requested.

of Series C Preferred Stock shall have the right, at such holder's option, at
any time or from time to time to convert any of such shares into such whole
number of fully paid and nonassessable shares of Common Stock as is equal to the
quotient obtained by dividing (A) the Original Issuance Price multiplied by the
number of shares of Series C Preferred Stock being converted by (B) the Series C
Conversion Price (as defined in clause (ii) below), as last adjusted pursuant to
Section 8 hereof and then in effect, for the shares of Series C Preferred Stock
being converted, by surrender of the certificates representing the shares of

                                      -7-



Series C Preferred Stock so to be converted in the manner provided in paragraph
(b) below.

                           (ii) For the purpose of determining the interest of
                           the holders of Series C Preferred Stock in the shares
                           of Common Stock underlying such shares of Series C
                           Preferred Stock (whether for the purpose of
                           determining the holders' ratable interest in
                           dividends, distributions of Liquidation, voting
                           rights, or for the purposes of determining the
                           interest of the holders in Common Stock for the
                           purposes of the Subscription Agreement or any
                           agreements related thereto), the "Series C Conversion
                           Price" shall be deemed initially to be $0.04 and
                           shall be subject to adjustment pursuant to the
                           provisions of Section 8 hereof.

                  (b) Each holder of shares of Series C Preferred Stock may
exercise the conversion right pursuant to paragraph (a) above as to any part
hereof by delivering to the Corporation during regular business hours, at the
office of the Corporation or any transfer agent of the Corporation, the
certificate or certificates for the shares to be converted, duly endorsed or
assigned in blank or to the Corporation (if required by it), accompanied by
written notice stating that the holder elects to convert such shares and stating
the name or names (with address) in which the certificate or certificates for
the shares of Common Stock are to be issued. Conversion shall be deemed to have
been effected on the dated when the aforesaid delivery is made (the "Conversion
Date"). As promptly as practicable thereafter the Corporation shall issue and
deliver to such holder or upon the written order of such holder, to the place
designated by such holder, a certificate to which such holder is entitled and a
check or cash in receipt of any fractional interest in a share of Common Stock
as provided in paragraph (c) below. The person in whose name the certificate or
certificates for Common Stock are to be issued shall be deemed to have become a
Common Stockholder of record on the applicable Conversion Date unless the
transfer books of the Corporation are closed on that date, in which event such
person shall be deemed to have become a Common Stock holder of record on the
next succeeding date on which the transfer books are open, but the respective
Series C Conversion Price shall be that in effect on the Conversion Date. Upon
conversion of only a portion of the number of shares covered by a certificate
representing shares of Series C Preferred Stock surrendered for conversion, the
Corporation shall issue and deliver to or upon the written order of the holder
of certificate so surrendered for conversion, at the expense of the Corporation,
a new certificate covering the number of shares of Series C Preferred Stock
representing the unconverted portion of the certificate so surrendered, which
new certificate shall entitle the holder thereof to dividends on the shares of
Series C Preferred Stock represented thereby to the same extent as if the
portion of the certificate theretofore covering such unconverted shares had not
been surrendered for conversion.

                  (c) No fractional shares of Common Stock or scrip shall be
issued upon conversion of shares of Series C Preferred Stock. If more that one
share of Series C Preferred Stock shall be surrendered for conversion at any one
time by the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares of Series C Preferred Stock so surrendered. Instead of any fractional
shared of Common Stock which would otherwise be issuable upon conversion of any

                                      -8-


shares of Series C Preferred Stock the Corporation shall pay a cash adjustment
in respect of such fractional interest in an amount equal to the then fair
market value (as determined in good faith by the Board of Directors of the
Corporation) of a share of Common Stock multiplied by such fractional interest.
Fractional interest shall not be entitled to dividends, and the holders of
fractional interests shall not be entitled to dividends, and the holders of
fractional interest shall not be entitled to any rights as stockholders of the
Corporation in respect of such fractional interest.

