IE Introduced Program Technology or IE Research Technology (other than Biocatalysts that are derived from Biocatalysts that originated as IE Introduced Program Technology). 
 4.7 Right of First Negotiation – Biocatalyst Manufacturing. 
 (a) Codexis Right of First Negotiation. In the event that any Out-Sourcing Party seeks to out-source the manufacture of any
particular Biocatalyst introduced into the Program by Codexis or developed during the Research Term using Codexis Shuffling Technology (other than a Biocatalyst that is derived from a Biocatalyst that originated as IE Introduced Program Technology),
for use in a facility where Shell or an Affiliate of Shell, individually or collectively, is not [*] in such facility or [*], the Out-Sourcing Party, for a [*] year period following the expiration or termination of the Research
Term, shall provide written notice to Codexis and Codexis shall have a right of first negotiation for the manufacture of such particular Biocatalyst, under the terms and conditions of a separate Biocatalyst supply agreement which will be negotiated.
For purposes of this Section 4.7(a), “Out-Sourcing Party” shall mean IE or any Affiliate of IE (other than Shell or any Affiliate of Shell), or any Third Party that has been granted license rights, directly or indirectly, from IE or
any Affiliate of IE (other than Shell or an Affiliate of Shell). The date of Codexis’ receipt of such written notice from the Out-Sourcing Party will be the start of a ninety (90) day period during which, upon Codexis’ election, the
terms and conditions of such supply agreement will be negotiated regarding the Biocatalyst identified in such written notice. If mutually acceptable terms and conditions have not been agreed prior to the end of such ninety (90) day period, the
Out-Sourcing Party will be free to negotiate with Third Parties for the manufacture of such particular Biocatalyst, but may not enter into any agreement for such manufacture under terms and conditions that are less favorable to the Out-Sourcing
Party than the terms and conditions last offered to Codexis; provided, however, that, for the avoidance of doubt, such terms and conditions will include all business considerations as taken from the Out-Sourcing Party’s
perspective. 
 (b) No Change to Existing Rights. For purposes of clarification, except as expressly set forth in
this Section 4.7, nothing in this Agreement is intended to modify Codexis’ rights under Section 2.4 of the Codexis-Shell US License Agreement. In particular, without limiting the generality of the foregoing, in the event that IE or its

Affiliates or its licensees, as applicable, desires to outsource the manufacture of a Biocatalyst developed through the use of Codexis Shuffling Technology (other than Biocatalysts that are
derived from Biocatalysts that originated as IE Introduced Program Technology) in any facility other than a facility described in Section 4.7(a), Codexis’ rights under Section 2.4 of the Codexis-Shell US License Agreement shall apply with
respect to such outsourcing. 
 (c) Exception. In the event that Shell, or an Affiliate of Shell, [*] either
(i) the power to [*], or (ii) the [*], Codexis’ right of first negotiation under Section 4.7(a) will be governed solely by the provisions of Section 2.4 of the Codexis-Shell US License Agreement. Notwithstanding
anything to the contrary in the preceding sentence, for so long as Iogen Corporation is a licensee of IE and not [*], the rights of Iogen Corporation and its licensees, other than Shell and Affiliates of Shell, will continue to be governed by
the provisions of Section 4.7(a). 
 4.8 Derivatives of Codexis Program Technology. 
 (a) IE covenants and agrees that it and its Affiliates, and its and its Affiliates’ licensees (other than Shell and its
Affiliates), shall not modify or otherwise create, by use of any recombinant or other directed mutagenesis technology, any derivative of any Biocatalyst that originates from (i) Codexis Introduced Program Technology, (ii) Research
Technology developed by use of Codexis Shuffling Technology (other than Biocatalysts that originated from IE), or (iii) IE Introduced Program Technology and/or IE Background Technology incorporated into any [*] or combined with any
[*] (a Biocatalyst originating from any of (i), (ii) and (iii) is referred to as a “Codexis Biocatalyst”). For purposes of clarification, the rights of Shell and its Affiliates with respect to modification or creation
of any derivative of a Codexis Biocatalyst are governed by Section 9.4 of the Codexis-Shell US Research Agreement and Section 7.3 of the Codexis-Shell US License Agreement. Notwithstanding the first sentence of this Section 4.8(a), in the
event that (A) IE or any Affiliate of IE requests (whether such request comes directly from IE or an Affiliate of IE, or from Shell on behalf of IE or an Affiliate of IE) that Codexis modify or otherwise create a derivative of any Codexis
Biocatalyst in accordance with the provisions of Section 9.4 of the Codexis-Shell US Research Agreement and Section 7.3 of the Codexis-Shell US License Agreement, and (B) Codexis is unwilling or unable to perform such modification or
otherwise create such a derivative under terms that are (1) consistent with or below the full time equivalent (FTE) rates Codexis has most recently agreed to charge Shell for comparable work, including without limitation any calendar- and/or
inflation-based escalators, and (2) commercially reasonable with respect to the market-based, good faith expectations of IE or any Affiliate of IE regarding resource commitment requirements, including for example FTE person hours and equipment
time required, then Codexis shall so notify Shell US, IE or the Affiliate of IE, as applicable, in writing and IE or the Affiliate of IE, as the case may be, may modify or otherwise create the derivative of such Codexis Biocatalyst requested by
Shell US, IE or the Affiliate of IE, as applicable; provided, however, that IE or the Affiliate of IE, as the case may be, must modify or otherwise create such derivative

