                                PROMISSORY NOTE
                                ---------------

                                                            Clinton, Mississippi
$25,000,000                                                     November 1, 2000

     FOR VALUE RECEIVED, the undersigned (the "Borrower") hereby unconditionally
promises to pay to the order of WorldCom, Inc., a Georgia corporation (the
"Lender"), in lawful money of the United States of America and in immediately
available funds, the principal sum of Twenty-Five Million Dollars ($25,000,000)
or such lesser amount as may be outstanding hereunder.  The aforesaid principal
sum is to be the maximum sum available hereunder and may be taken in such
amounts and at such times as the undersigned requests prior to demand for
payment hereunder.  The Borrower further promises to pay interest on the
outstanding balance under this Note, compounded monthly, from the date hereof
until payment in full of this Note, at a fluctuating rate of interest (the
"Normal Rate") equal to the Eurodollar Rate applicable to each one-month
Interest Period commencing on the date hereof plus the Applicable Margin during
the corresponding period applicable to Eurodollar Rate Borrowings by the Lender
pursuant to that certain Amended and Restated 364-Day Revolving Credit and Term
Loan Agreement among the Lender, Bank of America, N.A., as Administrative Agent,
and the other Lenders identified therein dated as of August 5, 1999, as amended;
provided, however, that following demand for payment, the Borrower promises to
pay interest on the unpaid balance hereunder, compounded monthly, at the Default
Rate, as defined herein.  The "Default Rate" shall be a fluctuating rate of
interest equal to the sum of the otherwise applicable Normal Rate plus three
percent (3%) per annum.  Upon each change in the applicable Normal Rate, the
Default Rate shall simultaneously change to correspond with such change in the
Normal Rate.  Interest shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

     The principal and accrued interest under this Note are payable on demand.
If this Note is not paid upon demand, the Borrower hereby promises to pay all
costs of collection, including but not limited to the fees and expenses of an
attorney and court costs, in addition to the full amount due hereon.

     Interest shall be due and payable under this Note at the Normal Rate or the
Default Rate, as provided herein, after as well as before demand, default and
judgment, notwithstanding any applicable statutory judgment rate of interest.
If any interest payment or other charge or fee payable hereunder exceeds the
maximum amount then permitted by applicable law, then the Borrower shall pay the
maximum amount then permitted by applicable law.

     The Borrower hereby waives presentment, protest and notice of demand,
presentment, protest and nonpayment.

     This Note shall be interpreted and the rights and liabilities of the
parties hereto shall be determined in accordance with the internal laws (as
opposed to the conflicts of law provisions) and decisions of the State of
Mississippi and the Borrower hereby consents to the jurisdiction of the courts
of or in the State of Mississippi in connection with any dispute, controversy,
collection

action or other matter relating to or arising out of this Note.
Whenever possible each provision of this Note shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Note shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining provisions
of this Note.  Whenever in this Note reference is made to the Borrower or the
Lender, such reference shall be deemed to include, in the case of the Borrower,
a reference to his heirs and legal representatives and, in the case of the
Lender, its successors and assigns.  The provisions of this Note shall be
binding upon and shall inure to the benefit of such heirs, legal
representatives, successors and assigns.

Dear Bernie:

     This is to confirm the agreement whereby WorldCom, Inc. (the "Company")
will provide a Limited Guaranty to Bank of America, N.A. (the "Bank") regarding
certain of your liabilities to the Bank (as the same may be amended, modified,
supplemented or replaced, the "Guaranty").  This agreement also relates to
security for your obligations hereunder and under those certain Promissory Notes
from you to the Company dated September 8, 2000 and November 1, 2000 (as the
same may be amended, modified, supplemented or replaced, the "Promissory Notes")
covering amounts loaned or to be loaned to you for payment of certain of your
obligations to institutional lenders which are secured by shares of Company
stock held by you.  For valuable consideration, you hereby agree as follows:

     1.  Indemnity.  You shall indemnify and hold harmless the Company for any
         ---------
amounts expended, losses, damages, costs, claims or expenses (including, but not
limited to, court costs and attorneys' fees) under or arising out of the
Guaranty, this agreement or the Promissory Notes.

