AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

This AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, is made and entered into as of January 24, 2005 and amended as of April 20, 2005 (the “Agreement”), by and among Renaissance Learning, Inc., a Wisconsin corporation (the “Company”), RLI Acquisition Corp., Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”), RLI Acquisition Sub, LLC, a single member Delaware limited liability company and a wholly owned subsidiary of the Company (the “LLC”), and AlphaSmart, Inc., a Delaware corporation (“Seller”).

WHEREAS, the respective Boards of Directors of the Company, Merger Sub and Seller and the manager of the LLC have each determined that it is in the best interests of their respective companies and the shareholders, stockholders or sole member of their respective companies for Merger Sub to merge with and into Seller (the “Step One Merger”) and immediately thereafter for Seller, as the surviving corporation of the Step One Merger (the “Interim Surviving Corporation”), to merge with and into the LLC (the “Step Two Merger,” and together with the Step One Merger, the “Mergers”), with the LLC being the ultimate surviving entity in the Mergers (the “Surviving Company”), upon the terms and subject to the conditions set forth herein and in accordance with the Delaware General Corporation Law, as amended (the “DGCL”), pursuant to which, among other things, the Company will acquire the goodwill of Seller;

WHEREAS, the respective Boards of Directors of the Company, Merger Sub and Seller and the manager of the LLC have each approved the Mergers upon the terms and subject to the conditions set forth herein, and have approved and adopted this Agreement;

WHEREAS, concurrently with the execution of this Agreement and as a condition and an inducement to the willingness of the Company, Merger Sub and the LLC to enter into this Agreement, the Company, Merger Sub and certain stockholders of Seller have entered into agreements (the “Stockholders Voting Agreements”) in the form attached hereto as Exhibit A, pursuant to which each stockholder listed on Exhibit A to such Stockholders Voting Agreement has agreed to grant the Company a proxy to vote their shares of Seller Common Stock (as defined in Section 1.7(a), below) in favor of the Mergers; and

WHEREAS, for federal income tax purposes, it is intended that the Step One Merger and the Step Two Merger each shall constitute steps in one integrated transaction and that the Mergers taken together shall qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement shall constitute a plan of reorganization within the meaning of the regulations promulgated under Section 368(a) of the Code.

NOW, THEREFORE, in consideration of the foregoing premises and the respective representations, warranties, covenants and agreements contained herein, and subject to the terms and conditions set forth herein, the parties hereto hereby agree as follows:

ARTICLE I - THE MERGERS

SECTION 1.1 The Step One Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time (as defined in Section 1.2(b), below), Merger Sub shall be merged with and into Seller. As a result of the Step One Merger, the separate corporate existence of Merger Sub shall cease and Seller, as a direct, wholly owned subsidiary of the Company, shall continue as the Interim Surviving Corporation under the laws of the State of Delaware.

SECTION 1.2 The Closing; Effective Time.

(a) The closing of the Step One Merger and the transactions contemplated hereby (the “Closing”) shall be held at such time, date and location as may be mutually agreed by the parties. In the absence of such agreement, the Closing shall occur as soon as reasonably practical, but in no event later than two (2) business days, following the satisfaction or waiver of the latest to occur of the conditions set forth in Article VII, at the offices of ▇▇▇▇▇▇▇ & ▇▇▇▇, S.C., ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, commencing at 9:00 a.m. Central Time, or at such other date, time and location as the parties hereto agree to in writing.

(b) As promptly as practicable on the date of the Closing, the parties hereto shall cause the Step One Merger to be consummated by filing a certificate of merger (the “Certificate of Merger”) and any other required documents with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”), in such form as required by, and executed in accordance with the relevant provisions of, the DGCL. The Step One Merger will become effective at such time as the Certificate of Merger is filed with the Delaware Secretary of State, or at such later time as the Company, Merger Sub, the LLC and Seller agree and specify in the Certificate of Merger (the date and time the Step One Merger becomes effective is referred to herein as the “Effective Time”).

SECTION 1.3 Effect of the Step One Merger. From and after the Effective Time, the effect of the Step One Merger shall be as provided in this Agreement, the Certificate of Merger and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers and franchises of Merger Sub and Seller shall vest in the Interim Surviving Corporation, and all debts, liabilities and duties of Merger Sub and Seller shall become the debts, liabilities and duties of the Interim Surviving Corporation.

SECTION 1.4 Certificate of Incorporation and By-Laws. The certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, will be the certificate of incorporation of the Interim Surviving Corporation until thereafter changed or amended as provided therein or by applicable law (the “Certificate of Incorporation”). The by-laws of Merger Sub, as in effect immediately prior to the Effective Time, will be the by-laws of the Interim Surviving Corporation, until thereafter changed or amended as provided therein, by the certificate of incorporation or by applicable law (the “By-Laws”).

SECTION 1.5 Directors and Officers of the Interim Surviving Corporation. At the Effective Time, the directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Interim Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and By-Laws of the Interim Surviving Corporation. At the Effective Time, the officers of Merger Sub immediately prior to the Effective Time shall be the initial officers of the Interim Surviving Corporation, in each case until their respective successors are duly elected or appointed.

SECTION 1.6 The Step Two Merger.

(a)

Timing. On the date of the Closing, immediately following the Effective Time, the Interim Surviving Corporation shall be merged with and into the LLC in accordance with the DGCL. As a result of the Step Two Merger, the separate corporate existence of the Interim Surviving Corporation shall cease and the LLC, as a direct, wholly owned subsidiary of the Company, shall continue as the Surviving Company of the Step Two Merger.

(b)

The Step Two Merger Effective Time. On the date of the Closing, immediately following the Effective Time, the LLC shall cause the Step Two Merger to be consummated by filing a certificate of merger (the “Step Two Certificate of Merger”) and any other required documents with the Delaware Secretary of State, in such form as required by, and executed in accordance with the relevant provisions of, the DGCL. The Step Two Merger will become effective at such time as the Step Two Certificate of Merger is filed with the Delaware Secretary of State, or at such later time as the Company, the LLC and the Interim Surviving Corporation agree and specify in the Step Two Certificate of Merger (the date and time the Step Two Merger becomes effective is referred to herein as the “Step Two Merger Effective Time”).

(c)

Effect of the Step Two Merger. From and after the Step Two Merger Effective Time, the effect of the Step Two Merger shall be as provided in this Agreement, the Step Two Certificate of Merger and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Step Two Merger Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers and franchises of the LLC and the Interim Surviving Corporation shall vest in the Surviving Company, and all debts, liabilities and duties of the LLC and the Interim Surviving Corporation shall become the debts, liabilities and duties of the Surviving Company.

(d)

Certificate of Formation; Operating Agreement. The certificate of formation of the LLC, as in effect immediately prior to the Step Two Merger Effective Time, will be the certificate of formation of the Surviving Company; provided, however, that Article I of such certificate of formation shall be amended as of the Step Two Merger Effective Time to read as follows: “The name of the limited liability company is: AlphaSmart, LLC” until thereafter changed or amended as provided therein or by applicable law (the “Certificate of Formation”). The operating agreement of the LLC, as in effect immediately prior to the Step Two Merger Effective Time, will be the operating agreement of the Surviving Company, until thereafter changed or amended as provided therein, by the Certificate of Formation or by applicable law (the “Operating Agreement”).

(e)

Manager and Officers. At the Step Two Merger Effective Time, the manager of the LLC immediately prior to the Effective Time shall be the initial manager of the Surviving Company, to hold its position in accordance with the Certificate of Formation and the Operating Agreement of the Surviving Company.

(f)

Treatment of Capital Stock In Step Two Merger. Subject to the provisions of this Agreement, at the Step Two Merger Effective Time, automatically by virtue of the Step Two Merger and without any action on the part of any shareholder: (i) each membership interest of the LLC outstanding immediately prior to the Step Two Merger shall be unchanged and shall remain issued and outstanding; and (ii) each share of Interim Surviving Corporation common stock issued and outstanding prior to the Step Two Merger Effective Time shall be cancelled without consideration and shall cease to be an issued and outstanding share of Interim Surviving Corporation common stock.

