registered holder of this Warrant or its permitted assigns (the “Holder”) is entitled, upon the terms and subject
to the limitations on exercise and the conditions set forth in this Warrant, at any time or times on or after the Authorized Shares

Section
1.          Definitions. Capitalized terms used in this Warrant have the meanings set forth in this Warrant including Section
14 below; provided, however, that capitalized terms used and not otherwise defined in this Warrant shall have the meanings
set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated July 2, 2012, by
and among the Company, the Holder and the other investors referred to therein.

Section
2.          Exercise.


a)          Exercise of Warrant. Subject to the terms and conditions of this Warrant (including,
without limitation, the limitation set forth in Section 2(d)), this Warrant may be exercised by the Holder on any day on
or after the Authorized Shares Increase Date, in whole or in part (but not as to fractional shares), by delivery of a written
notice, in the form attached to this Warrant as Exhibit A or in such other form as is
satisfactory to the Company (the “Exercise Notice”), of the Holder’s election to exercise this Warrant.
Within two (2) Trading Days following the Exercise Notice, the Holder shall make payment to the Company of an amount equal to
the applicable Exercise Price (as defined in Section 2(b)) multiplied by the number of Warrant Shares as to which this Warrant
is being exercised (the “Aggregate Exercise Price”) in cash or by wire transfer of immediately available funds,
or by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 2(c)).
The Holder shall not be required to surrender this Warrant in order to effect an exercise under this
Warrant, unless the Holder has purchased all of the Warrant Shares available under this Warrant
and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant
to the Company for cancellation as soon as practicable after the date the final Exercise Notice is delivered to the Company. Execution
and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation
of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares.
On or before the second Trading Day following the date on which the Company has received the Exercise Notice, the Company shall
transmit by email or facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Company’s
transfer agent for the Common Stock (the “Transfer Agent”). The Company shall deliver any objection to the
Exercise Notice on or before the second Trading Day following the date on which the Company has received the Exercise Notice.
In the event of any discrepancy or dispute as to the remaining number of Warrant Shares, the records of the Company and the Holder’s
broker or brokers shall be controlling and determinative in the absence of manifest error. On or before the third Trading Day
following the date on which the Company has received the Exercise Notice, but not in any event prior to the time the Holder
has delivered the Aggregate Exercise Price (or notice of a Cashless Exercise) (the “Share
Delivery Date”), the Company shall, (X)  provided that the Transfer Agent is participating in the Direct
Registration System (including any successor thereto, “DRS”) or The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program (including any successor thereto, the “FAST Program”), upon the
request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such
exercise to either the Holder’s or its designee’s balance account with DTC through its Deposit /Withdrawal At Custodian
system, or to the Holder’s or its designee’s direct registration account, or (Y), if the Transfer Agent is not participating
in either the DRS or FAST Program, issue and dispatch by overnight courier to the address as specified in the Exercise Notice,
a certificate (which shall be unlegended, provided that the Warrant Shares subject to the Exercise Notice are included
in an effective Registration Statement or all applicable requirements of Rule 144, including the holding period thereof, are met,
and subject in all cases to requirements of, and compliance with,






    	2



    	 



    
 


securities
laws then in effect), registered in the Company’s share register in the name of the Holder or its designee, for the number
of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon delivery of the Exercise 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 or DRS 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 2(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 Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance with
Section 4(b)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise
under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. The Company shall pay any
and all taxes that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant; provided,
however, that the Company shall not be required to pay any stamp or other tax or governmental charge required to be paid
in connection with any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other
than that of the Holder or any other Attribution Party (as defined below), and in the event that any such transfer is involved,
the Company shall not be required to effect any such transfer until such tax or other charge shall have been paid or it has been
established to the Company’s reasonable satisfaction that no such tax or other charge is due. The Holder shall be responsible
for all income tax liability that may arise as a result of holding or transferring this Warrant. The Holder and any assignee,
by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase
of a portion of the Warrant Shares under this Warrant, the number of Warrant Shares available for purchase under this Warrant
at any given time may be less than the amount stated on the face of this Warrant.


b)          Exercise Price. The exercise price per share of Common Stock issuable under this Warrant shall be $0.01, subject to adjustment
pursuant to the terms of this Warrant (the “Exercise Price”).


c)          Cashless Exercise. Upon exercise of this Warrant, in lieu of making the cash payment otherwise contemplated to be made
to the Company upon such exercise, the Holder can elect instead to receive upon such exercise the “Net Number” of
shares of Common Stock determined according to the following formula (a “Cashless Exercise”):


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


           
                         B


For
purposes of the foregoing formula:


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


 






    	3



    	 



    
  


B
= the Weighted Average Price of the shares of Common Stock on the Trading Day immediately preceding the date of the Exercise
Notice; and


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


 


d)          Beneficial Ownership Limitation on Exercises. 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, to the extent that after
giving effect to such exercise, such Holder together with the other Attribution Parties (as defined below) collectively would
beneficially own in excess of 9.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately
after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially
owned by 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 shares of Common Stock which would be issuable upon
(i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder or any other Attribution Party
and (ii) 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, including the SPA 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 2(d). For purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d)
of the Exchange Act. For purposes of determining the number of 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 (1) 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, as the case may be, (2) 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 a 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 such 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 2(d), 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, where such request indicates that it is being made pursuant to this Warrant, the Company
shall within two Trading Days confirm orally and in writing or by electronic mail to the Holder the number of shares of Common
Stock then outstanding.






