         (a)     For purposes of determining the Applicable Margin, (i) if
                 neither Moody's nor S&P shall have in effect a rating for
                 Index Debt (other than by reason of the circumstances referred
                 to in the last sentence of this definition), then both such
                 rating agencies will be deemed to have established ratings for
                 Index Debt in Category 5; (ii) if only one of Moody's or S&P
                 shall have in effect a rating for Index Debt, Borrower and the
                 Facility B Lenders will negotiate in good faith to agree upon
                 another rating agency to be substituted by an agreement for
                 the rating agency which shall not have a rating in effect, and
                 in the absence of such agreement the Applicable Margin will be
                 determined by reference to the available rating; (iii) if the
                 ratings established by Moody's and S&P shall differ by one
                 Category, the Applicable Margin shall be determined by
                 reference to the numerically lower Category: (for example, if
                 the rating from S&P is in Category 1 and the rating from
                 Moody's is in Category 2, the Applicable Margin shall be
                 determined by reference to Category 1); (iv) if the ratings
                 established by Moody's and S&P shall differ by more than one
                 Category, the Applicable Margin shall be determined by
                 reference to the Category that is one numerical Category lower
                 than the numerically higher of the two Categories
                 corresponding to the ratings established by the two rating
                 agencies: (for example, if the rating from S&P is in Category
                 2 and the rating from Moody's is in Category 5, the Applicable
                 Margin shall be determined by reference to Category 4); and
                 (v) if any rating established by Moody's or S&P shall be
                 changed (other than as a result of a change in the rating
                 system of either Moody's or S&P), such change shall be
                 effective as of the date on which such change is first
                 announced by the rating agency making such change.  If the
                 rating system of either Moody's or S&P shall change prior to
                 the payment in full of the Obligation and the cancellation of
                 all commitments to lend hereunder, Borrower and the Facility B
                 Lenders shall negotiate in good faith to amend the references
                 to specific ratings in this definition to reflect such changed
                 rating system.  If both Moody's and S&P shall cease to be in
                 the business of rating corporate debt obligations, Borrower
                 and the Facility B Lenders shall negotiate in good faith to
                 agree upon a substitute rating agency and to amend the
                 references to specific ratings in this definition to reflect
                 the ratings used by such substitute rating agency.

         (b)     On any date of determination of the Applicable Margin for
                 Eurodollar Rate Borrowings, if the sum of the Facility A
                 Commitment Usage (as defined in the Facility A Agreement), the
                 Facility B Principal Debt, and the 364-Day Principal Debt
                 exceeds 33 1/3% (but less than 66 2/3%) of the Total
                 Commitment, then the Applicable Margin for Eurodollar Rate
                 Borrowings shall be increased by 0.05% (the "UTILIZATION
                 FEE"); provided that, if the Facility A Commitment Usage (as
                 defined in the Facility A Agreement), the Facility B Principal
                 Debt, and the 364-Day Principal Debt equals or exceeds 66 2/3%
                 of the Total Commitment, then such Utilization Fee shall be
                 increased to 0.10%.





                                                            AMENDED AND RESTATED

the acquisition, construction, or operation of network facilities or any other

         BASE RATE means, for any day, the rate per annum equal to the higher
of (a) the Federal Funds Rate for such day plus one-half of one percent (.5%)
and (b) the Prime Rate for such day.  Any change in the Base Rate due to a
change in the Prime Rate or the Federal Funds Rate shall be effective on the
effective date of such change in the Prime Rate or Federal Funds Rate.

         BASE RATE BORROWING means a Borrowing bearing interest at the sum of
the Base Rate plus the Applicable Margin for Base Rate Borrowings.

         BORROWER is defined in the preamble to this Facility B Agreement.

         BORROWING means any amount disbursed (a) by one or more Facility B
Lenders to Borrower under the Facility B Loan Papers, whether such amount
constitutes an original disbursement of funds or the continuation of an amount
outstanding, or (b) by any Facility B Lender in accordance with, and to satisfy
the obligations of any Restricted Company under, any Facility B Loan Paper.

lesser of (a) as to the respective Type of Borrowing (as designated by Borrower
in accordance with this Facility B Agreement), the Base Rate plus the
Applicable Margin for Base Rate Borrowings or the Adjusted Eurodollar Rate plus
the Applicable Margin for Eurodollar Rate Borrowings, as the case may be, and
(b) the Maximum Rate.  Each change in the Base Rate or the Maximum Rate,
subject to the terms of this Facility B Agreement, will become effective,
without notice to Borrower or any other Person, upon the effective date of such
change.

         3.4     Quotation of Rates.  It is hereby acknowledged that a
Responsible Officer or other appropriately designated employee of Borrower may
call Administrative Agent on or before the date on which a Notice of Conversion
is to be delivered by Borrower in order to receive an indication of the rates
then in effect, but such indicated rates shall neither be binding upon
Administrative Agent or Facility B Lenders nor affect the rate of interest
which thereafter is actually in effect when the Notice of Conversion is given.

         3.5     Default Rate.  At the option of Determining Lenders and to the
extent permitted by Law, all past-





                                                            AMENDED AND RESTATED

                                       17

due Principal Debt and accrued interest thereon shall bear interest from
maturity (stated or by acceleration) at the Default Rate until paid, regardless
whether such payment is made before or after entry of a judgment.

         3.6     Interest Recapture.  If the designated rate applicable to any
Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing
shall be limited to the Maximum Rate, but any subsequent reductions in such
designated rate shall not reduce the rate of interest thereon below the Maximum
Rate until the total amount of interest accrued thereon equals the amount of
interest which would have accrued thereon if such designated rate had at all
times been in effect.  In the event that at maturity (stated or by
acceleration), or at final payment of the Facility B Principal Debt, the total
amount of interest paid or accrued is less than the amount of interest which
would have accrued if such designated rates had at all times been in effect,
then, at such time and to the extent permitted by Law, Borrower shall pay an
amount equal to the difference between (a) the lesser of the amount of interest
which would have accrued if such designated rates had at all times been in
effect and the amount of interest which would have accrued if the Maximum Rate
had at all times been in effect, and (b) the amount of interest actually paid
or accrued on the Facility B Principal Debt.

         3.7     Interest Calculations.

                 (a)      All payments of interest shall be calculated on the
         basis of actual number of days (including the first day but excluding
         the last day) elapsed but computed as if each calendar year consisted
         of 360 days in the case of a Eurodollar Rate Borrowing, or Base Rate
         Borrowings calculated with reference to the Federal Funds Rate (unless
         such calculation would result in the interest on the Borrowings
         exceeding the Maximum Rate in which event such interest shall be
         calculated on the basis of a year of 365 or 366 days, as the case may
         be) and 365 or 366 days, as the case may be, in the case of a Base
         Rate Borrowing calculated with reference to Prime Rate.  All interest
         rate determinations and calculations by Administrative Agent shall be
         conclusive and binding absent manifest error.

                 (b)      The provisions of this Facility B Agreement relating
         to calculation of the Base Rate and the Adjusted Eurodollar Rate, are
         included only for the purpose of determining the rate of interest or
         other amounts to be paid hereunder that are based upon such rate.

         3.8     Maximum Rate.  Regardless of any provision contained in any
Loan Paper, no Lender shall ever be entitled to contract for, charge, take,
reserve, receive, or apply, as interest on the Obligation, or any part thereof,
any amount in excess of the Maximum Rate, and, if Facility B Lenders ever do
so, then such excess shall be deemed a partial prepayment of principal and
treated hereunder as such and any remaining excess shall be refunded to
Borrower.  In determining if the interest paid or payable exceeds the Maximum
Rate, Borrower and Facility B Lenders shall, to the maximum extent permitted
under applicable Law, (a) treat all Borrowings as but a single extension of
credit (and Facility B Lenders and Borrower agree that such is the case and
that provision herein for multiple Borrowings is for convenience only), (b)
characterize any nonprincipal payment as an expense, fee, or premium rather
than as interest, (c) exclude voluntary prepayments and the effects thereof,
and (d) amortize, prorate, allocate, and spread the total amount of interest
throughout the entire contemplated term of the Obligation; provided that, if
the Obligation is paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period
of existence thereof exceeds the Maximum Amount, Facility B Lenders shall
refund such excess, and, in such event, Facility B Lenders shall not, to the
extent permitted by Law, be subject to any penalties provided by any Laws for
contracting for, charging, taking, reserving, or receiving interest in excess
of the Maximum Amount.

         3.9     Interest Periods.  When Borrower requests any Eurodollar Rate
Borrowing, Borrower may elect the interest period (each an "INTEREST PERIOD")
applicable thereto, which shall be, at Borrower's option, one, two, three, or
six months or, if available to all Facility B Lenders, nine or twelve months;
provided, however, that: (a) the initial Interest Period for a Eurodollar Rate
Borrowing shall commence on the date of such Borrowing





                                                            AMENDED AND RESTATED

<PAGE>   24
(including the date of any conversion thereto), and each Interest Period
occurring thereafter in respect of such Borrowing shall commence on the day on
which the next preceding Interest Period applicable thereto expires; (b) if any
Interest Period for a Eurodollar Rate Borrowing begins on a day for which there
is no numerically corresponding Business Day in the calendar month at the end
of such Interest Period, such Interest Period shall end on the next Business
Day immediately following what otherwise would have been such numerically
corresponding day in the calendar month at the end of such Interest Period
(unless such date would be in a different calendar month from what would have
been the month at the end of such Interest Period, or unless there is no
numerically corresponding day in the calendar month at the end of the Interest
Period; whereupon, such Interest Period shall end on the last Business Day in
the calendar month at the end of such Interest Period); (c) no Interest Period
may be chosen with respect to any portion of the Facility B Principal Debt
which would extend beyond the scheduled repayment date (including any dates on
which mandatory prepayments are required to be made) for such portion of the
Principal Debt; and (d) no more than an aggregate of twenty (20) Interest
Periods (including, without limitation, Interest Periods under Facility A)
shall be in effect at one time.

         3.10    Conversions.  Borrower may (a) convert a Eurodollar Rate
Borrowing on the last day of an Interest Period to a Base Rate Borrowing, (b)
convert a Base Rate Borrowing at any time to a Eurodollar Rate Borrowing, and
(c) elect a new Interest Period (in the case of a Eurodollar Rate Borrowing),
by giving notice (a "NOTICE OF CONVERSION," substantially in the form of
EXHIBIT B) of such intent no later than 10:00 a.m. Dallas, Texas time on the
third Business Day prior to the date of conversion or the last day of the
Interest Period, as the case may be (in the case of a conversion to a
Eurodollar Rate Borrowing or an election of a new Interest Period), and no
later than 10:00 a.m. Dallas, Texas time one Business Day prior to the last day
of the Interest Period (in the case of a conversion to a Base Rate Borrowing);
provided that the principal amount converted to, or continued as, a Eurodollar
Rate Borrowing shall be in an amount not less than $10,000,000 or a greater
integral multiple of $1,000,000.  Administrative Agent shall timely notify each
Facility B Lender with respect to each Notice of Conversion.  Absent Borrower's
Notice of Conversion or election of a new Interest Period, a Eurodollar Rate
Borrowing shall be deemed converted to a Base Rate Borrowing effective as of
the expiration of the Interest Period applicable thereto.  No Eurodollar Rate
Borrowing may be either made or continued as a Eurodollar Rate Borrowing, and
no Base Rate Borrowing may be converted to a Eurodollar Rate Borrowing, if the
interest rate for such Eurodollar Rate Borrowing would exceed the Maximum Rate.

         3.11    Order of Application.

                 (a)      So long as no Default or Potential Default has
         occurred and is continuing, payments and prepayments of the Obligation
         shall be applied in the order and manner as Borrower may direct;
         provided that, each such payment or prepayment (other than payments of
         fees payable solely to Administrative Agent, Facility A Administrative
         Agent, or a specific Lender) shall be allocated to each Lender in the
         proportion that the Principal Debt owed to such Lender bears to the
         Principal Debt owed to all Lenders under the Facility (or Subfacility
         thereunder) in respect of which such payment was made.

                 (b)      If a Default or Potential Default has occurred and is
         continuing (or if Borrower fails to give directions as permitted under
         SECTION 3.11(A)), any payment or prepayment (including proceeds from
         the exercise of any Rights) shall be applied in the following order:

                          (i)     to the ratable payment of all fees and
                 reasonable expenses for which Facility A Agents, Facility B
                 Agents, or Lenders have not been paid or reimbursed in
                 accordance with the Loan Papers; (as used in this SECTION
                 3.11(B)(I), a "ratable payment" for any Lender, any Facility A
                 Agent, or any Facility B Agent shall be, on any date of
                 determination, that proportion which the portion of the total
                 fees and indemnities owed to such Lender, Facility A Agent, or
                 Facility B Agent bears to the total aggregate fees and
                 indemnities owed to all Lenders, Facility A Agents, and
                 Facility B Agents on such date of determination);

                          (ii)    to the Pro Rata payment of all accrued and
                 unpaid interest on the Principal Debt;

                          (iii)   to the ratable payment of the Swing Line
                 Principal Debt (as defined in the Facility A Agreement) which
                 is due and payable and which remains unfunded by any Borrowing
                 under Facility A; provided that, such payments shall be
                 allocated among the Swing Line Lenders (as defined in the
                 Facility A Agreement) and the Facility A Lenders which have
                 funded their participation in the Swing Line Principal Debt
                 (as defined in the Facility A Agreement);

                          (iv)    to the ratable payment of any reimbursement
                 obligation with respect to any LC issued pursuant to Facility
                 A which is due and payable and which remains unfunded by any
                 Borrowing under Facility A; provided that, such payments shall
                 be allocated ratably among NationsBank and the Facility A
                 Lenders which have funded their participation in such LC;

                          (v)     to the Pro Rata payment of the remaining
                 Principal Debt in such order as Determining Lenders may elect
                 (provided that, Determining Lenders will apply such proceeds
                 in an order that will minimize any Consequential Loss);

                          (vi)    as a deposit with Administrative Agent, for
                 the benefit of Facility A Lenders, as security for, and to
                 provide for the payment of, any reimbursement obligations, if
                 any, thereafter arising with respect to any issued and
                 outstanding LCs issued pursuant to Facility A; and

                          (vii)   to the payment of the remaining Obligation in
                 the order and manner Determining Lenders deem appropriate.

Subject to the provisions of SECTION 10 and provided that Administrative Agent
shall in any event not be bound to inquire into or to determine the validity,
scope, or priority of any interest or entitlement of any Lender and may suspend
all payments or seek appropriate relief (including, without limitation,
instructions from Determining Lenders or an action in the nature of
interpleader) in the event of any doubt or dispute as to any apportionment or
distribution contemplated hereby, Administrative Agent shall (i) promptly
distribute such amounts to each Facility B Lender in accordance with the
Facility B Agreement and the related Facility B Loan Papers, and (ii) promptly
distribute all payments allocable to Facility A or the Facility A Lenders to
the Facility A Administrative Agent for distribution in accordance with
Facility A and the related Facility A Loan Papers.

         3.12    Sharing of Payments, Etc.  If any Lender shall obtain any
payment (whether voluntary, involuntary, or otherwise, including, without
limitation, as a result of exercising its Rights under SECTION 3.13) which is
in excess of its ratable share of any such payment, such Lender shall purchase
from the other Lenders such participations as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of them;
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, the purchase shall be
rescinded and the purchase price restored to the extent of such recovery.
Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this section may to the fullest extent permitted by Law,
exercise all of its Rights of payment (including the Right of offset) with
respect to such participation as fully as if such Lender were the direct
creditor of Borrower in the amount of such participation.

