““Daily VWAP”

volume-weighted average price is unavailable, the market value of one share of Common Stock on such Trading Day determined, using a volume-weighted
average method, by a nationally recognized independent investment banking firm retained for this purpose by the Issuer). The “Daily
VWAP” will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading
hours.”

4.3 Section
1 of each Convertible Note is amended by inserting a definition of “First Amendment Effective Date” in appropriate alphabetical

““Redemption
Price” the sum of (i) the principal amount then outstanding, (ii) any accrued and unpaid interest through the applicable redemption
date, and (iii) the outstanding principal amount of the Convertible Note multiplied by the applicable percentage set forth in the below
table (such applicable amount, the “Make-Whole Amount”):

 

	 	Stock Price
	Effective Date	$6.40	$7.68	$8.96	$10.24	$11.52	$12.80	$16.00	$19.20	$25.60	$32.00	 
	December 31, 2021	15.0%	11.9%	9.8%	8.2%	7.0%	6.1%	4.4%	3.3%	1.9%	0%

	December 31, 2023	15.0%	9.7%	7.8%	6.6%	0%	0%	0%	0%	0%	0%	 
	December 31, 2024	15.0%	7.9%	6.2%	0%	0%	0%	0%	0%	0%	0%	 

 

For purposes of the table set forth immediately
above and for the purposes of making any Make-Whole Amount determination, “Stock Price” means (A) in the case of an
Optional Redemption, the Last Reported Sale Price; (B) in the case of a Fundamental Change, the price paid per share of Common Stock in
the transaction constituting the Fundamental Change, if holders of Common Stock receive only cash in the transaction constituting the
Fundamental Change, the Stock Price shall equal the cash amount paid per share of Common Stock; (C) in the case that (x) there has been
a Termination of Trading or (y) if on the date of such Prepayment Event, the Stock Price per share of Common Stock is less than Six Dollars
and Forty Cents ($6.40), then the Stock Price for the purposes of determining the applicable Make-Whole Amount based on the table above,
the Stock Price shall be deemed to be equal to Six Dollars and Forty Cents ($6.40) as of the applicable date; or (D) in all other cases
other the those described in clauses (A), (B) and (C) above, the Stock Price shall equal the arithmetic average of the Last Reported Sale
Price over the five Trading Day period ending on the Trading Day immediately preceding the Effective Date of the Fundamental Change or,
as the context may require, such other Prepayment Event. It being further provided that if as of the date of such Prepayment Event, the
Stock Price is greater than Thirty Two Dollars ($32.00), then the Stock Price for the purposes of determining the applicable Make-Whole
Amount shall be deemed to be Thirty Two Dollars ($32.00) as of the applicable date.

 

The exact Stock Price and Effective Date may not
be set forth in the table above, in which case if the Stock Price is between two Stock Prices in the table above or the Effective Date
is between two dates in the table, the applicable percentage shall be determined by a straight-line interpolation between applicable percentage
set forth for the higher and lower Stock Prices and the earlier and later dates, as applicable, based on a 365-day or 366-day year, as
applicable.

 

    5

     

    

 

The Stock Prices set forth in the column headings
of the table above shall be adjusted as of any date on which the Conversion Price is otherwise adjusted. The adjusted Stock Price shall
equal the Stock Price immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately
prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted.”

 

4.6 Section
1 of each Convertible Note is amended by inserting a definition of “Threshold Price” in appropriate alphabetical order to
read as follows:

 

“Threshold Price”
means $10.00. The Threshold Price is subject to adjustment in the same manner and at the same time as the Conversion Price is adjusted
from time to time as set forth in this Convertible Note, except that no adjustment will be made to the Threshold Price in connection with
an adjustment of the Conversion Price pursuant to Section 4.5(f) or Section 4.5(g).”

 

4.7 The
reference to “Conversion Price” in the definition of “Triggering Event” in each Convertible Note shall be replaced
entirely with a reference to “Triggering Price”.

 

4.8 Section
1 of each Convertible Note is amended by inserting a definition of “Triggering Price” in appropriate alphabetical order to
read as follows:

 

““Triggering
Price” means $12.50. The Triggering Price is subject to adjustment in the same manner and at the same time as the Conversion
Price is adjusted from time to time as set forth in this Convertible Note, except that no adjustment will be made to the Triggering Price
in connection with an adjustment of the Conversion Price pursuant to Section 4.5(g).”.

 

4.9 The
following shall be inserted as Section 4.5(g) to each Convertible Note:

 

“(g) Adjustment
Relating to Trading Price. If, during the period commencing on and including the First Amendment Effective Date and ending on and
including the fifteen (15) month anniversary of the First Amendment Effective Date, there is no thirty (30) consecutive Trading Day-period
during which the average of the Daily VWAPs for such thirty (30) consecutive Trading Day period (after excluding the three (3) highest
and the three (3) lowest Daily VWAPs during such period) equals or exceeds the Threshold Price, the Conversion Price shall be reduced
to an amount equal to the amount that the Conversion Price would otherwise have been had the Conversion Price been $6.00 on the First
Amendment Effective Date (with corresponding adjustments to other terms of this Convertible Note that are based on the Conversion Price,
including, without limitation, the table set forth in the definition of “Redemption Price”).”

 

4.10 The
following shall be inserted as Section 16 to each Convertible Note:

 

“16. Amendment and
Restatement.

 

THIS CONVERTIBLE NOTE IS ISSUED

be the last quoted bid price per share for the Common Stock in the over-the-counter market on the relevant date as reported by OTC Markets
Group Inc. or a similar organization. If the Common Stock is not so quoted, the “Last Reported Sale Price” shall be
the average of the mid-point of the last bid and ask prices per share for the Common Stock on the relevant date from each of at least
three nationally recognized independent investment banking firms selected by the Issuer for this purpose at its expense. The “Last
Reported Sale Price” shall be determined by the Issuer, except to the extent otherwise specified in this definition.

 

    4

     

    

 

“Net Cash Proceeds”
means:

 

(a) with respect
to any Transfer (other than the issuance of Equity Interests of Issuer, which is addressed under clause (b) of this definition), Asset
Disposition or any insurance or condemnation award, the aggregate cash proceeds (including cash proceeds received pursuant to policies
of insurance or condemnation awards or by way of deferred payment of principal pursuant to a note, installment receivable or otherwise,
but only as and when cash is actually received) received by Issuer or any Subsidiary pursuant to any such Transfer, Asset Disposition
or insurance proceeds or condemnation award net of (i) the direct costs relating to such Asset Disposition (including sales commissions
and legal, accounting and investment banking fees), (ii) net income taxes paid as a result thereof (after taking into account any tax
credits or deductions and any tax sharing arrangements) and (iii) amounts required to be applied to the repayment of any Indebtedness
secured by a Lien on the asset subject to any such Transfer or other Asset Disposition (other than a Convertible Note) or required to
be paid to parties (other than Affiliates of a Note Party) having superior rights to the proceeds of any such Transfer or other Asset
Disposition to the extent such superior rights are permitted hereunder; and

 

(b) with respect
to any issuance of Equity Interests of Issuer or Indebtedness of the Issuer or its Subsidiaries (excluding Permitted Indebtedness), the
aggregate cash proceeds received by Issuer or any of its Subsidiaries pursuant to such issuance, net of the direct costs of such issuance
(including reasonable and documented up-front, underwriters’ and placement fees and any related tax, legal and accounting fees)
to the extent that such costs, fees and expenses are paid to non-Affiliates (including the payment of the Pacific Western Success Fee).

 

“Original Issuance
Date” means August 13, 2021.

 

“Redemption Price”
the sum of (i) the principal amount then outstanding, (ii) any accrued and unpaid interest through the applicable redemption date, and
(iii) the outstanding principal amount of the Convertible Note multiplied by the applicable percentage set forth in the below table (such
applicable amount, the “Make-Whole Amount”):

 

	 	Stock
    Price
	Effective Date	$6.40	$7.68	$8.96	$10.24	$11.52	$12.80	$16.00	$19.20	$25.60	$32.00	 
	December 31, 2021	15.0%	11.9%	9.8%	8.2%	7.0%	6.1%	4.4%	3.3%	1.9%	0%	 
	December 31, 2022	15.0%	11.0%	9.0%	7.6%	6.5%	5.6%	4.1%	3.1%	0%	0%	 
	December 31, 2023	15.0%	9.7%	7.8%	6.6%	0%	0%	0%	0%	0%	0%	 
	December 31, 2024	15.0%	7.9%	6.2%	0%	0%	0%	0%	0%	0%	0%	 

 

For purposes of the table set forth immediately
above and for the purposes of making any Make-Whole Amount determination, “Stock Price” means (A) in the case of an Optional
Redemption, the Last Reported Sale Price; (B) in the case of a Fundamental Change, the price paid per share of Common Stock in the transaction
constituting the Fundamental Change, if holders of Common Stock receive only cash in the transaction constituting the Fundamental Change,
the Stock Price shall equal the cash amount paid per share of Common Stock; (C) in the case that (x) there has been a Termination of Trading
or (y) if on the date of such Prepayment Event, the Stock Price per share of Common Stock is less than Six Dollars and Forty Cents ($6.40),
then the Stock Price for the purposes of determining the applicable Make-Whole Amount based on the table above, the Stock Price shall
be deemed to be equal to Six Dollars and Forty Cents ($6.40) as of the applicable date; or (D) in all other cases other the those described
in clauses (A), (B) and (C) above, the Stock Price shall equal the arithmetic average of the Last Reported Sale Price over the five Trading
Day period ending on the Trading Day immediately preceding the Effective Date of the Fundamental Change or, as the context may require,
such other Prepayment Event. It being further provided that if as of the date of such Prepayment Event, the Stock Price is greater than
Thirty Two Dollars ($32.00), then the Stock Price for the purposes of determining the applicable Make-Whole Amount shall be deemed to
be Thirty Two Dollars ($32.00) as of the applicable date.

