Background to the Company

· Abzena's mission is to enable R&D companies to develop better biopharmaceutical products - e.g. therapeutic antibodies and proteins - with one or more of the following attributes: better efficacy, fewer side effects, more predictable quality and/or improved patient compliance

· Over 70 per cent. of the revenue of the world's top ten selling medicines is derived from biopharmaceuticals including the world's largest selling drug, HUMIRA®. Worldwide revenue from biopharmaceutical products was $169 billion in 2012 and this figure is forecast to exceed $220 billion in 2017

· Abzena is a revenue-generating life sciences company (FY2014: £5.8 million) with a range of complementary services and technologies (covering biopharmaceutical immunogenicity assessment, antibody and protein engineering, manufacturing cell line development and bioconjugation), which provide two sources of income:

o High-margin fee-for-service income from a broad customer base which includes the majority of the top 20 biopharmaceutical companies

o Milestone payments and/or future potential royalties from the development and commercialisation of products created with the Group's technologies with more than 30 licence and option agreements currently in place and five customers' products undergoing clinical development for a wide range of diseases, including cancer, autoimmune and inflammatory diseases

· The market which Abzena serves is growing, driven by an increase in outsourcing of R&D by major biopharmaceutical companies, as well as by biotechnology companies looking externally to access expertise and skills. The US market for applied research and preclinical drug development, the areas in which Abzena operates, is estimated at $9.6-$11.5 billion; the majority of Abzena's revenues are derived from providing services and access to its technologies to US customers

Strategy and Use of Proceeds

Abzena's strategy is to continue its growth as a provider of services and technologies to address critical R&D issues to enable the development of better biopharmaceuticals. Organic growth of the service business will be driven through leveraging of the Group's brands and cross-selling to the Group's existing and new customers. Further revenue growth will be driven by progression of customer products, being developed under licences granted by the Group, thereby leading to receipt by the Group of milestone payments and royalties.

Abzena's senior management has a track record in identifying, acquiring, integrating and growing businesses. The directors of Abzena believe there are opportunities for the Group to consolidate further businesses within the fragmented market in which it operates by adding complementary services and technologies to drive service revenue growth and long-term value creation through product royalties.

The net proceeds of the Placing payable to the Company will be used to:

· Invest in short- and long-term drivers of revenue:

o Increase service capacity to meet growth in demand

o Developexisting technologies to enhance licence revenue opportunities

o Create value through co-investment in adoption of the Group's technologies by its partners to create better biopharmaceutical products

o Developcomplementary new services and technologies in-house

· Acquire complementary services and technologies, through in-licensing and/or M&A

· Provide additional working capital