         3.13    Offset.  Upon the occurrence and during the continuance of a
Default, each Lender shall be entitled to exercise (for the benefit of all
Lenders in accordance with SECTION 3.12) the Rights of offset and/or banker's
Lien against each and every account and other property, or any interest
therein, which Borrower may now or hereafter have with, or which is now or
hereafter in the possession of, such Lender to the extent of the full

amount of the Obligation owed to such Lender.

         3.14    Booking Borrowings.  To the extent permitted by Law, any
Facility B Lender may make, carry, or transfer its Borrowings at, to, or for
the account of any of its branch offices or the office of any of its
Affiliates; provided that no Affiliate shall be entitled to receive any greater
payment under SECTION 3.15 than the transferor Facility B Lender would have
been entitled to receive with respect to such Borrowings.

         3.15    Increased Cost and Reduced Return.

                 (a)      If, after the date hereof, the adoption of any
         applicable Law or any change in any applicable Law, or any change in
         the interpretation or administration thereof by any Governmental
         Authority, or compliance by any Facility B Lender (or its Applicable
         Lending Office) with any request or directive (whether or not having
         the force of law) of any such Governmental Authority:

                          (i)     shall subject such Facility B Lender (or its
                 Applicable Lending Office) to any Tax with respect to any
                 Eurodollar Rate Borrowing, its Notes, or its obligation to
                 loan Eurodollar Rate Borrowings, or change the basis of
                 taxation of any amounts payable to such Facility B Lender (or
                 its Applicable Lending Office) under the Facility B Loan
                 Papers in respect of any Eurodollar Rate Borrowings (other
                 than with respect to Taxes imposed on the overall net income
                 of such Facility B Lender by any jurisdiction and other than
                 liabilities, interest, and penalties incurred as a result of
                 the gross negligence or wilful misconduct of such Facility B
                 Lender;

                          (ii)    shall impose, modify, or deem applicable any
                 reserve, special deposit, assessment, or similar requirement
                 (other than the Reserve Requirement utilized in the
                 determination of the Adjusted Eurodollar Rate) relating to any
                 extensions of credit or other assets of, or any deposits with
                 or other liabilities or commitments of, such Facility B Lender
                 (or its Applicable Lending Office), including the commitment
                 of such Facility B Lender hereunder; or

                          (iii)   shall impose on such Facility B Lender (or
                 its Applicable Lending Office) or the London interbank market
                 any other condition affecting the Facility B Loan Papers or
                 any of such extensions of credit or liabilities or
                 commitments;

         and the result of any of the foregoing is to increase the actual cost
         to such Facility B Lender (or its Applicable Lending Office) of
         making, converting into, continuing, or maintaining any Eurodollar
         Rate Borrowings or to reduce any sum received or receivable by such
         Facility B Lender (or its Applicable Lending Office) under the
         Facility B Loan Papers with respect to any Eurodollar Rate Borrowing,
         then Borrower shall pay to such Facility B Lender on demand such
         amount or amounts as will compensate such Facility B Lender for such
         increased cost or reduction as provided in SECTION 3.15(C) below.  If
         any Facility B Lender requests compensation by Borrower under this
         SECTION 3.15(A), Borrower may, by notice to such Facility B Lender
         (with a copy to Administrative Agent), suspend the obligation of such
         Facility B Lender to loan or continue Borrowings of the Type with
         respect to which such compensation is requested, or to convert
         Borrowings of any other Type into Borrowings of such Type, until the
         event or condition giving rise to such request ceases to be in effect
         (in which case the provisions of SECTION 3.18 shall be applicable);
         provided, that such suspension shall not affect the Right of such
         Facility B Lender to receive the compensation so requested.

                 (b)      If, after the date hereof, any Facility B Lender
         shall have determined that the adoption of any applicable Law
         regarding capital adequacy or any change therein or in the
         interpretation or





                                                            AMENDED AND RESTATED

         administration thereof by any Governmental Authority charged with the
         interpretation or administration thereof, or any request or directive
         regarding capital adequacy (whether or not having the force of law) of
         any such Governmental Authority has or would have the effect of
         reducing the rate of return by an amount deemed by it to be material
         on the capital of such Facility B Lender or any corporation
         controlling such Facility B Lender as a consequence of such Facility B
         Lender's obligations hereunder to a level below that which such
         Facility B Lender or such corporation could have achieved but for such
         adoption, change, request, or directive (taking into consideration its
         policies with respect to capital adequacy), then from time to time
         upon demand Borrower shall pay to such Facility B Lender such
         additional amount or amounts as will compensate such Facility B Lender
         for such reduction.

                 (c)      Each Facility B Lender shall promptly notify Borrower
         and Administrative Agent of any event of which it has knowledge,
         occurring after the date hereof, which will entitle such Facility B
         Lender to compensation pursuant to this Section and will designate a
         different Applicable Lending Office if such designation will avoid the
         need for, or reduce the amount of, such compensation and will not, in
         the reasonable judgment of such Facility B Lender, be otherwise
         disadvantageous to it.  Any Facility B Lender claiming compensation
         under this Section shall furnish to Borrower and Administrative Agent
         a statement setting forth in reasonable detail the additional amount
         or amounts to be paid hereunder which shall be presumed correct in the
         absence of manifest error.  In determining such amount, such Facility
         B Lender may use any reasonable averaging and attribution methods.

         3.16    Limitation on Types of Loans.  If on or prior to the first day
of any Interest Period for any Eurodollar Rate Borrowing:

                 (a)      Administrative Agent determines (which determination
         shall be conclusive absent manifest error) that by reason of
         circumstances affecting the relevant market, adequate and reasonable
         means do not exist for ascertaining the Eurodollar Rate for such
         Interest Period; or

                 (b)      Determining Lenders determine (which determination
         shall be conclusive absent manifest error) and notify Administrative
         Agent that the Adjusted Eurodollar Rate will not adequately and fairly
         reflect the cost to the Facility B Lenders of funding Eurodollar Rate
         Borrowings for such Interest Period;

then Administrative Agent shall give Borrower prompt notice thereof specifying
the relevant amounts or periods, and so long as such condition remains in
effect, the Facility B Lenders shall be under no obligation to fund additional
Eurodollar Rate Borrowings, continue Eurodollar Rate Borrowings, or to convert
Base Rate Borrowings into Eurodollar Rate Borrowings, and Borrower shall, on
the last day(s) of the then current Interest Period(s) for the outstanding
Eurodollar Rate Borrowings, either prepay such Borrowings or convert such
Borrowings into Base Rate Borrowings in accordance with the terms of this
Facility B Agreement.

         3.17    Illegality.  Notwithstanding any other provision of this
Facility B Agreement, in the event that it becomes unlawful for any Facility B
Lender or its Applicable Lending Office to make, maintain, or fund Eurodollar
Rate Borrowings hereunder, then such Facility B Lender shall promptly notify
Borrower thereof and such Facility B Lender's obligation to make or continue
Eurodollar Rate Borrowings and to convert other Base Rate Borrowings into
Eurodollar Rate Borrowings shall be suspended until such time as such Facility
B Lender may again make, maintain, and fund Eurodollar Rate Borrowings (in
which case the provisions of SECTION 3.18 shall be applicable); provided that,
such Facility B Lender will use best efforts (consistent with legal and
regulatory restrictions) to change the jurisdiction of its Applicable Lending
Office so as to eliminate any illegality, if such change, in the reasonable
judgment of such Facility B Lender, is not otherwise disadvantageous to such
Facility B Lender.

         3.18    Treatment of Affected Loans.  If the obligation of any
Facility B Lender to fund Eurodollar Rate Borrowings or to continue, or to
convert Base Rate Borrowings into Eurodollar Rate Borrowings, shall be
suspended pursuant to SECTIONS 3.15, 3.16, or 3.17 hereof, such Facility B
Lender's Eurodollar Rate Borrowings shall be automatically converted into Base
Rate Borrowings on the last day(s) of the then current Interest Period(s) for
Eurodollar Rate Borrowings (or, in the case of a conversion required by SECTION
3.17 hereof, on such earlier date as such Facility B Lender may specify to
Borrower with a copy to Administrative Agent) and, unless and until such
Facility B Lender gives notice as provided below that the circumstances
specified in SECTIONS 3.15, 3.16, or 3.17 hereof that gave rise to such
conversion no longer exist:

                 (a)      to the extent that such Facility B Lender's
         Eurodollar Rate Borrowings have been so converted, all payments and
         prepayments of principal that would otherwise be applied to such
         Facility B Lender's Eurodollar Rate Borrowings shall be applied
         instead to its Base Rate Borrowings; and

                 (b)      all Borrowings that would otherwise be made or
         continued by such Facility B Lender as Eurodollar Rate Borrowings
         shall be made or continued instead as Base Rate Borrowings, and all
         Borrowings of such Facility B Lender that would otherwise be converted
         into Eurodollar Rate Borrowings shall be converted instead into (or
         shall remain as) Base Rate Borrowings.

If such Facility B Lender gives notice to Borrower (with a copy to
Administrative Agent) that the circumstances specified in SECTIONS 3.15, 3.16,
or 3.17 hereof that gave rise to the conversion of such Facility B Lender's
Eurodollar Rate Borrowings pursuant to this SECTION 3.18 no longer exist (which
such Facility B Lender agrees to do promptly upon such circumstances ceasing to
exist) at a time when Eurodollar Rate Borrowings made by other Facility B
Lenders are outstanding, such Facility B Lender's Base Rate Borrowings shall be
automatically converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Eurodollar Rate Borrowings, to the extent
necessary so that, after giving effect thereto, all Eurodollar Rate Borrowings
held by the Facility B Lenders and by such Facility B Lender are held Pro Rata
(as to principal amounts, Types, and Interest Periods) in accordance with their
respective Pro Rata Part of the Facility B Principal Debt.

         3.19    Compensation; Replacement of Facility B Lenders.

                 (a)      Upon the request of any Facility B Lender, Borrower
         shall pay to such Facility B Lender such amount or amounts as shall be
         sufficient (in the reasonable opinion of such Facility B Lender) to
         compensate it for any Consequential Loss; provided that, in each case,
         the Person claiming such Consequential Loss has furnished Borrower
         with a reasonably detailed statement of such loss, which statement
         shall be conclusive in the absence of manifest error.

                 (b)      If any Facility B Lender requests compensation under
         SECTION 3.15 or if Borrower is required to pay additional amounts to
         or for the account of any Facility B Lender pursuant to SECTION 3.20
         (collectively, "ADDITIONAL AMOUNTS"), then Borrower may, at its sole
         expense and effort, upon written notice to such Facility B Lender and
         Administrative Agent, require such Facility B Lender to assign and
         delegate, without recourse, all its interests, Rights, and obligations
         under this Facility B Agreement and the other Facility B Loan Papers
         to an Eligible Assignee that shall assume such obligations; provided
         that, (i) Borrower shall have received the prior written consent of
         Administrative Agent to any such assignment; (ii) such Facility B
         Lender shall have received payment from Borrower of any Additional
         Amounts owed to such Facility B Lender by Borrower for periods prior
         to the replacement of such Facility B Lender and any actual costs
         incurred as a result of such replacement of a Facility B Lender; (iii)
         such assignment will result in reduction or elimination of the
         Additional Amounts; and (iv) such assignment and acceptance shall be
         made in accordance with, and subject to the requirements and
         restrictions contained in, SECTION 11.13(B).  A Facility B Lender
         shall not be required to make any such assignment and delegation if,
         prior thereto, as a result of a waiver by such Facility B Lender or
         otherwise, the





                                                            AMENDED AND RESTATED

         circumstances entitling such Borrowing to require such assignment and
         delegation cease to apply.

         3.20    Taxes.

                 (a)      Any and all payments by Borrower to or for the
         account of any Facility B Lender or Administrative Agent hereunder or
         under any other Loan Paper shall be made free and clear of and without
         deduction for any and all present or future Taxes, excluding, in the
         case of each Facility B Lender and Administrative Agent, Taxes imposed
         on its income and franchise Taxes imposed on it by any jurisdiction
         and other liabilities, interest and penalties incurred as a result of
         the gross negligence or wilful misconduct of such Facility B Lender or
         Administrative Agent (all such Non-Excluded Taxes referred to as
         "NON-EXCLUDED TAXES").  If Borrower shall be required by law to deduct
         any Non-Excluded Taxes from or in respect of any sum payable under
         this Facility B Agreement or any other Facility B Loan Paper to any
         Facility B Lender or Administrative Agent, (i) the sum payable shall
         be increased as necessary so that after making all required deductions
         (including deductions applicable to additional sums payable under this
         SECTION 3.20) such Facility B Lender or Administrative Agent receives
         an amount equal to the sum it would have received had no such
         deductions been made, (ii) Borrower shall make such deductions, (iii)
         Borrower shall pay the full amount deducted to the relevant taxation
         authority or other authority in accordance with applicable law, and
         (iv) Borrower shall furnish to Administrative Agent, at its address
         listed in SCHEDULE 2.1, the original or a certified copy of a receipt
         evidencing payment thereof.

                 (b)      In addition, Borrower agrees to pay any and all
         present or future stamp or documentary taxes and any other excise or
         property Taxes which arise from any payment made under this Facility B
         Agreement or any other Facility B Loan Paper or from the execution or
         delivery of, or otherwise with respect to, this Facility B Agreement
         or any other Facility B Loan Paper (hereinafter referred to as "OTHER
         TAXES").

                 (c)      BORROWER AGREES TO INDEMNIFY EACH FACILITY B LENDER
         AND ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF NON-EXCLUDED TAXES
         THAT SHOULD HAVE BEEN WITHHELD BY BORROWER AND OTHER TAXES (INCLUDING,
         WITHOUT LIMITATION, ANY NON-EXCLUDED TAXES THAT SHOULD HAVE BEEN
         WITHHELD BY BORROWER OR OTHER TAXES IMPOSED OR ASSERTED BY ANY
         JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 3.20) PAID BY SUCH
         FACILITY B LENDER OR ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY
         LIABILITY (INCLUDING PENALTIES, INTEREST, AND EXPENSES OTHER THAN
         THOSE INCURRED AS A RESULT OF THE GROSS NEGLIGENCE OR WILFUL
         MISCONDUCT OF SUCH FACILITY B LENDER OR ADMINISTRATIVE AGENT) ARISING
         THEREFROM OR WITH RESPECT THERETO.

                 (d)      Each Facility B Lender organized under the Laws of a
         jurisdiction outside the United States, on or prior to the date of its
         execution and delivery of this Facility B Agreement in the case of
         each Facility B Lender listed on the signature pages hereof and on or
         prior to the date on which it becomes a Facility B Lender in the case
         of each other Facility B Lender, and from time to time thereafter,
         including, without limitation, upon the expiration or obsolescence of
         any previously delivered form or upon the written request of Borrower
         or Administrative Agent (but only so long as such Facility B Lender
         remains lawfully able to do so), shall provide Borrower and
         Administrative Agent with (i) Internal Revenue Service Form 1001 or
         4224, as appropriate, or any successor form prescribed by the Internal
         Revenue Service, certifying that such Facility B Lender is entitled to
         benefits under an income tax treaty to which the United States is a
         party which reduces the rate of withholding tax on payments of
         interest or certifying that the income receivable pursuant to this
         Facility B Agreement is effectively connected with the conduct of a
         trade or business in the United States, (ii) Internal Revenue Service
         Form W-8 or W-9, as appropriate, or any successor form prescribed by
         the Internal Revenue Service, and (iii) any other form or certificate
         required by any taxing authority (including any certificate required
         by Sections 871(h) and 881(c) of the Internal Revenue Code),
         certifying that such Facility B Lender is entitled to an exemption
         from or a reduced rate of tax on payments pursuant to this Facility B
         Agreement or any of the other Facility B Loan Papers.

