 For value received, FLO Corporation, a Delaware corporation (the “Maker”), hereby
promises to pay to the order of                                  (together with

Notes”) to separate purchasers (the “Additional Holders”) in the aggregate principal amount of up to $8,500,000 (inclusive of this Note). 
 All payments under or pursuant to this Note shall be made in United States Dollars in immediately available funds to the Holder at the address of the Holder set forth in the Purchase Agreement (as defined below) or at
such other place as the Holder may designate from time to time in writing to the Maker or by wire transfer of funds to the Holder’s account, instructions for which are attached hereto as Exhibit A. The outstanding principal balance of

 Section 1.2 Interest. Beginning on the issuance date of this Note (the “Issuance

quarter at the option of the Maker in cash or Additional Notes, which shall also each mature on the Maturity Date (the “Ordinary Interest”). Interest shall be computed on the basis of a 360-day year of twelve (12) 30-day months and
shall accrue commencing on the Issuance Date. Furthermore, upon the occurrence of an Event of Default (as defined in Section 2.1 hereof), then to the extent permitted by law, in lieu of the Ordinary Interest, the Maker will pay interest in cash
to the Holder, payable on demand, on the outstanding principal balance of the Note from the date of the Event of Default until such Event of Default is cured at the rate of the lesser of fifteen percent (15%) and the maximum applicable legal
rate per annum.

Sunday or a public holiday under the laws of the State of New York, such payment may be due on the next succeeding business day and such next succeeding day shall be included in the calculation of the amount of accrued interest payable on such date.

 ARTICLE III 
 CONVERSION; ANTIDILUTION;
PREPAYMENT 
 Section 3.1 Conversion. 
 (a) Optional Conversion. At any time on or after the Issuance Date, this Note shall be convertible (in whole or in part), at the option of the Holder (the “Conversion Option”), into such number
of fully paid and non-assessable shares of Common Stock (the “Conversion Rate”) as is determined by dividing (x) that portion of the outstanding principal balance plus any accrued but unpaid interest under this Note as of such
date that the Holder elects to convert by (y) the Conversion Price (as defined in Section 3.2(a) hereof) then in effect on the date on which the Holder faxes a notice of conversion (the “Conversion Notice”), duly executed,
to the Maker (facsimile number (425) 278-1299, Attn.: Chief Executive Officer, with a copy to facsimile number 206-839-4801, Attn.: W. Michael Hutchings, Esq.) (the “Optional Conversion Date”), provided, however, that the
Conversion Price shall be subject to adjustment as described in Section 3.6 below. The Holder shall deliver this Note to the Maker at the address designated in the Purchase Agreement at such time that this Note is fully converted. With respect
to partial conversions of this Note, the Maker shall keep written records of the amount of this Note converted as of each Conversion Date. 
 (b) Mandatory Conversion. On the Mandatory Conversion Date (as defined below), this Note shall automatically and without any action on the part of the Holder, convert into such number of fully paid and non-assessable shares of Common
Stock as is determined by dividing (x) that portion of the outstanding principal balance plus any accrued but unpaid interest under this Note as of the Mandatory Conversion Date by (y) the Conversion Price then in effect on the Mandatory
Conversion Date, provided, however, that the Conversion Price shall be subject to adjustment as described in Section 3.6 below. As used herein, “Mandatory Conversion Date” shall be the first date on or after
                , 2008 that the Closing Bid Price (as defined 

  

 -4- 

 
below) of the Common Stock has exceeded $3.00 (as adjusted for stock splits, stock dividends, combinations and similar transactions) for twenty
(20) consecutive trading days. The Mandatory Conversion Date and the Voluntary Conversion Date collectively are referred to in this Note as the “Conversion Date.” Notwithstanding the foregoing to the contrary, the Note shall
automatically convert pursuant to this Section 3.1(b) only if (1) the Conversion Shares are eligible to be sold under Rule 144 of the Securities Act (2) trading in the Common Stock shall not have been suspended by the Securities and
Exchange Commission or the OTC Bulletin Board (or other exchange or market on which the Common Stock is trading), and (3) the Maker is in material compliance with the terms and conditions of this Note and the other Transaction Documents. The
term “Closing Bid Price” shall mean, on any particular date, the last closing bid price per share of the Common Stock on such date quoted on the OTC Bulletin Board or any registered national stock exchange on which the Common Stock is then
listed, or if there is no such price on such date, then the last closing bid price on such exchange or quotation system on the date nearest preceding such date. 
 Section 3.2 Conversion Price. 
 (a) The term “Conversion Price” shall mean
$0.80, subject to adjustment under Section 3.6 hereof. 
 Section 3.3 Mechanics of Conversion. 
 (a) Not later than three (3) Trading Days after any Conversion Date, the Maker or its designated transfer agent, as applicable, shall issue and
deliver to the Depository Trust Company (“DTC”) account on the Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) as specified in the Conversion Notice, registered in the name of the
Holder or its designee, such number of shares of Common Stock to which the Holder shall be entitled. In the alternative, not later than three (3) Trading Days after any Conversion Date, the Maker shall deliver to the applicable Holder by
express courier a certificate or certificates which shall be free of restrictive legends and trading restrictions (other than those required by Section 5.1 of the Purchase Agreement) representing the number of shares of Common Stock being
acquired upon the conversion of this Note (the “Delivery Date”). If in the case of any Conversion Notice such certificate or certificates are not delivered to or as directed by the applicable Holder by the Delivery Date, the Holder
shall be entitled by written notice to the Maker at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, in which event the Maker shall immediately return this Note tendered for conversion,
whereupon the Maker and the Holder shall each be restored to their respective positions immediately prior to the delivery of such notice of revocation, except that any amounts described in Sections 3.3(b) and (c) shall be payable through the
date notice of rescission is given to the Maker. 
 (b) The Maker understands that a delay in the delivery of the shares of Common Stock upon
conversion of this Note beyond the Delivery Date could result in economic loss to the Holder. Subject to Section 3.3(d) hereof, if the Maker fails to deliver to the Holder such shares via DWAC or a certificate or certificates pursuant to this
Section hereunder by the Delivery Date, the Maker shall pay to such Holder, in cash, an amount per Trading Day for each Trading Day until such shares are delivered via DWAC or certificates are delivered, together with interest on such amount at a
rate of 10% per annum, accruing until such amount and any 

  

