brokers’ commissions (other than for persons engaged by any Buyer or its investment advisor) relating to or arising out of the transactions contemplated hereby in connection with the sale of the Securities. The Company shall pay, and hold each
Buyer harmless against, any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim. 

(h) No Integrated Offering. None of the Company, its Subsidiaries, any of their affiliates, and any Person acting on their behalf has,
directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of any of the Securities under the 1933 Act, whether through integration with prior
offerings or otherwise, or caused this offering of the Securities to require approval of stockholders of the Company for purposes of any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of
any exchange or automated quotation system on which any of the securities of the Company are listed or designated, but excluding stockholder consents required to authorize and issue the Securities or waive any anti-dilution provisions in connection
therewith. None of the Company, its Subsidiaries, their affiliates and any Person acting on their behalf will take any action or steps referred to in the preceding sentence that would require registration of any of the Securities under the 1933 Act

stockholders of the Company.

have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the

contemplated by this Agreement, including, without limitation, the Company’s issuance of the Securities and any Buyer’s ownership of the Securities. The

beneficial ownership of Common Stock or a change in control of the Company.

unaudited financial statements will be subject to normal adjustments which are not expected to have a Material Adverse Effect on the Company or any of its Subsidiaries. The Financial Statements do not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The forecasts and projections previously delivered to the

knowledge of the Company, is the landlord of any such lease in default except where any such default would not have a Material Adverse Effect.

Material Adverse Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface
water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes

 (i)
Each of the Company and its Subsidiaries has filed or caused to be filed in a timely manner (within any applicable extension periods) and in the appropriate jurisdictions all material returns, reports, information statements and other documentation
(including any additional or supporting materials) filed or maintained, or required to be filed or maintained, in connection with the calculation, determination, assessment or collection of any and all federal, state, local, foreign and other taxes,
levies, fees, imposts, duties, governmental fees and charges of whatever kind (including any interest, penalties or additions to the tax imposed in connection therewith or with respect thereto), including, without limitation, taxes imposed on, or

shall include amended returns required as a result of examination adjustments made by the IRS or other Governmental Authority responsible for the imposition of any Tax (collectively, the “Returns”) and such Returns are true, correct
and complete in all material respects. 
 (ii) Each of the Company and its Subsidiaries has paid all material Taxes and other assessments
due from and payable by the Company and its Subsidiaries on or prior to the date hereof on a timely basis except as to those set forth in Schedule 3(z)(ii). The charges, accruals, and reserves for Taxes with respect to the Company and its
Subsidiaries are adequate to cover Tax liabilities of the Company and its Subsidiaries accruing throughout the date thereof. Except as set forth in Schedule 3(z)(ii), each of the Company and its Subsidiaries has complied in all material
respects with all applicable Legal Requirements relating to the payment and withholding of Taxes (including withholding and reporting requirements under Sections 1441 through 1464, 3401 through 3406, and 6041 and 6049 of the Code and similar
provisions under any other applicable Legal Requirements) and, within the time and in the manner prescribed by law, has withheld from wages, fees and other payments and paid over to the proper governmental or regulatory authorities all amounts
required. Except as set forth in Schedule 3(z)(ii), neither the Company nor any of its Subsidiaries has received notice of assessment or proposed assessment of any Taxes claimed to be owed by it or any other Person on its behalf. Except as
set forth in Schedule 3(z)(ii), no Returns filed by or on behalf of the Company or any of its Subsidiaries with respect to Taxes are currently being audited or examined. Except as set forth in Schedule 3(z)(ii), neither the Company nor
any of its 

  
 25 

 
Subsidiaries has received notice of any such audit or examination. Except as set forth in Schedule 3(z)(ii), no issue has been raised by any taxing authority with respect to the Company or
any of its Subsidiaries in any audit or examination which, by application of similar principles, could reasonably be expected to result in a proposed material adjustment to the liability for Taxes for any period not so examined. 

(iii) Except as set forth in Schedule 3(z)(iii), no known Liens have been filed and no claims are being asserted by or against the
Company or any of its Subsidiaries with respect to any Taxes (other than Liens for Taxes not yet due and payable). Neither the Company nor any of its Subsidiaries has elected pursuant to the Code to be treated as an S corporation or any comparable
provision of local, state or foreign law, or has made any other elections pursuant to the Code (other than elections that relate solely to entity classification, methods of accounting, depreciation, or amortization) that would have a material effect
on the business, properties, prospects, or financial condition of the Company and its Subsidiaries, individually or in the aggregate. 

(iv) No claim has ever been made, or, to the knowledge of the Company, is threatened or pending, by any authority in a jurisdiction where the
Company or any of its Subsidiaries, respectively, does not file Returns that the Company or any of its Subsidiaries is or may be subject to taxation by that jurisdiction, and neither the Company nor any of its Subsidiaries has received any notice or
request for information from any such authority. Neither the Company nor any of its Subsidiaries has been a member of an affiliated group (as defined in Section 1504(a) of the Code) or filed or been included in a combined, consolidated or
unitary income tax return other than the affiliated group of which the Company is currently the common parent. Neither the Company nor any of its Subsidiaries is required to include in income any adjustment pursuant to Section 481(a) of the
Code by reason of a voluntary change in accounting methods initiated by the Company or any of its Subsidiaries, and no Governmental Authority has proposed an adjustment or change in accounting method. All transactions or methods of accounting that
could give rise to a substantial understatement of federal income tax as described in Section 6662(d)(2)(B)(i) of the Code have been adequately disclosed on the Company’s and its Subsidiaries’ federal income tax returns in accordance
with Section 6662(d)(2)(B) of the Code. Neither the Company nor any of its Subsidiaries is a party to any Tax sharing or Tax indemnity agreement or any other agreement of a similar nature that remains in effect. Neither the Company nor any of
its Subsidiaries has consented to any waiver of the statute of limitations for the assessment of any Taxes or has requested any extension of time for the payment of any Taxes. Neither the Company nor any of its Subsidiaries has ever held a material
beneficial interest in any other Person, other than those listed in Schedule 3(z)(iv). Neither the Company nor any of its Subsidiaries is obligated to make, nor as a result of any event connected with the transactions contemplated by this
Agreement will become obligated to make, any payment that would not be deductible under Section 280G of the Code. Neither the Company nor any Subsidiary of the Company is a “passive foreign investment company” within the meaning of
Section 1296 of the Code (a “PFIC”), and the Company does not anticipate that the Company or any additional foreign Subsidiary will become a PFIC in the foreseeable future. 

