                                   ARTICLE II
                           LOANS AND LETTERS OF CREDIT

          SECTION  2.01.  Agreement  to Lend.  (a) Each  Term  Lender  severally
agrees,  on the terms and conditions  hereinafter set forth, to make on the Term
Loan  Funding  Date a Term  Loan  in the  amount  of  such  Lender's  Term  Loan
Commitment Amount.

          (b)  Each  Revolving  Lender  severally   agrees,  on  the  terms  and
conditions  hereinafter set forth, to make on and after the Initial Funding Date
and until but not including the Revolving Credit  Commitment  Termination  Date,
one or more  Revolving  Loans to the  Borrowers  in an amount  not to exceed the
Revolving Loan Commitment Amount of such Revolving Lender less such Lender's Pro
Rata Share of the Letter of Credit Obligations.

          (c) At any time that the Total  Leverage  Ratio is greater than 6:1 as
determined  by  reference  to the  financial  statements  delivered  pursuant to
Section 5.06,  the maximum  amount of Revolving  Loans that may be borrowed from
all Revolving  Lenders shall not exceed the Borrowing Base and transaction costs
incurred in connection  with the  execution and delivery of the Loan  Documents,
minus,  if the Term  Loans  have not yet been  made,  the Term  Loan  Commitment
Amounts of all Term Lenders, and otherwise, the outstanding principal balance of
the Term Loans.

          (d) Term  Loans  which are repaid or  prepaid  may not be  reborrowed.
Revolving Loans which are repaid or prepaid may be reborrowed.

          SECTION  2.02.  Loans.  (a) The proceeds of the Loans shall be used by
the Borrowers to purchase Telecommunications Equipment, to pay transaction costs
incurred in connection with the execution,  delivery and performance of the Loan
Documents,  and for working capital and other general corporate purposes, all as
specified in the Notice of Borrowing and in accordance  with the Milestone Plan;
provided,  however,  that at any time that the Total  Leverage  Ratio is greater
than 6:1 as  determined  by  reference  to the  financial  statements  delivered
pursuant to Section 5.06,  proceeds of Loans may be used only to pay transaction
costs  incurred  in  connection  with the  execution  and  delivery  of the Loan
Documents and to purchase  Telecommunications  Equipment.  Loans with respect to
Telecommunications Equipment purchases may not be made to finance (i) soft costs
(including  installation,  delivery and engineering  costs) in excess of fifteen
percent (15%) of the invoiced price for the related Switch Equipment or (ii) any
support or installation  costs associated with an operational  system that would
not be capitalized in accordance with GAAP.

          (b) Each  Base Rate Loan  shall be in a  minimum  principal  amount of
$1,000,000 and increments of $250,000 in excess  thereof.  Each LIBOR Loan shall
be in a minimum  principal  amount of $5,000,000 and increments of $1,000,000 in

                                       22


          SECTION 2.03. Procedure for Loan Request and Borrowing Commitment. (a)
A Borrower  requesting  a Loan shall  deliver to the Agent a Notice of Borrowing
substantially in the form of Exhibit H-1 attached hereto on or before 11:00 a.m.
(New York time) at least five (5) Business  Days prior to the date on which such
Loan is requested to be made if such Loan is requested to be a LIBOR Loan and at
least two (2) Business Days prior to the date on which such Loan is requested to
be made if such Loan is requested  to be a Base Rate Loan,  which  notice,  once
given,  shall be  irrevocable.  The Revolving  Loans made on the Initial Funding
Date shall be Base Rate Loans and thereafter may be continued as Base Rate Loans
or converted into LIBOR Loans in the manner provided in Section 2.06 and subject
to the other conditions and limitations  therein set forth and set forth in this
Article II. In the case of a Loan the proceeds of which will be used to purchase
or reimburse  any  Borrower  for  Telecommunications  Equipment  (including  any
Telecommunications  Equipment  being  purchased or  reimbursed  under the Lucent
Purchase Agreement),  the Notice of Borrowing will include a schedule supporting
one hundred  percent  (100%) of  Telecommunications  Equipment  requested  to be
funded. Such schedule will detail all invoices for equipment, third party labor,
permits,  other  third  party costs and all  capitalized  internal  costs of the
Borrowers  with respect to such  Telecommunications  Equipment  permitted  under
GAAP.  All  invoices  over  $25,000  will be attached to such  schedule and when
combined with the above  described  capitalized  internal  costs will support at
least seventy percent (70%) of the total requested funding. In addition,  if the
Telecommunications  Equipment is being purchased or reimbursed  under the Lucent
Purchase  Agreement,  a  certificate  of delivery and  acceptance in the form of
Exhibit R shall be  attached to the Notice of  Borrowing.  In the case of a Loan
the  proceeds  of  which  will be  used to pay or  reimburse  any  Borrower  for
transaction  costs,  the Notice of Borrowing  will include a copy of the invoice
from the provider of the service or other appropriate supporting  documentation.
In the case of a Loan, the proceeds of which will be used for working capital or
other  general  corporate  purposes,  the  Notice of  Borrowing  will  contain a
certification that the making of such Loan does not violate any provision of the
Indenture.  The Notice of Borrowing shall,  with respect to any Loans requested,
specify  whether such requested  Loans are to be Base Rate Loans or LIBOR Loans,
and if such requested Loans are to be LIBOR Loans, the requested Interest Period
for such Loans.

          (b) The Agent agrees,  promptly upon receipt of a Notice of Borrowing,
to notify  each  Revolving  or Term  Lender  of the date and  amount of the Loan
proposed  thereunder and the amount of such Lender's Pro Rata Share therein.  So
long as no Event of Default has occurred and is continuing and upon  fulfillment
of the applicable conditions set forth in Article IV, each such Lender severally
agrees,  on or before  12:00 P.M.  (New York time) on the date of each  proposed
Loan, to pay into the Payment Account, an amount equal to such Lender's Pro Rata
Share of such Loan in dollars and in same day funds.  After the Agent's  receipt
of such Lender's Loan proceeds,  the Agent shall make available such proceeds to
the Borrower  requesting the Loan or the Person  entitled to payment  thereof at
the bank  account(s)  specified in the Notice of Borrowing on the date specified
in such Notice of Borrowing in Dollars in immediately available funds.

          (c) Unless the Agent has received  written  notice from a Lender prior
to the date of any proposed Loan that such Lender will not make available to the
Agent  such  Lender's  Pro Rata Share of such  Loan,  the Agent may,  but is not
obligated  to,  assume that such Lender has made its Pro Rata Share of such Loan
available to the Agent on the date of such Loan in accordance with paragraph (b)
above, and the Lenders may, in reliance upon such assumption,  make available to
the Borrower on such date a corresponding amount. If such Pro Rata Share is not,


                                       23


in fact,  paid to Agent by such Lender  when due,  the Agent will be entitled to
recover  such amount on demand from such Lender or the Borrower  which  received
the  proceeds of such Loan  without  set-off,  counterclaim  or deduction of any
kind, together with interest thereon,  for each day from the date such amount is
made  available  to such  Borrower  until the date such  amount is repaid to the
Agent  either  by such  Borrower  or such  Lender,  at,  (1) in the case of such
Borrower, the interest rate applicable to such Loan, and (2) in the case of such
Lender,  the Federal Funds  Effective  Rate.  Nothing in this Section 2.03(c) or
elsewhere  in this  Agreement  or the other  Loan  Documents  shall be deemed to
require  Agent to advance funds on behalf of any Lender or to relieve any Lender
from its  obligation  to fulfill its  Commitment  hereunder or to prejudice  any
rights that the  Borrower may have against any Lender as a result of any default
by such Lender  hereunder.  Without limiting the foregoing,  with respect to any
Lender which for any reason fails to make timely payment to the Agent of its Pro
Rata Share of any Loan,  the Agent,  in  addition to other  rights and  remedies
which it may have,  shall be entitled  to withhold or set off from any  payments
due to such Lender hereunder,  an amount equal to the Pro Rata Share required to
have been paid by such Lender plus interest as described  above, and to withhold
from such Lender any right of consent provided to such Lender by Article V or VI
of this  Agreement and to bring an action or suit against such Lender in a court
of competent jurisdiction to recover such Pro Rata Share thereof and any related
interest  thereon.  If such Lender  shall repay to the Agent such  corresponding
amount, such amount so repaid shall constitute such Lender's applicable Pro Rata
Share of such Loan for purposes of this Agreement.  If both such Lender and such
Borrower shall have repaid the  corresponding  amount,  the Agent shall promptly
return to such Borrower its corresponding amount.

          (d) The  Borrowers  commit to the Lenders to request  Loans to be made
(1) on a date not later than the Term Loan Funding Date, of at least $75,000,000
in the aggregate,  the initial $75,000,000 of which shall constitute Term Loans;
provided,  that the Borrowers  shall not be permitted to request Loans in excess
of $75,000,000  until they have provided each item required to be delivered with
respect to Systems located outside of the First Eight Cities, including, without
limitation,  the  mortgages  and third  party  agreements  required  pursuant to
Section 4.02(k),  as further described in Section 5.08, (2) during calendar year
1999 in an aggregate  amount of at least  $80,000,000,  (3) during calendar year
2000 in an aggregate  amount of at least  $80,000,000,  and (4) during  calendar
year 2001 in an aggregate  amount equal to the undrawn  portion of the Revolving
Loan Commitment Amount.

          SECTION 2.04.  The Notes.  Each Borrower  shall execute and deliver to
each Revolving  Lender a Revolving Loan Note and to each Term Lender a Term Loan
Note to evidence the  Commitment of that Lender.  Each Revolving Loan Note shall
be in the  principal  amount  of the  Revolving  Loan  Commitment  Amount of the
applicable  Lender,  dated the  Initial  Funding  Date,  stated to mature on the
Revolving Credit  Commitment  Termination Date and  substantially in the form of
Exhibit E-1.  Each Term Loan Note shall be in the  principal  amount of the Term
Loan Commitment Amount of the applicable Term Lender,  dated the Initial Funding
Date,  stated to mature on the Term Loan Termination  Date and  substantially in


                                       24


the form of Exhibit  E-2.  The Notes  payable to a Lender  shall  represent  the
obligation of such Borrower to pay the amount of each  Lender's  Revolving  Loan
Commitment  Amount or Term Loan  Commitment  Amount or, if less,  the applicable
Lender's Pro Rata Share of the aggregate unpaid principal amount of all Loans to
such Borrower and Letter of Credit Obligations  incurred by such Lender together
with interest  thereon as prescribed  in Section 2.05.  The aggregate  principal
amount of all the Notes shall not exceed the  aggregate  Commitments  of all the
Lenders.  The  Agent is  hereby  authorized  by such  Borrower  to record in the
Register  the date and amount of each  Revolving  Loan or Term Loan made to such
Borrower,  as  applicable,  and to record  therein  the date and  amount of each
payment  on each  Loan made to such  Borrower,  and such  recordations  shall be
conclusive  evidence  against such  Borrower of the amounts owing to the Lenders
with respect to the Loans in the absence of manifest error;  provided,  however,
that the failure of the Agent to register any such  information on such schedule
shall not in any manner  affect the  obligation  of such  Borrower  to repay the
Loans made to such Borrower in accordance with the terms of this Agreement.

          SECTION  2.05.  Interest  on  Loans.  (a)  General.   Subject  to  the
provisions of Sections 2.05(b),  2.06 and 2.07, each Loan shall bear interest at
the  rate per  annum  equal to (i) the Base  Rate  plus the  Applicable  Margin,
computed on the basis of a 365 or 366 day year, as applicable,  or (ii) the LIBO
Rate plus the  Applicable  Margin,  computed on the basis of a 360 day year,  as
selected  by the  Borrowers  in the  Notices  of  Borrowing  and the  Notices of
Continuation/Conversion.

          (b) Default Interest.  If any Borrower shall default in the payment of
the  principal  of or  interest  on any Loan or any other  amount  becoming  due
hereunder  on its due date and such  default  shall  continue  uncured for three
days,  then the  Borrowers  shall,  on demand,  from the Agent,  thereafter  pay
interest on all Loans at a rate that is four percent (4.00%) per annum above the
rates of interest  otherwise payable on all the Loans from the date such payment
is due to the date such payment  default is either cured or waived in writing by
the  Requisite  Lenders.  If any  other  Event of  Default  shall  occur  and be
continuing  and  shall  be  declared  by the  Agent  upon the  direction  of the
Requisite Lenders, then the Borrowers shall, on demand,  thereafter pay interest
on all the Loans at a rate that is two percent (2.00%) per annum above the rates
of interest  otherwise  payable on the Loans from the date of the  occurrence of
such  Event of Default  until the date such  Event of Default  has been cured or
waived  in  writing  by the  Requisite  Lenders;  provided,  that if an Event of
Default  described  in the first  sentence of this clause (b) shall occur at any
time that an Event of Default described in this second sentence has occurred and
is continuing, then the rate of interest described in the first sentence of this
clause (b) shall apply.  After the occurrence and during the  continuance of any
Event  of  Default,  the  Borrowers  shall  be  subject  to the  limitations  on
borrowings of,  conversions  into and  continuations as LIBOR Loans set forth in
Section 2.07(g).

          SECTION  2.06.   Conversion  or  Continuation.   (a)  Subject  to  the
provisions of Section 2.07,  each Borrower  shall have the option (i) to convert
(A) all or any part of its outstanding  Term Loans or (B) all or any part of its
outstanding  Revolving  Loans,  in a minimum  amount of $5,000,000  and integral
multiples of $1,000,000 in excess of that amount,  from a Term Loan or Revolving
Loans that are Base Rate Loans to LIBOR Term Loans or LIBOR Revolving  Loans, as


                                       25


the case may be;  (ii) to convert  (A) all or any part of its  outstanding  Term
Loan or (B) all or any part of its outstanding  Revolving Loans from LIBOR Loans
to Base Rate Loans on the expiration of the Interest Period applicable  thereto;
and  (iii)  upon  the  expiration  of  any  Interest  Period  applicable  to its
outstanding LIBOR Term Loan or any outstanding LIBOR Revolving Loan, to continue
(A)  all of  such  LIBOR  Term  Loan or (B)  all or any  portion  of such  LIBOR
Revolving  Loan equal to  $5,000,000  and integral  multiples of  $1,000,000  in
excess  of that  amount  as a  LIBOR  Term  Loan or  LIBOR  Revolving  Loan,  as
applicable;  provided, however, that no outstanding Loans may be converted into,
or  continued  as, LIBOR Loans when any Default or Event of Default has occurred
and is continuing. Any conversion or continuation made with respect to less than
the entire  outstanding  balance of a Borrower's  Revolving  Loans or Term Loans
must be applied pro rata to such  Borrower's  Revolving  Loans or Term Loans, as
applicable,  according to the  outstanding  principal  balance of such Revolving
Loans or Term Loans.

          (b) Whenever a Borrower elects to convert or continue Loans under this
Section  2.06,  such  Borrower  shall  deliver  to the  Agent a  written  notice
substantially  in the form of that attached  hereto as Exhibit H-2 (a "Notice of
Conversion/ Continuation"), signed by an authorized officer of such Borrower (i)
no later than 10:00 a.m. (New York time) two (2) Business Days in advance of the
requested conversion date, in the case of a conversion into Base Rate Loans, and
(ii) no later than 10:00 a.m (New York time) three (3) Business  Days in advance
of the requested  conversion or  continuation  date, in the case of a conversion
into, or  continuation  of, LIBOR Loans.  The Notice of  Conversion/Continuation
shall specify (1) the conversion or continuation date (which shall be a Business
Day), (2) the amount and type of the Loans to be converted or continued, (3) the
nature of the  requested  conversion or  continuation,  and (4) in the case of a
conversion into, or continuation of, LIBOR Loans, the requested Interest Period.
Promptly after receipt of a Notice of  Conversion/Continuation  pursuant to this
Section  2.06(b),  the Agent  shall  notify  the  Revolving  Lenders or the Term
Lenders,  as  applicable,  by  telecopy,  telephone  or  other  similar  form of
transmission,  of the requested conversion or continuation.  In the event that a
Borrower should fail to provide a Notice of Conversion/Continuation with respect
to any LIBOR Loans as provided  above,  such Loans shall, on the last day of the
Interest Period with respect to such Loans, convert to Base Rate Loans.

          (c) Any  Notice  of  Conversion/Continuation  for  conversion  to,  or
continuation  of, Loans made pursuant to this Section 2.06 shall be  irrevocable
and the applicable  Borrower shall be bound to convert or continue in accordance
therewith.

          SECTION   2.07.    Special    Provisions    Governing   LIBOR   Loans.
Notwithstanding   any  other  provisions  to  the  contrary  contained  in  this
Agreement,  the following provisions shall govern with respect to LIBOR Loans as
to the matters covered:

          (a) Amount of LIBOR Loans. Each continuation of or conversion to LIBOR
Term  Loans,  and each  election  of,  continuation  of or  conversion  to LIBOR
Revolving  Loans,  shall be in a minimum  amount of  $5,000,000  and in integral
multiples of $1,000,000 in excess of that amount.


                                       26


          (b) Determination of Interest Period. By giving notice as set forth in
Section  2.06(b),  a  Borrower  shall  have the  option,  subject  to the  other
provisions of this Section 2.07, to specify whether the Interest Period for such
LIBOR Loan shall be a one, two, three or six month period.  The determination of
Interest Periods shall be subject to the following provisions:

               (i) In the case of immediately  successive Interest Periods, each
          successive  Interest  Period  shall  commence  on the day on which the
          preceding Interest Period expires.

               (ii) If any Interest Period would otherwise expire on a day which
          is not a Business Day, the Interest Period shall be extended to expire
          on the next succeeding  Business Day; provided,  however,  that if the
          next succeeding  Business Day occurs in the following  calendar month,
          then such Interest  Period shall expire on the  immediately  preceding
          Business Day.

               (iii) A Borrower may not select an Interest  Period for any LIBOR
          Loan,  which  Interest  Period expires later than the maturity date of
          such Loan.

               (iv) A Borrower may not select an Interest Period with respect to
          any  portion of such  Borrower's  Term Loans which  extends  beyond an
          installment  payment  date for such Term Loans  unless,  after  giving
          effect to such  selection,  the portion of such Term Loans not subject
          to Interest  Periods  ending  after such  installment  payment date is
          equal to or greater than the principal due on such installment payment
          date.

