Re: Amended and Restated Sponsor Agreement 
 Ladies and
Gentlemen: 
 This letter (this “Sponsor Agreement”) is being delivered to you in connection with that certain Agreement
and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), by and among LumiraDx Limited, a Cayman Islands exempted company limited by shares with company number 314391 (“LumiraDx”), LumiraDx Merger
Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of LumiraDx (“Merger Sub”, and collectively with LumiraDx, the “Company”), and CA Healthcare Acquisition Corp., a Delaware corporation
(“CAH”), and hereby amends and restates in its entirety that certain letter, dated January 25, 2021, from CA Healthcare Sponsor LLC (the “Sponsor”) and each of the undersigned individuals, each of whom is a
member of CAH’s board of directors and/or management team (each, an “Insider” and collectively, the “Insiders”) to CAH (the “Prior Letter Agreement”). Certain capitalized terms used herein are
defined in paragraph 11 hereof. Capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Merger Agreement. 

In order to induce the Company and CAH to enter into the Merger Agreement and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Sponsor and each of the Insiders, hereby severally (and not jointly and severally) agrees with CAH and, at all times prior to any valid termination of the Merger Agreement, the Company as follows: 

1. The Sponsor and each Insider hereby unconditionally and irrevocably agrees: (i) that at any duly called meeting of the stockholders of
CAH (or any adjournment or postponement thereof), and in any action by written consent of the stockholders of CAH requested by CAH’s board of directors or undertaken in furtherance of the transactions contemplated by the Merger Agreement (the
“Transactions”), the Sponsor and each such Insider shall, if a meeting is held, appear at the meeting, in person or by proxy, or otherwise cause all of its, his or her Shares to be counted as present thereat for purposes of
establishing a quorum, and it shall vote or consent (or cause to be voted or consented), in person or by proxy, all of its, his or her Shares (a) in favor of the adoption of the Merger Agreement and approval of the Transactions (and any actions
required in furtherance thereof), (b) against any action, proposal, transaction or agreement that would reasonably be expected to result in a breach of any representation, warranty, covenant, obligation or agreement of CAH contained in the Merger
Agreement, (c) in favor of any other proposals set forth in CAH’s proxy statement to be filed by CAH with the SEC relating to the Transactions (including any proxy supplements thereto, the “Proxy Statement”) and
(d) except as set forth in the Proxy Statement, against the following actions or proposals: (I) any CAH Alternative Transaction or any proposal in opposition to approval of the Merger Agreement or in competition with or inconsistent with
the Merger Agreement; and (II)(A) any change in the present capitalization of CAH or any amendment of the Charter (as defined below), except to the extent expressly contemplated by the Merger Agreement, (B) any liquidation, dissolution or
other change in CAH’s corporate structure or business, (C) any action, proposal, transaction or agreement that would result in a breach in any material respect of any covenant, representation or warranty or other obligation or agreement of
the Sponsor or such Insider under this Sponsor Agreement, 
  