(aa) Internal Accounting and Disclosure Controls. The Company and each of its Subsidiaries maintain a system of internal accounting
controls appropriate for its size and privately held status and sufficient to provide reasonable assurance that (i) transactions are 

  
 26 

 
executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements that accurately
reflect the current status of the business of the Company and its Subsidiaries and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in accordance with management’s
general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken with respect to any difference.
During the twelve months prior to the date hereof neither the Company nor any of its Subsidiaries have received any notice or correspondence from any accountant relating to any potential material weakness in any part of the system of internal
accounting controls of the Company or any of its Subsidiaries. 
 (bb) Off Balance Sheet Arrangements. There is no transaction,
arrangement, or other relationship between the Company and an unconsolidated or other off balance sheet entity that is not disclosed by the Company in its Financial Statements or that otherwise would be reasonably likely to have a Material Adverse
Effect. 
 (cc) Investment Company Status. The Company is not, and upon consummation of the sale of the Securities will not be, an
“investment company,” a company controlled by an “investment company” or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company” as such terms are
defined in the Investment Company Act of 1940, as amended. 
 (dd) Illegal or Unauthorized Payments; Political Contributions Neither
the Company or any of its Subsidiaries nor, to the best of the Company’s knowledge (after reasonable inquiry of its officers and directors), any of the officers, directors, employees, agents or other representatives of the Company or any of its
Subsidiaries or any other business entity or enterprise with which the Company or any Subsidiary is or has been affiliated or associated, has, directly or indirectly, made or authorized any payment, contribution or gift of money, property, or
services, whether or not in contravention of applicable law, (a) as a kickback or bribe to any Person or (b) to any political organization, or the holder of or any aspirant to any elective or appointive public office except for personal
political contributions not involving the direct or indirect use of funds of the Company or any of its Subsidiaries. 
 (ee) Transfer
Taxes. On the Closing Date, all stock transfer or other taxes (other than income or similar taxes) which are required to be paid in connection with the sale and transfer of the Securities to be sold to each Buyer hereunder will be, or will have
been, fully paid or provided for by the Company, and all laws imposing such taxes will be or will have been complied with. 
 (ff) Books
and Records. The books of account, ledgers, order books, records and documents of the Company and its Subsidiaries accurately and completely reflect all information relating to the respective businesses of the Company and its Subsidiaries, the
nature, acquisition, maintenance, location and collection of each of their respective assets, and the nature of all transactions giving rise to material obligations or accounts receivable of the Company or its Subsidiaries, as the case may be,
except where the failure to so reflect such information would not have a Material Adverse Effect. The minute books of the Company and its Subsidiaries 

  
 27 

 
contain accurate records of all meetings and accurately reflect all other actions taken by the stockholders, boards of directors and all committees of the boards of directors, and other governing
Persons of the Company and its Subsidiaries, respectively. 
 (gg) Money Laundering. The Company and its Subsidiaries are in
compliance with, and have not previously violated, the USA PATRIOT ACT of 2001 (the “PATRIOT Act”) and all other applicable U.S. and non-U.S. anti-money laundering laws and regulations, including, but not limited to, the laws,
regulations and Executive Orders and sanctions programs administered by the U.S. Office of Foreign Assets Control (“OFAC”), including, but not limited, to (i) Executive Order 13224 of September 23, 2001 entitled,
“Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism” (66 Fed. Reg. 49079 (2001)); and (ii) any regulations contained in 31 CFR, Subtitle B, Chapter V (collectively, the
“Anti-Money Laundering/OFAC Laws”). 
 (hh) Acknowledgement Regarding Buyers’ Trading Activity. It is
understood and acknowledged by the Company (a) (i) that except as set forth in Section 4(r), none of the Buyers have been asked by the Company or its Subsidiaries to agree, nor has any Buyer agreed with the Company or its
Subsidiaries, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Securities for any specified term; and (ii) that
each Buyer shall not be deemed to have any affiliation with or control over any arm’s length counter party in any “derivative” transaction. The Company further understands and acknowledges that one or more Buyers may engage in hedging
and/or trading activities at various times during the period that the Securities are outstanding, including, without limitation, during the periods that the value of the Conversion Shares and/or the Warrant Shares are being determined and
(b) such hedging and/or trading activities, if any, can reduce the value of the existing stockholders’ equity interest in the Company both at and after the time the hedging and/or trading activities are being conducted. The Company
acknowledges that such aforementioned hedging and/or trading activities do not constitute a breach of any of the Transaction Documents. 

(ii) U.S. Real Property Holding Corporation. The Company is not, has never been, and so long as any Securities remain outstanding,
shall not become, a U.S. real property holding corporation within the meaning of Section 897 of the Internal Revenue Code of 1986, as amended, and the Company shall so certify upon any Buyer’s request. 

(jj) Bank Holding Company Act. Neither the Company nor any of its Subsidiaries is subject to the Bank Holding Company Act of 1956, as
amended (the “BHCA”) and to regulation by the Board of Governors of the Federal Reserve System (the “Federal Reserve”). Neither the Company nor any of its Subsidiaries or affiliates owns or controls, directly or
indirectly, five percent (5%) or more of the outstanding shares of any class of voting securities or twenty-five percent (25%) or more of the total equity of a bank or any entity that is subject to the BHCA and to regulation by the Federal
Reserve. Neither the Company nor any of its Subsidiaries or affiliates exercises a controlling influence over the management or policies of a bank or any entity that is subject to the BHCA and to regulation by the Federal Reserve. 

(kk) Shell Company Status. The Company is not, and has never been, an issuer identified in Rule 144(i)(1) of the 1933 Act. 

  
 28 

 (ll) No Disqualification Events. With respect to Securities to be offered and sold
hereunder in reliance on Rule 506 under the 1933 Act (“Regulation D Securities”), none of the Company, any of its predecessors, any affiliated issuer, any director, executive officer, other officer of the Company participating in
the offering hereunder, any beneficial owner of 20% or more of the Company’s outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under the 1933 Act) connected with
the Company in any capacity at the time of sale (each, an “Issuer Covered Person” and, together, “Issuer Covered Persons”) is subject to any Disqualification Event, except for a Disqualification Event covered by
Rule 506(d)(2) or (d)(3). The Company has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification Event. The Company has complied, to the extent applicable, with its disclosure obligations under
Rule 506(e), and has furnished to the Buyers a copy of any disclosures provided thereunder. 
 (mm) Other Covered Persons. The
Company is not aware of any Person (other than any Issuer Covered Person) that has been or will be paid (directly or indirectly) remuneration for solicitation of Buyers or potential purchasers in connection with the sale of any Regulation D
Securities. 
 (nn) Disclosure. The Company understands and confirms that each of the Buyers will rely on the foregoing
representations in effecting transactions in securities of the Company. No statement made by the Company in this Agreement, any other Transaction Document or the exhibits and schedules attached hereto or in any certificate or schedule furnished or
to be furnished by or on behalf of the Company to the Investors or any of their representatives in connection with the transactions contemplated hereby contains any untrue statement of a material fact or omits to state a material fact necessary in
order to make the statements contained herein or therein not misleading. The due diligence materials previously provided by or on behalf of the Company to each Buyer (the “Due Diligence Materials”), have been prepared in a good
faith effort by the Company to describe the Company’s present and proposed products, and projected growth and the Company and do not contain any untrue statement of a material fact or omit to state a material fact necessary to make the
statements therein not misleading, except that with respect to assumptions, projections and expressions of opinion or predictions contained in the Due Diligence Materials, the Company represents only that such assumptions, projections, expressions
of opinion and predictions were made in good faith and that the Company believes there is a reasonable basis therefor. The Due Diligence Materials contain all material agreements of the Company and its Subsidiaries and no material agreements of the
Company or its Subsidiaries exist other than those provided in the Due Diligence Materials. The Company acknowledges and agrees that no Investor participated in the preparation of, or has any responsibility for, the content of any Due Diligence
Materials.

effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document, including, without limitation,
Section 2(g) hereof; provided that an Investor and its pledgee shall be required to comply with the provisions of Section 2(g) hereof in order to effect a sale, transfer or assignment of Securities to such pledgee. The Company hereby
agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by an Investor. 

(h) Disclosure of Transactions and Other Material Information. From and after the earliest of the initial filing by the Company of a
registration statement, a filing on Form 10 or a Current Report on Form 8-K with respect to any capital stock of the Company with the SEC (the “Initial Filing”) on or prior to the Public Company Date, no Buyer shall be in possession
of any material, nonpublic information received from the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, that is not disclosed in the Initial Filing. In addition, effective upon the filing of the
Initial Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors,
affiliates, employees or agents, on the one hand, and any of the Buyers or any of their affiliates, on the other hand, shall terminate. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers,
directors, employees and agents, not to, provide any Buyer with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the Initial Filing with the SEC without the express prior written consent of such
Buyer. If a Buyer has, or believes it has, received any such material, nonpublic information regarding the Company or any of its 

  
 31 

 
Subsidiaries, it may provide the Company with written notice thereof. The Company shall, within two (2) Trading Days of receipt of such notice, make public disclosure of such material,
nonpublic information. In the event of a breach of the foregoing covenant by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the
Transaction Documents, a Buyer shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, its Subsidiaries,
or any of its or their respective officers, directors, employees or agents. No Buyer shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents for any such
disclosure. To the extent that the Company delivers any material, non-public information to a Buyer without such Buyer’s consent, the Company hereby covenants and agrees that such Buyer shall not have any duty of confidentiality with respect
to, or a duty not to trade on the basis of, such material, non-public information. Subject to the foregoing, neither the Company, its Subsidiaries nor any Buyer shall issue any press releases or any other public statements with respect to the
transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior approval of any Buyer, to make any press release or other public disclosure with respect to such transactions as is required by applicable law
and regulations, provided that each Buyer shall be consulted by the Company in connection with any such press release or other public disclosure prior to its release. Without the prior written consent of any applicable Buyer, neither the Company nor
any of its Subsidiaries or affiliates shall disclose the name of such Buyer in any filing, announcement, release or otherwise. Notwithstanding the foregoing, in no event will the Company have an obligation to disclose any information which a Buyer
receives from a member of the Company’s Board of Directors that is an affiliate of such Buyer. 
 (i) Additional Preferred Shares;
Variable Securities. So long as any Buyer beneficially owns any Securities, the Company will not issue any Preferred Shares other than to the Buyers as contemplated hereby and the Company shall not issue any other securities that would cause a
breach or default under the Certificate of Designations or the Warrants. For so long as any Securities remain outstanding, the Company shall not, in any manner, issue or sell any rights, warrants or options to subscribe for or purchase Common Stock
or directly or indirectly convertible into or exchangeable or exercisable for Common Stock at a price which varies or may vary with the market price of the Common Stock, including by way of one or more reset(s) to any fixed price unless the
conversion, exchange or exercise price of any such security cannot be less than the greater of (x) the then applicable Conversion Price (as defined in the Certificate of Designations) with respect to the Common Stock into which any Preferred
Share is convertible and (y) the then applicable Exercise Price (as defined in the Initial Warrants) with respect to the Common Stock into which any Initial Warrant is exercisable. 

(j) Corporate Existence. So long as any Buyer beneficially owns any Securities, the Company shall (i) maintain its corporate
existence and (ii) not be party to any Fundamental Transaction (as defined in the Certificate of Designations) unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Certificate of
Designations and the Warrants. 
 (k) Reservation of Shares. The Company shall take all action necessary to at all times have
authorized, and reserved for the purpose of issuance, (A) no less than 130% of the 

  
 32 

 
maximum number of shares of Common Stock issuable (i) upon conversion of the maximum number of Preferred Shares issued and issuable pursuant to the Series C-1 Warrants (assuming for purposes
hereof, that the Preferred Shares are convertible at the Conversion Price and without taking into account any limitations on the conversion of the Preferred Shares set forth in the Certificate of Designations) and (ii) upon exercise of the
Initial Warrants (without taking into account any limitations on the exercise of the Initial Warrants set forth in the Initial Warrants), and (B) not less than the maximum number of Series C-1 Warrant Shares issuable upon exercise of the Series
C-1 Warrants, in each case, determined as if issued as of the trading day immediately preceding the applicable date of determination (the “Required Reserved Amount”). If at any time the number of shares of Common Stock authorized
and reserved for issuance is not sufficient to meet the Required Reserved Amount, the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including, without limitation, calling a special
meeting of stockholders to authorize additional shares to meet the Company’s obligations under Section 3(c), in the case of an insufficient number of authorized shares, obtain stockholder approval of an increase in such authorized number
of shares, and voting the any treasury shares of the Company in favor of an increase in the authorized shares of the Company to ensure that the number of authorized shares is sufficient to meet the Required Reserved Amount. In connection with any
such vote, each Buyer hereby agrees that it shall, if requested by the Company, vote all shares of capital stock held by such Buyer in favor of any such increase in the authorized number of shares. 

