WHEREAS, this Subscription Agreement is being entered into in connection with the Agreement and Plan of Merger, dated as of the date hereof
(as may be amended, supplemented or otherwise modified from time to time, the “Transaction Agreement”), by and among KVSA, Valo Health, LLC, a Delaware limited liability company (“Valo Holdco”), Valo Health, Inc., a
Delaware corporation (the “Company”), Killington Merger Sub Inc., a Delaware corporation (“KVSA Merger Sub”), and the other parties thereto, in substantially the form provided to the Investor prior to the date hereof, pursuant to
which, among other things, KVSA Merger Sub will merge with and into the Company, with the Company as the surviving company in the merger and, after giving effect to such merger, becoming a wholly owned subsidiary of KVSA, and KVSA will change its
name to “Valo Health, Inc.”, on the terms and subject to the conditions therein (the “Transaction”); 
 WHEREAS, in
connection with the Transaction, KVSA is seeking commitments from interested investors to purchase, prior to the closing of the Transaction, shares of KVSA’s Class A common stock, par value $0.001 per share, as such shares will exist as

WHEREAS, the aggregate purchase price to be paid by the Investor for the subscribed Shares (as set forth on the signature page hereto) is
referred to herein as the “Subscription Amount;” and 
 WHEREAS, substantially concurrently with the execution of this
Subscription Agreement, KVSA is entering into separate subscription agreements with certain other investors (the “Other Subscription Agreements”) with an aggregate purchase price of
$[                 ] (inclusive of the Subscription Amount) (the “PIPE Investment”). 

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set
forth herein, and intending to be legally bound hereby, each of the Investor and KVSA acknowledges and agrees as follows: 
 1.

contain an appropriate notation or legend concerning transfer restrictions of the Shares, in accordance with any applicable securities laws of the states of the United States and other applicable jurisdictions. For purposes of this Subscription

funds to the account specified by the Investor, and any book-entries for the Shares shall be deemed cancelled; provided that, unless this Subscription Agreement has been terminated pursuant to Section 8 hereof, such
return of funds shall not terminate this Subscription Agreement or relieve the Investor of its obligation to purchase the Shares at the Closing.

assets of KVSA or any of its subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which KVSA or any of its subsidiaries is a party or by which KVSA or
any of its subsidiaries is bound or to which any of the property or assets of KVSA is subject that would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, financial condition or results of

this Subscription Agreement; (ii) result in any violation of the provisions of the organizational documents of KVSA; or (iii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental
agency or body, domestic or foreign, having jurisdiction over KVSA or any of its properties that would reasonably be expected to have a Material Adverse Effect or materially affect the validity of the Shares or the legal authority of KVSA to comply
in all material respects with its obligations under this Subscription Agreement. 
 (e) As of their respective filing dates, all reports
required to be filed by KVSA with the U.S. Securities and Exchange Commission (the “SEC”) since March 1, 2021 (the “SEC Reports”) complied in all material respects with the applicable requirements of the

(g) KVSA is in compliance with all applicable law, and KVSA has not received any written communication from a governmental authority that
alleges that KVSA is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not reasonably be expected to have, individually or
in the aggregate, a Material Adverse Effect.

sale of the Shares other than to the Placement Agents. KVSA or the Company is responsible for the payment of any fees or commissions of the Placement Agents. 

(l) The Other Subscription Agreements reflect the same Per Share Subscription Price and other terms with respect to the purchase of the Shares
that are no more favorable to such subscriber thereunder than the terms of this Subscription Agreement, other than terms particular to the regulatory requirements of such subscriber or its affiliates or related funds. KVSA has not entered into any
side letter or similar arrangement with any other subscriber under the Other Subscription Agreements in connection with the PIPE Investment. 