using its own, internal resources, and may not engage or otherwise use a Third Party or an independent contractor to modify or otherwise create such derivative; provided further
that such modification or creation of derivatives of Codexis Biocatalysts is not inconsistent with the rights, obligations and restrictions set forth in the Codexis Third Party Agreements; provided further that, in the event that Shell
or an Affiliate of Shell [*], then the rights of IE and any Affiliate of IE, as the case may be, to modify or create any derivative of any Codexis Biocatalyst will be governed solely by the provisions of Section 9.4 of the Codexis-Shell
US Research Agreement and Section 7.3 of the Codexis-Shell US License Agreement as applied to IE and any Affiliate of IE, mutatis mutandis. For purposes of clarification, notwithstanding the above, IE, any Affiliate of IE, and any
sublicensee of IE or an Affiliate of IE (other than Shell and its Affiliates) may make derivatives from any Biocatalyst that originated solely from an IE Biocatalyst, including without limitation Biocatalysts jointly developed by IE and Codexis;
provided that such Biocatalyst is not incorporated into any [*] or combined with any [*]. 
 (b) In
the event that IE modifies or otherwise creates any derivative of any Codexis Biocatalyst in accordance with the terms of Section 4.8(a), IE agrees to grant, and hereby grants to Codexis, subject to the terms and conditions of the IE Third Party
Agreements, a license limited to the right to grant sublicense rights solely to Shell US and its Affiliates under intellectual property Controlled by IE directed to such modified or otherwise created Codexis Biocatalyst to manufacture, have
manufactured, use, sell, offer for sale and import products within the Fuels Field, on a worldwide basis; such limited license neither granting to Codexis, nor permitting Codexis to reserve for Codexis, any right or license to manufacture, have
manufactured, use, sell, offer for sale or import any product under such intellectual property, within the Fuels Field, or to otherwise utilize or practice any such intellectual property within the Fuels Field. Codexis and Shell US each acknowledge
and agree that the sublicense rights received by Shell under this Section 4.8(b) that are the subject of the limited license granted by IE to Codexis pursuant to this Section 4.8(b) shall be deemed to be Program Patent Rights and Program Licensed
Technology (as defined in the Codexis-Shell US License Agreement), as applicable. In addition, IE agrees that the following terms shall apply to the intellectual property that is the subject of the license granted in this Section 4.8(b): (i) IE
covenants and agrees not to grant any right or license to Shell, or to an Affiliate of Shell, under such intellectual property in the Fuels Field, (ii) IE covenants and agrees that, in the event Shell or an Affiliate of Shell [*] either
(A) the power to [*], or (B) the [*], IE shall not, itself, utilize such intellectual property to make, use or sell Biocatalysts for any commercial purpose; provided that [*] shall have no impact on the rights of IE
with respect to the granting of rights to Third Parties to manufacture, have manufactured, use, sell, offer for sale and import any such Biocatalyst in the Fuels Field in effect immediately prior to [*], and (iii) in the event that IE,
or an Affiliate of IE, asserts that no payment is due to Codexis, or that the payment due to Codexis is less than the amount calculated under the terms of the Codexis-Shell US License Agreement based on an express argument that Codexis does not own
such intellectual property (exclusive of any other argument, assertion or contention, including but not limited to any argument, assertion or contention made in

regard to any dispute concerning whether such intellectual property is properly subject to this section), IE shall assign such intellectual property to Codexis. 
 (c) Notwithstanding the terms of Section 4.8(a), provided that Shell or an Affiliate of Shell has not [*] either (i) the
power to [*], or (ii) the [*], then IE shall have a right, after the later of (A) the [*] year anniversary of the expiration or termination of the Codexis-Shell US Research Agreement and (B) the [*] year
anniversary of the Effective Date, to modify or otherwise create derivatives of Codexis Biocatalysts; provided, however, that such modification or creation of derivatives of Codexis Biocatalysts is not inconsistent with the rights,
obligations and restrictions set forth in the Codexis Third Party Agreements. 
 (d) Notwithstanding anything in this
Agreement to the contrary, the limitations on IE regarding the modification or creation of any derivative of any Biocatalyst, as set forth in this Section 4.8, shall not reduce IE’s right to modify or create any such derivative to less than the
rights enjoyed by an unlicensed Third Party to modify or create any such derivative under Canadian law; provided, however that IE will not use any Codexis Introduced Program Technology, Codexis Background Technology or Research Technology developed
by use of Codexis Shuffling Technology that is Codexis Confidential Information; provided further that IE will not use any materials provided by Codexis, directly or indirectly, to IE or any Affiliate of IE; provided further that to the extent that
the practice of such derivative or modification requires the use of any Codexis Introduced Program Technology, Codexis Background Technology or Research Technology developed by use of Codexis Shuffling Technology that is the subject of a license
grant to IE, IE will not use any such modification or derivative for any commercial purpose without the prior written consent of Codexis. 
 4.9 No Other Rights. Except as expressly provided in this Agreement, no right, title or interest is granted by any Party to any other Party, by implication or otherwise. Further, all licenses and
other rights provided herein are subject and subordinate to any and all prior Third Party Agreements containing terms either overlapping or in conflict therewith.

Obligations. The Parties agree that, during the Term and for ten (10) years thereafter, all Confidential Information disclosed by one Party to the other Party(ies) hereunder shall be received and maintained by the receiving Party and its
Affiliates in strict confidence, shall not be used for any purpose other than the purposes expressly permitted by this Agreement, and shall not be disclosed to any Third Party. The obligations of confidentiality and non-use set forth in the first
sentence of this Section 7.1 will not apply to any information to the extent that it can be established by the receiving Party that such information: 
 (a) was already known to the receiving Party or its Affiliates at the time of disclosure without restriction as to confidentiality or use, as evidenced by records of the receiving Party and its
Affiliates; 
 (b) was generally available to the public or was otherwise part of the public domain at the time of its
disclosure to the receiving Party or its Affiliates; 
 (c) became generally available to the public or otherwise becomes
part of the public domain after its disclosure and other than through any fault of the receiving Party or its Affiliates in breach of this Agreement;

obligate such persons to obligations of confidentiality and non-use no less restrictive than those assumed by the Parties herein, and to assign to such Party all inventions made by such persons during the course of performing any tasks associated
with the Program. Further, each Party represents and warrants that those of its employees which perform work on the Program or otherwise have a need to know the other Party’s Confidential Information are bound by obligations of confidentiality
and non-use to the employer Party. Each Party may disclose Confidential Information of the other Party(ies) to such Party’s Affiliates, provided that any such Affiliate agrees prior to such disclosure

in confidence to potential or actual investment bankers, advisors (including without limitation financial advisors and accountants), investors, lenders, acquirers, merger partners, or other potential financial or strategic partners, and their
attorneys and agents, on a need to know basis; provided, however, that the receiving Party shall remain responsible for any failure by any Third Party who receives Confidential Information pursuant to this Section 7.1 to treat such
Confidential Information as required under this Article 7.

