SECOND AMENDED AND RESTATED

DISCRETIONARY CONVERTIBLE NON-REVOLVING LINE OF CREDIT DEMAND NOTE

FOR VALUE RECEIVED, and intending to be legally bound hereby, KEYSTAR CORP, a Nevada corporation (the "Maker"), hereby promises to pay ON DEMAND to the order of EXCEL FAMILY PARTNERS, LLLP, a Florida limited liability limited partnership (the "Lender"), the lesser of (i) the principal sum of Four Million Dollars ($4,000,000.00) (the "Loan Amount") or (ii) the aggregate unpaid principal balance of the Non-Revolving Credit Loans (as hereinafter defined) made by the Lender to the Maker from time to time, as may be evidenced by inscriptions made on Schedule 1 hereto, or as may be entered in a loan account on the Lender's books and records, or both (together will all extensions, renewals, refinancing or refundings in whole or in part, as amended, modified or supplemented from time to time, this "Note"), together with interest thereon at the rate or rates specified herein, as follows:

1.Non-Revolving Credit Loan Facility. 

(a)The Non-Revolving Credit Loans.  Subject to the terms and conditions hereof and relying upon the representations and warranties set forth in this Note, the Lender has made a loan (each, a "Non-Revolving Credit Loan" and collectively, the "Non-Revolving Credit Loans") to the Maker at any time or from time to time in an aggregate principal amount which will not exceed the Loan Amount. 

(b)Nature of the Non-Revolving Credit Loans.  Upon repayment of any amount of principal or interest of the Non-Revolving Credit Loans by the Maker, the Maker may not reborrow under this Note. 

(c)Making the Non-Revolving Credit Loans.  Subject to the terms and conditions set forth in this Note, and provided that the Maker has satisfied all applicable conditions specified herein, the Lender, in its sole and absolute discretion, will make the Non-Revolving Credit Loans to the Maker. 

(d)DISCRETIONARY ADVANCES.  THIS NOTE DOES NOT CONSTITUTE A COMMITTED LINE OF CREDIT.  NON-REVOLVING CREDIT LOANS UNDER THIS NOTE, IF ANY, SHALL BE MADE BY THE LENDER IN ITS SOLE AND ABSOLUTE DISCRETION.  NOTHING CONTAINED IN THIS NOTE SHALL BE CONSTRUED TO OBLIGATE THE LENDER TO MAKE ANY NON-REVOLVING CREDIT LOAN IN ANY AMOUNT AND THE LENDER SHALL HAVE THE RIGHT TO REFUSE TO MAKE ANY NON-REVOLVING CREDIT LOAN AT ANY TIME WITHOUT PRIOR NOTICE TO THE MAKER. 

(e)Maximum Principal Balance of Non-Revolving Credit Loans.  The aggregate principal amount of the Non-Revolving Credit Loans outstanding will not at any time exceed the Loan Amount.  The Maker agrees that if at any time the aggregate principal amount of the Non-Revolving Credit Loans outstanding exceeds the Loan Amount (the "Excess Amount"), the Maker will promptly pay to the Lender such Excess Amount. 

(f)Use of Proceeds.  Non-Revolving Credit Loans may be subject to restricted uses from time to time, at the sole and absolute discretion of the Lender.  Lender may provide written instructions (instructions via email are permitted) to Maker regarding restrictions on the use of the Non-Revolving Credit Loans.  Absent such instructions from the Lender, the Maker may use the Non-Revolving Credit Loans for (i) general company purposes and/or (ii) any other use approved in writing by the Lender, in its sole and absolute discretion. 

- 1 -

(g)Outstanding Principal Balance of Non-Revolving Credit Loans.  All advances of principal made on this Note may be inscribed by the Lender on Schedule 1 hereto in the Lender's discretion or entered on the Lender's books and records.  Each inscription or entry shall be prima facie evidence of the facts so set forth.  No failure by the Lender to make, and no error by the Lender in making, any inscription on Schedule 1 shall affect the Maker’s obligation to repay the full principal amount advanced by the Lender to or for the account of the Maker, or the Maker’s obligation to pay interest thereon at the agreed upon rate.   

2.Interest Rate. 

