 1. Definitions. As used herein, capitalized terms not otherwise defined herein shall have the
following respective meanings: 
 (a) “Acquisition” means any transaction or series of related
transactions involving (i) any consolidation or merger of the Company with another entity (other than a merger or consolidation effected exclusively to change the Company’s domicile) or any other corporate reorganization, in which the
stockholders of the Company in their capacity as such immediately prior to such merger, consolidation or reorganization, own less than a majority of the Company’s (or the surviving or successor entity’s) outstanding voting power
immediately after such merger, consolidation or reorganization, or (ii) the sale of all or substantially all of the assets of the Company. 
 (b) “Act” means the Securities Act of 1933, as amended. 

(c) “Common Stock” means the Common Stock of the Company. 

(d) “Date of Grant” means June 4, 2013. 

(e) “Holder” means the initial holder of this Warrant set forth in the first paragraph of this Warrant and any
other person or entity which becomes a holder of this Warrant pursuant to the terms of this Warrant. 
 (f) “IPO”
means the initial public offering of the Company’s Common Stock effected pursuant to a registration statement on Form S-l (or its successor) filed under the Act. 
 (g) “Shares” means the shares of Common Stock of Company issuable upon exercise of this Warrant. 
 2. Term. The purchase right represented by this Warrant is exercisable, in whole or in part, at any time and from time to time from the Date of Grant through the earlier of (i) the seventh
anniversary of the Date of Grant, (ii) the third anniversary of the effective date of the registration statement filed in connection with the Company’s IPO or (iii) the consummation of an Acquisition. 

 3. Method of Exercise; Payment; Issuance of New Warrant: Net Issuance. 

(a) Subject to Section 2 hereof, the purchase right represented by this Warrant may be exercised by the Holder, in whole or in part
and from time to time, at the election of the Holder, by (a) the delivery of the notice of exercise substantially in the form attached hereto as Exhibit A-l, duly completed and executed, at the principal office of the Company and by the payment
to the Company, by certified or bank check, or by wire transfer to an account designated by the Company of an amount equal to the then applicable Exercise Price multiplied by the number of Shares then being purchased; (b) if in connection with
a registered public offering of the Company’s securities, the delivery of the notice of exercise form attached hereto as Exhibit A-2, duly completed and executed, at the principal office of the Company together with notice of arrangements
reasonably satisfactory to the Company for payment to the Company from the proceeds of the sale of shares to be sold by the Holder in such public offering of an amount equal to the then applicable Exercise Price per share multiplied by the number of
Shares then being purchased; or (c) exercise of the “net issuance” right provided for in Section 3(b) hereof. The person or persons in whose name(s) Shares shall be registered upon exercise of this Warrant shall be deemed to have
become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the shares represented thereby (and such shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates
upon which this Warrant is exercised. In the event of any exercise of this Warrant, certificates for the shares of stock so purchased shall be delivered to the Holder as soon as possible and in any event within thirty (30) days after such
exercise and, unless this Warrant has been fully exercised or expired, a new Warrant representing the portion of the Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder (subject to
delivery of the old Warrant to the Company) as soon as possible and in any event within such thirty-day period; provided, however, that at such time as the Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as
amended, if requested by the Holder, the Company shall cause its transfer agent to deliver the certificate representing Shares issued upon exercise of this Warrant to, or credit the securities account of, a broker or other person (as directed by the
Holder exercising this Warrant) within the time period required to settle any trade made by the Holder after exercise of this Warrant. 
 (b) Right to Convert Warrant into Stock: Net Issuance. 
 (i) Right to
Convert. In addition to and without limiting the rights of the Holder under the terms of this Warrant, the Holder shall have the right to convert this Warrant or any portion thereof (the “Conversion Right”) into shares of
Common Stock as provided in this Section 3(b) at any time or from time to time during the term of this Warrant. Upon exercise of the Conversion Right with respect to a particular number of shares subject to this Warrant (the
“Converted Warrant Shares”), the Company shall deliver to the Holder (without payment by the Holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Common Stock
as is determined according to the following formula: 
  

			
	X=	  	 B – A

		  	Y

  

			
	 Where: X =
	  	the number of shares of Common Stock that shall be issued to Holder
	 Y =
	  	the fair market value of one share of Common Stock
	 A =
	  	the aggregate Exercise Price of the specified number of Converted Warrant Shares immediately prior to the exercise of the Conversion Right (i.e., the number of Converted
Warrant Shares multiplied by the Exercise Price)
	B =	  	the aggregate fair market value of the specified number of Converted Warrant Shares (i.e., the number of Converted Warrant Shares multiplied by the fair market value
of one Converted Warrant Share)

  
 -2-

 (ii) Method of Exercise. The Conversion Right may be exercised by the Holder by the
delivery by Holder of a written statement (which may be in the form of Exhibit A-l or Exhibit A-2 hereto) specifying that the Holder thereby intends to exercise the Conversion Right and indicating the number of shares subject to this Warrant which
are being surrendered (referred to in Section 3(b)(i) hereof as the Converted Warrant Shares) in exercise of the Conversion Right. Such conversion shall be effective upon receipt by the Company of the aforesaid written statement, or on such
later date as is specified therein, and, at the election of the Holder, may be made contingent upon the closing of the sale of the Company’s Common Stock to the public in a public offering pursuant to a registration statement under the Act (a
“Public Offering”). 
 (iii) Determination of Fair Market Value. For purposes of this
Section 3(b), “fair market value” of a share of Common Stock as of a particular date (the “Determination Date”) shall mean: 
 (1) If the Conversion Right is exercised in connection with and contingent upon a Public Offering, and if the Company’s registration statement relating to such Public Offering
(“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “Price to Public” specified in the final prospectus with respect to such Public Offering.

 (2) If the Conversion Right is exercised in connection with an Acquisition, then the fair market value shall be the value
received in such Acquisition by the holders of Common Stock if the consideration is cash or stock for which there is a liquid public market, or if there is no liquid public market, then the fair market value shall be reasonably be determined in good
faith by the board of directors of the Company. 
 (3) If the Conversion Right is not exercised in connection with and
contingent upon a Public Offering or an Acquisition, then as follows: 
 (A) If regularly traded on a nationally
recognized securities exchange, interdealer quotation system or over-the-counter market (not including any secondary market for securities of non-public companies), the fair market value of the Common Stock shall be deemed to be the closing price or
last sale price of the Common Stock on the trading day immediately prior to the Determination Date; and 
 (B)
If there is no liquid public market for the Common Stock, then fair market value shall be reasonably determined in good faith by the board of directors of the Company. 
 (iv) If closing prices or last sale prices are no longer reported by a securities exchange or other trading system, the closing price or last sale price shall be that which is reported by such securities
exchange or other trading system at 4:00 p.m. New York City time on the applicable trading day. 
 4. Stock Fully Paid:
Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all preemptive
rights and taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue
upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant.

 5. Adjustment of Exercise Price and Number of Shares. The number and kind of
securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the occurrence of certain events, as follows: 

(a) Corporate Events. In case of any reclassification or change of securities of the class issuable upon exercise of this Warrant
(other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in case of any merger of the Company with or into another corporation (other than a merger
with another corporation in which the Company is the acquiring and the surviving corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant and other than an Acquisition
that results in the exercise or termination of this Warrant) (each, a “Corporate Event’), the Company, or such successor corporation, as the case may be, shall duly execute and deliver to the Holder a new Warrant (in form and
substance satisfactory to the Holder), or the Company shall make appropriate provision without the issuance of a new Warrant, so that the Holder shall have the right to receive upon exercise of this Warrant, at a total purchase price not to exceed
that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the shares of Common Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property
receivable upon such Corporate Event by a holder of the number of shares of Common Stock then purchasable under this Warrant. Any new Warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 5. The provisions of this Section 5(a) shall similarly apply to successive Corporate Events. 
 (b) Subdivision or Combination of Shares. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Common Stock, the
Exercise Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision and the Exercise Price shall be proportionately increased and the number of Shares issuable
hereunder shall be proportionately decreased in the case of a combination. 
 (c) Stock Dividends and Other Distributions.
If the Company at any time while this Warrant is outstanding and unexpired shall (i) pay a dividend with respect to Common Stock payable in Common Stock, then the Exercise Price shall be adjusted, from and after the date of determination of
shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total
number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution;
or (ii) make any other distribution with respect to Common Stock (except any distribution specifically provided for in Sections 5(a) and 5(b)), then, in each such case, provision shall be made by the Company such that the Holder shall receive
upon exercise of this Warrant a proportionate share of any such dividend or distribution as though it were the holder of the Common Stock as of the record date fixed for the determination of the shareholders of the Company entitled to receive such
dividend or distribution. 
 (d) Adjustment of Number of Shares. Upon each adjustment in the Exercise Price, the number of
Shares of Common Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Exercise Price by a fraction, the
numerator of which shall be the Exercise Price immediately prior to such adjustment and the denominator of which shall be the Exercise Price immediately thereafter. 
 (e) Charter. A true and complete copy of the Company’s Certificate of Incorporation, as amended through the Date of Grant, is attached hereto as Exhibit B (the “Charter”).
The Company shall provide the Holder with any restatement, amendment, modification or waiver of the Charter promptly after the same has been made. 

  
 -4-

 6. Notice of Adjustments. Whenever the Exercise Price or the number of Shares
purchasable hereunder shall be adjusted pursuant to Section 5 hereof, the Company shall deliver to Holder a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of
the adjustment, the method by which such adjustment was calculated, and the Exercise Price and the number of Shares purchasable hereunder after giving effect to such adjustment. 

7. Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise or conversion hereunder,
but in lieu of such fractional shares the Company shall make a cash payment therefor based on the fair market value of the Common Stock on the date of exercise or conversion as reasonably determined in good faith by the Company’s Board of
Directors. 
 8. Compliance with Act; Disposition of Warrant or Shares of Common Stock. 

(a) Compliance with Act. The Holder, by acceptance hereof, agrees that this Warrant, and the shares of Common Stock to be issued
upon exercise hereof are being acquired for investment and that the Holder will not offer, sell or otherwise dispose of this Warrant, or any shares of Common Stock to be issued upon exercise hereof except under circumstances which will not result in
a violation of the Act or any applicable state securities laws. Upon exercise of this Warrant, unless such exercise is registered under the Act and any applicable state securities laws or an exemption from such registration is available, the Holder
shall confirm in writing that the shares of Common Stock so purchased are being acquired for investment and not with a view toward distribution or resale in violation of the Act and shall confirm such other matters related thereto as may be
reasonably requested by the Company. This Warrant and all shares of Common Stock issued upon exercise of this Warrant (unless no longer required under applicable law) shall be stamped or imprinted with a legend in substantially the following form:

 “THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO
SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED,
(iii) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE PROVISIONS OF SECTION 8 OF THE WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY.”

 Said legend shall be removed by the Company, upon the request of the Holder, at such time as the restrictions on the transfer
of the applicable security shall have terminated. In addition, in connection with the issuance of this Warrant, the Holder specifically represents to the Company by acceptance of this Warrant as follows: 

(1) The Holder is aware of the Company’s business affairs and financial condition, and has acquired information about the Company
sufficient to reach an informed and knowledgeable decision to acquire this Warrant. The Holder is acquiring this Warrant for its own account for investment purposes only and not with a view to, or for the resale in connection with, any
“distribution” thereof in violation of the Act. The Holder also represents that it has not been formed for the specific purpose of acquiring this Warrant or the Shares. The Holder further represents that Holder does not currently have any
contract, undertaking, agreement or arrangement with any unaffiliated person to sell or transfer to such person or any unaffiliated third person any of the Shares. 
 (2) The Holder understands that this Warrant has not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature
of the Holder’s investment intent as expressed herein. 
 (3) The Holder further understands that this Warrant must be held
indefinitely unless subsequently registered under the Act and qualified under any applicable state securities laws, or unless exemptions from registration and qualification are otherwise available. The Holder is aware of the provisions of Rule 144,
promulgated under the Act. 

