| | --- | -------------------------------------------------------------------------------------------------------------------------------



|6. | Purchase Orders.
|-- | ----------------



| | (a) | The purchase and sale of API under this Agreement will be implemented by Customers issuance of individual purchase orders to ACIC or to Manufacturer for specific quantities of
API. Purchase orders will be placed at least [ * ] days before the desired delivery date and will specify the quantity of API ordered and the requested delivery date. Customer may, in its sole discretion, purchase up to [ * ] percent
([ * ]%) of the API quantities in the first Calendar Quarter of each Forecast for API. Each such purchase order issued by Customer (and as adjusted from time to time as set forth above) constitutes the binding obligation of Manufacturer to
Manufacture, sell and deliver to Customer the quantity of API by the delivery date specified in such purchase order, and the binding obligation of Customer to purchase the quantity of API specified therein; provided, that if Customer requests any
increase in the quantity of any API in a purchase order in excess of [ * ] percent ([ * ]%) of such quantities, then Manufacturer shall use commercially reasonable efforts to supply the additional API quantity at the Purchase Price.
Each purchase order or any acknowledgment thereof, whether printed, stamped, typed, or written shall be governed by the terms of this Agreement and none of the provisions of such purchase order or acknowledgment shall be applicable except those
specifying API and quantity ordered, delivery dates, special shipping instructions and invoice information. In the event of a conflict between the terms and conditions of this Agreement and any purchase order, the terms and conditions of this
Agreement will prevail.

|10. | Regulatory Matters. Customer is responsible for filing and obtaining any Marketing Authorization that is required for the marketing and sale of a Finished Product containing
or comprised of API supplied by Manufacturer; however, Manufacturer will fully cooperate with Customer in such activities. Each Party will notify the other party promptly upon becoming aware of any (a) defective, adulterated or misbranded API
or of any information which may suggest that any API is or may be defective, adulterated or misbranded, and (b) API which fails to meet the Specifications, the requirements of the applicable Marketing Authorization, Applicable Law or cGMP.
Manufacturer will promptly investigate and provide Customer with all reasonable assistance requested by it in connection with adverse experiences and customer complaints relating to API. Manufacturer agrees to notify Customer promptly of any
inspections by the FDA or any other Regulatory Authority which pertain to the API, or the results of which pertain to any other product that have implications to the overall quality systems of the Manufacturer thereby affecting, or potentially
affecting, overall manufacturing activity of the Manufacturer or the ability to supply the API to the Customer. Manufacturer will allow, and will provide Customer with any required authorization to allow, the FDA (or other Regulatory Authority) or
Customers Quality Personnel (QA/QC) to inspect, audit and review the facilities at which the API is Manufactured and all procedures, practices, books, records, and documents to the extent requested by the FDA (or such other Regulatory
Authority) or Customer Quality Personnel. Manufacturer will retain originals of all batch documentation, any and all other records or documentation generated by it in connection with the processing and testing of each API under the terms of this

|11. | Audits.
|--- | -------



| | (a) | Quality Related Audits By Customer. Customer will have the right, upon reasonable notice to Manufacturer and during normal business hours, to audit Manufacturers
facilities and records for the API to ensure that API is being Manufactured in compliance with the Specifications, the applicable Marketing Authorization and all Applicable Laws, including without limitation cGMP, and otherwise to ascertain
compliance with the terms of this Agreement and the Quality Assurance Agreement. During such audits, Manufacturer will make available to Customer the appropriate knowledgeable personnel of Manufacturer.

