3.6    Manner of Payments. Following the First Commercial Sale, royalty payments due to LICR hereunder shall be made quarterly by  4-AB or its Affiliate no later than forty-five (45) days following completion of each calendar quarter with respect to Licensed Products sold during the prior calendar quarter.  Each payment shall be accompanied by a report setting forth for the relevant calendar quarter the information and basis on which such royalties have been calculated.  All reports delivered pursuant to this Agreement shall be deemed Confidential Information of 4-AB subject to Article VI.  All payments to be made pursuant to this Agreement shall be payable in Dollars by bank wire transfer in immediately available funds to such bank account as LICR shall designate. If any payment is not made on or before the due date specified herein, 4-AB will pay interest on the outstanding amount until paid in full if requested to do so by LICR. Interest will be charged at a rate equal to the “Intended Federal Funds Rate” or equivalent plus [**] as specified by the Federal Open Market Committee and published by the US Federal Reserve Board. 
3.7    Tax Withholding. Any tax, duty or other levy paid or required to be withheld by 4-AB on account of royalties payable to LICR under this Agreement shall be deducted from the amount of royalties otherwise due. 4-AB shall secure and send to LICR proof of payment of any such taxes, duties or other levies withheld and paid by 4-AB for the benefit of LICR, and cooperate at LICR’s reasonable request to ensure that amounts withheld are reduced, creditable (or otherwise recoverable) to the fullest extent permitted by the relevant jurisdiction.
3.8    Audit Right. Following the First Commercial Sale and during the Term of this Agreement and a period of five (5) years thereafter, 4-AB shall keep, and shall cause its Affiliates and Sublicensees to keep, full, true and accurate books and records containing all particulars relevant to its sales of Licensed Products in sufficient detail to enable LICR to verify the amounts payable to it under this Agreement for the preceding five (5) year period.  LICR shall have the right, not more than once during any calendar year, to have the books and records of 4-AB and its Affiliates audited by an independent certified public accounting firm of international standing.  4-AB shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the Sublicensee to make reports to 4-AB or its Affiliates, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records to LICR’s auditors to the same extent required of 4-AB and its Affiliates under this Section.  Audits under this Section shall be conducted during normal business hours, upon at least forty-five (45) days’ prior written notice, and for the sole purpose 

