Article
2:Purpose of Alliance

The
purpose of the Alliance is to combine the EarthShell Technology and DuPont expertise in Materials, development, manufacturing and marketing to offer environmentally preferred
packaging and systems to the global marketplace ("Purpose"). The Parties shall work together to identify EarthShell Technology that has potential market application for DuPont. Identified
opportunities will be pursued through cooperative arrangements (each a "Project"). To advise on possible opportunities and to handle other matters arising during the Alliance, an Alliance Advisory
Board ("AAB") will be formed. It is the intent of the Parties that in Projects selected under this Alliance, the use of DuPont Materials will be maximized in EarthShell Technology for the Purpose and
DuPont will include EarthShell Technology in marketing of packaging for the Purpose.

Article
3:Alliance Advisory Board

a.    The
AAB will be composed of two DuPont representatives and two EarthShell representatives to advise the Parties and conduct the Alliance. Within thirty (30) days of the
Effective Date, the Parties will identify in writing their representatives, who will either be employees or agents of that Party and
who will remain representatives of the AAB until the party appointing them replaces any of its representatives with any other representative.

b.    The
AAB shall have a Chairman to serve for one calendar year. The Chairman shall be alternately selected by each Party, commencing in year one with DuPont and in year two
with EarthShell, etc. The Chairman shall conduct all meetings of the AAB. All decisions of the AAB will be by majority vote with respect to any Alliance advisory decision.

c.    The
AAB will meet periodically as needed but at least every six months to review EarthShell Technology, review Projects, select new Projects, consider any Alliance issues
and to review progress of the Alliance. The AAB will hold annual business reviews for key managers of the Parties to discuss and assess performance, future directions and other key issues of the
Alliance.

d.    Each
Party shall have an AAB Sponsor. Within thirty days of the Effective Date of this Alliance Agreement, the Parties will identify in writing their Sponsor, who can be
replaced at that Party's discretion upon written notice to the other Party. In the event any AAB vote is evenly split, the AAB Sponsors shall resolve the matter within thirty (30) days of such split
vote; provided, however, that if the AAB Sponsors are unable to agree, the DuPont President, Packaging and Industrial Polymers and the Chairman of EarthShell shall resolve the matter within thirty
(30) days of the date the AAB Sponsors determine they are unable to agree. In the event the Parties are unable to agree on a Material Issue as hereinafter-defined in Article 8b(3), within the
foregoing time frames, either Party may dissolve the Alliance upon thirty (30) days prior written notice to the other Party.

Article
4:Alliance Projects

a.    Upon
identification of a Project by the AAB, the AAB will prepare the Project Addendum, which shall contain the key parameters for the Project and shall become an exhibit
to this Agreement. Each Project shall have a separate Project Addendum. The AAB will designate a team of employees from each Party to use the Project Addendum to negotiate the agreements to implement
each Project (collectively the "Supplemental Agreements") The Supplemental Agreements may include, at the

2

option of the Parties, a Technology License Agreement, Trademark Agreement and Development Agreement.

b.    The
Project Addendum shall describe the manufacturing, marketing and distribution arrangements, and the branding for products of the Project, the extent that the
EarthShell Technology is to be exclusively or non-exclusively licensed to DuPont for the Project, the terms upon which royalties are payable for use of the EarthShell Technology arising from sales of
products and the scope of additional research or product development for the Project. For each Project, each Party shall bear all costs it
incurs in furtherance of the Project unless otherwise expressly specified in the Supplemental Agreement.

c.    For
each Project, the Parties will appoint a lead company and the designated lead company ("Project Leader") shall have full business authority for all Project decisions
except to the extent specifically identified in a Supplemental Agreement. The Project Leader will be designated in the Project Addendum for the Project.

d.    For
each Project and subject to the terms of the Supplemental Agreements for such Project, each Party will be given the right to continue a Project in the event the other
Party elects to terminate or withdraw from the Project for reasons other than failure of performance to the extent commercially feasible or breach of a Supplemental Agreement for such Project.

e.    Prior
to the Effective Date, the Parties identified two Projects for initial pursuit under this Alliance. The first Project is for the development, commercialization and
sale of biodegradable foodservice wraps ("Food Service Wraps Project") and extendable applications. The Project Leader for this Food Service Wraps Project is DuPont. The second Project is for the
development, commercialization and sale of environmentally preferred disposable foamed laminate packaging bowls, plates, cups, "clamshells", etc. ("Foamed/Laminated Products Project"). The Project
Leader for this Foamed/Laminated Products Project is EarthShell. The Project Addendum for the Food Service Wraps Project is attached and is deemed a part hereof. The Project Addendum for the
Foamed/Laminated Products Project shall be completed and attached to this Alliance Agreement within thirty days of the Effective Date. The Parties will use all commercially reasonable efforts to
complete the Supplemental Agreements for the first two Projects after execution of this Alliance Agreement and thereafter each Project selected during the term of this Alliance Agreement.
