Subject to the other provisions of the Plan, a Participant may receive ISOs and NSOs at the same time, provided that the ISOs and NSOs are clearly designated as such, and the exercise of one does not affect the exercise of the other. Except as otherwise expressly provided herein, all of the provisions and requirements of the Plan relating to Stock Options shall apply to ISOs and NSOs. III. ADMINISTRATION The Plan shall be administered by the Board of Directors (the "Board") of the Company or by a committee of two or more directors ("Committee") appointed by the Board, each of whom shall be a "non-employee director" as defined in Rule 16b-3 under the Securities Exchange Act of 1934,as amended (the "Exchange Act"). The Committee or the Board of Directors, as the case may be,shall have full authority to administer the Plan, including authority tointerpret and construe any provision of the Plan and any Stock Options granted thereunder, and to adopt such rules and regulations for administering the Plan as it may deem necessary in order to comply with the requirements of the Code or in order that Stock Options that are intended to be ISOs will be classified as incentive stock options under the Code, or in order to conform to any regulation or to any change in any law or regulation applicable thereto. All actions taken and all interpretations and determinations made by the Board or Committee in good faith (including determinations of Fair Market Value) shall be final and binding upon all Participants, the Company and all other interested persons. No member of the Board or Committee shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan, and all members of the Board and Committee shall, in addition to their rights as directors, be fully protected by the Company with respect to any such action, determination or interpretation.

IV. DEFINITIONS 4.1 "STOCK OPTION." A Stock Option is the right granted under the Plan to an Employee, director, or consultant to purchase at such time or times, on such terms and at such price or prices ("Option Price") as are determined by the Board or Committee, the number of shares of Common Stock determined by the Board or Committee. 4.2 "COMMON STOCK." A share of Common Stock means a share of authorized but unissued or reacquired common stock of the Company. 4.3 "FAIR MARKET VALUE." If the Common Stock is traded publicly, the Fair Market Value of a share of Common Stock on any date shall be the average of the representative closing bid and asked prices, as quoted by the National Association of Securities Dealers through NASDAQ (its automated system for reporting quotes), for the date in question, or, if the Common Stock is -2- listed on the NASDAQ National Market System or is listed on a national stock exchange, the officially quoted closing price on NASDAQ or such exchange, as the case may be, on the date in question. If the Common Stock is not traded publicly, the Fair Market Value of a share of Common Stock on any date shall be determined in good faith by the Board of Directors or the Committee after such consultations with outside legal, accounting and other experts as the Board of Directors or the Committee may deem advisable. 4.4 "EMPLOYEE." An Employee is an employee of the Company or any Participating Subsidiary. 4.5 "PARTICIPANT." A Participant is an Employee, director or consultant to whom a Stock Option is granted. V. ELIGIBILITY AND PARTICIPATION Grants of ISOs and NSOs may be made to Employees of the Company or any Participating Subsidiary. Grants of NSOs may be made to Employees of, directors of or consultants to the Company or any Participating Subsidiary. Any director of the Company or of a Participating Subsidiary who is also an Employee shall also be eligible to receive ISOs. The Board or Committee shall from time to time determine the Participants to whom Stock Options shall be granted, the type of Stock Option granted, the number of shares of Common Stock subject to each Stock Option to be granted to each such Participant, the Option Price of such Stock Option, and all other terms and conditions of the Stock Option, all as provided in the Plan. The Option Price of any ISO shall be not less than the Fair Market Value of a share of Common Stock on the date on which the Stock Option is granted, and the Option Price of an NSO may not be less than 85% of the Fair Market Value on the date the NSO is granted. If an ISO is granted to an Employee who then owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company, the Option Price of such ISO shall be at least 110% of the Fair Market Value of the Common Stock subject to the ISO at the time such ISO is granted, and such ISO shall not be exercisable after five years after the date on which it was granted. Each Stock Option shall be evidenced by a written agreement ("Option Agreement") containing such terms and provisions as the Board or Committee may determine, subject to the provisions of the Plan. -3- VI. SHARES OF COMMON STOCK SUBJECT TO THE PLAN 6.1 MAXIMUM NUMBER. Subject to adjustment as provided in Section 6.2 below, the maximum aggregate number of shares of Common Stock that may be made subject to Stock Options shall be 800,000 shares of Common Stock. Such shares may either be authorized but unissued or treasury shares of the Company. The aggregate Fair Market Value (determined as of the time the ISO is granted) of the stock as to all ISOs granted to an individual which may first become exercisable in a particular calendar year may not exceed $100,000. If any shares of Common Stock subject to Stock Options are not purchased or otherwise paid for before such Stock Options expire, such shares may again be made subject to Stock Options. 