<PAGE>


      (b)  Sweetheart  shall  not  otherwise  have the  right to  sublicense  or

provided,  however,  that the rights and  obligations  of Sweetheart  in, to and

sell or attempt to  dispose of any  Product to any Person  outside of the Market
Segments  or  outside  of the  Territory,  or to any  Person  within  the Market
Segments or within the Territory,  if Sweetheart  knows or has reason to believe
that such Person  intends to use such  Product  outside  the Market  Segments or
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(a),  Sweetheart 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  Sweetheart  by
EarthShell prior to commercial  production of the Products by Sweetheart or from
time to time thereafter;  provided, however, that Sweetheart shall have received
not less than ninety (90) days'  advance  notice of the  effective  date of such
designation and provided,  further, however, that any such designation shall not
apply to work in progress,  finished goods or other  inventories  existing as of
the effective date of such designation.

      (e)  Notwithstanding  anything to the  contrary in Section  2(a),  whether
expressed or implied,  and subject to the provisions of Section 25, in the event
Sweetheart timely meets all applicable Net Sales milestones set forth in Exhibit
C hereto with respect to the sale or  distribution of Products within the Market
Segments and within the  Territory  (such  milestones  shall be  determined on a
cumulative  basis such that prior Net Sales  will be  aggregated  with prior and
current milestones  benchmarks to determine whether the applicable milestone has
been achieved),  and in the further event that  Sweetheart  timely complies with
its Equipment purchase obligation set forth in Sections 3(a) and 13(d) (such Net
Sales milestones and Equipment purchase obligations are collectively referred to
as the  "MILESTONES"),  then  until  the  earliest  to  occur  of (i)  the  date
Sweetheart  fails  to meet  one or more of the  Milestones,  as the  same may be
satisfied  by the  payment of  equivalent  EC Profit  Distributions  pursuant to
Section 4(f), (ii) the date this Agreement is terminated pursuant to Section 13,
(iii) the date  Sweetheart  achieves  $500 million in Net Sales for a continuous
twelve (12) month period,  (iv)  December 31, 2007,  or (v) the date  Sweetheart
notifies  EarthShell  pursuant  to  Section  3(b)  that  it  has  triggered  the
EarthShell  Purchase  Obligation  and  Sweetheart  has  been  released  from any
obligation  related thereto  pursuant to the terms of the contract with DTE (the
period commencing on the Effective Date and ending on the earliest of such dates
is  referred  to  herein  as  the  "EXCLUSIVITY  PERIOD"),  and  subject  to the
conditions  imposed by this Section 2(e) and Sections 2(f) and (h) and 3(a), and
subject  further  to  the  non-exclusive  rights,  if  any,  of  the  EarthShell
sublicensees  listed on Exhibit E, Sweetheart  shall have the exclusive right to
make, use, sell, offer to sell, import into, distribute and otherwise dispose of
and  commercialize  the Products to Persons within the Market Segment and within
the  Territory  (such  Persons are referred to herein as  "CUSTOMERS").  For the
avoidance of doubt, in accordance with Section 4(f),  Sweetheart may satisfy any
Milestone  relating  to  Net  Sales  by  payment  to  EarthShell  of  EC  Profit
Distributions,  and, if necessary,  supplemental payments, as shall equal the EC
Profit  Distributions  that would have been paid to EarthShell had the Net Sales
Milestone been achieved, and Sweetheart shall be deemed to have satisfied or met
the Net Sales Milestone in question by making such payments.

      (f)  Subject  to  Sections  2(e) and (h) and 3(a) and this  Section  2(f),
EarthShell   covenants  that,  during  the  Exclusivity  Period,  it  shall  not
sublicense,  license  or  otherwise  grant to or permit  any  Person  other than
Sweetheart  the  right to,  nor  shall it  utilize  the  Technology  or any part
thereof,  to make, have made, use, sell, offer to sell, import into or otherwise
commercialize  any Product  within the Market  Segments and within the Territory
(subject to the non-exclusive rights, if any, of EarthShell's sublicensees under
those  certain  sublicense  agreements  listed on Exhibit E),  provided  that if
Sweetheart  is unable to satisfy  fully the  requirements  of any  Customer  for
Products  because of  insufficient  plant capacity  within nine (9) months after
such Customer has given Sweetheart  notice of such  requirements in writing (the
amount  of such  unsatisfied  requirements  being  referred  to as  "UNFULFILLED
CUSTOMER  REQUIREMENTS"),   Sweetheart  agrees  that  the  Unfulfilled  Customer
Requirements  for Products,  or any portion  thereof,  may be satisfied by other
EarthShell sublicensees designated by Sweetheart without violating the exclusive
rights granted by EarthShell hereunder; provided, however, that Sweetheart shall
in such event  retain  its  Customer  exclusivity  with  respect to all  Product
requirements of such Customer that Sweetheart has sufficient capacity to fulfill
on a timely basis.

      (g)  Following  the  end  of  the  Exclusivity   Period,  the  exclusivity
restrictions  set  forth in  Sections  2(e) and (f) shall  cease to  apply,  and
EarthShell may itself,  or sublicense,  license or otherwise grant to any Person
the non-exclusive right to, or to utilize the Technology or any part thereof, to
make,  have  made,  use,  sell,   offer  to  sell,   import  into  or  otherwise
commercialize  any Product to any Person  within the Market  Segments and within
the Territory.  Notwithstanding  anything contained herein to the contrary,  if,
following  the  end of  the  Exclusivity  Period,  the  Net  Sales  realized  by
Sweetheart  for any  calendar  year  thereafter  for any  category of the Market
Segments  set  forth  on  Exhibit  B are  less  than  the  product  obtained  by
multiplying  (i) the lesser of (A) the total Net Sales  achieved  by  Sweetheart
during the twelve (12) month period ending with the calendar quarter immediately
preceding the end of the Exclusivity  Period,  and (B) $50 million,  by (ii) the
Minimum Market Segment Threshold  Percentage for such category of Market Segment
for the applicable  calendar year, as determined on a cumulative  basis for each
calendar year following the end of the Exclusivity Period, then EarthShell shall
have the right, upon thirty (30) days' prior notice to Sweetheart,  to terminate
Sweetheart's  rights under this  Agreement  with respect to such category of the
Market  Segment;  provided,  however,  that  Sweetheart  may continue to sell or
distribute  unlimited quantities of Products to Customers within such terminated
category of the Market Segment for whom it was actively selling and distributing
Products at the time it receives the termination  notice  (although it shall not
have any further  rights to sell or  distribute  Products to any other  Customer
within such terminated category of the Market Segment).

      (h) Notwithstanding  any provision of this Agreement to the contrary,  the
Sublicense  granted  Sweetheart   pursuant  to  Section  2(a)  and  Sweetheart's
exclusive  rights  pursuant to Section 2(e) shall terminate with respect to cups
for hot  beverages,  and such  "hot  cups"  will no longer  be  included  in the
definition of Products,  if Sweetheart fails to fund such amount and within such
a time frame as will reasonably enable Sweetheart to commercially operate, on or
before  December 31, 2003, a  commercially  effective  manufacturing  process or
production  capability  for such "hot  cups," and to have at least $2 million in
Net Sales by the end of the first calendar quarter of 2004.