SECTION 1.7 Conversion of Securities; Dissenting Shares. The manner and basis of converting the shares of Seller Common Stock (as defined in Section 1.7(a), below) upon consummation of the Step One Merger shall be as set forth in this Section 1.7. At the Effective Time, by virtue of the Step One Merger and without any action on the part of the Company, Merger Sub, Seller or any holder of Seller Common Stock:

(a)

Subject to the other provisions of this Section 1.7, each share of common stock, par value $.0001 per share, of Seller (the “Seller Common Stock”) issued and outstanding immediately prior to the Effective Time (excluding any treasury shares, shares held by the Company, any Company Subsidiary or Merger Sub and Dissenting Shares) shall be converted into the right to receive the Merger Consideration. The “Merger Consideration” shall mean either (i) cash in the amount of $3.75 (the “Price Per Share”), without interest (the “Cash Consideration”), (ii) the number of shares of common stock, par value $.01 per share, of the Company (“Company Common Stock”), rounded to the nearest four decimals (the “Exchange Rate”), equal to the Cash Consideration divided by the Average Price (the “Stock Consideration”), or (iii) a combination of Cash Consideration and Stock Consideration in accordance with subsection (c) of this Section 1.7. The “Average Price” means the volume weighted average price per share of Company Common Stock (“VWAP”) for the 10 consecutive trading days in which such shares are traded on the National Association of Securities Dealers Automated Quotations (“NASDAQ”) National Market System ending on the third trading day prior to, but not including, the Seller Stockholders’ Meeting. The Average Price shall be calculated to the nearest one-hundredth of one cent. For this purpose, the VWAP is calculated using the AQR function for Company Common Stock on Bloomberg Financial LP.

(b) The number of shares of Seller Common Stock to be converted into the right to receive Stock Consideration shall not exceed 45% of the number of shares of Seller Common Stock outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant to Section 1.7(i)) (the “Stock Election Number”), subject to Section 1.7(h)(ii). The number of shares of Seller Common Stock to be converted into the right to receive Cash Consideration shall be not less than 55% of the number of shares of Seller Common Stock outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant to Section 1.7(i)) (the “Cash Election Number”), subject to Section 1.7(h)(ii).

(c) Subject to the proration and election procedures set forth in this Section 1.7, each holder of record of shares of Seller Common Stock (excluding any treasury shares, shares held by the Company, any Company Subsidiary or Merger Sub and Dissenting Shares) shall be entitled to elect to receive (A) Cash Consideration for all such shares (a “Cash Election”), (B) Stock Consideration for all of such shares (a “Stock Election”) or (C) Cash Consideration for 55% of such shares and Stock Consideration for 45% of such shares (a “Combination Election”). All such elections shall be made on a form designed for that purpose prepared by the Company and reasonably acceptable to Seller (a “Form of Election”). Holders of record of shares of Seller Common Stock who hold such shares as nominees, trustees or in other representative capacities (a “Representative”) may submit multiple Forms of Election, provided that such Representative certifies that each such Form of Election covers all the shares of Seller Common Stock held by each such Representative for a particular beneficial owner.

(d) The Company and Seller shall mail the Form of Election to all persons who are holders of Seller Common Stock on the record date for the Seller Stockholders’ Meeting, together with the Proxy Statement/Prospectus (as defined in Section 2.11, below), and thereafter the Company and Seller shall each use its reasonable efforts to make the Form of Election available to all persons who become holders of Seller Common Stock subsequent to such day and no later than the close of business on the last business day prior to the date of the Seller Stockholders’ Meeting (the “Election Deadline”). A Form of Election must be received by the Exchange Agent in the manner described below no later than by the Election Deadline in order to be effective. All elections will be irrevocable after 5:00 p.m. local time in the city in which the principal office of the Exchange Agent is located, on the date of the Election Deadline.

(e) Prior to the Effective Time, the Company shall designate a bank or trust company reasonably acceptable to Seller to act as exchange agent hereunder (the “Exchange Agent”) for the purpose of exchanging Seller Certificates and Seller Book-Entry Shares hereunder. Elections shall be made by holders of Seller Common Stock by mailing or otherwise delivering to the Exchange Agent, in a manner acceptable to the Company, a Form of Election. To be effective, a Form of Election must be properly completed, signed and submitted to the Exchange Agent and accompanied by the certificates representing the shares of Seller Common Stock as to which the election is being made (or by an appropriate guarantee of delivery of such certificates as set forth in such Form of Election from a member of any registered national securities exchange or of the National Association of Securities Dealers, Inc. or a commercial bank or trust company having an office or correspondent in the United States, provided such certificates are in fact delivered by the time set forth in such guarantee of delivery), or in the case of Seller Book Entry Shares, any additional documentation specified in the procedures set forth in the Form of Election. The Company will have the discretion, which it may delegate in whole or in part to the Exchange Agent, to determine whether Forms of Election have been properly completed, signed and submitted and to disregard immaterial defects in Forms of Election. The decision of the Company (or the Exchange Agent) in such matters shall be conclusive and binding. Neither the Company nor the Exchange Agent will be under any obligation to notify any person of any defect in a Form of Election.

(f) A holder of Seller Common Stock who does not submit a Form of Election which is received by the Exchange Agent prior to the Election Deadline shall be deemed to have made a Stock Election. If the Company or the Exchange Agent shall determine that any purported Cash Election or Stock Election was not properly made, such purported Cash Election or Stock Election shall be deemed to be of no force and effect and the holder of shares of Seller Common Stock making such purported Cash Election or Stock Election shall for purposes hereof be deemed to have made a Stock Election.

(g) All shares of Seller Common Stock which are subject to Cash Elections are referred to herein as “Cash Election Shares.” All shares of Seller Common Stock which are subject to Stock Elections are referred to herein as “Stock Election Shares.” Subject to Section 1.7(h)(ii), if, after the results of the Forms of Election are calculated, the number of shares of Seller Common Stock to be converted into shares of Company Common Stock exceeds the Stock Election Number, all holders of Stock Election Shares shall, on a pro rata basis, have a portion of such holder’s Stock Election Shares redesignated as Cash Election Shares. The number of Stock Election Shares redesignated for each such holder shall equal such holder’s number of Stock Election Shares multiplied by the Cash Proration Factor. “Cash Proration Factor” shall be equal to one (1) minus a fraction, the numerator of which is the difference of (x) the Stock Election Number and (y) 45% of the number of shares subject to a Combination Election and the denominator of which is the number of Stock Election Shares. Holders who make Cash Elections or Combination Elections will not be subject to the redesignation procedures described in this Section 1.7(g). The Company or the Exchange Agent shall make all computations contemplated by this Section 1.7 and all such computations shall be conclusive and binding on the holders of Seller Common Stock, absent manifest error.

(h) (i) After the redesignation procedure set forth in Section 1.7(g) is completed, all Cash Election Shares and 55% of the shares of Seller Common Stock which are subject to Combination Elections shall be converted into the right to receive the Cash Consideration and all Stock Election Shares and 45% of the shares of Seller Common Stock which are subject to Combination Elections shall be converted into the right to receive the Stock Consideration. Such certificates previously evidencing shares of Seller Common Stock shall be exchanged for (A) certificates evidencing the Stock Consideration, or (B) the Cash Consideration, multiplied in each case by the number of shares previously evidenced by the canceled certificate, upon the surrender of such certificates in accordance with the provisions of Section 1.8, without interest. Notwithstanding the foregoing, however, no fractional shares of Company Common Stock shall be issued, and, in lieu thereof, a cash payment shall be made pursuant to Section 1.8(e).

(ii)

If either the tax opinion referred to in Section 7.2(g) or the tax opinion referred to in Section 7.3(d) cannot be rendered because the counsel charged with providing such opinion reasonably determines that the Mergers taken together may not satisfy the continuity of interest requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code (the “Continuity of Interest Test”), then, notwithstanding anything to the contrary in this Agreement, the Company shall reduce the Cash Election Number and correspondingly increase the Stock Election Number to the minimum extent necessary to enable the relevant tax opinions to be rendered. Solely for purposes of determining whether the Continuity of Interest Test has been satisfied, the value of a share of Company Common Stock shall be the average of the high and low trading price of a share of Company Common Stock as reported on the NASDAQ National Market System on the last trading day prior to the date of the Closing. Using the Average Price, the Exchange Agent (after consultation with the Company and the counsels referenced in Section 7.2(g) and Section 7.3(d)) shall determine the number of Cash Election Shares which must be redesignated as Stock Election Shares in order to achieve the Cash Election Number, as modified by this Section 1.7(h)(ii). All holders of Cash Election Shares shall, on a pro rata basis, have such number of their Cash Election Shares redesignated as Stock Election Shares so that the Cash Election Number and Stock Election Number, as modified by this Section 1.7(h)(ii), are achieved, assuming Dissenting Shares will be paid in cash at a rate of $3.75 per share. If, after the redesignation of Cash Election Shares as Stock Election Shares in accordance with this Section 1.7(h)(ii), either the tax opinion referred to in Section 7.2(g) or the tax opinion referred to in Section 7.3(d) cannot be rendered because the counsel charged with providing such opinion reasonably determines that the Mergers taken together may not satisfy the Continuity of Interest Test, then, on a pro rata basis, a portion of the shares subject to each Combination Election that were to be exchanged for Cash Consideration shall instead be exchanged for Stock Consideration in accordance with the methodology set forth in this section 1.7(h)(ii), so that the Cash Election Number and the Stock Election Number, as modified by this Section 1.7(h)(ii), are achieved, assuming Dissenting Shares will be paid in cash at a rate of $3.75 per share.

