                                                   Name: Bernard J. Ebbers
                                                   Title: President



                                              EXHIBIT A

            (A) Common Stock. There shall be two series of common stock created,
having the number of shares and the voting powers, preferences, designations,
rights, qualifications, limitations or restrictions set forth below:

            (i) WorldCom Stock. One series of common stock of the Corporation is
      hereby created and designated as "WorldCom, Inc.--WorldCom Group Common
      Stock" ("WorldCom Stock") consisting of 4.85 billion shares.

            (ii) MCI Stock. One series of common stock of the Corporation is
      hereby created and designated as "WorldCom, Inc.--MCI Group Common Stock"
      ("MCI Stock") consisting of 150 million shares.

            (iii) Upon the date on which this Section A of Article 4 shall
      become effective, and without any further action on the part of the
      Corporation or its stockholders, each share of the Corporation's common
      stock, par value $0.01 per share, that is issued and outstanding shall be
      changed into one share of WorldCom Stock and 1/25 (0.04) of a share of MCI
      Stock.

            (iv) For the purpose of making "lawful and adequate provision" to
      implement the existing right of the holders of the Company's Series B
      Convertible Preferred Stock to acquire and receive upon the conversion of
      the Series B Convertible Preferred Stock such shares of stock issuable
      with respect to or in exchange for each outstanding share of the Company's
      "Common Stock" (as such term is defined in Exhibit B to these Second
      Amended and Restated Articles of Incorporation) as would have been
      received upon conversion of the Series B Convertible Preferred Stock at
      the "Conversion Rate" (as such term is defined in Section 5(a) of said
      Exhibit B) then in effect, all references to a share of "Common Stock" of
      the Company in Section 5 and Section 7 of Exhibit B shall be deemed, from
      and after the date on which this Section A of Article 4 shall become
      effective, to refer to one share of WorldCom Stock and 0.04 of a share of
      MCI Stock (or such other number and designation of shares as may then be
      applicable following lawful adjustment pursuant to Section 6 of Exhibit
      B).

            Section 1. Distributions and Share Dividends. Subject to the prior
and superior or other rights of the holders of the preferred stock or any other
shares of the Corporation and subject to the limitations provided for below in
this Section 1, distributions and share dividends may be declared and paid upon
either series of common stock, as the board of directors may determine and with
the effect provided for in these Second Amended and Restated Articles of
Incorporation.

            (A) Distributions on WorldCom Stock. Distributions on WorldCom Stock
may be declared and paid only out of the lesser of:

            (i) the funds legally available for that purpose; and

            (ii) the WorldCom Group Available Distribution Amount.


                                        2


            (B) Distributions on MCI Stock. Distributions on MCI Stock may be
declared and paid only out of the lesser of:

            (i) the funds legally available for that purpose; and

            (ii) the MCI Group Available Distribution Amount.

            (C) Additional Limitations on Distributions and Share Dividends. The
board of directors may declare and pay share dividends of WorldCom Stock and MCI
Stock (or distributions of Convertible Securities convertible into or
exchangeable or exercisable for shares of WorldCom Stock or MCI Stock) or
distributions of assets (including securities) or properties attributed to the
WorldCom Group or the MCI Group on shares of common stock only as follows or as
permitted by Section 4:

            (i) on shares of WorldCom Stock-share dividends of WorldCom Stock
      (or distributions of Convertible Securities convertible into or
      exchangeable or exercisable for shares of WorldCom Stock) or distributions
      of assets (including securities) or properties attributed to the WorldCom
      Group;

            (ii) on shares of MCI Stock-share dividends of MCI Stock (or
      distributions of Convertible Securities convertible into or exchangeable
      or exercisable for shares of MCI Stock) or distributions of assets
      (including securities) or properties attributed to the MCI Group.

            (iii) on shares of MCI Stock-share dividends of WorldCom Stock (or
      distributions of Convertible Securities convertible into or exchangeable
      or exercisable for shares of WorldCom Stock), but only if (x) the MCI
      Group is a Holder Group holding an Inter-Group Interest in the WorldCom
      Group and (y) the sum of:

                  (1) the number of shares of WorldCom Stock to be so issued (or
            the number of such shares that would be issuable upon conversion,
            exchange or exercise of any Convertible Securities to be so issued);
            and

                  (2) the number of shares of WorldCom Stock that are issuable
            upon conversion, exchange or exercise of any Convertible Securities
            then outstanding that are attributed as a liability to, or an equity
            interest in, the MCI Group

      is less than or equal to the Number of Shares Issuable with Respect to the
      Inter-Group Interest in the WorldCom Group held by the MCI Group;

            (iv) on shares of WorldCom Stock-share dividends of MCI Stock (or
      distributions of Convertible Securities convertible into or exchangeable
      or exercisable for shares of MCI Stock), but only if (x) the WorldCom
      Group is a Holder Group holding an Inter-Group Interest in the MCI Group
      and (y) the sum of:

                  (1) the number of shares of MCI Stock to be so issued (or the
            number of such shares that would be issuable upon conversion,
            exchange or exercise of any Convertible Securities to be so issued);
            and


                                        3


               (2) the number of shares of MCI Stock that are issuable upon
          conversion, exchange or exercise of any Convertible Securities then
          outstanding that are attributed as a liability to, or an equity
          interest in, the WorldCom Group

      is less than or equal to the Number of Shares issuable with Respect to the
      Inter-Group Interest in the MCI Group held by the WorldCom Group;

            (v) on shares of MCI Stock-distributions of assets (including
      securities) or properties attributed as an asset to the WorldCom Group,
      but only if the number or amount of such assets (including securities) or
      properties to be so paid is less than or equal to the product of:

                  (1) the number or amount of such assets (including securities)
            or properties to be paid concurrently to holders of outstanding
            WorldCom Stock; and

                  (2) a fraction (which may be greater than one), the numerator
            of which is equal to the Number of Shares Issuable with Respect to
            the Inter-Group Interest in the WorldCom Group held by the MCI Group
            and the denominator of which is equal to the number of outstanding
            shares of WorldCom Stock, in each case, on the record date for such
            distribution; and

            (vi) on shares of WorldCom Stock-distributions of assets (including
      securities) or properties attributed as an asset to the MCI Group, but
      only if the number or amount of such assets (including securities) or
      properties to be so paid is less than or equal to the product of:

                  (1) the number or amount of such assets (including securities)
            or properties to be paid concurrently to holders of outstanding MCI
            Stock; and

                  (2) a fraction (which may be greater than one), the numerator
            of which is equal to the Number of Shares Issuable with Respect to
            the Inter-Group Interest in the MCI Group held by the WorldCom Group
            and the denominator of which is equal to the number of outstanding
            shares of MCI Stock, in each case, on the record date for such
            distribution.

            For purposes of this Section l(C), any outstanding Convertible
Securities that are convertible into or exchangeable or exercisable for any
other Convertible Securities which are themselves convertible into or
exchangeable or exercisable for any series of common stock (or other Convertible
Securities that are so convertible, exchangeable or exercisable) shall be deemed
to have been converted, exchanged or exercised in full for such Convertible
Securities.

            (D) Discrimination Between Series of Common Stock. The board of
directors, subject to the provisions of this Section 1, may at any time declare
and pay distributions and share dividends exclusively on WorldCom Stock or
exclusively on MCI Stock, in equal or unequal amounts, notwithstanding the
relationship between the Available Distribution Amount with respect to either
Group, the amount of distributions and share dividends previously declared or
paid on either series, the respective voting or liquidation rights of either
series or other factor.


                                      4


            Section 2. Voting Rights.

            (A) General. Except as otherwise provided by law, by the terms of
any outstanding preferred stock or by any provision in these Second Amended and
Restated Articles of Incorporation allocating the power to vote on a specified
matter to other shareholders or in a different manner, the common stock shall
together have unlimited voting rights. Both series of common stock shall vote on
all matters together as a single voting group, except as otherwise provided by
law or by any provision in these Second Amended and Restated Articles of
Incorporation.

            (B) Number of Votes for Each Series of Common Stock. On each matter
to be voted on by the holders of each series of common stock voting together as
a single voting group, the number of votes per share of each series shall be as
follows:

            (i) each outstanding share of WorldCom Stock shall have one vote;
      and

            (ii) each outstanding share of MCI Stock shall have a number of
      votes (including a fraction of one vote) equal to the quotient, rounded to
      the nearest 1/10,000 (.0001), of (1) the average Market Value of one share
      of MCI Stock during the 20-Trading Day period ending on the tenth Trading
      Day prior to the record date for determining the shareholders entitled to
      vote, divided by (2) the average Market Value of one share of WorldCom
      Stock during such 20-Trading Day period.

Notwithstanding the foregoing provisions of this Section 2(B), if shares of only
one series of common stock are outstanding on the record date for determining
the holders of common stock entitled to vote on any matter, then each share of
that series shall be entitled to one vote and, if either series of common stock
is entitled to vote as a separate voting group with respect to any matter, each
share of that series shall, for the purpose of such vote, be entitled to one
vote on such matter.

            Section 3. Liquidation Rights.

            (A) General. In the event of any voluntary or involuntary
dissolution of the Corporation, after payment or provision for payment of the
debts and other liabilities of the Corporation and after making provision for
any outstanding preferred stock and any other shares prior and superior to
common stock as to payments upon dissolution (regardless of the Group to which
such shares are attributed), the holders of WorldCom Stock and MCI Stock shall
be entitled to receive the net assets of the Corporation remaining for
distribution to holders of the common stock (regardless of the Group to which
such assets are then attributed) in an amount determined on a per share basis in
proportion to the liquidation units per share of such series.

