 E.
The Company and the Prior Investors desire to enter into this Agreement in order to amend, restate and replace their rights and obligations under the Prior Rights Agreement with the rights set forth in this Agreement. Section 5.2 of the Prior
Rights Agreement provides that the Prior Rights Agreement may be amended by the written consent of the Company and Investors holding shares of Preferred Stock and/or Conversion Stock (as defined therein) representing and/or convertible into at least
a majority of all the Investors’ Shares (as defined therein), and the undersigned parties to this Agreement hold a sufficient number of shares to meet these requirements. The parties hereto intend that this Agreement amend and supersede the
Prior Rights Agreement and that the Prior Rights Agreement shall be terminated upon execution of this Agreement by the parties hereto. 

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises hereinafter set forth, the parties hereto agree as
follows: 
 1. Information Rights. 

1.1 Periodic Financial Information. The Company covenants and agrees that, commencing on the date of this Agreement, for so long as any
Investor holds at least one million (1,000,000) shares of Common Stock of the Company (the “Common Stock”) issued or issuable upon the conversion of shares of Preferred Stock (including shares of Preferred Stock issuable upon
exercise of the Series C-1 Warrant) (collectively, the “Conversion Stock”) the Company will: 

(a) Annual Reports. Furnish to such Investor, as soon as practicable and in any event within two hundred seventy (270) days after
the end of each fiscal year of the Company, a consolidated balance sheet as of the end of such fiscal year, a consolidated statement of operations and a consolidated statement of cash flows of the Company and its subsidiaries for such year, setting
forth in each case in comparative form the figures from the Company’s previous fiscal year (if any), all prepared in accordance with generally accepted accounting principles and practices consistently applied and audited by nationally
recognized independent certified public accountants. 
 (b) Monthly Reports. Furnish to such Investor as soon as practicable, and in
any case within thirty (30) days after the end of each calendar month, monthly unaudited financial statements, including an unaudited balance sheet, an unaudited statement of operations and an unaudited statement of cash flows, together with a
comparison on a quarterly basis to the Company’s operating plan and budget, all prepared in accordance with generally accepted accounting principles and practices consistently applied, except as disclosed therein, with the exception that no
notes need to be attached to such statements and year-end audit adjustments may not have been made. 

  
 2 

 (c) Annual Budget. Furnish to such Investor (i) as soon as practicable and in any
event no later than thirty (30) days after the close of each fiscal year of the Company, an annual operating plan and budget, prepared on a quarterly basis, for the next immediate fiscal year, and (ii) to the extent requested by such
Investor, and as soon as reasonably practicable following the fiscal year end, a report comparing the annual budget to the financial statements of such fiscal year. The Company shall also furnish to such Investor, within a reasonable time of its
preparation, amendments to the annual budget, if any. 
 (d) Quarterly Capitalization Table. Furnish to such Investor as soon as
practicable, and in any case within forty-five (45) days after the end of each fiscal quarter of the Company, a copy of the Company’s capitalization table certified to be correct by the Company’s Chief Financial Officer or other
executive officer. 
 Notwithstanding the foregoing, as set forth in Section 1.4 below, the Company shall be under no obligation to furnish any of the
information or materials described in Subsections 1.1(a), (b), (c) and (d) above to any Investor, which the Board of Directors of the Company, in its reasonable judgment, deems to be a competitor of the Company (where for such purposes, venture
capital firms, banks and other financial institutions that do not directly operate competitive businesses shall not be deemed a competitor of the Company), except that the Company will continue to provide such Investor with any information regarding
the Company that is necessary for such Investor’s compliance with its financial reporting obligations. 
 1.2 Confidentiality.
Each Investor that is not otherwise bound by a separate non-disclosure agreement agrees to hold all information received pursuant to this Section 1 (so long as such information is not in the public domain
through no fault of the Investor) in confidence, and not to use or disclose any of such information to any third party, except (i) to the extent such information may be made publicly available by the Company, (ii) as required to be
disclosed pursuant to any partnership or similar agreement of any Investor’s investment fund; (iii) that is communicated to it free of any obligation of confidentiality from a third party who had the right to disclose such information;
(iv) that is developed by Investor or its agents independently of and without reference to any confidential information communicated by the Company; or (v) as required by applicable law. Each such Investor that is bound by a separate non-disclosure agreement agrees that such non-disclosure agreement shall apply to the information received by such Investor pursuant to this Section 1. 

1.3 Inspection Rights. The Company shall permit each Investor holding at least one million (1,000,000) shares of Conversion Stock, at
such Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account and records and to discuss the Company’s affairs, finances and accounts with its officers, all at such reasonable times as may be
requested by such Investor. Notwithstanding the foregoing, as set forth in Section 1.4 below, the Company shall be under no obligation to provide the inspection rights described in this Section 1.3 to any Investor, which the Board of Directors
of the Company, in its reasonable judgment, deems to be a competitor of the Company (where for such purposes, venture capital firms, banks and other financial institutions that do not directly operate competitive businesses shall not be deemed a
competitor of the Company), except that the Company will continue to provide such Investor with access to any information regarding the Company that is necessary for such Investor’s compliance with its financial reporting obligations. 

  
 3 

 1.4 Termination of Certain Rights. The Company’s obligations to Investors under
Sections 1.1 and 1.3 above will terminate upon the closing of the Company’s initial public offering of Common Stock pursuant to an effective registration statement filed under the U.S. Securities Act of 1933, as amended (the
“Securities Act”). The Company’s obligations to any Investor under Sections 1.1 and 1.3 above will terminate with respect to such Investor upon such Investor being deemed by the Board of Directors of the Company, in its
reasonable judgment, to be a competitor of the Company (where for such purposes, venture capital firms, banks and other financial institutions that do not directly operate competitive businesses shall not be deemed a competitor of the Company),
except that such Company obligations to such Investor will continue with respect to any information regarding the Company that is necessary for such Investor’s compliance with its financial reporting obligations. 

2. Registration Rights. 

2.1 Definitions. For purposes of this Section 2: 

(a) Registration. The terms “register,” “registration” and
“registered” refer to a registration effected by preparing and filing a registration statement in compliance with the Securities Act, and the declaration or ordering of effectiveness of such registration statement. 

(b) Registrable Securities. The term “Registrable Securities” means: 

(1) all shares of Conversion Stock issued or issuable upon conversion and/or exercise of the Preferred Stock issued under the Purchase
Agreements or pursuant to the Series C-1 Warrant, as such Purchase Agreements and Series C-1 Warrant may hereafter be amended from time to time; 

(2) any shares of Common Stock of the Company issued (or issuable upon the conversion or exercise of any warrant, right or other security
which is issued) (i) as a dividend or other distribution with respect to, or in exchange for or in replacement of, all such shares of Conversion Stock described in clause (1) of this subsection (b); excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which rights under this Section 2 are not assigned in accordance with this Agreement or any Registrable Securities with respect to which, pursuant to Section 2.11 hereof, the
holders are no longer entitled to registration rights pursuant to Sections 2.2, 2.3 or 2.4 hereof; 
 (3) any shares of Common Stock or
Common Stock issued or issuable upon conversion or exercise of any other securities acquired by the Investors pursuant to Section 3 of this Agreement or by any other means; and 

(4) all the shares of Common Stock of the Company issued or issuable upon the conversion of any shares of Series D Stock and Series F Stock
issued upon exercise of Pinnacle Warrants, provided, however, that the Pinnacle Entities are not Initiating Holders for purposes of Section 2.2 of this Agreement with respect to the shares issuable upon exercise of the Pinnacle
Warrants and the Conversion Stock issuable upon conversion thereof. 
 (c) Registrable Securities Then Outstanding. The number of
shares of “Registrable Securities then outstanding” shall mean the number of shares of Conversion Stock which are Registrable Securities that are then (1) issued and outstanding or (2) issuable pursuant to the
exercise or conversion of then outstanding and then exercisable and qualifying options, warrants or convertible securities. 

