Section 2(e)), royalty-bearing sublicense to the Technology (the "Sublicense"):

i.to make or have made, at the Plant Facility, the Products; and

ii.to use, sell, offer to sell, import into and otherwise dispose of Products to
Customers solely within the Territory.

        (b)  GP shall not otherwise have the right to sublicense or transfer the
Technology, or any interest in or rights under the Sublicense; provided that the
rights and obligations of GP in, to and under this Agreement may be assigned to
the extent provided by Section 23. Any purported sublicense or transfer by GP

breach for purposes of Section 13(b) hereof.

        (c)  GP shall not, directly or indirectly, market, distribute, sell or
attempt to dispose of any Product to any Person outside the Territory, or to any
Person within the Territory, if GP knows or has reason to believe that such
Person intends to use the Product in question outside the Territory. A breach of
the foregoing shall constitute a material breach for purposes of Section 13(b)
hereof.

        (d)  Subject to Section 10(e) hereof, GP is authorized and required to
use, in connection with the marketing, distribution and sale of Products in the
Territory, the trademarks and service marks (collectively, the "Trademarks")
owned by or licensed to EarthShell that are designated to GP by EarthShell prior
to commercial production of the Products by GP or from time to time thereafter.

        (e)  During the term of this Agreement, GP will use commercially
reasonable efforts to achieve at least twenty-five million dollars (USD
$25,000,000) each year in Net Sales. Notwithstanding the anything herein to the
contrary, if GP is unable to satisfy fully the requirements of any Customer for
Products because of insufficient plant capacity within six (6) months after such
Customer has given GP notice of such requirements in writing (the amount of such
unsatisfied requirements being referred to as "Unfulfilled Customer
Requirements"), GP agrees that the Unfulfilled Customer Requirements for
Products may be satisfied by another EarthShell sublicensee that is designated
by EarthShell without violating the exclusive rights granted by EarthShell
hereunder; provided that GP shall in such event retain its exclusivity with
respect to all Product requirements of such Customer that GP has sufficient
capacity to fulfill on a timely basis.

        (f)    Each supply agreement between GP and a Customer shall be subject
to approval by EarthShell, which approval shall not be unreasonably delayed or
withheld.

        3.    Plant Facility    

        (a)  Within thirty (30) days after the Effective Date, GP will identify
a plant facility in a mutually acceptable location in or near Salt Lake City,
Utah, USA, that will be acquired or leased by GP (the "Plant Facility"). The
Plant Facility shall have, by no later than twelve (12) months after the
Effective Date, a minimum production capacity of five hundred million
(500,000,000) units per year. The size, physical location and specifications of
the Plant Facility will be subject to EarthShell's reasonable approval. The cost
of acquiring the Plant Facility and the cost of any required infrastructure
improvements thereto shall be borne solely by GP. Without limiting the

3

--------------------------------------------------------------------------------

generality of the foregoing, GP shall make a minimum capital investment of ten
million dollars (USD $10,000,000) in the Plant Facility within twelve
(12) months of the Effective Date. GP, at its sole cost and expense, shall make
all repairs and replacements necessary to maintain and operate the Plant
Facility in material compliance with all applicable legal and administrative
code standards of the Territory, and satisfy all applicable customary and
reasonable industry practices with respect thereto in the Territory throughout
the term of this Agreement.

        (b)  GP will permit EarthShell personnel or consultants access to the
Plant Facility as is reasonably necessary in order for them to fulfill
EarthShell's obligations or protect its rights under this Agreement. Prospective
or existing licensee/joint venture partners of EarthShell will be permitted to
have reasonable access to the Plant Facility, upon reasonable advance notice by
EarthShell and during normal business hours, for the purpose of observing the
Plant Facility in operation. Notwithstanding the foregoing, GP will have no
obligation to provide access to the Plant Facility to any prospective or
existing licensee/joint venture partner of EarthShell that has not agreed to
permit access to any plant facility owned or leased by it or a joint venture
entity that is being or in the future will be used to manufacture EarthShell
products.

