 FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the undersigned, FLO

entitled to subscribe for and purchase, during the Term (as hereinafter defined), up to              (            )
shares of the duly authorized, validly issued, fully paid and non-assessable Common Stock of the Issuer, at an exercise price per share equal to the Warrant Price, subject, however, to the provisions and upon the terms and conditions hereinafter set
forth. Capitalized terms used in this Warrant and not otherwise defined herein shall have the respective meanings specified in Section 8 hereof. 
 1. Term. The term of this Warrant shall commence on April 3, 2008 and, notwithstanding the following proviso, shall expire at 5:00 p.m., eastern time, on April 3, 2013; provided,
however, that, if there is an effective registration statement under the Securities Act covering the resale of any shares of Common Stock issuable upon exercise hereof, then the term of this Warrant shall expire with respect to such shares no
later than 5:00 p.m., eastern time, on the date that is 9 months after the date such registration statement became effective with respect to such shares (such period, the “Term”). 
 2. Method of Exercise; Payment; Issuance of New Warrant; Transfer and Exchange. 
 (a) Time of Exercise. The purchase rights represented by this Warrant may be exercised in whole or in part at any time during the Term.

 (b) Method of Exercise. 
 (i) The Holder hereof may exercise this Warrant, in whole or in part, by the surrender of this Warrant (with the exercise form attached
hereto duly executed) at the principal office of the Issuer, and by the payment to the Issuer of an amount of consideration therefor equal to the Warrant Price multiplied by the number of shares of Warrant Stock with respect to which this Warrant is
then being exercised, payable at such Holder’s election (A) by certified or official bank check or by wire transfer to an account designated by the Issuer, (B) by “cashless exercise” in accordance with subsection
(ii) of this Section 2(b), but only when there is no effective registration statement under the Securities Act covering the resale of the shares of Common Stock issuable upon exercise hereof or (C) by a combination of the foregoing
methods of payment selected by the Holder of this Warrant. 
 (ii) Cashless Exercise. Notwithstanding any provisions
herein to the contrary, if at any time after April 3, 2009, there is no effective registration statement under the Securities Act covering the resale of the shares of Common Stock issuable upon exercise hereof, then in lieu of exercising this
Warrant by payment of cash, the Holder may exercise this Warrant by a “cashless exercise” and shall receive the number of shares of Common Stock computed using the following formula: 
  

							
		  	X = Y - 	  	(A)(Y)	  	
		  		  	B	  	

					
			
	 Where
	  	X   =	  	the number of shares of Common Stock to be issued to the Holder;
			
		  	Y   =	  	the number of shares of Common Stock purchasable upon exercise of all of the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being
exercised;
			
		  	A   =	  	the Warrant Price; and
			
		  	B   =	  	the Per Share Market Value of one share of Common Stock on the date of exercise.

 (c) Issuance of Stock Certificates. In the event of any exercise of the rights represented
by this Warrant in accordance with and subject to the terms and conditions hereof, (i) certificates for the shares of Warrant Stock so purchased shall be dated the date of such exercise and delivered to the Holder hereof within a reasonable
time, not exceeding three (3) Trading Days after such exercise or, at the request of the Holder (provided that a registration statement under the Securities Act providing for the resale of the Warrant Stock is then in effect), issued and
delivered to the Depository Trust Company (“DTC”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) within a reasonable time, not exceeding three (3) Trading Days
after such exercise, and the Holder hereof shall be deemed for all purposes to be the holder of the shares of Warrant Stock so purchased as of the date of such exercise, and (ii) unless this Warrant has expired, a new Warrant representing the
number of shares of Warrant Stock, if any, with respect to which this Warrant shall not then have been exercised (less any amount thereof which shall have been canceled in payment or partial payment of the Warrant Price as hereinabove provided)
shall also be issued to the Holder hereof at the Issuer’s expense within such time. 
  

 - 2 - 

 (d) Transferability of Warrant. Subject to Section 2(f), this Warrant may be transferred by a
Holder without the consent of the Issuer. If transferred pursuant to this paragraph and subject to the provisions Section 2(f), this Warrant may be transferred on the books of the Issuer by the Holder hereof in person or by duly authorized
attorney, upon surrender of this Warrant at the principal office of the Issuer, properly endorsed (by the Holder executing an assignment in the form attached hereto) and upon payment of any necessary transfer tax or other governmental charge imposed
upon such transfer. This Warrant is exchangeable at the principal office of the Issuer for Warrants for the purchase of the same aggregate number of shares of Warrant Stock, each new Warrant to represent the right to purchase such number of shares
of Warrant Stock as the Holder hereof shall designate at the time of such exchange. All Warrants issued on transfers or exchanges shall be dated the Original Issue Date and shall be identical with this Warrant except as to the number of shares of
Warrant Stock issuable pursuant hereto. 
 (e) Continuing Rights of Holder. The Issuer will, at the time of or at any time after each
exercise of this Warrant, upon the request of the Holder hereof, acknowledge in writing the extent, if any, of its continuing obligation to afford to such Holder all rights to which such Holder shall continue to be entitled after such exercise in
accordance with the terms of this Warrant, provided, that if any such Holder shall fail to make any such request, the failure shall not affect the continuing obligation of the Issuer to afford such rights to such Holder. 
 (f) Compliance with Securities Laws. 
 (i) The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant or the shares of Warrant Stock to be issued upon exercise hereof are being acquired solely for the Holder’s own account and not
as a nominee for any other party, and not with a view to or in connection with a distribution, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Warrant Stock to be issued upon exercise hereof except
pursuant to an effective registration statement, or an exemption from registration, under the Securities Act and any applicable state securities laws. 
 (ii) Except as provided in paragraph (iii) below, this Warrant and all certificates representing shares of Warrant Stock issued upon exercise hereof shall be stamped or imprinted with a legend in substantially
the following form: 
 THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR FLO CORPORATION
SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED. 
  