(i) Each share of Seller Common Stock held in the treasury of Seller and each share of Seller Common Stock owned by the Company, the Company Subsidiaries or Merger Sub immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no payment shall be made with respect thereto.

(j) All of the shares of Company Common Stock issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding after the Effective Time and shall be unaffected by the Mergers. At the Effective Time, all shares of Seller Common Stock will no longer be outstanding and will automatically be canceled and retired, and each holder of a Seller Certificate or Seller Book-Entry Shares will cease to have any rights with respect thereto, except the right to receive the Merger Consideration applicable thereto.

(k) If, after determination of the Average Price and prior to the Effective Time, the Company shall pay a dividend in, subdivide, combine into a smaller number of shares or issue by reclassification of its shares, any shares of Company Common Stock, the Exchange Rate shall be multiplied by a fraction, the numerator of which shall be the number of shares of Company Common Stock outstanding immediately after, and the denominator of which shall be the number of such shares outstanding immediately before, the occurrence of such event, and the resulting product shall from and after the date of such event be the Exchange Rate, subject to further adjustment in accordance with this sentence.

(l) At the Effective Time, by virtue of the Step One Merger and without any action on the part of the Company as the sole stockholder of Merger Sub, each issued and outstanding share of common stock, par value $.0001 per share, of Merger Sub (“Merger Sub Common Stock”) shall be converted into one share of common stock, par value $.0001 per share of the Interim Surviving Corporation.

(m) Notwithstanding anything in this Agreement to the contrary, shares of Seller Common Stock outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Mergers or consented thereto in writing and who has properly demanded appraisal for such Seller Common Stock in accordance with the requirements of Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into the right to receive the relevant Merger Consideration and the holders thereof shall be entitled to only such rights as are granted by the DGCL, unless such holder fails to perfect, withdraws or otherwise loses the right to appraisal, in which case such shares of Seller Common Stock shall be treated as if they had been converted as of the Effective Time into the right to receive the relevant Merger Consideration, as set forth in this Section 1.7, without any interest thereon. Seller shall give the Company prompt notice of any demands received by Seller for appraisal of shares of Seller Common Stock, withdrawals of such demands, and any other instruments or documents served pursuant to the DGCL and received by Seller, and Seller shall give the Company the opportunity to participate in all negotiations and proceedings with respect to such demands. Except with the prior written consent of the Company (which shall not be unreasonably withheld, delayed or conditioned), Seller shall not make any payment with respect to, or offer to settle or settle, any such demands. Each holder of Dissenting Shares who becomes entitled to payment for such Dissenting Shares under the provisions of Section 262 of the DGCL, will receive payment thereof from the Surviving Company and as of the Effective Time such shares of Seller Common Stock will no longer be outstanding and will automatically be canceled and retired and will cease to exist.

SECTION 1.8 Surrender of Certificates.

(a) Exchange Agent. As of the Effective Time, the Company shall deposit, or shall cause to be deposited, from time to time, with the Exchange Agent, for the benefit of the holders of Seller Common Stock, for exchange in accordance with this Article I, through the Exchange Agent, the Merger Consideration, together with any dividends or distributions with respect thereto, if any, to be issued pursuant to Section 1.7 in exchange for outstanding shares of Seller Common Stock (the “Exchange Fund”).

(b) Surrender Procedures. Promptly after the Effective Time, the Company shall cause to be mailed to each record holder, as of the Effective Time, of certificates representing outstanding shares of Seller Common Stock (“Seller Certificates”) or shares of Seller Common Stock represented by book-entry (“Seller Book-Entry Shares”) (other than such holders who properly made a Cash Election, Stock Election or Combination Election with respect to such Seller Certificates or Seller Book-Entry Shares in accordance with Section 1.7 and other than Dissenting Shares), a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Seller Certificates shall pass, only upon proper delivery of the Seller Certificates to the Exchange Agent or, in the case of Seller Book-Entry Shares, upon adherence to the procedures set forth in the letter of transmittal) and instructions for use in effecting the surrender of the Seller Certificates or, in the case of Seller Book-Entry Shares, the surrender of such shares for payment of the Merger Consideration therefor. After the Effective Time, upon surrender in accordance with this Section 1.8(b) or in connection with a Form of Election delivered pursuant to Section 1.7(d), to the Exchange Agent of a Seller Certificate or Seller Book-Entry Shares, together with such letter of transmittal or a Form of Election pursuant to Section 1.7(d), duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the Exchange Agent shall promptly deliver to the holder of such Seller Certificate or Seller Book-Entry Shares in exchange therefor, the Merger Consideration to be received by the holder thereof pursuant to this Agreement. The Exchange Agent shall accept such Seller Certificates or Seller Book-Entry Shares upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. After the Effective Time, there shall be no further transfer on the records of Seller or its transfer agent of shares of Seller Common Stock and, if Seller Certificates or Seller Book-Entry Shares are presented to Seller for transfer, they shall be canceled against delivery of the applicable Merger Consideration. If any Merger Consideration is to be issued in a name other than that in which the Seller Certificate surrendered for exchange is registered, it shall be a condition of such exchange that the Seller Certificate so surrendered shall be properly endorsed, with signature guaranteed, or otherwise in proper form for transfer, and that the person requesting such exchange shall pay to Seller or its transfer agent any transfer or other taxes required by reason of the issuance of the Merger Consideration in a name other than that of the registered holder of the Seller Certificate surrendered, or establish to the satisfaction of the Company that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 1.8(b), each Seller Certificate and each Seller Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable Merger Consideration as contemplated by Section 1.7.

(c) Dividends with Respect to Unexchanged Shares. No dividends or other distributions with respect to shares of Company Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Seller Certificate or Seller Book-Entry Share with respect to the shares of Company Common Stock to be received in respect thereof and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 1.8(e), in each case until the surrender of such Seller Certificate or Seller Book-Entry Share in accordance with this Article I. Subject to the effect of applicable laws (including but not limited to applicable abandoned property, escheat or other similar laws), following surrender of any such Seller Certificate or Seller Book-Entry Share, there shall be paid to the holder of such Seller Certificate or Seller Book-Entry Share, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of fractional shares of Company Common Stock to which such holder is entitled pursuant to Section 1.8(e) and any dividends or other distributions with a record date after the Effective Time theretofore paid with respect to whole shares of Company Common Stock to which such holder is entitled pursuant to this Agreement, and (ii) at the appropriate payment date, any 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 Company Common Stock.

(d) No Further Rights in the Shares. The Merger Consideration paid upon the surrender for exchange of Seller Certificates or Seller Book-Entry Shares in accordance with the terms of this Article I (including any cash paid pursuant to Section 1.8(e)) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Seller Common Stock so exchanged.

(e) No Fractional Shares. No new Seller Certificates representing fractional shares of Company Common Stock shall be issued in connection with the Mergers and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Seller after the Mergers. Instead, each holder of shares of Seller Common Stock exchanged pursuant to the Mergers who would otherwise have been entitled to receive a fraction of a share of Company Common Stock (after taking into account all shares of Seller Common Stock delivered by such holder) shall receive a cash payment (without interest rounded up to the nearest whole cent) determined by multiplying the fractional share interest to which such holder would otherwise be entitled by the closing price for a share of Company Common Stock as reported on the NASDAQ National Market System on the trading day immediately preceding the date of the Seller Stockholders’ Meeting.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the former stockholders of Seller for six (6) months after the Effective Time shall be delivered to the Company, upon demand, and any former stockholders of Seller who have not theretofore complied with this Article I shall thereafter look only to the Company and the Surviving Company to claim their Merger Consideration, without interest thereon, and subject to Section 1.8(h).

