Dendrite International, Inc. Announces Shareholder Rights Plan MORRISTOWN, N.J.- Feb. 16, 2001 - Dendrite International, Inc., the leading provider of sales productivity solutions, analytics, data and sales support services for the worldwide pharmaceutical industry (NASDAQ/NMS:DRTE - news), announced today that its Board of Directors has adopted a shareholder rights plan (the "Rights Plan"). The adoption of the plan is not in response to any known effort to acquire control of the Company. Under the Rights Plan, each shareholder of record on March 5, 2001 will receive a distribution of one Right for each share of common stock of the Company ("Rights"). Initially, the Rights will be represented by the Company's common stock certificates, will not be traded separately from the common stock and will not be exercisable. The Rights will become exercisable only if a person acquires, or announces a tender offer that would result in ownership of 15% or more of the Company's common stock, at which time each Right would enable the holder to buy one one-hundredth of a share of the Company's Series A preferred stock at an exercise price of $120, subject to adjustment. Following the acquisition of 15% or more of the Company's common stock, the holders of Rights (other than the acquiring person or group) will be entitled to purchase shares of the Company's common stock at half-price, and in the event of a subsequent merger or other acquisition of the Company, to buy shares of common stock of the acquiring entity at one-half of the market price of those shares. The Company may redeem the Rights for $0.01 per Right, subject to adjustment, at any time before the acquisition by a person or group of 15% or more of the Company's ordinary shares. The Rights will expire on February 20, 2011. A copy of the Rights Plan will be filed shortly with the Securities and Exchange Commission. ABOUT DENDRITE Dendrite International, Inc.
