PART I - ITEM 1 - FINANCIAL STATEMENTS


NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
MARCH 31, 1999 AND 1998

NOTE 1.   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 months ended March 31, 1999 are not necessarily indicative of
    the results that may be expected for the entire fiscal year ending December
    31, 1999.

    The balance sheet at December 31, 1998 has been derived from the audited
    financial statements at that date but does not include all of the
    information and footnotes required by generally accepted accounting
    principles for complete financial statements.

    For further information, refer to the audited financial statements and
    footnotes thereto as of December 31, 1998 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.   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 3.   ADOPTION OF NEW ACCOUNTING PRONOUNCEMENT

    As of January 1, 1998, the Company adopted Statement 130, REPORTING
    COMPREHENSIVE INCOME. Statement 130 establishes new rules for reporting and
    display of comprehensive income and its components; however, the adoption of
    this Statement had no impact on the Company's net income or shareholders'
    equity. Statement 130 requires unrealized gains or losses on the Company's
    available-for-sale securities which prior to adoption were reported
    separately in shareholders' equity to be included in other comprehensive
    income.

    During the first three months of 1999 and 1998, total comprehensive loss
    amounted to $1,940,000 and $3,514,000, respectively.

                     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 months ended March 31, 1999 and 1998 should be read in
conjunction with the accompanying unaudited condensed consolidated financial
statements and the related footnotes thereto.

The statements contained in this report, other than statements of historical
fact, constitute forward-looking statements. Such statements include, without
limitation, all statements as to expectation or belief and statements as to the
Company's future results of operations, the progress of the Company's product
development and clinical programs, the need for, and timing of, additional
capital and capital expenditures, partnering prospects, the need for additional
intellectual property rights, effects of regulations, the need for additional
facilities and potential market opportunities. The Company's actual results may
vary materially from those contained in such forward-looking statements because
of risks to which the Company is subject such as Astra AB determining not to
continue support for the Company's encapsulated cell program, failure to obtain
a corporate partner or partners to support the Company's stem cell programs,
negotiations with Genentech, Inc., risks of delays in research, development and
clinical testing programs, obsolescence of the Company's technology, lack of
available funding, competition from third parties, intellectual property rights
of third parties, failure of the Company's collaborators to perform, regulatory
constraints, litigation and other risks to which the Company is subject. See
"Cautionary Factors Relevant to Forward-Looking-Information" filed herewith as
Exhibit 99 and incorporated herein by reference.

OVERVIEW

Since its inception in August 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 
has not commercialized any product and in order for the Company to 
commercialize any product the Company must, among other things, substantially 
increase its research and development expenditures as research and product 
development efforts accelerate and clinical trials are initiated or 
broadened. 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. There can be no assurance that 
such financing or partnering revenues will be available when needed or on 
terms acceptable to the Company. The Company's results of operations have 
varied significantly

                                  Page 8 of 15



from year to year and quarter to quarter 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 OF OPERATIONS
THREE MONTHS ENDED MARCH 31, 1999 AND 1998

For the quarters ended March 31, 1999 and 1998, revenues from collaborative
agreements totaled $2,501,000 and $1,843,000, respectively. This 36% increase in
funding is primarily due to an increase in revenues from a Development,
Marketing and License Agreement with Astra AB, which was signed in March 1995.

Research and development expenses totaled $3,567,000 for the three months ended
March 31, 1999, compared with $4,500,000 for the same period in 1998. The
decrease of $933,000, or 21%, from 1998 to 1999 was primarily attributable to a
reduction in spending on research agreements and a reduction in research and
development personnel expenses.

General and administrative expenses were $995,000 for the three months ended
March 31, 1999, compared with $1,147,000 for the same period in 1998. The
decrease of $152,000, or 13%, from 1998 to 1999 was primarily attributable to a
reduction in recruiting and relocation expenses.

Interest income for the three months ended March 31, 1999 and 1998 was $222,000
and $394,000, respectively. The decrease in interest income in 1999 is
attributable to the lower average investment balances, $15,515,000 vs.
$26,696,000 in the first quarter of 1999 and 1998, respectively.

Interest expense was $94,000 for the three months ended March 31, 1999, compared
with $109,000 for the same period in 1998. The decrease from 1999 to 1998 was
attributable to lower outstanding debt and capital lease balances in 1999
compared to 1998.

Net loss for the three months ended March 31, 1999 was $1,933,000, or $0.10 per
share, as compared to net loss of $3,519,000, or $0.19 per share, for the
comparable period in 1998. The decrease in net loss of $1,586,000, or 45%, from
1998 to 1999 is primarily attributable to a reduction in research and
development spending and a 43% increase in research funding from Astra AB.

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.

                                  Page 9 of 15



The Company had unrestricted cash, cash equivalents and marketable securities
totaling $13,741,000 at March 31, 1999. Cash equivalents and marketable
securities are invested in agencies of the U.S. government, investment grade
corporate bonds and money market funds.


The Company's liquidity and capital resources have been and will continue to be
significantly affected by the Company's relationship with corporate partners.

In March 1995, the Company signed a collaborative research and development
agreement with Astra AB for the development and marketing of certain
encapsulated-cell products to treat pain. Astra made an initial, nonrefundable
payment of $5,000,000, included in revenue from collaborative agreements in
1995, a milestone payment of $3,000,000 in 1997 and may remit up to an
additional $13,000,000 subject to 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 research plan, the Company originally expected to receive
annual payments of $5 million to $7 million from Astra, which was to 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 expiration 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 marketing
license granted to Astra and the Company's obligation to manufacture and supply
products. Astra has had the right to terminate the original agreement since
April 1, 1998. In May 1998, Astra agreed to increase annual research and
development payments from $7 million to $8.5 million for the calendar year 1998.

