may use the Facility B  Commitments  by  borrowing,  prepaying  the  Revolving B
Credit Loans in whole or in part, and  reborrowing,  all in accordance  with the
terms and conditions hereof.

                  (c) The Loans may from time to time be (i)  Eurodollar  Loans,
(ii) Prime Rate  Loans or (iii) a  combination  thereof,  as  determined  by the
Borrowers and notified to the Agent in accordance with  subsections 2.2 and 4.8,
provided  that no Loan shall be made as a Eurodollar  Loan after the day that is
one month prior to the Maturity Date.

                  2.2 Procedure for  Borrowing.  A Borrower may borrow under the
Commitments during the Commitment Period on any Business Day, provided that such
Borrower  shall  deliver  to the  Agent  the  Borrower's  irrevocable  Notice of
Borrowing which notice must be in writing or by telephone  promptly confirmed in
writing  prior to 10:00 A.M.,  Charlotte,  North  Carolina  time,  (a) three (3)
Business Days prior to the requested  borrowing  date, if all or any part of the
requested  Loans are to be initially  Eurodollar  Loans or (b) on the  requested
borrowing date,  otherwise.  Upon receipt of any such Notice of Borrowing from a
Borrower,  the Agent shall promptly notify each Lender thereof. Each Lender will
make the amount of its pro rata share of each  borrowing  available to the Agent
for the  account  of such  Borrower  at the  office  of the Agent  specified  in
subsection  11.3 prior to 12:00  P.M.,  Charlotte,  North  Carolina  time on the
borrowing date, in funds immediately available to the Agent. Such borrowing will
then be made available to such Borrower by the Agent  transferring to an account
(which shall be maintained  for such purpose by the Agent) with the aggregate of
the  amounts  made  available  to the Agent by the  Lenders and in like funds as
received by the Agent.

                  2.3      Use of Proceeds of Loans.

                  (a) The  proceeds of the Facility A Loans shall be utilized by
the Borrowers (i) to finance future acquisitions  permitted  hereunder,  (ii) to
provide working capital and (iii) for other general corporate purposes.

                  (b) The  proceeds of the Facility B Loans shall be utilized by
the Borrowers to finance future acquisitions permitted hereunder.

         SECTION 3.  AMOUNT AND  TERMS OF LETTER OF CREDIT SUB-FACILITY
                  3.1      L/C Commitment.

                  (a) Subject to the terms and conditions  hereof,  each Issuing
Bank, in reliance on the agreements of the other Lenders set forth in subsection
3.4(a) agrees to issue any Letters of Credit requested to be issued by it and so
issued by it for the account of the  Borrowers  on any  Business  Day during the
Facility A Commitment  Period in such form as may be approved  from time to time
by such Issuing  Bank;  provided that such Issuing Bank shall have no obligation
to issue any Letter of Credit if, after  giving  effect to such  issuance,  such
Issuing Bank has  knowledge  that (i) the L/C  Obligations  would exceed the L/C
Commitment, or (ii) the Available Facility A Commitment would be less than zero.





                  (b)      Each Letter of Credit shall:

                           (i)  be either (A) a standby letter of credit issued 
to support  obligations  of the  Borrowers and the  Subsidiaries,  contingent or
otherwise, for which Loans would be available (a "Standby Letter of Credit"), or
(B) a commercial  letter of credit issued in respect of the purchase of goods or
services  by the  Borrowers  and the  Subsidiaries  in the  ordinary  course  of
business for which Loans would be available (a "Commercial Letter of Credit");

                           (ii) be (A) issued from an office of the Issuing Bank
in the United States and (B)
denominated in Dollars; and

                           (iii) expire no later than the earlier of (A) one (1)
year following the date of issuance
thereof  and (B) five (5) days prior to the  Maturity  Date;  provided  that any
Letter of Credit may provide for renewal thereof for additional one-year periods
on an "evergreen"  basis (but not, in any event,  beyond the date referred to in
clause (B) of this subparagraph (iii)).

                  (c) Each  Letter of Credit  shall be  subject  to the  Uniform
Customs  and,  to  the  extent  not  inconsistent  therewith,  the  laws  of the
Commonwealth of Virginia.

                  (d) No Issuing  Bank shall at any time be  obligated  to issue
any Letter of Credit  hereunder if such issuance  would  conflict with, or cause
such Issuing Bank or any L/C  Participant  to exceed any limits  imposed by, any
applicable Requirement of Law.

                  3.2 Procedure for Issuance of Letters of Credit. The Borrowers
shall  request that such Issuing Bank issue a Letter of Credit by  delivering to
such Issuing  Bank at its address for notices  specified  herein an  Application
therefor,  completed to the  satisfaction  of the Issuing  Bank,  and such other
certificates, documents and other papers and information as the Issuing Bank may
request.  Upon  receipt of any  Application,  the Issuing Bank will process such
Application  and the  certificates,  documents and other papers and  information
delivered  to it in  connection  therewith  in  accordance  with  its  customary
procedures and shall promptly  issue the Letter of Credit  requested  thereby by
issuing the original of such Letter of Credit to the  beneficiary  thereof or as
otherwise may be agreed by the Issuing Bank and the Borrowers; provided that the
Issuing Bank shall in no event be required to issue any Letter of Credit earlier
than three (3) Business Days after its receipt of the  Application  therefor and
all such other certificates, documents and other papers and information relating
thereto. In the event that the Letter of Credit to be issued is a Standby Letter
of Credit,  the  Issuing  Bank shall  furnish a copy of such  Standby  Letter of
Credit to each of the Agent and the  Borrowers  promptly  following the issuance
thereof.

                  3.3      Fees, Commissions and Other Charges.

         (a) The Borrowers,  jointly and severally,  shall pay to the Agent, for
the account of each Issuing Bank and the L/C Participants,  with respect to each
Commercial Letter of Credit




issued  by such  Issuing  Bank a fee in an  amount  equal to 1% per annum on the
amount  available to be drawn under each Commercial  Letter of Credit payable on
the  date of  issuance  of  such  Commercial  Letter  of  Credit  and  shall  be
nonrefundable.

                  (b) The  Borrowers,  jointly and  severally,  shall pay to the
Agent, for the account of each Issuing Bank and the L/C  Participants,  a letter
of credit  commission  with respect to each Standby  Letter of Credit  issued by
such Issuing Bank,  computed for each day during the period for which payment is
due at the rate per annum  equal to the  Applicable  Margin for the  Facility in
effect for Eurodollar  Loans on such date  (calculated on the basis of a 360 day
year) times the aggregate amount available to be drawn under such Standby Letter
of Credit on such date. Such commissions shall be payable quarterly, in advance,
on each L/C Fee Payment Date and shall be nonrefundable.

                  (c) The  Borrowers,  jointly and  severally,  shall pay to the
relevant Issuing Bank, for its own account a fronting fee in the amount equal to
1/4 of 1% per annum on the face amount of each Standby  Letter of Credit  issued
by it. The fronting fee shall be  calculated  on the basis of a 360 day year and
shall be payable quarterly, in advance, on each L/C Fee Payment Date.

                  (d) In addition to the  foregoing  fees and  commissions,  the
Borrowers,  jointly and severally,  shall pay or reimburse each Issuing Bank for
such normal and customary  costs and expenses as are incurred or charged by such
Issuing  Bank  issuing,   effecting   payment   under,   amending  or  otherwise
administering any Letter of Credit issued by it.

                  (e) The Agent shall,  promptly  following its receipt thereof,
distribute to the relevant  Issuing Bank and the L/C  Participants  all fees and
commissions received by the Agent for their respective accounts pursuant to this
subsection 3.3.

