ROCKVILLE, Md., Aug 12, 2010 (BUSINESS WIRE) –
 Emergent BioSolutions Inc. (NYSE: EBS) announced today it has entered   into a definitive agreement to acquire Trubion Pharmaceuticals, Inc.   (Nasdaq: TRBN) for upfront consideration of $96.8 million of value and   up to $38.7 million of success-based milestones, resulting in a total   consideration of up to $135.5 million. The acquisition will diversify   Emergent’s product development pipeline with the addition of Trubion’s   two clinical-stage product candidates focused on the targeted disease   areas of oncology and autoimmunity. The acquisition also offers novel   platforms, consisting of proprietary Small Modular Immunopharmaceutic   (SMIPTM) and SCORPIONTM technologies, for developing additional   innovative therapeutic candidates.
The acquisition of Trubion is expected to further Emergent’s position as   a leading, fully integrated biopharmaceutical company focused on the   manufacture, development and commercialization of vaccines and antibody   therapeutics. Trubion’s clinical and preclinical stage programs, as  well  as its leading edge science, will expand Emergent’s product  development  pipeline and significantly broaden its antibody-based  capabilities.  Upon closing, the transaction is expected to provide  approximately $20  million in cash, net of customary closing costs, and  $70 million of net  operating losses (NOLs) that are expected to be used  over the next ten  years.
Trubion’s development pipeline is comprised of two clinical-stage   therapeutic candidates and multiple preclinical programs, including:
 - a clinical-stage CD20 directed SMIP candidate (SBI-087) for the   treatment of Rheumatoid Arthritis (Phase 2) and Systemic Lupus   Erythematosus (Phase 1/2) in partnership with Pfizer;
- a clinical-stage CD37 targeted SMIP candidate (TRU-016) for the   treatment of Chronic Lymphocytic Leukemia (Phase 1/2), Non-Hodgkin’s   Lymphoma (Preclinical/Phase 1) in partnership with Abbott; and
- promising preclinical candidates based on the novel, proprietary   SMIP and SCORPION platforms for the treatment of selected oncology and   autoimmune diseases.
Fuad El-Hibri,   chairman of the board of directors and chief executive officer of   Emergent BioSolutions, stated, “This acquisition strengthens Emergent’s   biologics capabilities in two key aspects. First, it diversifies our   product pipeline beyond infectious diseases into the two high growth   areas of oncology and autoimmunity. And, second, it broadens our   monoclonal antibody therapeutic capabilities. Emergent’s stable vaccine   franchise, substantial capital resources, and expertise in  manufacturing  and product development combined with Trubion’s  world-class therapeutic  platform technologies and clinical-stage  development programs should  translate into significant value over the  near and long term.”
Steven Gillis, Ph.D., executive chairman of the board of directors and   acting president of Trubion, stated, “The acquisition of Trubion by   Emergent should accelerate the continued development of our leading   products and technologies. We believe the combination of Emergent’s   strong financial position and expertise in development of biologics with   Trubion’s innovative SMIP and SCORPION protein therapeutic product   candidates and technologies will provide an efficient and effective   development path for these promising products and technologies.”
Emergent will maintain research facilities in Seattle, Washington upon   completion of the acquisition, and the location will become a   therapeutics-focused product development site for the combined company.   Taking this transaction into account, Emergent is reaffirming its  annual  2010 forecast of $275 to $300 million in total revenues and $40  to $50  million in net income.
 Terms of the Agreement
 The transaction has been approved by the Boards of Directors of both   companies and is subject to customary closing conditions, including the   approval of the acquisition by stockholders of Trubion Pharmaceuticals   and the expiration or termination of the applicable waiting period  under  the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
Under the terms of the agreement, each share of Trubion Pharmaceuticals   common stock will be converted into the right to receive an upfront   payment of $1.365 per share in cash and 0.1641 shares of Emergent   BioSolutions common stock. The upfront payment represents a value of   $4.55 per share, or approximately $96.8 million, based on Trubion’s   total common shares outstanding, the net value of dilutive stock   options, and the trading average of Emergent BioSolutions common stock   for the five days prior to the signing of the definitive agreement. In   the aggregate, Emergent will issue approximately 3,350,000 shares of its   common stock as part of the upfront consideration, which after the   closing of the merger will represent approximately 9.2% of Emergent’s   total shares outstanding. Certain of these shares will be subject to   lockup provisions. Trubion Pharmaceuticals stockholders will also   receive one Contingent Value Right (CVR) per share, which will entitle   the holders to receive cash payments based upon achievement of five   predefined Phase 2 and Phase 3 clinical study initiation milestones and   one manufacturing-related milestone. The total potential aggregate  value  of the CVRs is $38.7 million over a 36-month period following the   closing of the merger.
 Details regarding the predefined milestones are as follows:
    | Milestone Events | Applicable Payments | 
  | Initiation of the first Phase 2 clinical study for TRU-016 | $1.75 million | 
  | Release of TRU-016 manufactured for use in clinical studies | $10.0 million | 
  | Initiation of dosing in the first Phase 2 clinical study for a non-CD20 target | $0.75 million | 
  | Initiation of the first Phase 3 clinical study in oncology indication for TRU-016 | $15.0 million | 
  | Initiation of dosing in the first Phase 3 clinical study for the first major indication for CD20 candidate | $6.25 million | 
  | Initiation of dosing in the first Phase 3 clinical study for the second major indication for CD20 candidate | $5.0 million | 
  
 The acquisition of Trubion is expected to close in the fourth quarter of 2010.
