SECOND AMENDMENT 
 TO THE
PEOPLE’S UNITED BANK, N.A. 
 401(k) EMPLOYEE SAVINGS PLAN 

SIXTH AMENDMENT AND RESTATEMENT 

WHEREAS, People’s United Bank, National Association, a national banking association organized under the laws of the United States
(the “Bank”), maintains the People’s United Bank, N.A. 401(k) Employee Savings Plan (the “Plan”) for the benefit of certain of its employees who meet certain qualifications and for the qualifying employees of its affiliates
that have adopted the Plan; and 
 WHEREAS, the Plan has always constituted and has always been intended to constitute a tax-
qualified Plan meeting the requirements of Section 401(a) of the Internal Revenue Code, as amended from time to time (the “Code”) and all other requirements applicable to the Plan under ERISA; and 

WHEREAS, the Plan has been amended from time to time, and restated most recently in the form of the Sixth Amendment and Restatement as
of January 1, 2020; and 
 WHEREAS, the Bank has reserved the right to make amendments from time to time to the Plan as restated,
pursuant to Sections 10.1 and 10.2 thereof; and 
 WHEREAS, upon recommendation of the HR Administrative Committee, the Enterprise
Risk Committee has determined to (i) eliminate one investment option from the Plan and (ii) add one new investment option to the Plan, and pursuant to Section 10.2(a) of the Plan has determined to amend the Plan to reflect such
changes; and 
 WHEREAS, the undersigned officer has been duly authorized to execute such amendments. 

NOW, THEREFORE, the Bank hereby amends the Plan as follows, effective February 25, 2022: 

1. Addendum I is amended in its entirety to read as set forth in Addendum I attached hereto. 

2. The amendments made hereby shall become effective as set forth herein, subject to the provisions of this paragraph. If applicable Internal Revenue Service
(“IRS”) procedures so permit, the Plan as amended may be submitted to the Internal Revenue Service (the “IRS”) with a request for a written ruling to the effect that the provisions as set forth herein will result in the Plan
continuing to be a qualified Plan as set forth in the provisions of Section 401 of the Internal Revenue Code of 1986, as it may from time to time be amended. To the extent that any provisions contained in such amendments would contain any
provision which would adversely affect such qualified status in the opinion of the IRS, such provisions, subject to the last sentence of this paragraph, shall become null and void. Further, the Plan shall be subject as of the applicable effective
date set forth herein to all provisions of any further amendments so made in response to any suggestions, comments or requests by any personnel of the IRS in connection with the request described in this paragraph. Notwithstanding the foregoing, in
the event that any action for declaratory judgment is instituted in the Tax Court in connection with any refusal or failure to issue such written determination by the IRS or any adverse action with respect to such request, the putting into effect of
any such amendment shall be further postponed, but all amendments shall be made in accordance with the decision of the Tax Court or such decision as it may be altered or changed upon further proceedings before the Tax Court or any appeal therefrom,
all as of the applicable effective date indicated herein. 

 IN WITNESS WHEREOF, People’s United Bank, N. A., acting by its duly authorized
officer, hereby executes this amendment to be effective as herein provided.

redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on the
Outstanding Principal Value of this Note 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, on any Installment
Date with respect to the Installment Amount due on such Installment Date, or upon acceleration, conversion, redemption or otherwise (in
each case in accordance with the terms hereof). This Senior Secured Convertible Note (including all Senior Secured Convertible Notes
issued in exchange, transfer or replacement hereof, this “Note”) is one of an issue of Senior Secured Convertible
Notes (collectively, the “Notes”, and such other Senior Secured Convertible Notes, the “Other Notes”)
issued pursuant to (i) Section 1 of that certain Securities Purchase Agreement, dated as of March 31, 2022 (the “Subscription
Date”), by and among the Company and the investors (the “Buyers”) referred to therein, as amended from time
to time (the “Securities Purchase Agreement”), and (ii) the Company’s Registration Statement on Form S-3 (File
number 333-261814) (the “Registration Statement”). Certain capitalized terms used herein are defined in Section 33.