 - 3 - 

 (iii) The restrictions imposed by this subsection (f) upon the transfer of this
Warrant or the shares of Warrant Stock to be purchased upon exercise hereof shall terminate (A) when such securities shall have been resold pursuant to an effective registration statement under the Securities Act, (B) upon the
Issuer’s receipt of an opinion of counsel, in form and substance reasonably satisfactory to the Issuer, addressed to the Issuer to the effect that such restrictions are no longer required to ensure compliance with the Securities Act and state
securities laws or (C) upon the Issuer’s receipt of other evidence reasonably satisfactory to the Issuer that such registration and qualification under the Securities Act and state securities laws are not required, which shall be deemed to
include a customary Rule 144 representation letter from the Holder. Whenever such restrictions shall cease and terminate as to any such securities, the holder thereof shall be entitled to receive from the Issuer (or its transfer agent and
registrar), without expense (other than applicable transfer taxes, if any), new Warrants (or, in the case of shares of Warrant Stock, new stock certificates) of like tenor not bearing the applicable legend required by paragraph (ii) above
relating to the Securities Act and state securities laws. 
 3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

 (a) Stock Fully Paid. The Issuer represents, warrants, covenants and agrees that all shares of Warrant Stock which may be issued
upon the exercise of this Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by or through Issuer. The Issuer further covenants and
agrees that during the period within which this Warrant may be exercised, the Issuer will at all times have authorized and reserved for the purpose of the issue upon exercise of this Warrant a sufficient number of shares of Common Stock to provide
for the exercise of this Warrant. 
 (b) Reservation. If any shares of Common Stock required to be reserved for issuance upon exercise
of this Warrant or as otherwise provided hereunder require registration or qualification with any governmental authority under any federal or state law before such shares may be so issued, the Issuer will in good faith use commercially reasonable
efforts as expeditiously as possible at its expense to cause such shares to be duly registered or qualified. If the Issuer shall list any shares of Common Stock on any securities exchange or market, it will, at its expense, list thereon, maintain
and increase when necessary such listing of all shares of Warrant Stock from time to time issued upon exercise of this Warrant or as otherwise provided hereunder (provided that such Warrant Stock has been registered pursuant to a then-effective
registration statement under the Securities Act), and, to the extent permissible under the applicable securities exchange rules, all unissued shares of Warrant Stock which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or market, and will maintain such listing of, any other securities which the Holder of this Warrant shall be entitled to receive upon the exercise of this Warrant if at the
time any securities of the same class shall be listed on such securities exchange or market by the Issuer. 
  

 - 4 - 

 (c) Covenants. The Issuer shall not by any action including, without limitation, amending the
Certificate of Incorporation or Bylaws of the Issuer or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other 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 the Holder hereof against impairment.
Without limiting the generality of the foregoing, the Issuer will (i) not permit the par value, if any, of its Common Stock to exceed the Warrant Price, (ii) not amend or modify any provision of the Certificate of Incorporation or Bylaws
of the Issuer in any manner that would adversely affect the rights of the Holders of the Warrants, (iii) take all such action as may be reasonably necessary in order that the Issuer may validly and legally issue fully paid and nonassessable
shares of Common Stock, free and clear of any liens, claims, encumbrances and restrictions (other than as provided herein or under applicable securities laws) upon the exercise of this Warrant, and (iv) use commercially reasonable efforts to
obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be reasonably necessary to enable the Issuer to perform its obligations under this Warrant. 
 (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or destruction, upon receipt of indemnity or security satisfactory to the Issuer or, in the case of any such mutilation, upon surrender and cancellation of such Warrant, the
Issuer will make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same number of shares of Common Stock. 
 4. Adjustment of Warrant Price. The price at which shares of Common Stock for which this Warrant is exercisable may be purchased upon exercise of
this Warrant shall be subject to adjustment from time to time as set forth in this Section 4. The Issuer shall give the Holder notice of any event described below which requires an adjustment pursuant to this Section 4 in accordance with
Section 5. 
 (a) Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale. 
 (i) In case the Issuer after the Original Issue Date shall do any of the following (each, a “Triggering Event”): (a)
consolidate with or merge into any other Person and the Issuer shall not be the continuing or surviving corporation of such consolidation or merger, or (b) permit any other Person to consolidate with or merge into the Issuer and the Issuer
shall be the continuing or surviving Person but, in connection with such consolidation or merger, any Capital Stock of the Issuer shall be changed into or exchanged for securities of any other Person or cash or any other property, or
(c) transfer all or substantially all of its properties or assets to any other Person, or (d) effect a capital reorganization or reclassification of its Capital Stock, then, and in the case of each such Triggering Event, proper provision
shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the Holder of this Warrant shall be entitled upon the exercise hereof at any time after the consummation of such Triggering Event, to the extent this
Warrant is not exercised prior to such Triggering Event, to receive at the Warrant Price in effect at the time immediately prior to the consummation of such Triggering Event in lieu of the Common Stock issuable upon such exercise of this Warrant
prior to such Triggering Event, the securities, cash and property to which such Holder would have been entitled upon the consummation of such Triggering Event if such Holder had exercised the rights represented by this Warrant immediately prior
thereto, subject to adjustments (subsequent to such corporate action) as nearly equivalent as possible to the adjustments provided for elsewhere in this Section 4. 
  

 - 5 - 

 (ii) Notwithstanding anything contained in this Warrant to the contrary, a Triggering
Event shall not be deemed to have occurred if, prior to the consummation thereof, each Person (other than the Issuer) which may be required to deliver any securities, cash or property upon the exercise of this Warrant as provided herein shall
assume, by written instrument delivered to, and reasonably satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer under this Warrant (and if the Issuer shall survive the consummation of such Triggering Event, such
assumption shall be in addition to, and shall not release the Issuer from, any continuing obligations of the Issuer under this Warrant) and (B) the obligation to deliver to such Holder such securities, cash or property as, in accordance with
the foregoing provisions of this subsection (a), such Holder shall be entitled to receive, and such Person shall have similarly delivered to such Holder an opinion of counsel for such Person, which counsel shall be reasonably satisfactory to such
Holder, or in the alternative, a written acknowledgement executed by the President or Chief Financial Officer of the Issuer, stating that this Warrant shall thereafter continue in full force and effect and the terms hereof (including, without
limitation, all of the provisions of this subsection (a)) shall be applicable to the securities, cash or property which such Person may be required to deliver upon any exercise of this Warrant or the exercise of any rights pursuant hereto.

 (b) Stock Dividends, Subdivisions and Combinations. If at any time the Issuer shall: 
 (i) take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend payable in, or other
distribution of, shares of Common Stock, 
 (ii) subdivide its outstanding shares of Common Stock into a larger number of
shares of Common Stock, or 
 (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common
Stock, 
 then (1) the number of shares of Common Stock for which this Warrant is exercisable immediately after the occurrence of any such event shall
be adjusted to equal the number of shares of Common Stock which a record holder of the same number of shares of Common Stock for which this Warrant is exercisable immediately prior to the occurrence of such event would own or be entitled to receive
after the happening of such event, and (2) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment. 
  

