1400 Old Country Road, Suite 301

Westbury, NY 11590

Ladies and Gentlemen:

This Subscription Agreement (this “Subscription Agreement”) is entered into this [•] day of [•], 2022, by and between Kensington Capital Acquisition Corp. IV, a Cayman Islands exempted company, which pursuant to and upon closing of the Transaction Agreement (as defined below), will be domesticated from the Cayman Islands to Delaware and be renamed “Amprius Technologies, Inc.” (such entity, the “Company”), and the undersigned (the “Subscriber”).

The Company entered into a Business Combination Agreement dated as of May 11, 2022 (as it may be amended, restated, waived or otherwise modified from time to time, the “Transaction Agreement”), by and among the Company, Kensington Capital Merger Sub Corp., a Delaware corporation (“Merger Sub”); and Amprius Technologies, Inc., a Delaware corporation (“Amprius”).

In connection with the proposed business combination (the “Transaction”) to be effectuated pursuant to the Transaction Agreement, the Company is seeking commitments to purchase, immediately following the Domestication, (i) shares of common stock, par value $0.0001 per share, of the Company (into which the Company’s Class A ordinary shares, par value $0.0001 per share, are being converted in connection with the Domestication) (any Class A ordinary shares or shares of common stock of the Company, “Shares”), and (ii) an equivalent number of redeemable warrants to purchase Shares at an exercise price of $12.50 (the “Warrants”), which will be governed by that certain warrant agreement by and between the Company and Continental Stock Transfer & Trust Company (“Continental”), as warrant agent, in substantially the form attached hereto as Exhibit A (the “Warrant Agreement”). One Share and one Warrant, collectively, are referred to herein as a “PIPE Security”. Each PIPE Security shall be sold for a purchase price of $10.00 (the “Per Security Price” and the aggregate of such Per Security Price for all PIPE Securities subscribed for by the undersigned being referred to herein as the “Subscription Price”). The Shares being acquired by the Subscriber under this Subscription Agreement, together with the Shares underlying the Warrants, are referred to herein as the “Subscriber Shares”.

On even date herewith, certain other “accredited investors” (each, an “Other Subscriber”) (as defined in Rule 501 under the Securities Act of 1933, as amended (the “Securities Act”)) have entered into separate subscription agreements with the Company (the “Other Subscription Agreements”), pursuant to which, among other things, such investors have, severally and not jointly, together with the undersigned pursuant to this Subscription Agreement, agreed to subscribe for and accept in a private placement an aggregate of [•] PIPE Securities, each PIPE Security (collectively, the “Offering”), together, being sold at the Per Security Price (each such investor, including each of the undersigned, a “Subscriber,” and together, the “Subscribers”).

In connection therewith, the undersigned and the Company agree as follows:

1. Subscription. Subject to the terms and conditions of this Subscription Agreement, the undersigned hereby, severally and not jointly, irrevocably subscribes for and agrees to acquire from the Company such number of PIPE Securities as is set forth on its signature page of this Subscription Agreement on the terms and subject to the conditions provided for herein (the “Subscriber Securities”). The undersigned understands and agrees that the Company reserves the right to accept or reject the undersigned’s subscription for the Subscriber Securities for any reason or for no reason, in whole or in part, at any time prior to its acceptance by the Company, and the same shall be deemed to be accepted by the Company only when this Subscription Agreement is signed by a duly authorized person by or on behalf of the Company; the Company may do so in counterpart form. In the event of rejection of a portion of the subscription by the Company, the undersigned’s payment hereunder will be promptly returned to the undersigned in proportion to the rejected portion of the subscription. In the event of rejection of the entire subscription by the Company or the termination of this subscription in accordance with the terms hereof, the undersigned’s payment hereunder will be returned promptly to the undersigned along with this Subscription Agreement, and this Subscription Agreement shall be null and void and have no force or effect.

