Re: Sponsor Support Agreement 
 Ladies and Gentlemen: 

This letter agreement (this “Sponsor Agreement”) is being delivered to Healthcare Capital Corp., a Delaware corporation
(“SPAC”), and Alpha Tau Medical Ltd., a company organized under the laws of the State of Israel (the “Company”), in accordance with that certain Agreement and Plan of Merger, dated as of the date hereof, by and
among SPAC, the Company, and the other parties thereto (the “Merger Agreement”) and the transactions contemplated thereby or relating thereto (including the PIPE Financing, the “Business Combination”) and hereby
amends and restates in its entirety that certain letter, dated January 14, 2021, from Healthcare Capital Sponsor LLC, a Delaware limited liability company (the “Sponsor”), and the undersigned individuals, each of whom is a
member of SPAC’s board of directors (the “SPAC Board”) or management team (each, an “Insider” and collectively, the “Insiders”), to SPAC (the “Prior Letter Agreement”). Certain
capitalized terms used herein are defined in Section 12 hereof. Capitalized terms used but not otherwise defined herein have the respective meanings ascribed to such terms in the Merger Agreement. 

The Sponsor and each Insider hereby acknowledges and agrees that, as of the date hereof, the Prior Letter Agreement shall terminate and be of no further force
or effect without any further liability thereunder. 
 Unless the context of this Sponsor Agreement otherwise requires, (i) words of any gender include
each other gender, (ii) words using the singular or plural number also include the plural or singular number, respectively, (iii) the terms “hereof,” “herein,” “hereby,” “hereto” and derivative or
similar words refer to this entire Sponsor Agreement, (iv) the terms “Section” and “Schedule” refer to the specified Section or Schedule of or to this Sponsor Agreement unless otherwise specified, (v) the word
“including” shall mean “including without limitation,” (vi) the word “or” shall be disjunctive but not exclusive and have the meaning represented by the term “and/or”, and (vii) the phrase “to the
extent” means the degree to which a subject matter or other thing extends, and such phrase shall not mean simply “if”. 
 In order to induce
the Company and SPAC to enter into the Merger Agreement and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Sponsor and each Insider hereby agrees with SPAC and, at all times prior to any
valid termination of the Merger Agreement, the Company as follows: 
  

	1)	 The Sponsor and each Insider irrevocably agrees that it, he or she shall: 



 

	 	a)	 vote all SPAC Class A Shares and Founder Shares owned by it, him or her (all such common stock, the
“Covered Shares”) in favor of the Business Combination and each other proposal related to the Business Combination included on the agenda for the special meeting of stockholders of SPAC relating to the Business Combination;



  

	 	b)	 when such meeting of stockholders is held, appear at such meeting or otherwise cause such Covered Shares to be
counted as present thereat for the purpose of establishing a quorum; 



  
 1 














	 	c)	 vote (or execute and return an action by written consent), or cause to be voted at such meeting, or validly
execute and return and cause such consent to be granted with respect to, all of such Covered Shares against any SPAC Alternative Transaction Proposal or any other action that would reasonably be expected to impede, interfere with, delay, postpone or
adversely affect the Merger or any of the other transactions contemplated by the Merger Agreement or result in a breach of any covenant, representation or warranty or other obligation or agreement of SPAC under the Merger Agreement or any other
agreement entered into in connection with the Business Combination or result in any of the conditions set forth in Article IX of the Merger Agreement not being fulfilled, result in a breach of any covenant, representation or warranty or other
obligation or agreement of the Sponsor or the Insiders contained in this Sponsor Agreement or change in any manner the dividend policy or capitalization of, including the voting rights of, any class of Equity Securities; 



 

	 	d)	 vote (or execute and return an action by written consent), or cause to be voted at such meeting, or validly
execute and return and cause such consent to be granted with respect to, all of such Covered Shares against any change in business, management or board of directors of SPAC (other than in connection with the Business Combination as contemplated by
the Transaction Agreements); and 


  

	 	e)	 not redeem, or seek to redeem, any Covered Shares owned by it, him or her in connection with such shareholder
approval or otherwise. 