  
 4 

 (d) Holder. The term “Holder” means any person owning of record
Registrable Securities or any assignee of record of such Registrable Securities to whom rights set forth herein have been duly assigned in accordance with this Agreement; provided, however, that for purposes of this Agreement, a record
holder of shares of Preferred Stock convertible into such Registrable Securities shall be deemed to be the Holder of such Registrable Securities; and provided, further, that the Company shall in no event be obligated to register shares
of Preferred Stock and that Holders of Registrable Securities will not be required to convert their shares of Preferred Stock into Common Stock in order to exercise the registration rights granted hereunder, until immediately before the closing of
the offering to which the registration relates. 
 (e) Form S-3. The term “Form S-3” means such form under the Securities Act as is in effect on the date hereof or any successor registration form under the Securities Act subsequently adopted by the SEC which permits inclusion or
incorporation of substantial information by reference to other documents filed by the Company with the SEC. 
 (f) SEC. The term
“SEC” or “Commission” means the U.S. Securities and Exchange Commission. 
 2.2 Demand
Registration. 
 (a) Request by Holders. If the Company shall receive at any time after the earlier of three (3) years from
the date hereof, or six (6) months after the effective date of the first underwritten sale of Common Stock of the Company to the public pursuant to a registration statement filed with, and declared effective by, the SEC under the Securities
Act, covering the offer and sale of Common Stock to the public (the “IPO”), a written request from the Holders of at least a majority of the Registrable Securities then outstanding that the Company file a registration
statement under the Securities Act covering the registration of Registrable Securities pursuant to this Section 2.2, then the Company shall, within twenty (20) days after the receipt of such written request, give written notice of such
request (the “Request Notice”) to all Holders, and effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities which Holders request to be registered and included in such
registration by written notice given by such Holders to the Company within twenty (20) days after receipt of the Request Notice, subject only to the limitations of this Section 2; provided that the Registrable Securities requested
by all Holders to be registered pursuant to such request must either (i) be at least twenty percent (20%) of all Registrable Securities then outstanding or (ii) have an anticipated aggregate public offering price (before any underwriting
discounts and commissions) of not less than Five Million Dollars ($5,000,000). 
 (b) Underwriting. If the Holders initiating the
registration request under this Section 2.2 (the “Initiating Holders”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, then they shall so advise the Company as a part
of their request made pursuant to this Section 2.2 and the Company shall include such information in the written notice referred to in subsection 2.2(a). In such event, the right of any 

 

  
 5 

 Holder to include his, her, or its Registrable Securities in such registration shall be conditioned upon such
Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement with the managing underwriter or underwriters selected for such underwriting by the Company and acceptable to
a majority in interest of the Initiating Holders. Notwithstanding any other provision of this Section 2.2, if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be
underwritten then the Company shall so advise all Holders of Registrable Securities that would otherwise be registered and underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be
reduced as required by the underwriter(s) and allocated among the Holders of Registrable Securities on a pro rata basis according to the number of Registrable Securities then outstanding held by each Holder requesting registration (including the
Initiating Holders); provided, however, that the number of shares of Registrable Securities to be included in such underwriting and registration shall not be reduced unless all other securities of the Company are first entirely
excluded from the underwriting and registration. Any Registrable Securities excluded and withdrawn from such underwriting shall be withdrawn from the registration. 

(c) Maximum Number of Demand Registrations. The Company is obligated to effect only two (2) such registrations pursuant to this
Section 2.2 in which all Registrable Securities requested to be registered are included and such registrations have been deemed effective. 

(d) Deferral. Notwithstanding the foregoing, if the Company shall furnish to Holders requesting the filing of a registration statement
pursuant to this Section 2.2, a certificate signed by the President or Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and
its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, then the Company shall have the right to defer such filing for a period of not more than ninety
(90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period. 

(e) Expenses. All expenses incurred in connection with a registration pursuant to this Section 2.2, including without limitation
all registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of one counsel for the selling Holders (but excluding underwriters’
discounts and commissions) shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 2.2 shall bear such Holder’s proportionate share (based on the number of shares sold by such Holder over the
total number of shares included in such registration at the time it is declared effective) of any registration and qualification fees and all discounts, commissions or other amounts payable to underwriters or brokers in connection with such
offering. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 2.2 if the registration request is subsequently withdrawn at the request of the
Holders of 

  
 6 

 
a majority of the Registrable Securities to be registered, unless the Holders of a majority of the Registrable Securities then outstanding agree to forfeit their right to one (1) demand
registration pursuant to this Section 2.2 (in which case such right shall be forfeited by all Holders of Registrable Securities); provided further, however, that if at the time of such withdrawal, the Holders have learned
of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of their request for such registration and have withdrawn their request for registration with reasonable promptness after
learning of such material adverse change, then the Holders shall not be required to pay any of such expenses and shall retain their demand registration rights pursuant to this Section 2.2. 

2.3 Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing at least thirty (30) days
prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to any registration under Section 2.2 or Section 2.4 of this Agreement or to any employee benefit plan or a corporate reorganization or other transaction covered by Rule 145
promulgated under the Securities Act, or a registration on any registration form which does not permit secondary sales or does not include substantially the same information as would be required to be included in a registration statement covering
the sale of Registrable Securities) and will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by such Holder shall, within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall
inform the Company of the number of Registrable Securities such Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the
Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities,
all upon the terms and conditions set forth herein. 
 (a) Underwriting. If a registration statement under which the Company gives
notice under this Section 2.3 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder’s Registrable Securities to be included in a registration
pursuant to this Section 2.3 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing
to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriter(s) selected for such underwriting. Notwithstanding any other provision of
this Agreement, if the managing underwriter determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may exclude shares (including Registrable Securities)
from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first, to the Company, second to Holders requesting inclusion of their Registrable
Securities in such registration statement on a pro rata basis based on the number of Registrable Securities each such Holder has requested to be included in the registration, and third to any stockholder of the 

  
 7 

 
Company (other than a Holder) on a pro rata basis; provided, however, that the right of the underwriters to exclude Registrable Securities from the registration and underwriting as
described above shall be restricted so that (i) no Registrable Securities shall be excluded from such registration and underwriting unless all other securities held by the stockholders of the Company are similarly excluded and (ii) the
number of Registrable Securities included in any such registration is not reduced below twenty-five percent (25%) of the shares included in the registration, except for a registration relating to the Company’s IPO, from which all Registrable
Securities may be excluded. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice, given in accordance with Section 6.1 hereof, to the Company and the underwriter,
delivered at least twenty (20) days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder that is
a partnership, corporation or limited liability company, the partners, retired partners, members, retired members, stockholders and affiliated funds of such Holder, or the estates and family members of any such partners, retired partners, members
and retired members and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of
shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. 

(b) Expenses. All expenses incurred in connection with a registration made pursuant to this Section 2.3, including without
limitation all registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of one counsel for the selling Holders (but excluding
underwriters’ discounts and commissions) shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 2.3 shall bear such Holder’s proportionate share (based on the number of shares sold by such
Holder over the total number of shares included in such registration at the time it goes effective) of any registration and qualification fees and all discounts, commissions or other amounts payable to underwriters or brokers in connection with such
offering. 
 2.4 Form S-3 Registration. In case the Company shall receive from any Holder or
Holders of the Registrable Securities then outstanding a written request or requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part
of the Registrable Securities owned by such Holder or Holders, then the Company will do the following: 
 (a) Notice. Promptly give
written notice of the proposed registration and the Holder’s or Holders’ request therefor, and any related qualification or compliance, to all other Holders of Registrable Securities. 

(b) Registration. As soon as practicable, effect such registration and all such qualifications and compliances as may be so requested
and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any
other Holder or Holders joining in such request as are specified in a written request given within twenty (20) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated
to effect any such registration, qualification or compliance pursuant to this Section 2.4: 

  
 8 

 (1) if Form S-3 is not available for such offering; 

(2) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than One Million Dollars ($1,000,000); 

(3) if the Company shall furnish to the Holders a certificate signed by the President or Chief Executive Officer of the Company stating that
in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at such time, in which
event the Company shall have the right to defer the filing of the Form S-3 registration statement no more than once during any twelve (12) month period for a period of not more than ninety (90) days
after receipt of the request of the Holder or Holders under this Section 2.4; 
 (4) if the Company has, within the twelve
(12) month period preceding the date of such request, already effected two (2) registrations on Form S-3 for the Holders pursuant to this Section 2.4, excluding any registrations from which any
Registrable Securities of the Holders have been excluded; or 
 (5) in any particular jurisdiction in which the Company would be required to
qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance, unless the Company is already subject to service in such jurisdiction and except as may be required by the
Securities Act. 
 (c) Expenses. Subject to the foregoing, the Company shall file a Form S-3
registration statement covering the Registrable Securities and other securities so requested to be registered pursuant to this Section 2.4 as soon as practicable after receipt of the request or requests of the Holders for such registration. The
Company shall pay all expenses incurred in connection with each registration requested pursuant to this Section 2.4 (excluding underwriters’ or brokers’ discounts and commissions), including without limitation all filing, registration
and qualification, printers’ and accounting fees and the reasonable fees and disbursements of one (1) counsel for the selling Holder or Holders and counsel for the Company. Each Holder participating in a registration pursuant to this
Section 2.4 shall bear such Holder’s proportionate share (based on the number of shares sold by such Holder over the total number of shares included in such registration at the time it goes effective) of all discounts, commissions or other
amounts payable to underwriters or brokers in connection with such offering. 
 (d) Not Demand Registration. Form S-3 registrations shall not be deemed to be demand registrations as described in Section 2.2 above. 