Information of the disclosing Party that the receiving Party is required to disclose under applicable laws or regulations or an order by a court or other regulatory body having competent jurisdiction; provided, however, that except
where impracticable, the receiving Party shall give the disclosing Party reasonable advance notice of such disclosure requirement (which shall include a copy of any applicable subpoena or order) and shall afford the disclosing Party a reasonable
opportunity to oppose, limit or secure confidential treatment for such required disclosure. In the event of any such required disclosure, the receiving Party shall disclose only that portion of the Confidential Information of the disclosing Party
that the receiving Party is legally required to disclose and, in the event a protective order is obtained by the disclosing Party, nothing in this Article 7 shall be construed to authorize the receiving Party to use or disclose any disclosing
Party Confidential Information to parties other than such court or regulatory body or beyond the scope of the protective order. 
 7.2 Harmonization with Licenses. The obligations of confidentiality and non-use set forth in this Article 7 shall not be construed as limiting the right of any Party to exercise any license granted it under this Agreement or the
Shell Agreements. 
 7.3 Publicity. Except to the extent required by law or regulation, no Party shall make any public
announcements concerning this Agreement or the terms hereof without the prior written consent of the other Parties, and the Parties shall agree on the content and timing of any such public announcement. This Agreement does not give any Party the

indemnifying Party or other site or facility operated by the indemnifying Party, its Affiliates or its subcontractors, as the term Disposed is defined in applicable Environmental Laws; 
 (c) any failure to obtain or maintain all permits and provide all notices required by Environmental Laws for the lawful operation of
any site of the indemnifying Party or any site of any supplier of the indemnifying Party or other facilities or sites operated by the indemnifying Party, its Affiliates, sublicensees or subcontractors; and 
 (d) any other actual or alleged act or omission relating to the handling or disposal of Hazardous Materials at any site of the
indemnifying Party or any site of any supplier (other than a Party as supplier) of the indemnifying Party or the handling or disposal of Hazardous Materials by the indemnifying Party, its Affiliates, sublicensees or subcontractors at any other
facility or site. 
 For purposes of this Section 9.4, “Environmental Law” shall mean any treaty, law, ordinance, regulation or

PCB’s, as such substances are defined under any applicable federal, state or local statute, regulation, rule or ordinance. 
 Notwithstanding anything in this Section 9.4 to the contrary, the indemnification obligation of IE to Shell and its Affiliates shall not apply to any site or facility operated by IE, or its Affiliates,
licensees or subcontractors, on behalf of Shell and its Affiliates, including without limitation the [*] facility proposed for [*] and the facility [*] facility; indemnities as to such facilities will be addressed in other
agreements. 
 9.5 Notification of Claim; Conditions to Indemnification Obligations. The provisions below shall govern a
Party’s right to receive indemnification under this Article 9. 
 (a) The Party seeking indemnification shall
promptly provide written notice (each such written notice, a “Claim Notice”) to the Indemnitor as soon as such Party becomes aware of a claim or suit for which indemnification may be sought pursuant hereto (provided that the failure
to give a Claim Notice promptly shall not prejudice the rights of the Indemnitees except to the extent that the failure to give such prompt notice materially adversely affects the ability of the Indemnitor to defend the claim or suit). 

(b) If the Indemnitor confirms in writing to the indemnified Party its intention to defend such claim or suit within fifteen
(15) business days after receipt of the Claim Notice, such Party, and such Party’s Indemnitees, shall permit the Indemnitor to control the defense of such claim or suit, including without limitation the right to select defense counsel;
provided that any assumption of the defense of a Third Party claim or suit by the Indemnitor shall not be construed as an acknowledgment that the Indemnitor is liable to indemnify the Party seeking indemnification or any of its Indemnitees in
respect of the Third Party claim or suit, nor shall it constitute a waiver by the Indemnitor of any defenses it may assert against the Party seeking indemnification, or any Indemnitee’s claim for indemnification. Upon receipt by the indemnified
Party of its intention to defend, the Indemnitor shall not be liable to the indemnified Party or to any of its Indemnitees for any legal expenses subsequently incurred by such indemnified Party or any of its Indemnitees in connection with the
analysis, defense or settlement of the Third Party claim or suit, except subsequent to termination of its right to defend as provided in Section 9.5(c)(ii), or with the prior written consent of the Indemnitor. In no event, however, may the
Indemnitor compromise or settle any claim or suit in a manner which admits fault or negligence on the part of any Indemnitee, or that otherwise materially affects such Indemnitee’s rights under this Agreement, or requires any payment by an
Indemnitee, without the prior written consent of such Indemnitee. 
 (c) If the Indemnitor fails to (i) provide to
the indemnified Party its confirmation in writing of its intention to defend such claim or suit within the fifteen (15) business day period set forth in Section 9.5(b); or (ii) diligently and reasonably defend such suit or claim at any
time, its right to defend the claim or suit shall terminate immediately in the case of (i) and otherwise upon twenty (20) days’ written notice to the Indemnitor and the indemnified Party may (A) assume the defense of such claim
or suit

 - 44 - 








 
at the sole expense of the Indemnitor and (B) settle or compromise such claim or suit without the consent of the Indemnitor. 
 (d) The indemnified Party, and such Party’s Indemnitees, shall reasonably cooperate with the Indemnitor, at the
Indemnitor’s cost and expense, in the defense of such claim or suit, and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be
reasonably requested in connection therewith. Such cooperation shall include access during normal business hours by the indemnifying Party to, and reasonable retention by the indemnified Party of, records and information that are reasonably relevant
to such Third Party claim or suit and, as reasonably requested by the indemnifying Party, making the indemnified Party and its employees and agents available on a mutually convenient basis to provide additional information and explanation of any
records or information provided. 
 (e) An indemnified Party, acting on behalf of itself and all other Indemnitees, shall
have the right, but not the duty, at its sole cost and expense, to participate in, but not control, the defense of any claim or suit hereunder with attorneys of its own selection without relieving the Indemnitor of any of its obligations hereunder.

