 [FORM OF SERIES [B] [C] [D] WARRANT] 
 STEREOTAXIS, INC. 
 WARRANT TO PURCHASE COMMON STOCK 
 Warrant No.:                      
 Number of Shares of Common Stock:                     

 Date of Issuance: December     , 2008 (“Issuance Date”) 
 Stereotaxis, Inc., a Delaware corporation (the “Company”), hereby certifies that,
for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [            ] [            ],
the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon surrender of this
Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”), at any time or times on or after the date hereof but not after 11:59 p.m., New
York time, on the Expiration Date (as defined below), [                    ]
([                    ])1 fully paid
nonassessable shares of Common Stock (as defined below) (the “Warrant Shares”). This Warrant is one of the Warrants to purchase Common Stock (the “SPA Warrants”) issued pursuant to Section 1 of that certain
Securities Purchase Agreement, dated as of December     , 2008 (the “Subscription Date”), by and among the Company and the investors (individually, a “Buyer” and collectively, the
“Buyers”) referred to therein (the “Securities Purchase Agreement”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 16. 
 1. EXERCISE OF WARRANT. 
 (a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder at any time or times on or after the
date hereof, in whole or in part, by (i) delivery of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant and (ii) (A) payment to
the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash or by wire transfer of immediately
available funds or (B) by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the original Warrant in 

  

  

	 1
	 [INSERT IN SERIES B WARRANT] [Insert a number of shares equal to pro rata portion of $9,990,000 divided by $4.65]

 [INSERT IN SERIES C & D WARRANT] [Insert number that is equal to the difference between (x) 5 million divided by
$3.25 and (y) 50% of the number of Common Shares (as defined in the Securities Purchase Agreement) issued to the Holder pursuant to the Securities Purchase Agreement] 

 
order to effect an exercise hereunder, but shall deliver the original Warrant within five (5) Business Days after exercising the Warrant in full.
Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number
of Warrant Shares. On or before the first (1st) Business Day following the date on which the Company has received each of the Exercise Notice
and the Aggregate Exercise Price (or notice of a Cashless Exercise) (the “Exercise Delivery Documents”), the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the
Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the third (3rd) Trading Day following the
date on which the Company has received all of the Exercise Delivery Documents (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company
(“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s
balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch by overnight courier to the address as
specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon
delivery of the Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant
Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and
the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three
(3) Business Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such exercise under this
Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall
be rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. [INSERT IN SERIES C & D WARRANT ONLY]
[NOTWITHSTANDING ANY PROVISION OF THIS WARRANT TO THE CONTRARY, NO MORE THAN THE MAXIMUM ELIGIBILITY NUMBER OF WARRANT SHARES SHALL BE EXERCISABLE HEREUNDER.] 
 (b) Exercise Price. For purposes of this Warrant, “Exercise
Price” means $[            ]2, subject to adjustment as provided herein.

 (c) Company’s Failure to Timely Deliver Securities. If the Company shall fail
for any reason or for no reason to issue to the Holder within three (3) Trading Days of receipt of the Exercise Delivery Documents, a certificate for the number of shares of Common Stock to which the Holder is entitled and register such shares
of Common Stock on the Company’s share register or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise hereunder or
pursuant to the Company’s obligation pursuant to clause (ii) below, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by
the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s request
and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including actual brokerage commissions, if any) for the shares of Common Stock so purchased (the
“Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Warrant Shares or credit such Holder’s balance account with DTC) shall terminate, or (ii) promptly
honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares or credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the
Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Weighted Average Price on the date of exercise. 
 (d) Cashless Exercise. Notwithstanding anything contained herein to the contrary, if the Registration Statement (as defined in the Securities Purchase Agreement) covering the issuance of the Warrant Shares that
are the subject of the Exercise Notice by the Holder pursuant to the 1933 Act (the “Unavailable Warrant Shares”) is not available for the issuance of such Unavailable Warrant Shares, the Holder may only exercise this Warrant in
whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares
of Common Stock determined according to the following formula (a “Cashless Exercise”): 
  

					
	Net Number =	  	(A x B) - (A x C)	  	
		  	B	  	

 For purposes of the foregoing formula: 
  

					
	A	 	=	 	the total number of shares with respect to which this Warrant is then being exercised.
			