    	4



    	 



    
 


In
any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise
of securities of the Company, including the SPA Warrants, by the Holder and 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
the 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 Exchange 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 (with such increase not effective until the sixty-first (61st) day after delivery of such
notice) or decrease the Maximum Percentage 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 Principal Market or applicable Eligible Market for issuances of shares of Common Stock in excess of such amount or (y)
the Company is not subject to rules of the Principal Market or applicable Eligible 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 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 the SPA Warrants
that is not an Attribution Party. For purposes of clarity, the shares of Common Stock underlying 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 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(d) 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(d) 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.


As
used in this Warrant, “Attribution Parties” means, collectively, the following Persons and entities: (i) QVT
Fund IV LP, (ii) QVT Fund V LP, (iii) Quintessence Fund L.P., (iv) QVT Financial LP, (v) QVT Financial GP LLC, (vi) QVT Associates
GP LLC, and (vii) any other investment vehicle, including any other funds, feeder funds or managed accounts, currently, or from
time to time after the Issuance Date, directly or indirectly managed or advised by QVT Financial LP or any of its Affiliates or
principals, (viii) any direct or indirect Affiliates of the Holder or any of the foregoing, (ix) any Person acting or who could
be deemed to be acting as a Group together with the Holder






    	5



    	 



    
 


 or
any of the foregoing and (x) any other Persons whose beneficial ownership of the Company’s Common Stock would or could be
aggregated with the Holder’s and the other Attribution Parties for purposes of Section 13(d) of the Exchange Act. For clarity,
the purpose of the foregoing is to subject collectively the Holder and all other Attribution Parties to the Maximum Percentage.


e)          Fractional Shares. 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 pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price.


f)           Failure to Timely Deliver Shares. In addition to any other rights available to the Holder, if the Company fails to deliver
to the Holder a certificate or the certificates representing the Warrant Shares or to credit the Holder’s balance account
with DRS or DTC or through the FAST Program for such number of Warrant Shares to which the Holder is entitled upon the Holder’s
exercise pursuant to an exercise on or before the Share Delivery Date, and if after such date the Holder purchases (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 that the Holder anticipated receiving from the Company upon such exercise
(a “Buy-In”), then the Company shall, within three 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 or credit such Holder’s balance
account with DRS or DTC (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver
to the Holder a certificate or certificates representing such Common Stock or credit the Holder’s balance account with DRS
or DTC and  pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product
of (A) such number of shares of Common Stock, times (B) the Weighted Average Price of the Common Stock on the date of
the event giving rise to the Company’s obligation to deliver such certificate. The Company shall be liable for all payments
to the Holder pursuant to this Section 2(f) and such payments shall be a liability and debt obligation of the Company, and the
Holder shall be a creditor of the Company with respect to such obligation, that is immediately due and payable pursuant to and
in accordance with this Section 2(f).


Section
3.          Certain Adjustments.


a)      
Stock Dividends and Splits. If the Company, at any time from and after the Issuance Date and while this Warrant is outstanding:
(i) 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, or (ii) combines (by combination, reverse stock split
or otherwise) one or more classes of its outstanding shares of Common






    	6



    	 



    
 


 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 3(a) shall become effective
at the close of business on the date the subdivision or combination becomes effective. If any event occurs of the type contemplated
by the provisions of this Section 3(a) 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 to the holders of the Company’s
equity securities), then the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and
the number of Warrant Shares so as to protect the rights of the Holder as if it had been a holder of
the shares of Common Stock issuable upon exercise of this Warrant (without regard to any limitation on such exercise of this Warrant
and as if the Increased Shares Amendment had, as of such date, been adopted and become effective); provided, that
no such adjustment will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant
to this Section 3(a) in any manner that is adverse to the Holder.


b)      
Par Value. The Company shall not subdivide (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 if it would cause the Exercise Price to be less
than the par value of the Common Stock.


c)      
Rights Upon Distribution of Assets. If the Company shall declare or make any dividend or other distributions of its assets
(or rights to acquire its assets) to any or all holders of shares of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time
after the Issuance Date, then, in each such case, the Holder shall be entitled to participate in such
Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of
Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise of this Warrant
and as if the Increased Shares Amendment had, as of such date, been adopted and become effective) 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, 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 (or in the beneficial ownership
of any shares of Common Stock as a result of such Distribution 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 to be held similarly in
abeyance) to the same extent as if there had been no such limitation).

d)      
Fundamental Transaction.


(1)
         All Fundamental Transactions.


(a)          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,
each and every provision 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.