 

    5

     

    

 

The exact Stock Price and Effective Date may not
be set forth in the table above, in which case if the Stock Price is between two Stock Prices in the table above or the Effective Date
is between two dates in the table, the applicable percentage shall be determined by a straight-line interpolation between applicable percentage
set forth for the higher and lower Stock Prices and the earlier and later dates, as applicable, based on a 365-day or 366-day year, as
applicable.

 

The Stock Prices set forth in the column headings
of the table above shall be adjusted as of any date on which the Conversion Price is otherwise adjusted. The adjusted Stock Price shall
equal the Stock Price immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately
prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted.

 

“Termination of Trading”
shall be deemed to have occurred if the Common Stock or other common stock or American Depositary Shares or similar instruments into which
the Convertible Note is convertible is not listed for trading on the New York Stock Exchange, the NYSE American, the Nasdaq Global Market,
the Nasdaq Global Select Market or the Nasdaq Capital Market (or any of their respective successors) or ceases to be traded in contemplation
of a delisting or withdrawal of approval.

 

“Threshold Price”
means $10.00. The Threshold Price is subject to adjustment in the same manner and at the same time as the Conversion Price is adjusted
from time to time as set forth in this Convertible Note, except that no adjustment will be made to the Threshold Price in connection with
an adjustment of the Conversion Price pursuant to Section 4.5(f) or Section 4.5(g).

 

“Trading Day”
means any day on which (i) trading in the Common Stock (or other security for which a closing sale price must be determined) generally
occurs (w) on the NYSE American, (x) if the Common Stock (or such other security) is not then listed on the NYSE American, on the principal
U.S. national securities exchange on which the Common Stock (or such other security) is then listed, (y) if the Common Stock (or such
other security) is not so listed, on the principal U.S. regional securities exchange on which the Common Stock (or such other security)
is then listed, or (z) if the Common Stock (or such other security) is not so listed, on the principal other market on which the Common
Stock (or such other security) are then traded. If the Common Stock is not so listed or admitted for trading, “Trading Day”
means a Business Day.

 

“Triggering Event”
means the occurrence, at any time after the second anniversary of the Original Issuance Date, of the Last Reported Sale Price of the Common
Stock for any thirty (30) consecutive Trading Days exceeding 130% of the Triggering Price then in effect and as adjusted pursuant to the
terms herein.

 

“Triggering Price”
means $12.50. The Triggering Price is subject to adjustment in the same manner and at the same time as the Conversion Price is adjusted
from time to time as set forth in this Convertible Note, except that no adjustment will be made to the Triggering Price in connection
with an adjustment of the Conversion Price pursuant to Section 4.5(g).

 

2. Payments.

 

(a) The outstanding
principal balance and other Obligations evidenced by this Convertible Note and the other Note Documents shall bear interest on and after
the Original Issuance Date, at the then Applicable Rate. Interest shall be computed on the basis of a 360-day year of twelve (12) thirty
(30) day months and shall accrue commencing on the Original Issuance Date. For the avoidance of doubt, any interest due and payable in
respect of the Obligations shall include any interest calculated using the Default Rate to the extent applicable.

 

    6

     

    

 

Notwithstanding anything to
the contrary contained herein or in any other Note Document, the interest paid or agreed to be paid under the Note Documents shall not
exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Holder receives
interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal amount of the Obligations or,
if it exceeds such unpaid principal, refunded to the Issuer. In determining whether the interest contracted for, charged, or received
by the Holder exceeds the Maximum Rate, the Holder may, to the extent permitted by applicable Law, (a) characterize any payment that is
not principal as an expense, fee, Make-Whole Amount or premium rather than interest; (b) exclude voluntary prepayments and the effects
thereof; and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated
term of the Obligations.

 

(b) Accrued interest,
if any, on the principal amount of this Convertible Note shall be payable quarterly in arrears on each Interest Payment Date, with the
first such payment to be made on September 30, 2021 (the “Initial Interest Payment Date”). Subject to the provisions
of Section 4 hereof relating to the conversion of this Convertible Note, the entire principal sum hereof, together with any accrued
and unpaid interest thereon (including post-petition interest in any proceeding under any Debtor
Relief Law) and other Obligations (other than yet unasserted contingent obligations), shall be due and payable on the Maturity
Date. Additionally, accrued and unpaid interest (including post-petition interest in any proceeding
under any Debtor Relief Law) on the Obligations shall be due and payable upon any of the following: (i) the payment of the entire
principal sum hereof; or (ii) conversion of this Convertible Note pursuant to the provisions of Section 4 hereof as to that portion
of the principal amount so converted. Interest will be paid to the person in whose name a Convertible Note is registered at the Close
of Business on the fifth (5th) calendar day prior to the relevant Interest Payment Date, whether or not a Business Day (the
“Regular Record Date”). 

 

(c) The principal
amount and any accrued and unpaid interest of this Convertible Note shall be paid by wire transfer in immediately available funds in United
States dollars at the account and/or wire directions provided by the Holder. If any day on which any amount is payable under this Convertible
Note is not a Business Day, then the amount otherwise payable on that date will be made on the next succeeding day that is a Business
Day (without any interest or other payment in respect of such delay) (each such day on which principal or interest is payable pursuant
hereto, a “Payment Date”).

 

(d) Except as otherwise
expressly provided herein, all holders of Convertible Notes must be treated equally with respect to such payment of interest amounts.
Subject to the terms of the Intercreditor Agreement, in the event of any partial payment of principal or accrued interest, for whatever
reason, any such partial payment of principal and/or interest on the Convertible Notes shall be allocated among the respective Convertible
Notes and holders thereof so that the amount of such payments to each holder shall bear as nearly as practicable the same ratio to the
aggregate amount then to be paid as the principal amount of the Convertible Notes then held by such holder bears to the aggregate principal
amount of Convertible Notes then outstanding.

 

3. Seniority; Security Interest

 

(a) The indebtedness
evidenced by this Convertible Note and the payment of the Obligations evidenced hereby and by the other Note Documents shall rank pari
passu with the other Priority Lien Obligations and shall rank senior to, and have priority in right of payment over, all other indebtedness
of Issuer and its Subsidiaries now or hereafter outstanding.

 

(b) This Convertible
Note, along with the other Note Documents, is secured by a Lien on and security interest in certain assets of the Issuer and certain of
its Subsidiaries, as described in the Collateral Documents and such security interest and guarantee shall be secured on a pari passu
basis by the same persons and collateral and assets as the Liens securing the other Priority Lien Obligations. By its acceptance of this
Convertible Note, the Holder has authorized the Collateral Agent to act on behalf of the Holder and other holders of the Convertible Notes,
and in such capacity to enter into the Collateral Documents and the Intercreditor Agreement and certain other Note Documents, as the same
may be amended, modified, restated or supplemented from time to time, and to exercise for the benefit of the Holder all rights, powers
and remedies provided to the Collateral Agent, under or pursuant to the Collateral Documents, the Intercreditor Agreement and the other
Note Documents including, without limitation, those available upon an Event of Default.

4. Conversion

 

4.1. Conversion
Rights. The unpaid principal amount of this Convertible Note (together with all accrued
but unpaid interest thereon) shall be convertible, in whole or in part, at the option of the Holder at any time prior to the payment
in full of the principal amount of this Convertible Note (together with all accrued but unpaid interest thereon), into such number of
shares of fully paid and non-assessable shares of Common Stock as is determined by dividing the principal amount of the Convertible Note
so converted (together with all accrued but unpaid interest thereon) by the Conversion Price (the “Holder Conversion Right”).
The Issuer shall pay any and all transfer agent fees, legal fees, costs and any other fees or costs that may be incurred or charged in
connection with the issuance of shares of Common Stock to the Holder arising out of or relating to the conversion of this Convertible
Note.

 

4.2. Issuance
of Certificates. The Holder Conversion Right may be exercised by the Holder by the surrender
of this Convertible Note (or of any replacement Convertible Note issued hereunder) with the conversion notice attached hereto as Exhibit
A duly executed, at the principal office of the Issuer or the transfer agent of the Issuer. Conversion shall be deemed to have been
effected on the date that such delivery of the Convertible Note and conversion notice is actually made (the “Conversion Date”).
As promptly as practicable, and in any event within three (3) Trading Days, after a Conversion Date and the Issuer’s receipt of
the Convertible Note being converted (and the conversion notice, if applicable) (such third Trading Day thereafter, the “Share
Delivery Date”), the Issuer shall (A) if legends are not required to be placed on certificates of Common Stock pursuant to
the then existing provisions of Rule 144 of the Securities Act of 1933 (“Rule 144”) and provided that the transfer
agent is participating in The Depository Trust Company's (“DTC”) Fast Automated Securities Transfer Program, credit
such aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holder's or its designee's balance account
with DTC through its Deposit/Withdrawal at Custodian system or (B) if legends are required to be placed on certificates of Common Stock
pursuant to Rule 144 or the transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver
to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number
of shares of Common Stock to which the Holder shall be entitled, which certificates shall not bear any restrictive legends unless required
pursuant to Rule 144 and a check or cash with respect to any fractional interest in a share of Common Stock as provided in Section
4.4. The Issuer shall not be obligated to credit Common Stock or issue Common Stock certificates in the name of any party other than
the Holder of the Convertible Notes, absent full compliance with the provisions of Section 9 hereof. The person in whose name
the certificate or certificates for Common Stock are to be issued or credited shall be deemed to have become a stockholder of record
on the next succeeding day on which the transfer books are open, but the Conversion Price shall be that in effect on the Conversion Date.
All rights with respect to the Convertible Notes (or any portion thereof) that are converted pursuant to this Section 4, including
the rights to receive interest and notices, shall terminate upon the conversion pursuant to this Section 4.2. Upon conversion
of only a portion of this Convertible Note, the Issuer shall issue and deliver to the Holder hereof, at the expense of the Issuer, a
new Convertible Note covering the principal amount of this Convertible Note not converted, which new Convertible Note shall entitle the
holder thereof to interest on the principal amount thereof to the same extent as if the unconverted portion of this Convertible Note
had not been surrendered for conversion.