(m) None of KVSA, any of its officers, directors, managers, managing members, general partners or any other person acting in a similar
capacity or carrying out a similar function, is (i) named on the Specially Designated Nationals and Blocked Persons List, the Foreign Sanctions Evaders List, the Sectoral Sanctions Identification List, or any other similar list of sanctioned

Assets Control Regulations, 31 C.F.R. Part 515; or (v) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (collectively,

Act”), and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that KVSA maintains or will maintain policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT
Act. KVSA also represents and covenants that it maintains and will maintain policies and procedures reasonably designed to ensure compliance with sanctions administered by the United States, the European Union, or any individual European Union
member state, including the United Kingdom, to the extent applicable to it. KVSA further covenants that it will not directly or indirectly use the proceeds of the PIPE Investment hereunder; lend, contribute or otherwise make available such proceeds

 (a) The Investor (i) is (A) a “qualified institutional buyer” (as
defined in Rule 144A under the Securities Act), (B) an “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3), (5), (7) or (8) under the Securities Act), in each case, satisfying the applicable requirements
set forth on Schedule A or (C) an Institutional Account as defined in FINRA Rule 4512(c), (ii) is acquiring the Shares only for his, her or its own account and not for the account of others, or if the Investor is

agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the
requested information set forth on Schedule A). The Investor is not an entity formed for the specific purpose of acquiring the Shares. 

(b) The Investor acknowledges and agrees that the Shares are being offered in a transaction not involving any public offering within the
meaning of the Securities Act, that the Shares have not been registered under the Securities Act and that KVSA is not required to register the Shares except as set forth in Section 7 of this Subscription Agreement. The
Investor acknowledges and agrees that the Shares may not be offered, resold, transferred, pledged or otherwise disposed of by the Investor absent an effective registration statement under the Securities Act except (i) to KVSA or a subsidiary
thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable
exemption from the registration requirements of the Securities Act, and, in each case, in accordance with any applicable securities laws of the states of the United States and other applicable jurisdictions, and that any certificates or book entry
records representing the Shares shall contain a restrictive legend to such effect. The Investor acknowledges and agrees that the Shares will be subject to these securities law transfer restrictions and, as a result of these transfer restrictions,
the Investor may not be able to readily offer, resell, transfer, pledge or otherwise dispose of the Shares and may be required to bear the financial risk of an investment in the Shares for an indefinite period of time. The Investor acknowledges and
agrees that the Shares will not immediately be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act, and that the provisions of Rule 144(i) will apply to the Shares. The Investor
acknowledges and agrees that it has been advised to consult legal, tax and accounting prior to making any offer, resale, transfer, pledge or disposition of any of the Shares. 

(c) The Investor acknowledges and agrees that the Investor is purchasing the Shares from KVSA. The Investor further acknowledges that there
have been no representations, warranties, covenants and agreements made to the Investor by or on behalf of KVSA, the Company, any of their respective affiliates or any control persons, officers, directors, employees, agents or representatives of any
of the foregoing or any other person or entity, expressly or by implication, other than the SEC Reports and those representations, warranties, covenants and agreements of KVSA expressly set forth in this Subscription Agreement. 

(d) The Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make an
investment decision with respect to the Shares, including, with respect to KVSA, the Transaction and the business of the Company and its subsidiaries. Without limiting the generality of the foregoing, the Investor acknowledges that he, she or it has
had the opportunity to review the SEC Reports. The Investor acknowledges and agrees that the Investor and the Investor’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such
information as the Investor and such Investor’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares. 

(e) The Investor became aware of this offering of the Shares solely by means of direct contact between the Investor and KVSA, the Company or a
representative of KVSA or the Company, and the Shares were offered to the Investor solely by direct contact between the Investor and KVSA, the Company or a representative of KVSA or the Company. The Investor did not become aware of this offering of
the Shares, nor were the Shares offered to the Investor, by any other means. The Investor acknowledges 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. The Investor acknowledges that it is not relying upon, and has not relied upon, any statement, representation or
warranty made by any person, firm or corporation (including, without limitation, KVSA, the Company, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees, agents or representatives of any of
the foregoing), other than the SEC Reports and the representations and warranties of KVSA contained in this Subscription Agreement, in making its investment or decision to invest in KVSA. 

