          1.   REPRESENTATIONS AND WARRANTIES.

               (a)  The Company represents and warrants to, and agrees with,
each International Underwriter as set forth below in this Section 1. Certain
terms used in this Section 1 are defined in Section 17 hereof.

                    (i)       The Company has filed with the Securities and
     Exchange Commission (the "Commission") a registration statement (file
     number 333-13287) on Form S-1, including related preliminary prospectuses,
     for the registration under the Act of the offering and sale of the
     Securities.  The Company may have filed one or more amendments thereto,
     including the related preliminary prospectuses, each of which has
     previously been furnished to you.  The Company will next file with the
     Commission either (A) prior to the Effective Date of such registration
     statement, a further amendment to such registration statement (including
     the form of final prospectus) or (B) after the Effective Date of such
     registration statement, final prospectuses in accordance with Rules 430A
     and 424(b)(1), (3) or (4).  In the case of clause (B), the Company has
     included in such registration statement, as amended at the Effective Date,
     all information (other than, at the option of the Company, Rule 430A
     Information) required by the Act and the rules thereunder to be included in
     such registration statement and the Prospectuses.  As filed, such amendment
     and form of final prospectuses, or such final prospectuses (the
     "Registration Statement"), shall contain all Rule 430A Information,
     together with all other such required information, and, except to the
     extent the International Representatives shall agree in writing to a
     modification, shall be in all substantive respects in the form furnished to
     you prior to the Execution Time or, to the extent not completed at the
     Execution Time, shall contain only such specific additional


                                          2
<PAGE>

     information and other changes (beyond that contained in the latest
     International Preliminary Prospectus) as the Company has advised you, prior
     to the Execution Time, will be included or made therein.

                    It is understood that two forms of prospectus are to be used
     in connection with the offering and sale of the Securities: one form of
     prospectus relating to the U.S. Securities, which are to be offered and
     sold to United States and Canadian Persons, and one form of prospectus
     relating to the International Securities, which are to be offered and sold
     to persons other than United States and Canadian Persons. The two forms of
     prospectus are identical except for the outside front cover page, the
     inside front cover page, the discussion under the headings "Underwriting"
     and "Subscription and Sale" and the outside back cover page.  Such form of
     prospectus relating to the U.S. Securities as first filed pursuant to
     Rule 424(b) after the Execution Time or, if no filing pursuant to
     Rule 424(b) is made, such form of prospectus included in the Registration
     Statement at the Effective Date, is hereinafter called the "U.S.
     Prospectus"; such form of prospectus relating to the International
     Securities as first filed pursuant to Rule 424(b) after the Execution Time
     or, if no filing pursuant to Rule 424(b) is made, such form of prospectus
     included in the Registration Statement at the Effective Date, is
     hereinafter called the "International Prospectus"; and the U.S. Prospectus
     and the International Prospectus are hereinafter collectively called the
     "Prospectuses."

                    (ii)      On the Effective Date, the Registration Statement
     did or will, and when the Prospectuses are first filed (if required) in
     accordance with Rule 424(b) and on the Closing Date (as defined herein) and
     on any date on which shares sold in respect of the Underwriters'
     over-allotment option are purchased, if such date is not the Closing Date
     (a "settlement date"), each Prospectus (and any supplements thereto) will,
     comply in all material respects with the applicable requirements of the Act
     and the rules thereunder; on the Effective Date and at the Execution Time,
     the Registration Statement did not or will not contain any untrue statement
     of a material fact or omit to state any material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading; and, on the Effective Date, each Prospectus, if not filed
     pursuant to Rule 424(b), will not, and on the date of any filing pursuant
     to Rule 424(b) and on the Closing Date and any settlement date, each
     Prospectus (together with any supplement thereto) will not, include any
     untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; PROVIDED,
     HOWEVER, that the Company makes no representations or warranties as to the
     information contained in or omitted from the Registration Statement, or the
     Prospectuses (or any supplement thereto) in reliance upon and in conformity
     with information furnished herein or in writing to the Company by or on
     behalf of any Underwriter through the Representatives specifically for
     inclusion in the Registration Statement or the Prospectuses (or any
     supplement thereto).

                    (iii)     The Company has been duly incorporated and is
     validly existing as a corporation in good standing under the laws of the
     jurisdiction in which it is


                                          3
<PAGE>

     chartered or organized with full corporate power and authority to own its
     properties and conduct its business as described in the Prospectuses, and
     is duly qualified to do business as a foreign corporation and is in good
     standing under the laws of each jurisdiction which requires such
     qualification.

                    (iv)      The Company's authorized equity capitalization is
     as set forth in the Prospectuses; the capital stock of the Company conforms
     in all material respects to the description thereof contained in the
     Prospectuses; the outstanding shares of Common Stock have been duly and
     validly authorized and issued and are fully paid and nonassessable; the
     Securities have been duly and validly authorized, and, when issued and
     delivered to and paid for by the Underwriters, will be fully paid and
     nonassessable; the Securities have been duly authorized for listing,
     subject to official notice of issuance and evidence of satisfactory
     distribution on The Nasdaq Stock Market's National Market (the "Nasdaq
     National Market"); the certificates for the Securities are in valid and
     sufficient form and, in all material respects, are duplicative of the
     specimen certificate filed as an exhibit to the Registration Statement; the
     holders of outstanding shares of capital stock of the Company are not
     entitled to preemptive or other rights to subscribe for the Securities,
     except which rights have been effectively satisfied or waived; and, except
     as set forth in the Registration Statement, the Company has not issued or
     granted any options, warrants or other rights to purchase, agreements or
     other obligations to issue, or issued or granted any rights to convert any
     obligations into or exchange any securities for, shares of capital stock of
     or ownership interests in the Company, except for any of the foregoing
     which have expired or terminated or which are otherwise no longer
     outstanding.

                    (v)       There is no franchise, contract or other document
     of a character required to be described in the Registration Statement or
     Prospectuses, or to be filed as an exhibit thereto, which is not described
     or filed as required; and the statements in the Prospectuses under the
     headings "Certain United States Federal Income Tax Considerations" and
     "Shares Eligible for Future Sale" fairly summarize the matters therein
     described.

                    (vi)      This Agreement has been duly authorized, executed
     and delivered by the Company and constitutes a valid and binding obligation
     of the Company enforceable in accordance with its terms.

                    (vii)     The Company is not and, after giving effect to the
     offering and sale of the Securities and the application of the proceeds
     thereof as described in the Prospectuses, will not be an "investment
     company" as defined in the Investment Company Act of 1940, as amended.

                    (viii)    No consent, approval, authorization, filing with
     or order of any court or governmental agency or body is required in
     connection with the transactions contemplated herein, except such as have
     been obtained under the Act and such as may be required under the blue sky
     laws of any jurisdiction inside or outside of 


                                          4
<PAGE>

     the United States in connection with the purchase and distribution of
     the Securities by the Underwriters in the manner contemplated herein and in
     the Prospectuses.

                    (ix)      Neither the issue and sale of the Securities nor
     the consummation of any other of the transactions contemplated herein nor
     the fulfillment of the terms hereof will conflict with, result in a breach
     or violation of or imposition of any lien, charge or encumbrance upon any
     property or assets of the Company pursuant to, (i) the charter or by-laws
     of the Company or (ii) the terms of any indenture, contract, lease,
     mortgage, deed of trust, note agreement, loan agreement or other agreement,
     obligation, condition, covenant or instrument to which the Company is a
     party or bound or to which its property is subject, or (iii) any statute,
     law, rule, regulation, judgment, order or decree applicable to the Company
     of any court, regulatory body, administrative agency, governmental body,
     arbitrator or other authority having jurisdiction over the Company or any
     of its properties.

                    (x)       No holders of securities of the Company have
     pre-emptive rights or the right to the registration of such securities
     under the Registration Statement, or if such rights exist, they have been
     validly and legally satisfied or waived and will not be violated by the
     transactions contemplated in this Agreement.

                    (xi)      The consolidated financial statements and
     schedules of the Company included in the Prospectuses and the Registration
     Statement present fairly in all material respects the financial condition,
     results of operations and cash flows of the Company as of the dates and for
     the periods indicated, comply as to form with the applicable accounting
     requirements of the Act and the rules and regulations thereunder and have
     been prepared in conformity with generally accepted accounting principles
     applied on a consistent basis throughout the periods involved (except as
     otherwise noted therein). The selected financial data set forth under the
     caption "Selected Financial Data" in the Prospectuses and Registration
     Statement fairly present, on the basis stated in the Prospectuses and the
     Registration Statement, the information included therein.

                    (xii)     No action, suit or proceeding by or before any
     court or governmental agency, authority or body or any arbitrator involving
     the Company or its property is pending or, to the best knowledge of the
     Company, threatened that (i) could reasonably be expected to have a
     material adverse effect on the performance of this Agreement or the
     consummation of any of the transactions contemplated hereby or (ii) could
     reasonably be expected to have a material adverse change in the condition
     (financial or otherwise), prospects, earnings, business or properties of
     the Company, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, except as set forth in or contemplated in
     the Prospectuses (exclusive of any supplement thereto) (a "Material Adverse
     Effect").

     are necessary to the conduct of its operations as presently conducted; the
     Company is not in

     governmental or regulatory authority applicable to it or is not in
     non-compliance with any term or condition of, or has failed to obtain and
     maintain in effect, any license, certificate, permit or other governmental
     authorization required for the ownership or lease of its property or the
     conduct of its business, which violation, non-compliance or failure would
     individually or in the aggregate have a Material Adverse Effect; and the
     Company has not received notice of any proceedings relating to the
     revocation or material modification of any such license, certificate,
     permit or other authorization.

