SECTION 11. Disclosure of Information. Executive will not, either during the Term of Employment or at any time thereafter, divulge, publish, communicate, furnish or make accessible to anyone any knowledge or information with respect to the Company's confidential, secret or proprietary products, technology, methods, plans, materials and processes, or with respect to any other confidential, secret or proprietary aspects of the business, activities or products of the Company including, without limitation, (a) software programs, source code, object code, product development information, research and development projects or other technical data pertaining to the Company's products (whether or not subject to patent, trademark or copyright protection) or (b) any customer or client lists, telephone leads, prospects lists, sales figures and forecasts, purchase costs, financial projections, advertising and marketing plans and business strategies and plans; except as such items set forth in clauses (a) and (b) above may already be in the public domain through no fault of Employee (all of the foregoing items set forth in clauses (a) and (b) being referred to herein collectively as "Confidential Property"). Upon the termination of the Term of Employment, Executive shall return to the Company all property (including Confidential Property) of the Company (or any subsidiary or affiliate thereof) then in the possession of Executive and all books, records, computer tapes or discs and all other material containing non-public information concerning the business, clients or affairs of the Company or any subsidiary or affiliate thereof. 5 SECTION 12. Right to Inventions. Executive shall promptly disclose, grant and assign to the Company for its sole use and benefit any and all marks, designs, logos, inventions, improvements, technical information and suggestions relating in any way to the business conducted by the Company, which he may develop or which may be acquired by Executive during the Term of Employment (whether or not during usual working hours), together with all trademarks, patent applications, letters, patent, copyrights and reissues thereof that may at any time be granted for or upon any such mark, design, logo, invention, improvement or technical information (collectively, "Inventions"). In connection therewith, Executive shall (at the Company's sole cost and expense) take all actions reasonably necessary or desirable to assign and/or confirm the assignment of any Invention to the Company. SECTION 13. Restrictive Covenant. (a) The Company is in the business of developing, marketing, licensing and supporting network software security products and also provides consulting in network security, network design, troubleshooting and engineering (the "Business"). Executive acknowledges and recognizes that the Business has been conducted, and sales of its products have been made, throughout the United States, and Executive further acknowledges and recognizes the highly competitive nature of the industry in which the Business is involved. Accordingly, in consideration of the premises contained herein, the consideration to be received hereunder, stock options to be granted Executive, Executive shall not, during the Non-Competition Period (as defined below): (i) directly or indirectly engage, whether or not such engagement shall be as a partner, stockholder, affiliate or other participant, in any Competitive Business (as defined below), or represent in any way any Competitive Business, whether or not such engagement or representation shall be for profit, (ii) interfere with, disrupt or attempt to disrupt the relationship, contractual or otherwise, between the Company and any other person or entity, including, without limitation, any customer, supplier, employee or consultant of the Company, (iii) induce any employee of the Company to terminate his employment with the Company or to engage in any Competitive Business in any manner described in the foregoing clause (i) (as well as an officer or director of any Competitive Business), or (iv) affirmatively assist or induce any other person or entity to engage in any Competitive Business in any manner described in the foregoing clause (i) (as well as an officer or director of any Competitive Business). Anything contained in this Section 13 to the contrary notwithstanding, an investment by Executive in any publicly traded company in which Executive and his affiliates exercise no operational or strategic 6 control and which constitutes less than 5% of the capital of such entity shall not constitute a breach of this Section 13. (b) As used herein, "Non-Competition Period" shall mean the period commencing on the date hereof and terminating on the Termination Date; provided, however, that if the Term of Employment shall have been terminated pursuant to Section 8 (a), then "Non-Competition Period" shall mean the period commencing on the date hereof and ending on the second anniversary of the Termination Date. "Competitive Business" shall mean any business in any State of the United States engaged in the development, marketing and licensing of network software security products, or in any other line of business in which the Company was engaged or had a formal plan to enter as of the Termination Date. (c) Executive understands that the foregoing restrictions may limit his ability to earn a livelihood in a business similar to the business of the Company, but he nevertheless believes that he has received and will receive sufficient consideration and other benefits as an employee of the Company and as otherwise provided hereunder and pursuant to other agreements between the Company and Executive to justify clearly such restrictions which, in any event (given his education, skills and ability), Executive does not believe would prevent him from earning a living. SECTION 14. Enforcement; Severability; Etc. It is the desire and intent of the parties that the provisions of this Agreement shall be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated to be invalid or unenforceable, such provision shall be deemed amended to (a) delete therefrom the portion thus adjudicated to be invalid or unenforceable, such deletion to apply only with respect to the operation of such provision in the particular jurisdiction in which such adjudication is made or (b) otherwise to render it enforceable in such jurisdiction.

