SECURED
SUBORDINATED PROMISSORY NOTE





	$[_____________]	Original
    Issue Date: July 25, 2016


Amended:
November 29, 2016


 


FOR
VALUE RECEIVED, NXT-ID, INC., a Delaware corporation (“Borrower”), hereby promises to pay to the order of [___________________],
in its capacity as a Holder (“Holder,” which is sometimes referred to as the Subordinated Lender, per the definition
in Section 12(l)), pursuant to that certain Exchange Agreement dated November 29, 2016 (the “Exchange Agreement”),
the principal sum of [______________________]($[_________]) together with interest thereon as hereinafter described, in immediately
available funds, at such times as set forth below and in accordance with the terms set forth herein.


 


1.       Reference
to Purchase Agreement. This Secured Subordinated Promissory Note (this “Note”) is executed and delivered
pursuant to Exchange Agreement. Capitalized terms not otherwise defined herein shall have the meanings ascribed to them in
the Exchange Agreement. As used herein all references to the Purchase Agreement shall include the Exchange
Agreement.


 






     


     


    

 


2.       Payment
of Principal. Subject to the restrictions and limitations provided herein and in the Intercreditor Agreement, all outstanding
principal and accrued interest shall be due and payable in full on November 29, 2017, unless due sooner pursuant to the terms
hereof (the “Maturity Date”).


 


3.       Payment
of Interest.


 


(a)       Except
as otherwise provided herein, interest shall accrue from the original date of issuance of this Note on the unpaid principal amount
of this Note (the “Principal Balance”) at the rate of fifteen percent (15.0%) per annum (the “Interest Rate”),
which interest shall accrue on the original principal amount of the Note, even if the outstanding principal has been reduced by
conversion or otherwise. The accrued interest will be paid quarterly in Common Stock at the then in effect Conversion Price. On
the Maturity Date any accrued but unpaid interest is payable in cash by wire transfer of immediately available funds or at Holder’s
option, in shares of Common Stock at the then in effect Conversion Price. Interest due under this Note shall be calculated on
the basis of a 365-day year and the actual number of days elapsed in any portion of a month for which interest may be due.


 


(b)       From
and after an Event of Default (as defined herein), interest shall accrue on the amount of the Principal Balance hereunder at a
rate equal to the Interest Rate plus five percent (5.0%) per annum.


 


4.       Conversion.


 


(a)       Conversion
Generally. At any time after the Original Issue Date until all amounts due under this have been paid in full, this Note shall
be convertible, in whole or in part, into shares of Common Stock at the option of the Holder, at any time and from time to time
(subject to the conversion limitations set forth in Section 4(d) hereof). The Holder shall effect conversions by delivering
to the Company a Notice of Conversion, the form of which is attached hereto as Annex A (each, a “Notice of Conversion”),
specifying therein the principal amount of this Note and/or any other amounts due under this Note to be converted and the date
on which such conversion shall be effected (such date, the “Conversion Date”). If no Conversion Date is specified
in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered hereunder.
No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization)
of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall not be required to physically
surrender this Note to the Company unless the entire principal amount of this Note, all accrued and unpaid interest thereon and
all other amounts due under this Note have been so converted. Conversions hereunder shall have the effect of lowering the outstanding
principal amount of this Note in an amount equal to the applicable conversion amount. The Holder and the Company shall maintain
a Conversion Schedule showing the principal amount(s) and/or any other amounts due under this Note converted and the date of such
conversion(s). The Company may deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such
Notice of Conversion. In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative
in the absence of manifest error. The Holder, and any assignee by acceptance of this Note, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount
of this Note may be less than the amount stated on the face hereof.


 






    	 	2	 



     


    

 


(b)       Conversion
Price. The conversion price in effect on any Conversion Date shall be equal $3.00 (“Conversion Price”).
All such foregoing determinations will be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification
or similar transaction that proportionately decreases or increases the Common Stock. Nothing herein shall limit a Holder’s
right to pursue actual damages or declare an Event of Default pursuant to Section 8 hereof and the Holder shall have the right
to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant
to any other Section hereof or under applicable law.


 


(c)       Mechanics
of Conversion.


 


i.       Conversion
Shares Issuable Upon a Conversion. The number of Conversion Shares issuable upon a conversion hereunder shall be determined
by the quotient obtained by dividing (x) the sum of all outstanding (i) principal, (ii) interest, and (iii) any other amount
due under this Note to be converted as provided in the applicable Notice of Conversion by (y) the Conversion Price.


