1.

Exercise of Warrants.

(a)

Upon presentation and surrender at the principal executive office of the Company of this Warrant during the Exercise Period, along with the Election to Purchase form attached hereto as Exhibit A duly executed, together with a check to the Company in the amount of the Exercise Price 

multiplied by the number of shares of Common Stock being purchased, the Company will cause its Transfer Agent to deliver to the holder hereof, certificates of Common Stock which in the aggregate represent the number of shares of Common Stock being purchased. This Warrant may be partially exercised and, in the case of such partial exercise, the Company, upon surrender hereof, will deliver to the Holder a new Warrant representing the number of shares which have not been exercised.

(b)

If at any time after the six month anniversary of the Initial Exercise Date set forth above, or any successor provision then in effect, there is no effective registration statement registering, or no current prospectus available for, the resale of the shares of Common Stock underlying this Warrant by the Holder, then this Warrant may also be exercised, in whole or in part, solely with respect to such unregistered shares of Common Stock, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of shares of Common Stock underlying this Warrant equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: 

		
	(A) =

	the VWAP (as defined below) on the trading day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” as set forth in the applicable Election to Purchase;

	(B) =

	the Exercise Price of this Warrant, as may be adjusted hereunder; and

	(X) =

	the number of shares of Common Stock underlying this Warrant that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market (as defined below) on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a trading day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by Pink OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holder and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“Trading Market” means any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE MKT, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, the OTC Bulletin Board, OTCQX or OTCQB (or any successors to any of the foregoing).

2.

Exercise Period.  

(a)

The right to acquire shares of Common Stock of the Company pursuant to this Warrant shall commence on the date hereof.

After the Expiration Date, the Holder shall have no right to purchase any shares of Common Stock pursuant to this Warrant.

(b)

The rights represented by this Warrant may be exercised by the Holder, in whole or in part (with respect to shares of Common Stock), subject to the conditions contained herein and at any time within the period specified in Section 2(a) by: (i) surrender of this Warrant for calculation (with the 

-2-

Election to Purchase form at the end hereof properly executed) at the principal executive office of the Company (or at such other office or agency of the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company); (ii) payment to the Company of the Exercise Price for the number of shares of Common Stock specified in the Election to Purchase form, together with the amount of applicable stock transfer taxes, if any; and/or (iii) delivery to the Company of a duly executed agreement signed by the person(s) designated in the Election to Purchase form to the effect that such person(s) agree(s) to be bound by all of the terms and conditions of this Warrant.  This Warrant shall be deemed to have been exercised, in whole or in part to the extent specified, immediately prior to the close of business on the date on which all of the applicable provisions of this Section 2(b) are reasonably satisfied, and the person(s) designated in the Election to Purchase form shall become the holder(s) of record of the shares of Common Stock issuable upon such exercise at that time and date.

3.

Rights and Obligations of Holders of this Warrant:  Anti-Dilution.

(a)

The Holder of this Warrant shall not, by virtue hereof, be entitled to any rights of a stockholder in the Company, either at law or in equity; provided, however, that in the event any certificate representing shares of Common Stock or other securities is issued to the Holder hereof upon exercise of some or all of this Warrant, such Holder shall, for all purposes, be deemed to have become the holder of record of such Common Stock on the date on which all of the applicable provisions of Section 2(b) have been met, irrespective of the date of delivery of such share certificate.

(b)

In case the Company shall (i) pay a dividend in its Common Stock or make a distribution in its Common Stock, (ii) subdivide its outstanding Common Stock into a greater number of shares, (iii) combine its outstanding Common Stock into a smaller number of shares (including a recapitalization in connection with any consolidation or merger), then the Exercise Price on the record date of such division or the effective date of such action shall be adjusted by multiplying such Exercise Price by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately before such event and the denominator of which is the number of shares of Common Stock outstanding immediately after such event and the number of shares of Common Stock for which this Warrant may be exercised immediately before such event shall be adjusted by multiplying such number by a fraction, the numerator of which is the Exercise Price immediately before such event and the denominator of which is the Exercise Price immediately after such event.

(c)

In the case of any consolidation or merger of the Company with or into another corporation (other than any consolidation or merger in which the Company is the continuing corporation and which does not result in any reclassification of the outstanding shares of Common Stock) or the conversion of such outstanding shares of Common Stock into shares or other stock or other securities or property, or the liquidation, sale or transfer of the property of the Company as an entity or substantially as an entirety and for other unusual events, there shall be deliverable upon exercise of the Warrant (in lieu of the number of shares of Common Stock theretofore deliverable) the number of shares of stock or other securities or property to which a holder of the number of shares of Common Stock which would otherwise have been deliverable upon the exercise of this Warrant would have been entitled upon such action if this Warrant had been exercised immediately prior to such action.

(d)

Either the Company or the Holder(s) may require that the Company assign the obligations of the Company described in this Warrant to any successor of the Company if the Company is not the surviving entity of a merger or consolidation.  The Company must give the Holder(s) hereof five (5) business days notice of the terms of any such consolidation or merger and the terms thereof.

4.

Covenants of the Company.

(a)

The Company covenants and agrees that all shares of Common Stock issuable upon exercise of this Warrant will, upon delivery, be duly and validly authorized and issued, fully-paid and non-assessable.

(b)

The Company covenants and agrees that it will at all times prior to expiration of this Warrant reserve and keep available an authorized number of shares of its Common Stock and other applicable securities sufficient to permit the exercise in full of all outstanding convertible securities, options, warrants and rights, including this Warrant.

5.

Issuance of Certificates.  As soon as possible after any full or partial exercise of this Warrant, but in any event no more than ten (10) business days, the Company, at its expense, will cause to be issued in the name of and delivered to the Holder of this Warrant, a certificate or certificates for the number of fully paid and non-assessable shares of Common Stock to which that Holder shall be entitled on such exercise.  No fractional shares will be issued on exercise of this Warrant.  If, on any exercise of this Warrant, a fractional share results, the Company will pay the cash value of that fractional share, calculated on the basis of the Exercise Price.  All such certificates shall bear a restrictive legend to the effect that the shares of Common Stock represented by such certificate have not been registered under the Securities Act, and the shares of Common Stock may not be sold or transferred in the absence of such registration or an exemption therefrom, such legend to be substantially in the form of the bold face language appearing on Page 1 of this Warrant.

6.

Successors and Assigns: Transfer.

(a)

This Warrant shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns.

