with any of the terms of this Section 5.2, and represents that neither it nor any of its Subsidiaries is a party to any such agreement.

59

(h)           The Company shall not take any action to exempt any Person (other than Parent, Merger Sub and their respective Affiliates) from the restrictions on “business combinations” contained in Section 180.1141 of the WBCL (or any similar provision of any other Takeover Law) or otherwise cause such restrictions not to apply, or agree to do any of the foregoing, in each case, unless such actions are taken substantially concurrently with a termination of this Agreement pursuant to Section 7.1(d)(ii).

(i)            Nothing contained in this Section 5.2 shall prohibit the Company from taking and disclosing a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act; provided, however, that in no event shall this Section 5.2(i) affect the obligations of the Company specified in Sections 5.2(d) and (f); and provided further, that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Section 14d-9(f) under the Exchange Act) shall be deemed to be an Adverse Recommendation Change (including for purposes of Section 7.1(c)(ii)) unless the Company Board expressly reaffirms its recommendation to its shareholders in favor of the approval and adoption of this Agreement and the transactions contemplated hereby at least two Business Days prior to the Company Shareholders Meeting.

(j)            For purposes of this Agreement:

(i)            “Acquisition Proposal” means any inquiry, proposal or offer from any Person or group of Persons (other than Parent and its Affiliates) relating to, or that is reasonably likely to lead to, any direct or indirect acquisition or purchase, in one transaction or a series of transactions, including any merger, reorganization, consolidation, tender offer, self-tender, exchange offer, stock acquisition, asset acquisition, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture or similar transaction, (A) of assets or businesses of the Company and its Subsidiaries that generate 15% or more of the consolidated net revenues or net income of the Company or that represent 15% or more of the consolidated total assets (based on fair market value), of the Company, immediately prior to such transaction, (B) of 15% or more of any class of capital stock, other equity security or voting power of the Company or any resulting parent company of the Company or (C) involving the Company or any of its Subsidiaries, individually or taken together, whose businesses constitute 15% or more of the consolidated net revenues, net income or total assets (based on fair market value) of the Company, immediately prior to such transaction, in each case other than the transactions contemplated by this Agreement.

(ii)           “Superior Proposal” means any bona fide binding written Acquisition Proposal that the Company Board determines in good faith (after consultation with outside counsel and its financial advisor), taking into account all legal, financial, regulatory and other aspects of the proposal and the Person making the proposal, and which is not subject to any financing condition or, if financing is required, such financing is then fully committed or reasonably determined to be available by the Company Board, (A) is more favorable to the shareholders of the Company from a financial point of view than the transactions contemplated by this Agreement (including any adjustment to the terms and conditions proposed by Parent in response to such proposal pursuant to Section 5.2(e) or otherwise, and including any break-up fees and expense reimbursement provisions) and (B) is

60

reasonably likely to be completed on the terms proposed; provided, that, for purposes of this definition of “Superior Proposal,” references in the term “Acquisition Proposal” to “15%” shall be deemed to be references to “75%.”

Section 5.3             Preparation of Form S-4 and Proxy Statement; Company Shareholders Meeting.

