ANNOUNCEMENT TO DISTRIBUTORS

On Wednesday, October 28, Snyder's-Lance announced that it has signed a definitive agreement to acquire Diamond Foods, Inc. an industry leader in snack foods with five brands in Kettle Brand^® potato chips, KETTLE® Chips, Pop Secret^® popcorn, Emerald^® snack nuts, and Diamond of California^® culinary nuts.

Diamond Foods is an industry leading company with exceptional brands, and we're excited to bring together Diamond Foods with our talented and creative Snyder's-Lance team.

Diamond has excelled in delivering exceptional product quality for many years, with innovation across their entire product portfolio. There are a number of current products and new product ideas that will work perfectly alongside our Snyder's-Lance brands. We plan to take full advantage of our established Direct Store Delivery (DSD) and direct sales network as well as the expertise Diamond brings from their sales team to drive better top line than either company could achieve alone. Each Diamond brand brings unique capabilities that will strengthen Snyder’s-Lance’s strategic plans while increasing annual top line revenue. The transaction will expand our business in the better-for-you snack category and increase our presence in the natural food channel as well.

Given the size of this acquisition, the next step will be for the Federal Trade Commission (FTC) to conduct an expected and customary review. The transaction also requires shareholder approval by both companies. This will take some months to complete. During this time and until the acquisition is complete, Snyder's-Lance and Diamond Foods will continue operate independently with no planning or other collaborative communication. In other words, during this review it will be “business as usual”. Certain Diamond Foods products will continue as Snyder's-Lance “partner brands”.

Once completed, we will begin to work on the details of planning integration for the two companies.

These are very exciting times for Snyder's-Lance, as we continue on our journey to excel by proving that “Snacking Is Our Passion”!

FREQUENTLY ASKED QUESTIONS (F.A.Q.)

What does today’s announcement mean?

· Snyder’s-Lance has signed an agreement to fully acquire Diamond Foods, Inc., including Kettle Brand^® potato chips, Pop Secret® popcorn, Emerald® snack nuts, and Diamond of California® culinary nuts. When completed, these brands will be core brands of Snyder's-Lance just like our other largest brands.

Why does Snyder's-Lance want to purchase Diamond Foods?

· Diamond Foods is an industry leader in snack foods with category leading iconic brands in Kettle Brand^® potato chips, Pop Secret^® popcorn, Emerald^® snack nuts, and Diamond of California^® culinary nuts. Combining Snyder's-Lance and Diamond Foods creates a best-in-class branded snack food company, with popular brands in several major categories.

What does this transaction mean for customers/partners?

· Until the FTC review is complete, there will be no changes for Customers, Suppliers or other partners.

What happens next?

· The acquisition of Diamond Foods will require a review by the Federal Trade Commission (FTC), which will take some number of weeks. This is expected and customary. During this time, the two companies will continue to operate completely independently.

Will Diamond Foods brands continue as Snyder's-Lance partner brands?

· Yes. Until the transaction is completed, there will be no changes. Over time, we will transition the Diamond Foods brands to be core brands of Snyder's-Lance, at which time they will no longer be considered partner brands.

When is the acquisition expected to be completed?

· The acquisition is expected to be completed early in 2016.

When will the integration process start? How do you plan to integrate the two companies?

· Details of an integration plan have not yet been created. Planning for such a large integration will require time and a great deal of detailed planning. Since Snyder's-Lance and Diamond Foods must remain completely independent during the FTC review period, detailed plans will not be created until the transaction is complete. However, integration will be a top priority and is expected to begin soon afterwards.

What can customers expect during the integration process?

· Our plans are for Snyder's-Lance and Diamond Foods associates to work closely together to develop integration and change plans. Detailed plans will be created once the transaction is complete. In the meantime, each company will work independently with no changes to our day to day processes.

What is the difference between the “Kettle Brand®” and “Kettle® Chips” logos? Are they two different product lines?

· They are two brands for very similar product lines. “Kettle® Chips” is the company’s United Kingdom (UK) brand, while “Kettle Brand®” refers to the US brand and product line.