 or (D) any other action or proposal involving CAH or any of its subsidiaries that is intended, or would
reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect the Transactions and (ii) not to redeem, elect to redeem or tender or submit any of the Shares owned by it, him or her for redemption in connection
with such stockholder approval or proposed Business Combination, or in connection with any vote to amend the Charter. Prior to any valid termination of the Merger Agreement, (x) the Sponsor and each Insider shall take, or cause to be taken, all
actions and to do, or cause to be done, all things reasonably necessary under applicable Laws to consummate the Transactions and the other transactions contemplated by the Merger Agreement and on the terms and subject to the conditions set forth
therein, and (y) the Sponsor and each Insider shall be bound by and comply with Sections 6.3 (Access to Information; Confidentiality) and 6.4 (Exclusivity) of the Merger Agreement (and any relevant definitions contained in any such Sections) as
if such person were a signatory to the Merger Agreement with respect to such provisions. If CAH seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider agrees that it, he or she will not sell
or tender any Shares owned by it, him or her in connection therewith. The obligations of the Sponsor and the Insiders specified in this paragraph 1 shall apply whether or not the Merger, any of the Transactions or any action described above is
recommended by CAH’s board of directors. 
 2. The Sponsor and each Insider hereby agrees that in the event that CAH fails to consummate
a Business Combination within 24 months from the closing of the Public Offering (the “Completion Window”), or such later period approved by CAH’s stockholders in accordance with CAH’s amended and restated certificate
of incorporation (the “Charter”), the Sponsor and each Insider shall take all reasonable steps to cause CAH to (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not
more than 10 Business Days thereafter, subject to lawfully available funds therefor, redeem 100% of the Common Stock sold as part of the Units in the Public Offering (the “Offering Shares”), at a
per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the Trust Account and not previously
released to CAH to pay its taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Stockholders’ rights as
stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (c) as promptly as reasonably possible following such redemption, subject to the approval of CAH’s remaining
stockholders and CAH’s board of directors, dissolve and liquidate, subject in each case to CAH’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider
agrees not to propose any amendment to the Charter to modify (i) the substance or timing of the ability of holders of Offering Shares to seek redemption in connection with a Business Combination, (ii) certain amendments to the Charter
prior to the completion of a Business Combination or (iii) (A) CAH’s obligation to redeem 100% of the Offering Shares if CAH does not complete a Business Combination within the Completion Window or (B) any other provisions
relating to stockholders’ rights or pre-initial Business Combination activity, unless CAH provides the Public Stockholders with the opportunity to redeem their shares of Common Stock upon approval of any
such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously
released to CAH to pay its taxes, divided by the number of then outstanding Offering Shares. 
 The Sponsor and each Insider acknowledges
that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of CAH as a result of any liquidation of CAH with respect to the Founder Shares held by it, him or her. The
Sponsor and each Insider hereby further waive, with respect to any shares of Common Stock held by it, him or her, if any, whether acquired now or hereafter, any redemption rights it, he or she may have in connection with the consummation of a
Business Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or a stockholder vote to approve an 

  
 2 













 
amendment to the Charter to modify (I) the substance or timing of the ability of holders of Offering Shares to seek redemption in connection with a Business Combination or
(II) (A) CAH’s obligation to redeem 100% of the Offering Shares if CAH does not complete a Business Combination within the Completion Window or (B) any other provisions relating to stockholders’ rights or pre-initial Business Combination activity, unless CAH provides the Public Stockholders with the opportunity to redeem their shares of Common Stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to CAH to pay its
taxes, divided by the number of then outstanding Offering Shares, or (III) in the context of a tender offer made by CAH to purchase shares of Common Stock (although the Sponsor, the Insiders and their respective affiliates shall be entitled to
redemption and liquidation rights with respect to any Offering Shares it or they hold if CAH fails to consummate a Business Combination within the time period set forth in the Charter). 

3. Without limiting their obligations under paragraph 6 below, during the period commencing on the date hereof and ending on the earlier of
(a) the valid termination of the Merger Agreement or (b) the Closing, the Sponsor and each Insider shall not, without the prior written consent of the Company, Transfer any Units, shares of Capital Stock, warrants (each, a
“Warrant”) to purchase Capital Stock or any securities convertible into, or exercisable, or exchangeable for, shares of Capital Stock owned by it, him or her. In the event that (i) any shares of Capital Stock, Warrants or other
equity securities of CAH are issued to the Sponsor or any Insider after the date hereof pursuant to any stock dividend, stock split, recapitalization, reclassification, combination or exchange of shares of Capital Stock of, on or affecting the
shares of Capital Stock owned by the Sponsor or any Insider or otherwise, (ii) the Sponsor or any Insider purchases or otherwise acquires beneficial ownership of any shares of Capital Stock, Warrants or other equity securities of CAH after the
date hereof or (iii) the Sponsor or any Insider acquires the right to vote or share in the voting of any shares of Capital Stock, Warrants or other equity securities of CAH after the date hereof (such shares of Capital Stock, Warrants or other
equity securities of CAH described in clauses (i), (ii) and (iii), the “New Shares”), then such New Shares acquired or purchased by the Sponsor or any Insider shall be subject to the terms of this paragraph 3 and paragraph 1
above to the same extent as if they constituted the Capital Stock or Warrants owned by the Sponsor or any Insider as of the date hereof. 

4. In the event of the liquidation of the Trust Account upon the failure of CAH to consummate its initial Business Combination within the time
period set forth in the Charter, the Sponsor (the “Indemnitor”) agrees to indemnify and hold harmless CAH against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or
other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened) to which CAH may become subject as a result of any claim by (i) any third party for services rendered or products
sold to CAH or (ii) any prospective target business with which CAH has entered into a written letter of intent, confidentiality or other similar agreement for a Business Combination (a “Target”); provided, however, that such
indemnification of CAH by the Indemnitor shall (x) apply only to the extent necessary to ensure that such claims by a third party or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per
Offering Share and (ii) the actual amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Offering Share is then held in the Trust Account due to reductions in the
value of the trust assets, less interest earned on the Trust Account which may be withdrawn to pay taxes, (y) not apply to any claims by a third party or a Target which executed a waiver of any and all rights to the monies held in the Trust
Account (whether or not such waiver is enforceable) and (z) not apply to any claims under CAH’s indemnity of the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The Indemnitor
shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to CAH if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies CAH in writing that
it shall undertake such defense.

