The email below was sent to certain employees of E. I. du Pont de Nemours and Company ("DuPont") on April 6, 2015:

An all-employee message from Ellen Kullman, Chair and CEO of DuPont.

Dear Colleagues,

Today we are filing with the Securities and Exchange Commission a new investor presentation [hyperlink] that tells our story of progress and demonstrates the strength of the next generation DuPont.  This presentation will be used in upcoming meetings with shareholders and posted on the investor page of DuPont.com, as well as our special website, www.dupontdelivers.com.

Importantly, this presentation shines a bright light on what we within the Company are experiencing first-hand: our momentum is building, and the next generation DuPont is emerging and already delivering more stable growth and higher value. Our innovation platform and cost discipline are driving margin growth and increased earnings, and our ongoing, post-spin business will continue on that path. The ongoing business already has delivered 6% segment sales growth(i) and 19% adjusted operating EPS compound annual growth rate since December 31, 2008.(ii)

I am very proud of the many achievements that have brought us to this point. Among them:

·                  Transforming our portfolio to focus on large, attractive opportunities where our science can deliver the greatest value;

·                  Leveraging our market-driven innovation platform to deliver value-added customer solutions and enhance our competitive position;

·                  Improving productivity and reducing costs, while creating a more streamlined and agile organization—scaled for the next generation DuPont;

·                  Extending our global presence, especially in developing markets; and

·                  Continuing to deliver superior shareholder returns, including significantly increasing our dividend.

This record of accomplishment reflects your talent, dedication and hard work and underscores that each of us has a great deal to contribute as we work together to build the next great era of DuPont.  I encourage you to review the presentation, which also describes the opportunity we see ahead in each of our strategic focus areas. Our vision and strategy for the next generation DuPont and the key progress we are making will continue to be an active theme of our internal dialogue throughout 2015.

The new shareholder presentation also outlines in detail why our Board unanimously concluded that Trian’s agenda to break up and add excessive debt to our Company is not in the best interests of DuPont shareholders, and why having a Trian representative on our Board is a threat to the progress we are making and to the value of our shareholders’ investments in our Company.  Trian’s nominees are committed to their own high-risk, value-destructive agenda.  They offer no incremental value to DuPont’s outstanding Board of Directors and would significantly reduce or eliminate essential experience and skill sets that your Board currently possesses.  The presentation also explains in greater depth how Trian’s value-destructive agenda to break up and add excessive debt to our Company would harm our innovation platform, diminish our global reach, and increase costs—resulting in a less competitive DuPont.

For these reasons, I want to remind you that if you are a shareholder and have received proxy materials, please vote on the WHITE proxy card “FOR” all of DuPont’s director nominees for each account through which you own DuPont stock. It is also very important that you not return any “gold” proxy cards at all, even to withhold your vote.  If you return a “gold” proxy card, it will revoke any previous WHITE proxy card that you may have submitted in support of your DuPont Board nominees. It is important to note that, depending on how you hold your shares, the Trian card may be a very pale gold and may not be easy to distinguish from our WHITE card. However, the word “gold” will appear on the Trian proxy card. Therefore, please read any materials you receive carefully, as your vote on the WHITE proxy card is important. To prevent error, it is best to discard any proxy materials you receive from Trian.

Remember: every vote is important, no matter how many or how few shares you own, and you do not need to wait for the annual meeting to vote. If you have any questions about the voting process, please contact the firm assisting us on this matter: Innisfree M&A Incorporated at (877) 750-9501 (toll free) or (412) 232-3651.

I know we are all beginning to feel the excitement as we look to the future. The results we have delivered to date—and the potential we see ahead—reinforce the importance of supporting DuPont’s exceptionally well-qualified Board members, so that we can continue executing our successful strategy.

I will continue to keep you up to date on our latest communications with shareholders.  In the meantime, thank you for your continued focus and commitment to deliver for all of the many stakeholders who count on DuPont.

Ellen