 -5- 

 
accrued interest thereon is paid in full, equal to the greater of (A) (i) 1% of the aggregate principal amount of the Note requested to be
converted for the first five (5) Trading Days after the Delivery Date and (ii) 2% of the aggregate principal amount of the Note requested to be converted for each Trading Day thereafter and (B) $2,000 per day (which amount shall be
paid as liquidated damages and not as a penalty). Except as set forth in Sections 3(c) and 3(d), the remedy provided by this Section 3.3(b) is exclusive and Holder shall have no other right to pursue any remedies available to it at law or
in equity (including, without limitation, a decree of specific performance and/or injunctive relief) arising out of the same occurrence or series of related occurrences that gave rise to this remedy. Notwithstanding anything to the contrary
contained herein, the Holder shall be entitled to withdraw a Conversion Notice, and upon such withdrawal the Maker shall only be obligated to pay the liquidated damages accrued in accordance with this Section 3.3(b) through the date the
Conversion Notice is withdrawn. 
 (c) Subject to Section 3.3(d) hereof, if the Maker fails to cause its transfer agent to transmit to
the Holder a certificate or certificates representing the shares of Common Stock issuable upon conversion of this Note on or before the Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the shares of Common Stock issuable upon conversion of this Note which the Holder anticipated receiving upon such exercise (a
“Buy-In”), then the Maker shall (1) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased
exceeds (y) the amount obtained by multiplying (A) the number of shares of Common Stock issuable upon conversion of this Note that the Maker was required to deliver to the Holder in connection with the conversion at issue times
(B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Note and equivalent number of shares of Common Stock for which such
conversion was not honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Maker timely complied with its conversion and delivery obligations hereunder. For example, if the Holder purchases Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the
immediately preceding sentence the Maker shall be required to pay the Holder $1,000. The Holder shall provide the Maker written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and
other evidence reasonably requested by the Maker. The remedy provided by this Section 3.3(c) is exclusive and Holder shall have no other right to pursue any remedies available to it at law or in equity (including, without limitation, a decree
of specific performance and/or injunctive relief) arising out of the same occurrence or series of related occurrences that gave rise to this remedy. 
 (d) Notwithstanding the foregoing, the remedies provided by Sections 3.3(b) and (c) shall be exclusive of each other and shall not both be available with respect to any single occurrence or series of related
occurrences. If the remedies provided by both Sections 3.3(b) and (c) would otherwise be available with respect to an occurrence or series of related occurrences, then Holder, in its sole discretion, must elect which one shall apply.
Notwithstanding the foregoing, in the event that the Holder is an Insider Purchaser, then subsections (b) and (c) of this Section 3.3 shall not apply and shall have no force or effect. An “Insider Purchaser” means a Holder
who is a director or executive officer of the Maker.

 Section 3.4 Ownership Cap and Certain Conversion Restrictions. 
 (a) Notwithstanding anything to the contrary set forth in Section 3 of this Note, but subject to Section 3.4(c) hereof, at no time may the
Holder convert all or a portion of this Note if the number of shares of Common Stock to be issued pursuant to such conversion 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 the Holder at such time, the number of shares of Common Stock which would result in the Holder beneficially owning (as
determined in accordance with Section 13(d) of the Exchange Act and the rules thereunder) more than 4.9% of all of the Common Stock outstanding at such time; provided, however, that upon the Holder providing the Maker with
sixty-one (61) days notice (pursuant to Section 4.1 hereof) (the “Waiver Notice”) that the Holder would like to waive this Section 3.4(a) with regard to any or all shares of Common Stock issuable upon conversion of
this Note, this Section 3.4(a) will be of no force or effect with regard to all or a portion of the Note referenced in the Waiver Notice. 
 (b) Notwithstanding anything to the contrary set forth in Section 3 of this Note, but subject to Section 3.4(c) hereof, at no time may the Holder convert all or a portion of this Note 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 the then issued and outstanding shares of Common Stock outstanding at such time. 
 (c) In the event the Holder is unable to fully convert this Note in connection with a conversion election following the delivery of a Maker’s
Prepayment Notice pursuant to Section 3.7(k) hereof due to the restrictions set forth in this Section 3.4, such holder may elect to receive, in lieu of shares of Common Stock, Series C Convertible Preferred Stock of the Company 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 3.4(a). The foregoing sentence shall not preclude the Holder from providing a Waiver Notice. In the event
the Holder is unable to fully convert this Note in connection with a mandatory conversion pursuant to Section 3.1(b) hereof, such holder shall receive, in lieu of shares of Common Stock, Series C Convertible Preferred Stock of the Company
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 3.4(a). “Series C Convertible Preferred Stock” means a series of non-voting
preferred stock of the Maker 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. Any determinations as to whether the Holder is unable to fully convert this Note as a result of the provisions of this Section 3.4 shall be in the sole discretion of the Holder;
provided, however, that in the absence of a written notice of such a determination delivered by the Holder to the Maker prior to any event requiring such a determination, the Maker may make such determination its sole discretion and
shall have no liability to Holder for any errors in such determination. 
  

 -7- 

 Section 3.5 Intentionally Omitted. 
 Section 3.6 Adjustment of Conversion Price. 
 (a) The Conversion Price shall be subject to adjustment from time to time as follows: 
 (i)
Adjustments for Stock Splits and Combinations. If the Maker shall at any time or from time to time after the Issuance Date, effect a stock split of the outstanding Common Stock, the applicable Conversion Price in effect immediately prior to
the stock split shall be proportionately decreased. If the Maker shall at any time or from time to time after the Issuance Date, combine the outstanding shares of Common Stock, the applicable Conversion Price in effect immediately prior to the
combination shall be proportionately increased. Any adjustments under this Section 3.6(a)(i) shall be effective at the close of business on the date the stock split or combination occurs. 
 (ii) Adjustments for Certain Dividends and Distributions. If the Maker shall at any time or from time to time after the Issuance
Date, make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in shares of Common Stock, then, and in each event, the applicable Conversion Price in effect
immediately prior to such event shall be decreased as of the time of such issuance or, in the event such record date shall have been fixed, as of the close of business on such record date, by multiplying, the applicable Conversion Price then in
effect by a fraction: 
 (1) the numerator of which shall be the total number of shares of Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such record date; and 
 (2) the denominator of
which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such
dividend or distribution; 
 provided, however, that if such record date shall have been fixed and such dividend or other
distribution is not fully paid or if such dividend or other distribution is not fully made on the date fixed therefor, the Conversion Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or
distributions. 
 (iii) Adjustment for Other Dividends and Distributions. If the Maker shall at any time or from time
to time after the Issuance Date, make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in other than shares of Common Stock, then, and in each event, an
appropriate revision to the applicable Conversion Price shall be made and provision shall be made (by adjustments of the Conversion Price or otherwise) so that the holders of this Note shall receive upon conversions thereof, in addition to the
number of shares of Common Stock 

