 5.4 Royalties. 

(a) Net Sales Royalty. During the Royalty Term, Arrys shall pay to AskAt royalties equal to [***] (the “Royalty Rate”)

(ii) AskAt shall have the right to engage, at its own cost and expense, subject to this Section 5.4, an independent
internationally recognized public accounting firm chosen by AskAt and reasonably acceptable to Arrys (which accounting firm shall not be the external auditor of AskAt, shall not have been hired or paid on a contingency basis and shall have
experience auditing pharmaceutical companies) (a “CPA Firm”) to conduct an audit of Arrys for the purposes of confirming Arrys’s compliance with the Net Sales Royalty provisions of this Agreement. 

(iii) The CPA Firm shall be given access to and shall be permitted to examine such books and records of Arrys, and to interview
employees of Arrys, as the CPA Firm shall reasonably request, upon [***] prior written notice having been given by AskAt, during regular business hours, for the sole purpose of determining compliance with the Net Sales Royalty provisions of this
Agreement. Prior to any such examination taking place, the CPA Firm shall enter into a confidentiality agreement reasonably acceptable to Arrys with respect to the Know-How to which they are given access and
shall not contain in its report or otherwise disclose to AskAt or any Third Party any information other than the existence of a discrepancy between the Net Sales Royalty paid by Arrys and the amounts payable hereunder and the amount of such
discrepancy. 
 (iv) The CPA Firm shall discuss its preliminary findings with Arrys prior to the preparation by the CPA firm
of its final report. The CPA Firm shall provide both AskAt and Arrys simultaneously the written report of the CPA Firm with respect to its findings. In the event of any dispute between AskAt and Arrys regarding the findings of any such inspection or
audit, the Parties shall initially attempt in good faith to resolve the dispute amicably between themselves, and if the Parties are unable to resolve such dispute within [***] after delivery to both Parties of the CPA Firm’s report, the Parties
shall select one (1) internationally recognized independent certified public accounting firm (other than the CPA Firm) to resolve the dispute, and such accounting firm’s determination shall be binding on both Parties absent manifest error
by such accounting firm. 
 (v) Within [***] after completion of the CPA Firm’s audit, Arrys shall pay to AskAt any
undisputed deficiency in the Net Sales Royalty amount determined by the CPA Firm, plus interest at the rate set forth in Section 5.7 from the date originally due. If the report of the CPA Firm shows that Arrys overpaid, then Arrys shall
be entitled to off-set such overpayment against any Net Sales Royalty owed to AskAt then or in any subsequent period. If the report of the CPA Firm shows that Arrys underpaid and if such discrepancy exceeds
the greater of [***] of the amount audited or [***], then all the fees and expenses of the CPA Firm in performing such audit shall be paid by Arrys.

 19 













 (vii) AskAt shall not have the right to audit Arrys Sublicensee(s) directly,
but in connection with an audit of Arrys under this Section 5.4(d), AskAt shall have the right to cause Arrys to audit the applicable Arrys Sublicensee(s) using the CPA Firm conducting the audit under this Section 5.4(d).

 (e) Mode of Payment; Currency Conversion. All payments under this Agreement, shall be made by deposit of U.S. Dollars in the
requisite amount to such bank account as AskAt may from time to time designate by notice to Arrys. For the purpose of calculating any sums due under this Agreement (including the calculation of Net Sales expressed in currencies other than U.S.
Dollars), Arrys shall convert any amount expressed in a foreign currency into U.S. Dollar equivalents using Arrys’s (or its Affiliate’s or Arrys Sublicensee’s standard conversion methodology consistent with U.S. generally
accepted accounting principles (GAAP) or international financial reports standards (IFRS), as applicable, in a manner consistent with such Person’s normal practices used to prepare its audited financial reports; provided that, such
practices use a widely accepted source of published exchange rates. Notwithstanding the foregoing, the currency conversion methodology to be used for calculating any sums due under this Agreement in connection with any sales or other transfers of
Royalty-Bearing Product by any Arrys Sublicensee shall be the methodology agreed to by Arrys and any of its Affiliates with such Arrys Sublicensee. Any reporting of currency conversion hereunder shall reflect the currency conversion methodology
agreed to by Arrys and any of its Affiliates with a Arrys Sublicensee. 
 (f) Blocked Payments. In the event that, by reason of
applicable Laws or regulations in any country, it becomes impossible or illegal for Arrys or its Affiliates to transfer, or have transferred on its behalf, royalties or other payments to AskAt, such royalties or other payments shall be deposited in
local currency in the relevant country to the credit of AskAt in a recognized banking institution designated by AskAt or, if none is designated by AskAt within a period of [***], in a recognized banking institution selected by Arrys. 

