        Replacement Service and when applicable, a reconfiguration of the
        Original Service which is available, i.e., cities served prior to the
        upgrade continue to be served by the Replacement Service following the
        upgrade.
D.      Customer will be liable for costs, if any, reasonably incurred by
        WorldCom from third parties (e.g., Local Access providers or
        interconnecting carriers) as a result of such cancellation, provided
        WorldCom notifies Customer of such costs within a reasonable time
        following receipt of Customer's Service Order to effect a cancellation
        and obtain Replacement Service.
E.      Replacement Service shall have a similar Minimum Monthly Commitment as

convenience prior to the term, the following early termination charges

Commitment Period through the expiration of the first year of the
Commitment Period plus fifty percent (50%) of the balance of such Minimum
Monthly Commitment times the remainder of the Commitment Period beyond the

Monthly Commitment times the number of months (or pro-rata portion
thereof) remaining in the Commitment period.

subject to an ICB arrangement, then the charge will be an amount equal to
the total cancellation charges incurred by WorldCom, in addition to
termination charges set forth in "A" or "B" above.

D.      Customer is also liable for any charges, expenses, fees or penalties
incurred by WorldCom or its affiliated companies due to cancellation of
Local Access plus any costs, expenses or additional charges reasonably
incurred by WorldCom on behalf of Customer as Customer's agent.

Circuit comprising Qualifying IXC Service of the Revenue Plan is twelve
(12) months, unless the aforementioned Circuit is upgraded to a Service of
equal or greater monthly recurring charge and such Circuit has been
installed for no less than a six (6) month period.  The Customer is also
