conducted. The Company’s Subsidiary is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property makes such qualification or
leasing necessary unless the failure to so qualify has not had and would not reasonably be expected to have a Material Adverse Effect.

2.8      SEC Filings. The Company has filed all reports, schedules, forms, statements
and other documents required to be filed by the Company under the 1933 Act and the 1934 Act, including pursuant to Section 13(a) or 15(d) thereof, for the one year period preceding the date hereof (or such shorter period as the Company was

Property”). There is no pending or, to the Company’s Knowledge, threatened action, suit, proceeding or claim by any Person that the Company’s business or the business of its Subsidiary as now conducted infringes or violates any
patent, trademark, copyright, trade secret or other intellectual property rights of another. To the Company’s Knowledge, there is no existing infringement by another Person of any of the Intellectual Property owned or exclusively licensed by
the Company or its Subsidiary that would have or would reasonably be expected to have a Material Adverse Effect. The Company and its Subsidiary have taken reasonable security measures to protect the secrecy, confidentiality and value of the non-public portions of the Intellectual Property owned or exclusively licensed by the Company or its Subsidiary, except where failure to do so would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect. 
 2.15      Tests and Preclinical and Clinical
Trials. The studies, tests and preclinical and clinical trials conducted by the Company or conducted on behalf of the Company that are described in the SEC Filings were and, if still pending, are being conducted in all material respects in
accordance with the relevant experimental protocols, procedures and controls and all applicable laws; the descriptions of the results of such studies, tests and trials contained in the SEC Filings are accurate and complete and fairly present the
data derived from such studies, tests and trials in all material respects as of the respective dates of such SEC Filings; the Company is not aware of any studies, tests or trials, the results of which the Company believes are materially inconsistent
with the study, test or trial results described or referred to in the SEC Filings when viewed in the context in which such results are described and the clinical state of development; and the Company has not received any notices or written
correspondence from the U.S. Food and Drug Administration or any other federal, state, local or foreign governmental or regulatory authority requiring the termination, suspension or material modification of any studies, tests or preclinical or
clinical trials conducted by or on behalf of the Company. 
 2.16      Environmental
Matters. The Company is not in violation of any material statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or foreign, relating to the use, disposal or release of hazardous or toxic substances
or relating to the protection or restoration of the environment or human exposure to hazardous or toxic substances (collectively, “Environmental Laws”), has not released any hazardous substances regulated by Environmental Law onto
any real property that it owns or operates, and has not received any written notice or claim it is liable for any off-site disposal or contamination pursuant to any Environmental Laws, which violation,
release, notice, claim, or liability would reasonably be expected, individually or in the aggregate, to have a Material 

  
 9 








 
Adverse Effect, and to the Company’s Knowledge, there is no pending or threatened investigation that would reasonably be expected to lead to such a claim. 

2.17      Legal Proceedings. There are no legal, governmental or regulatory
investigations, actions, suits or proceedings pending to which the Company or its Subsidiary are or may reasonably be expected to become a party or to which any property of the Company or its Subsidiary are or may reasonably be expected to become
the subject that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect. 

2.18      Financial Statements. The financial statements included in the SEC Filings
comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing (or to the extent corrected by a subsequent restatement) and present fairly, in
all material respects, the consolidated financial position of the Company as of the dates shown and its consolidated results of operations and cash flows for the periods shown, subject in the case of unaudited financial statements to normal year-end audit adjustments, and such consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles applied on a consistent basis during the periods
involved (“GAAP”) (except as may be disclosed therein or in the notes thereto, and except that the unaudited financial statements may not contain all footnotes required by GAAP, and, in the case of quarterly financial statements,
except as permitted by Form 10-Q under the 1934 Act). 

2.19      Insurance. The Company maintains in full force and effect insurance coverage
that is customary for comparably situated companies for the business being conducted and properties owned or leased by the Company, and the Company reasonably believes such insurance coverage to be adequate against all liabilities, claims and risks
against which it is customary for comparably situated companies to insure. 

2.20      Nasdaq Listing. The Company is in compliance with applicable Nasdaq continued
listing requirements. There are no proceedings pending or, to the Company’s Knowledge, threatened against the Company relating to the continued listing of the Common Stock on Nasdaq and the Company has not received any notice of, nor to the
Company’s Knowledge is there any reasonable basis for, the delisting of the Common Stock from Nasdaq. 

