Exhibit 10.24

AMENDED AND RESTATED SECURED FULL RECOURSE PROMISSORY NOTE

(This Amended and Restated Secured Full Recourse Promissory Note (the “Note”) supersedes in

its entirety that certain Secured Full Recourse Promissory Note dated as of April 18, 2016 (the

“Original Note”), previously representing the indebtedness set forth below, which previous Note

shall have no further force or effect.)

FOR VALUE RECEIVED the undersigned, Daniel Schwartz (the “Maker”), promises to pay to RxSight, Inc., a California corporation (f/k/a Calhoun Vision, Inc.) (the “Payee”), or its registered assigns, in Aliso Viejo, California, or at such other place as Payee may from time to time designate, in lawful money of the United States of America the principal sum of ONE HUNDRED SIXTY THOUSAND DOLLARS ($160,000.00), or such lesser amount as shall equal the outstanding principal amount hereof, together with (i) interest from the date of this Note on the unpaid principal balance at a rate equal to seven percent (7.00%) compounded annually, computed on the basis of the actual number of days elapsed and a year of 365 days, and (ii) interest of Thirty Six Thousand Forty Nine and 52/100 Dollars ($36,049.52) accrued to the date hereof on the principal amount of the Original Note, that at this Note amends, restates and supersedes.

The principal amount under this Note and any accrued and unpaid interest shall be due and payable in full on April 18, 2022 (the “Maturity Date”). Notwithstanding the foregoing, the entire unpaid principal sum and accrued interest under this Note shall become immediately due and payable upon the earlier to occur of (i) a Change of Control (as defined below) of Payee, (ii) a firm commitment underwritten public offering of Payee’s common stock to be registered under the Securities Act of 1933, as amended, or (iii) the sale or transfer of all of the shares of Common Stock subject to the Pledge Agreement (the “Pledged Securities”). As used herein, “Change in Control” means (i) a sale of all or substantially all of Payee’s assets, (ii) any merger, consolidation or other business combination transaction of Payee with or into another corporation, entity or person, other than a transaction in which the holders of at least a majority of the shares of voting capital stock of Payee outstanding immediately prior to such transaction continue to hold (either by such shares remaining outstanding or by their being converted into shares of voting capital stock of the surviving entity) a majority of the total voting power represented by the shares of voting capital stock of Payee (or the surviving entity) outstanding immediately after such transaction, or (iii) the direct or indirect acquisition (including by way of a tender or exchange offer) by any person, or persons acting as a group, of beneficial ownership or a right to acquire beneficial ownership of shares representing a majority of the voting power of the then outstanding shares of capital stock of Payee. “Director” means any individual who is a member of the Board of Directors of Payee.

If any interest is determined to be in excess of the then legal maximum rate, then that portion of each interest payment representing an amount in excess of the then legal maximum rate shall be deemed a payment of principal and applied against the principal of the obligations evidenced by this Note.

Maker shall have the right to prepay all or any part of the unpaid principal amount of this Note from time to time without any penalty or premium. Any payments made under this Note shall be applied first against any accrued interest, and then against the outstanding principal balance.

In the event Maker proposes to sell or otherwise transfer any portion of the Pledged Securities, Maker shall, as a condition to such sale or transfer, prepay in cash, that portion of the then outstanding principal of this Note, together with the accrued and unpaid interest with respect to the amount to be prepaid as of the date of such prepayment. The principal amount to be so prepaid shall equal the number of shares

to be sold or transferred, multiplied by the price per share originally paid by Maker for the Pledged Securities ($0.40 per share), subject to adjustment for stock splits, dividends, recapitalizations or other similar events. Maker shall deliver the principal and interest required to be so prepaid to the company on or prior to the effective date of any such transfer or sale. Upon receipt of the required prepayment by the Payee, Payee shall release the number of Pledged Securities sold or transferred from the security interest created by the Pledge Agreement and shall issue additional certificates representing the sold or transferred shares as may be necessary to effect such sale or transfer. Payee shall make appropriate annotations on the face of this Note to reflect the receipt of such payment and transfer and release of the respective Pledged Securities. Notwithstanding the foregoing, in the event Payee enters into a transaction, the result of which is the purchase by another from Maker of any shares of Pledged Securities, Maker may direct such purchaser to deliver all or a portion of the consideration to be revised by Maker in such transaction to Payee in satisfaction of Makers obligation to prepay in the event of a transfer or sale of a portion of the Pledged Securities. Payee shall apply any amounts so received to the prepayment of this Note as though Maker had paid such amounts directly to Payee.

Consent by the Payee to waive one default shall not be deemed to be a waiver of the right to require consent to waive future or successive defaults.

This Note is secured pursuant to that certain Stock Pledge Agreement, dated as of the date hereof, by and between Maker and Payee and attached hereto as Exhibit A (the “Pledge Agreement”). For the avoidance of doubt, and without in any manner impairing the validity of this Note, the Pledge Agreement or any security interest created thereof, this Note shall be “full recourse” such that in the event of any default under the terms of this Note, Payee may hold Maker personally liable for payment of the obligations evidenced by this Note or for any other sums due as a result of any defaults under this Note. The security interest created pursuant to the Original Note in the Pledged Collateral is hereby superseded and replaced in its entirety by the security interest in the Pledged Collateral created pursuant to the Pledge Agreement.

Maker hereby waives presentment, demand, notice of dishonor, protest, notice of protest and all other demands, protests and notices in connection with the execution, delivery, performance, collection and enforcement of this Note. The Maker shall pay all costs of collection when incurred, including reasonable attorneys’ fees, costs and expenses.

This Note is being delivered in, is intended to be performed in, shall be construed and interpreted in accordance with, and be governed by the internal laws of, the State of California, without regard to principles of conflict of laws.

