American Radiology Services Regulatory Update

Deficit Reduction Act of 2005 Through a series of cost cutting measures and new revenue initiatives, ARS has mitigated the impact of DRA Impact of DRA fully reflected in 2007 results Technical component reimbursement capped at lesser of Medicare Part B and Hospital Outpatient Prospective Payment System (HOPPS) rate 25% 50% reduction in reimbursement for scan of contiguous body parts Effect of rate cuts: ~ 10% reduction in MRI reimbursement rate ~ 7% reduction in CT reimbursement rate ~ 26% reduction in PET reimbursement rate 18

Recent Pressure on Self Referral National Pressure Study published in 2007, links higher rates of imaging with self-referring physicians Use imaging 1.1 2.3x times more often Industry lobbying groups creating focus on impact of self referrals Likely to lead to restrictions Physicians are already prohibited from self-profiting referrals As a result, non-radiologists have begun shutting down their self-referred imaging businesses Local Pressure & Recent Developments Maryland self-referral laws similar to Federal Maryland already prohibited referrals to physician-owned equipment In 2006, the Maryland Board of Physicians issued a ruling supporting this enforcement A 2007 appeal upheld the existing MD laws (ruling has been re-appealed) This ruling, combined with the ONI relationship, will make ARS the preferred partner of specialist practices 19

Opportunity to Grow Orthopedic Scan Volume Recent legislative and regulatory changes have provided ARS with a significant opportunity to take market share from smaller imaging practices Rationale Potential Upside Opportunity to gain volume fallout DRA rate cut MD Stark Law enforcement Added CMS scrutiny of selfreferral Opportunity to offer incremental services to orthopedic practices Leverage sales and marketing expertise to promote dedicated referral relationships There are ~20 large orthopedic groups in the MD region that operate their own imaging equipment These sites perform approximately 30,000 40,000 scans per year These practices have fewer and less sophisticated modalities than ARS sites 20

Regulatory Issues Today Lobbyists fighting to prevent further cuts AQI Federal Access to Medical Imaging Coalition (AMIC) State Awaiting action on court case appeal Summer study session on self-referral law Current Senate Proposal Excludes any new cuts Accreditation requirements included 21

American Radiology Services Growth Opportunities Bob Carfagno, President & CEO

Growth Strategy With a strong brand name and scalable initiatives, the ARS platform is well positioned to drive margin improvement at a regional or national level Transition to Digital Mammography Improved patient care, productivity and increased billing rate To be completed in 2008 New RIS/PACS Modern technology will enhance efficiency and improve patient care Being evaluated with CML Expand Teleradiology Business Organic Growth Program High growth potential, low CapEx requirement Enhanced penetration in the Orthopedic market Establishment of dedicated women s imaging centers Expanded marketing of alternative procedures with high tech equipment Acquisition and JVs Growth through acquisitions and partnerships 23

Projected Impact of Digital Mammography ARS is in the process of rolling out digital mammography in 14 clinics and transitioning its current volume at a favorable reimbursement rate Faster throughput will help reduce existing backlog Demand for superior technology will increase scan volumes Improved customer satisfaction, especially among women, may encourage greater brand loyalty 24

Increased Focus on Women-Specific Care One of the Company s largest facilities doubled revenue and increased EBITDA margins in the first three full years after expanded service offering Leverage existing infrastructure Opportunity to significantly increase volumes Management has identified three additional sites that could particularly benefit from women s centers Opening additional women s centers could capitalize on excess demand at a number of ARS office locations, while growing overall volumes and increasing patient satisfaction Maximizes referrals across specialists and modalities 25

ONI Strategic Relationship An exclusive distribution agreement with ONI Medical will supply ARS with next generation MRI systems and drive referrals ARS has the exclusive right to distribute ONI extremity MRI systems in Maryland and Delaware Systems can increase efficiency by 20-25% ONI systems keep the majority of a patient s entire body outside the imaging magnet Increases comfort and decreases involuntary movement Compact and less expensive than traditional MRIs Still exceeds current ACR guidelines for knee MRI tests Well suited for small outpatient centers, especially orthopedic practices Opportunity to increase referrals from orthopedic specialists ARS can even enter orthopedic practices to perform imaging services 26

Significant Acquisition Opportunities Medical imaging expenditures in the U.S. are estimated at US$100 billion and expected to grow to US$110 billion in 2009 Out-patient medical imaging market represents approx. US$45 billion of total expenditures NE U.S. comprises US$10 billion of out-patient market U.S. medical imaging market is highly fragmented and undercapitalized, primarily consisting of small group practices and regional providers Approx. 6,000 out-patient diagnostic testing facilities DRA is driving consolidation of "mom and pop" imaging operators ARS has a strong, scaleable platform to pursue acquisition opportunities NE U.S. presents an attractive market into which to expand Strong demand for medical imaging Favorable demographics (dense population) 6 of the 10 wealthiest U.S. states by income 27