  

 -8- 

 
receivable thereon, the number of securities of the Maker which they would have received had this Note been converted into Common Stock on the date of such
event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained such securities (together with any distributions payable thereon during such period), giving application to all adjustments called
for during such period under this Section 3.6(a)(iii) with respect to the rights of the holders of this Note and the Additional Notes; provided, however, that if such record date shall have been fixed and such dividend is not
fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions. 
 (iv) Adjustments for Reclassification, Exchange or Substitution. If the Common Stock issuable upon conversion of this Note at any
time or from time to time after the Issuance Date shall be changed to the same or different number of shares of any class or classes of stock, whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or
combination of shares or stock dividends provided for in Sections 3.6(a)(i), (ii) and (iii), or a reorganization, merger, consolidation, or sale of assets provided for in Section 3.6(a)(v)), then, and in each event, an appropriate revision
to the Conversion Price shall be made and provisions shall be made (by adjustments of the Conversion Price or otherwise) so that the Holder shall have the right thereafter to convert this Note into the kind and amount of shares of stock and other
securities receivable upon reclassification, exchange, substitution or other change, by holders of the number of shares of Common Stock into which such Note might have been converted immediately prior to such reclassification, exchange, substitution
or other change, all subject to further adjustment as provided herein. 
 (v) Adjustments for Reorganization, Merger,
Consolidation or Sales of Assets. If at any time or from time to time after the Issuance Date there shall be a capital reorganization of the Maker (other than by way of a stock split or combination of shares or stock dividends or distributions
provided for in Section 3.6(a)(i), (ii) and (iii), or a reclassification, exchange or substitution of shares provided for in Section 3.6(a)(iv)), or a merger or consolidation of the Maker with or into another corporation where the
holders of outstanding voting securities prior to such merger or consolidation do not own over fifty percent (50%) of the outstanding voting securities of the merged or consolidated entity immediately after such merger or consolidation, or the
sale of all or substantially all of the Maker’s properties or assets to any other person (an “Organic Change”), then as a part of such Organic Change, (A) if the surviving entity in any such Organic Change is a public
company whose common stock is registered pursuant to the Exchange Act of 1934 and its common stock is listed or quoted on a national securities exchange, a national automated quotation system or the OTC Bulletin Board, an appropriate revision to the
Conversion Price shall be made and provision shall be made (by adjustments of the Conversion Price or otherwise) so that the Holder shall have the right thereafter to convert such Note into the kind and amount of shares of stock and other securities
or property of the Maker or any successor corporation resulting from Organic Change, and (B) if the surviving entity in any such Organic Change is not a public company whose common stock is registered pursuant to the Exchange Act or its common
stock is not listed or quoted on a national securities exchange, a national automated quotation system or the OTC Bulletin Board, the Holder shall have the right to demand prepayment pursuant to Section 3.7(b) hereof. In any such case,
appropriate adjustment shall be made in the application of the provisions of this Section 3.6(a)(v) with respect to the rights of the Holder after the Organic Change to the end that the 

  

 -9- 

 
provisions of this Section 3.6(a)(v) (including any adjustment in the applicable Conversion Price then in effect and the number of shares of stock or
other securities deliverable upon conversion of this Note and the Additional Notes) shall be applied after that event in as nearly an equivalent manner as may be practicable. 
 (vi) Adjustments for Issuance of Additional Shares of Common Stock.  
 (1) In the event the Maker, shall, at any time, from time to time, issue or sell any additional shares of Common Stock (otherwise than as
provided in the foregoing subsections (i) through (v) of this Section 3.6(a) or pursuant to Common Stock Equivalents (hereafter defined) granted or issued prior to the Issuance Date) (“Additional Shares of Common
Stock”), at a price per share less than the Conversion Price then in effect or without consideration, then the Conversion Price upon each such issuance shall be reduced to a price equal to the per share price paid for such additional shares
of Common Stock; provided, however, that, notwithstanding the foregoing, if, subsequent to the Issuance Date and prior to such issuance and sale, the Maker shall have completed an equity or equity-linked financing with gross proceeds
in an amount of at least $10 million at a price of at least $0.80 per share, then the Conversion Price upon each such issuance shall be adjusted to that price (rounded to the nearest cent) determined by multiplying each of the Conversion 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
Common Stock outstanding immediately prior to the issuance of such Additional Shares of Common Stock plus (y) the number of shares of Common Stock (rounded to the nearest whole share) 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 Conversion Price then in effect, and 
 (B) the denominator of which shall be equal to the number of shares of Common Stock outstanding immediately after the issuance of such Additional Shares of Common Stock. 
 (2) The provisions of paragraph (1) of Section 3.6(a)(vi) shall not apply to any issuance of Additional Shares of Common Stock
for which an adjustment is provided under Section 3.6(a)(vii). No adjustment of the Conversion Price shall be made under paragraph (1) of Section 3.6(a)(vi) upon the issuance of any Additional Shares of Common Stock which are issued
pursuant to the exercise of any Common Stock Equivalents, if any such adjustment shall previously have been made upon the issuance of such Common Stock Equivalents pursuant to Section 3.6(a)(vii). 
 (vii) Issuance of Common Stock Equivalents. If the Maker, at any time after the Issuance Date, shall issue any securities
convertible into or exchangeable for, directly or indirectly, Common Stock (“Convertible Securities”), other than the Promissory Notes, or any rights or warrants or options to purchase any such Common Stock or Convertible
Securities, other than those issued in connection with the issuance of the Note and the Additional Notes (collectively, the “Common Stock Equivalents”), and the aggregate of the price per share for which Additional Shares of Common
Stock may be issuable thereafter pursuant to such Common Stock Equivalent, plus the consideration received by the Maker for issuance of such Common 

  

