BASIS OF PRESENTATION The accompanying, unaudited, condensed consolidated financial statements have been prepared by the Company in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying financial statements include all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. Results of operations for the three and nine months ended September 30, 1996 are not necessarily indicative of the results that may be expected for the entire fiscal year ended December 31, 1996. For further information, refer to the audited financial statements and footnotes thereto as of December 31, 1995 included in the Company's Annual Report to Stockholders and the Annual Report on Form 10-K filed with the Securities and Exchange Commission. NOTE 2. PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of the Company and Modex Therapeutiques SA, a 50% owned subsidiary. Significant intercompany accounts have been eliminated in consolidation. NOTE 3. NET LOSS PER SHARE Net loss per share is computed using the weighted average number of shares of common stock outstanding. Common equivalent shares from stock options and warrants are excluded as their effect is antidilutive. NOTE 4. FOREIGN CURRENCY TRANSLATION Assets and liabilities of operations outside the United States are translated into United States dollars using current exchange rates; revenue and expense items are translated into United States dollars using a weighted average exchange rate for the period. The gains and losses resulting from such translation are accumulated as a separate component of shareholders' equity, whereas gains and losses resulting from foreign currency transactions generally are included in results of operations. 7 NOTE 5. ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS The Company has adopted Statement of Financial Accounting Standards No. 121 ("SFAS 121"), Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, which requires impairment losses to be recorded on the long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amount. SFAS 121 also addresses the accounting for long-lived assets that are expected to be disposed of. The adoption of SFAS 121 had no impact on the financial position or results of operations of the Company as no indicators of impairment currently exist. The Company has adopted the disclosure provisions of Financial Accounting Standards No. 123 ("SFAS 123"), Accounting and Disclosure of Stock-Based Compensation. The Company will continue to account for its stock-based compensation arrangements under the provisions of APB 25, Accounting for Stock Issued to Employees. NOTE 6. FORMATION OF SUBSIDIARY On July 10, 1996, The Company participated in the establishment of Modex Therapeutiques SA, "Modex", as a 50% owned subsidiary to pursue extensions of the Company's encapsulated-cell technology for applications outside the central nervous system. Modex is headquartered in Lausanne, Switerland. In exchange for a 50% stake in Modex, the Company has invested $2 million in Modex, with a commitment to invest an additional $2 million on the second anniversary of the agreement if Modex has, prior to that time, achieved one of more specified scientific milestones. An investment fund, managed by a Swiss private bank, has invested $2 million in Modex, with a commitment to invest an additional $1 million on the second anniversary of the agreement, in exchange for a 15% stake in the company. The remaining 35% of Modex is owned by the scientific founders of Modex. The Company has granted to Modex an exclusive, royalty-bearing license to the Company's proprietary encapsulated-cell technology for three applications outside the central nervous system; diabetes, obesity and anemia. Modex granted the Company an exclusive royalty-bearing license to any technology developed or obtained by Modex for application to diseases, conditions and disorders which affect the central nervous system. In addition to its royalty obligations, the Company is also obligated to issue to Modex up to 300,000 shares of the Company's Common Stock on the achievement by Modex of certain scientific milestones. Substantially all of these shares are expected to be awarded by Modex as incentive compensation of Modex' founding scientists and other researchers upon the achievement of such milestones. Under the terms of its agreement with the investment fund, during the first two years following closing, the Company has the right to acquire the fund's interest in Modex for the greater of a 30% annual return or $3 million. Following this two year period, the Company has the right to purchase the fund's interest at 110% of fair market value. 8 Following the second anniversary of the agreement and prior to the tenth anniversary of the agreement, if no public market exists for the Common Stock of Modex, the fund has the right to require the Company to purchase the fund's interest in Modex for 90% of the fair market value of such interest. Any purchase made by the Company under any of the circumstances described in this paragraph may be made at the Company's option in cash or shares of the Company's Common Stock valued at the market price at the time of purchase. The Company also has the right to acquire, and the founders have the right to require the Company to acquire, the founders' initial equity interest in Modex in exchange for the issuance of an aggregate of approximately 92,000 shares of the Company's Common Stock. 9 PART I - ITEM 2 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion of the financial condition and results of operations of the Company for the three and nine months ended September 30, 1996 and 1995 should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and the related footnotes thereto. This report may contain certain forward-looking statements regarding, among other things, the Company's results of operations, the progress of the Company's product development programs, the Company's need for, and required timing of, additional capital, capital expenditures and need for additional facilities. The Company's actual results may vary materially from those contained in such forward-looking statements. See "Cautionary Factors Relevant to Forward-Looking-Information" filed herewith as Exhibit 99 and incorporated herein by reference. OVERVIEW Since its inception in 1988, the Company has been primarily engaged in research and development of human therapeutic products. No revenues have been derived from the sale of any products, and the Company does not expect to receive revenues from product sales for at least several years. The Company expects that its research and development expenditures will increase substantially in future years as research and product development efforts accelerate and clinical trials are broadened or initiated. The Company has incurred annual operating losses since inception and expects to incur substantial operating losses in the future. As a result, the Company is dependent upon external financing from equity and debt offerings and revenues from collaborative research arrangements with corporate sponsors to finance its operations. The Company's results of operations have varied significantly from period to period and may vary significantly in the future due to the occurrence of material, nonrecurring events, including without limitation, the receipt of one-time, nonrecurring licensing payments. Results may vary from quarter to quarter and results of one quarter may not be representative of the actual results for the year. RESULTS OF OPERATIONS THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995 For the quarter ended September 30, 1996 and 1995, revenues from collaborative agreements totaled $1,791,000 and $1,986,000, respectively. The revenues were earned solely from a Development, Marketing and License Agreement with Astra AB, which was signed in March 1995. 10 Research and development expenses totaled $4,205,000 for the three months ended September 30, 1996, compared with $3,730,000 for the same period in 1995. The increase of $475,000, or 13%, from 1995 to 1996 is principally due to increases in the number of scientists and increased spending for company sponsored research at academic and other institutions. General and administrative expenses were $1,611,000 for the three months ended September 30, 1996, compared with $1,035,000 for the same period in 1995. The increase of $576,000, or 56%, from 1995 to 1996 was primarily attributable to increases in spending for administrative salaries, one time hiring bonuses, as well as, consulting costs attributable to the establishment of Modex Therapeutiques SA, a 50% owned Swiss subsidiary. Interest income for the three months ended September 30, 1996 and 1995 was $526,000 and $407,000, respectively. The increase in interest income in 1996 is attributable to the higher average balances, $37,463,000 and $26,810,000 in the third quarter of 1996 and 1995, respectively. Interest expense was $163,000 for the three months ended September 30, 1996, compared with $151,000 for the same period in 1995. The increase from 1996 to 1995 was attributable to additional collateralized loan obligations recorded in connection with equipment financings offset, in part, by decreasing balances of existing capitalized leases obligations. Net loss for the three months ended September 30, 1996 was $3,608,000, or $0.23 per share, as compared to net loss of $2,523,000, or $0.19 per share, for the comparable period in 1995. RESULTS OF OPERATIONS NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995 For the nine months ended September 30, 1996 and 1995, revenues from collaborative agreements totaled $5,306,000 and $9,845,000, respectively. The revenues were earned solely from a Development, Marketing and License Agreement with Astra AB, which was signed in March 1995. Included in the 1995 revenues was a non-refundable, one-time payment from Astra totaling $5,000,000. Research and development expenses totaled $12,286,000 for the nine months ended September 30, 1996, compared with $10,734,000 for the same period in 1995. The increase of $1,552,000, or 14%, from 1995 to 1996 is principally due to increases in the number of scientists and associated supplies, increased spending for company sponsored research at academic and other institutions, scientific consulting and clinical trials. General and administrative expenses were $4,018,000 for the nine months ended September 30, 1996, compared with $3,252,000 for the same period in 1995. The 11 increase of $766,000, or 24%, from 1995 to 1996 was primarily attributable to increases in patent related expenses, spending for administrative salaries, one time hiring bonuses, as well as, consulting costs attributable to the establishment of Modex Therapeutiques SA, a 50% owned Swiss subsidiary. Other income in the amount of $397,000 consists primarily of funds received in May 1996 for settlement of a legal suit filed on behalf of the Company. Interest income for the nine months ended September 30, 1996 and 1995 was $1,733,000 and $1,051,000, respectively. The increase in interest income in 1996 is primarily attributable to the higher average balances, $39,505,000 and $21,701,000 for the first nine months of 1996 and 1995, respectively. Interest expense was $467,000 for the nine months ended September 30, 1996, compared with $440,000 for the same period in 1995. The increase from 1995 to 1996 was attributable to additional collateralized loan obligations recorded in connection with equipment financings offset, in part, by decreasing balances of existing capitalized leases obligations. Net loss for the nine months ended September 30, 1996 was $9,336,000 or $0.61 per share, as compared to net loss of $3,531,000, or $0.29 per share, for the comparable period in 1995. The initial one-time payment of $5,000,000 from Astra is principally responsible for the Company's decreased loss in the first six months of 1995. LIQUIDITY AND CAPITAL RESOURCES Since its inception, the Company has financed its operations through the sale of common and preferred stock, the issuance of long-term debt and capitalized lease obligations, revenues from collaborative agreements, research grants and interest income. The Company has unrestricted cash, cash equivalents, and marketable securities totaling $35,617,000 at September 30, 1996. Cash equivalents and marketable securities are invested in agencies of the U.S. government, investment grade corporate notes, time deposits and money market funds. In May 1996, the Company secured an equipment loan facility with a bank in the amount of $2,000,000. The Company has borrowed $741,000 under this agreement as of September 30, 1996. The loan requires interest payments only for the first year, principal payments are payable over a three-year period beginning May 1997. Any unused commitment expires on May 15, 1997. The loan is secured by equipment purchased with the proceeds of the credit facility. The Company currently occupies all of its laboratory and administrative office space, other than that at its pilot manufacturing site, under the terms of operating leases subject to termination upon nine months notice by the Company. As a result 12 of an anticipated increase in the number of employees, the Company's current facilities will not be sufficient to accommodate the Company's needs past the first half of 1997. The Company has purchased land and a building and will begin construction of a new headquarters and laboratory facility in the fourth quarter. The total cost of the project is estimated to be $7,600,000. In October 1996, the Company obtained financing of $5,500,000 from a bank, secured by a mortgage on the new facility. No funds have been borrowed under this agreement as of September 30, 1996. Any unused commitment expires October 31, 1997. Quarterly principal payments of 1/40 of the loan obligation commence September 30, 1997 with the balance due at maturity, October 2001. The loan agreement requires the Company provide cash collateral in the amount of 25% of the obligation if the Company's unencumbered cash balance falls below $25,000,000, 50% cash collateral if the Company's unencumbered cash balance falls below $20,000,000 and full cash collateral if the Company's unencumbered cash balance falls below $15,000,000. In July 1996, the Company invested $2 million in Modex, a 50% owned Swiss subsidiary, to pursue extensions of the Company's encapsulated-cell technology for applications outside the central nervous system, with a commitment to invest an additional $2 million on the second anniversary of the agreement if Modex has, prior to that time, achieved one or more specified scientific milestones. An investment fund, managed by a Swiss private bank, has invested $2 million in Modex, with a commitment to invest an additional $1 million on the second anniversary of the agreement, in exchange for a 15% stake in the company. The remaining 35% of Modex is owned by the scientific founders of Modex. The Company has granted to Modex an exclusive, royalty-bearing license to the Company's proprietary encapsulated-cell technology for three applications outside the central nervous system: diabetes, obesity and anemia. Modex granted the Company an exclusive royalty-bearing license to any technology developed or obtained by Modex for application to diseases, conditions and disorders which affect the central nervous system. In addition to its royalty obligations, the Company is also obligated to issue to Modex up to 300,000 shares of the Company's Common Stock on the achievement by Modex of certain scientific milestones. Substantially all of these shares are expected to be awarded by Modex as incentive compensation to Modex' founding scientists and other researchers upon achievement of such milestones. Under the terms of its agreement with the investment fund, during the first two years following closing, the Company has the right to acquire the fund's interest in Modex for the greater of a 30% annual return or $3 million. Following this two year period, the Company has the right to purchase the fund's interest at 110% of fair market value. Following the second anniversary of the agreement and prior to the tenth anniversary of the agreement, if no public market exists for the common stock of Modex, the fund has the right to require the Company to purchase the fund's interest in Modex for 90% of the 13 fair market value of such interest. Any purchase made by the Company under any of the circumstances described in this paragraph may be made at the Company's option in cash or shares of the Company's Common Stock valued at the market price at the time of purchase. The Company also has the right to acquire, and the founders have the right to require the Company to acquire, the founders' initial equity interest in Modex in exchange for the issuance of an aggregate of approximately 92,000 shares of the Company's Common Stock. In March 1995, the Company signed a collaborative research and development agreement with Astra for the development and marketing of certain encapsulated-cell products to treat pain. Astra made an initial, nonrefundable payment of $5,000,000 and may make up to $16,000,000 in additional payments subject to the achievement of certain development milestones. Under the agreement, the Company is obligated to conduct certain research and development pursuant to a four-year research plan agreed upon by the parties. Over the term of the agreement, the Company expects to receive annual research payments from Astra of $5 million to $7 million, which the Company expects should approximate the research and development costs incurred by the Company under the plan. Subject to the successful development of such products and obtaining necessary regulatory approvals, Astra is obligated to conduct all clinical trials of products arising from the collaboration and to seek approval for their sale and use. Astra has the exclusive worldwide right to market products covered by the agreement. Until the later of either the last to expire of all patents included in the licensed technology or a specified fixed term, the Company is entitled to a royalty on the worldwide net sales of such products in return for the license granted to Astra and the Company's obligation to manufacture and supply products. Astra has the right to terminate the agreement after April 1, 1998. In March 1994, the Company entered into a Development Collaboration and License Agreement with Genentech, Inc. relating to the development of products for the encapsulation of certain neurotrophic factors. The initial focus of the collaboration has been the development of encapsulated NGF-producing cells for the treatment of Alzheimer's disease. In addition to NGF, the agreement also covers the neurotrophic factors NT-3, NT-4/5 and two other neurotrophic factors to be chosen by Genentech. The agreement provides that Genentech and the Company will work exclusively with each other to develop and commercialize NGF-producing encapsulated-cell products; that Genentech will not work with any third party in the field of the treatment of neurological disease by the administration of encapsulated neurotrophic factor-producing mammalian cells, without the Company's consent; and that the Company will not work with the neurotrophic factors NGF, NT-3 and NT-4/5 with any third party, without Genentech's consent. Under the Agreement, the Company granted to Genentech an exclusive license to use any of the company's existing and future technology to sell NGF-producing encapsulated-cell products in the field of the treatment of any human neurological disorder or condition by the administration of neurotrophic-factor producing encapsulated cells. Upon execution of the Agreement, Genentech made a 14 $1,250,000 payment to CytoTherapeutics, and purchased 334,428 shares of the Company's Common Stock for $3,500,000. Under the Agreement, the Company was obligated to undertake certain preclinical development projects and studies and to fund the $3,750,000 cost of such projects and 40% of such cost thereafter. The Company and Genentech have decided that Alzheimer's disease is not the most appropriate disease state to emphasize at this time under their collaboration agreement and are discussing other applications of the technologies. The Company has expended approximately $1,500,000 to fund the preclinical development projects and studies contemplated under the Agreement and does not currently expect to incur any further material expenditures for such projects and studies. The Company expects that future collaborations, if any, will involve new commitments and funding mechanisms. In March 1994, the Company entered into a contract research and license agreement with NeuroSpheres, Ltd. Under the agreement, the Company obtained from NeuroSpheres an exclusive worldwide royalty-bearing license for the commercial development and use of certain neural stem cells for transplantation to treat human disease. Terms of the agreement provide future research funding of $250,000 through February 1998. Upon the achievement of certain milestones, the Company will make payments to NeuroSpheres totaling a maximum of $3,750,000, payable at NeuroSpheres' option, in cash or in shares of the Company's common stock at a price of $12.50 per share. Upon commercial sale of a product utilizing the licensed technology, the Company is obligated to pay a range of royalties based on product revenues and market share, subject to certain minimum royalties. In order to maintain exclusivity, the Company is also obligated to expend additional amounts to support research related to development of products under the agreement. Substantial additional funds will be required to support the Company's research and development programs, for acquisition of technologies and intellectual property rights, for preclinical and clinical testing of its anticipated products, pursuit of regulatory approvals, acquisition of capital equipment, expansion of laboratory and office facilities, establishment of production capabilities and for general and administrative expenses. Until the Company's operations generate significant revenues from product sales, cash reserves and proceeds from equity and debt offering, and funding from collaborative arrangements will be used to fund operations. The Company intends to pursue opportunities to obtain additional financing in the future through equity and debt financings, lease agreements related to capital equipment and collaborative research arrangements. The source, timing and availability of any future financing will depend principally upon equity market conditions, interest rates and, more specifically, on the Company's continued progress in its exploratory, preclinical and clinical development programs. There can be no assurance that such funds will be available on favorable terms, if at all. 15 The Company expects that its existing capital resources, revenues from collaborative agreements and income earned on invested capital will be sufficient to fund its operations into the first half of 1998. The Company's cash requirements may vary, however, depending on numerous factors. Lack of necessary funds may require the Company to delay, scale back or eliminate some or all of its research and product development programs or to license its potential products or technologies to third parties. 16 PART II - ITEM 1 LEGAL PROCEEDINGS None.

