I.


 


Section
1.01 Principal and Interest. `


 


(a)
FOR VALUE RECEIVED, Puradigm, LLC, a Nevada limited liability company (the “Borrower”) hereby
promises to pay to the order of DSS PureAir, Inc., a Texas corporation (together with its successors and assigns, the “Holder”),
in lawful money of the United States of America and in immediately available funds, the principal sum of Five Million 00/100
Dollars ($5,000,000.00) (the “Maximum Principal Amount”),
or such amounts as may be advanced from time to time by Holder to or for the account of the Borrower under this Note (each
such amount being an “Advance” and more than one such amounts being “Advances”), with such
principal amounts and accrued interest to be due on May 14, 2023 (the “Maturity Date”), subject to earlier
conversion of this Note as provided herein. The Borrower authorizes and appoints the Holder to enter each borrowing and repayment
of principal under this Note on Schedule A without any further authorization on the part of the Borrower or any endorser or guarantor
of this Note, and to the extent interest is not paid when due, the Holder is authorized and directed to enter the amount of such
interest as an additional borrowing of principal under this Note on the Schedule A, and the Borrower agrees that such entries
shall be conclusive evidence of the principal balance due under this Note at any time, absent manifest error. The Holder’s
failure to make an entry, however, shall not limit or otherwise affect the obligations of the Borrower or any endorser or guarantor
of this Note.


 




    	 



    	 



    

 


(b)
Advances; Advance Requests; Advance Form.


 


(i)
 Subject to the terms and conditions of the Purchase Agreement, Holder shall make Advances under this Note in the amounts,
at the times, and to the accounts requested by the Borrower from time to time, in each case upon delivery to Holder of a written
request by the Borrower for an Advance under this Note, in the form of request attached to the Purchase Agreement as Exhibit A
thereto (each such request being an “Advance Request”), completed as prescribed in the Purchase Agreement;
provided, however, that the aggregate principal amount of all Advances made under this Note
may not exceed the Maximum Principal Amount. 


 


(ii)
To be effective, an Advance Request must be received by Holder on or before the third Business Day before the particular calendar
date specified in such Advance Request that the Borrower requests to be the date on which the respective Advance is to be made.


 


(iii)
The Borrower hereby agrees that Holder, for its purposes, may consider any Advance Request approved by or on behalf of the authorized
officers of the Borrower and delivered to Holder in accordance with the terms of the Purchase Agreement to be an accurate representation
of the Borrower’s request for an Advance under this Note and the Borrower’s approval of that Advance Request


 


(c)
Interest Rate: Interest on the outstanding principal of each Advance shall accrue from the date on which the respective Advance
is made to the date on which such principal is due. Interest on each Advance shall be computed on the basis of (1) actual days
elapsed from (but not including) the date on which the respective Advance is made (for the first payment of interest due under
this Note for the respective Advance) or the date on which the payment of interest was last due (for all other payments of interest
due under this Note for the respective Advance), to (and including) the date on which payment is next due, and (2) a year of 360
days. The interest rate applicable to each Advance shall bear interest at six and sixty-five hundredths percent (6.65%) per annum.


 


(d)
Maximum Lawful Interest: The term “Maximum Lawful Rate” means the maximum rate of interest and the term “Maximum
Lawful Amount” means the maximum amount of interest that is permissible under applicable state or federal law for the type
of loan evidenced by this Note. If applicable state or federal law does not permit a higher interest rate, the “weekly ceiling”
(as defined in Chapter 303 of the Texas Finance Code) shall be the interest rate ceiling applicable to this Note and shall be
the basis for determining the Maximum Lawful Rate in effect from time to time during the term of this Note. If applicable state
or federal law allows a higher interest rate or federal law preempts the state law limiting the rate of interest, then the foregoing
interest rate ceiling shall not be applicable to this Note. If the interest rate ceiling is increased by statute or other governmental
action subsequent to the date of this Note, then the new interest rate ceiling shall be applicable to this Note from the effective
date thereof, unless otherwise prohibited by applicable law.


 


(e)
Spreading of Interest: Holder does not intend to contract for, charge or receive more than the Maximum Lawful Rate or Maximum
Lawful Amount permitted by applicable state or federal law, and to prevent such an occurrence Holder and Borrower agree that all
amounts of interest, whenever contracted for, charged or received by Holder, with respect to the loan of money evidenced by this
Note, shall be spread, prorated or allocated over the full period of time this Note is unpaid, including the period of any renewal
or extension of this Note. If demand for payment of this Note is made by Holder prior to the full stated term, the total amount
of interest contracted for, charged or received to the time of such demand shall be spread, prorated or allocated along with any
interest thereafter accruing over the full period of time that this Note thereafter remains unpaid for the purpose of determining
if such interest exceeds the Maximum Lawful Amount.


 




    	2



    	 



    

 


(f)
Excess Interest: At Maturity or on earlier final payment of this Note, Holder shall compute the total amount of interest that
has been contracted for, charged or received by Holder or payable by Borrower under this Note and compare such amount to the Maximum
Lawful Amount that could have been contracted for, charged or received by Holder. If such computation reflects that the total
amount of interest that has been contracted for, charged or received by Holder or payable by Borrower exceeds the Maximum Lawful
Amount, then Holder shall apply such excess to the reduction of the principal balance and not to the payment of interest; or if
such excess interest exceeds the unpaid principal balance, such excess shall be refunded to Borrower. This provision concerning
the crediting or refund of excess interest shall control and take precedence over all other agreements between Borrower and Holder
so that under no circumstances shall the total interest contracted for, charged or received by Holder exceed the Maximum Lawful
Amount.


