CHARGEPOINT, INC.

WARRANT TO PURCHASE SHARES OF COMMON STOCK

 

Pursuant to the terms
of that certain Series [_________] Preferred Stock and Warrant Purchase Agreement (as such may be amended from time to time, the
“Purchase Agreement”) dated as of [_________], among the Company, the Holder (as defined below), and certain other
Investors, this Warrant (the “Warrant”) is issued to [_________] (the “Holder”) by ChargePoint, Inc., a
Delaware corporation (the “Company”). Capitalized terms not defined herein shall have the meaning set forth in the
Purchase Agreement.

 

1. Purchase
of Shares.

 

(a) Number
of Shares. Subject to the terms and conditions set forth herein, the Holder is entitled, upon surrender of this Warrant at
the principal office of the Company (or at such other place as the Company shall notify the Holder in writing), to purchase from
the Company up to [_________] of fully paid and nonassessable shares of the Company’s Common Stock, par value $0.0001 per
share (the “Common Stock”).

 

(b) Exercise
Price. The exercise price for the shares of Common Stock issuable pursuant to this Section 1 (the “Shares”) shall
be $[_________] per share (the “Exercise Price”). The Shares and the Exercise Price shall be subject to adjustment
pursuant to Section 7 hereof.

 

2. Exercise
Period. This Warrant shall be exercisable, in whole or in part, during the term commencing on the date hereof and ending at
5:00 p.m. Pacific Time on [insert date that is ten years after issuance of Warrant] (the “Exercise Period”);
provided, however, that this Warrant shall no longer be exercisable and shall become null and void upon the consummation
of a Corporate Transaction, subject to the automatic exercise provisions of Section 3(d) hereof. In the event of a Corporate Transaction,
the Company shall notify the Holder at least ten (10) days prior to the consummation of such Corporate Transaction. As used in
this Warrant, “Corporate Transaction” shall mean a Liquidation Event (as defined in the Company’s Amended and
Restated Certificate of Incorporation, as may be amended from time to time) and “Initial Public Offering” shall mean
the first closing of a public offering of the Company’s Common Stock registered under the Securities Act of 1933, as amended
(the “Securities Act”).

 

    

     

    

 

3. Method
of Exercise.

 

(a) While
this Warrant remains outstanding and exercisable in accordance with Section 2 above, the Holder may exercise, in whole or in part,
the purchase rights evidenced hereby. Such exercise shall be effected by:

 

(i) the
surrender of the Warrant, together with a duly executed copy of the Notice of Exercise attached hereto, to the Secretary of the
Company at its principal office (or at such other place as the Company shall notify the Holder in writing); and

 

(ii) the
payment to the Company of an amount equal to the aggregate Exercise Price for the number of Shares being purchased.

 

(b) Each
exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which this
Warrant is surrendered to the Company as provided in Section 3(a) above. At such time, the person or persons in whose name or names
any certificate for the Shares shall be issuable upon such exercise as provided in Section 3(c) below shall be deemed to have become
the holder or holders of record of the Shares represented by such certificate.

 

(c) As
soon as practicable after the exercise of this Warrant in whole or in part, and in any event within twenty (20) days thereafter,
the Company at its expense will cause to be issued in the name of, and delivered to, the Holder, or as such Holder (upon payment
by such Holder of any applicable transfer taxes) may direct:

 

(i) a
certificate or certificates for the number of Shares to which such Holder shall be entitled, and

 

(ii) in
case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on
the face or faces thereof for the number of Shares equal to the number of such Shares described in this Warrant minus the number
of such Shares purchased by the Holder upon all exercises made in accordance with Section 3(a) above or Section 4 below.

 

(d) Notwithstanding
the provisions of Section 2, if the holder has not exercised this Warrant prior to the closing of a Corporate Transaction, this
Warrant shall automatically be deemed to be exercised in full in the manner set forth in Section 4, without any further action
on behalf of the Holder immediately prior to such closing.

 

4. Net
Exercise. In lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal to the value of this Warrant
(or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with notice
of such election (a “Net Exercise”). A Holder who Net Exercises shall have the rights described in Sections 3(b) and
3(c) hereof, and the Company shall issue to such Holder a number of Shares computed using the following formula:

 

	X= 	Y (A - B)	 
	A	 

 

Where

 

		X =	The number of Shares to be issued to the Holder.

 

    2

     

    

 

		Y =	The number of Shares purchasable under this Warrant or, if only a portion of the Warrant is being
exercised, the portion of the Warrant being exercised (at the date of such calculation).

 

		A =	The fair market value of one (1) Share (at the date of such calculation).

 

		B =	The Exercise Price (as adjusted to the date of such calculation).

