GRANT

         2.01.     License.

        (a)    Subject to the  fulfillment  by Licensee of all the terms and  conditions of this  Agreement, Centocor hereby grants
to Licensee and Licensee hereby accepts a non-exclusive, non-transferable worldwide sublicense under Licensed Patents for the term
thereof to make, have made, use, offer for sale, sell and import Licensed Products, without the right to grant sublicenses, except
as provided in Section 2.01(b).

        (b)    In the event that Licensee grants a license under Licensee  patent(s) to a third  party(ies) with respect to a
Licensed Product(s), then, with respect to each such Licensed Product, Licensee shall have the right to grant a sublicense under
this Agreement to such third party with respect to such Licensed Product.

         2.02.     Schedule B.    The antibodies listed on Schedule B are explicitly excluded from Products.

         2.03.     No Other License.  Licensee  understands  and agrees that no license under any patent other than Licensed
Patents is or shall be deemed to have been granted to Licensee under this Agreement, either expressly or by implication.

         2.04      Cross License.  Licensee hereby agrees to grant to Centocor,  subject only to Paragraph  2.05(b),  a
royalty-bearing nonexclusive license in the United States, to make, have made, use, offer to sell, sell and import Cross-Licensed
Products under terms and conditions and at a commercially reasonable royalty, all to be negotiated in good faith between the
parties. With respect to terms and conditions other than royalties, the terms and conditions of this Agreement as well as the terms
and conditions of any license agreement under which Centocor receives a sublicense shall be used as guidance in such good faith
negotiation. It is expressly understood that, with respect to patents and patent applications licensed to Licensee, Licensee's
obligations under this Paragraph 2.04 are limited only by Licensee's right to grant sublicenses and if Licensee does not have the
right to grant a sublicense, Licensee shall use reasonable efforts to obtain the right to grant a sublicense and such sublicense
shall be subject to the terms and conditions of the license agreement under which the sublicense is granted. In the event that
Centocor desires to extend the license to Cross-Licensed Products to one or more countries outside the United States, Licensee
agrees to consider extension of the license to one or more of such countries but Licensee shall have no obligation to extend the
license to any country outside the United States.

         2.05      Licensed Products and Cross-Licensed Products.

        (a)    At any time during the term of this  Agreement,  Licensee shall have the right to notify  Centocor in writing that
an antibody (other than an Excluded Product) then in preclinical or clinical development, as those terms are commonly used in the
industry, shall become a Product to be added to Schedule A. Such writing shall include information about such antibody including but
not limited to the following specifics regarding the antigen(s) to which the antibody binds: species or organism; cDNA or primary
amino acid sequence; binding epitope; unique antigenic characteristics of epitope (e.g., aberrant glycosylation pattern, unique
folding etc.), and other information sufficient for Centocor to evaluate the antigen(s) to which said antibody binds. If Centocor
has an antibody or portion thereof in preclinical or clinical development that binds to the same antigen as the antibody as to which
notice has been provided by Licensee under this Paragraph 2.05(a), and within forty five (45) days after receiving the written
notice from Licensee, Centocor by written notice to Licensee designates such Centocor antibody as a Cross-Licensed Product, such
Centocor antibody or portion thereof shall be a Cross-Licensed Product and such antibody designated by Licensee shall be a Product
and shall be added to Schedule A, unless, within thirty (30) days after Licensee receives the written notice from Centocor, Licensee
notifies Centocor in writing that Licensee withdraws such antibody as Product, in which case, such antibody designated by Centocor
shall not become Cross-Licensed Product and such antibody designated by Licensee shall not become Product.

         (b)   If Centocor  fails to provide the written notice of Paragraph  2.05(a)  within the time period of Paragraph
2.05(a), after having received the notice including the specifics to which the antibody binds, an antibody designated by Licensee
under Paragraph 2.05(a) shall become a Product and shall be added to Schedule A within forty five (45) days after Licensee provides
the written notice, and Centocor shall not have the right to designate an antibody that binds to the same antigen as such Licensed
Product as a Cross-Licensed Product.

         (c)   The rights provided to the parties under Section  2.05(a) may be exercised  within the sole discretion of the parties
at any time for one or more antibodies.

         (d)   The withdrawal of an antibody by Licensee under Section  2.05(a) shall not prevent  Licensee from  resubmitting
such antibody in accordance with the provisions of Section 2.05(a).

Article III

FEES AND ROYALTIES

         3.01.     Earned Royalties.  Licensee shall pay to Centocor a royalty of (CONFIDENTIAL  TREATMENT REQUESTED) of total Net
Sales of Licensed Products for each Licensed Product, except for RSV Antibody, which royalties Licensee shall pay to Centocor in
accordance with Paragraphs 3.04 and 3.05 herein.

         3.02.     Sales to and Between Licensee  Affiliates.  No royalties shall be due upon sales of Licensed  Products to and
between Affiliates or from Licensee or an Affiliate to a Related Party for further sale; provided, however, that royalty shall be
payable upon the final sale by the Licensee Affiliate or the Related Party to a non-affiliated vendee.

         3.03.     No  Non-Monetary  Considerations.  Without the prior written consent of Centocor,  Licensee and its Affiliates
shall not solicit or accept any consideration for the sale of any Licensed Product other than as will be accurately reflected in Net
Sales.