                    (xiv)     The Company is not in violation or default of
     (i) any provision of its charter or by-laws, (ii) the terms of any
     indenture, contract, lease, mortgage, deed of trust, note agreement, loan
     agreement or other agreement, obligation, condition, covenant or instrument
     to which it is a party or bound or to which its property is subject, or
     (iii) any statute, law, rule or regulation, or any judgment, order or
     decree of any court, regulatory body, administrative agency, governmental
     body, arbitrator or other authority having jurisdiction over the Company or
     any of its properties, as applicable.

                    (xv)      Deloitte & Touche LLP, who have certified certain
     financial statements of the Company and delivered their report with respect
     to the audited consolidated financial statements and schedules included in
     the Prospectuses, are independent public accountants with respect to the
     Company within the meaning of the Act and the applicable published rules
     and regulations thereunder.

                    (xvi)     There are no transfer taxes or other similar fees
     or charges under Federal law or the laws of any state, or any political
     subdivision thereof, required to be paid in connection with the execution
     and delivery of this Agreement or the issuance by the Company or sale by
     the Company of the Securities.

                    (xvii)    The Company has filed all foreign, federal, state
     and local tax returns that are required to be filed or has requested
     extensions thereof (except in any case in which the failure so to file
     would not have a Material Adverse Effect) and has paid all taxes required
     to be paid by it and any other assessment, fine or penalty levied against
     it, to the extent that any of the foregoing is due and payable, except for
     any such assessment, fine or penalty that is currently being contested in
     good faith or as would not have a Material Adverse Effect.

                    (xviii)   No labor disturbance by or dispute with the

     result in a Material Adverse Effect.

     financial responsibility against such losses and risks and in such amounts
     as are prudent and customary in the businesses in which they are engaged;
     the Company has not been refused any insurance coverage sought or applied
     for; and the Company has no reason to believe that it will not be able to
     renew its existing insurance coverage as and when such

<PAGE>

     coverage expires or to obtain similar coverage from similar insurers as may

     Material Adverse Effect.

     authorizations and permits issued by the appropriate federal, state or
     foreign regulatory authorities necessary to conduct its businesses, and the
     Company has not received any notice of proceedings relating to the
     revocation or modification of any such certificate, authorization or permit

     or approval, except any such violation of law or regulation, failure to
     receive required permits, licenses or other approvals or failure to comply
     with the terms and conditions of such permits, licenses or approvals which
     would not, singly or in the aggregate, result in a Material Adverse Effect.

                    (xxii)    The Company maintains a system of internal
     accounting controls sufficient to provide reasonable assurance that
     (i) transactions are executed in accordance with management's general or
     specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability;
     (iii) access to assets is permitted only in accordance with management's

     claim; (e) there is no pending or, to the Company's knowledge, 
     threatened action, suit, proceeding or claim by others that the Company 
     infringes or otherwise violates any patent, trademark, copyright, trade 
     secret or other proprietary rights of others, and the Company is unaware 
     of any other fact which would form a reasonable basis for any such 
     claim; (f)  to the Company's knowledge, there is no Patent or published 
     Patent application which contains claims that infringe any Intellectual

     such Intellectual Property; and (g) to the Company's knowledge, there is 
     no prior art that may render any Patent licensed to the Company invalid 
     or any Patent application licensed to the Company unpatentable which has 
     not been disclosed to the Patent and Trademark Office.  The Company owns 
     the Intellectual Property or has the rights to the Intellectual Property 
     that is necessary to conduct its business as described in the

     (ii) does not intend to use any of the proceeds from the sale of the
     Securities hereunder to repay any outstanding debt owed to any affiliate of
     Salomon Brothers, Inc, Smith Barney Inc., Credit Suisse First Boston
     (Europe) Limited, or any other Underwriter, except for cumulative dividends
     and accrued interest payable upon redemption of the Company's Series A
     Cumulative Senior Convertible Preferred Stock.

     directly or indirectly, any other corporation or the capital stock of any
     other corporation.

                    (xxvi)    Except as disclosed in the Prospectuses, there are
     no contracts, agreements or understandings between the Company and any
     person that would give rise to a valid claim against the Company or any
     Underwriter for a brokerage commission, finder's fee or other like payment
     in connection with the Offering.

                    (xxvii)   Except as disclosed in the Prospectuses, the

     it, in each case free from liens, encumbrances and defects that would
     materially affect the value thereof or materially interfere with the use
     made or to be made thereof by it; and except as disclosed in the
     Prospectuses, the Company holds any leased real or personal property under
     valid and enforceable leases with no exceptions that would materially
     interfere with the use made or to be made thereof by them.

     claim against the Selling Stockholder, the Company or any Underwriter for a
     brokerage commission, finder's fee or other like payment in connection with
     the Offering.

                    (vii)     Neither the sale of the Securities being sold by
     such Selling Stockholder, nor the consummation of any other of the
     transactions herein contemplated by such Selling Stockholder, or the
     fulfillment of the terms hereof by such Selling Stockholder will conflict
     with, result in a breach or violation of, or constitute a default under any
     law or the charter or by-laws or trust documents of such Selling
     Stockholder or the terms of any indenture or other agreement or instrument
     to which such Selling Stockholder, or any of its subsidiaries is a party or
     bound, or any judgment, order or decree applicable to such Selling
     Stockholder, or any of its subsidiaries of any court, regulatory body,
     administrative agency, governmental body or arbitrator having jurisdiction

                    (viii)    Such Selling Stockholder has not distributed and
     will not distribute any prospectus or other offering material in connection
     with the offering and sale of the Securities.

                    (ix)      Such Selling Stockholder has reviewed the
     "Principal and Selling Stockholders" section of the Prospectuses and will
     comply with all agreements and satisfy all conditions on its part to be
     complied with or satisfied pursuant to this Agreement on or prior to the
     Closing Date and will advise one of its Attorneys and Smith Barney Inc.,
     prior to the Closing Date if any statement to be made on behalf of such
     Selling Stockholder contemplated hereunder would be inaccurate if made as
     of the Closing Date.

                    (x)       Such Selling Stockholder does not have, or has
     waived prior to the date hereof, any preemptive right, co-sale right or
     right of first refusal or other similar right to purchase any of the
     Securities that are to be sold by the Company or any of the other Selling
     Stockholders to the Underwriters pursuant to this Agreement; such Selling
     Stockholder does not have, or has waived prior to the date hereof, any
     registration right or other similar right to participate in the offering
     made by the Prospectuses, other than such rights of participation as have
     been satisfied by the participation of such Selling Stockholder in the
     transactions to which this Agreement relates in accordance with the terms
     of this Agreement; and such Selling Stockholder does not own any warrants,
     options or similar rights to acquire, and does not have any right or

     Registration Statement and the Prospectuses.

                    (xi)      Such Selling Stockholder has executed and
     furnished to the Company a letter substantially in the form of Exhibit A
     hereto addressed to the International Representatives, in which such
     Selling Stockholder has agreed that, until such date which is 270 days
     after the Closing Date, without the prior written consent of Salomon
     Brothers Inc, such Selling Stockholder will not, directly or indirectly,
     offer, sell, contract to sell, grant any option or warrant for the sale of,
     register, loan, pledge, grant any rights with respect to, or otherwise
     transfer or dispose of any shares of capital stock of the Company or
     securities convertible into or exchangeable or exercisable for, or any
     rights to purchase or acquire, such shares of capital stock, including,
     without limitation, Common Stock which now or hereafter may be deemed to be
     beneficially owned by such Selling Stockholder, subject to certain
     exceptions provided therein.  It is understood that as joint book-running
     managers Salomon Brothers Inc and Smith Barney Inc., on the one hand, and
     Credit Suisse First Boston Corporation, on the other hand, have agreed not
     to release the Company or any stockholders of the Company from any
     restriction on transactions relating to the Company's securities without
     the written consent of the other.

                    (xii)     Such Selling Stockholder will cooperate to the
     extent necessary to cause the Registration Statement or any post-effective
     amendment thereto to become effective at the earliest possible time.

                    (xiii)    Such Selling Stockholder has no reason to 
     believe that the Preliminary Prospectus dated February 24, 1998 
     contained any untrue statements of fact that would be considered 
     material by an investor or failed to contain material facts necessary to 
     make the statements contained therein, in light of the circumstances 
     under which they were made, not misleading; it being understood that such
     Selling Stockholder has neither verified, nor made any independent
     investigation, search or inquiry of, any facts or statements made in the
     Preliminary Prospectuses.

          2.   PURCHASE AND SALE.

               (a)  Subject to the terms and conditions and in reliance upon 
the representations and warranties herein set forth, the Company and each 
Selling Stockholder agrees, severally and not jointly, to sell to the 
International Underwriters the amount of International Underwritten 
Securities set forth opposite such person's name on Schedule II, and each 
International Underwriter agrees, severally and not jointly, to purchase from 
the Company and the Selling Stockholders, at a purchase price of $______ per 
share, the amount of the International Underwritten Securities set forth 
opposite such International Underwriter's name in Schedule I hereto.