(a)           As promptly as practicable following the date of this Agreement, (i) the Company shall prepare (with Parent’s reasonable cooperation) and file with the SEC a proxy statement (as amended or supplemented from time to time, and including the letter to holders of shares of Company Common Stock, notices of meetings of holders of shares of Company Common Stock, proxy statement and form of proxy and any other soliciting material to be distributed to holders of shares of Company Common Stock in connection with the Merger, and any schedules required to be filed therewith, collectively, the “Proxy Statement”) to be sent to the shareholders of the Company relating to the special meeting or annual meeting of the Company’s shareholders (the “Company Shareholders Meeting”) to be held to consider the approval and adoption of this Agreement and (ii) Parent shall prepare (with the Company’s reasonable cooperation) and file with the SEC a registration statement on Form S-4 (as amended or supplemented from time to time, the “Form S-4”), in which the Proxy Statement will be included, in connection with the registration under the Securities Act of the Parent Common Stock to be issued in the Merger.  Each of the Company and Parent shall use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing and to keep the Form S-4 effective as long as is necessary to consummate the Merger and the other transactions contemplated hereby.  Parent shall also take any action (other than qualifying to do business in any jurisdiction in which it is not now so qualified or filing a general consent to service of process) required to be taken under any applicable state securities or “blue sky” laws in connection with the issuance of shares of Parent Common Stock in the Merger and the Company shall furnish all information concerning the Company and the holders of Company Common Stock as may be reasonably requested in connection with any such action.  The Company shall use reasonable best efforts to cause the Proxy Statement to be mailed to the Company’s shareholders as promptly as practicable after the Form S-4 is declared effective under the Securities Act.  No filing of, or amendment or supplement to, the Form S-4 or the Proxy Statement will be made by Parent or the Company, as applicable, without providing the other a reasonable opportunity to review and comment thereon and without the other’s prior approval (which shall not be unreasonably withheld, conditioned or delayed).  Parent or the Company, as applicable, will advise the other promptly after it receives oral or written notice thereof, of the time when the Form S-4 has become effective or any amendment or supplement thereto has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction or any oral or written request by the SEC for amendment of the Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission and a reasonable opportunity to participate in the responses thereto.  If at any time prior to the Effective Time any information relating to the Company or Parent, or any of their respective Affiliates, officers or directors, should be discovered by the Company or Parent that should be set forth in an amendment or supplement to any of the

61

Form S-4 or the Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall promptly be filed with the SEC and, to the extent required under applicable Law, disseminated to shareholders of the Company; provided that the delivery of such notice and the filing of any such amendment or supplement shall not affect or be deemed to modify any representation or warranty made by any party hereunder or otherwise affect the remedies available hereunder to any party.

(b)           As promptly as practicable after the Form S-4 is declared effective under the Securities Act, the Company shall establish a record date for, duly call, give notice of, convene and hold the Company Shareholders Meeting solely for the purpose of obtaining the Company Shareholder Approval.  Except in the case of an Adverse Recommendation Change specifically permitted by Section 5.2(e), the Company, through the Company Board, shall (i) recommend to its shareholders that they approve and adopt this Agreement and the transactions contemplated hereby, (ii) include such recommendation in the Proxy Statement and (iii) at the request of Parent, publicly reaffirm such recommendation within 10 Business Days after the date any Acquisition Proposal or any material modification thereto is first commenced, published or sent or given to the Company’s shareholders (which reaffirmation must also include, with respect to an Acquisition Proposal, an unconditional rejection of such Acquisition Proposal, it being understood that taking no position with respect to the acceptance of such Acquisition Proposal or modification thereto shall constitute a failure to reject such Acquisition Proposal).

Section 5.4             Access to Information; Confidentiality.

(a)           The Company shall, and shall cause each of its Subsidiaries to, afford to Parent, Merger Sub and their respective Representatives reasonable access during normal business hours, during the period prior to the earlier of Effective Time and the termination of this Agreement in accordance with its terms, to such information, properties and personnel regarding the Company as shall be reasonably necessary for Parent or Merger Sub to fulfill their respective obligations pursuant to this Agreement, to confirm that the representations and warranties of the Company contained herein are true and correct, to confirm that the covenants of the Company contained herein have been performed in all material respects and to enable Parent, subject to applicable Law, to conduct integration planning in connection with, and in preparation for, the Merger, and, during such period, the Company shall, and shall cause each of its Subsidiaries to, also furnish promptly to Parent:  (a) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal or state securities laws and (b) all other information concerning its business, properties and personnel as Parent or Merger Sub may reasonably request (including Tax Returns filed); provided, however, that the foregoing shall not require the Company to disclose any information to the extent such disclosure would contravene applicable Law.  All such information shall be held confidential in accordance with the terms of the Confidentiality Agreement between Parent and the Company dated as of October 31, 2010 (the “Confidentiality Agreement”).  No investigation pursuant to this

67

funds (or intrabank transfer of immediately available funds, if applicable) from the Exchange Fund Account to such account at the Exchange Agent, effective no later than the Business Day immediately following the Effective Time.

