Mr. Simon K. Hodson
EarthShell Container Corporation
800 Miramonte Drive
Santa Barbara, CA 93109-1419

Finally we have reached a point where most of the problems and issues 
surrounding your development -- and our introduction -- of EarthShell 
packaging are behind us. To summarize where we are in simple terms, and to 
avoid as much legalese as possible, I'd like to confirm the following: As 
soon as price can be agreed upon, I will recommend to the McDonald's Senior 
Management that we authorize the purchase of EarthShell sandwich containers 
(the "Containers") for a single menu item for all McDonald's restaurants in 
the United States for at least a three-year period.

The responsibility to accept and pay for product thereafter, or to continue 
to accept and pay for product, however, shall be expressly subject to the 
following terms and conditions:(1)

                           TERMS AND CONDITIONS

1.  The Containers will meet and maintain all product specifications 
    established by McDonald's which specifications may be amended from time 
    to time by McDonald's in its reasonable discretion. (Initial 
    specifications are attached to this letter as Exhibit A which are subject 
    to Paragraph 9 hereof.) Where a change in specifications requires or 
    justifies an adjustment in the price of the containers, either upwards or 
    downward, all parties will use their best efforts to negotiate or 
    facilitate such an adjustment directly through their agents, licensees, 
    converters, or affiliates.

2.  McDonald's shall receive such assurances and documentation as is 
    reasonably required in order to ensure that the use of EarthShell 
    Containers shall not violate or infringe the patent or other intellectual 
    or proprietary rights of others.

3.  EarthShell and/or its licensed converters supplying McDonald's with 
    EarthShell Containers ("licensed converters") shall demonstrate their 
    ability to manufacture and have ready for use an adequate ongoing supply 
    of the Containers in order to meet the quantity and quality requirements 
    of the intended purchase order.


-----------------------------
(1) Even though we are very encouraged by the product we have tested, these 
terms and conditions are necessitated by the fact that the product has not 
yet actually been manufactured on the same equipment that would be needed to 
meet our quantity requirements.


<PAGE>

4.  Any environmental claims made from time to time by EarthShell, its 
    subsidiaries, affiliates and licensed converters shall be appropriate, 
    properly supported, and in compliance with all applicable guidelines as 
    respects the Containers.

5.  The price of EarthShell Containers sold to the McDonald's system shall 
    not exceed the price charges to any third party by EarthShell or any 
    of its licensed converters for a comparable EarthShell Container taking 
    into account product specifications, quantities ordered, delivery terms, 
    etc.

6.  The Containers are favorably received and continue to be favorably 
    received by McDonald's franchisees and McDonald's restaurant customers 
    as determined in McDonald's reasonable discretion.

7.  EarthShell, its officers, directors, employees and affiliates shall not 
    engage in any act, or the Containers shall not have any environmental or 
    other characteristics, (whether actual or perceived) which, in McDonald's 
    reasonable discretion, could adversely affect the McDonald's brand or 
    McDonald's System.

8.  Neither EarthShell nor its licensed converters shall be in default of any 
    contractual obligations to Perseco or any other McDonald's supplier in 
    connection with the Containers which are the subject of this letter.

9.  In the event that any term or condition contained in this letter is not 
    met, EarthShell or its licensed converter shall have a reasonable time 
    to cure the problem or otherwise restore the product to compliance with 
    the terms and conditions, subject to the following:

        A.  If the terms and conditions are not met within 24 months of the 
        date of this letter, neither McDonald's nor Perseco shall have further 
        obligations to purchase or authorize purchase of the Containers, and

        B.  Once Containers are in use in McDonald's restaurants, a failure in 
        any terms or conditions may require that existing inventories be 
        discarded and replaced with alternative packaging provided by third 
        parties. (In other words, the restaurants cannot be expected to use 
        defective or otherwise non-compliant Containers.)

