provided to investors by, or with the approval of, SBA Finance, in connection with the marketing of the offering and sale of the Offered Securities listed on Schedule III, including the sales presentation dated October 4, 2021 (the
“Sales Slides”) (collectively, the “Marketing Materials”) or (C) any Form ABS-15G furnished to the SEC on EDGAR with respect to the Offered Securities, (ii) the
omission or alleged omission to state in the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or in any Marketing Materials or in any Form ABS-15G furnished to
the SEC on EDGAR with respect to the Offered Securities, any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading,
(iii) the website maintained in compliance with Rule 17g-5 under the Exchange Act by or on behalf of SBA Finance, the Borrowers, the Guarantor or SBA Holdings in connection with the offering of the
Offered Securities, or (iv) any act or failure to act or any alleged act or failure to act by such Initial Purchaser in connection with, or relating in any manner to, the Offered Securities or the offering contemplated hereby, and which is
included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clauses (i), (ii) or (iii) above (provided that SBA Finance shall not be liable under clause (iv) to
the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Initial
Purchaser through its gross negligence or willful misconduct); and shall reimburse such Initial Purchaser and each such director, officer, employee, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably
incurred by such Initial Purchaser, director, officer, employee, affiliate or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that SBA Finance shall not be liable 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 the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or in any Marketing Materials in reliance upon and in conformity with (i) the Initial Purchasers’
Information or (ii) the information set forth in the Preliminary Offering Memorandum and the Offering Memorandum under the heading “Description of the Trust Agreement—The Servicer” (the “Servicer Information”).
The foregoing indemnity agreement is in addition to any liability which SBA Finance may otherwise have to such Initial Purchaser or to any director, officer, employee, affiliate or controlling person of such Initial Purchaser. 

  
 36 












 (b) Each of the Initial Purchasers, severally and not jointly, shall indemnify and hold
harmless SBA Finance, its directors, officers, employees and affiliates, and each person, if any, who controls SBA Finance within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof, to which SBA Finance or any such director, officer, employee, affiliate or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or (B) the Marketing
Materials or (ii) the omission or alleged omission to state in the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or in any Marketing Materials, any material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with the Initial Purchasers’ Information, and shall reimburse SBA Finance and any such director, officer, employee, affiliate or controlling person for any legal or other expenses reasonably
incurred by SBA Finance or any such director, officer, employee, affiliate or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are
incurred. The foregoing indemnity agreement is in addition to any liability which the Initial Purchasers may otherwise have to SBA Finance or any such director, officer, employee, affiliate or controlling person. 

(c) Promptly after receipt by an indemnified party under this Section 7 of the 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 the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure
to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other indemnifying party, to assume the defense thereof with counsel reasonably satisfactory
to the indemnified party (which may be counsel to an indemnifying party with the consent of the indemnified party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the
indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of
investigation; provided, however, that the Initial Purchasers shall have the right to employ counsel (in addition to local counsel, if necessary) to represent jointly the Initial Purchasers and their respective directors, officers, employees,
affiliates and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Initial Purchasers against SBA Finance under this Section 7 if (i) the indemnifying party has
agreed in writing to pay such fees and expenses, (ii) the indemnifying party has 

  
 37 












 
failed to provide counsel reasonably satisfactory to the Initial Purchasers in a timely manner, (iii) the Initial Purchasers shall have reasonably concluded that there may be legal defenses
available to them that are different from or in addition to those available to the indemnifying parties or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying parties and the Initial
Purchasers and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in that event the fees and expenses of such separate counsel shall be paid by SBA Finance. No
indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or
consent includes (x) an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the
indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or
judgment. 
 (d) If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold
harmless an indemnified party under Section 7(a) or 7(b) 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 SBA Finance and its affiliates on the one hand and the Initial Purchasers on the other from the offering of the Offered Securities 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 SBA Finance and its affiliates on the one hand and the Initial Purchasers on the other with respect to
the statements or omissions which 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 SBA Finance and its affiliates on the one
hand and the Initial Purchasers on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Offered Securities purchased under this Agreement (before deducting expenses)
received by SBA Finance and its affiliates, on the one hand, and the total discounts and commissions received by the Initial Purchasers with respect to the Offered Securities purchased under this Agreement, on the other hand, bear to the total gross
proceeds from the offering of the Offered Securities under this Agreement. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to


