EXHIBIT 2.01 AGREEMENT AND PLAN OF REORGANIZATION This Agreement and Plan of Reorganization (the "AGREEMENT") is entered into as of this 15th day of July, 1999, by and among Integrated Systems, Inc., a California corporation ("ACQUIRER"), ISI Acquisition Corporation, an Illinois corporation and a wholly owned subsidiary of Acquirer ("SUB"), Software Development Systems, Inc., an Illinois corporation, and the individuals listed on SCHEDULE A hereto (the "PRINCIPALS"). The term "Target" shall mean Software Development Systems, Inc., an Illinois corporation, and each of the entities set forth on SCHEDULE 2.4 hereto, taken as a whole. RECITALS A. The parties intend that, subject to the terms and conditions hereinafter set forth, Target will merge with and into Sub in a forward triangular merger (the "MERGER"), with Sub to be the surviving corporation of the Merger, pursuant to the terms and conditions of this Agreement and the Articles of Merger to be filed with the State of Illinois substantially in the form of EXHIBIT B attached hereto (the "ARTICLES OF MERGER") and the applicable provisions of the law of the State of Illinois. Upon the effectiveness of the Merger, all of the outstanding Common Stock of Target will be converted into Common Stock of Acquirer ("ACQUIRER COMMON STOCK"). In addition, all outstanding options ("TARGET OPTIONS") will be converted into options to purchase Acquirer Common Stock, all as provided in this Agreement and the Articles of Merger. All debt instruments which by their terms are convertible into or exchangeable for equity securities of Target ("TARGET CONVERTIBLE DEBT") will be treated as set forth in Section 1.1.1(v). B. The Merger is intended to be treated as a tax-free reorganization pursuant to the provisions of Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the "CODE"), by virtue of the provisions of Section 368(a)(2)(D) of the Code, and as a "purchase" for accounting purposes. C. The parties intend that the Total Acquirer Shares (as defined below) will be the total amount of Acquirer Common Stock issued or issuable for all of Target's outstanding Common Stock, options to purchase Common Stock and any other equity interests or rights in Target of any type whatsoever. NOW, THEREFORE, the parties hereto hereby agree as follows: 1. PLAN OF REORGANIZATION 1.1 THE MERGER. The Articles of Merger will be filed with the office of the Secretary of State of Illinois, as soon as practicable after the Closing Date (as defined in Section 6.1 hereof). The effective date and time of the last such filing is referred to herein as the "EFFECTIVE TIME". At the Effective Time, Target will be merged with and into Sub pursuant to this Agreement and the Articles of Merger in accordance with applicable provisions of the law of the State of Illinois as follows: 1.1.1 CONVERSION OF SHARES. Each share of Target Common Stock (the "TARGET COMMON STOCK") issued and outstanding immediately prior to the Effective Time, other than shares, if any, for which dissenters rights have been or will be perfected in compliance with applicable law, will by virtue of the Merger and at the Effective Time, and without further action on the part of any holder thereof (the "TARGET SHAREHOLDER(S)"), be converted into the right to receive (a) the "PER SHARE CASH PAYMENT" and (b) the "APPLICABLE FRACTION" of a fully paid and nonassessable share of Acquirer Common Stock from Acquirer. (i) PURCHASE PRICE. The "Purchase Price" shall be Forty Million Six Hundred Thousand Dollars ($40,600,000) LESS the cash payable to holders of Target Options pursuant to Section 1.1.2 below and LESS any adjustment due to unconverted or repaid Target Convertible Debt pursuant to Section 1.1.1(v) below. (ii) THE PER SHARE CASH PAYMENT. The Per Share Cash Payment shall be determined by dividing the Purchase Price by 2 (the "CASH PURCHASE PRICE") and then dividing the Cash Purchase Price by the Target Common Stock (as defined above). The Cash Purchase Price shall be subject to adjustment pursuant to Sections 1.1.1(iii)(B) and (C) below. (iii) THE TOTAL ACQUIRER SHARES. The total shares of Acquirer Common Stock issuable hereunder (the "TOTAL ACQUIRER SHARES") shall be determined by dividing the Purchase Price by 2 (the "STOCK PURCHASE PRICE") and then dividing the Stock Purchase Price by the Nasdaq National Market closing prices of Acquirer's Common Stock on the most recent ten (10) trading days immediately prior to the date of this Agreement (the "PER SHARE MARKET VALUE") subject to the following adjustments. (A) If the Per Share Market Value exceeds $15.60, the Total Acquirer Shares will be calculated by dividing the