 (b) Warrant

3. Payment and Exercise. 

(a) Methods of Exercise. The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part and from
time to time, at the election of the Holder, by (a) the surrender of this Warrant (with the notice of exercise substantially in the form attached hereto as Exhibit A duly completed and executed) at the principal office of the Company and
by the payment to the Company, by check, or by wire transfer to an account designated by the Company of an amount equal to the then applicable Exercise Price multiplied by the number of Shares then being purchased (the “Aggregate Purchase
Price”); (b) if in connection with a registered public offering of the Company’s securities, to the extent permitted by the underwriter and the Company, the surrender of this Warrant (with the notice of exercise form attached
hereto as Exhibit B duly completed and executed) at the principal office of the Company together with notice of arrangements reasonably satisfactory to the Company for payment to the Company from the proceeds of the sale of shares to be sold by
the Holder in such public offering of the Aggregate Purchase Price; or (c) exercise of the “net issuance” right provided for in Section 3(b) hereof. The person or persons in whose name(s) any certificate(s) representing Shares of
Applicable Stock shall be issuable upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the Shares represented thereby (and such Shares shall be
deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised. In the event of any exercise of the rights represented by this Warrant, certificates for the Shares so purchased shall
be delivered to the Holder as soon as possible and in any event within thirty (30) days after such exercise and, unless this Warrant has been fully exercised or expired, a new 

  
 -2- 

 
Warrant representing the portion of the Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder as soon as possible and in any
event within such thirty-day period; provided, however, that at such time as the Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, if requested by the Holder, the Company shall cause its
transfer agent to deliver the certificate representing Shares issued upon exercise of this Warrant to a broker or other person (as directed by the Holder exercising this Warrant) within the time period required to settle any trade made by the Holder
after exercise of this Warrant. 
 (b) Right to Convert Warrant into Stock: Net Issuance. 

(i) Net Issuance Right. In addition to and without limiting the rights of the Holder under the terms of this Warrant, the Holder shall
have the right to convert this Warrant or any portion thereof (the “Net Issuance Right”) into shares of Applicable Stock as provided in this Section 3(b) at any time or from time to time during the term of this Warrant.
Upon exercise of the Net Issuance Right with respect to a particular number of shares subject to this Warrant (the “Converted Warrant Shares”), the Company shall deliver to the Holder (without payment by the Holder of any
exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Applicable Stock as is determined according to the following formula: 
  

			
	X =	  	  A - B
		  	     Y

  

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

 No fractional shares shall be issuable upon exercise of the Net Issuance Right, and, if the number of shares to be issued
determined in accordance with the foregoing formula is other than a whole number, the Company shall pay to the Holder an amount in cash equal to the fair market value of the resulting fractional share on the Conversion Date (as hereinafter defined).
For purposes of Section 10 of this Warrant, shares issued pursuant to the Net Issuance Right shall be treated as if they were issued upon the exercise of this Warrant. 

(ii) Exercise of Net Issuance Right. The Net Issuance Right may be exercised by the Holder by the surrender of this Warrant at the
principal office of the Company together with a written statement (which may be in the form of Exhibit A or Exhibit B hereto) specifying that the Holder thereby intends to exercise the Net Issuance Right and indicating the number of shares
subject to this Warrant which are being surrendered (referred to in Section 3(b)(i) hereof as the Converted Warrant Shares) in exercise of the Net Issuance Right. Such conversion shall be effective upon receipt by the Company of this Warrant
together with the aforesaid written statement, or on such later date as is specified therein (the “Conversion Date”), and, at the election of the Holder, may be made contingent upon the closing of the sale of the
Company’s Common Stock to the public in a public offering (a “Public Offering”) pursuant to a Registration Statement under the Securities Act of 1933, amended (the “Act”). Certificates for the
shares issuable upon exercise of the Net Issuance Right and, if applicable, a new warrant evidencing the balance of the shares remaining subject to this Warrant, shall be issued as of the Conversion Date and shall be delivered to the Holder within
thirty (30) days following the Conversion Date. 

