- 3 -

Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before 4:00 p.m., New York Time, on the first (1 ^st ) Business Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Company’s transfer agent, if any (the “ Transfer Agent ”). On or before 4:00 p.m., New York Time, on the third Business Day following the date of receipt of a Conversion Notice (the “ Share Delivery Date ”), the Company shall (X) provided that the Transfer Agent, if any, is participating in the Depository Trust Company (“ DTC ”) Fast Automated Securities Transfer Program, credit such aggregate number of shares of Class A Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or if the foregoing is not applicable, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Class A Common Stock to which the Holder shall be entitled. If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with Section 19(d)) representing the outstanding Principal not converted.

(ii) Company’s Failure to Timely Convert . If, at any time, the Company shall fail to issue a certificate to the Holder or, from and after an Effective Registration, credit the Holder’s balance account with DTC for the number of shares of Class A Common Stock to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is five Business Days after the Conversion Date (a “ Conversion Failure ”), then (A) the Company shall pay damages to the Holder for each date of such Conversion Failure in an amount equal to 1.5% of the product of (I) the sum of the number of shares of Class A Common Stock not issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, and (II) the Closing Sale Price of the Class A Common Stock on the Share Delivery Date and (B) the Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such Conversion Notice; provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In lieu of the foregoing, if within three (3) Business Days after the Company’s receipt of the facsimile copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of shares of Class A Common Stock to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) shares of Class A

- 4 -

Common Stock to deliver in satisfaction of a sale by the Holder of Class A Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a “ Buy-In ”), then the Holder may elect to require the Company to, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Class A Common Stock so purchased (the “Buy-In Price” ), at which point the Company’s obligation to deliver such certificate (and to issue such Class A Common Stock) shall terminate, or (ii) in the case of an Effective Registration, promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Class A Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Class A Common Stock times (B) the Closing Bid Price on the Conversion Date.

(iii) Book-Entry . Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting physical surrender and reissue of this Note. The Holder and the Company shall maintain records showing the Principal, Interest and Late Charges converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

(iv) Pro Rata Conversion; Disputes . In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of each such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Class A Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Class A Common Stock not in dispute and resolve such dispute in accordance with Section 24.

(d) Limitations on Conversions . From and after an Effective Registration and other than in connection with a Fundamental Transaction, the Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert any portion of this Note pursuant to Section 3(a), to the extent that after giving effect to such conversion, the Holder (together with the Holder’s affiliates) would beneficially own in excess of 9.99% (the “ Maximum Percentage ”) of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of

- 5 -

Class A Common Stock issuable upon conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any Additional Notes or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 3(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Section 3(d), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Form 10-KSB, Form 10-K, Form 10-QSB, Form 10-Q or Form 8-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within two (2) Business Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61 ^st ) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes. Notwithstanding anything in this Section 3(d) to the contrary, it is agreed and understood that the limitation on conversions contained in this Section 3(d) shall in no way limit any of the Company’s rights under Sections 8(a) and 8(c) of this Note.

Company under this Note with the same effect as if such Successor Entity had been named as the Company herein, until such time as the Successor Note is delivered.

At any time during the period (the “ Change of Control Measuring Period ”) beginning after the Holder’s receipt of a Change of Control Notice and ending on the date of the consummation of such Change of Control (or, in the event a Change of Control Notice is not delivered at least ten (10) days prior to a Change of Control, at any time on or after the date which is ten (10) days prior to a Change of Control and ending ten (10) days after the consummation of such Change of Control), the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“ Change of Control Redemption Notice ”) to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company at a price (the “ Change of Control Redemption Price ”) equal to the greatest of (i) the sum of (A) the product of (x) the Conversion Amount being redeemed and (y) the quotient determined by dividing (I) the Closing Sale Price of the Class A Common Stock immediately following the public announcement of such proposed Change of Control by (II) the Conversion Price and (B) the Present Value of Interest, or (ii) the sum of (A) the value of the consideration, assuming that the entire Conversion Amount being redeemed were converted into shares of Class A Common Stock at the then prevailing Conversion Rate, issuable per share of Common Stock in such Change of Control for the entire Conversion Amount being redeemed and (B) the Present Value of Interest (if any) and (iii) the sum of (A) the Conversion Amount being redeemed and (B) the Present Value of Interest (if any).