               (b)  Subject to the terms and conditions and in reliance upon 
the representations and warranties herein set forth, each Contributing 
Stockholder hereby grants an option to the several International Underwriters 
to purchase, severally and not jointly, the amount of shares of the 
International Option Securities set forth opposite their name of Schedule III 
at the same purchase price per share as the International Underwriters shall 
pay for the International Underwritten Securities.  Said option may be 
exercised only to cover over-allotments in the sale of the International 
Underwritten Securities by the International Underwriters.  Said option may 
be exercised in whole or in part at any time (but not more than once) on or 
before the 30th day after the date of the International Prospectus upon 
written or telegraphic notice by the International Representatives to the 
Company and the Contributing Stockholders setting forth the number of shares 
of the International Option Securities as to which the several International 
Underwriters are exercising the option and the settlement date.  Delivery of 
certificates for the shares of International Option Securities by the Company 
and the Contributing Stockholders, and payment therefor to the Company and 
the Contributing Stockholders, shall be made as provided in Section 3 hereof. 
The maximum number of shares of the International Option Securities to be 
sold by the Company and the Contributing Stockholders is set forth in 
Schedule III hereof.  If for any reason any Contributing Stockholder fails or 
is unable to sell any portion of the International Option Securities set 
forth opposite their name in Schedule III hereof, the Company agrees to issue 
and sell to the International Underwriters such additional number of 
securities at the same purchase price per share as the International 
Underwriters shall pay for the International Underwritten Securities.  In the 
event that the International Underwriters exercise less than their full 
over-allotment option, the number of shares of the International Option 
Securities to be sold by each party listed on Schedule III shall be, as 
nearly as practicable, in the same proportion to each other as are the number 
of shares of the International Option Securities listed opposite their 
respective names on said Schedule III.  The number of shares of the 
International Option Securities to be purchased by each International 
Underwriter shall be the same percentage of the total number of shares of the 
International Option Securities to be purchased by the several International 
Underwriters as such International Underwriter is purchasing of the 
International Underwritten Securities, subject to such adjustments as you in 
your absolute discretion shall make to eliminate any fractional shares.

          3.   DELIVERY AND PAYMENT.  Delivery of and payment for the
International Underwritten Securities and the International Option Securities
(if the option provided for in


                                          14
<PAGE>

Section 2(b) hereof shall have been exercised on or before the third Business
Day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on
________________, 1998, or at such time on such later date not more than three
Business Days after the foregoing date as the International Representatives and
the U.S. Representatives shall designate, which date and time may be postponed
by agreement among the International Representatives, the U.S. Representatives,
the Company and the Selling Stockholders or as provided in Section 9 hereof
(such date and time of delivery and payment for the International Securities
being herein called the "Closing Date").  Delivery of the International
Securities shall be made to the International Representatives for the respective
accounts of the several International Underwriters against payment by the
several International Underwriters through the International Representatives of
the respective aggregate purchase prices of the International Securities being
sold by the Company and each of the Selling Stockholders to or upon the order of
the Company and the Selling Stockholders by wire transfer payable in same-day
funds to two separate accounts specified by the Company and one separate account
specified by the Selling Stockholders.  Delivery of the International
Underwritten Securities and the International Option Securities shall be made
through the facilities of The Depository Trust Company unless the International
Representatives shall otherwise instruct.

          Each Selling Stockholder will pay all applicable state transfer taxes,
if any, involved in the transfer to the several International Underwriters of
the International Securities to be purchased by them from such Selling
Stockholder and the respective International Underwriters will pay any
additional stock transfer taxes involved in further transfers.

          If the option provided for in Section 2(b) hereof is exercised after
the third business day prior to the Closing Date, the Contributing Stockholders
and the Company, if applicable, will deliver the International Option Securities
(at the expense of the Company) to the International Representatives, at 388
Greenwich Street, New York, New York, on the date specified by the International
Representatives (which shall be within three Business Days after exercise of
said option) and certificates for the International Option Securities in such
names and denominations as the International Representatives shall have
requested for the respective accounts of the several International Underwriters,
against payment by the several International Underwriters through the
International Representatives of the purchase price thereof to or upon the order
of the Contributing Stockholders and the Company, if applicable, by wire
transfer payable in same-day funds to one account specified by the Contributing
Stockholders and one account specified by the Company, if applicable.  If
settlement for the International Option Securities occurs after the Closing
Date, the Company and the Contributing Stockholders will deliver to the
International Representatives on the settlement date for the International
Option Securities, and the obligation of the International Underwriters to
purchase the International Option Securities shall be conditioned upon receipt
of, supplemental opinions, certificates and letters confirming as of such date
the opinions, certificates and letters delivered on the Closing Date pursuant to
Section 6 hereof.

          It is understood and agreed that the Closing Date shall occur
simultaneously with the "Closing Date" under the U.S. Underwriting Agreement,
and that the settlement date, if any, shall occur simultaneously with the
"settlement date" under the U.S. Underwriting Agreement.

          4.   OFFERING BY UNDERWRITERS.     It is understood that the 
several Underwriters propose to offer the International Securities for sale 
to the public as set forth in the International Prospectus.

          5.   AGREEMENTS.

               (a)  The Company agrees with the several Underwriters that:

                    (i)       The Company will use its best efforts to cause the
     Registration Statement, if not effective at the Execution Time, and any
     amendment thereto, to become effective.  Prior to the termination of the
     offering of the Securities, the Company will not file any amendment of the
     Registration Statement or supplement to the Prospectuses or any Rule 462(b)
     Registration Statement unless the Company has furnished you a copy for your
     review prior to filing and will not file any such proposed amendment or
     supplement to which you reasonably object.  Subject to the foregoing
     sentence, if the Registration Statement has become or becomes effective
     pursuant to Rule 430A, or filing of the Prospectuses is otherwise required
     under Rule 424(b), the Company will cause the Prospectuses, properly
     completed, and any supplement thereto to be filed with the Commission
     pursuant to the applicable paragraph of Rule 424(b) within the time period
     prescribed and will provide evidence satisfactory to the International
     Representatives of such timely filing.  The Company will promptly advise
     the International Representatives (A) when the Registration Statement, if
     not effective at the Execution Time, shall have become effective, (B) when
     the Prospectuses, and any supplement thereto, shall have been filed (if
     required) with the Commission pursuant to Rule 424(b) or when any Rule
     462(b) Registration Statement shall have been filed with the Commission,
     (C) when, prior to termination of the offering of the Securities, any
     amendment to the Registration Statement shall have been filed or become
     effective, (D) of any request by the Commission or its staff for any
     amendment of the Registration Statement, or any Rule 462(b) Registration
     Statement, or for any supplement to the Prospectuses or of any additional
     information, (E) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose and (F) of
     the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the initiation or threatening of any proceeding for such
     purpose.  The Company will use its best efforts to prevent the issuance of
     any such stop order or the suspension of any such qualification and, if
     issued, to obtain as soon as possible the withdrawal thereof.

                    (ii)      If, at any time when a prospectus relating to the
     Securities is required to be delivered under the Act, any event occurs as a
     result of which either of


                                          16

     the Prospectuses as then supplemented would include any untrue statement of
     a material fact or omit to state any material fact necessary to make the
     statements therein in the light of the circumstances under which they were
     made not misleading, or if it shall be necessary to amend the Registration
     Statement or supplement either of the Prospectuses to comply with the Act
     or the rules thereunder, the Company promptly will (i) prepare and file
     with the Commission, subject to the second sentence of paragraph (a) of
     this Section 5, an amendment or supplement which will correct such
     statement or omission or effect such compliance and (ii) supply any
     supplemented Prospectuses to you in such quantities as you may reasonably
     request.

                    (iii)     As soon as practicable, the Company will make
     generally available to its security holders and to the International
     Representatives an earnings statement or statements of the Company which
     will satisfy the provisions of Section 11(a) of the Act and Rule 158 under
     the Act.

                    (iv)      The Company will furnish to the International
     Representatives and counsel for the International Underwriters, without
     charge, signed copies of the Registration Statement (including exhibits
     thereto) and to each other International Underwriter and each Selling
     Stockholder a copy of the Registration Statement (without exhibits thereto)
     and, so long as delivery of a prospectus by an International Underwriter or
     dealer may be required by the Act or otherwise required, as many copies of
     each International Preliminary Prospectus and the International Prospectus
     and any supplement thereto as the International Representatives may
     reasonably request.  The Company will pay the expenses of printing or other
     production of all documents relating to the offering.

                    (v)       The Company will arrange, if necessary, for the
     qualification of the Securities for sale under the laws of such
     jurisdictions as the International Representatives may designate, will
     maintain such qualifications in effect so long as required for the
     distribution of the International Securities and will pay any fee of the
     National Association of Securities Dealers, Inc., in connection with its
     review of the offering.

