         WHEREAS, Sanofi and Regeneron are parties to a Discovery and Preclinical
Development Agreement dated as of November 28, 2007 (the “Original Agreement”); and

     

         WHEREAS, the Parties have undertaken a broad therapeutic antibody
discovery and development program under the Original Agreement with the
objective of identifying and validating potential drug discovery targets for the
purpose of discovering fully human monoclonal antibody product candidates
against those targets using Regeneron’s proprietary VelocImmune® and related
suite of technologies;

     

         WHEREAS, the Parties plan to expand these antibody discovery and
development efforts under the terms set forth in this Agreement; and


     

         WHEREAS, Sanofi is interested in continuing to collaborate with Regeneron
to discover and validate potential drug discovery targets for the purpose of
discovering fully human monoclonal antibody product candidates and to receive an
option to license certain rights to the resulting fully human monoclonal
antibodies under the terms set forth in this Agreement and in the License and

    DISCOVERY PROGRAM 

     

              2.1 Discovery Program. (a) From the Effective Date, the objective
of the Parties during the Discovery Program is for Regeneron to discover,
identify and/or validate Targets from which Regeneron shall select Targets for
the Rolling Target List, generate MTCs (and, if agreed to by the JRC, other
Antibodies) against Program Targets (including Program Targets that are Sanofi
Targets) from which to select Lead Candidates, and develop such Lead Candidates
through IND Preparation to offer to Sanofi for joint development and
commercialization under the terms set forth herein and in the License and
Collaboration Agreement. During the first ten (10) Contract Years, Regeneron
will use Commercially Reasonable Efforts to discover, identify and validate
Targets as part of the Discovery Program. The Parties will select Targets for
the Rolling Target List pursuant to Section 2.4. *******************************************.
Regeneron will use Commercially Reasonable Efforts to generate MTCs (and if
agreed by the JRC, other Antibodies) against Program Targets and manufacture
preclinical and clinical supplies of the Lead Candidates and Product Candidates
for the Discovery Program and Phase 1 Clinical Trials. The JRC will evaluate and
prioritize Program Targets. Subject to the JRC’s prioritization of Program
Targets, Sanofi’s Target selection and exclusion rights under Section 2.4, and the other terms of this Agreement,
Regeneron will have sole responsibility for the design and conduct of all
activities under the Discovery Program, including, without limitation, decisions
relating to initiation and termination of programs and activities, manufacturing
activities, and staffing and resource allocation between different programs and
activities in the Discovery Program. The JRC will also prioritize the
Antibodies, including MTCs, to be further pursued as Lead Candidates, and
Regeneron will commence IND Preparation activities only for those Antibodies,
including MTCs, that meet the applicable criteria set forth in Schedule 4.
Sanofi shall be responsible for completing relevant portions of Schedule 4 for
all Sanofi Targets at the time that such Target is selected for the Rolling
Target List to the extent such information is not available at Regeneron.
Sanofi, through the JRC, will provide consultation and advice to support
Regeneron’s efforts. Neither Regeneron nor Regeneron’s representative on the JRC
shall have the right to discriminate against Sanofi Targets without the
agreement of Sanofi’s representatives on the JRC. 

     

    11 

     

    

    
    


                   (b) In addition to the broad objectives of the Parties set forth in
Section 2.1(a), above, commencing from Contract Year 3
(January 1, 2010) and except as set forth in Section 4.9, the annual objectives of the Discovery
Program for each Contract Year through the Discovery Expiration Date (the
“Collaboration Objectives”) are **********************. Regeneron shall
use Commercially Reasonable Efforts to achieve the Collaboration Objectives. For
the avoidance of doubt, (i) nothing in the preceding sentence shall require
Regeneron to use efforts beyond the FTEs and Out-of-Pocket Costs reimbursed by
Sanofi under this Agreement, and (ii) if Regeneron exercises Commercially
Reasonable Efforts to achieve the Collaboration Objectives, then the failure to
achieve the Collaboration Objectives shall not be considered a breach of this
Agreement. 

     

                   (c) As part of the Discovery Program, Regeneron may
***********************************************.

     

              2.2 Term of the Discovery
Program. The Discovery
Program commenced on the Original Agreement Effective Date and shall end on
December 31, 2017 unless (a) this Agreement is earlier terminated in accordance
with Article 12, in which event the Discovery Program shall
end on the effective date of such termination or (b) extended by Sanofi for the
Tail Period pursuant to the terms of Section 2.9 in which event the Discovery Program shall
end upon the earlier of the expiration of the Tail Period or the earlier
termination of this Agreement.

     

              2.3 Discovery Plans. Regeneron will annually prepare a
“Target Discovery
Plan” and an “Antibody Discovery Plan” for the Discovery Program.

     

                   (a) The Target Discovery Plan shall set forth the overall strategy, plan and
goals over the next Contract Year for identifying and validating Targets from
which Regeneron shall choose its Targets for the Rolling Target List; it being
understood that the Target Discovery Plan will not include information on the
identity of Targets that are the subject of Regeneron’s discovery research
activities under the Discovery Program that have not yet been selected as
Program Targets. The Target Discovery Plan will also include an estimated budget
for the portion of the Discovery Program covered by the Target Discovery Plan
for the ensuing Contract Year. Regeneron will submit each Target Discovery Plan,
including the estimated budget, to the JRC for review and
comment. 

     

    12 

     

    

    
    


                   (b) The Antibody Discovery Plan shall set forth the overall strategy and
plans over the next Contract Year for generating Antibodies against Program
Targets, conducting research on Program Targets and Antibodies generated against
Program Targets, and preclinically developing Antibodies under the Discovery
Program through IND Preparation. The Antibody Discovery Plan will also include
an estimated budget for the portion of the Discovery Program covered by the
Antibody Discovery Plan for the ensuing Contract Year. Regeneron will submit
each Antibody Discovery Plan, including the estimated budget, to the JRC for
review and comment. For each Lead Candidate, the Antibody Discovery Plan will
include activities and a planned timeline for IND Preparation. Regeneron shall
consider in good faith comments on the Antibody Discovery Plan from Sanofi’s
representatives on the JRC.

     

                   (c) Except for the initial Target Discovery Plan and Antibody Discovery Plan
(which will be provided to the JRC within ninety (90) days of the Effective
Date), Regeneron will present an updated Target Discovery Plan and Antibody
Discovery Plan to the JRC at least two (2) months prior to the end of each
Contract Year.

     

              2.4 Target List. 

     

                   (a) Subject to the other terms of this Section 2.4, (i) the Rolling Target List will include up
to ************ designated for Immunization in each two-consecutive Contract
Year period, and ******************************** (all such Targets selected by
Sanofi for the Rolling Target List pursuant to this Section 2.4 being referred to as “Sanofi Targets”). The Parties shall conduct a meeting of the
JRC within ten (10) Business Days of the Effective Date (the “Special JRC Meeting”) to ******************************. The
Rolling Target List will be updated on an annual basis at a meeting of the JRC
to be held in January of each Contract Year, commencing in 2010 and ending in
2017 (the “Annual Draft Meeting”). At least thirty (30) days prior to the
Annual Draft Meeting to be held in 2017, Regeneron shall provide to Sanofi
information on the identity and status of Targets validated by Regeneron under
the Discovery Program that were not previously selected as Targets on to the
Rolling Target List. Targets on the Rolling Target List are progressed from the
Rolling Target List to the Immunized Target List at commencement of
Immunization. Any Targets on the Rolling Target List which have not progressed
to the Immunized Target List during a Contract Year shall remain on the Rolling
Target List, subject to Sections 2.4(b), 2.4(c), and 2.8 below. At each Annual Draft Meeting, the
Parties shall select Targets for the Available Slots to bring the total number
of Targets on the Rolling Target List back to *******. At the Special JRC
Meeting and each Annual Draft Meeting, the Parties shall alternate selecting
Targets for the Available Slots on the Rolling Target List, with Sanofi
designating first, Regeneron second and the process repeating until Sanofi has
selected as many Targets as it desires up to ****************. Regeneron shall
designate all Targets for the Available Slots remaining after Sanofi’s
selections pursuant to this Section 2.4(a). For clarity, an Excluded Target cannot be
selected onto the Rolling Target List without the mutual consent of the Parties.
All Targets selected by the Parties for the Rolling Target List pursuant to this
Section 2.4 shall be identified by their HUGO name, if
applicable.

     

    13 

     

    

    
    


                   (b) Targets may be removed from the Rolling Target List or replaced by new
Targets at any time prior to Immunization by the mutual written consent of the
Parties. Targets removed (either by removal or replacement) from the Rolling
Target List pursuant to this Section 2.4(b) shall become Excluded Targets. Each Party
shall have the right to select up to ******************************* to be added
to the Rolling Target List outside the applicable Annual Draft Meeting at any
time during each Contract Year (such Party being a “Pre-Selecting Party”). The applicable Pre-Selecting Party shall
be considered to have included the applicable Target(s) onto the Rolling Target
List upon its written notice to the other Party. Unless the Target selected by
the Pre-Selecting Party is excluded or removed from the Rolling Target List
pursuant to Section 2.4(c) or Section 2.8, it shall be considered one of the Targets
selected by the Pre-Selecting Party for the Rolling Target List at the next
scheduled Annual Draft Meeting and the number of Targets the Pre-Selecting Party
may select for the Available Slots at such Annual Draft Meeting shall be reduced
accordingly. In addition, Regeneron shall have the right to replace a Target
removed from the Rolling Target List by Sanofi pursuant to Section 2.8 at any time during each Contract Year upon
written notice to Sanofi.

     

                   (c) Sanofi shall have the right to exclude from the Rolling Target List a
Target selected by Regeneron for the Rolling Target List as provided in Section 2.4(c)(i), and shall have the
right to remove a Program Target from the Target List, as provided in
Sections 2.4(c)(ii) and (iii).

     

                   (i) Sanofi shall have the right to exclude from the Rolling Target List a
Target selected by Regeneron for the Rolling Target List (a “Regeneron Selected Target”) if *************.

     

                   (ii) ******************************. 

     

                   (iii) ******************************. 

     

                   (d) Within sixty (60) days after the end of Contract Year 5 (ending December
31, 2012), the Executive Officers of both Parties may agree that the maximum
percentage of Targets that Sanofi may select for the Rolling Target List should
change *************************. In deciding whether to make such a change, the
Executive Officers shall take into consideration, among other criteria agreed to
by the Executive Officers, ******************************************. If the
Executive Officers both agree to change the maximum percentage of Targets Sanofi
may select for the Rolling Target List, then the Parties will promptly enter
into an amendment to this Agreement solely for the purpose of amending the terms
of Section 2.4(a) to reflect the new agreed upon percentage for
each of the remaining Contract Years for which the Rolling Target List has not
been designated. 

     

              2.5 Commercially Reasonable Efforts; Compliance
with Laws. During the term
of the Discovery Program, Regeneron will use Commercially Reasonable Efforts to
discover and develop Product Candidates to offer for license to Sanofi pursuant
to the Opt-In Rights. Without limiting the foregoing, Regeneron will use
Commercially Reasonable Efforts to identify Lead Candidates and complete IND
Preparation for Lead Candidates in a timely manner during the term of the
Discovery Program. Each Party hereby covenants and agrees to comply with
applicable Laws in performing activities connected with the Discovery Program.


