Section 2.4 hereof, at any time following the Closing and expiration or waiver of any lockup applicable to such Holders party hereto, the Sponsor, MVIL or Holders of a majority in interest of the then-outstanding number of
Registrable Securities (together, the “Demanding Holders”) may make a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be
included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”). The Company shall, within ten (10) days of the Company’s receipt of the Demand

pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five
(5) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written 

  
 5 













 
notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand
Registration and the Company shall effect, as soon thereafter as practicable, but not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities
requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. Under no circumstances shall the Company be obligated to effect more than (i) an aggregate of three (3) Registrations pursuant to a Demand
Registration under this subsection 2.1.1 by Holders of a majority in interest of the then-outstanding number of Registrable Securities, (ii) one (1) Registration pursuant to a Demand Registration under this subsection 2.1.1 by the
Sponsor and (iii) one (1) Registration pursuant to a Demand Registration under this subsection 2.1.1 by MVIL; provided, however, that a Registration shall not be counted for such purposes unless a Form F-1 or any similar long-form registration statement that may be available at such time (“Form F-1”) has become effective and all of the Registrable
Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Form F-1 Registration have been sold, in accordance with Section 3.1 of
this Agreement. 
 2.1.2    Effective Registration. Notwithstanding the provisions of subsection 2.1.1
above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a
Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that if, after such Registration
Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other
governmental agency the Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and

accordingly notify the Company in writing, but in no event later than five (5) days, of such election; and provided, further, that the Company shall not be obligated or required to file another Registration Statement until the
Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated.

Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the
offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such
Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders
proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by
the majority-in-interest of the Demanding Holders initiating the Demand Registration.

 2.1.4    Reduction of Underwritten Offering. If the managing
Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable
Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other Common Shares or other equity securities that the Company desires to sell and the Common Shares, if any, as to which a
Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other shareholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in
the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable,
the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any)
(pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the
Demanding Holders and Requesting Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities;
(ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Registrable Securities of Holders (Pro Rata, based on the respective number of Registrable Securities that each
Holder has so requested) exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1 hereof, without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of
Securities has not been reached under the foregoing clauses (i) and (ii), the Common Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iv) fourth,

pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration prior to the effectiveness of the
Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration. If withdrawn, such Demand Registration shall constitute a Demand Registration under subsection
2.1.1 unless the Demanding Holders or Requesting Holders (if any) reimburse the Company for all Registration Expenses with respect to such withdrawn Demand Registration. Notwithstanding anything to the contrary in this Agreement, the Company
shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5, other than if a Demanding Holder or Requesting Holders (if

to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the
account of shareholders of the Company (or by the Company and by the shareholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in
connection with any employee stock option or other benefit plan, (ii) filed on Form F-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule

not been reached under the foregoing clauses (A) and (B), the Common Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent

2.2.3    Piggyback Registration Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder,

to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback
Registration. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in

on Form F-3 or any similar short form registration statement that may be available at such time
(“Form F-3”); provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering. Within
five (5) days of the Company’s receipt of a written request from the Initiating Holders for a Registration on Form F-3, the Company shall promptly give written notice of the proposed
Registration on Form F-3 to all other Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable
Securities in such Registration on Form F-3 shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company. As soon as practicable
thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a Registration on Form F-3, the Company shall register all or such portion of such
Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified in the written notification given by
such Holder or Holders; provided, however, that the Company shall not be obligated to effect any such Registration pursuant to Section 2.3 hereof if (i) a

(60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company
continues to actively employ, in good faith, all reasonable efforts to cause the Registration Statement for which the Holders have delivered written notice pursuant to subsection 2.1.1 to become effective; (B) the Holders have requested
an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to
the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board
stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration
Statement. In such event, the Company shall have the right to defer such filing for a period of not more than ninety (90) days; provided, however, that the Company shall not defer its obligation in this manner more than once in
any 12-month period.

thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its commercially reasonable efforts to
prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 
 3.1.8    at
least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus or any document that is to be incorporated by reference into such Registration
Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities and its counsel (excluding any exhibits thereto and any filing made under the Exchange Act that is to be incorporated by reference therein); 