 Prior to any valid termination of the Merger Agreement in accordance with its terms, the Sponsor
and each Insider shall take, or cause to be taken, all actions and do, or cause to be done, all things reasonably necessary under applicable Laws to consummate the Business Combination, the PIPE Financing and the other transactions contemplated by
the Merger Agreement or any other Transaction Agreement, in each case on the terms and subject to the conditions set forth therein. 
 The
obligations of the Sponsor specified in this Section 1 shall apply whether or not the Merger or any action described above is recommended by the SPAC Board or if the SPAC Board has changed, withdrawn, withheld, amended,
qualified or modified, or (privately or publicly) proposed to change, withdraw, withhold, amend, qualify or modify the SPAC Board Recommendation; provided that nothing herein shall amend, limit or otherwise modify any obligation contained in
the Merger Agreement (including Section 7.08 thereof). 
  

	2)	 The Sponsor and each Insider hereby agrees and acknowledges that SPAC and, prior to any valid termination of
the Merger Agreement in accordance with its terms, the Company, would be irreparably injured in the event of a breach by the Sponsor or any Insider of its, his or her obligations under Section 1 or
Section 3, as applicable, of this Sponsor Agreement. Further, monetary damages would not be an adequate remedy for any breach described in the foregoing sentence and the non-breaching
party shall be entitled to seek an injunction, specific performance or other equitable relief, in addition to any other remedy that such party may have in law or in equity, in the event of any such breach (without providing any bond or other
security in connection with any such remedy). The Sponsor and each Insider hereby agrees that it will not allege, and hereby waives the defense, that SPAC or the Company, as applicable, has an adequate remedy at law or that an award of specific
performance is not an appropriate remedy for any reason at law or equity. 


  

	3)	 Transfers. 


  

	 	a)	 Without the prior written consent of the Company (which may be withheld in the Company’s sole and absolute
discretion), no Sponsor or Insider, as applicable, shall Transfer any Founder Shares, Private Placement Warrants or other Equity Securities of SPAC until the earlier of (i) without limiting Section 3(b), the
consummation of the Closing (the “Effective Time”) or (ii) the valid termination of the Merger Agreement in accordance with its terms. 


  

	 	b)	 In the event the Business Combination is consummated, none of the Sponsor and each Insider shall Transfer any
Equity Securities of the Company Beneficially Owned by it, him or her immediately following the Effective Time (such Equity Securities, the “Lock-Up Securities” and such obligation not to
Transfer, the “Founder Shares Lock-up”) during the period beginning on the Closing Date and continuing through the date that is one year after the Closing Date. Notwithstanding the foregoing,
if, subsequent to the Effective Time, the volume-weighted average price of Company Ordinary Shares on NASDAQ (or the U.S. exchange on which the Company Ordinary Shares are then listed) exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like recapitalization) for any 20 trading days within any 30-trading day period commencing at
least 150 days after the Closing Date, the Lock-Up Securities shall be released from the Founder Shares Lock-up. 



  
 2 














	 	c)	 Notwithstanding the provisions set forth in Sections 3(a) or 3(b), Transfers of the Founder
Shares, Private Placement Warrants or other Equity Securities of SPAC or the Company, as applicable, and that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this
Section 3(c)), are permitted (i) to SPAC’s officers or directors, any immediate family member of any of SPAC’s officers or directors or any affiliate of the Sponsor or to any member(s) of the Sponsor or any
of their affiliates; (ii) in the case of an individual, by gift to a member of such individual’s immediate family or to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such
individual or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution upon death of such individual; (iv) in the case of an individual, pursuant to a qualified domestic relations
order; (v) solely with the prior written consent of the Company in respect of each and every instance, by private sales or transfers made in connection with the consummation of the Business Combination at prices no greater than the price at
which the shares or warrants were originally purchased; or (vi) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; provided, however, that in
the case of clauses (i) through (vi), such permitted transferees must, before any such Transfer is effected, enter into a written agreement with SPAC (if prior to the Effective Time) and the Company agreeing to be bound by this Sponsor
Agreement (including the provisions relating to voting, the Trust Account, transfer restrictions and liquidating distributions). 


  

	4)	 Sponsor and each Insider hereby agrees that, during the period commencing on the date hereof and ending at the
Effective Time, Sponsor and each Insider shall not enter into, amend, supplement or otherwise modify any Contract between or among Sponsor or such Insider, anyone related by blood, marriage or adoption to such Insider or any Affiliate of such Person
(other than SPAC and its Subsidiaries), on the one hand, and SPAC or any of SPAC’s Subsidiaries, on the other hand. 


  

	5)	 Sponsor and each Insider hereby irrevocably and unconditionally waives and agrees not to assert, claim or
perfect any rights to adjustment or other anti-dilution protection with respect to the rate that the Founder Shares held by him, her or it converts into SPAC Class A Shares pursuant to Section 4.3(b)(ii) of the SPAC A&R Certificate of
Incorporation or any other anti-dilution protections or other adjustment or similar protection that arise in connection with the issuance of Equity Securities of SPAC or the Company. 



