Item 1122 of Regulation AB. Compliance with Applicable Servicing Criteria


The Bank of New York Mellon (in its role as trustee) has been identified by the registrant as
participating in the servicing function with respect to the asset pool held by the PPLUS Trust
Series GSC-4 (the Servicing Party). The Servicing Party has completed a report on assessment of
compliance with the servicing criteria applicable to it (a Servicing Report), which Servicing
Report is attached as  exhibit 33.1 to this Form 10-K. The Servicing Party has provided an
attestation report (an Attestation Report) by KPMG LLP, Independent Registered Public
Accounting Firm, which report is  attached as  exhibit 34.1 to this Form 10-K. Each of   the Servicing Report and   the Attestation Report  identified  material
instances of noncompliance with servicing criteria  1122(d)(2)(i) as described therein. While Regulation AB does not contemplate identifying noncompliance on an
individual transaction basis, the Servicing Party has confirmed to the
Registrant that no instances of noncompliance with Regulation AB were discovered
with respect to the PPLUS trust series that were part of the statistical sample
used in preparing the Servicing Report. The Servicing Party has informed the
Registrant that the Servicing Party cannot provide any assurances that had an
analysis been done of each and every transaction included in the platform
(including all PPLUS trust series forming part of the platform), that additional
instances of noncompliance would not have been discovered. However, the
Servicing Party has informed the Registrant that it has no reason, based on the
sampling and analysis done, to believe that there are any instances of
noncompliance with those PPLUS trust series that were not part of the sampling
procedures.
