SENIOR
SECURED CONVERTIBLE NOTE


 


	Issuance
    Date: July 27, 2016	Original
    Principal Amount: U.S. $150,000


 


FOR
VALUE RECEIVED, Enerpulse Technologies, Inc., a Nevada corporation (the “Company”), hereby promises to
pay to Passaic River Capital LLC or registered assigns (the “Holder”) in cash and/or in shares of Common Stock
(as defined below) the amount set out above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant
to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined
below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”)
on any outstanding Principal at the applicable Interest Rate from the date set out above as the Issuance Date (the “Issuance
Date”) until the same becomes due and payable, whether upon the Maturity Date, acceleration, conversion, redemption
or otherwise (in each case in accordance with the terms hereof). This Senior Secured Convertible Note was issued pursuant to the
Securities Purchase Agreement on the Closing Date (the “Note”). Certain capitalized terms used herein are defined
in Section 28.


 


(1)PAYMENTS
OF PRINCIPAL; PREPAYMENT. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding
Principal and accrued and unpaid Interest on such Principal. The “Maturity Date” shall be July 27, 2019
(the “Scheduled Maturity Date”), as may be extended at the option of the Holder (i) in the event that, and
for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing on the Maturity Date (as
may be extended pursuant to this Section 1) and (ii) through the date that is ten (10) Business Days after the consummation of
a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section
5(b)) is delivered prior to the Maturity Date; provided, that no Interest shall accrue hereunder from and after the Scheduled
Maturity Date if the Maturity Date has been extended at the Holder’s option pursuant to clause (ii) above. Other than as
specifically permitted by this Note, the Company may not prepay any portion of the outstanding Principal or accrued and unpaid
Interest on Principal, if any.


 




    	 



    	 



    

 


(2)INTEREST.


 


(a)Interest
on this Note shall commence accruing on the Issuance Date at the Interest Rate and shall be computed on the basis of a 360-day
year and twelve 30-day months and shall be payable in arrears on the Maturity Date. Interest shall be payable on the Maturity
Date, to the record holder of this Note on the Maturity Date in shares of Common Stock (“Interest Shares”)
so long as there has been no Equity Conditions Failure during the period from the Interest Notice Date (as defined below) through
the Maturity Date; provided, however, that the Company may, at its option following written notice to the Holder,
pay Interest on the Maturity Date in cash (“Cash Interest”) or in a combination of Cash Interest and Interest
Shares. The Company shall deliver a written notice (the “Interest Election Notice”) to the holder of this Note
(the date such notice is delivered to the Holder, the “Interest Notice Date”) which notice (i) either (a) confirms
that Interest to be paid on the Maturity Date shall be paid entirely in Interest Shares, or (b) elects to pay Interest on the
Maturity Date as Cash Interest or a combination of Cash Interest and Interest Shares and specifies the amount of Interest that
shall be paid as Cash Interest and the amount of Interest, if any, that shall be paid in Interest Shares which amounts, when added
together, must at least equal the Interest due on the Maturity Date, and (ii) if Interest is to be paid, in whole or in part,
in Interest Shares, certifies that there has been no Equity Conditions Failure as of such Interest Notice Date. If there is an
Equity Conditions Failure as of the Interest Notice Date, then unless the Company has elected to pay such Interest as Cash Interest,
the Interest Election Notice shall indicate that unless the Holder waives the Equity Conditions Failure, the Interest shall be
paid as Cash Interest. If the Company confirmed (or is deemed to have confirmed by operation of this Section 2) the payment of
the Interest in Interest Shares, in whole or in part, and if there was no Equity Conditions Failure as of the Interest Notice
Date (or is deemed to have certified that there has been no Equity Conditions Failure in connection with such Interest payment
in Interest Shares by operation of this Section 2) but an Equity Conditions Failure occurred between the Interest Notice Date
and any time prior to the Maturity Date (the “Interest Interim Period”), the Company shall provide the Holder
a subsequent notice to that effect indicating that unless the Holder waives the Equity Conditions Failure, the Interest shall
be paid as Cash Interest. If there is an Equity Conditions Failure (which is not waived in writing by the Holder) during the Interest
Interim Period, then at the option of the Holder, the Holder may require the Company to pay the amount of Interest payable on
the Maturity Date as Cash Interest. Interest to be paid on the Maturity Date in Interest Shares shall be paid in a number of fully
paid and nonassessable shares (rounded to the nearest whole share in accordance with Section 3(a)) of Common Stock equal to (i)
the amount of Interest payable on the Maturity Date less any Cash Interest paid, divided by (ii) the Interest Conversion Price
in effect on the Maturity Date. If the Company does not timely deliver an Interest Election Notice in accordance with this Section
2(a), then the Company shall be deemed to have delivered an irrevocable Interest Election Notice confirming the payment of Interest
in Interest Shares and shall be deemed to have certified that in connection with the delivery of Interest Shares on the Maturity
Date no Equity Conditions Failure has occurred.