            For purposes of this Section 3, neither (x) the voluntary sale,
lease, exchange or other disposition of all or substantially all of the property
or assets of the Corporation; (y) a merger of the Corporation or a share
exchange by the Corporation with one or more other corporations (whether or not
the Corporation is the corporation surviving such merger or the acquiring
company in such share exchange); nor (z) any transaction or event pursuant to
Section 4 shall be deemed a voluntary or involuntary dissolution of the
Corporation.


                                        5


            (B) Liquidation Units for Each Series of Common Stock. The
liquidation units per share of each series of common stock shall be as follows:

            (i) each share of WorldCom Stock shall have one liquidation unit;
      and

            (ii) each share of MCI Stock shall have 1/25 of one liquidation
      unit.

provided that, if the Corporation shall in any manner subdivide (by stock split,
reclassification or otherwise) or combine (by reverse stock split,
reclassification or otherwise) the outstanding shares of either series of common
stock, or declare and pay a share dividend of either series of common stock to
holders of such series, the per share liquidation units of the series of common
stock, as adjusted from time to time, shall be appropriately adjusted, as
determined by the board of directors, so as to avoid any dilution in the
aggregate, relative liquidation rights of the shares of either series of common
stock.

            Section 4. Special Distributions on, and Conversion or Redemption
of, WorldCom Stock and MCI Stock.

            (A) Special Distributions on, and Conversion or Redemption of,
WorldCom Stock if a Disposition of All or Substantially All Assets of the
WorldCom Group Occurs.

            (i) In the event of the Disposition, in one transaction or a series
      of related transactions (other than in one or a series of Excluded
      Transactions), by the Corporation and/or its subsidiaries of all or
      substantially all of the businesses, assets, properties and liabilities
      attributed to the WorldCom Group, the Corporation shall, on or prior to
      the 120th Trading Day after the Disposition Date, as determined by the
      board of directors in its sole discretion:

                  (1) provided that there are funds legally available for the
            purpose:

                        (a) subject to compliance with Section 1, pay to the
                  holders of the shares of WorldCom Stock a distribution pro
                  rata in accordance with the number of shares of WorldCom Stock
                  held by each such holder in cash and/or securities or other
                  property having a Fair Value as of the Disposition Date in the
                  aggregate equal to the product of:

                              (x) the Outstanding Interest Fraction with respect
                        to WorldCom Stock as of the record date for determining
                        holders entitled to receive such distribution; and

                              (y) the Fair Value as of the Disposition Date of
                        the Net Proceeds of such Disposition; or

                        (b) (I) subject to the last sentence of this Section
                  4(A)(i), if such Disposition involves all (not merely
                  substantially all) of the businesses, assets, properties and
                  liabilities attributed to the WorldCom Group, redeem or
                  exchange as of the Redemption Date, determined as provided by
                  Section 4(G)(iii)(2), all outstanding shares of WorldCom Stock
                  in


                                      6


                  exchange for, on a pro rata basis, cash and/or securities
                  (other than shares of a series of common stock) or other
                  property having a Fair Value as of the Disposition Date in the
                  aggregate equal to the product of:

                        to WorldCom Stock as of the record date for determining
                        holders entitled to receive such distribution; and

                              (y) the Fair Value of the Disposition Date of the
                        Net Proceeds of such Disposition; or

                        (II) subject to the last sentence of this Section
                  4(A)(i), if such Disposition involves substantially all (but
                  not all) of the businesses, assets, properties and liabilities
                  attributed to the WorldCom Group, redeem or exchange as of the
                  Redemption Date, determined as provided by Section
                  4(G)(iv)(2), the number of whole shares of WorldCom Stock
                  equal to the lesser of:

                              (x) the number of shares of WorldCom Stock
                        outstanding; and

                              (y) such number of shares of WorldCom Stock as
                        have in the aggregate an average Market Value during the
                        period of ten consecutive Trading Days beginning on the
                        51st Trading Day immediately succeeding the Disposition
                        Date closest to the product of:

                              respect to WorldCom Stock as of the record date
                              for determining such shares selected for
                              redemption or exchange; and

                                    (BB) the Fair Value as of the Disposition
                              Date of the Net Proceeds of such Disposition,

in exchange for, on a pro rata basis, cash and/or securities (other than shares
of a series of the Corporation's common stock) or other property having a Fair
Value as of the Disposition Date in the aggregate equal to such product; or

            (2) declare that each outstanding share of MCI Stock shall be
      converted as of the Conversion Date, determined as provided by Section
      4(G)(v)(2), into a number of fully paid and nonassessable shares of
      WorldCom Stock, equal to the ratio, rounded to the nearest 1/10,000
      (.0001), of the average Market Value of one share of MCI Stock over the
      period of ten consecutive Trading Days beginning on the 51st Trading Day
      following the Disposition Date to the average Market Value of one share of
      WorldCom Stock during such ten-Trading Day period.