3.    PLANT FACILITIES; EQUIPMENT PURCHASES

      (a) Subject to Section 3(b), from and after the Effective Date, Sweetheart
shall  be  responsible  for its  requirements  for  the  manufacture,  sale  and
distribution  of Products within the Market Segments and within the Territory at
such  facilities  within the  Territory as  Sweetheart  shall select in order to
manufacture  and distribute the Products  (separately,  a "PLANT  FACILITY" and,
collectively, the "PLANT FACILITIES"); provided, however, that it is anticipated
that the  initial  Plate  Line will be  installed  at  Sweetheart's  St.  Thomas
facility  in  Owings  Mills,  Maryland.  Subject  to  Sections  3(b) and  13(d),
Sweetheart shall order and purchase from Certified Equipment Vendors,  and shall
install and debug, such quantity of Modules and Lines as shall reasonably enable
it to meet the next  succeeding  Net Sales  Milestones  set  forth on  Exhibit C
(collectively,  the  "EQUIPMENT") on such terms and conditions as are acceptable
to  Sweetheart  in its  sole  discretion  (it is  understood  that  Sweetheart's
purchase  and  installation  of the Initial  Modules  will enable it to have the
capacity to meet the initial  Net Sales  Milestones  as set forth on Exhibit C).
Except as set forth in Section 13(d),  Sweetheart's  failure to achieve any such
Milestones will not allow EarthShell to terminate this Agreement,  but will, and
as its sole remedy, permit it to end the Exclusivity Period upon notice given by
EarthShell to  Sweetheart  (which notice shall be delivered not more than ninety
(90) days following  Sweetheart's  notification to EarthShell that it has failed
to meet the Milestone in question,  it being agreed that EarthShell's failure to
timely give such notice will automatically  result in the Milestone being deemed
to have been achieved). The purchase order for the Initial Modules in the manner
contemplated  in Section  13(d) shall take place on or before  October 31, 2002,
and the  installation  and  debugging  of the Plate Line and,  if  purchased  by
Sweetheart, the Supplemental Modules, shall take place at a Plant Facility on or
before May 15,  2003  (unless  such date is delayed by the  Certified  Equipment
Vendor through no fault of Sweetheart,  in which event either Party may elect to
terminate this Agreement under Section 13(d) if the Plate Line and, if purchased
by Sweetheart,  the Supplemental Modules meeting the Required Specifications are
not  installed  and  debugged  at a Plant  Facility by May 15,  2003;  provided,
however,  that a Force Majeure Event shall be deemed to occur if the Plate Line,
and if purchased by Sweetheart,  the Supplemental Modules,  meeting the Required
Specifications  are not installed and debugged at a Plant  Facility on or before
May 15, 2003 through no fault of Sweetheart. Except as provided in Section 3(b),
the cost of procuring  and  installing  the  Equipment  shall be borne solely by
Sweetheart.


                                       9

      (b) In the event that Sweetheart  notifies EarthShell that it is unable or
unwilling  to secure  financing  for its  purchase of the  Supplemental  Modules
(which  notification  must be made prior to the installation of the Supplemental
Modules at a Plant Facility),  and assuming that the Preliminary Validation Date
has occurred (or if it has not occurred,  neither Party has elected to terminate
this  Agreement  pursuant to Section  13(e)),  then,  at  Sweetheart's  request,
EarthShell shall thereupon be deemed to have assumed Sweetheart's  obligation to
purchase  the  Supplemental  Modules  and shall  indemnify  and hold  Sweetheart
harmless for any amounts  payable,  and,  within (30) days following  receipt of
such notice, shall reimburse Sweetheart for any amounts paid, as applicable,  to
DTE (whether as a deposit or otherwise) in connection  with the purchase of such
Supplemental  Modules.  In connection  with such  assumption and  reimbursement,
Sweetheart shall assign to EarthShell or its assignees, without recourse, all of
its right, title and interest in and to the Supplemental  Modules (including any
rights under the purchase agreement with DTE for the Supplemental Modules), free
of all  liens,  encumbrances  and  adverse  claims  of any kind,  and  including
Sweetheart's right to enforce warranty  obligations and damage remedies relating
to the  Supplemental  Modules.  The  obligations  under this  Section 3(b) shall
survive any termination of this Agreement.

      (c) Sweetheart  shall keep  EarthShell  reasonably  apprised on a calendar
quarter basis of, and shall provide EarthShell with such documentation as it may
reasonably request  evidencing,  the number of Modules ordered and the number of
Modules and Lines installed by Sweetheart,  the cancellation or deferment of any
prior  purchase  orders for the  Modules  and the  reasons  therefor,  the Plant
Facilities  where the  Modules  had been  installed,  the  estimated  production
capability  of the  Modules  ordered  and not yet  delivered  and the  estimated
production capability of the Modules and Lines actually installed, the number of
Products  actually  manufactured  and  distributed  during the quarterly  period
covered by the  report  and the  approximate  purchase  price for the  Equipment
ordered as of the date of the report and the  purchase  price for the  Equipment
that had been installed as of the date of the report.

      (d)  Notwithstanding   anything  contained  in  this  Agreement,   whether
expressed or implied,  it is  unconditionally  and irrevocably  acknowledged and
agreed that (i)  Sweetheart  shall have no  liability  or  obligation  to order,
purchase,  install,  operate or use Modules,  Lines or other Equipment and/or to
manufacture and/or to promote, advertise, use, sell, offer to sell, import into,
distribute  or otherwise  dispose of the Products  within all or any part of the
Market  Segment or within the  Territory,  and  EarthShell's  sole and exclusive
remedy at law,  in  equity,  under  this  Agreement  or  otherwise  in the event
Sweetheart in its sole discretion, for any reason or for no reason elects not to
undertake  all or any of the  foregoing,  or  fails  to  meet  any or all of the
Milestones  is to  terminate  the  exclusivity  rights or, only in the case of a
failure to meet the  Milestones  set forth in Section  13(d),  to terminate this
Agreement  (in  each  case,  a  "MILESTONE  FAILURE").  In  furtherance  of  the
foregoing,  EarthShell hereby irrevocably waives and releases Sweetheart and its
affiliates and their  respective  shareholders,  officers and directors from any
and all claims,  causes of action or demands that arise solely with respect to a
Milestone  Failure,  whether  pursuant to breach of contract,  tort or any other
legal theory.  The  provisions of this Section 3(d) shall survive the expiration
or sooner termination of this Agreement.

      (e)  Sweetheart  shall  maintain  and  operate the lines of  Equipment  in
material compliance with all legal and administrative code standards  applicable
to the Equipment throughout the term of this Agreement.

      (f) Sweetheart,  upon reasonable advance notice from EarthShell and during
normal business hours, will permit EarthShell personnel or consultants access to
the Plant  Facilities  as is  reasonably  necessary in order for them to fulfill
EarthShell's  obligations or protect or enforce its rights under this Agreement.
Prospective  or  existing   licensee/sublicensee   joint  venture   partners  of
EarthShell will be permitted to have reasonable  access to the Plant Facilities,
upon  reasonable  advance notice by EarthShell and during normal business hours,
for the purpose of observing the Plant Facilities in operation.  Notwithstanding
the foregoing, Sweetheart will have no obligation to provide access to any 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 the EarthShell products.

