SERIES
O Warrant To Purchase Common Stock


 


Warrant No.: O-[___]


Number of Shares of Common Stock: [___]


Date of Issuance: [_____ __], 2018 (“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, [PURCHASER], 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 in Section 1(b)) then in effect, at any time or times on or after the Initial
Exercisability Date, but not after 11:59 p.m., New York time, on the Expiration Date, up to such number of fully paid and nonassessable
shares of Common Stock equal to [________], subject to adjustment as provided herein (the “Warrant Shares”).
Except as otherwise defined herein, capitalized terms in this Series O Warrant to Purchase Common Stock (including any warrants
to purchase Common Stock issued in exchange, transfer or replacement hereof, this “Warrant”), shall have the
meanings set forth in Section 17. This Warrant is one of the Series O Warrants to Purchase Common Stock (the “Series O
Warrants”) originally issued pursuant to Section 2 of the Securities Purchase Agreement, dated as of January 2, 2017
(the “Subscription Date”), by and among the Company and the purchasers signatory thereto.


 


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 (as defined in Section 1(b)) multiplied by the number of Warrant Shares as to which this Warrant is being exercised
(the “Aggregate Exercise Price”) in cash by wire transfer of immediately available funds or (B) if the provisions
of Section 1(d) are applicable, 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.
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. No ink-original Exercise Notice shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization)
of any Exercise Notice be required. 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 the Exercise
Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder
and the Company’s transfer agent (the “Transfer Agent”). On or before the earlier of (i) the second (2nd)
Trading Day and (ii) the number of Trading Days comprising the Standard Settlement Period, following the date on which the Company
has received the Exercise Notice, so long as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless Exercise)
on or prior to the first (1st) Trading Day following the date on which the Company has received the Exercise Notice (the “Share
Delivery Date”) (provided that if the Aggregate Exercise Price has not been delivered by such date, the Share Delivery
Date shall be one (1) Trading Day after the Aggregate Exercise Price (or notice of a Cashless Exercise) is delivered), the Company
shall, (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated
Securities Transfer Program and the Holder may sell the Warrant Shares without restriction or limitation either (I) pursuant to
Rule 144 of the 1933 Act (including without the requirement to be in compliance with Rule 144(c)(1) of the 1933 Act) or (II) pursuant
to an effective registration statement registering the Warrant Shares for issuance or resale, credit such aggregate number of Warrant
Shares to which the Holder is entitled pursuant to such exercise to the Holder’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, or if the Holder may not sell the Warrant Shares without restriction or limitation either (I) pursuant to Rule 144 of
the 1933 Act (including having to comply with 144(c)(1) of the 1933 Act) or (II) pursuant to an effective registration statement
registering the Warrant Shares for issuance or resale, 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 for the number of Warrant
Shares to which the Holder is entitled pursuant to such exercise. The Company agrees to maintain a transfer agent that is a participant
in the DTC Fast Automated Securities Transfer Program so long as this Warrant remains outstanding and exercisable. The Company
shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to the issuance of
Warrant Shares via DTC, if any. Upon delivery of the 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 the Company shall as soon as practicable and in no event later than three (3) Trading
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 Warrant Shares are to be issued upon the exercise of this
Warrant, but rather the number of Warrant Shares to be issued shall be rounded up to the nearest whole number. The Company shall
pay any and all taxes (other than the Holder’s income taxes) which may be payable with respect to the issuance and delivery
of Warrant Shares upon exercise of this Warrant. The Company’s obligations to issue and deliver Warrant Shares in accordance
with the terms and subject to the conditions hereof are absolute and unconditional, irrespective of any action or inaction by the
Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any
Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination.


 




     


     


    

 


(b)       Exercise
Price. For purposes of this Warrant, “Exercise Price” means $1.47, 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, in the manner required by
Section 1(a), to issue to the Holder on or prior to the Share Delivery Date if the Transfer Agent is not participating in the DTC
Fast Automated Securities Transfer Program, 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 if the Transfer Agent is participating in the
DTC Fast Automated Securities Transfer Program, 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, and if on or after the Share
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 equal to or any portion of the number of shares of Common Stock issuable upon such exercise that the Holder
anticipated receiving from the Company (a “Buy-In”), then, in addition to all other remedies available to the
Holder, the Company shall, within three (3) Trading 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 (the “Buy-In Price”),
at which point the Company’s obligation to deliver such certificate (and to issue such shares of Common Stock) or credit
such Holder’s balance account with DTC for such shares of Common Stock shall terminate, or (ii) promptly honor its obligation
to deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit such Holder’s balance
account with DTC, as applicable, 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) any trading price of the Common Stock selected by the Holder
in writing as in effect at any time during the period beginning on the date of the applicable Exercise Notice and ending on the
date of such issuance and payment under this Section 1(c). Nothing shall limit the Holder’s right to pursue any other remedies
available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or injunctive
relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock (or to electronically
deliver such shares of Common Stock) upon the exercise of this Warrant as required pursuant to the terms hereof.

