(and any interest subsequently earned thereon) is referred to herein as the “Property,” the stockholders for whose benefit the Trustee shall hold the Property are referred herein to as the “Public
Stockholders,” and the Public Stockholders and the Company together are referred to herein as the “Beneficiaries”); and 

WHEREAS, pursuant to the Underwriting Agreement, $7,750,000, or up to $9,377,500 if the Underwriters’ over-allotment option is exercised
in full, of the Property is attributable to deferred underwriting discounts and commissions that may be payable by the Company to the Representative upon the consummation of the Business Combination (as defined below) (the “Deferred
Discount”); and 
 WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth the terms and
conditions pursuant to which the Trustee shall hold the Property. 
 NOW THEREFORE, IT IS AGREED: 

1. Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to: 

(a) Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the
Trustee at JPMorgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) and at a brokerage institution selected by the Trustee that is reasonably satisfactory to the Company; 

(b) Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein; 

(c) In a timely manner, upon the written instruction of the Company, invest and reinvest the Property in United States government securities
within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(2), (d)(3), (d)(4) and (d)(5) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended, which invest only in direct U.S. government treasury obligations, as determined by the Company; it being understood that the Trust Account will
earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder and the Trustee may earn bank credits or other consideration; 












 (d) Collect and receive, when due, all interest or other income arising from the Property,
which shall become part of the “Property,” as such term is used herein; 
 (e) Promptly notify the Company of all communications
received by the Trustee with respect to any Property requiring action by the Company; 
 (f) Supply any necessary information or documents
as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the Trust Account; 

(g) Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when
instructed by the Company to do so; 
 (h) Render to the Company monthly written statements of the activities of, and amounts in, the Trust
Account reflecting all receipts and disbursements of the Trust Account; 
 (i) Commence liquidation of the Trust Account only after and
promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit
B, as applicable, signed on behalf of the Company by its Chief Executive Officer, President, Chief Financial Officer or Chairman of the board of directors (the “Board”) or other authorized officer of the Company (and in
the case of Exhibit A, signed by the Representative), and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including any amounts representing interest earned on the Trust Account, less interest
previously released to, or reserved for use by, the Company in an amount up to $100,000 to pay dissolution expenses (as applicable) and less any other interest released to, or reserved for use by, the Company to pay franchise and income taxes as
provided in this Agreement only as directed in the Termination Letter and the other documents referred to therein, or (y) 15 months after the closing of the Offering (“Termination Date”), if a Termination Letter has not been
received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including any
amounts representing interest earned on the Trust Account, less interest previously released to, or reserved for use by, the Company in an amount up to $100,000 to pay dissolution expenses (as applicable) and less any other interest released to, or
reserved for use by, the Company to pay franchise and income taxes, shall be distributed to the Public Stockholders of record as of such date. The Trustee agrees to serve as the paying agent of record (“Paying Agent”) with
respect to any distribution of Property that is to be made to the Public Stockholders and, in its separate capacity as Paying Agent, agrees to distribute such Property directly to the Company’s Public Stockholders in accordance with the terms
of this Agreement and the Company’s Certificate of Incorporation in effect at the time of such distribution; 
 (j) Upon written
request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C (a “Withdrawal Request”), withdraw from the Trust Account and distribute to the
Company interest in an amount up to $100,000 to pay dissolution expenses and any interest to cover any tax obligation owed by the Company as a result of assets of the Company or any franchise or income taxes of the Company which amount shall be
delivered directly to the Company by electronic funds transfer or other method of prompt payment. Any Withdrawal Request for a distribution to pay a franchise tax shall be accompanied by a copy of the franchise tax bill from the State of Delaware
for the Company and a written statement from the principal financial officer of the Company setting forth the actual amount payable. To the extent there is not sufficient cash in the Trust Account to fulfill a Withdrawal Request, the Trustee shall
liquidate such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution, so long as there is no reduction in the principal amount per share initially deposited in the Trust Account. The Trustee
acknowledges and agrees that no amount in excess of interest income earned on the Property shall be payable from the Trust Account to the Company pursuant to this Section 1(j). A Withdrawal Request shall constitute
presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request; and 












 (k) Upon written request from the Company, which may be given from time to time in a form
substantially similar to that attached hereto as Exhibit D, the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from Public Stockholders properly submitted in
connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of its public shares of Common Stock
if the Company has not consummated an initial Business Combination within such time as is described in Section 1(i) of this Agreement or to allow redemption in connection with an initial Business Combination. The written
request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and 

(l) Not make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i) through
1(k) above. 
 2. Agreements and Covenants of the Company. The Company hereby agrees and covenants to: 

(a) Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, President, Chief Executive
Officer or Chief Financial Officer. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or
telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in
writing; 
 (b) Subject to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against
any and all expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action, suit or other proceeding brought against the Trustee
involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest earned on the Property, except for expenses and
losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding, pursuant to which the Trustee
intends to seek indemnification under this Section 2(b), the Trustee shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the
right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably withheld. The Trustee
shall not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld. The Company may participate in such action with its own counsel; 

