free and clear of any security interest, mortgage, pledge, lien, encumbrance or adverse claim.

4.21 No Integrated Offering. Neither the Company nor its subsidiaries nor any Person acting on their 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) for the exemption from

 4.22 Private
Placement. Assuming the accuracy of the representations and warranties of the Investors set forth in Section 5, the offer and sale of the Shares to the Investors as contemplated hereby is exempt from the registration requirements of the

its subsidiaries, 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
significant deficiencies or material weaknesses in the Company’s internal control over financial reporting (whether or not remediated) and no change in the Company’s internal 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

any information with respect to the transactions contemplated hereby that constitutes or would reasonably be expected to constitute material, non-public information concerning the Company or its subsidiaries,
other than with respect to the transactions contemplated hereby and as described on the Disclosure Schedule, which will be disclosed in the Press Release (as defined below). The SEC Filings and the slide presentation presented to the Investors by
the Company in connection with the offer and sale of the Shares, when considered together, do not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, in light
of the circumstances under which they were made, not misleading. The Company understands and confirms that the Investors will rely on the foregoing representations in effecting transactions in securities of the Company. 

4.27 Required Filings. Except for the transactions contemplated by this Agreement, including the acquisition of the Shares contemplated
hereby, no event or circumstance has occurred or information exists with respect to the Company or its business, properties, operations or financial condition, which, under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or disclosed (assuming for this purpose that the SEC Filings are being incorporated by reference into an effective registration statement filed by the Company under the 1933
Act). 
 4.28 Investment Company. The Company is not required to be registered as, and is not an Affiliate of, and immediately
following the Closing will not be required to register as, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

4.30 Anti-Bribery and Anti-Money Laundering Laws. Each of the Company, its subsidiaries and any of their respective officers,
directors, supervisors, managers, agents, or employees, are and have at all times been in compliance with and its participation in the offering will not violate: (A) anti-bribery laws, including but not limited to, any applicable law, rule, or
regulation of any locality, including but not limited to any law, rule, or regulation promulgated to implement the OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, signed December 17,
1997, including the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.K. Bribery Act 2010, or any other law, rule or regulation of similar purposes and scope or (B) anti-money laundering laws, including but not limited to,
applicable federal, state, international, foreign or other laws, regulations or government guidance regarding anti-money laundering, including, without limitation, Title 18 U.S. Code section 1956 and 1957, the Patriot Act, the Bank Secrecy Act, and
international anti-money laundering principles or procedures by an intergovernmental group or organization, such as the Financial Action Task Force on Money Laundering, of which the United States is a member and with which designation the United
States representative to the group or organization continues to concur, all as amended, and any executive order, directive, or regulation pursuant to the authority of any of the foregoing, or any orders or licenses issued thereunder.

 4.31 Compliance. The Company is not (i) in default under or in violation of (and
no event has occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company under), nor has the Company received written notice of a claim that it is in default under or that it is in violation
of, any indenture, loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or violation has been waived), (ii) in violation of any
judgment, decree or order of any court, arbitrator or governmental body specifically naming the Company or (iii) in violation of any statute, rule, ordinance or regulation of any governmental authority, including without limitation all foreign,
federal, state and local laws relating to taxes, environmental protection, occupational health and safety, product quality and safety and employment and labor matters, except in each case as would not have or reasonably be expected to result in a
Material Adverse Effect. 
 4.32 No Bad Actors. No “bad actor” disqualifying event described in
Rule 506(d)(1)(i)-(viii) of the 1933 Act (a “Disqualification Event”) is applicable to the Company or, to the Company’s knowledge, any Company Covered Person, except (i) for a Disqualification Event as to which
Rule 506(d)(2)(ii—iv) or (d)(3) is applicable and (ii) no such representation is made with respect to the Placement Agents, or any of their respective general partners, managing members, directors, executive officers or other
officers. 
 4.33 Sufficient Proceeds. The cash proceeds to be received by the Company upon the closing of the transactions
contemplated by the Commitment Letter, when taken together with (i) the net cash proceeds to be received by the Company pursuant to the terms hereof and (ii) the cash currently reflected on the Company’s most recent balance sheet, are
sufficient to satisfy the cash component of the total consideration required to be paid by the Company to the stockholders of Archer pursuant to the terms of the Merger Agreement. 

4.34 Merger Agreement. The Company has no reason to believe that the representations and warranties of Archer contained in the Merger
Agreement are untrue in any material respect.

general equitable principles. 
 5.3 Purchase Entirely for Own Account. The Shares to be received by such Investor hereunder will be

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

warranties contained in this Agreement.