(d)                                 In the event that the Company (i) makes the wire transfer required to be made by Section 5.13(a) on a date following the date of satisfaction or, to the extent permitted by applicable Law, waiver of the conditions set forth in Article VI (other than those conditions that by their terms are to be satisfied at the Closing) and (ii) the Closing does not occur within two Business Days following the date by which the Closing is required to take place under Section 1.2, then, notwithstanding any other provision of this Section 5.13, the Company shall no longer be obligated to maintain at least sixty-five million dollars ($65,000,000) in the Exchange Fund Account.

(b)                                 Parent shall, and shall cause the Surviving Corporation and the Affiliates of Parent and the Surviving Corporation, to recognize the service of each Continuing Employee as if such service had been performed with Parent, the Surviving Corporation or such Affiliates for all purposes (including eligibility, participation, vesting and benefit accrual (other than under a defined benefit pension plan)) under each employee benefit plan, policy, program, arrangement or agreement of Parent, the Surviving Corporation or such Affiliate solely to the extent that Parent, the Surviving Corporation or such Affiliate makes such plan, policy, program, arrangement or agreement available to such Continuing Employee, and except as would result in any duplication of benefits for the same period of service.

68

(c)                                  With respect to any welfare plan maintained by Parent or its Affiliates in which Continuing Employees are eligible to participate after the Effective Time, Parent shall, and Parent shall cause the Surviving Corporation and the Affiliates of Parent and the Surviving Corporation to, (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees to the extent such conditions and exclusions were satisfied or did not apply to such employees under the welfare plans of the Company and its Subsidiaries prior to the Effective Time and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any analogous deductible or out of pocket requirements to the extent applicable under any such plan.

(f)                                    As of the Effective Time, each Continuing Employee shall become fully vested in each of his or her accounts maintained under the Company’s Retirement Savings Plan.

(g)                                 Without limiting the scope of Section 8.6, no provision of this Section 5.14 shall create any third-party beneficiary rights in any employee or former employee (including any beneficiary or dependent thereof) of the Company or any of its Subsidiaries in any respect, including in respect of continued employment (or resumed employment) with Parent, the Surviving Corporation or its Subsidiaries or any other Affiliates of Parent, and no provision of this Section 5.14 shall create such rights in any such persons in respect of any benefits that may be provided, directly or indirectly, under any Company Plan or any employee program or any plan or arrangement of Parent or any of its Affiliates.  No provision of this Agreement shall constitute a limitation on the rights to amend, modify or terminate after the Effective Time any such plans or arrangements of Parent, the Company or its Subsidiaries or any other Affiliates of Parent in accordance with the terms of such plans or arrangements.

74

(b)                                 In the event that:

(i)                                     (A) an Acquisition Proposal (whether or not conditional) or intention to make an Acquisition Proposal (whether or not conditional) shall have been (1) made directly to the Company’s shareholders, (2) otherwise publicly disclosed or (3) otherwise communicated to senior management of the Company or the Company Board and, in the case of this clause (3), following a request to do so by Parent, the Company fails to publicly reaffirm its recommendation of this Agreement and the transactions contemplated hereby within 10 Business Days of such request, (B) this Agreement is thereafter terminated by the Company or Parent pursuant to Section 7.1(b)(i) or (b)(iii) or by Parent pursuant to Section 7.1(c)(i) and (C) within 12 months after the date of such termination, the Company enters into an agreement in respect of any Acquisition Proposal, or recommends or submits an Acquisition Proposal to its shareholders for adoption, or a transaction in respect of an Acquisition Proposal is consummated, which, in each case, need not be the same Acquisition Proposal that shall have been made, publicly disclosed or communicated prior to termination hereof (provided, that for purposes of this clause (C), each reference to “15%” in the definition of “Acquisition Proposal” shall be deemed to be a reference to “50%”);

