earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder; while account funds are invested or uninvested, 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; 

  
 1

of all communications received by the Trustee with respect to any Property requiring action by the Company; 
 (f) Supply any necessary

 (g) Participate in any plan or proceeding for

letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B signed on behalf of the Company by its Chief Executive Officer, President, Co-President, Chief Financial Officer, Chief Operating Officer, General Counsel, Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized officer of
the Company, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses and which interest
shall be net of any taxes payable, it being understood that the Trustee has no obligation to monitor or question the Company’s position that an allocation has been made for taxes payable), only as directed in the Termination Letter and the
other documents referred to therein; provided, that, in the case a Termination Letter in the form of Exhibit A is received, or (y) upon the date which is twenty-four (24) months after the closing of the Offering, or such later date
as may be approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, as it may be amended from time to time, 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 interest (less up to
$100,000 of interest that may be released to the Company to pay dissolution expenses and which interest shall be net of any taxes payable), shall be distributed to the Public Shareholders of record as of such date;

Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any tax obligation owed by the
Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward
such payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, 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; provided, further, however, that if the tax to
be paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill for the Company (it being acknowledged and agreed that any such amount in excess of interest income
earned on the Property shall not be payable from the Trust Account). The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility
to look beyond said request; 
 (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 (a “Shareholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem Ordinary Shares

Company’s obligation to allow redemption in connection with the Company’s initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination involving the Company and one or more businesses (a
“Business Combination”) or to redeem 100% of the Company’s public shares if it does not complete its initial Business Combination within twenty-four (24) months from the closing of the Offering or (B) with
respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity. The written request of the Company referenced above shall constitute presumptive evidence that

intends to seek indemnification under this Section 2(b), it 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 may 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 it is distributed to the Company pursuant to Sections
1(i) through 1(j) hereof. 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;

or document other than this Agreement and that which is expressly set forth herein;

(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; 

  
 3 













 (e) Assume that the authority of any person designated by the Company to give instructions

(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 with written notification to the Company, 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;

authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

(j) Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and
activities relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, franchise and income tax obligations, except pursuant to Section 1(j) hereof; or 

(k) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i),
1(j) or 1(k) hereof. 
 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 (whether following the Trustee giving notice that it desires to resign under this Agreement or the Company otherwise electing to replace the Trustee under 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; 

(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) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to Section 2(b); or 

(c) If the Offering is not consummated within ten (10) business days of the date of this Agreement, in which case any funds received by
the Trustee from the Company or Blue Whale Sponsor I LLC for purposes of funding the Trust Account shall be promptly returned to the Company or Blue Whale Sponsor I LLC, as applicable.

 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,

shares, par value $0.0001 per share, of the Company voting together as a single class; provided that no such amendment will affect any Public Shareholder who has otherwise indicated his, her or its election to redeem his, her or its Ordinary Shares
in connection with a shareholder vote sought to amend this Agreement), 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.

 Re: Trust Account—Termination Letter 

Dear Mr. Wolf and Ms. Gonzalez: 
 Pursuant to

“Trustee”), dated as of [•], 2021 (the “Trust Agreement”), this is to advise you that the Company has entered into an agreement with (the “Target Business”) to consummate a
merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with the Target Business (the “Business Combination”) on or about [insert date]. The Company shall notify you at
least seventy-two (72) hours in advance of the actual date (or such shorter time period as you may agree) 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 above-referenced trust operating account at J.P. Morgan Chase Bank, N.A. to the effect that, on the
Consummation Date, all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that Goldman Sachs & Co. LLC and BofA Securities, Inc. (the “Representatives”) (with
respect to the Deferred Discount) and 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 J.P. Morgan Chase Bank, N.A. awaiting distribution, neither
the Company nor the Representatives will earn any interest. 
 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 substantially, 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 of the Chief Executive Officer, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders, if a vote is held and (b) joint
written instruction signed by the Company and the Representatives 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, net of any payments necessary for reasonable unreimbursed expenses related to liquidating 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.