(b)When
any Interest Shares are to be paid on the Maturity Date, the Company shall (i) (a) provided that the Company’s transfer
agent (the “Transfer Agent”), if any, is participating in the Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program, credit such aggregate number of Interest Shares to which the Holder shall be entitled
to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian system, or
(b) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or if the Company does not
have a transfer agent, issue and deliver on the Interest Notice Date and the Maturity Date, to the address set forth in the register
maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the
Holder in writing to the Company at least two (2) Business Days prior to the Maturity Date a certificate, registered in the name
of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled, and (ii) pay to the Holder,
in cash by wire transfer of immediately available funds, the amount of any Cash Interest.


 


(c)Prior
to the payment of Interest on the Maturity Date, Interest on this Note shall accrue at the Interest Rate and be payable by way
of inclusion of the Interest in the Conversion Amount (as defined in Section 3(b)(i)) on each Share Delivery Date (as defined
in Section 3(c)(i)) in accordance with Section 3(b)(i) and on each Redemption Date in accordance with Section 4(b) or Section
5(b), as applicable. From and after the occurrence and during the continuance of an Event of Default, the Interest Rate shall
be increased to eighteen percent (18.0%). In the event that such Event of Default is subsequently cured, the adjustment referred
to in the preceding sentence shall cease to be effective as of the date of such cure; provided, that the Interest as calculated
and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating
to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default; provided,
further, that for the purpose of this Section 2, such Event of Default shall not be deemed cured unless and until any accrued
and unpaid Interest shall be paid to the Holder, including, without limitation, Interest accrued at the increased rate of eighteen
percent (18.0%). The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of Interest
Shares pursuant to this Section 2.


 


(3)CONVERSION
OF NOTES. At any time or times after the Issuance Date, this Note shall be convertible into shares of the Company’s
common stock, par value $0.001 per share (the “Common Stock”), on the terms and conditions set forth in this
Section 3.


 


(a)Conversion
Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be
entitled to convert any portion of the outstanding and unpaid Conversion Amount into fully paid and nonassessable shares of Common
Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of
a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock,
the Company shall round such fraction of a share of Common Stock up or down, as applicable, to the nearest whole share. The Company
shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common
Stock upon conversion of any Conversion Amount.


 




    	- 3 -



    	 



    

 


(b)Conversion
Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall
be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).


 


(i)“Conversion
Amount” means the sum of (A) the portion of the Principal to be converted, redeemed or otherwise with respect to which
this determination is being made and (B) accrued and unpaid Interest with respect to such Principal.


 


(ii)“Conversion
Price” means, as of any Conversion Date or other date of determination, $0.01 per share, subject to adjustment as provided
herein.


 


(c)Mechanics
of Conversion.


 