               (v) A Borrower may not select an Interest  Period with respect to
          any portion of such  Borrower's  Revolving  Loans which extends beyond
          any date on which the Revolving Loan Commitment  Amounts are scheduled
          to be reduced  unless,  after  giving  effect to such  selection,  the
          portion of the Revolving Loans not subject to Interest  Periods ending
          after  any such  date is equal to or  greater  than any  amount of the
          Revolving  Loans  required  to be  prepaid  as a  result  of any  such
          reduction.

               (vi) There  shall be no more than eight (8)  Interest  Periods in
          effect at any one time.


                                       27


          (c) Determination of Interest Rate. As soon as practicable after 10:00
a.m. (New York time) on the LIBOR  Interest Rate  Determination  Date, the Agent
shall  determine  (which   determination   shall,   absent  manifest  error,  be
presumptively  correct)  the  interest  rate for the  LIBOR  Loans  for which an
interest rate is then being  determined  and shall  promptly give notice thereof
(in writing or by telephone confirmed in writing) to the applicable Borrower. In
the event that on any LIBOR  Interest  Rate  Determination  Date the Agent shall
have  determined  (which   determination   shall,   absent  manifest  error,  be
presumptively correct and binding upon all parties) that:

               (i)  adequate  and fair means do not exist for  ascertaining  the
          applicable  interest  rates by  reference  to which the LIBO Rate then
          being determined is to be fixed; or

               (ii) the LIBO Rate plus the  Applicable  Margin for any  Interest
          Period  for such  Loans will not  adequately  reflect  the cost to any
          Lender of  making,  funding  or  maintaining  its LIBOR  Loan for such
          Interest  Period,  the Agent shall  forthwith so notify the applicable
          Borrower and the Lender, whereupon:

                    (A)  each LIBOR Loan will automatically,  on the last day of
                         the then existing  Interest  Period  therefor,  convert
                         into a Base Rate Loan; and

                    (B)  the  obligation  of the Lenders to make,  or to convert
                         Loans into,  LIBOR Loans shall be  suspended  until the
                         Agent  shall  notify the  applicable  Borrower  and the
                         Lenders that the circumstances  causing such suspension
                         no longer exist.

          (d) Illegality. Notwithstanding any other provision of this Agreement,
if any Lender shall notify the Agent that the  introduction  of or any change in
or in the  interpretation  of any law or  regulation  makes it unlawful,  or any
central bank or other  Governmental  Authority asserts that it is unlawful,  for
any Lender to perform its  obligations  hereunder to make LIBOR Loans or to fund
or maintain LIBOR Loans hereunder, (i) the obligation of the Lenders to make, or
to convert  Loans into or to continue  Loans as,  LIBOR Loans shall be suspended
until  the  Agent  shall  notify  the   Borrowers   and  the  Lenders  that  the
circumstances  causing such  suspension  no longer exist and (ii) the  Borrowers
shall on the termination of the Interest Period then applicable  thereto,  or on
such  earlier  date  required  by law,  prepay  in full  all  LIBOR  Loans  then
outstanding  together with accrued interest  thereon,  or convert all such LIBOR
Loans into Base Rate Loans in accordance with Section 2.06.

          (e)  Compensation.  In addition to such  amounts as are required to be
paid by the  Borrowers  pursuant to the other  Sections of this  Article II, the
Borrowers  agree  to  compensate  any  Lender  for  all  losses,   expenses  and
liabilities,  including,  without  limitation,  any loss or expense  incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by
such  Lender to fund or  maintain  such  Lender's  LIBOR  Loans  (including  the
Applicable  Margin  component  thereof) to the Borrowers,  which such Lender may
sustain  (i) if for any reason a funding of any LIBOR  Loans does not occur on a
date   specified   therefor   in  a   Notice   of   Borrowing   or   Notice   of
Conversion/Continuation, or a successive Interest Period does not commence after
notice  therefor  is given  pursuant  to Section  2.06 as a result of any act or
omission of any Borrower,  (ii) if any voluntary or mandatory  prepayment of any
LIBOR Loans occurs for any reason on a date which is not the last  scheduled day
of an Interest  Period,  (iii) as a  consequence  of any required  conversion of
LIBOR  Loans to Base Rate  Loans as a result of any of the events  indicated  in
Section 2.07(d),  or (iv) as a consequence of any other failure by a Borrower to
repay LIBOR Loans when required by the terms of this Agreement.


                                       28


          (f) Booking of LIBOR  Loans.  The Lenders may make,  carry or transfer
LIBOR  Loans at,  to, or for the  account  of,  any of their  respective  branch
offices or the office of any of their respective affiliates.

          (g) LIBOR Loans After Event of Default.  Unless the Requisite  Lenders
shall otherwise agree, after the occurrence of and during the continuance of any
Event of Default, the Borrowers may not borrow Revolving Loans as LIBOR Loans or
elect to have any Loans  continued  as, or  converted  to, LIBOR Loans after the
expiration of any Interest Period then in effect for such Loans.

          SECTION  2.08.  Payments.  (a)  Interest  on each  LIBOR Loan shall be
payable in arrears on each LIBOR  Interest  Payment Date and, if such LIBOR Loan
is paid in full other than on such LIBOR  Interest  Payment  date, on such other
date. Interest on each Base Rate Loan will be payable in arrears on each Payment
Date and,  if such Base Rate  Loan is paid in full  other  than on such  Payment
Date, on such other date.

          (b)  Subject  to  the  provisions  of  Sections  2.09  and  9.02,  the
outstanding  principal  balance of the Term Loans made to the Borrowers shall be
payable in twenty consecutive quarterly  installments of $187,500 each beginning
on the  fourteenth  Payment Date (i.e.  the Payment  Date  occurring on April 1,
2002) and continuing on each Payment Date  thereafter  through and including the
thirty-third  Payment Date (i.e.  the Payment Date occurring on January 1, 2007)
and two final  installments of $35,625,000 on April 1, 2007 and on the Term Loan
Termination  Date.  Subject to the  provisions  of Sections  2.09 and 9.02,  the
outstanding principal balance of the Revolving Loans made to the Borrowers shall
be payable on the Revolving Credit Commitment Termination Date.

          (c) Payments made with respect to the Loans by each Borrower  shall be
applied by the Agent first to unpaid and accrued  fees and  interest and then to
the  outstanding  unpaid  principal  balance  of the  Loans  of  such  Borrower;
provided,  however,  that upon the occurrence  and during the  continuance of an
Event of Default,  all payments and prepayments  with respect to the Obligations
and all proceeds of Collateral  shall be applied in the  following  order by the
Agent; provided,  further, that the order of priority set forth in the following
clauses may be altered upon direction from the Requisite Lenders to the Agent:

          (1) first,  to pay Obligations in respect of any expenses then due and
          payable by the  Borrowers  to the  Agents,  the  Lenders or any Person
          which is not a Lender that has issued a Letter of Credit;

          (2) second,  to pay  Obligations  in respect of any  reimbursement  or
          indemnities  then due and  payable to the  Agents,  the Lenders or any
          Person  which is not a  Lender  that has  issued  a Letter  of  Credit
          (excluding any  reimbursement  obligations with respect to any Letters
          of Credit);


                                       29


          (3) third,  to pay Obligations in respect of any fees due and owing to
          the Agent,  the  Collateral  Agent or any Person which is not a Lender
          that has issued a Letter of Credit;

          (4) fourth,  to pay  Obligations  in respect of the commitment fee and
          any other fees and commissions  then due and owing to the Agents,  the
          Lenders or any Person  which is not a Lender  that has issued a Letter
          of Credit;

          (5) fifth,  to pay  Obligations  in respect of any  accrued and unpaid
          interest due in respect of Loans and Letter of Credit Obligations;

          (6) sixth, to pay termination payments due and payable pursuant to any
          Interest Rate Agreement or hedging agreement;

          (7)  to  the  ratable  payment  or  prepayment  of  principal  of  any
          outstanding  Loans  and  reimbursement  obligations  with  respect  to
          Letters of Credit;

          (8) to provide  required  cash  collateral,  if  required  pursuant to
          Section 2.10(j); and

          (9) to the ratable payment of all other Obligations.

          SECTION 2.09. Optional and Mandatory Prepayment of Loans; Optional and
Mandatory  Reduction of Revolving Loan Commitment  Amount.  (a) Provided that no
Event of Default has occurred and is  continuing,  the Borrowers  shall have the
right upon the provision of sixty (60) days' prior written  notice to the Agent,
which notice, once given, shall be irrevocable, on any Payment Date with respect
to any Base  Rate  Term  Loans  and on the last day of the  applicable  Interest
Period with respect to any LIBOR Term Loans, to prepay the outstanding principal
of the Base Rate Term  Loans in a minimum  principal  amount of  $1,000,000  and
increments of $250,000 in excess thereof,  or the  outstanding  principal of the
LIBOR Term Loans in a minimum  principal  amount of $5,000,000 and increments of
$1,000,000  in excess  thereof,  multiple  thereof,  together  in each case with
accrued  interest  thereon  and  the  aggregate  Prepayment  Premium  applicable
thereto.  The amount of principal so prepaid  shall be applied to the  remaining
principal  payments of the type of Loans prepaid  (i.e.  Base Rate Term Loans or
LIBOR Term Loans) in the inverse order of maturity.

          (b) Upon the  occurrence  of any Event of Loss in excess of $1,000,000
with respect to any item of Collateral that is not repaired or replaced,  or any
Events of Loss which,  in the aggregate,  exceed  $5,000,000 with respect to any
item or items of  Collateral  that are not  repaired or replaced  (in each case,
other than an item of Collateral no longer used or useful in the Business)  such
that after such repair or replacement it has a value at least equal to its value
prior to the  occurrence of such Event of Loss, the Borrower which suffered such
Event of Loss shall make a principal  prepayment within thirty (30) days of such
Event  of Loss in an  amount  equal  to the  replacement  value  of the  item of
Collateral  which  suffered such Event of Loss,  together with accrued  interest
thereon (but without the Prepayment  Premium) with such principal  payment to be
applied,  pro rata, to outstanding  principal balance of the Revolving Loans and
the Term Loans.


                                       30


          (c) In the event that any  Borrower  finances  any  Telecommunications
Equipment  (exclusive  of soft costs that exceed  fifteen  percent  (15%) of the
invoiced  price of the related  Telecommunications  Equipment)  with a financing
source  other than a Loan  pursuant  to this  Agreement,  then  thirty (30) days
following  such  financing  the  Revolving  Loan  Commitment  Amounts of all the
Revolving  Lenders shall be reduced by the actual or imputed principal amount of
any such  financing,  and any prepayments of the Revolving Loans required by the
provisions of clause (h) below shall be accompanied by any applicable Prepayment
Premium thereon.

          (d) The Borrowers  shall prepay the Revolving Loans and the Term Loans
on a pro rata basis in a principal  amount  equal to (i) all of the net proceeds
of any sales of assets of any Borrower  other than sales in the ordinary  course
of business,  which  proceeds are not  reinvested  within 270 days after receipt
thereof in replacement assets, plus the applicable  Prepayment Premium, and (ii)
the proceeds of insurance  policies paid to any Borrower and not applied  within
270 days after any such  payment  to  replacing,  rebuilding  or  restoring  the
Collateral  which was the subject of  insurance  loss,  without  any  Prepayment
Premium,  in each  case,  within  five  (5) days  after  the  expiration  of the
applicable 270 day period.

          (e) On the first Payment Date of each year,  commencing  in 2002,  the
Revolving  Loan  Commitment  Amounts of all the  Lenders  shall be reduced by an
amount  equal to fifty  percent  (50%) of  Excess  Operating  Cash  Flow for the
preceding  fiscal year until the Borrowers  have achieved and  maintained for at
least two consecutive fiscal quarters,  a Total Leverage Ratio of less than 5:1,
as  determined by reference to the financial  statements  delivered  pursuant to
Section 5.06.

          (f) Provided that no Event of Default has occurred and is  continuing,
commencing  January  1,  2002,  the  Borrowers  shall  have the  right  upon the
provision of thirty days' prior written notice to the Agent, which notice,  once
given,  shall be irrevocable,  on any Payment Date, to reduce the Revolving Loan
Commitment Amount of all the Lenders.  Each such reduction shall be in a minimum
principal amount of $1,000,000 and increments of $250,000 in excess thereof. Any
Revolving  Loans that must be prepaid in connection  with such  reduction in the
Revolving  Loan  Commitment  Amount  pursuant  to  clause  (h)  below,  shall be
accompanied by any applicable Prepayment Premium thereon.

          (g) The Revolving Loan  Commitment  Amount of all the Lenders shall be
reduced on each  Payment  Date  beginning  April 1, 2002 as set forth on Annex C
hereto.  In addition,  in the event that at any time more than  fifteen  percent
(15.0%) of the average  outstanding  principal balance of Revolving Loans during
the immediately  preceding 90-day period is repaid and is not reborrowed  within
120 days after such repayment,  then on such date, the Revolving Loan Commitment
Amount of all the  Lenders  shall be reduced by an amount  equal to such  amount
that was not reborrowed.  Any Revolving Loans that must be prepaid in connection
with such reduction in the Revolving Loan Commitment  Amount pursuant to Section
2.09(h) below, shall be accompanied by any applicable Prepayment Premium.

          (h) On each date that the Revolving Loan Commitment Amount is reduced,
the Borrowers shall prepay first, the Revolving  Loans,  and second,  provide to
the Agent cash  collateral  with respect to the Letter of Credit  Obligations in
such  amounts  such that the sum of the  outstanding  principal  balance  of the


                                       31


Revolving  Loans  plus the  Letter of Credit  Obligations  does not  exceed  the
Revolving  Loan  Commitment  Amount of all the  Revolving  Lenders  after giving
effect to the  reduction  thereof  effective  on such  date,  together  with any
applicable  Prepayment  Premium  thereon.  Any reduction in the  Revolving  Loan
Commitment Amount of all the Lenders shall be allocated to each Revolving Lender
based on its Pro Rata Share.  All  prepayments of principal  shall be applied to
the  remaining  principal  payments of the type of Loans  prepaid in the inverse
order of  maturity.  The  Letter of Credit  Obligations  shall be  reduced  on a
dollar-for-dollar basis by the cash collateral.

          SECTION 2.10. Letters of Credit.

          (a) Agreement to Cause  Issuance.  Subject to the terms and conditions
of this Agreement,  and in reliance upon the  representations  and warranties of
the Borrowers  herein set forth, the Agent agrees to (1) cause Letters of Credit
to be issued by Lenders who are willing to do so or (2) provide  credit  support
or  enhancement  or  otherwise   confirm   payment  (any  such  credit  support,
enhancement or payment  confirmation  being referred to as "Credit  Support") to
banks other than Lenders,  which banks are acceptable to the Agent,  which issue
Letters of Credit for the  respective  accounts of the  Borrowers in  accordance
with this Section 2.10 from time to time during the term of this Agreement.

          (b) Amounts;  Outside  Expiration  Date.  The Agent shall not have any
obligation  to cause any Letter of Credit to be issued by a Lender or to provide
Credit Support for any Letter of Credit at any time if: (1) the maximum  undrawn
face amount of the Letter of Credit is greater than the Unused  Letter of Credit
Subfacility;  or (2) such  Letter of Credit  has an  expiration  date later than
thirty (30) days prior to the Revolving Credit  Commitment  Termination Date, or
more than one (1) year from the date of issuance.

          (c) Other Conditions. In addition to being subject to the satisfaction
of the applicable  conditions  precedent contained in Article IV, the obligation
of the  Agent to cause  any  Letter  of  Credit  to be  issued by a Lender or to
provide  Credit  Support  for any Letter of Credit is  subject to the  following
conditions  precedent  having been  satisfied  in a manner  satisfactory  to the
Agent:

               (1) the applicable  Borrower shall have delivered to the proposed
          issuer of such  Letter of Credit,  at such times and in such manner as
          such  proposed  issuer  may  prescribe,  an  application  in form  and
          substance satisfactory to such proposed issuer for the issuance of the
          Letter of Credit and such other documents as may be required  pursuant
          to the terms thereof, and the form and terms of the proposed Letter of
          Credit shall be  satisfactory  to the Agent and such proposed  issuer;
          and

               (2) as of the date of issuance, no order of any court, arbitrator
          or  Governmental  Authority  shall  purport  by its terms to enjoin or
          restrain money center banks  generally from issuing  letters of credit
          of the type and in the amount of the proposed Letter of Credit, and no


                                       32


          law, rule or regulation applicable to money center banks generally and
          no request or directive  (whether or not having the force of law) from
          any Governmental  Authority with  jurisdiction over money center banks
          generally shall prohibit,  or request that the proposed issuer of such
          Letter of Credit  refrain  from,  the  issuance  of  letters of credit
          generally or the issuance of such Letters of Credit.

          (d) Issuance of Letters of Credit.

               (1) Request for Letter of Credit.  The applicable  Borrower shall
          give  the  Agent  five  (5)  Business  Days'  prior  written   notice,
          containing  the original  signature of an  authorized  officer of such
          Borrower,  of such Borrower's  request for the issuance of a Letter of
          Credit or the provision of Credit Support for a Letter of Credit. Such
          notice shall be irrevocable and shall specify the original face amount
          of the Letter of Credit,  the  effective  date  (which date shall be a
          Business Day) of issuance of such proposed  Letter of Credit,  whether
          such  Letter of Credit may be drawn in a single or in  partial  draws,
          the date on which such  proposed  Letter of Credit is to expire (which
          date shall be a Business  Day),  the  purpose for which such Letter of
          Credit is to be issued,  and the beneficiary of such Letter of Credit.
          The  applicable  Borrower  shall attach to such notice the form of the
          proposed Letter of Credit.

               (2)  Responsibilities  of the Agent;  Issuance.  The Agent  shall
          determine,  as of the Business Day immediately preceding the requested
          effective  date of  issuance  of the Letter of Credit set forth in the
          notice from the applicable  Borrower  pursuant to Section  2.10(d)(1),
          the amount of the applicable Unused Letter of Credit  Subfacility.  If
          (A) the undrawn  face amount of the  proposed  Letter of Credit is not
          greater than the applicable Unused Letter of Credit  Subfacility,  and
          (B) the Agent has received a certificate  from such  Borrower  stating
          that the  applicable  conditions  set  forth in  Article  IV have been
          satisfied, the Agent shall cause such Letter of Credit to be issued on
          such proposed effective date of issuance.

