Explanation of Responses:

( 1 )Due to an administrative error, the initial Form reflected a transaction date of February 29, 2016. However, the transaction date should have been February 3, 2016, the effective date of the merger of TriVascular Technologies, Inc. ("TriVascular") with the Issuer and the date on which the Reporting Person was deemed to receive the shares. ( 2 )The Reporting Person received the shares in exchange for shares of TriVascular common stock pursuant to the merger of TriVascular with the Issuer. Pursuant to the terms of the merger agreement each share of TriVascular common stock automatically converted into the right to receive 0.631 shares of common stock of the Issuer. On the effective date of the merger, the closing price of the Issuer's common stock was $7.42.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