2.5 Obligations of the Company. Whenever required to effect the registration of any Registrable Securities under this Agreement, the
Company shall, as expeditiously as reasonably possible: 

  
 9 

 (a) Prepare and file with the SEC a registration statement with respect to such Registrable
Securities and use reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up
to one hundred twenty (120) days or until the distribution contemplated in the Registration Statement has been completed; provided, however, that (i) such 120-day period shall be extended
for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of Common Stock (or other securities) of the Company; and (ii) in the case of any
registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, such 120-day period shall be extended, if necessary,
to keep the registration statement effective until all such Registrable Securities are sold, provided that Rule 415, or any successor rule under the Securities Act, permits an offering on a continuous or delayed basis, and provided
further that applicable rules under the Securities Act governing the obligation to file a post-effective amendment permit, in lieu of filing a post-effective amendment that (x) includes any prospectus required by Section 10(a)(3) of
the Securities Act or (y) reflects facts or events representing a material or fundamental change in the information set forth in the registration statement, the incorporation by reference of information required to be included in (x) and
(y) above to be contained in periodic reports filed pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in the registration statement. 

(b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with
such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement and, in connection with any registration on Form S-3 pursuant to Section 2.4 above, use reasonable, diligent efforts to timely file all reports required under the 1934 Act in order to maintain the right to continue to use such Form and to maintain such
registration in effect. 
 (c) Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such registration. 

(d) Use reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or Blue
Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions. 
 (e) In the event of any underwritten public offering, enter into and perform its
obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting hereby agrees to also enter into and perform its obligations under such an
agreement. 

  
 10 

 (f) Notify each Holder of Registrable Securities covered by such registration statement at any
time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. As promptly as practicable thereafter, the Company will
prepare and file with the SEC, and furnish without charge to the appropriate Holders and managing underwriter(s), if any, an amendment or supplement to such registration statement or prospectus in order to cause such registration statement or
prospectus not to include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and will
furnish such copies thereof as the Holders or any underwriters may reasonably request. 
 (g) Cause all such Registrable Securities
registered pursuant hereunder to be listed on each national securities exchange or trading system on which similar securities issued by the Company are then listed. 

(h) Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such registration. 
 2.6 Furnish Information. It shall be a
condition precedent to the obligations of the Company to take any action pursuant to Sections 2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them, and
the intended method of disposition of such securities as shall be required to timely effect the registration of their Registrable Securities. 

2.7 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 

2.8 Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.2, 2.3 or 2.4:

 (a) By the Company. To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners,
officers, members, stockholders, agents and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the
Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively, the “Violations” and, individually, a “Violation”): 

(1) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or supplements thereto; or 

  
 11 

 (2) the omission or alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein not misleading; or 
 (3) any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any federal or state securities law in connection with the offering covered by such
registration statement. 
 The Company will reimburse each such Holder, partner, officer, member, stockholder, agent or director, underwriter or controlling
person for any legal or other expenses reasonably incurred by them, within three months after a request for reimbursement has been received by the Company, in connection with investigating or defending any such loss, claim, damage, liability or
action; provided however, that the indemnity agreement contained in this subsection 2.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent
of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs
in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, officer, director, underwriter or controlling person of such Holder. 

(b) By Selling Holders. To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities, under such registration
statement or any of such other Holder’s partners, members, stockholders, directors, agents or officers or any person who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, partner, member, stockholder, agent, director, officer or controlling person of such other Holder may become
subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration. Each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, partner, officer, member, stockholder, agent, director or controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action within three months after a request for reimbursement has been received by the indemnifying Holder; provided, however, that the indemnity agreement contained in this
subsection 2.8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and
provided further, that the total amounts payable in indemnity by a Holder under this Section 2.8(b) in respect of any and all Violations shall not exceed the net proceeds received by such Holder in the registered offering out of
which such Violations arise. 

  
 12 

 (c) Notice. Promptly after receipt by an indemnified party under this Section 2.8 of
notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.8, deliver to the indemnifying party a
written notice of the commencement thereof. 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 the defense
thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation
of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding.
The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 2.8, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.8. 

(d) Contribution. If the indemnification provided for in this Section 2.8 is held by a court of competent jurisdiction to be
unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by such
indemnified party with respect to such loss, liability, claim, damage or expense in the proportion that is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions
that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and the indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, and the parties’ relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission. In any such case, (A) no such Holder will be required to contribute any amount in excess of the net proceeds of all such Registrable Securities offered and sold by
such Holder pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation. 
 (e) Conflict with Underwriting Agreement. Notwithstanding the foregoing,
to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement will control; provided, however, that the failure of the underwriting agreement to address a provision addressed in this agreement shall not be such a conflict. 

(f) Survival. The obligations of the Company and Holders under this Section 2.8 shall survive the completion of any offering of
Registrable Securities in a registration statement, and otherwise. No indemnifying party, in the defense of any such claim or litigation, 

  
 13 

 shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any
settlement which 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 to such claim or litigation. 

2.9 “Market Stand-Off” Agreement. Each Holder hereby agrees that it shall not, to the
extent requested by the Company or an underwriter of securities of the Company, sell, otherwise transfer or dispose of, any Registrable Securities or other shares of stock of the Company then owned by such Holder (other than to donees or partners of
the Holder who agree to be similarly bound) for up to one hundred eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act (or if required by such underwriter(s), such longer
period of time as is necessary to enable such underwriter(s) to issue a research report or make a public appearance that relates to an earnings release or announcement by the Company within 18 days prior to or after the date that is 180 days after
the effective date of the registration statement relating to such offering, but in any event not to exceed 210 days following the effective date of the registration statement relating to such offering); provided, however, that: 

(a) the foregoing provisions of this Section 2.9 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting
agreement; 
 (b) such agreement shall be applicable only to the first such registration statement of the Company which covers securities to
be sold on its behalf to the public in an underwritten offering but not to Registrable Securities sold pursuant to such registration statement; 

(c) (i) all officers and directors of the Company then holding Common Stock of the Company (or securities convertible into or exercisable for
Common Stock) and (ii) all holders of equity securities representing 1% or more of the Company’s outstanding Common Stock (assuming conversion or exercise of all convertible or exercisable securities), enter into similar agreements; and 

(d) any discretionary waiver or termination of the restrictions of such agreement by the Company or representatives of the underwriters shall
apply to all of the Company’s stockholders on a pro rata basis, based upon the number of shares held by each stockholder, on an as-converted to Common Stock basis. 

For purposes of this Section 2.9, the term “Company” shall include any wholly-owned subsidiary of the Company into which the Company merges or
consolidates. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the shares subject to this Section and to impose stop transfer instructions with respect to the
Registrable Securities and such other shares of stock of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. Each Holder further agrees to enter into any agreement
reasonably required by the underwriters to implement the foregoing within any reasonable timeframe so requested. 

  
 14 

 2.10 Rule 144 Reporting. With a view to making available the benefits of certain rules and
regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, after such time as a public market exists for the Common Stock of the Company, the Company agrees to: 

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public; 

(b) Use reasonable, diligent efforts to file with the Commission in a timely manner all reports and other documents required of the Company
under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and 
 (c) So long
as a Holder owns any Registrable Securities, to furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the
effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to the reporting requirements
of the Exchange Act), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing
a Holder to sell any such securities without registration (at any time after the Company has become subject to the reporting requirements of the Exchange Act). 

2.11 Termination of the Company’s Obligations. The Company shall have no obligations pursuant to Sections 2.2 through 2.4 with
respect to: (a) any request or requests for registration made by any Holder on a date more than five (5) years after the closing date of the Company’s IPO; or (b) any Registrable Securities proposed to be sold by a Holder in a
registration pursuant to Section 2.2, 2.3 or 2.4 if, in the reasonable opinion of counsel to the Company, all such Registrable Securities proposed to be sold by a Holder may be sold in a three (3) month period without registration under the
Securities Act pursuant to Rule 144 under the Securities Act, the Company has completed its IPO and such Holder holds less than one percent (1%) of the outstanding Common Stock of the Company (assuming conversion or exercise of all convertible or
exercisable securities for such purposes). 
 2.12 Limitations on Subsequent Registration Rights. From and after the date of
this Agreement, the Company shall not, without the prior written consent of the Holders of at least a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the
Company which would allow such holder or prospective holder (a) to include such securities in any registration filed under Section 2.2 or 2.3 hereof, unless under the terms of such agreement, such holder or prospective holder may include
such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of the Registrable Securities of the Holders which is included, or (b) to make a demand registration which could result
in such registration statement being declared effective prior to the earlier of either of the dates set forth in subsection 2.2(a). 

