Banks shall be reduced pro rata in accordance with their  respective  Commitment
Percentages  of the  amount  specified  in such  notice  or, as the case may be,
terminated.  Promptly  after  receiving  any  notice of the  Borrower  delivered

the  substance  thereof.  No  reduction of the  Commitments  of the Banks may be

outstanding  amount of the Revolving  Credit Loans set forth on such Note Record
shall be prima facie  evidence of the principal  amount thereof owing and unpaid
to such Bank, but the failure to record, or any error in so recording,  any such
amount on such Note Record shall not limit or otherwise  affect the  obligations
of the Borrower hereunder or under any Revolving Credit Note to make payments of
principal of or interest on any Revolving Credit Note when due.

         Section 2.5.  Requests for Revolving  Credit Loans.  The Borrower shall
give to the Administrative  Agent written notice in the form of Exhibit B hereto
(or telephonic notice confirmed in a writing in the form of Exhibit B hereto) of
each Revolving Credit Loan requested  hereunder (a "Loan Request") no later than
11:00 a.m. (Boston time) at least two (2) Eurodollar  Business Days prior to the
proposed  Drawdown  Date of any  Revolving  Credit Loan.  Each such notice shall
specify (i) the principal  amount of the Revolving  Credit Loan requested,  (ii)
the proposed  Drawdown Date of such Revolving Credit Loan and (iii) the Interest
Period for such  Revolving  Credit Loan.  Promptly upon receipt of any such Loan
Request,  the  Administrative  Agent  shall  notify  each  of the  Banks  of the
substance  thereof.  Each Loan Request shall be  irrevocable  and binding on the
Borrower and shall  obligate the  Borrower to accept the  Revolving  Credit Loan
requested from the Banks on the proposed  Drawdown Date. Each Loan Request for a
Revolving  Credit Loan shall be in a minimum amount of $3,000,000 or an integral
multiple of $250,000 in excess thereof.

         Section 2.6.  Funds for Revolving Credit Loans.

         (a)    Not later than 11:00 a.m. (Boston time) on the proposed Drawdown
Date of any Revolving  Credit  Loans,  each of the Banks,  severally,  will make
available  to the  Administrative  Agent,  at its head  office,  in  immediately
available funds, the amount of such Bank's  Commitment  Percentage of the amount
of the requested Revolving Credit Loans. Upon receipt from each Bank of such
amount,  and upon receipt of the documents  required by Sections 8 and 9 and the
satisfaction  of  the  other  conditions  set  forth  therein,   to  the  extent
applicable,  the  Administrative  Agent will make the  aggregate  amount of such
Revolving Credit Loans available to the Borrower.  The failure or refusal of any
Bank to make available to the Administrative  Agent at the aforesaid time on any
Drawdown Date the amount of its Commitment Percentage of the requested Revolving
Credit  Loans  shall not  relieve  any other  Bank from its  several  obligation
hereunder  to make  available  to the  Administrative  Agent  the  amount of its
Commitment Percentage of any requested Revolving Credit Loans.

         (b)    The Administrative Agent may (unless notified to the contrary by
any Bank prior to a Drawdown  Date) assume that each Bank has made  available to
the  Administrative  Agent on such  Drawdown  Date  the  amount  of such  Bank's
Commitment  Percentage of the Revolving Credit Loans to be made on such Drawdown
Date,  and the  Administrative  Agent may (but it shall not be required  to), in
reliance upon such  assumption,  make available to the Borrower a  corresponding
amount.  If any Bank makes  available  to the  Administrative  Agent such amount
advanced by the  Administrative  Agent on a date after such Drawdown Date,  such
Bank  shall pay to the  Administrative  Agent on  demand an amount  equal to the
product of (i) the average  computed for the period  referred to in clause (iii)
below, of the weighted  average interest rate paid by the  Administrative  Agent
for federal funds acquired by the Administrative  Agent during each day included
in such period, times (ii) the amount equal to such Bank's Commitment






                                     - 13 -


Percentage of such Revolving Credit Loans, times (iii) a fraction, the numerator
of which is the number of days that elapse from and including such Drawdown Date
to the date on which the amount of such  Bank's  Commitment  Percentage  of such
Revolving Credit Loans shall become immediately  available to the Administrative
Agent,  and the  denominator  of  which is 365.  If the  amount  of such  Bank's
Commitment  Percentage of such  Revolving  Credit Loans is not made available to
the  Administrative  Agent by such Bank within three (3)  Business  Days of such
Drawdown Date, the Administrative Agent shall be entitled to recover such amount
from the  Borrower  on  demand,  with  interest  thereon  at the rate per  annum
applicable to the Revolving Credit Loans made on such Drawdown Date. A statement
of the  Administrative  Agent  submitted to any Bank with respect to any amounts
owing under this  paragraph  shall be prima facie evidence of the amount due and
owing to the Administrative Agent by such Bank.


         Section 2.7.  Mandatory  Repayments of Loans. The Borrower  promises to
pay the outstanding amount of all Loans on the Maturity Date. In addition, if at
any time the outstanding amount of the Loans exceeds the Total Commitment,  then
the  Borrower  shall   immediately   pay  the  amount  of  such  excess  to  the
Administrative Agent for application to the Loans.

         Section 2.8. Optional  Repayments of Loans. The Borrower shall have the
right, at its election, to repay the outstanding amount of any Loans, as a whole
or in part, at any time without penalty or premium; provided that in the case of
any full or partial prepayment of the outstanding amount of any Revolving Credit
Loans prior to the end of the Interest Period applicable  thereto,  the Borrower
shall be obligated to reimburse the Banks in respect thereof pursuant to Section
3.3. The Borrower shall give the Administrative  Agent, no later than 11:00 a.m.
(Boston time), at least two (2) Eurodollar Business Days' notice of any proposed
repayment of Revolving  Credit Loans,  in each case specifying the proposed date
of  repayment  and the  principal  amount to be paid,  which  notice,  if not in
writing,  shall be promptly  confirmed in writing.  Each such partial payment of
Revolving Credit Loans shall be in a minimum amount of $3,000,000 or an integral
multiple of $250,000 in excess thereof. Each partial payment of Swing Line Loans
shall be in an amount of $10,000 or an integral multiple thereof. Each repayment
pursuant  to this  Section  2.8 shall be  accompanied  by the payment of accrued
interest on the principal repaid to the date of payment.  Each partial repayment
of Revolving Credit Loans shall be allocated among the Banks, in proportion,  as
nearly as practicable,  to the respective unpaid principal amount of each Bank's
Revolving  Credit Note, with  adjustments to the extent  practicable to equalize
any prior  repayments not exactly in proportion,  and each partial  repayment of
Swing Line Loans shall be allocated as described in Section 2.9(d) below.

     Section 2.9.  The Swing Line Loans.

     (a) Subject to the terms and conditions  hereinafter set forth, upon notice
by the Borrower made to the Swing Line Bank in accordance  with Section  2.9(b),
the Swing  Line Bank  agrees to lend to the  Borrower  Swing  Line  Loans on any
Business  Day from the  Closing  Date until the  Maturity  Date in an  aggregate
principal  amount  not to  exceed  $20,000,000  (the  "Maximum  Swing  Line Loan
Amount").  Each Swing Line Loan shall be in a minimum amount equal to $10,000 or
an integral  multiple  thereof.  Notwithstanding  any other  provisions  of this
Agreement  and in  addition to the limit set forth  above,  at no time shall the
aggregate  principal  amount  of all  outstanding  Swing  Line  Loans  plus  the
aggregate  principal amount of all Revolving Credit Loans outstanding exceed the
Total Commitment then in effect;






                                     - 14 -


provided  however  that  subject to the  limitations  set forth in this  Section
2.9(a) from time to time the sum of the aggregate  outstanding  Swing Line Loans
plus all  outstanding  Revolving  Credit  Loans  made by  BankBoston  may exceed
BankBoston's Commitment Percentage of the Total Commitment then in effect.

     (b) Notice of Borrowing.  When the Borrower  desires the Swing Line Bank to
make a Swing Line Loan, it shall send to the Administrative  Agent and the Swing
Line Bank a Loan  Request,  which  shall set forth the  principal  amount of the
proposed  Swing  Line Loan and the date on which the  proposed  Swing  Line Loan
would mature (the "Swing Line Loan Maturity  Date"),  which shall in no event be
later than the  Maturity  Date.  Each such Loan  Request must be received by the
Swing  Line Bank not later  than  12:00  p.m.  (Boston  time) on the date of the
proposed  borrowing.  Each Loan Request shall be irrevocable  and binding on the
Borrower and shall  obligate the Borrower to borrow the Swing Line Loan from the
Swing Line Bank on the proposed Drawdown Date thereof.  Upon satisfaction of the
applicable conditions set forth in this Agreement, on the proposed Drawdown Date
the Swing Line Bank shall make the Swing Line Loan  available to the Borrower no
later than 3:00 p.m.  (Boston  time) on the proposed  Drawdown Date by crediting
the  amount of the Swing Line Loan to the  Borrower's  account  maintained  with
LaSalle National Bank, Chicago, ABA #071-000-505, Account #22-2813-9 in the name
of United States Cellular  Corporation;  provided that the Swing Line Bank shall
not advance any Swing Line Loans after it has  received  notice from any Bank or
the  Administrative  Agent that a Default or Event of Default has  occurred  and
stating  that no new Swing Line Loans are to be made until such Default or Event
of Default has been cured or waived in  accordance  with the  provisions of this
Credit  Agreement.  The Swing Line Bank shall not be obligated to make any Swing
Line Loans at any time when any Bank is a Delinquent  Bank unless the Swing Line
Bank has entered into  arrangements  satisfactory  to it to eliminate  the Swing
Line  Bank's  risk with  respect  to such  Delinquent  Bank,  including  by cash
collateralizing such Delinquent Bank's Commitment  Percentage of the outstanding
Swing Line Loans and any such additional Swing Line Loans to be made.

     (c) Interest on Swing Line Loans. The outstanding amount of each Swing Line
Loan shall bear  interest from the Drawdown Date thereof until repaid in full at
the rate per annum  equal to the Base  Rate  from  time to time in  effect  less
one-half of one percent (0.50%),  except as otherwise  provided in Section 3.11,
and shall be paid quarterly in arrears on the last day of each calendar quarter.

     (d)  Repayment  of  Swing  Line  Loans.   The  Borrower  shall  repay  each
outstanding  Swing  Line Loan on or prior to the Swing Line Loan  Maturity  Date
relating  thereto.  Upon  notice by the  Swing  Line  Bank on any  Business  Day
(whether  before or on the Maturity  Date),  each of the Banks hereby  agrees to
make  payments to the  Administrative  Agent,  for the account of the Swing Line
Bank, on the next  succeeding  Business Day following such notice,  in an amount
equal to such Bank's Commitment  Percentage of the aggregate amount of all Swing
Line Loans outstanding.  The parties hereto agree that such payments made to the
Administrative  Agent  for the pro rata  account  of the Swing  Line Bank  shall
constitute  Revolving Credit Loans made to the Borrower  hereunder,  except that
such  Loans  shall  bear   interest  from  the  date  of  such  payment  to  the
Administrative  Agent  until  repaid in full at the per annum  rate equal to the
Base Rate from time to time in effect  less  one-half  of one  percent  (0.50%),
except as otherwise  provided for in Section 3.11. The proceeds thereof shall be
applied  directly  to the Swing  Line Bank to repay the Swing Line Bank for such
outstanding Swing Line Loans. Each Bank hereby absolutely,  unconditionally  and
irrevocably  agrees to make such Revolving  Credit Loans upon one Business Day's
notice as set forth above,  notwithstanding (i) that the amount of such Loan may
not comply with the applicable minimums






                                     - 15 -


set  forth  in  Section  2.5,  (ii)  the  failure  of the  Borrower  to meet the
conditions  set forth in Sections 8 or 9, (iii) the occurrence or continuance of
a Default or an Event of Default hereunder,  (iv) the date of such Loan, and (v)
the  Total  Commitment  in  effect  at  such  time.  In  the  event  that  it is
impracticable  for such  amounts to be paid to the  Administrative  Agent or the
Swing  Line  Bank or such Loan to be made for any  reason on the date  otherwise
required above,  then each Bank hereby agrees that it shall  forthwith  purchase
(as of the date such  payment and such Loan would have been made,  but  adjusted
for any payments  received  from the Borrower on or after such date and prior to
such  purchase)  from the Swing Line Bank, and the Swing Line Bank shall sell to
each Bank, such  participations  in the Swing Line Loans  (including all accrued
and unpaid  interest  thereon)  outstanding  as shall be  necessary to cause the
Banks to share in such  Swing  Line  Loans  pro rata  based on their  respective
Commitment   Percentages  (without  regard  to  any  termination  of  the  Total
Commitment)  by making  available to the Swing Line Bank an amount equal to such
Bank's  participation  in the Swing Line Loans;  provided  that (x) all interest
payable on the Swing Line Loans  shall be for the account of the Swing Line Bank
as a funding and  administrative  fee until the date as of which the  respective
participation  is  purchased,   and  (y)  at  the  time  any  purchase  of  such
participation is actually made, the purchasing Bank shall be required to pay the
Swing  Line  Bank  interest  on the  principal  amount of the  participation  so
purchased  for each day from and  including  the date such Loan would  otherwise
have been made until the date of payment for such  participation  at the rate of
interest equal to the Base Rate in effect during such period.



