Summary Physicians’ efforts to help their severe emphysema patients are hampered by a lack of good therapeutic tools Pulmonx produces minimally invasive medical devices to expand treatment options for emphysema patients – These have been available for many years in Europe – Multiple randomized trials have already been completed and have helped identify which patients are most likely to benefit Based on this clinical experience, there is a US pivotal study of the Pulmonx Zephyr® EBV recruiting in your area

The core issue in advanced emphysema is reduced elasticity, leading to gas trapping and lung hyperinflation Emphysema Healthy Lung Lung with Emphysema Diseased region compresses healthier region, making breathing difficult Breathing is easy; Lung expands and contracts normally Tissue destruction reduces elasticity and gas exchange Tissue is elastic with large surface area

The Burden of Emphysema Creates a downward spiral of deconditioning and lung function decline that results in death 6 Million people in Europe and the US suffer from emphysema; 1.5M of these are severe or very severe 4 th leading cause of death worldwide Costs the US healthcare system >$30B in direct expense annually

7 7 © 2014 Pulmonx. All rights reserved CL070_24FEB2015 The Zephyr® EBV is an investigational device in the United States. Limited by U.S. law to investigational use. New Options Pulmonx developed the Zephyr® Endobronchial Valve (EBV) System for bronchoscopic lung volume reduction – More than 60 clinical articles have been published to-date 1 – Approved in Europe in 2003 and over 9,000 patients treated outside of the USA – Supplements but does not replace ongoing medical management by their physician The EBV system is available as an investigational device through the LIBERATE clinical study in the USA 1 Data on file at Pulmonx

Bronchoscopic Lung Volume Reduction (BLVR) with Zephyr® EBV Minimally invasive, investigational implant reduces the volume of the diseased part of the lung Allows the healthy part of the lung to expand and function efficiently

What is the LIBERATE study device? The Zephyr® EBV System consists of: – Endobronchial Valve (EBV) – Valve Loading system – Delivery Catheter (EDC)

The Zephyr® EBV Flexible frame Designed to seal against target lung airway and prevent tissue ingrowth One-way valve Designed to close when breathing in and open when breathing out

11 11 © 2014 Pulmonx. All rights reserved CL070_24FEB2015 The Zephyr® EBV is an investigational device in the United States. Limited by U.S. law to investigational use. What is the study procedure? A bronchoscope is inserted through the nose or mouth and into the lungs The Zephyr® EBV is delivered through the bronchoscope – If needed, the EBV may also be removed through the bronchoscope

Lung Volume Reduction with EBVs The Zephyr® EBV allows air and secretions to pass out through the valve but not back in, resulting in lung volume reduction In turn, the healthy part of the lung expands again and takes part in the exchange of oxygen and carbon dioxide

What is collateral ventilation? If there is low collateral ventilation, the EBVs will keep air from entering the diseased area, reducing lung volume. If there is collateral ventilation, air can enter the diseased area from behind the EBVs and lung volume will not reduce. The Chartis® System can assess this prior to implanting the EBVs into the lung. Collateral ventilation is like a backdoor for airflow between lobes in the lungs

The Chartis® System consists of: – Console for measuring flow and pressure Chartis® System for Collateral Ventilation Assessment – Balloon catheter Similar to the EBV, the low pressure balloon catheter is delivered through a bronchoscope