10. EarthShell and its licensed converters acknowledge and agree that 
    McDonald's continuously investigates ways to improve its operations, that 
    McDonald's is generally engaged in a wide variety of research and 
    investment opportunities in a broad array of areas, and that McDonald's 
    may be working with, investigating or reviewing other or similar products, 
    concepts and/or technologies with other entities. EarthShell and its 
    licensed converters expressly acknowledge and agree that such activities 
    on the part of McDonald's do not breach the terms and conditions set out 
    in this letter and that McDonald's has no obligation to disclose its 
    involvement in such activities to EarthShell. Furthermore, EarthShell and 
    its licensed converters acknowledge and agree that McDonald's will at all 
    times, be free to investigate and utilize alternate sources of sandwich 
    containers.


<PAGE>

11.  EarthShell and its licensed converters will continuously improve upon 
     the environmental impacts of the Containers provided to Perseco with a 
     long-term goal of reducing the key environmental loadings by 40% from 
     the April 18, 1997 LCI submitted by Franklin Associates for the QPC 
     sandwich container.

12.  EarthShell's licensed converters agree that if they believe that the 
     production and sale of Containers in accordance with any McDonald's 
     specifications will result in such Containers not being in compliance 
     with all applicable laws, rules, regulations, and local codes, or that 
     the Containers will infringe any patent or other proprietary right of a 
     third party, then EarthShell's licensed converters will immediately 
     notify McDonald's and provide to McDonald's all relevant information 
     concerning such belief. EarthShell and its licensed converters 
     acknowledge and agree that McDonald's is looking to EarthShell and its 
     licensed converters to advise it of the aspects of the McDonald's 
     specifications that should be changed and of EarthShell and/or its 
     licensed converters recommended changes so that the Containers will be 
     in compliance with such codes, regulations and laws and not infringe any 
     patent or other proprietary right of a third party. McDonald's, in its 
     sole discretion, shall determine whether or not to accept the 
     specification changes recommended by EarthShell and/or its licensed 
     converters.

13.  EarthShell and its licensed converters acknowledge that McDonald's does 
     not directly operate any McDonald's restaurants and will not purchase 
     any Containers from EarthShell and its licensed converters. EarthShell 
     and its licensed converters acknowledge and agree that orders for 
     Containers will come only from Perseco or the approved independent 
     distribution centers and that Containers will be used only by McDonald's 
     restaurants owned by independent franchisees or McDonald's subsidiary 
     corporations, referred to as McOpCo's, and other approved parties 
     ordering directly from EarthShell's licensed converters. EarthShell and 
     its licensed converters acknowledge and agree that McDonald's is not 
     making any promises, commitments or guarantees of sales.

14.  EarthShell and its licensed converters acknowledge and agree that the 
     only contractual obligations involved in this contemplated business 
     relationship for the purchase of Containers arise from orders placed by 
     McDonald's independent distribution centers (through Perseco) and 
     approved by McDonald's for sale to McDonald's restaurants. These parties 
     decide whether to order from EarthShell's licensed converters and their 
     obligations are limited to payment for items delivered in conformity 
     with their orders. McDonald's is not responsible for and does not 
     guarantee payment of any invoices or accounts (whether past due, 
     delinquent or otherwise) from anyone ordering from EarthShell's licensed 
     converters and those parties ordering from EarthShell's licensed 
     converters are solely responsible for payment.

15.  EarthShell and its licensed converters agree to indemnify McDonald's 
     its subsidiaries, suppliers and franchisees from any and all claims, 
     damages, expenses and lawsuits caused by the Containers which are not 
     attributable to McDonald's, its affiliates, subsidiaries, suppliers or 
     franchisees, including, without limitation, infringement of any patent 
     or any other proprietary right or trade secret misappropriation or 
     unfair competition claims. EarthShell and its licensed converters


<PAGE>

     agree to maintain comprehensive general liability insurance in an amount 
     and with a carrier having a financial rating approved by McDonald's to list
     McDonald's as an additional named insured, as its interests may appear, 
     and to provide McDonald's upon request with proof of such insurance. 
     Liability under this paragraph however, shall not be limited by the 
     amount of insurance carried. The parties will use their best efforts to 
     minimize and negotiate such claims to the extent possible.

16.  EarthShell and its licensed converters' authority to use any McDonald's 
     trademark is limited to the usage designated by McDonald's in writing 
     and is subject to termination by McDonald's with or without cause at any 
     time. In addition, EarthShell and its licensed converters are prohibited 
     from adding the "Mc" or "Mac" prefixes to any items unless EarthShell 
     and its licensed converters secure McDonald's prior written approval.

