offering (“ Offering ”) of shares of the Company’s common stock, par value $0.01 per share (“ Common
Stock ”) and Common Stock Purchase Warrants (“Warrants”), evidencing the right of the holders thereof
(each, a “ Holder ”) to purchase up to an aggregate of ___________ shares of Common Stock (the “ Warrant

WHEREAS,
the Company has filed with the Securities and Exchange Commission a Registration Statement on Form S-1 (File No. 333-

Agreement.


 


3.             WARRANTS.


 


3.1              BOOK-ENTRY
WARRANT CERTIFICATES. The Warrants shall initially be issuable in book-entry registration only and evidenced by a global Warrant
Certificate (the “ Book-Entry Warrant Certificates ”). All of the Warrants shall initially be represented by
one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company (“Depository”) and registered
in the name of Cede & Co., a nominee of the Depository. Ownership of beneficial interests in the Warrants shall be shown
on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depository or its nominee
for each Book-Entry Warrant Certificate or (ii) institutions that have accounts with the Depository (such institution, with
respect to a Warrant in its account, a “Participant”). If the Depository subsequently ceases to make its book-entry
settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding other arrangements for book-entry
settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in,
book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation
each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to each Holder a Warrant Certificate.

Warrant Agent either manually or facsimile signature and shall not be valid for any purpose unless so countersigned. In case any
officer of the Company who shall have signed any of the Warrant Certificates shall cease to be such officer of the Company before
countersignature by the Warrant Agent and issuance and delivery by the Company, such Warrant Certificates, nevertheless, may be
countersigned by the Warrant Agent, issued and delivered with the same force and effect as though the person who signed such Warrant
Certificate had not ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company
by any person who, at the actual date of the execution of such Warrant Certificate, shall be a proper officer of the Company to
sign such Warrant Certificate, although at the date of the execution of this Agreement any such person was not such an officer.

3.3.         REGISTRATION.


 


3.3.1              WARRANT
REGISTER. The Warrant Agent shall maintain books (“Warrant Register”) for the registration of original issuance
and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and
register the Warrants in the names of the respective Holders thereof in such denominations and otherwise in accordance with instructions
delivered to the Warrant Agent by the Company.


 


3.3.2              REGISTERED
HOLDER. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and
treat the person in whose name such Warrant shall be registered upon the Warrant Register (“ registered holder ”),
as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other
writing on the Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise
thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.


 


4.            TERMS
AND EXERCISE OF WARRANTS


 


4.1           WARRANT
PRICE. Each Warrant shall, when countersigned by the Warrant Agent, entitle the registered Holder, subject to the provisions
of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the
price of $0.__ per whole share, subject to the adjustments provided in Section 5 hereof and in the last sentence of this Section 4.1.
The term “Exercise Price” as used in this Agreement refers to the price per share at which Common Stock may
be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Exercise Price at any time prior
to the Expiration Date.


 


4.2           DURATION
OF WARRANTS. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the date
of issuance, which is expected to occur on October __, 2014 (“Initial Exercise Date”), and terminating at 5:00
p.m., New York City time on the five (5) year anniversary of the Initial Exercise Date (“Expiration Date”).
Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect
thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company in its sole discretion may
extend the duration of the Warrants by delaying the Expiration Date.


 


4.3          EXERCISE
OF WARRANTS.


 


4.3.1              EXERCISE
OF WARRANT. Exercise of the purchase rights represented by the Warrant may be made, in whole or in part, at any time or times
on or after the Initial Exercise Date and on or before the Expiration Date by delivery to the Company (or such other office or
agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing
on the books of the Company) of a duly executed e-mailed copy of the Notice of Exercise form annexed hereto, subject to the Company’s
confirmation of receipt of the e-mail. Within three (3) Trading Days following the date of exercise as aforesaid, the Holder
shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer of immediately
available funds, or pursuant to the cashless exercise procedure specified in Section 2(c) below, if such cashless exercise
procedure is available and is specified in the applicable Notice of Exercise. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender the Warrant to the Company until the Holder has purchased all of the Warrant
Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender the Warrant to
the Company for cancellation within three (3) Trading Days after the date the final Notice of Exercise is delivered to the
Company. Partial exercises of the Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder
shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable
number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased
and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form within one (1) Business
Day after receipt of such notice.


