e)

Section
4. Conversion.


 


a)
Voluntary Conversion. At any time after the Closing Date, until this Note is no longer outstanding, this Note shall be
convertible, in whole or in part, into shares of Common Stock at the option of the Holder, at any time and from time to time (subject
to the conversion limitations set forth in Section 4(d) hereof). The Holder shall effect conversions by delivering to Borrower
a Notice of Conversion, the form of which is attached hereto as Annex A (each, a “Notice of Conversion”),
specifying therein the principal amount of this Note and accrued interest, if any, to be converted at the election of the Holder
and the date on which such conversion shall be effected (such date, the “Conversion Date”). If no Conversion
Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered
hereunder. To effect conversions hereunder, the Holder shall not be required to physically surrender this Note to Borrower unless
the entire principal amount of this Note has been so converted. Conversions of principal hereunder shall have the effect of lowering
the outstanding principal amount of this Note in an amount equal to the applicable conversion. The Holder and Borrower shall maintain
records showing the principal amount(s) converted and the date of such conversion(s). Borrower may deliver an objection to any
Notice of Conversion within one (1) Business Day of delivery of such Notice of Conversion. In the event of any dispute or discrepancy,
the records of the Holder shall be controlling and determinative in the absence of manifest error. The Holder, and any assignee
by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of
a portion of this Note, the unpaid and unconverted principal amount of this Note may be less than the amount stated on the face
hereof.


 


b)
Conversion Price. The conversion price for the principal and interest in connection with voluntary conversions by the Holder
shall be 70% multiplied by the Market Price (as defined herein)(representing a discount rate of 30%), subject to adjustment as
described herein (“Conversion Price”). Market Price” means the lowest one (1) Trading Prices (as defined
below) for the Common Stock during the twenty (20) Trading Day period ending on the last complete Trading Day prior to the Conversion
Date. “Trading Prices” means, for any security as of any date, the lowest traded price on the Over-the Counter Pink
Marketplace, OTCQB, or applicable trading market (the “OTCQB”) as reported by a reliable reporting service (“Reporting
Service”) designated by the Holder (i.e. www.Nasdaq.com) or, if the OTCQB is not the principal trading market for such security,
on the principal securities exchange or trading market where such security is listed or traded or, if the lowest intraday trading
price of such security is not available in any of the foregoing manners, the lowest intraday price of any market makers for such
security that are quoted on the OTC Markets. If the Trading Prices cannot be calculated for such security on such date in the
manner provided above, the Trading Prices shall be the fair market value as mutually determined by the Borrower and the holders
of a majority in interest of the Notes being converted for which the calculation of the Trading Prices are required in order to
determine the Conversion Price of such Notes. “Trading Day” shall mean any day on which the Common Stock is tradable
for any period on the OTCQB, or on the principal securities exchange or other securities market on which the Common Stock is then
being traded. Upon any Event of Default, including not having current financial information publicly disclosed, the Conversion
Price will be reduced to 60% multiplied by the Market Price (as defined herein)(representing a discount rate of 40%).


 


c)
Mechanics of Conversion.


 


i.
Conversion Shares Issuable Upon Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion
hereunder shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Note to be converted
plus interest, if any, elected by the Holder to be converted by (y) the Conversion Price. Upon every Conversion, the Company shall
deliver an additional $500 worth of shares (as calculated by the Conversion Price in effect on the Conversion Notice being honored)
to cover the Holder’s expenses and deposit fees associated with each Notice of Conversion.


 




    	 	5	 



     


    

 


ii.
Delivery of Certificate Upon Conversion. Not later than five (5) Trading Days after each Conversion Date (the “Share
Delivery Date”), Borrower shall deliver, or cause to be delivered, to the Holder a certificate or certificates representing
the Conversion Shares which, on or after the earlier of (i) the six month anniversary of the Original Issue Date or (ii) the Effective
Date, shall be free of restrictive legends and trading restrictions (other than those which may then be required by the Purchase
Agreement) representing the number of Conversion Shares being acquired upon the conversion of this Note. On or after the earlier
of (i) the six-month anniversary of the Original Issue Date or (ii) the Effective Date, Borrower shall in lieu of delivering physical
certificates representing the Conversion Shares, upon request of the Holder, so long as the certificates therefor do not bear
a legend and the Holder is not obligated to return such certificate for the placement of a legend thereon, the Borrower shall
cause its transfer agent to electronically transmit the Conversion Shares by crediting the account of Holder’s prime broker
with the Depository Trust Company through its Deposit Withdrawal At Custodian system, provided that the Borrower’s Common
Stock is DTC eligible and the Borrower’s transfer agent participates in the Deposit Withdrawal at Custodian system. Such
delivery must be made on or before the Legend Removal Date.


