as we have considered relevant and necessary as a basis for the opinions hereinafter expressed.

We have relied solely and without independent verification upon (i) a certificate of an officer of Evergreen Canada dated November 7, 2012 (the “Evergreen Canada Officer’s Certificate”), and (ii) a certificate of an officer of Pactiv Canada dated November 7, 2012 (the “Pactiv Canada Officer’s Certificate”, and collectively with the Evergreen Canada Officer’s Certificate, the “Officer’s Certificates”), each in the form delivered to you.