      (g) The list of the current Certified Equipment Vendors is attached hereto
as  Exhibit D.  EarthShell  shall  provide  Sweetheart  with an updated  list of
Certified Equipment Vendors from time to time and upon Sweetheart's  request. At
Sweetheart's  request,  EarthShell shall not unreasonably  withhold or delay its
consent  to  license  or  certify  other  equipment   vendors  on  licensing  or
certification  terms and conditions  that are not materially  different from the
terms and conditions  offered to the then existing  Certified  Equipment Vendors
(subject to any restrictions in the  certification or licensing  agreements with
the then existing Certified  Equipment  Vendors).  To the extent that EarthShell
can  do so  without  violating  any  confidentiality  undertakings  that  may be
applicable, EarthShell will cooperate in providing Sweetheart with copies of any
agreements into which EarthShell enters with any Certified Equipment Vendors.

4.    EC PROFIT DISTRIBUTION.

      (a) During the term of this Agreement,  Sweetheart shall pay to EarthShell
an amount (the "EC PROFIT  DISTRIBUTION")  equal to twenty  percent (20%) of the
Net Sales of Products by Sweetheart, if any (other than Net Sales of Products to
Third-Party  Sublicensees  for sale to  their  customers).  Notwithstanding  the
foregoing,  but subject to Section  4(d),  in view of  Sweetheart's  anticipated
start-up  costs,  the EC  Profit  Distribution  shall be (i)  adjusted  by fifty
percent  (50%) to ten percent  (10%) of Net Sales  during the twelve  (12)-month
period  following  the earlier of (A) June 30, 2003,  and (B) the date the Plate
Line is installed at a Plant Facility,  meets the Required Specifications and is
accepted by Sweetheart  (which  acceptance  shall not be unreasonably  declined)
(the "START DATE"),  and (ii) adjusted by  twenty-five  percent (25%) to fifteen
percent (15%) of Net Sales during the period commencing on the day following the
first anniversary of the Start Date and terminating on the second anniversary of
the Start Date.

      (b)  Following  the second  anniversary  of the Start Date,  the EC Profit
Distribution  will be restored to twenty  percent  (20%) of Net Sales;  provided
that the EC Profit Distribution shall be reduced to fifteen percent (15%) of Net
Sales if, by the end of the second  anniversary  of the Start  Date,  EarthShell
does not  provide  to  Sweetheart  at least one  qualified  vendor who agrees to
provide film for Sweetheart's reasonably projected volume of Products at a price
that is at least 25% less per pound than the quoted  price (FOB U.S.  vendor) of
film made from 100% virgin  materials.  Such price quotes shall be predicated on
(i) the film having 50%  recycled  content,  (ii) the recycled  materials  being
furnished at zero cost to the vendor,  and (iii) Sweetheart  agreeing to provide
to such  vendor,  and such vendor  agreeing to accept  from  Sweetheart,  all of
Sweetheart's  film scrap material,  and Sweetheart  further agreeing to purchase
from such vendor all or  substantially  all of the film to be used by Sweetheart
to manufacture the Products under a long-term supply contract.


                                       11

      (c)  Notwithstanding  anything in Section 4(b) to the  contrary,  upon the
sale or distribution by any existing or future  sublicensee of EarthShell of any
Product   within  any  Market  Segment  within  the  Territory  and  during  the
Exclusivity  Period  under a right  to do so  granted  under  the  terms  of any
existing or future license or sublicense agreement to which EarthShell or any of
its  predecessor or successor  entities is a party,  then, upon the later of the
second  anniversary of the Start Date, or the date of such sale or distribution,
and until the end of the Exclusivity Period, the EC Profit Distribution shall be
reduced  to ten  percent  (10%)  of Net  Sales  (it  being  recognized  that the
reduction in the EC Profit  Distribution shall not limit the rights and remedies
Sweetheart may have, in law or equity,  under this Agreement or otherwise,  with
respect to  EarthShell's  intentional  misconduct in granting future licenses or
sublicensees to third parties in derogation of Sweetheart's  rights  hereunder).
In this regard, EarthShell covenants to use its reasonable best efforts (without
paying any sum) to terminate the rights of the sublicensees  listed in Exhibit E
to sell Products within the Market Segments and within the Territory  during the
Exclusivity Period.

      (d) Notwithstanding anything to the contrary in this Agreement, during the
Exclusivity Period, the total EC Profit Distribution  payable with regard to the
Net  Sales of  clamshell  or other  hinged  sandwich  containers  to  McDonald's
Corporation  (or to Perseco or any other  purchasing  agent which purchases such
Products for ultimate  sale or use by customers of McDonald's  Corporation)  for
all calendar  years  following  the  Effective  Date shall not exceed 50% of the
McDonald's  Contribution  Margin  achieved by Sweetheart with regard to such Net
Sales during such calendar years, determined on a cumulative basis.

      (e)  Within  thirty  (30) days of the last day of each  month,  Sweetheart
shall pay to EarthShell  the EC Profit  Distribution  in respect of all Products
shipped and invoiced by  Sweetheart  during such month,  if any. Each payment of
the EC  Profit  Distribution  shall be  accompanied  by a  written  report  (the
"REPORT")  prepared by Sweetheart  and  certified as materially  accurate by the
Chief Financial Officer or Treasurer of Sweetheart. Each Report shall set forth,
for the month  covered by the  Report,  (i) the  number of each of the  Products
shipped by  Sweetheart,  (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.

      (f) Notwithstanding anything to the contrary in this Agreement, Sweetheart
shall have the right to meet a Net Sales  Milestone  for a  particular  calendar
quarter  or year (as is  specified  in Exhibit  C) by paying to  EarthShell  the
difference  between the total EC Profit  Distribution that EarthShell would have
received  had the Net  Sales  Milestone  been met and the  amount  of EC  Profit
Distribution  actually received by EarthShell for such calendar quarter or year,
such  amount  to be  paid  within  sixty  (60)  days  following  the  end of the
applicable  calendar  quarter  or year  (there  shall be no cure  period for the
failure to make this payment).

      (g) All payments of the EC Profit  Distribution  due under this  Agreement
shall be calculated and paid by Sweetheart in United States dollars.

      (h) If Sweetheart fails to make a timely payment due under this Section 4,
interest at an annual rate equal to twelve percent (12%),  compounded  annually,
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.


                                       12
<PAGE>


      (i) Any failure to pay any EC Profit  Distribution within thirty (30) days
following the date  Sweetheart  receives  notice from  EarthShell that it is due
shall constitute a material breach for purposes of Section 13(b) hereof.

5.    RIGHT TO AUDIT.

      (a) Sweetheart shall keep and maintain at its principal  executive offices
or at such other  locations  as the Parties  shall agree  complete  and accurate
records  concerning  the purchase  and  installation  of the Modules  (including
copies of the monthly reports referred to in Section 3(b) and the  documentation
supporting the  information  contained in such report),  the Net Sales generated
from the sale or  distribution  of the  Products  within any  particular  Market
Segment,  and the  McDonald's  Contribution  Margin,  to the extent  applicable.
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 Sweetheart relating to such Net Sales on a quarterly basis during the
term of this Agreement  during normal business hours and upon  reasonable  prior
notice to Sweetheart.