                  3.4      L/C Participations.

                  (a) Each Issuing Bank  irrevocably  agrees to grant and hereby
grants to each L/C  Participant,  and,  to  induce  such  Issuing  Bank to issue
Letters of Credit hereunder,  each L/C Participant  irrevocably agrees to accept
and purchase and hereby  accepts and  purchases  from the Issuing  Bank,  on the
terms and conditions  hereinafter stated, for such L/C Participant's own account
and  risk an  undivided  interest  equal to such  L/C  Participant's  Commitment
Percentage  in the Issuing  Bank's  obligations  and rights under each Letter of
Credit  issued by it hereunder  and the amount of each draft paid by the Issuing
Bank thereunder.  Each L/C Participant  unconditionally  and irrevocably  agrees
with such Issuing  Bank that,  if a draft is paid under any Letter of Credit for
which such Issuing Bank is not reimbursed in full by the Borrowers in accordance
with the terms of this Agreement, such L/C Participant shall pay to such Issuing
Bank  (through the Agent) upon demand an amount equal to such L/C  Participant's
Commitment Percentage of the amount of such draft, or any part thereof, which is
not so reimbursed.

                  (b) If any amount  required to be paid by any L/C  Participant
to an Issuing Bank pursuant to paragraph  3.4(a) in respect of any  unreimbursed
portion of any payment made by such




Issuing  Bank  under any Letter of Credit  issued by it is paid to such  Issuing
Bank within three (3) Business Days after the date such payment is due, such L/C
Participant  shall pay to such  Issuing  Bank  (through  the Agent) on demand an
amount  equal to the product of (i) such  amount,  times (ii) the daily  average
Federal Funds Effective Rate, as quoted by such Issuing Bank,  during the period
from and  including  the date such payment is required to the date on which such
payment is  immediately  available to such Issuing Bank,  times (iii) a fraction
the  numerator of which is the number of days that elapse during such period and
the  denominator of which is 360. If any such amount  required to be paid by any
L/C  Participant  pursuant to paragraph  4.4(a) is not in fact made available to
such Issuing Bank by such L/C  Participant  within three (3) Business Days after
the date such  payment is due,  such  Issuing  Bank shall be entitled to recover
from  such L/C  Participant,  on  demand,  such  amount  with  interest  thereon
calculated  from such due date at the rate per annum  applicable  to Prime  Rate
Loans  hereunder.  A  certificate  of such  Issuing  Bank  submitted  to any L/C
Participant  (through the Agent)  shall,  to the extent  permitted by applicable
law, be prima facie evidence of any amounts owing under this subsection 3.4.

                  (c)  Whenever,  at any  time  after an  Issuing  Bank has made
payment under any Letter of Credit and has received from any L/C Participant its
pro rata share of such  payment  in  accordance  with  subsection  3.4(a),  such
Issuing  Bank  receives  any payment  related to such Letter of Credit  (whether
directly  from the  Borrowers or  otherwise,  including  proceeds of  collateral
applied  thereto by such  Issuing  Bank),  or any payment of interest on account
thereof, such Issuing Bank will distribute to the Agent (for the account of such
L/C  Participant)  such L/C  Participant's  pro rata  share  thereof;  provided,
however,  that in the event that any such payment  received by such Issuing Bank
shall be  required to be returned by such  Issuing  Bank,  such L/C  Participant
shall  return to such  Issuing  Bank  (through  the Agent) the  portion  thereof
previously distributed by such Issuing Bank to it.

                  3.5      Reimbursement Obligation of the Borrowers.

                  (a) The Borrowers,  jointly and severally,  agree to reimburse
each Issuing Bank on each date on which such Issuing Bank notifies the Borrowers
of the date and amount of a draft presented under any Letter of Credit issued by
such Issuing Bank and paid by such Issuing Bank for the amount of (i) such draft
so paid and (ii) any taxes, fees, charges or other costs or expenses incurred by
the Lenders in connection with such payment.  Each such payment shall be made to
such Issuing Bank at its address for notices  specified herein in Dollars and in
immediately available funds.

                  (b) Interest shall be payable on any and all amounts remaining
unpaid by the  Borrowers  under this  subsection  3.5 from the date such amounts
become payable (whether at stated maturity,  by acceleration or otherwise) until
payment in full at the rate which would be payable on any outstanding Prime Rate
Loans which were then overdue.

                  (c) Each drawing  under any Letter of Credit shall  (unless it
is reimbursed  by the Borrowers on the date of drawing)  constitute a request by
the Borrowers to the Agent for a




borrowing pursuant to subsection 2.2 of Prime Rate Loans under Facility A in the
amount of such drawing.  The borrowing date with respect to such borrowing shall
be the date of such drawing.

                  3.6      Obligations Absolute.

                  (a) The Borrowers'  obligations  under this Section 3 shall be
absolute and  unconditional  under any and all circumstances and irrespective of
any set-off,  counterclaim  or defense to payment which any Borrower may have or
have had against any Issuing Bank or any beneficiary of a Letter of Credit.

                  (b) The Borrowers  also agree with each Issuing Bank that such
Issuing  Bank shall not be  responsible  for, and the  Borrowers'  Reimbursement
Obligations  under  subsection  3.5(a)  shall not be  affected  by,  among other
things,  (i) the validity or  genuineness  of  documents or of any  endorsements
thereon,  even  though  such  documents  shall  in  fact  prove  to be  invalid,
fraudulent or forged,  or (ii) any dispute between or among any Borrower and any
beneficiary  of any Letter of Credit or any other  party to which such Letter of
Credit may be transferred or (iii) any claims whatsoever of any Borrower against
any beneficiary of such Letter of Credit or any such transferee.

                  (c) No Issuing  Bank shall be liable for any error,  omission,
interruption  or delay in  transmission,  dispatch or delivery of any message or
advice,  however transmitted,  in connection with any Letter of Credit issued by
such Issuing Bank,  except for errors or omissions caused by such Issuing Bank's
gross negligence or willful misconduct.

                  (d) The Borrowers agree that any action taken or omitted by an
Issuing  Bank under or in  connection  with any Letter of Credit or the  related
drafts or  documents,  if done in the  absence  of gross  negligence  or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial  Code of the  Commonwealth  of  Virginia,  shall  be  binding  on the
Borrowers  and shall not result in any  liability  of such  Issuing  Bank to the
Borrowers.

                  (e) Notwithstanding the foregoing, in the event a Bank Default
exists,  the  Issuing  Bank shall not be  required to issue any Letter of Credit
unless the Issuing Bank has entered into arrangements satisfactory to it and the
Borrowers to eliminate the Issuing  Bank's  additional  risk with respect to the
participation  in the Letters of Credit of the  Defaulting  Lender or Defaulting
Lenders, including,  without limitation, by cash collateralizing such Defaulting
Lender or Lender's  Commitment  Percentage  of the  applicable  outstanding  L/C
Obligations or by a Non-Defaulting  Lender or  Non-Defaulting  Lenders replacing
such Defaulting Lender or Defaulting Lenders with respect to such participation.

                  3.7  Letter of Credit  Payments.  The  responsibility  of each
Issuing Bank to the Borrowers in connection with any draft presented for payment
under  any  Letter  of Credit  shall,  in  addition  to any  payment  obligation
expressly provided for in such Letter of Credit, be limited to




determining  that the  documents  (including  each draft)  delivered  under such
Letter of Credit in connection with such presentment are in conformity with such
Letter of Credit.

                  3.8  Application.  To the  extent  that any  provision  of any
Application  related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

         SECTION 4.   PROVISIONS RELATING TO THE EXTENSIONS OF CREDIT; FEES AND 
                      PAYMENTS.