 






    	 	3	 



     


    

 


ii.       Delivery
of Certificate Upon Conversion. Not later than two (2) Trading Days after each Conversion Date (the “Share Delivery
Date”), the Company shall deliver, or cause to be delivered, to the Holder (A) a certificate or certificates representing
the Conversion Shares, which, on or after the date on which if the resale of such Conversion Shares are covered by and are being
sold pursuant to an effective Registration Statement or such Conversion Shares are eligible to be sold under Rule 144 without
the need for current public information and the Company has received an opinion of counsel to such effect reasonably acceptable
to the Company (which opinion the Company will be responsible for obtaining at its own cost) shall be free of restrictive legends
and trading restrictions (other than those which may then be required by the Purchase Agreement) representing the number of Conversion
Shares being acquired or being sold, as the case may be, upon the conversion of this Note, and (B) a bank check in the amount
of accrued and unpaid interest (if the Company has elected to pay accrued interest in cash). All certificate or certificates required
to be delivered by the Company under this Section 4(d) shall be delivered electronically through DTC or another established clearing
corporation performing similar functions, unless the Company or its Transfer Agent does not have an account with DTC and/or is
not participating in the DTC Fast Automated Securities Transfer Program; then, the Company shall issue and deliver to the address
as specified in such Notice of Conversion, a certificate (or certificates), registered in the name of the Holder or its designee,
for the number of Conversion Shares to which the Holder shall be entitled. If the Conversion Shares are not being sold pursuant
to an effective Registration Statement or if the Conversion Date is prior to the date on which such Conversion Shares are eligible
to be sold under Rule 144 without the need for current public information, the Conversion Shares shall bear a restrictive legend
in the following form, as appropriate:


 


“NEITHER
THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS.  THE SECURITIES
MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT
FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED
BY THE HOLDER), IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT
TO RULE 144 OR RULE 144A UNDER SAID ACT.  NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION
WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”


 


Notwithstanding
the foregoing, commencing on such date that the Conversion Shares are eligible for sale under Rule 144 subject to current public
information requirements, the Company, upon request and at the Company’s expense, shall obtain a legal opinion to allow
for such sales under Rule 144.


 


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


 






    	 	4	 



     


    

 


iv.       Obligation
Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion
of this Note in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the
Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any
Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or
alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law
by the Holder or any other Person, and irrespective of any other circumstance that might otherwise limit such obligation of the
Company to the Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery
shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the event the Holder
of this Note shall elect to convert any or all of the outstanding principal or interest amount hereof, the Company may not refuse
conversion based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation
of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining
conversion of all or part of this Note shall have been sought. If the injunction is not granted, the Company shall promptly comply
with all conversion obligations herein. If the injunction is obtained, the Company must post a surety bond for the benefit of
the Holder in the amount of 150% of the outstanding principal amount of this Note, which is subject to the injunction, which bond
shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall
be payable to the Holder to the extent it obtains judgment. In the absence of seeking such injunction, the Company shall issue
Conversion Shares or, if applicable, cash, upon a properly noticed conversion.


 


v.       Reservation
of Shares Issuable Upon Conversion. The Company covenants that it will at all times reserve and keep available out of its
authorized and unissued shares of Common Stock a number of shares of Common Stock at least equal 100% of the Required Minimum
for the sole purpose of issuance upon conversion of this Note and payment of interest on this Note, each as herein provided, free
from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder (and the other holders
of the Notes), not less than such aggregate number of shares of the Common Stock as shall (subject to the terms and conditions
set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 5, but ignoring
any Beneficial Ownership Limitations or other restrictions and/or limitations on conversions set forth herein or elsewhere) upon
the conversion of the then-outstanding principal amount of this Note and payment of interest hereunder. The Company covenants
that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and
nonassessable, and, at such times as a Registration Statement covering such shares is then effective under the Securities Act,
will be registered for public resale in accordance with such Registration Statement. For purposes of this Note, the “Required
Minimum” shall be defined as all outstanding debt plus interest and any fees divided by the Conversion Price or
the Alternate Conversion Price then in effect, as applicable. The Company shall be required to calculate the Required Minimum
on the first trading day of each month that the Note is outstanding and provide such calculation to the Holder and the transfer
agent promptly. For purposes of calculating the Required Minimum, Company shall assume that all then-outstanding principal will
remain outstanding until the Maturity Date and that all accrued but unpaid interest hereon accrues at the rate of 12% per annum
is paid on the Maturity Date and all amounts convert into shares of Common Stock at the Conversion Price or Alternate Conversion
Price then in effect.