               (3) Notice of Issuance. The Agent shall promptly give each Lender
          written notice of the issuance of each Letter of Credit.

               (4) No  Extensions  or  Amendment.  No Letter of Credit  shall be
          extended or amended unless the  requirements  of this Section  2.10(d)
          are met as though a new  Letter of Credit  were  being  requested  and
          issued.

          (e)  Payments Pursuant to Letters of Credit.

               (1) Payment of Letter of Credit Obligations.  The Borrowers agree
          to reimburse  the issuer for any draw under any Letter of Credit,  and
          the Agent,  for the account of the Lenders,  upon any payment pursuant
          to any Credit Support,  immediately upon demand, and to pay the issuer
          of the Letter of Credit the amount of all other  Obligations and other
          amounts  payable to such issuer under or in connection with any Letter
          of Credit  immediately when due,  irrespective of any claim,  set-off,
          defense or other right which a Borrower  may have at any time  against
          such issuer or any other Person.


                                       33


               (2) Revolving Loans to Satisfy Reimbursement Obligations.  In the
          event that the issuer of any Letter of Credit honors a draw under such
          Letter of Credit, or the Agent shall have made any payment pursuant to
          any Credit  Support,  and the  Borrowers  shall not have  repaid  such
          amount to the  issuer  of such  Letter  of  Credit  or the  Agent,  as
          applicable,  pursuant to Section  2.10(e)(1),  the Agent  shall,  upon
          receiving notice of such failure, notify each Revolving Lender of such
          failure,  and each Revolving Lender shall  unconditionally  pay to the
          Agent, for the account of such issuer or the Agent, as applicable,  as
          and when  provided  hereinbelow,  an  amount  equal to such  Revolving
          Lender's  Pro Rata Share of the amount of such  payment in Dollars and
          in same day funds.  If the Agent so  notifies  the  Revolving  Lenders
          prior  to  12:00  p.m.  (New  York  time) on any  Business  Day,  each
          Revolving  Lender shall make available to the Agent the amount of such
          payment, as provided in the immediately  preceding  sentence,  on such
          Business Day. Such amounts paid by the Revolving  Lenders to the Agent
          shall  constitute  Revolving  Loans which shall be deemed to have been
          requested by the applicable Borrower pursuant to Section 2.03.

          (f)  Participations.

               (1) Purchase of Participations.  Immediately upon issuance of any
          Letter of Credit in accordance  with Section  2.10(d),  each Revolving
          Lender  shall  be  deemed  to  have  irrevocably  and  unconditionally
          purchased  and received  without  recourse or  warranty,  an undivided
          interest  and  participation  in such Letter of Credit (if issued by a
          Revolving  Lender) or the Credit Support provided through the Agent to
          such issuer in connection  with the issuance of such Letter of Credit,
          as applicable,  equal to such Revolving Lender's Pro Rata Share of the
          face  amount of such  Letter of  Credit or the  amount of such  Credit
          Support  (including,   without  limitation,  all  obligations  of  the
          Borrowers with respect thereto,  and any security therefor or guaranty
          pertaining thereto).

               (2) Sharing of Reimbursement  Obligation  Payments.  Whenever the
          Agent  receives a payment from a Borrower on account of  reimbursement
          obligations  in respect of a Letter of Credit or Credit  Support as to
          which the Agent has previously  received for the account of the issuer
          thereof  payment  from a Revolving  Lender  pursuant  to this  Section
          2.10(f)(2), the Agent shall promptly pay to such Lender such Revolving
          Lender's Pro Rata Share of such payment from such Borrower in Dollars.
          Each such  payment  shall be made by the Agent on the  Business Day on
          which the Agent  receives  immediately  available  funds  paid to such
          Person pursuant to the  immediately  preceding  sentence,  if received
          prior to 11:00 a.m. (New York time) on such Business Day and otherwise
          on the next succeeding Business Day.

               (3) Documentation.  Upon the request of any Revolving Lender, the
          Agent shall furnish to such  Revolving  Lender copies of any Letter of
          Credit,  reimbursement  agreement  executed in  connection  therewith,
          application  for any  Letter of Credit  and  Credit  Support  provided
          through  the Agent in  connection  with the  issuance of any Letter of
          Credit, and such other documentation as may reasonably be requested by
          such Revolving Lender.


                                       34


               (4)  Obligations  Irrevocable.  The obligations of each Revolving
          Lender to make  payments  to the Agent  with  respect to any Letter of
          Credit or with  respect to any Credit  Support  provided  through  the
          Agent with respect to a Letter of Credit,  and the  obligations of the
          Borrowers  to make  payments  to the  Agent,  for the  account  of the
          Revolving   Lenders,   shall  be  irrevocable,   not  subject  to  any
          qualification or exception  whatsoever and shall be made in accordance
          with the terms and conditions of this Agreement (assuming, in the case
          of the  obligations  of the Revolving  Lenders to make such  payments,
          that the Agent has provided  Credit  Support for such Letter of Credit
          in accordance with the terms of Section 2.10(d)),  including,  without
          limitation, any of the following circumstances:

                    (i) any lack of validity or enforceability of this Agreement
               or any of the other Loan Documents;

                    (ii) the existence of any claim,  set-off,  defense or other
               right which a Borrower may have at any time against a beneficiary
               named in a Letter of Credit or any  transferee  of any  Letter of
               Credit  (or any  Person  for  whom  any  such  transferee  may be
               acting),  any Lender, the Agent, the Collateral Agent, the issuer
               of such  Letter  of  Credit,  or any  other  Person,  whether  in
               connection  with  this  Agreement,  any  Letter  of  Credit,  the
               transactions  contemplated  herein or any unrelated  transactions
               (including any underlying  transactions between a Borrower or any
               other Person and the beneficiary named in any Letter of Credit);

                    (iii) any draft, certificate or any other document presented
               under the  Letter of Credit  proving  to be  forged,  fraudulent,
               invalid or insufficient  in any respect or any statement  therein
               being untrue or inaccurate in any respect;

                    (iv) the  surrender  or  impairment  of any security for the
               performance  or observance of any of the terms of any of the Loan
               Documents; or

                    (v) the occurrence of any Default or Event of Default.

          (g) Recovery or Avoidance of Payments.  In the event any payment by or
on behalf of a Borrower received by the Agent with respect to a Letter of Credit
or Credit  Support  provided  for any  Letter of Credit  (or any  guaranty  by a
Borrower  or  reimbursement  obligation  of a  Borrower  relating  thereto)  and
distributed by the Agent to the Revolving Lenders on account of their respective
participations  therein, is thereafter set aside,  avoided or recovered from the
Agent in connection with any receivership, liquidation or bankruptcy proceeding,
the Revolving  Lenders shall,  upon demand by the Agent,  pay to the Agent their
respective  Pro Rata  Shares of such  amount  set aside,  avoided or  recovered,
together  with  interest  at the rate  required to be paid by the Agent upon the
amount required to be repaid by it.

          (h) Compensation for Letters of Credit.

              The Borrowers agree to pay the fees set forth in Section 2.11 with
              respect to any Letters of Credit.


                                       35


          (i) Indemnification; Exoneration.

               (1) Indemnification.  In addition to amounts payable as elsewhere
          provided in this Section 2.10, the Borrowers  hereby agree to protect,
          indemnify,  pay and save the Lenders and the Agent  harmless  from and
          against any and all claims,  demands,  liabilities,  damages,  losses,
          costs,  charges and expenses  (including  reasonable  attorneys' fees)
          which  any  Lender  or the  Agent  may  incur  or be  subject  to as a
          consequence,  direct or  indirect,  of the  issuance  of any Letter of
          Credit or the provision of any Credit Support in connection therewith.
          The agreements  contained in this Section 2.10(i)(1) shall survive the
          payment in full of the Obligations.

               (2) Assumption of Risk by the Borrowers.  As among the Borrowers,
          the Lenders and the Agent, each Borrower assumes all risks of the acts
          and  omissions  of, or misuse of any of the  Letters of Credit by, the
          respective beneficiaries of such Letters of Credit. In furtherance and
          not in  limitation of the  foregoing,  the Lenders and the Agent shall
          not be responsible for: (A) the form, validity, sufficiency, accuracy,
          genuineness or legal effect of any document submitted by any Person in
          connection with the  application for and issuance of and  presentation
          of drafts  with  respect to any of the  Letters of Credit,  even if it
          should  prove  to be in  any or all  respects  invalid,  insufficient,
          inaccurate,  fraudulent or forged;  (B) the validity or sufficiency of
          any instrument  transferring or assigning or purporting to transfer or
          assign any Letter of Credit or the rights or  benefits  thereunder  or
          proceeds  thereof,  in whole or in part, which may prove to be invalid
          or ineffective  for any reason;  (C) the failure of the beneficiary of
          any Letter of Credit to comply duly with conditions  required in order
          to  draw  upon  such  Letter  of  Credit;   (D)   errors,   omissions,
          interruptions  or delays in  transmission or delivery of any messages,
          by mail, cable, telegraph, telex or otherwise,  whether or not they be
          in cipher;  (E) errors in  interpretation  of technical terms; (F) any
          loss  or  delay  in the  transmission  or  otherwise  of any  document
          required in order make a drawing  under any Letter of Credit or of the
          proceeds  thereof;  (G) the  misapplication  by the beneficiary of any
          Letter of Credit of the  proceeds of any drawing  under such Letter of
          Credit; or (H) any consequences arising from causes beyond the control
          of the Lenders or the Agent, including, without limitation, any act or
          omission,  whether  rightful or wrongful,  of any present or future de
          jure or de facto Governmental  Authority.  None of the foregoing shall
          affect,  impair or prevent  the vesting of any rights or powers of the
          Agent or any Lender under this Section 2.10(i).

               (3)  Exoneration.  In  furtherance  and  extension,  and  not  in
          limitation,  of the specific  provisions  set forth above,  any action
          taken or  omitted by the Agent or any  Lender  under or in  connection
          with any of the  Letters  of Credit or any  related  certificates,  if
          taken or omitted in good faith,  shall not put the Agent or any Lender
          under any resulting  liability to any Borrower or relieve any Borrower
          of any of its obligations hereunder to any such Person.


                                       36


          (j) Supporting Letter of Credit; Cash Collateral.  If, notwithstanding
the provisions of Section 2.10(b),  any Letter of Credit is outstanding upon the
termination of this  Agreement,  then upon such  termination the Borrowers shall
cause the termination of such Letter of Credit. If, at the Agent's election, any
such Letter of Credit remains outstanding, then the Borrowers shall deposit with
the Agent, for the ratable benefit of the Agent and the Revolving Lenders,  with
respect to each Letter of Credit then  outstanding,  as the Agent shall specify,
either (A) a standby letter of credit (a "Supporting  Letter of Credit") in form
and  substance  satisfactory  to the Required  Revolving  Lenders,  issued by an
issuer  satisfactory  to the Agent in an amount equal to the greatest amount for
which such Letter of Credit may be drawn, plus any fees and expenses  associated
with such Letter of Credit, under which Supporting Letter of Credit the Agent is
entitled to draw  amounts  necessary to  reimburse  the Agent and the  Revolving
Lenders for  payments  made by the Agent and the  Revolving  Lenders  under such
Letter of Credit or under any Credit  Support  provided  through  the Agent with
respect thereto and any fees and expenses associated with such Letter of Credit,
or (B) cash in  amounts  necessary  to  reimburse  the Agent  and the  Revolving
Lenders  for  payments  made by the Agent or the  Revolving  Lenders  under such
Letter of Credit or under any Credit  Support  provided  through  the Agent with
respect  thereto,  and any fees and  expenses  associated  with  such  Letter of
Credit. Such Supporting Letter of Credit or deposit of cash shall be held by the
Agent,  for the  ratable  benefit  of the Agent and the  Revolving  Lenders,  as
security  for,  and to provide for the payment of, the  aggregate  undrawn  face
amount of such Letters of Credit remaining outstanding.

          SECTION  2.11.  Fees.  (a) The  Borrowers  shall pay and the Borrowers
shall be  jointly  and  severally  liable to the Agent  for the  account  of the
Revolving Lenders for payment of a nonutilization  fee calculated on a per annum
basis and equal to the percentage  corresponding to the criteria set forth below
of the average of the unused Revolving Loan Commitment  Amount for the quarterly
period preceding a Payment Date, which fee shall be payable on each Payment Date
following such last day of a quarter beginning on the Payment Date following the
Initial  Funding  Date  until and  including  the  Payment  Date  following  the
Revolving Credit Commitment Termination Date:

                Drawn Portion of
         Revolving Loan Commitment
                 Amount as of the
         Last Day of each Quarter Preceding
                 a Payment Date                                       Percentage
         ----------------------------------                           ----------
         Less than or equal to
         $58,333,333                                                   1.25%

         Greater than $58,333,333 and
         less than or equal to $116,666,666                            1.00%

         Greater than $116,666,666 and
         less than or equal to $175,000,000                            0.75%


                                       37


In the event that at any time the Borrowers fail to comply with the requirements
of  Section  2.03(d)  for  any  calendar  year,  each  of  the  above  described
nonutilization  fees shall be  increased by 100 basis points for the entire such
calender year with payment of such increment in the nonutilization fee being due
and payable not later than the last Business Day of such calendar year.

          (b) The  Borrowers  shall pay the Agent and the  Collateral  Agent and
shall be jointly and  severally  liable to the Agent and the  Collateral  Agent,
respectively,  for  payment  of an annual  administration  fee and a  collateral
monitoring fee at the times and in the amounts set forth in the Fee Letters.

          (c)  The  Borrowers  shall  on the  Closing  Date  pay the  Agent  the
underwriting fee and the structuring fee referred to in the Fee Letters.

          (d) The  Borrowers  shall pay and the  Borrowers  shall be jointly and
severally  liable to the Agent (i) for the account of the Revolving  Lenders for
payment in arrears on each  Payment  Date of a fee equal to equal to the product
of the Applicable Margin in effect with respect to LIBOR Loans for the preceding
calendar  quarter on an annualized  basis,  multiplied by the average  Letter of
Credit Obligations  outstanding  during such calendar quarter,  and (ii) for the
account of any Person which issues any Letter of Credit,  for payment in arrears
on each  Payment  Date of a fee equal to (A) the product of  one-eighth  percent
(0.125%)  per annum  multiplied  by the average face amount of Letters of Credit
issued by such Person and outstanding during the preceding calendar quarter, and
(B) if such  Person is not a Lender,  any  additional  fees as may be charged by
such Person in  connection  with the issuance or  maintenance  of such Letter of
Credit.

          (e) All fees once paid shall be nonrefundable.

          SECTION 2.12. Manner of Payment;  Special Tax Considerations.  (a) All
payments  by the  Borrowers  hereunder  and under the Notes shall be made to the
Agent by wire transfer or other electronic payment method to the Payment Account
or to such bank  account  as the Agent may  designate,  for the  account  of the
Lenders in Dollars in immediately  available funds by 11:00 a.m., New York time,
on the  date on which  such  payment  shall  be due.  The  Agent  will  promptly
thereafter  cause to be  distributed  like  funds  relating  to the  payment  of
principal or interest or other fees ratably (other than amounts payable pursuant
to  Section  2.14) to each  Lender in  accordance  with  Section  10.07  hereof.
Interest in respect of any Loan hereunder shall accrue from the day such Loan is
made up to and including the day prior to the date on which such Loan is paid in
full.  Payments  received  after 12:00 p.m.  shall not be given credit until the
next  Business  Day, and the  Borrowers  shall be liable for  interest,  if any,
accruing on such payment until the next Business Day.

          (b) (1) Any and all payments by each Borrower  hereunder shall be made
free and clear of and without  deduction for any and all Taxes.  If any Borrower
shall be  required  by law to deduct  any Taxes  from or in  respect  of any sum
payable  hereunder or under the other Loan Documents to any Lender or Agent, (A)
the sum payable  shall be increased as may be necessary so that after making all
required deductions  (including deductions applicable to additional sums payable


                                       38


under this  Section  2.12) such Lender or Agent  receives an amount equal to the
sum it would have received had no such  deductions  been made, (B) such Borrower
shall make such  deductions,  and (C) such  Borrower  shall pay the full  amount
deducted to the relevant  taxation  authority or other  authority in  accordance
with applicable law. If a withholding tax of the United States of America or any
other Governmental Authority shall be or become applicable (y) after the date of
this  Agreement,  to the payments by any Borrower made to the Lending  Office or
any other  office  that a Lender may claim as its Lending  Office,  or (z) after
such Lender's  selection and  designation of any other Lending  Office,  to such
payments made to such other  Lending  Office,  such Lender shall use  reasonable
efforts to make,  fund and maintain its Loans through  another Lending Office of
such  Lender in another  jurisdiction  so as to reduce,  but not  increase,  the
applicable Borrower's liability hereunder, if the making, funding or maintenance
of such Loans through such other Lending  Office of such Lender does not, in the
judgment of such Lender,  otherwise materially adversely affect such Loans, such
Lender's  obligations  under  its  Commitment  or such  Lender.  Notwithstanding
anything to the  contrary  hereunder,  if a Person  becomes a Lender  under this
Agreement  pursuant to Section 11.08 hereof,  the Borrowers shall in no event be
required to increase any payment  pursuant to paragraph (b) of this Section 2.12
by an amount that would exceed the amount of any increase that would be required
to be made under paragraph (b) of this Section 2.12 to the assigning Lender.