                 (e)      For any period with respect to which a Facility B
         Lender has failed to provide Borrower and Administrative Agent with
         the appropriate form pursuant to SECTION 3.20(D) (unless such failure
         is due to a change in Law, occurring subsequent to the date on which a
         form originally was required to be provided), such Facility B Lender
         shall not be entitled to indemnification under this SECTION 3.20 with
         respect to Taxes imposed by the United States; provided, however, that
         should a Facility B Lender, which is otherwise exempt from or subject
         to a reduced rate of withholding tax, become subject to Taxes because
         of its failure to deliver a form required hereunder, Borrower shall
         take such steps as such Facility B Lender shall reasonably request to
         assist such Facility B Lender to recover such Taxes.

                 (f)      If Borrower is required to pay additional amounts to
         or for the account of any Facility B Lender pursuant to this SECTION
         3.20, then such Facility B Lender will use best efforts (consistent
         with legal and regulatory restrictions) to change the jurisdiction of
         its Applicable Lending Office so as to eliminate or reduce any such
         additional payment which may thereafter accrue if such change, in the
         judgment of such Facility B Lender, is not otherwise disadvantageous
         to such Facility B Lender.

                 (g)      Within thirty (30) days after the date of any payment
         of Non-Excluded Taxes or Other Taxes, Borrower shall furnish to
         Administrative Agent the original or a certified copy of a receipt
         evidencing such payment.

                 (h)      Without prejudice to the survival of any other
         agreement of Borrower hereunder, the agreements and obligations of
         Borrower contained in this SECTION 3.20 shall survive the termination
         of this Agreement and the payment in full of the Obligation.

SECTION 4        FEES.

         4.1     Treatment of Fees.  Except as otherwise provided by Law, the
fees described in this SECTION 4: (a) do not constitute compensation for the
use, detention, or forbearance of money, (b) are in addition to, and not in
lieu of, interest and expenses otherwise described in this Facility B
Agreement, (c) shall be payable in accordance with SECTION 3.1, (d) shall be
non-refundable, (e) shall, to the fullest extent permitted by Law, bear
interest, if not paid when due, at the Default Rate, and (f) shall be
calculated on the basis of actual number of days (including the first day, but
excluding the last day) elapsed, but computed as if each calendar year
consisted of 360 days, unless such computation would result in interest being
computed in excess of the Maximum Rate in which event such computation shall be
made on the basis of a year of 365 or 366 days, as the case may be.

         4.2     Fees of Administrative Agent and Arranger.  Borrower shall pay
to Administrative Agent or Arranger, as the case may be, solely for their
respective accounts, the fees described in that certain separate letter
agreement dated as of June 30, 1998 (as thereafter amended or modified from
time to time), among Borrower, Administrative Agent, and Arranger, which
payments shall be made on the dates specified, and in amounts calculated in
accordance with, such letter agreement.

SECTION 5        CONDITIONS PRECEDENT TO CLOSING.  This Facility B Agreement
shall not become effective unless and until (a) Administrative Agent has
received all of the agreements, documents, instruments, and other items
described on SCHEDULE 5, (b) there has been no change in the consolidated
financial condition of the Consolidated Companies from that shown in the
respective Current Financials of such companies which could be a Material
Adverse Event; and (c) Determining Lenders have indicated their consent to this
amendment and restatement of the Existing Agreement by execution and delivery
of a counterpart signature page to this Facility B Agreement; upon satisfaction
of such conditions of closing, the Facility B Loan Papers shall be deemed
effective and binding upon Borrower, Facility B Agents, and all Facility B
Lenders, whether or not such Facility B Lender (other than Determining Lenders)
has executed this Facility B Agreement.  Each condition precedent in this
Facility B Agreement is material to the transactions contemplated in this
Facility B Agreement, and time is of the essence in

respect of each thereof.

SECTION 6        REPRESENTATIONS AND WARRANTIES.  Borrower represents and
warrants to Administrative Agent and Facility B Lenders as follows:

         6.1     Purpose of Credit Facility.  Borrower will use all proceeds of
Borrowings for general corporate purposes of the Restricted Companies,
including, without limitation, liquidity support for commercial paper.  No
Restricted Company is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of purchasing
or carrying any "margin stock" within the meaning of Regulation U.  No part of
the proceeds of any Borrowing will be used, directly or indirectly, for a
purpose which violates any Law, including, without limitation, the provisions
of Regulations T, U, or X (as enacted by the Board of Governors of the Federal
Reserve System, as amended).  "Margin Stock" (as defined in Regulation U)
constitutes less than 25% of those assets of the Restricted Companies which are
subject to any limitation on sale, pledge, or other similar restrictions
hereunder.

         6.2     Existence, Good Standing, Authority, and Authorizations.  Each
Restricted Company is duly organized, validly existing, and in good standing
under the Laws of its jurisdiction of organization.  Except where failure could
not be a Material Adverse Event, each Restricted Company (a) is duly qualified
to transact business and is in good standing in each jurisdiction where the
nature and extent of its business and properties require the same, and (b)
possesses all requisite authority, power, licenses, approvals, permits,
Authorizations, and franchises to use its assets and conduct its business as is
now being, or is contemplated herein to be, conducted, except where failure
could not be a Material Adverse Event.  No Authorization is required to
authorize, or is required in connection with, the execution, delivery,
legality, validity, binding effect, performance, or enforceability of the Loan
Papers (including any change of control occurring as a result thereof)
consummated on or prior to the date this representation or warranty (or
reconfirmation thereof) is made under the Loan Papers, except those
Authorizations the failure of which to be obtained or made could not be a
Material Adverse Event.  The Restricted Companies have obtained all
Authorizations of the FCC and any applicable PUC necessary to conduct their
businesses, and all such Authorizations are in full force and effect, without
conditions, except such conditions as are generally applicable to holders of
such Authorizations.  There are no violations of any such Authorizations which
could, individually or collectively, be a Material Adverse Event, nor are there
any proceedings pending or, to the knowledge of Borrower, threatened against
the Restricted Companies to revoke or limit any such Authorization which could,
individually or collectively, be a Material Adverse Event, and Borrower has no
knowledge that any such Authorizations will not be renewed in the ordinary
course, except for any nonrenewals that could not be a Material Adverse Event.

         6.3     Authorization and Contravention.  The execution, delivery, and
performance by Borrower of each Loan Paper and its obligations thereunder (a)
are within the corporate power of Borrower, (b) will have been duly authorized
by all necessary corporate action on the part of Borrower when such Loan Paper
is executed and delivered, (c) require no action by or in respect of, consent
of, or filing with, any Governmental Authority, which action, consent, or
filing has not been taken or made on or prior to the Closing Date, (d) will not
violate any provision of the charter or bylaws of Borrower, (e) will not
violate any provision of Law applicable to it, other than such violations which
individually or collectively could not be a Material Adverse Event, (f) will
not violate any material written or oral agreements, contracts, commitments, or
understandings to which it is a party, other than such violations which could
not be a Material Adverse Event, or (g) will not result in the creation or
imposition of any Lien on any asset of any Consolidated Company that is
material in relation to the Consolidated Companies taken as a whole.  On and as
of the MCI Merger Date, no action by, or in respect of, consent of, or filing
with, any Governmental Authority or other Person is required in connection with
the MCI Merger which has not been obtained or performed on or prior to the MCI
Merger Date or the failure of which to be obtained or performed would not be a
Material Adverse Event.





                                                            AMENDED AND RESTATED
                                                  FACILITY B TERM LOAN AGREEMENT

<PAGE>   32
         6.4     Binding Effect.  Upon execution and delivery by all parties
thereto, each Loan Paper will constitute a legal, valid, and binding obligation
of Borrower, enforceable against Borrower in accordance with its terms, except
as enforceability may be limited by applicable Debtor Relief Laws and general
principles of equity.

         6.5     Financial Statements.  The Current Financials were prepared in
accordance with GAAP and present fairly, in all material respects, the
consolidated financial condition, results of operations, and cash flows of the
Consolidated Companies as of and for the portion of the fiscal year ending on
the date or dates thereof (subject only to normal year-end audit adjustments).
There were no material liabilities, direct or indirect, fixed or contingent, of
the Consolidated Companies as of the date or dates of the Current Financials
which are required under GAAP to be reflected therein or in the notes thereto,
and are not so reflected.

         6.6     Litigation, Claims, Investigations.  No Restricted Company is
subject to, or aware of the threat of, any Litigation which is reasonably
likely to be determined adversely to any Restricted Company, and, if so
adversely determined, could (individually or collectively with other
Litigation) be a Material Adverse Event. There are no judgments, decrees, or
orders of any Governmental Authority outstanding against any Restricted Company
that could be a Material Adverse Event.

         6.7     Taxes.  All Tax returns of each Consolidated Company required
to be filed have been filed (or extensions have been granted) prior to
delinquency, except for any such returns for which the failure to so file could
not be a Material Adverse Event, and all Taxes imposed upon each Consolidated
Company which are due and payable have been paid prior to delinquency, other
than Taxes for which the criteria for Liens permitted under SECTION 7.13(F)
have been satisfied or for which nonpayment thereof could not constitute a
Material Adverse Event.

         6.8     Environmental Matters. No Consolidated Company (a) knows of
any environmental condition or circumstance, such as the presence or Release of
any Hazardous Substance, on any property presently or previously owned by any
Consolidated Company that could be a Material Adverse Event, (b) knows of any
violation by any Consolidated Company of any Environmental Law, except for such
violations that could not be a Material Adverse Event, or (c) knows that any
Consolidated Company is under any obligation to remedy any violation of any
Environmental Law, except for such obligations that could not be a Material
Adverse Event; provided, however, that each Consolidated Company (x) to the
best of its knowledge, has in full force and effect all environmental permits,
licenses, and approvals required to conduct its operations and is operating in
substantial compliance thereunder, and (y) has taken prudent steps to determine
that its properties and operations are not in violation of any Environmental
Law.

         6.9     ERISA Compliance.  (a) No Employee Plan has incurred an
accumulated funding deficiency, as defined in section 302 of ERISA and section
412 of the Code, (b) neither Borrower nor any ERISA Affiliate has incurred
material liability which is currently due and remains unpaid under Title IV of
ERISA to the PBGC or to an Employee Plan in connection with any such Employee
Plan, (c) neither Borrower nor any ERISA Affiliate has withdrawn in whole or in
part from participation in a Multiemployer Plan, (d) Borrower has not engaged
in any "prohibited transaction" (as defined in section 406 of ERISA or section
4975 of the Code) which would be a Material Adverse Event, and (e) no
Reportable Event has occurred which is likely to result in the termination of
an Employee Plan.  The present value of all benefit liabilities within the
meaning of Title IV of ERISA under each Employee Plan (based on those actuarial
assumptions used to fund such Employee Plan) did not, as of the last annual
valuation date for the 1997 plan year of such Plan, exceed the value of the
assets of such Employee Plan, and the total present values of all benefit
liabilities within the meaning of Title IV of ERISA of all Employee Plans
(based on the actuarial assumptions used to fund each such Plan) did not, as of
the respective annual valuation dates for the 1997 plan year of each such Plan,
exceed the value of the assets of all such plans.

<PAGE>   33
         6.10    Properties; Liens.  Each Restricted Company has good and
marketable title to (or, in the case of Rights of Way, the right to use) all
its property reflected on the Current Financials, except for (a) property that
is obsolete, (b) property that has been disposed of in the ordinary course of
business, (c) property with title defects or failures in title which would not
be a Material Adverse Event, or (d) as otherwise permitted by the Loan Papers.
Except for Liens permitted in SECTION 7.13, there is no Lien on any property of
any Restricted Company, and the execution, delivery, performance, or observance
of the Loan Papers will not require or result in the creation of any Lien on
such property.

         6.11    Government Regulations.  No Restricted Company is subject to
regulation under the Investment Company Act of 1940, as amended, the Public
Utility Holding Company Act of 1935, as amended, or any other Law (other than
Regulations T, U, and X of the Board of Governors of the Federal Reserve System
and the requirements of any PUC or public service commission) which regulates
the incurrence of Debt.

         6.12    No Default.  No event has occurred and is continuing or would
result from the incurring of obligations by Borrower under this Facility B
Agreement or any other Loan Paper which constitutes a Default or a Potential
Default.  No Restricted Subsidiary is in default under or with respect to any
material written or oral agreements, contracts, commitments, or understandings
to which any Restricted Company is party (including without limitation, the
Existing Agreement) which could, individually or together with all such
defaults, be a Material Adverse Event.

         6.13    Senior Indebtedness. All of the Obligation constitutes "senior
indebtedness" or "senior debt" (or ranks at least pari passu with other senior
and unsubordinated indebtedness) under the terms of the Indentures to which

consolidated assets of the Restricted Companies determined as of the date of,
and with respect to, the Current Financials and the related Compliance
Certificate.

         7.20    Mergers and Dissolutions; Sale of Capital Stock. No Restricted
Company will, directly or indirectly, merge or consolidate with any other
Person, other than (a) mergers or consolidations by Borrower with another

Person, if a Restricted Subsidiary is the surviving or resulting entity; (c)
mergers or consolidations among Restricted Companies; (d) as previously

consolidation involving a wholly-owned Restricted Subsidiary, a wholly-owned
Subsidiary must be the surviving or resulting entity; and, (iii) in any merger
or consolidation involving any other Restricted Company (including any

surviving or resulting entity.  No Restricted Company shall liquidate, wind up,
or dissolve (or suffer any liquidation or dissolution), other than (x)
liquidations, wind ups, or dissolutions incident to mergers or consolidations
permitted under this SECTION 7.20, or (y) liquidations, wind ups, or
dissolutions of a Restricted Subsidiary if no Default or Potential Default
exists or would result therefrom and its proportionate share of assets (if any)
are transferred to a Restricted Company.

         7.21    Designation of Unrestricted Companies.  So long as no Default
or Potential Default exists or arises as a result thereof, Borrower may from
time to time designate a Subsidiary as an Unrestricted Subsidiary, or designate
an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, Borrower
shall (a) provide Administrative Agent written notification of such
designation, and (b) deliver to Administrative Agent a Compliance Certificate

prior to and after giving effect to such designation.

         7.22    Financial Covenant.  As calculated on a consolidated basis for

Administrative Agent in the event Borrower discovers or determines that any
computer application that is material to its or any of its Subsidiaries'
business and operations will not be Year 2000 compliant on a timely basis,
except to the extent that such failure is not reasonably expected to be a
Material Adverse Event.

MCI Merger Date, Borrower shall provide Administrative Agent with written
confirmation that all such Debt repayments and commitment terminations have
been effected in connection with the MCI Revolving Facility.

the equivalent thereof in another currency or currencies) to become due and
payable by any Restricted Company (whether by acceleration or by its terms); or
(b) any default exists under any material written or oral agreement, contract,

Company in good faith by appropriate proceedings, and adequate reserves in
respect thereof have been established on the books of such Restricted Company
to the extent required by GAAP.