     

    14 

     

    

    
    


              2.6 Exchange of Information. Regeneron will share information with the
JRC in a timely manner concerning the progress of the Target Discovery Plan and
the Antibody Discovery Plan consistent with Sections 2.3 and 3.1(b). Without limiting the foregoing, at least
five (5) calendar days prior to each regular quarterly meeting of the JRC,
Regeneron will use its Commercially Reasonable Efforts to provide to Sanofi’s
representatives on the JRC a written report (in electronic form) summarizing the
material activities undertaken by Regeneron in connection with the Target
Discovery Plan and the Antibody Discovery Plan, including information concerning
new Program Targets, Lead Candidates and Product Candidates. Sanofi shall have
the right to reasonably request and to receive in a timely manner clarifications
and answers to questions with respect to such reports (other than with respect
to the identity and progress of Targets in the Target Discovery Plan which are
not Program Targets) and any other data and any other information it reasonably
requests with respect to the conduct of the Target Discovery Plan and the
Antibody Discovery Plan.

     

              2.7 Further Assurances and Transaction
Approvals. Upon the terms
and subject to the conditions hereof, each of the Parties will use Commercially
Reasonable Efforts to (a) take, or cause to be taken, all actions necessary,
proper or advisable under applicable Laws or otherwise to consummate and make
effective the transactions contemplated by this Agreement, (b) obtain from the
requisite Governmental Authorities any consents, licenses, permits, waivers,
approvals, authorizations, or orders required to be obtained or made in
connection with the authorization, execution, and delivery of this Agreement and
the consummation of the transactions contemplated by this Agreement, and (c)
make all necessary filings, and thereafter make any other advisable submissions,
with respect to this Agreement and the transactions contemplated by this

                   (i) General. Subject to the other subparagraphs in this
Section 2.8, until the end of the Term, neither Party nor
any of their respective Affiliates will either directly, or with any Third
Party, work to discover Antibodies against, or develop or commercialize
Antibodies against, Program Targets in the Territory, except pursuant to this
Agreement or the License and Collaboration Agreement. Furthermore, subject to
the other subparagraphs in this Section 2.8, until the earlier to occur of (A) the
Discovery Expiration Date, and (B) the effective termination of this Agreement,
neither Regeneron nor any of its Affiliates will, either directly or with any
Third Party, work to discover, develop or commercialize Antibodies in the
Territory, except pursuant to this Agreement or the License and Collaboration
Agreement. Solely as used in this Section 2.8(a) and in Section 2.8(b), the terms “develop,” “developing” or
“development” shall mean any and all
activities related to Antibody discovery and Antibody preclinical and clinical
development. In the event this Agreement is terminated early pursuant to
Sections 12.2, 12.3, 12.4, 12.5, or 12.11, the obligations stated in this Section 2.8(a) shall also terminate as of the effective date

                   (ii) Third Party Opportunities. Subject to the other sub-paragraphs in this
Section 2.8, as part of the Discovery Program, the
Parties may evaluate new Targets, Antibodies, and antibody technologies owned or
controlled by Third Parties (“Third Party Opportunities”) to determine whether such Targets,
Antibodies or antibody technologies should be licensed or acquired by the
Parties for the Discovery Program. Should a Party identify such a Third Party
Opportunity that it is interested
in acquiring or licensing for inclusion in the Discovery Program, it shall
notify the other Party for consideration and discussion. If the Parties approve
the inclusion of such Third Party Opportunity in the Discovery Program, the
Parties shall decide which Party will license or otherwise acquire rights to the
Third Party Opportunity and include the applicable Target, Antibody or antibody
technology, as the case may be, in the Discovery Program.

right to develop and commercialize Acquired Antibodies **********************,
whether such acquisition is by direct acquisition, by license or through
acquisition of a Third Party) (a “Sanofi Acquired Antibody”), even if such Sanofi Acquired Antibodies
are against Program Targets. Sanofi shall promptly notify Regeneron of any such
acquisition or license (including the identity of the Program Target), and may
continue the development of such Sanofi Acquired Antibody without restriction outside the Discovery
Program and this Agreement. In the event of such an acquisition or license,
unless otherwise agreed to by the Parties, the applicable Program Target shall
be considered an Excluded Target and Sanofi shall no longer have any rights to
any Excluded Candidates against such Excluded Target developed under this
Agreement (such Antibodies being referred to herein as “Sanofi Divested Antibodies”). Regeneron may develop and commercialize
(on its own or with one or more Third Parties) any Sanofi Divested Antibodies or
other Excluded Candidates against such Excluded Targets, and may practice and
use any Regeneron Intellectual Property, including, without limitation, the
Mice, in connection with such activities without restrictions under this
Agreement, subject to the royalty obligations set forth in Section 4.5. Until the time of IND filing for a Sanofi
Divested Antibody, Regeneron shall have the right to consider development of
Sanofi Divested Antibodies against the applicable Excluded Target as development
under the Discovery Program solely for purposes of seeking reimbursement of
Discovery Program Costs pursuant to Section 4.2.

     

                   (iv) Company Acquisitions For clarification, where a Party or its
Affiliate acquires rights to an Acquired Antibody by the acquisition of a Third
Party or part or the whole of its business, the applicable acquiring Party may
as an alternative to any obligations herein, divest such Acquired Antibody (by
sale or license) *********************************. 

     

                   (v) Regulatory Divestitures. In the event that Sanofi acquires rights to
an Acquired Antibody as a result of its acquisition of a Third Party and
believes, based on the reasonable advice of its outside legal counsel, that it
is required by Law to divest its interest in the Antibodies against a Program
Target, then Sanofi shall have the right to exclude such Program Target from the
Discovery Program, and develop and commercialize such Acquired Antibodies
against such Program Target outside the Discovery Program and the terms of this
Agreement. Sanofi shall no longer have any rights to any Antibodies, including
MTCs, against such Program Target under this Agreement (“Sanofi Regulatory Divested Antibodies”) ***********************.
*************************. Either Party shall have the right to develop and
commercialize Antibodies against Target(s) of the Sanofi Regulatory Divested
Antibodies outside the Discovery Program and the terms of this Agreement, and
Regeneron shall have and retain exclusive rights to any Antibodies, including

    21 

     

    

    
    


                   (b) Executive Officers’ Resolution of
Disputes. In the event
that the JRC is, after a period of thirty (30) days from the date a matter is
submitted to it for decision, unable to make a decision due to a lack of
required unanimity, or the Parties are unable to agree on the budget for the
Initial Development Plan for a Product Candidate in accordance with Section 5.3 below, either Party may require that the
matter be submitted to the Executive Officers for a joint decision. In such
event, the co-chairpersons of the JRC, by written notice to each Party delivered
within five (5) days after receipt of the notice from a Party pursuant to the
immediately preceding sentence, shall formally request that the dispute be
resolved by the Executive Officers, specifying the nature of the dispute with
sufficient specificity to permit adequate consideration by such Executive
Officers. The Executive Officers shall diligently and in good faith, attempt to
resolve the referred dispute within thirty (30) days of receiving such written
notification or such longer period of time as the Executive Officers may agree
in writing. Regeneron’s Executive Officer shall have the deciding vote over all
matters referred to the Executive Officers by the JRC, other than (i) matters
related to the commercial reasonableness of the budget for the Initial
Development Plan for a Product Candidate which shall be resolved in accordance
with Section 13.1 below should the Executive Officers fail to
resolve such matter, (ii) decisions concerning whether Sanofi shall perform any
activities under the Discovery Program, which shall require a joint decision of
both Parties’ Executive Officers, (iii) any decision of the Executive Officers
pursuant to Section 2.4(d), and (iv) any decision of the Executive
Officers pursuant to Section 4.4. 

     

              3.4 Obligations of the Parties and their
Affiliates. The Parties
shall cause their respective designees on the JRC and their respective Executive
Officers to take the actions and make the decisions provided herein to be taken
and made by such respective designees and Executive Officers in the manner and
within the applicable time periods provided herein.

    PAYMENTS 

     

              4.1 Upfront Payment; Reimbursement Payments for
Manufacturing Expansion.
Within five (5) Business Days of the Original Agreement Effective Date, Sanofi
paid to Regeneron a non-refundable, non-creditable amount of US $85,000,000 as
consideration for access to Regeneron’s research capabilities and suite of
discovery technologies and the co-exclusive (with Regeneron) rights granted to
Sanofi hereunder during the Term. Regeneron plans to expand its facilities in
Rensselaer, New York (the “Expansion
Plans”) to help provide an adequate and timely supply of Formulated Bulk
Product for Clinical Supply Requirements (as those terms are defined in the
License Agreement) of Licensed Products. The Parties have agreed on the general
description, plan and budget of the Expansion Plans as set forth in Schedule 7.
Sanofi shall reimburse Regeneron for up to US$30,000,000 of costs incurred by
Regeneron to implement the Expansion Plans (the “Maximum Reimbursable Amount”). Within forty-five (45) days following the
end of each calendar quarter, until Regeneron has been reimbursed for the
Maximum Reimbursable Amount under this Section 4.1, Regeneron shall provide to Sanofi a detailed
report of the costs incurred by it in such calendar quarter to implement the
Expansion Plans, together with an invoice therefor. Sanofi shall reimburse
Regeneron for all costs set forth in such report and invoice within thirty (30)
days after its receipt thereof. Regeneron shall not be entitled to include
depreciation for equipment and other items included in the Expansion Plan as
Development Costs (as defined in the License Agreement) under the License
Agreement to the extent Sanofi has reimbursed Regeneron for such equipment and
other items pursuant to this Section 4.1, and shall provide evidence of the same.
Regeneron may only use the production suites identified in Schedule 7 to
manufacture products other than Licensed Products if the production of such
other products does not interfere with the production of Formulated Bulk Product
for Clinical Supply Requirements (as those terms are defined in the License
Agreement) of Licensed Products.

     

    22 

     

    

    
    


              4.2 Discovery Program Costs. Commencing on the Original Agreement
Effective Date and continuing during the term of the Discovery Program, Sanofi
shall be responsible for paying one hundred percent (100%) of all Discovery
Program Costs, including Discovery Program Costs incurred for a Product
Candidate until the anticipated IND filing date for such Product Candidate,
regardless of whether Sanofi exercises its Opt-In Rights in accordance with
Section 5.1; provided that, except as set forth below and in
Section 4.10, the total annual Discovery Program Costs to
be paid by Sanofi in each of the first ten (10) years of the Discovery Program
(the “Maximum Annual Discovery Program
Costs”) shall not exceed
the following amounts (as calculated for each Contract Year): 

     

    
      	Contract Year	    
    	Maximum Annual Discovery Program Costs
	1 (ending December 31, 2008)	
            	US $75,000,000
	2	
            	US $100,000,000
	3	
            	US $160,000,000
	4	
            	US $160,000,000
	5	
            	US $160,000,000
	6	
            	US $160,000,000
	7	
            	US $160,000,000
	8	
            	US $160,000,000
	9	
            	US $160,000,000
	10 (ending December 31, 2017)	
            	US
$160,000,000


    


    In the event that the
Discovery Program Costs incurred in any Contract Year are less than the Maximum
Annual Discovery Program Costs for such Contract Year, the amount of such
shortfall up to ten percent (10%) of the Maximum Annual Discovery Program Costs
stated immediately above for each Contract Year may be carried over to the
ensuing Contract Year and added to the Maximum Annual Discovery Program Costs
for such ensuing Contract Year except for any such shortfall at the end of
Contract Year 10, such that Regeneron’s right to carry over any shortfall shall
not be applicable into or during the Tail Period. At least sixty (60) days prior
to the end of each Contract Year, Regeneron shall notify Sanofi if it reasonably
believes that the total Discovery Program Costs for such Contract Year will be
less than the Maximum Annual Discovery Program Costs for such Contract Year and
whether Regeneron intends to apply such shortfall amount to the Discovery
Program Costs for the ensuing Contract Year.