 

	6)	 Sponsor and each Insider hereby represents and covenants that Sponsor and such Insider has not entered into,
and shall not enter into, any Contract that could restrict, limit or interfere with the performance of Sponsor’s or such Insider’s obligations hereunder. 



 

	7)	 Sponsor and each Insider has full right and power, without violating any agreement to which it is a party or by
which it is bound (including any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Sponsor Agreement and perform
its obligations hereunder. 


  

	8)	 The Sponsor and certain Insiders are currently, and as of the Closing will be, the record owners of all of the
outstanding Founder Shares and outstanding Private Placement Warrants. The Sponsor and Insiders’ ownership of Equity Securities of SPAC, as of the date hereof, is set forth on Schedule A hereto. As of the date of this Sponsor Agreement and as
of the Closing, neither Sponsor nor any Insider nor any of their respective Affiliates (i) owns of record or Beneficially Owns any Equity Securities of SPAC, except as set forth on Schedule A or (ii) has made any loans, or otherwise
provided any funding, to SPAC except as expressly set forth on Schedule A. 


 9) 

 

	 	a)	 The Sponsor hereby agrees that immediately prior to the Effective Time, the Sponsor shall automatically be
deemed to irrevocably transfer to SPAC, surrender and forfeit (and the Sponsor shall take all actions necessary to effect such transfer, surrender and forfeiture) for no consideration, the Sponsor Equity set forth on Part I of Schedule B.



  

	 	b)	 The Sponsor hereby agrees that in the event that the Aggregate Transaction Proceeds are less than or equal to
$225,000,000, the Sponsor shall, immediately prior to the Effective Time, automatically be deemed to irrevocably transfer to SPAC, surrender and forfeit (and the Sponsor shall take all actions necessary to effect such transfer, surrender and
forfeiture) for no consideration the Sponsor Equity set forth on Part II of Schedule B (“Redemption Equity”) (for the avoidance of doubt, such transfer, surrender and forfeiture shall be in addition to the transfer, surrender and
forfeiture of the Sponsor Equity pursuant to Section 9(a)). 



  
 3 














	 	c)	 The Sponsor hereby agrees that in the event that the Aggregate Transaction Proceeds exceed $225,000,000 but are
less than $250,000,000, the Sponsor shall, immediately prior to the Effective Time, automatically be deemed to irrevocably transfer to SPAC, surrender and forfeit (and the Sponsor shall take all actions necessary to effect such transfer, surrender

$25,000,000 (for the avoidance of doubt, such transfer, surrender and forfeiture shall be in addition to the transfer, surrender and forfeiture of the Sponsor Equity pursuant to Section 9(a)). 



 

	 	d)	 The Sponsor hereby agrees that notwithstanding anything to the contrary contained herein or in the Merger
Agreement, the Equity Securities of the Company set forth on Part III of Schedule B (“Conditional Equity”) shall not vest as of the Effective Time but instead shall only vest if, during the period beginning on the Closing Date and
continuing through the date that is three years after the Closing Date (the “Earnout Period”), the volume-weighted average price of Company Ordinary Shares on NASDAQ (or the U.S. exchange on which the Company Ordinary Shares are
then listed) exceeds $14.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like recapitalization) for 20 trading days within any 30-trading day period (the “Earnout Condition”). If the Earnout Condition is not satisfied, the Conditional Equity shall not vest and the Sponsor shall, immediately as of the expiration of the
Earnout Period, automatically be deemed to irrevocably transfer to the Company, surrender and forfeit (and the Sponsor shall take all actions necessary to effect such transfer, surrender and forfeiture) for no consideration the Conditional Equity.
During the Earnout Period, subject to Section 3(c), the Sponsor shall not Transfer the Conditional Equity. 


  

	10)	 At the Closing, each of the Company and the Persons set forth on Schedule A hereto will enter into a joinder to

	16)	 This Sponsor Agreement may be executed in any number of original, electronic or facsimile counterparts and each
of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. 


