2.1.2

During the TERM of this AGREEMENT, CODEXIS shall be the supplier of a minimum of [***]% of the SUBSTANCE requirements by MERCK; provided, however, there are no supply disruptions or compliance issues with the CODEXIS supplied SUBSTANCE pursuant to this Section 2.1.2. In the event MERCK identifies a SUBSTANCE compliance issue with respect to the quality and/or DELIVERY of SUBSTANCE, MERCK shall notify CODEXIS immediately of such issue, and the PARTIES shall discuss such issue in good faith.

In this case, the [***]% minimum SUBSTANCE supply commitment to CODEXIS by MERCK will immediately cease to be in effect until CODEXIS resolves such SUBSTANCE compliance issue to MERCK's reasonable satisfaction, at which point, such [***]% minimum requirement shall be reinstated at a reasonable time as MERCK may have made commitments to other suppliers to mitigate the risk.

2.1.3

During the TERM of this AGREEMENT, MERCK has the right to develop at any time a direct SUBSTANCE MANUFACTURER for not more than [***] percent ([***]%) of MERCK’s SUBSTANCE demand. In such case, MERCK shall pay CODEXIS [***] within [***] days of the successful completion of MANUFACTURE of SUBSTANCE by such SUBSTANCE MANUFACTURER at the intended commercial scale, and in exchange CODEXIS agrees to provide all appropriate and necessary technical support for the SUBSTANCE MANUFACTURER qualification within six (6) months of MERCK's request. MERCK will negotiate the price for such SUBSTANCE directly with the SUBSTANCE MANUFACTURER and CODEXIS will not be involved in any part of the commercial agreement. Subject to Section 15.1, MERCK shall not acquire any SUBSTANCE pursuant to this Section 2.1.3 from any of the PRIMARY SUBSTANCE MANUFACTURER, SECONDARY SUBSTANCE MANUFACTURER, TERTIARY SUBSTANCE MANUFACTURER or any proposed PRIMARY SUBSTANCE MANUFACTURER, SECONDARY SUBSTANCE MANUFACTURER or TERTIARY SUBSTANCE MANUFACTURER. CODEXIS has identified [***] as the PRIMARY SUBSTANCE

MANUFACTURER and [***] as the SECONDARY SUBSTANCE MANUFACTURER.

2.1.4

The PARTIES agree that CODEXIS has identified and qualified [***] to be the current SUBSTANCE MANUFACTURER and [***] is defined as the "PRIMARY SUBSTANCE MANUFACTURER". Pursuant to an agreement entered into on or about the EFFECTIVE DATE, [***] has agreed to MANUFACTURE SUBSTANCE for CODEXIS for three (3) years with the term of such agreement automatically renewing for a period of one (1) year after the initial three (3)-year term expires unless either [***] or CODEXIS delivers the other party a notice of non-renewal twelve (12) months prior to the end of the initial three (3)-year term or the then current renewal term.

2.1.5

The PARTIES agree that within six (6) months of notification from MERCK, CODEXIS will have the obligation to identify and qualify a second SUBSTANCE MANUFACTURER defined as "SECONDARY SUBSTANCE MANUFACTURER" for the MANUFACTURE of SUBSTANCE to be made on its behalf for MERCK. MERCK shall pay CODEXIS a one time [***] fee upon the qualification and successful Quality Audit by MERCK of the "SECONDARY SUBSTANCE MANUFACTURER". Whether a Quality Audit was in fact successful or not shall be determined at the reasonable discretion of MERCK. MERCK has the right to perform a Quality Audit of such SECONDARY SUBSTANCE MANUFACTURER at any time to ensure the SUBSTANCE is MANUFACTURED in accordance with appropriate quality controls as agreed upon by the Parties prior to commencement of MANUFACTURE of SUBSTANCE; provided, that MERCK shall pay to CODEXIS the [***] fee referred to in the second sentence of this Section 2.1.5 within [***] months of MERCK’s initial receipt of SUBSTANCE from the SECONDARY SUBSTANCE MANUFACTURER, regardless if such qualification and Quality Audit were performed or completed, unless such qualification failed or the Quality Audit was unsuccessful (in which event, MERCK shall pay the [***] fee when the qualification and successful Quality Audit do occur). If the SECONDARY SUBSTANCE MANUFACTURER is not found acceptable by MERCK, then CODEXIS shall use commercially reasonable efforts to ensure the SECONDARY SUBSTANCE MANUFACTURER rectifies all deficiencies and complies with the applicable quality standards. CODEXIS will be solely responsible for ensuring the SECONDARY SUBSTANCE MANUFACTURER meets all applicable standards. MERCK shall not be obligated to provide any financial or other support to the SECONDARY SUBSTANCE MANUFACTURER to rectify any quality deficiencies but may, at its