 

    	 

     

    

 

1.
PAYMENTS OF PRINCIPAL. On each Installment Date, the Company shall pay to the Holder an amount equal to the Installment Amount
due on such Installment Date in accordance with Section 8. On the Maturity Date, the Company shall pay to the Holder an amount in cash
(excluding any amounts paid in shares of Common Stock on the Maturity Date in accordance with Section 8) representing the Outstanding
Value of this Note as of the Maturity Date. Other than as specifically permitted by this Note, the Company may not prepay any portion
of the Outstanding Principal Value, accrued and unpaid Interest or accrued and unpaid Late Charges on the Outstanding Principal Value
and Interest, if any. Notwithstanding anything herein to the contrary, with respect to any conversion or redemption hereunder, as applicable,
the Company shall convert or redeem, as applicable, First, all accrued and unpaid Late Charges on any Outstanding Principal Value
and Interest hereunder and under any other Notes held by the Holder and all other amounts owed to the Holder under any other Transaction
Document, Second, all accrued and unpaid Interest hereunder and under any other Notes held by such Holder, Third, all other
amounts (other than the Outstanding Principal Value) outstanding under any other Notes held by such Holder and, Fourth, the Outstanding
Principal Value hereunder and under any other Notes held by such Holder, in each case, allocated pro rata among this Note and such other
Notes held by such Holder.

 

2.
INTEREST; INTEREST RATE.

 

(a)
Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the Outstanding Principal Value of this Note
and on basis of a 360-day year and twelve 30-day months and shall be payable in arrears on each Interest Date and shall compound each
calendar month and shall be payable in accordance with the terms of this Note. Interest shall be paid (i) on each Interest Date occurring
on an Installment Date in accordance with Section 8 as part of the applicable Installment Amount due on the applicable Installment Date
and (ii) with respect to each other Interest Date, on such Interest Date in cash.

 

(b)
Prior to the payment of Interest on an Interest 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 13 or any required payment upon any Bankruptcy Event of Default. From and after the occurrence and during
the continuance of any Event of Default (regardless of whether the Company has delivered an Event of Default Notice to the Holder or
if the Holder has delivered an Event of Default Redemption Notice to the Company or otherwise notified the Company that an Event of Default
has occurred), the Interest Rate shall automatically be increased to eighteen percent (18.0%) 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 applicable Interest 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 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 (A) the portion of the Outstanding Principal Value of this Note to be converted,
redeemed or otherwise with respect to which this determination is being made, (B) accrued and unpaid Interest with respect to such Outstanding
Principal Value of this Note, (C) accrued and unpaid Late Charges with respect to such Outstanding Principal Value of this Note and Interest,
and (D) any other unpaid amounts pursuant to the Transaction Documents, if any.

 

(ii)
“Conversion Price” means, as of any Conversion Date or other date of determination, $5.00, subject to adjustment as
provided herein.

 

    	3

     

    

 

(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 6:00 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 (it being agreed that the date of receipt shall be determined in accordance
with Section 9(f) of the Securities Purchase Agreement), 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 the Company’s transfer agent (the “Transfer Agent”) which confirmation shall constitute an
instruction 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) provided 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 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 Value of this Note is greater
than the Outstanding Principal Value 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 Value of this Note 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. In the event of a partial conversion
of this Note pursuant hereto, the Outstanding Principal Value of this Note converted shall be deducted from the Installment Amount(s)
relating to the Installment Date(s) as set forth in the applicable Conversion Notice.

 

    	4

     

    

 

(ii)
Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, on or prior to the applicable
Share Delivery Deadline, 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) (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 one percent (1%) 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 prior to the Share Delivery Deadline 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, and if on or after such Share Delivery Deadline
the Holder acquires (in an open market transaction, 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, 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 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.

 

    	5

     

    

 

(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 Outstanding Principal Value 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 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 Outstanding Principal Value, 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 Outstanding Principal Value, 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.

 

    	6

     

    

 

(d)
Limitations on Conversions.

 

(i)
Beneficial Ownership. 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, without limitation, any convertible notes or convertible preferred stock or 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)(i).
For purposes of this Section 3(d)(i), 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”).
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)(i), 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. 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 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)(i) 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)(i)
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.