Notwithstanding the foregoing, this Warrant may only be transferred to members, managers, officers, directors, employees, consultants or heirs of the initial Holder hereof.  This Warrant shall be deemed to have been transferred, in whole or in part to the extent specified, immediately prior to the close of business on the date the provisions of this Section 6 are satisfied, and the transferee(s) designated in the Transfer form shall become the holder(s) of record at that time and date. The Company shall issue, in the name(s) of the designated transferee(s) (including the Holder if this Warrant has been transferred in part) a new Warrant or Warrants of like tenor and representing, in the aggregate, rights to purchase the same number of shares of Common Stock as are then purchasable under this Warrant.

proposed registration to all other Stockholders. Such Stockholders shall have the right, by giving written notice to the Company within 30 days after the Company provides its notice, to elect to have included in such registration such of their
Registrable Shares as such Stockholders may request in such notice of election, subject in the case of an underwritten offering to the terms of Section 2.1(d). Thereupon, the Company shall, as expeditiously as possible, use its best efforts to
effect the registration on an appropriate registration form of all Registrable Shares which the Company has been requested to so register; provided, however, that in the case of a registration requested under Section 2.1(b), the Company will
only be obligated to effect such registration on Form S-3 (or any successor form). 
 (d) If
the Initiating Holders intend to distribute the Registrable Shares covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.1(a) or (b), as the case may be, and
the Company shall include such information in its written notice referred to in Section 2.1(c). In such event, (i) the right of any other Stockholder to include its Registrable Shares in such registration pursuant to Section 2.1(a) or
(b), as the case may be, shall be conditioned upon such other Stockholder’s participation in such underwriting on the terms set forth herein, and (ii) all Stockholders including Registrable Shares in such registration shall enter into an
underwriting agreement upon customary terms with the underwriter or underwriters 

  
 -5- 

 
managing the offering; provided that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of the Stockholders materially greater than the
obligations of the Stockholders pursuant to Section 2.5. The Initiating Holders shall have the right to select the managing underwriter(s) for any underwritten offering requested pursuant to Section 2.1(a) or (b), subject to the approval
of the Company, which approval will not be unreasonably withheld, conditioned or delayed. If any Stockholder who has requested inclusion of its Registrable Shares in such registration as provided above disapproves of the terms of the underwriting,
such Stockholder may elect, by written notice to the Company, to withdraw its Registrable Shares from such Registration Statement and underwriting. If the managing underwriter advises the Company in writing that marketing factors require a
limitation on the number of shares to be underwritten, the number of Registrable Shares to be included in the Registration Statement and underwriting shall be allocated first among all Purchasers, second among all Existing Preferred Stockholders and
thereafter among the other Stockholders requesting registration in proportion, as nearly as practicable, to the respective number of Registrable Shares held by them on the date of the request for registration made by the Initiating Holders pursuant
to Section 2.1(a) or (b), as the case may be. If any Stockholder would thus be entitled to include more Registrable Shares than such Stockholder requested to be registered, the excess shall be allocated first among the other requesting
Purchasers, second among the other requesting Existing Preferred Stockholders, and then among the other requesting Stockholders pro rata in the manner described in the preceding sentence. 

(e) The Company shall not be required to effect more than two registrations pursuant to Section 2.1(a). In addition, the Company shall
not be required to effect any registration within six months after the effective date of the Registration Statement relating to the Initial Public Offering. For purposes of this Section 2.1(e), a Registration Statement shall not be counted
until such time as such Registration Statement has been declared effective by the Commission (unless the Initiating Holders withdraw their request for such registration (other than as a result of information concerning the business or financial
condition of the Company which is made known to the Stockholders after the date on which such registration was requested) and elect not to pay the Registration Expenses therefor pursuant to Section 2.4). For purposes of this
Section 2.1(e), a Registration Statement shall not be counted if, as a result of an exercise of the underwriter’s cut-back provisions, less than 50% of the total number of Registrable Shares that
Stockholders have requested to be included in such Registration Statement are so included. 
 (f) Notwithstanding the
foregoing, if the Company shall furnish to Holders requesting a Registration Statement pursuant to this Section 2.1 a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of
Directors of the Company (the “Board”) it would be materially detrimental to the Company and its stockholders for such registration statement to become effective or to remain effective as long as such registration statement
would otherwise be required to remain effective because such action (x) would materially interfere with a significant acquisition, corporate reorganization or other similar transaction involving the Company, (y) would require premature
disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (z) would render the Company unable to comply with requirements under the Securities Act or Exchange Act, the Company shall
have the right to defer taking action with respect to such filing for a period of not more than forty-five (45) days after receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right more than once in any twelve-month period; and provided further that the Company shall not register any securities for its own account or that of any other stockholder during
such forty-five (45) day period. 
 2.2 Incidental Registration. 

(a) Whenever the Company proposes to file a Registration Statement (other than a Registration Statement filed pursuant to Section 2.1) at
any time and from time to time, it will, 

  
 -6- 

 
prior to such filing, give written notice to all Stockholders of its intention to do so. Upon the written request of a Stockholder or Stockholders given within 20 days after the Company provides
such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall, subject to the provisions of Section 2.2(b), use its best efforts to cause all Registrable Shares which the Company has
been requested by such Stockholder or Stockholders to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the
request of such Stockholder or Stockholders; provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 2.2, whether or not any Holder has elected to include Registrable Shares in
such registration, without obligation to any Stockholder. 
 (b) If the registration for which the Company gives notice pursuant to
Section 2.2(a) is a registered public offering involving an underwriting, the Company shall so advise the Stockholders as a part of the written notice given pursuant to Section 2.2(a). In such event, (i) the right of any Stockholder
to include its Registrable Shares in such registration pursuant to this Section 2.2 shall be conditioned upon such Stockholder’s participation in such underwriting on the terms set forth herein and (ii) all Stockholders including
Registrable Shares in such registration shall enter into an underwriting agreement upon customary terms with the underwriter or underwriters selected for the underwriting by the Company; provided that such underwriting agreement shall not provide
for indemnification or contribution obligations on the part of Stockholders materially greater than the obligations of the Stockholders pursuant to Section 2.5. If any Stockholder who has requested inclusion of its Registrable Shares in such
registration as provided above disapproves of the terms of the underwriting, such person may elect, by written notice to the Company, to withdraw its shares from such Registration Statement and underwriting. If the managing underwriter advises the
Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the shares held by holders of securities of the Company other than Stockholders and Other Holders shall be excluded from such Registration
Statement and underwriting to the extent deemed advisable by the managing underwriter, and, if a further reduction of the number of shares is required, the number of shares that may be included in such Registration Statement and underwriting shall
be allocated first to the shares being sold for account of the Company, second among all Purchasers, third among all Existing Preferred Stockholders and thereafter among the other Stockholders requesting registration in proportion, as nearly as
practicable, to the respective number of shares of Common Stock (on an as-converted basis) held by them on the date the Company gives the notice specified in Section 2.2(a); provided that, unless such
registration is in connection with the Company’s Initial Public Offering, the number of Registrable Shares permitted to be included therein shall in any event be at least 25% of the securities included therein (based on aggregate market
values). If any Stockholder would thus be entitled to include more shares than such holder requested to be registered, the excess shall be allocated first among other requesting Purchasers, second among the other requesting Existing Preferred
Stockholders and then among the other Stockholders pro rata in the manner described in the preceding sentence. 
 2.3 Registration
Procedures. 
 (a) If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the
registration of any Registrable Shares under the Securities Act, the Company shall: 
 (i) file with the Commission a Registration
Statement with respect to such Registrable Shares and use its best efforts to cause that Registration Statement to become effective as soon as possible; 

  
 -7- 

 (ii) as expeditiously as reasonably possible prepare and file with the Commission any amendments
and supplements to the Registration Statement and the prospectus included in the Registration Statement as may be necessary to comply with the provisions of the Securities Act (including the anti-fraud
provisions thereof) and to keep the Registration Statement effective for one hundred eighty (180) days from the effective date or such lesser period until all such Registrable Shares are sold; provided, however, that (i) such 180-day period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of Common Stock (or other
securities) of the Company; and (ii) in the case of any registration of Registrable Shares on Form S-3 which are intended to be offered on a continuous or delayed basis, subject to compliance with
applicable SEC rules, such 180-day period shall be extended for up to two hundred forty (240) days, if necessary, to keep the registration statement effective until all such Registrable Shares are sold;

