Dear Valued Solutia Customer,

I am writing to inform you that Solutia Inc. announced it has reached a definitive agreement to purchase Southwall Technologies Inc., a leading innovator of energy-saving sputtered films for automotive and architectural markets. This transaction is subject to customary approvals and regulatory processes, with an expected completion in the first quarter of 2012.

Southwall has been a leader in vacuum sputtering technology for more than 25 years with a focus on the window and window film markets. Founded in response to oil embargo of the 70s, Southwall’s products are designed with energy conservation and efficiency in mind. Notably, the world’s first low-emissivity insulating glass product, Heat Mirror® by Southwall was voted by Popular Science as one of the Top 100 Inventions of the 20th Century. The company is also reputed to produce the world’s first multi-layer spectrally selective applied film. Southwall’s R&D facilities are located in Palo Alto, and its
manufacturing plants, capable of producing 48M sq ft annually, are based out of Dresden, Germany.

Solutia believes that the intellectual and manufacturing talent of Southwall will add great value to our Performance Films division.

If you have questions about this announcement, please contact your local sales representative. As always, we appreciate working with you and look forward to continuing to support your
business in the future.

Sincerely,

Dear Sir/Madam

PUBLIC CONSULTATION ON PROPOSED REGULATORY MEASURE TO
ADDRESS SAFETY CONCERNS OVER USE OF GLASS ON BUILDING
FAÇADES
In a modern, densely-built environment like Singapore, glass is used extensively both in the interior and on the exterior of buildings. Tempered glass, because of its high strength property, is often used in parapet walls in the interior, and in claddings and skylight on the exterior of large commercial buildings. In the newer residential buildings, the designs often include full height tempered glass curtain walls to provide panoramic view to homeowners from inside their homes.

2 Since 2006, BCA received reports on about 40 incidents of shattered glass, of which 7 incidents were reported in the past 9 months. Investigations showed that all these incidents involved the use of tempered glass in full-height windows or balcony balustrade. In addition, there were many media reports of incidents of spontaneous shattering of tempered glass used in the interior of buildings.

3 Although the fragments of tempered glass are round-edged, a clump of such fragments could still cause death, if not injury, when falling from height from the glass façade. In addition, the consequence could be dire should a piece of tempered glass panel used in parapet wall or curtain wall spontaneously shatter when a person is leaning on it.

4 In view of the potential dangers posed by glass, BCA is considering introducing some form of performance-based requirements to regulate the use of glass on building façades. BCA would like to seek your comments on one of the two regulatory options proposed in the paper enclosed. Comments/views from
individuals are also welcome.

5 We would appreciate it if your comments/views could reach us before 12 April 2008. You may send your feedback to us in email or snail mail at the
