Exhibit 99.4

Dear Valued Associates,

There’s exciting news to share with you about Epiq. This morning, we announced that Epiq has agreed to be acquired by OMERS Private Equity, the private equity arm of the OMERS pension plan, and Harvest Partners, a leading middle-market private equity fund. Upon completion of the transaction, Epiq will become a privately held company and will combine with DTI, which is majority-owned by OMERS and managed by OMERS Private Equity, to create a stronger legal services technology company. The press release we issued today is attached.

This announcement marks an important milestone for Epiq, and represents the successful culmination of a comprehensive review of strategic and financial alternatives to maximize value for Epiq’s shareholders. We are confident that the transaction with OMERS Private Equity and Harvest, and the subsequent combination with DTI, will help us achieve our vision of being the world’s preferred strategic partner for complex legal matters. Since our founding, Epiq has been an industry leader and this transaction will allow us to further enhance our ability to deliver to clients around the world a more robust base of services, capabilities and expertise, serving them more effectively and holistically than ever before. Given the increasing competitive pressure in the industry, this combination will also allow us to drive the efficiencies our clients are seeking.

OMERS Private Equity invests in private equity assets on behalf of the OMERS pension plan. Harvest Partners has a 30-year history of investing in, and supporting the growth of, companies like Epiq that have leading positions in large markets with strong management teams. Both OMERS Private Equity and Harvest Partners are deeply familiar with our industry and we feel they are ideal partners for Epiq. They recognize the great potential in our company and are committed to our future.

We are excited to be partnering with DTI and to have the financial backing of two strong investors like OMERS Private Equity and Harvest Partners for many reasons. DTI is a highly successful, global legal process outsourcing (LPO) company that provides electronic discovery, litigation support and court reporting services. Together with DTI, we will create a global organization to work with regionally diverse client bases, delivering local service and segment expertise – whether it be complex, global legal discovery, class action or mass tort administration, corporate restructuring, Chapter 7 case management or more general legal services outsourcing. The comprehensive solutions of the combined DTI and Epiq organizations will position the new entity to become a full spectrum litigation support provider for law firms, corporations and government entities around the world. We are confident that the combined knowledge of our consulting and technical personnel, together with our technology, process and workflow expertise will enhance the value of all of our service offerings, and bring greater efficiencies to our clients worldwide. We look forward to the opportunity to work with the DTI team to build on existing strengths to create a stronger legal services and technology provider well positioned to address the increasingly global marketplace, and one that will provide expanded associate opportunities for cross-selling, cross-training and career growth.