 (f) In the event that it is determined by an arbitrator pursuant to an arbitration conducted in accordance with
Schedule 11.9, that the Indemnitor is not obligated to indemnify, defend or hold harmless the indemnified Party or any of its Indemnitees from and against the Third Party claim or suit, the indemnified Party shall reimburse the Indemnitor for any
and all costs and expenses (including lawyers’ fees and costs) incurred by the Indemnitor in its defense of the Third Party claim or suit with respect to such indemnified Party. Notwithstanding the foregoing, each of the Parties agrees not to
bring any such arbitration proceeding until there has been either (i) a final, non-appealable decision reached by a court with valid jurisdiction or (ii) a binding settlement, in each case, with respect to Losses arising out of any such
Third Party claims or suits. 
 9.6 Other Indemnification Obligations. Notwithstanding anything to the contrary, the
provisions of this Article 9 are not intended, and shall not be deemed, to modify the terms and conditions regarding the indemnification obligations, if any, of any Party set forth in the Shell Agreements; provided, however, that
notwithstanding anything to the contrary in this Agreement, the Codexis-Shell US Research Agreement or the Codexis-Shell US License Agreement, for purposes of Section 10.2(b)(iv) of the Codexis-Shell US Research Agreement and Section 8.1(c) and
Section 8.2(e) of the Codexis-Shell US License Agreement, IE will always be deemed to be an Affiliate (as such term is defined in the Codexis-Shell US Research Agreement and the Codexis-Shell US License Agreement, as applicable) of Shell (as
such term is defined in the Codexis-Shell US Research Agreement and the Codexis-Shell US License Agreement, as applicable); provided further that, notwithstanding anything to the contrary in this Agreement, the Codexis-Shell US
Research Agreement or the Codexis-Shell US License

 ARTICLE 10 
 TERM AND TERMINATION 
 10.1 Term. 
 (a) The research term of this Agreement (the “Research Term”) will commence on the Effective Date and, unless
earlier terminated in accordance with Section 10.2, shall continue in effect until the earlier of the expiration or termination of (a) this Agreement, (b) the Codexis-Shell US Research Agreement or (c) the IE-Shell Canada [*]
Agreement, or successor or replacement thereof. 
 (b) The term of this Agreement (the “Term”) will
commence on the Effective Date and, unless earlier terminated in accordance with Section 10.4, shall continue in effect until the earlier of the expiration or termination of (a) the Codexis-Shell US License Agreement or (b) the IE-Shell
Canada [*] Agreement, or successor or replacement thereof. 
 10.2 Termination of Research Term At Will. Shell, in
its sole discretion, may terminate the Research Term at any time upon thirty (30) days prior written notice to Codexis and IE. 
 10.3 Termination due to Challenge of Patent. In the event that IE challenges in any country the validity of any issued patent that is within the Patent Rights licensed to Codexis under the Codexis-[*] Agreement, the licenses
granted by Shell to IE under the IE-Shell Canada [*] Agreement or the IE-Shell Canada [*] Agreement with respect to use of any technology originating from or derived from any [*] and/or any [*], may at Codexis’
option, be terminated as to the country of such issued patent, such termination to be effective upon written notice by Codexis to IE and Shell. 
 10.4 Termination Upon Material Breach. Material failure by a Party to comply with any of its obligations contained herein shall entitle a Party not in default and injured by such material failure
to give to a Party in default written notice (a “Default Notice”) specifying the nature of the default in reasonable detail, requiring such defaulting Party to make good or otherwise cure such default, and stating such
non-defaulting Party’s intention to terminate this Agreement if such default is not cured. If such default is not cured within sixty (60) days after the date the Default Notice was sent,

  
 [*] Certain
information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

then such non-defaulting Party shall be entitled, without prejudice to any other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in
equity, to terminate this Agreement by written notice of termination to the defaulting Party; provided, however, that if the Party receiving such Default Notice (the “Disputing Party”) has a reasonable basis for
disputing that it is in default and such Disputing Party provides written notice thereof to the Party that provided the Default Notice before the expiration of such sixty (60) day cure period, then the Disputing Party shall have the right,
prior to the expiration of such sixty (60) day period, to submit such dispute for resolution in accordance with the provisions of Section 11.9; provided further that in the event that as a result of such resolution, the Disputing
Party is found to be in default and such default is not cured within forty-five (45) days after the date of such resolution, then the Party that provided the Default Notice shall be entitled, without prejudice to any other rights conferred on
it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement by written notice of termination to the Disputing Party. A copy of any and all written notices given by any Party to any
other Party pursuant to this Section 10.4 shall also be given to the third Party to this Agreement. 
 10.5 Consequences of
Expiration or Termination of this Agreement. 
 (a) Upon termination of this Agreement by a Party pursuant to Section
10.4 (the terminating Party, the “Non-Breaching Party”): (i) all licenses and other rights granted by the Party in breach (the “Breaching Party”) to the Non-Breaching Party shall remain in full force and effect
in accordance with their respective terms, subject to the terms and conditions of this Agreement; (ii) all licenses and other rights granted by the Non-Breaching Party to the Breaching Party shall terminate and be of no further force or effect,
except as otherwise expressly set forth in this Section 10.5; and (iii) all other licenses and other rights granted by and among the Parties shall remain in full force and effect in accordance with their respective terms, subject to the terms
and conditions of this Agreement. 
 (b) Upon termination of this Agreement pursuant to Section 10.4, sublicenses granted
by the Breaching Party to an Affiliate or to a Third Party, as applicable, pursuant to a license granted by the Non-Breaching Party to the Breaching Party under this Agreement will survive, subject to the restrictions contained in this Agreement,
but shall be assigned to the Non-Breaching Party; provided that (i) such Affiliate or Third Party sublicensee is not the cause of the breach under Section 10.4, and (ii) such Affiliate or Third Party sublicensee is not in breach of,
and continues to fully perform all obligations under, the applicable sublicense agreement(s). 
 (c) Upon expiration or
termination of this Agreement, unless otherwise agreed to in writing by the applicable Parties, each Party will promptly return all records and materials in its possession or control containing or comprising the other Party’s Confidential

such expiration or termination of this Agreement. Notwithstanding anything to the contrary, each Party shall have the right to maintain one (1) copy of such records in its legal department
files for archive purposes; provided that such copy is kept pursuant to the surviving confidentiality obligations of this Agreement. 
 (d) The following articles and sections of this Agreement shall survive its termination or expiration: Articles 1, 3, 4, 5, 6, 7, 9, and 11, and Sections 2.3(d)(ii), 2.7, 8.4 and 10.5. In addition,
Section 10.6 shall survive in the event of the (i) expiration of this Agreement, or (ii) termination of this Agreement, other than a termination (A) due to the termination of the IE-Shell Canada [*] Agreement where IE, its
Affiliates and sublicensees retain no license rights with respect to any Codexis Introduced Program Technology or Codexis Research Technology, or (B) pursuant to Section 10.4 where IE is the Breaching Party. Termination of this Agreement will
have no effect on the rights and licenses granted under the Codexis-Shell US License Agreement and the IE-Shell Canada [*] Agreement.