  
 15 

 3. Right of First Refusal. 

3.1 General. Each Holder (as defined in Section 2.1(d)) and any party to whom such Holder’s rights under this Section 3
have been duly assigned in accordance with Section 5.1(b) (each such Holder or assignee being hereinafter referred to as a “Rights Holder”) has the right of first refusal to purchase such Rights Holder’s Pro Rata
Share (as defined below), of all (or any part) of any New Securities (as defined in Section 3.2) that the Company may from time to time issue after the date of this Agreement, provided, however, such Rights Holder shall have no
right to purchase any such New Securities if such Rights Holder cannot demonstrate to the Company’s reasonable satisfaction that such Rights Holder is at the time of the proposed issuance of such New Securities an “accredited
investor” as such term is defined in Regulation D under the Securities Act. A Rights Holder’s “Pro Rata Share” for purposes of this right of first refusal is the ratio of (a) the number of Registrable
Securities as to which such Rights Holder is the Holder (and/or is deemed to be the Holder under Section 2.1(d), excluding any then unvested Registrable Securities for such purpose), to (b) a number of shares of Common Stock of the Company
equal to the sum of (1) the total number of shares of Common Stock of the Company then outstanding (excluding any then unvested shares of Common Stock for such purpose) plus (2) the total number of shares of Common Stock of the Company into
which all then outstanding shares of Preferred Stock of the Company are then convertible plus (3) the number of shares of Common Stock of the Company for which all then outstanding options and warrants are then exercisable (excluding any then
unvested options for such purpose). Subject to compliance with applicable securities laws, each Rights Holder shall be entitled to apportion the right of first offer hereby granted it among itself and its partners, members, affiliates and persons
and entities under common investment management in such proportions as it deems appropriate. 
 3.2 New Securities. “New
Securities” shall mean any Common Stock or Preferred Stock of the Company, whether now authorized or not, and rights, options or warrants to purchase such Common Stock or Preferred Stock, and securities of any type whatsoever that are,
or may become, convertible or exchangeable into such Common Stock or Preferred Stock; provided, however, that the term “New Securities” does not include: 

(a) Exempted Securities (as defined in the Company’s Restated Certificate of Incorporation); 

(b) any securities issued in connection with a Common Stock Event (as defined in the Company’s Restated Certificate of Incorporation); and

 (c) any shares of Common Stock or Preferred Stock (or options, or warrants or rights to acquire same), issued or issuable hereafter that
are approved by the vote of the holders of at least a majority of the outstanding Preferred Stock, voting as a single class, as being excluded from the definition of “New Securities”. 

3.3 Procedures. In the event that the Company proposes to undertake an issuance of New Securities, it shall give to each Rights Holder a
written notice of its intention to issue New Securities (the “Notice”), describing the type of New Securities and the price and the general terms upon which the Company proposes to issue such New Securities given in
accordance with Section 6.1 hereof. Each Rights Holder shall have twenty (20) days from the 

  
 16 

 date such Notice is effective, as determined pursuant to Section 6.1 hereof based upon the manner or method
of notice, to agree in writing to purchase up to such Rights Holder’s Pro Rata Share of such New Securities for the price and upon the general terms specified in the Notice by giving written notice to the Company and stating therein the
quantity of New Securities to be purchased (not to exceed such Rights Holder’s Pro Rata Share). If any Rights Holder fails to so agree in writing within such twenty (20) day period to purchase such Rights Holder’s full Pro Rata Share
of an offering of New Securities (a “Nonpurchasing Holder”), then such Nonpurchasing Holder shall forfeit the right hereunder to purchase that part of his Pro Rata Share of such New Securities that he, she or it did not so
agree to purchase and the Company shall promptly give each Rights Holder who has timely agreed to purchase his full Pro Rata Share of such offering of New Securities (a “Purchasing Holder”) written notice of the failure of
any Nonpurchasing Holder to purchase such Nonpurchasing Rights Holder’s full Pro Rata Share of such offering of New Securities (the “Overallotment Notice”). Each Purchasing Holder shall have a right of overallotment such
that such Purchasing Holder may agree to purchase a portion of the Nonpurchasing Holders’ unpurchased Pro Rata Shares of such offering on a pro rata basis according to the relative Pro Rata Shares of the Purchasing Holders, at any time within
five (5) days after receiving the Overallotment Notice. 
 3.4 Failure to Exercise. In the event that the Rights Holders fail to
exercise in full the right of first refusal within such twenty (20) plus five (5) day period, then the Company shall have ninety (90) days thereafter to sell the New Securities with respect to which the Rights Holders’ rights of
first refusal hereunder were not exercised, at a price and upon general terms not more favorable to the purchasers thereof than specified in the Company’s Notice to the Rights Holders. In the event that the Company has not issued and sold the
New Securities within such ninety (90) day period, then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the Rights Holders pursuant to this Section 3. 

3.5 Termination. This right of first refusal shall terminate (a) immediately prior to the effective time of the Company’s IPO,
or (b) upon the consummation of a Change of Control of the Company (as defined in the Restated Certificate), provided, however, that such Change of Control has been approved by the holders of at least a majority of the Registrable
Securities. 
 4. Covenants of the Parties. 

4.1 Vesting. Unless otherwise approved by the Company’s Board of Directors (including a majority of the directors elected
solely by the holders of Preferred Stock), after the date of this Agreement all shares of Common Stock or options to purchase Common Stock issued to any employee pursuant to any benefit, bonus or incentive plan or agreement will vest with respect to
twenty-five percent (25%) of the shares or options on the one-year anniversary following the date of issuance (or, with respect to an employee’s initial grant, on the
one-year anniversary following the date of such employee’s commencement date with the Company), with the remaining seventy-five percent (75%) of the shares or options to vest monthly over the next three
(3) years (provided in each case so long as such employee remains employed by the Company) and on such other terms and conditions approved by the Company’s Board of Directors. In the event that the Company’s Board of Directors
approves an option or 

  
 17 

 other equity award that allows any employee to purchase unvested shares of Common Stock, then such employee shall
be bound by an agreement granting the Company the right to repurchase the unvested shares for the original purchase price in the event that the employee’s employment with the Company terminates for any reason, subject to release of such
repurchase right upon the vesting schedule approved by the Board of Directors of the Company. 
 4.2 True Books and Records.
The Company will maintain true books and records of account in which full and correct entries will be made of all its business transactions pursuant to a system of accounting established and administered in accordance with generally accepted
accounting principles consistently applied (except as noted therein), and will set aside on its books all such proper accruals and reserves as shall be required under generally accepted accounting principles consistently applied. 

4.3 Reservation of Common Stock. The Company will at all times reserve and keep available, solely for issuance and delivery upon
the conversion of the Preferred Stock, all Common Stock issuable from time to time upon such conversion. 
 4.4 Visitation Rights.
For as long as Pinnacle Entities holds any shares of Common Stock issued or issuable upon exercise or conversion of any security of the Company, the Company shall allow one representative designated by the Pinnacle Entities to attend all
meetings of the Company’s Board of Directors in a nonvoting capacity, and in connection therewith, the Company shall give such representative copies of all notices, minutes, consents and other materials, financial or otherwise, which the
Company provides to its Board of Directors; provided, however, that the Company reserves the right to exclude such representative from access to any material or meeting or portion thereof if the Company believes upon advice of counsel that such
exclusion is reasonably necessary to preserve the attorney-client privilege, to protect highly confidential information or for other similar reasons. The decision of the Board with respect to the privileged or confidential nature of such information
shall be final and binding. As a condition to such visitation rights, the representative shall enter into a non-disclosure agreement in a form reasonably acceptable to the Company. 

4.5 Proprietary Information and Inventions Agreement. The Company shall require all employees and consultants to execute and
deliver a Proprietary Information and Inventions Agreement substantially in a form approved by the Company’s counsel or Board of Directors. 

