(Nasdaq OTC BB: TGCI) announced today that its Board of Directors, at a Special Meeting held on September 24, 2004, determined that, with regard to the Company's Series C 8% Convertible Exchangeable Preferred Stock, the conversion price into the Company's Common Stock will be reduced from $6 to $2 for a period beginning on September 24,2004, and ending on January 31, 2005, with the understanding and agreement of each converting holder of the Series C Preferred Stock that, in accepting such reduced conversion price, each such holder will be deemed to have agreed to offset the benefit of such price reduction against whatever amount of accrued dividends may be owing to such holder as of the conversion date. This step is being taken in order to encourage conversion of the few remaining outstanding shares of Series C Preferred Stock so that the continuing administrative expenses of dealing with such issue can be eliminated. As a result, a current holder of the Series C Preferred Stock will be able to convert each share of such Preferred Stock into 2.5 shares of Common Stock. Full conversion of the Series C Preferred Stock will result in the issuance of 145,250 additional shares of the Company's Common Stock.
