The Committee may grant Options to Participants at any time during the term of this Plan. Options may be either [1 ] Incentive Stock Options or [2] Nonstatutory Stock Options. Each Option will be evidenced by a Stock Option Agreement specifying the type of Option granted, the exercise price, the duration of the Option, the number of shares of Stock to which the Option pertains and any other terms and conditions not inconsistent with the Plan that the Committee believes advisable. 6.02 OPTION PRICE. Options will have an exercise price that is not less than the Fair Market Value of the Stock on the date the Option is granted. However, any Incentive Stock Option granted to a Participant who owns [as defined in Code Section 424(d)] Stock possessing more than 10 percent of the total combined voting power of all classes of Stock will have an exercise price that is at least 110 percent of the Fair Market Value of the affected Stock on the date the Option is granted. 6.03 EXERCISE OF OPTIONS. [1] Options awarded to a Participant under Section 6.01 may be exercised at the times and subject to the restrictions and conditions (including a vesting schedule) that the Committee; at the time the Option is granted, may specify in the Stock Option Agreement. However, unless the Committee specifies otherwise in the Stock Option Agreement: [a] No Participant will be credited with vesting service for any period after his or her relationship with the Company ends; [b] No Option may be exercised more than 10 years after the date on which it is granted; and [c] No Incentive Stock Option granted to a Participant who owns [as defined in Code Section 424(d)] Stock possessing more than 10 percent of total combined voting - 8 - <Page> power of all classes of Stock maybe exercised more than 5 years after the date it is granted; [2] An Option may not be exercised for a fraction of a share; [31 The Committee may prohibit a Participant from exercising Options for fewer than the minimum number of shares specified by the Committee in the Stock Option Agreement but only if that prohibition does not prevent a Participant from acquiring the full number of shares of Stock for which Options are then exercisable; [4] An Option is treated as having been exercised when written notice of the exercise has been given to the Company in accordance with the terms of the Stock Option Agreement by the Participant and the Company has received full payment for the shares of Stock with respect to which the Option is exercised; and [5] Regardless of the vesting schedule given above, all Options will be fully exercisable by the beneficiary of a deceased Participant, subject to the limits described in Section 7.01 [3]. 6.04 INCENTIVE STOCK OPTIONS. Notwithstanding anything in the Plan to the contrary: [1] No provision of this Plan relating to Incentive Stock Options will be interpreted, amended or altered, nor will any discretion or authority granted under the Plan be exercised, in a manner that is inconsistent with Code Section 422 or, without the consent of any affected Participant, to cause any Incentive Stock Option previously granted to fail to qualify for the federal income tax treatment afforded under Code Section 421; [2] The aggregate Fair Market Value of the Stock (determined as of the time an Incentive Stock Option is granted) with respect to which Incentive Stock Options are exercisable for the first time by any Participant during any calendar year (under all option plans of the Company and all Subsidiaries of the Company) will not exceed $100,000; and [3] No Incentive Stock Option will be granted to any Participant who is not an Employee. 7.00 TERMINATION OF RELATIONSHIP AND BUY OUT DURING RELATIONSHIP 7.01 EXERCISE PERIOD. Regardless of the term of the Option prescribed in Section 6.03, a Participant whose relationship with the Company and all of its Subsidiaries is severed for any reason may exercise any outstanding Options that are then exercisable under the terms of Section 6.03 and the Stock Option Agreement for the period specified in the Stock Option Agreement. However, this period may be no longer than: [1] 90 days after the relationship is severed for any reason other than Disability; or [2] 12 months after the relationship severs because of Disability. - 9 - <Page> 7.02 RIGHT OF FIRST REFUSAL. [1] Unless the Committee specifies otherwise in the Stock Option Agreement, all Options must reserve to the Company the right of first refusal to repurchase any Stock acquired by a Participant or a beneficiary through the exercise of Options. [2] This right of first refusal will survive the Participant's relationship with the Company and its Subsidiaries. [3] A Participant, former Participant or beneficiary must notify the Company, in writing, of any intent to sell any shares of Stock acquired through the exercise of Options. To be effective, this notice must specify the number of shares to be sold, the intended purchaser, the proposed date of the sale and the proposed purchase price. The Company then will have six months from the date it receives the completed notice to exercise its right to purchase from the