  
 38 












 
state a material fact relates to information supplied by SBA Finance or its affiliates, or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information
and opportunity to correct or prevent such statement or omission. SBA Finance and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation
(even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which 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 Section shall be deemed to include, for purposes of this Section 7(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 Section 7(d), the Initial Purchasers shall not be required to contribute any amount in excess of the amount by which the total
price at which the Offered Securities purchased by them were resold to Eligible Purchasers exceeds the amount of any damages which the Initial Purchasers have otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement
or omission or alleged omission. 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. The Initial Purchasers’ obligations to contribute as provided in this Section 7(d) are several in proportion to their respective obligations and not joint. 

(e) The Initial Purchasers confirm and SBA Finance acknowledges that, for all purposes of this Agreement, the information relating to the
Initial Purchasers furnished to SBA Finance by or on behalf of the Initial Purchasers expressly for use in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum (the “Initial
Purchasers’ Information”) consists solely of (i) the second sentence of the last paragraph on the cover page of the Preliminary Offering Memorandum and the Offering Memorandum, the second paragraph of the section of
the Preliminary Offering Memorandum and the Offering Memorandum entitled “Offering of Securities” and (ii) the names, addresses and telephone numbers on page 33 of the Sales Slides. 

8. Persons Entitled to Benefit of Agreement. 

This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, the Trustee, SBA Finance and their respective
successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except as provided in Section 7 with respect to officers, directors, employees, affiliates or controlling persons of SBA Finance and
the Initial Purchasers and in Section 4(e) with respect to holders and prospective purchasers of the Offered Securities. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this
Section 8, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. 

  
 39 












 9. Expenses.

related fees and expenses of any counsel to such parties); (x) the fees and expenses of counsel to SBA Finance and the Transaction Parties, (xi) the fees and expenses of the Servicer (including related fees and expenses of counsel to the
Servicer); (xii) the reasonable fees and disbursements of Simpson Thacher & Bartlett LLP, counsel to the Initial Purchasers; (xiii) the reasonable
out-of-pocket expenses of the Initial Purchasers incurred by the Initial Purchasers in connection with this Agreement and the purchase and reoffering of the Offered
Securities, including, without limitation, all travel expenses of the Initial Purchasers and all expenses of the Initial Purchasers incurred in connection with attending or hosting meetings with prospective purchasers of the Offered Securities;
(xiv) the reasonable out-of-pocket fees and expenses incurred by SBA Finance in connection with attending meetings with prospective purchasers of the Offered
Securities, (xv) all expenses and application fees incurred in connection with the approval of the Offered Securities for book entry transfer by DTC; and (xvi) all other costs and expenses incident to the performance of the obligations of
SBA Finance under this Agreement which are not otherwise specifically provided for in this Section 9. 
 (b) In addition, if the Trustee
shall fail to tender the Offered Securities for delivery to the Initial Purchasers by reason of any failure, refusal or inability on the part of the Trustee or SBA Finance to perform any agreement on its part to be performed, or if the Initial
Purchasers shall decline to purchase the Offered Securities because any other condition of the Initial Purchasers’ obligations hereunder required to be fulfilled is not fulfilled, SBA Finance will reimburse the Initial Purchasers for any
reasonable out-of-pocket fees and expenses incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase of the Offered Securities,
including the reasonable fees and disbursements of Simpson Thacher & Bartlett LLP, counsel to the Initial Purchasers, and the reasonable out-of-pocket fees and
expenses incurred by the Initial Purchasers in connection with hosting or attending meetings with prospective purchasers of the Offered Securities.

arising out of, or incurred in connection with, this Agreement, the marketing and Offering of the Offered Securities hereunder, or any act or omission of the Trustee relating to the exercise and performance of any of the rights and duties of the
Trustee hereunder; provided, however, that the Trustee shall not be entitled to indemnification pursuant to this Section 10 for any loss, liability, claim or expense incurred by reason of any willful misfeasance, bad faith or gross negligence
of the Trustee in the performance of, or reckless disregard of, its obligations and duties hereunder.

may have to SBA Finance shall be limited to those duties and obligations specifically stated herein; and (iv) the Initial Purchasers and their respective affiliates may have interests that differ from those of SBA Finance. SBA Finance hereby
waives any claims that SBA Finance may have against the Initial Purchasers with respect to any breach of fiduciary duty in connection with the offering of the Offered Securities.