(i)Optional
Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”),
the Holder shall (A) transmit by facsimile or electronic mail (or otherwise deliver), for receipt on or prior to 11:59 p.m., New
York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion
Notice”) to the Company and (B) if required by Section 3(c)(iii), surrender this Note to a common carrier for delivery
to the 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 the second (2nd) Business Day following the date of receipt of a Conversion
Notice, the Company shall transmit by facsimile or electronic mail a confirmation of receipt of such Conversion Notice to the
Holder and the Transfer Agent. On or before the third (3rd) Trading Day following the date of receipt of a Conversion Notice (the
“Share Delivery Date”), the Company shall (x) provided that the Transfer Agent is participating in the
DTC Fast Automated Securities Transfer Program and the Conversion Shares are subject to an effective registration statement in
favor of the Holder or at a time when Rule 144 would be available for immediate resale of the Conversion Shares by the Holder,
credit such aggregate number of shares of 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 At Custodian system or (y) if the Transfer Agent is not participating
in the DTC Fast Automated Securities Transfer Program or the Conversion Shares are not subject to an effective registration statement
in favor of the Holder or at a time when Rule 144 would not be available for immediate resale of the Conversion Shares by the
Holder, 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 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 five (5) 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
16(d)) representing the outstanding Principal not converted. The Person or Persons entitled to receive the shares of Common Stock
issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common
Stock on the Conversion Date, irrespective of the date such Conversion Shares are credited to the Holder’s account with
DTC or the date of delivery of the certificates evidencing such Conversion Shares, as the case may be.


 




    	- 4 -



    	 



    

 


(ii)Company’s
Failure to Timely Convert. If the Company shall fail on or prior to the Share Delivery Date to issue and deliver a certificate
to the Holder, if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or the shares
of Common Stock to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount are not eligible to
be issued without a restrictive legend pursuant to Section 2(g) of the Securities Purchase Agreement, or credit the Holder’s
balance account with DTC, if the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program and the
shares of Common Stock to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount are eligible
to be issued without a restrictive legend pursuant to Section 2(g) of the Securities Purchase Agreement, for the number of shares
of Common Stock to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount (a “Conversion
Failure”) or on any date of the Company’s obligation to deliver shares of Common Stock as contemplated pursuant
to clause (y) below, then, in addition to all other remedies available to the Holder, (X) 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 and (Y) if on or after such Trading Day the Holder purchases (in an open market transaction
or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that
the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Trading
Days after the Holder’s request and in the Holder’s discretion, either (x) 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 Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to
issue and deliver such certificate or credit the Holder’s balance account with DTC for the shares of Common Stock to which
the Holder is entitled upon the Holder’s conversion of the applicable Conversion Amount shall terminate, or (y) promptly
honor its obligation to deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit
the Holder’s balance account with DTC for such shares of 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 Common Stock, times (B) the Closing Bid Price
of the Common Stock on the Conversion Date. For the purpose of this Section 3(c)(ii), a Mandatory Conversion Date shall also deemed
to be a Share Delivery Date.

(iii)Registration;
Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the names and
addresses of the holders of each Note and the Principal amount of this Note (and stated interest thereon) held by such holders
(the “Registered Notes”). The entries in the Register shall be conclusive and binding for all purposes absent
manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the
owner of a Note for all purposes, including, without limitation, the right to receive payments of Principal and Interest, if any,
hereunder, notwithstanding notice to the contrary. A Registered Note may be assigned or sold in whole or in part only by registration
of such assignment or sale on the Register. Upon its receipt of a request to assign or sell all or part of any Registered Note
by a Holder, the Company shall record the information contained therein in the Register and issue one or more new Registered Notes
in the same aggregate Principal amount as the Principal amount of the surrendered Registered Note to the designated assignee or
transferee pursuant to Section 16. Notwithstanding anything to the contrary in this Section 3(c)(iii) and provided that the Holder
complies with Section 2(f) of the Securities Purchase Agreement, a Holder may assign any Note or any portion thereof to an Affiliate
of such Holder or a Related Fund of such Holder without delivering a request to assign or sell such Note to the Company and the
recordation of such assignment or sale in the Register (a “Related Party Assignment”); provided, that
(x) the Company may continue to deal solely with such assigning or selling Holder unless and until such Holder has delivered a
request to assign or sell such Note or portion thereof to the Company for recordation in the Register; (y) the failure of such
assigning or selling Holder to deliver a request to assign or sell such Note or portion thereof to the Company shall not affect
the legality, validity, or binding effect of such assignment or sale and (z) such assigning or selling Holder shall, acting solely
for this purpose as a non-fiduciary agent of the Company, maintain a register (the “Related Party Register”)
comparable to the Register on behalf of the Company, and any such assignment or sale shall be effective upon recordation of such
assignment or sale in the Related Party Register. 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 reissuance of this Note
upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal and Interest, if
any, 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)Reserved.