(g) Taxes. Where required by Applicable Law, Arrys shall have the right to withhold applicable taxes from any payments to be made by
Arrys to AskAt pursuant to this Agreement; provided that, to the extent allowed by Applicable Law, prior to such withholding, Arrys shall give written notice of its intention to withhold and allow AskAt reasonably sufficient time to provide
any documentation or forms to the applicable Governmental Authority to minimize or eliminate such withholding. Arrys shall provide AskAt with receipts from the appropriate taxing authority for all payments of taxes withheld and paid by Arrys to such
authorities on behalf of AskAt. AskAt shall have the right to appeal to the appropriate taxing authority any such withholding and payment of such taxes. 

(h) No Other Compensation. Other than as explicitly set forth (and as applicable) in this Agreement, Arrys shall not be obligated to
pay any additional fees, milestone payments, royalties or other payments of any kind to or on behalf of AskAt or its Affiliates under this Agreement. 

5.5 Right to Set-off. Either Party shall have the right to deduct from amounts otherwise
payable hereunder to the other Party any amounts payable to such Party (or its Affiliates) from the other Party (or its Affiliates) under this Agreement that have been determined by a final, non-appealable
judgment by a court of competent jurisdiction or otherwise agreed to by the Parties. 

  
 20 













 5.6 Right to terminate. Arrys’s failure to make any undisputed payments required
hereunder, shall be a material breach hereof, subject to Section 10.3(a). 
 5.7 Late payment. Any payment not delivered
on time shall accrue interest from the date due until paid in full at the rate of the lower of [***] or the highest rate allowed under Applicable Laws.

 8.2 Indemnification by Arrys. Subject to the remainder of this Article 8, Arrys shall
defend, indemnify, and hold AskAt, its Affiliates, subcontractors, and licensees, and each of their respective officers, directors, employees, and agents (the “AskAt Indemnitees”) harmless from and against any and all liabilities,
losses, costs, damages, fees, expenses or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such AskAt Indemnitees, all to the extent resulting from any claims, suits,

8.3 Indemnification Procedures. The Party claiming indemnity under this Article 8 (the “Indemnified Party”)
shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of the claim, suit, proceeding or cause of action for which indemnity is being sought
(“Claim”). The Indemnifying Party’s obligation to defend, indemnify, and hold harmless pursuant to Section 8.1 or Section 8.2, as applicable, shall be reduced to the extent the Indemnified Party’s
delay in providing notification pursuant to the previous sentence results in material prejudice to the Indemnifying Party; provided, however, that the failure by an Indemnified Party to give such notice or otherwise meet its obligations under
this Section 8.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement. At its option, the Indemnifying Party may assume the defense and have exclusive control, at its own expense, of any Claim
for which indemnity is being sought by giving written notice to the Indemnified Party within [***] after receipt of the notice of the Claim, provided that (a) it agrees to indemnify the Indemnified Party from and against all losses the
Indemnified Party may suffer arising out of the Claim; (b) the Claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Party; (c) the Claim does not relate to any criminal or
regulatory enforcement proceeding; and (d) the Indemnifying Party conducts the defense of the Claim diligently. The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in
connection with the defense. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the
defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim that adversely affects the Indemnified Party’s rights without the prior written consent of the Indemnified Party, not to be unreasonably
withheld, conditioned or delayed, unless the settlement involves only the payment of money. The Indemnified Party shall not settle any such Claim that adversely affects the Indemnifying Party’s rights without the prior written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (i) the Indemnified Party may defend against, and
consent to the entry of any judgment or enter into any settlement with respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the
Indemnifying Party in connection therewith), and (ii) the Indemnified Party reserves any right it may have under this Article 8 to obtain indemnification from the Indemnified Party.