  
 5 













 (f) The Investor acknowledges that it is aware that there are substantial risks incident to
the purchase and ownership of the Shares, including those set forth in KVSA’s filings with the SEC. The 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 Shares, and the Investor has sought such accounting, legal and tax advice as the Investor has considered necessary to make an informed investment decision. The Investor acknowledges that Investor shall be responsible for any of the
Investor’s tax liabilities that may arise as a result of the transactions contemplated by this Subscription Agreement, and that neither KVSA nor the Company has provided any tax advice or any other representation or guarantee regarding the tax
consequences of the transactions contemplated by the Subscription Agreement. 
 (g) Alone, or together with any professional advisor(s), the
Investor has adequately analyzed and fully considered the risks of an investment in the Shares and that the Investor is able at this time and in the foreseeable future to bear the economic risk of a total loss of the Investor’s investment in
KVSA. The Investor acknowledges specifically that a possibility of total loss exists. 
 (h) In making its decision to purchase the Shares,
the Investor has relied solely upon independent investigation made by the Investor, the SEC Reports and the representations and warranties made by KVSA in this Subscription Agreement. Without limiting the generality of the foregoing, the Investor
has not relied on any statements or other information provided by or on behalf of the Placement Agents or any of their respective affiliates or any control persons, officers, directors, employees, agents or representatives of any of the foregoing
concerning KVSA, the Company, the Transaction, the Transaction Agreement, this Subscription Agreement or the transactions contemplated hereby or thereby, the Shares or the offer and sale of the Shares.

findings or determination as to the fairness of this investment. 
 (j) The Investor, if not a natural person, has been duly formed or
incorporated and is validly existing and is in good standing under the laws of its jurisdiction of formation or incorporation (to the extent such concept exists in such jurisdiction), with power and authority to enter into, deliver and perform its
obligations under this Subscription Agreement. 
 (k) The execution, delivery and performance by the Investor of this Subscription Agreement
are within the powers of the Investor, have been duly authorized and will not constitute or result in a breach or default under or conflict with any order, ruling or regulation of any court or other tribunal or of any governmental commission or
agency, or any agreement or other undertaking, to which the Investor is a party or by which the Investor is bound, that would reasonably be expected to have a material adverse effect on the ability of the Investor to consummate the transactions
contemplated hereby, and, if the Investor is not a natural person, will not violate any provisions of the Investor’s organizational documents, including, without limitation, its incorporation or formation papers, bylaws, indenture of trust or
partnership or operating agreement, as may be applicable. The signature of the Investor on this Subscription Agreement is genuine, and the signatory, if the Investor is a natural person, has legal competence and capacity to execute the same or, if
the Investor is not a natural person, the signatory has been duly authorized to execute the same, and, assuming that this Subscription Agreement constitutes the valid and binding agreement of KVSA, this Subscription Agreement constitutes a legal,
valid and binding obligation of the Investor, enforceable against the Investor in accordance with its terms except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other
laws relating to or affecting the rights of creditors generally, and (ii) principles of equity, whether considered at law or equity. 

(l) Neither the Investor nor, if the Investor is not a natural person, any of its officers, directors, managers, managing members, general
partners or any other person acting in a similar capacity or carrying out a similar function, is (i) a person named on the Sanctions List; (ii) directly or indirectly owned or controlled by, or acting on behalf of, one or more persons on a
Sanctions List; (iii) organized, incorporated, established, located, resident or born in, or a citizen, national, or the government, including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria,

National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515; or (v) a non-U.S. shell bank or providing banking services indirectly to a non-U.S.
shell bank (collectively, a “Prohibited Investor”). The Investor further represents that the funds held by the Investor and used to purchase the Shares were legally derived and were not obtained, directly or indirectly, from a
Prohibited Investor.

of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) a plan, an individual retirement account or other arrangement that is subject to Section 4975 of the Internal Revenue Code of 1986, as
amended (the “Code”), (iii) an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement described in clauses (i) and (ii) (each, an “ERISA
Plan”), or (iv) an employee benefit plan that is a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA), a non-U.S. plan (as

non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws,” and together with ERISA Plans, “Plans”), the
Investor represents and warrants that (A) neither KVSA nor any of its affiliates (the “Transaction Parties”) has provided investment advice or has otherwise acted as the Plan’s fiduciary, with respect to its decision to
acquire and hold the Shares, and none of the parties to the Transaction is or shall at any time be the Plan’s fiduciary with respect to any decision in connection with the Investor’s investment in the Shares; and (B) its purchase of
the Shares will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, or any applicable Similar Law.

the Investor’s underwriter, initial purchaser, dealer, financial advisor, fiduciary or in any other such capacity. 
 (q) The Investor
has or has commitments to have and, when required to deliver payment to KVSA pursuant to Section 2 above, will have, sufficient funds to pay the Subscription Amount and consummate the purchase and sale of the Shares
pursuant to this Subscription Agreement.

