applicable Due Date, (1) 88% minus (2) the percentage equivalent of a fraction (x) the numerator of which is the aggregate Annualized Run Rate Net Cash Flow for Sites that are subject to a Title Policy or Other Title Policy and (y) the denominator of which is the aggregate Annualized Run Rate Net Cash Flow for all Sites.

“2023-1 Closing Date” means March 13, 2023.

(b)    The parties hereto agree that the following definition in Section 1.01 of the Trust and Servicing Agreement is hereby amended by inserting the text therein which is double underlined in the place where such text appears below:

“Debt Service Coverage Ratio” or “DSCR” as of any date of determination is the Net Cash Flow for the Sites divided by the amount of interest, Servicing Fees, Custodian Fees and Trustee Fees that the Borrowers will be required to pay over the succeeding twelve (12) months on the Principal Amount of the Loan (excluding any Post-ARD Additional Interest, interest on the Components corresponding to any Series of Risk Retention Securities or Value Reduction Accrued Interest), determined without giving effect to any reduction in interest due related to any Value Reduction Amount and determined on a pro-forma basis to exclude Net Cash Flow from any Site that is released from the Collateral.

Section 3.02    Cash Trap Reserve. The parties hereto agree that Section 6.5 of the Loan Agreement is hereby amended by inserting the text therein which is double underlined in the place where such text appears below:

If a Cash Trap Condition shall occur, then, from and after the date that it is determined that a Cash Trap Condition has occurred (which shall be based upon the financial reporting required to be delivered pursuant to Section 5.1(A)(ii)) and for so long as such Cash Trap Condition continues to exist, the applicable Cash Trap Percentage of all Excess Cash Flow (except as otherwise expressly provided below) shall be deposited with Lender (or its Servicer or agent) and held in the Central Account in accordance with the terms of the Cash Management Agreement (said funds, together with any interest thereon, the “Cash Trap Reserve”). A “Cash Trap Condition” shall exist (x) at such time as Lender determines that as of the last day of any calendar quarter ending prior to an Anticipated Repayment Date, the Debt Service Coverage Ratio is equal to or less than the Cash Trap DSCR, (y) on the first Due Date immediately following the sixth-month anniversary of the 2023-1 Closing Date, if, as of such day, the aggregate Annualized Run Rate Net Cash Flow for all Sites that are subject to Title Policies or Other Title Policies as of such day equals less than 40% of the aggregate Annualized Run Rate Net Cash Flow for all Sites; provided that, solely with respect to a Cash Trap Condition pursuant to this clause (y), if the Borrowers have used commercially reasonable efforts to obtain such title insurance policies, such Cash Trap Condition will not be deemed to have occurred until the second Due Date immediately following the sixth-month anniversary of the 2023-1

6

Closing Date, or (z) on the first Due Date immediately following the one-year anniversary of the 2023-1 Closing Date, if, as of such day, the aggregate Annualized Run Rate Net Cash Flow for all Sites that are subject to Title insurance Policies or Other Title Policies as of such day equals less than 88% of the aggregate Annualized Run Rate Net Cash Flow for all Sites, and shall continue to exist until (i) in the case of a Cash Trap Condition pursuant to clause (x), the Lender determines that the Debt Service Coverage Ratio exceeds the Cash Trap DSCR for two (2) consecutive calendar quarters, (ii) in the case of a Cash Trap Condition pursuant to clause (y), the first date following the 2023-1 Closing Date on which the aggregate Annualized Run Rate Net Cash Flow for Sites that are subject to Title Policies or Other Title Policies equals greater than or equal to 40% of the aggregate Annualized Run Rate Net Cash Flow for all Sites as of such date and (iii) in the case of a Cash Trap Condition pursuant to clause (z), the first date following the 2023-1 Closing Date on which aggregate Annualized Run Rate Net Cash Flow for Sites that are subject to Title Policies or Other Title Policies equals greater than or equal to 88% of the aggregate Annualized Run Rate Net Cash Flow for all Sites as of such date. Upon the commencement of an Amortization Period, Lender will apply any amounts in the Cash Trap Reserve on the next Due Date in accordance with the terms and conditions of the Trust Agreement, in the manner provided in Section 3.3(a) of the Cash Management Agreement for Available Funds. Any funds on deposit in the Cash Trap Reserve shall continue to be held as additional Collateral in accordance with this Section 6.5. Provided that no Event of Default exists and Lender determines that the Cash Trap DSCR test has been satisfied for two (2) consecutive calendar quarters (as determined above), any funds remaining in the Cash Trap Reserve shall be released to the Borrowers. The existence of a Cash Trap Condition shall be a reasonable determination made by Lender in good faith.