 

4.3. Reservation
of Common Stock Issuable Upon Conversion. The Issuer covenants that, for so long as any
Convertible Notes remain outstanding, the Issuer will at all times have authorized and reserved for the purpose of issuance upon exercise
of the Holder Conversion Right, a sufficient number of duly authorized shares of Common Stock to provide for the full exercise of the
Holder Conversion Right. If at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding Convertible Notes, the Issuer shall take such corporate action as may be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without
limitation, obtaining the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation.

 

    8

     

    

 

4.4. Fractional
Shares. No fractional shares of Common Stock shall be issued upon conversion of this Convertible
Note. In lieu of any fractional shares to which the Holder would otherwise be entitled, the Issuer shall pay cash equal to the product
of such fraction multiplied by the Last Reported Sale Price on the Conversion Date, as determined in good faith by the Board.

 

4.5. Adjustment
of Conversion Price. The Conversion Price and the number and kind of securities, including
the Common Stock, which may be received upon the exercise of the Holder Conversion Right shall be subject to the adjustment from time
to time upon the happening of certain events, as follows:

 

(a) Adjustment
for Stock Splits and Combinations. If the Issuer shall at any time or from time to time after the Original Issuance Date effect a
stock split or subdivision of the outstanding Common Stock, the Conversion Price then in effect immediately before that stock split or
subdivision shall be proportionately decreased, and conversely, if the Issuer shall at any time or from time to time after the Original
Issuance Date combine the outstanding shares of Common Stock, the Conversion Price then in effect immediately before the combination shall
be proportionately increased. Any adjustment under this Section 4.5(a) shall become effective at the Close of Business on the date
the stock split or subdivision or combination becomes effective.

 

(b) Adjustment
for Certain Dividends and Distributions. In the event the Issuer shall at any time or from time to time after the Original Issuance
Date make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution
payable on the Common Stock in additional shares of Common Stock, then and in each such event the Conversion Price then in effect immediately
before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of
the Close of Business on such record date, by multiplying the Conversion Price then in effect by a fraction:

 

(i) the numerator
of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or
the Close of Business on such record date; and

 

(ii) the denominator
of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or
the Close of Business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution;
provided, however, if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not
fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the Close of Business on such record
date and thereafter such Conversion Price shall be adjusted pursuant to this Section 4.5(b) as of the time of actual payment of
such dividends or distributions.

 

(c) Adjustments
for Other Dividends and Distributions. In the event the Issuer at any time or from time to time after the Original Issuance Date shall
make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution
payable in securities of the Issuer other than shares of Common Stock or in other property, then and in each such event an appropriate
revision to the applicable Conversion Price shall be made and provisions shall be made (by adjustments of the Conversion Price or otherwise)
so that the Holders shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, a
dividend or other distribution of such securities or other property in an amount equal to the amount of such securities or other properties
of the Issuer which they would have received had their Convertible Notes been converted into Common Stock on the date of such event and
had thereafter, during the period from the date of such event to and including the Conversion Date, retained such securities (together
with any distributions payable thereon during such period) receivable by them as aforesaid during such period, giving application to all
adjustments called for during such period under this Section 4.5 with respect to the rights of the Holders.

 

    9

     

    

 

(d) Adjustment
for Reclassification, Exchange or Substitution. If the Common Stock issuable upon the conversion of the Convertible Notes at any time
or from time to time after the Original Issuance Date shall be changed into the same or different number of shares of any class or classes
of stock, whether by capital reorganization, reclassification, exchange, substitution or otherwise (other than a stock split, subdivision
or combination of shares provided for in Section 4.5(a) above, stock or other dividend or distribution provided for in Section
4.5(b) or (c) above, or a Business Combination or sale of assets provided for in Section 4.5(e) below), then and in
each such event an appropriate revision to the applicable Conversion Price shall be made and provisions shall be made (by adjustments
of the Conversion Price or otherwise) so that the Holder shall have the right thereafter to convert each Convertible Note into the kind
and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification, exchange, substitution
or other change, as holders of the number of shares of Common Stock into which such Convertible Note might have been converted immediately
prior to such reorganization, reclassification, exchange, substitution or other change, all subject to further adjustment as provided
herein.

 

(e) Reorganization,
Merger, Consolidation or Sale of Assets. If at any time or from time to time there shall be a capital reorganization of the Common
Stock (other than a stock split, subdivision or combination of shares provided for in Section 4.5(a) above, stock or other dividend
or distribution provided for in Section 4.5(b) or (c) above, or a reclassification, exchange or substitution provided for
in Section 4.5(d) above) or a Business Combination of the Issuer with or into another corporation or entity, or the sale of all
or substantially all of the Issuer’s properties and assets to any other person, then, as a part of such Business Combination provision
shall be made so that the Holders of the Convertible Notes shall thereafter be entitled to receive upon conversion of the Convertible
Notes, the number of shares of stock or other securities, Equity Interests or property of the Issuer, or of the successor entity resulting
from such Business Combination, to which a Holder of Common Stock (or any shares of stock or other
securities or Equity Interests which may be) issuable upon conversion of the Convertible Note would have been entitled if the Convertible
Note had been converted immediately prior to such Business Combination. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4.5 with respect to the rights and interests of the Holders after the Business Combination
to the end that the provisions of this Section 4.5 (including adjustment of the Conversion Price then in effect and the number
of Common Stock or other securities receivable upon conversion of the Convertible Notes) shall be applicable after that event.

 

(f) Adjustments
for Dilutive Issuances.

 

(i) Special Definitions.
For purposes of this Section 4.5(f), the following definitions shall apply:

 

(A) “Additional Shares
of Common Stock” shall mean all shares of Common Stock issued (or, pursuant to Section 4.5(f)(ii), deemed to be issued)
by the Issuer after the Original Issuance Date, other than (1) the following shares of Common Stock and (2) shares of Common Stock deemed
issued pursuant to the following Options and Convertible Securities (clauses (1) and (2), collectively, “Exempted Securities”):

 

(I) securities issued pursuant
to the conversion or exercise of Options or Convertible Securities issued or outstanding on or prior to the Original Issuance Date (so
long as the conversion or exercise price in such securities are not amended to lower such price and/or adversely affect the Holder);

 

(II) the Other Convertible
Notes and any additional debentures or other securities issued as payment of interest on the Convertible Notes;

 

(III) shares of Common Stock,
Options or Convertible Securities issued by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock
that is covered by Section 4.5(a) through Section 4.5(e);

 

    10

     

    

 

(IV) shares of Common Stock
or Options issued to employees or directors of, or consultants or advisors to, the Issuer or any of its subsidiaries pursuant to a plan,
agreement or arrangement approved by the Board;

 

(V) shares of Common Stock
or Convertible Securities actually issued upon the exercise of Options or shares of Common Stock actually issued upon the conversion or
exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such Option or Convertible Security;

 

(VI) shares of Common Stock,
Options or Convertible Securities issued pursuant to the acquisition of another corporation or other entity by the Issuer or any of its
subsidiaries by merger, purchase of all or substantially all of the assets or other reorganization or to a joint venture agreement, contribution
agreement or similar arrangement, provided that such issuances are approved by the Board and the Issuer owns, directly or indirectly,
not less than 51% of the voting stock of such other entity; or

 

(VII) shares of Common Stock,
Options or Convertible Securities issued pursuant to the terms of that certain Business Combination Agreement, dated as of March 8, 2021,
by and among the Issuer, Artemis Merger Sub Corp. and Airspan Networks Inc.

 

(B) “Convertible Securities”
shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common
Stock, but excluding Options.

 

(C) “Option”
shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities.

 

(ii) Deemed Issue
of Additional Shares of Common Stock.

 

(A) If the Issuer at any time
or from time to time after the Original Issuance Date shall issue any Options or Convertible Securities (excluding Options or Convertible
Securities which are themselves Exempted Securities) or shall fix a record date for the determination of holders of any class of securities
entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the
instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without
regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in
the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to
be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the
Close of Business on such record date.

 

(B) If the terms of any Option
or Convertible Security, the issuance of which resulted in an adjustment to the Conversion Price pursuant to the terms of Section 4.5(f)(iii),
are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible
Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible
Security) to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion
and/or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Issuer
upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Conversion Price
computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto)
shall be readjusted to such Conversion Price as would have obtained had such revised terms been in effect upon the original date of issuance
of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this Section 4.5(f)(ii)(B) shall
have the effect of increasing the Conversion Price to an amount which exceeds the lower of (i) the Conversion Price in effect immediately
prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, or (ii) the Conversion Price
that would have resulted from any issuances of Additional Shares of Common Stock (other than deemed issuances of Additional Shares of
Common Stock as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment
date.

 

    11

     

    

 

(C) If the terms of any Option
or Convertible Security (excluding Options or Convertible Securities which are themselves Exempted Securities), the issuance of which
did not result in an adjustment to the Conversion Price pursuant to the terms of Section 4.5(f)(iii) (either because the consideration
per share (determined pursuant to Section 4.5(f)(iv)) of the Additional Shares of Common Stock subject thereto was equal to or
greater than the Conversion Price then in effect, or because such Option or Convertible Security was issued before the Original Issuance
Date), are revised after the Original Issuance Date as a result of an amendment to such terms or any other adjustment pursuant to the
provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar
provisions of such Option or Convertible Security)  to provide for either (1) any increase in the number of shares of Common
Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any decrease in the consideration
payable to the Issuer upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted,
and the Additional Shares of Common Stock subject thereto (determined in the manner provided in Section 4.5(f)(ii)(A)) shall be
deemed to have been issued effective upon such increase or decrease becoming effective.

 

(D) Upon the expiration or termination
of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original
issuance or upon a revision of its terms) in an adjustment to the Conversion Price pursuant to the terms of Section 4.5(f)(iii),
the Conversion Price shall be readjusted to such Conversion Price as would have obtained had such Option or Convertible Security (or portion
thereof) never been issued.

