WHEREAS, pursuant to Section 10.01 of the Base Trust Agreement and Section 14 of the Series Supplement, the Trust Agreement may be amended by the Trustor and the Trustee without the consent of any Certificateholders (a) to cure any ambiguity or to correct or supplement any provision therein which may be defective or inconsistent with any other provision therein, or (b) to add, change or eliminate any provisions with respect to matters or questions arising under the Trust Agreement;

WHEREAS, the Trust Agreement currently provides that if the Underlying Securities Issuer ceases to file periodic reports under the Exchange Act and the Trustor determines after consultation with the Securities and Exchange Commission, that under applicable securities laws, rules or regulations the Trust must be liquidated or the Underlying Securities distributed, then an SEC Reporting Failure shall be deemed to occur (and the Trustee shall liquidate or distribute in kind, as directed by the Trustor, any remaining Underlying Securities and distribute any proceeds thereof), such provision having been based on the determination that such provision was necessary to avoid noncompliance with Exchange Act reporting obligations by the Trustor;

WHEREAS, based on consultation with applicable guidance promulgated by the Securities and Exchange Commission, the Trustor has determined that the liquidation of the Trust or distribution of the Underlying Securities is not required to avoid noncompliance with Exchange Act reporting obligations of the Trustor, if and to the extent that the Trustor is able to withdraw the Certificates from listing on the New York Stock Exchange and terminate the Trustor’s Exchange Act reporting obligations with respect thereto;

WHEREAS, the Trust Agreement does not currently provide for any specific actions to be taken if the Trustor determines that the Trust need not be liquidated