Section 10.5(a), as applicable), or (iii) any other remedies which a Party may otherwise have. 
 10.6 Consequences of
Termination of the Codexis-Shell US License Agreement. 
 (a) Rights of IE. 
 (i) In the event that the Codexis-Shell US License Agreement terminates for any reason other than as a consequence of any action by
IE or its Affiliates, Codexis, effective as of the effective date of such termination, will grant, and hereby grants, to IE a non-exclusive, worldwide, royalty-bearing license under the Codexis Research Technology and Codexis Introduced Program
Technology in the Fuels Field, under all terms and conditions set forth in the Codexis-Shell US License Agreement, excluding Sections 2.4 and 7.3, and Articles 3 (except Section 3.5), 4 and 6 of the Codexis-Shell US License Agreement,
mutatis mutandis, and consistent with IE’s rights and obligations under this Agreement, for use in the manufacture, use, sale, offer for sale, and import of [*], derivatives of [*], and any [*] that are subject to a
specific [*] adopted in the [*], as of the date of such termination, in each case that are derived from Biomass (“Permitted Products”). The right to be granted by Codexis to IE under this Section 10.6(a) will include a
right to grant sublicense rights; provided that IE shall have no right to grant any sublicense under the rights granted by Codexis to IE under this Section 10.6(a) to Shell or any Affiliate of Shell; provided further that IE
shall have no right to utilize, for itself or any of its successors, for any commercial purpose, the rights granted to IE by Codexis under this Section 10.6(a) in the event that Shell [*] but, for

greater clarity, [*] shall have no impact on the rights of IE with respect to the granting of rights to Third Parties under the Codexis Introduced Program Technology and the Codexis
Research Technology in the Fuels Field in effect immediately prior to [*]; provided, further, that any such sublicense grant of Codexis Research Technology and Codexis Introduced Program Technology (i) is only a portion of
a grant of a technology package that includes IE Biofuel Process Technology necessary for the manufacture, use, sale, offer for sale, and import of one or more Permitted Products, and (ii) would terminate, automatically and without a
requirement of further action by IE, if the sublicensee independently exercises the rights granted under such sublicense with respect to Codexis Research Technology or Codexis Introduced Program Technology and not together or in concert with IE
Biofuel Process Technology. For purposes of clarification, any sublicense granted by IE under the rights granted by Codexis to IE under this Section 10.6(a) shall include a prohibition against the use of Codexis Research Technology and Codexis
Introduced Program Technology unless such Codexis Research Technology and Codexis Introduced Program Technology is used solely for use in direct connection with specific facilities that use IE Biofuel Process Technology for the manufacture, use,
sale, offer for sale, and import of one or more Permitted Products; provided, however, IE may grant a sublicense under the rights granted by Codexis to IE under this Section 10.6(a), subject to the provisions of Section 4.7 hereunder
and Section 2.4 of the Codexis-Shell US License Agreement as applied to IE and its Affiliates, mutatis mutandis, for the supply of Biocatalysts manufactured by the sublicensee to specific facilities that use IE Biofuel Process Technology
for the manufacture, use, sale, offer for sale, and import of one or more Permitted Products, but not for sale of Biocatalysts to Third Parties not using such Biocatalysts together with IE Biofuel Process Technology. 
 (ii) In the event that, after the date of the termination of the Codexis-Shell US License Agreement as described in Section
10.6(a)(i), Shell or any of its Affiliates retains or acquires rights with respect to any license rights under any of the Codexis Research Technology and/or the Codexis Introduced Program Technology in the Fuels Field, except for rights and
obligations under Articles 5, 8 and 10 and Sections 2.3, 3.5, 6.2, 7.3 and 7.4 of the Codexis-Shell US License Agreement, for the production of any product other than a Permitted Product, as of the date of the grant of such license, IE shall have a
non-exclusive license right under such Codexis Research Technology and/or such Codexis Introduced Program Technology to produce such product(s) on terms and conditions of the license right granted to Shell or its Affiliates. 
 (iii) Notwithstanding anything to the contrary in this Section 10.6(a), in the event that the Codexis-Shell US License Agreement
terminates in connection with, or subsequent to, the [*] by Shell, or an Affiliate of Shell, directly or indirectly, of the [*], such termination shall have no impact on the rights of IE under the Codexis Introduced Program Technology
and/or the Codexis Research Technology in the Fuels Field in effect immediately prior to such termination. 
 (iv)
Without prejudice to the rights of Codexis or IE under law, termination of the Codexis-Shell US License Agreement shall have no effect on (a) the

  
 [*] Certain
information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 
  

 - 49 - 








 
sublicenses previously granted by or through IE under Introduced Program Technology and Research Technology with respect to (i) any specific operational facility and the products
produced at such facility as of the date of such termination, and/or (ii) any specific facility that is under construction and/or that has been permitted for construction or operation by the relevant governmental agency(ies) with respect to the
products identified in such permit as of the date of such termination, but excluding in each of (i) and (ii), the production of Biocatalysts for any use other than use in direct connection with such specific facility(ies), and (b) the
obligation for IE to make payments to Codexis on behalf of such facilities in accordance with the terms of this Agreement. 
 (b) Rights of Codexis. In the event that the Codexis-Shell US License Agreement terminates and Shell’s rights after such termination are not modified, altered or different than as set forth in Section 9.4(a) of the
Codexis-Shell US License Agreement, IE, effective as of the effective date of such termination, will grant, and hereby grants, to Codexis a non-exclusive license, subject to the terms and conditions of the IE Third Party Agreements, together with a
right to grant sublicense rights, under (i) IE Research Technology and IE Introduced Program Technology, excluding, in each case, any and all Patent Rights within such Technologies, for use in the Fuels Field under terms set forth in the
IE-Shell Canada [*] Agreement as applied to Codexis, mutatis mutandis, and (ii) IE Jointly Invented Research Technology for use in the Fuels Field, such license to be royalty- and payment-free. In addition, the Parties agree that
Codexis may continue to utilize any and all rights granted by IE to Codexis under Patent Rights covering inventions jointly developed by IE and Codexis and, under the terms of this Agreement, owned by IE for any and all purposes expressly granted to
Codexis under the terms of this Agreement. 
 ARTICLE 11 
 GENERAL PROVISIONS 
 11.1 Relationship of the
Parties. The Parties shall perform their obligations under this Agreement as independent contractors and nothing contained in this Agreement shall be construed to make Codexis or IE partners, joint venturers, principals, representatives or
employees of the other. Codexis and IE agree that this Agreement shall not constitute a partnership for tax purposes. In the event, however, that this Agreement was so construed, then Codexis and IE agree to be excluded from the provisions of
Subchapter K of the United States Internal Revenue Code of 1986, as amended. 
 11.2 Assignments. Except as expressly
provided herein, neither this Agreement nor any interest hereunder may be assigned, nor any other obligation delegated, by a Party without the prior written consent of the other Party; provided, however, that each Party shall have the
right to assign this Agreement without consent to an Affiliate of such Party or to any successor in interest to such Party by way of merger, consolidation or other business reorganization or the sale of all or substantially all of its assets. In the
case of any permitted assignment to an Affiliate, the assignee shall assume

