	 	7.	Indemnification and Contribution. 

 (a) SBA Finance hereby agrees to indemnify and hold harmless each Initial Purchaser, its directors, officers and employees and each person, if any, who controls such Initial Purchaser 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 (including, but not limited to, any loss, claim, damage, liability or action relating to


  
 30 









 
purchases and sales of Offered Certificates), to which such Initial Purchaser, director, officer, employee 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) in any materials or information provided to investors by, or with the approval of, SBA Finance, in connection with the marketing of the offering and sale of the Offered Certificates, including the sales
presentation dated April 1, 2013 (the “Sales Slides”) and any roadshow or other investor presentation made to investors by or on behalf of SBA Finance (whether in person or electronically) (collectively, the “Marketing
Materials”), (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, (iii) the website maintained in compliance with Rule 17g-5 under the Exchange Act by or on behalf of SBA
Finance, the Closing Date Borrowers, the Guarantor or SBA Holdings in connection with the offering of the Offered Certificates, 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 Certificates 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 or controlling person promptly upon demand for any legal or other expenses reasonably incurred by such Initial Purchaser, director, officer, employee 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 or
controlling person of such Initial Purchaser. 
 (b) Each of the Initial Purchasers, severally and not jointly, shall indemnify
and hold harmless SBA Finance, its directors, officers, employees, 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 

  
 31 









 
which SBA Finance or any such director, officer, employee 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 or controlling person for any legal or other expenses reasonably
incurred by SBA Finance or any such director, officer, employee 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 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 similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to 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 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, in the reasonable judgment of the Initial Purchasers, it is advisable for the Initial Purchasers and those
directors, officers, employees and controlling persons to be jointly represented by separate counsel, and in that event the fees and expenses of such separate counsel shall be paid by SBA Finance. No indemnifying party shall (i) without


  
 32 









 
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 Certificates 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 Certificates 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 Certificates purchased under this Agreement, on the other
hand, bear to the total gross proceeds from the offering of the Offered Certificates 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 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


  
 33 









 
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 Certificates 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 32 of the Sales Slides. 

 

	 	8.	Persons Entitled to Benefit of Agreement.

for the sole benefit of only those persons, except as provided in Section 7 with respect to officers, directors, employees 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 Certificates. 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.

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 Certificates; (xiv) the reasonable out-of-pocket fees
and expenses incurred by SBA Finance in connection with attending meetings with prospective purchasers of the Offered Certificates, (xv) expenses of all expenses and application fees incurred in connection with the approval of the Offered

 (b) In addition, if the Trustee shall fail to tender the Offered Certificates 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 Certificates 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 Certificates, 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 Certificates.

	1 	An explanation of the significance of ratings may be obtained from the rating agencies. Generally, rating agencies base their ratings on such material and information,
and such of their own investigations, studies and assumptions, as they deem appropriate. The rating of the securities should be evaluated independently from similar ratings of other securities. A credit rating of a security is not a recommendation
to buy, sell or hold securities and may be subject to review, revision, suspension, reduction or withdrawal at any time by the assigning rating agency. 


	2 	 The Initial Purchasers expect to deliver the Offered Securities on April 18, 2013, which will be the 10th Business Day following the date of pricing of the Offered Securities (such settlement schedule
being herein referred to as “T + 10”). 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 three 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 seven 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 seven Business Days should
consult their own advisor.