(g) No Liability. Neither the Company, the Surviving Company or the Exchange Agent shall be liable to any former holder of shares of Seller Common Stock for any such shares of Seller Common Stock (or dividends or distributions with respect thereto), Company Common Stock, or cash or other payment delivered to a public official pursuant to any abandoned property, escheat or similar laws.

(h) Withholding Rights. The Company shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any former holder of shares of Seller Common Stock such amounts as the Company is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law, and the Company shall timely pay over such withheld amounts to the appropriate taxing authority. To the extent that amounts are so withheld by the Company, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the former holder of the Shares in respect of which such deduction and withholding was made by the Company.

(i) Lost, Stolen or Destroyed Certificate. If any Seller Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Seller Certificate to be lost, stolen or destroyed and, if requested by the Surviving Company, the posting by such person of a bond, in such reasonable amount as the Surviving Company may direct, as indemnity against any claim that may be made against it with respect to such Seller Certificate, the Exchange Agent will pay, in exchange for such lost, stolen or destroyed Seller Certificate, the Merger Consideration to be paid in respect of the shares of Seller Common Stock represented by such Seller Certificate.

ARTICLE II - REPRESENTATIONS AND WARRANTIES OF SELLER

Except as set forth in the disclosure schedule delivered by Seller to the Company prior to the execution of this Agreement (the “Seller Disclosure Letter”), which shall identify exceptions by specific section references (provided that any such exception shall also be applicable to any other section of this Article II with respect to which the relevance of such exception is reasonably apparent), Seller hereby represents and warrants to the Company that:

(b) Seller and each Seller Subsidiary is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of its properties owned, leased or operated by it or the nature of its activities makes such qualification or licensing necessary, except for such failures to be so duly qualified or licensed and in good standing that would not, either individually or in the aggregate, have a Material Adverse Effect on Seller and Seller Subsidiaries, taken as a whole.

(c) A true and complete list as of the date of this Agreement of all of the Seller Subsidiaries, together with (i) Seller’s percentage ownership of each Seller Subsidiary and (ii) laws under which the Seller Subsidiary is incorporated or organized is set forth on Section 2.1(c) of the Seller Disclosure Letter.

Seller has heretofore furnished to the Company a complete and correct copy of the certificate of incorporation and the by-laws, as amended or restated, of Seller (the “Seller Organizational Documents”) and the certificate of incorporation and the by-laws, or other organizational documents, as the case may be, of each Seller Subsidiary (the “Subsidiary Organizational Documents”). The Seller Organizational Documents and the Subsidiary Organizational Documents are in full force and effect. Neither Seller nor any Seller Subsidiary is in violation of any of the provisions of the Seller Organizational Documents or the Subsidiary Organizational Documents, respectively.

SECTION 2.3 Capitalization. The authorized capital stock of Seller consists of 30,000,000 shares of Seller Common Stock and 5,000,000 shares of preferred stock (“Seller Preferred Stock”). As of January 4, 2005, (i) 14,899,278 shares of Seller Common Stock were issued and outstanding, all of which were duly authorized, validly issued, fully paid and non-assessable, and not issued in violation of any preemptive right of any Seller stockholder, and no shares of Seller Preferred Stock were issued and outstanding, (ii) no shares of Seller Common Stock and no shares of Seller Preferred Stock were held in the treasury of Seller, and (iii) 915,087 shares of Seller Common Stock were subject to outstanding stock options issued pursuant to Seller’s Option Plans (as defined in Section 5.5, below) as of January 14, 2005. Section 2.3 of the Seller Disclosure Letter sets forth, with respect to each Option (as defined in Section 2.25, below), except rights to purchase Seller Common Stock under the Seller’s 2003 Employee Stock Purchase Plan (the “ESPP”): (i) the name of the holder of such Option; (ii) the total number of shares of Seller Common Stock that are subject to such Option and the number of shares of Seller Common Stock with respect to which such Option is exercisable (including by virtue of the transactions contemplated by this Agreement); (iii) the date on which such Option was granted and the term of such Option; (iv) the vesting schedule for such Option (or if such Option is immediately exercisable by virtue of the transactions contemplated by this Agreement, a notation to that effect set forth in Section 2.3 of the Seller Disclosure Letter or a comparable notation that is applicable to all the Options listed in Section 2.3 of the Seller Disclosure Letter set forth elsewhere in Section 2.3 of the Seller Disclosure Letter); (v) the exercise price per share of Seller Common Stock purchasable under such Option; and (vi) whether such Option has been designated an “incentive stock option” as defined in Section 422 of the Code. Seller has delivered or made available to the Company accurate and complete copies of Seller’s Option Plans and each form of option agreement evidencing any Option. All of the issued and outstanding shares of Seller Common Stock and Options have been issued in all material respects in compliance with all applicable federal and state securities laws or in accordance with exemptions therefrom. There are no outstanding options, warrants or other rights, agreements, arrangements or commitments of any character to which Seller or any Seller Subsidiary is a party, including, without limitation, voting agreements or arrangements (except as contemplated by this Agreement or the Stockholders Voting Agreement), relating to the issued or unissued capital stock or other equity interests of Seller or any Seller Subsidiary or obligating Seller or any Seller Subsidiary to issue or sell any shares of capital stock or other equity interests of, or other equity interests in, Seller or any Seller Subsidiary. There are no obligations, contingent or otherwise, of Seller or any Seller Subsidiary to repurchase, redeem or otherwise acquire any shares of Seller Common Stock or the capital stock or other equity interests of any Seller Subsidiary or to provide funds to or make any investment (in the form of a loan, capital contribution or otherwise) in any Seller Subsidiary or any other entity, except for loan commitments and other funding obligations entered into in the ordinary course of business and repurchase rights arising upon an individual’s termination of service with the Seller or any Seller Subsidiary. Each of the outstanding shares of capital stock or other equity interests of each Seller Subsidiary are duly authorized, validly issued, fully paid and non-assessable, and were not issued in violation of any preemptive rights of any Seller Subsidiary shareholder or other equity holder, and such shares or other equity interests owned by Seller or another Seller Subsidiary are owned free and clear of all security interests, liens, claims, pledges, agreements, limitations of Seller’s voting rights, charges or other encumbrances of any nature whatsoever. Except as contemplated by this Agreement, there are no registration rights, and there is no voting trust, proxy, rights agreement, “poison pill” anti-takeover plan or other agreement or understanding to which Seller is a party or by which it is bound with respect to any equity security of any class of Seller or with respect to any equity security, partnership interest or similar ownership interest of any class of any of the Seller Subsidiaries.

SECTION 2.4 Authority. Seller has the requisite corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby (other than, with respect to the Mergers, the approval and adoption of this Agreement by Seller’s stockholders in accordance with the DGCL and the Seller Organizational Documents). The execution and delivery of this Agreement by Seller and the consummation by Seller of the transactions contemplated hereby have been duly and validly authorized by all necessary corporate action, including, without limitation, Seller’s Board of Directors, and the Seller’s Board of Directors has directed that this Agreement and the consummation by Seller of the transactions contemplated hereby shall be submitted to a vote of Seller’s stockholders, and no other corporate proceedings on the part of Seller are necessary to authorize this Agreement or to consummate the transactions so contemplated hereby (other than, with respect to the Mergers, the approval and adoption of this Agreement by Seller’s stockholders in accordance with the DGCL and the Seller Organizational Documents). This Agreement has been duly executed and delivered by, and constitutes a valid and binding obligation of Seller and assuming due authorization, execution and delivery by the Company, Merger Sub and the LLC, enforceable against Seller in accordance with its terms, except as enforcement may be limited by general principles of equity whether applied in a court of law or a court of equity and by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally.

SECTION 2.5 No Conflict; Required Filings and Consents

(b) The execution and delivery of this Agreement by Seller do not, and the performance of this Agreement by Seller shall not, require any consent, approval, authorization or permit of, or filing with or notification to, any governmental or regulatory authority, domestic or foreign, except (i) for applicable requirements, if any, of the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended (the “Exchange Act”), state securities or blue sky laws (“Blue Sky Laws”), the filing and recordation of appropriate merger or other documents as required by the DGCL, and prior notification filings with the Department of Justice under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Act (the “HSR Act”) and (ii) where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not prevent or delay consummation of the Mergers or otherwise prevent Seller from performing its obligations under this Agreement, and would not have a Material Adverse Effect on Seller and Seller Subsidiaries, taken as a whole.

