(a) Number of Option Shares. Each Option Document shall state the number of Shares to which it pertains. An Optionee may receive more than one Option, which may include options which are intended to be ISOs and Options which are not intended to be ISOs, but only on the terms and subject to the conditions and restrictions of the Plan. (b) Option Price. Each Option Document shall state the Option Price which, for all ISOs, shall be at least 7 100% of the Fair Market Value of the Shares at the time the Option is granted as determined by the Committee in accordance with this subsection 8(b); provided, however, that if an ISO is granted to an Optionee who then owns, directly or by attribution under section 424(d) of the Code, shares possessing more than 10% of the total combined voting power of all classes of stock of the Company or an Affiliate, then the Option Price shall be at least 110% of the Fair Market Value of the Shares at the time the option is granted. If the Common Stock is traded in a public market, then the Fair Market Value per share shall be, if the Shares are listed on a national securities exchange or included in the NASDAQ National Market System, the last reported sale price thereof on the relevant date, or, if the Shares are not so listed or included, the mean between the last reported "bid" and "asked" prices thereof, as reported on NASDAQ or, if not so reported, as reported by the National Daily Quotation Bureau, Inc., or as reported in a customary financial reporting service, as applicable and as the Committee determines, on the relevant date. If the Common Stock is not traded in a public market on the relevant date, the Fair Market Value shall be as determined in good faith by the Committee. (c) Exercise. No Option shall be deemed to have been exercised prior to the receipt by the Company of written notice of such exercise and of payment in full of the Option Price for the Shares to be purchased. Each such notice shall specify the number of Shares to be purchased and shall (unless the Shares are covered by a then current registration statement 8 or a Notification under Regulation A under the Securities Act of 1933, as amended (the "Act")), contain the Optionee's acknowledgment in form and substance satisfactory to the Company that (i) such Shares are being purchased for investment and not for distribution or resale (other than a distribution or resale which, in the opinion of counsel satisfactory to the Company, may be made without violating the registration provisions of the Act), (ii) the Optionee has been advised and understands that (A) the Shares have not been registered under the Act and are "restricted securities" within the meaning of Rule 144 under the Act, and are subject to restrictions on transfer and (B) the Company is under no obligation to register the Shares under the Act or to take any action which would make available to the Optionee any exemption from such registration, (iii) such Shares may not be transferred without compliance with all applicable federal and state securities laws, and (iv) an appropriate legend referring to the foregoing restrictions on transfer and any other restrictions imposed under the Option Documents may be endorsed on the certificates. Notwithstanding the foregoing, if the Company determines that issuance of Shares should be delayed pending (i) registration under federal or state securities laws, (ii) the receipt of an opinion that an appropriate exemption from such registration is available, (iii) the listing or inclusion of the Shares on any securities exchange or in an automated quotation system or (iv) the consent or approval of any governmental regulatory body whose consent or approval is necessary in connection with the issuance of such Shares, the 9 Company may defer exercise of any Option granted hereunder until any of the events described in this subsection 8(c) has occurred. (d) Medium of Payment. An Optionee shall pay for Shares (i) in cash, (ii) by certified check payable to the order of the Company, or (iii) by such other mode of payment as the Committee may approve, including payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board. Furthermore, the Committee may provide in an Option Document that payment may be made in whole or in part in shares of the Company's Common Stock held by the Optionee for at least six months. If payment is made in whole or in part in shares of the Company's Common Stock, then the Optionee shall deliver to the Company certificates registered in the name of such Optionee representing the shares owned by such Optionee, free of all liens, claims and encumbrances of every kind and having an aggregate Fair Market Value on the date of delivery that is at least as great as the Option Price of the Shares (or relevant portion thereof) with respect to which such Option to be exercised by the payment in shares of Common Stock, accompanied by stock powers duly endorsed in blank by the Optionee. Notwithstanding the foregoing, the Committee may impose from time to time such limitations and prohibitions on the use of shares of the Common Stock to exercise an Option as it deems appropriate. (e) Termination of Options. (i) No Option shall be exercisable after the first to occur of the following: 10 (A) Expiration of the Option term specified in the Option Document, which for an ISO shall not exceed (1) ten years from the date of grant, or (2) five years from the date of grant if the Optionee on the date of grant owns, directly or by attribution under section 424(d) of the Code, shares possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of an Affiliate; (B) The date the Optionee's employment or service with the Company or its Affiliates terminates for any reason other than Disability or death or as otherwise specified in subsection 8(e)(i)(D) or Section 9 below; (C) Expiration of one year from the date the Optionee's employment or service with the Company or its Affiliates terminates due to the Optionee's Disability or death; (D) A finding by the Committee, after full consideration of the facts presented on behalf of both the Company and the Optionee, that the Optionee has breached his employment or Service contract with the Company or an Affiliate, or has been engaged in any sort of disloyalty to the Company or an Affiliate, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty in the course of his employment or Service, or has disclosed trade secrets or confidential information of the Company or an Affiliate. In such event, in addition to immediate termination of the Option, the Optionee shall automatically forfeit all Shares for which the Company has not yet delivered the share certificates upon refund 11 by the Company of the Option Price of such Shares. Notwithstanding anything herein to the contrary, the