Item 5.

     On November 25, 1996 the Company entered into three agreements with
Genentech, Inc. ("Genentech") to develop treatments for Parkinson's disease,
Huntington's disease and amyotrophic lateral sclerosis ("ALS"). Under the
agreements the Company and Genentech will pursue treatments for these diseases
that utilize the Company's encapsulated cell technology to deliver several of
Genentech's growth factors, potentially including neurotrophin-4/5 ("NT-4/5"),
cardiotrophin-1 ("CT-1"), Neurturin and nerve growth factor ("NGF"). These
agreements supersede the Development Collaboration and License Agreement between
the Company and Genentech entered into in March 1994 which related in part to
the development of a product for the treatment of Alzheimer's disease using NGF.

     The following is a brief overview of each of the agreements:

DEVELOPMENT COLLABORATION AND LICENSE AGREEMENT RELATING TO PARKINSON'S DISEASE
(THE "PARKINSON'S AGREEMENT")

     The initial focus of the research under the Parkinson's Agreement will be
the development of a treatment for Parkinson's disease using Neurturin. Under
the Parkinson's Agreement, the Company is obligated to perform certain
preclinical studies and a pilot Phase I clinical study using Neurturin (unless
another growth factor is agreed upon by the parties). Genentech has purchased
$8.3 million of the Company's Common Stock (829,171 shares at $10.01 per share)
to fund the Company's expenses associated with such preclinical and pilot
clinical studies. If the parties agree that additional funds are required to
complete such studies, Genentech will purchase additional shares of the
Company's Common Stock (at the then current market price of the Company's Common
Stock) to provide the Company the additional required funding.

     Genentech has the right to terminate development under the Parkinson's
Agreement after the completion of each of (i) the preclinical studies, (ii) the
pilot Phase I clinical trial and (iii) specified Phase II clinical trials.
Should Genentech decide to proceed to Phase II clinical trials, Genentech will
purchase additional shares of the Company's Common Stock (at the then current
market price of the Company's Common Stock) to fund such study. If following
completion of the preclinical studies, the pilot clinical study or the Phase II
study, Genentech decides to terminate further development under the Parkinson's
Agreement or if Genentech terminates the Parkinson's Agreement as a result of a
breach of the Parkinson's Agreement by the Company, and the funds the Company
received from the sale of stock to Genentech pursuant to the Parkinson's
Agreement exceed the expenses incurred by the Company in connection with such
studies by more than $1 million, Genentech has the right to require the Company
to repurchase from Genentech shares of Company Common Stock having a value equal
to the amount of the overfunding (based on the per share price at which
Genentech purchased such shares of Common Stock from the Company). The Company
is obligated to use reasonable efforts to complete its development obligations
under the Parkinson's Agreement within a prescribed period.

     In the event Genentech decides to continue with Phase III clinical trials,
Genentech and the Company will share the cost of U.S. Phase III clinical trials
and Genentech will pay for any clinical testing required to sell products
developed under the Parkinson's Agreement outside the United States. Genentech
will extend the Company a line of credit to provide the Company cash to fund the
Company's share of the expenses of the Phase III trials in the United States.
The line

of credit, together with interest thereon, is repayable, at the option of the
Company, in either cash or through the issuance of shares of the Company's
Common Stock having a value (based on the then current market price of the
Company's Common Stock) equal to the outstanding amount of the loan.

     Upon commercialization, Genentech and the Company will share profits in the
United States at an agreed upon percentage, and Genentech will pay the Company a
royalty based on sales outside the United States. The Company will retain
manufacturing rights and will be paid manufacturing costs for products sold. In
the event the Parkinson's Agreement is terminated because of the Company's
default or bankruptcy, the Company is required to grant Genentech a license to
the Company's cell encapsulation technology and transfer to Genentech related
technology for use solely with the products developed under the Parkinson's
Agreement.

     Under the Parkinson's Agreement, the Company has granted Genentech an
exclusive license to use the Company's cell encapsulation technology with
certain of Genentech's growth factors for the treatment of Parkinson's disease.
Under the Parkinson's Agreement, the Company is also prohibited from entering
into certain agreements relating to the development of treatments for
Parkinson's disease using certain compounds.

LICENSE AGREEMENT RELATING TO TREATMENT OF HUNTINGTON'S DISEASE (THE
"HUNTINGTON'S AGREEMENT")

     Under the Huntington's Agreement, Genentech has granted the Company an
exclusive license to CT-1 to develop, make, use and sell products for the
treatment of Huntington's disease that utilize CT-1 and the Company's cell
encapsulation technology. The Company is responsible for all preclinical and
clinical development under the Huntington's Agreement, including all expenses
associated with such development. The Company will pay Genentech a royalty based
on net sales of any products developed under the Huntington Agreement. The
Company's license to CT-1 is dependent upon the Company using reasonable efforts
to achieve certain development milestones within prescribed periods.

     Upon the earlier of (i) the Company agreeing to grant a third party
sublicense rights under the Huntington's Agreement, and (ii) the successful
completion of the specified Phase II trial on a product developed under the
Huntington Agreement, Genentech has the option to require the Company to
negotiate exclusively with Genentech for a limited period regarding Genentech
co-developing and co-marketing products developed under the Huntington's
Agreement. In the event the parties are unable to reach an agreement, the
Company would have the right to sublicense its rights under the Huntington's
Agreement to a third party, provided such third party offers the Company terms
more favorable to the Company than the terms of Genentech's last offer. In the
event the Huntington's Agreement is terminated because of the Company's default
or bankruptcy, the Company is required to grant Genentech a license to the
Company's cell encapsulation technology and transfer to Genentech related
technology for use solely with products developed under the Huntington's
Agreement.

LICENSE AGREEMENT BETWEEN THE COMPANY AND GENENTECH RELATING TO TREATMENT OF
AMYOTROPHIC LATERAL SCLEROSIS (THE "ALS AGREEMENT")


                                       -3-

     Pursuant to the ALS Agreement, Genentech has granted the Company a license
to CT-1 and NT-4/5 to develop products for the treatment of ALS using the
Company's cell encapsulation technology. Subject to certain limitations
discussed below, the Company is responsible for all expenses associated with the
preclinical and clinical development under the ALS Agreement and is obligated to
pay Genentech royalties on net sales of products developed under the ALS
Agreement. The Company's license to CT-1 and NT-4/5 is dependent upon the
Company using reasonable efforts to achieve certain development milestones
within prescribed periods.

     Upon the successful completion of the specified Phase II clinical trial,
Genentech has the option to obtain exclusive rights to sell products developed
under the ALS Agreement in the United States by agreeing to pay an agreed upon
percentage of the expenses of United States Phase III clinical development of
such products. If Genentech makes such an election, the parties will share
profits on sales of such products in the United States. In all events, the
Company would continue to have the exclusive right to sell products developed
under the ALS Agreement outside the United States, subject to a royalty payable
to Genentech. In the event the ALS Agreement is terminated because of the
Company's default or bankruptcy, the Company is required to grant Genentech a
license to the Company's cell encapsulation technology and transfer to Genentech
related technology for use solely with the products developed under the ALS
Agreement.