Notwithstanding the foregoing provisions of this Section 4(A)(i), the
Corporation shall redeem or exchange shares of WorldCom Stock as provided by
Section 4(A)(i)(1)(b)(I) or (II) only if the


                                      7


amount to be paid in redemption or exchange of such stock is less than or equal
to the WorldCom Group Available Distribution Amount as of the Redemption Date.

            (ii) For purposes of this Section 4(A):

                  (1) as of any date, "substantially all of the businesses,
            assets, properties and liabilities" attributed to the WorldCom Group
            shall mean a portion of such businesses, assets, properties and
            liabilities that represents at least 80% of the Fair Value of the
            businesses, assets, properties and liabilities attributed to the
            WorldCom Group as of such date;

                  (2) in the case of a Disposition of the businesses, assets,
            properties and liabilities attributed to the WorldCom Group in a
            series of related transactions, such Disposition shall not be deemed
            to have been consummated until the consummation of the last of such
            transactions; and

                  (3) the board of directors may pay any distribution or
            redemption price referred to in Section 4(A)(i)(1) in cash,
            securities (other than shares of a series of the Corporation's
            common stock) or other property, regardless of the form or nature of
            the proceeds of the Disposition.

                  (iii) After the payment of any distribution or redemption
            price with respect to the WorldCom Stock as provided for by Section
            4(A)(i)(l), the board of directors may declare that each share of
            WorldCom Stock remaining outstanding shall be converted as of a
            Conversion Date, determined as provided by Section 4(G)(v)(2), into
            a number of fully paid and nonassessable shares of MCI Stock equal

            exercises such Convertible Securities.

            (vii) Any notice required to be given each holder of shares of
      common stock or Convertible Securities pursuant to this Section 4(G) shall
      be sent by first-class mail, postage prepaid, to each such holder at such
      holder's address as the same appears on the


                                      20


      transfer books of the Corporation or the Corporation's transfer agent or
      registrar on the record date fixed for such notice. Neither the failure to
      mail any notice required by this Section 4(G) to any particular holder of
      the common stock or of Convertible Securities nor any defect therein shall
      affect the sufficiency thereof with respect to any other holder of
      outstanding shares of the common stock or of Convertible Securities or the
      validity of any such redemption or conversion.

            (viii) If less than all of the outstanding shares of either series
      of common stock are to be redeemed pursuant to Section 4(A)(i)(1)(b)(II)
      (in the case of WorldCom Stock) or Section 4(B)(i)(1)(b)(Il) (in the case
      of MCI Stock), the shares to be redeemed by the Corporation shall be
      selected from among the holders of shares of such series of common stock
      outstanding at the close of business on the record date for such
      redemption on a pro rata basis among all such holders or by lot or by such
      other method as may be determined by the Board of Directors to be
      equitable.

            (ix) The Corporation shall not be required to issue or deliver
      fractional shares of any capital stock or of any other securities to any
      holder of either series of common stock upon any dividend or other
      distribution, redemption or conversion pursuant to this Section 4. If more
      than one share of a series of common stock shall be held at the same time
      by the same holder, the Corporation may aggregate the number of shares of
      any capital stock that shall be issuable or any other securities or
      property that shall be distributable in respect of such series to such
      holder upon any dividend or other distribution, redemption or conversion
      (including any fractional shares). If there are fractional shares of any
      capital stock or of any other securities remaining to be issued or
      distributed to the holders of any series of common stock, the Corporation
      shall, if such fractional shares are not issued or distributed to the
      holder, pay cash in respect of such fractional shares in an amount equal
      to the Fair Value thereof (without interest).

            (x) No adjustments in respect of dividends shall be made upon the
      redemption or conversion of shares of either series of common stock;
      provided, however, that if the Redemption Date or Conversion Date, as the
      case may be, with respect to shares of either series of common stock shall
      be subsequent to the record date for the payment of a dividend or other
      distribution thereon or with respect thereto, the holders of such series
      of common stock at the close of business on such record date shall be
      entitled to receive the dividend or other distribution payable on or with
      respect to such shares on the date set for payment of such dividend or
      other distribution, in each case without interest, notwithstanding the
      subsequent conversion or redemption of such shares.

            (xi) Before any holder of shares of either series of common stock
      shall be entitled to receive any cash payment and/or certificates or
      instruments representing shares of any capital stock and/or other
      securities or property to be distributed to such holder with respect to
      such series of common stock pursuant to this Section 4, such holder shall
      surrender at such place as the Corporation shall specify certificates for
      such shares of the common stock, properly endorsed or assigned for
      transfer (unless the Corporation shall waive such requirement). The
      Corporation shall as soon as practicable after receipt of certificates
      representing such shares of the common stock deliver to the person for
      whose account such shares of the common stock were so surrendered, or to
      such person's


                                      21


      nominee or nominees, the cash and/or the certificates or instruments
      representing the number of whole shares of the kind of capital stock
      and/or other securities or property to which such person shall be entitled
      as aforesaid, together with any payment in respect of fractional shares
      contemplated by Section 4(G)(ix), in each case without interest. If less
      than all of the shares of either series of common stock represented by any
      one certificate are to be redeemed, the Corporation shall issue and
      deliver a new certificate for the shares of such series of common stock
      not redeemed.

