For value received Aeluma, Inc., a Delaware corporation (the “Company”), promises to pay to __________________ or its assigns (“Holder”) the principal sum of $[ ]¹ due and payable on the date and in the manner set forth below.

This convertible promissory note (the “Note”) is issued as part of a series of similar convertible promissory notes (collectively, the “Notes”) pursuant to the terms of that certain Note Purchase Agreement (as amended, the “Agreement”) dated as of __________ __, 2024 to the persons and entities listed on the Schedule of Investors attached to the Agreement (collectively, the “Holders”). Capitalized terms used herein without definition shall have the meanings given to such terms in the Agreement.

1. Repayment. All payments of interest and principal shall be in lawful money of the United States of America and shall be made pro rata among all Holders. All payments shall be applied first to accrued interest, and thereafter to principal. The outstanding principal amount of the Loan shall be due and payable on June 30, 2026 (the “Maturity Date”).

2. Interest Rate. The Note shall be interest free.

3. Conversion; Repayment Upon Sale of the Company.

(a) In the event that the Company issues and sells shares of its Equity Securities (as defined below) to investors (the “Investors”) on or before the date of the repayment in full of this Note in an equity financing resulting in gross proceeds to the Company of at least $5,000,000 (excluding the conversion of the Notes and any other indebtedness) (a “Qualified Financing”), then the outstanding principal balance of this Note shall automatically convert in whole without any further action by the Holder into such Equity Securities at a conversion price (the “Conversion Price”) equal to eighty-five percent (85%) of the per share price paid by the Investors in the Qualified Financing.

(b) In the event that Company’s securities are accepted for listing on a national securities exchange or market, whether or not in connection with a Qualified Financing, (an “Uplist”) then the outstanding principal balance of this Note shall automatically convert in whole without any further action by the Holder into shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) at a conversion price equal to eighty-five percent (85%) to the VWAP of the Common Stock on the OTC Markets for the five trading days immediately prior to the Uplist (the “Uplist Conversion Price”).

(c) In the event the Company does not complete a Qualified Financing or Uplist at or before the Maturity Date, then the outstanding principal balance of this Note shall automatically convert without any further action by the Holder into shares of the Company’s common stock equal to eighty-five percent (85%) to the VWAP of the Common Stock on the OTC Markets for the five trading days immediately prior to Maturity (the “Maturity Conversion Price”).

(d) Notwithstanding the foregoing, in no event shall the Conversion Price, Uplist Conversion Price or Maturity Conversion Price be lower than $[  ]² per share (the “Floor Price”) or higher than $3.50 per share (the “Ceiling Price”); which Floor Price and Ceiling Price shall automatically adjust in the event of a stock split or consolidation by the Company. If the then applicable conversion price (whether upon a Qualified Financing, at Uplist or at the Maturity Date) is below the Floor Price, the Floor Price shall be deemed to be the applicable conversion price. If the then applicable conversion price (whether upon a Qualified Financing, at Uplist or at the Maturity Date) is above the Ceiling Price, the Ceiling Price shall be deemed to be the applicable conversion price.

(e) If, after aggregation, the conversion of this Note would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of one share of the class and series of capital stock into which this Note has converted by such fraction.

(f) Notwithstanding any provision of this Note to the contrary, in the event that the Company consummates a Sale of the Company (as defined below) prior to the conversion or repayment in full of this Note, the Holder, at its election, (i) will receive a cash payment equal to the aggregate amount of principal then outstanding under the Note or (ii) provide written notice of exercise of a sale conversion. Upon receipt of any such notice, the then outstanding principal balance of this Note shall automatically convert in whole without any further action by the Holder into shares of the Company’s common stock equal to eighty-five percent (85%) of the VWAP of the Common Stock on the OTC Markets for the five trading days immediately prior to the Sale of the Company (the “Sale Conversion Price”). In no event shall the Sale Conversion Price be lower than the Floor Price or higher than the Ceiling Price; which Floor Price and Ceiling Price shall automatically adjust in the event of a stock split or consolidation by the Company. If the then applicable Sale Conversion Price is below the Floor Price, the Floor Price shall be deemed to be the applicable conversion price. If the then applicable Sale Conversion Price is above the Ceiling Price, the Ceiling Price shall be deemed to be the applicable conversion price.