Participant, former Participant or beneficiary any or all of the shares of Stock described in this notice at the Stock's then current Fair Market Value. If the Company elects not to purchase the affected shares of Stock (or does not respond within the six-month period described in the preceding sentence), the right of first refusal will lapse and the Participant, former Participant or beneficiary may sell the Stock but only under the terms specified and to the person described in the notice given to the Committee under this subsection. [4] If the identity of the other party or any of the terms described in notice described in Section 7.02[3] change, the Participant, former Participant or beneficiary must give another written notice to the Company containing the information described in Section 7.02[3] and the Company will have an additional six months to decide whether or not to exercise its Right of First Refusal under this section. This same procedure must be followed with respect to any additional changes in the identity of the proposed purchase or the terms of the sale. 7.03 REPURCHASE OPTION. Unless the Committee specifies otherwise in the Stock Option Agreement, all Options will reserve to the Company a repurchase option exercisable when: [1] A Participant who is an Employee terminates employment with the Company and all Subsidiaries for any reason (including death or Disability) without becoming an Eligible Director; [2] Any Participant (whether or not an Employee) exercises any Option after terminating his or her relationship with the Company and all Subsidiaries and while he or she is not an Eligible Director; and [3] A beneficiary of any deceased Participant exercises any Option after the Participant's death. The price paid for Stock repurchased under this section will be Fair Market Value at the time of the repurchase, payable in cash or cash equivalents. The Company will complete any repurchase under this section as soon as administratively possible after the date it notifies the former Participant or beneficiary of its intention to exercise its repurchase option under this section. - 10 - <Page> 7.04 BUY OUT OF OPTION GRANTS. At any time after an Option becomes exercisable, the Committee may elect, in its sole discretion and without the consent of the Participant, to cancel the Option and pay to the Participant the excess of the Fair Market Value of the Stock subject to the cancelled Option over the Option price at the date the Committee provides written notice ("Buy Out Notice") of its intention to exercise the right reserved in this section. The Company will complete any buy out made under this section as soon as administratively possible after the date of the Buy Out Notice. At the Committee's option, payment of the buy out amount may be made in cash, in whole shares of Stock or partly in cash and partly in Stock. The number of whole shares of Stock, if any, included in the buy out amount will be determined by dividing the amount of the payment to be made in Stock by the Fair Market Value of a share of Stock as of the date of. the Buy Out Notice. 8.00 CHANGE IN CONTROL 8.01 ACCELERATED VESTING AND PAYMENT. Subject to Section 8.02, if a Change in Control occurs, all outstanding and exercisable Options will become fully vested and each Option will be cancelled as of the date of the Change in Control in exchange for a payment in cash equal to the difference between [1] the Stock's Fair Market Value (disregarding the effect of the Right of First Refusal and Repurchase Options described in Sections 7.02 and 7.03 and the Buy Out provision described in Section 7.04) and [2] the Option price defined in Section 6.02. 8.02 ALTERNATIVE AWARDS. Subject to Section 7.04, no cancellation or acceleration under Section 8.01, cash settlement or other payment will occur with respect to any Award or any class of Awards if: [1] The Committee reasonably decides in good faith before the Change in Control that the Award or Awards will be honored or assumed by the new controlling entity or person, or that new rights will be substituted ("Alternative Award") by the new . controlling person or entity immediately after the Change in Control; and [2] The Alternative Award: [a] Is based on stock .which is, or within 60 days after the Change in Control will be, traded on an established securities market; [b] Provides each affected Participant with rights and entitlements substantially equivalent to or better than the rights, terms and conditions of the affected Award, including an identical or better exercise or vesting schedule and identical or better timing and methods of payment; [e] Has substantially the same economic value as the affected Award (determined at the time of the Change in Control); and [d] Provides that, if the Participant's relationship with the Company and all Subsidiaries is completely severed involuntarily (and, if the Participant is an Employee, is constructively terminated) within 12 months after the Change in Control, any conditions on a Participant's rights under, or any restrictions on - 11 - <Page> transfer or exercisability applicable to, the Alternative