3. Supply of API 

3.1 Requirements. Subject to the terms of this Agreement, AMYLYX hereby agrees to purchase from PCA during the term of this Agreement
[***] for the research, development and commercialization of the Finished Product and PCA hereby agrees to manufacture and supply to AMYLYX, in accordance with the terms of this Agreement [***], for the development and commercialization of the
Finished Product. PCA, in addition, and without any additional; charge, fee or cost, grants to Amylyx, the right, to refer to and to use for the sole purpose of manufacturing and commercializing the Finished Product and subject to the Term of this
Agreement, the DMF relating to the API necessary for the registration of and regulatory submissions with respect to the Finished Product. Notwithstanding anything to the contrary herein contained, PCA represents and warrants that it will have and it
will continue to have during the “Launch Period”, as hereinafter defined, the ability, capacity and materials to timely manufacture and supply to AMYLYX, and agrees to provide to AMYLYX, all API ordered by AMYLYX in accordance with
the Forecast as defined and provided in Section 4 below and, in particular, without limitations, being fully applicable the procedures therewith provided under Section 4.1(a) and 4.1(b). For purposes of this Agreement, the Launch Period is
defined to mean the [***] period commencing on the Effective Date and terminating at the end of the [***] following the Effective Date. 

3.2 AMYLYX’s commitment referred under Section 3.1 shall remain in effect so long as PCA is able to fulfill AMYLYX’s
requirements for quality, quantity and timely delivery of the API, pursuant to the provisions set forth herein. Otherwise, AMYLYX shall be entitled to purchase all portions of needed API from an alternative qualified supplier, as per
Section 13.6 below without any breach or violation of this Agreement. 
 AMYLYX acknowledges that the API shall be used solely for the
purpose of developing, producing and commercializing the Finished Product in accordance with all Regulatory Activities and in compliance with Law. 

4. Forecast 
 4.1
Forecast. 
 (a) In order to enable PCA to plan the manufacturing process of the API, AMYLYX shall, within [***] days of the
Effective Date, and then subsequently within [***] days of the commencement of each calendar quarter, transmit a forecast of its requirements of API and of estimated delivery dates for the following twelve (12) month period (“rolling
twelve (12) month forecast”). Within [***] days of receiving AMYLYX’s rolling twelve (12) month forecast, and promptly at any other time that PCA identifies or reasonably anticipates a material problem that impairs its ability to
supply AMYLYX, PCA will communicate to AMYLYX any prospective problems it might have in respect to meeting forecasted quantities or estimated delivery dates and both Parties shall use their commercially reasonable efforts to remove the problems
and/or to schedule otherwise the quantities and/or the delivery dates. 












 (b) In order to assist AMYLYX to understand the impact of AMYLYX’s purchases of API on
PCA’s production and capacity, PCA and AMYLYX shall meet in-person at least [***] per year and at least [***] by conference call and more regularly as agreed to by the Parties, to evaluate AMYLYX’s planned purchases of API and PCA’s
abilities to meet AMYLYX’s planned demand. 
 4.2 Firm and indicative forecast. The first [***] of each rolling twelve
(12) month forecast shall be firm and binding for both Parties. Thus, except as provided for by Section 4.1 (a) above, PCA agrees to supply one hundred percent (100%) of the quantities ordered by AMYLYX for such a period. 

The remaining period of each rolling twelve (12) month forecast (and the related quantities) shall be indicative only and not binding on
either Party, provided that the quantities actually ordered by means of issuing purchase orders may deviate, upwards or downwards, from the most recent non-binding rolling twelve (12) month forecast to no more than [***] or less than [***]
respectively. Thus, PCA agrees to use its commercially reasonable efforts to allocate manufacturing capacity and keep stock of raw materials and API sufficient to meet the non-binding portions of the then-current rolling twelve (12) month
forecast and to accommodate any further increases in the quantity of API that AMYLYX shall request under new purchase orders. 
 AMYLYX
agrees to purchase the inventory on hand of API manufactured by PCA in order to meet the [***] quantity forecasted by AMYLYX and which has not yet been purchased by the same at termination of this Agreement as per Article 13 below. 