(b)          No
later than (i) thirty (30) days prior to the occurrence or consummation of any Fundamental Transaction or (ii) if later, the first
Trading Day following the date the Company first becomes aware of the occurrence or potential occurrence of a Fundamental Transaction,
the Company shall deliver written notice thereof via facsimile and overnight courier to the holders of SPA Warrants (a “Fundamental
Transaction Notice”).


(c)          The
provisions of this Section 3(d) shall apply to each and every Fundamental Transaction and multiple Fundamental Transactions.


(2)          Non-Company
Controlled Fundamental Transactions.


(a)          Immediately
upon exercise of this Warrant following the occurrence or consummation of a Non-Company Controlled Fundamental Transaction, the
Company and the Successor Entity or Successor Entities shall deliver to the Holder 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
Non-Company Controlled Fundamental Transaction or the record, eligibility or other determination date for the event resulting
in such Non-Company Controlled Fundamental Transaction, had this Warrant been exercised immediately prior to such Non-Company
Controlled Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Non-Company
Controlled Fundamental Transaction (without regard to any limitations on the exercise of this Warrant
and as if the Increased Shares Amendment had, as of such date, been adopted and become effective), as adjusted in accordance
with the provisions of this Warrant.

(b)          Immediately
upon occurrence or consummation of a Non-Company Controlled Fundamental Transaction (and it shall be a required condition to the
occurrence or consummation of such Non-Company Controlled Fundamental Transaction that) the Company and the Successor Entity or
Successor Entities shall deliver to the Holder confirmation that the Company and the Successor Entity or Successor Entities shall
comply with the requirements set forth in this Warrant.


(c)          It
shall be a required condition to the occurrence or consummation of such Non-Company Controlled Fundamental Transaction that, under
no circumstances may the Holder be treated better or in a manner more advantageous than the holders of shares of Common Stock
in such Non-Company Controlled Fundamental Transaction pursuant to the terms of this Section 3(d).


(3)          Company
Controlled Fundamental Transactions.


(a)          Upon occurrence or consummation of a Company Controlled Fundamental Transaction, the Company and the Successor Entity or Successor
Entities shall deliver to the Holder upon exercise of this Warrant immediately upon the occurrence or consummation of Company
Controlled Fundamental Transaction or at any time thereafter, as elected by the Holder solely at its option, (i) shares of Common
Stock or Successor Capital Stock, (ii) 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 Company Controlled Fundamental Transaction
or the record, eligibility or other determination date for the event resulting in such Company Controlled Fundamental Transaction,
had this Warrant been exercised immediately prior to such Company Controlled Fundamental Transaction or the record, eligibility
or other determination date for the event resulting in such Company Controlled Fundamental Transaction (without regard to any
limitations on the exercise of this Warrant and as if the Increased Shares Amendment had, as of such
date, been adopted and become effective), as adjusted in accordance with the provisions of this Warrant, or (iii) pursuant
to and in accordance with the following paragraph, a cash payment equal to the Black Scholes Value of
the elected portion of this Warrant (or, at the election of the Holder, any elected portion of this Warrant).


(b)          (i)
Without limiting in any manner any other rights, obligations and terms set forth in this Section 3(d) and in addition to any other
rights set forth in this Section 3(d), and regardless of any provision in any agreement, contract or other document to which the
Company or any Successor Entity is a party (including, without limitation the Purchase Agreement
and the Warrants) that may be construed to limit the Company’s or any Successor Entity’s obligation to make a payment
pursuant to this paragraph, at the delivery of a request of the Holder (which request shall be made solely at the option of the
Holder and the Holder has the sole right to determine whether or not to exercise such option) to the Company, the Successor Entity
and/or the Successor






    	9



    	 



    



Entities (a “Fundamental Transaction Early Termination Notice”) at any time and
from time to time after the Holder becoming aware in any way of a Company Controlled Fundamental Transaction (including through
receipt of a Fundamental Transaction Notice), the Company and/or the Successor Entity and/or
Successor Entities, jointly and severally, shall (i) comply with their escrow obligations as set forth
in the following paragraph and (ii) pay to the Holder cash in an amount equal to the Fundamental Transaction Warrant Early
Termination Price with respect to, as elected and determined by the Holder solely at its option,
all or a portion of the Warrant. The Fundamental Transaction Early Termination Notice shall
indicate the portion (which may be all of this Warrant) of this Warrant with respect to which the Holder is electing to receive
the Fundamental Transaction Warrant Early Termination Price. The Company and the Successor Entity
or Successor Entities, jointly and severally, shall become liable for the Fundamental Transaction
Warrant Early Termination Price and such payment shall be a liability and debt obligation of the Company
and the Successor Entity or Successor Entities, jointly and severally, and the Holder shall
be a creditor of the Company and the Successor Entity or Successor Entities, jointly and severally, with
respect to such obligation, that is immediately due and payable upon the delivery by the Holder of the Fundamental Transaction
Early Termination Notice. The Holder may deliver one or more Fundamental Transaction Early Termination Notices pursuant to this
Warrant with respect to all or any portion of the Warrant.