  
 -5-

 (4) The Holder agrees that the Shares shall be subject to the market standoff provisions in
Section 1.14 of the Amended and Restated Investors’ Rights Agreement, dated May 26, 2011, by and among the Company and the investors named therein, as such agreement may be amended or restated from time to time and as the provisions
thereof may be waived from time to time. The Holder further agrees that, in connection with the execution of this Warrant, the Holder will execute a lock-up agreement, a form of which is attached hereto as Exhibit C. 

(5) The Holder is an “accredited investor” as such term is defined in Rule 501 of Regulation D promulgated under the Act.

 (b) Disposition of Warrant or Shares. With respect to any offer, sale or other disposition of this Warrant or any
shares of Common Stock acquired pursuant to the exercise of this Warrant, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of counsel (at the Company’s
expense), or other evidence, if reasonably satisfactory to the Company, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state
securities law then in effect) of this Warrant or such shares of Common Stock and indicating whether or not under the Act certificates for this Warrant or such shares of Common Stock to be sold or otherwise disposed of require any restrictive legend
as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory opinion or other evidence, the Company, as promptly as practicable but no later than fifteen
(15) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of this Warrant or such shares of Common Stock, all in accordance with the terms of the notice delivered to the Company. If a
determination has been made pursuant to this Section 8(b) that the opinion of counsel or other evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such determination
has been made. Notwithstanding the foregoing, this Warrant or such shares of Common Stock may, as to such federal laws, be offered, sold or otherwise disposed of (i) pursuant to an effective registration statement covering such securities or
(ii) in accordance with Rule 144 or 144A under the Act, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 or 144A
have been satisfied. Each certificate representing this Warrant or the shares of Common Stock thus transferred (except a transfer pursuant to an effective registration statement or Rule 144 or 144A) shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions. 
 (c) Applicability of Restrictions. Neither
any restrictions of any legend described in this Warrant nor the requirements of Section 8(b) above shall apply to any transfer of, or grant of a security interest in, this Warrant (or the Common Stock obtainable upon exercise thereof) or any
part hereof (i) to a partner of the Holder if the Holder is a partnership or to a member of the Holder if the Holder is a limited liability company, (ii) to a partnership of which the Holder is a partner or to a limited liability company
of which the Holder is a member, or (iii) to a single affiliate of the Holder if the Holder is a corporation, where, in each case, the transferee is an “accredited investor”; provided, however, in any such transfer, if
applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of this Warrant as if an original holder hereof. 
 9. Rights as Shareholders; Information. No Holder, as a holder of this Warrant, shall be entitled to vote or receive dividends or be deemed the holder of Common Stock for any purpose, nor shall
anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof,
until this Warrant shall have been exercised or converted and the Shares purchasable upon the exercise or conversion hereof shall have 

  
 -6-

 become deliverable, as provided herein. Notwithstanding the foregoing, the Company will transmit to the
Holder such information, documents and reports as are generally distributed to the holders of any class or series of the securities of the Company concurrently with the distribution thereof to the shareholders. In addition, the Company agrees to
provide in a timely manner any information reasonably requested by the Holder to enable the Holder and its affiliates to comply with their accounting reporting requirements. Prior to the effective date of an IPO, Company will also provide Holder the
following information: 
 (a) As soon as practicable (and in any event within thirty (30) days after the end of each
quarter), unaudited financial statements for such quarter, certified by Company’s Chief Executive Officer or Chief Financial Officer to fairly present in all material respects the data reflected therein. 

(b) As soon as practicable (and in any event within five (5) days after completion), audited financial statements for such year,
setting forth in comparative form the corresponding figures for the preceding fiscal year, and accompanied by an audit report and unqualified opinion of the independent certified public accountants of recognized national standing selected by
Company. 
 (c) Copies of 409(A) valuation reports, if any, within thirty (30) days of completion. 

(d) Upon request by the Holder, detailed capitalization tables (by round and investor). 

10. Additional Rights. 
 (a) Notice of Transactions. The Company shall provide the Holder with at least seven (7) days’ written notice prior to closing thereof of the terms and conditions of any of the following
transactions (to the extent the Company has notice thereof): (i) any Acquisition of the Company or any liquidation or winding up of the Company, (ii) any declaration of a dividend or distribution, whether in cash, property, stock, or other
securities; (iii) any offer for subscription or sale pro rata to the holders of the outstanding shares of Common Stock any additional shares of any class or series of the Company’s stock (other than pursuant to contractual pre-emptive
rights); or (iv) the effectiveness of the IPO. 
 (b) Exercise Prior to Expiration. To the extent this Warrant is
not previously exercised as to all of the Shares subject hereto, and if the fair market value of one share of the Common Stock is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised pursuant to
Section 3(b) above (even if not surrendered) immediately before its expiration. For purposes of such automatic exercise, the fair market value of one share of Common Stock upon such expiration shall be determined pursuant to Section 3(b).
To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 10(b), the Company agrees to promptly notify the Holder of the number of Shares, if any, the Holder is to receive by reason of such
automatic exercise. 
 11. Representations and Warranties. The Company represents and warrants to the Holder as of the
date hereof as follows: 
 (a) This Warrant has been duly authorized and executed by the Company and is a valid and binding
obligation of the Company enforceable in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and the rules of law or principles at equity governing specific performance,
injunctive relief and other equitable remedies.

Common Stock and the holders thereof are as set forth in the Charter. 
 (d) The execution and delivery of this Warrant are not,

or order applicable to the Company, and do not and will not conflict with or contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument of which the Company is a party or by which it is bound or
require the consent or approval of, the giving of notice to, the registration or filing with or the taking of any action in respect of or by, any Federal, state or local government authority or agency or other person, except for the filing of
notices pursuant to federal and state securities laws, which filings will be effected by the time required thereby. 
 (e) There
are no actions, suits, audits, investigations or proceedings pending or, to the knowledge of the Company, threatened against the Company in any court or before any governmental commission, board or authority which, if adversely determined, could
have a material adverse effect on the ability of the Company to perform its obligations under this Warrant.

assets, and all of the obligations of the Company relating to the Common Stock issuable upon the exercise or conversion of this Warrant shall survive the exercise, conversion and termination of this Warrant and all of the covenants and agreements of

amended and restated in its entirety to read as follows:

 The purpose of the Corporation is to engage in any

 ARTICLE III 

The address of the corporation’s registered office in the State of Delaware is 2711 Centerville Road, Suite 400, City of Wilmington,
County of New Castle, State of Delaware 19808. The name of its registered agent at such address is the Corporation Service Company. 
 ARTICLE IV 
 The Corporation is authorized to issue two classes of
stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares of capital stock that the Corporation shall have authority to issue is 276,987,915. The total number of shares
of Common Stock the Corporation shall have authority to issue is 155,203,902 with a par value of $0.001 per share. The total number of shares of Preferred Stock the Corporation shall have authority to issue is 121,784,013 with a par value of $0,001
per share, 26,137,758 of which shares shall be designated Series A Preferred Stock (the “Series A Preferred Stock”), 26,727,505 of which shares shall be designated Series B Preferred Stock (the “Series B Preferred
Stock”), 24,683,530 of which shares 

 
shall be designated Series C Preferred Stock (the “Series C Preferred Stock”), 12,100,007 of which shares shall be designated Series D Preferred Stock (the “Series D
Preferred Stock”) and 32,135,213 of which shares shall be designated Series E Preferred Stock (the “Series E Preferred Stock”). 
 The relative rights, preferences, privileges, limitations and restrictions granted to or imposed on the respective classes and series of the shares of capital stock or the holders thereof are as follows:

 4.1 Dividends. The holders of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series
D Preferred Stock and Series E Preferred Stock shall be entitled to receive dividends, on a pari passu basis, when, as and if declared by the Corporation’s Board of Directors, out of any assets legally available therefor, prior and in
preference to any declaration or payment of any dividend on the Corporation’s Common Stock or any other class or series of stock (payable other than in Common Stock or other securities or rights convertible into, or entitling the holder thereof
to receive directly or indirectly, additional shares of Common Stock (“Common Stock Equivalents”)) at the rate of (i) $0.0428 per share of Series A Preferred Stock (as adjusted for any stock dividend, stock split, combination,
reorganization, recapitalization, reclassification or other similar event with respect to such share) per annum, (ii) $0.0614 per share of Series B Preferred Stock (as adjusted for any stock dividend, stock split, combination, reorganization,
recapitalization, reclassification or other similar event with respect to such share) per annum, (iii) $0.0763 per share of Series C Preferred Stock (as adjusted for any stock dividend, stock split, combination, reorganization,
recapitalization, reclassification or other similar event with respect to such share) per annum, (iv) $0.0898 per share of Series D Preferred Stock (as adjusted for any stock dividend, stock split, combination, reorganization, recapitalization,
reclassification or other similar event with respect to such share) per annum and (v) $0.1004 per share of Series E Preferred Stock (as adjusted for any stock dividend, stock split, combination, reorganization, recapitalization,
reclassification or other similar event with respect to such share) per annum. The right to receive dividends on shares of any series of Preferred Stock shall not be cumulative, and no right to such dividends shall accrue to holders of any series of
Preferred Stock by reason of the fact that dividends on such shares are not declared or paid in any year. Upon conversion of any share of any series of Preferred Stock pursuant to subsection (A) or (B) of Section 4.3, all dividends
declared but unpaid on such share at the time of conversion shall be paid in cash or shares of Common Stock at the option of the Corporation’s Board of Directors at the then fair market value as determined in good faith by the
Corporation’s Board of Directors. Except as permitted in this Section 4.1, no dividends shall be declared or paid, and no distribution shall be made, on any shares of Common Stock or any other class or series of stock (other than a
dividend payable solely in Common Stock or Common Stock Equivalents) unless (A) a dividend in an amount equal to the dividend described in the first sentence of this Section 4.1 for the current year is paid or set aside for payment on each
outstanding share of each series of Preferred Stock and (B) any additional dividends declared or paid in any year are declared or paid, or any distributions made on any shares of Common Stock, among the holders of Preferred Stock and Common
Stock then outstanding based on the number of shares of Common Stock held by each such holder (assuming full conversion of each series of Preferred Stock).

