                                   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
<PAGE>

         (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.

                                       4

EarthShell shall not initiate, file, institute, maintain or proceed upon, or
encourage, advise or voluntarily assist any other person or entity to initiate,
institute, maintain or proceed upon, any claim against EKI or the other EKI
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
entity to initiate, institute, maintain or proceed upon, any claim against

EarthShell Released Parties,.

         (f) No Admissions. The Parties acknowledge and agree that the releases
are entered into as a compromise of doubtful and disputed claims, and is not to
be construed as an admission of liability on the part of any Party, by each of
whom all liability is expressly denied.

         (g) No Assignments. EarthShell represents and warrants that it has not
heretofore assigned or transferred, or purported to have assigned or
transferred, to any corporation, partnership, limited liability company, other

Section 4(a) and agrees to indemnify and hold harmless EKI and the other EKI

(evidencing a Company debt or otherwise) or other understanding to which the
Company is a party or by which any property or asset of the Company is bound or
affected, or (iii) result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental

accordance with this Agreement and paid for in full by Purchasers, will be duly

charge, claim, security interest, encumbrance, right of first refusal or other
restriction. At such time as the Securities may be converted into the
appropriate number of shares of common stock of the Company (the "Common
Shares"), such Common Shares will be duly and validly issued, fully paid and
non-assessable, free and clear of any lien, charge, claim, security interest,
encumbrance, right of first refusal or other restriction.

          (f) As of the date hereof, all of the outstanding shares of common
stock of the Company are duly authorized, validly issued, fully paid and
non-assessable and have been issued in compliance with all applicable securities
laws.

          (g) There is no action, suit, inquiry, notice of violation, proceeding
or investigation pending or, to the knowledge of the Company, threatened against

arbitrator, governmental or administrative agency or regulatory authority
(federal, state, county, local or foreign) which adversely affects or challenges
the legality, validity or enforceability of this Agreement or the Securities.

          (h) The Company has filed all reports required to be filed by it under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including
pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date
hereof (the foregoing filings being collectively referred to herein as the "SEC
Reports"). As of their respective dates, the SEC Reports complied in all
material respects with the requirements of the Securities Act of 1933, as
amended (the Securities Act") and the Exchange Act and the rules and regulations
of the Securities and Exchange Commission (the "Commission") promulgated
thereunder, and none of the SEC Reports, when filed, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Reports comply in all material
respects with applicable accounting requirements and the rules and regulations
of the Commission with respect thereto as in effect at the time of filing. Such
financial statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved,
except as may be otherwise specified in such financial statements or the notes
thereto, and fairly present in all material respects the financial position of
the Company as of and for the dates thereof and the results of operations and
cash flows for the periods then ended.

          (i) As of the date hereof, and after giving effect to the filing og
the Certificate of Designation and the transactions contemplated by this
Agreement, the authorized capital stock of the Company consists of (i)
40,000,000 shares of common stock, $0.01 par value per share, of which
19,340,188 are issued and outstanding, and (ii) 10,000,000 shares of Preferred
Stock, of which 100 shares are designated Series B Convertible Preferred Stock,
of which 8,000,000 have been designated Series C Convertible Preferred Stock.,
and of which 400,000 have been designated as Series D Convertible Preferred
Stock. There is no other class of preferred stock authorized or outstanding. All
common stock and series of Preferred Stock referred to in this Section 2.1(i)
are referred to collectively herein as "Corporation Shares." All of the issued
and outstanding Corporation Shares have been validly issued, are fully paid and
are non-assessable. All Corporation Shares have been issued in compliance with
all applicable federal and state securities laws.

          (j) Since December 31, 2005, there has not been any material adverse
change in the business, operations, financial condition or prospects of the
Company, except as has been publicly disclosed in SEC Reports or press releases
and it being understood that the Company needs additional financing to continue
as a "going concern."

      2.2 Representations and Warranties of Purchasers.

      Each Purchaser individually as to itself, and not jointly and severally,
represents and warrants to the Company as follows:

                                       5
<PAGE>

          (a) Such Purchaser, if not a natural person, is duly organized,
validly existing and in good standing, under the laws of its state of formation.
Such Purchaser, if not a natural person, has full power and authority to enter
into and perform this Agreement. The execution and delivery by such Purchaser of
this Agreement and the performance by such Purchaser of its obligations
hereunder, in each case if such Purchaser is not a natural person, have been
duly authorized and approved by all requisite company action.