         (e) The Swing Line Note.  The  obligation  of the Borrower to repay the
Swing Line Loans made pursuant to this Agreement and to pay interest  thereon as
set forth in this  Agreement  shall be  evidenced  by a  promissory  note of the
Borrower with  appropriate  insertions  substantially in the form of Exhibit A-2
attached  hereto (the "Swing Line Note"),  dated the Closing Date and payable to
the order of the Swing Line Bank in a principal  amount  stated to be the lesser
of (i) the  Maximum  Swing Line Loan  Amount,  or (ii) the  aggregate  principal
amount of Swing  Line  Loans at any time  advanced  by the  Swing  Line Bank and
outstanding thereunder.  The Borrower irrevocably authorizes the Swing Line Bank
to make or cause to be made,  at or about the time of the  Drawdown  Date of any
Swing  Line Loan or at the time of receipt of any  payment of  principal  on the
Swing Line Note,  an  appropriate  notation on the Note Record of the Swing Line
Note  reflecting  the making of such Swing Line Loan or (as the case may be) the
receipt  of such  payment.  The  outstanding  amount of the Swing Line Loans set
forth on such Note Record shall be prima facie evidence of the principal  amount
thereof owing and unpaid to the Swing Line Bank,  but the failure to record,  or
any error in so  recording,  any such amount on such Note Record shall not limit
or  otherwise  affect  the  actual  amount of the  obligations  of the  Borrower
hereunder  or under the Swing  Line Note to make  payments  of  principal  of or
interest on the Swing Line Note when due.

         Section 3.        INTEREST; CERTAIN GENERAL PROVISIONS.
                           --------  ------- ------- ----------

         Section 3.1. Interest on Loans; Payment.  Except as otherwise increased
pursuant to Section 3.11 hereof, the outstanding amount of each Revolving Credit
Loan shall bear interest during each Interest Period relating  thereto at a rate
per annum equal to the Eurodollar  Rate determined for such Interest Period plus
the applicable  Margin Percentage as in effect on the first day of such Interest
Period. The Borrower absolutely and unconditionally  promises to pay interest on
each Revolving Credit Loan in arrears on each Interest Payment Date with respect
thereto.







                                     - 16 -


         Section 3.2.  Interest  Period  Options.  Upon notice (a  "Continuation
Request")  given to the  Administrative  Agent no later than 11:00 a.m.  (Boston
time) at least two (2)  Eurodollar  Business Days' prior to the expiration of an
Interest Period  applicable to any Revolving Credit Loan, the Borrower may elect
to  continue  such  Revolving  Credit  Loan  upon  the  expiration  of the  then
applicable Interest Period for another Interest Period of the duration specified
in such notice;  provided that no Revolving  Credit Loan may be continued for an
Interest Period in excess of seven (7) days when any Default or Event of Default
has occurred and is continuing; provided further that the Revolving Credit Loans
to which a particular Interest Period applies shall be in an aggregate principal
amount of $3,000,000 or an integral multiple of $250,000 in excess thereof. Each
continuation of a Revolving Credit Loan hereunder shall be allocated between the
Banks in  proportion,  as  nearly  as  practicable,  to such  Bank's  Commitment
Percentage,  with  adjustments  to the extent  practicable to equalize any prior
continuations not exactly in proportion.

         Section 3.3. Indemnity.  The Borrower agrees to indemnify each Bank and
to hold each Bank  harmless  from any loss or expense that such Bank may sustain
or incur as a  consequence  of (a)  default  by the  Borrower  in payment of the
principal amount of or interest on any Loans, including any such loss or expense
arising from interest or fees payable by such Bank to lenders of funds  obtained
by it in order to maintain  its Loans,  (b) default by the  Borrower in making a
borrowing  after the  Borrower  has  given  (or is deemed to have  given) a Loan
Request or a Continuation  Request in accordance  with Sections 2.5 or 3.2 other
than as a result of a default by any Bank,  (c) the  making of any  payment of a
Revolving  Credit  Loan  on a day  that is not the  last  day of the  applicable
Interest Period with respect thereto,  including interest or fees payable by any
Bank to lenders of funds  obtained by it in order to maintain any such Revolving
Credit Loan, to the extent not off-set by income  derived from the  redeployment
of such funds,  or (d) default by the Borrower in making any repayment of a Loan
after the Borrower  has given a notice in  accordance  with  Section  2.8.  This
covenant shall survive the  termination of this Credit  Agreement and payment of
the Notes.

         Section 3.4. Funds for Payments. Except as set forth in Section 2.9(d),
all payments of principal,  interest, and the Facility Fee and any other amounts
due  hereunder  or under any of the other  Loan  Documents  shall be made by the
Borrower to the Administrative  Agent at the Administrative  Agent's head office
at 100 Federal Street, Boston,  Massachusetts 02110 or at such other location in
the Boston,  Massachusetts area that the  Administrative  Agent may from time to
time designate, in each case in immediately available funds. All payments by the
Borrower  hereunder  and  under any of the other  Loan  Documents  shall be made
without setoff or counterclaim  and free and clear of and without  deduction for
any taxes, levies,  imposts,  duties,  charges, fees, deductions,  withholdings,
compulsory  loans,  restrictions  or  conditions  of any nature now or hereafter
imposed or levied by any  jurisdiction or any political  subdivision  thereof or
taxing or other  authority  therein  unless the  Borrower is compelled by law to
make such deduction or  withholding.  If any such obligation is imposed upon the
Borrower with respect to any amount  payable by it hereunder or under any of the
other Loan Documents, the Borrower will pay to the Administrative Agent, for the
account of the Banks or (as the case may be) the  Administrative  Agent,  on the
date on which such amount is due and payable  hereunder or under such other Loan
Document,  such additional amount in Dollars as shall be necessary to enable the
Banks or the Administrative Agent to receive the same net amount which the Banks
or the  Administrative  Agent  would have  received on such due date had no such
obligation been imposed upon the Borrower. The Borrower will deliver promptly to
the  Administrative  Agent certificates or other valid vouchers for all taxes or
other charges deducted






                                     - 17 -


from or paid with respect to payments  made by the  Borrower  hereunder or under
such other Loan Document.  The Borrower may, within 90 days of the imposition of
any such  obligation  by any Bank,  by notice in writing  to the  Administrative
Agent and such Bank,  (a) require  such Bank that  imposed  such  obligation  to
cooperate with the Borrower in obtaining an Eligible  Assignee  satisfactory  to
the  Administrative  Agent as a replacement  bank for such Bank and in assigning
such Bank's  interest  hereunder  and under its Note to such  Eligible  Assignee
subject to the terms, conditions, and procedures of Section 15, or (b) repay all
amounts  owed to such Bank,  terminate  such  Bank's  Commitment  and reduce the
aggregate  of the  Commitments  under the Credit  Agreement  by a  corresponding
amount.  Each Bank that is not  incorporated  or organized under the laws of the
United States of America or a state  thereof or the District of Columbia  agrees
that, on an annual basis, it will deliver to the Borrower and the Administrative
Agent two duly completed  copies of United States Internal  Revenue Service Form
1001 or 4224 or successor  applicable  form,  as the case may be,  certifying in
each case that such Bank is  entitled  to receive  payments  under  this  Credit
Agreement and the Note payable to it,  without  deduction or  withholding of any
United States federal income taxes.

         Section  3.5.  Computations.   All  computations  of  interest  on  the
Revolving Credit Loans and the Facility Fee shall be based on a 360 day year and
paid for the actual number of days elapsed.  All computations of interest on the
Swing Line Loan shall be based on a 365 day year and paid for the actual  number
of days elapsed.  Except as otherwise  specifically provided herein,  whenever a
payment  hereunder or under any of the other Loan Documents becomes due on a day
that is not a Business  Day, the due date for such payment  shall be extended to
the next  succeeding  Business  Day,  and  interest  shall  accrue  during  such
extension.  The outstanding amount of the Loans as reflected on the Note Records
from time to time shall be considered  conclusive  and binding  absent  manifest
mathematical error on the Borrower unless within thirty (30) Business Days after
receipt  of any notice by the  Administrative  Agent or any of the Banks of such
outstanding  amount, the Borrower shall notify the Administrative  Agent or such
Bank to the contrary.

         Section 3.6.  Inability to Determine  Eurodollar Rate. In the event the
Administrative Agent shall determine that adequate and reasonable methods do not
exist for  ascertaining  the Eurodollar Rate that would otherwise  determine the
rate of interest to be applicable during any Interest Period, the Administrative
Agent shall  forthwith give telex notice of such  determination  (which shall be
conclusive  and  binding  on the  Borrower)  to the  Borrower  at least  one (1)
Business Day before the first day of such Interest  Period.  In such event,  (a)
any Loan  Request  or  Continuation  Request  with  respect  to  Loans  shall be
automatically withdrawn, (b) the Borrowers and the Banks shall negotiate in good
faith to agree on an alternative interest rate which is reasonably equivalent to
the Eurodollar Rate;  provided that if the Borrowers and the Banks are unable to
agree  on such  alternative  interest  rate  prior  to the  last day of the then
current Interest Period,  each Revolving Credit Loan then outstanding will as of
the last day of the then current  Interest  Period bear  interest at a per annum
rate  equal to the Base Rate in effect  from time to time  payable in arrears on
the last day of each fiscal  quarter of the Borrower and (c) the  obligations of
the Banks to make additional Revolving Credit Loans shall be suspended until the
Administrative  Agent  determines  that the  circumstances  giving  rise to such
suspension no longer exist,  whereupon the Administrative  Agent shall so notify
the Borrower and the Banks.








                                     - 18 -


         Section 3.7.  Illegality.  Notwithstanding any other provisions herein,
if any introduction of or change in any law, regulation,  treaty or directive or
in the  interpretation  or  application  thereof shall make it unlawful,  or any
central bank or other governmental  authority having  jurisdiction over any Bank
or its Eurodollar Lending Office shall assert that it is unlawful, for such Bank
or its  Eurodollar  Lending  Office to make or maintain Loans that bear interest
calculated by reference to the Eurodollar  Rate,  (a) such Bank shall  forthwith
give notice by telefax of such  circumstances,  confirmed in a writing delivered
to the Borrower by courier or postal service (which notice shall be withdrawn by
such Bank when such Bank shall  reasonably  determine that it shall no longer be
illegal for such Bank or its Eurodollar  Lending Office to make or maintain such
Loans),  (b) the  commitment of such Bank to make or maintain  Revolving  Credit
Loans shall  forthwith be cancelled and (c) such Bank's  Revolving  Credit Loans
then  outstanding,  if  any,  shall  be  converted  automatically  on  the  next
succeeding last day of each Interest Period  applicable to such Revolving Credit
Loans or within  such  earlier  period as may be  required by law to Loans which
bear interest at a per annum rate equal to an alternative interest rate which is
reasonably equivalent to the Eurodollar Rate upon which the Administrative Agent
and the Banks may in good faith  agree;  provided  that if the  Borrower and the
Banks are unable to agree on such  alternative  interest rate,  such Loans shall
bear  interest at a per annum rate equal to the Base Rate in effect from time to
time payable in arrears on the last day of each fiscal  quarter of the Borrower.
The Borrower agrees promptly to pay the Administrative  Agent for the account of
each Bank,  upon demand by the  Administrative  Agent,  any  additional  amounts
necessary to compensate  the Banks for any costs incurred by the Banks in making
any  conversion in accordance  with this Section 3.7,  including any interest or
fees payable by the Banks to lenders of funds  obtained by them in order to make
or  maintain  their Loans (the  Administrative  Agent's  written  notice of such
costs, as certified to the Borrower, to be conclusive absent manifest error).

         Section 3.8.  Additional  Costs,  Etc. If any present or future, or any
change in any  present or future,  applicable  law,  which  expression,  as used
herein, includes statutes,  rules and regulations thereunder and interpretations
thereof by any competent court or by any  governmental or other  regulatory body
or official charged with the  administration or the  interpretation  thereof and
requests, directives,  instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Bank by any central bank or other
fiscal,  monetary or other  authority  (whether or not having the force of law),
shall:

         (a)  subject any Bank to any tax,  levy,  impost,  duty,  charge,  fee,
deduction or  withholding  of any nature with respect to this Credit  Agreement,
the other Loan Documents,  such Bank's  Commitment or the Loans advanced by such
Bank  (other  than taxes based upon or measured by the income or profits of such
Bank), or

         (b)  materially  change the basis of  taxation  (except  for changes in
taxes on income or profits) of payments to any Bank of the  principal  of or the
interest  on any Loans or any other  amounts  payable  to such Bank  under  this
Credit Agreement or the other Loan Documents, or

         (c)  impose or increase or render applicable  (other than to the extent
specifically  provided  for  elsewhere  in this  Credit  Agreement)  any special
deposit, reserve,  assessment,  liquidity, or other similar requirements against
assets  held  by,  or  deposits  in or for the  account  of,  or  loans  by,  or
commitments of, or letters of credit issued by, an office of any Bank, or







                                     - 19 -


         (d)  impose  on any Bank any  other  conditions  or  requirements  with
respect to this Credit  Agreement,  the other Loan  Documents,  the Loans,  such
Bank's  Commitment,  or any  class of loans or  commitments  of which any of the
Loans or such Bank's Commitment forms a part;

and the result of any of the foregoing is

                  (i) to  increase  the  cost to any  Bank of  making,  funding,
         issuing,  renewing,  extending or maintaining  the Loans or such Bank's
         Commitment, or

                  (ii) to reduce  the  amount of  principal,  interest  or other
         amounts  payable  to such Bank  hereunder  on  account  of such  Bank's
         Commitment or the Loans, or

                  (iii) to  require  such Bank to make any  payment or to forego
         any  interest  or other  sum  payable  hereunder,  the  amount of which
         payment or foregone interest or other sum is calculated by reference to
         the gross amount of any sum receivable or deemed  received by such Bank
         from the Borrower hereunder,

then, and in each such case, the Borrower will, upon written demand made by such
Bank at any time and from time to time and as often as the occasion therefor may
arise,  pay to such  Bank  such  additional  amounts  as will be  sufficient  to
compensate such Bank for such additional  cost,  reduction,  payment or foregone
interest or other sum (after such Bank shall have  allocated the same fairly and
equitably among all customers of any class generally affected thereby); provided
that in the event that such additional  cost,  reduction,  payment,  or foregone
interest or other sum which was incurred by such Bank is  subsequently  returned
or reimbursed to such Bank,  such Bank shall return or reimburse to the Borrower
any additional  amount paid pursuant to this Section 3.8 by the Borrower to such
Bank with respect thereto.  In the event that any of the foregoing events occur,
each Bank will use its reasonable efforts to take such actions as are reasonably
feasible and  available to such Bank to decrease the  additional  costs  payable
hereunder;  provided  that no Bank shall be required to transfer any  activities
related to this  Agreement  to any  jurisdiction  in which such Bank does not at
such time regularly  conduct  ordinary  banking  operations or to a jurisdiction
which otherwise will be  disadvantageous  to such Bank. Such Bank shall give the
Borrower  written notice of any event causing such additional  cost,  reduction,
payment  or  foregone  interest  or other sum  within 90 days of the  occurrence
thereof and the Borrower  shall not be liable for any such costs  incurred prior
to the date which is 90 days prior to the date of such notice.

