GREY CLOAK TECH INC.

CONVERTIBLE PROMISSORY NOTE

 

 

	$61,366.59	 	September 30, 2018

 

FOR VALUE RECEIVED, Grey
Cloak Tech Inc., a Nevada corporation, its assigns and successors (the “Company”), hereby promises to pay to
the order of William Bossung, or his assigns (the “Holder”), in immediately available funds, the total principal
sum of Sixty-One Thousand Three Hundred and Sixty-Six Dollars and fifty-nine cents ($61,366.59). The principal hereof and any unpaid
accrued interest thereon shall be due and payable on or before 5:00 p.m., Pacific Standard Time, on the date which is six
(6) months from the date hereof (the “Maturity Date”) (unless such payment date is accelerated as provided in
Section 7 hereof). Payment of all amounts due hereunder shall be made at the address of the Holder provided for in Section
8 hereof. Interest shall accrue at the rate of ten percent (10%) per annum on this Note from the date hereof and shall be paid
monthly to the Holder beginning on December 1, 2018.

 

1.                 
HISTORY OF THE LOAN. This Note is being delivered to Holder as consideration for money loaned and accrued
payables from the Holder to the Company.

 

2.                 
PREPAYMENT. The Company may at any time, up to 90 days, upon 30 days written notice to Holder, prepay all
or any part of the principal balance of this Note, at a prepayment price equal to One Hundred Percent (100%) of the then-outstanding
principal and interest, provided that concurrently with each such prepayment the Company shall pay accrued interest on the principal,
if any, so prepaid to the date of such prepayment. If after 90 days it’s the holder’s option. The 30 days written notice,
and the end of the 30-day period, shall be referred to herein as a “Prepayment Notice” and a “Prepayment
Date,” respectively. In the event that the Company sends a Prepayment Notice to Holder, Holder may elect prior to the Prepayment
Date to convert into common stock of the Company pursuant to Section 3 hereof, all or part of the amount of principal to be repaid
by the proposed prepayment instead of receiving such prepayment

 

3.                 
CONVERSION.

3.1       Conversion
Rights; Conversion Date; Conversion Price. The Holder shall have the right, at his option, at any time from and after the date
hereof, to convert the principal amount of this Note, or any portion of such principal amount, into that number of fully paid and
nonassessable shares of the Company’s common stock (the “Common Stock”) (as such shares shall then be
constituted) determined pursuant to this Section 3.1. The number of shares of Common Stock to be issued upon each conversion
of this Note shall be determined by dividing the Conversion Amount (as defined below) by the Conversion Price (as defined below). 

    Page 1 of 6

    

    

Each election will be noticed by
a Notice of Conversion, substantially in the form attached hereto as Exhibit A, delivered to the Company by Holder by
facsimile, or other reasonable means of communication, dispatched prior to 5:00 p.m., Pacific Standard Time and in accordance
with the terms of Section 8. The term “Conversion Amount” means, with respect to any conversion of this
Note, the sum of (1) the principal amount of this Note to be converted in such conversion, plus (2) accrued and unpaid
interest, if any, on such principal amount at the interest rates provided in this Note to the Conversion Date.

3.2       Conversion
Price. The conversion price (the “Conversion Price”) shall mean the lower of thirty percent (30%) of the
average of the closing Trading Price (as defined below) for the Common Stock during the three (3) Trading Day period ending on
the latest complete Trading Day prior to the Conversion Date or $.05 (five cents). “Trading
Price” means, for any security as of any date, the closing trading price on the Over-the-Counter Bulletin Board, Pink
Sheets electronic quotation system or applicable trading market (the “OTC”) as reported by a reliable reporting
service (“Reporting Service”) designated by the Holder (i.e. NASDAQ) or, if the OTC is not the principal trading
market for such security, the lowest trading price of such security on the principal securities exchange or trading market where
such security is listed or traded or, if no lowest trading price of such security is available in any of the foregoing manners,
the average of the lowest trading prices of any market makers for such security that are listed in the “pink sheets.”
“Trading Day” shall mean any day on which the Common Stock is tradable for any period on the stock exchange
on which the Borrower’s Common Stock is traded. In the event that shares of Borrower’s Common Stock are not deliverable
via DWAC following the conversion of any amount hereunder, a ten percent (10%) discount shall be factored into the Conversion Price
until this Note is no longer outstanding.

 

3.3Method of
Conversion.

 

(a)       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 principal amount of this Note is so converted.
Rather, records showing the principal amount converted (or otherwise repaid) and the date of such conversion or repayment shall
be maintained on a ledger substantially in the form of Annex I attached hereto (a copy of which shall be delivered to the
Company with each Notice of Conversion). It is specifically contemplated that the Company shall act as the calculation agent for
conversions and repayments. In the event of any dispute or discrepancies, such records maintained by the Company shall be controlling
and determinative in the absence of manifest error. The Holder and any assignee, by acceptance of this Note, acknowledge and agree
that, by reason of the provisions of this paragraph, following a conversion of a portion of this Note, the principal amount represented
by this Note will be the amount indicated on Annex I attached hereto (which may be less than the amount stated on the face
hereof).