(ii)
Principal Market Regulation The Company shall not issue any shares of Common Stock upon conversion of this Note or otherwise pursuant
to the terms of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock
which the Company may issue upon conversion of the Notes or otherwise pursuant to the terms of this Note without breaching the Company’s
obligations under the rules or regulations of the Principal Market (the number of shares which may be issued without violating such rules
and regulations, including rules related to the aggregate of offerings under NASDAQ Listing Rule 5635(d), the “Exchange Cap”),
except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by
the applicable rules of the Principal Market for issuances of shares of Common Stock upon conversion of the Notes or otherwise pursuant
to the terms of this Note in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval
is not required, which opinion shall be reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained,
no Buyer shall be issued in the aggregate, upon conversion of any Notes or otherwise pursuant to the terms of this Note, shares of Common
Stock in an amount greater than the product of (i) the Exchange Cap multiplied by (ii) the quotient of (A) the aggregate original principal
amount of Notes issued to such Buyer pursuant to the Securities Purchase Agreement on the Initial Closing Date (as defined in the Securities
Purchase Agreement) divided by (B) the aggregate original principal amount of all Notes issued to the Buyers pursuant to the Securities
Purchase Agreement on the Initial Closing Date (with respect to each Buyer, the “Exchange Cap Allocation”). In the
event that any Buyer shall sell or otherwise transfer any of such Buyer’s Notes, the transferee shall be allocated a pro rata portion
of such Buyer’s Exchange Cap Allocation with respect to such portion of such Notes so transferred, and the restrictions of the
prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such transferee.
Upon conversion in full of a holder’s Notes, the difference (if any) between such holder’s Exchange Cap Allocation and the
number of shares of Common Stock actually issued to such holder upon such holder’s conversion in full of such holder’s Notes
shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to
the shares of Common Stock underlying the Notes then held by each such holder. At any time after the date hereof, in the event that the
Company is prohibited from issuing shares of Common Stock pursuant to this Section 3(d)(ii) (the “Exchange Cap Shares”),
the Company shall pay cash in exchange for the cancellation of such shares of Common Stock at a price equal to the sum of (i) the product
of (x) such number of Exchange Cap Shares and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period
commencing on the date the Holder delivers the applicable Conversion Notice with respect to such Exchange Cap Shares to the Company and
ending on the date of such issuance and payment under this Section 3(d)(ii) and (ii) to the extent of any Buy-In related thereto, any
Buy-In Payment Amount, any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith
(collectively, the “Exchange Cap Share Cancellation Amount”).

 

(e)
Right of Alternate Conversion Upon an Event of Default.

 

(i)
General. Subject to Section 3(d), at any time during an Event of Default Redemption Right Period (as defined below) with respect
to an Alternate Conversion Event of Default (regardless of whether such Event of Default has been cured, or if the Company has delivered
an Event of Default Notice to the Holder or if the Holder has delivered an Event of Default Redemption Notice to the Company or otherwise
notified the Company that an Event of Default has occurred), 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, each, an “Alternate
Conversion Amount”) into shares of Common Stock at the Alternate Conversion Price.

 

    	8

     

    

 

(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; provided that in the event of the Conversion Floor Price Condition, on the applicable Alternate Conversion Date
the Company shall also deliver to the Holder the applicable Alternate Conversion Floor Amount. 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).

pending appeal, or are not discharged within 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 $150,000 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;

 

(xii)
the Company and/or any Subsidiary, individually or in the aggregate, either (i) fails to pay, when due, or within any applicable grace
period, any payment with respect to any Indebtedness in excess of $150,000 due to any third party (other than, with respect to unsecured
Indebtedness only, payments contested by the Company and/or such Subsidiary (as the case may be) in good faith by proper proceedings
and with respect to which adequate reserves have been set aside for the payment thereof in accordance with GAAP) or is otherwise in breach
or violation of any agreement for monies owed or owing in an amount in excess of $150,000, which failure to pay, breach or violation
permits the other party thereto to declare an event of default or otherwise accelerate amounts due thereunder, or (ii) suffer to exist
any other circumstance or event that would, with or without the passage of time or the giving of notice, result in a default or event
of default under any agreement binding the Company or any Subsidiary, which default or event of default would or is likely to have a
material adverse effect on the business, 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;

 

    	11

or warranty, in any material respect (other than representations or warranties subject to material adverse effect or materiality, 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

(xvi)
any Material Adverse Effect (as defined in the Securities Purchase Agreement) occurs (other than any material adverse development or
material adverse change with respect to any products of the Company);

 

(xvii)

Document (including, without limitation, the Security Documents);

 

    	12

     

    

 

(xviii)
any Security Document shall for any reason fail or cease to create a separate valid and perfected and, except to the extent permitted
by the terms hereof or thereof, first priority Lien (as defined in the Securities Purchase Agreement) on the Collateral (as defined in
the Security Documents) in favor of the Collateral Agent (as defined in the Securities Purchase Agreement) 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

or substantial curtailment of revenue producing activities at any facility of the Company or any Subsidiary, if any such event or circumstance
has had, or is reasonably likely to have a Material Adverse Effect;

 

(xx)

    	13

     

    

 

(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 the occurrence 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 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) 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 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 13. 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 4(b), 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 a partial redemption of this Note pursuant hereto, the Outstanding Principal Value of this Note redeemed shall be deducted
from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in the Event of Default Redemption Notice.
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) the Outstanding Value of this Note, 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.