4.6 Key Man Life Insurance. The Company shall obtain and maintain key man life insurance policies on the Company’s senior
management as designated by the Board of Directors, each in the amount of $2,000,000, the proceeds of which are payable to the Company, and shall maintain such insurance as long as the insureds are affiliated with the Company in a management
capacity. The Company hereby agrees that it shall not assign, borrow against or pledge such policies. 
 4.7 Russian Design Center.
The Company shall establish a design center (the “Design Center”) in Russia before the end of calendar year 2012 in accordance with the Russian Investment Plan attached to this Agreement as Exhibit B and shall ensure
that the Design Center always complies with the provisions of the Russian Investment plan. The Company and Rusnano 

  
 18 

 acknowledge that the Company’s failure to establish the Design Center in accordance with this
Section 4.7 will cause Rusnano damages and losses of types and in amounts which are impossible to compute and ascertain with certainty as a basis for recovery by Rusnano of actual damages, and that liquidated damages represent a fair,
reasonable and appropriate estimate thereof. Accordingly, in lieu of any damages for such breach and as the sole remedy to Rusnano for any breach of this Section 4.7, the Company and Rusnano agree that in the event of any Material Breach (as
defined below) by the Company, liquidated damages in the amount of Five Hundred Thousand Dollars ($500,000) shall be assessed and paid by the Company to Rusnano no later than 20 business days from the date of such Material Breach, without Rusnano
being required to present any evidence of the amount or character of actual damages sustained by reason thereof; provided that in no event shall the total damages owed under this Section 4.7 exceed the amount of Five Hundred Thousand Dollars
($500,000). Such liquidated damages are intended to represent estimated actual damages and are not intended as a penalty, and the Company shall pay them to Rusnano. The parties agree that no Investor, other than Rusnano, shall have any right
pursuant to this Section 4.7 and that the covenants set forth in this Section 4.7 are being made by the Company solely for the benefit of Rusnano. For purposes of this Section 4.7, a “Material Breach” shall be
deemed to occur if and only if (i) a Russian subsidiary from which the Design Center will operate has not been created by December 31, 2012, (ii) by the end of the 3 year period starting from the date of establishment of the Russian subsidiary
the Company has not made aggregate investments in the Russian subsidiary that owns the Design Center of at least $3,000,000 in cash, or (iii) if by the earlier of (x) 3 year anniversary of the date the Design Center is established and
(y) December 31, 2015, the Russian subsidiary has not hired at least 11 engineers for the purposes of the fulfillment of the Russian Investment Plan. 

4.8 Qualified Small Business Stock. The Company shall use commercially reasonable efforts to cause the shares of Preferred Stock, as
well as any shares into which such shares are converted, within the meaning of Section 1202(f) of the Internal Revenue Code of 1986, as amended (the “Code”), to constitute “qualified small business stock” as
defined in Section 1202(c) of the Code; provided, however, that such requirement shall not be applicable if the Board of Directors of the Company determines, in its good-faith business judgment, that such qualification is
inconsistent with the best interests of the Company. The Company shall submit to its stockholders (including the Investors) and to the Internal Revenue Service any reports that may be required under Section 1202(d)(1)(C) of the Code and the
regulations promulgated thereunder. In addition, within twenty (20) business days after any Investor’s written request therefor, the Company shall, at its option, either (i) deliver to such Investor a written statement indicating
whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business stock” as defined in Section 1202(c) of the Code or (ii) deliver to such Investor such factual information in the
Company’s possession as is reasonably necessary to enable such Investor to determine whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business stock” as defined in
Section 1202(c) of the Code. 
 4.9 Termination. The covenants set forth in Section 4 (other than Section 4.7, which
shall only terminate in accordance with the Russian Investment Plan) shall terminate (a) immediately prior to the effective time of the Company’s IPO, or (b) the consummation of a Change of Control of the Company (as defined in the
Company’s Restated Certificate of Incorporation).

 5. Assignment and Amendment. 

5.1 Assignment. Notwithstanding anything herein to the contrary: 

(a) Information Rights. The rights of an Investor under Section 1 hereof may be assigned only to a party who acquires from
an Investor (or an Investor’s permitted assigns) at least that minimum number of shares of Preferred Stock and/or an equivalent number (on an as-converted basis) of shares of Conversion Stock described in
Section 1.1 or 1.3 hereof, respectively; provided that any such assignee of such rights is not deemed by the Board of Directors of the Company, in its reasonable judgment, to be a competitor of the Company (where for such purposes,
venture capital firms, banks and other financial institutions that do not directly operate competitive businesses shall not be deemed a competitor of the Company); provided further that any Holder may assign information rights to a
partner, member, retired partner, former member, stockholder or affiliate of such Holder without restriction as to the minimum share requirement set forth above; provided further, that any such assignee shall receive such assigned
rights subject to all the terms and conditions of this Agreement, including without limitation the provisions of this Section 5. 
 (b)
Registration Rights. The registration rights of a Holder under Section 2 hereof may be assigned only to a party who acquires at least 250,000 shares of Preferred Stock issued under the Purchase Agreements or pursuant to the Series C-1 Warrant (or, if a lesser amount, all shares of Preferred Stock held by a Holder) and/or an equivalent number (on an as-converted basis) of Registrable Securities issued
upon conversion thereof (unless the Company waives such minimum share requirement); provided, however, that no party may be assigned any of the foregoing rights unless the Company is given written notice by the assigning party at the
time of such assignment stating the name and address of the assignee and identifying the securities of the Company as to which the rights in question are being assigned; provided further, that any such assignee of such rights is not
deemed by the Board of Directors of the Company, in its reasonable judgment, to be a competitor of the Company (where for such purposes, venture capital firms, banks and other financial institutions that do not directly operate competitive
businesses shall not be deemed a competitor of the Company); provided further, that any such assignee shall receive such assigned rights subject to all the terms and conditions of this Agreement, including without limitation the
provisions of this Section 5; and provided further, that any Holder may assign registration rights to a partner, member, retired partner, former member, stockholder or affiliate of such Holder without restriction as to the minimum
share requirement set forth above. 
 5.2 Amendment and Waiver of Rights. Any provision 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 (i) Company and (ii) Investors (and/or any of their permitted successors or
assigns) holding shares of Preferred Stock and/or Conversion Stock representing and/or convertible into at least a majority of all the Investors’ Shares (as defined below); provided, that if (A) any amendment or waiver would have
the effect of waiving the rights of Intel (as defined below), Rusnano, Xilinx, Inc., GLOBALFOUNDRIES U.S. Inc. or Walden Riverwood Ventures, L.P. to purchase securities as set forth in Section 3 (other than regarding securities carved out of
the definition of New Securities as of the date hereof), (B) such party did not consent to such amendment or 

  
 20 

 waiver, and (C) any one or more other Rights Holder(s) actually participate(s) in an issuance of such
securities, then Intel, Rusnano, Xilinx, Inc., GLOBALFOUNDRIES U.S. Inc. or Walden Riverwood Ventures, L.P., as the case may be, shall be permitted to participate in such issuance in accordance with the provisions of Section 3 notwithstanding
such purported amendment or waiver; ; provided, further, that Section 4.4 may not be amended or waived without the written consent of the Pinnacle Entities; provided, further, that any amendment or waiver of
Section 4.7 or Exhibit B hereto shall require the written consent of Rusnano; provided, further, that any amendment or waiver of Section 4.8 shall require the written consent of GLOBALFOUNDRIES U.S. Inc.;
provided, further, any amendment or waiver of Intel’s or Rusnano’s rights in Section 6.14(b) shall require the written consent of Intel or Rusnano, as the case may be, and any amendment or waiver of Intel’s or
GLOBALFOUNDRIES U.S. Inc.’s rights in Section 6.14(c) shall require the written consent of Intel or GLOBALFOUNDRIES U.S. Inc., as the case may be; provided, further, that any amendment or waiver of any of the foregoing
provisos related to Intel, Rusnano, Xilinx, Inc. GLOBAL FOUNDREIS U.S. Inc. or Walden Riverwood Ventures, L.P., or of this proviso, shall require the written consent of Intel, Rusnano, Xilinx, Inc. GLOBAL FOUNDREIS U.S. Inc. or Walden Riverwood
Ventures, L.P., as the case may be; and provided, further, any amendment, termination or waiver that would reduce or eliminate any right or benefit to an Investor hereunder in manner that is different and disproportionate from any
other Investor holding the same series of Preferred Stock will require separate approval of such Investor. As used herein, the term “Investors’ Shares” shall mean the shares of Common Stock then issuable upon conversion
of all then outstanding shares of Preferred Stock issued under the Purchase Agreements plus all then outstanding shares of Conversion Stock that were issued upon the conversion of any shares of Preferred Stock issued under the Purchase Agreements.
Any amendment or waiver effected in accordance with this Section 5.2 shall be binding upon each Investor, each Holder, each permitted successor or assignee of such Investor or Holder and the Company. 