      (b) If  Sweetheart  is  ultimately  determined  to have  failed  to pay to
EarthShell all of the EC Profit Distributions actually due hereunder, Sweetheart
shall  promptly  pay the full amount of such  discrepancy  to  EarthShell,  with
interest  thereon,  at an annual rate equal to twelve percent (12%),  compounded
annually;  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 an EC  Profit  Distribution  payment  due
hereunder in excess of five percent (5%), then all costs and expenses related to
such audit shall be reimbursed  to  EarthShell by Sweetheart  within thirty (30)
days of the completion of such credit.

      (c) If Sweetheart is ultimately  determined to have overpaid EarthShell an
EC Profit Distribution payment actually due hereunder, EarthShell shall promptly
pay the full amount of the overpayment to Sweetheart,  with interest thereon, at
an annual rate equal to twelve percent  (12%),  compounded  annually,  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
(but, if developed for EarthShell,  only to the extent the third-party agreement
permits  EarthShell to sublicense the Improvement  without  restriction or cost)
(the "EARTHSHELL Improvements"), and, subject to any third-party agreements, all
Improvements developed by or for a licensee,  sublicensee,  or other contracting
party of EarthShell  ("SUBLICENSEE  IMPROVEMENTS").  All EarthShell Improvements
shall be included in the  Technology  licensed  hereunder to Sweetheart  without
additional  royalty or other obligation being imposed on Sweetheart.  Sweetheart
shall  have no right by virtue of this  Agreement  to  utilize  the  Sublicensee
Improvements  and the  Sublicensee  Improvements  shall not be  included  in the
Technology licensed hereunder to Sweetheart.


                                       13
<PAGE>


      (b)  Sweetheart  will own all  Sweetheart  Improvements  and  shall not be
obligated to allow EarthShell or any of its licensees or sublicensees to utilize
such Sweetheart Improvements. Sweetheart may utilize all Sweetheart Improvements
in any  commercial  activity,  except that during the term of this Agreement and
following the  termination  of this  Agreement,  Sweetheart  may not utilize the
Sweetheart   Improvements  to  manufacture   biodegradable   foam  food  service
disposable  packaging  that competes with the Products  sold or  distributed  by
EarthShell or its licensees or sublicensees.

      (c) Improvements  developed  jointly by EarthShell and Sweetheart  ("JOINT
IMPROVEMENTS")  shall be owned by EarthShell.  All Joint  Improvements  shall be
included in the Technology  licensed  hereunder to Sweetheart without additional
royalty or other obligation being imposed on Sweetheart. Sweetheart 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) Each Party that develops or acquires a material Improvement during the
term hereof will disclose such Improvement to the other Party promptly after the
development or acquisition of such Improvement by such Party, and, to the extent
such  Improvement  is  not  licensed  to  Sweetheart  or  EarthShell  (or  their
respective  licensees or sublicensees)  pursuant to the terms of this Section 6,
then, at the request of the other Party, the developing or acquiring Party shall
enter into good faith negotiations to allow the other Party (or its licensees or
sublicensees)  to utilize  such  Improvement  under  such terms and  conditions,
including  royalty  obligations,   as  are  commercially  reasonable  under  the
circumstances and such other additional  restrictions and financial  obligations
as may be imposed by any third party developing the Improvement in question,  it
being  understood  that,  in the event the  Parties  cannot  come to terms  with
respect to the utilization of such Improvement  despite their good faith efforts
to negotiate commercially reasonable terms to do so, the acquiring or developing
Party shall have no further  obligation  to allow the other Party to utilize the
Improvement.

7.    PATENT MATTERS.

      (a)  EarthShell  shall  have the  right,  in its sole  discretion,  to (i)
affirmatively seek patent protection for any EarthShell Improvement, Sublicensee
Improvement  or Joint  Improvement at its sole cost and expense or (ii) maintain
any such Improvement as a trade secret;  provided that such Improvement shall be
maintained  as a trade  secret  during the  pendency of any patent  application.
Sweetheart  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 this
Section 7(a),  including the execution of any documents  necessary to obtain and
maintain such patent protection.

      (b)  Sweetheart  shall  have the  right,  in its sole  discretion,  to (i)
affirmatively seek patent protection for any Sweetheart  Improvement at its sole
cost and expense or (ii)  maintain any such  Sweetheart  Improvement  as a trade
secret; provided that such Sweetheart Improvement shall be maintained as a trade
secret during the pendency of any patent  application.  EarthShell shall provide
Sweetheart,  at Sweetheart's  expense, with such assistance as may be reasonably
requested,  from  time to  time,  in  connection  with  efforts  to seek  patent
protection  for any  Sweetheart  Product  Improvement  in  accordance  with this
Section 7(b),  including the execution of any documents  necessary to obtain and
maintain such patent protection.


                                       14
<PAGE>


8.    INFRINGEMENT MATTERS.

      (a) Each of EarthShell  and  Sweetheart  will  promptly,  and in any event
within  thirty (30) days of actual  discovery,  notify the other of any apparent
infringement  of the  Technology in the  Territory  which comes to its attention
while this  Agreement  remains in effect.  Except with  respect to a  Sweetheart
Improvement,  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;  provided  that,  if
Sweetheart  shall have requested that EarthShell  pursue an infringement  action
against an apparent  infringer of the  Technology  within the Market Segment and
within the Territory,  and EarthShell fails to notify  Sweetheart  within thirty
(30) days  following  such  request,  of its  election to pursue and  diligently
prosecute any action against such apparent infringer,  Sweetheart shall have the
right to bring such action  against such  infringer;  provided  that  Sweetheart
agrees that  EarthShell may intervene,  at its sole cost and expense at any time
in such action, and, if it does intervene,  EarthShell shall control such action
in  all  respects,   including,   without  limitation,  with  respect  to  claim
construction   issues  and  the  assertion  of  an  invalidity  defense  by  the
infringement defendant. Except in the case of an infringement action relating to
an EarthShell Improvement or a Joint Improvement,  to the extent Sweetheart does
pursue an action  against an apparent  infringer  pursuant to this Section 8(a),
Sweetheart  shall be entitled to withhold EC Profit  Distribution  payments from
EarthShell  under this Agreement to the extent necessary to reimburse it for all
reasonable,   third-party,   out-of-pocket  costs  (including  attorneys'  fees)
actually paid by Sweetheart and directly  related to the pursuit of such action.
Any such withheld EC Profit  Distribution  payments shall be deemed paid for the
purpose of determining whether Sweetheart has achieved its Milestones.