(c) Pay the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual administration fee and
transaction processing fee, which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property shall not be used to pay such fees unless and until the Business Combination is consummated. The
Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation of the Offering. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this
Section 2(c) and as may be provided in Section 2(b) hereof; 
 (d) In connection with
any vote of the Company’s stockholders regarding a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination involving the Company and one or more businesses (a “Business
Combination”), provide to the Trustee an affidavit or certificate of the inspector of elections for the stockholder meeting verifying the vote of such stockholders regarding such Business Combination; 

(e) Provide Representative with a copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect
to any proposed withdrawal from the Trust Account promptly after it issues the same; 
 (f) Instruct the Trustee to make only those
distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under this Agreement; and 












 (g) Within four (4) business days after the Underwriters exercise the over-allotment
option (or any portion thereof) or such over-allotment expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount due with respect to such exercise, which shall be up to $9,377,500. 

3. Limitations of Liability. The Trustee shall have no responsibility or liability to: 

(a) Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this
Agreement and that which is expressly set forth herein; 
 (b) Take any action with respect to the Property, other than as directed in
Section 1 hereof, and the Trustee shall have no liability to any third party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct; 

(c) Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of
any kind with respect to, any of the Property unless and until it shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses
incident thereto; 
 (d) Refund any depreciation in principal of any Property; 

(e) Assume that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided
otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee; 
 (f) The
other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and in the Trustee’s best judgment, except for the Trustee’s gross negligence, fraud or
willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee, which counsel may be the Company’s
counsel), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which the
Trustee believes, in good faith and with reasonable care, to be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of
this Agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its prior written
consent thereto; 
 (g) Verify the accuracy of the information contained in the Registration Statement; 

(h) Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as
contemplated by the Registration Statement;

(k) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i),

 4. Trust Account Waiver. The Trustee has no right of
set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the
Trust Account that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under Section 2(b) or
Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account. 












 5. Termination. This Agreement shall terminate as follows: 

(a) If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed and has agreed to become subject
to the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this
Agreement shall terminate; provided, however, that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an
application to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or

 (b) At such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance with the
provisions of Section 1(i) and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except as set forth in Section 2(b). 

6. Miscellaneous. 
 (a)
The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential
information relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained access to such confidential information, or of any change
in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied to it by the Company, including account names, account numbers, and all other identifying information relating to a Beneficiary,
Beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability or expense resulting from any error in
the information or transmission of the funds.

Section 1(i) hereof (which may not be modified, amended or deleted without the affirmative vote of sixty five percent (65%) of the then outstanding shares of Common Stock; provided that an amendment to
Section 1(i) shall also require the consent of the Representative; provided, further that no such amendment will affect any Public Stockholder who has elected to redeem shares of Common Stock in connection
with a stockholder vote to amend this Agreement to extend the Termination Date, and such amendment shall provide for redemption rights), this Agreement or any provision hereof may only be changed, amended or modified (other than to correct a
typographical error) by a writing signed by each of the parties hereto.

Dear Mr. Wolf and Ms. Gonzalez: 

Pursuant to Section 1(i) of the Investment Management Trust Agreement between Phoenix Biotech Acquisition Corp. (the
“Company”) and Continental Stock Transfer & Trust Company (“Trustee”), dated as of [————-] (“Trust Agreement”), this is to advise you that the
Company has entered into an agreement with (“Target Business”) to consummate a business combination with Target Business (“Business Combination”) on or about [insert date]. The Company shall
notify you at least seventy-two (72) hours in advance of the actual date of the consummation of the Business Combination (“Consummation Date”). Capitalized terms used but not
defined herein shall have the meanings set forth in the Trust Agreement. 
 In accordance with the terms of the Trust Agreement, we hereby
authorize you to commence to liquidate all of the assets of the Trust Account and to transfer the proceeds into the trust operating account at JPMorgan Chase Bank, N.A. so that, on the Consummation Date, all of funds held in the Trust Account will
be immediately available for transfer to the account or accounts that the Company shall direct on the Consummation Date. It is acknowledged and agreed that while the funds are on deposit in the trust operating account at JPMorgan Chase Bank, N.A.
awaiting distribution, the Company will not earn any interest or dividends. 
 On the Consummation Date (i) counsel for the Company
shall deliver to you written notification that the Business Combination has been consummated, or will be consummated concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”) and
(ii) the Company shall deliver to you (a) a certificate by the Chief Executive Officer or President, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held, and
(b) a joint written instruction signed by the Company and the Representative with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount from the Trust Account (the “Instruction
Letter”). You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance with the terms of the Instruction Letter. In
the event that certain deposits held in the Trust Account may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in
the Trust Account and be distributed after the Consummation Date to the Company. Upon the distribution of all the funds from the Trust Account, your obligations under the Trust Agreement shall be terminated. 












 In the event that the Business Combination is not consummated on the Consummation Date
described in the notice thereof and we have not notified you on or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall
be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation Date as set forth in the notice as soon thereafter as possible.
