[    ], 2015 (“Issuance Date”) 
 Great Basin Scientific, Inc., a Delaware corporation (the

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 exercise of this Series C 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 Issuance Date, but not after 11:59 p.m., New York
time, on the Expiration Date (as defined below), [5 YEARS FROM DATE OF THE PROSPECTUS] (subject to adjustment as provided herein) fully paid and non-assessable shares of Common Stock (as defined below) (the “Warrant Shares”).
Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 16. This Warrant is one of the Warrants to Purchase Common Stock (the “Purchased Warrants”) issued pursuant to
the Offering (as defined in that certain Underwriting Agreement, dated as of February 25, 2015, by and between the Company and Dawson James Securities, Inc., as representative of the several underwriters, as amended by that certain amendment
dated February 27, 2015 (the “Underwriting Agreement”)). 
 This Warrant shall be issuable in book entry
form (the “Book-Entry Warrant Certificate”) and shall initially be represented by one or more Book-Entry Warrant Certificates deposited with American Stock Transfer and Trust Company (the “Warrant Agent”) and
registered in the name of the Holder, or as otherwise directed by the Warrant Agent. Ownership of beneficial interests in this Warrant shall be shown on, and the transfer of such ownership shall be effected through, records maintained by the Warrant
Agent (the “Warrant Register”). The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes,
absent actual written notice to the contrary. 
 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, in whole or in part, at the Holder’s election (x) upon the earlier of (i) any day on or after the date that is six months after February 25, 2015, or (ii) any
day on or after the fifteenth (15th) day after the Early Exercise Trigger Date, or (y) at any time upon the delivery of the Exercise Price in cash. The Holder shall exercise this
Warrant, in each case, by delivery (whether via e-mail, facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit A (the 







 
“Exercise Notice”) to the Warrant Agent or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the
Holder appearing on the books of the Company or the Warrant Agent (or to the Company if the exercise is made pursuant to a Cashless Exercise (as defined in Section 1(d)), of the Holder’s election to exercise this Warrant. Within one
(1) Trading Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Warrant Agent of an amount equal to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares
as to which this Warrant was so exercised (in respect of such specific exercise, the “Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds (to the account set forth on Schedule A
hereto) if the Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the original of this Warrant in order
to effect an exercise hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original of this Warrant certificate and issuance of a new Warrant
certificate evidencing the right to purchase the remaining number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have the same effect as cancellation of the original of this Warrant
certificate after delivery of the Warrant Shares in accordance with the terms hereof. The Holder and the Company or the Warrant Agent shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company
or the Warrant Agent shall deliver any objection to any Notice of Exercise form within 2 Business Days of receipt of the applicable Notice of Exercise. On or before the first (1st) Trading Day following the date on which the Company has
received an Exercise Notice for a Cashless Exercise, the Company shall transmit by e-mail or facsimile an acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto as Exhibit B, to the Warrant
Agent. On or before the third (3rd) Trading Day following (A) in the event of a Cashless Exercise, the date on which the Company has received such Exercise Notice or (B) in the event of an exercise for cash, the later of (i) the
date on which the Warrant Agent has received such Exercise Notice or (ii) the date on which the Warrant Agent receives the Aggregate Exercise Price (such date is referred to herein as the “Delivery Date”), the Company shall,
(X) provided that (I) the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program and (II) either a registration statement for the issuance to the Holder of
the applicable Warrant Shares to be issued pursuant to such Exercise Notice is effective and the prospectus contained therein is usable or such Warrant Shares to be so issued are otherwise freely tradable, cause the Warrant Agent to credit such
aggregate number of shares of Common Stock 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 at Custodian system, or (Y) if either of
the immediately preceding clauses (I) or (II) are not satisfied, issue and deliver to the Holder or, at the Holder’s instruction pursuant to the Exercise Notice, the Holder’s agent or designee, in each case, sent by reputable
overnight courier to the address as specified in the applicable Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee (as indicated in the applicable Exercise Notice), for the
number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon (A) in the event of a Cashless Exercise, the date on which the Company has received such Exercise Notice or (B) in the event of an exercise
for cash, the later of (i) the date on which the Warrant Agent has received such Exercise Notice or (ii) the date on which the Warrant Agent receives the 