 -10- 

 
Stock Equivalent divided by the number of shares of Common Stock issuable pursuant to such Common Stock Equivalent (the “Aggregate Per Common Share
Price”) shall be less than the applicable Conversion Price then in effect, or if, after the Issuance Date, the price per share for which Additional Shares of Common Stock may be issuable thereafter pursuant to any Common Stock Equivalent is
amended or adjusted, and such price as so amended shall make the Aggregate Per Share Common Price with respect to such Common Stock Equivalent be less than the applicable Conversion Price in effect at the time of such amendment or adjustment, then
the Conversion Price upon each such issuance or amendment shall be reduced to a price equal to the Aggregate Per Common Share Price; provided, however, that, notwithstanding the foregoing, if, subsequent to the Issuance Date and prior
to such issuance or adjustment, the Maker shall have completed an equity or equity-linked financing with gross proceeds in an amount of at least $10 million at a price of at least $0.80 per share, then the applicable Conversion Price upon each
such issuance or amendment shall be adjusted as provided in the first sentence of subsection (vi) of this Section 3.6(a) on the basis that (1) the maximum number of Additional Shares of Common Stock immediately issuable pursuant to
all such Common Stock Equivalents shall be deemed to have been issued (whether or not such Common Stock Equivalents are actually then exercisable, convertible or exchangeable in whole or in part) as of the earlier of (A) the date on which the
Maker shall enter into a firm contract for the issuance of such Common Stock Equivalent, or (B) the date of actual issuance of such Common Stock Equivalent. No adjustment of the applicable Conversion Price shall be made under this subsection
(vii) upon the issuance of any Convertible Security which is issued pursuant to the exercise of any warrants or other subscription or purchase rights therefor, if any adjustment shall previously have been made to the exercise price of such
warrants then in effect upon the issuance of such warrants or other rights pursuant to this subsection (vii). No adjustment shall be made to the Conversion Price upon the issuance of Common Stock pursuant to the exercise, conversion or exchange of
any Convertible Security or Common Stock Equivalent where an adjustment to the Conversion Price was made as a result of the issuance or purchase of such Convertible Security or Common Stock Equivalent. 
 (viii) Consideration for Stock. In case any shares of Common Stock or any Common Stock Equivalents shall be issued or sold:

 (1) in connection with any merger or consolidation in which the Maker is the surviving corporation (other than any
consolidation or merger in which the previously outstanding shares of Common Stock of the Maker shall be changed to or exchanged for the stock or other securities of another corporation), the amount of consideration therefor shall be deemed to be
the fair value, as determined reasonably and in good faith by the Board of Directors of the Maker, of such portion of the assets and business of the nonsurviving corporation as such Board may determine to be attributable to such shares of Common
Stock, Convertible Securities, rights or warrants or options, as the case may be; or 
 (2) in the event of any consolidation
or merger of the Maker in which the Maker is not the surviving corporation or in which the previously outstanding shares of Common Stock of the Maker shall be changed into or exchanged for the stock or other securities of another corporation, or in
the event of any sale of all or substantially all of the assets of the Maker for stock or other securities of any corporation, the Maker shall be deemed to have issued a number of shares of its Common Stock for stock or securities or other property
of the other corporation computed on the basis of the actual exchange ratio on which the transaction 

  

 -11- 

 
was predicated, and for a consideration equal to the fair market value on the date of such transaction of all such stock or securities or other property of
the other corporation. If any such calculation results in adjustment of the applicable Conversion Price, or the number of shares of Common Stock issuable upon conversion of the Notes, the determination of the applicable Conversion Price or the
number of shares of Common Stock issuable upon conversion of the Notes immediately prior to such merger, consolidation or sale, shall be made after giving effect to such adjustment of the number of shares of Common Stock issuable upon conversion of
the Notes. In the event Common Stock is issued with other shares or securities or other assets of the Maker for consideration which covers both, the consideration computed as provided in this Section 3.6(viii) shall be allocated among such
securities and assets as determined in good faith by the Board of Directors of the Maker. 
 (ix) Market Reset. On
            , 2009 (the “Reset Date”), if the VWAP (as defined below) for the twenty (20) Trading Days preceding the Reset Date (the “20-Day VWAP Reset
Price”) is less than the then applicable Conversion Price, then the Conversion Price shall, as of the Reset Date, be reduced to an amount equal to the greater of (a) the 20-Day VWAP Reset Price or (b) $0.50.
“VWAP” means, for any date, (i) the daily volume weighted average price of the Common Stock for such date on the OTC Bulletin Board as reported by Bloomberg Financial L.P. (based on a Trading Day from 9:30 a.m. Eastern Time to
4:02 p.m. Eastern Time); (ii) if the Common Stock is not then listed or quoted on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by the Pink Sheets, LLC (or a similar
organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or (iii) in all other cases, the fair market value of a share of Common Stock as determined in good
faith by the Board of Directors. 
 (b) Record Date. In case the Maker shall take record of the holders of its Common Stock for the
purpose of entitling them to subscribe for or purchase Common Stock or Convertible Securities, then the date of the issue or sale of the shares of Common Stock shall be deemed to be such record date. 
 (c) Certain Issues Excepted. Anything herein to the contrary notwithstanding, the Maker shall not be required to make any adjustment to the
Conversion Price in connection with: (i) securities issued (other than for cash) in connection with a merger, acquisition, or consolidation; (ii) securities issued or issuable pursuant to the conversion or exercise of convertible or
exercisable securities issued or outstanding on or prior to the date hereof (so long as the conversion or exercise price in such securities are not amended, except in connection with the issuance of the Promissory Notes and Warrants, to lower such
price and/or adversely affect the Holders), pursuant to the conversion of the Series C Convertible Preferred Stock, or in connection with the issuance of the Promissory Notes (including, without limitation, pursuant to the Purchase Agreement or that
certain Exchange Agreement, dated as of             , 2008, by and among the Maker and the holders signatory thereto (the “Exchange Agreement”), or otherwise in connection
with the conversion of Maker’s Series A Preferred Stock); (iii) securities convertible into Common Stock issued in lieu of cash interest payments to holders of the Maker’s securities entitled to interest; (iv) securities issued
in connection with bona fide strategic collaborations, development agreements or licensing transactions approved by the Board; (v) securities issued to financial institutions or lessors in connection with commercial credit 

  

