SENIOR SUBORDINATED CONVERTIBLE NOTE 

 

			
	Issuance Date: January —, 2022	  	Original Principal Amount: U.S. $_________

 FOR VALUE RECEIVED, Heart Test Laboratories, Inc. (d/b/a HeartSciences), a Texas corporation (the
“Company”), hereby promises to pay to the order of __________________or its registered assigns (“Holder”) the amount set forth 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, or upon 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 (as defined below) from the date set forth above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable,
whether upon the Maturity Date or upon acceleration, conversion, redemption or otherwise (in 












 
each case in accordance with the terms hereof). This Senior Subordinated Convertible Note (including all Senior Subordinated Convertible Notes issued in exchange, transfer or replacement hereof,
this “Note”) is one of an issue of Senior Subordinated Convertible Notes issued pursuant to the Securities Purchase Agreement, dated as of December 22, 2021 (the “Subscription Date”), by and among the Company
and the investors (the “Buyers”) referred to therein, as amended from time to time (collectively, the “Notes”, and such other Senior Subordinated Convertible Notes, the “Other Notes”).
Certain capitalized terms used herein are defined in Section 33. 
 1. PAYMENTS OF PRINCIPAL. On the Maturity Date, the Company
shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest and accrued and unpaid Late Charges (as defined in Section 26(c)) on such Principal and Interest. Other than as specifically permitted
by this Note, the Company may not prepay any portion of the outstanding Principal, accrued and unpaid Interest or accrued and unpaid Late Charges on Principal and Interest, if any. 

2. INTEREST; INTEREST RATE. 

(a) Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year and twelve 30-day months and shall compound annually. Interest shall be paid on the Maturity Date in cash. 

(b) 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 on each Conversion Date in accordance with Section 3(b)(i) or upon any redemption in accordance with Section 11 or any required payment upon any Bankruptcy Event
of Default. From and after the occurrence and during the continuance of any Event of Default, the Interest Rate shall automatically be increased to thirteen percent (13.0%) per annum (the “Default Rate”). In the event that such
Event of Default is subsequently cured (and no other Event of Default then exists, including, without limitation, for the Company’s failure to pay such Interest at the Default Rate on the Maturity Date), the adjustment referred to in the
preceding sentence shall cease to be effective as of the calendar day immediately following 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 such cure of such Event of Default. 

3. CONVERSION OF NOTES. At any time after the Issuance Date, this Note shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock (as defined below), 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 (as defined below) into validly issued, fully paid and non-assessable 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


  
 2 













 
of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp,
issuance and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent (as defined below)) that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any
Conversion Amount. 
 (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 (x) portion of the Principal to be converted, redeemed or
otherwise with respect to which this determination is being made and (y) all accrued and unpaid Interest with respect to such portion of the Principal amount and accrued and unpaid Late Charges with respect to such portion of such Principal and
such Interest, if any. 
 (ii) “Conversion Price” means, as of any Conversion Date or other date of
determination, $0.1835, 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 deliver (whether via electronic mail or otherwise), 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
(each, a “Conversion Notice”) to the Company. If required by Section 3(c)(iii), within two (2) Trading Days following a conversion of this Note as aforesaid, the Holder shall surrender this Note to a nationally recognized
overnight delivery service for delivery to the Company (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction as contemplated by Section 20(b)). On or before the first (1st) Trading Day
following the date of receipt of a Conversion Notice, the Company shall transmit by electronic mail an acknowledgment, in the form attached hereto as Exhibit II, of confirmation of receipt of such Conversion Notice and representation as to
whether such shares of Common Stock may then be resold pursuant to Rule 144 or an effective and available registration statement (each, an “Acknowledgement”) to the Holder and, if after the Public Company Date, to the Company’s
transfer agent (the “Transfer Agent”) which confirmation shall constitute an instruction to the Company and, if after the Public Company Date, to the Transfer Agent to process such Conversion Notice in accordance with the terms
herein. On or before the second (2nd) Trading Day following the date on which the Company has received a Conversion Notice (or such earlier date as required pursuant to the 1934 Act or other applicable law, rule or regulation for the settlement of a
trade initiated on the applicable Conversion Date of such shares of Common Stock issuable pursuant to such Conversion Notice) (the “Share Delivery Deadline”), the Company shall (1) if on or after the Public Company Date,
provided 

  
 3 













 
that the Transfer Agent is participating in The Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program (“FAST”), credit such
aggregate number of shares of Common Stock to which the Holder shall be entitled pursuant to such conversion to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (2) if
either (x) prior to the Public Company Date or (y) on or after the Public Company Date if the Transfer Agent is not participating in FAST, upon the request of the Holder, issue and deliver (via reputable overnight courier) 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 pursuant to such conversion. If this Note is physically
surrendered for conversion pursuant to 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 two (2) Business Days after receipt of this Note and at its own expense, issue and deliver to the Holder (or its designee) a new Note (in accordance with Section 20(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. Notwithstanding
anything to the contrary contained in this Note or the Registration Rights Agreement, after the effective date of the Registration Statement (as defined in the Registration Rights Agreement) and prior to the Holder’s receipt of the notice of a
Grace Period (as defined in the Registration Rights Agreement), the Company shall cause the Transfer Agent to deliver unlegended shares of Common Stock to the Holder (or its designee) in connection with any sale of Registrable Securities (as defined
in the Registration Rights Agreement) with respect to which the Holder has entered into a contract for sale, and delivered a copy of the prospectus included as part of the particular Registration Statement to the extent applicable, and for which the
Holder has not yet settled. 
 (ii) Company’s Failure to Timely Convert. 

(1) General. The Company shall in all cases use its reasonable best efforts to comply with the delivery requirements set
forth herein and shall do all things and take all actions reasonably requested by the Holder in furtherance thereof. 
 (2)
Conversion Failures On or After the Public Company Date. If on or after the Public Company Date the Company shall fail, for any reason or for no reason, on or prior to the applicable Share Delivery Deadline, either (I) if the Transfer
Agent is not participating in FAST, to issue and deliver to the Holder (or its designee) a certificate for the number of shares of Common Stock to which the Holder is entitled and register such shares of Common Stock on the Company’s share
register or, if the Transfer Agent is participating in FAST, to credit the balance account of the Holder or the Holder’s designee with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s
conversion of this Note (as the case may be) or (II) if the Registration Statement covering the resale of the shares of Common Stock that are the subject of the Conversion Notice (the “Unavailable Conversion Shares”) is not
available for the resale of such Unavailable Conversion 