| | (b) | Financial Related Audits By Manufacturer. To monitor Customers compliance with Section 3(b) above, Customer shall cause its (and its Affiliates and their
respective designees) manufacturer(s) of Finished Products to provide on an annual basis a certified statement that sets forth (i) the total amount of Finished Product produced by such manufacturer and released by Customer (or any of its
Affiliates or respective designees) for commercial use within the Territory during that year (excluding any amount of Finished Product containing API supplied by a Second Source Supplier as a result of a Force Majeure Event under Section 26
hereof or as a result of Manufacturers inability to supply under Section 8 hereof); (ii) what amount of such Finished Product contained API supplied by Manufacturer hereunder and (iii) what amount of Finished Product contained
API supplied by a Second Source Supplier (but again excluding any amount of Finished Product containing API supplied by a Second Source Supplier as a result of a Force Majeure Event under Section 26 hereof or as a result of Manufacturers
inability to supply under Section 8 hereof). In the event that after totaling the appropriate amounts shown in the statements from all the Second Source Suppliers, the total amount of Finished Product containing API supplied by Manufacturer is
less than [ * ] percent ([ * ]%) of the total Finished Products produced and released by or on behalf of Customer (or any of its Affiliates) for commercial use within the Territory for that year, Customer shall pay to Manufacturer an
amount equal to [ * ] the total [ * ] such year and the total [ * ] was the full [ * ]. Notwithstanding anything to the contrary contained in this Agreement, such payment by Customer to Manufacturer shall constitute
Manufacturers and ACICs sole and exclusive remedy for Customers non-compliance with Section 3(b) above.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Financial Related Audits By Customer. For purposes of verifying the appropriateness of any adjustments to the Purchase Price under Section 5 hereunder,
Customer shall have the right to request, on thirty (30) days prior written notice to Manufacturer or ACIC, that a nationally recognized, independent accounting firm engaged by Customer and that Customer and Manufacturer mutually agree upon
perform an audit or interim review of Manufacturers books and records as they relate to the direct costs associated with the production and supply of API by Manufacturer to Customer hereunder. The accounting firm shall be provided access to
such books and records at Manufacturers or ACICs facility(ies) where such books and records are normally kept. Upon completion of the audit, the accounting firm shall provide the Parties a written report disclosing whether the Purchase
Price adjustments are correct or incorrect and the specific details and supporting analysis for any discrepancies. In the event any discrepancies are reported, Manufacturer shall reimburse Customer for the expense of such audit and promptly refund
to Customer any and all amounts

| | overpaid by Customer due to the inappropriate Purchase Price increase by Manufacturer. In the event no discrepancies are reported, Customer shall bear the
expense of such audit. Such audit hereunder shall not be performed more frequently than once per calendar year nor more frequently than once with respect to records covering any specific period of time. All information provided by Manufacturer
hereunder referred to shall be used only for the purpose of verifying the Purchase Price adjustment under Section 5 hereunder and shall be treated as Manufacturers Information subject to the confidentiality obligations set forth in this
Agreement. In the event Manufacturer in good faith disputes the findings of the audit, the Parties agree to submit such dispute to arbitration in accordance with Section 32 hereof.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12. | Recalls.In the event that (i) any government authority issues a request, directive or order that the API or Finished Product be recalled or (ii) a court of
competent jurisdiction orders such a recall, or (iii) Customer determines after consultation with Manufacturer that the API or Finished Product should be recalled, the Parties shall take all appropriate corrective actions. In the event that
such recall results from the failure of the API to meet the Specifications and such failure could not reasonably be detected by Customer during the Inspection Period, Manufacturer shall be responsible for all expenses of recall. In all other cases,
Customer shall be responsible for the expense of recall. For purposes of this Agreement, the expenses of recall shall include without limitation the expense of notification and destruction or return of the recalled API or Finished Product.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|13. | Changes in Specification.If the Specifications must be modified by requirement of a Regulatory Authority, or a process change would be required under the CMC, or other
applicable governmental application, Manufacturer shall make such change in a prompt and timely manner. If such modification results in the requirement to reprocess and/or retest previously manufactured and otherwise acceptable API, any additional
costs incurred by Manufacturer in such reprocessing and/or retesting shall be paid by Customer upon submission by Manufacturer of documentation and justification of such costs. Any process changes or Specification modifications pursuant to this
Section 13 shall occur pursuant to change control procedures agreed upon by Manufacturer and Customer.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|14. | Term. This Agreement shall come into effect on the Effective Date and, unless terminated earlier in accordance with this Agreement, shall remain in full
force and effect until the longer of (i) ten (10) years from the Effective Date and (ii) seven (7) years following the date of approval of the Finished Product in the first market in the Territory to be filed by Customer (the
Initial Term), subject to renewal for consecutive one (1) year terms (each a Renewal Term) upon written agreement of all the Parties, which agreement shall be reached no later than [ * ] days prior
to the expiration date of the Initial Term or any Renewal Term, as applicable. In the event that Manufacturer decides not to renew such Agreement or in the event this Agreement is terminated earlier by Customer in accordance with
Section 15(b)(i) or Section 15(b)(ii) hereof, upon Customers request, Manufacturer shall provide reasonable assistance to Customer in