                  4.1      Repayment of Loans; Evidence of Debt.

                  (a)   The   Borrowers,    jointly   and   severally,    hereby
unconditionally  promise to pay to the Agent for the account of each  applicable
Lender (i) the then unpaid  principal  amount of each Loan on the Maturity  Date
(or such  earlier  date on which the Loans  become due and  payable  pursuant to
Section 9). The Borrowers,  jointly and  severally,  hereby further agree to pay
interest  on the  unpaid  principal  amount  of the  Loans  from  time  to  time
outstanding  from the date hereof until payment in full thereof at the rates per
annum, and on the dates, set forth in subsection 4.10.

                  (b) Each Lender shall  maintain in  accordance  with its usual
practice an account or accounts  evidencing  debt of the Borrowers to the Lender
resulting from each Loan of such Lender from time to time, including the amounts
of  principal  and  interest  payable  and paid to such Lender from time to time
under this Agreement.

                  (c)  The  Agent  shall  maintain  the  Register   pursuant  to
subsection  11.8(d) and a subaccount  therein for each Lender, in which shall be
recorded  (i) the  amount  of each  Facility  A Loan and  Facility  B Loan  made
hereunder,  the Type thereof and each Interest Period applicable  thereto,  (ii)
the amount of any  principal  or  interest  due and payable or to become due and
payable from the Borrowers to the Lenders  hereunder and (iii) the amount of any
sum received by the Agent hereunder from the Borrowers.

                  (d) The entries  made in the Register and the accounts of each
Lender maintained  pursuant to subsection 11.8(d) shall, to the extent permitted
by applicable  law, be prima facie  evidence of the existence and amounts of the
obligations  of the Borrowers  therein  recorded;  provided,  however,  that the
failure of any Lender or the Agent to maintain the Register or any such account,
or any error therein,  record or any error in any record shall not in any manner
affect the obligation of the Borrowers to repay (with  applicable  interest) the
Loans made to the Borrowers by the Lenders in accordance  with the terms of this
Agreement.

                  (e) The  Borrowers  agree  that,  upon  request  of any Lender
through the Agent,  the Borrowers  will execute and deliver to such Lender (i) a
promissory note of the Borrowers evidencing the Facility A Loan of the Lender to
the  Borrowers,  substantially  in the form of Exhibit A ("Facility A Note") and
(ii) a promissory  note of the Borrowers  evidencing  the Facility B Loan of the
Lender to the  Borrowers,  substantially  in the form of Exhibit B  ("Facility B
Note").

                  4.2      Facility Fees.

                  (a) The Borrowers,  jointly and severally, agree to pay to the
Agent,  for the  account of each  Lender,  the (i)  Facility A Fees and (ii) the
Facility B Fees (the "Facility Fees").

                  (b) Such  Facility  Fees shall be calculated on the basis of a
365/366 day year as the case may be.

                  (c) Such  Facility  A Fees  shall  be  payable  quarterly,  in
arrears,  on the last Business Day of each June,  September,  December and March
and the Maturity Date or such earlier date as the Facility A  Commitments  shall
terminate as provided herein, commencing on June 30, 1998.

                  (d) Such Facility B Fees shall be payable,  in advance,  on or
before each borrowing date of a Borrower under Facility B.

                  4.3      Optional Prepayments.

                  (a) The Borrowers may at any time and from time to time prepay
the Prime Rate Loans, in whole or in part,  without premium or penalty,  subject
to the provisions of 4.6.

                  (b) The  Borrowers,  with the  consent of the Agent  (which in
each case shall not be unreasonably withheld),  may at any time and from time to
time  prepay  the  Eurodollar  Loans,  in whole or in part,  without  premium or
penalty  (subject to the provisions of subsections 4.7 and 4.17),  upon at least
three (3) Business  Days' notice to the Agent (which  notice must be received by
the Agent prior to 11:00 A.M., Charlotte,  North Carolina time, on the date upon
which such notice is due and shall be  irrevocable  by the  Borrowers  except in
connection with prepayments that are contingent on Net Proceeds to the extent of
such contingency) specifying the date and amount of prepayment.  Upon receipt of
any such notice,  the Agent shall promptly  notify each Lender and the Borrowers
of its  consent or its  rejection  thereof.  If any such  notice is given by the
Borrowers  and not  withdrawn  or  rejected  prior to the date upon  which  such
payment is made, the amount specified in such notice shall be due and payable on
the date  specified  therein,  together  with any  amounts  payable  pursuant to
subsection 4.17.

                  (c) Partial  prepayments  shall be in an  aggregate  principal
amount of  $100,000  or an  integral  multiple  thereof  or in the amount of the
outstanding Loans.

                  (d) For so long as no Default or Event of Default has occurred
and is continuing, the Borrowers may elect the application of prepayments to the
Facilities  made  pursuant  to this  subsection  4.3,  provided  that unless the
Borrowers  otherwise elect,  the application of prepayments  under each Facility
made pursuant to this  subsection  4.3 shall be made,  first,  to Prime Rate and
second, to Eurodollar Loans.

                  4.4 Optional  Termination  or Reduction  of  Commitments.  The
Borrowers  shall have the right,  upon not less than  three (3)  Business  Days'
notice to the Agent,  to terminate  the  Commitments  or, from time to time,  to
reduce  the  amount of the  Commitments;  provided  that with  respect to either
Facility A or Facility B, no such  termination  or reduction  shall be permitted
with respect to the Commitments of such Facility to the extent that after giving
effect  thereto  and to any  prepayments  of the Loans  made  thereunder  on the
effective  date  thereof,  the  aggregate  principal  amount of such  Loans then
outstanding when added to the then outstanding L/C Obligations, would exceed the
Commitments  then in effect.  Any such reduction  shall be in an amount equal to
$100,000 or an integral multiple in excess thereof and shall reduce  permanently
the affected Commitments then in effect.

                  4.5      Mandatory Reduction of Commitments and Prepayments.

                  (a) If at any time the  Facility  A  Aggregate  Extensions  of
Credit  for all  Lenders  exceed  the  lesser  of the  Loan  Value  of  Eligible
Receivables and the aggregate Facility A Commitments, the Borrowers, jointly and
severally, shall immediately repay the aggregate Facility A Loans and/or deposit
in the L/C  Collateral  Account an amount  equal to the amount that may be drawn
under  outstanding  Letters of Credit (whether or not the  beneficiaries  of the
then outstanding  Letters of Credit shall have presented the documents  required
thereunder),  such repayments and deposits to be in an aggregate amount equal to
such excess.

                  (b)  If at any  time  the  Facility  B  Aggregate  Outstanding
Extensions of Credit of all Lenders exceed the aggregate Facility B Commitments,
the Borrowers,  jointly and severally,  shall  immediately  repay the Facility B
Loans, such repayments to be in an aggregate amount equal to such excess.

                  (c) The Borrowers, jointly and severally, shall as promptly as
is  practicable  (and,  in any event,  within one (1) Business Day following the
receipt  thereof),  repay the  Facility A Loans,  repay the Facility B Loans and
reduce the Facility B Commitments by the amount equal to the aggregate amount of
Net  Proceeds  received  from  any Net  Proceeds  Event;  provided  that no such
repayment and  reduction  shall be due pursuant to this  subsection  4.5(c) with
respect to any Net Proceeds Event on account of:

                           (i) the  sale,  transfer  or other  disposition  by a
         Borrower or any of its  Subsidiaries of any real or personal,  tangible
         or  intangible,  property of a Borrower  and its  Subsidiaries,  to the
         extent  that  the Net  Proceeds  from  such  sale,  transfer  or  other
         disposition  (in the  aggregate  with the Net  Proceeds  from all other
         sales,  transfers and other  dispositions  occurring  during the fiscal
         year) is less than $250,000; or

                           (ii) the  recovery by a Borrower of amounts  owing to
         it under property  insurance  policies  except,  to the extent that (1)
         such recoveries  exceed the reasonably  estimated cost of replacing the
         property on account of which such  amounts  were paid to such  Borrower
         and its  Subsidiaries or (2) such Borrower and its  Subsidiaries do not
         replace such property within one hundred eighty (180) days.

