Such eligible individuals may receive Options hereunder in accordance with the provisions of Section 5.2 below. 5.2 Grants of Options. Subject to the provisions of the Plan, the Committee shall have the authority and sole discretion to determine and designate, from time to time, those individuals (from among the individuals eligible for a grant of Options under the Plan pursuant to Section 5.1 above) to Page 5 whom Options will actually be granted, the Option Price of the shares covered by any Options granted, the manner in and conditions under which Options are exercisable (including, without limitation, any limitations or restrictions thereon), and the time or times at which Options shall be granted. In making such determinations, the Committee may take into account the nature of the services rendered by the respective employees to whom Options may be granted, their present and potential contributions to the Company's success and such other factors as the Committee, in its sole discretion, shall deem relevant. In its authorization of the granting of an Option hereunder, the Committee shall specify the name of the Optionee, the number of shares of stock subject to such Option and whether such Option is an ISO or a NQSO. The Committee may grant, at any time, new Options to an Optionee who previously has received Options, whether such Options include prior Options that still are outstanding, previously have been exercised in whole or in part, have expired or are canceled in connection with the issuance of new Options. No individual shall have any claim or right to be granted Options under the Plan. 5.3 Limitation on Exercisability of ISO's.

Upon the grant of an Option hereunder, the Committee shall prepare (or cause to be prepared) an Option Agreement. The Committee shall present such Option Agreement to the Optionee. Upon execution of such Option Agreement by the Optionee, such Option shall be deemed to have been granted effective as of the date of grant. The failure of the Optionee to execute the Option Agreement within 30 days after the date of the receipt of same shall render the Option Agreement and the underlying Option null and void ab initio. 6.2 Optionee and Number of Shares. Each Option Agreement shall state the name of the Optionee and the total number of shares of the Common Stock to which it pertains, the Option Price, the Beneficiary of the Optionee and the date as of which the Option was granted under this Plan. 6.3 Vesting. Each Option shall first become exercisable (i.e., vested) with respect to the shares subject to such Option as of the first anniversary of the date the Option is granted; provided, the Committee may, in its sole discretion, waive the application of this section and may provide a different vesting schedule in an Option Agreement. Prior to said date, the Option shall be unexercisable in its entirety. Notwithstanding the foregoing, all Options granted to an Optionee shall become immediately vested and exercisable for 100% of the number of shares subject to the Options upon the Optionee's becoming Disabled (within the meaning of Section 2.12 hereof) or upon his death or upon a Change in Control. Other than as provided in the preceding sentences, if an Optionee ceases to be an employee of the Company, his rights with regard to all non-vested Options shall cease immediately. 6.4 Option Price. The Option Price of the shares of Common Stock underlying each Option shall be the Fair Market Value of the Common Stock on the date the Option is granted, unless otherwise determined by the Committee; provided, in no event shall the Option Price of any ISO be less than 100% Page 6 (110% in the case of ISO's of Optionees who own more than ten percent of the voting power of all classes of stock of either the Company or any "parent" or "subsidiary" corporation of the Company (within the meaning of subsections (e) and (f) of Code ss.424)) of the Fair Market Value of the Common Stock on the date the Option is granted. Upon execution of an Option Agreement by both the Company and Optionee, the date as of which the Committee granted the Option as specified in the Option Agreement shall be considered the date on which such Option is granted. 6.5 Terms of Options. Terms of Options granted under the Plan shall commence on the date of grant and shall expire on such date as the Committee may determine for each Option; provided, in no event shall any Option be exercisable after ten years (five years in the case of ISO's granted to Optionees who own more than ten percent of the voting power of all classes of stock of either the Company or any parent or subsidiary) from the date the Option is granted. No Option shall be granted hereunder after ten years from the earlier of (a) the date the Plan is approved by the shareholders, or (b) the date the Plan is adopted by the Board. 6.6 Terms of Exercise. The exercise of an Option may be for less than the full number of shares of Common Stock subject to such Option, but such exercise shall not be made for less than (i) 100 shares or (ii) the total remaining shares subject to the Option, if such total is less than 100 shares. Subject to the other restrictions on exercise set forth herein, the unexercised portion of an Option may be exercised at a later date by the Optionee. 