10

of verifying royalties payable to LICR under this Agreement.  All information and data reviewed in any audit conducted under this Section shall be used only for the purpose of verifying royalties payable to LICR under this Agreement and shall be treated as Confidential Information of 4-AB subject to the terms of this Agreement.  LICR shall cause its accounting firm to enter into an acceptable confidentiality agreement with 4-AB and its Affiliates and Sublicensees, as applicable.  The accounting firm shall disclose to LICR only whether the royalty reports are correct or incorrect and the specific details concerning any discrepancies.  No other information shall be provided to LICR. LICR shall bear the full cost of such audits, unless such inspection leads to the discovery of a discrepancy of greater than the greater of ten percent (10%) in reporting to LICR's detriment, or of $50,000, for any calendar year.  In such instance, 4AB agrees to pay the reasonable cost of such audit plus interest as stipulated in Section 3.6 from and after the date the audit report is delivered to 4AB.
ARTICLE IV    
INTELLECTUAL PROPERTY
4.1    Licensed Patent Rights.  The Parties acknowledge, agree and confirm that (i) Licensed Antibody results, research data, know-how, materials, compounds and inventions which are created by the LICR or 4AB during the course of and as a direct result of carrying out the program under the Prior Agreement generated under the Prior Agreement are jointly owned between LICR and 4-AB (subject to LICR’s obligations to MSKCC under the interinstitutional agreements dated September 17, 2007 and January 1, 2013 between LICR and MSKCC), and (ii) all other  inventions and know-how shall be owned in accordance with inventorship under U.S. patent laws.  4-AB (either directly or through its Affiliates or Sublicensees) shall be responsible, at its expense, for the preparation, filing, prosecution and maintenance of all Licensed Patent Rights (including, for clarity, controlling any interference, derivation, post-grant review, inter-partes review, re-examination, reissue, opposition or cancellation proceeding with respect thereto).  4-AB shall consult with and keep LICR informed of material issues relating to the preparation and filing, prosecution and maintenance of the Licensed Patent Rights (including, for clarity, controlling any interference, derivation, post-grant review, inter-partes review, re-examination, reissue, opposition or cancellation proceeding with respect thereto), and shall furnish to LICR copies of all material documents relevant to such preparation, filing, prosecution or maintenance.  In the event that 4-AB desires to abandon any patent or patent application within the Licensed Patent Rights, it shall provide LICR with reasonable prior written notice of such intended abandonment, and LICR shall have the right, at its expense, to prepare, file, prosecute, and maintain the relevant Patent Rights.  
4.2    Enforcement of Licensed Patent Rights; Defense of Infringement Actions.  Each Party shall promptly notify the other in writing of any known or suspected Third Party infringement of any Licensed Patent Rights or if any action for a declaration of non-infringement or invalidity of Licensed Patent Rights is made by a Third Party, or if any allegation of infringement of Third Party patents is made against either Party or any Affiliates or Sublicensees as a result of the manufacture, use or sale of a Licensed Product.
(a)    First Right to Respond.  4-AB (either directly or through its Affiliates or Sublicensees) shall have the first right to respond to any challenge or infringement of the Licensed Patent Rights at its own expense.  In the event 4-AB elects to so respond, LICR will, at 4-AB’s sole expense, cooperate with 4-AB’s legal counsel, join in such suits as may be brought by 4-AB to enforce the Licensed Patent Rights, and be available at 4-AB’s reasonable request to be an expert witness or otherwise to assist in such proceedings, at 4-AB’s sole expense.  During the pendency of any such suit, 4-AB may withhold from its royalty payments otherwise due to LICR in relation only to the disputed Licensed Patent Rights, fifty percent (50%) of the costs incurred by 4-AB in connection with such suit, provided that in no event may the royalty payments otherwise due to LICR in respect of disputed Licensed Patent Rights, be reduced 

11

by more than fifty percent (50%) by operation of this Section 4.2(a).  Any royalty payments due to LICR in relation to Licensed Patent Rights not in dispute, shall be paid in full. If 4-AB recovers monetary damages from a Third Party in connection with any action described in this Section 4.2(a), such damages shall be applied in the following manner: (i) first, 4-AB shall be reimbursed for all costs and expenses incurred by it in connection with such action; (ii) second, LICR shall be reimbursed for any royalties withheld during the pendency of such suit; and (iii) any remaining damages shall be divided between the Parties, with LICR receiving the portion equal to the amount of royalties it would have received if such remaining compensatory damages had been an equivalent amount of Net Sales.
(b)    Second Right to Respond.  If, within three (3) months of providing to or receiving from 4-AB notice of Third Party infringement pursuant to this Section 4.2, 4-AB does not exercise its first right to initiate legal action under this Section or initiate discussions to avert such suit (by license or otherwise), then LICR shall have the option to do so at its sole expense and may, at its option, join 4-AB as a party in such suit; provided that, in determining whether or not to take action, LICR shall give good faith consideration to the position of 4-AB in declining to bring such action.  In such event, all amounts recovered from such Third Party shall be retained by LICR, after reimbursement to 4-AB for any expenses it may have incurred in connection with such suit.
4.3    Cooperation.  Each Party hereby agrees: (a) to make its employees, agents and consultants reasonably available to the other Party (or to the other Party’s authorized attorneys, agents or representatives), to the extent reasonably necessary to enable such Party to undertake patent prosecution and maintenance as contemplated by this Agreement; (b) to cooperate, if necessary and appropriate, with the other Party in gaining patent term extensions wherever applicable to Patent Rights that are subject to this Agreement; and (c) to endeavor in good faith to coordinate its efforts with the other Party to minimize or avoid interference with the prosecution and maintenance of the other Party’s patent applications that are subject to this Agreement.  For the avoidance of doubt, each Party agrees that its employees, agents and consultants shall provide any and all information required for the other Party to comply with its relevant duties of disclosure as required by applicable law in the United States or any other jurisdiction.
4.4    Patent Term Restoration. 4-AB shall retain the sole and exclusive right to make any patent term restoration election or its equivalent, anywhere in the world, including under 35 U.S.C. §156 and its foreign counterparts with respect to any Licensed Patent Rights; provided, however, that 4-AB shall reasonably consider any input from the Licensors with respect to the extension of any Licensed Patent Right. LICR shall, and shall cause MSKCC to, abide by such elections and cooperate, as reasonably requested by 4-AB, in connection with the foregoing (including by providing appropriate information and executing appropriate documents).
4.5    Recording. If 4-AB deems it necessary or desirable to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate government authorities in one or more jurisdictions throughout the world, then 4-AB shall submit to LICR any proposed evidence of such recording.  LICR shall execute and deliver, and shall cause MSKCC to execute and deliver, to 4-AB any reasonable documents that are consistent with this Agreement and necessary or desirable, in 4-AB’s reasonable judgment, to complete such registration or recordation and 4-AB may make complete such registration or recordation.

