that such liabilities will be computed at the amount that, in the light of all the facts and circumstances existing at such time,
represents the amount that can reasonably be expected to become an actual or matured liability.

Certain Agreements of the Issuer.


 


The Issuer covenants
and agrees with the Initial Purchaser as follows:


 


(a)              
If, at any time prior to the earlier of the completion of the distribution and the 90th day following the Closing Date,
any event involving the Issuer or, to the knowledge of a Responsible Officer, the Collateral Manager shall occur as a result of
which the Final Memorandum (as then amended or supplemented) would include an untrue statement of a material fact or omit to state
any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading,
the Issuer will immediately notify the Initial Purchaser and will prepare and furnish to the Initial Purchaser an amendment or
supplement to the Final Memorandum that will correct such statement or omission. The Issuer will not at any time amend or supplement
the Final Memorandum (i) prior to having furnished the Initial Purchaser with a copy of the proposed form of the amendment
or supplement and giving the Initial Purchaser a reasonable opportunity to review the same or (ii) except to the extent the
Issuer may determine that the Issuer is required to so disclose pursuant to applicable law and after consultation with the Initial
Purchaser (and, in such a circumstance, shall remove all references to the Initial Purchaser therefrom if so requested by the Initial
Purchaser), in a manner to which the Initial Purchaser or its counsel shall object.


 


(b)              
During the period referred to in Section 6(a), the Issuer will furnish to the Initial Purchaser, without charge,
copies of the Final Memorandum (including all exhibits and documents incorporated by reference therein), the Transaction Documents,

Initial Purchaser may from time to time reasonably request.


 


(c)              
Subject to compliance with Regulation FD, at all times during the course of the private placement contemplated hereby
and prior to the Closing Date, (i) the Issuer will make available to each offeree (x) the Additional Offering Documents and
(y) such information concerning any other relevant matters as it or any of its affiliates possess or can acquire without unreasonable
effort or expense, as determined in good faith by it or such affiliate, as applicable, (ii) the Issuer will provide each offeree
the opportunity to ask questions of, and receive answers from, it concerning the terms and conditions of the offering and to obtain
any additional information, to the extent it or any of its affiliates possess such information or can acquire it without unreasonable
effort or expense (as determined in good faith by it or such affiliate, as applicable), necessary to verify the accuracy of the
information furnished to the offeree, (iii)  the Issuer will not publish or disseminate any material in connection with the
offering of the Notes except as contemplated herein or as consented to by the Initial Purchaser, (iv) the Issuer will advise
the Initial Purchaser promptly of the receipt by the Issuer of any communication from the SEC or any state securities authority
concerning the offering or sale of the Notes, (v) the Issuer will advise the Initial Purchaser promptly of the commencement
of any lawsuit or proceeding to which the Issuer is a party relating to the offering or sale of the Notes, and (vi) the Issuer

the Securities Act (i) to such Noteholder or beneficial owner, (ii) to a prospective purchaser of such Note or interest
therein designated by such Noteholder or beneficial owner, or (iii) to the Trustee for delivery to such Noteholder, beneficial
owner or prospective purchaser, in order to permit compliance by such Noteholder or beneficial owner with Rule 144A under
the Securities Act in connection with the resale of such Note or beneficial interest therein by such holder or beneficial owner
in reliance on Rule 144A under the Securities Act unless, at the time of such request, the Issuer is subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act or is exempt from such reporting requirements pursuant to and
in compliance with Rule 12g3-2(b) of the Exchange Act.

[Reserved].


 


(g)              
Neither the Issuer nor any of its affiliates or any other Person acting on their behalf shall engage, in connection with
the offer and sale of the Notes, in any form of general solicitation or general advertising within the meaning of Rule 502(c)
of Regulation D under the Securities Act, including, but not limited to, the following:

the Initial Purchaser and the Final Memorandum in connection with the offer or sale of the Notes as contemplated by this Agreement,
unless the Initial Purchaser shall have consented to the use thereof; if the Issuer or any of its affiliates makes any press release
including "tombstone" announcements, in connection with the Transaction Documents, the Issuer shall permit the Initial
Purchaser to review and approve such release in advance.


 


(i)                
The Issuer shall not take, or permit or cause any of its affiliates to take, any action whatsoever which would have the
effect of requiring the registration, under the Securities Act, of the offer or sale of the Notes.


 


(j)                
The Issuer shall not take, directly or indirectly, any action designed to or which has constituted or which might reasonably

any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made, not misleading.

Section 8.              
Indemnification and Contribution.