6.7 Method of Exercise. All Options granted hereunder shall be exercised by written notice directed to the Secretary of the Company at its principal place of business or to such other person as the Committee may direct. Each notice of exercise shall identify the Option which the Optionee is exercising (in whole or in part) and shall be accompanied by payment of the Option Price for the number of shares specified in such notice and by any documents required by Section 8.1. The Company shall make delivery of such shares within a reasonable period of time; provided, if any law or regulation requires the Company to take any action (including, but not limited to, the filing of a registration statement under the 1933 Act and causing such registration statement to become effective) with respect to the shares specified in such notice before the issuance thereof, then the date of delivery of such shares shall be extended for the period necessary to take such action. For Options which are ISO's, written statements on Form 3921 shall be furnished to the Optionee in accordance with Code (S)6039 on or before January 31 of the year following the year in which the Option was exercised. See Treas. Reg. (S)(S)1.6039-1 and -2, and 301.6039.1. 6.8 Medium and Time of Payment. (a) The Option Price shall be payable upon the exercise of the Option in an amount equal to the number of shares then being purchased times the per share Option Price. Payment, at the election of the Optionee (or his Beneficiary as provided in subsection (c) of Section 6.9), shall be (A) in cash; (B) by delivery to the Company of a certificate or certificates for shares of the Common Stock duly endorsed for transfer to the Company with signature guaranteed by a member firm of a national stock exchange or by a national or state bank or a federally chartered thrift institution (or guaranteed or notarized in such other manner as the Committee may require) or by instructing the Company to retain shares of Common Stock upon the exercise of the Option with a Fair Market Value equal to the exercise price as payment; or (C) by a combination of (A) and (B). (b) If the Optionee delivers Common Stock with a value that is less than the total Option Price, then such Optionee shall pay the balance of the total Option Price in cash, other property or services, as provided in subsection (a) above. Page 7 (c) In addition to the payment of the purchase price of the shares then being purchased, an Optionee also shall pay in cash (or have withheld from his normal pay) an amount equal to, or by instructing the Company to retain Common Stock upon the exercise of the Option with a Fair Market Value equal to, the amount, if any, which the Company at the time of exercise is required to withhold under the income tax or Federal Insurance Contribution Act tax withholding provisions of the Code, of the income tax laws of the state of the Optionee's residence, and of any other applicable law. 6.9 Effect of Termination of Employment, Disability or Death. Except as provided in subsections (a), (b) and (c) below, no Option shall be exercisable unless the Optionee thereof shall have been an employee of the Company from the date of the granting of the Option until the date of exercise; provided, the Committee, in its sole discretion, may waive the application of this Section with respect to any NQSO's granted hereunder and, instead, may provide a different expiration date or dates in a NQSO Option Agreement. (a) Termination of Employment. In the event an Optionee ceases to be an employee of the Company for any reason other than death or Disability, any Option or unexercised portion thereof granted to him shall terminate on and shall not be exercisable after the earliest to occur of (1) the expiration date of the Option, (2) three months after termination of employment or (3) the date on which the Company gives notice to such Optionee of termination of employment if employment is terminated by the Company for Cause (an Optionees resignation in anticipation of termination of employment by the Company for Cause shall constitute a notice of termination by the Company); provided, the Committee may provide in the Option Agreement that such Option or any unexercised portion thereof shall terminate sooner. Notwithstanding the foregoing, in the event that an Optionee's employment terminates for a reason other than death or Disability at any time after a Change of Control, the term of all Options of that Optionee shall be extended through the end of the three-month period immediately following the date of such termination; provided, this extension shall apply to ISO's only to the extent it does not cause the term of such ISO's to exceed the maximum term permitted under Code (S)422 or does not cause such ISO's to lose their status as ISO's. Prior to the earlier of the dates specified in the preceding sentences of this subsection (a), the Option shall be exercisable only in accordance with its terms and only for the number of shares exercisable on the date of termination of employment. The question of whether an authorized leave of absence or absence for military or government service or for any other reason shall constitute a termination of employment for purposes of the Plan shall be determined by the Committee, which determination shall be final and conclusive. (b) Disability. Upon the termination of an Optionee's employment due to Disability, any Option or unexercised portion thereof granted to him which is otherwise exercisable shall terminate on and shall not be exercisable after the earlier to occur of (1) the expiration date of such Option, or (2) one year after the date on which such Optionee ceases to be an employee of the Company due to Disability; provided, the Committee may provide in the Option Agreement that such Option or any unexercised portion thereof shall terminate sooner. Prior to the earlier of such date, such Option shall be exercisable only in accordance with its terms and only for the number of shares exercisable on the date such Optionee's employment ceases due to Disability. (c) Death. In the event of the death of the Optionee (1) while he is an employee of the Company, (2) within three months after the date on which such Optionee's employment terminated (for a reason other than Cause) as provided in subsection (a) above, or (3) within one year after the date on which such Optionee's employment terminated due to his Disability as provided in subsection (b), any Option or unexercised portion thereof granted to him which is otherwise exercisable may be exercised by his Beneficiary at any time prior to the expiration of one year from the date of death of such Optionee, but in no event later than the date of expiration of the option period; provided, the Committee may provide in the Option Agreement that such Option or any unexercised portion thereof shall terminate sooner. Such Page 8 exercise shall be effected pursuant to the terms of this Section as if such Beneficiary is the named Optionee. 