DuPont Conducted a Comprehensive Evaluation of Trian’s Proposals Retained two independent financial advisors and leading third party consultants to evaluate proposals and Trian’s assumptions Incorporated feedback from individual business unit leaders, suppliers, customers and other key stakeholders Collected observations and feedback regarding Trian’s proposals from shareholders, research analysts, and third party sources Discussed the potential implications to our ongoing funding access and credit investors directly with Moody’s, S&P, and Fitch Trian Has Criticized DuPont’s Lack of Engagement Despite More Than 20 Meetings With DuPont’s Lead Director / Senior Management More than half of the engagements involved our independent Lead Director Consecutive quarterly update calls to discuss earnings and ongoing developments since Trian’s investment Multiple Board meetings to discuss, analyze and vote on Trian’s proposals “We were very frustrated by the lack of interaction after we had presented our White Paper to management [ ] we had never experienced a management team so reluctant to engage in a dialogue” – Trian Public Letter, 16-Sep-2014* Comprehensive Review Process The Board, Management, and Multiple Independent Advisors Unanimously Concluded Trian’s Proposal Was Not in the Best Interests of All Shareholders Trian claims that anything short of adopting its full agenda is considered unconstructive dialogue *Permission to use quotation neither sought nor obtained.

Trian’s Agenda Will Result in a Less Competitive DuPont With Increased Costs and Diminished Ability to Create Value Trian’s Plan to Breakup DuPont Would Result In Significant Destruction of Shareholder Value Substantial Upfront Impact Estimated to be $4 billion(25) Impact of significant one-time costs including debt breakage, separation charges, tax implications, and other potential additional one-time funding needs Significant Incremental Ongoing Costs Estimated to be approximately $1 billion Annually(25) Reduced infrastructure efficiency such as duplicative pre-tax corporate overhead costs, incremental pre-tax interest expense, and reduced tax planning efficiency $1 billion costs estimate does not include additional impact of strategic, business, and commercial dis-synergies Destruction of Innovation Platform Adversely impacts DuPont’s growth potential by eliminating ability to leverage fundamental multi-disciplinary science background and cross platform R&D programs to continue to develop breakthrough products Diminished Global Reach Loss of unique competitive advantage and benefits of large, global customer relationships across DuPont’s businesses Weakened Brand Reduces global brand awareness and market position which would impact pricing power with new and existing customers worldwide Disrupts Ongoing Businesses Execution Jeopardizes cross selling opportunities, market access, and employee engagement

Trian’s proposal relies on financial engineering, introducing significant risk while decreasing DuPont’s ability to: Fund growth R&D and capex Pursue important strategic opportunities React to and withstand periods of economic volatility Manage seasonal and regional cash flow requirements effectively Trian’s proposal demonstrates a lack of fundamental understanding of the unique financing needs of a global science company In its White Paper on 2/17/2015, Trian suggests adding 1.5x incremental leverage, which essentially doubles DuPont’s existing financial debt Trian’s proposal also ignores pension and other obligations which must be included within credit ratings metrics – if we added 1.5x of incremental leverage, our Net Debt / EBITDA would rise to approximately 3.5x, adversely impacting our credit ratings(26) Excessive debt impairs liquidity which threatens consistent access to capital markets and diminishes ability to fund seasonal and regional businesses efficiently Our Strong Balance Sheet enables us to execute on our strategy Prudent and efficient capital structure has allowed DuPont to pay consecutive quarterly dividends since 1904, including through the most recent financial crisis Excellent capital markets access has supported short-term and strategic business needs Trian’s Plan to Add Debt Would Increase Risk and Jeopardize DuPont’s Financial Flexibility Trian’s Agenda Would Significantly Limit Our Ability To Continue to Execute Our Strategy

“Mr. Peltz’s spin-off plan [ ] would leave the remaining Company [ ] with more expensive financing costs, poorer access to the debt and commercial paper markets, and little cushion for the next and inevitable downturn.” - Gimme Credit, 4 February 2015* “Value destruction from a complete split could be about $20B from lost working capital efficiencies, high taxes from asset sale gains, and additional overhead from splitting businesses, among other factors. We maintain our view that a majority of investors will side with DD as Mr. Gallogly did, having previously had discussions with Trian.” - Wells Fargo, 27 March 2015* “Moody's views activist investor Trian Partners' proposed strategic and operating initiatives that call for a breakup of E.I. du Pont de Nemours (DuPont, A2 stable) as being credit negative [ ] A breakup of DuPont would leave two much smaller entities and each one individually would likely not be able to support DuPont's current credit profile. Neither entity would have the scale and business diversity of DuPont today. Both would exhibit greater volatility in earnings and cash flows.” - Moody’s, 26 September 2014* “DuPont’s businesses are good free cash flow generating entities as the company is configured currently. There are earnings risks near term due to the weakness in the Euro [ ] However, we think that these risks are probably more than offset by the benefits of the progressive rationalization of DuPont’s business model to increasing return and free cash flow generation.” - J.P.

Trian is responsible for all recent value creation at DuPont DuPont’s current Board and management team have a well-documented record of taking decisive action since 2009 and continue to execute on a transformative strategy that has delivered clear results, many of which were initiated or executed long before Trian’s investment Trian’s time periods are the right ones to measure DuPont’s performance Trian selectively uses 28 different time periods in their February 17, 2015 White Paper to attack DuPont’s current Board and management – 13 of which occur before current management began DuPont has $2 – 4B in excess corporate costs DuPont does not even have $4B in total corporate costs (Functional overhead, including corporate costs, were approximately $2.8 billion in 2014) Trian uses incorrect extrapolations based on the sale of one division to arrive at unrealistic estimates DuPont has already identified $1.3B of specific run-rate cost reductions with the “Fresh Start” program and is committed to continuing the evaluation of additional savings opportunities EPS decline over the last 3 years Trian’s misleading analysis relies on an arbitrary year self-servingly selected by Trian and includes data from businesses that are no longer or will no longer be part of the portfolio Adjusted operating EPS from ongoing businesses had a 16% CAGR over the last 3 years (2011 – 2014)(34) Capital returned to shareholders below peers DuPont has returned approximately $14B under current management representing 5.2% of its average market cap and significantly outperforming the S&P 500, S&P Chemicals and S&P Materials(4,5,12,18) Agriculture R&D spend has yielded negative results DuPont Agriculture adjusted segment EBITDA margins expanded >400 basis points and sales grew at a 10% CAGR, leading all major competitors while significantly increasing NA corn seed and soybean share(2,35) Focused investments in commercial, production and R&D are delivering: new products introduced in the last four years accounted for >40% of 2014 Agriculture segment sales including higher value seed offerings e.g. Optimum® AQUAmax® and new chemistries with novel modes of action e.g. Rynaxypyr® Trian has a plan to drive value creation at DuPont To date, Trian’s central value creation plan has been its flawed proposal to breakup the company further – yet it continues to be selectively inconsistent when describing its position Trian’s Platform is Based on Misrepresentations and Distorted Analyses The Facts Trian’s Myths
