specializes in half-inch to four-inch fittings and serves the plumbing, pool and spa, industrial, irrigation and
retail markets in the United States. LASCO’s product mix is very complementary to our existing range of pipe
and fittings products primarily with diameters of four or more inches and will bring additional fittings products

the United States, LASCO can promptly supply its customers across North America.

The proposed transaction is subject to customary closing conditions, including the expiration or termination