Stock Purchase Price by $15.60. (B) If the Per Share Market Value is less than $10.40, the Total Acquirer Shares will be calculated as the sum of the result of dividing the Acquirer Stock Purchase Price by $10.40 and (ii) such number, if any, of additional shares that are necessary to have the Stock Purchase Price equal one-half of the sum of (A) the number of shares prior to such adjustment multiplied by the Per Share Market Value and (B) the Cash Purchase Price prior to adjustment pursuant to Section 1.1.1(iii)(B) herein. In the event an adjustment is necessary pursuant to clause (ii), then the Cash Purchase Price shall be reduced to equal the product of (1) the Per Share Market Value and (2) the number of Target Acquirer Shares, after the adjustments set forth in clause (ii) above. Notwithstanding anything to the contrary herein, in no event shall Acquirer be required to issue more shares than Nineteen and Nine Tenths Percent (19.9%) of the total number of outstanding shares of its Common Stock immediately prior to the Closing. In addition, the Cash Purchase Price shall only exceed the Stock Purchase Price upon the approval of each of Acquirer and Target, in which case the provisions, terms and conditions contained in this Agreement, the Acquirer Ancillary Agreements and the Target Ancillary Agreements 2 relating to the tax-free treatment of the Merger shall no longer be applicable with respect to any party. (C) If the Per Share Market Value is greater than the last reported sale price of Acquirer's Common Stock on the trading day immediately prior to the Effective Time (the "EFFECTIVE TIME PRICE"), then the Cash Purchase Price shall then be reduced to equal the product of (x) the number of Total Acquirer Shares as determined pursuant to this Section 1.1.1(iii) multiplied by (y) the Effective Time Price. (iv) APPLICABLE FRACTION. The Applicable Fraction shall be determined by dividing (A) the Total Acquirer Shares (as defined above in Subsection 1.1.1(iii)) by (B) the total number of shares of Target Common Stock outstanding immediately prior to the Effective Time. (v) ADJUSTMENT TO PURCHASE PRICE. To the extent that any Target Convertible Debt remains unconverted at the Effective Time because the holder declines to convert such debt as listed on SCHEDULE 1.1.1(iv) hereto, Acquirer agrees to assume the obligation of paying such unconverted Target Convertible Debt in accordance with the terms thereof. The Purchase Price shall be reduced by the amount of the principal and interest of such obligation that was repaid prior to the Effective Time or that is assumed by Acquirer. Any attempt to make an election to convert the debt after the Effective Time to Target Common Stock shall be invalid and will not be honored by Acquirer. Any fractional shares shall be handled in accordance with Section 1.2 hereof. 1.1.2 TARGET OPTIONS TREATMENT. Each share of Target Common Stock issuable upon the exercise of Target Options will, by virtue of the Merger and at the Effective Time, and without any action on the part of the holder thereof, be converted into the right of the holder thereof to receive a cash payment from Acquirer an amount equal to the difference between: (i) the result obtained from dividing (A) Forty Million Six Hundred Thousand Dollars ($40,600,000) less any adjustment to the Purchase Price due to unconverted or repaid Target Convertible Debt pursuant to Section 1.1.1(v) above by (B) the sum of the total number of shares of Target Common Stock and the total number of shares of Target Common Stock issuable upon exercise of all Target Options outstanding immediately prior to the Effective Time; and (ii) the exercise price per share of such Target Option. Any fractional shares shall be handled in accordance with Section 1.2 hereof. 1.1.3 ADJUSTMENTS FOR CAPITAL CHANGES. If prior to the Effective Time, Acquirer recapitalizes through a split-up of its outstanding shares into a greater number, or a combination of its outstanding shares into a lesser number, reorganizes, reclassifies or otherwise changes its outstanding shares into the same or a different number of shares of other classes (other than through a split-up or combination of shares provided for in the previous clause), or declares a dividend on its outstanding shares payable in shares or securities convertible into shares, the 3 number of shares of Acquirer Common Stock into which the shares of Target Common Stock, Target Options and Target Convertible Debt (that elects to convert into Acquirer Common Stock at the Effective Time) are to be converted will be adjusted appropriately so as to maintain the proportionate interests of the holders of the Target Common Stock, Options and Target Convertible Debt (that elects to convert into Target Common Stock at or prior to the Effective Time) and the holders of Acquirer shares. 