Form of Notice to Dyal Capital Partners [•] Investors and Associated Co-Investors

February 15, 2021

To our Dyal Capital Partners [•] Investors and Associated Co-Investors,

We are writing to update you regarding the pending Blue Owl strategic combination. We continue to work toward our expected closing in the first half of this year (subject to the satisfaction of customary closing conditions). You should expect to see formal consent documents in the coming days relating to the Blue Owl transaction; as always, please reach out if you have any questions once you have had a chance to review them.

We are very appreciative of the support we have received from numerous investors, Partner Managers and other key stakeholders. We are, however, disappointed to share that Sixth Street, one of ten Partner Managers in Dyal Capital Partners III (collectively, with its various associated investment vehicles, “Fund III”), has brought a lawsuit against Fund III and Neuberger Berman Group LLC seeking, among other things, an injunction against the Blue Owl transaction, in what we believe is a misguided effort based on contractual rights that, in our view, they do not possess.

We do not believe that Sixth Street’s suit has any merit, and we are working with leading counsel to defend against the suit vigorously.

We continue to believe that the merits of the Blue Owl strategic combination are powerful: access to a broader range of compelling investment opportunities for our investors and a more comprehensive suite of capital solutions for our Partner Managers. As we have stated previously, very little is expected to change in the way Dyal conducts its business when we become Blue Owl. The Dyal investment team will remain the same, and the way we work with our Partner Managers will be consistent with both our past practice and best practices across the industry.

We should also add that the Dyal platform is continuing to operate business-as-usual as we work to close the Blue Owl combination. The investment pipeline for our actively investing funds is robust, with multiple transactions closed in Dyal Capital Partners IV and V since the Blue Owl news became public.

Thank you for your continued partnership. We are always available to speak with you, so please reach out if you have any questions.




Michael Rees

Head of Dyal Capital Partners
