PART I

Overview

Commonwealth Biotechnologies, Inc. (the “Company” or “CBI”) is a specialized life sciences outsourcing business that offers cutting-edge expertise and a complete array of discovery chemistry and biology products and services through its subsidiary companies: CBI Services, Fairfax Identity Labs (“FIL”), Mimotopes Pty Limited (“Mimotopes”) and Exelgen Limited (“Exelgen”) (formerly Tripos Discover Research Ltd).

The market for drug discovery outsourcing was $4.1 billion in 2005 and is expected to grow at 20% annually to reach $7.2 billion in 2009 (Kalorama Information, 2006). CBI is positioned to compete in this growing market with an experienced and business-focused management team and over 100 highly trained scientific staff located in three laboratories in Richmond (Virginia), Melbourne (Australia) and Bude (U.K.) and sales offices located in the U.S., U.K., and Asia/Pacific.

CBI aims to build a leading global contract drug-discovery solutions business by pursuing a number of strategic initiatives aimed at increasing revenues, increasing margins, managing costs and most importantly, increasing market awareness and market value. Specifically, CBI intends to achieve these objectives by:

Business Units

Revenues from all four business units are derived principally from providing macromolecular synthetic and analytical services to researchers in the biotechnology industry or to researchers who are engaged in life sciences research in government or academic labs throughout the world. This arrangement distinguishes CBI from many other biotechnology companies in that revenues are derived from services rather than from the successful commercialization of a new biotechnology product. CBI believes that Mimotopes, Exelgen, CBI Services and FIL have all developed a strong reputation as leading providers in their respective markets. Their operations, areas of expertise and value propositions are outlined below:

CBI Services (Richmond, Virginia)

CBI Services provides a wide array of life-science solutions in the areas of bio-defense, laboratory support and contract research. CBI Services has broad expertise in the most current analytical chemistries, microbiology applications and molecular biology technologies and has a reputation as a provider of novel and imaginative research and development solutions. CBI Services offers all services under the Food & Drug Administration’s (“FDA”) Good Laboratory Practices (“GLP”) guidelines. Selected services are also offered under the Good Manufacturing Practices (“GMP”) and Good Clinical Practices (“cCMP”) guidelines. CBI’s quality assurance office manages all regulated services.

FIL (Richmond, Virginia)

FIL has been at the forefront of DNA technology of profiling for identity since it opened its doors in 1990. FIL’s rigorous standards are designed to provide credible evidence that affects decisions regarding criminal trials, paternity, immigration, estate settlement, adoption, and other issues of identity. FIL provides Forensics, Paternity and Convicted Offender DNA Index System (“CODIS”) services to government and private concerns. FIL is accredited by the American Association of Blood Banks, the National Forensic Science Technology Center, the State of New York and pursuant to the Clinical Laboratory Investigation Act (“CLIA”). Its employees have extensive laboratory and courtroom experience.

Mimotopes (Melbourne, Australia)

Mimotopes is an industry leader with over 16 years experience in the development, synthesis and distribution of research grade peptides for the drug discovery industry. CBI believes that Mimotopes’ patented synthesis technologies, state-of-the-art facilities and highly educated and experienced staff make it one of the leading research grade peptide synthesis companies in the world. Mimotopes’ products and services are delivered to both commercial clients and to discovery and alliance partners. In 2006 and 2007, Mimotopes developed significant partnerships with peptide partner company PepScan and global key life science companies

2

Genzyme Pharmaceuticals and Invitrogen. Mimotopes’ partnership with Genzyme Pharmaceuticals, a leading manufacturer of clinical-grade peptides, has created a brand that provides a total suite of peptide products and acts as an integrated ‘one-stop-shop’ for peptide customers.

Exelgen (Bude, United Kingdom)

Exelgen (formerly Tripos Discovery Research Ltd), based in Bude, Cornwall, U.K., is a leading, knowledge-driven, drug discovery services business that provides pharmaceutical and biotechnology companies with novel approaches to drug discovery. Applying proprietary computational design and therapeutic medicinal chemistry tools and expertise, CBI believes that Exelgen is able to reduce drug discovery timelines by up to 30%. Since 1997, Exelgen has been offering compound libraries under the LeadQuest® brand, screening libraries under the LeadScreen® brand and custom de novo compound libraries under the LeadSelect® brand.

