Disclaimer This presentation (the “Presentation”) includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which are based on current expectations, estimates and projections based on information currently available to management. These forward-looking statements include, among others, statements regarding growth strategies for DABRA and Pharos, including pursuing regulatory approval of additional indications including coronary artery disease, in-stent restenosis, atherectomy, and other vascular occlusions indications for DABRA and a cutaneous T-cell lymphoma indication for Pharos; the benefits of DABRA and Pharos, including the potential economic benefits to providers; statements regarding our industry and competitors; the size of our markets and patient populations; sales strategies, including increasing recurring revenues, expansion of our salesforce, raising patient and provider awareness, expanding into hospital catheterization clinics and geographically; and regarding our production capacity. Forward-looking statements are typically identified by words like “believe,” “anticipate,” “could,” “should,” “estimate,” “expect,” “intend,” “plan,” “project,” “will,” “forecast,” “budget,” “pro forma,” and similar terms. Factors that could cause the Company’s results and expectations to differ materially from those expressed in forward-looking statements include, without limitation, successfully marketing and selling DABRA; gaining market acceptance for DABRA by physicians and patients; maintaining relationships with physicians; physicians understanding how to use the Company’s products; the risk of manufacturing delays; the Company’s ability to compete successfully; the Company’s ability to attract and retain highly qualified personnel; risks related to doing business internationally; successful protecting our intellectual property; remediating the material weakness in our internal control over financial reporting and maintaining effective internal controls; the ability of providers to obtain adequate reimbursement from payors for procedures performed using our products; and general market, political, economic, and business conditions. Forward-looking statements represent our management’s beliefs and assumptions only as of our November 13, 2018 press release announcing results for the quarter ended September 30, 2018. You should read our final prospectus filed with the SEC on September 27, 2018 relating to our Registration Statement on Form S-1 (File No. 333-226191), our Quarterly Report on Form 10-Q for the quarter ended September 30, 2018 to be filed with the SEC, and our subsequent reports filed with the SEC, including the Risk Factors set forth therein, completely and with the understanding that our actual future results may be materially different from what we expect. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons why actual results could differ materially from those anticipated in the forward-looking statements, even if new information becomes available in the future.

DABRA—Excimer laser that utilizes disposable catheters for crossing total chronic occlusions (CTOs) and ablating a channel in occlusive peripheral vascular disease. DABRA is used as a tool in the treatment of peripheral artery disease (PAD), a form of peripheral vascular disease. This procedure is commonly referred to in the medical field as atherectomy, the removal of arterial plaque.1 Photochemical ablation to disintegrate plaque in the artery Tends to track the patient’s true lumen Established safety profile, effective, easy-to-use, and competitively priced No serious adverse events reported in our 2017 pivotal study or in our post-market surveillance Regulatory clearances in US and Europe PHAROS—Same laser platform as DABRA Regulatory clearances/approvals in US, Europe, China and South Korea Ra Medical Snapshot Even though the medical community refers to the procedure as atherectomy, DABRA is not currently cleared for atherectomy in the US as an indication for use. We intend to pursue an investigational device exemption, or IDE, for DABRA to achieve clearance for atherectomy as an indication for use.

Slide 5

Up to 180,000 amputations performed annually in the US as a result of PAD Disease Burden Peripheral Artery Disease Atherosclerosis of the lower extremities—most commonly in the legs Smoking, genetic predisposition, diabetes, age and obesity may increase risk Characterized by reduced blood flow to surrounding tissue If untreated can cause critical limb ischemia (CLI) resulting in ulceration, infection or gangrene and may result in limb amputation or death if left untreated Disease Overview Diagnosed by primary care physician, podiatrist or other specialist Treatment by interventional cardiologist, interventional radiologist or vascular surgeon Patient Care Only 20 to 30% of peripheral artery disease patients are actively being treated

Slide 6

Current Treatments and Limitations Non-Invasive Management Lifestyle Changes Often hard to sustain and do not treat underlying cause of disease Pharmacotherapy Generally prescribed for life and do not treat the obstruction, making them ineffective for many More aggressive treatments often required Interventional Procedures Angioplasty Trauma due to balloon inflation may cause vessel to reocclude Possible dissection May damage arterial walls Does not remove plaque Not well suited for highly calcified lesions and bifurcations Often requires stenting Stenting Subject to fractures Cannot be removed Atherectomy Other devices can damage vessel walls due to potential mechanical and thermal trauma Surgical Procedures Bypass Surgery Invasive procedure Requires general anesthesia Multi-day hospital stay Amputation Life altering procedure

Slide 7

DABRA Technology and Mechanism of Action DABRA Technology 308 nanometer excimer laser system Unique liquid-filled, full aperture ratio catheter Produces high quality lumen Minimizes mechanical and thermal trauma Mechanism of Action Photochemical ablation, non-thermal Removes blockages by breaking the bonds of the obstructing plaque directly Plaque is broken down into its fundamental chemistry, not particles Non-thermal light energy breaks molecular bonds of atherosclerotic plaque Before After Plaque Removal Process Crosses through totally occluded lesions Improves blood flow

Slide 8

Our Solution: DABRA Portable Easy to store Intuitive interface Easy calibration Proprietary catheter Features DABRA Can cross and de-bulk wide variety of plaque, unlike some competitors Soft thrombus to hard calcified plaque Tool used by physicians to treat Chronic Total Occlusions (CTOs), unlike some competitors, prior to other alternative treatments Ability to use Above-the-Knee (ATK) and Below-the-Knee (BTK) Monotherapy or adjunct to angioplasty or other treatments Therapy Programs available that do not require a capital equipment purchase Tracks the true lumen Average of approximately two and a half minutes of lasing time Low cost Cost and Time Efficient

Clinically Demonstrated Solutions Safety Record Pivotal Study Multi-site study at four sites in US and Mexico Enrolled 64 patients with target blockage refractory to guidewire crossing Primary Efficacy Endpoint: Successful crossing of target lesion based on angiographic analysis at time of procedure 0% reported serious adverse events (SAE), observed in our 2017 pivotal study and post-market surveillance of DABRA Spectranetics CLiRpath excimer laser catheter demonstrated at 34% SAE rate in their 510(k) application Basis of May 24, 2017 510(k) clearance; Although our pivotal study was not head-to-head with the Spectranetics study, and we may not claim superiority of safety or effectiveness, we believe that the patient population in our pivotal study that supported our 510(k) application was substantially similar to the patient population in the Spectranetics study.

Payors and Reimbursement Approvals / Clearances DABRA: US FDA 510(k), CE Mark PHAROS: US FDA 510(k), CE Mark, CFDA, KFDA Payor Coverage Reimbursement claims for DABRA procedures typically submitted by providers to Medicare or other third-party payor using established Current Procedural Terminology (CPT) codes. Pharos treatments are reimbursable by Medicare and nearly all major insurance companies under three CPT codes that differ based on the affected area to be treated