         Section 3.9.  Certificate.  A certificate  setting forth any additional
amounts payable  pursuant to Sections 3.7 and 3.8 and the changes as a result of
which such amounts are due and the computations in reasonable detail pursuant to
which such amounts were calculated, submitted by any Bank to the Borrower, shall
be conclusive  absent manifest error.  Upon delivery of a notice to such Bank no
more than thirty Business Days after receipt of such  certificate,  the Borrower
shall have reasonable opportunity to review and discuss such computations with a
responsible officer at such Bank.

         Section 3.10. Capital Adequacy. If any present or future, or any change
in any present or future, law, governmental rule, regulation,  policy, guideline
or  directive  (whether  or not having  the force of law) or the  interpretation
thereof  by a court or  governmental  authority  with  appropriate  jurisdiction
affects the amount of capital  required or expected to be maintained by any Bank
or any corporation controlling






                                     - 20 -


such Bank and such Bank  determines  that the amount of capital  required  to be
maintained by it or such corporation is increased by or based upon the existence
of its Commitment or the Loans made pursuant  hereto,  then such Bank may notify
the  Borrower  of such  fact.  To the  extent  that the costs of such  increased
capital  requirements  are  not  reflected  in the  rates  of  interest  payable
hereunder,  the Borrower and such Bank shall thereafter  attempt to negotiate in
good faith,  within  thirty (30) days of the day on which the Borrower  receives
such notice,  an adjustment  payable  hereunder that will adequately  compensate
such Bank in light of these  circumstances.  If the  Borrower  and such Bank are
unable to agree to such adjustment  within thirty (30) days of the date on which
the Borrower  receives such notice,  then  commencing on the date of such notice
(but  not  earlier  than  the  effective  date  of any  such  increased  capital
requirement),  the fees payable hereunder shall increase by an amount that will,
in such Bank's reasonable  determination,  provide adequate compensation to such
Bank, such amount to be conclusive and binding on the Borrower,  absent manifest
error.  Each Bank shall allocate such cost increases among its customers in good
faith and on an equitable basis.

         Section 3.11.  Interest on Overdue Amounts.  Overdue  principal and (to
the extent  permitted  by  applicable  law)  interest on the Loans and all other
overdue amounts payable hereunder or under any of the other Loan Documents shall
bear interest  compounded  daily and payable on demand at a rate per annum which
is two percent (2%) above the per annum  interest rate  otherwise  applicable to
such  Loans,  until such  amount  shall be paid in full (after as well as before
judgment).

         Section 4.        REPRESENTATIONS AND WARRANTIES.  The Borrower 
represents and warrants to the Banks as follows:

         Section 4.1.  Corporate Authority.

         (a) Incorporation; Good Standing. Each of the Borrower and its Material
Subsidiaries (i) is a corporation  duly organized,  validly existing and in good

conducted  and as  presently  contemplated,  and (iii) is in good  standing as a
foreign  corporation and is duly authorized to do business in each  jurisdiction
where  such  qualification  is  necessary  except  where (x) a failure  to be so
qualified would not have a materially adverse effect on the business,  assets or
financial   condition   of  the  Borrower  or  the  Borrower  and  its  Material
Subsidiaries,  taken  as a  whole  or the  Borrower's  ability  to  perform  the
Obligations or (y) the Borrower or such Subsidiary has applied for qualification
to do business in such jurisdiction and such application is pending.

         (b)  Authorization.  The  execution,  delivery and  performance of this
Credit  Agreement and the other Loan Documents to which the Borrower is or is to
become a party and the  transactions  contemplated  hereby and  thereby  (i) are
within the corporate  authority and legal right of the Borrower,  (ii) have been
duly authorized by all necessary  corporate  proceedings,  (iii) do not conflict
with or result in any breach or contravention of any provision of law,  statute,
rule or  regulation  to which the  Borrower is subject or any  judgment,  order,
writ, injunction,  license or permit applicable to the Borrower which would have
a materially  adverse effect on the business,  assets or financial  condition of
the Borrower or the Borrower and its Material Subsidiaries, taken as a whole and
(iv) do not conflict with any  provision of the corporate  charter or bylaws of,
or any agreement or other instrument binding upon, the Borrower.






                                     - 21 -


         (c) Enforceability. The execution and delivery of this Credit Agreement
and the other Loan  Documents  to which the  Borrower is or is to become a party
will result in valid and legally binding obligations of the Borrower enforceable
against it in accordance  with the respective  terms and  provisions  hereof and
thereof,  except  as  enforceability  is  limited  by  bankruptcy,   insolvency,
reorganization,  moratorium or other laws relating to or affecting generally the
enforcement of creditors'  rights and except to the extent that  availability of
the  remedy of  specific  performance  or  injunctive  relief is  subject to the
discretion of the court before which any proceeding therefor may be brought.

         Section  4.2.  Governmental  Approvals.  The  execution,  delivery  and
performance  by the  Borrower  of  this  Credit  Agreement  and the  other  Loan
Documents to which the Borrower is or is to become a party and the  transactions
contemplated  hereby  and  thereby do not  require  the  Borrower  to obtain the
approval  or  consent  of, to make a filing  with,  or to  perform or obtain the
performance  of any other act by or in  respect  of any  governmental  agency or
authority other than those already obtained or performed.

         Section 4.3.  Title to Properties;  Leases.  Other than as noted on the
audited  consolidated  financial statements of the Borrower and its Subsidiaries
as at the Balance Sheet Date, the Borrower and its  Subsidiaries  own all of the
assets  reflected  in the  consolidated  balance  sheet of the  Borrower and its
Subsidiaries  as at the Balance  Sheet Date or acquired  since that date (except
property  and assets sold or  otherwise  disposed of in the  ordinary  course of
business  since  that date and  except  for  defects  of title to  certain  real
property  which do not  materially  impair  the  value or  usefulness  thereof),
subject to no rights of others,  including any  mortgages,  leases,  conditional
sales  agreements,  title  retention  agreements,  liens or other  encumbrances,
except  for liens  permitted  pursuant  to Section  6.2.  The  Borrower  and its
Material Subsidiaries enjoy peaceful and undisturbed possession under all leases
under which they are operating, and all said leases are valid and subsisting and
in full force and effect except to the extent that the failure to enjoy peaceful
and  undisturbed  possession  of such  lease or the  failure of such lease to be
valid,  subsisting and in full force and effect does not have a material adverse
effect on the assets,  financial  condition  or business of the Borrower and its
Material Subsidiaries, taken as a whole.

         Section 4.4. Financial Statements.  There has been furnished to each of
the Banks a consolidated  balance sheet of the Borrower and its  Subsidiaries as
at the  Balance  Sheet  Date,  and related  consolidated  statements  of income,
retained  earnings  and cash flow for the fiscal year then ended,  certified  by
Arthur  Andersen  and  Company,  the  Borrower's  independent  certified  public
accountants.  Such balance sheet and statements of income, retained earnings and
cash flow have been prepared in accordance  with Generally  Accepted  Accounting
Principles  consistently applied and are correct and complete and fairly present
the financial condition of the Borrower and its Material  Subsidiaries as at the
close of business on the date thereof and the consolidated results of operations
for the fiscal  year then  ended.  There are no  contingent  liabilities  of the
Borrower or any of its Subsidiaries as of such date involving  material amounts,
known to the officers of the Borrower  and not  disclosed in said balance  sheet
and the related notes thereto.

         Section 4.5. No Material  Changes,  Etc.  Since the Balance  Sheet Date
there has occurred no materially  adverse  change in the financial  condition or
business of the  Borrower and its  Subsidiaries  as shown on or reflected in the
consolidated  balance  sheet  of the  Borrower  and its  Subsidiaries  as at the
Balance Sheet Date, or the related consolidated  statements of income,  retained
earnings or cash flow for the fiscal year then ended,  other than changes in the
ordinary course of business that have not had any






                                     - 22 -


materially  adverse  effect  either  individually  or in  the  aggregate  on the
business or financial  condition of the Borrower and its Material  Subsidiaries,
taken as a whole.

         Section 4.6. Franchises, Patents, Copyrights, Etc. Each of the Borrower
and its  Subsidiaries,  respectively,  possesses or has a valid right to use all
material franchises,  patents,  copyrights,  inventions,  technology,  trademark
registrations,  trademarks,  trade names,  trade  secrets,  service  marks,  FCC
Licenses,  other  licenses and permits,  and rights in respect of the  foregoing
and, to the best of its knowledge,  patent and trademark applications and rights
in respect thereto (collectively,  the "Proprietary  Rights"),  adequate for the
conduct of its business  substantially  as now conducted  without known conflict
with any rights of others which could affect or impair in a material  manner the
business or assets of the  Borrower and its  Material  Subsidiaries,  taken as a
whole.  Except as disclosed in the financial  statements  referred to in Section
4.4,  the Borrower is not aware of any existing or  threatened  infringement  or
misappropriation  of (a) any Proprietary Rights of others by the Borrower or any
of its Subsidiaries or (b) any Proprietary  Rights of the Borrower or any of its
Subsidiaries by others,  in any way which might materially  adversely affect the
business,  assets or condition,  financial or otherwise, of the Borrower and its
Material Subsidiaries, taken as a whole.

         Section 4.7. No Litigation. There are no actions, suits, proceedings or
investigations of any kind pending or, to the Borrower's  knowledge,  threatened
against the Borrower or any of its  Subsidiaries  before any court,  tribunal or
administrative  agency or board that,  if adversely  determined  are  reasonably
likely to in the aggregate,  materially adversely affect the properties, assets,
financial  condition or business of the Borrower and its Material  Subsidiaries,
taken as a whole or materially impair the right of the Borrower and its Material
Subsidiaries,  taken as a  whole,  to carry  on  business  substantially  as now
conducted by them, or result in any substantial liability not adequately covered
by  insurance,  or  for  which  adequate  reserves  are  not  maintained  on the
consolidated  balance sheet of the Borrower,  or which  question the validity of
this Credit Agreement or any of the other Loan Documents, or any action taken or
to be taken pursuant hereto or thereto. There are no final judgments against the
Borrower  or  any  of  its  Subsidiaries  that,  with  other  outstanding  final
judgments,  undischarged and not covered by insurance,  exceeds in the aggregate
five percent (5%) of the Consolidated Net Worth of the Borrower.

         Section 4.8. No Materially Adverse Contracts, Etc. Neither the Borrower
nor any of its Subsidiaries is subject to any charter,  corporate or other legal
restriction,  or any judgment, decree, order, rule or regulation that has or, to
the Borrower's knowledge, is expected in the future to have a materially adverse
effect on the  business,  assets or financial  condition of the Borrower and its
Material  Subsidiaries,  taken as a whole.  Neither the  Borrower nor any of its
Subsidiaries is a party to any contract or agreement that has or, to the best of
the  Borrower's  knowledge,  is  expected,  in the  judgment  of the  Borrower's
officers,  to have any materially adverse effect on the business of the Borrower
and its Material Subsidiaries, taken as a whole.

         Section 4.9. Compliance With Other Instruments,  Laws, Etc. Neither the
Borrower nor any of its  Subsidiaries  is in  violation of any  provision of its
charter documents, bylaws, or any agreement or instrument to which it is subject
or by  which  it or  any of its  properties  are  bound  or any  decree,  order,
judgment, statute, license, rule or regulation, in any of the foregoing cases in
a manner that are  reasonably  likely to result in the imposition of substantial
penalties or materially and adversely affect the financial






                                     - 23 -


condition, properties or business of the Borrower and its Material Subsidiaries,
taken as a whole or the Borrower's ability to perform the Obligations.

         Section  4.10.  Tax  Status.  The  Borrower  and,  to the  best  of the
Borrower's  knowledge,  its Subsidiaries  have (a) made or filed all federal and
state  income and all other  material  tax  returns,  reports  and  declarations
required by any  jurisdiction  to which any of them is subject or properly filed
for and received  extensions  with respect thereto which are still in full force
and effect and which have been fully complied with in all material respects, (b)
paid  all  taxes  and  other  governmental  assessments  and  charges  shown  or
determined to be due on such  returns,  reports and  declarations,  except those
being contested in good faith by appropriate  proceedings and for which adequate
reserves,  to the extent required by Generally Accepted  Accounting  Principles,
have been  established  and (c) set aside on their books  provisions  reasonably
adequate for the payment of all  estimated  taxes for periods  subsequent to the
periods  to which such  returns,  reports or  declarations  apply.  There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and the officers of the Borrower know of no basis for any such
claim.