 




    	3



    	 



    

 


4.3.2       CASHLESS
EXERCISE. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to the Holders, then the Warrants may only be exercised, in whole
or in part, at such time by means of a “cashless exercise” in which the Holders shall be entitled to receive that number
of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


(A) = the VWAP on the Trading Day immediately preceding
the date on which a Holder elects to exercise the Warrant by means of a “cashless exercise,” as set forth in the applicable
Exercise Notice;


 


(B) = the Exercise Price of the Warrant, as adjusted
hereunder; and


 


(X) = the number of Warrant Shares that would be issuable
upon exercise of such Warrant in accordance with the terms of the Warrant if such exercise were by means of a cash exercise rather
than a cashless exercise.


 


Upon receipt of an Exercise Notice for a cashless exercise,
the Warrant Agent will promptly deliver a copy of the Exercise Notice to the Company to confirm the number of Warrant Shares issuable
in connection with the cashless exercise. The Company shall calculate and transmit to the Warrant Agent, and the Warrant Agent
shall have no obligation under this section to calculate, the number of Warrant Shares issuable in connection with the cashless
exercise.


 


4.3.3              DELIVERY
OF WARRANT SHARES UPON EXERCISE. Warrant Shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder
by crediting the account of the Holder’s prime broker with The Depository Trust Company through its system (“DWAC”)
system if the Company is then a participant in such system and either (A) there is an effective registration statement permitting
the issuance of the Warrant Shares to the Holder or (B) the Warrant is being exercised via cashless exercise, and otherwise
by physical delivery to the address specified by the Holder in the Notice of Exercise, in each case by the date that is three (3) Trading
Days after the latest of (A) the delivery to the Company of the Notice of Exercise and receipt of the DWAC request from the
Holder’s prime broker (if applicable), (B) surrender of the Warrant (if required) and (C) payment of the aggregate
Exercise Price as set forth above (including by cashless exercise, if permitted) (such date, the “ Warrant Share Delivery
Date ”). The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated to
be named therein shall be deemed to have become the holder of record of such shares for all purposes, as of the date the Warrant
has been properly exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all
taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having
been paid.


 


4.3.4              DELIVERY
OF NEW WARRANTS UPON EXERCISE. If a Warrant shall have been exercised in part, the Company shall, at the request of the Holder
and upon surrender of the Warrant, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver
to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by the Warrant,
which new Warrant shall in all other respects be identical to the Warrant.


 




    	4



    	 



    

 


4.3.5              RESCISSION
RIGHTS. If the Company fails to cause the Transfer Agent to transmit either to the Holder’s prime broker the Warrant
Shares or to the Holder a certificate or the certificates representing the Warrant Shares, as applicable pursuant to Section 2(d)(i)
hereof by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.


 


4.3.6              COMPENSATION
FOR BUY-IN ON FAILURE TO TIMELY DELIVER SHARES UPON EXERCISE. In addition to any other rights available to the Holder, if the
Company fails to instruct the Transfer Agent to transmit to the Holder’s prime broker the Warrant Shares, or to the Holder
a certificate or the certificates representing the Warrant Shares pursuant to an exercise on or before the Warrant Share Delivery
Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the
Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of
the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company
shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including
brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying
(1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at
issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the
option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise
was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common
Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example,
if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise
of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of
the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company
written notice indicating the amounts payable to the Holder in respect of the Buy-In and evidence of the amount of such loss. Nothing
herein 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 upon exercise of the Warrant as required pursuant to the terms hereof


 




    	5



    	 



    

 


