(“Synchronoss”) signing the merger agreement on December 5, 2016. This disclosure includes references to other parties who were involved in the process, but does not identify them by name, which is consistent with applicable disclosure rules and the Company’s obligations under confidentiality agreements.

The Background of the Merger section also references that the Company has received an unsolicited non-binding indication of interest to purchase the Company at a per share price of $13.50.

The Company’s Board of Directors has taken no position as to the advisability or desirability of such indication of interest. As indicated in the disclosure, the Company’s Board of Directors unanimously recommends that Company stockholders accept Synchronoss’ offer and tender their shares into the offer.

Company employees should continue to engage in authorized pre-closing integration planning meetings with members of the Synchronoss team and should otherwise continue to conduct business in the ordinary course, consistent with past practice.
