and such default shall not have been cured or waived in writing by or on behalf of the requisite percentage of the holders of such

(b)            The
Company may not, directly or indirectly, make, and the Holder may not ask, demand, take or receive from or on behalf of the Company,
any payment on account of the principal of or interest on this Note during the period (a “Deferral Period”)

(i)            the
existence of a Payment Default; or

time an effective Deferral Notice is given and (z) if any such Deferral Notice has been given, no subsequent Deferral Notice with
respect to any number of different Payment Defaults or Specified Covenant Defaults shall be effective until the later of (1) the
date such subsequent Deferral Notice is received by the Company and the holders of Subordinated Notes and (2) the three hundred
sixty-fifth (365th) day after receipt of the then most recent prior effective Deferral Notice. So long as any Senior

notice of any proposed demand for payment or institution of proceedings with respect to this Note (which notice may be given during
a Deferral Period provided that the proposed demand for payment is not to be made or the proposed proceedings are not to be instituted
until the expiration of such Deferral Period).


 


(c)            Upon
termination of any Deferral Period the Company shall resume payments on account of the principal of and interest on this Note subject
to the obligation of the Company and the Holder to pay over to the holders of Senior Indebtedness amounts otherwise payable on
account of the principal of and interest on this Note pursuant to the provisions of, and in the circumstances specified in, this
Section 4.


 


(d)            During

shall be instituted against the Company and such proceeding remains undismissed for a period of sixty (60) days. So long as any
Senior Indebtedness is outstanding, the Holder shall give the holders of the Senior Indebtedness five (5) Business Days’

provided that the proposed acceleration is not to be effective until the expiration of such Deferral Period).


 



    	-7-



    	 



    

(e)            In
the event that, notwithstanding the foregoing provisions of this Section 4.3, any payment shall be made by or on behalf
of the Company and received by the Holder at a time after the giving of a Deferral Notice and during a Deferral Period, then such
payment shall be held in trust for the benefit of and shall be immediately paid over to the holders of Senior Indebtedness remaining
unpaid or their respective Representatives, for application to the payment in full of all Senior Indebtedness in accordance with
its terms (after giving effect to any prior or substantially concurrent payment to the holders of such Senior Indebtedness).


 


4.4            Subrogation
to Rights of Holders of Senior Indebtedness. After all amounts payable under or in respect of Senior Indebtedness are paid
in full, the Holder shall be subrogated to the extent of the payments or distributions made to the holders of, or otherwise applied
to payment of, such Senior Indebtedness pursuant to the provisions of this Section 4 (equally and ratably with the
holders of all indebtedness of the Company which by its express terms is subordinate and subject in right of payment to Senior
Indebtedness to substantially the same extent as this Note is so subordinate and subject in right of payment and which is entitled
to like rights of subrogation), to the rights of the holders of such Senior Indebtedness (or their respective Representatives)
to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal
of and interest on this Note shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders
of the Senior Indebtedness (or their respective Representatives) of any cash, property or securities to which the Holder would
be entitled except for the provisions of this Section 4, and no payments over pursuant to the provisions of this Section 4
to the holders of Senior Indebtedness (or their respective Representatives) by the Company or the Holder shall, as among the Company
and its creditors (other than holders of Senior Indebtedness and the Holder), be deemed to be a payment or distribution by the
Company to or on account of Senior Indebtedness it being understood that the provisions of this Section 4 are solely
for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand and the Holder on the other
hand.


 


If any payment
or distribution to which the Holder would otherwise have been entitled but for the provisions of this Section 4 shall
have been applied, pursuant to the provisions of this Section 4, to the payment of all amounts payable under the Senior
Indebtedness, then and in such case, the Holder shall be entitled to receive (equally and ratably with the holders of all indebtedness
of the Company which by its express terms is subordinate and subject in right of payment to Senior Indebtedness to substantially
the same extent as this Note is subordinate and subject in right of payment and which is entitled to like rights) from the holders
of such Senior Indebtedness (or their respective Representatives) any substantially contemporaneous payments or distributions received
by such holders of Senior Indebtedness (or their respective Representatives) in excess of the amount sufficient to pay in full
all obligations payable under or in respect of such Senior Indebtedness.


