     15.5 Survival of Obligations.
          ------------------------

          15.5.1  Neither the termination nor expiration of the Co-promotion
Term shall release or operate to discharge any Party from any liability or
obligation that may have accrued prior to such termination or expiration or
constitute a waiver or relinquishment of any cause of action or claim that a
Party may have based on events, acts or omissions occurring prior to such
termination date. Any termination of the Co-promotion Term by a Party shall not
be an exclusive remedy, but shall be in addition to any legal or equitable
remedies that may be available to a Party and shall not affect a Party's rights
to indemnification that are expressly set forth in this Agreement. The mere
termination of this Agreement in accordance with its terms shall not, in and of
itself, give rise to any damages or liability on the part of the terminating
Party.

          15.5.2  The following provisions shall survive any termination of this
Agreement:  Articles 16 and 17 and Sections 4.8.2.6, 4.8.4.6, 6.1.1, 6.1.5,
6.2.1 and 6.2.5, as well as any other provisions, which, by their intent or
meaning, are intended to so survive.

             notice of any claim or potential claim promptly after the
             Indemnitee receives notice thereof; provided that failure of the
                                                 --------
             Indemnitee to provide such notice shall not constitute a waiver of,

             under this Agreement, except in the event that the Indemnitor's
             rights, and/or its ability to defend against or settle such claim
             or potential claim, are materially prejudiced by such failure to
             notify;

     (ii)    allow the Indemnitor to assume the control of the defense and
             settlement (including all decisions relating to litigation, defense

             has confirmed its indemnification obligation to the Indemnitee
             under this Article 16, and (b) no such settlement may materially
             adversely affect the rights or obligations of the Indemnitee under

             available for pertinent interview and testimony), so long as such

             Indemnitee is entitled.

attorneys of its choice, participate in, but shall not have any control of, the

PARTNERS or the continuing payment of any monies by the INTEGRILIN PARTNERS
under the previous sentence shall not require GENENTECH's consent, even though
it may have an effect on Performance Compensation), or (b) admits liability on
the part of GENENTECH, or (c) results in any damages payable by GENENTECH that

ARTICLE 20. Miscellaneous Provisions.
            -------------------------

     20.1   Assignment.
            ----------

            20.1.1 No Party shall assign or otherwise transfer this Agreement or
any interest herein or right hereunder without the prior written consent of the
other Parties, and any such purported assignment, transfer or attempt to assign
or transfer any interest herein or right hereunder shall be void and of no
effect; except that each Party (i) may assign its rights and obligations
hereunder to an Affiliate (in the case of Schering, to a wholly owned subsidiary
of Schering Plough Corporation) without the prior consent of the other Parties
(although, in such event, the assigning Party shall remain [*] with such
Affiliate for the performance of all of representations, warranties, obligations
and agreements of the assigning Party set forth herein) and (ii), except as set
forth in Sections 2.4 and 3.4, may assign its rights and obligations to a
successor (whether by merger, consolidation, reorganization or other similar
event) or purchaser of all or substantially all of its business assets relating
to the Products; provided, that such successor or purchaser has agreed in
                 --------
writing to assume all of such Party's rights and obligations hereunder and a
copy of such assumption is provided to the other Party hereunder.

     20.2   Non-Waiver. Any failure on the part of a Party to enforce at any
            ----------
time or for any period of time any of the provisions of this Agreement shall not
be deemed or construed to be a waiver of such provisions or of any right of such
Party thereafter to enforce each and every such provision on any succeeding
occasion or breach thereof.

     20.3   Entirety of Agreement. This Agreement contains the entire
            ---------------------
understanding of the Parties with respect to the subject matter hereof and
thereof and supersedes all previous and contemporaneous verbal and written
understandings, agreements, representations and warranties with respect to such
subject matter or on which the Parties may have relied. This Agreement (and any
provision or term hereof) may be released, waived, changed or supplemented only
by a written agreement signed by an officer or other authorized representative
of the Party or Parties against whom enforcement of any release, waiver, change
or supplement is sought. This Agreement shall not be strictly construed against
any Party hereto. Paragraph headings are for convenience only and shall not be
considered in interpreting this Agreement.

     20.4   Public Announcements. The form and content of any public
            --------------------
announcement to be made by one Party regarding this Agreement, or the subject
matter contained herein, shall be subject to the prior written consent of the
other Parties (which consent may not be unreasonably withheld), except as may be
required by applicable law (including, without limitation, disclosure
requirements of the SEC, NASDAQ, or any other stock exchange) in which event the
disclosing Parties shall endeavor to give the other Parties reasonable advance
notice and review of any such disclosure.

     20.5   Governing Law. This Agreement shall be governed by and construed in
            -------------

giving effect to its conflicts of law principles.

     20.6   Relationship of the Parties. In making and performing this
            ---------------------------
Agreement, the Parties are acting, and intend to be treated, as independent
entities and nothing contained in this Agreement shall be construed or implied
to create an agency, partnership, joint venture, or employer and employee
relationship between GENENTECH, COR and SCHERING. The relationship of the
Parties under this AGREEMENT is, and is intended to be, one of independent
contractors hereunder.

     20.7   Collaboration Agreement.  SCHERING and COR are parties to that

Collaboration Agreement dated April 10, 1995 as amended on December 23, 1998 and

Collaboration Agreement"). The INTEGRILIN Collaboration Agreement shall govern
the relationship between SCHERING and COR with respect to the subject matter of
this Agreement, including the apportionment of duties, rights and
responsibilities between the two Parties, provided that nothing in the
INTEGRILIN Collaboration Agreement shall relieve either SCHERING or COR of any
individual or joint responsibility they have to GENENTECH under this Agreement.

            No Party shall have any responsibility for the hiring, firing,
compensation or benefits of another Party's employees, and all compensation and
benefits to be paid to any employee or representative of a Party (including
without limitation all Sales Force Personnel engaged by a Party) shall be the
responsibility of the Party engaging such individual.