 

In the event that this
Warrant is exercised pursuant to this Section 4 in connection with the Initial Public Offering, the fair market value per Share
shall be the per share offering price to the public of the Initial Public Offering. In the event that this Warrant is exercised
pursuant to this Section 4 in connection with a Corporate Transaction, the fair market value per share shall be the amount of proceeds
one Share would be entitled to receive in connection with such Corporate Transaction (assuming full exercise of this Warrant and
all similar warrants issued pursuant to the Purchase Agreement prior to the consummation of such Corporate Transaction). In the
event that this Warrant is exercised pursuant to this Section 4 after the Common Stock is listed for trading on the Nasdaq Stock
Market’s National Market or the New York Stock Exchange, the fair market value of a Share shall mean the average of the closing
prices of the Shares (or equivalent shares of Common Stock underlying this Warrant) quoted on any exchange or electronic securities
market on which the Shares (or equivalent shares of Common Stock underlying the Warrant) are listed, as published in The Wall
Street Journal for the ten (10) trading days prior to the date of determination of fair market value (or such shorter period
of time during which such Shares were traded on such exchange). In the event that this Warrant is not exercised in connection with
the Initial Public Offering or a Corporate Transaction or after the Common Stock is listed for trading on the Nasdaq Stock Market’s
National Market or the New York Stock Exchange, the fair market value shall be the price per Share that the Company could obtain
from a willing buyer for Shares sold by the Company from authorized but unissued Shares, as such prices shall be determined in
good faith by the Company’s Board of Directors.

 

5. Representations
and Warranties of the Holder. In connection with the transactions provided for herein, the Holder hereby represents and warrants
to the Company that:

 

(a) Authorization.
Holder represents that it has full power and authority to enter into this Warrant. This Warrant constitutes the Holder’s
valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (i) applicable bankruptcy,
insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights and (ii) laws relating
to the availability of specific performance, injunctive relief or other equitable remedies.

 

(b) Purchase
Entirely for Own Account. The Holder acknowledges that this Warrant is entered into by the Company in reliance upon such Holder’s
representation to the Company that the Warrant and the Shares (collectively, the “Securities”) will be acquired for
investment for the Holder’s own account, not as a nominee or agent, and not with a view to the resale or distribution of
any part thereof, and that the Holder has no present intention of selling, granting any participation in or otherwise distributing
the same. The Holder further represents that the Holder does not have any contract, undertaking, agreement, or arrangement with
any person to sell, transfer or grant participations to such person or to any third person, with respect to the Securities.

 

(c) Disclosure
of Information. The Holder acknowledges that it has received all the information it considers necessary or appropriate for
deciding whether to acquire the Securities. The Holder further represents that it has had an opportunity to ask questions and receive
answers from the Company regarding the terms and conditions of the offering of the Securities.

 

    3

     

    

 

(d) Investment
Experience. The Holder is an investor in securities of companies in the development stage and acknowledges that it is able
to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business
matters that it is capable of evaluating the merits and risks of the investment in the Securities. If other than an individual,
the Holder also represents it has not been organized solely for the purpose of acquiring the Securities.

 

(e) Accredited
Investor. The Holder is an “accredited investor” within the meaning of Rule 501 of Regulation D, as presently in
effect, as promulgated by the Securities and Exchange Commission (the “SEC”) under the Securities Act.

 

(f) Restricted
Securities. The Holder understands that the Securities are characterized as “restricted securities” under the federal
securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that
under such laws and applicable regulations such securities may be resold without registration under the Securities Act, only in
certain limited circumstances. In this connection, the Holder represents that it is familiar with Rule 144, as presently in effect,
as promulgated by the SEC under the Securities Act (“Rule 144”), and understands the resale limitations imposed thereby
and by the Securities Act.

 

(g) Further
Limitations on Disposition. Without in any way limiting the representations set forth above, the Holder further agrees not
to make any disposition of all or any portion of the Securities unless and until the transferee has agreed in writing for the benefit
of the Company to be bound by the terms of this Warrant, including, without limitation, this Section 5, Section 11, Section 12,
and:

 

(i) there
is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is
made in accordance with such registration statement; or

 

(ii) the
Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement
of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished
the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration
of such shares under the Securities Act. It is agreed that the Company will not require opinions of counsel for transactions made
pursuant to Rule 144 except in extraordinary circumstances.

 

(h) Legends.
It is understood that the Securities may bear the following legend:

 

“THESE SECURITIES HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, OR OTHERWISE
TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION
OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER
SUCH ACT.”

 

6. State
Commissioners of Corporations. THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS WARRANT HAS NOT BEEN QUALIFIED WITH
THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY
PART OF THE CONSIDERATION FOR SUCH SECURITIES PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT
FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS WARRANT
ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

 

    4

     

    

 

7. Adjustment
of Exercise Price and Number of Shares. The number and kind of Shares purchasable upon exercise of this Warrant and the Exercise
Price shall be subject to adjustment from time to time as follows:

 

(a) Subdivisions,
Combinations and Other Issuances. If the Company shall at any time after the issuance but prior to the expiration of this Warrant
subdivide its Common Stock, by split-up or otherwise, or combine its Common Stock, or issue additional shares of its Preferred
Stock or Common Stock as a dividend with respect to any shares of its Common Stock, the number of Shares issuable on the exercise
of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately
decreased in the case of a combination. Appropriate adjustments shall also be made to the Exercise Price payable per share, but
the aggregate Exercise Price payable for the total number of Shares purchasable under this Warrant (as adjusted) shall remain the
same. Any adjustment under this Section 7(a) shall become effective at the close of business on the date the subdivision or combination
becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of
such dividend.