2.21      Brokers and Finders. No Person will have, as a result of the transactions
contemplated by the Transaction Documents, any valid right, interest or claim against or upon the Company or an Investor for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on
behalf of the Company. No Investor shall have any obligation with respect to any fees, or with respect to any claims made by or on behalf of other Persons for fees, in each case of the type contemplated by this Section 2.21
that may be due in connection with the transactions contemplated by this Agreement or the Transaction Documents.

sale of any of the Shares. 
 2.23      No Integrated Offering. Neither the Company
nor any Person acting on its behalf has, directly or indirectly, made any offers or sales of any Company security or solicited any offers to buy any Company security, under circumstances that would adversely affect reliance by the Company on
Section 4(a)(2) and Regulation D for the exemption from registration for the transactions contemplated hereby or would require registration of the Shares under the 1933 Act. 

2.24      Private Placement. Assuming the accuracy of the representations and warranties
of the Investors set forth in Section 3, the offer and sale of the Shares to the Investors as contemplated hereby is exempt from the registration requirements of the 1933 Act. The issuance and sale of the Shares does not
contravene the rules and regulations of Nasdaq. 
 2.25      Foreign Corrupt
Practices. Neither the Company, nor to the Company’s Knowledge, any director, officer, agent, employee or other Person acting on behalf of the Company has, in the course of its actions for, or on behalf of, the Company (i) used any
corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from
corporate funds; (iii) violated or is in violation of in any material respect any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or (iv) made any unlawful bribe, rebate, payoff, influence payment, kickback or

the executive officers or directors of the Company and, to the Company’s Knowledge, none of the employees of the Company is presently a party to any transaction with the Company (other than as holders of stock options and/or restricted stock,
and for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring
payments to or from any officer, director or such employee or, to the Company’s Knowledge, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner. 

2.27      Internal Controls. The Company has established and maintains disclosure
controls and procedures (as defined in Rules 13a-15 and 15d-15 under the 1934 Act), which are designed to ensure that material information relating to the Company,
including its Subsidiary, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities. Since the end of the Company’s most recent audited fiscal year, there have been no
material weaknesses in the Company’s internal control over financial reporting (whether or not remediated) and no change in the Company’s internal 

  
 11 








 
control over financial reporting that has materially affected, or would reasonably be expected to materially affect, the Company’s internal control over financial reporting. The Company is
not aware of any change in its internal controls over financial reporting that has occurred during its most recent fiscal quarter that has materially affected, or would reasonably be expected to materially affect, the Company’s internal control
over financial reporting. 
 2.28      Manipulation of Price. The Company has not
taken, nor will it take, directly or indirectly any action designed to stabilize or manipulate the price of the Common Stock or any security of the Company to facilitate the sale or resale of any of the Shares.

amended. 
 Section 3.      Representations and Warranties of the
Investors. Each of the Investors hereby severally, and not jointly, represents and warrants to the Company that: 

3.1      Organization. Such Investor is either an individual or a duly incorporated or
organized and validly existing corporation, partnership, limited liability company or other legal entity, has all requisite corporate, partnership or limited liability company power and authority, as applicable, to enter into and consummate the
transactions contemplated by the Transaction Documents and to carry out its obligations hereunder and thereunder, and to invest in the Shares pursuant to this Agreement, and, if an entity, is in good standing under the laws of the jurisdiction of
its incorporation or organization. 
 3.2      Authorization. The execution, delivery
and performance by such Investor of the Transaction Documents to which such Investor is a party have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of the
Investor, and each has been duly executed and when delivered will constitute the valid and legally binding obligation of such Investor, enforceable against such Investor in accordance with their respective terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general applicability, relating to or affecting creditors’ rights generally, and general principles of equity. 

3.3      Purchase Entirely for Own Account. The Shares to be received by such Investor
hereunder will be acquired for such Investor’s own account, not as nominee or agent, for the purpose of investment and not with a view to the resale or distribution of any part thereof in violation of the 1933 Act, and such Investor has no
present intention of selling, granting any 

  
 12 








 
participation in, or otherwise distributing the same in violation of the 1933 Act without prejudice, however, to such Investor’s right at all times to sell or otherwise dispose of all or any
part of such Shares in compliance with applicable federal and state securities laws. The Shares are being purchased by such Investor in the ordinary course of its business. Nothing contained herein shall be deemed a representation or warranty by
such Investor to hold the Shares for any period of time. Such Investor is not a broker-dealer registered with the SEC under the 1934 Act or an entity engaged in a business that would require it to be so registered. 