 

    	14

     

    

 

5.
RIGHTS UPON FUNDAMENTAL TRANSACTION.

 

(a)
Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless (i) 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 and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted
on or listed for trading on an Eligible Market. 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 publicly traded 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 Required Holders may elect, at their 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.

 

    	15

     

    

 

(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 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 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) 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 13 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 9. In the event of a partial redemption of this Note pursuant hereto,
the Outstanding Principal Value of this Note redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment
Date(s) as set forth in the Change of Control Redemption Notice. 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 Sections 7 and 17 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 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 up to ninety (90) Trading Days (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 the applicable expiration date, maturity date or similar time (as extended
pursuant to the foregoing), until such time or times during such extended period, if any, 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). The Holder shall be
deemed to have waived the right to receive any such Purchase Rights that remain held in abeyance at the end of such abeyance period if
not granted prior to such time.

 

(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 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.

RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

 

(a)
Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of Section 6 and
Section 17, 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 and Section 17, 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(a) shall become effective immediately after the effective date of such subdivision or combination.
If any event requiring an adjustment under this Section 7(a) 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.

 

(b)
Holder’s Right of Adjusted Conversion Price. In addition to and not in limitation of the other provisions of this Section
7 or in the Securities Purchase Agreement, 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”) regardless
of whether securities have been sold pursuant to such agreement and whether such agreement has subsequently been terminated, 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, as calculated pursuant to the agreements governing such Variable Price Securities, 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. In addition, from and after the date the Company enters into such agreement
or issues any such Variable Price Securities, for purposes of calculating the Installment Conversion Price as of any time of determination,
the “Conversion Price” as used therein shall mean the lower of (x) the Conversion Price as of such time of determination
and (y) the Variable Price as of such time of determination.

 

    	18

     

    

 

(c)
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.

 

(d)
Voluntary Adjustment by Company. Subject to the rules and regulations of the Principal Market, 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.

 

8.
INSTALLMENT CONVERSION OR REDEMPTION.

 

(a)
General. On each applicable Installment Date, provided there has been no Equity Conditions Failure, the Company shall pay to the
Holder of this Note the applicable Installment Amount due on such date by converting such Installment Amount in accordance with this
Section 8 (a “Installment Conversion”); provided, however, that the Company may, at its option following
notice to the Holder as set forth below, pay the Installment Amount by redeeming such Installment Amount in cash (a “Installment
Redemption”) or by any combination of an Installment Conversion and an Installment Redemption so long as all of the outstanding
applicable Installment Amount due on any Installment Date shall be converted and/or redeemed by the Company on the applicable Installment
Date, subject to the provisions of this Section 8. On a date which is on or prior to the eleventh (11th) Trading Day (but no earlier
than the sixteenth (16th) Trading Day) prior to each Installment Date (each such eleventh (11th) Trading Day, an
“Installment Notice Due Date”), the Company shall deliver written notice (each, a “Installment Notice”
and the date all of the holders receive such notice is referred to as to the “Installment Notice Date”), to each holder
of Notes and such Installment Notice shall (i) either (A) confirm that the applicable Installment Amount of such holder’s Note
shall be converted in whole pursuant to an Installment Conversion or (B) (1) state that the Company elects to redeem for cash, or is
required to redeem for cash in accordance with the provisions of the Notes, in whole or in part, the applicable Installment Amount pursuant
to an Installment Redemption and (2) specify the portion of such Installment Amount which the Company elects or is required to redeem
pursuant to an Installment Redemption (such amount to be redeemed in cash, the “Installment Redemption Amount”) and
the portion of the applicable Installment Amount, if any, with respect to which the Company will, and is permitted to, effect an Installment
Conversion (such amount of the applicable Installment Amount so specified to be so converted pursuant to this Section 8 is referred to
herein as the “Installment Conversion Amount”), which amounts when added together, must at least equal the entire
applicable Installment Amount and (ii) if the applicable Installment Amount is to be paid, in whole or in part, pursuant to an Installment
Conversion, certify that there is not then an Equity Conditions Failure as of the applicable Installment Notice Date. Each Installment
Notice shall be irrevocable. If the Company does not timely deliver an Installment Notice in accordance with this Section 8 with respect
to a particular Installment Date, then the Company shall be deemed to have delivered an irrevocable Installment Notice confirming an
Installment Conversion of the entire Installment Amount payable on such Installment Date and shall be deemed to have certified that there
is not then an Equity Conditions Failure in connection with such Installment Conversion. Except as expressly provided in this Section
8(a), the Company shall convert and/or redeem the applicable Installment Amount of this Note pursuant to this Section 8 and the corresponding
Installment Amounts of the Other Notes pursuant to the corresponding provisions of the Other Notes in the same ratio of the applicable
Installment Amount being converted and/or redeemed hereunder. The applicable Installment Conversion Amount (whether set forth in the
applicable Installment Notice or by operation of this Section 8) shall be converted in accordance with Section 8(b) and the applicable
Installment Redemption Amount shall be redeemed in accordance with Section 8(c).

