<PAGE>


      6.2 OPTIONS. The Board has the authority to grant Awards of Options to
      Participants with the following terms and condition and with such
      additional terms and conditions not inconsistent with the provisions of
      the Plan as the Board shall determine:

      (a)   Exercise Price. The purchase price for a share of Stock subject to
            an Option granted hereunder shall be not less that 100% of the Fair
            Market Value of the Stock. Notwithstanding the foregoing, in the
            case of an Incentive Stock Option granted to any participant then
            owning more than 10% of the voting power of all classed of the
            Company's stock, the purchase price per share of the Stock subject
            to such Option shall not be less than 110% of the fair market value
            of the Stock on the date of grant of the Incentive Stock Option,
            determined as provided above.

      (b)   Option Term. An Incentive Stock Option Award shall be exercisable
            for a period of 10 years from the date of the grant thereof and NQSQ
            Awards shall be exercisable for a period of 10 years and 1 day from
            the date of the grant thereof.

      (c)   Time and Method of Exercise. An Option may be exercise, in whole or
            in part, and shall be exercised by the Participant delivering a
            written notice of exercise to the Board and paying to the company
            the full purchase price of the shares acquired upon exercise of the
            Option or any portion thereof. No Option shall be exercisable until
            the Plan is approved by the Shareholders of the Company, and as
            provided in Section 14 hereof.

            The full purchase price of each share of Stock purchased upon the
            exercise of an Option shall be paid:

            (i)   in United States dollars in cash or by check, bank draft or
                  money order payable to the order of the Company; or

            (ii)  at the discretion of the Board, through the delivery of shares
                  of Stock, having initially or as a result of successive
                  exchanges of shares, an aggregate fair market value (as
                  determined in the manner provided under this Plan) equal to
                  the Option price;

            (iii) by a combination of both (a) and (b) above;

      provided, however, that the benefit received by a Participant upon
      exercise of an Option for which payment has been made in whole or in part
      by delivery of shares of Stock shall not exceed the spread inherent in
      such Option. For purposes of this Paragraph 7, the "spread inherent" in
      such Option shall equal the difference between the aggregate exercise
      price of the Option and the fair market value of the shares of Stock
      acquired upon the exercise of such Option.



<PAGE>


            The Board shall determine acceptable methods for tendering Stock as
            payment upon exercise of an Option and may impose such additional
            limitations and prohibitions on the use of Stock as a payment upon
            the exercise of an Option as it deems appropriate.

      (d)   Limits. The aggregate fair market value (determined as of the date
            of the Option grant) of all Incentive Stock Options granted under
            the Plan to any Optionee in any calendar year shall not exceed
            $100,000, except to the extent of any unused carryover amount as
            permitted under Section 422A(b) (8) and Section 422A(c) (4) of the
            Code.

            In addition to any other limitations or conditions that may be
            established by the Board with respect to an Incentive Stock Option
            granted under the Plan, no Incentive Stock Option granted pursuant
            to the Plan, no Incentive Stock Option granted pursuant to the Plan
            to any employee then owning more than 10% of the voting power of all
            classes of the Company's stock may be exercised by its terms after
            the expiration of five years from the date of the grant thereof, nor
            may an Incentive Stock Option that may be granted to an Optionee be
            the Company under this Plan or any other stock option plan of the
            Company ( or of any corporation that is a parent or subsidiary of
            the Company or a predecessor corporation of any of the foregoing) is
            "outstanding" within the meaning of Section 422A(c) (7) of the Code.
            Until certificates for the shares acquired upon the exercise of an
            Option are issued to a Participant, such Participant shall not have
            any rights of a shareholder.

6.3 RESTRICTED STOCK. The Board has the authority to grant Awards of Restricted
Stock to Participants with the following terms and conditions and with such
additional terms and conditions not inconsistent with the provisions of the Plan
as the Board shall determine:

      (a)   Restrictions. Shares of Restricted Stock shall be subject to such
            restrictions as the Board may impose, including and without
            limitation, any limitation on the right to vote a share of
            Restricted Stock or the right to receive any dividend or other right
            or property with respect thereto, which restrictions may lapse
            separately or in combination at such time or times, in such
            installments or otherwise as the Board may deem appropriate.

      (b)   Stock Certificates. Any Restricted Stock granted under the Plan
            shall be evidenced by issuance of a stock certificate or
            certificates, which certificate or certificates shall be held by the
            Company. Such certificate or certificates shall be registered in the
            name of the Participant and shall bear an appropriate legend
            referring to the terms, conditions, and restrictions applicable to
            such Restricted Stock.

