REGISTERED OWNER:

THIS CERTIFIES THAT the registered owner whose name is inscribed hereon is the owner of the number of non-transferable subscription rights (“Rights”) set forth above. The Rights entitle the holder thereof to subscribe for and purchase units of Pulse Biosciences, Inc., a Delaware corporation (the “Company”), each unit consisting of one share of common stock, par value $0.001 per share (the “Common Stock”) and a warrant to purchase one share of Common Stock, only during a limited time (the “Units”, and each, a “Unit”), at a subscription price per full Unit equal to the lesser of (i) $3.72 (the “Initial Price”) and (ii) the volume weighted average price of the Common Stock for the five trading day period through and including the Expiration Date (the “Alternate Price”), pursuant to a rights offering (the “Rights Offering”), on the terms and subject to the conditions set forth in the prospectus dated August 21, 2020, as supplemented by the prospectus supplement dated May 4, 2022 (collectively, the “Prospectus”).

Each Right includes a subscription right. Under the subscription right, for each share of common stock owned as of the record date of the Rights Offering, the holder hereof is entitled to purchase 0.13530032 Units at the Initial Price per full Unit.

The Rights represented by this Subscription Rights Certificate may be exercised by completing Section 1 and any other appropriate sections herein and by returning the full payment of the subscription price for each Unit in accordance with the instructions contained herein. If, on the Expiration Date, the Alternate Price is lower than the Initial Price, any excess subscription amounts paid will be put towards the purchase of additional Units (either towards basic subscription rights, if available, or towards the over-subscription right if the basic subscription rights have already been exercised in full).

SECTION 1 – EXERCISE OF SUBSCRIPTION RIGHTS

To subscribe for Units pursuant to your Rights, please complete lines (a) and (b) and sign in part (c). If you do not indicate the number of Rights being exercised, or if you do not forward the full subscription payment for the number of Rights that you indicate are being exercised, then you will be deemed to have exercised the maximum number of Rights that may be exercised with the aggregate subscription payment you timely delivered to the Subscription Agent. Fractional Units resulting from the exercise of the subscription rights will be eliminated by rounding down to the nearest whole number, with the total subscription payment being adjusted accordingly. Any excess subscription payments received by the Subscription Agent will be returned, without interest, as soon as practicable. The common stock and warrants comprising the Units will separate upon the closing of the rights offering and will be issued separately, however, they may only be purchased as a Unit and the Units will not trade as a separate security. Each warrant will be exercisable for one share of Common Stock at an exercise price equivalent to the subscription price through its expiration five years from the date of issuance. The number of warrants issued to you will be calculated by rounding down to the nearest whole number the number of Units you subscribe for.