 

(b) Reclassification,
Reorganization and Consolidation. In case of any reclassification, capital reorganization or change in the capital stock of
the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 7(a) above), then,
as a condition of such reclassification, reorganization or change, lawful provision shall be made, and duly executed documents
evidencing the same from the Company or its successor shall be delivered to the Holder, so that the Holder shall have the right
at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this
Warrant, the kind and amount of shares of stock and other securities or property receivable in connection with such reclassification,
reorganization or change by a holder of the same number and type of securities as were purchasable as Shares by the Holder immediately
prior to such reclassification, reorganization or change. In any such case appropriate provisions shall be made with respect to
the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to any shares of
stock or other securities or property deliverable upon exercise hereof, and appropriate adjustments shall be made to the Exercise
Price per Share payable hereunder, provided the aggregate Exercise Price shall remain the same.

 

(c) Notice
of Adjustment. When any adjustment is required to be made in the number or kind of shares purchasable upon exercise of the
Warrant, or in the Exercise Price, the Company shall promptly notify the Holder of such event and of the number of Shares or other
securities or property thereafter purchasable upon exercise of this Warrant.

 

8. No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor on the basis of the Exercise
Price then in effect.

 

9. No
Stockholder Rights. Prior to exercise of this Warrant, the Holder shall not be entitled to any rights of a stockholder with
respect to the Shares, including (without limitation) the right to vote such Shares, receive dividends or other distributions thereon,
exercise preemptive rights or be notified of stockholder meetings, and, except as otherwise provided in this Warrant, such Holder
shall not be entitled to any stockholder notice or other communication concerning the business or affairs of the Company.

 

    5

     

    

 

10. Registration
Rights. The Warrant Shares issuable upon exercise of this Warrant shall be deemed “Registrable Securities” for
all purposes under that certain Amended and Restated Investors’ Rights Agreement, by and among the Company and the persons
and entities listed thereto (as may be amended from time to time) and shall be subject to the rights and covenants therein.

 

11. Voting
Agreement. Any Shares issued upon exercise of this Warrant shall be subject to the rights and obligations of that certain Amended
and Restated Voting Agreement between the Company and the parties thereto, dated on or about [_________] (the “Voting Agreement”)
and prior to any transfer of this Warrant or the Shares issued upon exercise of this Warrant to a transferee that is not a party
to the Voting Agreement, such transferee shall agree in writing for the benefit of the Company to be bound by the terms of the
Voting Agreement.

 

12. 
“Market Stand-Off” Agreement. If requested by the Company and an underwriter of Common Stock (or other securities
of the Company), the Holder shall not sell or otherwise transfer or dispose of any shares of the Common Stock acquired through
the exercise of this Warrant (other than those included in the registration) during the 180 day period (which period may be extended
to 214 days pursuant to the applicable rules issued by the Financial Industry Regulatory Authority) following the effective date
of a registration statement of the Company filed under the Securities Act, provided that such agreement shall only apply to the
Initial Public Offering. The foregoing provisions of this Section 12 shall not apply to the sale of any shares to an underwriter
pursuant to an underwriting agreement and shall only be applicable to the Holder if all officers and directors and holders of at
least 1% of capital stock the Company enter into similar agreements. The underwriters in connection with the Company’s Initial
Public Offering are intended third party beneficiaries of this Section 12 and shall have the right, power and authority to
enforce the provisions hereof as though they were a party hereto. The obligations described in this Section 12 shall not apply
to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in
the future, or a registration relating solely to an SEC Rule 145 transaction on Form S-4 or similar forms that may be promulgated
in the future. The Company may impose stop-transfer instructions with respect to the shares (or securities) subject to the foregoing
restriction until the end of such 180 day period, or, if applicable, 214 day period.

 

The Holder agrees that
a legend reading substantially as follows shall be placed on all certificates representing all Shares of the Holder (and the shares
or securities of every other person subject to the restriction contained in this Section 12):

 

THE SHARES REPRESENTED BY THIS CERTIFICATE
ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS (WHICH MAY BE EXTENDED TO 214 DAYS) FOLLOWING THE EFFECTIVE DATE OF A REGISTRATION
STATEMENT OF THE COMPANY FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND
THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. SUCH LOCK-UP PERIOD
IS BINDING ON TRANSFEREES OF THESE SHARES.