            (xii) From and after any applicable Redemption Date or Conversion
      Date, as the case may be, all rights of a holder of shares of either
      series of common stock that were converted or redeemed shall cease except
      for the right, upon surrender of the certificates representing such shares
      of the common stock as required by Section 4(G)(xi), to receive the
      certificates representing shares of the kind and amount of capital stock
      and/or other securities or property for which such shares were redeemed or
      converted, together with any payment in respect of fractional shares
      contemplated by Section 4(G)(ix) and rights to dividends as provided in
      Section 4(G)(x), in each case without interest. No holder of a certificate
      that immediately prior to the applicable Redemption Date or Conversion
      Date represented shares of a series of common stock shall be entitled to
      receive any dividend or other distribution or interest payment with
      respect to shares of any kind of capital stock or other security or
      instrument for which such series of common stock was redeemed or converted
      until the surrender as required by this Section 4 of such certificate in
      exchange for a certificate or certificates or instrument or instruments
      representing such capital stock or other security. Upon such surrender,
      there shall be paid to the holder the amount of any dividends or other
      distributions (without interest) which theretofore became payable on any
      class or series of capital stock of the Corporation as of a record date
      after the Conversion Date, but that were not paid by reason of the
      foregoing, with respect to the number of whole shares of the kind of
      capital stock represented by the certificate or certificates issued upon
      such surrender. From and after a Redemption Date or Conversion Date, the
      Corporation shall be entitled, however, to treat the certificates for a
      series of common stock that have not yet been surrendered for conversion
      as evidencing the ownership of the number of whole shares of the kind or
      kinds of capital stock of the Corporation for which the shares of such
      series of common stock represented by such certificates shall have been
      converted, notwithstanding the failure to surrender such certificates.

            (xiii) The Corporation shall pay any and all documentary, stamp or
      similar issue or transfer taxes that may be payable in respect of the
      issuance or delivery of any shares of capital stock and/or other
      securities upon redemption or conversion of shares of any series of common
      stock pursuant to this Section 4. The Corporation shall not, however, be
      required to pay any tax that may be payable in respect of any transfer
      involved in the issuance or delivery of any shares of capital stock and/or
      other securities in a name other than that in which the shares of such
      series of common stock so redeemed or converted were registered, and no
      such issuance or delivery shall be made unless the person requesting such
      issuance or delivery has paid to the Corporation the amount of any such
      tax or has established to the satisfaction of the Corporation that such
      tax has been paid.


                                       22


            (xiv) The board of directors may establish such rules and
      requirements to facilitate the effectuation of the transactions
      contemplated by this Section 4 as the Board of Directors shall determine
      to be appropriate.

            Section 5. Inter-Group Interest and Related Transfers Between and
Among Groups.

            (A) Changes in Inter-Group Interest. The Number of Shares Issuable
with Respect to the Inter-Group Interest in any Issuer Group held by any Holder
Group shall from time to time be:

            (i) adjusted, if before such adjustment such number is greater than
      zero, as determined by the board of directors to be appropriate to reflect
      equitably any subdivision (by stock split or otherwise) or combination (by
      reverse stock split or otherwise) of the series of common stock related to
      such Issuer Group;

            (ii) decreased (but to not less than zero), if before such
      adjustment such number is greater than zero, by action of the board of
      directors by:

                  (1) such the number of shares of the series of common stock
            related to such Issuer Group issued or sold by the Corporation that,
            immediately prior to such issuance or sale, was included in the
            Number of Shares Issuable with Respect to the Inter-Group Interest
            in such Issuer Group held by such Holder Group;

                  (2) the number of shares of such series of common stock issued
            upon the conversion, exchange or exercise of any Convertible
            Securities that, immediately prior to the issuance or sale of such
            Convertible Securities, were included in the Number of Shares
            Issuable with Respect to the Inter-Group Interest in such Issuer
            Group held by such Holder Group;

                  (3) the number of shares of such series of common stock issued
            by the Corporation as a share dividend or in connection with any
            reclassification or exchange of shares, including an exchange offer,
            to holders of the series of common stock related to such Holder
            Group;

                  (4) the number of shares of such series of common stock issued
            upon the conversion, exchange or exercise of any Convertible
            Securities issued by the Corporation as a distribution or in
            connection with any reclassification or exchange of shares,
            including an exchange offer, to holders of the series of common
            stock related to such Holder Group;