6. General Provisions. 

6.1 Notices. Any and all notices required or permitted to be given to a party pursuant to the provisions of this Agreement will be in

 (a) if to an Investor, at such Investor’s respective address as set forth on Exhibit A
hereto. 
 (b) if to the Company, marked “Attention: Chief Executive Officer”, at Aquantia Corp., 700 Tasman Drive, Milpitas,
CA 95035, with a copy to Cooley LLP, 1114 Avenue of the Americas, New York, NY 10036, attention: Babak Yaghmaie, Esq. 
 6.2 Entire
Agreement. This Agreement and the documents referred to herein, together with all the Exhibits hereto, constitute the entire agreement and understanding of the parties with respect to the subject matter of this Agreement, and supersede any and
all prior understandings and agreements, whether oral or written, between or among the parties hereto with respect to the specific subject matter hereof. 

6.3 Governing Law, Jurisdiction and Venue. This Agreement will be governed by and construed in accordance with the laws of the State of
California, without giving effect to that body of laws pertaining to conflict of laws. The parties agree that any action brought by any party under or in relation to this Agreement, including without limitation to interpret or enforce any provision
of this Agreement, shall be brought in, and each party agrees to and does hereby submit to the jurisdiction and venue of, any state or federal court located in the Northern District of California. 

6.4 Severability. If any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid,
illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced, such provision shall be stricken from this Agreement
and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement. Notwithstanding the forgoing, if the value of this
Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be binding, then both parties agree to substitute such
provision(s) through good faith negotiations. 
 6.5 Third Parties. Nothing in this Agreement, express or implied, is intended to
confer upon any person, other than the parties hereto and their successors and assigns, any rights or remedies under or by reason of this Agreement. 

6.6 Successors And Assigns. Subject to the provisions of Section 5.1, this Agreement, and the rights and obligations of the parties
hereunder, will be binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators and legal representatives. 

6.7 Titles and Headings. The titles, captions and headings of this Agreement are included for ease of reference only and will be
disregarded in interpreting or construing this Agreement. Unless otherwise specifically stated, all references herein to “sections” and “exhibits” will mean “sections” and “exhibits” to this Agreement. 

  
 22 

 6.8 Counterparts. This Agreement may be executed in any number of counterparts, each of
which when so executed and delivered will be deemed an original, and all of which together shall constitute one and the same agreement. 

6.9 Costs And Attorneys’ Fees. In the event that any action, suit or other proceeding is instituted concerning or arising out of
this Agreement or any transaction contemplated hereunder, the prevailing party shall recover all of such party’s costs and attorneys’ fees incurred in each such action, suit or other proceeding, including any and all appeals or petitions
therefrom. 
 6.10 Adjustments for Stock Splits, Etc. Wherever in this Agreement there is a reference to a specific number of shares
of Common Stock or Preferred Stock of the Company of any class or series, then, upon the occurrence of any subdivision, combination, stock dividend, recapitalization or the like of such class or series of stock, the specific number of shares so
referenced in this Agreement shall automatically be proportionally adjusted to reflect the affect on the outstanding shares of such class or series of stock by such subdivision, combination, stock dividend, recapitalization or the like. 

6.11 Aggregation of Stock. All shares held or acquired by affiliated entities or persons shall be aggregated together for the
purpose of determining the availability of any rights under this Agreement. 
 6.12 Further Assurances. The parties agree to execute
such further documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement. 

6.13 Facsimile Signatures. This Agreement may be executed and delivered by facsimile or other means of electronic communication with
originals to follow to Open Joint Stock Company “RUSNANO” as soon as possible after the Closing and upon such delivery the facsimile signature, including in portable document format, will be deemed to have the same effect as if the
original signature had been delivered to the other party. The failure to deliver the original signature copy and/or the nonreceipt of the original signature copy shall have no effect upon the binding and enforceable nature of this Agreement. 

6.14 Confidentiality. 

(a) Disclosure of Financing Terms. Each party acknowledges that the terms and conditions (collectively, the “Financing
Terms”) of this Agreement, the Series H Agreement, Series G Agreement, the Series F Agreement, the Series E Agreement, the Series D Agreement, the Series C and Series C-1 Agreement, the Series C-1 Warrant, each of the Related Agreements (as defined in the Series C and Series C-1 Agreement, the Series E Agreement, the Series F Agreement, the Series G Agreement and
the Series H Agreement), the Stock Purchase Agreement dated November 13, 2009 by and between the Company and Intel (the “Repurchase Agreement”), and all exhibits, restatements and amendments hereto and thereto (collectively,
the “Financing Agreements”), including their existence, shall be considered confidential information and shall not be disclosed by it to any third party except in accordance with the provisions of this Section 6.14. 

  
 23 

 (b) Press Releases. No announcement regarding the Financing Terms or any Investor under
any of the Repurchase Agreement, Series C and Series C-1 Agreement, Series D Agreement, the Series E Agreement, the Series F Agreement, the Series G Agreement or the Series H Agreement in a press release,
conference, advertisement, announcement, professional or trade publication, mass marketing materials or otherwise to the general public may be made without the prior written consent of the Company, Intel and, with respect to the Series F Agreement
only, Open Joint Stock Company “RUSNANO”; provided, however, that with the consent of the Company, and the Investors holding a majority of the Registrable Securities held by all Investors, the Financing Terms of the Series H
Agreement and names of Investors participating in the Series H investment may be announced and such would not require Intel’s written consent. 

(c) Permitted Disclosures. Notwithstanding the foregoing, any party may disclose any of the Financing Terms to its current or bona fide
prospective acquirors and investors, directors, employees, investment bankers, lenders, accountants and attorneys (and, in the case of an Investor, such Investor’s partners and members), in each case only where such persons or entities are
under nondisclosure obligations customary for such applicable acquirors, investors, partners, members, directors, employees, investment bankers, lenders, accountants and attorneys, and Intel (together with Intel Corporation and Intel
Corporation’s other direct or indirect wholly-owned subsidiaries, “Intel Entities”) may disclose its investment (either directly or indirectly through any Intel Entity) in the Company and the Financing Terms (excluding
any Financing Terms that are specific to an Investor other than Intel, to the extent not already publicly disclosed by the Company or such other Investor) to third parties or to the public at its sole discretion and, if it does so, the other parties
hereto shall have the right to disclose to third parties any such information disclosed in a press release or other public announcement or disclosure by any Intel Entity. Additionally, upon receipt of prior written consent of the Company,
GLOBALFOUNDRIES U.S. Inc. may disclose its investment (either directly or indirectly through any affiliate) in the Company and the Financing Terms (excluding any Financing Terms that are specific to an Investor other than GLOBALFOUNDRIES U.S. Inc.,
to the extent not already publicly disclosed by the Company or such other Investor) to third parties or to the public and, if it does so, the other parties hereto shall have the right to disclose to third parties any such information disclosed in a
press release or other public announcement or disclosure by GLOBALFOUNDRIES U.S. Inc. 
 (d) Legally Compelled Disclosure. In the
event that any party is requested or becomes legally compelled (including without limitation, pursuant to securities laws and regulations) to disclose the existence of any of the Financing Terms, or the Financing Agreements, in contravention of the
provisions of this Section 6.14, such party (the “Disclosing Party”) shall provide the other parties (the “Non-Disclosing Parties”) with prompt written
notice of that fact before such disclosure and will use its reasonable efforts to fully cooperate with the Non-Disclosing Parties to seek a protective order, confidential treatment, or other appropriate remedy
with respect to the disclosure. In such event, the Disclosing Party shall furnish for disclosure only that portion of the information which is legally required and shall exercise its reasonable efforts to obtain reliable assurance that confidential
treatment will be accorded such information to the extent reasonably requested by any Non-Disclosing Party and to the maximum extent possible under law. The Disclosing Party agrees that it will provide the Non-Disclosing Parties with drafts of any documents, press releases or other filings in which the Disclosing Party 

  
 24 

 is required to disclose any of the Financing Agreements or Financing Terms or any other confidential information
subject to the terms of this Section 6.14 at least five (5) business days prior to the filing or disclosure thereof, and that it will make any changes to such materials as requested by any
Non-Disclosing Party to the extent permitted by law or any rules and regulations of the SEC or the Russian Federation, as applicable. If confidential treatment is requested by any Non-Disclosing Party, the Disclosing Party agrees to file such a request on such Non-Disclosing Party’s behalf and use its reasonable efforts in responding to any SEC or
other governmental entity’s comments to pursue assurance that confidential treatment will be granted, in both cases fully cooperating with such Non-Disclosing Party (including, without limitation,
providing such Non-Disclosing Party with the opportunity to review and comment on the request and the responses to any such SEC comments). The Disclosing Party will not file any Financing Agreement with any
governmental authority or any regulatory body, or disclose the identity of any Non-Disclosing Party or any other Financing Terms in any filing except as permitted above. Notwithstanding the foregoing, the
Company shall be permitted, without notice to the Non- Disclosing Parties, to disclose in connection with the filing of a Form D Notice of Exempt Offering of Securities with the applicable governmental authorities, the aggregate amount of securities
sold pursuant to the Series D Agreement so long as such disclosure does not include the identity of any Non-Disclosing Party. 