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

      (c) Sweetheart shall promptly notify EarthShell of (i) any claim or to its
knowledge  threatened  claim by any Person that the use of the Technology or any
part thereof by Sweetheart in connection  with the  manufacture,  use or sale of
any Product by  Sweetheart  or any  Customer  infringes  or violates the patent,
trade  secret  or other  intellectual  property  rights  of such  Person  in the
Territory or any part thereof and (ii) the  commencement  of any lawsuit against
Sweetheart,  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.  Sweetheart
will assist EarthShell in the defense of any EarthShell  Infringement  Action by
providing such  information,  fact witnesses and other cooperation as EarthShell
may  reasonably  request  from  time to time;  provided  that  EarthShell  shall
reimburse  Sweetheart for any reasonable,  third-party,  out-of-pocket  expenses
incurred by Sweetheart in connection therewith.  Sweetheart 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,  Sweetheart  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  Sweetheart  so  assumes  the  defense  of  an  EarthShell
Infringement  Action,  Sweetheart  shall have no right to settle such EarthShell
Infringement  Action  unless  Sweetheart  shall have  received the prior written
consent of EarthShell which shall not be unreasonably withheld or delayed.


                                       15
<PAGE>


      (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 Market  Segments and within the Territory and  requiring  Sweetheart  (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 Sweetheart,
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  Sweetheart'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 the
following obligations hereunder:

      (a)  EarthShell has heretofore  provided to  Sweetheart,  at  EarthShell's
cost, each of the following items as they existed as of September 15, 2002:

            (i) technical and engineering specifications and typical engineering

            (iv) detailed mix designs and process  parameters for  manufacturing
the Products.

      (b) EarthShell  shall, at Sweetheart's  reasonable  request and subject to
Sweetheart  reimbursing  EarthShell  for its  out-of-pocket  costs,  provide  to
Sweetheart  technical  support,  including  assisting  Sweetheart in revising or
modifying any of the items referred to in Section 9(a),  training the Sweetheart
employees to operate the  Equipment  and  manufacture  and package the Products,
installing  the  Equipment,  and  providing  direct  engineering,   design,  and
debugging  services to Sweetheart in connection  with the operation of the Plant
Facilities.  EarthShell's  reimbursable  costs shall  include  all direct  costs
incurred in performing the related services,  including the allocable portion of
the  standard  hourly  rates or  other  compensation  and  benefits  payable  to
personnel involved with the project, the cost of supplies and raw materials, and
a reasonably allocable share of EarthShell's indirect costs and overhead.


                                       16
<PAGE>


      (c)  During the term of this  Agreement,  EarthShell  shall,  at its cost,
timely  take all steps  reasonably  necessary,  including  the payment of patent
maintenance  fees, to maintain the existence of all Licensed  Patents within the
Market  Segments  and within  the  Territory,  but only to the  extent  that the
failure to maintain a Licensed Patent would materially  adversely affect the Net
Sales  Sweetheart is reasonably  anticipated  to achieve during the term of this
Agreement.

      (d)  EarthShell  shall satisfy the EarthShell  Purchase  Obligation to the
extent  required  under  Section  3(b),   which  obligation  shall  survive  the
expiration or sooner termination of this Agreement.

10.   OTHER DUTIES AND OBLIGATIONS OF SWEETHEART.

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

      (a) Subject to Section  2(d),  Sweetheart  shall  prominently  display and
utilize such  Trademarks  (whether owned by or licensed to EarthShell) as may be
designated by EarthShell from time to time in connection with the 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,  Sweetheart shall use its reasonable efforts to cause each
Product  manufactured  by  Sweetheart  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).  Sweetheart  shall not in any manner
represent that it has any ownership interest any Trademarks  licensed hereunder.
Sweetheart  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 Sweetheart shall inure to the benefit of EarthShell. Sweetheart shall
reasonably  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,  Sweetheart 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,  Sweetheart  shall  have the right to
utilize for the manufacture and/or sale of Products existing stock and inventory
of raw materials, work in progress and manufactured Products for a period of one
(1) year,  provided  Sweetheart disposes of such existing stock and inventory in
as expeditiously a manner as is commercially reasonable under the circumstances.

      (c) To the  best  of  its  knowledge,  Sweetheart  acknowledges  that  the
Technology  in  existence  on the date  hereof is novel  and  unique in the food
service  disposable  products  industry.  Subject to the provisions of Section 8
hereof  and  EarthShell's   compliance  with  its  obligations  hereunder,   (i)
Sweetheart  shall not  challenge  or question  the  validity or ownership of the
Trademarks  or,  subject to the  provisions  of  applicable  law,  any  Licensed
Patents;  and (ii) Sweetheart 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;  provided,
however,  that,  to the extent  EarthShell  does not take all  reasonable  steps
necessary to defend such action  following a written request by Sweetheart to do
so, or EarthShell  does not give  Sweetheart  adequate  assurances  that it will
comply with its  obligations  under Section 8(d) in the event it is unsuccessful
in the defense of such  action,  then  Sweetheart  shall have the right to place
that  amount  of  payments  into  escrow as shall  reasonably  be  necessary  to
discharge its obligations to the party  challenging the validity of the Licensed
Patents (or claims thereof),  based on Sweetheart's reasonable estimation of the
likely outcome of the action and the obligations  that it will reasonably  incur
in respect of such party based on such likely outcome. Except as provided in the
immediately  preceding  sentence,  in the event  Sweetheart fails to continue to
make any payments owed to EarthShell  hereunder based upon or in connection with
such a challenge,  EarthShell  may at its option  terminate  this Agreement upon
notice to Sweetheart and Sweetheart's  failure to cure such  non-payment  within
the applicable cure period.

      (d) Sweetheart represents,  warrants and covenants to EarthShell that from
and after the Effective Date, and except to the extent  attributable to a breach
of warranty  provided to Sweetheart  by  EarthShell  or the Certified  Equipment
Vendor, (i) the Products manufactured and commercially sold by Sweetheart to all
Persons  (other than  intercompany  sales which do not  constitute  Gross Sales)
shall conform to all of the  specifications  provided by EarthShell  pursuant to
Section  9(a) and (ii)  Sweetheart  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) Sweetheart 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.  Sweetheart  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) Sweetheart  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) Sweetheart shall retain, and train,  suitably  qualified  employees to
operate  the  Equipment  and  manufacture  the  Products  and  shall  be  solely
responsible for the payment and discharge of any taxes,  duties, or withholdings
relating to any  transaction of Sweetheart 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) Subject to Section 4(b), Sweetheart grants EarthShell a right of first
offer to supply to Sweetheart all (but not less than all) of any category of raw
material  (e.g.,  starch)  necessary  to  manufacture  the  Products  (the  "RAW
MATERIALS").  Sweetheart shall regularly and routinely inform  EarthShell of all
of its  requirements for a category of Raw Material prior to purchasing the type
of Raw Material from any other Person, and, except for price, the material terms
on which Sweetheart proposes to purchase such Raw Materials, and EarthShell may,
at its option,  submit a bid or proposal  offer for the supply of the particular
Raw Material,  provided such bid or offer is submitted to Sweetheart  within ten
(10) days  following the request for same. If EarthShell  timely  submits such a
bid or offer to  supply  all (but not  less  than  all) of the  category  of Raw
Material  requested by Sweetheart  ("OFFERED RAW  MATERIALS"),  Sweetheart shall
have the right, exercisable in its sole discretion,  to (i) elect to accept such
bid or offer for Raw  Materials,  or (ii) pursue bids or offers from other third
parties in which event  Sweetheart  shall be free to enter into purchase  orders
for such Raw Materials,  provided such orders or other  agreements are on terms,
including  price,  quality  assurances  and  delivery  dates,  that  are no less
favorable to Sweetheart than those offered or proposed by EarthShell.

