	13.1	 A Party receiving Confidential Information (the “Receiving Party”) agrees to strictly keep secret any
and all Confidential Information received during the Term from or on behalf of the other Party (the “Disclosing Party”) using at least the same level of measures as it uses to protect its own Confidential Information, but in any case at
least commercially reasonable and customary efforts. Confidential Information shall include information disclosed in any form including but not limited to in writing, orally, graphically or in electronic or other form to the Receiving Party,
observed by the Receiving Party or its employees, agents, consultants, or representatives, or otherwise learned by the Receiving Party under this Agreement, which the Receiving Party knows or reasonably should know is confidential or proprietary.



  

	13.2	 Notwithstanding the foregoing, Receiving Party may disclose to any courts and/or other authorities Confidential
Information which is or will be required pursuant to applicable governmental or administrative or public law, rule, regulation or order. In such case the Party that received the Confidential Information will, to the extent legally permitted, inform
the other Party promptly in writing and cooperate with the Disclosing Party in seeking to minimize the extent of Confidential Information which is required to be disclosed to the courts and/or authorities. 



 

	13.3	 The obligation to maintain confidentiality under this Agreement does not apply to Confidential Information,
which: 


  

	 	13.3.1	 at the time of disclosure was publicly available; or 



 

	 	13.3.2	 is or becomes publicly available other than as a result of a breach of this Agreement by the Receiving Party;
or 


  

	 	13.3.3	 as the Receiving Party can establish by competent proof, was rightfully in its possession at the time of
disclosure by the Disclosing Party and had not been received from or on behalf of Disclosing Party; or 


  

	 	13.3.4	 is supplied to a Party by a Third Party which was not in breach of an obligation of confidentiality to
Disclosing Party or any other party; or 


  

	 	13.3.5	 is developed by the Receiving Party independently from and without use of the Confidential Information, as
evidenced by contemporaneous written records. 















 



 
  


	13.4	 The Receiving party will use Confidential Information only for the purposes of this Agreement and will not make
any use of the Confidential Information for its own separate benefit or the benefit of any Third Party including, without limitation, with respect to research or product development or any reverse engineering or similar testing. The Receiving Party
agrees to return or destroy promptly (and certify such destruction) on Disclosing Party’s request all written or tangible Confidential Information of the Disclosing Party, except that one copy of such Confidential Information may be kept by the
Receiving Party in its confidential files for record keeping purposes only. 


  

	13.5	 Each Party will restrict the disclosure of Confidential Information to such officers, employees, professional
advisers, finance-providers, consultants and representatives of itself and its Affiliates who have been informed of the confidential nature of the Confidential Information and who have a need to know such Confidential Information for the purpose of
this Agreement or an applicable financing or acquisition. Both Parties may disclose Confidential Information of the other Party and its Affiliates to potential and actual acquirers provided such disclosure is limited to the terms of this Agreement.
Customer also may disclose to its potential and actual: (i) acquirers and (ii) bona fide collaborators in the research, development and commercialization of the Products, the work product provided to Customer by Lonza as a consequence of
the provision of the Services. Prior to disclosure to such persons, the Receiving Party shall inform the Disclosing Party and it shall bind its and its Affiliates’ officers, employees, consultants and representatives to confidentiality and non-use obligations no less stringent than those set forth herein. The Receiving Party shall notify the Disclosing Party as promptly as practicable of any unauthorized use or disclosure of the Confidential
Information. 


  

	13.6	 The Receiving Party shall at any time be fully liable for any and all breaches of the confidentiality
obligations in this Clause 13 by any of its Affiliates or the employees, consultants, potential and actual acquirers, and representatives of itself or its Affiliates. 



 

	13.7	 Each Party hereto expressly agrees that any breach or threatened breach of the undertakings of confidentiality
provided under this Clause 13 by a Party may cause irreparable harm to the other Party and that money damages may not provide a sufficient remedy to the non-breaching Party for any breach or threatened breach.
In the event of any breach and/or threatened breach, then, in addition to all other remedies available at law or in equity, the non-breaching Party shall be entitled to seek injunctive relief and any other
relief deemed appropriate by the non-breaching Party. 


