 Ladies and Gentlemen: 

In connection with the proposed business combination (the “Transaction”) between SC Health Corporation, a Cayman Islands

Islands with limited liability (“HoldCo”) and Rockley Mergersub Limited, an exempted company incorporated in the Cayman Islands with limited liability and a direct wholly owned subsidiary of HoldCo, SC Health is seeking commitments

“Offering”). In connection therewith, the undersigned subscriber (“Subscriber”), SC Health and HoldCo agree in this subscription agreement (this “Subscription Agreement”) as follows:

irrevocably subscribes for and agrees to purchase from HoldCo such number of Ordinary Shares as is set forth on the signature page of this Subscription Agreement (the “Shares”) at the Purchase Price per Share and on the terms
provided for herein. 
 SC Health and HoldCo have entered into separate subscription agreements (the “Other Subscription

meaning of Rule 501(a)(1), (2), (3), (7) or (8) under the Securities Act) (each, an “Other Subscriber”), pursuant to which such investors have agreed to purchase Ordinary Shares on the Closing Date and the aggregate gross
proceeds from the securities to be sold by HoldCo pursuant to this Subscription Agreement and the Other Subscription Agreements equals, as of the date hereof, $150,000,000. 

2. Closing; Delivery of Shares. 

(a) The closing of the sale of Shares contemplated hereby (the “Closing”, and the date that the Closing actually occurs, the
“Closing Date”) is contingent upon the substantially concurrent consummation of the Transaction (the “Transaction Closing”). The Closing shall occur on the date of the Transaction Closing, and immediately prior to,
the Merger Effective Time (as defined in the Transaction Agreement). 












 (b) HoldCo shall provide written notice (which may be via email) to the Subscriber (the
“Closing Notice”) that HoldCo reasonably expects the Transaction Closing to occur on a date specified in the notice (the “Scheduled Closing Date”) that is not less than three (3) business days from the date of
the Subscriber’s receipt of the Closing Notice, which Closing Notice shall contain HoldCo’s wire instructions for an escrow account (the “Escrow Account”) established by HoldCo with a third party escrow agent (the
“Escrow Agent”) to be identified in the Closing Notice. At least two (2) business days prior to the Scheduled Closing Date, the Subscriber shall deliver to the Escrow Account the aggregate Purchase Price for the Shares
subscribed by wire transfer of United States dollars in immediately available funds. Upon the Closing, HoldCo shall provide instructions to the Escrow Agent to release the funds in the Escrow Account to HoldCo against delivery to the Subscriber of
the Shares, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), in book-entry form as set forth in Section 2(c) below. If this Subscription
Agreement is terminated prior to the Closing and any funds have already been sent by the Subscriber to the Escrow Account, then promptly (but in no event later than five (5) business days after the Scheduled Closing Date specified in the
Closing Notice) after such termination, HoldCo will instruct the Escrow Agent to promptly return such funds to the Subscriber. 
 (c) On the
Closing Date, promptly after the Closing, HoldCo shall deliver (or cause the delivery of) the Shares in book-entry form with restrictive legends in the amount as set forth on the signature page to the Subscriber as indicated on the signature page.

threatening of any proceedings for any of such purposes, shall have occurred; 
 (ii) no governmental authority of competent jurisdiction
shall have rendered, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and which then makes the consummation of the transactions contemplated
hereby illegal or then restrains or prohibits the consummation of the transactions contemplated hereby; and 
 (iii) all material conditions
precedent to the Transaction Closing set forth in the Transaction Agreement shall have been satisfied or waived (other than those conditions which, by their nature, are to be satisfied at the Transaction Closing). 