	2 	 The Initial Purchasers expect to deliver the Offered Securities on October 27, 2021, which will be the twelfth
(12th) Business Day following the date of pricing of the Offered Securities (such settlement schedule being herein referred to as “T+12”). Under Rule 15c6-1 under the United States Securities
Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in two Business Days, unless the parties to any such trade expressly agree otherwise. Because the Offered Securities
will not be delivered before closing, purchasers trading the Offered Securities on the date of pricing or the next nine Business Days will be required to specify a longer settlement cycle at the time of any such trade to prevent a failed settlement.
Purchasers of the Offered Securities who wish to trade Offered Securities on the date of pricing or the next nine Business Days should consult their own advisor.

“Prepayment Consideration” means with respect to the prepayment of a Component of the Mortgage Loan (or portion thereof) corresponding to a
Series of the Offered Securities or any Component of the Mortgage Loan (or portion thereof) corresponding to a Subclass of the Existing Securities, an amount equal to the excess, if any, of (i) the present value as of the date of prepayment (by
acceleration or otherwise) of all future installments of principal and interest that the Borrowers would otherwise be required to pay on such Component (or portion thereof) on the related Due Date from the date of such prepayment to and including
the first Due Date that occurs less than (a) eighteen months, in the case of the 2021-3C Component, the 2020-2C Component or the
2014-2C Component or (b) twelve months, in the case of the 2021-2C Component, the 2021-1C Component, the 2020-1C Component, the 2019-1C Component or the 2018-1C Component, in each case, prior to the Anticipated Repayment Date with respect
to such Component, absent such prepayment, assuming the entire Component Principal Balance of such Component is required to be paid on such Due Date, with such present value determined by the use of a discount rate equal to the sum of (x) the
yield to maturity (adjusted to a “mortgage equivalent basis” pursuant to the standards and practices of the Securities Industry Association), on the Due Date relating to the date of such prepayment, of the United States Treasury Security
having the maturity closest to the Distribution Date that occurs eighteen or twelve months, as applicable, prior to the Assumed Final Distribution Date related to the Anticipated Repayment Date for such Component plus (y)(A) with respect to the 2021-2C Component, 0.20% or (B) with respect to each other Component, 0.50% over (ii) the Component Principal Balance of such Component (or portion thereof) on the date of such

 The Prepayment Consideration payable with respect to the
prepayment of the Component of the Mortgage Loan (or portion thereof) corresponding to either Series of the Offered Securities or any Component of the Mortgage Loan (or portion thereof) corresponding to a Subclass of the Existing Securities will
equal the excess, if any, of (i) the present value as of the date of prepayment (by acceleration or otherwise) of all future installments of principal and interest that the Borrowers would otherwise be required to pay on such Component (or
portion thereof) on the related Due Date from the date of such prepayment to and including the first Due Date that occurs less than (a) eighteen months, in the case of the 2021-3C Component, the 2020-2C Component or the 2014-2C Component or (b) twelve months, in the case of the 2021-2C Component, the 2021-1C Component, the 2020-1C Component, the 2019-1C Component or the 2018-1C Component, in
each case, prior to the Anticipated Repayment Date with respect to such Component, absent such prepayment, assuming the entire Component Principal Balance of such Component is required to be paid on such Due Date, with such present value determined
by the use of a discount rate equal to the sum of (x) the yield to maturity (adjusted to a “mortgage equivalent basis” pursuant to the standards and practices of the Securities Industry Association), on the Due Date relating to the
date of such prepayment, of the United States Treasury Security having the maturity closest to the Distribution Date that occurs eighteen or twelve months, as applicable, prior to the Assumed Final Distribution Date related to the Anticipated
Repayment Date for such Component plus (y)(A) with respect to the Series 2021-2C Component, 0.20% or (B) with respect to each other Component, 0.50% over (ii) the Component
Principal Balance of such Component (or portion thereof) on the date of such prepayment. Prepayment Consideration will not be payable in respect of the 2021-3R Component or any other Component of the Mortgage
Loan corresponding to any other Series of Risk Retention Securities.
