                           stockholder's name on the stock transfer records of
                           the Corporation. Upon such automatic conversion, the
                           outstanding shares of the Series A Preferred Stock
                           will be converted automatically without any further
                           action by the holders of such shares and whether or
                           not the certificates representing such shares are
                           surrendered to the Corporation or the transfer agent,
                           if any, designated by the Corporation; provided,
                           however, that the Corporation shall not be obligated
                           to issue certificates evidencing the shares of Common
                           Stock issuable upon such conversion unless the
                           certificates evidencing such shares of the Series A
                           Preferred Stock are either delivered to the
                           Corporation or its transfer agent as provided below,
                           or the holder notifies the Corporation or its
                           transfer agent that such certificates have been lost,
                           stolen or destroyed and executes an agreement and an
                           affidavit of loss satisfactory to the Corporation to
                           indemnify the Corporation (with surety if requested)
                           from any loss incurred by it in connection therewith.
                           Upon the occurrence of such automatic conversion of
                           the Series A Preferred Stock, the holders of the
                           Series A Preferred Stock shall surrender the
                           certificate or certificates, or the agreement and
                           affidavit of loss, representing such shares to the
                           Corporation at its principal office or to its
                           transfer agent As promptly as practicable after the
                           automatic conversion, the Corporation shall issue and
                           deliver to the holder or holders of the shares of the
                           Series A Preferred Stock being automatically
                           converted: (i) such certificate or certificates as
                           the holder or holders may request for the number of
                           whole shares of Common Stock into which the shares of
                           the Series A Preferred Stock surrendered were
                           convertible on the date on which such automatic
                           conversion occurred; (ii) cash, as provided in
                           Section 4(d), in respect of any declared and unpaid
                           dividends on the shares of the Series A Preferred

                                       7


                           Stock being automatically converted and (iii) cash,
                           as provided in Section 4(h), in respect of any
                           fraction of a share of Common Stock otherwise
                           issuable upon such automatic conversion.

                  (i)      Cash in Lieu of Fractional Shares. No fractional
                           shares of Common Stock or scrip representing
                           fractional shares shall be issued upon the conversion
                           of shares of the Series A Preferred Stock. Instead of
                           any fractional shares of Common Stock which would
                           otherwise be issuable upon conversion of the Series A
                           Preferred Stock, the Corporation shall pay to the
                           holder of the shares of the Series A Preferred Stock
                           which were converted a cash adjustment in respect of
                           such fractional shares in an amount equal to the same
                           fraction of the fair market value of one (1) share of
                           Common Stock (as determined in good faith by the
                           Board of Directors) at the close of business on the
                           Conversion Date or the date of automatic conversion.
                           The determination as to whether or not to make any
                           cash payment in lieu of the issuance of fractional
                           shares shall be based upon the total number of shares
                           of the Series A Preferred Stock being converted at
                           any one time by any holder thereof; and not upon each
                           share of the Series A Preferred Stock being
                           converted.

                  (j)      Partial Conversion. In the event that some but not
                           all of the shares of the Series A Preferred Stock
                           represented by a certificate or certificates
                           surrendered by a holder are converted, the
                           Corporation shall execute and deliver to or on the
                           order of the holder, at the expense of the
                           Corporation, a new certificate representing (he
                           number of shares of The Series A Preferred Stock

                           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 A Preferred Stock, 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 A Preferred
                           Stock, 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 A Preferred Stock,
                           the Corporation shall take such corporate action,
                           subject to the terms of its Certificate of
                           Incorporation and applicable law, as may be necessary
                           to increase its authorized but unissued shares of
                           Common Stock at least to such number of shares as
                           shall be sufficient for such purpose.

                  (l)      Issue Tax. The issuance of certificates for shares of
                           Common Stock upon conversion of shares of the Series
                           A Preferred Stock shall be made without charge to the
                           holders thereof for any issuance tax in respect
                           thereof, provided that the Corporation shall not be
                           required to pay any tax which may be payable in
                           respect of any transfer involved in the issuance and

                                       8


                           delivery of any certificate in a name other than that
                           of the holder of shares of the Series A Preferred
                           Stock which is being converted.

                  (m)      Closing of Books. The Corporation shall at no time
                           close its transfer books against the transfer of
                           shares of the Series A Preferred Stock or of any
                           shares of Common Stock issued or issuable upon the
                           conversion of the Series A Preferred Stock in any
                           manner which interferes with the timely conversion
                           of shares of the Series A Preferred Stock, except' as
                           may otherwise be required to comply with applicable
                           securities laws.

                  holders of shares of the Series A Preferred Stock shall not be
                  entitled to any redemption rights.

         6.       Transferability. The holders of shares of the Series A
                  Preferred Stock shall not be entitled to sell, assign or
                  otherwise transfer the shares of the Series A Preferred Stock
                  Series to any person or entity other than NRG Energy, Inc. or