     

    To the extent that
Sanofi performs any activities under the Discovery Program, it shall do so at
its sole cost and expense and such costs and expenses shall not be treated as
Discovery Program Costs for purposes of calculating the Maximum Annual Discovery
Program Costs unless the JRC expressly requests Sanofi to perform any such
activities, in which case the mutually agreed upon costs directly related to
such activities shall be included in the calculation of the Maximum Annual
Discovery Program Costs. The Parties acknowledge that payments made by Sanofi
pursuant to this Section 4.2 are
being made as research and development expenses, as defined in the U.S. Internal
Revenue Code Section 41, and agree that any and all credits or deductions to
which either party may be entitled on account of research performed pursuant to
such payments shall be allocated to Sanofi to the extent of such
payments.

              4.3 Reports and Discovery Program Cost
Payments. Within
forty-five (45) days following the end of each calendar quarter, Regeneron shall
deliver electronically to Sanofi a written report setting forth in reasonable
detail the Discovery Program Costs incurred by Regeneron in such calendar
quarter along with an invoice therefore. Sanofi shall reimburse Regeneron for
all undisputed Discovery Program Costs set forth in each report within thirty
(30) days after its receipt thereof. Any disputed, unpaid Discovery Program
Costs that are determined to be due and payable to Regeneron under this
Agreement shall be paid with the Default Interest Rate. 

     

              4.4 **************** Opt-in
Payment. (a) In the event
that Sanofi exercises its Opt-In Rights in accordance with Section 5.1 with regard ***************, then

Notice for such a Product Candidate whether it, in good faith, agrees or
disagrees with Regeneron, including any supporting information supporting its
belief. In the event of a disagreement between the Parties as to
*************************, the matter shall be referred to the Executive
Officers for a joint decision in accordance with Section 3.3. In the event the Executive Officers are unable to reach
agreement with respect to the matter in accordance with Section 3.3, then the dispute shall be referred to an
independent Third Party expert (the “Expert”). The Parties shall alternate having the
right to select an Expert to resolve disputes in accordance with this
Section 4.4, with Sanofi selecting the Expert for the
first such dispute and neither Party selecting an Expert that was used
previously by either Party without the written consent of the other Party. Each
Expert shall be selected by the applicable Party within thirty (30) days of the
end of the thirty (30) day period referred to in Section 3.3. Each Expert must be a person selected in
good faith who is knowledgeable in the field of Antibodies, possessing senior
executive experience in the biotechnology or pharmaceutical industry, and has no
known prior, current, or planned future association (by contract, employment, or
otherwise) with the selecting Party, any of its Affiliates, or any officer,
director, or employee of such Party or any of its Affiliates. The Parties will
both enter into a consulting agreement with each Expert and will share equally
in all fees charged by each Expert. Each Expert shall be instructed in the
consulting agreement to make his decision as to ********************* within two
(2) weeks of his selection. The Expert’s decision shall be final and binding
upon the Parties. For the avoidance of doubt, any dispute under this
Section 4.4(a) shall not delay the development of the
applicable Licensed Product. 

     

                   (b) ***********************************.

     

              4.5 Royalty Payments for Royalty
Products. If either Party,
or its Affiliate or licensee successfully develops and commercializes a Royalty
Product, then the commercializing Party
shall pay to the non-commercializing Party, within sixty (60) days following the
end of each calendar quarter, the following royalties on the aggregate Net Sales
of such, respective Royalty Products during the Royalty Term:
*********************************. 

     

    24 

     

    

    
    


    In the event that any
Royalty Product requires a sub-license to Sanofi Patent Rights or Regeneron
Patent Rights, as applicable, and such sub-license is granted under this
Agreement, then any financial remuneration that the licensing Party is required
to pay to a Third Party for its license from the Third Party shall be considered
a pass-through cost to be borne by the Party developing and/or commercializing
the Royalty Product.

     

              4.6 Royalty Term and Reporting. The royalties payable under Sections 4.5 (i), 4.5(iii), and 4.5(v) of this Agreement shall each be paid for the
period of time, as determined on a Royalty Product-by-Royalty Product and
country-by-country basis, commencing on the Effective Date and ending on the
later to occur of (a) ****************, (b) the expiration of the last to expire
Valid Claim of the Licensed Sanofi Target IP or Regeneron Target IP, as the case
may be. The royalties payable under Sections 4.5 (ii), 4.5 (iv), 4.5(vi), and 4.5(vii) of this Agreement shall each be paid on a
Royalty Product-by-Royalty Product and country-by-country basis, commencing on
the Effective Date and ending on the expiration of the last to expire Valid
Claim of the licensed Sanofi Target IP (the applicable period of time during
which royalties are payable pursuant to this sentence and the preceding sentence
being referred to as the applicable “Royalty Term”). During the applicable Royalty Term, the
Party owing royalties shall deliver to the other Party with each royalty payment
a report detailing in reasonable detail the information necessary to calculate
the royalty payments due under this Agreement for such calendar quarter,
including the following information, specified on a Royalty Product-by-Royalty
Product and country-by-country basis: (a) total gross invoiced amount from sales
of each Royalty Product by a Party, its Affiliates and sublicensees; (b) all
relevant deductions from gross invoiced amounts to calculate Net Sales; (c) Net
Sales; and (d) royalties payable.

     

              4.7 Payment Method and Currency. All payments under this Agreement shall be
made by bank wire transfer in immediately available funds to an account
designated by the Party to which such payments are due. All sums due under this
Agreement shall be payable in United States Dollars. In those cases where the
amount due in United States Dollars is calculated based upon one or more
currencies other than United States Dollars, such amounts shall be converted to
United States Dollars using the average of the buying and selling exchange rate
for conversion of the applicable foreign currency into United States Dollars,
using the spot rates (the “Closing Mid-Point Rates” found in the “Dollar spot
forward against the Dollar” table published by The Financial Times, or any other publication as agreed to by the Parties) from the last
Business Day of the preceding month.

     

              4.8 Late Payments. All late payments made under this Agreement
(including payments made pursuant to Sections 4.4 and 4.5 above), shall earn interest, to the extent
permitted by applicable Law, from the date due until paid at a rate equal to the
thirty (30) day London Inter-Bank Offering Rate (LIBOR) U.S. Dollars, as quoted
in The Wall Street Journal (U.S., Eastern Edition) effective for the
date on which the payment was due, plus two percent (2%) (such sum being referred to as the
“Default Interest Rate”). 

     

    25 

     

    

    
    


              4.9 Taxes. Except as set forth in Section 4.1, any withholding or other taxes that a Party
is required by Law to withhold or pay on behalf of the other Party, with respect
to any payments to such other Party hereunder, shall be deducted from such
payments and paid to the appropriate tax authority contemporaneously with the
remittance to such other Party; provided, however, that the remitting Party shall furnish the
other Party with proper evidence, including any self-reporting documentation, of
the taxes so paid. Each Party shall cooperate with the other and furnish the
other Party with appropriate documents to secure application of the most
favorable rate of withholding tax under applicable Law (or exemption from such
withholding tax payments, as applicable).

     

              4.10 Special Adjustment. If *********************, the Maximum Annual
Discovery Program Costs set forth in Section 4.1 shall be reduced to US$120,000,000 for each
of Contract Years 7, 8, 9, and 10 (the “Special Adjustment”). Notwithstanding the foregoing,
**************************. If Sanofi exercises its option for the Special
Adjustment following the occurrence of the conditions set forth above, then
Regeneron shall have the right (the “Catch Up Right”), in its sole discretion, to fund up to
US$40,000,000 of Discovery Program Costs on its own for each of the remaining
Contract Years through the Discovery Expiration Date (the actual aggregate
amount of such Discovery Program Costs funded by Regeneron on its own during
Contract Years 7, 8, 9, and 10 being referred to as the “Catch-Up Amount”). Regeneron shall have sixty (60) days from
the date of the Special Adjustment to exercise the Catch Up Right and shall
notify Sanofi promptly in writing of such exercise. Regeneron shall provide Sanofi within sixty
(60) days of the beginning of each subsequent Contract Year with a written
report setting forth in reasonable detail the calculation of the Catch-Up
Amount. If Regeneron exercises this Catch Up Right, then ****************, then
Sanofi shall be required to make a payment to Regeneron equal to the Catch-Up
Amount within forty-five (45) days after receipt of a written report setting
forth in reasonable detail the calculation of the Catch-Up Amount. Effective
upon the occurrence of the Special Adjustment, unless Regeneron exercises the
Catch Up Right, the annual Collaboration Objectives shall be adjusted as
follows: ***********************************.

    OPT-IN RIGHTS TO LICENSE PRODUCT
CANDIDATES 

     

              5.1 Opt-In Rights to License Product
Candidates. Subject to the
penultimate sentence of this Section 5.1 and the other terms of this Agreement, Sanofi
shall have the exclusive right during the term of the Discovery Program to elect
to jointly (with Regeneron) develop and commercialize each Product Candidate as
set forth below, under the terms and conditions set forth in the License and
Collaboration Agreement (the “Opt-In
Rights”). While the Opt-In Rights are in effect with respect to an
Antibody from the Discovery Program, including a MTC in the Discovery Program,
Regeneron will not grant to any Third Party rights to any such Antibody. The
Opt-In Rights will expire and Sanofi will no longer have any rights or licenses
to any Antibodies, including MTCs, under this Agreement upon the expiration or
earlier termination of the Discovery Program. After the first ten (10) years of
the Discovery Program, the Opt-In Rights shall remain in effect during the Tail
Period solely with respect to Lead Candidates and other Antibodies and MTCs
against any applicable Program Targets properly identified by Sanofi in its
notice to extend the Discovery Program through the Tail Period provided under Section 2.9. For the avoidance of doubt, Sanofi shall
have no Opt-In Rights to Excluded Candidates owned or licensed by Regeneron or
its Affiliates. 

     

    26 

     

    

    
    


              5.2 Process for Opt-In Rights. *************************. 

     

              5.3 Initial Development Plan. Within thirty (30) days after Sanofi’s
receipt of the Opt-In Report, the Parties shall jointly commence, and thereafter
as promptly as practicable complete, preparation of a plan and budget for the
planned development activities for such Product Candidate through the completion
of the Phase I Clinical Trial (the “Initial Development Plan”), the final budget included in which shall
be subject to Sanofi’s written approval, not to be unreasonably withheld or
delayed; provided, however, that (i) the Parties shall not be required
to continue or complete such preparation if the Opt-In Period for such Product
Candidate has expired without Sanofi having timely exercised its Opt-In Rights
with respect thereto or Sanofi shall have otherwise advised Regeneron in writing
that it will not exercise its Opt-In Rights with respect to such Product
Candidate and (ii) if the Parties are unable to agree on a final budget the
matter shall first be referred to the Executive Officers in accordance with
Section 3.3(b) above, and if such Executive Officers are
unable to resolve such matter, it shall be submitted to binding arbitration to
be conducted in accordance with Section 13.1 below. If Sanofi properly exercises its
Opt-In Rights with respect to a Product Candidate, such Product Candidate shall
be developed in accordance with the Initial Development Plan until the Parties
agree to the “Global Development Plan” as such term is defined in the License and
Collaboration Agreement. 

