As of the date hereof, the Company has 10,000,000 shares of Common Stock authorized, of which 3,444,641 shares are issued and outstanding. In addition thereto, the Company has authorized 1,000,000 shares of blank check preferred stock, par value $1.00 per share, of which no shares have been issued. 2. As of the date hereof, the Company has outstanding options granted, in each case, to employees, officers or directors of the Company for a total of 975,500 shares of the Company's common stock. Section 2.7 - Financial Information and SEC Reports - --------------------------------------------------- Information about the Company's financial statements has been fully disclosed in the reports it has filed under the Securities Exchange Act of 1934. Section 2.8 - Litigation - ------------------------ Management of the Company is not aware of any litigation against the Company except for routine litigation against the Company or litigation referenced in the Company's reports filed under the Securities Exchange Act of 1934, as amended. Section 2.11 - Subsidiaries - --------------------------- The Company has the following subsidiaries: * Temtex Fireplace Products, Inc., a Texas corporation, wholly owned by the Company. * Temtex International, Inc., a Texas corporation, wholly owned by Temco Fireplace Products, Inc. * Temcomex, S.A. DE C.V., a Mexican corporation jointly owned by Temco Fireplace Products, Inc. and Temtex International. Section 2.16 - Insurance - ------------------------ None -1- Additional Disclosures - ---------------------- 1. The Company is a party to that Consulting Services Agreement, dated July 27, 2001 by and between the Company and ECDI Capital Corp. (the "Consulting Agreement"). Pursuant to the Consulting Agreement, among other things, ECDI was to assist the Company in its efforts to effect a "Sale" of the business of the Company (as "Sale" is defined in the Consulting Agreement") in exchange for a consulting fee of not less than $250,000 (the "Consulting Fee"). While ECDI was not successful in its attempts to effect a Sale of the Company, it is possible that ECDI may claim that the transactions contemplated by the Note Purchase Agreement and the Secured Term Note (and all ancillary agreements thereto) meet the definition of Sale under the Consulting Agreement and attempt to collect the Consulting Fee from the Company. While the Company's management does not believe the contemplated transactions constitute a sale under the Consulting Agreement, it is impossible to determine if EDCI will make such a claim, and if so whether ECDI would be successful in pressing such a claim. Should the Company ultimately be compelled to make payment of the Consulting Fee, it would likely have a material adverse impact on its financial position and results of operation. 2. The Company has previously considered, and may in the future consider, becoming a private company under the Securities Exchange Act of 1934, as amended. No assurances, however, can be given that: * such a transaction is feasible; * if feasible, that such a transaction would benefit the Company or the Investors; * whether the Company could maintain its net operating loss carryforwards after such a transaction. To the extent the Company should elect to engage in a going-private transaction, there would be no public market for the Conversion Shares thereafter. 3. We may need additional working capital after this transaction to remain operational. No assurances can be given that the funds received in connection with the contemplated transactions will be sufficient for any period of time in the future. To the extent we need additional working capital, we may not be able to get it on terms acceptable to the Company, or at all. 4. We are in the process of moving our Manchester, Tennessee operations to Mexicali, Mexico. The required reduction in force at our Manchester facility may give rise to certain litigation which could have a negative impact on our operations. In addition, the move requires the transfer of a significant amount of equipment and materials from Manchester to Mexicali. As the move has not been completed the risks associated with the completion of the move, including delayed operations due to damaged equipment, are currently unknown. Likewise, the level of performance of the operations at the Mexicali location is currently unknown. Losses attributed to the move, disruption in production, or difficulties with a new and unproven workforce all could have a negative effect on our operations and the return on your investment in Temtex. -2- 5. The residential housing market has experienced a sustained period of growth in new construction, which has been an advantage to us. Even with this advantage, we have experienced a period of difficulty and instability, requiring additional capital to fund our operations. Historically, such performance is followed by an industry downturn. As a major producer of metal fireplace products used in the residential construction markets, a downturn in the housing market would have a significant negative impact on our performance leading to an even greater drain on capital resources than recently experienced. 6. No assurances can be given that the Company will be able to continue as a going concern. -3-