(l) Conduct of Business. The business of the Company and its Subsidiaries shall not be conducted in violation of any law, ordinance or
regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect. The Company and its Subsidiaries shall at all times be in compliance with the Foreign
Corrupt Practices Act; the PATRIOT Act, and all other applicable U.S. and non-U.S. anti-money laundering laws and regulations; and the laws, regulations and Executive Orders and sanctions programs administered by the OFAC, including, without
limitation, the “Anti-Money Laundering/OFAC Laws”. 
 (m) Public Information. At any time during the period commencing on
the six (6) month anniversary of the Public Company Date and ending at such time that all of the Securities, if (A) a registration statement is not available for the resale of all of the Securities, may be sold without restriction or
limitation pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1), if the Company shall (i) fail for any reason to satisfy the requirements of Rule 144(c)(1), including, without limitation, the failure to
satisfy the current public information requirement under Rule 144(c) or (ii) if the Company has ever been an issuer described in Rule 144(i)(1)(i) or becomes such an issuer in the future, and the Company shall fail to satisfy any condition set
forth in Rule 144(i)(2) (other than during the one-year period immediately following the consummation of the Reverse Merger (as defined in the Certificate of Designations) if the Company becomes an issuer described in Rule 144(i)(1)(i) solely as a
result of the Successor Entity in the Reverse Merger (as such terms are defined in the Certificate of Designations) being an issuer described in Rule 144(i)(1)(i) at the time of the consummation of the Reverse Merger, and (B) any such failure
continues for more than two (2) Trading Days (a “Public Information Failure”) then, as partial relief for the damages to any holder of Securities by reason of any such delay in or reduction of its ability to sell the Securities
(which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay 

  
 33 

 
to each such holder an amount in cash equal to two percent (2.0%) of the aggregate Purchase Price of such holder’s Securities on the day of a Public Information Failure and on every
thirtieth day (pro-rated for periods totaling less than thirty days) thereafter until the earlier of (i) the date such Public Information Failure is cured and (ii) such time that such public information is no longer required pursuant to
Rule 144. The payments to which a holder shall be entitled pursuant to this Section 4(m) are referred to herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of
(I) the last day of the calendar month during which such Public Information Failure Payments are incurred and (II) the third Business Day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event
the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. 

(n) Additional Issuances of Securities. 

(i) For purposes of this Section 4(n), the following definitions shall apply. 

(1) “Common Stock Equivalents” means, collectively, Options and Convertible Securities. 

(2) “Convertible Securities” means any stock or securities (other than Options) convertible into or exercisable or
exchangeable for shares of Common Stock. 
 (3) “Excluded Securities” means any capital stock issued or issuable:
(i) upon conversion of the Preferred Shares; (ii) exercise of the Warrants; provided, that the terms of such Warrants are not amended or modified after the date hereof; (iii) upon exercise or conversion of Convertible Securities
outstanding as of the date hereof; provided, that the terms of such Convertible Securities are not amended or modified after the date hereof; (iv) as a dividend, stock split or as a result of any other adjustment pursuant to the Certificate of
Designation, including any anti-dilution adjustment thereunder, and (v) pursuant to any employee benefit plan which has been approved by the Board of Directors of the Company pursuant to which the Company’s securities may be issued to any
employee, officer or director for services provided to the Company. 
 (4) “Options” means any rights, warrants or options
to subscribe for or purchase Common Stock or Convertible Securities. 
 (5) “Subsequent Placement” means any direct or
indirect offer, sale, grant of any option to purchase, or other disposition of (or announcement of any offer, sale, grant or any option to purchase or other disposition of) any of the Company’s or its Subsidiaries’ equity, debt or equity
equivalent securities, including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for Common Stock or
Common Stock Equivalents. 

  
 34 

 (ii) From the Closing Date and for so long any of the Preferred Shares remain outstanding, the
Company will not, directly or indirectly, effect any Subsequent Placement unless the Company shall have first complied with this Section 4(n)(ii). 

(1) The Company shall deliver to each holder of Preferred Shares (each a “Preferred Holder”, and collectively, the
“Preferred Holders”) an irrevocable written notice (the “Offer Notice”) of any proposed or intended issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered
Securities”) in a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or
amount of the Offered Securities to be issued, sold or exchanged, (y) identify the persons or entities (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z) offer to issue and sell to
or exchange with each Preferred Holder its pro rata portion (based on such Buyer’s pro rata portion of the aggregate stated value of Initial Preferred Shares issued on the Closing Date) of at least fifty-five percent (55%) of the Offered
Securities (the “Basic Amount”). With respect to each Preferred Holder that elects to purchase its Basic Amount, such Preferred Holder may also indicate it will purchase or acquire any additional portion of the Offered Securities
attributable to the Basic Amounts of other Preferred Holders should the other Preferred Holders subscribe for less than their Basic Amounts (the “Undersubscription Amount”), which process shall be repeated until the Preferred
Holders shall have an opportunity to subscribe for any remaining Undersubscription Amount. 
 (2) To accept an Offer, in whole or in part,
such Preferred Holder must deliver a written notice to the Company prior to the end of the tenth (10th) Business Day after such Preferred Holder’s receipt of the Offer Notice (the
“Offer Period”), setting forth the portion of such Preferred Holder’s Basic Amount that such Preferred Holder elects to purchase and, if such Preferred Holder shall elect to purchase all of its Basic Amount, the
Undersubscription Amount, if any, that such Preferred Holder elects to purchase (in either case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Preferred Holders are less than the total of all of the Basic
Amounts, then each Preferred Holder who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for;
provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”),
each Preferred Holder who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of such Preferred Holder bears to the total Basic Amounts of all
Preferred Holders that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent its deems reasonably necessary. Notwithstanding anything to the contrary contained herein, if the Company desires to modify or
amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to the Preferred Holders a new Offer Notice and the Offer Period shall expire on the tenth (10th) Business Day after such Preferred
Holder’s receipt of such new Offer Notice. 
 (3) The Company shall have twenty (20) Business Days from the expiration of the
Offer Period above to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Preferred 

  
 35 

 
Holders (the “Refused Securities”) pursuant to a definitive agreement (the “Subsequent Placement Agreement”) but only to the offerees described in the Offer
Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to the Company than those set forth
in the Offer Notice and (ii) to publicly announce (a) the execution of such Subsequent Placement Agreement, and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or
(y) the termination of such Subsequent Placement Agreement, which, from and after the Public Company Date, shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated
therein filed as exhibits thereto. 
 (4) In the event the Company shall propose to sell less than all the Refused Securities (any such
sale to be in the manner and on the terms specified in Section 4(n)(ii)(3) above), then each Preferred Holder may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of
Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that such Preferred Holder elected to purchase pursuant to Section 4(n)(ii)(2) above multiplied by a fraction, (i) the numerator of which
shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Preferred Holders pursuant to Section 4(n)(ii)(3) above prior to such reduction)
and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Preferred Holder so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company
may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Preferred Holders in accordance with Section 4(n)(ii)(1) above. 

(5) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Preferred Holders shall acquire
from the Company, and the Company shall issue to the Preferred Holders, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 4(n)(ii)(3) above if the Preferred Holders have so
elected, upon the terms and conditions specified in the Offer. The purchase by the Preferred Holders of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Preferred Holders of a purchase
agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Preferred Holders and their respective counsel. 

