AND CAPSULE COMMUNICATIONS, INC. ANNOUNCE AGREEMENT TO MERGE Combined Company Positioned to Provide More Complete Systems Solution for Telecommunications Market Little Falls, New Jersey and Bensalem, Pennsylvania, July 18, 2001 Covista Communications, Inc. (NASDAQ: CVST) and Capsule Communications, Inc. (OTC Bulletin Board: CAPS.OB) today announced the execution of a definitive merger agreement. Under the terms of the agreement approved by the boards of directors of both companies, Capsule would become a wholly-owned subsidiary of Covista. The shareholders of Capsule other than its controlling shareholder would receive 0.1116 shares of Covista common stock for each share of Capsule common stock, subject to adjustment as provided in the agreement; and Henry G. Luken, III, the controlling shareholder of Capsule, would receive 0.0838 shares of Covista common stock for each share of Capsule common stock. Based upon the closing price of $5.99 for Covista's common stock on July 17, 2001, the transaction would have an estimated value, on a fully diluted basis, of approximately $12,576,000. Upon the closing of the transaction, the former Capsule shareholders would hold approximately 15.5% of the combined company. The transaction, anticipated to close in the fourth quarter of 2001, is subject to approval by the shareholders of both companies and other customary closing conditions, including obtaining necessary regulatory approvals. Henry Luken, the beneficial owner of approximately 69.7% of Capsule's outstanding common stock, has expressed his intention to vote all of his shares in favor of the merger. Mr. Luken also is Chairman and a principal shareholder of Covista, owning approximately 30.4% of its outstanding shares. Covista reported revenues of approximately $133,230,000 for its fiscal year ended January 31, 2001. Capsule's revenues totaled approximately $37,368,000 for its fiscal year ended December 31, 2000. The combined company is expected to have over 230 employees upon completion of the merger. It is anticipated that Capsule will continue to offer communications and Internet-related services under the Capsule name. BENEFITS OF THE MERGER "We believe this transaction will produce significant benefits for both customers and shareholders," said John Leach, Covista's President and CEO. "The combination of Covista and Capsule will result in a company having greater economies of scale than either Capsule or Covista could achieve operating separately in the telecom business. The merger should further broaden an already diverse customer base and allow the combined sales force to expand market share through existing relationships with customers that purchase different but complementary services." "Together," Mr. Leach added, "Covista and Capsule are committed to becoming a significant provider of integrated telecommunications and data services that should offer meaningful cost, size and logistics benefits to the shareholders and customers of the combined companies. Focusing their efforts as a combined entity in this lucrative and large market segment should enhance the opportunities for success." "The services which Capsule and Covista provide complement one another," said David Hurwitz, President and CEO of Capsule. "Covista has established itself in the medium-size enterprise market, whereas Capsule's strength has been in the small- to medium-size enterprise market. In addition, the trend in the telecommunications industry towards larger service providers offering bundled products, including local and long-distance telecommunications, Internet access and data services, should enable the combined company to operate with increased competitiveness and pricing flexibility." Mr. Hurwitz further noted, "The combined company also should be able to offer international terminations at more favorable rates for the current domestic business and carrier customers of both Covista and Capsule." "For the past several months we have been telling our shareholders, customers and the business community about our plans to expand both the product offerings and the geographical base of Covista's business," Mr. Leach commented. "Signing this agreement today is another step toward achieving our main goals of revenue growth and profitability. The synergies Capsule presents make this deal strategically important as we branch out into new markets." Mr. Hurwitz added, "We are very excited about combining forces with Covista, a company which has clearly demonstrated the technical and financial leadership that will be keys to success in the future." Following the close of the transaction, Henry Luken will retain his position as Chairman of the Board of the combined companies and John Leach will continue to serve as President and CEO. Additionally, David Hurwitz, Capsule's President and CEO, will continue in the role of President of the Capsule subsidiary of Covista.
