Capitalized terms used herein but not specifically defined herein shall have the meanings ascribed to them in the Financing Agreement.

The Borrowers and the Origination Agent hereby agree that this letter agreement amends and restates the Existing Fee Letter in its entirety.

1. Origination Fee. On the Effective Date, the Borrowers shall pay to the Origination Agent, a non‑refundable origination fee (the “Origination Fee”) equal to $6,250,000, which shall be deemed fully earned when paid.

2. Continuing Origination Agent Services Fee. In consideration for its (i) services in arranging and underwriting the financing facility pursuant to the Financing Agreement and (ii) continuing services as Origination Agent, in its capacity as Origination Agent under the Loan Documents, from the Effective Date until the occurrence of a Trigger Event (such services set forth in clauses (i) and (ii) and more fully described in Schedule A attached hereto, collectively, the “Continuing Origination Agent Services”), the Borrowers shall pay to the Origination Agent an additional fee (the “Continuing Origination Agent Services Fee”), separate and distinct from the Origination Fee, equal to the sum of the incremental amounts of Annual Run Rate Revenue (as defined below) multiplied by the ‘Multiplier’ set forth in the table below for such incremental amount of Annual Run Rate Revenue:

Annual Run Rate Revenue	Multiplier	Formula Used to Determine Multiplier*
$0 - $208,000,000	0	0
Greater than $208,000,000 and less than or equal to $300,000,000	0.1410	4.70% x 3
Greater than $300,000,000 and less than or equal to $500,000,000	0.1008	3.36% x 3
Greater than $500,000,000 and less than or equal to $700,000,000	0.0606	2.02% x 3
Greater than $700,000,000	0.0201	0.67% x 3

* The last column is included solely for informational purposes, and is not part of the calculation of the actual Continuing Origination Agent Services Fee.

The Continuing Origination Agent Services Fee shall be due and payable upon the occurrence of a Trigger Event but if and only if, as of such date, the Origination Agent has performed the Continuing Origination Agent Services. Upon fulfillment of the condition described in the immediately preceding sentence, the Continuing Origination Agent Services Fee shall become immediately earned and shall be deemed to be fully non-refundable when paid. For purposes of this letter agreement, “Trigger Event” means the earliest of (a) the Final Maturity Date, (b) the Termination Date, (c) the acceleration of the Obligations in accordance with Section 9.01 of the Financing Agreement, including as a result of the commencement of an Insolvency Proceeding, (d) the satisfaction, release, payment, restructuring, reorganization, replacement, reinstatement, defeasance or compromise of any of the Obligations in any Insolvency Proceeding, foreclosure (whether by power of judicial proceeding or otherwise) or deed in lieu of foreclosure or the making of a distribution of any kind in any Insolvency Proceeding to the Collateral Agent, for the account of the Lenders in full or partial satisfaction of the Obligations and (e) the termination of the Financing Agreement for any reason. Notwithstanding the foregoing, the Origination Agent may, in its sole discretion, agree to receive payment of the Continuing Origination Agent Services Fee in one or more installments or in a combination of cash and/or Equity Interests. The parties hereto hereby agree that the Continuing Origination Agent Services Fee is a Specified Fee.

Example of Continuing Origination Agent Services Fee calculation: $325,000,000 in Annual Run Rate Revenue at the time of payment of the Continuing Origination Agent Services Fee shall result in a Continuing Origination Agent Services Fee calculated as follows:

(0.1410 * $300,000,000) + (0.1008 * $25,000,000) = $44,820,000.

As used above, “Annual Run Rate Revenue” shall mean the annual run-rate revenue of the Parent and its Subsidiaries, calculated at the time the Continuing Origination Agent Services Fee is due and payable based on the most recently ended fiscal quarter of the Parent multiplied by 4, as certified to the Origination Agent by the Parent and accompanied by detail reasonably acceptable to the Origination Agent.

Notwithstanding the foregoing, the Borrowers and the Origination Agent hereby acknowledge and agree that from and after the date the aggregate outstanding principal amount of the Term Loan is less than $52,000,000 the Continuing Origination Agent Services Fee shall cease to continue to accrue additional amounts, but shall otherwise be due and payable in accordance with the terms set forth herein.

3. Borrower Tax Treatment. The Borrowers hereby agree that for U.S. federal (and corresponding state or local) income tax purposes the relevant Borrower shall not claim a deduction for the Continuing Origination Agent Services Fee prior to the relevant Borrower’s taxable year that includes a Trigger Event, and that in no event shall any such deduction be claimed prior to the time at which the Origination Agent has performed the Continuing Origination Agent Services.

4. Loan Servicing Fee. From and after the Effective Date and until the Termination Date, the Borrowers shall pay to the Origination Agent, a non-refundable loan servicing fee (the “Loan Servicing Fee”) equal to $395,000 per annum, which shall be deemed to be fully earned when paid and which shall be due and payable on the Effective Date and annually in advance thereafter on each anniversary of the Effective Date.

5. Collateral Monitoring Fee. From and after the Effective Date and until the Termination Date, the Borrowers shall pay to the Origination Agent, a non-refundable collateral monitoring fee (the “Collateral Monitoring Fee”) equal to the sum of (i) 2.50% per annum multiplied by (ii) the aggregate outstanding principal amount of the Term Loan (including the Term Loan PIK Amount), which shall be deemed to be fully earned when paid and which shall be due and payable monthly in arrears on the first Business Day of each month after the Effective Date.