(ii)The
Company and the Successor Entity or Successor Entities shall not effect a Company Controlled Fundamental Transaction unless and
shall not provide for or make any payment (of cash or otherwise) relating to any such Company Controlled Fundamental Transaction
unless (and it shall be a required condition to the occurrence or consummation of any Company Controlled Fundamental Transaction
that) the Company and the Successor Entity or Successor Entities, jointly and severally, shall first (i) place into an escrow
account with an independent escrow agent, at least three (3) Business Days prior to the closing date of the Company Controlled
Fundamental Transaction (the “Fundamental Transaction Escrow Deadline”), an amount of cash equal to the Fundamental
Transaction Warrant Early Termination Price with respect to all SPA Warrants, to be paid by the Company and the Successor Entity
or Successor Entities, jointly and severally, in accordance with this Section 3(d)(3)(b) to holders of SPA Warrants that deliver
any Fundamental Transaction Early Termination Notice in accordance with the preceding paragraph, and (ii) pay to the holders of
SPA Warrants that deliver any Fundamental Transaction Early Termination Notice on or prior to the closing date of the Company
Controlled Fundamental Transaction their applicable Fundamental Transaction Warrant Early Termination Price. Within
five (5) Business Days after receipt of a Fundamental Transaction Early Termination Notice (or, if later, on the effective date
of the Company Controlled Fundamental Transaction), the Company and the Successor Entity or Successor Entities, jointly
and severally, shall pay or shall instruct the escrow agent to pay the Fundamental Transaction Warrant Early Termination Price
to all applicable holders of SPA Warrants that have delivered a Fundamental Transaction Early Termination Notice. For purposes
of determining the amount required to be placed in escrow pursuant to the provisions of this paragraph and without affecting the
amount of the actual Fundamental Transaction Warrant Early Termination Price, the calculation of the price referred to in clause
(iv) of the definition of Black Scholes Value with respect to Closing Sale Price of the Common Stock shall be determined based
on the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the date that the funds are deposited with
the escrow agent.

(iii)Following
the receipt of a Fundamental Transaction Early Termination Notice from the Holder, in the event that the Company or any Successor
Entity attempts to consummate a Company Controlled Fundamental Transaction without placing the Fundamental Transaction Warrant
Early Termination Price in escrow in accordance with the provisions above or without payment of the Fundamental Transaction Warrant
Early Termination Price to the Holder prior to consummation of such Company Controlled Fundamental Transaction, the Holder shall
have the right to apply for an injunction in any state or federal courts sitting in the City of New York, borough of Manhattan
to prevent the closing of such Company Controlled Fundamental Transaction until the Fundamental Transaction Warrant Early Termination
Price is paid to the Holder and the Company and the Successor Entity or Successor Entities agree to waive any requirement by the
Holder to post any bond in connection therewith. It shall be a required condition precedent to the consummation of any Company
Controlled Fundamental Transaction that, and no Company Controlled Fundamental Transaction may be consummated unless, the Company
and the Successor Entity or Successor Entities, jointly and severally, have either (i) complied with the escrow deposit required
above or (ii) confirmed with the Holder in writing that the Holder is not requiring such escrow deposit prior to consummation
of the Company Controlled Fundamental Transaction.


(iv)Notwithstanding
anything to the contrary in this Section 3(d), until the Fundamental Transaction Warrant Early Termination Price is paid in full,
this Warrant may be exercised, in whole or in part, by the Holder into shares of Common Stock and any part of this Warrant not
so exercised or redeemed shall retain all of the other rights set forth in this Warrant.


(v)The
parties hereto agree that in the event of the early termination of any portion of this Warrant under this Section 3(d)(3)(b),
the Holder’s actual damages would be uncertain and difficult to estimate because of the parties’ inability to predict
the losses of the Holder, future Common Stock market prices, other opportunities of the Holder had
it not invested in this Warrant and the uncertainty of the availability of a suitable substitute investment opportunity for the
Holder. Accordingly, any payment due under this Section 3(d)(3)(b) is intended by the parties to be, and shall be deemed,
a fair and reasonable estimate of the amount required to compensate the Holder for the Holder’s loss of its investment opportunity
and not a penalty. In the event that the Holder delivers a Fundamental Transaction Early Termination Notice pursuant to a Clause
C Fundamental Transaction and the Company pays in full to the Holder, pursuant to and in accordance with the terms of this Section
3(d)(3)(b), the related Fundamental Transaction Warrant Early Termination Price, the Holder shall not be entitled to any other
payment for damages under this Warrant solely in connection with such Clause C Fundamental Transaction.