          (b) This Agreement has been duly executed and delivered by such
Purchaser or duly authorized representatives of such Purchaser and constitutes
the valid and binding obligation of such Purchaser enforceable against such
Purchaser in accordance with its terms.

          (c) No consent, authorization, order or approval of, or filing or
registration with, any governmental commission, board or other regulatory body
of the United States or any state or political subdivision thereof is required
for or in connection with the consummation by such Purchaser of the transaction
contemplated hereby.

          (d) Neither the execution and delivery of this Agreement by such
Purchaser, nor the consummation by such Purchaser of the transaction
contemplated hereby, will conflict with or result in a breach of any of the
terms, conditions or provisions of its charter documents or operating agreement,
or of any statute or administrative regulation, or of any order, writ,
injunction, judgment or decree of any court or governmental authority or of any
arbitration award.

          (e) Such Purchaser is not a party to any written or oral contract,
agreement, indenture, debenture, note, commitment or other instrument under the
terms of which performance by such Purchaser according to the terms of this
Agreement will be a default or an event of acceleration, or grounds for
termination, or whereby timely performance by such Purchaser according to the
terms of this Agreement may be prohibited, prevented or delayed.

          (f) Such Purchaser has not dealt with any person or entity which is or
may be entitled to a broker's commission, finder's fee, investment banker's fee
or similar payment for arranging the transaction contemplated hereby or
introducing the parties to each other.

          (g) Such Purchaser is acquiring the Securities (and upon exercise of
the Securities, the Common Shares) for such Purchaser's own accounts and not
with a present view to or for sale in connection with any distribution of all or
any part of the Securities or the Common Shares. Such Purchaser understands that
such parties can not, directly or indirectly, transfer, offer, sell, pledge,
hypothecate or otherwise dispose of all or any part of the Securities or the
Common Shares or its or his interest in the Securities or the Common Shares (or
solicit any offers to buy, purchase or otherwise acquire to take a pledge of all
or any part thereof) except (i) as provided in Section 3 hereof or (ii) in a
manner that does not violate the registration or any other applicable provisions
of the Securities Act (or any other applicable federal securities laws) or any
applicable state securities laws; provided that in the case of a transfer under
clause (ii) hereof, the transferee of the Securities or the Common Shares from
such Purchaser must acknowledge and agree to abide by the provisions of this
Section 2.2(g) and must present to the Company or its counsel (A) a written
opinion in form and substance of legal counsel experienced in securities law
matters satisfactory to the Company indicating that the proposed transfer will
not be in violation of any of the registration provisions of the Securities Act
and the qualification provisions of applicable state securities laws or similar
successor laws, and the rules and regulations promulgated thereunder, or (B)
evidence satisfactory to the Company of full compliance with the provisions of
Rule 144 under the Securities Act or other available exemptions under the
Securities Act.

                                       6
<PAGE>

          (h) Such Purchaser has been furnished with, and hereby acknowledges
receipt of, such information as it deems necessary to evaluate its or his
investment in the Securities and understands the risks of, and other
considerations relating to, ownership of the Securities. Such Purchaser has
extensive knowledge and experience in financial affairs so that such Purchaser
is capable of evaluating the merits and risks of an investment in the Securities
and has the capacity to protect its or his own interests in connection with
purchase of the Securities. Such Purchaser's financial situation is such that it
can afford to bear the economic risk of holding the Securities for an indefinite
period of time and can afford to suffer the complete loss of its investment in
the Securities.

      3. Registration Covenant of the Company

      The Company covenants and agrees with each Purchaser as follows:

          (a) If at any time either Purchaser requests that the Company file a
registration statement for a secondary public offering of all or any portion of
the Common Shares, the Company will file, within sixty (60) business days of
receipt of such Purchaser's request, a registration statement with the
Commission which complies in all material respects with the requirements of the
Securities Act seeking the public sale of the number of Common Shares specified
in such notice. The Company will pay all reasonable expenses incurred in
connection with any registration, qualification and compliance requested
hereunder (excluding underwriting discounts and commissions), including, without
limitation, all filing, registration and qualification, printing and accounting
fees and the fees and disbursements of counsel for the Company. The Company
shall notify each Purchaser in writing at least fifteen (15) days prior to the
filing of any registration statement under the Securities Act for purposes of a
public offering of securities and will afford each Purchaser an opportunity to
include in such registration statement all or part of any Common Shares held by
such Purchaser. Each Purchaser desiring to include in any such registration
statement all or any part of his or its Common Shares, shall, within fifteen
(15) days after the above-described notice from the Company, so notify the
Company in writing. If a Purchaser decides not to include all of its Common
Shares in any registration statement thereafter filed by the Company, such
Purchaser shall nevertheless continue to have the right to include any Common
Shares in any subsequent registration statement as may be filed by the Company
with respect to offerings of its securities, all upon the terms and conditions
set forth herein.