3.4      Investment Experience. Such Investor acknowledges that it can bear the economic
risk and complete loss of its investment in the Shares and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment contemplated hereby. 

3.5      Disclosure of Information. Such Investor has had an opportunity to receive,
review and understand all information related to the Company requested by it and to ask questions of and receive answers from the Company regarding the Company, its business and the terms and conditions of the offering of the Shares, and has
conducted and completed its own independent due diligence. Such Investor acknowledges that copies of the SEC Filings are available on the EDGAR system. Based on the information such Investor has deemed appropriate, it has independently made its own
analysis and decision to enter into the Transaction Documents. Such Investor is relying exclusively on its own investment analysis and due diligence (including professional advice it deems appropriate) with respect to the execution, delivery and
performance of the Transaction Documents, the Shares and the business, condition (financial and otherwise), management, operations, properties and prospects of the Company, including but not limited to all business, legal, regulatory, accounting,
credit and tax matters. Neither such inquiries nor any other due diligence investigation conducted by such Investor shall modify, limit or otherwise affect such Investor’s right to rely on the Company’s representations and warranties
contained in this Agreement. 
 3.6      Restricted Securities. Such Investor
understands that the Shares are characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws
and applicable regulations such securities may be resold without registration under the 1933 Act only in certain limited circumstances. 

3.7      Legends. It is understood that, except as provided below, certificates
evidencing the Shares (or uncertificated interests in the Shares) may bear the following or any similar legend: 

(a)      “THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN


  
 13 








 
OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.” 

(b)      If required by the authorities of any state in connection with the issuance of sale of
the Shares, the legend required by such state authority. 
 3.8      Accredited
Investor. Such Investor is (a) an “accredited investor” within the meaning of Rule 501(a) of Regulation D. Such Investor has executed and delivered to the Company a questionnaire in substantially the form attached hereto as
Exhibit C (the “Investor Questionnaire”), which such Investor represents and warrants is true, correct and complete. Such investor is a sophisticated institutional investor with sufficient knowledge and experience in
investing in private equity transactions to properly evaluate the risks and merits of its purchase of the Shares. 

3.9      No General Solicitation. Such Investor did not learn of the investment in the
Shares as a result of any general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (a) any advertisement, article, notice or other communication published in any newspaper,
magazine, website, or similar media, or broadcast over television or radio, or (b) any seminar or meeting to which such Investor was invited by any of the foregoing means of communications. 

3.10      Brokers and Finders. No Person will have, as a result of the transactions
contemplated by the Transaction Documents, any valid right, interest or claim against or upon the Company or an Investor for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on
behalf of such Investor. 
 3.11      Short Sales and Confidentiality Prior to the Date
Hereof. Other than consummating the transactions contemplated hereunder, such Investor has not, nor has any Person acting on behalf of or pursuant to any understanding with such Investor, directly or indirectly executed any purchases or sales,
including Short Sales, of the securities of the Company during the period commencing as of the time that such Investor was first contacted by the Company or any other Person regarding the transactions contemplated hereby and ending immediately prior
to the date hereof. Notwithstanding the foregoing, in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no
direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio
manager that made the investment decision to purchase the Shares covered by this Agreement. Such Investor, its Affiliates and authorized representatives and advisors who are aware of the transactions contemplated by the Transaction Documents have
maintained the confidentiality of all disclosures made to such Investor in connection with the transactions contemplated by the Transaction Documents (including the existence and terms of such transactions). Notwithstanding the foregoing, for
avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the 

  
 14 








 
identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. 

3.12      No Government Recommendation or Approval. Such Investor understands that no
United States federal or state agency, or similar agency of any other country, has reviewed, approved, passed upon, or made any recommendation or endorsement of the Company or the purchase of the Shares. 

3.13      No Conflicts. The execution, delivery and performance by such Investor of the
Transaction Documents and the consummation by such Investor of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Investor or (ii) conflict with, or constitute a
default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which such Investor is
a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Investor, except in the case of clauses (ii) and (iii) above, for such
conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Investor to perform its obligations hereunder. 

3.14      Residency. Such Investor’s office in which its investment decision with
respect to the Shares was made is located at the address immediately below such Investor’s name on its signature page hereto. 

3.15      Financial Capability. Such Investor has immediately available funds necessary
to consummate the Closing on the terms and conditions contemplated by this Agreement. 

Section 4.      Covenants. 