 4.2 Liquidation Preference. 

(A) Preferred Stock Preference. In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or
involuntary, the holders of shares of Series E Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the Corporation’s assets or funds to the holders of the other series of the Preferred Stock, the
Corporation’s Common Stock or any other capital stock of the Corporation ranking junior to the Preferred Stock by reason of their ownership thereof, an amount equal to $1.2545 per share (as adjusted for any stock dividend, stock split or
combination with respect to such share after the date upon which the Restated Certificate is filed with the Secretary of State of the State of Delaware (the “Filing Date”) (the “Series E Original Issue Price”) for
each share of Series E Preferred Stock held by them, plus an additional amount equal to any dividends declared but unpaid on each such share. If, upon such liquidation, dissolution or winding up, the assets and funds distributed are insufficient to
permit the payment to each holder of Series E Preferred Stock of the full aforesaid preferential amounts, the entire assets and funds legally available for distribution shall be distributed ratably to such holders in proportion to the preferential
amount each such holder is otherwise entitled to receive with respect to the shares of Series E Preferred Stock held by such holder. Upon the completion of the distribution to the holders of Series E Preferred Stock required by this subsection
(A) of Section 4.2, the holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall be entitled to receive, on a pari passu basis, prior and in preference to any
distribution of any of the Corporation’s assets or funds to the holders of the Corporation’s Common Stock or any other capital stock of the Corporation ranking junior to the Preferred Stock by reason of their ownership thereof, an amount
equal to (i) $0.535 per share (as adjusted for any stock dividend, stock split or combination with respect to such share after the Filing Date) (the “Series A Original Issue Price”) for each share of Series A Preferred Stock
held by them, plus an additional amount equal to any dividends declared but unpaid on each such share, (ii) $0.767 per share (as adjusted for any stock dividend, stock split or combination with respect to such share after the Filing Date) (the
“Series B Original Issue Price”) for each share of Series B Preferred Stock held by them, plus an additional amount equal to any dividends declared but unpaid on each such share, (iii) $0.9542 per share (as adjusted for any
stock dividend, stock split or combination with respect to such share after the Filing Date) (the “Series C Original Issue Price”) for each share of Series C Preferred Stock held by them, plus an additional amount equal to any
dividends declared but unpaid on each such share, and (iv) $1.1219 per share (as adjusted for any stock dividend, stock split or combination with respect to such share after the Filing Date) (the “Series D Original Issue
Price”) for each share of Series D Preferred Stock held by them, plus an additional amount equal to any dividends declared but unpaid on each such share. If, upon such liquidation, dissolution or winding up, the assets and funds distributed
are insufficient to permit the payment to each holder of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock of the full aforesaid preferential amounts, the entire assets and funds legally
available for distribution shall be distributed ratably to such holders in proportion to the preferential amount each such holder is otherwise entitled to receive with respect to the shares of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock held by such holder. The Series A Original Issue Price, Series B Original Issue Price, Series C Original Issue Price, Series D Original Issue Price and Series E Original Issue Price are sometimes
referred to herein as the “Original Issue Price.” 

  
 -3-

 (B) Remaining Assets. Upon the completion of the distribution required by subsection
(A) of this Section 4.2, the Corporation’s remaining assets or funds available for distribution to stockholders shall be distributed ratably to the holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock, Series D Preferred Stock, Series E Preferred Stock and Common Stock, on a pari passu basis, based on the number of shares of Common Stock held by each such holder (assuming full conversion of each series of Preferred Stock) until
(i) with respect to the holders of Series A Preferred Stock, such holders shall have received an aggregate of $1.07 per share (as adjusted for any stock dividend, stock split or combination with respect to such share and including amounts paid
pursuant to subsection (A) of this Section 4.2), (ii) with respect to the holders of Series B Preferred Stock, such holders shall have received an aggregate of $1.534 per share (as adjusted for any stock dividend, stock split or
combination with respect to such share and including amounts paid pursuant to subsection (A) of this Section 4.2), (iii) with respect to the holders of Series C Preferred Stock, such holders shall have received an aggregate of $1.908
per share (as adjusted for any stock dividend, stock split or combination with respect to such share and including amounts paid pursuant to subsection (A) of this Section 4.2), (iv) with respect to the holders of Series D Preferred
Stock, such holders shall have received an aggregate of $2.2438 per share (as adjusted for any stock dividend, stock split or combination with respect to such share and including amounts paid pursuant to subsection (A) of this Section 4.2)
and (v) with respect to the holders of Series E Preferred Stock, such holders shall have received an aggregate of $3.7635 per share (as adjusted for any stock dividend, stock split or combination with respect to such share and including amounts
paid pursuant to subsection (A) of this Section 4.2). After the payment or setting aside for payment to the holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E
Preferred Stock of the full amounts specified in this Section 4.2(B), the entire remaining assets of the Corporation legally available for distribution shall be distributed ratably to holders of the Common Stock of the Corporation in proportion
to the number of shares of Common Stock held by them. 
 (C) Notwithstanding subsections (A) and (B) of this
Section 4.2, solely for purposes of determining the amount each holder of shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock is entitled to receive with
respect to a liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, each series of Preferred Stock shall be treated as if all holders of such series had converted such holders’ shares of Preferred Stock into
shares of Common Stock immediately prior to such liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, if, as a result of an actual conversion of such series of Preferred Stock (including taking into account the
operation of subsection (B) of this Section 4.2 with respect to all Preferred Stock), holders of such series of Preferred Stock would receive (with respect to the shares of such series of Preferred Stock), in the aggregate, an amount
greater than the amount that would be distributed to holders of such series of Preferred Stock if such holders had not converted such shares of Preferred Stock into shares of Common Stock. If shares of any series of Preferred Stock are converted to
Common Stock or are treated as if they had been converted into Common Stock pursuant to this subsection, then holders of such series of Preferred Stock shall not be entitled to receive any distributions pursuant to subsections (A) and
(B) of this Section 4.2 that would otherwise be made to holders of such series of Preferred Stock. 

  
 -4-

 (D) (1) Unless otherwise determined by the holders of (i) a majority of the Series E
Preferred Stock, voting as a separate series and (ii) a majority of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock then outstanding, voting together as a single class on an
as-converted basis for the purposes of this Section 4.2, a liquidation, dissolution or winding up of the Corporation shall be deemed to include (Y) the acquisition of the Corporation by another entity by means of any transaction or series
of related transactions (including, without limitation, any merger, consolidation or other form of reorganization in which outstanding shares of the Corporation are exchanged for securities or other consideration issued, or caused to be issued, by
the acquiring entity or its subsidiary, but excluding any transaction effected primarily for the purpose of changing the Corporation’s jurisdiction of incorporation) that results in the transfer or acquisition of at least a majority of the
Corporation’s voting power to such entity, or (Z) a sale of all or substantially all of the assets of the Corporation or the exclusive license of all or substantially all of the Corporation’s intellectual property by means of any
transaction or series of related transactions (collectively, a “Deemed Liquidation”). 
 (2) If any assets of
the Corporation distributed to stockholders in connection with any liquidation, dissolution or winding up of the Corporation are other than cash, then the value of such assets shall be their fair market value as determined in good faith by the
Corporation’s Board of Directors; provided, however, any publicly-traded securities shall be valued as follows: 

(a) If the securities are then traded on a national securities exchange, then the value of the securities shall be deemed to be the
average of the closing prices of the securities on such exchange over the ten (10) trading day period ending five (5) trading days prior to the distribution; and 
 (b) If the securities are actively traded over-the-counter, then the value of the securities shall be deemed to be the average of the closing bid prices of the securities over the ten (10) trading
day period ending five (5) trading days prior to the distribution. 
 The foregoing methods for valuing non-cash consideration to be
distributed in connection with any liquidation, dissolution or winding up of the Corporation shall, with the appropriate approval of the definitive agreements governing such liquidation, dissolution or winding up of the Corporation by the
stockholders under the DGCL and this subsection (D), be superseded by the determination of such value set forth in the definitive agreements governing such liquidation, dissolution or winding up of the Corporation. 

(3) The Corporation shall give each holder of record of Preferred Stock written notice of a transaction described in subsection (D)(1)
not later than twenty (20) days prior to the stockholders’ meeting called to approve such transaction, or twenty (20) days prior to the closing of such transaction, whichever is earlier, and shall also notify such holders in writing
of the final approval of such transaction. The first of such notices shall describe the material terms and conditions of the impending transaction and the provisions of this Section 4.2, and the Corporation shall thereafter give such holders
prompt notice of any material changes. The transaction shall in no event take place sooner than twenty (20) days after the Corporation has given the first notice provided for herein or sooner than ten (10) days after the Corporation has
given notice of any material changes provided for herein; provided, however, that, subject to compliance with the DGCL, all notice periods set forth in this subsection (D)(3) may be shortened or waived entirely, either prospectively or
retroactively and either generally or in a particular instance, upon the written consent of the holders of a majority of the shares of Preferred Stock then outstanding (voting together as a single class, on an as-converted basis). 

  
 -5-

 (4) In the event the requirements of this subsection (D) are not complied with, the
Corporation shall forthwith either: 
 (a) Cause the closing of the Deemed Liquidation to be postponed until such time as the
requirements of this Section 4.2 have been complied with, or 
 (b) Cancel such transaction, in which event the rights,
preferences, privileges and restrictions of the holders of the Preferred Stock shall revert to and be the same as such rights, preferences, privileges and restrictions existing immediately prior to the date of the first notice referred to in
subsection (D)(3). 
 4.3 Conversion. The holders of Preferred Stock have conversion rights as follows: 

(A) Right to Convert. Each share of each series of Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Issue Price for such series of Preferred Stock by the Conversion Price for such
series of Preferred Stock, determined as hereinafter provided, in effect at the time of the conversion (the “Conversion Rate”). The initial “Conversion Price” per share for the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall be the Series A Original Issue Price, the Series B Original Issue Price, the Series C Original Issue Price, the Series D Original Issue Price and
the Series E Original Issue Price, respectively. Such initial Conversion Price for each series of Preferred Stock shall be subject to adjustment as provided in subsection (D) of this Section 4.3. 

(B) Automatic Conversion. 
 (1) Each share of each series of Preferred Stock shall automatically be converted into fully paid and nonassessable shares of Common Stock at its then effective Conversion Rate immediately prior to the
closing of a firm commitment underwritten public offering pursuant to an effective registration statement on Form S-l under the Securities Act of 1933, as amended (the “Securities Act”), covering the offer and sale of Common Stock
to the public for the account of the Corporation in which the aggregate gross proceeds to the Corporation equal or exceed $50,000,000 (a “Qualified IPO”). 
 (2) Each share of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall automatically be converted into fully paid and nonassessable shares of
Common Stock at its then effective Conversion Rate on the date specified by written consent or agreement of the holders of a majority of the then outstanding shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, voting together as a single class on an as-converted basis, delivering written notice of such election to the Company. No series of Preferred Stock listed under this subsection (2) shall be automatically converted
pursuant to this Section 4.3(B), unless all series of Preferred Stock listed under subsection (2) then outstanding shall be automatically converted into Common Stock, at the applicable Conversion Rate. 

  
 -6-

 (3) Each share of Series E Preferred Stock shall automatically be converted into fully paid
and nonassessable shares of Common Stock at its then effective Conversion Rate on the date specified by written consent or agreement of the holders of a majority of the then outstanding Series E Preferred Stock, voting as a separate series, by
delivering written notice of such election to the Company (each of the events causing conversion referred to in (1), (2) and (3) are referred to herein as an “Automatic Conversion Event”). 

