Jones. Blvd., Suite 6354, Las Vegas, Nevada 89107 or such other address as Holder may designate, in lawful money of the United States of America, up to a maximum principal amount of FOUR MILLION DOLLARS ($4,000,000.00) (“Maximum Principal Sum”), or so much thereof as may be actually advanced or readvanced and remains unpaid, together with interest from the date hereof at the rate of eighteen percent (18%) per annum (the “Interest Rate”) on the unpaid principal amount hereof, with principal and interest to be paid as follows:

1. Maturity Date; Monthly Payments. Beginning on April 1, 2023 and on the first (1st) day of each month thereafter until the amounts set forth herein and due hereunder have been repaid in full, Maker shall pay monthly interest payments based upon the then outstanding principal amount of the loan (“Monthly Payment”). On or before February 1, 2024 (“Maturity Date”), Maker shall pay to Holder the entire outstanding principal amount under this Revolving Line of Credit Promissory Note (“Note”) and all unpaid interest accrued thereon.

a. In addition to all other amounts due to Lender hereunder and under this Note, Borrower shall pay to Lender on the first day of each month, an availability fee equal to 5% per annum on the average daily unused available principal under this Note for the preceding month or portion thereof.

2. Initial Advance and Additional Advances and Requirements. Maker has requested an initial advance under this Note in the principal sum of $1,500,000.00 which will be funded upon closing (“Initial Advance”).

a. Additional advances under this Note (each an “Advance”) shall be made exclusively for the purpose of satisfying the monthly obligations (each an “Obligation”) of the Maker under the terms and conditions of the Forbearance Agreement and related agreements between Maker and Blue Sky Services LLC (“Blue Sky”). In connection with each Advance, Maker shall provide to Holder a statement of the total monthly Obligation to be paid to Blue Sky. Upon review and approval of each Obligation, in Holder’s sole discretion, Holder shall directly fund the Obligation to Blue Sky and the amount of the Advance shall be added to the outstanding principal balance of this Note.

3. Prepayment. Maker has the right to make payments of principal at any time before they are due. A payment of Principal only is known as a “Prepayment.” When Maker makes a Prepayment, Maker shall tell the Holder in writing that Maker is doing so. Maker may not designate a payment as a Prepayment if Maker has not made all the monthly payments due under the Note. Maker may make a full Prepayment or partial Prepayments without paying a Prepayment charge; provided however, the Holder shall use Maker’s Prepayments to reduce the amount of Principal that Maker owes under this Note. However, the Holder may apply Maker’s Prepayment to the accrued and unpaid interest on the Prepayment amount, before applying any Prepayment to reduce the Principal amount of the Note. If Maker makes a partial Prepayment, there will be no changes in the due date or in the amount of the monthly payment unless the Holder agrees in writing to those changes.

4. Origination Fees and Costs. The Principal Amount shall include (i) loan fees (“Loan Fees”) in the amount of Two Hundred Eighty Thousand Dollars ($280,000.00), and (ii) loan closing fees, title fees, construction control fees and legal fees incurred by Holder (including, without limitation, attorneys’ fees) in connection with closing, escrow and title costs (“Other Fees”) Net proceeds equal to the Principal Amount less the amounts payable pursuant to items (i) through (ii) above, which net proceeds shall be disbursed to Maker at the closing. Maker acknowledges and agrees the Loan Fees, Interest Reserve and Other Fees are neither a reduction of the Principal Amount nor a payment for interest and is deemed fully earned upon receipt by Holder.

5. Interest. Notwithstanding anything to the contrary contained herein, interest shall begin to accrue on the date of this Note. Interest shall be computed on the actual number of days elapsed (including the first day but excluding the last day) on the basis of a three hundred sixty (360) day year of twelve (12) thirty-day months compounded monthly. Maker shall pay all amounts due under this Note in lawful money of the United States of America and without set-off, deduction, demand or notice.

6. Application of Payments. Payments will be applied first to any costs and expenses (including reasonable attorneys’ fees) incurred by Holder in connection with the collection of amounts owing pursuant to this Note, next to payment of late charges and accrued interest, and then to reduction of principal, or as otherwise determined at Holder’s sole and absolute discretion. All payments shall be made to Holder at the above-specified address until receipt of notice from Holder to the contrary.

7. Late Charge. If Maker fails to make any payment hereunder on the date that such payment is due, then Maker shall, to the extent permitted by law, pay to Holder a late charge equal to five percent (5.0%) of the amount due. The assessment and acceptance of a late charge by the Holder shall not constitute a waiver of the Holder’s right to demand strict performance in accordance with the terms and conditions of this Note.

8. Default Rate. ALL AMOUNTS DUE HEREUNDER NOT PAID ON THE DATE WHEN DUE (WHETHER BY ACCELERATION OR OTHERWISE) SHALL BEAR INTEREST (PAYABLE ON DEMAND) AT THE INTEREST RATE OF 24% PER ANNUM (THE “DEFAULT RATE”) OR AT THE MAXIMUM RATE PERMITTED BYLAW IF SUCH MAXIMUM RATE IS LOWER, FROM SUCH DATE UNTIL PAID. Interest at the Default Rate shall accrue pre-judgment and post-judgment.