  
 4 













 
Shares and the Company fails to promptly, but in no event later than as required pursuant to the Registration Rights Agreement (x) so notify the Holder and (y) deliver the shares of
Common Stock electronically without any restrictive legend by crediting such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such conversion to the Holder’s or its designee’s balance account with DTC
through its Deposit/Withdrawal At Custodian system (the event described in the immediately foregoing clause (II) is hereinafter referred as a “Notice Failure” and together with the event described in clause (I) above, a
“Conversion Failure”), then, in addition to all other remedies available to the Holder, (1) the Company shall pay in cash to the Holder on each day after such Share Delivery Deadline that the issuance of such shares of Common
Stock is not timely effected an amount equal to 2% of the product of (A) the sum of the number of shares of Common Stock not issued to the Holder on or prior to the Share Delivery Deadline and to which the Holder is entitled, multiplied by
(B) any trading price of the Common Stock selected by the Holder in writing as in effect at any time during the period beginning on the applicable Conversion Date and ending on the applicable Share Delivery Deadline and (2) the Holder,
upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned (as the case may be) any portion of this Note that has not been converted pursuant to such Conversion Notice, provided that the voiding
of a Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In addition to the foregoing, if on or after the
Public Company Date and on or prior to the applicable Share Delivery Deadline either (A) if the Transfer Agent is not participating in FAST, the Company shall fail to issue and deliver to the Holder (or its designee) a certificate and register
such shares of Common Stock on the Company’s share register or, if the Transfer Agent is participating in FAST, the Transfer Agent shall fail to credit the balance account of the Holder or the Holder’s designee with DTC for the number of
shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder or pursuant to the Company’s obligation pursuant to clause (II) below or (B) a Notice Failure occurs, and if on or after such Share
Delivery Deadline the Holder acquires (in an open market transaction, a stock loan or otherwise) shares of Common Stock corresponding to all or any portion of the number of shares of Common Stock issuable upon such conversion that the Holder is
entitled to receive from the Company and has not received from the Company in connection with such Conversion Failure or Notice Failure, as applicable (a “Buy-In”), then, in addition to all other remedies available to the Holder,
the Company shall, within two (2) Business Days after receipt of the Holder’s request and in the Holder’s discretion, either: (I) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including
brokerage commissions, stock loan costs and other out-of-pocket expenses, if any) for the shares of Common Stock so acquired (including, without limitation, by any other
Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate (and to issue such shares of Common
Stock) or credit the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be)
(and to issue such shares of Common Stock) shall 

  
 5 













 
terminate, or (II) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit the balance account of
such Holder or such Holder’s designee, as applicable, with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) and pay cash to the Holder in an amount
equal to the excess (if any) of the Buy-In Price over the product of (x) such number of shares of Common Stock multiplied by (y) the lowest Closing Sale Price of the Common Stock on any Trading Day
during the period commencing on the date of the applicable Conversion Notice and ending on the date of such issuance and payment under this clause (II) (the “Buy-In Payment Amount”). Nothing
shall limit the 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 the Company’s failure to
timely deliver certificates representing shares of Common Stock (or to electronically deliver such shares of Common Stock) upon the conversion of this Note as required pursuant to the terms hereof. 

(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 the Notes 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 hereunder) notwithstanding notice to the contrary. A Registered Note may be assigned, transferred or sold in whole or in part only by registration of such assignment or sale on the Register. Upon its receipt of a written request to assign,
transfer or sell all or part of any Registered Note by the holder thereof, 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 20, provided that if the Company does not so record an assignment, transfer or sale (as the case may be) of all or part of any Registered
Note within two (2) Business Days of such a request, then the Register shall be automatically deemed updated to reflect such assignment, transfer or sale (as the case may be). Notwithstanding anything to the contrary in this
Section 3(c)(iii), the 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


  
 6 













 
Related Party Register. Notwithstanding anything to the contrary set forth in this Section 3, following 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 (in which event this Note shall be delivered to the Company following conversion thereof as
contemplated by Section 3(c)(i)) 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, Interest and Late Charges converted and/or paid (as the case may be) and the dates of such conversions and/or payments (as the case may be) 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. If the Company does not update the Register to record such Principal, Interest and Late Charges converted and/or paid (as the case may
be) and the dates of such conversions and/or payments (as the case may be) within two (2) Business Days of such occurrence, then the Register shall be automatically deemed updated to reflect such occurrence. 

(iv) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder
of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes
converted on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of
all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of
Common Stock not in dispute and resolve such dispute in accordance with Section 25. 
 (d) Limitations on
Conversions. From and after the Public Company Date, the Company shall not effect the conversion of any portion of this Note, and the Holder shall not have the right to convert any portion of this Note pursuant to the terms and conditions of
this Note and any such conversion shall be null and void and treated as if never made, to the extent that after giving effect to such conversion, the Holder together with the other Attribution Parties collectively would beneficially own in excess of
4.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned
by the Holder and the other Attribution Parties shall include the number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon conversion of this Note with respect to
which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of the
other Attribution Parties and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, 

  
 7 













 
without limitation, any convertible notes or convertible preferred stock or warrants, including, without limitation, the Warrants) beneficially owned by the Holder or any other Attribution Party
subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 3(d). For purposes of this Section 3(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934
Act. For purposes of determining the number of outstanding shares of Common Stock the Holder may acquire upon the conversion of this Note without exceeding the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common
Stock as reflected in (x) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the SEC, as the case may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company or the Transfer Agent, if any, setting forth
the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). From and after the Public Company Date, if the Company receives a Conversion Notice from the Holder at a time when the actual number of
outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Conversion Notice would
otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 3(d), to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of shares of Common Stock to be purchased pursuant to
such Conversion Notice. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common
Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder and any other Attribution
Party since the date as of which the Reported Outstanding Share Number was reported. From and after the Public Company Date, in the event that the issuance of shares of Common Stock to the Holder upon conversion of this Note results in the Holder
and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares
so issued by which the Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab initio, and the
Holder shall not have the power to vote or to transfer the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time to time increase (with such increase not effective until the sixty-first (61st) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified in such notice; provided that (i) any such increase in the
Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder
and the other Attribution Parties and not to any other holder of Notes that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Note in excess of the Maximum
Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to convert this Note
pursuant to this paragraph shall have any 

  
 8 













 
effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of convertibility. The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 3(d) to the extent necessary to correct this paragraph (or any portion of this paragraph) which may be defective or inconsistent with the intended beneficial
ownership limitation contained in this Section 3(d) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor
holder of this Note. 
 (e) Right of Alternate Conversion Upon an Event of Default. 

(i) General. Subject to Section 3(d), at any time after the Public Company Date and during an Event of Default
Redemption Right Period (as defined below) with respect to an Event of Default (regardless of whether such Event of Default has been cured or if the Holder has delivered an Event of Default Redemption Notice to the Company), the Holder may, at the
Holder’s option, convert (each, an “Alternate Conversion”, and the date of such Alternate Conversion, each, an “Alternate Conversion Date”) all, or any part of, the Conversion Amount (such portion of the
Conversion Amount subject to such Alternate Conversion, the “Alternate Conversion Amount”) into shares of Common Stock at the Alternate Conversion Price. 