(c)          
In the event of a Company Controlled Fundamental Transaction, 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, then solely at the request of
the Holder (and in addition to and without limiting any other right under this Warrant), such Successor Entity or Entities shall
deliver 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. Such security shall be exercisable for a number
of shares of capital stock of the Successor Entity and/or Successor Entities (the “Successor Capital Stock”)
equivalent (as set forth below) 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 and as if the Increased Shares Amendment
had, as of such date, been adopted and become effective) prior to such Company Controlled Fundamental Transaction. The
number of shares of Successor Capital Stock to be delivered to Holder shall equal the quotient of (A) the Black Scholes Value
of this Warrant at the time of consummation of such Company Controlled Fundamental Transaction divided by (B) the per share Closing
Sale Price of such Successor Capital Stock on the Trading Day immediately prior to the consummation or occurrence of the Company
Controlled Fundamental Transaction. Such security shall be satisfactory to the Holder, and with an identical exercise price to
the Exercise Price under this Warrant. The parties acknowledge that the determination of the number of shares of Successor Capital
Stock as set forth above is for the purpose of protecting after the consummation or occurrence of such Company Controlled Fundamental
Transaction the economic value of this Warrant that was in effect immediately prior to the consummation or occurrence of such
Company Controlled Fundamental Transaction, as elected by the Holder solely at its option.


(d)          Any
security issuable or potentially issuable to the Holder pursuant to the terms of this Warrant upon a Company Controlled Fundamental
Transaction shall be registered and freely tradable by the Holder without any restriction or limitation or the requirement to
be subject to any holding period pursuant to any applicable securities laws.


(4)          Clarifications.
For purposes of clarification and without limiting any rights set forth in this Warrant, (i) upon any Fundamental Transaction
or at any time thereafter, at the Holder’s request, the Holder shall have the right to require the Company and/or the Successor
Entity and/or Successor Entities, jointly and severally, to deliver upon the occurrence or consummation (and it shall be a required
condition to such occurrence or consummation) of the Fundamental Transaction, in satisfaction of this Warrant (but not in lieu
of Distributions and Purchase Rights still issuable under Sections 3(c) and 3(e), 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 Fundamental Transaction or the record, eligibility or other determination
date for the event resulting in






    	12



    	 



    



such Fundamental Transaction, had this Warrant been exercised in full (without regard to any limitations
on exercise of this Warrant and as if the Increased Shares Amendment had, as of such date, been adopted
and become effective) with such Holder becoming a holder of such shares of Common Stock issuable upon such exercise immediately
prior to such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental
Transaction; (ii) the purpose of this Section 3(d) is to assure that in all circumstances of any Fundamental Transaction or similar
corporate type transaction, the Holder will have rights no worse (and, other than in connection with a Company Controlled Fundamental
Transaction, no better) in any way than or adversely affected relative to or in any manner not as advantageous (or, other than
in connection with a Company Controlled Fundamental Transaction, disadvantageous) as those of a holder of the number of shares
of Common Stock issuable upon exercise of this Warrant (without regard to any limitations on exercise of this Warrant
and as if the Increased Shares Amendment had, as of such date, been adopted and become effective) as if this Warrant had
already been exercised into Common Stock (without regard to any limitations on exercise of this Warrant and as if the Increased
Shares Amendment had, as of such date, been adopted and become effective) prior to such Fundamental Transaction or the record,
eligibility or other determination date for the event resulting in such Fundamental Transaction and shall not receive worse (or,
other than in connection with a Company Controlled Fundamental Transaction, better) treatment, be prejudiced or adversely affected
relative to or treated in any manner not as advantageous (or, other than in connection with a Company Controlled Fundamental Transaction,
disadvantageous) as the treatment afforded to any holders of shares of Common Stock in such Fundamental Transaction or similar
corporate type transaction by virtue of the fact that the Holder holds this Warrant rather than the shares of Common Stock issuable
upon exercise of this Warrant (without regard to any limitations on exercise of this Warrant and as if the Increased Shares Amendment
had, as of such date, been adopted and become effective); (iii) it is specifically intended that no Person attempt to structure
a transaction in any manner to circumvent the intent of this Section 3(d) and therefore the provisions
of this Section 3(d) shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this
Section 3(d) to the extent necessary to correct this Section 3(d) or any portion of this Section 3(d) which may be defective or
inconsistent with the intended treatment of the Holder or to make changes or supplements necessary or desirable to properly give
effect to such treatment as no worse (and, other than in connection with a Company Controlled Fundamental Transaction,
no better) in any way than or adversely affected relative to or in any manner not as advantageous
(or, other than in connection with a Company Controlled Fundamental Transaction, disadvantageous) as
a holder of the number of shares of Common Stock issuable upon exercise of this Warrant (without regard to any limitations on
exercise of this Warrant and as if the Increased Shares Amendment had, as of such date, been adopted and become effective) in
any Fundamental Transaction or similar corporate type transaction as contained in this Warrant;
(iv) it is specifically intended, among other events and transactions, that any tender offer or similar transaction made with
respect to the Company or 50% or more of the Common Stock shall be deemed a Fundamental Transaction under this Warrant; (v) notwithstanding
any provision of this Warrant that may be interpreted to the contrary, the Holder has an express right to receive at least the
same proportion and amount of cash, if


 



    	13



    	 



    