 

    	19

     

    

 

(b)
Mechanics of Installment Conversion. Subject to Section 3(d), if the Company delivers an Installment Notice or is deemed to have
delivered an Installment Notice certifying that such Installment Amount is being paid, in whole or in part, in an Installment Conversion
in accordance with Section 8(a), then the remainder of this Section 8(b) shall apply. The applicable Installment Conversion Amount, if
any, shall be converted on the applicable Installment Date at the applicable Installment Conversion Price and the Company shall, on such
Installment Date, (A) deliver to the Holder’s account with DTC such shares of Common Stock issued upon such conversion (subject
to the reduction contemplated by the immediately following sentence and, if applicable, the penultimate sentence of this Section 8(b)),
and (B) in the event of the Conversion Floor Price Condition, the Company shall deliver to the Holder the applicable Conversion Installment
Floor Amount; provided that the Equity Conditions are then satisfied (or waived in writing by the Holder) on such Installment Date and
an Installment Conversion is not otherwise prohibited under any other provision of this Note. If the Company confirmed (or is deemed
to have confirmed by operation of Section 8(a)) the conversion of the applicable Installment Conversion Amount, in whole or in part,
and there was no Equity Conditions Failure as of the applicable Installment Notice Date (or is deemed to have certified that the Equity
Conditions in connection with any such conversion have been satisfied by operation of Section 8(a)) but an Equity Conditions Failure
occurred between the applicable Installment Notice Date and any time through the applicable Installment Date (the “Interim Installment
Period”), the Company shall provide the Holder a subsequent notice to that effect. If there is an Equity Conditions Failure
(which is not waived in writing by the Holder) during such Interim Installment Period or an Installment Conversion is not otherwise permitted
under any other provision of this Note, then, at the option of the Holder designated in writing to the Company, the Holder may require
the Company to do any one or more of the following: (i) the Company shall redeem all or any part designated by the Holder of the unconverted
Installment Conversion Amount (such designated amount is referred to as the “Designated Redemption Amount”) and the
Company shall pay to the Holder within two (2) days of such Installment Date, by wire transfer of immediately available funds, an amount
in cash equal to 132.5% of such Designated Redemption Amount, and/or (ii) the Installment Conversion shall be null and void with respect
to all or any part designated by the Holder of the unconverted Installment Conversion Amount and the Holder shall be entitled to all
the rights of a holder of this Note with respect to such designated part of the Installment Conversion Amount; provided, however, the
Conversion Price for such designated part of such unconverted Installment Conversion Amount shall thereafter be adjusted to equal the
lesser of (A) the Installment Conversion Price as in effect on the date on which the Holder voided the Installment Conversion and (B)
the Installment Conversion Price that would be in effect on the date on which the Holder delivers a Conversion Notice relating thereto
as if such date was an Installment Date. If the Company fails to redeem any Designated Redemption Amount by the second (2nd) day following
the applicable Installment Date by payment of such amount by such date, then the Holder shall have the rights set forth in Section 13
as if the Company failed to pay the applicable Installment Redemption Price (as defined below) and all other rights under this Note (including,
without limitation, such failure constituting an Event of Default described in Section 4(a)(v)). Notwithstanding anything to the contrary
in this Section 8(b), but subject to 3(d), until the Company delivers Common Stock representing the Installment Conversion Amount to
the Holder, the Installment Conversion Amount may be converted by the Holder into Common Stock pursuant to Section 3. In the event that
the Holder elects to convert the Installment Conversion Amount prior to the applicable Installment Date as set forth in the immediately
preceding sentence, the Installment Conversion Amount so converted shall be deducted from the Installment Amount(s) relating to the applicable
Installment Date(s) as set forth in the applicable Conversion Notice. The Company shall pay any and all taxes that may be payable with
respect to the issuance and delivery of any shares of Common Stock in any Installment Conversion hereunder.