(e) Tax Treatment and Confidentiality. Notwithstanding anything herein to the contrary, each party hereto (and each employee,
representative, or other agent of each party) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transaction contemplated in the Financing Agreements and all materials of any kind
(including opinions or other tax analyses) that are provided to any party except to the extent necessary to comply with any applicable federal or state securities laws. This authorization is not intended to permit disclosure of any other information
or any portion of any materials to the extent not related to the tax treatment or tax structure of the transaction, including but not limited to, (i) the identities of participants or potential participants in the transaction, (ii) the
existence or status of any negotiations, (iii) any pricing or financial information (except to the extent such pricing or financial information is related to the tax treatment or tax structure of the transaction), or (iv) any other term or
detail not relevant to the tax treatment or the tax structure of the transaction. The parties to this Agreement have no knowledge or reason to know that a disclosure related to the tax treatment or tax structure of the transaction contemplated in
the Financing Agreements is otherwise limited. 
 (f) Other Information. The provisions of this Section 6.14 shall be in
addition to, and not in substitution for, the provisions of any separate nondisclosure agreement executed by any of the parties hereto with respect to the transactions contemplated by the Financing Agreements. Disclosures and exchanges of
confidential information between the Company and Intel Entities (including, without limitation, any exchanges of information with any Intel board observer) shall be governed by the terms of the Corporate
Non-Disclosure Agreement No. 4043669, dated as of January 6, 2005, executed by the Company and Intel (the “CNDA”); provided, however, that the parties hereto agree and acknowledge
that Confidential Information (as defined in the CNDA) shall include any oral disclosure made during any of the Company’s board of directors meetings (including all committees thereof) for those portions of such meetings where Intel’s
board observer was in attendance, as such attendance is documented in the minutes of the applicable meeting, and provided further, however, that the Intel Entities 

  
 25 

 shall be responsible to the Company for any liability that such individual would have had such individual been a
party to the CNDA. Without limiting the foregoing, the Company agrees that neither the confidentiality provision set forth in Section 1.2 of this Agreement nor any similar confidentiality obligation or restriction contained in any of the
Financing Agreements (except for this Section 6.14) shall be binding upon the Intel Entities. 
 (g) Notices. All notices
required under this Section 6.14 shall be made pursuant to Section 6.1 of this Agreement.

Aquantia Corp.’s (the “Company”) Russian Design Center (“RDC”) Investment Plan 

Following the date hereof but prior to December 31, 2012, the Company undertakes to form a subsidiary (the “Subsidiary”) in St Petersburg
Russia which will operate the RDC. The objective of the RDC is to expand the Company’s research and development team in specific areas of Integrated Circuit design expertise complementing the Company’s existing design center in California,
specifically in the following areas: Chip Integration & CAD, Firmware / DSP and Applications software. 
 In order to operate the RDC, the
Subsidiary will lease office space and is expected to require the installation and sourcing of various office equipment, IT hardware infrastructure (consistent with planned operations of RDC), as well as various software and tools licenses. In
addition, the Company undertakes to hire Integrated Circuit design engineers for the Subsidiary in accordance with the following schedule (4 engineers by the end of year 1 following opening of RDC, 3 additional engineers by the end of year 2 (7 in
total by end of year 2), 4 additional engineers by the end of year 3 (11 in total by end of year 3)). 
 The Company undertakes to hire staff at RDC with
the specific areas of IC design expertise as follows: 
  

	 	•	 	Chip Integration & CAD 

  

	 	•	 	Responsible for “back-end” chip design 

  

	 	•	 	Headcount of 1 at end of year 1 following opening of RDC, headcount of 2 at end of year 2, headcount of 3 at end of year 3 

  

	 	•	 	Firmware / DSP 

  

	 	•	 	Responsible for software development related to the firmware of the chip or DSP algorithms 

  

	 	•	 	Headcount of 2 at end of year 1 following opening of RDC, headcount of 3 at end of year 2, headcount of 4 at end of year 3 

  

	 	•	 	Applications software 

  

	 	•	 	Responsible for software development on layer-2+ type of components 

  

	 	•	 	Headcount of 1 at end of year 1 following opening of RDC, headcount of 2 at end of year 2, headcount of 4 at end of year 3 

The Company’s preliminary estimates of the initial costs in connection with establishment of the Subsidiary’s operations and purchasing and
installing IT hardware infrastructure and equipment for the Subsidiary, will be approximately $50,000. The RDC will be financed by the Company through monthly fund transfer following its opening. 

In order to accelerate the launch of operations at the RDC, the Company has entered into a non-binding MOU with Milandr. 

The Company undertakes: 

  
 B-1 

	1.	To transfer funds to the Subsidiary to an account of the Subsidiary at a bank acceptable to Rusnano; 

  

	2.	To prepare a budget for the Subsidiary annually, which includes quarterly budget periods; 

  

	3.	To (or to cause the Subsidiary’s Chief Executive Officer or Chief Financial Officer to) provide Rusnano with quarterly reports on the Subsidiary’s use of funds, within 40 days of the end of each fiscal
quarter; and 

  

	4.	To permit Rusnano representatives (for so long as it owns any shares of the Company’s Preferred Stock), at Rusnano’s expense, to visit and inspect the Subsidiary’s properties, to examine its books of
account and records and to discuss the Subsidiary’s affairs, finances and accounts with its officers, all at such reasonable times agreed to by Rusnano and the Company (and in any event, subject to at least 48 hour advance notice by Rusnano to
the Company), it being understood that the confidentiality obligations set forth in Section 1.2 of the Amended and Restated Investors’ Right Agreement which this Exhibit B is a part of shall be applicable to all information received by
Rusnano pursuant to this Exhibit B (subject to the exceptions set forth therein).

 Exhibit 10.1 

FORM OF DIRECTOR & OFFICER 

INDEMNIFICATION AGREEMENT 

THIS INDEMNITY AGREEMENT (the “Agreement”) is made and entered into as of
                                    , 2017, between Aquantia
Corp., a Delaware corporation (the “Company”), and
                                    
(“Indemnitee”). 
 RECITALS 

A. Highly competent persons have become more reluctant to serve corporations as directors or officers or in other capacities unless they are
provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

B. Although the furnishing of liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities has been
a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher
premiums and with more exclusions. At the same time, directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other
things, matters that traditionally would have been brought only against the Company or business enterprise itself. The By-laws and Certificate of Incorporation of the Company require the Company to indemnify
the executive officers and directors of the Company and empower the Company to indemnify other officers, employees and agents as authorized by the General Corporation Law of the State of Delaware (“DGCL”). The By-laws and Certificate of Incorporation and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the
Company and members of the Board, officers and other persons with respect to indemnification; 
 C. The uncertainties relating to liability
insurance and to indemnification have increased the difficulty of attracting and retaining such persons; 
 D. The Board has determined that
the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such
protection in the future; 
 E. It is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to
advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

F. This Agreement is a supplement to and in furtherance of the By-laws and Certificate of Incorporation
of the Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and 

 G. Indemnitee does not regard the protection available under the Company’s By-laws and Certificate of Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires
Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he or she be so indemnified; and 

H. Indemnitee may have certain rights to indemnification and/or insurance provided by other entities and/or organizations which Indemnitee and
such other entities and/or organizations intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material condition to
Indemnitee’s willingness to serve on the Board and/or as an officer of the Company. 
 I. This Agreement supersedes and replaces in its
entirety any previous Indemnification Agreement entered into between the Company and the Indemnitee. 
 NOW, THEREFORE, in consideration of
Indemnitee’s agreement to serve as an officer or a director from and after the date hereof, the parties hereto agree as follows: 
 1.
Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without
limiting the generality thereof: 
 (a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be
entitled to the rights of indemnification provided in this Section l(a) if, by reason of his or her Corporate Status (as hereinafter defined), the Indemnitee is, or is threatened to be made, a party to or participant in any
Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred by him or her, or on his or her behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner
the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of his or her Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this
Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee acted in good
faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim,
issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may be made. 