(C) Mechanics of Conversion. 
 (1) Before any holder of Preferred Stock shall be entitled to convert the same into shares of Common Stock pursuant to Section 4.3(A) above, such holder shall surrender the certificate or
certificates therefor, duly endorsed, or an affidavit of loss in a form reasonably acceptable to the Corporation, at the office of the Corporation or of any transfer agent for such Preferred Stock, and shall give written notice to the Corporation at
such office that such holder elects to convert the same and shall state therein the name or names in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of surrender of the shares of Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such shares of Common Stock on such date; provided, however, that on the date of an Automatic Conversion Event, the outstanding shares of Preferred Stock to be converted in such Automatic Conversion
Event shall be converted automatically without any further action by the holders of such shares and each holder of record of shares of Preferred Stock shall be deemed on such date to be the holder of record of the Common Stock issuable upon such
conversion, whether or not (i) the certificates representing such shares are surrendered to the Corporation or its transfer agent, (ii) notice from the Corporation shall have been received by any holder of record of shares of Preferred
Stock, or (iii) the certificates evidencing such shares of Common Stock shall not then be actually delivered to such holder; provided further, however, that the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such Automatic Conversion Event unless either the certificates evidencing such shares of Preferred Stock are delivered to the Corporation or its transfer agent as provided above, or the holder notifies the
Corporation or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates.
The Corporation shall, as soon as practicable after such delivery, or after such agreement and indemnification, issue and deliver at such office to such holder of Preferred Stock, a certificate or certificates for the number of shares of Common
Stock to which the holder shall be entitled as aforesaid and a check payable to the holder in the amount of any cash amounts payable as the result of a conversion into fractional shares of Common Stock, plus any declared and unpaid dividends on the
converted Preferred Stock. 

  
 -7-

 (2) If the conversion is in connection with an underwritten offer of securities registered
pursuant to the Securities Act or a merger, sale, financing, or liquidation of the Corporation or other event, the conversion may, at the option of any holder tendering Preferred Stock for conversion, be conditioned upon the closing of such
transaction or upon the occurrence of such event, in which case the person(s) entitled to receive the Common Stock issuable upon such conversion of the Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately
prior to the closing of such transaction or the occurrence of such event. 
 (D) Adjustment of Conversion Price. The
Conversion Price for each series of Preferred Stock shall be subject to adjustment from time to time as follows: 
 (1)
(a) If the Corporation shall issue, after the Filing Date, any Additional Stock (as defined in subsection (D)(2)) without consideration or for a consideration per share less than the Conversion Price for any series of Preferred Stock in effect
immediately prior to the issuance of such Additional Stock, then (A) with respect to the Series A Preferred Stock, Series B Preferred Stock, Series D Preferred Stock and Series E Preferred Stock, the Conversion Price for such series in effect
immediately prior to each such issuance of Additional Stock shall forthwith (except as otherwise provided in this subsection (1)) be adjusted to a price equal to (calculated to the nearest one one-hundredth of one cent) the product obtained by
multiplying the Conversion Price for such series of Preferred Stock in effect immediately prior to such issuance of Additional Stock by a fraction, the numerator of which is equal to the sum of (x) the total number of shares of Common Stock
outstanding (including any shares of Common Stock deemed to be issued pursuant to subsection (D)(l)(e)(i) and (ii) of this Section 4.3) immediately prior to such issuance of Additional Stock plus (y) the number of shares of Common
Stock that the aggregate consideration received by this Corporation for such issuance of Additional Stock would purchase at the Conversion Price for such series of Preferred Stock in effect immediately prior to such issuance of Additional Stock, and
the denominator of which is equal to the sum of (x) the total number of shares of Common Stock outstanding (including any shares of Common Stock deemed to be issued pursuant to subsection (D)(l)(e)(i) and (ii) of this Section 4.3)
immediately prior to such issuance of Additional Stock plus (y) the number of shares of Additional Stock issued and (B) with respect to the Series C Preferred Stock, the Conversion Price for such series in effect immediately prior to each
such issuance of Additional Stock shall forthwith (except as otherwise provided in this subsection (1)) be adjusted to a price equal to the price paid per share for such Additional Stock, unless the price paid per share of such Additional Stock
is less than the Series B Original Issue Price, in which case the Conversion Price of the Series C Preferred Stock shall be adjusted to a price equal to the Conversion Price of the Series B Preferred Stock as determined in clause (A) of this
subsection (D)(1)(a). 
 (b) No adjustment in the Conversion Price for any series of Preferred Stock need be made if such
adjustment would result in a change in the Conversion Price of less than $0.01. Any adjustment of less than $0.01 that is not made shall be carried forward and shall be made at the time of and together with any subsequent adjustment that, on a
cumulative basis, amounts to an adjustment of $0.01 or more in the Conversion Price. Except to the limited extent provided for in subsections (D)(l)(e)(iii) or (iv), no adjustment of the Conversion Price for any series of Preferred Stock pursuant to
this subsection (D)(1) shall have the effect of increasing such Conversion Price above the Conversion Price in effect immediately prior to such adjustment. 

  
 -8-

 (c) In the case of the issuance of Additional Stock for cash, the consideration shall be
deemed to be the amount of cash paid therefor before deducting any discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. 

(d) In the case of the issuance of Additional Stock for a consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as determined in good faith by the Corporation’s Board of Directors (including each of the Preferred Directors (as such term is defined in Section 4.5(C)) irrespective of any accounting
treatment. 
 (e) In the case of the issuance (whether before, on or after the Filing Date) of (i) options to purchase or
rights to subscribe for Common Stock, (ii) securities by their terms convertible into or exchangeable for Common Stock or (iii) options to purchase or rights to subscribe for securities by their terms convertible into or exchangeable for
Common Stock, the following provisions shall apply for all purposes of subsections (D)(1) and (2): 
 (i) The aggregate maximum
number of shares of Common Stock deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) of such
options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subsections
(D)(1)(c) and (D)(1)(d)), if any, received by the Corporation upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution adjustments) for the
Common Stock covered thereby. 
 (ii) The aggregate maximum number of shares of Common Stock deliverable upon conversion of or
in exchange (assuming the satisfaction of any conditions to convertibility or exchangeability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) for any such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Corporation (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise
of any related options or rights (the consideration in each case to be determined in the manner provided in subsections (D)(1)(c) and (D)(1)(d)). 
 (iii) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon exercise of such options or rights or upon conversion of or
exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Conversion Price for each series of Preferred Stock, to the extent in any way affected by or
computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options
or rights or the conversion or exchange of such securities. 

  
 -9-

 (iv) Upon the expiration of any such options or rights, the termination of any such rights
to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price for each series of Preferred Stock, to the extent in any way affected by or computed using such options,
rights or securities or options or rights related to such securities, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issued upon
the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities. 
 (v) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to subsections (D)(l)(e)(i) and (ii) shall be appropriately adjusted to reflect any change,
termination or expiration of the type described in either subsection (D)(l)(e)(iii) or (iv). 
 (2) “Additional
Stock” shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to subsection (D)(1)(e) of this Section 4.3) by the Corporation after the Filing Date other than: 

(a) Shares of Common Stock or Common Stock Equivalents issued pursuant to an event or transaction described in subsection (D)(3) of this
Section 4.3; 
 (b) Shares of Common Stock issued or issuable upon conversion of any series of Preferred Stock, or as
dividends or distributions on any series of Preferred Stock; 
 (c) Shares of Common Stock issued (or deemed to have been issued
pursuant to subsection (D)(1)(e) of this Section 4.3) to the Corporation’s employees, officers, directors, consultants, advisors or services providers or for charitable purposes pursuant to and in accordance with Corporations 2005 Stock
Plan or any other plan, agreement or similar arrangement approved by the Corporation’s Board of Directors, provided such issuance is approved by the Corporation’s Board of Directors; 

(d) Shares of Common Stock issued (or deemed to have been issued pursuant to subsection (D)(1)(e) of this Section 4.3) to vendors,
banks or equipment lessors, provided such issuance is approved by the Corporation’s Board of Directors with such approval including at least two (2) of the Preferred Directors and is primarily for non-equity financing purposes; 

(e) Shares of Common Stock issued (or deemed to have been issued pursuant to subsection (D)(1)(e) of this Section 4.3) in connection
with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships, provided such issuance is approved by the Corporation’s Board of Directors with such approval
including at least two (2) of the Preferred Directors and is primarily for nonequity financing purposes; 

  
 -10-

 (f) Shares of Common Stock issued (or deemed to have been issued pursuant to subsection
(D)(1)(e) of this Section 4.3) in connection with a bona fide business acquisition of or by the Corporation (whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise), provided such acquisition is approved by the
Corporation’s Board of Directors with such approval including at least two (2) of the Preferred Directors; or 
 (g)
Shares of Common Stock issued in a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act pursuant to which all outstanding shares of each series of Preferred Stock are converted to
Common Stock. 
 (3) Subdivision, etc. In the event the Corporation should at any time or from time to time after the
Filing Date, fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares
of Common Stock or Common Stock Equivalents without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price for each series of Preferred Stock shall be appropriately decreased so that the number
of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents.

 (4) Combination. If the number of shares of Common Stock outstanding at any time after the Filing Date is decreased
by a combination of the outstanding shares of Common Stock, then, on the effective date of such combination, the Conversion Price for each series of Preferred Stock shall be appropriately increased so that the number of shares of Common Stock
issuable on conversion of any shares of Preferred Stock shall be decreased in proportion to such decrease in outstanding shares. 
 (E) Other Distributions. In the event the Corporation shall declare a distribution payable in securities of other persons, evidences of indebtedness issued by the Corporation or other persons,
assets (excluding cash dividends) or options or rights not referred to in subsection (D)(3) of this Section 4.3, then, in each such case for the purpose of this subsection (E), the holders of Preferred Stock shall be entitled to a proportionate
share of any such distribution as though they were the holders of the number of shares of Common Stock of the Corporation into which their respective shares of Preferred Stock are convertible as of the record date fixed for the determination of the
holders of Common Stock of the Corporation entitled to receive such distribution. 
 (F) Recapitalizations. If, at any
time or from time to time after the Filing Date there shall be a recapitalization of the Corporation’s Common Stock (other than (x) a subdivision or combination provided for in subsections (D)(3) or (D)(4) of this Section 4.3 or
(y) a Deemed Liquidation as defined in Section 4.2(D)(1)) provision shall be made so that the holders of each series of Preferred Stock shall thereafter be entitled to receive upon conversion of each such series of Preferred Stock the
number of shares of stock or other securities or property of the Corporation or 

  
 -11-

 otherwise, to which a holder of Common Stock deliverable upon conversion of such series of Preferred Stock
would have been entitled on such recapitalization. In any such case appropriate adjustment shall be made in the application of the provisions of this Section 4.3 with respect to the rights of the holders of each series of Preferred Stock after
the recapitalization to the end that the provisions of this Section 4.3 (including adjustment of the Conversion Price then in effect and the number of shares issuable upon conversion of each series of Preferred Stock) shall be applicable after
that event as nearly equivalent as prior to that event as may be practicable. 
 (G)No Impairment. The Corporation will
not, by amendment of its Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4.3 and in the taking of all such
action as may be necessary or appropriate in order to protect the conversion rights of the holders of each series of Preferred Stock set forth in this Section 4.3 against impairment. Notwithstanding the foregoing, any action taken with the
requisite stockholder consent pursuant to the terms of the Restated Certificate or the DGCL shall not be deemed to be an impairment. 
 (H)No Fractional Shares and Certificate as to Adjustment. 
 (1) No
fractional shares shall be issued upon the conversion of any share of any series of Preferred Stock and, in lieu of any fractional shares to which any holder of Preferred Stock would otherwise be entitled, the Corporation shall pay cash equal to
such fraction multiplied by the fair market value of a share of Common Stock on the date of conversion as determined in good faith by a majority of the Board of Directors. Whether or not fractional shares are issuable upon such conversion shall be
determined on the basis of the total number of shares of Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. 