1.1.4 DISSENTING SHARES. Holders of shares of Target Common Stock who have complied with all requirements for perfecting dissenter's rights, as set forth in the general corporation law of the State of Illinois ("ILLINOIS LAW"), shall be entitled to their rights under the Illinois Law with respect to such shares ("DISSENTING SHARES"). 1.2 FRACTIONAL SHARES. No fractional shares of Acquirer Common Stock will be issued in connection with the Merger, but in lieu thereof, the holder of any shares of Target Common Stock who would otherwise be entitled to receive a fraction of a share of Acquirer Common Stock will receive from Acquirer, promptly after the Effective Time, an amount of cash equal to (i) the Per Share Market Value, as determined in Subsection 1.1.1(i) above, multiplied by (ii) the fraction of a share to which such holder would otherwise be entitled. 1.3 ESCROW AGREEMENT. At the Closing of the Merger (as defined in Section 6.1 hereof), Acquirer will withhold (i) that number of shares of Acquirer Common Stock which equals five percent (5%) of the sum of the Total Acquirer Shares (as defined in Section 1.1.2 hereof) on a pro rata basis among each Material Target Shareholder (as defined below), as determined pursuant to this Section 1.3 (rounded down to the nearest whole number of shares to be issued to each Material Target Shareholder) (the "ESCROW SHARES") and (ii) five percent (5%) of the Cash Purchase Price (after any adjustments pursuant to Section 1.1.1(iii)(B) hereof) (the "ESCROW CASH" and, together with the Escrow Shares, the "ESCROW CASH AND SHARES") and deliver the Escrow Cash and Shares to Chase Manhattan Bank and Trust Company, National Association (the "ESCROW AGENT"), as escrow agent, to be held by the Escrow Agent as collateral for the Material Target Shareholder's obligations under Section 10.2 and pursuant to the provisions of an escrow agreement (the "ESCROW AGREEMENT") in substantially the form of EXHIBIT 1.3. The Escrow Shares will be represented by a certificate or certificates issued in the name of the Material Target Shareholders and delivered to the Escrow Agent and, along with the Escrow Cash, will be held as collateral for Damages suffered by an Indemnified Person (each as defined in Section 10.2) for breaches of the representations, warranties and covenants of Target contained in this Agreement. The Escrow Cash and Shares will be delivered and will be held by the Escrow Agent from the Closing until the first anniversary of the Effective Time (the "ESCROW PERIOD"). However, in all cases as to matters which an Indemnified Person has given written notice of a claim for Damages during the Escrow Period, Escrow Agent shall disburse to the Material Target Shareholders such lesser amount as is sufficient to pay such claims in accordance with the terms of this Agreement and the Escrow Agreement. In the event that the Merger is approved by the Target Shareholders, as provided herein, the Material Target Shareholders shall, without any further act of any Material Target Shareholder, be deemed to have consented to and approved (i) the use of the Escrow Cash and 4 Shares as collateral for the Material Target Shareholder's indemnification obligations under Section 10.2 in the manner set forth in the Escrow Agreement, (ii) the appointment of James E. Challenger as the representative of the Material Target Shareholders ( the "REPRESENTATIVE") under the Escrow Agreement and as the attorney-in-fact and agent for and on behalf of each Material Target Shareholder (other than holders of Dissenting Shares), and the taking by the Representative of any and all actions and the making of any decisions required or permitted to be taken by the Representative under the Escrow Agreement (including, without limitation, the exercise of the power to: (a) authorize delivery to Acquirer of Escrow Cash and Shares in satisfaction of claims by Acquirer; (b) agree to, negotiate, enter into settlements and compromises of and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims; (c) resolve any claim made by Indemnified Persons pursuant to Section 10.2; and (d) take all actions necessary in the judgment of the Representative for the accomplishment of the foregoing) and (iii) to all of the other terms, conditions and limitations in the Escrow Agreement. All actions, decisions and instructions of the Representative including, without limitation, the defense or settlement of any claims for which the