Dear Sandra:

        This letter will confirm our understanding regarding your employment by

on the Starting Date, which will be July 22, 1996, unless we mutually agree on
an alternative Starting Date.

        2. Position and Duties. As President and Chief Operating Officer, you
will devote your full business time and best efforts to the advancement of the
Company's interests and to the performance of your duties and responsibilities
on the behalf of the Company, as these may be designated from time to time by
the Company's Chief Executive Officer. Those duties and responsibilities may
include without limitation various matters related to the Company's research
and development programs and clinical trials; the establishment by the Company
of, and performance under, corporate partnerships and other similar

operations plans; responsibility for various financial matters; general
management of the day-to-day operations of the Company and such other duties
and responsibilities as may be assigned to you from time to time by the
Company's Chief Executive Officer. In addition, at the first Board of Directors
meeting following your employment by the Company, you shall be elected as a
member of the Board of Directors of the Company (the "Board").

        3. Salary and Bonuses.

                a. Your base salary will be at the rate of $230,000 per year,
subject to review and adjustment from time to time by the Board, in its sole
discretion. Your base salary, as from time to time adjusted, is referred to in
this letter as your "Base Salary".

                b. In addition to your Base Salary, no later than two weeks
following the Starting Date, you will be paid a one-time cash bonus of $50,000.
If you terminate your employment with the Company other than for "good reason"
(as defined in Paragraph 7(d) within twelve (12) months of the Starting Date,
you will repay such bonus to the Company. Further bonuses, if any, may be paid
from time to time by the Board in its sole discretion.

 
   2
        4. Stock Options. Through the Company's Stock Option Plan, and subject
to the terms and conditions of such Plan, you will receive options to acquire
175,000 shares of common stock of the Company (the "Option Shares"). The
exercise price of these options will be determined as follows: You will receive
the maximum number of Incentive Stock Options (ISOs) as permitted by the
Internal Revenue Code; the remaining options will be issued as Non-Qualified
options at an option price equal to $11.00 or equal to the closing sale price
on the Starting Date, whichever is lower. Subject to your continued employment
by the Company, these options will vest over 48 months, as follows: (i) there
will be no vesting during the first twelve months; (ii) options to acquire
shares will vest on the first anniversary of your Starting Date; and (iii)
options to acquire 1/48th of such Option Shares will vest each month thereafter
for the next 36 months.

        5. Benefits. You will be entitled to participate in any or all employee
benefit plans, medical and dental insurance plans, life insurance, disability
income plans, savings plans and other benefit plans from time to time in effect
for senior management of the Company generally, except to the extent that such
plans are duplicative of benefits otherwise provided to you under this
Agreement. Such participation shall be subject to (i) the terms of the
applicable plan documents, (ii) generally applicable policies of the Company
and (iii) the discretion of the Board of Directors or any administrative or
other committee provided for in or contemplated by such plan. To the extent not
provided pursuant to the foregoing provisions of this Paragraph, the Company
shall provide you with life insurance in an amount equal to no less than the
lesser of (i) two times your base salary or (ii) $500,000, subject to any
requirement of the plan to show proof of good health.

        6. Confidentiality and Restricted Activities. You agree that some
restrictions on your activities during and after employment are necessary to
protect the goodwill, Confidential Information and other legitimate interests
of the Company;

                a. During your employment and thereafter, except as required by
applicable law or for the proper performance of your duties and
responsibilities hereunder, you shall not disclose to any other person,
corporation or other entity, or use for your own benefit or gain or otherwise,
any Confidential Information (as defined below). You understand that this
restriction shall continue to apply after your employment terminates,
regardless of the reason for such termination.

                b. While your are employed by the Company and for a period of
one (1) year thereafter you shall not, directly or indirectly, engage in any
activity, whether as owner, partner, investor, consultant, employee, agent or
otherwise, that is competitive with the business of the Company.

                c. You further agree that during your employment and for one
(1) year thereafter, you will not, directly or indirectly, attempt to hire any
employee of the Company, assist in such hiring by any other person, corporation
or entity, otherwise solicit, induce or encourage any employee of the Company
to terminate his or her relationship with the Company.

                d. You agree that you will not, during your employment with
the Company, improperly use or disclose any proprietary information or trade
secrets of any former or concurrent employer, or other such person or entity
with whom you have an agreement or duty to keep in confidence information
acquired by you in confidence, if any; and that you will not bring onto Company
premises any unpublished document or

                                       2

   3
proprietary information belonging to any such employer, person or entity,
unless consented to in writing by such employer, person or entity.

                e. At the time of leaving the Company's employ, you will
deliver to the Company (and not keep in your possession or deliver to anyone
else) any and all devices, records, data, notes, reports, proposals, lists,
correspondence, specifications, drawings, blueprints, sketches, materials,
equipment, other documents or property, or reproductions of any
aforementioned items developed by you pursuant to your employment with the
Company, or otherwise belonging to the Company, its successors or assigns, or
containing or constituting Confidential Information.

                f. You agree that the Company shall, in addition to any other
remedies available to it, be entitled to preliminary and permanent injunctive
relief against any breach by you of the covenants contained in this Paragraph
6, without having to post bond. In the event that any provisions of this
Paragraph shall be determined by any court of competent jurisdiction to be
unenforceable by reason of its being extended over too great a time, too large
a geographic area or too great a range of activities, it shall be interpreted
to extend only over the maximum period of time, geographic area or range of
activities as to which it may be enforceable.

                g. For purposes of this Agreement:

                        i. A business shall be deemed to be competitive with
the Company if it engages or proposes to engage in any business activity (i)
utilizing or seeking to develop technology capable of utilizing the
transplantation of cells as a therapeutic agent for the diagnosis, prevention or
treatment of human disease, injury or condition or (ii) in any field the
Company is currently pursuing or has pursued within the previous two years.

                        ii. Confidential Information means any and all
information of whatever type (including, without limitation, data, results,
technology and all other information) of or relating to the Company including,
without limitation, information relating to (1) the development, research,
testing, production and marketing activities of the Company, (2) the products
and services of the Company, (3) patients and clinical trails, (4) the costs,
sources of supply and strategic plans of the Company, (5) the identity and
special needs of the customers of the Company, (6) patents, trade secrets and
other intellectual property and (7) people and organizations with whom the
company has business relationships and those relationships. Confidential
Information also includes comparable information that the Company has received
or may receive in the future of or relating to third parties where the Company
has a duty to keep such information confidential. Confidential Information does
not, however, include information that has become publicly known and generally
available other than through a wrongful act by you.

        7. Termination and Termination Benefits. Your employment with the
Company is "at will", which means that either you or the Company may terminate
your employment at any time, with or without cause or good reason.

                a. The Company may terminate your employment other than for
"cause" at any time upon written notice to you and, in that event, (i) the
Company will continue to pay you your Base Salary for the Severance Period (as
defined below) or until you obtain other employment, whichever occurs first and
(ii) all options which would have become vested during such Severance Period
shall be treated as vested at the time of such termination. If, under these
circumstances, you obtain other employment within the

                                       3

   4
Severance Period, the Company will pay you the amount, if any, by which your
Base Salary exceeds your total compensation from your new employment for the
remainder of the Severance Period. The Severance Period shall be six months
plus two weeks for each completed continuous year of employment with the
Company, up to a maximum period of nine months. Notwithstanding any other
provision of this Agreement, if the value of your Option Compensation is
greater than eight times your Base Salary, the Company shall have no obligation
to continue to pay your Base Salary following your termination. Option
Compensation shall mean an amount equal to the sum of the following
(determined, in each case, by reference to the last closing sale price of the
Company's Common Stock prior to the date of your termination and including
options awarded to you by the Company pursuant to this Agreement or otherwise):
(i) the aggregate spread on all your vested but unexercised in-the-money stock
options; (ii) the market value of any stock of the Company obtained by you on
exercise of your stock options and still held by you, less the aggregate
exercise price paid by you to obtain such stock; and (iii) the proceeds
realized by you on the sale of any stock obtained by you on exercise of your
stock options, less the aggregate exercise price paid by you to obtain such
stock. In the event that you purchase stock from the Company (other than
through the Company's Employee Stock Purchase Plan, the Company's 401(K) plan
or as part of and on the same terms as a public or private offering of
securities to investors) or are granted stock by the Company, Option
Compensation shall also include (i) an amount equal to the market value of any
such stock still owned by you, less the amount paid by you for such stock and
(ii) the amount realized by you on the sale of any such stock sold by you, less
the amount paid by you for such stock. For these purposes, the Company's stock
shall be considered to have a "value" only if there is a market for the stock
or the Company will agree to repurchase such options provided the Company has
sufficient liquidity. Stock options will not continue to vest after your
termination in the event of a resignation without good reason or termination
with cause.