         8.8     Employee Benefit Plans.  (a) A Reportable Event or Reportable
Events, or a failure to make a required installment or other payment (within

         8.10    Validity and Enforceability of Loan Papers.  Any Loan Paper
shall, at any time after its





                                                            AMENDED AND RESTATED

SECTION 9        RIGHTS AND REMEDIES.

         9.1     Remedies Upon Default.

                 (a)      If a Default exists under SECTION 8.3(C) or 8.3(D),
         the commitment to extend credit hereunder shall automatically
         terminate and the entire unpaid balance of the Obligation under
         Facility B shall automatically become due and payable without any
         action or notice of any kind whatsoever.

                 (b)      If any Default exists, Administrative Agent may (and,
         subject to the terms of SECTION 10, shall upon the request of
         Determining Lenders) or Determining Lenders may, do any one or more of
         the following: (i) if the maturity of the Obligation under Facility B
         has not already been accelerated under SECTION 9.1(A), declare the
         entire unpaid balance of the Obligation under Facility B, or any part
         thereof, immediately due and payable, whereupon it shall be due and
         payable; (ii) terminate the commitments of Lenders to extend credit
         hereunder; (iii) reduce any claim to judgment; (iv) to the extent
         permitted by Law, exercise (or request each Facility B Lender to, and
         each Facility B Lender shall be entitled to, exercise) the Rights of
         offset or banker's Lien against the interest of Borrower in and to
         every account and other property of Borrower which are in the
         possession of Administrative Agent or any Facility B Lender to the
         extent of the full amount of the Obligation (to the extent permitted
         by Law, Borrower being deemed directly obligated to each Lender in the
         full amount of the Obligation for such purposes); and (v) exercise any
         and all other legal or equitable Rights afforded by the Loan Papers,
         the Laws of the State of New York, or any other applicable
         jurisdiction as Administrative Agent shall deem appropriate, or
         otherwise, including, but not limited to, the Right to bring suit or
         other proceedings before any Governmental Authority either for
         specific performance of any covenant or condition contained in any of
         the Loan Papers or in aid of the exercise of any Right granted to
         Administrative Agent or any Facility B Lender in any of the Loan
         Papers.

         9.2     Company Waivers.  To the extent permitted by Law, Borrower
hereby waives presentment and demand for payment, protest, notice of intention
to accelerate, notice of acceleration, and notice of protest and nonpayment,
and agrees that its liability with respect to the Obligation (or any part
thereof), shall not be affected by any renewal or extension in the time of
payment of the Obligation (or any part thereof), by any indulgence, or by any
release or change in any security for the payment of the Obligation (or any
part thereof).

         9.3     Performance by Administrative Agent.  If any covenant, duty,
or agreement of any Consolidated Company is not performed in accordance with
the terms of the Loan Papers, after the occurrence and during the continuance
of a Default, Administrative Agent may, at its option (but subject to the
approval of Determining Lenders), perform or attempt to perform such covenant,
duty, or agreement on behalf of such Consolidated Company.  In such event, any
amount expended by Administrative Agent in such performance or attempted
performance shall be payable by the Consolidated Companies, jointly and
severally, to Administrative Agent on demand, shall become part of the
Obligation, and shall bear interest at the Default Rate from the date of such
expenditure by Administrative Agent until paid.  Notwithstanding the foregoing,
it is expressly understood that Administrative Agent does not assume and shall
never have, except by its express written consent, any liability or
responsibility for the performance of any covenant, duty, or agreement of any
Consolidated Company.

         9.4     Delegation of Duties and Rights.  Facility B Lenders may
perform any of their duties or exercise any of their Rights under the Loan
Papers by or through their respective Representatives.





                                                            AMENDED AND RESTATED

                                       37
<PAGE>   43
         9.5     Not in Control.  Nothing in any Loan Paper shall, or shall be
deemed to (a) give Administrative Agent, any Agent, or any Facility B Lender
the Right to exercise control over the assets (including real property),
affairs, or management of any Consolidated Company, (b) preclude or interfere
with compliance by any Consolidated Company with any Law, or (c) require any
act or omission by any Consolidated Company that may be harmful to Persons or
property.  Any "Material Adverse Event" or other materiality qualifier in any
representation, warranty, covenant, or other provision of any Loan Paper is
included for credit documentation purposes only and shall not, and shall not be
deemed to, mean that Administrative Agent, any Agent, or any Facility B Lender
acquiesces in any non-compliance by any Consolidated Company with any Law or
document, or that Administrative Agent, any Agent, or any Facility B Lender
does not expect the Consolidated Companies to promptly, diligently, and
continuously carry out all appropriate removal, remediation, and termination
activities required or appropriate in accordance with all Environmental Laws.
Neither the Administrative Agent nor any Facility B Lender has any fiduciary
relationship with or fiduciary duty to Borrower or any Consolidated Company
arising out of or in connection with the Loan Papers, and the relationship
between the Administrative Agent and Facility B Lenders, on the one hand, and
Borrower, on the other hand, in connection with the Loan Papers is solely that
of debtor and creditor. The power of Facility B Agents and Lenders under the
Loan Papers is limited to the Rights provided in the Loan Papers, which Rights
exist solely to assure payment and performance of the Obligation and may be
exercised in a manner calculated by Facility B Agents and Lenders in their
respective good faith business judgment.

         9.6     Course of Dealing.  The acceptance by Administrative Agent or
Lenders at any time and from time to time of partial payment on the Obligation
shall not be deemed to be a waiver of any Default then existing.  No waiver by
Administrative Agent, Determining Lenders, or Lenders of any Default shall be
deemed to be a waiver of any other then- existing or subsequent Default.  No
delay or omission by Administrative Agent, Determining Lenders, or Lenders in
exercising any Right under the Loan Papers shall impair such Right or be
construed as a waiver thereof or any acquiescence therein, nor shall any single
or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

         9.7     Cumulative Rights.  All Rights available to Administrative
Agent and Lenders under the Loan Papers are cumulative of and in addition to
all other Rights granted to Administrative Agent and Lenders at law or in
equity, whether or not the Obligation is due and payable and whether or not
Administrative Agent or Lenders have instituted any suit for collection,
foreclosure, or other action in connection with the Loan Papers.

         9.8     Application of Proceeds.  Any and all proceeds ever received
by Administrative Agent or Lenders from the exercise of any Rights pertaining
to the Obligation shall be applied to the Obligation in the order and manner
set forth in SECTION 3.11.

         9.9     Certain Proceedings.  Borrower will promptly execute and
deliver, or cause the execution and delivery of, all applications,
certificates, instruments, registration statements, and all other documents and
papers Administrative Agent or Facility B Lenders may reasonably request in
connection with the obtaining of any consent, approval, registration,
qualification, permit, license, or authorization of any Governmental Authority
or other Person necessary or appropriate for the effective exercise of any
Rights under the Loan Papers.  Because Borrower agrees that Administrative
Agent's and Facility B Lenders' remedies at Law for failure of Borrower to
comply with the provisions of this paragraph would be inadequate and that such
failure would not be adequately compensable in damages, Borrower agrees that
the covenants of this paragraph may be specifically enforced.

         9.10    Limitation of Rights.  Notwithstanding any other provision of
this Facility B Agreement or any other Loan Paper, any action taken or proposed
to be taken by Administrative Agent or any other Facility B Agent or any Lender
under any Loan Paper which would affect the operational, voting, or other
control of any Consolidated Company, shall be pursuant to Section 310(d) of the
Communications Act of 1934 (as amended), any applicable state Law, and the
applicable rules and regulations thereunder and, if and to the extent required
thereby, subject to





                                                            AMENDED AND RESTATED

the prior consent of the FCC or any applicable PUC.

         9.11    Expenditures by Lenders.  Borrower shall promptly pay within
fifteen (15) Business Days after request therefor (a) all reasonable costs,
fees, and expenses paid or incurred by Administrative Agent incident to any
Loan Paper (including, but not limited to, the reasonable fees and expenses of
counsel to Administrative Agent and the allocated cost of internal counsel in
connection with the negotiation, preparation, delivery, execution, coordination
and administration of the Loan Papers and any related amendment, waiver, or
consent) and (b) all reasonable costs and expenses of Facility B Lenders, and
Administrative Agent incurred by Administrative Agent, or any Facility B Lender
in connection with the enforcement of the obligations of any Restricted Company
arising under the Loan Papers (including, without limitation, costs and
expenses incurred in connection with any workout or bankruptcy) or the exercise
of any Rights arising under the Loan Papers (including, but not limited to,
reasonable attorneys' fees including allocated cost of internal counsel, court
costs and other costs of collection), all of which shall be a part of the
Obligation and shall bear interest at the Default Rate from the date due until
the date repaid by Borrower.

         9.12    INDEMNIFICATION.  BORROWER, FOR ITSELF AND ON BEHALF OF THE
OTHER RESTRICTED COMPANIES, INDEMNIFIES, PROTECTS, AND HOLDS ADMINISTRATIVE
AGENT, EACH OTHER FACILITY B AGENT, AND EACH LENDER AND THEIR RESPECTIVE
AFFILIATES, PARENTS, AND SUBSIDIARIES, AND EACH OF THE FOREGOING PARTIES'
RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES, AGENTS, SUCCESSORS,
ASSIGNS, AND ATTORNEYS (COLLECTIVELY, THE "INDEMNIFIED PARTIES") HARMLESS FROM
AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, CLAIMS, AND PROCEEDINGS AND ALL REASONABLE AND
NECESSARY COSTS, EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL REASONABLE
ATTORNEYS' FEES AND LEGAL EXPENSES INCLUDING ALLOCATED COST OF INTERNAL
COUNSEL, AND AMOUNTS PAID IN SETTLEMENT WHETHER OR NOT SUIT IS BROUGHT), AND
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER, AND AMOUNTS PAID IN SETTLEMENT
(THE "INDEMNIFIED LIABILITIES") WHICH MAY AT ANY TIME BE IMPOSED ON, INCURRED
BY, OR ASSERTED AGAINST THE INDEMNIFIED PARTIES, IN ANY WAY RELATING TO OR
ARISING OUT OF (A) THE DIRECT OR INDIRECT RESULT OF THE VIOLATION BY ANY
CONSOLIDATED COMPANY OF ANY ENVIRONMENTAL LAW, AS WELL AS ANY AMENDMENT AND
SUPPLEMENT THERETO AND ANY STATE COUNTERPART THEREOF; (B) ANY CONSOLIDATED
COMPANY'S GENERATION, MANUFACTURE, PRODUCTION, STORAGE, TRANSPORTATION,
RELEASE, THREATENED RELEASE, DISCHARGE, DISPOSAL OR PRESENCE IN CONNECTION WITH
ITS PROPERTIES OF A HAZARDOUS SUBSTANCE (INCLUDING, WITHOUT LIMITATION, (I) ALL
DAMAGES ARISING FROM ANY SUCH USE, GENERATION, MANUFACTURE, PRODUCTION,
STORAGE, RELEASE, THREATENED RELEASE, DISCHARGE, DISPOSAL, OR PRESENCE, OR (II)
THE COSTS OF ANY REQUIRED OR NECESSARY ENVIRONMENTAL INVESTIGATION, MONITORING,
REPAIR, CLEANUP, OR DETOXIFICATION AND THE PREPARATION AND IMPLEMENTATION OF
ANY CLOSURE, REMEDIAL, OR OTHER PLANS); OR (C) THE LOAN PAPERS OR ANY OF THE
TRANSACTIONS CONTEMPLATED THEREIN OR THE USE OF PROCEEDS OF ANY BORROWING, TO
THE EXTENT THAT ANY OF THE INDEMNIFIED LIABILITIES RESULTS, DIRECTLY OR
INDIRECTLY, FROM ANY CLAIM MADE OR ACTION, SUIT, OR PROCEEDING COMMENCED BY OR
ON BEHALF OF ANY PERSON OTHER THAN BY THE INDEMNIFIED PARTIES; (PROVIDED THAT,
NONE OF THE RESTRICTED COMPANIES SHALL HAVE ANY OBLIGATION HEREUNDER TO ANY
INDEMNIFIED PARTY WITH RESPECT TO ANY INDEMNIFIED LIABILITY ARISING FROM (I)
THE FRAUD, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY OR
ANY ASSOCIATED PERSON OF SUCH INDEMNIFIED PARTY, OR (II) LEGAL PROCEEDINGS
COMMENCED AGAINST ANY INDEMNIFIED PARTY BY ANY SECURITY HOLDER OR CREDITOR
THEREOF ARISING OUT OF AND BASED UPON RIGHTS AFFORDED TO SUCH PERSON SOLELY IN
SUCH CAPACITY).  AS USED IN THIS PARAGRAPH, THE TERM "ASSOCIATED PERSON" MEANS,
WITH RESPECT TO ANY PERSON, THE AFFILIATES, PARENTS, SUBSIDIARIES, DIRECTORS,
OFFICERS, EMPLOYEES, REPRESENTATIVES, AGENTS, SUCCESSORS, ASSIGNS, AND
ATTORNEYS OF SUCH PERSON, OR OF ANOTHER PERSON OF WHICH SUCH PERSON IS ALSO AN
ASSOCIATED PERSON.  THE PROVISIONS OF AND UNDERTAKINGS AND INDEMNIFICATION SET
FORTH IN THIS PARAGRAPH SHALL SURVIVE THE SATISFACTION AND PAYMENT OF THE
OBLIGATION AND TERMINATION OF THIS FACILITY B AGREEMENT.  AN INDEMNIFIED PARTY
WILL PROMPTLY NOTIFY THE RESTRICTED COMPANIES UPON RECEIPT OF WRITTEN NOTICE OF
ANY CLAIM, ACTION, SUIT, OR PROCEEDING MADE, COMMENCED, OR THREATENED THAT
COULD GIVE RISE TO AN INDEMNIFIED LIABILITY AND AFFORD THE RESTRICTED COMPANIES
FIRST RIGHT TO DEFEND OR RESOLVE THE SAME (WITH COUNSEL REASONABLY SATISFACTORY
TO SUCH INDEMNIFIED PARTY); PROVIDED THAT, ANY FAILURE BY SUCH INDEMNIFIED
PARTY TO GIVE SUCH NOTICE SHALL NOT RELIEVE THE RESTRICTED COMPANIES FROM THEIR
OBLIGATIONS TO INDEMNIFY THE INDEMNIFIED PARTY TO THE EXTENT SUCH FAILURE DOES

SECTION 10       AGREEMENT AMONG LENDERS.