Award will be waived or will lapse. [3] A "constructive termination" means a voluntary termination by a Participant who is an Employee following: [a] A permanent reduction in the Employee's title, duties, responsibilities or status, as compared to either [i] his or her title, duties, responsibilities or status immediately before a Change in Control; or [ii] any enhanced or increased title, duties, responsibilities or status occurring after the Change in Control; [b] The permanent assignment to the Employee of duties inconsistent with [i] the Employee's office on the date of the Change in Control, [ii] any enhanced or increased duties occurring after the Change in Control or [iii] any more senior office to which he or she is promoted after the Change in Control; [c] A 15 percent (or larger) reduction of the annualized base salary rate or total annualized salary rate (including bonuses, employee benefits and fringe benefits) the Employee was receiving from the Company and Subsidiaries immediately before the Change in Control or any increased annualized base salary rate or total annualized salary rate he or she receives from the Company and Subsidiaries after the Change in Control; or [d] A requirement that the Employee relocate his or her principal office or worksite (or the indefinite assignment of the Employee) to a location more than 50 miles distant from [i] the principal office or worksite to which he or she was permanently assigned immediately before the Change in Control or [ii] any location to which the Employee is permanently assigned, with his or her consent, after the Change in Control. Any comparison of a Participant's duties, responsibilities or status under this section will be based on those that are permanently assigned to the Participant and not on temporarily assigned duties, responsibilities or status. 8.03 OPTIONS GRANTED WITHIN SIX MONTHS OF A CHANGE IN CONTROL. Any Option that was granted within six months before the date on which a Change in Control occurs and which is held by a person subject to the reporting requirements of Act Section 16(a) may be cashed out under Section 8.01 only if the Company's counsel concludes that that cash out will not subject the Participant to liability under Act Section 16(b). 9.00 AMENDMENT, MODIFICATION AND TERMINATION OF PLAN The Board or the Committee may terminate, suspend or amend the Plan at any time. However: [1] No Plan amendment may cause any Committee member to lose his or her status as a "disinterested person" as defined in Rule 16b-3 under the Act with respect to any employee benefit plan of the Company or cause the Plan to fail to satisfy the requirements of Rule 16b-3; - 12 - <Page> [2] No amendment, modification or termination of the Plan may adversely affect any Award granted before the effective date of that amendment under the Plan, without the consent of the affected Participant except: [a] An amendment to comply with the provisions of any applicable law, including the Act and the Code; and [b] Any amendment intended to preserve the status of any Incentive Stock Option or the status of the Plan under Code Section 162(m) as a source of performance based compensation as defined in Code Section 162(m)(4)(C); [3] No amendment may be made to Section 8.03 or to any other provision of the Plan relating to Options issued to Eligible Directors within six months of the last date on which any provision was amended; and [4] Any amendment, termination or suspension may be made without the approval of the shareholders of the Company unless shareholder approval is required: [a] To satisfy the requirements of Rule 16b-3 under the Act; [b] To satisfy applicable requirements of the Act and the Code; or [c] To satisfy applicable requirements of any securities exchange on which any of the Company's equity securities are listed. 10.00 MISCELLANEOUS 10.01. NONTRANSFERABILITY OF AWARDS. Awards granted under the Plan may not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. All rights with respect to Awards granted to a Participant under the Plan may be exercised during his or her lifetime only by such Participant and after death only by the Participant's beneficiary as provided in Sections 7.01 and 10.02. 10.02 BENEFICIARY DESIGNATION. Each Participant may from time to time name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid or by whom any right under the Plan is to be exercised in case of the Participant's death. Each designation will revoke all earlier designations made by the same Participant, must be in a form prescribed by the Committee and attached to the Stock Option Agreement and will be effective only when filed in writing with the Committee. In the absence of an effective beneficiary designation, the Participant's beneficiary will be his or her surviving spouse, if any, or otherwise his or her estate. 10.03 NO GUARANTEE OF EMPLOYMENT OR PARTICIPATION. Nothing in the Plan will interfere with or limit in any way the right of the Company or any Subsidiary to terminate any Participant's employment at any time or to confer upon any Participant any right to continue as an Employee or Eligible Director.