| | transferring the Manufacturing process to another supplier designated by Customer by providing reasonable technical assistance and documentation relating to
the manufacture, testing and supply of the API. Such reasonable assistance shall encompass provision of documentation in the most current version which is not yet in possession of Customer at the time, and technical assistance by Manufacturer to an
extent to be agreed upon by the Parties in good faith. Upon expiration of this Agreement or in the event of early termination pursuant to Section 15 below, Sections 1, 2, 10, 16-25, 27-32, 33 (except with respect to licenses granted

| | (ii) | the other Party makes an arrangement with its creditors for the assignment of all or a substantial portion of its assets or goes into bankruptcy, receivership or liquidation, or if
a receiver or a receiver and manager is appointed in respect of the whole or a major part of the property or business of the Party in default; or
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | it is not commercially reasonable for Customer to sell, or to purchase as the case may, the API (or a Finished Product containing or comprised of such API) in the Territory; or
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | the manufacture, use, sale or importation of such APIs in the Territory is found by a court of competent jurisdiction in a final, unappealable decision to infringe the patent or
other intellectual property rights of a Third Party from whom Customer or Manufacturer is unable to obtain a license to manufacture, use, sell, or import such API.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Such termination under Section 15(b) shall be effective [ * ] days after the date specified in the written notice subject only to resolution
under the arbitration provisions of this Agreement.

|22. | No Waiver of Rights. The failure or delay of a Party hereto to exercise any right, power, or privilege under this Agreement shall not be presumed to operate as a waiver of
such right, power, or privilege of such Party thereafter to enforce each and every such right, power, or privilege on any succeeding occasion or breach of this Agreement. A single or partial exercise of any right, power or privilege will not be
presumed to preclude any subsequent or further exercise, of that right, power or privilege, or the exercise of any other right, power or privilege.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|23. | Enurement. This Agreement shall enure to the benefit of and be binding upon the Parties hereto and their respective heirs, executors, administrators, successors, and
permitted assigns.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|24. | Assignment. This Agreement and any rights arising hereunder may not be assigned by either Party without the prior written consent of the other Party(ies) (each, a
Consenting Party), and which consent may not be unreasonably or arbitrarily withheld. In the event of an assignment, such assignment shall only be effective upon approval in written form by the Consenting Party(ies).
Notwithstanding anything to the contrary contained herein, this Agreement may be assigned by Customer without the consent of the other Parties to an acquiring person or entity upon the acquisition, merger, consolidation of Customer, or of the assets
or substantially all the assets by such person or entity, relating to Customers performance hereunder. Any permitted assignee shall assume all obligations of its assignor under this Agreement. No assignment shall relieve any party of

guarantee the full performance by the assignee of such obligations.

