DMX I-Trax,

Walgreens (NYSE:WAG)(NASDAQ:WAG) announced today that Putter Acquisition Sub, Inc., its wholly owned subsidiary, has successfully completed its tender offers for all of the outstanding shares of common stock and preferred stock of I-trax, Inc. (AMEX: DMX). Based on preliminary information from the depositary for the offer, as of the expiration of the offer at 12:00 midnight, New York City time, at the end of April 24, 2008, stockholders had tendered and not withdrawn 40,576,068 shares, or approximately 96.3%, of I-trax�s common stock and 214,067.33 shares, or approximately 98.6%, of I-trax�s preferred stock. In mid-March, Walgreens announced it would acquire I-trax, parent company of CHD Meridian Healthcare, LLC, an industry leading provider of integrated workplace health and productivity management solutions with clients and locations across the country. At that time, Walgreens also announced it had signed an agreement to acquire privately-held Whole Health Management, another leading operator of comprehensive worksite health and wellness centers. These worksite clinic operators, in combination with Walgreens wholly-owned subsidiary and retail healthcare clinic operator Take Care Health Systems, will form the platform for the new Walgreens Health & Wellness division. Earlier this month, the U.S. Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 applicable to Walgreens� proposed acquisition of I-trax. "We are very pleased to have successfully completed the tender offer and to be moving forward to extend our �Main and Main� strategy to include health and wellness services at the worksite," said Walgreens Chairman and CEO Jeffrey A. Rein. "The positive response we�ve received for our new Health and Wellness division from all corners of the healthcare and retail industries has been gratifying. We�re particularly pleased to be hearing from employers across the country who are excited about the prospects of working with Walgreens in new ways.� Rein added, "The acquisition of these two market leaders truly transforms Walgreens in the healthcare space and reinforces the company as a trusted consumer brand in the eyes of our customer base. We�re looking forward to working with the entrepreneurs at both I-trax and Whole Health to grow the business and benefit from our respective expertise and strengths. We have already started planning our integration activities and are confident of realizing significant additional value for our shareholders." Putter Acquisition Sub, Inc. has accepted for payment all shares of I-trax stock that were validly tendered and not withdrawn during the offering period and will make payment to the depositary for the accepted shares promptly. Following its payment for the accepted shares, Walgreens intends to effect a merger of Putter Acquisition Sub, Inc. into I-trax. In connection with the merger, all remaining I-trax stockholders who did not tender their shares in the offer (other than those, if any, properly perfecting dissenters� rights) will receive the same price per share paid in the tender offer. Following the merger, I-trax�s common stock will cease to be traded on the American Stock Exchange. Walgreens Health & Wellness division will be based in Conshohocken, Penn., and be led by Hal Rosenbluth, co-founder of Take Care Health Systems, newly-named president of this division and corporate vice president of Walgreens. The combination of I-trax and Whole Health Management will operate under the name Take Care Employer Healthcare Solutions.