         Section 4.11.  No Event of Default.  No Default or Event of Default has
occurred and is continuing.

         Section 4.12.  Holding Company and Investment Company Acts. Neither the
Borrower nor any of its  Subsidiaries is a "holding  company",  or a "subsidiary
company" of a "holding  company",  or an affiliate" of a "holding  company",  as
such terms are defined in the Public Utility Holding Company Act of 1935; nor is
it a "registered investment company", or an "affiliated company" or a "principal
underwriter" of a "registered  investment company", as such terms are defined in
the Investment Company Act of 1940.

         Section   4.13.   Certain   Transactions.   Except  for  arm's   length
transactions  pursuant to which the  Borrower  makes  payments  in the  ordinary
course of business upon terms no less  favorable  than the Borrower could obtain
from third parties and transactions  disclosed in the Borrower's Form 10-K filed
with the Securities and Exchange  Commission for its fiscal year ending December
31, 1996, none of the officers, directors or other key employees of the Borrower
or any of its Material Subsidiaries is presently a party to any transaction with
the  Borrower or any of its  Material  Subsidiaries  (other than for services as
employees,  officers and directors),  including any contract, agreement or other
arrangement  providing for the  furnishing  of services to or by,  providing for
rental of real or personal property to or from, or otherwise  requiring payments
to or from any officer,  director or such key  employee or, to the  knowledge of
the Borrower, any corporation,  partnership,  trust or other entity in which any
officer,  director, or any such key employee has a substantial interest or is an
officer, director, trustee or partner.

         Section 4.14.  ERISA Compliance.

         (a) In General. To the best of the Borrower's  knowledge,  the Borrower
and its Subsidiaries  have complied in all material  respects with provisions of
the Code,  to the extent  applicable,  and of ERISA  relevant to the  Borrower's
Pension Plans (as defined in Section 3(2) of ERISA),  including  the  provisions
thereof respecting funding  requirements for, and the termination of, such plans
and respecting prohibited






                                     - 24 -


transactions thereunder, and the funding of any Guaranteed Pension Plan complies
with the minimum funding standards of Section 412 of the Code.

         (b) Guaranteed Pension Plans. Each contribution  required to be made to
a Guaranteed  Pension Plan,  whether required to be made to avoid the incurrence
of an accumulated funding  deficiency,  the notice or lien provisions of Section
302(f) of ERISA, or otherwise, has been timely made. No waiver of an accumulated
funding  deficiency or extension of amortization  periods has been received with
respect to any  Guaranteed  Pension  Plan.  No liability to the PBGC (other than
required insurance  premiums,  all of which have been paid) has been incurred by
the Borrowers or any ERISA Affiliate with respect to any Guaranteed Pension Plan
and  there  has not been any  ERISA  Reportable  Event,  or any  other  event or
condition  which  presents  a material  risk of  termination  of any  Guaranteed
Pension  Plan by the PBGC.  Based on the  latest  valuation  of each  Guaranteed
Pension Plan (which in each case  occurred  within  twelve months of the date of
this representation),  and except as disclosed on Schedule 4.14 attached hereto,
the current value of all accrued  benefits  under each of such plans did not, as
of the latest  valuation  date,  exceed the then current  value of the assets of
such plans allocable to such accrued  benefits based upon the actuarial  methods
and assumptions used for such plans.

         (c) Multiemployer  Plans.  Neither the Borrower nor any ERISA Affiliate
has incurred any  material  liability  (including  secondary  liability)  to any
Multiemployer  Plan as a result of a complete  or partial  withdrawal  from such
Multiemployer  Plan  under  Section  4201 of ERISA  or as a result  of a sale of
assets  described in Section  4204 of ERISA.  Neither the Borrower nor any ERISA
Affiliate has been notified that any Multiemployer  Plan is in reorganization or
insolvent  under and within the meaning of Section 4241 or Section 4245 of ERISA
or that any Multiemployer Plan intends to terminate or has been terminated under
Section 4041A of ERISA.

         Section 4.15.  Purpose Credit.

         (a) The Borrower has 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 respective  meanings of each of the
quoted terms under Regulation U of the Board of Governors of the Federal Reserve
System.

         (b) The Borrower shall not,  directly or indirectly,  apply any part of
the  proceeds  of the  Notes  for  the  purpose  of or in  connection  with  the
Borrower's broker-dealer  activities, if any, within the meaning of Regulation T
of the Federal  Reserve Board (Title 12, Part 220, Code of Federal  Regulations,
as amended) or any published regulations, interpretations or rulings thereunder.

         (c) The  issuance  of the Notes  and the  application  of the  proceeds
thereof by the Borrower will not contravene  Regulation X of the Federal Reserve
Board  (Title 12,  Part 224,  Code of Federal  Regulations,  as  amended) or any
published regulations, interpretations or rulings thereunder.

         (d) The Borrower shall not,  directly or indirectly,  apply any part of
the  proceeds  of the Notes for the  purpose  of (i)  knowingly  purchasing,  or
providing  credit  support for the purchase  of,  Ineligible  Securities  from a
Section 20  Subsidiary  during any  period in which such  Section 20  Subsidiary
makes a market in such  Ineligible  Securities,  (ii) knowingly  purchasing,  or
providing credit support for the






                                     - 25 -


purchase  of,  during the  underwriting  or  placement  period,  any  Ineligible
Securities being underwritten or privately placed by a Section 20 Subsidiary, or
(iii)  making,  or  providing  credit  support  for the making of,  payments  of
principal or interest on Ineligible Securities  underwritten or privately placed
by a Section 20  Subsidiary  and issued by or for the benefit of the Borrower or
any Subsidiary or other Affiliate of the Borrower.

         Section 4.16.  Environmental Compliance.

                               (a) The Borrower has no actual knowledge that any
                  operator of the Real Estate,  has  violated,  or is alleged to
                  have violated, any judgment, decree, order, law, license, rule
                  or regulation pertaining to environmental matters (hereinafter
                  "Environmental  Laws"),  which violation would have a material
                  adverse effect on the  environment or the business,  assets or
                  financial  condition  of the  Borrower or any of its  Material
                  Subsidiaries, taken as a whole.


                               (b) Neither the  Borrower nor any of its Material
                  Subsidiaries   has  received   notice  from  any  third  party
                  including,  without  limitation,  any federal,  state or local
                  governmental  authority,  (i)  that  any one of them  has been
                  identified  by  the  United  States  Environmental  Protection
                  Agency  ("EPA") as a potentially  responsible  party under the
                  Comprehensive   Environmental   Response,   Compensation   and
                  Liability  Act of 1980 with  respect  to a site  listed on the
                  National  Priorities List, 40 C.F.R. Part 300 Appendix B; (ii)

                  Section  9601(14),  any pollutant or contaminant as defined by
                  42 U.S.C.  Section 9601(33) and any toxic  substances,  oil or

                  by any Environmental Laws (hereinafter "Hazardous Substances")
                  which any one of them has  generated,  transported or disposed
                  of has been  found at any  site at which a  federal,  state or
                  local agency or other third party has conducted or has ordered
                  that the Borrower or any of its Material  Subsidiaries conduct
                  a remedial  investigation,  removal or other  response  action
                  pursuant  to any  Environmental  Law;  or (iii)  that it is or
                  shall be a named party to any claim,  action, cause of action,
                  complaint,  or legal  or  administrative  proceeding  (in each
                  case,  contingent  or  otherwise)  arising  out of  any  third
                  party's  incurrence of costs,  expenses,  losses or damages of
                  any  kind   whatsoever  in  connection  with  the  release  of
                  Hazardous Substances.


                               (c)  Neither the Borrower nor any of its
                  Material Subsidiaries are subject to any applicable 
                  environmental law requiring the performance of Hazardous 
                  Substances site

                  Substances, or the giving of notice to any governmental agency

                  the  effectiveness  of  any  other  transactions  contemplated
                  hereby.


         Section 4.17.  Compliance With Fair Labor Standards Act. To the best of
the Borrower's knowledge, the Borrower has at all times operated its business in
compliance  with all  applicable  provisions of the Fair Labor  Standards Act of
1938 (29 U.S.C.  Section 106 and 207)  except to the extent that the  Borrower's
failure  to comply  therewith  would not have a material  adverse  affect on the
business,  assets or condition,  financial or otherwise, of the Borrower and its
Material  Subsidiaries,  taken  as a  whole.  To  the  best  of  the  Borrower's
knowledge,  none of the Borrower's  inventory has been produced by employees who
are or were employed in violation of the minimum wage or maximum hour provisions
of such Act or any regulations thereunder.

         Section  4.18.  Subsidiaries.  Attached  hereto as  Schedule  4.18 is a
schedule  showing with respect to each Material  Subsidiary the  jurisdiction in
which it is organized and the approximate  percentage of the outstanding  Voting
Stock of that Subsidiary held either by the Borrower or another Subsidiary.  All
of the  outstanding  capital  stock of each  Material  Subsidiary  has been duly
authorized  and issued and is  fully-paid  and  non-assessable;  and,  except as
indicated in Schedule 4.18, free and clear of any pledge, charge, lien, security
interest or other encumbrance or restriction on transfer.

         Section 4.19.  Disclosure.  No  representation  or warranty made by the
Borrower in any of the Loan  Documents or in any other  document  furnished from
time to time in connection herewith or therewith, contains any misrepresentation
of a material  fact or omits to state any  material  fact  necessary to make the
statements  herein or  therein  not  misleading.  There is no fact  known to the
Borrower that materially adversely affects, or that might reasonably be expected
to materially adversely affect, the business, property or financial condition of
the Borrower and its Material Subsidiaries on a consolidated basis.

         Section 5.        AFFIRMATIVE COVENANTS OF THE BORROWER.  The Borrower
covenants  and agrees that,  so long as any Loan or Note is  outstanding  or any
Bank has any obligation to make any Loans hereunder:

         Section 5.1.  Punctual  Payment.  The Borrower will duly and punctually
pay or cause to be paid the principal and interest on the Loans and the Facility
Fee, all in accordance with the terms of this Credit Agreement and the Notes.

         Section 5.2.  Maintenance  of Office.  The Borrower  will  maintain its
chief  executive  office in  Chicago,  Illinois,  or at such other  place in the
United States of America as the Borrower shall  designate upon written notice to
the Administrative  Agent,  where notices,  presentations and demands to or upon
the Borrower in respect of the Loan Documents may be given or made.






                                     - 27 -


         Section 5.3.  Records and  Accounts.  The Borrower  will (a) keep,  and
cause each of its  Subsidiaries to keep, true and accurate  records and books of
account in which full,  true and correct entries will be made in accordance with
Generally Accepted Accounting  Principles and (b) maintain adequate accounts and
reserves  for all  taxes  (including  income  taxes),  depreciation,  depletion,
obsolescence  and  amortization  of its  properties  and the  properties  of its
Subsidiaries, contingencies, and other reserves.

         Section 5.4. Financial  Statements,  Certificates and Information.  The
Borrower will deliver to each of the Banks or, with respect to subsection (f) of
this Section 5.4 only,  make  available  to each of the Banks at the  Borrower's
principal place of business:

         (a) as soon as practicable, but in any event not later than ninety (90)
days after the end of each fiscal year of the Borrower, the consolidated balance
sheet of the Borrower and its  Subsidiaries  as at the end of such year, and the
related consolidated  statements of income, retained earnings and cash flows for
such year,  each setting forth in comparative  form the figures for the previous
fiscal year and all such  consolidated  statements to be in  reasonable  detail,
prepared in  accordance  with  Generally  Accepted  Accounting  Principles,  and
certified  without material  qualification  as to any  circumstance  which could
reasonably be expected to have a material adverse effect on the Borrower and its
Material  Subsidiaries,  taken as a whole, by independent  public accountants of
nationally  recognized  standing  selected by the Borrower and acceptable to the
Majority Banks,  together with a written  statement from such accountants to the
effect that they have read a copy of this Credit Agreement,  and that, in making
the examination necessary to said certification, they have obtained no knowledge
of any Default or Event of Default,  or, if such accountants shall have obtained
knowledge of any then existing  Default or Event of Default they shall  disclose
in such  statement  any such  Default or Event of  Default;  provided  that such
accountants  shall not be liable to the Banks for failure to obtain knowledge of
any Default or Event of Default;

         (b) as soon as practicable,  but in any event not later than forty-five
(45) days after the end of each of the first  three  fiscal  quarters in each of
the Borrower's fiscal years, copies of the unaudited  consolidated balance sheet
of the  Borrower and its  Subsidiaries  as at the end of such  quarter,  and the
related  consolidated  statements  of income and cash flows for such quarter and
the  portion  of  the  Borrower's  fiscal  year  then  elapsed,   together  with
comparative consolidated figures for the same periods of the preceding year, all
in  reasonable  detail  and  prepared  in  accordance  with  Generally  Accepted
Accounting  Principles  and  accompanied  by  a  certificate  of  the  principal
financial officer of the Borrower stating that the information contained in such
financial  statements is correct and complete and fairly  presents the financial
position  of the  Borrower  and its  Subsidiaries  on the date  thereof  and the
results of their operations for the periods covered thereby (subject to year-end
adjustments);

         (c)  simultaneously  with  the  delivery  of the  financial  statements
referred  to in  subsections  (a) and (b) above,  a statement  certified  by the
principal financial officer of the Borrower in substantially the form of Exhibit
C  hereto  and  setting  forth  in  reasonable  detail  computations  evidencing
compliance with the covenants contained in Sections 7.1 and 7.2 as at the end of
the period covered by such  statements or during such period as may be required,
and (if applicable)






                                     - 28 -


reconciliations to reflect changes in Generally Accepted  Accounting  Principles
since the Balance Sheet Date (each, a "Compliance Certificate");

         (d) contemporaneously with the filing or mailing thereof, copies of all
material of a financial nature filed with the Securities and Exchange Commission
or sent to the  stockholders  of the  Borrower  or any holder of the  Borrower's
Funded Debt;

         (e) promptly upon request by the Administrative  Agent or any Bank, all
detailed  audits or reports  submitted  to the  Borrower by  independent  public
accountants in connection  with any annual or interim audits of the books of the
Borrower or any Material Subsidiary; and

         (f) from time to time upon request by the  Administrative  Agent or any
Bank, such other financial data and information (including,  without limitation,
accountants management letters and such other information regarding the business
and  affairs  and  condition,   financial  and  other,  of  the  Borrower,   its
Subsidiaries and their respective properties) as the Administrative Agent or any
Bank may reasonably request, subject to the confidentiality provisions set forth
in Section 25 hereof.

