THERMODYNETICS, INC., WINDSOR, CT (TDYT:OTCBB)

Thermodynetics, Inc. plans to admit the shares of a United Kingdom (UK) registered subsidiary to trading on the London Stock Exchange’s AIM market.

Thermodynetics has engaged Dawnay, Day Corporate Finance Limited and Dawnay, Day Townsley to act as its Nominated Advisor and Broker to the UK subsidiary respectively, and has engaged other advisors in London, to advise on the proposed public offering of its UK subsidiary and the admission of its issued share capital to trading on AIM. It is intended that the UK subsidiary will be the holding company for Thermodynetics’ operating subsidiary, Turbotec Products, Inc.

Shares in the new UK company, which has been formed, will be offered for subscription and sale to non-US investors prior to the admission of the new company’s issued share capital to trading on AIM. The public offering is expected to be completed in April 2006 and to raise approximately $7 million after all expenses. The net proceeds of the issue of new shares will be used to reduce debt, for expansion and for working capital for Turbotec Products Inc.

There can, of course, be no assurance that the offering and admission will proceed as the process is subject to finalization and to market conditions and the offering will not be underwritten.