|25. | Modification. This Agreement may only be supplemented, amended, or modified by the mutual agreement of both Parties. No supplement, amendment or modification of this
Agreement shall be binding on the Parties unless it is in writing and has been executed by the duly authorized representatives of each Party.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|26. | Force Majeure. Any delay in the performance of any of the duties or obligations of any Party (except the payment of money due hereunder) caused by an event outside the
affected Partys reasonable control and without the fault or negligence of the Party so affected (Force Majeure Event) shall not be considered a breach of this Agreement, and unless provided to the contrary herein, the time
required for performance shall be extended for a period equal to the period of such delay. Such Force Majeure Events shall include without limitation, acts of God; acts of the public enemy; insurrections; riots; injunctions; embargoes; labor
disputes, including strikes, lockouts, job actions, or boycotts; fires; explosions; floods; earthquakes; Third Party delays in the delivery of raw materials, or other unforeseeable causes beyond the reasonable control and without the fault or
negligence of the Party so affected. The Party so affected shall give prompt notice to the other Party of such cause, and shall take whatever reasonable steps are necessary to relieve the effect of such cause as rapidly as reasonably possible. For
purposes of clarity, in the event a Force Majeure Event is preventing Manufacturer from manufacturing and supplying API to Customer, Customer shall have the right to purchase its requirements of API from any Second Source Supplier and such amounts
of API purchased under this Section 26 during a given year shall not be factored into the calculation of Annual Commercial API Requirement for such year.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|27. | Severability. In the event that any of term or the provision of this Agreement shall be held invalid or unenforceable, the remaining terms hereof shall not be affected, but
shall be valid and enforced to the fullest extent permitted by law; and if any term or provision of this Agreement shall be deemed by a court to be unenforceable because such provision is too broad in scope, such provision shall be construed to be
limited in scope to the extent such court shall deem necessary to make it enforceable.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|28. | Relationship of the Parties. This Agreement does not create nor shall it be deemed to create the relationship of partners or joint-venturers between the parties. Neither
Party has the authority, without the prior written consent of the other Party, to create any obligation or responsibility on the part of the other Party or otherwise legally bind or obligate the other Party in any other manner.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|29. | Additional Documents. Each Party agrees that it will forthwith upon the request of the other Party execute and deliver all such documents, instruments and agreements and will
take all such other actions as the other Party may reasonably request from time to time in order to effectuate the provision and purposes of this Agreement.

|31. | Entire Agreement. This Agreement and the Quality Assurance Agreement incorporates the entire understanding of the Parties with respect to the subject matter herein and
cancels, revokes and supersedes any and all previous agreements, contracts, understandings, negotiations, commitments and arrangements that might have existed heretofore between the Parties regarding the subject matter herein, and all prior
agreements and understandings between the Parties and relating to the subject matter hereof are superseded by this Agreement; provided, however, that in the event that there is any conflict between the Quality Assurance Agreement and this Agreement,
this Agreement shall govern to the extent of such conflict except where such conflict is directly with respect to the appropriate procedures and the Parties respective roles in adhering to such procedures to assure the product quality and
conformance of the API (including, the testing, storage, packaging, labeling, certification, release, delivery, deviation and change notifications, communication and regulatory support therefor), in which case the Quality Assurance Agreement shall
govern to the extent of such conflict. Neither Party shall be liable or bound to the other Party in any manner by any representations, warranties, or covenants relating to such subject matter except as specifically set forth herein or in the Quality
Assurance Agreement.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|32. | Arbitration. The Parties agree that all disputes arising out of or in connection with this Agreement, including disputes related to the existence, validity,
interpretation, performance, termination or breach thereof, shall be submitted to the International Court of Arbitration of the International Chamber of Commerce and shall be finally settled under the Rules of Arbitration of the International
Chamber of Commerce. The arbitration shall be conducted in the English language. There shall be three (3) arbitrators (the Arbitration Tribunal), the first of which shall be appointed by the claimant in its notice of
arbitration, the second of which will be appointed by the respondent within thirty (30) days of the appointment of the first arbitrator, and the third of which will be jointly appointed by the Party appointed arbitrators within thirty
(30) days thereafter. If a Party fails to nominate an arbitrator, the appointment is to be made by the International Court of Arbitration. All notices required to be given in connection with the any arbitration shall be valid and sufficient if
sent in accordance with Section 20 of this Agreement. In the event of arbitration, the costs of the arbitration shall be fixed in accordance with Article 31 of the Rules of Arbitration of the International Chamber of Commerce and the final
award will have the Parties bearing the costs of arbitration in proportion to the outcome of the arbitration. If applicable under the applicable law, the Parties will submit a proposed discovery schedule to the arbitrator(s) at the pre-hearing