                  (5) the number of shares (rounded, if necessary, to the
            nearest whole number) of such series of common stock equal to the
            product of (x) the number of shares of such series of common stock
            redeemed or exchanged pursuant to Section 4(A)(i)(l)(b)(I) or (II)
            or Section 4(B)(i)(1)(b)(I) or (II) and (y) a fraction (which may be
            greater than one), the numerator of which is the Number of Shares
            Issuable with Respect to the Inter-Group Interest in such Issuer
            Group held by


                                       23


            such Holder Group, and the denominator of which is the number of
            shares of series of common stock outstanding, in each case, on the
            record date for determining such shares selected for such redemption
            or exchange; and

                  (6) the number of shares (rounded, if necessary, to the
            nearest whole number) of such series of common stock equal to the
            quotient of (x) the aggregate Fair Value as of the date of transfer
            of (i) businesses, assets (including cash) or properties transferred
            from such Issuer Group to such Holder Group or (ii) liabilities
            transferred from such Holder Group to such Issuer Group, in either
            case, for the purpose of reducing the Number of Shares Issuable with
            Respect to the Inter-Group Interest in such Issuer Group held by
            such Holder Group, divided by (y) the average Market Value of one
            share of the series of common stock related to such Issuer Group
            during the period of 20 consecutive Trading Days ending on the date
            of such contribution or transfer,

            (iii) increased by action of the Board of Directors by:

                  (1) the number of outstanding shares of the series of common
            stock related to such Issuer Group repurchased by the Corporation
            for consideration that was attributed as an asset as provided by
            Section 7(O) or 7(CC) to such Holder Group;

                  (2) the number of shares of such series of common stock equal
            to the product of (x) the quotient of (i) the number of shares of
            such series of common stock issued by the Corporation as a share
            dividend or in connection with any reclassification to holders of
            such series of common stock divided by (ii) the number of shares of
            such series of common stock outstanding on the record date for such
            share dividend or reclassification and (y) the Number of Shares
            Issuable with Respect to the Inter-Group Interest in such Issuer
            Group on such record date;

                  (3) the number of shares of such series of common stock into
            or for which Convertible Securities attributed as a liability to, or
            equity interest in, such Issuer Group are deemed converted,
            exchanged or exercised by such Holder Group pursuant to Section
            5(C); and

                  (4) the number of shares (rounded to the nearest whole number)
            of such series of common stock equal to the quotient of (x) the
            aggregate Fair Value as of the date of (i) contribution of
            businesses, assets (including cash) or properties transferred from
            such Holder Group to such Issuer Group or (ii) transfer of
            liabilities from such Issuer Group to such Holder Group, in
            consideration of an increase in the Number of Shares Issuable with
            Respect to the Inter-Group Interest in such Issuer Group held by
            such Holder Group, divided by (y) the average Market Value of one
            share of the series of common stock related to such Issuer Group
            during the period of 20 consecutive Trading Days ending on the date
            of such contribution or transfer;


                                       24


            (iv) increased or decreased under such other circumstances as the
      board of directors determines appropriate to reflect the economic
      substance of any other event or circumstance; provided that, in each case,
      the adjustment shall be made in a manner that is fair and equitable to
      holders of common stock and intended to reflect the relative economic
      interest in one Group held by the other Group.

            (B) Reattribution Upon Certain Distributions.

            (i) If the Corporation shall make a distribution with respect to
      shares of either series of common stock (payable in consideration other
      than securities of the Corporation), effective on the payment date of such
      distribution, the Holder Group holding an Inter-Group Interest in the
      Issuer Group in respect of which such distribution has been paid shall be
      attributed as an asset an amount of assets or properties, previously
      attributed to such Issuer Group, of the same kind as were paid in such
      distribution, as have a Fair Value on the record date for such
      distribution equal to the product of:

                  (1) the Fair Value on such record date of the aggregate
            distribution to holders of shares of such series of common stock;
            and

                  (2) a fraction (which may be greater than one), the numerator
            of which is equal to the Number of Shares Issuable with Respect to
            the Inter-Group Interest in such Issuer Group held by such Holder
            Group and the denominator of which is equal to the number of
            outstanding shares of the series of common stock related to such
            Issuer Group, in each case, on the record date for such
            distribution.

            (ii) If the Corporation shall make a distribution with respect to
      shares of either series of common stock payable in securities of the
      Corporation that are attributed to the related Issuer Group as a liability
      of, or an equity interest in, such Issuer Group, the Holder Group holding
      an Inter-Group Interest in such Issuer Group shall be attributed as assets
      the number or amount of such securities equivalent to such liability or
      equity interest that is equal to the product of:

                        (x) the number or amount of securities so distributed to
                  holders of outstanding shares of the series of common stock
                  related to such Issuer Group; and

                        (y) a fraction (which may be greater than one), the
                  numerator of which is equal to the Number of Shares Issuable
                  with Respect to the Inter-Group Interest in such Issuer Group
                  held by such Holder Group and the denominator of which is
                  equal to the number of outstanding shares of the series of
                  common stock related to such Issuer Group, in each case, on
                  the record date for such dividend or other distribution;

and, to the extent interest is or distributions are paid on the securities so
distributed, the Holder Group shall be attributed at the time of such payment a
corresponding ratable amount of the kind of assets paid as such interest or
distributions as would have been paid in respect of such securities so deemed to
be held by such Holder Group if such securities were outstanding.