In the event of a breach or threatened breach by Executive of the provisions of this Agreement, the Company shall be entitled to an injunction restraining him from such breach. Nothing contained in this Agreement shall be construed as prohibiting the Company from or 7 limiting the Company in pursuing any other remedies available for any breach or threatened breach of this Agreement.

(a) The purchase rights represented by this Option may be exercised by the Holder hereof, in whole or in part (but not as to less than a whole Common Share), as to the vested portion (as defined below) of this Option only, at any time, and from time to time, during the period commencing this date, until May __, 2003 (the "Expiration Date"), by the presentation of this Option, with the purchase form attached duly executed, at the Company's office (or such office or agency of the Company as it may designate in writing to the Holder hereof by notice pursuant to Section 13 hereof), specifying the number of Common Shares as to which the Option is being exercised, and upon payment by the Holder to the Company in cash or by certified check or bank draft, in an amount 2 equal to the Option Price times the number of Common Shares then being purchased hereunder. This Option shall vest as follows: (i) As to 34% of the Underlying Shares on the date of this Option; (ii) As to the balance of 66% of the Underlying Shares, 22% of such shares on each of the first three anniversary dates of the date of this Option, provided the Optionee is then an employee of the Company; (iii) As to 50% of the remaining Underlying Shares if a Change in Control occurs within one year of the date of this Option, provided the Optionee is then an employee of the Company; (iv) As to all of the unvested portion of this Option if a Change of Control occurs more than one year after the date of this Option, provided the Optionee is then an employee of the Company.

(b) The Company agrees that the Holder hereof shall be deemed the record owner of such Underlying Securities as of the close of business on the date on which this Option shall have been presented and payment made for such Underlying Securities as aforesaid. Certificates for the Underlying Securities so obtained shall be delivered to the Holder hereof within a reasonable time, not exceeding seven (7) days, after the rights represented by this Option shall have been so exercised. If this Option shall be exercised in part only or transferred in part subject to the provisions herein, the Company shall, upon surrender of this Option for cancellation or partial transfer, deliver a new Option evidencing the rights of the Holder hereof to purchase the balance of the Underlying Shares which such Holder is entitled to purchase hereunder. 3. Subject to the provisions of Section 8 hereof, (i) this Option is exchangeable at the option of the Holder at the aforesaid office of the Company for other Options of different denominations entitling the Holder thereof to purchase in the aggregate the same number of Common Shares as are purchasable hereunder; and (ii) this Option may be divided or combined with other Options which carry the same rights, in either case, upon presentation hereof at the aforesaid office of the Company together with a written notice, signed by the Holder hereof, specifying the names and denominations in which new Options are to be issued, and the payment of any transfer tax due in connection therewith. 3 4. Subject and pursuant to the provisions of this Section 4, the Option Price and number of Common Shares subject to this Option shall be subject to adjustment from time to time as set forth hereinafter in this Section 4. (a) If the Company shall at any time subdivide its outstanding Common Shares by recapitalization, reclassification, stock dividend, or split-up thereof or other means, the number of Common Shares subject to this Option immediately prior to such subdivision shall be proportionately increased and the Option Price shall be proportionately decreased, and if the Company shall at any time combine the outstanding Common Shares by recapitalization, reclassification or combination thereof or other means, the number of Common Shares subject to this Option immediately prior to such combination shall be proportionately decreased and the Option Price shall be proportionately increased. Any such adjustment to the Option Price shall become effective at the close of business on the record date for such subdivision or combination. (b) If the Company after the date hereof shall distribute to all of the holders of its Common Shares any securities including, but not limited to Common Shares, or other assets (other than a cash distribution made as a dividend payable out of earnings or out of any earned surplus legally available for dividends under the laws of the jurisdiction of incorporation