This Agreement has been duly executed and delivered by the Sponsor and, assuming due authorization, execution and delivery by Investor, this Agreement constitutes a legally valid and binding obligation of the Sponsor, enforceable against the Sponsor in accordance with the terms hereof (except as enforceability may be limited by bankruptcy Laws, other similar Laws affecting creditors’ rights and general principles of equity affecting the availability of specific performance and other equitable remedies).

(b) The Sponsor is the record owner, and has good and marketable title to, all of the Transferred Sponsor Shares.

Investor shall be a Permitted Transferee pursuant to the Registration Rights Agreement with respect to the Transferred Sponsor Shares.

(c) The execution and delivery of this Agreement by the Sponsor does not, and the performance by the Sponsor of its obligations hereunder will not, (i) conflict with or result in a violation of the organizational documents of the Sponsor or (ii) require any consent or approval that has not been given or other action that has not been taken by any person, in each case to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by the Sponsor of its obligations under this Agreement. The Sponsor has full right and power to enter into this Agreement.

(d) The Sponsor is not engaged in a distribution, as such term is used in Regulation M under the Exchange Act, of any securities of CAH. The Sponsor shall not engage in any such distribution until after the Closing.

(b) The execution and delivery of this Agreement by Investor does not, and the performance by Investor of its obligations hereunder will not, (i) conflict with or result in a violation of the organizational documents of Investor or (ii) require any consent or approval that has not been given or other action that has not been taken by any person, in each case to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by Investor of its obligations under this Agreement. Investor has full right and power to enter into this Agreement.

(c) Each of the managed accounts and fund entities over which Investor has investment discretion is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities Act, and neither Investor nor any of the managed accounts or fund entities referred to above have experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act.

(d) Investor understands that any Transferred Sponsor Shares that may be transferred to Investor (or managed accounts or fund entities) pursuant to this Agreement are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Transferred Sponsor Shares have not been registered under the Securities Act.

Investor acknowledges and agrees that the Transferred Sponsor Shares will be subject to these securities law transfer restrictions and, as a result of these transfer restrictions, Investor may not be able to readily resell the Transferred Sponsor Shares and may be required to bear the financial risk of an investment in the Transferred Sponsor Shares for an indefinite period of time. Investor understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the Transferred Sponsor Shares.

(e) In making its decision to invest in the Transferred Sponsor Shares, Investor has relied solely upon independent investigation made by Investor and the Sponsor’s representations, warranties and covenants contained herein. Investor has not relied on any statements or other information provided by anyone other than the Sponsor concerning LumiraDx, CAH, the Merger, the Transferred Sponsor Shares or the offer of the Transferred Sponsor Shares. Investor acknowledges and agrees that Investor has received and has had an adequate opportunity to review such financial and other information as Investor deems necessary in order to make an investment decision with respect to the Transferred Sponsor Shares, including with respect to LumiraDx, CAH and the Merger, and made its own assessment and is satisfied concerning the relevant tax and other economic considerations relevant to Investor’s investment in the Transferred Sponsor Shares. Investor represents and agrees that Investor and Investor’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as Investor and such undersigned’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Transferred Sponsor Shares. Without limiting the generality of the foregoing, Investor acknowledges that it has reviewed CAH’s filings with the SEC.

(f) Investor became aware of the offering of the Transferred Sponsor Shares solely by means of direct contact between Investor and the Sponsor or its representatives or affiliates. Investor did not become aware of the offering of the Transferred Sponsor Shares, nor were the Transferred Sponsor Shares offered to Investor, by any other means.

(g) Investor acknowledges that it is aware that there are substantial risks incident to the ownership of the Transferred Sponsor Shares. Investor 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 Transferred Sponsor Shares, and Investor has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Investor has considered necessary to make an informed investment decision. Investor is not relying on any statements or representations of the Sponsor or any of its agents for legal, tax or investment advice with respect to this Agreement or the transactions contemplated by the Agreement.

(h) Investor has adequately analyzed and fully considered the risks of an investment in the Transferred Sponsor Shares and determined that the Transferred Sponsor Shares are a suitable investment for Investor and that Investor is able at this time and in the foreseeable future to bear the economic risk of a total loss of Investor’s investment in the Transferred Sponsor Shares. Investor acknowledges specifically that a possibility of total loss exists.

(i) Investor understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Transferred Sponsor Shares or made any findings or determination as to the fairness of this investment.

(j) No broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with this Agreement.