         3.04      Running  Royalties  for  RSV  Antibody.  In  consideration  of the  license  granted  herein  as of the  date of
this Agreement, and in lieu of any license grant fee, royalties for RSV Antibody that is a Licensed Product shall be calculated as
follows:

                  a)       subject to Section 3.05,  (CONFIDENTIAL TREATMENT REQUESTED) of Net Sales of RSV Antibody that is a
                           Licensed Product until the cumulative Net Sales of such RSV Antibody from the date of this Agreement
                           amount to  (CONFIDENTIAL TREATMENT REQUESTED), and thereafter,
                  b)       (CONFIDENTIAL  TREATMENT  REQUESTED) of all Net Sales of RSV Antibody  that is a Licensed  Product until
                           the cumulative  Net  Sales of such  RSV  Antibody  from the date of this  Agreement  amount  to
                           (CONFIDENTIAL  TREATMENT REQUESTED), and thereafter,
                  c)       (CONFIDENTIAL TREATMENT REQUESTED) of all Net Sales of  RSV Antibody that is a Licensed Product.

         3.05      Minimum Royalty for RSV Antibody.  Licensee shall pay a minimum  nonrefundable  royalty of (CONFIDENTIAL
TREATMENT REQUESTED) for RSV Antibody that is a Licensed Product. Such minimum royalty shall be calculated as follows: In the event
Net Sales of RSV Antibody fall below (CONFIDENTIAL TREATMENT REQUESTED) in any calendar year, or cease for any reason including but
not limited to the permanent withdrawal from the market, and, in either case, cumulative Net Sales for RSV Antibody for which
royalties were paid or are payable under Section 3.04 have not reached (CONFIDENTIAL TREATMENT REQUESTED), Licensee shall pay
Centocor within 30 days of such event a one-time non-refundable royalty for RSV Antibody which shall be equal to the sum of
(CONFIDENTIAL TREATMENT REQUESTED) of cumulative Net Sales of RSV Antibody, calculated from the date of this Agreement. Thereafter,
any royalties payable with respect to RSV Antibody shall be paid under Paragraph 3.04(b) and (c) rather than Paragraph 3.04(a). As a
representative example, if the conditions of this Paragraph 3.05 are met and sales of RSV Antibody that is a Licensed Product were
(CONFIDENTIAL TREATMENT REQUESTED) to such date, Licensee would pay (CONFIDENTIAL TREATMENT REQUESTED), i.e., payment of
(CONFIDENTIAL TREATMENT REQUESTED) and thereafter any royalties would be paid under Paragraph 3.04(b) and (c) rather than 3.04(a).

Article IV

RECORDS, REPORTS AND PAYMENTS

         4.01.     Records  Retention.  Licensee  agrees and shall cause its  Affiliates  to keep  records of the sales of all
Licensed Products in sufficient detail to permit Centocor to confirm the accuracy of Licensee's royalty calculations. At Centocor's
request and expense, Licensee shall permit an independent certified public accountant appointed by Centocor and acceptable to
Licensee to examine, upon reasonable notice and at reasonable times, and no more than once each calendar year, such records solely
to the extent necessary to verify Licensee's calculations. Such examination shall be limited to a period of time no more than three
(3) fiscal years immediately preceding the request for examination, and shall be at Centocor's request and expense except in the
event that results of the audit reveal a discrepancy in Licensee's favor of 10% or more, then the audit fees shall be paid by
Licensee.

         4.02.     Reports.  Within sixty (60) days after the end of each calendar quarter  following  Licensee's first sale of
Licensed Product, Licensee shall furnish to Centocor a written report of all sales of Licensed Products subject to royalty under
Sections 3.01, 3.03, 3.04, and 3.05, during such calendar quarter. Such report shall include the number and description of Licensed
Products made, sold or otherwise transferred, and the number of patients, if any, in clinical trials. Such report shall further
include (i) the determination of Net Sales as specified in Section 1.08; (ii) the royalty payment then due.

         4.03      Payments.  Concurrently  with each report  pursuant to Section  4.02,  Licensee  shall make the royalty  payment
then due. Payments shall be in United States dollars and, unless otherwise agreed in writing, shall be made by wire transfer to such
bank Centocor may from time to time designate in writing, without set-off and free and clear of and without any deduction or
withholding for or on account of any taxes, duties, levies, imposts, fees or charges.

         4.04.     Currency  Conversion.  Royalties  due on Net Sales of Licensed  Products  made in currency  other than United
States dollars shall first be calculated in the foreign currency and then converted to United States dollars on the basis of the
rate of exchange in effect for purchase of dollars at Chase Manhattan Bank, New York, New York, on the last business day of the
period for which royalties are due.

Article V
LIABILITY

        5.01.      Indemnification.  Licensee  shall defend,  indemnify  and hold  Centocor and Licensor  (and the  trustees,
officers, employees, and agents thereof) harmless against any and all liability, damage, loss, cost or expense resulting from any
claim, suit or other action arising out of or based on Licensee's possession, operation, manufacture, use or sale of any Licensed
Product; except for claims, suits or other actions made by Centocor or its officers, employees or agents, provided, however, that

sole discretion, to enforce Licensed Patents against third party infringers.
