PROMISSORY NOTE

For value received, DRAGONFLY ENERGY HOLDINGS CORP., a Delaware corporation (the “Company”), unconditionally promises to pay to Brian Nelson, an individual (the “Investor”), the principal sum of One Million Dollars ($1,000,000.00), or such lesser amount as shall then equal the outstanding principal amount hereunder, together with all other fees, charges or expenses set forth herein.

1. Maturity. The outstanding principal and all accrued but unpaid fees, charges and expenses under this Note (collectively, the “Note Balance”) shall be due and payable in full in cash on April 1, 2023 (the “Maturity Date”) or, if earlier, the date of acceleration of the obligations hereunder pursuant to Section 5(c).

2. Loan Fee Payment and Interest. Upon execution of this Note and funding of the original principal sum, a payment of One Hundred Thousand Dollars ($100,000.00) (the “Loan Fee”) shall be fully earned as of the date hereof but due and payable in full in cash on April 4, 2023, or, if earlier, the date of acceleration of the obligations hereunder pursuant to Section 5(c) (the “Loan Fee Payment Date”). If the Loan Fee is not received in full by the Loan Fee Payment Date, a penalty of an additional One Hundred Thousand Dollars ($100,000.00) (the “First Penalty Fee”) shall immediately accrue in full as of April 5, 2023, and so long as the principal, Loan Fee and First Penalty Fee remain unpaid thereafter, an additional One Hundred Thousand Dollars ($100,000.00) shall immediately accrue in full as of May 3, 2023. If the Note Balance has not been fully repaid by June 1, 2023, the Company will repay the Note Balance with any combination of (i) cash, and (ii) the granting of common stock of the Company to the Investor, in an amount equal to the Note Balance as of the date thereof; provided, however, if the Company opts to pay in whole or in part pursuant to clause (ii) herein, the amount payable shall be at a price per share equal to the Consolidated Closing Bid Price of the common stock as reported by Nasdaq on the date immediately prior to payment; provided, however that such price shall not be less than $4.18.

3. Payments.

(a) Payments Generally. All payments shall be made in lawful money of the United States of America at such place as the Investor hereof may from time to time designate in writing to the Company. Any amount that is repaid or prepaid may not be re-borrowed. Any amounts due and payable hereunder will be sent by wire transfer in accordance with instructions delivered to the Company by the Investor. If any payment to be made by Borrower hereunder becomes due on a day which is not a Business Day (as defined below), such payment must be made on the next succeeding Business Day.

(b) Optional Prepayments. The Company may prepay all or any portion of the outstanding principal of the Note at any time without premium or penalty.

(c) Mandatory Prepayment. Within one Business Day after the occurrence of a Change of Control (as defined below), the Company shall repay all outstanding obligations under the Note in full.

4. Interest Rate Limitation. Notwithstanding anything to the contrary contained in this Note, the interest paid or agreed to be paid under this Note shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum Rate”). If the Investor shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal remaining owed under this Note or, if it exceeds such unpaid principal, refunded to the Company. In determining whether the interest contracted for, charged, or received by the Investor exceeds the Maximum Rate, the Investor may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of this Note.

5. Events of Default.

(a) The occurrence of any of the following shall constitute an “Event of Default” under this Note:

(i) the Company shall fail to observe or perform any other material covenant, obligation, condition or agreement contained in this Note, including the failure to pay any amounts under this Note when due;

(ii) the Company files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law for the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any corporate action in furtherance of any of the foregoing; or

(iii) an involuntary petition is filed against the Company (unless such petition is dismissed or discharged within 45 days under any bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is appointed to take possession, custody or control of any property of the Company).

(b) The Company shall promptly notify the Investor upon the occurrence of an Event of Default or if the Company has knowledge of or becomes aware of a pending or potential Event of Default.

(c) If there shall be any Event of Default hereunder, automatically upon the occurrence and during the continuation of an Event of Default under Section 5(a)(ii) or 5(a)(iii) and at the option of the Investor and upon written notice to the Company upon the occurrence and during the continuation of any other Event of Default, this Note shall accelerate and all principal and unpaid fees, expenses and other charges shall become promptly due and payable.