 


(a)              
The Issuer (an "indemnifying party" as such term is used in this Agreement), shall indemnify and hold harmless
the Initial Purchaser, its officers, directors, employees, agents and each person, if any, who controls the Initial Purchaser within
the meaning of either the Securities Act or the Exchange Act and the affiliates of the Initial Purchaser (each an "indemnified
party" as such term is used in this Agreement) from and against any loss, claim, damage or liability, joint or several,
and any action in respect thereof, to which any indemnified party may become subject, under the Securities Act or Exchange Act
or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or
alleged untrue statement of a material fact contained in any Memorandum or any Additional Offering Document or arises out of, or
is based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein in light of the circumstances under which they were made not misleading, and shall reimburse any such
indemnified party for any legal and other expenses reasonably incurred by such indemnified party in investigating or defending
or preparing to defend against any such loss, claim, damage, liability or action; provided, however,
that the indemnifying parties shall not be liable to any such indemnified party in any such case to the extent that any such loss,
claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission
or alleged omission made in any Memorandum or any Additional Offering Document written information relating to such indemnified
party and furnished to the Collateral Manager by such indemnified party specifically for inclusion therein; provided,
further, that the foregoing indemnity shall not inure to the benefit of any indemnified party from whom the person
asserting any such loss, claim, damage or liability purchased the Purchased Notes which are the subject thereof if the indemnified
party sold Purchased Notes to the person alleging such loss, claim, damage or liability without sending or giving a copy of the
Final Memorandum at or prior to the confirmation of the sale of the Purchased Notes, if the Collateral Manager shall have previously
furnished copies thereof to such indemnified party and the loss, claim, damage or liability of such person results from an untrue
statement or omission of a material fact contained in the Initial Preliminary Memorandum or the Second Preliminary Memorandum which
was corrected in the Final Memorandum. The foregoing indemnity is in addition to any liability that the indemnifying parties may
otherwise have to any indemnified party. The indemnifying parties acknowledge that the statements set forth in the Final Memorandum
(x) under the caption: "Plan of Distribution" (but solely the second, fourth, seventh, ninth, eleventh, twelfth
and thirteenth paragraphs under such caption) of the Final Memorandum, (y) relating to Wells Fargo Securities, LLC on page
i of the Final Memorandum in the ninth, tenth and eleventh paragraphs under the heading "Important Information Regarding This
Offering Circular and the Secured Debt" and (z) under the caption "Risk Factors—Relating to Certain Conflicts
of Interest—The Issuer will be subject to various conflicts of interest involving Wells Fargo Securities and its Affiliates"
constitute the only written information furnished to the Collateral Manager by or on behalf of the indemnified parties specifically
for inclusion in any Memorandum or any Additional Offering Document.


 






     14


     


    

 





(b)              
Golub Capital BDC, Inc. (the "Company")
(an "indemnifying party" as such term is used in this Agreement, solely for purposes of the indemnity provided
under this clause (b)), shall indemnify and hold harmless each indemnified party from and against any loss, claim, damage or liability,
joint or several, and any action in respect thereof, to which any indemnified party may become subject, under the Securities Act
or Exchange Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any material
breach by the Company of its representations, covenants or obligations under the E.U. Risk Retention Letter and shall reimburse
any such indemnified party for any legal and other expenses reasonably incurred by such indemnified party in investigating or defending
or preparing to defend against any such loss, claim, damage, liability or action. The foregoing indemnity is in addition to any
liability that the indemnifying parties may otherwise have to any indemnified party.


 


(c)              
Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement
of any action, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this
Section 8, notify such indemnifying party in writing of the claim or commencement of that action; provided,
however, that the failure to notify an indemnifying party shall not relieve such indemnifying party from any liability
that it may have to an indemnified party under this Section 8, except to the extent that such indemnifying party has
been prejudiced by such failure; and, provided, further, that the failure to notify an indemnifying
party shall not relieve such indemnifying party from any liability that it may have to an indemnified party otherwise than under
this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify an indemnifying
party thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified
party. After notice from any such indemnifying party or parties to the indemnified party or parties of its or their election to
assume the defense of such claim or action, any such indemnifying party or parties shall not be liable to the indemnified party
under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party or parties in connection
with the defense thereof; provided that the indemnified party seeking such indemnity shall have the right to employ
counsel to represent it and any other indemnified party who may be subject to liability arising out of any claim or action in respect
of which indemnity may be sought by an indemnified party against an indemnifying party under this Section 8, if (i) in
the reasonable judgment of such indemnified party, there may be legal defenses available to it and any other indemnified party
different from or in addition to those available to the Company or the Issuer, as applicable, or there is a conflict of interest
between it and any other indemnified party, on one hand, and the Company or the Issuer, as applicable, on the other hand, or (ii) 
the Company or the Issuer, as applicable, shall fail to select counsel reasonably satisfactory to such indemnified party or parties,
and in such event the fees and expenses of such separate counsel shall be paid by the Company or the Issuer, as applicable. In
no event shall the Company or the Issuer, as applicable, be liable for the fees and expenses of more than one separate firm of
attorneys for all indemnified parties in connection with any other action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified
party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement
(i) does not include a statement as to, or admission of, fault, culpability or a failure to act by or on behalf of any such
indemnified party, and (ii) includes an unconditional release of such indemnified party from all liability on claims that
are the subject matter of such proceeding.