(a)Interest.  The interest which accrued under the Existing Note (as hereinafter defined) as of December 31, 2022 (the "Converted Interest"), in the amount evidenced by inscriptions made on Schedule 1 hereto, was converted to principal as of December 31, 2022.  Subject to the terms and conditions of this Note, the aggregate outstanding principal balance of the Non-Revolving Credit Loans, including the Converted Interest, will bear interest as of January 1, 2023 at a fixed rate per annum equal to 15.0% (the "Fixed Rate").  Interest on Non-Revolving Credit Loans, unpaid fees and other sums payable hereunder will be computed on the basis of a year of 365 days and paid for the actual number of days elapsed. 

(b)Interest After Default.  If the Maker (i) fails to comply with any provision hereunder, including, but not limited to, failing to immediately pay all amounts due hereunder to the Lender after demand thereof is made, or (ii) becomes subject to any event described in Section 8 hereof, at the option of the Lender, the unpaid principal amount of the Non-Revolving Credit Loans or any portion thereof, accrued interest thereon, any fees or any other sums payable hereunder will thereafter until paid in full bear interest at a rate per annum equal to the Fixed Rate plus 2.00%. 

3.Description of Payments. 

(a)Payments of Interest.  Beginning on March 1, 2023, and continuing on the first day of each month thereafter to the date on which Lender demands payment of this Note, the Maker will pay to the Lender interest, in arrears, on the aggregate outstanding principal balance of the Non-Revolving Credit Loans at the Fixed Rate. 

(b)Payments of Principal.  If not sooner paid, the entire principal balance of all outstanding Non-Revolving Credit Loans, together with all unpaid accrued interest thereon, and all other sums and costs owed to the Lender by the Maker with respect to the Non-Revolving Credit Loans will be immediately due and payable ON DEMAND, without presentment, protest or notice or further demand of any kind, all of which are hereby waived and an action therefore shall accrue immediately. 

(c)Optional Prepayments.  The Maker will have the right to prepay the Non-Revolving Credit Loans, in whole or in part, at any time; provided, however, the Maker must (i) provide the Lender prior written notice of the Maker's intention to make such prepayment and (ii) pay to the Lender all interest accrued on the outstanding principal balance of the Non-Revolving Credit Loans to the date of such prepayment and all other fees, costs and charges required to be paid by the Maker to and for the benefit of the Lender.   

(d)Payments.  All payments (and to the extent the Maker determines to make any prepayments) to be made in respect of principal, interest, fees or other amounts due from the Maker under this Note will be payable on or before 5:00 p.m. (Eastern Time) on the day when due without presentment, further demand, protest or notice of any kind, all of which are hereby expressly waived.  Payments made after 5:00 p.m. (Eastern Time) shall be deemed to be made on the next Business Day.  All such payments must be made to the Lender at its designated address in lawful money of the United States of America in  

- 2 -

immediately available funds without setoff, counterclaim or other deduction of any nature.  Subject to the terms and conditions of this Note, all such payments will be applied at the option of the Lender to accrued and unpaid interest, outstanding principal and other sums due under this Note in such order as the Lender may elect. All such payments will be made absolutely net of, without deduction or offset, and altogether free and clear of any and all present and future taxes, levies, deductions, charges and withholdings and all liabilities with respect thereto, excluding income taxes imposed on the Lender under the Laws (as hereinafter defined) of the United States or any state or political subdivision thereof.  

4.Conversion. 

(a)Right to Convert.  The Lender may, at its sole option, convert all or any portion of the Debt (as hereinafter defined) into fully paid and non-assessable shares of common stock of the Maker (the “Shares”) at a conversion price in an amount equal to the product of the Lowest Recent Price (as hereinafter defined) multiplied by 80% (such amount is referred to as the “Conversion Price”).  The number of Shares to be issued upon each conversion of the Debt shall be determined by dividing the Conversion Amount (as hereinafter defined) by the applicable Conversion Price then in effect on the date specified in a notice of conversion (“Conversion Notice”) given by Lender, delivered to Maker by Lender on such conversion date (the “Conversion Date”).  Promptly after receipt of a Conversion Notice, the Maker shall provide evidence in form and substance acceptable to the Lender in its sole discretion, that the conversion of such Debt into Shares has occurred. 