11.   REPRESENTATIONS AND WARRANTIES OF EARTHSHELL.

      (a)  EarthShell   hereby   represents  and  warrants  to  Sweetheart  that
EarthShell has a valid and enforceable  exclusive  license to use the Technology
to manufacture,  distribute and sell the Products in the Territory and the right
to sublicense  the  Technology to Sweetheart as set forth in this  Agreement and
that except as expressly set forth in this  Agreement,  there are no outstanding
assignments, security interests, licenses or agreements, either written or oral,
or implied, as would affect or be in derogation of the license granted hereunder
(except as set forth on Exhibit E and except for the EKI Agreement).  EarthShell
further warrants that it has no present knowledge that any Technology  infringes
or is claimed to infringe any patent or other proprietary  rights of others, and
that all of the Licensed Patents have been duly filed (or their applications are
pending),  and,  except for the pending  patent  applications,  are currently in
force.  EarthShell  covenants that any Patent owned or licensed to EarthShell as
of the  Effective  Date shall be deemed to  constitute a Licensed  Patent to the
extent such Patent is necessary to manufacture,  sell or distribute the Products
as contemplated under this Agreement. EarthShell further represents and warrants
that the only  sublicensees  that have previously been granted rights to utilize
the Technology to  manufacture,  sell or distribute  Products  within the Market
Segments and within the Territory, and whose sublicense agreements have not been
formally  terminated,  are the  Persons  listed  on  Exhibit E  attached  hereto
(although, view of the terms of the applicable sublicense agreements, EarthShell
does not believe  that such  Persons have any valid claims or rights to continue
to exploit the Technology to manufacture, sell or distribute Products within the
Territory).

      (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 SWEETHEART AND WHICH
ARE  BASED  UPON OR  UTILIZE  ANY OF THE  TECHNOLOGY;  AND (ii) IN REGARD TO ANY
SERVICES PROVIDED TO SWEETHEART BY EARTHSHELL HEREUNDER.

      (c) Nothing in this Agreement shall be construed as:

            (i) a warranty or representation by EarthShell as to the validity or
scope of any Licensed Patents (except as set forth in Section 11(a));


                                       19
<PAGE>


            (ii)  except  as set  forth in  Section  9(c),  a  requirement  that
EarthShell file any patent application, secure any patent or maintain any patent
in force;

            (iii)  except as and to the  extent  specifically  provided  herein,
conferring a right to use in  advertising,  publicity or otherwise any Trademark
of EarthShell; or

            (iv) granting by implication,  estoppel, or otherwise any license or
rights under patent or other  intellectual  property rights of EarthShell  other
than the Licensed Patents and other intellectual property rights included in the
Technology, to the extent sublicensed as provided in Section 2.

12.   NO CONSEQUENTIAL DAMAGES; LIMITATION OF LIABILITY.

      (a) EXCEPT AS  EXPRESSLY  SET FORTH IN THIS  AGREEMENT,  IN NO EVENT SHALL
EITHER PARTY BE LIABLE TO THE OTHER PARTY UNDER,  OR IN  CONNECTION  WITH,  THIS
AGREEMENT  FOR ANY  INDIRECT,  SPECIAL,  INCIDENTAL,  PUNITIVE OR  CONSEQUENTIAL
LOSSES, EXPENSES OR DAMAGES WHATSOEVER,  INCLUDING,  BUT NOT LIMITED TO, LOSS OF
REVENUE OR PROFITS, INCREASED COSTS OF PRODUCTION, DAMAGES OR LOSSES AS A RESULT
OF SUCH OTHER PARTY'S INABILITY TO OPERATE,  INABILITY TO FULFILL CONTRACTS WITH
THIRD PARTIES, OR SIMILAR MATTERS OR EVENTS ARISING FROM THE USE OR INABILITY TO
SELL THE  PRODUCTS  OR ANY  FAILURE  TO  FULFILL  A  PURCHASE  ORDER IN A TIMELY
FASHION.  The  limitations,  exclusions and  disclaimers in this Agreement shall
apply irrespective of the nature of the cause of the action or demand, including
but not  limited  to breach of  contract,  negligence,  tort or any other  legal
theory and shall survive any breach or breaches  and/or failure of the essential
purpose of this Agreement, or any remedy contained in this Agreement.

      (b) EXCEPT IN THE CASE OF EARTHSHELL'S INTENTIONAL MISCONDUCT IN BREACHING
ITS OBLIGATIONS UNDER SECTION 2(F) OF THIS AGREEMENT (IN WHICH CASE SWEETHEART'S
DAMAGES  RESULTING  THEREFROM WILL BE REDUCED BY THE  DIFFERENCE  BETWEEN THE EC
PROFIT  DISTRIBUTION  THAT WOULD HAVE BEEN  PAYABLE  UNDER  SECTION 4(A) HAD THE
BREACH NOT OCCURRED AND THE EC PROFIT  DISTRIBUTION  THAT IS THEN PAYABLE  UNDER
CLAUSE  (ii) OF  SECTION  4(A) AS A RESULT OF SUCH  BREACH),  OR ITS  FAILURE TO
TIMELY PERFORM ITS EARTHSHELL  PURCHASE  OBLIGATION UNDER SECTION 3.1(B),  IN NO
EVENT SHALL EARTHSHELL'S CUMULATIVE LIABILITY IN RESPECT OF CLAIMS ARISING UNDER
THIS AGREEMENT OR OTHERWISE RELATING TO THE USE, MANUFACTURE OR SALE OF PRODUCTS
(WHETHER  IN  CONTRACT,  TORT OR ANY  OTHER  THEORY  OF  LIABILITY)  EXCEED  THE
AGGREGATE  AMOUNT OF EC  PROFIT  DISTRIBUTION  THERETOFORE  PAID OR  PAYABLE  TO
EARTHSHELL HEREUNDER.  NOTWITHSTANDING THE FOREGOING OR ANYTHING TO THE CONTRARY
IN THIS AGREEMENT,  IN THE EVENT ANY EXISTING  EARTHSHELL  SUBLICENSEE  SELLS OR
DISTRIBUTES  PRODUCTS  DURING THE  EXCLUSIVITY  PERIOD TO ANY PERSON  WITHIN THE
MARKET SEGMENT AND WITHIN THE TERRITORY  UNDER A RIGHT TO DO SO SET FORTH IN THE
SUBLICENSE (OR SIMILAR)  AGREEMENT,  SWEETHEART'S SOLE REMEDY SHALL BE TO REDUCE
THE EC PROFIT DISTRIBUTION FROM TWENTY PERCENT (20%) TO TEN PERCENT (10%) AS SET
FORTH IN SECTION 4(A).