Target Markets

Each of CBI’s business units has its own distinct capabilities and market focus, although significant overlap exists between the customer bases. The markets served by each of the business units are shown below:

CBI Services, Exelgen and Mimotopes all cater to the outsourcing requirements of pharmaceutical and biotechnology companies for reagents (such as peptides, proteins and small molecules), as well as drug research and development. The adoption of outsourcing by the pharmaceutical and biotechnology industries is driven by three major factors:

(1) Speed. Faster discovery results accelerate the time to fail or advance a drug through the development pipeline. Eliminating bad leads early or shaving weeks or months from the time it takes to get a drug to market can mean millions of dollars in cost savings and added revenues.

(2) Quality. All the advantages of an accelerated drug discovery program can be jeopardized if the results do not meet the strict quality standards of the pharmaceutical industry. High quality results depend on quality control, quality equipment and quality people.

(3) Cost. Speed and quality are necessary but insufficient conditions for success. The economic scarcity problem of unlimited wants and needs and limited resources applies to drug discovery outsourcing as well. The more suppliers can offer for less, the more successful they will be.

CBI believes that market growth is spurring investment in contract research organizations and attracting new providers to the market, many from low-cost territories such as Asia. CBI believes that it is well positioned to compete in this growing market with over 100 highly trained staff located in three world-class laboratories based in Richmond (Virginia), Melbourne (Australia) and Bude (U.K.). The time difference between the sites means that the Company operates virtually around the clock across its three primary research sites. Strong links to preferred suppliers in Asia also means that its customers can access the best mix of fast, secure, high quality, and innovative research services at globally competitive prices.

Market Dynamics

Pharmaceutical companies have been struggling for some time to maintain the growth expected of them by the market. CBI believes that the primary reason for this is the increasing difficulty in discovering new drugs, in particular blockbusters (drugs with greater than $1 billion in sales). This led to a consolidation of the industry in the 1990s and the formation of the new “big Pharmas”. However, CBI believes that these mergers were largely unsuccessful because they failed to address the real problem, the falling rate at which candidate compounds were entering the development pipeline as commercial drugs. With a combination of increasing regulatory requirements and a more competitive marketplace, it takes an increasing number of high quality candidate compounds to produce the same number of successful drugs.

Pharmaceutical companies, and in particular big Pharmas, have realized that they cannot generate the large number of necessary candidate compounds in-house, and this has led to a trend for these companies to outsource large amounts of their drug discovery research. A market intelligence report by Kalorama Information (2006) indicates that outsourcing was worth $4.1 billion in 2005, and is projected to grow at a rate of 20% annually to reach $7.2 billion in 2009. The report also states that recent improvements in biology have made chemistry the major bottleneck in the product pipeline. Chemistry and optimization (key areas of expertise for Exelgen) now make up 44% and 19% of outsourcing respectively. It has been estimated that an additional 30,000 chemists will be required worldwide by 2010 and that medicinal and process chemists will be the specialties in highest demand.

Although the dollar value of the drug discovery outsourcing market is huge, it is comprised of a relatively small number of mature customers. The vast majority of this market lies in the U.S., Western Europe and Japan. It is a very sophisticated market consisting of large multinational pharmaceutical companies, small pharmaceutical companies, generic manufacturers and drug discovery companies.

The most attractive global customers are the big Pharmas, including Pfizer, GSK, Merck, AstraZeneca, Novartis, Eli Lilly and Bristol-Myers Squibb. They are active companies and have the capacity to offer large contracts. Many have centralized outsourcing departments that match the specific needs of a particular project to contractors with specific expertise in that area. They are very experienced at outsourcing and have the resources to overcome barriers such as distance, due diligence inspections, and technology transfer issues which may deter some smaller companies from outsourcing to overseas contractors. Small drug discovery companies are also an attractive opportunity but the low profile of many of these companies, coupled with their limited resources and experience in outsourcing, make marketing to them more difficult. The Kalorama Information report indicates that suppliers of synthetic services to the pharmaceutical industry are numerous but small, and mainly based in the U.S. or Europe. The largest supplier, Albany Molecular, has only a 6% market share.

