 Exhibit 10.2 

ARCELLX, INC. 
 CHANGE
IN CONTROL AND SEVERANCE AGREEMENT 
 This Change in Control and Severance Agreement (the “Agreement”) is made between
Arcellx, Inc. (the “Company”) and Michelle Gilson (the “Executive”), effective as of the date on which Executive commences employment with the Company (the “Effective Date”). 

This Agreement provides certain protections to the Executive in connection with a change in control of the Company or in connection with the
involuntary termination of the Executive’s employment under the circumstances described in this Agreement. 
 The Company and the
Executive agree as follows: 
 1. Term of Agreement. This Agreement will continue indefinitely until terminated by written consent of
the parties hereto, or if earlier, upon the date that all of the obligations of the parties hereto with respect to this Agreement have been satisfied. 

2. At-Will Employment. The Company and the Executive acknowledge that the Executive’s
employment is and will continue to be at-will, as defined under applicable law. 
 3. Severance
Benefits. 
 (a) Qualifying Non-CIC Termination. On a Qualifying Non-CIC Termination (as defined below), the Executive will be eligible to receive the following payments and benefits from the Company: 

(i) Salary Severance. A single, lump sum payment equal to twelve (12) months of the Executive’s Salary, less applicable
withholdings. 
 (ii) COBRA Coverage. Subject to Section 3(d), the Company will pay the premiums for coverage under COBRA (as
defined below) for the Executive and the Executive’s eligible dependents, if any, at the rates then in effect, subject to any subsequent changes in rates that are generally applicable to the Company’s active employees (the “COBRA
Coverage”), until the earliest of (A) a period of twelve (12) months from the date of the Executive’s termination of employment, (B) the date upon which the Executive (and the Executive’s eligible dependents,
as applicable) becomes covered under similar plans, or (C) the date upon which the Executive ceases to be eligible for coverage under COBRA.

(iii) Prorated Bonus Severance. A single, lump sum payment equal to Executive’s Target Bonus, prorated by multiplying such amount
by a fraction, (x) the numerator of which is the number of days during which Executive was employed with the Company in the calendar year that the Qualifying Non-CIC Termination occurs, and (y) the
denominator of which is three hundred and sixty-five (365). 











 (b) Qualifying CIC Termination. On a Qualifying CIC Termination, the Executive will
be eligible to receive the following payments and benefits from the Company: 
 (i) Salary Severance. A single, lump sum payment
equal to the sum of eighteen (18) months of the Executive’s Salary and 150% of Executive’s Target Bonus, less applicable withholdings. 

(ii) COBRA Coverage. Subject to Section 3(d), the Company will provide COBRA Coverage until the earliest of (A) a period of
eighteen (18) months from the date of the Executive’s termination of employment, (B) the date upon which the Executive (and the Executive’s eligible dependents, as applicable) becomes covered under similar plans, or (C) the
date upon which the Executive ceases to be eligible for coverage under COBRA. 
 (iii) Equity Vesting Acceleration. Vesting
acceleration (and exercisability, as applicable) as to 100% of the then-unvested shares subject to each of the Executive’s then-outstanding compensatory equity awards issued by the Company that are subject to time-based vesting conditions. In
the case of an equity award subject to performance-based vesting conditions, such equity award will be treated as set forth in the applicable agreement evidencing such equity award. 

(c) Termination Other Than a Qualifying Termination. If the termination of the Executive’s employment with the Company Group is
not a Qualifying Termination, then the Executive will not be entitled to receive severance or other benefits. 
 (d) Conditions to
Receipt of COBRA Coverage. The Executive’s receipt of COBRA Coverage is subject to the Executive electing COBRA continuation coverage within the time period prescribed pursuant to COBRA for the Executive and the Executive’s eligible
dependents, if any. If the Company determines in its sole discretion that it cannot provide the COBRA Coverage without potentially violating, or being subject to an excise tax under, applicable law (including, without limitation, Section 2716
of the Public Health Service Act), then in lieu of any COBRA Coverage, the Company will provide to the Executive a taxable monthly payment payable on the last day of a given month (except as provided by the immediately following sentence), in an
amount equal to the monthly COBRA premium that the Executive would be required to pay to continue his or her group health coverage in effect on the date of his or her Qualifying Termination (which amount will be based on the premium rates applicable
for the first month of COBRA Coverage for the Executive and any of eligible dependents of the Executive) (each, a “COBRA Replacement Payment”), which COBRA Replacement Payments will be made regardless of whether the Executive elects
COBRA continuation coverage and will end on the earlier of (x) the date upon which the Executive obtains other employment or (y) the date the Company has paid an amount totaling the number of COBRA Replacement Payments equal to the number
of months in the applicable COBRA Coverage period. For the avoidance of doubt, the COBRA Replacement Payments may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to any applicable
withholdings. Notwithstanding anything to the contrary under this Agreement, if the Company determines in its sole discretion at any time that it cannot provide the COBRA Replacement Payments without violating applicable law (including, without
limitation, Section 2716 of the Public Health Service Act), the Executive will not receive the COBRA Replacement Payments or any further COBRA Coverage.