6.10 Restrictions on Transfer and Exercise of Options. No Option shall be assignable or transferable by the Optionee except by transfer to a Beneficiary upon the death of the Optionee, and any purported transfer (other than as excepted above) shall be null and void. After the death of an Optionee and upon the death of the Optionee's Beneficiary, an Option shall be transferred only by will or by the laws of descent and distribution. During the lifetime of an Optionee, the Option shall be exercisable only by him; provided, however, that in the event the Optionee is incapacitated and unable to exercise Options, such Options may be exercised by such Optionee's legal guardian, legal representative, fiduciary or other representative whom the Committee deems appropriate based on applicable facts and circumstances. 6.11 Rights as a Shareholder. An Optionee shall have no rights as a shareholder with respect to shares covered by his Option until date of the issuance of the shares to him and only after the Option Price of such shares is fully paid. Unless specified in Article 7, no adjustment will be made for dividends or other rights for which the record date is prior to the date of such issuance. 6.12 No Obligation to Exercise Option. The granting of an Option shall impose no obligation upon the Optionee to exercise such Option. 6.13 Acceleration. The Committee shall at all times have the power to accelerate the vesting date of Options previously granted under this Plan. 6.14 Designation of Option as ISO or NQSO. Subject to the provisions of this Article, each Option granted under the Plan shall be designated either as an ISO or a NQSO. An Option Agreement evidencing both an ISO and a NQSO shall identify clearly the status and terms of each Option. 6.15 ISO's Converted to NQSO's. In the event any part or all of an Option granted under the Plan which is intended to be an ISO at any time fails to satisfy all of the requirements of an ISO, then such ISO shall be split into an ISO and NQSO so that the portion of the Option, if any, that still qualifies as an ISO shall remain an ISO and the portion that does not qualify as an ISO shall become a NQSO. Such split of an Option into an ISO portion and a NQSO portion shall be evidenced by one or more Option Agreements, as long as each Option is identified clearly as to its status as an ISO or NQSO. ARTICLE 7 Adjustments Upon Changes in Capitalization 7.1 Recapitalization. In the event that the outstanding shares of the Common Stock of the Company are hereafter increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of a recapitalization, reclassification, stock split, combination of shares or dividend payable in shares of the Common Stock, the following rules shall apply: (a) The Committee shall make an appropriate adjustment in the number and kind of shares available for the granting of Options under the Plan. (b) The Committee also shall make an appropriate adjustment in the number and kind of shares as to which outstanding Options, or portions thereof then unexercised, shall be exercisable; any such adjustment in any outstanding Options shall be made without change in the total price applicable to the unexercised portion of such Option and with a corresponding adjustment in the Option Price per share. No fractional shares shall be issued or optioned in making the foregoing adjustments, and the Page 9 number of shares available under the Plan or the number of shares subject to any outstanding Options shall be the next lower number of shares, rounding all fractions downward. (c) Any adjustment to or assumption of ISO's under this Section shall be made in accordance with Code (S)424(a) and the regulations promulgated thereunder so as to preserve the status of such Options as ISO's under Code (S)422. (d) If any rights or warrants to subscribe for additional shares are given pro rata to holders of outstanding shares of the class or classes of stock then set aside for the Plan, each Optionee shall be entitled to the same rights or warrants on the same basis as holders of the outstanding shares with respect to such portion of his Option as is exercised on or prior to the record date for determining shareholders entitled to receive or exercise such rights or warrants. 7.2 Reorganization. Subject to any required action by the shareholders, if the Company shall be a party to any reorganization involving merger, consolidation, acquisition of the stock or acquisition of the assets of the Company which does not constitute a Change of Control, the Committee, in its discretion, may declare that: (a) any Option granted but not yet exercised shall pertain to and apply, with appropriate adjustment as determined by the Committee, to the securities of the resulting corporation to which a holder of the number of shares of the Common Stock subject to such Option would have been entitled; (b) any or all outstanding Options granted hereunder shall become immediately nonforfeitable and fully exercisable or vested (to the extent permitted under federal or state securities laws); and/or (c) any or all Options granted hereunder shall become immediately nonforfeitable and fully exercisable or vested (to the extent permitted under federal or state securities laws) and are to be terminated after giving at least 30 days' notice to the Optionees to whom such Options have been granted. 