	B	 	=	 	the Weighted Average Price of the shares of Common Stock (as reported by Bloomberg) on the date immediately preceding the date of the Exercise Notice.

  

 - 3 - 

					
	C	 	=	 	the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

 (e) Disputes. In the case of a dispute as to the determination of the
Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 12. 
 (f) Limitations on Exercises. 
 (i) Beneficial Ownership. The Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together
with such Person’s affiliates) would beneficially own in excess of 4.99% the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing
sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such
sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (x) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (y) exercise or
conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants)
subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”). For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding
shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission (“SEC”) as the case may be,
(2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request
of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined
after giving effect to the conversion or exercise of securities of the Company, including the SPA Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice
to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% 

  

 - 4 - 

 
specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the other holder and not to any Holder of SPA Warrants. The
provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f)(i) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. 
 (ii) Principal Market Regulation. The Company shall not be obligated to issue any shares of Common Stock upon exercise of this Warrant and no Buyer shall be entitled to receive any shares of Common Stock if the
issuance of such shares of Common Stock would exceed that number of shares of Common Stock which the Company may issue upon exercise of the SPA Warrants or otherwise without breaching the Company’s obligations under the rules or
regulations of any applicable Eligible Market (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its shareholders as required by the applicable rules of
the Eligible Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the
Required Holders. Until such approval or written opinion is obtained, no Buyer shall be issued in the aggregate, upon exercise of any SPA Warrants, shares of Common Stock in an amount greater than the product of the Exchange Cap multiplied by a
fraction, the numerator of which is the total number of shares of Common Stock underlying the SPA Warrants issued to such Buyer pursuant to the Securities Purchase Agreement on the Issuance Date and the denominator of which is the aggregate number
of shares of Common Stock underlying the SPA Warrants issued to the Buyers pursuant to the Securities Purchase Agreement on the Issuance Date (with respect to each Buyer, the “Exchange Cap Allocation”). In the event that any Buyer
shall sell or otherwise transfer any of such Buyer’s SPA Warrants, the transferee shall be allocated a pro rata portion of such Buyer’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such
transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of SPA Warrants shall exercise all of such holder’s SPA Warrants into a number of shares of Common Stock
which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be
allocated to the respective Exchange Cap Allocations of the remaining holders of SPA Warrants on a pro rata basis in proportion to the shares of 

  

 - 5 - 

 
Common Stock underlying the SPA Warrants then held by each such holder. [INSERT IN SERIES C & D WARRANTS ONLY] [In the event that the Company is
prohibited from issuing any Warrant Shares for which an Exercise Notice has been received as a result of the operation of this Section 1(f)(ii), the Company shall pay cash in exchange for cancellation of such Warrant Shares, at a price per
Warrant Share equal to the difference between the Closing Sale Price and the Exercise Price as of the date of the attempted exercise.] 
 (g) Insufficient Authorized Shares. If at any time while this Warrant remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its
obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common Stock equal to (the “Required Reserve Amount”) the number of shares of Common Stock as shall from time to time be necessary to
effect the exercise of all of this Warrant then outstanding (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an
amount sufficient to allow the Company to reserve the Required Reserve Amount for this Warrant then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized
Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common
Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to
cause its board of directors to recommend to the stockholders that they approve such proposal. 
 (h) [INSERT IN SERIES B
WARRANT ONLY] [Fees Payable by the Company. The Holder acknowledges and understands that the Company has agreed to pay Deutsche Bank Securities Inc. certain fees in the event that this Warrant is exercised pursuant to this Section 1
or otherwise under the terms hereof.] 
 2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and
the number of Warrant Shares shall be adjusted from time to time as follows: 
 (a) [INSERT IN SERIES C & D WARRANT]
[Intentionally omitted.] [INSERT IN SERIES B WARRANT] [Adjustment upon Issuance of shares of Common Stock. If and whenever on or after the Subscription Date the Company issues or sells, or in accordance with this Section 2 is
deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock deemed to have been issued by the Company in
connection with any Excluded Securities) for a consideration per share (the “New Issuance Price”) less than a price (the “Applicable Price”) equal to the Exercise Price in effect immediately prior to such issue or
sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after 