 


any, per Warrant Share (provided, that the foregoing shall in no way limit the rights of
the Holder, solely at its option, to receive the Fundamental Transaction Warrant Early Termination Price entirely in cash) that
each holder of a share of Common Stock is entitled to receive from the Company or any Successor Entity or Successor Entities,
upon any Fundamental Transaction (such as a cash merger or cash tender offer) where cash comprises any portion of the applicable
consideration or payment, that it would have been entitled to receive had it exercised this Warrant prior to the 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 and as if the Increased Shares Amendment
had, as of such date, been adopted and become effective); (vi) the provisions of this Section 3(d) may not be waived, modified
or otherwise implemented otherwise than in strict conformity with the intention of this Section 3(d) and shall apply to a successor
holder of this Warrant and any Successor Entity or Successor Entities; and (vii) notwithstanding any provision of this Warrant,
the Purchase Agreement or any other agreement or contract that could in any way be read to limit the right of the Holder to elect
and receive at any time in perpetuity any payments pursuant to Section 5(a), no provision of this
Warrant, the Purchase Agreement or any other agreement or contract shall limit the rights of the Holder (including, without
limitation, the right to receive any Redemption Price) to receive at any time in perpetuity any
payments pursuant to Section 5(a).


(5)          Section
5(a) Payment Obligation. Notwithstanding anything set forth in this Section 3(d) or anywhere else in this Warrant or in any
other Transaction Document, nothing in this Section 3(d) or anywhere else in this Warrant or in any other Transaction Document
shall limit the rights of the Holder (including, without limitation, the right to receive any Redemption Price) pursuant to Section
5(a).


e)      
Purchase Rights. In addition to any adjustments pursuant to Section 3 above, if at any time after the Issuance Date
and prior to the Expiration Date the Company grants, issues or sells any Options, Convertible Securities or rights to purchase
stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase
Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon
complete exercise of this Warrant (without regard to any limitations on exercise of this Warrant and as if the Increased Shares
Amendment had, as of such date, been adopted and become effective) 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 Common Shares as a result of such Purchase Right
to such extent) and such Purchase Right (and beneficial ownership) to such extent shall be held in abeyance for the Holder until
such time or times as its right






    	14



    	 



    



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 to be held similarly in abeyance) to
the same extent as if there had been no such limitation).


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.


Section
4.Transfer of Warrant.


a)      
Transferability. Subject to compliance with applicable securities laws, this Warrant and all rights under this Warrant
are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated
agent, together with the Assignment Form, in the form attached to this Warrant as Exhibit B or in such other form as is
satisfactory to the Company, duly executed by the Holder or its agent or attorney and, if any, 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 or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant
not so assigned, 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 prior to having a new Warrant issued. 


b)      
New Warrants. This Warrant may be divided or combined with other Series B Warrants upon presentation of this Warrant at
the aforesaid office of the Company or its designated agent, 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. Notwithstanding anything to the contrary
in this Section 4(b), in no event shall this Warrant be subdivided into units of less than 5,000 Warrant Shares (as adjusted for
stock splits, stock dividends, recapitalizations or similar events) and such new Warrants shall not be further subdivided. Subject
to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute
and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or 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.



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 of this Warrant from time to time. The Company may
deem and treat the registered Holder of this Warrant as the absolute owner of this Warrant for the purpose of any exercise of
this Warrant or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section
5.          Increase in Authorized Capital and Reservation of Warrant Shares.


a)      
Increase in Authorized Common Stock. 


(1)          Following
the Issuance Date, the Company shall take all corporate action necessary to call a meeting of its stockholders (the “Stockholders
Meeting”), as soon as practicable, but in no event later than September 30, 2012 (the “First Authorized Shares
Increase Deadline”), for the purpose of seeking approval of the Company’s stockholders to amend the Company’s
Certificate of Incorporation to increase the number of shares of the Company’s authorized Common Stock from 100,000,000
shares to no less than 200,000,000 shares (the “Increased Shares Stockholder Approval”). No later than one
(1) Trading Day following the Increased Shares Stockholder Approval, the Company shall file with the Secretary of State of Delaware
a certificate of amendment to the Company’s Certificate of Incorporation to effect the Increased Shares Stockholder Approval
such that the number of authorized shares of the Company’s Common Stock is at least 200,000,000 shares, which certificate
of amendment shall provide that it shall become immediately effective upon filing (such filing, the “Amendment Filing”,
and the occurrence of both the Increased Shares Stockholder Approval and the Amendment Filing, the “Increased Shares
Amendment”). The date on which the Increased Shares Amendment becomes effective is referred to in this Warrant as the
“Authorized Shares Increase Date”. Without limiting the Company’s obligations under this Section 5, for
the avoidance of doubt, the Company shall not be prohibited from calling additional Stockholders Meetings from time to time.


(2)
       If the Authorized Shares Increase Date has not occurred on or prior to the First Authorized Shares Increase Deadline, the
Company shall take all corporate action necessary to call one or more other Stockholders Meetings, as soon as practicable and
as often as practicable, but in no event later than June 30, 2013 (the “Second Authorized Shares Increase
Deadline”), for the purpose of again seeking approval of the Company’s stockholders for the Increased Shares
Stockholder Approval.


