Ladies and Gentlemen:


 


We refer to the Senior Secured Revolving Credit Agreement
dated as of February 11, 2021 (as amended, modified or supplemented from time to time, the “Credit Agreement”; the
terms defined therein being used herein as therein defined) among Golub Capital BDC, Inc. (the “Borrower”), the Lenders
party thereto and JPMorgan Chase Bank, N.A., as Administrative Agent for said Lenders. You have advised us that the Borrower has
requested in a letter dated October 12, 2021 (the “Increase Request”) from the Borrower to the Administrative Agent
that the aggregate amount of the Commitments be increased on the terms and subject to the conditions set forth herein.


 


A. Commitment Increase. Pursuant to Section 2.07(e)
of the Credit Agreement, each of (i) Signature Bank (the “Increasing Lender”), Wells Fargo Bank, National Association
(“Wells”) and Regions Bank (“Regions” and together with Wells, the “Assuming Lenders”),
hereby agrees to make Commitments in the amount set forth opposite the name of such Increasing Lender or Assuming Lender, as applicable,
listed in Schedule I hereto pursuant to the instruction of the Administrative Agent, such Commitments to be effective as of the Increase
Date (as defined in the Increase Request); provided that the Administrative Agent shall have received a duly executed officer’s
certificate from the Borrower, dated the Increase Date, in substantially the form of Exhibit I hereto. Pursuant to Section 2.07(e)(i)(C)
of the Credit Agreement, the Administrative Agent and the Issuing Bank hereby consent to the Assuming Lenders making the Commitments in
the amount specified in the Increase Request and in Schedule I hereto.


 


B. Confirmation of Assuming Lenders and Increasing
Lender. Each Assuming Lender (i) confirms that it has received a copy of the Credit Agreement and the other Loan Documents, together
with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make
its own credit analysis and decision to enter into this Commitment Increase Agreement; (ii) agrees that it will, independently and without
reliance upon the Administrative Agent or any other Lender or Agent and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement; and (iii) acknowledges
and agrees that, from and after the Increase Date, the Commitments set forth opposite the name of such Assuming Lender listed in Schedule
I hereto shall be included in its Commitment and its Commitments and be governed for all purposes by the Credit Agreement and the other
Loan Documents. The Increasing Lender agrees that from and after the Increase Date, its Commitment Increase set forth opposite the name
of the Increasing Lender listed in Schedule I hereto shall be included in its Commitment and be governed for all purposes by the Credit
Agreement and the other Loan Documents.


 


C. Counterparts. This Commitment Increase Agreement may be executed
in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which
when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page to this Commitment Increase
Agreement by telecopy or other electronic transmission shall be effective as delivery of a manually executed counterpart of this Commitment
Increase Agreement.