     

              5.4 Opt-In Exercise. Sanofi may exercise its Opt-In Rights under
this Agreement and license a Product Candidate under the License and
Collaboration Agreement by delivering to Regeneron a written notice of exercise
in the form annexed hereto as Exhibit A (an “Opt-In Notice”) on or before
******************************. 

     

              5.5 Dll4 and REGN 88. Sanofi exercised its Opt-In Rights to REGN
88 as of the Original Agreement Effective Date and was deemed to have exercised
its Opt-In Rights with respect to the MTC against Delta-like ligand 4 (Dll4) as
of the Original Agreement Effective Date.

     

              5.6 Refused Candidates. If Sanofi does not provide Regeneron with an
Opt-In Notice within the Opt-In Period with respect to a particular Product
Candidate, or Sanofi notifies Regeneron that it will not exercise Opt-In Rights
with respect to the Product Candidate, then the following shall
apply:

     

                   (i) Refused Candidate. The Opt-In Rights shall expire with respect
to that Product Candidate (a “Refused Candidate”). All licenses granted in Section 2.10 shall automatically expire with respect to
each Product Candidate upon such Product Candidate becoming a Refused Candidate.
Following such time as a Product Candidate becomes a Refused Candidate, except
as set forth below, the applicable Target shall no longer be deemed a Program
Target and shall be removed from the Target List and Sanofi shall no longer have
any rights to any Antibodies, including MTCs, against such Target under this
Agreement. Sanofi shall have a one-time right within four (4) weeks of the date
a Product Candidate becomes a Refused Candidate to designate the Target for such Refused Candidate as one of
its Sanofi Targets, otherwise it shall be considered an Excluded
Target.

     

    27 

     

    

    
    


                   (ii) Regeneron Rights. Regeneron may continue to develop and
commercialize (on its own or with one or more Third Parties) any Refused
Candidate without restriction outside the Discovery Program and this Agreement,
unless the Refused Candidate is a Competing Refused Candidate, in which case,
Section 2.8(b)(ii) shall apply. In addition, unless Sanofi has
exercised its right under Section 5.6(i) to designate the applicable Target for a
Refused Candidate as one of its Sanofi Targets, then Regeneron may continue to
develop and commercialize (on its own or with one or more Third Parties) any
MTCs or other Antibodies against such Target and may practice and use any
Regeneron Intellectual Property, including, without limitation, the Mice, in
connection with such activities. If Sanofi has designated the applicable Target
for the Refused Candidate as a Sanofi Target pursuant to Section 5.6(i), then all Antibodies (including MTCs) against
such Target that were generated under the Discovery Program other than the
Refused Candidate shall remain part of the Discovery Program. 

     

                   (iii) Sanofi Rights. Neither Sanofi nor its Affiliates, either
directly or through any Third Party, may develop or commercialize an Antibody
that is against the Target of a Refused Candidate

              6.1 Ownership of Newly Created Intellectual
Property. 

     

                   (a) Each Party shall exclusively own all intellectual property (including,
without limitation, Know-How, Patents and Patent Applications and copyrights)
discovered, invented, authored or otherwise created solely by such Party, its
employees, agents and consultants under the Discovery Program (“Sole Inventions”). Sole Inventions made solely by Sanofi, its
employees, agents and consultants are referred to herein as “Sanofi Sole Inventions.” Sole Inventions made solely by Regeneron,
its employees, agents and consultants are referred to herein as “Regeneron Sole Inventions.” The Parties agree that nothing in this
Agreement, and no use by a Party of the other Party’s Intellectual Property
pursuant to this Agreement, shall vest in a Party any right, title or interest
in or to the other Party’s Intellectual Property, other than the license rights
expressly granted hereunder. 

     

                   (b) The Parties shall jointly own all intellectual property (including,
without limitation, Know-How, Patents and Patent Applications and copyrights)
discovered, invented, authored or otherwise created under the Discovery Programs
that is invented or authored jointly by an individual or individuals having an
obligation to assign such intellectual property to Sanofi (or for which
ownership vests in Sanofi by operation of law), on the one hand, and an
individual or individuals having an obligation to assign such intellectual
property to Regeneron (or for which
ownership vests in Regeneron by operation of law), on the other hand, on the
basis of each Party having an undivided interest in the whole (“Joint Inventions”). 

     

    28 

     

    

    
    

     

                   (c) Notwithstanding the foregoing in Section 6.1(b), (i) for purposes of
determining whether a patentable invention is a Sanofi Sole Invention, a
Regeneron Sole Invention or a Joint Invention, questions of inventorship shall
be resolved in accordance with United States patent laws, as determined, if
necessary, by an independent third party, (ii) for purposes of determining
whether a copyrighted work is a Sanofi Sole Invention, a Regeneron Sole
Invention or a Joint Invention, questions of copyright authorship shall be
resolved in accordance with United States copyright laws, and (iii) for purposes
of determining whether Know-How (other than copyrighted work and Patent
Applications) is a Sanofi Sole Invention, a Regeneron Sole Invention or a Joint
Invention, questions of authorship or inventorship shall be resolved in
accordance with the laws of the State of New York, United States. 

     

                   (d) To the extent that any right, title or interest in or to any intellectual
property discovered, invented, authored or otherwise created under this
Agreement vests in a Party or its Affiliate, by operation of Law or otherwise,
in a manner contrary to the agreed upon ownership as set forth in this
Agreement, such Party (or its Affiliate) shall, and hereby does, irrevocably
assign to the other Party any and all such right, title and interest in and to
such intellectual property to the other Party without the need for any further
action by any Party. 

     

                   (e) The Parties hereby agree that each Party’s use of the Joint Inventions
shall be governed by the terms and conditions of this Agreement including the
following: each Party’s interest in the Joint Inventions may be sublicensed to
Third Parties, and any ownership rights therein transferred, in whole or in
part, by each Party without consent of the other Party (unless otherwise
prohibited by this Agreement or the License and Collaboration Agreement);
provided that (i) each of the Parties acknowledges
that it receives no rights to any Intellectual Property of the other Party
underlying or necessary for the use of any Joint Invention, except as otherwise
set forth herein or in the License and Collaboration Agreement, (ii) each Party
agrees not to transfer any of its ownership interest in any of the Joint
Inventions without securing the transferee’s written agreement to be bound by
the terms of this Section 6.1(e), (iii) during the Discovery Program, each
Party agrees not to license its interest in any Joint Invention with the right
to use such Joint Invention for developing, manufacturing or commercializing
antibodies (except for developing, manufacturing or commercializing a Party’s
Antibodies that may be included in the exclusions described in Section 2.8 (b) of the Agreement), and (iv) nothing in this
Article 6 shall relieve a Party or its Affiliates of
their obligations under Article 9 with respect to Confidential Information
provided by the other Party or such other Party’s Affiliates. Neither Party
hereto shall have the obligation to account to the other Party for any revenues
or profits obtained from any transfer of its interest in, or its use, sublicense
or other exploitation of, the Joint Inventions outside the scope of the
Discovery Program. Each of the Parties (or its Affiliate), as joint owner of the
Joint Inventions, agrees to cooperate with any enforcement actions brought by
the other joint owner(s) against any Third Parties, and further agrees not to
grant any licenses to any such Third Parties against which such enforcement
actions are brought during the time of such dispute, without the prior written
consent of the other joint owner(s), such consent not to be unreasonably
withheld. The provisions governing Joint Inventions set forth in this
Section 6.1(e) shall survive the expiration or termination
of this Agreement.

              6.2 Prosecution and Maintenance of Patent
Rights. 

     

                   (a) Subject to the terms of the License and Collaboration Agreement with
respect to Licensed Products, Regeneron shall prepare, file, prosecute and
maintain Patents and Patent Applications (as applicable) included in the
Regeneron Patent Rights and Regeneron shall confer with and keep Sanofi
reasonably informed regarding the status of such activities to the extent they
are Product Patent Rights. *********************************.

     

                   (b) With respect to any Joint Patent Rights, the Parties shall consult with
each other regarding the filing, prosecution and maintenance of any Patents and
Patent Applications, and responsibility for such activities shall be the
obligation of Regeneron. Regeneron shall undertake such filings, prosecutions
and maintenance in the names of both Parties as co-owners
***************************************.

     

                   (c) The Parties shall have the following obligations with respect to the
filing, prosecution and maintenance of any Joint Patent Rights, as well as any
Product Patent Rights: (i) the prosecuting Party (the “Prosecuting Party”) shall provide the other Party (the
“Non-Prosecuting Party”) with notice and a copy of a substantially
completed draft of any Patent Application at least thirty (30) days prior to the
filing of any such Patent Application by the Prosecuting Party and incorporate
all reasonable comments provided by the Non-Prosecuting Party within such thirty
(30) day period unless the Prosecuting Party reasonably believes that such
comments will adversely affect the scope or validity of the Patent Application
or resulting Patent (it being understood that the Parties will discuss any
points of disagreement and work to resolve disagreements during this thirty (30)
day period); (ii) the Prosecuting Party shall notify the Non-Prosecuting Party
prior to its filing of a Patent Application; (iii) the Prosecuting Party shall
consult with the Non-Prosecuting Party promptly following the filing of the
Patent Application to mutually determine in which countries it shall file
convention Patent Applications; (iv) the Prosecuting Party shall provide the
Non-Prosecuting Party promptly with copies of all material communications
received from or filed in patent offices with respect to such applications and
incorporate all reasonable comments provided by the Non-Prosecuting Party,
unless the Prosecuting Party reasonably believes that such comments will
adversely affect the validity or scope of the Patent Application or resulting
Patent for both Parties; and (v) the Prosecuting Party shall provide the
Non-Prosecuting Party a reasonable time prior to taking or failing to take
action that would affect the scope or validity of rights under any Patent
Applications or Patents, but in no event less than sixty (60) days prior to the
next deadline for any action that may be taken with the applicable patent
office, (including but not limited to substantially narrowing or canceling any
claim without reserving the right to file a continuing or divisional Patent
Application, abandoning any Patent or not filing or perfecting the filing of any
Patent Application in any country), with notice of such proposed action or
inaction so that the Non-Prosecuting Party has a reasonable opportunity to
review and make comments, and take such actions as may be appropriate in the
circumstances, including assuming the Prosecuting Party’s responsibility for
filing, prosecution and maintenance of any such Product Patent Right or Joint
Patent Right and becoming the Prosecuting Party. With respect to Joint
Inventions, it is understood that the Prosecuting Party and Non-Prosecuting
Party shall use all reasonable efforts to reach agreement on all material
filings and amendments and no such material filings or amendments shall be made
by the Non-Prosecuting Party without the prior written agreement of the
Non-Prosecuting Party, such agreement not to be unreasonably withheld or
delayed. In addition, in the event that the Prosecuting Party materially
breaches the foregoing obligations and such material breach is not cured within
thirty (30) days of a written notice from the Non-Prosecuting Party describing
such breach in reasonable detail, or in the event that the Prosecuting Party
fails to undertake the filing of a Patent Application within the earlier of (i)
ninety (90) days of a written request by the Non-Prosecuting Party to do so, and
(ii) sixty (60) days prior to the anticipated filing date, the Non-Prosecuting
Party may assume the Prosecuting Party’s responsibility for filing, prosecution
and maintenance of any such Product Patent Right and will thereafter be deemed
the Prosecuting Party for purposes hereof. Notwithstanding the foregoing, the
Prosecuting Party may withdraw from or abandon any Patent or Patent Application
on thirty (30) days’ prior notice to the Non-Prosecuting Party (provided that such notice shall be given no later than
sixty (60) days prior to the next deadline for any action that may be taken with
respect to such Patent or Patent Application with the applicable patent office),
providing the Non-Prosecuting Party a free-of-charge option to assume the
prosecution or maintenance thereof. The Parties will file and prosecute Patent
Applications described in this Section 6.2(a) in the list of countries set forth in
Exhibit B, unless otherwise agreed upon by the
Parties.