This Note may only be amended, modified or terminated by an agreement in writing signed by the party to be charged. This Note shall be binding upon the heirs, executors, administrators, successors and assigns of the Maker and inure to the benefit of the Payee and its permitted successors, endorsees and assigns. This Note shall not be transferred without the express written consent of Payee, provided that if Payee consents to any such transfer or if notwithstanding the foregoing such a transfer occurs, then the provisions of this Note shall be binding upon any successor to Maker and shall inure to the benefit of and be extended to any holder thereof.

7.    Voting Rights; Dividends; Etc.

(a)    Rights Prior to an Event of Default. So long as no Event of Default shall have occurred and be continuing:

(i)    Debtor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Pledged Securities or any part thereof for any purpose not inconsistent with the terms of this Pledge Agreement.

(ii)    Debtor shall be entitled to receive and retain free and clear of the security interest of Secured Party hereunder any and all dividends and interest paid in respect of the Pledged Securities, provided, however, that any and all (A) dividends and interest paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for any Pledged Securities, (B) dividends and other distributions paid or payable in cash in respect of any Pledged Securities in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid-in-surplus, and (C) cash paid, payable or otherwise distributed in respect of principal of, or in redemption of, or in exchange for, any Pledged Securities, shall be, and shall be forthwith

delivered to Secured Party to hold as, Pledged Collateral and shall, if received by Debtor, be received in trust for the benefit of Secured Party, be segregated from the other property or funds of Debtor and be forthwith delivered to Secured Party as Pledged Collateral in the same form as so received (with any necessary endorsement) to be held as part of the Pledged Collateral.

(b)    Rights Following an Event of Default. Upon the occurrence and during the continuance of an Event of Default:

(i)    All rights of Debtor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 7(a)(i) and to receive the dividends and interest payments which it would otherwise be authorized to receive and retain pursuant to Section 7(a)(ii) shall cease and all such rights shall thereupon become vested in Secured Party which shall thereupon have the sole right, but not the obligation, to exercise such voting and other consensual rights and to receive and hold as Pledged Collateral such dividends and interest payments.

(ii)    All dividends and interest payments which are received by Debtor contrary to the provisions of subparagraph (i) of this Section 7(b) shall be received in trust for the benefit of Secured Party, shall be segregated from other funds of Debtor and shall be forthwith delivered to Secured Party as Pledged Collateral in the same form as so received (with any necessary endorsement).

8.    Events of Default; Remedies.

(a)    Event of Default. An Event of Default shall be deemed to have occurred upon the occurrence and during the continuance of any breach of any terms of the Note (an “Event of Default”), including, without limitation, if the Debtor shall fail to pay (i) when due any principal payment on the Maturity Date under the Note, or (ii) any interest payment or other payment required under the terms of the Note and such payment shall not have been made within ten (10) business days of the Secured Party’s receipt of written notice to the Secured Party of such failure to pay.

(c)    Sale of Pledged Collateral. Debtor acknowledges and recognizes that Secured Party may be unable to effect a public sale of all or a part of the Pledged Securities and may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obligated to agree, among other things, to acquire the Pledged Securities for their own account, for investment and not with a view to the distribution or resale thereof. Debtor acknowledges that any such private sales may be at prices and on terms less favorable to Secured Party than those of public sales, and agrees that so long as such sales are made in good faith such private sales shall be deemed to have been made in a commercially reasonable manner and that Secured Party has no obligation to delay sale of any Pledged Securities to register such securities for public sale under the Securities Act of 1933, as amended, or under any state securities law.

(d)    Notice, Etc. In any case where notice of sale is required, ten (10) business days’ notice shall be deemed reasonable notice.

as Secured Party shall request concerning Debtor’s ownership of the Pledged Securities; and (ii) Secured Party or its nominee shall have the right, but shall not be obligated, to vote or give consent with respect to the Pledged Securities or any part thereof.

9.    Secured Party Appointed Attorney-in-Fact.

Debtor hereby appoints Secured Party as Debtor’s attorney-in-fact, with full authority in the place and stead of Debtor and in the name of Debtor or otherwise, from time to time in Secured Party’s discretion and to the full extent permitted by law to take any action and to execute any instrument which Secured Party may deem reasonably necessary or advisable to accomplish the purposes of this Pledge Agreement in accordance with the terms and provisions hereof, including without limitation, to receive, endorse and collect all instruments made payable to Debtor representing any dividend, interest payment or other distribution in respect of the Pledged Collateral or any part thereof and to give full discharge for the same.

Debtor hereby ratifies all reasonable actions that said attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable. The powers conferred on Secured Party hereunder are solely to protect its interests in the Pledged Collateral and shall not impose any duty upon Secured Party to exercise any such powers. Secured Party shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and in no event shall Secured Party or any of its officers, directors, employees or agents be responsible to Debtor for any act or failure to act, except for gross negligence or willful misconduct.

(c)    Amendments and Waivers. This Pledge Agreement may not be amended or modified, nor may any of its terms be waived, except by written instruments signed by Debtor and Secured Party. Each waiver or consent under any provision hereof shall be effective only in the specific instances for the purpose for which given.

Debtor shall pay on demand all reasonable fees and expenses, including reasonable attorneys’ fees and expenses, incurred by Secured Party with respect to any amendments or waivers hereof requested by Debtor or in the enforcement or attempted enforcement of any of the Obligations or in preserving any of Secured Party’s rights and remedies (including, without limitation, all such fees and expenses incurred in connection with any “workout” or restructuring affecting this Agreement, the Note or the Obligations or any bankruptcy or similar proceeding involving Debtor or any of its subsidiaries).