Material Target Shareholders may be required to indemnify Acquirer or Sub pursuant to Section 9.2 hereof, shall be conclusive and binding upon all of the Material Target Shareholders and no shareholder shall have any right to object, dissent, protest or otherwise contest the same or have any cause of action against the Representative for any action taken, decision made or instruction given by the Representative under this Agreement, except for fraud or willful breach of this Agreement by the Representative. The provisions of this paragraph are independent and severable, are irrevocable and coupled with an interest and shall be enforceable notwithstanding any rights or remedies that any shareholder may have in connection with the transactions contemplated by this Agreement. The provisions of this paragraph shall be binding upon the executors, heirs, legal representatives, successors and assigns of each such shareholder, and any references in this Agreement to a Material Target Shareholder or the Material Target Shareholders shall include the successors to the Material Target Shareholders' rights hereunder, whether pursuant to assignment, testamentary disposition, the laws of descent, and distribution or otherwise. In acting as the representative of the Material Target Shareholders, the Representative may rely upon, and shall not be liable to any shareholder for acting or refraining from acting upon, an opinion of counsel, certificate of auditors or other certificate, statement, instrument, opinion, report, notice, request, consent, order, arbitrator's award, appraisal, bond or other paper or document reasonably believed by him to be genuine and to have been signed or presented by the proper party or parties. The Representative shall incur no liability to any Material Target Shareholder with respect to any action taken or suffered by him in his capacity as Representative in reliance upon any note, direction, instruction, consent, statement or other documents believed by him to be genuinely and duly authorized, nor for other action or inaction except his own willful misconduct or gross negligence and the Representative shall be indemnified and saved harmless by the shareholders from all losses, costs and expenses which the Representative may incur as a result of involvement in any legal proceedings arising from the performance of his or her duties hereunder. The Representative may perform his duties as Representative either directly or by or through his agents or attorneys and the Representative shall not be responsible to the other Material Target Shareholders for any misconduct or negligence on the part of any agent or 5 attorney appointed with reasonable care by him hereunder. All fees and expenses incurred by the Representative in connection with this Agreement shall be paid by the Material Target Shareholders in proportion to their respective Pro Rata Percentages. For purposes of this Agreement, "Material Target Shareholders" shall mean all Target Shareholders, excluding Jeffrey Barth. 1.4 EFFECTS OF THE MERGER. At the Effective Time: (a) the separate existence of Target will cease and Target will be merged with and into Sub, and Sub will be the surviving corporation, pursuant to the terms of the Articles of Merger, (b) each share of Target Common Stock outstanding immediately prior to the Effective Time and the Target Convertible Debt that elects to convert into Target Common Stock at or prior to the Effective Time will be converted into Acquirer Common Stock, each as provided in Sections 1.1 and 1.2, (c) the Merger will, from and after the Effective Time, have all of the effects provided by applicable law (d) the Certificate of Incorporation and Bylaws of Target in effect immediately prior to the Effective Time shall be the Certificate of Incorporation and Bylaws, respectively, of the surviving corporation after the Effective Time unless and until further amended as provided by law (e) the directors and officers of the Surviving Corporation after the Effective Time shall be as set forth on SCHEDULE 1.4 hereto. Such directors and officers shall hold their position until the election and qualification of their respective successors or until their tenure is otherwise terminated in accordance with the Bylaws of the surviving corporation. 