Segment Results - Reported Basis

In the Aqualon Group, net sales increased 17% and profit from operations increased $5.7 million, or 16%, in the fourth quarter as compared with the fourth quarter of 2005. Net sales for the year increased 18% and profit from operations increased $31.9 million, or 21%, as compared to the prior year.

All Aqualon businesses had increased sales in the fourth quarter as compared to the prior year. In the aggregate, the sales increase was driven by 17% higher volume, increased pricing of 3% and favorable rates of exchange of 2%, partially offset by 5% unfavorable product mix. Overall the Company's guar and guar derivatives acquisition and consolidation of Hercules Tianpu, a methylcellulose joint venture in China, accounted for approximately a 10% sales increase.

"Aqualon continued to grow its businesses both organically and through acquisitions and joint ventures," noted Mr. Rogerson. "Pricing continued to show improvement while sales volume continued to be strong."

Coatings & Construction sales increased 13% in the fourth quarter of 2006 as compared to the same period of last year, primarily due to 14% higher volume, 3% favorable rates of exchange and 1% increased pricing, partially offset by 5% unfavorable product mix. Sales of products in the Middle East and Asia coatings markets were especially strong during the fourth quarter, while North America growth was lower. Sales into the construction industry continued to be strong in Eastern Europe and other emerging markets. Pricing improvement in the segment turned positive during the fourth quarter, as increases were achieved in coatings, partially offset by 1% lower methylcellulose pricing into the construction industry. Pricing into construction was flat sequentially from the third quarter 2006, reversing the declining trends experienced in previous quarters.

Regulated Industries sales increased 12% in the fourth quarter of 2006 as compared to the same period of last year, due to an 11% improved product mix, 3% increased prices and 2% favorable rates of exchange, partially offset by 4% lower volumes. Volumes were lower in food markets, resulting in a higher product mix in the pharmaceutical and personal care markets. Excluding the lower food volumes, volume increased in most markets and regions. Price increases were achieved in the food and pharmaceutical markets, whereas personal care prices were lower.

Energy & Specialties sales increased 24% in the fourth quarter of 2006 as compared to the same period of last year. The increase was due to 15% higher volume/mix, 8% higher price, and 1% favorable rates of exchange. The guar acquisition accounted for a 20% sales increase. The natural gas and oil services sector demand continues to be strong and price increases were achieved across many of the specialty products families.

Aqualon Group's increased profit from operations was due to higher sales volume and the associated contribution margin, as well as increased prices, partially offset by higher raw material costs. Selling, general and administrative (SG&A) costs were higher compared to the prior year, primarily reflecting increased corporate support costs, sales and marketing, business management, and technology costs incurred to support growth initiatives. Operating profit also included a $3.6 million gain on sales of excess land at two current production sites.

In the Paper Technologies and Ventures Group ("PTV"), net sales in the fourth quarter increased 13% and profit from operations increased $13.1 million, or 122%, compared with the same quarter in 2005. Net sales for the year ended December 31, 2006 increased $58.0 million, or 6%, and profit from operations increased $19.4 million, or 32%, as compared to the prior year.

Paper Technologies sales increased 12% as compared to the fourth quarter of 2005, due to 10% increased volume, 5% increased price and 3% favorable rates of exchange, partially offset by an unfavorable mix of 6%. Volume growth was achieved in the Americas and in Asia, whereas Europe was lower. Asia volumes remained strong, increasing 24% compared to the prior year, and North America increased 13% for the same period. The increase in North America volumes was primarily due to a marketing and manufacturing alliance for rosin size products established in 2006. Mill closures and bankruptcies, primarily in Southern Europe, continue to negatively impact overall results in Europe. Increased pricing was achieved in all regions of the world with the largest increase obtained in North America. The unfavorable mix primarily reflects higher sales of lower priced functional products in both North America and the emerging Asian markets.

Venture sales increased 14% primarily due to 3% higher price, 13% improved product mix and 2% favorable rates of exchange, partially offset by 4% lower volume. Pricing reflects increases in water management, lubricants and pulping products. The improved mix reflects higher sales of water management, lubricants and adhesive products.

PTV's increased profit from operations for the fourth quarter reflects higher volumes and improved selling price, partially offset by higher raw material and SG&A costs. Price increases of $11.0 million exceeded raw material cost increases of $7.5 million. Severance, restructuring and other exit costs in the fourth quarter of 2006 were $2.3 million as compared to $3.6 million in the same period of 2005. SG&A costs were higher than the prior year primarily due to increased corporate support costs and bad debt accruals, partially offset by savings from restructuring efforts throughout last year. Also, legal fees associated with patent defense costs were significantly lower than the prior year. Operating profit included a $2.9 million gain on the sale of excess land at a current production site.

"Improved performance in the Americas helped offset the continued challenging conditions in the Western European paper market. Our strategy of improving product mix through innovation and of increasing selling prices to reflect value continues to show progress," commented Mr. Rogerson.

Outlook

"The results achieved in 2006 were a direct product of the strategy executed over the past several years focusing on growth, continuous productivity improvement and cash flow generation," noted Mr. Rogerson. "While we have made significant progress, there are many opportunities ahead of us. We will continue to execute our strategy to deliver differentiated value to our customers, and target consistent double digit EPS and cash flow growth to create increased value for our shareholders."

The company expects to make capital investments of approximately $117 million in 2007. The Company's ongoing effective tax rate for 2007 is estimated to be 32%.

NOTES:

(1) Ongoing operations, profit from ongoing operations, net income from ongoing operations, EBIT and EBITDA, wherever used herein, are non-GAAP financial measures. The ongoing operations include Paper Technologies and Ventures, the Aqualon Group and FiberVisions. Results from ongoing operations exclude impairment charges for certain facilities within these businesses, which will have no further operating impact, charges related to divested businesses, litigation against and settlements with the Company's insurance carriers, executive retirement benefits, and legal accruals and settlements. It also excludes the impact of the prepayment and refinancing of long-term debt. Please refer to Tables 2, 3, 4, 5, 6 and 7 for the reconciliation of reported to ongoing operations for all periods presented.

EBIT is calculated as net income (loss) before income taxes plus interest and debt expense. EBITDA is calculated as net income (loss) before income taxes plus interest and debt expense, depreciation and amortization, net of amortization of debt issuance costs.

EBIT and EBITDA are measures commonly used by the capital markets to value enterprises. Interest, taxes, depreciation and amortization can vary significantly between companies due in part to differences in accounting policies, tax strategies, levels of indebtedness and interest rates. Excluding these items provides insight into the underlying results of operations and facilitates comparisons between Hercules and other companies. In addition, EBITDA is considered a reasonable approximation of gross cash flow and is one of the measures used for determining debt covenant compliance. Management believes that EBIT and EBITDA information is useful to investors for these reasons. This measurement is not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance.

(2) These accruals and settlements relate to non-asbestos litigation matters.

(3) Other primarily includes gains and losses related to formerly divested businesses and other costs.

(4) Adjustment items have been tax affected at the U.S. federal statutory tax rate of 35% for 2006 and 2005, except the loss on the sale of FiberVisions, which had no corresponding tax benefit as valuation allowances were established on the capital loss. Additionally, the related earnings per share impact is based upon diluted shares totaling 113.1 million and 110.1 million for the three months ended December 31, 2006 and 2005, respectively, and 111.3 million and 110.4 million for the Twelve Months ended December 31, 2006 and 2005, respectively.
