verifying any amounts payable under  

  
 ***Confidential Treatment Requested 








 
this Agreement. Such audits may be exercised during normal business hours upon reasonable prior written notice to Celladon. Prompt adjustments shall be made by the parties to reflect the results
of such audit. AskBio shall bear the full cost of such audit, unless such audit discloses a variance of more than 5% from the amounts actually due, in which case Celladon shall bear the full cost of such audit. 

5. CONFIDENTIALITY 

5.1 Confidentiality. Except to the extent expressly authorized by this Agreement or
otherwise agreed in writing by the parties, the parties agree that, during the term of this Agreement and for five (5) years thereafter, each party shall keep confidential and shall not publish or otherwise disclose and shall not use for any
purpose other than as expressly provided for in this Agreement any information furnished to it by the other party pursuant to this Agreement (collectively, “Confidential Information”). Each party may use Confidential
Information of the other party only to the extent required to accomplish the purposes of this Agreement. Each party will use at least the same standard of care as it uses to protect proprietary or confidential information of its own to ensure that
its employees, agents, consultants and other representatives do not disclose or make any unauthorized use of the other party’s Confidential Information. Each party will promptly notify the other upon discovery of any unauthorized use or
disclosure of the other party’s Confidential Information. 
 5.2 Exceptions.
Confidential Information of a party (the “disclosing party”) shall not include any information which the other party (the “receiving party”) can prove by competent evidence:
(a) is now, or hereafter becomes, through no act or failure to act on the part of the receiving party in breach of this Agreement, generally known or available; (b) is known by the receiving party at the time of receiving such information,
as evidenced by its previously-existing written records; (c) is hereafter furnished to the receiving party by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the
receiving party without the use of Confidential Information belonging to the disclosing party. 
 5.3
Authorized Disclosure. The receiving party may disclose Confidential Information to the extent such disclosure is reasonably necessary in filing or prosecuting patent applications, prosecuting or defending litigation or complying with applicable
governmental regulations, provided that if the receiving party is required to make any such disclosure of the Confidential Information, it will to the extent practicable give reasonable advance notice to the disclosing party of such disclosure
requirement and, except to the extent inappropriate in the case of patent applications, will cooperate with the disclosing party’s efforts to secure confidential treatment of such information required to be disclosed at the request and expense
of the disclosing party. 
 6. PATENT PROSECUTION 

AskBio shall be solely responsible for filing, prosecution, maintenance and enforcement of the Patent Rights, at AskBio’s
expense. Celladon shall be solely responsible for filing, prosecution, maintenance and enforcement of the Cross-License Patent Rights, at Celladon’s expense. 







 7. REPRESENTATIONS AND WARRANTIES 

7.1 AskBio Representations and Warranties. AskBio hereby represents and warrants to Celladon that: 

(a) AskBio has the full legal power, authority and right to grant the license under the Patent Rights that it purports
to grant hereunder and to perform its obligations under this Agreement; 
 (b) upon execution and delivery by both
parties, this Agreement will constitute a valid and binding agreement of AskBio, enforceable against AskBio in accordance with its terms; 

(c) neither AskBio nor any of its Affiliates is a party to any legal action, suit or proceeding relating to the Patent
Rights; 
 (d) the execution, delivery and performance of this Agreement do not conflict with any agreement,
instrument or understanding, oral or written, to which AskBio or any of its Affiliates is a party or by which AskBio or any of its Affiliates may be bound. During the term of this Agreement, neither AskBio nor any of its Affiliates shall enter into
any agreement, or take or fail to take any action, that would restrict AskBio’s legal right to grant to Celladon the rights and benefits contemplated under this Agreement; 

(e) pursuant to that certain license agreement between Asklepios and The University of North Carolina at Chapel Hill
(“UNC-CH”) dated as of April 22, 2003, as amended from time to time (the “UNC License Agreement”), Asklepios is the exclusive licensee of all right, title and interest in and to the
Patent Rights. Asklepios, in turn, granted an exclusive license of all right, title and interest in and to the Patent Rights for use in cardiac applications to AskBio. AskBio shall promptly notify Celladon in writing of the termination of the UNC
License Agreement; and 
 (f) pursuant to the UNC License Agreement, upon the termination of the UNC License Agreement
for any reason, this Agreement shall be assumed by UNC-CH, provided that where UNC-CH would be required, as a licensor, to assume duties that are impractical or
inconsistent with its research, educational and public service mission or that are impermissible for an agency of the State of North Carolina, UNC-CH will not be required to assume such duties or obligations,
and UNC-CH and Celladon will negotiate in good faith to amend such terms accordingly. 