         10.1    Administrative Agent.

                 (a)      Each Facility B Lender (including any Facility B
         Lender in its capacity as an issuer of a Financial Hedge) hereby
         appoints NationsBank (and NationsBank hereby accepts such appointment)
         as its nominee and agent, in its name and on its behalf:  (i) to act
         as nominee for and on behalf of such Facility B Lender in and under
         all Facility B Loan Papers; (ii) to arrange the means whereby the
         funds of Facility B Lenders are to be made available to Borrower under
         the Facility B Loan Papers; (iii) to take such action as may be
         requested by any Facility B Lender under the Facility B Loan Papers
         (when such Facility B Lender is entitled to make such request under
         the Facility B Loan Papers and after such requesting Facility B Lender
         has obtained the concurrence of such other Facility B Lenders as may
         be required under the Facility B Loan Papers); (iv) to receive all
         documents and items to be furnished to Facility B Lenders under the
         Facility B Loan Papers; (v) to be the secured party, mortgagee,
         beneficiary, and similar party in respect of, and to receive, as the
         case may be, any collateral for the benefit of Facility B Lenders;
         (vi) to timely distribute, and Administrative Agent agrees to so
         distribute, to each Facility B Lender all material information,
         requests, documents, and items received from Borrower under the
         Facility B Loan Papers; (vii) to promptly distribute to each Facility
         B Lender its ratable part of each payment or prepayment (whether
         voluntary, as proceeds of collateral upon or after foreclosure, as
         proceeds of insurance thereon, or otherwise) in accordance with the
         terms of the Facility B Loan Papers; (viii) to deliver to the
         appropriate Persons requests, demands, approvals, and consents
         received from Facility B Lenders; and (ix) to execute, on behalf of
         Facility B Lenders, such releases or other documents or instruments as
         are permitted by the Facility B Loan Papers or as directed by Facility
         B Lenders from time to time; provided, however, Administrative Agent
         shall not be required to take any action which exposes Administrative
         Agent to personal liability or which is contrary to the Facility B
         Loan Papers or applicable Law.

                 (b)      Administrative Agent may resign at any time as
         Administrative Agent under the Facility B Loan Papers by giving
         written notice thereof to Facility B Lenders and may be removed as
         Administrative Agent under the Facility B Loan Papers at any time with
         cause by Determining Lenders.  Should the initial or any successor
         Administrative Agent ever cease to be a party hereto or should the
         initial or any successor Administrative Agent ever resign or be
         removed as Administrative Agent, then Determining Lenders shall elect
         the successor Administrative Agent from among the Lenders (other than
         the resigning Administrative Agent).  If no successor Administrative
         Agent shall have been so appointed by Determining Lenders, within 30
         days after the retiring Administrative Agent's giving of notice of
         resignation or Determining Lenders' removal of the retiring
         Administrative Agent, then the retiring Administrative Agent may, on
         behalf of Facility B Lenders, appoint a successor Administrative
         Agent, which shall be a commercial bank having a combined capital and
         surplus of at least $1,000,000,000.  Upon the acceptance of any
         appointment as Administrative Agent under the Facility B Loan Papers
         by a successor Administrative Agent, such successor Administrative
         Agent shall thereupon succeed to and become vested with all the





                                                            AMENDED AND RESTATED
                                                  FACILITY B TERM LOAN AGREEMENT

                                       40
<PAGE>   46
         Rights of the retiring Administrative Agent, and the retiring
         Administrative Agent shall be discharged from its duties and
         obligations of Administrative Agent under the Facility B Loan Papers,
         and each Facility B Lender shall execute such documents as any
         Facility B Lender may reasonably request to reflect such change in and
         under the Facility B Loan Papers.  After any retiring Administrative
         Agent's resignation or removal as Administrative Agent under the
         Facility B Loan Papers, the provisions of this SECTION 10 shall inure
         to its benefit as to any actions taken or omitted to be taken by it
         while it was Administrative Agent under the Facility B Loan Papers.

                 (c)      Administrative Agent, in its capacity as a Facility B
         Lender, shall have the same Rights under the Facility B Loan Papers as
         any other Facility B Lender and may exercise the same as though it
         were not acting as Administrative Agent; the term "Facility B Lender"
         shall, unless the context otherwise indicates, include Administrative
         Agent; and any resignation, or removal of by Administrative Agent
         hereunder shall not impair or otherwise affect any Rights which it has
         or may have in its capacity as an individual Facility B Lender.  Each
         Facility B Lender and Borrower agree that Administrative Agent is not
         a fiduciary for Facility B Lenders or for Borrower but simply is
         acting in the capacity described herein to alleviate administrative
         burdens for both Borrower and Facility B Lenders, that Administrative
         Agent has no duties or responsibilities to Facility B Lenders or
         Borrower except those expressly set forth herein, and that
         Administrative Agent in its capacity as a Facility B Lender has all
         Rights of any other Lender.

                 (d)      Administrative Agent and its Affiliates may now or
         hereafter be engaged in one or more loan, letter of credit, leasing,
         or other financing transactions with Borrower, act as trustee or
         depositary for Borrower, or otherwise be engaged in other transactions
         with Borrower (collectively, the "OTHER ACTIVITIES") not the subject
         of the Facility B Loan Papers.  Without limiting the Rights of
         Facility B Lenders specifically set forth in the Facility B Loan
         Papers, Administrative Agent and its Affiliates shall not be
         responsible to account to Facility B Lenders for such other
         activities, and no Facility B Lender shall have any interest in any
         other activities, any present or future guaranties by or for the
         account of Borrower which are not contemplated or included in the
         Facility B Loan Papers, any present or future offset exercised by
         Administrative Agent and its Affiliates in respect of such other
         activities, any present or future property taken as security for any
         such other activities, or any property now or hereafter in the
         possession or control of Administrative Agent or its Affiliates which
         may be or become security for the obligations of Borrower arising
         under the Facility B Loan Papers by reason of the general description
         of indebtedness secured or of property contained in any other
         agreements, documents or instruments related to any such other
         activities; provided that, if any payments in respect of such
         guaranties or such property or the proceeds thereof shall be applied
         to reduction of the obligations of Borrower arising under the Facility
         B Loan Papers, then each Facility B Lender shall be entitled to share
         in such application ratably.

                 (e)      Each Facility B Lender acknowledges that, and
         consents to, NationsBank's also serving as the Facility A
         Administrative Agent and the "Administrative Agent" under the 364-Day
         Facility.

         10.2    Expenses.  Upon demand by Administrative Agent, each Facility
B Lender shall pay its Pro Rata Part of any reasonable expenses (including,
without limitation, court costs, reasonable attorneys' fees and other costs of
collection) incurred by Administrative Agent in connection with any of the
Facility B Loan Papers if and to the extent Administrative Agent does not
receive reimbursement therefor from other sources within 60 days after
incurred; provided that each Facility B Lender shall be entitled to receive its
Pro Rata Part of any reimbursement for such expenses, or part thereof, which
Administrative Agent subsequently receives from such other sources.

         10.3    Proportionate Absorption of Losses.  Except as otherwise
provided in the Loan Papers, nothing in the Loan Papers shall be deemed to give
any Lender any advantage over any other Lender insofar as the Obligation





                                                            AMENDED AND RESTATED
                                                  FACILITY B TERM LOAN AGREEMENT

                                       41
<PAGE>   47
arising under the Loan Papers is concerned, or to relieve any Lender from
absorbing its Pro Rata Part of any losses sustained with respect to the
Obligation (except to the extent such losses result from unilateral actions or
inactions of any Lender that are not made in accordance with the terms and
provisions of the Loan Papers).

         10.4    Delegation of Duties; Reliance.  Administrative Agent may
perform any of its duties or exercise any of its Rights under the Facility B
Loan Papers by or through its Representatives.  Administrative Agent and its
Representatives shall (a) be entitled to rely upon (and shall be protected in
relying upon) any writing, resolution, notice, consent, certificate, affidavit,
letter, cablegram, telecopy, telegram, telex or teletype message, statement,
order, or other documents or conversation believed by it or them to be genuine
and correct and to have been signed or made by the proper Person and, with
respect to legal matters, upon opinion of counsel selected by Administrative
Agent, (b) be entitled to deem and treat each Facility B Lender as the owner
and holder of the Facility B Principal Debt owed to such Facility B Lender for
all purposes until, subject to SECTION 11.13, written notice of the assignment
or transfer thereof shall have been given to and received by Administrative
Agent (and any request, authorization, consent, or approval of any Facility B
Lender shall be conclusive and binding on each subsequent holder, assignee, or
transferee of the Facility B Principal Debt owed to such Facility B Lender or
portion thereof until such notice is given and received), (c) not be deemed to
have notice of the occurrence of a Default unless a responsible officer of
Administrative Agent, who handles matters associated with the Facility B Loan
Papers and transactions thereunder, has actual knowledge thereof or
Administrative Agent has been notified thereof by a Facility B Lender or
Borrower, and (d) be entitled to consult with legal counsel (including counsel
for Borrower), independent accountants and other experts selected by
Administrative Agent and shall not be liable for any action taken or omitted to
be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts.

         10.5    Limitation of Liability.

                 (a)      None of the Facility B Agents or any of their
         respective Representatives shall be liable for any action taken or
         omitted to be taken by it or them under the Loan Papers in good faith
         and reasonably believed by it or them to be within the discretion or
         power conferred upon it or them by the Loan Papers or be responsible
         for the consequences of any error of judgment, except for fraud, gross
         negligence, or willful misconduct as found in a final, non-appealable
         judgment by a court of competent jurisdiction; and none of the
         Facility B Agents or any of their respective Representatives has a
         fiduciary relationship with any Facility B Lender by virtue of the
         Loan Papers (provided that nothing herein shall negate the obligation
         of Administrative Agent to account for funds received by it for the
         account of any Facility B Lender).

                 (b)      Unless indemnified to its satisfaction against loss,
         cost, liability, and expense, no Facility B Agent shall be compelled
         to do any act under the Loan Papers or to take any action toward the
         execution or enforcement of the powers thereby created or to prosecute
         or defend any suit in respect of the Loan Papers.  If any Facility B
         Agent requests instructions from Facility B Lenders or Determining
         Lenders, as the case may be, with respect to any act or action
         (including, but not limited to, any failure to act) in connection with
         any Facility B Loan Paper, or Loan Paper, such Facility B Agent shall
         be entitled (but shall not be required) to refrain (without incurring
         any liability to any Person by so refraining) from such act or action
         unless and until it has received such instructions.  In no event,
         however, shall any Facility B Agent or any of its respective
         Representatives be required to take any action which it or they
         determine could incur for it or them criminal or onerous civil
         liability.  Without limiting the generality of the foregoing, no
         Facility B Lender shall have any right of action against any Facility
         B Agent as a result of such Agent's acting or refraining from acting
         hereunder in accordance with the instructions of Determining Lenders.

                 (c)      Facility B Agents shall not be responsible in any
         manner to any Facility B Lender or any





                                                            AMENDED AND RESTATED

<PAGE>   48
         Participant for, and each Facility B Lender represents and warrants
         that it has not relied upon Facility B Agents in respect of, (i) the
         creditworthiness of any Restricted Company and the risks involved to
         such Facility B Lender, (ii) the effectiveness, enforceability,
         genuineness, validity, or the due execution of any Loan Paper, (iii)
         any representation, warranty, document, certificate, report, or
         statement made therein or furnished thereunder or in connection
         therewith, (iv) the existence, priority, or perfection of any Lien
         hereafter granted or purported to be granted under any Loan Paper, or
         (v) observation of or compliance with any of the terms, covenants, or
         conditions of any Loan Paper on the part of any Restricted Company.
         Each Facility B Lender agrees to indemnify each Facility B Agent and
         its respective Representatives and hold them harmless from and against
         (but limited to such Lender's Pro Rata Part of) any and all
         liabilities, obligations, losses, damages, penalties, actions,
         judgments, suits, costs, reasonable expenses, and reasonable
         disbursements of any kind or nature whatsoever which may be imposed
         on, asserted against, or incurred by them in any way relating to or
         arising out of the Loan Papers or any action taken or omitted by them
         under the Loan Papers, to the extent any Facility B Agent and its
         respective Representatives are not reimbursed for such amounts by any
         Restricted Company (provided that, no Facility B Agent and its
         respective Representatives shall have the right to be indemnified
         hereunder for its or their own fraud, gross negligence, or willful
         misconduct as found in a final, non-appealable judgment by a court of
         competent jurisdiction).

         10.6    Default; Collateral.  Upon the occurrence and continuance of a
Default, Facility B Lenders agree to promptly confer in order that Determining
Lenders or Facility B Lenders, as the case may be, may agree upon a course of
action for the enforcement of the Rights of Facility B Lenders; and
Administrative Agent shall be entitled to refrain from taking any action
(without incurring any liability to any Person for so refraining) unless and
until Administrative Agent shall have received instructions from Determining
Lenders.  In actions with respect to any property of Borrower, Administrative
Agent is acting for the ratable benefit of each Facility B Lender.  Any and all
agreements to subordinate (whether made heretofore or hereafter) other
indebtedness or obligations of Borrower to the Obligation shall be construed as
being for the ratable benefit of each Facility B Lender.  If Administrative
Agent acquires any security for the Obligation or any guaranty of the
Obligation upon or in lieu of foreclosure, the same shall be held for the
ratable benefit of all Lenders in proportion to the Principal Debt respectively
owed to each Lender.

         10.7    Limitation of Liability.  To the extent permitted by Law, (a)
no Facility B Agent (acting in its respective agent capacities) shall incur any
liability to any other Lender, Facility B Agent, or Participant, except for
acts or omissions resulting from its own fraud, gross negligence or wilful
misconduct as found in a final, non- appealable judgment by a court of
competent jurisdiction, and (b) no Facility B Agent, nor any Lender or
Participant shall incur any liability to any other Person for any act or
omission of any other Lender or any other Participant.

         10.8    Relationship of Lenders.  Nothing herein shall be construed as
creating a partnership or joint venture among Facility B Agents and Facility B
Lenders or among Lenders.

         10.9    Benefits of Agreement.  Except for the representations and
covenants in SECTION 10.1(C) in favor of Borrower, none of the provisions of
this SECTION 10 shall inure to the benefit of any Restricted Company or any
other Person other than Facility B Lenders and Facility B Agents; consequently,
neither any Restricted Company nor any other Person shall be entitled to rely
upon, or to raise as a defense, in any manner whatsoever, the failure of any
Facility B Lender or Facility B Agent to comply with such provisions.

         10.10   Agents.  None of the Facility B Lenders identified in this
Facility B Agreement as a "Co-Syndication Agent" shall have any rights, powers,
obligations, liabilities, responsibilities, or duties under this Facility B
Agreement, other than those applicable to all Facility B Lenders as such.
Without limiting the foregoing, none of the Facility B Lenders so identified as
a "Co-Syndication Agent" shall have or be deemed to have





                                                            AMENDED AND RESTATED

any fiduciary relationship with any Facility B Lender.

SECTION 11       MISCELLANEOUS.

         11.1    Headings.  The headings, captions, and arrangements used in
any of the Loan Papers are, unless specified otherwise, for convenience only
and shall not be deemed to limit, amplify, or modify the terms of the Loan
Papers, nor affect the meaning thereof.

