Item 1112(B) of Regulation AB. Significant Obligors of Pool Assets (Financial Information)

The underlying securities issued by The Goldman Sachs Group, Inc. (the “underlying securities issuer” or the “significant obligor”) constitute the only pool assets held by PPLUS Trust Series GSC-4. Pursuant to Item 1100(c)(2) of Regulation AB, financial information relating to the significant obligor is not included in or incorporated by reference into this annual report on Form 10-K. For information with respect to the underlying securities held by PPLUS Trust Series GSC-4, please refer to The Goldman Sachs Group, Inc.’s (Commission file number 001-14965) periodic reports, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and other information on file with the Securities and Exchange Commission (the “SEC”). You can read and copy these reports and other information at the public reference facilities maintained by the SEC at Room 1580, 100 F Street, NE, Washington, D.C. 20549. You may obtain copies of this material for a fee by writing to the SEC’s Public Reference Section of the SEC at 100 F Street, NE, Washington, D.C. 20549. You may obtain information about the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. You can also access some of this information electronically by means of the SEC’s website on the Internet at http://www.sec.gov, which contains reports, proxy and information statements and other information that the underlying securities issuer has filed electronically with the SEC.

Although we have no reason to believe the information concerning the underlying securities or the underlying securities issuer contained in the underlying securities issuer’s Exchange Act reports is not reliable, neither the depositor nor the trustee participated in the preparation of such documents, or made any due diligence inquiry with respect to the information provided therein. No investigation with respect to the underlying securities issuer (including, without limitation, no investigation as to its financial condition or creditworthiness) or of the underlying securities has been made. You should obtain and evaluate the same information concerning the underlying securities issuer as you would obtain and evaluate if your investment were directly in the underlying securities or in other securities issued by the underlying securities issuer. There can be no assurance that events affecting the underlying securities or the underlying securities issuer have not occurred or have not yet been publicly disclosed which would affect the accuracy or completeness of the publicly available documents described above.

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.

Item 1123 of Regulation AB. Servicer Compliance Statement

The Bank of New York Mellon has been identified by the registrant as the servicer with respect to the asset pool held by the Trust. The Bank of New York Mellon has completed a statement of compliance with applicable servicing criteria (a “Compliance Statement”), signed by an authorized officer of The Bank of New York Mellon. The Compliance Statement is attached as an exhibit to this Form 10-K.
