Delaware corporation (the "Guarantor"), and The Bank of New York, a New York
banking corporation, as trustee (the "Trustee").

                              W I T N E S S E T H :

          WHEREAS, the Issuers, the Guarantor and the Trustee executed and
delivered an Indenture dated as of July 27, 2001 (the "Indenture"), providing
for the issuance of $385,000,000 principal amount of 10 3/4% Senior Notes due
August 1, 2008 (the "Initial Notes") and Additional Notes (as defined in the
Indenture);

          WHEREAS, pursuant to Section 9.1 of the Indenture, the Issuers, the
Guarantor and the Trustee desire to cure certain ambiguities, technical defects,
inconsistencies and omissions contained in the Indenture, and to make certain
changes to the Indenture that do not materially and adversely affect the rights
of any Noteholder;

          WHEREAS, all acts, conditions and requirements necessary to make this
First Supplemental Indenture a valid and binding agreement in accordance with
its terms and for the purposes herein set forth have been done and taken, and
the execution and delivery of this First Supplemental Indenture has been in all
respects duly authorized;

          NOW THEREFORE, in consideration of the premises, the Issuers, the
Guarantor and the Trustee covenant and agree as follows:

                                   ARTICLE I

                                   AMENDMENTS

          SECTION 1.1. The definition of "Guarantee" in Section 1.1 of the
Indenture is hereby amended to read in its entirety as follows:

               "Guarantee" means any obligation, contingent or otherwise, of any
     Person directly or indirectly guaranteeing any Indebtedness of any Person
     and any obligation, direct or indirect, contingent or otherwise, of such
     Person:

               (i) to purchase or pay (or advance or supply funds for the
     purchase or payment of) such Indebtedness or other obligation of such
     Person (whether arising by virtue of partnership arrangements, or by
     agreements to keep-well, to purchase assets, goods, securities or services,
     to take-or-pay or to maintain financial statement conditions or otherwise)
     but shall not include take-or-pay arrangements or other agreements to
     purchase goods or services that are not entered into for the purpose of
     purchasing or paying such Indebtedness of such Person; or

                                       2
<PAGE>

               (ii) entered into for the purpose of assuring in any other manner
     the obligee of such Indebtedness of the payment thereof or to protect such
     obligee against loss in respect thereof (in whole or in part);

     provided, however, that the term "Guarantee" shall not include endorsements
     for collection or deposit in the ordinary course of business. The term
     "Guarantee" used as a verb has a corresponding meaning. The term
     "Guarantor" shall mean any Person Guaranteeing any obligation.

          SECTION 1.2. The following definition of "Financing Entity" is hereby
added to Section 1.1 of the Indenture:

          "Financing Entity" means any Wholly Owned Subsidiary formed solely for
     the purpose of effecting a receivables or inventory financing program so

     recourse to, any other Restricted Subsidiary.

          SECTION 1.3. Subclause (ix) of the definition of "Permitted Liens" is
hereby amended to read in its entirety as follows:

               (ix) Liens on the inventory or accounts receivable of the Company
     or any Restricted Subsidiary securing Indebtedness permitted under the
     provisions described in clause (b)(i) under Section 4.12;

          SECTION 1.4. Section 4.12(b)(i) of the Indenture is amended to read in
its entirety as follows:

               (i) Indebtedness Incurred by the Company, any Financing Entity
     and any Foreign Restricted Subsidiary pursuant to any Credit Facilities,
     provided, however, that, immediately after giving effect to any such
     Incurrence, the aggregate principal amount of all Indebtedness Incurred
     under this clause (i) and then outstanding does not exceed the greater of
     (A) $750 million less the sum of all principal payments with respect to
     such Indebtedness pursuant to Section 4.15(b)(iii)(1) and (B) the sum of
     (x) 60% of the book value of the inventory of the Company and its
     Restricted Subsidiaries and (y) 85% of the book value of the accounts
     receivable of the Company and its Restricted Subsidiaries, provided
     further, however, that in no event shall the aggregate principal amount of
     all Indebtedness Incurred under this clause (i) at any time outstanding
     exceed $1.2 billion;

          SECTION 1.5. The reference in the third sentence of Section 9.6 of the
Indenture to Section 10.4 is amended to refer to Section 11.4.