2. Closing. The closing of the issuance of the Subscriber Securities contemplated hereby (the “Subscription Closing”) is contingent upon the substantially concurrent consummation of the Transaction (the “Transaction Closing”). The Subscription Closing shall occur on the date of, and immediately prior to, the consummation of the Transaction Closing (the “Transaction Closing Date”). Not less than five (5) business days prior to the scheduled Transaction Closing Date, the Company shall provide written notice to the undersigned (the “Closing Notice”) (i) of such scheduled Transaction Closing Date, (ii) that the Company reasonably expects all conditions to the Transaction Closing to be satisfied or waived, and (iii) wire instructions for delivery of the Subscription Price by the undersigned to the Escrow Agent (as defined below) or the Company, as applicable. The undersigned shall deliver to Continental Stock Transfer & Trust Company, as escrow agent (the “Escrow Agent”), at least two (2) business days prior to the Transaction Closing Date specified in the Closing Notice, the Subscription Price, which shall be held in a segregated escrow account for the benefit of the Subscribers (the “Escrow Account”) until the Subscription Closing pursuant to the terms of a customary escrow agreement, which shall be on terms and conditions reasonably satisfactory to the undersigned (the “Escrow Agreement”) to be entered into by the undersigned, the Company and the Escrow Agent, by wire transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice; provided, however, that in the event the undersigned is not legally permitted to deliver the Subscription Price in accordance with this sentence or is otherwise expected by its primary regulator to deliver payment against delivery of the Subscriber Securities, the undersigned shall instruct its custodian bank to deliver to the Company, by 9:00 a.m. (New York time) on the Transaction Closing Date, the

2

Subscription Price by wire transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice. The Company shall, (i) on the Transaction Closing Date, upon satisfaction (or, if applicable, waiver) of the conditions set forth in Section 3 hereof, issue to the undersigned the Subscriber Securities in book-entry form, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws as set forth herein), in the name of the undersigned (or its nominee in accordance with its delivery instructions) or to a custodian designated by the undersigned, as applicable, and (ii) as promptly as practicable following the Subscription Closing, deliver to the Subscriber a copy of the records of the Company’s transfer agent (the “Transfer Agent”) showing the undersigned (or such nominee or custodian) as the owner of the Subscriber Securities on and as of the Transaction Closing Date; provided that, (x) if such book entry is made prior to the Company’s receipt of the Subscription Price from the undersigned and (y) such Subscription Price is not received by the Company on the Transaction Closing Date, then without limiting any rights of any party under this Subscription Agreement, the Company may, without any action of the undersigned, cause such book entries to be automatically cancelled, void and of no further force and effect. If the Transaction Closing does not occur within two (2) business days of the transaction closing date specified in the Closing Notice, the Escrow Agent (or the Company, as applicable) shall promptly (but not later than one (1) business day thereafter) return the Subscription Price to the undersigned by wire transfer of U.S. dollars in immediately available funds to the account specified by the undersigned. Furthermore, if the Transaction Closing does not occur on the same day as the Subscription Closing, the Escrow Agent (or the Company, if the Subscription Price has been released by the Escrow Agent or if the Subscription Price was paid directly to the Company) shall promptly (but not later than one (1) business day thereafter) return the Subscription Price to the undersigned by wire transfer of U.S. dollars in immediately available funds to the account specified by the undersigned, and any book-entries and, if applicable, certificated shares, shall be deemed cancelled (and, in the case of certificated shares, the undersigned shall promptly return such certificates to the Company, or as directed by the Company, to the Company’s representative or agent). Notwithstanding such return, (i) a failure to close on the anticipated transaction closing date shall not, by itself, be deemed to be a failure of any of the conditions to Subscription Closing set forth in Section 3 to be satisfied or waived on or prior to the Subscription Closing, and (ii) the undersigned shall remain obligated (A) to redeliver funds to the Company following the Company’s delivery of a new Closing Notice and (B) to consummate the Subscription Closing upon satisfaction of the conditions set forth in Section 3.

