                                  SIMCALA, INC.


         The undersigned, being all of the Directors of SIMCALA, Inc. (the
"Corporation"), a corporation organized and existing under the General
Corporation Law of the State of Delaware, DO HEREBY CERTIFY:

         A. That on February 9, 1995, in lieu of a meeting and pursuant to
Section 141(f) of the General Corporation Law of the State of Delaware, the
Board of Directors of the Corporation did unanimously recommend the adoption of
the following amendment to the Certificate of Incorporation of the Corporation:

         RESOLVED, that the Certificate of Incorporation of the Corporation, as
amended, be amended by deleting Article FOURTH in its entirety and replacing it
so as to read as follows:

         FOURTH: The total number of shares which the Corporation shall have the
authority to issue is 24,500 and the shares shall be divided into classes as

                                   DIVISION A

                                Express Terms of
                            Series A Preferred Stock

         The express terms of SIMCALA, INC.'s (the "Company") series A Preferred
stock (the "Series A Preferred Shares") are as follows:

         1. Number. The total number of Series A Preferred Shares that this
Company shall have authority to issue is one thousand five hundred (1,500),
$1.00 par value per share. All Series A Preferred Shares redeemed, purchased,
surrendered upon exchange or otherwise acquired by the Company shall be
cancelled, retired and eliminated from the Series A Preferred Shares that the
Company shall be authorized to issue. The Company may from time to time take
such appropriate corporate action as may be necessary to reduce the authorized
number of Series A Preferred Shares to reflect any such cancellation, retirement
and elimination of Series A Preferred Shares.

         2. Dividends. No dividends shall be paid on the Series A Preferred
Shares.

         3. Liquidation Preference. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company (a
"Liquidation Event"), the holders of series A Preferred Shares shall be entitled
to receive $2,000 (as adjusted to reflect any share split, combination,
reclassification or similar event affecting the Series A Preferred Shares) (the
"Liquidation Value") for each Series A Preferred Share outstanding. If the
assets of the Company available for distribution to the holders of its capital
stock shall be insufficient to permit payment to the holders of all outstanding
Series A Preferred Shares of the full amount to which they are entitled, then
all of the assets of the Company so available for distribution shall be
distributed ratably among holders of Series A Preferred Shares based upon the
aggregate liquidation preference of the Series A preferred Shares held by each
such holder and the aggregate liquidation preference of all Series A Preferred
Shares. The Liquidation Value shall be paid to holders of Series A Preferred
Shares before any distribution may be made to the holders of common stock or any
other stock of the Company ranking junior to the Series A Preferred Shares as to
distribution of assets upon the occurrence of a Liquidation Event ("Junior
Stock"). After the Liquidation Value shall have been paid to the holders of the
Series A Preferred Shares or funds necessary for such payment shall have been
set aside by the Company in trust for the benefit of the holders of the Series A
Preferred Shares so as to be available for such payment, the holders of Series A
Preferred Shares shall have no further rights with respect to any remaining
assets of the Company legally available for distribution to the holders of its
capital stock. A reorganization, consolidation or merger of the Company or a
sale or other disposition of all or substantially all of the assets of the
Company shall not be treated as a Liquidation Event. The Company shall not make
distributions to the holders of common stock or Junior Stock upon the sale or
other disposition of all or substantially all of the assets of the Company
unless the Company


                                      -2-



   6


shall have paid the Liquidation Value or set aside funds equal to the
Liquidation Value for each of the outstanding Series A Preferred Shares.

         4.  Voting Rights. Except as specifically required by law, the holders
of the Series A Preferred Shares shall not have any right or power to vote on
any question or in any proceeding or to be represented at, or to receive notice
of, any meeting of the Company's shareholders.

         5.  Exchange of Shares.

         (a) The Company, at its option, may at any time from time to time,
exchange outstanding Series A Preferred Shares for Subordinated Promissory
Notes, in the form attached hereto as Exhibit A (the "Exchange Notes"). In the
event that the Company exercises its right to exchange Series A Preferred Shares
into Exchange Notes, each holder of outstanding Series A Preferred shares shall
receive Exchange Notes in an aggregate principal amount equal to the product of
(i) the Liquidation Value times (ii) the number of Series A Preferred Shares
then held by such holder.

         (b) The Company shall mail written notice of its intention to exchange
Exchange Notes for Series A Preferred Shares to each holder of Series A
Preferred Shares not less than 10 days prior to the date on which such exchange
is to be made (the "Exchange Date"). Such notice shall state the Exchange Date
and the place where certificates for such series A Preferred Shares are to be
surrendered in exchange for Exchange Notes.

         (c) From and after the Exchange Date, the Series A Preferred Shares
exchanged for Exchange Notes shall no longer be deemed to be issued and
outstanding, and all rights of the holders of Series A Preferred Shares so
exchanged as stockholders of the Company with respect to such Series A Preferred
Shares (except for the right to receive Exchange Notes) shall cease and
terminate. Upon surrender of the certificates for Series A Preferred Shares so
exchanged (properly endorsed for transfer) in accordance with the Company's
notice, the Company shall cause the Exchange Notes to be duly executed and
delivered as provided above.