        (c)  GP will procure and install the number of fully integrated lines of
equipment at the Plant Facility as required to meet its production and revenue
obligations under this Agreement. The cost of acquiring and installing such
lines of equipment, including the direct engineering, design, debugging and
start-up fees and expenses shall be borne solely by GP. GP shall upgrade each
material component of an existing line of equipment on a regular basis and shall
make all repairs and replacements necessary to maintain and operate the lines of
equipment in material compliance with all applicable legal and administrative
code standards of the Territory, and satisfy all applicable customary and
reasonable industry practices with respect thereto in the Territory throughout
the term of this Agreement.

        (d)  Without limiting the foregoing, GP shall pay all other costs and
expenses of whatever nature in connection with the start-up and operation of the
Plant Facility and the manufacture, use, sale, offering for sale and importation
into and commercialization of the Products in the Territory.

        4.    Royalty.    

        (a)  In consideration for the grant of the Sublicense, GP shall pay to
EarthShell a royalty (the "Royalty") of twenty percent (20%) of the Net Sales of
Products by GP each calendar quarter, not to exceed 50% of the Gross Profit
during such calendar quarter.

        (b)  Within fourteen (14) days of the last day of each calendar quarter,
GP shall pay to EarthShell the Royalty payable in respect of all Products
shipped and invoiced by GP during such calendar quarter. Each Royalty payment
shall be accompanied by a written report (the "Royalty Report") prepared by GP
and certified as accurate by the Chief Financial Officer or Treasurer of GP.
Each Royalty Report shall set forth, for the calendar quarter covered by the
Royalty Report, (i) the number of each of the Products shipped by GP, (ii) the
gross invoice price for each of such Products, and (iii) any reductions to the
gross invoice price for purposes of calculating Net Sales.

        (c)  All Royalty payments due under this Agreement shall be paid by GP
in United States dollars.

        (d)  If GP fails to make a timely payment due under this Section 4,
interest at an annual rate equal to twelve percent (12%) shall accrue on the
amount of payment for each day such payment is overdue; provided, however, that
such interest rate shall in no event exceed the maximum rate permitted by
applicable law.

4

--------------------------------------------------------------------------------

        (e)  Any failure to make timely payment of any Royalty shall constitute
a material breach for purposes of Section 13(b) hereof.

        (f)    EarthShell acknowledges that the Royalties payable by GP to
EarthShell under this Agreement may be subject to withholding taxes that may be
assessed under applicable law by any jurisdiction in the Territory and, if GP is
required to so withhold any tax on Royalties, then the amount of Royalties
actually remitted to EarthShell will be net of such withholding. GP will
promptly furnish EarthShell with the official receipt of payment of these taxes
to the appropriate taxing authority. Following the Effective Date and at
EarthShell's option, the Parties agree to cooperate to restructure the Royalty
payments payable hereunder in a manner that will optimize the tax treatment of
such payments, including by possibly converting the Royalty obligation into a
profits participation by EarthShell in GP (it being agreed that any such
restructuring would not be intended to adversely affect the net economic
benefits intended to be conferred on GP hereby).

        5.    Right to Audit.    

        (a)  GP shall keep and maintain complete and accurate records concerning
the sale of the Products at its principal executive offices or at such other
locations as the Parties shall agree. EarthShell or its designated
representative (the "Representative") shall have the right at EarthShell's cost
and expense to review the financial and other records of GP on a quarterly basis
during the term of this Agreement during normal business hours and upon
reasonable prior notice to GP.

        (b)  If GP is ultimately determined to have failed to pay to EarthShell
the full amount of a Royalty payment actually due hereunder, GP shall promptly
pay the full amount of such discrepancy to EarthShell, with interest thereon, at
an annual rate equal to twelve percent (12%); provided, however, that such
interest rate shall in no event exceed the maximum rate permitted by applicable
law. Furthermore, should the results of an audit reveal an underpayment of a
Royalty payment due hereunder in excess of five percent (5%), than all costs and
expenses related to such audit shall be reimbursed to EarthShell by GP within
thirty (30) days of the completion of such credit.

        (c)  If GP is ultimately determined to have overpaid EarthShell a
Royalty payment actually due hereunder, EarthShell shall promptly pay the full
amount of the overpayment to GP, with interest thereon, at an annual rate equal
to twelve percent (12%); provided, however, that such interest rate shall in no
event exceed the maximum rate permitted by applicable law.