(ii) Mechanics of Alternate Conversion. On any Alternate Conversion Date, the Holder may voluntarily convert any
Alternate Conversion Amount pursuant to Section 3(c) (with “Alternate Conversion Price” replacing “Conversion Price” for all purposes hereunder with respect to such Alternate Conversion and with “Redemption Premium of
the Conversion Amount” replacing “Conversion Amount” in clause (x) of the definition of Conversion Rate above with respect to such Alternate Conversion) by designating in the Conversion Notice delivered pursuant to this
Section 3(e) of this Note that the Holder is electing to use the Alternate Conversion Price for such conversion. Notwithstanding anything to the contrary in this Section 3(e), but subject to Section 3(d), until the Company delivers
shares of Common Stock representing the applicable Alternate Conversion Amount to the Holder, such Alternate Conversion Amount may be converted by the Holder into shares of Common Stock pursuant to Section 3(c) without regard to this
Section 3(e). 
 (f) Automatic Conversion. If (x) a Public Company Date occurs, (y) a Qualified
Offering occurs, and (z) no Equity Conditions Failure then exists (collectively, the “Automatic Conversion Conditions”, and the second (2nd) Trading Day (or such later date
as mutually agreed to by the Company and the Holder) after all such Automatic Conversion Conditions are met, the “Automatic Conversion Date”), this Note shall convert into shares of Common Stock in accordance with Section 3(c)
hereof at the Conversion Rate as of the Automatic Conversion Date (giving effect to any adjustment under Section 7(g) hereof) (a “Automatic Conversion”) as if the Holder delivered a Conversion Notice for the entire Conversion
Amount then outstanding on the second (2nd) Trading Day immediately prior to the Automatic Conversion Date; provided, that if the 

  
 9 













 
aggregate number of shares of Common Stock to be received by the Holder in the Automatic Conversion would result in a violation Section 3(d), in lieu of the delivery of such Excess Shares,
the Holder shall receive a right (a “Right”) to receive such Excess Shares as Pre-Funded Warrants. At least two (2) Trading Days prior to the Automatic Conversion Date (the
“Automatic Conversion Notice Date”), the Company shall deliver a written notice to the Holder setting forth (i) the Trading Day selected for the Automatic Conversion in accordance with this Section 3(f), (ii) the aggregate
Conversion Amount, of the Notes subject to Automatic Conversion from the Holder and all of the holders of the Notes pursuant to this Section 3(f) (and analogous provisions under the Other Notes)(the “Automatic Conversion
Amount”), (iii) the number of shares of Common Stock to be issued to the Holder on the Automatic Conversion Date and (iv) a certification that all Automatic Conversion Conditions have been satisfied. Notwithstanding anything herein to
the contrary, if on or prior to the Automatic Conversion Date any of the Automatic Conversion Conditions are not satisfied, (A) the Company shall provide the Holder a subsequent notice to that effect and (B) unless the Holder waives the
applicable failure, the Automatic Conversion shall be cancelled and shall not occur. Notwithstanding the foregoing, any Conversion Amount subject to an Automatic Conversion may be converted by the Holder hereunder prior to the Automatic Conversion
Date and such aggregate Conversion Amount converted hereunder on or after the Automatic Conversion Notice Date and prior to such Automatic Conversion Date shall reduce the Automatic Conversion Amount to be converted on such Automatic Conversion
Date. For the avoidance of doubt, the Company shall have no right to effect a Automatic Conversion if any Event of Default has occurred and continuing, but any Event of Default shall have no effect upon the Holder’s right to convert this Note
in its discretion. 
 4. RIGHTS UPON EVENT OF DEFAULT. 

(a) Event of Default. Each of the following events shall constitute an “Event of Default” and each of
the events in clauses (ix), (x) and (xi) shall constitute a “Bankruptcy Event of Default”: 
 (i) the
failure of the applicable Registration Statement (as defined in the Registration Rights Agreement) to be filed with the SEC on or prior to the date that is five (5) days after the applicable Filing Deadline (as defined in the Registration
Rights Agreement) or the failure of the applicable Registration Statement to be declared effective by the SEC on or prior to the date that is five (5) days after the applicable Effectiveness Deadline (as defined in the Registration Rights
Agreement); 
 (ii) while the applicable Registration Statement is required to be maintained effective pursuant to the terms
of the Registration Rights Agreement, the effectiveness of the applicable Registration Statement lapses for any reason (including, without limitation, the issuance of a stop order) or such Registration Statement (or the prospectus contained therein)
is unavailable to any holder of Registrable Securities (as defined in the Registration Rights Agreement) for sale of all of such holder’s Registrable Securities in accordance with the terms of the Registration Rights Agreement, and such lapse
or unavailability continues for a period of ten (10) consecutive Trading Days or for more than an aggregate of twenty (20) Trading Days in any 365-day period (excluding days during an Allowable Grace
Period (as defined in the Registration Rights Agreement)); 

  
 10 













 (iii) from and after the Public Company Date, the suspension from trading or
the failure of the Common Stock to be trading or listed (as applicable) on an Eligible Market for a period of five (5) consecutive Trading Days; 

(iv) (A) from and after the Public Company Date, the Company’s failure to cure a Conversion Failure or a Delivery Failure
(as defined in the Warrants) by delivery of the required number of shares of Common Stock within five (5) Trading Days after the applicable Conversion Date or exercise date (as the case may be) or (B) the Company’s notice, written or
oral, to any holder of the Notes or Warrants, including, without limitation, by way of public announcement or through any of its agents, at any time, of its intention not to comply, as required, with a request for conversion of any Notes into shares
of Common Stock that is requested in accordance with the provisions of the Notes, other than pursuant to Section 3(d), or a request for exercise of any Warrants for shares of Common Stock in accordance with the provisions of the Warrants; 

(v) except to the extent the Company is in compliance with Section 10(b) below, at any time following the tenth (10th) consecutive day that the Holder’s Authorized Share Allocation (as defined in Section 10(a) below) is less than the sum of (A) the number of shares of Common Stock that the Holder
would be entitled to receive upon a conversion of the full Conversion Amount of this Note (without regard to any limitations on conversion set forth in Section 3(d) or otherwise), and (B) the number of shares of Common Stock that the
Holder would be entitled to receive upon exercise in full of the Holder’s Warrants (without regard to any limitations on exercise set forth in the Warrants); 

(vi) the Company’s or any Subsidiary’s failure to pay to the Holder any amount of Principal, Interest, Late Charges

any such failure remains uncured for at least five (5) days;

part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree, order, judgment or other similar document or any such other decree, order, judgment or other similar document unstayed and in

thirty (30) days after the expiration of such stay; provided, however, any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $250,000 amount set forth above so long as the
Company provides the Holder a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company
or such Subsidiary (as the case may be) will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment; 