                                   ARTICLE II

                            MISCELLANEOUS PROVISIONS

          SECTION 2.1. For all purposes of this First Supplemental Indenture,
except as

                                       3
<PAGE>

otherwise defined or unless the context otherwise requires, capitalized terms
used in this First Supplemental Indenture and defined in the Indenture have the
meaning specified in the Indenture.

          SECTION 2.2. Except as specifically amended and supplemented by this
First Supplemental Indenture, the Indenture shall remain in full force and
effect and is hereby ratified and confirmed.

          SECTION 2.3. The laws of the State of New York shall govern this First
Supplemental Indenture without regard to principles of conflict of laws.

          SECTION 2.4. All agreements of the Issuers and the Guarantor in this
First Supplemental Indenture shall bind their successors. All agreements of the
Trustee in this First Supplemental Indenture shall bind its successors.

          SECTION 2.5. The parties may sign any number of counterparts of this
First Supplemental Indenture. Each such counterpart shall be an original, but
all of them together represent the same agreement.

                         SERIES A JUNIOR PREFERRED STOCK

                                       OF

                         UNITED STATES STEEL CORPORATION

                             -----------------------

                     Pursuant to Section 151 of the General
                    Corporation Law of the State of Delaware

                            ------------------------

          The undersigned DOES HEREBY CERTIFY that the following resolution was
duly adopted by the Board of Directors of United States Steel Corporation, a
Delaware corporation (formerly a Delaware limited liability company) (the
"Company") creating a series of 2,000,000 shares of Preferred Stock designated
as Series A Junior Preferred Stock:

          RESOLVED, that pursuant to the authority vested in the Board of
     Directors of this Company in accordance with the provisions of its
     Certificate of Incorporation, as amended, a series of Preferred Stock of
     the Corporation be, and it hereby is, created, and that the designation and
     amount thereof and the voting powers, preferences and relative,
     participating, optional and other special rights of the shares of such
     series, and the qualifications, limitations or restrictions thereof are as
     follows:

     Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Preferred Stock" and the number of shares
constituting such series shall be 2,000,000.

     Section 2. Dividends and Distributions.

          (a) Subject to the prior and superior rights of the holders of any
          shares of any series of Preferred Stock ranking prior and superior to
          the shares of Series A Junior Preferred Stock with respect to
          dividends, the holders of shares of Series A Junior Preferred Stock
          shall be entitled to receive, when, as and if declared by the Board of
          Directors out of funds legally available for the purpose, quarterly
          dividends payable in cash on the first day of March, June, September
          and December in each year (each such date being referred to herein as
          a "Quarterly Dividend Payment Date"), commencing on the first
          Quarterly Dividend Payment Date after the first issuance of a share or
          fraction of a share of Series A Junior Preferred Stock, in an amount
          per share (rounded to the nearest cent) equal to the greater of (a)
          $5.00 or (b) subject to the provision for adjustment hereinafter set
          forth, 100 times the aggregate per share amount of all cash dividends,
          and 100 times the aggregate per share amount (payable in kind) of all
          non-cash dividends or other distributions other than a dividend
          payable in shares of Common Stock or a subdivision of the outstanding
          shares of Common Stock (by reclassification or otherwise), to be or
          being declared on the Common Stock, par value $1.00 per share, of the
          Corporation (the "Common Stock") with respect to the same dividend
          period. If the Quarterly Dividend Payment Date is a Saturday, Sunday
          or legal holiday then such Quarterly Dividend Payment Date shall be
          the first immediately preceding calendar day which is not a Saturday,
          Sunday or legal holiday. In the event the Corporation shall at any
          time after December 31, 2001 (the "Rights Declaration Date") (i)
          declare any dividend on Common
<PAGE>

          Stock payable in shares of Common Stock, (ii) subdivide the
          outstanding Common Stock, or (iii) combine the outstanding Common
          Stock into a smaller number of shares, then in each such case the
          amount to which holders of shares of Series A Junior Preferred Stock
          were entitled immediately prior to such event under clause (b) of the
          preceding sentence shall be adjusted by multiplying such amount by a
          fraction the numerator of which is the number of shares of Common
          Stock outstanding immediately after such event and the denominator of
          which is the number of shares of Common Stock that were outstanding
          immediately prior to such event.