                                      25


            (C) Deemed Conversion of Certain Convertible Securities Held by the
Holder Group. To the extent Convertible Securities are paid as a distribution to
the holders of either series of common stock, the Corporation may (in addition
to making an adjustment pursuant to Section 5(B)(ii)) when at any time such
Convertible Securities are convertible into or exchangeable or exercisable for
shares of such series of common stock, treat such Convertible Securities as
converted, exchanged or exercised for purposes of determining the increase in
the Number of Shares Issuable with Respect to the Inter-Group Interest in such
Issuer Group pursuant to Section 5(A)(iii)(3), and must do so to the extent such
Convertible Securities are mandatorily converted, exchanged or exercised (and to
the extent the terms of such Convertible Securities require payment of
consideration for such conversion, exchange or exercise, such Holder Group shall
then no longer be attributed as an asset an amount of the kind of assets or
properties required to be paid as such consideration for the amount of
Convertible Securities deemed converted, exchanged or exercised (and such Issuer
Group shall be attributed such assets or properties)), in which case, from and
after such time, the shares of common stock into or for which such Convertible
Securities were so considered converted, exchanged or exercised shall be deemed
held by such Holder Group and such Convertible Securities shall no longer be
deemed to be held by such Holder Group. A statement setting forth the election
to effectuate any such deemed conversion, exchange or exercise of Convertible
Securities and the assets or properties, if any, to be attributed to the other
Group in consideration of such conversion, exchange or exercise shall be filed
in the records of the actions of the board of directors and, upon such filing,
such deemed conversion, exchange or exercise shall be effectuated.

            (D) Permitted Inter-Group Interests. Either Group may hold an
Inter-Group Interest in the other Group; provided that neither Group may hold an
Inter-Group Interest in the other Group if, immediately after the creation of
such Inter-Group Interest, the Groups would hold Inter-Group Interests in each
other.

            Section 6. Application of the Provisions of Section A of Article 4.

            (A) Certain Determinations by the Board of Directors. The board of
directors shall make such determinations with respect to (a) the businesses,
assets, properties and liabilities to be attributed to the WorldCom Group and
the MCI Group, (b) the application of the provisions of these Second Amended and
Restated Articles of Incorporation to transactions to be engaged in by the
Corporation and (c) the voting powers, preferences, designations, rights,
qualifications, limitations or restrictions of either series of common stock or
of the holders thereof, as may be or become necessary or appropriate to the
exercise of, or to give effect to, such voting powers, preferences,
designations, rights, qualifications, limitations or restrictions, including,
without limiting the foregoing, the determinations referred to in this Section
6. A record of any such determination shall be filed with the records of the
actions of the board of directors.

            (i) Upon any acquisition by the Corporation or its subsidiaries of
      any businesses, assets or properties, or any assumption of liabilities,
      outside of the ordinary course of business of either Group, the board of
      directors shall determine whether such businesses, assets, properties and
      liabilities (or an interest therein) shall be for the benefit of the
      WorldCom Group or the MCI Group or both and, accordingly, shall be
      attributed to such Group or Groups, in accordance with Section 7(O) or
      7(CC), as the case may be.


                                       26


            (ii) Upon any issuance of shares of any series of common stock at a
      time when the Number of Shares Issuable with Respect to the Inter-Group
      Interest in the Issuer Group related to such series is greater than zero,
      the Board of Directors shall determine, based on the use of the proceeds
      of such issuance and any other relevant factors, whether all or any part
      of the shares of such series so issued shall reduce such Number of Shares
      Issuable with Respect to the Inter-Group Interest.

            (iii) Upon any issuance by the Corporation or any subsidiary thereof
      of any Convertible Securities that are convertible into or exchangeable or
      exercisable for shares of either series of common stock, if at the time
      such Convertible Securities are issued the Number of Shares Issuable with
      Respect to the Inter-Group Interest in the Issuer Group related to such
      series is greater than zero, the board of directors shall determine, based
      on the use of the proceeds of such issuance and any other relevant
      factors, whether, upon conversion, exchange or exercise thereof, the
      issuance of shares of such series of common stock pursuant thereto shall,
      in whole or in part, reduce such Number of Shares Issuable with Respect to
      the Inter-Group Interest.

            (iv) Upon any issuance of any shares of preferred stock (or stock
      other than common stock) of any series, the board of directors shall
      attribute, based on the use of proceeds of such issuance of shares of
      preferred stock (or stock other than common stock) in the business of
      either Group and any other relevant factors, the shares so issued entirely
      to the WorldCom Group, entirely to the MCI Group, or partly to both
      Groups, in such proportion as the Board of Directors shall determine.