3.1.9    notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be
delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in
Section 3.4 hereof; 
 3.1.10    in the event of an Underwritten Registration, permit a
representative of the Holders (such representative to be selected by a majority of the participating Holders) and any attorney or accountant retained by such Holders to participate, at each such person’s own expense, in the preparation of the
Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, attorney or accountant in connection with the Registration; provided,
however, that such representatives enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; 

3.1.11    obtain a “comfort” letter from the Company’s independent registered public accountants in the
event of an Underwritten Registration (subject to such Underwriter providing such certification or representation reasonably requested by the Company’s independent registered public accountants and the Company’s counsel) in customary form
and covering such matters of the type customarily covered by “comfort” letters for a transaction of this type as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders; 

  
 12 













 3.1.12    in the event of an Underwritten Registration, on the date the
Registrable Securities are delivered for sale pursuant to such Registration, to the extent customary for a transaction of its type, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration,
addressed to the participating Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the participating
Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters; 

3.1.13    in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing Underwriter of such offering; 
 3.1.14    make available to
its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the
Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 

3.1.15    in the event of any Underwritten Registration, if the Registration involves the Registration of Registrable
Securities involving gross proceeds in excess of $50,000,000, use its commercially reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested
by the Underwriter in any Underwritten Offering; and 
 3.1.16    otherwise, in good faith, cooperate reasonably with,
and take such customary actions as may reasonably be requested by the participating Holders, consistent with the terms of this Agreement, in connection with such Registration. 

Notwithstanding the foregoing, the Company shall not be required to provide any documents or information to an Underwriter, broker, sales agent or placement
agent if such Underwriter, broker, sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering or other offering involving a registration as an Underwriter, broker, sales agent or placement agent, as
applicable. 
 3.2    Registration Expenses. The Registration Expenses of all Registrations shall be borne by the
Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs
and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders. 

3.3    Requirements for Participation in Underwritten Offerings. Notwithstanding anything in this Agreement to the
contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities 

  
 13 













 
from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that it is necessary or advisable to include such information in the applicable
Registration Statement or Prospectus and such Holder continues thereafter to withhold such information. In addition, no person or entity may participate in any Underwritten Offering or other offering for equity securities of the Company pursuant to
a Registration initiated by the Company hereunder unless such person or entity (i) agrees to sell such person’s or entity’s securities on the basis provided in any underwriting, sales, distribution or placement arrangements approved
by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be
reasonably required under the terms of such underwriting, sales, distribution or placement arrangements. For the avoidance of doubt, the exclusion of a Holder’s Registrable Securities as a result of this Section 3.3
shall not affect the registration of the other Registrable Securities to be included in such Registration. 

3.4    Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration
Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being
understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as reasonably practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be
resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such
Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control or (c) in the good faith judgment of the majority of the Board such Registration, be seriously detrimental to the
Company and the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Holders, delay the
filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the
preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities until such
Holder receives written notice from the Company that such sales or offers of Registrable Securities may be resumed, and in each case maintain the confidentiality of such notice and its contents. The Company shall immediately notify the Holders of
the expiration of any period during which it exercised its rights under this Section 3.4. 

3.5    Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times
while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof
pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the
Commission pursuant to EDGAR shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. The Company further covenants that it shall take such further action as any Holder may reasonably
request, all to the extent required from time to time to enable such Holder 

  
 14 













 
to sell Common Shares held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or
any successor rule promulgated thereafter by the Commission). Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements. 

ARTICLE IV 

INDEMNIFICATION AND CONTRIBUTION 

4.1    Indemnification. 

4.1.1    The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its
officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and
out-of-pocket expenses (including reasonable and documented attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any
Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each
person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder. 

4.1.2    In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such
Holder shall furnish (or cause to be furnished) to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Holder
Information”) and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims,
damages, liabilities and out-of-pocket expenses (including without limitation reasonable and documented attorneys’ fees) resulting from any untrue statement of
material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein
not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to
indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from
the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the
Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company. 

4.1.3    Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party
of any claim with respect to which it seeks indemnification 

  
 15 













 
(provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying
party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of
such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent
shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties
indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to
such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by
the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to
such claim or litigation. 
 4.1.4    The indemnification provided for under this Agreement shall remain in full force
and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of
Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is
unavailable for any reason. 
 4.1.5    If the indemnification provided under Section 4.1
hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and
out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by
the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect the relative
fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether
any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party,
and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection
4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be
deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or
proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any 

  
 16 













 
other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation. 