          (b) The Corporation shall declare a dividend or distribution on the
          Series A Junior Preferred Stock as provided in paragraph (A) above
          immediately prior to the time it declares a dividend or distribution
          on the Common Stock (other than a dividend payable in shares of Common
          Stock); provided that, in the event no dividend or distribution shall
          be declared on the Common Stock with respect to a particular dividend
          period, a dividend of $5.00 per share on the Series A Junior Preferred
          Stock shall nevertheless be payable on such Quarterly Dividend Payment
          Date with respect to such quarterly period.

          (c) Dividends shall begin to accrue and be cumulative on outstanding
          shares of Series A Junior Preferred Stock from the Quarterly Dividend
          Payment Date next preceding the date of issue of such shares of Series
          A Junior Preferred Stock, unless the date of issue of such shares is
          prior to the record date for the first Quarterly Dividend Payment
          Date, in which case dividends on such shares shall begin to accrue
          from the date of issue of such shares, or unless the date of issue is
          a Quarterly Dividend Payment Date or is a date after the record date
          for the determination of holders of shares of Series A Junior
          Preferred Stock entitled to receive a quarterly dividend and before
          such Quarterly Dividend Payment Date, in either of which events such
          dividends shall begin to accrue and be cumulative from such Quarterly
          Dividend Payment Date. Accrued but unpaid dividends shall not bear
          interest. Dividends paid on the shares of Series A Junior Preferred
          Stock in an amount less than the total amount of such dividends at the
          time accrued and payable on such shares shall be allocated pro rata on
          a share-by-share basis among all such shares at the time outstanding.
          The Board of Directors may fix a record date for the determination of
          holders of shares of Series A Junior Preferred Stock entitled to
          receive payment of a dividend or distribution declared thereon, which
          record date shall be no more than 30 days prior to the date fixed for
          the payment thereof. Dividends in arrears may be declared and paid at
          any time, without reference to any Quarterly Dividend Payment Date, to
          holders of record on such date, not exceeding 45 days preceding the
          payment date thereof, as may be fixed by the Board of Directors.

          (d) Except as hereinafter provided, no dividends shall be declared or
          paid or set apart for payment on the shares of Series A Junior
          Preferred Stock for any period if the Corporation shall be in default
          in the payment of any dividends (including cumulative dividends, if
          applicable) on any shares of Preferred Stock ranking, as to dividends,
          prior to the Series A Junior Preferred Stock, unless the same shall be
          contemporaneously declared and paid.

          (e) Dividends payable on the Series A Junior Preferred Stock for the
          initial dividend period and for any period less than a full quarterly
          period, shall be computed on the basis of a 360-day year of 30-day
          months.

     Section 3. Voting Rights. The holders of shares of Series A Junior
Preferred Stock shall have the following voting rights:

          (a) Each share of Series A Junior Preferred Stock shall entitle the
          holder thereof to one vote on all matters submitted to a vote of the
          stockholders of the Corporation. The holders of Series A Junior
          Preferred Stock shall be entitled to notice of all meetings of the
          stockholders of the Corporation.

                                       2
<PAGE>

          (b) Except as otherwise provided herein or by law, the holders of
          shares of Series A Junior Preferred Stock and the holders of shares of
          Common Stock shall vote together as one class on all matters submitted
          to a vote of stockholders of the Corporation.