17.  Except as required by law, EarthShell and its licensed converters are 
     not authorized to make any public announcements that it or they are an 
     approved McDonald's supplier or that the Containers are approved by 
     McDonald's unless EarthShell and its licensed converters first receive 
     express written permission from McDonald's to make that disclosure.

18.  The EarthShell logo and/or other identifying marks shall not be 
     displayed on the Containers except in a manner to which McDonald's 
     agrees, which agreement shall not be unreasonably withheld.

19.  This letter sets forth the understanding of the parties regarding 
     McDonald's approval of the purchase of Containers and to the extent 
     inconsistent therewith supersedes all prior written and oral agreements 
     and understandings regarding the same.

20.  This letter is not intended to be an enforceable agreement and is subject 
     to the negotiation of definitive documentation in accordance with the 
     terms and conditions set forth above.

If the above conforms with your understanding, please let me know so that I 
can make my final recommendation to Senior Management.


Very truly yours,



/s/ Shelby Yastrow

                         PACKAGING CRITERIA FOR SUCCESS

I.   STORE OPERATIONS:
     A.  Package product breakage and operational failure rate must meet 
         allowable target limits:
         1.   Breakage is defined as:
              a)   Damage to the outer case of the container that raises concern
                   about the sanitary and quality nature of the package held 
                   within.
              b)   Damage to the actual package that renders the package 
                   non-functional, such as closure or hinge damage.
              c)   Aesthetic damage to the actual package that renders the 
                   package non-usable as determined solely by the McDonald's 
                   restaurant.
         2.   Allowable and target rates:
              a)   Not to exceed 1% in the McDonald's System;
              b)   Target of 0% to be approached with incremental improvements 
                   in subsequent years of use in the McDonald's System.
         3.   Breakage/failure measurement to include a sum of, but not 
              exclusive to the following:
              a)   Transportation and related distribution handling
              b)   Crew operations and handling
     B.  Package must be functional in all potential 
         McDonald's preparation methods:
     C.  Package must be the appropriate size to contain the specified 
         sandwich while maintaining sandwich integrity and appearance 
         acceptable to McDonald's. The package size must consider the 
         changing operational and product environments at McDonald's.
     D.  Package must be fast and easy to close.
     E.  Package must stay closed, when in the bin for example.
     F.  Package should not be confusing to the crew to use - easy to train 
         the crew.
     G.  Package should perform well in all styles of transfer bins; slide, 
         shelf, stack.
     H.  Package should stack easily in carry-out bags.
     I.  Package must be functional in storage and handling.
         1.   Case size must be appropriate for storage
         2.   Case weight must be appropriate for crew handling (under 40 lbs 
              maximum)
         3.   May need inner sleeves to facilitate crew transportation and 
              storage 


                                       1 of 4

II.  CUSTOMER SATISFACTION:
     Marketability of the package to be used in the McDonald's restaurants 
     needs to perform at least equivalently to the F-flute container (or 
     current incumbent package) for parameters below:
     A.  McDonald's Marketing perspective - meets standards and requirements 
         of appropriate McDonald's Marketing Management. Including such 
         parameters as:
         1.   Base colors
         2.   Ink colors
         3.   Print areas
         4.   Overall appearance of the container
         5.   Promotional vehicle to carry coupons or game pieces
         6.   Graphics changes/printability
         7.   Label application for games
         8.   The graphics need to facilitate, and not limit, the crew's 
              ability to distinctively identify the package for different 
              menu items, including:
              a)   In the grill area when preparing the food
              b)   In the bin when selecting product to present to the 
                   customer
     B.  The package must meet the requirements of McDonald's consumers as 
         measured by and in accordance with McDonald's Market Research group, 
         in areas such as:
         1.   Improvement in food taste ratings, including
              a)   temperature
              b)   moistness
              c)   sensory evaluation
         2.   Overall ease of use
              a)   In-store
              b)   Drive-thru
         3.   Food product appearances
         4.   Package attractiveness
         5.   Ease of differentiating one sandwich package from another
         6.   Perceived environmental impact
         7.   Intent to buy more McDonald's products
     C.  The package must be meet the standards and requirements of 
         McDonald's Test Kitchen, in areas such as:
         1.   Food taste
         2.   Food appearance
         3.   Food temperature