sole discretion, elect to participate in any corrective action should it desire to do so.

2.1.6

No sooner than six (6) months after the qualification of the SECONDARY SUBSTANCE MANUFACTURER, MERCK shall have the right but not the obligation to request CODEXIS to qualify a third SUBSTANCE MANUFACTURER to be defined as "TERTIARY SUBSTANCE MANUFACTURER". MERCK shall pay CODEXIS a one time fee of [***] upon the qualification and successful Quality Audit by MERCK of the TERTIARY SUBSTANCE MANUFACTURER. Whether a Quality Audit was in fact successful or not shall be determined at the reasonable discretion of MERCK. MERCK has the right to perform a Quality Audit of such TERTIARY SUBSTANCE MANUFACTURER at any time to ensure the SUBSTANCE is MANUFACTURED in accordance with appropriate quality controls as agreed upon by the PARTIES prior to commencement of MANUFACTURE of SUBSTANCE; provided, that MERCK shall pay to CODEXIS the [***] fee referred to in the second sentence of this Section 2.1.6 within [***] months of MERCK’s initial receipt of SUBSTANCE from the TERTIARY SUBSTANCE MANUFACTURER, regardless if such qualification and Quality Audit were performed or completed, unless such qualification failed or the Quality Audit was unsuccessful (in which event, MERCK shall pay the [***] fee when the qualification and successful Quality Audit do occur). If the TERTIARY SUBSTANCE MANUFACTURER is not found acceptable by MERCK, then CODEXIS shall use commercially reasonable efforts to ensure the SUBSTANCE MANUFACTURER rectifies all deficiencies and complies with the applicable quality standards. CODEXIS will be solely responsible for ensuring the TERTIARY SUBSTANCE MANUFACTURER meets all applicable standards. MERCK shall not be obligated to provide any financial or other support to the TERTIARY SUBSTANCE MANUFACTURER to rectify any quality deficiencies but may, at its sole discretion, elect to participate in any corrective action should it desire to do so.


2.2	FIRM ORDERS, Forecasts and Inventory.


2.2.1	FIRM ORDERS, Forecasts for SUBSTANCE and Inventory.


2.2.1.1	Within [***] business days of the beginning of each QUARTER during the TERM, MERCK shall make available to CODEXIS, upon Codexis written request (email is acceptable), a good faith forecast reflecting MERCK’s, its AFFILIATES’, and its THIRD PARTY SUPPLIERS’ requirements, if any, for SUBSTANCE for each of the following four QUARTERS by

setting forth the quantities of SUBSTANCE to be supplied, broken down by QUARTER. It is understood and agreed that estimates shall not constitute commitments to take DELIVERY of SUBSTANCE or FIRM ORDERS unless such forecasts are specified in writing by MERCK as binding. All projected order dates, quantities and shipping dates set forth in the forecasts delivered pursuant to this Section 2.2.1.1 shall be binding on MERCK in respect of the requirements set forth for the two full QUARTERS immediately following the delivery of each such forecast; provided that, no forecasts shall be binding until the first time MERCK obtains approval by an applicable regulatory AGENCY in any country in the TERRITORY to use SUBSTANCE in the MANUFACTURE of COMPOUND.