(6) Any Offered Securities not acquired by the Preferred Holders or other persons in accordance with Section 4(n)(ii)(3) above may not
be issued, sold or exchanged until they are again offered to the Preferred Holders under the procedures specified in this Agreement. 
 (7)
The Company and the Preferred Holders agree that if any Preferred Holder elects to participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the
“Subsequent Placement Documents”) shall include any term or provisions whereby any Preferred Holder shall be required to agree to any restrictions in trading as to any securities of the Company owned by such Preferred Holder prior
to such Subsequent Placement, other than restrictions on transfer imposed under federal and state securities laws. 

  
 36 

 (8) Notwithstanding anything to the contrary in this Section 4(n) and unless otherwise
agreed to by the Preferred Holders, the Company shall either confirm in writing to the Preferred Holders that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered
Securities, in either case in such a manner such that the Preferred Holders will not be in possession of material non-public information, by the fifteenth (15th) Business Day following
delivery of the Offer Notice. If by the fifteenth (15th) Business Day following delivery of the Offer Notice no public disclosure regarding a transaction with respect to the Offered
Securities has been made, and no notice regarding the abandonment of such transaction has been received by the Preferred Holders, such transaction shall be deemed to have been abandoned and the Preferred Holders shall not be deemed to be in
possession of any material, non-public information with respect to the Company. Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide each Preferred Holder with another Offer Notice
and each Preferred Holder will again have the right of participation set forth in this Section 4(n)(ii). From and after the Public Company Date, the Company shall not be permitted to deliver more than one such Offer Notice to the Buyers in any
60 day period. 
 (iii) The restrictions contained in subsection (ii) of this Section 4(n) shall not apply in connection with the
issuance of any Excluded Securities. 
 (o) Taxes. The Company will pay, and save and hold the Buyers harmless from any and all
liabilities (including interest and penalties) with respect to, or resulting from any delay or failure in paying, stamp and other taxes (other than income taxes), if any, which may be payable or determined to be payable on the execution and delivery
or acquisition of the Preferred Shares, Warrants, Conversion Shares or Warrant Shares. 
 (p) D&O Insurance. The Company shall
obtain such director’s and officer’s insurance in such form, with such carrier and in such amounts as reasonably acceptable to the holders of a majority of the Preferred Shares (the “D&O Insurance”) within thirty
(30) days of the Closing Date. Thereafter, for so long as any Preferred Shares remain outstanding, the Company shall maintain the D&O Insurance. In the event the Company merges with another entity and is not the surviving corporation, or
transfers all or substantially all of its assets to any Person or any other similar Fundamental Transaction occurs, the Company shall require, prior to the consummation of such transaction, that such successor entity deliver a written agreement, in
form and substance reasonably satisfactory to the holders of a majority of Preferred Shares, assuming the Company’s obligations herein to maintain such D&O insurance with respect to former directors of the Company appointed by the holders
of Preferred Shares (the “Preferred Directors”) and to indemnify such Preferred Directors to the fullest extent permitted by Delaware law. 

(q) Books and Records. The Company will keep proper books of record and account, in which full and correct entries shall be made of all
financial transactions and the assets and business of the Company and its Subsidiaries in accordance with GAAP. 

  
 37 

 (r) Lock-Up. The Company shall not amend, waive or terminate any provision of any of the
Lock-Up Agreements except to extend the term of the lock-up period and shall enforce the provisions of each Lock-Up Agreement in accordance with its terms. If any party to a Lock-Up Agreement breaches any provision of a Lock-Up Agreement, the
Company shall promptly use its best efforts to seek specific performance of the terms of such Lock-Up Agreement. If at any time prior to the one year anniversary of the Public Company Date, any Person is, or is contemplated to become, a stockholder
or security holder of the Company that is not a party to a Lock-Up Agreement, the Company shall, and shall cause such Person to, enter into a Lock-Up Agreement prior to issuing any shares of Common Stock or Common Stock Equivalents to such Person
and prior to allowing such Person to become a stockholder or security holder of the Company. 
 (s) Proprietary Information and
Inventions Agreements. The Company shall not amend, waive or terminate any provision of any of the Proprietary Information and Inventions Agreements and shall enforce the provisions of each Proprietary Information and Inventions Agreements in
accordance with its terms. If any party to a Proprietary Information and Inventions Agreement breaches any provision of a Proprietary Information and Inventions Agreement, the Company shall promptly use its best efforts to seek specific performance
of the terms of such Proprietary Information and Inventions Agreement. 
 (t) Going Public. On or before the three (3) month
anniversary of the Closing Date, the Company shall either (A) cause a Form 10 registering the Company’s Common Stock under the 1934 to be declared effective by the SEC or (B) enter into definitive documentation on terms and conditions
acceptable to the Required Holders providing for the consummation of the Reverse Merger (as defined in the Certificate of Designations) in which a Successor Entity (as defined in the Certificate of Designations) that is a publicly traded corporation
whose stock is quoted or listed for trading on an Eligible Market (as defined in the Certificate of Designations) assumes the Initial Warrants and the Certificate of Designations such that, inter alia, the Initial Warrants shall be
exercisable into, and the shares of Series C Preferred Stock, including the shares of Series C-1 Preferred Stock issuable upon exercise of the Series C-1 Warrants, shall be convertible into, the publicly traded common stock of such Successor Entity.
Notwithstanding the foregoing, if the Company is proceeding in good faith towards the effectiveness of a Form 10 or a Reverse Merger and has demonstrated tangible steps to that effect reasonably acceptable to the Required Holders, the three month
deadline set forth above shall be extended to four months following the Closing Date. 
 (u) Notice of Disqualification Events. The
Company will notify the Buyers in writing, prior to the Closing Date and the Additional Closing Date of (i) any Disqualification Event relating to any Issuer Covered Person and (ii) any event that would, with the passage of time, become a
Disqualification Event relating to any Issuer Covered Person. 
 (v) Stock, Option and Equity Plans. From and after the Closing until
the first anniversary of the Public Company Date, neither the Company nor any Subsidiary shall, without the prior written consent of the Required Holders, (i) amend or modify any terms or conditions of the Company’s 2014 Employee, Director
and Consultant Equity Incentive Plan (the “Incentive Plan”), (ii) grant any stock, options or equity based incentives to any employees, members of management, directors or advisors of the Company or its Subsidiaries, other than

  
 38 

 
pursuant to the Incentive Plan, including, without limitation, as provided in Schedule I thereto or (ii) create or implement any stock, option or other equity incentive plan, other than the
Incentive Plan. 
 (w) 2013 Audited Financial Statements. No later than thirty (30) calendar days after the Closing Date, the
Company shall cause (i) the 2013 Unaudited Financial Statements to be audited by a reputable independent accounting firm reasonably acceptable to the Required Holders (as audited, the “2013 Audited Financial Statements”), and
(ii) the 2013 Audited Financial Statements to be delivered to each Buyer. 
 (x) Sufficient Cash. While any Series C-1 Preferred
Stock, Series C-1 Warrants or Series C-2 Preferred Stock remain outstanding, the Company shall maintain cash sufficient to cover any and all amounts budgeted in the Approval Annual Budget (as defined below) for (i) legal costs relating to the
proposed Reverse Merger or relating to the filing and effectiveness of the Form 10 registering the Company’s Common Stock under the 1934, as applicable, (ii) expenses relating to financial statement audits and reviews and
(iii) investor relations expenses; provided, however, that prior to the Subsequent Capital Raise, the Company shall only be required to maintain cash sufficient to cover at least half of all such amounts. 