Nothing in the Plan confers on an Eligible Director a right to continue to serve on the Board or to be nominated for reelection to the Board. - 13 - <Page> 10.04 TAX WITHHOLDING. The Company will withhold from other amounts owed to the Participant, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state and local withholding tax requirements on any Award, exercise or cancellation of an Option or purchase of Stock and the Company may defer payment of cash or issuance of Stock until these requirements are satisfied. The Committee may, in its discretion, permit a Participant to elect, subject to conditions the Committee establishes, to reimburse the Company for this withholding obligation through one or more of the following methods: [1] By having shares of Stock otherwise issuable under the Plan withheld by the Company (but only to the extent of the minimum amount that must be withheld to comply with applicable state, federal and local income; employment and wage tax laws); [2] By delivering to the Company previously acquired shares of Stock; [3] By remitting cash to the Company; or [4] By remitting a personal check immediately payable to the Company. 10.05 INDEMNIFICATION. Each person who is or was a member of the Committee or of the Board will be indemnified and held harmless by the Company against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any, claim, action, suit or proceeding to which he or she may be made a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company's approval; or paid by him or her in. satisfaction of any judgment in any such action, suit or proceeding against him or her, provided he or she gives the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it in his or her own behalf. The foregoing right of indemnification is not exclusive and is independent of any other rights of indemnification to which such persons may be entitled under the Company's Articles of Incorporation or Code of Regulations, by contract, as a matter of law, or otherwise. 10.06 NO LIMITATION ON COMPENSATION. Nothing in the Plan is to be construed to limit the right of the Company to establish other plans or to pay compensation to its employees or directors, in cash or property, in a manner which is not expressly authorized under the Plan. 10.07 REQUIREMENTS OF LAW. The grant of Awards and the issuance of shares of Stock will be subject to all applicable laws, rules and regulations and to all required approvals of any governmental agencies or national securities exchanges. Also, no Stock will be issued under the Plan unless the Company is satisfied that that issuance will comply with applicable federal and state securities laws. Certificates for Stock delivered under the Plan may be subject to any stock transfer orders and other restrictions that the Committee believes to be advisable under the rules, regulations and other requirements of the Securities and Exchange Commission; any stock exchange upon which the Stock is then listed or traded; the NASDAQ National Market or any applicable federal or state securities law. The Committee may cause a legend or legends to be placed on any such certificates to make appropriate reference to such restrictions. - 14 - <Page> 10.08 TERM OF PLAN. The Plan will be effective upon its adoption by the Committee, subject to approval by the Board and approval by the affirmative vote of the holders of a majority of the shares of voting stock present in person or represented by proxy at the first Annual Meeting of Shareholders occurring after the Board approves the Plan. The Plan will continue in effect, unless sooner terminated pursuant to Section 9.00, until the tenth anniversary of the date on which it is adopted by the Board or approval by the Company's shareholders, whichever is earliest. 10.09 GOVERNING LAW.

Plan Awards are incentives designed to promote the purposes described in Section 1.00. Also, Awards are not compensation for purposes of calculating an Employee's rights under any employee benefit plan. MEDVEST HOLDINGS CORPORATION By: /s/ Charles J.