          (2) The Borrowers will jointly and severally indemnify each Lender and
the  Agents  and hold them  harmless  for the full  amount of Taxes  (including,
without limitation,  any Taxes imposed by any Governmental  Authority on amounts
payable under this Section 2.12 or any other documentary  taxes,  assessments or
charges  made by any  Governmental  Authority  by  reason of the  execution  and
delivery of this  Agreement or any other Loan  Document)  paid by such Lender or
the Agent (as the case may be) and any liability (including penalties, interest,
and expenses)  arising therefrom or with respect thereto.  This  indemnification
shall be made  within  thirty  (30) days after the date such Lender or the Agent
(as the case may be) makes written  demand  therefor.  A  certificate  as to any
additional  amount  payable to any Lender or the Agent under this  Section  2.12
submitted to the Borrowers and the Agent (if a Lender is so  submitting) by such
Lender or the Agent shall show in reasonable  detail the amount  payable and the
calculations  used to determine  such amount.  With respect to such deduction or
withholding  for or on account  of any Taxes and to confirm  that all such Taxes
have been  paid to the  appropriate  Governmental  Authorities,  the  applicable
Borrower  shall promptly (and in any event not later than thirty (30) days after
receipt)  furnish to each Lender and the Agent such  certificates,  receipts and
other documents as may be required (in the judgment of such Lender or the Agent)
to establish any tax credit to which such Lender or the Agent may be entitled.

          (3) Within  thirty (30) days after the date of any payment of Taxes on
amounts  payable  hereunder by any  Borrower,  such Borrower will furnish to the
Agent, at its address  referred to in Section 11.01, the original or a certified
copy of a receipt evidencing payment thereof.

          (4) Without  prejudice to the  survival of any other  agreement of any
Borrower hereunder, the agreements and obligations of such Borrower contained in
this  Section 2.12 shall  survive the payment in full of principal  and interest
hereunder and the termination of this Agreement.


                                       39


          (5) Without  limiting  the  obligations  of the  Borrowers  under this
Section 2.12, each Lender that is not created or organized under the laws of the
United States of America or a political subdivision thereof shall deliver to the
Borrowers  and the Agent on or before the effective  date hereof,  or, if later,
the date on which such Lender becomes a Lender pursuant to Section 11.08 hereof,
a true and  accurate  certificate  executed in  duplicate  by a duly  authorized
officer of such Lender,  in a form  satisfactory to the Borrowers and the Agent,
to the effect that such Lender is capable under the  provisions of an applicable
tax  treaty  concluded  by the  United  States of  America  (in  which  case the
certificate  shall be accompanied by two original,  executed copies of Form 1001
of the IRS) or under  Section  1442 of the IRC (in  which  case the  certificate
shall be accompanied by two original,  executed  copies of Form 4224 of the IRS)
of  receiving  payments  of  interest  hereunder  exempt  from  or at a  reduced
deduction or withholding of United States federal income tax or that such Lender
is not a bank  described in Section  881(c)(3)(A)  of the IRC (in which case the
certificate  should be accompanied by two original,  executed copies of Form W-8
or W-9 of the IRC).  Each such Lender further agrees to deliver to the Borrowers
and the Agent  from time to time a true and  accurate  certificate  executed  in
duplicate by a duly authorized  officer of such Lender  substantially  in a form
satisfactory  to the  Borrowers  and the  Agent,  before  or  promptly  upon the
occurrence  of any  event  requiring  a change  in the most  recent  certificate
previously  delivered  by it to the  Borrowers  and the Agent  pursuant  to this
Section   2.12(b)(5).   Further,   each  Lender  which  delivers  a  certificate
accompanied  by Form 1001 of the IRS  covenants  and  agrees to  deliver  to the
Borrowers and the Agent within  fifteen (15) days prior to January 1, 1999,  and
every third  anniversary  of such date  thereafter,  on which this  Agreement is
still in effect, another such certificate and two accurate and complete original
signed copies of Form 1001 (or any successor  form or forms  required  under the
IRC or the applicable regulations promulgated thereunder),  and each Lender that
delivers a certificate  accompanied by Form 4224 of the IRS covenants and agrees
to deliver to the Borrowers and the Agent within  fifteen (15) days prior to the
beginning  of each  subsequent  taxable  year of such Lender  during  which this
Agreement  is still in effect,  another  such  certificate  and two accurate and
complete original signed copies of IRS Form 4224 (or any successor form or forms
required under the IRC or the applicable  regulations  promulgated  thereunder).
Each such certificate shall certify as to one of the following:

               (a) that such Lender is capable of receiving payments of interest
          hereunder  exempt from or at a reduced  deduction  or  withholding  of
          United States of America federal income tax;

               (b) that such  Lender is not  capable of  receiving  payments  of
          interest   hereunder  exempt  from  or  at  a  reduced   deduction  or
          withholding  of  United  States  of  America  federal  income  tax  as
          specified  therein but is capable of recovering the full amount of any
          such deduction or  withholding  from a source other than the Borrowers
          and will not seek any such recovery from the Borrowers; or


                                       40


               (c) that,  as a result of the  adoption  of or any  change in any
          law,  treaty,  rule,  regulation,  guideline  or  determination  of  a
          Governmental   Authority  or  any  change  in  the  interpretation  or
          application  thereof by a Governmental  Authority  after the date such
          Lender became a party hereto,  such Lender is not capable of receiving
          payments of interest  hereunder  without  deduction or  withholding of
          United States of America  federal income tax as specified  therein and
          that it is not capable of recovering  the full amount of the same from
          a source other than the Borrowers.

          Each Lender shall promptly furnish to the Borrowers and the Agent such
additional documents as may be reasonably required by the Borrowers or the Agent
to  establish  any  exemption  from or  reduction  of any Taxes  required  to be
deducted or withheld  and which may be obtained  without  undue  expense to such
Lender

          (6) For a period with  respect to which a Lender has failed to provide
the Agent and the Borrowers with the appropriate  form described in this Section
2.12(b)(5)  (other  than if 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 Lender  shall not be entitled to  indemnification  under this  Section 2.12
with respect to Taxes  imposed by the United  States by reason of such  failure;
provided,  however,  that should a Lender become subject to Taxes because of its
failure to deliver a form  required  hereunder,  the  Borrowers  shall take such
steps as such Lender shall  reasonably  request to assist such Lender to recover
such Taxes.

          (c)(1) If a Borrower  pays any  additional  amount  under this Section
2.12 and, as a result,  any Lender,  together with the Agent,  subsequently,  in
their sole discretion and based on their own interpretation of any relevant laws
(but  acting in good faith)  receive or are  granted a final and  non-appealable
credit  against  or  deduction  from or in  respect  of any tax  payable by such
Lender,  or obtain any other final and  non-appealable  relief in respect of any
tax, which in the opinion of such Lender and the Agent, acting in good faith, is
both reasonably  identifiable  and  quantifiable  by them without  requiring any
Lender, the Agent or their professional  advisers to expend a material amount of
time or incur a  material  cost in so  identifying  or  quantifying  (any of the
foregoing,  to the extent so reasonably  identifiable  and  quantifiable,  being
referred to as a "Saving"),  such Lender shall,  to the extent that it can do so
without  prejudice  to the  retention  of the Saving,  reimburse  such  Borrower
promptly after such  identification and  quantification  with the amount of such
Saving;  provided,  however,  that any such Saving shall be reduced by any costs
incurred by such Lender or the Agent in obtaining such Saving.

          (2)  Nothing  in this  Section  2.12(c)  shall  require  any Lender to
disclose to any Person any  information  regarding its tax affairs or to arrange
its tax and other affairs in any particular manner.

          SECTION  2.13.  Maximum  Lawful  Interest  Rate.  Notwithstanding  any
provision  contained herein, the total liability of the Borrowers for payment of
interest  pursuant  hereto and the Notes,  including  any other charges or other
amounts, to the extent such charges and other amounts are deemed to be interest,
shall not exceed the  maximum  amount of such  interest  permitted  by law to be
charged,  collected, or received from the Borrowers (the "Maximum Rate"). If any
payments  by any  Borrower  for the  account of any Lender  include  interest in
excess of the Maximum Rate, such Lender shall apply such excess to the reduction
of the unpaid principal  amount owing by such Borrower,  or if none is due, such
excess shall be returned to such Borrower.


                                       41



          SECTION 2.14.  Funding Issues.  (a) Increased Costs. If, due to either
(i) the  introduction  after the date  hereof of, or any  change  after the date
hereof in or in the interpretation of, any applicable law, rule or regulation by
any Governmental  Authority,  central bank or comparable agency charged with the
interpretation or administration  thereof or (ii) compliance by any Lender after
the date hereof with any final request or final directive  issued after the date
hereof  (whether  or not  having  the  force  of law) by any  such  Governmental
Authority,  central bank or  comparable  agency,  and, as a result of any of the
events  set forth in the above  clauses  (i) and  (ii),  (x) there  shall be any
increase in the cost to such Lender in  maintaining  its  Commitment  under this
Agreement or funding or  maintaining  its Pro Rata Share of the Loans under this
Agreement,  or (y) any Lender is subjected to any charge or  withholding  on its
obligations  hereunder,  or changes in the basis of  taxation of payments to any
Lender in connection  with any of the foregoing  (except for changes in the rate
of tax on overall net income of any Lender)  (collectively,  "Increased Costs"),
then the Borrowers  shall,  from time to time, pay, to the Agent for the benefit
of such Lender  within 15 days after such Lender shall have  provided  notice to
the Agent (and the Agent shall have  provided  notice to the  Borrowers) of such
Increased  Cost,  an  amount  sufficient  to  compensate  such  Lender  for such
Increased Cost, as provided  herein.  A certificate  setting forth in reasonable
detail the  computation of the amount of such Increased Cost (which  increase in
cost shall be determined by such Lender's reasonable allocation of the aggregate
of such cost increases resulting from such event), submitted to the Borrowers by
such Lender,  shall be conclusive and binding for all purposes,  absent manifest
error.

          (b)  Increased  Capital.  If any  Lender  which is  subject to minimum
capital  requirements  determines  that  compliance  by such  Lender,  with  any
guideline  or request  from any  central  bank or other  Governmental  Authority
(whether or not having the force of law)  affects or would  affect the amount of
capital required or expected to be maintained by such Lender, or any corporation
controlling such Lender,  and such Lender reasonably  determines that the amount
of such capital is increased by or based upon any  commitment to lend  hereunder
or making or maintaining  Loans,  its commitment to participate (as provided for
in  Section  2.10(f))  in any Letter of Credit or any  Credit  Support  provided
through the Agent in  connection  with the issuance of any Letter of Credit,  or
other commitments of this type, then, upon demand by such Person,  the Borrowers
agree to, within five (5) days of such demand, pay to such Person,  from time to
time as specified by such Person,  additional  amounts  sufficient to compensate
such Person in the light of such  circumstances,  to the extent that such Person
reasonably  determines such increase in capital to be allocable to such Person's
commitment or  maintenance  of Loans  hereunder or such  Person's  commitment to
participate in any Letter of Credit or Credit  Support.  A certificate as to the
amount of such  increased  cost,  submitted to the  Borrowers by the  applicable
Person shall,  absent manifest error, be conclusive and binding on the Borrowers
for all purposes.


                                       42


          (c)  Replacement  of  Lender.  If any  Borrower,  as a  result  of the
requirements of either Section 2.14(a) or Section 2.14(b),  shall be required to
pay any particular Lender (an "Affected Lender") the additional amounts referred
to in such Section,  which costs are not imposed by the other Lenders,  and such
additional amounts are material,  then such Borrower shall be entitled to find a
replacement Lender,  reasonably acceptable to the Agents (the Agents' consent to
such  replacement  Lender  not to be  unreasonably  withheld),  to  replace  the
Affected Lender. The Affected Lender and the replacement Lender shall execute an
Assignment  Agreement with respect to all of the Affected  Lender's  Commitments
and all Loans owing to the Affected Lender and comply with the other  provisions
of Section 11.08(c).  Upon the payment by the replacement Lender to the Affected
Lender of the then  outstanding  principal amount of Loans owing to the Affected
Lender,  together with accrued interest thereon, and the payment by the Borrower
to the Affected Lender of any compensation  required with respect to LIBOR Loans
pursuant to Section 2.07(e),  the replacement Lender shall succeed to all of the
Affected Lender's rights and obligations under this Agreement and the other Loan
Documents.

          SECTION  2.15.  Joint  and  Several   Liability;   Contribution.   (a)
Notwithstanding  anything to the  contrary in this  Agreement  or the other Loan
Documents,  all payment and performance Obligations arising under this Agreement
and the other Loan  Documents  shall be joint and  several  obligations  of each
Borrower secured by all the Borrowers' Collateral.  The Agent and the Collateral
Agent may apply any portion of any  Borrower's  Collateral to satisfy any of the
Obligations of any other Borrower.

          (b) Contribution  and  Indemnification  between the Borrowers.  To the
extent that any Borrower  shall,  as a result of the  operation of Section 2.15,
pay any Obligation of any other Borrower under the Loan Documents  (such payment
being referred to as an  "Accommodation  Payment"),  then such Borrower shall be
entitled to  contribution  and  indemnification  from, and be reimbursed by such
other Borrower, as set forth in the Contribution Agreement. Each Borrower agrees
that any extension,  forbearance  or amendment,  or any  acceptance,  release or
substitution of security,  or any impairment or suspension of Lender's  remedies
or rights  against any other  Borrower or the  cessation of the liability of any
other Borrower for any reason other than full and  indefeasible  satisfaction of
all Obligations shall not in any way affect the liability of such Borrower. Each
Borrower has provided itself of the means of remaining informed of the financial
condition of each other Borrower, and waives any right to require Lender to keep
it informed of the financial condition of any other Borrower.  The provisions of
this section shall, to the extent expressly  inconsistent  with any provision in
any Loan Document, supersede such inconsistent provision.


                                       43


                                   ARTICLE III

which there is a reasonable  possibility of an adverse  determination and which,
if adversely  determined,  would  individually  or in the  aggregate  materially
impair the right of any Borrower to carry on business substantially as now being
conducted or as presently  contemplated or would result in any Material  Adverse
Effect.

          SECTION  3.06.  Tax Returns.  Such  Borrower has filed or caused to be

contemplated in the Milestone Plan,  other than  immaterial  municipal  business

                                       45



permits.  Such  Governmental  Approvals and  approvals  are correctly  listed on
Schedule  3.09(a)  and  constitute  the  only  material  licenses,   permits  or
franchises  or  other  Governmental  Approvals  of  any  Governmental  Authority
required  in  connection  with  the  Systems  as are  presently  operating.  All
Governmental  Approvals of such Borrower are in full force and effect,  are duly

Such Borrower has given true and complete  copies of all such  agreements to the

Property, as requested by the Collateral Agent.

          SECTION 3.10.  Compliance  With Laws.  Except as disclosed on Schedule

Laws.  Except as  disclosed on Schedule  3.10,  none of the  operations  of such
Borrower is subject to any judicial or  administrative  proceeding  alleging the
violation of any Environmental  Laws. Except as disclosed on Schedule 3.10, such
Borrower neither knows nor reasonably  should know that any of the operations of
such  Borrower  is the  subject  of federal  or state  investigation  evaluating
whether  any  Remedial  Action is  needed to  respond  to a  Release.  Except as
disclosed  on Schedule  3.10,  such  Borrower has not filed any notice under any
federal or state law indicating past or present  treatment,  storage or disposal
of a hazardous  waste or  reporting a Release.  Except as  disclosed on Schedule
3.10,  such  Borrower has no  contingent  liability  of which such  Borrower has
knowledge or reasonably should have knowledge in connection with any Release.

          SECTION 3.11.  ERISA.  None of such Borrower or any ERISA Affiliate of
such Borrower  maintains or  contributes to any Plan other than a Plan listed on
Schedule 3.11 hereto.  Each Plan which is intended to be qualified under Section
401(a) of the IRC has been  determined by the IRS to be so  qualified,  and each
trust  related to any such Plan has been  determined  to be exempt from  federal
income tax under  Section  501(a) of the IRC.  Except as  disclosed  on Schedule
3.11, none of such Borrower or any ERISA  Affiliate  maintains or contributes to
any  employee  welfare  benefit plan within the meaning of Section 3(1) of ERISA


                                       46


which provides  benefits to employees after termination of employment other than
as  required  by  Section  601 of  ERISA.  None of such  Borrower  or any  ERISA
Affiliate  has  breached  any of the  responsibilities,  obligations  or  duties
imposed on it by ERISA or regulations promulgated thereunder with respect to any
Plan  which  breach  could  result in a  Material  Adverse  Effect.  No Plan has
incurred any accumulated  funding deficiency (as defined in Section 302(a)(2) of
ERISA and Section 412(a) of the IRC), whether waived or not waived. None of such
Borrower or any ERISA  Affiliate  nor any  fiduciary  of any Plan which is not a
Multiemployer  Plan (i) has  engaged  in a  nonexempt  "prohibited  transaction"
described  in Section 406 of ERISA or Section  4975 of the IRC or (ii) has taken
or failed to take any action which would  constitute  or result in a Termination
Event.  None of such Borrower or any ERISA  Affiliate has incurred any liability
to the PBGC  which  remains  outstanding  and which  could  result in a Material
Adverse  Effect,  other than the payment of  premiums,  and there are no premium
payments  which have become due which are unpaid.  Schedule B to the most recent
annual  report  filed  with the IRS with  respect to each Plan is  complete  and
accurate.  Since the date of each such  Schedule  B,  there has been no  adverse
change in the funding status or financial condition of the Plan relating to such
Schedule B. None of such Borrower or any ERISA  Affiliate has (i) failed to make
a  required  contribution  or  payment  to a  Multiemployer  Plan or (ii) made a
complete  or  partial  withdrawal  under  Sections  4203 or 4205 of ERISA from a
Multiemployer  Plan.  None of such Borrower or any ERISA Affiliate has failed to
make a required  installment or any other required  payment under Section 412 of
the IRC on or before the due date for such installment or other payment. None of
such Borrower or any ERISA  Affiliate is required to provide  security to a Plan
under Section  401(a)(29) of the IRC due to a Plan  amendment that results in an
increase in current liability for the plan year.

          SECTION 3.12.  Investment  Company Act; Public Utility Holding Company
Act.  Such Borrower is not an  "investment  company" as that term is defined in,
and is not otherwise subject to regulation under, the Investment  Company Act of
1940.  Such Borrower is not a "holding  company" as that term is defined in, and
is not otherwise subject to regulation under, the Public Utility Holding Company
Act of 1935.