5. Purchase orders 

5.1 Commencing on the date on which AMYLYX receives the relevant regulatory approval to sell the Finished Product, including the API
manufactured by PCA, for commercial use in the Territory, AMYLYX will purchase the API under this Agreement by submitting written purchase orders (“P.O.”) [***] days prior to each delivery date as estimated in the then-current
rolling twelve (12) month forecast. Each P.O. shall set forth: (i) the quantity of API; and (ii) the delivery address and INCOTERMS agreed upon in advance between the Parties. 

5.2 The Parties agree that this Agreement, as amended from time to time, governs the commercial terms between them with respect to
AMYLYX’s purchase of the API from PCA. Therefore, any terms or conditions set forth in a P.O. (other than those specified to be included by the preceding paragraph) that are either inconsistent with or in addition to the terms and conditions of
this Agreement shall not be binding on either Party and shall have no force or effect. 
 5.3 PCA shall accept in writing each P.O. promptly
upon its receipt, unless the quantity specified in such P.O. is not in accordance with the terms of this Agreement, in which case PCA shall state in writing its reasons for rejecting any such P.O. as submitted by AMYLYX. In no case shall a P.O. be
considered as accepted in the absence of a written confirmation from PCA as above. Any terms and conditions in PCA’s order acceptance that are either inconsistent with or in addition to the terms and conditions of this Agreement shall not be
binding on either Party and shall have no force or effect. 
 5.4 Each P.O. issued and accepted as per 4.1 above is to be deemed as binding
for both Parties, without prejudice to any other provision set forth herein or in a subsequent agreement in writing between the Parties. 

6. Delivery and acceptance 

6.1 Delivery. The delivery of the API to AMYLYX shall be carried out “CIP/EX WORKS” the ship-to location specified, pursuant
to Section 5.1 above, in the purchase orders issued by AMYLYX to PCA, as such term is defined in ICC INCOTERMS (2010). 












 The API shall be delivered in PCA’s normal packaging, as substantially reflected in its
DMF and/or in the Specifications attached hereto. 
 PCA shall use its commercially reasonable efforts to deliver the API by the estimated
delivery date. PCA shall notify AMYLYX in writing if PCA has reason to believe that the actual delivery will not occur within [***] days of the estimated delivery date. In the event that PCA cannot deliver API to AMYLYX within [***] days after the
delivery date specified in a P.O., PCA agrees that AMYLYX may, in its sole discretion, elect to cancel such portion of a P.O. relating to such API and procure the API pursuant to Section 13.6, or accept partial or complete delivery at a later
date specified by PCA. 
 6.2 Inspection and acceptance. The delivered API shall be deemed as fully accepted if AMYLYX does not
notify PCA of the API’s proved Defect within [***] days after the documented date of receipt unless the Defect is a latent Defect that could not reasonably be discovered within [***] days in which event, AMYLYX shall notify PCA within [***]
days of discovery. Thus, AMYLYX shall endeavour to promptly inspect the API upon receipt, at its own cost, pursuant to the cGMPs regarding the controls to be performed by the manufacturer of a Pharmaceutical Product over raw and incoming materials
and shall give—by the aforementioned term — written notice of any claim, setting forth the details and giving evidence of such Defect or a latent Defect as the case may be. 

6.3 Disputes. The Parties agree to consult with each other to resolve the discrepancy between each other’s determinations, if any,
about any alleged Defect. If such consultation does not resolve the discrepancy within [***] days after identification of the discrepancy, then the Parties shall nominate a mutually agreeable reputable independent laboratory to test representative
samples taken from such shipment. The results of such tests shall be binding on the Parties and the expense of such tests shall be borne by the Party against which the laboratory decided. 

6.4 Reimbursement or Replacement. Subject to the resolution of any disputes regarding the Defective API pursuant to Section 6.3,
if AMYLYX has paid for the Defective API, then PCA shall at no additional cost, using commercially reasonable efforts, promptly cause such Defective API to be replaced with API conforming to provisions under Section 8.1 or, at AMYLYX’s
option, credit AMYLYX for the amount paid for such Defective API. All Defective API shall upon the request of PCA, and at its sole cost, be returned to PCA at the address set forth herein, packed and shipped according to instructions provided by PCA
at PCA’s expense. 
 6.5 In case of Defective API, AMYLYX—if necessary—may utilize a secondary supplier selected pursuant to
Section 13.6 as reasonably necessary to fulfil its requirements. AMYLYX may only make use of such secondary supplier in the event PCA is unable to fulfil any of its obligations as provided under Section 13.4 of this Agreement. 