 






    	 	5	 



     


    

 


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


 


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


 


(d)       Holder’s
Conversion Limitations. The Company shall not effect any conversion of principal and/or interest of this Note, and a Holder
shall not have the right to convert any principal and/or interest of this Note, to the extent that, after giving effect to the
conversion set forth on the applicable Notice of Conversion, the Holder (together with the Holder’s Affiliates, and any
Persons acting as a group together with the Holder or any of the Holder’s Affiliates) would beneficially own in excess of
the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the number of shares of
Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon
conversion of this Note with respect to which such determination is being made, but shall exclude the number of shares of Common
Stock that are issuable upon (i) conversion of the remaining, unconverted principal amount of this Note beneficially owned by
the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without
limitation, any other Notes) beneficially owned by the Holder or any of its Affiliates.  Except as set forth in the preceding
sentence, for purposes of this Section 4(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the
Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section
4(e) applies, the determination of whether this Note is convertible (in relation to other securities owned by the Holder together
with any Affiliates) and of which principal amount of this Note is convertible shall be in the sole discretion of the Holder,
and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether this Note may be
converted (in relation to other securities owned by the Holder together with any Affiliates) and which principal amount of this
Note is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction,
the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion
has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the
accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined
in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this
Section 4(d), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding
shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report
filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent
written notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding. 
Upon the written or oral request of a Holder, the Company shall within two (2) Trading Days confirm orally and in writing to the
Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the
Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial
Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving
effect to the issuance of shares of Common Stock issuable upon conversion of this Note held by the Holder. The Holder, upon not
less than 61 days’ prior written notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions
of this Section 4(d), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the
Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Note
held by the Holder and the Beneficial Ownership Limitation provisions of this Section 4(d) shall continue to apply. Any such increase
or decrease will not be effective until the 61st day after such notice is delivered to the Company. The Beneficial
Ownership Limitation provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity
with the terms of this Section 4(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Note.

Section
5.Certain Adjustments.


 


(a)       Stock
Dividends and Stock Splits. If the Company, at any time while this Note is outstanding: (i) pays a stock dividend or otherwise
makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock Equivalents
(which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon conversion of, or payment
of interest on, the Notes), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines
(including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues,
in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company, then the Conversion
Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury
shares of the Company) outstanding immediately before such event, and of which the denominator shall be the number of shares of
Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section shall become effective immediately
after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision, combination or reclassification.


 


(b)       Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 5(a) above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares 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 that 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 regard to
any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before 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, to the extent that the Holder’s right to participate in any such Purchase Right would
result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such
Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such
extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right
thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).


 






    	 	7	 



     


    

 


(c)       Pro
Rata Distributions. During such time as this Note is outstanding, if the Company shall declare or make any dividend or other
distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital
or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of
a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”),
at any time after the issuance of this Note, then, in each such case, the Holder shall be entitled to participate in such Distribution
to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock
acquirable upon complete exercise of this Note (without regard to any limitations on exercise hereof, including without limitation,
the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, 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 participation
in such Distribution (provided, however, to the extent that the Holder's right to participate in any such Distribution
would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate
in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution
to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time,
if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation.


 


(d)       Fundamental
Transaction. The Company shall not, directly or indirectly, in one or more related transactions, effect any merger or consolidation
of the Company and/or or any of its Subsidiaries with and/or into another Person, without the express written consent of 90% of
the then-issued and outstanding principal amount of Notes (the “90% Amount”). If, subject to the Company obtaining
written consent of the 90% Amount, at any time while this Note is outstanding (i) the Company, directly or indirectly, in one
or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of
the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is
effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in
one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person, whereby such other Person
acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person
or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share
purchase agreement or other business combination) (each, a “Fundamental Transaction”), then, upon any subsequent
conversion of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon
such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section
4(e) on the conversion of this Note), the number of shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note
is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 4(e) on the conversion
of this Note). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted
to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of
Common Stock in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration
in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of
Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the
Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following
such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is
not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under
this Note and the other Documents (as defined in the Purchase Agreement) in accordance with the provisions of this Section 5(e)
pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without
unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Note, deliver to the
Holder in exchange for this Note a security of the Successor Entity evidenced by a written instrument substantially similar in
form and substance to this Note that is convertible for a corresponding number of shares of capital stock of such Successor Entity
(or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon conversion of this Note (without
regard to any limitations on the conversion of this Note) prior to such Fundamental Transaction, and with a conversion price which
applies the conversion price hereunder to such shares of capital stock (but taking into account the relative value of the shares
of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares
of capital stock and such conversion price being for the purpose of protecting the economic value of this Note immediately prior
to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder.
Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that
from and after the date of such Fundamental Transaction, the provisions of this Note and the other 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 Documents with the same effect as if such Successor
Entity had been named as the Company herein.

