CONVERTIBLE
PROMISSORY NOTE


 


FOR
VALUE RECEIVED, pursuant to the terms and conditions of this Convertible Promissory Note (this “Note”), Credex Corporation,
a Florida corporation (the “Company”), hereby promises to pay to the order of Robert S. Castanza (the “Holder”),
on October 31, 2022 or earlier as required pursuant to the terms herein (as applicable, the “Maturity Date”), the sum of
$70,000.00 (the “Principal Amount”), and to pay interest on the outstanding Principal Amount at the rate of twelve
percent (12%) per annum, simple interest, in each case to the extent that this Note and the Principal Amount and any accrued interest
hereunder (the “Indebtedness”) has not been converted into Conversion Shares (as defined below) prior to the Maturity Date.
Interest shall commence accruing on the date hereof (the “Issue Date”), computed on the basis of a 365-day year and the actual
number of days elapsed, and shall be payable as set forth herein.


 


This
Note is entered into pursuant to a Note Purchase Agreement by and between the Company and the Holder dated as of the Issue Date (the
“Agreement”) and is subject to the terms and conditions thereof.


 


This
Note is not a certificate of deposit or similar obligation of, and is not guaranteed or insured by, any depository institution, the Federal
Deposit Insurance Corporation, the Securities Holder Protection Corporation or any other governmental or private fund or entity.


 


The
following terms shall apply to this Note:


 


Section
1. Definitions. Defined terms used herein without definition have the meanings given them in the Agreement.


 


Section
2. Interest; Late Fees; Prepayment.


 


(a)
To the extent not converted to Conversion Shares (as defined below) prior to the Maturity Date, the Principal Amount and accrued and
unpaid interest shall be due and payable in full on the Maturity Date or such earlier date as set forth herein. No payments of the Principal
Amount or interest herein shall be required prior to the Maturity Date other than as specifically set forth herein.


 


(b)
The Company may prepay all or any portion of the Principal Amount and any accrued and unpaid interest at any time without penalty.


 




    	1



     


    

 


(c)
Interest on this Note shall accrue on a simple interest, non-compounded basis, and shall be added to the Principal Amount on the Maturity
Date or such earlier date as the Indebtedness may be paid hereunder or may be due hereunder pursuant to the terms herein, at which time
all Indebtedness shall be due and payable, unless earlier converted into Conversion Shares. In the event that any amount due hereunder
is not paid as and when due, such amounts shall accrue interest at the rate of 12% per year, simple interest, non-compounding, until
paid.


 


(d)
Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day.


 


Section
3. Conversion.


 


(a)
Conversion Right. Subject to the terms and conditions herein, the Holder shall have the right at any time on or after October
26, 2022 and ending on the full repayment of all Indebtedness (the “Conversion Period), to convert all or any part of the Indebtedness
into fully paid and non-assessable shares of Common Stock, or any shares of capital stock or other securities of the Company into which
such Common Stock shall hereafter be changed or reclassified (as applicable, the “Conversion Shares”) at the Conversion Price
as defined and as the same may be adjusted pursuant to Section 3(b) (a “Conversion”); provided, however, that in no event
shall the Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon conversion of which the
sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock
which may be deemed beneficially owned through the ownership of the unconverted portion of the Note or the unexercised or unconverted
portion of any other security of the Company subject to a limitation on conversion or exercise analogous to the limitations contained
herein) and (2) the number of shares of Common Stock issuable upon the conversion of the portion of this Note with respect to which the
determination of this proviso is being made, would result in beneficial ownership by the Holder and its affiliates of more than 9.99%
of the outstanding shares of Common Stock. For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall
be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and
Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso, provided, further, however, that the limitations
on conversion may be waived by the Holder upon, at the election of the Holder, not less than 61 days’ prior notice to the Company,
and the provisions of the conversion limitation shall continue to apply until such 61st day (or such later date, as determined
by the Holder, as may be specified in such notice of waiver). The number of Conversion Shares to be issued upon each conversion of this
Note shall be determined by dividing the Indebtedness by the applicable Conversion Price then in effect on the date specified in the
notice of conversion, in the form attached hereto as Exhibit A (the “Notice of Conversion”), delivered to the Company by
the Holder in accordance with the provisions herein.


