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



| | A. | Services

when the parties desire to begin the Services set forth therein. If there is a conflict between the terms contained in any Project Proposal and this Contract, the terms of this Contract shall control, unless specifically agreed upon to the contrary
in the Project Proposal. No obligation shall be incurred by either party unless a Project Proposal has been executed by the authorized agents of both parties.

(b) Patheon will conduct the Services in accordance with the Project Proposal(s), which may be amended from time to time upon the mutual

agrees not to intentionally change or deviate in any material manner from the Project Proposals without Clients prior written approval.

(c) The parties acknowledge that while performing the Services additional costs may be incurred by Patheon as a result of unforeseen
procedural changes which do not amount to or require a change in the Project Proposals, but which are deemed necessary by Patheon to successfully perform the Services. If this occurs, Patheon shall obtain the Clients prior written agreement as
to the necessity and additional cost thereof.

(d) Patheon will comply with all applicable Laws (as defined below) while performing the
Services. If applicable, Patheon will perform the Services in compliance with the current good laboratory practices of the appropriate Authority (as defined below).

warranty or covenant contained herein, except to the extent that the losses, damages, costs, claims, demands, judgments, and liability are due to the negligence or wrongful act(s) of Client, its officers, employees, agents, or affiliates.



| | D. | Client.
| | -- | -------

Client agrees to defend, indemnify, and hold Patheon, its officers,
employees, and agents harmless against any and all losses, damages, costs, claims, demands, judgments and liability to, from and in favour of third parties (other than affiliates) resulting from, or relating to (i) any claim of infringement or

| | E. | Indemnification Procedure
| | -- | -------------------------

If a claim occurs for which a party has an indemnification
obligation under Section 6(C) or 6(D) above, the indemnified party (the Indemnitee) will: (a) promptly notify the indemnifying party (the Indemnitor) in writing of the claim; (b) use commercially
reasonable efforts to mitigate the effects of the claim; (c) reasonably cooperate with the Indemnitor in the defense of the claim; and (d) permit the Indemnitor to control the defense and settlement of the claim, with counsel reasonably
satisfactory to the Indemnitee, all at the Indemnitors cost and expense. If the Indemnitor assumes the defense of the claim, the Indemnitee may participate in such defense with the Indemnitees own counsel who will be retained, at the
Indemnitees sole cost and expense; provided, however, that neither the Indemnitor nor the Indemnitee will consent to the entry of any judgment or enter into any settlement with respect to the claim without the prior written consent of the
other party, which consent will not be unreasonably withheld or delayed. If the Indemnitee withholds consent in respect of a judgment or settlement involving only the payment of

money by the Indemnitor and which would not involve any stipulation or admission of liability or result in the Indemnitee becoming subject to injunctive relief or other relief, the Indemnitor
will have the right, upon written notice to the Indemnitee within five days after receipt of the Indemnitees written denial of consent, to pay to the Indemnitee, or to a trust for its or the applicable third partys benefit, such amount
established by such judgment or settlement in addition to all interest, costs or other charges relating thereto, together with all attorneys fees and expenses incurred to such date for which the Indemnitor is obligated under this Contract, if
any, at which time the Indemnitors rights and obligations with respect to such claim will cease. The Indemnitor will not be liable for any settlement or other disposition of a claim by the Indemnitee which is reached without the written
consent of the Indemnitor.



| | F. | No Warranty
| | -- | -----------

NEITHER PARTY MAKES ANY WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
BY FACT OR LAW, OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS CONTRACT. PATHEON MAKES NO WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE OR WARRANTY OF MERCHANTABILITY IN RESPECT OF THE CLIENTS PRODUCT.



|7. | Regulatory Filings:

| | (a) | Client shall have the sole responsibility for filing of all documents with the applicable regulatory authority (such as the United States Food and Drug Administration (FDA), the Health Products and
Food Branch of Health Canada or the European Medicine Evaluation Agency) (the Regulatory Authority) and to take any other actions that may be required for the receipt of approval from the Regulatory Authority for the commercial
manufacture of the Clients Product.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | At least 21 days prior to filing any documents with the Regulatory Authority that incorporate data generated by Patheon, Client shall provide Patheon with a copy of the documents incorporating such data so as to give
Patheon the opportunity to verify the accuracy and regulatory validity of such documents as it relates to the Patheon-generated data.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | If Patheon is selected as the commercial site of manufacture of the Product which is the subject of the Services under this Contract, then at least 21 days prior to filing with the Regulatory Authority any documentation
which is or is equivalent to the FDAs Chemistry and Manufacturing Controls (CMC) portion of the New Drug Application or of the Abbreviated New Drug Application, as the case may be, Client shall provide Patheon with a copy of
the CMC portion as well as all supporting documents which have been relied upon to prepare the CMC portion. Such disclosure shall permit Patheon to verify that the CMC portion accurately describes the Services that Patheon has performed and the
manufacturing processes that Patheon will perform pursuant to this Contract.

entity.



| | C. | Survival

parties obligations of confidentiality for the term of this Contract and for 5 years thereafter.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | F. | Other Terms
| | -- | -----------

No terms, provisions or conditions of any purchase order or other business
form or written authorization used by Client or Patheon will have any effect on the rights, duties or obligations of the parties, or otherwise modify, this Contract, regardless of any failure of Client or Patheon to object to such terms, provisions,
or conditions unless such document specifically refers to this Contract and is signed by both parties.