 7.
Registration Rights. 
 (a) KVSA agrees that, within thirty (30) calendar days following the Closing Date (such deadline, the
“Filing Deadline”), KVSA will submit to or file with the SEC a registration statement for a shelf registration on Form S-1 or Form S-3 (if the Company
is then eligible to use a Form S-3 shelf registration) (the “Registration Statement”), in each case, covering the resale of the Shares acquired by the Investor pursuant to this Subscription
Agreement which are eligible for registration (determined as of two (2) business days prior to such submission or filing) (the “Registrable Shares”) and KVSA 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) the 90th calendar day following the Closing Date if the SEC notifies KVSA that it will “review” the
Registration Statement and (ii) the fifth business day after the date KVSA is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further
review (such earlier date, the “Effectiveness Deadline”); provided, however, that (x) KVSA shall use its commercially reasonable efforts to provide a draft of the initial Registration Statement to the
Investor for review at least two (2) business days in 

  
 7 













 
advance of the filing of the initial Registration Statement, so long as KVSA shall not be required to delay or postpone the filing of such initial Registration Statement as a result of or in
connection with the Investor’s review; and (y) KVSA’s obligations to include the Registrable Shares in the Registration Statement are contingent upon Investor furnishing in writing to KVSA such information regarding Investor, the
securities of KVSA held by Investor and the intended method of disposition of the Registrable Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by KVSA to
effect the registration of the Registrable Shares, and Investor shall execute such documents in connection with such registration as KVSA may reasonably request that are customary of a selling stockholder in similar situations; provided that
Investor shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable
Shares. The Registration Statement shall include a “plan of distribution” that permits all lawful means of disposition of the Registrable Shares by the Investor, including block sales, agented transactions, sales directly into the market
and other customary provisions (but, excluding for the avoidance of doubt, underwritten offerings). For as long as the Investor holds Shares, KVSA will use commercially reasonable efforts to file all reports for so long as the condition in Rule
144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Shares pursuant to Rule 144 of the Securities Act (in each case, when
Rule 144 of the Securities Act becomes available to the Investors), including providing any legal opinions to KVSA’s transfer agent. Any failure by KVSA to file the Registration Statement by the Filing Deadline or to effect such Registration
Statement by the Effectiveness Deadline shall not otherwise relieve KVSA of its obligations to file or effect the Registration Statement as set forth above in this Section 7. 

(b) At its expense KVSA shall: 

(i) except for such times as KVSA is permitted hereunder to suspend the use of the prospectus forming part of a Registration
Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which KVSA determines to obtain, continuously effective with respect to Investor, and to keep
the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (A) Investor ceases to hold any Registrable Shares, (B) the date all
Registrable Shares held by Investor may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for KVSA to
be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (C) two years from the date of effectiveness of the Registration Statement. The period of time during which KVSA is
required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”; 

(ii) during the Registration Period, advise Investor, as expeditiously as possible: 

(1) when a Registration Statement or any amendment thereto has been filed with the SEC; 

(2) after it shall receive notice or obtain knowledge thereof, of the issuance by the SEC of any stop order suspending the
effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; 
 (3) of the receipt by
KVSA of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(4) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any
changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case
of a prospectus, in the light of the circumstances under which they were made) not misleading. 

  
 8 













 Notwithstanding anything to the contrary set forth herein, KVSA shall not, when so advising Investor of such
events, provide Investor with any material, nonpublic information regarding KVSA other than to the extent that providing notice to Investor of the occurrence of the events listed in (1) through (4) above constitutes material, nonpublic
information regarding KVSA; 
 (iii) during the Registration Period, use its commercially reasonable efforts to obtain the
withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable; 
 (iv)
during the Registration Period, upon the occurrence of any event contemplated in Section 7(b)(ii)(4) above, except for such times as KVSA is permitted hereunder to suspend, and has suspended, the use of a prospectus
forming part of a Registration Statement, KVSA shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file
any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading; 
 (v) during the
Registration Period, use its commercially reasonable efforts to cause all Registrable Shares to be listed on each securities exchange or market, if any, on which the Class A Shares issued by KVSA have been listed; 

(vi) during the Registration Period, use its commercially reasonable efforts to allow the Investor to review disclosure
regarding the Investor in the Registration Statement; and 
 (vii) otherwise, in good faith, during the Registration Period,
cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investor, consistent with the terms of this Subscription Agreement, in connection with the registration of the Registrable Shares. 