“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

(a) “The securities represented hereby have not been registered with the Securities and Exchange Commission or the securities commission

5.9 Placement Agents. Such Investor hereby acknowledges and agrees that (a) each of the Placement Agents is acting solely as
placement agent in connection with the execution, delivery and performance of the Transaction Documents and is not acting as an underwriter or in any other capacity in connection therewith and is not and shall not be construed as a fiduciary for
such Investor, the Company or any other person or entity in connection with the execution, delivery and performance of the Transaction Documents, (b) no Placement Agent has made or will make any representation or warranty, whether express or
implied, of any kind or character, to such Investor or has provided any advice or recommendation to such Investor in connection with the execution, delivery and performance of the Transaction Documents, (c) no Placement Agent will have any
responsibility with respect to (i) any representations, warranties or agreements made by any person or entity under or in connection with the execution, delivery and performance of the Transaction Documents, or the execution, legality, validity

and (d) no Placement Agent will have any liability or obligation (including without limitation, for or with respect to any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements

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. 
 5.12 Short Sales and Confidentiality. 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 or of any other entity on the basis
of confidential information provided by the Company or a Placement Agent to such Investor transaction (including the existence and terms of this transaction and other non-public information), (the
“Confidential Information”) during the period commencing as of the time that such Investor was first contacted by the Company, a Placement Agent 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. Subject to Section 9.7, other than to other Persons party to this Agreement and to such Investor’s legal counsel, such Investor has
maintained and will continue to maintain the confidentiality of the Confidential Information, and such Investor agrees that it will not use any Confidential Information in violation of applicable securities laws.

Company as such term is understood under the rules promulgated pursuant to Section 13(d) of the 1934 Act.

address immediately below such Investor’s name on its signature page hereto. 
 5.17 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.

 (iii) By an
Investor (with respect to itself only) if any of the conditions set forth in Section 6.2 shall have become incapable of fulfillment, and shall not have been waived by the Investor;

 7.4 Removal of Legends. 

(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, provided that the Company has received from the Investor customary representations and other documentation reasonably acceptable to the Company in connection therewith. 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 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 (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 7.4, 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 customary representations and other documentation reasonably acceptable to the Company and the Transfer Agent in connection therewith,
deliver or cause to be delivered to such Investor a certificate representing such Shares 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 Depository Trust Company (“DTC”) 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. 
 (b) 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. 

7.5 Subsequent Equity Sales. 

(a) From the date hereof until sixty (60) days after the Closing Date, without the consent of the Required Investors, the Company shall
not (A) issue shares of Common Stock or Common Stock Equivalents or (B) file with the SEC a registration statement under the 1933 Act relating to any shares of Common Stock or Common Stock Equivalents, except pursuant to the terms of
agreements to which the Company is currently a party or as described in the Disclosure Schedule. Notwithstanding the foregoing, the provisions of this Section 7.5(a) shall not apply to (i) the issuance of the Shares hereunder,
(ii) the issuance of Common Stock or Common Stock Equivalents upon the conversion or exercise of any securities of the Company outstanding or issuable on the date hereof or outstanding or issuable pursuant to clause (iii) or
(vii) below, (iii) the issuance of any Common Stock or Common Stock Equivalents pursuant to any Company stock-based compensation plans, (iv) the filing of a registration statement on
Form S-8 under the 1933 Act to register the offer and sale of securities under any employee benefit or equity incentive plans of the Company, (v) the issuance of Common Stock pursuant to the Sales
Agreement, dated August 9, 2018, between the Company and Cowen and Company, LLC, as amended, at a price per share at or above $30.00 (the “Threshold Price Restriction”), subject to any adjustment for any Stock Event;
provided, however, that the Threshold Price Restriction shall no longer apply to this clause (v) after the Shares have been registered for resale pursuant to the Registration Rights Agreement, (vi) the filing of a registration
statement on Form S-3 under the 1933 Act to register the offer and sale of securities pursuant to the registration rights agreements disclosed in the SEC Filings or (vii) the issuance of any Common Stock
or Common Stock Equivalents in connection with a transaction described or as otherwise disclosed in the Disclosure Schedule. 

  
 17 













 (b) The Company shall not, and shall use its commercially reasonable efforts to ensure that
no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the 1933 Act) that will be integrated with the offer or sale of the Shares in a
manner that would require the registration under the 1933 Act of the sale of the Shares to the Investors, or that will be integrated with the offer or sale of the Shares for purposes of the rules and regulations of any trading market such that
it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction. 

7.6 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 initially publicly disclosed by the Company as provided in Section 9.7, such Investor will
maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Each Investor understands and acknowledges that the staff of 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. 

8. Survival and Indemnification. 

8.1 Survival. The representations, warranties, covenants and agreements contained in this Agreement shall survive the Closing of the
transactions contemplated by this Agreement for the applicable statute of limitations. 
 8.2 Indemnification. The Company agrees to
indemnify and hold harmless each Investor and its Affiliates, and their respective directors, officers, trustees, members, managers, employees, investment advisers and agents, from and against any and all losses, claims, damages, liabilities and
expenses (including without limitation reasonable and documented attorney fees and disbursements and other documented out-of-pocket expenses reasonably incurred in
connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, “Losses”) to which such Person may become subject as a result of any
breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under the Transaction Documents, and will reimburse any such Person for all such amounts as they are incurred by such Person solely to
the extent such amounts have been finally judicially determined not to have resulted from such Person’s fraud or willful misconduct. 

