Promissory Note, dated February 3, 2020, by Mountain Hawk East Development Company LLC in favor of Sandia Laboratory Federal Credit Union

Exhibit 10.2

PROMISSORY NOTE

PROMISE TO PAY. MOUNTAIN HAWK EAST DEVELOPMENT COMPANY LLC ("Borrower") promises to pay to Sandia Laboratory Federal Credit Union ("Lender"), or order, in lawful money of the United States of America, the principal amount of Three Million & 00/100 Dollars ($3,000,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance, calculated as described in the "INTEREST CALCULATION METHOD" paragraph using an interest rate of 4.500% per annum. Interest shall be calculated from the date of each advance until repayment of each advance. The interest rate may change under the terms and conditions of the "INTEREST AFTER DEFAULT" section.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on August 1, 2022. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning March 1, 2020, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any late charges; and then to any unpaid collection costs. Borrower will pay 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 a 365/365 basis; that is, by applying the ratio of the interest rate over the number of days in a year (365 for all years, including leap years), multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law. Except for the foregoing, Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. 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, and 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: Sandia Laboratory Federal Credit Union, Attn: Business Services, 3707 Juan Tabo Blvd. Albuquerque, NM 87111.

LATE CHARGE. If a payment is late 10 or more days, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment or $10.00, whichever is greater.

INTEREST AFTER DEFAULT. Upon the occurrence of an Event of Default, including failure to pay upon final maturity, the interest rate on this Note shall be increased by 5.000 percentage points. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.

DEFAULT. Each of the following shall constitute an event of default ("Event of Default") under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower's behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Death or Insolvency. The dissolution of Borrower (regardless of whether election to continue is made), any member withdraws from Borrower, or any other termination of Borrower's existence as a going business or the death of any member, the insolvency of Borrower the appointment of a receiver for any part of Borrower's property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrower's accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Adverse Change. A material adverse change occurs in Borrower's financial condition.

Right to Cure. As a condition precedent to an Event of Default, Lender will provide Borrower written notice and thereafter either: (a) fifteen (15) days to cure any monetary default; and (b) thirty (30) days to cure any non-monetary default or, if the non-monetary default is of the nature that cannot reasonably be cured within thirty (30) days, then Grantor shall initiate steps which Lender, in Lender’s sole discretion, deems sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.
