RR Donnelley Forms Strategic Alliance With IntraLinks to Offer Virtual Data Rooms to Thousands of Clients Worldwide

NEW YORK, NY and CHICAGO, IL
October 15, 2004

R.R. Donnelley & Sons Company (NYSE: RRD) is forming a strategic alliance with IntraLinks, the leading provider of virtual data rooms to the mergers and acquisitions (M&A) industry, to help RR Donnelley clients take M&A due diligence online. The alliance between RR Donnelley and IntraLinks represents an important evolution of an existing relationship through which RR Donnelley's financial printing division offers the IntraLinks Virtual Data Room to its global client base of more than 3,000 law firms, corporations, banks, private equity firms and other businesses. IntraLinks provides online services for the secure exchange of confidential information throughout the financial services industry.

The agreement formalizes RR Donnelley's position as the first financial printer to offer the IntraLinks virtual data room solution to its clients. The service complements RR Donnelley's comprehensive suite of services, which includes content creation and management, EDGAR and worldwide regulatory filing, translation, print production, and distribution of regulatory and compliance documents.

"The future of M&A due diligence is online," said Terry Trayvick, president of Financial Print Solutions at RR Donnelley. "Responding to client needs with unparalleled solutions has enabled us to be named the number one printer four years in a row by FORTUNE magazine. Our partnership with IntraLinks allows us to provide to our clients the best virtual data room on the market and to meet the full scope of our clients' transaction management needs."

"By partnering with RR Donnelley, we can bring the benefits of virtual data rooms to the global M&A community faster," said Patrick Wack, president and CEO of IntraLinks. "We are excited to continue this key strategic partnership. Like IntraLinks, RR Donnelley recognizes the importance of trust and service in its client relationships, and we look forward to working with them to expand our presence in the market."

Sellers in M&A transactions traditionally set up physical rooms filled with confidential documents for due diligence. Buyers travel to these rooms to review the information for days or weeks at a time. Using virtual data rooms, deal-related documents are uploaded to a secure website where bidders can access them anytime, anywhere through a Web browser.

Virtual data rooms cut an average of 30 days off M&A due diligence time by allowing an unlimited number of bidder teams to access deal information simultaneously. In most cases with physical data rooms, only one bidder team can enter the room at a time.

During the course of a transaction, RR Donnelley plays a critical role by ensuring documents reach regulators and investors in an efficient and timely manner.
