The interest rate may change under the terms and conditions of the "POST MATURITY RATE' section. (This Amended and Extended Promissory Note ("Amended Note") and the Convertible Promissory Note dated September 10, 2021 by an between Stemtech Corporation, a Delaware corporation, Stemtech HealthSciences Corp, a Florida corporation, and Globe Net Wireless Corporation, a Nevada corporation and Lender ("Original Note") are collectively referred to herein as the"Note".)

LOAN PURPOSE: The Original Note was to provide financing for the Borrower's working capital needs. This Amended Note, being an accommodation by the Lender to Borrower, is made for the purpose of extending the Original Note's maturity date, to address Original Note covenant breaches by Borrower, and to modify the Original Note's repayment terms. For purpose of clarity, the Amended Note is an (i) extension and modification of the Original Note, (ii) the Borrower and Lender intend that all other Original Note terms not addressed herein shall remain unchanged, and (iii) any and all security agreements existing between the Lender, Borrower, and/or Guarantor related to, directly or indirectly, the Original Note, continue to be in place, effective and enforceable for all purposes stated therein.

The Lender and Borrower agree that as of the date of this Amended Note, May 1, 2023, the outstanding principal and interest balance owing on the Original Note was:

As a condition precedent to this amendment and modification, the Lender requires the Borrower to pay at closing, the accrued unpaid interest owing in the amount of $222,555.56.

PAYMENT OF PRINCIPAL AND INTEREST.

The Original Note repayment terms are hereby amended to be repaid on the following terms and conditions:

On demand. If no demand, then Borrower will repay the principal, interest, and fees, if any, owing on the loan evidenced by this Note as follows:

Unless otherwise agreed or required by applicable law, payments will be applied first to any fees or late charges, then to any unpaid collection costs, then to any accrued unpaid interest, and then to principal. Borrower will make all payments to Lender at Lender's address shown above or at such other place as Lender may designate in writing.

INTEREST CALCULATION METHOD. Interest on this Note is computed on an actual day, 360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding, unless such calculation would result in a usurious rate, In which case interest shall be calculated on a per diem basis of a year of 365 or 366 days, as the case may be. All interest payable under this Note is computed using this method.

LATE PAYMENT FEES. If a payment is 10 or more days late, Borrower will pay a delinquency charge in an amount equal to 5.0% of the amount of the delinquent payment. This amount is stipulated by Borrower to be reasonable in order to compensate Lender for its additional costs incurred as a result of having to attend to such delinquency. This late charge should be paid only once, but promptly, as to each respective late payment. It is further agreed that the imposition of any such late payment fee shall in no way prejudice or limit Lender's right or remedies against Borrower under the Note, Guaranty, Security Agreement or any other loan document related to the Note.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Prepayment in full shall consist of payment of the remaining unpaid principal balance together with all accrued and unpaid interest and all other amounts, costs and expenses for which Borrower is responsible under this Note or any other agreement with Lender pertaining to this Note/loan, and in no event will Borrower ever be required to pay any unearned interest. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments under the payment schedule. Rather, early payments will reduce the principal balance due in the inverse order of maturity. Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, security agreement and/or guaranty(ies), and the Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes "payment In full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to:

However, this relinquishment does not apply to any previous redemptions the Lender may have already exercised or any rights the Lender may have in previously issued warrants of the Borrower.

False Statements.

Cure Provisions.

SUCCESSOR INTERESTS. The terms of this Note shall be binding upon Borrower, and upon Borrower's heirs, personal representatives, successors and assigns, and shall inure to the benefit of Lender and its successors and assigns.

GENERAL PROVISIONS. NOTICE: Under no circumstances (and notwithstanding any other provisions of this Note) shall the interest charged, collected, or contracted for on this Note exceed the maximum rate permitted by law. The term "maximum rate permitted by law" as used in this Note means the greater of (a) the m ximum rate of interest permitted under federal or other law applicable to the indebtedness evidenced by this Note, or (b) the higher, as of the date of this Note, of the "Weekly Ceiling" or the "Quarterly Ceiling" as referred to in Sections 303.002, 303.003 and 303.006 of the Texas Finance Code. If any part of this Note cannot be enforced, this fact will not affect the rest of the Note. Borrower does not agree or intend to pay, and Lender does not agree or intend to contract for, charge, collect, take, reserve or receive (collectively referred to herein as "charge or collect"), any amount in the nature of interest or in the nature of a fee for this loan, which would in any way or event (including demand, prepayment, or acceleration) cause Lender to charge or collect more for this loan than the maximum Lender would be permitted to charge or collect by federal law or the law of the State of Texas (as applicable). Any such excess interest or unauthorized fee shall, instead of anything stated to the contrary, be applied first to reduce the principal balance of this loan, and when the principal has been paid in full, be refunded to Borrower. The right to accelerate maturity of sums due under this Note does not include the right to accelerate any interest which has not otherwise accrued on the date of such acceleration, and Lender does not intend to charge or collect any unearned interest in the event of acceleration. All sums paid or agreed to be paid to Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of the loan evidenced by this Note until payment in full so that the rate or amount of interest on account of the loan evidenced hereby does not exceed the applicable usury ceiling. Lender may delay or forgo enforcing any of its rights or remedies under this Note without losing them. Each Borrower understands and agrees that, with or without notice to Borrower, Lender may with respect to any other Borrower (a) make one or more additional secured or unsecured loans or otherwise extend additional credit; (b) alter, compromise, renew, extend, accelerate, or otherwise change one or more times the time for payment or other terms of any indebtedness, including Increases and decreases of the rate of interest on the indebtedness; (c) exchange, enforce, waive, subordinate, fail or decide not to perfect, and release any security, with or without the substitution of new collateral; (d) apply such security and direct the order or manner of sale thereof, including without limitation, any non-judicial sale permitted by the terms of the controlling security agreements, as Lender in its discretion may determine; (e) release, substitute, agree not to sue, or deal with any one or more of

Borrower's sureties, endorsers, or other guarantors on any terms or in any manner Lender may choose; and (f) determine how, when and what application of payments and credits shall be made on any other indebtedness owing by such other Borrower. Borrower and any other person who signs, guarantees or endorses this Note, to the extent allowed by law, waive presentment, demand for payment, notice of dishonor, notice of intent to accelerate the maturity of this Note, and notice of acceleration of the maturity of this Note. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note, whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender may renew or extend (repeatedly and for any length of time) this loan or release any party or guarantor or collateral; or impair, fail to realize upon or perfect Lender's security interest in the collateral without the consent of or notice to anyone. All such parties also agree that Lender may modify this loan without the consent of or notice to anyone other than the party with whom the modification is made.