6.6 In case the Defect would be due to improper handling or storage conditions subsequent to delivery of the API, no liability will occur to
PCA. 
 7. Price and payment 

7.1 Price. AMYLYX shall pay to PCA for the delivered and accepted (which acceptance shall occur within [***] days of delivery), API the
sum set forth in Exhibit A. including all applicable taxes, fees and export duties, according to the agreed Incoterms (hereinafter, “Price”). The Parties acknowledge and agree that the Price is fair and has been negotiated in
good faith also taking into account: (i) the Research & Development and Regulatory Activities carried out and to be carried out by PCA; (ii) the related costs incurred by PCA and those that PCA shall bear in the performance of
this Agreement with reference to the API; (iii) the expected date of Commercial Launch as represented by AMYLYX to PCA and the consequent volumes of API to be supplied by PCA. 












 7.2 The Price shall remain valid and in effect for [***] years as of the Commercial Launch
of the Finished Product. After such [***] years period, the Price shall automatically further apply for an additional period of [***] years (hereinafter “Additional Period”), unless the Parties mutually agree upon a new price
pursuant to the following Section 7.3. 
 7.3 In any event, upon completion of the Additional Period, if applicable, the Parties shall
mutually agree to decrease, maintain or increase the Price with good faith negotiations to start [***] months prior to the above-mentioned term. The new Price agreed shall remain valid and in effect for the term agreed between the Parties or, in the
absence of any such agreement, for [***] and will be indicated in Exhibit “A”, by means of a new Exhibit “A”, that will be attached to this Agreement. 

7.4 In the event the Parties do not reach an agreement within [***] months from the commencing of the negotiations period referred to in
Section 7.3, either Party shall have the right to terminate this Agreement by means of [***] months prior written notice to the other Party, it being understood that during such notice period the last Price agreed to by and between the Parties
shall apply and be in effect. 
 7.5 Invoicing and payment. PCA shall submit the invoice to AMYLYX upon shipment of the API and the
full invoiced amount shall be paid by AMYLYX within net [***] days after the receipt of the invoice? All payments hereunder shall be payable in USD. 

8. Quality and recall of the API 

8.1 Quality. PCA warrants that the API will be of standard quality and will be manufactured in compliance with Law and cGMPs, as per
the Specifications and the DMF. API delivered shall have a minimum retest date of not less than [***] years). 
 Quality of the API shall be
according to the mutually agreed Specifications, as well as any official standards in the Territory applicable at the Effective Date, as detailed and confirmed by the DMF. Therefore, should new, more restrictive specification(s) become effective
through new compendial monographs during the validity of this Agreement, the Parties will mutually evaluate in good faith the impact of the same on the performance of the Agreement. 

8.2 Certificate of Analysis. When each Batch is delivered API shall be accompanied by a Certificate of Analysis stating the compliance
of the API as per above. AMYLYX acknowledges, however, that it shall not be entitled to rely on the Certificate of Analysis or any such other certificate without the necessity for performing additional tests. 

8.3 Recall. Except as herein noted, PCA shall not be responsible for the costs of any recall of the Finished Product ordered by a
Competent Regulatory Authority or any other government agency or tribunal. However, if AMYLYX proves to PCA’s reasonable satisfaction, or a Competent Regulatory Authority or any other government agency or tribunal determines that the need for
the recall arose, in whole or in part, from a demonstrated latent Defect in the API not detectable by AMYLYX during the inspections to be performed by the manufacturer of a Pharmaceutical Product over the incoming active ingredients and materials
pursuant to Laws and cGMPs and pursuant to provisions under Section 6.2, AMYLYX shall notify PCA in writing within [***] days after the relevant Defect has come to AMYLYX’s notice and not more than [***] after the receipt of the Finished
Product. If the Parties disagree as to whether such recall arose, in whole or in part, from a demonstrated Defect in the API, the matter will be submitted 












