 WARRANT TO PURCHASE
COMMON STOCK 
 Warrant No.:              

Date of Issuance:                     , 2014
(“Issuance Date”) 
 Real Goods Solar, Inc., a Colorado 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 exercise 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 that is six months from the Issuance Date (the “Initial Exercisability Date”),
but not after 11:59 p.m., New York time, on the Expiration Date (as defined below),                      (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 15.
Capitalized terms used and not otherwise defined herein that are defined in the Securities Purchase Agreement (as defined below) will have the respective meanings given such terms in the Securities Purchase Agreement. This Warrant is one of the
Warrants to Purchase Common Stock (the “SPA Warrants”) issued pursuant to that certain Securities Purchase Agreement, dated as of July 2, 2014, by and among the Company and the investors (the “Buyers”) referred
to therein, as amended from time to time (the “Securities Purchase Agreement”). 








	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 on any day on or after the Initial Exercisability Date, in whole or in part, by delivery (whether via facsimile or
otherwise) of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), 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 Company 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 (the
“Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds unless the Holder notifies the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined in
Section 1(d)) to the extent permitted by 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 and issuance of a new Warrant 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 after delivery of the Warrant Shares in accordance with the terms hereof. On or before the first (1st) Trading Day following the date on which the Company has received an Exercise Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of such Exercise
Notice, in the form attached hereto as Exhibit B, to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the later of (i) the third (3rd) Trading Day following the date on which the Company has received such Exercise Notice (or second (2nd) Trading Day if required by a
change to Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, or other rule relating to settlement cycle), and (ii) the second (2nd) Trading Day following the date on which
the Company has received the Aggregate Exercise Price, 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 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 the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, 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 delivery of an Exercise Notice, 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, at the request of the Holder, the Company shall as soon as practicable and in no event later than three (3) Business Days after any exercise 

  
 2 








 
and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 6(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. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issuance and delivery of Common Stock in any name other than that of the Holder of this Warrant.
Notwithstanding the foregoing, except in the case where an exercise of this Warrant is validly made pursuant to a Cashless Exercise (as defined in Section 1(d)), the Company’s failure to deliver Warrant Shares to the Holder on or prior to
the second (2nd) Trading Day after the Company’s receipt of the Aggregate Exercise Price shall not be deemed to be a breach of this Warrant. Notwithstanding any provision of this Warrant to the contrary, no more than the number of Warrant
Shares eligible to be issued pursuant to the limitation in Section 1(f) below shall be exercisable hereunder. 
 (b) Exercise
Price. For purposes of this Warrant, “Exercise Price” means $3.19, 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 the later of (i) three (3) Trading Days after receipt of the applicable Exercise Notice
and (ii) two (2) Trading Days after the Company’s receipt of the Aggregate Exercise Price (or valid notice of a Cashless Exercise) (such later date, the “Share Delivery Deadline”), 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, and if on or after such Share Delivery Deadline 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 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 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 hereunder (as the case may be) and pay cash to the Holder in 

  
 3 








 
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 and ending on the date of such issuance and payment under this clause (ii). 

(d) Cashless Exercise. Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), if at any time
of exercise hereof a Registration Statement (as defined in the Registration Rights Agreement) is not effective (or the prospectus contained therein is not available for use on a continuous basis) for the resale by the Holder of the Warrant Shares
then being exercised at market prices from time to time, then the Holder may, in its sole discretion, 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)  

                        
D 
 For purposes of the foregoing formula: 

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

B=the quotient of (x) the sum of the VWAP of the Common Stock of each of the five (5) Trading Days ending at the close of business on
the Principal Market immediately prior to the time of exercise as set forth in the applicable Exercise Notice, divided by (y) five (5). 

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

D= as applicable: (i) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the date of the applicable
Exercise Notice if such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 1(a) hereof on a Trading Day
prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) the Bid Price of the Common Stock as of the time of the
Holder’s execution of the applicable Exercise Notice if such Exercise Notice is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter pursuant to Section 1(a) hereof, or
(iii) the Closing Sale Price of the Common Stock on the date of the applicable Exercise Notice if the date of such Exercise Notice is a Trading Day and such Exercise Notice is both executed and delivered pursuant to Section 1(a) hereof
after the close of “regular trading hours” on such Trading Day. 

  
 4 








 (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, 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) Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the Holder
hereof, to the extent (but only to the extent) that after giving effect to such exercise the Holder (together with 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 (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 convertible, exercisable or exchangeable (as the case may be, 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 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. 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 “Exchange 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 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 of convertible or exercisable securities into
Common Stock, including, without limitation, pursuant to this Warrant or securities issued pursuant to the Securities Purchase Agreement. At any time the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of
9.99% as specified in a written notice by the Holder to the Company (subject to the Company’s consent to any such increase, not to be unreasonably withheld); provided that (i) any such increase will not be effective until the 61st day
after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder of SPA Warrants. 