(b) The obligations of SC Health and HoldCo to consummate the Closing are also subject to the satisfaction or valid waiver by SC Health and
HoldCo of the additional conditions that, on the Closing Date:

 3 













 
instrument to which SC Health or HoldCo or any of their respective subsidiaries is a party or by which SC Health or HoldCo or any of their respective subsidiaries is bound or to which any of the
property or assets of SC Health or HoldCo is subject, which would have a material adverse effect on the business, properties, financial condition, stockholders’ equity or results of operations of SC Health or HoldCo (a “Material Adverse

warranties set forth in Section 5, in connection with the offer, sale and delivery of the Shares in the manner contemplated by this Subscription Agreement, it is not necessary to register the Shares under the Securities
Act.

HoldCo security or solicited any offers to buy any security under circumstances that would adversely affect reliance by HoldCo on either Regulation S under the Securities Act or Section 4(a)(2) of the Securities Act for the exemption from
registration for the transactions contemplated hereby or would require registration of the issuance of the Shares under the Securities Act. 

(i) There are no Other Subscription Agreements, side letter agreements or other agreements or understandings (including written summaries of
any oral understandings) with any Other Subscriber that include terms and conditions that are materially more advantageous to any such Other Subscriber (as compared to Subscriber) containing any of the following: (i) any rights or benefits
granted to an Other Subscriber in connection with such Other Subscriber’s compliance with any law, regulation or policy specifically applicable to such Other Subscriber or in connection with the taxable status of an Other Subscriber,

true, correct and complete copy of each form, report, statement, schedule, prospectus, proxy, registration statement and other documents filed by SC Health with the SEC prior to the date of this Subscription Agreement (the “SEC

Subscriber’s professional advisor(s), if any, have had the full opportunity to ask SC Health’s and the Target’s management questions, receive such answers and obtain such information as the Subscriber and such Subscriber’s
professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares. The Subscriber has conducted its own investigation of SC Health, HoldCo, the Target and the Shares and the Subscriber has made its own

(f) The Subscriber became aware of this Offering of the Shares solely by means of direct contact between the Subscriber and SC Health, HoldCo,
the Placement Agents or a representative of SC Health, HoldCo or the Placement Agents, and the Shares were offered to the Subscriber solely by direct contact between the Subscriber and SC Health, HoldCo, the Placement Agents or a representative of
SC Health, HoldCo or the Placement Agents. The Subscriber acknowledges that SC Health and HoldCo each represents and warrants severally (and not jointly and severally), as to itself only, that the Shares (i) were not offered by any form of
general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. Neither the Subscriber, nor any of
its directors, officers, employees, agents, stockholders or partners has either directly or indirectly, including through a broker or finder, (i) to its knowledge, engaged in any general solicitation, or (ii) published any advertisement in
connection with the Offering. 
 (g) The Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase
and ownership of the Shares, including those set forth in the Disclosure Documents and in SC Health’s filings with the SEC. The Subscriber is able to fend for itself in the transactions contemplated herein and has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares, and the Subscriber has sought such accounting, legal and tax advice as the Subscriber has considered necessary to make an informed
investment decision. 
 (h) Alone, or together with any professional advisor(s), the Subscriber has adequately analyzed and fully considered
the risks of an investment in the Shares and determined that the Shares are a suitable investment for the Subscriber and that the Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of the
Subscriber’s investment in HoldCo. The Subscriber acknowledges specifically that a possibility of total loss exists. 
 (i) In making
its decision to purchase the Shares, the Subscriber has relied solely upon independent investigation made by the Subscriber and the representations and warranties of SC Health and HoldCo set forth herein. Without limiting the generality of the

incorporation or formation. 
 (l) The execution, delivery and performance by the Subscriber of this Subscription Agreement are within the

court or other tribunal or of any governmental commission or agency, or any agreement or other undertaking, to which the Subscriber is a party or by which the Subscriber is bound, and, if the Subscriber is not an individual, will not violate any
provisions of the Subscriber’s charter documents, including its incorporation or formation papers, bylaws, indenture of trust or partnership or operating agreement, as may be applicable. The signature on this Subscription Agreement is genuine,
and the signatory, if the Subscriber is an individual, has legal competence and capacity to execute the same or, if the Subscriber is not an individual the signatory has been duly authorized to execute the same, and this Subscription Agreement
constitutes a legal, valid and binding obligation of the Subscriber, enforceable against the Subscriber in accordance with its terms. 
 (m)
Neither the due diligence investigation conducted by the Subscriber in connection with making its decision to acquire the Shares nor any representations and warranties made by the Subscriber herein shall modify, amend or affect the Subscriber’s
right to rely on the truth, accuracy and completeness of SC Health’s and HoldCo’s representations and warranties contained herein. 