(y) Post-Closing Deliveries. No later than fifteen (15) days after the Closing Date, the Company shall cause each of Maria
Alexander, Sam Danishefsky, Xiaohang Wu, and George Constantine to deliver to each Buyer an executed Lock-Up Agreement. Each Buyer acknowledges and agrees that the failure of such Persons to execute and deliver the documents described in the
immediately preceding sentence on or prior to the Closing Date shall not constitute a breach of any Transaction Documents or result in the failure of any condition thereunder to be met. 

(z) Closing Documents. On or prior to thirty (30) calendar days after the Closing Date, the Company agrees to deliver, or cause to
be delivered, to each Buyer and Schulte Roth & Zabel LLP a complete closing set of the executed Transaction Documents, Securities and any other documents required to be delivered to any party pursuant to Section 7 hereof or otherwise

  

	 	5.	REGISTER. 

 The Company shall maintain at its principal executive offices (or such other
office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Preferred Shares in which the Company shall record the name and address of the Person in whose name the Preferred Shares have been issued
(including the name and address of each transferee), the number of Preferred Shares held by such Person and the number of Conversion Shares issuable upon conversion of the Preferred Shares held by such Person. The Company shall keep the register

 (xx) The Company shall have implemented the Incentive Plan in form and substance reasonably
acceptable to the Required Holders. 
 (xxi) The Company shall have delivered to such Buyer such other documents relating to the
transactions contemplated by this Agreement as such Buyer or its counsel may reasonably request. 
  

	 	8.	TERMINATION.  

 In the event that the Closing shall not have occurred with respect to a
Buyer on or before five (5) Business Days from the date hereof due to the Company’s or such Buyer’s failure to satisfy the conditions set forth in Sections 6 and 7 above (and the nonbreaching party’s failure to waive such
unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this Agreement with respect to such breaching party at the close of business on such date by delivering a written notice to that effect to each other party to this
Agreement and without liability of any party to any other party; provided, however, that if this Agreement is terminated pursuant to this Section 8, the Company shall remain obligated to reimburse Hudson Bay or its designee(s), as applicable,
for the expenses described in Section 4(f) above. 
  

	 	9.	MISCELLANEOUS. 

 (a) Governing Law; Jurisdiction; Jury Trial. All questions
concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the
State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts
sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert
in any suit, action or proceeding, 

  
 42 

 
any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action
or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it
under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY. 

 (b) Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and
the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile signature shall be considered due execution and shall be binding upon the signatory thereto
with the same force and effect as if the signature were an original, not a facsimile signature. 
 (c) Headings. The headings of this
Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement. 
 (d)
Severability. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable
shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this
Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not
substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to
replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). 

(e) Entire Agreement; Amendments. This Agreement and the other Transaction Documents supersede all other prior oral or written
agreements between the Buyers, the Company, their affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement, the other Transaction Documents and the instruments referenced herein and therein
contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation, warranty, covenant or
undertaking with respect to such matters. Provisions of this Agreement may be amended and the observance thereof 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 holders of at least a 

  
 43 

 
majority of the Preferred Shares outstanding as of the applicable date of determination, which shall include Hudson Bay as long as Hudson Bay (or any of its Affiliates) owns any Preferred Shares
or has the right to purchase any Preferred Shares hereunder (the “Required Holders”); provided that any such amendment or waiver that complies with the foregoing but that disproportionately, materially and adversely affects the
rights and obligations of any Buyer relative to the comparable rights and obligations of the other Buyers shall require the prior written consent of such adversely affected Buyer. Any amendment or waiver effected in accordance with this
Section 9(e) shall be binding upon each Buyer and holder of Securities and the Company. No such amendment shall be effective to the extent that it applies to less than all of the Buyers or holders of Securities. No consideration shall be
offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration (other than the reimbursement of legal fees) also is offered to all of the parties to
the Transaction Documents, holders of Preferred Shares or holders of Warrants, as the case may be. The Company has not, directly or indirectly, made any agreements with any Buyers relating to the terms or conditions of the transactions contemplated
by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the foregoing, the Company confirms that, except as set forth in this Agreement, no Buyer has made any commitment or promise or has any other obligation
to provide any financing to the Company or otherwise. 
 (f) Notices. Any notices, consents, waivers or other communications required
or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of
transmission is mechanically or electronically generated and kept on file by the sending party) or by electronic mail; or (iii) one (1) Business Day after deposit with an overnight courier service, in each case properly addressed to the

service shall be rebuttable evidence of personal service, receipt by facsimile or receipt from an overnight courier service in accordance with clause (i), (ii) or (iii) above, respectively. 

(g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective
successors and assigns, including any purchasers of the Preferred Shares or the Warrants. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Required Holders, including by way
of a Fundamental Transaction (unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Certificate of Designations and the Warrants). A Buyer may assign some or all of its rights
hereunder without the consent of the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights. 

(h) No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted
successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that each Indemnitee shall have the right to enforce the obligations of the Company with respect to Section 9(k). 

(i) Survival. Unless this Agreement is terminated under Section 8, the representations and warranties of the Company and the
Buyers contained in Sections 2 and 3 and the agreements and covenants set forth in Sections 4, 5 and 9 shall survive the Closing and the delivery, conversion and/or exercise of the Securities, as applicable. Each Buyer shall be responsible only for
its own representations, warranties, agreements and covenants hereunder. 

  
 45 

 (j) Further Assurances. Each party shall do and perform, or cause to be done and
performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of
this Agreement and the consummation of the transactions contemplated hereby. 
 (k) Indemnification. 