        b. The Company may terminate your employment upon written notice to you
in the event that you become disabled during your employment through any
illness, injury, accident or condition of either physical or psychological
nature and, as a result, you are unable to perform substantially all of your
duties and responsibilities hereunder for ninety (90) days during any three
hundred and sixty-five calendar days. In that event, the Company will continue
to pay you your Base Salary (i) for a period of six (6) months following such
termination; (ii) until you obtain other employment; or (iii) until you become
eligible for disability income under any disability income plan provided by the
Company, whichever of these events shall occur first.

        c. The Company may terminate your employment hereunder for cause at any
time upon written notice to you setting forth in reasonable detail the nature
of such cause. The following as determined by the Company in its reasonable
judgment, shall constitute "cause" for termination:

        (1) Your failure to perform, or material negligence in the performance
        of, (i) your principal duties and responsibilities to the Company
        (which, to the extent assigned to you, shall include those duties and
        responsibilities described in Section 2) or (ii) any other of your
        duties and responsibilities following written notice from the Company
        and a 10-business day opportunity to cure any curable failure or
        negligence; 

        (2) Any misconduct by you which is substantially injurious to the 
        business or interests of the Company;



                                       4
   5
        (3) Your violation of any federal, state or local law, regulation or
        other requirement applicable to the business of the Company;
        
        (4) Your conviction of, plea of "no contest" to, any felony; or

        (5) Any material breach by you of any provision of this Agreement.

        d. You may terminate your employment at any time, with or without good
reason, upon written notice to the Company. If you terminate your employment
with good reason, the Company will be obligated to you to the same extent as if
the Company had terminated your employment other than for cause, and the
Provisions of Paragraph 7 (a), including the acceleration of option vesting and
the limitations on the Company's obligations contained therein, shall apply.
The following shall constitute "good reason" for termination: material breach
by the Company of any provision of this Agreement which breach continues for
more than ten (10) business days following written notice from you to the 
Company setting forth in reasonable detail the nature of such breach.

        e. If you resign other than for good reason or your employment is
terminated by the Company for cause, the Company shall have no further
obligation to you other than for Base Salary earned through the date of
termination. No severance pay or other benefits of any kind will be provided.

    8. Withholding. All payments and reimbursements made by the Company under
this Agreement shall be reduced by any tax or other amounts required to be
withheld by the Company under applicable law.

    9. Assignment. This Agreement shall inure to the benefit of the Company and
any successor of the Company by reorganization, merger, consolidation or
liquidation and any assignee of all or substantially all of the business or
assets of the Company or any division or line of business of the Company with
which you are associated. The Company requires your personal services and you
may not assign this Agreement.

    10. Waiver. Except as otherwise expressly provided in this Agreement, no
waiver of any provision hereof shall be effective unless made in writing and
signed by the waiving party. The failure of either party to require performance
of any term or obligation of this Agreement, or the waiver by either party of
any breach of this Agreement, shall not prevent any subsequent enforcement of
such term or obligation or be deemed a waiver of any subsequent breach.

    11. Severability. Should any provision of this Agreement, or portion
thereof, be found invalid in any circumstance, such invalidity shall not affect
any other provision or circumstance, and such provision shall be construed by
limiting it so as to be enforceable to the maximum extent compatible with
applicable law.

    12. Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be in writing and shall be effective when
delivered in person or deposited in the United States mail, postage prepaid,
registered or certified, and addressed to you at your last known address on the
books of the Company or, in the case of the Company, at its main office,
attention of the Chief Executive Officer.

    13. Captions. The captions and headings in this Agreement are for
convenience only and in no way define or describe the scope or content of any
provision of this Agreement.


                                       5

        14.  Entire Agreement.  This Agreement sets forth the entire agreement
and understanding between you and the Company and supersedes all prior
communications, agreements and understandings, written and oral, with respect to
the terms and conditions of your employment. This Agreement may not be changed
or modified except by an agreement in writing signed by you and the Chief
Executive Officer or other specifically authorized representative of the
Company.

        15.  Governing Law.  This Agreement shall be governed, construed and
enforced in accordance with the laws of Rhode Island, without regard to
principles of conflicts of law.

        16.  No Conflicting Agreements.  You hereby represent to the Company
that neither your execution and delivery of this Agreement nor your acceptance
of employment with the Company nor your anticipated service as President, Chief
Operating Officer and a Director of the Company will conflict with or result in
a breach of any of the terms, conditions or provisions of any agreement to which
you are a party or any order, injunction, judgment or decree of any court or
governmental authority or any court or governmental authority or any arbitration
award applicable to you.

        17.  Inventions.  You hereby represent to the Company and agree that,
except as described on Exhibit A, you have no inventions, original works of
authorship, developments, improvements or trade secrets that were made by you
prior to your employment with the Company and which relate to the Company's
current or proposed business, products, or research and development. You will
promptly make full written disclosure to the Company, hold in trust for the
Company's sole right and benefit, and hereby assign to the Company or its
designee, all of your right, title and interest in any and all inventions,
original works of authorship, developments, concepts, improvements or trade
secrets, whether or not patentable or registerable under copyright or similar
laws, that you may solely or jointly conceive, develop, reduce to practice or
cause to be conceived or developed, or reduced to practice, during the period of
time you are employed by the Company (collectively referred to as the
"Inventions"). You further acknowledge that all original works of authorship
made by you solely or jointly with others within the scope of your employment
and protectible by copyright are "works made for hire", as that term is defined
in the United States Copyright Act. You agreed to keep and maintain adequate and
current records of all inventions made by you solely or jointly with others
during the term of your employment with the Company. Such records will be in the
form of notes, sketches, drawings or any other format that may be specified by
the Company. These records will be available through, and remain the sole
property of, the Company at all times. You agree to assist the Company or its
designee, at the Company's expense, in every proper way, to secure the
Company's rights in the Inventions and copyrights, including the disclosure to
the Company of all pertinent information and data with respect thereto, the
execution of all applications, specifications, oaths, assignments and all other
instruments that the Company shall deem necessary in order to apply for and
obtain such rights, and in order to assign and convey to the Company, its
successors, designees and nominees the sole and exclusive right, title, and
interest in and to such Inventions, and any copyrights, patents, or other
intellectual property rights relating thereto, both during your employment by
the Company and thereafter. In the event that the Company is unable for any
reason to secure or to prosecute any patent application with respect to such
Invention (including, without limitation, renewals, extensions, continuations,
divisions or continuations in part thereof), you hereby irrevocably designate
and appoint the Company and its duly authorized officers and agents, as your
agents and attorney-in-fact to act for and in your behalf and  


                                       6

   7
instead of you, to execute and file any such application and to do all other
lawfully permitted acts to further the prosection and issuance of patents
thereon with the same legal force and effect as if executed by you. You agree
that you will assist the Company in the prosecution and enforcement of the
Company's intellectual property after termination of your employment, at the
Company's expense.

        18.  Compliance With Agreement.  The Company's obligations under this
Agreement and its obligation to deliver stock under the terms of the stock
options granted pursuant to the terms of this Agreement (or otherwise granted
to you during the course of your employment) are conditioned on your compliance
with the terms and conditions of this Agreement and the accuracy of the
representations made to the Company by you herein.

        If the foregoing is acceptable to you, please sign the enclosed copy of
this letter in the space provided below and return it to me, whereupon this
letter and such copy will constitute a binding agreement between you and the
Company on the basis set forth above as of the date of the first above written.

                                        Sincerely yours,

                                        CYTOTHERAPEUTICS, INC.

                                                                  EXHIBIT 10.56

                           CONVERTIBLE LOAN AGREEMENT

         This Agreement dated as of July 10, 1996, is among Modex Therapeutiques
SA, a Swiss corporation ("Modex") and CytoTherapeutics, Inc. ("CTI"), a Delaware
corporation.

         CTI currently owns 6'500 shares of Modex common stock.

         Modex wishes to borrow from CTI, and CTI wishes to lend to Modex, a
total amount of SFr. 3'600'000.--in the form of a convertible subordinated loan.

         Parties refer to Section 7 of the Statutes of Modex which provides for
a conditional capital stock increase, in order to enable Modex to issue the
necessary number of shares required in case of conversion of the hereunder
defined loan, and of the loan agreed today with Societe Financiere Valoria SA,
another shareholder of Modex.

         Parties agree as follows:

1.       Total Amount of Loan

         The total amount of the loan is of SFr. 3'600,000.--

2.       Delivery of the Funds by CTI

         2.1.     CTI will immediately provide for a transfer to the bank
                  account of Modex at Banque Cantonale Vaudoise no.-911.58 12
                  the amount of SFr. 1'200'000.--. Modex will acknowledge
                  receipt of that amount and acknowledge owing SFr.
                  1'200'000.--to CTI, with reference to the present Agreement.

         2.2.     On the second anniversary of the present Agreement, a similar
                  transfer of the amount of SFr. 1'400'000.-- will be made by
                  CTI, provided that on or before such second anniversary Modex
                  has achieved one of the following milestones (1) anemia: the
                  earlier of (a) delivery for at least 90 days of 300 units per
                  day of EPO in a large animal model or functional evidence of a
                  therapeutic benefit of EPO in large animal model or (b)
                  commencement of a Phase I clinical trial in humans or (2)
                  diabetes: large animal off insulin for 90 days or (3) obesity:
                  the earlier of (a) FaFa rat returned to normal body weight or
                  (b) demonstrated weight loss in large animal model or in
                  humans. Modex will acknowledge receipt of that amount
                  similarly.


 
   2
3.       Repayment of Loan by Modex

         All unpaid principal shall be due and payable on the earlier to occur
         of the tenth anniversary of the CTI/LOC Option Agreement or the closing
         of an underwritten public offering of Modex common stock (such date is
         referred to as "Due Date").

         Reservation is made for provisions of Section 6.2 hereunder.

4.       Prepayment

         Modex may not prepay any portion of the principal sum prior to the Due
         Date, unless authorized to do so in writing by CTI.

5.       Interest

         No interest shall be due on the principal.

6.       Subordination

         6.1.     Principle

                  In the event of any receivership, insolvency or bankruptcy
                  proceedings instituted by or against Modex, or execution sale
                  of any of the assets of Modex, or proceedings, whether or not
                  judicial, for dissolution or liquidation of Modex, or any
                  distribution or division, partial ro complete, of all or any
                  part of the assets of Modex, the claim derived from this loan
                  agreement and that of other loans similarly subordinated will
                  be subordinated to the payment in full of all third party
                  claims (classes 1 - 5 according to Article 219 of Swiss
                  Bankruptcy Law).

         6.2.     Possibility of Conditional Waiver

                  Furthermore, before any receivership, insolvency or bankruptcy
                  proceedings, in the event that excessive debt of Modex would
                  require steps to be taken according to Article 725 of the
                  Swiss Code of Obligations, CTI will accept, unless it
                  exercises its conversion option according to Section 7
                  hereunder, to draft an agreement, together with the holders of
                  other subordinated loans, according to which its claim against
                  Modex would be conditionally waived, i.e. until the balance
                  sheet of Modex would show again that the assets cover all
                  loans.

7.       Conversion

         7.1.     Conversion at the Option of CTI

                                       -2-

 
   3
                  At the option of CTI, all or part (corresponding to the
                  conversion of any possible number of shares) of the unpaid
                  principal then outstanding may be converted into shares of
                  common stock of Modex, at any time starting from the day after
                  the first payment according to Section 2.1 until Due Date,
                  providing that CTI gives a thirty day notice in writing

         7.2.     Conversion Price

                  Subject to adjustment as provided in Sections 7.3 and 7.7
                  below, the price per share of common stock into which the part
                  of outstanding loan shall be converted is SFr. 1'400.--.
                  However, in the event that Modex has failed to complete one at
                  least of the milestones set forth in Section 2.2 here above by
                  midnight, on the second anniversary of this Agreement, then
                  the initial conversion price, still subject to adjustments as
                  set forth below, shall be deemed to be SFr. 480.- per share.
                  Upon such conversion, the amount of outstanding principal so
                  converted shall be deemed paid and no longer outstanding
                  hereunder.

         7.3.     Adjustments to Conversion Price

                  In the event the outstanding shares of common stock shall be
                  combined or consolidated (by reclassification or otherwise)
                  into a lesser number of shares of common stock, the conversion
                  price in effect immediately prior to such combination or
                  consolidation shall, concurrently with the effectiveness of
                  such combination or consolidation, be proportionately
                  increased. In the event the outstanding shares of common stock
                  shall be subdivided (by stock split, by stock dividend or
                  otherwise) into a greater number of shares of common stock,
                  the conversion price in effect immediately prior to such
                  subdivision shall, concurrently with the effectiveness of such
                  subdivision, be proportionately decreased.

         7.4.     Conversion Modalities

                  CTI will notify Modex in writing, with the thirty day notice
                  mentioned at Section 7.1, its will to exercise the option to
                  convert, specifying the number of shares converted and the
                  amount of the loan paid, and the day of the conversion. Such
                  notice will refer to Section 7 of the Statutes of Modex
                  related to the conditional increase of capital.

                  No later than the day of conversion, CTI will serve a formal
                  declaration of compensation to Banque Cantonale Vaudoise
                  (Article 653 e) al.2 of the Swiss Code of Obligations).

                                       -3-

 
   4
         7.5.     Dividend

                  Modex shares obtained through conversion will give the right
                  to receive all dividends payable with respect to such shares
                  by Modex following such conversion.