(2) Upon the occurrence of each adjustment or readjustment of the Conversion Rate for any series of Preferred Stock pursuant to this
Section 4.3, the Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of such series of Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon written request at any time of any holder of any series of Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (i) all such adjustments and readjustments, (ii) the Conversion Rate at the time in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property that
at the time would be received upon the conversion of such holder’s shares of Preferred Stock. 
 (I) Notices of Record
Date. In the event of any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other
distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property or to receive any other right, the Corporation shall mail to each holder of Preferred Stock 

  
 -12-

 at least fifteen (15) business days prior to such record date, a notice specifying the date on which
any such record is to be taken for the purpose of such dividend or distribution or right, and the amount and character of such dividend, distribution or right; provided, however, that, subject to compliance with the DGCL, all notice periods
set forth in this subsection (I) may be shortened or waived entirely, either prospectively or retroactively and either generally or in a particular instance, upon the written consent of the holders of a majority of the shares of Preferred Stock
then outstanding (voting together as a single class, on an as-converted basis). 
 (J) Reservation of Stock Issuable Upon
Conversion. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock solely for the purpose of effecting the conversion of the shares of Preferred Stock such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the
conversion of all then outstanding shares of Preferred Stock, the Corporation will take such corporate action as may, based upon advice of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purpose, including, without limitation, engaging commercially reasonable efforts to obtain the requisite stockholder approval for any necessary amendment to these Restated Certificate. 

(K) Special Mandatory Conversion. 
 (1) In the event that: 
 (a) the Corporation consummates one or more sales of its
equity securities (each, a “Financing”) after the date that the Corporation first issues shares of Series E Preferred Stock (the “Series E Original Issue Date”) and: 

(i) following the approval and determination that such Financing shall constitute a Mandatory Offering (as defined below) by the
Corporation’s Board of Directors (with such approval including at least two (2) of the Preferred Directors), the Corporation shall have delivered a notice (“Notice”) to each holder of at least 1,000,000 shares (as adjusted
for any stock dividend, stock split or combination with respect to such shares) of Preferred Stock and any of their transferees or assignees of Preferred Stock (each, a “Major Holder”): (1) stating the Corporation’s bona
fide intention to consummate the Financing, (2) indicating the aggregate number of securities to be offered in the Financing and the number of such securities to be offered to the Major Holders, as determined by the Corporation’s Board of
Directors in its sole discretion, (3) indicating the price and terms upon which it proposes to offer such securities, (4) identifying the Pro Rata Share (as defined below) of each Major Holder, and (5) offering each Major Holder the
right to purchase such Major Holder’s Pro Rata Share within the time periods set forth in the Notice; 
 (ii) at least one
(1) of the Major Holders participates in the Financing (a Financing that meets each of the requirements set forth in subsections (i) and (ii) of this subsection (K)(l)(a), a “Mandatory Offering”) in a portion not less
than such Major Holder’s full Pro Rata Share; and 

  
 -13-

 (iii) a Major Holder does not acquire or cause an affiliate or partner of such Major Holder
to acquire at least its Pro Rata Share within the time periods set forth in the Notice (a “Non-Participating Major Holder”); 
 (b) then a percentage of each Non-Participating Major Holder’s shares of each series of Preferred Stock equal to the percentage of such Non-Participating Major Holder’s Pro Rata Share not
acquired by such Non-Participating Major Holder shall automatically and without further action on the part of such holder be converted, effective upon, subject to, and concurrently with, the consummation of the Mandatory Offering (the
“Mandatory Offering Date”), into shares of Common Stock of the Corporation at the Conversion Rate in effect for such shares immediately prior to, and without giving effect to any adjustment to such Conversion Rate that may otherwise
occur as a result of, the Mandatory Offering. For purposes of this Section 4.3(K), each Major Holder’s “Pro Rata Share” shall be an amount determined by multiplying the aggregate number of equity securities to be offered
to the Major Holders as specified in the Notice by a fraction, the numerator of which shall be the number of shares of Common Stock then issued or issuable upon conversion of the Preferred Stock (and all securities convertible into, or exercisable
or exchangeable for shares of Preferred Stock) then held by such Major Holder and the denominator of which shall be the total number of shares of Common Stock then issued or issuable upon conversion of the Preferred Stock (and all securities
convertible into, or exercisable or exchangeable for shares of Preferred Stock) then held by all Major Holders. For purposes of calculating a Major Holder’s Pro Rata Share, the applicable number of shares of Common Stock then issued or issuable
upon conversion of the Preferred Stock shall be calculated based on the number of shares of Preferred Stock (and all securities convertible into, or exercisable or exchangeable for shares of Preferred Stock) outstanding immediately prior to the
closing of, and without giving effect to any adjustment to such Conversion Rate that may otherwise occur as a result of, the Mandatory Offering. 
 (2) The holder of any shares of any series of Preferred Stock converted pursuant to this Section 4.3(K) shall deliver to the Corporation during regular business hours at the office of any transfer
agent of the Corporation for the Preferred Stock, or at such other place as may be designated by the Corporation, the certificate or certificates for the shares so converted, duly endorsed or assigned in blank or to the Corporation. As promptly as
practicable thereafter, the Corporation shall issue and deliver to such holder, at the place designated by such holder, a certificate or certificates for the number of full shares of Common Stock to be issued and such holder shall be deemed to have
become a stockholder of record of Common Stock on the Mandatory Offering Date, unless the transfer books of the Corporation are closed on that date, in which event such holder shall be deemed to have become a stockholder of record of Common Stock on
the next succeeding date on which the transfer books are open. 
 (3) Notwithstanding the foregoing, paragraphs (1) and
(2) of this Section 4.3(K) shall not apply to Starent Networks LLC, Cisco Systems, Inc., or any of their respective affiliates. 

  
 -14-

 (L) Waiver of Adjustment of Conversion Price. The holders of a majority of the Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock then outstanding, voting as a single class on an as-converted basis (which determination may be either prospective or retroactive and either generally
or in a particular instance, and shall bind all future holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock) may waive the rights provided by subsection (D) of this
Section 4.3 with respect to the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock. The holders of a majority of the Series E Preferred Stock then outstanding (which determination may be
either prospective or retroactive and either generally or in a particular instance, and shall bind all future holders of Series E Preferred Stock) may waive the rights provided by subsection (D)of this Section 4.3 with respect to the Series E
Preferred Stock. 
 4.4 Redemption. 

(A) Right to Redemption. Upon receipt of a written request from the holders of a majority of the then
outstanding shares of (x) Series E Preferred Stock, voting as a separate series, and (y) Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, voting together as a single class (the
“Redemption Request”), at any time on or after the fourth (4th) anniversary of the Series E Original Issue Date, the Corporation shall redeem all, but not less than all, of the shares of Preferred Stock then outstanding in three (3) equal annual
installments (each installment date, a “Redemption Date”), commencing on a date not more than forty five (45) days after the receipt of the Redemption Request, for a price per share equal to the appropriate Original Issue Price
plus any declared and unpaid dividends per share for such series of Preferred Stock (the “Redemption Price”). On each Redemption Date, the Corporation shall redeem, on a pro rata basis in accordance with the number of shares of each
series of Preferred Stock owned by each holder (except as set forth in this Section 4.4(A)), that number of outstanding shares of each series of Preferred Stock determined by dividing (i) the total number of shares of such series of
Preferred Stock outstanding immediately prior to such Redemption Date by (ii) the number of remaining Redemption Dates (including the Redemption Date to which such calculation applies) (such number, the “Eligible Shares” in
respect of such series). The Corporation shall on each such Redemption Date redeem up to the maximum amount the Corporation may lawfully redeem out of funds legally available therefore in accordance with subsection (B) of this Section 4.4.
If on any Redemption Date, the number of shares of Preferred Stock that may then be legally redeemed by the Corporation is less than the number of such shares to be redeemed, then all of the Eligible Shares of Series E Preferred Stock in respect of
such Redemption Date shall be redeemed for the applicable Redemption Price prior to the redemption of the Eligible Shares of any other series of Preferred Stock in respect of such Redemption Date and then the remaining Eligible Shares that should
have been redeemed in respect of such Redemption Date, but were not, will be redeemed on a pro rata basis from any additional legally available funds or as soon as the Corporation has legally available funds therefor. 

(B) Redemption Procedure. Subject to subsection (A) of this Section 4.4, within fifteen (15) days of the receipt by
the Corporation of the Redemption Request, with respect to the first Redemption Date, and not less than thirty (30) days prior to the second and third Redemption Dates, the Corporation shall mail, first class postage prepaid, written notice
(the “Notice of Redemption”) to each holder of record (at the close of business on the business day preceding the day on which notice is given) of Preferred Stock, at the address last shown on the records of the Corporation for such
holder or given by the holder to the Corporation, for the purpose of notifying such holder of the redemption to be effected. The Notice of Redemption shall specify the applicable 

  
 -15-

 
Redemption Date, the number of shares of each series of Preferred Stock held by the holder that the Corporation shall redeem on the Redemption Date specified in the Notice of Redemption, and the
place at which payment shall be made, which shall be the principal offices of the Corporation or such other place as shall be mutually agreeable to the Corporation and holders of a majority of the shares of Preferred Stock then outstanding, on an
as-converted basis. The Notice of Redemption shall call upon each holder of Preferred Stock to either (i) surrender to the Corporation, in the manner and at the place designated, such holder’s certificate or certificates representing the
shares to be redeemed or (ii) convert such Preferred Stock into Common Stock prior to the applicable Redemption Date in accordance with the provisions of Section 4.3 above. Subject to Section 4.4 (C), on each Redemption Date, the
Corporation shall pay the Redemption Price in cash or by check to the order of the person whose name appears on the certificate or certificates of the Preferred Stock that (i) shall not have been converted pursuant to Section 4.3 hereof
and (ii) shall have been surrendered to the Corporation in the manner and at the place designated in the Notice of Redemption and thereupon each surrendered certificate shall be canceled. 

(C) Effect of Redemption. From and after each Redemption Date, unless there shall have been a default in payment of the Redemption
Price, all rights of the holders of the shares of any series of Preferred Stock to be redeemed on a Redemption Date (except the right to receive their respective Redemption Price without interest upon surrender of their certificate or certificates)
shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. Subject to the last sentence of Section 4.4(A), if the funds
of the Corporation legally available for redemption on any Redemption Date are insufficient to redeem the total number of shares requested to be redeemed on such date, those funds which are legally available will be used to redeem the maximum
possible number of such shares ratably among the holders of such shares to be redeemed based upon the proceeds to be received by them pursuant to this Section 4.4. The shares not redeemed shall remain outstanding and be entitled to all the
rights and preferences provided herein. At any time and from time to time thereafter when additional funds of the Corporation are legally available for the redemption of shares not redeemed, such funds will immediately be irrevocably (subject to
such funds becoming legally unavailable for distribution) set aside for the redemption of the balance of the shares which the Corporation has become obligated to redeem on any Redemption Date but which it has not redeemed. 

4.5 Voting. 
 (A) General. Each holder of each outstanding share of each series of Preferred Stock shall be entitled to the number of votes equal to the number of whole shares of Common Stock into which the
shares of Preferred Stock held by such holder are then convertible (as adjusted from time to time pursuant to Section 4.3 hereof) at each meeting of stockholders of the Corporation (and pursuant to written consent of stockholders in lieu of
meetings) with respect to any and all matters presented to the stockholders of the Corporation for their action or consideration. Except as provided by law or by the provisions of this Section 4.5 or by Section 4.6 below, holders of Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall vote together with the holders of Common Stock as a single class on all actions to be taken by the stockholders of the
Corporation, including, but not limited to actions amending this Restated Certificate to increase the number of authorized shares of Common Stock. Fractional votes shall not, however, be permitted and any fractional voting resulting from the above
formula (after aggregating all shares into which shares of Preferred Stock held by each holder could be converted) shall be rounded down to the nearest whole number. 