 -12- 

 
arrangements, equipment financings or similar transactions approved by the Maker’s board of directors; (vi) securities issued or issuable pursuant
to any Maker stock option, stock purchase or other equity incentive plan or agreement approved by the Maker’s board of directors; (vii) any securities issued to any placement agent and/or its designees in connection with any offering or
financing of the Maker; (viii) subject to the other provisions of this Section 3.6, securities issued pursuant to any dividends or other distributions on the Maker’s securities, any subdivision of outstanding securities into a greater
number of such securities, or any combination of outstanding securities into a smaller number of such securities; (ix) securities issued pursuant to a bona fide firm underwritten public offering of the Maker’s securities;
(x) securities issuable as a result of the application of similar antidilution provisions in respect of any other securities; (xi) such additional securities as are designated in writing as not requiring any adjustment to the Conversion
Price by holders of a majority of the then aggregate outstanding principal amount of this Note taken together with the Additional Notes; and (xii) the issuance of any securities by way of dividend or other distribution, or upon the exercise or
conversion of, any securities described in clauses (i) through (xi) above. For purposes of this Note, (A) “Promissory Notes” shall mean collectively, each of the following, as the same may be amended from time to
time: (1) the Note, (2) the Additional Notes, and (3) any Additional Notes issued from time to time as interest on the outstanding principal balance of the foregoing promissory notes; and (B) “Warrants” shall
mean, collectively, each of the following, as the same may be amended from time to time: (A) the warrants to purchase shares of Common Stock issued in connection with the issuance of the Note and the Additional Notes; and (B) the warrants
to purchase shares of Common Stock issued and outstanding on or prior to the date hereof. 
 (d) No Impairment. The Maker shall not,
by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed hereunder by the Maker, but will at all times in good faith, assist in the carrying out of all the provisions of this Section 3.6 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the Holder against impairment. In the event a Holder shall elect to convert any Notes as provided herein, the Maker cannot refuse conversion based on any claim that such Holder or anyone
associated or affiliated with such Holder has been engaged in any violation of law, violation of an agreement to which such Holder is a party or for any reason whatsoever, unless an injunction from a court, or notice, restraining or enjoining
conversion of all or part of said Notes shall have been issued. 
 (e) Certificates as to Adjustments. Upon occurrence of each
adjustment or readjustment of the Conversion Price or number of shares of Common Stock issuable upon conversion of this Note pursuant to this Section 3.6, the Maker at its expense shall promptly compute such adjustment or readjustment in
accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment and readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Maker shall, upon written request of the
Holder, at any time, furnish or cause to be furnished to the Holder a like certificate setting forth such adjustments and readjustments, the applicable Conversion Price in effect at the time, and the number of shares of Common Stock and the amount,
if any, of other securities or property which at the time would be received upon the conversion of this Note. Notwithstanding the foregoing, the Maker shall not be obligated to deliver a certificate unless such certificate would reflect an increase
or decrease of at least one percent (1%) of such adjusted amount. 
  

 -13- 

 (f) Issue Taxes. The Maker shall pay any and all issue and other taxes, excluding federal, state
or local income taxes, that may be payable in respect of any issue or delivery of shares of Common Stock on conversion of this Note pursuant thereto; provided, however, that the Maker shall not be obligated to pay any transfer taxes
resulting from any transfer requested by the Holder in connection with any such conversion. 
 (g) Fractional Shares. No fractional
shares of Common Stock shall be issued upon conversion of this Note. In lieu of any fractional shares to which the Holder would otherwise be entitled, the Maker shall pay cash equal to the product of such fraction multiplied by the average of the
Closing Sale Prices of the Common Stock for the five (5) consecutive Trading Days immediately preceding the Conversion Date. The term “Closing Sale Price” shall mean, on any particular date (i) the last closing sale price
per share of the Common Stock on such date on the OTC Bulletin Board or another registered national stock exchange on which the Common Stock is then listed, or if there is no such price on such date, then the last closing sale price on such exchange
or quotation system on the date nearest preceding such date, or (ii) if the Common Stock is not listed then on the OTC Bulletin Board or any registered national stock exchange, the last trading price for a share of Common Stock in the
over-the-counter market, as reported by the OTC Bulletin Board or in the Pink Sheets or similar organization or agency succeeding to its functions of reporting prices) at the close of business on such date, or (iii) if the Common Stock is not
then reported by the OTC Bulletin Board or the Pink Sheets (or similar organization or agency succeeding to its functions of reporting prices), then the average of the “Pink Sheet” quotes for the relevant conversion period, as determined
in good faith by the Holder, or (iv) if the Common Stock is not then publicly traded the fair market value of a share of Common Stock as determined by the Holder and reasonably acceptable to the Maker. 
 (h) Reservation of Common Stock. The Maker shall at all times when this Note shall be outstanding, reserve and keep available out of its
authorized but unissued Common Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of this Note and all interest accrued thereon; provided that the number of shares of Common Stock so
reserved shall at no time be less than one hundred twenty percent (120%) of the number of shares of Common Stock for which this Note and all interest accrued thereon is at any time convertible. The Maker shall, from time to time exercise all
authority in accordance with applicable law to seek approval by stockholders to increase the authorized number of shares of Common Stock if at any time the unissued number of authorized shares shall not be sufficient to satisfy the Maker’s
obligations under this Section 3.6(h). 
 (i) Regulatory Compliance. If any shares of Common Stock to be reserved for the purpose
of conversion of this Note or any interest accrued thereon require registration or listing with or approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such
shares may be validly issued or delivered upon conversion, the Maker shall, at its sole cost and expense, in good faith and as expeditiously as possible, endeavor to secure such registration, listing or approval, as the case may be.