          (c) If, on the date used to determine stockholders of record for any
          meeting of stockholders for the election of directors, a default in
          preference dividends on the Preferred Stock shall exist, the number of
          directors constituting the Board of Directors of the Corporation shall
          be increased by two, and the holders of the Preferred Stock of all
          series (whether or not the holders of such series of Preferred Stock
          would be entitled to vote for the election of directors if such
          default in preference dividends did not exist), shall have the right
          at such meeting, voting together as a single class without regard to
          series, to the exclusion of the holders of Common Stock, to elect two
          directors of the Corporation to fill such newly created directorships.
          Each director elected by the holders of shares of Preferred Stock
          (herein called a "Preferred Director"), shall continue to serve as
          such director for the full term for which he shall have been elected,
          notwithstanding that prior to the end of such term a default in
          preference dividends shall cease to exist. Any Preferred Director may
          be removed by, and shall not be removed except by, the vote of the
          holders of record of the outstanding shares of Preferred Stock, voting
          together as a single class without regard to series, at a meeting of
          the stockholders, or of the holders of shares of Preferred Stock,
          called for the purpose. So long as a default in any preference
          dividends on the Preferred Stock shall exist (i) any vacancy in the
          office of a Preferred Director may be filled (except as provided in
          the following clause (ii)) by an instrument in writing signed by the
          remaining Preferred Director and filed with the Corporation and (ii)
          in the case of the removal of any Preferred Director, the vacancy may
          be filled by the vote of the holders of the outstanding shares of
          Preferred Stock, voting together as a single class without regard to
          series, at the same meeting at which such removal shall be voted. Each
          director appointed as aforesaid by the remaining Preferred Director
          shall be deemed, for all purposes hereof, to be a Preferred Director.
          Whenever the term of office of the Preferred Directors shall end and
          no default in preference dividends shall exist, the number of
          directors constituting the Board of Directors of the Corporation shall
          be reduced by two. For the purposes of this paragraph (C), a "default
          in preference dividends" on the Preferred Stock shall be deemed to
          have occurred whenever the amount of accrued and unpaid dividends upon
          any series of the Preferred Stock shall be equivalent to six full
          quarterly dividends or more, and, having so occurred, such default
          shall be deemed to exist thereafter until, but only until, all accrued
          dividends on all shares of Preferred Stock of each and every series
          then outstanding shall have been paid through the last Quarterly
          Dividend Payment Date.

     Section 4. Certain Restrictions.

          (a)Whenever quarterly dividends or other dividends or distributions
          payable on the Series A Junior Preferred Stock as provided in Section
          2 are in arrears, thereafter and until all accrued and unpaid
          dividends and distributions, whether or not declared, on shares of
          Series A Junior Preferred Stock outstanding shall have been paid in
          full, the Corporation shall not:

               (i) declare or pay dividends on, make any other distributions on
               (other than a dividend in Common Stock or in any other stock of
               the Corporation ranking junior to the Series A Junior Preferred
               Stock as to dividends and upon liquidation, dissolution or
               winding up and other than as provided in subparagraph (ii) of
               this section), or redeem or purchase or otherwise acquire for
               consideration (except by conversion into or exchange for stock of
               the Corporation ranking junior to the Series A Junior Preferred
               Stock as to dividends and upon dissolution, liquidation or
               winding up), any shares of stock

                                       3
<PAGE>

               ranking junior (either as to dividends or upon liquidation,
               dissolution or winding up) to the Series A Junior Preferred
               Stock;

               (ii) declare or pay dividends on or make any other distributions
               on any shares of stock ranking on a parity (either as to
               dividends or upon liquidation, dissolution or winding up) with
               the Series A Junior Preferred Stock, except dividends paid
               ratably on the Series A Junior Preferred Stock and all stock
               ranking on a parity with the Series A Junior Preferred Stock as
               to dividends on which dividends are payable or in arrears in
               proportion to the total amounts to which the holders of all such
               shares are then entitled;

               (iii) redeem or purchase or otherwise acquire for consideration
               shares of any stock ranking on a parity (either as to dividends
               or upon liquidation, dissolution or winding up) with the Series A
               Junior Preferred Stock, provided that the Corporation may at any
               time redeem, purchase or otherwise acquire shares of any such
               parity stock in exchange for shares of any stock of the
               Corporation ranking junior (as to dividends and upon dissolution,
               liquidation or winding up) to the Series A Junior Preferred
               Stock;

               (iv) purchase or otherwise acquire for consideration any shares
               of Series A Junior Preferred Stock, except in accordance with a
               purchase offer made in writing or by publication (as determined
               by the Board of Directors) to all holders of such shares upon
               such terms as the Board of Directors, after consideration of the
               respective annual dividend rates and other relative rights and
               preferences of the respective series and classes, shall determine
               in good faith will result in fair and equitable treatment among
               the respective series or classes.

          (b) The Corporation shall not permit any subsidiary of the Corporation
          to purchase or otherwise acquire for consideration any shares of stock
          of the Corporation unless the Corporation could, under paragraph (A)
          of this Section 4, purchase or otherwise acquire such shares at such
          time and in such manner.