         7.6.     Stamp duty

                  The stamp duty levied by the capital increase will be paid by
                  Modex.

         7.7.     Conversion at the Option Market

                  At the option of Modex, all or part (corresponding to the
                  conversion of any possible number of shares) of the unpaid
                  principal then outstanding may be converted into shares of
                  common stock of Modex on (i) the closing of an underwritten
                  public offering of the common stock of Modex or (ii) the Due
                  Date. The conversion price shall be as provided in Section 7.2
                  above, and shall be subject to the adjustments provided in
                  Section 7.3. Conversion at the closing of a such public
                  offering shall be automatic. Conversion on the Due Date shall
                  occur if Modex shall have so notified CTI at least 30 days
                  prior to Due Date. Such notice shall refer to Article 7 of the
                  Statutes of Modex related to the conditional increase of
                  capital. No later than one day of any conversion under this
                  Section 7.8, CTI will serve a formal declaration of
                  compensation to Banque Cantonale Vaudoise (Art. 653 e) lit. b
                  of Swiss Code of Obligations).

8.       Attorney's Fees

         If the principle is not paid in full when due, Modex hereby agrees to
         pay to CTI, in addition to such amount owed to pursuant to the loan,
         all costs and expenses of collection, including a reasonable sum for
         attorneys fees.

9.       Course of Dealing

         No course of dealing between Modex and CTI shall operate as a waiver of
         any of CTI's rights according to the loan. No delay or omission on the
         part of CTI, in exercising any right according to the loan, shall
         operate as a waiver of such right. No amendment or waiver hereof shall
         be binding unless it is in writing and signed by CTI.

10.      Governing Law

         This Agreement shall be governed by and construed in accordance with
         the internal laws of Switzerland.

                                       -4-

 
   5
11.      Dispute Resolution

         All disputes, differences, controversies or claims arising in
         connection with, or questions occurring under, this Agreement shall be
         settled as provided in Exhibit A.

the obligation of such Sublicensees not to sell Licensed Products outside, in
the case of the Modex Sublicensees, the Modex Field, and, in the case of CTI

hereunder by CTI shall terminate for any reason, any Sublicensee under any such
terminated license shall continue automatically to have the rights and license
previously licensed by CTI to Modex under such terminated license and shall be
entitled to enforce such rights and license directly against CTI, provided that
any such Sublicensee agrees in writing with CTI that CTI shall be entitled to
enforce the provisions of such terminated license directly against such
Sublicensee. In the event that the license granted to CTI hereunder by Modex
shall terminate for any reason, any Sublicensee under any such terminated
license shall continue automatically to have the rights and license previously
licensed by Modex to CTI under such terminated license and shall be entitled to
enforce such rights and license directly against Modex, provided that any such
Sublicensee agrees in writing with Modex that Modex shall be entitled to enforce
the provisions of such terminated license directly against such Sublicensee. At
the request of either Party, the other Party shall enter into a direct
contractual arrangement with any Sublicensee of the requesting Party providing

the other Party with reasonable cooperation in order to permit each such Party
to exploit the rights granted to it hereunder.

         2.7. Other Agreements. Nothing in this Agreement (including without
limitation the provisions of Section 2) shall limit in any way, and the rights

                  respect to some or all of the shares of CTI Common Stock to be
                  issued to Modex on achievement of such milestone, to comply
                  with the restrictions contained in subparagraph (b) below,

                  shares so issued pursuant to Regulation S are referred to
                  herein as the "Regulation S Shares." Any shares of CTI Common
                  Stock (the "Private Placement Shares") to be issued to Modex
                  hereunder other than Regulation S Shares shall be issued to
                  Modex by CTI pursuant to the so-called "private placement"
                  exemption to the registration requirements of the Securities
                  Act under Section 4(2) of the Securities Act and shall be
                  subject to the restrictions contained in subparagraph (c)
                  below.

         (b)      Restrictions Applicable to Regulation S Shares. During the 40
                  day period commencing on the date of issuance of Regulation S
                  Shares to Modex (the "Restricted Period"), Modex agrees not to
                  offer or sell any Regulation S Shares (i) in the United States
                  or (ii) to or for the account or benefit of a "U.S. Person"
                  (as defined in Rule 902(o) of Regulation S). Modex
                  acknowledges and agrees that CTI will not authorize any
                  transfer or sale of any Regulation S Shares in the United
                  States or to a U.S. Person other than in accordance with
                  Regulation S and U.S. federal securities laws. In connection
                  with the issuance to Modex of any Regulation S Shares, Modex
                  will not engage in any prearranged transfer of any such shares
                  by Modex to any purchaser located in the United States or any
                  purchaser who is a U.S. Person or take any other action which
                  is part of any plan or scheme to evade the registration
                  provisions of the Securities Act. During the Restricted
                  Period, Modex will not enter into any arrangement or
                  understanding to resell any Regulation S Shares, or enter into
                  any put option, short position or similar instrument or
                  position with respect to such Shares. The Regulation S Shares
                  may be transferred by Modex to consultants or employees of
                  Modex provided (i) that any such transfer occurs outside the
                  United States, (ii) that any such transferee is not a U.S.
                  Person and is not acquiring such CTI Common Stock for the
                  account or benefit of a U.S. Person and (iii) that any such
                  transferee is bound or agrees to be bound by the same
                  restrictions applicable to Modex with respect to such shares
                  hereunder (including the provisions of subparagraph (d)). Each
                  certificate representing Regulation S Shares shall bear a
                  legend in substantially the form set forth below:

                           The securities represented by this certificate have
                           not been registered under the U.S. Securities Act of
                           1933, as amended (the "Securities Act"), and have
                           been issued pursuant to an exemption from the
                           registration requirements of the Securities Act
                           pursuant to Regulation S under the Securities Act.
                           These shares cannot be transferred, offered or sold
                           in the United States or to a U.S. Person (as that
                           term is defined in Regulation S) unless any such
                           transfer, offer or sale is registered under

                           the Securities Act or is exempt from such
                           registration. The offer or sale of these shares to a
                           U.S. Person (as such term is defined in Regulation S)
                           or in the United States is subject to certain
                           restrictions as set forth in a Cross License
                           Agreement dated July 10, 1996 between the issuer and
                           the original holder of these shares, a copy of which
                           will be made available to any subsequent holder by
                           the issuer upon request.

         (c)      Restrictions Applicable to Private Placement Shares. Modex
                  acknowledges and agrees that the Private Placement Shares are
                  being transferred to Modex pursuant to an exemption from the
                  registration requirements of the Securities Act and
                  accordingly, must be held indefinitely by Modex unless they
                  are later transferred in a transaction that is either
                  registered under the Securities Act or exempt from such
                  registration. Modex agrees not to sell or otherwise dispose of
                  the Private Placement Shares in violation of the provisions of
                  the Securities Act. Modex understands that CTI is under no
                  obligation to register the Private Placement Shares under the
                  Securities Act or to file for or comply with an exemption from
                  registration, and recognizes that exemptions from
                  registration, in any case, are limited and may not be
                  available when Modex may wish to sell, transfer or dispose of
                  the shares. Modex acknowledges that the Private Placement
                  Shares are "restricted securities" as such term is defined in
                  Rule 144 under the Securities Act and may be transferred under
                  such Rule only in compliance with the terms and conditions of
                  such Rule, including the holding periods provided for therein.
                  The Private Placement Shares may be transferred by Modex to
                  consultants or employees of Modex provided that any such
                  transferee is bound or agrees to be bound by the same
                  restrictions applicable to Modex with respect to such shares
                  hereunder (including the provisions of subparagraph (d)). Each
                  certificate representing Private Placement Shares shall bear a
                  Legend substantially the form set forth below:

                           The shares of stock represented by this certificate
                           have not been registered under the Securities Act of
                           1933, as amended, and may not be sold, signed,
                           pledged or otherwise transferred in the absence of an
                           effective Registration Statement under the Securities
                           Act covering such transfer or an opinion of counsel
                           satisfactory to the issuer that registration under
                           such Act is not required.

         (d)      Market Stand-Off Provisions Applicable to All CTI Shares.
                  Modex hereby acknowledges and agrees that, without the prior
                  written consent of CTI, Modex will not, directly or
                  indirectly, offer, sell, contract to sell, cause or in any way
                  permit to be sold or otherwise dispose of the shares of CTI
                  Common Stock acquired hereunder for a period of 90 days
                  beginning on the effective date of a

                                       -9-


   14



                  registration statement under the Securities Act relating to an
                  underwritten public offering of CTI Common Stock (or
                  securities convertible into such Common Stock) or at such
                  earlier or later time as may be agreed to in writing by the
                  selling stockholders in such offering or stockholders who own
                  in the aggregate at least 20 percent of CTI's outstanding
                  shares of Common Stock immediately prior to such offering.

         3.4. Termination of Royalty Obligations. With respect to each Licensed
Product in each country, the royalty obligations of each of Modex and CTI shall
cease upon the later of (i) the last to expire of the patents covering such
Licensed Product in such country, and (ii) the date that is ten years from the
First Commercial Sale of such Licensed Product.

         3.5. Payment Dates and Statements. Within forty-five (45) days of the
end of each calendar quarter in which Net Sales occur, each Party shall
calculate the royalty amount owed under this Section 3 and shall remit such
amount to the other Party. Such payment shall be accompanied by a statement
showing the calculation of the amount owed for each country, the total Net Sales
of each Licensed Product by country for that quarter, and the exchange rate (as
determined pursuant to Section 3.6) used to directly convert any royalty amounts
into Dollars. For purposes of determining when a sale of a Licensed Product
occurs, the sale shall be deemed to occur on the earlier of: (i) the date the
Licensed Product is shipped by CTI, or (ii) the date of the invoice to the
purchaser of the Licensed Product. Any payment owed under this Section 3 that is
not paid on or before the date such payment is due under this Agreement shall
bear interest, to the extent permitted by applicable law, at two percentage
points (2%) over the prime rate of interest as reported in the New York edition
of The Wall Street Journal on the due date of such payment calculated on the
number of days such payment is delinquent.

         3.6. Records and Accounting. Each Party shall keep, and shall cause its
Sublicensees to keep, complete and accurate records of the latest three (3)
years of its Net Sales. Each Party shall have the right annually at its own
expense to have an independent, certified public accountant to which the other
Party has no reasonable objection, review such records upon reasonable notice
and during reasonable business hours for the purposes of verifying royalties
payable to it hereunder and Net Sales by the other Party and its Sublicensees.
Results of such review shall be made available to both parties. If the review
reflects an underpayment of royalties, such underpayment shall be promptly
remitted to the Party to whom such royalties are payable with interest as
provided in Section 3.4. If the underpayment is equal to or greater than five
percent (5%) of the royalty amount that was otherwise due, the Party to whom
such royalties are payable shall be entitled to have the other Party pay all of
the costs of such review. Each Party shall cause its accountant undertaking a
review of the other Party's records pursuant to this Section 3.5 to treat all
information of such Party's records as Confidential Information of such Party
and such accountant shall disclose to its client only such information as is
relevant to determining the accuracy of the royalties paid.

         3.7. Currency of Payments. All payments under this Agreement shall be
made in Dollars by wire transfer to such bank account as the Party to whom
royalties are payable may designate from time to time. Any payments due
hereunder on Net Sales outside of the United States shall be payable in Dollars
at the rate of exchange of the currency of the country in which the Net Sales
are made as reported in the New York edition of The Wall Street Journal for the
last business day of the quarter for which the royalties are payable. Where
royalties are due hereunder for Net Sales in a country where, by reason of
currency regulations or taxes of any kind, it is illegal for the Party obligated
to transfer royalty payments out of such country for Net Sales in that country,
such royalties shall be deposited in a currency that is permitted for the Party
not able to make the transfer for the benefit or credit of the other Party.

         3.8. Tax Withholding. Modex and CTI shall use all reasonable and legal
efforts to reduce tax withholding on payments made to hereunder. Notwithstanding
such efforts, if the Parties conclude that tax withholdings are required with
respect to payments made hereunder. The Party making such payments shall
withhold the required amount and pay it to the appropriate governmental
authority. In such a case, the Party paying such amount will promptly provide
the other Party with original receipts or other evidence sufficient to allow the
other Party to obtain the benefits of such tax withholdings.

         4.   PATENTS AND TECHNOLOGY

         4.1. Ownership of Technology. Each Party shall retain sole title to any
technology which it develops solely. Except as provided in this Agreement,
neither Party shall have any right to use or license technology to which the
other Party has sole title. Each Party shall own a 50% undivided interest in all
technology, know-how, inventions, concepts, processes and the like (whether or
not patentable) made, conceived, reduced to practice or generated jointly by or
on behalf of both parties ("Joint Technology").

         4.2. Modex Technology. CTI shall prepare, file and prosecute patent
applications claiming any technology which Modex may from time to time develop.
Modex shall reimburse CTI for reasonable expenses incurred by CTI in connection
with such patent application or the maintenance of any patents issuing thereon.
In the event Modex proposes to withdraw or abandon any of such patent
applications, CTI shall have the option for a period of 30 days to assume the
rights to such patent or patent application. Following such abandonment or
withdrawal Modex shall have no further rights under the patent or patent
application in question and no further obligation to pay for the costs
associated therewith, provided that such patent or patent application shall
remain subject to the licenses hereunder.