 (iii) as expeditiously as reasonably possible furnish to each Selling Stockholder such reasonable numbers of copies of the Prospectus,
including any preliminary Prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the
Registrable Shares owned by such Selling Stockholder; 
 (iv) as expeditiously as reasonably possible use its best efforts to register or
qualify the Registrable Shares covered by the Registration Statement under the securities or Blue Sky laws of such states as the Selling Stockholders shall reasonably request; provided, however, that the Company shall not be required in connection
with this paragraph (iv) to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction, unless the Company is already subject to service in such jurisdiction and except as may be required by the
Securities Act; 
 (v) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the underwriter(s) of such offering; 
 (vi) as expeditiously as reasonably possible cause all
such Registrable Shares to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed; 

(vii) provide a transfer agent and registrar for all such Registrable Shares not later than the effective date of such Registration
Statement; 
 (viii) promptly make available for inspection by the Selling Stockholders, any managing underwriter participating in any
disposition pursuant to such Registration Statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the Selling Stockholders, all financial and other records, pertinent corporate documents and
properties of the Company and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such
Registration Statement; 
 (ix) notify each Selling Stockholder, promptly after it shall receive notice thereof, of the time when such
Registration Statement has become effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed; and 

  
 -8- 

 (x) as expeditiously as reasonably possible following the effectiveness of such Registration
Statement, notify each seller of such Registrable Shares of any request by the Commission for the amending or supplementing of such Registration Statement or Prospectus. 

(b) If the Company has delivered a Prospectus to the Selling Stockholders and after having done so the Prospectus is amended to comply with
the requirements of the Securities Act, the Company shall promptly notify the Selling Stockholders of the same and, if requested by the Company, the Selling Stockholders shall immediately cease making offers of Registrable Shares and return all
Prospectuses to the Company. The Company shall promptly provide the Selling Stockholders with revised Prospectuses and, following receipt of the revised Prospectuses, the Selling Stockholders shall be free to resume making offers of the Registrable
Shares. 
 (c) In the event that, in the judgment of the Company, it is advisable to suspend use of a Prospectus included in a Registration
Statement due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify all Selling Stockholders to
such effect, and, upon receipt of such notice, each such Selling Stockholder shall immediately discontinue any sales of Registrable Shares pursuant to such Registration Statement until such Selling Stockholder has received copies of a supplemented
or amended Prospectus or until such Selling Stockholder is advised in writing by the Company that the then current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated
by reference in such Prospectus. Notwithstanding anything to the contrary herein, the Company shall not exercise its rights under this Section 2.3(c) to suspend sales of Registrable Shares for a period in excess of 30 days consecutively or 60
days in any 365-day period. 
 2.4 Allocation of Expenses. The Company will pay all
Registration Expenses for all registrations under this Agreement; provided, however, that if a registration under Section 2.1 is withdrawn at the request of the Initiating Holders (other than as a result of information concerning a material
adverse change in the business or financial condition of the Company which is made known to the Selling Stockholders after the date on which such registration was requested) and if the Initiating Holders elect not to have such registration counted
as a registration requested under Section 2.1, the Selling Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration. 

2.5 Indemnification and Contribution. 

(a) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company will
indemnify and hold harmless each Selling Stockholder, each underwriter of such Registrable Shares, and each other person, if any, who controls such Selling Stockholder or underwriter within the meaning of the Securities Act or the Exchange Act
against any losses, claims, damages or liabilities, joint or several, to which such Selling Stockholder, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which
such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, (ii) the omission or
alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the Registration Statement 

  
 -9- 

 
or the offering contemplated thereby; and the Company will reimburse such Selling Stockholder, underwriter and each such controlling person for any legal or any other expenses reasonably incurred
by such Selling Stockholder, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in writing, by or on behalf of such Selling Stockholder, underwriter or controlling person specifically for use in the preparation thereof. 

(b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each Selling
Stockholder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of
the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors and officers, underwriter or controlling person may become subject under the Securities Act, Exchange
Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the
Registration Statement, or (ii) any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if and to the extent (and only to the extent) that the statement
or omission was made in reliance upon and in conformity with information relating to such Selling Stockholder furnished in writing to the Company by such Selling Stockholder specifically for use in connection with the preparation of such
Registration Statement, prospectus, amendment or supplement; provided, however, that the obligations of a Selling Stockholder hereunder shall be limited to an amount equal to the net proceeds to such Selling Stockholder of Registrable Shares sold in
connection with such registration. 
 (c) Each Indemnified Party shall give notice to the Indemnifying Party promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld, conditioned or delayed); and, provided, further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.5 except to the extent that the Indemnifying Party is adversely affected by such failure. The Indemnified Party
may participate in such defense at such party’s expense; provided, however, that the Indemnifying Party shall pay such expense if the Indemnified Party reasonably concludes that representation of such Indemnified Party by the counsel retained
by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding; provided further that in no event shall the
Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party does not
elect to assume such defense. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim
or litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. 

  
 -10- 

 (d) In order to provide for just and equitable contribution in circumstances in which the
indemnification provided for in this Section 2.5 is due in accordance with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses, claims, damages and liabilities referred to herein, then the
Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities to which such party may be subject in such
proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Selling Stockholders on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative fault of the Company and the Selling Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to
information supplied by the Company or the Selling Stockholders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Stockholders agree
that it would not be just and equitable if contribution pursuant to this Section 2.5(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this Section 2.5(d), (i) in no case shall any one Selling Stockholder be liable or responsible for any amount in excess of the net proceeds received by such Selling Stockholder from the offering of
Registrable Shares and (ii) the Company shall be liable and responsible for any amount in excess of such proceeds; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding
against such party in respect of which a claim for contribution may be made against another party or parties under this Section 2.5(d), notify such party or parties from whom contribution may be sought, but the omission so to notify such party
or parties from whom contribution may be sought shall not relieve such party from any other obligation it or they may have thereunder or otherwise under this Section 2.5(d). No party shall be liable for contribution with respect to any action,
suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. 

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 

(f) The rights and obligations of the Company and the Selling Stockholders under this Section 2.5 shall survive the termination of this
Agreement. 
 2.6 Other Matters with Respect to Underwritten Offerings. In the event that Registrable Shares are sold pursuant to a
Registration Statement in an underwritten offering pursuant to Section 2.1, the Company agrees to (a) enter into an underwriting agreement containing customary representations and warranties with respect to the business and operations of
the Company and customary covenants and agreements to be performed by the Company, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering; (b) use its best efforts
to cause its legal counsel to render customary opinions to the underwriters and the Selling Stockholders with respect to the Registration Statement; and (c) use its best efforts to cause its independent public accounting firm to issue customary
“cold comfort letters” to the underwriters and the Selling Stockholders with respect to the Registration Statement. 

  
 -11- 

 2.7 Information by Stockholder. It shall be a condition precedent to the obligations of
the Company to take any action pursuant to this Section 2 with respect to the Registrable Shares of any Selling Stockholder that such holder of Registrable Shares included in a registration shall furnish to the Company such information
regarding such holder and the distribution proposed by such holder as the Company may reasonably request in writing and as shall be reasonably required to effect the registration of such Holder’s Registrable Shares. 

