disclaims any and all implied warranties that the information SB provided to
IDEC under this AGREEMENT is necessary or appropriate for FDA or other
regulatory or governmental agency review of COMPOUND except as otherwise
expressly stated in this AGREEMENT. Finally, with respect to COMPOUND,
information, and assistance provided to IDEC under this AGREEMENT, SB disclaims
any warranties or representations, either express or implied, whether in fact or
in law, including without limitation implied warranties of merchantability or
fitness for a particular purpose or noninfringement, except as otherwise
expressly stated in this AGREEMENT.

        3.8 In consideration of execution of this AGREEMENT and the payment by
SB to IDEC of the amount of *_______________________* by March 3, 2000, SB's
obligations under Paragraph 13.01 of the Original Agreement shall be deemed
fulfilled.

substantially to a COMPOUND. This confidentiality obligation shall not apply to
such information which is or becomes a matter of public knowledge, or came or
comes into the possession of the receiving party independently of this
AGREEMENT, or is disclosed to the receiving party by a THIRD PARTY having the
right to do so, or is subsequently and independently developed by employees of
the receiving party or AFFILIATES thereof who had no knowledge of the
confidential information disclosed. The parties shall take reasonable measures
to ensure that no unauthorized use or disclosure is made by others to whom
access to such information is granted. Notwithstanding the foregoing, IDEC shall
be entitled to use, reveal and disclose with and to THIRD PARTIES any
confidential information received from SB which relates to a COMPOUND whether
received pursuant to the AGREEMENT or the Original Agreement without first
obtaining the written consent of SB.

        7.3 No public announcement or other disclosure to THIRD PARTIES
concerning the existence of or terms of this AGREEMENT shall be made, either
directly or indirectly, by either party to this AGREEMENT, except as may be

announcement or other disclosure shall use reasonable efforts to inform the
other party of the proposed announcement or disclosure in reasonably sufficient
time prior to public release, and shall use reasonable efforts to provide the
other party with a written copy thereof, in order to allow such other party to
comment upon such announcement or disclosure.

way inhibiting IDEC or SB from complying with statutory and regulatory
requirements governing the manufacture, use and sale or other distribution of
COMPOUND in any country in the world in any manner it reasonably deems
appropriate, including, for example, by disclosing to regulatory authorities
confidential or other information received from the other or THIRD PARTIES.

THIRD PARTY PATENTS (if any) filed by SB prior to the EFFECTIVE DATE which

anywhere in the world.

        8.2 SB shall prepare, file, prosecute, maintain, extend and defend
patent applications and issued patents included in the licenses granted pursuant
to Section 2 so as to protect the commercial interests of the parties in
COMPOUND in the U.S., Europe and such other countries where patent applications
and issued patents exist as of the EFFECTIVE DATE. SB shall not abandon any such
patent applications in any country without IDEC's written consent. SB shall
promptly advise IDEC of the grant, lapse, revocation, surrender, invalidation,
or abandonment of any patents subject to Section 2 anywhere in the world.
Notwithstanding the foregoing, IDEC shall have the right to assume
responsibility for the preparation, filing, prosecution, maintenance and defense
of any a patent or patent application or any part thereof in any country for
which SB has the right to prosecute and maintain; provided that the claims of
such patents covers COMPOUND. IDEC acknowledges that all right, title and
interest in and to the SB PATENTS in and to the SB PATENTS are and shall remain
in SB, subject to the express license rights granted to IDEC under Section 2 of
this AGREEMENT.

9.      PATENT LITIGATION

        9.1 In the event of the institution of any suit by a THIRD PARTY against
IDEC, SB and/or its sublicensees for patent infringement involving an SB PATENT
or THIRD PARTY PATENT subject to Section 2 anywhere in the world, the party sued
shall promptly notify the other party in writing. IDEC shall have the right but
not the obligation to defend such suit at its own expense. IDEC and SB shall
assist one another and cooperate in any such litigation at the other's request
without expense to the requesting party.

