1 EXHIBIT 4.23 EMPLOYMENT AGREEMENT THIS EMPLOYMENT AGREEMENT (the "AGREEMENT"), dated as of the 20th day of August, 1997 the ("EFFECTIVE DATE"), by and between ILOG, Inc., a California corporation (the "COMPANY") and the undersigned employee ("EMPLOYEE") of Company. AGREEMENT NOW, THEREFORE, IT IS HEREBY AGREED by and among the parties hereto as follows: 1. EMPLOYMENT BY COMPANY; DUTIES. (a) Employment. Subject to the terms and conditions set forth herein, the Company hereby agrees to employ Employee in the position of Executive Vice President, CPLEX Business, having all the duties and responsibilities customarily associated with such positions, subject to modification from time to time by the Company, and Employee hereby accepts such employment by the Company. Employee's duty's shall initially include the management of the CPLEX Technology Center, and Employee shall report to the Chief Executive Officer of the Company's parent entity. With respect to any modifications of Employee's position and/or duties during the term of Employee's employment hereunder, the Company shall give due consideration to Employee's skills and experience in determining the appropriate position and duties of Employee and shall not, without Employee's consent, modify Employee's position or duties in a manner inconsistent with Employee's status as a senior executive officer of the Company; provided, however, that the foregoing shall in no way limit the ability of the Company to terminate Employee's employment at any time for any reason or for no reason. Such employment shall commence on the Effective Date and shall continue until terminated as provided in Paragraph 3 hereof. Employee shall not, without the prior written consent of Company, directly or indirectly, alone or as part of any group, association or organization, be actively engaged in or concerned with any other duties or pursuits which interfere with the performance of Employee's duties to Company or which may be contrary to the best interests of the Company. (b) Company Policies. The employment relationship between the parties shall also be governed by the general employment policies and practices of the Company now in effect or which may become effective in the future, including those relating to the protection of confidential information and trade secrets, except that when the terms of this Agreement differ from or are in conflict with the Company's general employment policies or practices, this Agreement shall control. 2 2. COMPENSATION AND BENEFITS. (a) Base Salary; Bonuses; Compensation for Part-Time Employment. As compensation for the services to be rendered by Employee during his Full-Time Employment hereunder, including all services rendered to entities affiliated with the Company, the Company agrees to pay Employee in accordance with the Company's regular payroll practices, direct salary compensation at the rate of $150,000 per year (as adjusted from time to time pursuant to the terms hereof, the "BASE SALARY"), commencing on the Effective Date. In addition, Employee shall be eligible to receive a performance bonus in the target amount of $50,000, with the actual bonus to be determined based on the achievement of performance criteria to be determined by mutual agreement of the Company and Employee (as adjusted from time to time pursuant to the terms hereof, the "BONUS"). For purposes of this Agreement, "FULL-TIME EMPLOYMENT" shall mean all periods of time during which Employee is devoting all of Employee's working time, attention and energies to performing Employee's duties to the Company. In the event Employee desires to reduce the level of Employee's time, attention or energies devoted to the Company to below Full-Time Employment levels, Employee shall give the Company sixty day's written notice of such request and the Company shall not unreasonably deny such request. Such notice shall quantify Employee's desired level of time, attention and energies to be devoted to the Company and the effective date of such reduction (any such periods of time during which such reduction are in effect, "PART-TIME EMPLOYMENT"). Employee may, subject to the consent of the Company which consent shall not be unreasonably withheld, request to resume Full-Time Employment or further adjust the level of Employee's Part-Time Employment upon sixty day's notice. During any period of Part-Time Employment, Employee's Base Salary and Bonus shall be proportionately adjusted by the Company in good faith. Such good-faith adjustments by the Company shall be conclusive and binding on Employee. (b) Employee Benefits. Employee shall be eligible to participate in the employee benefit plans and arrangements which are available or which become available, in the discretion of the Company's Board of Directors, to other employees of the Company, subject in each case to the generally applicable terms and conditions of the plan or arrangement in question and to the determination of any committee administering such plan or arrangement. The Company's presently available benefits are listed on Exhibit A hereto. Employee's benefits shall not be reduced during periods of Part-Time Employment, except that benefits that are based on levels of salary and bonus compensation, such as moneys paid during periods of paid vacation, shall be proportionately adjusted by the Company in good faith. (c) Annual Compensation Review. Employee and the Company shall review Employee's Base Salary and Bonus structure annually and may make mutually agreeable adjustments at such times. 