REPRESENTATIONS, WARRANTIES AND COVENANTS
5.1    By LICR.  LICR hereby represents and warrants and covenants to 4-AB that:
(a)    this Agreement is a legal and valid obligation binding upon LICR and enforceable in accordance with its terms and, except as otherwise set forth herein, the execution, delivery and performance of this Agreement by LICR does not conflict with any agreement, instrument or understanding to which LICR is a party or by which it is bound;

(a)    The execution and delivery of this Agreement by 4-AB and the performance by 4-AB of the transactions contemplated hereby have been duly authorized by all appropriate 4-AB corporate action; and

13
[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request.  An unredacted version of this exhibit has been filed separately with the Commission.




(b)    This Agreement is a legal and valid obligation binding upon 4-AB and enforceable in accordance with its terms, and the execution, delivery and performance of this Agreement by 4-AB does not conflict with any agreement, instrument or understanding to which 4-AB is a party of or by which it is bound.
(c)    as of the Effective Date, to the best of 4-AB’s knowledge there are no claims, judgments or settlements against or owed by a 4-AB or any of its Affiliates or, to the best of 4-AB’s knowledge, pending or threatened claims, judgments or settlements against 4-AB or any of its Affiliates, relating to the Licensed Patent Rights, Licensed Know-How or 4-AB’s Patent Rights and Know-How that are reasonably expected to materially impact 4-AB’s ability to develop, manufacture or commercialize Licensed Products; and
(d)    to the best of 4AB’s knowledge, all obligations, if any, under 37 CFR §1.56  have been satisfied and shall continue to be satisfied, for all patents and patent applications within the Licensed Patent Rights.
5.3    Warranty Disclaimer. Except as expressly set forth in this Agreement, NEITHER PARTY MAKES ANY REPRESENTATION OR EXTENDS ANY WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, AND EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, ALL SUCH WARRANTIES ARE HEREBY DISCLAIMED, INCLUDING WARRANTIES ARISING BY COURSE OF DEALING, PERFORMANCE, CUSTOM OR USAGE IN THE TRADE, AND IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
5.4    Indemnification.
(a)    4-AB Indemnity. 4-AB shall indemnify, defend and hold harmless each Licensor and their respective directors, officers, employees and agents, and their respective successors, heirs and assigns (the “LICR Indemnitees”) from and against any liability, damage, loss or expense (including reasonable outside attorneys’ fees and expenses of litigation) (collectively, “Losses”) incurred by or imposed upon such LICR Indemnitees, or any of them, resulting from any claim, action or proceeding brought or initiated by a Third Party (each a “ Claim”) to the extent that such Claim arises out of: (i) the breach or alleged breach of any obligation, representation or warranty of 4-AB under this Agreement; or (ii) the negligence or willful misconduct of any 4-AB Indemnitee; provided that (x) the LICR Indemnitees comply with the procedure set forth in subsection (c) below; and (y) such indemnity shall not apply to the extent such Claim arises from (i) the breach or alleged breach of any obligation, representation or warranty of LICR under this Agreement; or (ii) the negligence or willful misconduct of any LICR Indemnitee. 