 


iii.
Failure to Deliver Certificates. If, in the case of any Notice of Conversion, such certificate or certificates are not
delivered to or as directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written
notice to Borrower at any time on or before its receipt of such certificate or certificates, to rescind such Conversion, in which
event Borrower shall promptly return to the Holder any original Note delivered to Borrower and the Holder shall promptly return
to Borrower the Common Stock certificates issued to such Holder pursuant to the rescinded Conversion Notice.


 


iv.
Obligation Absolute. Borrower’s obligations to issue and deliver the Conversion Shares upon conversion of this Note
in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce
the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action
to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the
Holder or any other Person of any obligation to Borrower or any violation or alleged violation of law by the Holder or any other
Person, and irrespective of any other circumstance which might otherwise limit such obligation of Borrower to the Holder in connection
with the issuance of such Conversion Shares; provided, however, that such delivery shall not operate as a waiver
by Borrower of any such action Borrower may have against the Holder. In the event the Holder of this Note shall elect to convert
any or all of the outstanding principal amount hereof, Borrower may not refuse conversion based on any claim that the Holder or
anyone associated or affiliated with the Holder has been engaged in any violation of law, agreement or for any other reason, unless
an injunction from a court, on notice to Holder, restraining and or enjoining conversion of all or part of this Note shall have
been sought and obtained, and Borrower posts a surety bond for the benefit of the Holder in the amount of 150% of the outstanding
principal amount of this Note, which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation
of the underlying dispute and the proceeds of which shall be payable to the Holder to the extent it obtains judgment. In the absence
of such injunction, Borrower shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion. If Borrower
fails for any reason to deliver to the Holder such certificate or certificates pursuant to Section 4(c)(ii) by the Share Delivery
Date, Borrower shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of principal amount
being converted, $10 per Trading Day (increasing to $20 per Trading Day on the fifth (5th) Trading Day after such liquidated
damages being to accrue) for each Trading Day after such Share Delivery Date until such certificates are delivered or Holder rescinds
such conversion. Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant
to Section 8 hereof for Borrower’s failure to deliver Conversion Shares within the period specified herein and the Holder
shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree
of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to
enforce damages pursuant to any other Section hereof or under applicable law.


 




    	 	6	 



     


    

 


v.
Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. In addition to any other rights available
to the Holder, if Borrower fails for any reason to deliver to the Holder such certificate or certificates by the Share Delivery
Date pursuant to Section 4(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase
(in an open market transaction or otherwise), or the Holder or Holder’s brokerage firm otherwise purchases, shares of Common
Stock to deliver in satisfaction of a sale by the Holder of the Conversion Shares which the Holder was entitled to receive upon
the conversion relating to such Share Delivery Date (a “Buy-In”), then Borrower shall (A) pay in cash to the
Holder (in addition to any other remedies available to or elected by the Holder) the amount, if any, by which (x) the Holder’s
total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the
aggregate number of shares of Common Stock that the Holder was entitled to receive from the conversion at issue multiplied by
(2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage
commissions) and (B) at the option of the Holder, either reissue (if surrendered) this Note in a principal amount equal to the
principal amount of the attempted conversion (in which case such conversion shall be deemed rescinded) or deliver to the Holder
the number of shares of Common Stock that would have been issued if Borrower had timely complied with its delivery requirements
under Section 4(c)(ii). 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 this Note with respect to which the actual sale price of the Conversion Shares
(including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately
preceding sentence, Borrower shall be required to pay the Holder $1,000. The Holder shall provide Borrower written notice indicating
the amounts payable to the Holder in respect of the Buy-In and, upon request of Borrower, evidence of the amount of such loss.
Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity
including, without limitation, a decree of specific performance and/or injunctive relief with respect to Borrower’s failure
to timely deliver certificates representing shares of Common Stock upon conversion of this Note as required pursuant to the terms
hereof.


 


vi.
Reservation of Shares Issuable Upon Conversion. Borrower covenants that it will at all times reserve and keep available
out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Note as herein
provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the
other holders of the Notes), not less than three times such aggregate number of shares of the Common Stock as shall (subject to
the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions
of Section 5) upon the conversion of the then outstanding principal amount of this Note and interest which has accrued and would
accrue on such principal amount, assuming such principal amount was not converted through three years after the Original Issue
Date. Borrower covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly
issued, fully paid and nonassessable.


 




    	 	7	 



     


    

 


vii.
Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of
this Note. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, Borrower
shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the Conversion Price or round up to the next whole share.


 


viii.
Transfer Taxes and Expenses. The issuance of certificates for shares of the Common Stock on conversion of this Note shall
be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue
or delivery of such certificates, provided that, Borrower shall not be required to pay any tax that may be payable in respect
of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the
Holder of this Note so converted and Borrower shall not be required to issue or deliver such certificates unless or until the
Person or Persons requesting the issuance thereof shall have paid to Borrower the amount of such tax or shall have established
to the satisfaction of Borrower that such tax has been paid. Borrower shall pay all Transfer Agent fees required for same-day
processing of any Notice of Conversion.