(e)       Calculations.
All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.
For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall
be the sum of the number of shares of Common Stock (excluding any treasury shares of the Company) issued and outstanding.


 


(f)       Notice
to the Holder.


 


i.       Adjustment
to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall
promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.


 


ii.       Notice
to Allow Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on
the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C)
the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase
any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required
in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any
sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common
Stock is converted into other securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding-up of the affairs of the Company, then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Note, and shall cause to be delivered to the Holder at its last address
as it shall appear upon the Note Register, at least twenty (20) calendar days prior to the applicable record or effective date
hereinafter specified, a notice, stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record
to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which

(b)       Failure

any of its rights or remedies hereunder unless such waiver be in writing and signed by Subordinated Lender, and then only to the
extent specifically set forth therein. A waiver in connection with one event shall not be construed as continuing or as a bar
to or waiver of any right or remedy in connection with a subsequent event.

any guarantor and all others now liable for all or any part of the obligations evidenced hereby.


 


(d)       All
payments made on account of the indebtedness evidenced by this Note shall be made in currency and coin of the United States of
America which shall be legal tender for public and private debts at the time of payment. Said payments and prepayments are to
be made via wire transfer pursuant to Subordinated Lender’s instructions, or at such place as Subordinated Lender may, from
time to time, in writing appoint.


 


(e)       Reserved.


 


(f)       Time
is of the essence hereof.

an Event of Default, Borrower shall permit Subordinated Lender, its representatives and agents, upon reasonable notice and during
normal business hours, to (i) visit and inspect any of the properties of Borrower, (ii) examine the corporate and financial records
of Borrower and make copies thereof or extracts therefrom and (iii) discuss the affairs, finances and accounts of any such corporations
with the directors, officers, managers, key employees, consultants and independent accountants of Borrower.

Note and the rights and obligations of all parties hereunder shall be governed, construed and enforced in accordance with the

(i)       The
parties hereto intend and believe that each provision in this Note comports with all applicable law. However, if any provision
of this Note is found by a court of law to be in violation of any applicable law, and if such court should declare such provision
of this Note to be unlawful, void or unenforceable as written, then it is the intent of all parties hereto that such provisions
shall be given full force and effect to the fullest possible extent that it is legal, valid and enforceable, then the remainder
of this Note shall be construed as if such unlawful, void or unenforceable provision were not contained therein, and that the
rights, obligations and interests of Borrower and Subordinated Lender under the remainder of this Note shall continue in full
force and effect.


 


(j)       To
induce Subordinated Lender to accept this Note, Borrower irrevocably agrees that, subject to Subordinated Lender’s sole
and absolute discretion, all actions or proceedings in any way, manner or respect, arising out of, from or related to this Note
or the Security Agreement shall be litigated in courts having situs within Cook County, Illinois. Borrower hereby consents and
submits to the jurisdiction of any local, state or federal court located within said county. Borrower hereby waives any right
it may have to transfer or change the venue of any litigation brought against Borrower by Subordinated Lender in accordance with

representatives, executors, administrators, devisees, legatees and heirs.


 


(m)       All
notices, requests, demands and other communications between the parties required or permitted to be given hereunder shall be given
in the manner set forth in the Purchase Agreement.


 






    	 	13	 



     


    

 


(n)       The
non-prevailing party shall pay to the prevailing party the reasonable costs and expenses (including, without limitation, reasonable
attorneys’ fees) incurred by the prevailing party in any litigation, contest, dispute, suit, proceeding or action in any
way relating to this Note or any attempt by Subordinated Lender to enforce its rights against Borrower by virtue of this Note.


 


(o)       It
is the intention of the Borrower and the Subordinated Lender to conform strictly to all applicable usury laws now or hereafter
in force, and any interest payable under this Note shall be subject to reduction to the amount not in excess of the maximum legal
amount allowed under the applicable usury laws as now or hereafter construed by the courts having jurisdiction over such matters.
If the maturity of this Note is accelerated by reason of an election by the Subordinated Lender hereof resulting from an Event
of Default, voluntary prepayment by the Borrower or otherwise, then earned interest may never include more than the maximum amount
permitted by law, computed from the date hereof until payment, and any interest in excess of the maximum amount permitted by law
shall be canceled automatically and, if theretofore paid, shall at the option of the Subordinated Lender hereof either be rebated
to the Borrower or credited on the outstanding principal amount of this Note, or if this Note has been paid, then the excess shall
be rebated to the Borrower. The aggregate of all interest (whether designated as interest, service charges, points or otherwise)
contracted for, chargeable, or receivable under this Note shall under no circumstances exceed the maximum legal rate upon the
unpaid principal balance of this Note remaining unpaid from time to time. If such interest does exceed the maximum legal rate,
it shall be deemed a mistake and such excess shall be canceled automatically and, if theretofore paid, rebated to the Borrower
or credited on the outstanding principal amount of this Note, or if this Note has been repaid, then such excess shall be rebated
to the Borrower.