         6.  Redemption.

         (a) The Company shall redeem 230 of the issued and outstanding Series A
Preferred Shares on the earlier to occur of the following (the "Initial
Redemption Date"): (i) the date which in six months following the date, as
determined in good faith by the Board of Directors of the Company, that all
three of the Company's furnaces located in Mt. Meigs, Alabama are in operation
or (ii) the second anniversary of the date on which the Series A Preferred
Shares were originally issued. Thereafter, the Company shall redeem Series A
Preferred Shares, as follows:


                                      -3-


   7


                  (i) 100 of the issued and outstanding Series A Preferred
         Shares on each of the first, second and third anniversary of the
         Initial Redemption Date;

                  (ii) 160 of the issued and outstanding Series A Preferred
         shares on each of the fourth and fifth anniversary of the Initial
         Redemption Date; and

                  (iii) 210 of the issued and outstanding Series A Preferred
         Shares on each of the sixth, seventh and eighth anniversary of the
         Initial Redemption Date (the Initial Redemption Date and each other
         date on which Series A Preferred Shares are redeemed under this Section
         6(a) or Section 6(b) shall be referred to as a "Redemption Date").

The redemption price for each series A Preferred Share redeemed shall be the
Liquidation Value at the time of such redemption (the "Redemption Price"). The
number of Series A Preferred Shares required to be redeemed on any Redemption
Date under this Section 6(a) shall be reduced by the number of Series A
Preferred Shares (i) redeemed by the Company under Section 6(b), (ii) exchanged
for Exchange Notes under Section 5, (iii) or otherwise acquired by the Company
at any time prior to such Redemption Date.

         (b) The Company may, at its option at any time from time to time,
redeem any or all of the outstanding Series A Preferred Shares at the Redemption
Price.

         (c) If on any Redemption Date the funds of the Company legally
available for the redemption of Series A Preferred Shares are insufficient to
redeem all Series A Preferred Shares required to be redeemed on such date, the
number of Series A Preferred Shares legally permitted to be redeemed shall be
redeemed, and any Series A Preferred Shares that the Company is legally unable
to redeem shall be redeemed as soon thereafter as funds become legally available
for such redemption.

         (d) At least 10 days prior to a Redemption Date the Company shall mail
written notice of such redemption (the "Redemption Notice") to each holder of
record of the Series A Preferred Shares that are to be redeemed, at its address
shown on the records of the Company; provided, however, that the Company's
failure to give such Redemption Notice with respect to a redemption under
Section 6(a) shall in no way affect its obligation to redeem Series A Preferred
Shares as provided in Section 6(a). The Redemption Notice shall state the
Redemption Date and the Redemption Price, the number of Series A Preferred
Shares to be redeemed, and the place where such holders of Series A Preferred
Shares shall deliver certificates representing the Series A Preferred Shares to
be redeemed.

         (e) Each holder of Series A Preferred Shares to be redeemed shall
surrender the certificate or certificates representing such Series A Preferred
Shares to the Company in proper form for transfer, and thereupon the applicable
Redemption Price for such Series A Preferred Shares shall be paid to such
holder. Each surrendered certificate shall be cancelled and retired and new
certificates representing any Series A Preferred Shares not redeemed shall be
issued to such holder. From and after the date on which the


                                      -4-


   8


Redemption Price for Series A Preferred Shares shall have been paid to the
holders of the Series A Preferred Shares or funds or other property necessary
for such payment shall have been set aside by the Company in trust for the
benefit of the holders of the Series A Preferred Shares so as to be available
for such payment, the Series A Preferred Shares so redeemed shall no longer be
deemed to be outstanding.

         7. Transfer Restrictions. No holder of Series A Preferred Shares may
transfer, assign, sell, pledge, encumber or otherwise dispose of any Series A
Preferred Shares other than as approved in writing by the Board of Directors of
the Company. All certificates representing Series A Preferred Shares shall bear
a legend reflecting these transfer restrictions and all restrictions required by
law.

         8. No Other Rights, Preferences or Privileges. Unless otherwise
required by law, the Series A Preferred Shares shall not have any rights,
preferences or privileges other than those expressly set forth herein.

Company shall be cancelled, retired and eliminated from the Series B Preferred

authorized number of Series B Preferred Shares to reflect any such cancellation,
retirement and elimination of Series B Preferred Shares.

         2. Dividends. The holders of record of Series B Preferred Shares shall
be entitled to receive, when and as declared by the Board of Directors out of
funds legally available therefore, cumulative preferential cash dividends in the

distribution shall be distributed ratably among the holders of the Series B
Preferred Shares based upon the aggregate liquidation preference of the Series B