III. ENVIRONMENTAL IMPACT:

     The environmental impact of the any alternative package needs to be, at 
     a minimum, comparable to the environmental impact of the incumbent 
     package. The overall goal of McDonald's and Perseco is to continuously 
     improve the environmental impact of the packaging used in the McDonald's 
     System. Environmental impacts are measured by, but not limited to, life 
     cycle inventories and assessments, expert environmental and scientific 
     input and review, public opinion, media coverage, and McDonald's and 
     Perseco's own assessment.

IV.  PRICE AND AVAILABILITY:

     The delivered price of the alternative package must give McDonald's a
     competitive value gap against their competition, with the value gap 
     determined solely by McDonald's. The delivered price to include FOB 
     (exworks), freight delivered to the restaurant level and breakage 
     allowances.

     A. Delivered cost:

        1. FOB
        2. Freight from supplier to DC
        3. Freight from DC to restaurant
        4. Breakage allowance

     B. The competitive value gap must apply against other competitive new 
        packaging introductions that may occur prior to or during the 
        introduction of the subject alternative package, and thereafter.

     C. The competitive value gap must be sustained throughout any product 
        changes inherent in the McDonald's system, such as, but not limited 
        to:

        1. New food preparation procedures
        2. New menu item formulations, such as bun sizes
        3. New packaging performance expectations

     D. The alternative package must meet all applicable FDA guidelines for 
        food safety. The package must be safe to use for its intended purpose 
        with the consumer in mind.

     E. As the alternative package is introduced to the market, it is 
        McDonald's and Perseco's expectation that the McDonald's System has 
        assured supply. Assured supply means that all orders by the 
        McDonald's distribution centers are filled on time and in full, 
        unless previously agreed upon contingency plans are agreed upon.

     F. As the alternative package manufacturing base needs expansion, 
        McDonald's will make the final decision on which converter and 
        converter location(s) will get additional production volumes. The 
        converter selection is not limited by the initial converter or 
        technology licenser.

                                 3 of 4

<PAGE>

V.   OTHER BUSINESS PARAMETERS:

     A. The alternative package manufacturer and/or licenser of technology 
        shall provide McDonald's with First Right to Refusal:

        1. The option to purchase the First commercial production available 
           for any Quick Service Restaurant (QSR) package developed, by any 
           converter.
        2. Sustaining volumes for McDonald's demand for any QSR package prior 
           to sale of said package to other companies/organizations.

     B. If for any reason the converter fails to meet any of the criteria for 
        success items in this document, McDonald's and Perseco reserves the 
        right to make null and void any and all agreements to purchase 
        subject package, and all liabilities will be the responsibility of 
        the converter(s).

     C. If during the course of commercialization or on-going business the 
        McDonald's food preparation systems or menu item recipes change, 
        McDonald's or Perseco will not be held responsible for any tooling or 
        other production equipment or facilities thereby made obsolete.

                                    4 of 4

McDonald's Corporation
One Kroc Drive
Oak Brook, IL 60521

Dear Shelby:

Thank you for your letter of August 22, 1997 specifying the terms and 
conditions upon which you will recommend to McDonald's Senior Management that 
they approve the purchase of an EarthShell sandwich container for use in all 
of McDonald's domestic restaurants. This letter confirms our acceptance of 
those terms and conditions.

If her schedule permits, I would like to arrange for Claire Babrowski to 
visit our facilities next week in Santa Barbara and to review our products 
and recent technological improvements. Please have her call me at her 
earliest convenience to discuss the scheduling of her visit.

Shelby, this is the most significant event in the Company's history and I am 
very grateful for your past patience, encouragement and support. This 
milestone could not have been achieved without your significant involvement, 
and the support of McDonald's Senior Management. You have my commitment, as 
well as that of the entire EarthShell team, to ensure that EarthShell 
packaging contributes to McDonald's well deserved reputation and success.

Sincerely,
