EXHIBIT 99 DIGI INTERNATIONAL COMPLETES ACQUISITION OF NETSILICON Combined Company Leads the Growing Connectware Market Minneapolis, February 13, 2002 - Digi International(R) Inc. (Nasdaq: DGII), the leading provider of Connectware(TM), a category of wired and wireless, hardware and software connectivity solutions, and NetSilicon, Inc. (Nasdaq: NSIL), the leading provider of integrated hardware and software for intelligent networked devices, announced today that they have received shareholder approval for the completion of their previously announced merger. Under the terms of the merger agreement, Digi expects to pay $15 million in cash and issue approximately 6.4 million shares of Digi common stock. "The combination of Digi's growing line of Connectware products with NetSilicon's next-generation solutions for intelligent, networked devices creates the broadest and most competitive family of device connectivity solutions in the industry," Digi's Chairman, President and CEO, Joe Dunsmore, stated. "Digi's market leadership position and strong financial condition will enable us to continue to support our strategy of fueling development of products in growth markets, including device servers, terminal servers and embedded network connectivity." Cornelius ("Pete") Peterson, VIII, who previously served as the Chairman and Chief Executive Officer of NetSilicon, has been elected to Digi's Board of Directors and appointed Senior Vice President of Business Development for the merged company. "We believe that NetSilicon's expertise in embedded solutions combined with our early-to-market advantage among OEM customers are the perfect compliment to Digi's Connectware strategy and strong two tier distribution channel," said Mr. Peterson. "The combined company will also benefit from expertise in several key vertical markets, including retail point-of-sale, industrial automation, hospitality, imaging, building controls and home automation." At a Special Meeting of Stockholders held on February 13, 2002, Digi's stockholders approved the issuance of shares of Digi common stock required to consummate the merger. As a result of the merger, each share of NetSilicon common stock issued and outstanding immediately prior to the effective time of the merger has been converted into the right to receive .65 shares of Digi common stock. Each NetSilicon stockholder also had the right to elect to receive cash for some or all of his shares. However, because the cash elections by all NetSilicon stockholders would have required Digi to pay more than $15 million in cash in the merger, under the terms of the merger agreement NetSilicon stockholders who elected to receive cash were cut back on a proportionate basis. Pursuant to the merger agreement the per-share cash payment for each share of NetSilicon common stock is $3.9969, which is equal to .65 times the average per-share closing price of Digi common stock on the Nasdaq National Market over the period of ten trading days ending on the third trading day before the closing of the merger.