  
 -3- 

 (iii) Determination of Fair Market Value. For purposes of this Section 3(b),
“fair market value” of a share of Applicable Stock (which shall be Common Stock if the Applicable Stock has been converted into Common Stock) as of a particular date (the “Determination Date”) shall mean: 

(1) If the Net Issuance Right is exercised in connection with and contingent upon a Public Offering, and if the Company’s Registration
Statement relating to such Public Offering (“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “price to the public” specified in the final prospectus
with respect to such offering. 
 (2) If the Net Issuance Right is not exercised in connection with and contingent upon a Public Offering,
then as follows: 
 (A) If traded on a securities exchange, then the fair market value shall be the average of the closing
prices of the Common Stock on such exchange over the five trading days immediately prior to the Determination Date; 
 (B)
If traded on the Nasdaq Stock Market or other over-the-counter system, then the fair market value shall be the average of the closing bid prices of the Common Stock over the five trading days immediately prior to the Determination Date; and 

(C) If there is no public market, then fair market value shall be determined in good faith by the Company’s Board of
Directors. 
 In making a determination under clauses (A) or (B) above, if on the Determination Date, five trading days have not passed since the
Company’s initial Public Offering then the fair market value of the Common Stock shall be the average closing prices or closing bid prices, as applicable, for the shorter period beginning on and including the date of the initial Public Offering
and ending on the trading day prior to the Determination Date (or if such period includes only one trading day the closing price or closing bid price, as applicable, for such trading day). If closing prices or closing bid prices are no longer
reported by a securities exchange or other trading system, the closing price or closing bid price shall be that which is reported by such securities exchange or other trading system at 4:00 p.m. New York City time on the applicable trading day. 

(c) Exercise Prior to Expiration. To the extent this Warrant is not previously exercised as to all of the Shares subject hereto, and if
the fair market value of one share of the Applicable Stock is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised pursuant to Section 3(b) (even if not surrendered) immediately before its
expiration, including but not limited to expiration pursuant to Section 2. For purposes of such automatic exercise, the fair market value of one share of the Applicable Stock upon such expiration shall be determined pursuant to
Section 3(b)(iii). To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 3(c), the Company agrees to promptly notify the Holder of the number of Shares, if any, the Holder is to
receive by reason of such automatic exercise. 
 4. Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the
exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all preemptive rights and taxes, liens and charges with respect to the issuance
thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant,
a sufficient number of shares of its Applicable Stock to provide for the exercise of the rights represented by this Warrant and, while the Applicable Stock is convertible preferred stock, a sufficient number of shares of its Common Stock to provide
for the conversion of the Applicable Stock into Common Stock.

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

(a) Reclassification or Merger. In case of any reclassification or change of securities of the class issuable upon exercise of this
Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in case of any merger of the Company with or into another entity (other than a
merger with another entity in which the Company is the acquiring and the surviving entity and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant), or in case of any sale of all or
substantially all of the assets of the Company, the Company, or such successor or purchasing corporation, as the case may be, shall duly execute and deliver to the Holder a new Warrant (in form and substance satisfactory to the Holder), or the
Company shall make appropriate provision without the issuance of a new Warrant, so that the Holder shall have the right to receive upon exercise of this Warrant, at a total purchase price not to exceed that payable upon the exercise of the
unexercised portion of this Warrant, and in lieu of the shares of Applicable Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such
reclassification, change, merger or sale by a holder of the number of shares of Applicable Stock then purchasable under this Warrant. The provisions of this Section 5(a) shall similarly apply to successive reclassifications, changes, mergers
and sales. 
 (b) Subdivision or Combination of Shares. If the Company at any time while this Warrant remains outstanding and
unexpired shall subdivide or combine its outstanding shares of Applicable Stock, the Exercise Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision and
the Exercise Price shall be proportionately increased and the number of Shares issuable hereunder shall be proportionately decreased in the case of a combination. 

(c) Stock Dividends and Other Distributions. If the Company at any time while this Warrant is outstanding and unexpired shall
(i) pay a dividend with respect to Applicable Stock payable in Applicable Stock, then the Exercise Price shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that
price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Applicable Stock outstanding immediately prior to such
dividend or distribution, and (B) the denominator of which shall be the total number of shares of Applicable Stock outstanding immediately after such dividend or distribution; or (ii) make any other distribution with respect to Applicable
Stock (except any distribution specifically provided for in Sections 5(a) and 5(b)), then, in each such case, provision shall be made by the Company such that the Holder shall receive upon exercise of this Warrant a proportionate share of any
such dividend or distribution as though it were the holder of the Applicable Stock as of the record date fixed for the determination of the shareholders of the Company entitled to receive such dividend or distribution. 

