ANALYSIS OF STRATEGIC ALTERNATIVES

o     Immediate sale of Betz Dearborn to General Electric is dilutive, not only
      to earnings but to shareholder value as measured by Hercules stock price.
      Hercules currently trades at 6.5x EBITDA versus the GE transaction at 5.9x
      EBITDA, after taxes and transaction costs.

o     Significant refinancing opportunities exist today.



ANALYSIS OF STRATEGIC ALTERNATIVES

Timing of sale of Betz Dearborn inopportune

      o     Potential for significant increase in operating income/EBITDA

            >     Cost takeouts

            >     Other operating improvements

            >     Strong cash flow generator for debt paydown

      o     Low transaction multiples

            >     Historic low point

            >     Transaction multiples barely exceed market multiples

      o     Perception of being a distressed seller - only distressed sellers
            have been selling in this environment



ANALYSIS OF STRATEGIC ALTERNATIVES

o     Major shareholders are against a sale at this time

o     Costs and risks of refinancing more than outweighed by significant
      potential for substantial increase in shareholder value
