The information below has been provided in accordance with
General Instruction J to Form 10-K:



Item 1122 of Regulation AB. Compliance with Applicable Servicing
Criteria.



The Trustee has been identified as a party
participating in the servicing function during the reporting period with respect to the pool assets held by the issuing entity.
The Trustee’s report on an assessment of compliance with the servicing criteria applicable to it during the Issuing Entity’s
fiscal year ending December 31, 2013 and an attestation report by a registered independent public accounting firm regarding the
Trustee’s related report on assessment are attached as exhibits to this Form 10-K.



Except as disclosed below, neither the report
on assessment nor the related attestation report has identified any material instances of noncompliance with the servicing criteria
described in the report on assessment as being applicable to the Trustee. With respect to the exceptions identified below, the
Trustee has confirmed that none of the identified instances of noncompliance related to or affected STRATS Trust for Allstate Corporation
Securities, Series 2006-3.



Exceptions:



The Trustee’s report on assessment
and the related attestation report have identified material noncompliance with two servicing criteria applicable to the Trustee:

are maintained in accordance with the transaction agreements and applicable Commission requirements. Specifically, such reports
must be prepared in accordance with timeframes and other terms set forth in the transaction agreements.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Noncompliance:
The Trustee indicates that during the reporting period, certain reports to investors were not prepared in accordance with the timeframes
and other terms set forth in the related transaction agreements.



Remediation:
The Trustee further indicates that when its management became aware of such instances (a) controls designed to prevent such occurrences
in the future were implemented and (b) impacted investors received either (i) reports containing accurate information that were
not previously distributed or (ii) revised reports notifying investors that previous information in reports were revised with corrected
information. Reports were delivered to investors and filed on EDGAR on Form 10-D or Form 10-D/A, as required.



| | · | Servicing criterion 1122(d)(3)(ii) contemplates that amounts due to investors are allocated and remitted in accordance with
timeframes, distribution priority and other terms set forth in the transaction agreements.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Noncompliance:
The Trustee indicates that during the reporting period, for an auto transaction in its platform, certain amounts due to the related
investors were not remitted in accordance with the timeframes set forth in the related transaction agreements.



Remediation:
The Trustee further indicates that when its management became aware of such instance (a) the transaction was properly set-up on
the related company’s automated payment system and other controls designed to prevent such occurrences in the future were
implemented, (b) notice of the failure was made available to investors in the transaction through the facilities of DTC on August
21, 2013 and on a Form 10-D filed on EDGAR on the same date, and investors were offered compensation for the one day remittance
delay, and (c) the investor report was not revised as it accurately reflected the amounts due to investors and available for payment