SECTION 2.6 Compliance; Permits. Neither Seller nor any Seller Subsidiary is in conflict with, or in default or violation of, (i) any Law applicable to Seller or any Seller Subsidiary or by which its or any of their respective properties is bound or affected, or (ii) any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which Seller or any Seller Subsidiary is a party or by which Seller or any Seller Subsidiary or its or any of their respective properties is bound or affected, except for any such conflicts, defaults or violations which would not, individually or in the aggregate, have a Material Adverse Effect on Seller and Seller Subsidiaries, taken as a whole.

SECTION 2.7 Securities Reports; Financial Statements.

(a) Seller and each Seller Subsidiary have filed all forms, reports and documents required to be filed with the SEC since February 6, 2004, and as of the date of this Agreement have delivered or made available to the Company (including pursuant to the SEC’s website), in the form filed with the SEC, (i) all Reports on Form 10-Q filed by Seller since February 6, 2004, (ii) all Reports on Form 8-K filed by Seller with the SEC since February 6, 2004, (iii) all other reports or registration statements filed by Seller with the SEC since February 6, 2004, (iv) the final registration statement on Form S-1 and the final prospectus filed with the SEC in connection with Seller’s initial public offering and (v) all amendments and supplements to all such reports and registration statements filed by Seller with the SEC since February 6, 2004 (collectively, the “Seller SEC Reports”). The Seller SEC Reports, including all Seller SEC Reports filed after the date of this Agreement which shall include Seller’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004 and all proxy statements relating to Seller’s meetings of stockholders (whether annual or special) held after the date hereof, (i) were or will be prepared in accordance in all material respects with the requirements of applicable Law and (ii) did not at the time they were filed, or will not at the time they are filed, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(b) Each of the consolidated financial statements (including, in each case, any related notes thereto) contained in the Seller SEC Reports, including any Seller SEC Reports filed since the date of this Agreement and prior to or on the Effective Time, have been or will be prepared in accordance with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or required by reason of a concurrent change to GAAP) and each fairly presents in all material respects the consolidated financial position of Seller and Seller Subsidiaries as of the respective dates thereof and the consolidated results of its operations and cash flows and changes in financial position for the periods indicated, except that any unaudited interim financial statements were or are subject to normal and recurring year-end adjustments, which were not or are not expected to be material in amount, either individually or in the aggregate. Seller has not had any dispute with any of its auditors regarding accounting matters or policies during any of its past three full fiscal years or during the current fiscal year-to-date requiring disclosure pursuant to Item 304 of Regulation S-K promulgated by the SEC. To Seller’s knowledge, Seller’s auditors will deliver to Seller an unqualified audit opinion with respect to Seller’s financial statements as of and for the year ended December 31, 2004.

(c) Seller, and to the knowledge of Seller, each of its officers and directors are in compliance with and have complied in all material respects with (A) the applicable provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 (“▇▇▇▇▇▇▇▇-▇▇▇▇▇”) and any related rules and regulations promulgated by the SEC thereunder and (B) the applicable listing and corporate governance rules and regulations of NASDAQ. With respect to each Report on Form 10-Q and each amendment of any such report filed by Seller with the SEC since February 6, 2004, the Chief Executive Officer and Chief Financial Officer of Seller have made all certifications required by ▇▇▇▇▇▇▇▇-▇▇▇▇▇ and the rules and regulations promulgated thereunder at the time of such filing, and to Seller’s knowledge, the statements contained in each such certification were true and correct when made. Further, Seller has established and maintains “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) that are reasonably designed to ensure that material information (both financial and non-financial) relating to Seller and the subsidiaries required to be disclosed by Seller in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to Seller’s principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the principal executive officer and the principal financial officer of Seller required by Section 302 of ▇▇▇▇▇▇▇▇-▇▇▇▇▇ with respect to such reports. For purposes of this Agreement, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in ▇▇▇▇▇▇▇▇-▇▇▇▇▇. Based on the most recent evaluation by Seller’s Chief Executive Officer and Chief Financial Officer, there are no “significant deficiencies” in the design or operation of Seller’s internal controls and procedures which could adversely affect Seller’ ability to record, process, summarize and report financial data or any “material weaknesses” in Seller’s internal controls. For purposes of this Agreement, a “significant deficiency” in controls means a control deficiency that adversely affects an entity’s ability to initiate, authorize, record, process, or report external financial data reliably in accordance with GAAP. A “significant deficiency” may be a single deficiency or a combination of deficiencies that results in more than a remote likelihood that a misstatement of the annual or interim financial statements that is more than inconsequential will not be prevented or detected. For purposes of this Agreement, a “material weakness” in controls means a significant deficiency, or a combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

(d) Except (i) for those liabilities that are fully reflected or reserved against on the consolidated balance sheet as of September 30, 2004, (ii) for liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2004, and (iii) as set forth in Section 2.7(d) of the Seller Disclosure Letter, neither Seller nor any Seller Subsidiary has incurred any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise due or to become due), required to be disclosed on a balance sheet prepared in accordance with GAAP, that, either alone or when combined with all similar liabilities, has had, or would reasonably be expected to have, a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole.

(e) Seller has not been notified by its independent registered public accounting firm or by the staff of the SEC that such accounting firm or the staff of the SEC, as the case may be, are of the view that any financial statement included in any registration statement filed by Seller under the Securities Act or any periodic or current report filed by Seller under the Exchange Act should be restated, or that Seller should modify its accounting in future periods in a manner that would have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole.

(f) Since January 1, 2004, neither Seller nor the Seller Subsidiaries nor, to Seller’s knowledge, any director, officer, employee, auditor, accountant or representative of Seller or the Seller Subsidiaries, has received or otherwise had or obtained knowledge of any complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods of Seller or the Seller Subsidiaries or their respective internal accounting controls, including any complaint, allegation, assertion or claim that Seller or the Seller Subsidiaries has engaged in questionable accounting or auditing practices. To Seller’s knowledge, no attorney representing Seller or the Seller Subsidiaries, whether or not employed by Seller or the Seller Subsidiaries, has reported evidence of a material violation of securities laws, breach of fiduciary duty or similar violation by Seller or any of its officers, directors, employees or agents to the Board of Directors of Seller or any committee thereof or to any director or officer of Seller.

Neither Seller nor any Seller Subsidiary is a party to any joint marketing or other affinity marketing program with a third party.

SECTION 2.10 Employee Benefit Plans

(a) Current Plans. Section 2.10(a) of the Seller Disclosure Letter lists all employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), and all bonus, stock option, stock purchase, restricted stock, incentive, deferred compensation, retiree medical or life insurance, supplemental retirement, severance or other benefit plans, programs or arrangements, and all material employment, termination, severance or other employment contracts or employment agreements, with respect to which Seller or any Seller Subsidiary has any obligation (each, a “Plan,” and collectively, the “Plans”). Seller has furnished or made available to the Company a complete and accurate copy of each Plan (or a description of the Plans, if the Plans are not in writing) and a complete and accurate copy of each material document prepared in connection with each such Plan, including, without limitation, and where applicable, a copy of (i) each trust or other funding arrangement, (ii) each summary plan description and summary of material modifications, (iii) the three most recently filed IRS Forms 5500 and related schedules, (iv) the most recently issued IRS determination letter for each such Plan and the materials submitted to obtain that letter, and (v) the three most recently prepared actuarial and financial statements with respect to each such Plan.

No Title IV Plan is a “multiemployer pension plan” as defined in Section 3(37) of ERISA. None of the Plans obligates Seller or any of the Seller Subsidiaries to pay material separation, severance, termination or similar-type benefits solely as a result of any transaction contemplated by this Agreement or as a result of a “change in control,” within the meaning of such term under Section 280G of the Code. Except as required by COBRA or a similar statute, none of the Plans provides for or promises retiree medical, disability or life insurance benefits to any current or former employee, officer or director of Seller or any of the Seller Subsidiaries. Each of the Plans is subject only to the laws of the United States or a political subdivision thereof.

(c) Compliance with Applicable Law. Each Plan has been operated in all respects in accordance with the requirements of all applicable Law and all persons who participate in the operation of such Plans and all Plan “fiduciaries” (within the meaning of Section 3(21) of ERISA) have acted in accordance with the provisions of all applicable Law, except where such violations of applicable Law would not, individually or in the aggregate, have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole. Seller and the Seller Subsidiaries have performed all obligations required to be performed by any of them under, are not in any respect in default under or in violation of, and Seller and the Seller Subsidiaries have no knowledge of any default or violation by any party to, any Plan, except where such failures, defaults or violations would not, individually or in the aggregate, have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole. No legal action, suit or claim is pending or, to the knowledge of Seller or the Seller Subsidiaries, threatened with respect to any Plan (other than claims for benefits in the ordinary course) and to the knowledge of Seller or the Seller Subsidiaries, no fact or event exists that could give rise to any such action, suit or claim. Neither Seller nor any Seller Subsidiary has incurred any material liability under Section 302 of ERISA or Section 412 of the Code that has not been satisfied in full and no condition exists that presents a material risk of incurring any such liability.