 




    	- 6 -



    	 



    

 


(v)Mandatory
Conversion. If at any time from and after the Issuance Date, upon either (A) the Company closing of a Qualified Offering or
(B)(i) the Closing Bid Price of the Common Stock for any twenty (20) Trading Days during any thirty (30) consecutive Trading Days
following the Issuance Date (the “Mandatory Conversion Measuring Period”) equals or exceeds 300% of the Conversion
Price in effect on the Issuance Date (as adjusted for any stock dividend, stock split, stock combination, reclassification or
similar transaction after the Subscription Date) and (ii) no Equity Conditions Failure has occurred during the period from the
applicable Mandatory Conversion Notice Date through the applicable Mandatory Conversion Date (each as defined below), the Company
shall have the right to require the Holder to convert all or any portion of the Conversion Amount then remaining under this Note
(the “Mandatory Conversion Amount”), as designated in the Mandatory Conversion Notice on the Mandatory Conversion
Date (each as defined below) into fully paid, validly issued and nonassessable shares of Common Stock in accordance with Section
3(b) hereof at the Conversion Rate as of the Mandatory Conversion Date (as defined below) (a “Mandatory Conversion”).
The Company may exercise its right to require conversion under this Section 3(c)(v)(A) by delivering within not more than two
(2) Trading Days following the end of such Mandatory Conversion Measuring Period a written notice thereof by facsimile or electronic
mail, and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the “Mandatory
Conversion Notice” and the date all of the holders of this Note and the Other Notes received such notice is referred
to as the “Mandatory Conversion Notice Date”). The Mandatory Conversion Notice shall be irrevocable. The Mandatory
Conversion Notice shall (i) state (a) the Trading Day on which the Mandatory Conversion shall occur, which Trading Day shall not
be less than ten (10) Trading Days nor more than fifteen (15) Trading Days following the Mandatory Conversion Notice Date (the
“Mandatory Conversion Date”), (b) the aggregate Conversion Amount of the Notes which the Company has elected
to be subject to Mandatory Conversion from the Holder and all of the holders of the Other Notes pursuant to this Section 3(c)(v)
(and analogous provisions under the Other Notes), (c) the number of shares of Common Stock to be issued to the Holder on the Mandatory
Conversion Date, (d) the Make-Whole Amount to be paid to the Holder on the Mandatory Conversion Date in cash by wire transfer
of immediately available funds and (e) certify that there has been no Equity Conditions Failure as of the applicable Mandatory
Conversion Notice Date. If the Company confirmed that there was no Equity Conditions Failure as of the applicable Mandatory Conversion
Notice Date but an Equity Conditions Failure occurred between the applicable Mandatory Conversion Notice Date and any time through
the applicable Mandatory Conversion Date (the “Mandatory Conversion Interim Period”), the Company shall provide
the Holder a subsequent notice to that effect. If the Equity Conditions are not satisfied (or waived in writing by the Holder)
during such Mandatory Conversion Interim Period, then the Mandatory Conversion shall be null and void with respect to all or any
part designated by the Holder of the unconverted Mandatory Conversion and the Holder shall be entitled to all the rights of a
holder of this Note with respect to such amount of the Mandatory Conversion Amount. On the Mandatory Conversion Date the Company
shall deliver or shall cause to be delivered to the Holder (1) the number of shares of Common Stock the Holder is entitled to
pursuant to Section 3(b) and (2) deliver to the Holder the Make-Whole Amount in cash by wire transfer of immediately available
funds pursuant to wire instructions provided to the Company by the Holder in writing. Notwithstanding anything to the contrary
in this Section 3(c)(v)(A), until the Mandatory Conversion has occurred, the Mandatory Conversion Amount may be converted, in
whole or in part, by the Holder into shares of Common Stock pursuant to Section 3(c)(i). Notwithstanding the foregoing, the Company
may effect only two (2) Mandatory Conversions during any six (6) month period. All Conversion Amounts converted by the Holder
after the Mandatory Conversion Notice Date shall reduce the Mandatory Conversion Amount of this Note required to be converted
on the Mandatory Conversion Date, unless the Holder otherwise indicates in the applicable Conversion Notice. If the Company elects
to cause a Mandatory Conversion pursuant to Section 3(c)(v), then it must simultaneously take the same action in the same proportion
with respect to the Other Notes.

default or event of default occurs with respect to (1) any of the 6% Amended and Restated Senior Subordinated Secured Convertible
Notes or (2) any of the 15% Senior Subordinated Secured Convertible Notes.