(d) Adjustment of Number of Shares. Upon each adjustment in the Exercise Price, the number of Shares of Applicable Stock purchasable
hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Exercise Price by a fraction, the numerator of which shall be the Exercise
Price immediately prior to such adjustment and the denominator of which shall be the Exercise Price immediately thereafter. 
 (e)
Antidilution Rights. The other antidilution rights applicable to the Shares of Applicable Stock purchasable hereunder are set forth in the Company’s Certificate of Incorporation, as amended through

  
 -5- 

 
the Warrant Date, a true and complete copy of which is attached hereto as Exhibit C (the “Charter”); provided, however, that any waiver of such antidilution rights
obtained by the Company from the holders of such Applicable Stock in accordance with the applicable provisions of the Charter which apply to all Shares of Applicable Stock shall apply to and be binding upon the Holder whether or not such waiver was
sought or obtained from the Holder. The Company shall provide the Holder with any restatement, amendment, modification or waiver of the Charter promptly after the same has been made. 

6. Notice of Adjustments. Whenever the Exercise Price or the number of Shares purchasable hereunder shall be adjusted pursuant to
Section 5 hereof, the Company shall make a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was
calculated, and the Exercise Price and the number of Shares purchasable hereunder after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the Holder. In addition, whenever the conversion price or
conversion ratio of the Applicable Stock shall be adjusted, the Company shall make a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method
by which such adjustment was calculated, and the conversion price or ratio of the Applicable Stock after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the Holder. 

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

8. Compliance with Act; Disposition of Warrant or Shares of Applicable Stock. 

(a) Compliance with Act. The Holder, by acceptance hereof, agrees that this Warrant, and the shares of Applicable Stock to be issued
upon exercise hereof and any Common Stock issued upon conversion thereof are being acquired for investment and that the Holder will not offer, sell or otherwise dispose of this Warrant, or any shares of Applicable Stock to be issued upon exercise
hereof or any Common Stock issued upon conversion thereof except under circumstances which will not result in a violation of the Act or any applicable state securities laws. Upon exercise of this Warrant, unless the Shares being acquired are
registered under the Act and any applicable state securities laws or an exemption from such registration is available, the Holder shall confirm in writing that the shares of Applicable Stock so purchased (and any shares of Common Stock issued upon
conversion thereof) are being acquired for investment and not with a view toward distribution or resale in violation of the Act and shall confirm such other matters related thereto as may be reasonably requested by the Company, including the
Holder’s status as an “accredited investor” as such term is defined in Rule 501 of Regulations D promulgated under the Act. This Warrant and all shares of Applicable Stock issued upon exercise of this Warrant (unless registered under
the Act and any applicable state securities laws) shall be stamped or imprinted with a legend in substantially the following form: 
 “THE SECURITIES
EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN
OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED, (iii) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE
PROVISIONS OF SECTION 8 OF THE WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY.” 
 Said legend shall be removed by the
Company, upon the request of the Holder, at such time as the restrictions on the transfer of the applicable security shall have terminated. 