 - 50 - 








 
all of the liabilities and obligations of the assigning Party under this Agreement and shall deliver an instrument in writing to each of the other Parties confirming its agreement to do so.
Notwithstanding any such assignment and assumption of this Agreement, the assigning Party shall remain liable, and responsible for, the payment and performance of all such past, present and future liabilities and obligations. This Agreement shall be
binding upon successors and permitted assigns of the Parties. Any assignment not in accordance with this Section 11.2 will be null and void. 
 11.3 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments and to do all such other acts as may be necessary or appropriate in order to carry out the
express provisions of this Agreement.

under the terms of this Agreement in compliance with all applicable import, export, reexport and foreign trade control statutes, laws, regulations, enactments, directives and ordinances of any governmental authority with jurisdiction over such
operations then in effect (“International Trade Laws”) in connection with the performance of its obligations under this Agreement. Each Party shall be responsible for obtaining any necessary authorizations required by International
Trade Laws applicable to any Party’s import, export, reexport or other foreign trade activity in connection with the performance of its obligations under this Agreement. The transfer of any material from a Party to any of the other Parties
shall be conducted in accordance with the terms set forth on Schedule 2.4(b). Each Party will cause these terms to be imposed upon any Affiliate and Third Party from which Information, Technology, materials or services are procured for this
Agreement, including any supplier or subcontractor. This Agreement does not constitute, and shall not be construed to constitute, an agreement by any Party to take or refrain from taking any action, which would constitute non-compliance with any
International Trade Laws applicable to its operations under the terms of this Agreement. 
 11.5 Force Majeure. None of
the Parties shall be liable to the other for failure or delay in the performance of any of its obligations under this Agreement for the time and to the extent such failure or delay is caused by earthquake, riot, civil commotion, war, terrorist acts,
strike, flood, or governmental acts or restriction that is beyond the control of the respective Party. The Party affected by such force majeure will provide the other Parties with full particulars thereof as soon as it becomes aware of the same
(including without limitation its best estimate of the likely extent and duration of the interference with its activities), and will use commercially reasonable efforts to overcome the difficulties created thereby and to resume performance of its
obligations as soon as practicable. If the performance of any obligation under this Agreement is delayed owing to a force majeure for any continuous period of more than ninety (90) days, any of the Parties may terminate this Agreement by giving
to the other Parties not less than ten (10) business days notice in writing. In the event of any force majeure event that delays the performance of a Party under this Agreement, the Term shall automatically be extended for the period of time
that such performance is delayed. Notwithstanding anything to the contrary, the payment of money shall not be subject to this Section 11.5.

limitation this clause) arising out of or related to this Agreement (including without limitation but not limited to any amendments, annexations, and extensions) or the breach thereof shall be settled by consultation between the Parties initiated by
written notice of the Dispute to the other Parties. In the event such consultation does not settle the Dispute within thirty (30) days after written notice of such Dispute, subject to such extension or extensions as the Parties to the Dispute

 ARTICLE II 
 PAYMENT TERMS 
 Section 2.01
Consideration. 
 (a) Intermediates Royalty. IE shall pay to Codexis [*] per U.S. gallon of Royalty-Bearing
Product, where such Royalty-Bearing Product is sold or transferred in exchange for cash or cash equivalent or other consideration to which value can be assigned for use in the Intermediates Field, by either IE or an IE Affiliate or an IE sublicensee
to (i) IE or an IE Affiliate (where IE or such IE Affiliate is the end-user of such Royalty-Bearing Product); or (ii) a Third Party; or (iii) Shell or a Shell Affiliate; in each case, after the First Royalty Sale (in all cases, the
“Intermediates Royalty”); provided that the Intermediates Royalty shall be adjusted on each Royalty Adjustment Date according to changes in the Index as set forth below: 
 (i) The initial adjustment shall be made on the date of First Royalty Sale of the first Royalty-Bearing Product in the Fuels Field
by multiplying the initial Intermediates Royalty by (A/B), where A = the Monthly Index Average during the most recent twelve (12) month period for which final, corrected data are available preceding the date of First Royalty Sale of such first
Royalty-Bearing Product in the Fuels Field, and B = the Monthly Index Average between November 1, 2007 and the most recent date for which final, corrected data are available prior to the date of First Royalty Sale of such Royalty-Bearing
Product. 
 (ii) After the year following the date of First Royalty Sale of the first Royalty-Bearing Product in the
Fuels Field, the Intermediates Royalty shall be adjusted annually on each Royalty Adjustment Date by multiplying the then-current Intermediates Royalty by (X/Y), where X = the Monthly Index Average during the most recent twelve (12) month
period preceding such Royalty Adjustment Date for which final, corrected data are available, and Y = the Monthly Index Average for the twelve