(n) The Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by

prohibited by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (iii) a non-U.S. shell bank or providing banking
services indirectly to a non-U.S. shell bank (collectively, a “Prohibited Investor”). The Subscriber agrees to provide law enforcement agencies, if requested thereby, such records as required
by applicable law, provided that the Subscriber is permitted to do so under applicable law. If the Subscriber is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of
2001, and its implementing regulations (collectively, the “BSA/PATRIOT Act”), the Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. To the extent
required, it maintains policies and procedures reasonably designed for the screening of its investors against the OFAC sanctions programs, including the OFAC List. To the extent required, it maintains policies and procedures reasonably designed to
ensure that the funds held by the Subscriber and used to purchase the Shares were legally derived. 
 (o) As of the date hereof and at the
Closing, neither the Subscriber, nor, to the extent it has them, any of its direct beneficial owners or (only so far as the Subscriber is aware) its indirect beneficial owners or its directors, affiliates or executive officers (collectively with the
Subscriber, the “Covered Persons”), are subject to any of the “Bad Actor” disqualifications described in Rule 506(d) under the Securities Act (a “Disqualification Event”), except for a Disqualification
Event covered by Rule 506(d)(2) or (d)(3). The Subscriber has exercised reasonable care to determine whether any Covered Person is subject to a Disqualification Event. The acquisition of Shares by the Subscriber will not subject SC Health or HoldCo
to any Disqualification Event. 

  
 7 













 (p) Subscriber is not currently (and at all times through Closing will refrain from being or
becoming) a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any successor provision), other than with those
persons or entities who may be deemed affiliates or control persons, acting for the purpose of acquiring, holding or disposing of or taking any other action relating to the equity securities of the Issuer (within the meaning of Rule 13d-5(b)(1) under the Exchange Act). 
 (q) No foreign person (as defined in 31 C.F.R. Part 800.224) in
which the national or subnational governments of a single foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in HoldCo as a result of the purchase and sale of Shares hereunder such
that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over HoldCo from and after the Closing as
a result of the purchase and sale of Shares hereunder. 
 (r) No disclosure or offering document has been prepared by the Placement Agents in
connection with the offer and sale of the Shares. The Placement Agents and each of their respective members, directors, officers, employees, representatives and controlling persons have made no independent investigation with respect to HoldCo, SC
Health, the Target, any of their respective businesses, or the Shares or the accuracy, completeness or adequacy of any information supplied to the Subscriber by SC Health and/or HoldCo. In connection with the issue and purchase of the Shares, the
Placement Agents have not acted as the Subscriber’s financial advisor or fiduciary. 
 (s) The Subscriber acknowledges its obligations
under applicable securities laws with respect to the treatment of non-public information relating to SC Health and HoldCo. 