ARTICLE V 
 MISCELLANEOUS

 5.1    Notices. Any notice or communication under this Agreement must be in writing and given by
(i) deposit in the United States mail, addressed to the party to be notified, postage prepaid and registered or certified with return receipt requested, (ii) delivery in person or by courier service providing evidence of delivery, or
(iii) transmission by hand delivery, electronic mail or facsimile. Each notice or communication that is mailed, delivered, or transmitted in the manner described above shall be deemed sufficiently given, served, sent, and received, in the case
of mailed notices, on the third business day following the date on which it is mailed and, in the case of notices delivered by courier service, hand delivery, electronic mail or facsimile, at such time as it is delivered to the addressee (with the
delivery receipt or the affidavit of messenger) or at such time as delivery is refused by the addressee upon presentation. Any notice or communication under this Agreement must be addressed, if to the Company, to: LumiraDx, Inc., 221 Crescent
Street. 5th Floor, Waltham, MA and, if to any Holder, at such Holder’s address, electronic mail address or contact information as set forth in the Company’s books and records. Any party may change its address for notice at any time
and from time to time by written notice to the other parties hereto, and such change of address shall become effective thirty (30) days after delivery of such notice as provided in this Section 5.1. 

5.2    Assignment; No Third Party Beneficiaries. 

5.2.1    This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated
by the Company in whole or in part. 
 5.2.2    Prior to the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, Sponsor shall not assign or delegate its rights, duties or obligations under this Agreement, in
whole or in part, except in connection with a transfer of Registrable Securities by Sponsor to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this Agreement. A Holder may
assign or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, to any person to whom it transfers Registrable Securities; provided that such Registrable Securities remain Registrable Securities
following such transfer and such person agrees to become bound by the terms and provisions of this Agreement. 

5.2.3    This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the
parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 

5.2.4    This Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as
expressly set forth in this Agreement and Section 5.2 hereof. 

  
 17 













 5.2.5    No assignment by any party hereto of such party’s rights,
duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section 5.1 hereof and (ii) the
written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement). Any transfer or
assignment made other than as provided in this Section 5.2 shall be null and void. 

5.3    Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF
counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced. 

5.4    Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES
HERETO, THE PARTIES EXPRESSLY AGREE THAT (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK,
WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THIS AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK. 

5.5    Amendments and Modifications. Upon the written consent of the Company and the Holders of a majority in
interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified;
provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof shall also require written consent of the Sponsor; provided, further, that notwithstanding the foregoing, any amendment hereto
or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of share capital of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so
affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any
rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by
such party. 
 5.6    Termination of Existing Registration Rights. The registration rights granted under this
Agreement shall supersede any registration, qualification or similar rights of the Holders with respect to any shares or securities of CAH or the Company granted under any other agreement, including, but not limited to, the Original Agreements, and
any of such preexisting registration, qualification or similar rights and such agreements shall be terminated and of no further force and effect. This Agreement constitutes the full and entire agreement and understanding between the parties with
respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter. Upon the Closing, the Original Agreements shall no longer be of any force or effect. 

  
 18 













 5.7    Term. This Agreement shall terminate upon the earlier of
(i) the third anniversary of the date of this Agreement, (ii) with respect to any Holder, on the date that such Holder no longer holds any Registrable Securities, or (iii) the date as of which (A) all of the Registrable
Securities have been sold pursuant to a Registration Statement (but in no event prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and Rule 174 thereunder (or any successor rule promulgated thereafter by
the Commission)) or (B) the Holders of all Registrable Securities are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold or
the manner of sale. The provisions of Section 3.5 and Article IV shall survive any termination. 

5.8    Holder Information. Each Holder agrees, if requested in writing, to represent to the Company the total
number of Registrable Securities held by such Holder in order for the Company to make determinations hereunder. 

5.9    Severability. It is the desire and intent of the parties that the provisions of this Agreement be enforced
to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to
be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or
affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall,
as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. 

5.10    Adjustments. If, and as often as, there are any changes in the Registrable Securities by way of stock
split, stock dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or sale, or by any other means, appropriate adjustment shall be made in the provisions of this Agreement, as may be required,
so that the rights, privileges, duties and obligations hereunder shall continue with respect to the Registrable Securities as so changed.