7.2 Celladon Representations and Warranties. Celladon hereby represents and warrants to AskBio that: 

(a) Celladon has the full legal power, authority and right to grant the Option under the Cross-License Patent Rights
that it purports to grant hereunder and, upon exercise of such Option, to grant the license described in Section 2.3, and to perform its obligations under this Agreement; 







 (b) upon execution and delivery by both parties, this Agreement will
constitute a valid and binding agreement of Celladon, enforceable against Celladon in accordance with its terms; 

(c) neither Celladon nor any of its Affiliates is a party to any legal action, suit or proceeding relating to the
Cross-License Patent Rights; and 
 (d) the execution, delivery and performance of this Agreement do not conflict with
any agreement, instrument or understanding, oral or written, to which Celladon or any of its Affiliates is a party or by which Celladon or any of its Affiliates may be bound. During the term of this Agreement, neither Celladon nor any of its
Affiliates shall enter into any agreement, or take or fail to take any action, that would restrict Celladon’s legal right to grant to AskBio the rights and benefits contemplated under this Agreement. 

7.3 Disclaimer. THE INTELLECTUAL PROPERTY RIGHTS PROVIDED BY EACH PARTY HEREUNDER ARE PROVIDED “AS IS” AND,
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, EACH PARTY EXPRESSLY DISCLAIMS ANY AND ALL WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THE WARRANTIES OF DESIGN, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NONINFRINGEMENT OF THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES, OR ARISING FROM A COURSE OF DEALING, USAGE OR TRADE PRACTICES. 

7.4 Limitation of Liability. EXCEPT FOR AMOUNTS PAYABLE UNDER ARTICLE 3 AND LIABILITY FOR BREACH OF ARTICLE 5,
NEITHER PARTY SHALL BE ENTITLED TO RECOVER FROM THE OTHER PARTY ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT, EACH PARTY’S PERFORMANCE OR LACK OF PERFORMANCE HEREUNDER OR ANY LICENSE GRANTED
HEREUNDER; provided, however, that this Section 7.4 shall not be construed to limit either party’s indemnification obligations under Article 9. 

8. TERM; TERMINATION 

8.1 Term. The term of this Agreement shall commence as of the Effective Date and shall continue until expiration of all
royalty payment obligations under Section 3.3. Following the expiration of this Agreement, Celladon shall have a license on the same terms as set forth in Section 2.1, except that the license shall be fully-paid, royalty-free, irrevocable and perpetual. 
 8.2 Termination for Breach. A
party may terminate this Agreement prior to its expiration upon or after the breach of any material provision of this Agreement by the other party if the breaching party has not cured such breach within 30 days after written notice thereof by
the non-breaching party. 
 8.3 Termination by Celladon. Celladon may terminate this Agreement prior to its
expiration at any time, for any reason or for no reason, upon 180 days’ written notice to AskBio. 







 8.4 Effect of Termination. 

(a) Upon termination of this Agreement (i) the license granted under Section 2.1 shall terminate and be of no
further force or effect, and (ii) any sublicense granted hereunder by Celladon shall terminate and be of no further force or effect; provided, however, that AskBio shall have the right, but not the obligation, to assume any such
sublicense agreement. 
 (b) Within 30 days following the termination of this Agreement, each party shall return
to the other party, or destroy, upon the written request of the other party, any and all Confidential Information of the other party in its possession. 