2.2.1.2

At least [***] days prior to the beginning of each QUARTER during the TERM, MERCK shall place a FIRM ORDER for its requirements of SUBSTANCE for such QUARTER. MERCK may also place a FIRM ORDER at any time during the TERM of this AGREEMENT; provided that such FIRM ORDER is submitted at least ninety (90) days prior to the earliest DELIVERY date set forth in such FIRM ORDER. Each FIRM ORDER shall specify the following:


•	quantity of SUBSTANCE ordered;


•	the SUBSTANCE price based on Attachment 3;


•	the required DELIVERY date(s);


•	the ship-to address;


•	the specific packaging amount;


•	shipping conditions;


•	for each quantity of SUBSTANCE, MERCK shall, upon CODEXIS’ written request, provide any documentation necessary to establish any difference in pricing for SUBSTANCE ordered; and

Notwithstanding anything herein to the contrary, CODEXIS shall not reject the first FIRM ORDER placed under this Agreement so long as the quantity of SUBSTANCE ordered thereunder is not greater than [***] and the delivery date for such SUBSTANCE is not less than [***] from the date such FIRM ORDER is received by CODEXIS. In no event shall CODEXIS be obligated to satisfy any requirements for quantities of SUBSTANCE in any FIRM ORDER for any QUARTER placed by Merck following the first FIRM ORDER (i) in excess of the estimate for such QUARTER as set forth in the most recent forecast delivered to CODEXIS pursuant to

Section 2.2.1.1 or (ii) in excess by more than [***] percent ([***]%) of the estimate for such QUARTER as set forth in the forecast delivered to CODEXIS pursuant to Section 2.2.1.1 immediately before the forecast described in clause (i) above. In addition, within [***], MERCK shall deliver FIRM ORDERS for SUBSTANCE for the remainder of the then-current QUARTER and each of the following [***] QUARTERS broken down by QUARTER. For such FIRM ORDERS, CODEXIS shall have [***] business days to accept or reject such FIRM ORDERS and if CODEXIS does not respond within such [***] day period, then the FIRM ORDER is deemed rejected.

2.2.1.3

Should MERCK deliver a FIRM ORDER requesting that CODEXIS supply SUBSTANCE in excess of MERCK’s most recent estimate of its requirements made available to CODEXIS pursuant to Section 2.2.1.1, CODEXIS shall use reasonable commercial efforts to meet such request for SUBSTANCE; however, in the event that CODEXIS will not be able to meet such request, CODEXIS’ failure to supply such excess amounts shall not be a breach of CODEXIS’ obligations under this AGREEMENT.

2.2.1.4

MERCK may cancel or defer any portion of a FIRM ORDER for SUBSTANCE which exceeds the forecast for such QUARTER, in whole or in part, without penalty, provided that such cancellation or deferment notice is in writing and received by CODEXIS at least [***] days prior to the scheduled DELIVERY date for SUBSTANCE and MERCK reimburses CODEXIS for all reasonable costs and expenses incurred by CODEXIS in the production of such cancelled or deferred portion prior to receipt of such notice.


2.2.1.5	CODEXIS shall DELIVER each accepted FIRM ORDER for SUBSTANCE on or before the date(s) specified in such FIRM ORDER by MERCK. No DELIVERY of SUBSTANCE shall be made more than [***] business days in advance of the date specified for DELIVERY in such FIRM ORDER without MERCK's approval. CODEXIS’ site of MANUFACTURE shall be indicated on documents accompanying each shipment of SUBSTANCE.


2.2.1.6	CODEXIS shall cause each shipment of SUBSTANCE to be DELIVERED to MERCK with not less than [***] months of the then-current shelf life remaining on such shipment of SUBSTANCE; provided, however, that after the shelf life of

SUBSTANCE is extended to [***] months or beyond, CODEXIS shall cause each shipment of SUBSTANCE to be DELIVERED to MERCK with not less than [***]% of the then-current shelf life remaining on such shipment of SUBSTANCE. CODEXIS will perform stability tests through at least thirty six (36) months.