13.   TERM AND TERMINATION.

      (a) The term of this  Agreement  shall commence on the Effective Date and,
subject to earlier  termination  or extension as provided  herein and in Section
30, shall continue for a period of ten (10) years (the "INITIAL TERM") following
the Effective Date; provided that, upon the mutual agreement of the Parties, the
term of this Agreement may extend for renewal terms of additional periods of two
(2) years.  Notwithstanding  the  foregoing,  Sweetheart  has the right,  at its
option,  to extend the term of this Agreement,  for renewal terms of twenty-four
(24) months, provided that Sweetheart has generated at least $100 million in Net
Sales (or, alternatively,  has paid EarthShell an equivalent amount of EC Profit
Distributions)  during  the last  12-month  period of the  Initial  Term of this
Agreement,  and  Sweetheart  continues  to generate at least $100 million in Net
Sales (or,  alternatively,  pays  EarthShell an  equivalent  amount of EC Profit
Distributions)  during each  12-month  period  following  the  extension  of the
Initial Term (as determined on a cumulative basis, commencing with the first day
of the extended term of this Agreement).  To the extent Sweetheart fails to meet
these Net  Sales (or EC Profit  Distribution)  Milestones  during  any  12-month
period  following  the  extension of the Initial  Term,  EarthShell  may, at its
option,  terminate this Agreement  upon thirty (30) days' written  notice,  such
termination  to take effect no sooner than the end of the extended  term of this
Agreement.  Following the expiration or sooner  termination  of this  Agreement,
other than by reason of a material breach by Sweetheart,  Sweetheart will become
a Certified  Equipment Vendor under  substantially the same conditions and terms
as are applied to other similarly situated Certified Equipment Vendors.

      (b) Either Party may terminate this Agreement for a material breach by the
other  Party of the terms and  conditions  of this  Agreement  or the  Ancillary
Agreements  upon written notice to the breaching  party,  which is given no less
than thirty (30) days prior to an effective date of termination in the case of a
monetary  breach,  and sixty (60) days prior to an effective date of termination
in the case of a non-monetary  breach,  and which specifies in reasonable detail
the nature of such breach. If the breaching Party cures such breach prior to the
effective date of termination, this Agreement and the Ancillary Agreements shall
not terminate and will continue in full force and effect.

      (c)  Either  Party  may,  by giving  the  other  Party  written  notice of
termination,  immediately  terminate this Agreement  following the Bankruptcy of
the other Party.


                                       21
<PAGE>

      (d) Notwithstanding any provision of this Agreement to the contrary,  this
Agreement  shall  terminate,  at  either  EarthShell's  or  Sweetheart's  option
evidenced by its delivery of notice of termination  to the other Party,  if: (i)
on or before October 31, 2002,  Sweetheart  and/or  EarthShell fail to execute a
purchase  order with DTE, in form and content  satisfactory  to  EarthShell  and
Sweetheart,  in their sole discretion (A) obligating  Sweetheart to purchase the
Plate Line, and, subject to Section 3(b),  obligating  Sweetheart or EarthShell,
as the case may be, to purchase the Supplemental Modules (the Plate Line and the
Supplemental  Modules are  referred  to herein as the  "INITIAL  MODULES"),  (B)
requiring DTE to install and debug at a Plant  Facility,  on or before April 15,
2003, the Plate Line and, if purchased by Sweetheart,  the Supplemental Modules,
meeting all of the material  terms,  conditions  and  specifications,  including
performance  and efficiency  criteria,  set forth in the purchase orders for the
Plate Line and, if  purchased  by  Sweetheart,  the  Supplemental  Modules  (the
"REQUIRED  SPECIFICATIONS"),  (C)  permitting  Sweetheart  and/or  EarthShell to
cancel their  purchase  orders  without  penalty (and  permitting  EarthShell to
cancel the EarthShell  Purchase  Obligation without penalty) if (aa) the Parties
terminate  this  Agreement  pursuant  to  Section  13(e) as a result  of DTE not
meeting the Preliminary  Validation Date, or (bb) DTE fails to install and debug
the Initial  Modules meeting the Required  Specifications  at the Plant Facility
designated by Sweetheart (or EarthShell, as applicable),  on or before April 15,
2003;  through no fault of  Sweetheart,  (D) allowing  Sweetheart  to assign and
delegate to EarthShell or to  EarthShell's  designee,  without  penalty,  all of
Sweetheart's  rights  and  obligations  under  the  DTE  purchase  agreement  to
purchase, install and debug the Supplemental Modules in the event the EarthShell
Purchase Obligation is triggered pursuant to Section 3(b), and for Sweetheart to
be released from all liability thereunder, (E) providing for waxing and stacking
capability for each Product to be produced by the Initial  Modules;  or (ii) the
purchase  order  for  the  Plate  Line  is  terminated  by  Sweetheart,  or  the
installation  or debugging of the Plate Line is delayed  beyond May 15, 2003; or
(iii) Sweetheart fails to deliver commercially  acceptable Products to Customers
on or before June 30, 2003  (subject to extension as a result of a Force Majeure
Event). The Initial Modules shall be comprised of (aa) eight (8) Modules for the
purpose of producing plates (the "PLATE LINE"),  and (bb) up to seven additional
Modules,  as mutually agreed by the Parties,  having the capability of producing
the  McDonald's  Big Mac  clamshell  and a range of bowls and plates  (the seven
Modules,  as ultimately agreed to by the Parties,  are referred to herein as the
"SUPPLEMENTAL  MODULES").  For the avoidance of doubt,  Sweetheart shall have no
obligation  to finance or complete the purchase of the  Supplemental  Modules in
the event the EarthShell  Purchase  Obligation is triggered  under Section 3(b),
and in the event it is triggered,  EarthShell shall have the right to direct DTE
as to the place or places where the  Supplemental  Modules will be delivered and
installed.

      (e) Either Party may terminate this Agreement in the event DTE shall fail,
on or before  January 31,  2003,  as such date may be  mutually  extended by the
Parties  (such date, as it may be extended,  is referred to as the  "PRELIMINARY
VALIDATION  DATE"),  to  demonstrate,  to  the  reasonable  satisfaction  of the
Parties,  that the Initial  Modules are  reasonably  likely to meet the Required
Specifications  through  performance  and  efficiency  tests  run  on  a  sample
Module(s)  under  conditions  that are  reasonably  expected  to  replicate  the
conditions at the St. Thomas facility with respect to a fully  integrated  Line,
such  termination to be effected by the one Party giving the other Party written
notice of  termination  within (30) days  following the  Preliminary  Validation
Date.

      (f) Except as  expressly  provided in this  Agreement,  from and after the
Effective  Date  of  the  expiration  of  the  term  of  this  Agreement  or the
termination  of this  Agreement  pursuant to this Section 13 hereof,  Sweetheart
shall have no right,  whatsoever,  to utilize the Technology or Trademarks,  and
Sweetheart  shall promptly  return to EarthShell all written  materials or other
tangible media  containing any Trade Secrets which are then in the possession of
Sweetheart.  Sections 3(b), 4, 5, 6, 8, 10(g),  12, 13(d),  (e) and (f), 14, 15,
16,  17,  18,  19,  and 21 shall  survive  termination  of this  Agreement.  The
obligation of Sweetheart to pay to EarthShell the EC Profit Distribution for all
Products  actually  sold  by  Sweetheart  prior  to the  Effective  Date  of the
expiration or  termination  of this  Agreement  shall survive the  expiration or
termination of this Agreement.