 



    	-8-



    	 



    

4.5            Rights
of Holders Not to Be Impaired. Nothing contained in this Section 4 or elsewhere in this Note is intended to
or shall:


 


(a)            impair,
as among the Company, its creditors other than holders or Senior Indebtedness and the Holder, the obligation of the Company, which
is absolute and unconditional, to pay to the Holder the principal of and premium, if any, and interest on this Note as and when
the same shall become due and payable in accordance with their terms; or


 


(b)            affect
the relative rights against the Company of the Holder of this Note and creditors of the Company other than the holders of Senior
Indebtedness; or


 


(c)            prevent
the Holder from exercising all remedies otherwise permitted by applicable law upon default subject to the rights, if any, under
this Section 4 of the holders of Senior Indebtedness to receive payments or distributions otherwise payable or deliverable
to, or received by, such holder upon the exercise of any such remedy and subject to the restriction on acceleration set forth in
Section 4.3(d).


 


4.6            Effectuation
of Subordination. If the Holder does not file a proper claim or proof of debt in the form required in any Insolvency or
Liquidation Proceeding prior to thirty (30) days before the expiration of the time to file such claims or proofs, then the holders
of the Senior Indebtedness, or their Representatives, are hereby authorized, and shall have the right (without any duty), to file
an appropriate claim for and on behalf of such holder.


 


4.7            No
Waiver of Subordination Provisions. No right of any present or future holder of any Senior Indebtedness, or Representative
thereof, to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure
to act on the part of the Company or by any act or failure to act by any such holder or Representative thereof, or by any noncompliance
by the Company with the terms, provisions and covenants of this Note regardless of any knowledge thereof which any such holder
or Representative thereof may have or be otherwise charged with.


 


Without in
any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness (or their Representatives, if applicable)
may, at any time and from time to time, without the consent of or notice to the Holder, without incurring responsibility to the
Holder and without impairing or releasing the subordination and other benefits provided in this Section 4 or the obligations
hereunder of the Holder to the holders of Senior Indebtedness, do any one or more of the following all without notice to the Holder
and even if any right of reimbursement or subrogation or other right or remedy of the Holder is affected, impaired or extinguished
thereby:


 



    	-9-



    	 



    

(a)            change
the manner, place or terms of payment or change or extend the time of payment of, or renew, exchange, amend or alter, the terms
of any Senior Indebtedness, any security therefor or guaranty thereof or any liability of the Company or any guarantor to such
holder, or any liability incurred directly or indirectly in respect thereof, or otherwise amend, renew, exchange, modify or supplement
in any manner Senior Indebtedness or any instrument evidencing or guaranteeing or securing the same or any agreement under which
Senior Indebtedness is outstanding;


 


(b)            sell,
exchange, release, surrender, realize upon, enforce or otherwise deal with in any manner and any order any property pledged, mortgaged
or otherwise securing Senior Indebtedness or any liability of the Company or any guarantor to such holder, or any liability incurred
directly or indirectly in respect thereof;


 


(c)            settle
or compromise any Senior Indebtedness or any other liability of the Company or any guarantor of the Senior Indebtedness to such
holder or any security therefor or any liability incurred directly or indirectly in respect thereof and apply any sums by whomsoever
paid and however realized to any liability (including, without limitation, Senior Indebtedness) in any manner or order; and


 


(d)            fail
to take or to record or otherwise perfect, for any reason or for no reason, any lien or security interest securing Senior Indebtedness
by whomsoever granted, exercise or delay in or refrain from exercising any right or remedy against the Company or any security
or any guarantor or any other person, elect any remedy and otherwise deal freely with the Company and any security and any guarantor
of the Senior Indebtedness or any liability of the Company or any guarantor to such holder or any liability incurred directly or
indirectly in respect thereof.


 


4.8            Reliance
on Court Orders; Evidence of Status. Upon any payment or distribution of assets of the Company referred to in Section 4.2,
the Holder shall be entitled to rely upon a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other
person making such payment or distribution delivered to the Holder for the purpose of ascertaining the persons entitled to participate
in such payment or distribution, the holders of Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Section 4.