2.2.1.7

FIRM ORDERS will be made on such form of purchase order or document as MERCK may specify from time to time in writing, provided that the terms and conditions of this AGREEMENT shall be controlling over any terms and conditions included in any FIRM ORDER. Any FIRM ORDER containing a term or condition that is in addition to, different from or contrary to the terms and conditions of this AGREEMENT shall be void with respect to such additional, different or contrary term or condition unless consented to in writing by CODEXIS.


2.2.1.8	CODEXIS shall cause the SUBSTANCE MANUFACTURER(s) to at all times have in inventory not less than [***]% of the projected quantities of SUBSTANCE to be supplied to MERCK over a four-QUARTER period as set forth in the most recently delivered forecast pursuant to Section 2.2.1.1.


2.2.1.9	The LEAD TIME is shown on the table below:



Supplier	LEAD TIME [***]	LEAD TIME [***]	LEAD TIME [***]	LEAD TIME [***]	Max Capacity	Comment
[***]	[***]	[***]	[***]	[***]	[***]	Standard operation
[***]	[***]	[***]	[***]	[***]	[***]	*Demonstrated with augmented staff

TERTIARY SUBSTANCE MANUFACTURER	[***]	[***]	[***]	[***]	[***]
Total	[***]	[***]	[***]	[***]	[***]

For the avoidance of doubt, the table above is for planning purposes only and it reflects the current capacity and throughput of the SUBSTANCE MANUFACTURERS. For example, [***] can supply [***] Kgs. of SUBSTANCE with a [***]-month LEAD TIME. Once the LEAD TIME increases to [***] months, [***] can supply [***] Kgs. of SUBSTANCE and with a LEAD TIME of [***] months, [***] can supply [***] Kgs. of SUBSTANCE.

At CODEXIS’ request, but not more than once per year, the $/kg of SUBSTANCE as listed in the schedule in TABLE 1 on ATTACHMENT 3 will be adjusted based on the latest ratio of COMPOUND SUBSTRATE to PRODUCT.

The following examples show the calculation of ANNUAL LICENSE FEES AND SUBSTANCE FEES. The examples are for demonstration purposes only and remain subject to applicable adjustment under TABLE 1 on ATTACHMENT 3.

Example # 1

[***]

LICENSE FEE (Attachment 2) = [***]

SUBSTANCE FEE (Attachment 3) = ([***] Kgs X [***]% X [***]) X [***] + ([***] Kg's X [***]% X [***]) X [***] = [***] + [***] = [***]



[***]	PRODUCT Volume (kg)	[*] PRODUCT [*]	SUBSTANCE [***]	SUBSTANCE [***]	SUBSTANCE Fee
[***]	[***]	[***]	[***]	[***]	[***]
[***]	[***]	[***]	[***]	[***]	[***]

Total amount paid to CODEXIS = [***] + [***] = [***]

Example # 2

[***]


•	Incremental PRODUCT MANUFACTURED with SUBSTANCE = [*] kilograms (Year 1) + [] kilograms (Year 2) = [**] kilograms

4.2

Reconciliation. Within [***] days following the end of each CALENDAR YEAR, the PARTIES shall review the report provided by MERCK to CODEXIS as set forth in Section 17.2 of this AGREEMENT in order to determine if the SUBSTANCE FEES paid by MERCK to CODEXIS during such CALENDAR YEAR were calculated in conformance with this AGREEMENT. Any underpayment or overpayment by MECK will be reflected on the invoice for its next FIRM ORDER. In addition, the PARTIES may mutually agree to

engage in such reconciliation at any time during the TERM for any period of time, and MERCK shall supply any information or documentation requested by CODEXIS for such reconciliation.

