OF

LIFESCI ACQUISITION III CORP.

[__] 2021

W-[__]

This is to Certify That, FOR VALUE RECEIVED, LIFESCI HOLDINGS LLC, or his, her or its assigns (“Holder”), is entitled to purchase, subject to the provisions of this Warrant, from LIFESCI ACQUISITION III CORP., Delaware corporation (the “Company”), 3,033,333 fully paid, validly issued and nonassessable shares of the Company’s common stock, par value $0.0001 per share (the “Shares”) at a price of $11.50 per share. The number of Shares to be received upon the exercise of this Warrant and the price to be paid for each Share may be adjusted from time to time as hereinafter set forth. The Shares deliverable upon such exercise, as adjusted from time to time, are hereinafter sometimes referred to as “Warrant Shares,” and the exercise price for a Share in effect at any time, as adjusted from time to time, is hereinafter sometimes referred to as the “Exercise Price.”

(a) EXERCISE OF WARRANT. This Warrant may be exercised in whole or in part at any time on the later of (i) 30 days after the consummation by the Company of its initial merger, share exchange, asset acquisition, share purchase, reorganization or other similar business combination with one or more businesses or entities (the “Business Combination”) (as described more fully in the Registration Statement on Form S-1 (No. 333-[__]) as filed with the Company or (ii) 12 months from the closing of the public offering of the Company’s Shares, and terminating at 5:00 p.m., New York City time on five years from the consummation of the Business Combination (the “Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide at least ten (10) days’ prior written notice of any such extension to registered holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

(1) This Warrant may be exercised by presentation and surrender hereof to the Company at its principal office with the Purchase Form annexed hereto (the “Purchase Form”) duly executed and accompanied by payment of the Exercise Price for the number of Warrant Shares specified in such Purchase Form (which may take the form of a “cashless exercise” pursuant to Section (a)(2) if so indicated in the Purchase Form).

(2) The Holder shall pay the Exercise Price in immediately available funds; provided, however, that the Holder may, in the Holder’s sole discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = Y(A-B)/A

where

X = the number of Warrant Shares to be issued to the Holder.

Y = the total number of Warrant Shares with respect to which this Warrant is being exercised.

A = the Fair Market Value (as defined below) of one Share on the trading day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise.”

B = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

For purposes of this Warrant, “Fair Market Value” means, for any security as of any date, the price determined by the first of the following clauses that applies: (a) if the Shares are then listed on a national securities exchange, the daily volume weighted average price of the Shares for such date (or the nearest preceding date) on the trading market on which the Shares are then listed as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:00 p.m. (New York City time)), (b) if the Shares are quoted on the OTC Bulletin Board or the OTC Market, the average closing bid price on such market for the five most recently completed trading days, (c) if paragraphs (a) or (b) are not applicable, if an appraiser hired by the Company has provided a report on the fair market value of a Share within the 12-month period preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” the fair market value of a share of Shares as determined by such appraiser, or (d) if none of the foregoing is applicable, the price determined by the Board of Directors of the Company in good faith.

(b) EFFECTIVE TIME OF EXERCISE. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which the Purchase Form has been delivered to the Company (the “Exercise Date”) as provided in Section (a). At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in Section (c) below shall be deemed to

2

have become the holder or holders of record of the Warrant Shares represented by such certificates. Notwithstanding the foregoing, if the Holder or any assignee does not enter into the Shareholders’ Agreement within three (3) business days of being requested to do so by the Company, then the exercise of this Warrant will be deemed to not have been effective and void ab initio and the Holder or any assignee shall return any securities received by them pursuant to Section (c) to the Company.

(c) DELIVERY TO HOLDER.

(1) As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within five (5) business days thereafter, the Company will cause to be issued in the name of, and delivered to, the Holder, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct:

(A) a certificate or certificates for the number of Warrant Shares to which such Holder shall be entitled, and

(B) in case such exercise is in part only, a new warrant or warrants of like tenor, exercisable for in the aggregate the number of Shares equal (giving effect to any adjustment therein) to the number of Shares called for on the face of this Warrant minus the number of such shares purchased by the Holder upon such exercise.