         4.3. Joint Patents. CTI shall prepare, file and prosecute patent
applications, covering any Joint Technology in the countries of CTI's choice
with appropriate credit to Modex, including naming representatives of Modex as
inventors where appropriate. CTI and Modex shall share equally all of the costs
associated with the preparation, filing and

                                      -11-


   16



prosecution of such patent applications in such countries. The parties shall
assist each other to the maximum extent reasonable in securing intellectual
property rights resulting from their respective research programs. Either Party
may withdraw from or abandon any jointly-owned patent or patent application, on
notice to the other in which case any such patent or patent application shall
become the sole property of the other Party.

         4.4. Infringement of Patents. If a Party has reason to believe that any
of the patents of the other is being infringed by a third Party, the former
shall promptly notify the latter and shall provide it with any evidence of any
infringement which is reasonably available. The Party owning such patent shall
have the first opportunity at its own expense to attempt to resolve such
infringement by appropriate steps including suit. In such event, the other Party
will assist in taking such steps, including suit, within reasonable limits, and
any amount recovered as a result thereof shall first be applied to reimbursing
the Party taking such action for its out-of-pocket expenses, then for
reimbursing the other Party for its out-of-pocket expenses incurred in
connection with such action, and the remainder, if any, shall be for the account
of the Party owning such patent. In the event the Party owning such patent fails
to cause such infringement to cease or institute suit or other legal action with
respect to any such infringement within a period of six months following such
notice of infringement, the other Party shall have the right to take any
appropriate steps, including filing suit against the infringer at its own
expense and in the name of the Party owning the patent, if necessary. In such
event, the other Party shall assist the Party bringing suit as reasonably
requested and shall permit the Party bringing suit to prosecute such
infringement in the name of the owner of the patent. The expenses reasonably
incurred in taking such steps, including suit and legal action, and any amount
recovered as a result thereof shall be first applied to reimbursing the Party
taking such action for out-of-pocket expenses, and then to reimbursing the Party
not taking such action for its out-of-pocket expenses incurred in connection
with such action, and the remainder, if any, shall be for the account of the
Party taking such action.

         4.5. Survival. This Section 4 shall survive the termination or
expiration of this Agreement.

         5.   CONFIDENTIAL INFORMATION

         5.1. Treatment of Confidential Information. Each Party hereto shall
maintain the Confidential Information of the other Party in confidence, and
shall not disclose, divulge or otherwise communicate such Confidential
Information to others, or use it for any purpose, except pursuant to, and in
order to carry out, the terms and objectives of this Agreement, and each Party
hereby agrees to exercise every reasonable precaution to prevent and restrain
the unauthorized disclosure of such Confidential Information by any of its
directors, officers, employees, consultants, subcontractors, sublicensees or
agents.

         5.2. Release from Restrictions. The provisions of Section 5.1 shall not
apply to any Confidential Information disclosed hereunder which is: required to
be disclosed by the

                                      -12-


   17



receiving Party to comply with applicable laws, or to comply with laws or
regulations (including without limitation testing and marketing regulations), in
each case only to the extent required to carry out the work contemplated by this
Agreement or other legal obligations provided that the receiving Party provides
prior written notice of such disclosure to the other Party and takes reasonable
and lawful actions to avoid and/or minimize the degree of such disclosure.

         5.3. Confidential Agreements. Each Party shall maintain employment
agreements with their respective employees and representatives providing for
confidentiality and nonuse commitments consistent with its obligations hereunder
and will require all of their employees, consultants, agents or others who have
access to any Confidential Information of the other Party to execute
confidentiality agreements covering all Confidential Information subject to
Section 5 and will exercise its reasonable best efforts to obtain compliance
therewith.

         6.   SUPPLY OF MODEX LICENSED PRODUCT

         6.1. General. CTI will have the option to manufacture and supply all or
any portion of the Modex Licensed Products and other implants (e.g. placebos for

Modex Licensed Products and other implants for research, clinical trials and
commercial sale.

         6.2. Supply of Modex Licensed Product for Clinical Trials. The transfer
price to Modex of all Modex Licensed Products and other implants used in the

be required to supply more than 10 implants in any week through the completion
of Phase II clinical trials and no more than 25 implants per week during Phase
III clinical trials. Modex shall provide CTI with reasonable lead time to

                  6.3.1 Transfer Price. The transfer price for all Modex
Licensed Products other than those used in such clinical trials shall be

Price"):


         CTP = [****** *******]

             Where: CTP = Commercial Transfer Price

                     FBMC  =    CTI's Fully Burdened Manufacturing Cost of such
                                Modex Licensed Product


           *  This confidential portion has been omitted and filed

                  6.3.2 Estimate of Need for Modex Licensed Product. At least
two (2) years before the expected first launch of any Modex Licensed Product in
any country, Modex shall inform CTI of its best estimate of the quantity of such
Modex Licensed Product needed by Modex for use or sale during the initial two
(2) years after launch. Such estimates will thereafter be updated annually.

                  To assist CTI in preparing for its supply of Modex Licensed
Product, Modex will provide CTI with the following "signals" for each Licensed
Product:


Signal                  Timing                Forecast
- ------                  ------                --------
                                       
1       Prior to Phase II studies        Market potential estimates based on
                                         market research.
                                             
2       Prior to Phase III studies       Market potential estimate based on
                                         more comprehensive market research,
                                         targeted indications or suggested by
                                         Phase II data.

3       Prior to 1st Worldwide           Final pre-launch forecast based on   
        NDA filing or similar            extensive market research using Phase
        filing (1-1 1/2 yrs before       III results and considering 
        launch)                           reimbursement issues. 
The estimates given by Modex pursuant to this Paragraph 6.3.2 will be used by CTI only for the purpose of preparing CTI's production capacity for Modex Licensed Product. 6.3.3 Quarterly Forecast. Starting twelve (12) months prior to the expected first launch, Modex will, before each January 1, April 1, July 1 and October 1, present to CTI a written forecast estimating the monthly quantities of Modex Licensed Products to be delivered during the next twelve (12) month period. With such forecast, Modex will provide CTI with a summary of its inventory, if any. Modex will place firm orders for delivery not less than ninety (90) days prior to the start of the calendar quarter for which shipment is ordered, and CTI will be obliged (subject to such orders being within CTI's supply capacity), to deliver all ordered quantities of Modex Licensed Product by the delivery date stated in the order, except to the extent that such delivery would exceed either of the following: (a) 130% of the twelve (12) months forecast for such quarter made twelve (12) months prior to the start of such quarter; and -14- 19 (b) 120% of the six (6) months forecast for such quarter made six (6) months prior to the start of such quarter. Similarly, such firm order shall not be less than either of the following: (c) 70% of the twelve (12) months forecast for such quarter made twelve (12) months prior to the start of such quarter; and (d) 80% of the six (6) months forecast for such quarter made six (6) months prior to the start of such quarters. In addition, the firm order for any quarter shall not require delivery of more than forty percent (40%) of such order in any one month. CTI will, however, make reasonable efforts also to supply quantities of Modex Licensed Product in excess of forecast amounts if ordered by Modex. 6.3.4 Payment and Delivery Terms. Each delivery of Modex Licensed Product will be effected ex works (CTI's plant) (Incoterms 1990 as published by the International Chamber of Commerce). All quantities of Modex Licensed Product will be delivered in finished form, ready for sale and suitably packed for transportation. Payment for Modex Licensed Products shall be made upon delivery. 6.3.5 Circumstances Affecting Supply. Each party will promptly notify the other party of any circumstances that it believes may be of importance as to CTI's ability to supply Modex with Modex Licensed Product. 6.4. Specifications. All Modex Licensed Products manufactured by CTI pursuant to this Agreement shall, upon delivery to Modex, conform to the specifications for such Modex Licensed Product to be agreed upon by Modex and CTI. 6.5. Additional Manufacturing Facility. If prior to the termination of Modex' rights and licenses hereunder, the parties determine that CTI will be required to construct an additional facility to meet the demand for the supply of Modex Licensed Products, CTI agrees to use reasonable efforts to locate such facility in Switzerland. CTI's obligation to use reasonable efforts to construct such facility in Switzerland is subject to CTI's determination that such facility would be commercially practicable in light of the demand for CTI's other products and the agreement by the Parties on minimum purchase obligations on the part of Modex that would make such facility profitable. CTI would be permitted to utilize any such facility for the manufacture of products other than Modex Licensed Products. 7. TERM AND TERMINATION -15- 20 7.1. Term. The term of this Agreement (the "Term") shall commence as of the Effective Date. Unless sooner terminated pursuant to Section 7.2 or 7.3, the term of this Agreement shall expire at such time as neither Party shall have any further obligations to pay royalties on the sale of Licensed Products. 7.2. Breach. Failure by a Party to comply with any of its material obligations contained in this Agreement shall entitle the other Party to give to the Party in default notice specifying the nature of the default and requiring it to cure such default. If such default is not cured within 30 days after the receipt of such notice (or 90 days in event such breach cannot be reasonably expected to be cured within 30 days, and the defaulting Party gives notice to the other Party of its inability to cure such default within a 30 day period and the defaulting Party thereafter uses reasonable efforts to cure such default as soon as practicable), the notifying Party shall be entitled, without prejudice to any of its other rights under this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate the rights and licenses of the defaulting Party under Agreement by giving notice to that effect to the defaulting Party. The right of either Party to terminate the rights and licenses granted to the other Party under this Agreements as hereinabove provided, shall not be affected in any way by its waiver or failure to take action with respect to any previous default. 7.3. Insolvency or Bankruptcy. Either Party may, in addition to any other remedies available to it by law or in equity, terminate the rights and licenses granted to the Other Party under this Agreement by written notice to the other Party in the event (i) the other Party shall have become insolvent or bankrupt, or shall have made an assignment for the benefit of its creditors, or (ii) there shall have been appointed a trustee or receiver of the other Party or for all or a substantial part of its property, or (iii) any case or proceeding shall have been commenced or some other action taken by or against the other Party in bankruptcy or seeking reorganization, liquidation, dissolution, winding-up, arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization or other similar act or law of any jurisdiction now or hereafter in effect or there shall have been issued a warrant of attachment, execution, distraint or similar process against any substantial part of the property of the other Party, and any such event or action shall have continued for 60 days undismissed, unbounded and undischarged; provided, however, that no such right to terminate shall pertain solely by virtue of a voluntary reorganization for the purpose of solvent amalgamation or reconstruction. 7.4. Effect of Termination. (a) Upon termination of this Agreement for any reason, nothing herein shall be construed to release either Party from any obligation that matured prior to the effective date of such termination. (b) The termination pursuant to Sections 7.2 or 7.3 of the rights and licenses granted to a Party under this Agreement shall not effect the rights and licenses -16- 21 of the other Party under this Agreement, provided such other Party continues to comply with its obligations hereunder.

Such other Party shall have the right to utilize and allow others to utilize all such materials, documents and records in connection with the development, regulatory approval, manufacture and sale of its Licensed Products and the terminated Party shall provide such other Party with reasonable cooperation, including without limitation, providing such other Party with a letter authorizing such other Party to cross reference the terminated Party's files with the FDA or other regulatory body. (d) The provisions of Sections 2.2(i) (License to CTI), 4 (Patents and Technology), 5 (Confidential Information), 8.11 (Modex Indemnification), 8.12 (CTI Indemnification), 8.13 (Liability Insurance) and 14 (Resolution of Disputes) shall survive termination of this Agreement or termination of any Party's rights and licenses for any reason.

                 CTI - INDIVIDUAL STOCKHOLDERS OPTION AGREEMENT


         This Agreement (the "Agreement"), is made as of this 10th day of July,
1996 by and among CytoTherapeutics, Inc., a Delaware corporation ("CTI") and
each of those individuals listed as Exhibit A (the "Individual Stockholders").

         WHEREAS, each of CTI and the Individual Stockholders owns that number
of shares of Common Stock ("Common Stock") of Modex Therapeutiques, S.A.
("Modex") set forth next to its or his name on Exhibit A acquired on foundation
of Modex; and

         WHEREAS, simultaneously herewith CTI has invested SFr 1.2 million to
subscribe for certain additional shares of Common Stock, loaned to Modex an
additional SFr 1.2 million pursuant to a Convertible Loan Agreement dated as of
the same date as this Agreement and agreed, under such Agreement, to loan Modex
an additional SFr 2.4 million on the second anniversary of this Agreement (the
"Second Anniversary") if certain conditions are met; and

         WHEREAS, simultaneously herewith each of the Individual Stockholders,
with the possible exception of Shimon Efrat, has entered into a Consulting
Agreement of even date herewith (each a "Consulting Agreement") with Modex; and

         WHEREAS, it was a condition to CTI making such investments in Modex
simultaneously herewith that the Individual Stockholders enter into this
Agreement; and

         WHEREAS, CTI wishes to arrange for an option to acquire the shares of
Common Stock held by the Individual Stockholders, and the Individual
Stockholders wish to grant to CTI such an option, on the terms and conditions
contained herein; and

         WHEREAS, the Individual Stockholders wish to obtain an option to
require CTI to purchase the shares of Common Stock held by the Individual
Stockholders and CTI is willing to grant such an option, under the terms and
conditions contained herein;

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained and other valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, CTI and the Individual Stockholders hereby agree as
follows:


   2
         1.  Restrictions on Transfer.