     

    30 

     

    

    
    


                   (d) All costs incurred in the filing, prosecution and maintenance of any
Joint Patent Rights and Product Patent Rights and in performing freedom to
operate analyses on Program Targets or Lead Candidates shall be shared equally
by the Parties.

     

                   (e) Each Party shall have the right to invoke the Cooperative Research and
Technology Enhancement Act of 2004, 35 U.S.C. 103(c)(2)-(c)(3) (the "CREATE
Act") with respect to Joint Inventions, without the prior written consent of the
other Party. In the event that a Party intends to invoke the CREATE Act, as
permitted by the preceding sentence, it shall notify the other Party and the
Parties shall reasonably cooperate and coordinate their activities with respect
to any submissions, filings or other activities in support thereof. The Parties
acknowledge and agree that this Agreement is a "joint research agreement" as
defined in the CREATE Act. For the avoidance of doubt, nothing in this
Section 6.2(e) shall amend or modify the determination of
ownership of intellectual property as set forth in Section 6.1. 

     

              6.3 Third Party Claims. In the normal course of business, Regeneron
shall carry out patent searches in relation to the Program Targets, Lead
Candidates, and Product Candidates, as well as the technologies used to
discover, develop and commercialize any of the foregoing, and will disclose,
along with any analysis, to Sanofi’s counsel any conflict or likely conflict of
which Regeneron is aware with respect to the Patent Rights of any Third Party
with respect to any such Program Targets, Lead Candidates and Product Candidates
prior to selection to enter IND Preparation. If either Party or its Affiliates
shall learn of a Third Party claim that the activities under the Discovery
Program infringe or otherwise violate the intellectual property rights of any
Third Party in the Territory, then such Party shall promptly notify the other
Party in writing of this claim, assertion or certification. As soon as
reasonably practical after the receipt of such notice, the Parties shall cause
their respective legal counsel to meet to confer on such allegation of
infringement. In particular, with regard to issues related to freedom to operate
concerning Targets pursued under this Agreement, the Parties shall conduct and
maintain ongoing and regular communications between their legal/intellectual
property departments.

    ARTICLE 7 

     

    BOOKS, RECORDS AND INSPECTIONS; AUDITS AND
ADJUSTMENTS 

     

              7.1 Books and Records. Each Party shall keep proper books of record
and account in which full, true and correct entries (in conformity with GAAP)
shall be made for the purpose of determining the amounts payable or owed
pursuant to this Agreement. Each Party shall permit auditors, as provided in
Section 7.2, to visit and inspect, during regular
business hours and under the guidance of its employees, the books of record and
account of such Party to the extent relating to this Agreement and discuss its
affairs, finances and accounts to the extent relating to this Agreement.


     

              7.2 Audits and Adjustments.

     

                   (a) Each Party shall have the right, upon no less than thirty (30) days’
advance written notice and at such reasonable times and intervals and to such
reasonable extent as the Party shall request, not more than once during any
Contract Year, to have the books and records of the other Party to the extent
relating to this Agreement for the preceding two (2) years audited by an
independent “Big Four” (or equivalent) accounting firm of its choosing under
reasonable, appropriate confidentiality provisions, for the sole purpose of
verifying the accuracy of all financial, accounting and numerical information
and calculations provided, and payments made, under this Agreement; provided that no period may be subjected to audit more
than one (1) time unless a material discrepancy is found in any such audit of
such period, in which case additional audits of such period may be conducted
until no material discrepancies are found. 

     

                   (b) The results of any such audit shall be delivered in writing to each Party
and shall be final and binding upon the Parties, unless disputed by a Party
within ninety (90) days of delivery. If a Party over billed or underpaid an
amount due under this Agreement resulting in a cumulative discrepancy during any
year of more than *****************, it shall also reimburse the other Party for
the costs of such audit (with the cost of the audit to be paid by the Party
initiating the audit in all other cases). Such accountants shall not reveal to
the Party requesting the audit the details of its review, except for the
findings of such review and such information as is required to be disclosed
under this Agreement, and shall be subject to the confidentiality provisions
contained in Article 9. 

     

                   (c) If any examination or audit of the records described above discloses an
over billing or underpayment of amounts due hereunder, then unless the result of
the audit is contested pursuant to Section 7.2(b) above, the Party that overbilled or underpaid
shall pay the same (plus interest thereon at the Default Interest Rate from the
date of such over billing or underpayment through the date of payment of the
amount required to be paid pursuant to this Section 7.2(c)) to the Party entitled thereto within thirty
(30) days after receipt of the written results of such audit pursuant to this
Section 7.2. 

     

                   (d) Disputes. Any disputes with respect to the results of
any audit conducted under Section 7.2 above shall be resolved by binding
arbitration in accordance with Section 13.1 below.

     

    
                7.3 IAS/IFRS/GAAP. Except as otherwise provided herein, all
costs and expenses and other financial determinations with respect to this
Agreement shall be determined in accordance with IAS/IFRS, and for the US, if
desired, GAAP, as generally and consistently applied.

jurisdiction of incorporation; (b) it has full corporate power and authority and
has taken all corporate action necessary to enter into and perform this

Litigation. Each Party
represents and warrants to the other Party that, as of the Effective Date, there
is no claim, announced investigation, suit, action or proceeding pending or, to

could reasonably be expected to (a) materially impair the ability of such Party
to perform any of its obligations under this Agreement or (b) prevent or
materially delay or alter the consummation of any or all of the transactions
contemplated hereby. During the term of the Discovery Program, each Party shall
promptly notify the other Party in writing upon learning of any of the

Warranties and Covenants.
Regeneron additionally represents and warrants to Sanofi that, as of the
Effective Date: 

     

                   (a) Regeneron owns or has a valid license to all Regeneron Patent Rights in
existence as of the Effective Date; 

     

                   (b) Regeneron has the right and authority to grant the rights (including the
Opt-In Rights) granted pursuant to the terms and conditions of this Agreement
and Regeneron has not granted, and will not grant during the term of this
Agreement, any rights that would be inconsistent with or in conflict with or in
derogation of the rights granted herein; 

     

                   (c) there is no pending litigation of which Regeneron has received notice or
is otherwise aware that alleges that any of Regeneron’s activities relating to

the intellectual property rights of any Third Party (nor has it received any
written communication threatening such litigation);

     

    33 

     

    

    
    


                   (d) to Regeneron’s knowledge, no litigation has been otherwise threatened
which alleges that any of its activities relating to the Mice or the Regeneron
Intellectual Property have violated or would violate, any intellectual property
rights of any Third Party; 

     

                   (e) to Regeneron’s knowledge, after due inquiry, the use of the Mice and the
Regeneron Intellectual Property generally in the Discovery Program (but not with
respect to a specific MTC or Target) does not and will not infringe or otherwise
violate any valid Patent or provisional rights to applications or other
intellectual property of any Third Party claiming genetically modified mice or
the use thereof to make antibodies; 

     

                   (f) neither the development or reproduction of the Mice nor the conception,
development and reduction to practice of any Regeneron Intellectual Property

misappropriation of trade secrets or other rights of any Person; 

     

                   (g) to Regeneron’s knowledge, the issued Patents included in the Regeneron
Intellectual Property existing as of the Effective Date are not invalid or

                   (h) Regeneron has not received any written notice of any threatened claims or
litigation seeking to invalidate or otherwise challenge the Regeneron Patent
Rights or Regeneron’s rights therein, and, to Regeneron’s knowledge, none of the
Regeneron Patent Rights are subject to any pending re-examination, opposition,
interference or litigation proceedings; and

     

                   (i) neither Regeneron nor any of its Affiliates shall transfer ownership,
assign ownership, grant a security interest in or otherwise encumber any of its
rights in, to or under any Regeneron Intellectual Property in a way that will
impair Sanofi’s rights or Regeneron ability to perform its obligations under
this Agreement.

    ARTICLE 9 

     

    CONFIDENTIALITY 

     

              9.1 Confidential Information. During the term of this Agreement and for a
period of five (5) years thereafter, each Party (in such capacity, the
“Receiving Party”) shall keep confidential, and other than as
provided herein or in the License and Collaboration Agreement, shall not use or
disclose, directly or indirectly, any and all trade secrets or other proprietary
information, including, without limitation, any proprietary data, inventions,
documents, ideas, information, discoveries, or materials, owned, developed, or
possessed by the other Party (in such capacity, the “Disclosing Party”), whether in tangible or intangible form,
the confidentiality of which the Disclosing Party takes reasonable measures to
protect, including but not limited to Regeneron Know-How and Sanofi Know-How
disclosed by the Disclosing Party under this Agreement (the “Confidential Information”). For purposes of this Agreement, all
confidential information disclosed by Regeneron under the terms of the
confidentiality agreements between Sanofi Parent and Regeneron dated February 1,
2007 and October 23, 2007 is hereby deemed Confidential Information of
Regeneron. Each of Sanofi and Regeneron covenants that neither it nor any of its
respective Affiliates shall disclose any Confidential Information of the other
Party to any Third Party except to its employees, agents, consultants or any
other Person under its authorization; provided such employees, agents, consultants or other
Persons are subject in writing to confidentiality obligations applicable to the
Disclosing Party’s Confidential Information no less strict than those set forth
herein. 

     

                   (a) Notwithstanding the
foregoing, Confidential Information shall not be deemed to include information
and materials (and such information and materials shall not be considered
Confidential Information under this Agreement) to the extent that it can be
established by written documentation by the Receiving Party that such
information or material is: (i) already in the public domain as of the Effective
Date or becomes publicly known through no act, omission or fault of the
Receiving Party or any Person to whom the Receiving Party provided such
information; (ii) is or was already in the possession of the Receiving Party at
the time of disclosure by the Disclosing Party; (iii) is disclosed to the
Receiving Party on an unrestricted basis from a Third Party not under an
obligation of confidentiality to the Disclosing Party or any Affiliate of the
Disclosing Party with respect to such information; (iv) information that has
been independently created by the Receiving Party (or its Affiliate), as
evidenced by written or electronic documentation, without any aid, application
or use of the Disclosing Party’s Confidential Information; or (v) required by
Law to be disclosed, provided that the Receiving Party uses reasonable
efforts to give the disclosing Party advance notice of such required disclosure
in sufficient time to enable the Disclosing Party to seek confidential treatment
for such information, and provided further that the Receiving Party provides all
reasonable cooperation to assist the Disclosing Party to protect such
information and limits the disclosure to that information which is required by
Law to be disclosed.

     

                   (b) Information and other
Know-How that is discovered by Regeneron in connection with the Discovery
Program will be considered Regeneron’s Confidential Information, except to the
extent it relates to a Licensed Product, in which case it shall be Confidential
Information of both Parties, subject to the terms of the License and
Collaboration Agreement. 