  
 -16-

 (B) Adjustment in Authorized Common Stock. Without limiting the generality of
Section 4.5(A), and in accordance with the provisions of Section 242(b)(2) of the DGCL, the number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares of Common Stock then outstanding) by
the affirmative vote of the holders of a majority of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Common Stock, voting together as one class and not as separate
classes or series, with each holder of Preferred Stock having that number of votes per share as is equal to the number of shares of Common Stock into which each such share of Preferred Stock held by such holder could be converted on the date for
determination of stockholders entitled to vote on such increase or decrease. 
 (C) Election of Directors. 

. (1) The holders of Common Stock, voting as a single class, shall be entitled to elect two (2) members of the
Corporation’s Board of Directors at each meeting or pursuant to each written consent of the Corporation’s holders of Common Stock for the election of directors (the “Common Directors”). The holders of Series A Preferred
Stock shall be entitled to elect two (2) members of the Corporation’s Board of Directors at each meeting or pursuant to each written consent of the Corporation’s holders of Series A Preferred Stock for the election of directors (the
“Series A Directors”). The holders of Series B Preferred Stock shall be entitled to elect one (1) member of the Corporation’s Board of Directors at each meeting or pursuant to each written consent of the Corporation’s
holders of Series B Preferred Stock for the election of directors (the “Series B Director,”). The holders of Series E Preferred Stock shall be entitled to elect one (1) member of the Corporation’s Board of Directors at
each meeting or pursuant to each written consent of the Corporation’s holders of Series E Preferred Stock for the election of directors (the “Series E Director,” and together with the Series A Directors and the Series B
Director, the “Preferred Directors”). The holders of a majority of the then outstanding Preferred Stock and Common Stock, voting together as a single class and on an as-converted basis, shall be entitled to elect the remaining
members of the Corporation’s Board of Directors at each meeting or pursuant to each written consent of the Corporation’s stockholders for the election of directors. 
 (2) Whenever the holders of any class or classes of stock or series thereof are entitled to elect one or more directors by Section 4.5(C)(1), vacancies and newly created directorships of such class
or classes or series may be filled by at least a majority of the directors elected by such class or classes or series thereof then in office, or by a sole remaining director so elected, or, if there is no sole remaining director then in office, by
the affirmative vote of the holders of at least a majority of the shares of that class or classes or series. 
 (3) Any
director who was elected by a specified class or classes of stock or series thereof may be removed during his or her term of office, either for or without cause, by, and only by, the affirmative vote of the holders of at least a majority of the
shares of the class or classes of stock or series thereof that are entitled to elect such director. Such vote may be given at a special meeting of such stockholders duly called or by an action by written consent for that purpose.

 EXHIBIT C 
 LOCK-UP AGREEMENTEX-10.1

 Exhibit 10.1 
 MAVENIR SYSTEMS, INC. 
 INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is effective as of
[            , 20        ], by and between Mavenir Systems, Inc., a Delaware corporation (the “Company”), and
[            ] (“Indemnitee”). 
 A. The
Company recognizes the continued difficulty in obtaining liability insurance for its directors, officers, employees, controlling persons, fiduciaries and other agents and affiliates, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance. 
 B. The Company further recognizes the substantial increase in corporate
litigation in general, subjecting directors, officers, employees, controlling persons, fiduciaries and other agents and affiliates to expensive litigation risks at the same time as the availability and coverage of liability insurance has been
severely limited. 
 C. The current protection available to directors, officers, employees, controlling persons, fiduciaries and
other agents and affiliates of the Company may not be adequate under the present circumstances, and directors, officers, employees, controlling persons, fiduciaries and other agents and affiliates of the Company (or persons who may be alleged or
deemed to be the same), including Indemnitee, may not be willing to continue to serve or be associated with the Company in such capacities without additional protection. 
 D. The Company (a) desires to attract and retain the involvement of highly qualified persons, such as Indemnitee, to serve and be associated with the Company and, accordingly, (b) wishes to
provide for the indemnification and advancement of expenses to Indemnitee to the maximum extent permitted by applicable law. 

E. In view of the considerations set forth above, the Company desires that Indemnitee shall be indemnified and advanced expenses by the
Company as set forth herein. 
 In consideration of the mutual promises and covenants contained herein, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Definitions. 

(a) “Bylaws” means the Company’s Bylaws as currently in effect, as hereafter amended or amended and restated
from time to time. 
 (b) “Certificate of Incorporation” means the Company’s Certificate of
Incorporation as currently in effect, as hereafter amended or amended and restated from time to time. 

 (c) “Change in Control” shall be deemed to have occurred if, on or
after the date of this Agreement, (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company acting
in such capacity or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company, becomes the “beneficial owner” (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than thirty percent (30%) of the total voting power represented by the Company’s then outstanding Voting Securities (as defined
below); (ii) during any period of two (2) consecutive years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board of Directors of the Company and any new
director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in Sections 1(c)(i), 1(c)(iii) or 1(c)(iv) herein) whose election by the Board of
Directors or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved, cease for any reason to constitute a majority thereof; (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation other than a merger or
consolidation which would result in the Voting Securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into Voting Securities of the surviving entity) at least
eighty percent (80%) of the total voting power represented by the Voting Securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or (iv) the stockholders of the Company approve a plan of
complete liquidation of the Company or an agreement for the sale or disposition by the Company of (in one transaction or a series of related transactions) all or substantially all of the Company’s assets. 

(d) “Claim” means with respect to an Indemnification Event, any threatened, asserted, pending or completed
action, suit, proceeding or alternative dispute resolution mechanism, whether brought in the right of the Company or otherwise, or any hearing, inquiry or investigation (formal or informal) that Indemnitee in good faith believes might lead to the
institution of any such action, suit, proceeding or alternative dispute resolution mechanism, whether civil, criminal, administrative, investigative or other, including any appeal therefrom. 

(e) References to the “Company” includes, in addition to Mavenir Systems, Inc., any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or merger to which the Company (or any of its wholly owned subsidiaries) is a party, which, if its separate existence had continued, would have had the power and authority to
indemnify its directors, trustees, partners, managing members, officers, employees, agents or fiduciaries, so that if Indemnitee is or was a director, trustee, partner, managing member, officer, employee, agent or fiduciary of such constituent
corporation, or is or was serving at the request of such constituent corporation as a director, trustee, partner, managing member, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust
or other enterprise, Indemnitee shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as Indemnitee would have with respect to such constituent corporation if its separate
existence had continued.

 (f) “DGCL” means the General Corporation Law of the State of
Delaware. 
 (g) “Enterprise” means the Company and any other corporation, limited liability company,

settlement of, or final judgment in, any action, suit, proceeding or alternative dispute resolution mechanism, hearing, inquiry or investigation, which constitutes a Claim. 
 (j) “Expenses” shall mean any and all direct and indirect costs, losses, claims, damages, fees, expenses and liabilities, joint or several (including attorneys’ fees and all
other costs, expenses and obligations incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to defend, to be a witness in or to participate in, any action, suit, proceeding,
alternative dispute resolution mechanism, hearing, inquiry or investigation), judgments, fines, penalties and amounts paid in settlement (if such settlement is approved in advance by the Company, which approval shall not be unreasonably withheld)

in connection with any appeal resulting from any Claim, including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent; (ii) Expenses incurred in connection
with recovery under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee is ultimately determined to be entitled to such indemnification, advancement of Expenses or insurance
recovery, as the case may be; and (iii) for purposes of Section 13(e) only, Expenses incurred by or on behalf of Indemnitee in connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement, by
litigation or otherwise. The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by
affidavit of Indemnitee’s counsel as being reasonable shall be presumed conclusively to be reasonable. 
 (k)

attorneys, selected in accordance with the provisions of Section 2(d) hereof, who shall not have otherwise performed services for (i) the Company or Indemnitee in any matter material to either such party (other than with respect to
matters concerning the rights of Indemnitee under this Agreement, or of other indemnitees under similar indemnity agreements); or (ii) any other party to the Claim giving rise to a claim for indemnification under this Agreement, within the last
three (3) years. Notwithstanding the foregoing, the term “Independent Legal Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in

to be in the interest of the participants and beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this
Agreement.

2. Indemnification.

 -4-

 (i) Subject to the provisions of Section 2(b) below, the Company shall
indemnify Indemnitee for Expenses to the fullest extent permitted by applicable law if Indemnitee was or is or becomes a party or potential party to or witness or other participant in, or is threatened to be made a party to or other participant in,
any Claim (whether by reason of or arising in part out of an Indemnification Event), including all interest, assessments and other charges incurred in connection with or in respect of such Expenses. The parties hereto intend that this Agreement
shall provide to the fullest extent permitted by applicable law for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, or by
statute, any other agreement, a vote of its stockholders or disinterested directors, or otherwise. 
 (ii) Notwithstanding any
other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of an Indemnification Event, a witness or otherwise asked to participate in any aspect of a Claim to which
Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

(b) Review of Indemnification Obligations. 
 (i) Notwithstanding the foregoing, in the event any Reviewing Party shall have determined (in a written opinion, in any case in which Independent Legal Counsel is the Reviewing Party) that Indemnitee is
not entitled to be indemnified under this Agreement under applicable law, (A) the Company shall have no further obligation under Section 2(a) to make any payments to Indemnitee not made prior to such determination by such Reviewing
Party; and (B) the Company shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company) for all Expenses theretofore paid in indemnifying Indemnitee (within thirty (30) days after the Indemnitee receives
notice of such determination); provided, however, that if Indemnitee has commenced or thereafter commences legal proceedings in a court of competent jurisdiction to secure a determination that Indemnitee is entitled to be indemnified
under this Agreement under applicable law, any determination made by any Reviewing Party that Indemnitee is not entitled to be indemnified under this Agreement under applicable law shall not be binding and Indemnitee shall not be required to
reimburse the Company for any Expenses theretofore paid in indemnifying Indemnitee unless, until and only to the extent that a final judicial determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted
or lapsed) and until such time, Indemnitee shall be entitled to receive interim payments of expenses pursuant to this Section 2. Indemnitee’s obligation to reimburse the Company for any Expenses shall be unsecured and no interest
shall be charged thereon. 
 (ii) Subject to Section 2(b)(iii) below, if the Reviewing Party shall not have made a
determination within forty-five (45) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by applicable law, be deemed to have been
made and Indemnitee shall be entitled to such indemnification, absent (A) a misstatement by Indemnitee of a material fact, or Indemnitee’s omission of a material fact necessary to make Indemnitee’s statement not materially misleading,
in connection with the request for indemnification; or (B) a prohibition of such indemnification under applicable law; provided, however, that such forty-five (45) day period may be extended for a reasonable time, not to
exceed an additional thirty (30) days, if the 

  
 -5-

 
Reviewing Party in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto. In the event that the Reviewing Party extends the
forty-five (45) day review period, the Company will provide written notice of such extension to the Indemnitee. 
 (iii)
Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final disposition of the Claim. 

