(the “Lender”) has approved the establishment of, a loan authorization account (“Loan Account”) from which the Fund may from time to time request loans in an aggregate amount of up to the maximum amount of credit shown below (the “Amount of Maximum Credit”). Interest on such loans is computed at a variable rate which may change daily based upon changes in the Prime Rate or the SOFR Quoted Rate (each hereinafter defined). The Fund may make principal payments at any time and in any amount without premium or penalty. The request by the Fund for, and the making by the Lender of, any loan against the Loan Account shall constitute an agreement between the Fund and the Lender as follows: Name of Fund: New Mountain Guardian IV Income Fund, L.L.C., a Delaware limited liability company (the “Fund”).

Variable Interest Rate: The interest rate applicable prior to the Maturity Date equals the greater of (i) the rate per -2- annum announced by the Lender from time to time as its prime commercial rate (the “Prime Rate”) minus 0.25% per annum (the “Prime Rate Margin”) or (ii) the SOFR Quoted Rate for such day plus the rate of 2.50% per annum (the “SOFR Margin”). As used herein, the term “Term SOFR” means a rate equal to the secured overnight financing rate as administered by the Term SOFR Administrator; the term “SOFR Quoted Rate” means, as of any day of determination, 3-month Term SOFR on the date that is two U.S. Government Securities Business Days prior to such day of determination as such rate is published by the Term SOFR Administrator plus a credit spread adjustment of 0.15%; provided, that in no event shall the “SOFR Quoted Rate” be less than 0.00%; the term “Term SOFR Administrator” means the CME Group Benchmark Administration Limited (CBA) (or a successor administrator of the Term SOFR selected by the Lender in its reasonable discretion); and the term “U.S. Government Securities Business Day” means any day except for (i) a Saturday, (ii) a Sunday or (iii) a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in United States government securities.

LN IQ Wire Account Number: 109-535-5 Reference: New Mountain Guardian IV Income Fund, L.L.C. Attn.: Clients Services Dept. 1. Using the Account. All loans and advances from the Loan Account are referred to in this Agreement as “Loans”. Loan requests must be in writing or by telephone and confirmed in writing (including by facsimile or e-mail) and shall be sent to the Fund’s BMO Bank N.A. Account Officer or Client Services Officer no later

-3- than 1:00 p.m. (New York time) on the date of the proposed borrowing in order to be honored the same day. Loan proceeds shall be credited to the Fund’s deposit account at the Lender unless the Lender is directed otherwise by special written directions from the Fund. The amount of each Loan requested shall be at least the Minimum Amount, and the Lender shall have the right to refuse to honor any Loan requested by the Fund which is less than the Minimum Amount, even if the Lender has previously honored a Loan request for less than the Minimum Amount. The Fund shall not request any Loan which, when taken together with the Loans then outstanding, would exceed the Amount of Maximum Credit. Loan proceeds shall be used by the Fund to (i) bridge finance capital calls on the Fund’s Members by the Fund and (ii) finance other permitted uses as outlined in the LLC Agreement. If Loans are secured directly or indirectly by securities traded on a national exchange or by other “margin stock” (as defined by the Federal Reserve Board in Regulation U), then the Fund promises to furnish the Lender a duly executed and completed Form U-1 statement and agrees that the proceeds of Loans from the Loan Account will not be used to purchase or carry margin stock, convertible bonds convertible into margin stock or warrants for margin stock unless the Fund has obtained the prior written consent of the Lender. In no event shall the proceeds of any Loans be utilized to finance participation in a hostile tender offer or similar transaction or to finance an acquisition of securities in anticipation of such a hostile transaction. Loans will be made available from the Loan Account subject to the Lender’s approval on a case-by-case basis as and when Loans are requested by the Fund. All Loans shall be made against and evidenced by the Fund’s promissory note payable to the Lender and its registered assigns, such note to be in the form of Exhibit A attached hereto (the “Note”). The Lender agrees that the Note shall evidence only the actual unpaid principal balance of Loans made under the Loan Account. All Loans made against the Note and the status of all amounts evidenced by the Note shall be recorded by the Lender on its books and records or, at its option in any instance, on a schedule to the Note and the unpaid principal balance and status and rates so recorded by the Lender shall be prima facie evidence in any court or other proceeding brought to enforce the Note of the principal amount remaining unpaid thereon, the status of the Loans evidenced thereby and the interest rates applicable thereto, absent manifest error; provided, that the failure of the Lender to record any of the foregoing shall not limit or otherwise affect the obligation of the Fund to repay the principal amount of the Note together with accrued interest thereon. Subject to Section 17, the Lender agrees that if it transfers or assigns the Note, the Lender will stamp thereon a statement of the actual principal amount evidenced thereby at the time of transfer. The Fund agrees that in any action or proceeding instituted to collect or enforce collection of the Note, the amount shown as owing the Lender on its records shall be prima facie evidence of the unpaid balance of principal and interest on the Note, absent manifest error. 