BORROWER:  EARTHSHELL CONTAINER CORP., A DELAWARE CORPORATION
           (TIN: 77-0322379)
           800 MIRAMONTE DR.
           SANTA BARBARA, CA 93109

PRINCIPAL AMOUNT:  $29,832.61
INTEREST RATE:  8.000%
DATE OF NOTE: OCTOBER 31, 1997

PROMISE TO PAY.  EarthShell Container Corp., a Delaware Corporation
("Borrower") promises to pay to Montecito Bank & Trust ("Lender"), or order,
in lawful money of the United States of America, the principal amount of
Twenty Nine Thousand Eight Hundred Thirty Two & 61/100 Dollars ($29,832.61),
together with interest at the rate of 8.000% on the unpaid principal balance
from October 31, 1997, until paid in full.

PAYMENT.  Borrower will pay this loan on demand, or if no demand is made, in
53 payments of $657.51 each payment and an irregular test payment estimated
at $657.49. Borrower's first payment is due November 5, 1997, and all
subsequent payments are due on the same day of each month after that.
Borrower's final payment will be due on April 5, 2002, and will be for all
principal and all accrued interest not yet paid. Payments include principal
and interest. The annual interest rate for this Note is computed on a 365/360
basis: that is, by applying the ratio of the annual interest rate over a year
of 360 days, multiplied by the outstanding principal balance, multiplied by
the actual number of days the principal balance is outstanding. Borrower will
pay Lender at Lender's address shown above or at such other place as Lender
may designate in writing. Unless otherwise agreed or required by applicable
law, payments will be applied first to accrued unpaid interest, then to
principal, and any remaining amount to any unpaid collection costs and late
charges.

PREPAYMENT.  Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by
Lender in writing, relieve Borrower of Borrower's obligation to continue to
make payments under the payment schedule. Rather, they will reduce the
principal balance due and may result in Borrower making fewer payments.

LATE CHARGE.  If a payment is 10 days or more late, Borrower will be charged
9.000% of the unpaid portion of the regularly scheduled payment or $9.00,
whichever is greater.

DEFAULT.  Borrower will be in default if any of the following happens:  (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when due any other term obligation, covenant, or condition contained in this
Note or any agreement related to this Note, or in any other agreement or loan
Borrower has with Lender. (c) Any representation or statement made or
furnished to Lender by Borrower or on Borrower's behalf is false or
misleading in any material respect either now or at the time made or
furnished. (d) Borrower becomes insolvent, a receiver is appointed for any
part of Borrower's property, Borrower makes an assignment for the benefit of
creditors, or any proceeding is commenced either by Borrower or against
Borrower under any bankruptcy or insolvency laws. (e) Any creditor tries to
take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with
Lender. (f) Any guarantor dies or any of the other events described in this
default section occurs with respect to any guarantor of this Note. (g) A
material adverse change occurs in Borrower's financial condition, or Lender
believes the prospect of payment or performance of the indebtedness is
impaired.

If any default, other than a default in payment, is curable and if Borrower
has not been given a notice of a breach of the same provision of this Note
within the preceding twelve (12) months, it may be cured (and no event of
default will have occurred) if Borrower, after receiving written notice from
Lender demanding cure of such default:  (a) cures the default within fifteen
(15) days; or (b) if the cure requires more than fifteen (15) days,
immediately initiates steps which Lender deems in Lender's sole discretion to
be sufficient to cure the default and thereafter continues and completes all
reasonable and necessary steps sufficient to produce compliance as soon as
reasonably practical.