     

    35 

     

    

    
    


                   (c) Specific aspects or details of Confidential Information will not be
deemed to be within the public knowledge or in the prior possession of a Person
merely because such aspects or details of the Confidential Information are
embraced by general disclosures in the public domain. In addition, any
combination of Confidential Information will not be considered in the public
knowledge or in the prior possession of either Person merely because individual
elements thereof are in the public domain or in the prior possession of a Person
unless (i) the combination and its principles are in the public knowledge or in
the prior possession of that Person and (ii) the combination is documented, in a
single contemporaneous document, as in the public knowledge or in the prior
possession of a Person. 

     

                   (d) Notwithstanding anything else in this Agreement to the contrary, each
Party hereto (and each employee, representative, or other agent of any Party)
may disclose to any and all Persons, without limitation of any kind, the Federal
income tax treatment and Federal income tax structure of any and all
transaction(s) contemplated herein and all materials of any kind (including
opinions or other tax analyses) that are or have been provided to any Party (or
to any employee, representative, or other agent of any party) relating to such
tax treatment or tax structure, provided, however, that this authorization of disclosure shall
not apply to restrictions reasonably necessary to comply with securities laws.
This authorization of disclosure is retroactively effective immediately upon
commencement of the first discussions regarding the transactions contemplated
herein, and the Parties aver and affirm that this tax disclosure authorization
has been given on a date which is no later than thirty (30) days from the first
day that any Party hereto (or any employee, representative, or other agent of
any party hereto) first made or provided a statement as to the potential tax
consequences that may result from the transactions contemplated
hereby.

     

              9.2 Injunctive Relief. The Parties hereby acknowledge and agree
that the rights of the Parties hereunder are special, unique and of
extraordinary character, and that if any Party refuses or otherwise fails to
act, or to cause its Affiliates to act, in accordance with the provisions of
this Agreement, such refusal or failure would result in irreparable injury to
the other Party, the exact amount of which would be difficult to ascertain or
estimate and the remedies at law for which would not be reasonable or adequate
compensation. Accordingly, if any Party refuses or otherwise fails to act, or to
cause its Affiliates to act, in accordance with the provisions of this
Agreement, then, in addition to any other remedy which may be available to any
damaged Party at law or in equity, such damaged Party will be entitled to seek
specific performance and injunctive relief, without posting bond or other
security, and without the necessity of proving actual or threatened damages,
which remedy such damaged party will be entitled to seek in any court of
competent jurisdiction. 

     

              9.3 Publications. If either Sanofi or Regeneron (the
“Publishing Party”) desires to publish or publicly present any
results from the Discovery Program in scientific journals, publications or
scientific presentations or otherwise, the Publishing Party shall provide the
other Party an advance final copy of any proposed publication or summary of a
proposed oral presentation relating to the information from the Discovery
Program prior to submission for publication or disclosure. Such other Party
shall have a reasonable opportunity to recommend any changes it reasonably
believes are necessary to preserve the confidentiality of its Confidential
Information and to recommend any changes it reasonably believes are necessary to
prevent any specific, material adverse effect to it as a result of the
publication or disclosure, to which the Publishing Party shall give due
consideration. If such other Party informs the Publishing Party, within thirty
(30) days of receipt (or such other period agreed to by the JRC) of an advance
copy of a proposed publication or summary of a proposed oral presentation, that
such publication in its reasonable judgment should not be published or
presented, the Publishing Party shall delay or prevent such disclosure or
publication as proposed by the other Party. In the case of patentable
inventions, the delay shall be sufficiently long to permit the timely
preparation and filing of a patent application(s) or application(s) for a
certificate of invention on the information involved. The Parties shall
establish a publication review process to ensure compliance with this Section 9.3.

     

    36 

     

    

    
    


              9.4 Disclosures Concerning this
Agreement. The Parties
will mutually agree upon the contents of a their respective press releases with
respect to the execution of this Agreement and the License and Collaboration
Agreement which shall be issued simultaneously by both Parties on the Effective
Date. Sanofi and Regeneron agree not to (and to ensure that their respective
Affiliates do not) issue any other press releases or public announcements
concerning this Agreement or any other activities contemplated hereunder without
the prior written consent of the other Party (which shall not be unreasonably
withheld or delayed), except as required by a Governmental Authority or
applicable Law (including the rules and regulations of any stock exchange or
trading market on which a Party’s (or its parent entity’s) securities are
traded); provided that the Party intending to disclose such
information shall use reasonable efforts to provide the other Party advance
notice of such required disclosure, an opportunity to review and comment on such
proposed disclosure (which comments shall be considered in good faith by the
disclosing Party) and all reasonable cooperation to assist the other Party to
protect such information and shall limit the disclosure to that information
which is required to be disclosed. Notwithstanding the foregoing, without prior
submission to or approval of the other Party, either Party may issue press
releases or public announcements which incorporate information concerning this
Agreement or any activities contemplated hereunder which information was
included in a press release or public disclosure which was previously disclosed
under the terms of this Agreement or which contains only non-material factual
information regarding this Agreement. Except as required by a Governmental
Authority or applicable Law (including the rules and regulations of any stock
exchange or trading market on which a Party’s (or its parent entity’s)
securities are traded), or in connection with the enforcement of this Agreement,
neither Party (or their respective Affiliates) shall disclose to any Third
Party, under any circumstances, any financial terms of this Agreement that have
not been previously disclosed publicly pursuant to this Article 9 without the prior written consent of the
other Party, which consent shall not be unreasonably withheld or delayed; except
for disclosures to Third Parties that are bound by obligations of
confidentiality and nonuse substantially equivalent in scope to those included
herein with a term of at least five (5) years. Each Party acknowledges that the
other Party as a publicly traded company is legally obligated to make timely
disclosures of all material events relating to its business. The Parties
acknowledge that either or both Parties may be obligated to file a copy of this
Agreement with the United States Securities and Exchange Commission or its
equivalent in the Territory. Each Party will be entitled to make such filing but
shall cooperate with one another and use reasonable efforts to obtain
confidential treatment of confidential, including trade secret, information in
accordance with applicable Law. The filing Party will provide the non-filing
Party with an advance copy of the Agreement marked to show provisions for which
the filing Party intends to seek confidential treatment and will reasonably
consider the non-filing Party’s timely comments thereon.

    ARTICLE 10 

     

    INDEMNITY 

     

              10.1 Indemnity and Insurance. 

     

                   (a) Sanofi will defend, indemnify and hold harmless Regeneron, its Affiliates
and their respective officers, directors, employees and agents (“Regeneron Indemnitees”) from and against all claims, demands,
liabilities, damages, penalties, fines and expenses, including reasonable
attorneys’ fees and costs (collectively, “Damages”), arising from or occurring as a result of a
Third Party’s claim, action, suit, judgment or settlement against a Regeneron
Indemnitee that is due to or based upon: 

     

                   (i) the negligence, recklessness, bad faith, intentional wrongful acts or
omissions of Sanofi or its Affiliates in connection with the Discovery Program,
except to the extent that Damages arise out of the negligence, recklessness, bad
faith or intentional wrongful acts, or omissions committed by Regeneron or its
Affiliates; or

     

                   (ii) material breach by Sanofi of the terms of, or the inaccuracy of any
representation or warranty made by it in, this Agreement. 

     

                   (b) Regeneron will defend, indemnify and hold harmless Sanofi, its Affiliates
and their respective officers, directors, employees and agents (“Sanofi Indemnitees”) from and against
all Damages arising from or occurring as a result of a Third Party’s claim,
action, suit, judgment or settlement against a Sanofi Indemnitee that is due to
or based upon: 

     

                   (i) the negligence, recklessness, bad faith, intentional wrongful acts or
omissions of Regeneron or its Affiliates in connection with the Discovery
Program, except to the extent that Damages arise out of the negligence,
recklessness, bad faith or intentional wrongful acts, or omissions committed by
Sanofi or its Affiliates; or

     

                   (ii) material breach by Regeneron of the terms of, or the inaccuracy of any
representation or warranty made by it in, this Agreement.

     

              10.2 Indemnity Procedure. 

     

                   (a) The Party entitled to indemnification under this Article 10 (an “Indemnified Party”) shall notify the Party potentially
responsible for such indemnification (the “Indemnifying Party”) within five (5) Business Days of becoming
aware of any claim or claims asserted or threatened in writing against the
Indemnified Party which could give rise to a right of indemnification under this
Agreement; provided, however, that the failure to give such notice shall
not relieve the Indemnifying Party of its indemnity obligation hereunder except
to the extent that such failure materially prejudices its rights hereunder.


     

    38 

     

    

    
    


                   (i) If the Indemnifying Party has acknowledged in
writing to the Indemnified Party the Indemnifying Party’s responsibility for
defending such claim, the Indemnifying Party shall have the right to
defend, at its sole cost and expense, such claim by all appropriate proceedings,
which proceedings shall be prosecuted diligently by the Indemnifying Party to a
final conclusion or settled at the discretion of the Indemnifying Party;
provided, however, that the Indemnifying Party may not enter
into any compromise or settlement unless (i) such compromise or settlement
includes as an unconditional term thereof, the giving by each claimant or
plaintiff to the Indemnified Party of a release from all liability in respect of
such claim; and (ii) the Indemnified Party consents to such compromise or
settlement, which consent shall not be withheld or delayed unless such
compromise or settlement involves (A) any admission of legal wrongdoing by the
Indemnified Party, (B) any payment by the Indemnified Party that is not
indemnified hereunder or (C) the imposition of any equitable relief against the
Indemnified Party. If the Indemnifying Party does not elect to assume control of
the defense of a claim or if a good faith and diligent defense is not being or
ceases to be materially conducted by the Indemnifying Party, the Indemnified
Party shall have the right, at the expense of the Indemnifying Party, upon at
least ten (10) Business Days’ prior written notice to the Indemnifying Party of
its intent to do so, to undertake the defense of such claim for the account of
the Indemnifying Party (with counsel reasonably selected by the Indemnified
Party and approved by the Indemnifying Party, such approval not unreasonably
withheld or delayed), provided, that the Indemnified Party shall keep the
Indemnifying Party apprised of all material developments with respect to such
claim and promptly provide the Indemnifying Party with copies of all
correspondence and documents exchanged by the Indemnified Party and the opposing
party(ies) to such litigation. The Indemnified Party may not compromise or
settle such litigation without the prior written consent of the Indemnifying
Party, such consent not to be unreasonably withheld or delayed.

     

                   (ii) The Indemnified Party may participate in, but not control, any defense or
settlement of any claim controlled by the Indemnifying Party pursuant to this
Section 10.2 and shall bear its own costs and expenses
with respect to such participation; provided, however, that the Indemnifying Party shall bear such
costs and expenses if counsel for the Indemnifying Party shall have reasonably
determined that such counsel may not properly represent both the Indemnifying
and the Indemnified Party.

     

                   (iii) The amount of any Damages for which indemnification is provided under
this Article 10 will be reduced by the insurance proceeds
received, and any other amount recovered, if any, by the Indemnified Party in
respect of any Damages.