 - 6 - 

 (c) Certain Other Distributions. If at any time the Issuer shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive any dividend or other distribution of: 
 (i) cash (other than a
cash dividend payable out of earnings or earned surplus legally available for the payment of dividends under the laws of the jurisdiction of incorporation of the Issuer), 
 (ii) any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever
(other than cash, Common Stock Equivalents or Additional Shares of Common Stock), or 
 (iii) any warrants or other rights to
subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents or Additional Shares of Common Stock), 

then (1) the number of shares of Common Stock for which this Warrant is exercisable shall be adjusted to equal the product of the number of shares of Common
Stock for which this Warrant is exercisable immediately prior to such adjustment multiplied by a fraction (A) the numerator of which shall be the Per Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount allocable to one share of Common Stock of any such cash so distributable and of the fair value (as determined in good faith by the Board) of any and all such evidences of
indebtedness, shares of stock, other securities or property or warrants or other subscription or purchase rights so distributable, and (2) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such
adjustment. A reclassification of the Common Stock (other than a change in par value, or from par value to no par value or from no par value to par value) into shares of Common Stock and shares of any other class of stock shall be deemed a
distribution by the Issuer to the holders of its Common Stock of such shares of such other class of stock within the meaning of this Section 4(c) and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of
shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock within the meaning of Section 4(b). 
 (d) Superseding Adjustment. If, at any time after any adjustment of the number of shares of Common Stock for which this Warrant is exercisable and
the Warrant Price then in effect shall have been made pursuant to Section 4(c) as the result of any issuance of warrants, other rights or Common Stock Equivalents, and (i) such warrants or other rights, or the right of conversion or
exchange in such other Common Stock Equivalents, shall expire, and all or a portion of such warrants or other rights, or the right of conversion or exchange with respect to all or a portion of such other Common Stock Equivalents, as the case may be,
shall not have been exercised, or (ii) the consideration per share for which shares of Common Stock are issuable pursuant to such Common Stock Equivalents, shall be increased solely by virtue of provisions therein contained for an automatic
increase in such consideration per share upon the occurrence of a specified date or event, then for each outstanding Warrant such previous adjustment shall be rescinded and annulled and the Additional Shares of Common Stock which were deemed to have
been issued by virtue of the computation made in connection with the adjustment so rescinded and annulled shall no longer be deemed to have been issued by virtue of such computation. 

  

 - 7 - 

 
Upon the occurrence of an event set forth in this Section 4(d) above, there shall be a recomputation made of the effect of such Common Stock Equivalents
on the basis of: (i) treating the number of Additional Shares of Common Stock or other property, if any, theretofore actually issued or issuable pursuant to the previous exercise of any such warrants or other rights or any such right of
conversion or exchange, as having been issued on the date or dates of any such exercise and for the consideration actually received and receivable therefor, and (ii) treating any such Common Stock Equivalents which then remain outstanding as
having been granted or issued immediately after the time of such increase of the consideration per share for which shares of Common Stock or other property are issuable under such Common Stock Equivalents; whereupon a new adjustment of the number of
shares of Common Stock for which this Warrant is exercisable and the Warrant Price then in effect shall be made, which new adjustment shall supersede the previous adjustment so rescinded and annulled. 
 (e) Reduction of Warrant Exercise Price by Issuer. If the Issuer at any time while this Warrant is outstanding shall offer the Holder the
opportunity to exercise this Warrant at a price per share less than the applicable Warrant Price (each, a “Special Warrant Offer”), then the Warrant Price then in effect shall be reduced to the exercise price offered pursuant to the
Special Warrant Offer. Notwithstanding anything to the contrary contained in this Warrant, any adjustment of the Warrant Price made pursuant to this paragraph shall not survive the expiration of a Special Warrant Offer unless the Holder participates
in such Special Warrant Offer (to the fullest extent permitted by the Issuer). 
 (f) Other Provisions applicable to Adjustments under
this Section. The following provisions shall be applicable to the making of adjustments of the Warrant Price then in effect provided for in this Section 4: 
 (i) When Adjustments to Be Made. The adjustments required by this Section 4 shall be made whenever and as often as any
specified event requiring an adjustment shall occur, except that any adjustment of the number of shares of Common Stock for which this Warrant is exercisable that would otherwise be required may be postponed (except in the case of a subdivision or
combination of shares of the Common Stock, as provided for in Section 4(b)) up to, but not beyond the date of exercise if such adjustment either by itself or with other adjustments not previously made adds or subtracts less than one percent
(1%) of the shares of Common Stock for which this Warrant is exercisable immediately prior to the making of such adjustment. Any adjustment representing a change of less than such minimum amount (except as aforesaid) which is postponed shall be
carried forward and made as soon as such adjustment, together with other adjustments required by this Section 4 and not previously made, would result in a minimum adjustment or on the date of exercise. For the purpose of any adjustment, any
specified event shall be deemed to have occurred at the close of business on the date of its occurrence. 
 (ii) Fractional Interests. In computing adjustments under this
Section 4, fractional interests in Common Stock shall be taken into account to the nearest one one-hundredth (1/100th) of a share.

  

 - 8 - 

 (iii) When Adjustment Not Required. If the Issuer shall take a record of the
holders of its Common Stock for the purpose of entitling them to receive a dividend or distribution or subscription or purchase rights and shall, thereafter and before the distribution to stockholders thereof, legally abandon its plan to pay or
deliver such dividend, distribution, subscription or purchase rights, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