         (a) Individual Stockholders Shares. None of the shares of Common Stock
acquired by any Individual Stockholder on the formation of Modex (collectively,
the "Individual Stockholders Shares") may be sold, exchanged, signed,
transferred, pledged, hypothecated or otherwise encumbered or disposed of, at
any time prior to the expiration of this Agreement except pursuant to the
exercise by such Individual Stockholder of the Individual Stockholders Exchange
Option, or the exercise by CTI of the CTI Exchange Option (in each case, as
defined below).

         (b) Certificates to be Held by Notary. The Individual Stockholders
Shares shall be held by a Notary acceptable to CTI and the Individual
Stockholders under the terms of an Escrow Agreement acceptable to the Notary,
CTI and the Individual Stockholders until the earlier of the termination of this
Agreement or such time as such Individual Stockholders Shares shall have been
exchanged in accordance with the provisions hereof. Any new, additional or
different securities which any Individual Stockholder may be entitled to receive
by virtue of any stock dividend, stock split, reverse stock split,
recapitalization, reorganization, merger, consolidation, split-up or other
similar change shall be held by such Notary and subject to the same
restrictions, terms and conditions as set forth herein. Each Individual
Stockholder shall possess all rights of ownership of his Individual Stockholders
Shares, including the right to receive or reinvest dividends with respect to
such Individual Stockholders Shares and to vote such Individual Stockholder
Shares (subject to the terms of any other agreements applicable thereto) and to
receive any and all payments made with respect to such Individual Stockholders
Shares, except that such Individual Stockholder shall not be entitled to
possession of his Individual Stockholders Shares until the restrictions provided
for in this Agreement have lapsed.

         2.  CTI Option to Acquire Individual Stockholders Shares.

         (a) CTI Exchange Option. CTI shall have the option (the "CTI Exchange
Option"), at any time and from time to time, to purchase any or all of any
Individual Stockholder's Individual Stockholders Shares by exchanging 13.145
shares (subject to adjustment as provided in Section 4 below) of CTI Common
Stock, $.01 par value ("CTI Common Stock") for each share of such Individual
Stockholders Shares so acquired.

         (b) Efrat Purchase Option. CTI Repurchase of Dr. Efrat's Subject
Shares. In the event Dr. Efrat has entered into a Consulting Agreement with
Modex dated on or about the date hereof, the provisions of subsection (c) of
this Section 2 shall apply and the provisions of this sub-section (b) shall be
of no further force or effect. In the event Dr. Efrat has not entered into a
Consulting Agreement with Modex dated on or about the date hereof, CTI shall
have the right at any time within two (2) years from date hereof to purchase
from Dr. Efrat all of Dr. Efrat's Subject Shares (as defined below) for 10 SF
per share (the "Efrat Repurchase Right")


                                       -2-
   3
         (c) CTI Repurchase of Subject Shares. In the event that, within two (2)
years of the date hereof, any Individual Stockholder ceases to serve as a
consultant to Modex as a result of the termination of such Individual
Stockholder's consulting relationship under the Consulting Agreement by Modex
for "Cause" (as defined in the Consulting Agreement) or by the Individual
Stockholder without "Good Reason" (as defined in the Consulting Agreement), CTI
shall thereafter have the right (the "Repurchase Right") to purchase from such
Individual Stockholder all of such Individual Stockholder's shares of Modex
stock identified on Schedule C as "Subject Shares" (the "Subject Shares") for 10
SF per share.

         (d) Call Notice. CTI shall notify any Individual Stockholder of any
exercise of the CTI Exchange Option in writing (the "Call Notice") and shall
deliver to the Notary for delivery to such Individual Stockholder the aggregate
number of shares of CTI Common Stock required hereunder within 30 days of the
date of such Call Notice (the "Call Notice Date"). Upon such delivery, the
Notary shall promptly release to CTI the acquired Individual Stockholders Shares
and deliver to such Individual Stockholder such shares of CTI Common Stock.

         (e) Repurchase Notice. CTI shall notify any Individual Stockholder of
any exercise of the Repurchase Right or the Efrat Repurchase Right, as the case
may be, in writing (the "Repurchase Notice"), which notice shall set forth the
number of Subject Shares to be purchased by CTI and the time, date and location
in Lausanne, Switzerland (or other location mutually agreeable to CTI and the
Individual Stockholder) of the closing of the purchase by CTI of the Subject
Shares. At such closing, the Individual Stockholder shall deliver to CTI the
stock certificates evidencing the Subject Shares to be purchased duly endorsed
in blank and CTI shall deliver to the Individual Stockholder the aggregate
purchase price for the Subject Shares to be purchased by CTI by check or wire
transfer.

         3. Individual Stockholders' Option to Require CTI to Acquire Individual
Stockholders Shares.

         (a) Each Individual Stockholder's Exchange Option. Each Individual
Stockholder shall have the option, at any time and from time to time (the
"Individual Stockholders Exchange Option"), to require CTI to acquire any or all
of such Individual Stockholder's Individual Stockholders Shares in exchange for
13.145 shares (subject to adjustment as provided in Section 4 below) of CTI
Common Stock for each share of such Individual Stockholders Shares so acquired.

         (b) Put Notice. Any Individual Stockholder wishing to exercise his
Individual Stockholders Exchange Option shall notify CTI of such exercise in
writing (the "Put Notice") and shall instruct the Notary to deliver to CTI the
Individual Stockholders Shares to be acquired by CTI upon delivery by CTI to the
Notary of the shares of CTI Common Stock to be delivered in exchange for such
Individual Stockholders Shares. CTI shall deliver to the Notary for delivery to
such Individual Stockholder the aggregate number of shares of CTI Common Stock
required hereunder within 30 days of the date of such Put Notice (the "Put

                                       -3-
   4
Notice Date"). Upon such delivery, the Notary shall promptly release to CTI the
acquired Individual Stockholders Shares and deliver to such Individual
Stockholder such shares of CTI Common Stock.

         4.  Adjustments; Fractional Shares.

         The number of shares of CTI Common Stock to be exchanged for each share
of Individual Stockholders Shares hereunder shall be appropriately adjusted to
reflect any stock dividend, stock split, reverse stock split, recapitalization,
reorganization, merger, consolidation, split-up or other similar change
(occurring at any time prior to the release and delivery of any such shares as
provided for in Section 2 or 3 hereunder) with respect to or otherwise affecting
the Individual Stockholders Shares or the CTI Common Stock or both. In lieu of
the issuance of any fractional shares of CTI Common Stock, CTI shall pay to
Individual Stockholder in cash an amount equal to the value of any fractional
share, determined on the basis of the closing price for the shares of CTI Common
Stock on the Call Notice Date or the Put Notice Date, as the case may be.

         5. Representations, Warranties and Agreements.

         Each Individual Stockholder hereby acknowledges, represents and
warrants to, and agrees with, CTI as follows:

                  (a) Individual Stockholder understands that the shares of CTI
Common Stock that Individual Stockholder may receive hereunder have not been
registered under the U.S. Securities Act of 1933, as amended (the "Securities
Act"), or any state or foreign securities laws and are expected to be issued in
reliance upon Regulation S promulgated under the Securities Act;

                  (b) Individual Stockholder has been supplied with or has had
sufficient access to all other information, including financial statements and
other financial information of CTI, to which a reasonable investor would attach
significance in making investment decisions, and has had the opportunity to ask
questions and receive answers from knowledgeable individuals concerning CTI, so
that, as a reasonable investor, Individual Stockholder has been able to make his
own independent decision to put himself in a position wherein he may be
acquiring such CTI Common Stock;

                  (c) Individual Stockholder is not a U.S. Person and is not
entering into this Agreement in order to acquire any CTI Common Stock for the
account or benefit of a U.S. Person. For purposes of this Agreement, "U.S.
Person" shall have the meaning set forth in Rule 903(o) of Regulation S under
the Securities Act;

                  (d) Individual Stockholder agrees not to offer or sell such
CTI Common Stock in the United States or to or for the account or benefit of a
U.S. Person or citizen of the United States prior to the expiration of the forty
(40) day period commencing on the date

                                       -4-
   5
Individual Stockholder receives any such CTI Common Stock hereunder (the
"Restricted Period"). Individual Stockholder acknowledges that CTI will not
authorize any transfer or sale of such CTI Common Stock in the United States or
to a U.S. Person or citizen of the United States other than in accordance with
Regulation S and U.S. federal securities laws. Prior to any sale or transfer of
such CTI Common Stock during the Restricted Period or in the United States or to
a U.S. Person, CTI may require the written opinion of United States legal
counsel addressed to CTI, as to whether such transfer or sale is in compliance
with the Securities Act and the rules and regulations applicable thereunder,
including Regulation S, and may require certification of the transferor and the
transferee of such CTI Common Stock as to such compliance; and

                  (e) Should Regulation S not be available with regard to any
exercise of the Individual Stockholders Exchange Option or the CTI Exchange
Option (for example, because Individual Stockholder is or has become a U.S.
Person), Individual Stockholder and CTI acknowledge and agree that the Shares of
CTI Common Stock to be issued in exchange for Individual Stockholder's
Individual Stockholders Shares hereunder shall be issued in a private placement
exempt from the registration requirements of the Securities Act pursuant to
Section 4.2 of such Act and that any shares of CTI Common Stock so issued shall
be subject to the restrictions generally applicable to such securities in
transactions which qualify for such exemption.

         6. Legend.

         Each certificate representing the CTI Common Stock issued hereunder
pursuant to Regulation S shall bear a restrictive legend in substantially the
form set forth below:

                  "The securities represented by this certificate have not been
                  registered under the U.S. Securities Act of 1933, as amended
                  (the "Act"), and have been issued pursuant to an exemption
                  from registration pursuant to Regulation S under the Act.
                  These shares cannot be transferred, offered, or sold in the
                  United States or to a U.S. Person (as that term is defined in
                  Regulation S) unless such shares are registered under the Act
                  or an exemption from registration is available. The offer or
                  sale of these shares to a U.S. Person (as that term is defined
                  in Regulation S) or in the United States is subject to certain
                  restrictions as set forth in that certain Option Agreement
                  dated July 10, 1996 between CTI and the original holders of
                  these shares."

Shares of CTI Common Stock, if any, issued in a private placement pursuant to
Section 5(e) shall also bear an appropriate restrictive legend.

         7. Shares of CTI Common Stock to be Received From Modex Under each
Individual Stockholder's Consulting Agreement. Each Individual Stockholder
agrees that any shares of CTI Common Stock received by such Individual
Stockholder from Modex under such

                                       -5-
   6
Individual Stockholder's Consulting Agreement with Modex dated as of the same
date as this Agreement shall be subject to the same restrictions provided for in
Sections 5 and 6 hereof.

         8. Termination.

         (a) This Agreement shall terminate on the earlier to occur of the tenth
anniversary of this Agreement or the closing of an underwritten public offering
of the Common Stock.

         9. Notices. All notices and other communications hereunder shall be in

Individual Stockholder at their respective addresses set forth on Exhibit A, or
in any case to such other address as the addressee shall have furnished to the
other parties hereto in the manner prescribed by this Section .

         10. Specific Performance. The rights of the parties under this
Agreement are unique and, accordingly, the parties shall, in addition to such
other remedies as may be available to any of them at law, have the right to
enforce their rights hereunder by actions for specific performance to the extent
permitted by law.

         11. Entire Agreement. This Agreement constitutes the entire agreement
among the parties with respect to the subject matter hereof and supersedes and
cancels all prior agreements and understandings between them or any of them as
to such subject matter.

         12. Waivers and Further Agreements. Neither this Agreement nor any
provision hereof may be waived, modified, terminated or amended except by a
written agreement signed by CTI and all Individual Stockholders. Any waiver by
any party of a breach of any provision of this Agreement shall not operate or be
construed as a waiver of any subsequent breach of that provision or of any other
provision hereof. Each of the parties hereto agrees to execute all such further
instruments and documents and to take all such further action as any other party
may reasonably require in order to effectuate the terms and purposes of this
Agreement.

         13. Assignment; Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
heirs, executors, legal representatives, successors and permitted assigns.
Without limiting the generality of the foregoing sentence, more particularly,
while this Agreement does not contemplate the transfer of any Individual
Stockholders Shares except upon an exercise by CTI of the CTI Exchange Option or
an exercise by an Individual Stockholder of the Individual Stockholders Exchange
Option, should any such transfer occur by agreement of the parties or by
operation of law, the transferee of such shares shall, to the maximum extent
permitted by law, be bound by the terms of this Agreement and any applicable
provisions of the Articles of Incorporation of Modex.


                                       -6-

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

         15. Section Headings. The headings contained in this Agreement are for
reference purposes only and shall not in any way affect the meaning or
interpretation of this Agreement.

