Stock (hereinafter referred to as the "Series "A" Preferred Stock") shall be Two
Hundred Fifty Thousand ($250,000). For purposes of this Section, all equity
securities of the corporation ranking as to dividends or distributions of assets
on liquidation, dissolution or winding up of the corporation, junior to the
Series " A" Preferred Stock, including the Common Stock, are sometimes
hereinafter referred to as "Junior Securities."

Securities, by reason of their ownership thereof, an amount equal to Two Hundred
Dollars ($200.00) per share (the "Liquidation Value") plus any accrued but
unpaid dividends on the Series " A " Preferred Stock.

before the payment or setting apart for payment of any amount for, or the
distribution of any assets of the corporation to, the holders of Junior
Securities, in connection with such liquidation, dissolution or winding up.
After the payment or the setting apart for payment to the holders of the Series
"A" Preferred Stock of the preferential amounts so payable to them, the holders
of Junior Securities shall be entitled to receive all remaining assets of the
corporation in accordance with the Certificate of Incorporation of the
corporation. If the assets or surplus funds to be distributed to the holders of
the Series " A " Preferred Stock are insufficient to permit the payment to such
holders of their full preferential amount, the assets and surplus funds legally

Preferred Stock, a quorum shall consist of a majority of the votes attributable

"Conversion Rights"):

            (a) Right to Convert. After February 25, 2001, each share of Series
" A " Preferred Stock shall be convertible, without the payment of any
additional consideration by the holder thereof and at the option of the holder
thereof, into five hundred (500) fully paid and nonassessable shares of common

declare or pay to the holders of the common stock a dividend payable in any kind
of shares of stock of the Company; or (ii) change or divide or otherwise
reclassify its common stock into the same or a different number of shares with
or without par value, or into shares of any class or classes; or (iii)
consolidate or merge with, or transfer its property as an entirety or
substantially as an entirety to, any other corporation; then, upon subsequent
exercise of this conversion, the holder thereof shall receive, in addition to or
in substitution for the shares of common stock to which he would otherwise be
entitled upon such exercise, such additional shares of stock of the Company, or
such reclassified shares of stock of the Company, or such shares of the
securities or property of the Company resulting from such consolidation or
merger or transfer, which he would have been entitled to receive had he
exercised this conversion prior to the happening of any of the foregoing events.

            (b) Mechanics of Conversion. Holders of Series "A" Preferred Stock
may exercise their conversion rights after February 15,2001. Before any holder
of Series "A" Preferred Stock shall be entitled to convert the same into full

therefore, duly endorsed, at the office of the corporation or of any transfer
agent for the Series " A " Preferred Stock, and shall give written notice to the
corporation at such office that he elects to convert the same and shall state
therein his name or the name or names of his nominees in which he wishes the
certificate or certificates for shares of common stock to be issued.

            (c) The corporation shall, as soon as practicable thereafter, issue
and deliver at such office to such holder of Series " A " Preferred Stock, or to
his nominee or nominees, a certificate or certificates for the number of shares
of common stock to which he shall be entitled as aforesaid, together with cash
in payment of any accrued unpaid dividends on the shares of Series " A "
Preferred Stock converted through the date of conversion, and a certificate or
certificates for such Series " A " Preferred Stock as were represented by the
certificates surrendered and not converted. Such conversion shall be deemed to
have been immediately prior to the close of business on the date of such
surrender of the shares of Common Stock issuable upon conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common stock on such date.

Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the corporation but will at
all times in good faith assist in the carrying out of all the provisions of this
Section 6 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the holders of the
Series "A" Preferred Stock against impairment.

            (e) Notices of Record Date. In the event of any taking by the
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend ( other than a cash dividend which is the same as cash dividends paid
in previous quarters) or other distribution, the corporation shall mail to each
holder of Series " A" Preferred Stock at least ten (10) days prior to the date
specified herein, a notice specifying the date on which any such record is to be
taken for the purpose of such dividend or distribution.

            (f) Common Stock Reserved. The corporation shall reserve and keep
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect conversion of
the Series " A " Preferred Stock.
