MERGER

Customer Call Script

I am happy to share with you some very exciting news.

Office Depot and OfficeMax have agreed to a merger of equals – with the goal of creating a stronger, more efficient global provider of office products, services, and solutions.

We believe that our proposed merger will greatly benefit you.

The combined company will have an even broader global footprint, provide an enhanced selection of products and services, and deliver efficiencies and synergies – all of which we can share with you.

By joining with OfficeMax, we believe that we will be able to offer expanded opportunities for our valued customers while presenting a more dynamic enterprise to the marketplace.

At Office Depot, we are committed to ensuring that you do not experience any disruption during this time. We also want to provide you with the comfort that we intend to fully honor the terms and conditions of our customer agreements, both prior to and after this transactions closes.

We currently expect the transaction to close by the end of 2013. Of course, that depends on a series of approvals that need to take place first, including approval by the Federal Trade Commission (FTC).

FOR MAJOR CUSTOMERS:

It is not unusual for the FTC, as part of their examination, to contact customers, and solicit views with respect to the transaction. If you do hear from the FTC, we would appreciate it if you would let us know. It will inform us that the process is moving along in an expeditious manner.

IF the customer asks how you would like them to respond to any questions asked by the FTC, answer that they are completely free to respond in any way they feel appropriate and that you are letting them know that the FTC might contact them.

IF customers express anger about the fact that they need to respond to the FTC’s questions, stress that they are among your most important customers and that Office Depot is under a legal obligation to provide their contact details to the FTC.

Until all necessary approvals are received, both Office Depot and OfficeMax will continue to operate as separate and competing companies.

I am confident that, by merging with OfficeMax, Office Depot will be not only a stronger competitor within the industry, but a more attractive partner to you and your organization.

If you have any questions, please feel free to contact me directly. You can also find additional information on our website, at www.officedepot.com.

Thank you again for your continued support. We greatly value your business.
