Ladies and Gentlemen:

This First Supplement to Master Note Purchase Agreement (the “Supplement”) is among TCG BDC, Inc., a Maryland corporation (the “Company”), and the institutional investors named on Schedule A attached hereto (the “Additional Purchasers”).

Reference is hereby made to that certain Master Note Purchase Agreement dated as of December 30, 2019 (the “Note Purchase Agreement”) among the Company and the Purchasers listed on Purchaser Schedule thereto. All capitalized terms not otherwise defined herein shall have the same meaning as specified in the Note Purchase Agreement. Reference is further made to Section 4.15 of the Note Purchase Agreement which requires that, prior to the delivery of any Additional Notes, the Company and each Additional Purchaser shall execute and deliver a Supplement.

The Company hereby agrees with the Additional Purchaser(s) as follows:

    1.    The Company has authorized the issue and sale of $75,000,000 aggregate principal amount of its 4.50% Series 2020 Senior Notes due December 31, 2024 (the “Series 2020 Notes”). The Series 2020 Notes shall constitute an additional Series of Notes issued under Section 2.2 of the Note Purchase Agreement and, together with the Series 2019 Notes issued pursuant to the Note Purchase Agreement and each series of Additional Notes which may from time to time hereafter be issued pursuant to the provisions of Section 2.2 of the Note Purchase Agreement, are collectively referred to as the “Notes” (such term shall also include any such notes as amended, restated or otherwise modified from time to time pursuant to Section 17 of the Note Purchase Agreement and including any such notes issued in substitution therefor pursuant to Section 13 of the Note Purchase Agreement). The Series 2020 Notes shall be substantially in the form set out in Exhibit 1 hereto with such changes therefrom, if any, as may be approved by the Additional Purchaser(s) and the Company.

    2.    Subject to the terms and conditions hereof and as set forth in the Note Purchase Agreement and on the basis of the representations and warranties hereinafter set forth, the Company agrees to issue and sell to each Additional Purchaser, and each Additional Purchaser agrees to purchase from the Company, Series 2020 Notes in the principal amount set forth opposite such Additional Purchaser’s name on Schedule A hereto at a price of 100% of the principal amount thereof on the closing date hereinafter mentioned.

    3.    The sale and purchase of the Series 2020 Notes to be purchased by each Additional Purchaser shall occur at the offices of Chapman and Cutler LLP, 111 West Monroe Street, Chicago, Illinois 60603, at 8:00 a.m. Chicago time, at the closing (the “Series 2020 Closing”) on December 10, 2020 or on such other Business Day thereafter on or prior to December 11, 2020 as may be agreed upon by the Company and the Additional Purchasers. At the Series 2020 Closing, the Company will deliver to each Additional Purchaser the Series 2020 Notes to be purchased by such Additional Purchaser in the form of a single Series 2020 Note (or such greater number of Series 2020 Notes in denominations of at least $100,000 as such Additional Purchaser may request) dated the date of the Series 2020 Closing and registered in such Additional Purchaser’s name (or in the name of such Additional Purchaser’s nominee), against delivery by such Additional Purchaser to the Company or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Company as set forth in wire instructions provided by the Company. If, at the Series 2020 Closing, the Company shall fail to tender such Series 2020 Notes to any Additional Purchaser as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to any Additional Purchaser’s satisfaction, such Additional Purchaser shall, at such Additional Purchaser’s election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such Additional Purchaser may have by reason of such failure by the Company to tender such Series 2020 Notes or any of the conditions specified in Section 4 not having been fulfilled to such Additional Purchaser’s satisfaction.

    4.    The obligation of each Additional Purchaser to purchase and pay for the Series 2020 Notes to be sold to such Additional Purchaser at the Series 2020 Closing is subject to the fulfillment to such Additional Purchaser’s satisfaction, prior to the Series 2020 Closing, of the conditions set forth in Section 4 of the Note Purchase Agreement with respect to the Series 2020 Notes to be purchased at the Series 2020 Closing as if each reference to “Notes,” “Closing” and “Purchaser” set forth therein was modified to refer the “Series 2020 Notes,” the “Series 2020 Closing” and the “Additional Purchaser” (each as defined in this Supplement) and to the following additional conditions:

    (a)    Except as supplemented, amended or superseded by the representations and warranties set forth in Exhibit A hereto, each of the representations and warranties of the Company set forth in Section 5 of the Note Purchase Agreement shall be correct as of the date of the Series 2020 Closing (except for representations and warranties which apply to a specific earlier date which shall be true as of such earlier date or as of the date specified in Exhibit A to the extent such provision is superseded in Exhibit A) and the Company shall have delivered to each Additional Purchaser an Officer’s Certificate, dated the date of the Series 2020 Closing certifying that such condition has been fulfilled.