                  (d)  Any  payments  of  the  Loans  and   reductions   of  the
Commitments made pursuant to subsection 4.5(c) shall be applied, first, to repay
the  Facility B Loans and to reduce the  Facility  B  Commitments  and second to
repay  the  Facility  A  Loans.   Unless  the  Borrowers  otherwise  elect,  the
application of prepayments  under each Facility made pursuant to this subsection
4.5 shall be made, first, to Prime Rate Loans and second, to Eurodollar Loans.

                  4.6  Application  of  Payments.  Any payments of the Loans and
reductions of the Commitments made pursuant to subsections 4.3, 4.4 or 4.5 shall
not be applied to the prepayment of the Loans of a Defaulting Lender at any time
under the  Facility  when the  aggregate  amount of Loans of any  Non-Defaulting
Lender exceeds such Non-Defaulting  Lender's Commitment  Percentage of all Loans
then outstanding.

                  4.7 Prepayment Premium. If any Borrower prepays any portion of
the Loans with the proceeds of a loan from a commercial bank, finance company or
other lender of a type that is a competitor of the Agent, the Borrowers, jointly
and  severally,  shall pay to the Agent,  not later than the next  Business  Day
after the date of such prepayment, a prepayment premium of 1% on any outstanding
obligations so repaid.

                  4.8      Conversion and Continuation Options.

                  (a) A  Borrower  may  elect  from  time  to  time  to  convert
Eurodollar  Loans to Prime Rate Loans by delivering to the Agent an  irrevocable
Notice of  Borrowing  by 10:00 A.M.,  Charlotte,  North  Carolina  time,  on the
requested  date of conversion;  provided that any such  conversion of Eurodollar
Loans  may only be made on the  last  day of an  Interest  Period  with  respect
thereto.  A Borrower may elect from time to time to convert  Prime Rate Loans to
Eurodollar  Loans by delivering to the Agent an irrevocable  Notice of Borrowing
by 10:00 A.M., Charlotte,  North Carolina time, at least three (3) Business Days
prior to the  requested  conversion  date.  Any such  Notice of  Borrowing  with
respect to a  conversion  to  Eurodollar  Loans shall  specify the length of the
initial Interest Period or Interest Periods  therefor.  Upon receipt of any such
Notice of Borrowing the Agent shall promptly notify each Lender thereof.  All or
any part of outstanding  Eurodollar  Loans and Prime Rate Loans may be converted
as provided herein, provided that (i) no Loan may be converted into a Eurodollar
Loan when any Default or Event of Default has occurred and is continuing and the
Agent has or the Majority  Lenders have determined that such a conversion is not
appropriate  and (ii) no Loan may be converted into a Eurodollar  Loan after the
date that is one (1) month prior to the Maturity  Date.  Any Prime Rate Loan not
converted to a Eurodollar Loan hereunder shall continue as an Prime Rate Loan.

                  (b) Any  Eurodollar  Loans may be  continued  as such upon the
expiration  of the then  current  Interest  Period  with  respect  thereto  by a
Borrower  delivering  to the  Agent  an  irrevocable  Notice  of  Borrowing,  in
accordance  with the  applicable  provisions of the term  "Interest  Period" set
forth in  subsection  1.1,  of the  length  of the next  Interest  Period  to be
applicable to such Loans,  provided that no Eurodollar  Loan may be continued as
such (i) when any Event of Default has occurred and is continuing  and the Agent
has or the Majority  Lenders have  determined  that such a  continuation  is not
appropriate  or (ii) after the date that is one (1) month prior to the  Maturity
Date, and provided,  further,  that if a Borrower shall fail to give such notice
or if such  continuation  is not  permitted  such Loans  shall be  automatically
converted to Prime Rate Loans




on the last day of such then expiring Interest Period.  Upon receipt of any such
Notice of Borrowing the Agent shall promptly notify each Lender thereof.

                  4.9      Minimum Amounts and Maximum Number of Tranches.

                  (a)  All   borrowings,   conversions  and   continuations   of
Eurodollar  Loans  hereunder and all  selections of Interest  Periods  hereunder
shall be in such amounts and be made pursuant to such  elections so that,  after
giving effect thereto,  the aggregate  principal  amount of the Eurodollar Loans
comprising each Tranche shall be equal to $100,000 or a whole multiple in excess
thereof.  In no event shall there be more than ten (10)  Tranches of  Eurodollar
Loans outstanding at any time.

                  (b)  All   borrowings  and  repayments  of  Prime  Rate  Loans
hereunder  shall be in such amounts so that,  after giving effect  thereto,  the
aggregate principal amount of the Prime Rate Loans shall be equal to $100,000 or
a whole  multiple  in  excess  thereof,  or if  less,  the  remaining  available
Commitments hereunder.

                  4.10     Interest Rates and Payment Dates.

                  (a) Each  Eurodollar  Loan  shall bear  interest  for each day
during each  Interest  Period with respect  thereto at a rate per annum equal to
the Eurodollar Rate determined for such day plus the Applicable Margin in effect
for such day.

                  (b) Each Prime Rate Loan shall bear interest for each day at a
rate per annum equal to the Prime Rate plus the Applicable  Margin in effect for
such day.

                  (c) If all or a portion of any principal of any Loan shall not
be paid when due (whether at the stated maturity, by acceleration or otherwise),
such principal  amount of the Loan shall bear interest at a rate per annum which
is the rate that would otherwise be applicable thereto pursuant to the foregoing
provisions of this subsection 4.10(c) plus 2%.

                  (d)  Interest on each Loan shall be payable in arrears on each
Interest Payment Date provided that interest  accruing pursuant to paragraph (c)
of this subsection 4.10 shall be payable from time to time on demand.

                  (e) Notwithstanding anything to the contrary contained herein,
in no event shall the  Borrowers  be  obligated to pay interest in excess of the
maximum amount which is chargeable under applicable law.

                  4.11     Computation of Interest and Facility Fees.

                  (a)      Facility Fees shall be calculated in accordance with 
subsection 4.2.





                  (b)  Interest  shall be  calculated  on the basis of a 360-day
year for the actual days elapsed.  The Agent shall as soon as practicable notify
the Borrowers and the Lenders of each  determination  of a Eurodollar  Rate. Any
change in the interest rate on a Loan  resulting from a change in the Prime Rate
or the  Eurocurrency  Reserve  Requirements  shall  become  effective  as of the
opening of business on the day on which such change becomes effective.

                  (c)  Each  determination  of an  interest  rate  by the  Agent
pursuant to any provision of this  Agreement  shall be conclusive and binding on
the Borrowers and the Lenders in the absence of manifest error. The Agent shall,
at the request of the  Borrowers,  deliver to the Borrowers a statement  showing
the quotations  used by the Agent in  determining  any interest rate pursuant to
subsection 4.10(a).