  

 - 6 - 

 
such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount equal to the New Issuance Price. For purposes of determining the
adjusted Exercise Price under this Section 2(a), the following shall be applicable: 
 (i) Issuance of Options. If the Company in
any manner grants any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any
such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For
purposes of this Section 2(a)(i), the “lowest price per share for which one share of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities issuable upon exercise of
any such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option
and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common
Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities. 
 (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for
which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the
time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(a)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or
exchange thereof” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon
conversion, exercise or exchange of such Convertible Security. No further adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of
such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(a), no
further adjustment of the Exercise Price or number of Warrant Shares shall be made by reason of such issue or sale. 
  

 - 7 - 

 (iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any
Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of
Common Stock increases or decreases at any time, the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be adjusted to the Exercise Price and the number of Warrant Shares which would have been in
effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or
sold. For purposes of this Section 2(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding
sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant
to this Section 2(a) shall be made if such adjustment would result in an increase of the Exercise Price then in effect or a decrease in the number of Warrant Shares. 
 (iv) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no
specific consideration is allocated to such Options by the parties thereto, (x) the Options will be deemed to have been issued for a value determined by use of the Black Scholes Option Pricing Model (the “Option Value”) and
(y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued for the difference of (I) the aggregate consideration received by the Company, less (II) the Option Value. If any shares of Common
Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock,
Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of publicly
traded securities, in which case the amount of consideration received by the Company will be the Weighted Average Price of such security on the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the
owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be 

  

 - 8 - 

 
deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock,
Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Company and the Required Holders. If such parties are unable to reach
agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Business Days after the tenth
(10th) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Required Holders. The
determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company. 
 (v) Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the
date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the
case may be.] 
 (b) Adjustment upon Subdivision or Combination of Common Stock. If the Company at any time on
or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise)
one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be
proportionately decreased. Any adjustment under this Section 2(b) shall become effective at the close of business on the date the subdivision or combination becomes effective. 
 (c) Other Events. If any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided
for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in
the Exercise Price and the number of Warrant Shares so as to protect the rights of the Holder; provided that no such adjustment pursuant to this Section 2(c) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise
determined pursuant to this Section 2. 
  

 - 9 - 

 (d) Voluntary Adjustment By Company. The Company may at any time during the term
of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 
 3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of
return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar
transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case: 
 (a) any Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close
of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which (i) the numerator shall be the Weighted Average Price of the shares of Common Stock on the Trading Day immediately preceding such
record date minus the value of the Distribution (as determined in good faith by the Company’s Board of Directors) applicable to one share of Common Stock, and (ii) the denominator shall be the Weighted Average Price of the shares of
Common Stock on the Trading Day immediately preceding such record date; and 
 (b) in the event that the Distribution is of
shares of Common Stock (or common stock) (“Other Shares of Common Stock”) of a company whose common shares are traded on a national securities exchange or a national automated quotation system, then the Holder may elect to receive a
warrant to purchase Other Shares of Common Stock, the terms of which shall be identical to those of this Warrant, except that such warrant shall be exercisable into the number of shares of Other Shares of Common Stock that would have been payable to
the Holder pursuant to the Distribution had the Holder exercised this Warrant immediately prior to such record date and with an aggregate exercise price equal to the product of the amount by which the exercise price of this Warrant was decreased
with respect to the Distribution pursuant to the terms of the immediately preceding paragraph (a) and the number of Warrant Shares calculated in accordance with the first part of this paragraph (b). 
 4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 
 (a) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock,
warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights,
the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on the exercise of this Warrant)
immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant,
issue or sale of such Purchase Rights. 
  

