which case no consent of the Borrowers is required), which shall not be unreasonably withheld or delayed, may sell, assign or transfer all or any part of its rights and obligations under or relating to Revolving Advances and/or Term Loans under this
Agreement and the Other Documents to one or more additional banks or financial institutions and one or more additional banks or financial institutions may commit to make Advances hereunder (each a “Purchasing Lender”) in minimum

effectuate the foregoing.

other entity that (i) is engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its business and (ii) is administered, serviced or managed by the assigning

Transfer Supplement modified as appropriate to reflect the interest being assigned (“Modified Commitment Transfer Supplement”), executed by any intermediate purchaser, the Purchasing CLO, the transferor Lender, and Agent as
appropriate and delivered to Agent for recording.
