DUBLIN and LANGHORNE, Pa., April 26, 2012 /PRNewswire via COMTEX/ --Jazz Pharmaceuticals plc (Nasdaq: JAZZ) and EUSA Pharma Inc. today announced that the companies have signed a definitive agreement under which Jazz Pharmaceuticals has agreed to acquire EUSA Pharma, a privately-held, specialty pharmaceutical company with headquarters in the United States and United Kingdom, for $650 million in cash(1) and a potential $50 million milestone payable in cash based upon its lead product, Erwinaze(TM) (asparaginase Erwinia chrysanthemi), achieving a specified U.S. net sales target in 2013.

The transaction would provide Jazz Pharmaceuticals with an expanded portfolio of specialty pharmaceutical products and an enhanced commercial platform, incorporating EUSA Pharma's specialty commercial infrastructure in the United States and Europe and its international distribution network. The combined organization's portfolio would have products marketed in the U.S. and Europe, including Erwinaze, a life-saving treatment for patients with acute lymphoblastic leukemia (ALL). The transaction is expected to be immediately accretive to Jazz Pharmaceuticals' adjusted earnings per share upon closing in 2012 and in 2013 is expected to provide additional revenue of $210 to $230 million, additional adjusted EBITDA of $75 to $85 million, and an additional $0.75 to $0.85 in adjusted earnings per share.

"EUSA Pharma is a compelling strategic fit with our specialty focus and commercial expertise, and furthers our mission to improve patients' lives by delivering therapies that address serious unmet medical needs," said Bruce C. Cozadd, chairman and chief executive officer of Jazz Pharmaceuticals. "This transaction would expand our global footprint and marketed product portfolio to include Erwinaze, a treatment for a life-threatening form of leukemia, as well as other highly specialized products. Our organizations are highly complementary, and we look forward to working with our new colleagues to build an even stronger rapidly-growing company."

"The combination of Jazz Pharmaceuticals and EUSA Pharma would bring together two highly successful businesses, with teams who are passionate about providing patients with access to vital specialty therapies," said Bryan Morton, founder, president and chief executive officer of EUSA Pharma. "There is a strong fit between our two companies' products, people and values, and the combination would represent a positive transaction for the patients we serve, our collective employees and our shareholders. As a larger and stronger combined organization, we would have greater resources to continue our growth toward becoming a leader in the specialty pharmaceutical sector, bringing our medicines to patients worldwide."

EUSA Pharma is a specialty pharmaceutical company founded in 2006, with a portfolio of 10 oncology, critical-care and oncology supportive care products currently marketed directly in the U.S. and Europe and via distributors in other countries. The company's first quarter 2012 net sales were approximately $46 million. Its largest product is Erwinaze, developed as a treatment option for patients with ALL who are hypersensitive to E. coli-derived asparaginase. Approximately 3,600 people younger than 20 years are diagnosed with ALL each year, with a peak incidence between ages 2-5 in the United States.(2,3) Erwinaze was approved by the U.S. Food and Drug Administration in November 2011, and has orphan drug exclusivity through November 2018 and biologic data exclusivity through 2023. In addition, it is currently approved in seven countries outside the U.S., where it is marketed by EUSA Pharma under the trade name Erwinase®.

In addition to ongoing development to expand the available methods of Erwinaze administration to include IV delivery, EUSA Pharma's pipeline includes two additional drug candidates: Asparec®, a pegylated recombinant Erwinia asparaginase currently in phase I development in Europe for the treatment of ALL in patients with hypersensitivity to standard-of-care E. coli-derived asparaginase therapy; and Leukotac® (inolimomab), an anti-CD25 monoclonal antibody in a phase III pivotal study in Europe for treatment of steroid-refractory acute graft versus host disease.

EUSA Pharma's other products in the U.S. are Caphosol® (supersaturated calcium phosphate rinse), ProstaScint® (capromab pendetide) and Quadramet® (Samarium Sm 153 Lexidronam Injection). Outside the U.S., EUSA Pharma's principal products are Caphosol®, Collatamp® (lyophilized collagen implant impregnated with the aminoglycoside antibiotic gentamicin), Fomepizole® (fomepizole), Kidrolase® (Escherichia coli L-asparaginase), and Xenazine® (tetrabenazine).

EUSA Pharma has approximately 180 employees, with operations in the U.S. (Langhorne, PA) and Europe (including offices in Oxford, UK and Lyon, France).