     2.  Pledge.  To the extent not prohibited by any covenant or agreement by
         ------
you in favor of the Bank or other lender, in order to secure your performance
hereunder and payment of amounts due under the Promissory Notes (the
"Liabilities"), you hereby grant, or upon release of any such prohibition you
shall grant, to the Company a security interest under Article 9 of the Uniform
Commercial Code as currently effective in the State of Mississippi in the shares
of stock in the Company owned by you, whether now owned or hereafter acquired by
you, and all proceeds thereof and amounts or other securities or property
derived therefrom (the "Collateral").  Such security interest shall be
subordinate to the rights of the Bank and other lenders pursuant to agreements
or documents in effect on the date hereof, or any renewals, replacements,
amendments, modifications or extensions thereof (the "Prior Rights").  You agree
to keep the Collateral free from any lien, security interest or encumbrance
other than those in favor of the Company, arising out of the Prior Rights or to
which the Company consents in writing.  Upon default by you under the terms of
this agreement or either of the Promissory Notes, the Company may exercise the
rights and pursue the remedies provided under Article 9 of the Uniform
Commercial Code as currently effective in, or as hereafter amended by, the State
of Mississippi, including but not limited to exercising all voting rights with
respect to the Collateral, collecting all dividends and other distributions with
respect to the Collateral, and selling the Collateral at any public or private
sale, at the Company's option, without advertisement.  The Company may bid and
become a purchaser at any such sale, and upon any such sale the Company shall
collect, receive, and hold and apply the proceeds as provided herein.  If notice
of intended disposition is required by law, such notice, if mailed, shall be
deemed reasonably and properly given if mailed to your address appearing on the
records of the Company at least five days before the time of such disposition.
The proceeds from any such sale or action shall be applied first to the payment
of all legal and other costs and expenses incurred in connection with the sale
or action and next to the payment of the Liabilities, as determined by the
Company.  The balance, if

any, of such proceeds remaining after such application shall be paid to you. If
the proceeds of any such sale or action are insufficient to pay in full the
amounts specified above, you shall remain liable for such deficiency.

     3.  Further Assurances.  You agree to perform all acts and do all things
         ------------------
which the Company may request, now or hereafter, in order to evidence, preserve
or protect its rights and the creation, attachment or perfection of the security
interest granted or to be granted hereunder including, without limitation,
execution and delivery of one or more promissory notes evidencing your
obligations arising out of any advance under the Guaranty and delivery of stock
certificate(s) with appropriate stock powers in order to perfect the Company's
security interest in the Collateral.

     4.  Miscellaneous.  This agreement shall be interpreted and the rights and
         -------------
liabilities of the parties hereto shall be determined in accordance with the
internal laws (as opposed to the conflicts of law provisions) and decisions of
the State of Mississippi and you hereby consent to the jurisdiction of the
courts of or in the State of Mississippi in connection with any dispute,
controversy, action or other matter relating to or arising out of this
agreement.  Whenever possible each provision of this agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this agreement shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this agreement.  This agreement shall be binding
upon you and your heirs and legal representatives and shall inure to the benefit
of the Company and its successors and assigns.  The powers, rights, and remedies
of the Company under this agreement are cumulative and are not exclusive of any
other power, right or remedy that the Company otherwise may have.  Any single or
partial exercise or pursuit of any power, right or remedy under this agreement
by the Company shall not preclude other or further exercise or pursuit thereof
or the exercise or pursuit of any other power, right or remedy.  The Company's
rights and remedies under this agreement shall be unaffected by any change in
the provisions of any agreement, instrument, or document evidencing or affecting
any of the Liabilities, by any extension of time for payment or performance of
any of the Liabilities or by any partial or full release of any security for
payment or performance of any of the Liabilities.  No delay by the Company in
exercising or pursuing any power, right or remedy under this agreement shall
operate as a waiver thereof, and no failure by the Company to exercise or pursue
any power, right or remedy shall prevent the Company from exercising the same in
the future.