                  4.12     Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                  (a) the Agent shall have determined (which determination shall
be conclusive  and binding upon the Borrowers in the absence of manifest  error)
that, by reason of  circumstances  affecting the relevant  market,  adequate and
reasonable  means do not exist for  ascertaining  the  Eurodollar  Rate for such
Interest Period; or

                  (b) the Agent shall have  received  notice  from the  Majority
Lenders  that  the  Eurodollar  Rate  determined  or to be  determined  for such
Interest  Period will not adequately and fairly reflect the cost to such Lenders
(as  conclusively  certified by such Lenders),  of making or  maintaining  their
affected Loans during such Interest Period;

the Agent shall give telecopy or telephonic  notice thereof to the Borrowers and
the Lenders as soon as practicable  thereafter.  If such notice is given (x) any
Eurodollar  Loans  requested to be made on the first day of such Interest Period
shall be made as Prime  Rate  Loans and (y) any  Loans  that on the first day of
such Interest Period were to have been continued as, or converted to, Eurodollar
Loans shall be converted to or continued as Prime Rate Loans.  Until such notice
has been withdrawn by the Agent, no further  Eurodollar  Loans shall be made, or
as of the first day of the immediately succeeding Interest Period,  continued as
such,  nor shall any  Borrower  have the right to  convert  Loans to  Eurodollar
Loans. .

                  4.13 Pro Rata  Treatment  and  Payments.  Each  borrowing by a
Borrower  from the Lenders  hereunder,  each payment by a Borrower on account of
any Facility Fee hereunder and any reduction of the  Commitments  of the Lenders
shall  be  made  pro  rata  according  to  the  respective  relevant  Commitment
Percentages of the Lenders holding  obligations in respect of which such amounts
were paid. Each payment  (including each prepayment) by a Borrower on account of
principal of and (subject to the provisions of subsection  4.14) interest on the
Loans shall be made pro rata according to the respective  outstanding  principal
amounts of such Loans then held by the Lenders.  Except as  otherwise  set forth
herein,  all  payments  (including  prepayments)  to be  made  by the  Borrowers
hereunder,  whether on account of principal,  interest, fees or otherwise, shall
be made without set off or counterclaim




and shall be made prior to 2:00 P.M., Charlotte, North Carolina time, on the due
date thereof to the Agent,  for the account of the  applicable  Lenders,  at the
Agent's  office  specified in  subsection  11.3,  in Dollars and in  immediately
available funds. The Agent shall distribute such payments to the Lenders holding
obligations  on account of which such amounts were paid promptly upon receipt in
like funds as received.  If any payment  hereunder  becomes due and payable on a
day other  than a Business  Day,  such  payment  shall be  extended  to the next
succeeding  Business Day,  and, with respect to payments of principal,  interest
thereon shall be payable at the then applicable rate during such extension.

                  (b) Unless the Agent  shall have been  notified  in writing by
any Lender  prior to a borrowing  that such Lender will not make the amount that
would constitute its relevant Commitment  Percentage of such borrowing available
to the  Agent,  the Agent may  assume  that such  Lender is making  such  amount
available  to the Agent,  and the Agent may, in reliance  upon such  assumption,
make available to the Borrowers a  corresponding  amount.  If such amount is not
made available to the Agent by the required time on the borrowing date therefor,
such Lender shall pay to the Agent, on demand, such amount with interest thereon
at a rate equal to the daily average Federal Funds Effective Rate for the period
until such  Lender  makes such  amount  immediately  available  to the Agent.  A
certificate of the Agent submitted to any Lender shall, to the extent  permitted
by  applicable  law,  be prima facie  evidence  of any amounts  owing under this
subsection  4.13.  If  such  Lender's  relevant  Commitment  Percentage  of such
borrowing  is not made  available  to the Agent by such Lender  within three (3)
Business  Days of such  borrowing  date,  the Agent  shall also be  entitled  to
recover such amount with  interest  thereon at the rate per annum  applicable to
Prime  Rate  Loans  hereunder,  on  demand,  jointly  and  severally,  from  the
Borrowers.

                  4.14 Illegality.  Notwithstanding  any other provision herein,
if  the  adoption  of or  any  change  in  any  Requirement  of  Law  or in  the
interpretation  or  application  thereof,  in each case after the Closing  Date,
shall make it unlawful  for any Lender to make or maintain  Eurodollar  Loans as
contemplated by this Agreement,  (a) the commitment of such Lender  hereunder to
make Eurodollar Loans,  continue Eurodollar Loans as such and convert Prime Rate
Loans to Eurodollar Loans shall forthwith be suspended and (b) the Loans of such
Lender  then  outstanding  as  Eurodollar  Loans,  if any,  shall  be  converted
automatically  to Prime  Rate  Loans  on the  respective  last  days of the then
current  Interest  Periods  with  respect to such Loans or within  such  earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto,  the Borrowers,  jointly and  severally,  shall pay to such Lender such
amounts, if any, as may be required pursuant to subsection 4.17.

                  4.15     Requirements of Law.
I
         (a) If the  adoption of or any change in any  Requirement  of Law or in
the  interpretation or application  thereof or compliance by any Lender with any
request or  directive  (whether or not having the force of law) from any central
bank or other Governmental  Authority, in each case, made subsequent to the date
hereof:





                           (i) shall  subject  any Lender to any tax of any kind
         whatsoever  with  respect to this  Agreement,  any Note,  any Letter of
         Credit,  any  Application or any Eurodollar  Loan made by it, or change
         the basis of taxation  of  payments  to such Lender in respect  thereof
         (except for  Non-Excluded  Taxes covered by subsection 4.16 and changes
         in the rate of net income taxes or franchise  taxes (imposed in lieu of
         net income taxes) of such Lender);

                           (ii)  shall  impose,  modify or hold  applicable  any
         reserve,  special  deposit,  compulsory  loan  or  similar  requirement
         against  assets held by,  deposits or other  liabilities  in or for the
         account of,  advances,  loans or other  extensions of credit by, or any
         other  acquisition  of funds by, any office of such Lender which is not
         otherwise   included  in  the  determination  of  the  Eurodollar  Rate
         hereunder; or

                           (iii)   shall   impose  on  such   Lender  any  other
condition;

and the result of any of the  foregoing  is to increase the cost to such Lender,
by a material  amount of making,  converting  into,  continuing  or  maintaining
Eurodollar  Loans or issuing or  participating in Letters of Credit or to reduce
any amount receivable hereunder in respect thereof,  then, in any such case, the
Borrowers,  jointly and severally, shall promptly pay such Lender within fifteen
(15) days after written request  therefor such  additional  amount or amounts as
will   compensate  such  Lender  for  such  increased  cost  or  reduced  amount
receivable.

                  (b) If any Lender shall have  determined  that the adoption of
or any change in any  Requirement  of Law regarding  capital  adequacy or in the
interpretation or application  thereof,  in each case, after the date hereof, or
compliance  by any  corporation  controlling  such  Lender  with any  request or
directive regarding capital adequacy (whether or not having the force of law, if
compliance  therewith is a customary  banking  practice)  from any  Governmental
Authority  made  subsequent to the date hereof shall have the effect of reducing
the  rate  of  return  on  such  Lender's  or such  corporation's  capital  as a
consequence  of its  obligations  hereunder  or under any  Letter of Credit to a
level below that which such Lender or such  corporation  could have achieved but
for such adoption, change or compliance by the Lender (taking into consideration
such Lender's or such  corporation's  policies with respect to capital adequacy)
by a  material  amount,  then  from time to time,  the  Borrowers,  jointly  and
severally,  shall pay to such Lender such  additional  amount or amounts as will
compensate such Lender within fifteen (15) days after written  request  therefor
for such reduction.

                  (c) If any Lender  becomes  entitled  to claim any  additional
amounts  pursuant to this subsection 4.15, such Lender shall promptly notify the
Borrowers  (with a copy to the  Agent)  of the  event by  reason of which it has
become so entitled.  The  agreements in this  subsection  4.15 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.





