On December 1, 2005, Zoltek Companies, Inc. (the "Registrant") announced that it had completed the private placement of $15 million aggregate principal amount of 7.5% Senior Convertible Notes (the "Notes") pursuant to the terms of its previously announced Loan and Warrant Agreement, dated as of September 29, 2005 (the "Loan Agreement"), among the Registrant, the lenders parties thereto ("Lenders"). As previously reported by the Registrant in its Current Report dated September 29, 2005, under the Loan Agreement the Registrant may issue up to $50 million principal amount of senior convertible notes in up to four tranches, with the first tranche being for $5 million principal amount of Notes, the second tranche for up to $15 million principal amount of Notes, the third tranche for up to $20 million principal amount of Notes, and the fourth tranche for up to $10 million principal amount of Notes. The closing of the funding of the first tranche was completed on September 30, 2005 and the closing of the second tranche was completed on November 30, 2005. A copy of the Loan Agreement is incorporated by reference in this report as Exhibit 4.1. The Notes, the form of which is incorporated by reference in this report as Exhibit 4.2, are convertible into shares of Common Stock. The initial conversion price of the Notes is $12.50 (subject to adjustment). The Notes bear interest at the rate of 7.5% per annum, payable quarterly, and are due and payable upon the expiration of their 42-month term. The interest on the Notes may be paid in cash or, at the Registrant's option, in Common Stock if certain conditions are satisfied as set forth in the Notes. If the Company chooses to pay the interest in Common Stock, the price will be based on 90% of the average of the daily volume weighted average price for the 20 days prior to the interest payment date. The Notes will be secured by a pledge of certain real property and fixed assets associated with the operations of Zoltek Rt., the Registrant's Hungarian subsidiary. Pursuant to the Loan Agreement, the Company agreed to issue to the Lenders warrants to purchase 420,000 additional shares of Common Stock, representing 35% of the number of shares into which the Notes are convertible (the "Warrants"). The Warrants, the form of which are incorporated by reference in this report as Exhibit 4.3, have five-year terms. The exercise price of the Warrants issued in the second tranche is $14.50 (subject to adjustment). The conversion prices of the Notes and the exercise prices of the Warrants are both subject to adjustment under certain circumstances, as set forth in the Notes and the Warrants. The number of shares of Common Stock issuable under the Notes and the Warrants are subject to the occurrences of certain events described therein such as the declaration by the Registrant of a stock dividend, a subdivision or combination of its outstanding shares of Common Stock, a reclassification of the outstanding securities of the Registrant (including due to reorganization of the Registrant itself) or the issuance of common equity securities at a price less than the applicable conversion or exercise price. All of the Lenders are "accredited investors," as defined in Rule 501 of Regulation D under the Securities Act of 1933, as amended (the "Securities Act"), and the securities offered and sold in the private placement have not been registered under the Securities Act and were sold without registration in reliance upon the exemption from securities registration under both Rule 506 of Regulation D and Section 4(2) of the Securities Act. The Registrant has entered into a Registration Rights Agreement with the Lenders, a copy of which is incorporated by reference in this report as Exhibit 4.4 ("Registration Rights Agreement"), pursuant to which the Lenders shall have the right to demand registration of the Common Stock and to participate in certain subsequent offerings of securities by the Registrant or other shareholders. The foregoing summary is qualified in its entirety by the Loan Agreement, Notes, Warrants, and the Registration Rights Agreement, and should be read in conjunction with, the copies of such documents incorporated by reference in this report as exhibits. On December 1, 2005, the Registrant issued a press release announcing that it had completed the funding of the second tranche under the Loan Agreement in the amount of $15.0 million.