(i) In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in
addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Buyer and each other holder of the Securities and all of their stockholders, partners,
members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this
Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of
whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a
result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby,
(b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby or (c) any cause of action, suit or claim brought
or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery, performance or enforcement of the Transaction
Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities,
(iii) any disclosure made by such Buyer pursuant to Section 4(h), or (iv) the status of such Buyer or holder of the Securities as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents. To
the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable
law. 
 (ii) Promptly after receipt by an Indemnitee under this Section 9(k) of notice of the commencement of any action or proceeding
(including any governmental action or proceeding) involving an Indemnified Liability, such Indemnitee shall, if a claim for indemnification in respect thereof is to be made against any indemnifying party under this Section 9(k), deliver to the
indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to
assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel with the fees and expenses of not more than
one counsel for such Indemnitee to be 

  
 46 

 
paid by the indemnifying party, if, in the reasonable opinion of the Indemnitee, the representation by such counsel of the Indemnitee and the indemnifying party would be inappropriate due to
actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceeding. Legal counsel referred to in the immediately preceding sentence shall be selected by the Investors holding at least a
majority of the Purchased Shares. The Indemnitee shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Indemnified Liabilities by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnitee that relates to such action or Indemnified Liabilities. The indemnifying party shall keep the Indemnitee fully apprised at all times as to the status of the defense or any
settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party shall not
unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld conditioned or delayed, consent to entry of any judgment or
enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a release from all liability in respect to such Indemnified Liabilities or
litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has
been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnitee under this Section 9(k),
except to the extent that the indemnifying party is prejudiced in its ability to defend such action. 
 (iii) The indemnification required
by this Section 9(k) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Liabilities are incurred. 

(iv) The indemnity agreements contained herein shall be in addition to (x) any cause of action or similar right of the Indemnitee
against the indemnifying party or others, and (y) any liabilities the indemnifying party may be subject to pursuant to the law. 
 (l)
No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 

(m) Remedies. Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents
and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under any provision of this Agreement shall
be entitled to enforce such rights specifically to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company recognizes that in the event that it fails to
perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled to seek temporary and
permanent injunctive relief in any such case without the necessity of proving actual damages. 

  
 47 

 (n) Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in
(and without limiting any similar provisions of) the Transaction Documents, whenever any Buyer exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the
periods therein provided, then such Buyer may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and
rights. 
 (o) Payment Set Aside. To the extent that the Company makes a payment or payments to the Buyers hereunder or pursuant to
any of the other Transaction Documents or the Buyers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to
be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy
law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such enforcement or setoff had not occurred. 
 (p) Reproduction of Documents. This Agreement and
all documents relating thereto, including, without limitation, (a) consents, waivers and modifications which may hereafter be executed, (b) documents received by the Buyers on the Closing Date (except for certificates evidencing the
Preferred Shares themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to the Buyers, may be reproduced by any Buyer by any photographic, photostatic, microfilm, micro-card, miniature photographic or other similar process and any Buyer may destroy any original document so reproduced. All parties hereto agree and stipulate that any such reproduction shall be admissible in
evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by a Buyer in the regular course of business) and that any enlargement, facsimile
or further reproduction of such reproduction shall likewise be admissible in evidence. 
 (q) Independent Nature of Buyers’
Obligations and Rights. The obligations of each Buyer under any Transaction Document are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any
other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as, and the Company acknowledges that
the Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in any way acting in concert or as a group, and the Company shall not assert any such claim with
respect to such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Buyers are not acting in concert or as a group with respect to such obligations or the transactions contemplated by the

  
 48 

 
Transaction Documents. The Company acknowledges and each Buyer confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own
counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for
any other Buyer to be joined as an additional party in any proceeding for such purpose.

1. Definitions; References; Continuation of Purchase Agreement. Unless otherwise specified herein, each capitalized term used herein
that is defined in the Purchase Agreement shall have the meaning assigned to such term in the Purchase Agreement. Each reference to “hereof,” “hereto,” “hereunder,” “herein” and “hereby” and each
other similar reference, and each reference to “this Agreement”, the “Securities Purchase Agreement” and each other similar reference, contained in the Purchase Agreement and any other Transaction Document shall from and after

or any of their respective officers, directors, affiliates, employees or agents, on the one hand, and the Investors or any of their affiliates, on the other hand, shall terminate. The Company shall not, and shall cause each of its Subsidiaries and
its and each of their respective officers, directors, employees and agents, not to, provide either Investor with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the Release Date without the express
prior written consent of such Investor. 

 5. Counterparts; Execution; Amendments. This Amendment may be executed in counterparts and
by fax or electronic signatures, all of which shall be one and the same agreement and shall have binding legal effect. No waiver under or in respect of this Amendment shall be valid unless in writing signed by the party to be charged therewith. No

Separation Date. Additionally, Employee acknowledges that he will submit to Company prior to the Separation Date, his request for reimbursement of all Company business expenses he has incurred up
through the Separation Date. The Company shall reimburse such expenses, if properly documented and supported, within fifteen (15) days of the receipt of such final request for reimbursement. Employee acknowledges that the parties to the Merger
Agreement are entering into such agreement based in part upon the Employee’s covenants and promises in this Agreement, and there is good and valuable consideration to support such promises and agreements, including, without limitation, the
payments to the Employee pursuant to the Plan as a result of the consummation of the Merger. 
 2. Health Benefits. To
the extent provided by the federal COBRA law or, if applicable, state insurance laws including CalCOBRA (collectively, “COBRA”), and by the Company’s current group health insurance policies, Employee will be eligible to continue his
group health insurance benefits (i.e. medical, dental, and vision). Provided Employee timely elects continued coverage under COBRA, the Company, as part of this Agreement, will pay Employee’s COBRA premiums (“COBRA Premiums”) for
coverage until the earliest of (a) the last day of the month following the six-month anniversary of the Separation Date, and (b) the date on which Employee ceases to be eligible for COBRA coverage. 

3. Release and Waiver by Employee. Employee, on behalf of himself and his heirs, executors, administrators, assigns and
successors, fully and forever releases and discharges Company, and, as applicable, its current, former and future parents, subsidiaries, and related entities, employee benefit plans and fiduciaries, predecessors, successors, officers, directors,
shareholders, agents, insurers, counsel, employees and assigns (collectively, “Releasees”), from any and all claims, liabilities and causes of action, of every nature, kind and description, in law, equity or otherwise, which have arisen,
occurred or existed at any time prior to his signing of this Agreement, including, without limitation, any and all claims, liabilities and causes of action arising out of or relating to Employee’s employment with Company or the cessation of
that employment. 
 4. Waiver of Employment-Related Claims. Employee waives and releases, except the potential claims
identified below, all rights, remedies, or claims he may have had or now has against Company or any of the Releasees regarding employment-related causes of action, that are applicable to Employee and Company and to which Company is subject,
including without limitation, claims of wrongful discharge, breach of contract, retaliation, breach of the covenant of good faith and fair dealing, fraud, violation of public policy, claims that he is or was a “whistleblower,” defamation,
discrimination, personal injury, physical injury, emotional distress, claims under Title VII of the Civil Rights Act of 1964, the Americans With Disabilities Act, Age Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act
of 1990, the Federal Rehabilitation Act, the California Fair Employment and Housing Act, the California Family Rights Act, the Equal Pay Act of 1963, the provisions of the California Labor Code and any other federal, state or local laws and
regulations relating to employment, conditions of employment (including wage and hour laws) and/or employment discrimination. Claims not covered by the Employee’s waiver and release are: (a) claims for unemployment insurance benefits,
(b) claims under California’s Workers Compensation laws, (c) claims relating to the Company’s express obligations under this Agreement, and (d) claims that cannot be waived or released as a matter of law (including, without
limitation, the right to file administrative claims 

  
 2 

 
before the United States Equal Employment Opportunity Commission (“EEOC”) (except for the waiver of any right to seek damages from such claims), and testifying, assisting or
participating in an investigation or proceeding by the EEOC or any comparable state or local agency. Employee represents and warrants that he does not believe he currently has any work related injuries. 