 - 10 - 

 (b) Fundamental Transactions. The Company shall not enter into or be party to a
Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section (4)(b) pursuant to written
agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders, including agreements to deliver to each holder of the SPA Warrants in exchange for such Warrants a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, an adjusted exercise price equal to the value for the shares of Common Stock reflected by the terms of such
Fundamental Transaction, and exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of
this Warrant) prior to such Fundamental Transaction, and reasonably satisfactory to the Required Holders. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the
date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of
the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction
pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to
insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock (or other
securities, cash, assets or other property) issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or
subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Warrant been exercised immediately prior to such Fundamental Transaction. Provision made pursuant to the preceding
sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied without
regard to any limitations on the exercise of this Warrant. 
 (c)
Notwithstanding the foregoing and the provisions of Section 4(b) above, in the event of a Change of Control, at the request of the Holder delivered before the ninetieth (90th) day after the consummation of such Change of Control, the Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five (5) Business Days after such
request (or, if later, on the effective date of the Change of Control), cash in an amount equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of such Change of Control.

 5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by
amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid
the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the
generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be
necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant and (iii) shall, so long as any of the SPA Warrants are outstanding, take all
action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the SPA Warrants, the number of shares of Common Stock as shall from time to time be
necessary to effect the exercise of the SPA Warrants then outstanding (without regard to any limitations on exercise. 
 6. WARRANT HOLDER
NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share
capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a shareholder of the

Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an
independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at

 - 14 - 

 
of the Holder right to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of
this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it
would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change,
the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of
the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid
provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

 Number of Shares of Common
Stock:              
 Date of Issuance: December     , 2008
(“Issuance Date”) 
 Stereotaxis, Inc., a Delaware corporation (the “Company”), hereby certifies that, for good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [Sanderling Venture Partners VI Co-Investment Fund, L.P.] [Sanderling VI Limited Partnership] [Sanderling VI Beteiligungs GMBH & Co. KG ] [Sanderling
Ventures Management VI][Alafi Capital Company, LLC], the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as
defined below) then in effect, upon surrender of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”), at any time or times on or
after the date immediately after the six month anniversary of the Issuance Date (the “Initial Exercisability Date”) but not after 11:59 p.m., New York time, on the Expiration Date (as defined below),
[            ] ([            ])1 fully paid nonassessable shares of Common Stock (as defined below) (the “Warrant Shares”). This Warrant is one of the Warrants to purchase Common Stock (the “SPA Warrants”) issued pursuant to
Section 1 of that certain Securities Purchase Agreement, dated as of December 29, 2008 (the “Subscription Date”), by and among the Company and the investors (individually, a “Buyer” and collectively, the
“Buyers”) referred to therein (the “Securities Purchase Agreement”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 16. 
 1. EXERCISE OF WARRANT. 
 (a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder at any time or times on or after the
Initial Exercisability Date, in whole or in part, by (i) delivery of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant and
(ii) (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash or by wire
transfer of immediately available funds or (B) by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the original Warrant in
order to effect an exercise hereunder, but shall deliver the original 
  

	1	Insert a number of shares equal to such Holder’s pro rata share of approximately 4,859,504 Common Shares. 

 Warrant within five (5) Business Days after
exercising the Warrant in full. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right
to purchase the remaining number of Warrant Shares. On or before the first (1st) Business Day following the date on which the Company has
received each of the Exercise Notice and the Aggregate Exercise Price (or notice of a Cashless Exercise) (the “Exercise Delivery Documents”), the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of
the Exercise Delivery Documents to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the third (3rd) Trading Day following the date on which the Company has received all of the Exercise Delivery Documents (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in The
Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the
Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch by
overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise. Upon delivery of the Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised,
irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted in connection with any exercise
pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in
no event later than three (3) Business Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such
exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock
to be issued shall be rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. 
 (b) Exercise Price. For purposes of this Warrant, “Exercise Price” means $4.64, subject to adjustment as provided
herein. 
 (c) Company’s Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no
reason to issue to the Holder within three (3) Trading Days of receipt of the Exercise Delivery Documents, a certificate for the number of shares of Common Stock to which the Holder is entitled and register such shares of Common Stock on the
Company’s share register or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the Company’s obligation
pursuant to clause 