     

                   (iv) If an Indemnified Party receives an indemnification payment pursuant to
this Article 10 and subsequently receives insurance proceeds
from its insurer with respect to the damages in respect of which such
indemnification payment(s) was made, the Indemnified Party will promptly pay to
the Indemnifying Party an amount equal to the difference (if any) between (i)
the sum of such insurance proceeds or other amounts received, and the
indemnification payment(s) received from the Indemnifying Party pursuant to this
Article 10 and (ii) the amount necessary to fully and
completely indemnify and hold harmless the Indemnified Party from and against
such Damages. However, in no event will such refund ever exceed the Indemnifying
Party’s indemnification payment(s) to the Indemnified Party under this
Article 10.

     

    39 

     

    

    
    


    ARTICLE 11 

     

    FORCE MAJEURE 

     

         Neither Party will be held liable or responsible to the other Party nor
be deemed to have defaulted under or breached this Agreement for failure or
delay in fulfilling or performing any term of this Agreement when such failure
or delay is caused by or results from causes beyond the reasonable control of
the affected Party including, without limitation, embargoes, acts of terrorism,
acts of war (whether war be declared or not), insurrections, strikes, riots,
civil commotions, or acts of God (“Force Majeure”). Such excuse from liability and
responsibility shall be effective only to the extent and duration of the
event(s) causing the failure or delay in performance and provided that the affected party has not caused such
event(s) to occur. The affected Party will notify the other Party of such Force
Majeure circumstances as soon as reasonably practical and will make every
reasonable effort to mitigate the effects of such Force Majeure circumstances.
In the event of a Force Majeure, the performance of the Party giving such
notification shall be abated and any time deadlines shall be extended for so
long as the performance is prevented by Force Majeure. In no event will any
Force Majeure extend beyond one hundred eighty (180) days. In the event of a
Force Majeure affecting satisfaction of the criteria set forth in Section 4.10,
the applicable time deadline set forth in Section 4.10 shall be extended for so
long as such Force Majeure continues, but in no event shall such extension
period exceed one hundred eighty (180) days. 

     

    ARTICLE 12 

     

    TERM AND TERMINATION 

     

              12.1 Term. The “Term” of this Agreement commenced on the Original
Agreement Effective Date and shall end upon the end of the Discovery Program,
including any Tail Period, unless this Agreement is earlier terminated in
accordance with this Article 12 in which event the Term shall end on the
effective date of such termination. 

     

              12.2 Termination For Material
Breach. Upon and subject
to the terms and conditions of this Section 12.2, this Agreement shall be terminable by a
Party in its entirety if the other Party commits a material breach of this
Agreement. Such notice of termination shall set forth in reasonable detail the
facts underlying or constituting the alleged breach (and specifically
referencing the provisions of this Agreement alleged to have been breached), and
the termination which is the subject of such notice shall be effective ninety
(90) days after the date such notice is given unless the breaching Party shall
have cured such breach within such ninety (90) day period. Notwithstanding the
foregoing, in the case of breach of a payment obligation not subject to a bona
fide dispute hereunder, the ninety (90) day period referred to in the
immediately preceding sentence shall instead be forty-five (45) days. For
purposes of this Section 12.2, the term “material breach” shall mean an
intentional, continuing (and uncured within the time period described above),
material breach by a Party as determined by binding arbitration consistent with
the provisions of Section 13.1 of this Agreement.

     

    40 

     

    

    
    


              12.3 Termination for Insolvency. Either Party shall have the right to
terminate this Agreement in its entirety if, at any time, (a) the other Party
shall file in any court or agency pursuant to any statute or regulation of any
state or country, a petition in bankruptcy or insolvency or for reorganization
or for an arrangement or for the appointment of a receiver or trustee of the
Party or of its assets, or (b) if the other Party proposes a written agreement
of composition or extension of its debts, or (c) if the other Party shall be
served with an involuntary petition against it, filed in any insolvency
proceeding, and such petition shall not be dismissed within sixty (60) days
after the filing thereof, or (d) if the other Party shall propose or be a party
to any dissolution or liquidation, or (e) if the other Party shall make an
assignment for the benefit of creditors. In the event that this Agreement is
terminated or rejected by a Party or its receiver or trustee under applicable
bankruptcy Laws due to such Party’s bankruptcy, then all rights and licenses
granted under or pursuant to this Agreement by such Party to the other Party
are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the
U.S. Bankruptcy Code and any similar Laws in any other country in the Territory,
licenses of rights to “intellectual property” as defined under Section 101(52)
of the U.S. Bankruptcy Code. The Parties agree that all intellectual property
rights licensed hereunder, including, without limitation, any Patent Rights in
any country of a Party covered by the license grants under this Agreement, are
part of the “intellectual property” as defined under Section 101(52) of the
Bankruptcy Code subject to the protections afforded the non-terminating Party
under Section 365(n) of the Bankruptcy Code, and any similar law or regulation
in any other country.

     

              12.4 Termination for Breach of
Standstill. Regeneron
shall have the unilateral right to terminate this Agreement in its entirety,
effective immediately upon written notice to Sanofi, if Sanofi or any of its
Affiliates shall have breached their obligations under any of Sections 3, 4 or 5
of the Investor Agreement (to the extent such sections of the Investor Agreement
is then in effect). Furthermore, Regeneron shall have the unilateral right to
terminate this Agreement in its entirety, effective immediately upon written
notice to Sanofi, if Sanofi or any of its Affiliates shall have (a) breached
their obligations under Section 20.16 of the Aventis Collaboration Agreement, to
the extent that such Section 20.16 remains in effect after the Effective Date,
or (b) breached its obligations under Section 5.3 of the Stock Purchase
Agreement, dated as of September 5, 2003, by and between Sanofi and Regeneron
(the “Aventis Stock Purchase Agreement”), to the extent that such Section 5.3
remains in effect after the Effective Date. Any such breach of the Investor
Agreement, the Aventis Stock Purchase Agreement or the Aventis Collaboration
Agreement, as the case may be, shall be treated as a breach of this Agreement.
Notwithstanding the foregoing and for the avoidance of doubt, Regeneron shall
not have the right to terminate this Agreement as a result of (i) a de minimus
breach of Section 3.1(a) of the Investor Agreement (to the extent such Section
3.1(a) is in effect after the Effective Date) or of Section 20.16(a) of the
Aventis Collaboration Agreement (to the extent such Section 20.16(a) remains in
effect after the Effective Date) or (ii) an inadvertent breach of Section 3.1(g)
of the Investor Agreement (to the extent such Section 3.1(g) is in effect after
the Effective Date) or an inadvertent breach of Section 20.16(g) of the Aventis
Collaboration Agreement (to the extent such Section 20.16(g) remains in effect
after the Effective Date), arising from informal discussions covering general

                   (c) the licenses granted to Regeneron under this Agreement shall
automatically terminate; 

     

                   (d) Sanofi shall be granted an exclusive, fully paid-up, non-transferable,

                   (e) Sanofi’s rights under Sections 2.16, and 2.17 shall survive; and 

     

                   (f) Sanofi shall have no further funding obligations under Section 4.2 of the Agreement.

     

    42 

     

    

    
    


              12.7 Effect of Termination by Regeneron for
Breach. In addition to the

                   (a) neither Sanofi nor
Regeneron shall be relieved of any obligations (including payment obligations)
of such Party arising prior to such expiration or termination, including,
without limitation, the payment of any non-cancelable costs and expenses
incurred as part of the Discovery Program (even if such costs and expenses arise
following termination or expiration, as the case may be); provided, however, that Sanofi shall not be obligated to pay or
reimburse Regeneron for any such costs or expenses in the event Sanofi

                   (b) the obligations of the

7.2, 10.1, 10.2, this Article 12, and Article 13) which by their nature are intended to
survive any such expiration or termination, shall survive and continue to be
enforceable;

     

                   (c) for the avoidance of
doubt, the early termination of this Agreement by either Party, and the
expiration of this Agreement shall not relieve either Party of any of its
royalty or other obligations under Article 4 with respect to any Royalty Product, for
which royalties remain payable to the other Party under this Agreement; and such
royalty provisions of Article 4 shall survive; 

     

    43

     

    

    
    


                   (d) for the avoidance of
doubt, the licenses granted in Sections 2.11(b)(3), 2.11(c), 2.12, and 2.13 shall survive the termination or expiration
of this Agreement; and

     

                   (e) such expiration or
termination and this Article 12 shall be without prejudice to any rights or
remedies a Party may have for breach of this Agreement. 

     

              12.9 Return of Confidential
Information. Subject to
either Parties’ licenses that survive termination or expiration, Confidential
Information disclosed by the Disclosing Party, including permitted copies, shall
remain the property of the Disclosing Party. Subject to the terms of the License
and Collaboration Agreement (with respect to Licensed Products), upon the
earlier to occur of (a) the termination of this Agreement or (b) the expiration
of the Discovery Program, or upon written request of the Disclosing Party, the
Receiving Party shall promptly return to the Disclosing Party or, at the
Disclosing Party’s request, destroy, all documents or other tangible materials
representing the Disclosing Party’s Confidential Information (or any designated
portion thereof); provided that one (1) copy may be maintained in the
confidential files of the Receiving Party for the purpose of complying with the
terms of this Agreement. An officer of the Receiving Party also shall certify in
writing that it has satisfied its obligations under this Section 12.9 within ten (10) days of a written request by
the Disclosing Party. 

     

              12.10 Special Damages. If Regeneron terminates this Agreement
pursuant to Section 12.2 or 12.4, then Sanofi shall pay to Regeneron, within
sixty (60) days of the termination of this Agreement, in addition to any other
amount payable by Sanofi to Regeneron under this Agreement under Laws, or
pursuant to any contractual remedies available to Regeneron, an amount equal to
the sum of the Maximum Annual Discovery Program Costs for each of the years,
including the remaining unpaid Maximum Annual Discovery Program Cost for the
Contract Year in which such termination is effective, that would have been the
remainder of the term of the Discovery Program but for the termination of this
Agreement. 

     

              12.11 Termination by Sanofi At
Will. Sanofi shall be
entitled to terminate this Agreement at any time (except following a material
breach of this Agreement by Sanofi pursuant to Section 12.2) without cause upon three months’ written
notice to Regeneron. If Sanofi terminates the Agreement under this Section 12.11, then Sanofi shall pay to Regeneron within
five (5) days of its notice of termination, an amount equal to the sum of the
Maximum Annual Discovery Program Costs for each of the years, including the
Remaining Unpaid Maximum Annual Discovery Program Cost for the Contract Year in
which such termination is effective, that would have been the remainder of the
term of the Discovery Program but for the termination of this Agreement. In
addition, Sanofi shall complete GLP toxicology studies conducted by Sanofi at
the time of termination, if applicable, and such other critical activities
conducted by Sanofi at the time of termination that cannot be transferred to
Regeneron without a material adverse effect on the completion of such
activities. In the event of such termination, in addition to the provisions of
Section 12.8, the following shall apply: 

     

                   (a) the rights granted to
Sanofi under Sections 2.16 and 2.17 shall automatically terminate; and


     

    44 

     

    

    
    


                   (b) Regeneron shall be granted a non-exclusive, non-transferable, royalty
bearing (in accordance with Section 4.5) worldwide license with the right to
sublicense under Sanofi Target IP existing at the effective time of termination
solely for use to develop and commercialize (i) MTCs against Program Targets,
and (ii) any other Antibodies against Program Targets in existence and included
in the Discovery Program at the effective time of termination. 

