         "4B. Redemption Payments.  For each Share which is to be redeemed under

         pay  to  the  holder  thereof(upon  surrender  by  such  holder  at the
         Company's principal office of the certificate  representing such Share)
         an  amount  in  cash  in  immediately  available  funds  equal  to  the

         (e) Section 4H of the  Certificate of Designations is hereby deleted in

         "4H.  Change of  Control.  If a Change of Control  has  occurred or the
         Company  obtains  knowledge  that a Change of  Control is  proposed  to
         occur,  the Company shall give prompt  written notice of such Change of
         Control  describing in reasonable detail the material terms and date of
         consummation  thereof to each  holder of  Preferred  Stock,  but in any
         event  such  notice  shall not be given  later than five days after the
         occurrence  of such Change of Control,  and the Company shall give each
         holder of Preferred  Stock prompt written notice of any material change
         in the terms or timing of such  transaction.  Any  holder of  Preferred
         Stock may,  at its  option  convert  all or a portion of such  holder's
         Preferred  Stock  (including  any fraction of a Share) into a number of
         shares of Conversion  Stock computed by dividing (A) the sum of (x) the
         product obtained by multiplying the number of Shares to be converted by
         $100 and (y) all  accrued  and unpaid  dividends,  by (B) the Change of
         Control Conversion Price.

         For purposes hereof,  "Change of Control  Conversion  Price" shall mean
         the lower of (1) the lower of (a) the Maximum  Conversion Price and (b)
         90% of the Market  Price of a share of Common Stock on the Business Day
         immediately  preceding the public announcement of the Change of Control
         transaction and (2) the lower of (c) the Maximum  Conversion  Price and
         (d) the Market  Price of a share of Common  Stock on the  Business  Day
         immediately  following such public announcement.  Any holder who elects
         to convert such holder's  Preferred Stock may immediately  prior to the
         consummation  of the Change of  Control  transaction  convert  all or a
         portion of such holder's  Preferred Stock  (including any fraction of a
         Share) into the number of shares of Conversion  Stock calculated as set
         forth above.

                                      -2-


                           Upon receipt of a notice of  conversion,  the Company
         shall effect the immediate  conversion into Common Stock (if the holder
         has requested  conversion into Common Stock). If any proposed Change of
         Control  does not occur,  all  requests for  conversion  in  connection
         therewith  shall be  automatically  rescinded,  or if there  has been a
         material  change in the terms or the  timing  of the  transaction,  any
         holder of  Preferred  Stock  may  rescind  such  holder's  request  for
         conversion by giving written notice of such rescission to the Company.

                           The term  "Change  of  Control"  means  (a) any sale,
         transfer or issuance or series of sales,  transfers and/or issuances of
         Common Stock by the Company or any holders thereof which results in any
         Person  or group of  Persons  (as the term  "group"  is used  under the
         Exchange  Act),  beneficially  owning  (as  such  term  is  used in the
         Exchange Act) more than 50% of the Common Stock outstanding at the time
         of such sale, transfer or issuance or series of sales, transfers and/or
         issuances,  (b) any sale or  transfer of more than 50% of the assets of
         the Company and its  Subsidiaries  on a  consolidated  basis  (measured
         either by book value in accordance with generally  accepted  accounting
         principles  consistently  applied or by fair market value determined in
         the  reasonable  good faith  judgment of the Board of Directors) in any
         transaction or series of transactions (other than sales in the ordinary
         course  of  business  and  excluding  the  sale of the  synthetic  fuel
         facilities set forth on Schedule 8.1(e) of the Purchase Agreement), (c)
         any merger or consolidation to which the Company is a party, except for
         a merger in which the Company is the  surviving  Company,  the terms of
         the  Preferred  Stock are not  changed and the  Preferred  Stock is not
         exchanged  for cash,  securities  or other  property,  and after giving
         effect to such merger, the holders of the Company's outstanding capital
         stock  possessing  a  majority  of the  voting  power  (under  ordinary
         circumstances)   to  elect  a  majority  of  the  Board  of   Directors
         immediately  prior to the merger  shall  continue to own the  Company's
         outstanding  capital stock  possessing the voting power (under ordinary
         circumstances)  to elect a majority of the Board of  Directors  and (d)
         any Organic Change."

         (f) Section 6E of the  Certificate of Designations is hereby amended by
deleting  the first  sentence  therein  and  replacing  such  sentence  with the
following new sentence:

         "Any recapitalization, reorganization, reclassification, consolidation,
         merger,  sale of all or  substantially  all of the Company's  assets or
         other transaction, in each case which is effected in such a manner that
         all the  holders  of  Common  Stock are  entitled  to  receive  (either

         with respect to or in exchange for Common Stock,  is referred to herein
         as an "Organic Change".

         the  Preferred  Stock  following  the  giving  of  notice  pursuant  to
         paragraph 4C, whether or not such payment is legally  permissible or is
         prohibited by any agreement to which the Company is subject;

         (iii) the Company breaches or otherwise fails to perform or observe any
         material  provision  contained in this Certificate of Designations,  in
         the Purchase  Agreement or in the Related  Documents (as defined in the
         Purchase  Agreement),  as each such document may be amended or modified
         from time to time,  and (other  than with  respect  to  Section  8.1 or
         8.2(m) of the Purchase  Agreement,  Section 1(f)(i) of the Registration
         Rights  Agreement  or  paragraph 6 hereof,  the breach of or failure to
         perform which shall result in an immediate Event of Noncompliance) such
         failure is not cured  within  fifteen  (15) days  after the  occurrence

Designations  are  hereby  deleted  in  their  entirety  and  replaced  with the

         any holder of any shares of Preferred Stock then outstanding may demand

         provision  contained  herein,  the  immediate  conversion of all or any

         dividend rate on the Preferred Stock (including any Preferred Stock not
         converted  pursuant to clause (a) above) shall increase  immediately by
         an increment  of two  percentage  points.  Any increase of the dividend
         rate resulting from the operation of this subparagraph  shall terminate
         as of  the  close  of  business  on the  date  on  which  no  Event  of
         Noncompliance  exists,  subject to subsequent increases in the event of
         the occurrence of a subsequent Event of Noncompliance  pursuant to this
         paragraph. The Company shall give prompt written notice of any holder's
         election for  immediate  conversion  to the other  holders of Preferred
         Stock (but in any event  within five days after  receipt of the initial
         demand for conversion), and each such other holder may demand immediate