 (g) Form of Warrant after Adjustments. The form of this Warrant need not be changed because of any adjustments in the Warrant Price
or the number and kind of Securities purchasable upon the exercise of this Warrant. 
 (h) Escrow of Warrant Stock. If, after any
property becomes distributable pursuant to this Section 4 by reason of the taking of any record of the holders of Common Stock, but prior to the occurrence of the event for which such record is taken, the Holder exercises this Warrant, any
shares of Common Stock issuable upon exercise by reason of such adjustment shall be deemed the last shares of Common Stock for which this Warrant is exercised (notwithstanding any other provision to the contrary herein) and such shares or other
property shall be held in escrow for the Holder by the Issuer to be issued to the Holder upon and to the extent that the event actually takes place, upon payment of the current Warrant Price. Notwithstanding any other provision to the contrary
herein, if the event for which such record was taken fails to occur or is rescinded, then such escrowed shares shall be cancelled by the Issuer and escrowed property returned. 
 5. Notice of Adjustments. Whenever the Warrant Price shall be adjusted pursuant to Section 4 hereof (for purposes of this Section 5,
each an “adjustment”), the Issuer shall cause its Chief Financial Officer to prepare and execute a certificate setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated (including a description of the basis on which the Board made any determination hereunder), and the Warrant Price after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the
Holder of this Warrant promptly after each adjustment. 
 6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof. If any fraction of a share of Common Stock would, except for the provisions of this Section, be issuable on the exercise hereof, the Issuer will (i) round down and issue to the Holder only the largest
whole number of shares of Common Stock to which the Holder is otherwise entitled if the fraction of a share otherwise issuable is less than one-half, or (2) round up and issue to the Holder one additional share of Common Stock in addition to
the largest whole number of shares of Common Stock to which the Holder is otherwise entitled, if the fraction of a share of Common Stock otherwise issuable is equal to or greater than one-half. The determination as to whether or not any fractional
shares are issuable shall be based upon the total number of shares of Common Stock for which warrants are being exercised at any one time by the Holder hereof, not upon each warrant being exercised. 
 7. Ownership Cap and Certain Exercise Restrictions. (a) Notwithstanding anything to the contrary set forth in this Warrant, at no time may a
Holder of this Warrant exercise this Warrant if the number of shares of Common Stock to be issued pursuant to such exercise would exceed, when aggregated with all other shares of Common Stock beneficially owned (as determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules thereunder) by such Holder at such time, the number of shares of Common Stock which would result in such Holder beneficially
owning in 

  

 - 9 - 

 
excess of 4.9% of all of the Outstanding Common Stock at such time; provided, however, that upon the Holder of this Warrant providing the
Issuer with sixty-one (61) days notice (pursuant to Section 11 hereof) (the “Waiver Notice”) that such Holder would like to waive this Section 7(a) with regard to any or all shares of Common Stock issuable upon
exercise of this Warrant (and upon consent of the Issuer, which will not be unreasonably withheld), this Section 7(a) shall be of no force or effect with regard to those shares of Warrant Stock referenced in the Waiver Notice. 
 (b) Notwithstanding anything to the contrary set forth in Section 7 of this Warrant, at no time may the Holder exercise all or a portion of this
Warrant if the number of shares of Common Stock to be issued pursuant to such conversion, when aggregated with all other shares of Common Stock beneficially owned (as determined in accordance with Section 13(d) of the Exchange Act and the rules
thereunder) by the Holder at such time, would result in the Holder beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules thereunder) in excess of 9.9% of all of the Outstanding Common Stock at
such time. 
 (c) In the event that the operation of this Section 7 prevents the Holder from fully exercising this Warrant, such Holder
may elect to receive Series C Convertible Preferred Stock of the Issuer in lieu of shares of Common Stock convertible into the number of shares of Common Stock that would have been delivered to such Holder but for the limitations set forth in this
Section 7. The foregoing sentence shall not preclude the Holder from waiving at any time its rights to limit its ownership to 4.9% of all of the Outstanding Common Stock at such time in accordance with Section 7(a) hereof. “Series C
Convertible Preferred Stock” means a series of non-voting preferred stock of the Issuer with terms such that a holder thereof shall not be deemed a beneficial owner (as determined in accordance with Section 13(d) of the Exchange Act and
the rules thereunder) of the Common Stock issuable upon conversion thereof, and otherwise with terms similar to the Common Stock.

SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

	No.:                 	 		 	Number of Shares:                 
	Date of Issuance: August 24, 2007	 		 	

 FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the undersigned, FLO
Corporation, a Delaware corporation (together with its successors and assigns, the “Issuer”), hereby certifies that              or its registered assigns is
entitled to subscribe for and purchase, during the Term (as hereinafter defined), up to              (            )
shares (subject to adjustment as hereinafter provided) of the duly authorized, validly issued, fully paid and non-assessable Common Stock of the Issuer, at an exercise price per share equal to the Warrant Price then in effect, subject, however, to
the provisions and upon the terms and conditions hereinafter set forth. Capitalized terms used in this Warrant and not otherwise defined herein shall have the respective meanings specified in Section 9 hereof. 
 1. Term. The term of this Warrant shall commence on August 24, 2007 and shall expire at 5:00 p.m., eastern time, on August 24, 2012
(such period being the “Term”). 
 2. Method of Exercise; Payment; Issuance of New Warrant; Transfer and Exchange.

 (a) Time of Exercise. The purchase rights represented by this Warrant may be exercised in whole or in part at any time during the
Term. 
 (b) Method of Exercise. 
 (i) The Holder hereof may exercise this Warrant, in whole or in part, by the surrender of this Warrant (with the exercise form attached hereto duly executed) at the principal office of the Issuer, and by the payment
to the Issuer of an amount of consideration therefor equal to the Warrant Price in effect on the date of such exercise multiplied by the number of shares of Warrant Stock with respect to which this Warrant is then being exercised, payable at such
Holder’s election (i) by certified or official bank check or by wire transfer to an account designated by the Issuer or (iii) by a combination of the foregoing methods of payment selected by the Holder of this Warrant. 

 (ii) Cashless Exercise. Notwithstanding any provisions herein to the contrary, if
at any time during the Effectiveness Period (as such term is defined in the Registration Rights Agreement, dated as of August 24, 2007, between the Issuer and the original Holder hereof), there is no effective registration statement under the
Securities Act covering the resale of the shares of Common Stock issuable upon exercise hereof, then in lieu of exercising this Warrant by payment of cash, the Holder may exercise this Warrant by a “cashless exercise” and shall receive the
number of shares of Common Stock computed using the following formula: 
  

							
		  	X	  	=	  	 Y - (A)(Y)
           B

				
	Where	  	X	  	=	  	the number of shares of Common Stock to be issued to the Holder;
				
		  	Y	  	=	  	the number of shares of Common Stock purchasable upon exercise of all of the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being
exercised;
				
		  	A	  	=	  	the Warrant Price; and
				
		  	B	  	=	  	the Per Share Market Value of one share of Common Stock.