 5. The Sponsor and each Insider hereby agrees and acknowledges that: (i) CAH and, prior
to any valid termination of the Merger Agreement, the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 6(a), 6(b), 6(c), 6(d), 6(e) and 11, as
applicable, of this Sponsor Agreement, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any
other remedy that such party may have in law or in equity, in the event of such breach. 
 6. 

(a) The Sponsor and each Insider agrees that it, he or she shall not Transfer, other than as provided for in Article 6.13 of the Company
Articles, (i) any Founder Shares (or shares of Common Stock issuable upon conversion thereof) or (ii) any common shares of the Company issued in respect of Forfeited Founder Shares, until the earlier of (A) one year after the
completion of CAH’s initial Business Combination (if the Closing does not occur for any reason (including, without limitation, as a result of the valid termination of the Merger Agreement)) or the Closing, as applicable, or (B) subsequent
to the initial Business Combination (if the Closing does not occur for any reason (including, without limitation, as a result of the valid termination of the Merger Agreement)) (x) if the last reported sale price of the Common Stock equals or
exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least
150 days after CAH’s initial Business Combination (if the Closing does not occur for any reason (including, without limitation, as a result of the valid termination of the Merger Agreement)), or (y) (other than if the Closing occurs)
the date on which CAH completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of CAH’s stockholders having the right to exchange their shares for cash, securities or other property (the
“Founder Shares Lock-up Period”). 
 (b) In the event that the Closing does not
occur for any reason (including, without limitation, as a result of the valid termination of the Merger Agreement), the Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or shares of Common Stock
issued or issuable upon the exercise of the Private Placement Warrants) until 30 days after the completion of a Business Combination (the “Private Placement Warrants Lock-up Period”, and
together with the Founder Shares Lock-up Period, the “Lock-up Periods”). 

(c) Notwithstanding the provisions set forth in paragraphs 3 and 6(a) and (b), (i) upon the valid termination of the Merger Agreement, the
following Transfers of the Founder Shares, the Private Placement Warrants and shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares that are held by the Sponsor, any Insider
or any of their permitted transferees (that have complied with this paragraph 6(c)), are permitted: (A) to CAH’s officers or directors, any affiliates or family members of any of CAH’s officers or directors, any members of the
Sponsor, or any affiliates of the Sponsor; (B) in the case of an individual, transfers by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or
an affiliate of such person, or to a charitable organization; (C) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (D) in the case of an individual, transfers pursuant to a
qualified domestic relations order; (E) transfers by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the securities were originally purchased;
(F) transfers in the event of CAH’s liquidation prior to the completion of an initial Business Combination; (G) transfers by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon
dissolution of the Sponsor; (H) in the event of CAH’s completion of a liquidation, merger, stock exchange, reorganization or other similar transaction which results in all of the Public Stockholders having the right to exchange their
shares of Common Stock for cash, securities or other property subsequent to the completion of the initial Business Combination; (I) to a nominee or custodian of a person or entity to whom a disposition or


  
 4 













 
transfer would be permissible under clauses (A) through (H) above; provided, however, that in the case of clauses (A) through (E) and (I), these permitted
transferees must enter into a written agreement with CAH agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Sponsor Agreement (including provisions relating to voting, the Trust Account and
liquidating distributions) and (ii) during the period commencing on the date hereof and ending on the earlier of (x) the expiration of the Lock-up Periods and (y) the date of any valid
termination of the Merger Agreement, the following Transfers of the Founder Shares, the Private Placement Warrants identified on Annex A as “Locked-Up Warrants”, shares of Common Stock issued
or issuable upon the exercise or conversion of the Private Placement Warrants identified on Annex A as “Locked-Up Warrants” or the Founder Shares, that are held by the Sponsor or any Insider
or any of their permitted transferees (that have complied with this paragraph 6(c)), are permitted; (1) to CAH’s officers or directors, any affiliates or family members of any of CAH’s officers or directors, any member of the Sponsor,
or any affiliates of the Sponsor; (2) in the case of an individual, transfers by gift to a member of one of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or an
affiliate of such person, or to a charitable organization; (3) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of such person; (4) in the case of an individual, transfers pursuant to a
qualified domestic relations order; provided, however, that any permitted transferee must enter into a written agreement with CAH agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this
Sponsor Agreement (including provisions relating to voting, the Trust Account and liquidating distributions). 
 (d) Conversion and
Exchange. As of and conditioned upon the Closing, the Sponsor agrees that all of its Private Placement Warrants shall be converted and exchanged for 405,000 common shares of the Company (the “Warrant Conversion Shares”). The
Sponsor and each Insider agrees that it, he or she shall not Transfer, other than as provided for in Article 6.13 of the Company Articles, any Warrant Conversion Shares until the six month anniversary of the Closing. 

