Explanation of Responses: (1) The Thomson Corporation ("TTC") files this Form 3 pursuant to a Stock Purchase Agreement dated January 12, 1998 (the "Stock Purchase Agreement") among TTC, Sabre Acquisition, Inc., a Delaware corporation and a wholly owned subsidiary of TTC ("Sabre"), and certain stockholders (the "Majority Stockholders") of Computer Language Research, Inc. ("CLR"). The Stock Purchase Agreement requires the Majority Stockholders, who own approximately 74.6% of the outstanding shares of CLR, to tender their shares into Sabre's all cash tender offer for all of the outstanding shares of CLR's common stock and to otherwise sell their shares to Sabre, subject to certain conditions set forth in the Stock Purchase Agreement. Such tender offer is currently scheduled to expire on February 13, 1998, subject to any extension of the expiration date. The tender offer is being made by Sabre pursuant to an Agreement and Plan of Merger, dated as of January 12, 1998 (the "Merger Agreement"), among TTC, Sabre and CLR. Under the terms of the Merger Agreement, after the expiration of the tender offer, Sabre will be merged (the "Merger") with and into CLR, with CLR as the surviving corporation and a wholly owned subsidiary of TTC. Also pursuant to the Stock Purchase Agreement, each Majority Stockholder, with respect to the shares he, she or it owns of record, appoints Sabre as his, her or its proxy to vote his, her or its shares in favor of the Merger and against any other transaction. Consequently, for the purposes of determining TTC's status as a 10% holder, TTC is deemed to own beneficially 10,786,962 shares of CLR common stock pursuant to Sabre's voting power over such shares. However, for Form 3 reporting purposes, TTC is not the beneficial owner of any shares of CLR because TTC currently has no pecuniary interest in the shares subject to the Stock Purchase Agreement and will obtain such pecuniary interest only upon consummation of the tender offer or if it otherwise purchases the shares of the Majority Shareholders pursuant to the Stock Purchase Agreement. (2) Sabre also files this Form 3 pursuant to the Stock Purchase Agreement, but has no securities to report thereunder for the same reason that TTC does not. ** Intentional misstatements or omissions of facts constitute Federal Criminal Violations.