 


(b)Redemption
Right. Upon the occurrence of an Event of Default with respect to this Note or any Other Note, the Company shall within one
(1) Business Day deliver written notice thereof via facsimile or electronic mail and overnight courier (an “Event of
Default Notice”) to the Holder. At any time after the earlier of the Holder’s receipt of an Event of Default Notice
and the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem (an “Event of Default
Redemption”) all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption
Notice”) to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder
is electing to require the Company to redeem. Each portion of this Note subject to redemption by the Company pursuant to this
Section 4(b) shall be redeemed by the Company in cash by wire transfer of immediately available funds pursuant to wire instructions
provided to the Company by the Holder in writing at a price equal to the sum of (1) the greater of (x) 125% of the Conversion
Amount being redeemed and (y) the product of (A) the Conversion Amount being redeemed and (B) the quotient determined by dividing
(I) the greatest Closing Sale Price of the shares of Common Stock during the period beginning on the date immediately preceding
such Event of Default and ending on the date the Holder delivers the Event of Default Redemption Notice, by (II) the lowest Conversion
Price in effect during such period and (2) the Make-Whole Amount (the “Event of Default Redemption Price”).
Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 10. To the extent redemptions
required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the
Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section
4, but subject to Section 3(d), until the Event of Default Redemption Price (together with any interest thereon) is paid in full,
the Conversion Amount submitted for redemption under this Section 4(b) (together with any interest thereon) may be converted,
in whole or in part, by the Holder into Common Stock pursuant to Section 3. The parties hereto agree that in the event of the
Company’s redemption of any portion of the Note under this Section 4(b), the Holder’s damages would be uncertain and
difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability
of a suitable substitute investment opportunity for the Holder. Accordingly, any Event of Default redemption premium due under
this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss
of its investment opportunity and not as a penalty.


 


(5)RIGHTS
UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.


 




    	- 11 -



    	 



    

 


(a)Assumption.
The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of
the obligations of the Company under this Note and the other Transaction Documents. No later than (i) thirty (30) days prior to
the occurrence or consummation of any Fundamental Transaction or (ii) if later, the first Trading Day following the date the Company
first becomes aware of the occurrence or potential occurrence of a Fundamental Transaction, the Company shall deliver written
notice thereof via facsimile or electronic mail and overnight courier to the Holder. Upon the occurrence or consummation of any
Fundamental Transaction the Company and the Successor Entity or Successor Entities, jointly and severally, shall succeed to, and
the Company shall cause any Successor Entity or Successor Entities to jointly and severally succeed to, and be added to the term
“Company” under this Note (so that from and after the date of such Fundamental Transaction, each and every provision
of this Note referring to the “Company” shall refer instead to each of the Company and the Successor Entity or Successor
Entities, jointly and severally), and the Company and the Successor Entity or Successor Entities, jointly and severally, may exercise
every right and power of the Company prior thereto and shall assume all of the obligations of the Company prior thereto under
this Note with the same effect as if the Company and such Successor Entity or Successor Entities, jointly and severally, had been
named as the Company in this Note, and, solely at the request of the Holder, if the Successor Entity and/or Successor Entities
is a publicly traded corporation whose common capital stock is quoted on or listed for trading on an Eligible Market, shall deliver
(in addition to and without limiting any right under this Note) to the Holder in exchange for this Note a security of the Successor
Entity and/or Successor Entities evidenced by a written instrument substantially similar in form and substance to this Note and
convertible for a corresponding number of shares of capital stock of the Successor Entity and/or Successor Entities (the “Successor
Capital Stock”) equivalent (as set forth below) 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 such
security shall be satisfactory to the Holder, and with an identical conversion price to the Conversion Price hereunder (such adjustments
to the number of shares of capital stock and such conversion price being for the purpose of protecting after the consummation
or occurrence of such Fundamental Transaction the economic value of this Note that was in effect immediately prior to the consummation
or occurrence of such Fundamental Transaction, as elected by the Holder solely at its option). Upon occurrence or consummation
of the Fundamental Transaction the Company and the Successor Entity or Successor Entities shall deliver to the Holder confirmation
that there shall be issued upon conversion of this Note at any time after the occurrence or consummation of the Fundamental Transaction,
as elected by the Holder solely at its option, shares of Common Stock, Successor Capital Stock or, in lieu of the shares of Common
Stock or Successor Capital Stock (or other securities, cash, assets or other property purchasable upon the conversion of this
Note prior to such Fundamental Transaction), such shares of stock, securities, cash, assets or any other property whatsoever (including
warrants or other purchase or subscription rights), which for purposes of clarification may continue to be shares of Common Stock,
if any, that the Holder would have been entitled to receive upon the happening of such Fundamental Transaction or the record,
eligibility or other determination date for the event resulting in such Fundamental Transaction, had this Note been converted
immediately prior to such Fundamental Transaction or the record, eligibility or other determination date for the event resulting
in such Fundamental Transaction (without regard to any limitations on the conversion of this Note), as adjusted in accordance
with the provisions of this Note. The provisions of this Section 5(a) shall apply similarly and equally to successive Fundamental
Transactions.


