                                   AGREEMENT:

      In consideration for the mutual promises set forth herein and for other
good and valuable consideration, the receipt and legal sufficiency of which are
hereby acknowledged, the Parties hereby agree as follows:

      1. EKI Loan.

         (a) EKI agrees to loan to EarthShell the sum of $350,000 (the "EKI
Loan") by wire transfer of immediately available funds to EarthShell's account
concurrently with EarthShell's execution and delivery of this Agreement and the
execution and issuance in favor of EKI of the EKI Loan Note and the WN Advance
Note (as such terms are defined below).

         (b) The obligation to pay the EKI Loan will be evidenced by a
promissory note in the form of Exhibit A hereto (the "EKI Loan Note") that will
be executed and delivered by EarthShell concurrently with the execution and
delivery of this Agreement. Interest and principal shall be paid by EarthShell
to EKI as provided in the EKI Loan Note. EarthShell agrees to pay, when due, all
amounts owing under the EKI Loan Note, without offset, counterclaim or other
deduction of any kind.

      2. WN Advance. EKI has funded the WN Advance directly to WN for the
account of EarthShell. The obligation to repay the WN Advance shall be evidenced
by a promissory note in the form of Exhibit B hereto (the "WN Advance Note")
that will be executed and delivered by EarthShell concurrently with the
execution and delivery of this Agreement. Interest and principal shall be paid
by EarthShell to EKI as provided in the WN Advance Note. EarthShell agrees to
pay, when due, all amounts owing under the WN Advance Note, without offset,
counterclaim or other deduction of any kind. EarthShell agrees that it will
continue to pay, for the one year period following the date of this Agreement,
all patent and related costs due under the Patent Cost Allocation Agreement
(which costs have been estimated by EKI to be approximately $15,000), with
respect to maintenance of the paper sheet patents in the jurisdictions that they
are currently maintained.

      3. EKI Assurances Regarding Intercompany Agreements. EKI agrees that it
will continue to provide, upon request by EarthShell, written assurances to
prospective sublicensees, lenders and investors as to the status and validity of
the License Agreement and as to the absence of EarthShell's current and existing
defaults which have continued beyond any applicable cure period under any of the
Intercompany Agreements. EKI shall also continue to provide such assurances as
any sublicensee of EarthShell may reasonably request concerning EKI's
willingness to recognize the continuing effectiveness of any sublicenses validly
granted under the License Agreement in the event the License Agreement is
terminated (such assurances to be similar in scope and content to the assurances
previously given by EKI to EarthShell's licensees).

      4. Release.


                                       2
<PAGE>

         (a) Release by EarthShell. EarthShell hereby fully, finally, and
forever releases, quit claims, and discharges EKI and each of its officers,
directors, managers, members, agents, servants, employees, attorneys, affiliated
and subsidiary entities, successors, predecessors and assigns, past and present
(collectively, the "EKI Released Parties") from any and all claims, liabilities,
demands, debts, accounts, obligations, actions, and causes of action ("Claims"),
known or unknown, at law or in equity, of whatever character in any way that
EarthShell may have against EKI or any other of the EKI Released Parties,
through the date of this Agreement, that arise out of, relate to, or otherwise
concern the License Agreement (including any sublicense agreements entered into
by EarthShell thereunder), the Patent Cost Allocation Agreement, the Services
Agreement, the Amended Services Agreement, the Debt Conversion Agreement or any
other Intercompany Agreement or any other agreement or arrangement between the
Parties (whether exclusively or with other parties) relating to financing
transactions, licensing or sublicensing transactions, the provision of services
or any other commercial arrangement (collectively, the "EKI Released Matters"),
excluding, however, any and all Claims pursuant to this Agreement (the "Excluded
Matters"). The EKI Released Matters expressly include, but are not limited to,
any claims for indemnity, contribution, subrogation, or other similar principal
of recovery that EarthShell may have against EKI with regard to the EKI Released
Matters now or in the future, and they also include any matters arising from or
related to any allegation that an EKI Released Party who served both as an
officer, director or owner of EarthShell and EKI had a conflict in making
decisions under the Intercompany Agreements. EKI Released Matters shall not
include any claims which may be asserted by EarthShell as a counterclaim in any
action initiated by EKI or its assigns or any indemnity, contribution, or
reimbursement claim by EarthShell against EKI arising out a claim brought by a
third party against both EarthShell and EKI (provided that, to the extent any
such claim arises under or relates to an Intercompany Agreement, the terms of
such Intercompany Agreement shall govern EKI's and EarthShell's respective
rights and responsibilities with regard to the resolution of such claim).
Notwithstanding the foregoing, any counterclaim that EarthShell is permitted to
bring against EKI pursuant to the immediately preceding sentence may be asserted
by EarthShell only to the extent necessary to reduce or limit EarthShell's
liability to EKI with respect to the claims asserted by EKI in the relevant
action initiated by EKI and in no event shall EarthShell assert any such
counterclaim or enforce any judgment obtained in connection therewith in any
manner that, directly or indirectly, results in EKI incurring a liability that
EKI is required to pay or satisfy. For purposes of this Section 4(a), a third
party claim would not include claims asserted by an officer, director, employee
or shareholder of EarthShell in their capacity as such. The release given by
EarthShell pursuant to this Section 4(a) supplements and shall not in any way
limit the release previously given by EarthShell to EKI pursuant to the terms of
the Debt Conversion Agreement.

