Oaktree Specialty Lending Corporation expects that delivery of the Notes will be made against payment therefor on or about May 18, 2021, which will be the fifth business day following the date of the pricing of the Notes (such settlement being herein referred to as “T+5”). Under Rule 15c6-1 promulgated under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the second business day prior to the date of delivery hereunder will be required, by virtue of the fact that the Notes initially will settle in T+5 business days, to specify an alternative settlement arrangement at the time of any such trade to prevent a failed settlement.