(c) Indemnitee Rights on Unfavorable Determination; Binding Effect. If any Reviewing Party determines that Indemnitee
substantively is not entitled to be indemnified under this Agreement in whole or in part under applicable law, Indemnitee shall have the right to commence litigation seeking an initial determination by the court or challenging any such determination
by such Reviewing Party or any aspect thereof, including the legal or factual bases therefor, and, subject to the provisions of Section 15, the Company hereby consents to service of process and to appear in any such proceeding. Absent
such litigation, any determination by any Reviewing Party shall be conclusive and binding on the Company and Indemnitee. 
 (d)
Selection of Reviewing Party; Change in Control. If there has not been a Change in Control, any Reviewing Party shall be selected (i) by a majority vote of the directors of the Company who are not and were not a party to the Claim
in respect of which indemnification is sought by Indemnitee (“Disinterested Directors”), even if less than a quorum of the Board; (ii) by a committee of Disinterested Directors designated by a majority vote of the
Disinterested Directors, even if less than a quorum of the Board; (iii) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Legal Counsel in a written opinion to the Board, a copy of which
shall be delivered to Indemnitee; or (iv) if so directed by the Board, by the stockholders of the Company; and if there has been such a Change in Control (other than a Change in Control which has been approved by a majority of the
Company’s Board of Directors who were directors immediately prior to such Change in Control), any Reviewing Party with respect to all matters thereafter arising concerning Indemnitee’s indemnification rights for Expenses under this
Agreement or any other agreement or under the Certificate of Incorporation or Bylaws as now or hereafter in effect, or under any other applicable law, if desired by Indemnitee, shall be Independent Legal Counsel selected by Indemnitee and approved
by the Company (which approval shall not be unreasonably withheld). Such counsel, among other things, shall render its written opinion to the Company and Indemnitee as to whether and to what extent Indemnitee would be entitled to be indemnified
under this Agreement under applicable law and the Company agrees to abide by such opinion. The Company agrees to pay the reasonable fees of the Independent Legal Counsel referred to above and to fully indemnify such counsel against any and all
expenses (including attorneys’ fees), claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. Notwithstanding any other provision of this Agreement, the Company shall not be required
to pay Expenses of more than one Independent Legal Counsel in connection with all matters concerning a single Indemnitee, and such Independent Legal Counsel shall be the Independent Legal Counsel for any or all other Indemnitees unless (A) the
Company otherwise determines; or (B) any Indemnitee shall provide a written statement setting forth in detail a reasonable objection to such Independent Legal Counsel representing other Indemnitees. 

  
 -6-

 (e) Mandatory Payment of Expenses. Notwithstanding any other provision of this
Agreement other than Section 10 hereof, to the fullest extent permitted by applicable law and to the extent that Indemnitee was a party to (or participant in) and has been successful on the merits or otherwise, in any Claim or in defense
of any claim, issue or matter therein, in whole or in part, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Claim but is
successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Claim, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s
behalf in connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by applicable law. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a
Claim by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

(f) Contribution. 
 (i) To the fullest extent permitted by applicable law, if the indemnification rights provided for in this Agreement are for any reason whatsoever unavailable to an Indemnitee, then in lieu of indemnifying
Indemnitee thereunder, the Company shall contribute to the amount incurred by or on behalf of Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, including all interest,
assessments and other charges incurred in connection with or in respect of such Expenses (i) in such proportion as is deemed fair and reasonable in light of all of the circumstances in order to reflect the relative benefits received by the
Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Claim; or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and its directors, officers, employees and agents, other than Indemnitee, on the one hand, and of the Indemnitee alone, on the other hand,
in connection with the action or inaction which resulted in such Expenses, as well as any other relevant equitable considerations. In connection with any registration of the Company’s securities under any securities laws (including,
without limitation, under the Securities Act or the Exchange Act), the relative benefits received by the Company and Indemnitee shall be deemed to be in the same respective proportions that the net proceeds from the relevant registered offering(s)
(before deducting expenses) received by the Company and Indemnitee, in each case as set forth in the applicable prospectus, bear to the aggregate public offering price of the securities so offered. The relative fault of the Company and its
directors, officers, employees and agents, other than Indemnitee, on the one hand, and of the Indemnitee alone, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or its directors, officers, employees and agents, other than Indemnitee, or supplied by the Indemnitee and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (ii) The Company
and Indemnitee agree that it would not be just and equitable if contribution pursuant to this Section 2(f) were determined by pro rata or by any other method of allocation which does not take account of the equitable considerations
referred to in 

  
 -7-

 
the immediately preceding paragraph. In connection with the registration of the Company’s securities, in no event shall Indemnitee be required to contribute any amount under this
Section 2(f) in excess of the net proceeds received by Indemnitee from Indemnitee’s sale of securities under such registration statement. No person found guilty of fraudulent misrepresentation (within the meaning of Section 12
of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation. 
 3. Expense Advances. Notwithstanding any provision of this Agreement to the contrary, the Company shall make Expense Advances, to the extent not prohibited by applicable law, to an
Indemnitee in connection with any Claim (or any part of any Claim) not initiated by Indemnitee, and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement or statements requesting such advances
from time to time (which shall include invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditures made that would cause
Indemnitee to waive any privilege accorded by applicable law shall not be so included), whether prior to or after final disposition of any Claim. Expense Advances shall be unsecured and interest free. Expense Advances shall be made without regard to
Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 13(e), advances shall include any
and all Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. Indemnitee shall qualify for advances upon the
execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the amounts advanced (without interest) to the extent that it is ultimately determined that Indemnitee is
not entitled to be indemnified by the Company. No other form of undertaking shall be required other than the execution of this Agreement. This Section 3 shall not apply to any claim made by Indemnitee for which indemnity is excluded
pursuant to Section 10. 
 4. Procedures for Indemnification and Expense Advances. 

(a) Timing of Payments. All payments of Expenses by the Company to Indemnitee pursuant to this Agreement shall be made to
the fullest extent permitted by applicable law as soon as practicable after written demand by Indemnitee therefor is presented to the Company, but in no event later than forty-five (45) days after such written demand by Indemnitee is presented
to the Company, except in the case of Expense Advances, which shall be paid in accordance with Section 3 of this Agreement. If the Company disputes a portion of the amounts for which indemnification is requested, the undisputed portion
shall be paid and only the disputed portion withheld pending resolution of any such dispute. 
 (b) Notice/Cooperation by
Indemnitee. Indemnitee shall give the Company notice in writing as soon as practicable of any Claim made against Indemnitee for which indemnification or Expense Advances will or could be sought under this Agreement. Notice to

  
 -8-

 
the Company shall be directed to the President or Chief Executive Officer of the Company at the address shown on the signature page of this Agreement (or such other address as the Company shall
designate in writing to Indemnitee) and shall include a summary description of the nature of the Claim and the facts underlying the Claim, in each case to the extent reasonably known to and understood by Indemnitee. 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 following the final disposition of such Claim. In addition, Indemnitee shall give the Company such information and cooperation as it may reasonably require and as shall be within Indemnitee’s
power. The failure by Indemnitee to notify the Company under this Agreement will not relieve the Company from any liability which it may have to Indemnitee under this Agreement or otherwise than under this Agreement, and any delay in so
notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement, except to the extent (solely with respect to the indemnity under this Agreement) that such failure or delay materially prejudices the Company.

 (c) Presumptions and Effect of Certain Proceedings. 

(i) In making a determination with respect to entitlement to indemnification under this Agreement, the person or persons or entity
making such determination shall, to the fullest extent not prohibited by applicable law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with
Section 4 of this Agreement, and the Company shall, to the fullest extent not prohibited by applicable law, have the burden of proof and burden of persuasion by clear and convincing evidence to overcome that presumption in connection
with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Legal 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 directors or Independent Legal
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. 

(ii) The termination of any Claim 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 Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Claim, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.

 (iii) For purposes of any determination of good faith, 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, including financial statements, or on information supplied to Indemnitee by any of the directors or officers of the Enterprise in the course of their duties, or
on the advice of any legal counsel for the Enterprise or on information or records given or reports 

  
 -9-

 
made to the Enterprise by any independent certified public accountant or by any appraiser or other expert selected with reasonable care by the Enterprise. The provisions of this
Section 4(c) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. Whether or not the foregoing
provisions of this Section 4(c) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner Indemnitee 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. 
 (iv) The knowledge and/or actions, or failure to act, of any other director, officer, trustee, partner, managing member, fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee
for purposes of determining the right to indemnification under this Agreement. 
 (d) Notice to Insurers. If, at
the time of the receipt by the Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company has liability insurance in effect which may cover such Claim, the Company shall give prompt notice of the commencement of such
Claim to the insurers in accordance with the procedures set forth in the respective insurance policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable
as a result of such Claim in accordance with the terms of such policies. 
 (e) Selection of Counsel. In the event
the Company shall be obligated under this Agreement to provide indemnification for or make any Expense Advances with respect to the Expenses of any Claim, the Company, if appropriate, shall be entitled to assume the defense of such Claim with
counsel approved by Indemnitee (which approval shall not be unreasonably withheld) upon the delivery to Indemnitee of written notice of the Company’s election to do so. After delivery of such notice, approval of such counsel by Indemnitee and
the retention of such counsel by the Company, the Company will not be liable to Indemnitee under this Agreement for any fees or expenses of separate counsel subsequently employed by or on behalf of Indemnitee with respect to the same Claim;
provided, however, that (i) Indemnitee shall have the right to employ Indemnitee’s separate counsel in any such Claim at Indemnitee’s expense; and (ii) if (A) the employment of separate counsel by Indemnitee
has been previously authorized by the Company; (B) Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense; or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and expenses of Indemnitee’s separate counsel shall be Expenses for which Indemnitee may receive indemnification or Expense Advances under this Agreement. Subject to the
preceding terms and other terms of this Agreement, the Company shall have the right to conduct such defense as it sees fit in its sole discretion, including the right to settle any Claim against Indemnitee without the consent of Indemnitee, so long
as the terms of such settlement include either: (x) a full release of Indemnitee by the claimant from all liabilities or potential liabilities under such Claim; or (y) in the event such full release is not obtained, the terms of such
settlement do not limit any indemnification right Indemnitee may now, or hereafter, be entitled to under this Agreement, the Certificate of Incorporation, the Bylaws, any other agreement, or by statute, a vote of stockholders or disinterested
directors, the DGCL or otherwise. Notwithstanding the foregoing, the Company shall not settle any Claim in any manner that would impose any Expenses on Indemnitee without Indemnitee’s prior written consent, which consent shall not be
unreasonably withheld. 

  
 -10-

 5. Additional Indemnification Rights; Nonexclusivity.

 (a) Scope. The Company hereby agrees to indemnify Indemnitee to the fullest extent permitted by applicable law,
notwithstanding that such indemnification is not specifically authorized by the other provisions of this Agreement, the Company’s Certificate of Incorporation, the Bylaws or by statute, any other agreement, a vote of stockholders or
disinterested directors, or otherwise. The rights of indemnification and to receive Expense Advances as provided by this Agreement shall be interpreted independently of, and without reference to, any other such rights to which Indemnitee may be
entitled at any time. In the event of any change after the date of this Agreement in any applicable law, statute or rule which expands the right of a Delaware corporation to indemnify a member of its board of directors or an officer, employee, agent
or fiduciary, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits afforded by such change. In the event of any change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its board of directors or an officer, employee, agent or fiduciary, such change, to the extent not otherwise required by such applicable law, statute or rule to be applied to this Agreement, shall have
no effect on this Agreement or the parties’ rights and obligations under this Agreement except as set forth in Section 10(a) hereof. 
 (b) Nonexclusivity. The indemnification rights and the payment of Expense Advances provided by this Agreement shall be cumulative and in addition to any rights to which Indemnitee may be
entitled under the Certificate of Incorporation, the Bylaws, any other agreement, or by statute, a vote of stockholders or disinterested directors, the DGCL, or otherwise. The indemnification rights and the payment of Expense Advances provided under
this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity even though subsequent thereto Indemnitee may have ceased to serve in such capacity. 