 
to a mutually agreeable reputable independent laboratory for analysis to determine whether the API conformed or did not conform to the Specifications and/or requirements of Section 8.1. The
test results obtained from such laboratory shall be final and binding upon both Parties. The fees and expenses of such testing shall be borne by the Party ultimately determined to have incorrectly judged whether the API met the said requirements. In
the event that the API is deemed defective, PCA shall reimburse AMYLYX for all or a portion (in accordance with the following Section 8.4) of the reasonable and documented costs incurred in order to proceed such recall activities, or otherwise
to comply with the order of the Competent Regulatory Authority or any other government agency or tribunal. 
 8.4 The Parties agree that the
portion of the recall costs to be reimbursed by PCA under Section 8.3 shall be proportional to the relative role of such demonstrated defect in the API in causing the recall and the costs of recall activities.. 

8.5 Regulatory Registration. In so far as is necessary to allow for the production of the API and its importation and sale into the
Territory, PCA will register its manufacturing facilities and the API with the FDA and any appropriate Competent Regulatory Authority, maintain at its sole cost said registrations during the term of this Agreement, allow inspections of such
facilities by the FDA and foreign governmental authorities, maintain and make available to the FDA and other governmental authorities records, files, and any other documents relating to the manufacture, storage, shipping and quality of the API. PCA
further agrees to work with AMYLYX to enhance the DMF as reasonably suggested by AMYLYX, or by the FDA or other Competent Regulatory Authority, including, without limitation, providing AMYLYX access to PCA personnel responsible for production,
testing and validation and any related documentation, information or materials, so as to enable AMYLYX to obtain timely approval from the FDA or other Competent Regulatory Authority for the utilization of the API in the manufacture, distribution and
sale of the Finished Product formulated using API manufactured by PCA. PCA further grants to AMYLYX and its Affiliates the right to refer to and to use for the sole purpose of manufacturing and commercializing the Finished Product and subject to the
Term of this Agreement, the DMF relating to the API necessary for the registration of and regulatory submissions with respect to the Finished Product. PCA represents and warrants that it shall, at all times, maintain and keep current the DMF and
that it shall fully cooperate and timely respond to any inquiry, comment or deficiency notification from the FDA or any other Regulatory Authority as to the DMF. 

9. Records, audit and information 

9.1 Records. PCA will keep complete and accurate records regarding the manufacture and the supply of the API, as required by Law, and
agrees to give information regarding such records to AMYLYX, provided that the transmission of such information or records is permitted by applicable Law and is required by AMYLYX in connection with any FDA inspection or in order to obtain or
maintain the approvals for the Finished Product from Competent Regulatory Authorities. PCA will provide AMYLYX full access to the open part of the DMF for the API. 

9.2 Audit. Upon receipt of [***] days prior written notice from AMYLYX, PCA shall allow inspection of those areas of the facilities
during normal business hours where the API is manufactured for AMYLYX or Affiliates. Upon receipt of [***] days written notice from AMYLYX, PCA shall allow inspection of any records regarding the manufacture and the supply of the API (including
batch manufacturing records); provided, that, at a minimum, AMYLYX shall be given access generally to the types of documents that the FDA would customarily require for an FDA inspection. 

9.3 Information. AMYLYX may request at any time, PCA to transmit to AMYLYX the reference number of the DMF as well as the
“Applicant Part” of any DMF, describing the process employed by PCA for manufacture of API as envisaged in this Agreement to AMYLYX. 












 Each Party shall notify the other of any Competent Regulatory Authority’s notices of
violation or deficiency letters relating to the API and/or the Finished Product, also delivering to the other Party data, information and redacted correspondence received by it from the Competent Regulatory Authority with respect to the API (or
Finished Product) and cooperating at its own expense to the reasonable extent asked by the other Party in its response to the Competent Regulatory Authority. 

