applicable to such Shares. Such restrictions shall be set forth in the Option
Agreement entered into with each of the Participants.

         6.7 Nontransferability of Options. No Option granted under the Plan may
be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated,

                          ARTICLE 7 PUT AND CALL RIGHTS

         7.1 Sale to the Company by Participants. Any vested options may be sold
to the Company upon the Participant's written notice of demand. The purchase
price per Option share shall be calculated as follows:

(The Company's pre-tax income, determined in accordance with generally accepted
accounting principles consistently applied, for the 12 calendar months preceding
the calendar month in which notice is given x 7.26)
                                   divided by
             Total Shares Outstanding = Purchase Price per option

                    7.2  Call Right by the Company. In the event that a
                         Participant's employment with the Company is terminated
                         for any reason, the Company shall have the right but
                         not the obligation to purchase the Participant's vested
                         Option shares. The calculation of the purchase price
                         per Option share shall be as set forth in paragraph 7.1
                         above.

                    7.3  The foregoing calculations as set forth in and
                         described in paragraphs 7.1 and 7.2 are based upon the
                         assumption that the Company has 1,000,000 Shares issued
                         and outstanding. In the event of any change or
                         adjustment to the number of shares issued and
                         outstanding of the Company, the foregoing formula shall
                         be adjusted ratably.

                       ARTICLE 8 TERMINATION OF EMPLOYMENT

         8.1 Termination by Reason of Death, Disability or Retirement. In the
event the employment of a Participant is terminated by reason of death,
Disability, or Retirement, the following provisions shall apply:

                           (a) Treatment of Stock Options. All outstanding
                           Options granted to the Participant which have vested
                           pursuant to the Vesting Schedule set forth above
                           prior to the date of Participant's termination of
                           employment) (the "Covered Options"), shall not be
                           forfeitable in the event of death or Disability, but
                           shall be forfeitable in the event of Retirement and,
                           if not so forfeitable, shall remain exercisable at
                           any time


                                  Page 4 of 7




<PAGE>



                           prior to their expiration date, or for one
                           (1) year after the date of death, Disability, or
                           Retirement, whichever period is shorter, by the
                           Participant or by such person or persons that have
                           acquired the Participant's rights under the Option by
                           will or by the laws of descent and distribution. The
                           Plan Administrator shall, in all cases, determine the
                           date of employment termination. All Options granted
                           to the Participant pursuant to the Plan other than
                           the Covered Options shall be forfeited and shall once
                           again be available for grant under the Plan.

                           (b) Amounts Subject to Dispute. If at the time of a
                           Participant's death, the Plan Administrator is unable
                           to determine what person, persons or entity is
                           entitled to exercise Options on behalf of the
                           Participant, the Plan Administrator shall not be
                           required to implement any directions to exercise such
                           Options to any such person, persons or entity during
                           the pendency of such dispute. Neither the Plan
                           Administrator, the Committee or the Company shall be
                           responsible for a failure to implement such exercise
                           instructions during the pendency of such dispute,
                           notwithstanding the fact that Options may diminish in
                           value or expire during the pendency of such dispute.

                                    8.2 Disqualifying Termination. In the event
                           that the Company terminates the employment of a
                           Participant as a result of a Disqualifying
                           Termination, a Participant shall forfeit all Unvested
                           Options. Any Covered Options may not be exercised at
                           any time after the expiration of 90 days from the
                           date of termination.

         8.3 Other Termination. In the event a Participant's employment is
terminated for reasons other than death, Disability, Retirement or Disqualifying
Termination,

                           A Participant shall forfeit all unvested Options
                           granted to the Participant under the Plan which do
                           not constitute Covered Options. Covered Options may
                           be exercised by the Participant within the period
                           beginning on the effective date of employment
                           termination, and ending three (3) months after such
                           date.

         8.4 Retirement of Joseph Thomas. In the event of the retirement of
Joseph Thomas, the Committee shall have the right, exercisable at its sole and
absolute discretion, to cause the forfeiture of all unvested Options of each of
the other Participants. In the event the Committee shall exercise this right,
neither it nor the Company shall have any liability or obligation in respect
thereof, except that it shall provide written notice to the Participants
notifying each of them that their Unvested Options have been forfeited.

                        ARTICLE 9 RIGHTS OF PARTICIPANTS

         Nothing in the Plan shall interfere with or limit in any way the right
of the Company to terminate any participating Employee's employment at any time,
nor confer upon any Participant any right to continue in the employ of the
Company.

                          ARTICLE 10. CHANGE IN CONTROL

         If the Board so determines at any time in its discretion, the following
provisions shall apply if a Change in Control occurs after such determination:

                           (a) Any and all Options granted hereunder shall
                           become immediately exercisable (and shall remain
                           exercisable throughout their entire term);

                           Committee to be appropriate before the effective date