5. Waiver of Unknown Claims. In executing this Agreement, Employee waives and relinquishes all rights and benefits granted to
Employee under the provisions of Section 1542 of the California Civil Code or any similar statute or doctrine. Civil Code section 1542 provides as follows: 

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of
executing the release, which if known by him or her must have materially affected his or her settlement with the debtor. 
 Employee
acknowledges that he has read all of this Agreement, including the above Civil Code section, and that both the general release and Employee’s release of all rights and benefits pursuant to Civil Code section 1542 are fully understood. In
waiving the provisions of Section 1542 of the California Civil Code, Employee acknowledges that he may later discover facts in addition to or different from those which she now believes to be true with respect to the matters released in this
Agreement. But, he agrees that he has taken that possibility into account in reaching this Agreement, and that the releases in this Agreement will remain in effect as full and complete releases notwithstanding the discovery or existence of
additional or different facts. 
 6. Termination of Rights under Employment Agreement and Plan. Employee confirms that
the releases set forth in Sections 4 and 5 herein include, without limitation, any rights or benefits Employee may have had under the Employment Agreement and the Plan in excess of the amounts set forth in Section 1 of this Agreement, and the
Employment Agreement is terminated in all respects, except for Sections 8, 9, 11 and 14. 
 7.
Severability. If a Court rules that any provision in this Agreement is unenforceable, it will not affect the enforceability of the remaining provisions. The Court may enforce all remaining provisions to the extent permitted by law.

 8. Confidentiality of Agreement. The Parties will not disclose to others, and will keep confidential, unless compelled by
legal process, both the fact of and terms of this Agreement. The Parties may disclose this information to attorneys, accountants and other professional advisors to whom the disclosure is necessary to accomplish the purposes for which these
professional advisors were retained. Employee may disclose the terms of this Agreement to his spouse/family if they agree in advance to keep this Agreement and its terms confidential. The Parties may disclose the terms of this Agreement as necessary
to enforce its terms or to remedy for the breach of its terms. Employee acknowledges that keeping confidential the fact and terms of this Agreement is a material provision of this Agreement. 

9. Confidential Information. Employee acknowledges that, as a condition to his employment with Company, he executed a
Proprietary Information and Inventions Agreement 

  
 3 

 
(the “Proprietary Information Agreement”). This Agreement in no way affects, alters or waives Employee’s obligations or Company’s rights under the Proprietary Information
Agreement. Employee’s ongoing compliance with the Proprietary Information Agreement is a material condition to this Agreement. 

10. Non-Disparagement. Employee agrees not to disparage, in any manner, Company, its parents, successors, sister
companies, divisions or affiliates; provided, however, that Employee may respond accurately and fully to any question, inquiry or request for information when required by legal process. Company’s officers and directors will not disparage
Employee in any manner; provided, however, that Company and its officers and directors may respond accurately and fully to any question, inquiry or request for information when required by legal process. 

11. Return of Company Property. Employee must return all Company property in Employee’s possession, custody or control no
later than five (5) business days after the Separation Date, unless such property is necessary to fulfill Employee’s obligations under the Consulting Agreement. 

12. Integrated Agreement. This Agreement (together with the agreements and documents to which it specifically refers and that
certain Consulting Agreement to be entered into by and between the Party and Employee on or about the date hereof) contains the entire agreement of the Parties concerning its subject matter. The Parties did not make any promises or representations
to each other that do not appear in this Agreement. This Agreement supersedes all other agreements between the Parties excluding the Proprietary Information Agreement. 

13. Voluntary Execution. Employee has read and understands this Agreement. Employee voluntarily signs this Agreement. No person
coerced Employee to sign this Agreement. Even if any of the facts or matters upon which Employee relied in making this Agreement prove to be otherwise, this Agreement will remain in full force and effect. 

14. Waiver, Amendment and Modification. No waiver, amendment or modification of this Agreement’s terms is effective unless
it is in writing and signed by all parties affected by the waiver, amendment or modification. The Parties’ waiver of any term or condition of this Agreement will not be construed as a waiver of any other term or condition. 

15. Counterparts. This Agreement may be signed in counterparts and those counterparts will be treated as if they were one signed
document. 
 16. Employee’s Right To Release. Employee warrants and represents that (a) Employee has not
assigned or transferred, or purported to assign or transfer, and that Employee will not in the future assign or transfer to any person or entity, any right or claim released by this Agreement, any part thereof, or any interest therein, and
(b) Employee is the sole owner of the rights and claims released in this Agreement. 
 17. Venue and Governing
Law. The validity, interpretation, enforceability, and performance of this Agreement must be governed by and construed in accordance with the laws of the State of California, exclusive of its choice-of-law rules. Any action arising
under or relating to this Agreement must be commenced and maintained pursuant to Section 14 of the Employment Agreement.

 18. Consideration/Revocation Period. This Agreement is intended to release and
discharge any claims by Employee under the Age Discrimination in Employment Act. To satisfy the requirements of the Older Workers’ Benefit Protection Act, 29 U.S.C. section 626(f), as applicable:

	 	(c)	Employee understands that in signing this Agreement, Employee is not waiving rights or claims based on matters occurring after the date this Agreement is executed. 

 

	 	(d)	Employee understands and agrees that Employee is waiving rights on claims only in exchange for consideration that Employee was not already entitled to. 

 

	 	(e)	Employee understands that this Agreement does not prohibit Employee from challenging or seeking a determination in good faith of the validity of this release or waiver under the Age Discrimination in Employment Act and
does not impose any condition precedent, penalty, or costs for doing so unless specifically authorized by federal law. 

  

	 	(f)	Employee acknowledges that he has been given twenty-one (21) days to consider the terms of this Agreement (the “Consideration Period”), has taken sufficient time to consider whether to execute it, and has
chosen to enter into this Agreement knowingly and voluntarily. If Employee does not present an executed copy of this Agreement to the Company before the expiration of the Consideration Period, this Agreement and the offer it contains will lapse.

  

	 	(g)	During the seven (7) days after the execution of this Agreement (should he elect to execute it), Employee may revoke this Agreement by delivering a written revocation (via facsimile, email or personal delivery) to