(d)       Cashless
Exercise. Notwithstanding anything contained herein to the contrary, if the issuance or resale of the Warrant Shares is not
registered on an effective registration statement under the 1933 Act (the “Registration Statement”), 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
arithmetic average of the Closing Sale Prices of the Common Stock for the five (5) consecutive Trading Days ending 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.


 


D= the
Closing Sale Price of the Common Stock on the date of the Exercise Notice.


 


For purposes of Rule
144(d) under the 1933 Act, as in effect on the date hereof, the Warrant Shares issued in a Cashless Exercise shall be deemed to
have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date
this Series O Warrant was originally issued pursuant to the Securities Purchase Agreement.


 


(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)       Beneficial
Ownership Limitation on Exercises. Notwithstanding anything to the contrary contained herein, the Company shall not
effect the exercise of any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this
Warrant, pursuant to the terms and conditions of this Warrant and any such exercise shall be null and void and treated as if
never made, to the extent that after giving effect to such exercise, the Holder together with the other Attribution Parties
collectively would beneficially own in excess of 9.95% (the “Maximum Percentage”) of the number of 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 the Holder and the other Attribution Parties shall include
the number of shares of Common Stock held by the Holder and all other Attribution Parties plus 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 the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised
portion of this Warrant beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or
conversion of the unexercised or unconverted portion of any other securities of the Company (including, without limitation,
any convertible notes or convertible preferred stock or warrants) beneficially owned by the Holder or any other Attribution
Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 1(f). For
purposes of this Section 1(f), 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 acquire upon the exercise of this Warrant without exceeding
the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the
Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other
public filing with the Securities and Exchange Commission (the “SEC”), as the case may be, (y) a more
recent public announcement by the Company or (3) any other written notice by the Company or the Transfer Agent setting forth
the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). If the Company
receives an Exercise Notice from the Holder at a time when the actual number of outstanding shares of Common Stock is less
than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing of the number of shares of
Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s
beneficial ownership, as determined pursuant to this Section 1(f), to exceed the Maximum Percentage, the Holder must notify
the Company of a reduced number of Warrant Shares to be purchased pursuant to such Exercise Notice (the number of shares by
which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the
Company shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. 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 or by electronic mail 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 this Warrant, by the Holder and any other Attribution Party since the date as of which the Reported
Outstanding Share Number was reported. In the event that the issuance of shares of Common Stock to the Holder upon exercise
of this Warrant results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate,
more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of
the 1934 Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate
beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void
and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As soon
as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the Company shall return to
the Holder the exercise price paid by the Holder for the Excess Shares. Upon delivery of a 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% as
specified in such notice; provided, however, that (i) any such increase in the Maximum Percentage 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 Holder and the other Attribution Parties and not to any other holder of Series O
Warrants that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock issuable
pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the
Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. 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) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or
inconsistent with the intended beneficial ownership limitation contained in this Section 1(f) or to make changes or
supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may
not be waived and shall apply to a successor holder of this Warrant.

(g)       Insufficient
Authorized Shares. If at any time while this Warrant remains 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 maximum 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 (the “Required Reserve Amount” and the failure
to have such sufficient number of authorized and unreserved shares of Common Stock, 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 this Warrant and the other Series
O 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 seventy-five (75) days after the occurrence of such Authorized
Share Failure, the Company shall either (x) obtain the written consent of its shareholders for the approval of an increase in the
number of authorized shares of Common Stock and provide each shareholder with an information statement with respect thereto or
(y) 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. Notwithstanding the foregoing, if any such time of an Authorized
Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding Common
Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation by obtaining
such consent and submitting for filing with the SEC an Information Statement on Schedule 14C. The initial number of shares of Common
Stock reserved for exercise of this Warrant and the other Series O Warrants and each increase in the number of shares so reserved
shall be allocated pro rata among the Holder and the holders of the other Series O Warrants, based on the number of shares of Common
Stock issuable upon exercise of this Warrant (without regard to any limitations in exercise) issued to the Holder on the Issuance
Date (the “Authorized Share Allocation”). In the event that the Holder shall sell or otherwise transfer this
Warrant, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of
Common Stock reserved and allocated to any Person which ceases to hold any Series O Warrants shall be allocated to the Holder and
the remaining holders of Series O Warrants, pro rata based on the shares of Common Stock issuable upon exercise of the Series O
Warrants then held by such holders (without regard to any limitations on the exercise of the Series O Warrants).


 


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)       [RESERVED]


 


(b)       Adjustment
Upon Subdivision or Combination of Shares 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, as mutually determined by the Company’s Board of Directors and the Required Holders, so as
to protect the rights of the Holder; provided, however, 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.


