UPDATE: DuPont Issues Statement Related to Trian Letter

DuPont issued the following statement in response to Trian Fund Management, L.P: Our board of directors and management team have taken firm action over several years that has delivered 220 percent total shareholder return since year-end 2008, compared to 144 percent for the S&P 500 during the same period, by aggressively deploying our leading science across the company, strengthening and fine-tuning our portfolio, and through disciplined capital allocation. The board and management team remain committed to executing on our strategic plan to drive growth and profitability. The recently announced first phase of our redesign initiative to drive down costs by $1 billion and embed greater efficiencies, together with the separation of Performance Chemicals and our $5 billion share repurchase program, reflect our board and management's commitment to enhance value for all DuPont shareholders. DuPont welcomes open communications with shareholders and values input toward our common goal of enhancing shareholder value. We speak and meet with shareholders frequently, and while it is our policy not to comment on discussions with specific shareholders, we have had a constructive dialogue with Trian. DuPont