 


In the absence
of any such receiver, trustee in bankruptcy, liquidating trustee, agent or other person, the holder of this Note shall be entitled
to rely upon a written notice by a person representing himself to be a holder of Senior Indebtedness (or a Representative on behalf
of such holder) as evidence that such person is a holder of Senior Indebtedness (or is such a Representative) for any relevant
purpose. In the event that any holder determines in good faith that further evidence is required with respect to the right of any
person as a holder of Senior Indebtedness (or such a Representative), as to the extent to which such person is entitled to participate
in such payment or distribution, and as to other facts pertinent to the rights of such person under this Section 4,
such holder may request such person to furnish evidence to the reasonable satisfaction of such holder as to the amount of Senior
Indebtedness held by such person, the extent to which such person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such person under this Section 4, and if such evidence is not furnished
such holder may defer (without liability to any holder of Senior Indebtedness or any Representative of such holder) any payment
to such person pending judicial determination as to the right of such person to receive such payment or until such time as such
holder shall be otherwise satisfied as to the right of such person to receive such payment.

to Prevent Events of Default. The failure to make a payment on account of the principal of or interest on this Note by
reason of any provision of this Section 4 shall not be construed as preventing the occurrence of a default or an Event
of Default under this Note. Except as expressly provided in Section 4.3(d), nothing in this Section 4 shall
affect the rights of the Holder to accelerate the maturity of this Note in accordance with its terms.


 


4.10            Amendments.
Without the prior written consent of the holders of the Senior Indebtedness, the Company and the Holder shall not amend, supplement
or otherwise modify any provision of this Section 4 if such amendment would have a material adverse effect on the holders

(a)            the
Company shall default in the payment of any part of the principal of this Note or the other Notes;


 


(b)            the
Company shall default in the payment of any installment of interest on this Note or the other Notes for more than fifteen (15)
days after the same shall become due and payable;


 


(c)            the
Company shall breach or default in the performance of any covenant or warranty of the Company in this Note, and continuance of
such breach for a period of thirty (30) days after there has been given, by registered or certified mail, to the Company by the
holder of this Note, a written notice specifying such breach or default and requiring it to be remedied;


 


(d)            a
court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company in an involuntary

assignee, custodian, trustee, sequestrator (or similar official) of the Company or for any substantial part of its property, or
ordering the winding-up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period

    	-11-



    	 



    

(e)            the
Company shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect,
shall consent to the entry of an order for relief in an involuntary case under any such law, or shall consent to the appointment
of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of the
Company or for any substantial part of its property, or shall make any general assignment for the benefit of creditors, or shall
fail generally to pay its debts as they become due, or shall take any corporate action in furtherance of any of the foregoing;


 


then and in any such event the
Holder of this Note may at any time (unless all defaults theretofore or thereupon shall have been remedied) at its option, by written
notice to the Company, declare this Note to be due and payable, whereupon the same shall forthwith mature and become due and payable
without presentment, demand, protest or other notice, all of which are hereby waived.


 


5.2            Remedies
on and Notices of Default. Subject to the provisions of Section 4, in case any one or more Events of Default
shall occur, the Holder may, with the consent of the holders of 67% of the then outstanding principal amount of the Notes, proceed
to protect and enforce the rights of such holder by a suit in equity, action at law or other appropriate proceeding, whether for
the specific performance of any agreement contained in this Note, or for an injunction against a violation of any of the terms
or provisions hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law. In case of a default
under this Note, the Company will pay to the Holder such further amount as shall be sufficient to cover the reasonable cost and
expense of enforcement, including, without limitation, reasonable attorneys’ fees. If the Holder shall give any notice or
take any other action in respect of a claimed default, the Company shall forthwith give written notice thereof to all other holders
of similarly subordinated notes at the time outstanding, describing the notice or action and the nature of the claimed default.
No course of dealing and no delay on the part of any Holder of this Note in exercising any right shall operate as a waiver thereof
or otherwise prejudice such Holder’s rights or the rights of the holder of any similarly subordinated notes. No remedy conferred
by this Note upon the Holder shall be exclusive of any other remedy referred to herein or now or hereafter available at law, in
equity, by statute or otherwise. In addition to the foregoing remedies, upon the occurrence or existence of any Event of Default,
the Holder may exercise any other right, power or remedy granted to the Holder as set forth in the Security Agreement.