  
 -6- 

 (b) Disposition of Warrant or Shares. With respect to any offer, sale or other disposition
of this Warrant or any shares of Applicable Stock acquired pursuant to the exercise of this Warrant prior to registration of such Warrant or shares, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner
thereof, together with a written opinion of counsel, if requested by the Company, or other evidence, if reasonably satisfactory to the Company, to the effect that such offer, sale or other disposition may be effected without registration or
qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such shares of Applicable Stock and indicating whether or not under the Act certificates for this Warrant or such shares of
Applicable Stock to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory opinion
of counsel or other evidence, the Company, as promptly as practicable but no later than fifteen (15) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of this Warrant or such shares
of Applicable Stock, all in accordance with the terms of the notice delivered to the Company; provided, however, in any such transfer, if applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of
this Warrant as if an original holder hereof. If a determination has been made pursuant to this Section 8(b) that the opinion of counsel or other evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder
promptly with details thereof after such determination has been made. Notwithstanding the foregoing, this Warrant or such shares of Applicable Stock may, as to such federal laws, be offered, sold or otherwise disposed of in accordance with
Rule 144 or 144A under the Act, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 or 144A have been satisfied.
Each certificate representing this Warrant or the shares of Applicable Stock thus transferred (except a transfer pursuant to Rule 144 or 144A after the expiration of applicable holding periods) shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions. 
 (c) Applicability of Restrictions. Neither any
restrictions of any legend described in this Warrant nor the requirements of Section 8(b) above shall apply to any transfer of, or grant of a security interest in, this Warrant (or the Applicable Stock or Common Stock obtainable upon exercise
thereof) or any part hereof (i) to a partner of the Holder if the Holder is a partnership or to a member of or other holder of an interest in the Holder if the Holder is a limited liability company, (ii) to a partnership of which the
Holder is a partner or to a limited liability company of which the Holder is a member or other holder of an interest, or (iii) to any affiliate of the Holder if the Holder is a corporation; provided, however, in any such transfer,
if applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of this Warrant as if an original holder hereof. 

9. Rights as Shareholders; Information. No Holder, as a holder of this Warrant, shall be entitled to vote or receive dividends or be
deemed the holder of Applicable Stock or any other securities of the Company which may at any time be issuable upon the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the
rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to receive dividends or subscription rights or otherwise until this Warrant shall have
been exercised and the Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. Notwithstanding the foregoing, the Company will transmit to the Holder such information, documents and reports as are generally
distributed to the holders of any class or series of the securities of the Company concurrently with the distribution thereof to the shareholders.

 Exhibit 4.6 

THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD, OR TRANSFERRED EXCEPT IN COMPLIANCE THEREWITH. 
 THE SECURITIES ISSUABLE UPON EXERCISE HEREOF ARE ALSO
SUBJECT TO ADDITIONAL RESTRICTIONS, INCLUDING RESTRICTIONS ON TRANSFER, AS SET FORTH IN A STOCKHOLDERS AGREEMENT, A COPY OF WHICH WILL BE FURNISHED BY TV2 HOLDING COMPANY UPON REQUEST AND WITHOUT CHARGE. 

WARRANT TO PURCHASE SHARES OF PREFERRED STOCK 

Issue Date: February 2, 2012 

FOR VALUE RECEIVED, TV2 Holding Company, a Delaware corporation (the
“Company”), certifies that [the Holder] (the “Holder”), is entitled, subject to the terms and conditions hereof, to purchase from the Company up to that number of shares of Warrant Stock (as defined
below) equal to 25% of the outstanding principal balance of the Note (as defined below) divided by the Exercise Price (as defined below) (such shares, the “Warrant Shares”), at a price per share equal to the Exercise Price.
By acceptance of this warrant (the “Warrant”), Holder agrees to all the terms and conditions hereof. 
 1.
Purchase Agreement. This Warrant belongs to a series of warrants of like tenor and effect (collectively, the “Warrants”) issued pursuant to that certain Note and Warrant Purchase Agreement (the “Purchase
Agreement”) dated as of February 2, 2012 by and among the Company and the investors listed on the Schedule of Investors thereto (collectively, the “Investors”). Capitalized terms used but not defined herein
shall have the meanings ascribed to them in the Purchase Agreement. Pursuant to the Purchase Agreement, the Company issued and sold to Holder a convertible promissory note (the “Note”). 

2. Warrant Stock; Exercise Price. This Warrant shall be exercisable for shares of the preferred stock of the Company of the same class
and series as may be sold to investors for cash or cancellation of indebtedness in the next Qualified Financing or Non-Qualified Financing (each as defined in the Note), as the case may be (such preferred stock, the “Warrant
Stock”), at an exercise price equal to the lowest price per share paid by investors in such Qualified Financing or Non-Qualified Financing, as the case may be (such price, the “Exercise Price”), provided,
however, that prior to (or in the absence of) a Qualified Financing or a Non-Qualified Financing, this Warrant shall be exercisable for shares of the Series C Preferred Stock of the Company at an exercise price equal to the Series C Issue Price
(as defined in the Certificate of Incorporation of the Company, as amended (the “Charter”)) per share (and the terms “Warrant Stock” and “Exercise Price” shall instead refer thereto). 