 

    	20

     

    

 

(c)
Mechanics of Installment Redemption. If the Company elects or is required to effect an Installment Redemption, in whole or in
part, in accordance with Section 8(a), then the Installment Redemption Amount, if any, shall be redeemed by the Company in cash on the
applicable Installment Date by wire transfer to the Holder of immediately available funds in an amount equal to 115% of the applicable
Installment Redemption Amount (the “Installment Redemption Price”). If the Company fails to redeem such Installment
Redemption Amount on such Installment Date by payment of the Installment Redemption Price, then, at the option of the Holder designated
in writing to the Company (any such designation shall be a “Conversion Notice” for purposes of this Note), the Holder
may require the Company to convert all or any part of the Installment Redemption Amount at the Installment Conversion Price (determined
as of the date of such designation as if such date were an Installment Date). Conversions required by this Section 8(c) shall be made
in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(c), but subject to Section
3(d), until the Installment Redemption Price (together with any Late Charges thereon) is paid in full, the Installment Redemption Amount
(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 the Holder elects to convert all or any portion of the Installment Redemption Amount prior to the applicable Installment
Date as set forth in the immediately preceding sentence, the Installment Redemption Amount so converted shall be deducted from the Installment
Amounts relating to the applicable Installment Date(s) as set forth in the applicable Conversion Notice. Redemptions required by this
Section 8(c) shall be made in accordance with the provisions of Section 13.

 

(d)
Deferred Installment Amount. Notwithstanding any provision of this Section 8(d) to the contrary, the Holder may, at its option
and in its sole discretion, deliver a written notice to the Company no later than the Trading Day immediately prior to the applicable
Installment Date electing to have the payment of all or any portion of an Installment Amount payable on such Installment Date deferred
(such amount deferred, the “Deferral Amount”, and such deferral, each a “Deferral”) until any subsequent
Installment Date selected by the Holder, in its sole discretion, in which case, the Deferral Amount shall be added to, and become part
of, such subsequent Installment Amount and such Deferral Amount shall continue to accrue Interest hereunder. Any notice delivered by
the Holder pursuant to this Section 8(d) shall set forth (i) the Deferral Amount and (ii) the date that such Deferral Amount shall now
be payable.

 

(e)
Acceleration of Installment Amounts. Notwithstanding any provision of this Section 8 to the contrary, but subject to Section 3(d),
during the period commencing on an Installment Date (a “Current Installment Date”) and ending on the Trading Day immediately
prior to the next Installment Date (each, an “Installment Period”), at the option of the Holder, at one or more times,
the Holder may convert other Installment Amounts (each, an “Acceleration”, and each such amount, an “Acceleration
Amount”, and the Conversion Date of any such Acceleration, each an “Acceleration Date”), in whole or in
part, at the Acceleration Conversion Price of such Acceleration Date in accordance with the conversion procedures set forth in Section
3 hereunder (with “Acceleration Conversion Price” replacing “Conversion Price” for all purposes therein), mutatis
mutandis; provided, that if a Conversion Floor Price Condition exists with respect to such Acceleration Date, with each Acceleration
the Company shall also deliver to the Holder the Acceleration Floor Amount on the applicable Share Delivery Deadline.

