                                             pursuant to a request for

            Supplementary Agreement to the OEM Manufacturing Contract

                                     Between
   Shandong Xiaoya Group Company Limited (hereinafter referred to as "Xiaoya")
                                       And
      TurboChef Technologies Inc. (hereinafter referred to as "TurboChef")

After friendly negotiations, both Xiaoya and TurboChef enter into the following
supplementary agreement which will be regarded as the legal supplement and
amendment for the OEM manufacturing contract that was signed by both parties on
May 19/th/, 2000.

1)   From Apr. 2002 to Aug. 2003, Turbochef agrees to purchase ++ additional
     units of TurboChef C3 commercial countertop ovens (hereinafter referred to
     as "C3 oven" or "C3 ovens") from Xiaoya as per the attached Schedule B.
     Both parties may agree to amend the production schedule under mutually
     acceptable terms and conditions. The FOB QINGDAO, CHINA unit price for the
     first ++ C3 ovens (single phase US or single phase UK) is agreed by both
     parties to be ++ USDollars/unit, and the FOB QINGDAO, CHINA unit price for
     next ++ C3 ovens (single phase US or single phase UK) is agreed to be ++
     USDollars/unit. The unit price of a three phase oven shall be ++
     USDollars/unit greater than the single phase unit price, as agreed to
     above.
2)   As per agreement, Xiaoya is responsible for purchasing parts and components
     for C3 oven. However, TurboChef is responsible for purchasing and shipping
     parts to China that are only available in USA, which is called USA sourced
     parts and components. The price for USA sourced parts and components is CIF
     JINAN, CHINA price. The list and price for USA sourced parts and components
     are listed on the BOM (Schedule A). Each time TurboChef brings USA sourced
     parts and components from USA a meeting should be held between Xiaoya and
     TurboChef to review the list and make any changes to the items listed,
     prices and shipping costs. Invoices will be provided by both parties if
     required. As both TurboChef and Xiaoya desire to purchase all components
     from China/Asia sources, the goal is that Xiaoya will eventually source all
     USA sourced parts and components. Any USA parts and components sourced by
     Xiaoya and approved by TurboChef that cost less than USA BOM prices, Xiaoya
     has the right to keep the savings. Prior to purchasing any parts on
     TurboChef's behalf, Xiaoya will first utilize all the parts already
     purchased by TurboChef.
3)   TurboChef will TT full price less cost of USA sourced parts and components
     to Xiaoya before shipment in lots, then Xiaoya will effect the shipments.
4)   TurboChef will supply 3 phase purchasing parts to Xiaoya during the course
     of this agreement.