 Section 3.7 Prepayment. 
 (a) Intentionally Omitted. 
 (b)
Prepayment Option Upon Major Transaction. In lieu of any other rights of the Holder contained herein arising in connection with the occurrence of a Major Transaction, simultaneous with the occurrence of a Major Transaction (as defined below),
the Holder shall have the right, at the Holder’s option, to require the Maker to prepay in cash all or a portion of the Holder’s Notes at a price equal to one hundred ten percent (110%) of the aggregate principal amount of this Note
plus all accrued and unpaid interest (the “Major Transaction Prepayment Price”); provided that the Holder shall have the sole option to request payment of the Major Transaction Prepayment Price in cash or registered
shares of common stock of the acquiror in a Major Transaction so long as such shares are being registered under the Securities Act in connection with the Major Transaction and the acquiror is a public company whose common stock is registered
pursuant to the Exchange Act and whose common stock is listed or quoted on a national securities exchange, national automated quotation system or the OTC Bulletin Board. In the event the Holder is an Insider Purchaser, then the Holder agrees that
prepayment of this Note plus all accrued interest pursuant to this Section 3.7(b) shall be expressly subordinate to the payment in full of any Additional Notes then being prepaid pursuant to Section 3.7(b) of such Additional Notes which
are held by Other Holders which are not Insider Purchasers. 
 (c) Prepayment Option Upon Triggering Event. In addition to all other
rights of the Holder contained herein, after a Triggering Event (as defined below), the Holder shall have the right, at the Holder’s option, to require the Maker to prepay all or a portion of this Note in cash at a price equal to (1) in
the case of any Holder who is an Insider Purchaser, one hundred percent (100%) of the aggregate principal amount of this Note plus all accrued and unpaid interest, or (2) in the case of any Holder who is not an Insider Purchaser, the sum
of (i) the greater of (A) one hundred twenty-five percent (125%) of the aggregate principal amount of this Note and (B) in the event at such time the Holder is unable, due to the Triggering Event, to obtain the benefit of its
conversion rights through the conversion of this Note and resale of the shares of Common Stock issuable upon conversion hereof in accordance with the terms of this Note and the other Transaction Documents, the aggregate principal amount of this
Note, divided by the Conversion Price on (x) the date the Prepayment Price (as defined below) is demanded or otherwise due or (y) the date the Prepayment Price is paid in full, whichever is less, multiplied by the VWAP on (x) the date
the Prepayment Price is demanded or otherwise due, and (y) the date the Prepayment Price is paid in full, whichever is greater, and (ii) all other amounts, costs, expenses and liquidated damages due in respect of this Note and the other
Transaction Documents (the “Triggering Event Prepayment Price,” and, collectively with the Major Transaction Prepayment Price, the “Prepayment Price”). In the event the Holder is an Insider Purchaser, then the
Holder agrees that prepayment of this Note plus all accrued interest pursuant to this Section 3.7(c) shall be expressly subordinate to the payment in full of any Additional Notes then being prepaid pursuant to Section 3.7(c) of such
Additional Notes which are held by Other Holders which are not Insider Purchasers. 
 (d) Intentionally Omitted. 
  

 -15- 

 (e) “Major Transaction.” A “Major Transaction” shall be deemed to have
occurred at such time as any of the following events: 
 (i) the consolidation, merger or other business combination of the
Maker with or into another Person (as defined in Section 4.14 hereof) (other than (A) pursuant to a migratory merger effected solely for the purpose of changing the jurisdiction of incorporation of the Maker or (B) a consolidation,
merger or other business combination in which holders of the Maker’s voting power immediately prior to the transaction continue after the transaction to hold, directly or indirectly, the voting power of the surviving entity or entities
necessary to elect a majority of the members of the board of directors (or their equivalent if other than a corporation) of such entity or entities); or 
 (ii) the sale or transfer of more than fifty percent (50%) of the Maker’s assets (based on the fair market value as determined in good faith by the Maker’s Board of Directors) other than inventory in
the ordinary course of business in one or a series of related transactions. 
 (f) “Triggering Event.” A “Triggering
Event” shall be deemed to have occurred at such time as any of the following events: 
 (i) the Maker’s notice
to any holder of the Notes, including by way of public announcement, at any time, of its inability to comply (including for any of the reasons described in Section 3.8) or its intention not to comply with proper requests for conversion of any
Notes into shares of Common Stock; or 
 (ii) the Maker’s failure to comply with a Conversion Notice tendered in
accordance with the provisions of this Note within ten (10) business days after the receipt by the Maker of the Conversion Notice; or 
 (iii) the Maker deregisters its shares of Common Stock and as a result such shares of Common Stock are no longer publicly tradable; or 
 (iv) the Maker consummates a “going private” transaction and as a result the Common Stock is no longer registered under Sections
12(b) or 12(g) of the Exchange Act. 
 (g) Intentionally Omitted. 
 (h) Mechanics of Prepayment at Option of Holder Upon Major Transaction. No sooner than fifteen (15) days nor later than ten (10) days
prior to the consummation of a Major Transaction, but not prior to the public announcement of such Major Transaction, the Maker shall deliver written notice thereof via facsimile and overnight courier (“Notice of Major Transaction”)
to the Holder of this Note. At any time after receipt of a Notice of Major Transaction (or, in the event a Notice of Major Transaction is not delivered at least ten (10) days prior to a Major Transaction, at any time within ten (10) days
prior to a Major Transaction), any holder of the Notes then outstanding may require the Maker to prepay, effective immediately prior to the consummation of such Major Transaction, all of the holder’s Notes then outstanding by delivering written
notice thereof via facsimile and overnight courier (“Notice of Prepayment 

  

 -16- 

 
at Option of Holder Upon Major Transaction”) to the Maker, which Notice of Prepayment at Option of Holder Upon Major Transaction shall indicate
(i) the principal amount of the Notes that such holder is electing to have prepaid and (ii) the applicable Major Transaction Prepayment Price, as calculated pursuant to Section 3.7(b) above. 
 (i) Mechanics of Prepayment at Option of Holder Upon Triggering Event. Within one (1) business day after the occurrence of a Triggering
Event, the Maker shall deliver written notice thereof via facsimile and overnight courier (“Notice of Triggering Event”) to each holder of the Notes. At any time after the earlier of a holder’s receipt of a Notice of Triggering Event
and such holder becoming aware of a Triggering Event having occurred, any holder of this Note may require the Maker to prepay this Note by delivering written notice thereof via facsimile and overnight courier (“Notice of Prepayment at Option
of Holder Upon Triggering Event”) to the Maker, which Notice of Prepayment at Option of Holder Upon Triggering Event shall indicate (i) the amount of the Note that such holder is electing to have prepaid and (ii) the applicable
Triggering Event Prepayment Price, as calculated pursuant to Section 3.7(c) above. A holder shall only be permitted to require the Maker to prepay the Note pursuant to Section 3.7 hereof for the greater of a period of ten (10) days
after receipt by such holder of a Notice of Triggering Event or for so long as such Triggering Event is continuing. 
 (j) Payment of
Prepayment Price. Each holder that has sent a Notice(s) of Prepayment at Option of Holder Upon Triggering Event or a Notice(s) of Prepayment at Option of Holder Upon Major Transaction shall promptly submit to the Maker such holder’s
certificates representing the Notes that such holder has elected to have prepaid. The Maker shall deliver the applicable Triggering Event Prepayment Price, in the case of a prepayment pursuant to Section 3.7(i), to such holder within five
(5) business days after the Maker’s receipt of a Notice of Prepayment at Option of Holder Upon Triggering Event and, in the case of a prepayment pursuant to Section 3.7(h), the Maker shall deliver the applicable Major Transaction
Prepayment Price immediately prior to the consummation of the Major Transaction; provided that a holder’s original Note shall have been so delivered to the Maker; provided further that if the Maker is unable to prepay all of the Notes to be
prepaid, the Maker shall prepay an amount from each holder of the Notes being prepaid equal to such holder’s pro-rata amount (based on the number of Notes held by such holder relative to the number of Notes outstanding) of all Notes being
prepaid. If the Maker shall fail to prepay all of the Notes submitted for prepayment (other than pursuant to a dispute as to the arithmetic calculation of the Prepayment Price), in addition to any remedy such holder of the Notes may have under this
Note and the Purchase Agreement, the applicable Prepayment Price payable in respect of such Notes not prepaid shall bear interest at the rate of two percent (2%) per month (prorated for partial months) until paid in full. Until the Maker pays
such unpaid applicable Prepayment Price in full to a holder of the Notes submitted for prepayment, such holder shall have the option (the “Void Optional Prepayment Option”) to, in lieu of prepayment, require the Maker to promptly
return to such holder(s) all of the Notes that were submitted for prepayment by such holder(s) under this Section 3.7 and for which the applicable Prepayment Price has not been paid, by sending written notice thereof to the Maker via facsimile
(the “Void Optional Prepayment Notice”). Upon the Maker’s receipt of such Void Optional Prepayment Notice(s) and prior to payment of the full applicable Prepayment Price to such holder, (i) the Notice(s) of Prepayment at
Option of Holder Upon Triggering Event or the Notice(s) of Prepayment at Option of Holder Upon Major Transaction, as the case may be, shall be null and void with respect to those Notes submitted for prepayment and for which the 