8.3 Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt
notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party;
provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person
unless (a) the indemnifying party has agreed in writing to pay such fees or expenses, (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in
the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying
party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided,
further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely
affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one
separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation or that includes any admission as to fault, culpability or failure to act on the part
of such indemnified party. No indemnified party will, except with the consent of the indemnifying party, consent to entry of any judgment or enter into any settlement.

 9. Miscellaneous. 

9.1 Successors and Assigns. This Agreement may not be assigned by a party hereto without the prior written consent of the Company or
each of the Investors, as applicable, provided, however, that an Investor may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring some or all of its Shares in a transaction complying
with applicable securities laws without the prior written consent of the Company or the other Investors, provided such assignee agrees in writing to be bound by the provisions hereof that apply to Investors. The provisions of this Agreement shall
inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Without limiting the generality of the foregoing, in the event that the Company is a party to a merger, consolidation, share exchange or
similar business combination transaction in which the Common Stock is converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have
assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Shares” shall be deemed to refer to the securities received by the Investors in connection with such
transaction. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective permitted successors and assigns any rights, remedies, obligations, or liabilities under or by reason
of this Agreement, except as expressly provided in this Agreement. 
 9.2 Counterparts; Faxes;
E-mail. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may
also be executed via facsimile or e-mail, which shall be deemed an original. 
 9.3 Titles and
Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. 

9.4 Notices. Unless otherwise provided, any notice required or permitted under this Agreement shall be given in writing and shall be
deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery, (ii) if given by facsimile or e-mail, then such notice
shall be deemed given upon receipt of confirmation of complete facsimile transmittal or confirmation of receipt of an e-mail transmission, (iii) if given by mail, then such notice shall be deemed given
upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an internationally recognized overnight air courier, then such
notice shall be deemed given one Business Day after delivery to such carrier. All notices shall be addressed to the party to be notified at the address as follows, or at such other address as such party may designate by ten days’ advance
written notice to the other party:

 If to the Investors: 

To the addresses set forth on the signature pages hereto. 

9.5 Expenses. Except as set forth elsewhere in the Transaction Documents, the parties hereto shall pay their own costs and expenses in
connection herewith regardless of whether the transactions contemplated hereby are consummated; it being understood that each of the Company and each Investor has relied on the advice of its own respective counsel. 

9.6 Amendments and Waivers. Prior to Closing, no amendment or waiver of any provision of this Agreement will be effective with respect
to any party unless made in writing and signed by a duly authorized representative of such party and consented to in writing by the Company and the Required Investors. Following the Closing, any term of this Agreement may be amended and the
observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Required Investors. 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. Any amendment or waiver effected in accordance with this paragraph shall be binding upon (i) prior to Closing, each Investor that signed such amendment or waiver and (ii) following the Closing, each holder of any Shares purchased
under this Agreement at the time outstanding, and in each case, each future holder of all such Shares and the Company. 
 9.7
Publicity. Except as set forth below, no public release or announcement concerning the transactions contemplated hereby shall be issued by the Investors without the prior consent of the Company (which consent shall not be unreasonably
withheld), 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 without prior notice to or consent from the Company. The Company shall not include the name of any Investor in any press release or public announcement (which, for the avoidance of doubt, shall not include any SEC Filing)
without the prior written consent of such Investor. By 8:30 a.m. (New York City time) on the Business Day immediately following the date this Agreement is executed, the Company shall issue one or more press releases (each, a “Press
Release”) disclosing all material terms of transactions contemplated by this Agreement and described in paragraphs 1 and 2 of the Disclosure Schedule. No later than 5:30 p.m. (New York City time) on the fourth Business Day following
the date this Agreement is executed, the Company will file a Current Report on Form 8-K (the “8-K Filing”) attaching the press releases described
in the foregoing sentence as well as copies of the Transaction Documents. In addition, the Company will make such other filings and notices in the manner and time required by the SEC or NYSE. The Company shall not, and shall cause each of its
officers, directors, employees and agents, not to, provide any Investor with any such material, nonpublic information regarding the Company from and after the filing of the Press Release without the express prior written consent of such Investor.

 9.8 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by
applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any provision
of law which renders any provision hereof prohibited or unenforceable in any respect. 
 9.9 Benefit of the Agreement. Each of the
Placement Agents is an intended third party beneficiary of the representations and warranties of each Investor set forth in Section 5 of this Agreement. 

  
 20 













 9.10 Entire Agreement. This Agreement, including the signature pages, Exhibits, and
the other Transaction Documents constitute the entire agreement among the parties hereof with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with
respect to the subject matter hereof and thereof. 
 9.11 Further Assurances. The parties shall execute and deliver all such further
instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained. 

9.12 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance
with, the internal laws of the State of New York without regard to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County
and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in
connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the
jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts
and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT
TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 9.13 Independent Nature of
Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of
the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase Shares pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein
or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the
Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in
connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Shares or enforcing its rights under the Transaction Documents. Each Investor shall be
entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined as an
additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Investors and not because it was
required or requested to do so by any Investor.