 




    	 	- 5 -	 



     


    

 


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, options, evidence of indebtedness or any other assets 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 or restrictions on exercise of this Warrant,
including without limitation, the Maximum Percentage) immediately before the date of 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, that to the extent that the Holder’s right to participate
in any such Distribution would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the
Holder shall not be entitled to participate in such Distribution to such extent (and shall not be entitled to beneficial ownership
of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to such extent) and the portion of such
Distribution shall be held in abeyance for the benefit of the Holder until such time or times as its right thereto would not result
in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted
such Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly
in abeyance) to the same extent as if there had been no such limitation).


 


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 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
or restrictions on exercise of this Warrant, 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, that to the extent that the Holder’s right to participate in any such Purchase Right would
result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled
to participate in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such shares of Common
Stock as a result of such Purchase Right (and beneficial ownership) to such extent) and such Purchase Right to such extent shall
be held in abeyance for the benefit of the Holder until such time or times as its right thereto would not result in the Holder
and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right
(and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right held similarly
in abeyance) to the same extent as if there had been no such limitation).


 




    	 	- 6 -	 



     


    

 


(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, such approval not to be unreasonably withheld or delayed, prior to such Fundamental Transaction,
including agreements, if so requested by the Holder, to deliver to each holder of the Series O Warrants in exchange for such Series
O 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, 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 occurrence or consummation of such Fundamental Transaction). Upon the occurrence or consummation
of any Fundamental Transaction, and it shall be a required condition to the occurrence or consummation of any Fundamental Transaction
that, the Company and the Successor Entity or Successor Entities, jointly and severally, shall succeed to, and the Company shall
cause any Successor Entity or Successor Entities to jointly and severally succeed to, and be added to the term “Company”
under this Warrant (so that from and after the date of such Fundamental Transaction, and the provisions of this Warrant referring
to the “Company” shall refer instead to each of the Company and the Successor Entity or Successor Entities, jointly
and severally), and the Company and the Successor Entity or Successor Entities, jointly and severally, may exercise every right
and power of the Company prior thereto and shall assume all of the obligations of the Company prior thereto under this Warrant
with the same effect as if the Company and such Successor Entity or Successor Entities, jointly and severally, had been named as
the Company in this Warrant, and, solely at the request of the Holder, if the Successor Entity and/or Successor Entities is a publicly
traded corporation whose common stock is quoted on or listed for trading on an Eligible Market, shall deliver (in addition to and
without limiting any right under this Warrant) to the Holder in exchange for this Warrant a security of the Successor Entity and/or
Successor Entities evidenced by a written instrument substantially similar in form and substance to this Warrant and exercisable
for a corresponding number of shares of capital stock of the Successor Entity and/or Successor Entities (the “Successor
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 (such corresponding number of
shares of Successor Capital Stock to be delivered to the Holder shall be equal to the greater of (A) the quotient of (i) the aggregate
dollar value of all consideration (including cash consideration and any consideration other than cash (“Non-Cash Consideration”),
in such Fundamental Transaction, as such values are set forth in any definitive agreement for the Fundamental Transaction that
has been executed at the time of the first public announcement of the Fundamental Transaction or, if no such value is determinable
from such definitive agreement, as determined in accordance with Section 12 with the term “Non-Cash Consideration”
being substituted for the term “Exercise Price”) that the Holder would have been entitled to receive upon the happening
of such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental
Transaction, had this Warrant been exercised immediately prior to such Fundamental Transaction or the record, eligibility or other
determination date for the event resulting in such Fundamental Transaction (without regard to any limitations on the exercise of
this Warrant) (the “Aggregate Consideration”) divided by (ii) the per share Closing Sale Price of such Successor
Capital Stock on the Trading Day immediately prior to the consummation or occurrence of the Fundamental Transaction and (B) the
product of (i) the Aggregate Consideration and (ii) the highest exchange ratio pursuant to which any shareholder of the Company
may exchange Common Stock for Successor Capital Stock) (provided, however, that to the extent that the Holder’s
right to receive any such shares of publicly traded common stock (or their equivalent) of the Successor Entity would result in
the Holder and its other Attribution Parties exceeding the Maximum Percentage, if applicable, then the Holder shall not be entitled
to receive such shares to such extent (and shall not be entitled to beneficial ownership of such shares of publicly traded common
stock (or their equivalent) of the Successor Entity as a result of such consideration to such extent) and the portion of such shares
shall be held in abeyance for the Holder until such time or times, as its right thereto would not result in the Holder and its
other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be delivered such shares to
the extent as if there had been no such limitation), and such security shall be reasonably satisfactory to the Holder, and with
an identical exercise price to the Exercise Price hereunder (such adjustments to the number of shares of capital stock and such
exercise price being for the purpose of protecting after the consummation or occurrence of such Fundamental Transaction the economic
value of this Warrant that was in effect immediately prior to the consummation or occurrence of such Fundamental Transaction, as
elected by the Holder solely at its option). Upon occurrence or consummation of the Fundamental Transaction, and it shall be a
required condition to the occurrence or consummation of such Fundamental Transaction that, the Company and the Successor Entity
or Successor Entities shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any
time after the occurrence or consummation of the Fundamental Transaction, as elected by the Holder solely at its option, shares
of Common Stock, Successor Capital Stock or, in lieu of the shares of Common Stock or Successor Capital Stock (or other securities,
cash, assets or other property purchasable 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 for purposes of clarification may continue to be shares of Common Stock, if any, that the Holder would have been entitled
to receive upon the happening of such Fundamental Transaction or the record, eligibility or other determination date for the event
resulting in such Fundamental Transaction, had this Warrant been exercised immediately prior to such Fundamental Transaction or
the record, eligibility or other determination date for the event resulting in such Fundamental Transaction (without regard to
any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. In addition to
and not in substitution for any other rights hereunder, prior to the occurrence or consummation of any Fundamental Transaction
pursuant to which holders of shares of Common Stock are entitled to receive securities, cash, assets or other property with respect
to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision
to ensure that, and any applicable Successor Entity or Successor Entities shall ensure that, and it shall be a required condition
to the occurrence or consummation of such Corporate Event that, the Holder will thereafter have the right to receive upon exercise
of this Warrant at any time after the occurrence or consummation of the Corporate Event, shares of Common Stock or Successor Capital
Stock or, if so elected by the Holder, in lieu of the shares of Common Stock (or other securities, cash, assets or other property)
purchasable upon the exercise of this Warrant prior to such Corporate Event (but not in lieu of such items still issuable under
Sections 3 and 4(a), which shall continue to be receivable on the Common Stock or on the such shares of stock, securities, cash,
assets or any other property otherwise receivable with respect to or in exchange for shares of Common Stock), such shares of stock,
securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights and any
shares of Common Stock) which the Holder would have been entitled to receive upon the occurrence or consummation of such Corporate
Event or the record, eligibility or other determination date for the event resulting in such Corporate Event, had this Warrant
been exercised immediately prior to such Corporate Event or the record, eligibility or other determination date for the event resulting
in such Corporate Event (without regard to any limitations on exercise of this Warrant). Provision made pursuant to the preceding
sentence shall be in a form and substance reasonably satisfactory to the Holder. The provisions of this Section 4(b) shall apply
similarly and equally to successive Fundamental Transactions and Corporate Events. Notwithstanding the foregoing, the Holder may
elect, in its sole discretion, by delivery of written notice to the Company, to waive this Section 4(b) and allow the Company to
enter into or be a party to a Fundamental Transaction without the assumption of this Warrant pursuant to the provisions of this
Section 4(b), provided, however, that any such waiver shall only bind the Holder with respect to this Warrant and
not the Holder with respect to any other warrant or other securities of the Company or any holder of other Series O Warrants.