 
Aggregate Exercise Price, 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); provided, however, that if the date of such receipt is a date
upon which the Common Stock transfer books of the Company are closed, such Holder shall be deemed to have become the record holder of such shares on, the next succeeding day on which the Common Stock transfer books of the Company are open. 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, at the request of the Holder and upon surrender hereof by the Holder at the principal office of the Company, 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 and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares purchasable 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 and fees 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 $2.55, 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 on or before the applicable Delivery Date, 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 to credit the Holder’s
balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the case may be), then, in addition to all other remedies available to the Holder, the Company
shall pay in cash to the Holder on each day after such third (3rd) Trading Day that the issuance of such shares of Common Stock is not timely effected an amount equal to 2% of the product of (A) the aggregate number of shares of Common
Stock not issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the last possible date on which the Company could have issued such
shares of Common Stock to the Holder without violating Section 1(a). In addition to the foregoing, if the Company shall fail to issue and deliver a certificate to the Holder 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 or exchange hereunder (as the case may be) on or prior to the applicable Delivery
Date, and if on or after such Delivery Date the Holder (or any other Person in respect, or on behalf, of 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
all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, issuable upon such exercise or exchange that the Holder so anticipated
receiving from the Company, then, in addition to all other remedies available to the Holder, 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 brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of the Holder) (the
“Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate 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 or exchange hereunder (as the case may be) (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates
representing such shares of Common Stock 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 or exchange hereunder (as the case may be) 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 multiplied by (B) the lowest Closing Sale Price of the Common Stock on any Trading Day during
the period commencing on the date of the applicable Exercise Notice or Exchange Notice, as the case may be, and ending on the date of such issuance and payment under this clause (ii). 

(d) Cashless Exercise. Solely to the extent of an exercise permitted by Section 1(a)(x) and subject to Section 1(f) below, the
Holder may, in its sole discretion (and without limiting the Holder’s rights and remedies contained herein), exercise this Warrant in whole or in part and, subject to the provisions of Section 1(a), 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 a cash payment from the Company equal to the product of (i) the total number of shares
with respect to which this Warrant is then being exercised multiplied by (ii) the Black Scholes Value (as defined below) (the “Exchange Amount”). In the Company’s sole discretion, so long as the Equity Conditions has
occurred the Company may elect to treat such notice as a cashless exercise of the Warrant with respect to the number of shares specified in “A” below for the “Net Number” of shares of Common Stock determined according to the
following formula with respect thereto (a “Cashless Exercise”), as follows: 
 Net Number = (A x B) / C 

For purposes of the foregoing formula: 

A= the total number of shares with respect to which this Warrant is then being exercised. 

B= Black Scholes Value (as defined below). 

C= the Closing Bid Price of the Common Stock as of two (2) Trading Days prior to the time of such exercise (as defined below). 

(e) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant
Shares to be issued pursuant to the terms hereof (including, without limitation, the Net Number), the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed, provided that following such issuance to Holder such
dispute shall be resolved in accordance with Section 13. 







 (f) Limitations on Exercises and Exchanges. Notwithstanding anything to the contrary contained in
this Warrant, this Warrant shall not be exercisable or exchangeable by the Holder hereof to the extent (but only to the extent) that the Holder or any of its Affiliates would beneficially own in excess of 4.99% (the “Maximum
Percentage”) of the Common Stock. To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable or exchangeable (vis-à-vis other convertible, exercisable or exchangeable securities owned
by the Holder or any of its Affiliates) and of which such securities shall be exercisable or exchangeable (as among all such securities owned by the Holder) shall, subject to such Maximum Percentage limitation, be determined on the basis of the
first submission to the Company for conversion, exercise or exchange (as the case may be). No prior inability to exercise or exchange this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this
paragraph with respect to any subsequent determination of exercisability or exchangeability. For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with respect to
calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and the rules and regulations promulgated thereunder. The
provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum
Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a
successor Holder of this Warrant. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not amend or waive this paragraph without the consent of holders of a majority of its Common Stock. 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, including by virtue of any prior
conversion or exercise or exchange of convertible or exercisable or exchangeable securities into Common Stock, including, without limitation, pursuant to this Warrant or securities issued pursuant to the Certificate of Designation for the Series E
Convertible Preferred Stock. 
 (g) Insufficient Authorized Shares. 