(c) Expiration or termination of this Agreement shall not relieve the parties of any obligation accruing prior to such
expiration or termination. The provisions of Section 2.3 of this Agreement shall survive termination of this Agreement by AskBio pursuant to Section 8.2 for Celladon’s uncured material breach and termination of this Agreement by
Celladon pursuant to Section 8.3, but shall not survive termination of this Agreement by Celladon pursuant to Section 8.2 for AskBio’s uncured material breach or expiration of this Agreement. The provisions of Sections 4.4, 7.3,
7.4 and 8.4 and Articles 1, 5, 6, 9, 10 and 11 shall survive any termination or expiration of this Agreement. 
 9. INDEMNIFICATION

 9.1 Indemnification by Celladon. Celladon hereby agrees to save, defend, indemnify and hold harmless AskBio,
its Affiliates and their respective officers, directors, employees, consultants and agents (the “AskBio Indemnitees”) from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal
expense and attorneys’ fees (“Losses”), to which AskBio may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise directly or indirectly out of
(a) the gross negligence or willful misconduct of Celladon, (b) the breach by Celladon of any warranty, representation, covenant or agreement made by Celladon in this Agreement, or (c) the development, manufacture, use, handling,
storage, sale or other disposition of any Product by Celladon, its Affiliates or sublicensees; in each case except to the extent such Losses result from the gross negligence or willful misconduct of any AskBio Indemnitee or the breach by AskBio of
any warranty, representation, covenant or agreement made by AskBio in this Agreement. 
 9.2 Control of Defense. In
the event AskBio seeks indemnification under Section 9.1, it shall inform Celladon of a claim as soon as reasonably practicable after it receives notice of the claim, shall permit Celladon to assume direction and control of the defense of the
claim (including the right to settle the claim solely for monetary consideration), and shall cooperate as requested (at the expense of Celladon) in the defense of the claim. 

10. DISPUTE RESOLUTION 

10.1 Dispute Resolution. Any dispute arising under or relating to the parties rights and obligations under this
Agreement will be referred to the Chief Executive Officers of Celladon and AskBio for resolution. In the event such officers are unable to resolve such dispute  







 
within 30 days or such dispute being referred to them, then, upon the written request of either party to the other party, the dispute shall be subject to arbitration, as provided in
Section 10.2. 
 10.2 Arbitration. 

(a) Claims. Subject to Section 10.3 below, any claim, dispute, or controversy of whatever nature arising out of or
relating to this Agreement that is not resolved under Section 10.1 within the applicable 30-day time period, including, without limitation, any action or claim based on tort, contract, or statute, or
concerning the interpretation, effect, termination, validity, performance and/or breach of this Agreement (“Claim”), shall be resolved by final and binding arbitration before a panel of three experts with relevant industry
experience (the “Arbitrators”). One Arbitrator shall be chosen by Celladon and one Arbitrator shall be chosen by AskBio within 15 days from the notice of initiation of arbitration. The third Arbitrator shall be chosen by
mutual agreement of the Arbitrator chosen by Celladon and the Arbitrator chosen by AskBio within 15 days of the date that the last of such Arbitrators were appointed. The arbitration shall be administered by the American Arbitration Association (the
“Administrator”) in accordance with its then existing arbitration rules or procedures regarding commercial or business disputes. The arbitration shall be held in Raleigh, North Carolina. 

(b) Arbitrators’ Award. The Arbitrators shall, within 15 days after the conclusion of the arbitration
hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The decision or award rendered by the Arbitrators shall be
final and non-appealable, and judgment may be entered upon it in any court of competent jurisdiction. The Arbitrators shall be authorized to award compensatory damages, but shall NOT be authorized (i) to award
non-economic damages, such as for emotional distress, pain and suffering or loss of consortium, (ii) to award punitive damages, or (iii) to reform or modify this Agreement or any other agreements
contemplated hereunder; provided, however, that the damage limitations described in parts (i) and (ii) of this sentence will not apply if such damages are statutorily imposed. 

(c) Costs. Each party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration,
and shall pay an equal share of the fees and costs of the arbitrators; provided, however, the Arbitrators shall be authorized to determine whether a party is the prevailing party, and if so, to award to that prevailing party reimbursement for
any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the Administrator and the Arbitrators. 