(c)       Notwithstanding
anything herein to the contrary, the Company shall be required to obtain the prior written consent of the Required Holders to enter
into, allow and/or consummate a Fundamental Transaction other than one in which a Successor Entity that is a publicly traded corporation
whose stock is quoted or listed for trading on an Eligible Market assumes this Warrant such that the Warrant shall be exercisable
for the publicly traded Common Stock of such Successor Entity.


 


5.            NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation or 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 of 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 Series O 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 Series O Warrants, the Required Reserve Amount to effect the exercise of
the Series O Warrants then outstanding (without regard to any limitations on exercise).


 


6.          WARRANT
HOLDER NOT DEEMED A SHAREHOLDER. 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 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.

10.        GOVERNING
LAW; JURISDICTION; JURY TRIAL. 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. The Company hereby irrevocably waives
personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof
to the Company at the address set forth in the Securities Purchase Agreement and agrees that such service shall constitute good
and sufficient service of process and notice thereof. 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, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling
in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, 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 all the Holders 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 or electronic mail within
two (2) Business Days after 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
two (2) Business Days after such disputed determination or arithmetic calculation being submitted to the Holder, then the Company
shall, within one (1) Business Day submit via facsimile (a) the disputed determination of the Exercise Price to an independent,
reputable investment bank selected by the Holder and approved by the Company, such approval not to be unreasonably withheld or
delayed, or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant,
approved by the Holder, such approval not to be unreasonably withheld or delayed. 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 (10) 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 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.         TRANSFER.This

laws, and, except for the Warrant Shares sold pursuant to an effective registration statement or pursuant to Rule 144 under the

any applicable state securities law, except pursuant to sales registered or exempted under the 1933 Act.

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).
