Company is legally permitted to make the payment of such dividends and whether or not such dividends are declared, and shall be payable when, as and if declared by the Board. All dividends on the
Series&nbsp;B Preferred shall accrue on a daily basis from the Issue Date whether or not there are (at the time such dividend accrues or becomes payable or at any other time) profits, surplus or
other funds of the Corporation legally available for the payment of dividends. Neither conversion on or after April&nbsp;1, 2005 nor redemption of the Series&nbsp;B Preferred on or after
April&nbsp;1, 2005 shall affect any holder's right to receive any accrued but unpaid dividends on such Series&nbsp;B Preferred. Notwithstanding any other provision herein, no dividends shall be

Dividend Payment Date shall accrue additional dividends and all such accrued and unpaid dividends shall compound on a quarterly basis at a rate per annum equal to 12% (the
"</FONT><FONT SIZE=2><B><I>Default Rate</I></B></FONT><FONT SIZE=2>"). Except as provided in the preceding sentence, (i)&nbsp;no interest, or sum of money in lieu of interest, shall be payable in respect
of any dividend payment or payments on the Series&nbsp;B Preferred that are in arrears, and (ii)&nbsp;the dividend rate specified in Section&nbsp;3(a) shall continue in effect. </FONT></P>

the close of business on the tenth Business Day immediately preceding the respective Dividend Payment Date or on such other record date as may be fixed by the Board in advance of a Dividend Payment
Date, provided that no such record date shall be less than ten nor more than 60 calendar days preceding such Dividend Payment Date. Dividends in arrears may be declared and paid at any time to holders
of record on a date not more than 60 calendar days preceding the payment date as may be fixed by the Board. Dividends paid on shares of Series&nbsp;B Preferred in an amount less than the total
amount of such dividends at the time payable shall be allocated pro rata on a share by share basis among all shares outstanding. "</FONT><FONT SIZE=2><B><I>Business Day</I></B></FONT><FONT SIZE=2>" means
any day other than a Saturday, Sunday or a day on which banking institutions in New York, New York are authorized or obligated by law or executive order to close. </FONT></P>

thereof (or any money be paid to a sinking fund or otherwise set apart for the purchase or redemption of any such Junior Securities), without the prior consent of the holders of a majority of the

assets of the Corporation to the holders of any other class or series of shares, the amount of $77.50 per share of Series&nbsp;B Preferred (the "</FONT><FONT SIZE=2><B><I>Initial Liquidation

the extent the available assets are insufficient to fully satisfy the Liquidation Preference, then the holders of the Series&nbsp;B Preferred shall share ratably in such distribution in the
proportion that each holder's shares bears to the total number of shares of Series&nbsp;B Preferred outstanding. No payment on account of any such liquidation, dissolution or winding up of the

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><I>Automatic Conversion.</I></FONT><FONT SIZE=2> The Series&nbsp;B Preferred shall automatically convert into Common Stock on the day (the
"</FONT><FONT SIZE=2><B><I>Conversion Date</I></B></FONT><FONT SIZE=2>") immediately following the expiration of the twenty calendar day period set forth in Rule&nbsp;14c-2(b) under the
Exchange Act, such period commencing on the distribution to the Corporation's stockholders in accordance Regulation&nbsp;14C promulgated under the Exchange Act of an Information Statement on
Schedule&nbsp;14C filed by the Corporation with the Securities and Exchange Commission relating to the issuance of Common Stock in connection with the conversion of the Series&nbsp;B Preferred.
Each share of Series&nbsp;B Preferred shall be convertible into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing (i)&nbsp;the
Liquidation Preference of the Series&nbsp;B Preferred determined pursuant to Section&nbsp;4, by (ii)&nbsp;the Conversion Price determined as hereinafter provided in effect on the Conversion
Date. Each share of Series&nbsp;B Preferred shall thus at the date of original issuance be convertible into ten shares of Common Stock, subject to adjustment as set forth herein. Upon the automatic
conversion of the Series&nbsp;B Preferred, (i)&nbsp;each holder shall be deemed to own the number of shares of Common Stock into which the holder's Series&nbsp;B Preferred is converted and
(ii)&nbsp;the Corporation shall pay in cash all accrued and unpaid dividends, if any, through the Conversion Date. Promptly thereafter the holder shall surrender the certificate or certificates
representing the Series&nbsp;B Preferred which were converted at the office of the Corporation or of the transfer agent for such shares, or at such other place designated by the Corporation. Such
surrender may be made by registered mail with return receipt requested, properly insured, by hand or by overnight courier. The Corporation shall, promptly upon receipt of such certificates
representing the Series&nbsp;B Preferred shares which have been converted, deliver to such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall
be entitled. At the close of business on the Conversion Date, each holder shall be deemed to be the beneficial owner of the shares of Common Stock, and the Series&nbsp;B Preferred theretofore held
by such holder shall no longer be outstanding. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><I>Determination of Conversion Price</I></FONT><FONT SIZE=2>. The Conversion Price (the "</FONT><FONT SIZE=2><B><I>Conversion
Price</I></B></FONT><FONT SIZE=2>") shall be $7.75. If the Corporation at any time or from time to time makes, issues, declares, pays or fixes a record date for the determination of holders entitled to
receive any dividend or other distribution payable of shares of Common Stock in Common Stock or other securities of the Corporation or any of its subsidiaries or in rights to acquire Common Stock or
other securities of the Corporation or any of its subsidiaries, or shall effect a stock split or reverse stock split, or a combination, consolidation or reclassification of the Common Stock, then in
each such event the Conversion Price shall be proportionately decreased or increased, as appropriate, to give effect to such event, such that upon any conversion after any such event, a holder of
Series&nbsp;B Preferred shall be entitled to receive the number and class of any securities of the Corporation or other assets which the holder would have received had the Series&nbsp;B Preferred
been converted into Common Stock immediately before the event. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><I>Certificates as to Adjustments</I></FONT><FONT SIZE=2>. Upon the occurrence of any adjustment or readjustment of the Conversion Price pursuant to
Section&nbsp;5(b), the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and the principal financial officer of the Corporation
shall verify such computation and prepare and furnish to each holder of Series&nbsp;B Preferred a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series&nbsp;B Preferred, furnish or cause to be furnished to such holder a like
certificate prepared by the Corporation setting forth (i)&nbsp;such adjustments and readjustments and (ii)&nbsp;the number of other securities and the amount, if any, of other property which at
the time would be received upon the conversion of Series&nbsp;B Preferred with respect to each share of Common Stock received upon such conversion. </FONT></P>

determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any security or right convertible into or entitling the holder thereof to
receive additional shares of Common Stock, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other
right, the Corporation shall mail to each holder of Series&nbsp;B Preferred at least ten days prior to the date specified therein, a notice specifying the date on which any such record is to be
taken for the purpose of such dividend, distribution, security or right and the amount and character of such dividend, distribution, security or right. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><I>Issue Taxes</I></FONT><FONT SIZE=2>. The Corporation shall pay any and all issue and other taxes, excluding any income, franchise or similar
taxes, that may be payable in respect of any issue or delivery of shares of Common Stock on conversion of shares of Series&nbsp;B Preferred; provided, however, that the Corporation shall not be
obligated to pay any transfer taxes resulting from any transfer requested by any holder in connection with any such conversion. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><I>Reservation of Stock Issuable Upon Conversion</I></FONT><FONT SIZE=2>. The Corporation shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series&nbsp;B Preferred, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding shares of the Series&nbsp;B Preferred, and if at any time the number of authorized but unissued shares of Common Stock
shall not be sufficient to effect the conversion of all then outstanding shares of the Series&nbsp;B Preferred, the Corporation will take such corporate action as may, in the opinion of its counsel,
be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose, including, without limitation, engaging in best efforts to
obtain the requisite stockholder approval. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)&nbsp;&nbsp;&nbsp;</FONT><FONT
SIZE=2><I>Fractional Shares</I></FONT><FONT SIZE=2>. No fractional shares shall be issued upon the conversion of any share or shares of Series&nbsp;B
Preferred. All shares of Common Stock (including fractions thereof) issuable upon conversion of more than one share of Series&nbsp;B Preferred by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance of any fractional share. If, after the aforementioned aggregation, the conversion would result in the issuance of a fraction of a share
of Common Stock, in lieu of issuing any fractional share, the fraction shall be rounded up or down to the nearest whole number of shares. </FONT></P>

or any consolidation or merger of the Corporation with or into any other corporation or corporations or a sale of all or substantially all of the assets of the Corporation to any other person, and
such transaction is not treated as a liquidation, dissolution or winding up as provided in Section&nbsp;4, then, as part of such reorganization, consolidation, merger or sale, provision shall be
made so that each share of Series&nbsp;B Preferred shall thereafter be convertible into the number of shares of stock or other securities or property (including cash) to which a holder of the number
of shares of Common Stock deliverable upon conversion of such share of Series&nbsp;B Preferred would have been entitled upon the record date of (or date of, if no record date is fixed) such event
and, in any case, appropriate adjustment (as determined by the Board of Directors) shall be made in the application of the provisions herein set forth with respect to the rights and interest
thereafter of the holders of the Series&nbsp;B Preferred, to the end that the provisions set forth herein shall thereafter be applicable, as nearly as equivalent as is practicable, in relation to
any shares of stock or the securities or property (including cash) thereafter deliverable upon the conversion of the shares of Series&nbsp;B Preferred. </FONT></P>