                    (vi)      The Company will not, for a period of 270 days
     following the Execution Time, without the prior written consent of Salomon
     Brothers Inc and the International Representatives, offer, sell or contract
     to sell, or otherwise dispose of (or enter into any transaction which is
     designed to, or could be expected to, result in the disposition (whether by
     actual disposition or effective economic disposition due to cash settlement
     or otherwise) by the Company or any affiliate of the Company or any person
     in privity with the Company or any affiliate of the Company) directly or
     indirectly, or announce the offering of, any other shares of Common Stock
     or any securities convertible into, or exchangeable for, shares of Common
     Stock; PROVIDED, HOWEVER, that the Company may issue and sell Common Stock
     pursuant to any employee stock option plan, stock ownership plan or
     dividend reinvestment plan of the Company in effect at the


                                          17
<PAGE>

     Execution Time and the Company may issue Common Stock issuable upon the
     conversion of securities or the exercise of warrants outstanding at the
     Execution Time.

                    (vii)     For a period of 270 days following the Execution
     Time, the Company will not, without the prior written consent of Smith
     Barney Inc. and the U.S. Representatives, release or waive any of the
     obligations of its stockholders pursuant to any agreements between the
     Company and its stockholders which restrict the transfer, encumbrance,
     offer or disposal of the Company's securities.

               (b)  Each International Underwriter agrees that (i) it is not 
purchasing any of the International Securities for the account of a United 
States or Canadian Person, (ii) it has not offered or sold, and will not 
offer or sell, directly or indirectly, any of the International Securities or 
distribute any International Prospectus to any person inside the United 
States or Canada, or to a United States or Canadian Person, and (iii) any 
dealer to whom it may sell any of the International Securities will represent 
that it is not purchasing for the account of a United States or Canadian 
Person and agree that it will not offer or resell, directly or indirectly, 
any of the International Securities inside the United States or Canada, or to 
a United States or Canadian Person or to any other dealer who does not so 
represent and agree; PROVIDED, HOWEVER, that the foregoing shall not restrict 
(A) purchases and sales between the U.S. Underwriters on the one hand and the 
International Underwriters on the other hand pursuant to the Agreement 
Between U.S. Underwriters and International Underwriters, (B) stabilization 
transactions contemplated under the Agreement Between U.S. Underwriters and 
International Underwriters, conducted through Smith Barney Inc. (or through 
the U.S. Representatives and International Representatives) as part of the 
distribution of the Securities, and (C) sales to or through (or distributions 
of International Prospectuses or International Preliminary Prospectuses to) 
persons not United States or Canadian Persons who are investment advisors, or 
who otherwise exercise investment discretion, and who are purchasing for the 
account of a United States or Canadian Person.

               (c)  The agreements of the International Underwriters set forth
in paragraph (b) of this Section 5 shall terminate upon the earlier of the
following events:

                    (i)       a mutual agreement of the U.S. Representatives and
     the International Representatives to terminate the selling restrictions set
     forth in paragraph (b) of this Section 5 and in Section 5(b) of the U.S.
     Underwriting Agreement; or

                    (ii)      the expiration of a period of 30 days after the
     Closing Date, unless (A) the Representatives shall have given notice to the
     Company that the distribution of the International Securities by the
     International Underwriters has not yet been completed, or (B) the
     Representatives shall have given notice to the Company that the
     distribution of the U.S. Securities by the U.S. Underwriters has not yet
     been completed.  If such notice by the Representatives or the International
     Representatives is given, the agreements set forth in such paragraph
     (b) shall survive until the earlier of


                                          18
<PAGE>

     (1) the event referred to in clause (i) of this subsection (c) or (2) the
     expiration of an additional period of 30 days from the date of any such
     notice.

               (d)  Each International Underwriter severally represents and
agrees that:

                    (i)       it has not offered or sold and, prior to the
     expiry of six months from the closing of the offering of the International
     Securities, will not offer or sell any International Securities to persons
     in the United Kingdom, except to persons whose ordinary activities involve
     acquiring, holding, managing or disposing of investments (whether as
     principal or agent) for the purpose of their businesses or otherwise in
     circumstances which have not resulted in and will not result in an offer to
     the public in the United Kingdom within the meaning of the Public Offers of
     Securities Regulation 1995;

                    (ii)      it has complied and will comply with all
     applicable provisions of the Financial Services Act 1986 with respect to
     anything done by it in relation to the International Securities, in, from
     or otherwise involving the United Kingdom; and

                    (iii)     it has only issued or passed on, and will only
     issue or pass on, in the United Kingdom any document received by it in
     connection with the issue of the International Securities to a person
     described in Article 11(3) of the Financial Services Act 1986 (Investment
     Advertisements) (Exemptions) Order 1996, as amended, or a person to whom
     the document may otherwise lawfully be issued or passed on.

               (e)  Unless otherwise agreed to by the Representatives, each
Selling Stockholder agrees that, until such date which is 270 days after the
Closing Date, without the prior written consent of Salomon Brothers Inc and the
International Representatives, such Selling Stockholder will not, directly or
indirectly, offer, sell, contract to sell, grant any option or warrant for the
sale of, register, loan, pledge, grant any rights with respect to, or otherwise
transfer or dispose of any shares of capital stock of the Company or securities
convertible into or exchangeable or exercisable for, or any rights to purchase
or acquire, such shares of capital stock, including, without limitation, Common
Stock which now or hereafter may be deemed to be beneficially owned by such
Selling Stockholder, subject to certain exceptions provided therein.  It is
understood that as joint book-running managers Salomon Brothers Inc and Smith
Barney Inc., on the one hand, and Credit Suisse First Boston Corporation, on the
other hand, have agreed not to release any Selling Stockholder from any
restriction on transactions relating to the Company's securities without the
written consent of the other.  Each Selling Stockholder also agrees and consents
to the entry of stop transfer instructions with the Company's transfer agent
against the transfer of the securities held by such Selling Stockholder except
in compliance with this restriction.

obligations of the International Underwriters to purchase the International 
Underwritten

Securities and the International Option Securities, as the case may be, shall 
be subject to the accuracy of the representations and warranties on the part 
of the Company, EKI and the Selling Stockholders contained herein as of the 
Execution Time, the Closing Date and any settlement date pursuant to Section 
3 hereof, to the accuracy of the statements of the Company, EKI and the 
Selling Stockholders made in any certificates pursuant to the provisions 
hereof, to the performance by the Company, EKI and the Selling Stockholders 
of their respective obligations to be performed at or before the Closing Date 
and to the following additional conditions:

               (a)  If the Registration Statement has not become effective prior
to the Execution Time, unless the U.S. Representatives and the International
Representatives agree in writing to a later time, the Registration Statement
will become effective not later than (i) 6:00 PM New York City time on the date
of determination of the public offering price, if such determination occurred at
or prior to 3:00 PM New York City time on such date or (ii) 9:30 AM on the
Business Day following the day on which the public offering price was
determined, if such determination occurred after 3:00 PM New York City time on
such date; if filing of either of the Prospectuses, or any supplement thereto,
is required pursuant to Rule 424(b), the Prospectuses, and any such supplement,
will be filed in the manner and within the time period required by Rule 424(b);
and no stop order suspending the effectiveness of the Registration Statement
shall have been issued and no proceedings for that purpose shall have been
instituted or threatened.

               (b)  The Company shall have furnished to the International
Representatives and the Selling Stockholders the opinion of Gibson, Dunn &
Crutcher LLP, counsel for the Company, dated the Closing Date, to the effect
that:

                    (i)       The Company and has been duly incorporated and is
     validly existing as a corporation in good standing under the laws of
     Delaware, with full corporate power and authority to own its properties and
     conduct its business as described in the Prospectuses, and is duly
     qualified to do business as a foreign corporation and is in good standing
     under the laws of each jurisdiction which requires such qualification,
     except in jurisdictions in which the failure to be so qualified would not
     have a Material Adverse Effect, and, to the knowledge of such counsel after
     due inquiry, the Company has no subsidiaries;

                    (ii)      The Company's authorized equity capitalization is
     as set forth in the Prospectuses; the capital stock of the Company conforms
     in all material respects to the description thereof contained in the
     Prospectuses; the outstanding shares of Common Stock (including the
     Securities being sold hereunder by the Selling Stockholders) have been duly
     and validly authorized and issued and are fully paid and nonassessable; the
     certificates for the Securities are in valid and sufficient form; and, to
     the knowledge of such counsel after due inquiry, the holders of outstanding
     shares of capital stock of the Company are not entitled to preemptive or
     other rights to subscribe for the Securities, except which rights have been
     validly and legally satisfied or waived; and, except as set forth in the
     Prospectuses, to the knowledge of such counsel after due inquiry, no
     options, warrants or other rights to purchase, agreements or other
     obligations to


                                          20
<PAGE>

     issue, or rights to convert any obligations into or exchange any securities
     for, shares of capital stock of or ownership interests in the Company are
     outstanding, except for any of the foregoing which have expired or
     terminated or which are otherwise no longer outstanding or those set forth
     in the Registration Statement;

                    (iii)     Upon delivery of the shares of Common Stock of the
     Company pursuant to this Agreement and payment therefor as contemplated
     herein, the Underwriters will acquire good and marketable title to such
     shares of Common Stock free and clear of any lien, claim, security
     interest, or other encumbrance, restriction on transfer or other defect in
     title;

                    (iv)      To the knowledge of such counsel following due
     inquiry but without search of court or agency records, there is no pending
     or threatened action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company of a character required to be disclosed in the Registration
     Statement which is not adequately disclosed in the Prospectuses, and there
     is no franchise, contract or other document of a character required to be
     described in the Registration Statement or Prospectuses, or to be filed as
     an exhibit thereto, which is not described or filed as required; the
     descriptions contained in the Prospectuses under the heading "Certain
     United States Federal Income Tax Considerations" constitute fair summaries
     of those statutes and regulations discussed therein applicable to the
     offering of the Securities; and the statements in the Prospectuses under
     the heading "Shares Eligible for Future Sale" fairly summarize the matters
     therein described;