(b)    LICR Indemnity.  LICR shall indemnify, defend and hold harmless 4-AB, its Affiliates and Sublicensees and their respective directors, officers, employees, and agents, and their respective successors, heirs and assigns (the “4-AB Indemnitees”) from and against any Loss incurred by or imposed upon such 4-AB Indemnitees, or any of them, in connection with any Claim arising arises out of: (i) the breach or alleged breach of any obligation, representation or warranty of LICR under this Agreement; or (ii) the negligence or willful misconduct of any LICR Indemnitee; provided that (x) the 4-AB Indemnitees comply with the procedure set forth in subsection (c) below; and (y) such indemnity shall not apply to the extent such Claim arises from (i) the breach or alleged breach of any obligation, representation or warranty of 4-AB under this Agreement; or (ii) the negligence or willful misconduct of any 4-AB Indemnitee.

(c)    Indemnification Procedures.  In the event that a Party intends to claim indemnification under this Article V, such Party shall promptly notify the indemnifying Party thereof, and the indemnifying Party shall assume the defense thereof with counsel mutually satisfactory to the Parties; provided, however, that an indemnified Party shall have the right to retain its own counsel, with the fees and expenses to be paid by indemnifying Party, if representation of such indemnified Party by the counsel retained by the indemnifying Party would be inappropriate due to actual or potential differing interests between such indemnified Party and any other party represented by such counsel in such proceedings.  The indemnity obligation set forth in this Section 5.4 shall not apply to amounts paid in settlement of any claims, suits, actions, demands or judgments if such settlement is effected without the consent of the indemnifying Party, which consent shall not be unreasonably withheld.  The failure to deliver notice to the indemnifying Party within a reasonable time after the commencement of such action, if prejudicial to its ability to defend such action, shall relieve the indemnifying Party of any liability to the indemnified Party under this Article V, but the omission to so deliver notice to the indemnifying Party will not relieve it of any liability that it may have to any indemnified Party otherwise than under this Article V.  The indemnified Party under this Article V shall cooperate fully with the indemnifying Party and its legal representatives in the investigation of any claim for which indemnification is sought hereunder.
5.5    Limitation of Liability.  NEITHER PARTY SHALL BE LIABLE TO THE OTHER, OR TO ANY THIRD PARTY CLAIMING THROUGH OR UNDER THE OTHER PARTY, FOR ANY LOST PROFITS OR FOR ANY INDIRECT, EXEMPLARY, PUNITIVE, SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY KIND ARISING OUT OF THIS AGREEMENT, EVEN IF IT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
ARTICLE VI    
CONFIDENTIAL INFORMATION
6.1    “Confidential Information” shall mean any technical, scientific or business information furnished by or on behalf of one Party or its Affiliates (the “Disclosing Party”) to the other Party or its Affiliates (the “Receiving Party”) in connection with this Agreement or the activities contemplated hereunder, regardless of whether such information is specifically designated as confidential and regardless of whether such information is in oral, written, electronic or other form.  The terms of this Agreement shall be considered Confidential Information of both Parties, subject to the provisions of this Article VI.  Confidential Information shall not include information that:
(a)    is generally available in the public domain or thereafter becomes available to the public through no act of the Receiving Party; or
(b)    was independently known to the Receiving Party prior to receipt thereof or was discovered independently by an employee of the Receiving Party who had no access to the information supplied by or on behalf of the Disclosing Party; or
(c)    was made available to the Receiving Party as a matter of lawful right by a Third Party who had no obligations of confidentiality to the Disclosing Party.
6.2    Obligations.  The Receiving Party agrees that it shall not, without the prior written consent of the Disclosing Party, directly or indirectly:
(a)    make any use of any portion of the Confidential Information of the Disclosing Party for purposes other than those set forth in this Agreement; or

15
[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request.  An unredacted version of this exhibit has been filed separately with the Commission.