of the Company), the Board of Directors shall be required to make such equitable adjustment in the Option Price and the type and/or number of Underlying Securities in effect immediately prior to the record date of such distribution as may be necessary to preserve to the Holder of this Option rights substantially proportionate to and economically equivalent to those enjoyed hereunder by such Holder immediately prior to the happening of such distribution. Any such adjustment made reasonably and in good faith by the Board of Directors shall be final and binding upon the Holders and shall become effective as of the record date for such distribution. (c) No adjustment in the number of Common Shares subject to this Option or the Option Price shall be required under this Section 4 unless such adjustment would require an increase or decrease in such number of shares of at least 1% of the then adjusted number of Common Shares issuable upon exercise of the Option, provided, however, that any adjustments which by reason of the foregoing are not required at the time to be made shall be carried forward and taken into account and included in determining the amount of any subsequent adjustment. If the Company shall make a record of the Holders of its Common Shares for the purpose of entitling them to receive any dividend or distribution and legally abandon its plan to pay or deliver such dividend or distribution then no adjustment in the number of Common Shares subject to the Option shall be required by reason of the making of such record. 4 (d) In case of any capital reorganization or reclassification or change of the outstanding Common Shares (exclusive of a change covered by Section 4(a) hereof or which solely affects the par value of such Common Shares) or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification, change, capital reorganization or change in the ownership of the outstanding Common Shares), or in the case of any sale or conveyance or transfer of all or substantially all of the assets of the Company and in connection with which the Company is dissolved, the Holder of this Option shall have the right thereafter (until the expiration of the right of exercise of this Option) to receive upon the exercise hereof, for the same aggregate Option Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property receivable upon such reclassification, change, capital reorganization, merger or consolidation, or upon the dissolution following any sale or other transfer, by a holder of the number of Common Shares of the Company equal to the number of common shares obtainable upon exercise of this Option immediately prior to such event; and if any reorganization, reclassification, change, merger, consolidation, sale or transfer also results in a change in Common Shares covered by Section 4(a), then such adjustment shall be made pursuant to both this Section 4(d) and Section 4(a). The provisions of this Section 4(d) shall similarly apply to successive reclassification, or capital reorganizations, mergers or consolidations, changes, sales or other transfers. (e) The Company shall not be required to issue fractional Common Shares upon any exercise of this Option. As to any final fraction of a Common Share which the Holder of this Option would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to the same fraction of the "current market price" (as defined in Section 4(f) below) of a share of such stock on the business day preceding the day of exercise. The Holder of this Option, by his acceptance hereof, expressly waives any right to receive any fractional shares of stock upon exercise of this Option. (f) As used herein, the "current market price" per share of Common Stock on any date shall be: (i) if the Common Stock is listed or admitted for trading on any national securities exchange, the last reported sales price as reported on such national securities exchange; (ii) if the Common Stock is not listed or admitted for trading on any national securities exchange, the average of the last reported closing bid and asked quotation for the Common Stock as reported on the Automated Quotation System of NASDAQ or a similar service if NASDAQ is not reporting such information; (iii) if the Common Stock is not listed or admitted for trading on any national securities exchange or quoted by NASDAQ 5 or a similar service, the average of the last reported bid and asked quotation for the Common Stock as quoted by a market maker in the Common Stock (or if there is more than one market maker, the bid and asked quotation shall be obtained from two market makers and the average of the lowest bid and highest asked quotation shall be the "current market price"); or (iv) if the Common Stock is not listed or admitted for trading on any national securities exchange or quoted by NASDAQ and there is no market maker in the Common Stock, the