    	 	A-3	 



     


    

 


Borrower
will from time to time execute or cause to be executed such additional security agreements, financing statements, renewals thereof
and other documents (and pay the cost of filing
and recording the same in all public offices reasonably deemed necessary by Subordinated Lender) and do such other acts (including
the deposit with Subordinated Lender of any certificate of title issuable with respect to the Collateral, with an official notation
thereon of the security interest hereunder) to establish, maintain and evidence Subordinated Lender’s subordinated security
interest in the Collateral, free of all other liens and claims other than the Subordinated Note, the Senior Loan Agreement and
the Permitted Liens. Borrower agrees that a carbon, photographic or photostatic copy, or other reproduction, of this Agreement
or of any financing statement, shall be sufficient to evidence Subordinated Lender’s security interest. Borrower hereby
irrevocably authorizes Subordinated Lender at any time, and from time to time, to file in any jurisdiction any initial financing
statements and amendments thereto without the signature or consent of Borrower that (i) indicate the Collateral (A) is comprised
of all assets of Borrower or words of similar effect, regardless of whether any particular asset comprising a part of the Collateral
falls within the scope of Article 9 of the Uniform Commercial Code of the jurisdiction wherein such financing statement or amendment
is filed, or (B) as being of an equal or lesser scope or within greater detail as the grant of the security interest set forth

statement or amendment. Borrower further ratifies and affirms its authorization for any financing statements and/or amendments
thereto, executed and filed by Subordinated Lender in any jurisdiction prior to the date of this Agreement. In addition, Borrower

will at all times until satisfaction in full of the Secured Liabilities, cause the Collateral to be insured against risks of fire,
vandalism, theft, and other such risks as Lender may reasonably require in the amount of its full insurable value with an insurer
or insurers reasonably acceptable to Subordinated Lender, subject to the rights of Senior Lender. Subject to the rights of Senior
Lender under the Senior Loan Agreement and the Intercreditor Agreement, Borrower will forthwith remit to Subordinated Lender,
in the form received, with any endorsements necessary to effect payment thereof to Subordinated Lender, any proceeds of insurance
required or maintained pursuant to this Agreement which Borrower, or any affiliate of Borrower may receive or which Borrower and
any other party or parties may receive. All policies of insurance shall contain a standard lender loss payable clause in favor
of Subordinated Lender, shall provide that Subordinated Lender’s interest therein shall not be invalidated by the act, omission
or neglect of anyone other than Subordinated Lender and for at least ten (10) days’ prior written notice of cancellation
to Subordinated Lender. Borrower shall furnish Subordinated Lender with evidence of such insurance or other evidence reasonably
satisfactory to Subordinated Lender as to compliance with the provisions of this paragraph prior to the expiration or cancellation
of any such insurance. Subject to the Intercreditor Agreement and the rights of Senior Lender, Subordinated Lender may act as
attorney in fact for Borrower in making, adjusting and settling claims under and canceling such insurance and endorsing Borrower’s
name on any drafts drawn by insurers of the Collateral. If Borrower shall fail to provide such insurance or fail to renew the
same upon expiration thereof, Borrower agrees that Subordinated Lender, at the sole cost of Borrower, may obtain such insurance
as Subordinated Lender shall deem reasonably appropriate, and the entire cost thereof shall be added to the Secured Liabilities.

(i)       As
used herein, “full insurable value” means the actual replacement cost of the Collateral (without taking into account
any depreciation), determined annually by an insurer or by Borrower or, at the request of Subordinated Lender, by an independent
insurance broker (subject to Subordinated Lender’s reasonable approval) including an endorsement covering acts of municipal
authorities including increased cost of construction and demolition.


 


(j)       Following
the occurrence of a Default and subject to the Intercreditor Agreement and the rights of the Senior Lender set forth in the Senior
Loan Agreement, Subordinated Lender from time to time may (but shall not be obligated to), pay any amount or perform any act which
Borrower has agreed to do hereunder and which Borrower shall have failed to do. All moneys so advanced and expenses so incurred
by Subordinated Lender shall be immediately due and payable and shall be added to the Secured Liabilities if not paid within five
(5) days following Subordinated Lender’s demand therefor.