(b)    disclose or transfer any portion of the Confidential Information to any person, except that the Receiving Party may disclose or permit the disclosure of Confidential Information to its Affiliates and their respective directors, officers, employees, consultants, and advisors, and, with respect to 4-AB and its Affiliates, their Sublicensees and subcontractors and partners and investors and potential investors in connection with a general financing transaction, who have an ethical or fiduciary duty to the Receiving Party or are otherwise obligated to maintain the confidential nature of such Confidential Information and who need to know such Confidential Information for the purposes set forth in this Agreement or for other legitimate business purposes.
Notwithstanding the above, the Receiving Party may disclose Confidential Information of the Disclosing Party when required by applicable laws or government rules or regulations (including without limitation, applicable securities regulations), provided that to the extent reasonably possible, the Receiving Party provides reasonable prior written notice of such disclosure to the Disclosing Party and takes reasonable efforts to avoid and/or minimize the extent of disclosure.
6.3    Upon expiration or termination of this Agreement and upon request of the Disclosing Party, all copies of any Disclosing Party’s Confidential Information shall be returned to the Disclosing Party, except that each Receiving Party may retain one (1) copy of the Confidential Information received hereunder in the possession of its legal counsel, solely for monitoring its obligations under this Agreement.
6.4    No option, license, or conveyance of such rights, express or implied, is granted to the Receiving Party in connection with any Confidential Information disclosed by the Disclosing Party, except for the express licenses granted in Article 2.  If any such rights are to be granted to the Receiving Party, such grant shall be expressly set forth in a separate written instrument.
6.5    Public Announcements. Other than as required by a Party or its Affiliates to comply with applicable laws or regulations, each Party agrees that the terms of this Agreement are Confidential Information and neither Party shall make any public announcement disclosing the terms of this Agreement without the prior written consent of the other Party (not to be unreasonably withheld) and shall, if required by law to make such public announcement: (a) to the extent possible, notify the other Party if it anticipates that it may be required to make such public announcement; (b) provide such other Party with a copy of such public announcement, or the relevant portions thereof, a reasonable time prior to its release (and any revisions to such public announcement a reasonable time prior to the release thereof); (c) consult with and follow any reasonable directions from the other Party with respect to disclosures in such public announcement; and (d) if disclosure cannot be avoided, only disclose Confidential Information to the extent necessary to comply with law.  LICR and 4-AB anticipate that they may desire to issue joint or individual press releases upon execution of this Agreement, and on the occurrence of significant development milestones (which for LICR shall relate to Select Licensed Products).  In each case the Parties shall coordinate with respect thereto. 4-AB and its Affiliates shall be entitled to disclose the results of their research, development and commercialization activities related to this Agreement in their sole and absolute discretion.  4-AB and its Affiliates will not use the names of a Licensor or the names of any of a Licensors officers, scientific faculty or researchers without such Licensor’s prior written consent in any press release, advertising or promotional materials. Public announcements and statements by 4-AB and its Affiliates reporting significant advances in the development and commercialization of Select Licensed Products will acknowledge Licensors’ role in the discovery and validation of the Licensed Antibody(s), consistent with the provisions of Appendix B attached hereto. 
6.6    Publications.  In the event either of the Licensors wish to publish, present, or otherwise disclose any results of the research program conducted under the Prior Agreement, LICR shall provide 4-

16
[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request.  An unredacted version of this exhibit has been filed separately with the Commission.