fair market value of such shares as determined by the Board of Directors. (g) Irrespective of any adjustments pursuant to this Section 4 in the Option Price or in the number, or kind, or class of shares or other securities or other property obtainable upon exercise of this Option, and without impairing any such adjustment the certificate representing this Option may continue to express the Option Price and the number of Common Shares obtainable upon exercise at the same price and number of Common Shares as are stated herein. (h) Until this Option is exercised, the Underlying Shares, and the Option Price shall be determined exclusively pursuant to the provisions hereof. (i) Upon any adjustment of this Option the Company shall give written notice thereof to the Holder which notice shall include the number of Underlying Securities purchasable and the price per share upon exercise of this Option and shall set forth in reasonable detail the events which resulted in such adjustment 5. For the purposes of this Option, the terms "Common Shares" or "Common Stock" shall mean (i) the class of stock designated as the common stock of the Company on the date set forth on the first page hereof or (ii) any other class of stock resulting from successive changes or reclassification of such Common Stock consisting solely of changes from par value to no par value, or from no par value to par value or changes in par value. If at any time, as a result of an adjustment made pursuant to Section 4, the securities or other property obtainable upon exercise of this Option shall include shares or other securities of another corporation or other property, then thereafter, the number of such other shares or other securities or property so obtainable shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Shares contained in Section 4, and all other provisions of this Option with respect to Common Shares shall apply on like terms to any such other shares or other securities or property. Subject to the foregoing, and unless the context requires otherwise, all references herein to Common Shares shall, in the event of an adjustment pursuant to Section 4, be deemed to refer also to any other shares or other securities or property when obtainable as a result of such adjustments. 6 6. The Company covenants and agrees that: (a) During the period within which the rights represented by this Option may be exercised, the Company shall, at all times, reserve and keep available out of its authorized capital stock, solely for the purposes of issuance upon exercise of this Option, such number of its Common Shares as shall be issuable upon the exercise of this Option and at its expense will obtain the listing thereof on all quotation systems or national securities exchanges on which the Common Shares are then listed; and if at any time the number of authorized Common Shares shall not be sufficient to effect the exercise of this Option, the Company will take such corporate action as may be necessary to increase its authorized but unissued Common Shares to such number of shares as shall be sufficient for such purpose; the Company shall have analogous obligations with respect to any other securities or property issuable upon exercise of this Option; (b) All Common Shares which may be issued upon exercise of the rights represented by this Option will, upon issuance, be validly issued, fully paid, non-assessable and free from all taxes, liens and charges with respect to the issuance thereof; and (c) All original issue taxes payable in respect of the issuance of Common Shares upon the exercise of the rights represented by this Option shall be borne by the Company, but in no event shall the Company be responsible or liable for income taxes or transfer taxes upon the transfer of any Options. 7. Until exercised, this Option shall not entitle the Holder hereof to any voting rights or other rights as a shareholder of the Company. 8. This Option may not be transferred, sold or assigned except to, in whole or in part (i) any entity controlled by, or under common control with, the Optionee, (ii) the spouse, lineal descendants, estate or a trust for the benefit of any of the foregoing, or (iii) by operation of law. No transfer of all or a portion of the Option (as permitted hereby) or the Underlying Securities shall be made at any time unless the Company shall have been supplied with evidence reasonably satisfactory to it that such transfer is not in violation of the Securities Act of 1933, as amended (the "Act"). Subject to the satisfaction of the aforesaid condition and upon surrender of this Option or certificates for any Underlying Securities at the office of the Company, the Company shall deliver a new Option or Options or new certificate or certificates for Underlying Securities to and in the name of the permitted assignee or assignees named therein.
