The reverse split will be implemented coincident with the Rare Medium merger and is intended to also enable the Company to meet NASDAQ listing requirements and increase its marketability to investors. "The reverse share split is part of a series of actions, including the Rare Medium merger, which we are taking to improve our balance sheet and put the company on an improved financial footing going forward," stated Walter V. Purnell, Jr., president and CEO of Motient. Purnell added, "Given the recent pressure on our share price and in the best interest of our shareholders, we felt that a reverse share split was prudent to help improve the liquidity and marketability of Motient." The reverse stock split will be voted on by shareholders at the special shareholder's meeting on the Rare Medium merger, which is expected to be scheduled for late September. Upon the effectiveness of the reverse stock split, 10 shares of common stock will be converted and reclassified as one share of post-split common stock, and each existing stock certificate will represent one-tenth the number of shares shown thereon. Cash will be paid in lieu of fractional shares. Motient also commented that a reverse stock split will not have an impact on the value of its pending acquisition of Rare Medium; however, upon the effectiveness of a reverse stock split, the terms of Motient's Series A preferred stock to be issued in the merger would be equitably adjusted to reflect the reverse stock split.