 

13. Transfer
of Warrant. Subject to compliance with applicable federal and state securities laws and any other contractual restrictions
between the Company and the Holder contained herein (including, without limitation, Section 5, Section 11 and Section 12),
this Warrant and all rights hereunder are transferable in whole or in part by the Holder to any person or entity upon written notice
to the Company. Within a reasonable time after the Company’s receipt of an executed Assignment Form in the form attached
hereto, the transfer shall be recorded on the books of the Company upon the surrender of this Warrant, properly endorsed, to the
Company at its principal offices, and the payment to the Company of all transfer taxes and other governmental charges imposed on
such transfer. In the event of a partial transfer, the Company shall issue to the new holders one (1) or more appropriate new warrants.
Notwithstanding the foregoing, the Holder agrees that this Warrant shall not be transferred to any of the Company’s competitors
as such is reasonably determined by the Company and that prior to the Initial Public Offering, the shares issued upon exercise
of this Warrant shall not be transferred to such a competitor.

 

    6

California residents entered into and to be performed entirely within California.

and Assigns. The terms and provisions of this Warrant shall inure to the benefit of, and be binding upon, the Company and the
holders hereof and their respective successors and assigns.

shall constitute one and the same instrument.

 

17. Titles
and Subtitles. The titles and subtitles used in this Warrant are used for convenience only and are not to be considered in
construing or interpreting this Warrant.

 

18. Notices.
All notices and other communications given or made pursuant hereto shall be in writing and shall be deemed effectively given: (a)
upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal
business hours of the recipient, and if not so confirmed, then on the next business day, (c) five (5) days after having been sent
by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally
recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent
to the respective parties at the addresses set forth on the signature pages hereto (or at such other addresses as shall be specified
by notice given in accordance with this Section 18):

 

19. 
Finder’s Fee. Each party represents that it neither is nor will be obligated for any finder’s fee or commission
in connection with this transaction. The Holder agrees to indemnify and to hold harmless the Company from any liability for any
commission or compensation in the nature of a finder’s fee (and the costs and expenses of defending against such liability
or asserted liability) for which the Holder or any of its officers, partners, employees or representatives is responsible. The

of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost,
stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether
or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

 

22. Entire
Agreement; Amendments and Waivers. This Warrant and any other documents delivered pursuant hereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects hereof and thereof. Nonetheless, any term of this Warrant
may be amended and the observance of any term of this Warrant may be waived (either generally or in a particular instance and either
retroactively or prospectively), with the written consent of the Company and the Holder; or if this Warrant has been assigned in
part, by the holders or rights to purchase a majority of the shares originally issuable pursuant to this Warrant.

 

23. Severability.
If any provision of this Warrant is held to be unenforceable under applicable law, such provision shall be excluded from this Warrant
and the balance of the Warrant shall be interpreted as if such provision were so excluded and shall be enforceable in accordance
with its terms.

WARRANT TO PURCHASE

 

SHARES OF PREFERRED STOCK OF

 

COULOMB TECHNOLOGIES, INC.

 

(Void after April 30, 2021)

 

This certifies that
[      ], or assigns (“Holder”), for value received, is entitled to purchase from COULOMB TECHNOLOGIES,
INC., a Delaware corporation (“Company”), the Applicable Number (hereinafter defined) of fully paid and nonassessable
shares of, at Holder’s option, either (i) Company’s Series B preferred stock (the “Series B Preferred Stock”)
or (ii) the Next Round Stock (hereinafter defined) (the Series B Preferred Stock or the Next Round Stock, as applicable, “Preferred
Stock”) for cash at a purchase price per share hereinafter determined (the “Stock Purchase Price”). Holder may
also exercise this Warrant on a cashless or “net issuance” basis as described in Section 1(b) below, and this Warrant
shall be deemed to have been exercised in full on such basis on the Expiration Date, to the extent not fully exercised prior to
such date. This Warrant is issued in connection with the Loan and Security Agreement of even date herewith (as amended, restated
and supplemented from time to time, the “Loan Agreement”), between Company, as borrower, and Holder’s subsidiary,
[ ], as lender (“Lender”). Capitalized terms used herein and not otherwise defined in
this Warrant shall have the meaning(s) ascribed to them in the Loan Agreement, unless the context would otherwise require. The
“Applicable Number” of shares purchasable hereunder shall be the number obtained by dividing (X) $110,000 by (Y) the
Stock Purchase Price.

 

The Stock Purchase
Price shall be equal to (i) if Holder chooses for this Warrant to be exercisable for Series B Preferred Stock, the lesser of (A)
$0.2143 per share and (B) the lowest price per share at which Company most recently sold (as of any date of determination) shares
of its Series B Preferred Stock (subject to any adjustment for any splits, dividends or distributions since the date of such sale),
or (ii) if Holder chooses for this Warrant to be exercisable for Next Round Stock, the Next Round Price (hereinafter defined).