6. No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment in connection with
any Claim made against Indemnitee to the extent Indemnitee has otherwise actually received payment (under any insurance policy, provision of the Certificate of Incorporation, the Bylaws or otherwise) of the amounts otherwise payable under this
Agreement, except as provided in Section 18 below. 
 7. Partial Indemnification. If Indemnitee is
entitled under any provision of this Agreement to indemnification by the Company for some or a portion of Expenses incurred in connection with any Claim, but not, however, for the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled. 

  
 -11-

 8. Mutual Acknowledgment. Both the Company and Indemnitee acknowledge that, in
certain instances, federal law or applicable public policy may prohibit the Company from indemnifying its directors, officers, employees, agents or fiduciaries under this Agreement or otherwise. Indemnitee understands and acknowledges that the
Company may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification rights to a court in certain circumstances for a determination of the Company’s right under public policy
to indemnify Indemnitee. 
 9. Liability Insurance. To the extent the Company maintains liability
insurance applicable to directors, officers, employees, agents or fiduciaries, Indemnitee shall be covered by such policies in such a manner as to provide Indemnitee the same rights and benefits as are provided to the most favorably insured of the
Company’s directors, if Indemnitee is a director; or of the Company’s officers, if Indemnitee is not a director of the Company but is an officer; or of the Company’s key employees, agents or fiduciaries, if Indemnitee is not an
officer or director but is a key employee, agent or fiduciary. 
 10. Exceptions. Notwithstanding
any other provision of this Agreement: 
 (a) Excluded Action or Omissions. The Company shall not be obligated
pursuant to the terms of this Agreement to indemnify Indemnitee for Expenses resulting from acts, omissions or transactions for which Indemnitee is prohibited from receiving indemnification under this Agreement or applicable law; provided, however,
that notwithstanding any limitation set forth in this Section 10(a) regarding the Company’s obligation to provide indemnification to Indemnitee, Indemnitee shall be entitled under Section 3 to receive Expense Advances
under this Agreement with respect to any such Claim unless and until a court having jurisdiction over the Claim shall have made a final judicial determination (as to which all rights of appeal therefrom have been exhausted or lapsed) that Indemnitee
has engaged in acts, omissions or transactions for which Indemnitee is prohibited from receiving indemnification under this Agreement or applicable law. 
 (b) Claims Initiated by Indemnitee. The Company shall not be obligated pursuant to the terms of this Agreement to indemnify or make Expense Advances to Indemnitee with respect to Claims
initiated or brought voluntarily by Indemnitee and not by way of defense, counterclaim or cross-claim, except (i) with respect to actions or proceedings brought to establish or enforce an indemnification or Expense Advances right under this
Agreement or any other agreement or insurance policy or under the Certificate of Incorporation or the Bylaws relating to Claims for Indemnification Events; (ii) in specific cases if the Board of Directors has approved the initiation or bringing of
such Claim; or (iii) as otherwise required under Section 145 of the DGCL, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification right, Expense Advances or insurance recovery, as the case may be.

  
 -12-

 (c) Claims Under Section 16(b) or Sarbanes-Oxley Act. The Company shall
not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee for expenses and the payment of profits arising from (i) the purchase and sale by Indemnitee of securities in violation of Section 16(b) of the Exchange Act, or
any similar successor statute; or (ii) any 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 (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); provided, however, that notwithstanding any limitation set forth in this
Section 10(c) regarding the Company’s obligation to provide indemnification, Indemnitee shall be entitled under Section 3 to receive Expense Advances with respect to any such Claim unless and until a court having
jurisdiction over the Claim shall have made a final judicial determination (as to which all rights of appeal therefrom have been exhausted or lapsed) that Indemnitee has violated such statute. 

11. Counterparts. This Agreement may be executed in counterparts and by facsimile or electronic transmission, each of which
shall constitute an original and all of which, together, shall constitute one instrument. 
 12. Binding Effect;
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors, and assigns, including any direct or indirect successor by purchase, merger,
consolidation or otherwise to all or substantially all of the business and/or assets of the Company, spouses, heirs, and personal and legal representatives. The Company shall require and cause any successor (whether direct or indirect by purchase,
merger, consolidation or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. This Agreement shall continue in effect regardless of whether Indemnitee continues to serve as a director,
officer, employee, agent or fiduciary (as applicable) of the Company or of any other enterprise at the Company’s request. The Company and Indemnitee agree that the Third-Party Indemnitors are express third party beneficiaries of this Agreement.

 13. Remedies of Indemnitee. 
 (a) Subject to Section 2(b)(iii), in the event that (i) a determination is made pursuant to this Agreement that Indemnitee is not entitled to indemnification under this Agreement; (ii) Expense
Advances are not timely made pursuant to Section 3 of this Agreement; (iii) no determination of entitlement to indemnification shall have been made pursuant to the 

  
 -13-

 
provisions of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification; (iv) payment of indemnification is not made pursuant to
Sections 2(a)(i), 2(e) or 7, of this Agreement within ten (10) days after receipt by the Company of a written request therefor; (v) payment of indemnification pursuant to the provisions of this Agreement is not made
within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification by a Reviewing Party; or (vi) the Company or any other person or entity takes or threatens to take any action to declare this Agreement void
or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee under this Agreement, Indemnitee shall be entitled to an
adjudication by a court regarding Indemnitee’s entitlement to such indemnification or Expense Advances. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to
the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first becomes aware or
reasonably should be aware that Indemnitee has the right to commence such proceeding pursuant to this Section 13(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b) In the event that a determination shall have been made pursuant to this Agreement that Indemnitee is not entitled to indemnification,
any judicial proceeding or arbitration commenced pursuant to this Section 13 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse
determination. In any judicial proceeding or arbitration commenced pursuant to this Section 13, the Company shall have the burden of proof and the burden of persuasion by clear and convincing evidence that Indemnitee is not entitled to
indemnification or Expense Advances, as the case may be. 
 (c) If a determination shall have been made pursuant to this
Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification; or (ii) a determination by a court that such indemnification is prohibited
under applicable law . 
 (d) The Company shall, to the fullest extent not prohibited by applicable law, be precluded from
asserting in any judicial proceeding or arbitration commenced pursuant to this Section 13 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any
such arbitrator that the Company is bound by all the provisions of this Agreement. 
 (e) It is the intent of the Company that,
to the fullest extent permitted by applicable law, Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or
otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee under this Agreement. In the event that any action is instituted by Indemnitee under this Agreement or under any
liability insurance policies 

  
 -14-

 
maintained by the Company to enforce or interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be indemnified for all Expenses incurred by Indemnitee with respect to such
action (including without limitation attorneys’ fees), regardless of whether Indemnitee is ultimately successful in such action, unless as a part of such action a court having jurisdiction over such action makes a final judicial determination
(as to which all rights of appeal therefrom have been exhausted or lapsed) that each of the material assertions made by Indemnitee as a basis for such action was not made in good faith or was frivolous; provided, however, that until
such final judicial determination is made, Indemnitee shall be entitled under Section 3 to receive payment of Expense Advances under this Agreement with respect to such action. In the event of an action instituted by or in the name of
the Company under this Agreement to enforce or interpret any of the terms of this Agreement, Indemnitee shall be entitled to be indemnified for all Expenses incurred by Indemnitee in defense of such action (including without limitation costs and
expenses incurred with respect to Indemnitee’s counterclaims and cross-claims made in such action), unless as a part of such action a court having jurisdiction over such action makes a final judicial determination (as to which all rights of
appeal therefrom have been exhausted or lapsed) that each of the material defenses asserted by Indemnitee in such action was made in bad faith or was frivolous; provided, however, that until such final judicial determination is made,
Indemnitee shall be entitled under Section 3 to receive payment of Expense Advances with respect to such action. 

14. Notices. All notices and other communications required or permitted under this Agreement shall be in writing, shall be
effective when given, and shall in any event be deemed to be given (a) three calendar days after deposit with the U.S. Postal Service or other applicable postal service, if delivered by first class mail, postage prepaid; (b) upon delivery,
if delivered by hand; (c) one business day after the business day of deposit with an overnight courier, freight prepaid; or (d) one day after the business day of delivery by facsimile transmission, if deliverable by facsimile transmission,
with a copy by first class mail, postage prepaid, and shall be addressed if to Indemnitee, at Indemnitee’s address as set forth beneath Indemnitee’s signature to this Agreement and if to the Company, at the address of its principal
corporate offices (attention: Chief Financial Officer) or at such other address as such party may designate by ten calendar days’ advance written notice to the other party hereto. 

15. Consent to Jurisdiction. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction of the courts
of the State of Delaware for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be commenced, prosecuted and continued only in the
Court of Chancery of the State of Delaware in and for New Castle County, which shall be the exclusive and only proper forum for adjudicating such a claim. 
 16. Severability. The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including any provision within a single section, paragraph or sentence)
are 

  
 -15-

 
held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable, and the remaining provisions shall remain enforceable to the fullest extent permitted by applicable law.
Furthermore, to the fullest extent possible, the provisions of this Agreement (including without limitation each portion of this Agreement containing any provision held to be invalid, void or otherwise unenforceable, that is not itself invalid, void
or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable. 
 17. Choice of Law. This Agreement, and all rights, remedies, liabilities, powers and duties of the parties to this Agreement, shall be governed by and construed in accordance with the laws
of the State of Delaware without regard to principles of conflicts of laws. 
 18. Primacy of Indemnification;
Subrogation. 
 (a) The Company hereby acknowledges that Indemnitee has or may in the future have certain
indemnification or Expense advancement rights and/or insurance provided by one or more Third-Party 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 any Third-Party Indemnitors to advance Expenses or to provide indemnification or insurance for the same Expenses 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, to the extent legally permitted and as required or permitted by the Certificate of Incorporation or the Bylaws (or any agreement between the Company and Indemnitee), without
regard to any rights Indemnitee may have against the Third-Party Indemnitors; and (iii) that it irrevocably waives, relinquishes and releases the Third-Party Indemnitors from any and all claims against the Third-Party 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 Third-Party 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 Third-Party Indemnitors shall have a right to receive from the Company, 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. 
 (b) Except as provided in Section 18(a) above, in the event of
payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee from any insurance policy purchased by the Company, who shall execute all documents required and shall do all
acts that may be necessary to secure such rights and to enable the Company effectively to bring suit to enforce such rights. In no event, however, shall the Company or any other person have any right of recovery, through subrogation or otherwise,
against (i) Indemnitee; (ii) any Third-Party Indemnitor; or (iii) any insurance policy purchased or maintained by Indemnitee or any Third-Party Indemnitor. 

  
 -16-

 19. Amendment and Termination. No amendment, modification, termination or
cancellation of this Agreement shall be effective unless it is in writing signed by both the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other provisions hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver. 
 20. Integration and Entire
Agreement. This Agreement sets forth the entire understanding between the parties hereto and supersedes and merges all previous written and oral negotiations, commitments, understandings and agreements relating to the subject matter hereof
between the parties hereto; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation, the Bylaws, any directors and officers insurance maintained by the Company and applicable law, and shall
not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 
 21. No
Construction as Employment Agreement. Nothing contained in this Agreement shall be construed as giving Indemnitee any right to employment by the Company or any of its subsidiaries or affiliated entities. 

22. Additional Acts. If, for the validation of any of the provisions in this Agreement, any act, resolution, approval or
other procedure is required, the Company undertakes to cause such act, resolution, approval or other procedure to be effected or adopted in a manner that will enable the Company to fulfill its obligations under this Agreement.