          SECTION  3.13.  Federal  Reserve  Regulations.  Such  Borrower  is not
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 of the Board of  Governors  of the Federal
Reserve System of the United  States),  and no part of the proceeds of the Loans
made to such Borrower will be used to purchase or carry any such margin stock or
to extend  credit to others for the purpose of  purchasing  or carrying any such
margin stock or for any purpose that  violates,  or is  inconsistent  with,  the
provisions of Regulation T, U or X of said Board of Governors.

          SECTION 3.14.  Collateral.  The security  interests granted by Article
VIII  hereof,  and  accompanying  financing  statements,  when duly filed in the
offices and  jurisdictions  set forth on Schedule 3.14 hereof,  create valid and
perfected  first  priority  Liens  in and to the  Collateral  of such  Borrower,
enforceable against other Persons in all jurisdictions  securing the payment, as
applicable, of the Obligations hereunder. Upon filing such financing statements,
to the extent that the filing of a financing  statement is sufficient to perfect


                                       47


a security  interest,  no further action is required to perfect the Liens of the
Collateral  Agent in favor of the  Lenders in the  Collateral  of such  Borrower
described in Section 8.01.

          SECTION 3.15.  Chief Place of Business.  As of the Closing  Date,  the
chief executive  office and principal place of business address of such Borrower
is 1545  Route 206,  Bedminster,  New  Jersey  07921.  If any change in any such
location  occurs,  such Borrower shall notify the Agent and the Collateral Agent
thereof not later than ten days after the occurrence  thereof. As of the date of
execution  hereof,  the books and records of such Borrower and all chattel paper
and all  records of account are  located at the  principal  place of business or
chief  executive  office of such  Borrower  and if any  change in such  location
occurs,  such Borrower shall notify the Agent and the  Collateral  Agent thereof

          SECTION 3.16. Other Corporate  Names.  Except as set forth on Schedule
3.16,  such  Borrower  has not  used  and  does not now use and will not use any
corporate or fictitious name.

          SECTION 3.17.  Insurance.  Schedule 3.17 contains a description of all
insurance which such Borrower  maintains or has maintained on its behalf. All of
such insurance is in full force and effect.

          SECTION 3.18. Milestone Plan. The Milestone Plan represents good faith
projections of future financial performance of the Borrowers for the periods set
forth therein.  Such document has been prepared on the basis of the  assumptions
set forth  therein,  which the  Borrowers  believe  are  reasonable  in light of
current and reasonably foreseeable business conditions.

          SECTION 3.19.  Capitalization and Subsidiaries.  The classes of Equity
Interests,  number of authorized  shares,  number of outstanding  shares and par
values or other  designations of the Equity Interests or other equity securities
or  beneficial  interests of such  Borrower are  correctly set forth on Schedule
3.19. All the outstanding  shares of Equity Interests or other equity securities
or beneficial interests of such Borrower are duly and validly issued, fully paid
and  nonassessable,  and none of such  issued  and  outstanding  shares,  equity
securities  or  beneficial  interests  has been  issued in  violation  of, or is

other  beneficial  interests  of  such  Borrower,   (B)  outstanding  rights  of
subscription,  warrants,  calls,  options,  contracts or other agreements of any
kind,  issued,  made or granted to or with any Person under which such  Borrower
may be obligated to issue, sell, purchase, retire or redeem or otherwise acquire
or dispose of any  shares of Equity  Interests  or other  equity  securities  or
beneficial interests of such Borrower, or (C) Subsidiaries of such Borrower. KMC
Holdings beneficially owns, directly or indirectly,  all of the Equity Interests
of such Borrower.


                                       48


          SECTION  3.20.  Real  Property,  Leases and  Easements.  Such Borrower

Solvent and is not contemplating either the filing of a petition by it under any
state or federal  bankruptcy or insolvency  laws or the  liquidation of all or a
substantial  portion  of its  property,  and  has  no  knowledge  of any  Person
contemplating the filing of any such petition against such Borrower.

          SECTION  3.22.  Brokers,  etc.  Such  Borrower  has not dealt with any
broker, finder,  commission agent or other similar Person in connection with the
Loans or the transactions being effected  contemporaneously with this Agreement,

complete assessment of the Year 2000 Problems and has a realistic and achievable

2000 Problems will have a Material Adverse Effect.


                                       49


                                   ARTICLE IV
                              CONDITIONS FOR LOANS

Collateral Agent, the Agent or any Lender be responsible for any representations
or warranties  made by or on behalf of such  Borrower to any  insurance  broker,

of the Collateral  Agent,  all financing  statements or other documents (and pay
the cost of filing or recording the same in all public offices deemed  necessary
by the  Collateral  Agent),  as the  Collateral  Agent  may  request,  in a form
satisfactory to the Collateral Agent, to perfect and keep perfected the security
interest in the Collateral  granted by such Borrower to the Collateral  Agent or
to otherwise  protect and preserve the  Collateral  and the  Collateral  Agent's
security interest therein or to enforce the Collateral Agent's security interest
in the Collateral.  Should such Borrower fail to do so, the Collateral  Agent is
authorized to sign any such financing  statements as such Borrower's agent. Such

this  Agreement  or  of a  financing  statement  is  sufficient  as a  financing
statement.

          SECTION 8.03.  Appointment of the  Collateral  Agent as the Borrowers'
Attorney-in-Fact.   Such  Borrower   hereby   irrevocably   designates,   makes,
constitutes and appoints the Collateral Agent (and all persons designated by the

authorizes the Collateral  Agent, in such  Borrower's or the Collateral  Agent's
name, to,  following the  occurrence  and during the  continuance of an Event of
Default: (i) demand payment of such Borrower's Accounts; (ii) enforce payment of


                                       76


such Borrower's  Accounts by legal proceedings or otherwise;  (iii) exercise all
of such  Borrower's  rights and remedies with respect to proceedings  brought to

amount and at such time or times as the Collateral  Agent deems  advisable;  (v)
settle,  adjust,  compromise,  extend or renew an Account;  (vi)  discharge  and

          SECTION   8.04.   Collection  of  Accounts  and   Restricted   Account
Arrangements.  Such Borrower hereby represents and warrants that each depository
account  ("Collection  Account")  now  maintained  by such  Borrower at any bank
("Collection Agent") for the collection of checks and cash constituting proceeds
of  Accounts  and  sales  of  other  personal  property  which  are  part of the
Collateral  is  identified  on  Schedule  8.04  attached  hereto and made a part
hereof. With respect to each Collection  Account,  such Borrower shall, no later
than the Initial  Funding Date,  deliver to the Collateral  Agent, a "Restricted
Account  Agreement"  substantially  in the form of Exhibit N attached hereto and
made a part  hereof,  duly  executed  and  delivered  by such  Borrower  and the
applicable  Collection  Agent,  authorizing and directing such Collection Agent,
upon  receipt  of  written  notice  from the  Collateral  Agent that an Event of
Default has occurred and is continuing,  to deposit all checks and cash received
into a  restricted  account  (a  "Restricted  Account")  and remit  all  amounts
deposited in such Restricted Account to the Collateral Agent's account specified
in such Restricted  Account  Agreement  until such time as the Collection  Agent
receives written notice from the Collateral  Agent rescinding such  instruction.
Such Borrower  shall,  following the occurrence and during the continuance of an
Event of Default and any subsequent  request by the Collateral  Agent  therefor,
take such further action as the Collateral  Agent may reasonably  deem desirable
to effect the  transfer of  exclusive  ownership  and control of the  Restricted
Accounts and all Collection  Accounts to the Collateral Agent.  Until all of the
Obligations  have been  indefeasibly  paid in full,  such Borrower agrees not to
enter into any  agreement  or execute  and  deliver  any  direction  which would
modify,  impair or adversely  affect the rights and  benefits of the  Collateral
Agent under any  Restricted  Account  Agreement.  Such Borrower  shall not open,
establish or maintain any  Collection  Account  (other than those  identified on
Schedule 8.04 hereto) without first having  delivered to the Collateral  Agent a
duly executed and delivered  Restricted  Account  Agreement with respect to such
Collection  Account.  Such Borrower shall notify the Collateral Agent in writing
not less than five (5) days  prior to the date it shall  open or  establish  any
Collection Account other than an account described on Schedule 8.04 hereto.


                                       77


          SECTION 8.05.  Cure Rights.  Such Borrower  expressly  authorizes  the
Collateral Agent, and the Collateral Agent may, but shall not be required to, at
any time and from time to time,  to take any and all action  that it  reasonably
determines  to be  necessary  or  desirable  to cure any  default  or  violation
(including  a payment  default)  of such  Borrower in  connection  with any real
estate lease,  license  agreement,  Governmental  Approval or any other material
lease, agreement or contract entered into with respect to the Systems.


                                   ARTICLE IX

Notes or any other  amounts  payable  hereunder  or under any of the other  Loan
Documents when due,  whether as scheduled,  at a date fixed for  prepayment,  by
acceleration or otherwise, and five (5) Business Days shall have elapsed; or

          (b) Any Borrower shall fail to observe or perform any other  covenant,
condition or  agreement  to be observed or performed by such  Borrower in any of
the Loan Documents,  and such Borrower fails to cure such breach within ten (10)
Business  Days after  written  notice  thereof  unless  the breach  relates to a
covenant  contained in Sections  5.04, or Article VI (other than Section 6.05 or
Section  6.07) or VII, in which case no notice or grace period  shall apply,  or
unless the breach  relates  to Section  5.06,  in which case an Event of Default
shall  occur on the  thirtieth  day  following  the  breach  without  any notice
requirement, unless the breach shall have been cured before such date; or

          (c)  Any  representation  or  warranty  made  by any  Borrower  or KMC
Holdings in connection  with this Agreement or any other Loan  Document,  or the
Loans  or any  statement  or  representation  made in any  report,  certificate,
financial  statement  or other  instrument  furnished  by or on  behalf  of such
Borrower or KMC Holdings  pursuant to this Agreement or any other Loan Document,
shall prove to have been false or misleading  in any material  respect when made
or delivered or when deemed made in accordance with the terms hereof or thereof;
or

          (d) Any  Borrower or KMC  Holdings  shall fail to make any payment due

specified in the agreement or instrument  relating to such indebtedness;  or any
other  default  or event  under any  agreement  or  instrument  relating  to any
indebtedness  for  borrowed  money in excess of  $250,000  with  respect  to any
Borrower or in excess of $1,000,000  with respect to KMC Holdings,  or any other
event, shall occur and shall continue after the applicable grace period, if any,
specified in such agreement or instrument if the effect of such default or event
is to  accelerate,  or to permit  the  acceleration  of,  the  maturity  of such


                                       78


indebtedness  in excess of $250,000 with respect to any Borrower or in excess of
$1,000,000 with respect to KMC Holdings;  or any such  indebtedness in excess of
$250,000 with respect to any Borrower or in excess of $1,000,000 with respect to
KMC  Holdings  shall be declared to be due and payable or required to be prepaid

debts, insolvency or receivership law is filed by or against any Borrower or KMC
Holdings,  or any Borrower or KMC Holdings  takes any action to authorize any of
the foregoing matters, and in the case of any such proceeding instituted against
any  Borrower  or KMC  Holdings  (but  not  instituted  by any  Borrower  or KMC
Holdings),  either such  proceeding  shall remain  undismissed or unstayed for a
period of 60 days or any of the actions  sought in such  proceeding  (including,
without limitation, the entry of an order for relief against, or the appointment
of a  receiver,  trustee  or other  similar  official  for any  Borrower  or KMC
Holdings  or any  substantial  part of its  property)  shall be granted or shall
occur; or

          (g) a  Termination  Event occurs which the  Requisite  Lenders in good
faith believe would subject any Borrower to a material liability; or

          (h) the plan administrator of any Plan applies under Section 412(d) of
the IRC for a waiver of the minimum  funding  standards of Section 412(a) of the
IRC and the  Requisite  Lenders in good faith  believe that the approval of such
waiver could subject any Borrower or any ERISA Affiliate to material  liability;

Governmental Approval or approval of or material filing with the FCC, any PUC or
any other Governmental  Authority with respect to the conduct by any Borrower of
its business and  operations,  including its Business,  shall not be obtained or
shall  cease to be in full  force and  effect,  which in  respect  of any of the
Governmental  Approvals  shall,  in the case of an order of the FCC,  any PUC or
other Governmental Authority having jurisdiction with respect thereto, revoking,
or  deciding  not to  renew,  any such  Governmental  Approval,  occur  upon the
issuance  of such  order,  and,  in the  case of any  other  order  revoking  or
terminating  any of the  Governmental  Approvals  or deciding  not to renew such
Governmental  Approvals prior to the termination thereof,  occur when such order
becomes final,  and in each case, with respect to any such event occurring on or
after the  Trigger  Date,  such event is also  reasonably  likely to result in a
Material Adverse Effect; or


                                       79


          (j) the FCC,  any PUC or any other  Governmental  Authority,  by final
order,  determines  that the existence or  performance  of this Agreement or any
other Loan Document will result in a revocation,  suspension or material adverse
modification  of any of the  Governmental  Approvals  for any  System,  and with
respect  to any such  event  occurring  on and  after  the  Trigger  Date,  such
determination is reasonably likely to result in a Material Adverse Effect; or

          (k) for any  reason any Loan  Document  shall not be in full force and
effect or shall not be enforceable in accordance with its terms, or any security
interest or lien granted pursuant  thereto with respect to Collateral  having an
aggregate value of $500,000 or greater shall fail to be perfected or to have its
intended  priority,  or any Borrower or any Affiliate  thereof shall contest the
validity of any Lien granted under, or shall disaffirm its obligations under any
Loan Document; or

          (l) any Borrower shall default under any Lucent Purchase  Agreement or
Additional Purchase Agreement, which default shall not have been cured or waived
within the applicable grace period thereunder unless such Borrower is contesting
such default in good faith by appropriate  protest or proceedings and shall have
set aside adequate reserves in accordance with GAAP; or

          (m) for any  reason,  any  Borrower  ceases to  operate  any System or
ceases to own any of its  Governmental  Approvals  necessary for the  continuing
operation  of any System,  and with  respect to any such event  occurring  on or
after the Trigger  Date,  such  cessation  is  reasonably  likely to result in a
Material Adverse Effect; or

          (n) a  judgment  or  judgments  for the  payment of money in excess of
$250,000  individually  or $500,000 in the  aggregate at any one time shall have
been rendered against any Borrower and the same shall have remained  unsatisfied
and in  effect  for any  period  of  sixty  (60)  days  during  which no stay of
execution shall have been obtained; or

          (o) any Borrower is enjoined,  restrained  or in any way  prevented by
the order of any court or  administrative  or regulatory  agency from conducting
its  business in any  material  respect  with  respect to any one or more of its
Systems  and with  respect to any such event  occurring  on or after the Trigger
Date, such event is reasonably likely to result in a Material Adverse Effect; or

          (p) any Borrower becomes subject to any liabilities,  costs, expenses,
damages,  fines or  penalties  which  could  reasonably  be  expected  to have a
Material  Adverse Effect arising out of or related to (i) any Remedial Action in
response to a Release or threatened  Release at any location of any  Contaminant
into the indoor or outdoor  environment  or (ii) any  material  violation of any
Environmental Law; or

          (q) a Change of Control shall occur; or

          (r) KMC  Holdings  shall  fail to observe  or  perform  any  covenant,
condition  or  agreement  to be observed or performed by KMC Holdings in the KMC
Holdings Guaranty; or


                                       80


          (s) any  Borrower  shall  fail to observe  or  perform  any  covenant,
condition  or  agreement  to be observed or  performed  by such  Borrower in any
material  agreement  (other than a Loan Document or an agreement  referred to in
Section  9.01(d)),  such  Borrower  fails to cure such  breach  within  ten (10)
Business Days after written notice thereof, and with respect to any such failure
occurring on or after the Trigger  Date,  such failure is  reasonably  likely to
result in a Material  Adverse  Effect,  unless such Borrower is contesting  such
covenant, condition or agreement by appropriate protest or proceedings and shall
have set aside adequate reserves in accordance with GAAP.

          SECTION  9.02.  Termination  of  Commitment;  Acceleration.  Upon  the
occurrence and at any time during the  continuance of any Event of Default,  the
Agent shall upon direction from the Requisite Lenders:

          (a) by notice to the Borrowers,  terminate Lenders' Commitment to make
Loans hereunder; or

          (b)  by  notice  to  the  Borrowers,  declare  the  Obligations  to be
immediately due and payable,  whereupon all the Obligations shall be immediately
due and payable without further notice of any kind, provided,  however,  that if
an Event of Default  described in Section  9.01(f) shall exist or occur,  all of
the Obligations shall automatically,  without declaration or notice of any kind,
be  immediately  due and  payable  and the  Commitment  shall  be  automatically
terminated.

          SECTION 9.03.  Waivers.  Demand,  presentment,  protest and notices of
nonpayment, protest, dishonor and acceptance are hereby waived by each Borrower.
Each Borrower also waives the benefit of all valuation,  appraisal and exemption
laws and the posting of any bond required of the Collateral  Agent, the Agent or
any Lender in connection with any judicial process to realize on the Collateral,
to enforce any judgment or other court order entered in favor of the  Collateral
Agent, the Agent or any Lender or to enforce by specific performance,  temporary
restraining order, or preliminary or permanent injunction, this Agreement or any
other Loan Documents. Each Borrower waives the right, if any, to the benefit of,
or  to  direct  the  application  of,  any  Collateral.   Each  Borrower  hereby
acknowledges  that none of the Collateral Agent, the Agent or any Lender has any
obligation  to resort to any  Collateral  or make claim against any other Person
before seeking payment or performance from any Borrower.

          SECTION 9.04.  Rights and Remedies  Generally.  If an Event of Default
occurs and is  continuing,  the Agent and the  Collateral  Agent shall have,  in
addition to any other rights and remedies  contained in this Agreement or in any
of the other Loan  Documents,  all of the rights and remedies of a secured party
under the Code or other  applicable laws, all of which rights and remedies shall
be cumulative,  and none exclusive,  to the extent permitted by law. In addition
to all such rights and remedies,  the sale,  lease or other  disposition  of the
Collateral,  or any part thereof, by the Collateral Agent or the Agent after the
occurrence  of an Event of Default  may be for cash,  credit or any  combination
thereof,  and the Collateral  Agent or the Agent may purchase all or any part of
the  Collateral at public or, if permitted by law,  private sale, and in lieu of
actual payment of such purchase  price,  may set off the amount of such purchase
price against the  Obligations  then owing.  Any sales of the  Collateral may be
adjourned from time to time with or without notice.  The Agent or the Collateral


                                       81


Agent,  may,  in its sole  discretion,  cause  the  Collateral  to remain on the
premises of any Borrower, at the expense of the Borrowers, pending sale or other
disposition of the Collateral.  The Agent or the Collateral Agent shall have the
right to conduct such sales on the premises of any  Borrower,  at the expense of
the Borrowers, or elsewhere, on such occasion or occasions as it may see fit.

