Our Technology Bayer has a modern chemical and biological production infrastructure. The production and development facilities are located in four different sites: Bergkamen, Wuppertal and Berlin in Germany, and Orizaba in Mexico. The sites are regularly inspected by local and foreign governmental authorities such as the FDA and the EMA, as well as by customers. Internal and external auditors audit the sites according to internal and international health, safety and environmental standards (e.g. ISO 14001, 45001). All production sites meet the highest GMP and HSE standards. Each of these sites offers specific production capabilities. Our technology includes: Fermentation Our Know-How Selected Chemical and Microbiological Reactions Biotransformations (e.g. steroids) Hydroxylation Reduction Oxidation Secondary metabolites /natural products Biopharmaceuticals Cultivation of bacteria, fungi and yeasts Epoxidation Halogenation Hydrogenation Hydroxylation Bromination Fluorination Iodination Chlorination Our Technology Large-scale fermentation and recovery technology Leading technology for production of steroid key intermediates (phytosterols > AD, ADD) Microbiological Reactions Organometallic Reactions Oxidation Reduction Microbiological Oxidation Microbiological Reduction Ethinylation Grignard Jones Oppenauer Swern Birch FDA-approved full GMP production Scale-up capacities from 5 l to 50 m 3 Micronization of APIs Special Reactions Aromatization Cyclopropanation Reaction with Cyanides Ringold Vilsmeier Product groups High-potency APIs Hormones Narcotics Other APIs Excipients FDA-approved full GMP production ///////// 8 ///

Production Sites Production Site Bergkamen / Germany The US- and EU-approved Supply Center Bergkamen is our biggest API production site. APIs and intermediates from Bergkamen are used for our in-house production of drugs ready for sale. They are also sold in bulk to other pharmaceutical companies. At Bergkamen, 1,500 employees produce APIs and their intermediates according to the highest levels of quality. This is achieved by combining microbial fermentation and chemical transformation in an optimum way. Bergkamen is internationally recognized for its production of steroid hormones. The Bergkamen site is validated and externally certifi ed according to the highest health, safety and environmental standards, such as EMAS (EU Eco-Management and Audit Scheme), ISO 14001 (Environmental Management), OHSAS 18001 (Occupational Health and Safety Management) as well as ISO 50001 (Energy Management).

Production Site Wuppertal / Germany This site is home to the company and stands for its long tradition: Bayer was founded in 1863 in Elberfeld, which is now part of the city of Wuppertal. At present, the site houses modern research and development as well as production facilities for our Pharmaceuticals division. The Wuppertal site nowadays comprises two different locations: the production facilities near the river Wupper, and the center for research and development in Aprath. The production has an annual output of more than 1,000 tons of APIs. At the research and development center, staff members work on substances used in cardiology and oncology. The biological sewage treatment plant is equipped with modern technology and guarantees the safety and quality of the environment and water. The Wuppertal site employs a total of 3,500 staff members in the areas of research, development and production. They create and manufacture new and innovative APIs for the treatment of cardiovascular and blood-related diseases, cancer and other disorders such as diabetes. The Elberfeld site complies with the highest health, safety and environmental standards and is certified according to ISO 14001, OHSAS 18001 as well as ISO 50001. The site is US and EU approved. Products for Pharma Chemicals: Acarbose, Ciprofloxacin, Moxifloxacin Hydrochloride, Nifedipine Micronization Plant Berlin / Germany In Bayer AG s FDA- and EU-approved drug substance finishing unit in Berlin-Charlotten burg, we sieve, homogenize and micronize high-speciality ingredients. Identical standards apply at all of Bayer's micronization sites. The micronization plant consists of several independent milling compartments, each of which has its own milling room, observation room, equipment cleaning room, and weighing room. The modular construction of these facilities is a pioneering achievement. The milling and observation rooms are separated by a decontamination chamber. To avoid cross-contamination, each module may only contain one substance. After the processing of one substance has been completed, the entire equipment and all rooms within the module are cleaned in strict accordance with cgmp guidelines like in all other production plants at Bayer. Micronization of APIs is performed for high-potency APIs such as hormones, narcotics and others, as well as excipients. The Charlottenburg site has also implemented the highest health, safety and environ mental standards and is certified according to ISO 14001, OHSAS 18001 as well as ISO 50001. ///////// 10 ///

Production Site Orizaba / Mexico The Orizaba API site is Bayer AG s second major chemical facility for hormone and steroid production, founded in 1963. A broad range of substances for bulk sales and for Bayer AG s own pharmaceutical specialties has been developed and is produced here: Estrogens: 17α-Estradiol, Estradiol Enanthate Progestogens: Danazol, Dihydroxyprogesterone Acetophenide (Algestone Acetophenide), Progesterone Androgens: Testosterone, Testosterone Enanthate, Testosterone Undecanoate, Prasterone Enanthate Intermediates: Dehydroepiandrosterone (Prasterone), Mestanolone 1-Dehydrotestosterone (Boldenone), Ethisterone Like Bergkamen and Wuppertal, the Supply Center in Orizaba, Veracruz (Mexico) is FDA approved.