4.3.7              HOLDER’S
EXERCISE LIMITATIONS. The Company shall not effect any exercise of the Warrant, and the Holder shall not have the right to
exercise any portion of the Warrant, pursuant to Section 4 or otherwise, to the extent that after giving effect to such issuance
after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and
any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates) would beneficially own in
excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares
of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable
upon exercise of the Warrant with respect to which such determination is being made, but shall exclude the number of shares of
Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of the Warrant beneficially
owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of
any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation
on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates. Except
as set forth in the preceding sentence, for purposes of this Section 4.3.7, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the
Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the
Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 4.3.7 applies, the determination of whether the Warrant is exercisable (in relation
to other securities owned by the Holder together with any Affiliates) and of which portion of the Warrant is exercisable shall
be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination
of whether the Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of
which portion of the Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and neither the Company
nor the Warrant Agent shall have any obligation to verify or confirm the accuracy of such determination and shall have no liability
for exercises of the Warrant that are not in compliance with the Beneficial Ownership Limitation. In addition, a determination
as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and
the rules and regulations promulgated thereunder. For purposes of this Section 4.3.7, in determining the number of outstanding
shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s
most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement
by the Company or (C) a more recent written notice by the Company or the Warrant Agent setting forth the number of shares
of Common Stock outstanding. Upon the written or oral request of the Holder, the Company shall within two (2) Trading Days
confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company, including the Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of
Common Stock was reported. The “Beneficial Ownership Limitation” shall be 9.98% of the number of shares of the Common
Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of the Warrant.
Upon delivery of a written notice to the Company, the Holder may from time
to time increase (with such increase not effective until the sixty-first (61st) day after delivery of such notice) or
decrease the Beneficial Ownership Limitation to any other percentage not in excess of 19.99% (except that such increased percentage
may exceed 19.99% in the event that (a) the Company obtains the approval of its stockholders as required by the applicable rules
of the Trading Market on which the Common Stock is traded for issuances of shares of Common Stock in excess of such amount or (b)
the Company is not subject to rules of a Trading Market limiting issuances of shares of Common Stock in excess of such amount)
as specified in such notice; provided that (i) any such increase in the Beneficial Ownership Limitation 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 its affiliates and not to any other holder of the Warrant that is not an affiliate of such Holder.
For purposes of clarity, the shares of Common Stock underlying this Warrant in excess of the Beneficial Ownership Limitation 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 Exchange 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 4.3.7 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 4.3.7 or to make changes
or supplements necessary or desirable to properly give effect to such limitation. The limitation as contained in this paragraph
may not be waived and shall apply to a successor holder of the Warrant.


 


4.3.8              VALID
ISSUANCE. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be
validly issued, fully paid and non-assessable.


 


4.3.9              DATE
OF ISSUANCE. Each person in whose name any such certificate for shares of Common Stock is issued shall for all purposes be
deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Exercise
Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment
is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such
shares at the close of business on the next succeeding date on which the stock transfer books are open.

5.            ADJUSTMENTS.


 


5.1              STOCK
DIVIDENDS AND SPLITS. If the Company, at any time while a Warrant is outstanding: (i) pays a dividend or otherwise makes
a distribution or distributions, in each case payable in shares of its Common Stock, to all holders of Common Stock (and not to
the Holders) (excluding, for avoidance of doubt, any shares of Common Stock issued by the Company upon exercise of the Warrant),
(ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines (including by way
of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then in each case the Exercise Price
shall be multiplied by a fraction, of which the numerator shall be the number of shares of Common Stock (excluding treasury shares,
if any) outstanding at 5:00 p.m. (New York City time) on the Trading Day immediately before such event, and of which the denominator
shall be the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such event,
and the number of shares issuable upon exercise of the Warrant shall be proportionately adjusted such that the aggregate Exercise
Price of the Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately
prior to 9:00 a.m. (New York city time) on the Ex-Dividend Date for such dividend or distribution or the effective date of such
subdivision or combination, as the case may be. “Ex-Dividend Date” means, when used with respect to any dividend,
distribution or issuance, the first date on which the share of Common Stock trade on the Trading Market, regular way, without the
right to receive the relevant dividend, distribution or issuance.


 


5.2              SUBSEQUENT
RIGHTS OFFERINGS. In addition to any adjustments pursuant to Section 5.1 above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of the Warrant (without regard to
any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) 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 Beneficial Ownership Limitation, 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 Beneficial Ownership Limitation).


 


5.3              PRO
RATA DISTRIBUTIONS. If the Company, at any time while a Warrant is outstanding, shall distribute to all holders of Common Stock
(and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe
for or purchase any security other than the Common Stock, then in each such case the Exercise Price shall be adjusted by multiplying
the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of
which the numerator shall be such VWAP on such record date less the then per share fair market value at such record date of the
portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of the Common Stock as determined
by the Board of Directors in good faith. In each case the adjustments shall be described in a statement provided to the Holder
of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common
Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record
date mentioned above.