 8.4 Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER
FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES OF ANY KIND ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT OR ANY CLAIMS ARISING HEREUNDER, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (WHETHER IN
CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE), REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 8.4 IS INTENDED TO OR SHALL LIMIT OR RESTRICT
(A) THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 8.1 OR SECTION 8.2, (B) DAMAGES AVAILABLE IN THE CASE OF A PARTY’S FRAUD, GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT, OR (C) DAMAGES
AVAILABLE TO A PARTY FOR A BREACH BY THE OTHER PARTY OF ARTICLE 4 OR THE CONFIDENTIALITY OBLIGATIONS UNDER ARTICLE 9. 

8.5 Insurance. During the Term, Arrys shall, at its individual sole expense, obtain and maintain commercially reasonable insurance or
maintain a commercially reasonable program of self-insurance. Each Party shall also maintain any mandatory insurance, including but not limited to workers compensation coverage, in accordance with all Applicable Laws and regulations. Each Party
shall provide to the other Party, on request, certificates of insurance evidencing the minimum required insurance, including notice of cancellation to be provided in accordance with the terms of the insurance policies. 

ARTICLE 9 

CONFIDENTIALITY 
 9.1
Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that the receiving Party shall keep confidential and shall not publish or otherwise disclose or use for
any purpose other than as provided for in this Agreement any information and materials provided to it by or on behalf of the other Party or its Affiliates or generated pursuant to this Agreement (collectively, “Confidential
Information”). For clarity, Confidential Information of a Party or its Affiliates shall include, without limitation, all information and materials disclosed by such Party or its Affiliates or their respective designees that (a) is
marked as “Confidential,” “Proprietary” or with similar designation at the time of disclosure or (b) by its nature can reasonably be expected to be considered Confidential Information by the recipient. Information disclosed
orally shall not be required to be identified as such to be considered Confidential Information. The terms of this Agreement shall be deemed to be the Confidential Information of both Parties. Notwithstanding the foregoing, Confidential Information
shall not include any information to the extent that it can be established by written documentation by the receiving Party that such information: 

(a) was already known to the receiving Party, other than under an obligation of confidentiality (except to the extent such obligation has
expired or an exception is applicable under the relevant agreement pursuant to which such obligation was established), at the time of disclosure; 

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party; 

  
 34 













 (c) became generally available to the public or otherwise part of the public domain after
its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement; 
 (d) was independently
developed by the receiving Party as demonstrated by written documentation prepared contemporaneously with such independent development; or 

(e) was disclosed to the receiving Party, other than under an obligation of confidentiality (except to the extent such obligation has expired
or an exception is applicable under the relevant agreement pursuant to which such obligation was established), by a Third Party who had no obligation to the disclosing Party not to disclose such information to others. 

9.2 Authorized Disclosure. Except as expressly provided otherwise in this Agreement, each Party may use and disclose Confidential
Information of the other Party solely as follows: 
 (a) under appropriate confidentiality provisions substantially equivalent to those in
this Agreement: 
 (i) in connection with the performance of its obligations or as reasonably necessary or useful in the
exercise of its rights under this Agreement, including the right to grant licenses or sublicenses as permitted hereunder; 

(ii) in the case of Arrys as the receiving Party, to actual or potential (sub)licensees, acquirers or assignees, collaborators,
investment bankers, investors or lenders, in each case, on a need to know basis; 
 (iii) in the case of AskAt as the
receiving Party, to actual or potential acquirers or assignees, collaborators, investment bankers, investors or lenders, in each case, on a need to know basis; and 

(iv) in the case of AskAt as the receiving Party, to actual or potential licensees (including an actual or potential licensee
who is a Arrys Sublicensee coming into a direct license as provided for in this Agreement) solely as is reasonably necessary for each such disclosee to conduct technical or legal due diligence in connection with the proposed transaction with AskAt;
provided that in no event shall such disclosure include any Confidential Information of Arrys other than the scope of Licensed Technology, Licensed Compounds, Licensed Products, in the Field and in the Territory, 