The Company shall at all times keep reserved for issuance under this Warrant a number of shares of Common Stock as shall be necessary to
satisfy the Company’s obligation to issue shares of Common Stock hereunder (without regard to any limitation otherwise contained herein with respect to the number of shares of Common Stock that may be acquirable upon exercise or exchange of
this Warrant). If, notwithstanding the foregoing, and not in limitation thereof, at any time while any of the Purchased Warrants 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 or exchange of the Purchased Warrants at least a number of shares of Common Stock equal to the number of shares of Common Stock as shall from time to time be necessary to effect the
exercise or exchange of all of the Purchased Warrants then outstanding (the “Required Reserve Amount”) (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 all the Purchased Warrants 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 ninety
(90) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its shareholders 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 shareholder with a proxy statement and shall use its commercially reasonable efforts to solicit its shareholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to
recommend to the shareholders that they approve such proposal. 
 2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and
number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2. 

(a) Stock Dividends and Splits. Without limiting any provision of Section 4, if the Company, at any time on or after the Issuance Date,
(i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split,
stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its
then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before
such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record
date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such
subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect
such event. 
 (b) [RESERVED]. 

(c) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this Section 2,
the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares
shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein). In addition, and notwithstanding anything to the contrary contained herein,
(x) upon a Cashless Exercise as set forth in Section 1(d) hereof, the number of Warrant Shares for which this Warrant is exercisable immediately following such Cashless Exercise shall be equal to (i) the number of Warrant Shares for
which this Warrant was exercisable immediately prior to such Cashless Exercise less (ii) the number of Warrant Shares as to which such Cashless Exercise was 







 
exercised (such number of Warrant Shares in this clause (ii) in respect of such Cashless Exercise being equal to “A” in such Cashless Exercise formula in respect of such Cashless
Exercise) and (y) the number of Warrant Shares issuable hereunder shall automatically be increased, as necessary, to enable to the Company to comply with its obligations to issue the Net Number of shares of Common Stock under Section 1(d)
hereof upon any Cashless Exercise hereunder. 
 (d) Calculations. All calculations under this Section 2 shall be made by rounding to
the nearest 1/10000th of cent and the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of
any such shares shall be considered an issue or sale of Common Stock. 
 (e) Other Events. In the event that the Company shall take any
similar action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 2 but not
expressly provided for by such provisions, then the Company’s board of directors shall in good faith determine and implement an appropriate adjustment in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the
rights of the Holder, provided that no such adjustment pursuant to this Section 2(e) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2, provided further that if the
Required Holders (as defined below) do not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Company’s board of directors and the Required Holders shall agree, in good faith, upon an
independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be borne by the Company. 

3. RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if the Company, at any time prior to the three year
anniversary of the Issuance Date, shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to all or substantially all of the 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, indebtedness, 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, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein 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 exercise hereof, including without limitation, the Maximum Percentage) immediately before the date on which
a record is taken for such Distribution, 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 participation in such Distribution (provided, however, to the extent that the
Holder’s right to participate in any such Distributions would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (or the beneficial ownership of any
such shares of Common Stock as a result of such Distribution to such extent) and such Distribution to such extent shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder
exceeding the Maximum Percentage), provided further, 







 
such Distribution shall be held in abeyance for the benefit of the Holder until such time as the Holder exercises this Warrant (whether in whole or in part), and subject to the foregoing proviso,
upon each exercise of this Warrant the Company shall make such Distribution to the Holder with respect to each Warrant Share for which this Warrant is so exercised until such time as this Warrant has been exercised in full). 