                    (v)       The Registration Statement has become effective
     under the Act; any required filing of the Prospectuses, and any supplements
     thereto, pursuant to Rule 424(b) has been made in the manner and within the
     time period required by Rule 424(b); to the knowledge of such counsel, no
     stop order suspending the effectiveness of the Registration Statement has
     been issued and no proceedings for that purpose have been instituted or
     threatened, and the Registration Statement and each of the Prospectuses
     (other than the financial statements and other financial information
     contained therein, as to which such counsel need express no opinion) comply
     as to form in all material respects with the applicable requirements of the
     Act and the rules thereunder; and the descriptions in the Registration
     Statement and the Prospectuses of statutes, legal and governmental
     proceedings and contracts and other documents are accurate and fairly
     present the information required to be shown; provided however, that such
     counsel may exclude descriptions of statutes and legal and governmental
     proceedings set forth in the Intellectual Property Portion (as defined in
     Section 6(c)(iv) below) and the Regulatory Portion (as defined in Section
     6(d)(i) below) of the Registration Statement and Prospectuses, and under
     the headings "Risk Factors--Environmental Perception of EarthShell 
     Products" and "Business--The EarthShell Solution--Environmental Impact" 
     of the Registration Statement and Prospectuses);


                                          21
<PAGE>

                    (vi)      This Agreement has been duly authorized, executed
     and delivered by the Company;

                    (vii)     The Company is not and, after giving effect to the
     offering and sale of the Securities and the application of the proceeds
     thereof as described in the Prospectuses, will not be an "investment
     company" as defined in the Investment Company Act of 1940, as amended;

                    (viii)    No consent, approval, authorization, filing with
     or order of any court or governmental agency or body is required on behalf
     of the Company in connection with the sale of the International Securities
     as contemplated herein, except such as have been obtained under the Act and
     such as may be required under the blue sky laws of any jurisdiction and the
     securities laws of any jurisdiction outside the United States in connection
     with the purchase and distribution of the Securities by the International
     Underwriters in the manner contemplated in this Agreement and in the
     Prospectuses;

                    (ix)      Neither the issue and sale of the Securities, nor
     the fulfillment of the terms hereof will conflict with, result in a breach
     or violation or imposition of any lien, charge or encumbrance upon any
     property or assets of the Company pursuant to, (i) the charter or by-laws
     of the Company or (ii) the terms of any indenture, contract, lease,
     mortgage, deed of trust, note agreement, loan agreement or other agreement,
     obligation, condition, covenant or instrument to which the Company is a
     party or bound or to which its property is subject which is listed as an
     exhibit to the Registration Statement or described in the Prospectuses, or
     (iii) any statute, law, rule, or regulation, or any judgment, order or
     decree applicable to the Company of any court, regulatory body,
     administrative agency, governmental body, arbitrator or other authority
     having jurisdiction over the Company or any of its properties, except for
     any violation, breach or imposition which would not have a Material Adverse
     Effect;

                    (x)       To the knowledge of such counsel after due
     inquiry, no holders of securities of the Company have rights to the
     registration of such securities under the Registration Statement except for
     such rights as are specified in (a) the Registration Rights Agreement dated
     February 28, 1995, (b) the Registration Rights Agreement dated September
     16, 1993, (c) the Agreement between EKI and Jimmy Argyropolous dated
     October 13, 1992, and (d) the Registration Rights Agreements between the
     Company, Eva Ein, Kenny Loggins and Barry DeVorzon dated April 23, 1993, in
     each of cases (a) through (d), which rights have been legally and validly
     satisfied or waived; and

                    (xi)      To such counsel's knowledge after due inquiry,
     there are no contracts or other documents of a character required to be
     filed as an exhibit to the Registration Statement or required to be
     described in the Registration Statement or Prospectuses that are not filed
     or described as required.



                                          22
<PAGE>

In addition, such opinion shall state that such counsel has participated in the
preparation of the Registration Statement and Prospectuses as counsel to the
Company.  Such participation included conferences with officers of the Company
and the Company's independent accountants, but did not include verification by
such counsel of the facts stated in the Registration Statement and the
Prospectuses and, therefore, would not necessarily reveal any material
misstatements of fact or omission to state a material fact.  On the basis of
such participation, nothing has come to such counsel's attention which causes
such counsel to believe that either the Registration Statement or the
Prospectuses (except for the financial statements and other financial
information contained therein as to which such counsel expresses no opinion) as
of their respective dates and as of the Closing Date contained any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the States of Delaware
(limited to the Delaware General Corporation Law only) and California or the
Federal laws of the United States, to the extent they deem proper and specified
in such opinion, upon the opinion of other counsel of good standing whom they
believe to be reliable and who are satisfactory to counsel for the International
Underwriters and (B) as to matters of fact, to the extent they deem proper, on
certificates of responsible officers of the Company and public officials.
Reference to the Prospectuses in this paragraph (b) include any supplements
thereto at the Closing Date.

               (c)  The Company shall have furnished to the International
Representatives and the Selling Stockholders the opinion of Workman, Nydegger &
Seeley, patent counsel for the Company, dated the Closing Date, to the effect
that:

                    (i)       EKI is listed on the records of the United States
     Patent and Trademark Office as the sole holder of record of each of the
     patents listed under the heading "U.S. Patents Held by the Company" on
     Schedule IV attached hereto (the "U.S. Patents") and each of the patent
     applications listed under the heading "U.S. Patent Applications Submitted
     by the Company" on Schedule V attached hereto (the "U.S. Applications").
     Such counsel knows of no claims of third parties to any ownership interest
     or lien with respect to any of the U.S. Patents or U.S. Applications that
     would conflict with the Company's License Rights under the Amended and
     Restated License Agreement.

                    (ii)      EKI is listed in the records of the appropriate
     foreign office as the sole holder of record of each of the foreign patents
     listed under the heading "Non-U.S. Patents Held by the Company" on Schedule
     VI hereof (the "Non-U.S. Patents") (collectively, the U.S. Patents and
     Non-U.S. Patents are referred to herein as the "Patents") and each of the
     foreign patent applications listed under the heading "Non-U.S. Patent
     Applications Submitted by the Company" on Schedule VII attached hereto (the
     "Non-U.S. Applications") (collectively, the U.S. Applications and the
     Non-U.S. Applications are referred to herein as the "Applications").  Such
     counsel knows of no


                                          23
<PAGE>

     claims of third parties to any of the Non-U.S. Patents or Non-U.S.
     Applications that would conflict with the Company's License Rights under
     the Amended and Restated License Agreement.

                    (iii)     Pursuant to the Amended and Restated License
     Agreement, ECC's License Rights apply with respect to all of the U.S.
     Patents, Non-U.S. Patents, U.S. Applications and Non-U.S. Applications
     listed in Schedules IV, V, VI and VII.  To the best of such counsel's
     knowledge, no other person or entity has obtained any rights from EKI that
     would diminish the exclusive rights the Company obtained under the Amended
     and Restated License Agreement.

                    (iv)      Such counsel has reviewed the statements under 
     the Registration Statement/Prospectuses captions "Risk 
     Factors--Protection of Proprietary Technology," "Business--The 
     Technology," and  "Business--Patents, Proprietary Rights and Trademarks" 
     (collectively, the "Intellectual Property Portion") of the Registration 
     Statement and the Prospectuses. Insofar as such statements constitute a 
     summary of EKI's Patents and Applications and the Company's License 
     Rights, and matters related thereto, such counsel believes them to 
     fairly, accurately and completely summarize the legal matters, documents 
     and proceedings relating to such Patents and Applications and license 
     rights described therein.  Nothing has come to the attention of such 
     counsel which causes it to believe that the information in the 
     Intellectual Property Portion contains any untrue statement of a 
     material fact or omits to state a material fact which is required to be 
     stated therein or necessary to make the statements therein not 
     misleading.

                    (v)       Such counsel has no knowledge of any facts that
     (i) would preclude the Company from having clear, exclusive rights to the
     patents and Applications as granted by the Amended and Restated License
     Agreement; (ii) would lead such counsel to conclude that any of the
     Patents are invalid or unenforceable; or (iii) that any patent that may
     ultimately issue from one or more of the Applications would be invalid or
     unenforceable.  Such counsel has no knowledge of any facts that cause it to
     believe that the Company lacks any rights to use all intellectual property
     necessary to conduct its business as now or proposed to be conducted or as
     described in the Registration Statement or the Prospectuses.  Such counsel
     has knowledge of no facts that would preclude the Company from using the
     Patents against third parties to prevent such third parties from engaging
     in infringing conduct.

                    (vi)      Such counsel has been advised by the Company of
     certain specifications for compositions and processes for use in making
     foamed starch based food containers and more specifically for a container
     for the McDonald's Quarter Pounder with Cheese and a container for the
     McDonald's Big Mac (such specifications are attached hereto as Schedule
     VIII).  Such counsel is not aware of any patent owned by a party other than
     EKI that would be infringed by making food containers using the Schedule
     VIII specifications. Such counsel has also been advised of pre-commercial
     specifications for compositions and processes for use in making cellulose
     ether based inorganically filled


                                          24
<PAGE>

     sheets which might be useable in making food and drink containers.  Such
     counsel is not aware of any patent owned by a party other than EKI that
     would be infringed by making food containers using specifications for
     compositions and processes for use in making cellulose ether based
     inorganically filled sheets.