 

(E) If the number of shares
of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable
to the Issuer upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued
or amended but is subject to adjustment based upon subsequent events, any adjustment to the Conversion Price provided for in this Section
4.5(f)(ii) shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without
regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (B) and (C)
of this Section 4.5(f)(ii)).  If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange
of any Option or Convertible Security, or the consideration payable to the Issuer upon such exercise, conversion and/or exchange, cannot
be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Conversion Price that
would result under the terms of this Section 4.5(f)(ii) at the time of such issuance or amendment shall instead be effected at
the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming
for purposes of calculating such adjustment to the Conversion Price that such issuance or amendment took place at the time such calculation
can first be made.

 

(iii) Adjustment
of Conversion Price Upon Issuance of Additional Shares of Common Stock.  In the event the Issuer shall, at any time after
the Original Issuance Date and for so long as this Convertible Note remains outstanding, issue Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to Section 4.5(f)(ii)), without consideration or for a consideration
per share less than the applicable Conversion Price in effect immediately prior to such issue, then the Conversion Price shall be reduced,
concurrently with such issue, to an amount (calculated to the nearest one-hundredth of a cent) determined in accordance with the following
formula:

 

CP2 = CP1 * [(A + B) ÷
(A + C)]

 

    12

     

    

 

For purposes of the foregoing
formula, the following definitions shall apply:

 

(A) “CP2”
shall mean the Conversion Price in effect immediately after such issue of Additional Shares of Common Stock;

 

(B) “CP1”
shall mean the Conversion Price in effect immediately prior to such issue of Additional Shares of Common Stock;

 

(C) “A”
shall mean the number of shares of Common Stock outstanding immediately prior to such issue of Additional Shares of Common Stock (treating
for this purpose as outstanding all shares of Common Stock issuable upon exercise of Options outstanding immediately prior to such issue
or upon conversion, exercise or exchange of Convertible Securities (including the Convertible Notes) outstanding (assuming exercise of
any outstanding Options therefor) immediately prior to such issue);

 

(D) “B”
shall mean the number of shares of Common Stock that would have been issued if such Additional Shares of Common Stock had been issued
at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the Issuer in respect of such issue
by CP1); and

 

(E) “C”
shall mean the number of such Additional Shares of Common Stock issued in such transaction. 

 

(iv) Determination
of Consideration.  For purposes of this Section 4.5(f)(iv), the consideration received by the Issuer for the issue
of any Additional Shares of Common Stock shall be computed as follows:

 

(A) Cash and Property.
Such consideration shall:

 

(I) insofar as it consists
of cash, be computed at the aggregate amount of cash received by the Issuer, excluding amounts paid or payable for accrued interest;

 

(II) insofar as it consists
of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the
Board; and

 

(III) in the event Additional
Shares of Common Stock are issued together with other shares or securities or other assets of the Issuer for consideration which covers
both, be the proportion of such consideration so received, computed as provided in clauses (I) and (II) above, as determined in good faith
by the Board.

 

(B) Options and Convertible
Securities.  The consideration per share received by the Issuer for Additional Shares of Common Stock deemed to have been
issued pursuant to Section 4.5(f)(ii), relating to Options and Convertible Securities, shall be determined by dividing:

 

(I) the total amount, if any,
received or receivable by the Issuer as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate
amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein
for a subsequent adjustment of such consideration) payable to the Issuer upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities
and the conversion or exchange of such Convertible Securities, by

 

    13

     

    

 

(II) the maximum number of
shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent
adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or
in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange
of such Convertible Securities.

 

(v) Multiple Closing
Dates.  In the event the Issuer shall issue on more than one date Additional Shares of Common Stock that are a part of one
transaction or a series of related transactions and that would result in an adjustment to the Conversion Price pursuant to the terms of
Section 4.5(f)(iii), then, upon the final such issuance, the Conversion Price shall be readjusted to give effect to all such issuances
as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any
such subsequent issuances within such period).

 

(g) Adjustment
Relating to Trading Price. If, during the period commencing on and including the First Amendment Effective Date and ending on and
including the fifteen (15) month anniversary of the First Amendment Effective Date, there is no thirty (30) consecutive Trading Day-period
during which the average of the Daily VWAPs for such thirty (30) consecutive Trading Day period (after excluding the three (3) highest
and the three (3) lowest Daily VWAPs during such period) equals or exceeds the Threshold Price, the Conversion Price shall be reduced
to an amount equal to the amount that the Conversion Price would otherwise have been had the Conversion Price been $6.00 on the First
Amendment Effective Date (with corresponding adjustments to other terms of this Convertible Note that are based on the Conversion Price,
including, without limitation, the table set forth in the definition of “Redemption Price”).

 

(h) Certificate
of Adjustment. Upon the occurrence of each adjustment or readjustment of the applicable Conversion Price pursuant to this Section
4.5, the Issuer, at its expense, shall promptly, but in any event not later than ten (10) calendar days thereafter, compute such adjustment
or readjustment in accordance with the terms hereof and prepare and furnish to each Holder a certificate, signed by an officer of the
Issuer, setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which
the Convertible Note is convertible) and showing in detail the facts upon which such adjustment or readjustment is based. The Issuer shall,
as promptly as reasonably practicable after the written request at any time of any Holder (but in any event not later than ten (10) calendar
days thereafter), furnish or cause to be furnished to such Holder a certificate setting forth (i) the Conversion Price then in effect,
and (ii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received
upon the conversion of the Convertible Note.

 

(i) Notices of
Record Date. If:

 

(i) the Issuer shall
set a record date for the purpose of entitling the holders of its shares of Common Stock to receive a dividend, or any other distribution,
payable otherwise than in cash;

 

(ii) the Issuer shall
set a record date for the purpose of entitling the holders of its shares of Common Stock to subscribe for or purchase any shares of any
class or other securities or to receive any other rights;

 

(iii) there shall
occur any capital reorganization of the Issuer, reclassification of the shares of the Issuer (other than a subdivision or combination
of its outstanding Common Stock), consolidation or merger of the Issuer with or into another corporation, or conveyance of all or substantially
all of the assets of the Issuer to another corporation; or

 

(iv) there shall occur
a voluntary or involuntary dissolution, liquidation, or winding up of the Issuer;

 

    14

     

    

 

then, and in any such case, the Issuer shall cause
to be sent to the Holders, at least ten (10) calendar days prior to the dates hereinafter specified, a written notice stating (x) the
date which has been set as the record date for the purpose of such dividend, distribution, or rights, or (y) the date on which such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation, or winding up is proposed to take place and the record date
as of which holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property
deliverable upon such reclassification, reorganization, consolidation, merger, conveyance, dissolution, liquidation, or winding up.

 

4.6. Registration,
Exchange and Transfer. The Issuer will keep or will cause to be kept a register in which,
subject to such reasonable regulations as it may prescribe, it will register and transfer the Convertible Notes. No transfer of this
Convertible Note shall be valid as against the Issuer unless made upon such register. This Convertible Note is subject to the restrictions
on transfer set forth on the face hereof. Upon surrender for transfer of this Convertible Note and compliance with said restrictions
on transfer, the Issuer shall execute and deliver in the name of the transferee or transferees a new Convertible Note or Convertible
Notes for a like principal amount. Any new Convertible Note issued upon any registration of transfer or exchange of Convertible Note
shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Convertible Note.

 

This Convertible Note, if
presented for transfer, exchange, redemption or payment, shall (if so required by the Issuer) be duly endorsed by, or be accompanied by
instruments of transfer in form satisfactory to the Issuer duly executed by, the registered Holder or by his duly authorized attorney.

 

Any exchange or transfer shall
be without charge to the Holders, except that the Issuer may require payment of the sum sufficient to cover any processing cost, tax or
governmental charge that may be imposed in relation thereto.

 

Prior to due presentment for
registration of transfer of this Convertible Note, the Issuer may deem and treat the registered Holder hereof as the absolute owner hereof
(whether or not this Convertible Note shall be overdue and notwithstanding any notation of ownership or other writing hereon by anyone
other than the Issuer), for the purpose of receiving payment of or on account of the principal hereof and interest hereon, for the conversion
hereof and for all other purposes, and the Issuer shall not be affected by any notice to the contrary.

 

4.7. Limitations
on Beneficial Ownership. Notwithstanding anything to the contrary contained herein, the
number of shares of Common Stock that may be acquired by the Holder upon any conversion of this Convertible Note (or otherwise in respect
hereof) shall be limited to the extent necessary to insure that, following such conversion (or other issuance), the total number of shares
of Common Stock then beneficially owned by such Holder and its affiliates and any other persons whose beneficial ownership of Common
Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% of the total
number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise)
(unless otherwise expressly agreed by the Holder in writing). For such purposes, beneficial ownership shall be determined in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. This provision shall not restrict the number
of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration
that such Holder may receive in the event of a merger or other business combination or reclassification involving the Issuer. This restriction
may not be waived without the consent of the Holder.

 

    15

     

    

 

5. Defaults and Remedies.

 

5.1. Defaults
and Remedies. An Event of Default shall occur upon the occurrence of any of the events or circumstances specified in Section
6.1 of the Purchase Agreement. In the case of an Event of Default arising from certain events of bankruptcy or insolvency described
in Section 6.1(h) and Section 6.1(i) of the Purchase Agreement, all outstanding Convertible Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is continuing, the Collateral Agent or the Holders of at least
a majority in the aggregate principal amount of the then outstanding Convertible Notes may declare all the Convertible Notes to be due
and payable immediately by notice in writing to the Issuer (with a copy to the Collateral Agent in the case of notice by such Holders)
as further described in Section 6 of the Purchase Agreement specifying the Event of Default. Upon such declaration, the Convertible Notes,
together with accrued and unpaid interest and the other Obligations, shall become due and payable immediately. If the Convertible Notes
are accelerated or otherwise become due and payable prior to the Stated Maturity Date (including the acceleration of claims by operation
of law) as a result of an Event of Default, the amount of principal of, accrued and unpaid interest, Make-Whole Amounts, premiums (if
any) and other Obligations that becomes due and payable with respect to the Convertible Notes shall equal 100% of the Redemption Price
with respect to the Convertible Notes and other Obligations then due as of the date of acceleration. In the case of any Event of Default
occurring by reason of any willful action or inaction taken or not taken by or on behalf of the Issuer or any Guarantor with the intention
of avoiding payment of the Make-Whole Amount or any other amounts or premiums that the Issuer would have had to pay if the Issuer then
had elected to redeem the Convertible Notes pursuant to Section 7, an equivalent amount equal to the applicable Make-Whole Amount
or premiums (if any) shall also become and be immediately due and payable to the extent permitted by Law upon the acceleration of the
Convertible Notes.