 


6.       Defaults
and Remedies. (a) Borrower, without notice or demand of any kind, shall be in default under this Agreement upon the occurrence
of any of the following events (each a “Default”):

of Secured Liabilities. Any amount due and owing on any of the Secured Liabilities, whether by its terms or as otherwise provided
herein, is not paid when due.


 


(ii)       Misrepresentation.
Any oral or written warranty, representation,
certificate or statement of Borrower in this Agreement, the Purchase Agreement, any of the Subordinated Note or any other agreement
with Subordinated Lender shall be false when made or at any time thereafter, or if any financial data or any other information
now or hereafter furnished to Subordinated Lender by or on behalf of Borrower shall prove to be false, inaccurate or misleading
in any material respect.


 


(iii)       Nonperformance.
Any failure to perform or default in the performance
of any covenant, condition or agreement contained in this Agreement, or in any of the Subordinated Note any other agreement with
Subordinated Lender.


 


(iv)       Bankruptcy,
Insolvency, Etc. Borrower becomes insolvent or generally fails to pay, or admits in writing its inability or refusal to pay,
debts as they become due, or Borrower applies for, consents to, or acquiesces in the appointment of a trustee, receiver or other
custodian for itself or any property thereof, or makes a general assignment for the benefit of creditors; or, in the absence of
such application, consent or acquiescence, a trustee, receiver
or other custodian is appointed for Borrower or for a substantial part of the property of any thereof and is not discharged within
thirty (30) days, or any bankruptcy, reorganization, debt arrangement, or other case or proceeding under any bankruptcy or insolvency
law, or any dissolution or liquidation proceeding, is commenced in respect of Borrower, and if such case or proceeding is not
commenced by Borrower, it is consented to or acquiesced in by Borrower, or remains undismissed for thirty (30) days; or Borrower
takes any action to authorize, or in furtherance of, any of the foregoing.


 






    	 	A-5	 



     


    

 


(v)       Judgments.

Borrower which is not fully covered by insurance.


 


(vi)       Collateral
Impairment. The entry of any judgment, decree, levy, attachment, garnishment or other process, or the filing of any lien against,
any of the Collateral or any collateral under a separate security agreement securing any of the Secured Liabilities and such judgment
or other process shall not have been, within thirty (30) days from the entry thereof, (A) bonded over to the satisfaction of Subordinated
Lender and appealed, (B) vacated, or (C) discharged, or the loss, theft, destruction, seizure or forfeiture, or the occurrence
of any deterioration or impairment of any of the Collateral or any of the collateral under any security agreement securing any
of the Secured Liabilities, or any decline or depreciation in the value or market price thereof (whether actual or reasonably
anticipated), which causes the Collateral in the sole opinion of Subordinated Lender acting in good faith, to become unsatisfactory
as to value or character, or which causes Subordinated Lender to reasonably believe that it is insecure and that the likelihood
for repayment of the Secured Liabilities is or will soon be impaired, time being of the essence. The cause of such deterioration,
impairment, decline or depreciation shall include, but is not limited to, the failure by Borrower to do any act deemed necessary
by Subordinated Lender to preserve and maintain the value and collectability of the Collateral.


 


(b)       If
a Default exists Subordinated Lender shall immediately notify Senior Lender in writing, then at the election of Subordinated Lender,
subject to the Intercreditor Agreement and the rights of the Senior Lender, and without further demand or notice of any kind,
Subordinated Lender may declare all of the Secured Liabilities to be immediately due and payable and exercise from time to time
any rights and remedies available to Subordinated Lender under the laws of the State of Illinois in order to collect the Secured
Liabilities. Subject to the Intercreditor Agreement, Borrower shall, in such event, and if Subordinated Lender so requests, assemble
the Collateral, at the expense of Borrower, at a convenient place designated by Subordinated Lender. At any sale held pursuant
hereto, Subordinated Lender shall be authorized to bid in the amount of the Secured Liabilities, or so much thereof as Subordinated
Lender, in its reasonable discretion, shall deem appropriate, at such sale. Subordinated Lender shall not be liable nor accountable
to Borrower if less than the entire amount of the Secured Liabilities shall be so bid. Borrower shall pay all expenses incurred
by Subordinated Lender in the collection of such indebtedness, including reasonable attorneys’ fees and legal expenses,
and in the repair of any real estate or other property to which any of the Collateral may be affixed. If any notification of intended
disposition of any of the Collateral is required by law, such notification shall be deemed commercially
reasonable and proper if given at least ten (10) days before such disposition. Any proceeds of the disposition of any of the Collateral
may be applied by Subordinated Lender to the payment of the reasonable expenses of retaking, holding, preparing for sale and selling
the Collateral, including reasonable attorneys’ fees and legal expenses, and any balance of such proceeds may be applied
by Subordinated Lender toward the payment of such of the indebtedness, and in such order of application, as Subordinated Lender
may from time to time elect.

