ENDO HEALTH SOLUTIONS INC. ANNOUNCED

AS NEW NAME FOR ENDO PHARMACEUTICALS HOLDINGS INC.

CHADDS FORD, Pa., May 23, 2012 – Shareholders of Endo Pharmaceuticals Holdings Inc. (NASDAQ: ENDP) voted today at its annual shareholders meeting to approve changing the company’s name to Endo Health Solutions Inc.

The name change is in conjunction with the launch of Endo’s new corporate identity and more accurately reflects the company’s new business model. Endo Health Solutions has aggregated four operating businesses into one enterprise aimed at delivering fully-integrated, end-to-end solutions principally in pain management and urology for the benefit of providers, payers and patients.

Endo’s vision is to approach therapeutic areas and disease states as pathways, and to identify, develop and incorporate medical interventions beyond the traditional chemical and biological treatments.

“This important decision by our shareholders marks a milestone in our company’s history,” said Dave Holveck, President and Chief Executive Officer, “and reinforces our position in the market as a leading provider of health solutions, merging healthcare information and a broader array of innovative treatment options that can ultimately lead to improved health outcomes for patients.”