1.5 S-3 REGISTRATION RIGHTS. Effective upon the Effective Time, each Target Shareholder who receives shares of Acquirer Common Stock, including shares issued to holders of Target Convertible Debt that elect to convert into Target Common Stock at or prior to the Effective Time, in the Merger pursuant to Section 1.1 hereof shall be granted Form S-3 registration rights under the Securities Act of 1933, as amended (the "1933 ACT") on the terms and subject to the conditions and limitations of the Registration Rights Agreement attached hereto as EXHIBIT 1.5 (the "REGISTRATION RIGHTS AGREEMENT"). Within ninety (90) days of the Closing, Acquirer will cause to be filed a Registration Statement on Form S-3 covering the resale of all securities issued in the Merger, including shares to holders of Target Convertible Debt that converted into Target Common Stock at or prior to the Effective Time. Acquirer will use its best efforts to cause the Registration Statement to become effective promptly after filing and shall keep such Registration Statement effective until such time as each recipient of Acquirer Common Stock is eligible to sell all of the Acquirer Common Stock held by each such recipient in a three (3) month period pursuant to the resale restrictions provided for in Rule 144 under the 1933 Act. In order to enforce the foregoing covenants, Acquirer shall have the right to place restrictive legends on the certificates of the Acquirer Common Stock issued in the Merger, indicating that the shares are subject to the provisions of the Registration Rights Agreement until the sale of such shares. 1.6 QUALIFY AS A TAX-FREE REORGANIZATION. The parties intend to adopt this Agreement as a plan of reorganization and to consummate the Merger in accordance with the provisions of Section 368(a)(1)(A) of the Code. The parties believe that the total value to be received in the Merger by the Target Shareholders is equal, in each instance, to the total value of the Target Common Stock to be surrendered in exchange therefor. The Total Acquirer Shares and the Cash 6 Purchase Price will be exchanged solely for Target Common Stock, Target Options and Target Convertible Debt that elects to convert into Target Common Stock at or prior to the Effective Time, respectively, and no other transaction other than the Merger represents, provides for or is intended to be an adjustment to the consideration paid for the Target Common Stock, Target Options and Target Convertible Debt that elects to convert into Acquirer Common Stock at or prior to the Effective Time. Except for the Cash Purchase Price and cash paid in lieu of fractional shares or for Dissenting Shares, no consideration that could constitute "other property" within the meaning of Section 356 of the Code is being paid by Acquirer for the Target Common Stock in the Merger. The parties shall not take a position on any tax returns inconsistent with this Section 1.6 unless required to do so by applicable tax laws pursuant to a determination as defined in Section 1313(c) of the Code. In addition, Acquirer represents now, and as of the Closing Date, that it presently intends to continue Target's historic business or use a significant portion of Target's business assets in a business. At the Closing, the Chief Financial Officers of Acquirer and Target shall each execute and deliver tax certificates in the forms of EXHIBITS 1.6A-B, together with an acknowledgment that such certificates will be relied upon by Target and Acquirer in determining whether the Merger constitutes a reorganization under Section 368(a) of the Code. The provisions and representations contained or referred to in this Section 1.6 shall survive until the expiration of the applicable statute of limitations. 2. REPRESENTATIONS AND WARRANTIES OF TARGET AND PRINCIPALS Target and the Principals, severally and in accordance with their respective pro rata shares (but not jointly and severally), hereby represent and warrant as follows, except as set forth in the Target Disclosure Schedule delivered to Acquirer by Target prior to the execution of this Agreement, as SCHEDULE 2.0: 2.1 ORGANIZATION AND GOOD STANDING.

Neither the execution and delivery by Target of this Agreement nor of any Target Ancillary Agreement, nor the consummation by Target of the transactions contemplated hereby or thereby, will conflict with, or (with or without notice or lapse of time, or both) result in a termination, breach, impairment or violation of (a) any provision of the Articles of Incorporation or Bylaws of Target, as currently in effect, (b) in any material respect, any Material Agreement (as defined in Section 2.11) to which Target is a party or by which Target is bound, or (c) any federal, state, local or foreign judgment, writ, decree, order, statute, rule or regulation known to Target to be applicable to Target or its assets or properties, except, in each case, where such conflict, termination, breach, impairment or violation would not have a Material Adverse Effect.

