CONTENTS ARE CONFIDENTIAL ORBITAL THERAPY, LLC Dedicated, self-shielded device for breast radiotherapy

Problem We are overdosing the patient and treating healthy tissue. Conventional equipment ONLY allows for 2 beam access when treating breast, limiting the use of any advanced radiotherapy protocols and techniques such as SRS, IMRT

COMPANY CONFIDENTIAL Solution Cranial Extra-cranial Reproduce what is already being done for most other cancers. Conventional equipment currently used to deliver advanced treatment to other organs but not breast. The limiting factor is the geometric rotation of the treatment machine.

Prone VS Supine Key Benefits of Prone: Increased separation of breast from other organs Reduced organ/patient motion due to breathing Reduced dose to lung & heart

No Clinical Trials for FDA 510k & CE MammoKnife TM 6MV accelerator Multileaf Collimator Rotating Couch Anti-Reflective Beam Stop Integrated Shielding Cone-beam CT Image of breast in prone position COMPANY CONFIDENTIAL

Self Shielded - VS - Bunker Key Benefits of Self-Shielded: Lower patient body dose of unwanted radiation Reduced cost of install – bunker can range from $1-5M Reduced time of install Simplified relocation – no tear down $2M – $2.5M machine $0 – $100K room $1M – $5M room $1M – $5M room + $2.5M - $4M machine

COMPANY CONFIDENTIAL Prototype Ready – Beam ON! Industrial Design Operator in room with patient Only breast in the “bunker” CAD model Drum contains 6MV accelerator, MLC Anti-reflective beam-stop Proof-of-concept Prototype built Beam turned on – no additional shielding added, operator in the same room

RT procedure volume growing at 7% per year* Breast cancer RT increased from 20% to 24% from 2007 to 2009* External beam accounts for 94% of all treatments* $4B radiotherapy market size ($1B breast) centers in US & EU A 5% market share = 50 units = $125M in sales Large Market Opportunity *Source: IMV Reports 2008 & 2010
