Solutia to Acquire Southwall Technologies Inc.

Creates powerhouse of world-class innovation, technology and commercial films expertise

ST. LOUIS and PALO ALTO, October 7, 2011 -- Solutia Inc. (NYSE: SOA), a market-leading performance materials and specialty chemicals company, and Southwall Technologies Inc. (NASDAQ: SWTX), a leading innovator of energy-saving films and glass products for automotive and architectural markets, today announced that they have signed a definitive agreement providing for Solutia to acquire Southwall for $13.60 per share of Southwall common stock in cash.  The transaction, which has been approved by the boards of directors of both companies, has an aggregate equity purchase price of approximately $113 million.  The acquisition will be funded by Solutia from existing cash on hand.

“This acquisition positions Solutia as the world leader in advanced sputtering technology, combining the industry’s leading commercial expertise with next-generation innovation capabilities to provide advanced film solutions to the premium window film and electronics markets,” said Jeffry N. Quinn, chairman, president and chief executive officer of Solutia Inc.  “Our growth strategy remains focused on enhancing our portfolio through synergistic bolt-on acquisitions that allow Solutia to better serve high-growth markets and support the success of our existing businesses.  This is just one component of our strategy to put our strong cash flow to work to create value for our shareholders.”

The acquisition will secure Solutia’s access to Southwall’s proprietary XIR® technology, a key base material for the Company’s high-growth V-Kool® premium aftermarket window films.  In addition, the acquisition adds state-of-the-art manufacturing capacity and proprietary capabilities to support the fast-growing demand for high-tech films for the electronics market and positions Solutia to provide a broader range of product solutions. This includes a new product offering in which transparent film is encapsulated between Saflex® polyvinyl butyral interlayers to form a protective barrier in laminated glass against the harmful effects of the sun.

 “We look forward to realizing the potential of Southwall’s portfolio of energy efficiency solutions as we combine our innovation in sputtering technology with Solutia’s commercial and market expertise,” said Dennis Capovilla, president and chief executive officer of Southwall Technologies Inc.  “Together we will focus on the delivery of next-generation films to our customers that achieve unmatched levels of solar performance and optical clarity.”

Under the terms of the agreement, it is anticipated that a subsidiary of Solutia will commence a tender offer for all of the outstanding shares of Southwall common stock no later than October 25, 2011.  Southwall stockholders will receive $13.60 per share in cash for all outstanding shares of Southwall common stock tendered in the offer and accepted for payment by Solutia, representing a 45% premium to the closing price per share of Southwall common stock on October 6, 2011.  The closing of the tender offer is subject to customary terms and conditions, including the tender of a majority of the outstanding shares of Southwall and the receipt of regulatory approvals.  Following the successful completion of the tender offer and following the receipt of stockholder approval, if necessary, the agreement provides for Southwall to merge with a subsidiary of Solutia and become a wholly-owned subsidiary of Solutia, with all shares of Southwall common stock then outstanding being converted into the right to receive the offer price in cash.

The tender offer is expected to be completed in the fourth quarter of 2011.  Certain funds affiliated with Needham Funds, together with Dolphin Direct Equity Partners, L.P., which collectively hold shares of Southwall common stock and convertible preferred stock equal to approximately 63% of the outstanding shares of Southwall common stock on an as-converted basis, have entered into tender and support agreements with Solutia pursuant to which they have agreed to support the transaction and tender their shares in the offer.

Moelis & Company LLC and Kirkland & Ellis LLP acted as advisors to Solutia on this transaction.  Needham & Company, LLC, Seven Hills Group LLC and Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP acted as advisors to Southwall on this transaction.

In an effort to enhance communications, Solutia has created a supplemental video available on its website and YouTube channel that focuses on this announcement.
