SECTION 2.
PURPOSE

    The purpose of the Plan is to promote the success of the Company and its Subsidiaries by facilitating the retention of competent personnel and by furnishing incentive to officers and directors upon whose efforts the success of the Company and its Subsidiaries will depend to a large degree. It is the intention of the Company to carry out the Plan through the granting of "nonqualified stock options."

SECTION 3.
EFFECTIVE DATE OF PLAN

    The Plan shall be effective as of January 20, 1999, the date of adoption by the Board of Directors.

SECTION 4.
ADMINISTRATION

    The Plan shall be administered by the Board of Directors of the Company (hereinafter referred to as the "Board") or by a Committee which may be appointed by the Board from time to time (collectively referred to as the "Administrator"). The Administrator shall have all of the powers vested in it under the provisions of the Plan, including but not limited to exclusive authority (where applicable and within the limitations described in the Plan) to determine, in its sole discretion, whether a nonqualified stock option shall be granted, the individuals to whom, and the time or times at which, options shall be granted, the number of shares subject to each option and the option price and terms and conditions of each option. The Administrator shall have full power and authority to administer and interpret the Plan, to make and amend rules, regulations and guidelines for administering the Plan, to prescribe the form and conditions of the respective stock option agreements (which may vary from Optionee to Optionee) evidencing each option and to make all other determinations necessary or advisable for the administration of the Plan. The Administrator's interpretation of the Plan, and all actions taken and determinations made by the Administrator pursuant to the power vested in it hereunder, shall be conclusive and binding on all parties concerned.

    No member of the Board or the Committee shall be liable for any action taken or determination made in good faith in connection with the administration of the Plan. In the event the Board appoints a Committee as provided hereunder, any action of the Committee with respect to the administration of the Plan shall be taken pursuant to a majority vote of the Committee members or pursuant to the written resolution of all Committee members.

SECTION 5.
PARTICIPANTS

    The Administrator shall from time to time, at its discretion and without approval of the shareholders, designate those officers and directors (including Outside Directors) of the Company or of any Subsidiary to whom nonqualified stock options shall be granted. The Administrator may grant additional nonqualified stock options under this Plan to some or all participants then holding options or may grant options solely or partially to new participants. In designating participants, the Administrator shall also determine the number of shares to be optioned to each such participant. The Board may from time to time designate individuals as being ineligible to participate in the Plan.

SECTION 6.
STOCK

    The Stock to be optioned under this Plan shall consist of authorized but unissued shares of Option Stock. Six hundred thousand (600,000) shares of Option Stock shall be reserved and available for options under the Plan; provided, however, that the total number of shares of Option Stock reserved for options under this Plan shall be subject to adjustment as provided in Section 12 of the Plan. In the event that any outstanding option under the Plan for any reason expires or is terminated prior to the exercise thereof, the shares of Option Stock allocable to the unexercised portion of such option shall continue to be reserved for options under the Plan and may be optioned hereunder.

SECTION 7.
DURATION OF PLAN

    Nonqualified stock options may be granted pursuant to the Plan from time to time after the effective date of the Plan and until the Plan is discontinued or terminated by the Board. Any nonqualified stock option granted prior to the termination of the Plan by the Board shall remain in full force and effect until the expiration of the option as specified in the written stock option agreement and shall remain subject to the terms and conditions of this Plan.

SECTION 8.
PAYMENT

    Optionees may pay for shares upon exercise of options granted pursuant to this Plan with cash, personal check, certified check, Common Stock of the Company valued at such Stock's then Fair Market Value, or such other form of payment as may be authorized by the Administrator. The Administrator may, in its sole discretion, limit the forms of payment available to the Optionee and may exercise such discretion any time prior to the termination of the option granted to the Optionee or upon any exercise of the option by the Optionee.

    With respect to payment in the form of Common Stock of the Company, the Administrator may require advance approval or adopt such rules as it deems necessary to assure compliance with Rule 16b-3, or any successor provision, as then in effect, of the General Rules and Regulations under the Securities Exchange Act of 1934, if applicable.

SECTION 9.
TERMS AND CONDITIONS OF NONQUALIFIED STOCK OPTIONS

    Each nonqualified stock option granted pursuant to this Section 9 shall be evidenced by a written Option Agreement. The Option Agreement shall be in such form as may be approved from time to time by the Administrator and may vary from Optionee to Optionee; provided, however, that each Optionee and each Option Agreement shall comply with and be subject to the following terms and conditions:

    (a) Number of Shares and Option Price.  The Option Agreement shall state the total number of shares covered by the nonqualified stock option. Unless otherwise determined by the Administrator, the option price per share shall be one hundred percent (100%) of the Fair Market Value of the Common Stock per share on the date the Administrator grants the option; provided, however, that the option price may not be less than eighty-five percent (85%) of the Fair Market Value of the Common Stock per share on the date of grant.