4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 

(a) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if the Company, at any time prior to the three year
anniversary of the Issuance Date, grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to all or substantially all of 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 exercise hereof, including without limitation, the Maximum Percentage) 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 (provided, however,
to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or
beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Maximum Percentage), and provided further, that such Purchase Rights shall be held in abeyance for the benefit of the Holder until such time as the Holder exercises this Warrant (whether in whole or in part), and subject to
the foregoing proviso, upon each exercise of this Warrant the Company shall deliver such Purchase Rights to the Holder with respect to each Warrant Share for which this Warrant is so exercised until such time as this Warrant has been exercised in
full). 
 (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 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 prior to such Fundamental Transaction, including agreements confirming the obligations of the Successor Entity as set forth in this paragraph (b) and (c) and elsewhere in this Warrant and an obligation to
deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, which is 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 with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of
such shares of capital stock, such adjustments to the number of 







 
shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction).
Notwithstanding the foregoing, at the election of the Holder upon exercise of this Warrant following a Fundamental Transaction, the Successor Entity shall deliver to the Holder, in lieu of the shares of Common Stock (or other securities, cash,
assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such
shares of common stock (or its equivalent) of the Successor Entity (including its Parent Entity), or other securities, cash, assets or other property, which the Holder would have been entitled to receive upon the happening of the applicable
Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). 

(c) Black Scholes Value—FT. Notwithstanding the foregoing and the provisions of Section 4(b) above, at the request of the Holder
delivered at any time commencing on the date of the consummation of any such Fundamental Transaction through the date that is thirty (30) days after the consummation of any such Fundamental Transaction, the Company or the Successor Entity, at
the election of the Holder, shall purchase this Warrant from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Black Scholes Value—FT. 

(d) Application. The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and shall be
applied as if this Warrant (and any such subsequent warrants issued hereunder) were fully exercisable and without regard to any limitations on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the
Maximum Percentage, applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of this Warrant (or any such other warrant)). 

5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Charter (as defined in the Underwriting
Agreement), Bylaws (as defined in the Underwriting Agreement) 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 non-assessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the Purchased 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 Purchased Warrants, the maximum number of shares of Common Stock
as shall from time to time be necessary to effect the exercise of the Purchased 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 its 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 its capacity as the Holder of this Warrant, any of the rights of a stockholder 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 it 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 stockholder 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 stockholders of the Company
generally, contemporaneously with the giving thereof to the stockholders; provided however, that the Company shall not be obligated to provide such information if it is filed with the SEC through EDGAR and available to the public through the EDGAR
system. 
 7. REISSUANCE OF WARRANTS. 
 (a)
Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant (or the Book Entry Warrant Certificate) to the Company or the Warrant Agent (or other designated agent), whereupon the Company or the Warrant Agent
(or other designated agent) will forthwith issue and deliver upon the order of the Holder a new Warrant (or Book Entry Warrant Certificate) (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 (or Book Entry Warrant Certificate) (in accordance with
Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred. 
 (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 (or the Book Entry Warrant Certificate) (as to which a written certification and the
indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary and reasonable form (including posting a bond) and, in
the case of mutilation, upon surrender and cancellation of this Warrant (or the Book Entry Warrant Certificate), the Company shall execute and deliver to the Holder a new Warrant (or Book Entry Warrant Certificate) (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 (or of the Book Entry Warrant Certificate) by the Holder at the principal office of the Company, for a new Warrant or Warrants (or Book Entry Warrant Certificates) (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 (or Book Entry Warrant Certificate) 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, 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 (or Book Entry Warrant Certificate) pursuant to the

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

action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.

Section 13. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION

serve as the basis for the selected accountant’s or accounting firm’s performance of the applicable arithmetic calculation of the number of Warrant Shares, (iv) for clarification purposes and without implication that the contrary

shall have the right to submit any dispute described in this Section 13 to any state or federal court sitting in The City of New York, Borough of Manhattan in lieu of utilizing the procedures set forth in this Section 13 and