          SECTION  9.05.  Entry Upon Premises and Access to  Information.  If an
Event of Default  occurs and is continuing,  the Agent and the Collateral  Agent
shall  have the  right to enter  upon the  premises  of any  Borrower  where any
Collateral is located (or is believed to be located)  without any  obligation to
pay rent to such Borrower,  or any other place or places where the Collateral is
believed to be located and kept,  and render the  Collateral  unusable or remove
the Collateral therefrom to the premises of the Agent or the Collateral Agent or
any agent of the Agent or the  Collateral  Agent,  for such time as the Agent or
the Collateral  Agent may desire,  in order  effectively to collect or liquidate
the  Collateral,  and/or  the  Agent or the  Collateral  Agent may  require  any
Borrower to assemble  the  Collateral  and make it available to the Agent or the
Collateral  Agent at a place or  places  to be  designated  by the  Agent or the
Collateral Agent. If an Event of Default occurs and is continuing,  the Agent or
the  Collateral  Agent shall have the right to obtain  access to any  Borrower's
data  processing  equipment,  computer  hardware  and  software  relating to the
Collateral and to use all of the foregoing and the information contained therein
in any manner the Agent or the Collateral Agent deems appropriate.

          SECTION 9.06.  Sale or Other  Disposition  of Collateral by the Agent.
Any notice required to be given by the Agent or the Collateral  Agent of a sale,
lease  or  other  disposition  or  other  intended  action  by the  Agent or the
Collateral Agent with respect to any of the Collateral which is deposited in the
United States mails, registered or certified, postage prepaid and duly addressed
to the Borrowers at the address  specified in Section 11.01 below,  at least ten
days prior to such proposed action shall  constitute fair and reasonable  notice
to the Borrowers of any such action.  The net proceeds  realized by the Agent or
the Collateral  Agent upon any such sale or other  disposition,  after deduction
for the expense of retaking,  holding,  preparing for sale,  selling or the like
and the reasonable  attorneys' fees and legal expenses  incurred by the Agent or
the  Collateral  Agent in  connection  therewith,  shall be applied as  provided
herein  toward  satisfaction  of the  Obligations.  The Agent or the  Collateral
Agent,  as applicable,  shall account to the Borrowers for any surplus  realized
upon such sale or other  disposition,  and the Borrowers shall remain liable for
any  deficiency.  The  commencement  of any action,  legal or equitable,  or the
rendering  of any  judgment  or decree for any  deficiency  shall not affect the
Collateral Agent's security interest in the Collateral. The Borrowers agree that
the  Collateral  Agent has no  obligation to preserve  rights to the  Collateral
against any other parties. The Agent and the Collateral Agent are hereby granted
a license or other right to use, without charge, the Borrowers' labels, patents,
copyrights,  rights of use of any name, trade secrets, trade names,  trademarks,
service marks and advertising matter, or any property of a similar nature, as it
pertains to the Collateral, and the Borrowers' rights under all licenses and all
franchise  agreements  shall  inure to the Agent's  and the  Collateral  Agent's
benefit until the Obligations are paid in full.

          SECTION  9.07.   Governmental   Approvals.   In  connection  with  the
enforcement by the Agent or the Collateral Agent of any remedies available to it
as a result of any Event of Default, each Borrower agrees that it shall join and


                                       82


cooperate fully with, at the request of the Agent or the Collateral  Agent,  any
receiver  referred  to below  and/or  the  successful  bidder or  bidders at any
foreclosure  sale in a filing of an application  (and  furnishing any additional
information  that may be required in connection  with such  application or which
the Agent or the Collateral Agent may believe relevant to such application) with
the FCC, any PUC and all other applicable Governmental  Authorities,  requesting
their prior  approval of (i) the operation or  abandonment of all or the portion
of any System and/or (ii) the transfer of control of such Borrower or assignment
of all licenses,  certificates,  Governmental Approvals,  approvals and permits,
issued to such Borrower by the FCC, any PUC or any such Governmental Authorities
with  respect  to any  System  and the  operation  thereof,  to the Agent or the
Collateral  Agent,  the  receiver or to the  successful  bidder or  bidders.  In
connection  with the foregoing,  each Borrower shall take such further  actions,
and  execute  all  such  instruments,  as  the  Agent  or the  Collateral  Agent
reasonably deems necessary or desirable.  Each Borrower agrees that the Agent or
the Collateral Agent may enforce any obligation of such Borrower as set forth in
this section by an action for specific performance.  In addition,  each Borrower
hereby  irrevocably  constitutes and appoints the Agent and the Collateral Agent
and any agent or officer thereof (which appointment is coupled with an interest)
as its  true  and  lawful  attorney-in-fact  with  full  irrevocable  power  and
authority  and in the place and stead of such  Borrower  and in the name of such
Borrower  or in its own  name,  from  time to time in its  discretion  after the
occurrence  and during the  continuance of an Event of Default and in connection
with the  foregoing,  for the purpose of  executing on behalf and in the name of
such Borrower any and all of the  above-referenced  instruments  and to take any
and all appropriate action in furtherance of the foregoing.  THE EXERCISE OF ANY
RIGHTS OR REMEDIES HEREUNDER OR UNDER ANY OTHER LOAN DOCUMENT BY ANY LENDER, THE
AGENT  OR THE  COLLATERAL  AGENT  THAT MAY  REQUIRE  FCC,  ANY PUC OR ANY  OTHER
GOVERNMENTAL  AUTHORITY  APPROVAL  SHALL BE SUBJECT TO OBTAINING  SUCH APPROVAL.
PENDING  THE  RECEIPT OF ANY FCC,  ANY PUC OR ANY OTHER  GOVERNMENTAL  AUTHORITY
APPROVAL, NO BORROWER SHALL DO ANYTHING TO DELAY, HINDER,  INTERFERE OR OBSTRUCT
THE  EXERCISE  OF THE  AGENT'S  OR THE  COLLATERAL  AGENT'S  RIGHTS OR  REMEDIES
HEREUNDER IN OBTAINING SUCH APPROVALS.

          SECTION 9.08.  Appointment of Receiver or Trustee.  In connection with
the exercise of its remedies under this  Agreement,  the Agent or the Collateral
Agent may, upon the occurrence of an Event of Default, obtain the appointment of
a receiver or trustee to assume,  upon receipt of all necessary  judicial,  FCC,
any PUC or other  Governmental  Authority  consents or approvals,  control of or
ownership of any of the Governmental  Approvals.  Such receiver or trustee shall
have all rights and powers  provided  to it by law or by court order or provided
to the Agent or the Collateral Agent under this Agreement.  Upon the appointment
of such trustee or receiver,  the Borrowers  agree to  cooperate,  to the extent
necessary or appropriate,  in the expeditious preparation,  execution and filing
of an application to the FCC, any PUC or any other Governmental Authority or for
consent to the transfer of control or assignment of any Borrower's  Governmental
Approvals to the receiver or trustee.

          SECTION  9.09.  Right of  Setoff.  In  addition  to any  rights now or
hereafter  granted under applicable law and not by way of limitation of any such
rights,  upon the occurrence and during the continuance of any Event of Default,
each Lender and each holder of any Note is hereby authorized at any time or from
time to time,  without  notice to any Borrower or to any other Person,  any such


                                       83


notice being hereby expressly waived, to set off and to appropriate and to apply
any and all  balances  held by it at any of its  offices  for the account of any
Borrower (regardless of whether such balances are then due to such Borrower) and
any other  properties  or assets  any time held or owing by that  Lender or that
holder to or for the credit or for the  account of any  Borrower  against and on
account  of any of the  Obligations  which are not paid when due.  Any Lender or
holder of any Note  exercising  a right to set off or  otherwise  receiving  any
payment on account of the  Obligations  in excess of its Pro Rata Share  thereof
shall  purchase  for cash (and the other  Lenders  or holders  shall  sell) such
participation  in each such other  Lender's  or  holder's  Pro Rata Share of the
Obligations  as would be  necessary  to cause such Lender to share the amount so
set off or otherwise  received  with each other  Lender or holder in  accordance
with their  respective  Pro Rata Shares.  Each Borrower  agrees,  to the fullest
extent permitted by law, that (a) any Lender or holder may exercise its right to
set off  with  respect  to  amounts  in  excess  of its Pro  Rata  Share  of the
Obligations  and may  sell  participations  in such  amount  so set off to other
Lenders and holders and (b) any Lender or holder so  purchasing a  participation
in the Loans made or other  Obligations  held by other  Lenders  or holders  may
exercise all rights of set-off,  bankers' lien,  counterclaim  or similar rights
with respect to such  participation  as fully as if such Lender or holder were a
direct  holder  of the Loans and the  other  Obligations  in the  amount of such
participation.  Notwithstanding  the  foregoing,  if all or any  portion  of the
set-off amount or payment  otherwise  received is thereafter  recovered from the
Lender that has exercised the right of set-off,  the purchase of  participations
by that Lender  shall be  rescinded  and the  purchase  price  restored  without
interest. Each Borrower hereby agrees that the foregoing provisions are intended
to be construed so as to satisfy the  requirements of Section 553 of the Federal
Bankruptcy Code or amendments thereto (including any requirement of mutuality of
obligations therein).


                                    ARTICLE X
                       THE AGENT AND THE COLLATERAL AGENT

          SECTION 10.01.  Appointment of Agent. (a) First Union National Bank is
hereby appointed to act as contractual  representative  on behalf of all Lenders
under this  Agreement and the other Loan  Documents.  The Agent agrees to act as
such contractual  representative  upon the express conditions  contained in this
Article X. The  provisions  of this Section  10.01 are solely for the benefit of
the Agent and the Lenders and no  Borrower  or any other  Person  shall have any
rights  as a  third  party  beneficiary  of  any of the  provisions  hereof.  In
performing  its  functions  and duties under this  Agreement  and the other Loan
Documents,  the Agent  shall act solely as an agent of the  Lenders and does not
assume  and  shall  not be  deemed  to have  assumed  any  obligation  toward or
relationship  of agency or trust with or for any  Borrower or any other  Person.
The Agent shall have no duties or  responsibilities  except for those  expressly
set forth in this Agreement and the other Loan  Documents.  Notwithstanding  the
use of the defined term "Agent", it is expressly  understood and agreed that the
Agent shall not have any fiduciary  responsibilities  to any Lender by reason of
this Agreement and that the Agent is merely acting as the  representative of the
Lenders with only those duties as are expressly set forth in this  Agreement and
the  other  Loan  Documents.   In  its  capacity  as  the  Lenders'  contractual
representative, the Agent (i) does not assume any fiduciary duties to any of the
Lenders, (ii) is a "representative" of the Lenders within the meaning of Section


                                       84


9-105 of the UCC and (iii) is acting as an  independent  contractor,  the rights
and duties of which are limited to those  expressly set forth in this  Agreement
and the other  Loan  Documents.  Each of the  Lenders  agrees to assert no claim
against  the Agent on any agency  theory or any other  theory of  liability  for
breach of fiduciary  duty, all of which claims each Lender  waives.  Neither the
Agent nor any of its Affiliates nor any of their respective officers, directors,
employees,  agents or  representatives  shall be liable  to any  Lender  for any
action  taken or  omitted  to be taken by it  hereunder  or under any other Loan
Document,  or in connection herewith or therewith,  except for damages caused by
its or their own gross negligence or willful misconduct.

          (b)  If  the  Agent  shall  request  instructions  from  all  Lenders,
Requisite  Lenders,  Requisite  Revolving  Lenders or all affected  Lenders with
respect to any act or action (including  failure to act) in connection with this
Agreement  or any other  Loan  Document,  then the Agent  shall be  entitled  to
refrain  from such act or taking  such  action  unless and until the Agent shall
have  received  instructions  from all  Lenders,  Requisite  Lenders,  Requisite
Revolving  Lenders or all  affected  Lenders,  as the case may be, and the Agent
shall not incur  liability to any Person by reason of so  refraining.  The Agent
shall be fully justified in failing or refusing to take any action  hereunder or
under any other Loan  Document (a) if such action  would,  in the opinion of the
Agent,  be  contrary  to law or the terms of this  Agreement  or any other  Loan
Document,  (b) if such action  would,  in the  opinion of the Agent,  expose the
Agent to  liabilities  beyond the limits of this  Agreement  or (c) if the Agent
shall not first be indemnified to its satisfaction against any and all liability
and expense  which may be incurred  by it by reason of taking or  continuing  to
take any such action.  Without limiting the foregoing,  no Lender shall have any
right of action whatsoever  against the Agent as a result of the Agent acting or
refraining from acting  hereunder or under any other Loan Document in accordance
with the instructions of all Lenders,  Requisite  Lenders,  Requisite  Revolving
Lenders or all affected Lenders, as applicable.

          SECTION 10.02. Agent's Reliance, Etc. Neither the Agent nor any of its
Affiliates nor any of their respective directors,  officers, agents or employees
shall be liable for any action  taken or omitted to be taken by it or them under
or in connection  with this  Agreement or the other Loan  Documents,  except for
damages  caused by its or their  own gross  negligence  or  willful  misconduct.
Without limitation of the generality of the foregoing,  the Agent: (a) may treat
the payee of any Note as the holder  thereof  until the Agent  receives  written
notice of the  assignment or transfer  thereof  signed by such payee and in form
satisfactory  to the Agent;  (b) may  consult  with legal  counsel,  independent
public  accountants and other experts selected by it 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;  (c) makes no warranty or
representation  to any Lender and shall not be responsible to any Lender for any
statements,  warranties or  representations  made in or in connection  with this
Agreement or the other Loan Documents;  (d) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms, covenants
or conditions of this  Agreement or the other Loan  Documents on the part of any
Borrower or to inspect the  Collateral  (including  the books and records);  (e)
shall  not be  responsible  to any  Lender  for  the  due  execution,  legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
the other Loan Documents or any other instrument or document  furnished pursuant
hereto or thereto;  and (f) shall incur no liability under or in respect of this


                                       85


Agreement  or the other  Loan  Documents  by acting  upon any  notice,  consent,
certificate or other instrument or writing (which may be by telecopy,  telegram,
cable or telex)  believed  by it to be genuine  and signed or sent by the proper
party or parties.

          SECTION 10.03.  FUNB and  Affiliates.  With respect to its Commitments
hereunder,  FUNB shall have the same rights and powers under this  Agreement and
the other Loan Documents as any other Lender and may exercise the same as though
it were  not the  Agent;  and the  term  "Lender"  or  "Lenders"  shall,  unless
otherwise expressly indicated, include FUNB in its individual capacity. FUNB and
its Affiliates may lend money to, invest in, and generally engage in any kind of
business  with,  any Borrower,  any of its  Affiliates and any Person who may do
business with or own securities of any Borrower or any such Affiliate, all as if
FUNB were not the Agent and  without  any duty to account  therefor  to Lenders.
FUNB and its  Affiliates  may  accept  fees  and  other  consideration  from any
Borrower for services in  connection  with this  Agreement or otherwise  without
having to account for the same to Lenders. FUNB may also purchase or hold Equity
Interests  or warrants in KMC  Holdings or any  Borrower  and make  subordinated
loans to any  Borrower.  Each  Lender  acknowledges  the  potential  conflict of
interest  between  FUNB as a Lender  holding  disproportionate  interests in the
Loans, FUNB as a member or subordinated debt holder, of the Borrower and FUNB as
Agent.

          SECTION 10.04.  Lender Credit Decision.  Each Lender acknowledges that
it has,  independently  and without  reliance upon the Agent or any other Lender
and based on the financial  information given it by the Borrowers and such other
documents and information as it has deemed appropriate,  made its own credit and
financial  analysis  of the  Borrowers  and its own  decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance  upon the Agent or any other  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 this  Agreement.  Each
Lender acknowledges the potential conflict of interest of each other Lender as a
result of Lenders holding disproportionate interests in the Loans, and expressly
consents to, and waives any claim based upon, such conflict of interest.

          SECTION  10.05.  Indemnification.   Each  of  the  Lenders  agrees  to
indemnify  the Agent (to the extent not  reimbursed by the Borrowers and without
limiting the  obligations of Borrowers  hereunder),  ratably  according to their
respective  Pro  Rata  Shares,   from  and  against  any  and  all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements of any kind or nature  whatsoever which may be imposed
on, incurred by, or asserted against the Agent in any way relating to or arising
out of this  Agreement or any other Loan Document or any action taken or omitted
by the Agent in connection therewith; provided, however, that no Lender shall be
liable  for any  portion  of such  liabilities,  obligations,  losses,  damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Agent's gross  negligence or willful  misconduct.  Without limiting the
foregoing,  each Lender agrees to reimburse  the Agent  promptly upon demand for
its  ratable  share  of any  out-of-pocket  expenses  (including  counsel  fees)
incurred by the Agent in connection with the preparation,  execution,  delivery,
administration,   modification,   amendment  or  enforcement   (whether  through
negotiations,  legal proceedings or otherwise) of, or legal advice in respect of


                                       86


rights or  responsibilities  under, this Agreement and each other Loan Document,
to the  extent  that  the  Agent is not  reimbursed  for  such  expenses  by the
Borrowers.

