ADDITIONAL INFORMATION On December 29, 2000, the Company filed a Certificate of Merger with the Secretary of State of the State of Delaware, pursuant to which Acquisition, a company formed by IIIX for the sole purpose of effecting the merger, was merged with and into the Company, with the Company as the surviving corporation (the "Merger"). The Merger became effective as of December 31, 2000, at which time (i) each of the outstanding shares of Common Stock of the Company (other than shares held by dissenting stockholders and the Company) was automatically converted into the right to receive $2.85 in cash, without interest, upon surrender and acceptance of the certificate for such share to the Company's exchange agent, (ii) each of the outstanding shares of Common Stock of the Company held by the Company or its subsidiaries and constituting treasury stock was canceled without consideration, (iii) each share of Acquisition issued and outstanding immediately before the Effective Time was converted into and became one share of common stock of the surviving corporation; and (iv) the separate corporate existence of Acquisition ceased. As a result of the Merger, the Common Stock of the Company ceased to trade on The Nasdaq National Market System and became eligible for delisting from The Nasdaq National Market System and termination of registration pursuant to Section 12(g)(4) and 12(h)(3) of the Exchange Act. Accordingly, on January 2, 2001, the Company filed a Certification and Notice of Termination of Registration on Form 15 with the Securities and Exchange Commission. -3- After due inquiry and to the best of my knowledge and belief, I certify that the information in this statement is true, complete and correct.