(xiii) the Company and/or any Subsidiary, individually or in the aggregate, either (i) fails to pay, when due, or within

assets, operations (including results thereof), liabilities, properties, condition (including financial condition) or prospects of the Company or any of its Subsidiaries, individually or in the aggregate; provided, that with respect to this part
(ii), the Company shall have ten (10) Trading Days to cure any such circumstances or event upon the earlier of (A) receipt of written notice thereof from the Holder, and (B) date on which an officer of the Company has actual knowledge
thereof. 
 (xiv) other than as specifically set forth in another clause of this Section 4(a), the Company or any
Subsidiary breaches any representation or warranty in any material respect (other than the representations or warranties subject to material adverse effect on materiality limitation, which may not be breached in any respect) or any covenant or other
term or condition of any Transaction Document, except, in the case of a breach of a covenant or other term or condition that is curable, only if such breach remains uncured for a period of five (5) consecutive Trading Days; 

(xv) a false or inaccurate certification (including a false or inaccurate deemed certification) by the Company that either
(A) the Equity Conditions are satisfied, (B) there has been no Equity Conditions Failure, or (C) as to whether any Event of Default has occurred; 

(xvi) any breach or failure in any respect by the Company or any Subsidiary to comply with any provision of Section 13 or
14 of this Note; 

  
 13 













 (xvii) any Material Adverse Effect (as defined in the Securities Purchase
Agreement) occurs; 
 (xviii) any provision of any Transaction Document (including, without limitation, the Security
Documents) shall at any time for any reason (other than pursuant to the express terms thereof) cease to be valid and binding on or enforceable against the parties thereto, or the validity or enforceability thereof shall be contested by any party
thereto, or a proceeding shall be commenced by the Company or any Subsidiary or any governmental authority having jurisdiction over any of them, seeking to establish the invalidity or unenforceability thereof, or the Company or any Subsidiary shall

(xix) any Security Document shall for any reason fail or cease to create a separate valid and perfected (other than by action
or inaction of the holder of the Note after written notice by the Company of such failure) for a period exceeding ten (10) days, or any material provision of any Security Document shall at any time for any reason cease to be valid and binding
on or enforceable against the Company or the validity or enforceability thereof shall be contested by any party thereto, or a proceeding shall be commenced by the Company or any governmental authority having jurisdiction over the Company, seeking to
establish the invalidity or unenforceability thereof; any material damage to, or loss, theft or destruction of, any Collateral, whether or not insured, or any strike, lockout, labor dispute, embargo, condemnation, act of God or public enemy, or
other casualty which causes, for more than fifteen (15) consecutive days, the cessation or substantial curtailment of revenue producing activities at any facility of the Company or any Subsidiary, if any such event or circumstance could have a
Material Adverse Effect; or 
 (xx) any Event of Default (as defined in the Other Notes) occurs with respect to any Other
Notes. 
 (b) Notice of an Event of Default; 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 electronic mail and overnight courier (with next day delivery specified) (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 (such earlier date, the “Event of Default Right Commencement Date”) and ending
(such ending date, the “Event of Default Right Expiration Date”, and each such period, an “Event of Default Redemption Right Period”) on the twentieth (20th)
Trading Day after the later of (x) the date such Event of Default is cured and (y) the Holder’s receipt of an Event of Default Notice that includes (I) a reasonable description of the applicable Event of Default, (II) a
certification as to whether, in the opinion of the Company, such Event of Default is capable of being cured and, if applicable, a reasonable description of any existing plans of the Company to cure 

  
 14 













 
such Event of Default and (III) a certification as to the date the Event of Default occurred and, if cured on or prior to the date of such Event of Default Notice, the applicable Event of
Default Right Expiration Date, the Holder may require the Company to redeem (regardless of whether such Event of Default has been cured on or prior to the Event of Default Right Expiration Date) 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 redeem. Each portion of this Note subject to
redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the product of (A) the Conversion Amount to be redeemed multiplied by (B) the Redemption Premium and
(ii) solely if the Public Company Date has occurred, the product of (X) the Conversion Rate with respect to the Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice multiplied by
(Y) the product of (1) the Redemption Premium multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date immediately preceding such Event of Default and ending on
the date the Company makes the entire payment required to be made under this Section 4(b) (the “Event of Default Redemption Price”). Redemptions required by this Section 4(b) shall be made in accordance with the
provisions of Section 11. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary
prepayments. Notwithstanding anything to the contrary in this Section 3(e)(ii), but subject to Section 3(d), until the Event of Default Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount
submitted for redemption under this Section 4(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to the terms of this Note. In the event of the Company’s redemption
of any portion of this 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 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. Any redemption upon an Event of Default shall not constitute an election of remedies by the Holder, and all other rights and remedies of the Holder shall be preserved. 

(c) Mandatory Redemption upon Bankruptcy Event of Default. Notwithstanding anything to the contrary herein, and
notwithstanding any conversion that is then required or in process, upon any Bankruptcy Event of Default, whether occurring prior to or following the Maturity Date, the Company shall immediately pay to the Holder an amount in cash representing
(i) all outstanding Principal, accrued and unpaid Interest and accrued and unpaid Late Charges on such Principal and Interest, multiplied by (ii) the Redemption Premium, in addition to any and all other amounts due hereunder, without the
requirement for any notice or demand or other action by the Holder or any other person or entity, provided that the Holder may, in its sole discretion, waive such right to receive payment upon a Bankruptcy Event of Default, in whole or in part, and
any such waiver shall not affect any other rights of the Holder hereunder, including any other rights in respect of such Bankruptcy Event of Default, any right to conversion, and any right to payment of the Event of Default Redemption Price or any
other Redemption Price, as applicable.

 5. RIGHTS UPON FUNDAMENTAL TRANSACTION. 

(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 in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance satisfactory to the Holder
and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written instrument substantially similar in form
and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts then outstanding and the interest rates of the Notes held by such holder, having similar conversion rights as the
Notes and having similar ranking and security to the Notes, and satisfactory to the Holder. Upon the occurrence of any 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 the Company and shall assume all of
the obligations of the Company under this Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of a Fundamental Transaction, the Successor Entity shall
deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of such Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or
other property (except such items still issuable under Sections 6 and 17, which shall continue to be receivable thereafter)) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the common
stock (or their equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately prior to such
Fundamental Transaction (without regard to any limitations on the conversion of this Note), as adjusted in accordance with the provisions of this Note. Notwithstanding the foregoing, the Holder may elect, at its sole option, by delivery of written
notice to the Company to waive this Section 5(a) to permit the Fundamental Transaction without the assumption of this Note. The provisions of this Section 5 shall apply similarly and equally to successive Fundamental Transactions and shall
be applied without regard to any limitations on the conversion of this Note. 
 (b) Notice of a Change of Control;
Redemption Right. No sooner than twenty (20) Trading Days nor later than ten (10) Trading Days prior to the consummation of a Change of Control (the “Change of Control Date”), 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 after
the Holder’s receipt of a Change of Control Notice or the Holder becoming aware of a Change of Control if a Change of Control Notice is not delivered to the Holder in accordance with the immediately preceding