(b) to the extent such disclosure is to a Governmental Authority as reasonably necessary in filing or prosecuting Patent, copyright and
trademark applications, prosecuting or defending litigation, complying with applicable governmental regulations with respect to performance under this Agreement, obtaining Regulatory Approval or fulfilling
post-approval regulatory obligations for the Licensed Compounds or Licensed Products, or otherwise required by Applicable Law; provided, however, that if a Party is required by Applicable Law to make
any such disclosure of the other Party’s Confidential Information it shall, except where impracticable for necessary disclosures, give reasonable advance notice to the other Party of such disclosure requirement and, in each of the foregoing,
shall use its reasonable efforts to secure confidential treatment of such Confidential Information required to be disclosed and shall only disclosed that Confidential Information that is required to be disclosed; 

  
 35 













 (c) to advisors (including lawyers and accountants) on a need to know basis, in each case
under appropriate confidentiality provisions or professional standards of confidentiality substantially equivalent to those of this Agreement; or 

(d) to the extent mutually agreed to by the Parties. 

In the event that a receiving Party discloses Confidential Information of the other Party pursuant to the foregoing provisions of this
Section 9.2, the receiving Party shall be primarily liable to the other Party for any act or omission of a disclosee to whom the receiving Party provides the disclosing Party’s Confidential Information to the same extent as if such
act or omission of a disclose were an act or omission of the receiving Party. Notwithstanding the foregoing, the Parties shall agree upon a joint press release to announce this Agreement in a form to be mutually agreed by the Parties; thereafter,
each Party may each disclose to Third Parties the information contained in such press release without the need for further approval by the other. Notwithstanding the foregoing, if a Party is required by Applicable Law to make a disclosure of the
terms of this Agreement in a filing with or other submission to the SEC or foreign equivalent, any stock exchange or market, including publicly disclosing or filing this Agreement as a “material agreement” in accordance with Applicable
Laws or applicable stock exchange regulations, and (A) such Party has provided copies of the disclosure to the other Party as far in advance of such filing or other disclosure as is reasonably practicable under the circumstances, (B) such
Party has promptly notified the other Party in writing of such requirement and any respective timing constraints, and (C) such Party has given the other Party a reasonable time under the circumstances from the date of notice by such Party of
the required disclosure to comment upon, request confidential treatment or approve such disclosure, then such Party shall have the right to make such public disclosure at the time and in the manner reasonably determined by its counsel to be required
by Applicable Law. Notwithstanding anything to the contrary herein, it is hereby understood and agreed that if a Party seeking to make a disclosure to the SEC as set forth in this Section 9.2, and the other Party provides comments within
the respective time periods or constraints specified herein or within the respective notice, the Party seeking to make such disclosure or its counsel, as the case may be, shall in good faith (1) consider incorporating such comments and
(2) use reasonable efforts to incorporate such comments, limit disclosure or obtain confidential treatment to the extent reasonably requested by the other Party. Each Party shall have the right to issue additional press releases or to make
public disclosures with the prior written agreement of the other Party. 
 9.3 Attorney-Client
Privilege. Neither Party is waiving, nor shall be deemed to have waived or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges as a
result of disclosing information pursuant to this Agreement, or any of its Confidential Information (including Confidential Information related to pending or threatened litigation) to the receiving Party, regardless of whether the disclosing Party
has asserted, or is or may be entitled to assert, such privileges and protections. The Parties: (a) share a common legal and commercial interest in such disclosure that is subject to such privileges and protections; (b) are or may become
joint defendants in proceedings to which the information covered by such protections and privileges relates; (c) intend that such privileges and protections remain intact should either Party become subject to any actual or threatened proceeding
to which the disclosing Party’s Confidential Information covered by such protections and privileges relates; and (d) intend that after the Effective Date both the receiving Party and the disclosing Party shall have the right to assert such
protections and privileges.

non-terminating Party reasonably disputes in good faith the right of the other Party to terminate this Agreement for any reason other than Arrys’s right to terminate for convenience pursuant to
Section 10.2, and such non-terminating Party provides the terminating Party written notice of such dispute with reasonable justification for such dispute within [***] after the terminating Party’s
notice, as applicable, then the terminating Party shall not have the right to terminate this Agreement unless and until a court, in accordance with Article 11, has determined that the terminating Party has the right to terminate this Agreement in

