Late Stage Portfolio Targeting Proven Markets Bendamustine RTD Bendamustine RTD Low-volume, shorter infusion time Ryanodex (dantrolene): Malignant Hyperthermia Ryanodex: Exertional Heat Stroke RTU bivalirudin Pemetrexed Argatroban Tentative Approval 7/2/14 Launched 8/29/14 1 Source: publicly filed reports with the SEC, independent market research and management’s estimates

Bendamustine RTD Improved formulation of Treanda1 for CLL2 & NHL3 Ready-to-dilute concentrated liquid of cytotoxic API Same volume diluent, same infusion time 7/2/14 received tentative approval for NHL Commercial launch Window - 2015 through early 2016 Longevity post-launch: 1 issued patent & 4 filed Expiry expected 2031-33 Patent litigation – ahead of ANDA litigation Plaintiff filed Motion to dismiss ‘524 infringement case Teva initiated new ‘270 infringement case in August 1 Treanda® (bendamustine HCl) (Cephalon, Inc., a wholly-owned subsidiary of Teva Pharmaceutical Industries Ltd.) 2 CLL: chronic lymphocytic leukemia 3 NHL: indolent B-cell non-Hodgkin lymphoma

Lower-volume Shorter Infusion Time Bendamustine RTD Highlights Patient Benefit Less chair time: 30 or 60 minutes reduced to 10 minutes Less volume and the issues related to 50ml vs. 500mL Longer Shelf Life (less degradation products) Eliminates the need for exposure to DMA Nurse Less nursing time required Medical/Patient 90% reduction in NaCl – renal suppressed population Economic Benefit Additional patients treated in the cancer clinic due to shorter infusion time Anticipated to sell for slightly less than innovator

Lower-volume Shorter Infusion Time Bendamustine RTD Same product as bendamustine RTD Dilute in 50mL admixture rather than in 500mL Potential to convert market based on improved product attributes Received Orphan drug designation for CLL and NHL July 2, 2014 May afford 7 years exclusivity on approval Depomed Gralise Court Decision One issued patent with expiration date in June 2031

Lower-volume Shorter Infusion Time Bendamustine RTD Randomized, blinded clinical trial Phase I PK/Safety Study Enrollment complete, data results anticipated by year-end

No change to SOC for MH treatment in over 30 years Can be fatal if untreated Old product typically requires 720 ml (12 vials) Eagle optimized formulation reduces to 5ml (1 vial) Breakthrough change Expected to take over market Launched Ryanodex 8/29/14 Protected market position 3 patents issued + 1 filed Orphan drug designation for MH EU regulatory submission expected to be filed by 2015 Ryanodex (dantrolene) for Malignant Hyperthermia (MH) 1 Retrospective study conducted by the Malignant Hyperthermia Association of the United States (MHAUS)

Ryanodex US Commercial Landscape Branded dantrolene sales for MH ~$20M in 2013 Ryanodex pricing expands addressable market Ryanodex advantages support premium pricing Faster administration Reduced volume Significant reduction of Mannitol (diuretic) All 6,000 US hospitals required to stock dantrolene MHAUS1 recommends a minimum of 36 vials of old product vs. 3 vials of Ryanodex Market unlikely to revert to old 720ml formulation Eagle is commercializing (without partnering) Established small contract sales Commercial infrastructure in-place 1 MHAUS: Malignant Hyperthermia Association of the United States

Why Dantrolene? MH Exertional Heat Stroke Ecstasy Overdose Duchenne Europe ROW Initial indication: Malignant Hyperthermia Larger markets + Unmet needs Further opportunity for all indications Malignant Hyperthermia is just the tip of the iceberg Rhabdomyolysis

Ryanodex Label Expansion Opportunity Exertional Heat Stroke (EHS) Est. 23,000-38,000 cases/year1 A leading cause of student athlete death (US) & non-combat military deaths Similarities to MH Potential for Ryanodex to be first to market for EHS Orphan drug designation for EHS Potential for 7-10 year life cycle w/o competition Market estimated at $150M 1 Estimate based on 2010 population projections

Bivalirudin: $550M – Approximate Brand Sales Enhanced RTU version of the anticoagulant Angiomax Completed three registration batches for NDA submission 2 patents issued; third patent filed 1Q:14 NDA submission targeted for Q2:15 US launch planned as early as Q1:16