                    (vii)     Such counsel is not aware of any material defect
     of form in the preparation or filing of the Applications on behalf of EKI.
     To such counsel's knowledge none of the Applications (excepting specific
     claims therein) has been finally rejected by the examining agency.

                    (viii)    To the best of such counsel's knowledge, the
     Company has complied with the United States Patent and Trademark Office
     duty of candor and disclosure during the prosecution leading to the
     issuance of each of the U.S. Patents.

                    (ix)      The Amended and Restated License Agreement has
     been duly authorized, executed and delivered and is a legal, valid and
     binding agreement, enforceable against EKI in accordance with its terms.

                    (x)       Such counsel knows of no pending or threatened
     action, suit, proceeding or claim by governmental authorities or others
     that the Company is infringing or otherwise violating any patents or trade
     secrets.

                    (xi)      Such counsel is not aware of any pending or
     threatened actions, suits, proceedings or claim by governmental authorities
     or others challenging the validity or scope of the Patents.

                    (xii)     Such counsel is not aware of any infringement on
     the part of any third party of any patent or trade secret in violation of
     rights held by the Company.

               (d)  The Company shall have furnished to the International
Representatives and the Selling Stockholders the opinion of Olsson, Frank &
Weeda, P.C., special regulatory counsel for the Company, dated the Closing Date,
to the effect that:

                    (i)       The statements under the captions "Risk
     Factors--FDA Regulation," and "Business--Government Regulation"
     (collectively, the "Regulatory Portion") in the Registration Statement and
     the Prospectuses and any amendment or supplement thereto, to the extent
     that they reflect matters of law, summaries of law or regulations, or
     regulatory status of the Company, are correct and complete in all material
     respects, subject to the qualifications set forth therein;

                    (ii)      Each of the components of the Company's Big Mac
     sandwich container ("Big Mac Container") is either approved by the Food and
     Drug Administration (the "FDA") as an indirect food additive for its
     intended use, is codified in the regulations of the FDA as "generally
     recognized as safe" ("GRAS"), or is regarded by the Company and its
     consultants (including such counsel) as GRAS for its intended


                                          25
<PAGE>

     use.  Sale of products manufactured using the formulation of Ali-ite used
     in manufacturing the prototype Big Mac Container does not violate the laws
     and regulations of the FDA.

                    (iii)     Nothing has come to the attention of such counsel
     which causes such counsel to believe that the information contained in
     (a) the Registration Statement, or any amendments thereof contained or
     contains an untrue statement of a material fact or omitted or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading, or (b) the Prospectuses, or any
     amendments thereof, contained or contains an untrue statement of a material
     fact or omitted or omits to state any material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading.

               (e)  The Company shall have furnished to the International 
Representatives and the Selling Stockholders the opinion of Paul, Hastings, 
Janofsky & Walker LLP, environmental counsel for the Company, dated the 
Closing Date, to the effect that nothing has come to the attention of such 
counsel which causes such counsel to believe that the information contained 
in (a) the Registration Statement, or any amendments thereof contained or 
contains an untrue statement of a material fact or omitted or omits to state 
a material fact required to be stated therein or necessary to make the 
statements therein not misleading, or (b) the Prospectuses, or any amendments 
thereof, contained or contains an untrue statement of a material fact or 
omitted or omits to state any material fact required to be stated therein or 
necessary to make the statements therein, in light of the circumstances under 
which they were made, not misleading.

               (f)  The Selling Stockholders shall have furnished to the
International Representatives the opinion of Milbank, Tweed, Hadley & McCloy,
counsel for the Selling Stockholders, dated the Closing Date, to the effect
that:

                    (i)       Each Selling Stockholder is the record owner of
     the Securities to be sold by such Selling Stockholder pursuant to this
     Agreement or the U.S. Underwriting Agreement; and

                    (ii)      Upon payment for and delivery of the Securities in
     accordance with the terms of this Agreement and the U.S. Underwriting
     Agreement, and assuming the Underwriters are acquiring the Securities
     purchased by them in good faith without notice of any adverse claim (as
     defined in Section 8102(a)(1) of the California Uniform Commercial Code),
     the Underwriters will be the owners of the Securities purchased by them,
     free and clear of any adverse claim.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the States of Delaware,
New York or California or the Federal laws of the United States, to the extent
they deem proper and specified in such opinion, upon the opinion of other
counsel of good standing whom they believe to be reliable and who are
satisfactory to counsel for the International Underwriters, and (B) as to
matters of fact, to the


                                          26
<PAGE>

extent they deem proper, on certificates of responsible officers of the 
Selling Stockholders and the Contributing Stockholders and public officials.

               (g)  The International Representatives shall have received from
Latham & Watkins, counsel for the International Underwriters, such opinion or
opinions, dated the Closing Date, with respect to the issuance and sale of the
International Securities, the Registration Statement, the Prospectuses (together
with any supplement thereto) and other related matters as the International
Representatives may reasonably require, and the Company and each Selling
Stockholder shall have furnished to such counsel such documents as they request
for the purpose of enabling them to pass upon such matters.


               (h)  The Company shall have furnished to the Representatives a
certificate of the Company, signed by the Chairman of the Board, the President
and the principal financial or accounting officer of the Company, dated the
Closing Date, to the effect that the signers of such certificate have carefully
examined the Registration Statement, the Prospectuses, any supplements to the
Prospectuses and this Agreement and that:

                    (i)       the representations and warranties of the Company
     in this Agreement are true and correct in all material respects on and as
     of the Closing Date with the same effect as if made on the Closing Date and
     the Company has complied with all the agreements and satisfied all the
     conditions on its part to be performed or satisfied at or prior to the
     Closing Date;

                    (ii)      no stop order suspending the effectiveness of the
     Registration Statement has been issued and no proceedings for that purpose
     have been instituted or, to the Company's knowledge, threatened; and

                    (iii)     since the date of the most recent financial
     statements included in the Prospectuses (exclusive of any supplement
     thereto), there has been no Material Adverse Effect.

               (i)  Each Selling Stockholder shall have furnished to the
Representatives a certificate, signed by the Chairman of the Board, the
President and the principal financial or accounting officer of such Selling
Stockholder or by or on behalf of such Selling Stockholder, individually, dated
the Closing Date, to the effect that the representations and warranties of such
Selling Stockholder in this Agreement and in the Custody Agreement and Power of
Attorney are true and correct in all material respects on and as of the Closing
Date to the same effect as if made on the Closing Date.

               (j)  At the Execution Time and at the Closing Date, Deloitte & 
Touche LLP shall have furnished to the International Representatives and the 
Selling Stockholders letters, dated respectively as of the Execution Time and 
as of the Closing Date, in form and substance satisfactory to the 
International Representatives, confirming that they are independent 
accountants within the meaning of the Act and the applicable published rules 
and regulations thereunder and that they have performed a review of the 
financial information of the Company contained in the

                                          27
<PAGE>

Registration Statement and Prospectuses, in accordance with Statement on
Accounting Standards No. 71 and stating in effect that:

                    (i)       in their opinion the audited financial statements
     and financial statement schedules and pro forma financial statements
     included in the Registration Statement and the Prospectuses and reported on
     by them comply in form in all material respects with the applicable
     accounting requirements of the Act and the related published rules and
     regulations;

                    (ii)      on the basis of a reading of the latest unaudited
     financial statements made available by the Company; their limited review,
     in accordance with standards established under Statement on Auditing
     Standards No. 71 of the unaudited interim financial information, if any,
     carrying out certain specified procedures (but not an examination in
     accordance with generally accepted auditing standards) which would not
     necessarily reveal matters of significance with respect to the comments set
     forth in such letter; a reading of the minutes of the meetings of the
     stockholders, directors and the Executive, Compensation, Audit, Conflicts
     and Stock Option committees of the Company; and inquiries of certain
     officials of the Company who have responsibility for financial and
     accounting matters of the Company as to transactions and events subsequent
     to December 31, 1997, nothing came to their attention which caused them to
     believe that:

                              (1)  any unaudited financial statements, if any,
          included in the Registration Statement and the Prospectuses do not
          comply in form in all material respects with applicable accounting
          requirements of the Act and with the published rules and regulations
          of the Commission with respect to registration statements on Form S-1;
          and said unaudited financial statements are not in conformity with
          generally accepted accounting principles applied on a basis
          substantially consistent with that of the audited financial statements
          included in the Registration Statement and the Prospectuses;

                              (2)  with respect to the period subsequent to
          December 31, 1997, there were any changes in the long-term debt of the
          Company or capital stock of the Company or decreases in the
          stockholders' equity of the Company as compared with the amounts shown
          on the December 31, 1997 consolidated balance sheet included in the
          Registration Statement and the Prospectuses, or for the period
          subsequent to December 31, 1997 there were any decreases, as compared
          with the corresponding period in the preceding year in net revenues or
          income before income taxes or in total or per share amounts of net
          income of the Company, except in all instances for changes or
          decreases set forth in such letter, in which case the letter shall be
          accompanied by an explanation by the Company as to the significance
          thereof unless said explanation is not deemed necessary by the
          International Representatives; or


                                          28
<PAGE>

                              (3)  the information included in the Registration
          Statement and Prospectuses in response to Regulation S-K, Item 301
          (Selected Financial Data), Item 302 (Supplementary Financial
          Information), Item 402 (Executive Compensation) and Item 503(d) (Ratio
          of Earnings to Fixed Charges) is not in conformity with the applicable
          disclosure requirements of Regulation S-K.