Notwithstanding anything to the contrary in Section 9 hereof, if this Subscription Agreement terminates following the delivery by the undersigned of the Subscription Price for the Subscriber Securities, the Escrow Agent (or the Company, if the Subscription Price was paid directly to the Company) shall promptly (but not later than one (1) business day thereafter) return the Subscription Price to the undersigned by wire transfer of U.S. dollars in immediately available funds to the account specified by the undersigned, without any deduction for or on account of any tax, withholding, charges, or set-off, whether or not the Transaction Closing shall have occurred. Notwithstanding anything to the contrary in Section 9 hereof, if this Subscription Agreement terminates following the Transaction Closing, the undersigned shall promptly upon

3

the return to the undersigned by wire transfer of U.S. dollars in immediately available funds to the account specified by the undersigned, without any deduction for or on account of any tax, withholding, charges, or set-off of the Subscription Price by the Escrow Agent or the Company, as applicable, transfer and deliver (and execute and deliver or cause to be executed and delivered such additional documents and instruments and take such further action as may be reasonably necessary to effectuate such transfer and delivery of) the Subscriber Securities to the Company.

e. The compliance by the Company with all of the provisions of this Subscription Agreement and the consummation of the transactions herein will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company are subject, which would have a material adverse effect on the business, properties, financial condition, stockholders’ equity or results of operations of the Company (a “Company Material Adverse Effect”) or materially affect the legal authority of the Company to comply in all material respects with the terms of this Subscription Agreement; (ii) result in any violation of the provisions of the organizational documents of the Company; 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 the Company or any of its properties that would have a Company Material Adverse Effect or materially affect the validity of the Subscriber Securities or the legal authority of the Company to comply in all material respects with this Subscription Agreement.

g. The Company has not received any written communication from a governmental entity that alleges that the Company 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 be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect.

None of the SEC Documents contained, when filed or, if amended (such amendment to be deemed to supersede the applicable prior filings), as of the date of such amendment with respect to those disclosures that are amended, any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that with respect to the information about the Company’s affiliates contained in the Proxy Statement (as defined below in Section 11.o) or any other SEC Document, the representation and warranty in this sentence is made to the Company’s knowledge.

As of the date of this Subscription Agreement, the undersigned does not have, and since May 12, 2022, the undersigned has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or Short Sale positions with respect to the securities of the Company. For purposes of this Subscription Agreement, “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 on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing, in case the undersigned is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets, the representation set forth above in this paragraph shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscriber Securities covered by this Subscription Agreement.

p. If the undersigned is a resident of Canada, the undersigned hereby declares, represents, warrants and agrees as set forth in the attached Schedule B.

q. The Subscriber acknowledges and agrees that the Company continues to review the SEC Guidance and its implications, including on the financial statements and other information included in its SEC Documents, and any restatement, revision or other modification of the SEC Documents relating to or arising from such review, any subsequent related agreements or other guidance from the Staff of the SEC shall be deemed not material for purposes of Section 5.i.

14

r. The Subscriber, when required to deliver payment to the Company pursuant to Section 2 above, will have sufficient funds to pay the Subscription Price and consummate the sale, purchase and issuance of the Subscriber Securities pursuant to this Subscription Agreement.

7. Additional Subscriber Agreement. The undersigned hereby agrees that, from the date of this Subscription Agreement and until the Subscription Closing, no person or entity, while acting in connection with this Transaction and on behalf of the undersigned or any of its controlled affiliates or pursuant to any understanding in connection with this Transaction with the undersigned or any of its controlled affiliates, will engage in any Short Sales with respect to securities of the Company. Solely for purposes of this paragraph, subject to the undersigned’s compliance with its obligations under the U.S. federal securities laws and the undersigned’s internal policies, the restrictions set forth above in this paragraph shall not apply to any employees, subsidiaries, desks, groups, or affiliates of the undersigned that are effectively walled off by appropriate “fire wall” information barriers approved by the undersigned’s legal or compliance department. Notwithstanding the foregoing, if the undersigned is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets, this Section 7 shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscriber Securities covered by this Subscription Agreement.