 

The “Next Round
Price” is the lowest price per share paid by an investor for Company’s equity securities issued in the Next Round (hereinafter
defined) (the “Next Round Stock”), including for this purpose the value of all consideration given by an investor for
such equity securities. The “Next Round” means the next bona fide round of equity financing after the date hereof in
which Company sells or issues shares of its securities, and includes any options, warrants, or other convertible securities or
similar consideration issued or delivered to investors in connection with such equity financing in such round; provided that the
Next Round excludes any extensions to Company’s Series B Preferred Stock round of financing.

 

This Warrant may be
exercised at any time or from time to time up to and including 5:00 p.m. (Pacific time) on April 30, 2021 (the “Expiration
Date”), upon surrender to Company at its principal office at 1692 Dell Avenue, Campbell, CA 95008 (or at such other location
as Company may advise Holder in writing) of this Warrant properly endorsed with the Form of Subscription attached hereto duly completed
and signed and upon payment in cash or by check of the aggregate Stock Purchase Price for the number of shares for which this Warrant
is being exercised determined in accordance with the provisions hereof The Stock Purchase Price and the number of shares purchasable
hereunder are subject to further adjustment as provided in Section 4 of this Warrant.

 

    

     

    

 

This Warrant is subject
to the following terms and conditions:

 

1. Exercise;
Issuance of Certificates; Payment for Shares.

 

(a) Unless
an election is made pursuant to clause (b) of this Section 1, this Warrant shall be exercisable at the option of Holder, at any
time or from time to time, on or before the Expiration Date for all or any portion of the shares of Preferred Stock (but not for
a fraction of a share) which may be purchased hereunder for the Stock Purchase Price multiplied by the number of shares to be purchased.
In the event, however, that pursuant to Company’s Certificate of Incorporation, as amended, an event causing automatic conversion
of Company’s Preferred Stock shall have occurred prior to the exercise of this Warrant, in whole or in part, then this Warrant
shall be exercisable for the number of shares of Common Stock of Company into which the Preferred Stock not purchased upon any
prior exercise of this Warrant would have been so converted (and, where the context requires, reference to “Preferred Stock”
shall be deemed to be or include such Common Stock, as may be appropriate). Company agrees that the shares of Preferred Stock purchased
under this Warrant shall be and are deemed to be issued to Holder hereof as the record owner of such shares as of the close of
business on the date on which the form of subscription shall have been delivered and payment made for such shares. Subject to the
provisions of Section 2, certificates for the shares of Preferred Stock so purchased, together with any other securities or property
to which Holder hereof is entitled upon such exercise, shall be delivered to Holder hereof by Company at Company’s expense
within a reasonable time after the rights represented by this Warrant have been so exercised. Except as provided in clause (b)
of this Section 1, in case of a purchase of less than all the shares which may be purchased under this Warrant, Company shall cancel
this Warrant and execute and deliver a new Warrant or Warrants of like tenor for the balance of the shares purchasable under this
Warrant surrendered upon such purchase to Holder hereof within a reasonable time. Each stock certificate so delivered shall be
in such denominations of Preferred Stock as may be requested by Holder hereof and shall be registered in the name of such Holder
or such other name as shall be designated by such Holder, subject to the limitations contained in Section 2.

 

(b) Holder,
in lieu of exercising this Warrant by the cash payment of the Stock Purchase Price pursuant to clause (a) of this Section 1, may
elect, at any time on or before the Expiration Date, to surrender this Warrant and receive that number of shares of Preferred Stock
computed using the following formula:

 

X — Y(A — B)

A

 

Where: X = the number of shares of Preferred Stock

(c) For
purposes of Section 1(b), “Per Share Price” means:

 

(i) If
this Warrant is exercised on the date of Company’s initial public offering of Common Stock, and if Company’s registration

Share Price shall be the product of (A) the initial “Price to Public” of the Common Stock specified in the final prospectus
with respect to the offering, and (B) the number of shares of Common Stock into which each share of Preferred Stock exercised is
convertible at the date of calculation.

to the date of the Holder’s election hereunder and (B) the number of shares of Common Stock into which each share of Preferred
Stock exercised is convertible on such date.

 

(iii) If
neither (i) nor (ii) is applicable, the Per Share Price shall be determined in good faith by the Board of Directors of Company
based on relevant facts and circumstances at the time of the net exercise under Section 1(b), including in the case of a Change
of Control (as defined in Section 4.3 hereof) the consideration receivable by the holders of the Preferred Stock in such Change
of Control and the liquidation preference (including any declared but unpaid dividends), if any, then applicable to the Preferred
Stock.

or sold under Rule 144) be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any

under the Securities Act was in effect with respect to such securities at the time of issuance thereof) except pursuant to (i)
an effective registration statement under the Securities Act, (ii) Rule 144 under the Securities Act (or any other rule under the
Securities Act relating to the disposition of securities), or (iii) an opinion of counsel, reasonably satisfactory to counsel for
Company, that an exemption from such registration is available.