                                       7
<PAGE>

          (b) The Company will use its diligent best efforts (i) to cause such
registration statement to become effective and (ii) to cause such registration
statement to remain effective until the completion of the proposed offering and
(iii) to prepare and file with the Commission such amendments and supplements to
the registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the sale or other disposition of all the Common
Shares covered by such registration statement, including, without limitation,
such amendments and supplements as may be necessary to reflect the intended
method of disposition from time to time of the holder.

          (c) The Company will furnish to each holder of Common Shares covered
by such registration statement such numbers of copies of such registration
statement, any amendments thereto, any documents incorporated by reference
therein, the prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the sale or other disposition of the
Common Shares.

          (d) The Company will use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
blue sky laws of such jurisdictions as shall be reasonably requested by each
holder of Common Shares covered by such registration statement and do any and
all other acts and things that may be necessary under such securities and blue
sky laws to enable each holder to consummate the sale or other disposition of
the Common Shares owned by it; provided that the Company shall not be required
in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such state or
jurisdiction and except as may be required by the Securities Act.

          (e) Within a reasonable time before each filing of the registration
statement or prospectus or amendments or supplements thereto with the SEC, the
Company will furnish counsel selected by any holder of the Common Shares copies
of such documents proposed to be filed, which counsel shall have a reasonable
opportunity to review and comment thereon.

          (f) The Company will promptly notify each holder of Common Shares
covered by the registration statement of the happening of any event which makes
any statement made in the registration statement or related prospectus untrue or
which requires the making of any changes in such registration statement or
prospectus so that they will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein in the light of the circumstances under which they
were made not misleading; and, as promptly as practicable thereafter, prepare
and file with the Commission and furnish a supplement or amendment to such
prospectus so that, as thereafter deliverable to the purchasers of such Common
Shares, such prospectus will not contain any untrue statement of a material fact
or omit to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

          (g) The Company will use its best efforts to prevent the issuance of
any order suspending the effectiveness of the registration statement and, if one
is issued, shall use its best efforts to obtain the withdrawal of any order
suspending the effectiveness of the registration statement at the earliest
possible moment.

                                       8
<PAGE>

          (h) If the registration statement under which the Company gives notice
under this Section 3 is for an underwritten offering, the Company shall so
advise the Purchasers. In such event, the right of any such Purchaser to be
included in any such registration statement pursuant to this Section 3 shall be
conditioned upon such Purchaser's participation in such underwriting and the
inclusion of such Common Shares in the underwriting to the extent provided
herein. The Company, and the Purchasers who intend to participate in such
underwritten offering, shall enter into an underwriting agreement in customary
form with an underwriter or underwriters selected for such underwriting by the
Company.

          (i) To the fullest extent permitted by law, the Company will indemnify
and hold harmless each holder selling Common Shares under the registration
statement, each other entity or person who participates in the offering of the
Common Shares under such registration statement, and each other entity or
person, if any, who controls (within the meaning of the Securities Act) such
seller or participating entity or person (individually and collectively, the
"Indemnified Person"), against any losses, claims, damages or liabilities (joint
or several) to which they may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (joint or several), or actions in respect thereof, arise
out of or are based upon: (i) any untrue statement or alleged untrue statement
of a material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state securities law, and the Company shall pay to each such Indemnified Person,
as incurred, any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the Company shall not be liable to
any Indemnified Person in any such case for any such loss, claim, damage,
liability, or action to the extent that it arises out of or is based upon (i)
any untrue statement or alleged untrue statement or omission or alleged omission
in such registration statement, preliminary or final prospectus, or amendment or
supplement thereto in reliance upon and in conformity with written information
furnished to the Company by such person expressly for use therein or (ii) such
person's failure to deliver a prospectus as required by the Securities Act.