        6.    Improvements to Technology.    

        (a)  EarthShell will own all Improvements developed by or for EarthShell
(except as may be provided in any agreement with any sublicensee other than GP)
(the "EarthShell Improvements"). Subject to EarthShell's right to do so, all
EarthShell Improvements shall be included in the Technology licensed hereunder
to GP without additional royalty or other obligation being imposed on GP.

        (b)  EarthShell will own all Improvements developed by or for GP (the
"Company Improvements"). All Company Improvements shall be included in the
Technology licensed hereunder to GP without additional royalty or other
obligation being imposed on GP. GP acknowledges that EarthShell shall have the
right to license GP Improvements to third parties on such terms and conditions
as it shall determine which shall not conflict with this Agreement.

        (c)  Improvements developed jointly by EarthShell and GP ("Joint
Improvements") shall be owned by EarthShell. All Joint Improvements shall be
included in the Technology licensed hereunder to GP without additional royalty
or other obligation being imposed on GP. GP

5

--------------------------------------------------------------------------------

acknowledges that EarthShell shall have the right to license Joint Improvements
to third parties on such terms and conditions as it shall determine which shall
not conflict within this Agreement.

        (d)  Any material Improvements developed by or for any third party
(including an EarthShell sublicensee other than GP) and licensed to EarthShell
shall, if requested by GP and subject to EarthShell's right to do so, be
sublicensed to GP hereunder, subject to the applicable terms and conditions of
such sublicense.

        (e)  Each Party that develops or acquires a material Improvement during
the term hereof will disclose such Improvement in writing to the other Party
promptly after the development or acquisition of such Improvement by such Party.

        7.    Patent Matters.    

        (a)  EarthShell shall have the right, in its sole discretion, to
(i) affirmatively seek patent protection for any Improvement at its sole cost
and expense or (ii) maintain any Improvement as a trade secret; provided that
such Improvement shall be maintained as a trade secret during the pendency of
any patent application.

        (b)  GP shall provide EarthShell, at EarthShell's expense, with such
assistance as may be reasonably requested, from time to time, in connection with
efforts to seek patent protection for any Improvement in accordance with
Section 7(a), including the execution of any documents necessary to obtain and
maintain such patent protection.

        8.    Infringement Matters.    

        (a)  Each of EarthShell and GP will promptly, and in any event within
thirty (30) days of discovery, notify the other in writing of any apparent
infringement of the Technology in the Territory which comes to its attention
while this Agreement remains in effect. EarthShell shall have the sole right, at
its sole cost and expense and in its absolute discretion, to bring any suit to
enjoin such infringement and to recover damages therefor for its sole account.

        (b)  In any action brought by EarthShell pursuant to Section 8(a)
hereof, GP shall (i) cooperate fully with EarthShell and provide whatever
assistance is reasonably requested by EarthShell in connection with such suit,
including the preparation and signing of documents at EarthShell's expense.

        (c)  GP shall promptly notify EarthShell in writing of (i) any claim or
threatened claim by any Person that the use of the Technology by GP in
connection with the manufacture, use or sale of any Product by GP or any
Customer infringes or violates the patent, trade secret or other intellectual
property rights of such Person in any of the Territory and (ii) the commencement
of any lawsuit against GP, or any of its respective customers, asserting any
such claim (an "EarthShell Infringement Action"). EarthShell shall assume and
control the defense of any EarthShell Infringement Action, at its sole cost and
expense, irrespective of whether EarthShell is named as a defendant therein. GP
will assist EarthShell in the defense of any EarthShell Infringement Action by
providing such information, fact witnesses and other cooperation as EarthShell
may request from time to time; provided that EarthShell shall reimburse GP for
any out-of-pocket expenses incurred by GP in connection therewith. GP shall have
the right to be represented in connection with an EarthShell Infringement Action
by its own legal counsel, at its own expense, provided that such legal counsel
will act only in an advisory capacity. If EarthShell does not assume the defense
of any EarthShell Infringement Action, GP shall have the right, but not the
obligation, to assume the defense of such lawsuit, utilizing legal counsel of
its choice. EarthShell shall bear the reasonable costs and expenses of such
legal counsel. If GP so assumes the defense of an EarthShell Infringement
Action, GP shall have no right to settle such EarthShell Infringement

6

--------------------------------------------------------------------------------

Action unless GP shall have received the prior written consent of EarthShell
which shall not be unreasonably withheld or delayed.