(3)
        If the Authorized Shares Increase Date has not occurred on or prior to the First Authorized Shares Increase Deadline, and
notwithstanding any provision of this Warrant, the Purchase Agreement or any other agreement or contract that could in any
way be read to limit the right of the Holder to elect and receive the following, the Holder at any time and from time to time
thereafter (in perpetuity and with no limitation in time) may require the Company, by delivering one or more notices in
writing (each a “Put Notice” and the date of each such Put Notice, a “Put Notice
Date”), to redeem this Warrant (or, at the option of the Holder, any portion of this Warrant) in full (without
regard to any limitations on exercise of this Warrant), by paying to the Holder cash (the “Redemption
Price”) by wire transfer of immediately available funds in an amount equal to the product of (i) the number of
Warrant Shares set forth by the Holder in each applicable Put Notice and (ii) the highest Redemption Price Average on any
Trading Day during the Put Period. Such Redemption Price shall be paid (i) in the event of a Put Notice delivered prior to
June 30, 2013, on June 30, 2013, and (ii) in the event of a Put Notice delivered on or after June 30, 2013, within five (5)
Trading Days after the applicable Put Notice Date.






    	16



    	 



    



(4)          At
any time and from time to time (in perpetuity and with no limitation in time) after delivering any Put Notice (including, without
limitation, at any time and from time to time prior to or after the Second Authorized Shares Increase Deadline), the Holder shall
have the right, at the Holder’s option, to deliver a notice to the Company (the “Withdrawal Put Notice”),
withdrawing any specified Put Notice previously delivered pursuant to this Warrant and such withdrawal shall be immediately effective,
unless otherwise specified in such Withdrawal Put Notice. For the avoidance of doubt, the delivery of any Withdrawal Put Notice
shall not prejudice in any respect the right of the Holder to deliver any future Put Notice even as to the same Warrant Shares
covered by the withdrawn Put Notices.


(5)          The
Company shall become liable for the applicable Redemption Price relating to any Put Notice immediately following the applicable
Put Notice Date and such amounts shall be a liability and debt obligation of the Company, and the Holder shall be a creditor of
the Company with respect to such obligation, that is immediately due and payable upon the delivery by the Holder of the applicable
Put Notice.


(6)            Each
time the Company seeks the approval of its stockholders for the Increased Shares Stockholder Approval, the Company’s Board
of Directors shall recommend to the Company’s stockholders that the stockholders vote in favor of the Increased Shares Stockholder
Approval at the Stockholders Meeting and take all commercially reasonable action to solicit the approval of the stockholders for
the Increased Shares Stockholder Approval, including filing a proxy statement in a form reasonably acceptable to the Required
Holders and complying with Section 14(a) of the Exchange Act and the rules promulgated thereunder in relation to such proxy statement
and any form of proxy to be sent to the stockholders of the Company in connection with the Stockholders Meeting.


(7)          The
parties hereto agree that in the event of the Company’s failure to adopt the Increased Shares Amendment in accordance with
the terms of this Section 5(a), the Holder’s actual damages would be uncertain and difficult to estimate because of the
parties’ inability to predict the losses of the Holder, future Common Stock market prices, other opportunities of the Holder
had it not invested in this Warrant and the uncertainty of the availability of a suitable substitute investment opportunity for
the Holder. Accordingly, any payment due under this Section 5(a) is intended by the parties to be, and shall be deemed, a fair
and reasonable estimate of the amount required to compensate the Holder for the Holder’s loss of its investment opportunity
as a result of the Company’s failure to perform and not a penalty.






    	17



    	 



    



(8)           If
the Authorized Shares Increase Date has not occurred on or prior to the First Authorized Shares Increase Deadline, then (in addition
to all other rights the Holder has under this Warrant, including without limitation, this Section 5(a)) until either (x) the occurrence
of the Authorized Shares Increase Date or (y) such time that no Series B Warrants are outstanding (such period, the “Interest
Accrual Period”), the Company shall be obligated to pay a cash amount to the Holder by wire transfer of immediately
available funds in an amount equal to the Interest Amount. Any accrued and unpaid Interest Amount shall be paid semi-annually
on each January 1 and July 1 (each such period, commencing as for the first payment of the Interest Amount pursuant to this Section
on the Issuance Date, and otherwise commencing on the date of the payment of the immediately preceding Interest Amount in accordance
with this Section, an “Interest Period”) during the Interest Accrual Period. For purposes of this Section 5(a)(8),
“Interest Amount” shall mean an amount calculated at 10% per annum of the product of (i) the number of shares
underlying the Series B Warrants outstanding during the applicable Interest Period (pro rated for Series B Warrants outstanding
for part of the applicable Interest Period) and (ii) the greater of (x) $0.50 (as adjusted for stock splits, reverse stock splits,
stock dividends, stock combinations, recapitalizations, reorganizations or similar events as necessary to preserve the economic
amount that would result if no such event occurred) and (y) the arithmetic average of the Weighted Average Prices of the Common
Stock for each Trading Day during the applicable Interest Period. The Company shall become liable for the Interest Amount and
such amounts shall be a liability and debt obligation of the Company, and the Holder shall be a creditor of the Company with respect
to such obligation, that is immediately due and payable when due pursuant to the terms of this Warrant.