  
 5 








 (ii) Principal Market Regulation. The Company shall not issue any shares
of Common Stock upon the exercise of this Warrant if the issuance of such shares of Common Stock (taken together with the Shares and the issuance of such shares of Common Stock upon exercise of the SPA Warrants) would exceed the aggregate number of
shares of Common Stock which the Company may issue upon exercise of the SPA Warrants without breaching the Company’s obligations under the rules or regulations of the Principal Market (the number of shares which may be issued without violating
such rules and regulations, 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 Principal 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 Holder. Until such
approval or such written opinion is obtained, no Buyer shall be issued in the aggregate, upon exercise of the Warrants, shares of Common Stock in an amount greater than the product of (i) the Exchange Cap as of the Issuance Date multiplied by
(ii) the quotient of (1) the number of Shares issued to such Buyer pursuant to the Securities Purchase Agreement on the Closing Date (as defined in the Securities Purchase Agreement) divided by (2) the aggregate number of Shares
issued to all Investors pursuant to the Securities Purchase Agreement on the Closing 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 with respect to such portion of such SPA Warrants so transferred, and the restrictions of the prior sentence shall apply to
such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee. Upon exercise in full of a holder’s SPA Warrants, the difference (if any) between such holder’s Exchange Cap Allocation and
the number of shares of Common Stock actually issued to such holder upon such holder’s exercise in full of such SPA Warrants 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 Common Stock underlying the SPA Warrants then held by each such holder of SPA Warrants. In the event that the Company is prohibited from issuing any shares of Common Stock pursuant to this Section 1(f)(ii)
(the “Exchange Cap Shares”), in lieu of issuing and delivering such Exchange Cap Shares to the Holder, the Company shall pay cash to the Holder in exchange for the cancellation of such portion of this Warrant exercisable into such
Exchange Cap Shares at a price equal to the sum of (x) the product of (A) such number of Exchange Cap Shares and (B) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date the
Holder delivers the applicable Exercise Notice with respect to such Exchange Cap Shares to the Company and ending on the date of such payment under this Section 1(f)(ii) and (y) to the extent 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 Exchange Cap Shares, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith.

 (g) Insufficient Authorized Shares. The Company shall at all times keep reserved for
issuance under this Warrant a number of shares of Common Stock at least equal to 135% of the maximum 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 of this Warrant). If, notwithstanding the foregoing, and not in limitation thereof, at any time while any
of the SPA 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 of the SPA Warrants at least a number of shares
of Common Stock (the “Required Reserve Amount”) equal to the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of the SPA Warrants then outstanding (an “Authorized Share
Failure”), then the Company shall promptly take all action reasonably 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
SPA 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 sixty (60) 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 reasonable best 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. In the event that the Company is prohibited from issuing shares of Common Stock upon an exercise of this Warrant due to the failure by the Company to have sufficient shares of Common Stock available out of the authorized but unissued
shares of Common Stock (such unavailable number of shares of Common Stock, the “Authorization Failure Shares”), in lieu of delivering such Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the
cancellation of such portion of this Warrant exercisable into such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorization Failure Shares and (y) the greatest Closing Sale Price of
the Common Stock on any Trading Day during the period commencing on the date the Holder delivers the applicable Exercise Notice with respect to such Authorization Failure Shares to the Company and ending on the date of such issuance and payment
under this Section 1(g) and (ii) to the extent 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 Authorization Failure Shares, any brokerage
commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. 
 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 2(b), or Section 3, 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


  
 7 








 
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. Simultaneously with any adjustment to the Exercise Price pursuant to this paragraph, 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). 
 (b) Other Events.
In the event that the Company (or any Subsidiary) shall take any 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(b) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined
pursuant to this Section 2. 
 (c) Calculations. All calculations under this Section 2 shall be made by rounding to the
nearest cent or 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. 
 3. 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 the 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). 

  
 8 








 (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 3(b) pursuant to written
agreements in form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements 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). Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted
for (so that from and after the date of the applicable Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents 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 and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein. Upon
consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after consummation of the applicable Fundamental Transaction, in lieu of
the share of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Section 3(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 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), as adjusted in accordance with the provisions of this Warrant. Notwithstanding the foregoing, and without
limiting Section 1(f) hereof, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 3(b) to permit the Fundamental Transaction without the assumption of this Warrant. 

(c) Black Scholes Value. 