 






     15


     


    

 


(d)              
If the indemnification provided for in this Section 8 shall for any reason be unavailable to an indemnified
party under subsection 8(a) or (b) hereof in respect of any loss, claim, damage or liability, or any action in respect
thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to
the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Issuer or the Company,
as applicable, on the one hand, and the Initial Purchaser on the other hand from the offering and sale of the Notes or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer
or the Company, as applicable, on the one hand and the Initial Purchaser on the other hand with respect to the statements, omissions
(or, in the case of the Company, breach) that resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations. The relative benefits received by the Issuer or the Company, as applicable,
on the one hand and the Initial Purchaser on the other hand with respect to such offering shall be deemed to be in the same proportion
as the total net proceeds from the offering and sale of the Notes (after deducting expenses) received by the Issuer bear to the
total fees actually received by the Initial Purchaser with respect to such offering and sale. The relative fault as between the
Initial Purchaser and the Issuer shall be determined by reference to whether the untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to information supplied by the Issuer or by the Initial Purchaser,
the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement
or omission. The Issuer, the Company and the Initial Purchaser agree that it would not be just and equitable if contributions pursuant
to this subsection 8(d) were to be determined by pro rata allocation or by any other method of allocation that does
not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this subsection 8(d)
shall be deemed to include, for purposes of this subsection 8(d), any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of
this subsection 8(d), the Initial Purchaser shall not be required to contribute any amount in excess of the aggregate
fee actually paid to the Initial Purchaser with respect to the offering of the Offered Notes. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.


 


For purposes of this
subsection (d), the term "as applicable" shall not be deemed to refer to the relative benefits or fault of the
Company except to the extent that a contribution is required solely in respect of an indemnification obligation of the Company
under subsection (b) and, in any case, the relative benefits or fault of the Company and the Issuer shall not be deemed
to be cumulative.


 


(e)              
The indemnity agreements contained in this Section 8 shall survive the delivery of the Notes, and the provisions
of this Section 8 shall remain in full force and effect, regardless of any termination or cancellation of this Agreement
or any investigation made by or on behalf of any indemnified party.


 


Section 9.              
Termination.


 


This Agreement shall
be subject to termination in the absolute discretion of the Initial Purchaser, by notice given to the Issuer prior to delivery
of and payment for the Purchased Notes, if prior to such time (i) trading in securities generally on the New York Stock Exchange
shall have been suspended or materially limited or any setting of minimum prices for trading on such exchange shall have occurred,
(ii) there shall have been, since the date hereof or the respective dates as of which information is given in the Final Memorandum,
any material adverse change in the condition, financial or otherwise, or in the properties (including, without limitation, the
Collateral Obligations) or the earnings, business affairs or business prospects of the Issuer or the Collateral Manager, whether
or not arising in the ordinary course of business, (iii) a general moratorium on commercial banking activities in New York
shall have been declared by either U.S. federal or New York State authorities, or (iv) there shall have occurred any
material outbreak or escalation of hostilities or other calamity or crises the effect of which on the financial markets of the
United States is such as to make it, in the reasonable judgment of the Initial Purchaser, impracticable or inadvisable to market
the Purchased Notes on the terms and in the manner contemplated by each Memorandum as amended or supplemented.


 


Section 10.          
Severability Clause.


 


Any part, provision,
representation, or warranty of this Agreement which is prohibited or is held to be void or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof.

The Issuer agrees with
the Initial Purchaser at the date of this Agreement and on the Closing Date as follows:


 


(i)                
In the event a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of this
Agreement (and any interest and obligation in or under, and any property securing, this Agreement) from such Covered Party will

or a State of the United States.


 


(ii)             
In the event that a Covered Party or any BHC Affiliate of such Covered Party becomes subject to a proceeding under a U.S.
Special Resolution Regime, any Default Right under this Agreement that may be exercised against such Covered Party is permitted