  
 16 













 
sentence (as applicable) and ending on twenty (20) Trading Days after the later of (A) the date of consummation of such Change of Control or (B) the date of receipt of such Change
of Control Notice or (C) the date of the announcement of such Change of Control, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control Redemption
Notice”) to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by
the Company in cash at a price equal to the greatest of (i) the product of (w) the Change of Control Redemption Premium multiplied by (y) the Conversion Amount being redeemed, (ii) solely if after the Public Company Date, the
product of (x) the Change of Control Redemption Premium multiplied by (y) the product of (A) the Conversion Amount being redeemed multiplied by (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 (1) the consummation of the applicable Change of Control and (2) 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 Conversion Price then in effect and (iii) the product of (y) the Change of Control Redemption Premium multiplied by (z) the product of
(A) the Conversion Amount being redeemed multiplied by (B) the quotient of (I) the aggregate cash consideration and the aggregate cash value of any non-cash consideration per share of Common
Stock to be paid to the holders of the shares of Common Stock upon consummation of such Change of Control (any such non-cash consideration constituting publicly-traded securities shall be valued at the highest
of the Closing Sale Price of such securities as of the Trading Day immediately prior to the consummation of such Change of Control, the Closing Sale Price of such securities on the Trading Day immediately following the public announcement of such
proposed Change of Control and the Closing Sale Price of such securities on the Trading Day immediately prior to the public announcement of such proposed Change of Control) divided by (II) the Conversion Price then in effect (the
“Change of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 11 and shall have priority to payments to stockholders in connection with such 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 this 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 Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption
under this Section 5(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. In the event of the Company’s redemption of any portion of this 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 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. RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS. 

(a) Purchase Rights. In addition to any adjustments pursuant to Section 7 below, if at any time the Company grants,
issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to all or substantially all of the record holders of any class of Common Stock (the “Purchase Rights”),
then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete
conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note and assuming for such purpose that the Note was converted at the Alternate Conversion Price as of the applicable record date)
immediately prior to the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant,
issue or sale of such Purchase Rights (provided, however, that, after the Public Company Date, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder and the other Attribution
Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares of Common Stock as a
result of such Purchase Right (and beneficial ownership) to the extent of any such excess) and such Purchase Right to such extent shall be held in abeyance (and, if such Purchase Right has an expiration date, maturity date or other similar
provision, such term shall be extended by such number of days held in abeyance, if applicable) for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties
exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right held similarly in abeyance (and, if
such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended by such number of days held in abeyance, if applicable)) to the same extent as if there had been no such limitation). 

(b) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the
consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the
Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option (i) in addition to the shares of Common Stock receivable upon such
conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without
taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares
of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially 

  
 18 













 
been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate.
Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Holder. The provisions of this Section 6 shall apply similarly and equally to successive Corporate Events and shall be applied without regard
to any limitations on the conversion or redemption of this Note. 
 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 and
on or prior to the second anniversary of the Issuance Date the Company grants, issues or sells (or enters into any agreement to grant, issue or sell), or in accordance with this Section 7(a) is deemed to have granted, 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 any Excluded Securities granted, issued or sold or deemed to have been granted, issued or sold) for a
consideration per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior to such granting, issuance or sale or deemed granting, issuance or sale (such Conversion Price then in
effect is referred to herein as the “Applicable Price”) (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 all purposes of the foregoing (including, without limitation, determining the adjusted Conversion Price and the New Issuance Price under this Section 7(a)), the following shall be applicable: 

(i) Issuance of Options. If the Company in any manner grants, issues or sells (or enters into any agreement to grant,
issue or sell) any Options and the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise
of any such Option or otherwise pursuant to the terms 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 granting, issuance
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 at any time issuable upon the exercise of any such Option or upon conversion,
exercise or exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) 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 granting, issuance 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 or otherwise pursuant to the terms thereof and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable (or may become issuable assuming all possible market conditions) upon
the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof, minus (2) the sum of all amounts paid or payable to
the holder of such Option 

  
 19 













 
(or any other Person) with respect to any one share of Common Stock upon the granting, issuance 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 or otherwise pursuant to the terms thereof plus the value of any other consideration (including, without limitation, consideration consisting of cash, debt forgiveness, assets or any
other property) received or receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such share of
Common Stock or of such Convertible Securities upon the exercise of such Options or otherwise pursuant to the terms thereof or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible
Securities. 
 (ii) Issuance of Convertible Securities. If the Company in any manner issues or sells (or enters into
any agreement to issue or sell) any Convertible Securities and the lowest price per share for which one share of Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms 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 (or the time of execution of such agreement to issue or sell, as
applicable) 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 at any time issuable upon the conversion, exercise or
exchange thereof or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common
Stock upon the issuance or sale (or pursuant to the agreement to issue or sell, as applicable) of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security or otherwise pursuant to the terms thereof and
(y) the lowest conversion price set forth in such Convertible Security for which one share of Common Stock is issuable (or may become issuable assuming all possible market conditions) upon conversion, exercise or exchange thereof or otherwise
pursuant to the terms thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) with respect to any one share of Common Stock upon the issuance or sale (or the agreement to issue
or sell, as applicable) of such Convertible Security plus the value of any other consideration received or receivable (including, without limitation, any consideration consisting of cash, debt forgiveness, assets or other property) by, or benefit
conferred on, the holder of such Convertible Security (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise
or exchange of such Convertible Securities or otherwise pursuant to the terms thereof, and if any such issuance 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), except as contemplated below, no further adjustment of the Conversion Price shall be made by reason of such issuance or sale. 

  
 20 













 (iii) Change in Option Price or Rate of Conversion. If the purchase
or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or
exercisable or exchangeable for shares of Common Stock increases or decreases at any time (other than proportional changes in conversion or exercise prices, as applicable, in connection with an event referred to in Section 7(b) below), 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)(i), if the terms of any Option or Convertible Security (including,
without limitation, 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. If
any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary Security”,
and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”), together comprising one integrated transaction (or one or more transactions if such issuances or sales or deemed issuances or sales of
securities of the Company either (A) have at least one investor or purchaser in common, (B) are consummated in reasonable proximity to each other and/or (C) are consummated under the same plan of financing), the aggregate
consideration per share of Common Stock with respect to such Primary Security shall be deemed to be equal to the difference of (x) the lowest price per share for which one share of Common Stock was issued (or was deemed to be issued pursuant to
Section 7(a)(i) or 7(a)(ii) above, as applicable) in such integrated transaction solely with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the sum of (I) the Black Scholes Consideration Value
of each such Option, if any, (II) the fair market value (as determined by the Holder in good faith) or the Black Scholes Consideration Value, as applicable, of such Adjustment Right, if any, and (III) the fair market value (as determined
by the Holder) of such Convertible Security, if any, in each case, as determined on a per share basis in accordance with this Section 7(a)(iv). 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 received therefor (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes
Consideration Value) will be deemed to be the net amount of consideration 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 (for the purpose 

  
 21 













 
of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) 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 for such securities will be the arithmetic average of the VWAPs of such security
for each of the five (5) Trading Days immediately preceding the date of receipt. 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 (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of
the calculation of the Black Scholes Consideration Value) 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 Holder. 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) Trading Days after the tenth (10th) day following such Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. 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 borne by the Company. 
 (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 issuance 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). 

