Company have the obligation to convert such Debenture (and the Company shall not have the right to pay interest hereon in shares of Common Stock) to the extent that, after such conversion or issuance of stock in payment of interest, the sum of
(1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Debentures or other
convertible securities or of the unexercised portion of warrants or other rights to purchase Common Stock), and (2) the number of shares of Common Stock issuable upon the conversion of the Debentures with respect to which the determination of this
proviso is being made, would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock (after taking into account the shares to be issued to the Holder upon such conversion). For
purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, except as otherwise provided in clause (1) of such
sentence. Nothing herein shall preclude the Holder from disposing of a sufficient number of other shares of Common Stock beneficially owned by the Holder so as to thereafter permit the continued conversion of this Debenture.

D. (i) Subject to the terms of Section 4(C) and to the other terms of this Section 4(D), interest on the principal amount of this Debenture
payable on an Interest Payment Date shall be due and payable, at the option of the Holder, in cash or in shares of Common Stock on the Interest Payment Date.

of the interest by the Interest Conversion Price in effect on the relevant Interest Payment Date.

not have the right to prepay any or all of the outstanding principal of this Debenture, without the prior written consent of the Holder in each instance (which consent may be withheld for any reason or no reason, in the sole discretion of the
Holder).

F. (i) The following provisions apply to the issuances of Common Stock in payment of the amounts due under this Debenture,
whether as principal or interest, as provided in the preceding provisions of this Section 4.

(ii) No fractional shares of Common
Stock or scrip representing fractions of shares will be issued on conversion, but the number of shares issuable shall be rounded to the nearest whole share.

(iii) All shares issuable with respect to a Conversion Date or an Interest Payment Date shall be deemed Conversion Shares for all purposes of this Debenture. Certificates representing the relevant
Conversion Shares (Conversion Certificates) will be delivered to the Holder at the address specified in the relevant Notice of Conversion. which address the Holder may change from time to time, via express courier, by electronic transfer
or otherwise, within three (3) Trading Days (such third Trading Day, the Delivery Date) after the relevant Conversion Date. The Holder shall be deemed to be the holder of the shares issuable to it in accordance with the relevant
provisions of this Debenture on the Conversion Date or Interest Payment Date, as the case may be.

G. Except as may specified in a specific
provision of this Debenture, any payments under this Debenture shall be applied in the following order of priority: (i) first to amounts due to the Holder for accrued but unpaid interest on this Debenture; and (ii) then, to principal of this
Debenture in the inverse order of maturity.

5. No provision of this Debenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of, and interest on, this Debenture at the time, place, and rate, and in the coin or currency or where contemplated

herein in shares of its Common Stock, as applicable, as herein prescribed. This Debenture and all other Debentures now or hereafter issued of similar terms
are direct obligations of the Company.

6. No recourse shall be had for the payment of the principal of, or the interest on, this
Debenture, or for any claim based hereon, or otherwise in respect hereof against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or any successor corporation, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

7. All payments contemplated hereby to be made in cash shall be made in immediately available good funds of United States of
America currency by wire transfer to an account designated in writing by the Holder to the Company (which account may be changed by notice similarly given). All payments of cash and each delivery of shares of Common Stock issuable to the Holder as
contemplated hereby shall be made to the Holder at the address last appearing on the Debenture Register of the Company as designated in writing by the Holder from time to time; except that the Holder can designate, by notice to the Company, a
different delivery address for any one or more specific payments or deliveries.

the Company enters into a merger (other than where the Company is the surviving entity) or consolidation with another corporation or other entity or a sale or transfer of all or substantially all of the assets of the Company to another person
(collectively, a Sale), the Company will require, in the agreements reflecting such transaction, that the surviving entity expressly assume the obligations of the Company hereunder. Notwithstanding the foregoing, if the Company enters
into a Sale and the holders of the Common Stock are entitled to receive stock, securities or property in respect of or in exchange for Common Stock, then as a condition of such Sale, the Company and any such successor, purchaser or transferee will
agree that the Debenture may thereafter be converted on the terms and subject to the conditions set forth above into the kind and

which this Debenture might have been converted immediately before such merger, consolidation, sale or transfer, subject to adjustments which shall be as nearly equivalent as may be practicable. In the event of any such proposed Sale, (i) the Holder
hereof shall have the right to convert by delivering a Notice of Conversion to the Company within fifteen (15) days of receipt of notice of such Sale from the Company, except that Section 4(C) shall not apply to such conversion.