There is no action, proceeding, claim or investigation pending against Target before any court or administrative agency that if determined adversely to Target may reasonably be expected to have a Material Adverse Effect or to prevent Target from fulfilling its obligations under this Agreement; nor to Target's or any Principal's knowledge, has any such action, proceeding, claim or investigation been threatened. There is, to Target's and each Principals' knowledge, no reasonable basis for any shareholder or former shareholder of Target, or any other person, firm, corporation, or entity, to assert a claim against Target or Acquirer based upon: (a) ownership or rights to ownership of any shares of Target Common Stock (except for dissenter's rights with respect to shares of Acquirer Common Stock issuable by virtue of the Merger), (b) any rights as an Target Shareholder, including any option or preemptive rights or rights to notice or to vote, or (c) any rights under any agreement among Target and the Target Shareholders. 2.7 TAXES. Target has timely filed all federal, state, local and foreign tax returns, estimates, information statements and reports required to be filed by or on behalf of Target and its operations (collectively, "RETURNS"), has timely paid all taxes shown due on all Returns which have been filed, has established an adequate accrual or reserve for the payment of all taxes, due and payable, including reasonable accruals for taxes payable in respect of the periods subsequent to the periods covered by the most recent applicable Returns, has made all necessary estimated tax payments, and has no material liability for taxes in excess of the amounts so paid or accruals or reserves so established. Target has filed with all applicable taxing authorities or applied for extensions with respect to tax returns for the most recently completed fiscal year. Target is not delinquent in the payment of any tax nor delinquent in the filing of any returns or other required documents (including but not limited to the filing of financial statements with any foreign taxing authorities), and there are no deficiencies for any tax and there are currently no taxes claimed, assessed or, to Target's or any Principal's knowledge, threatened, by any taxing authority. Target has not executed any waiver of any statute of limitations on or extending the period for the assessment or collection of any tax. Target has not received any notification that any material issues have been raised (and are currently pending) by the Internal Revenue Service or any other 9 taxing authority (including but not limited to any foreign state or sales tax authority) regarding Target. No tax return of Target has ever been audited by the Internal Revenue Service or any foreign or state taxing agency or authority. Target has provided to Acquirer copies of all foreign, federal and state income Returns for Target's 1996 and 1997 fiscal years. There are no liens, pledges, charges, claims, security interests or other encumbrances of any sort on the assets of Target relating to or attributable to taxes, other than liens for taxes not yet due and payable. There is no contract, agreement, plan or arrangement, including but not limited to the provisions of this Agreement, covering any employee or former employee of Target that, individually or collectively, could give rise to the payment of any amount that would be disallowed pursuant to Section 280G or 162(m) of the Code. Target is not a party to a tax sharing or allocation agreement nor does Target owe any amount under any such agreement. Target is not, and has not been at any time, a "United States real property holding corporation" within the meaning of Section 897(c)(2) of the Code. Target has not filed any consent agreement under Section 341(f) of the Code or agreed to have Section 341(f)(2) of the Code apply to any disposition of a subsection (f) asset (as defined in Section 341(f)(4) of the Code) owned by Target. None of Target's assets are treated as "tax-exempt use property" within the meaning of Section 168(h) of the Code. For the purposes of this Agreement, the terms "TAX" and "TAXES" include all federal, state, local and foreign income, gains, franchise, excise, property, sales, use, employment, license, payroll, occupation, recording, value added or transfer taxes, governmental charges, fees, levies or assessments (whether payable directly or by withholding), and, with respect to such taxes, any estimated tax, interest and penalties or additions to tax and interest on such penalties and additions to tax. Without limiting any of the foregoing, Target's inter-company transfer prices have been within five percent (5.0%) of those paid by any of Target's distributors. Target has not been a distributing corporation within the prior two (2) years in a transaction intending to qualify as a tax-free distribution under Section 355 of the Code. 2.8 TARGET FINANCIAL STATEMENTS. Target has delivered to Acquirer as SCHEDULE 2.8 Target's (a) audited balance sheet as of December 31, 1998 (the "1998 BALANCE SHEET") and income statement and statement of cash flows for the twelve (12) month period then ended (collectively, the "1998 FINANCIAL STATEMENTS"), and (b) unaudited balance sheet as of May 31, 1999 (the "MAY 31 BALANCE SHEET") and income statement and statement of cash flows for the five (5) month period then ended (collectively, the "MAY FINANCIAL STATEMENTS") (the 1998 Financial Statements and May Financial Statements are collectively referred to herein as the "Financial Statements"). The Financial Statements have been prepared based upon with the books and records of Target and fairly present the financial condition of Target at the dates therein indicated and the results of operations for the periods therein specified in all material respects. The Financial Statements have been prepared in accordance with generally accepted accounting principles applied on a consistent basis (except, with respect to the May Financial Statements, for the absence of footnotes and as to the effect of normal year end adjustments). To the knowledge of Target and each Principal, Target has no material debt, liability or obligation of any nature, whether accrued, absolute, contingent or otherwise, and whether due or to become due, that is not reflected or reserved against in the Financial Statements which would be required under generally accepted accounting principles to be reflected or reserved, except for those that may have been incurred after the date of the Financial Statements in the ordinary course of its business, consistent with past practice and that are not material in amount either individually or 10 collectively. Without limiting the foregoing, Target represents that the refundable tax assets described in the Financial Statements are accurate in all material respects. 