  

	14	 Term and Termination 



 

	14.1	 Term. This Agreement shall commence on the Effective Date and shall end on the fifth (5th) anniversary of the Effective Date unless terminated earlier as provided herein or extended by mutual written consent of the Parties (the “Term”). Notwithstanding the foregoing, each

commenced and performed under any purchase order(s) by Lonza prior to the termination notice date; 


  

	 	14.2.2	 by either Party if the other Party breaches a material provision of this Agreement or a Project Plan and fails
to cure such breach to the reasonable satisfaction of the non-breaching Party within [***] following written notification of such breach from the non-breaching party to
the breaching party; provided, however, that such [***] period shall be extended as agreed by the Parties if the identified breach is incapable of cure within [***] and if the breaching Party provides a plan and timeline to cure the breach, promptly
commences efforts to cure the breach and diligently prosecutes such cure [***]; 















 



 
  


	 	14.2.3	 by either Party, immediately, if the other Party becomes insolvent, is dissolved or liquidated, makes a general
assignment for the benefit of its creditors, or files or has filed against it, a petition in bankruptcy or has a receiver appointed for a substantial part of its assets; or 



 

	 	14.2.4	 by either Party pursuant to Clause 15. 



 

	14.3	 Consequences of Termination. In the event of termination hereunder, Lonza shall be compensated for
(i) Services rendered up to the date of termination, including in respect of any Product in-process; (ii) all costs incurred through the date of termination, including Raw Materials costs and Raw
Materials Fees for Raw Materials used or purchased for use in connection with the Project Plan; (iii) all unreimbursed Capital Equipment and related decommissioning charges incurred pursuant to Clause 9; (iv) all amounts due under Clause 6.4,
without proration of the final calendar year and (v) any applicable Cancellation Fees. In the case of termination by Lonza for Customer’s material breach, Cancellation Fees shall be calculated as of the date of written notice of
termination. 


  

	14.4	 Survival. The rights and obligations of each Party which by their nature survive the termination or
expiration of this Agreement shall survive the termination or expiration of this Agreement, including Clauses 5, 10-13 and 16 (to the extent relevant). 



 

	15	 Force Majeure 



 

	15.1	 If Lonza is prevented or delayed in the performance of any of its obligations under the Agreement by Force
Majeure and gives written notice thereof to Customer specifying the matters constituting Force Majeure together with such evidence as Lanza reasonably can give and specifying the period for which It Is estimated that such prevention or delay will
continue, Lonza shall be excused from the performance or the punctual performance of such obligations as the case may be from the date of such notice for so long as such cause of prevention or delay shall continue. Provided that, if such Force
Majeure persists for a period of [***] or more, Customer may terminate this Agreement by delivering written notice to Lonza. 


  

	15.2	 “Force Majeure” shall be deemed to include any reason or cause beyond Lonza’s reasonable control
affecting the performance by Lonza of its obligations under the Agreement, including, but not limited to, any cause arising from or attributable to acts of God, strike, labor troubles, restrictive governmental orders or decrees, riots, insurrection,
war, terrorist acts, or the inability of Lonza to obtain any required raw material, energy source, equipment, labor or transportation, at prices and on terms deemed by Lonza to be reasonably practicable, from Lonza’s usual sources of supply.



  

	15.3	 With regard to Lonza, any such event of Force Majeure affecting services or production at its Affiliates or
suppliers shall be regarded as an event of Force Majeure. 


  

	16	 Miscellaneous 



 

	16.1	 Severability. If any provision hereof is or becomes at any time illegal, invalid or unenforceable in any
respect, neither the legality, validity nor enforceability of the remaining provisions hereof shall in any way be affected or impaired thereby. The Parties hereto undertake to substitute any illegal, invalid or unenforceable provision by a provision
which is as far as possible commercially equivalent considering the legal interests and the Purpose. 


  

	16.2	 Amendments. Modifications and/or amendments of this Agreement must be in writing and signed by the
Parties. 















 



 
  


	16.3	 Assignment. Lonza shall be entitled to instruct one or more of its Affiliates to perform any of
Lonza’s obligations contained in this Agreement, but Lonza shall remain fully responsible in respect of those obligations. Neither Party may assign its interest under this Agreement without the prior written consent of the other Party, such
consent not to be unreasonably withheld, conditioned or delayed, provided, however that either Party may assign this Agreement to (i) any Affiliate of such Party or (ii) any third party in connection with the sale or transfer (by whatever
method) of all or substantially all of the assets of the business or Product of such Party to which this Agreement relates, whether by merger, consolidation, acquisition or other form of business combination. Any purported assignment without a
required consent shall be void. No assignment shall relieve any Party of responsibility for the performance of any obligation that accrued prior to the effective date of such assignment. Lonza shall be entitled to sell, assign and/or transfer its

regard to its conflicts of laws principles. The Parties agree to submit to the jurisdiction of the state and federal courts [***]. 


  

	16.6	 Entire Agreement. This Agreement contains the entire agreement between the Parties as to the subject
matter hereof and supersedes all prior and contemporaneous agreements with respect to the subject matter hereof. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of which together