         Section  5.5.  Corporate  Existence;  Maintenance  of  Properties.  The
Borrower  will do or cause to be done all things  necessary to preserve and keep
in full force and effect its corporate  existence,  material rights,  franchises
and Proprietary  Rights and those of its Subsidiaries  except to the extent that
the Borrower's failure to do so will not have a materially adverse effect on the
assets,  financial  condition  or  business  of the  Borrower  and its  Material
Subsidiaries, taken as a whole. It (a) will cause all of its material properties
and those of its  Subsidiaries  used or useful in the conduct of its business or
the business of its  Subsidiaries  to be maintained and kept in good  condition,
repair and working order and supplied with all reasonably  necessary  equipment,
(b)  will  cause  to  be  made  all  reasonably  necessary  repairs,   renewals,
replacements,  betterments and improvements  thereof,  all as in the judgment of
the Borrower may be  necessary  so that the  business  carried on in  connection
therewith  may be properly and  advantageously  conducted at all times,  and (c)
will, and will cause each of its Material  Subsidiaries  to,  continue to engage
primarily in the  businesses  now  conducted by them and in related  businesses;
provided  that  nothing in this  Section  5.5 shall  prevent the  Borrower  from
discontinuing the operation and maintenance of any of its properties or those of
its Material Subsidiaries if such discontinuance is, in the sole judgment of the
Borrower,  desirable in the conduct of its or their  business and that do not in
the aggregate  materially  adversely affect the business of the Borrower and its
Material Subsidiaries on a consolidated basis.

         Section 5.6.  Insurance.  The Borrower will, and will cause each of its
Subsidiaries  to,  maintain  with  financially  sound  and  reputable   insurers
insurance  with respect to its insurable  properties  and business  against such
casualties  and  contingencies  as  shall  be in  accordance  with  the  general
practices of  businesses  engaged in similar  activities  in similar  geographic
areas and in amounts,  containing such terms, in such forms and for such periods
as  may  be  reasonably  satisfactory  to the  Administrative  Agent;  provided,
however,  that the  Borrower and any  Subsidiary  may  self-insure  for physical
damage to automobiles,  welfare benefits and against liability to workers in any
state or jurisdiction,  or may effect worker's  compensation  insurance  therein
through an insurance fund operated by such state or jurisdiction;  and provided,
further,  that  notwithstanding  anything to the contrary  contained herein, the
Borrower  or such  Subsidiary  will keep its  assets  which are of an  insurable
character insured by






                                     - 29 -


financially  sound  and  reputable  insurers  against  loss or damage by fire or
explosion in amounts  sufficient to prevent the Borrower or such Subsidiary from
becoming a co-insurer  and not in any event less than 80% of the full  insurable
value of the property insured.

         Section 5.7. Taxes;  Etc. The Borrower will, and will cause each of its
Subsidiaries to, (a) duly pay and discharge, or cause to be paid and discharged,
before  the same  shall  become  overdue or (b)  properly  file for and  receive
extensions for such payment and duly pay and discharge,  or cause to be paid and
discharged,  within such  extension  period,  all taxes,  assessments  and other
governmental  charges  (other than  taxes,  assessments  and other  governmental
charges imposed by foreign jurisdictions,  including states in which neither the
Borrower  nor  any  of its  Subsidiaries  conducts  a  material  portion  of its
business,  that in the  aggregate  are not material to the business or assets of
the Borrower on an individual basis or of the Borrower and its Subsidiaries on a
consolidated  basis)  imposed  upon  it  and  its  real  properties,  sales  and
activities,  or any part thereof,  or upon the income or profits  therefrom,  as
well as all claims for labor, materials, or supplies that if unpaid might by law
become a lien or charge upon any of its  property;  provided  that any such tax,
assessment,  charge,  levy or claim need not be paid if the  validity  or amount
thereof shall  currently be contested in good faith by  appropriate  proceedings
and if the  Borrower  or such  Subsidiary  shall  have set  aside  on its  books
adequate  reserves with respect thereto;  and provided further that the Borrower
and each  Subsidiary  of the  Borrower  will pay all  such  taxes,  assessments,
charges,  levies or claims  forthwith  upon the  commencement  of proceedings to
foreclose any lien that may have attached as security therefor.

         Section 5.8.  Inspection of Properties  and Books.  The Borrower  shall
permit the Banks,  through the  Administrative  Agent or any of the Banks' other
designated  representatives,  to visit and inspect any of the  properties of the
Borrower  or any of its  Subsidiaries,  to  examine  the books of account of the
Borrower  and  its  Subsidiaries  (and  to  make  copies  thereof  and  extracts
therefrom),  and to discuss the  affairs,  finances and accounts of the Borrower
and its  Subsidiaries  with,  and to be advised as to the same by, its and their
officers,  employees and independent  public accountants (such accountants being
hereby  authorized  by the  Borrower  to so  discuss  and  advise)  all at  such
reasonable  times  and  intervals  as the  Administrative  Agent or any Bank may
reasonably request. In connection with any such inspections or discussions, each
Bank,  on behalf of itself and any  representative  authorized  by it, agrees to
treat all non-public information as confidential information pursuant to Section
25  and  to  take  all  reasonable  precautions  to  prevent  such  confidential
information  from being  exposed to third  parties and to those of its employees
and  representatives  who do not  need to know  such  confidential  information;
provided  that this Section 5.8 shall not affect the  disclosure  by any Bank of
information  required to be disclosed to its  auditors,  regulatory  agencies or
pursuant  to  subpoena  or other  legal  process  or by virtue of any other law,
regulation, order or interpretation.

         Section 5.9. Compliance with Laws,  Contracts,  Licenses,  and Permits.
The Borrower will, and will cause each of its Material  Subsidiaries  to, comply
with (a) the applicable laws and regulations wherever its business is conducted,
including all  Environmental  Laws which may be in effect from time to time, (b)
the  provisions of its charter  documents and by-laws,  (c) all  agreements  and
instruments  by which it or any of its  properties  or business may be bound and
(d) all applicable decrees,  orders, and judgments; if in each such case failure
to  comply  would  have a  materially  adverse  effect on the  Borrower  and its
Material  Subsidiaries,  taken  as a whole.  If at any  time any  authorization,
consent, approval, permit or license from any officer, agency or instrumentality
of any






                                     - 30 -


government  shall  become  necessary  or required in order that the Borrower may
fulfill any of the  Obligations,  the Borrower will promptly take or cause to be
taken all  reasonable  steps  within the power of the  Borrower  to obtain  such
authorization,  consent,  approval, permit or license and furnish the Banks with
evidence thereof.

         Section 5.10.  Pension Plans.  The Borrower and any ERISA Affiliate 
shall:

         (a)  promptly  after the Borrower or any ERISA  Affiliate  knows or has
reason  to know  that any  ERISA  Reportable  Event  has  occurred,  notify  the
Administrative Agent that such ERISA Reportable Event has occurred;

         (b) promptly upon request make available to each Bank at the Borrower's
principal place of business a copy of (i) any actuarial statement related to any
pension plan required to be submitted  under Section 103(d) of ERISA or (ii) any
notice,  report or demand sent or received by a pension plan under  Section 4065
of ERISA;

         (c)  furnish  to each  Bank  forthwith,  a copy of (i) any  notice of a
pension plan  termination  sent to the PBGC under  Section  4041(a) of ERISA and
(ii) any  notice,  report or demand  sent or  received  by a pension  plan under
Sections 4041, 4042, 4043, 4063, 4066 or 4068 of ERISA; and

         (d)  furnish to each Bank a copy of any  request  for  waiver  from the
funding  standards or extension of the amortization  periods required by Section
412 of the Code no later than the date on which the request is  submitted to the
Department of Labor or the Internal Revenue Service, as the case may be.

         Section 5.11. Further Assurances.  The Borrower will cooperate with the
Banks and the  Administrative  Agent and execute  such further  instruments  and
documents as the Banks or the  Administrative  Agent shall reasonably request to
carry out to their  satisfaction  the  transactions  contemplated by this Credit
Agreement and the other Loan Documents.

         Section  5.12.   Notices.   The  Borrower  will  promptly   notify  the
Administrative  Agent and each of the Banks in writing of the  occurrence of any
Default or Event of  Default.  If any  Person  shall give any notice or take any
other action in respect of a claimed  default  (whether or not  constituting  an
Event of Default)  under this Credit  Agreement  or any other note,  evidence of
indebtedness,  indenture or other  obligation  to which or with respect to which
the  Borrower  or any of its  Subsidiaries  is a party or  obligor,  whether  as
principal or surety, the Borrower shall forthwith give written notice thereof to
each of the Banks, describing the notice or action and the nature of the claimed
default.

         Section 5.13.  Fair Labor  Standards  Act. The Borrower  will, and will
cause  each of its  Subsidiaries  to,  at all  times  operate  its  business  in
compliance  with all  applicable  provisions of the Fair Labor  Standards Act of
1938 (29  U.S.C.  Sections  206 and 207) if the  failure  to  comply  with  such
provisions might  reasonably be expected to have a materially  adverse affect on
the Borrower and its Subsidiaries, taken as a whole.







                                     - 31 -


         Section  5.14.  Environmental  Events.  The Borrower will promptly give
notice to the Administrative Agent (a) of any violation of any Environmental Law
that the Borrower or any of its Subsidiaries reports in writing or is reportable
by such Person in writing (or for which any written report  supplemental  to any
oral report is made) to any federal, state or local environmental agency and (b)
upon becoming aware thereof, of any inquiry, proceeding, investigation, or other
action, including a notice from any agency of potential environmental liability,
or any  federal,  state or local  environmental  agency  or  board,  that  might
reasonably be expected to materially  adversely affect the assets,  liabilities,
financial conditions or operations of the Borrower and its Material Subsidiaries
on a consolidated basis.

         Section 5.15.  Notification of Claims.  The Borrower will,  immediately
upon becoming aware thereof,  notify the Administrative  Agent in writing of any
uninsured  set-off,  claims  (including,   with  respect  to  the  Real  Estate,
environmental claims),  withholdings or other defenses which might reasonably be
expected  to  have a  materially  adverse  affect  on the  assets,  liabilities,
financial conditions or operations of the Borrower and its Material Subsidiaries
on a consolidated basis.

         Section  5.16.  Use of Proceeds.  The Borrower will use the proceeds of
the Loans for general  corporate  purposes,  including  without  limitation  the
financing  of  acquisitions,   capital  expenditures  and  for  working  capital
purposes.

         Section 5.17. Notice of Litigation,  Judgment and Material Events.  The
Borrower will give notice to the Administrative  Agent in writing within fifteen
(15) days of becoming  aware of any  litigation  or  proceedings  threatened  in
writing or any pending litigation and proceedings  affecting the Borrower or any
of its  Subsidiaries  or to which the Borrower or any of its  Subsidiaries is or
becomes a party involving an uninsured  claim against the Borrower  individually
or the  Borrower  and  its  Subsidiaries  on a  consolidated  basis  that  could
reasonably be expected to have a materially  adverse  effect on the Borrower and
its  Subsidiaries  on a consolidated  basis and stating the nature and status of
such  litigation or  proceedings.  The Borrower will, and will cause each of its
Subsidiaries to, give notice to the  Administrative  Agent, in writing,  in form
and detail satisfactory to the Administrative Agent, (a) within ten (10) days of
any judgment not covered by insurance or reserves,  final or otherwise,  against
the Borrower or any of its  Subsidiaries  in an amount  which in aggregate  with
other such  judgments  against the Borrower or any of its  Subsidiaries  exceeds
five percent (5%) of the Consolidated Net Worth of the Borrower and (b) promptly
after  becoming  aware  thereof,  of the  occurrence  of any  event  that  it is
reasonable  to expect  will be  required  to be  reported  to or filed  with the
Securities and Exchange Commission.

         Section 6.        CERTAIN NEGATIVE COVENANTS OF THE BORROWER.  The
Borrower  covenants and agrees that, so long as any Loan or Note is  outstanding
or any Bank has any obligation to make any Loans hereunder:

         Section 6.1.  Indebtedness.  The Borrower will not, and will not permit
any of its  Subsidiaries  to,  incur any Funded Debt if an Event of Default will
occur hereunder  immediately after giving effect thereto as a consequence of the
incurrence of such Funded Debt.  The Borrower  will not incur any  obligation to
repay money borrowed in an aggregate  amount in excess of $150,000,000  under or
in






                                     - 32 -


connection with any line of credit having an initial or scheduled  maturity date
of less than one year from the initial borrowing date or renewal date therefor.

         Section 6.2  Restrictions on Liens.