    (b) Term and Exercisability of Nonqualified Stock Option.  The term during which any nonqualified stock option granted under the Plan may be exercised shall be established in each

3

case by the Administrator. The Option Agreement shall state when the nonqualified stock option becomes exercisable and shall also state the maximum term during which the option may be exercised. In the event a nonqualified stock option is exercisable immediately, the manner of exercise of the option in the event it is not exercised in full immediately shall be specified in the stock option agreement. The Administrator may accelerate the exercisability of any nonqualified stock option granted hereunder which is not immediately exercisable as of the date of grant.

    (c) Withholding.  The Company or its Subsidiary shall be entitled to withhold and deduct from future wages of the Optionee all legally required amounts necessary to satisfy any and all withholding and employment-related taxes attributable to the Optionee's exercise of a nonqualified stock option. In the event the Optionee is required under the Option Agreement to pay the Company, or make arrangements satisfactory to the Company respecting payment of, such withholding and employment-related taxes, the Administrator may, in its discretion and pursuant to such rules as it may adopt, permit the Optionee to satisfy such obligation, in whole or in part, by electing to have the Company withhold shares of Common Stock otherwise issuable to the Optionee as a result of the option's exercise equal to the amount required to be withheld for tax purposes. Any stock elected to be withheld shall be valued at its Fair Market Value, as of the date the amount of tax to be withheld is determined under applicable tax law. The Optionee's election to have shares withheld for this purpose shall be made on or before the date the option is exercised or, if later, the date that the amount of tax to be withheld is determined under applicable tax law. Such election shall be approved by the Administrator and otherwise comply with such rules as the Administrator may adopt to assure compliance with Rule 16b-3, or any successor provision, as then in effect, of the General Rules and Regulations under the Securities Exchange Act of 1934, if applicable.

    (d) Other Provisions.  The Option Agreement authorized under this Section 9 shall contain such other provisions as the Administrator shall deem advisable.

SECTION 10.
TRANSFER OF OPTION

    The Administrator may, in its sole discretion, permit the Optionee to transfer any or all nonqualified stock options to any member of the Optionee's "immediate family" as such term is defined in Rule 16a-1(e) promulgated under the Securities Exchange Act of 1934, or any successor provision, or to one or more trusts whose beneficiaries are members of such Optionee's "immediate family" or partnerships in which such family members are the only partners; provided, however, that the Optionee receives no consideration for the transfer and such transferred nonqualified stock option shall continue to be subject to the same terms and conditions as were applicable to such nonqualified stock option immediately prior to its transfer.

SECTION 11.
RECAPITALIZATION, SALE, MERGER, EXCHANGE
OR LIQUIDATION

    In the event of an increase or decrease in the number of shares of Common Stock resulting from a subdivision or consolidation of shares or the payment of a stock dividend or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company, the number of shares of Option Stock reserved under Section 6 hereof and the number of shares of Option Stock covered by each outstanding option and the price per share thereof shall be automatically adjusted to reflect such change. Additional shares which may be credited pursuant to such adjustment shall be subject to the same restrictions as are applicable to the shares with respect to which the adjustment relates.

4

    Unless otherwise provided in the stock option agreement, in the event of an acquisition of the Company through the sale of substantially all of the Company's assets and the consequent discontinuance of its business or through a merger, consolidation, exchange, reorganization, reclassification, extraordinary dividend, divestiture or liquidation of the Company (collectively referred to as a "transaction"), all outstanding options shall become immediately exercisable, whether or not such options had become exercisable prior to the transaction; provided, however, that if the acquiring party seeks to have the transaction accounted for on a "pooling of interests" basis and, in the opinion of the Company's independent certified public accountants, accelerating the exercisability of such options would preclude a pooling of interests under generally accepted accounting principles, the exercisability of such options shall not accelerate. In addition to the foregoing, or in the event a pooling of interests transaction precludes the acceleration of the exercisability of outstanding options, the Board may provide for one or more of the following:

    (a) the complete termination of this Plan and cancellation of outstanding options not exercised prior to a date specified by the Board (which date shall give Optionees a reasonable period of time in which to exercise the options prior to the effectiveness of such transaction);

    (b) that Optionees holding outstanding nonqualified options shall receive, with respect to each share of Option Stock subject to such options, as of the effective date of any such transaction, cash in an amount equal to the excess of the Fair Market Value of such Option Stock on the date immediately preceding the effective date of such transaction over the option price per share of such options; provided that the Board may, in lieu of such cash payment, distribute to such Optionees shares of stock of the Company or shares of stock of any corporation succeeding the Company by reason of such transaction, such shares having a value equal to the cash payment herein; or

    (c) the continuance of the Plan with respect to the exercise of options which were outstanding as of the date of adoption by the Board of such plan for such transaction and provide to Optionees holding such options the right to exercise their respective options as to an equivalent number of shares of stock of the corporation succeeding the Company by reason of such transaction.