LENDER'S RIGHTS.  Upon default, Lender may declare the entire unpaid
principal balance on this Note and all accrued unpaid interest immediately
due, without notice, and then Borrower will pay that amount. Upon Borrower's
failure to pay all amounts declared due pursuant to this section, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, increase the interest rate on this Note 5.000
percentage points. Lender may hire or pay someone else to help collect this
Note if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's
attorneys' fees and Lender's legal expenses whether or not there is a
lawsuit, including attorneys' fees and legal expenses for bankruptcy
proceedings (including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgment collection services.
Borrower also will pay any court costs, in addition to all other sums
provided by law. This Note has been delivered to Lender and accepted by
Lender in the State of California. If there is a lawsuit, Borrower agrees
upon Lender's request to submit to the jurisdiction of the courts of Santa
Barbara County, the State of California. Subject to the provisions on
arbitration, this Note shall be governed by and construed in accordance with
the laws of the State of California.

DISHONORED ITEM FEE.  Borrower will pay a fee to Lender of $18.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

RIGHT OF SETOFF.  Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's
accounts with Lender (whether checking, savings, or some other account),
including without limitation all accounts held jointly with someone else and
all accounts Borrower may open in the future, excluding however all IRA and
Keogh accounts, and all trust accounts for which the grant of a security
interest would be prohibited by law. Borrower authorizes Lender, to the
extent permitted by applicable law, to charge or setoff all sums owing on
this Note against any and all such accounts.

ARBITRATION.  Lender and Borrower agree that all disputes, claims and
controversies between them, whether individual, joint or class in nature,
arising from this Note or otherwise, including without limitation contract
and tort disputes, shall be arbitrated pursuant to the Rules of the American
Arbitration Association, upon request of either party. No act to take or
dispose of any collateral securing this Note shall constitute a waiver of
this arbitration agreement or be prohibited by this arbitration agreement.
This includes, without limitation, obtaining injunctive relief or a temporary
restraining order; invoking a power of sale under any deed of trust or
mortgage; obtaining a writ of attachment or imposition of a receiver; or
exercising any rights relating to personal property, including taking or
disposing of such property with or without judicial process pursuant to
Article 9 of the Uniform Commercial Code. Any disputes, claims, or
controversies concerning the lawfulness or reasonableness of any act, or
exercise of any right, concerning any collateral securing this Note,
including any claim to rescind, reform, or otherwise modify any agreement
relating to the collateral securing this Note, shall also be arbitrated,
provided however that no arbitrator shall have the right or the power to
enjoin or restrain any act of any party. Lender and Borrower agree that in
the event of an action for judicial foreclosure pursuant to California Code
of Civil Procedure Section 726, or any similar provision in any other state,
the commencement of such an action will not constitute a waiver of the right
to arbitrate and the court shall refer to arbitration as much of such action,
including counterclaims, as lawfully may be referred to arbitration. Judgment
upon any award rendered by any arbitrator may be entered in any court having
jurisdiction. Nothing in this Note shall preclude any party from seeking
equitable relief from a court of competent jurisdiction. The statute of
limitations, estoppel, waiver, laches, and similar doctrines which would
otherwise be applicable in an action brought by a party shall be applicable
in any arbitration proceeding, and the commencement of an arbitration
proceeding shall be deemed the commencement of an action for these purposes.
The Federal Arbitration Act shall apply to the construction, interpretation,
and enforcement of this arbitration provision.

GENERAL PROVISIONS.  This Note is payable on demand. The inclusion of
specific default provisions or rights of Lender shall not preclude Lender's
right to declare payment of this Note on its demand. Lender may delay or
forgo enforcing any of its rights or remedies under this Note without losing
them. Borrower and any other person who signs, guarantees or endorses this
Note, to the extent allowed by law, waive any applicable statute of
limitations, presentment, demand for payment, protest and notice of dishonor.
Upon any change in the terms of this Note, and unless otherwise expressly
stated in writing, no party who signs this Note, whether as maker, guarantor,
accommodation maker or endorser, shall be released from liability. All such
parties agree that Lender may renew or extend (repeatedly and for any length
of time) this loan, or release any party or guarantor or collateral or
impair, fail to realize upon or perfect Lender's security interest in the
collateral; and take any other action deemed necessary by Lender without the
consent of or notice to anyone. All such parties also agree that Lender may
modify this loan without the consent of or notice to anyone other than the
party with whom the modification is made.