(12) month period beginning sixteen (16) months prior to such Royalty Adjustment Date and ending twenty-seven (27) months prior to such Royalty Adjustment Date. 
 The adjustments to the Intermediates Royalty shall be rounded to the nearest [*]. The Intermediates Royalty obtained after each adjustment shall be
the Intermediates Royalty due from the applicable Royalty Adjustment Date until the subsequent Royalty Adjustment Date. 
 By way of example, if
the Monthly Index Average during the twelve (12) month period preceding the date of First Royalty Sale of the first Royalty-Bearing Product in the Fuels Field for which final, corrected data are available equals two hundred twenty
(220) and the Monthly Index Average between November 1, 2007 and the most recent date for which final, corrected data are available prior to the date of First Royalty Sale of such Royalty-Bearing Product equals two hundred (200), then the
Intermediates Royalty shall be adjusted by an amount equal to two hundred twenty divided by two hundred (220/200), or one point one (1.1), such that the Intermediates Royalty for the subsequent twelve (12) month period shall equal [*]
per U.S. gallon of Royalty-Bearing Product in the Intermediates Field times one point one (1.1), or [*] per U.S. gallon of Royalty-Bearing Product in the Intermediates Field. 
 By way of further example, if the Monthly Index Average during the most recent twelve (12) month period preceding the subsequent Royalty Adjustment Date for which final, corrected data are available
equals two hundred nine (209), and the Monthly Index Average for the twelve (12) month period beginning sixteen (16) months prior to such Royalty Adjustment Date and ending twenty-seven (27) months prior to such Royalty Adjustment
Date equals two hundred twenty (220), then on such Royalty Adjustment Date the Intermediates Royalty shall be adjusted by an amount equal to two hundred nine divided by two hundred twenty (209/220), or zero point nine five (0.95), such that, if the
Intermediates Royalty on such Royalty Adjustment Date is equal to [*] per U.S. gallon, the Intermediates Royalty for the subsequent twelve (12) month period shall equal [*] per U.S. gallon of Royalty-Bearing Product in the
Intermediates Field times zero point nine five (0.95), or [*] per U.S. gallon of Royalty-Bearing Product in the Intermediates Field. 
 (b) Liquid Fuels Royalty. Subject to the last sentence of this paragraph, IE shall pay to Codexis [*] per U.S. gallon of Royalty-Bearing Product, where such Royalty-Bearing Product is sold
or transferred in exchange for cash or cash equivalent or other consideration to which value can be assigned for use in the Liquid Fuels Field, by either IE or an IE Affiliate or a sublicensee to (i) IE or an IE Affiliate (where IE or such IE
Affiliate is the end-user of such Royalty-Bearing Product); or (ii) a Third Party; or (iii) Shell or a Shell Affiliate; in each case, after the First Royalty Sale (in all cases, the “Liquid Fuels Royalty”). Notwithstanding the
foregoing, IE and Codexis acknowledge and agree that as of the Effective Date, (A) there is insufficient data available to definitively determine the appropriate royalty rate for the manufacture, use, offer for sale, sale or importation of
Royalty-Bearing Product(s) in the Liquid Fuels Field and (B) Codexis and Shell US have therefore agreed to engage in good faith negotiations regarding such royalty on or before [*]. In the event that Codexis and Shell US agree on a
different rate for such royalty, Codexis and Shell US shall provide written notice

  
 [*] Certain
information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

thereof to IE and such different royalty rate shall be deemed to be the Liquid Fuels Royalty for purposes of this Section 2.01(b) of this Schedule 5.1(c); provided, however,
that, if Codexis and Shell US are unable to agree upon the Liquid Fuels Royalty after such negotiations, the royalty rate shall equal [*] per U.S. gallon of Royalty-Bearing Product; provided, further, that the Liquid Fuels
Royalty shall be adjusted on each Royalty Adjustment Date according to changes in the Index as set forth below. 
 (i)
The initial adjustment shall be made on the date of First Royalty Sale of the first Royalty-Bearing Product in the Fuels Field by multiplying the initial Liquid Fuels Royalty by (A/B), where A = the Monthly Index Average during the most recent
twelve (12) month period for which final, corrected data are available preceding the date of First Royalty Sale of such first Royalty-Bearing Product in the Fuels Field, and B = the Monthly Index Average between November 1, 2007 and the
most recent date for which final data are available prior to the date of First Royalty Sale of such Royalty-Bearing Product. 
 (ii) After the year following the date of First Royalty Sale of the first Royalty-Bearing Product in the Fuels Field, the Liquid Fuels Royalty shall be adjusted annually on each Royalty Adjustment Date by multiplying the then-current
Liquid Fuels Royalty by (X/Y), where X = the Monthly Index Average during the most recent twelve (12) month period preceding such Royalty Adjustment Date for which final, corrected data are available, and Y = the Monthly Index Average for the
twelve (12) month period beginning sixteen (16) months prior to such Royalty Adjustment Date and ending twenty-seven (27) months prior to such Royalty Adjustment Date. 
 The adjustments to the Liquid Fuels Royalty shall be rounded to the nearest [*]. The Liquid Fuels Royalty obtained after each adjustment shall be the Liquid Fuels Royalty due from the applicable
Royalty Adjustment Date until the subsequent Royalty Adjustment Date. 
 By way of example, if the Monthly Index Average during the twelve
(12) month period preceding the date of First Royalty Sale of the first Royalty-Bearing Product in the Fuels Field for which final, corrected data are available equals two hundred twenty (220) and the Monthly Index Average between
November 1, 2007 and the most recent date for which final, corrected data are available prior to the date of First Royalty Sale of such Royalty-Bearing Product equals two hundred (200), then the Liquid Fuels Royalty shall be adjusted by an
amount equal to two hundred twenty divided by two hundred (220/200), or one point one (1.1), such that the Liquid Fuels Royalty for the subsequent twelve (12) month period shall equal [*] per U.S. gallon of Royalty-Bearing Product in the
Liquid Fuels Field times one point one (1.1), or [*] per U.S. gallon of Royalty-Bearing Product in the Liquid Fuels Field. 
 By way of
further example, if the Monthly Index Average during the most recent twelve (12) month period preceding the subsequent Royalty Adjustment Date for which final, corrected data are available equals two hundred nine (209), and the Monthly Index
Average for the twelve (12) month period beginning sixteen (16) months prior to such Royalty Adjustment Date and ending twenty-seven (27) months prior to such Royalty Adjustment Date equals two hundred twenty (220), then on such
Royalty Adjustment