         16. Choice of Law. This Agreement shall be governed and construed

         WHEREAS, it was a mutual condition to CTI and Valoria making such
investments in Modex simultaneously herewith that each enter into this
Agreement; and

         WHEREAS, CTI wishes to arrange for an option to acquire the shares of
Common Stock held by Valoria and the Valoria Loans, and Valoria wishes to grant
to CTI such an option, on the terms and conditions contained herein; and

         WHEREAS, Valoria wishes to obtain an option to require CTI to purchase
the shares of Common Stock held by Valoria and the Valoria Loans and CTI is
willing to grant such an option, under the terms and conditions contained
herein;

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained and other valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, CTI and Valoria hereby agree as follows:


   2
         1.  Restrictions on Transfer.

         (a) Valoria Shares and Notes. None of the shares of Common Stock
acquired by Valoria on the formation of Modex or the shares of Common Stock to
be acquired by Valoria upon conversion of the Valoria Loans (collectively, the
"Valoria Shares") or the Valoria Loans (together with the Valoria Shares, the
"Valoria Securities") or any interest therein may be sold, exchanged, signed,
transferred, pledged, hypothecated or otherwise encumbered or disposed of, at
any time prior to the expiration of this Agreement except pursuant to the
exercise by Valoria of the Valoria Exchange Option, or the exercise by CTI of
the CTI Exchange Option (in each case, as defined below).

         (b) Certificates to be Held by Notary. The Valoria Shares shall be held
by a notary (the "Notary") acceptable to CTI and Valoria under the terms of an
Escrow Agreement acceptable to CTI, Valoria and the Notary until the earlier of
the termination of this Agreement or such time as such Valoria Shares shall have
been exchanged in accordance with the provisions hereof. Any new, additional or
different securities which Valoria may be entitled to receive by virtue of the
conversion of the Valoria Loans or any stock dividend, stock split, reverse
stock split, recapitalization, reorganization, merger, consolidation, split-up
or other similar change shall be held by such Notary and subject to the same
restrictions, terms and conditions as set forth herein. Valoria shall possess
all incidents of ownership of the Valoria Shares, including the right to receive
or reinvest dividends with respect to the Valoria Shares and to vote such
Valoria Shares (subject to the terms of any other agreements applicable
thereto), except that Valoria shall not be entitled to possession of the Valoria
Shares until the restrictions provided for in this Agreement have lapsed.

         2.  Exchange Option for Valoria Securities.

         (a) CTI Exchange Option. CTI shall have the option (the "CTI Exchange
Option") to purchase the Valoria Securities on the following terms and
conditions:

                  (i)      During First Two Years. At any time prior to the
                           Second Anniversary, CTI may purchase all but not less
                           than all of the Valoria Securities for the greater of
                           (i) Sfr 3.6 million or (ii) Sfr 2.4 million plus
                           simple interest thereon at the rate of 30% per year
                           from the Closing Date until the Option Closing Date
                           (as defined below), accruing daily, such
                           consideration to be payable in cash or, at CTI's
                           option, in whole or in part in shares of Common Stock
                           of CTI, par value $.01 per share ("CTI Common
                           Stock"), valued as described below.

                  (ii)     After First Two Years. At any time on or after the
                           Second Anniversary, CTI may purchase all but not less
                           than all of the Valoria Securities at a price equal
                           to 110% of the As Converted Value of the Valoria
                           Securities as of the Option Notice Date (as such
                           terms are defined below), such consideration to be
                           payable in cash or, at CTI's

                                       -2-
   3
                           option, in whole or in part, in shares of CTI Common
                           Stock, valued as described below.

         (b) CTI Option Notice. CTI shall notify Valoria of its exercise of the
CTI Exchange Option in writing (the "CTI Option Notice") and shall indicate in
such notice whether CTI intends to purchase such shares with cash or with CTI
Common Stock or with cash and CTI Common Stock.

         If the CTI Exchange Option is being exercised pursuant to Section 
2(a)(i), CTI shall pay to Valoria (in cash or CTI Common Stock) the aggregate
purchase price as indicated in Section 2(a)(i) within 30 days of the date of the
CTI Option Notice (the "Notice Date") against simultaneous release to CTI by the
Notary of all escrowed Valoria Shares and assignment to CTI of all of Valoria's
interest (if any) in the Valoria Loans.

         If the CTI Exchange Option is being exercised pursuant to Section 
2(a)(ii), CTI and Valoria shall have 30 days from Notice Date to agree upon the
fair market value of the Valoria Securities determined on the basis of the fair
market value of the shares of Modex Common Stock that would be held by Valoria
assuming the conversion of all outstanding Valoria Loans into shares of Modex
Common Stock and the similar conversion of all outstanding CTI Loans into shares
of such Common Stock (the "As Converted Value"). If, by the end of such
thirty-day period, no agreement as to the As Converted Value has been reached,
the As Converted Value shall be determined by an appraisal. All appraisals shall
be undertaken by an independent investment banking firm (initially agreed to be
Hambrecht & Quist) acceptable to both CTI and Valoria (the "Appraiser")
commencing on the 31st day after the Notice Date. On such date, Valoria and CTI
shall each submit to the Appraiser a final estimate of the As Converted Value,
and, within 60 days of such submission, the Appraiser shall determine which of
such two estimates is closer to the As Converted Value as determined by the
Appraiser and such closer estimate shall be deemed to be the As Converted Value.
Within 30 days after the determination of the As Converted Value specified
above, CTI shall pay Valoria the aggregate purchase price (in cash or CTI Common
Stock) as indicated in Section 2(a)(ii) (the date of such payment pursuant to
this sentence or pursuant to the last sentence in the previous paragraph being
referred to herein as the "Option Closing Date") against simultaneous release to
CTI by the Notary of all escrowed Valoria Shares and assignment to CTI of all of
Valoria's interest (if any) in the Valoria Loans. The party whose final estimate
is not selected as the As Converted Value shall pay the cost of the appraisal.

         (c) Valoria Exchange Option. If at any time on or after the Second
Anniversary and prior to the tenth anniversary of this Agreement (the "Tenth
Anniversary"), no Public Market exists for the Founder's Shares, Valoria shall
have the option (the "Valoria Exchange Option") to require CTI to purchase all
but not less than all of the Valoria Securities at a price equal to 90% of the
As Converted Value as of the Put Notice Date (as defined below), such
consideration to be payable in cash or, at CTI's option, in whole or in part in
shares of CTI Common Stock, valued as described below. A "Public Market" for the
Founder's

                                       -3-
   4
Shares will exist if and only if the shares of CTI and Valoria Common Stock are
listed for trading on an internationally recognized securities market.

         (d) Valoria Put Notice. Valoria shall notify CTI of its exercise of the
Valoria Exchange Option in writing (the "Put Notice"). CTI shall indicate in a
notice delivered to Valoria within 30 days of the date of such Put Notice (the
"Notice Date") whether CTI intends to purchase such shares with cash or with CTI
Common Stock or with cash and CTI Common Stock. CTI and Valoria shall have 30
days from the Notice Date to agree upon the As Converted Value. If, by the end
of such thirty-day period, no agreement as to the As Converted Value has been
reached, the As Converted Value shall be determined by an appraisal, as provided
in Section 2(b) above, the cost of which shall be paid as provided therein.
Within 30 days after the determination of the As Converted Value, CTI shall pay
to Valoria the aggregate purchase price (in cash or CTI Common Stock) indicated
in Section 4(c) (the date of such payment being referred to herein as the "Put
Closing Date").

         (e) Valuation of CTI Common Stock. For purposes of this Section 2, the
fair market value of CTI Common Stock shall be the average of the closing prices
(as described below) for shares of the CTI Common Stock for each of the 10
consecutive trading days before and each of the 10 consecutive trading days
after the Put Notice Date or the Option Notice Date, as the case may be. The
closing price for such shares for each day shall be the average of the reported
closing bid and asked prices on the principal United States securities exchange
registered under the Securities Exchange Act of 1934, as amended, on which such
shares are listed or admitted to trading, or if they are not listed or admitted
to trading on any such exchange, the average of the quoted closing bid and asked
prices as reported on the Nasdaq Stock Market, or any comparable system, or if
such shares are not quoted on the Nasdaq Stock Market, or any comparable system,
the average of the closing bid and asked prices as furnished by any market maker
in such shares who is a member of the National Association of Securities
Dealers, Inc.

         (f) Price Protection for Valoria. In the event that CTI sells,
transfers, assigns or otherwise disposes any Valoria Securities acquired by CTI
from Valoria pursuant to Section 2(a) (or any shares of Modex Common Stock
issuable on conversion of any such securities) within 180 days of the Option
Closing Date and the price CTI receives for such securities (the "Third Party
Price") is in excess of the price received for such Securities by Valoria from
CTI on the Option Closing Date (the "Valoria Price"), then CTI shall pay to
Valoria the difference between the Third Party Price and the Valoria Price with
respect to all such securities so sold, transferred, assigned or otherwise
disposed of by CTI, such consideration to be payable in cash or, at CTI's
option, in whole or in part in shares of CTI Common Stock, valued at the Option
Closing Date as described above.

         3. Representations, Warranties and Agreements.

         Valoria hereby acknowledges, represents and warrants to, and agrees
with, CTI as follows:

                                       -4-
   5
                  (a) Valoria understands that the shares of CTI Common Stock
that Valoria may receive hereunder have not been registered under the U.S.
Securities Act of 1933, as amended (the "Securities Act"), or any state or
foreign securities laws and are expected to be issued in reliance upon
Regulation S promulgated under the Securities Act;

                  (b) Valoria has been supplied with or has had sufficient
access to all other information, including financial statements and other
financial information of CTI, to which a reasonable investor would attach
significance in making investment decisions, and has had the opportunity to ask
questions and receive answers from knowledgeable individuals concerning CTI, so
that, as a reasonable investor, Valoria has been able to make his own
independent decision to put himself in a position wherein he may be acquiring
such CTI Common Stock;

                  (c) Valoria is not a U.S. Person and is not entering into this
Agreement in order to acquire any CTI Common Stock for the account or benefit of
a U.S. Person. For purposes of this Agreement, "U.S. Person" shall have the
meaning set forth in Rule 903(o) of Regulation S under the Securities Act;

                  (d) Valoria agrees not to offer or sell such CTI Common Stock
in the United States or to or for the account or benefit of a U.S. Person or
citizen of the United States prior to the expiration of the forty (40) day
period commencing on the date Valoria receives any such CTI Common Stock
hereunder (the "Restricted Period"). Valoria acknowledges that CTI will not
authorize any transfer or sale of such CTI Common Stock in the United States or
to a U.S. Person or citizen of the United States other than in accordance with
Regulation S and U.S. federal securities laws. Prior to any sale or transfer of
such CTI Common Stock during the Restricted Period or in the United States or to
a U.S. Person, CTI may require the written opinion of United States legal
counsel addressed to CTI, as to whether such transfer or sale is in compliance
with the Securities Act and the rules and regulations applicable thereunder,
including Regulation S, and may require certification of the transferor and the
transferee of such CTI Common Stock as to such compliance; and

                  (e) Should Regulation S not be available with regard to any
exercise of the Valoria Exchange Option or the CTI Exchange Option (for example,
because Valoria is or has become a U.S. Person), Valoria and CTI acknowledge and
agree that the Shares of CTI Common Stock to be issued in exchange for Valoria's
Valoria Securities hereunder shall be issued in a private placement exempt from
the registration requirements of the Securities Act pursuant to Section 4.2 of
such Act and that any shares of CTI Common Stock so issued shall be subject to
the restrictions generally applicable to such securities in transactions which
qualify for such exemption.

         4.  Legend.

         Each certificate representing the CTI Common Stock issued hereunder
pursuant to Regulation S shall bear a restrictive legend in substantially the
form set forth below:

                                      -5-
   6
                  "The securities represented by this certificate have not been
                  registered under the U.S. Securities Act of 1933, as amended
                  (the "Act"), and have been issued pursuant to an exemption
                  from registration pursuant to Regulation S under the Act.
                  These shares cannot be transferred, offered, or sold in the
                  United States or to a U.S. Person (as that term is defined in
                  Regulation S) unless such shares are registered under the Act
                  or an exemption from registration is available. The offer or
                  sale of these shares to a U.S. Person (as that term is defined
                  in Regulation S) or in the United States is subject to certain
                  restrictions as set forth in that certain Option Agreement
                  dated July __, 1996 between CTI and the original holders of
                  these shares."

Shares of CTI Common Stock, if any, issued in a private placement pursuant to
Section 3(e) shall also bear an appropriate restrictive legend.

         5.  Termination.

         (a) This Agreement shall terminate on the earlier to occur of the tenth
anniversary of this Agreement or the closing of an underwritten public offering
of Modex Common Stock.

         6. Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been received when delivered to CTI and
Valoria at their respective addresses set forth on Exhibit A, or in any case to
such other address as the addressee shall have furnished to the other party
hereto in the manner prescribed by this Section.

         7. Specific Performance. The rights of the parties under this Agreement
are unique and, accordingly, each party shall, in addition to such other
remedies as may be available to it at law, have the right to enforce its rights
hereunder by actions for specific performance to the extent permitted by law.

         8. Entire Agreement. This Agreement constitutes the entire agreement
among the parties with respect to the subject matter hereof and supersedes and
cancels all prior agreements and understandings between them as to such subject
matter.

