AMENDED AND RESTATED IL-13 LICENSE AGREEMENT
BY AND BETWEEN THE UNDERSIGNED :
IDM, a French société anonyme with a capital of 1 569 444,60 Euros having its
principal place of business at 172 rue de Charonne, Paris (75011) and registered
at the Paris Register of Trade and Companies under B 382 632 263 represented by
Jean-Loup Romet-Lemonne, President and CEO (hereinafter, “IDM”).
AND:
SANOFI-AVENTIS, a French société anonyme with a capital of 2 791 376 578 Euros
having its principal place of business at 174, avenue de France, 75013 Paris,
and registered at the Paris Register of Trade and Companies under 395 030 844,
represented by Jean-Pierre KERJOUAN, Advisor to the President and General
Counsel, and Mr. Jean-Claude MULLER, Senior Vice President Scientific and
Medical Operations Administration and Ressources (hereinafter “SANOFI-AVENTIS”);
IDM and SANOFI-AVENTIS being referred to hereinafter individually as « a Party »
or jointly as « the Parties ».
PRELIMINARY CONSIDERATIONS:
SANOFI-AVENTIS has designed and development a cytokine known as Interleukin
IL-13 (or IL-13) for which it has applied for patents and developed knowhow;
For its part, IDM has acquired and developed substantial knowhow and is the
holder of patents and relative patent applications, in particular for ex vivo
cancer therapies, marketed in the form of research kits and cell processors.
On July 13, 1999, the Parties executed an agreement, which was cancelled and
replaced by an amendment dated November 30, 2001 (hereinafter, the “IL-13
Agreement”), defining the conditions under which SANOFI-AVENTIS granted IDM a
non-exclusive license to its IL-13 Industrial Property rights for the
implementation of Phase I and II Studies on one or more IL-13 Products and the
marketing of IL-13 Research Kits in return for SANOFI-AVENTIS’ taking a stake in
the capital of IDM.
This amendment dated November 30, 2001 was further amended by amendment number 1
dated March 30, 2005, both amendments being collectively called the “IL-13
Agreement”.
The Parties also entered into a Memorandum of Agreement on July 20, 2001,
pursuant to which SANOFI-AVENTIS has, on the terms and conditions defined in
such Memorandum of Agreement, a right of first refusal to all IDM development

--------------------------------------------------------------------------------

 

programs in the field of ex vivo cell therapy in humans, whether or not they
pertain to IL-13 (hereinafter, the “2001 Agreement”).
Pursuant to provisions of article 8.2 of the IL-13 Agreement and pursuant to
information received from IDM related to the change of control of IDM that will
result from the announced combination between IDM and Epimmune Inc.,
SANOFI-AVENTIS notified IDM of its decision to proceed with an early exercise of
BSA1 and BSA2 warrants, such notification being equivalent to exercise of Option
1 and Option 2 (as defined in the IL-13 Agreement).
Option 1 and Option 2 being therefore exercised pursuant to provisions of the
IL-13 agreement, both Parties must therefore enter into the IL-13 License
Agreement and the Amendment to the IL-13 License Agreement as annexed to the
IL-13 Agreement. For the sake of simplicity, both Parties agreed to enter into
the Amended and Restated License Agreement in order to benefit from a single
document that includes all provisions of the IL-13 License Agreement and the
Amendment to the IL-13 License Agreement, after removal of several provisions
that are now obsolete.