(c)       No
delay or omission on the part of Subordinated Lender in the exercise of any right or remedy shall operate as a waiver thereof.
The remedies available to Subordinated Lender under this Agreement shall be exercisable in any combination whatsoever and shall
be in addition to, and exercisable in any combination, any and all remedies available by operation of law and under the Subordinated
Note.


 


7.       Waiver.
No delay on Subordinated Lender’s part in exercising any power of sale, lien, option or other right hereunder, and no notice
or demand which may be given to or made upon Borrower by Subordinated Lender with respect to any power of sale, lien, option or
other right hereunder, shall constitute a waiver thereof, or limit or impair Subordinated Lender’s right to take any action
or to exercise any power of sale, lien, option, or any other right hereunder, without notice or demand, or prejudice Subordinated
Lender’s rights as against Borrower in any respect.


 


8.       Assignment.
Borrower shall not assign or transfer this Agreement, either voluntarily, by operation of law, by merger or stock sale or
otherwise, without the prior written consent of Subordinated Lender.


 


9.       Termination.
Upon the indefeasible payment in full of all Secured Liabilities Subordinated Lender shall release the security interest granted
to Subordinated Lender pursuant to this Agreement and, except as otherwise provided herein, all of Borrower’s obligations
hereunder shall at such time terminate.


 


10.       Lien
Absolute. All rights of Subordinated Lender hereunder, and all obligations of Borrower hereunder, shall be absolute and unconditional
irrespective of:


 


(a)       any
lack of validity or enforceability of any of the Subordinated Note or any other agreement or instrument governing or evidencing
any Secured Liabilities;


 


(b)       any
change in the time, manner or place of payment of, or in any other term of, all or any part of the Secured Liabilities, or any
other amendment or waiver of or any consent to any departure from any of the Subordinated Note or any other agreement or instrument
governing or evidencing any Secured Liabilities;


 


(c)       any
exchange, release or non-perfection of any other collateral, or any release or amendment or waiver of or consent to departure
from any guaranty, for all or any of the Secured Liabilities; or


 


(d)       any
other circumstance which might otherwise constitute a defense available to, or a discharge of, Borrower.


 






    	 	A-7	 



     


    

 


11.       Release.
Borrower consents and agrees that Subordinated
Lender may at any time, or from time to time, in its discretion (a) renew, extend or change the time of payment, and/or the manner,
place or terms of payment of all or any part of the Secured Liabilities and (b) exchange, release and/or surrender all or any
of the Collateral, or any part thereof, by whomsoever deposited, which is now or may hereafter be held by Subordinated Lender
in connection with all or any of the Secured Liabilities, all in such manner and upon such terms as Subordinated Lender may deem
proper, and without notice to or further assent from Borrower, it being hereby agreed that Borrower shall be and remains bound
under this Agreement, irrespective of the value or condition of any of the Collateral, and notwithstanding any such change, exchange,
settlement, compromise, surrender, release, renewal or extension, and notwithstanding also that the Secured Liabilities may, at
any time, exceed the aggregate principal amount thereof set forth in the Subordinated Note, or any other agreement governing any
Secured Liabilities. Borrower hereby waives notice of acceptance of this Agreement, and also presentment, demand, protest and
notice of dishonor of any and all of the Secured Liabilities, and promptness in commencing suit against any party hereto or liable
hereon, and, except as otherwise provided herein, in giving any notice to or of making any claim or demand hereunder upon Borrower.
No act or omission of any kind on Subordinated Lender’s part shall in any event affect or impair this Agreement unless such
act or omission constitutes the willful misconduct of Subordinated Lender or any of its agents.


 


12.       Reinstatement.
This Agreement shall remain in full force and
effect and continue to be effective should any petition be filed by or against Borrower for liquidation or reorganization, should
Borrower become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for
all or any significant part of Borrower’s assets, and shall continue to be effective or be reinstated, as the case may be,
if at any time payment and performance of the Secured Liabilities, or any part thereof, is, pursuant to applicable law, rescinded
or reduced in amount, or must otherwise be restored or returned by any obligee of the Secured Liabilities, whether as a “voidable
preference,” “fraudulent conveyance” or otherwise, all as though such payment or performance had not been made.
In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Secured Liabilities shall
be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.