 (c) Issuance of Stock Certificates. In the event of any exercise of the rights represented
by this Warrant in accordance with and subject to the terms and conditions hereof, (i) certificates for the shares of Warrant Stock so purchased shall be dated the date of such exercise and delivered to the Holder hereof within a reasonable
time, not exceeding three (3) Trading Days after such exercise or, at the request of the Holder (provided that a registration statement under the Securities Act providing for the resale of the Warrant Stock is then in effect), issued and
delivered to the Depository Trust Company (“DTC”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) within a reasonable time, not exceeding three (3) Trading Days
after such exercise, and the Holder hereof shall be deemed for all purposes to be the holder of the shares of Warrant Stock so purchased as of the date of such exercise and (ii) unless this Warrant has expired, a new Warrant representing the
number of shares of Warrant Stock, if any, with respect to which this Warrant shall not then have been exercised (less any amount thereof which shall have been canceled in payment or partial payment of the Warrant Price as hereinabove provided)
shall also be issued to the Holder hereof at the Issuer’s expense within such time. 
 (d) Transferability of Warrant. Subject to
Section 2(f), this Warrant may be transferred by a Holder without the consent of the Issuer. If transferred pursuant to this paragraph and subject to the provisions Section 2(f), this Warrant may be transferred on the books of the Issuer
by the Holder hereof in person or by duly authorized attorney, upon surrender of this Warrant at the principal office of the Issuer, properly endorsed (by the Holder executing an assignment in the form attached hereto) and upon payment of any
necessary transfer tax or other governmental charge imposed upon such transfer. This Warrant is exchangeable at the principal 

  

 -2- 

 
office of the Issuer for Warrants for the purchase of the same aggregate number of shares of Warrant Stock, each new Warrant to represent the right to
purchase such number of shares of Warrant Stock as the Holder hereof shall designate at the time of such exchange. All Warrants issued on transfers or exchanges shall be dated the Original Issue Date and shall be identical with this Warrant except
as to the number of shares of Warrant Stock issuable pursuant hereto. 
 (e) Continuing Rights of Holder. The Issuer will, at the time
of or at any time after each exercise of this Warrant, upon the request of the Holder hereof, acknowledge in writing the extent, if any, of its continuing obligation to afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant, provided that if any such Holder shall fail to make any such request, the failure shall not affect the continuing obligation of the Issuer to afford such rights to
such Holder. 
 (f) Compliance with Securities Laws. 
 (i) The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant or the shares of Warrant Stock to be issued upon
exercise hereof are being acquired solely for the Holder’s own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Warrant Stock to
be issued upon exercise hereof except pursuant to an effective registration statement, or an exemption from registration, under the Securities Act and any applicable state securities laws. 
 (ii) Except as provided in paragraph (iii) below, this Warrant and all certificates representing shares of Warrant Stock issued upon
exercise hereof shall be stamped or imprinted with a legend in substantially the following form: 
 THIS WARRANT AND THE SHARES OF COMMON
STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER
THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR FLO CORPORATION SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS
IS NOT REQUIRED. 
 (iii) The restrictions imposed by this subsection (f) upon the transfer of this Warrant or the shares
of Warrant Stock to be purchased upon exercise hereof shall terminate (A) when such securities shall have been resold pursuant to an effective registration statement under the Securities Act, (B) upon the Issuer’s receipt of an
opinion of counsel, in form and substance reasonably satisfactory to the Issuer, addressed to the Issuer to the effect that such restrictions are no longer required to ensure compliance with the Securities Act and state securities laws or
(C) upon the Issuer’s 

  

 -3- 

 
receipt of other evidence reasonably satisfactory to the Issuer that such registration and qualification under the Securities Act and state securities laws
are not required. Whenever such restrictions shall cease and terminate as to any such securities, the Holder thereof shall be entitled to receive from the Issuer (or its transfer agent and registrar), without expense (other than applicable transfer
taxes, if any), new Warrants (or, in the case of shares of Warrant Stock, new stock certificates) of like tenor not bearing the applicable legend required by paragraph (ii) above relating to the Securities Act and state securities laws.

 3. Stock Fully Paid; Reservation and Listing of Shares; Covenants. 
 (a) Stock Fully Paid. The Issuer represents, warrants, covenants and agrees that all shares of Warrant Stock which may be issued upon the exercise
of this Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by or through Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at all times have authorized and reserved for the purpose of the issue upon exercise of this Warrant a sufficient number of shares of Common Stock to provide for the
exercise of this Warrant. 
 (b) Reservation. If any shares of Common Stock required to be reserved for issuance upon exercise of this
Warrant or as otherwise provided hereunder require registration or qualification with any governmental authority under any federal or state law before such shares may be so issued, the Issuer will in good faith use its reasonable best efforts as
expeditiously as possible at its expense to cause such shares to be duly registered or qualified. If the Issuer shall list any shares of Common Stock on any securities exchange or market it will, at its expense, list thereon, maintain and increase
when necessary such listing, of, all shares of Warrant Stock from time to time issued upon exercise of this Warrant or as otherwise provided hereunder (provided that such Warrant Stock has been registered pursuant to a registration statement under
the Securities Act then in effect), and, to the extent permissible under the applicable securities exchange rules, all unissued shares of Warrant Stock which are at any time issuable hereunder, so long as any shares of Common Stock shall be so
listed. The Issuer will also so list on each securities exchange or market, and will maintain such listing of, any other securities which the Holder of this Warrant shall be entitled to receive upon the exercise of this Warrant if at the time any
securities of the same class shall be listed on such securities exchange or market by the Issuer. 
 (c) Covenants. The Issuer shall
not by any action including, without limitation, amending the Certificate of Incorporation or the by-laws of the Issuer, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other
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 the Holder hereof against impairment. Without limiting the generality of the foregoing, the Issuer will (i) not permit the par value, if any, of its Common Stock to exceed the then effective Warrant Price,
(ii) not amend or modify any provision of the Certificate of Incorporation or by-laws of the Issuer in any manner that would adversely affect the rights of the Holders of the Warrants, (iii) take all such action as may be reasonably
necessary in order that the Issuer may validly and 

  

