We are pleased to announce that Endologix® and TriVascular® have agreed to a merger and expect to become a single company focused on aortic disorders in the first quarter of 2016. Until the deal closes however, we will remain separate companies. Endologix and TriVascular will continue to manage their supplier relationships independently until the merger formally closes.

We want to share our excitement about the future and what this merger means for you. Together with TriVascular, Endologix will be uniquely positioned to offer vascular specialists a comprehensive range of AAA devices to confidently treat more patients more effectively.

Specifically, this merger combines two innovation leaders in endovascular AAA, both of which are singularly focused on the aorta and on developing and providing revolutionary aortic treatments. The merger also brings together three unique and complementary technology platforms — AFX®, Ovation®, and Nellix®— that represent broad product offerings and indications in AAA. The breadth of our solutions will enable clinicians to optimize AAA treatment to the individual requirements of each patient. In addition to a comprehensive range of innovative aortic devices, the merger will enable the combined entity to expand our sales and clinical team.

Together, Endologix and TriVascular have a deep pipeline of new technologies and we remain committed to our business model of physician-driven innovation. Through our ongoing partnership with clinicians, we will continue to develop, manufacture and market revolutionary solutions to further advance endovascular treatment of aortic disease. This does not happen without the important collaborative relationships both Trivascular and Endologix enjoy with their respective suppliers of goods and services. We are in this fight against aortic disease together.

Following the close of the deal efforts to engage with the combined supply base will initate to align the collective efforts of our suppliers with the new combined entity. Until then, please contact me or your Endologix Supply Chain contact if you have any questions about the merger. We will keep you advised about our progress and sincerely appreciate the opportunity to work together.

Sincerely,

Todd Abraham

Vice President - Operations, Endologix
