ONCURE HOLDINGS, INC.

FORT MYERS, FL, June 24, 2013 — Radiation Therapy Services Holdings, Inc. (“Radiation Therapy” or “the Company”), a leading operator of radiation therapy centers, announced today that its wholly owned subsidiary, Radiation Therapy Services, Inc. (“RTSI”), entered into a “stalking horse” investment agreement to acquire OnCure Holdings, Inc. (together with its subsidiaries, “OnCure”) upon effectiveness of its plan of reorganization under Chapter 11 of the U.S. Bankruptcy Code for approximately $125 million, including $42.5 million in cash (plus covering certain expenses and subject to working capital adjustments) and up to $82.5 million in assumed debt. In addition, OnCure’s secured noteholders have executed a restructuring support agreement outlining their commitment to support the transaction.

Completion of the transaction, which is expected to occur prior to the end of October 2013, remains subject to competing offers, approval by the United States Bankruptcy Court, and customary closing conditions.

Dr. Daniel Dosoretz, President and Chief Executive Officer of Radiation Therapy Services said, “We are pleased to have entered into an agreement with OnCure to acquire the business. The addition of OnCure, including its partnerships with teams of many of the most highly respected physicians in the industry, will broaden and deepen our ability to provide world-class treatment to patients and offer our integrated cancer care model in key markets across the United States. We are excited by the prospect of working with OnCure’s physician partners to provide technically advanced and successful cancer treatment to their patients and plan to work with the company and its stakeholders to conclude its reorganization and our acquisition expeditiously. The acquisition of OnCure would be a significant addition to our business creating additional prospects for growth.”
