AKOUSTIS TECHNOLOGIES, INC.

6.5% Convertible Senior Note due 2023

This Note is one of a duly authorized issue of Notes of the Company, designated as its 6.5% Convertible Senior Notes due 2023 (the “Notes”), limited to the aggregate principal amount of $10,000,000, all issued or to be issued under and pursuant to an Indenture dated as of October 23, 2018 (the “Base Indenture” as it may be amended or supplemented from time to time), by and among the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture dated as of October 23, 2018, between the Company and the Trustee (the “First Supplemental Indenture”, and together with the Base Indenture, the “Indenture”) to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes.

The indebtedness evidenced by the Notes constitute a senior general unsecured obligation of the Company ranking equally in right of payment with all existing and future senior unsecured indebtedness of the Company and ranking senior in right of payment to any future indebtedness of the Company that is expressly made subordinate to the Notes by the terms of such indebtedness.  The Company has the right to incur capital lease obligations and purchase money indebtedness for the purpose of financing the purchase price or cost of equipment used in its and its subsidiaries’ production lines and up to an additional $1 million of such indebtedness for other purposes. The Notes rank junior to any such indebtedness to the extent of the assets acquired with the proceeds thereof.

The interest rate to be borne by this Note shall be subject to increase as required to pay Special Interest pursuant to, and as set forth in, the Indenture.

The Notes may not be redeemed at the option of the Company at any time prior to November 30, 2019.

At any time and from time to time on or after November 30, 2019 the Company may, pursuant to Article 3 of the Indenture, redeem all or a portion of the Notes at a redemption price equal to 100% of the Principal Amount plus accrued and unpaid Interest on such Principal if any, as follows:

If the Company elects to exercise the Optional Redemption Right, the Company will make an Interest Make-Whole Payment to the Holder of such redeemed Note in cash in an amount equal to the sum of the remaining scheduled payments of Interest that would have been made on the Notes to be converted had such Notes remained outstanding from the Optional Redemption Date through and including the Stated Maturity, provided, that the Company shall have the option to make any Interest Make-Whole Payment in Freely Tradeable Common Stock, as determined by the Company pursuant to, and to the extent permitted by, the Indenture.

On November 30, 2021, the Holder may, pursuant to Section 3.08 of the Indenture, elect to require the Company to redeem all (but not less than all) of the Notes at a purchase price in cash equal to 100% of the Principal Amount to be repurchased, plus accrued and unpaid Interest to, and including, the Holder Optional Redemption Date.

In case certain Events of Default shall have occurred and be continuing, the Principal of, and Interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate Principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the Principal amount on the Stated Maturity, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Majority Holders, evidenced as in the Indenture provided, to modify the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Majority Holders may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

Each Holder shall have the right to receive payment or delivery, of (x) the Principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid Interest, if any, on, and (z) the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money and/or Freely Tradeable Common Stock, as the case may be, as determined by the Company pursuant to, and to the extent permitted by, the Indenture.

The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company designated by the Company for such purpose under the Indenture, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate Principal Amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. The Trustee and the Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into shares of Common Stock at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in Principal Amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. If any Holder elects to convert its Note in connection with a Qualifying Fundamental Change, the Company will make a Qualifying Fundamental Change Payment as provided in the Indenture.

If money for the payment of Principal or Interest, if any, remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to applicable unclaimed property laws. After that, Holders entitled to money must look to the Company for payment as general creditors unless applicable abandoned property law designates another person.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption or repurchase as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
