Hillshire Employee Talking Points

• By now you have heard the exciting news that we’ve entered into an agreement to acquire Pinnacle Foods. You should have received the note from Sean, along with the press release issued earlier this morning.

• This is an exciting opportunity for Hillshire Brands and we truly believe that Pinnacle represents an ideal partner for us.

• As you may know, they are a well-respected company with a robust portfolio of leading brands including Birds Eye^®, Duncan Hines^®, Vlasic^®, and Wish-Bone^®, among others.

• In addition to their iconic brands, Pinnacle also shares our passion for developing innovative products, as well as our focus on maintaining a lean and efficient operating structure and close ties with customers.

• The New Hillshire will have leading brands and strong positions in key frozen, refrigerated and center store grocery categories.

• Together, we’ll have increased scale and a more diversified portfolio.

• These advantages will enable us to continue investing in our brands – driving further growth through innovation and product extensions – and delivering outstanding benefits to our consumers, customers and shareholders.

• The New Hillshire will be headquartered in Chicago and Sean will continue to be our president and CEO.

• Importantly, today’s news is just the first step in the process. While we expect the transaction to close by September 2014, it is subject to regulatory and shareholder approvals and other customary closing conditions.

• Over the coming weeks and months, we will be working with Pinnacle to develop an integration plan.

• We’ve already identified the integration team leader for Hillshire and Tom Hayes, our Chief Supply Chain Officer, will be heading those efforts from our side.

• Tom and the rest of the integration team will work with their relevant Pinnacle counterparts to facilitate a smooth combination of our organizations once the transaction closes.

• We are excited to bring together talented individuals from both sides to create a strong combined company.

• However, until the transaction closes, Hillshire and Pinnacle will continue to operate as independent companies. This means it is business as usual here, and that means closing the year strong.

• I can assure you, we’ll do our best to keep you informed as we move through the process.

• This is an incredibly exciting time at Hillshire, and we believe this transaction presents a compelling opportunity.

• As always, thank you for your continued support and commitment.

Q&A

1. How will this transaction impact current Hillshire Brands employees? I heard a mention of $140 million in expected cost synergies, does that mean there will be changes at Hillshire Brands?

• As a result of this transaction, Hillshire employees will have the opportunity to be a part of a larger organization that is a leader in key grocery categories.

• We anticipate that the combined company will present even greater career opportunities for employees.

• As we move through the integration process, we are excited to bring together talented individuals across both our organizations to create a strong combined company.

• We expect to move quickly to develop integration plans and will have more information to share in the weeks and months to come.

3. What should I be telling customers/suppliers?

• It is important to note that this announcement is just the first step in the process and we will continue to operate as independent companies until the close of the transaction, which is expected by September 2014.

4. What happens between now and the close of the transaction?

• This announcement is just the first step in the process and we need to obtain the required regulatory and shareholder approvals and other customary closing conditions. The transaction is expected to close by September 2014.

5. Are there any plans for Hillshire Brands facility closures associated with this deal?

• We will provide any relevant updates as we move through the integration process.

6. What should I do if I am contacted by the media or other third parties?