          SECTION 10.06.  Successor  Agent.  The Agent may resign at any time by
giving not less than thirty (30) days' prior written  notice  thereof to Lenders
and the Borrowers.  Upon any such resignation,  the Requisite Lenders shall have
the right to appoint a successor Agent. If no successor Agent shall have been so
appointed by the  Requisite  Lenders and shall have  accepted  such  appointment
within 30 days after the resigning  Agent's giving notice of  resignation,  then
the resigning Agent may, on behalf of Lenders,  appoint a successor Agent, which
shall be a  Lender,  if a Lender  is  willing  to accept  such  appointment,  or
otherwise shall be a commercial bank or financial institution or a subsidiary of
a commercial bank or financial  institution if such commercial bank or financial
institution  is organized  under the laws of the United  States of America or of
any  State  thereof  and  has  a  combined  capital  and  surplus  of  at  least
$300,000,000.  If  no  successor  Agent  has  been  appointed  pursuant  to  the
foregoing,  by the 30th day after the date such notice of resignation  was given
by the  resigning  Agent,  such  resignation  shall  become  effective  and  the
Requisite  Lenders shall  thereafter  perform all the duties of Agent  hereunder
until such time, if any, as the Requisite  Lenders  appoint a successor Agent as
provided above. Any successor Agent appointed by the Requisite Lenders hereunder
shall  be  subject  to  the  approval  of  Borrowers,  such  approval  not to be
unreasonably  withheld  or delayed;  provided  that such  approval  shall not be
required  if a  Default  or an Event  of  Default  shall  have  occurred  and be
continuing.  Upon the  acceptance  of any  appointment  as Agent  hereunder by a
successor  Agent,  such successor  Agent shall succeed to and become vested with
all the rights,  powers,  privileges and duties of the resigning Agent. Upon the
earlier of the acceptance of any  appointment as Agent  hereunder by a successor
Agent or the effective date of the resigning Agent's resignation,  the resigning
Agent shall be discharged from its duties and  obligations  under this Agreement
and the other Loan Documents,  except that any indemnity  rights or other rights
in favor of such resigning  Agent shall  continue.  After any resigning  Agent's
resignation  hereunder,  the provisions of this Section 10.06 shall inure to its
benefit as to any actions  taken or omitted to be taken by it while it was Agent
under this Agreement and the other Loan Documents.

          SECTION 10.07. Payments; Non-Funding Lenders; Information;  Actions in
Concert.

          (a)  Loans;  Payments.  Whenever  the  Agent  receives  a  payment  of
principal,  interest,  fee or premium (if any) or other payment, or whenever the
Agent makes an application of funds,  in connection  with the Loans or the Notes
(including, without limitation, any payment or application from any Collateral),
the Agent will on the date such  payment is received or applied,  if on or prior
to 11:00 a.m.  (Eastern  time) on such date,  or otherwise on the next  Business
Day, pay over to each Lender as instructed by such Lender in writing,  an amount
equal to such Lender's Pro Rata Share of such payment  provided that such Lender
has  funded  all  Loans  required  to  be  made  by it  and  has  purchased  all
participation  required to be purchased by it under this Agreement and the other
Loan  Documents as of such date.  To the extent that any Lender (a  "Non-Funding
Lender")  has failed to fund all such  payments  and Loans or failed to fund the
purchase of all such  participation,  the Agent shall be entitled to set off the
funding  short-fall  against  that  Non-Funding  Lender's  Pro Rata Share of all
payments  received  from the  Borrowers.  All payments by Agent shall be made by
wire transfer to such  Lender's  account (as specified by such Lender) not later
than 2:00 p.m. (Eastern time) on the applicable Business Day.

                                       87


          (b) Return of Payments.  (i) If Agent pays an amount to a Lender under
this Agreement in the belief or expectation  that a related  payment has been or
will be received by the Agent from the Borrowers and such related payment is not
received by Agent,  then the Agent will be entitled to recover  such amount from
such Lender on demand without set-off, counterclaim or deduction of any kind.

               (ii) If the Agent determines at any time that any amount received
          by the Agent under this  Agreement must be returned to any Borrower or
          paid to any other Person  pursuant to any insolvency law or otherwise,
          then, notwithstanding any other term or condition of this Agreement or
          any other Loan Document,  the Agent will not be required to distribute
          any portion thereof to any Lender. In addition, each Lender will repay
          to Agent on  demand  any  portion  of such  amount  that the Agent has
          distributed  to such Lender,  together  with interest at such rate, if
          any,  as the Agent is  required  to pay to any  Borrower or such other
          Person, without set-off, counterclaim or deduction of any kind.

          (c) Non-Funding Lenders. The failure of any Non-Funding Lender to make
any portion of its Loans or any payment  required  by it  hereunder  on the date
specified  therefor  shall not relieve any other Lender (each such other Lender,
an "Other  Lender") of its  obligations  to make any such Loan on such date, but
neither any Other Lender nor the Agent shall be  responsible  for the failure of
any  Non-Funding  Lender to make any Loan.  Notwithstanding  anything  set forth
herein to the  contrary,  a  Non-Funding  Lender  shall  not have any  voting or
consent  rights  under or with  respect to any Loan  Document  or  constitute  a
"Lender" (or be included in the calculation of "Requisite Lenders" or "Requisite
Revolving  Lenders"  hereunder)  for any voting or consent  rights under or with
respect to any Loan Document.

          (d)  Dissemination  of  Information.  The  Agent  will use  reasonable
efforts  to  provide  Lenders  with any  notice of  Default  or Event of Default
received by the Agent from,  or delivered by the Agent to, the  Borrowers,  with
notice of any Event of Default of which the Agent has actually  become aware and
with  notice of any action  taken by the Agent  following  any Event of Default;
provided,  however,  that the Agent  shall not be liable to any  Lender  for any
failure to do so, except to the extent that such failure is  attributable to the
Agent's gross  negligence or willful  misconduct.  Lenders  acknowledge that the
Borrowers are required to provide  financial  statements and other  documents to
Lenders  pursuant to this  Agreement and agree that the Agent shall have no duty
to provide the same to Lenders.

          (e) Actions in Concert.  Anything in this  Agreement  to the  contrary
notwithstanding, each Lender hereby agrees with each other Lender that no Lender
shall  take any action to protect  or  enforce  its rights  arising  out of this
Agreement  or the Notes  (including  exercising  any rights of set-off)  without
first obtaining the prior written consent of the Agent and Requisite Lenders, it
being the intent of Lenders  that any such  action to protect or enforce  rights
under  this  Agreement  and the  Notes  shall  be taken  in  concert  and at the
direction or with the consent of Agent.


                                       88


          SECTION 10.08. Collateral Matters.

          (a) The Lenders hereby irrevocably  authorize the Collateral Agent, at
its option and in its reasonable business judgment, to release any Lien upon any
Collateral  (i)  upon  the  termination  of  the  Commitments  and  payment  and
satisfaction  of all Loans and all other  Obligations  and which the  Collateral
Agent has been notified in writing are then due and payable;  (ii)  constituting
property being sold or disposed of if the applicable  Borrower  certifies to the
Collateral Agent that the sale or disposition is made in compliance with Section
6.03 (and the Collateral  Agent may rely  conclusively on any such  certificate,
without  further  inquiry);   or  (iii)  constituting  property  leased  to  the
applicable  Borrower  under a lease  which has expired or been  terminated  in a
transaction  permitted under this Agreement or which will expire  imminently and
which has not been,  and is not  intended  by such  Borrower  to be,  renewed or
extended and with respect to which such  Borrower has not exercised any purchase
option.  Except as provided above,  the Collateral Agent will not release any of
the Liens without the prior  written  authorization  of the  Requisite  Lenders;
provided  that the  Collateral  Agent may not  release  the Liens on  Collateral
valued in the  aggregate  in  excess  of  $500,000  without  the  prior  written
authorization of the Requisite  Lenders and may not release all or substantially
all of the  Collateral  without the consent of the Lenders.  Upon request by the
Collateral  Agent or the  Borrowers  at any time,  the Lenders  will  confirm in
writing the Collateral  Agent's  authority to release any Liens upon  particular
types or items of Collateral pursuant to this Section 10.08(a).

          (b) Upon receipt by the Collateral Agent of any authorization required
pursuant  to  Section  10.08(a)  from  the  Requisite  Lenders  or  Lenders,  as
applicable,  of the  Collateral  Agent's  authority  to  release  any Liens upon
particular  types or items of  Collateral,  and upon at least five (5)  Business
Days' prior written  request by the  applicable  Borrower,  and provided that no
Event of Default has occurred and is then continuing, the Collateral Agent shall
(and is hereby irre vocably authorized by the Lenders to) execute such documents
as may be necessary  to evidence the release of the Liens upon such  Collateral;
provided,  however,  that (i) the  Collateral  Agent  shall not be  required  to
execute any such document on terms which,  in the  Collateral  Agent's  opinion,
would  expose the  Collateral  Agent to liability  or create any  obligation  or
entail any consequence  other than the release of such Liens without recourse or
warranty,  and (ii) such release  shall not in any manner  discharge,  affect or
impair the  Obligations or any Liens (other than those expressly being released)
upon (or  obligations  of the  applicable  Borrower in respect of) all interests
retained by the applicable Borrower, including (without limitation) the proceeds
of any sale, all of which shall continue to constitute part of the Collateral.

          (c) The Collateral Agent shall have no obligation whatsoever to any of
the Lenders to assure that the Collateral  exists or is owned by any Borrower or
is cared for, protected or insured or has been encumbered, or, other than a duty
to act  without  recklessness,  willful  misconduct  or  gross  (but  not  mere)
negligence,  that the Liens  have been  properly  or  sufficiently  or  lawfully
created,  perfected,  protected  or enforced or are  entitled to any  particular
priority, or to exercise at all or in any particular manner or under any duty of
care,  disclosure  or fidelity,  or to continue  exercising,  any of the rights,
authorities  and powers  granted or  available  to the  pursuant to this Section
10.08 or pursuant to any of the Loan Documents,  it being  understood and agreed
that in  respect  of the  Collateral,  or any act,  omission  or  event  related
thereto, the Collateral Agent may act in any manner it may deem appropriate,  in


                                       89


its reasonable  business judgment,  given the Collateral Agent's own interest in
the  Collateral  in its  capacity as one of the Lenders and that the  Collateral
Agent shall have no other duty or liability  whatsoever  to any Lender as to any
of the foregoing.

          SECTION 10.09. Agency for Perfection. Each Lender hereby appoints each
other  Lender as agent for the  purpose  of  perfecting  the  Lenders'  security
interest  in  assets  which,  in  accordance  with  Article  9 of the UCC can be
perfected  only by  possession.  Should any Lender  (other  than the  Collateral
Agent) obtain  possession of any such  Collateral,  such Lender shall notify the
Collateral  Agent thereof,  and,  promptly upon the Collateral  Agent's  request
therefor shall deliver such Collateral to the Collateral Agent.

          SECTION  10.10.   Concerning  the  Collateral  and  the  Related  Loan
Documents and the Collateral  Agent. (a) Each Lender  authorizes and directs the
Collateral  Agent to enter  into this  Agreement  and the other  Loan  Documents
relating to the Collateral,  for the ratable benefit of the Lenders. Each Lender
agrees that any action taken by the  Collateral  Agent or  Requisite  Lenders in
accordance with the terms of this Agreement or the other Loan Documents relating
to the  Collateral,  and the exercise by the  Collateral  Agent or the Requisite
Lenders of their  respective  powers set forth therein or herein,  together with
such other powers that are reasonably incidental thereto,  shall be binding upon
all of the Lenders.

          (b) The  Collateral  Agent with respect to the  administration  of the
Collateral  shall have the same rights,  obligations  and status as the Agent as
are set forth in Section 10.01, 10.02, 10.03, 10.04, 10.05, and 10.06 above.


                                   ARTICLE XI
                                  MISCELLANEOUS

          SECTION 11.01. Notices;  Action on Notices, etc. (a) Notices and other
communications provided for herein shall be in writing and shall be delivered by
a courier service of recognized standing  (specifying one (1) day delivery),  or
by registered or certified mail, postage prepaid,  return receipt requested (or,
if by telecopy communications  equipment of the sending party, delivered by such

719-8775,  confirmation no. (908) 470-2200) with a copy to Alan M. Epstein Esq.,

AT&T Commercial Finance, Two Gatehall Drive,  Parsippany,  NJ 07054,  Attention:
Media and Communications,  (telecopy no. (973) 355-7644,  confirmation no. (973)
355-7630).  All notices and other  communications  given to any party  hereto in
accordance  with the provisions of this  Agreement  shall be deemed to have been
given (a) five  Business Days after mailing when sent by registered or certified
mail,  postage prepaid,  return receipt  requested,  or (b) upon receipt,  if by


                                       90


courier service or any telecopy communications  equipment of the sender, in each
case  addressed to such party as provided in this Section or in accordance  with
the latest unrevoked direction from such party.

          (b) Each Borrower  agrees that the Agent or the  Collateral  Agent may
act upon any notice, consent,  certificate,  cable, telex or other instrument or
writing  believed by the Agent or the Collateral  Agent to be genuine,  that the
Agent or the Collateral  Agent may consult with legal  counsel,  selected by the
Agent or the  Collateral  Agent and shall not be liable to any  Borrower for any
action taken or omitted to be taken in good faith by Lender in  accordance  with
the advice of such counsel.

          SECTION 11.02. No Waivers;  Amendments. (a) No failure or delay of the
Agent,  the  Collateral  Agent or any Lender to exercise any right  hereunder or
under any other Loan Document shall operate as a waiver  thereof,  nor shall any
single or partial  exercise  of any such  right,  preclude  any other or further
exercise  thereof or the exercise of any other right. No waiver of any provision
of this Agreement or any other Loan Document nor consent to any departure by any
Borrower  therefrom shall in any event be effective  unless the same shall be in
writing and signed by the Agent and the Requisite Lenders,  and then such waiver
or consent shall be effective only in the specific  instance and for the purpose
for which given.  No notice or demand on any Borrower in any case shall  entitle
any  Borrower  to any other or  further  notice or  demand in  similar  or other
circumstances.

          (b) Subject to the provisions of this Section 11.02(b),  the Requisite
Lenders (or the Agent with the consent in writing of the Requisite  Lenders) and
the Borrowers may enter into agreements  supplemental  hereto for the purpose of
adding or  modifying  any  provisions  to the Loan  Documents or changing in any
manner the rights of the Lenders or the Borrowers hereunder or waiving any Event
of Default or Default hereunder;  provided,  however,  that no such supplemental
agreement shall, without the consent of each Lender affected thereby:

               (i)   Postpone  or  extend  the   Revolving   Credit   Commitment
          Termination  Date,  the maturity  date for the loans or any other date
          fixed for any payment of  principal  of, or interest  on, the Loans or
          any fees or other  amounts  payable to such Lender except with respect
          to (A) any modifications of the provisions  relating to prepayments of
          Loans and other Obligations and (B) a waiver of the application of the
          default rate of interest pursuant to Section 2.05(b) hereof.

               (ii) Reduce the principal amount of any Loans, or reduce the rate
          or extend the time of payment of interest or fees thereon.

               (iii)  Reduce  the  percentage  specified  in the  definition  of
          Requisite  Lenders  or  Requisite   Revolving  Lenders  or  any  other
          percentage  of Lenders  specified to be the  applicable  percentage in
          this Agreement to act on specified  matters or amend the definition of
          "Pro Rata Share".


                                       91


               (iv)  Increase  the  amount  of  any  Commitment  of  any  Lender
          hereunder or increase any Lender's Pro Rata Share.

               (v)  Permit  any   Borrower  to  assign  its  rights  under  this
          Agreement.

               (vi) Release all or substantially all of the Collateral.

               (vii) Amend this Section 11.02(b).

No amendment of any  provision  of this  Agreement  relating to the Agent or the
Collateral Agent shall be effective  without the written consent of the Agent or
the Collateral Agent, as applicable.

          SECTION 11.03. GOVERNING LAW AND JURISDICTION.  THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS  SHALL BE CONSTRUED IN ACCORDANCE  WITH AND GOVERNED BY THE
INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY CONFLICTS OF
LAWS PRINCIPLES.  THE BORROWERS, THE AGENT, THE COLLATERAL AGENT AND THE LENDERS
CONSENT TO THE JURISDICTION OF ANY LOCAL,  STATE OR FEDERAL COURT LOCATED IN THE
CITY AND STATE OF NEW YORK AND WAIVE ANY OBJECTION RELATING TO IMPROPER VENUE OR
FORUM NON CONVENIENCE TO THE CONDUCT OF ANY PROCEEDING BY SUCH COURT.

          SECTION  11.04.  Expenses.  The Borrowers will pay, and have joint and
several  liability  for,  all  documented  out-of-pocket   third-party  expenses
(including  in each case all  reasonable  attorneys'  and  paralegals'  fees and
related expenses and costs), (i) incurred by the Agent, the Collateral Agent and
the  Documentation  Agent in connection  with the  negotiation,  preparation and
execution of the Loan Documents  (whether or not the  transactions  contemplated
hereby shall be consummated),  subject, however, to the limitations set in those
certain letters dated September 25, 1998 between KMC Holdings and the Agent, and
KMC Holdings and the Documentation  Agent, with respect to the fees and expenses
of counsel  for the Agent and the  Documentation  Agent,  (ii)  incurred  by the
Agents,  in connection with the  administration  of the Loan Documents,  and the
creation,  perfection,  priority and protection of the Liens in the  Collateral,
and (iii) incurred by any Agent or any Lender in connection with the enforcement
of the rights of any Agent or any Lender in connection with this Agreement,  any
other Loan Documents or the Collateral,  or any restructuring or workout of this
Agreement or the other Loan Documents.

          SECTION 11.05. Equitable Relief. Each Borrower recognizes that, in the
event  such  Borrower  fails  to  perform,  observe  or  discharge  any  of  its
obligations or liabilities under this Agreement, or any other Loan Document, any
remedy at law may prove to be  inadequate  relief to the Agent,  the  Collateral
Agent and the Lenders;  therefore,  such  Borrower  agrees that the Agent or the
Collateral  Agent,  if it so  requests,  shall  be  entitled  to  temporary  and
permanent  injunctive  relief in any such case without the  necessity of proving
actual damages.