(k) Investor is not entering into the transactions contemplated by this Agreement to create actual or apparent trading activity in the CAH Class A Common Stock (or any security convertible into or exchangeable for CAH Class A Common Stock) or to raise or depress or otherwise manipulate the price of the CAH Class A Common Stock (or any security convertible into or exchangeable for the CAH Class A Common Stock) or otherwise in violation of the Exchange Act. Investor has not entered into or altered, and agrees that Investor will not enter into or alter, any corresponding or hedging transaction or position with respect to the CAH Class A Common Stock.

ARTICLE IV
MISCELLANEOUS

4.1 Termination. This Agreement and all of its provisions shall terminate and be of no further force or effect only automatically upon (a) the termination of the Merger Agreement in accordance with its terms, (b) if the Closing has not occurred by September 30, 2021, written notice from Investor electing to terminate the Agreement, (c) if a Material Adverse Change (as defined below) has occurred, written notice from Investor electing to terminate this Agreement, or (d) upon the written agreement of the Sponsor and Investor. Upon such termination of this Agreement, all obligations of the parties under this Agreement will terminate, without any liability or other obligation on the part of any party hereto to any person in respect hereof or the transactions contemplated hereby. This Article IV shall survive the termination of this Agreement.

4.2 Trust Account Waiver. Investor acknowledges that CAH is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving CAH and one or more businesses or assets. Investor further acknowledges that, as described in CAH’s prospectus relating to its initial public offering dated January 29, 2021 (the “Prospectus”) available at www.sec.gov, substantially all of CAH’s assets consist of the cash proceeds of CAH’s initial public offering and private placements of its securities, and substantially all of those proceeds have been deposited in the Trust Account for the benefit of CAH, its public stockholders and the underwriters of CAH’s initial public offering. For and in consideration of the Sponsor entering into this Agreement, the receipt and sufficiency of which are hereby acknowledged, Investor hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account for any reason whatsoever.

4.3 Public Disclosure. Notwithstanding anything in this Agreement to the contrary, Investor agrees that CAH shall have the right to publicly disclose the name of Investor, its investment adviser or any of their respective affiliates, Investor’s beneficial ownership of the Transferred Sponsor Shares and CAH Class A Common Stock, or the nature of Investor’s commitments, arrangements and understandings under and relating to this Agreement in any press release issued by CAH, any Form 8-K filed by CAH with the SEC in connection with the execution and delivery of this Agreement and any registration statement filed or amended on or after the date of this Agreement. Investor shall promptly provide any information reasonably requested by CAH for any regulatory application or filing made or approval sought in connection with the Merger (including filings with the SEC). Prior to making any such public disclosure, the Sponsor shall use commercially reasonable efforts to (a) provide Investor with three (3) Business Days to review the portion of any public filing, press release or other public disclosure that refers directly to Investor’s commitment pursuant to this Agreement and (b) incorporate any reasonable comments received from Investor or its representatives within such three (3) Business Day period as to such public disclosures referring directly to Investor’s commitment pursuant to this Agreement (it being understood, however, that with respect to the initial public disclosure as to the existence of this Agreement, such three (3) Business Day period may be reduced by the Sponsor to a one (1) Business Day period).

4.4 Governing Law. This Agreement, the rights and duties of the parties hereto, and any disputes (whether in contract, tort or statute) arising out of, under or in connection with this Agreement will be governed by and construed and enforced in accordance with the Laws of the State of Delaware, without giving effect to its principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of the laws of another jurisdiction. The parties irrevocably and unconditionally submit to the exclusive jurisdiction of the United States District Court for the District of Delaware or, if such court does not have jurisdiction, the Delaware state courts located in Wilmington, Delaware, in any action arising out of or relating to this Agreement. The parties irrevocably agree that all such claims shall be heard and determined in such a Delaware federal or state court, and that such jurisdiction of such courts with respect thereto will be exclusive. Each party hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding arising out of or relating to this Agreement that it is not subject to such jurisdiction, or that such action, suit or proceeding may not be brought or is not maintainable in such courts or that the venue thereof may not be appropriate or that this Agreement may not be enforced in or by such courts. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of any such dispute and agree that mailing of process or other papers in connection with any such action, suit or proceeding in the manner provided in Section 4.11 or in such other manner as may be permitted by law, will be valid and sufficient service thereof.

4.5 Waiver of Jury Trial. To the extent not prohibited by applicable law that cannot be waived, each of the parties hereto irrevocably waives any right it may have to trial by jury in respect of any litigation based on, arising out of, under or in connection with this Agreement or any course of conduct, course of dealing, verbal or written statement or action of any party hereto or thereto, in each case, whether now existing or hereafter arising, and whether in contract, tort, statute, equity or otherwise.

4.8 Specific Performance. The parties agree that irreparable damage may occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.