         Section 6.2.1.  The Borrower.  The Borrower will not create or incur or
suffer to be  created or  incurred  or to exist any Lien of any kind upon any of
its  property  or  assets  of any  character,  whether  now  owned or  hereafter
acquired,  or upon the income or profits therefrom to secure Funded Debt without
in any  such  case  effectively  providing  concurrently  with the  creation  or
incurrence of any such Liens that the  Obligations  shall be secured equally and
ratably  with (or, at the option of the  Borrower,  prior to) such Funded  Debt,
unless  immediately  after the  incurrence of such Funded Debt (and after giving
effect to the  application of the proceeds,  if any,  therefrom),  the aggregate
principal amount of all such Funded Debt,  together with the aggregate amount of
Capitalized Rent in respect of Sale and Leaseback  Transactions (other than Sale
and Leaseback Transactions  described in clauses (a) through (d), inclusive,  of
Section6.8),  would not exceed two percent (2%) of Consolidated  Capitalization;
provided that the foregoing  restrictions shall not apply to, and there shall be
excluded in computing the  aggregate  amount of Funded Debt secured by Liens for
the purpose of such restrictions:

         (a) liens to secure taxes,  assessments and other government charges in
respect of  obligations  not overdue or liens on properties to secure claims for
labor,  material or supplies in respect of obligations not overdue or in respect
of which the Borrower  shall at the time in good faith be  prosecuting an appeal
or proceeding for review and in respect of which a stay of execution  shall have
been obtained pending such appeal or review and for which any reserves  required
in  accordance  with  Generally   Accepted   Accounting   Principles  have  been
established;

         (b) deposits or pledges made in connection  with, or to secure  payment
of, workmen's compensation,  unemployment  insurance,  old age pensions or other

at the time in good faith be  prosecuting an appeal or proceeding for review and
in respect of which a stay of execution  shall have been  obtained  pending such
appeal  or review  and for  which  any  reserves  required  in  accordance  with
Generally Accepted Accounting Principles have been established;

         (d) liens of carriers,  warehousemen,  mechanics and  materialmen,  and
other like liens on properties in existence  less than 120 days from the date of
creation thereof in respect of obligations not overdue;

         (e)  encumbrances  consisting  of  easements,  rights  of  way,  zoning
restrictions,  restrictions  on  the  use  of  real  property  and  defects  and
irregularities  in the title thereto,  landlord's or lessor's liens under leases
to which the Borrower is a party, and other minor liens or encumbrances  none of
which in the opinion of the Borrower  interferes  materially with the use of the
property affected in the ordinary conduct of the business of the Borrower, which
defects do not individually or in the






                                     - 33 -


aggregate have a materially adverse effect on the business of the Borrower 
individually or of the Borrower and its Subsidiaries on a consolidated basis;

         (f)  presently outstanding liens listed on Schedule 6.2.1 hereto;

         (g) liens on property  existing at the time the Borrower  acquires such
property and not created in  anticipation  of such  acquisition,  purchase money

be  incurred  hereunder  and  incurred in  connection  with the  acquisition  or
construction  of such  property at the time of or within 270 days  following the
acquisition of such property,  which security  interests or mortgages cover only
the real or personal property so acquired,  and Liens on existing  properties or
assets to secure Funded Debt permitted  hereunder and incurred for  improvements
on such properties or assets;

         (h) liens on the  property  of a Person (i)  existing  at the time such
Person is merged into or consolidated  with the Borrower as permitted  hereby or
at the time of a sale, lease or other  disposition of the properties of a Person
as an entirety or  substantially  as an  entirety to the  Borrower as  permitted
hereby,  (ii)  resulting  from  such  merger,  consolidation,   sale,  lease  or
disposition  by  virtue  of any Lien on  property  granted  by the  Borrower  as
permitted hereby prior to such merger, consolidation, sale, lease or disposition
(and not in contemplation  thereof or in connection  therewith) which applies to
after-acquired  property of the Borrower,  or (iii)  resulting from such merger,
consolidation,  sale,  lease or  disposition  pursuant to a Lien or  contractual
provision  granted  or  entered  into  by such  Person  prior  to  such  merger,
consolidation,  sale,  lease  or  disposition  (and  not at the  request  of the
Borrower); provided that any such Lien referred to in clause (i) shall not apply
to any property of the Borrower other than the property  subject  thereto at the
time such Person or  properties  were  acquired and any such Lien referred to in
clause (ii) or (iii) shall not apply to any property of the Borrower  other than
the property so acquired;

         (i) Liens arising by reason of deposits with, or the giving of any form
of security to, any  governmental  agency or any body created or approved by law
or  governmental  regulation,  which  Lien is  required  by law or  governmental
regulation as a condition to the  transaction of any business or the exercise of
any privilege,  franchise,  license or permit and Liens in favor of a government
or governmental entity to secure partial progress, advance or other payments, or
other  obligations,  pursuant  to any  contract  or  statute  or to  secure  any
indebtedness  incurred for the purpose of financing all or any part of the costs
of  acquiring,  constructing  or improving  the  property  subject to such Liens
(including,  without  limitation,  Liens  incurred in connection  with pollution
control, industrial revenue, private activity bond or similar financing); and

         (j) any extension,  renewal or replacement  (or successive  extensions,
renewals  or  replacements)  in whole or in part of any Lien  referred to in the
foregoing  clauses (a)  through  (i),  inclusive;  provided,  however,  that the
principal  amount secured thereby shall not exceed the principal  amount secured
thereby at the time of such  extension,  renewal or  replacement,  and that such
extension,  renewal  or  replacement  shall be  limited  to all or a part of the
property  which secured the  obligation so extended,  renewed or replaced  (plus
improvements to such property).







                                     - 34 -


         Section 6.2.2. Subsidiaries. No Subsidiary of the Borrower shall create
or incur or suffer to be  created or  incurred  or to exist any Lien of any kind
(but in any event,  subject to the  exceptions set forth in the last sentence of
this Section 6.2.2) upon any of its property or assets of any character, whether

waived; or

disposing or dumping) of Hazardous  Substances  on, upon or into the Real Estate
or (e) otherwise  conduct any activity at any Real Estate or use any Real Estate

Transaction,  so long as within 270 days of the effective  date of such Sale and
Leaseback Transaction, the Borrower applies (or irrevocably commits to an escrow

         (h)  a  decree  or  order  is  entered  appointing  any  such  trustee,
custodian,  liquidator  or receiver or  adjudicating  the Borrower or any of its
Material Subsidiaries bankrupt or insolvent, or approving a petition in any such
case or other proceeding,  or a decree or order for relief is entered in respect
of the Borrower or any  Material  Subsidiary  of the Borrower in an  involuntary
case under federal bankruptcy laws as now or hereafter constituted; or

         (i)  there  shall  remain  in  force,  undischarged,   unsatisfied  and
unstayed, for more than thirty (30) days, whether or not consecutive,  any final
judgment  against  the  Borrower  or any of its  Subsidiaries  that,  with other
outstanding final judgments,  undischarged and not covered by insurance, against
such Person(s)  exceeds in the aggregate  five percent (5%) of the  Consolidated
Net Worth of the Borrower;

then,  and in any  such  event,  so  long as the  same  may be  continuing,  the
Administrative  Agent may, and upon the request of the Majority Banks shall,  by
notice in writing to the Borrower declare all amounts owing with respect to this
Credit Agreement and the Notes to be, and they shall thereupon forthwith become,
immediately due and payable without presentment, demand, protest or other notice
of any kind, all of which are hereby expressly waived by the Borrower;  provided
that in the event of any Event of Default  specified in Section 10(g) or Section
10(h), all such amounts shall become  immediately due and payable  automatically
and without any requirement of notice from the Administrative Agent or any Bank.

         If any one or more of the Events of Default  specified in Section 10(g)
or Section 10(h) shall occur,  any unused portion of the credit  hereunder shall
forthwith  terminate and each of the Banks shall be relieved of all  obligations
to make Loans  hereunder.  If any other Event of Default shall have occurred and
be continuing, the Administrative Agent, upon the request of the Majority Banks,
shall,  by notice to the Borrower,  terminate  the unused  portion of the credit
hereunder,  and upon such notice  being given such unused  portion of the credit
hereunder shall terminate immediately and each of the Banks shall be relieved of
all  further  obligations  to make  Loans.  If any such  notice  is given to the
Borrower, the Administrative Agent will forthwith furnish a copy thereof to each
of the Banks. No termination of the credit  hereunder shall relieve the Borrower
of any of the  Obligations  or any  of its  existing  obligations  to the  Banks
arising under other agreements or instruments.








                                     - 42 -


         Section 11.  THE AGENTS.

         Section 11.1.  Authorization.

         (a) Each of the Agents is  authorized  to take such action on behalf of
each of the Banks  and to  exercise  all such  powers  as are  hereunder  and in
related  documents  delegated  to such Agent,  together  with such powers as are
reasonably  incident thereto;  provided that no duties or  responsibilities  not
expressly assumed herein or therein shall be implied to have been assumed by any
of the Agents.

         (b) The  relationship  between each of the Agents and each of the Banks
is  that  of an  independent  contractor.  The use of the  term  "Agent"  is for
convenience  only  and is  used  to  describe,  as a  form  of  convention,  the
independent contractual  relationship between each of the Agents and each of the
Banks.  Nothing  contained in this Credit  Agreement or the other Loan Documents
shall be construed to create an agency,  trust or other  fiduciary  relationship
between any of the Agents,  on the one hand, and any of the Banks,  on the other
hand.

         (c) As an  independent  contractor  empowered  by the Banks to exercise
certain  rights and perform  certain duties and  responsibilities  hereunder and
under the other Loan  Documents,  the  Administrative  Agent is  nevertheless  a
"representative"  of the  Banks,  as that term is  defined  in  Article 1 of the
Uniform  Commercial  Code,  for purposes of actions for the benefit of the Banks
and the Agents with respect to all  collateral  security and guaranties (if any)
contemplated by the Loan Documents.  Such actions include the designation of the
Administrative  Agent  as  "secured  party",  "mortgagee"  or  the  like  on all
financing  statements and other documents and  instruments,  whether recorded or
otherwise,  relating to the attachment,  perfection,  priority or enforcement of
any  security  interests,  mortgages  or deeds of trust in  collateral  security
intended to secure the payment or performance of any of the Obligations, all for
the benefit of the Banks and the Agents.

         Section  11.2.  Employees  and  Agents.  The  Administrative  Agent may
exercise its powers and execute its duties by or through employees or agents and
shall be  entitled to take,  and to rely on,  advice of counsel  concerning  all
matters  pertaining to its rights and duties under this Credit Agreement and the
other Loan Documents.  The Administrative Agent may utilize the services of such
Persons  as the  Administrative  Agent in its  sole  discretion  may  reasonably
determine,  and upon the occurrence and during the  continuation of a Default or
an Event of Default,  all reasonable fees and expenses of any such Persons shall
be paid by the Borrower.

         Section  11.3.  No  Liability.  None of the  Agents  nor  any of  their
respective shareholders,  directors,  officers or employees nor any other Person
assisting  them in their  duties  nor any agent or  employee  thereof,  shall be
liable for any waiver, consent or approval given or any action taken, or omitted
to be taken,  in good  faith by it or them  hereunder  or under any of the other
Loan Documents,  or in connection  herewith or therewith,  or be responsible for
the consequences of any oversight or error of judgment  whatsoever,  except that
each of the Agents or such other  Person,  as the case may be, may be liable for
losses due to its own willful misconduct or gross negligence.

         Section 11.4.  No Representations.

         (a) The Agents shall not be  responsible  for the execution or validity
or enforceability of this Credit Agreement or the Notes or any instrument at any
time constituting, or intended to constitute, collateral security for the Notes,
or  for  the  value  of any  such  collateral  security  or  for  the  validity,
enforceability  or  collectability of any such amounts owing with respect to the
Notes,  or for any recitals or statements,  warranties or  representations  made
herein or in any of the other Loan Documents or in any certificate or instrument
hereafter  furnished  to it by or on  behalf  of the  Borrower,  or be  bound to
ascertain or inquire as to the  performance  or  observance of any of the terms,
conditions,  covenants or  agreements  herein or in any  instrument  at any time
constituting, or intended to constitute,  collateral security for the Notes. The
Agents shall not be bound to ascertain whether any notice, consent,






                                     - 43 -


waiver or request  delivered to any of them by the Borrower or any holder of any
of the Notes shall have been duly authorized or is true,  accurate and complete.
The Agents have not made nor do they now make any representations or warranties,
express or implied,  nor do they assume any liability to the Banks, with respect
to the credit  worthiness or financial  conditions of the Borrower or any of its
Subsidiaries.  Each Bank  acknowledges  that it has,  independently  and without
reliance upon the  Administrative  Agent, the Documentation  Agent, the Managing
Agents,  or the other Banks, and based upon such information and documents as it
has deemed appropriate,  made its own credit analysis and decision to enter into
this Credit Agreement.

     (b) For purposes of determining compliance with the conditions set forth
in Section 8, each Bank that has executed this Credit  Agreement shall be deemed
to have  consented  to,  approved or  accepted,  or to be satisfied  with,  each
document and matter either sent, or made available,  by the Administrative Agent
or by BancBoston  Securities,  Inc., or TD Securities (USA), Inc., as arrangers,
to such Bank for consent,  approval,  acceptance  or  satisfaction,  or required
thereunder to be consented to or approved by or acceptable  or  satisfactory  to
such  Bank,  unless an  officer  of the  Administrative  Agent  active  upon the
Borrower's  account shall have received  notice from such Bank not less than two
(2) Business  Days prior to the Closing Date  specifying  such Bank's  objection
thereto  and such  objection  shall  not have  been  withdrawn  by notice to the
Administrative Agent to such effect on or prior to the Closing Date.