         9. Waivers and Further Agreements. Neither this Agreement nor any
provision hereof may be waived, modified, terminated or amended except by a
written agreement signed by CTI and Valoria. Any waiver by either party of a
breach of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent breach of that provision or of any other provision
hereof. Each of the parties hereto agrees to execute all such further
instruments and documents and to take all such further action as any other party
may reasonably require in order to effectuate the terms and purposes of this
Agreement.

         10. Assignment; Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
heirs, executors, legal representatives, successors and permitted assigns.
Without limiting the general application of

                                       -6-
   7
the foregoing sentence, more particularly, while this Agreement does not
contemplate the transfer of any Valoria Securities or any interest therein
except through the exercise by CTI of the CTI Exchange Option or the exercise by
Valoria of the Valoria Exchange Option, should any such other transfer occur by
agreement of the parties or by operation of law, the transferee shall, to the
maximum extent permitted by law, be bound by the terms of this Agreement and any
applicable provisions of the Articles of Incorporation of Modex.

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

         12. Section Headings. The headings contained in this Agreement are for
reference purposes only and shall not in any way affect the meaning or
interpretation of this Agreement.

         13. Choice of Law. This Agreement shall be governed and construed
according to the internal laws of Switzerland.

         14. Dispute Resolution. All disputes, differences, controversies or
claims arising in connection with, or questions occurring under, this Agreement
shall be settled as provided in Exhibit B, except for the determination of As
Converted Value, which shall be conclusively determined as provided for in
Section 2.

10 EXHIBIT B Arbitration Any and all disputes, controversies or claims arising out of, involving or relating to the existence, validity, performance, amendment, breach or termination of this Agreement shall be referred to, settled and finally resolved exclusively under the rules of arbitration of La Chambre de Commerce et d'Industrie de Geneve ("CCIG") by an arbitral tribunal appointed as set forth herein in accordance with said rules. To the extent not prohibited under applicable law, the arbitral tribunal's decision shall be final and binding on the parties and, to the extent not prohibited under applicable law, the parties hereby exclude any right of appeal to any court on the merits of any dispute. Subject to the provisions of the last paragraph, each party shall nominate one arbitrator. If a party fails to nominate an arbitrator within thirty (30) days from the date when the claimant's request for arbitration has been communicated to the other party, such appointment shall be made by the rules of CCIG. The two arbitrators so appointed shall agree upon the third arbitrator who shall act as Chair of the arbitral tribunal. If said two arbitrators fail to nominate a Chair within thirty (30) days from the latter of the two appointments, the Chair shall be selected by the rules of CCIG. Such appointment shall be final and binding upon the parties. The place of arbitration shall be Geneva, Switzerland. The language to be used in the arbitral proceeding shall be English. The proceedings shall be governed by the provisions of Chapter 12 of the Swiss Federal Act on International Private Law of December 18, 1987 relating to international arbitration and the rules of arbitration of CCIG. This Agreement and the arbitral award shall be governed by the law of Switzerland. The award shall be in writing and shall include the arbitral tribunal's decision as to the costs of the arbitration and reasonable legal fees. The award may grant any relief appropriate under the applicable law, including without limitation declaratory relief and/or specific performance. The award will be notified to the parties by the Arbitral Tribunal. In the event that disputes arise between two parties under this Agreement and any other agreement, document or instrument executed in connection with the transactions contemplated hereby, such disputes shall be resolved in a consolidated arbitral proceeding by the three arbitrators appointed in accordance with the provisions above. Notwithstanding the foregoing, in the event that disputes arise between more than two parties under this Agreement or under this Agreement and any other agreement, document or instrument -10- 11 executed in connection with the transactions contemplated hereby, such disputes shall be resolved in a consolidated arbitral proceeding by a single arbitrator appointed in accordance with the rules of CCIG. -11-

           CAUTIONARY FACTORS RELEVANT TO FORWARD-LOOKING INFORMATION

        CytoTherapeutics, Inc. (the "Company") wishes to caution readers that
the following important factors, among others, in some cases have affected and
in the future could affect the Company's results and could cause actual results
and needs of the Company to vary materially from forward-looking statements
made in this Quarterly Report by the Company on the basis of management's
current expectations. The business in which the Company is engaged is rapidly
changing, extremely competitive and involves a high degree of risk, and
accuracy with respect to forward-looking projections is difficult.

EARLY STAGE DEVELOPMENT; HISTORY OF OPERATING LOSSES - Substantially all of the
Company's revenues to date have been derived, and for the foreseeable future
substantially all of the Company's revenues will be derived, from collaborative
agreements, research grants and income earned on invested funds. The Company
will incur substantial operating losses in the future as the Company conducts
its research, development, clinical trial and manufacturing activities. There 
can be no assurance that the Company will achieve revenues from product sales
or become profitable.

FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING - The development of
the Company's products will require the commitment of substantial resources to
conduct the time-consuming research, preclinical development and clinical trials
that are necessary for regulatory approvals and to establish production and
marketing capabilities if such approvals are obtained. The Company will need to
raise substantial additional funds to continue its product development efforts
and intends to seek such additional funds through partnership, collaborative or
other arrangements with corporate sponsors, public or private equity or debt
financings, or from other sources. Future cash requirements may vary from
projections based on changes in the Company's research and development programs,
progress in preclinical and clinical testing, the Company's ability to enter
into, and perform successfully under, collaborative agreements, competitive and
technological advances, the need to obtain proprietary rights owned by third
parties, facilities requirements, regulatory approvals and other factors. Lack
of necessary funds may require the Company to delay, reduce or eliminate some or
all of its research and product development programs or to license its potential
products or technologies to third parties. No assurance can be given that
funding will be available when needed, if at all, or on terms acceptable to the
Company.

UNCERTAINTIES OF CLINICAL DEVELOPMENT AND NEW MODE OF THERAPY - None of the
Company's proposed products has been approved for commercial sale or entered
Phase II or III clinical trials. Even if the Company's proposed products appear
to be promising at an early stage of research or development such products may
later prove to be ineffective, have adverse side effects, fail to receive
necessary regulatory approvals, fail to gain market acceptance, be difficult 
or uneconomical to manufacture or market on a commercial scale, be adversely 
affected by government price 

   2
controls or limitations on reimbursement, be precluded from commercialization by
proprietary rights of third parties or be subject to significant competition
from other products. There can be no assurance that the Company will be able to
demonstrate, as required, that its implants, on a consistent basis and on a
commercial scale, among other things: (i) successfully isolate transplanted
cells from the recipient's immune system; (ii) remain biocompatible with the
tissue into which they are implanted, including, for certain implants, brain
tissue; (iii) adequately maintain the viability of cells contained within the
membrane; (iv) safely permit the therapeutic substances produced by the cells
within the membrane to pass through the membrane unto the patient in controlled 
doses for extended periods; and (v) are sufficiently durable for the intended 
indication.

DEPENDENCE ON OUTSIDE PARTIES--The Company's strategy for the research,
development, commercialization and marketing of its products contemplates that
the Company will enter into various arrangements with corporate sponsors,
pharmaceutical companies, universities, research groups and others. There is no
assurance that the Company will be able to enter into any additional
arrangements on terms acceptable to the Company, or successfully perform its
obligations under its existing or any additional arrangements. If any of the
Company's collaborators fails to perform its obligations in a timely manner or
terminate their agreement with the Company, the development or
commercialization of the Company's product candidate or research program under
such collaborative agreement may be adversely affected.

NEED FOR AND UNCERTAINTY OF OBTAINING PATENT PROTECTION--Patent protection for
products such as those the Company proposes to develop is highly uncertain and
involves complex factual and evolving legal questions. No assurance can be
given that any patents issued or licensed to the Company will not be
challenged, invalidated or circumvented, or that the rights granted under such
patents will provide competitive advantages to the Company.

EXISTENCE OF THIRD PARTY PATENTS AND PROPRIETARY RIGHTS; NEED TO OBTAIN
LICENSES--There are pending patent applications or issued patents held by others
relating to the Company's proposed products or the technology to be utilized by
the Company in the development of its proposed products. If such patents or
other patents are determined by the Company or a court to be valid and
infringed, the Company may be required to alter its products or processes, pay
licensing fees or royalties or cease certain activities. In particular, the
Company is aware of one issued patent claiming certain methods for treating
defective, diseased or damaged cells in the mammalian CNS by grafting
genetically modified donor cells from the same mammalian species. In addition,
each of the neurotrophic factors which the Company is currently investigating
for use in its proposed products is the subject of one or more claims in patents
or patent applications of third parties, and certain other neurotrophic factors
are the subject of third party patent applications. The Company may also be
required to seek licenses in regard to other cell lines, the techniques used in
creating or obtaining such cell lines, the materials used in the manufacture of
its implants or otherwise. There can be no assurance that the Company will be
able to establish collaborative arrangements or obtain licenses to the

foregoing technology or to other necessary or desirable technology on
acceptable terms, if at all, or that the patents underlying any such licenses
will be valid and enforceable.

GOVERNMENT REGULATION - The Company's research, preclinical development and
clinical trials, as well as the manufacturing and marketing of its potential
products, are subject to extensive regulation by government authorities in the
United States and other countries. The process of obtaining FDA and other
required regulatory approvals is lengthy, expensive and uncertain. There can be
no assurance that the Company or its collaborators will be able to obtain the
necessary approvals to commence or continue clinical testing or to manufacture
or market its potential products in anticipated time frames, if at all. In
addition, the U.S. Public Health Service has published draft "Guidelines on
Infectious Disease Issues: Xenotransplantation," which propose recommendations
to minimize any potential public health risk associated with
xenotransplantation. Xenotransplantation, in this case, is the transplantation
into humans of living cells, tissues or organs from a non-human animal source.
There have also been several legislative proposals to reform the FDA. If such
guidelines and/or proposals are adopted they may result in significant changes
in the regulatory environment the Company faces. These changes could (i) result
in different, more costly or more time consuming approval requirements for the
Company's products, (ii) adversely affect the Company's ability to recruit
subjects for clinical trials, (iii) result in the dilution of FDA resources
available to review the Company's products, or (iv) result in other
unpredictable consequences.

SOURCES OF CELLS AND OTHER MATERIALS - The Company's potential products require
genetically engineered cell lines or living cells harvested from animal or
human sources. There can be no assurance that the Company will successfully
identify or develop sources of the cells required for its potential products and
obtain such cells in quantities sufficient to satisfy the commercial
requirements of its potential products. These supply limitations may apply, in
particular, to primary cells which must be drawn directly from animal or human
sources, such as the bovine adrenal chromaffin cells currently used in the
Company's product for the treatment of pain. As an alternative to primary
cells, the Company is developing products based on the used of genetically
altered cells. Intellectual property rights to important genetic constructs
used in developing such cells, including the constructs used to develop cells
producing neurotrophic factors, are or may be claimed by one or more companies,
which could prevent the Company from using such cells.

MANUFACTURING UNCERTAINTIES - The Company's pilot manufacturing plant, may not
have sufficient capacity to permit the Company to produce all the products for
clinical trials it anticipates developing. In addition, the Company has not
developed the capability to commercially manufacture any of its proposed
products and is unaware of any other company which has manufactured any
membrane-escapulsated cell product on a commercial scale. There can be no
assurance that the Company will be able to develop the capability of
manufacturing any of its proposed products at a cost or in the quantities
necessary to make a commercially viable product, if at all.

COMPETITION - Competitors of the Company are numerous and include major
pharmaceutical and chemical companies, biotechnology companies, universities 
and other research institutions. Currently, several of these competitors market
and sell therapeutic products for the treatment of chronic pain, Parkinson's 
disease and other CNS conditions. In addition, most of the Company's 
competitors have substantially greater capital resources, experiences in 
obtaining


 
                                      -3-
   4
regulatory approvals and, in the case of commercial entities, experience in
manufacturing and marketing pharmaceutical products, than the Company. A number
of other companies are attempting to develop methods of delivering therapeutic
substances within or across the blood brain barrier. There can be no assurance
that the Company's competitors will not succeed in developing technologies and
products that are more effective than those being developed by the Company or
that would render the Company's technology and products obsolete or
non-competitive.

DEPENDENCE ON KEY PERSONNEL - The Company is highly dependent on the principal
members of its management and scientific staff and certain of its outside
consultants. Loss of the services of any of these individuals could have a
material adverse effect on the Company's operations. In addition, the Company's
operations are dependent upon its ability to attract and retain additional
qualified scientific and management personnel. There can be no assurance the
Company will be able to attract and retain such personnel on acceptable terms
given the competition among pharmaceutical, biotechnology and health care
companies, universities and research institutions for experienced personnel.

REIMBURSEMENT AND HEALTH CARE REFORM - In both domestic and foreign markets,
sales of the Company's potential products will depend in part upon the
availability and amounts of reimbursement from third-party health care payor
organizations, including government agencies, private health care insurers and
other health care payors such as health maintenance organizations and
self-insured employee plans. There is considerable pressure to reduce the cost
of therapeutic products. There can be no assurance that reimbursements will be
provided by such payors at all or without substantial delay, or, if such
reimbursement is provided, that the approved reimbursement amounts will provide
sufficient funds to enable the Company to sell its products on a profitable
basis.