4.3

Minimum Demand. For forecast purposes only, MERCK expects to purchase a minimum of [***] of SUBSTANCE from CODEXIS, its AFFILIATES, or THIRD PARTY SUPPLIERS per CALENDAR YEAR, provided the demand for SUBSTANCE exists, as subject to pending regulatory approvals worldwide. This Section 4.3 provides a non-binding forecast based on current SUBSTANCE LOADING FACTORS and COMPOUND cycle time and yields and does not commit MERCK to any minimum purchase or create any financial obligation of MERCK to CODEXIS.


4.4	Payments in U.S. Dollars. All payments required pursuant to this Article 4.0 are based on U.S. dollars.


5.0	USE OF SUBSTANCE


5.1	Efficiency of SUBSTANCE.

21.0	DISPUTE RESOLUTION

21.1

The PARTIES shall attempt to amicably resolve any dispute arising out of or relating to this AGREEMENT. In the event that said negotiations are not successful within thirty (30) days after the occurrence of such dispute, it shall be finally resolved through arbitration before three (3) arbitrators, provided that such dispute is not an Excluded Claim. Such arbitration shall take place in Chicago, Illinois, the United States of America and shall proceed in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”). Within fifteen (15) calendar days of either PARTY making a demand for arbitration, MERCK and CODEXIS shall each select one (1) arbitrator. A third arbitrator shall be selected by the arbitrators selected by the PARTIES within thirty (30) days after such arbitrators are appointed. In the event that either PARTY shall fail to appoint its arbitrator, or the two arbitrators selected by the PARTIES fail to appoint the third arbitrator, in either case within the prescribed time period, then either PARTY may apply to the AAA for the appointment of such arbitrator. The determination of a majority of the panel of arbitrators shall be the decision of the arbitrators and shall be binding regardless of whether one of the PARTIES fails or refuses to participate in the arbitration. Each PARTY

shall pay for the arbitrator it selects with the cost of the third arbitrator being split equally between the PARTIES. All other costs shall also be split equally between the PARTIES. Either PARTY may enter any arbitration award in any court having jurisdiction or may make application to any such court for a judicial acceptance of the award and order of enforcement, as the case may be. As used in this Section 21.1, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a) the validity or infringement of a patent, trademark or copyright; or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

Notwithstanding anything to the contrary, each PARTY may seek injunctive relief, including without limitation 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(s) on the ultimate merits of any dispute, controversy or claim.

For all FIRM ORDERS for which the cost of SUBSTANCE exceeds FIVE-HUNDRED FIFTY THOUSAND DOLLARS ($550,000.00), or for construction of any public facility ONE MILLION DOLLARS ($1,000,000.00), CODEXIS shall, use its commercially reasonable efforts to include FAR 52.219-8 in all SUBCONTRACTOR agreements that offer opportunities for the supply of raw materials used for the MANUFACTURE of SUBSTANCE; provided, that such raw materials are of equivalent quality and cost.

For all FIRM ORDERS for which the cost of SUBSTANCE exceeds FIVE MILLION DOLLARS ($5,000,000), CODEXIS shall, use its commercially reasonable efforts to also comply with the following; provided, however, that to the extent there is any conflict between FAR 52.219-8 and the following, the requirements of FAR 52.219-8 will take precedence:

MERCK is committed to equal employment and supplier diversity. As part of this commitment, it is MERCK’s policy that DIVERSE SUBCONTRACTORS have the maximum practicable opportunity to participate in the performance of work and services for MERCK and MERCK’s suppliers (the “MERCK DIVERSITY POLICY”). The term “DIVERSE SUBCONTRACTORS” shall mean those suppliers and contractors that comprise “HUBZone small business concerns” and “small disadvantaged business concerns,” each as defined in FAR 52.219-8, and “VETERAN-OWNED BUSINESS CONCERNS,” “WOMEN-OWNED BUSINESS CONCERNS,” “MINORITY-OWNED BUSINESS CONCERNS,” and “GAY AND LESBIAN-OWNED BUSINESS CONCERNS.”