14.   RELATIONSHIP OF THE PARTIES.

      This Agreement shall not create any partnership,  joint venture or similar
relationship  between  Sweetheart and EarthShell (except for income tax purposes
and solely for the purpose of  characterizing  the EC Profit  Distribution  as a
profit  distribution  and without adverse  consequences  to Sweetheart),  and no
representation to the contrary shall be made by either Party. Neither Sweetheart
nor  EarthShell  shall have any  authority to act for or on behalf of or to bind
the other in any fashion, and no representation to the contrary shall be made by

arising  under this  Agreement,  the  prevailing  party in such  litigation,  as
determined by the judicial or  administrative  body adjudicating such litigation
and resulting in a final  determination,  shall recover from the other Party its
reasonable attorneys fees and costs.

22.   COUNTERPARTS.

      This  Agreement  may  be  executed  in two or  more  counterparts,  and by
facsimile signature, 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  consent of the other  Party  (such
consent not to be unreasonably  withheld or delayed),  except in connection with
the sale,  exchange or transfer of all or substantially all of the assets of the
Party  to  a   non-affiliated   party   pursuant   to  a  merger,   combination,
reorganization, asset sale or similar event; provided that, in the event of such
merger,  combination,  etc. of Sweetheart,  EarthShell's  consent shall still be
required if the successor  party is not a major  packaging  manufacturer  with a
comparable reputation as Sweetheart.  Notwithstanding the foregoing,  Sweetheart
reserves  the  right to pledge  as  collateral  its  Equipment,  Raw  Materials,
finished and unfinished goods and inventory, the license to complete and/or sell
such goods and  inventory,  and any other  tangible  personal  property  used in
connection with the activities  contemplated  under this Agreement to any lender
who provides it with the funding  necessary to purchase the Equipment  and/or to
retrofit or improve the Plant  Facilities to comply with its  obligations  under
this  Agreement,  and  EarthShell  reserves the right to assign its rights under
this Agreement to EKI.

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,  and,  except for the Ancillary
Agreements,  contains the entire agreement  between the Parties in regard to the
subject matter hereof.

25.   FORCE MAJEURE.

      Neither  Party  shall be liable to the other  for  delays or  failures  in
performance  (including,  in the case of Sweetheart,  a failure to achieve a Net
Sales  Milestone  or a  Milestone  relating  to the  purchase,  installation  or
debugging of Equipment)  resulting from causes beyond the reasonable  control of
that Party,  including,  without  limitation,  acts of God, riots,  acts of war,
governmental regulations, labor strikes, failure of a Certified Equipment Vendor
to  timely   deliver,   install  or  debug   Equipment   meeting  the   Required
Specifications (despite Sweetheart being in compliance with all applicable terms
under the related  purchase order or agreement),  or a communication  or utility
failures (a "FORCE MAJEURE EVENT");  provided  performance will be excused under
this Section 25 for not more ninety (90) days after the  occurrence of the Force
Majeure Event in question.  Each Party shall use commercially reasonable efforts
to mitigate the effects of any such delays and failures, and each Party affected
by such an event shall resume performance under this Agreement immediately after
the delaying  cause ceases.  For the  avoidance of doubt,  the failure of DTE to
install and debug the Initial Modules meeting the Required  Specifications  at a
Plant  Facility on or before May 15, 2003 (time being of the  essence)  shall be
considered a Force  Majeure Event and shall  automatically  extend all Net Sales
and other Milestones by ninety (90) days.

26.   PRESS RELEASES.

      Neither  Party shall issue any press  releases,  or public  announcements,
concerning this Agreement or the transactions contemplated hereunder without the
prior  consent  of the other  Party,  which  consent  shall not be  unreasonably
withheld  or  delayed,  and which shall be given in all events if the release or
announcement  is required in order to comply with  applicable  law.  The Parties
have agreed to the wording of the press  releases to be issued by Sweetheart and
EarthShell,  respectively, in connection with the execution and delivery of this
Agreement.

27.   FURTHER ASSURANCES.

      Each Party  agrees on behalf of itself  and its  successors  and  assigns,
without  additional  consideration,  to  prepare,  execute,  acknowledge,  file,
record,  publish  and  deliver  in  good  faith  such  documents,  certificates,
statements,  agreements and instruments  within a reasonable period from receipt
of written  request  therefor  which are  reasonably  necessary or convenient to
consummate  the  transactions  contemplated  by this  Agreement or the Ancillary
Agreements  or to more  effectively  carry out the  purposes of this  Agreement.
Except as specifically  provided herein,  all such documents,  etc. executed and
delivered  by  the  Parties   hereto  shall  contain  such  terms,   conditions,
representations,  warranties  and covenants as are standard and customary  under
Delaware law to consummate the transaction to which such documents, etc. relate.
No Party shall be required to execute or deliver  any  document,  etc.  which is
contrary  to the  terms  or  conditions  of  this  Agreement  or  the  Ancillary
Agreements.

28.   THIRD PARTY BENEFICIARIES.

      Except as specifically set forth herein, this Agreement is not intended to
create any rights or  remedies in favor of any Person who is not a Party to this
Agreement, or in any way create any third-party beneficiary rights or remedies.

29.   EFFECT OF BANKRUPTCY PROCEEDINGS.

      (a)  Sweetheart  agrees  that,  if for any reason it becomes a debtor in a
case  under the U.S.  Bankruptcy  Code,  this  Agreement,  pursuant  to  Section
365(c)(1) of the U.S. Bankruptcy Code, is not, and shall not be, assumable under
Section 365 of the U.S.  Bankruptcy Code, it being agreed and acknowledged  that
applicable patent law would excuse EarthShell from accepting performance from or
rendering  performance to any entity other than Sweetheart,  whether or not this
Agreement prohibited or restricted assignment of rights or delegation of duties.
Accordingly,  pursuant to Section  365(e)(2) of the U.S.  Bankruptcy  Code, this
Agreement will  automatically  terminate upon Sweetheart  becoming a debtor in a
case under the U.S.  Bankruptcy Code,  notwithstanding the provisions of Section
365(e)(1) of the U.S. Bankruptcy Code.

      (b) The  Parties  agree  that  the  Technology  constitutes  "intellectual
property" as defined in the U.S Bankruptcy Code, and that the Sublicense granted
to  Sweetheart  under this  Agreement  is  entitled  to the  benefits of Section
ss.365(n) of the U.S. Bankruptcy Code.

30.   EARTHSHELL BOARD APPROVAL.

      This Agreement requires the approval of the EarthShell Board of Directors,
which approval shall be obtained,  if at all, within ten (10) days following the
Effective Date,  failing which Sweetheart shall have the right to terminate this
Agreement upon notice to EarthShell.

      IN WITNESS WHEREOF,  the Parties have caused this Agreement to be executed
and  delivered  by their  duly  authorized  representatives  upon the date first
herein written.

Pursuant to Section 25 of the Agreement to which this Exhibit C is attached, the
foregoing  calendar  quarters through the calendar year ending December 31, 2004
shall be extended by 90 days  following the occurrence of a Force Majeure Event.
