follows: 


  

	 	(a)	 The below shall be added as Section 21 immediately following the existing Section 20:

each share of Class B Common Stock of the Company, par value $0.0001 per share (the “Class B Common Stock”), shall automatically convert into one share of Class A Common Stock on a one-for-one basis (the “Initial Conversion Ratio”) automatically concurrently with or immediately following the closing of the Business Combination, and
Section 4.3(b)(ii) of the Charter provides that the Initial Conversion Ratio shall be adjusted (the “Adjustment”) in the event that additional shares of Class A Common Stock or equity-linked securities are issued or deemed
issued in excess of the amounts offered in the Company’s initial public offering of securities and related to or in connection with the closing of the initial Business Combination such that the Sponsor and the Insiders shall continue to own 25%
of the issued and outstanding shares of Class A Common Stock after giving effect to such issuance. As of and conditioned upon the Closing (as such term is defined in the Business Combination Agreement), the Sponsor and each Insider hereby
irrevocably relinquishes and waives any and all rights the Sponsor and each Insider has or will have under Section 4.3(b)(ii) of the Charter to receive shares of Class A Common Stock in excess of the number issuable at the Initial
Conversion Ratio upon conversion of the existing Class B Common Stock held by him, her or it, as applicable, in connection with the Closing (as defined in the Business Combination Agreement) as a result of any Adjustment, and, as a result, the
shares of Class B 












 
Common Stock shall convert into shares of Class A Common Stock (or such equivalent security) at Closing (as defined in the Business Combination Agreement) on a
one-for-one basis such that, as a result of such conversion, all outstanding shares of Class B Common Stock shall collectively convert into 5,750,000 shares of
Class A Common Stock, a portion of which shall be subject to earnout in accordance with the Business Combination Agreement and a portion of which shall be subject to forfeiture in accordance with the Founder Holders Forfeiture Agreement (as
defined in the Business Combination Agreement). When used herein, “Business Combination Agreement” means that certain Business Combination Agreement, dated as of July 27, 2020, by and among the Company, the Sponsor, Rush Street
Interactive, LP, a Delaware limited partnership (the “Target”), the sellers set forth on the signatures pages thereto (collectively, the “Sellers”), and Rush Street Interactive GP, LLC, in its capacity as the
Sellers’ Representative thereunder (the “Sellers’ Representative”), as the same may be amended modified, supplemented or waived from time to time.” 

 

	 	(b)	 Section 15 of the Original Sponsor Letter is hereby replaced in its entirety with the following:



 “Except as set forth in the last sentence of this Section 15, nothing in this Letter Agreement
shall be construed to confer upon, or give to, any person or corporation other than the parties hereto any right, remedy or claim under or by reason of this Letter Agreement or any covenant, condition, stipulation, promise or agreement hereof.
Except as set forth in the last sentence of this Section 15, all covenants, conditions, stipulations, promises and agreements contained in this Letter Agreement shall be for the sole and exclusive benefit of the parties hereto and their
successors, heirs, personal representatives and assigns and permitted transferees. Notwithstanding anything to the contrary contained herein, each of the Target and the Sellers’ Representative is an express third party beneficiary of this
Letter Agreement and may directly enforce (including by an action for specific performance, injunctive relief or other equitable relief) each of the provisions set forth in this Letter Agreement as though directly party hereto and thereto;
provided that, to the extent the Business Combination Agreement is terminated for any reason, the Target and the Sellers’ Representative shall no longer be a third party beneficiary of this Letter Agreement for any purposes and shall
have no right to directly enforce (including by an action for specific performance, injunctive relief or other equitable relief) any of the provisions set forth in this Letter Agreement in any respects.” 

 

	2.	 Enforcement Rights. Notwithstanding anything herein to the contrary, but without limiting the last
sentence of Section 1(b) of this Amendment and Agreement, the Sponsor and each Insider acknowledges and agrees that each of the Target and the Sellers’ Representative may directly enforce (including by an action for
specific performance, injunctive relief or other equitable relief) each of the provisions set forth in this Amendment and Agreement.