 -4- 

 
legally issue fully paid and nonassessable shares of Common Stock, free and clear of any liens, claims, encumbrances and restrictions (other than as provided
herein or under applicable securities laws) upon the exercise of this Warrant, and (iv) use its reasonable best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may
be reasonably necessary to enable the Issuer to perform its obligations under this Warrant. 
 (d) Loss, Theft, Destruction of
Warrants. Upon receipt of evidence satisfactory to the Issuer of the ownership of and the loss, theft, destruction or mutilation of any Warrant and, in the case of any such loss, theft or destruction, upon receipt of indemnity or security
satisfactory to the Issuer or, in the case of any such mutilation, upon surrender and cancellation of such Warrant, the Issuer will make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and
representing the right to purchase the same number of shares of Common Stock. 
 4. Adjustment of Warrant Price. The price at which
shares of Common Stock for which this Warrant is exercisable may be purchased upon exercise of this Warrant shall be subject to adjustment from time to time as set forth in this Section 4. The Issuer shall give the Holder notice of any event
described below which requires an adjustment pursuant to this Section 4 in accordance with Section 5. 
 (a) Recapitalization,
Reorganization, Reclassification, Consolidation, Merger or Sale. 
 (i) In case the Issuer after the Original Issue Date
shall do any of the following (each, a “Triggering Event”): (a) consolidate with or merge into any other Person and the Issuer shall not be the continuing or surviving corporation of such consolidation or merger, or
(b) permit any other Person to consolidate with or merge into the Issuer and the Issuer shall be the continuing or surviving Person but, in connection with such consolidation or merger, any Capital Stock of the Issuer shall be changed into or
exchanged for securities of any other Person or cash or any other property, or (c) transfer all or substantially all of its properties or assets to any other Person, or (d) effect a capital reorganization or reclassification of its Capital
Stock, then, and in the case of each such Triggering Event, proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the Holder of this Warrant shall be entitled upon the exercise hereof at any
time after the consummation of such Triggering Event, to the extent this Warrant is not exercised prior to such Triggering Event, to receive at the Warrant Price in effect at the time immediately prior to the consummation of such Triggering Event in
lieu of the Common Stock issuable upon such exercise of this Warrant prior to such Triggering Event, the securities, cash and property to which such Holder would have been entitled upon the consummation of such Triggering Event if such Holder had
exercised the rights represented by this Warrant immediately prior thereto, subject to adjustments (subsequent to such corporate action) as nearly equivalent as possible to the adjustments provided for elsewhere in this Section 4. 

(ii) Notwithstanding anything contained in this Warrant to the contrary, a Triggering Event shall not be deemed to have occurred if,
prior to the consummation thereof, each Person (other than the Issuer) which may be required to deliver any Securities, cash or property upon the exercise of this Warrant as provided herein shall 

  

 -5- 

 
assume, by written instrument delivered to, and reasonably satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer under this
Warrant (and if the Issuer shall survive the consummation of such Triggering Event, such assumption shall be in addition to, and shall not release the Issuer from, any continuing obligations of the Issuer under this Warrant) and (B) the
obligation to deliver to such Holder such Securities, cash or property as, in accordance with the foregoing provisions of this subsection (a), such Holder shall be entitled to receive, and such Person shall have similarly delivered to such Holder an
opinion of counsel for such Person, which counsel shall be reasonably satisfactory to such Holder, or in the alternative, a written acknowledgement executed by the President or Chief Financial Officer of the Issuer, stating that this Warrant shall
thereafter continue in full force and effect and the terms hereof (including, without limitation, all of the provisions of this subsection (a)) shall be applicable to the Securities, cash or property which such Person may be required to deliver upon
any exercise of this Warrant or the exercise of any rights pursuant hereto. 
 (b) Stock Dividends, Subdivisions and Combinations. If
at any time the Issuer shall: 
 (i) take a record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend payable in, or other distribution of, shares of Common Stock, 
 (ii) subdivide its outstanding shares of
Common Stock into a larger number of shares of Common Stock, or 
 (iii) combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock, 
 then (1) the number of shares of Common Stock for which this Warrant is exercisable immediately after the
occurrence of any such event shall be adjusted to equal the number of shares of Common Stock which a record holder of the same number of shares of Common Stock for which this Warrant is exercisable immediately prior to the occurrence of such event
would own or be entitled to receive after the happening of such event, and (2) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then in effect multiplied by the number of shares of Common Stock for which
this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment. 
 (c) Certain Other Distributions. If at any time the Issuer shall take a record of the holders of its Common Stock for the purpose of entitling
them to receive any dividend or other distribution of: 
 (i) cash (other than a cash dividend payable out of earnings or
earned surplus legally available for the payment of dividends under the laws of the jurisdiction of incorporation of the Issuer), 
 (ii) any evidences of its indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents or Additional Shares of Common Stock), or 
  

 -6- 

 (iii) any warrants or other rights to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or property of any nature whatsoever (other than cash, Common Stock Equivalents or Additional Shares of Common Stock), 
 then (1) the number of shares of Common Stock for which this Warrant is exercisable shall be adjusted to equal the product of the number of shares of Common Stock
for which this Warrant is exercisable immediately prior to such adjustment multiplied by a fraction (A) the numerator of which shall be the Per Share Market Value of Common Stock at the date of taking such record and (B) the denominator of
which shall be such Per Share Market Value minus the amount allocable to one share of Common Stock of any such cash so distributable and of the fair value (as determined in good faith by the Board of Directors of the Issuer) of any and all such
evidences of indebtedness, shares of stock, other securities or property or warrants or other subscription or purchase rights so distributable, and (2) the Warrant Price then in effect shall be adjusted to equal (A) the Warrant Price then
in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment. A reclassification of the Common Stock (other than a change in par value, or from par value to no par value or from no par value to par value) into shares of Common Stock and shares of any other class of stock shall be deemed a
distribution by the Issuer to the holders of its Common Stock of such shares of such other class of stock within the meaning of this Section 4(c) and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of
shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock within the meaning of Section 4(b). 
 (d) Issuance of Additional Shares of Common Stock. 
 (i) In the event the Issuer shall at any time issue any Additional Shares of Common Stock (otherwise than as provided in the foregoing subsections (b) through (c) of this Section 4 and other than
Permitted Issuances) at a price per share less than the Warrant Price then in effect or without consideration, then the Warrant Price upon each such issuance shall be adjusted to that price determined by multiplying the Warrant Price then in effect
by a fraction: 
 (A) the numerator of which shall be equal to the sum of (x) the number of shares of Outstanding Common
Stock immediately prior to the issuance of such Additional Shares of Common Stock plus (y) the number of shares of Common Stock which the aggregate consideration for the total number of such Additional Shares of Common Stock so issued
would purchase at a price per share equal to the Warrant Price then in effect, and 
 (B) the denominator of which shall be
equal to the number of shares of Outstanding Common Stock immediately after the issuance of such Additional Shares of Common Stock. 
 (ii) The provisions of Section 4(d)(i) shall not apply to any issuance of Additional Shares of Common Stock for which an adjustment is provided under Section 4(b) or 4(c). 
  