 

Holders
may not enforce the Convertible Notes, the Purchase Agreement, or the other Note Documents except as provided in the Purchase Agreement.
Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Convertible Notes may direct the Collateral
Agent in its exercise of any trust or power. If certain conditions specified in the Purchase Agreement are satisfied, Holders of a majority
in aggregate principal amount of the Convertible Notes then outstanding by notice to the Collateral Agent may on behalf of the Holders
of all of the Convertible Notes waive any existing Default or Event of Default and its consequences as provided under the terms of the
Purchase Agreement, except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Convertible
Notes.

 

The
Issuer is required to file periodic certificates with the Collateral Agent and the Holders as to the Issuer’s compliance with the
Note Documents and knowledge or status of any Default as described in the Purchase Agreement.

 

5.2. Waiver;
Rescission of Acceleration. At any time before the date of any declaration accelerating
the maturity of this Convertible Note, the Holders of a majority in aggregate principal amount of then-outstanding Convertible Notes
may waive any Event of Default. Such waivers shall be evidenced by written notice or other document specifying the Event(s) of Default
being waived and shall be binding on all existing or subsequent Holders of outstanding Convertible Notes. At any time after such declaration
of acceleration has been made, and before a judgment or decree for payment of money due has been obtained, the Holders of a majority
in aggregate principal amount of the then-outstanding Convertible Notes may, by written notice to the Issuer, rescind and annul such
declaration.

 

6. Repurchase at Option
of Holders.

 

6.1. Repurchase
at Option of Holders Upon a Fundamental Change.

 

(i) If a Change of
Control or a Termination of Trading (a “Fundamental Change”) occurs at any time prior to the Stated Maturity Date,
the Holder shall have the right, at the Holder’s option, to require the Issuer to repurchase for cash all of the Holder’s
Convertible Notes, or any portion of the principal amount thereof properly surrendered and not validly withdrawn pursuant to Section 6.2
that is equal to $1,000 or an integral multiple of $1,000, on the date (subject to any postponement as set forth in this Section 6.1(i),
the “Fundamental Change Repurchase Date”) specified by the Issuer that is not less than twenty (20) calendar days or
more than thirty-five (35) calendar days following the date of the Fundamental Change Issuer Notice (as defined below) at a repurchase
price equal to 100% of the Redemption Price with respect to the Convertible Notes to be repurchased (the “Fundamental Change
Repurchase Price”). The Fundamental Change Repurchase Date shall be subject to postponement in order to allow the Issuer to
comply with applicable law.

 

    16

     

    

 

(ii) Repurchases of
Convertible Notes under this Section 6.1 shall be made, at the option of the Holder thereof, upon:

 

(A) delivery to the Issuer by
the Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in Exhibit B
attached hereto, on or before the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date,
subject to extension to comply with applicable law; and

 

(B) delivery of the Convertible
Notes to the Issuer at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for
transfer), such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

 

(iii) The Fundamental
Change Repurchase Notice in respect of any Convertible Notes to be repurchased shall state:

 

(A) the portion of the principal
amount of Convertible Notes to be repurchased, which must be in minimum denominations of $1,000 or an integral multiple thereof; and

 

(B) that the Convertible Notes
are to be repurchased by the Issuer pursuant to the applicable provisions of the Convertible Notes.

 

Notwithstanding anything
herein to the contrary, the Holder shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at
any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date (the “Fundamental
Change Expiration Time”) by delivery of a written notice of withdrawal to the Issuer in accordance with Section 6.2.

 

(iv) On or before
the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Issuer shall provide to all Holders a written
notice (the “Fundamental Change Issuer Notice”) of the occurrence of the Fundamental Change, its effective date and
of the repurchase right at the option of the Holders arising as a result thereof. Each Fundamental Change Issuer Notice shall specify:

 

(A) the events causing
the Fundamental Change;

 

(B) the effective date
of the Fundamental Change;

 

(C) the last date on
which the Holder may exercise the repurchase right pursuant to this Section 6;

 

(D) the certificate
number of the Convertible Note to be delivered for repurchase;

 

(E) the Fundamental
Change Repurchase Price;

 

(F) the Fundamental
Change Repurchase Date;

 

    17

     

    

 

(G) the applicable Conversion
Price and any adjustments to the Conversion Price;

 

(H) that the Convertible
Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by the Holder may be converted only if the Holder
withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Convertible Notes; and

 

(I) the procedures that
the Holders must follow to require the Issuer to repurchase their Convertible Notes.

 

No failure of the Issuer to give the
foregoing notices and no defect therein shall limit the Holder’s repurchase rights or affect the validity of the proceedings for
the repurchase of the Convertible Notes pursuant to this Section 6.1. Simultaneously with providing such notice, the Issuer
will publish such information on its website or through such other public medium as the Issuer may use at that time.

 

(v) Notwithstanding
the foregoing, no Convertible Notes may be repurchased by the Issuer on any date at the option of the Holders in connection with a Fundamental
Change if the principal amount of the Convertible Notes has been accelerated, and such acceleration has not been rescinded, on or prior
to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Fundamental Change Repurchase
Price with respect to such Convertible Notes). The Issuer will promptly return to the respective Holders thereof any Convertible Notes
held by it during the acceleration of the Convertible Notes (except in the case of an acceleration resulting from a default by the Issuer
in the payment of the Fundamental Change Repurchase Price with respect to such Convertible Notes), and, upon such return, the Fundamental
Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

 

6.2. Withdrawal
of Fundamental Change Repurchase Notice. A Fundamental Change Repurchase Notice
may be withdrawn by the Holder (in whole or in part) by means of a written notice of withdrawal delivered to the Issuer in accordance
with this Section 6.2 at any time prior to the Fundamental Change Expiration Time, specifying:

 

(i) the principal
amount of the Convertible Notes with respect to which such notice of withdrawal is being submitted, which must be $1,000 or an integral
multiple thereof,

 

(ii) the certificate
number of the Convertible Note in respect of which such notice of withdrawal is being submitted, and

 

(iii) the principal
amount, if any, of such Convertible Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must
be in principal amounts of $1,000 or an integral multiple of $1,000.

 

6.3. Excess Cash Flow Offer.

 

(a) In the event that there
shall be Consolidated Excess Cash Flow for any fiscal year of the Issuer and its Subsidiaries (commencing with the fiscal year ended December
31, 2021), not later than the earlier of (i) the date that is five (5) Business Days after the date of delivery of the annual financial
statements for such fiscal year of the Issuer pursuant to Section 4(a)(ii) of the Purchase Agreement, and (ii) five (5) Business Days
after the date on which the annual financial statements for the applicable fiscal year of the Issuer are required to be delivered pursuant
to Section 4(a)(ii) of the Purchase Agreement, the Issuer will make an offer to purchase Convertible Notes (or a portion thereof), such
offer to be in the form attached hereto as Exhibit C, which shall include, without limitation, a detailed calculation of the Consolidated
Excess Cash Flow for such fiscal year (the “Excess Cash Flow Period”) (each such offer to purchase, an “Excess
Cash Flow Offer”), such offer having an aggregate principal amount equal to:

 

(1) an amount equal to fifty
percent (50%) of Consolidated Excess Cash Flow for the Excess Cash Flow Period then ended; multiplied by

 

    18

     

    

 

(2) a fraction (x) the
numerator of which is equal to the outstanding aggregate principal amount of the Convertible Notes held by such Holder and (y) the
denominator of which is equal to the outstanding aggregate principal amount of the Convertible Notes and all other Priority Lien
Debt required to be repaid with such Consolidated Excess Cash Flow, rounded down to the nearest $1,000 (the “Excess Cash
Flow Offer Amount”). The purchase price for any Excess Cash Flow Offer will be 100% of the sum of (i) the principal amount
then outstanding, plus (ii) any accrued and unpaid interest through the applicable purchase date (the “Excess Cash Flow
Payment”). If the Excess Cash Flow Offer is for less than all of the outstanding Convertible Notes and Convertible Notes
in an aggregate principal amount in excess of the purchase amount are tendered and not withdrawn pursuant to the Excess Cash Flow
Offer, the Issuer will purchase Convertible Notes having an aggregate principal amount equal to the purchase amount on a pro rata
basis, with adjustments so that only Convertible Notes in multiples of $1,000 principal amount (and in a minimum principal amount of
$1,000) will be purchased. Any portion of such Consolidated Excess Cash Flow remaining after consummation of the Excess Cash Flow
Offer may be used for any purpose not otherwise prohibited by the Note Documents.

 

(b) Within the timeframe noted
in (a) above, the Issuer shall send a written offer to each Holder by first class mail or such other notice method provided for in the
Purchase Agreement, which shall govern the terms of the Excess Cash Flow Offer, with a copy of such offer to the Collateral Agent. The
offer shall state:

 

(1) that an Excess
Cash Flow Offer is being made as provided for herein, and that, although Holders are not required to tender their Convertible Notes, all
Convertible Notes (or a portion thereof) that are validly tendered shall be accepted for payment, subject to pro rata reduction as set
forth in Sections 6.3(a) and (e);

 

(2) the principal
amount of Convertible Notes subject to the Excess Cash Flow Offer, the Excess Cash Flow Payment and the expiration date of the Excess
Cash Flow Offer (the “Excess Cash Flow Offer Expiration Date”), which will be no earlier than thirty (30) days and
no later than sixty (60) days after the date such written notice to the Holders and the Collateral Agent is sent and a settlement date
for purchase (the “Excess Cash Flow Payment Date”) not more than five (5) Business Days after the Excess Cash Flow
Offer Expiration Date;

 

(3) that any Convertible
Note (or portion thereof) accepted for payment pursuant to the Excess Cash Flow Offer (and duly paid for on the Excess Cash Flow Payment
Date) shall cease to accrue interest after the Excess Cash Flow Payment Date;

 

(4) that any Convertible
Notes (or portions thereof) not validly tendered shall continue to accrue interest;

 

(5) that any Holder
electing to have a Convertible Note (or portion thereof) purchased pursuant to any Excess Cash Flow Offer shall be required to notify
the Issuer of its election before the close of business on the Excess Cash Flow Offer Expiration Date;

 

(6) that Holders
shall be entitled to withdraw their election if the Issuer receives, not later than the close of business on the Excess Cash Flow Offer
Expiration Date, an electronic transmission or letter setting forth the name of the Holder, the principal amount of the Convertible Note
(or portion thereof) the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Convertible
Note purchased; and

 

    19

     

    

 

(7) the instructions
and any other information necessary to enable Holders to tender their Convertible Notes (or portions thereof) and have such Convertible
Notes (or portions thereof) purchased pursuant to the Excess Cash Flow Offer.