(d) Qualification of Certain Plans. Each Plan that is intended to be qualified under Section 401(a) of the Code or Section 401(k) of the Code (including each trust established in connection with such a Plan that is intended to be exempt from Federal income taxation under Section 501(a) of the Code) has received a favorable determination letter from the IRS (as defined herein) that it is so qualified, and Seller is not aware of any fact or event that could adversely affect the qualified status of any such Plan. No trust maintained or contributed to by Seller or any of the Seller Subsidiaries is intended to be qualified as a voluntary employees’ beneficiary association or is intended to be exempt from federal income taxation under Section 501(c)(9) of the Code.

(e) Absence of Certain Liabilities and Events. Except for matters disclosed in Section 2.10(e) of the Seller Disclosure Letter, there has been no non-exempt prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code) with respect to any Plan. Seller and each of the Seller Subsidiaries has not incurred any liability for any excise tax arising under Sections 4971 through 4980G of the Code that would individually or in the aggregate have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole, and, to the knowledge of Seller or the Seller Subsidiaries, no fact or event exists that could give rise to any such liability.

(f) Plan Contributions. All contributions, premiums or payments required to be made with respect to any Plan have been made or properly accrued on or before their due dates.

(g) Employment Contracts. Neither Seller nor any Seller Subsidiary is a party to employment, severance, consulting or other similar contracts with any employees, consultants, officers or directors of Seller or any of the Seller Subsidiaries. Neither Seller nor any Seller Subsidiary is a party to any collective bargaining agreements.

(h) Effect of Agreement. The consummation of the transactions contemplated by this Agreement will not, either alone or in conjunction with another event, entitle any current or former employee of Seller or any Seller Subsidiary to severance pay, unemployment compensation or any other payment, including payments constituting “excess parachute payments” within the meaning of Section 280G of the Code, or accelerate the time of payment or vesting or increase the compensation due any such employee or former employee.

SECTION 2.11 Registration Statement; Proxy Statement/Prospectus. The information supplied by Seller for inclusion in the Registration Statement (as defined in Section 3.10, below) shall not at the time the Registration Statement is declared effective contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The information supplied by Seller for inclusion in the proxy statement/prospectus to be sent to the stockholders of Seller in connection with the meeting of Seller’s stockholders to consider the Mergers (the “Seller Stockholders’ Meeting”) (such proxy statement/prospectus as amended or supplemented is referred to herein as the “Proxy Statement/Prospectus”) shall not at the date the Proxy Statement/Prospectus (or any amendment thereof or supplement thereto) is first mailed to stockholders and at the time of the Seller Stockholders’ Meeting, be false or misleading with respect to any material fact required to be stated therein, or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they are made, not misleading. If at any time prior to the Effective Time any event relating to Seller or any of its affiliates, officers or directors should be discovered by Seller which should be set forth in an amendment to the Registration Statement or a supplement to the Proxy Statement/Prospectus, Seller shall promptly inform the Company. The Proxy Statement/Prospectus shall comply in all material respects as to form with the requirements of the Securities Act, the Exchange Act and the rules and regulations thereunder. Notwithstanding the foregoing, Seller makes no representation or warranty with respect to any information about, or supplied or omitted by, a person, other than Seller, the Seller Subsidiaries or any of its officers, directors and employees, which is contained in any of the foregoing documents.

SECTION 2.12 Title to Property. Seller and each of the Seller Subsidiaries has good and valid title to all of their respective properties and assets, real and personal, free and clear of all mortgage liens, and free and clear of all other liens, charges and encumbrances except liens for taxes not yet due and payable, pledges to secure deposits and such minor imperfections of title, if any, as do not materially interfere with the present use of the property affected thereby or which, individually or in the aggregate, would not have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole; and all leases pursuant to which Seller or any of the Seller Subsidiaries lease from others material amounts of real or personal property are in good standing, valid and effective in accordance with their respective terms, and there is not, under any of such leases, any existing material default or event of default (or event which with notice or lapse of time, or both, would constitute a material default and in respect of which Seller or such Seller Subsidiary has not taken adequate steps to prevent such a default from occurring). Substantially all of Seller’s and each of the Seller Subsidiaries’ buildings and equipment in regular use have been reasonably maintained and are in serviceable condition, reasonable wear and tear excepted. Section 2.12 of the Seller Disclosure Letter sets forth the address of all real property owned by Seller or any Seller Subsidiary as of the date hereof and the address of all real property in which the Seller or any Seller Subsidiary holds a leasehold or subleasehold estate (including a description of the lease or sublease applicable thereto).

SECTION 2.13 Intellectual Property.

(a) Section 2.13(a) of the Seller Disclosure Letter sets forth a complete and correct list of each of the following which is owned by Seller or a Seller Subsidiary: (i) each registered Seller ▇▇▇▇; (ii) each Seller Patent; and (iii) each registered Seller Copyright. Seller or a Seller Subsidiary: (i) owns all right, title and interest in and to the Intellectual Property Rights, free and clear of all encumbrances; or (ii) is licensed to use, or otherwise possesses legally valid and enforceable rights to use, the Intellectual Property Rights that it does not so own. Seller and the Seller Subsidiaries have made all necessary filings, recordations and payments to protect and maintain their interests in the Intellectual Property Rights owned by or licensed to Seller except where the failure to make such filings, recordations or payments would not have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole. To Seller’s knowledge (which knowledge qualifier shall apply to patents only), none of the products, services or technology used, sold, offered for sale or licensed or proposed for use, sale, offer for sale or license by Seller or any of the Seller Subsidiaries infringes any intellectual property rights of any person.

To Seller’s knowledge, no Seller Secret Information has been misused or divulged without being subject to a nondisclosure agreement, or misappropriated for the benefit of any person (other than Seller or any of the Seller Subsidiaries) or otherwise misappropriated in a manner which would have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole.

(f) No Intellectual Property Right is subject to any outstanding order, proceeding (other than pending proceedings pertaining to applications for patent or trademark or copyright registration) or stipulation that restricts in any manner the licensing thereof by Seller or any of the Seller Subsidiaries.

(g) To Seller’s knowledge, none of its employees engaged in the development of software or in performing sales and marketing functions on behalf of Seller is obligated under any contract with any third party which would materially conflict with such employee’s rights to develop software or engage in such sales and marketing functions on behalf of Seller.

(h) All employees, contractors, agents and consultants of Seller or any of the Seller Subsidiaries who are or were involved in the creation of Intellectual Property Rights owned by Seller have executed an assignment of inventions agreement to vest in Seller or any of the Seller Subsidiaries, as appropriate, exclusive ownership of such Intellectual Property Rights, except where the failure to have executed such an agreement will not have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole. All employees, contractors, agents and consultants of Seller or the Seller Subsidiaries who have or have had access to Seller Secret Information owned by Seller have executed nondisclosure agreements to protect the confidentiality of such Seller Secret Information, except where the failure to have executed such an agreement will not have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken as a whole.

(i) Without limiting the generality of the foregoing, all the software that Seller or any of the Seller Subsidiaries licenses or otherwise makes available to customers, and all Intellectual Property Rights therein, were: (i) developed by employees of Seller or of a Seller Subsidiary within the scope of their employment and subject to their obligation to assign inventions and patents therein; or (ii) developed by independent contractors or consultants who assigned, in writing, all of their right, title and interest in and to that software to Seller; or (iii) otherwise acquired or licensed by Seller from a third party by an agreement or contract that is disclosed in Section 2.13(i) of the Seller Disclosure Letter.

