Explanation of Responses: (1) The Thomson Corporation ("TTC") files this Form 4 pursuant to an Offer to Purchase (the "Offer") for Cash All Outstanding Shares of Common Stock of Computer Language Research, Inc. ("CLR") at $22.50 Net Per Share by Sabre Acquisition, Inc. ("Sabre"), a wholly owned subsidiary of TTC. The Offer expired, as scheduled, at 12:00 Midnight, New York City time, on Friday, February 13, 1998. At 12:01 a.m., New York City time, on Saturday, February 14, 1998, Sabre accepted 14,364,479 shares of CLR (including 1,067 shares subject to guarantee of delivery) for payment at a price of $22.50 (U.S.) per share. The acceptance of these shares in the Offer resulted in Sabre's ownership of approximately 99% of the outstanding common stock of CLR. On Wednesday, February 18, 1998, TTC merged Sabre with and into CLR, with CLR as the surviving corporation of the merger (the "Merger"). As a result of the Merger, each share of CLR common stock not previously purchased in the Offer was converted into the right to receive $22.50 (U.S.) in cash. Pursuant to instruction 4(b)(iv), TTC reports the entire amount of Sabre's interest in the CLR common stock. (2) Sabre also files this Form 4 pursuant to the Offer, as explained in Response (1) above. ** Intentional misstatements or omissions of facts constitute Federal Criminal Violations.