 


13.       Supplemental
Reports. Borrower shall immediately upon receipt thereof, provide to Subordinated Lender copies of any reports submitted by
Borrower to the Senior Lender pursuant to the Senior Loan Agreement or related agreements.


 


14.       Waiver
of Claims. Borrower acknowledges, agrees and affirms that Borrower possesses no claims, defenses, offsets, recoupment or counterclaims
of any kind or nature against Subordinated Lender or with respect to the enforcement of any of the Subordinated Note, as amended
or modified hereby (collectively, the “Claims”). Borrower further acknowledges and agrees that it has no knowledge
of any facts that would or might give rise to any Claims. If facts now exist which would or could give rise to any Claim against
Subordinated Lender or with respect to the enforcement of any of the Subordinated Note, as amended or modified hereby, Borrower
hereby unconditionally, irrevocably and unequivocally waives and fully releases any and all such Claims as if such Claims were
the subject of a lawsuit, adjudicated to final judgment from which no appeal could be taken and therein dismissed with prejudice.


 


15.Miscellaneous.


 


(a)       Subordinated
Lender may execute any of its duties hereunder by or through agents or employees and shall be entitled to the advice of counsel
concerning all matters pertaining to its duties hereunder.


 






    	 	A-8	 



     


    

 


(b)       Borrower
agrees to promptly reimburse Subordinated Lender for actual out-of-pocket expenses, including, without limitation, reasonable
counsel fees, incurred by Subordinated Lender or the Sellers in connection with the enforcement of Subordinated Lender’s
rights under this Agreement.


 


(c)       Neither
Subordinated Lender nor any of its managers, members, officers, directors, employees, agents or counsel shall be liable for any
action lawfully taken or omitted to be taken by it or them hereunder or in connection herewith, except for its or their own gross
negligence or willful misconduct.


 


(d)       THIS
AGREEMENT SHALL BE BINDING UPON BORROWER AND ITS SUCCESSORS AND ASSIGNS, AND SHALL INURE TO THE BENEFIT OF, AND BE ENFORCEABLE
BY, SUBORDINATED LENDER, AND ITS SUCCESSORS AND ASSIGNS, AND SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE INTERNAL LAWS IN EFFECT IN THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICT OF LAWS, AND NONE OF THE
TERMS OR PROVISIONS OF THIS AGREEMENT MAY BE WAIVED, ALTERED, MODIFIED OR AMENDED EXCEPT IN WRITING DULY SIGNED FOR AND ON BEHALF
OF SUBORDINATED LENDER AND BORROWER.


 


16.       Severability.
If for any reason any provision or provisions hereof are determined to
be invalid and contrary to any existing or future law, such invalidity shall not impair or affect the operation of those portions
of this Agreement which are valid.


 


17.       Notice.
All notices, requests, demands and other communications between the parties
required or permitted to be given hereunder shall be given in the manner set forth in the Purchase Agreement.


 


18.       Section
Titles. The Section titles contained in this Agreement are and shall be without substantive meaning or content of any kind
whatsoever and are not a part of the agreement between the parties hereto.


 


19.       WAIVER
OF JURY TRIAL. SUBORDINATED LENDER AND BORROWER, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, EACH
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY, ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE
OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT, THE SUBORDINATED NOTE, ANY OF THE OTHER OBLIGATIONS, THE COLLATERAL, OR ANY AMENDMENT,
INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING
FROM ANY LENDING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, OR ANY COURSE OF CONDUCT OR COURSE OF DEALING
IN WHICH SUBORDINATED LENDER AND BORROWER ARE ADVERSE PARTIES, AND EACH AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED
BEFORE A COURT AND NOT BEFORE A JURY. Except as prohibited by law, Borrower waives any right which it may have to claim or recover
in any litigation referred to in the preceding sentence any special, exemplary, punitive or consequential damages or any damages
other than, or in addition to, actual damages. Borrower (i) certifies that neither Subordinated Lender nor any representative,
agent or attorney of Subordinated Lender has represented, expressly or otherwise, that Subordinated Lender would not, in the event
of litigation, seek to enforce the foregoing waivers, and (ii) acknowledges that, in entering into this Agreement and the Subordinated
Note, Subordinated Lender is relying upon, among other things, the waivers and certifications contained in this Section.


 


20.       Counterparts.