(j) All material contracts, licenses and agreements relating to the Intellectual Property Rights are in full force and effect. The consummation of the transactions contemplated by this Agreement will neither violate nor result in the breach, modification, cancellation, termination, or suspension of such contracts, licenses and agreements. Seller and the Seller Subsidiaries are in material compliance with, and have not materially breached any term of any of such contracts, licenses and agreements and, to the knowledge of Seller and the Seller Subsidiaries, all other parties to such contracts, licenses and agreements are in compliance in all material respects with, and have not materially breached any term of, such contracts, licenses and agreements. Following the Effective Time, the Surviving Company will be permitted to exercise all of Seller’s rights under such contracts, licenses and agreements to the same extent Seller would have been able to had the transactions contemplated by this Agreement not occurred and without the payment of any additional amounts or consideration other than ongoing fees, royalties or payments which Seller would otherwise be required to pay.

(a) Seller shall immediately cease and cause to be terminated any existing discussions or negotiations relating to a Competing Proposal (as defined below), other than with respect to the Mergers, with any parties conducted heretofore. Seller will not, directly or indirectly, and will not authorize or knowingly permit any of its directors, officers, employees, accountants, consultants, legal counsel, agents, investment bankers and other advisors (collectively, “Advisors”) of Seller or any of the Seller Subsidiaries to, directly or indirectly, initiate, solicit or encourage (including by way of furnishing information or assistance), or knowingly take any other action or facilitate, any inquiries or the making of any proposal that constitutes, or would reasonably be expected to lead to, any Competing Proposal, or enter into or maintain discussions or negotiate with any person in furtherance of or relating to such inquiries or to obtain a Competing Proposal, or agree to or endorse any Competing Proposal or authorize or permit any Advisor of Seller or any Seller Subsidiary to take any such action, and Seller shall promptly and in any event within one (1) business day of Seller’s knowledge notify the Company if any such inquiries or proposals are made regarding a Competing Proposal, and Seller shall provide the Company, as promptly as practicable, oral and written notice setting forth the terms of any material amendments to such proposals; provided, however, that prior to such time as the stockholders of Seller shall have adopted and approved this Agreement in accordance with the DGCL, nothing contained in this Agreement shall prohibit the Board of Directors of Seller from, in connection with a Competing Proposal that the Board of Directors of Seller in good faith, after consultation with its outside counsel and financial advisor, concludes is likely to result in, or constitutes, a Superior Competing Transaction (as defined below), furnishing information to, or entering into discussions or negotiations with, any person that makes an unsolicited bona fide proposal to acquire Seller pursuant to a merger, consolidation, share exchange, business combination or other similar transaction, if, and only to the extent that, (A) the Board of Directors of Seller, after consultation with its outside counsel, determines in good faith that failure to take such action would be reasonably likely to constitute failure of the Board of Directors of Seller to comply with its fiduciary duties to stockholders imposed by Delaware law, (B) prior to furnishing such information to, or entering into discussions or negotiations with, such person, Seller provides written notice to the Company to the effect that is furnishing information to, or entering into discussions or negotiations with, such person, (C) prior to furnishing such information to such person, Seller receives from such person an executed confidentiality agreement, and (D) Seller keeps the Company informed, on a current basis, of the status and details of any such discussions or negotiations. Nothing contained in this Agreement shall prohibit Seller or the Board of Directors of Seller from complying with Rule 14e-2 or Rule 14d-9 promulgated under the Exchange Act.

(b) For purposes of this Agreement, “Competing Proposal” shall mean any of the following involving Seller or any Seller Subsidiary: any inquiry, proposal or offer from any person relating to any direct or indirect acquisition or purchase of a business that constitutes 15% or more of the net revenues, net income or the assets of Seller and the Seller Subsidiaries taken as a whole, or 15% or more of any class of equity securities of Seller or any of the Seller Subsidiaries, any tender offer or exchange offer that if consummated would result in any person beneficially owning 15% or more any class of equity securities of Seller or any of the Seller Subsidiaries, or any merger, consolidation, business combination, recapitalization, or similar transaction involving Seller or any of the Seller Subsidiaries, other than the transactions contemplated by this Agreement.

(c) For purposes of this Agreement “Superior Competing Transaction” shall mean any of the following involving Seller or any Seller Subsidiary: any proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or securities, more than 50% of the combined voting power of the shares of Seller Common Stock then outstanding or all or substantially all of the assets of Seller, and otherwise on terms which the Board of Directors of Seller determines in its good faith judgment (after consultation with its outside counsel and financial advisor) to be more favorable to its stockholders than the Mergers and for which financing, to the extent required, is then committed or which if not committed is, in the good faith judgment of its Board of Directors, reasonably capable of being obtained by such third party.

SECTION 4.4 Affiliates; Tax Treatment. Within thirty (30) days after the date of this Agreement (a) Seller shall deliver to the Company a letter identifying all persons who are then “affiliates” of Seller, including, without limitation, all directors and executive officers of Seller, for purposes of Rule 145 promulgated under the Securities Act (each a “Seller Affiliate”) and (b) Seller shall advise the persons identified in such letter of the resale restrictions imposed by applicable securities laws. Seller shall use its commercially reasonable efforts to obtain from each person identified in such letter a written agreement, substantially in the form attached hereto as Exhibit 4.4.

ARTICLE VI - ADDITIONAL AGREEMENTS

SECTION 6.1 Registration Statement; Proxy Statement/Prospectus. As promptly as practicable after the execution of this Agreement, Seller and the Company shall prepare and file with the SEC the Proxy Statement/Prospectus and registration statement on Form S-4 promulgated under the Securities Act (or on such other form as shall be appropriate) relating to the approval of the Agreement and the Mergers by the stockholders of Seller and shall use reasonable efforts to cause the Registration Statement to become effective as soon thereafter as practicable. The Proxy Statement/Prospectus shall include the recommendation of the Board of Directors of Seller in favor of the Mergers; provided, however, the Board of Directors of Seller may, at any time prior to such time as the stockholders of Seller shall have adopted and approved this Agreement and the Mergers in accordance with the DGCL, withdraw, modify or change any such recommendation to the extent Board of Directors of Seller determines in good faith, after consultation with its outside counsel, that the failure to so withdraw, modify or change its recommendation would reasonably be likely to constitute a failure of its Board of Directors to comply with its fiduciary duties under Delaware Law. Any withdrawal, modification or change of the recommendation in favor of the Mergers pursuant to this Section 6.1 shall be deemed by the parties not to change the approval of the Board of Directors of Seller for purposes of causing any business combination, control share acquisition, fair price or other anti-takeover law or regulation (including, without limitation, Section 203 of the DGCL) to be inapplicable to the Mergers and any such withdrawal, modification or change shall not affect Seller’s obligations in the first sentence of this Section 6.1, unless, in connection therewith, Seller terminates this Agreement in accordance with Section 8.1(g). The Company shall use commercially reasonable efforts to have the Registration Statement declared effective by the SEC as promptly as practicable and to maintain the effectiveness of the Registration Statement through the Effective Time. If, at any time prior to the Effective Time, the Company or Seller shall obtain knowledge of any information pertaining to the Company or Seller, as applicable, that would require an amendment or supplement to the Registration Statement, the Company or Seller, as the case may be, shall so advise the other party in writing and shall promptly furnish the other party with all information as shall be required for such amendment or supplement. Thereafter, the Company shall promptly take such action as shall be required to amend or supplement the Registration Statement; the Company shall not otherwise amend the Registration Statement without the consent of Seller (which shall not be unreasonably withheld, conditioned or delayed).

SECTION 6.2 Meeting of Seller’s Stockholders. Seller shall promptly after the date of this Agreement take all action necessary in accordance with the DGCL and the Seller Organizational Documents to convene the Seller Stockholders’ Meeting. Seller shall use its commercially reasonable efforts to solicit from stockholders of Seller proxies in favor of this Agreement and the Step One Merger and shall take all other action necessary or advisable to secure the vote or consent of stockholders required by the DGCL to approve this Agreement and the Step One Merger, unless the Board of Directors of Seller shall have determined in good faith, after consultation with its outside counsel, that such actions would be reasonably likely to constitute failure of the Board of Directors of Seller to comply with its fiduciary duties to stockholders imposed by Delaware Law.

SECTION 6.3 Appropriate Action; Consents; Filings.