2.8 “Lock-Up” Agreement; Confidentiality of Notices. Each Stockholder agrees, if
requested by the Company and the managing underwriter of the Initial Public Offering, (i) not to (a) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any Registrable Shares or other securities of the Company (excluding securities acquired in the Initial Public Offering or
in the public market after such offering) or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any Registrable Shares or other securities of the Company (excluding
securities acquired in the Initial Public Offering or in the public market after such offering), whether any transaction described in clause (a) or (b) is to be settled by delivery of securities, in cash or otherwise, during the period
beginning on the date of the filing of such registration statement with the Commission and ending 180 days after the date of the final prospectus relating to the Initial Public Offering (plus up to an additional 34 days to the extent requested by
the managing underwriters for such offering in order to address Rule 2711(f) of FINRA or any similar successor provision) and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing
underwriters at the time of such offering; provided, that all stockholders of the Company then holding at least 1% of the outstanding Common Stock (on an as-converted basis) and all officers and
directors of the Company enter into similar agreements. 
 The Company may impose stop-transfer
instructions with respect to the Registrable Shares or other securities subject to the foregoing restriction until the end of such period. 

As a condition to the obligation of the Stockholders under this Section 2.8, the Company agrees to use its reasonable best efforts to
ensure that the “lock-up” obligation of the Stockholders under this Section 2.8, and any agreement entered into by the Stockholders as a result of their obligations under this Section 2.8,
shall (i) allow for periodic early releases of portions of the securities subject to such “lock-up” obligations, which may be conditioned upon the trading price of the Company’s Common
Stock and (ii) provide that all Stockholders will participate on a pro rata basis in any early release of any stockholder. 
 Any
Stockholder receiving any written notice from the Company regarding the Company’s plans to file a Registration Statement shall treat such notice confidentially and shall not disclose such information to any person other than as necessary to
exercise its rights under this Agreement. 
 2.9 Limitation on Subsequent Registration Rights. The Company shall not, without the
prior written consent of the Purchasers holding a majority of the Registrable Shares then held by the Purchasers, enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or
prospective holder (a) to include such securities in any registration unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such
securities will not reduce the number of Registrable Shares of the Stockholders that are included or (b) to demand registration of any securities held by such holder or prospective holder. 

  
 -12- 

 2.10 Rule 144 Requirements. After the earliest of (i) the closing of the sale of
securities of the Company pursuant to a Registration Statement, (ii) the registration by the Company of a class of securities under Section 12 of the Exchange Act, or (iii) the issuance by the Company of an offering circular pursuant
to Regulation A under the Securities Act, the Company agrees to: 
 (a) make and keep current public information about the Company
available, as those terms are understood and defined in Rule 144; 
 (b) use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and 

(c) furnish to any holder of Registrable Shares upon request (i) a written statement by the Company as to its compliance with the
reporting requirements of Rule 144 and of the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company,
and (iii) such other reports and documents of the Company as such holder may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration. 

2.11 Termination. All of the Company’s obligations to register Registrable Shares under Sections 2.1 and 2.2 shall terminate
upon the earliest of (a) five years after the closing of the Initial Public Offering, (b) the date on which no Stockholder holds any Registrable Shares or (c) a Company Sale. 

 

	 	3.	Right of First Refusal. 

 3.1 Rights of Purchasers to Acquire Offered Securities.

 (a) The Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or
exchange, any Offered Securities, unless in each such case the Company shall have first complied with this Section 3.1. The Company shall deliver to each Purchaser an Offer, which shall (i) identify and describe the Offered Securities,
(ii) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (iii) identify the persons or entities (if known) to which or
with which the Offered Securities are to be offered, issued, sold or exchanged, and (iv) offer to issue and sell to or exchange with such Purchaser that is a Qualified Purchaser (A) such Qualified Purchaser’s Basic Amount and
(B) such Qualified Purchaser’s Undersubscription Amount. 
 (b) To accept an Offer, in whole or in part, a Qualified Purchaser
must deliver to the Company, on or prior to the date 20 days after the date of delivery of the Offer, a Notice of Acceptance providing a representation letter certifying that such Qualified Purchaser is an accredited investor within the meaning of
Rule 501 under the Securities Act and indicating the portion of the Qualified Purchaser’s Basic Amount that such Qualified Purchaser elects to purchase and, if such Qualified Purchaser shall elect to purchase all of its Basic Amount, the
Undersubscription Amount (if any) that such Qualified Purchaser elects to purchase. If the Basic Amounts subscribed for by all Qualified Purchasers are less than the total of all of the Basic Amounts available for purchase, then each Qualified
Purchaser who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the
Undersubscription Amounts subscribed for exceed the Available Undersubscription Amount, each Qualified Purchaser who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available

  
 -13- 

 
Undersubscription Amount as the Undersubscription Amount subscribed for by such Qualified Purchaser bears to the total Undersubscription Amounts subscribed for by all Qualified Purchasers,
subject to rounding by the Board to the extent it deems reasonably necessary. 
 (c) The Company shall have 90 days from the expiration of
the period set forth in Section 3.1(b) to issue, sell or exchange all or any part of the Refused Securities, but only to the offerees or purchasers described in the Offer (if so described therein) and only upon terms and conditions (including,
without limitation, unit prices and interest rates) which are not more favorable, in the aggregate, to the acquiring person or persons or less favorable to the Company than those set forth in the Offer. 

(d) In the event the Company shall propose to sell less than all the Refused Securities, then each Qualified Purchaser may, at its sole
option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the Qualified Purchaser
elected to purchase pursuant to Section 3.1(b) multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities
to be issued or sold to Qualified Purchasers pursuant to Section 3.1(b) prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Qualified Purchaser so elects
to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been
offered to the Qualified Purchasers in accordance with Section 3.1(a). 
 (e) Upon (i) the closing of the issuance, sale or
exchange of all or less than all of the Refused Securities or (ii) such other date agreed to by the Company and Qualified Purchasers who have subscribed for a majority of the Offered Securities subscribed for by the Qualified Purchasers, such
Qualified Purchaser or Purchasers shall acquire from the Company and the Company shall issue to such Qualified Purchaser or Purchasers, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to
Section 3.1(d) if any of the Qualified Purchasers has so elected, upon the terms and conditions specified in the Offer. 
 (f) The
purchase by the Qualified Purchasers of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Qualified Purchasers of a purchase agreement relating to such Offered Securities reasonably
satisfactory in form and substance to the Qualified Purchasers and their respective counsel. 
 (g) Any Offered Securities not acquired by
the Qualified Purchasers or other persons in accordance with Section 3.1(c) may not be issued, sold or exchanged until they are again offered to the Qualified Purchasers under the procedures specified in this Agreement. 

(h) The rights of the Qualified Purchasers under this Section 3.1 shall not apply to:

3.2 Rights of Purchasers to Acquire Debt Securities. 

(a) The Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange,
any debt securities, including without limitation, debt securities convertible into capital stock of the Company and debt securities accompanied by the issuance of options, warrants or other securities convertible into capital stock of the Company,
or 