    (b)    Contemporaneously with the Series 2020 Closing, the Company shall sell to each Additional Purchaser, and each Additional Purchaser shall purchase, the Series 2020 Notes to be purchased by such Additional Purchaser at the Series 2020 Closing as specified in Schedule A.

    5.    The Adjusted Interest Rate for the Series 2020 Notes shall be 5.50% per annum.

    6.    In addition to the covenants and agreements set forth in the Note Purchase Agreement, the Company covenants and agrees, for the benefit of the Additional Purchasers and each other holder of a Note, that the following definition is hereby added to the Schedule A of Note Purchase Agreement:

“Foreign Subsidiary” means any (a) direct or indirect Subsidiary of the Company that is organized under the laws of any jurisdiction other than the United States or its territories or possessions and that is treated as a corporation for United States federal income tax purposes, (b) direct or indirect Subsidiary of the Company which is a “controlled foreign corporation” within the meaning of the Code, (c) direct or indirect Subsidiary of the Company substantially all of whose assets consist of the capital stock of one or more direct or indirect Foreign Subsidiaries or (d) a Subsidiary of a Foreign Subsidiary.

    7.    Each Additional Purchaser represents and warrants that the representations and warranties set forth in Section 6 of the Note Purchase Agreement are true and correct on the date hereof with respect to the purchase of the Series 2020 Notes by such Additional Purchaser as if each reference to “Notes,” “Closing” and “Purchaser” set forth therein was modified to refer the “Series 2020 Notes,” the “Series 2020 Closing” and the “Additional Purchaser” and each reference to “this Agreement” therein was modified to refer to the Note Purchase Agreement as supplemented by this Supplement.

    8.    The Company and each Additional Purchaser agree to be bound by and comply with the terms and provisions of the Note Purchase Agreement as fully and completely as if such Additional Purchaser were an original signatory to the Note Purchase Agreement.

The execution hereof shall constitute a contract between the Company and the Additional Purchaser(s) for the uses and purposes hereinabove set forth, and this agreement may be executed in any number of counterparts, each executed counterpart constituting an original but all together only one agreement.

    Section 5.3.    Disclosure. The Company has delivered to each Additional Purchaser a copy of a Slide Deck, dated October 2020 (the “Deck”), relating to the transactions contemplated hereby. The Deck does not contain any untrue statement of a material fact. The Company’s most recent Form 10-K and Form 10-Q fairly describe, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. This Agreement, the Deck and the documents, certificates or other writings delivered to the Additional Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby and the Exchange Act Reports (collectively, the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents, since December 31, 2019, there has been no change in the financial condition, operations, business, properties or prospects of the Company or any Subsidiary taken as a whole except changes that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company that could reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents.

    Section 5.4.    Organization and Ownership of Shares of Subsidiaries. (a) Schedule 5.4 attached hereto (which schedule amends and restates Schedule 5.4 to the Note Purchase Agreement in its entirety) contains (except as noted therein) complete and correct lists of (i) the Company’s Subsidiaries, showing, as to each such Subsidiary, the name thereof, the jurisdiction of its organization, the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary and (ii) the Company’s directors and senior officers.

    Section 5.5.    Financial Statements; Material Liabilities. All of the financial statements included in the Exchange Act Reports (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the respective dates of such financial statements and the consolidated results of their operations and cash flows for the respective periods covered thereby and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments).

    Section 5.13.    Private Offering by the Company. Neither the Company nor anyone acting on its behalf has offered the Series 2020 Notes or any similar Securities for sale to, or solicited any offer to buy the Series 2020 Notes or any similar Securities from, or otherwise approached or negotiated in respect thereof with, any Person other than the Additional Purchasers and not more than 6 other Institutional Investors, each of which has been offered the Series 2020 Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Series 2020 Notes to the registration requirements of section 5 of the Securities Act or to the registration requirements of any Securities or blue sky laws of any applicable jurisdiction.

    Section 5.14.    Use of Proceeds; Margin Regulations. The Company will apply the proceeds of the sale of the Series 2020 Notes hereunder as described in Schedule 5.14. No part of the proceeds from the sale of the Series 2020 Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any Securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 10% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 10% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

    Section 5.15.    Existing Indebtedness; Future Liens. (a) Except as described therein, Notes 6 and 7 to the Company’s most recent Form 10-Q set forth a complete and correct list of all outstanding Indebtedness of the Company and its Subsidiaries as of September 30, 2020, since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of the Company or its Subsidiaries. Neither the Company nor any Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of the Company or such Subsidiary and no event or condition exists with respect to any Indebtedness of the Company or any Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment.