  

 - 2 - 

 
(ii) below, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the
Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including actual brokerage commissions, if any) for the shares of Common Stock so
purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Warrant Shares or credit such Holder’s balance account with DTC) shall terminate, or (ii) promptly
honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares or credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In
Price over the product of (A) such number of shares of Common Stock, times (B) the Weighted Average Price on the date of exercise. 
 (d) Cashless Exercise. The Holder may, in its sole discretion (and, notwithstanding anything contained herein to the contrary, if the Registration Statement (as defined in the Securities Purchase Agreement)
covering the issuance of the Warrant Shares that are the subject of the Exercise Notice by the Holder pursuant to the 1933 Act (the “Unavailable Warrant Shares”) is not available for the issuance of such Unavailable Warrant Shares,
the Holder may only) exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such
exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 
  

							
		 	Net Number =	 	 (A x B) - (A x C)
	  	
		 		 	B	  	
		
		 	For purposes of the foregoing formula:
		
	A=	 	the total number of shares with respect to which this Warrant is then being exercised.
		
	B=	 	the Weighted Average Price of the shares of Common Stock (as reported by Bloomberg) on the date immediately preceding the date of the Exercise Notice.
		
	C=	 	the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

 (e) Disputes. In the case of a dispute as to the determination of the
Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 12. 
  

 - 3 - 

 (f) Limitations on Exercises. 
 (i) Principal Market Regulation. The Company shall not be obligated to issue any shares of Common Stock upon exercise of this
Warrant and no Buyer shall be entitled to receive any shares of Common Stock if and to the extent the issuance of such shares of Common Stock would breach the Company’s obligations under the rules or regulations of any applicable Eligible
Market, except that such limitation shall not apply in the event that the Company (A) obtains the approval of its shareholders as required by the applicable rules of the Eligible Market for issuances of shares of Common Stock or
(B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Required Holders. 
 (g) Insufficient Authorized Shares. If at any time while this Warrant remain outstanding the Company does not have a sufficient
number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common Stock equal to (the “Required Reserve Amount”) the
number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of this Warrant then outstanding (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to
increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for this Warrant then outstanding. Without limiting the generality of the foregoing sentence, as soon
as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the
approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval
of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. 
 2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as follows: 
 (a) Adjustment upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date
subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its
outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any
adjustment under this Section 2(a) shall become effective at the close of business on the date the subdivision or combination becomes effective. 
  

 - 4 - 

 (b) Other Events. If any event occurs of the type contemplated by the provisions
of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of
Directors will make an appropriate adjustment in the Exercise Price and the number of Warrant Shares so as to protect the rights of the Holder; provided that no such adjustment pursuant to this Section 2(b) will increase the Exercise Price or
decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2. 
 (c) Voluntary Adjustment
By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 
 3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire
its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case: 
 (a) any Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of
shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which (i) the numerator shall be
the Weighted Average Price of the shares of Common Stock on the Trading Day immediately preceding such record date minus the value of the Distribution (as determined in good faith by the Company’s Board of Directors) applicable to one share of
Common Stock, and (ii) the denominator shall be the Weighted Average Price of the shares of Common Stock on the Trading Day immediately preceding such record date; and 
 (b) in the event that the Distribution is of shares of Common Stock (or common stock) (“Other Shares of Common Stock”) of
a company whose common shares are traded on a national securities exchange or a national automated quotation system, then the Holder may elect to receive a warrant to purchase Other Shares of Common Stock, the terms of which shall be identical to
those of this Warrant, except that such warrant shall be exercisable into the number of shares of Other Shares of Common Stock that would have been payable to the Holder pursuant to the Distribution had the Holder exercised this Warrant immediately
prior to such record date and with an aggregate exercise price equal to the product of the amount by which the exercise price of this Warrant was decreased with respect to the Distribution pursuant to the terms of the immediately preceding paragraph
(a) and the number of Warrant Shares calculated in accordance with the first part of this paragraph (b). 
  