  
 -15- 

 
otherwise incur or become liable for any indebtedness (collectively, “Debt”), unless in each such case the Company shall have first complied with this
Section 3.2. The Company shall deliver to each Purchaser written notice of any proposed or intended issuance, sale, exchange or incurrence of Debt (the “Debt Offer”), which notice shall (i) identify
and describe the Debt, (ii) describe the price and other terms upon which it will be issued, and the number or amount of Debt to be issued, sold, exchanged or incurred, (iii) identify the persons or entities (if known) to which or with
which the Debt is to be offered, issued, sold, exchanged or borrowed and (iv) offer to issue and sell to, exchange with or borrow from such Purchaser that is a Qualified Purchaser (A) such Qualified Purchaser’s pro rata portion of the
Debt determined by multiplying the number or amount, as the case may be, of Debt by a fraction, the numerator of which is the aggregate number of shares of Series E Preferred Stock then held by such Qualified Purchaser and the denominator of
which is the total number of shares of Series E Preferred Stock then held by all Qualified Purchasers (the “Basic Debt Amount”) and (B) such Qualified Purchaser’s additional portion of Debt
attributable to the Basic Debt Amounts of other Qualified Purchasers as such Qualified Purchaser indicates it will purchase or acquire should the other Qualified Purchasers subscribe for less than their Basic Debt Amounts (the
“Undersubscription Debt Amount”). 
 (b) To accept a Debt Offer (which must be accepted
in whole and not in part), a Qualified Purchaser must deliver to the Company, on or prior to the date 20 days after the date of delivery of the Debt Offer, a written notice from such Qualified Purchaser (“Notice of Debt
Acceptance”) providing a representation letter certifying that such Qualified Purchaser is an accredited investor within the meaning of Rule 501 under the Securities Act and indicating the portion of the Qualified
Purchaser’s Basic Debt Amount that such Qualified Purchaser elects to purchase or lend and, if such Qualified Purchaser shall elect to purchase all of its Basic Debt Amount, the Undersubscription Debt Amount (if any) that such Qualified
Purchaser elects to purchase or lend. If the Basic Debt Amounts subscribed for by all Qualified Purchasers are less than the total of all of the Basic Debt Amounts available for purchase, then each Qualified Purchaser who has set forth an
Undersubscription Debt Amount in its Notice of Debt Acceptance shall be entitled to purchase, in addition to the Basic Debt Amounts subscribed for, the Undersubscription Debt Amount it has subscribed for; provided, however, that if the
Undersubscription Debt Amounts subscribed for exceed the difference between the total of all of the Basic Debt Amounts available for purchase by Qualified Purchasers pursuant to this Section 3.2 and the Basic Debt Amounts subscribed for
pursuant to this Section 3.2 (the “Available Undersubscription Debt Amount”), each Qualified Purchaser who has subscribed for any Undersubscription Debt Amount shall be entitled to purchase only that
portion of the Available Undersubscription Debt Amount as the Undersubscription Debt Amount subscribed for by such Qualified Purchaser bears to the total Undersubscription Debt Amounts subscribed for by all Qualified Purchasers, subject to rounding
by the Board to the extent it deems reasonably necessary. 
 (c) The Company shall have 90 days from the expiration of the
period set forth in Section 3.2(b) to issue, sell, exchange or borrow all or any portion of the Debt as to which a Notice of Debt Acceptance has not been given by the Qualified Purchasers pursuant to Section 3.2(b) (the
“Refused Debt”), but only to the offerees or purchasers described in the Debt Offer (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates)
which are not more favorable, in the aggregate, to the acquiring person or persons or less favorable to the Company than those set forth in the Debt Offer. 

(d) In the event the Company shall propose to sell less than all the Refused Debt, then each Qualified Purchaser may, at its sole option and
in its sole discretion, reduce the number or amount of Debt specified in its Notice of Debt Acceptance to an amount that shall be not less than the number or amount of Debt that the Qualified Purchaser elected to purchase or lend pursuant to
Section 3.2(b) multiplied by a fraction, (i) the numerator of which shall be the number or amount of Debt the Company actually proposes to issue, sell, exchange or borrow (including Debt to be issued or sold to

  
 -16- 

 
Qualified Purchasers pursuant to Section 3.2(b) prior to such reduction) and (ii) the denominator of which shall be the original amount of Debt. In the event that any Qualified
Purchaser so elects to reduce the number or amount of Debt specified in its Notice of Debt Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of Debt unless and until such securities or indebtedness have
again been offered to the Qualified Purchasers in accordance with Section 3.2(a). 
 (e) Upon (i) the closing of the issuance,
sale, exchange or borrowing of all or less than all of the Refused Debt or (ii) such other date agreed to by the Company and Qualified Purchasers who have subscribed for a majority of the Debt subscribed for by the Qualified Purchasers, such
Qualified Purchaser or Purchasers shall acquire from the Company and the Company shall issue to such Qualified Purchaser or Purchasers, the number or amount of Debt specified in the Notices of Debt Acceptance, as reduced pursuant to
Section 3.2(d) if any of the Qualified Purchasers has so elected, upon the terms and conditions specified in the Debt Offer. 
 (f)
The purchase by the Qualified Purchasers of any Debt is subject in all cases to the preparation, execution and delivery by the Company and the Qualified Purchasers of a purchase or loan agreement relating to such Debt reasonably satisfactory in form
and substance to the Qualified Purchasers and their respective counsel. 
 (g) Any Debt not acquired by the Qualified Purchasers or other
persons in accordance with Section 3.2(c) may not be issued, sold or exchanged until they are again offered to the Qualified Purchasers under the procedures specified in this Agreement. 

(h) Each Assigning Investor may assign to one or more of its Assignee Investors its right to purchase from or lend to the Company all or a
portion of the Debt that the Assigning Investor is entitled to purchase from or lend to the Company, provided the Assigning Investor notifies the Company of such assignment prior to the closing of the issuance, sale, exchange or borrowing of the
Debt. An Assignee Investor shall then have such assigned right to purchase Debt or otherwise lend funds to the Company as if it were a recipient of the applicable Debt offer. Notwithstanding any provision of this Agreement to the contrary, the
Company and each of the other Purchasers acknowledge and agree that any Debt that is issued by the Company and is held by an Assignee Investor shall be automatically reassigned to the respective Assigning Investor as of the earlier of: (i) the
time that such Assigning Investor notifies the Company that such reassignment is to be effective; or (ii) the time immediately prior to the conversion of such Debt into capital stock of the Company or securities convertible into capital stock
of the Company. 
 (i) The Company and each Purchaser severally agrees and covenants that at any time and from time to time it will
promptly execute and deliver to each other or any other parties such further instruments and documents and take such further action as the Company or a Purchaser may reasonably require in order to carry out the full intent and purpose of this
Section 3.2. 
 3.3 Additional Rights of the Purchasers. 

(a) In connection with any Offer, in the event that the Company desires to offer, issue or sell Offered Securities to, or exchange
Offered Securities with, a Purchaser in an amount that exceeds the sum of such Qualified Purchaser’s Basic Amount and the Undersubscription Amount that such Qualified Purchaser is entitled to purchase (an “Excess Qualified
Purchaser”), the Company shall deliver to each Purchaser that has indicated its election to purchase Offered Securities a notice (the “Excess Amount Notice”), which shall (i) identify
each Excess Qualified Purchaser, (ii) disclose the amount by which the total number of Offered Securities that the Company desires to offer, issue, sell or exchange to Excess Qualified Purchasers exceeds the total of the Basic Amounts and
Undersubscription 

  
 -17- 

 
Amounts that all such Excess Qualified Purchasers are entitled to purchase pursuant to Section 3.1 (such excess amount, the “Excess Amount”) and
(iii) offer to issue and sell to each Purchaser that has indicated its election to purchase Offered Securities (including without limitation, each Excess Qualified Purchaser) its pro rata portion of the Excess Amount determined by multiplying
the Excess Amount by a fraction, the numerator of which is the sum of the Basic Amount and Undersubscription Amount that such holder is entitled to purchase and the denominator of which is the Excess Amount. 