(b) Adjustments for Reclassification and Reorganization.  In case of any reclassification, capital reorganization, or other change of outstanding Shares, or in case of any consolidation or merger of the Maker with or into another entity (other than a consolidation or merger in which the Maker is the continuing company and which does not result in any reclassification, capital reorganization, or other change of outstanding Shares), the Maker shall cause effective provision to be made so that the Lender shall have the right thereafter, by converting the Debt, to receive upon such conversion the kind and number of shares of stock or other securities or property (including cash) receivable upon such reclassification, capital reorganization, or other change, consolidation or merger by a holder of the number of Shares that could have been received upon conversion of the Debt immediately prior to such reclassification, capital reorganization, or other change, consolidation or merger. Any such provision shall include provision for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 4. The foregoing provisions shall similarly apply to successive reclassifications, capital reorganizations, and other changes of outstanding shares and to successive consolidations or mergers. If the consideration received by the holders of Shares is other than cash, the value shall be as determined by the board of directors of the Maker acting in good faith. 

(c)Adjustment for Stock Splits.  If and whenever the Maker shall declare or cause a stock split, a stock combination, or a reverse stock split of the Shares, the number of Shares into which the Debt may be converted and the Conversion Price shall be proportionately adjusted in the manner determined by the Maker’s board of directors acting in good faith. The number of Shares into which the Debt may be converted, as so adjusted, shall be rounded down to the nearest whole number and the Conversion Price shall be rounded to the nearest cent. 

5.Representations and Warranties.  The Maker represents and warrants to the Lender that: (i) it is duly organized, validly existing and in good standing under the Laws of the jurisdiction of its formation, and is in good standing and registered to conduct business in all other jurisdictions in which any such  failure would materially and adversely affect its ability to perform its obligations hereunder, (ii) the Maker has full power, authority and legal right to enter into this Note and the other Loan Documents and to perform all of its respective obligations hereunder and thereunder and (iii) this Note and the other Loan Documents have been duly executed and delivered by the Maker, and this Note and the other Loan  

- 3 -

Documents constitute the legal, valid and binding obligation of the Maker enforceable in accordance with their terms, except as such enforceability may be limited by any applicable bankruptcy, insolvency, moratorium or similar Laws affecting creditors' rights generally.

6.Affirmative Covenants.  The Maker covenants and agrees with the Lender as follows: 

(a)Notice of Breach.  Promptly upon becoming aware of any failure of the Maker to comply with any provision hereunder, the Maker will give the Lender notice thereof, together with a written statement signed on behalf of the Maker setting forth the details of such failure and any action taken or contemplated to be taken by the Maker with respect thereto. 

(b)Further Information.  The Maker will promptly furnish, or will cause to be promptly furnished, to the Lender such other information, and in such form, as the Lender may reasonably request from time to time. 

(c)Further Assurances.  The Maker, at the Maker's own cost and expense, will cause to be promptly and duly taken, executed, acknowledged and delivered all such further acts, documents and assurances as the Lender may reasonably request from time to time in order to carry out the intent and purposes of this Note and the transactions contemplated by this Note. 

(d)Other Conditions.  Concurrently herewith, the Maker will deliver such other documents and satisfy such other conditions as may be reasonably required to be delivered or satisfied by the terms of this Note and/or any other Loan Document. 

7.Negative Covenants.  The Maker covenants to the Lender as follows: 

(a)Liens.  The Maker will not at any time create, incur, assume or permit to exist any Lien on or any of its assets without the prior written consent of Lender, which consent may be given or withheld in Lender’s sole discretion. 

(b)Indebtedness.  The Maker will not, at any time, create, incur, assume or suffer to exist any Indebtedness (as hereinafter defined) without the Lender’s prior written consent, except: 

(i)Indebtedness under this Note or any other Loan Document or any other document, instrument or agreement between the Maker and the Lender; and 

(ii)current accounts payable, accrued expenses and other expenses arising out of transactions (other than borrowing) in the ordinary course of business. 

(c)Disposition of Assets.  Except as set forth in this Note and/or any other Loan Document, the Maker will not sell, convey, pledge, assign, abandon, transfer or dispose of, voluntarily or involuntarily, any of its assets without the Lender’s prior written consent. 

(d)Dividends and Distributions.  The Maker will not make, cause, permit or allow the payment of any dividends or distributions to any member of Maker without the Lender’s prior written consent.