8. Registration Rights.

a. The Company agrees that, within thirty (30) calendar days after the consummation of the Transaction (the “Filing Deadline”), the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Subscriber Shares (including, for the avoidance of doubt, the Shares underlying the Warrants being acquired by the Subscriber, but not the Warrants themselves), and the Company 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) 60 calendar days (or 120 calendar days if the Commission notifies the Company that it will “review” the Registration Statement) following the Filing Deadline, and (ii) five (5) business days after the Company is notified in writing by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”); provided, however, that if the Commission is closed for operations or otherwise operating at reduced capacity due to a government shutdown, the Effectiveness Date shall be extended by the same amount of days that the Commission remains closed for operations or at reduced capacity; provided, further, that the Company’s obligations to include the Subscriber Shares in the Registration Statement are contingent upon the undersigned furnishing in writing to the Company such information regarding the undersigned, the securities of the Company held by the undersigned and the intended method of disposition of the Subscriber Shares, which shall be limited to non-underwritten public offerings, as shall be reasonably requested in writing by the Company to effect the registration of the Subscriber

15

Shares, and the undersigned shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the use of the Registration Statement as permitted hereunder; provided, further, however, that the undersigned 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 Subscriber Shares. With respect to the information to be provided by the undersigned pursuant to this Section 8, the Company shall request such information at least two (2) business days prior to the anticipated initial filing date of the Registration Statement. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of such shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of shares which is equal to the maximum number of shares as is permitted by the Commission. In such event, the number of shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders, and as promptly as practicable after being permitted to register additional shares under Rule 415 under the Securities Act, the Company shall file a new Registration Statement to register such shares (including the Subscriber Shares) not included in the initial Registration Statement and cause such Registration Statement to become effective as promptly as practicable consistent with the terms of this Section 8. In no event shall the undersigned be identified as a statutory underwriter in the Registration Statement unless in response to a comment or request from the staff of the Commission or another regulatory agency; provided, however, that if the Commission requests that the undersigned be identified as a statutory underwriter in the Registration Statement, the undersigned will have an opportunity to withdraw from the Registration Statement, in which case the Company’s obligation to register the Subscriber Shares will be deemed satisfied. The Company will use its commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement until the earliest of (i) the date on which the Subscriber Shares subscribed for by the undersigned hereunder may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(2) (or Rule 144(i)(2), if applicable), (ii) the date on which all Subscriber Shares subscribed for by the undersigned hereunder have actually been sold or otherwise transferred and (iii) the date which is three (3) years after the Subscription Closing (the “Effectiveness Period”). For as long as the Registration Statement shall remain effective pursuant to the immediately preceding sentence, the Company will use commercially reasonable efforts to file all reports, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Subscriber Shares pursuant to the Registration Statement or Rule 144 of the Securities Act (when Rule 144 of the Securities Act becomes available to the undersigned), as applicable, qualify the Subscriber Shares for listing on NYSE, Nasdaq or other applicable stock exchange on which the Shares are then listed, and update or amend the Registration Statement as necessary to include the Subscriber Shares. For purposes of clarification, any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise

16

relieve the Company of its obligations to file or effect the Registration Statement set forth in this Section 8. The undersigned shall not be entitled to use the Registration Statement for an underwritten offering of Subscriber Shares and notwithstanding anything to the contrary in this Subscription Agreement, the Company shall not have any obligation to prepare any prospectus supplement, participate in any due diligence, execute any agreements or certificates or deliver legal opinions or obtain comfort letters in connection with any sales of the Subscriber Shares or any other shares under the Registration Statement. For purposes of this Section 8, “Subscriber Shares” shall mean, as of any date of determination, the Subscriber Shares acquired (or, with respect to the Shares underlying the Warrants, acquirable) by the undersigned pursuant to this Subscription Agreement and any other equity security issued or issuable with respect to such Subscriber Shares by way of stock split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and “undersigned” shall include any affiliate of the undersigned to which the rights under this Section 8 have been duly assigned.

b. In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Subscription Agreement, the Company shall inform the undersigned as to the status of such registration, qualification, exemption and compliance. At its expense the Company shall:

(1) of any request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;

(2) of the issuance by the Commission 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 the Company of any notification with respect to the suspension of the qualification of the Subscriber 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.

Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising the undersigned of such events, provide the undersigned with any material, nonpublic information regarding the Company other than to the extent that providing notice to the undersigned of the occurrence of the events listed in (1) through (4) above constitutes material, nonpublic information regarding the Company;

17

c. Notwithstanding anything to the contrary in this Subscription Agreement, the Company shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business

18

purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Company’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that (x) the Company may not delay or suspend the Registration Statement on more than two (2) occasions, for more than sixty (60) consecutive calendar days, or for more than ninety (90) total calendar days, in each case during any twelve-month period and (y) the Company shall use commercially reasonable efforts to make such registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter. Upon receipt of any written notice from the Company of the happening of any Suspension Event (which notice shall not contain material non-public information other than to the extent that providing notice to the undersigned of the occurrence of the events listed in Section 8(b)(i)(1) through (4) above constitutes material, nonpublic information regarding the Company) 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, each of the undersigned agrees that (i) the undersigned will immediately discontinue offers and sales of the Subscriber Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare during the Effectiveness Period) 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 the Company that the undersigned may resume such offers and sales, and (ii) the undersigned will maintain the confidentiality of any information included in such written notice delivered by the Company except (A) for disclosure to the undersigned’s employees, agents and professional advisers, if any, who need to know such information and are obligated to keep it confidential, and (B) as otherwise required by law or subpoena. If so directed by the Company, the undersigned will deliver to the Company or, in the undersigned’s sole discretion destroy, all copies of the prospectus covering the Subscriber Shares in its possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscriber Shares shall not apply (i) to the extent the undersigned is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

d. Subscriber may deliver written notice (including via email) (an “Opt-Out Notice”) to the Company requesting that Subscriber not receive notices from the Company otherwise required by this Section 8; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless and until subsequently revoked), (i) the Company shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice, and (ii) each time prior to Subscriber’s intended use of an effective registration statement, Subscriber

19

will notify the Company, in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section8.d) and the related suspension period remains in effect, the Company will so notify Subscriber, within one (1) business day of Subscriber’s notification, by delivering to Subscriber a copy of such notice of Suspension Event that would have been provided, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability, and Subscriber shall comply with any restrictions on using such Registration Statement during such Suspension Event.

e. The Company shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless the undersigned (to the extent a seller under the Registration Statement), the officers, directors and employees of each of them, and each person who controls the undersigned (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable and documented attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 7, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding such Subscriber furnished in writing to the Company by such Subscriber expressly for use therein or such Subscriber has omitted a material fact from such information provided, however, that the Company shall not be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished by a Subscriber, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by the Company in a timely manner (to the extent a prospectus was required to be delivered by Subscriber under applicable law), (C) as a result of offers or sales effected by or on behalf of any person by means of a free writing prospectus (as defined in Rule 405 of the Securities Act) that was not authorized in writing by the Company, or (D) in connection with any offers or sales effected by or on behalf of a Subscriber in violation of Section 8.e hereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Subscriber Shares by such Subscriber.

20

f. Each of the undersigned shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, and each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based upon information regarding such Subscriber furnished in writing to the Company by such Subscriber expressly for use therein. In no event shall the liability of any of the undersigned be greater in amount than the dollar amount of the net proceeds received by the undersigned upon the sale of the Subscriber Shares giving rise to such indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Subscriber Shares by such Subscriber.

g. Any person entitled to indemnification pursuant to this Section 8 shall (i) give prompt written notice to the indemnifying party of any claim with respect to which he, she or it seeks indemnification (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 prejudiced the indemnifying party) and (ii) 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 (which consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who 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 legal counsel to any indemnified party a conflict of interest exists 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 for which indemnification could be sought hereunder 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.

h. If the indemnification provided under this Section 8 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses, 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 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,

21

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 this Section 8, any documented 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 8 from any person who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 8.h. shall be individual, not joint and several, and in no event shall the liability of the Subscriber hereunder be greater in amount than the dollar amount of the net proceeds received by the Subscriber upon the sale of the Subscriber Shares giving rise to such indemnification or contribution obligation.