         11.2    Nonbusiness Days.  In any case where any payment or action is
due under any Loan Paper on a day which is not a Business Day, such payment or
action may be delayed until the next-succeeding Business Day, but interest and
fees shall continue to accrue in respect of any payment to which it is
applicable until such payment is in fact made; provided that, if in the case of
any such payment in respect of a Eurodollar Rate Borrowing the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

         11.3    Communications.  Unless specifically otherwise provided,
whenever any Facility B Loan Paper requires or permits any consent, approval,
notice, request, or demand from one party to another, such communication must
be in writing (which may be by telex or telecopy) to be effective and shall be
deemed to have been given (a) if by telex, when transmitted to the telex
number, if any, for such party, and the appropriate answer back is received,
(b) if by telecopy, when transmitted to the telecopy number for such party (and
all such communications sent by telecopy shall be confirmed promptly thereafter
by personal delivery or mailing in accordance with the provisions of this
section; provided, that any requirement in this parenthetical shall not affect
the date on which such telecopy shall be deemed to have been delivered), (c) if
by mail, on the third Business Day after it is enclosed in an envelope,
properly addressed to such party, properly stamped, sealed, and deposited in
the appropriate official postal service, or (d) if by any other means, when
actually delivered to such party.  Until changed by notice pursuant hereto, the
address (and telex and telecopy numbers, if any) for Administrative Agent and
each other Facility B Agent and each Facility B Lender is set forth on SCHEDULE
2.1, and for Borrower and each Restricted Company is the address set forth by
Borrower's signature on the signature page of this Facility B Agreement.  A
copy of each communication to Administrative Agent shall also be sent to Haynes
and Boone, L.L.P., 901 Main Street, Dallas, Texas  75202, Fax: 214/651-5940,
Attn: Karen S. Nelson; a copy of each communication to any Consolidated Company
shall also be sent to WorldCom, Inc., 10777 Sunset Office Drive, St. Louis, MO
63127, Attn: Bruce Borghardt.

         11.4    Form and Number of Documents.  Each agreement, document,
instrument, or other writing to be furnished under any provision of this
Facility B Agreement must be in form and substance and in such number of
counterparts as may be reasonably satisfactory to Administrative Agent and its
counsel.

         11.5    Exceptions to Covenants.  No Restricted Company shall take any
action or fail to take any action which is permitted as an exception to any of
the covenants contained in any Loan Paper if such action or omission would
result in the breach of any other covenant contained in any of the Loan Papers.

         11.6    Survival.  All covenants, agreements, undertakings,
representations, and warranties made in any of the Facility B Loan Papers shall
survive all closings under the Facility B Loan Papers and, except as otherwise
indicated, shall not be affected by any investigation made by any party.  All
rights of, and provisions relating to, reimbursement and indemnification of
Administrative Agent, any Agent, or any Facility B Lender shall survive
termination of this Facility B Agreement and payment in full of the Obligation.

         11.7    Governing Law.  THE FACILITY B LOAN PAPERS HAVE BEEN ENTERED
INTO PURSUANT TO SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW, AND
THE LAWS (OTHER THAN CONFLICT OF LAWS PROVISIONS THEREOF) OF THE STATE OF NEW
YORK AND OF THE UNITED STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF
THE PARTIES TO THE FACILITY B LOAN PAPERS AND THE VALIDITY, CONSTRUCTION,
ENFORCEMENT, AND INTERPRETATION OF THE FACILITY B LOAN PAPERS.

         11.8    Invalid Provisions.  If any provision in any Loan Paper is
held to be illegal, invalid, or unenforceable, such provision shall be fully
severable; the appropriate Loan Paper shall be construed and enforced as if
such provision had never comprised a part thereof; and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by such
provision or by its severance therefrom.  Administrative Agent, Facility B
Lenders, and each Restricted Company party to such Loan Paper agree to
negotiate, in good faith, the terms of a replacement provision as similar to
the severed provision as may be possible and be legal, valid, and enforceable.

         11.9    Entirety.  THE RIGHTS AND OBLIGATIONS OF THE RESTRICTED
COMPANIES, FACILITY B LENDERS, AND ADMINISTRATIVE AGENT SHALL BE DETERMINED
SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND INSTRUMENTS, AND ANY PRIOR ORAL
AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED BY AND MERGED INTO SUCH
WRITINGS.  THIS FACILITY B AGREEMENT (AS AMENDED IN WRITING FROM TIME TO TIME)
AND THE OTHER WRITTEN LOAN PAPERS EXECUTED BY ANY RESTRICTED COMPANY, ANY
FACILITY B LENDER, ADMINISTRATIVE AGENT, AND/OR FACILITY A ADMINISTRATIVE AGENT
(TOGETHER WITH ALL FEE LETTERS AS THEY RELATE TO THE PAYMENT OF FEES AFTER THE
CLOSING DATE) REPRESENT THE FINAL AGREEMENT BETWEEN THE RESTRICTED COMPANIES,
FACILITY B LENDERS, ADMINISTRATIVE AGENT, AND/OR FACILITY A ADMINISTRATIVE
AGENT, AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS BY SUCH PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN SUCH PARTIES.

         11.10   Jurisdiction; Venue; Service of Process; Jury Trial.  EACH
PARTY HERETO, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS (AND IN THE
CASE OF BORROWER, FOR EACH OF ITS SUBSIDIARIES), HEREBY (A) IRREVOCABLY SUBMITS
TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS LOCATED IN NEW
YORK, AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN
ANY LEGAL PROCEEDING ARISING OUT OF OR IN CONNECTION WITH THE FACILITY B LOAN
PAPERS AND THE OBLIGATION BY SERVICE OF PROCESS AS PROVIDED BY NEW YORK LAW,
(B) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY LITIGATION

OBLIGATION BROUGHT IN ANY SUCH COURT, (C) IRREVOCABLY WAIVES ANY CLAIMS THAT
ANY LITIGATION BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT

AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY HERETO ARISING OUT OF OR IN
CONNECTION WITH THE FACILITY B LOAN PAPERS OR THE OBLIGATION SHALL BE BROUGHT
IN ONE OF THE AFOREMENTIONED COURTS, AND (G) IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY FACILITY B LOAN PAPER OR THE
TRANSACTIONS CONTEMPLATED THEREBY.  The scope of each of the foregoing waivers
is intended to be all- encompassing of any and all disputes that may be filed
in any court and that relate to the subject matter of this transaction,
including, without limitation, contract claims, tort claims, breach of duty
claims, and all other common law and statutory claims.  Borrower (for itself
and on behalf of each of its Subsidiaries) and each other party to this
Facility B Agreement acknowledge that this waiver is a material inducement to
the agreement of each party hereto to enter into a business relationship, that
each has already relied on this waiver in entering into this Facility B
Agreement, and each will continue to rely on each of such waivers in related
future dealings.  Borrower (for itself and on behalf of each of its
Subsidiaries) and each other party to this Facility B Agreement warrant and
represent that they have reviewed these waivers with their legal counsel, and
that they knowingly and voluntarily agree to each such waiver following
consultation with legal counsel.  THE WAIVERS IN THIS SECTION 11.10 ARE
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, SUPPLEMENTS, AND
REPLACEMENTS TO OR OF THIS OR ANY OTHER FACILITY B LOAN PAPER.  In the event of
Litigation, this Facility B Agreement may be filed as a written consent to a
trial by the court.

         11.11   Amendments, Consents, Conflicts, and Waivers.

                 (a)      Except as otherwise specifically provided, (i) this
         Facility B Agreement may only be amended, modified or waived by an
         instrument in writing executed jointly by Borrower and Determining
         Lenders, and, in the case of any matter affecting Administrative Agent
         (except removal of Administrative Agent as provided in SECTION 10), by
         Administrative Agent, and may only be supplemented by documents
         delivered or to be delivered in accordance with the express terms
         hereof, and (ii) the other Loan Papers (other than Financial Hedges)
         may only be the subject of an amendment, modification, or waiver if
         Borrower and Determining Lenders, and, in the case of any matter
         affecting Administrative Agent (except as set forth above),
         Administrative Agent, have approved same.

                 (b)      Any amendment to or consent or waiver under this
         Facility B Agreement or any Facility B Loan Paper which purports to
         accomplish any of the following must be by an instrument in writing
         executed by Borrower and executed (or approved, as the case may be) by
         each Facility B Lender, and, in the case of any matter affecting
         Administrative Agent, by Administrative Agent: (i) extends the due
         date or decreases the amount of any scheduled payment (other than
         mandatory prepayments) of the Obligation arising under the Facility B
         Loan Papers beyond the date specified in the Facility B Loan Papers;
         (ii) reduces the interest rate or decreases the amount of interest,
         fees, or other sums payable to Administrative Agent or Facility B
         Lenders hereunder (except such reductions as are contemplated by this
         Facility B Agreement); (iii) changes the definition of "APPLICABLE
         MARGIN" (other than changes having the effect of increasing such
         Applicable Margin)," "DETERMINING LENDERS," "PRO RATA," or "PRO RATA
         PART," or (iv) except as otherwise permitted by any Loan Paper, waives
         compliance with, amends, or releases (in whole or in part) any
         guaranty (if any) or releases (in whole or in part) any collateral, if
         any, for the Obligation; or (v) changes this CLAUSE (B) or any other
         matter specifically requiring the consent of all Facility B Lenders
         hereunder.  No amendment or waiver with respect to the definition of
         "TERM LOAN MATURITY DATE" may be made without the consent of all
         Facility B Lenders.

                 (c)      Any conflict or ambiguity between the terms and
         provisions herein and terms and provisions in any other Loan Paper
         shall be controlled by the terms and provisions herein.

                 (d)      No course of dealing nor any failure or delay by
         Administrative Agent, any Facility B Lender, or any of their
         respective Representatives with respect to exercising any Right of
         Administrative Agent or any Facility B Lender hereunder shall operate
         as a waiver thereof.  A waiver must be in writing and signed by
         Administrative Agent and Determining Lenders (or by all Facility B
         Lenders, if required hereunder) to be effective, and such waiver will
         be effective only in the specific instance and for the specific
         purpose for which it is given.

         11.12   Multiple Counterparts.  This Facility B Agreement may be
executed in a number of identical counterparts, each of which shall be deemed
an original for all purposes and all of which constitute, collectively, one
agreement; but, in making proof of this Facility B Agreement, it shall not be
necessary to produce or account for more than one such counterpart.  It is not
necessary that each Facility B Lender execute the same counterpart so long as
identical counterparts are executed by Borrower, each Facility B Lender, and
Administrative Agent.  This Facility B Agreement shall become effective when
counterparts hereof shall have been executed and delivered to Administrative
Agent by each Facility B Lender, Administrative Agent, and Borrower, or, when
Administrative Agent shall have received telecopied, telexed, or other evidence
satisfactory to it that such party has executed and is delivering to
Administrative Agent a counterpart hereof.

         11.13   Successors and Assigns; Assignments and Participations.

                 (a)      This Facility B Agreement shall be binding upon, and
         inure to the benefit of the parties hereto and their respective
         successors and assigns, except that (i) assignments by Borrower are
         subject to the restrictions of SECTION 7.16, and (ii) except as
         permitted under this Section, no Facility B Lender may transfer,
         pledge, assign, sell any participation in, or otherwise encumber its
         portion of the Obligation.

                 (b)      Each Facility B Lender may assign to one or more
         Eligible Assignees all or a portion of its Rights and obligations
         under this Facility B Agreement and the other Facility B Loan Papers
         (including, without limitation, all or a portion of its Borrowings,
         its Notes [to the extent such Facility B Principal Debt owed to such
         Facility B Lender is evidenced by Notes]); provided, however, that:

                          (i)     each such assignment shall be to an Eligible 
                 Assignee;

                          (ii)    except in the case of an assignment to
                 another Facility B Lender or an assignment of all of a
                 Facility B Lender's Rights and obligations under this Facility
                 B Agreement and the other Facility B Loan Papers, any such
                 partial assignment (when aggregated with the amounts of any
                 concurrent assignments under Facility A and/or the 364-Day
                 Facility by the assigning Lender to the same assignee) shall
                 be in an amount at least equal to $10,000,000, but in no event
                 shall an assigned interest in any of Facility A, Facility B,
                 or the 364-Day Facility be less than $1,000,000 (except in the
                 case of an assignment of all of such Facility B Lender's
                 interest in any such facility);

                          (iii)   each such assignment by a Facility B Lender
                 shall be of a constant, and not varying, percentage of all of
                 its Rights and obligations under this Facility B Agreement and
                 the Notes (to the extent the Facility B Principal Debt owed to
                 the assigning Facility B Lender is evidenced by any Notes);
                 and

                          (iv)    the parties to such assignment shall execute
                 and deliver to the Administrative Agent for its acceptance an
                 Assignment and Acceptance Agreement in the form of EXHIBIT E
                 hereto, together with any Notes subject to such assignment (to
                 the extent the Facility B Principal Debt owed to the assigning
                 Facility B Lender is evidenced by any Notes) and a processing
                 fee of $3,500.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance Agreement, the assignee thereunder shall be a party hereto
         and, to the extent of such assignment, have the obligations, Rights,
         and benefits of a Facility B Lender under the Facility B Loan Papers
         and the assigning Facility B Lender shall, to the extent of such
         assignment, relinquish its rights and be released from its obligations
         under the Facility B Loan Papers.  Upon the consummation of any
         assignment pursuant to this Section, but only upon the request of the
         assignor or assignee made through Administrative Agent, Borrower shall
         issue appropriate Notes to the assignor and the assignee, reflecting
         such assignment and acceptance.  If the assignee is not incorporated
         under the laws of the United States of America or a state thereof, it
         shall deliver to Borrower and Administrative Agent certification as to
         exemption from deduction or withholding of Taxes in accordance with
         SECTION 3.20(D).

                 (c)      The Administrative Agent shall maintain at its
         address referred to in SECTION 11.3 a copy of each Assignment and
         Acceptance Agreement delivered to and accepted by it and a register
         for the recordation of the names and addresses of the Facility B
         Lenders and the Facility B Principal Debt owed to

         such Facility B Lenders, and principal amount of the Borrowings owing
         to, each Facility B Lender from time to time (the "REGISTER").  The
         entries in the Register shall be conclusive and binding for all
         purposes, absent manifest error, and Borrower, Administrative Agent
         and the Facility B Lenders may treat each Person whose name is
         recorded in the Register as a Facility B Lender hereunder for all
         purposes of the Facility B Loan Papers.  The Register shall be
         available for inspection by Borrower or any Facility B Lender at any
         reasonable time and from time to time upon reasonable prior notice.
         Upon the consummation of any assignment in accordance with this
         SECTION 11.13, SCHEDULE 2.1 shall automatically be deemed amended (to
         the extent required) by Administrative Agent to reflect the name,
         address, and respective Pro Rata Part of the Facility B Principal Debt
         of the assignor and assignee.

                 (d)      Upon its receipt of an Assignment and Acceptance
         Agreement executed by the parties thereto, together with any Term
         Notes subject to such assignment (to the extent the Facility B
         Principal Debt owed to the assigning Facility B Lender is evidenced by
         any Term Notes) and payment of the processing fee, the Administrative
         Agent shall, if such assignment and acceptance has been completed and
         is in substantially the form of EXHIBIT E hereto, (i) accept such
         Assignment and Acceptance Agreement, (ii) record the information
         contained therein in the Register and (iii) give prompt notice thereof
         to the parties thereto.