 




    	- 12 -



    	 



    

 


(b)Redemption
Right. No sooner than twenty-five (25) days nor later than twenty (20) days prior to the consummation of a Change of Control,
but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile
or electronic mail and overnight courier to the Holder (a “Change of Control Notice”). At any time during
the period beginning on the earlier to occur of (x) any oral or written agreement by the Company or any of its Subsidiaries, upon
consummation of which the transaction contemplated thereby would reasonably be expected to result in a Change of Control, (y)
the Holder becoming aware of a Change of Control and (z) the Holder’s receipt of a Change of Control Notice and ending twenty-five
(25) Trading Days after the date of the consummation of such Change of Control, the Holder may require the Company to redeem (a
“Change of Control Redemption”) 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 require the Company to redeem. The portion of this Note subject to redemption pursuant to this
Section 5(b) shall be redeemed by the Company in cash by wire transfer of immediately available funds pursuant to wire instructions
provided to the Company by the Holder in writing at a price equal to the greater of (x) 125% of the Conversion Amount being redeemed
and (y) the product of (A) the Conversion Amount being redeemed and (B) the quotient determined by dividing (I) the greatest Closing
Sale Price of the shares of Common Stock during the period beginning on the date immediately preceding the earlier to occur of
(x) the consummation of the Change of Control and (y) the public announcement of such Change of Control and ending on the date
the Holder delivers the Change of Control Redemption Notice, by (II) the lowest Conversion Price in effect during such period
(the “Change of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance
with the provisions of Section 10 and shall have priority to payments to shareholders in connection with a Change of Control.
To the extent redemptions required by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments
of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary
in this Section 5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any interest thereon)
is paid in full, the Conversion Amount submitted for redemption under this Section 5(b) (together with any interest thereon) may
be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. The parties hereto agree that in the
event of the Company’s redemption of any portion of the Note under this Section 5(b), the Holder’s damages would be
uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty
of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any Change of Control redemption
premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s
actual loss of its investment opportunity and not as a penalty.


 


(6)CORPORATE
EVENTS. In addition to and not in substitution for any other rights hereunder, prior to the occurrence or consummation of
any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities, cash, assets
or other property with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company
shall make appropriate provision to insure that, and any applicable Successor Entity or Successor Entities shall ensure that the
Holder will thereafter have the right to receive upon conversion of this Note at any time after the occurrence or consummation
of the Corporate Event, shares of Common Stock or Successor Capital Stock or, if so elected by the Holder, in lieu of the shares
of Common Stock (or other securities, cash, assets or other property) purchasable upon the conversion of this Note prior to such
Corporate Event, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other
purchase or subscription rights and any shares of Common Stock) which the Holder would have been entitled to receive upon the
occurrence or consummation of such Corporate Event or the record, eligibility or other determination date for the event resulting
in such Corporate Event, had this Note been converted immediately prior to such Corporate Event or the record, eligibility or
other determination date for the event resulting in such Corporate Event (without regard to any limitations on conversion of this
Note). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required
Holders. The provisions of this Section 6 shall apply similarly and equally to successive Corporate Events.