10. Changes of Specifications, plant of manufacture and/or DMF 

10.1 By PCA. In case PCA decides and/or is requested by Competent Regulatory Authority to change the Specifications, process or plant
of manufacture, and/or the DMF, there, in either case, it shall first give written notice to AMYLYX, detailing the proposed process changes and obtain prior written approval to make such changes, that cannot be unreasonably denied. If AMYLYX
demonstrates within a reasonable period of time after receiving PCA’s notice-that the change(s) proposed by PCA may disrupt: (i) the quality, quantity, timeliness or reliability of supply of the API, or (ii) AMYLYX’S ability to
use the API in the manner used by AMYLYX prior to any such change(s), or (iii) the regulatory approval in any jurisdiction of Finished Product being marketed and sold by AMYLYX, then AMYLYX shall promptly inform PCA of its determination, and
the Parties shall have an obligation to work in good faith to resolve AMYLYX’s concerns. 
 Upon the approval of such changes by
AMYLYX, AMYLYX shall exercise commercially reasonable efforts to promptly obtain the relevant approvals of Finished Product from the concerned Competent Regulatory Authority with the modified process of the API, if so required by Law, and shall
cooperate in good faith with PCA in order to plan the implementation of the process change. 
 Until the time AMYLYX obtains the approval as
above, or if AMYLYX does not approve the changes proposed by PCA, provided such non approval is based on reasonable grounds, PCA shall continue to manufacture and supply the API as per the last-approved process. 

10.2 By AMYLYX. In case AMYLYX requires PCA to change the Specifications and/or the DMF or desires that PCA consider changing the
process of manufacture, PCA—also based on AMYLYX’s detailed report regarding the implementation method of such changes and the purposes of the required changes—shall verify the feasibility of the required changes, based on the Law and
on its capacity to adapt the manufacturing process already carried out, and shall notify AMYLYX as soon as possible of the result of such analysis. 

PCA will use its commercially reasonable efforts to accommodate such changes, providing AMYLYX with an estimation of the relevant costs and
both parties shall cooperate in order to draw up an amendment to the Specifications, if required by such changes. PCA shall carefully consider any recommendation made by AMYLYX with reference to the implementation of the proposed changes. Once PCA
and AMYLYX have mutually agreed on an amendment to the Specifications, on the relative timeframes and general principles of proposed changes implementation and the costs therefore, PCA shall implement such changes and AMYLYX shall reimburse PCA for
its costs in doing so. 
 10.3 By Law. In the event that Law applicable to PCA’ manufacturing activities requires PCA to change
the Specifications or process of manufacture, and/or the DMF, PCA shall carry out all the changes pursuant to such Law and AMYLYX, where required, shall assist PCA. Should the changes above involve relevant additional costs or investment in
manufacturing the API, the Parties shall negotiate in good faith appropriate compensation of PCA for such additional costs (which may either take the form of a cost reimbursement or a proportional increase of the supply price of the API). 












 10.4 It remains understood and agreed, that, in any case of change as per articles above,
PCA will continue carrying out all of its activities in compliance with mandatory laws applicable to its activities under this Agreement. 

11. Warranty 

11.1 Warranty by Parties. Each Party declares and warrants that it has all necessary legal and statutory approvals to conduct its
business and to enter into the obligations imposed upon it by this Agreement, including any Exhibits attached hereto. 
 11.2
Warranty by PCA. PCA warrants that the delivered API shall: (i) adhere to description and requisites set forth in this Agreement and in the DMF; (ii) be manufactured strictly in compliance with Law, this Agreement and cGMPs;
(iii) meet all Specifications; (iv) be free of security interests and other similar encumbrance; and (v) not to be adulterated or misbranded. 

PCA declares that, to the best of its knowledge, neither the API nor the manufacturing process adopted in manufacturing the API infringes any

regulations or standards of any other relevant jurisdiction. Upon written request of Amylyx, PCA shall, within [***] business days, provide written confirmation that it has complied with the foregoing obligation. PCA agrees to immediately disclose

services in any capacity in connection with this Agreement. 
 Except as expressly set forth in this Agreement, PCA makes no other
warranties, express or implied, with respect to the API; thus all other warranties, express or implied, including without limitation, the implied warranties of merchantability and fitness for a particular purpose are hereby disclaimed by PCA. 

11.3 Warranty by AMYLYX. AMYLYX warrants that it shall pay for the delivered and accepted API, which acceptance shall occur within [***]
days of delivery. AMYLYX warrants that, to the extent AMYLYX determines in its sole discretion to develop or commercialize Finished Product in any given jurisdiction of the Territory, AMYLYX shall use its commercially reasonable efforts, at its sole
expense, to obtain and maintain any and all approval, registration or like with regard to producing, marketing, selling, labelling or otherwise promoting the Finished Product. Except as otherwise expressly provided by this Agreement, AMYLYX shall be
responsible for compliance with Law applicable to manufacturing, marketing, and commercializing the Finished Product. 
 Except as expressly
set forth in this Agreement, AMYLYX makes no other warranties, express or implied, with respect to the Finished Product or otherwise; thus all other warranties, express or implied, including without limitation, the implied warranties of
merchantability and fitness for a particular purpose are hereby disclaimed by AMYLYX. 












