 Complete failure of the roof membrane, as stated by GAF consultant from Trinity ERD  Elastomeric roof material did not completely adhere to roof deck causing it to pull apart during rain and snow/ice melt ◦ Roof deck not completely cleaned ◦ Multiple substrates for the roof membrane to adhere to (foam/concrete/metal) ◦ Roof corrugations caused ponding of water and ice creating ice and snow slabs up to 1 ton ◦ Roof membrane not evenly applied on roof surface ◦ Open transition points at top flutes

 GAF & Riddiford completed a roof inspection  Intermediate repairs completed that will take us through the winter & spring ◦ Hand application (brush on) of top coat sealant in all twelve flutes ◦ Scope of the intermediate repairs  Repairs to the flexible flashing  Repairs to the blistered and delaminated areas ◦ 125 gallons of GAF top coat material used  Reduced the roof leaks by approximately 70%  Roof will develop more leaks

 Remove roof presently damaged roof membrane & substrate materials  Remove corrugations with 2 layers foam insulation  Install knife plate snow & ice breakers  Treat foam to metal deck transitions with flash grade topcoat  Install base & finish coats of GAF Elastomeric membrane roofing  Complete work in two phases ◦ Phase 1 complete repairs in 1-3 flutes during 4-5 weeks shutdown summer 2010 ◦ Phase 2 complete repairs to remaining flutes during long shutdown 2012

 GAF standing behind the roof warranty  GAF hired Roof Consultant Trinity ERD to evaluate and identify repair solutions including laboratory testing of materials  GAF, Riddiford, & Trinity ERD has met with the lab to start development of a repair plan  Repair plan due from GAF within the next couple of weeks
