Forest Labs enters definitive merger agreement to acquire Clinical Data

Forest Laboratories, Inc. (Forest) (NYSE: FRX) and Clinical Data, Inc. (Clinical Data) (NASDAQ: CLDA) today announced that they have entered into a definitive merger agreement pursuant to which Forest will acquire Clinical Data, a specialty pharmaceutical company focused on the development of first-in-class and best-in-category therapeutics, for $30.00 per share in cash plus contingent consideration of up to $6.00 per share that may be paid upon achievement of certain commercial milestones related to Viibryd™. The upfront consideration of $30.00 per share represents a 6.6% premium to the volume-weighted average trading price of CLDA stock since the first trading day after the company announced the approval of Viibryd and that it was considering a potential change of control transaction and a 19.2% premium of the closing price on that day and totals $1.2 billion on a fully diluted basis, net of net cash acquired. Forest will finance the transaction with existing cash. The transaction was approved by the boards of both companies and is expected to be completed in the second quarter of 2011, subject to customary closing conditions.

The transaction will allow Forest to leverage its existing presence in the antidepressant category through the launch of Viibryd (vilazodone HCL tablets) which was developed by Clinical Data and approved by the FDA on January 21, 2011 for the treatment of adults with major depressive disorder (MDD). Viibryd is a selective serotonin reuptake inhibitor and a 5-HT_1A receptor partial agonist. With Celexa® and Lexapro®, Forest has a proven track record of successfully commercializing novel anti-depressants. The market for the treatment of MDD is over 200 million prescriptions annually and increasing. Forest plans to launch Viibryd in the U.S. during the second half of 2011. Viibryd is expected to retain market exclusivity until March 2020 including full patent term extension of its composition of matter patent and anticipated pediatric exclusivity. Other patents may further extend this period.

Howard Solomon, Chairman, Chief Executive Officer and President of Forest Laboratories said, "We are pleased to enter into this agreement with Clinical Data. Depression is a debilitating disease that affects the daily lives of millions of patients. We believe that we are uniquely positioned to bring Viibryd to market in light of our long and successful experience of clinical development and expertise in the antidepressant market. This transaction is consistent with our strategy to acquire new products that will help offset the loss of revenues due to patent expiries. Viibryd will be the second new product that we expect to launch this year in addition to Teflaro™. In addition, we are hopeful to obtain FDA approval later this quarter for Daxas (roflumilast), for the treatment of COPD. We plan to submit New Drug Applications for aclidinium and linaclotide in the second half of this year and for two additional products in calendar 2012."

The transaction is expected to be dilutive, net of synergies, to Forest's earnings per share for the next three fiscal years, with earnings per share dilution in the range of ($0.55) to ($0.65) in fiscal 2012. The transaction may become accretive during fiscal 2014. The transaction is not expected to impact Forest's fiscal year 2011 financial guidance. The launch of Viibryd will require significant incremental marketing and sales investment, including a planned sales force expansion. Additional sales resources will be necessary in order to adequately support Viibryd, as well as our currently marketed products Teflaro, Savella®, Bystolic®, Namenda and Lexapro and the anticipated launch of Daxas (roflumilast), pending FDA approval in calendar 2011.

In addition, the transaction brings to Forest Stedivaze™ (apadenoson), a potent agonist of the adenosine A2A receptor subtype with improved selectivity for this receptor over other subtypes (A1 and A2B). Stedivaze is a coronary vasodilator in Phase III development as a pharmacologic stress agent for radionuclide myocardial perfusion imaging (MPI).

Under the terms of the definitive merger agreement, it is anticipated that Forest will promptly commence a cash tender offer to purchase all of the outstanding shares of Clinical Data common stock for $30.00 per share in cash and the non-transferable contractual right that could deliver up to an additional $6.00 per share in cash if U.S. net sales of Viibryd over four consecutive fiscal quarters commencing from the date of the closing of the transaction reach or exceed $800 million within the first 5 years ($1.00 per share), $1.1 billion within the first 6 years ($2.00 per share) and $1.5 billion within the first 7 years ($3.00 per share). The terms of the contingent payments reflect the parties' agreement over the sharing of potential economic upside benefits from future U.S. net sales of Viibryd and do not necessarily reflect anticipated sales of the product. There can be no assurance such levels of net sales will occur or that any or all of the contingent payments will be made. In the tender offer Forest would also offer to purchase certain outstanding notes and warrants issued by Clinical Data that are convertible into or exercisable for shares of Clinical Data common stock. Under the terms of the definitive merger agreement, the transaction is conditioned upon, among other things, satisfaction of a minimum tender condition requiring that the securities tendered in the tender offer represent approximately 78.8% of the outstanding shares of Clinical Data common stock on a fully-diluted basis. In addition the transaction is subject to the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. In the event that the minimum tender condition is not met, and in certain other circumstances, the parties have agreed to complete the transaction through a one-step merger after receipt of stockholder approval. Randal J. Kirk, the Chairman of Clinical Data's board of directors, and certain of his affiliates, as well as other directors and officers of Clinical Data, which beneficially own approximately 52.3 percent of Clinical Data's outstanding shares on a fully diluted basis, have entered into agreements pursuant to which they will tender their outstanding securities into the tender offer and, if applicable, vote their outstanding shares of Clinical Data common stock in favor of the merger.