 

(f)
Reallocation of Installment Amounts. Notwithstanding any provision of this Section 8 to the contrary, but subject to Section 3(d),
at any time with respect to the applicable Installment Amount subject to an Installment Conversion with respect to any given Current
Installment Date, the Holder may, at such Holder’s sole option, exercised by delivery of written notice to the Company (each, a
“Reallocation Notice”) reallocate (each, a “Reallocation”) all, or any part, of the Installment
Amount with respect to such Current Installment Date to a later date during the applicable Installment Period (each, a “Reallocation
Date”, and such portion of the applicable Installment Amount reallocated to a given Reallocation Date, each a “Reallocation
Amount”); provided, that the sum of the remaining Installment Amount not subject to Reallocation and each Reallocation Amount
with respect to each Reallocation Date in such applicable Installment Period shall not exceed the Installment Amount with respect to
such Current Installment Date prior to such Reallocation. On each Reallocation Date, the Reallocation Amount with respect to such Reallocation
Date shall automatically convert into shares of Common Stock at a conversion price equal to the applicable Reallocation Conversion Price
as if the Holder delivered a Conversion Notice on the second (2nd) Trading Day immediately prior to such Reallocation Date
(with “Reallocation Conversion Price” replacing “Conversion Price” for all purposes therein) in accordance with
the conversion procedures set forth in Section 3 hereunder, mutatis mutandis; provided, that if a Conversion Floor Price Condition
exists with respect to such Reallocation Date, the Company shall also deliver to the Holder the Reallocation Floor Amount on the applicable
Share Delivery Deadline with respect thereto.

9.
SUBSEQUENT PLACEMENT OPTIONAL REDEMPTION

 

(a)
General. At any time from and after the earlier of (x) the date the Holder becomes aware of the occurrence of a Subsequent Placement
(as defined in the Securities Purchase Agreement) (the “Holder Notice Date”) and (y) the time of consummation of a
Subsequent Placement (in each case, other than with respect to Excluded Securities (as defined in the Securities Purchase Agreement))
(each, an “Eligible Subsequent Placement”), the Holder shall have the right, in its sole discretion, to require that
the Company redeem (each an “Subsequent Placement Optional Redemption”) all, or any portion, of the Conversion Amount
under this Note not in excess of (together with any Subsequent Placement Optional Redemption Amount (as defined in the applicable other
Note of the Holder) of any other Notes of the Holder) the Holder’s Holder Pro Rata Amount of 50% of the gross proceeds of such
Eligible Subsequent Placement (the “Eligible Subsequent Placement Optional Redemption Amount”) by delivering written
notice thereof (an “Subsequent Placement Optional Redemption Notice”) to the Company. Notwithstanding the foregoing,
if the Holder is participating in an Eligible Subsequent Placement, upon the written request of the Holder, the Company shall apply all,
or any part, as set forth in such written request, of any amounts that would otherwise be payable to the Holder in such Subsequent Placement
Optional Redemption, on a dollar-for-dollar basis, against the purchase price of the securities to be purchased by the Holder in such
Eligible Subsequent Placement.

 

(b)
Mechanics. Each Subsequent Placement Optional Redemption Notice shall indicate that all, or such applicable portion, as set forth
in the applicable Subsequent Placement Optional Redemption Notice, of the Eligible Subsequent Placement Optional Redemption Amount the
Holder is electing to have redeemed (the “Subsequent Placement Optional Redemption Amount”) and the date of such Subsequent
Placement Optional Redemption (the “Subsequent Placement Optional Redemption Date”), which shall be the later of (x)
the fifth (5th) Business Day after the date of the applicable Subsequent Placement Optional Redemption Notice and (y) the
date of the consummation of such Eligible Subsequent Placement. The portion of the Outstanding Value of this Note subject to redemption
pursuant to this Section 9 shall be redeemed by the Company in cash at a price equal to 115% of the Subsequent Placement Optional Redemption
Amount (the “Subsequent Placement Optional Redemption Price”). Redemptions required by this Section 9 shall be made
in accordance with the provisions of Section 13.

 

    	22

     

    

 

10.
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.

 

11.
RESERVATION OF AUTHORIZED SHARES.

 