                  (d) Upon conversion of any shares of Series C Preferred Stock,
all accrued dividends with respect to such shares shall be forfeited to the
Corporation.

                  (e) Should there be an insufficient number of shares of Common
Stock available at the time shares of the Series C Preferred Stock are offered
for conversion, the conversion period shall be extended by an amount equal to
the days elapsed since the Closing. Date.

         Section 8.   ADJUSTMENTS TO CONVERSION PRICE.

                  (a) If, at any time after the Original Issuance Date, the
number of shares of Common Stock outstanding is increased by a stock dividend
payable in shares of Common Stock or by a subdivision or split-up of shares of
Common Stock, then, following the Record Date fixed for the determination of
holders of Common Stock entitled to receive such stock dividend, subdivision of
split-up, the Conversion Price for such series shall be appropriately decreased
so that the number of shares of Common Stock issuable on conversion of each
share of Series C Preferred Stock shall be increased in proportion to such
increase in outstanding shares.

                  (b) If, at any time after the Original Issuance Date, the
number of shares or Common Stock outstanding is decreased by a combination of
the outstanding shares of Common Stock, then, following the Record Date for such
combination, the Conversion Price for such series shall be appropriately
increased so that the number of shares of Common Stock issuable on conversion of
each share of Series C Preferred Stock shall be decreased in proportion to such
decrease in outstanding shares.

                  (c) In case, at any time after the Original Issuance Date, of
any capital reorganization, or any reclassification of the stock of the
Corporation (other than a change in par value or from par value to no par value
or from no pr value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares) or the consolidation or merger
of the Corporation with or into any other person or entity (other than a
consolidation or merger in which the Corporation is the continuing corporation
and which does not result in any change in the Common Stock) or of the sale or
other disposition of all of substantially all the properties and assets of the
Corporation to any other person or entity, each share of Series C Preferred
Stock shall after such reorganization, reclassification, consolidation, merger,
sale or other disposition be convertible into the kind and number of shares of
stock or other securities or property of the Corporation or of the corporation
resulting from such consolidation or surviving such merger or to which such
properties and assets shall have been sold or otherwise disposed to which the
holder of the number of shares of Common Stock deliverable (immediately prior to
the time of conversion, me such reorganization, reclassification, consolidation,
merger, sale or other disposition) upon conversion of such shares would have
been entitled upon such reorganization, reclassification consolidation, merger,

                                      -9-


sale or other disposition. The provisions of Section 7 and this Section 8 shall
similarly apply to successive reorganizations, reclassifications,
consolidations, mergers, sales or other dispositions.

                           (i) All calculations pursuant to this Section 8 shall
                           be made to the nearest one-tenth (1/10) of a cent. No
                           adjustment of the Series C Conversion Price shall be
                           made in an amount less than one-tenth (1/10) of a
                           share, and any such lesser adjustment shall be
                           carried forward and shall be made at the time and
                           together with the next subsequent adjustment which
                           together with any adjustments so carried forward
                           shall amount to $0.10 per share or more.

                           (ii) In the event the provisions of this Section 8
                           shall require that an adjustment shall become
                           effective immediately after a Record Date for an
                           event, the Corporation may defer until the occurrence
                           of such event (i) issuing to the holder of any share
                           of Series C Preferred Stock converted after such
                           Record Date and before the occurrence of such event
                           the additional shares of capital stock issuable upon
                           such conversion by reason of the adjustment required
                           by such event over and above the shares of capital
                           stock issuable upon such conversion before giving
                           effect to such adjustment; and (ii) paying to such
                           holder any amount in cash in lieu of a fractional
                           share of capital stock pursuant to Section 7(c).

                           (iii) Whenever a Conversion Price shall be adjusted
                           as provided in this Section 8, the Corporation shall
                           forthwith file, at the office of Corporation or any
                           transfer agent designated by the Corporation for the

                           of a notice required to be mailed under the