24.4 In the event CODEXIS is determined to be a United States domestic manufacturer of SUBSTANCE and solely with respect to FIRM ORDERS for which the cost of SUBSTANCE exceeds Five Million DOLLARS ($5,000,000), CODEXIS shall use its commercially reasonable efforts to establish and conduct a diversity program and diversity procedures that will enable DIVERSE SUBCONTRACTORS to be considered fairly as SUBCONTRACTORS under this AGREEMENT (the “SUPPLIER DIVERSITY PROGRAM”). In such event, as part of the SUPPLIER DIVERSITY PROGRAM, CODEXIS shall, to the extent practicable, inter alia: (1) assist DIVERSE SUBCONTRACTORS by arranging contracting opportunities, quantities, specifications, and delivery schedules so as to facilitate their participation; (2) Provide adequate and timely consideration of the potentialities of DIVERSE SUBCONTRACTORS in all “make-or-buy” decisions; (3) designate a liaison manager who shall be responsible for interfacing with and administering subcontracting opportunities for DIVERSE SUBCONTRACTORS; (4) counsel and discuss subcontracting opportunities with representatives of DIVERSE SUBCONTRACTORS; (5) maintain records showing (a) procedures adopted by CODEXIS to comply with the MERCK DIVERSITY POLICY, including the establishment of a source list of DIVERSE SUBCONTRACTORS, (b) awards of agreements to DIVERSE SUBCONTRACTORS on the source list, and (c) specific efforts to identify and award agreements to DIVERSE SUBCONTRACTORS; and (6) cooperate with MERCK representatives in any studies and surveys of the

24.5 In the event CODEXIS is determined to be a United States domestic manufacturer of SUBSTANCE and solely with respect to FIRM ORDERS for which the cost of SUBSTANCE exceeds Five Million DOLLARS ($5,000,000), CODEXIS shall use its commercially reasonable efforts to engage DIVERSE SUBCONTRACTORS for the MANUFACTURE of SUBSTANCE and/or provide raw materials needed for the MANUFACTURE of SUBSTANCE representing at least five percent (5%) of the aggregate cost of the total raw material cost of SUBSTANCE for the CALENDAR YEAR. In such event, CODEXIS shall, to the extent practicable, provide MERCK with quarterly reports identifying the DIVERSE SUBCONTRACTORS and the total paid in the subject quarter to each SUBCONTRACTOR. Said reports shall, to the extent practicable, be submitted via MERCK’s online 2^nd Tier Reporting System and shall include both “direct” and “indirect” DIVERSE SUBCONTRACTOR payments.

24.6 Notwithstanding anything herein to the contrary, any non-compliance with this Article 24.0 by CODEXIS shall not be deemed a material breach of this AGREEMENT. In the event MERCK identifies any such non-compliance, the PARTIES shall discuss in good faith each PARTY’s compliance concerns.

This Mutual Confidentiality Agreement (this “AGREEMENT”) entered into by and between MERCK SHARP & DOHME CORP., having a place of business at One Merck Drive, Whitehouse Station, New Jersey 08889-0100 ("MERCK") and CODEXIS, INC., having an address at 200 Penobscot Drive, Redwood City, California 94063 ("SUPPLIER") confirms the terms under which a PPARTY (as defined in that certain Sitagliptin Catalyst Supply Agreement dated as of the date hereof between MERCK and SUPPLIER (the “SUPPLY AGREEMENT”; capitalized terms used herein and not otherwise defined shall have the meaning herein as therein defined) or its AFFILIATES has disclosed or may hereafter disclose to the other PARTY certain confidential and proprietary information for the sole purpose of enabling SUPPLIER to analyze, evaluate, develop, process, utilize, and/or manufacture, including intermediates, COMPOUND, for MERCK and/or its AFFILIATES and for performing under the SUPPLY AGREEMENT. MERCK and SUPPLIER agree that any and all information, know-how, and data, whether oral, written, or graphical, that is disclosed or provided by MERCK or its AFFILIATES to SUPPLIER or by SUPPLIER to MERCK or its AFFILIATES (including any analysis, products, or conclusions drawn or derived therefrom), whether labeled as confidential/proprietary, or that may be derived from or related to any visits by personnel of one PARTY to the location of the other or that may be otherwise known to one PARTY through its visits or contacts with the other (hereinafter individually and collectively referred to as "INFORMATION") shall be disclosed and used by the PARTIES subject to the following terms and conditions:

Except as set forth in the SUPPLY AGREEMENT, MERCK and SUPPLIER shall keep all INFORMATION of the other PPARTY in confidence and will not, without the disclosing PARTYPARTY's prior written consent, disclose any INFORMATION of the disclosing PARTY to any person or entity, except those officers, employees, agents, or AFFILIATES of the receiving PARTY who directly require the INFORMATION. Each officer, employee, agent, or AFFILIATE to whom INFORMATION is to be disclosed shall be advised by the receiving PPARTY of the terms of this AGREEMENT and shall be bound by the confidentiality and non-use obligations herein, mutatis mutandis. Both PARTIES shall take all reasonable precautions to prevent INFORMATION of the other PARTY from being disclosed to any unauthorized person or entity.

Except as set forth in the SUPPLY AGREEMENT, MERCK and SUPPLIER shall not use, either directly or indirectly, any INFORMATION of the other PARTY disclosed to it hereunder, irrespective of whether such INFORMATION is disclosed prior to the effective date of this AGREEMENT, for any purpose other than for the sole purpose of performing its obligations under the SUPPLY AGREEMENT without the disclosing PARTY’s prior written consent.


3.	The obligations of confidentiality set forth herein shall not apply to any INFORMATION that is:


(a)	lawfully possessed at any time by the receiving PARTY prior to receipt from the disclosing PARTY, as evidenced by the receiving PARTY’s written records; or


(b)	published or available to the general public otherwise than through the receiving PARTY’s breach of this AGREEMENT, or its breach of any other obligation of confidentiality; or


(c)	obtained by the receiving PARTY from a THIRD PARTY with a valid right to disclose such INFORMATION, provided that said THIRD PARTY is not under a confidentiality obligation to the disclosing PARTY; or


(d)	independently developed by employees or agents of the receiving PARTY who had no knowledge of the disclosing PARTY’s INFORMATION, as evidenced by the receiving PARTY’s written records.

Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the receiving PARTY unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the receiving PARTY.

Except as set forth in the SUPPLY AGREEMENT, all INFORMATION, without limitation, shall remain the property of the disclosing PARTY. Except as set forth in the SUPPLY AGREEMENT, neither PARTY shall acquire any license or any other intellectual property interest in any INFORMATION disclosed to it by the disclosing PARTY. Except as set forth in the SUPPLY AGREEMENT, disclosure of INFORMATION shall not result in any obligation to grant the receiving PARTY any right in and to said INFORMATION.


5.	SUPPLIER shall not perform or have performed any toxicity testing on COMPOUND, or any MERCK-designated key raw material used to manufacture COMPOUND, unless and until SUPPLIER provides (i) written notice to MERCK and (ii) an opportunity for the PARTIES to consult on the necessity and/or desirability of such toxicity testing.

Except as set forth in the SUPPLY AGREEMENT, upon the written request of the disclosing PARTY, the receiving PARTY shall immediately either return to the disclosing PARTY, or destroy, all INFORMATION of the disclosing PARTY, in accordance with the instructions of the disclosing PARTY, including all notes, summaries, and translations that have been made regarding such INFORMATION, and all copies of the foregoing. In the event destruction is requested by the disclosing PARTY, the receiving PARTY shall certify such destruction in writing.

In the event that the PARTY receiving any INFORMATION is required by judicial or administrative process to disclose any or all of the INFORMATION, said PARTY shall promptly notify the disclosing PARTY and allow the disclosing PARTY a reasonable time and opportunity to oppose such process before disclosing any INFORMATION. Notwithstanding anything in this AGREEMENT to the contrary, MERCK shall have the right to disclose any INFORMATION to a regulatory agency to the extent required or requested by such agency in connection with any regulatory filing, inspection or otherwise.