(d) Compliance with this Agreement. Unless the parties otherwise agree in writing, during the period of time that
any arbitration proceeding is pending under this Agreement, the parties shall continue to comply with all those terms and provisions of this Agreement that are not the subject of the pending arbitration proceeding. 

10.3 Court Actions. Nothing contained in this Agreement shall deny any party the right to seek injunctive or other
equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing arbitration proceeding.
In addition, either  







 
party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of patents
or other proprietary or intellectual property rights, and no such dispute shall be subject to arbitration pursuant to Section 10.2. 

10.4 Consequence of Patent Challenge. If Celladon challenges the validity or enforceability of any of the Patent Rights
by any opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability thereof in any proceeding before any governmental agency, court or other similar
adjudicative forum (any such proceeding a “Patent Challenge”), such Patent Challenge shall be deemed to be a material breach of this Agreement and AskBio may terminate this Agreement as provided in
Section 8.2, without limiting any right AskBio may have in law or in equity. 
 11. GENERAL PROVISIONS 

11.1 Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the
State of North Carolina, excluding its conflicts of laws principles. 
 11.2 Entire Agreement; Modification.
This Agreement (including the Exhibits hereto) is both a final expression of the parties’ agreement and a complete and exclusive statement with respect to all of its terms. This Agreement supersedes all prior and contemporaneous agreements
and communications, whether oral, written or otherwise, concerning any and all matters contained herein. This Agreement may not be modified or supplemented by any purchase order, change order, acknowledgment, order acceptance, standard terms of
sale, invoice or the like. This Agreement may only be modified or supplemented in a writing expressly stated for such purpose and signed by the parties to this Agreement. 

11.3 Relationship Between the Parties. The parties’ relationship, as established by this Agreement, is solely that
of independent contractors. This Agreement does not create any partnership, joint venture or similar business relationship between the parties. Neither party is a legal representative of the other party, and neither party can assume or create any
obligation, representation, warranty or guarantee, express or implied, on behalf of the other party for any purpose whatsoever. 

11.4 Non-Waiver. The failure of a party to insist upon strict performance of any provision of this Agreement or to
exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a party of a particular
provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such party. 

11.5 Assignment. Except as expressly provided hereunder, neither this Agreement nor any rights or
obligations hereunder may be assigned or otherwise transferred by either party without the prior written consent of the other party (which consent shall not be unreasonably withheld); provided, however, that either party may assign this
Agreement and its rights and obligations hereunder without the other party’s consent in connection with the transfer or sale of all or substantially all of the business of such party to which this Agreement relates to a Third Party, whether by
merger, sale of stock, sale of assets or otherwise. The rights and obligations of  







 
the parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the parties. Any assignment not in accordance with this Agreement shall
be void. In the event that this Agreement is assigned to a third party, Celladon shall notify AskBio so that AskBio may notify UNC. 

11.6 No Third Party Beneficiaries. This Agreement is neither expressly nor impliedly made for the benefit of any party
other than those executing it. 
 11.7 Severability. If, for any reason, any part of this Agreement is
adjudicated invalid, unenforceable or illegal by a court of competent jurisdiction, such adjudication shall not affect or impair, in whole or in part, the validity, enforceability or legality of any remaining portions of this Agreement. All
remaining portions shall remain in full force and effect as if the original Agreement had been executed without the invalidated, unenforceable or illegal part. 

11.8 Notices. Any notice to be given under this Agreement must be in writing and delivered either in person, by any
method of mail (postage prepaid) requiring return receipt, or by overnight courier or facsimile confirmed thereafter by any of the foregoing, to the party to be notified at its address given below, or at any address such party has previously
designated by prior written notice to the other. Notice shall be deemed sufficiently given for all purposes upon the earlier of: (a) the date of actual receipt; (b) if mailed, three business days after the date of postmark; or (c) if
delivered by overnight courier, the next business day the overnight courier regularly makes deliveries.