 

(e) On or before the Excess
Cash Flow Payment Date, the Issuer shall, to the extent lawful, accept for payment all Convertible Notes or portions thereof properly
tendered and not withdrawn pursuant to the Excess Cash Flow Offer. Promptly after such acceptance, on the Excess Cash Flow Payment Date,
the Issuer will:

 

(1) deposit by 11:00
a.m., New York City time, with the Holder an amount equal to such Holder’s pro rata share of the Excess Cash Flow Payment in respect
of all Convertible Notes or portions thereof so tendered by such Holder; and

 

(2) deliver or cause
to be delivered an Officer’s Certificate of the Issuer delivered to the Collateral Agent and the Holders stating the aggregate principal
amount of Convertible Notes or portions thereof being purchased by the Issuer.

 

(f) On the Excess Cash Flow
Payment Date, the Issuer shall send to each Holder of Convertible Notes accepted for payment the Excess Cash Flow Payment for such Convertible
Notes, a new Convertible Note (with a copy to the Collateral Agent) in a principal amount equal to the unpurchased portion of the Convertible
Notes surrendered. Interest on the Convertible Notes purchased will cease to accrue on and after the Excess Cash Flow Payment Date.

 

(g) If the aggregate principal
amount of Convertible Notes surrendered in an Excess Cash Flow Offer exceeds the Excess Cash Flow Offer Amount, the Issuers will select
the Convertible Notes to be purchased on a pro rata basis with such adjustments as needed so that no Convertible Notes in an unauthorized
denomination are purchased in part based on the aggregate principal amount, as applicable of the Convertible Notes tendered.

 

6.4. Excess Proceeds
Offer.

 

(a) Not later than
five (5) days after the date of receipt by the Issuer or any of its Subsidiaries of

 

(i) any Net Cash Proceeds
from the issuance of any Indebtedness of the Issuer and its Subsidiaries (other than Permitted Indebtedness) (such Net Cash Proceeds,
“Debt Issuance Net Proceeds”),

 

(ii) any Net Cash
Proceeds from any Asset Disposition (to the extent the total aggregate amount of such Net Cash Proceeds received by the Issuer and/or
its Subsidiaries in the same fiscal year (and not paid to the Holders of the Convertible Notes and/or other Priority Lien Debt to repay
Priority Lien Obligations) are in excess of One Hundred Thousand Dollars ($100,000)) (such excess, the “Excess Asset Disposition
Net Proceeds”),

 

(iii) any Net Cash
Proceeds from any insurance or condemnation awards (once the total aggregate amount of such Net Cash Proceeds received by the Issuer and
its Subsidiaries in such fiscal year (and not paid to the Holders of Convertible Notes as a repurchase of the Convertible Notes and/or
a repayment of other Priority Lien Debt) exceeds One Hundred Thousand Dollars ($100,000) (and to the extent repurchase is required, the
required amount of such repurchase shall only be the net Cash Proceeds in excess of such amount (such excess, the “Excess Condemnation
Net Proceeds”), and (ii) if the Issuer notifies the Agent of the Issuer’s or of its Subsidiaries’ intent to reinvest
such Net Cash Proceeds on or prior to the fifth day after such receipt of Net Cash Proceeds then so long as no Default or Event of Default
shall have occurred or be continuing at the time of such notice, at the time of reinvestment, or at any time in between, and (y) the proceeds
of such insurance and/or condemnation award are held in a Controlled Account, the Issuer shall have the option, directly or through one
or more Guarantors or its Subsidiaries, to use such Net Cash Proceeds to reinvest in similar productive assets of the business, in each
case, (x) that are used or useful in the business of the Issuer and its Subsidiaries and (y) that comprise Collateral to the extent such
property or asset sold or otherwise disposed of was Collateral, within one hundred and eighty (180) days of receipt of such Net Cash Proceeds
(or if Issuer or the applicable Subsidiary enters into a binding commitment to reinvest such proceeds not later than the end of such one
hundred and eighty (180) day period with the good faith expectation that such proceeds will be applied to satisfy such reinvestment commitment
within the next one hundred eighty (180) days, an extension for a period of up to an additional one hundred eighty (180) days from the
end of the initial one hundred and eighty (180) day period) (the “Reinvestment Period”) and until the end of the Reinvestment
Period, such insurance and/or condemnation awards shall not be considered Excess Condemnation Net Proceeds) or

 

    20

     

    

 

(iv) any cash, Cash
Equivalents or other proceeds from any capital contributions to, or issuances or other sales of or transactions with respect to any Equity
Interests of the Issuer or any of its Subsidiaries resulting in gross proceeds in excess of Seventy-Five Million Dollars ($75,000,000)
in the aggregate in any six (6) month period after (but not including) the Closing Date (other than Equity Interests issued (A) pursuant
to any employee stock or stock option compensation plan, (B) upon the Consummation of the Merger on the Closing Date as a result of the
equity contribution occurring in connection therewith, (C) pursuant to the terms of the Convertible Note and the Purchase Agreement in
order to purchase, redeem, convert or otherwise exchange the Convertible Notes in accordance with the terms of thereof), or (D) for purposes
approved in writing by the Agent (such excess, “Excess Equity Issuance Net Proceeds”).

 

(each of the events set forth
in the foregoing clauses (i), (ii), (iii) and (iv), a “Mandatory Prepayment Event”), the Issuer will be obligated
to make an offer in the form attached hereto as Exhibit D (such offer, a “Mandatory Prepayment Offer”) to the
Holders of the Convertible Notes to purchase Convertible Notes (or a portion thereof) in an amount equal to 100% of the aggregate Convertible
Notes Allocable Share of all such Excess Proceeds, plus accrued and unpaid interest on the aggregate principal amount of Convertible Notes
to be prepaid to, but excluding, the date of purchase plus the applicable Make-Whole Amount (unless such Excess Proceeds derive from Excess
Condemnation Net Proceeds, in which case the applicable Make-Whole Amount shall not be included) (the “Mandatory Prepayment Offer
Payment Amount”). If the Mandatory Prepayment Offer is for less than all of the outstanding Convertible Notes and Convertible
Notes in an aggregate principal amount in excess of the purchase amount are tendered and not withdrawn pursuant to the Mandatory Prepayment
Offer, the Issuer will purchase Convertible Notes having an aggregate principal amount equal to the purchase amount on a pro rata basis,
with adjustments so that only Convertible Notes in multiples of $1,000 principal amount (and in a minimum principal amount of $1,000)
will be purchased. Any portion of such Excess Proceeds remaining after consummation of the Mandatory Prepayment Offer may be used for
any purpose not otherwise prohibited by the Note Documents.

 

(b) Within the timeframe
noted in (a) above, the Issuer shall send a written offer to each Holder by first class mail or such other notice method provided for
in the Purchase Agreement, which shall govern the terms of the Mandatory Prepayment Offer, with a copy of such offer to the Collateral
Agent. The offer shall state:

 

(1) that a Mandatory
Prepayment Offer is being made as provided for herein, and that, although Holders are not required to tender their Convertible Notes,
all Convertible Notes (or a portion thereof) that are validly tendered shall be accepted for payment, subject to pro rata reduction as
set forth in Sections 6.4(a) and (e);

 

(2) the principal
amount of Convertible Notes subject to the Mandatory Prepayment Offer, the Mandatory Prepayment Offer Amount and the nature and amount
of the Excess Proceeds and the expiration date of the Mandatory Prepayment Offer (the “Mandatory Prepayment Offer Expiration
Date”), which will be no earlier than thirty (30) days and no later than sixty (60) days after the date such written notice
to the Holders and the Collateral Agent is sent and a settlement date for purchase (the “Mandatory Prepayment Date”)
not more than five (5) Business Days after the Mandatory Prepayment Offer Expiration Date;

 

    21

     

    

 

(3) that any Convertible
Note (or portion thereof) accepted for payment pursuant to the Mandatory Prepayment Offer (and duly paid for on the Mandatory Prepayment
Date) shall cease to accrue interest after the Mandatory Prepayment Date;

 

(4) that any Convertible
Notes (or portions thereof) not validly tendered shall continue to accrue interest;

 

(5) that any Holder
electing to have a Convertible Note (or portion thereof) purchased pursuant to a Mandatory Prepayment Offer shall be required to notify
the Issuer of its election before the close of business on the Mandatory Prepayment Offer Expiration Date;

 

(6) that Holders
shall be entitled to withdraw their election if the Issuer receives, not later than the close of business on the Mandatory Prepayment
Offer Expiration Date, an electronic transmission or letter setting forth the name of the Holder, the principal amount of the Convertible
Note (or portion thereof) the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such
Convertible Note purchased; and

 

(7) the instructions
and any other information necessary to enable Holders to tender their Convertible Notes (or portions thereof) and have such Convertible
Notes (or portions thereof) purchased pursuant to the Mandatory Prepayment Offer.

