PHILADELPHIA, PA, October 19, 2006 — Rohm and Haas Company (NYSE: ROH) today reported third quarter 2006 sales of $2,065 million, a 7 percent increase over the same period in 2005, reflecting broad based growth across all businesses. Electronic Materials posted another record quarter, and Coatings sales were bolstered by solid demand in Architectural and Functional Coatings. The company reported third quarter earnings from continuing operations of $189 million, or $0.86 per share, compared to $163 million, or $0.73 per share, for the third quarter of 2005. This quarter’s results include $.03 per share mainly due to the favorable settlement of tax contingencies. The comparative year’s results included approximately $7 million after-tax, or $0.03 per share of costs associated with the shutdowns necessitated by the 2005 hurricanes in the Gulf Coast region of the United States.

Third Quarter

(in millions, except per share amounts)	2006		2005		% Change
Sales	$	2,065	$	1,927		7	%
Earnings from Continuing Operations	$	189	$	163		16	%
Earnings per Share from Continuing Operations (diluted)	$	0.86	$	0.73		18	%

“This quarter’s results again reflect the continued strength in our Electronic Materials franchise, as well as solid demand across most of our chemicals businesses,” said Raj Gupta, chairman, president and chief executive officer. “Despite some evidence of slowing in the building and construction market in North America, demand across our key markets still remains strong, and our global reach is enabling us to grow faster in the emerging markets. This quarter’s results maintain the momentum of solid earnings growth we have demonstrated over the past several years.”

Gupta further noted that the company is effectively navigating the challenging environment of volatile prices for key raw materials. “We are experiencing extraordinarily high costs for key petrochemical raw materials, despite the recent drop in oil prices,” Gupta explained.

Third Quarter 2006 Business Results

Coatings

Sales in the Coatings segment of $700 million increased 5 percent over the third quarter of 2005. The improvement was attributed to higher selling prices to recover rising raw materials, higher demand, particularly in emerging markets, along with the favorable impact of currencies.

Architectural and Functional Coatings sales, which account for the majority of sales in the Coatings segment, increased 6 percent over the comparable period, due to higher pricing necessary to recover rising raw material costs. In addition, the business saw strong demand in the emerging markets, particularly China, Turkey, India and Latin America, along with more modest growth in North America. New products, particularly the low-VOC product lines and other innovative and environmentally friendly products, continue to gain acceptance.

Powder Coatings sales increased 3 percent over the prior year period, driven primarily by higher selling prices and the favorable impact of stronger European currencies, which more than offset the impact of lower demand.

Third quarter earnings for the Coatings segment were $64 million, including $2 million after-tax of restructuring charges, versus $74 million in earnings in the same period in 2005. The significant run-up in raw material costs during the quarter, along with spending to fund growth initiatives, more than offset the favorable impact of higher selling prices and currencies.

Monomers

Sales of $500 million were up 18 percent from $422 million in the same period a year ago. Third party sales of $163 million increased 8 percent from the prior year period, primarily due to higher volumes.

Monomers earnings of $42 million for the quarter increased from $30 million in the same period a year ago. Prior period results included $12 million, after-tax, of expenses associated with an unplanned plant outage in July 2005, as well as the precautionary shutdown of the Deer Park, Texas facility in September, 2005 due to Hurricane Rita. This quarter’s earnings reflect the favorable impact of higher volume, improved operations and lower energy costs, which were partially offset by higher raw materials and lower selling prices to third party customers. During the quarter, approximately 60 percent of Monomers earnings was generated by sales to the downstream businesses, as compared to approximately 25 percent in the same period last year.

Performance Chemicals

Sales of $447 million were up 6 percent over the comparable period in 2005 driven by higher demand, particularly in the Consumer and Industrial Specialties and Process Chemicals businesses, with slightly higher selling prices, and a favorable impact of currencies.

• Sales in Plastics Additives were up 3 percent over the prior year period, reflecting higher selling prices, and the favorable impact of currencies. While overall demand was down slightly, due to some slowing in North America, the business continues to see stronger demand in its packaging and building and construction segments in the emerging markets of China and Latin America.

• Consumer and Industrial Specialties sales increased 6 percent over the same period last year, largely due to increased demand for biocides and specialty products across most regions.

• Sales for Process Chemicals were up 4 percent from the comparable period a year ago. There continues to be strong demand for ion exchange resins, particularly in Asia. Higher selling prices and the favorable impact of currencies were also positive factors in the year-over-year sales increases.

Performance Chemicals earnings were $42 million in the quarter, down from $44 million in the prior year period, reflecting higher raw material costs and increased spending to support business development and new products, which more than offset the favorable impact of higher pricing.

Electronic Materials

Quarterly sales of $402 million were up 15 percent over the same period in 2005, primarily due to strong demand across all businesses, in all regions with Asia-Pacific posting the strongest growth. The pass through of precious metal costs in the Packaging and Finishing business impacted the Electronic Materials sales change by 3 percent. The business posted its fifth consecutive quarterly sales record as it continued to deliver innovative technologies to meet the needs of this dynamic marketplace. Sales of advanced technology products, such CMP pads and slurries, advanced photoresists, and anti-reflective coatings, posted a 19 percent increase over the prior year period. Sequentially, third quarter 2006 sales for Electronic Materials were up 2 percent over the second quarter, reflecting the continuing strength of the overall electronics markets and the penetration of our advanced technology product lines.

• Semiconductor Technologies sales increased 16 percent over the same period in 2005, driven by higher demand for CMP pads and slurries, along with strong sales of advanced photoresists and related products in all regions.