2. Interest. The Fund shall pay the Lender interest on the unpaid principal balance of Loans in accordance with the terms of this Agreement. Accrued interest will be billed monthly, and is payable in arrears on the first Business Day of each month (each, an “Interest Payment Date”) for interest accrued through the last day of the previous month. Interest for each billing period is computed by applying a daily periodic rate based on the greater of (i) the Prime Rate minus the Prime Rate Margin or (ii) the SOFR Quoted Rate plus the SOFR Margin to each day’s ending Loan balance. Interest shall be computed on the basis of a year of 365/366 days for the actual number of days elapsed. The Prime Rate reflects market rates of interest as well as other factors, and it is not necessarily the Lender’s best or lowest rate. The daily Loan balance shall be computed by taking the principal balance of Loans at the beginning of each day, adding any Loans posted to the Loan -4- Account that day, and subtracting any principal payments posted to the Loan Account as of that day. Interest begins to accrue on the date a Loan is posted to the Loan Account. The principal balance of Loans which remains unpaid on the due date therefor (after giving effect to any applicable grace period, including the fifteen (15) Business Day period applicable in the case of a demand for repayment) shall bear interest thereafter until paid in full at a post-maturity rate determined by adding the rate of 2.00% per annum to the interest rate otherwise applicable to the Loans (determined as aforesaid). The interest rate payable under this Agreement shall be subject, however, to the limitation that such interest rate shall never exceed the highest rate which the Fund may contract to pay under applicable law. Interest on the Loans shall, at the option of the Fund and subject to the following terms and conditions, be payable either (i) in immediately available funds on each Interest Payment Date in accordance with this Section 2, or (ii) through a Loan on each Interest Payment Date, or (iii) by any combination of the methods described in the immediately preceding clauses (i) and (ii) selected by the Fund which results in such methods being applied in the satisfaction in full of all interest due on the Loans on such Interest Payment Date: (a) Unless the Fund notifies the Lender by 12:00 noon (New York Time) on the applicable Interest Payment Date that the Fund intends to pay the interest due on the Loans on such Interest Payment Date with funds not borrowed under this Agreement, the Fund shall be deemed to have irrevocably requested a Loan on each Interest Payment Date in the amount of the interest then due on the Loans, in each case subject to the provisions of this Agreement (other than the Minimum Amount requirement), which new Loan shall be applied to pay the interest then due on the Loans. In the event the Fund has elected to pay the interest due on the Loans with funds not borrowed under this Agreement and the Fund fails to make any such payment within twenty (20) days of the applicable Interest Payment Date, the Lender may in its sole discretion deem the Fund to have irrevocably requested a Loan in the amount of the interest then due on the Loans, in each case subject to the provisions of this Agreement (other than the requirement that a Loan be in a Minimum Amount) which new Loans shall be applied to pay the interest then due on the Loans. (b) Each payment of interest by a borrowing of a Loan shall be evidenced by the Note, shall bear interest from the date made at a rate per annum equal at all times to the rate then applicable to the Loans, payable on the Maturity Date therefor. (c) In no event shall the unpaid principal balance of all Loans, including, without limitation, each borrowing of a Loan to pay interest then due on the Loans, exceed the Amount of Maximum Credit. 3. Fees. The Fund agrees to pay to the Lender (a) a closing fee in the amount of $30,000, which shall be due and payable on the date of this AgreementInitial Effective Date, (b) an annual administrative fee in the amount of 0.20% of the Amount of Maximum Credit then in effect, which shall be due and payable on each anniversary of the date of this Agreement until the termination of the Loan Account, and (c) with respect to any exercise of the Accordion Option with respect to an increase in the Amount of Maximum Credit (each, an “Increase”), an increase fee in the amount of 0.20% of the amount of such Increase, which shall be due and payable on the effective date of such Increase. Each of the foregoing fees shall be fully earned when due and payable and non-refundable when paid. 4. Payments. Payments received by the Lender shall be applied first to accrued interest and then to the principal balance of outstanding Loans unless otherwise determined by the Lender. If any payment from the Fund under this Agreement becomes due on a day that is not a Business Day, such payment shall be made on the -5- next Business Day and any such extension shall be included in computing interest under this Agreement. 5. Periodic Statements. The Lender will furnish the Fund with a monthly statement for each billing period which has any transaction or balance (each, a “Periodic Statement”). 