        (d)  If the court, in any EarthShell Infringement Action, enters a final
and non-appealable order finding that the Technology infringes or violates, in
whole or in part, the intellectual property rights of another Person in any of
the Territory and requiring GP (i) to obtain a license under any third party's
patent not licensed hereunder in order to continue make and sell in the
Territory Products incorporating Technology as contemplated by this Agreement,
and to pay a royalty or fee under such license, and the infringement of such
patent cannot reasonably be avoided by GP, or (ii) to pay any damages on account
of such infringement or violation, EarthShell shall pay the amount of any such
fee or royalty payable and any such damages to the extent that the infringement
or violation found by such court resulted from GP's use of Technology in the
Territory within the scope of the Sublicense granted hereunder; provided that,
in no event shall EarthShell's liability under this Section 8(d) exceed the
specified amount in Section 12(b) hereof.

        9.    Duties and Obligations of EarthShell.    

        In addition to, and not in limitation of, the other duties and
obligations of EarthShell, as set forth in this Agreement, EarthShell shall have

--------------------------------------------------------------------------------

advertisement, marketing, distribution and sale of the Products. The right to
use such Trademarks is included within the Sublicense herein granted. Except as
otherwise agreed by EarthShell, GP shall use its reasonable efforts to cause
each Product manufactured by GP to bear at least one of the Trademarks
designated by EarthShell. The specific placement, size, and detail of any
Trademark on each Product must be approved by EarthShell (which approval shall
not be unreasonably withheld or delayed) GP shall not in any manner represent
that it has any ownership interest any Trademarks licensed hereunder. GP
acknowledges that use of the Trademarks shall not create in its own favor any
right, title, or interest in or to the Trademarks, and that all uses thereof by
GP shall inure to the benefit of EarthShell. GP shall cooperate with EarthShell
in the execution of any appropriate and necessary documents in connection with
the registration of any Trademarks.

        (b)  Upon termination of this Agreement, GP shall cease and desist from
use of the Trademarks in any way, including any word or phrase that is similar
to or likely to be confused with any of the Trademarks. However, in the event of
termination of this Agreement, GP shall have the right to sell existing stock
and inventory of manufactured Products for a period of sixty (60) days and
thereafter shall deliver to EarthShell or its duly authorized representative all
materials upon which the Trademarks appear.

        (c)  GP acknowledges that the Technology in existence on the date hereof
is novel and unique in the foodservice disposable products industry. GP shall
not challenge or question the validity or ownership of the Trademarks or,
subject to the provisions of applicable law, any Licensed Patents. GP shall
continue to make all required payments under this Agreement to EarthShell during
any challenge of the validity of any of the Licensed Patents (or claims thereof)
included in the Technology. In the event GP fails to continue to make such
payments based upon or in connection with such a challenge, EarthShell may at
its option terminate this Agreement upon written notice to GP.

        (d)  GP represents, warrants and covenants to EarthShell that (i) the
Products manufactured by GP shall conform with all of the specifications
provided by EarthShell pursuant to Section 9(a) and that (ii) GP shall maintain
quality standards for the Products in conformity with EarthShell's standard
quality control manual or procedures, which EarthShell agrees shall be
commercially reasonable.

        (e)  GP shall obtain or provide, and maintain at all times, product
liability insurance as is reasonable and customary for the industry with such
insurer as shall be reasonably satisfactory to EarthShell; provided, however,
any insurer rated by AM Best (or a comparable agency) at a rating of A-10 or
better (or a comparable rating) shall at all times be deemed a reasonably
satisfactory insurer. Each such insurance policy will require that the insurer
give EarthShell at least thirty (30) days prior written notice of any alteration
in or cancellation of the terms of such policy. GP shall furnish to EarthShell a
certificate or other evidence reasonably satisfactory to EarthShell that such
insurance coverage is in effect and that EarthShell is an additional insured
with respect to such policy.

        (f)    GP shall mark all of the Products and related documents with all
applicable patent numbers, in accordance with EarthShell's instructions and as
required by the patent laws in effect in the Territory or as reasonably
instructed by EarthShell.