7.3 Dissolution and Liquidation. If the Board adopts a plan of dissolution and liquidation that is approved by the shareholders of the Company, the Committee shall give each Optionee written notice of such event at least ten days prior to its effective date, and the rights of all Optionees shall become immediately nonforfeitable and fully exercisable or vested (to the extent permitted under federal or state securities laws). 7.4 Limits on Adjustments. Any issuance by the Company of stock of any class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of the Common Stock subject to any Option, except as specifically provided otherwise in this Article. The grant of Options pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge, consolidate or dissolve, or to liquidate, sell or transfer all or any part of its business or assets. All adjustments the Committee makes under this Article shall be conclusive. ARTICLE 8 Agreement by Optionee and Securities Registration 8.1 Agreement. If, in the opinion of counsel to the Company, such action is necessary or desirable, no Options shall be granted to any Optionee, and no Option shall be exercisable, unless, at the time of grant or exercise, as applicable, such Optionee (i) represents and warrants that he will acquire the Page 10 Common Stock for investment only and not for purposes of resale or distribution, and (ii) makes such further representations and warranties as are deemed necessary or desirable by counsel to the Company with regard to holding and resale of the Common Stock. The Optionee shall, upon the request of the Committee, execute and deliver to the Company an agreement or affidavit to such effect. Should the Committee have reasonable cause to believe that such Optionee did not execute such agreement or affidavit in good faith, the Company shall not be bound by the grant of the Option or by the exercise of the Option. All certificates representing shares of Common Stock issued pursuant to the Plan shall be marked with the following restrictive legend or similar legend, if such marking, in the opinion of counsel to the Company, is necessary or desirable: The shares represented by this certificate [have not been registered under the Securities Act of 1933, as amended, or the securities laws of any state] [and] [are held by an "affiliate" (as such term is defined in Rule 144 promulgated by the Securities and Exchange Commission under the Securities Act of 1933, as amended) of the Corporation]. Accordingly, these shares may not be sold, hypothecated, pledged or otherwise transferred except (i) pursuant to an effective registration statement under the Securities Act of 1933, as amended, and any applicable securities laws or regulations of any state with respect to such shares, (ii) in accordance with Securities and Exchange Commission Rule 144, or (iii) upon the issuance to the Corporation of a favorable opinion of counsel or the submission to the Corporation of such other evidence as may be satisfactory to the Corporation that such proposed sale, assignment, encumbrance or other transfer will not be in violation of the Securities Act of 1933, as amended, or any applicable securities laws of any state or any rules or regulations thereunder. Any attempted transfer of this certificate or the shares represented hereby which is in violation of the preceding restrictions will not be recognized by the Corporation, nor will any transferee be recognized as the owner thereof by the Corporation. If the Common Stock is (A) held by an Optionee who is not an "affiliate," as that term is defined in Rule 144 of the 1933 Act, or who ceases to be an "affiliate," or (B) registered under the 1933 Act and all applicable state securities laws and regulations as provided in Section 8.2, the Committee, in its discretion and with the advice of counsel, may dispense with or authorize the removal of the restrictive legend set forth above or the portion thereof which is inapplicable. 8.2 Registration. In the event that the Company in its sole discretion shall deem it necessary or advisable to register, under the 1933 Act or any state securities laws or regulations, any shares with respect to which Options have been granted hereunder, then the Company shall take such action at its own expense before delivery of the certificates representing such shares to an Optionee. In such event, and if the shares of Common Stock of the Company shall be listed on any national securities exchange or on The Nasdaq National Market at the time of the exercise of any Option, the Company shall make prompt application at its own expense for the listing on such stock exchange or The Nasdaq National Market of the shares of Common Stock to be issued. ARTICLE 9 Effective Date The Plan shall be effective as of the Effective Date, and no Options shall be granted hereunder prior to said date. Adoption of the Plan shall be approved by the shareholders of the Company at the earlier of (i) the annual meeting of the shareholders of the Company which immediately follows the date of the first grant or award of Options hereunder, or (ii) 12 months after the adoption of the Plan by the Board, but in no event earlier than 12 months prior to the adoption of the Plan by the Board.

Reg. (S)1.162-27(e)(4). Clauses (ii), (iii) and (iv) of the preceding sentence shall be interpreted in accordance with the provisions of paragraph (b)(2) of Rule 16b-3 of the 1934 Act.