  


	17)	 This Sponsor Agreement shall be deemed severable, and the invalidity or unenforceability of any term or
provision hereof shall not affect the validity or enforceability of this Sponsor Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there

state, without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction. Any Action based upon, arising out of or related to this Sponsor
Agreement or the transactions contemplated hereby shall be brought in the Delaware Court of Chancery, and if the Delaware Court of Chancery does not have or take jurisdiction over such Action, any other federal or state courts located in the State
of Delaware, and each of the Parties irrevocably submits to the exclusive jurisdiction of each such court in any such Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that
all claims in respect of the Action shall be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Sponsor Agreement or the transactions contemplated hereby in any other court. Nothing
herein contained shall be deemed to affect the right of any Party to serve process in any manner permitted by Law or to commence legal proceedings or otherwise proceed against any other Party in any other jurisdiction, in each case, to enforce
judgments obtained in any Action brought pursuant to this Section 18. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS SPONSOR
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 5

terms. In the event of a valid termination of the Merger Agreement in accordance with its terms, this Sponsor Agreement shall be of no force and effect and shall revert to the Prior Letter Agreement. No such termination or reversion shall relieve
the Sponsor, each Insider, SPAC or the Company from any liability resulting from a breach of this Sponsor Agreement occurring prior to such termination or reversion. 



 

	21)	 The Sponsor and each Insider hereby represents and warrants (severally and not jointly as to itself, himself or
herself only) to SPAC and the Company as follows: (i) if such Person is not an individual, it is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it is organized, and such party has all necessary

deliver this Sponsor Agreement and to perform his or her obligations hereunder; (iii) such Person is not an Israeli resident for Tax purposes; (iv) this Sponsor Agreement has been duly executed and delivered by such Person and, assuming

individual, conflict with or result in a violation of the organizational documents of such Person, or (B) require any consent or approval that has not been given or other action that has not been taken by any third party (including under any
Contract binding upon such Person or such Person’s Founder Shares or Private Placement Warrants), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Person of
his, her or its obligations under this Sponsor Agreement; (vi) there are no Actions pending against such Person or, to the knowledge of such Person, threatened against such Person, before (or, in the case of threatened Actions, that would be
before) any arbitrator or any Governmental Authority, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Person of its, his or her obligations under this Sponsor Agreement; (vii) except for
fees described on Schedule 5.07 of the Merger Agreement, no financial advisor, investment banker, broker, finder or other similar intermediary is entitled to any fee or commission from such Person, SPAC, any of its Subsidiaries or any of their
respective Affiliates in connection with the Merger Agreement or this Sponsor Agreement or any of the respective transactions contemplated thereby and hereby, in each case, based upon any arrangement or agreement made by or, to the knowledge of such
Person, on behalf of such Person, for which SPAC, the Company or any of their respective Affiliates would have any obligations or liabilities of any kind or nature; (viii) such Person has had the opportunity to read the Merger Agreement and
this Sponsor Agreement and has had the opportunity to consult with its tax and legal advisors; (ix) such Person has not entered into, and shall not enter into, any agreement that would restrict, limit or interfere with the performance of such

(B) the SPAC A&R Certificate of Incorporation, (C) the Merger Agreement, or (D) the Registration Rights Agreement, dated as of January 14, 2021, by and among SPAC and certain security holders; and (xi) none of such
Founder Shares or Private Placement Warrants is subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Founder Shares or Private Placement Warrants, except as provided in this Sponsor Agreement.




  
 6 














	22)	 If, and as often as, (a) there are any changes in SPAC, the SPAC Class A Shares, the SPAC
Class B Shares, the SPAC Warrants or any other Equity Securities of SPAC by way of stock split, stock dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or business combination, or by
any other similar means that result in Sponsor acquiring new SPAC Class A Shares, SPAC Class B Shares, SPAC Warrants or any other Equity Securities of SPAC, (b) Sponsor purchases or otherwise acquires beneficial ownership of any
shares of the SPAC Class A Shares, the SPAC Class B Shares, SPAC Warrants or any other Equity Securities of SPAC after the date of this Sponsor Agreement, or (c) Sponsor acquires the right to vote or share in the voting of any shares

any other Equity Securities of SPAC, collectively the “New Securities”), then, in each case, such New Securities acquired or purchased by Sponsor shall be subject to the terms of this Sponsor Agreement to the same extent as if they
constituted Founder Shares or Private Placement Warrants owned by Sponsor as of the date hereof. Nothing in this Section 22 shall limit restrict or modify any liability or other obligation of SPAC under the Merger
Agreement. 


  

	23)	 Each of the parties hereto agrees to execute and deliver hereafter any further document, agreement or
instrument of assignment, transfer or conveyance as may be necessary or desirable to effectuate the purposes hereof and as may be reasonably requested in writing by another party hereto.