 (e) Non-Duplication of Payment or Benefits. For purposes of clarity, in
the event of a Qualifying Pre-CIC Termination, any severance payments and benefits to be provided to the Executive under Section 3(b) will be reduced by any amounts that already were provided to the
Executive under Section 3(a). Notwithstanding any provision of this Agreement to the contrary, if the Executive is entitled to any cash severance, continued health coverage benefits, or vesting acceleration of any equity awards (other than
under this Agreement) by operation of applicable law or under a plan, policy, contract, or arrangement sponsored by or to which any member of the Company Group is a party (“Other Benefits”), then the corresponding severance payments
and benefits under this Agreement will be reduced by the amount of Other Benefits paid or provided to the Executive. 
 (f) Death of the
Executive. In the event of the Executive’s death before all payments or benefits the Executive is entitled to receive under this Agreement have been provided, the unpaid amounts will be provided to the Executive’s designated
beneficiary, if living, or otherwise to the Executive’s personal representative in a single lump sum as soon as possible following the Executive’s death. 

(g) Transfer Between Members of the Company Group. For purposes of this Agreement, if the Executive is involuntarily transferred from
one member of the Company Group to another, the transfer will not be a termination without Cause but may give the Executive the ability to resign for Good Reason. 

(h) Exclusive Remedy. In the event of a termination of the Executive’s employment with the Company Group, the provisions of this
Agreement are intended to be and are exclusive and in lieu of any other rights or remedies to which the Executive may otherwise be entitled, whether at law, tort or contract, or in equity. The Executive will be entitled to no benefits, compensation
or other payments or rights upon termination of employment other than those benefits expressly set forth in this Agreement. 
 4. Accrued
Compensation. On any termination of the Executive’s employment with the Company Group, the Executive will be entitled to receive all accrued but unpaid vacation, expense reimbursements, wages, and other benefits due to the Executive under
any Company-provided plans, policies, and arrangements. 
 5. Conditions to Receipt of Severance. 

(a) Separation Agreement and Release of Claims. The Executive’s receipt of any severance payments or benefits upon the
Executive’s Qualifying Termination under Section 3 is subject to the Executive signing and not revoking the Company’s then-standard separation agreement and release of claims (which may include an agreement not to disparage any member
of the Company Group, non-solicit provisions, an agreement to assist in any litigation matters, and other standard terms and conditions) (the “Release” and that requirement, the
“Release Requirement”), which must become effective and irrevocable no later than the sixtieth (60th) day following the Executive’s Qualifying Termination (the
“Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, the Executive will forfeit any right to severance payments or benefits under Section 3. 

  
 - 3 - 












 (b) Payment Timing. Any lump sum payments under Sections 3(a) and 3(b) will be
provided on the first regularly scheduled payroll date of the Company following the date the Release becomes effective and irrevocable (the “Severance Start Date”), subject to any delay required by Section 5(d) below. Any
taxable installments of any COBRA-related severance benefits that otherwise would have been made to the Executive on or before the Severance Start Date will be paid on the Severance Start Date, and any remaining installments thereafter will be
provided as specified in the Agreement. Any restricted stock units, performance shares, performance units, and/or similar full value awards that accelerate vesting under Section 3 will be settled, as applicable (x) on a date no later than
ten (10) days following the date the Release becomes effective and irrevocable, or (y) if later, in the event of a Qualifying Pre-CIC Termination, on a date no later than the Change in Control. 

(c) Return of Company Property. The Executive’s receipt of any severance payments or benefits upon the Executive’s Qualifying
Termination under Section 3 is subject to the Executive returning all documents and other property provided to the Executive by any member of the Company Group (with the exception of a copy of the Company employee handbook and personnel
documents specifically relating to the Executive), developed or obtained by the Executive in connection with his or her employment with the Company Group, or otherwise belonging to the Company Group. 