 

3. Shares
to be Fully Paid; Reservation of Shares. Company covenants and agrees that all shares of Preferred Stock which may be issued
upon the exercise of the rights represented by this Warrant will, upon issuance, be duly authorized, validly issued, fully paid
and nonassessable and free from all preemptive rights of any stockholder and free of all taxes, liens and charges with respect
to the issue thereof. Company further covenants and agrees that during the period beginning on the date the Company first issues
Next Round Stock (unless otherwise requested by Holder in connection Holder’s exercise of this Warrant for shares of Series
B Preferred Stock), Company will at all times have authorized and reserved, for the purpose of issue or transfer upon exercise
of the subscription rights evidenced by this Warrant, a sufficient number of shares of authorized but unissued Preferred Stock,
or other securities and property, when and as required to provide for the exercise of the rights represented by this Warrant. Company
will take all such action as may be necessary to assure that such shares of Preferred Stock may be issued as provided herein without
violation of any applicable law or regulation, or of any requirements of any domestic securities exchange upon which the Preferred
Stock may be listed. Company will not take any action which would result in any adjustment of the Stock Purchase Price (as described
in Section 4 hereof) (i) if the total number of shares of Preferred Stock issuable after such action upon exercise of all outstanding
warrants, together with all shares of Preferred Stock then outstanding and all shares of Preferred Stock then issuable upon exercise
of all options and upon the conversion of all convertible securities then outstanding, would exceed the total number of shares
of Preferred Stock then authorized by Company’s Certificate of Incorporation, (ii) if the total number of shares of Common
Stock issuable after such action upon the conversion of all such shares of Preferred Stock together with all shares of Common Stock
then outstanding and then issuable upon exercise of all options and upon the conversion of all convertible securities then outstanding
would exceed the total number of shares of Common Stock then authorized by Company’s Certificate of Incorporation or (iii)
if the par value per share of the Preferred Stock would exceed the Stock Purchase Price.

 

4. Adjustment
of Stock Purchase Price and Number of Shares. The Stock Purchase Price and the number of shares purchasable upon the exercise
of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events described in this Section
4.

 

4.1 Subdivision
or Combination of Stock. In case Company shall at any time subdivide its outstanding shares of Preferred Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such subdivision shall be proportionately reduced, and
conversely, in case the outstanding shares of Preferred Stock of Company shall be combined into a smaller number of shares, the
Stock Purchase Price in effect immediately prior to such combination shall be proportionately increased.

 

4.2 Dividends
in Preferred Stock, Other Stock, Property, Reclassification. If at any time or from time to time the holders of Preferred Stock
(or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become
entitled to receive, without payment therefor,

 

(a) Preferred
Stock, or any shares of stock or other securities whether or not such securities are at any time directly or indirectly convertible
into or exchangeable for Preferred Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing
by way of dividend or other distribution,

 

(b) any
cash paid or payable otherwise than as a cash dividend, or

 

(c) Preferred
Stock or other or additional stock or other securities or property (including cash) by way of spin off, split-up, reclassification,
combination of shares or similar corporate rearrangement, (other than shares of Preferred Stock issued as a stock split, adjustments
in respect of which shall be covered by the terms of Section 4.1 above),

 

    4

     

    

 

then and in each such case, Holder hereof
shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Preferred Stock receivable
thereupon, and without payment of any additional consideration therefore, the amount of stock and other securities and property
(including cash in the cases referred to in clauses (b) and (c) above) which such Holder would hold on the date of such exercise
had it been the holder of record of such Preferred Stock as of the date on which holders of Preferred Stock received or became
entitled to receive such shares and/or all other additional stock and other securities and property.

 

4.3 Change
of Control or IPO. In the event of (i) a Change of Control (as hereinafter defined) or (ii) the consummation of a sale of Company’s
securities pursuant to a registration statement filed by Company under the Securities Act, in connection with the first firm commitment
underwritten offering of Company’s securities to the general public that occurs after the date this Warrant is issued (“IPO”),
this Warrant shall be automatically exchanged for a number of shares of Company’s securities, such number of shares being
equal to the maximum number of shares issuable pursuant to the terms hereof (after taking into account all adjustments described
herein) had Holder elected to exercise this Warrant immediately prior to the closing of such Change of Control or IPO and purchased
all such shares pursuant to the cash exercise provision set forth in Section 1(a) hereof (as opposed to the cashless exercise provision
set forth in Section 1(b)). Company acknowledges and agrees that Holder shall only be required to make an additional payment for
such shares in an amount as shall equal the aggregate par value, as determined in accordance with the Company’s Charter (as
defined below), with respect to the shares so issued; provided that such payment shall be deemed to have been made pursuant to
Section 1(b) of this Warrant using such par value as the “Stock Purchase Price” solely for purposes of the calculation
in Section 1(b). “Change of Control” shall mean any sale, license, or other disposition of all or substantially all
of the assets of Company, or any reorganization, consolidation, or merger of Company where the holders of Company’s securities
before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction.
This Warrant shall terminate upon Holder’s receipt of the number of shares of Company’s equity securities described
in this Section 4.3.