(7)RIGHTS
UPON ISSUANCE OF OTHER SECURITIES.


 


(a)Adjustment
of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date, 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 deemed
to have been issued or sold by the Company in connection with any Excluded Securities) for a consideration per share (the “New
Issuance Price”) less than a price (the “Applicable Price”) equal to the Conversion Price in effect
immediately prior to such issue or sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then
immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance
Price. 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 any such Option is less than the Applicable Price, 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 Options 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 upon granting or sale of the Option, upon exercise of the Option and upon
conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option less any consideration paid
or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such Option, upon exercise
of such Option and upon conversion exercise or exchange 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 shares of Common Stock or of such Convertible
Securities upon the exercise of such Options or upon the actual issuance of such shares of 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 the conversion or exchange or exercise thereof is less than the Applicable
Price, 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 or sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii),
the “lowest price per share for which one share of Common Stock is issuable upon the conversion or exchange or exercise
thereof” 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 upon the issuance or sale of the Convertible Security and upon the conversion or
exchange or exercise of such Convertible Security less any consideration paid or payable by the Company with respect to such one
share of Common Stock upon the issuance or sale of the Convertible Security and 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 shares
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 has been or is 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.


 




    	- 14 -



    	 



    

 


(iii)Change
in Option Price or Rate of Conversion. Except for Excluded Securities, 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 shares of Common Stock
increases or decreases at any time, the Conversion Price in effect at the time of such increase or decrease 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
increased or decreased purchase price, additional consideration or increased or decreased 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 increased or decreased in the manner described in the immediately
preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion
or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to
this Section 7(a) shall be made 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, (x) the Options will be deemed to have been issued for the Option Value of such
Options and (y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued or sold
for the difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company
pursuant to the terms of such other securities of the Company, less (II) the Option Value. If any shares of Common Stock, Options
or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration other than cash
received therefor will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock, Options
or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by
the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities,
in which case the amount of consideration received by the Company will be the Closing Sale Price of such publicly traded securities
on the date of receipt of such publicly traded securities. If any shares of Common Stock, Options or Convertible Securities are
issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the
amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving
entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be. The fair value
of any consideration other than cash or publicly traded securities will be determined jointly by the Company and the Required
Holders. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation
(the “Valuation Event”), the fair value of such consideration will be determined within five (5) Business Days
after the tenth (10th) day following the Valuation Event by an independent, reputable appraiser jointly selected by
the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties absent manifest
error and the fees and expenses of such appraiser shall be equally borne by the Company and such holders of Notes that dispute
the Company’s fair value valuation.


 




    	- 15 -



    	 



    

 


(v)Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for
or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of
the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the
making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.


 


(vi)No
Readjustments. For the avoidance of doubt, in the event the Conversion Price has been adjusted pursuant to this Section 7(a)
and the Dilutive Issuance that triggered such adjustment does not occur, is not consummated, is unwound or is cancelled after
the facts for any reason whatsoever, in no event shall the Conversion Price be readjusted to the Conversion Price that would have
been in effect if such Dilutive Issuance had not occurred or been consummated.


 


(b)Adjustment
of Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription
Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares
of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be
proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock
split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion
Price in effect immediately prior to such combination will be proportionately increased.


 




    	- 16 -



    	 



    

 


(c)Other
Events. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by
such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights
with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Conversion Price
so as to protect the rights of the Holder under this Note; provided, that no such adjustment will increase the Conversion
Price as otherwise determined pursuant to this Section 7.


 


(d)Voluntary
Adjustment by Company. The Company may at any time during the term of this Note, with the prior written consent of the Required
Holders, reduce the then current Conversion Price to any amount and for any period of time deemed appropriate by the Board of
Directors of the Company.


