     "B.  Consideration, Assumption of Certain Liabilities.  In consideration
          -------------------------------------------------                  
for the Assets, Grand Prix and Buyer agree as follows:

     1.   On the Closing Date, Seller will receive from Grand Prix a number of
shares of Grand Prix's Series B voting preferred convertible shares, as
hereinafter described, (the "Preferred Stock"), having an aggregate stated value
of Two Million Five Hundred Thousand and no/100 Dollars ($2,500,000.00), such
value and number of shares to be based upon the offering price per share of the
shares of common stock of Grand Prix offered by Grand Prix to secure financing
for acquisition of the Assets (the "IPO").  The shares of Preferred Stock shall
be convertible at any time and from time to time on and after June 30, 1997 into
shares of Grand Prix's common stock, which will have the same rights,
preferences and privileges as the common stock being issued in the IPO,  (the
"Common Stock") on a 1 share for 1 share basis subject to adjustment to reflect
any and all stock splits, stock dividends, recapitalizations, options issued
allowing for purchase of Common Stock for less than fair market value, or
similar events, so that the Preferred Stock and conversion rights into Common
Stock with 

                                       2

 
respect thereto are not diluted in any manner whatsoever after the Closing Date
and prior to conversion into Common Stock.

          The Preferred Stock will bear an aggregate annual cumulative dividend
rate equal to 4.185% of $2,500,000.00 (calculable and payable on a per share
basis on or before each anniversary of Closing or upon conversion of all
remaining Preferred Stock prior to such anniversary) until the date converted.
Dividends shall cease on the date of conversion, or December 31, 1998 or upon
payment of the unassumed indebtedness of Seller referred to below, whichever
shall be earliest.

          If Seller does not convert any of the Preferred Stock into Common
Stock on or prior to December 31, 1998, then Grand Prix shall, at any time
during the month of January, 1999, call and redeem all of the Preferred Stock at
a $.01 per share redemption price and the Buyer shall assume, pay and indemnify
Seller, its shareholders and their legal representatives and heirs from and
against all unpaid loan indebtedness of Seller not assumed by Buyers at Closing
(as set forth on Exhibit "G" hereto) not to exceed the total sum of One Million
Five Hundred Thousand Dollars ($1,500,000.00). If Seller exercises its right to
convert any of the Preferred Stock, then Buyer shall have no obligation with
respect to such unpaid loan indebtedness of Seller not assumed by Buyer at
Closing. When used herein, the phrase "loan indebtedness of Seller not assumed
by Buyer" or "unassumed indebtedness of Seller" shall mean that part of the
total loan or other indebtednesses of Seller (as the same may be restructured in
accordance with this Agreement), which may fluctuate from time to time in the
ordinary course of Seller's business, which is not assumed by Buyer, and shall
not mean any loan indebtedness of Seller incurred after Closing. Any amendments,
modifications, renewals, extensions or other changes to such unassumed
indebtedness of Seller made after Closing shall be subject to approval by Buyer.
Notwithstanding any other provision of this Agreement to the contrary, Grand
Prix consents to the pledge of the Preferred Stock by Seller as collateral with
respect to such loan indebtedness of Seller not assumed by Buyer.

     2.   Buyer agrees to assume, pay and perform all of Seller's agreements,
duties and obligations (including, but not limited to, the assumption and
payment of $2,500,000.00 of Seller's loan indebtedness) under only those
contracts listed and as provided in Exhibit "E" (the "Assumed Liabilities").  It
is expressly understood and agreed that Buyer shall not be liable for any of the
obligations or liabilities of Seller of any kind and nature other than those
specifically assumed by Buyer under this Agreement."

direction MIMC under this Agreement and that require prosecution or enforcement
in Seller's name. Any such action or prosecution or enforcement of claims,
rights, or benefits under this paragraph shall be solely at Buyer's expense or
at Buyer's direction MIMC's expense, unless the action, prosecution or
enforcement is made necessary by a breach of this Agreement by the Seller."
