ITEM 1.01 Entry into a Material Definitive Agreement

As previously announced on June 12, 2014, Oaktree Capital Management, L.P. (the “Issuer”), and Oaktree Capital I, L.P., Oaktree Capital II, L.P. and Oaktree AIF Investments, L.P. (the “Guarantors” and together with the Issuer, the “Obligors”) entered into a note and guarantee agreement (the “Note Agreement”) with certain accredited investors (collectively, the “Investors”) on July 11, 2014, pursuant to which the Issuer agreed to issue and sell to the Investors $50 million aggregate principal amount of its 3.91% Senior Notes, Series A, due September 3, 2024 (the “Series A Notes”), $100 million aggregate principal amount of its 4.01% Senior Notes, Series B, due September 3, 2026 (the “Series B Notes”) and $100 million aggregate principal amount of its 4.21% Senior Notes, Series C, due September 3, 2029 (the “Series C Notes” and together with the Series A Notes and the Series B Notes, the “Notes”). The Notes will be senior unsecured obligations of the Issuer, guaranteed (the “Guarantees”) by the Guarantors on a joint and several basis. Closing is expected to occur on September 3, 2014. The offer and sale of the Notes and the Guarantees were and will be made solely in private placement transactions exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended.

The Series A Notes, the Series B Notes and the Series C Notes will bear interest at a rate of 3.91% per annum, 4.01% per annum and 4.21% per annum, respectively, in each case, payable semi-annually, and will be due on September 3, 2024, September 3, 2026 and September 3, 2029, respectively. The Note Agreement provides for certain affirmative and negative covenants, including financial covenants relating to the Obligors’ combined leverage ratio and minimum assets under management. In addition, the Notes Agreement contains customary representations and warranties of the Obligors and customary events of default, in certain cases, subject to cure periods. The Issuer may prepay all, or from time to time any part of, the Notes at any time, subject to the Issuer’s payment of the applicable make-whole amount determined with respect to such principal amount prepaid. Upon the occurrence of a change of control, the Issuer will be required to make an offer to prepay the Notes together with the applicable make-whole amount determined with respect to such principal amount prepaid. The Note Agreement contains customary events of default, including, among other things, failure to pay interest, breach of certain covenants, failure to pay certain other indebtedness at maturity or upon earlier acceleration, and certain events of insolvency or bankruptcy. Upon the occurrence and continuance of an event of default, the holders of at least a majority in outstanding principal amount of the Notes may declare the Notes immediately due and payable by providing notice to the Issuer and exercise other rights and remedies. Such termination and declaration will occur automatically in the event of certain insolvency or bankruptcy related events of default.

The Issuer intends to use the proceeds from the sale of the Notes for working capital and general corporate purposes of the Obligors and their respective subsidiaries.

The above description of the terms and conditions of the Notes and the Note Agreement does not purport to be complete and is qualified in its entirety by the full text of the Note Agreement and the forms of the Notes, attached as Exhibits 4.1, 4.2, 4.3 and 4.4, respectively, to this Form 8-K and incorporated herein by reference.