 


(g)
Interest After Default: At Holder’s option, and to the extent permitted by applicable law, the unpaid principal balance
shall bear interest after default and after maturity (whether by acceleration or otherwise) at the Default Interest Rate. The
“Default Interest Rate” shall be, at Holder’s option, a) eighteen percent (18%) per annum, or b) such lesser
rate of interest as Holder in its sole discretion may choose to charge; but never more than the Maximum Lawful Rate or at a rate
that would cause the total interest contracted for, charged or received by Holder to exceed the Maximum Lawful Amount.


 


(h)
Daily Computation of Interest: To the extent permitted by applicable law, Holder at its option may either c) calculate the per
diem interest rate or amount based on the actual number of days in the year (365 or 366, as the case may be), and charge that
per diem interest rate or amount each day, or d) calculate the per diem interest rate or amount as if each year has only 360 days,
and charge that per diem interest rate or amount each day for the actual number of days of the year (365 or 366 as the case may
be). If this Note calls for monthly or quarterly payments, Holder at its option may determine the payment amount based on the
assumption that each year has only 360 days and each month has 30 days. In no event shall Holder compute the interest in a manner
that would cause Holder to contract for, charge or receive interest that would exceed the Maximum Lawful Rate or the Maximum Lawful
Amount.


 


(i)
Except as otherwise set forth in this Note, the Borrower may prepay any portion of the principal amount of this Note any time
following but not prior to the one year anniversary of the Original Issue Date (the “Prepayment Period”). During the
Prepayment Period, the Borrower shall have the right to prepay this Note in whole or in part at any time for cash on 10 business
days’ written notice, subject to the right of Holder to convert this Note in accordance with Section 1.03. The Borrower
shall honor any Conversion Notice (as defined in Section 1.03) delivered by the Holder up to 10 business days following the notice
of prepayment.


 


Section
1.02 Reference to Certain Agreements. The obligations of the Borrower under this Note are secured pursuant to the Security
Agreement of even date herewith (“Security Agreement”) among the Borrower and the Holder. In addition, this
Note is the “Note” referred to in, and entitled to the benefits of, the Securities
Purchase Agreement dated as of even date herewith, made by and among Holder and the Borrower (such agreement, as it may be amended,
supplemented, and restated from time to time in accordance with its terms, being the “Purchase Agreement”).

Section
1.03 Optional Conversion. At any time, before or after the occurrence of an Event of Default, the Holder shall be entitled,
at its option, to convert all, or a portion of all, of the outstanding principal amount of this Note, plus accrued but unpaid
interest thereon, into a number of newly issued membership units of the Borrower (the “Borrower Securities”),
with the Maximum Principal Amount and all outstanding interest equal to eighteen percent (18%) of the total number of Borrower
Securities that will be outstanding upon such conversion, calculated on a fully-diluted basis, giving effect to the exercise,
exchange or conversion of all options, warrants, convertible debt and any other securities or instruments exercisable or exchangeable
for or convertible into Borrower Securities, whether or not then vest or immediately exercisable or exchangeable for or convertible.
Any partial conversion shall use the same eighteen percent (18%) ratio and percentage based on the amount of the outstanding principal
amount being converted as compared to Maximum Principal Amount. The Membership Units
issuable from time to time by the Borrower upon a conversion hereunder are referred to herein as the “Conversion Units.”
Upon any conversion pursuant to this Note, Holder shall execute a joinder to the Borrower’s Operating Agreement, or any
similar successor document to the Operating Agreement, and shall hold the Conversion Units subject to all the terms and conditions
of the Operating Agreement, except for the express exceptions to same set forth in the Transaction Documents


 


In
the event the Borrower changes it corporate structure to a corporation than all references in this Note to units and membership
units shall be deemed to mean to shares.


 


The
Borrower shall provide to the Holder in writing from time to time promptly upon request a calculation of the then number of Conversion
Units in a format in in detail reasonably satisfactory to the Holder, provided that any error in such calculation by the Borrower
shall not limit or otherwise affect the obligations of the Borrower or any endorser or guarantor of this Note.


 


To
convert this Note, the Holder hereof shall deliver written notice thereof, substantially in the form of Exhibit B to this
Note, with appropriate insertions (the “Conversion Notice”), to the Borrower at its address as set forth herein.
The date upon which the conversion shall be effective (the “Conversion Date”) shall be deemed to be the date
set forth in the Conversion Notice.


 


The
Borrower shall deliver, or cause to be delivered, a certificate or certificates representing the Conversion Units, registered
in the name of the Holder, to the address specified in the Conversion Notice, within five (5) business days after the Conversion
Date. The Holder shall be deemed to be the holder of record of the Conversion Units for all purposes as of the Conversion Date.


 


Section
1.04 Reservation of Borrower Securities. The Borrower shall reserve and keep available solely for the purpose of conversion
of this Note that number of Borrower Securities to which this Note is convertible from time to time.


 


Section
1.05 Absolute Obligation/Ranking. Except as expressly provided herein, no provision of this Note shall alter or impair the
obligation of the Borrower, which is absolute and unconditional, to pay the unpaid principal of this Note and accrued but unpaid
interest thereon, at the time, place and rate, and in the coin or currency, herein prescribed. This Note is a direct debt obligation
of the Borrower.

	 	(c)
    	a
    default shall occur and be continuing under the Security Agreement after any time provided therein for curing the same shall