AB with copies of any such publication or presentation at least thirty (30) days prior to submission for publication or presentation.  4-AB shall, within a period of thirty (30) days of receipt of such publication or presentation, advise the applicable Licensor whether patent or commercial interests may be prejudiced by the proposed publication or presentation, in which case the Licensor shall delay submission of the publication or presentation for an additional period, not to exceed forty-five (45) days, in order to prepare and file appropriate Patent Rights. If 4-AB has not responded to LICR within the initial thirty (30) day time period, the proposed publication or presentation shall be deemed not to prejudice any patent or commercial interests and the Licensor shall be free to proceed with the proposed disclosure.
ARTICLE VII    
TERM AND TERMINATION
7.1    Term. This Agreement shall be effective as of the Effective Date and, unless terminated early pursuant to this Article VII, shall continue until the date on which 4-AB has no further financial obligations to LICR hereunder (the “Term”).
7.2    Termination for Material Breach. In the event that a Party has materially breached or defaulted in the performance of any of its obligations hereunder, and if such default is not corrected within sixty (60) days after receiving written notice from the other Party with respect thereto, such other Party shall have the right to terminate this Agreement by giving written notice to the breaching Party; provided that the time period for providing such notice of termination shall be extended for so long as the breaching Party is engaged in good faith efforts to cure such breach or default.
7.3    Termination for Convenience.  4-AB may terminate this Agreement at any time, for any reason or no reason, upon ninety (90) days’ prior written notice to LICR.
7.4    Termination for Insolvency. In the event a Party files for protection under the bankruptcy laws, makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not discharged within ninety (90) days of the filing thereof, then the other Party may terminate this Agreement effective immediately upon written notice to the Party.
7.5    General Effect of Termination.
(a)    Termination of Rights.  Upon any early termination of this Agreement by LICR by operation of Sections 7.2 or 7.4, or by 4-AB by operation of Section 7.3 the rights and licenses granted to 4-AB and its Affiliates under Section 2.1 shall terminate. Notwithstanding the foregoing, any Sublicensee shall become a direct licensee of the Licensors if the Sublicensee is not then in breach of its sublicense agreement with 4-AB or its Affiliate and the Sublicensee agrees in writing to abide by the terms and conditions of this Agreement including all financial consideration and other obligations to LICR, applicable to 4-AB and its Affiliates, provided that (i) the scope of the direct license granted by Licensors to such Sublicensee shall be co-extensive with the scope of the sublicense granted by 4-AB or its Affiliate to such Sublicensee and (ii) any such direct license to a Sublicensee shall not impose any representations, warranties, obligations or liabilities on Licensors that are not included in this Agreement.
(b)    Accrued Obligations.  Termination of this Agreement for any reason shall not release any Party hereto from any liability which, at the time of such termination, has already accrued to the other Party or which is attributable to a period prior to such termination, nor preclude either Party from 

17
[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request.  An unredacted version of this exhibit has been filed separately with the Commission.