3. Warrant Certificate. Upon completion of a Qualified Financing or a Non-Qualified Financing, as the case may be, the Company shall
execute and deliver a certificate to the Holder in substantially the form of Exhibit A attached hereto (the “Applicable Stock Certificate”), specifying the number of shares of Warrant Stock and the Exercise Price. Any failure
by the Company in delivering, or failure of Holder in receiving, the Applicable Stock Certificate shall not limit or otherwise affect the rights of Holder to exercise the Warrant in accordance with the terms hereof. 

4. Exercise Period. This Warrant may be exercised at any time during the period (the “Exercise Period”)
commencing on the date hereof and ending on the 7th anniversary thereof, unless sooner terminated in accordance with the provisions hereof. Holder acknowledges that any exercise for the shares of Series C Preferred Stock is subject to
Section 13 below. 

 5. Method of Exercise. Subject to Section 13 below, this Warrant may be exercised in
whole or in part by delivery of the following to the Company at its address set forth on the signature page hereto (or at such other address as it may designate by notice in writing to Holder): (i) an executed Notice of Exercise in the form
attached hereto as Exhibit B; (ii) payment in United States dollars by check or wire transfer in readily available funds of the aggregate exercise price of the Warrant Shares to be purchased (unless exercised pursuant to Section 6 hereof);
and (iii) this Warrant. 
 6. Net Exercise. Notwithstanding the foregoing, if on the date of exercise of this Warrant the fair
market value of one Warrant Share (as determined in good faith by the Board of Directors) exceeds the Exercise Price, then in lieu of payment in cash or by check for the Warrant Shares to be purchased, Holder may elect to receive that number of
Warrant Shares as is determined using the following formula: 
  

							
		 	X =	 	Y * (A – B)	  	
		 		 	A	  	

  

					
		 	where:	  	X = the number of Warrant Shares to be issued to Holder;
			
		 		  	Y = the number of Warrant Shares with respect to which Holder is exercising its purchase right under this Warrant;
			
		 		  	A = the fair market value of one Warrant Share on the date of exercise; and
			
		 		  	B = the Exercise Price

 7. Rights Upon Exercise. All shares issued upon exercise of this Warrant shall be validly issued, fully
paid and non-assessable, shall be free from all taxes, liens, and charges with respect to the issuance thereof (other than any encumbrances created by or imposed upon Holder), and shall have the same rights, preferences and privileges, and be
subject to the same restrictions, as the Warrant Stock generally. In addition to the covenant set forth in Section 5.2 of the Purchase Agreement, Holder acknowledges and agrees that, upon exercise of this Warrant, Holder shall be required to
execute and deliver such other documents (including by way of illustration and without limitation, stock purchase, stockholders, investor rights, voting and/or co-sale agreements) as may be required to grant Holder the same rights, and subject
Holder to the same duties and obligations, as Holders of Warrant Stock generally. 
 8. Securities Laws. Notwithstanding anything
herein to the contrary, the Company’s obligation to issue shares of stock to any Holder pursuant hereto is expressly conditioned on compliance of such issuance with applicable federal and state securities laws, without registration or
qualification thereunder. 
 9. No Fractional Shares; Share Certificates. No fractional shares shall be issued upon exercise of this
Warrant. If upon exercise of this Warrant a fractional share results, the Company shall pay Holder the cash value of that fractional share based on the Exercise Price. The certificates representing any shares purchased upon exercise of this Warrant
shall be delivered to Holder as soon as practicable after surrender of this Warrant to the Company. 
 10. Adjustment of Exercise Price
and Number of Shares. In the event of any change in the outstanding Warrant Stock by reason of a stock dividend, stock split, recapitalization, reclassification, combination or exchange of shares, separation, reorganization, liquidation or the
like (each, an “Adjustment Event”), the securities purchasable upon exercise of this Warrant and the Exercise Price 