                 (e)      Each Facility B Lender may sell participations to one
         or more Persons (each a "PARTICIPANT") in all or a portion of its
         Rights, obligations, or Rights and obligations under this Facility B
         Agreement and related Facility B Loan Papers (including all or a
         portion of Borrowings advanced under Facility B); provided, however,
         that (i) such Facility B Lender's obligations under this Facility B
         Agreement shall remain unchanged; (ii) such Lender shall remain solely
         responsible to the other parties hereto for the performance of such
         obligations; (iii) the Participant shall be entitled to the benefit of
         the yield protection provisions contained in SECTIONS 3.15, 3.19, and
         3.20 (so long as Borrower shall not be obligated to pay any amount in
         excess of the amount that would be due to such Facility B Lender under
         such Sections as though no participations have been made) and the
         right of set-off contained in SECTION 3.13; (iv) Borrower shall
         continue to deal solely and directly with such Facility B Lender in
         connection with such Facility B Lender's Rights and obligations under
         this Facility B  Agreement and the other Facility B Loan Papers and
         such Facility B Lender shall retain the sole Right to enforce the
         obligations of Borrower relating to Borrowings under Facility B and
         its Term Note (to the extent the Facility B Principal Debt owed to
         such Facility B Lender is evidenced by a Term Note) and to approve any
         amendment, modification, or waiver of any provision of this Agreement
         (other than amendments, modifications, or waivers decreasing the
         amount of principal of or the rate at which interest is payable on the
         Facility B Principal Debt, extending any scheduled principal payment
         date or date fixed for the payment of interest on the Facility B
         Principal Debt; and (v) such Facility B Lender shall be solely
         responsible for any withholding taxes or any filing or reporting
         requirements relating to such participation and shall hold Borrower
         and Administrative Agent and their respective successors, permitted
         assigns, officers, directors, employees, agents, and representatives
         harmless against the same.  Except in the case of the sale of a
         participating interest to another Facility B Lender, the relevant
         participation agreement shall not permit the Participant to transfer,
         pledge, assign, sell participations in, or otherwise encumber its
         portion of the Obligation, unless the consent of the transferring
         Facility B Lender (which consent will not be unreasonably withheld)
         has been obtained.

                 (f)      Notwithstanding any other provision set forth in this
         Facility B Agreement, any Facility B Lender may at any time assign and
         pledge all or any portion of its Borrowings and its Term Note (to the
         extent the Facility B Principal Debt owed to such Facility B Lender is
         evidenced by a Term Note) to any Federal Reserve Bank as collateral
         security pursuant to Regulation A and any Operating Circular issued by
         such Federal Reserve Bank.  No such assignment shall release the
         assigning Facility B Lender from its obligations hereunder.

                 (g)      Any Facility B Lender may furnish any information
         concerning the Consolidated Companies in the possession of such
         Facility B Lender from time to time to Eligible Assignees and
         Participants (including prospective Eligible Assignees and
         Participants), subject, however, to the provisions of SECTION 11.15
         hereof.

         11.14   Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances.  Each Restricted Company's obligations under the Loan Papers
shall remain in full force and effect until termination of the Facility A
Commitment and payment in full of the Principal Debt and of all interest, fees,
and other amounts of the Obligation then due and owing, (and termination of all
outstanding LCs with any Facility A Lender, if any, unless such Facility A
Lender shall otherwise consent), except that SECTIONS 3.15, 3.19, 3.20, SECTION
9, and SECTION 11, and any other provisions under the Loan Papers expressly
intended to survive by the terms hereof or by the terms of the applicable Loan
Papers, shall survive such termination.  If at any time any payment of the
principal of or interest on any Term Note, any promissory note issued pursuant
to Facility A, or any other amount payable by Borrower under any Loan Paper is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy, or reorganization of Borrower or otherwise, the obligations of each
Restricted Company under the Loan Papers with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

         11.15   Confidentiality.  All information furnished by or on behalf of
any Restricted Company in connection with or pursuant to this Facility B
Agreement or any of the Loan Papers (including but not limited to in connection
with or pursuant to the negotiation, preparation, or requirements hereof or
thereof), which information has been identified as confidential by any
Restricted Company, shall be held by Administrative Agent, each other Facility
B Agent, each Facility B Lender and each Participant (collectively, the "LENDER
PARTIES") in accordance with its customary procedures for handling confidential
information of this nature and in accordance with safe and sound banking
practices, and no Lender Party shall disclose any of such information to any
other Person; provided that any Facility B Lender, Facility B Agent, or
Participant may make disclosure (a) to its attorneys or accountants, provided
that such Facility B Lender or Participant shall direct such attorneys or
accountants to maintain such information in confidence in accordance with the
provisions of this SECTION 11.15, and shall be responsible if such attorneys
fail to do so, (b) to any affiliate of any Lender Party or as reasonably
required by any prospective bona fide assignee or Participant in connection
with the contemplated transfer of any interest in the Obligation or
participation, so long as any such contemplated assignee or Participant has
agreed in writing (with a copy to Borrower) to be bound by the provisions of
this SECTION 11.15, (c) as required or requested by any Governmental Authority
or representative thereof or as required pursuant to any Law or legal process,
provided that, unless prohibited by Law or court order, such Facility B Lender
or Participant shall give prior notice to Borrower of such disclosure as far in
advance thereof as is practicable (other than disclosure in connection with an
examination of the financial condition of such Person by a Governmental
Authority), (d) in connection with proceedings to enforce the obligation of any
Restricted Company under the Loan Papers, or (e) of any such information that
has become generally available to the public other than through a breach of
this SECTION 11.15 (or of any agreement or obligation to be bound by this
SECTION 11.15) by any Lender Party, any affiliate of any Lender Party, any
prospective assignee or Participant, or their respective attorneys.

         11.16   Restatement of Existing Agreement.  The parties hereto agree
that, on the Closing Date, after all conditions precedent set forth in SECTION
5 have been satisfied or waived: (a) the Obligation (as defined herein)
represents, among other things, the amendment, extension, consolidation, and
modification of the "Obligation" (as defined in the Existing Agreement); (b)
this Facility B Agreement is intended to, and does hereby, restate,
consolidate, renew, extend, amend, modify, supersede, and replace the Existing
Agreement in its entirety; (c) the Term Notes, if any, executed pursuant to
this Facility B Agreement amend, renew, extend, modify, replace, substitute for
and supersede in their entirety (but do not extinguish, the Debt arising under)
the promissory notes issued pursuant to the Existing Agreement, if any, which
existing promissory notes shall be returned to

                          TRANSACTIONS WITH AFFILIATES


1.   WorldCom, Inc. ("WORLDCOM" or "COMPANY") leases approximately 139,700
     square feet of space for its East Rutherford, New Jersey headquarters, of
     which approximately 31,000 square feet is used by Metromedia Company
     ("METROMEDIA"). The Metromedia portion of the rent is approximately
     $692,000 per year. The entire lease is for a 15-year period, with various
     partial termination options. In addition, Metromedia guaranteed all of
     WorldCom's obligations under the lease for the East Rutherford, New Jersey
     headquarters. WorldCom also subleased or leased from certain of its
     affiliates certain additional office space in Secaucus, New Jersey; New
     York, New York; and Columbia, Maryland. The Company is currently evaluating
     these properties and leases to determine what action it will take
     thereunder.

2.   Pursuant to the terms of separate leases of microwave transmission
     facilities, the Company as successor to Metromedia Communications
     Corporation ("MCC") is obligated to make the following estimated minimum
     payments to Metromedia over the remaining terms of the leases, one of which
     expires in 1997 and the others expire in 2001: $18,353,000 (1996),
     $11,367,000 (1997), and $14,547,000 (in the aggregate for the years from
     1998 through 2001). In addition, at the end of the term of each of the
     leases, the Company may purchase the equipment covered by such lease at a
     price to be determined at such date in accordance with the provisions of
     each lease.

3.   Indemnity Agreements - IDB WorldCom, Inc. entered into an indemnity
     agreement with certain of its Affiliates. The agreements indemnify such
     persons against certain liabilities arising out of their service in their
     capacities as directors and/or officers and prevent IDB from modifying its
     indemnification policy in a way that is adverse to any person who is a
     party to one of the agreements.

4.   On August 23, 1995, Metromedia converted its Series 1 Preferred Stock into
     21,876,976 shares of Common Stock and exercised warrants to acquire
     3,106,976 shares of Common Stock and sold its position of 30,849,976 shares
     of Common Stock in a public offering. In connection with the preferred
     stock conversion, the Company made a non-recurring payment of $15.0 million
     to Metromedia, representing a discount to the minimal nominal dividend that
     would have been payable on the Series 1 Preferred Stock prior to the
     September 15, 1996 optional call date of approximately $26.6 million (which
     amount included an annual dividend requirement of $24.5 million plus
     accrued dividends to such call date). The Company did not receive any
     proceeds from the sale of the shares, but did receive approximately $33.7
     million in proceeds from the concurrent exercise of such warrants. In May
     1995, Metromedia exercised its right to purchase approximately 3.1 million
     shares of Common Stock for $30.7 million under purchase warrants.
     Metromedia is a Delaware general partnership, of which the sole partners
     are a trust affiliated with Mr. Kluge and Mr. Subotnick. Ms. Kessell and
     Messrs. Kluge and Subotnick are officers of Metromedia.

                                   EXHIBIT E

                  FORM OF ASSIGNMENT AND ACCEPTANCE AGREEMENT

         Reference is made to the Amended and Restated Facility B Term Loan
Agreement dated as August 6, 1998 (as amended, modified, supplemented, or
restated from time to time, the "FACILITY B AGREEMENT") among WORLDCOM, INC., a
Georgia corporation ("BORROWER"), Facility B Lenders, the Co-Syndication Agents
(each such term as defined in the Facility B Agreement), and NATIONSBANK, N.A.,
as the Administrative Agent under the Facility B Agreement ("ADMINISTRATIVE
AGENT").  Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Facility B Agreement.

         The "ASSIGNOR" and the "ASSIGNEE" referred to on SCHEDULE 1 agree as
follows:

         1.      The Assignor hereby sells and assigns to the Assignee, without
recourse and without representation or warranty except as expressly set forth
herein, and the Assignee hereby purchases and assumes from the Assignor, an
interest in and to the Assignor's Rights and obligations under the Facility B
Agreement and the related Facility B Loan Papers as of the date hereof equal to
the percentage interest specified on SCHEDULE 1.  After giving effect to such
sale and assignment, the Assignor's and the Assignee's Facility B Principal
Debt and the amount of the Borrowings under Facility B owing to each of them
will be as set forth on SCHEDULE 1.

         2.      The Assignor (i) represents and warrants that it is the legal
and beneficial owner of the interest being assigned by it hereunder and that
such interest is free and clear of any adverse claim; (ii) makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with the
Facility B Loan Papers or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of the Facility B Loan Papers or any other
instrument or document furnished pursuant thereto; (iii) makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of any party to any Facility B Loan Paper or the
performance or observance by any such party of any of its obligations under the
Facility B Loan Papers or any other instrument or document furnished pursuant
thereto; and (iv) attaches the Notes held by the Assignor (to the extent the
Facility B Principal Debt being assigned and owed to the Assignor is evidenced
by Notes) and requests that Administrative Agent exchange such Notes for new
Notes if so requested by either the Assignor or Assignee.  Such new Notes shall
be prepared in accordance with the provisions of SECTION 3.1(B) of the Facility
B Agreement and will reflect the respective Principal Debt of the Assignee and
the Assignor after giving effect to this Assignment and Acceptance.

         3.      The Assignee (i) confirms that it has received a copy of the
Facility B Agreement, together with copies of the Current Financials and such
other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into this Assignment and Acceptance; (ii)
agrees that it will, independently and without reliance upon the Administrative
Agent, the Assignor, or any other Facility B Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the Facility
B Agreement; (iii) confirms that it is an Eligible Assignee; (iv) appoints and
authorizes Administrative Agent to take such action as Administrative Agent on
its behalf and to exercise such powers and discretion under the Facility B
Agreement as are delegated to Administrative Agent by the terms thereof,
together with such powers and discretion as are reasonably incidental thereto;
(v) agrees that it will perform in accordance with their terms all of the
obligations that by the terms of the Facility B Agreement are required to be
performed by it as a Facility B Lender; and (vi) attaches any U.S. Internal
Revenue Service or other forms required under SECTION 3.20(D) of the Facility B
Agreement.

         4.      Following the execution of this Assignment and Acceptance, it
will be delivered to Administrative Agent for acceptance and recording by the
Administrative Agent.  The effective date for this Assignment and Acceptance
(the "EFFECTIVE DATE") shall be the date of acceptance hereof by Administrative
Agent, unless otherwise specified on SCHEDULE 1.

         5.      Upon such acceptance and recording by Administrative Agent, as
of the Effective Date, (i) the Assignee shall be a party to the Facility B
Agreement and, to the extent provided in this Assignment and Acceptance, have
the Rights and obligations of a Facility B Lender thereunder, and (ii) the
Assignor shall, to the extent provided in this Assignment and Acceptance,
relinquish its Rights and be released from its obligations under the Facility B
Agreement.

         6.      Upon such acceptance and recording by Facility B
Administrative Agent, from and after the Effective Date, Administrative Agent
shall make all payments under the Facility B Agreement, the Notes (to the
extent the Facility B Principal Debt owed to the Assignee is evidenced by
Notes), and loan accounts in respect of the interest assigned hereby
(including, without limitation, all payments of principal, interest and
commitment fees and other fees with respect thereto) to the Assignee.  The
Assignor and Assignee shall make all appropriate adjustments in payments under
the Facility B Agreement and the other Facility B Loan Papers for periods prior
to the Effective Date directly between themselves.

         7.      Unless the Assignee is a Facility B Lender or an Affiliate of
a Facility B Lender (and this sale and assignment is not made in connection
with the sale of such Affiliate), this Assignment and Acceptance is conditioned
upon the consent of Borrower and Administrative Agent pursuant to the
definition of "Eligible Assignee" in the Facility B Agreement.  The execution
and delivery of this Assignment and Acceptance by Borrower and Administrative
Agent is evidence of this consent.

         8.      As contemplated by SECTION 11.13(B)(V) of the Facility B
Agreement, the Assignor or the Assignee (as determined between the Assignor and
the Assignee) agrees to pay to Administrative Agent for its account on the
Effective Date in federal funds a processing fee of $3,500.

         9.      THIS ASSIGNMENT AND ACCEPTANCE SHALL BE GOVERNED BY, AND SHALL
BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

         10.     This Assignment and Acceptance may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement.  Delivery of an
executed counterpart of SCHEDULE 1 to this Assignment and Acceptance by
telecopier shall be effective as delivery of a manually executed counterpart of
this Assignment and Acceptance.

         IN WITNESS WHEREOF, the Assignor and the Assignee have caused SCHEDULE
1 to this Assignment and Acceptance to be executed by their officers thereunto
duly authorized as of the date specified thereon.

(the "FACILITY B AGREEMENT"), among Borrower, the lenders named on SCHEDULES
2.1 to each of the Facility A Agreement and the Facility B Agreement
("LENDERS"), NationsBank, N.A., (as successor in interest by merger to
NationsBank of Texas, N.A.), as the "Administrative Agent" under the Facility A
Agreement (in such capacity, the "FACILITY A ADMINISTRATIVE AGENT") or as the
"Administrative Agent" under the Facility B Agreement (in such capacity, the
"FACILITY B ADMINISTRATIVE AGENT"), the other "Facility A Agents" under the
Facility A Agreement, and the "Facility B Agents" under the Facility B
Agreement.

         This opinion is delivered pursuant to SECTION 5.1 of the Facility A
Agreement and SECTION 5 of  the Facility B Agreement and PARAGRAPHS 8 of
SCHEDULES 5.1 and 5, respectively, to the Facility A Agreement and the Facility
B Agreement.  Unless otherwise defined, each capitalized term used herein has
the meaning given to such term in the Facility A Agreement and the Facility B
Agreement.

