Bomlitz, Germany - May 30, 2008

June 1, 2008 - Across a significant portion of our portfolio, demand continues to be strong driving further need for investment and increased raw materials consumption. In response to these investments as well as dramatic increases in raw material, transportation and energy costs, Dow Wolff Cellulosics today announced that it will increase prices globally across its entire product portfolio by up to 15 percent, depending on specific grades and market segments. In some geographies, the price increase could be considerably above this level due to additional costs to serve. The price increases are effective immediately as of June 1, 2008 or as contracts allow.

The products impacted by this announcement include the entire cellulose derivatives line and several companion chemistries:

• Methylcellulosics: METHOCEL™ and WALOCEL™ Hydroxypropyl Methylcellulose (HPMC), Hydroxyethyl Methylcellulose (HEMC) and Methyl Cellulose (MC) ethers
• Other Cellulose Ether products: ETHOCEL™ Ethylcellulose (EC) and WALOCEL™ C Carboxymethyl Cellulose (CMC)
• Companion chemistries: POLYOX™ Water Soluble Resins, DOW™ Latex Powders and UCON™ Fluids

“Price adjustments will partially offset a number of cost pressures which we cannot ignore, such as a step change in cellulose pulp costs and tight pulp supply, record level hydrocarbon & energy costs, and sharp freight increases across our business,” said Eunice Heath, global marketing and sales director, Dow Wolff Cellulosics. “In addition, they will allow us to continue to invest in products and technologies that will fulfill the future needs of our customers and markets.”