6. Registration Rights. HoldCo agrees that, within thirty (30) calendar days after the Transaction Closing, HoldCo
will file with the SEC (at HoldCo’s sole cost and expense) a registration statement registering the resale of the Shares (the “Registration Statement”), and HoldCo shall use its commercially reasonable efforts to have the
Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) ninety (90) calendar days after the filing thereof (or one hundred and twenty (120) calendar days after the
filing thereof in the event the SEC reviews and has written comments to the Registration Statement), and (ii) the tenth (10th) business day after the date HoldCo is notified in writing by the SEC that the Registration Statement will not be
“reviewed” or will not be subject to further review. HoldCo will provide a draft of the Registration Statement to the Subscriber for review at least three (3) business days in advance of the filing the Registration Statement, and
shall advise the Subscriber upon the Registration Statement being declared effective by the SEC. If the SEC prevents HoldCo from including any or all of the Shares proposed to be registered under the Registration Statement due to limitations on the
use of Rule 415 under the Securities Act for the resale of the Shares by the Holders or otherwise, HoldCo shall use its best efforts to ensure that the SEC determines that (1) the offering contemplated by the Registration Statement is a bona
fide secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 of the Securities Act and (2) the Subscriber is not a statutory underwriter. If HoldCo is unsuccessful in the efforts described in the
preceding sentence then (i) HoldCo shall cause such Registration Statement to register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the SEC and (ii) the Subscriber shall have an
opportunity to withdraw its Shares. In such event, the number of Shares to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders. HoldCo agrees that HoldCo will
cause such Registration Statement or another registration statement (which may be a 

  
 8 













 
“shelf” registration statement) to remain effective until the earlier of (i) two years from the issuance of the Shares, (ii) the date on which the Subscriber ceases to hold
the Shares covered by such Registration Statement or any such other registration statement, or (iii) on the first date on which the Subscriber can sell all of its Shares under Rule 144 of the Securities Act without limitation as to the manner
of sale or the amount of such securities that may be sold. The Subscriber agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 of the Exchange Act, of the Shares to HoldCo
(or its successor) upon request to assist HoldCo in making the determination described above. HoldCo’s obligations to include the Shares in the Registration Statement or any such other registration statement are contingent upon the Subscriber
furnishing in writing to HoldCo such information regarding the Subscriber, the securities of HoldCo held by the Subscriber and the intended method of disposition of the Shares as shall be reasonably requested by HoldCo to effect the registration of
the Shares, and shall execute such documents in connection with such registration as HoldCo may reasonably request that are customary of a selling stockholder in similar situations; provided that, in connection therewith, the undersigned shall not
be required to enter into any lock-up or similar arrangement or otherwise be subject to any contractual restrictions with HoldCo on the ability to transfer the Shares. HoldCo may delay filing, delay
effectiveness or suspend the use of any such registration statement if it determines that (i) the financial statements included in such registration statement are required to be updated in order to comply with Regulation S-X age of financial statement requirements or (ii) in order for such registration statement to not contain a material misstatement or omission of a material fact, an amendment thereto or a supplement to the
related prospectus would be needed, or if such filing or use could materially affect a bona fide business or financing transaction of HoldCo or would require premature disclosure of information that could materially adversely affect HoldCo (each
such circumstance, a “Suspension Event”); provided, however, that HoldCo may not delay or suspend any such registration statement on more than two (2) occasions or for more than 60 consecutive calendar days, or more than 90
total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from HoldCo of the happening of any Suspension Event during the period that the Registration Statement or any such other registration statement is
effective or if as a result of a Suspension Event the Registration Statement or any such other registration statement or related prospectus contains any untrue statement of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the related prospectus), not misleading, the Subscriber agrees that it will (i) immediately discontinue offers and
sales of the Shares under the Registration Statement or any such other registration statement until the Subscriber receives (A) (x) copies of a supplemental or amended prospectus that corrects the misstatement(s) or omission(s) referred to
above and (y) notice that any post-effective amendment has become effective or (B) notice from HoldCo that it may resume such offers and sales, and (ii) maintain the confidentiality of any information included in such written notice
delivered by HoldCo unless otherwise required by applicable law. If so directed by HoldCo, the Subscriber will deliver to HoldCo or destroy all copies of the prospectus covering the Shares in the Subscriber’s possession; provided, however, that
this obligation to deliver or destroy all copies of the prospectus covering the Shares shall not apply to (i) the extent the Subscriber is required to retain a copy of such prospectus (A) in order to comply with applicable legal,
regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention policy or (ii) copies stored electronically on archival servers as a
result of automatic data back-up. 
 HoldCo shall, if requested by Subscriber to (i) cause the
removal of the restrictive legends from any Shares while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act and (ii) cause its legal counsel to deliver an
opinion, if necessary, to HoldCo’s transfer agent in connection with the removal of such restrictive legends promptly after the effectiveness date of the applicable registration statement, in each case upon the receipt of customary
representations and other documentation from the Subscriber that is necessary to establish that restrictive legends are no longer required as reasonably requested by HoldCo, its counsel or transfer agent. HoldCo agrees that following the relevant
effectiveness date and the delivery by the undersigned to HoldCo 