 


(b)
Conversion Price; Adjustment.


 


	 	(i)	The conversion price (the “Conversion Price”) shall mean $1.20, subject to adjustment as set forth herein.
	 	 	 
	 	(ii)	

The Conversion Price
shall be subject to equitable adjustments for stock splits, stock dividends, combinations, recapitalization, reclassifications, extraordinary
distributions and similar events by the Company relating to the Common Stock that occur on or after the Issue Date. By way of example
and not limitation, in the event of forward split of the Common Stock following the Issue Date in which each share of Common Stock is
converted into two shares of Common Stock, the Conversion Price shall be reduced by 50%, and in the event of a reverse split of the Common
Stock following the Issue Date in which each two shares of Common Stock are converted into one share of Common Stock, the Conversion Price
shall be increased by 100%.

(c)
Mechanics of Conversion. Subject to the provisions of this Section 3, this Note may be converted by the Holder in whole or in
part at any time from time to time during the Conversion Period by (A) submitting to the Company a Notice of Conversion (by facsimile,
e-mail or other reasonable means of communication dispatched prior to 6:00 p.m., New York, New York time) and (B) subject to Section
3(c), surrendering this Note at the principal office of the Company. The conversion shall be effective as of the date of delivery of
the Notice of Conversion by the time as set forth above (the “Conversion Date”), provided that if the Notice of Conversion
is not delivered by such time then the Conversion Date shall be the next Business Day and the Notice of Conversion shall be deemed automatically
updated accordingly.


 


(d)
Surrender of Note Upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in
accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless the entire
unpaid amount of Indebtedness is so converted. The Holder and the Company shall maintain records showing the amount of Indebtedness so
converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so
as not to require physical surrender of this Note upon each such conversion. In the event of any dispute or discrepancy, such records
of the Company shall, prima facie, be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing,
if any portion of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders
this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note of like tenor,
registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the
remaining unpaid Indebtedness of this Note. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount of this
Note represented by this Note may be less than the amount stated on the face hereof.


 


(e)
Payment of Taxes. The Company shall not be required to pay any tax which may be payable in respect of any transfer involved in
the issue and delivery of Conversion Shares or other securities or property on conversion of this Note in a name other than that of the
Holder (or in street name), and the Company shall not be required to issue or deliver any such Conversion Shares or other securities
or property unless and until the person or persons (other than the Holder or the custodian in whose street name such shares are to be
held for the Holder’s account) requesting the issuance thereof shall have paid to the Company the amount of any such tax or shall
have established to the satisfaction of the Company that such tax has been paid.


 


(f)
Delivery of Common Stock Upon Conversion. Upon receipt by the Company from the Holder of the Notice of Conversion meeting the
requirements for conversion as provided in this Section 3, the Company shall issue and deliver or cause to be issued and delivered to
or upon the order of the Holder certificates for the Conversion Shares issuable upon such conversion within three (3) Business Days after
such receipt (and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of this Note) in accordance
with the terms hereof and the Agreement. Upon receipt by the Company of a Notice of Conversion, the Holder shall be deemed to be the
holder of record of the Conversion Shares issuable upon such conversion, the outstanding principal amount and the amount of accrued and
unpaid interest on this Note shall be reduced to reflect such conversion, and, unless the Company defaults on its obligations under this
Section 3, all rights with respect to the portion of this Note being so converted shall forthwith terminate except the right to receive
the Conversion Shares or other securities, cash or other assets, as herein provided, on such conversion. If the Holder shall have given
a Notice of Conversion as provided herein, the Company’s obligation to issue and deliver the certificates (subject to the provisions
of Section 3(g)) for Conversion Shares shall be absolute and unconditional, irrespective of the absence of any action by the Holder to
enforce the same, any waiver or consent with respect to any provision thereof, the recovery of any judgment against any person or any
action to enforce the same, any failure or delay in the enforcement of any other obligation of the Company to the holder of record, or
any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation to the
Company, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection
with such conversion.