(c) Notwithstanding anything to the contrary in this Subscription Agreement, KVSA shall be entitled to delay the filing or effectiveness of,
or suspend the use of, the Registration Statement if it determines that in order for the Registration Statement not to contain a material misstatement or omission, (i) an amendment thereto would be needed to include information that would at
that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (ii) the negotiation or consummation of a transaction by KVSA or its subsidiaries is pending or an event has occurred, which negotiation,
consummation or event KVSA’s board of directors reasonably believes would require additional disclosure by KVSA in the Registration Statement of material information that KVSA has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of KVSA’s board of directors to cause the Registration Statement to fail to comply with applicable
disclosure requirements, or (iii) in the good faith judgment of the majority of KVSA’s board of directors, such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to the Company and the majority
of the KVSA board or directors concludes as a result that it is essential to defer such filing (each such circumstance, a “Suspension Event”); provided, however, that KVSA may not delay or suspend the Registration
Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90)total calendar days in each case during any twelve-month period. Upon receipt of any written notice from KVSA of the happening
of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any
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 prospectus) not misleading, Investor agrees that (i) it will immediately
discontinue offers and sales of the Registrable Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Investor receives copies of a supplemental or amended prospectus (which KVSA
agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by KVSA that it may resume such offers and sales,
and (ii) it will maintain the confidentiality of any information included in such written notice delivered by KVSA unless otherwise required by 

  
 9 













 
law or subpoena. If so directed by KVSA, Investor will deliver to KVSA or, in Investor’s sole discretion destroy, all copies of the prospectus covering the Registrable Shares in
Investor’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Shares shall not apply (A) to the extent Investor is required to retain a copy of such
prospectus (1) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (2) in accordance with a bona fide pre-existing document retention policy or
(B) to copies stored electronically on archival servers as a result of automatic data back-up. 

(d) Indemnification. 

(i) KVSA agrees to indemnify, to the extent permitted by law, Investor (to the extent a seller under the Registration
Statement), its directors and officers and each person who controls Investor (within the meaning of the Securities Act), to the extent permitted by law, against all losses, claims, damages, liabilities and reasonable and documented out of pocket
expenses (including reasonable and documented attorneys’ fees of one law firm) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included 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 (in the case of
a Prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are solely caused by or contained in any information or affidavit so furnished in writing to KVSA by or on behalf of such Investor
expressly for use therein. 
 (ii) In connection with any Registration Statement in which an Investor is participating, such
Investor shall furnish (or cause to be furnished) to KVSA in writing such information and affidavits as KVSA reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall
indemnify KVSA, its directors and officers and each person or entity who controls KVSA (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable outside
attorneys’ fees) resulting solely from any untrue or alleged untrue statement of material fact contained or incorporated by reference 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 (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, but
only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission) in any information or affidavit so furnished in writing by on behalf of such Investor expressly for use therein;
provided, however, that the liability of each such Investor shall be several and not joint and shall be in proportion to and limited to the net proceeds received by such Investor from the sale of Registrable Shares giving rise to such
indemnification obligation. 
 (iii) Any person or entity entitled to indemnification herein shall (A) give prompt
written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to
the extent such failure has not prejudiced the indemnifying party) and (B) 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 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


  
 10 













 
money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of
such indemnified party or which 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.

(iv) The indemnification provided for under this Subscription 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 or entity of such indemnified party and shall survive the transfer of securities.

(v) If the indemnification provided under this Section 7(d) from the indemnifying party is
unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and 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 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; provided, however, the liability of the Investor shall be limited to the net proceeds received by such Investor from the sale of Registrable Shares giving rise to such indemnification
obligation. 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 not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), 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. 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 Sections 7(d)(i), (ii) and (iii) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any
investigation or proceeding. 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 Section 7(d)(v) from any
person or entity who was not guilty of such fraudulent misrepresentation. 
 8. 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 earliest to occur of (i) such
date and time as the Transaction Agreement is terminated in accordance with its terms, (ii) upon the mutual written agreement of each of the parties hereto (and the Company) to terminate this Subscription Agreement, (iii) if the conditions
to Closing set forth in Section 3 of this Subscription Agreement are not satisfied, or are not capable of being satisfied, on or prior to the Closing and, as a result thereof, the transactions contemplated by this
Subscription Agreement will not be or are not consummated at the Closing and (iv) at the election of Investor, on or after the date that is 180 days after the date hereof if the Closing has not occurred on or prior to such date; provided
that 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 any
such willful breach. KVSA shall notify the Investor of the termination of the Transaction Agreement promptly after the termination of such agreement. Upon the termination of this Subscription Agreement in accordance with this
Section 8, any monies paid by the Investor to KVSA in connection herewith shall be promptly (and in any event within one business day after such termination) returned to the Investor. 