3. TERM AND TERMINATION. (a) Term; Effect of Termination. Unless terminated by either party as provided below, this Agreement shall remain in full force and effect until the date three years after the Effective Date (such three year period, the "DEFAULT TERM") and may be extended for one annual term upon the mutual agreement of Employee and the Company (any such extension period, the "EXTENDED TERM"). Provisions of this Agreement that expressly relate to periods of time following the term of this Agreement or of Employee's employment shall survive any termination or expiration 3 of this Agreement or of Employee's employment with the Company. (b) Limitation of Liability upon Termination. If Employee's employment terminates (or is terminated) for any reason (or for no reason), Employee shall not be entitled to any payments, benefits, damages, awards or compensation other than as provided in this Agreement, or as may otherwise be available in accordance with the Company's established employee plans and policies at the time of termination. Subject to the terms and conditions hereof, Employee acknowledges that Employee's employment hereunder shall be on an at-will basis and that Company may terminate Employee's employment hereunder at any time with or without Cause. (c) Termination for Cause; Definition of "Cause". Employee's employment with the Company may be terminated for Cause at any time by the Company, upon reasonable notice to Employee of the circumstances leading to such termination for Cause. For the purpose of this Agreement, "CAUSE" shall mean (i) the substantial and continuing failure to render services to the Company or its affiliated entities in accordance with Employee's assigned duties (other than as a result of Employee's Disability, as defined below, or other medically determinable serious physical impairment), as determined by the Board of Directors of the Company's parent entity, if such failure remains uncured for a period of 30 days following delivery of notice to Employee of such failure; (ii) the conviction of a felony; (iii) gross negligence, dishonesty, breach of fiduciary duty or material breach of the terms of any confidentiality, noncompetition or other agreement in favor of the Company or its affiliated entities; (iv) the commission of an act of fraud or embezzlement which results in loss, damage or injury to the Company or its affiliated entities, whether directly or indirectly; or (v) the commission of an act which constitutes unfair competition with the Company or its affiliated entities or which induces any customer of the Company or its affiliated entities to break a contract with the Company or its affiliated entities. (d) Continuation of Option Vesting upon Certain Events. In connection with the commencement of Employee's employment with the Company, Employee has been or will be granted an option to purchase up to 200,000 shares of ILOG S.A. under its 1996 Stock Option Plan pursuant to an option agreement in substantially the form attached hereto as Exhibit B (the "OPTION"). Upon termination of Employee's employment for any reason, Employee shall have the right to exercise, within 90 days of such termination, the portion of Employee's Option that is then-exercisable pursuant to the terms and conditions of such option agreement and such option plan; provided, however, that, notwithstanding any term of such option agreement or such option plan to the contrary, if at any time prior to such time as the Option becomes fully vested and exercisable, either (X) the Company terminates Employee's employment with the Company without Employee's consent other than for Cause or (Y) Employee dies or becomes Disabled (as defined below) then, in each case, Employee's Option shall (i) continue to vest until fully vested and (ii) continue to be exercisable to the extent vested, in each case, as if Employee had remained alive, not Disabled and employed by the Company throughout the term of the Option. (e) Continuation of Salary, Bonus and Benefits upon Termination without Cause. If the Company terminates Employee's employment with the Company during the Default Term without Employee's consent other than for Cause, then, during the remaining Default Term, the Company shall continue to pay Employee the annual Base Salary and target Bonus in effect immediately prior to such termination and shall continue to provide Employee with benefits 4 substantially equivalent to those being provided immediately prior to such termination. (f) Definitions of Disability and Disabled. For purposes of this Agreement, the terms "Disabled" and "Disability" shall refer to a state of Employee's "permanent and total disability" as such term is defined in Section 22(e)(3) of the Internal Revenue Code of 1986, as amended. 4.

(b) Severability. Nothing in this Agreement shall be construed so as to require the commission of any act contrary to law and wherever there is any conflict between any provision of this Agreement and any law, statute, ordinance, order or regulation, the latter shall prevail, but in such event any provision of this Agreement shall be curtailed and limited only to the extent necessary to bring it within applicable legal requirements. If any provision of this Agreement should be held invalid or unenforceable, the remaining provisions shall be unaffected by such a holding. (c) Tax Matters. Employee has consulted Employee's own independent tax and legal advisors with respect to the transactions contemplated by this Agreement and is not relying in any respect on the Company or any officer, employee, or other agent or representative of the Company to provide any advice with respect to the federal, state, local or foreign tax consequences of the transactions contemplated hereby.
