     ·  Utz-Helmuth Felcht elected new member of Board

     ·  Strategic focus on core businesses; operational focus on growth, innovation and profitability

At the tenth Annual General Meeting of March 8, 2007, held in the Congress Center Basel (Switzerland), the shareholders of Ciba Specialty Chemicals Holding Inc. approved all the motions proposed by the Board of Directors. The 1,193 shareholders in attendance represented 16,340,552 of the votes, or 23.7 percent of the 69,064,617 registered shares.

The Annual General Meeting approved by a large majority the proposal by the Board of Directors for a dividend of CHF 3 per share. The shareholders also approved the discharge of the Board of Directors and the management from liability for their activities in 2006.

With a large majority, the Annual General Meeting elected Utz-Hellmuth Felcht to the Board as a new non-executive director for a period of three years. Felcht (60, German) is an independent business consultant with broad experience in the chemical industry, most recently as CEO of Degussa AG. In accord with the Board’s proposals, Erwin Heri and Uli Sigg were reelected as members of the Board for a period of four years.

Shareholders approved an amendment to the Articles of Association as well as the introduction of electronic voting at Annual General Meetings. The Annual General Meeting also confirmed Ernst & Young AG, Zurich, as Auditors and Group Auditors.

In addition, the company announced that it may now use the name “Ciba” without the addition of “Specialty Chemicals” due to a new agreement with Novartis. The name change will be implemented incrementally and will be concluded with the expected renaming of the holding company at the Annual General Meeting 2008.

Presidential address by Armin Meyer

In his address, Armin Meyer, Chairman of the Board and Chief Executive Officer of Ciba Specialty Chemicals, commented on the 2006 financial results as well as the company’s strategy.

“2006 was a year of transformation for Ciba Specialty Chemicals. We refined our strategic direction and, after divesting Textile Effects, strengthened our focus on the core businesses Plastic Additives, Coating Effects and Water & Paper Treatment. We also launched the Operational Agenda to increase our efficiency across the company and to accelerate our growth and innovation. And last but not least, we improved our sales as well as our underlying profitability.

We will exploit the sizeable potential of our core businesses Plastic Additives and Coating Effects through targeted investments in growth and innovation, whereas in Water & Paper Treatment we will concentrate on improving profitability. Our niche businesses have a clear growth focus. I am confident that we have an effective strategy in place and are implementing the right operational measures to get Ciba fully back on track.”

Brendan Cummins explains operational priorities

Brendan Cummins, Chief Operating Officer and CEO Designate of Ciba Specialty Chemicals, explained the company’s operational priorities.

“The focus of the Operational Agenda is to stay ahead through innovation, clever marketing and efficient processes. Managing R&D effectively is a key component. We also see considerable potential to improve profitable growth by leveraging our excellence in marketing and sales. At the same time, we are harmonizing our global business processes, optimizing our global production network with standardized processes and streamlining our global presence. Ciba is a strong company with a solid base, unique innovation and talented people. By tapping this potential, growing profitably and improving our efficiency, we will shape our future.”
