WITNESSETH:

WHEREAS, Ply Gem Midco, LLC (formerly known as Ply Gem Midco, Inc., and formerly known as Pisces Midco, Inc.), a Delaware limited liability company (the “Predecessor Company”), any Existing Guarantors and the Trustee have heretofore become parties to an Indenture, dated as of April 12, 2018 (as supplemented by the First Supplemental Indenture, dated as of April 12, 2018, the Second Supplemental Indenture, dated as of April 12, 2018, the Third Supplemental Indenture, dated as of April 13, 2018, and the Fourth Supplemental Indenture, dated as of October 15, 2018, and as further amended, supplemented, waived or otherwise modified, the “Indenture”), providing for the issuance of Notes in series;

WHEREAS, the Predecessor Company has merged with and into the Successor Company (the “Merger”), with the Successor Company being the surviving entity;

WHEREAS, Article V of the Indenture provides that the Predecessor Company shall be permitted to merge with or into any Person, provided that upon any such merger such resulting, surviving, or transferee Person shall expressly assume all the obligations of the Predecessor Company under the Notes and the Indenture by executing and delivering to the Trustee a supplemental indenture or one or more other documents or instruments in form reasonably satisfactory to the Trustee, and that thereupon the Predecessor Company shall be relieved of all obligations and covenants under the Indenture;