2.9 TITLE TO PROPERTIES. Except as set forth on Schedule 2.9, Target has good and marketable title to or a leasehold or other rights to use all of its assets as shown on the May 31 Balance Sheet, free and clear of all liens, charges, restrictions or encumbrances (other than for taxes not yet due and payable) in excess of twenty five thousand dollars ($25,000) in the aggregate.

The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby will not constitute a material breach of any instrument or agreement governing any Target IP Right (the "TARGET IP RIGHTS AGREEMENTS"), will not cause the forfeiture or termination or give rise to a right of forfeiture or termination of any Target IP Right or materially impair the right of Target to use, sell or license any Target IP Right or portion thereof (except where such breach, forfeiture or termination would not have a material adverse effect on Target, taken as a whole). There are no royalties, honoraria, fees or other payments payable by Target to any person by reason of the ownership, use, license, sale or disposition of the Target IP Rights (other than as set forth in the Target IP Rights Agreements listed in SCHEDULE 2.12). Neither the manufacture, marketing, license or sale of any product currently licensed or sold by Target or currently under development by Target violates any license or agreement between Target and any third party or infringes any Intellectual Property Right of any other party; and there is no pending or, to the knowledge of Target and the Principals, threatened claim or litigation contesting the validity, ownership or right to use, sell, license or dispose of any Target IP Right; nor, to the knowledge of Target and the Principals is there any basis for any such claim; nor has Target received any notice asserting that any Target IP Right or the proposed use, sale, license or disposition thereof conflicts or will conflict with the rights of any other party, nor, to the knowledge of Target and the Principals is there any reasonable basis for any such assertion. Target has taken commercially reasonable and practicable steps designed to safeguard and maintain the secrecy and confidentiality of, and its proprietary rights in, all material Target IP Rights. SCHEDULE 2.12 contains a list of all applications, registrations, filings and other formal actions made or taken pursuant to federal, state and foreign laws by Target to perfect or protect its interest in Target IP 13 Rights, including, without limitation, all issued patents, patent applications, registered copyrights, copyright applications, registered trademarks, trademark applications, registered tradenames, issued service marks, service mark applications and all Target IP Rights Agreements (except for object code end-user licenses granted to end-users in the ordinary course of business that permit use of software products without a right to modify, distribute or sublicense the same). Target has disclosed all information material to the applications, registrations and filings listed in SCHEDULE 2.12 to the appropriate government agencies, and has properly complied with all procedural requirements pertaining to the preparation and filing of such applications, registrations and filings. As used herein, the term "INTELLECTUAL PROPERTY RIGHTS" shall mean all industrial and intellectual property rights in any jurisdiction in the world, including, without limitation, patents, patent applications, patent rights, trademarks, trademark applications, trade names, service marks, service mark applications, copyright, copyright applications, moral rights, franchises, licenses, inventories, know-how, trade secrets, customer lists, proprietary processes and formulae, all source and object code, algorithms, architecture, structure, display screens, layouts, inventions, development tools and all documentation and media constituting, describing or relating to the above, including, without limitation, manuals, memoranda and records. 2.13 COMPLIANCE WITH LAWS. Target is or will be at the Closing Date in full compliance, in all material respects with all applicable laws, ordinances, regulations, and rules, and all orders, writs, injunctions, awards, judgments, and decrees applicable to it or to the assets, properties, and business thereof (the violation of which would have a Material Adverse Effect), including, without limitation: (a) all applicable federal and state and foreign securities laws and regulations, (b) all applicable federal, state, local and foreign laws, ordinances, regulations, and all orders, writs, injunctions, awards, judgments, and decrees pertaining to (i) the sale, licensing, leasing, ownership, or management of its owned, leased or licensed real or personal property, products and technical data, (ii) employment and employment practices, terms and conditions of employment, and wages and hours and (iii) safety, health, fire prevention, environmental protection, toxic waste disposal, building standards, zoning and other similar matters (c) the Export Administration Act and regulations promulgated thereunder and all other laws, regulations, rules, orders, writs, injunctions, judgments and decrees applicable to the export or re-export of controlled commodities or technical data and (d) the Immigration Reform and Control Act.