         In arriving at the opinions expressed below, I or attorneys employed
by Borrower and acting under my supervision have examined such corporate
documents and records of the Consolidated Companies and such certificates of
public officials and of officers of the Consolidated Companies, other
documents, and matters of law as I deemed necessary or appropriate, including,
without limitation, originals or copies (or, with respect to the Notes under
the Facility A or Facility B Agreement (collectively, the "NOTES") only, the
forms of Notes attached as Exhibits to the Facility A and the Facility B
Agreement) of (i) the Facility A Agreement, (ii) the Facility B Agreement, and
(iii) to the extent any Notes are executed and delivered on the Closing Date or
immediately subsequent thereto, such Notes (all of the foregoing, collectively,
the "TRANSACTION DOCUMENTS").

         In rendering the opinions expressed below, I have assumed with your
permission, without independent investigation or inquiry, (a) the authenticity
of all documents submitted to me as originals, (b) the genuineness of all
signatures on all documents that I have examined (other than those of any
officer of any Consolidated Company who signed in my presence and Bernard J.
Ebbers, Charles T. Cannada, Scott D. Sullivan, and any other officer signing
the incumbency provisions of officers' certificates delivered in connection
with the Loan Papers), (c) the conformity

to authentic originals of documents submitted to me as certified, conformed or
photostatic copies, and (d) compliance by the Facility A Administrative Agent,
the Facility B Administrative Agent, the other Agents under Facility A, the
other Agents under Facility B, and the Lenders with their respective covenants
and undertakings contained in the Transaction Documents.

         As to certain matters of New York law, I understand you will rely
solely upon the opinions of Bryan Cave LLP.

         Based upon the foregoing, and subject to the qualifications and
limitations herein contained, it is my opinion that:

         1.      Borrower (a) is a corporation validly existing and in good
standing under the Laws of its state of incorporation (based solely upon my
review of good standing certificates issued by such state with respect to such
corporation), and (b) possesses all requisite corporate authority and power to
conduct its business and execute, deliver, and comply with the terms of the
Transaction Documents, which have been duly authorized and approved by all
necessary corporate action and for which, to the best of my knowledge, no
approval or consent of any Person or Governmental Authority is required which
has not been obtained, except where the failure to obtain would not be a
Material Adverse Event.

         2.      Each of the Transaction Documents have been duly executed and
delivered by Borrower.

         3.      The Transaction Documents evidence the valid and legally
binding obligations of Borrower, enforceable against Borrower in accordance
with their terms, except as the enforcement may be limited by Debtor Relief
Laws and except that the remedies available with respect thereto may be subject
to general principles of equity (regardless of whether such remedies are sought
in a proceeding in equity or at law).

         4.      The execution, delivery and performance of and compliance with
the terms of the Transaction Documents will not cause Borrower to be in
violation of its Second Amended and Restated Articles or Certificates of
Incorporation or Bylaws.

         5.      The execution, delivery, and the performance of and compliance
with the terms of the Transaction Documents will not cause Borrower to be in
violation of any Laws applicable to it, other than such violations which will
not, individually or collectively, be a Material Adverse Event.

         6.      No Restricted Company is involved in, nor am I aware of the
threat of, any Litigation which is reasonably likely to be determined adversely
to any Restricted Company and, if so adversely determined, would be a Material
Adverse Event.  There are no outstanding orders or judgments for the payment of
money (not paid or fully covered by insurance) in excess of $100,000,000
(individually or collectively) or any warrant of attachment, sequestration, or
similar proceeding against any Restricted Company's assets having a value
(individually or collectively) of $100,000,000 or more, which is not either (a)
stayed on appeal, (b) being diligently contested in good faith by appropriate
proceedings with adequate reserves having been set aside on the books of such
Restricted Company in accordance with GAAP, or (c) dismissed by a court of
competent jurisdiction.

         7.      To the best of my knowledge, after reasonable investigation,
the execution, delivery, and the performance of and compliance with the terms
of the Transaction Documents will not cause Borrower to be in default under any
material, written, or oral agreements, contracts, commitments, or
understandings to which any Restricted Company is a party, other than such
defaults or potential defaults which will not, individually or collectively, be
a Material Adverse Event.





                                        2
                                                       FACILITY B - EXHIBIT F-1
<PAGE>   81
         8.      (a) No Employee Plan has incurred an accumulated funding
deficiency (as defined in the Code and ERISA), (b) neither Borrower nor any
ERISA Affiliate has incurred material liability which is currently due and
remains unpaid to the PBGC or to an Employee Plan in connection with any such
Employee Plan, (c) neither Borrower nor any ERISA Affiliate has withdrawn in
whole or in part from participation in a Multiemployer Plan, (d) Borrower has
not engaged in any prohibited transaction (as such term is defined in ERISA or
the Code) which would be a Material Adverse Event, and (e) to the best of my
knowledge, after reasonable investigation, no Reportable Event has occurred
which is likely to result in the termination of any Employee Plan.

         This opinion is limited in all respect to the laws of the State of
Georgia and the federal laws of the United States of America.

         I note that the Transaction Documents are to be governed by the laws
of the State of New York.  Accordingly, for purposes of rendering this opinion
as to the enforceability of the Transaction Documents, I have assumed that the
substantive laws of the State of New York are identical to the substantive laws
of the State of Georgia.

         The foregoing opinions are also subject to the following exceptions
and qualifications: I express no opinion

                 (a)      with respect to the availability of the remedies of
         specific performance or injunction, or other remedies requiring the
         exercise of judicial discretion;

                 (b)      as to the effect of the compliance or noncompliance
         of Lenders with any state or federal laws or regulations applicable to
         any Lender's legal or regulatory status or the nature of such Lender's
         business;

                 (c)      as to the enforceability of any provisions contained
         in the Transaction Documents that (i) purport to make void any act in
         contravention thereof, (ii) purport to authorize a party to act in its
         sole discretion, (iii) relate to the effect of laws or regulations
         that may be enacted in the future, (iv) require waivers or amendments
         to be made only in writing or (v) purport to effect waivers of
         constitutional, statutory or equitable rights or the effect of
         applicable laws;

                 (d)      regarding the enforceability of the waivers in the
         Transaction Documents of the right to demand a trial by jury and with
         respect to selection of a venue;

                 (e)      as to the enforceability of any provisions in the
         Transaction Documents to the effect that the acceptance of a past due
         installment or other performance by Borrower shall not be deemed a
         waiver of the right to accelerate the indebtedness;

                 (f)      as to the enforceability of any provisions in the
         Transaction Documents relating to (i) set off, (ii) self help or (iii)
         evidentiary standards or other standards by which the Transaction
         Documents are to be construed;

                 (g)      with regard to any provisions of the Transaction
         Documents whereby a party purports to indemnify another party against
         its own negligence or misconduct; and

                 (h)      as to matters subject to the jurisdiction of the FCC,
         state public utility commissions, or any other communications or
         similar regulatory authorities.

         This opinion is addressed to you solely for your use in connection
with the transactions contemplated by the Transaction Documents, and no person
other than the Facility A Administrative Agent, the Facility B Administrative

                  FORM OF OPINION OF SPECIAL NEW YORK COUNSEL
                                  [BRYAN CAVE]


                                 August 6, 1998


NationsBank, N.A.,
         as Administrative Agent for Facility A and
         Administrative Agent for Facility B


Each of the Facility A Agents and the Facility B Agents and Lenders named on
SCHEDULES 2.1 to each of the Facility A Agreement and the Facility B Agreement
referred to below:

Ladies and Gentlemen:

         We have acted as special New York counsel to WorldCom, Inc., a Georgia
corporation (the "BORROWER"), in connection with the negotiation, preparation,
and execution of the Amended and Restated Facility A Revolving Credit Agreement
(the "FACILITY A AGREEMENT") dated as of August 6, 1998, the Amended and
Restated Facility B Term Loan Agreement (the "FACILITY B AGREEMENT") dated as
of August 6, 1998, and the related Loan Papers by and among the Borrower, the
Lenders referred to on SCHEDULES 2.1 of each of the Facility A Agreement and
the Facility B Agreement ("LENDERS"), NationsBank, N.A. (as successor in
interest by merger to NationsBank of Texas, N.A.), as the "Administrative
Agent" under the Facility A Agreement (the "FACILITY A ADMINISTRATIVE AGENT")
and as the "Administrative Agent" under the Facility B Agreement (the "FACILITY
B ADMINISTRATIVE AGENT"), and the other "Facility A Agents" under the Facility
A Agreement and the "Facility B Agents" under the Facility B Agreement
(collectively, "AGENTS"):

         This opinion is furnished to you pursuant to SECTION 5.1 of the
Facility A Agreement and SECTION 5 of the Facility B Agreement and PARAGRAPHS 8
of SCHEDULES 5.1 and SCHEDULE 5, respectively, to the Facility A Agreement and
the Facility B Agreement.  Capitalized terms used but not otherwise defined
herein shall have the meanings given to them in the Facility A Agreement and
the Facility B Agreement.

         For purposes of the opinions expressed herein, we have examined the
following documents:

         (a)     A copy of the Facility A Agreement;

         (b)     A copy of the Facility B Agreement;

         (c)     A copy of the form of the Notes issuable under Facility A or
                 Facility B;

         (d)     A copy of a Secretary's Certificate for the Borrower dated as
                 of the date hereof (the "SECRETARY'S CERTIFICATE"), including
                 the following exhibits appended to each such Secretary's
                 Certificate:

                 Exhibit A        Second Amended and Restated Articles of
                                  Incorporation 
                 Exhibit B        Certificate of Existence





                                                       FACILITY B - EXHIBIT F-2
<PAGE>   84
                 Exhibit C        By-Laws
                 Exhibit D        Authorizing Resolutions/Unanimous Written 
                                  Consents

         The documents described under Paragraphs (a) through (c) above are
sometimes collectively referred to herein as the "TRANSACTION DOCUMENTS".  We
have not made any independent investigation or inquiries as to (i) the accuracy
or completeness of any factual matters contained in the exhibits or schedules
to any of the Transaction Documents, (ii) any other instruments or other
documents delivered by the Borrower in connection with any of the Transaction
Documents, or (iii) title to, or ownership of any property, real or personal,
or the compliance or non-compliance of such properties with applicable laws,
regulations, and codes.

         In rendering this opinion, we have assumed the accuracy of, and we
have relied as to matters of fact upon, the representations and warranties made
by the Borrower in the Transaction Documents insofar as they relate to factual
matters and upon factual representations as to certain matters contained in the
Secretary's Certificate and other certificates signed by officers of the
Borrower and certain of the other Restricted Companies.  We have assumed, and
we have relied upon, (i) the genuineness of all signatures on documents,
instruments, and certificates reviewed by us, (ii) the accuracy and
authenticity of all documents, instruments, and certificates reviewed by us,
(iii) the legal competence of all natural persons who are signatories thereto,
(iv) the conformity to authentic original documents of all documents,
instruments, and certificates submitted to us as certified, conformed or
photostatic copies, and (v) the due execution and delivery of all documents
(other than the Transaction Documents) where due execution and delivery are a
prerequisite to the effectiveness thereof.  We have further assumed that each
of the Facility A Agreement and the Facility B Agreement have been duly
authorized, executed, and delivered by the Facility A Administrative Agent or
the Facility B Administrative Agent (as the case may be), the Agents, and the
Lenders and that the Facility A Administrative Agent or the Facility B
Administrative Agent (as the case may be), the Agents, and the Lenders have the
requisite corporate power and authority to execute, deliver and perform each of
the Facility A Agreement and the Facility B Agreement.

         Based on the foregoing and in reliance thereon, and subject to the
assumptions, exceptions, limitations and qualifications set forth in this
opinion, we are of the opinion that:

         (1)     Each of the Transaction Documents constitute the valid and
                 legally binding obligation of the Borrower, enforceable
                 against Borrower in accordance with its terms.

         (2)     The execution, delivery, and performance by the Borrower of
                 each of the Transaction Documents to which it is a party will
                 not violate any applicable Law of the State of New York,
                 except for any such violations which could not reasonably be
                 expected to cause, either individually or in the aggregate, a
                 Material Adverse Event.

         (3)     The execution, delivery, and performance by Borrower of the
                 Transaction Documents do not require the consent or
                 authorization of, or filing with any New York Governmental
                 Authority.

         (4)     No Restricted Company is an "investment company" or a company
                 "controlled" by an "investment company" within the meaning of
                 the Investment Company Act of 1940, as amended.

         (5)     No Restricted Company is a "holding company" or a "subsidiary
                 company" of a "holding company" within the meaning of the
                 Public Utility Holding Company Act of 1935, as amended.

         (6)     No Restricted Company is subject to regulation under the
                 Interstate Commerce Act, as amended.

<PAGE>   85
         (7)     The application of the proceeds of the Borrowings under
                 Facility A and Facility B by the Borrower in accordance with
                 the terms of the Facility A Agreement and the Facility B
                 Agreement will not violate Regulation U.

         This opinion is subject to the additional exceptions, limitations and
qualifications set forth below:

         Enforceability of the Transactions Documents are subject to:

         (1)     the effect of bankruptcy, insolvency, reorganization,
                 receivership, moratorium and other similar laws affecting the
                 rights and remedies of creditors generally, including:

                 (a)      the United States Bankruptcy Code of 1978, as
                          amended, and thus comprehends, among others, matters
                          of turn-over, automatic stay, avoiding powers,
                          fraudulent transfer, preference, discharge,
                          conversion of a non-recourse obligation into a
                          recourse claim, limitations on ipso facto and
                          anti-assignment clauses and the coverage of
                          pre-petition security agreements applicable to
                          property acquired after a petition is filed.

                 (b)      all other federal and state bankruptcy, insolvency,
                          reorganization, receivership, moratorium, arrangement
                          and assignment for the benefit of creditors laws that
                          affect the rights and remedies of creditors
                          generally.

                 (c)      state fraudulent transfer and conveyance laws.

                 (d)      judicially developed doctrines relevant to any of the
                          foregoing laws, such as substantive consolidation of
                          entities.

         (2)     the effect of general principles of equity, whether applied by
                 a court of law or equity, including principles:

                 (a)      governing the availability of specific performance,
                          injunctive relief or other equitable remedies, which
                          generally place the award of such remedies, subject
                          to certain guidelines, in the discretion of the court
                          to which application for such relief is made.

                 (b)      affording equitable defenses (e.g., waiver, laches
                          and estoppel) against a party seeking enforcement.

                 (c)      requiring good faith and fair dealing in the
                          performance and enforcement of a contract by the
                          party seeking its enforcement.

                 (d)      requiring reasonableness in the performance and
                          enforcement of an agreement by the party seeking
                          enforcement of the contract.

                 (e)      requiring consideration of the materiality of a
                          breach and the consequences of the breach to the
                          party seeking enforcement.

                 (f)      requiring consideration of the impracticability or
                          impossibility of performance at the time of attempted
                          enforcement.

<PAGE>   86
                 (g)      affording defenses based upon the unconscionability
                          of the enforcing party's conduct after the parties
                          have entered into the contract.

         (3)     the effect of generally applicable rules of law that:

                 (a)      limit or affect the enforcement of provisions of a
                          contract that purport to require waiver of the
                          obligations of good faith, fair dealing, diligence
                          and reasonableness.

                 (b)      provide that forum selection clauses in contracts are
                          not necessarily binding on the court(s) in the forum
                          selected.

                 (c)      limit the availability of a remedy under certain
                          circumstances where another remedy has been elected.

                 (d)      limit the right of a creditor to use force or cause a
                          breach of the peace in enforcing rights.

                 (e)      limit the enforceability of provisions releasing,
                          exculpating or exempting a party from, or requiring