9. Investor Covenant. Investor hereby agrees that, from the date of this Subscription Agreement, none of Investor, its controlled
affiliates, or any person or entity acting on behalf of Investor or any of its controlled affiliates or pursuant to any understanding with Investor or any of its controlled affiliates will engage in any Short Sales with respect to securities of the
KVSA prior to the Closing. For purposes of this Section 9, “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange
Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including


  
 11 













 
on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing,
(i) nothing herein shall prohibit other entities under common management with Investor that have no knowledge of this Subscription Agreement or of Investor’s participation in the Transaction or PIPE Investment (including Investor’s
controlled affiliates and/or affiliates) from entering into any Short Sales and (ii) in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s
assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the covenant set forth above shall only apply with respect to the portion of
assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Subscription Agreement. 

10. Trust Account Waiver. The Investor acknowledges that KVSA is a blank check company with the powers and privileges to effect a
merger, asset acquisition, reorganization or similar business combination involving KVSA and one or more businesses or assets. The Investor further acknowledges that, as described in KVSA’s prospectus relating to its initial public offering
dated March 3, 2021 (the “Prospectus”) available at www.sec.gov, substantially all of KVSA’s assets consist of the cash proceeds of KVSA’s initial public offering and private placement of its securities, and
substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of KVSA, its public stockholders and the underwriter of KVSA’s initial public offering. Except with respect to
interest earned on the funds held in the Trust Account that may be released to KVSA to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus. For and in consideration of
KVSA entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the 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, regardless of whether such claim arises as a result of, in connection with or relating in any way to, this Subscription Agreement or any proposed or actual business relationship between KVSA or its
affiliates, on the one hand, and the Investor 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 and irrevocably agrees
not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement. Investor agrees and acknowledges that such irrevocable waiver is material to this Subscription Agreement and specifically relied upon by
KVSA and its affiliates to induce KVSA to enter in this Subscription Agreement, and each such party further intends and understands such waiver to be valid, binding and enforceable against the Investor and its affiliates under applicable law. To the
extent Investor commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to KVSA or its affiliates, which proceeding seeks, in whole or in part, monetary relief against KVSA or its
affiliates, the Investor hereby acknowledges and agrees that the Investor’s sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit the Investor (or any person claiming on any of their behalves
or in lieu of any of the Investor) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein and in the event of any action or proceeding based upon, in connection with, relating to or
arising out of any matter relating to KVSA or its affiliates, which proceeding seeks, in whole or in part, relief against the Trust Account (including any distributions therefrom) in violation of this Subscription Agreement, KVSA shall be entitled
to recover from the Investor and its affiliates, the associated legal fees and costs in connection with any such action, in the event KVSA or its affiliates, as applicable, prevails in such action or proceeding. Notwithstanding anything else in this
Section 10 to the contrary, nothing herein shall be deemed to limit the Investor or it’s affiliates’ right, title, interest or claim to the Trust Account by virtue of the Investor’s record or beneficial
ownership of Shares of KVSA acquired by any means other than pursuant to this Subscription Agreement, including but not limited to any redemption right with respect to any such securities of KVSA. 

11. Miscellaneous. 
 (a)
Neither this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than the Shares acquired hereunder, if any) may be transferred or assigned, other than an assignment to any fund or account managed by the same
investment manager as the Investor or an affiliate thereof, subject to, if such transfer or assignment is prior to the Closing, such transferee or assignee, as applicable, executing a joinder to this Subscription Agreement or a separate subscription
agreement in substantially the same form as this Subscription Agreement, including with respect to the Subscription Amount and other terms and conditions, provided, that, in the case of any such transfer or assignment, the initial party to
this Subscription Agreement shall remain bound by its obligations under this Subscription Agreement in the event that the transferee or assignee, as applicable, does not comply with its obligations to consummate the purchase of Shares contemplated
hereby. Neither this Subscription Agreement nor any rights that may accrue to KVSA hereunder or any of KVSA’s obligations may be transferred or assigned other than pursuant to the Transactions. 