 

(e) On or before the Mandatory
Prepayment Date, the Issuer shall, to the extent lawful, accept for payment all Convertible Notes or portions thereof properly tendered
and not withdrawn pursuant to the Mandatory Prepayment Offer. Promptly after such acceptance, on the Mandatory Prepayment Date, the Issuer
will:

 

(1) deposit by 11:00

all Convertible Notes or portions thereof so tendered by such Holder; and

to be delivered an Officer’s Certificate of the Issuer delivered to the Collateral Agent and the Holders stating the aggregate principal

(f) On the Mandatory Prepayment
Date, the Issuer shall send to each Holder of Convertible Notes accepted for payment the Excess Proceeds for such Convertible Notes and
a new Convertible Note (with a copy to the Collateral Agent) in a principal amount equal to the unpurchased portion of the Convertible
Notes surrendered. Interest on the Convertible Notes purchased will cease to accrue on and after the Mandatory Prepayment Date.

 

(g) If the aggregate principal
amount of Convertible Notes surrendered in a Mandatory Prepayment Offer exceeds the Mandatory Prepayment Offer Amount, the Issuers will
select the Convertible Notes to be purchased on a pro rata basis with such adjustments as needed so that no Convertible Notes in an unauthorized
denomination are purchased in part based on the aggregate principal amount, as applicable of the Convertible Notes tendered.

 

6.5. Term Loan Repayment Offer.

 

(a) Not later than
thirty (30) days after each date on which there is a voluntary prepayment, repayment or repurchase of the loans under the Term Loan Credit
Agreement or any other Priority Lien Obligation, the Issuer will make an offer, with such offer to be in the form attached hereto as Exhibit
E, to purchase the Convertible Notes (or a portion thereof) in an aggregate principal amount up to the aggregate principal amount
of Priority Lien Debt repurchased or prepaid (the “Term Loan Offer Amount”) at a price that, as a percentage of the
principal acquired, is the same as the price paid in the repurchase or repayment of the Priority Lien Debt (each such offer, a “Term
Loan Repayment Offer” and such payment shall include accrued and unpaid interest, if any, to, but excluding, the date of purchase
plus the Make-Whole Amount, any such payment, a “Term Loan Payment”). If the Term Loan Repayment Offer is for less
than all of the outstanding Convertible Notes and Convertible Notes in an aggregate principal amount in excess of the purchase amount
are tendered and not withdrawn pursuant to the Term Loan Repayment Offer, the Issuer will purchase Convertible Notes having an aggregate
principal amount equal to the purchase amount on a pro rata basis, with adjustments so that only Convertible Notes in multiples of $1,000
principal amount (and in a minimum principal amount of $1,000) will be purchased. Any portion of such Term Loan Payment remaining after
consummation of the Term Loan Repayment Offer may be used for any purpose not otherwise prohibited by the Note Documents.

 

    22

     

    

 

(b) Not later than thirty
(30) days following any voluntary prepayment, repayment or repurchase of the loans under the Term Loan Credit Agreement or, as the context
may require, other Priority Lien Obligation, the Issuer shall send a written offer to each Holder by first class mail or by such other
manner provided for in the Purchase Agreement, which shall govern the terms of the Term Loan Repayment Offer, with a copy of such offer
to the Collateral Agent. The offer shall state:

 

(1) that a voluntary
prepayment, repayment or repurchase of the loans under the Term Loan Credit Agreement, or as the context may require, such other Priority
Lien Obligation, has occurred and a Term Loan Repayment Offer is being made as provided for herein, and that, although Holders are not
required to tender their Convertible Notes (or a portion thereof), all Convertible Notes that are validly tendered shall be accepted for
payment, subject to pro rata reduction as set forth in Sections 6.5(a) and (e);

 

(2) the Term Loan
Payment and the expiration date of the Term Loan Repayment Offer (the “Term Loan Repayment Offer Expiration Date”),
which will be no earlier than thirty (30) days and no later than sixty (60) days after the date such written notice to the Holders and
the Collateral Agent is sent and a settlement date for purchase (the “Term Loan Payment Date”) not more than five (5)
Business Days after the Term Loan Repayment Offer Expiration Date;

 

(3) that any Convertible
Note (or portion thereof) accepted for payment pursuant to the Term Loan Repayment Offer (and duly paid for on the Term Loan Payment Date)
shall cease to accrue interest after the Term Loan Payment Date;

 

(4) that any Convertible
Notes (or portions thereof) not validly tendered shall continue to accrue interest;

 

(5) that any Holder
electing to have a Convertible Note (or portion thereof) purchased pursuant to any Term Loan Repayment Offer shall notify the Issuer of
its election to the Issuer at the address specified in the notice at before the close of business on the Term Loan Repayment Offer Expiration
Date;

 

(6) that Holders
shall be entitled to withdraw their election if the Issuer receives, not later than the close of business on the Term Loan Repayment Offer
Expiration Date, an electronic transmission or letter setting forth the name of the Holder, the principal amount of the Convertible Note
(or portion thereof) the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Convertible
Note purchased; and

 

(7) the instructions
and any other information necessary to enable Holders to tender their Convertible Notes (or portions thereof) and have such Convertible
Notes (or portions thereof) purchased pursuant to the Term Loan Repayment Offer.

 

If the Term Loan Repayment
Offer is sent prior to the voluntary prepayment, repayment or repurchase of the loans under the other Priority Lien Documents, it may
be conditioned upon the consummation of the voluntary prepayment, repayment or repurchase of the loans under the Term Loan Credit Agreement.

 

    23

     

    

 

(c) On or before the Term
Loan Payment Date, the Issuer shall, to the extent lawful, accept for payment all Convertible Notes or portions thereof properly tendered
and not withdrawn pursuant to the Term Loan Repayment Offer. Promptly after such acceptance, on the Term Loan Payment Date, the Issuer
will:

 

(1) deposit by 11:00
a.m., New York City time, with the Holder an amount equal to such Holder’s pro rata share of the Term Loan Repayment Offer in respect
of all Convertible Notes or portions thereof so tendered by such Holder; and

 

(2) deliver or cause
to be delivered an Officer’s Certificate of the Issuer delivered to the Collateral Agent and the Holders stating the aggregate principal
amount of Convertible Notes or portions thereof being purchased by the Issuer.

 

(d) On the Term Loan Payment
Date, the Issuer shall send to each Holder of Convertible Notes accepted for payment the Term Loan Payment for such Convertible Notes
and a new Convertible Note (with a copy to the Collateral Agent) in a principal amount equal to the unpurchased portion of the Convertible
Notes surrendered. Interest on the Convertible Notes purchased will cease to accrue on and after the Term Loan Payment Date.

 

(e) If the aggregate principal
amount of Convertible Notes surrendered in a Term Loan Repayment Offer exceeds the Term Loan Offer Amount, the Issuers will select the
Convertible Notes to be purchased on a pro rata basis with such adjustments as needed so that no Convertible Notes in an unauthorized
denomination are purchased in part based on the aggregate principal amount, as applicable of the Convertible Notes tendered.

 

6.6. Covenant to Comply with Applicable
Laws Upon Repurchase of Convertible Notes. In connection with any repurchase offer upon
a Fundamental Change, Excess Cash Flow Offer, Mandatory Prepayment Offer or a Term Loan Repayment Offer pursuant to this Section 6,
the Issuer will, if required:

 

(i) comply with the
provisions of any tender offer rules under the Exchange Act that may then be applicable;

 

(ii) file a Schedule TO
or any other required schedule under the Exchange Act; and

 

(iii) otherwise comply
with all federal and state securities laws in connection with any offer by the Issuer to repurchase the Convertible Notes;

 

in each case, so as to permit the rights
and obligations under this Section 6 to be exercised in the time and in the manner specified in this Section 6 subject to
postponement in order to allow the Issuer to comply with applicable law. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Convertible Note relating to the Issuer’s obligations to purchase this Convertible Note upon
a Fundamental Change, Excess Cash Flow Offer, Mandatory Prepayment Offer or a Term Loan Repayment Offer, the Issuer will comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions of this Convertible
Note by virtue of such conflict.

 

6.7. Offers
with Declined Proceeds. If a holder of a Convertible Note or of any other Priority Lien
Debt declines all or any portion of the payments the Issuer would have been required to make or offer to the holders of Priority Lien
Debt on a pro rata and pari passu basis with an Excess Cash Flow Offer, Excess Proceeds Offer or Term Loan Repayment Offer under
this Convertible Note (any such declined amounts, “Declined Proceeds” and any such declining holder of Priority Lien
Debt, a “Declining Holder” and all other holders of Priority Lien Debt, “Non-Declining Holders”),
then such Declined Proceeds shall be offered and paid to the Non-Declining Holders in accordance with their pro rata share of the Priority
Lien Obligations until all of the remaining Declined Proceeds have been depleted. It being understood that for purposes of this Convertible
Note, any such Declined Proceeds shall be treated in the same manner as the original proceeds and the same Excess Cash Flow Offer, Excess
Proceeds Offer and Term Loan Repayment Offer mechanics described in this Section 6 shall apply thereto, provided however, for the purposes
of determining when such Declined Proceeds are required to be offered to any Non-Declining Holders, the date of receipt of such proceeds
by the Note Parties shall be the first Business Day after the last day that a Declining Holder under any Priority Lien Obligation has
the right to decline their share of such proceeds (for example, if a Priority Lien Holder has a right to accept or decline such proceeds
of an Asset Disposition for sixty (60) days under this Convertible Note and five (5) days under other Priority Lien Debt, then the first
day that such Declined Proceeds would be required to be offered to the other Non-Declining Holders would be the first Business Day after
the sixty (60) day period allowed under such Priority Lien Obligations).

 

    24

     

    

 

7. Optional Redemption.

 

7.1. Optional
Redemption Upon Triggering Event.

 

(a) On or after August
13, 2023, the Issuer may redeem all or any portion of the Convertible Note, at any time following a Triggering Event ending on, and including,
the Trading Day immediately preceding the date on which the Issuer provides the Notice of Optional Redemption (an “Optional Redemption
Notice Date”) (the “Optional Redemption”) by paying to the Holder the Redemption Price in the form of additional
stock, cash or a combination thereof.