                    (iii)     they have performed certain other specified
     procedures as a result of which they determined that certain information of
     an accounting, financial or statistical nature (which is limited to
     accounting, financial or statistical information derived from the general
     accounting records of the Company and its subsidiaries) set forth in the
     Registration Statement and the Prospectuses, including the information set
     forth under the captions "Selected Financial Data" and "Experts" in the
     Prospectuses, agrees with the accounting records of the Company and its
     subsidiaries, excluding any questions of legal interpretation.

                    (iv)      on the basis of a reading of the unaudited pro
     forma financial statements included in the Registration Statement and the
     Prospectuses (the "pro forma financial statements"); carrying out certain
     specified procedures; inquiries of certain officials of the Company who
     have responsibility for financial and accounting matters; and proving the
     arithmetic accuracy of the application of the pro forma adjustments to the
     historical amounts in the pro forma financial statements, nothing came to
     their attention which caused them to believe that the pro forma financial
     statements do not comply in form in all material respects with the
     applicable accounting requirements of Rule 11-02 of Regulation S-X or that
     the pro forma adjustments have not been properly applied to the historical
     amounts in the compilation of such statements.

                    References to the Prospectuses in this paragraph (j) include
     any supplement thereto at the date of the letter.

               (k)  Subsequent to the Execution Time or, if earlier, the dates
as of which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectuses (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letter or
letters referred to in paragraph (j) of this Section 6 or (ii) any change, or
any development involving a prospective change, in or affecting the condition
(financial or otherwise), earnings, business or properties of the Company, taken
as a whole, whether or not arising from transactions in the ordinary course of
business, except as set forth in or contemplated in the Prospectuses (exclusive
of any supplement thereto) the effect of which, in any case referred to in
clause (i) or (ii) above, is, in the sole judgment of the International
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectuses (exclusive of any supplement thereto).


                                          29

               (l)  On or prior to the Execution Time, the National Association
of Securities Dealers shall have approved the Underwriters' participation in the
distribution of the Securities to be sold by the Selling Stockholders.

               (m)  At the Execution Time, unless otherwise agreed to in writing
by the Representatives, the Company shall have furnished to the Representatives
a letter substantially in the form of Exhibit A hereto from each officer and
director of the Company and stockholders addressed to the Representatives, in
which each such person agreed that, until such date which is (a) 270 days after
the Closing Date if such person is a Selling Stockholder or (b) 180 days after
the Closing Date if such person is not a Selling Stockholder, without the prior
written consent of Salomon Brothers Inc, such person will not, directly or
indirectly, offer, sell, contract to sell, grant any option or warrant for the
sale of, register, loan, pledge, grant any rights with respect to, or otherwise
transfer or dispose of any shares of capital stock of the Company or securities
convertible into or exchangeable or exercisable for, or any rights to purchase
or acquire, such shares of capital stock, including, without limitation, Common
Stock which now or hereafter may be deemed to be beneficially owned by such
person, subject to certain exceptions set forth therein.  It is understood that
as joint book-running managers Salomon Brothers Inc and Smith Barney Inc., on
the one hand, and Credit Suisse First Boston Corporation, on the other hand,
have agreed not to release the Company or any stockholders of the Company from
any restriction on transactions relating to the Company's securities without the
written consent of the other.

               (n)  On or prior to the Execution Time, the Nasdaq National
Market shall have approved the quotation of the Securities on the Nasdaq
National Market.

               (o)  Prior to the Closing Date, the Company shall have furnished
to the International Representatives such further information, certificates and
documents as the International Representatives may reasonably request.

               (p)  The closing of the purchase of the U.S. Underwritten
Securities to be issued and sold by the Company pursuant to the U.S.
Underwriting Agreement shall occur concurrently with the closing described
herein.

               (q)  The Company shall have caused the conversion for all Selling
Stockholders of the shares of Series A Cumulative Senior Convertible Preferred
Stock of the Company into shares of Common Stock.

               (r)  The Company shall have caused the recapitalization and stock
split to become effective in which each share of Common Stock will be converted
into 262 shares of Common Stock.

               (s)  The Company shall have caused the Company's Certificate of
Incorporation and by-laws to be amended to, among other things, change the
Company's name to EarthShell Corporation from EarthShell Container Corporation.


                                          30

               (t)  The Company shall have arranged for proceeds from the sale
of Common Stock contemplated hereunder to be paid to Imperial Bank in
satisfaction of all amounts owing under the Company's Credit Facility and for
termination of such Credit Facility in connection therewith.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancellation shall be given to the Company and each Selling Stockholder in
writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be
delivered at the office of Latham & Watkins, counsel for the International
Underwriters, at 650 Town Center Drive, 20th Floor, Costa Mesa, California
92626, on the Closing Date.

          7.   REIMBURSEMENT OF INTERNATIONAL UNDERWRITERS' EXPENSES.  If the
sale of the Securities provided for herein is not consummated because any
condition to the obligations of the International Underwriters set forth in
Section 6 hereof is not satisfied, because of any termination pursuant to
Section 10 hereof or because of any refusal, inability or failure on the part of
the Company or any Selling Stockholder to perform any agreement herein or comply
with any provision hereof other than by reason of a default by any of the
International Underwriters, the Company will reimburse the International
Underwriters severally through Smith Barney Inc. on demand for all out-of-pocket
expenses (including reasonable fees and disbursements of counsel) that shall
have been incurred by them in connection with the proposed purchase and sale of
the International Securities.  If the Company is required to make any payments
to the International Underwriters under this Section 7 because of any Selling
Stockholder's refusal, inability or failure to satisfy any condition to the
obligations of the International Underwriters set forth in Section 6, such
Selling Stockholders shall, together with any other Selling Stockholders so
refusing, unable or failing to satisfy such conditions, on a pro rata basis,
reimburse the Company on demand for all amounts so paid.

          8.   INDEMNIFICATION AND CONTRIBUTION.

               (a)  The Company and EKI jointly and severally agree to indemnify
and hold harmless each Underwriter, the directors, officers, employees and
agents of each Underwriter and each person who controls any Underwriter within
the meaning of either the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the registration statement for


                                          31
<PAGE>

the registration of the Securities as originally filed or in any amendment
thereof, or in any U.S. or International Preliminary Prospectus or in either of
the Prospectuses, or in any amendment thereof or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; PROVIDED, HOWEVER, that the Company and EKI will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made therein in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of any International Underwriter through the International
Representatives specifically for inclusion therein.  This indemnity agreement
will be in addition to any liability which the Company and EKI may otherwise
have.

               (b)  Each Selling Stockholder severally agrees to indemnify and
hold harmless the Company, each of its directors, each of its officers who signs
the Registration Statement, each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls the Company or any
Underwriter within the meaning of either the Act or the Exchange Act, each other
Selling Stockholder to the same extent as the foregoing indemnity from the
Company and EKI to each Underwriter, but only with reference to written
information furnished to the Company by or on behalf of such Selling Stockholder
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Selling Stockholder may otherwise have.  Notwithstanding anything to the
contrary in this Agreement, the aggregate liability any Selling Stockholder
shall have to all International Underwriters and other persons and entities
pursuant to this Agreement (whether pursuant to Section 1(b), 8(b), 8(e) or
otherwise), shall not exceed an amount equal to the net proceeds (after
deducting the Underwriters' discount) received by such Selling Stockholder from
the sale of the Securities pursuant to this Agreement.

               (c)  Each International Underwriter severally agrees to indemnify
and hold harmless the Company, each of its directors, each of its officers who
signs the Registration Statement, and each person who controls the Company
within the meaning of either the Act or the Exchange Act and each Selling
Stockholder and, to the same extent as the foregoing indemnity to each
International Underwriter, but only with reference to written information
relating to such International Underwriter furnished to the Company by or on
behalf of such International Underwriter through the International
Representatives specifically for inclusion in the documents referred to in the
foregoing indemnity.  This indemnity agreement will be in addition to any
liability which any International Underwriter may otherwise have.  The Company
and each Selling Stockholder acknowledge that the statements set forth in the
last paragraph of the cover page regarding delivery of the International
Securities, the stabilization legend in block capital letters on page 2 and,
under the heading "Subscription and Sale," (i) the sentences related to
concessions and reallowances and (ii) the paragraph related to stabilization in
the Prospectuses constitute the only information furnished in writing by or on
behalf of the several International Underwriters for inclusion in the
Prospectuses.


