      Re:  XXXX/BIOPAC TECHNOLOGY
           ----------------------


Dear Xx. Xxxxxx:

      Reference is made to those certain Patent Purchase Agreements (the 
"Agreements"), dated February 11, 1998, between E. Khashoggi Industries, LLC 
("EKI") and Xxxxx Xxxx Waffelmaschinen Industrie Aktiengesellschaft ("Xxxx 
Austria"), pursuant to which EKI has agreed to purchase certain patents, 
patent applications and know-how owned by Xxxx Austria or its affiliates and 
which relate to biodegradable, non-edible packaging composed primarily of raw 
materials which have a high starch content, as well as their methods of 
production (the "BIOPAC Technology"). Pursuant to the Agreements, EKI is 
required to pay or deliver the following consideration:

      a.  $3 million in cash payable at the closing (the "Closing") of EKI's 
purchase of the BIOPAC Technology (the "$3 Million Cash Consideration");

      b.  A $500,000 letter of credit to be delivered by EKI no later than 
the Closing and which is payable to Xxxx Austria upon the termination of the 
license agreement and representative agreement between Xxxx Austria's 
predecessor and Sumitomo Corporation (the "$500,000 LC");

      c.  A $3.5 million letter of credit to be delivered by EKI at the 
Closing and which is payable to Xxxx Austria on or about December 31, 2003 
(the "Payment Date"), subject, however, to reduction in an amount equal to 5% 
of the purchase price of the equipment and machinery purchased by EKI, 
EarthShell Corporation ("EC") and their respective sublicencees from Xxxx 
Austria or its affiliates prior to the Payment Date (the "$3.5 Million LC"); 
and

      d.  $3 million in cash payable by EKI to Xxxx Austria over a five-year 
period following the Payment Date if EKI, EC or their sublicensees make 
active use of the BIOPAC

Technology and EC and/or EKI fail to purchase at least $3.5 million of Xxxx 
Austria equipment by the Payment Date, (the "$3 Million Obligation"). The $3 
Million Obligation is subject to reduction in an amount equal to 5% of the 
purchase price of Xxxx Austria equipment or machinery ordered by EKI, EC or 
their sublicensees during such extended five-year period.

       This letter will confirm our mutual agreement with respect to the 
following:

       1.   Immediately following the Closing, EKI will license the BIOPAC 
Technology to EC, without additional cost, pursuant to the terms and 
conditions of that certain Amended and Restated License Agreement, dated 
February 28, 1995, between EKI and EC.

       2.   EKI will pay, and be solely responsible for, the $3 Million Cash 
Consideration, the $500,000 LC and any related costs (e.g., the cost of the 
$500,000 LC).

       3.   EC will pay, and be solely responsible for, the $3.5 Million LC, 
the $3 Million Obligation and any related costs (e.g., the cost of the $3.5 
Million LC). In that connection, EC shall be entitled to receive any credits 
or offsets available for the purchase of equipment or machinery from Xxxx 
Austria or its affiliates, including purchases by EKI and its licensees.

       4.   EKI shall pay, and be solely responsible for, all other costs and 
expenses incurred by EKI in connection with the negotiation and execution of 
the Agreements and the performance of EKI's obligations thereunder.

       5.   EKI shall indemnify EC, and hold it harmless against, any portion 
of the $3 Million Obligation which is payable by EC solely as a result of 
EKI's or its licensees' active use of the BIOPAC Technology (other than use 
by EC or its sublicensees).

       6.   Pursuant to the Agreements, EC shall enter into a royalty-free, 
irrevocable license agreement with Xxxx Austria pursuant to which EC shall 
license to Xxxx Austria all proprietary technology necessary to optionize the 
performance of Xxxx Austria's equipment and machinery.
