Deal Q&A

1.              Why is Zep Inc. selling itself? Why now?

·                  After careful consideration, the Board determined that this transaction with New Mountain Capital is in the best interest of Zep Inc. stockholders.

·                  This transaction delivers immediate and substantial cash value to Zep Inc. stockholders, at a 23% premium to Zep Inc.’s 90-day volume weighted average stock price for the period ended April 7, 2015.

3.              Who approached whom?  When did discussions begin?

6.              What happens if a third party emerges with a higher bid? Is there a “go shop”?

·                  Today’s announcement comes after a thorough review of strategic opportunities conducted during the past year to enhance shareholder value — Zep Inc.’s board of directors unanimously approved the merger agreement and recommends that the Company’s stockholders vote in favor of the transaction.

·                  As you may have seen in the press release, the definitive agreement contains a “go-shop” provision under which Zep Inc. has the right to solicit alternative proposals from third parties during the next 30 calendar days on customary terms and conditions for transactions of this nature.

·                  There can be no assurances that this process will result in any alternative transaction and we are not going to speculate on the process today.

10.       Have you spoken with your stockholders? What has GAMCO said? Are you confident that there is enough support for this transaction to be completed?

·                  As you would expect, we are in dialogue with our large stockholders, although it would not be appropriate for us to comment on specific conversations.

·                  Zep Inc.’s board of directors unanimously approved the merger agreement and recommends that the Company’s stockholders vote in favor of the transaction.

·                  This transaction provides Zep Inc. stockholders with immediate and substantial cash value at a 23% premium to Zep Inc.’s 90-day volume weighted average stock price for the period ended April 7, 2015.