(d) Section 409A. The Company intends that all payments and benefits provided under this Agreement or otherwise are exempt from, or
comply with, the requirements of Section 409A of the Code and any guidance promulgated under Section 409A of the Code (collectively, “Section 409A”) so that none of the payments or benefits will be
subject to the additional tax imposed under Section 409A, and any ambiguities in this Agreement will be interpreted in accordance with this intent. No payment or benefits to be paid to the Executive, if any, under this Agreement or otherwise,
when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A (together, the “Deferred Payments”) will be paid or otherwise provided until the
Executive has a “separation from service” within the meaning of Section 409A. If, at the time of the Executive’s termination of employment, the Executive is a “specified employee” within the meaning of
Section 409A, then the payment of the Deferred Payments will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under Section 409A, which generally means that the Executive will receive payment on the
first payroll date that occurs on or after the date that is six (6) months and one (1) day following the Executive’s termination of employment. The Company reserves the right to amend this Agreement as it considers necessary or
advisable, in its sole discretion and without the consent of the Executive or any other individual, to comply with any provision required to avoid the imposition of the additional tax imposed under Section 409A or to otherwise avoid income
recognition under Section 409A prior to the actual payment of any benefits or imposition of any additional tax. Each payment, installment, and benefit payable under this Agreement is intended to constitute a separate payment for purposes of
U.S. Treasury Regulation Section 1.409A-2(b)(2). In no event will any member of the Company Group reimburse, indemnify, or hold harmless the Executive for any taxes, penalties and interest that may be
imposed, or other costs that may be incurred, as a result of Section 409A. 
 (e) Resignation of Officer and Director Positions.
The Executive’s receipt of any severance payments or benefits upon the Executive’s Qualifying Termination under Section 3 is subject to the Executive resigning from all officer and director positions with all members of the Company
Group and the Executive executing any documents the Company may require in connection with the same.

 6. Limitation on Payments. 

(a) Reduction of Severance Benefits. If any payment or benefit that the Executive would receive from any Company Group member or
any other party whether in connection with the provisions in this Agreement or otherwise (the “Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but
for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Payment will be equal to the Best Results Amount. The “Best Results Amount” will be either
(x) the full amount of the Payment or (y) a lesser amount that would result in no portion of the Payment being subject to the Excise Tax, whichever of those amounts, taking into account the applicable federal, state and local employment
taxes, income taxes and the Excise Tax, results in the Executive’s receipt, on an after-tax basis, of the greater amount. If a reduction in payments or benefits constituting parachute payments is
necessary so that the Payment equals the Best Results Amount, reduction will occur in the following order: (A) reduction of cash payments in reverse chronological order (that is, the cash payment owed on the latest date following the occurrence
of the event triggering the Excise Tax will be the first cash payment to be reduced); (B) cancellation of equity awards that were granted “contingent on a change in ownership or control” within the meaning of Section 280G of the
Code in the reverse order of date of grant of the awards (that is, the most recently granted equity awards will be cancelled first); (C) reduction of the accelerated vesting of equity awards in the reverse order of date of grant of the awards
(that is, the vesting of the most recently granted equity awards will be cancelled first); and (D) reduction of employee benefits in reverse chronological order (that is, the benefit owed on the latest date following the occurrence of the event
triggering the Excise Tax will be the first benefit to be reduced). In no event will the Executive have any discretion with respect to the ordering of Payment reductions. The Executive will be solely responsible for the payment of all personal tax
liability that is incurred as a result of the payments and benefits received under this Agreement, and the Executive will not be reimbursed, indemnified, or held harmless by any member of the Company Group for any of those payments of personal tax
liability. 
 (b) Determination of Excise Tax Liability. Unless the Company and the Executive otherwise agree in writing, the
Company will select a professional services firm (the “Firm”) to make all determinations required under this Section 6, which determinations will be conclusive and binding upon the Executive and the Company for all purposes.
For purposes of making the calculations required by this Section 6, the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of
Sections 280G and 4999 of the Code. The Company and the Executive will furnish to the Firm such information and documents as the Firm reasonably may request in order to make determinations under this Section 6. The Company will bear the costs
and make all payments for the Firm’s services in connection with any calculations contemplated by this Section 6. The Company will have no liability to the Executive for the determinations of the Firm. 

7. Definitions. The following terms referred to in this Agreement will have the following meanings:

provided that, with respect to any of the foregoing, the Board shall be required to give the Executive written notice of any termination for “Cause”

a thirty (30) day ability to cure any such conduct, unless such conduct is non-curable. 
 (c)
“Change in Control” means the occurrence of any of the following events: 
 (i) A change in the ownership of the Company
which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty (50%)
of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection, (A) the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the total
voting power of the stock of the Company will not be considered a Change in Control, and (B) if the stockholders of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in
substantially the same proportions as their ownership of shares of the Company’s voting stock immediately prior to the change in ownership, the direct or indirect beneficial ownership of fifty percent (50%) or more of the total voting power of
the stock of the Company or of the ultimate parent entity of the Company, such event will not be considered a Change in Control under this subsection (i). For this purpose, indirect beneficial ownership will include, without limitation, an interest

majority of members of the Board is replaced during any twelve (12) month period by members of the Board whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election.
For purposes of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or

 For purposes of this definition, persons will be
considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company.

event within the meaning of Section 409A. 
 Further and for the avoidance of doubt, a transaction will not constitute a Change in
Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the
Company’s securities immediately before such transaction.
