GPSI Shares and GPSI shall instruct the transfer agent to deliver to the Sellers
replacement certificates without any restrictive legend.

sharesYear
      2
              
              5000 shares per
      trading day (per day averaged over a 5 day trading period)Year
      3
              
              5000 shares per
      trading day (per day averaged over a 5 day trading
  period)






2.6           Maximum
Sales.  During the Sales Period the Sellers, except as provided
herein, will not directly or indirectly, without the prior written consent of
GPSI, sell, offer, contract to sell, pledge, grant any option to purchase or
otherwise dispose (collectively, a “Disposition”) the
GPSI Shares (the “Lock-Up Shares”), at
any time during the Sales Period.  The foregoing restriction is
expressly agreed to preclude, among other Dispositions, the holder of the
Lock-Up Shares from engaging in any hedging or other transaction with is
designed to or reasonably expected to lead to or result in a Disposition of
Lock-Up Shares during the Sales Period, even if such Lock-Up Shares would be
disposed of by someone other than such holder.  Such prohibited
hedging or other transactions would include, without limitation, any short sale
(whether or against the box) or any purchase, sale or grant of any right
(including, without limitation, any put or call option) with respect to any
Lock-Up Shares or with respect to any security (other than a broad-based market
basket or index) that includes, relates to or derives any significant part of
its value from the Lock-Up Shares.  Notwithstanding the foregoing,
during the Lock-Up Period, the Sellers shall be permitted to dispose of the
Lock-Up shares as follows: (i) during any three-month period not more than the
2% of the outstanding shares of GPSI’s common stock, and (ii), in any case, not
more than 8% of the daily trading volume on any one particular day using the
average of the previous three trading days.  Notwithstanding the
foregoing, the Sellers my transfer the Lock-Up Shares (i) as a bona fide gift or
gifts, (ii) as a distribution to limited partners or shareholders of such
person; provided, however, that in any
such case it shall be a condition to the transferee execute an agreement stating
that the transferee is receiving and holding the Lock-Up Shares subject to the
provisions of this Settlement Agreement.  Any transferor transferring
pursuant to the subsection (i) or (ii) above shall notify GPSI in writing prior
to the transfer.  During the Sales Period, there shall be no further
transfer of such Lock-Up Shares except in accordance with this
Agreement.





2.7           If
during the Sales Period GPSI’s trading volume is less than 70,000 per day
averaged over a 5 day trading period, then, during such time, Sellers are no
longer required to sell the Minimum Sales as defined in Paragraph
2.5.  If during the Sales Period GPSI’s trading volume is less than
5,000 per day averaged over a 10 day trading period, then the Sellers, acting
jointly, may by written notice to GPSI accelerate the payment of the then
current balance of the Minimum Purchase Price.  GPSI shall pay Sellers
the then current balance of the Minimum Purchase Price within 10 business days
of such written notice.









2.8           Within
twenty business days from the end of the Sales Period, the Sellers, acting
jointly, shall have the option by written notice to GPSI to (a) retain the then
balance, if any, f the GPSI Shares in full satisfaction of all remaining
obligations of GPSI to them with respect to the Minimum Purchase Price or, (b)
return such balance, if any, (the “Remaining Shares”) in
which case, within twenty business days from the receipt of the certificate
evidencing the Remaining Shares, GPSI shall pay to the Sellers the then current
balance of the Minimum Purchase Price, taking into account, since the Effective
Date of this Settlement Agreement, any net proceeds (as defined in the Stock
Purchase Agreement) from the sale of GPSI Shares and any cash payments made to
Sellers by GPSI.  Failure of the Sellers to notify GPSI as to its
election shall be deemed to be an election to retain the GPS
Shares.





2.9           For
avoidance of doubt, GPSI shall have no obligation to register for resale any of
GPSI Shares and GPSI agrees that the GPSI Tradable Shares are now freely
tradable by Sellers.

be replaced with “Prior to Sellers receiving an aggregate cash consideration of
$3,000,000 from either the sale of their Shares and/or from cash payments made
by Purchaser to the Sellers subsequent to the Second Cash Payment,”