4.1      Legend Removal.  

(a)      In connection with any sale, assignment, transfer or other disposition of the Shares
by an Investor pursuant to Rule 144 or pursuant to any other exemption under the 1933 Act such that the purchaser acquires freely tradable shares and upon compliance by the Investor with the requirements of this Agreement, if requested by the
Investor, the Company shall cause the transfer agent for the Common Stock (the “Transfer Agent”) to remove any restrictive legends related to the book entry account holding such Shares and make a new, unlegended entry for such book
entry Shares sold or disposed of without restrictive legends within two Trading Days of any such request therefor from such Investor, provided that the Company has timely received from the Investor customary representations and other
documentation reasonably acceptable to the Company in connection therewith. 

(b)      Subject to receipt from the Investor by the Company and the Transfer Agent of
customary representations and other documentation reasonably acceptable to the Company and the Transfer Agent in 

  
 15 








 
connection therewith, upon the earliest of such time as the Shares (i) have been sold or transferred pursuant to an effective registration statement, (ii) have been sold pursuant to
Rule 144, or (iii) are eligible for resale under Rule 144(b)(1) or any successor provision (such earliest date, the “Effective Date”), the Company shall, in accordance with the provisions of this
Section 4.1(b) and within three Trading Days of any request therefor from an Investor accompanied by such customary and reasonably acceptable documentation referred to above, (A) deliver to the Transfer Agent
irrevocable instructions that the Transfer Agent shall make a new, unlegended entry for such book entry Shares, and (B) cause its counsel to deliver to the Transfer Agent one or more opinions to the effect that the removal of such legends in
such circumstances may be effected under the 1933 Act if required by the Transfer Agent to effect the removal of the legend in accordance with the provisions of this Agreement. The Company agrees that following the Effective Date or at such time as
such legend is no longer required under this Section 4.1, it will, within three Trading Days of the delivery by an Investor to the Company or the Transfer Agent of a certificate representing shares issued with a restrictive
legend and receipt from the Investor by the Company and the Transfer Agent of the customary representations and other documentation reasonably acceptable to the Company and the Transfer Agent in connection therewith that is referred to above,
deliver or cause to be delivered to such Investor a certificate representing such Shares (or uncertificated interest therein) that is free from all restrictive and other legends. Shares subject to legend removal hereunder may be transmitted by the
Transfer Agent to the Investor by crediting the account of the Investor’s prime broker with the DTC system as directed by such Investor. The Company shall be responsible for the fees of its Transfer Agent and all DTC fees associated with such
issuance. 
 (c)      Each Investor, severally and not jointly with the other Investors,
agrees with the Company (i) that such Investor will sell any Shares pursuant to either the registration requirements of the 1933 Act, including any applicable prospectus delivery requirements, or an exemption therefrom, (ii) that if Shares
are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein and (iii) that if, after the effective date of the registration statement covering the resale of the Shares, such
registration statement is not then effective and the Company has provided notice to such Investor to that effect, such Investor will sell Shares only in compliance with an exemption from the registration requirements of the 1933 Act. 

4.2      Short Sales and Confidentiality After the Date Hereof. Each Investor covenants
that neither it nor any Affiliates acting on its behalf or pursuant to any understanding with it will execute any Short Sales during the period from the date hereof until the earlier of such time as (i) the transactions contemplated by this
Agreement are first publicly announced or (ii) this Agreement is terminated in full. Each Investor covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company, such Investor will
maintain (and will cause its Affiliates, authorized representatives and advisors who are aware of the transactions contemplated by the Transaction Documents) to maintain the confidentiality of all disclosures made to it in connection with the
transactions contemplated by the Transaction Documents (including the existence and terms of such transactions). Each 

  
 16 








 
Investor understands and acknowledges that the SEC currently takes the position that coverage of Short Sales of shares of the Common Stock “against the box” prior to effectiveness of a
resale registration statement with securities included in such registration statement would be a violation of Section 5 of the 1933 Act, as set forth in Item 239.10 of the Securities Act Rules Compliance and Disclosure Interpretations compiled
by the Office of Chief Counsel, Division of Corporation Finance, and covenants that neither it nor any Affiliates acting on its behalf or pursuant to any understanding with it will execute any such Short Sales. 

Section 5.      Conditions to Closing. 

5.1      Conditions to the Investors’ Obligations. The obligation of

(b)      In the event of termination by the Company or any Investor of its obligations to
effect the Closing pursuant to this Section 5.3, written notice thereof shall be given to the other Investors by the Company and the other Investors shall have the right to terminate their obligations to effect the Closing
upon written notice to the Company and the other Investors. Nothing in this Section 5.3 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or
the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents.