 


6.            Conversion.


 


6.1            Automatic
Conversion. If at any time after one hundred eighty (180) days after the issuance of this Note the Closing Bid Price or
Closing Sales Price, as the case may be, of a share of the Company’s Common Stock equals or exceeds $4.50 (subject to appropriate
adjustment in the event of a stock split, stock dividend, combination or similar event) for twenty (20) consecutive Trading Days,
then the principal amount of this Note shall automatically convert into shares of Common Stock at the Conversion Price (as defined
below). Accrued and unpaid interest on the date of such automatic conversion shall be paid in cash by the Company. The conversion
will be deemed to have occurred as of the close of business on such twentieth (20th) consecutive Trading Day. The Company
shall notify the Holder in writing within one (1) Trading Day after any automatic conversion, and will cause certificate representing
the Conversion Shares to be issued within three (3) Trading Days after automatic conversion, and will deliver those certificates
to the Holder by overnight courier immediately after receipt of the original of this Note for cancellation.


 



    	-12-



    	 



    

6.2            Conversion
Procedure in the Event of Automatic Conversion. In the event of automatic conversion, the outstanding principal under this
Note will convert automatically without any further action by the Company whether or not the Note is surrendered to the Company
or its transfer agent. The Company will not be obligated to issue certificates evidencing the securities issuable upon automatic
conversion of this Note unless this Note is either delivered to the Company or its transfer agent, or the Holder notifies the Company
or its transfer agent that this Note has been mutilated, lost, stolen or destroyed and executes an agreement reasonably satisfactory
to the Company to indemnify the Company from any loss incurred by it in connection with this Note. At its expense, the Company
will, as soon as reasonably practicable thereafter, issue and deliver to the Holder a certificate for the number of shares of Common
Stock to which the Holder will be entitled upon conversion (bearing such legends as are required by applicable state and federal
securities laws in the opinion of counsel to the Company), together with a check payable to the Holder for any cash amounts payable
as described in Section 6.1 (with respect to accrued and unpaid interest) and Section 6.5 (with respect
to fractional shares).


 


6.3            Voluntary
Conversion. The Holder may, at any time before this Note has been repaid in full, elect to convert all or any portion of
the outstanding principal into shares of Common Stock at the Conversion Price.


 


6.4            Conversion
Procedure in the Event of Voluntary Conversion.


 


(a)            Each
voluntary conversion of this Note shall be effected by the surrender of this Note at the principal office of the Company at any
time during normal business hours, together with a written notice by the Holder stating that the Holder desires to convert the
entire, or a specified increment of, principal of this Note into Common Stock. Each conversion of a Note will be deemed to have
been effected as of the close of business on the date on which this Note has been surrendered and the notice has been received,
and at that time, the rights of the Holder of this Note will cease and the person or persons in whose name or names any certificate
or certificates for Common Stock are to be issued upon conversion will be deemed to have become the Holder or Holders of record
of the shares of Common Stock represented thereby.


 



    	-13-



    	 



    

(b)            Within
two (2) Trading Days after a conversion has been effected, the Company will deliver to the converting Holder:


 


(i)            a
certificate or certificates representing the number of shares of Common Stock issuable by reason of conversion in such name or
names and such denomination or denominations as the converting Holder has specified; and


 


(ii)          a
replacement Note representing the principal amount of this Note delivered to the Company in connection with the conversion but
which was not converted.


 


(c)            The
issuance of certificates for Common Stock upon conversion of this Note will be made without charge to the Holder for any tax in
respect thereof or other cost incurred by the Company in connection with conversion and the related issuance of Common Stock. Upon
conversion of any portion of this Note, the Company will take all actions as are necessary in order to ensure that the Common Stock
issuable with respect to conversion will be validly issued, fully paid and nonassessable.


 


(d)            The
Company will not close its books against the transfer of this Note or of the shares of Common Stock issued or issuable upon conversion
of this Note in any manner which interferes with the timely conversion of this Note, and will at all times reserve for issuance
the maximum number of shares of Common Stock into which this Note is convertible.