The Board may restrict the rights of or the applicability of this Section 12 to the extent necessary to comply with Section 16(b) of the Securities Exchange Act of 1934, the Internal Revenue Code or any other applicable law or regulation. The grant of an option pursuant to the Plan shall not limit 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, exchange or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

SECTION 12.
SECURITIES LAW COMPLIANCE

    No shares of Common Stock shall be issued pursuant to the Plan unless and until there has been compliance, in the opinion of Company's counsel, with all applicable legal requirements, including without limitation, those relating to securities laws and stock exchange listing requirements. As a condition to the issuance of Option Stock to Optionee, the Administrator may require Optionee to (i) represent that the shares of Option Stock are being acquired for investment and not resale and to make such other representations as the Administrator shall deem necessary or appropriate to qualify the issuance of the shares as exempt from the Securities Act of 1933 and any other applicable securities laws, and (ii) represent that Optionee shall not dispose of the shares of Option Stock in violation of the Securities Act of 1933 or any other applicable securities laws.

5

    As a further condition to the grant of any nonqualified stock option or the issuance of Option Stock to Optionee, Optionee agrees to the following:

    (a) In the event the Company advises Optionee that it plans an underwritten public offering of its Common Stock in compliance with the Securities Act of 1933, as amended, and the underwriter(s) seek to impose restrictions under which certain shareholders may not sell or contract to sell or grant any option to buy or otherwise dispose of part or all of their stock purchase rights of the underlying Common Stock, Optionee will not, for a period not to exceed 180 days from the prospectus, sell or contract to sell or grant an option to buy or otherwise dispose of any nonqualified stock option granted to Optionee pursuant to the Plan or any of the underlying shares of Common Stock without the prior written consent of the underwriter(s) or its representative(s).

    (b) In the event the Company makes any public offering of its securities and determines in its sole discretion that it is necessary to reduce the number of issued but unexercised stock purchase rights so as to comply with any states securities or Blue Sky law limitations with respect thereto, the Board of Directors of the Company shall have the right (i) to accelerate the exercisability of any nonqualified stock option and the date on which such option must be exercised, provided that the Company gives Optionee prior written notice of such acceleration, and (ii) to cancel any options or portions thereof which Optionee does not exercise prior to or contemporaneously with such public offering.

    (c) In the event of a transaction (as defined in Section 12 of the Plan) which is treated as a "pooling of interests" under generally accepted accounting principles, Optionee will comply with Rule 145 of the Securities Act of 1933 and any other restrictions imposed under other applicable legal or accounting principles if Optionee is an "affiliate" (as defined in such applicable legal and accounting principles) at the time of the transaction, and Optionee will execute any documents necessary to ensure compliance with such rules.

    The Company reserves the right to place a legend on any stock certificate issued upon exercise of an option granted pursuant to the Plan to assure compliance with this Section 12.

SECTION 13.
RIGHTS AS A SHAREHOLDER

    An Optionee (or the Optionee's successor or successors) shall have no rights as a shareholder with respect to any shares covered by an option until the date of the issuance of a stock certificate evidencing such shares. No adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property), distributions or other rights for which the record date is prior to the date such stock certificate is actually issued (except as otherwise provided in Section 11 of the Plan).

SECTION 14.
AMENDMENT OF THE PLAN

    The Board may from time to time, insofar as permitted by law, suspend or discontinue the Plan or revise or amend it in any respect; provided, however, that no such revision or amendment, except as is authorized in Section 11, shall impair the terms and conditions of any option which is outstanding on the date of such revision or amendment to the material detriment of the Optionee without the consent of the Optionee. Notwithstanding the foregoing, no such revision or amendment shall (i) materially increase the number of shares subject to the Plan except as provided in Section 11 hereof, (ii) change the designation of the class of employees eligible to receive options, (iii) decrease the price at which options may be granted, or (iv) materially increase the benefits accruing to Optionees under the Plan

6

without the approval of the shareholders of the Company but only if such approval is required for compliance with the requirements of any applicable law or regulation.

SECTION 15.
NO OBLIGATION TO EXERCISE OPTION

    The granting of an option shall impose no obligation upon the Optionee to exercise such option. Further, the granting of an option hereunder shall not impose upon the Company or any Subsidiary any obligation to retain the Optionee in its employ for any period.