Sublicensee and AskAt shall enter into a direct license agreement under the Licensed Technology within the scope of the relevant Arrys Sublicense, on the same terms as set forth in this Agreement and AskAt agrees to negotiate in good faith the final
form of such license agreement;

Party hereunder that is in the possession or control of such Party (or any of its Affiliates, sublicensees or subcontractors), except that such Party shall have the right to retain [***] copy of Confidential Information of such other Party strictly
for legal purposes; and 
 (iv) Arrys shall, and shall cause each of its Affiliates and each Arrys Sublicensee to, provide to
AskAt, without any charge, a copy of or reasonable access to any Know-How or Inventions Controlled by Arrys, or any of its Affiliates or any Arrys Sublicensee that were developed, created, conceived or reduced
to practice by or on behalf of such Person in the course of the Development and Commercialization of Licensed Compound and Licensed Product (“Related Know-How and Inventions”). Arrys shall

sublicenseable, worldwide, royalty free, fully paid up, perpetual and irrevocable license to Exploit the Related Know-How and Inventions Controlled by such Person without any restriction to the extent

(b) Upon termination of Section 6.1(b) by Arrys pursuant to Section 10.2(b), the license grant set forth in
Section 6.1(b) shall terminate.

Parties agree that Arrys, as licensee of certain rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of the commencement of a
bankruptcy proceeding by or against AskAt under the U.S. Bankruptcy Code, Arrys shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property licensed to Arrys and all embodiments of such intellectual

of its obligations under this Agreement or (b) if not delivered under clause (a), following the rejection of this Agreement by AskAt upon written request therefor by Arrys. 

10.7 Survival. Notwithstanding anything to the contrary, the following provisions shall survive and apply after expiration or

accordance with the foregoing shall terminate upon expiration or termination of this Agreement and be of no further force and effect. Termination or expiration of this Agreement for any reason shall not constitute a waiver or release of, or
otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or otherwise, that a Party may have hereunder or that may arise out of or in connection with such termination or expiration. 

ARTICLE 11 
 DISPUTE
RESOLUTION 
 11.1 Disputes. Except as otherwise expressly set forth in this Agreement, disputes of any nature arising under,
relating to, or in connection with this Agreement (“Disputes”) shall be resolved pursuant to this Article 11. 

11.2 Dispute Escalation. In the event of a Dispute between the Parties, the Parties shall first attempt to resolve such Dispute by
negotiation and consultation between themselves. In the event that such Dispute is not resolved on an informal basis within [***] from receipt of the written notice of a Dispute, either party may, by written notice to the other, have such Dispute
referred to the Chief Executive Officer of each Party (or the designee of the Chief Executive 

  
 39 













 
Officer, which designee is required to have decision-making authority on behalf of such Party), who shall attempt to resolve such Dispute by negotiation and consultation for a [***] period
following receipt of such written notice. 
 11.3 Arbitration. In the event the Parties have not resolved such Dispute within [***]
of receipt of the written notice referring such Dispute pursuant to Section 11.2, either Party may at any time after such [***] period submit such Dispute to be finally settled by arbitration administered in accordance with the
procedural rules of the American Arbitration Association (the “AAA”) in effect at the time of submission, as modified by this Section 11.3. The arbitration shall be governed by the Laws of the State of New York. The
arbitration shall be heard and determined by [***] arbitrators who are retired judges or attorneys with at least [***] of relevant experience in the pharmaceutical and biotechnology industry, each of whom shall be impartial and independent. Each
Party shall appoint [***] arbitrator and the [***] arbitrator shall be selected by the [***] Party-appointed arbitrators, or, failing agreement within [***] following appointment of the second arbitrator, by the AAA. Such arbitration shall take
place in New York, New York. The arbitration award so given shall, absent manifest error, be a final and binding determination of the Dispute, shall be fully enforceable in any court of competent jurisdiction, and shall not include any damages
expressly prohibited by Section 8.4. Fees, costs and expenses of arbitration are to be divided by the Parties in the following manner: each Party shall pay for the arbitrator it chooses and the Parties shall share payment for the third
arbitrator. Except in a proceeding to enforce the results of the arbitration or as otherwise required by law, neither Party nor any arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written
consent of both Parties. 
 11.4 Injunctive Relief. Notwithstanding the dispute resolution procedures set forth in this Article
11, in the event of an actual or threatened breach of this Agreement, the aggrieved Party may seek provisional equitable relief (including restraining orders, specific performance or other injunctive relief), without first submitting to any
dispute resolution procedures hereunder. 
 11.5 Tolling. 