(b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of
Section 6, Section 17 or Section 7(a), if the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) 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. Without limiting any provision of Section 6, Section 17 or
Section 7(a), if the Company at any time on or after the Subscription Date combines (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) 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. Any adjustment pursuant to this Section 7(b) shall become effective immediately after the effective
date of such subdivision or combination. If any event requiring an adjustment under this Section 7(b) occurs during the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted
appropriately to reflect such event. 

  
 22 













 (c) Holder’s Right of Adjusted Conversion Price. In addition to
and not in limitation of the other provisions of this Section 7, if the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options or Convertible Securities (any such securities,
“Variable Price Securities”), after the Subscription Date that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market
price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar
transactions) (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the Company shall provide written notice thereof via electronic mail and overnight courier to the Holder on the date
of such agreement and the issuance of such Common Stock, Convertible Securities or Options. From and after the date the Company enters into such agreement or issues any such Variable Price Securities, the Holder shall have the right, but not the
obligation, in its sole discretion to substitute the Variable Price for the Conversion Price upon conversion of this Note by designating in the Conversion Notice delivered upon any conversion of this Note that solely for purposes of such conversion
the Holder is relying on the Variable Price rather than the Conversion Price then in effect. The Holder’s election to rely on a Variable Price for a particular conversion of this Note shall not obligate the Holder to rely on a Variable Price
for any future conversion of this Note. 
 (d) Other Events. In the event that the Company (or any Subsidiary) shall
take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or 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 shall in good faith determine
and implement an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 7(d) will increase the Conversion Price as otherwise determined pursuant to
this Section 7, provided further that if the Holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Company’s board of directors and the Holder shall agree, in good
faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding absent manifest error and whose fees and expenses shall be borne by the Company. 

(e) Calculations. All calculations under this Section 7 shall be made by rounding to the nearest cent or the
nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the
disposition of any such shares shall be considered an issue or sale of Common Stock. 

  
 23 













 (f) 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 (as defined in the Securities Purchase Agreement), reduce the then current Conversion Price of each of the Notes to any amount and for any period of time deemed
appropriate by the board of directors of the Company; provided, that if after the Public Company Date, ay such reduction shall be subject to the rules and regulations of the Principal Market. 

(g) Adjustment Upon Public Company Date and Qualified Offering. 

(i) If a Public Company Date occurs without the occurrence of a Qualified Offering with respect thereto and, if on the Public
Company Date, the Closing Bid Price of the Common Stock on the Public Company Date is less than the Conversion Price then in effect (the “No QO Measuring Price”), immediately following the Public Company Date the Conversion Price
shall automatically lower to the No QO Measuring Price. 
 (ii) Upon the occurrence of a Qualified Offering, if 70% of the
New Issuance Price of such Qualified Offering is less than the Conversion Price then in effect (the “QO Measuring Price”), immediately following the time of consummation of such Qualified Offering (and prior to any Automatic
Conversion hereunder), the Conversion Price shall automatically lower to the QO Measuring Price. 
 8. REDEMPTIONS AT THE COMPANY’S
ELECTION. 
 (a) Company Optional Redemption. At any time after the first anniversary of the Subscription Date, so
long as no Equity Conditions Failure exists, the Company shall have the right to redeem all, but not less than all, of the Conversion Amount then remaining under this Note (the “Company Optional Redemption Amount”) on the Company
Optional Redemption Date (each as defined below) (a “Company Optional Redemption”). The portion of this Note subject to redemption pursuant to this Section 8(a) shall be redeemed by the Company in cash at a price (the
“Company Optional Redemption Price”) equal to 115% of the greater of (i) the Conversion Amount being redeemed as of the Company Optional Redemption Date and (ii) solely if after the Public Company Date, the product of
(1) the Conversion Rate with respect to the Conversion Amount being redeemed as of the Company Optional Redemption Date multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing
on the date immediately preceding such Company Optional Redemption Notice Date and ending on the Trading Day immediately prior to the date the Company makes the entire payment required to be made under this Section 8(a). The Company may
exercise its right to require redemption under this Section 8(a) by delivering a written notice thereof by electronic mail and overnight courier to all, but not less than all, of the holders of Notes (the “Company Optional Redemption
Notice” and the date all of the holders of Notes received such notice is referred to as the “Company Optional Redemption Notice Date”). The Company may deliver only one Company Optional Redemption Notice hereunder and such
Company Optional Redemption Notice shall be irrevocable. The Company Optional Redemption Notice shall (x) state the date on which 

  
 24 













 
the Company Optional Redemption shall occur (the “Company Optional Redemption Date”) which date shall not be less than twenty (20) calendar days nor more than ninety
(90) calendar days following the Company Optional Redemption Notice Date, (y) certify that there has been no Equity Conditions Failure and (z) state the aggregate Conversion Amount of the Notes which is being redeemed in such Company
Optional Redemption from the Holder and all of the other holders of the Notes pursuant to this Section 8 (and analogous provisions under the Other Notes) on the Company Optional Redemption Date. Notwithstanding anything herein to the contrary,
(i) if no Equity Conditions Failure has occurred as of the Company Optional Redemption Notice Date but an Equity Conditions Failure occurs at any time prior to the Company Optional Redemption Date, (A) the Company shall provide the Holder
a subsequent notice to that effect and (B) unless the Holder waives the Equity Conditions Failure, the Company Optional Redemption shall be cancelled and the applicable Company Optional Redemption Notice shall be null and void and (ii) at
any time prior to the date the Company Optional Redemption Price is paid, in full, the Company Optional Redemption Amount may be converted, in whole or in part, by the Holder into shares of Common Stock pursuant to Section 3. All Conversion
Amounts converted by the Holder after the Company Optional Redemption Notice Date shall reduce the Company Optional Redemption Amount of this Note required to be redeemed on the Company Optional Redemption Date. Redemptions made pursuant to this
Section 8 shall be made in accordance with Section 11. In the event of the Company’s redemption of any portion of this Note under this Section 8, 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 redemption premium due under this Section 8 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. For the avoidance of doubt, the Company shall have no right to effect a Company Optional Redemption if any
Event of Default has occurred and continuing, but any Event of Default shall have no effect upon the Holder’s right to convert this Note in its discretion. 