9. Termination. This Subscription Agreement shall terminate and be void and of no further force or 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 (a) such time as the Company notifies the undersigned or publicly discloses that the parties do not intend to consummate the Transaction, (b) such date and time as the Transaction Agreement is terminated in accordance with its terms without the Transaction being consummated, (c) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, or (d) if any of the conditions to the Subscription Closing set forth in Section 3 of this Subscription Agreement are not satisfied or waived on or prior to the Subscription Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated at the Subscription Closing; 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 such breach. The Company shall promptly notify the undersigned of the termination of the Transaction Agreement after the termination of such agreement.

10. Trust Account Waiver. The undersigned acknowledges that the Company is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving the Company and one or more businesses or assets. The undersigned further acknowledges that, as described in the Company’s prospectus relating to its initial public offering dated March 1, 2022 (the “Prospectus”) available at www.sec.gov, substantially all of the Company’s assets consist of the cash proceeds of the Company’s initial public offering and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of the Company, its public stockholders and the underwriters of the Company’s initial public offering. For and in consideration of the Company entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby irrevocably waives any and all right, title and interest, or any claim of any kind the undersigned 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, in each case, as a result of, or arising out of, this Subscription Agreement; provided, that nothing in this Section 10 shall be deemed to limit the undersigned’s right, title, interest or claim to the Trust Account by virtue of the undersigned’s record or beneficial ownership of Shares, if any.

22

d. This Subscription Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. This Subscription Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), by the Company or the Subscriber, respectively, without the prior express written consent of the Subscriber, on the one hand, or the Company and Amprius on the other hand (the consent of Amprius not to be unreasonably withheld, conditioned or delayed), except that (i) this Subscription Agreement and any of the Subscriber’s rights and obligations hereunder may be assigned to any fund or account managed by the same investment manager as the Subscriber or by an “affiliate” (as defined in Rule 12b-2 under the Exchange Act) of such investment manager without the prior consent of the Company or Amprius and (ii) the Subscriber’s rights under Section 8 are deemed to be assigned to an assignee or transferee of the Subscriber Shares (or the Warrants which are exercisable for Subscriber Shares), provided, that such assignee will be deemed to have made each of the representations, warranties and covenants of the Subscriber set forth in Section 6 as of the date of such assignment and as of the Subscription Closing, and no such assignment by the Subscriber will relieve the Subscriber of its obligations under this Subscription Agreement and the Subscriber will remain secondarily liable under this Subscription Agreement for the obligations of the assignee hereunder.

e. This Subscription Agreement shall be binding upon and inure solely to the benefit of each party hereto, and except as otherwise expressly set forth in subsection (q) of this Section 11, nothing in this Subscription Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Subscription Agreement.

All legal actions and proceedings arising out of or relating to this Subscription Agreement shall be heard and determined exclusively in any Supreme Court of the State of New York; provided, however, that if jurisdiction is not then available in the Supreme Court of the State of New York, then any such legal action may be brought in any federal court located in the State of New York or any other New York state court.

Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action arising out of or relating to this Subscription Agreement or the transactions contemplated hereby, (a) any claim that he, she or it is not personally subject to the jurisdiction of the courts in New York as described herein for any reason, (b) that he, she or it or his, her or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the action in any such court is brought in an inconvenient forum, (ii) the venue of such action is improper or (iii) this Subscription Agreement, or the subject matter hereof, may not be enforced in or by such courts.

24

g. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS SUBSCRIPTION AGREEMENT. EACH OF THE PARTIES HERETO (I) CERTIFIES THAT 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 THAT FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT SUCH PARTY AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS SUBSCRIPTION AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.G.