        (g)  GP or its agents shall be solely responsible for the payment and
discharge of any taxes, duties, or withholdings relating to any transaction of
GP or its agents in connection with the manufacture, use, sale or
commercialization of the Technology or the Products in the Territory, excluding
any tax or duty based on the income of EarthShell.

        (h)  GP grants EarthShell the right of first priority to supply all of
GP's raw materials for Products (the "Raw Materials"). GP shall regularly and
routinely inform EarthShell of all of its

8

--------------------------------------------------------------------------------

requirements for Raw Materials prior to purchasing any Raw Materials from any
other Person. GP may request EarthShell to submit a bid or proposal offer for
the supply of particular Raw Materials. If EarthShell desires to supply
particular Raw Materials to GP, EarthShell may submit a bid or proposal for the
supply of such Raw Materials ("Offered Raw Materials") and, if such a bid or
proposal is made by EarthShell, EarthShell and GP shall negotiate in good faith
to enter into a supply agreement or purchase order with regard to such Offered
Raw Materials unless GP has received a written offer from a third-party for such
Offered Raw Materials at a price and on terms and conditions materially more
favorable to GP than those offered or proposed by EarthShell. EarthShell may, no
more frequently than once every 12 months, be permitted to engage an independent
accounting firm reasonably acceptable to GP to conduct an audit solely of GP's
obligations under this Section 10(h). Prior to any such audit, EarthShell shall
provide GP with advance notice, and such audit shall be conducted at the
appropriate GP premises during normal business hours. Such accounting firm shall
be required to execute a written confidentiality agreement with GP prior to
commencing such audit and shall not disclose to EarthShell any confidential
information of GP acquired during such audit. To the extent that such an audit
indicates that GP failed to effectively give EarthShell the right of first offer
with respect to the provision of particular Raw Materials that is contemplated
by this Section 10(h) GP shall pay to EarthShell (i) the actual cost of the
audit and (ii) twice the difference between the price GP paid for such Products
and the price offered for such Raw Materials by EarthShell. The remedy provided
in the prior sentence shall not be exclusive of or limit any other remedies that
may be available to EarthShell.

        (i)    GP represents and warrants to EarthShell that GP presently has
the financial resources required to perform all of its obligations under this
Agreement. During the thirty (30) day period following the Effective Date, GP
shall provide to EarthShell such GP financial statements and other information
as EarthShell may request and is reasonably required to demonstrate to the
satisfaction of EarthShell that GP presently has such resources. Notwithstanding
anything contained in this Agreement to the contrary, this Agreement shall
terminate if, prior to the expiration of the thirty (30) day period following
the Effective Date, GP has not demonstrated to the satisfaction of EarthShell
that GP presently has such resources.

        11.    Representations and Warranties of EarthShell.    

        (a)  EarthShell hereby represents and warrants to GP that EarthShell has
a valid and enforceable license to use the Technology within the scope of the
rights granted under the Sublicense and has the right to sublicense the
Technology to GP within the scope of the rights granted under the Sublicense as
set forth in this Agreement.

        (b)  EXCEPT AS EXPRESSLY SET FORTH IN SECTION 11(a) OF THIS AGREEMENT,
EARTHSHELL DOES NOT MAKE OR GIVE, AND HEREBY EXPRESSLY DISCLAIMS, ANY AND ALL
WARRANTIES, WHETHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, INCLUDING THE IMPLIED
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, IN REGARD TO
(i) ANY PRODUCTS WHICH MAY BE MANUFACTURED, USED OR SOLD BY GP AND WHICH ARE
BASED UPON OR UTILIZE ANY OF THE TECHNOLOGY; AND (ii) IN REGARD TO ANY SERVICES
PROVIDED TO GP BY EARTHSHELL HEREUNDER.

from couriers, suppliers, or other third parties that have limited access only
to loading docks, mail rooms, office reception areas and other areas in which
Products are not being manufactured and in which no Confidential Information is

        17.    Savings Clause.

invalid by reason of any law or by decree of a court or competent jurisdiction,
the invalidation of such part or provision of this Agreement shall not
invalidate the remaining parts or provisions hereof, and the remaining parts and
provisions of this Agreement shall remain in full force and effect.

        18.    Waiver.

right, power or privilege hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or privilege preclude any other
or further exercise thereof or of any other right or privilege.

laws of Delaware, without giving effect to the choice of law rules thereof.