Any disclosure made pursuant to this Section 7 shall not affect the confidential nature of the disclosed INFORMATION (except to the extent the disclosure was made publicly available, such as but not limited to filings with the United States Securities and Exchange Commission, in which case such disclosed INFORMATION shall no longer be deemed confidential).

No agency or partnership relationship between MERCK and SUPPLIER, either express or implied, shall be created by this AGREEMENT. Except as set forth in the SUPPLY AGREEMENT, each PARTY agrees to keep the existence and nature of the relationship between the PARTIES as well as the terms of this AGREEMENT confidential and not to use the names of the other PARTIES in any publicity or advertisement with regard to this AGREEMENT, without the prior written consent of the other PARTY.

The confidentiality and non-use obligations created by this AGREEMENT shall be binding upon MERCK and SUPPLIER, and shall inure to the benefit of, and be enforceable by, their respective successors and assigns, and shall continue with respect to each item of INFORMATION until the earlier of (i) the occurrence of any of the conditions set forth in Section 3 with respect to such item, or (ii) ten (10) years following the expiration or termination of the SUPPLY AGREEMENT.


10.	This AGREEMENT, together with the SUPPLY AGREEMENT, embodies the entire understanding of the PARTIES with respect to the subject matter hereof and supersedes and replaces any and all prior understandings and arrangements, oral or written, relating to the INFORMATION except for any other confidentiality agreement between or among the PARTIES hereto.


11.	This AGREEMENT shall be interpreted, construed and enforced in accordance with the laws of the State of New York, without regard or reference to any of its rules or provisions governing conflict of laws.

12.

The PARTIES shall attempt to resolve amicably any dispute arising out of or relating to this AGREEMENT through good faith negotiations. In the event that said negotiations are not successful, the dispute shall be resolved through arbitration before three (3) arbitrators. Such arbitration shall take place in Chicago, Illinois and shall proceed in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”). Within fifteen (15) calendar days of either PARTY making a demand for arbitration, MERCK and SUPPLIER shall each select one (1) arbitrator. Within thirty (30) days of a demand for arbitration, a third arbitrator shall be selected by the arbitrators selected by the PARTIES. If, within the prescribed time, either PARTY shall fail to appoint its arbitrator, or the two arbitrators selected by the PARTIES fail to appoint the third arbitrator, then either PARTY may apply to the AAA for the appointment of such third arbitrator. The determination of a majority of the panel of arbitrators shall be the decision of the arbitrators and shall be binding upon the PARTIES regardless of whether one of the PARTIES fails or refuses to participate in the arbitration. The decision of the arbitrators shall be enforceable by any court of competent jurisdiction. Each PARTY shall pay for its arbitrator, with all fees and expenses of the third arbitrator being split equally between the PARTIES. All other expenses directly associated with holding an arbitration proceeding shall be split equally between the PARTIES. Either PARTY may enter any arbitration award in any court having jurisdiction

or may make application to any such court for a judicial acceptance of the award and an order of enforcement, as the case may be.


13.	Notwithstanding anything to the contrary in Section 12, each PARTY understands and agrees that any use or disclosure of INFORMATION of the other PARTY in violation of this AGREEMENT will cause such other PARTY irreparable harm leaving it without an adequate legal remedy and shall therefore entitle the other PARTY, among all other remedies, to injunctive relief from any court having jurisdiction.


15.	If any provision of this AGREEMENT is found invalid or unenforceable by a court of competent jurisdiction, the remainder of this AGREEMENT shall continue in full force and effect. The PARTIES shall negotiate in good faith to substitute a valid, legal, and enforceable provision that reflects the intent of such invalid or unenforceable provision.


16.	It is understood and agreed that no failure or delay by either PARTY in exercising any right, power, or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power, or privilege hereunder.

IN WITNESS WHEREOF, the PARTIES hereto have executed this AGREEMENT as of the 1st day of February, 2012.