6.2 ADJUSTMENTS. In the event the outstanding shares of Common Stock of the Company are increased, decreased, changed into or exchanged for a different number or kind of securities of the Company, through reorganization, recapitalization, reclassification, stock dividend, stock split, or other change in corporate structure, an appropriate and proportionate adjustment shall be made in the numbers, kinds, and prices of the Stock Options granted under the Plan (but not in the aggregate purchase price), and in the total number of shares of Common Stock with respect to which Stock Options may be granted hereunder. If any adjustment shall result in a fractional share, the fraction shall be disregarded, and the Company shall have no obligation to make any cash or other payment with respect to such a fractional share. Any adjustment shall be made by the Board, whose determination in that respect, and as to whether any adjustment needs to be made, shall be final, binding and conclusive. VII. EXERCISE OF STOCK OPTIONS 7.1 TIME OF EXERCISE. Subject to the provisions of the Plan, the Board or Committee, in its discretion, shall determine the time when a Stock Option, or a portion of a Stock Option, shall become exercisable, and the time when a Stock Option, or a portion of a Stock Option, shall expire. Such time or times shall be set forth in the Option Agreement evidencing such Stock Options. A Stock Option shall expire, to the extent not exercised, no later than the tenth anniversary of the date on which it was granted. The Board or Committee may accelerate the vesting of any Participant's Stock Option by giving written notice to the Participant and, with the consent of the holder thereof, modify, amend or terminate any Stock Option. Upon receipt of such notice, the Participant and the Company shall amend the Option Agreement to reflect the new vesting schedule. -4- The acceleration of the exercise period of a Stock Option shall not affect the expiration date of that Stock Option. 7.2 EXCHANGE OF OUTSTANDING STOCK. The Board or Committee, in its sole discretion, may permit a Participant to surrender to the Company shares of the Common Stock previously acquired by the Participant as part or full payment for the exercise of a Stock Option. Such surrendered shares shall be valued at their Fair Market Value on the date of exercise. 7.3 PAYMENT. The exercise price shall be paid in full at the time of exercise of the Stock Options in cash or in such other form of lawful consideration as the Board of Directors or the Committee may approve from time to time, including, without limitation, the transfer of outstanding shares of Common Stock as provided in Section 7.2. 7.4 TERMINATION OF EMPLOYMENT BEFORE EXERCISE. If the employment of a Participant who was an Employee of the Company or a Participating Subsidiary when the Stock Option was granted shall terminate for any reason other than the Participant's death or disability, any Stock Options then held by the Participant, to the extent then exercisable under the applicable Option Agreement(s), shall remain exercisable after the termination of his employment for a period of three months (but not later than the specified expiration date). If the Participant's employment is terminated because the Participant is disabled within the meaning of Section 22(e)(3) of the Code, any Stock Option then held by the Participant, to the extent then exercisable under the applicable Option Agreement(s), shall remain exercisable after the termination of his employment for a period of twelve months (but not later than the specified expiration date). If the Participant dies while employed by the Company or a Participating Subsidiary, or during the three-month or twelve-month periods referred to above, his Stock Options may be exercised to the extent that they were exercisable on the date of cessation of his employment by his estate, or duly appointed representative, or beneficiary who acquires the Stock Options by will or by the laws of descent and distribution, and each of his Stock Options shall terminate on the first anniversary of the date of his death (but not later than the specified expiration dates). To the extent a Stock Option either (i) has not yet become exercisable on termination of employment (I.E., not vested) or (ii) is exercisable on such termination but is not exercised during the applicable period, it shall be deemed to have been forfeited and of no further force or effect. Notwithstanding anything in this Section 7.4 to the contrary, the Board or Committee may, in its sole discretion, provide (whether by initial grant or subsequent modification or amendment with the consent of the holder thereof) other and different provisions with respect to termination, expiration and exercisability for NSOs in the event of termination of employment, engagement or term, as the case may be, death or disability of any Employee, consultant or director (such provisions shall be set forth in the Stock Option Agreements evidencing such NSOs). -5- 7.5 DISPOSITION OF FORFEITED STOCK OPTIONS. Any shares of Common Stock subject to Stock Options forfeited by a Participant shall not thereafter be eligible for purchase by the Participant, but may be made subject to Stock Options granted to other Participants. VIII. NO CONTRACT OF EMPLOYMENT Nothing in this Plan shall confer upon the Participant the right to continue in the employ of the Company, or any Participating Subsidiary, nor shall it interfere in any way with the right of the Company, or any such Participating Subsidiary, to discharge the Participant at any time for any reason whatsoever, with or without cause. Nothing in this Article VIII shall affect any rights or obligations of the Company or any Participant under any written contract of employment. IX. NO RIGHTS AS A STOCKHOLDER A Participant shall have no rights as a stockholder with respect to any shares of Common Stock subject to a Stock Option. Except as provided in Section 6.2, no adjustment shall be made in the number of shares of Common Stock issued to a Participant, or in any other rights of the Participant upon exercise of a Stock Option by reason of any dividend, distribution or other right granted to stockholders for which the record date is prior to the date of exercise of the Participant's Stock Option. X. ASSIGNABILITY No Stock Option granted under this Plan, nor any other rights acquired by Participant under this Plan, shall be assignable or transferable