 


6.5            Fractional
Shares; Interest. No fractional shares shall be issued upon conversion of this Note. In lieu of the Company issuing any
fractional shares to Holder upon the conversion of this Note, the Company shall pay to Holder an amount in cash equal to the product
obtained by multiplying the Conversion Price applied to effect such conversion by the fraction of a share not issued pursuant to
the previous sentence. Upon conversion of this Note in full or the payment of outstanding amounts specified in this Note, the Company
shall be released from all its obligations and liabilities under this Note.


 


6.6            Conversion
Price. The initial Conversion Price shall be $0.40 per share of Common Stock. The Conversion Price shall be subject to
adjustment as described in Section 7.


 


7.            Conversion
Price Adjustments.


 


7.1            Adjustments
for Stock Splits and Subdivisions. In the event the Company should at any time or from time to time after the date of issuance
hereof fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination
of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock without
payment of any consideration by such holders for the additional shares of Common Stock, then, as of such record date (or the date
of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price shall be appropriately decreased
so that the number of shares of Common Stock issuable upon conversion of this Note shall be increased in proportion to such increase
of outstanding shares.


 



    	-14-



    	 



    

7.2            Adjustments
for Reverse Stock Splits. If the number of shares of Common Stock outstanding at any time after the date hereof is decreased
by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion
Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion hereof shall be decreased
in proportion to such decrease in outstanding shares.


 


7.3            Subsequent
Equity Sales. 


 


(a)            If,
at any time while this Note is outstanding, the Company sells or grants any option to purchase or sells or grants any right to
reprice, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any
Common Stock or Common Stock Equivalents entitling any Person to acquire shares of Common Stock at an effective price per share
that is lower than the then Conversion Price (such lower price, the “Base Conversion Price” and such issuances,
collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued
shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange
prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled
to receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall
be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price
shall be reduced to equal the Base Conversion Price. Such adjustments shall be made whenever such Common Stock or Common Stock
Equivalents are issued.


 


(b)            Notwithstanding
the foregoing, no adjustment will be made under this Section 7.3 in respect of an Exempt Issuance. The Company shall
notify the Holder in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalents
subject to this Section 7.3, indicating therein the applicable issuance price, or applicable reset price, exchange
price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes
of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 7.3, upon
the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Conversion Shares based upon the Base Conversion
Price on or after the date of such Dilutive Issuance.


 


(c)            Calculations.
All calculations under this Section 7 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 7, 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 treasury shares, if any) issued and outstanding.


 



    	-15-



    	 



    

7.4            Notices
of Record Date, Etc. In the event of:


 


(a)            Any
taking by the Company of a record of the holders of any class of securities of the Company for the purpose of determining the holders
thereof who are entitled to receive any dividend (other than a cash dividend payable out of earned surplus at the same rate as
that of the last such cash dividend theretofore paid) or other distribution or any right to subscribe for, purchase or otherwise
acquire any shares of stock of any class or any other securities or property, or to receive any other right; or


 


(b)            Any
capital reorganization of Company, any reclassification or recapitalization of the capital stock of Company or any transfer of
all or substantially all of the assets of the Company to any other Person or any consolidation or merger involving the Company;
or


 


(c)            Any
voluntary or involuntary dissolution, liquidation or winding-up of the Company,


 


the Company will mail to the
Holder at least ten (10) days prior to the earliest date specified therein, a notice specifying (A) the date on which any such
record is to be taken for the purpose of such dividend, distribution or right and the amount and character of such dividend, distribution
or right; and (B) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation
or winding-up is expected to become effective and the record date for determining shareholders entitled to vote thereon.


 


7.5            Reservation
of Stock Issuable Upon Conversion. The Company shall at all times reserve and keep available out of its authorized but
unissued shares of Common Stock for the purpose of effecting the conversion of this Note such number of its shares of Common Stock
as shall from time to time be sufficient to effect the conversion of this Note; and if at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the conversion of the entire outstanding principal amount of
this Note, without limitation of such other remedies as shall be available to the Holder of this Note, the Company will use its
best efforts to take such corporate action as may, in the opinion of counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such purposes.