  

 -17- 

 
applicable Prepayment Price has not been paid, (ii) the Maker shall immediately return any Notes submitted to the Maker by each holder for prepayment
under this Section 3.7(j) and for which the applicable Prepayment Price has not been paid and (iii) the Conversion Price of such returned Notes shall be adjusted to the Conversion Price as in effect on the date on which the Void Optional
Prepayment Notice(s) is delivered to the Maker; provided that no adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect. A holder’s delivery of a Void Optional Prepayment
Notice and exercise of its rights following such notice shall not affect the Maker’s obligations to make any payments which have accrued prior to the date of such notice. Payments provided for in this Section 3.7 shall have priority to
payments to the Maker’s stockholders in connection with a Major Transaction. 
 (k) Maker Prepayment Option. 
 (i) At any time following
            , 2008, the Maker may prepay in cash all or any portion of the outstanding principal amount of this Note together with all accrued and unpaid interest thereon upon ten
(10) Trading Days prior written notice to the Holder (the “Maker’s Prepayment Notice”) at a price (the “Maker’s Prepayment Price”) equal to (A) one hundred percent (100%) of the aggregate
principal amount of this Note; plus (B) any accrued but unpaid interest outstanding at such time; (C) plus an amount equal to interest at the interest rate as determined in accordance with Section 1.2 hereof on the principal amount of
this Note being prepaid for a period that commences on the date of such prepayment and that terminates on the Maturity Date; provided, however, that if the Holder has delivered a Conversion Notice to the Maker or delivers a Conversion
Notice within such ten (10) Trading Day period following delivery of the Maker’s Prepayment Notice, the principal amount of this Note designated to be converted may not be prepaid by the Maker and shall be converted in accordance with
Section 3.3 hereof; provided further that if during the period between delivery of the Maker’s Prepayment Notice and the Maker’s Prepayment Date (as defined below), the Holder shall become entitled to deliver a Notice of
Prepayment at Option of Holder Upon Major Transaction or Notice of Prepayment at Option of Holder Upon Triggering Event, then such rights of the Holder, at its option, shall take precedence over the previously delivered Maker Prepayment Notice. The
Maker’s Prepayment Notice shall state the date of prepayment which date shall be the eleventh (11th) Trading Day after the Maker has
delivered the Maker’s Prepayment Notice (the “Maker’s Prepayment Date”), the Maker’s Prepayment Price and the principal amount of this Note to be prepaid by the Maker. The Maker shall deliver the Maker’s
Prepayment Price on the Maker’s Prepayment Date, provided, that if the Holder delivers a Conversion Notice before the Maker’s Prepayment Date, then the portion of the Maker’s Prepayment Price which would be paid to prepay this
Note covered by such Conversion Notice shall be returned to the Maker upon delivery of the Common Stock issuable in connection with such Conversion Notice to the Holder. On the Maker’s Prepayment Date, the Maker shall pay the Maker’s
Prepayment Price, subject to any adjustment pursuant to the immediately preceding sentence, to the Holder. If the Maker fails to pay the Maker’s Prepayment Price by the eleventh (11th) Trading Day after the Maker has delivered the Maker’s Prepayment Notice, the Maker’s Prepayment Notice will be declared null and void ab initio and the Maker
shall lose its right to prepay this Note pursuant to this Section 3.7(k). Notwithstanding the foregoing to the contrary, the Maker may effect a prepayment pursuant to this Section 3.7(k) only if (1) trading in the Common Stock shall
not have been suspended without resumption by the Securities and Exchange Commission or the OTC Bulletin Board (or other exchange or market on which the 

  

 -18- 

 
Common Stock is trading or quoted), (2) the Maker is in material compliance with the terms and conditions of this Note and the other Transaction
Documents, and (3) the Holder is not in possession of any material non-public information provided by Maker and (4) the Maker shall have filed all reports required to be filed by it under the Exchange Act for the preceding 12 months.

