EXHIBIT 10.02 NON-COMPETITION AGREEMENT This Non-Competition Agreement (this "AGREEMENT") is made and entered into as of July 15, 1999 (the "EXECUTION DATE") by and between Integrated Systems, Inc., a California corporation (the "COMPANY"), and James E. Challenger ("SHAREHOLDER"). R E C I T A L S A. The Company and Software Development Systems, Inc., an Illinois corporation ("SDS"), have entered into an Agreement and Plan of Reorganization dated as of July 15, 1999 (the "PLAN"), pursuant to which SDS will merge with a subsidiary of the Company in a statutory merger (the "MERGER"), pursuant to the terms and conditions set forth in the Plan and applicable law. Capitalized terms that are used in this Agreement and are not defined herein shall have the same meanings that such terms have in the Plan. B. Upon the effectiveness of the Merger, the outstanding Common Stock of SDS will be converted into shares of the Company Common Stock, in the manner and on the basis set forth in the Plan. C. Shareholder is a principal shareholder of SDS, owns Common Stock of SDS and is an officer and key employee of SDS, and upon the effectiveness of the Merger, will receive shares of the Company Common Stock having substantial value by virtue of the exchange of Shareholder's SDS shares in the Merger. Shareholder's talents and abilities are critical to SDS's ability to successfully carry on its business. D. One of the material conditions precedent to the obligation of the Company to consummate the Merger under the Plan is that Shareholder has executed, entered into and is bound by this Agreement with the Company. Shareholder is therefore entering into this Agreement as a material inducement and consideration to the Company to enter into the Plan, to issue the consideration payable to the SDS shareholders in the Merger, to consummate the Merger and for the other consideration stated herein. E. Shareholder is also receiving additional consideration as set forth in this Agreement. NOW, THEREFORE, in consideration of the facts stated in the foregoing recitals and the promises made herein, the Company and Shareholder hereby agree as follows: 1. EFFECTIVENESS OF OBLIGATIONS. This Agreement shall become effective if and only if the Merger is consummated on or before July 31, 1999, and shall become effective upon the date that the Merger is consummated and becomes legally effective (such date being hereinafter referred to as the "EFFECTIVE TIME"). 2. CERTAIN DEFINITIONS. (a) COVENANT PERIOD. As used herein, the term "COVENANT PERIOD" means that period of time commencing on the Effective Time and ending on the LATER of (i) the fourth (4th) anniversary of the Effective Time; or (ii) the "Termination Date" (as defined herein).

Shareholder hereby acknowledges that the identities, addresses, and business needs of the past, current, prospective clients and customers of the Company, SDS, the Surviving Corporation and their Affiliates are confidential and proprietary information and trade secrets of the Company and the Surviving Corporation, respectively, and that this Agreement imposes on Shareholder a duty not to disclose such information or use such information to the detriment of the Company or the Surviving Corporation or their Affiliates in violation of this Agreement.

Shareholder acknowledges and agrees with the Company that all such confidential information and trade secrets previously received or to be received by Shareholder from SDS, the Company, the Surviving Corporation or any of their respective Affiliates was or will be received by Shareholder in confidence and as a fiduciary.

If Shareholder becomes an employee of the Company, the Surviving Corporation or any other Affiliate of the Company as a result of the Merger, Shareholder agrees to execute and deliver any standard invention assignment and confidentiality agreement normally required for the Company employees. 3 6. OPINION OF THE COMPANY. If Shareholder desires to engage in any activity and is uncertain whether such activity is prohibited by this Agreement, then Shareholder shall describe the proposed activity in detail in a written notice to the Company delivered by personal delivery or by first class certified or registered mail, return receipt requested, addressed to the Company's President or Chief Executive Officer. The Company shall have thirty (30) days after receipt of such notice during which to advise Shareholder whether the Company believes that the proposed activity is prohibited by this Agreement. If the Company fails to notify Shareholder of its determination during such thirty (30) day period, or if the Company notifies Shareholder that it has no objection to all or a portion of the proposed activity, then Shareholder may engage in all or such portion of such activity, as the case may be, without any liability to the Company under this Agreement. 7. SEVERABILITY. The scope and effect of the covenants of Shareholder in this Agreement shall be as broad in time (but not, as regards the covenants contained in Section 3 of this Agreement, beyond the applicable time periods set forth therein), geography and in all other respects as is permitted by applicable law. Should a court or other body of competent jurisdiction determine that any term or provision of this Agreement is excessive in scope or duration or is unenforceable, then such term or provision shall not be voided or made unenforceable, but rather shall be modified so as to be enforceable, in accordance with the purposes stated in the preceding sentence and with applicable law, and all other terms and provisions of this Agreement shall remain valid and fully enforceable. 8. REMEDIES. Shareholder acknowledges and agrees with the Company that damages would not adequately compensate the Company if Shareholder were to breach any of covenants of Shareholder contained in this Agreement. Consequently, Shareholder agrees that in the event of any such breach, the Company shall be entitled, in addition to any other remedies, to enforce this Agreement by means of an injunction or other equitable relief. 9. SURVIVING CORPORATION IS THIRD PARTY BENEFICIARY. Shareholder and the Company acknowledge and agree that the Surviving Corporation is an intended third party beneficiary of this Agreement insofar as the Surviving Corporation may seek to enforce Shareholder's obligations under this Agreement against Shareholder; PROVIDED, HOWEVER, that the Surviving Corporation may act to enforce this Agreement only with the Company's prior written consent. 10.