• Circuit Board Technologies sales were up 8 percent over the same period in 2005, reflecting ongoing strength in Asia-Pacific, whose sales increased 14 percent versus a year ago, which more than offset decreased demand in North America and Europe.

• Packaging and Finishing Technologies sales were 17 percent higher than the same period a year ago, primarily driven by revenues generated from the pass through of precious metal prices. Process sales were down slightly in the quarter.

Third quarter 2006 earnings for Electronic Materials were a record $62 million, 27 percent higher than the third quarter of last year, reflecting the continued strong demand across all the Electronic businesses, particularly higher sales of the advanced technology product lines.

Salt

Sales of $174 million were up 7 percent versus the same period a year ago, due to higher selling prices, and the favorable impacts of product mix management and currency, which more than offset a slight decline in demand associated with decreased shipments of ice control salt.

The business recorded earnings of $4 million for the quarter, up $5 million from a loss of $1 million in the prior year period. This quarter’s results includes a $1 million after-tax charge for restructuring. The third quarter of 2005 results include $1 million after-tax of costs associated with operating disruptions caused by Gulf Coast hurricanes. Higher selling prices to offset increases in production and distribution costs, and a shift in sales mix toward higher margin products, both contributed to the change in earnings.

Adhesives and Sealants

Sales of $179 million were up 2 percent versus the comparable period in 2005, due to the favorable impact of currencies and slightly higher pricing. Growth in the core business segments offset the impact of prior portfolio management initiatives.

Earnings of $15 million were up $5 million versus results in the third quarter of 2005, which included a non-cash impairment charge of $3 million, after-tax. Improved product mix, higher selling prices and the favorable impact of currencies were partially offset by higher raw materials.

Corporate

Corporate expense of $40 million, after-tax, for the quarter was down from $43 million, after-tax, in the third quarter of 2005. The change reflects lower interest expense and environmental accruals, and higher interest income, partially offset by funding of special initiatives, and restructuring charges.

Third Quarter 2006 Regional Sales Performance

North American sales of $1,042 million were up 5 percent over the comparable period in 2005, primarily the result of higher selling prices. While overall demand in the region was flat, there was solid growth in the decorative coatings segment of the Architectural and Functional Coatings business. The higher pricing across most of the chemicals businesses reflected efforts to mitigate the impact of higher raw material costs. European sales were $507 million for the quarter, up 5 percent versus the same period last year, reflecting favorable currencies and higher demand, primarily in the Plastics Additives and Consumer and Industrial Specialties businesses. Asia-Pacific sales were $427 million, a 13 percent increase over the same period last year, with all businesses contributing, led by Electronic Materials and Performance Chemicals. Latin American sales of $89 million in the quarter were 19 percent higher than the same period last year, reflecting increased demand, higher selling prices and the favorable impact of currencies. The higher demand was experienced primarily in the Coatings, Plastics Additives, and Process Chemicals businesses.

Comments on the Third Quarter 2006 Income Statement

Gross Profit of $602 million in the quarter was 6 percent higher than the same period in 2005, the result of increased selling prices, higher demand, lower environmental accruals, and the absence of prior year charges for a temporary Monomer production outage, partially offset by higher raw materials and freight costs. Gross Profit Margin in the quarter was 29.2 percent, compared to 29.6 percent.

Selling and Administrative (S&A) spending of $247 million was $13 million, or 6 percent higher that the same period in 2005, largely reflecting increased spending to support growth initiatives. As a percentage of sales, S&A spending of 12 percent was virtually unchanged when compared to the same period in 2005.

Research spending of $71 million was $5 million, or 8 percent higher, versus the same period a year ago, due largely to increased spending to support growth projects in Electronic Materials, Coatings and Performance Chemicals.

Interest expense for the quarter was $21 million, down 25 percent from the same period in 2005, primarily due to lower levels of debt and a lower overall effective interest rate.

Income tax expense for the quarter was $69 million, reflecting an effective tax rate of 26.4 percent, as compared to income tax expense of $77 million, or an effective tax rate of 31.6 percent in the prior year period. The lower tax expense includes $6.8 million mainly due to the favorable settlement of tax contingencies.

Year-To-Date 2006 Performance

Sales for the nine months ended September 30, 2006 were $6,204 million, a 5 percent increase over the comparable period in 2005, driven by broad -

based growth in demand across most chemical businesses and the strength of Electronic Materials. Higher selling prices, necessary to help balance continued high raw material and energy costs, were partially offset by an unfavorable impact of currencies. Earnings from continuing operations for the first nine months of 2006 were $588 million, or $2.65 per share, compared to $488 million, or $2.17 per share in 2005. Increased demand, higher selling prices, and lower interest expense more than offset the impact of higher raw material, energy, freight and operating costs, along with higher spending on growth initiatives. During the first nine months of 2005, significant favorable tax adjustments were more than offset by charges for restructuring, debt extinguishment, costs associated with the shutdowns necessitated by the 2005 hurricanes in the Gulf Coast region of the United States, and the acceleration of stock-based compensation for retirement-eligible employees, for a net unfavorable impact of $0.07 per share.

Full-Year Guidance

Gupta noted that the macro economic outlook remains somewhat uncertain, given the volatile nature of petroleum based feedstocks and energy costs, some slowing in the housing market in North America, and the potential impact of these factors on consumer spending late in the year. “Despite these conditions, we have demonstrated our ability to use innovation and differentiation to grow our businesses, particularly Architectural and Functional Coatings and Electronic Materials. Combined with our geographic position, particularly in emerging markets, we expect full-year sales growth in the approximately 5 percent range, yielding record annual sales of $8.3 billion and earnings from continuing operations in the $3.40-$3.45 range. ”