                  4.16     Taxes.

                  (a) All payments  made by the Borrowers  under this  Agreement
and any  Notes  shall be made  free and  clear  of,  and  without  deduction  or
withholding  for or on account of, any present or future income,  stamp or other
taxes, levies, imposts,  duties, charges, fees, deductions or withholdings,  now
or  hereafter  imposed,   levied,   collected,   withheld  or  assessed  by  any
Governmental Authority,  excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Agent or any Lender as a result of a
present  or  former  connection  between  the  Agent  or  such  Lender  and  the
jurisdiction of the  Governmental  Authority  imposing such tax or any political
subdivision  or  taxing  authority  thereof  or  therein  (other  than  any such
connection  arising  solely  from the  Lenders  having  executed,  delivered  or
performed  its  obligations  or  received a payment  under,  or  enforced,  this
Agreement or any Note). If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required to
be withheld from any amounts  payable to Agent or any Lender  hereunder or under
any Note,  the amounts so payable to the Agent or such Lender shall be increased
to the extent  necessary to yield to the Agent or such Lender (after  payment of
all Non-Excluded  Taxes) interest or any such other amounts payable hereunder at
the  rates  or  in  the  amounts  specified  in  this  Agreement.  Whenever  any
Non-Excluded  Taxes  are  payable  by any  Borrower,  as  promptly  as  possible
thereafter the Borrowers  shall send to the Agent for its own account or for the
account of such  Lender,  as the case may be, a  certified  copy of an  original
official  receipt  received by the Borrowers  showing  payment  thereof.  If the
Borrowers fail to pay any Non-Excluded  Taxes when due to the appropriate taxing
authority or fail to remit to the Agent the required  receipts or other required
documentary evidence, the Borrowers,  jointly and severally, shall indemnify the
Agent and the Lenders for any  incremental  taxes,  interest or  penalties  that
become  payable by the Agent or any Lender as a result of any such failure.  The
agreements  in this  subsection  4.16  shall  survive  the  termination  of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

                  (b) Each Lender that is not incorporated under the laws of the
United States of America or a state thereof shall:

                           (i)  deliver to the  Borrowers  and the Agent (A) two
         duly completed  copies of the United States  Internal  Revenue  Service
         Form 1001 or 4224,  or successor  applicable  form, as the case may be,
         and (B) an  Internal  Revenue  Service  Form W-8 or W-9,  or  successor
         applicable form, as the case may be;

                           (ii)  deliver  to the  Borrowers  and the  Agent  two
         further copies of any such form or  certification on or before the date
         that any such form or  certification  expires or becomes  obsolete  and
         after the occurrence of any event requiring a change in the most recent
         form previously delivered by it to the Borrowers; and

                           (iii) obtain such  extensions  of time for filing and
         complete such forms or certifications as may reasonably be requested by
         the Borrowers or the Agent;






unless in any such case an event (including,  without limitation,  any change in
treaty,  law or  regulation)  has  occurred  prior to the date on which any such
delivery would  otherwise be required which renders all such forms  inapplicable
or which would prevent such Lender from duly  completing and delivering any such
form with respect to it and such Lender so advises the  Borrowers and the Agent.
Such Lender  shall  certify  (i) in the case of a Form 1001 or 4224,  that it is
entitled  to  receive  payments  under  this  Agreement   without  deduction  or
withholding  of any United States  federal  income taxes and (ii) in the case of
Form W-8 or W-9,  that it is entitled to an exemption  from United States backup
withholding  tax.  Each  Person  that  shall  become a Lender  or a  Participant
pursuant  to  subsection  11.8  shall,  upon the  effectiveness  of the  related
transfer,  be  required  to  provide  all of the forms and  statements  required
pursuant to this  subsection  4.16,  provided  that in the case of a Participant
such  Participant  shall furnish all such required  forms and  statements to the
Lender from which the related participation shall have been purchased.

                  (c) If any  Lender  shall  receive a credit  or refund  from a
taxing  authority  with respect to, and actually  resulting  from,  an amount of
Non-Excluded Taxes actually paid to or on behalf of such Lender by the Borrowers
(a "Tax Credit"),  such Lender shall  promptly  notify the Borrowers of such Tax
Credit.  If such Tax Credit is received by such Lender in the form of cash, such
Lender shall  promptly pay to the  Borrowers the amount so received with respect
to the Tax Credit. If such Tax Credit is not received by such Lender in the form
of cash,  such Lender shall pay the amount of such Tax Credit not later than the
time prescribed by applicable Law for filing the return (including extensions of
time) for such Lenders'  taxable  period which includes the period in which such
Lender  receives  the  economic  benefit of such Tax Credit.  In any event,  the
amount of any Tax Credit  payable by a Lender to the Borrowers  pursuant to this
clause (c) shall not exceed the actual  amount of cash  refunded  to, or credits
received and usable (in accordance with the actual practices then in use by such
Lender) by, such Lender from a taxing  authority.  In determining  the amount of
any Tax Credit,  a Lender may use such  apportionment  and attribution  rules as
such Lender customarily employs in allocating taxes among its various operations
and income sources and such  determination  shall be conclusive  absent manifest
error. The Borrowers, jointly and severally, further agree promptly to return to
a Lender the amount paid to the  Borrowers  with respect to a Tax Credit by such
Lender if such Lender is required to repay,  or is  determined  to be ineligible
for, a Tax Credit for such  amount.  Notwithstanding  anything  to the  contrary
contained  herein,  the Borrowers hereby  acknowledge and agree that (i) neither
the Agent nor any Lender  shall be  obligated  to  provide  the  Borrowers  with
details of the tax position of the Agent or such Lender (as the case may be) and
(ii) the  Borrowers  shall have no right to inspect any records  (including  tax
returns) of the Agent or such Lender (as the case may be).

                  4.17 Indemnity. The Borrowers, jointly and severally, agree to
indemnify each Lender and to hold each Lender  harmless from any loss or expense
which  such  Lender  sustains  or incurs as a  consequence  of (a)  failure by a
Borrower to make a borrowing of,  conversion  into or continuation of Eurodollar
Loans after such Borrower has given a notice  requesting  the same in accordance
with the  provisions  of this  Agreement,  (b) failure by a Borrower to make any
prepayment after such Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment or payment of the
principal  amount of any Eurodollar  Loans on a day which is not the last day of
an Interest Period with respect thereto.




Such  indemnification  may include an amount equal to the excess, if any, of (i)
the amount of interest which would have accrued on the amount so prepaid, or not
so  borrowed,  converted  or  continued,  for the  period  from the date of such
prepayment or of such failure to borrow,  convert or continue to the last day of
such  Interest  Period  (or,  in the case of a failure  to  borrow,  convert  or
continue  the  Interest  Period  that would have  commenced  on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding,  however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) which
would have  accrued to such  Lender on such  amount by  placing  such  amount on
deposit for a comparable  period with leading banks in the interbank  eurodollar
market.  This covenant  shall survive the  termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                  4.18 Change of Lending  Office.  Each Lender agrees that if it
makes any  demand  for  payment  under  subsection  4.15 or  4.16(a),  or if any
adoption or change of the type  described  in  subsection  4.14 shall occur with
respect to it, it will use  reasonable  efforts  (consistent  with its  internal
policy and legal and regulatory  restrictions  and so long as such efforts would
not be  disadvantageous  to it, as determined in its good faith  discretion)  to
designate a different  lending office if the making of such a designation  would
reduce or obviate the need for the Borrowers to make payments  under  subsection
4.15 or  4.16(a),  or would  eliminate  or reduce the effect of any  adoption or
change described in subsection 4.14.