 

7.2. Notice of
Optional Redemption.

 

(a) In case the Issuer
exercises its Optional Redemption right pursuant to Section 7.1, it shall fix a date for Optional Redemption (each, an “Optional
Redemption Date”) and it shall deliver or cause to be delivered a written notice of such Optional Redemption (a “Notice
of Optional Redemption”) not less than thirty (30) nor more than sixty (60) Trading Days prior to the Optional Redemption Date
to each Holder of Convertible Notes so to be redeemed as a whole or in part. Simultaneously with providing a Notice of Optional Redemption,
the Issuer shall publish, or cause to be published, a notice containing the information set forth in such Notice of Optional Redemption
on the Issuer’s website or through such other public medium as the Issuer may use at that time. A Notice of Optional Redemption
shall be irrevocable.

 

(b) If any Notice
of Optional Redemption has been given in respect of the Convertible Notes in accordance with this Section 7.2, the Convertible
Notes shall become immediately due and payable on the Optional Redemption Date at the place or places stated in the Notice of Optional
Redemption and at the applicable Redemption Price.

 

(c) Each Notice of
Optional Redemption shall specify:

 

(i) the Optional
Redemption Date;

 

(ii) the Redemption
Price;

 

(iii) that on the
Optional Redemption Date, the Redemption Price will become due and payable;

 

(iv) the place or
places where such Convertible Notes are to be surrendered for payment of the Redemption Price;

 

(v) that Holders may

Date, upon surrender of such Convertible Note, a new Convertible Note in principal amount equal to the unredeemed portion thereof shall
be issued.

 

7.3. Restriction
on Optional Redemption. The Issuer may not redeem any Convertible Notes on any date if the principal amount of the Convertible Notes
has been accelerated in accordance with the terms herein, and such acceleration has not been rescinded, on or prior to the Optional Redemption
Date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect
to such Convertible Notes). 

 

For the purposes of this Section 7, any
capitalized terms used herein but not otherwise defined in this Convertible Note shall have the respective meanings ascribed to them in
the Term Loan Credit Agreement.

 

    25

     

    

 

8. Restrictions on Transfer.

 

8.1. Restricted
Securities. By acceptance hereof, the Holder understands and agrees that this Convertible
Note and the Common Stock receivable upon conversion hereof are characterized as “restricted securities” under the Securities
Act inasmuch as they are being acquired from the Issuer in a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances.
In this connection, the Holder represents that it is familiar with Rule 144 promulgated by the Securities and Exchange Commission, as
presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

 

8.2. [Reserved]

 

8.3. Legends.
It is understood that, until the date that is the later of (1) the date that is one year after the last date of original issuance of
the Convertible Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such later
date, if any, as may be required by applicable law, each Convertible Note and each certificate evidencing Common Stock acquired upon
conversion thereof (or evidencing any other securities issued with respect thereto) shall bear the following legend (unless such Convertible
Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act
and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule
144 or any similar provision then in force under the Securities Act), or unless otherwise agreed by the Issuer in writing:

 

[THIS CONVERTIBLE NOTE HAS / THE SECURITIES
REPRESENTED BY THIS CERTIFICATE HAVE] NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”),
OR ANY APPLICABLE STATE SECURITIES LAWS. SUCH SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND MAY NOT BE OFFERED FOR SALE, SOLD,
DELIVERED AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FILED BY THE ISSUER WITH
THE U.S. SECURITIES AND EXCHANGE COMMISSION COVERING SUCH SECURITIES UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL SATISFACTORY TO
THE ISSUER THAT SUCH REGISTRATION IS NOT REQUIRED.

 

Any Convertible Note (or security issued in exchange
or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has
been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and
that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided
by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Convertible Note for exchange
to the Issuer, be exchanged for a new Convertible Notes, of like tenor and aggregate principal amount, which shall not bear the aforementioned
restricted legend required.

 

9. Notices.

 

9.1. Notices
to Holder of Convertible Notes. Any notice required by the provisions of this Convertible
Note to be given to the Holder shall be in writing and may be delivered by any means (including personal delivery, expedited courier,
messenger service, fax, ordinary mail or electronic mail), but no such notice, request, demand, claim or other communication will be
deemed to have been duly given unless and until it actually is received by the intended recipient.

 

    26

     

    

 

9.2. Notices
to the Issuer. Whenever any provision of this agreement requires a notice to be given
to the Issuer by the Holder, the holder of Common Stock obtained upon the conversion of a Convertible Note or the holder of any other
security of the Issuer obtained in connection with a recapitalization, merger, dividend or other event affecting a Convertible Note,
then and in each such case, such notice shall be in writing and may be delivered by any means (including personal delivery, expedited
courier, messenger service, fax, ordinary mail or electronic mail), but no such notice, request, demand, claim or other communication
will be deemed to have been duly given unless and until it actually is received by the Issuer.

 

No notice under this Section 9.2 shall
be valid unless signed by the holder of the Convertible Note, Common Stock or other security giving the notice or in the case of a notice
by holders of a specified percent in aggregate principal amount of outstanding Convertible Notes unless signed by each holder of a Convertible
Note whose Convertible Note has been counted in constituting the requisite percentage of Convertible Notes required to give such notice.

 

10. No Rights as Stockholder.
This Convertible Note, as such, shall not entitle the Holder to any voting rights or other rights as a stockholder of the Issuer.

 

11. Headings, Governing
Law, Purchase Agreement to Control. The descriptive headings in this Convertible Note
are inserted for convenience only and do not constitute a part of this Convertible Note. The validity, meaning and effect of this
Convertible Note shall be determined in accordance with the laws of the State of New York without regard for its conflicts of laws principles,
except Section 5-1401 of the New York General Obligations Law. In the case of a conflict between the provisions of this Convertible Note
and the Purchase Agreement, the provisions of the Purchase Agreement shall control.

 

12. Severability. Whenever
possible, each provision hereof shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision
hereof is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition
or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof. If a court of competent jurisdiction
should determine that a provision hereof would be valid or enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as shall be necessary to render the provision in question
effective and valid under application law.

 

13. Additional Amounts.
All payments and deliveries made by or on behalf of the Issuer or any of the Guarantors (including, in each case, any successor entity)
under or with respect to the Convertible Notes or any other Note Document shall be made free and clear of, and without withholding or
deduction for, or on account of, any present or future Taxes, unless such withholding or deduction is required by applicable Laws. If
any applicable Law requires the deduction or withholding of any Tax from any such payment (as determined in the good faith discretion
of the Issuer, any Guarantor, or any other applicable withholding agent), then the applicable withholding agent shall be entitled to make
such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance
with applicable law and if such Tax is an Indemnified Tax, then the sum payable to the Holder shall be increased by such Additional Amounts
as may be necessary so that after making such deduction or withholding (including such deductions and withholdings applicable to the Additional
Amounts), the beneficial owner of the Convertible Notes receives an amount equal to the sum it would have received had no such deduction
or withholding been made. The Issuer or the relevant Guarantor shall use its reasonable efforts to obtain Tax receipts from each Governmental
Authority evidencing the payment of any Taxes so deducted or withheld. The Issuer or the relevant Guarantor shall furnish to the Holder,
within sixty (60) days after the date the payment of any Taxes so deducted or withheld is made, certified copies of Tax receipts evidencing
payment by the Issuer or a Guarantor, as the case may be, a copy of any return reporting such payment or other evidence of such payment
reasonably satisfactory to the Holder.

 

    27

     

    

 

14. Mutilated, Destroyed,
Lost or Stolen Notes. In case any Convertible Note shall become mutilated or be destroyed,
lost or stolen, the Issuer shall execute and deliver a new Convertible Note in exchange and substitution for the mutilated Convertible
Note, or in lieu of and in substitution for the Convertible Note so destroyed, lost or stolen. In every case the applicant for a substituted
Note shall furnish to the Issuer such security or indemnity as may be required by it to hold it harmless from any loss, liability, cost
or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Issuer evidence to its satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. No service
charge shall be imposed by the Issuer upon the issuance of any substitute Convertible Note, but the Issuer may require a Holder to pay
a sum sufficient to cover any documentary, stamp, or similar issue or transfer tax required in connection therewith as a result of the
name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was
destroyed, lost or stolen. Every substitute Convertible Note issued pursuant to the provisions of this Section 14 by virtue of
the fact that any Convertible Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer,
whether or not the destroyed, lost or stolen Convertible Note shall be found at any time, and shall be entitled to all the benefits of
(but shall be subject to all the limitations set forth in) this Convertible Note equally and proportionately with any and all other Convertible
Notes duly issued under the Purchase Agreement. To the extent permitted by law, all Convertible Notes shall be held and owned upon the
express condition that the foregoing provisions are exclusive with respect to the replacement, payment, redemption, conversion or repurchase
of mutilated, destroyed, lost or stolen Convertible Notes and shall preclude any and all other rights or remedies notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, conversion or repurchase
of negotiable instruments or other securities without their surrender.

 

15. Remedies.
Holder shall have, in addition to the rights and remedies contained in this Convertible Note, all of the rights and remedies of a creditor,
now or hereafter available at law or in equity. Holder may, at its option, exercise any one or more of such rights and remedies individually,
partially, or in any combination. No right, power, or remedy conferred upon Holder shall be exclusive of any other right, power, or remedy
referred to herein or now or hereafter available at law or in equity. In addition to all other amounts payable upon an Event of Default,
the Issuer shall reimburse Holder for all of its out of pocket expenses (including reasonable legal fees) incurred in the enforcement
of Holder’s rights and remedies in respect of this Convertible Note.

 

16. [Amendment and Restatement.
THIS CONVERTIBLE NOTE IS ISSUED IN SUBSTITUTION FOR, AND AMENDS AND RESTATES, SUPERSEDES AND CONTROLS IN ENTIRETY OVER THAT CERTAIN SENIOR
SECURED CONVERTIBLE NOTE MADE BY THE ISSUER PAYABLE TO THE ORDER OF [__], DATED AUGUST 13, 2021, AND THIS CONVERTIBLE NOTE DOES NOT DISCHARGE,
