Commonwealth Biotechnologies, Inc. Acquisition of GL Biochem: Market Update

Shareholders approve sale of the Richmond, Virginia assets as required under the
GL Biochem Asset Purchase Agreement
RICHMOND, Va.–(Business Wire)–
Commonwealth Biotechnologies, Inc. (“CBI”) (NASDAQ Capital Market: CBTE) has
recently announced a definitive share purchase agreement to acquire
Shanghai-based GL Biochem and associated businesses (the “GL Group”), the
largest global supplier of research-grade peptide products and peptide reagents.
Management is pleased to provide a market update regarding the history,
operations and strategy of the GL Group, the industry and marketplace for
peptides and peptide reagents, and progress of the merger transaction.

Background

The GL Group was established in Shanghai by Dr. Hongyan Xu in 1998 and has grown
to become the largest supplier of pre-clinical peptide reagents and custom
peptide synthesis services in the world. The Company has achieved rapid growth
without debt financing or additional capital investment and has expanded the
scale and scope of its operations using only free cash flow from its operations.
Today, the GL Group employees over 800 staff, operates 35,000 ft2 and 120,000
ft2 manufacturing facilities in Shanghai and is in the process of jointly
commissioning a third Shanghai manufacturing facility, `Mimotopes-China`. Over
the past 5 years, the GL Group has demonstrated compound annual revenue growth
of over 40%. Despite the global economic downturn, the GL Group reported a 20%
increase in revenues in the first half of 2009 (unaudited) compared to the same
period last year.

Industry Context

Peptides play an important role in modulating many physiological processes in
the body and therefore have excellent potential as therapeutic agents. Peptide
drugs have a number of advantages over both small molecules and proteins,
including low toxicity and immunogenicity, excellent specificity, high potency
and a low probability of drug-drug interaction problems. Several technical
challenges in the use of peptides as drugs have been overcome in recent years
and they now represent one of the key growth areas in the drug discovery
industry.

Marketplace

GL Biochem caters for the outsourcing requirements of universities, research
institutes, pharmaceutical and biotechnology companies for reagents as well as
research and development services. Large pharmaceutical and biotechnology
companies typically have some capabilities in-house but choose to outsource much
of their research and development work to specialist providers such as GL
Biochem. Pharmaceutical companies are now unable to generate the large number of
necessary candidate compounds in-house and this has led to an increasing trend
for outsourcing of drug discovery research. The worldwide market for custom
peptides was estimated to be between US$250m and US$450m in 2003 and is
projected to grow at an annual average rate of 11.9%, valuing the market between
$550m and $990m by 2010.

Business and Operational Strategy

In recent years, GL Biochem has achieved cost leadership in the research grade
custom peptide industry through exploiting its scale of production, cumulative
experience, competitive labor costs and the manufacture of its own raw
materials. This production cost advantage has allowed GL Biochem to price its
products and services below other major manufacturers and therefore establish a
prominent position in the pre-clinical custom peptide and reagent markets. GL
Biochem sells a portion of its custom peptides and reagent products directly to
the public but also generates significant revenues through an original equipment
manufacturer (“OEM”) strategy, whereby peptides or reagents produced by GL
Biochem are sold to peptide or chemical companies in the West and retailed under
the Western company’s brand name.

Products and Services

GL Biochem develops, manufactures, markets and distributes peptides, peptide
reagents and related services for the life-science sector. GL Biochem`s
offerings include:

* Research-grade peptides: Custom-made peptide molecules for biological research
and drug development applications;
* Peptide libraries: Large numbers of peptides produced in small quantities for
various screening applications in immunology and drug discovery;
* Catalogue peptides: Commonly requested off-the-shelf peptides, typically for
pharmaceutical or cosmetic applications;
* Peptide reagents: Including amino acids, peptide coupling reagents, protecting
reagents and linkers peptide synthesis; and
* Antibodies: Tailored monoclonal and polyclonal antibody production services
for immunology applications.

Merger Progress

On September 3, 2009 CBI entered into a definitive share purchase agreement to
acquire all of the outstanding stock of GL Biochem (Shanghai) Ltd, as well as
all of the outstanding shares of GL Biochem (Danyang) Ltd, GL Peptide (Binhai)
Ltd, and 86% of the shares of GL Peptide (Shanghai) Ltd. Completion of the
transaction is subject to a number of conditions precedent, which among other
things include the sale of the Richmond businesses-CBI Services and Fairfax
Identity Laboratories (collectively, the “Divisions”). The sale of the Divisions
was approved by CBI`s shareholders at the annual meeting of shareholders held on
October 9, 2009. Another material condition is completion of the GL GAAP
qualified audited accounts. These are scheduled for completion on October 15,
2009. Upon fulfillment of these key conditions, CBI anticipates being able to
put the proposed merger to its shareholders for approval by years` end.
