Emergency Medical Services Agrees to Acquire MedicWest Ambulance
in Las Vegas, Nevada

Greenwood Village, CO—(June 11, 2007)—Emergency Medical Services Corporation (NYSE: EMS) (the “Company”) today announced that it has entered into a definitive stock purchase agreement to acquire MedicWest Ambulance, based in North Las Vegas, Nevada. MedicWest and American Medical Response (AMR) are the franchised emergency ambulance transportation services providers in the greater Las Vegas market. Both companies also provide non-emergency ambulance services.

William A. Sanger, EMSC Chairman and Chief Executive Officer, said, “This acquisition is consistent with our strategy to expand our market share in contiguous service areas in order to enhance economies of scale. We continue to deliver on our business plan of supplemental growth through carefully planned acquisitions that complement our current markets, and expansion into new markets.”

Upon completion of the transaction, MedicWest will be owned by Nevada Red Rock Ambulance, Inc., a wholly-owned subsidiary of American Medical Response. AMR and MedicWest will continue to operate under their respective brands in the Las Vegas market.

John Wilson, Executive Partner of MedicWest said, “We are very pleased with the opportunities that come from our new affiliation with AMR. This change in ownership will give the Las Vegas community all the strength of a national company, combined with local management teams focused on exceptional patient care and service through the AMR and MedicWest brands.”

Bob Ramsey, Chairman of MedicWest and CEO of the parent company, Starwest, said, “The sale offers a unique opportunity to deliver high performance ambulance service with some of the finest EMS personnel in the nation.”

The agreement to purchase MedicWest was entered into on June 11, 2007. The transaction is expected to close in 30-60 days, subject to local regulatory approvals, including in Las Vegas, North Las Vegas and Clark County, and other customary closing conditions. The Company estimates that MedicWest will contribute annual revenue of approximately $24 million and 60,000 transports.
