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”)

of:


 


(i)             
the existence of a Payment Default; or

the existence of any event of default (other than a Payment Default) under any agreement or instrument pursuant to which
any Senior Indebtedness is issued, in each instance as now in effect or as hereafter from time to time modified or amended, without
the necessity of any consent by or notice to the Holders (a “Specified Covenant Default”);


 


until the earlier of (i) the date
such Payment Default or Specified Covenant Default is cured, waived in writing or otherwise ceases to exist and (ii) the one hundred
eightieth (180th) day after receipt by the Company and/or by the holder of this Note of such Deferral Notice; provided,

date such subsequent Deferral Notice is received by the Company and the holders of Subordinated Notes and (2) the three hundred

(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.

4.9           
Not 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

of this Note.


 


5.              
Default.


 


5.1           
Events of Default. If any of the following events (each, an “Event of Default” and collectively,
“Events of Default”) shall occur:


 


(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
case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator,
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
of sixty (60) consecutive days; or


 



    	-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 and faxed, mailed or delivered to each party at the respective addresses of the parties as set forth
in the Securities Purchase 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 Exchange Agreements. 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.

15.           
Payment. 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.


 


18.           
Governing Law. This Note and all actions arising out of or in connection with this Note shall be governed
by and construed in accordance with the laws of the State of California, without regard to the conflicts of law provisions of the