5.4              FUNDAMENTAL
TRANSACTION. If, at any time while the Warrant is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person and the Company is not the
surviving corporation, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance
or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) the Company,
directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of
the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged
for other securities, cash or property, or (iv) the Company, directly or indirectly, in one or more related transactions consummates
a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization,
spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group of Persons acquires
more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other
Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase
agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise
of the Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise
immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation
in Section 2(e) on the exercise of the Warrant), the number of shares of Common Stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and any additional consideration (the “ Alternate Consideration
”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which the
Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 4.3.7
on the exercise of the Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately
adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share
of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration
in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of
Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the
Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of the Warrant following
such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction that is (1) an
all cash transaction, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a
Fundamental Transaction involving a person or entity not traded on a national securities exchange, including, but not limited to,
the NYSE MKT LLC, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market, the Company or any Successor
Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after,
the consummation of the Fundamental Transaction, purchase this Warrant from the Holder by paying to the Holder an amount of cash
equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental
Transaction. “Black Scholes Value” means the value of the Warrant based on the Black and Scholes Option Pricing
Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day
of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable
Fundamental Transaction and the Expiration Date, (B) an expected volatility equal to the greater of 100% and the average of
10, 20 and 30-day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public
announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall
be the greater of (i) the weighted average price of the Common Stock for the Trading Day immediately preceding the date of announcement
of the applicable  Fundamental Transaction, (ii) the weighted average price of the Common Stock for the Trading Day immediately
following the date of announcement of the applicable  Fundamental Transaction and (iii) the weighted average price of the
Common Stock for the Trading Day immediately preceding the date of consummation of the applicable  Fundamental Transaction,
and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Expiration Date. The Company shall cause any successor entity in a Fundamental Transaction in which the Company
is not the survivor (the “ Successor Entity ”) to assume in writing all of the obligations of the Company under
the Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written
agreements and shall, at the option of the Holder, deliver to the Holder in exchange for the Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to the Warrant which is exercisable for a
corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common
Stock acquirable and receivable upon exercise of the Warrant (without regard to any limitations on the exercise of the 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 number of shares of capital stock and such exercise price being for the purpose
of protecting the economic value of the Warrant immediately prior to the consummation of such Fundamental Transaction), and which
is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor
Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions
of the 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 the
Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

5.5              CALCULATIONS.
All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may
be. For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given
date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 


5.6              NOTICES
OF CHANGES IN WARRANT. Upon every adjustment of the Exercise Price or the number of shares issuable upon exercise of a Warrant,
the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Exercise Price resulting from
such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a
Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon
the occurrence of any event specified in this Section 5, then, in any such event, the Company shall give written notice to
the Warrant Holder, at the last address set forth for such Holder in the warrant register, of the record date or the effective
date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.


 


5.7              NO
FRACTIONAL SHARES. Notwithstanding any provision contained in the Agreement to the contrary, no fractional shares or scrip
representing fractional shares shall be issued upon the exercise of Warrants. As to any fraction of a share which the Holder would
otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect
of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.


 


5.8              FORM
OF WARRANT. The form of Warrant need not be changed because of any adjustment pursuant to this Section 5, and Warrants
issued after such adjustment may state the same Exercise Price and the same number of shares as is stated in the Warrants initially
issued pursuant to this Agreement. However, the Company may at any time in its sole discretion make any change in the form of Warrant
that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned,
whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders

case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the
Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the
date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record
is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger,
sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders
of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail
such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be
specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information
regarding the Company or any of the Subsidiaries, the Company shall simultaneously disclose such information in compliance with
applicable securities laws. The Holder shall remain entitled to exercise the Warrant during the period commencing on the date of

surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in
exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be
made and indicating whether the new Warrants must also bear a restrictive legend.

execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority,
powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall
make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming

d)           Mechanics
of Exercise.


 


i.              Delivery
of Warrant Shares Upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder
by crediting the account of the Holder’s prime broker with The Depository Trust Company through its system (“DWAC”)
system if the Company is then a participant in such system and either (A) there is an effective registration statement permitting
the issuance of the Warrant Shares to the Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise
by physical delivery to the address specified by the Holder in the Notice of Exercise, in each case by the date that is three (3) Trading
Days after the latest of (A) the delivery to the Company of the Notice of Exercise and receipt of the DWAC request from the
Holder’s prime broker (if applicable), (B) surrender of this Warrant (if required) and (C) payment of the aggregate
Exercise Price as set forth above (including by cashless exercise, if permitted) (such date, the “ Warrant Share Delivery
Date ”). The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated to
be named therein shall be deemed to have become the holder of record of such shares for all purposes, as of the date this Warrant
has been properly exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all
taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having
been paid.


 


ii.              Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of
the Holder and upon surrender of this Warrant, at the time of delivery of the certificate or certificates representing Warrant
Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called
for by this Warrant, which new Warrant shall in all other respects be identical to this Warrant.


 




    	3



    	 



    

 


iii.              Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit either to the Holder’s prime broker the Warrant
Shares or to the Holder a certificate or the certificates representing the Warrant Shares, as applicable pursuant to Section 2(d)(i)
hereof by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.