  
 2 

 (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he or she shall be indemnified to the
maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or her or on his or
her behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall
be deemed to be a successful result as to such claim, issue or matter. 
 2. Additional Indemnity. In addition to, and without regard
to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts
paid in settlement actually and reasonably incurred by him or her or on his or her behalf if, by reason of his or her Corporate Status, he or she is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by
or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this
Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful. 

3. Contribution. 
 (a)
Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if
joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company
hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined
in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee
shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit
or proceeding), the Company shall contribute to the amount of 

  
 3 

 
Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all
officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from
which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and
all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the
events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the law may require to be considered. The relative fault of the Company and all officers, directors or employees of
the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the
degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive. 

(c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by
officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 
 (d) To the fullest
extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by
Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed
fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding;
and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is,
by reason of his or her Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he or she shall be indemnified against all Expenses actually and reasonably incurred
by him or her or on his or her behalf in connection therewith. 
 5. Advancement of Expenses. Notwithstanding any other provision of
this Agreement, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a
statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by

  
 4 

 
Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that
Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. 

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for
Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any
question as to whether Indemnitee is entitled to indemnification under this Agreement: 
 (a) To obtain indemnification under this
Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent
Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any
failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and
materially prejudices the interests of the Company. 
 (b) Upon written request by Indemnitee for indemnification pursuant to the first
sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board:
(i) unless a Change in Control has occurred: (1) by a majority vote of the Disinterested Directors, even though less than a quorum, (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested
Directors, even though less than a quorum, (3) if there are no Disinterested Directors or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee,
or (4) if so directed by the Board, by the stockholders of the Company; and (ii) if a Change in Control has occurred, then by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee. For
purposes hereof, Disinterested Directors are those members of the Board who are not parties to the action, suit or proceeding in respect of which indemnification is sought by Indemnitee. 

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board. Indemnitee may, within 10 days after such
written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the
requirements of “Independent Counsel” as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely
objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as 

  
 5 

 
Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written
request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware
or other court of competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by
the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The
Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees
and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither the
failure of the Company (including by its Board or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the
applicable standard of conduct, nor an actual determination by the Company (including by its Board or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that
Indemnitee has not met the applicable standard of conduct. 
 (e) Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their
duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the
Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement.
Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(f) If the person, persons or entity empowered or selected under Section 6 to determine whether Indemnitee is
entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have been made and
Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not

  
 6 

 
materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in
good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the
determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such
determination, the Board or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt
and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty
(60) days after having been so called and such determination is made thereat. 
 (g) Indemnitee shall cooperate with the person,
persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board or stockholder of the Company shall act reasonably and in
good faith in making a determination regarding the Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the
person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless
therefrom. 
 (h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a
party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without
limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone
seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (i)
The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of
itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or,
with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was unlawful.

 7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made
pursuant to Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within ten
(10) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such
determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent
jurisdiction, of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant
to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication. 
 (b)
In the event that a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this
Section 7 shall be conducted in all respects as a de novo trial on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). 

(c) If a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled
to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a
material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of his or her rights
under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on his or her behalf, in advance, any and all
expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably incurred by him or her in such judicial adjudication, regardless of whether Indemnitee ultimately is
determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 
 (e) The Company shall be precluded from
asserting in any judicial proceeding commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company
is bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore)
advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by Indemnitee in connection 

  
 8 

 
with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies
maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding. 
 8.
Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 

(a) The rights of indemnification as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at
any time be entitled under applicable law, the Certificate of Incorporation, the By-laws, any agreement, a vote of stockholders, a resolution of Board or otherwise. No amendment, alteration or repeal of this
Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration or repeal. To
the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Certificate of Incorporation, By-laws and this
Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every
other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other right or remedy. 
 (b) To the extent that the Company maintains an
insurance policy or policies providing liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that
such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary
under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as
a result of such proceeding in accordance with the terms of such policies. 
 (c) The Company hereby acknowledges that Indemnitee has or may
have in the future certain rights to indemnification, advancement of expenses and/or insurance provided by other entities and/or organizations (collectively, the “Secondary Indemnitors”). The Company hereby agrees
(i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Secondary Indemnitors to advance expenses or 

  
 9 

 
to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee
and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation or Bylaws of the
Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Secondary Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Secondary Indemnitors
from any and all claims against the Secondary Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Secondary Indemnitors on behalf of
Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Secondary Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement
or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Secondary Indemnitors are express third party beneficiaries of the terms of this Section 8(c). 

(d) Except as provided in paragraph (c) above, in the event of any payment under this Agreement, the Company shall be subrogated to the
extent of such payment to all of the rights of recovery of Indemnitee (other than against the Secondary Indemnitors), who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as
are necessary to enable the Company to bring suit to enforce such rights. 
 (e) Except as provided in paragraph (c) above, the Company
shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

 (f) Except as provided in paragraph (c) above, the Company’s obligation to indemnify or advance Expenses hereunder to
Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee
has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this
Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made to or
on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision, provided, that the foregoing shall not affect the
rights of Indemnitee or the Secondary Indemnitors set forth in Section 8(c) above; 

  
 10 

 (b) for an accounting of profits made from the purchase and sale (or sale and purchase) by
Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act, or similar provisions of state statutory law or common law; 

(c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any
Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company
provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; 
 (d) with respect
to remuneration paid to Indemnitee if it is determined by final judgment or other final adjudication that such remuneration was in violation of law (and, in this respect, both the Company and Indemnitee have been advised that the Securities and
Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for
adjudication, as indicated in the last paragraph of this Section 9 below); 
 (e) a final judgment or other final adjudication is made
that Indemnitee’s conduct was in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct (but only to the extent of such specific determination); 

(f) in connection with any claim for reimbursement of the Company by Indemnitee of any bonus or other incentive-based or equity-based
compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to
Section 304 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of
Section 306 of the Sarbanes-Oxley Act), if Indemnitee is held liable therefor (including pursuant to any settlement); or 
 (g) on
account of conduct that is established by a final judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal profit or advantage to which Indemnitee is not legally entitled. 

For purposes of this Section 9, a final judgment or other adjudication may be reached in either the underlying proceeding or action in
connection with which indemnification is sought or a separate proceeding or action to establish rights and liabilities under this Agreement. 

Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement to indemnify
Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act, or in any registration statement filed with the SEC under the Securities Act. Indemnitee
acknowledges that paragraph (h) of Item 512 of Regulation S-K currently generally requires the Company to undertake in connection with any registration statement filed under the Securities Act to submit
the issue of the enforceability of Indemnitee’s rights under this 

  
 11 

 
Agreement in connection with any liability under the Securities Act on public policy grounds to a court of appropriate jurisdiction and to be governed by any final adjudication of such issue.
Indemnitee specifically agrees that any such undertaking shall supersede the provisions of this Agreement and to be bound by any such undertaking. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during the period Indemnitee is
an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so long
as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of his or her Corporate Status, whether or not he or she is acting or serving in any such capacity at the time
any liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including
any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

11. Security. To the extent requested by Indemnitee and approved by the Board, the Company may at any time and from time to time provide
security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or released without the prior
written consent of the Indemnitee. 
 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby in
order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 
 13.

Expenses incurred in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, including
without limitation the premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of

 (i) “Independent Counsel” means a law firm, or a member of a law firm,
that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to
matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the
foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an
action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and
damages arising out of or relating to this Agreement or its engagement pursuant hereto. 
 (j) “Person” for purposes
of the definition of Beneficial Owner and Change in Control set forth above, shall have the meaning as set forth in Sections 13(d) and 14(d) of the Exchange Act; provided, however, that Person shall exclude (i) the Company, (ii) any
trustee or other fiduciary holding securities under an employee benefit plan of the Company, and (iii) any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of
stock of the Company. 
 (k) “Proceeding” includes any threatened, pending or completed action, suit, arbitration,
alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal,

investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of the fact that Indemnitee is or was an officer or director of the Company, by reason of any
action taken by him or her or of any inaction on his or her part while acting as an officer or director of the Company, or by reason of the fact that he or she is or was serving at the request of the Company as a director, officer, employee, agent
or fiduciary of another corporation, partnership, joint venture, trust or other Enterprise; in each case whether or not he or she is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification
can be provided under this Agreement; including one pending on or before the date of this Agreement, but excluding one initiated by an Indemnitee pursuant to Section 7 of this Agreement to enforce his or her rights under
this Agreement. 
 (l) “Securities Act” shall mean the Securities Act of 1933, as amended. 

14. Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of
any other provision. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any provision hereof conflicts with
any applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

 16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving
any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company
of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the Company. 

17. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed
effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business
day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with