(a)
Reservation. So long as any Notes remain outstanding, the Company shall at all times reserve the Required Reserve Amount (as defined
in the Securities Purchase Agreement). 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 Initial 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, notwithstanding Section 11(a), and not in limitation thereof, at any time while any of the
Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy
its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required
Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately use its reasonable best efforts
to take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company
to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as
soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after
the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase
in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with
a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of
Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. Notwithstanding the
foregoing, if any such time of an Authorized Share Failure, the Company is able to obtain the written consent of a majority of the shares
of its issued and outstanding shares of Common Stock to approve the increase in the number of authorized shares of Common Stock, the
Company may satisfy this obligation by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule
14C. In the event that the Company is prohibited from issuing shares of Common Stock pursuant to the terms of this Note due to the failure
by the Company to have sufficient shares of Common Stock available out of the authorized but unissued shares of Common Stock (such unavailable
number of shares of Common Stock, the “Authorized Failure Shares”), in lieu of delivering such Authorized Failure
Shares to the Holder, the Company shall pay cash in exchange for the redemption of such portion of the Conversion Amount convertible
into such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorized Failure Shares and
(y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date the Holder delivers
the applicable Conversion Notice with respect to such Authorized Failure Shares to the Company and ending on the date of such issuance
and payment under this Section 11(a); and (ii) to the extent the Holder purchases (in an open market transaction or otherwise) shares
of Common Stock to deliver in satisfaction of a sale by the Holder of Authorized Failure Shares, any brokerage commissions and other
out-of-pocket expenses, if any, of the Holder incurred in connection therewith. Nothing contained in Section 11(a) or this Section 11(b)
shall limit any obligations of the Company under any provision of the Securities Purchase Agreement.

 

    	23

     

    

 

12.
COMPANY OPTIONAL REDEMPTION.

 

(a)
At any time after date hereof 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
12 shall be redeemed by the Company in cash at a price (the “Company Optional Redemption Price”) equal to 132.5% of
the greater of (i) the sum of (A) the Conversion Amount being redeemed as of the Company Optional Redemption Date, (B) the applicable
Make-Whole Amount as of the Company Optional Redemption Date and (C) the Remaining Option Value of this Note as of the Company Optional
Redemption Date, (ii) the sum of (A) 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 12, (B) the applicable Make-Whole Amount
as of the Company Optional Redemption Date and (C) the Remaining Option Value of this Note as of the Company Optional Redemption Date.
The Company may exercise its right to require redemption under this Section 12 by delivering a written notice thereof by facsimile or
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 the Company Optional Redemption
shall occur (the “Company Optional Redemption Date”) which date shall not be less than ten (10) Trading Days nor more
than twenty (20) Trading Days following the Company Optional Redemption Notice Date, and (y) 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 12 (and analogous provisions under the Other Notes) on the Company Optional Redemption Date. Notwithstanding anything
herein to the contrary, 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 12 shall be made in accordance
with Section 13. In the event of the Company’s redemption of any portion of this Note under this Section, 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 12 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 this Section
12, then it must simultaneously take the same action with respect to all of the Other Notes.

 

    	24

     

    

 

13.
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. The
Company shall deliver the applicable Installment Redemption Price to the Holder in cash on the applicable Installment Date. The Company
shall deliver the applicable Subsequent Placement Optional Redemption Price to the Holder in cash on the applicable Subsequent Placement
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 Value of this Note 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 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 13, if applicable) minus (2) the Outstanding Principal Value 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) the greater of (x) the Floor Price and (y) 75% of the lowest Closing Bid Price of the Common

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

with any related interest or penalties) now or hereafter imposed or assessed against the Company and its Subsidiaries or their respective

and is continuing, (y) upon the occurrence and during the continuance 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 and be continuing,
the Company shall hire an independent, reputable investment bank selected by the Company and approved by the Required Holders, such approval
not to be unreasonably withheld or delayed, 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,

shall prohibit Lucid Diagnostics, any of its Subsidiaries or their respective boards of directors from taking any action or refraining
from taking any action to the extent the failure to take such action or failure to refrain from taking such action would be inconsistent
with applicable law or its fiduciary obligations under applicable law. Accordingly, the Holder agrees that no Event of Default shall
be deemed to have occurred as a result of Lucid Diagnostics, any of its Subsidiaries or any of their respective boards of directors so
taking any action or refraining from taking any action.

of Common Stock are to be determined for such Distributions (provided, however, that to the extent that the Holder’s right to participate
in any such Distribution 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 Distribution 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 Distribution (and beneficial ownership) to the extent of any such excess)
and the portion of such Distribution shall be held in abeyance for ninety (90) Trading Days for the benefit of the Holder until such
time or times during such abeyance period, 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 Distribution (and any Distributions declared
or made on such initial Distribution or on any subsequent Distribution held similarly in abeyance for additional ninety (90) Trading
Days) to the same extent as if there had been no such limitation). The Holder shall be deemed to have waived the right to receive any
such Distributions that remain held in abeyance at the end of such abeyance period if not granted prior to such time.