        9.2 In the event that IDEC or SB becomes aware of actual or threatened
infringement of an SB PATENT or THIRD PARTY PATENT subject to Section 2 anywhere
in the world, that party shall promptly notify the other party in writing. IDEC
shall have the first right but not the obligation to bring, at its own expense,
an infringement action or file any other appropriate action or claim directly
related to infringement of a patent or patent application subject to Section 2
wherein such infringement relates to COMPOUND, against any THIRD PARTY and to
use SB's name in connection therewith. If IDEC does not commence a particular
infringement action within ninety (90) days after it received such written
notice, SB, after notifying IDEC in writing, shall be entitled to bring such
infringement action or any other appropriate action or claim at its own expense.
The party conducting such action shall have full control over its conduct. In
any event, IDEC and SB shall assist one another and cooperate in any such
litigation at the other's request without expense to the requesting party.

        9.3 IDEC and SB shall recover their respective actual out-of-pocket
expenses, or equitable proportions thereof, associated with any litigation or
settlement thereof from any recovery made by any party. Any excess amount shall
be shared between SB and IDEC, with each party receiving an amount proportional
to the amount spent by such party on such litigation or settlement thereof
relative to the total amount spent by both parties on such litigation or
settlement thereof.

        9.4 The parties shall keep one another informed of the status of and of
their respective activities regarding any litigation or settlement thereof
concerning COMPOUND.


                                                                              13

        9.5 SB shall authorize IDEC to act as SB's agent for the purpose of
making any application for any extensions of the term of SB PATENTS or THIRD
PARTY PATENTS of which SB is entitled to act as such an agent in any country in
the world in which such extensions are or become available, and shall provide
reasonable assistance therefor to IDEC, AT IDEC'S EXPENSE.


                                                                              14

days of receipt of such invoices.

        10.2 IDEC shall keep and require its AFFILIATES and sublicensees to keep
complete and accurate records of IDEC NET SALES. SB shall have the right, at
SB's expense, through a certified public accountant or like person reasonably
acceptable to IDEC, to examine such records during regular business hours during
the term of this AGREEMENT and for six (6) months after the later of its
termination or the last COMMERCIAL SALE of COMPOUND; provided, however, that
such examination shall not take place more often than once a year and shall not
cover such records for more than the preceding two (2) years; and provided
further that such accountant shall report to SB only as to the accuracy of the
IDEC NET SALES calculations, royalty statements and payments by IDEC to SB under
this AGREEMENT.

        10.3 Within sixty (60) days after the close of each calendar quarter
commencing with the first calendar quarter in which the COMMERCIAL SALE of a
COMPOUND occurs, IDEC shall deliver to SB a true accounting of IDEC NET SALES of
COMPOUND during such quarter and shall at the same time pay all royalties due to
SB under Section 5.1. Such accounting shall show IDEC NET SALES on a
country-by-country and COMPOUND-by-COMPOUND basis. Any tax paid or required to
be withheld by IDEC on account of royalties payable to SB under this AGREEMENT
shall be deducted from the amount of royalties otherwise due. IDEC shall secure
and send to SB written proof of any such taxes withheld and paid by IDEC or its
sublicensees for the benefit of SB in a form sufficient to satisfy the United
States Internal Revenue Service.

        10.4 All royalties due under this AGREEMENT shall be payable in U.S.
dollars. If governmental regulations in a country prevent remittances from IDEC
to SB in U.S. dollars with respect to IDEC NET SALES made in that country, SB
shall receive such royalty payment for IDEC NET SALES in that country in local
currency.

        10.5 Monetary conversions from the currency of a foreign country, in
which COMPOUND is sold, into United States currency shall be made at the average
daily rates of exchange for the year from January 1 to the end of such calendar
quarter, from such country's currency into U.S. Dollars as reported in the Wall
Street Journal or other source agreeable to both parties, and shall be converted
at such average year-to-date rate at the end of such quarter.

employee or agent of SB;