 


(8)NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation, Bylaws or through
any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities,
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will
at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the
rights of the Holder of this Note.


 


(9)RESERVATION
OF AUTHORIZED SHARES.


 


(a)Reservation.
Following the date that is ninety (90) days from the Issuance Date, the Company shall reserve out of its authorized and unissued
shares of Common Stock a number of shares of Common Stock for each of this Note equal to 120% of the Conversion Rate with respect
to the Conversion Amount of each such Note as of the Issuance Date. So long as any of this Note is outstanding, the Company
shall take all action necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the
purpose of effecting the conversion of this Note, the number of shares of Common Stock specified above in this Section 9(a) as
shall from time to time be necessary to effect the conversion of all of this Note; provided that, subject to this Section
9(a), at no time shall the number of shares of Common Stock so reserved be less than the number of shares required to be reserved
pursuant hereto (in each case, without regard to any limitations on conversions) (the “Required Reserve Amount”).


 


(b)Insufficient
Authorized Shares. If at any time following the date that is ninety (90) days from the Issuance Date while any of the Notes
remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy
its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required
Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary
to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the
Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as
practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than seventy-five (75) days
after the occurrence of such Authorized Share Failure, the Company shall either (x) obtain the written consent of its shareholders
for the approval of an increase in the number of authorized shares of Common Stock and provide each shareholder with an information
statement with respect thereto or (y) hold a meeting of its shareholders for the approval of an increase in the number of authorized
shares of Common Stock. In connection with such meeting, the Company shall provide each shareholder with a proxy statement and
shall use its best efforts to solicit its shareholders’ approval of such increase in authorized shares of Common Stock and
to cause its Board of Directors to recommend to the shareholders that they approve such proposal. Notwithstanding the foregoing,
if during any such time of an Authorized Share Failure, the Company is able to obtain the written consent of a majority of the
shares of its issued and outstanding Common Stock to approve the increase in the number of authorized shares of Common Stock,
the Company may satisfy this obligation by obtaining such consent and submitting for filing with the SEC an Information Statement
on Schedule 14C. In the event that upon any conversion of this Note, the Company does not have sufficient authorized shares to
deliver in satisfaction of such conversion, then the Holder may elect to void such attempted conversion.

(10)REDEMPTIONS.


 


(a)Mechanics.
The Company shall deliver the applicable Event of Default Redemption Price to the Holder within three (3) Business Days after
the Company’s receipt of the Holder’s Event of Default Redemption Notice (the “Event of Default Redemption
Date”). If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company
shall deliver the applicable Change of Control Redemption Price to the Holder (i) concurrently with the consummation of such Change
of Control if such notice is received prior to the consummation of such Change of Control and (ii) within three (3) Business Days
after the Company’s receipt of such notice otherwise (such date, the “Change of Control Redemption Date”).
The Company shall pay the applicable Redemption Price to the Holder in cash by wire transfer of immediately available funds pursuant
to wire instruction provided by the holder in writing to the Company on the applicable due date. In the event of a redemption
of less than all of the Conversion Amount of this Note, if requested by the Holder and upon delivery by the Holder to the Company
of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section
16(d)) representing the outstanding Principal which has not been redeemed and any accrued Interest on such Principal which shall
be calculated as if no Redemption Notice has been delivered. In the event that the Company does not pay the applicable Redemption
Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption
Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder
all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable
Redemption Price has not been paid. Upon the Company’s receipt of such notice, (x) the applicable Redemption Notice shall
be null and void with respect to such Conversion Amount, (y) the Company shall immediately return this Note, or issue a new Note
(in accordance with Section 16(d)) to the Holder representing such Conversion Amount to be redeemed and (z) the Conversion Price
of this Note or such new Notes shall be adjusted to the lesser of (A) the Conversion Price as in effect on the date on which the
applicable Redemption Notice is voided and (B) the lowest Closing Bid Price of the Common Stock during the period beginning on
and including the date on which the applicable Redemption Notice is delivered to the Company and ending on and including the date
on which the applicable Redemption Notice is voided.

the validity of the remaining provisions of this Note so long as this Note as so modified continues to express, without material
change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability
of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties
or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in
good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect
of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).