 The warranties set forth in Sections 11.1, 11.2 and 11.3 shall be deemed given as of the
Effective Date and shall be deemed given as of the date of each delivery of API hereunder, with respect to the API so delivered. 
 11.4

Territory, including the commercialization of the Finished Product, PCA hereby grants AMYLYX a worldwide and free license to such Intellectual Property relating to the API. Notwithstanding anything to the contrary herein contained, it is agreed and
understood that if AMYLYX or any Affiliate or distributor has in its inventory has or under a signed purchase order, any Finished Product following the expiration or termination of this Agreement, then AMYLYX or any Affiliate or distributor shall be

11.5 The Parties acknowledge and agree that the Intellectual Property relating to the Finished Product exclusively belongs to AMYLYX. 

11.6 Trademarks. Without prejudice to Section 11.4, each Party undertakes not to use the other Party’s name, trade mark or

 In any case, neither Party shall make any use of the other Party’s name, trade mark or corporate name in a way that might
result—directly or indirectly—in harm to the other Party’s business or products.

Insurance 
 12.1 Indemnification.

expenses occurred as a result of either (i) the use made by AMYLYX of the API in combination with other product(s) or excipients in pharmaceutical formulation to the extent such claims, demands, actions, suits, causes of action, damages or
expenses arise not out of the unmodified API, but instead as a result of the combination, other product(s) or excipients or formulation, or (ii) modification of the API made by AMYLYX without prior written consent of PCA, or
(iii) AMYLYX’s gross negligence, willful misconduct, or breach of its warranties or obligations contained herein; or (iv) improper handling or storage of the API by AMYLYX and/or carriage in the event the API is delivered EX WORKS.

13.2 Early Termination for Insolvency. This Agreement (or the relevant Purchase Orders already issued) may be forthwith terminated by
either Party immediately upon written notice by one Party to the other, if the other Party is unable to pay its debts, becomes insolvent, files or has filed against it a petition of bankruptcy, makes an assignment for the benefit of creditors or

 13.3 Early termination for non-compliance with Commercial Launch Plan. The Parties agree
that if any of the following occurs: 
 (i) in case of lack of filing by AMYLYX of the regulatory documentation relating to the NDA and the

obligations hereunder, by giving written notice of its intent to terminate and stating the grounds therefore. The Party receiving such written notice, shall have [***] days from the receipt thereof to cure the failure or breach. If such failure or
breach has not been timely cured, the Party that delivered such notice shall have the right to immediately terminate this Agreement. In no event, however, shall such notice of intention to terminate be deemed to waive any rights to damages or any
other remedy which the Party giving notice of breach may have as a consequence of such failure or breach. 
 13.5 Effect of
termination. Termination of this Agreement, for whatever reason, shall not affect this provision and the obligations of either Party under Sections 8, 9, 11, 12, 14 and 16, all of which shall remain and continue in full force and effect.

Regulatory Authority, competent judicial authorities or other competent authorities, or serves purposes that are closely related to the performance of this Agreement, and then only upon the giving of advance notice to the other Party, where it is

employees and/or collaborators comply with the provisions made herein.

whatsoever apart from its own employees, representatives, and professional consultants requiring this information, on a strictly “need to know basis”, provided that they are directly involved in the project. In such a case the Party
disclosing Confidential Information shall have the responsibility to ensure that any entity to whom Confidential Information is communicated complies with the conditions laid down herein exactly as if that entity were a party to this Agreement.

approval of the other Party. Either Party may, however, without any such written approval, assign and transfer this Agreement to a third party in connection with the transfer or sale of all or substantially all of its securities or assets related to
the division or the subject business, including for the sake of clarity the sale of or the transfer of title rights into the business of the API or Finished Product, or in the event of its sale, merger or consolidation or change in control. This

forth in this Agreement which are directly due to the Force Majeure event.
