Each of the Receiving Party's consultants shall be bound in writing by a confidential disclosure agreement consistent with the terms hereof prior to its receipt of Information. The Receiving Party undertakes to ensure strict compliance with the terms of such confidential disclosure agreements, and shall exercise all of its rights thereunder, including, without limitation, the pursuit of injunctive relief, to ensure the same. Furthermore, upon Warner-Lambert's request, the Receiving Party shall assign to Warner-Lambert its rights under any such confidential disclosure agreement. However, the aforesaid obligations assumed by the Receiving Party hereunder shall not apply to any Information which falls within any of the following categories: (a) Information which is in the public domain at the time of disclosure hereunder or which subsequently has come within the public domain through no fault of or action by the Receiving Party; and (b) Information which is in the possession of the Receiving Party at the time of disclosure by Warner-Lambert or which is independently discovered, after the date hereof, by the Receiving Party without the aid, application or use of the Information, in each such case as evidenced by written records; and (c) Information which is obtained, after the date hereof, by the Receiving Party from any third party which is lawfully in possession of such Information and not in violation of any contractual or legal obligation with respect to such Information. 3.