     

    ARTICLE 13 

     

    ARBITRATION 

     

              13.1 Binding Arbitration. In the event the Parties cannot reach
agreement with respect to (i) the commercial reasonableness of the budget for
the Initial Development Plan for a Product Candidate, (ii) the royalty on Net
Sales of Immunoconjugates under Section 2.11(d)(i) of this Agreement, (iii) whether a breach
constitutes a “material breach” as described in Section 12.2 of this Agreement, and (iv) audits under
Section 7.2(d) above, and such disputes are not resolved by
the Executive Officers in accordance with Section 3.3(b) above, then the following shall apply:


     

                   (a) General. The respective disputed issue shall be
referred to binding arbitration by one (1) arbitrator who shall be an
independent expert in the pharmaceutical or biotechnology industry mutually
acceptable to the Parties. The Parties shall use their best efforts to mutually
agree upon one (1) arbitrator; provided, however, that if the Parties have not done so within
ten (10) days after initiation of arbitration hereunder, or such longer period
of time as the Parties have agreed to in writing, then such arbitrator shall be
an independent expert as described in the preceding sentence selected by the New
York office of the American Arbitration Association. Such arbitration shall be
limited to casting the deciding vote with respect to the disputed issues as more
fully described in Sections 13.1 (b)-(e) below. In connection therewith, each Party
shall submit to the arbitrator in writing its position on and desired resolution
of such matter. Such submission shall be made within ten (10) days of the
selection or appointment of the arbitrator, and the arbitrator shall rule on
such matter within ten (10) days of receipt of the written submissions by both
Parties. The arbitrator shall select one of the Party’s positions as his or her
decision, and shall not have authority to render any substantive decision other
than to so select the position of either Regeneron or Sanofi. Except as provided
in the preceding sentence, such arbitration shall be conducted in accordance
with the then-current Commercial Arbitration Rules of the American Arbitration
Association. The arbitrator’s ruling shall be final and binding upon the
Parties. The costs of any arbitration conducted pursuant to this Section 13.1 shall be borne equally by the Parties. The
Parties shall use diligent efforts to cause the completion of any such
arbitration within sixty (60) days following a request by any Party for such
arbitration.

     

                   (b) Initial Development Plan
Budget. The specific issue
that shall be submitted to the arbitrator shall be limited to determining the
overall commercial reasonableness of the budget that is the subject of the
dispute. If the arbitrator determines that such budget is commercially
reasonable, then the dispute shall be deemed finally resolved and such
resolution shall be binding on the Parties. However, if the arbitrator
determines that such budget is not commercially reasonable, then the arbitrator
shall, within fifteen (15) days after such determination, render a final
determination as to what modifications must be made to such budget in order for
it to be commercially reasonable (the “Budget Modification
Decision”). In connection with reaching a Budget Modification
Decision, the arbitrator may order the Parties to produce any documents or other
information which are relevant to such final decision, and the Parties shall
submit such documents or other information, together with their respective
proposed resolutions which shall consist of their proposed modifications to the
budget in order for it to be commercially reasonable, at least five (5) days
prior to the date a Budget Modification Decision is required to be rendered as
provided above. In rendering the final decision, the arbitrator shall be limited
to choosing a resolution proposed by a Party without modification.


     

    45 

     

    

    
    

     

                   (c) **********: The issue that shall be submitted to the
arbitrator shall be the royalty rate to apply under Section 2.11(d)(i). 

     

                   (d) Material Breach Under Section 12.2:
The issue that shall be
submitted to the arbitrator shall be whether the breach committed by a Party
meets the requirements for a material breach under Section 12.2 of this Agreement.

     

                   (e) Audit Disputes. The issue that shall be submitted to the
arbitrator shall be disputes as described under Section 7.2(d) of this Agreement. 

     

    ARTICLE 14
MISCELLANEOUS

     

              14.1 Governing Law; Submission to

              14.2 Waiver. Waiver by a Party of a breach hereunder by
the other Party shall not be construed as a waiver of any subsequent breach of
the same or any other provision. No delay or omission by a Party in exercising
or availing itself of any right, power or privilege hereunder shall preclude the
later exercise of any such right, power or privilege by such Party. No waiver
shall be effective unless made in writing with specific reference to the

receipt, if transmitted by facsimile (if such transmission is made during
regular business hours of the recipient on a Business Day; or otherwise, on the

    46

     

    

    
    


              14.4 Entire Agreement. This Agreement and the License and
Collaboration Agreement contain the complete understanding of the Parties with
respect to the subject matter hereof and thereof and supersede all prior
understandings and writings relating to the subject matter hereof and thereof.
It is understood and agreed that in the event of any conflict or inconsistency
between this Agreement and the License and Collaboration Agreement, this
Agreement shall control regarding the Parties’ rights and obligations with
respect to any Antibody (including any MTC), Lead Candidate or Product Candidate
in the Discovery Program (prior to Sanofi’s exercise of its Opt-In Rights with
respect to such Product Candidate), and the License and Collaboration Agreement
shall control regarding the Parties’ rights and obligations with respect to any
Licensed Product from and after the time a Product Candidate becomes a Licensed
Product. 

     

              14.5 Amendments. No provision in this Agreement shall be
supplemented, deleted or amended except in a writing executed by an authorized
representative of each of Sanofi and Regeneron. 

     

              14.6 Interpretation. The captions to the several Articles and
Sections of this Agreement are included only for convenience of reference and
shall not in any way affect the construction of, or be taken into consideration
in interpreting, this Agreement. In this Agreement: (a) the word “including”
shall be deemed to be followed by the phrase “without limitation” or like
expression; (b) references to the singular shall include the plural and vice
versa; (c) references to masculine, feminine and neuter pronouns and expressions
shall be interchangeable; and (d) the words “herein” or “hereunder” relate to
this Agreement. Each accounting term used herein that is not specifically
defined herein shall have the meaning given to it under GAAP, but only to the
extent consistent with its usage and the other definitions in this Agreement.


     

              14.7 Severability. If, under applicable Laws, any provision
hereof is invalid or unenforceable, or otherwise directly or indirectly affects
the validity of any other material provision(s) of this Agreement in any
jurisdiction (“Modified Clause”), then, it is mutually agreed that this
Agreement shall endure and that the Modified Clause shall be enforced in such
jurisdiction to the maximum extent permitted under applicable Laws in such
jurisdiction; provided that the Parties shall consult and use all
reasonable efforts to agree upon, and hereby consent to, any valid and
enforceable modification of this Agreement as may be necessary to avoid any
unjust enrichment of either Party and to match the intent of this Agreement as
closely as possible, including the economic benefits and rights contemplated
herein.

     

              14.8 Assignment. Except as otherwise expressly provided
herein, neither this Agreement nor any of the rights or obligations hereunder
may be assigned by either Sanofi or Regeneron without (a) the prior written
consent of Regeneron in the case of any assignment by Sanofi or (b) the prior
written consent of Sanofi in the case of an assignment by Regeneron, except in
each case (i) to an Affiliate of the assigning Party that has and will continue
to have the resources and financial wherewithal to fully meet its obligations
under this Agreement, provided that the assigning Party shall remain
primarily liable hereunder notwithstanding any such assignment, or (ii) to any
Third Party who acquires all or substantially all of the business of the
assigning Party by merger, sale of assets or otherwise, so long as such
Affiliate or Third Party agrees in writing to be bound by the terms of this
Agreement. The assigning Party shall remain primarily liable hereunder
notwithstanding any such assignment. Any attempted assignment in violation
hereof shall be void.

     

    47

     

    

    
    


              14.9 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the Parties hereto and their respective successors and
permitted assigns, and shall also inure to the benefit of the Regeneron
Indemnitees and Sanofi Indemnitees to the extent provided in the last sentence
of Section 14.12 below. 

     

              14.10 Affiliates. Each Party may carry out its obligations
under this Agreement through its Affiliates and absolutely, unconditionally and
irrevocably guarantees to the other Party prompt performance when due and at all
times thereafter of the responsibilities, liabilities, covenants, warranties,
agreements and undertakings of its Affiliates pursuant to this Agreement.
Without limiting the foregoing, neither Party shall cause or permit any of its
Affiliates to commit any act (including any act or omission) which such Party is
prohibited hereunder from committing directly. Sanofi shall not, directly or
indirectly, cause or direct Sanofi Pasteur or Merial Limited to take any action
for which Sanofi and its Affiliates are prohibited hereunder from committing.
Each Party represents and warrants to the other Party that it has licensed or
will license from its Affiliates the Patents and Know-How owned by its
Affiliates that are to be licensed (or sublicensed) to the other Party under
this Agreement. 

     

              14.11 Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original but which together shall
constitute one and the same instrument. 

     

              14.12 Third Party Beneficiaries. None of the provisions of this Agreement
shall be for the benefit of or enforceable by any Third Party, including any
creditor of any Party hereto. No Third Party shall obtain any right under any
provision of this Agreement or shall by reason of any such provision make any
claim in respect of any debt, liability or obligation (or otherwise) against any
Party hereto. Notwithstanding the foregoing, Article 10 is intended to benefit, in addition to the
Parties, the other Regeneron Indemnitees and Sanofi Indemnitees as if they were
parties hereto, but this Agreement is enforceable only by the Parties.


     

              14.13 Relationship of the Parties. Each Party shall bear its own costs incurred
in the performance of its obligations hereunder without charge or expense to the
other Party except as expressly provided in this Agreement. Neither Sanofi nor
Regeneron shall have any responsibility for the hiring, termination or
compensation of the other Party’s employees or for any employee compensation or
benefits of the other Party’s employees. No employee or representative of a
Party shall have any authority to bind or obligate the other Party to this
Agreement for any sum or in any manner whatsoever, or to create or impose any
contractual or other liability on the other Party without said Party’s approval.
For all purposes, and notwithstanding any other provision of this Agreement to
the contrary, Regeneron’s legal relationship under this Agreement to Sanofi, and
Sanofi’s legal relationship under this Agreement to Regeneron, shall be that of
an independent contractor. Nothing in this Agreement shall be construed to
establish a relationship of partners or joint ventures between the Parties or
any of their respective Affiliates.

     

    48

     

    

    
    


              14.14 Limitation of Damages. EXCEPT AS SET FORTH IN SECTION 12.10, IN NO EVENT SHALL REGENERON OR SANOFI BE
LIABLE FOR SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES
(INCLUDING, WITHOUT LIMITATION, LOSS OF PROFITS) SUFFERED BY THE OTHER PARTY,
REGARDLESS OF THE THEORY OF LIABILITY (INCLUDING CONTRACT, TORT, NEGLIGENCE,
STRICT LIABILITY OR OTHERWISE) AND REGARDLESS OF ANY PRIOR NOTICE OF SUCH
DAMAGES. HOWEVER, NOTHING IN THIS SECTION 14.14 IS INTENDED TO LIMIT OR RESTRICT THE
INDEMNIFICATION RIGHTS AND OBLIGATIONS OF EITHER PARTY HEREUNDER WITH RESPECT TO
THIRD PARTY CLAIMS. 

     

              14.15 Non-Solicitation. During the Term and for a period of two (2)
years thereafter, neither Party shall solicit or otherwise induce or attempt to
induce any employee of the other Party directly involved in the performance of
the Discovery Program to leave the employment of the other Party and accept
employment with the first Party. Notwithstanding the foregoing, this prohibition
on solicitation does not apply to actions taken by a Party solely as a result of
an employee’s affirmative response to a general recruitment effort carried
through a public solicitation or general solicitation. 

     

              14.16 No Strict Construction. This Agreement has been prepared jointly and
will not be construed against either Party.