9. If, at any time while any portion of this Debenture remains outstanding, the Company spins off or otherwise divests itself of a part of
its business or operations or disposes of all or of a part of its assets in a transaction (the Spin Off) in which the Company, in addition to or in lieu of any other compensation received and retained by the Company for such business,
operations or assets, causes securities of another entity (the Spin Off Securities) to be issued to security holders of the Company, the Company shall cause (i) to be reserved Spin Off Securities equal to the number thereof which
would have been issued to the Holder had all of the Holders Debentures outstanding on the record date (the Record Date) for determining the amount and number of Spin Off Securities to be issued to security holders of the Company
(the Outstanding Debentures) been converted as of the close of business on the Trading Day immediately before the Record Date (the Reserved Spin Off Shares), and (ii) to be issued to the Holder on the conversion of all
or any of the Outstanding Debentures, such amount of the Reserved Spin Off Shares equal to (x) the Reserved Spin Off Shares multiplied by (y) a fraction, of which (I) the numerator is the principal amount of the Outstanding Debentures
then being converted, and (II) the denominator is the principal amount of the Outstanding Debentures.

10. If, at any time while any
portion of this Debenture remains outstanding, the Company effectuates a stock split or reverse stock split of its Common Stock or issues a dividend on its Common Stock consisting of shares of Common Stock, the prices used in determining the
Conversion Price from dates prior to such action or and any other fixed amounts calculated as contemplated hereby or by any of the other Transaction Agreements shall be equitably adjusted to reflect such action.

state Blue Sky or foreign laws or similar laws relating to the sale of securities.

12. This Debenture shall be governed by and construed
in accordance with the laws of the State of Florida for contracts to be wholly performed in such state and without giving effect to the principles thereof regarding the conflict of laws. Each of the parties consents to the exclusive jurisdiction of
the federal courts whose districts encompass any part of the County of Broward or the state courts of the State of Florida sitting in the County of Broward in connection with any dispute arising under this Debenture and hereby waives, to the maximum
extent permitted by law, any objection, including any objection based on forum non coveniens, to the bringing of any such proceeding in such jurisdictions. To the extent determined by such court, the Company shall reimburse the Holder for any
reasonable legal fees and disbursements incurred by the Holder in enforcement of or protection of any of its rights under any of this Debenture.

13. JURY TRIAL WAIVER.The Company and the Holder hereby waive a trial by jury in any action, proceeding or counterclaim brought by either of the Parties hereto against the other in respect of any matter arising out of or in

have the right at any time thereafter, by written notice to the Company (the Change in Control Demand Notice), to demand payment in full of the outstanding principal of this Debenture together with all accrued but unpaid interest
thereon. The Company will be obligated to pay such amount (with interest calculated through the actual date of payment; such total, the Change in Control Redemption Amount ) by the date (the Change in Control Redemption Due
Date) which is five (5) Trading Days after the Companys receipt of the Change in Control Demand Notice.

C. (i) The Change
in Control Redemption Amount shall be payable in cash, except as provided in clause (ii) of this subparagraph 14(C).

(ii) If, but
only if, no later than the Change in Control Redemption Due Date, the Company can deliver to the Holder registered shares of Common Stock which the Holder can resell without restriction, the Company may elect to pay the Control Redemption Amount in
such shares. The number of shares to be so delivered shall be equal to the sum of (x) the number of shares equal to the outstanding principal of the Debenture divided by the Fixed Conversion Price in effect on the Change in Control Redemption
Date (or earlier payment date), plus (y) the number of shared equal to the accrued but unpaid interest being paid divided by the Interest Conversion in effect on the Change in Control Redemption Date (or earlier payment date); provided,
however, that the provisions of Section 4(C) hereof shall apply to the number of shares issuable to the Holder.

Event of Default means the occurrence of any one or more of the following events:

12

below). The Redemption Amount shall be paid in cash by the Company to the Holder. The Redemption Amount shall be applied in the priority provided in
Section 4(I) hereof.