                                          32
<PAGE>

               (d)  Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party
(i) will not relieve it from liability under paragraph (a), (b) or (c) above
unless and to the extent it did not otherwise learn of such action and such
failure results in the forfeiture by the indemnifying party of substantial
rights and defenses and (ii) will not, in any event, relieve the indemnifying
party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a), (b) or (c) above.  The
indemnifying party shall be entitled to appoint counsel of the indemnifying
party's choice at the indemnifying party's expense to represent the indemnified
party in any action for which indemnification is sought (in which case the
indemnifying party shall not thereafter be responsible for the fees and expenses
of any separate counsel retained by the indemnified party or parties except as
set forth below); PROVIDED, HOWEVER, that such counsel shall be satisfactory to
the indemnified party.  Notwithstanding the indemnifying party's election to
appoint counsel to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party.  An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

               (e)  In the event that the indemnity provided in paragraph (a),
(b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless
an indemnified party for any reason, the Company, the Selling Stockholders and
the International Underwriters agree to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) (collectively
"Losses") to which the Company, one or more of the Selling Stockholders and one
or more of the International Underwriters may be subject in such proportion as
is appropriate to reflect the relative benefits received by the Company, by the
Selling Stockholders and by the International Underwriters from the offering of
the International Securities; PROVIDED, HOWEVER, that in no case shall any
International Underwriter (except as may be provided in any agreement among
underwriters relating to the offering of the International Securities) be
responsible for any amount


                                          33

in excess of the underwriting discount or commission applicable to the
Securities purchased by such International Underwriter hereunder.  If the
allocation provided by the immediately preceding sentence is unavailable for any
reason, the Company, the Selling Stockholders and the International Underwriters
shall contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company, of the Selling
Stockholders, and of the International Underwriters in connection with the
statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations.  Benefits received by the Company and by the
Selling Stockholders shall be deemed to be equal to the total net proceeds from
the offering (before deducting expenses) received by each of them, and benefits
received by the International Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the International Prospectus.  Relative fault shall be determined
by reference to, among other things, whether any untrue or any alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information provided by the Company, the Selling
Stockholders or the International Underwriters, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission.  The Company, the Selling
Stockholders and the International Underwriters agree that it would not be just
and equitable if contribution were determined by pro rata allocation or any
other method of allocation which does not take account of the equitable
considerations referred to above.  Notwithstanding the provisions of this
paragraph (e), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.  For purposes of
this Section 8, each person who controls an International Underwriter within the
meaning of either the Act or the Exchange Act and each director, officer,
employee and agent of an International Underwriter shall have the same rights to
contribution as such International Underwriter, and each person who controls the
Company within the meaning of either the Act or the Exchange Act, each officer
of the Company who shall have signed the Registration Statement and each
director of the Company shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
paragraph (e).

          9.   DEFAULT BY AN INTERNATIONAL UNDERWRITER.  If any one or more
International Underwriters shall fail to purchase and pay for any of the
International Securities agreed to be purchased by such International
Underwriter or International Underwriters hereunder and such failure to purchase
shall constitute a default in the performance of its or their obligations under
this Agreement, the remaining International Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the amount
of International Securities set forth opposite their names in Schedule I hereto
bears to the aggregate amount of International Securities set forth opposite the
names of all the remaining International Underwriters) the International
Securities which the defaulting International Underwriter or International
Underwriters agreed but failed to purchase; PROVIDED, HOWEVER, that in the event
that the aggregate amount of International Securities which the defaulting
International Underwriter or International Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of International Securities
set forth in Schedule I hereto, the remaining International Underwriters shall
have the right to purchase all, but shall not be under any obligation to


                                          34
<PAGE>

purchase any, of the International Securities, and if such nondefaulting
International Underwriters do not purchase all the International Securities,
this Agreement will terminate without liability to any nondefaulting
International Underwriter, the Selling Stockholders or the Company.  In the
event of a default by any International Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the International Representatives shall determine in
order that the required changes in the Registration Statement and the
Prospectuses or in any other documents or arrangements may be effected.  Nothing
contained in this Agreement shall relieve any defaulting International
Underwriter of its liability, if any, to the Company, the Selling Stockholders
and any nondefaulting International Underwriter for damages occasioned by its
default hereunder.

          10.  TERMINATION.  This Agreement shall be subject to termination in
the absolute discretion of the International Representatives, by written notice
given to the Company prior to delivery of and payment for the International
Securities, if at any time prior to such time (i) a banking moratorium shall
have been declared either by Federal or New York State authorities, (ii) trading
in securities on the New York Stock Exchange or the Nasdaq National Market shall
have been suspended or limited or minimum prices shall have been established on
such Exchange or National Market, or (iii) there shall have occurred any
outbreak or escalation of hostilities, declaration by the United States of a
national emergency or war or other calamity or crisis the effect of which on
financial markets is such as to make it, in the sole judgment of the
International Representatives, impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the International
Prospectus (exclusive of any supplement thereto).

          11.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE.  The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers, of each of the Selling Stockholders and of the
International Underwriters set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of any International Underwriter, any Selling Stockholder or the Company
or any of the officers, directors or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the International
Securities.  The provisions of Sections 7 and 8 hereof shall survive the
termination or cancellation of this Agreement.

          12.  NOTICES.  All communications hereunder will be in writing and 
effective only on receipt, and, if sent to the International Representatives,

                                 LOCK-UP AGREEMENT
January __, 1998

Salomon Brothers Inc.
Credit Suisse First Boston
     As Representatives of the Several Underwriters,
     c/o  Salomon Brothers Inc
          Seven World Trade Center
          New York, New York 10048

Ladies and Gentlemen:

          Reference is made to the proposed initial public offering (the
"Offering") of the Common Stock, $.01 par value per share (the "Common Stock"),
of EarthShell Corporation, a Delaware corporation (the "Company"), pursuant to
which Salomon Brothers Inc and Credit Suisse First Boston, together with certain
of their affiliated international entities, will serve as representatives (the
"Representatives") of the various underwriters (the "Underwriters").

          The undersigned understands that the Underwriters propose to enter
into a U.S. Underwriting Agreement and an International Underwriting Agreement
(the "Underwriting Agreements") with the Company providing for the purchase by
the Underwriters of the Common Stock and that the Underwriters propose to
reoffer the Common Stock in a public offering.

          In consideration of the execution of the Underwriting Agreements by
the Representatives, the undersigned agrees that, until such date which is (a)
270 days after the consummation (the "Closing Date") of the Offering if the
undersigned is selling Common Stock in the Offering (including shares, if any,
sold as part of the over-allotment option granted to the Underwriters) or (b)
180 days after the Closing Date of the Offering if the undersigned is not
selling Common Stock in the Offering (including shares, if any, sold as part of
the over-allotment option granted to the Underwriters) (such 270-day or 180-day
period is hereafter referred to as the "Lock-up Period"), without the prior
written consent of Salomon Brothers Inc, the undersigned will not, directly or
indirectly, offer, sell, contract to sell, grant any option or warrant for the
sale of, register, loan, pledge, grant any rights with respect to, or otherwise
transfer or dispose of (collectively, a "Disposition") any shares of capital
stock of the Company or securities convertible into or exchangeable or
exercisable for, or any rights to purchase or acquire, such shares of capital
stock, including, without limitation, Common Stock which now or hereafter may be
deemed to be beneficially owned by the undersigned (collectively, the
"Securities") (beneficial ownership to be determined in accordance with the
rules and regulations of the


                                         A-1
<PAGE>

Securities and Exchange Commission); provided, however, that the undersigned may
transfer shares of (i) capital stock to one or more affiliates (including
partners of any partnership) or one or more members of the undersigned's
immediate family, or a trust, the sole beneficiaries of which are members of
such individual's immediate family, provided, that the transferee agrees in
writing to be bound by the terms of this letter agreement, (ii) Series A
Cumulative Senior Convertible Preferred Stock (the "Preferred Stock") to the
Company pursuant to the redemption provisions of the Certificate of Designation
of the Preferred Stock (the "Certificate of Designation"), (iii) Preferred Stock
to the Company in exchange for Common Stock pursuant to the conversion
provisions of the Certificate of Designation and (iv) Common Stock to the
Underwriters in the Offering, including pursuant to the over-allotment option
granted to the Underwriters.

          The foregoing restriction is expressly agreed to preclude the
undersigned from engaging in any hedging or other transaction which is designed
to or reasonably expected to lead to or result in a Disposition of Securities
during the Lock-up Period, even if such Securities would be disposed of by
someone other than the undersigned.  Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or any purchase, sale or grant of any right (including, without
limitation, any put or call option) with respect to any Securities or with
respect to any security (other than a broad-based market basket or index) that
includes, relate to or derives any significant part of its value from
Securities.

          The undersigned agrees and consents to the entry of stop transfer
instructions with the transfer agent for the Company's capital stock against any
transfer of shares of capital stock of the Company in contravention of the
restrictions set forth above.  The undersigned confirms that it understands that
the Underwriters and the Company will rely upon the representations set forth in
this letter in proceeding with the Offering.

          The undersigned hereby represents and warrants that the undersigned
has full power and authority to enter into this letter agreement, and that, upon
request, the undersigned will execute any additional documents necessary or
desirable in connection with the enforcement hereof.

          All authority herein conferred or agreed to be conferred shall survive
the death of incapacity of the undersigned and any obligations of the
undersigned shall be binding upon the heirs, personal representatives,
successors and assigns of the undersigned.

          If, for any reason, the Closing Date of the Offering does not occur
prior to May 31, 1998, or if the Underwriting Agreement shall be terminated
prior to the Closing Date (as defined in the Underwriting Agreement), this
agreement shall be terminated.