Company may withhold delivery of share certificates pending the resolution of any inquiry that could lead to a finding resulting in a forfeiture; or (E) The date, if any, set by the Board of Directors as an accelerated expiration date pursuant to Section 9 hereof. (ii) Notwithstanding the foregoing, the Committee may extend the period during which an Option may be exercised to a date no later than the date of the expiration of the Option term specified in the Option Documents, as they may be amended, provided that any change pursuant to this subsection 8(e)(ii) that would cause an ISO to become a Non-qualified Stock Option may be made only with the consent of the Optionee. (A) Transfers. No Option granted under the Plan may be transferred, except by will or by the laws of descent and distribution. During the lifetime of the person to whom an Option is granted, such Option may be exercised only by him. Notwithstanding the foregoing, Non-qualified Stock Option may be transferred pursuant to the terms of a "qualified domestic relations order," within the meaning of sections 401(a)(13) and 414(p) of the Code or within the meaning of Title I of the Employee Retirement Income Security Act of 1974, as amended. (B) Holding Period. No Option granted under the Plan may be exercised unless such period of time as may 12 be specified in the Option Documents has elapsed from the date of grant. (C) Limitation on ISO Grants. No ISO shall be granted if, for any calendar year during which such ISO may be exercised, the Fair Market Value of the Shares (determined at the time the ISO is granted) with respect to which such ISO is exercisable for the first time by the Optionee, plus the aggregate Fair Market Value (determined at such time) of any Shares with respect to which any other incentive stock option of the Company or its Affiliates are exercisable for the first time by the Optionee, exceeds $100,000. (D) Other Provisions. The Option Documents shall contain such other provisions including, without limitation, provisions authorizing the Committee to accelerate the exercisability of all or any portion of an Option granted pursuant to the Plan, additional restrictions upon the exercise of the Option or additional limitations upon the term of the Option, as the Committee shall deem advisable. (E) Amendment. The Committee shall have the right to amend Option Documents issued to an Optionee, subject to the Optionee's consent if such amendment is not favorable to the Optionee, except that the consent of the Optionee shall not be required for any amendment made under Section 9 of the Plan. 9. Change of Control. In the event of a Change of Control, the Committee may take whatever action with respect to the Options outstanding it deems necessary or desirable, 13 including, without limitation, accelerating the expiration or termination date or the date of exercisability in the respective Option Documents. A "Change of Control" shall be deemed to have occurred upon the earliest to occur of the following events: (i) the date the shareholders of the Company (or the Board of Directors, if shareholder action is not required) approve a plan or other arrangement pursuant to which the Company will be dissolved or liquidated, or (ii) the date the shareholders of the Company (or the Board of Directors, if shareholder action is not required) approve a definitive agreement to sell or otherwise dispose of substantially all of the assets of the Company, or (iii) the date the shareholders of the Company (or the Board of Directors, if shareholder action is not required) and the shareholders of the other constituent corporation (or its board of directors if shareholder action is not required) have approved a definitive agreement to merge or consolidate the Company with or into such other corporation, other than, in either case, a merger or consolidation of the Company in which holders of shares of the Company's Common Stock or other common voting stock immediately prior to the merger or consolidation will hold at least a majority of the ownership of common stock of the surviving corporation (and, if one class of common stock is not the only class of voting securities entitled to vote on the election of directors of the surviving corporation, a majority of the voting power of the surviving corporation's voting securities) immediately after the merger or consolidation, which 14 common stock (and if applicable voting securities) is to be held in the same proportion as such holders, ownership of Common Stock or other common voting stock of the Company immediately before the merger or consolidation, or (iv) the date any entity, person or group (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Securities Exchange Act of 1934, as amended) other than the Company or any of its subsidiaries, or any employee benefit plan (or related trust) sponsored or maintained by the Company or any of its subsidiaries, shall have become the beneficial owner of, or shall have obtained voting control over, outstanding shares of the Company's voting stock representing more than fifty percent (50%) of the voting power of all of the Company's outstanding voting stock. 10.

The Committee shall have authority to determine the adjustments to be made under this Section, and 15 any such determination by the Committee shall be final, binding and conclusive; provided, however, that no adjustment shall be made which will cause an ISO to lose its status as such without the consent of the Optionee, except for adjustments made pursuant to Section 9 hereof. 11.

Nevertheless, the Board of Directors of the Company may not: (i) change the class of individuals eligible to receive an ISO, (ii) increase the maximum number of Shares as to which Options may be granted, or (iii) make any other change or amendment as to which shareholder approval is required in order to satisfy the conditions set forth in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, in each case without obtaining approval, within twelve months before or after such action, by vote of a majority of the votes cast at a duly called meeting of the shareholders at which a quorum representing a majority of all outstanding voting stock of the Company is, either in person or by proxy, present and voting on the matter. No amendment to the Plan shall adversely affect any outstanding Option, however, without the consent of the Optionee. 12. No Commitment to Retain. The grant of an Option pursuant to the Plan shall not be construed to imply or to constitute evidence of any agreement, express or implied, on the part of the Company or any Affiliate to retain the Optionee in 16 the employ of the Company or an Affiliate and/or as a member of the Company's Board of Directors or in any other capacity. 13. Withholding of Taxes.