(b) Pro Rata Redemption Requirement. If the Company elects to cause a Company Optional Redemption of this Note pursuant
to Section 8, then it must simultaneously take the same action with respect to all of the Other Notes. 
 9. NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) 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. Without limiting the generality of the foregoing or any other provision of this
Note or the other Transaction Documents, the Company (a) shall not increase the par value of any shares of Common Stock receivable upon conversion of this Note above the Conversion Price then in effect, and (b) shall take all such actions
as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the conversion of this Note. Notwithstanding anything herein to the contrary, if after the


  
 25 













 
sixty (60) calendar day anniversary of the Issuance Date, the Holder is not permitted to convert this Note in full for any reason (other than pursuant to restrictions set forth in
Section 3(d) hereof), the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining such consents or approvals as necessary to permit such conversion into shares of Common Stock. 

10. RESERVATION OF AUTHORIZED SHARES. 

(a) Reservation. As of the Closing Date, the Company shall have reserved from its duly authorized capital stock not less
than 60,000,000 shares of Common Stock for issuance upon conversion of the Notes and exercise of the SPA Warrants. From and after January 31, 2022, so long as any of the Notes remain outstanding, the Company shall take all action necessary to
at all times have authorized, and reserved for the purpose of issuance, no less than 200% of the sum of (i) the maximum number of shares of Common Stock issuable upon conversion of all the Notes then outstanding (assuming for purposes hereof
that (x) the Notes are convertible at the Alternate Conversion Price then in effect assuming an Alternate Conversion Date as of the applicable date of determination, (y) interest on the Notes shall accrue through the third anniversary of
the Closing Date and will be converted in shares of Common Stock at a conversion price equal to the Alternate Conversion Price assuming an Alternate Conversion Date as of the applicable date of determination and (z) any such conversion shall
not take into account any limitations on the conversion of the Notes set forth in the Notes, and (ii) the maximum number of Warrant Shares issuable upon exercise of all the Warrants then outstanding (without regard to any limitations on the
exercise of the Warrants set forth therein) (collectively, the “Required Reserve Amount”); provided, that at no time shall the number of Shares of Common Stock reserved pursuant to this Section be reduced other than proportionally
in connection with any conversion, exercise and/or redemption, as applicable, of the Notes. The Required Reserve Amount (including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the holders
of the Notes based on the original principal amount of the Notes held by each holder on the Closing Date or increase in the number of reserved shares, as the case may be (the “Authorized Share Allocation”). In the event that a
holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which
ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders. 

(b) Insufficient Authorized Shares. If at any time after January 31, 2022, the number of shares of Common Stock
authorized and reserved for issuance is not sufficient to meet the Required Reserve Amount (an “Authorized Share Failure”), the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number
of shares, including, without limitation, calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations pursuant to the Transaction Documents, in the case of an insufficient number of authorized
shares, obtain stockholder approval of an increase in such authorized number of shares, and voting the management shares of the Company in favor of an increase in the authorized shares of the Company to ensure that the number of authorized shares is
sufficient to meet the Required 

  
 26 













 
Reserve Amount. On or prior to January 31, 2022 (the “Consent Deadline”), holders of a majority of the issued and outstanding shares of Common Stock and the Preferred Stock
shall have voted by written consent (the “Stockholder Resolutions”) approving an amendment to the Certificate of Incorporation to, among other items, approve a reverse stock split and, on an advisory basis, approve the transactions
contemplated by this Agreement (the “Stockholder Approval”, and the date the Stockholder Approval is obtained, the “Stockholder Approval Date”). Thereafter, the Company shall provide each stockholder entitled to
vote at a meeting of stockholders of the Company notice of the Consent Action (the “Consent Notice”). The Stockholder Resolutions and the Consent Notice shall be in a form reasonably acceptable to the Buyers and Kelley
Drye & Warren LLP, at the expense of the Company, with the Company obligated to reimburse the expenses of Kelley Drye & Warren LLP incurred in connection therewith in an amount not exceed $3,000, The Company shall be obligated to
seek to obtain the Stockholder Approval by the Consent Deadline. If, despite the Company’s reasonable best efforts the Stockholder Approval is not obtained on or prior to the Consent Deadline, the Company shall cause either an additional
consent action or a stockholder meeting to be held on or prior to March 31, 2021. If, despite the Company’s reasonable best efforts the Stockholder Approval is not obtained after such subsequent consent action or stockholder meeting,
the Company shall cause an additional consent action or stockholder meeting to be held semi-annually thereafter until such Stockholder Approval is obtained. 

11. REDEMPTIONS. 

(a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder in cash within
five (5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice. 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 in cash concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control and within five (5) Business
Days after the Company’s receipt of such notice otherwise. The Company shall deliver the applicable Company Optional Redemption Price to the Holder in cash on the applicable Company Optional Redemption Date. Notwithstanding anything herein to
the contrary, in connection with any redemption hereunder at a time the Holder is entitled to receive a cash payment under any of the other Transaction Documents, at the option of the Holder delivered in writing to the Company, the applicable
Redemption Price hereunder shall be increased by the amount of such cash payment owed to the Holder under such other Transaction Document and, upon payment in full or conversion in accordance herewith, shall satisfy the Company’s payment
obligation under such other Transaction Document. In the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with
Section 20(d)) representing the outstanding Principal which has not been redeemed. 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 

  
 27 













 
which the applicable Redemption Price (together with any Late Charges thereon) 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 20(d)), to the Holder, and in each case the principal amount of this Note or
such new Note (as the case may be) shall be increased by an amount equal to the difference between (1) the applicable Redemption Price (as the case may be, and as adjusted pursuant to this Section 11, if applicable) minus (2) the
Principal portion of the Conversion Amount submitted for redemption and (z) the Conversion Price of this Note or such new Notes (as the case may be) shall be automatically adjusted with respect to each conversion effected thereafter by the
Holder to the lowest of (A) the Conversion Price as in effect on the date on which the applicable Redemption Notice is voided, (B) 75% of 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 and (C) 75% of the quotient of (I) the sum of the five (5) lowest VWAPs of the
Common Stock during the twenty (20) consecutive Trading Day period ending and including the applicable Conversion Date divided by (II) five (5) (it being understood and agreed that all such determinations shall be appropriately adjusted
for any stock dividend, stock split, stock combination or other similar transaction during such period). The Holder’s delivery of a notice voiding a Redemption Notice and exercise of its rights following such notice shall not affect the
Company’s obligations to make any payments of Late Charges which have accrued prior to the date of such notice with respect to the Conversion Amount subject to such notice. 

(b) Redemption by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes
for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(b) or Section 5(b) (each, an “Other Redemption Notice”), the Company shall
immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile or electronic mail a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices,
during the seven (7) Business Day period beginning on and including the date which is two (2) Business Days prior to the Company’s receipt of the Holder’s applicable Redemption Notice and ending on and including the date which is
two (2) Business Days after the Company’s receipt of the Holder’s applicable Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other
Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption
pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven (7) Business Day period. 

12. VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law (including, without
limitation, the Texas Business Organizations Code) and as expressly provided in this Note. 
 13. NEGATIVE COVENANTS.

otherwise satisfied in accordance with their terms, the Company shall not, and the Company shall not permit any of its Subsidiaries without the prior written consent of the Required Holders to, directly or indirectly:

payment in respect of principal of (or premium, if any) or interest on, such Indebtedness if at the time such payment with respect to such Indebtedness is due or is otherwise made or, after giving effect to such payment, (i) an event
constituting an Event of Default has occurred and is continuing or (ii) an event that with the passage of time and without being cured would constitute an Event of Default has occurred and is continuing;

course of business in a manner and to an extent consistent with past practice and necessary or desirable for the prudent operation of its business, for fair consideration and on terms no less favorable to it or its Subsidiaries than would be

 (xi) prior to the
Public Company Date, amend, repeal, restate, supplement or otherwise modify its or any Subsidiary’s Organizational Documents in a manner adverse to the holders of Notes;

contemplated to be conducted by the Company and each of its Subsidiaries on the Subscription Date or any business substantially related or incidental thereto. The Company shall not, and the Company shall cause each of its Subsidiaries to not,
directly or indirectly, modify its or their corporate structure or purpose;

cause a breach or default under the Notes or the Warrants; 
 (xiv) issue any debt (other than the Notes and the Other Notes)

14. AFFIRMATIVE COVENANTS. Until all of the Notes have been converted, exchanged, redeemed or otherwise satisfied in accordance with

 31 













 15. Additional Covenants. 

(a) Stay, Extension and Usury Laws. To the extent that it may lawfully do so, the Company (A) agrees that it will
not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law (wherever or whenever enacted or in force) that may affect the covenants or the performance of this Note; and
(B) expressly waives all benefits or advantages of any such law and agrees that it will not, by resort to any such law, hinder, delay or impede the execution of any power granted to the Holder by this Note, but will suffer and permit the
execution of every such power as though no such law has been enacted. 
 (b) Taxes. The Company and its Subsidiaries
shall pay when due all material taxes, fees or other charges of any nature whatsoever (together with any related interest or penalties) now or hereafter imposed or assessed against the Company and its Subsidiaries or their respective assets or upon
their ownership, possession, use, operation or disposition thereof or upon their rents, receipts or earnings arising therefrom (except where the failure to pay would not, individually or in the aggregate, have a material effect on the Company or any
of its Subsidiaries). The Company and its Subsidiaries shall file on or before the due date therefor all personal property tax returns (except where the failure to file would not, individually or in the aggregate, have a material effect on the
Company or any of its Subsidiaries). Notwithstanding the foregoing, the Company and its Subsidiaries may contest, in good faith and by appropriate proceedings, taxes for which they maintain adequate reserves therefor in accordance with GAAP. 

(c) Independent Investigation. At the request of the Holder (subject to the last sentence of this
Section 15(c)) either (x) at any time when an Event of Default has occurred and is continuing, (y) upon the occurrence of an event that with the passage of time or giving of notice would constitute an Event of
Default or (z) at any time the Holder reasonably believes an Event of Default may have occurred or be continuing, the Company shall hire an independent, reputable investment bank selected by the Company and approved by the Holder to investigate
as to whether any breach of this Note has occurred (the “Independent Investigator”). If the Independent Investigator determines that such breach of this Note has occurred, the Independent Investigator shall notify the Company of
such breach and the Company shall deliver written notice to each holder of a Note of such breach. In connection with such investigation, the Independent Investigator may, during normal business hours, inspect all contracts, books, records,
personnel, offices and other facilities and properties of the Company and its Subsidiaries and, to the extent available to the Company after the Company uses reasonable efforts to obtain them, the records of its legal advisors and accountants
(including the accountants’ work papers) and any books of account, records, reports and other papers not contractually required of the Company to be confidential or secret, or subject to attorney-client or other evidentiary privilege, and the
Independent Investigator may make such copies and inspections thereof as the Independent Investigator may reasonably request. The Company shall furnish the Independent Investigator with such financial and operating data and other information with
respect to the business and properties of the Company as the Independent Investigator may reasonably request. The Company shall permit the Independent Investigator to discuss the affairs, finances and accounts of the Company with, and to make
proposals and furnish advice with respect thereto to, the Company’s officers, directors, key employees and independent public accountants or any of them (and by this provision the Company authorizes said accountants to discuss with such
Independent Investigator the finances and affairs of the Company and any Subsidiaries), all at such reasonable times, upon reasonable notice, and as often as may be reasonably requested. Notwithstanding the foregoing, the Holder shall only have
rights under this Section 15(c) if the Original Principal Amount of this Note, plus the Original Principal Amount of any Other Notes held by the Holder or its Affiliates, is greater than or equal to $500,000 in the
aggregate. 

  
 32 













 16. SECURITY; SUBORDINATION. This Note and the Other Notes are secured to the extent
and in the manner set forth in the Transaction Documents (including, without limitation, the Security Agreement, the other Security Documents), except the Liens created for the benefit of the holders of Notes with respect to the Security Documents

 21. REMEDIES, CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF.
The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive
relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note. No failure on the part of the Holder to exercise, and no delay in
exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Holder of any right, power or remedy preclude any other or further exercise thereof or the exercise of any other
right, power or remedy. In addition, the exercise of any right or remedy of the Holder at law or equity or under this Note or any of the documents shall not be deemed to be an election of Holder’s rights or remedies under such documents or at
law or equity. The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like
(and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder
shall be entitled, in addition to all other available remedies, to specific performance and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of competent jurisdiction in any such case without the necessity
of proving actual damages and without posting a bond or other security. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the
terms and conditions of this Note (including, without limitation, compliance with Section 7).

Company shall pay the costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, attorneys’ fees and
disbursements. The Company expressly acknowledges and agrees that no amounts due under this Note shall be affected, or limited, by the fact that the purchase price paid for this Note was less than the original Principal amount hereof. 

23. CONSTRUCTION; HEADINGS. This Note shall be deemed to be jointly drafted by the Company and the initial Holder and shall not be
construed against any such Person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation of, this Note. Unless the context clearly indicates otherwise, each pronoun
herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed by
the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Note instead of just the provision in which they are found. Unless expressly indicated
otherwise, all section references are to sections of this Note. Terms used in this Note and not otherwise defined herein, but defined in the other Transaction Documents, shall have the meanings ascribed to such terms on the Closing Date in such
other Transaction Documents unless otherwise consented to in writing by the Holder. 

  
 35 













 24. FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the part of the Holder
in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or
privilege. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party. Notwithstanding the foregoing, nothing contained in this Section 24 shall permit any waiver of any provision of
Section 3(d).

submits to the exclusive jurisdiction of the state and federal courts sitting in The City of Chicago, County of Cook, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient

deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect 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).