(a) The Parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel and laches), as well as all time
periods in which a party must exercise rights or perform obligations hereunder, shall be tolled once the dispute resolution procedures set forth in this Article 11 have been initiated and for so long as they are pending, and the Parties shall
cooperate in taking all actions reasonably necessary to achieve such a result. 
 (b) In addition, during the pendency of any Dispute under
this Agreement initiated before the end of any applicable cure period: 
 (i) this Agreement shall remain in full force and
effect, 
 (ii) the provisions of this Agreement relating to termination for material breach with respect to such Dispute
shall not be effective, 
 (iii) the time period for cure under Section 10.3(a) as to any termination notice
given prior to the initiation of arbitration shall be tolled, 
 (iv) any time periods to exercise rights or perform
obligations shall be tolled; and 

  
 40 













 (v) neither Party shall issue a notice of termination pursuant to this
Agreement based on the subject matter of the arbitration, until the arbitral tribunal has confirmed the material breach and the existence of the facts claimed by a Party to be the basis for the asserted material breach; provided, that if such
breach can be cured by the taking of specific remedial actions, the defaulting Party shall have a reasonable period of time to undertake and complete such remedial actions before any such notice of termination can be issued. Further, with respect to
any time periods that have run during the pendency of the Dispute, the applicable Party shall have a reasonable period of time to exercise any rights or perform any obligations affected by the running of such time periods.

this Agreement. References to any Sections include Sections and subsections that are part of the related Section (e.g., a section numbered “Section 3.2” would be part of “Section 3”, and references to
“Section 3.2” would also refer to material contained in the subsection described as “Section 3.2(a)”). Unless otherwise stated, dollar amounts set forth in this Agreement are U.S. dollars. 

12.6 Assignment. Neither Party may assign or transfer (whether by operation of Applicable Law or otherwise) this Agreement or any
rights or obligations hereunder without the prior written consent of the other, except that following prior written notice to the other Party, (a) Arrys may make such an assignment without AskAt’s consent to an Affiliate or to a successor
to all or substantially all of the business or assets to which this Agreement relates, whether in a merger, sale of stock, sale of assets, reorganization or other transaction and (b) AskAt may make such an assignment without Arrys’s
consent to a successor to all or substantially all of the business or assets to which this Agreement relates, including the assets related to the Licensed Compound or Licensed Products, whether in a merger, sale of stock, sale of assets,
reorganization or other transaction. Any permitted successor or assignee of rights or obligations hereunder shall expressly assume performance of such rights or obligations (and in any event, any Party assigning this Agreement to an Affiliate shall
remain bound by the terms and 

  
 42 













 
conditions hereof and any Party assigning this Agreement to a Third Party other than Affiliate shall remain bound by the terms and conditions of Article 9). Any permitted assignment shall
be binding on and inure to the benefit of the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 12.6 shall be null, void and of no legal effect. 

12.7 Performance by Affiliates. Each Party may discharge any obligations and exercise any right hereunder through any of its
Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any
breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such
Party’s Affiliate. 
 12.8 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and
to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 
 12.9
Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by an arbitrator or by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered
severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives
contemplated by the Parties when entering into this Agreement may be realized. 
 12.10 No Waiver. Any delay in enforcing a
Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an
express written and signed waiver relating to a particular matter for a particular period of time. 
 12.11 Independent Contractors.
Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to
create the relationship of partners, principal and agent, or joint-venture partners between the Parties. 
 12.12 Counterparts. This
Agreement may be executed in one (1) or more counterparts, by facsimile, pdf or other electronic format, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

12.13 Choice of Law. This Agreement shall be governed by, and enforced and construed in accordance with, the laws of the State of New
York, without regard to its conflicts of law provisions.