All Target Employee Plans which individually or collectively would constitute an "employee pension benefit plan," as defined in Section 3(2) of ERISA (collectively, the "TARGET PENSION PLANS"), are identified as such in SCHEDULE 2.15.3. All contributions due from Target prior to the Closing Date with respect to any of the Target Employee Plans have been or will be made prior to such Closing Date or have otherwise been accrued on Target's financial statements as required by generally accepted 15 accounting principles and all such contributions have or will be made in accordance with ERISA. Each Target Employee Plan has been maintained substantially in compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations, including, without limitation, ERISA and the Code, which are applicable to such Target Employee Plans. 2.15.4 No "prohibited transaction," as defined in Section 406 of ERISA or Section 4975 of the Code, has occurred with respect to any Target Employee Plan which is covered by Title I of ERISA which would result in a material liability to Target taken as a whole, excluding transactions effected pursuant to (or covered by) a statutory, regulatory or administrative exemption. Neither Target nor any of its officers or directors have engaged in any transaction or acted or failed to act in any manner that violates the fiduciary requirements of ERISA with respect to any Target Employee Plan and that would subject Target or any of its officers or directors to a material liability. No event or omission has occurred in connection with any Target Employee Plan that would make Target or any of its officers or directors liable for any material tax (as defined in Section 2.7) or material penalty pursuant to Sections 4972, 4975, 4976 or 4979 of the Code or Section 502 of ERISA. 2.15.5 Except as set forth in SCHEDULE 2.15.5, any Target Pension Plan which is intended to be qualified under Section 401(a) of the Code has received a favorable determination from the Internal Revenue Service that the Plan document for such Target Pension Plan satisfies the requirements for qualification, and Target is not aware of any reason why such determination may not be relied upon by such plan (other than changes in the law resulting from the Small Business Job Protection Act of 1996 and the Taxpayers Relief Act of 1997). 2.15.6 SCHEDULE 2.15.6 lists each employment, severance or other similar contract, arrangement or policy and each plan or arrangement (written or oral) providing for insurance coverage (including any self-insured arrangements), workers' benefits, vacation benefits, severance benefits, disability benefits, death benefits, hospitalization benefits, retirement benefits, deferred compensation, profit-sharing, bonuses, stock options, stock purchase, phantom stock, stock appreciation or other forms of incentive compensation or post-retirement insurance, compensation or benefits for employees, consultants or directors which (A) is not a Target Employee Plan, (B) is entered into, maintained or contributed to, as the case may be, by Target and (C) covers any employee or former employee of Target. Such contracts, plans and arrangements as are described in this Section 2.15.6 are herein referred to collectively as the "TARGET BENEFIT ARRANGEMENTS." Each Target Benefit Arrangement has been maintained in substantial compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations which are applicable to such Target Benefit Arrangement.

To the knowledge of Acquirer, Sub and their respective Affiliates, there are no situations that would prevent the treatment of the Merger as a reorganization qualifying under the provisions of Section 368(a) of the Code.

Reg. Sec. 1.1502-80(b)).