 Section 3.8 Inability to Fully Convert. 
 (a) Holder’s Option if Maker Cannot Fully Convert. If, upon the Maker’s receipt of a Conversion Notice, the Maker cannot issue shares of Common Stock pursuant to such Conversion Notice for any reason,
including, without limitation, because the Maker (w) does not have a sufficient number of shares of Common Stock authorized and available or (x) is otherwise prohibited by applicable law or by the rules or regulations of any stock
exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over the Maker or any of its securities from issuing all of the Common Stock which is to be issued to the Holder pursuant to a Conversion Notice, then the
Maker shall issue as many shares of Common Stock as it is able to issue in accordance with the Holder’s Conversion Notice and, with respect to the unconverted portion of this Note, the Holder, solely at Holder’s option, can elect to:

 (i) void its Conversion Notice and retain or have returned, as the case may be, this Note that was to be converted pursuant
to the Conversion Notice (provided that the Holder’s voiding its Conversion Notice shall not effect the Maker’s obligations to make any payments which have accrued prior to the date of such notice); 
 (ii) subject to Section 3.3(d) hereof, exercise its Buy-In rights pursuant to and in accordance with the terms and provisions of
Section 3.3(c) of this Note. 
 (b) Mechanics of Fulfilling Holder’s Election. The Maker shall promptly send via facsimile
to the Holder, upon receipt of a facsimile copy of a Conversion Notice from the Holder which cannot be fully satisfied as described in Section 3.8(a) above, a notice of the Maker’s inability to fully satisfy the Conversion Notice (the
“Inability to Fully Convert Notice”). Such Inability to Fully Convert Notice shall indicate (i) the reason why the Maker is unable to fully satisfy such holder’s Conversion Notice and (ii) the amount of this Note
which cannot be converted. The Holder shall notify the Maker of its election pursuant to Section 3.8(a) above by delivering written notice via facsimile to the Maker (“Notice in Response to Inability to Convert”). 

(c) Pro-rata Conversion. In the event the Maker receives a Conversion Notice from more than one holder of the Notes on the same day and the
Maker can convert some, but not all, of the Notes pursuant to this Section 3.8, the Maker shall convert from each holder of the Notes electing to have its Notes converted at such time an amount equal to such holder’s pro-rata amount (based
on the principal amount of the Notes held by such holder relative to the principal amount of the Notes outstanding) of all the Notes being converted at such time. 
  

 -19- 

 Section 3.9 No Rights as Shareholder. Nothing contained in this Note shall be construed as
conferring upon the Holder, prior to the conversion of this Note, the right to vote or to receive dividends or to consent or to receive notice as a shareholder in respect of any meeting of shareholders for the election of directors of the Maker or
of any other matter, or any other rights as a shareholder of the Maker. 
 ARTICLE IV 
 MISCELLANEOUS 
 Section 4.1 Notices. Any notice, demand, request,
waiver or other communication required or permitted to be given hereunder shall be in writing and shall be effective (a) upon hand delivery, telecopy or facsimile at the address or number designated in the Purchase Agreement (if delivered on a

(b) on the second business day following the date of mailing by express courier service, fully prepaid, addressed to such address, or upon actual receipt of such mailing, whichever shall first occur. The Maker will give written notice to the

thereof). The Maker acknowledges that a breach by it of its obligations hereunder will cause irreparable and material harm to the Holder and that the remedy at law for any such breach may be inadequate. Therefore the Maker agrees that, in the event
of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available rights and remedies, at law or in equity, to seek and obtain such equitable relief, including but not limited to an injunction restraining any
such breach or threatened breach, without the necessity of showing economic loss and without any bond or other security being required.

 FOR VALUE RECEIVED, the undersigned, FLO Corporation, a Delaware corporation (“Maker”),
promises to pay to the order of Unisys Corporation, a Delaware corporation (“Lender”), the principal amount of One Million Dollars ($1,000,000), together with interest thereon at the rate of 12% per annum from the date hereof until

 The principal of this Note and interest thereon shall be payable on August 8, 2009. Interest on the
principal balance hereof shall be computed based upon the actual number of days elapsed and a year of 365 days. 
 All of Maker’s
indebtedness and obligations to Lender under this Note shall be subordinated in right of payment, to the extent set forth below, to all Maker’s indebtedness under Maker’s 12% Senior Convertible Notes due 2010 (the “Senior
Notes”). 
 Payments of principal and interest hereunder shall be made to Lender’s account as specified by Lender in writing.
Payments shall be made in same day funds. 
 The following shall be Events of Default under this Note: 
  

	 	(1)	Maker shall fail to pay the principal of or interest on this Note when due; 

  

	 	(2)	Maker shall fail to pay any principal of or premium or interest on any Debt (as defined below) that is outstanding when the same shall become due and payable and such failure shall
continue after the applicable grace period, if any, specified in the agreement or instrument relating to any such Debt; or any other event shall occur or condition shall exist under any agreement or instrument relating to any Debt of Maker and shall
continue after the applicable grace period, if any, specified in such agreement or instrument, if the effect of such event or condition is to accelerate the maturity of such Debt; or any such Debt shall become due and payable prior to the stated
maturity thereof; 

  

	 	(3)	Maker shall generally not pay its debts as such debts become due, or shall admit in writing its inability to pay its debts generally, or shall make a general assignment for the
benefit of creditors; or any proceeding shall be instituted by or against Maker seeking to adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief or composition of it or
its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee, custodian or other similar official for it or for any
substantial part of its property and, in the case of any such proceeding instituted against it (but not instituted by it), either such proceeding shall remain undismissed or unstayed for a period of 60 days, or any of the actions sought in such
proceeding shall occur; or Maker shall take any corporate action to authorize any of the actions set forth above in this subparagraph. 

 Upon the occurrence of an Event of Default, the entire unpaid principal of this Note and the interest accrued thereon
shall, at the option of Lender, become immediately due and payable. 
 For purposes of paragraph (2) above, “Debt” shall mean
(a) indebtedness for borrowed money, (b) all obligations evidenced by notes, bonds, debentures or similar instruments, (c) obligations for the deferred purchase price of property or services (other than trade payables incurred in the

conditional sale or other title retention document with respect to property acquired by Maker and (e) all obligations in respect of acceptances, letters of credit or similar extensions of credit. 
 In the event that Maker does not pay the principal hereunder when due, interest on the entire unpaid principal amount of this Note shall increase to
18% per annum. 
 No payment shall be made by Maker on account of principal of or interest on this Note if there shall have occurred and
be continuing any default in the payment of principal, premium, if any, or interest on the Senior Notes continuing beyond the period of grace, if any, specified therein. Upon any distribution of assets of Maker upon any dissolution or winding-up or
liquidation or reorganization of Maker, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due or to become due under the Senior Notes shall first be paid in full before any payment is made
on account of the principal of or interest on this Note. 
 This Note may be prepaid at any time without premium or penalty. 
 Maker waives all requirements for presentment, protest, notice of protest, notice of dishonor, demand for payment and diligence in collection of this
Note. 
 This Note shall be governed by and construed in accordance with the laws of the State of Delaware.