  
 9 













 
or the transfer agent of a certificate representing Shares issued with a restrictive legend, it will deliver or cause to be delivered to such Subscriber a certificate representing such Shares
that is free from all restrictive and other legends. Certificates for Shares subject to legend removal hereunder shall be transmitted by the transfer agent to the undersigned by crediting the account of the undersigned’s prime broker with the
Depository Trust Company System as directed by such Subscriber. HoldCo shall pay all transfer agent fees (including, without limitation, any fees required for same-day processing of any instruction letter
delivered by HoldCo and any exercise notice delivered by the undersigned), stamp taxes and other taxes and duties levied in connection with the delivery of any Shares to the undersigned other than income and capital gains taxes of the undersigned
that may be incurred in connection with the transactions contemplated hereby. The Subscriber agrees with HoldCo that it will sell any Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus
delivery requirements, or an exemption therefrom, and that if Shares are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive
legend from certificates representing Shares as set forth in this Section 6 is predicated upon HoldCo’s reliance upon this understanding. 

HoldCo shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a
seller under the Registration Statement), and any of its respective officers, directors, agents, partners, members, stockholders, affiliates, managers, investment advisers and employees, and each person who controls Subscriber (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against any and all
out-of-pocket losses, claims, damages, liabilities, costs (including, without limitation, reasonable external attorneys’ fees and expenses incurred in connection
with defending or investigating any such action or claim) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to
state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading,
except insofar as and to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding the Subscriber furnished in writing to HoldCo by such Subscriber
expressly for use therein or such Subscriber has omitted a material fact from such information or otherwise violated the Securities Act, the Exchange Act or any state securities law or any rule or regulation thereunder; provided, however, that the
indemnification contained in this Section 6 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of HoldCo (which consent shall not be unreasonably withheld, conditioned or delayed), nor
shall HoldCo be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished by such Subscriber, (B) in connection with any
failure of such person to deliver or cause to be delivered a prospectus made available by HoldCo in a timely manner, (C) as a result of offers or sales effected by or on behalf of any person by means of a “free writing prospectus” (as
defined in Rule 405 under the Securities Act) that was not authorized in writing by HoldCo, or (D) in connection with any offers or sales effected by or on behalf of such Subscriber in violation of Section 6 hereof. HoldCo shall notify the
Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6 of which HoldCo is aware. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Securities by Subscriber or any other Holder.