  
 12 













 (b) KVSA may request from the Investor such additional information as KVSA may deem
necessary to evaluate the eligibility of the Investor to acquire the Shares and in connection with the inclusion of the Shares in the Registration Statement, and the Investor shall provide such information as may reasonably be requested, to the
extent readily available and to the extent consistent with its internal policies and procedures. The Investor acknowledges that KVSA may file a copy of this Subscription Agreement with the SEC as an exhibit to a current or periodic report or a
registration statement of KVSA. 
 (c) The Investor acknowledges that KVSA, the Placement Agents (as third-party beneficiaries with rights
of enforcement) and others will rely on the acknowledgments, understandings, agreements, representations and warranties of the Investor contained in this Subscription Agreement. Prior to the Closing, the Investor agrees to promptly notify KVSA, the
Company and the Placement Agents if any of the acknowledgments, understandings, agreements, representations and warranties of the Investor set forth herein are no longer accurate. The Investor acknowledges and agrees that each purchase by the
Investor of Shares from KVSA will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein (as modified by any such notification) by the Investor as of the time of such purchase. 

(d) KVSA, the Placement Agents and the Investor are each entitled to rely upon this Subscription Agreement and each 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. 

(e) All of the representations and warranties contained in this Subscription Agreement shall survive the Closing. All of the covenants and
agreements made by each party hereto in this Subscription Agreement shall survive the Closing. 
 (f) This Subscription Agreement may not be
modified, waived or terminated (other than pursuant to the terms of Section 8 above) except by an instrument in writing, signed by each of the parties hereto and, to the extent required by the Transaction Agreement, the
Company. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce
such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties and third party beneficiaries hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have hereunder. 
 (g) This Subscription Agreement (including the schedule
hereto) 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. Except as set forth in
Section 11(c) with respect to the persons referenced therein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and
assigns. 
 (h) Except as otherwise provided herein, 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. 
 (i) If any provision of
this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to 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. The parties hereto shall endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which
comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). 

  
 13 













 (j) This Subscription Agreement may be executed in one or more counterparts (including by
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. Counterparts may be delivered via facsimile, electronic mail (including any electronic
signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered
shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement. 

(k) The parties hereto acknowledge and 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 an injunction or injunctions to prevent breaches of this Subscription Agreement, without
posting a bond or undertaking and without proof of damages, 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. The parties hereto acknowledge and agree that the Company and the Placement Agents shall be entitled to specifically enforce the Investor’s obligations to fund the Subscription Amount and the provisions of the Subscription
Agreement of which the Placement Agents are express third party beneficiaries, on the terms and subject to the conditions set forth herein. 

(l) This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this Subscription
Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of this Subscription Agreement, shall be governed by and construed in accordance with the laws of the
State of Delaware, without giving effect to the principles of conflicts of law thereof. 
 (m) THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE
EXCLUSIVE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, TO THE EXTENT SUCH COURT DOES NOT HAVE SUBJECT MATTER JURISDICTION, THE SUPERIOR COURT OF THE STATE OF DELAWARE, OR THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF
DELAWARE) IN RESPECT OF THE INTERPRETATION AND ENFORCEMENT OF THE PROVISIONS OF THIS SUBSCRIPTION AGREEMENT AND THE DOCUMENTS REFERRED TO IN THIS SUBSCRIPTION AGREEMENT AND IN RESPECT OF THE TRANSACTIONS CONTEMPLATED HEREBY, AND HEREBY WAIVE, AND
AGREE NOT TO ASSERT, AS A DEFENSE IN ANY ACTION, SUIT OR PROCEEDING FOR INTERPRETATION OR ENFORCEMENT HEREOF OR ANY SUCH DOCUMENT THAT IS NOT SUBJECT THERETO OR THAT SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID
COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE OR THAT THIS SUBSCRIPTION AGREEMENT OR ANY SUCH DOCUMENT MAY NOT BE ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES HERETO IRREVOCABLY AGREE THAT ALL CLAIMS WITH RESPECT TO SUCH ACTION, SUIT OR
PROCEEDING SHALL BE HEARD AND DETERMINED BY SUCH A DELAWARE STATE OR FEDERAL COURT. THE PARTIES HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT
MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER PROVIDED IN THIS SECTION 11(l) OF THIS SUBSCRIPTION AGREEMENT OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT
SERVICE THEREOF. 
 (n) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS SUBSCRIPTION AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS SUBSCRIPTION AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER
PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE 