 

(b)       Upon receipt by the Company of a Notice of Conversion, the Holder shall be deemed to be the holder
of record of the Common Stock issuable upon such conversion and 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

    Page 2 of 6

    

    

obligations under Section 7,
all rights with respect to the portion of this Note being so converted shall forthwith terminate except the right to receive the
Common Stock 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 for shares of Common
Stock 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 by the Holder 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. The date of receipt (including receipt via facsimile) of such Notice of Conversion shall be
the Conversion Date so long as it is received before 5:00 p.m., Pacific Standard Time, on such date.

 

4.                 
CONVERSION LIMITATION. Notwithstanding Section 3 above, the Holder may not convert any outstanding
amounts due under this Note if at the time of such conversion the amount of common stock issued for the conversion, when added
to other shares of Company common stock owned by the Holder or which can be acquired by Holder upon exercise or conversion of any
other instrument, would cause the Holder to own more than nine and nine-tenths percent (9.9%) of the Company’s outstanding
common stock. The restriction described in this paragraph may be revoked upon sixty-one (61) days prior notice from Holder to the
Company. For purposes of this Section, beneficial ownership shall be determined in accordance with Rule 13d-3 of the Exchange Act
and Regulations 13 D-G thereunder, except as otherwise provided in this Section.

 

5.                 
TRANSFERABILITY. This Note shall not be transferred, pledged, hypothecated, or assigned by either party without
the express written consent of the other Party. In the event any third party acquires a controlling interest in the Company or
acquires substantially all of the assets of the Company (a “Reorganization Event”), this Note will survive and
become an obligation of the party that acquires such controlling interest or assets. In the event of a Reorganization Event the
Company agrees to make the party that acquires such controlling interest or assets, aware of the terms of this Section and this
Note.

 

6.                 
RESERVATION AND LISTING OF SECURITIES. The Company shall at all times reserve and keep available out of its
authorized shares of common stock, solely for the purpose of issuance upon the conversion of this Note, such number of shares of
common stock as would be necessary to convert the entire amount due and owing under the terms of this Note if Holder elected to
convert said amount under Section 3 hereof.

 

7.                 
DEFAULT. The occurrence of any one of the following events shall constitute an Event of Default:

 

(a)       The
non-payment, when due, of any principal or interest pursuant to this Note;

 

    Page 3 of 6

    

    

(b)       The
material breach of any representation or warranty in this Note. In the event the Holder becomes aware of a breach of this Section
7(b), the Holder shall notify the Company in writing of such breach and the Company shall have five business days after notice
to cure such breach;

 

(c)       The
breach of any covenant or undertaking, not otherwise provided for in this Section 7;

 

(d)       The
commencement by the Company of any voluntary proceeding under any bankruptcy, reorganization, arrangement, insolvency, readjustment
of debt, receivership, dissolution, or liquidation law or statute of any jurisdiction, whether now or hereafter in effect; or the
adjudication of the Company as insolvent or bankrupt by a decree of a court of competent jurisdiction; or the petition or application
by the Company for, acquiescence in, or consent by the Company to, the appointment of any receiver or trustee for the Company or
for all or a substantial part of the property of the Company; or the assignment by the Company for the benefit of creditors; or
the written admission of the Company of its inability to pay its debts as they mature; or

 

(e)       The
commencement against the Company of any proceeding relating to the Company under any bankruptcy, reorganization, arrangement, insolvency,
adjustment of debt, receivership, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect,
provided, however, that the commencement of such a proceeding shall not constitute an Event of Default unless the Company consents
to the same or admits in writing the material allegations of same, or said proceeding shall remain undismissed for 20 days; or
the issuance of any order, judgment or decree for the appointment of a receiver or trustee for the Company or for all or a substantial
part of the property of the Company, which order, judgment or decree remains undismissed for 20 days; or a warrant of attachment,
execution, or similar process shall be issued against any substantial part of the property of the Company.

 

Upon the occurrence of
any Default or Event of Default, the Holder, may, by written notice to the Company, declare all or any portion of the unpaid principal
amount due to Holder, together with all accrued interest thereon, immediately due and payable, in which event it shall immediately
be and become due and payable, provided that upon the occurrence of an Event of Default as set forth in paragraph (d) or paragraph
(e) hereof, all or any portion of the unpaid principal amount due to Holder, together with all accrued interest thereon, shall
immediately become due and payable without any such notice.