  
 -2- 

 
shall be correspondingly adjusted to give Holder, upon exercise of this Warrant for the same aggregate Exercise Price, the aggregate number, class and kind of shares or other securities that
Holder would have owned had Holder exercised the Warrant prior to such Adjustment Event and continued to hold the shares so received until after such Adjustment Event. Any adjustment pursuant to this Section 10 shall become effective at the
close of business on the effective date of such Adjustment Event; provided, however, that if a record date is fixed for such Adjustment Event, then the effective date of such adjustment shall be such record date. The form of this Warrant need
not be changed because of any adjustment pursuant to this Section 10. 
 11. Antidilution Rights. The other antidilution rights
applicable to the Warrant Stock purchasable hereunder are set forth in the Charter; provided, however, that any waiver of such antidilution rights obtained by the Company from the holders of the Company’s preferred stock in accordance
with the applicable provisions of the Charter shall apply to and be binding upon the Holder whether or not such waiver was sought or obtained from the Holder. 

12. Automatic Exercise. At any time during the Exercise Period, subject to Section 13 below, in the event of any Liquidation Event
(as defined in the Charter but excluding clause (i) of such definition), this Warrant shall be deemed automatically exercised in whole pursuant to the formula and procedures set forth in Section 6 hereof. 

13. Amendment of Charter. Holder acknowledges the covenant set for in Section 5.1 of the Purchase Agreement whereby, following the
Maturity Date (as defined in the Note), the Company undertakes to amend the Charter, upon request of the Supermajority Investors, to authorize such additional shares of Series C Preferred Stock as would be sufficient to effect the exercise of this
Warrant hereunder. 
 14. No Stockholder Rights. Nothing contained herein shall be construed as conferring upon Holder or any other
person any rights, preferences or privileges as a stockholder of the Company, until and only to the extent that this Warrant is exercised for equity securities of the Company. 

15. Governing Law. This Warrant and the rights and obligations of the parties hereunder shall be governed by and construed under the
laws of the State of California, without regard to its choice of law or conflicts of law provisions. 
 16. Attorneys’ Fees. In
any legal proceeding arising out of or related to this Warrant, the prevailing party shall be entitled to reasonable attorneys’ fees and out-of-pocket costs, in addition to any other relief to which such party may be entitled. 

17. Entire Agreement. This Warrant, together with the Purchase Agreement and the Note and any documents delivered pursuant hereto or
thereto, constitutes the full and complete understanding and agreement of the parties with respect to the subject matter hereof, and supersedes any prior agreements between the parties with respect thereto. 

18. Severability. If any provision hereof is held unenforceable in any respect, such provision shall be invalid only to the extent of
such unenforceability, without invalidating the remainder of such provision or any other provision of this Warrant. 
 19. No Implied
Waiver. No failure to exercise, delay in exercising or partial exercise of any right or remedy hereunder shall operate as a waiver of any provision of this Warrant. No waiver of any provision of this Warrant shall operate as a waiver of any
other provision (whether or not similar), nor shall it operate as a continuing waiver, unless so provided in writing by the waiving party. 

  
 -3- 

 20. Remedies Cumulative. All remedies afforded to any party hereto, either under this
Warrant or by law or otherwise, shall be cumulative and not alternative. 
 21. Counterparts. This Warrant may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which together shall constitute a single instrument. Facsimile signatures hereto shall be valid. 

22. Headings. The headings used in this Warrant are for convenience only and are not to be considered in construing this Warrant. 

23. Amendment; Waiver. This Warrant may be modified, amended or terminated, and any provision hereof waived, either generally or in a
particular instance and either retroactively or prospectively, only by the written consent of the Company and the Supermajority Investors, provided, however, that any party may by written consent waive performance of any obligation owing to
it hereunder, or agree to accept alternatives to such performance, without the consent of any other party. 
 24. Assignment. Except
as provided in Section 4.1 of the Purchase Agreement, neither party may voluntarily or by operation of law assign this Warrant or any rights or obligations hereunder without the prior written consent of the other party. Any attempted assignment
in violation of this provision shall be null and void. 
 25. Successors and Assigns. Except as otherwise provided herein, the terms
and conditions of this Warrant, and any consents or stipulations hereunder, shall inure to the benefit of and be binding upon the respective successors and assigns of each party. 