 6.8      Waiver. Waiver by the Company or any Investor of a
breach hereunder by any Investor or the Company, respectively, shall not be construed as a waiver of any subsequent breach of the same or any other provision. No delay or omission by a party in exercising or availing itself of any right, power or
privilege hereunder shall preclude the later exercise of any such right, power or privilege by such party. No waiver shall be effective unless made in writing with specific reference to the relevant provision(s) of this Agreement and signed by a
duly authorized representative of the party granting the waiver. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative. 

6.9      Amendments. Any term of this Agreement may be amended or terminated only with
the written consent of the Company and the Investors representing a majority of the Shares. Notwithstanding the foregoing, this Agreement may not be amended and the observance of any term of this Agreement may not be waived with respect to any
Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. 

6.10      Severability. If one or more of the terms or provisions of this Agreement is
held by a court of competent jurisdiction to be void, invalid, or unenforceable in any situation in any jurisdiction, such holding shall not affect the validity or enforceability of the 

  
 20 








 
remaining terms and provisions hereof or the validity or enforceability of the void, invalid, or unenforceable term or provision in any other situation or in any other jurisdiction, and the term
or provision shall be considered severed from this Agreement solely for such situation and solely in such jurisdiction, unless the void, invalid, or unenforceable term or provision is of such essential importance to this Agreement that it is to be
reasonably assumed that the parties hereto would not have entered into this Agreement without the void, invalid, or unenforceable term or provision. If the final judgment of such court declares that any term or provision hereof is void, invalid, or
unenforceable, the parties hereto parties hereto agree to: (a) reduce the scope, duration, area, or applicability of the term or provision or to delete specific words or phrases to the minimum extent necessary to cause such term or provision as
so reduced or amended to be enforceable; and (b) make a good-faith effort to replace any void, invalid, or unenforceable term or provision with a valid and enforceable term or provision such that the objectives contemplated by the parties
hereto when entering this Agreement may be realized. 
 6.11      Entire Agreement.
This Agreement and the Registration Rights Agreement constitute the full and entire understanding and agreement between the parties with respect to the subject matter hereof and thereof, and any other written or oral agreement relating to the
subject matter hereof or thereof existing among the parties are expressly canceled. 

6.12      Specific Enforcement. The parties hereto agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific intent or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to
prevent or cure breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they may be entitled by law or equity. 

6.13      Exclusive Jurisdiction; Venue. Each of the parties hereto irrevocably agrees
that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder
brought by another party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery, or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any federal
court within the State of Delaware, or, if both the Delaware Court of Chancery and the federal courts within the State of Delaware decline to accept jurisdiction over a particular matter, any other state court within the State of Delaware, and, in
each case, any appellate court therefrom. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of
the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably
waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason
other than the failure to serve 

  
 21 








 
in accordance with this Section 6.13, (b) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process
commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by the applicable Law, any claim
that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or
by such courts. Each of the parties hereto agrees that service of process upon such party in any such action or proceeding shall be effective if such process is given as a notice in accordance with Section 6.5. 

6.14      Publicity. Except as set forth below, no public release or announcement
concerning the transactions contemplated hereby shall be issued by any Investor without the prior consent of the Company, except as such release or announcement may be required by law or the applicable rules or regulations of any securities exchange
or securities market, in which case the Investors shall allow the Company reasonable time to comment on such release or announcement in advance of such issuance. Notwithstanding the foregoing, each Investor may identify the Company and the value of
such Investor’s security holdings in the Company in accordance with applicable investment reporting and disclosure regulations or internal policies without prior notice to or consent from the Company (including, for the avoidance of doubt,
filings pursuant to Sections 13 and 16 of the 1934 Act). 
 6.15      Survival. The
representations, warranties, covenants and agreements contained in this Agreement shall survive the Closing of the transactions contemplated by this Agreement for a period of one year following the Closing Date. 

6.16      Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY
WAIVES TO THE EXTENT PERMITTED BY APPLICABLE LAW ANY AND ALL RIGHT TO A TRIAL BY JURY IN ANY DIRECT OR INDIRECT ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY
(A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) MAKES
THIS WAIVER VOLUNTARILY, AND (C) ACKNOWLEDGES THAT EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS CONTAINED IN THIS SECTION 6.16.
