This Amendment of Warrant Agreement (this “Agreement”) is made as of August 15, 2022, by and between Rubicon Technologies, Inc., a Delaware corporation (formerly known as Founder SPAC, a Cayman Islands exempted company) (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation (the “Warrant Agent”).

WHEREAS, the Company and the Warrant Agent are parties to that certain Warrant Agreement, dated as of October 14, 2021 and filed by the Company with the United States Securities and Exchange Commission on October 20, 2021 (the “Existing Warrant Agreement”);

WHEREAS, the terms of the Warrants (as defined in the Existing Warrant Agreement) are governed by the Existing Warrant Agreement and capitalized terms used herein, but not otherwise defined, shall have the meanings given to such terms in the Existing Warrant Agreement;

WHEREAS, on December 15, 2021, the Company, Ravenclaw Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of the Company, Ravenclaw Merger Sub Corporation 1, a Delaware corporation and wholly owned subsidiary of the Company, Ravenclaw Merger Sub Corporation 2, a Delaware corporation and wholly owned subsidiary of the Company, Ravenclaw Merger Sub Corporation 3, a Delaware corporation and wholly owned subsidiary of the Company, Boom Clover Business Limited, a British Virgin Islands corporation, NZSF Frontier Investments Inc., a Delaware corporation, and PLC Blocker A LLC, a Delaware limited liability company, entered into an agreement and plan of merger (the “Merger Agreement”) with Rubicon Technologies, LLC, a Delaware limited liability company;

WHEREAS, pursuant to the Merger Agreement, among other things, the Company deregistered under the Cayman Islands Companies Act (As Revised) and domesticated as a Delaware corporation under Section 388 of the Delaware General Corporation Law (the “Domestication”) and in connection therewith, the Company changed its name from Founder SPAC (“Founder”) to Rubicon Technologies, Inc.;

WHEREAS, immediately following the Domestication, the parties to the Merger Agreement consummated the mergers contemplated thereby;

WHEREAS, as a result of and upon the effective time of the Domestication, among other things, (A) each then-issued and outstanding Class A ordinary share, par value $0.0001 per share, of Founder (“Founder Class A Shares”) automatically converted into one share of Class A common stock, par value $0.0001 per share, of the Company (“Domestication Class A Common Stock”), (B) each then-issued and outstanding Class B ordinary share, par value $0.0001 per share, of Founder converted into one share of Domestication Class A Common Stock pursuant to the Sponsor Agreement, dated December 15, 2021, by and among Founder, Founder SPAC Sponsor LLC, Rubicon Technologies, LLC, and certain insiders of Founder, (C) each then-issued and outstanding public warrant of Founder, each representing a right to acquire one Founder Class A Share for $11.50 (a “Founder Public Warrant”), converted automatically, on a one-for-one basis, into a public warrant of the Company (the “Domestication Public Warrant”) that represents a right to acquire one share of Domestication Class A Common Stock for $11.50 pursuant to Section 4.5 of the Existing Warrant Agreement, (D) each then-issued and outstanding private placement warrant, each representing a right to acquire one Founder Class A Share for $11.50, converted automatically, on a one-for-one basis, into a private placement warrant of the Company that represents a right to acquire one share of Domestication Class A Common Stock for $11.50 pursuant to Section 4.5 of the Existing Warrant Agreement, and (E) each then-issued and outstanding unit of Founder, each representing a Founder Class A Share and one-half of a Founder Public Warrant (a “Founder Unit”), that had not been previously separated into the underlying Founder Class A Share and one-half of one Founder Public Warrant upon the request of the holder thereof, was separated and automatically converted into one share of Domestication Class A Common Stock and one-half of one Domestication Public Warrant. No fractional Domestication Public Warrants were issued upon separation of the Founder Units. In addition, the certificate of incorporation of the Company authorized Class V common stock, par value $0.0001 per share (“Domestication Class V Common Stock”). Domestication Class A Common Stock is entitled to economic rights and one vote per share and Domestication Class V Common Stock is entitled to one vote per share with no economic rights;

WHEREAS, effective as of the Domestication, as provided in Section 4.5 of the Existing Warrant Agreement, the Warrants are no longer exercisable for Founder Class A Shares, but instead are exercisable (subject to the terms and conditions of the Existing Warrant Agreement as amended hereby) for a like number of shares of Domestication Class A Common Stock;

WHEREAS, the consummation of the transactions contemplated by the Merger Agreement constituted a Business Combination (as defined in the Existing Warrant Agreement); and

WHEREAS, Section 9.8 of the Existing Warrant Agreement provides that the Company and the Warrant Agent may amend the Existing Warrant Agreement without the consent of any registered holder (as defined in the Existing Warrant Agreement) for the purpose of, among other things, adding or changing any other provisions with respect to matters or questions arising under the Existing Warrant Agreement as the Company and the Warrant Agent may deem necessary or desirable and that the Company and the Warrant Agent deem shall not adversely affect the interest of the registered holders.