  
 14 













 
FOREGOING WAIVER; (II) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY AND (IV) SUCH
PARTY HAS BEEN INDUCED TO ENTER INTO THIS SUBSCRIPTION AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 11(m). 

12. Non-Reliance and Exculpation. The Investor acknowledges that it is not relying upon, and
has not relied upon, any statement, representation or warranty made by any person, firm or corporation (including, without limitation, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees,
partners, agents or representatives of any of the foregoing), other than the SEC Reports and the statements, representations and warranties of KVSA expressly contained in this Subscription Agreement, in making its investment or decision to invest in
KVSA. The Investor acknowledges and agrees that none of (i) any other investor pursuant to any Other Subscription Agreements relating to the PIPE Investment (including such other investor’s affiliates or any control persons, officers,
directors, employees, partners, agents or representatives of any of the foregoing), (ii) the Placement Agents, their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the
foregoing, (iii) any other party to the Transaction Agreement (other than KVSA), or (iv) any affiliates, or any control persons, officers, directors, employees, partners, agents or representatives of any of the Company or any other party
to the Transaction Agreement (other than KVSA) shall be liable to the Investor, or to any other investor, pursuant to this Subscription Agreement or any Other Subscription Agreement related to the PIPE Investment, the negotiation hereof or thereof
or the subject matter hereof or thereof, or the transactions contemplated hereby or thereby, for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares, including, without
limitation, with respect to 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 by the Company, the Placement Agents or any Non-Party Affiliate concerning the Company, the Placement Agents, any of their affiliates, this Subscription Agreement
or the transactions contemplated hereby. For purposes of this Subscription Agreement, “Non-Party Affiliates” means each former, current or future officer, director, employee, partner, member,
manager, direct or indirect equityholder or affiliate of the Company, the Placement Agent or any of KVSA’s, the Company’s or the Placement Agents’ respective affiliates or any family member of the foregoing. 

13. Press Releases. KVSA shall, by 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 furnish or file with the SEC a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing, to the extent not
previously publicly disclosed, the PIPE Investment, all material terms of the Transaction and any other material, non-public information that KVSA or its directors, officers, employees, agents or
representatives have provided to the Investor or any of its affiliates, or their respective directors, officers, employees, agents or representatives, at any time prior to the filing of the Disclosure Document. From and after the disclosure of the
Disclosure Document, to the knowledge of KVSA, the Investor and its affiliates and their respective directors, officers, employees, agents or representatives shall not be in possession of any material,
non-public information received from KVSA or any of its officers, directors, employees, agents or representatives. All press releases or non-internal communications
relating to the transactions contemplated hereby between KVSA and the Investor, and the method of the release for publication thereof, shall be subject to the prior approval of (i) KVSA, and (ii) to the extent such press release or public
communication references the Investor or its affiliates or investment manager, general partner, managing member or related parties by name, trademark or logo, the Investor; provided that neither KVSA nor the Investor shall be required to
obtain consent pursuant to this Section 13 to the extent any proposed release or statement is substantially equivalent to the information that has previously been made public without breach of the obligation under this
Section 13. The restriction in this Section 13 shall not apply to the extent the non-internal announcement is required by applicable securities law, any
governmental authority or stock exchange rule; provided, that in such an event, the applicable party shall use its commercially reasonable efforts to consult with the other party in advance as to its form, content and timing. Notwithstanding
anything in this Subscription Agreement to the contrary, KVSA shall use reasonable efforts to not, and shall use reasonable efforts to cause each of its directors, officers, employees, agents and representatives to not, provide the Investor with any
material non-public information regarding KVSA from and after the filing of the Disclosure Document with the SEC without the express prior written consent of the Investor. KVSA understands and confirms that
the Investor and the Investor’s affiliates, attorneys, agents or representatives will rely on the foregoing representations and covenants in effecting transactions of securities in KVSA.