(2) To the extent permitted by law and except as provided in this Warrant, the Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or entity or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other person or entity of any obligation to the Company or any violation or alleged violation of law by the Holder or any other person or entity, and irrespective of any other circumstance that might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing Warrant Shares upon exercise of the Warrant as required pursuant to the terms hereof.

(d) RESERVATION OF SHARES. The Company shall at all times reserve for issuance and/or delivery upon exercise of this Warrant such number of Shares (as adjusted pursuant to the terms hereof) as shall be required for issuance and delivery upon exercise of this Warrant. The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. The Company will take all such action as may be reasonably necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Shares may be listed.

3

(e) FRACTIONAL SHARES. No fractional shares or scrips representing fractional shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a share called for upon any exercise hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the fair market value of a Share.

(f) LOSS OR DESTRUCTION OF WARRANT. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Warrant, if mutilated, the Company will execute and deliver a new Warrant of like tenor and date.

(g) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or equity, and the rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the Company except to the extent set forth herein.

(h) CERTAIN ADJUSTMENTS. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section (h).

(1) Share Capitalizations and Sub-Divisions. If the Company, at any time while this Warrant is outstanding, (i) declares a share capitalization on its Shares or otherwise makes a distribution on any class of shares that is payable in Shares, (ii) subdivides its outstanding Shares into a larger number of shares, or (iii) combines its outstanding Shares into a smaller number of shares, then, in each such case, the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the number Shares outstanding immediately before such event and the denominator of which shall be the number of Shares outstanding immediately after such event. Any adjustment made pursuant to this Section (h)(1) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this Section (h)(1) shall become effective immediately after the effective date of such subdivision or combination.

(2) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section (h)(1), the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

(3) Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects any merger or consolidation of the Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets or a majority of its Shares is acquired by a third party, in each case, in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or a third party that is conducting such an offer pursuant to an agreement or arrangement with the Company) is completed pursuant to which all or substantially all of the holders of Shares are permitted to tender or exchange their shares for other securities, cash or property, or (iv) the Company effects any reorganization or reclassification of Shares or any compulsory share exchange pursuant to

4

which the Shares are effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of Shares covered by Section (h)(1) above) (in any such case, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein (the “Alternate Consideration”). The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof, any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or Person shall assume the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Warrant. The provisions of this Section (h)(3) shall similarly apply to subsequent transactions analogous of a Fundamental Transaction type.

(4) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section (h), the Company at its expense will, at the written request of the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other property issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

(5) Notices To Warrant Holders. So long as this Warrant shall be outstanding, (i) if the Company shall pay any dividend or make any distribution of cash, securities or other property in respect of its Shares or (ii) if the Company shall offer to the holders of Shares for subscription or purchase by them any share of any class or any other rights or (iii) if any capital reorganization of the Company, reclassification of the shares of the Company, consolidation or merger of the Company with or into another corporation, sale, lease or transfer of all or substantially all of the property and assets of the Company to another corporation, if the Company authorizes or approves, enters into any agreement contemplating or solicits shareholder approval for any Fundamental Transaction (each as defined below) , or voluntary or involuntary dissolution, liquidation or winding up of the Company shall be effected, then in any such case, the Company shall cause to be mailed to the Holder, at least fifteen days prior the date specified in (x) or (y) below, as the case may be, a notice containing a brief description of the proposed action and stating the date on which (x) a record is to be taken for the purpose of such dividend, distribution or rights, or (y) such reclassification, reorganization, consolidation, merger, conveyance, lease, Fundamental Transaction, sales or issuances, dissolution, liquidation or winding up is to take place and the date, if any is to be fixed, as of which the holders of Shares or other securities shall receive cash or other property deliverable upon such reclassification, reorganization, consolidation, merger, conveyance, lease, Fundamental Transaction, sales or issuances, dissolution, liquidation or winding up.