(b) To accept an offer contained in an Excess Amount Notice pursuant to this Section 3.3, in whole or in part, a Qualified Purchaser
must deliver to the Company, on or prior to the date 10 days after the date of delivery of the Excess Amount Notice, a notice of acceptance indicating the portion of the Excess Amount that such Excess Qualified Purchaser elects to purchase,
provided, however, that if any Excess Qualified Purchaser does not elect to purchase all of its pro rata portion of the Excess Amount, such available portion of the Excess Amount shall be allocated to each Excess Qualified Purchaser who has elected
to purchase all of its pro rata portion of the Excess Amount that it is entitled to purchase, pro rata based on the sum of such Excess Qualified Purchaser’s Basic Amount, the Undersubscription Amount that such Excess Qualified Purchaser is
entitled to purchase and the portion of the Excess Amount that such Excess Qualified Purchaser is entitled to purchase (prior to any such allocation), subject to rounding by the Board to the extent it deems reasonably necessary. 

(c) The Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange,
any Offered Securities, unless in each case the Company shall have first complied with Section 3.1 and this Section 3.3. 
 3.4
Termination. This Section 3 shall terminate upon the earlier of the closing of a Company Sale or the closing of an Initial Public Offering. 
  

	 	4.	Covenants.

“Purchaser”, “Existing Preferred Stockholder” and/or “Common Stockholder”, as the case may be depending on the nature of the transferor, for purposes of this Agreement; provided that such assignment of rights shall be
contingent upon the transferee providing a written instrument to the Company notifying the Company of such transfer and assignment and agreeing in writing to be bound by the terms of this Agreement. Notwithstanding the foregoing, any person or
entity to which any Shares or Registrable Shares are 

  
 -22- 

 
transferred by a Stockholder, whether voluntarily or by operation of law, shall be bound by the obligations under Section 2.8 to the same extent as if such transferee were a Stockholder

affiliated entities or persons).

or Common Stockholder, as the case may be, unless such amendment, termination or waiver applies to all Purchasers, Qualified Purchasers, Stockholders, Existing Preferred Stockholders or Common Stockholders, as the case may be, in the same fashion
(it being agreed that a waiver of the provisions of Section 3 with respect to a particular transaction shall be deemed to apply to all Qualified Purchasers in the same fashion if such waiver does so by its terms, notwithstanding the fact that
certain Qualified Purchasers may nonetheless, by agreement with the Company, purchase securities in such transaction); (b) this Agreement may not be amended, and the observance of any term of this Agreement 

  
 -24- 

 
may not be waived, without the written consent of the holders of at least 75% of the then outstanding shares of Series D’ Preferred Stock then held by the Purchasers (the
“Special Series D’ Vote”), if such amendment or waiver would materially alter the rights of the Series D’ Preferred; (c) this Agreement may not be amended, and the observance of any term
of this Agreement may not be waived, without the written consent of the holders of a majority of the then outstanding shares of Series E Preferred Stock then held by the Purchasers (the “Special Series E
Vote”), if such amendment or waiver would materially alter the rights of the Series E Preferred; and (d) prior to December 31, 2014, Section 3.1(j) of this Agreement may not be amended or terminated and the
observance of any term thereunder may not be waived without, prior to the distribution of Shares by F2 and/or F3 to their respective equity holders, the written consent of F2 and F3 and, after such distribution, the respective equity holders of F2
and/or F3 that received the Shares distributed by F2 and/or F3, as the case may be. For the sake of clarity, neither the Special Series D’ Vote nor the Special Series E Vote shall be required for any amendment or modification to this
Agreement to add additional investors or provide for a new class or series of preferred stock in connection with a financing. The Company shall give prompt written notice of any amendment or termination hereof or waiver hereunder to any party hereto
that did not consent in writing to such amendment, termination or waiver. Any amendment, termination or waiver effected in accordance with this Section 7.6 shall be binding on all parties hereto, even if they do not consent thereto. No waivers
of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision. 

7.7 Pronouns. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine
or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa. 
 7.8 Counterparts; Facsimile
Signatures. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of which together shall constitute one and the same document. This Agreement may be executed by facsimile
signatures or other electronic means. 
 7.9 Section Headings and References. The section headings are for the convenience of the
parties and in no way alter, modify, amend, limit or restrict the contractual obligations of the parties. Any reference in this agreement to a particular section or subsection shall refer to a section or subsection of this Agreement, unless
specified otherwise. 
 7.10 Additional Parties. 

(a) Notwithstanding anything to the contrary contained herein, if the Company issues additional shares of Preferred Stock after the date
hereof to a person or entity not already a party to this Agreement, as a condition to the issuance of such shares the Company shall require that such person or entity become a party to this Agreement by executing and delivering a counterpart
signature page hereto agreeing to be bound by and subject to the terms of this Agreement as an Existing Preferred Stockholder (and if such person or entity purchased Series C’ Preferred Stock, Series D’ Preferred Stock or
Series E Preferred Stock, a Purchaser) hereunder. Each such person or entity shall thereafter be deemed an Existing Preferred Stockholder (and if such person or entity purchased Series C’ Preferred Stock, Series D’ Preferred
Stock or Series E Preferred Stock, a Purchaser) for all purposes under this Agreement. The Company shall have the ability to amend Exhibit B (and Exhibit A, if applicable) to add contact information regarding such
additional Existing Preferred Stockholder without obtaining the consent of any other party to this Agreement. 

  
 -25- 

 (b) In the event that after the date of this Agreement, the Company enters into an agreement
with any person to issue shares of capital stock to such person (other than to a purchaser of Preferred Stock described in Section 7.10(a) above), following which such person shall hold shares of the Company’s capital stock representing on
an as-converted to common stock basis two percent (2%) or more of the Company’s then outstanding capital stock (treating for this purpose all shares of Common Stock issuable upon exercise of or
conversion of outstanding options, warrants or convertible securities, as if exercised and/or converted or exchanged), then the Company shall cause such person, as a condition precedent to entering into such agreement, to become a party to this
Agreement by executing and delivering a counterpart signature page hereto agreeing to be bound by and subject to the terms of this Agreement as a Common Stockholder hereunder. Each such person shall thereafter be deemed a Common Stockholder for all
purposes under this Agreement. The Company shall have the ability to amend Exhibit C to add contact information regarding such additional Common Stockholder without obtaining the consent of any other party to this Agreement. 

7.11 Submission to Jurisdiction. Each of the parties (a) submits to the jurisdiction of any state or federal court sitting in
Boston, Massachusetts or Wilmington, Delaware in any action or proceeding arising out of or relating to this Agreement, (b) agrees that all claims in respect of such action or proceeding may be heard and determined in any such court,
(c) waives any claim of inconvenient forum or other challenge to venue in any such court, (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court and (e) waives any right it may
have to a trial by jury with respect to any action or proceeding arising out of or relating to this Agreement. Each party agrees to accept service of any summons, complaint or other initial pleading made in the manner provided for the giving of
notices in Section 7.4, provided that nothing in this Section 7.11 shall affect the right of any party to serve such summons, complaint or other initial pleading in any other manner permitted by law. 

7.12 Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party under this Agreement, upon
any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or acquiescence to any such breach or default, or
to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under this Agreement or by law
or otherwise afforded to any party, shall be cumulative and not alternative.

WHEREAS, the undersigned desire to amend each of the Agreements in the manner set forth herein. 