26. Third Party Beneficiaries. Except as otherwise provided herein, nothing in this Warrant, express or implied, is intended to confer
upon any third party any rights, remedies, obligations or liabilities. 
 27. Notices. All notices required or permitted hereunder
shall be given in accordance with the notice provisions of the Purchase Agreement. 
 28. Further Assurances. Each party agrees to
execute and deliver such other documents and to take such other actions as may reasonably be necessary to give full effect to the purposes of this Warrant and the terms and conditions hereof.

NOTICE OF EXERCISE 
  

			
	To:	  	[            ] (the “Company”)
		
	Attention:	  	Chief Executive Officer

 The undersigned, holder of the attached Warrant (the “Warrant”), hereby elects to purchase
                 shares of the              Stock (the “Shares”) of the Company. 

The undersigned (check one): 
  

	 	 ̈	Tenders herewith payment of the aggregate exercise price of the Shares, together with any applicable transfer taxes thereon. 

  

	 	 ̈	Elects to purchase the Shares pursuant to the net exercise provision of the Warrant, and shall tender payment of any applicable transfer taxes thereon. 

Please issue a certificate or certificates representing said Shares in the name of the undersigned. 

The undersigned represents and warrants as follows: 

(i) The undersigned is acquiring the Shares for the undersigned’s own account for investment purposes, not as a nominee or agent, and not
with a view to the sale or distribution of any part thereof. The undersigned has no present intention of selling, transferring, granting any participation in, or otherwise distributing any of the Shares, and does not presently have reason to
anticipate a change in such intention. The undersigned has no contract, agreement, undertaking or arrangement with any person to sell, transfer, grant participation in or otherwise distribute any of the Shares. The undersigned understands that the
Company is issuing the Shares in reliance upon the undersigned’s representations herein. 
 (ii) The undersigned has received all the
information that it has requested from the Company and that it considers necessary or appropriate for deciding whether to acquire the Shares. The undersigned has had an opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Shares and to obtain any additional information from the Company necessary to verify the accuracy of the information given to the undersigned. 

(iii) The undersigned acknowledges that investment in the Shares involves a high degree of risk. The undersigned has such knowledge and
experience in financial and business matters that it is capable of evaluating the merits and risks of its investment in the Shares and of protecting its own interests in connection with this transaction. The undersigned is able, without materially
impairing its financial condition, to hold the Shares for an indefinite period of time and to suffer a complete loss of its investment in the Shares. The undersigned is an “accredited investor” within the meaning of Rule 501(a) under the
Securities Act of 1933, as amended (the “Securities Act”), as presently in effect. 
 (iv) The undersigned
understands that the Shares have not been registered under the Securities Act and, therefore, the Shares cannot be resold unless they are registered under the Securities Act or an 

 
exemption from registration is available. The undersigned understands that the Company is under no obligation to register any of the Shares. The undersigned understands that no public market now
exists for the Shares, and that it is uncertain whether such a public market will ever exist. 
 (v) The undersigned understands that the
Shares are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving any 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. The undersigned is familiar with Rule 144 under the Securities Act, as presently in effect, and understands the resale limitations imposed
thereby and by the Securities Act. 
 (vi) The undersigned agrees not to make any disposition of all or any part of the aforesaid Shares
unless and until there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with said registration statement, or there is an exemption available under the
Securities Act and, if requested by the Company, the undersigned has provided the Company with an opinion of counsel satisfactory to the Company, stating that such registration is not required. 

(vii) If any registration of Warrant Stock shall be effected in connection with an underwritten public offering, the undersigned shall not
effect any public sale or distribution, including any sale pursuant to Rule 144, of any Shares or other security of the Company (except as part of such public offering) during the period beginning 14 days prior to the effective date of the
applicable registration statement until the earlier of (i) such time as the Company and the lead managing underwriter shall agree and (ii) 180 calendar days (such period, the “Lock-Up Period” for the applicable
registration statement); provided, however, that such 180-day period may be extended for up to 18 days to permit compliance with FINRA Rule 2711(f)(4) upon the request of any managing underwriter. The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restriction until the end of the applicable market standoff period. The undersigned agrees to execute a market standoff agreement with such underwriters in customary form consistent
with the provisions hereof. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all stockholders of the Company subject to such agreements, based on
the number of shares subject to such agreements.
