The terms of the New Advisory Agreement are identical to the terms of the Existing Advisory Agreement.

This request is a result of the recently announced Business Combination Agreement executed between Owl Rock Capital Group and Dyal Capital Partners. The definitive agreement will bring together two industry leading investment platforms focused on providing capital solutions to the alternative asset management industry. The combined business will be the surviving entity in a merger with a special purpose acquisition corporation (a “SPAC”), Altimar Acquisition Corp. (NYSE: ATAC) (the “Transaction”). The Transaction, if consummated, will result in an indirect Change in Control of the Adviser to ORCC III. This Adviser change of control will result in a termination of the current investment advisory agreement. Expected enhancements provided by the Adviser Change in Control include: • improved investment sourcing capabilities, • increased pipeline of deal opportunities, • expanded resources available to investing activity, and • enhanced ability to attract and retain talent. Your vote for this meeting is extremely important, regardless of the number of shares you own. Important Materials: Proxy Statement Shareholder Letter For holders as of January 15, 2021 Why Should I Vote? The ability to close the Transaction and deliver enhancements provided by the Adviser Change in Control is dependent on stockholder approval. The outcome of the vote can affect the value of your shares. (c) 1997-2021 Broadridge Financial Solutions Inc. P.O.