pursuing any rights and remedies it may have hereunder or at law or in equity which accrued or are based upon any event occurring prior to such termination.
(c)    So lo long as there are no Sublicensees for which a direct license would be available under Section 7.5 (a), in the event (1) LICR terminates this Agreement pursuant to Sections 7.2 or 7.4 or 4-AB terminates this Agreement pursuant to Section 7.3, and (2) 4-AB and its Affiliates and Sublicensees (if applicable) have decided to discontinue the development and commercialization of Select Licensed Products, 4-AB shall, upon the written request of LICR, promptly enter into good-faith discussions (which obligation for good faith discussions shall not exceed sixty (60) days to reach an agreement in principle term sheet and, assuming such term sheet is reached,  one hundred twenty (120) days for agreement finalization) with LICR regarding providing a license to LICR under (i) 4-AB’s and its Affiliates interest in the Licensed Patent Rights and Licensed Know-How and (ii) 4-AB and its Affiliates Patent Rights and Know-How relating to any Select Licensed Product that was developed and/or commercialized by 4-AB or its Affiliates, to the extent not restricted by any Third Party agreements or obligations (the “Applicable IP”), solely to the extent necessary and for the purpose of LICR’s research, development and/or commercialization of Select Licensed Products.  In the event the Parties reach agreement on such a license to LICR hereunder, such agreement will provide reasonable cooperation and transfer of information, documents and materials constituting the Know-How within the Applicable IP by 4-AB and its Affiliates.  .
(d)    Survival.  Articles IV, VI and VIII and Sections 3.8, 5.3, 5.4, 5.5, 7.5, 9.1, 9.2, 9.4, 9.9, 9.10 and 9.12 hereof (and related definitions) shall survive the expiration or termination of this Agreement for any reason.  In addition, any other provision required to interpret and enforce the Parties’ rights and obligations under this Agreement shall also survive, but only to the extent required for the observation and performance of the aforementioned surviving portions of this Agreement.
ARTICLE VIII    
DISPUTE RESOLUTION
8.1    Dispute Resolution. Except for the right of either Party to apply to a court of competent jurisdiction for a temporary restraining order, a preliminary injunction or other equitable relief to preserve the status quo or prevent irreparable harm, any dispute, other than disputes regarding the construction, validity or enforcement of Patent Rights, arising between the Parties relating to, arising out of or in any way connected with this Agreement or any term or condition hereof, or the performance by either Party of its obligations hereunder, whether before or after termination of this Agreement, shall be resolved in accordance with this Section 8.1.
(a)    The chief executive officers of both Parties (or their respective designees) shall meet to attempt to resolve such dispute.
(b)    If the chief executive officers of the Parties (or their respective designees) cannot resolve such dispute within thirty (30) days after either Party requests such a meeting in writing, then upon written notice by either Party to the other Party, such dispute, controversy or claim shall be finally resolved by binding arbitration conducted in the English language in New York, New York, USA under the Commercial Arbitration Rules of the American Arbitration Association by three (3) arbitrators.   Each Party shall be entitled to appoint one (1) arbitrator. The Parties shall appoint their respective arbitrators within thirty (30) days after submission for arbitration.  The two (2) arbitrators so appointed shall agree on the appointment of the third (3rd) arbitrator from the list of arbitrators maintained by the American Arbitration Association. If the Parties’ appointed arbitrators shall fail to agree, within thirty (30) days from the date both Parties’ 

18
[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request.  An unredacted version of this exhibit has been filed separately with the Commission.




arbitrators have been appointed, on the identity of  the third (3rd) arbitrator, then such arbitrator shall be appointed by the appropriate administrative body of the American Arbitration Association.
(c)     Within ten (10) days of appointment of the full arbitration panel, the Parties shall exchange their final proposed positions with respect to the matters to be arbitrated, which shall approximate as closely as possible the closest positions of the Parties previously taken in previous negotiations.  Within thirty (30) days of appointment of the arbitration panel, each Party shall submit to the arbitrators a copy of the proposed position which it previously delivered to the other Party, together with a brief or other written memorandum supporting the merits of its proposed position. The arbitration panel shall promptly convene a hearing, at which time each Party shall have one (1) hour to argue in support of its proposed position. The Parties will not call any witnesses in support of their arguments.
(d)    The arbitration panel shall select either Party’s proposed position on the issue as the binding final decision to be embodied as an agreement between the Parties. In making their selection, the arbitrators shall not modify the terms or conditions of either Party’s proposed position, nor will the arbitrators combine provisions from both proposed positions. In the event the arbitrators seek the guidance of the law of any jurisdiction, the law of the State of New York, USA shall govern.
(e)    The arbitrators shall make their decision known to the Parties as promptly as possible by delivering written notice of their decision to both Parties. Such written notice need not justify their decision. The Parties will execute any and all papers necessary to obligate the Parties to the position selected by the arbitration panel within five (5) days of receipt of notice of such selection. The decision of the arbitrators shall be final and binding on the Parties, and specific performance may be ordered by any court of competent jurisdiction. Any arbitration award shall be subject to Section 5.5.
(f)    Parties will bear their own costs in preparing for the arbitration. The costs of the arbitrators will be equally divided between the Parties.
(g)    Any and all activities conducted under this Section 8.1 including any and all proceedings and decisions of the arbitration panel, shall be deemed Confidential Information of each of the Parties, and shall be subject to Article VI.
ARTICLE IX