     Section 5. Reacquired Shares. Any shares of Series A Junior Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
to be created by resolution or resolutions of the Board of Directors, subject to
the conditions and restrictions on issuance set forth herein.

     Section 6. Liquidation, Dissolution or Winding Up.

          (a) In the event of any voluntary or involuntary liquidation,
          dissolution or winding up of the Corporation, the holders of the
          Series A Junior Preferred Stock shall be entitled to receive the
          greater of (a) $100 per share, plus accrued dividends to the date of
          distribution, whether or not earned or declared, or (b) an amount per
          share, subject to the provision for adjustment hereinafter set forth,
          equal to 100 times the aggregate amount to be distributed per share to
          holders of Common Stock (the "Series A Liquidation Preference"). In
          the event the Corporation shall at any time after the Rights
          Declaration Date (i) declare any dividend on Common Stock payable in
          shares of Common Stock, (ii) subdivide the outstanding Common Stock or
          (iii) combine the outstanding Common Stock into a smaller number of
          shares, then in each such case the amount to which holders of shares
          of Series A Junior Preferred Stock were entitled immediately prior to
          such event pursuant to clause (b) of the preceding sentence shall be
          adjusted by multiplying such amount by a fraction the numerator of
          which is the number of shares of Common Stock outstanding immediately
          after such event and the denominator of which

                                       4
<PAGE>

          is the number of shares of Common Stock that were outstanding
          immediately prior to such event.

          (b) In the event, however, that there are not sufficient assets
          available to permit payment in full of the Series A Liquidation
          Preference and the liquidation preferences of all other series of
          preferred stock, if any, which rank on a parity with the Series A
          Junior Preferred Stock, then such remaining assets shall be
          distributed ratably to the holders of such parity shares in proportion
          to their respective liquidation preferences.

     Section 7. Consolidation, Merger, etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Junior Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of shares
of Series A Junior Preferred Stock shall be adjusted by multiplying such amount
by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     Section 8. Optional Redemption.

          (a) The Corporation shall have the option to redeem the whole or any
          part of the Series A Junior Preferred Stock at any time on at least 30
          days notice in accordance with the provisions of paragraph (B) of this
          Section 8 at a redemption price equal to, subject to the provision for
          adjustment hereinafter set forth, 100 times the "current per share
          market price" of the Common Stock on the date of the mailing of the
          notice of redemption, together with unpaid accumulated dividends to
          the date of such redemption. In the event the Corporation shall at any
          time after December 31, 2001 (i) declare any dividend on Common Stock
          payable in shares of Common Stock, (ii) subdivide the outstanding
          Common Stock or (iii) combine the outstanding Common Stock into a
          smaller number of shares, then in each such case the amount to which
          holders of shares of Series A Junior Preferred Stock were otherwise
          entitled immediately prior to such event under the preceding sentence
          shall be adjusted by multiplying such amount by a fraction the
          numerator of which is the number of shares of Common Stock outstanding
          immediately after such event and the denominator of which is the
          number of shares of Common Stock that were outstanding immediately
          prior to such event. The "current per share market price" on any date
          shall be deemed to be the average of the closing price per share of
          such Common Stock for the 10 consecutive Trading Days (as such term is
          hereinafter defined) immediately prior to such date. The closing price
          for each day shall be the last sale price, regular way, or, in case no
          such sale takes place on such day, the average of the closing bid and
          asked prices regular way, in either case as reported in the principal
          consolidated transaction reporting system with respect to securities
          listed or admitted to trading on the New York Stock Exchange or, if
          the Common Stock is not listed or admitted to trading on the New York
          Stock Exchange, as reported in the principal consolidated transaction
          reporting system with respect to securities listed or admitted to
          trading on the principal national securities exchange on which the
          Common Stock is listed or admitted to trading or, if the Common Stock
          is not listed or admitted to trading on any national securities
          exchange, the last quoted price or, if not so quoted the average of
          the high bid and low asked prices in the over-the-counter market, as
          reported by the National Association of Securities Dealers, Inc.
          Automated Quotations System ("NASDAQ") or such other system then in
          use or, if on any such date the Common Stock

                                       5
<PAGE>

          is not quoted by any such organization, the average of the closing bid
          and asked prices as furnished by a professional market maker making a
          market in the Common Stock selected by the Corporation. If on such
          date no such market maker is making a market in the Common Stock, the
          fair value of the Common Stock on such date as determined in good
          faith by the Board of Directors of the Corporation shall be used. The
          term "Trading Day" shall mean a day on which the principal national
          securities exchange on which the Common Stock is listed or admitted to
          trading is open for the transaction of business or, if the Common
          Stock is not listed or admitted to trading on any national securities
          exchange, a Monday, Tuesday, Wednesday, Thursday or Friday on which
          banking institutions in the State of New York are not authorized or
          obligated by law or executive order to close.