During the course of 2007, CBI significantly enhanced its research and development outsourcing capabilities through the acquisition of Mimotopes and Exelgen. Although there is increasing competition from low-cost providers in China and India, recent concerns over production standards and quality in some low-cost territories has led to a flight to quality providers. With a strong reputation for price competitive and high quality service and product delivery, CBI believes that it is well positioned to grow business in high-value niches in the pharmaceutical outsourcing market because of its unique combination of proprietary informatics systems and contract chemistry and biology services. CBI’s “one stop shop” model is already attracting new customers and winning a broader range of business from existing customers.

Growth Strategy

During the course of 2007, the Company acquired U.K.-based medicinal chemistry company Exelgen and Australian-based peptide chemistry company Mimotopes, transforming the Company into a full-service pre-clinical drug discovery services provider with a global base of operations and clients. These transactions have transformed CBI into a full-service pre-clinical drug discovery services provider with a global base of operations and clients, and CBI believes that it is well positioned for continued strong growth with a record number and value of new contracts over the last year, a growing market for high-quality research and development outsourcing and a dynamic and commercially driven management team. CBI recorded revenues of $12.4 million in 2007, up from $6.5 million in 2006, with a net loss of $2.8 million, up from $1.1 million in 2006. However, these results significantly under-play the Company’s operating performance because of the timing of the Exelgen acquisition and significant one-time costs associated with

4

the acquisition. In December 2007, CBI completed a company-wide reorganization aimed at realigning its sales and marketing capabilities and attaining cost synergies following the Mimotopes and Exelgen transactions. Beginning in 2008, CBI expects cost synergies, through targeted redundancies and salary savings to generate annual savings of $1.6 million.

With a focus on both revenue and cost synergies, integration of Mimotopes and Exelgen into the Company in 2007 resulted in new contract signings. CBI expects to build on these successes to become a leading global contract drug-discovery solutions business. The Company will pursue a number of strategic initiatives aimed at increasing revenues, increasing margins, managing costs and increasing market awareness and value. These include:

CBI will also actively pursue opportunities to acquire or partner with complementary businesses in the drug discovery outsourcing industry. By actively pursuing such opportunities, it ultimately aims to provide clients with a seamless link between drug discovery to scale up, multi-kilogram synthesis and GMP manufacture, thus capturing more value down the supply chain and proving the market with a truly vertically integrated product offering.

Operations

CBI operates on a fee-for-service basis and has integrated a number of foundation technologies to provide a broad range of capabilities to customers who otherwise must go to several different sources for their needs. The Company’s business units have a strong reputation for:

Across the Company, the business units have technical capabilities and proprietary technology platforms that differentiate them from other providers. For example:

All of CBI’s business units operate under strict Standard Operating Protocols (“SOPs”) which detail the particular technologies used to complete the work in progress. SOPs are made available to the customer upon request. In addition, CBI Services and FIL have instituted rigorous GLP reporting requirements, and have put in place the necessary features to meet all aspects of GLP compliance. The Quality Assurance Unit has enabled CBI Services and FIL to take on projects with customers who require adherence to compliance reporting. Other accreditations achieved by CBI Services and FIL include:

Marketing

CBI believes that its business units have excellent customer service reputations. Sales and business development staff employ their technical know-how by way of a consultative/collaborative selling strategy and routinely assist clients with the design of their projects and synthesis of their products. In 2007, CBI companies boasted seven of the top ten global pharmaceutical companies as clients. The reorganization of the global sales and marketing team in 2007 created an integrated service offering that provides cross-selling opportunities across our business units for clients based anywhere in the world.

CBI has embarked on an expanded marketing effort under the direction of the newly appointed Vice President of Business Development and Marketing. This will involve an increase in trade show and industry-based partnering activities, improvements to the web sites, and an enhanced e-commerce focus. CBI currently has ten full time sales and business development professionals operating in the major world markets, North America, Europe and Asia The Company has sales operations in San Francisco, Minneapolis, Raleigh-Durham, Melbourne (Australia) and Wirral (U.K.) with the corporate office in San Diego and a satellite office in St. Louis. The business units all have internal technical support professionals to provide technical quotes and field support. CBI has recently implemented an improved client relationship management system which will facilitate accurate forecasting and help pinpoint strengths and weaknesses in marketing efforts.