 


d)
Holder’s Conversion Limitations. Borrower shall not effect any conversion of this Note, and a Holder shall not have
the right to convert any portion of this Note, to the extent that after giving effect to the conversion set forth on the applicable
Notice of Conversion, the Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with
the Holder or any of the Holder’s Affiliates) would beneficially own in excess of the Beneficial Ownership Limitation (as
defined below). 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 Common Stock issuable upon conversion of this Note with respect to which
such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion
of the remaining, unconverted principal amount of this Note beneficially owned by the Holder or any of its Affiliates and (ii)
exercise or conversion of the unexercised or unconverted portion of any other securities of Borrower subject to a limitation on
conversion or exercise analogous to the limitation contained herein (including, without limitation, any other Notes or the Warrants)
beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this
Section 4(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and
regulations promulgated thereunder. To the extent that the limitation contained in this Section 4(d) applies, the determination
of whether this Note is convertible (in relation to other securities owned by the Holder together with any Affiliates) and of
which principal amount of this Note is convertible shall be in the sole discretion of the Holder, and the submission of a Notice
of Conversion shall be deemed to be the Holder’s determination of whether this Note may be converted (in relation to other
securities owned by the Holder together with any Affiliates) and which principal amount of this Note is convertible, in each case
subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, the Holder will be deemed to represent
to Borrower each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set
forth in this paragraph and Borrower shall have no obligation to verify or confirm the accuracy of such determination. In addition,
a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(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 stated in the most recent of
the following: (i) Borrower’s most recent periodic or annual report filed with the Commission, as the case may be, (ii)
a more recent public announcement by Borrower, or (iii) a more recent written notice by Borrower or Borrower’s transfer
agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, Borrower shall
within two Trading 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 Borrower, 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. The “Beneficial Ownership Limitation” shall be 4.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon
conversion of this Note held by the Holder. The Holder may decrease the Beneficial Ownership Limitation at any time and the Holder,
upon not less than 61 days’ prior notice to Borrower, may increase the Beneficial Ownership Limitation provisions of this
Section 4(d), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common
Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Note held
by the Holder and the Beneficial Ownership Limitation provisions of this Section 4(d) shall continue to apply. Any such increase
will not be effective until the 61st day after such notice is delivered to Borrower. The Beneficial Ownership Limitation
provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms
of this Section 4(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect
to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Note.

or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or
other business combination) (each a “Fundamental Transaction”), then, upon any subsequent conversion of this
Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion
immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion
of this Note), the number of shares of Common Stock of the successor or acquiring corporation or of Borrower, if it is the surviving
corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such
Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note is convertible immediately prior
to such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion of this Note). For purposes
of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration
based on the amount of Alternate Consideration issuable in respect of one (1) share of Common Stock in such Fundamental Transaction,
and Borrower shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative
value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities,
cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate
Consideration it receives upon any conversion of this Note following such Fundamental Transaction. Borrower shall cause any successor
entity in a Fundamental Transaction in which Borrower is not the survivor (the “Successor Entity”) to assume
in writing all of the obligations of Borrower under this Note and the other Transaction Documents (as defined in the Purchase
Agreement) in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably
satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall,
at the option of the holder of this Note, deliver to the Holder in exchange for this Note a security of the Successor Entity evidenced
by a written instrument substantially similar in form and substance to this Note which is convertible for a corresponding number
of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable
and receivable upon conversion of this Note (without regard to any limitations on the conversion of this Note) prior to such Fundamental
Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital stock (but taking
into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares
of capital stock, such number of shares of capital stock and such conversion price being for the purpose of protecting the economic
value of this Note immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory
in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed
to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note and the
other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise
every right and power of Borrower and shall assume all of the obligations of Borrower under this Note and the other Transaction
Documents with the same effect as if such Successor Entity had been named as Borrower herein.

as the case may be. For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as
of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of Borrower) issued and
outstanding.

Borrower shall promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth

Borrower shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any
shares of capital stock of any class or of any rights, (D) the approval of any stockholders of Borrower shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which Borrower is a party, any sale or transfer
of all or substantially all of the assets of Borrower, or any compulsory share exchange whereby the Common Stock is converted
into other securities, cash or property or (E) Borrower shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of Borrower, then, in each case, Borrower shall cause to be filed at each office or agency maintained
for the purpose of conversion of this Note, and shall cause to be delivered to the Holder at its last address as it shall appear
upon the Note Register, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified,
a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights
or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled
to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it
is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities,
cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided
that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the
corporate action required to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains,
material, non-public information regarding Borrower or any of the Subsidiaries, Borrower shall simultaneously file such notice
with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to convert this Note during the
20-day period commencing on the date of such notice through the effective date of the event triggering such notice except as may
otherwise be expressly set forth herein.
