in each case, plus such indeterminate number of shares of Common Stock as may be issued to prevent dilution resulting from stock splits, stock dividends or similar transactions in accordance with Rule 416(a) of the Securities Act of 1933, as amended.

Pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated December 20, 2020, by and among the Registrant, Viasat, Inc., a Delaware corporation (“Viasat”), and Royal Acquisition Sub, Inc., a Delaware corporation and wholly owned subsidiary of Viasat (“Acquisition Sub”), Acquisition Sub merged with and into the Registrant, with the Registrant continuing as the surviving entity and a wholly owned subsidiary of Viasat (the “Merger”). The Merger became effective on April 30, 2021 (the “Effective Time”).

As a result of the Merger, any offering pursuant to the Registration Statements has been terminated. In accordance with undertakings made by the Registrant in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that remain unsold at the termination of the offering, the Registrant hereby removes from registration the securities of the Registrant registered but unsold under the Registration Statements as of the Effective Time.