 7. Termination. This Subscription Agreement shall terminate and be void
and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of: (a) the mutual written
agreement of each of the parties hereto to terminate this Subscription Agreement; (b) such date and time as the Transaction Agreement is terminated in accordance with its terms; or (c) written notice by either party to the other party to
terminate this Subscription Agreement if the transactions contemplated by this Subscription Agreement are not consummated on or prior to December 31, 2021; provided that (i) nothing herein will relieve any party from liability for
any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. SC Health and shall notify the Subscriber of the
termination of the Transaction Agreement promptly after the termination of such agreement and (ii) the provisions of Sections 8 through 10 of this Subscription Agreement will survive any termination of this Subscription Agreement
and continue indefinitely. 
 8. Trust Account Waiver. The Subscriber hereby represents and warrants that it has read
the Prospectus and understands that SC Health has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and the overallotment shares acquired by its
underwriters and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of SC Health’s public stockholders (including overallotment shares acquired by SC
Health’s underwriters, the “Public Stockholders”), and that, except as otherwise described in the Prospectus, SC Health may disburse monies from the Trust Account only: (a) to the Public Stockholders in the event they
elect to redeem their SC Health shares in connection with the consummation of SC Health’s initial business combination (as such term is used in the Prospectus, the “Business Combination”) or in connection with an extension of
its deadline to consummate a Business Combination, (b) to the Public Stockholders if SC Health fails to consummate a Business Combination within 21 months after the closing of the IPO, which is subject to extension by amendment to SC
Health’s organizational documents, (c) with respect to any interest earned on the amounts held in the Trust Account, amounts necessary to pay for any franchise and income tax obligations and up to $100,000 in dissolution expenses, or
(d) to SC Health after or concurrently with the consummation of a Business Combination. For and in consideration of SC Health entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the Subscriber hereby agrees on behalf of itself and its affiliates that, notwithstanding anything to the contrary in this Subscription Agreement, neither the Subscriber nor any of its affiliates do now or shall at
any time hereafter have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make any claim against the Trust Account (including any distributions therefrom), regardless of whether
such claim arises as a result of, in connection with or relating in any way to, this Subscription Agreement, the Transaction or any proposed or actual business relationship between SC Health or its Representatives, on the one hand, and the
Subscriber or its Representatives, on the other hand, or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (collectively, the “Released Claims”);
provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with its rights as a Public Stockholder in respect of shares of SC
Health acquired by any means other than pursuant to this Subscription Agreement. The Subscriber on behalf of itself and its affiliates hereby irrevocably waives any Released Claims that the Subscriber or any of its affiliates may have against the
Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with SC Health or its Representatives and will not seek recourse against the Trust Account
(including any distributions therefrom) for any reason whatsoever (including for an alleged breach of this Subscription Agreement or any other agreement with SC Health or its affiliates). The Subscriber agrees and acknowledges that such irrevocable
waiver is material to this Subscription Agreement and specifically relied upon by SC Health and its affiliates to induce SC Health to enter in this Subscription Agreement, and the Subscriber further intends and understands such waiver to be valid,
binding and enforceable against the Subscriber and each of its affiliates under applicable law. To the extent the Subscriber or any of its affiliates commences any action or proceeding based upon, in connection with, relating to or arising out of
any matter 

  
 11 













 
relating to SC Health or its Representatives, which proceeding seeks, in whole or in part, monetary relief against SC Health or its Representatives, the Subscriber hereby acknowledges and agrees
that the Subscriber’s and its affiliates’ sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit the Subscriber or its affiliates (or any person claiming on any of their behalves or in
lieu of any of them) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. In the event the Subscriber or any of its affiliates commences any action or proceeding based upon, in
connection with, relating to or arising out of any matter relating to SC Health or its Representatives, which proceeding seeks, in whole or in part, relief against the Trust Account (including any distributions therefrom) or against SC Health or the
Public Stockholders, whether in the form of money damages or injunctive relief, SC Health and its Representatives, as applicable, shall be entitled to recover from the Subscriber and its affiliates the associated legal fees and costs in connection
with any such action in the event SC Health or its Representatives, as applicable, prevails in such action or proceeding. For purposes of this Subscription Agreement, “Representatives” with respect to any person shall mean such
person’s affiliates and its and its affiliate’s respective directors, officers, employees, consultants, advisors, agents and other representatives. Notwithstanding anything to the contrary contained in this Subscription Agreement, the
provisions of this Section 8 shall survive the Closing or any termination of this Subscription Agreement and last indefinitely. 