by a Participant, other than by will or the laws of descent and distribution, and Stock Options issued to a Participant are exercisable during his lifetime only by him. Notwithstanding the preceding sentence, the Board or Committee may, in its sole discretion, permit the assignment or transfer of an NSO and the exercise thereof by a person other than a Participant, on such terms and conditions as the Board or Committee in its sole discretion may determine. Any such terms shall be determined at the time the NSO is granted, and shall be set forth in the Option Agreement. In the event of his death, the Stock Option may be exercised by the Personal Representative of the Participant's estate or by the successor or successors in -6- interest determined under the Participant's will or under the applicable laws of descent and distribution. XI. MERGER OR LIQUIDATION OF THE COMPANY 11.1 LIQUIDATION. In the event of a dissolution or liquidation of the Company, all Stock Options shall terminate immediately prior to the consummation of such dissolution or liquidation, unless otherwise provided by the Board. The Board may, in the exercise of its sole discretion, give each Participant the right to exercise his or her Stock Option(s) as to Shares as to which the Stock Option(s) would not otherwise be exercisable. 11.2 SALE OF ASSETS, MERGER OR CONSOLIDATION. In the event of a sale of all or substantially all of the assets of the Company, or the merger or consolidation of the Company with or into another corporation in a transaction in which the Company does not survive, the Board, in its sole discretion, may provide for the acceleration of the exercise date of some or all of the non-exercisable portion of any outstanding Stock Options, and/or may provide for the termination of any Stock Options immediately prior to the consummation of the transaction, and/or may provide for the replacement of any Stock Options with comparable options to purchase stock of such other corporation. XII. AMENDMENT The Board of Directors may from time to time alter, amend, suspend or discontinue the Plan, including, where applicable, any modifications or amendments as it shall deem advisable in order that ISOs will be classified as incentive stock options under the Code, or in order to conform to any regulation or to any change in any law or regulation applicable thereto; provided, however, that no such action shall adversely affect the rights and obligations with respect to Stock Options at any time outstanding under the Plan; and provided further that no such action shall, without the approval of the stockholders of the Company, (i) increase the maximum number of shares of Common Stock that may be made subject to Stock Options (unless necessary to effect the adjustments required by Section 6.2), (ii) materially increase the benefits accruing to Participants under the Plan, or (iii) materially modify the requirements as to eligibility for participation in the Plan. -7- XIII. REGISTRATION OF OPTIONED SHARES The Stock Options shall not be exercisable unless the purchase of such optioned shares is pursuant to an applicable effective registration statement under the Securities Act of 1933, as amended, or unless, in the opinion of the Company, the proposed purchase of such optioned shares would be exempt from the registration requirements of the Securities Act of 1933, as amended, and from the registration or qualification requirements of applicable state securities laws. As a condition to the exercise of a Stock Option, the Company may impose various conditions, including a requirement that the person exercising such Stock Option represent and warrant, at the time of such exercise, that the Shares are being purchased for investment and without any present intention to sell or distribute the Shares to be received. XIV. WITHHOLDING TAXES The Company or Participating Subsidiary shall take such steps as it shall deem necessary or appropriate for the withholding of any taxes which the Company or the Participating Subsidiary is required by any law or regulation of any governmental authority, whether federal, state or local, domestic or foreign to withhold in connection with any Stock Options. All withholding taxes may, at the sole discretion of the Board or Committee, be satisfied by the withholding of a sufficient number of exercised Shares which, valued at Fair Market Value on the date of exercise, would be equal to the total withholding obligation of the Optionee for the exercise of such Stock Option. XV. BROKERAGE ARRANGEMENTS The Board or Committee, in its discretion, may enter into arrangements with one or more banks, brokers, or other financial institutions to facilitate the disposition of shares acquired upon exercise of Stock Options including, without limitation, arrangements for the simultaneous exercise of Stock Options and the sale of shares acquired upon exercise. -8- XVI. NONEXCLUSIVITY OF THE PLAN Neither the adoption of the Plan by the Board of Directors nor the submission of the Plan to stockholders of the Company for approval shall be construed as creating any limitations on the power or authority of the Board of Directors to adopt such other or additional incentive or other compensation arrangements of whatever nature as the Board of Directors may deem necessary or desirable or preclude or limit the continuation of any other plan, practice or arrangement for the payment of compensation or fringe benefits to employees, consultants or directors generally, or to any class or group of employees, which the Company or any Participating Subsidiary now has lawfully put into effect, including, without limitation, any retirement, pension, savings and stock purchase plan, insurance, death and disability benefits and executive short-term incentive plans. XVII. EFFECTIVE DATE This Plan was adopted by the Board of Directors and became effective on March 15, 1994, subject to the approval of the Company's shareholders within twelve (12) months thereafter. No Stock Options shall be granted subsequent to ten years after the effective date of the Plan.
