As Representative of the Underwriters
named on Schedule A hereto

Ladies and Gentlemen:

The undersigned, Berto Acquisition Corp. II, a Cayman Islands exempted company (the “Company”), hereby confirms its agreement with Needham & Company, LLC (the “Representative”) and with the other underwriters named on Schedule A hereto (if any), for which the Representative is acting as representative (the Representative and such other underwriters being collectively referred to herein as the “Underwriters” or, each underwriter individually, an “Underwriter,” provided that, if only the Representative is listed on such Schedule A, any references to Underwriters shall refer exclusively to the Representative) as follows:

1. Purchase and Sale of Securities.

1.1 Firm Securities.

1.1.1 Purchase of Firm Units. On the basis of the representations and warranties contained herein, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the several Underwriters, severally and not jointly, and the Underwriters agree to purchase from the Company, severally and not jointly, an aggregate of 25,000,000 units (the “Firm Units”) of the Company, as set forth opposite the respective names of the Underwriters on Schedule A hereto, at a purchase price of $9.96 per Firm Unit. The Firm Units are to be offered initially to the public (the “Offering”) at the offering price of $10.00 per Firm Unit. Each Firm Unit consists of one (1) ordinary share, $0.0001 par value per share (“Ordinary Share”), of the Company (the “Public Shares”), and one-third of one redeemable warrant (each a “Public Warrant” and, collectively with the redeemable warrants included in the Option Units (as defined in Section 1.2.1) and the Placement Warrants (as defined in Section 1.4.2), the “Warrants”). The Ordinary Shares and the Public Warrants included in the Firm Units will trade separately on the fifty-second (52nd) day following the date hereof (or if such date is not a Business Day (as defined in Section 1.1.2), the following Business Day) unless the Representative determines to allow earlier separate trading. Notwithstanding the immediately preceding sentence, in no event will the Ordinary Shares and the Public Warrants included in the Firm Units trade separately until (i) the Company has filed with the Securities and Exchange Commission (the “Commission”) a Current Report on Form 8-K that includes an audited balance sheet reflecting the Company’s receipt of the gross proceeds of the Offering and the Warrant Private Placement (as defined in Section 1.4.2) and updated financial information with respect to any proceeds the Company receives from the exercise of the Over-allotment Option (as defined in Section 1.2.1) if such option is exercised prior to the filing of the Current Report on Form 8-K, and (ii) the Company has issued a press release announcing when such separate trading will begin. Each whole Warrant entitles its holder to purchase one Ordinary Share for $11.50 per share, subject to adjustment, at any time commencing 30 days after the consummation by the Company of a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”), and expiring on the five year anniversary of the consummation by the Company of its initial Business Combination (such consummation, the “Business Combination Closing”), or earlier upon redemption of the Warrants or liquidation of the Company.

1.1.2 Adjustment of Purchase Price. The purchase price per Firm Unit set forth in Section 1.1.1 is subject to adjustment based on the final number of Firm Units to be purchased by the Underwriters hereunder. The aggregate upfront underwriting discount (the “Upfront Underwriting Discount”) represented by the difference between the public offering price of $10.00 per Firm Unit and the purchase price per Firm Unit shall be $1,000,000 if the number of Firm Units is 25,000,000 (as reflected in Section 1.1.1) and $1,170,000 if the number of Firm Units is 30,000,000 (resulting in a purchase price of $9.961 per Firm Unit). If the final number of Firm Units is other than 25,000,000 or 30,000,000, the Upfront Underwriting Discount shall be calculated by linear interpolation between the two foregoing reference points. Schedule E hereto sets forth illustrative calculations of the Upfront Underwriting Discount and the corresponding purchase price per Firm Unit at various Firm Unit levels. For the avoidance of doubt, all references to the purchase price per Firm Unit in this Agreement shall be deemed to refer to the purchase price as so adjusted pursuant to this Section 1.1.2.

1.1.3 Payment and Delivery. Delivery and payment for the Firm Units shall be made at 10:00 a.m., New York City time, on the first (1st) Business Day (as defined below) following the commencement of trading of the Firm Units, or at such earlier time as shall be agreed upon by the Representative and the Company, at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., counsel to the Underwriters (“Mintz”), or at such other place as shall be agreed upon by the Representative and the Company. The hour and date of delivery and payment for the Firm Units are called the “Closing Date.” Payment for the Firm Units shall be made on the Closing Date by wire transfer in Federal (same day) funds, payable as follows: $250,000,000 of the proceeds received by the Company for the Firm Units and the sale of the Placement Warrants shall be deposited in the trust account (the “Trust Account”) established by the Company for the benefit of the Public Shareholders (as defined below), as described in the Registration Statement (as defined in Section 2.1.1) pursuant to the terms of an Investment Management Trust Agreement (the “Trust Agreement”) between the Company and Continental Stock Transfer & Trust Company (“Continental”). The funds deposited in the Trust Account shall include an aggregate of $9,750,000 ($0.39 per Firm Unit), up to which amount shall be payable to the Underwriters as Deferred Underwriting Commission in accordance with Section 1.3 hereof. The remaining proceeds received by the Company for the Firm Units and the sale of the Placement Warrants (less commissions and actual expense payments or other fees payable pursuant to this Agreement), if any, shall be paid to the order of the Company upon delivery to the Representative of certificates (in form and substance satisfactory to the Representative) representing the Firm Units (or through the facilities of The Depository Trust Company (“DTC”)) for the account of the Underwriters. The Firm Units shall be registered in such name or names and

in such authorized denominations as the Representative may request in writing at least two (2) full Business Days prior to the Closing Date. If delivery is not made through the facilities of DTC, the Company will permit the Representative to examine and package the Firm Units for delivery, at least one (1) full Business Day prior to the Closing Date. The Company shall not be obligated to sell or deliver any of the Firm Units except upon tender of payment by the Representative for all the Firm Units. The Representative may, at its option, delegate one of the other Underwriters (with such Underwriter’s consent) to take delivery of the Firm Units and the Option Units and to make payment therefor as set forth above and below. As used herein, the term “Public Shareholders” means the holders of Ordinary Shares sold as part of the Units in the Offering or acquired in the aftermarket, including the Sponsor (as defined in Section 1.4.1) and any officer or director of the Company, to the extent, he, she or it acquires such Ordinary Shares in the aftermarket (and solely with respect to such Ordinary Shares). “Business Day” means any day other than a Saturday, Sunday or other day on which commercial banks in the City of New York are authorized or required by law to remain closed; provided, however, that for clarification, commercial banks shall not be deemed to be authorized or required by law to remain closed due to “stay at home,” “shelter-in-place,” “non-essential employee” or any other similar orders or restrictions or the closure of any physical branch locations at the direction of any governmental authority so long as the electronic funds transfer systems (including for wire transfers) of commercial banks in the City of New York are generally open for use by customers on such day.

1.2 Over-Allotment Option.