Date the Liquid Fuels Royalty shall be adjusted by an amount equal to two hundred nine divided by two hundred twenty (209/220), or zero point nine five (0.95), such that, if the Liquid Fuels
Royalty on such Royalty Adjustment Date is equal to [*] per U.S. gallon, the Liquid Fuels Royalty for the subsequent twelve (12) month period shall equal [*] per U.S. gallon of Royalty-Bearing Product in the Liquid Fuels Field
times zero point nine five (0.95), or [*] per U.S. gallon of Royalty-Bearing Product in the Liquid Fuels Field. 
 (c)
Lubricants Royalty. IE and Codexis acknowledge and agree that (i) as of the Effective Date, there is insufficient data available to definitively determine the appropriate royalty rate for the manufacture, use, offer for sale, sale or
importation of Royalty-Bearing Product(s) in the Lubricants Field and (ii) Codexis and Shell US have therefore agreed to engage in good faith negotiations regarding such royalty. Upon agreement of such royalty rate between Codexis and Shell US
(including without limitation any periodic adjustments in such royalty rate, if applicable), Codexis and Shell US shall provide written notice thereof to IE and such royalty rate shall be deemed to be the royalty that IE shall pay to Codexis for
each Royalty-Bearing Product in the Lubricants Fields, where such Royalty-Bearing Product is sold or transferred in exchange for cash or cash equivalent or other consideration to which value can be assigned for use in the Lubricants Field, by either
IE or an IE Affiliate or an IE sublicensee to (A) IE or an IE Affiliate (where IE or such IE Affiliate is the end-user of such Royalty-Bearing Product); or (B) a Third Party; or (C) Shell or a Shell Affiliate; in each case, after the
First Royalty Sale (in all cases, the “Lubricants Royalty”). 
 (d) Notice of First Royalty Sale. IE
shall notify Codexis promptly, in writing, of the date of the First Royalty Sale for each Royalty-Bearing Product and, in the case where such First Royalty Sale is made by a sublicensee of IE or an IE Affiliate, the identity of such sublicensee.

 SCHEDULE 11.9 
 ARBITRATION RULES 
 1. Initiation of Arbitration. Upon notice
by any Party to this Agreement to the others (a “Notice to Arbitrate”), any Dispute under this Agreement shall be resolved by arbitration to be held in accordance with the then current Comprehensive Arbitration Rules and Procedures
(“Rules”) of JAMS (“Arbitration Authority”) and this provision. The arbitration shall be held in Denver, Colorado and, unless otherwise agreed by the Parties, all proceedings, hearings and steps in the arbitration
shall take place in Denver, Colorado. The language to be used in the arbitration proceedings shall be English. 
 2. Composition and
Selection of Arbitral Tribunal. The arbitral tribunal (the “Arbitral Tribunal”) shall be composed of one (1) arbitrator, to be selected as follows. Within five (5) business days following delivery of a Notice to
Arbitrate, each Party involved in the dispute shall submit to the Arbitration Authority a one-page summary of the dispute. Promptly thereafter, the Arbitration Authority shall prepare a list of ten (10) prospective arbitrators (the
“Arbitration List”), each of whom shall be independent of the Parties (including any Party that is not involved in the dispute) and shall have appropriate expertise relating to the subject matter of the dispute. The Parties agree
that an arbitrator does not have to be based in Denver to be eligible for inclusion on the Arbitration List. Each Party involved in the arbitration shall be entitled to strike the names of two persons from the Arbitration List by identifying such
names to the Arbitration Authority within ten (10) business days following such Party’s receipt of the Arbitration List. Promptly after the Parties have exercised (or declined to exercise) their rights to strike names from the Arbitration
List, the Arbitration Authority shall appoint the sole arbitrator from the arbitrators who have not been stricken by any of the Parties to the dispute. 
 3. Confidentiality of Proceedings. The arbitration proceedings shall be deemed the Confidential Information of all Parties involved in the arbitration and shall be treated by each Party in
accordance with Article 7 of the Agreement. Subject to the requirements and limitations of Article 7 of the Agreement, any Confidential Information provided by a Party during the arbitration or by any witness presented by such Party shall be treated
as the Confidential Information of the disclosing Party and no Party shall disclose or use such Confidential Information beyond the scope of the arbitration proceeding. 
 4. Powers of Arbitral Tribunal. By submitting to arbitration under these Rules, the Parties shall be taken to have conferred on the Arbitral Tribunal the subject matter jurisdiction and powers set
out in this Schedule 11.8. The Arbitral Tribunal will exercise subject matter jurisdiction and the powers as provided in the Rules and this Schedule 11.8. Without limiting the powers of the Arbitral Tribunal, the Parties agree that the Arbitral
Tribunal may: 
 (a) proceed in the arbitration even if a Party to the arbitration fails or refuses to comply with the Rules or
with the Arbitral Tribunal’s orders or directions, or to attend any meeting or hearing, but only after giving that Party written notice that the Arbitral Tribunal intends to do so;

 (b) receive and take into account such written and oral evidence, including without
limitation, written interrogatories, tendered by the Parties to the arbitration as the Arbitral Tribunal determines is relevant, whether or not strictly admissible in law; 
 (c) order the Parties to the arbitration and their Affiliates to produce to the Arbitral Tribunal, and to each other for inspection, and to
supply copies of, any documents or classes of documents in the possession or control of such Party or any of their Affiliates which the Arbitral Tribunal determines to be relevant (taking into account such submissions of the Parties as the Arbitral
Tribunal may determine to hear); and 
 (d) order the Parties to the arbitration and their Affiliates to preserve evidence in
any manner the Arbitral Tribunal may determine to be necessary, including by way of the preservation or storage of any property, documents or things under the control of the Parties. 
 5. Awards. The arbitrator(s) shall determine the claim of the Parties and render a final award in accordance with the substantive law of the State of New York, excluding the conflicts provisions of
such law. The Arbitral Tribunal shall render an opinion within fifteen (15) business days after the final hearing before the Arbitral Tribunal, and within six (6) months from the appointment of the Arbitral Tribunal, whichever occurs last;
provided, however, that this six-month deadline may be extended by agreement of the Parties to the arbitration or upon an express finding by the Arbitral Tribunal that it would be impracticable to meet this deadline. Any and all awards of the
Arbitral Tribunal shall be made in writing in accordance with the Rules and shall be final and binding on the Parties. The Arbitral Tribunal shall set forth the reasons for the award in writing. Each of the Parties expressly excludes all and any
rights of appeal from all and any awards. Any award may be entered or enforced in any court of competent jurisdiction against a Party named in the award. All and any awards may include an award of costs (including, without limitation, the fees of
counsel and any other professional advisors retained by the Parties in connection with the dispute), which shall be fixed by the Arbitral Tribunal. The terms of this Schedule 11.8 shall not limit any obligations of a Party to defend, indemnify or
hold harmless another Party against court proceedings or other claims, losses damages or expenses. Notwithstanding anything herein to the contrary, a Party may seek a temporary restraining order or a preliminary injunction from any court of
competent jurisdiction in order to prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the decision of the arbitrator on the ultimate merits of any dispute.