          (b) Whenever shares of Series A Junior Preferred Stock are to be
          redeemed, the Corporation shall mail a notice ("Notice of Redemption")
          by first-class mail, postage prepaid, to each holder of record of
          shares of Series A Junior Preferred Stock to be redeemed and to the
          transfer agent for the Series A Junior Preferred Stock. The Notice of
          Redemption shall be addressed to the holder at the address of the
          holder appearing on the stock transfer books of the Corporation
          maintained by the transfer agent for the Series A Junior Preferred
          Stock. The Notice of Redemption shall include a statement of (i) the
          redemption date, (ii) the redemption price, (iii) the number of shares
          of Series A Junior Preferred Stock to be redeemed, (iv) the place or
          places where shares of the Series A Junior Preferred Stock are to be
          surrendered for payment of the redemption price, (v) that the
          dividends on the shares to be redeemed will cease to accrue on such
          redemption date, and (vi) the provision under which redemption is
          made. No defect in the Notice of Redemption or in the mailing thereof
          shall affect the validity of the redemption proceedings, except as
          required by law. From the date on which a Notice of Redemption shall
          have been given as aforesaid and the Corporation shall have deposited
          with the transfer agent for the Series A Junior Preferred Stock a sum
          sufficient to redeem the shares of Series A Junior Preferred Stock as
          to which Notice of Redemption has been given, with irrevocable
          instructions and authority to pay the redemption price to the holders
          thereof, or if no such deposit is made, then upon such date fixed for
          redemption (unless the Corporation shall default in making payment of
          the redemption price), all rights of the holders thereof as
          stockholders of the Corporation by reason of the ownership of such
          shares (except their right to receive the redemption price thereof,
          but without interest), shall terminate including, but not limited to,
          their right to receive dividends, and such shares shall no longer be
          deemed outstanding. The Corporation shall be entitled to receive, from
          time to time, from the transfer agent for Series A Junior Preferred
          Stock the interest, if any, on such monies deposited with it and the
          holders of any shares so redeemed shall have no claim to any such
          interest. In case the holder of any shares so called for redemption
          shall not claim the redemption price for his shares within one year
          after the date of redemption, the transfer agent for the Series A
          Junior Preferred Stock shall, upon demand, pay over to the Corporation
          such amount remaining on deposit and the transfer agent for the Series
          A Junior Preferred Stock shall thereupon be relieved of all
          responsibility to the holders of such shares and such holder of the
          shares of the Series A Junior Preferred Stock so called for redemption
          shall look only to the Corporation for the payment thereof.

          (c) In the event that fewer than all the outstanding shares of the
          Series A Junior Preferred Stock are to be redeemed, the number of
          shares to be redeemed shall be determined by the Board of Directors
          and the shares to be redeemed shall be determined by lot or pro rata
          as may be determined by the Board of Directors or by any other method
          as may be determined by the Board of Directors in its sole discretion
          to be equitable.

          (d) If the Corporation shall be in default in the payment of any
          dividends (including cumulative dividends, if applicable) on any
          shares of Preferred Stock ranking, as to dividends, prior to the
          Series A Junior Preferred Stock, then no shares of the Series A

                                       6
<PAGE>

          Junior Preferred Stock shall be redeemed and the Corporation shall not
          purchase or otherwise acquire any shares of the Series A Junior
          Preferred Stock.

     Section 9. Ranking.

          (a) The Series A Junior Preferred Stock shall rank junior to all other
          series of the Corporation's Preferred Stock as to the payment of
          dividends and the distribution of assets upon liquidation, dissolution
          or winding up, unless the terms of any such series shall provide
          otherwise.