         Section 11.5.  Payments.

     (a) A payment by the Borrower to the  Administrative  Agent  hereunder or 
any of the other Loan  Documents for the account of any Bank shall  constitute a
payment to such Bank. The  Administrative  Agent agrees promptly to distribute 
to each Bank such Bank's pro rata share of payments received by the 
Administrative  Agent for the account of the Banks,  except as otherwise  
expressly  provided herein or in any of the other Loan Documents.

         (b) If in the opinion of the  Administrative  Agent the distribution of
any amount  received by it in such  capacity  hereunder or under the Notes might
involve it in liability, it may refrain from making distribution until its right
to make  distribution  shall  have  been  adjudicated  by a court  of  competent
jurisdiction. If a court of competent jurisdiction shall adjudge that any amount
received  and  distributed  by the  Administrative  Agent is to be repaid,  each
Person to whom any such distribution  shall have been made shall either repay to
the Administrative Agent its proportionate share of the amount so adjudged to be
repaid or shall pay over the same in such manner and to such Persons as shall be
determined by such court.

     (c) Notwithstanding  anything to the contrary  contained in this Credit 
Agreement or any of the other Loan  Documents,  any Bank that fails to make  
available to the Administrative  Agent  its pro rata  share of any Loan as,  
when and to the full extent  required by the  provisions  of this Credit  
Agreement,  shall be deemed delinquent  (a  "Delinquent  Bank") and shall be 
deemed a Delinquent  Bank until such time as such delinquency is satisfied. A 
Delinquent Bank shall be deemed to have  assigned  any and all  payments  due to
it from the  Borrower,  whether on account of  outstanding  Loans,  interest,  
fees or otherwise,  to the remaining nondelinquent  Banks for application to, 
and reduction of, their  respective pro rata shares of all outstanding  Loans. 
The Delinquent Bank hereby authorizes the Administrative  Agent to distribute 
such payments to the nondelinquent  Banks in proportion  to their  respective  
pro rata shares of all  outstanding  Loans.  A Delinquent Bank shall be deemed 
to have satisfied in full a delinquency when and if, as a result of application 
of the assigned payments to all outstanding Loans of the  nondelinquent  Banks, 
the  Banks'  respective  pro rata  shares  of all outstanding  Loans have  
returned to those in effect  immediately  prior to such delinquency   and 
without  giving  effect  to  the   nonpayment   causing  such delinquency.

         Section 11.6.  Holders of Notes.  Each of the Agents may deem and treat
the payee of any Note as the  absolute  owner  thereof for all  purposes  hereof
until it shall have been  furnished  in writing  with a  different  name by such
payee or by a subsequent holder.







                                     - 44 -


         Section 11.7.  Indemnity.  The Banks jointly and severally agree hereby
to indemnify  and hold  harmless each of the Agents from and against any and all
claims,  actions and suits (whether groundless or otherwise),  losses,  damages,
costs,  expenses  (including  any  expenses  for which  such  Agent has not been
reimbursed  by the  Borrower  as  required  by Section 12 or  Section  13),  and
liabilities  of every  nature and  character  arising  out of or related to this
Credit  Agreement  or the Notes or the  transactions  contemplated  or evidenced
hereby or thereby, or such Agent's actions taken hereunder or thereunder, except
to the extent that any of the same shall be directly  caused by such Agent's own
willful misconduct or gross negligence.

         Section 11.8. Agents as Banks. In their individual capacities,  each of
BankBoston and TD shall have the same  obligations  and the same rights,  powers
and  privileges in respect to its  Commitments  and the Loans made by it, and as
the  holder  of any of  the  Notes,  as it  would  have  were  it not  also  the
Administrative  Agent, the Documentation  Agent or a Managing Agent, as the case
may be.

         Section 11.9.  Resignation.  Any Agent may resign at any time by giving
ninety (90) days' prior  written  notice  thereof to the Banks and the Borrower.
Upon any such  resignation,  the Majority  Banks shall have the right to appoint
another Bank or any other  financial  institution as a successor  Administrative
Agent, Documentation Agent or Managing Agent, as applicable. Unless a Default or
Event of Default shall have occurred and be continuing, such successor, if other
than a Bank,  shall be reasonably  acceptable  to the Borrower.  If no successor
Administrative  Agent,  Documentation Agent or Managing Agent shall have been so
appointed by the Majority Banks and shall have accepted such appointment  within
thirty (30) days after the  retiring  Agent's  giving of notice of  resignation,
then the retiring  Administrative  Agent,  Documentation Agent or Managing Agent
may,  on  behalf  of  the  Banks,  appoint  a  successor  Administrative  Agent,
Documentation  Agent or Managing Agent,  respectively,  as the case may be. Upon
the acceptance of any  appointment as an Agent  hereunder by a successor  Agent,
such successor Agent shall  thereupon  succeed to and become vested with all the
rights,  powers,  privileges and duties of the retiring Agent,  and the retiring
Agent shall be discharged from its duties and obligations  hereunder.  After any
retiring  Agent's  resignation,  the provisions of this Credit  Agreement  shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as an Agent.

         Section  11.10.  Documentation  Agent;  Managing  Agents.  Neither  the
Documentation  Agent nor any of the Managing Agents shall have any right, power,
obligation,  liability,  responsibility  or duty  under this  Agreement  in such
capacity, other than those applicable to all Banks as Banks.

         Section 12.  EXPENSES.  The Borrower  agrees to pay (a) the  reasonable
cost of  producing  and  reproducing  this  Credit  Agreement,  the  other  Loan
Documents and the other  agreements and instruments  mentioned  herein,  (b) any
taxes  (including any interest and penalties in respect  thereto) payable by the
Administrative   Agent  or  the  Banks   (other   than  taxes   based  upon  the
Administrative  Agent's  or any Bank's  net  income)  on or with  respect to the
transactions contemplated by this Credit Agreement (the Borrower hereby agreeing
to indemnify the Banks with respect thereto),  (c) the reasonable fees, expenses
and disbursements of Special Counsel or any local counsel to the  Administrative
Agent  incurred  in  connection   with  the   preparation,   administration   or
interpretation  of the Loan Documents and other  instruments  mentioned  herein,
each closing hereunder, and amendments,  modifications,  approvals,  consents or
waivers  hereto or  hereunder  regardless  of whether  any such  transaction  is
consummated,  (d) the fees,  expenses and  disbursements  of the  Administrative
Agent incurred by the  Administrative  Agent in connection with the preparation,
administration  or  interpretation  of the Loan Documents and other  instruments
mentioned  herein,   each  closing  hereunder  and  amendments,   modifications,
approvals,  consents or waivers  hereto or hereunder,  regardless of whether any
such transaction is consummated,  and (e) all reasonable  out-of-pocket expenses
(including  reasonable  attorneys'  (which  attorneys  may be,  but shall not be
required to be,






                                     - 45 -


employees of any Bank or Agent) fees and costs) incurred by any Bank or Agent in
connection  with (i) the  enforcement of any of the Loan  Documents  against the
Borrower or any of its  Subsidiaries  or the  administration  thereof  after the
occurrence of a Default or Event of Default,  (ii) any  so-called  "work-out" of
the Obligations and (iii) any litigation,  proceeding or dispute whether arising
hereunder or otherwise in connection with the transactions  contemplated  hereby
or under the other  Loan  Documents,  in any way  related  to any  Bank's or any
Agent's relationship with the Borrower or any of its Subsidiaries. The covenants
of this Section 12 shall survive  payment or  satisfaction of payment of amounts
owing under or with respect to the Loan Documents.

         Section 13. INDEMNIFICATION.  The Borrower agrees to indemnify and hold
harmless  the Agents and the Banks from and against any and all claims,  actions
and suits  whether  groundless  or  otherwise,  and from and against any and all
liabilities,  losses, damages and expenses of every nature and character arising
out  of  this  Credit  Agreement  or  any of the  other  Loan  Documents  or the
transactions evidenced hereby unless any such claims, actions or suits arise out
of the Agents' or the Banks'  intentional  misconduct  or gross  negligence.  In
litigation,  or the  preparation  therefor,  the Banks and the  Agents  shall be
entitled  to  select  their  own  counsel  and,  in  addition  to the  foregoing
indemnity,  the Borrower agrees to pay promptly the reasonable fees and expenses
of such  counsel.  If, and to the extent that the  obligations  of the  Borrower
under this Section 13 are  unenforceable  for any reason,  the  Borrower  hereby
agrees to make the maximum  contribution  to the payment in satisfaction of such
obligations  which is permissible  under  applicable  law. The covenants of this
Section 13 shall  survive  payment or  satisfaction  of payment of amounts owing
under or with respect to the Loan Documents.

         Section 14.  SURVIVAL OF  COVENANTS,  ETC. All  covenants,  agreements,
representations  and warranties made herein,  in any of the other Loan Documents
or in any  documents or other  papers  delivered by or on behalf of the Borrower
pursuant  hereto  shall be deemed to have been  relied upon by the Banks and the
Administrative Agent,  notwithstanding any investigation heretofore or hereafter
made by any of them, and shall survive the making by the Banks of the Loans,  as
herein contemplated,  and shall continue in full force and effect so long as any
Obligation remains outstanding or any Bank has any obligation to make any Loans.
All statements contained in any certificate or other paper delivered to any Bank
or the Administrative Agent at any time by or on behalf of the Borrower pursuant
hereto  or  in  connection  with  the  transactions  contemplated  hereby  shall
constitute representations and warranties by the Borrower hereunder.

         Section 15. ASSIGNMENT AND PARTICIPATION.

     Section 15.1. Conditions to Assignment by Banks. Except as provided herein,
each Bank may assign to one or more  Eligible  Assignees all or a portion of its
interests,  rights and obligations under this Credit Agreement (including all or
a portion of its  Commitment  Percentage  and Commitment and the same portion of
the Loans at the time owing to it) and the Notes held by it;  provided  that (a)
the Administrative  Agent and the Borrower (unless such assignment is (i) to any
Federal Reserve Bank or (ii) from any Bank which is as  Administrative  Agent to
an  affiliate of an Agent)  shall have given its prior  written  consent to such
assignment,  which  consent  will not be  unreasonably  withheld,  (b) each such
assignment  shall be of a  constant,  and not a varying,  percentage  of all the
assigning Bank's rights and obligations  under this Credit  Agreement,  (c) each
Bank shall have a Commitment that is at least  $5,000,000 and (d) the parties to
such  assignment  shall  execute and deliver to the  Administrative  Agent,  for

hereinafter defined), an Assignment and Acceptance, substantially in the form of
Exhibit E hereto  (an  "Assignment  and  Acceptance"),  together  with any Notes
subject  to such  assignment.  Upon such  execution,  delivery,  acceptance  and
recording,  from and after the effective date  specified in each  Assignment and
Acceptance,  which effective date shall be at least five (5) Business Days after
the execution thereof,  (i) the assignee thereunder shall be a party hereto and,
to the extent provided in such  Assignment and  Acceptance,  have the rights and
obligations of a Bank  hereunder,  (ii) the assigning Bank shall,  to the extent
provided in such assignment and upon payment to the Administrative  Agent of the
registration  fee referred to in Section 15.3, be released from its  obligations
under this Credit  Agreement  and (iii)  Schedule  1.1(a)  shall be deemed to be
automatically  amended  to  reflect  the  change in the  Banks  and each  Bank's
Commitment  and  Commitment   Percentage  resulting  from  such  Assignment  and
Acceptance.

     Section  15.2.  Certain   Representations   and  Warranties;   Limitations;

to the assignment  thereunder confirm to and agree with each other and the other
parties hereto as follows:  (a) other than the  representation and warranty that
it is the legal and beneficial owner of the interest being assigned thereby free
and clear of any adverse claim,  the assigning Bank makes no  representation  or
warranty,  express or implied, and assumes no responsibility with respect to any
statements,  warranties or  representations  made in or in connection  with this
Credit  Agreement  or  the  execution,   legality,   validity,   enforceability,

Documents or any other instrument or document  furnished  pursuant hereto or the
attachment, perfection or priority of any security interest or mortgage; (b) the
assigning Bank makes no representation or warranty and assumes no responsibility
with respect to the financial  condition of the Borrower and its Subsidiaries or
any other  Person  primarily  or  secondarily  liable in  respect  of any of the

any of the Obligations of any of their  obligations  under this Credit Agreement
or any of the other Loan Documents or any other instrument or document furnished
pursuant  hereto or thereto;  (c) such assignee  confirms that it has received a
copy of this Credit Agreement, together with copies of the most recent financial
statements  referred to in Section 4.4 and Section 5.4 and such other  documents

decision to enter into such Assignment and  Acceptance;  (d) such assignee will,
independently  and without reliance upon the assigning Bank, the  Administrative

taking or not taking  action  under this  Credit  Agreement;  (e) such  assignee
represents  and  warrants  that it is an Eligible  Assignee;  (f) such  assignee

such assignee  agrees that it will perform in accordance with their terms all of
the  obligations  that by the terms of this Credit  Agreement are required to be
performed by it as a Bank; and (h) such assignee represents and warrants that it
is legally authorized to enter into such Assignment and Acceptance.