 


8.            Successors
and Assigns. Subject to the restrictions on transfer described in Sections 10 and 11, the rights and obligations
of Company and the Holder shall be binding upon and benefit the successors, assigns, heirs, administrators and transferees of the
parties.


 


9.            Waiver
and Amendment. Any provision of this Note may be amended, waived or modified upon the written consent of Company and the
holders of a majority in principal amount of the Notes.


 



    	-16-



    	 



    

10.            Transfer
of this Note or Securities Issuable on Conversion Hereof. With respect to any offer, sale or other disposition of this
Note or securities into which such Note may be converted, the Holder will give written notice to the Company prior thereto, describing
briefly the manner thereof, together with a written opinion of the Holder’s counsel, or other evidence if reasonably satisfactory
to the Company, to the effect that such offer, sale or other distribution may be effected without registration or qualification
(under any federal or state law then in effect). Upon receiving such written notice and reasonably satisfactory opinion, if so
requested, or other evidence, the Company, as promptly as practicable, shall notify the Holder that the Holder may sell or otherwise
dispose of this Note or such securities, all in accordance with the terms of the notice delivered to Company. If a determination
has been made pursuant to this Section 10 that the opinion of counsel for the Holder, or other evidence, is not reasonably
satisfactory to the Company, the Company shall so notify the Holder promptly after such determination has been made. Each Note
thus transferred and each certificate representing the securities thus transferred shall bear a legend as to the applicable restrictions
on transferability in order to ensure compliance with the Securities Act, unless in the opinion of counsel for the Company such
legend is not required in order to ensure compliance with the Securities Act. The Company may issue stop transfer instructions
to its transfer agent in connection with such restrictions. Subject to the foregoing transfers of this Note shall be registered
upon registration books maintained for such purpose by or on behalf of the Company as provided in the Securities Purchase Agreement.
Prior to presentation of this Note for registration of transfer, the Company shall treat the registered Holder hereof as the owner
and the Holder of this Note for the purpose of receiving all payments of principal and interest hereon and for all other purposes
whatsoever, whether or not this Note shall be overdue and the Company shall not be affected by notice to the contrary.


 


11.            Assignment
by the Company. Neither this Note nor any of the rights, interests or obligations hereunder may be assigned, by operation
of law or otherwise, in whole or in part, by Company without the prior written consent of the Holder.


 


12.            Notices.
All notices, requests, demands, consents, instructions or other communications required or permitted hereunder shall in writing

Agreement, or at such other address or facsimile number as the Company shall have furnished to Holder in writing. All such notices
and communications shall be effective (i) when sent by Federal Express or other overnight service of recognized standing, on the
Business Day following the deposit with such service; (ii) when mailed, by registered or certified mail, first class postage prepaid
and addressed as aforesaid through the United States Postal Service, upon receipt; (iii) when delivered by hand, upon delivery;
and (iv) when faxed, upon confirmation of receipt.


 


13.            Secured
Obligation. The obligations of the Company under this Note are secured by all assets of the Company and pursuant to the
Security Agreement between the Company and the Secured Parties (as defined therein).


 


14.            Pari
Passu Notes. This Note ranks pari passu with all other Notes now or hereafter issued in connection with the
Memorandum. The Holder acknowledges and agrees that the payment of all or any portion of the outstanding principal amount of this
Note and all interest hereon shall be pari passu in right of payment and in all other respects to the other Notes.
In the event the Holder receives payments in excess of its pro rata share of the Company’s payments to the holders of all
of the Notes, then the Holder shall hold in trust all such excess payments for the benefit of the holders of the other Notes and
shall pay such amounts held in trust to such other holders upon demand by such holders.

Payment shall be made in lawful tender of the United States.


 


16.            Usury.
In the event any interest is paid on this Note which is deemed to be in excess of the then legal maximum rate, then that portion
of the interest payment representing an amount in excess of the then legal maximum rate shall be deemed a payment of principal
and applied against the principal of this Note.


 


17.            Waivers.
The Company hereby waives notice of default, presentment or demand for payment, protest or notice of nonpayment or dishonor and
all other notices or demands relative to this instrument.
