Explanation of Responses:

1. This transaction involved non-qualified stock options, the terms of which provided for the purchase of shares of common stock possessing certain liquidity restrictions. As such, the exercise of the options followed the sell to cover process, whereby a certain number of the shares acquired through exercise were sold in the open market, with the proceeds used to fund the exercise price and associated income and employment taxes. The balance of the shares acquired through exercise are subject to multi-year restrictions on transfer or sale.

2. The 264 shares being sold were acquired under the Vicor 2017 Employee Stock Purchase Plan on 8/31/18.

3. This stock option is exercisable in full.