     Section 15.3.  Register.  The Administrative Agent shall maintain a copy of
each  Assignment and  Acceptance  delivered to it and a register or similar list
(the "Register") for the recordation of the names and addresses of the Banks and

absence of manifest






                                     - 47 -


error, and the Borrower,  the Administrative  Agent and the Banks may treat each
Person  whose name is  recorded  in the  Register  as a Bank  hereunder  for all
purposes  of  this  Credit  Agreement.  The  Register  shall  be  available  for
inspection by the Borrower and the Banks at any reasonable time and from time to
time upon reasonable  prior notice.  Upon each such  recordation,  the assigning
Bank agrees to pay to the Administrative  Agent a registration fee in the sum of
$3,000.

such  assignment,  the  Administrative  Agent  shall (a) record the  information

Assignment and  Acceptance  and, if the assigning Bank has retained some portion
of its obligations  hereunder,  a new Note to the order of the assigning Bank in
an amount  equal to the amount  retained by it  hereunder.  Such new Notes shall

aggregate  principal  amount  equal to the  aggregate  principal  amount  of the
surrendered  Notes,  shall be dated the effective  date of such  Assignment  and
Acceptance  and shall  otherwise  be in  substantially  the form of the assigned
Notes.  Upon the request of any Bank, the Borrower shall within five (5) days of
the issuance of any new Notes  pursuant to this Section 15.4, at the  requesting
Bank's  expense,  deliver an opinion of counsel,  addressed to the Banks and the
Administrative Agents, relating to the due authorization, execution and delivery
of such new Notes and the legality, validity and binding effect thereof, in form
and substance satisfactory to the Banks.  The surrendered Notes shall be
cancelled and returned to the Borrower.

     Section 15.5.  Participations.  Each Bank may sell participations to one or
more  banks or other  entities  in all or a portion  of such  Bank's  rights and
obligations  under this Credit Agreement and the other Loan Documents;  provided
that  (a)  each  such  participation  shall be in an  amount  of not  less  than
$5,000,000,  (b) any such sale or participation  shall not affect the rights and
duties of the selling  Bank  hereunder  to the  Borrower and (c) the only rights
granted to the  participant  pursuant to such  participation  arrangements  with
respect to waivers,  amendments or  modifications of the Loan Documents shall be
the rights to approve waivers, amendments or modifications that would reduce the
principal of or the interest rate on any Loans,  extend the term or increase the
amount of the Commitment of such Bank as it relates to such participant,  reduce
the amount of any facility fees to which such  participant is entitled or extend
any regularly scheduled payment date for principal or interest.

     Section  15.6.  Disclosure.   The  Borrower  agrees  that  in  addition  to
disclosures  made in accordance with standard and customary  banking  practices,
any Bank may in  accordance  with the  terms of  Section  25.2  hereof  disclose
information obtained by such Bank pursuant to this Credit Agreement to assignees
or participants and potential assignees or participants hereunder; provided that
such assignees or  participants  or potential  assignees or  participants  shall
agree  (a) to treat in  confidence  such  information  unless  such  information
otherwise  becomes public  knowledge,  (b) not to disclose such information to a
third party,  except as required by law or legal process and (c) not to make use
of such information for purposes of transactions  unrelated to such contemplated
assignment or participation.

     Section 15.7. Assignee or Participant  Affiliated with the Borrower. If any
assignee Bank is an Affiliate of the Borrower, then any such assignee Bank shall
have no  right  to vote as a Bank  hereunder  or  under  any of the  other  Loan
Documents  for  purposes  of  granting  consents  or waivers or for  purposes of
agreeing to amendments or other  modifications  to any of the Loan  Documents or
for purposes of making requests to the Administrative  Agent pursuant to Section
10, and the  determination  of the Majority Banks shall for all purposes of this
Agreement and the other Loan  Documents be made without  regard to such assignee
Bank's interest in any of the Loans. If any Bank sells a participating  interest
in any of the Loans to a participant, and such participant is the Borrower or an
Affiliate of the Borrower,  then such  transferor Bank shall promptly notify the
Administrative Agent of the sale of such participation.  A transferor Bank shall
have no  right  to vote as a Bank  hereunder  or  under  any of the  other  Loan
Documents  for  purposes  of  granting  consents  or waivers or for  purposes of
agreeing to  amendments  or  modifications  to any of the Loan  Documents or for
purposes of making requests to the Administrative Agent pursuant to ss.10 to the
extent that such  participation  is  beneficially  owned by the  Borrower or any
Affiliate of the Borrower, and the determination of the Majority Banks shall for
all  purposes of this  Agreement  and the other Loan  Documents  be made without

     Section 15.8. Miscellaneous Assignment Provisions. Any assigning Bank shall

United States of America or any state thereof, shall, prior to the date on which
any  interest  or fees are  payable  hereunder  or under any of the  other  Loan

that such Bank is entitled to receive  payments  under this Credit  Agreement or
any of the other Loan Documents  payable to it, without deduction or withholding

portion of its interest and rights under this Credit Agreement (including all or
any portion of its Notes) to any of the twelve Federal  Reserve Banks  organized
under  Section 4 of the  Federal  Reserve  Act, 12 U.S.C.  Section  341. No such

AND SHALL FOR ALL PURPOSES BE CONSTRUED IN  ACCORDANCE  WITH AND GOVERNED BY THE
LAWS OF SAID COMMONWEALTH  (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR CHOICE
OF LAW).  THE  BORROWER  CONSENTS TO THE  JURISDICTION  IN ANY OF THE FEDERAL OR
STATE COURTS LOCATED IN THE COMMONWEALTH OF MASSACHUSETTS IN CONNECTION WITH ANY
SUIT TO  ENFORCE  THE  RIGHTS  OF THE  BANKS AND THE  AGENT  UNDER  THIS  CREDIT
AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.

         Section 18.  HEADINGS.  The captions in this Credit Agreement are 
for convenience of reference only and shall not define or limit the provisions 
hereof.

         Section 19.  COUNTERPARTS.  This  Credit  Agreement  and any  amendment
hereof may be executed in several  counterparts  and by each party on a separate
counterpart,  each of which when so executed and delivered shall be an original,
and all of which  together  shall  constitute  one  instrument.  In proving this
Credit  Agreement  it shall not be necessary to produce or account for more than
one such counterpart signed by the party against whom enforcement is sought.

         Section 20.  ENTIRE  AGREEMENT,  ETC. The Loan  Documents and any other
documents  executed  in  connection  herewith  or  therewith  express the entire
understanding  of the  parties  with  respect to the  transactions  contemplated
hereby.  Neither  this  Credit  Agreement  nor any term  hereof may be  changed,
waived, discharged or terminated, except as provided in Section 22.

         Section 21.  WAIVER OF JURY TRIAL. The Borrower hereby waives its right
to a jury trial with  respect to any action or claim  arising out of any dispute
in connection with this Credit Agreement or any of the other Loan Documents, any
rights or obligations  hereunder or thereunder or the performance of such rights
and  obligations.  The Borrower (a) certifies that no  representative,  agent or
attorney of any Bank or the Administrative  Agent has represented,  expressly or
otherwise, that such Bank or the Administrative Agent would not, in the event of
litigation seek to enforce the foregoing waivers






                                     - 50 -


and (b)  acknowledges  that it has  been  induced  to  enter  into  this  Credit
Agreement  and the other Loan  Documents  by,  among  other  things,  the mutual
waivers and certifications contained herein.

         Section 22.  CONSENTS,  AMENDMENTS,  WAIVERS,  ETC. Except as otherwise
expressly provided in this Credit Agreement, any consent or approval required or
permitted by this Credit  Agreement  to be given by the Banks may be given,  and
any term of this Credit Agreement or of any other  instrument  related hereto or
mentioned  herein may be  amended,  and the  performance  or  observance  by the
Borrower of any terms of this Credit  Agreement or such other  instrument or the
continuance of any Default or Event of Default may be waived  (either  generally
or in a particular instance and either retroactively or prospectively) with, but
only with,  the written  consent of the Borrower and the written  consent of the
Majority Banks.  Notwithstanding  the foregoing,  (i) the term and the amount of
the  Commitments  of the Banks may not be changed,  (ii) the rate of interest on
the Loans and the amount of the Facility  Fee  hereunder  may not be  decreased,
(iii) the terms of Section 2.9 may not be changed without the written consent of
the Swing Line Bank and the Majority  Banks,  and (iv) the terms of this Section
22 may not be  changed  without  the  written  consent of the  Borrower  and the
written  consent of each of the Banks;  the  definition of Majority Banks or the
number of Banks  required  for any  consent  or  approval  hereunder  may not be
amended without the written  consent of each of the Banks;  and ss.11 may not be
amended  without the  written  consent of each of the  Agents.  No waiver  shall
extend to or affect  any  obligation  not  expressly  waived or impair any right
consequent thereon. No course of dealing or delay or omission on the part of any
Bank or Agent in  exercising  any right  shall  operate  as a waiver  thereof or
otherwise be prejudicial thereto. No notice to or demand upon the Borrower shall
entitle the  Borrower  to other or further  notice or demand in similar or other
circumstances.

     Section  23.  FCC  APPROVAL.   Notwithstanding  anything  to  the  contrary
contained in this Credit  Agreement or in the other Loan Documents,  neither the
Administrative  Agent  nor any  Bank  will  take  any  action  pursuant  to this
Agreement or any of the other Loan Documents which would constitute or result in
a change in control of the  Borrower or any of its  Subsidiaries  requiring  the
prior  approval of the FCC without first  obtaining  such prior  approval of the
FCC.  After the  occurrence of an Event of Default,  the Borrower  shall take or
cause to be taken any  action  which  the  Administrative  Agent may  reasonably
request in order to obtain  from the FCC such  approval as may be  necessary  to
enable  the  Administrative  Agent to  exercise  and enjoy the full  rights  and
benefits granted to the  Administrative  Agent, for the benefit of the Banks and
the  Agents,  by this  Credit  Agreement  or any of the  other  Loan  Documents,
including,  at the Borrower's  cost and expense,  the use of the Borrower's best
efforts to assist in  obtaining  such  approval  for any  action or  transaction
contemplated  by this Credit  Agreement or any of the other Loan  Documents  for
which such approval is required by law.

         Section 24.  SEVERABILITY.  The provisions of this Credit Agreement are
severable  and if any one clause or  provision  hereof  shall be held invalid or
unenforceable in whole or in part in any  jurisdiction,  then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such  jurisdiction,  and shall not in any manner affect such clause or provision
in any other  jurisdiction,  or any other  clause or  provision  of this  Credit
Agreement in any jurisdiction.

this   Credit   Agreement  or  otherwise,  by  a  Section  20  Subisdiary.
The  Borrower,  for  itself  and  each  of  its  Subsidiaries,   hereby
authorizes (a) such Section 20 Subsidiary to share with the Administrative Agent
and each Bank any  information  delivered to such Section 20  Subsidiary  by the
Borrower or any of its Subsidiaries,  and (b) the Administrative  Agent and each
Bank to share with such Section 20 Subsidiary any  information  delivered to the
Administrative  Agent or such Bank by the  Borrower  or any of its  Subsidiaries
pursuant to this Credit  Agreement,  or in connection  with the decision of such
Bank to enter into this Credit  Agreement;  it being  understood,  in each case,
that any such Section 20 Subsidiary receiving such information shall be bound by
the  confidentiality  provisions of this Credit  Agreement.  Such  authorization
shall survive the payment and satisfaction in full of all of Obligations.

         Section 25.2.  Confidentiality.   Each  of  the  Banks  and  the 
Agent  agrees  to  keep  any  non-public  information   delivered   or   made
available  to  it  pursuant  to  this  Credit  Agreement  or  any  other
Loan  Document  confidential   from  any  Person  other  than   officers,
employees,  agents,  accountants,  professional advisors,  counsel, designees or
representatives  of such  Bank or the Agent  who are or are  expected  to become
engaged in  evaluating,  approving,  structuring  or  administering  this Credit
Agreement or any of the other Loan  Documents;  provided,  that,  nothing herein

assignee or participant (or prospective assignee or participant) so long as such
assignee or  participant  agrees to be bound by the  provisions of Section 15.6,
(ii) to any of its  Affiliates  to the extent any such  Affiliates  require such
information  in the  ordinary  course  of the  Agent's  or  such  Bank's  credit

any governmental  authority or representative thereof or pursuant to subpoena or
other  legal  process,  by  virtue  of any  other  law,  regulation,  order,  or
interpretation,  (iv) to the  Administrative  Agent,  any Bank or any Section 20
Subsidiary,  (v) in connection  with any  litigation to which any one or more of
the Banks, the Administrative  Agent or any Section 20 Subsidiary is a party, or
in connection with the enforcement of rights or remedies  hereunder or under any
other Loan  Document,  and (vi) to a  Subsidiary  or  Affiliate  of such Bank as
provided in Section 25.1 or as required in  connection  with the exercise of any
remedy under this Credit Agreement or any of the other Loan Documents.

         Section 25.3.  Prior Notification.  Unless specifically prohibited
by  applicable  law  or  court  order,  each  of  the  Banks  and  the 
Administrative  Agent  shall,  prior to  disclosure  thereof,   notify  the 
Borrower  of  (i)  any  proposed  or  required  disclosure  of  any  such
non-public  information  pursuant to clauses (iii) or (v) of Section 25.2,
and (ii) any request for  disclosure of any such  non-public  information by any
governmental  agency or  representative  thereof (other than any such request in
connection  with an examination of the financial  condition of such Bank by such
governmental agency).

         Section 25.4. Other.  In  no  event  shall  any  Bank  or  Agent  be 
obligated  or  required  to  return  any  materials  furnished  to  it  or
any  Section  20  Subsidiary  by  the  Borrower  or  any  of  its 
Subsidiaries.   The  obligations  of  each  Bank  under  this  Section  25 
shall supersede and replace the  obligations  of such Bank under any  
confidentiality  letter in respect of this  financing  signed and  delivered  by
such Bank to the  Borrower prior to the date hereof and shall be binding upon 
any assignee of, or purchaser of any participation in, any interest in any of 
the Loans from any Bank.