9. Miscellaneous. 

(a) SC Health shall, no later than 9:00 a.m., New York City time, on the first business day immediately following the date of this Subscription
Agreement, issue one or more press releases or file with the SEC a Current Report on Form 8-K (collectively, the “Signing 8-K”) disclosing all material
terms of the transactions contemplated hereby, the Transaction and any other material, nonpublic information that SC Health or any of its officers, directors, employees or agents (including the Placement Agents) has provided to the undersigned at
any time prior to the filing of the Signing 8-K. From and after the issuance of the Signing 8-K, the undersigned shall not be in possession of any material, non-public information received from SC Health or any of its officers, directors, employees or agents (including the Placement Agents) and the Subscriber shall no longer be subject to any confidentiality or similar
obligations under any current agreement, whether written or oral with SC Health, the Placement Agents, or any of their respective affiliates. Except with the express written consent of the Subscriber and unless prior thereto the Subscriber shall
have executed a written agreement regarding the confidentiality and use of such information, neither SC Health nor Holdco shall, and shall cause its officers, directors, employees and agents, not to, provide Subscriber with any material, non-public information regarding SC Health, Holdco or the Transaction from and after the filing of the Signing 8-K. 

(b) Neither this Subscription Agreement nor any rights that may accrue to the Subscriber hereunder (other than the Shares acquired hereunder,
if any, subject to applicable securities laws) may be transferred or assigned by the Subscriber without the prior written consent of SC Health and HoldCo, and any purported transfer or assignment without such consent shall be null and void ab
initio. 
 (c) HoldCo and SC Health may request from the Subscriber such additional information as SC Health and/or HoldCo may deem necessary
to evaluate the eligibility of the Subscriber to acquire the Shares, and the Subscriber shall provide such information to SC Health and HoldCo upon such request provided that SC Health and HoldCo keep any such information so provided confidential,
it being understood by the Subscriber that HoldCo and SC Health may without any liability hereunder reject the Subscriber’s subscription prior to the Closing Date in the event the Subscriber fails to provide such additional information
requested by SC Health and HoldCo to evaluate the Subscriber’s eligibility or SC Health and HoldCo determines that the Subscriber is not eligible. 

  
 12 













 (d) The Subscriber acknowledges that SC Health, HoldCo, the Placement Agent, the Target and
others will rely on the acknowledgments, understandings, agreements, representations and warranties of the Subscriber contained in this Subscription Agreement. Prior to the Closing, the Subscriber agrees to promptly notify SC Health and HoldCo if
any of the acknowledgments, understandings, agreements, representations and warranties set forth herein are no longer accurate. The Subscriber agrees that the purchase by the Subscriber of Shares from HoldCo will constitute a reaffirmation of the
acknowledgments, understandings, agreements, representations and warranties herein (as modified by any such notice) by the Subscriber as of the time of such purchase. The Subscriber acknowledges and agrees that each of the Placement Agents and the
Target and their respective affiliates is a third-party beneficiary of the representations, warranties and covenants of the Subscriber contained in Section 5 of this Subscription Agreement, and that the Target is otherwise an express third
party beneficiary of this Subscription Agreement, entitled to enforce the terms hereof against Subscriber as if it were an original party hereto. Except as expressly set forth herein, this Subscription Agreement shall not confer any rights or
remedies upon any person other than the parties hereto, and their respective successor and assigns. 
 (e) Each of SC Health and HoldCo is
entitled to rely upon this Subscription Agreement and is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters
covered hereby to the extent required by law or regulatory bodies. Neither party shall issue any press release or make any other similar public statement with respect to the transactions contemplated hereby without the prior written consent of SC
Health and HoldCo (such consent not to be unreasonably withheld or delayed). 
 (f) All the agreements, representations and warranties made
by each party hereto in this Subscription Agreement shall survive the Closing. 
 (g) This Subscription Agreement may not be amended,
modified, waived or terminated except by an instrument in writing, signed by the party against whom enforcement of such modification, waiver, or termination is sought. 

(h) This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations
and warranties, both written and oral, among the parties, with respect to the subject matter hereof (other than any confidentiality agreement entered into by SC Health and/or HoldCo and the Subscriber in connection with the Offering). 

(i) This Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors,
administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors,
administrators, successors, legal representatives and permitted assigns. 
 (j) If any provision of this Subscription Agreement shall be
invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect. 