         SECTION 5.  REPRESENTATIONS AND WARRANTIES

                  To induce the Lenders to enter into this Agreement and to make
the  Loans and issue or  participate  in the  Letters  of Credit  the  Borrowers
hereby,  jointly  and  severally,  represent  and  warrant to the Agent and each
Lender that:

                  5.1 Financial Condition. The consolidated balance sheet of ACS
Inc. and its consolidated Subsidiaries as at September 30, 1997, and the related
consolidated  statements  of income and cash flows for the fiscal  year ended on
such  date,  as  reported  on by  Arthur  Andersen,  LLP,  a copy of  which  has
heretofore  been  furnished  to the Agent,  is complete and correct and presents
fairly in all material  respects the  consolidated  financial  condition of such
Borrower and its consolidated Subsidiaries as at such date, and the consolidated
results of their  operations for the fiscal year then ended.  All such financial
statements,  including  the  related  schedules  and  notes  thereto,  have been
prepared in accordance with GAAP.  Neither ACS Inc. nor any of its  consolidated
Subsidiaries  had,  at the date of the most  recent  balance  sheet  referred to
above, any material Guarantee Obligation,  contingent liability or liability for
taxes,  or any  long-term  lease or  unusual  forward or  long-term  commitment,
including,  without  limitation,  any interest rate or foreign  currency swap or
exchange  transaction,  which is not reflected in the foregoing statements or in
the notes  thereto.  Except to the extent  permitted  under this Agreement or as
disclosed  to the Agent prior to the date  hereof,  or as  otherwise  separately
disclosed to the Agent in writing  prior to the date  hereof,  there has been no
sale,  transfer  or other  disposition  by ACS Inc.  or any of its  consolidated
Subsidiaries  of any part of its  business  or property  (including  any capital
stock of any other Person)  material in relation to the  consolidated  financial
condition of ACS Inc. and its consolidated Subsidiaries at September 30,  1997




during the period from September 30, 1997 and including the date hereof.

                  5.2 No Change.  Since  September  30, 1997,  there has been no
development  or event  which has had or could  reasonably  be expected to have a
Material Adverse Effect.

                  5.3 Disclosure. No information, schedule, exhibit or report or
other  document  furnished by each  Borrower or any of its  Subsidiaries  to the
Agent or any Lender in connection  with the negotiation of this Agreement or any
other Loan  Document  (or  pursuant  to the terms  hereof or  thereof),  as such
information,  schedule,  exhibit or report or other  document has been  amended,
supplemented or superseded by any other information, schedule, exhibit or report
or  other  document  later   delivered  to  the  same  parties   receiving  such
information,  schedule,  exhibit  or report  or other  document,  contained  any
material  misstatement  of fact or omitted to state a material  fact or any fact
necessary  to  make  the  statements   contained   therein,   in  light  of  the
circumstances when made, not materially misleading. Any projections so furnished
by each  Borrower or any of its  Subsidiaries  (the  "Projections")  at the time
delivered,  were  based on good  faith  estimates  and  assumptions  made by the
management of such Borrower and, as of the date of their delivery, management of
such  Borrower   believed  that  the  Projections  were  reasonable,   it  being
recognized,  however,  that projections as to future events are not to be viewed
as facts and that the actual results during the period or periods covered by the
Projections  may differ from the projected  results and that the differences may
be material.

                  5.4  Corporate  Existence;  Compliance  with Law.  Each of the
Borrowers and each of its respective Subsidiaries (a) is duly organized, validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
organization, (b) has the corporate power and authority, and the legal right, to
own and operate its property, to lease the property it operates as lessee and to
conduct the business in which it is currently engaged,  (c) is duly qualified as
a foreign  corporation and in good standing under the laws of each  jurisdiction
where its  ownership,  lease or  operation  of  property  or the  conduct of its
business requires such qualification,  except to the extent that all failures to
be so qualified  could not, in the  aggregate,  reasonably be expected to have a
Material  Adverse Effect and (d) is in compliance  with all  Requirements of Law
except to the extent  that all  failures to comply  therewith  could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

                  5.5 Corporate Power,  Authorization,  Enforceable Obligations.
Each Borrower has the corporate  power and  authority,  and the legal right,  to
make,  deliver  and  perform  the Loan  Documents  to which it is a party and to
borrow  hereunder and has taken all necessary  corporate action to authorize the
borrowings on the terms and  conditions  of this  Agreement and any Notes and to
authorize the execution, delivery and performance of the Loan Documents to which
it is a party. No consent or authorization  of, filing with,  notice to or other
act by or in  respect  of, any  Governmental  Authority  or any other  Person is
required in  connection  with the  borrowings  hereunder or with the  execution,
delivery, performance, validity or enforceability of the Loan Documents to which
the  Borrower  is a party  (other  than  filings to perfect  security  interests
granted pursuant to the Security Agreements).  This Agreement has been, and each
other Loan Document to which it




is a party will be, duly executed and delivered on behalf of each Borrower. This
Agreement constitutes,  and each other Loan Document to which it is a party when
executed and delivered will constitute, a legal, valid and binding obligation of
each Borrower  enforceable  against each Borrower in accordance  with its terms,
subject  to  the  effects  of  bankruptcy,  insolvency,  fraudulent  conveyance,
reorganization,  moratorium  and other  similar  laws  relating to or  affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing.

                  5.6 No Legal Bar. The execution,  delivery and  performance of
the Loan Documents to which each Borrower is a party,  the borrowings  hereunder
and the use of the proceeds  thereof will not violate any  Requirement of Law or
Contractual  Obligation of such Borrower or of any of its  Subsidiaries,  except
any violation which would not have a Material Adverse Effect and will not result
in, or require,  the creation or  imposition  of any Lien on any of its or their
respective  properties or revenues  pursuant to any such  Requirement  of Law or
Contractual  Obligation  other  than any Lien  which  would not have a  Material
Adverse Effect.

                  5.7 No Material  Litigation.  Except as otherwise disclosed to
the Agent, as listed on Schedule IX, no litigation,  investigation or proceeding
of or before any  arbitrator  or  Governmental  Authority  is pending or, to the
knowledge of any  Borrower,  threatened by or against any Borrower or any of its
Subsidiaries  or against any of its or their  respective  properties or revenues
(a)  with  respect  to any  of the  Loan  Documents  or any of the  transactions
contemplated  hereby or thereby,  or (b) which could  reasonably  be expected to
have a Material Adverse Effect.

                  5.8  No  Default.   Neither  any   Borrower  nor  any  of  its
Subsidiaries  is in  default  under or with  respect  to any of its  Contractual
Obligations in any respect which could reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

                  5.9  Ownership of Property,  Liens.  Each of the Borrowers and
each of its respective  Subsidiaries has good and marketable title in fee simple
to, or a valid leasehold interest in, all its real property,  and good title to,
or a valid  leasehold  interest  in all its  other  property,  and  none of such
property is subject to any Lien except as permitted by subsection 8.3.

                  5.10 Intellectual Property.  Each of the Borrowers and each of
its respective  Subsidiaries owns, or is licensed to use, all trademarks,  trade
names, copyrights,  technology, know-how and processes necessary for the conduct
of its business as currently  conducted,  except for those for which the failure
to own or license which could not be expected to have a Material  Adverse Effect
(the "Intellectual  Property"). No claim has been asserted and is pending by any
Person  challenging or questioning the use of any such Intellectual  Property or
the  validity or  effectiveness  of any such  Intellectual  Property  which,  if
accurate,  could  reasonably be expected to have a Material  Adverse  Effect nor
does any  Borrower  know of any  valid  basis  for any such  claim.  To the best
knowledge  of  each  Borrower,  the use of such  Intellectual  Property  by each
Borrower  and its  Subsidiaries  does not  infringe on the rights of any Person,
except for such  claims and  infringements  that,  in the  aggregate,  could not
reasonably be expected to have a Material Adverse Effect.


