The term “Substantial Breach” means (i) the failure by the Company to pay to the Executive the Salary and Bonus, if any, in accordance with Sections 3(a) and 3(b) hereof; (ii) the failure by the Company to allow the Executive to participate in the Company’s employee benefit plans generally available from time to time to senior executives of the Company; (iii) the failure of any successor to all or substantially all of the business and/or assets of the Company to assume this Agreement; provided, however, that the term “Substantial Breach” shall not include a termination of the Executive’s employment hereunder pursuant to Sections 6(b) or (c) hereof; (iv) the substantial and material diminution in the Executive’s duties, responsibilities, reporting relationship or position; (v) a greater than fifteen percent reduction of the Salary; or (vi) the Company’s requiring the Executive to relocate his principal location of employment to any place outside of a 50 mile driving distance of the Executive’s current work site, without the consent of the Executive.

(f) Payments. In the event that the Executive’s employment terminates for any reason, including expiration of the Term by reason of nonrenewal as provided in Section 2 hereof, the Company shall pay to the Executive all amounts accrued but unpaid hereunder through the date of termination in respect of Salary or unreimbursed expenses. In the event the Executive’s employment is terminated by the Company without Cause (other

4

than an election not to renew the Employment Term pursuant to Section 2 hereof), or by the Executive with Good Reason, in addition to the amounts specified in the foregoing sentence, (i) the Executive shall continue to receive the Salary (less any applicable withholding or similar taxes) at the rate in effect hereunder on the date of such termination periodically, in accordance with the Company’s prevailing payroll practices, for a period of twelve months following the date of such termination (the “Severance Term”), (ii) to the extent permissible under the Company’s health plans, the Executive shall continue to receive any health benefits on the same basis as such health benefits were provided to such Executive as of the date of such termination in accordance with Section 3(c) hereof during the Severance Term; and (iii) any unexercised options which were fully vested as of the date of the Executive’s termination shall remain exercisable through the expiration of the Severance Term, notwithstanding any contrary provisions of the Aelita Software Corporation Omnibus Stock Option Plan or any agreement under which options have been granted to the Executive.

(g) Survival of Operative Sections. Upon any termination of the Executive’s employment, the provisions of Sections 6(f) and 7 through 18 of this Agreement shall survive to the extent necessary to give effect to the provisions thereof.

Section 7. Secrecy and Non-Competition.

(a) No Competing Employment. The Executive acknowledges that the agreements and covenants contained in this Section 7 are essential to protect the value of the Company’s business and assets and by his current employment with the Company and its subsidiaries, the Executive has obtained and will obtain such knowledge, contacts, know-how, training and experience and there is a substantial probability that such knowledge, know-how, contacts, training and experience could be used to the substantial advantage of a competitor of the Company and to the Company’s substantial detriment. Therefore, the Executive agrees that for the period commencing on the date of this Agreement and ending on the first anniversary of the termination of the Executive’s employment hereunder (such period is hereinafter referred to as the “Restricted Period”) with respect to any State in which the Company is engaged in business during the Employment Term, the Executive shall not participate or engage, directly or indirectly, for himself or on behalf of or in conjunction with any person, partnership, corporation or other entity, whether as an employee, agent, officer, director, shareholder, partner, joint venturer, investor or otherwise, in any business activities if such activities consist of any activities undertaken or expressly contemplated to be undertaken by the Company or any of its subsidiaries or by the Executive at any time during the Employment Term.

(b) Nondisclosure of Confidential Information. The Executive, except in connection with his employment hereunder, shall not disclose to any person or entity or use, either during the Employment Term or at any time thereafter, any information not in the public domain or generally known in the industry, in any form, acquired by the Executive while employed by the Company or any predecessor to the Company’s business or, if acquired following the Employment Term, such information which, to the Executive’s knowledge, has been acquired, directly or indirectly, from any person or entity owing a duty of confidentiality to the Company or any of its subsidiaries or affiliates, relating to the Company, its subsidiaries or affiliates, including but not limited to information regarding customers, vendors, suppliers, trade secrets, training programs, manuals or materials, technical information, contracts, systems, procedures, mailing lists, know-how, trade names, improvements, price lists, financial or other data (including the revenues, costs or profits associated with any of the Company’s products or services), business plans, code books, invoices and other financial statements, computer programs, software systems, databases, discs and printouts, plans (business, technical or otherwise), customer and industry lists, correspondence, internal reports, personnel files, sales and advertising material, telephone numbers, names, addresses or any other compilation of information, written or unwritten, which is or was used in the business of the Company or any subsidiaries or affiliates thereof. The Executive agrees and acknowledges that all of such information, in any form, and copies and extracts thereof, are and shall remain the sole and exclusive property of the Company, and upon termination of his employment with the Company, the Executive shall return to the Company the originals and all copies of any such information provided to or acquired by the Executive in connection with the performance of his duties for the Company, and shall return to the Company all files, correspondence and/or other communications received, maintained and/or originated by the Executive during the course of his employment.

(c) No Interference. During the Restricted Period, the Executive shall not, whether for his own account or for the account of any other individual, partnership, firm, corporation or other business organization (other than the Company), directly or indirectly solicit, endeavor to entice away from the Company or its subsidiaries, or otherwise directly interfere with the relationship of the Company or its subsidiaries with any person who, to the knowledge of the Executive, is employed by or otherwise engaged to perform services for the Company or its subsidiaries (including, but not limited to, any independent sales representatives or organizations) or who is, or was within the then most recent twelve-month period, a customer or client, of the Company, its predecessors or any of its subsidiaries. The placement of any general classified or “help wanted” advertisements and/or general solicitations to the public at large shall not constitute a violation of this Section 7(c) unless the Executive’s name is contained in such advertisements or solicitations.

6

(d) Inventions, etc. The Executive hereby sells, transfers and assigns to the Company or to any person or entity designated by the Company all of the entire right, title and interest of the Executive in and to all inventions, ideas, disclosures and improvements, whether patented or unpatented, and copyrightable material, made or conceived by the Executive, solely or jointly, during his employment by the Company which relate to methods, apparatus, designs, products, processes or devices, sold, leased, used or under consideration or development by the Company, or which otherwise relate to or pertain to the business, functions or operations of the Company or which arise from the efforts of the Executive during the course of his employment for the Company. The Executive shall communicate promptly and disclose to the Company, in such form as the Company requests, all information, details and data pertaining to the aforementioned inventions, ideas, disclosures and improvements; and the Executive shall execute and deliver to the Company such formal transfers and assignments and such other papers and documents as may be necessary or required of the Executive to permit the Company or any person or entity designated by the Company to file and prosecute the patent applications and, as to copyrightable material, to obtain copyright thereof. Any invention relating to the business of the Company and disclosed by the Executive within one year following the termination of his employment with the Company shall be deemed to fall within the provisions of this paragraph unless proved to have been first conceived and made following such termination.

Section 8. Injunctive Relief. Without intending to limit the remedies available to the Company, the Executive acknowledges that a breach of any of the covenants contained in Section 7 hereof may result in material irreparable injury to the Company or its subsidiaries or affiliates for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat thereof, the Company shall be entitled to obtain a temporary restraining order and/or a preliminary or permanent injunction, without the necessity of proving irreparable harm or injury as a result of such breach or threatened breach of Section 7 hereof, restraining the Executive from engaging in activities prohibited by Section 7 hereof or such other relief as may be required specifically to enforce any of the covenants in Section 7 hereof.

Section 9. Extension of Restricted Period.
