SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 FORM 8-K CURRENT REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 Date of Report (Date of earliest event reported): May 30, 2001 Interneuron Pharmaceuticals, Inc. --------------------------------- (Exact name of registrant as specified in its charter) Delaware 000-18728 04-3047911 ---------------------- ----------- -------------- (State or other (Commission (IRS Employer jurisdiction of File Number) Identification incorporation) Number) One Ledgemont Center 99 Hayden Avenue Lexington, MA 02421 ----------------------------------- (Address of principal executive offices) Registrant's telephone number, including area code: (781-861-8444) ITEM 5. Other Items. ------- ------------ On May 30, 2001, Interneuron Pharmaceuticals, Inc. (the "Company") entered into an Indemnity and Release Agreement (the "Agreement") with American Home Products Corporation ("AHP") which provides for AHP's indemnification of the Company with respect to certain classes of product liability claims filed against the Company related to the prescription drug Redux(R), which was withdrawn from the market in September 1997. Pursuant to the Agreement, AHP has agreed to indemnify and hold harmless the Company and its officers, directors and certain employees (collectively, "Interneuron Indemnified Parties") against all losses after the date of the Agreement (including, damages, settlements and judgments) arising from Redux- related claims by (i) persons who have already opted out of AHP's National Class Action Settlement Agreement in Brown v. AHP, No. 99-20593 (E.D. Pa.) (the "Brown Settlement") and (ii) any Brown class member alleging Primary Pulmonary Hypertension (PPH) as a result of the use of Redux. AHP further agreed to assume the Company's defense in all litigation arising out of such indemnified claims. In addition, AHP agreed to assume the defense of and fund all future legal expenses in Redux-related product liability litigation brought by claimants other than those described above. AHP further agreed to provide additional insurance coverage to fund losses resulting from any settlements or judgments in current or future Redux-related product liability claims that are not covered by AHP's indemnification obligations under the Agreement. The Company believes that AHP's indemnification of certain claims, the insurance provided by AHP for other claims, and AHP's funding of legal expenses, as described above, along with the Company's existing insurance, will be sufficient to address the Company's potential Redux product liability exposure. However, there can be no assurance that uninsured or insufficiently insured Redux-related claims that may arise in the future will not have a material adverse effect on the Company's future business, results of operations or financial condition. The Agreement does not provide indemnification or defense by AHP of the Interneuron Indemnified Parties for losses and litigation expenses (i) incurred by Interneuron Indemnified Parties prior to the date of the Agreement, (ii) arising out of claims asserted against Interneuron Indemnified Parties for breaches or violations of any state or federal securities laws or (iii) any costs related to regulatory or government actions. 2 Pursuant to the Agreement, AHP and the Company agreed also to mutually release each other for Redux-related claims. In addition, the Company agreed (i) to dismiss with prejudice its lawsuit, Interneuron v. AHP, No. 00-294 (Mass. Superior Court, Middlesex County), which the Company filed in January, 2000, (ii) to withdraw its appeal to the United States Third Circuit Court of Appeals from the order approving the Brown Settlement, and (iii) to withdraw its counterclaims against AHP in all pending Redux-related product liability litigation.