        This Agreement may be amended only by the consent of each of the Parties
expressed in writing, signed by their duly authorized representatives.

        21.    Dispute Resolution.    

        (a)  All claims, disputes, controversies and other matters in question
arising out of or relating to this Agreement, or to the alleged breach hereof,
which cannot be resolved by the Representatives shall be settled by negotiation
between the executives of GP and EarthShell. If such executive negotiation is
unsuccessful within ten business days, GP and EarthShell shall submit the
dispute to non-binding mediation with an independent party mutually acceptable
to GP and EarthShell (with the cost of the mediation to be borne equally by GP
and EarthShell). If GP and EarthShell cannot mutually agree to a resolution
within ten business days, either Party may refer the dispute to binding
arbitration in accordance with procedures set forth in this Section 21. Each of
GP and EarthShell (i) waives the right to bring an action in any court of
competent jurisdiction with respect to any such claims, controversies and
disputes (other than any such action to enforce

12

--------------------------------------------------------------------------------

the award or other remedy resulting from any arbitration pursuant to this
Section 21), and (ii) waives the right to trial by jury in any suit, action or
other proceeding brought on, with respect to or in connection with this
Agreement.

        (b)  Upon filing of a notice of demand for binding arbitration by either
GP or EarthShell, arbitration with the American Arbitration Association, or
comparable association if the American Arbitration Association is no longer in
existence, shall be commenced and conducted as follows:

        i.      All claims, disputes, controversies and other matters in
question shall be referred to and decided and settled by a standing panel of
three arbitrators, one selected by each of GP and EarthShell and the third by
the two arbitrators so selected. Selection of arbitrators shall be made within
thirty days after the date of the first notice of demand given pursuant to this
Section 21 and within thirty days after any resignation, disability or other
removal of such arbitrator. Following appointment, each arbitrator shall remain
a member of the standing panel, subject to refusal for just cause or resignation
or disability.

        ii.    The cost of each arbitration proceeding, including without
limitation the arbitrators' compensation and expenses, meeting room charges,
court reporter transcript charges and similar expenses shall be borne by the
party whom the arbitrators determine has not prevailed in such proceeding, or
borne equally by GP and EarthShell if the arbitrators determine that neither
party has prevailed. The arbitrators shall also award the party that prevails
substantially in its pre-hearing position its reasonable attorneys' fees and
costs incurred in connection with the arbitration. The arbitrators are
specifically instructed to award attorneys' fees for instances of abuse of the
discovery process.

        iii.    The sites of the arbitration shall be in Santa Barbara,
California unless GP and EarthShell agree otherwise.

        (c)  The arbitrators shall have the power and authority to, and to the
fullest extent practicable shall, abbreviate arbitration discovery in a manner
that is fair to GP and EarthShell in order to expedite the conclusion of each
alternative dispute resolution proceeding.

        (d)  The arbitration shall be governed by, and all rights and
obligations specifically enforceable under and pursuant to, the Federal
Arbitration Act (9 U.S.C. § 1, et. seq.).

        (e)  The arbitrators are empowered to render an award of general
compensatory damages and equitable relief (including, without limitation,
injunctive relief), but are not empowered to award punitive damages. The award
rendered by the arbitrators (i) shall be final, (ii) shall not constitute a
basis for collateral estoppel as to any issue, and (iii) shall not be subject to
vacation or modification. The arbitrators shall render any award or otherwise
conclude the arbitration no later than one hundred and eighty (180) days after
the date notice is given pursuant to this Section 21.

        22.    Counterparts.    

        This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

        23.    Assignment.    

        The rights and obligations in, to and under this Agreement shall be
binding upon and inure to the benefit of the Parties, their legal
representatives, successors and assigns. Neither Party may assign this Agreement
or any rights hereunder without the prior written consent of the other Party.

13

--------------------------------------------------------------------------------

        24.    Entire Agreement.    

        This Agreement supersedes any prior understandings or agreements,
whether written or oral, and any contemporaneous oral agreements, between the
Parties hereto in regard to the subject matter hereof contains the entire
agreement between the Parties in regard to the subject matter hereof.

        IN WITNESS WHEREOF, the Parties have caused this Technology Sublicense
Agreement to be executed and delivered by their duly authorized representatives
