1. TAU-CHEM Ltd. 14 YEARS OF CUSTOM SYNTHESIS & SPECIALITY CHEMICAL MANUFACTURE 1994-2008

2. Dear Sir , We would like to draw your kind attention to our company Tau-chem, Ltd. that you may recall as your Slovak business partner operating in the custom synthesis and specialty chemical manufacturing. The company celebrates its 14th anniversary these year which is not only an occasion for overall evaluation of the results achieved in the previous years but also for outlining new plans and development of the company in future. The results that have been achieved since establishment of the company are that we think can be proud of. The indicators such as the database of more than 12 000 compounds accomplished with the complete literature research, the product catalogue containing 400 compounds accomplished with the technology documentation prove the sound functionality and abilities of the company. . Within its existence the company acquired number of business partners as well as distinguished position on the market. Thinking of future, the 5 years strategy plan developed by the company owners and managers started to be pursued in 2003 and have not stopped in performing all its key ideas also this year. The strategy ideas formulate our efforts to provide continually increasing quality of services to our customers, improvement of the working environment, expansion of the reactor capacity, introduction of modern technologies including biotechnology. Another important goal is implementation of Environmental management system leading to ISO 14001 certification. I would like to underline that Slovakia were in May 2004 admitted to the EU presenting new opportunities for growth, investment and outsourcing. The EU15 has a relative abundance of capital and technology, while the new countries a relative abundance of skilled labor at low cost. The synergies between them are so obvious that further comment seem redundant. On the occasion of placing the new issue of Product list on the network and Edition 2008 of Tau-chem’s Catalogue I would like acknowledge for your enquiries, orders and at last but not at least your proper look toward Tau-Chem Ltd I believe that the former co-operation between your company and Tau-Chem Ltd take a continuation for the profit of both sites. The staff off Tau-chem’s , 3 PhD degree, 16 University degree, 4 High school degree, is ready to fulfill your order as well as the technological support are fully in disposition for manufacturing of molecules in accord with your exigency. I look forward to hearing from you. Vladimir Zvak, PhD, Director