 -7- 

 (e) Issuance of Warrants or Other Rights. In the event the Company shall (whether directly or by
assumption in a merger in which the Company is the surviving corporation) issue or sell, any warrants or other rights to subscribe for or purchase any Additional Shares of Common Stock or any Convertible Securities, whether or not the rights to
exchange or convert thereunder are immediately exercisable (other than Permitted Issuances), and the price per share for which Common Stock is issuable upon the exercise of such warrants or other rights shall be less than the Warrant Price in effect
immediately prior to the time of such issue or sale, then the Warrant Price shall be adjusted as provided in Section 4(d) on the basis that the maximum number of Additional Shares of Common Stock issuable pursuant to all such warrants or
other rights or necessary to effect the conversion or exchange of all such Convertible Securities shall be deemed to have been issued and outstanding and the Company shall have received all of the consideration payable therefor, if any, as of the
date of the actual issuance of the number of shares for which this Warrant is exercisable and such warrants or other rights. No further adjustments of the Warrant Price shall be made upon the actual issue of such Common Stock or of such Convertible
Securities upon exercise of such warrants or other rights or upon the actual issue of such Common Stock upon such conversion or exchange of such Convertible Securities. 
 (f) Issuance of Convertible Securities. In the event the Company shall (whether directly or by assumption in a merger in which the Company is the surviving corporation) issue or sell any Convertible Securities,
other than pursuant to Permitted Issuances, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange shall be less than the
Warrant Price in effect immediately prior to the time of such issue or sale, then the Warrant Price shall be adjusted as provided in Section 4(d) on the basis that the maximum number of Additional Shares of Common Stock necessary to
effect the conversion or exchange of all such Convertible Securities shall be deemed to have been issued and outstanding and the Company shall have received all of the consideration payable therefor, if any, as of the date of actual issuance of such
Convertible Securities. No adjustment of the Warrant Price shall be made under this Section 4(f) upon the issuance of any Convertible Securities that are issued pursuant to the exercise of any warrants or other subscription or purchase
rights therefor, if any such adjustment shall previously have been made upon the issuance of such warrants or other rights pursuant to Section 4(e). No further adjustments of the Warrant Price shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Convertible Securities and, if any issue or sale of such Convertible Securities is made upon exercise of any warrant or other right to subscribe for or to purchase any such Convertible Securities for
which adjustments of the Warrant Price have been or are to be made pursuant to other provisions of this Section 4, no further adjustments of the Warrant Price shall be made by reason of such issue or sale. 
 (g) Superseding Adjustment. If, at any time after any adjustment of the number of shares of Common Stock for which this Warrant is exercisable and
the Warrant Price then in effect shall have been made pursuant to Section 4(c) as the result of any issuance of warrants, other rights or Common Stock Equivalents, and (i) such warrants or other rights, or the right of conversion or
exchange in such other Common Stock Equivalents, shall expire, and all or a portion of such warrants or other rights, or the right of conversion or exchange with respect to all or a portion of such other Common Stock Equivalents, as the case may be,
shall not have been exercised, or (ii) the consideration per share for which shares of Common Stock are issuable 

  

 -8- 

 
pursuant to such Common Stock Equivalents, shall be increased solely by virtue of provisions therein contained for an automatic increase in such
consideration per share upon the occurrence of a specified date or event, then for each outstanding Warrant such previous adjustment shall be rescinded and annulled and the Additional Shares of Common Stock which were deemed to have been issued by
virtue of the computation made in connection with the adjustment so rescinded and annulled shall no longer be deemed to have been issued by virtue of such computation. Upon the occurrence of an event set forth in this Section 4(g) above, there
shall be a recomputation made of the effect of such Common Stock Equivalents on the basis of: (i) treating the number of Additional Shares of Common Stock or other property, if any, theretofore actually issued or issuable pursuant to the
previous exercise of any such warrants or other rights or any such right of conversion or exchange, as having been issued on the date or dates of any such exercise and for the consideration actually received and receivable therefor, and
(ii) treating any such Common Stock Equivalents which then remain outstanding as having been granted or issued immediately after the time of such increase of the consideration per share for which shares of Common Stock or other property are
issuable under such Common Stock Equivalents; whereupon a new adjustment of the number of shares of Common Stock for which this Warrant is exercisable and the Warrant Price then in effect shall be made, which new adjustment shall supersede the
previous adjustment so rescinded and annulled. 
 (h) Reduction of Warrant Exercise Price by Issuer. If the Issuer at any time while
this Warrant is outstanding shall offer the Holder the opportunity to exercise this Warrant at a price per share less than the applicable Warrant Price (each, a “Special Warrant Offer”), then the Warrant Price then in effect shall
be reduced to the exercise price offered pursuant to the Special Warrant Offer. Notwithstanding anything to the contrary contained in this Warrant, any adjustment of the Warrant Price made pursuant to this paragraph shall not survive the expiration
of a Special Warrant Offer unless the Holder participates in such Special Warrant Offer (to the fullest extent permitted by the Company). 
 (i) Other Provisions applicable to Adjustments under this Section. The following provisions shall be applicable to the making of adjustments of the number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4: 
 (i) When Adjustments to Be Made. The adjustments
required by this Section 4 shall be made whenever and as often as any specified event requiring an adjustment shall occur, except that any adjustment of the number of shares of Common Stock for which this Warrant is exercisable that would
otherwise be required may be postponed (except in the case of a subdivision or combination of shares of the Common Stock, as provided for in Section 4(b)) up to, but not beyond the date of exercise if such adjustment either by itself or with
other adjustments not previously made adds or subtracts less than one percent (1%) of the shares of Common Stock for which this Warrant is exercisable immediately prior to the making of such adjustment. Any adjustment representing a change of
less than such minimum amount (except as aforesaid) which is postponed shall be carried forward and made as soon as such adjustment, together with other adjustments required by this Section 4 and not previously made, would result in a minimum
adjustment or on the date of exercise. For the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on the date of its occurrence. 
  

 -9- 

 (ii) Fractional Interests.
In computing adjustments under this Section 4, fractional interests in Common Stock shall be taken into account to the nearest one one-hundredth (1/100th) of a share. 
 (iii) When Adjustment Not Required. If the Issuer shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive a dividend or distribution or subscription or purchase rights and shall, thereafter and before the distribution to stockholders thereof, legally abandon its plan to pay or deliver such
dividend, distribution, subscription or purchase rights, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled. 