(i) Fundamental Transaction Redemption by the Holder. Notwithstanding the provisions of Section 3(b) above, at the
request of the Holder delivered at any time commencing on the earliest to occur of (x) the public disclosure of any “person” or “group” (as these terms are used for purposes of Sections 13(d) and 14(d) of the Exchange
Act and the rules and regulations promulgated thereunder) becoming the 

  
 9 








 
“beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% of the aggregate ordinary voting power represented by issued and outstanding Voting
Stock of the Company (a “Change of Control”), (y) the consummation of any Change of Control and (z) the Holder first becoming aware of any Change of Control, through the date that is twenty (20) days after the public
disclosure of the consummation of such Change of Control by the Company pursuant to a Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”), the Company or the Successor Entity (as the case may be)
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. 

(ii) Going Private Redemption by the Company. Notwithstanding the foregoing and the provisions of Section 3(b)
above, at any time after the date of the public disclosure of a Fundamental Transaction in which neither the Successor Entity nor its Parent Entity in such Fundamental Transaction is a publicly traded corporation with common equity that is quoted on
or listed for trading on an Eligible Market (a “Going Private Transaction”), the Company may, at its option, redeem this Warrant in full, not in part, from the Holder on the date of consummation of such Going Private Transaction
(the “Going Private Date”) by paying to the Holder cash in an amount equal to the Going Private Black Scholes Value (the “Going Private Redemption Amount”, and such redemption, a “Going Private
Redemption”). The Company may exercise its right to require redemption under this Section 3(c)(ii) by delivering an irrevocable written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of
SPA Warrants (the “Going Private Redemption Notice” and the date all of the holders of SPA Warrants received such notice is referred to as the “Going Private Redemption Notice Date”). The Company may deliver only
one Going Private Redemption Notice in any sixty (60) day period. The Going Private Redemption Notice shall (x) state the date on which the Going Private Redemption shall occur (the “Going Private Redemption Date”) which
date shall not be less than thirty (30) calendar days nor more than sixty (60) calendar days following the Going Private Redemption Notice Date and (y) state the Going Private Redemption Amount (with back-up calculations) which is
being redeemed in such Going Private Redemption from the Holder and all of the other holders of the SPA Warrants pursuant to this Section 3(c)(ii) (and analogous provisions under the other SPA Warrants) on the Going Private Redemption Date.
Until the Going Private Redemption Amount is paid in full, this Warrant may be exercised, in whole or in part, by the Holder into Common Stock pursuant to Section 1. In the event the Holder elects to exercise any portion of this Warrant after
the Going Private Redemption Notice Date, the Going Private Black Scholes Value of the portion so exercised shall be deducted from the Going Private Redemption Amount the Company shall pay to the Holder on the Going Private Date. 

(d) Application. The provisions of this Section 3 shall apply similarly and equally to successive Fundamental Transactions and
shall be applied as if this Warrant (and any such subsequent warrants) 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 Exchange Act and thereafter receivable upon exercise of this Warrant (or any such other warrant)).

 4. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of
its articles 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

effective unless it is in writing and signed by an authorized representative of the waiving party. 
 9. 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 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). 
 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. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, 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. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing
contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder or to enforce a judgment or
other court ruling in favor of the Holder. 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 CONTEMPLATED HEREBY.

 11. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the
Holder 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, the Closing Sale Price, the Bid Price or fair market
value or the arithmetic calculation of the number of Warrant Shares (as the case may be), the Company or the Holder (as the case may be) shall submit the disputed determinations or arithmetic calculations (as the case may be) via facsimile
(i) within two (2) Business Days after receipt of the applicable notice giving rise to such dispute to the Company or the Holder (as the case may be) or (ii) if no notice gave rise to such dispute, at any time after the Holder learned
of the circumstances giving rise to such dispute. If the Holder and the Company are unable to agree upon such determination or calculation (as the case may be) of the Exercise Price, the Closing Sale Price, the Bid Price or fair market value or the
number of Warrant Shares (as the case may be) within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to the Company or the Holder (as the case may be), then the Company shall, within two
(2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price, the Closing Sale Price, the Bid Price or fair market value (as the case may be) to an independent, reputable investment bank selected by the
Company and reasonably acceptable to the Holder or (b) the disputed arithmetic calculation of the number of Warrant Shares to the Company’s independent, outside accountant. The Company shall cause the investment bank or the accountant (as
the case may be) to perform the determinations or calculations (as the case may be) and notify the Company and the Holder of the results no later than ten (10) Business Days from the time it receives such disputed determinations or calculations
(as the case may be). Such investment bank’s or accountant’s determination or calculation (as the case may be) shall be binding upon all parties absent manifest error. The loser of the dispute shall pay the fees and out of pocket expenses
of such investment bank or accountant. 
 13. REMEDIES, CHARACTERIZATION, 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 to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company covenants to the Holder that there shall be no characterization concerning this instrument other
than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, exercises and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided
herein, be subject to any other obligation of the Company (or the performance thereof). 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. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the
Company’s compliance with the terms and conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates for shares as contemplated hereby upon the exercise of this
Warrant shall be made

without charge to the Holder or such shares for any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.