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are

representations and warranties of the Company set forth in Sections 3.3(a), 3.3(b) and 3.11(d) hereof shall be true and correct as of the date of such Closing (assuming for this purpose that the references to the “Initial Closing” in such

from and against any and all claims, liabilities or obligations with respect to brokerage or finders’ fees or commissions, or consulting fees in connection with the transactions contemplated by this Agreement asserted by any person on the basis
of any statement or representation alleged to have been made by such indemnifying party. Notwithstanding anything to the contrary set forth herein, the foregoing clause (b) shall not apply to any Fidelity Investor and the Company shall not have
any obligation under the foregoing clause (b) to any Fidelity Investor.” 
 (m) A new Section 7.16 is hereby added to the
Purchase Agreement, to read as follows:

subsidiaries to not, without the prior written consent of Fidelity, use in advertising, or otherwise use publicly, the name of any Fidelity Investor or Fidelity, or any partner or employee of Fidelity or any Fidelity Investor, nor any trade name,
trademark, trade device, service mark, symbol or any abbreviation, contraction or simulation thereof owned by Fidelity, any Fidelity Investor or any of their respective affiliates. The Company further agrees that it shall obtain the written consent
of Fidelity prior to the Company’s issuance of any public statement detailing the purchase of Shares by Fidelity Investors pursuant to this Agreement. Anything herein to the contrary notwithstanding, this Section 7.16 shall not be amended
without the prior written consent of each Fidelity Investor. Notwithstanding the foregoing, this Agreement and any other agreement to which the Company and a Fidelity Investor is a party may be filed by the Company with the Securities and Exchange
Commission.”

references to “Purchase Agreement” in the Investor Rights Agreement shall mean the Purchase Agreement (as defined in the Investor Rights Agreement), as amended by this Amendment. 

  
 38 

 (b) Section 1 of the Investor Rights Agreement is hereby amended by amending and restating
the definition of “Investor Majority” therein to read as follows:

 (c) The first sentence of Section 2.2 of the Investor Rights Agreement is hereby amended and restated in its entirety
to read as follows:

(d) Section 4.3(a) of the Investor Rights Agreement is hereby amended and restated in its entirety to read as follows: 

“(a) The Company shall deliver to (i) each Purchaser and Existing Preferred Stockholder owning, or committing to purchase under the
Purchase Agreement, not less than an aggregate of 5,000,000 shares of Series C’ Preferred Stock, Series D’ Preferred Stock and/or Series E Preferred Stock (subject to appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalization with respect to such shares) and (ii) each Purchaser owning shares of capital stock of the Company and advised or subadvised by Fidelity Management & Research Company or one of its
affiliates (each such Purchaser, a “Fidelity Investor”): 
 (i) within 90 days after the end of each fiscal year of
the Company, an audited balance sheet of the Company as at the end of such year and audited statements of income and of cash flows of the Company for such year, certified by certified public accountants of established national reputation selected by

 (ii) within 45 days after
the end of each fiscal quarter of the Company (other than the fourth quarter), an unaudited balance sheet of the Company as at the end of such quarter, and unaudited statements of income and of cash flows of the Company for such fiscal quarter and
for the current fiscal year to the end of such fiscal quarter; 
 (iii) as soon as practicable, but in any event 30 days before the end of
each fiscal year, a budget and business plan for the next fiscal year, approved by the Board and prepared on a quarterly basis, including projected revenues, expenses and cash positions for such quarters and, promptly after prepared, any other
budgets or revised budgets prepared by the Company; 

  
 39 

 (iv) promptly following the end of each of the first three (3) quarters of each fiscal year

(vi) with reasonable promptness, such other information and data as such Purchaser, Existing Preferred Stockholder or Fidelity Investor may
from time to time reasonably request.” 
 (e) A new Section 4.3(c) is hereby added to the Investor Rights Agreement, to read as
follows: 
 “(c) For so long as the Fidelity Investors own the shares of Series E Preferred Stock purchased by the Fidelity Investors
under the Purchase Agreement, the Company shall give to each Fidelity Investor copies of all notices, minutes, consents and other materials that it provides to the Board at the same time and in the same manner as provided to the Board; provided,
however, that the Fidelity Investors shall agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information so provided; and provided further, that the Company reserves the right to withhold any such information
if (i) the disclosure of such information to a third party could render the Company unable to comply with requirements under the Securities Act or Exchange Act, (ii) access to such information could adversely affect the attorney-client
privilege between the Company and its counsel or result in disclosure of trade secrets or result in a conflict of interest, or (iii) such Fidelity Investor is a competitor of the Company. Notwithstanding anything else in this
Section 4.3(c) to the contrary, the Company may cease providing the information set forth in this Section 4.3(c) during the period starting with the date sixty (60) days before the Company’s good-faith estimate of the date of
submission or filing of a registration statement if it reasonably concludes it must do so to comply with the Commission rules applicable to such registration statement and related offering; provided that the Company’s covenants under this
Section 4.3(c) shall be reinstated at such time as the Company is no longer actively employing its commercially reasonable efforts to cause such registration statement to become effective.” 

(f) Section 7.6 of the Investor Rights Agreement is hereby amended and restated in its entirety to read as follows: 

“7.6 Amendments and Waivers. This Agreement may be amended or terminated and the observance of any term of this Agreement may be
waived with respect to all parties to this Agreement (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company, the Stockholders holding Registrable Shares representing a
majority of the voting power of all Registrable Shares then held by the 

  
 40 

 
Stockholders and the Investor Majority; provided that any amendment, termination or waiver to the terms of Section 2 (or a defined term used therein) that occurs after the closing of the
Initial Public Offering shall instead require the written consent of the Company, the Purchasers holding Registrable Shares representing a majority of all Registrable Shares then held by the Purchasers and the Stockholders holding Registrable Shares
representing a majority of all Registrable Shares then held by the Stockholders. Notwithstanding the foregoing, (a) this Agreement may not be amended or terminated and the observance of any term hereunder may not be waived with respect to any
Purchaser, Qualified Purchaser, Stockholder, Existing Preferred Stockholder or Common Stockholder without the written consent of such Purchaser, Qualified Purchaser, Stockholder, Existing Preferred Stockholder or Common Stockholder, as the case may
be, unless such amendment, termination or waiver applies to all Purchasers, Qualified Purchasers, Stockholders, Existing Preferred Stockholders or Common Stockholders, as the case may be, in the same fashion (it being agreed that a waiver of the
provisions of Section 3 with respect to a particular transaction shall be deemed to apply to all Qualified Purchasers in the same fashion if such waiver does so by its terms, notwithstanding the fact that certain Qualified Purchasers may
nonetheless, by agreement with the Company, purchase securities in such transaction); (b) this Agreement may not be amended, and the observance of any term of this Agreement may not be waived, without the written consent of the holders of at
least 75% of the then outstanding shares of Series D’ Preferred Stock then held by the Purchasers (the “Special Series D’ Vote”), if such amendment or waiver would materially alter the rights of the Series D’
Preferred; (c) this Agreement may not be amended, and the observance of any term of this Agreement may not be waived, without the written consent of the holders of a majority of the then outstanding shares of Series E Preferred Stock then held
by the Purchasers (the “Special Series E Vote”), if such amendment or waiver would materially alter the rights of the Series E Preferred; (d) prior to December 31, 2014, Section 3.1(j) of this Agreement may not be
amended or terminated and the observance of any term thereunder may not be waived without, prior to the distribution of Shares by F2 and/or F3 to their respective equity holders, the written consent of F2 and F3 and, after such distribution, the
respective equity holders of F2 and/or F3 that received the Shares distributed by F2 and/or F3, as the case may be; and (e) any amendment, termination or waiver to the terms of Sections 2.8 and 4.3 (or a defined term used therein) in a manner
adverse to any Fidelity Investor(s) shall require the written consent of the applicable Fidelity Investor(s). For the sake of clarity, neither the Special Series D’ Vote nor the Special Series E Vote shall be required for any amendment or
modification to this Agreement to add additional investors or provide for a new class or series of preferred stock in connection with a financing. The Company shall give prompt written notice of any amendment or termination hereof or waiver
hereunder to any party hereto that did not consent in writing to such amendment, termination or waiver. Any amendment, termination or waiver effected in accordance with this Section 7.6 shall be binding on all parties hereto, even if they do
not consent thereto. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or
provision.” 
  