<PAGE>


      (c)   Forfeiture. Except as otherwise determined by the Board, upon
            termination of employment during the applicable restriction period,
            all shares of Restricted Stock at such time subject to restrictions
            shall be forfeited and reacquired by the Company. However, the Board
            may, when it determines a waiver of the restrictions may be in the
            best interest of the Company, waive in whole or in part any or all
            of the remaining restrictions with respect to Restricted Stock, at
            the sole discretion of the Board.

      (d)   Delivery of Shares. Any share representing Restricted Stock that is
            no longer subject to restrictions shall be delivered to the holder
            promptly after the applicable restrictions lapse or are waived.

7.    AWARD AGREEMENTS

      Upon the grant of an Award under the Plan, the Participant shall enter

which the Award is so granted pursuant to the Plan and containing such other
terms with respect to the Award as the Board in its sole discretion may
determine.

Plan, the Company shall require that a Participant agree with and represent to
the Company in writing that he or she is acquiring such shares of Stock for the
purpose of investment and with no present intention to transfer, sell or
otherwise dispose of such shares of stock other than by transfers which may
occur by will or the laws of descent and distribution. No shares of Stock may be
transferred unless, in the opinion of counsel to Company, such transfer shall at
such time be in compliance with applicable securities laws. In addition, unless
a registration statement under the Securities Act of 1933 is in effect with
respect to the Stock to be purchased under the Plan, each certificate
representing any shares of Stock issued to a Participant hereunder shall have
the endorsed thereon legends in substantially the following form:

REGISTRATION UNDER THE SECURITIES ACT OF 1933 AS AMENDED (THE "ACT) AND WITHOUT
REGISTRATION UNDER ANY APPLICABLE STATE SECURITIES LAWS, IN RELIANCE UPON
EXEMPTION(S) CONTAINED THEREIN. NO TRANSFER OF THESE SHARES OR ANY INTEREST
THEREIN MAY BE MADE EXCEPT PURSUANT TO EFFECTIVE REGISTRATION STATEMENTS UNDER
SAID LAWS UNLESS THE CORPORATION HAS RECEIVED AN OPINION OF LEGAL COUNSEL
SATISFACTORY TO IT THAT SUCH TRANSFER OR DISPOSITION DOES NOT REQUIRE
REGISTRATION UNDER SAID LAWS AND, FOR ANY SALES UNDER RULE 144 OR THE ACT, SUCH
EVIDENCE AS IT SHALL REQUEST FOR COMPLIANCE WITH THAT RULE, OR APPLICABLE STATE
SECURITIES LAWS."

      Plan shall be exercisable during the Participant's lifetime only by the
      Participant.

10.   TERMINATION OF EMPLOYMENT

      10.1 GENERALLY.Except as otherwise provided in this Section 10, if the
employment of a Participant with the Company should be terminated (hereinafter

the Participant's Termination of Employment, exercise an Option granted under
the Plan, but only to the extent the Participant was entitled to exercise the
Option at the Date of Termination of Employment and only if the term of the
Option has not expired. The exercise of an Option under this Section shall
deemed to have occurred one (1) day prior to the date of Termination of
Employment. All shares of Restricted Stock granted to a Participant in which any
restrictions have not lapsed at the Date of Termination shall be forfeited.

      10.2 DEATH OR DISABILITY OF PARTICIPANT. In the event of death or
Disability of a Participant prior to the expiration of an Option held by him or
her:

      10.2.1 If the Participant is at the time of his or her death or Disability
      employed by the Company and has been in continuous employment (as
      determined by the Board in its sole discretion) since the date of the
      Grant of the Option, then the Option may be exercised: (i) in the case of
      Disability, by the Participant within ninety (90) days following the date
      of such Disability, but only to the extent the Participant was entitled to
      exercise such Option at the time of his or her Disability; or (ii) in the
      case of death, by the Participant's estate, or by a person who acquired

      distribution within ninety (90) days from the date of the Participant's
      death, but only to the extent the Participant was entitled to exercise the
      Option at the time of death. For the purpose of this Section, the term
      "Disability" shall have meaning given to it in Section 105 (d) (4) of the
      Code. The Disability of a Participant within the meaning of Section 105(d)
      (4) shall be determined by the Board, in its sole discretion.

      Termination of Employment, the option may be exercised at any time within
      six months following the date of death, by the Participant's estate or by
      a person who acquired the right to exercise the Option by will or the laws
      of descent or distribution but only to the extent the Participant was
      entitled to exercise the Option at the time of Termination of Employment.

at any time, and from time to time, suspend or terminate the Plan in whole or in
part or amend it from time to time in such respects as may be in the best
interests of the Company, provided, however, that no such amendment shall be

liability, or claim under the Plan, except as provided herein or in any Award
agreement.

written election to have shares of Stock withheld by the Company from the shares
otherwise to be received. The number of shares so withheld shall have an