          (b) For purposes of this resolution, any stock of any class or classes
          of the Corporation shall be deemed to rank:

               (i) prior to the shares of the Series A Junior Preferred Stock,
               either as to dividends or upon liquidation, dissolution or
               winding up, if the holders of such class or classes shall be
               entitled to the receipt of dividends or of amounts distributable
               upon dissolution, liquidation or winding up of the Corporation,
               whether voluntary or involuntary, as the case may be, in
               preference or priority to the holders of shares of the Series A
               Junior Preferred Stock. Each holder of any share of the Series A
               Junior Preferred Stock, by his acceptance thereof, expressly
               covenants and agrees that the rights of the holders of any shares
               of any other series of Preferred Stock of the Corporation to
               receive dividends or amounts distributable upon dissolution,
               liquidation or winding up of the Corporation, whether voluntary
               or involuntary, shall be and hereby are expressly prior to his
               rights unless in the case of any particular series of Preferred
               Stock the certificate or other instrument creating or evidencing
               the same expressly provides that the rights of the holders of
               such series shall not be prior to the shares of the Series A
               Junior Preferred Stock; and

               (ii) on a parity with shares of the Series A Junior Preferred
               Stock, either as to dividends or upon liquidation, whether or not
               the dividend rates, dividend payment dates or redemption or
               liquidation prices per share or sinking fund provisions, if any,
               be different from those of the Series A Junior Preferred Stock,
               if the holders of such stock shall be entitled to the receipt of
               dividends or of amounts distributable upon dissolution,
               liquidation or winding up of the Corporation, whether voluntary
               or involuntary, as the case may be, in proportion to their
               respective dividend rates or liquidation prices, without
               preference or priority, one over the other, as between the
               holders of such stock and the holders of shares of the Series A
               Junior Preferred Stock; and

               (iii) junior to shares of the Series A Junior Preferred Stock,
               either as to dividends or upon liquidation, if such class or
               classes shall be Common Stock or if the holders of shares of the
               Series A Junior Preferred Stock shall be entitled to receipt of
               dividends or of amounts distributable upon dissolution,
               liquidation or winding up of the Corporation, whether voluntary
               or involuntary, as the case may be, in preference or priority to
               the holders of shares of such class or classes.

     Section 10. Amendment. Except as otherwise set forth in this Certificate of
Designation, Preferences and Rights with respect to the Series A Junior
Preferred Stock, holders of Series A Junior Preferred Stock shall not have any
special powers and their consent shall not be required for taking any corporate
action, provided, however, that:

          (1) Unless the vote or consent of the holders of a greater number of
          shares shall then be required by law, the consent of the holders of at
          least 66% of all of the shares of the Series A Junior Preferred Stock
          at the time outstanding, given in person or by proxy, either in
          writing or by a vote at a meeting called for the purpose at which the
          holders of

                                       7
<PAGE>

          shares of the Series A Junior Preferred Stock shall vote together as a
          separate class, shall be necessary for authorizing, effecting or
          validating the amendment, alteration or repeal of any of the
          provisions of the Certificate of Incorporation or of any certificate
          amendatory thereof or supplemental thereto (including any Certificate
          of Designation, Preferences and Rights or any similar document
          relating to any series of Preferred Stock) so as to affect adversely
          the powers, preferences, or rights, of this Series A Junior Preferred
          Stock. The increase of the authorized amount of the Preferred Stock,
          or the creation, authorization or issuance of any shares of any other
          class of stock of the Corporation ranking prior to or on a parity with
          the shares of the Series A Junior Preferred Stock as to dividends or
          upon liquidation, or the reclassification of any authorized or
          outstanding stock of the Corporation into any such prior or parity
          shares, or the creation, authorization or issuance of any obligation
          or security convertible into or evidencing the right to purchase any
          such prior or parity shares shall not be deemed to affect adversely
          the powers, preferences or rights of the Series A Junior Preferred
          Stock.

     Section 11. Fractional Shares. Series A Junior Preferred Stock may be
issued in fractions of a share which shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Junior Preferred Stock.

     FURTHER RESOLVED, that this Certificate of Designations shall be effective
as of 11:59 p.m. on December 31, 2001.

                                       8

     IN WITNESS WHEREOF, the Company has caused this Certificate of Designations