         (b) Release by EKI. EKI hereby fully, finally, and forever releases,
quit claims, and discharges EarthShell and each of its officers, directors,
agents, servants, employees, attorneys, affiliated and subsidiary entities,
successors, predecessors and assigns, past and present (collectively, the
"EarthShell Released Parties") from any and all Claims, known or unknown, at law
or in equity, of whatever character in any way that EarthShell may have against
EarthShell or any other of the EarthShell Released Parties, through the date of
this Agreement, that arise out of, relate to, or otherwise concern the License
Agreement (including any sublicense agreements entered into by EarthShell
thereunder), the Patent Cost Allocation Agreement, the Services Agreement, the
Amended Services Agreement, the Debt Conversion Agreement or any other
Intercompany Agreement or any other agreement or arrangement between the Parties
(whether exclusively or with other parties) relating to financing transactions,
licensing or sublicensing transactions, the provision of services or any other
commercial arrangement, including any Claims against any EarthShell Released
Party that arise out of, relate to, or otherwise concern actions taken or
omitted to be taken by any EarthShell Released Party in such EarthShell Released
Party's capacity as an officer or director of EKI (collectively, the "EarthShell
Released Matters"), excluding, however, the Excluded Matters. The EarthShell
Released Matters expressly include, but are not limited to, any claims for
indemnity, contribution, subrogation, or other similar principal of recovery
that EKI may have against EarthShell with regard to the EarthShell Released
Matters now or in the future. EarthShell Released Matters shall not include any
claims which may be asserted by EKI as a counterclaim in any action initiated by
EarthShell or its assigns or any indemnity, contribution, or reimbursement claim
by EKI against EarthShell arising out a claim brought by a third party against
both EarthShell and EKI (provided that, to the extent any such claim arises
under or relates to an Intercompany Agreement, the terms of such Intercompany
Agreement shall govern EKI's and EarthShell's respective rights and
responsibilities with regard to the resolution of such claim). Notwithstanding
the foregoing, any counterclaim that EKI is permitted to bring against
EarthShell pursuant to the immediately preceding sentence may be asserted by EKI
only to the extent necessary to reduce or limit EKI's liability to EarthShell
with respect to the claims asserted by EarthShell in the relevant action
initiated by EarthShell, and in no event shall EKI assert any such counterclaim
or enforce any judgment obtained in connection therewith in any manner that,
directly or indirectly, results in EarthShell incurring a liability that
EarthShell is required to pay or satisfy. For purposes of this Section 4(b), a
third party claim would not include claims asserted by an officer, director,
manager, employee or member of EKI in their capacity as such. For the avoidance
of doubt, the EarthShell Released Matters shall not include amounts that are or
become due and payable under the Existing Promissory Note, the WN Advance Note
or the EKI Loan Note.


                                       3

         (c) Release of Unknown Claims. Except for the Excluded Matters, the
Parties acknowledge and agree that the releases given pursuant to Sections 4(a)
and (b) extend to all Claims relating to the EKI Released Matters (in the case
of the release given by EarthShell pursuant to Section 4(a)) and the EarthShell
Released Matters (in the case of the release given by EKI pursuant to Section
4(b)), of every nature and kind whatsoever, known or unknown, suspected or
unsuspected, that exist as of the date of this Agreement. Each Party expressly
intends that this Agreement shall be effective as a full and final accord and
satisfaction, and release, of each and every of the EKI Released Matters and the
EarthShell Released Matters. The Parties acknowledge that they are familiar with
Section 1542 of the California Civil Code, which provides as follows:

         A general release does not extend to claims which the creditor does not
         know or suspect to exist in his favor at the time of executing this
         release, which if known by him must have materially affected his
         settlement with debtor.

         The Parties waive and relinquish every right or benefit that they have
or may have under Section 1542 of the California Civil Code or any similar
provision in any jurisdiction, to the full extent that lawfully it may waive
such a right or benefit. The Parties acknowledge that they may later discover
facts in addition to, or different from, those which they now know or believe to
be true, but that it is their intention to fully, finally, and forever settle
and release all of the EKI Released Matters and EarthShell Released Matters,
whether known or unknown, suspected or unsuspected, which now exist, may exist
in the future, or have previously existed, against the persons or entities to
which EarthShell and EKI are hereby granting a release.

Released Parties with regard to any of the EKI Released Matters. Except with
respect to counterclaims, EKI shall not initiate, file, institute, maintain or
proceed upon, or encourage, advise or voluntarily assist any other person or

EarthShell Released Parties,.

         (f) No Admissions. The Parties acknowledge and agree that the releases

heretofore assigned or transferred, or purported to have assigned or