6. Financial Statements. The Fund agrees to furnish financial information of the Fund to the Lender upon reasonable request of the Lender from time to time and to the extent reasonably available to the Fund. Such information shall be furnished as soon as reasonably possible, but in any event within thirty (30) days after request by the Lender. Without any such request, the Fund shall deliver to the Lender: (a) as soon as available, and in any event within thirty (30) days after the last day of each fiscal quarter, a certificate as of such date in the form, or substantially the form, of Exhibit B attached hereto; (b) promptly after the same are made available to the Fund’s Members, and in any event within sixty (60) days after the last day of each of the first three fiscal quarters of each fiscal year of the Fund, a copy of the Fund’s balance sheet as of the last day of such fiscal quarter and its statements of income, retained earnings and cash flows for the fiscal year-to-date period then ended, prepared by the Fund in accordance in all material respects with generally accepted accounting principles (“GAAP”), except as otherwise stated therein (and subject to the absence of footnotes and ordinary year-end adjustments), and certified to by its chief financial officer or such other officer reasonably acceptable to the Lender; and (c) promptly after the same are made available to the Fund’s Members, and in any event within one hundred twenty (120) days after the close of each fiscal year of the Fund, a copy of the Fund’s balance sheet as of the last day of the fiscal year then ended and its statements of income, retained earnings and cash flows for the fiscal year then ended, and accompanying notes thereto, accompanied by an unqualified opinion (as to scope of audit or going concern) thereon of a firm of independent public accountants of recognized standing, selected by the Fund and reasonably satisfactory to the Lender to the effect that the financial statements present fairly in all material respects in accordance with GAAP the financial condition of the Fund as of the close of such fiscal year and the results of operations and cash flows for the fiscal year then ended. Notwithstanding anything to the contrary contained herein, no financial statements or other financial deliveries shall be required to be furnished to the Lender pursuant to clauses (b) and (c) of this Section until such time as such financial statements or deliveries are first made available to the Fund’s Members. 7. Covenants. In consideration of establishing and maintaining the Loan Account, the Fund covenants and agrees: (a) to provide the Lender with notice promptly after any senior officer of the Fund or the Adviser becoming aware of (i) any event which would give any one or more of the Fund’s Members the right to terminate or suspend its Capital Commitment, whether in whole or in part, and whether or not contingent upon the passage of time or the giving of notice or both, (ii) a Key Person Event or an Alternative Key Person Event, (iii) any action taken, or to be taken, which could reasonably be expected to result in the termination of the Investment Period, (iv) any event which would permit a Member to withdraw from the Fund, (v) any event or agreement which would excuse a Member from participating in any capital call relating to the Fund, (vi) any assignment of a Member’s membership interest in the Fund, (vii) either the Fund or New Mountain -6- Finance Advisers BDC, L.L.C., a Delaware limited liability company, and the investment manager of the Fund (the “Adviser”), being a named party in any material litigation, arbitration or other judicial or administrative proceeding, (viii) receipt of a notice of default under an SPV Facility (as defined herein) and (ix) of the occurrence of any repurchase obligation by the Fund under an SPV Facility (including any repurchase obligation for ineligible assets) or any demand for payment under a so-called “bad-boy” or “limited recourse” guaranty with respect to an SPV Facility; (b) unless otherwise agreed to by the Lender in writing, that promptly after the transfer of assets by the Fund into a special purpose vehicle for financing by any other financial institution (each, an “SPV Facility”), the Fund shall apply the cash proceeds (net of financing expenses and, unless a Default (as defined above) then exists and is continuing, other current expenses of the Fund, including current management fees then due) from such financing to the repayment of the then outstanding principal balance of the Loans and accrued and unpaid interest thereon until paid in full; (c) that the aggregate amount of outstanding indebtedness of the Fund does not as of the date hereof and will not at any time hereafter exceed the 5070% (the “Advance Rate”) of the Fund’s Remaining Capital Commitments (the “Advance RateMaximum Permitted Indebtedness”); provided, however, that such availability is subject to change solely at the Lender’s discretion upon notice to the Fund, and in the event such change requires a repayment of the Loans or a portion thereof.

If the Lender pays any amount in respect of any such Indemnified Taxes, the Fund shall reimburse the Lender for that payment within thirty (30) days of the written demand by the Lender; provided, that the Lender shall have delivered to the Fund official tax receipts evidencing that payment or certified copies thereof (or other evidence reasonably satisfactory to the Fund).