 




    	3



     


    

 


(g)
Delivery of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the Conversion Shares
issuable upon conversion, provided the Company is participating in the Depository Trust Company (“DTC”) Fast Automated Securities
Transfer (“FAST”) program, upon request of the Holder and its compliance with the provisions contained in this Section 3,
the Company shall use its reasonable efforts to cause its transfer agent to electronically transmit the Conversion Shares issuable upon
conversion to the Holder by crediting the account of Holder’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission
system.


 


(h)
Adjustment Due to Merger, Consolidation, Etc. If, at any time when this Note is issued and outstanding and prior to full conversion
of this Note, there shall be any merger, consolidation, or an exchange of shares, recapitalization or reorganization pursuant to a merger
or consolidation, or other similar event, as a result of which shares of Common Stock of the Company shall be changed into the same or
a different number of shares of another class or classes of stock or securities of the Company or another entity, or in case of any sale
or conveyance of all or substantially all of the assets or more than 50% of the total outstanding shares of the Company other than in
connection with a plan of complete liquidation of the Company, then the Holder of this Note shall thereafter have the right to receive
upon conversion of this Note, upon the basis and upon the terms and conditions specified herein and in lieu of the Conversion Shares
immediately theretofore issuable upon conversion, such stock, securities or assets which the Holder would have been entitled to receive
in such transaction had this Note been converted in full immediately prior to such transaction (without regard to any limitations on
conversion set forth herein), and in any such case appropriate provisions shall be made with respect to the rights and interests of the
Holder of this Note to the end that the provisions hereof (including, without limitation, provisions for adjustment of the Conversion
Price and of the number of shares issuable upon conversion of the Note) shall thereafter be applicable, as nearly as may be practicable
in relation to any securities or assets thereafter deliverable upon the conversion hereof.


 


(i)
Status as Shareholder. Subject to the terms and conditions herein, upon submission of a Notice of Conversion by the Holder, (i)
this Note shall be deemed converted into Conversion Shares and (ii) the Holder’s rights as the holder of this Note shall cease
and terminate, excepting only the right to receive the Conversion Shares as set out herein and to any remedies provided herein or otherwise
available at law or in equity to such Holder because of a failure by the Company to comply with the terms of this Note.


 


Section
4. Events of Default.


 


(a)
The Holder may elect to declare an “Event of Default” if any of the following conditions or events shall occur and be continuing:


 


	 	(i)	the

    due and payable, and any such failure is not cured within three Business Days of written notice thereof by Holder;


 




    	4

    failure is not cured within three Business Days of written notice thereof by Holder;
	 	 	 
	 	(iii)	the
    Company shall (i) apply for or consent to the appointment of, or the taking of possession by, a receiver, custodian, trustee or liquidator;
    (ii) make a general assignment for the benefit of the Company’s creditors; or (iii) commence a voluntary case under the U.S.
    Bankruptcy Code as now and hereafter in effect, or any successor statute; or
	 	 	 
	 	(iv)	a
    proceeding or case shall be commenced, without the application or consent of the Company, in any court of competent jurisdiction,
    seeking (1) liquidation, reorganization or other relief with respect to it or its assets or the composition or readjustment of its
    debts, or (2) the appointment of a trustee, receiver, custodian, liquidator or the like of any substantial part of its assets, and,
    in each case, such proceedings or case shall continue undismissed, or an order, judgment or decree approving or ordering any of the
    foregoing shall be entered and continue unstayed and in effect, for a period of 60 days, if in the United States, or 90 days, if
    outside of the United States; or an order for relief against the Company shall be entered in an involuntary case under any bankruptcy,
    insolvency, composition, readjustment of debt, liquidation of assets or similar Law of any jurisdiction.


 


(b)
Consequences of Events of Default. If an Event of Default has occurred and is continuing (i) the Holder may, by notice to the
Company, declare all or any portion of the then outstanding principal amount of the Note, together with all accrued and unpaid interest
thereon, due and payable, and the Note shall thereupon become, immediately due and payable in cash and (ii) the Holder shall have the
right to pursue any other remedies that the Holder may have under applicable Law.