(j) Form of Warrant after Adjustments. The form of this Warrant need not be changed because of any adjustments in the Warrant Price or the
number and kind of Securities purchasable upon the exercise of this Warrant. 
 (k) Escrow of Warrant Stock. If, after any property
becomes distributable pursuant to this Section 4 by reason of the taking of any record of the holders of Common Stock, but prior to the occurrence of the event for which such record is taken, the Holder exercises this Warrant, any shares of
Common Stock issuable upon exercise by reason of such adjustment shall be deemed the last shares of Common Stock for which this Warrant is exercised (notwithstanding any other provision to the contrary herein) and such shares or other property shall
be held in escrow for the Holder by the Issuer to be issued to the Holder upon and to the extent that the event actually takes place, upon payment of the current Warrant Price. Notwithstanding any other provision to the contrary herein, if the event
for which such record was taken fails to occur or is rescinded, then such escrowed shares shall be cancelled by the Issuer and escrowed property returned. 
 5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share Number shall be adjusted pursuant to Section 4 hereof (for purposes of this Section 5, each an “adjustment”), the Issuer
shall cause its Chief Financial Officer to prepare and execute a certificate setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a
description of the basis on which the Board made any determination hereunder), and the Warrant Price and Warrant Share Number after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the Holder of this
Warrant promptly after each adjustment. 
 6. Fractional Shares. No fractional shares of Warrant Stock will be issued in connection
with and exercise hereof. If any fraction of a share of Common Stock would, except for the provisions of this Section, be issuable on the exercise hereof, the Company will (i) round down and issue to the holder only the largest whole number of
shares of Common Stock to which the holder is otherwise entitled if the fraction of a share otherwise issuable is less than one-half, or (2) round up and issue to the holder one additional share of Common Stock in addition to the largest whole
number of shares of Common Stock to which the holder is otherwise entitled, if the fraction of a share of Common Stock otherwise issuable is greater than one-half. The determination as to whether or not any fractional shares are issuable shall be
based upon the total number of shares of Common Stock for which warrants are being exercised at any one time by the holder hereof, not upon each warrant being exercised. 
  

 -10- 

 7. Ownership Cap and Certain Exercise Restrictions. (a) Notwithstanding anything to the
contrary set forth in this Warrant, at no time may a Holder of this Warrant exercise this Warrant if the number of shares of Common Stock to be issued pursuant to such exercise would exceed, when aggregated with all other shares of Common Stock
beneficially owned (as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules thereunder) by such Holder at such time, the number of shares of Common
Stock which would result in such Holder beneficially owning in excess of 4.9% of all of the Outstanding Common Stock at such time; provided, however, that upon the Holder of this Warrant providing the Issuer with sixty-one
(61) days notice (pursuant to Section 13 hereof) (the “Waiver Notice”) that such Holder would like to waive this Section 7(a) with regard to any or all shares of Common Stock issuable upon exercise of this Warrant
(and upon consent of the Issuer, which will not be unreasonably withheld), this Section 7(a) shall be of no force or effect with regard to those shares of Warrant Stock referenced in the Waiver Notice. 
 (b) Notwithstanding anything to the contrary set forth in Section 7 of this Warrant, at no time may the Holder exercise all or a portion of this
Warrant if the number of shares of Common Stock to be issued pursuant to such conversion, when aggregated with all other shares of Common Stock beneficially owned (as determined in accordance with Section 13(d) of the Exchange Act and the rules
thereunder) by the Holder at such time, would result in the Holder beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules thereunder) in excess of 9.9% of all of the Outstanding Common Stock at
such time. 
 (c) In the event that the operation of this Section 7 prevents the Holder from fully exercising this Warrant, such Holder
may elect to receive Series C Convertible Preferred Stock of the Issuer in lieu of shares of Common Stock convertible into the number of shares of Common Stock that would have been delivered to such Holder but for the limitations set forth in this
Section 7. The foregoing sentence shall not preclude the Holder from waiving at any time its rights to limit its ownership to 4.9% of all of the Outstanding Common Stock at such time in accordance with Section 7(a) hereof. “Series C
Convertible Preferred Stock” means a series of non-voting preferred stock of the Issuer with terms such that a holder thereof shall not be deemed a beneficial owner (as determined in accordance with Section 13(d) of the Exchange Act and
the rules thereunder) of the Common Stock issuable upon conversion thereof, and otherwise with terms similar to the Common Stock. 
 8.
Call. Notwithstanding anything herein to the contrary, the Issuer, at its option, may call up to one hundred percent (100%) of this Warrant by providing the Holder of this Warrant written notice pursuant to Section 13 (the
“Call Notice”) if the Per Share Market Value of the Common Stock has been equal to or greater than 200% of the Warrant Price (as may be adjusted for any stock splits or combinations of the Common Stock) for a period of twenty
(20) consecutive Trading Days immediately prior to the date of delivery of the Call Notice; provided that (i) a registration statement under the Securities Act providing for the resale of the Warrant Stock and the Common Stock
issuable upon conversion of the Issuer’s Series A Preferred Stock issued pursuant to the Stock Purchase Agreement is then in effect and (ii) trading in the Common Stock shall not have been suspended by the Securities and Exchange
Commission or any exchange on which it is then listed; provided, further, that a registration statement under the Securities Act providing for the resale of the Warrant Stock and the Common Stock issuable 

  

 -11- 

 
upon conversion of the Issuer’s Series A Preferred Stock issued pursuant to the Stock Purchase Agreement is in effect from the date of delivery of the
Call Notice until the date which is the later of (A) the date the Holder exercises the Warrant pursuant to the Call Notice and (B) the 10th Trading Day after the Holder receives the Call Notice (the “Early Termination Date”). The rights and privileges granted pursuant to this Warrant with respect to the shares of Warrant Stock subject to the Call Notice (the
“Called Warrant Shares”) shall expire on the Early Termination Date if this Warrant is not exercised with respect to such Called Warrant Shares prior to such Early Termination Date. In the event this Warrant is not exercised with
respect to the Called Warrant Shares, the Issuer shall remit to the Holder of this Warrant (1) $0.10 per Called Warrant Share and (2) a new Warrant representing the number of shares of Warrant Stock, if any, which shall not have been
subject to the Call Notice upon the Holder tendering to the Issuer the applicable Warrant certificate.