(ii)                                  this Agreement is terminated by Parent pursuant to Section 7.1(c)(ii); or

(c)                                  In the event that this Agreement is terminated by the Company or Parent pursuant to Section 7.1(b)(iii) or by Parent pursuant to Section 7.1(c)(i) under circumstances in which the Termination Fee is not then payable pursuant to Section 7.3(b)(i), then the Company shall reimburse Parent and its Affiliates for all of their reasonable out-of-pocket fees and expenses (including all fees and expenses of financing sources, counsel, accountants, investment bankers, experts and consultants to Parent and Merger Sub and their Affiliates) incurred by Parent or Merger Sub or on their behalf in connection with or related to the authorization, preparation, investigation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby (the “Parent Expenses”), up to a maximum amount of $1,500,000; provided, that the payment by the Company of the Parent Expenses pursuant to this Section 7.3(c) (i) shall not relieve the Company of any subsequent obligation to pay the Termination Fee pursuant to Section 7.3(b)(i) except to the extent indicated in Section 7.3(b) and (ii) shall not relieve the Company from any liability or damage resulting from any fraud or willful or intentional breach of any provision of this Agreement.

(d)                                 Payment of the Termination Fee shall be made by wire transfer of same day funds to the account or accounts designated by Parent (i) on the earliest of the execution of a definitive agreement with respect to, submission to the shareholders of, or consummation

75

of, any transaction contemplated by an Acquisition Proposal, as applicable, in the case of a Termination Fee payable pursuant to Section 7.3(b)(i), (ii) as promptly as reasonably practicable after termination (and, in any event, within two Business Days thereof), in the case of termination by Parent pursuant to Section 7.1(c)(ii) or (iii) simultaneously with, and as a condition to the effectiveness of, termination, in the case of a termination by the Company pursuant to Section 7.1(d)(ii).  Payment of the Parent Expenses shall be made by wire transfer of same day funds to the account or accounts designated by Parent within two Business Days after the Company’s having been notified of the amount thereof by Parent.

(e)                                  The Company acknowledges that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent and Merger Sub would not enter into this Agreement; accordingly, if the Company fails promptly to pay any amounts due pursuant to this Section 7.3, and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for the amounts set forth in this Section 7.3, the Company shall pay to Parent its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts due pursuant to this Section 7.3 from the date such payment was required to be made until the date of payment at the prime lending rate as published in The Wall Street Journal in effect on the date such payment was required to be made.

Section 7.4                                      Amendment or Supplement.  This Agreement may be amended, modified or supplemented by the parties by action taken or authorized by their respective Boards of Directors at any time prior to the Effective Time, whether before or after the Company Shareholder Approval has been obtained; provided, however, that after the Company Shareholder Approval has been obtained, no amendment may be made that pursuant to applicable Law requires further approval or adoption by the shareholders of the Company without such further approval or adoption.  This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each of the parties in interest at the time of the amendment.

Section 7.5                                      Extension of Time; Waiver.  At any time prior to the Effective Time, the parties may, by action taken or authorized by their respective boards of directors, to the extent permitted by applicable Law, (a) extend the time for the performance of any of the obligations or acts of the other parties, (b) waive any inaccuracies in the representations and warranties of the other parties set forth in this Agreement or any document delivered pursuant hereto or (c) subject to applicable Law, waive compliance with any of the agreements or conditions of the other parties contained herein; provided, however, that after the Company Shareholder Approval has been obtained, no waiver may be made that pursuant to applicable Law requires further approval or adoption by the shareholders of the Company without such further approval or adoption.  Any agreement on the part of a party to any such waiver shall be valid only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party.  No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the

76

exercise of any other right or power.  The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder.