(9)          Notwithstanding
any provision of this Warrant, the Purchase Agreement or any other agreement or contract that could in any way be read to limit
the right of the Holder to elect and receive at any time in perpetuity any payments pursuant to this Section 5(a), no provision
of this Warrant, the Purchase Agreement or any other agreement or contract shall limit the rights
of the Holder (including, without limitation, the right to receive any Redemption Price) to receive at
any time in perpetuity any payments pursuant to this Section 5(a). 


b)      
Reservation. The Company covenants that it will at all times on and after the Authorized Shares Increase Date reserve and
keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose
of enabling it to issue Warrant Shares upon exercise of this Warrant as provided in this Warrant, the number of shares of Common
Stock which are then issuable and deliverable upon the exercise of this entire Warrant (without regard to any limitations on the
exercise of this Warrant and taking into account the adjustments and restrictions in Section 3),
free from preemptive or any other contingent purchase rights of Persons other than the Holder . The Company covenants that all
shares of Common Stock so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance
with the terms of this Warrant, will be duly and validly authorized, issued and fully paid and nonassessable. The Company will
take all such actions as may be reasonably necessary to assure that such shares of Common Stock may be issued as provided in this
Warrant without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated
quotation system upon which the Common Stock may be listed.






    	18



    	 



    



Section
6.          Miscellaneous.


a)      
No Rights as Stockholder Until Exercise. Except as otherwise provided in this Warrant, this Warrant does not entitle the
Holder to any voting rights nor any right to receive notice of meetings or any other rights as a stockholder of the Company prior
to the exercise of this Warrant as set forth in Section 2.


b)      
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.


c)      
Noncircumvention. The Company covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation,
Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of
this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required
to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase
the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect,
(ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant and (iii) shall, from and after the Authorized
Shares Increase Date and for so long as this Warrant is 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 this Warrant, the number
of shares of Common Stock as shall from time to time be necessary to effect the exercise of this Warrant (without regard to any
limitations on exercise of this Warrant).


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 in this Warrant shall not be a Business Day, then, such action may be taken or such right may be exercised
on the next Business Day.



    	19



    	 



    
 


e)      
Governing Law and Jurisdiction. 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 under this Warrant or in connection herewith
or with any transaction contemplated in this Warrant or discussed in this Warrant, 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 such party at the address it set forth on the signature page to this Warrant
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained in
this Warrant shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained
in this Warrant 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 UNDER
THIS WARRANT OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.


f)       
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 email or facsimile
within two Trading Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the
Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares
within five Trading Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company
shall, within two Trading Days submit via email or facsimile (a) the disputed determination of the Exercise Price to an independent,
reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of
the Warrant Shares to the Company’s independent, outside accountant. The Company shall use reasonable best efforts to cause
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 10 Trading 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. The expenses of the investment bank and accountant will be borne by the Company, unless the
investment bank or accountant determines that the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares by the Company was correct, in which case the expenses of the investment bank and accountant will be borne by the Holder.

g)      
Restrictions and Rule 144. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant are
not registered. For purposes of Rule 144 promulgated under the Securities Act, as in effect on the date of this Warrant, it is
intended that, and the Company acknowledges and agrees that, 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 Warrant was originally issued pursuant to the Purchase Agreement. The Company agrees to take all actions, including, without
limitation, the issuance by its legal counsel of any necessary legal opinions required by its transfer agent or otherwise, necessary
to issue the Warrant Shares in a Cashless Exercise without restriction and not containing any restrictive legends without the
need for any action by the Holder; provided, that, in the case of a Cashless Exercise effected between the six month anniversary
and the one year anniversary of the Issuance Date, the Company has satisfied the current public information requirement under
Rule 144(c).


h)      
Nonwaiver. No course of dealing or any delay or failure to exercise any right under this Warrant on the part of Holder
shall operate as a waiver of such right or otherwise prejudice Holder’s rights, powers or remedies. 


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 in accordance with the notice provisions of the Purchase Agreement. The Company shall provide the Holder with
prompt written notice of all actions taken pursuant to this Warrant, including, in reasonable detail, a description of such action
and the reason or reasons therefor. Without limiting the generality of the foregoing, the Company will give written notice to
the Holder (i) reasonably promptly following any adjustment of the Exercise Price or the number of Warrant Shares, setting
forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least 10 days prior to the
date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares
of Common Stock, (B) with respect to any events that give rights to the Holder pursuant to Section 3(e) of this Warrant or
(C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation; provided,
that in each case, such information shall be made known to the public prior to or in conjunction with such notice being provided
to the Holder.


j)       
Limitation of Liability. No provision of this Warrant, in the absence of any affirmative action by Holder to exercise this
Warrant to purchase Warrant Shares, and no enumeration in this Warrant 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,