 

4.4 Sale
or Issuance Below Purchase Price; “Pay-to-Play” Exemption.

 

(a) The
other antidilution rights applicable to the shares of Preferred Stock purchasable hereunder as of the date hereof are set forth
in Company’s Certificate of Incorporation, as amended through the date hereof (the “Charter”). The antidilution
and other rights applicable to the shares of series Preferred Stock purchasable hereunder set forth in the Charter may be restated,
amended, modified or waived in any manner so long as such amendment, modification or waiver is effected consistent with the requirements
of the Charter and of the Delaware General Corporation Law, each as then in effect.

 

(b) In
the event that any “pay to play” terms or conditions (i.e. terms or conditions that require a holder of Company’s
Preferred Stock to purchase securities in a future round of equity or debt financing or else lose the benefit of antidilution protection
applicable to the shares of Preferred Stock issuable upon the exercise of this Warrant or have such shares of Preferred Stock automatically
convert to common stock or convert to another class and series of Company’s capital stock) in Company’s Charter, as
amended from time to time, or other agreement among the Company and its stockholders are triggered in connection with the consummation
of a Down Round (hereinafter defined) or otherwise after the date hereof, then in such event, this Warrant shall automatically
adjust to provide Holder with the same securities and/or rights that Holder would have received had Holder participated in the
Down Round to its full pro rata share with respect to the Preferred Stock issuable upon exercise of this Warrant (e.g., if this
Warrant provides for the purchase of Series B Preferred Stock, and Company after the date hereof consummates a Down Round in which
those holders of Series B Preferred Stock who participate to their full pro rata share in such Down Round become entitled to exchange
such Series B Preferred Stock for Series B-1 Preferred Stock and those holders of Series B Preferred Stock who do not participate
to their full pro rata share will have their Series B Preferred Stock converted into Common Stock, then this Warrant would automatically
adjust to provide the right to purchase Series B-1 Preferred Stock instead of Common Stock). “Down Round” means either
(i) any non-public offering of securities of Company after the original date of issuance of this Warrant at a price per share lower
than the Stock Purchase Price then in effect, or (ii) any. non-public offering of Company’s debt securities after the original
date of issuance of this Warrant which requires a holder .of Company’s Preferred Stock to purchase such debt securities or
have such shares of Preferred Stock automatically convert to common stock or convert to another class and series of Company’s
capital stock.

 

    5

     

    

 

(c) If
in connection with a Down Round, the holders of a requisite percentage of shares of Preferred Stock waive any anti-dilution protections
that would otherwise have been available to such stockholders under the Charter on account of the issuance of securities in the
Down Round, Company shall afford Holder the opportunity to purchase up to that number of shares of equity securities of Company
to be sold through the Down Round as will enable Holder to own or acquire immediately after completion of the Down Round the same
percentage of the equity securities of Company (on a fully diluted basis) as Holder owned and/or had the right to purchase under
this Warrant immediately prior to commencement of the Down Round offering. In this regard, Company shall provide written notice
to Holder reasonably in advance of a proposed Down Round, which notice shall state, to the extent then known by Company, the number
and type of shares of equity securities proposed to be sold through the Down Round and the per share price, and shall establish
a deadline, not less than 20 days after the giving of such notice, by which Holder must deliver its written election to purchase
shares in the Down Round. The per share price payable by Holder in the Down Round shall be the same per share price payable by
the lead investor in the Down Round. If Company fails timely to afford Holder the opportunity to participate in the Down Round
in the foregoing manner, then Holder shall be entitled, upon conversion of the Preferred Stock issuable under this Warrant, to
the full benefit of any and all antidilution protections that were waived by the holders of Preferred Stock in connection with
the Down Round.

 

4.5 Notice
of Adjustment. Upon any adjustment of the Stock Purchase Price, and/or any increase or decrease in the number of shares purchasable
upon the exercise of this Warrant Company shall give written notice thereof, by first class mail, postage prepaid, addressed to
the registered holder of this Warrant at the address of such holder as shown on the books of Company. The notice, which may be
substantially in the form of Exhibit “A” attached hereto, shall be signed by Company’s chief financial officer
and shall state the Stock Purchase Price resulting from such adjustment and the increase or decrease, if any, in the number of
shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation
and the facts upon which such calculation is based.