                                       92


          SECTION  11.06.  Indemnification;  Limitation  of  Liability.  (a) The
Borrowers  jointly and severally  agree to protect,  indemnify and hold harmless
the  Agent,  the  Collateral  Agent  each  Lender  and each of their  respective
officers, affiliates, directors, employees, attorneys, accountants, consultants,
representatives  and agents  (collectively  called the  "Indemnitees")  from and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
actions, judgments, suits, claims, costs, expenses and disbursements (including,
without limitation,  payment by the Agent, the Collateral Agent or any Lender of
any  obligations  due or past due under any  contract or  agreement to which any
Borrower  is or  becomes a party) of any kind or nature  whatsoever  (including,
without limitation, the fees and disbursements of counsel for and consultants of
such  Indemnitees  in  connection  with  any  investigative,  administrative  or
judicial proceeding, whether or not such Indemnitees shall be designated a party
thereto),  which may be  imposed  on,  incurred  by, or  asserted  against  such
Indemnitees (whether direct, indirect, or consequential and whether based on any
federal  or  state  laws or  other  statutory  regulations,  including,  without
limitation, securities, environmental and commercial laws and regulations, under
common law or at  equitable  cause or on  contract or  otherwise)  in any manner
relating to or arising out of this Agreement or any of the other Loan Documents,
or any act, event or transaction related or attendant thereto, the agreements of
the Agent, the Collateral Agent or the Lenders contained  herein,  the making of
Loans,  the management of such Loans or the Collateral  (including any liability
under  Environmental  Laws) or the use or intended  use of the  proceeds of such
Loans hereunder  (collectively,  the "Indemnified  Matters");  provided that the
Borrowers shall not have any obligation to any Indemnitee hereunder with respect
to Indemnified  Matters  caused by or resulting  from the willful  misconduct or
gross  negligence of such Indemnitee;  provided,  further that no Borrower shall
have any obligation to any  Indemnitee  hereunder with respect to taxes that are
imposed on the net income of any  Indemnitee or any franchise or doing  business
taxes  imposed  on any  Indemnitee.  To  the  extent  that  the  undertaking  to
indemnify,  pay and hold  harmless  set forth in the  preceding  sentence may be
unenforceable because it is violative of any law or public policy, the Borrowers
shall contribute the maximum portion which they are permitted to pay and satisfy
under applicable law, to the payment and satisfaction of all Indemnified Matters
incurred by the Indemnitees.

          (b) To the extent permitted by applicable law, no claim may be made by
the Borrowers or any other Person against the Agent,  the Collateral  Agent, any
Lender or any of their respective affiliates,  directors,  officers,  employees,
agents, attorneys, accountants,  representatives or consultants for any special,
indirect,  consequential  or punitive damages in respect of any claim for breach
of contract or any other  theory of  liability  arising out of or related to the
transactions  contemplated by any of the Loan Documents or any act,  omission or
event occurring in connection therewith; and the Borrowers hereby waive, release
and agree not to sue upon any claim for any such damages, whether or not accrued
and whether or not known or suspected to exist in its favor.

          SECTION 11.07.  Survival of Representations  and Warranties,  etc. All
warranties and  representations  made by any Borrower in any Loan Document shall
survive  the  execution  and  delivery  of this  Agreement  and the  other  Loan
Documents and the making and repayment of the Obligations.  The  confidentiality
obligations of each Borrower in Section 11.16, the  indemnification  obligations
of each  Borrower  in Section  11.06,  and to the extent the second  sentence of
Section  11.13 is  applicable,  all  covenants  of each  Borrower,  survive  the
repayment of the Obligations.

                                       93


          SECTION 11.08. Successors and Assigns; Assignments; Participations.

          (a) General.  The terms and provisions of the Loan Documents  shall be
binding  upon  and  inure  to the  benefit  of the  Borrowers,  the  Agent,  the
Collateral  Agent and the Lenders and their  respective  successors and assigns,
except  that (i) no  Borrower  shall  have any  right to  assign  its  rights or
obligations  under the Loan Documents and (ii) any assignment by any Lender must
be made in compliance with  subsection (c) below.  With respect to any Borrower,
successors and assigns shall include, without limitation,  any receiver, trustee
or debtor-in-possession of or for such Borrower.  Notwithstanding the foregoing,
any Lender may at any time,  without the consent of the  Borrowers or the Agent,
assign all or any portion of its rights under this  Agreement and its Notes to a
Federal Reserve Bank or to an affiliate of such Lender; provided,  however, that
no such  assignment  shall release the  transferor  Lender from its  obligations
hereunder.  The Agent shall be entitled to utilize its Register to determine the
payee of any Note for all purposes hereof. Any request,  authority or consent of
any Person,  who at the time of making such request or giving such  authority or
consent  is the  holder of any Note,  shall be  conclusive  and  binding  on any
subsequent  holder,  transferee or assignee of such Note or of any Note or Notes
issued in exchange therefor.

          (b) Participations.

               (i) Subject to the terms set forth in this Section 11.08(b),  any
          Lender may, in the ordinary  course of its business and in  accordance
          with  applicable  law,  at any time sell to one or more banks or other
          entities ("Participants") participating interests in any Loan owing to
          such Lender,  any Note held by such  Lender,  any  Commitment  of such
          Lender or any other  interest of such Lender under the Loan  Documents
          on a pro rata or non-pro rata basis in an aggregate  principal  amount
          of at least  $5,000,000.  Notice  of such  participation  to the Agent
          shall be required prior to any participation  becoming  effective with
          respect  to a  Participant  which  is  not a  Lender  or an  Affiliate
          thereof.  In the event of any such  sale by a Lender of  participating
          interests to a Participant,  such Lender's  obligations under the Loan
          Documents  shall remain  unchanged,  such Lender  shall remain  solely
          responsible  to the other parties  hereto for the  performance of such
          obligations,  such Lender shall remain the holder of any such Note for
          all  purposes  under the Loan  Documents,  such Lender shall be solely
          responsible  for any  withholding  taxes or any  filing  or  reporting
          requirements in connection therewith relating to such Participant, all
          amounts  payable  by the  Borrowers  under  this  Agreement  shall  be
          determined  as  if  such  Lender  had  not  sold  such   participating
          interests,  and the  Borrowers  and the Agent  shall  continue to deal
          solely and directly with such Lender in connection  with such Lender's
          rights and  obligations  under the Loan  Documents  except  that,  for
          purposes of Section 2.13 hereof, the Participants shall be entitled to
          the same rights as if they were Lenders,  provided that no Participant
          shall be entitled to receive  any greater  amount  pursuant to Section
          2.13 than such Lender  would have been  entitled to receive in respect
          of the amount of the participation transferred to such Participant had
          no transfer occurred.

                                       94


               (ii) Each Lender shall retain the sole right to approve,  without
          the consent of any Participant, any amendment,  modification or waiver
          of any  provision  of the Loan  Documents  other  than any  amendment,
          modification or waiver with respect to any Loan or Commitment in which
          such Participant has an interest which forgives principal, interest or
          fees or reduces  the  interest  rate or fees  payable  pursuant to the
          terms of this  Agreement  with respect to any such Loan or Commitment,
          postpones  any  date  fixed  for any  regularly-scheduled  payment  of
          principal of, or interest or fees on, any such Loan or Commitment,  or
          releases all or substantially all of the Collateral,  if any, securing
          any such Loan.

               (iii) The Borrowers agree that each  Participant  shall be deemed
          to have the right of setoff provided in Section 9.09 hereof in respect
          to  its  participating  interest  in  amounts  owing  under  the  Loan
          Documents  to the same  extent as if the  amount of its  participating
          interest  were  owing  directly  to  it as a  Lender  under  the  Loan
          Documents,  provided that each Lender shall retain the right of setoff
          provided  in  Section  9.09  hereof  with  respect  to the  amount  of
          participating  interests sold to each Participant except to the extent
          such Participant  exercises its right of setoff.  The Lenders agree to
          share with each Participant,  and each Participant,  by exercising the
          right of setoff provided in Section 9.09 hereof,  agrees to share with
          each Lender, any amount received pursuant to the exercise of its right
          of setoff,  such amounts to be shared in accordance  with Section 9.09
          as if each Participant were a Lender.

          (c)  Assignments.

               (i) Any Lender may, in the ordinary course of its business and in
          accordance  with  applicable  law,  at any time  assign to one or more
          banks or other entities  ("Purchasers") all or a portion of its rights
          and obligations under this Agreement  (including,  without limitation,
          its Commitment and the Loans owing to it hereunder) in accordance with
          the provisions of this Section 11.08(c). Each assignment shall be of a
          constant,  and  not a  varying,  ratable  percentage  of  all  of  the
          assigning  Lender's rights and obligations under this Agreement.  Such
          assignment  shall be evidenced by an Assignment  Agreement in form and
          substance  reasonably  satisfactory  to the  Agent  and  shall  not be
          permitted  hereunder  unless such assignment is either for all of such
          Lender's rights and obligations under the Loan Documents or, for Loans
          and Commitments in an aggregate  principal  amount equal to the lesser
          of  $5,000,000  (which  minimum  amount may be waived by the Requisite
          Lenders  after  the   occurrence  of  a  Default)  and  such  Lender's
          Commitment Amount.

               (ii) Upon (i) delivery to the Agent of a notice of  assignment (a
          "Notice of Assignment"), together with any consent required hereunder,
          and  (ii)  payment  of a  $3,500  processing  fee  to  the  Agent  for
          processing  such assignment if such assignment is to a Person which is
          not an affiliate of the assigning Lender, such assignment shall become
          effective  on  the  effective   date   specified  in  such  Notice  of
          Assignment.  The assigning  Lender shall be obligated to reimburse the


                                       95


          Agent for all other costs and expenses associated with the preparation
          and execution of such assignment (including reasonable attorneys' fees
          arising out of such preparation and execution of such assignment). The
          Notice of Assignment shall contain a  representation  by the Purchaser
          to the effect that none of the consideration used to make the purchase
          of the Commitment and Loans under the applicable  assignment agreement
          are "plan  assets"  as  defined  under  ERISA and that the  rights and
          interests of the Purchaser in and under the Loan Documents will not be
          "plan  assets" under ERISA.  On and after the  effective  date of such
          assignment,  such  Purchaser,  if not already a Lender,  shall for all
          purposes  be a  Lender  party to this  Agreement  and any  other  Loan
          Documents  executed  by the  Lenders and shall have all the rights and
          obligations of a Lender under the Loan  Documents,  to the same extent
          as if it were an  original  party  hereto,  and no further  consent or
          action by the Borrowers, the Lenders or the Agent shall be required to
          release the  transferor  Lender with respect to the  percentage of the
          aggregate  Commitment and Loans assigned to such  Purchaser.  Upon the
          consummation of any assignment to a Purchaser pursuant to this Section
          11.08(c)(ii), the transferor Lender, the Agent and the Borrowers shall
          make appropriate  arrangements so that replacement Notes are issued to
          such transferor  Lender and new Notes or, as appropriate,  replacement
          Notes, are issued to such Purchaser, in each case in principal amounts
          reflecting their  Commitment and their Loans, as adjusted  pursuant to
          such assignment.

               (iii) The Agent  shall  maintain  at its  address  referred to in
          Section 11.01 a copy of each  assignment  delivered to and accepted by
          it pursuant to this Section 11.08 and a register (the  "Register") for
          the  recordation  of the names and  addresses  of the  Lenders and the
          Commitment of and principal  amount of the Loans owing to, each Lender
          from time to time and whether such Lender is an original Lender or the
          assignee  of  another  Lender  pursuant  to an  assignment  under this
          Section  11.08.  The entries in the Register  shall be conclusive  and
          binding for all purposes,  absent manifest  error,  and the Borrowers,
          the Agent and the Lenders may treat each Person whose name is recorded
          in the  Register  as a  Lender  hereunder  for  all  purposes  of this
          Agreement.  The Register  shall be  available  for  inspection  by the
          Borrowers or any Lender at any  reasonable  time and from time to time
          upon reasonable prior notice.

          SECTION 11.09. Severability. In case any one or more of the provisions
contained in this Agreement or any other Loan Document shall be invalid, illegal
or unenforceable in any respect,  the validity,  legality and  enforceability of
the remaining  provisions  contained  herein and therein shall not in any way be
affected or impaired thereby.

          SECTION 11.10. Cover Page, Table of Contents and Section Headings. The
cover  page,  Table  of  Contents  and  section  headings  used  herein  are for
convenience  of reference  only,  are not part of this  Agreement and are not to
affect the construction of or be taken into  consideration in interpreting  this
Agreement.

          SECTION  11.11.   Counterparts.   This  Agreement  may  be  signed  in
counterparts  with the same effect as if the signatures  thereof and hereto were
upon the same instrument.


                                       96


          SECTION 11.12.  Application of Payments.  Notwithstanding any contrary
provision  contained in this  Agreement  or in any of the other Loan  Documents,
upon the  occurrence and during the  continuance  of any Event of Default,  each
Borrower  irrevocably  waives the right to direct the application of any and all
payments at any time or times hereafter received by the Agent or any Lender from
such Borrower or with respect to any of the  Collateral,  and such Borrower does
hereby  irrevocably agree that the Agent or any Lender shall have the continuing
exclusive  right to apply and reapply any and all payments  received at any time
or times hereafter, whether with respect to the Collateral or otherwise, against
the  Obligations  in such manner as the Agent or any Lender may deem  advisable,
notwithstanding  any entry by the Agent or any Lender  upon any of its books and
records, subject, however, to the provisions of Section 2.08(c).

          SECTION 11.13. Marshalling;  Payments Set Aside. Neither the Agent nor
the  Collateral  Agent shall be under any  obligation  to marshall any assets in
favor of any  Borrower or any other party or against or in payment of any or all
of the Obligations.  To the extent that any Borrower makes a payment or payments
to any Agent or any  Lender or the  Agent,  the  Collateral  Agent or any Lender
enforces its security  interests  or  exercises  its rights of setoff,  and such
payment or payments or the  proceeds of such  enforcement  or setoff or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside and/or required to be repaid to a trustee, receiver or any other party
under any bankruptcy law, state or federal law,  common law or equitable  cause,
then to the extent of such recovery,  the obligation or part thereof  originally
intended to be satisfied shall be revived and continued in full force and effect
as if such  payment  had not been made or such  enforcement  or  setoff  had not
occurred.

          SECTION  11.14.  SERVICE OF PROCESS.  EACH  BORROWER  WAIVES  PERSONAL
SERVICE OF ANY PROCESS UPON IT AND,  CONSENTS  THAT ALL SERVICE OF PROCESS SHALL
BE MADE BY REGISTERED MAIL, RETURN RECEIPT REQUESTED,  DIRECTED TO SUCH BORROWER
AT THE ADDRESS INDICATED IN SECTION 11.01 AND SERVICE SO MADE SHALL BE DEEMED TO
BE  COMPLETED  FIVE (5)  BUSINESS  DAYS AFTER  SAME  SHALL  HAVE BEEN  POSTED AS
AFORESAID.

          SECTION 11.15.  WAIVER OF JURY TRIAL, ETC. EACH OF THE BORROWERS,  THE
AGENT,  THE  COLLATERAL  AGENT AND THE  LENDERS  WAIVES ANY RIGHT TO HAVE A JURY
PARTICIPATE  IN RESOLVING ANY DISPUTE,  WHETHER  SOUNDING IN CONTRACT,  TORT, OR
OTHERWISE,  BETWEEN  THE  AGENT,  THE  COLLATERAL  AGENT OR ANY  LENDER  AND ANY
BORROWER  ARISING  OUT OF,  CONNECTED  WITH,  RELATED  TO OR  INCIDENTAL  TO THE
RELATIONSHIP  ESTABLISHED  BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT OR ANY OTHER INSTRUMENT,  DOCUMENT OR AGREEMENT  EXECUTED OR
DELIVERED IN CONNECTION THEREWITH OR THE TRANSACTIONS  RELATED THERETO.  EACH OF
THE BORROWERS, THE AGENT, THE COLLATERAL AGENT AND THE LENDERS HEREBY AGREES AND
CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED
BY COURT  TRIAL  WITHOUT  A JURY  AND  THAT ANY OF THEM MAY FILE AS AN  ORIGINAL
COUNTERPART OR A COPY OF THIS  AGREEMENT  WITH ANY COURT AS WRITTEN  EVIDENCE OF
THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

                                       97


          SECTION 11.16.  Confidentiality.  No Borrower shall at any time before
or after payment in full and  satisfaction  of all of the  Obligations,  reveal,
divulge or make known, or knowingly  permit to be so revealed,  divulged or made
known, to any Person  (including  Persons within its own organization who do not
have a definite need to know for the purpose of performance of this  Agreement),
the terms or  conditions of the Fee Letters;  provided that the foregoing  shall
not  apply  to  information  required  to be  disclosed  by  order of a court of
competent jurisdiction or in connection with any governmental  investigation (in
each case to the extent disclosure is required,  but no further) so long as such
Borrower  notifies  the Agent in  writing  of any  circumstances  of which  such
Borrower is aware that may lead to such a requirement  or order,  so as to allow
the  Agent to take  steps to  contest  such  order or  investigation;  provided,
further,  that the foregoing shall not apply to information which is required to
be  disclosed  by  such  Borrower  or   information   which  in  the  reasonable
determination  of such  Borrower is  desirable  for such  Borrower to  disclose,
pursuant  to  federal  or  state  securities  laws,  pursuant  to the  rules  or
regulations of the FCC, any PUC or other applicable  Governmental  Authority, or
to Persons who are consultants, advisors (including but not limited to attorneys
and auditors),  officers, directors or employees of such Borrower, provided that
each  such  Person  is  required  by  such  Borrower  to keep  such  information
confidential.

          SECTION 11.17.  Entire Agreement,  etc. This Agreement  (including all
schedules and exhibits  referred to herein),  the Notes, the Fee Letters and all
other Loan Documents  constitute the entire contract  between the parties hereto
with respect to the subject  matter  hereof and thereof and shall  supersede and
take the place of any other  instrument  purporting  to be an  agreement  of the
parties hereto relating to such subject matter.

          SECTION  11.18.  No  Strict  Construction.  The  parties  hereto  have
participated,  jointly in the negotiation and drafting of this Agreement. In the
event of any  ambiguity  or question of intent or  interpretation  arises,  this
Agreement  shall be construed as if drafted jointly by the parties hereto and no
presumption or burden of proof shall arise favoring or disfavoring  any party by
virtue of authorship of any provisions of this Agreement.


                                       98


          IN WITNESS  WHEREOF,  the parties hereto have caused this Agreement to
be duly executed by their duly authorized  officers as of the day and year first
above written.