About Erwinaze
Erwinaze is an asparaginase enzyme that depletes the level of asparagine in the bloodstream. Asparagine is essential for cell growth, and its removal from the blood inhibits the growth of cells associated with acute lymphoblastic leukemia. Asparaginase products are derived from bacteria, and approximately 15 - 20% of patients develop hypersensitivity to modern products derived from Escherichia coli, preventing their continued treatment.(4,5,6) Erwinaze, which is produced by Erwinia chrysanthemi, is immunologically distinct from these therapies and is suitable for patients with hypersensitivity to E. coli-derived treatments. Erwinaze was originally discovered by the UK Health Protection Agency. The U.S. FDA approved Erwinaze in November 2011.

Indication and Usage: Erwinaze is indicated as a component of a multi-agent chemotherapeutic regimen for the treatment of patients with acute lymphoblastic leukemia (ALL) who have developed hypersensitivity to E. coli-derived asparaginase.

Important Safety Information

Contraindications: History of serious hypersensitivity reactions to Erwinaze, including anaphylaxis or history of serious pancreatitis, serious thrombosis or serious hemorrhagic events with prior L--asparaginase therapy.

Warnings and Precautions: Discontinue Erwinaze if serious hypersensitivity reactions, including anaphylaxis or severe or hemorrhagic pancreatitis occur. Warnings include: monitor glucose (intolerance may not be reversible; insulin may be needed for hyperglycemia); thrombosis and hemorrhage: discontinue until resolved. Do not use in lactating women and use in pregnant women only if clearly needed.

Common Adverse Reactions greater-than or equal to 1%: Serious hypersensitivity including anaphylaxis, pancreatitis, and abnormal transaminases, coagulation abnormalities (thrombosis, hemorrhage), nausea, vomiting, and hyperglycemia.

Non-GAAP Financial Measures
In this press release, Jazz Pharmaceuticals uses the non-GAAP measures adjusted EBITDA and adjusted earnings per share. Jazz Pharmaceuticals believes these non-GAAP financial measures are helpful in understanding its past financial performance and its potential future results. They are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with the consolidated financial statements prepared in accordance with GAAP. Jazz Pharmaceuticals' management regularly uses these supplemental non-GAAP financial measures internally to understand, manage and evaluate its business and make operating decisions. Compensation of Jazz Pharmaceuticals' employees is based in part on the performance of its business based on these non-GAAP measures. In addition, Jazz Pharmaceuticals believes that the use of these non-GAAP measures enhances the ability of investors to compare its results from period to period. Investors should note that adjusted EBIDTA and adjusted earnings per share, as used by Jazz Pharmaceuticals, may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by Jazz Pharmaceuticals' competitors and other companies.

This press release contains forward-looking estimates of adjusted EBITDA and adjusted earnings per share contributions resulting from the proposed business combination. As used in this press release, with respect to estimated adjusted earnings per share contribution resulting from the proposed business combination, adjusted earnings per share excludes from GAAP net income per diluted share: stock-based compensation, amortization of intangible assets, transaction and integration costs and inventory purchase price adjustments associated with the proposed business combination between Jazz Pharmaceuticals plc and EUSA Pharma, and non-cash interest expense associated with a debt discount and debt issuance costs. With respect to estimated adjusted EBITDA contribution resulting from the proposed business combination, Jazz Pharmaceuticals defines adjusted EBITDA as GAAP net income before interest, income taxes, depreciation and amortization, excluding stock-based compensation, transaction and integration costs and inventory purchase price adjustments associated with the proposed business combination between Jazz Pharmaceuticals and EUSA Pharma. Reconciliations of estimated adjusted EBITDA and adjusted earnings per share contributions to GAAP net income is not provided because GAAP net income generated by the EUSA Pharma operations for the applicable future period is not accessible or estimable at this time. In this regard, Jazz Pharmaceuticals has not yet completed the necessary valuation of the various assets to be acquired in the proposed acquisition, for accounting purposes, or an allocation of the purchase price among the various types of assets. In addition, the final interest and debt expense associated with the transactions contemplated by the commitment letter have not been finalized and are therefore unavailable. Accordingly, the amount of depreciation and amortization and interest and debt expense that will be included in the additional GAAP net income assuming the proposed acquisition is consummated is not accessible or estimable at this time, and is therefore not available without unreasonable effort. The amount of such additional resulting depreciation and amortization and applicable interest and debt expense could be significant, such that actual GAAP net income would vary substantially from the estimated adjusted EBITDA and estimated adjusted EPS contributions included in this presentation.