(a) Seller and the Company shall use reasonable efforts to (i) take, or cause to be taken, all appropriate action, and do, or cause to be done, all things necessary, proper or advisable under applicable Law to consummate and make effective the transactions contemplated by this Agreement, (ii) obtain all consents, licenses, permits, waivers, approvals, authorizations or orders required under Law (including, without limitation, all foreign and domestic (federal, state and local) governmental and regulatory rulings and approvals and parties to contracts) required in connection with the authorization, execution and delivery of this Agreement and the consummation by them of the transactions contemplated hereby, including, without limitation, the Mergers, (iii) make all necessary filings, and thereafter make any other required submissions, with respect to this Agreement and the Mergers required under (A) the Securities Act and the Exchange Act and the rules and regulations thereunder, and any other applicable federal or state securities laws, (B) the applicable listing and corporate governance rules and regulations of NASDAQ, (C) the HSR Act and any other applicable antitrust laws and (D) any other applicable Law; provided that, the Company and Seller shall cooperate with each other in connection with the making of all such filings, including providing copies of all such documents to the non-filing party and its advisors prior to filing and, if requested, to accept all reasonable additions, deletions or changes suggested in connection therewith, and (iv) defend against any lawsuit or other proceeding, whether brought by a Governmental Authority or other third party, seeking to challenge this Agreement or the transactions contemplated hereby, including by seeking to have lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby. Seller and the Company shall furnish all information required for any application or other filing to be made pursuant to the rules and regulations of any applicable Law (including all information required to be included in the Proxy Statement/Prospectus and the Registration Statement) in connection with the transactions contemplated by this Agreement. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of each party to this Agreement shall use all reasonable efforts to take all such necessary action.

(b) Each of the Company and Seller shall keep the other reasonably informed of the status of their respective efforts to consummate the transactions contemplated hereby, including by (i) promptly notifying the other of, and if in writing, furnishing the other with copies of (or, in the case of material oral communications, advising the other orally of) any communications from or with any Governmental Authority (whether domestic, foreign or supranational) with respect to the transactions contemplated hereby, (ii) permitting the other to review and discuss in advance, and consider in good faith the views of the other in connection with, any proposed written (or any material proposed oral) communication with any such Governmental Authority, (iii) not participating in any meeting with any such Governmental Authority unless it consults with the other in advance and to the extent permitted by such Governmental Authority gives the other the opportunity to attend and participate thereat, (iv) furnishing the other with copies of all correspondence, filings and communications between it and any such Governmental Authority with respect to this Agreement and the transactions contemplated hereby, and (v) furnishing the other with such necessary information and reasonable assistance as each of them may reasonably request in connection with its preparation of necessary filings or submissions of information to any such Governmental Authority. Each of the Company and Seller may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 6.3(b) as “outside counsel only” and, in such event, such material and the information contained therein shall be given only to the outside legal counsel of the recipient and shall not be disclosed by such counsel to non legal directors, officers, employees or other advisors or representatives of the recipient unless express permission is obtained in advance from the source of the materials or its legal counsel.

SECTION 6.4 Third Party Consents. As soon as practicable following the date hereof, Seller will use all commercially reasonable efforts to obtain all Seller Approvals, including any consents, waivers and approvals under any of its or the Seller Subsidiaries’ respective agreements, contracts, licenses or leases, required to be obtained in connection with the consummation of the transactions contemplated hereby.

SECTION 6.5 Employee Benefit Matters. Annex A hereto sets forth certain agreements with respect to Seller’s employee benefit matters.

SECTION 6.6 Directors’ and Officers’ Indemnification and Insurance.

(a) From and after the Effective Time, the Company will, and will cause the Surviving Company to, fulfill and honor in all respects Seller’s obligations with respect to indemnification or exculpation provisions now existing in favor of any person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director, officer, employee or agent (an “Indemnified Party”) of Seller or any Seller Subsidiary as provided in the Seller Organizational Documents, the Subsidiary Organizational Documents, indemnification agreements of Seller or the Seller Subsidiaries with an Indemnified Party or otherwise in effect as of the date of this Agreement with respect to claims related to matters occurring prior to the Effective Time. Section 6.6(a) of the Seller Disclosure Letter contains a complete list of all indemnification agreements to which Seller is a party to on the date of this Agreement (the “Indemnification Agreements”). Seller agrees not to amend or enter into new Indemnification Agreements from and after the date hereof, except to the extent such Indemnification Agreements between Seller and certain of Seller’s officers who will become officers of the Surviving Company as a result of the Mergers will be amended by Seller to apply only to claims related to matters occurring prior to the Effective Time.

The Company will, and will cause the Surviving Company to, assume such policy, and the Company agrees to use its best efforts to maintain in effect such “tail” policy for the duration of its term without amendment or cancellation.

(c) The provisions of this Section 6.6 are intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and their heirs and personal representatives and shall be binding on the Company and the Surviving Company and its successors and assigns. In the event that the Company or the Surviving Company or its successor or assign (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each case, proper provision shall be made so that the successor and assign of Company or the Surviving Company, as the case may be, honor the obligations set forth with respect to the Company or the Surviving Company, as the case may be, in this Section 6.6.

SECTION 6.7 Section 16 Matters. Prior to the Effective Time, Seller shall take all such steps as may be required (to the extent permitted under applicable Law) to cause any dispositions of Seller’s Common Stock (including derivative securities with respect to Seller’s Common Stock) resulting from the transactions contemplated by Article I of this Agreement by each person who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Seller to be exempt under Rule 16b-3 promulgated under the Exchange Act.

The Company and Seller shall consult with each other before issuing any press release or otherwise making any public statements with respect to the Mergers and shall not issue any such press release or make any such public statement prior to such consultation, except (i) as may be required by Law, including disclosures required under the federal securities laws, or NASDAQ regulations or listing requirements, in which case the Company and Seller shall consult with each other before making any such public statements to the extent reasonably practicable, and (ii) that each of the Company and Seller may make public statements in response to specific questions by the press, analysts, investors or those attending industry conferences or financial analysts conference calls, so long as such statements are not inconsistent with previous press releases, public disclosures or public statements made jointly by the Company and Seller (or individually, if previously approved by the other party) and do not reveal non-public information regarding the other party.

SECTION 6.9 Expenses.

(a) All Expenses (as defined below) incurred in connection with this Agreement and the transactions contemplated hereby shall be borne solely and entirely by the party incurring such expenses.

(b) “Expenses” as used in this Agreement shall include all reasonable out-of-pocket expenses (including, without limitation, all fees and expenses of counsel, accountants, investment bankers, experts and consultants to the party and its affiliates) incurred by a party or on its behalf in connection with or related to the authorization, preparation and execution of this Agreement, the solicitation of shareholder approvals and all other matters related to the closing of the transactions contemplated hereby.

(c) Seller hereby agrees that, if this Agreement is terminated in accordance with Section 8.1(f) or Section 8.1(g), Seller shall promptly (and in any event within two days after such termination) pay the Company a fee of $2,500,000 by same day funds pursuant to electronic funds transfer.

(d) Each of the Company and Seller acknowledges that the agreements contained in this Section 6.9 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, neither the Company nor Seller would enter into this Agreement. Accordingly, if Seller fails to pay in a timely manner amounts due pursuant to Section 6.9(c), and, in order to obtain such payment, the Company makes a claim for such amounts that results in a judgment against Seller for the amounts described in Section 6.9(c), Seller shall pay to the Company its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts described in Section 6.9(c) (at the prime rate of ▇▇▇▇▇ Fargo Bank, N.A. in effect on the date such payment was required to be made) from such date until the payment of such amount (together with such accrued interest).

(d) any inaccuracy of any representation or warranty of that party contained in this Agreement at any time during the term of this Agreement that would reasonably be expected to cause the condition set forth in Section 7.2(a) or Section 7.3(a), as applicable, not to be satisfied; and

(e) any failure of that party to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, which failure or to comply or satisfy such covenant, condition or agreement would reasonably be expected to cause the condition set forth in Section 7.2(b) or Section 7.3(b), as applicable, not to be satisfied;

provided, however, that the delivery of any notice pursuant to this Section 6.10 shall not limit or otherwise affect the remedies available hereunder to the party receiving that notice.

(f) by the Company, if there shall exist a proposal for a Superior Competing Transaction with respect to Seller and the Board of Directors of Seller has withdrawn or modified in a manner adverse to the Company its approval and recommendation of this Agreement or its approval of the Mergers or any other transaction contemplated hereby or if the Board of Directors of Seller shall have approved or recommended such Superior Competing Transaction;

(g) by Seller, if Seller receives a proposal for a Superior Competing Transaction; or

(h) by either the Company or Seller, if the Mergers have not been consummated by noon Central Time on the End Date; provided, that the right to terminate this Agreement pursuant to this Section 8.1(h) shall not be available to any party if the failure to consummate the Mergers is the result of a breach of this Agreement by the party seeking to terminate this Agreement.

SECTION 8.2 Effect of Termination.

SECTION 8.4 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent other failure.