The current Phase II pain trial completed patient enrollment in March 1999, and
efficacy data from the trial is expected by the third quarter of 1999. Astra has
agreed to fund the first and second quarters of 1999 at the rate of $2.5 million
per quarter. Funding for the second half of 1999 is contingent upon, among other
factors, the results of the current Phase II trial and the results of ongoing
negotiations with Astra with respect to the structure and funding level for the
collaboration beyond the current Phase II trial. Astra has indicated that,
unless it decides to continue the collaborative development program, no
additional funding will be forthcoming in the second half of 1999. Should Astra
discontinue funding for the Company's development of encapsulated-cell products
to treat pain, or reduce funding for such products or otherwise adversely
modify the terms of the

                                  Page 10 of 15



collaborative agreement with the Company, any such action would have a material,
adverse effect on the Company's liquidity and capital resources, and, unless
other funding sources were obtained, would likely result in the Company's
inability to continue to fund further development of its proposed
encapsulated-cell products.

The Company's liquidity and capital resources will also be affected by the
termination of the Company's collaborative development and licensing agreement
with Genentech, Inc. relating to the development of products for the treatment
of Parkinson's disease. On May 21, 1998, Genentech exercised its right to
terminate the Parkinson's collaboration and has requested that the Company
redeem, at a price of $10.01 per share, shares of the Company's Common Stock
having an aggregate value of at least $3.1 million. The Company is negotiating
with Genentech regarding the amount of such redemption (which the Company
currently expects may be approximately $3.1 million) and the manner of payment
for such redemption. Any such redemption will have a material adverse effect on
the Company's liquidity and capital resources.

In May 1996, the Company secured an equipment loan facility with a bank in the
amount of $2,000,000. The Company has borrowed $2,000,000 under this agreement
as of March 31, 1999. The loan required interest payments only for the first two
years; principal payments are payable over a two-year period which began in
August 1998. The loan is secured by equipment purchased with the proceeds of the
credit facility. The current balance on this credit facility as of March 31,
1999 was $1.25 million. The loan agreement requires that, among other covenants,
the Company maintain at all times unrestricted liquidity in an amount equal to
or in excess of $15 million. The Company was in violation of this covenant as of
March 31, 1999, and accordingly has classified the entire debt as current. On
May 6, 1999, the lender granted a waiver of the loan covenant violation in
exchange for the Company making a payment to the lender to reduce the
outstanding principal balance to $750,000 and agreeing to make the final payment
under the loan facility by February 1, 2000. The lender has also reduced the
requirement to maintain unrestricted liquidity to an amount equal to or in
excess of $10 million.

The Company has limited liquidity and capital resources and must obtain
significant additional capital resources in order to sustain its product
development efforts. In both the encapsulated-cell and stem cell areas,
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,
laboratory and office facilities, establishment of production capabilities and
for general and

                                  Page 11 of 15



administrative expenses. The Company's ability to obtain additional capital will
be substantially dependent on Astra's decision regarding continuation of support
for the Company's chronic pain product and the Company's ability to obtain
partnering support for its stem cell technology. Until the Company's operations
generate significant revenues from product sales, cash reserves and proceeds
from equity and debt offerings, 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, grants and collaborative research arrangements. The source,
timing and availability of any future financing will depend principally upon
market conditions, interest rates and, more specifically, on the Company's
progress in its exploratory, preclinical and clinical development programs. 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.

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 quarter of 2000. 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 and/or its capital
expenditures or to outlicense its potential products or technologies to third
parties.


YEAR 2000

The year 2000 problem results from the fact that computer programs were often
written using two digits rather than four to define the applicable year.
Computer programs that have date-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. The Company has tested its
material software applications to determine whether each program is prepared to
accommodate date information for the year 2000 and beyond. The Company found all
of its material software programs to be year 2000 compliant and does not
anticipate any significant disruption of its operations as a result of the
failure of any of its software programs to be year 2000 compliant.

The Company is also testing the status of its facilities systems such as phones,
voice mail, heating/air conditioning, electricity and security systems and its
laboratory and manufacturing equipment to determine if they are year 2000
compliant. The Company expects to complete this testing in the third quarter


                                  Page 12 of 15



of 1999. If any of the systems or equipment is found not to be year 2000
compliant, the Company intends to either seek to repair the systems or equipment
to cause it to be year 2000 compliant or replace such systems or equipment with
year 2000 compliant products. The cost to repair or replace any such system or
equipment that is not year 2000 compliant could be material. The Company is also
polling its major vendors and suppliers to determine if they are year 2000
compliant and to identify any potential issues. Each of the suppliers and
vendors that has responded to the Company's inquiry has confirmed either orally
or in writing that it does not believe that its sales of products or provision
of services to the Company will be interrupted as a result of the year 2000
issue. As a result of its investigations, the Company does not currently believe
that it is reasonably likely that its operations will be significantly impacted
by the year 2000 issue. Although the Company believes that the cost of
remediation associated with achieving year 2000 compliance or the costs
associated with system failures will not be significant, there can be no
assurance that the failure of one or more of the Company's major suppliers to be
year 2000 compliant will not have an adverse effect on the Company's operations
or financial results.