            (v) Upon any redemption or repurchase by the Corporation or any
      subsidiary thereof of shares of preferred stock (or stock other than
      common stock) of any class or series or of other securities or debt
      obligations of the Corporation, the board of directors shall determine,
      based on the property used to redeem or purchase such shares, other
      securities or debt obligations, which, if any, of such shares, other
      securities or debt obligations redeemed or repurchased shall be attributed
      to the WorldCom Group, to the MCI Group, or both, and, accordingly, how
      many of the shares of such series or class of preferred stock (or stock
      other than common stock) or of such other securities, or how much of such
      debt obligations, that remain outstanding, if any, are thereafter
      attributed to each Group.

            (vi) Upon any transfer to either Group of businesses, assets,
      properties or liabilities attributed to either Group to the other Group,
      the consideration therefor to be attributed to the transferring Group in
      exchange therefor, including, without limitation, cash, securities or
      other property of such other Group or, if permitted by Section 5(D), a
      decrease or an increase in the Number of Shares of Shares Issuable with
      Respect to the Inter-Group Interest in such other Group, as described in
      Section 5(A)(ii)(6) or Section 5(A)(iii)(4).

            (B) Certain Determinations Not Required. Notwithstanding the
foregoing provisions of this Section 6 or any other provision in these Second
Amended and Restated Articles of Incorporation, at any time when there are not
outstanding more than one series of


                                       27


common stock (or Convertible Securities convertible into or exchangeable or
exercisable for more than one series of common stock), the Corporation need not:

            (i) attribute any of the businesses, assets, properties or
      liabilities of the Corporation or any of its subsidiaries to the WorldCom
      Group or the MCI Group; or

            (ii) make any determination required in connection therewith, nor
      shall the board of directors be required to make any of the determinations
      otherwise required by this Section A of Article 4,

and in such circumstances the holders of the shares of WorldCom Stock and MCI
Stock outstanding, as the case may be, shall (unless otherwise specifically
provided in these Second Amended and Restated Articles of Incorporation) be
entitled to all the voting powers, preferences, designations, rights,
qualifications, limitations or restrictions of common stock of the Corporation.

            (C) Board Determinations Binding. Any determinations made in good
faith by the board of directors of the Corporation under any provision of this
Section 6 or otherwise in furtherance of the application of this Article 4A
shall be final and binding on all shareholders.

            Section 7. Certain Definitions and Rules of Interpretation. As used

in the plural and vice versa), unless the context otherwise requires. For
purposes of this Section A of Article 4, the WorldCom Stock, when issued, shall
be considered issued in respect of or related to the WorldCom Group, and the MCI
Stock, when issued, shall be considered issued in respect of or related to the
MCI Group. As used in this Section 7, a "contribution" or "transfer" of
businesses, assets, properties or liabilities from one Group to the other shall
refer to the reattribution of such businesses, assets, properties or liabilities
from the contributing or transferring Group to the other Group and correlative
phrases shall have correlative meanings.

            (A) "Available Distribution Amount" shall mean, as the context

that are convertible into or exchangeable or exercisable for shares of the
series of common stock subject to such conversion requirements pursuant to
Section 4(G)(v).

            (C) "Convertible Securities" shall mean, at any time, any securities
of the Corporation or of any subsidiary thereof (other than shares of common
stock), including warrants and options, outstanding at such time that by their
terms are convertible into or exchangeable or exercisable for or evidence the
right to acquire any shares of any series of common stock, whether convertible,
exchangeable or exercisable at such time or a later time or only upon the


                                       28


occurrence of certain events, but in respect of antidilution provisions of such
securities only upon the effectiveness thereof.

or stock or otherwise) of businesses, assets (including stock, other securities
and goodwill), properties or liabilities.

            (E) "Disposition Date," with respect to the WorldCom Group or the
MCI Group, shall mean the date of consummation of the Disposition of such Group
referred to in Section 4(A)(i) or Section 4(C)(i), as applicable.

or substantially all of the businesses, assets, properties and liabilities
attributed to the WorldCom Group or the MCI Group, as the case may be, in a
transaction or series of related transactions that result in the Corporation,

consideration of such businesses, assets, properties and liabilities primarily

change in law by an applicable legislative committee or the chair thereof),
regardless of whether such amendment, clarification, change or proposed change

more than an insubstantial risk that:

            (i) for tax purposes, any issuance of WorldCom Stock or MCI Stock

            (ii) the issuance or existence of WorldCom Stock or MCI Stock would

For purposes of rendering such opinion, tax counsel shall assume that any
legislative or administrative proposals will be adopted or enacted as proposed.

      other than any businesses, assets, properties and liabilities attributed

                  for the WorldCom Group to pay debts attributed to the WorldCom
                  Group as they become due in the usual course of business; and
