Oldcastle Glass^® Acquires Antamex International, Inc.

Santa Monica, CA – August 9, 2006 – Oldcastle Glass^® has acquired Toronto-based Antamex International, Inc., a privately-held supplier of high-performance curtain wall systems and engineering design services for commercial, institutional and multi-story condominium construction markets.

Antamex will become the cornerstone of Oldcastle Glass^® Envelope™, a comprehensive range of architectural glass, operable windows, storefronts, doors and curtain wall products designed to close the building envelope. By narrowing the number of vendors required in building construction projects, Oldcastle Glass^® Envelope™ will allow architects, developers and glazing contractors to reduce inherent risks, minimize costs, and close the building envelope more quickly and efficiently.

“By virtue of its extensive engineering design capability, outstanding market reputation, and international project portfolio, Antamex participates in commercial construction projects from their earliest stage,” said Ted Hathaway, CEO, Oldcastle Glass^®. “This acquisition puts Oldcastle Glass^® in a unique position to seamlessly integrate Building Envelope products and services, including architectural glass and custom-engineered curtain wall. Antamex is a world-class company and a superb strategic fit with our Building Envelope strategy.”

“Oldcastle Glass^® provides Antamex with significant financial resources and substantial capabilities in high-performance architectural glass products and services throughout North America. This partnership will strengthen our company as we extend our geographic reach, enhance our product offerings, and bring greater value to our customers,” said Elio Toffoli, Antamex’s current President and CEO, who will continue to lead the company after the acquisition.
