All three business segments reported higher earnings on improved volume and a favorable sales mix. Total sales volume rose eight percent with each segment reporting increased volume.

• Surfactant gross profit rose by $7.9 million, or 19 percent, on a six percent increase in volume and a favorable mix of higher margin products.
• Polymer gross profit increased by $4.5 million, or 67 percent, as volume rose by 25 percent.
• Specialty Products gross profit increased by $2.5 million, or 100 percent. Volume rose 29 percent and the sales mix of higher margin products was favorable.

SEGMENT RESULTS
($ in thousands)		Three Months Ended March 31
		2010		2009	% Change
Net Sales
Surfactants	$	262,313	$	259,634	+ 1
Polymers		63,110		48,713	+ 30
Specialty Products		11,607		9,796	+ 18
Total Net Sales	$	337,030	$	318,143	+ 6

Net sales rose six percent due to higher sales volume (eight percent), higher foreign sales due to currency translation effect (four percent), partially offset by lower selling prices (six percent).

Surfactant gross profit rose by $7.9 million (19 percent). Sales volume rose by six percent. The majority of the volume and profit improvement was in North America. The sales volume growth came largely in the laundry and cleaning product category. Favorable sales mix also contributed to the higher earnings. Unlike North America, European surfactant profitability declined due to lower sales volume and unit margins declined slightly.

The polymer segment gross profit rose by $4.5 million, or 67 percent. Sales volume grew by 25 percent. The profit improvement was entirely in North America on sales of polyol and phthalic anhydride (PA). Sales volume of polyol in North America rose 19 percent. The majority of the polyol is used in insulation for new or replacement commercial roofs.

PA volume rose 25 percent from depressed 2009 first quarter levels. PA is used as a plasticizer in the automotive, housing, boating and recreational vehicles markets. PA

profitability was up versus the year ago quarter due to lower raw material costs in inventory.

Specialty product gross profit increased by $2.5 million, or 100 percent. The improvement was due to a 29 percent increase in volume, improved sales mix of higher margin products and lower raw material costs.

OTHER INCOME AND EXPENSE

Interest expense declined $0.6 million (32 percent) due to lower debt levels.

The equity in the Philippine joint venture reported a small profit for the quarter compared to a loss a year ago.

The effective tax rate was 34.6 percent versus 34.8 percent a year ago. Recently passed health care legislation and related tax law changes had no impact on the Company’s other expenses and current provision for income taxes.

BALANCE SHEET
($ in millions)	3/31/10		12/31/09		3/31/09
Total Debt	$	103.1	$	104.1	$	132.1
Cash		75.4		98.5		6.8
Net Debt	$	27.7	$	5.6	$	125.3

Net debt rose by $22.1 million during the quarter due to higher working capital levels due to improved sales volumes.

The Company is in discussions with potential lenders to obtain $40 million of additional long term debt financing. The Company currently expects to obtain the debt financing during the second quarter of 2010 and intends to use the proceeds of the financing for capital expenditures, general corporate purposes, as well as, possible bolt-on acquisitions and felt the current interest rate environment was attractive.

OUTLOOK

“Our record first quarter earnings were the result of sustained margins and improved volumes across all three business segments,” said F. Quinn Stepan, Jr., President and Chief Executive Officer. “We believe our core markets provide opportunities for additional profit growth. We are presently adding new capabilities to our surfactant plant in Brazil and expanding our polyol plant in Germany. These and other investments should create the opportunity for us to sustain our earnings momentum.”

Deferred Compensation Plan

The full effect of the deferred compensation plan on quarterly pretax income was $2.2 million of income versus income of $5.2 million last year. The accounting for the deferred compensation plan results in operating income when the price of Stepan Company common stock or mutual funds held in the plan fall and expense when they rise. The Company also recognizes the change in value of mutual funds as investment income or loss. The quarter end market prices of Stepan Company common stock are as follows:

2010	2009		2008
3/31	12/31	3/31	12/31
$55.89	$64.81	$27.30	$46.99

that information is an appropriate measure for evaluating the Company’s operating performance.

These measures should be considered in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

Table III

Effects of Foreign Currency Translation

The Company’s foreign subsidiaries transact business and report financial results in their respective local currencies. As a result, foreign subsidiary income statements are translated into U.S. dollars at average foreign exchange rates appropriate for the reporting period. Because foreign exchange rates fluctuate against the U.S. dollar over time, foreign currency translation affects period-to-period comparisons of financial statement items (i.e. because foreign exchange rates fluctuate, similar period-to-period local currency results for a foreign subsidiary may translate into different U.S. dollar results). For the quarter ending March 31, 2010, the U.S. dollar weakened against nearly all the foreign currencies in the locations where the Company does business, when compared to the exchange rates for the quarter ending March 31, 2009. Consequently, reported net sales, expense and income amounts for the quarter ending March 31, 2010, were higher than they would have been had the foreign currency exchange rates remained constant with the rates for the same periods of 2009. Below is a table that presents the impact that foreign currency translation had on the changes in consolidated net sales and various income line items for the first quarter:

				Increase Due
