(a)    The Company confirms that it has received the Requisite Consent contemplated by Section 2(a) of the First Novator Letter Agreement and the Second Requisite Consent contemplated by Section 4(b) of the Second Novator Letter Agreement (together, the “Prior Requisite Consents”). The Notes held by Novator are exchangeable in accordance with the Exchange, as contemplated by the First Novator Letter Agreement, or the Second Exchange Right, as contemplated by the Second Novator Letter Agreement (the Exchange and the Second Exchange Right together, the “Novator Exchange Rights”).

(b)    In order to facilitate the implementation of the Second Novator Exchange Right in connection with the consummation of the transactions contemplated by the Merger Agreement on or before the Agreement End Date, Novator hereby elects to exchange all of its $100 million aggregate principal amount of Notes for a number of newly-issued shares of Better Home & Finance Class A Common Stock at a price per share that represents a 75%

discount to the Pre-Money Valuation (as defined below) immediately after consummation of the transactions contemplated by the Merger Agreement in satisfaction of its rights under the Prior Novator Letter Agreements (the “Novator Exchange Election”). For purposes of this Section 1(b), the term “Pre-Money Valuation” means the $6.9 billion pre-money equity valuation of the Company based on the aggregate amount of fully diluted shares of Company common stock on an as-converted basis (excluding, for the avoidance of doubt, the Novator Exchange or any conversion of the Notes) as of the date the transactions contemplated by the Merger Agreement are consummated. For the avoidance of doubt, the Novator Exchange Election shall no longer be binding on Novator, its obligations thereunder immediately released and the Novator Exchange Rights unaffected thereby if the transactions contemplated by the Merger Agreement are not consummated on or before September 30, 2023.