	 	3.	Amendment of Right of First Refusal and Co-Sale Agreement 

 Acting in accordance with
Section 13.6 of the Right of First Refusal and Co-Sale Agreement, the Company, the Investors (as defined in the Right of First Refusal and Co-Sale Agreement) holding shares of Preferred Stock (as defined in the Right of First Refusal and

  
 41 

 
Co-Sale Agreement) representing a majority of the voting power of all shares of Preferred Stock held by Investors, the Stockholders (as defined in the Right of First Refusal and Co-Sale
Agreement) holding Shares (as defined in the Right of First Refusal and Co-Sale Agreement) representing a majority of the voting power of all Shares then held by the Stockholders and the Investor Majority (as defined in the Right of First Refusal
and Co-Sale Agreement), hereby agree as follows: 
 (a) The first sentence of Section 8.1 of the Right of First Refusal and Co-Sale
Agreement is hereby amended and restated in its entirety to read as follows: 
 “If (i) any person or the Company or any other
entity proposes to engage in a transaction or series of related transactions that (A) would be a Deemed Liquidation Event (as defined in the Company’s Certificate of Incorporation, as may be amended and/or restated from time to time (the
“Company Certificate”)) or (B) involves the sale, to any person or entity or group of affiliated persons or entities, of shares of capital stock representing a majority of the voting power of all outstanding capital
stock of the Company ((A) and (B), a “Sale of the Company”), (ii) such Sale of the Company is approved by the Board and (iii) the holders of shares representing at least sixty-eight percent (68%) of the voting
power of the then outstanding shares of Series C’ Preferred Stock, Series D’ Preferred Stock and Series E Preferred Stock, voting together as a single class (the “Investor Majority”), vote in favor of or consent in
writing to such Sale of the Company (including, without limitation, by means of a proxy or stockholder consent voting in favor of such transaction), then each Stockholder shall be obligated to (a) vote all of his, her or its Shares in favor of
such Sale of the Company, to the extent any such vote is required for the consummation of such Sale of the Company, (b) if applicable, sell, transfer or exchange all of his, her or its Shares in connection with such Sale of the Company on the
same terms as those consented to by such Investors (with appropriate adjustment to reflect the conversion of convertible securities and the preference and priorities of the Preferred Stock) and (c) execute and deliver such instruments of sale,
transfer and exchange and take such other action, including, without limitation, executing any purchase agreement, merger agreement, indemnity agreement, escrow agreement or related documents, as may be reasonably required by the Company in order to
carry out the terms and provisions of this Section 8.1.” 
  

	 	4.	Amendment of Voting Agreement 

 Acting in accordance with Section 10(h) of the
Voting Agreement, the Company, the Stockholders (as defined in the Voting Agreement) holding Shares (as defined in the Voting Agreement) representing a majority of the voting power of all Shares then held by the Stockholders and the Investor
Majority (as defined in the Voting Agreement), hereby agree as follows: 
 (a) The references to “Series E Purchase Agreement” in
the Voting Agreement shall mean the Series E Purchase Agreement (as defined in the Voting Agreement), as amended by this Amendment. 

  
 42 

 (b) Section 1 of the Voting Agreement is hereby amended and restated in its entirety to read
as follows: 
 “1. Voting of Shares.

at nine (9) and to elect as directors: 
 (i) the individual then employed as the Chief Executive Officer of the
Company (the “CEO Director”), which directorship shall initially be held by Roni Mamluk, provided that, if for any reason such individual shall cease to serve as the Chief Executive Officer of the Company, each of the
Stockholders shall promptly vote their respective Shares (A) to remove him or her from the Board if he or she has not resigned from such position and (B) to elect the person who replaces him or her as Chief Executive Officer of the Company
as the new CEO Director; 
 (ii) two (2) individuals designated by MPM BioVentures IV-QP, L.P., for so long as it

and Ansbert K. Gadicke; 
 (iii) one (1) individual designated by Abingworth Bioventures V LP, for so long as it

 (iv) one (1) individual designated by 7 Med Health Ventures LP, for so long as it (together with its affiliated

(v) one (1) individual designated by ARCH Venture Fund VI, L.P., for so long as it (together with its affiliated

(vi) one (1) individual designated by F2 Capital I 2014 Limited, for so long as it (together with its affiliated

(vii) two (2) individuals designated by the holders of shares representing at least sixty-eight percent (68%) of the
voting power of the then outstanding shares of the Company’s Series C’ Convertible Preferred Stock, par value $0.01 per share, the Company’s Series D’ Convertible Preferred Stock, par value $0.01

  
 43 

 
per share (the “Series D’ Preferred Stock”), and Series E Preferred Stock held by the Stockholders, voting together as a single class (collectively, the
“Investor Majority”), who shall initially be John A. Scarlett and David M. Stack.” 
 (b) Section 3 of the
Voting Agreement is hereby amended and restated in its entirety to read as follows: 
 “3. Irrevocable Proxy and Power of
Attorney. Each party to this Agreement hereby constitutes and appoints as the proxies of the party and hereby grants a power of attorney to the President of the Company and a designee of the Investor Majority, and each of them, with full power
of substitution, with respect to the matters set forth in this Agreement, including without limitation, election of persons as members of the Board in accordance with Section 1 hereof and votes to increase authorized shares pursuant to
Section 8 hereof, and hereby authorizes each of them to represent and to vote, if and only if the party (a) fails to vote or (b) attempts to vote (whether by proxy, in person or by written consent), in a manner which is inconsistent
with the terms of this Agreement, all of such party’s Shares in favor of the election of persons as members of the Board determined pursuant to and in accordance with the terms and provisions of this Agreement or the increase of authorized
shares pursuant to and in accordance with the terms and provisions of Section 8 hereof or to take any action necessary to effect Section 8 hereof. Each of the proxy and power of attorney granted pursuant to the immediately preceding
sentence is given in consideration of the agreements and covenants of the Company and the parties in connection with the transactions contemplated by this Agreement and, as such, each is coupled with an interest and shall be irrevocable unless and
until this Agreement terminates or expires pursuant to Section 4 hereof. Each party hereto hereby revokes any and all previous proxies or powers of attorney with respect to the Shares and shall not hereafter, unless and until this Agreement
terminates or expires pursuant to Section 4 hereof, purport to grant any other proxy or power of attorney with respect to any of the Shares, deposit any of the Shares into a voting trust or enter into any agreement (other than this Agreement),
arrangement or understanding with any person, directly or indirectly, to vote, grant any proxy or give instructions with respect to the voting of any of the Shares, in each case, with respect to any of the matters set forth herein. Notwithstanding
anything herein to the contrary, the provisions of this Section 3 shall not be applicable to any Stockholder advised or subadvised by Fidelity Management & Research Company, or one of its Affiliates.” 

3. Miscellaneous. Except as provided herein, each of the Agreements shall remain unchanged and in full force and effect. This Amendment
may be executed in several counterparts by facsimile or other electronic means, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Amendment shall be governed by and construed in
accordance with the General Corporation Law of the State of Delaware, as to matters within the scope thereof, and the internal laws of the Commonwealth of Massachusetts (without reference to the conflicts of law provisions thereof that would require
the application of laws of any other jurisdiction), as to all other matters.