 - 5 - 

 4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 
 (a) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or
sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be
entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant
(without regard to any limitations on the exercise of this Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights. 
 (b)
Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in
accordance with the provisions of this Section (4)(b) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders, including agreements to deliver to each holder of
the SPA Warrants in exchange for such Warrants a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, an adjusted exercise price equal to the
value for the shares of Common Stock reflected by the terms of such Fundamental Transaction, and exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of
this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and satisfactory to the Required Holders. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed
to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of
the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. In addition to and not in substitution for any other rights hereunder, prior
to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate
Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the Fundamental Transaction but prior to the
Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any
other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Warrant been exercised immediately prior to such
Fundamental Transaction. Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions 

  

 - 6 - 

 
of this Section shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied without regard to any
limitations on the exercise of this Warrant. 
 5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will
not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting
the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may
be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant and (iii) shall, so long as any of the SPA Warrants are outstanding, take
all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the SPA Warrants, the number of shares of Common Stock as shall from time to time be
necessary to effect the exercise of the SPA Warrants then outstanding (without regard to any limitations on exercise. 
 6. WARRANT HOLDER

capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a shareholder of the Company or
any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or
subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as
imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding
this Section 6, the Company shall provide the Holder with copies of the same notices and other information given to the shareholders of the Company generally, contemporaneously with the giving thereof to the shareholders. 
 7. REISSUANCE OF WARRANTS. 
 (a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance
with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being
transferred, a new Warrant (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred. 
  

 - 7 - 

 (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case
of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this
Warrant. 
 (c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the
Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new
Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no Warrants for fractional shares of Common Stock shall be given. 
 (d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such
new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being
issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not
exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions
as this Warrant. 
 8. NOTICES. Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such
notice shall be given in accordance with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable detail a
description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) immediately upon any adjustment of the Exercise Price, setting forth in reasonable
detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares
of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock or (C) for determining
rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder.

 9. AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may
take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the 

  

 - 8 - 

 
Company has obtained the written consent of the Required Holders; provided that no such action may increase the exercise price of any SPA Warrant or decrease
the number of shares or class of stock obtainable upon exercise of any SPA Warrant without the written consent of the Holder. No such amendment shall be effective to the extent that it applies to less than all of the holders of the SPA Warrants then
outstanding. 
 10. GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions
concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the
State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. 
  

 - 9 - 

 11. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and
all the Buyers and shall not be construed against any person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. 
 12. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder
and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the
Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed
arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and
notify the Company and the Holder of the results no later than ten Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may
be, shall be binding upon all parties absent demonstrable error. 
 13. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF.
The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive
relief), and nothing herein shall limit the right of the Holder right to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will
cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition
to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 
 14. NO OBLIGATION TO NET CASH SETTLE. Notwithstanding anything to the contrary contained in this Warrant, if the Company is unable to deliver any
securities pursuant to the exercise of this Warrant because a registration statement under the Securities Act of 1933, as amended, with respect to the securities to be issued upon such exercise is not effective or otherwise, the Company will have no
obligation to pay such registered holder any cash or otherwise “net cash settle” the Warrant. 
 15. TRANSFER. This Warrant
may be offered for sale, sold, transferred or assigned without the consent of the Company, except as may otherwise be required by Section 2(f) of the Securities Purchase Agreement. 
 16. SEVERABILITY. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of
competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be 

  

 - 10 - 

 
deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not
affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature,
invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the
parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or
unenforceable provision(s).