(k) This Subscription Agreement may be executed in one or more counterparts (including by facsimile or electronic mail or in .pdf) and by
different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement. 

  
 13 













 (l) The parties hereto agree that irreparable damage would occur in the event that any of
the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches
of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. 

(m) THIS SUBSCRIPTION AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICTS OF LAWS THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER STATE. EACH PARTY HERETO HEREBY WAIVES ANY RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY LITIGATION PURSUANT TO THIS SUBSCRIPTION AGREEMENT
AND THE TRANSACTIONS CONTEMPLATED HEREBY. 
 (n) All notices, consents, waivers and other communications hereunder shall be in writing
and shall be deemed to have been duly given (i) when delivered in person, (ii) when delivered by facsimile or email, with affirmative confirmation of receipt, (iii) one business day after being sent, if sent by reputable,
internationally recognized overnight courier service or (iv) three (3) business days after being mailed, if sent by registered or certified mail, prepaid and return receipt requested, in each case to the applicable party at the following

	Notice to the Subscriber shall be given to the address underneath the Subscriber’s name on the signature page hereto.

 (o) The headings set forth in this Subscription Agreement are for convenience of reference only and shall not
be used in interpreting this Subscription Agreement. In this Subscription Agreement, unless the context otherwise requires: (i) whenever required by the context, any pronoun used in this Subscription Agreement shall include the corresponding
masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including” (and with correlative meaning “include”) means including without limiting the
generality of any description preceding or succeeding such term and shall be deemed in each case to be followed by the words “without limitation”; and (iii) the words “herein”, “hereto” and “hereby” and
other words of similar import in this Subscription Agreement shall be deemed in each case to refer to this Subscription Agreement as a whole and not to any particular portion of this Subscription Agreement. As used in this Subscription Agreement,
the term: (x) “business day” shall mean any day other than a Saturday, Sunday or a legal holiday on which commercial banking institutions in New York, New York (or as such term is used in Section 6 hereof, Washington, D.C.) are
authorized to close for business (excluding as a result of “stay at home”, “shelter-in-place”,
“non-essential employee” or any other similar orders or restrictions or the closure of any physical branch locations at the direction of any governmental authority so long as the electronic funds
transfer systems, including for wire transfers, of commercially banking institutions in New York, New York are generally open for use by customers on such day); (y) “person” shall refer to any individual, corporation, partnership, trust,
limited liability company or other entity or association, including any governmental or regulatory body, whether acting in an individual, fiduciary or any other capacity; and (z) “affiliate” shall mean, with respect to any specified
person, any other person or group of persons acting together that, directly or indirectly, through one or more intermediaries controls, is controlled by or is under common control with such specified person (where the term “control” (and
any correlative terms) means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of such person, whether through the ownership of voting securities, by contract or otherwise). For the
avoidance of doubt, any reference in this Subscription Agreement to an affiliate of the SC Health will include SC Health’s sponsor, SC Health Holdings Limited. 

(p) At Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the parties may
reasonably deem practical and necessary in order to consummate the Offering as contemplated by this Subscription Agreement. 
 10.
Non-Reliance and Exculpation. The Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person other than the
statements, representations and warranties contained in this Subscription Agreement in making its investment or decision to invest in HoldCo. The Subscriber agrees that neither (i) any other purchaser pursuant to other subscription agreements
entered into in connection with the Offering (including the controlling persons, members, officers, directors, partners, agents, or employees of any such other purchaser) nor (ii) each Placement Agent, each of their respective affiliates or any
of their respective affiliates’ respective control persons, officers, directors or employees, shall be liable to the Subscriber pursuant to this Subscription Agreement, the negotiation hereof or thereof or its subject matter, or the
transactions contemplated hereby or thereby, including, without limitation, for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares or with respect to any claim (whether in
tort, contract or otherwise) for breach of this Subscription Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies,
misstatements or omissions with respect to any information or materials of any kind furnished.