 


iv.              Compensation
for Buy-In on Failure to Timely Deliver Shares Upon Exercise. In addition to any other rights available to the Holder,
if the Company fails to instruct the Transfer Agent to transmit to the Holder’s prime broker the Warrant Shares, or to the
Holder a certificate or the certificates representing the Warrant Shares pursuant to an exercise on or before the Warrant Share
Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise)
or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder
of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company
shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including
brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying
(1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at
issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the
option of the Holder, either reinstate the portion of this Warrant and equivalent number of Warrant Shares for which such exercise
was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common
Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example,
if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise
of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of
the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Company shall only be obligated
to pay the Holder pursuant to this Section 2(d)(iv) upon the Holder’s delivery to the Company of a written notice indicating
the amounts payable to the Holder in respect of the Buy-In and evidence of the amount of such loss. Nothing herein 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 upon exercise of this Warrant as required pursuant to the terms hereof.


 


v.               No Fractional Shares or Scrip. No fractional
shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share
which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash
adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to
the next whole share.


 


vi.              Charges,
Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue
or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall
be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed
by the Holder; provided, however, that in the event certificates for Warrant Shares are to be issued in a name other
than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto
duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any
Notice of Exercise.

vii.            Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise
of this Warrant, pursuant to the terms hereof.


 


e)              Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and the Holder shall not have the right
to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such
issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates,
and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates) would beneficially own
in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of
shares of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable
upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of
Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially
owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of
any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation
on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates. Except
as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the
Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the
Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation
to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall
be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of
which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall
have no obligation to verify or confirm the accuracy of such determination and shall have no liability for exercises of this Warrant
that are not in compliance with the Beneficial Ownership Limitation. In addition, a determination as to any group status as contemplated
above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, the Holder may rely on
the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report
filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent
written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the
written or oral request of the Holder, the Company shall within two (2) Trading Days confirm orally and in writing to the Holder
the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder
or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial
Ownership Limitation” shall be 9.98% of the number of shares of the Common Stock outstanding immediately after giving effect
to the issuance of shares of Common Stock issuable upon exercise of this Warrant. Upon delivery of a written notice to the Company,
the Holder may from time to time increase (with such increase not effective until the sixty-first (61st) day after delivery
of such notice) or decrease the Beneficial Ownership Limitation to any other percentage not in excess of 19.99% (except that such
increased percentage may exceed 19.99% in the event that (x) the Company obtains the approval of its stockholders as required by
the applicable rules of the Trading Market on which the Common Stock is traded for issuances of shares of Common Stock in excess
of such amount or (y) the Company is not subject to rules of a Trading Market limiting issuances of shares of Common Stock in excess
of such amount) as specified in such notice; provided that (i) any such increase in the Beneficial Ownership Limitation 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 its affiliates and not to any other holder of this Warrant that is not an affiliate
of such Holder. For purposes of clarity, the shares of Common Stock underlying this Warrant in excess of the Beneficial Ownership
Limitation 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 Exchange 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 2(e) 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
2(e) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation as contained
in this paragraph may not be waived and shall apply to a successor holder of this Warrant.

Section 3.              Certain
Adjustments.


 


a)              Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a dividend or otherwise
makes a distribution or distributions, in each case payable in shares of its Common Stock, to all holders of Common Stock (and
not to the Holders) (excluding, for avoidance of doubt, any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines (including
by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then in each case the Exercise
Price shall be multiplied by a fraction, of which the numerator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding at 5:00 p.m. (New York City time) on the Trading Day immediately before such event, and of which the
denominator shall be the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of,
such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate
Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective
immediately prior to 9:00 a.m. (New York city time) on the Ex-Dividend Date for such dividend or distribution or the effective
date of such subdivision or combination, as the case may be. “ Ex-Dividend Date ” means, when used with respect
to any dividend, distribution or issuance, the first date on which the share of Common Stock trade on the Trading Market, regular
way, without the right to receive the relevant dividend, distribution or issuance.


 


b)              [INTENTIONALLY
DELETED]


 


c)              Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants,
issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the
record holders of any class of shares of Common Stock (the “ Purchase Rights ”), then the Holder will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to
any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) 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 Beneficial Ownership Limitation, 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 Beneficial Ownership Limitation).


 




    	6



    	 



    

 


d)              Pro
Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common
Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants
to subscribe for or purchase any security other than the Common Stock (which shall be subject to Section 3(c)), then in each
such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the
VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the
then per share fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable
to one outstanding share of the Common Stock as determined by the Board of Directors in good faith. In each case the adjustments
shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or
such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution
is made and shall become effective immediately after the record date mentioned above.


