We have acted as special counsel in the State of Washington to Hytec, Inc., a Washington corporation (the “Washington Guarantor”) in connection with certain obligations of its affiliated companies, Tomkins, Inc., a Delaware corporation formerly known as Pinafore, Inc.

This opinion is delivered in connection with the filing of a registration statement on Form F-4 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of $1,150,000,000 aggregate principal amount of the Issuers’ 9% Senior Secured Second Lien Notes due 2018 (the “New Notes”) in connection with an offer by the Issuers to issue the New Notes in exchange for the Issuers’ outstanding 9% Senior Secured Second Lien Notes due 2018 (the “Old Notes”). The Old Notes are, and the New Notes will be, issued pursuant to an Indenture dated as of September 29, 2010, as supplemented by the First Supplemental Indenture dated as of November 18, 2010, the Second Supplemental Indenture dated as of December 21, 2010, the Third Supplemental Indenture dated as of December 23, 2010, the Fourth Supplemental Indenture dated as of January 20, 2011, the Fifth Supplemental Indenture dated as of February 23, 2011, the Sixth Supplemental Indenture dated as of February 24, 2011 and the Seventh Supplemental Indenture dated as of March 3, 2011 (collectively, the “Indenture”) entered into among the Issuers, the Guarantors named therein, and Wilmington Trust FSB, as trustee (the “Trustee”) and collateral agent.