Intellectual Property

Each of CBI’s business units is primarily focused on fee-for-service offerings; various intellectual properties have developed that have resulted in U.S. and international patents. For example, CBI Services has patented a potential human pharmaceutical product, termed HepArrest^®. HepArrest is designed as a hospital drug for use in reversing the anti-coagulant effects of heparin. The Company has licensed HepArrest to Prism Pharmaceuticals, King of Prussia, Pennsylvania, for pre-clinical studies, leading to an Investigational New Drug application. The Company has other intellectual properties in the form of issued and pending patents, many of which underpin the various technology platforms employed by the individual business units.

CBI takes appropriate steps to protect its intellectual property rights and those of its customers. The Company’s practice is to require its employees and consultants to execute non-disclosure and proprietary rights agreements upon commencement of employment or consulting arrangements with the Company. These agreements require that all proprietary information disclosed to the individual by CBI or its customers remain confidential.

Employees

Worldwide, CBI employs 110 full-time staff in three facilities. CBI has an entrepreneurial executive management team with a wealth of scientific and commercial experience in the biotechnology and life science industries.

Partners and Partnerships

The experience of CBI’s staff coupled with its patented technology platforms and advanced laboratory facilities position the Company well for partnering with research institutions and discovery companies in drug development. CBI companies have

6

developed strategic alliances with key life science companies including Invitrogen, Genzyme, Thermo Fisher, GSK, Elan, Abbott and Schering Plough. Mimotopes’ partnership with Genzyme Pharmaceuticals has created a brand that provides a total suite of peptide products and acts as an integrated ‘one-stop-shop’ for peptide customers. In 2007, the alliance was listed as one of the top 5 leading global peptide providers in an independent analysis of the peptide industry (Bionest Partners, 2007). CBI is looking to adopt a similar partnering model with small molecule and biological cGMP manufacturers.

U.S. Government Regulation

CBI complies with existing federal, state and local laws and regulations and does not anticipate that continuing compliance will have any material effect upon the capital expenditures, earnings or competitive position. While the Company does not require government regulatory approvals to provide for current services, numerous federal, state, and local agencies, such as federal and state environmental agencies, working condition and other similar regulators, have jurisdiction to take actions that could have a material adverse effect upon its ability to do business. CBI has put in place numerous procedures and guidelines which allows it to meet accreditation requirements of federal, state, and industry specific regulatory groups. CBI anticipates that it will continue to implement and upgrade the compliance capabilities under the FDA’s GLP guidelines. The Company anticipates that eventually more of its service offerings will meet the FDA’s GMP and cCMP guidelines.

Investor Relations

The Company is committed to presentation of its capabilities in appropriate forums, such as analyst conferences and forums. Presentations made by CBI’s management at these venues are posted to CBI’s web page (www.cbi-biotech.com).

Evaluation of Disclosure Controls and Procedures

CBI maintains a system of controls and procedures designed to provide reasonable assurance as to the reliability of the financial statements and other disclosures included in this report, as well as to safeguard assets from unauthorized use or disposition. CBI evaluated the effectiveness of its disclosure controls and procedures (as defined in Rule 13a-14(c) and Rule 15a-14(c) under the Securities Exchange Act of 1934) under the supervision and with the participation of management, including the Company’s Chief Executive Officer and Vice President of Financial Operations, within 90 days prior to the filing date of this report. Based upon that evaluation, the Company’s Chief Executive Officer and Vice President of Financial Operations concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to information required to be included in the Company’s periodic Securities and Exchange Commission filings. There were no significant changes in the Company’s internal controls or in other factor that could significantly affect these controls subsequent to the date of their evaluation.

Management’s Annual Report on Internal Control Over Financial Reporting

CBI’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities and Exchange Act of 1934, as amended. CBI’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that:

(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of CBI’s assets;

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that CBI’s receipts and expenditures are being made only in accordance with the authorization of its management and directors; and

(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of CBI’s assets that could have a material effect on the financial statements.

CBI’s management assessed the effectiveness of its internal control over financial reporting as of December 31, 2007. In making this assessment, management used the framework set forth in the report entitled Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. The COSO framework summarizes each of

10

the components of a company’s internal control system, including (i) the control environment, (ii) risk assessment, (iii) control activities, (iv) information and communication, and (v) monitoring. Based on this assessment, CBI’s management believes that, as of December 31, 2007, CBI’s internal control over financing reporting is effective based on those criteria.

This annual report does not include an attestation report of CBI’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to temporary rules of the SEC that permit CBI to provide only management’s report in this annual report.