 


e)              Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or
more related transactions effects any merger or consolidation of the Company with or into another Person and the Company is not
the surviving corporation, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer,
conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) the
Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization
of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged
for other securities, cash or property, or (iv) the Company, directly or indirectly, in one or more related transactions consummates
a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization,
spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group of Persons acquires
more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other
Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase
agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise
of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise
immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation
in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the
exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted
to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder
shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction that is (1) an all cash transaction,
(2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a Fundamental Transaction
involving a person or entity not traded on a national securities exchange, including, but not limited to, the NYSE MKT LLC, the
Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market, the Company or any Successor Entity (as defined
below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation
of the Fundamental Transaction, purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black
Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction.
“Black Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained
from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation
of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding
to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the average of 10, 20 and
30-day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement
of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the greater
of (i) the weighted average price of the Common Stock for the Trading Day immediately preceding the date of announcement of the
applicable  Fundamental Transaction, (ii) the weighted average price of the Common Stock for the Trading Day immediately following
the date of announcement of the applicable  Fundamental Transaction and (iii) the weighted average price of the Common Stock
for the Trading Day immediately preceding the date of consummation of the applicable  Fundamental Transaction, and (D) a
remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and
the Termination Date. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the
survivor (the “ Successor Entity ”) to assume 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(e) pursuant to written agreements
and shall, at the option of the Holder, 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 which is exercisable for a corresponding number
of shares of capital stock of such Successor Entity (or its parent entity) 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 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), and which is reasonably
satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity
shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this
Warrant 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.

f)            Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case
may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given
date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 


g)            Notice
to Holder.


 


i.              Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company
shall promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.


 




    	8



    	 



    

 


ii.              Notice
to Allow Exercise by Holder. If during the term in which this Warrant may be exercised by the Holder (A) the Company
shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a
special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to
all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class, (D) the
approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any
consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the
Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the
Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then,
in each case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register
of the Company, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or
warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such
dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is
expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities,
cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided
that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate
action required to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material,
non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously disclose such information
in compliance with applicable securities laws. The Holder shall remain entitled to exercise this Warrant during the period commencing
on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth
herein.


 


Section 4. Transfer of Warrant.


 


a)              Transferability.
Subject to compliance with applicable securities laws, this Warrant and all rights hereunder are transferable, in whole and not
in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written
assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds
sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment,
the Company shall execute and deliver a new Warrant in the name of the assignee and this Warrant shall promptly be cancelled. This
Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without
having a new Warrant issued.


 


b)              New
Warrants. This Warrant may be combined with other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder
or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such combination,
the Company shall execute and deliver a new Warrant or Warrants in exchange for this Warrant or Warrants to be combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall include reference to the initial issuance date set forth
on the first page of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant
thereto and the Warrant number.


 


c)              Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and
for all other purposes, absent actual written notice to the contrary.


 


Section 5.              Miscellaneous.


 


a)              No
Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other
rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i).


 


b)             Delegation of Duties.
The Company may delegate the performance of any of its duties contemplated hereunder to the Warrant Agent pursuant to the terms
set forth in the Warrant Agreement.


 




    	9



    	 



    

 


c)              Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate
of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate. Applicants for a replacement Warrant
under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable
charges as the Company may prescribe.


 


d)              Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding
Business Day.


 


e)              No
Inconsistent Actions. Except and to the extent as waived or consented to by the Holder, the Company shall not by any action,
including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation,
merger, 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, but will at all times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against
impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant
Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all
such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations,
exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company
to perform its obligations under this Warrant.


 


f)              Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in
accordance with the provisions of the Purchase Agreement.


 


g)              Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions
upon resale imposed by state and federal securities laws unless the Holder utilizes the cashless exercise provisions hereof.


 


h)              Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of the Holder shall
operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies. Without limiting any other
provision of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision
of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall
be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those
of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its
rights, powers or remedies hereunder.


 


i)              Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered
to the registered Holder at the last address as it shall appear upon the Warrant Register of the Company.


 


j)              Limitation
of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for
the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

k)              Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to seek specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate.


 


l)              Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall
inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted
assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant
and shall be enforceable by the Holder or holder of Warrant Shares.


 


m)             Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.


 


n)              Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.


 


o)              Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.
