Organization	1. ORGANIZATION Goldman Sachs Private Middle Market Credit II LLC (the “Company”, which term refers to either Goldman Sachs Private Middle Market Credit II LLC or Goldman Sachs Private Middle Market Credit II LLC, together with its consolidated subsidiaries, as the context may require) was formed on December 20, 2018 as a Delaware limited liability company and commenced operations on April 11, 2019. The Company has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “Investment Company Act”). In addition, the Company has elected to be treated as a regulated investment company (“RIC”), and the Company expects to qualify annually for tax treatment as a RIC, under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its taxable year ended December 31, 2019. The Company’s investment objective is to generate current income and, to a lesser extent, capital appreciation primarily through direct originations of secured debt, including first lien debt, unitranche debt, including last-out portions of such loans, and second lien debt, and unsecured debt, including mezzanine debt, as well as through select equity investments. Goldman Sachs Asset Management, L.P. (“GSAM”), a Delaware limited partnership and an affiliate of Goldman Sachs & Co. LLC (including its predecessors, “GS & Co.”), is the investment adviser (the "Investment Adviser") of the Company. The term “Goldman Sachs” refers to The Goldman Sachs Group, Inc. (“GS Group Inc.”), together with GS & Co., GSAM and its other subsidiaries. On March 25, 2019 (the “Initial Closing Date”), the Company began accepting subscription agreements (“Subscription Agreements”) from investors acquiring common units of the Company’s limited liability company interests (“Units”) in the Company’s private offering. Under the terms of the Subscription Agreements, investors are required to make capital contributions up to the undrawn amount of their capital commitment to purchase Units each time the Company delivers a drawdown notice. On February 26, 2020, the Company’s board of directors (the “Board of Directors” or the “Board”) approved an extension of the final date on which the Company accepted Subscription Agreements (the “Final Closing Date”) to September 26, 2020. The investment period commenced on the Initial Closing Date and will continue until the third anniversary of the Final Closing Date in the Company’s private offering, provided that it may be extended by the Board of Directors, in its discretion, for one additional twelve-month period, and, with the approval of a majority-in-interest of the unitholders of the Company (the “Unitholders”), for up to one additional year thereafter. In addition, the Board of Directors may terminate the investment period at any time in its discretion. On August 2, 2023, the Board approved and authorized an extension of the investment period of the Company for an additional twelve-month period, which ended on September 26, 2024. Following the end of the investment period, the Company will have the right to issue drawdowns only (i) to pay, and/or establish reserves for, actual or anticipated Company expenses, liabilities, including the payment or repayment of indebtedness for borrowed money (including through the issuance of notes and other evidence of indebtedness), other indebtedness, financings or extensions of credit, or other obligations, contingent or otherwise, including the Management Fee (as defined below), whether incurred before or after the end of the investment period, (ii) to fulfill investment commitments made or approved by the investment committee of the Goldman Sachs Asset Management Private Credit Team prior to the expiration of the investment period, (iii) to engage in hedging transactions or (iv) to make additional investments in existing portfolio companies (including transactions to hedge interest rate or currency risks related to such additional investment). The term of the Company will expire on the five-year anniversary of the expiration of the investment period, subject to the Board of Directors’ right to liquidate the Company at any time and to extend the term of the Company for up to two successive one-year periods. Upon the request of the Board of Directors and the approval of a majority-in-interest of the Unitholders, the term of the Company may be further extended. Credit Alternatives GP LLC (the “Initial Member”), an affiliate of the Investment Adviser, made a capital contribution to the Company of one hundred dollars on April 11, 2019 and served as the sole initial member of the Company. The Company cancelled the Initial Member’s interest in the Company on May 3, 2019, the first date on which investors (other than the Initial Member) made their initial capital contribution to purchase Units.