(e) Sponsor Equity Cancellation. In the event that more than fifty percent (50%) of the Class A Common Stock sold in the Public
Offering is redeemed, then an equal percentage of the Founder Shares shall be cancelled prior to giving effect to the CAH Class B Conversion (the “Forfeited Founder Shares”) and accordingly the Company shall have no obligation
under this Sponsor Agreement, the Merger Agreement or any other agreement relating to the Transactions to issue any common shares of the Company in respect of such Forfeited Founder Shares; provided however that for the period from the Closing Date
and up to 31 December 2021 the Company, in its sole discretion, may elect to issue, on the same terms as provided for in the Merger Agreement, common shares of the Company in respect of some or all of the Forfeited Founder Shares to the
Sponsor. For the avoidance of doubt, in the event that fifty percent (50%) or less of the Class A Common Stock sold in the Public Offering is redeemed, no such forfeiture shall occur and the Sponsor shall retain one hundred percent (100%) of
its Founder Shares and be issued one hundred percent (100%) of its entitlement to common shares of the Company pursuant to the terms of the Merger Agreement. By way of illustrative example if 60% of the Class A Common Stock sold in the Public
Offering is redeemed, then the Sponsor shall only receive 1,150,000 common shares in the Company (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like). 

7. The Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in any
securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to CAH (including any such information included in the
Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s background. Each Insider’s questionnaire furnished to CAH is true and accurate in all respects. Each Insider
represents and warrants that: (i) it, he or she is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or
stipulation to desist or refrain from any act or practice 

  
 5 













 
relating to the offering of securities in any jurisdiction; (ii) it, he or she has never been convicted of, or pleaded guilty to, any crime (A) involving fraud, (B) relating to any
financial transaction or handling of funds of another person, or (C) pertaining to any dealings in any securities and it, he or she is not currently a defendant in any such criminal proceeding. 

8. Except as disclosed in the Prospectus, neither the Sponsor nor any officer, director, advisor or any affiliate of the Sponsor or officer,
director or advisor of CAH, shall receive from CAH any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate,
the consummation of the CAH’s initial Business Combination (regardless of the type of transaction that it is). 
 9. Each Insider agrees
that, until the consummation of the Business Combination and for one year thereafter, he or she will keep confidential all confidential, proprietary and non-public information of CAH (whether written, oral or
electronic communications), including without limitation, the names of the targets identified by CAH for a potential Business Combination and any and all information provided by CAH to the Insider regarding such targets. 

10. The Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including, without limitation,
any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Sponsor Agreement and, as applicable, to serve as an officer
and/or a director on the board of directors of CAH.

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 shall be added as a part of this

WAIVER, (C) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY AMONG OTHER THINGS THE MUTUAL WAIVERS IN THIS PARAGRAPH 18(b).

Merger Agreement pursuant to Article 8 thereof (in which case this Sponsor Agreement shall be of no force or effect and shall revert to the Prior Letter Agreement), (ii) the expiration of the Lock-up Periods,
or (iii) the liquidation of CAH; provided, however, that paragraph 4 and paragraph 9 of this Sponsor Agreement shall survive such liquidation for a period of six years; provided, further, that no such termination (including
one that results in a reversion to the Prior Letter Agreement under clause (i)) shall relieve the Sponsor, any Insider or CAH from any liability resulting from a willful breach of this Sponsor Agreement occurring prior to such termination. 

21. Each of the Sponsor and the Insiders hereby represents and warrants (severally and not jointly as to itself, himself or herself only) to
CAH 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 incorporated, formed, organized or constituted, and the