B. For purposes of this Debenture, the following terms shall have the meanings indicated below:

Unconverted Debenture means the principal amount of this Debenture which has not been converted as of the relevant date.

Redemption Payment Date means the date on which the Company actually pays the Redemption Amount.

|  |    |   |  |  
|- | -- | - |  | -
|M |    | V |  | x

where:

V means the principal of an Unconverted Debenture plus any accrued but unpaid interest thereon;

defined below); provided, however, if the Redemption Amount is not paid in full on or before the Redemption Due Date, CP means the lower of (x) the Conversion Price in effect on the Redemption Notice Date or (y) the lowest
Conversion Price in effect during the period commencing on the Redemption Due Date and ending on the Redemption Payment Date; and

M means the highest closing price per share of the Common Stock during the period beginning on the Redemption Notice Date and ending on the Redemption Payment Date.



13



---

C. The Holder of an Unconverted Debenture may elect to redeem a portion of such Unconverted Debenture
without electing to redeem the balance of the Unconverted Debenture. The Holders option to redeem all or part of the Unconverted Debenture shall be exercised by the Holder giving written notice of the exercise of this provision by the Holder
(a Redemption Notice) at any time after a relevant Event of Default has occurred but before such Event of Default is cured. The Redemption Notice shall specify (a) the date (the Redemption Due Date) on which the
Redemption Amount shall be paid, which date shall be at least five (5) Trading Days after the date (a Redemption Notice Date) on which the Holder Redemption Notice is given, and (b) the wire instructions for the account to
which the Redemption Amount is to be paid; provided, however, that the Company shall have the right to accelerate the date of such payment.

D. If all of the Unconverted Debentures are being redeemed pursuant to this Section 16, then, upon payment in full of the Redemption Amount for all of the Unconverted Debentures in accordance with the provisions of this
Section 16, the Holder shall deliver the Debenture to the Company marked paid in full.

E. If the Redemption Amount is not
timely paid by the Company, the Redemption Amount shall accrue interest at the Default Rate and the Holder may declare the Redemption Amount, together with such interest, due under this Debenture immediately due and payable, without presentment,
demand, protest or notice of any kinds, all of which are hereby expressly waived, anything herein or in any note or other instruments contained to the contrary notwithstanding, and the Holder may immediately enforce any and all of the Holders
rights and remedies provided herein or any other rights or remedies afforded by law, including, but not necessarily limited to, the equitable remedy of specific performance and injunctive relief.

17. Nothing contained in this Debenture shall be construed as conferring upon the Holder the right to vote or to receive dividends or to consent or
receive notice as a shareholder in respect of any meeting of shareholders or any rights whatsoever as a shareholder of the Company, unless and to the extent converted in accordance with the terms hereof.



14



---

19. In the event for any reason, any payment by or act of the Company or the Holder shall result in
payment of interest which would exceed the limit authorized by or be in violation of the law of the jurisdiction applicable to this Debenture, then ipso factothe obligation of the Company to pay interest or perform such act or requirement
shall be reduced to the limit authorized under such law, so that in no event shall the Company be obligated to pay any such interest, perform any such act or be bound by any requirement which would result in the payment of interest in excess of the
limit so authorized. In the event any payment by or act of the Company shall result in the extraction of a rate of interest in excess of a sum which is lawfully collectible as interest, then such amount (to the extent of such excess not returned to
the Company) shall, without further agreement or notice between or by the Company or the Holder, be deemed applied to the payment of principal, if any, hereunder immediately upon receipt of such excess funds by the Holder, with the same force and
effect as though the Company had specifically designated such sums to be so applied to principal and the Holder had agreed to accept such sums as an interest- free prepayment of this Debenture. If any part of such excess remains after the principal
has been paid in full, whether by the provisions of the preceding sentences of this Section or otherwise, such excess shall be deemed to be an interest-free loan from the Company to the Holder, which loan shall be payable immediately upon demand by
the Company. The provisions of this Section shall control every other provision of this Debenture.

IN WITNESS WHEREOF, the Company has
caused this instrument to be duly executed by an officer thereunto duly authorized.