 

4.6 Other
Notices. If at any time:

 

(a) Company
shall declare any cash dividend upon its Preferred Stock;

 

(b) Company
shall declare any dividend upon its Preferred Stock payable in stock or make any special dividend or other distribution to the
holders of its Preferred Stock;

 

(c) Company
shall offer for subscription pro rata to the holders of its Preferred Stock any additional shares of stock in connection with a
Down Round or additional shares of stock of any class or other rights;

 

(d) there
shall be any capital reorganization or reclassification of the Preferred Stock of Company, or consolidation or merger of Company
with, or sale of all or substantially all of its assets to, another entity, which would result in the payment of a liquidation
preference to the holders of the Preferred Stock;

 

(e) there
shall be a voluntary or involuntary dissolution, liquidation or winding-up of Company; or

 

(f) Company
shall take or propose to take any other action, notice of which is actually provided to holders of the Preferred Stock;

 

    6

     

    

 

then, in any one or more of said cases,
Company shall give, by first class mail, postage prepaid, addressed to Holder of this Warrant at the address of such Holder as
shown on the books of Company, (i) at least 20 days’ prior written notice (or such shorter period as shall represent the
amount of notice provided to the other holders of the Company’s Preferred Stock) of the date on which the books of Company
shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote
in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, or
other action and (ii) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation
or winding-up, or other action, at least 20 days’ written notice (or such shorter period as shall represent the amount of
notice provided to the other holders of the Company’s Preferred Stock) of the date when the same shall take place. Any notice
given in accordance with the foregoing clause (i) shall also specify, in the case of any such dividend, distribution or subscription
rights, the date on which the holders of Preferred Stock shall be entitled thereto. Any notice given in accordance with the foregoing
clause (ii) shall also specify the date on which the holders of Preferred Stock shall be entitled to exchange their Preferred Stock
for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up, or other action as the case may be.

 

4.7 Certain
Events. If any change in the outstanding Preferred Stock of Company or any other event occurs as to which the other provisions
of this Section 4 are not strictly applicable or if strictly applicable would not fairly effect the adjustments to this Warrant
in accordance with the essential intent and principles of such provisions, then the Board of Directors of Company shall make in
good faith an adjustment in the number and class of shares issuable under this Warrant, the Stock Purchase Price and/or the application
of such provisions, in accordance with such essential intent and principles, so as to protect such purchase rights as aforesaid.
The adjustment shall be such as will give Holder of this Warrant upon exercise for the same aggregate Stock Purchase Price the
total number, class and kind of shares as Holder would have owned had this Warrant been exercised prior to the event and had Holder
continued to hold such shares until after the event requiring adjustment.

 

5. Issue
Tax. The issuance of certificates for shares of Preferred Stock upon the exercise of this Warrant shall be made without charge
to Holder of this Warrant for any issue tax in respect thereof; provided, however, that Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than
that of the then Holder of this Warrant being exercised.

 

6. Closing
of Books. Company will at no time close its transfer books against the transfer of this Warrant or of any shares of Preferred
Stock issued or issuable upon the exercise of this Warrant in any manner which interferes with the timely exercise of this Warrant.

 

7. No
Voting or Dividend Rights; Limitation of Liability. Nothing contained in this Warrant shall be construed as conferring upon
Holder hereof the right to vote or to consent as a stockholder in respect of meetings of stockholders for the election of directors
of Company or any other matters or any rights whatsoever as a stockholder of Company. No dividends or interest shall be payable
or accrued in respect of this Warrant or the interest represented hereby or the shares purchasable hereunder until, and only to
the extent that, this Warrant shall have been exercised. No provisions hereof, in the absence of affirmative action by Holder to
purchase shares of Preferred Stock, and no mere enumeration herein of the rights or privileges of Holder hereof, shall give rise
to any liability of such Holder for the Stock Purchase Price or as a stockholder of Company, whether such liability is asserted
by Company or by its creditors.

 

8. Intentionally
Omitted.

 

9. Registration
Rights. Upon execution of that certain First Amendment to Amended and Restated Investors’ Rights Agreement, dated as
of even date herewith, Holder hereof shall be entitled, with respect to the shares of Preferred Stock issued upon exercise hereof
or the shares of Common Stock or other securities issued upon conversion of such Preferred Stock as the case may be, to all of
the registration rights set forth in the Amended and Restated Investors’ Rights Agreement dated as of December 21, 2009 (the
“Rights Agreement”), to the same extent and on the same terms and conditions as possessed by the investors thereunder
with the following exceptions and clarifications: (i) Holder will have no right to initiate a demand registration under Section
1.3 of the Rights Agreement; (ii) Holder will be subject to the same provisions regarding indemnification as contained in the Rights
Agreement; and (iii) the registration rights are freely assignable by Holder of this Warrant in connection with a permitted transfer
of this Warrant or the shares issuable upon exercise hereof, so long as the transferee executes such amendment to the Rights Agreement
as shall be reasonably requested by the Company. Company shall take such action as may be reasonably necessary to assure that the
granting of such registration rights to Holder does not violate the provisions of the Rights Agreement or any of Company’s
charter documents or rights of prior grantees of registration rights.

 

    7

Holder hereof shall continue to be entitled after such exercise in accordance with this Warrant; provided, that the failure of

rights.