5.1.   Without prejudice to the provisions of common law, IDM shall assume any
responsibility that might arise from the implementation of the IL-13 Development
Programs, as well as from the exploitation of the results, vis-à-vis any Third
Party and on any basis whatsoever, and in particular on the basis of civil
liability, in particular with respect to any damage that might result from the
use (in carrying out the Phase I and II Studies) of the IL-13 shipped by
SANOFI-AVENTIS and not manufactured in accordance with “Good Manufacturing
Practices”).       IDM alone shall also assume any liability that might arise
(i) from any fault committed by it or by any IDM Affiliate or sub-licensee
within the context of the implementation of this IL-13 Agreement, as well as
(ii) for any failure on its part or on the part of any IDM Affiliate or
sub-licensee to perform its obligations pursuant to said IL-13 Agreement.      
IDM shall also hold SANOFI-AVENTIS harmless with regard to any harmful
consequences that might arise for SANOFI-AVENTIS from any action brought against
SANOFI-AVENTIS by a Third Party based on damage of any kind whatsoever resulting
from the circumstances indicated above.       IDM warrants that it has taken
out, at its sole expense, the necessary insurance coverage on terms and
conditions consistent with the practices in the pharmaceutical industry, in

at the request of SANOFI-AVENTIS.   5.2.   Without prejudice to the provisions
of common law, SANOFI-AVENTIS shall assume the liability that could result
(i) from any fault committed by it or by any Affiliate or sub-licensee of
SANOFI-AVENTIS within the context of the execution of this IL-13 Agreement,
(ii) of any failure by it or by any SANOFI-AVENTIS Affiliate or sub-licensee to
meet the its obligations under said Agreement as well as (iii) the shipment by
it of IL-13 that is not up to the contractual specifications.      
Consequently, it guarantees IDM against all prejudicial consequences that might
arise for IDM from an action brought against it by a Third Party based on damage
of any kind whatsoever resulting from the circumstances identified above.      
SANOFI-AVENTIS guarantees that it has taken out the necessary insurance at its
sole expense, on terms and conditions consistent with the practices of the
pharmaceutical industry, in order to provide sufficient coverage of the risks
likely to arise from the quantities of supplied IL-13.   5.3.   The above
provisions do not apply to the SANOFI-AVENTIS IL-13 Development Programs, which
are governed by the 2001 Agreement.

6.1.   Existence of the IL-13 Intellectual Property and maintenance of IL-13
Patents       SANOFI-AVENTIS guarantees to IDM the existence of the IL-13
Patents and IL-13 Know-how and the accuracy of its facts. In addition,

Know-how and guarantees that it can freely and validly grant the rights to said
IL-13 Patents and IL-13 Know-how that it is granting under this IL-13 Agreement,
the Contributions Agreement, the IL-13 License Agreement and the Amendment to
the IL-13 License Agreement. The above guarantees are made subject to the
statements included in Annex 10 of the IL-13 Agreement, in particular as regards
the existence on the territory of the United States of patents filed by
[...***...] SANOFI-AVENTIS agrees to keep the IL-13 Patents in force in
accordance with applicable legal and regulatory provisions, in particular by
carrying out, at the appropriate time, necessary procedures and formalities,
provided that, in the event of an extension of the IL-13 Patents or
corresponding supplementary protection certificates, IDM has provided it with
all necessary documents and signatures, when the MA of the Final IL-13 Product
is not in the name of SANOFI-AVENTIS. All costs pertaining thereto shall be paid
by SANOFI-AVENTIS.   6.2   6.2 Defense of IL-13 Intellectual Property      
SANOFI-AVENTIS will have the obligation, at its sole expense :

both in France and abroad, all actions permitted by law to the holder of IL-13
Intellectual Property ;     (b)   to inform IDM as soon as possible of all

    IDM shall have the obligation, at its sole expense, to advise SANOFI-AVENTIS
of any breach by Third Parties of the IL-13 Intellectual Property rights of
which it may have knowledge.       The Parties, in view of the fact that certain

conditions, at least equal to the most favorable conditions offered to any Third
Party, during the life of the IL-13 Agreement and of this Agreement.   7.1.2.

provisions of Article 7.1.1, it is expressly agreed by the Parties that the
transfer of Improvements by SANOFI-AVENTIS shall not entail any change to the

to this Agreement.   7.2.   Improvements made or acquired by IDM
