       FOR VALUE RECEIVED, the undersigned (the "Borrower") hereby
unconditionally promises to pay to the order of WorldCom, Inc., a Georgia

in immediately available funds, the principal sum of (a) FOUR HUNDRED EIGHT

PLUS (b) the amount of any payments made after the date hereof by the Lender

and on the dates set forth below:

                      Date                             Amount
                      ----                             ------

                 April 29, 2003                $25,000,000

                 April 29, 2004                $25,000,000

                 April 29, 2005                $75,000,000

                 April 29, 2007                All remaining principal

       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, payable on each date of repayment of principal set forth above, 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 Revolving Credit
Agreement among the Lender, Bank of America, N.A. and JPMorgan Chase Bank, as
Co-Administrative Agents, and the other Lenders identified therein dated as of
June 8, 2001, as the same may be amended or replaced; provided, however, that
following any demand for payment, the Borrower promises to pay interest on the
unpaid balance hereunder, compounded monthly, at the Default Rate, as defined
herein, payable from time to time upon demand. 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 Borrower may at his option, at any time, prepay this Note, in whole
or in part, without premium or penalty. Any such optional prepayment shall be
applied to reduce the then remaining installments of principal in the direct
order of maturity; provided that any return of all or any portion of the
Lender's approximately $36.5 million deposit (the "Deposit") supporting the B of
A (as defined below) letter of credit shall be applied to the final principal
payment and not to any earlier payment. For the avoidance of doubt, any payment
or deposit by the Lender simultaneous with or after the date of such return
relating to the B of A letter of credit, any alternative or replacement letter
of credit or similar arrangement shall be added to the principal amount of this
Note when paid or advanced; provided that such alternative or replacement letter
of credit or similar arrangement is reasonably acceptable to the Borrower.

       The Borrower hereby agrees not to borrow after the date hereof any amount
from Bank of America, N.A. ("B of A") that would be covered by (i) the Limited
Guaranty, dated as of November 14, 2000 (as amended, supplemented or otherwise
modified from time to time, the "Prior Guaranty"), executed by the Lender for
the benefit of B of A or (ii) the Limited Guaranty, dated as of February 12,
2001, as modified by that certain First Modification and Reaffirmation of
Limited Guaranty, dated as of January 25, 2002 (and as further amended,
supplemented or otherwise modified from time to time, the "New Guaranty" and,
together with the Prior Guaranty, the "Guaranty"), executed by the Lender for
the benefit of B of A.

       All principal and accrued interest under this Note shall become
immediately due and payable upon the death of the Borrower or upon demand by the
Lender (or, in the case of an event specified in clause (iv) below,
automatically without notice) if any one of the following events shall occur and
be continuing (each, an "Event of Default"): (i) the Borrower shall fail to pay
any principal or interest under this Note when due, (ii) the Borrower shall
default in the observance or performance of any agreement contained herein,
(iii) the Borrower shall default in the observance or performance of any
agreement contained in the Separation Agreement, dated as of April 29, 2002, or
(iv) the Borrower shall become, or there shall be commenced against the Borrower
a case to declare him, bankrupt. If any amount of this Note is not paid when
due, 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.

       This Note shall constitute a Promissory Note within the meaning and
subject to the provisions of that certain letter agreement dated April 2, 2002,
as the same may be amended or otherwise modified, between the Borrower and the
Lender.



       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.