In addition to the foregoing, at the time of the consummation of any such Change of Control, the Company shall pay to the Holder an amount in cash equal to the Present Value of Interest (if any) for any Conversion Amount converted pursuant to the provisions of Section 3 hereof during the Change of Control Measuring Period.

(6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS .

(a) Purchase Rights . If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “ Purchase Rights ”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Class A Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(b) Other Corporate Events . In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “ Corporate Event ”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, (i) in the event that the Class A Common Stock remains outstanding after any such Corporate Event, in addition to the shares of Class A Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Class A Common Stock had such shares of Class A Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in the event that the Class A Common Stock is no longer outstanding after any such Corporate Event, in lieu of the shares of Class A Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Class A Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note. Notwithstanding this Section (6)(b), in no event shall the Company be obligated to distribute any Purchase Rights pursuant to this Section (6)(b) if and to the extent that it has distributed such Purchase Rights to the Holder pursuant to Section (6)(a).

issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock issued or sold or deemed to have been issued or sold by the Company with respect to Options to acquire up to 6,000,000 shares of Common Stock that may be awarded by the Company solely to employees, officers and directors for services provided to the Company) for a consideration per share (the “ New Issuance Price ”) less than a price (the “ Pre-Qualified IPO Applicable Price ”) equal to the Conversion Price in effect immediately prior to such issue or sale (the foregoing issuance, a “ Pre-Qualified IPO Dilutive Issuance ”), then immediately after such Pre-Qualified IPO Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price. If and whenever on or after the consummation of a Qualified IPO, the Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock issued or sold or deemed to have been issued or sold by the Company in each case solely in connection with any Excluded Security) for a consideration per share less than a price (the “ Post-Qualified IPO Applicable Price ”) equal to the Market Price then in effect (the foregoing issuance, a “ Post-Qualified IPO Dilutive Issuance ”), then immediately after such Post-Qualified IPO Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the product of (i) the Conversion Price in effect immediately prior to such issuance or sale and (ii) the quotient determined by dividing (A) the sum of (1) the product derived by multiplying the Post-Qualified IPO Applicable Price and the number of shares of Common Stock Deemed Outstanding immediately prior to such Post-Qualified IPO Dilutive Issuance plus (2) the consideration, if any, received by the Company upon such Post-Qualified IPO Dilutive Issuance, by (B) the product derived by multiplying (1) the Post-Qualified IPO Applicable Price by (2) the number of shares of Common Stock Deemed Outstanding immediately after such Post-Qualified IPO Dilutive Issuance. For purposes of determining the adjusted Conversion Price under this Section 7(a), the following shall be applicable:

(i) Issuance of Options . If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Pre-Qualified IPO Applicable Price or the Post-Qualified IPO Applicable Price, as the case may be, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 7(a)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock (A) upon granting or sale of the Option, (B) upon exercise of the Option and (C) upon conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange or exercise of such Convertible Securities.

(ii) Issuance of Convertible Securities . If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise thereof is less than the Pre-Qualified IPO Applicable Price or the Post-Qualified IPO Applicable Price, as the case may be, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the “price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock (A) upon the issuance or sale of the Convertible Security and (B) upon the conversion or exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock upon conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

(iii) Change in Option Price or Rate of Conversion . If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the Subscription Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made (x) pursuant to this Section (7)(a)(iii) if an adjustment of the Conversion Price has been or is to be made pursuant to other provisions of this Section 7(a) in connection therewith or (y) if such adjustment would result in an increase of the Conversion Price then in effect.

(iv) Calculation of Consideration Received . In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any

Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such securities on the date of receipt. If any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in con