                  5.11 Taxes.  Each of the Borrowers and each of its  respective
Subsidiaries  has filed or caused to be filed all material tax returns which, to
the  knowledge  of such  Borrower,  are  required  to be filed  and has paid all
material taxes shown to be due and payable on said returns or on any assessments
made  against  it or any of its  property  and all  other  taxes,  fees or other
charges  imposed  on it or any of its  property  by any  Governmental  Authority
(other than any the amount or validity of which are currently being contested in
good faith by  appropriate  proceedings  and with  respect to which  reserves in
conformity  with GAAP have been  provided  on the books of the  Borrower  or its
Subsidiaries,  as the case may be and  other  than any  failure  to pay of which
would not have a Material  Adverse  Effect);  no tax Lien has been filed,  other
than Liens  permitted by subsection 8.3, and, to the knowledge of each Borrower,
no claim is being asserted, with respect to any such tax, fee or other charge.

                  5.12 Federal Regulations. No part of the proceeds of any Loans
will be used in any manner which would  violate,  or result in the violation of,
Regulation  D,  Regulation  G or  Regulation  U of the Board of Governors of the
Federal  Reserve  System as now and from time to time  hereafter  in effect.  If
requested by any Lender or the Agent,  each  Borrower  will furnish to the Agent
and each Lender a  statement  to the  foregoing  effect in  conformity  with the
requirements  of FR Form G-3 or FR Form U-1 referred to in said  Regulation G or
Regulation U, as the case may be.

                  5.13 ERISA.  Neither a  Reportable  Event nor an  "accumulated
funding  deficiency"  (within  the meaning of Section 412 of the Code or Section
302 of ERISA) has  occurred  during the  five-year  period  prior to the date on
which this  representation  is made or deemed made with respect to any Plan, and
each Plan has complied in all material  respects with the applicable  provisions
of ERISA and the Code. No  termination  of a Single  Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has  arisen,  during  such  five-year
period.  The present value of all accrued  benefits  under each Single  Employer
Plan  (based on those  assumptions  used to fund such  Plans) did not, as of the
last annual  valuation  date prior to the date on which this  representation  is
made or deemed  made,  exceed the value of the assets of such Plan  allocable to
such accrued benefits.  Neither any Borrower nor any Commonly  Controlled Entity
has had a complete  or  partial  withdrawal  from any  Multiemployer  Plan,  and
neither any Borrower nor any Commonly  Controlled Entity would become subject to
any liability  under ERISA if any such Borrower or any such Commonly  Controlled
Entity  were to  withdraw  completely  from  all  Multiemployer  Plans as of the
valuation date most closely  preceding the date on which this  representation is
made  or  deemed  made.  No such  Multiemployer  Plan  is in  Reorganization  or
Insolvent.  The present value  (determined using actuarial and other assumptions
which are  reasonable  in respect of the  benefits  provided  and the  employees
participating)  of the liability of each  Borrower and each Commonly  Controlled
Entity for post  retirement  benefits to be provided to their current and former
employees  under Plans which are  welfare  benefit  plans (as defined in Section
3(l) of ERISA)  does not,  in the  aggregate,  exceed the assets  under all such
Plans allocable to such benefits by an amount in excess of $100,000.

                  5.14    Investment Company Act; Other Regulations. No Borrower
is  an  "investment  company",  or a  company  "controlled"  by  an  "investment
company", within the meaning of the Investment Company Act of 1940, as amended.



No  Borrower  is subject to  regulation  under any  Federal or State  statute or
regulation  (other than  Regulation  X of the Board of  Governors of the Federal
Reserve System) which limits its ability to incur Indebtedness.

                  5.15  Subsidiaries.  Schedule III hereto sets forth all of the
Subsidiaries  of each  Borrower at the date hereof,  together with the ownership
and jurisdiction of each.

                  5.16     Environmental Matters.

                  (a) The facilities and properties owned, leased or operated by
any Borrower or any of its Subsidiaries (the "Properties") and all operations at
the Properties are in compliance,  and have been in compliance,  in all material
respects, with all applicable  Environmental Laws, and there is no contamination
at or under (or, to the  knowledge  of any  Borrower  about) the  Properties  or
violation  of any  Environmental  Law  with  respect  to the  Properties  or the
business  operated by any Borrower or any of its  Subsidiaries  (the "Business")
except   insofar  as  such   violation  or  failure  to  be  in   compliance  or
contamination, or any aggregation thereof, is not reasonably likely to result in
a payment of a Material Adverse Amount.

                  (b)  Neither  any  Borrower  nor any of its  Subsidiaries  has
received any notice of violation, alleged violation,  non-compliance,  liability
or potential liability regarding  compliance with Environmental Laws with regard
to any of the  Properties or the Business,  nor does any Borrower have knowledge
that any such notice will be received or is being threatened,  except insofar as
such notice or threatened notice, or any aggregation thereof, does not involve a
matter or matters that is or are reasonably likely to result in the payment of a
Material Adverse Amount.

                  (c)   Materials  of   Environmental   Concern  have  not  been
transported  or disposed of from the  Properties in violation of, or in a manner
or to a location  which could  reasonably  be expected to give rise to liability
under, any  Environmental  Law, nor have any Materials of Environmental  Concern
been  generated,  treated,  stored  or  disposed  of at,  on or under any of the
Properties in violation of, or in a manner that could  reasonably be expected to
give rise to liability under, any applicable  Environmental  Law, except insofar
as any  such  violation  or  liability  referred  to in this  paragraph,  or any
aggregation  thereof,  is not  reasonably  likely to result in the  payment of a
Material Adverse Amount.

                  (d) No judicial  proceeding or governmental or  administrative
action is pending or, to the  knowledge of any Borrower,  threatened,  under any
Environmental  Law to which any Borrower,  any of its Subsidiaries is or will be
named as a party with respect to the  Properties or the Business,  nor are there
any consent decrees or other decrees,  consent orders,  administrative orders or
other orders, or other administrative or judicial requirements outstanding under
any  Environmental  Law  which  are  binding  upon  any  Borrower  or any of its
Subsidiaries  with respect to the Properties or the Business,  except insofar as
such proceeding,  action, decree, order or other requirement, or any aggregation
thereof, is not reasonably likely to result in the payment of a Material Adverse
Amount.





                  (e)  There  has  been no  release  or  threat  of  release  of
Materials of Environmental Concern at or from the Properties, or arising from or
related to the operations of any Borrower or any  Subsidiary in connection  with
the Properties or otherwise in connection with the Business,  in violation of or
in amounts or in a manner that could  reasonably  give rise to  liability  under
Environmental  Laws, except insofar as any such violation or liability  referred
to in this paragraph,  or any aggregation  thereof,  is not reasonably likely to
result in a payment of a Material Adverse Amount.

                  5.17     Security Agreements.

                  (a) Each Security  Agreement  constitutes  a legal,  valid and
binding  obligation  of the grantor  party  thereto,  enforceable  against it in
accordance  with  its  terms,   except  as  enforceability  may  be  limited  by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles.

                  (b)  Upon  proper   filing  by  the  Agent  of  the  financing
statements  listed on  Schedule IV hereto  (and,  after the  Closing  Date,  any
additional  filings  required to be made  pursuant to the Loan  Documents),  the
security interests granted pursuant to the Security Agreements will constitute a
valid,  perfected first priority  security interest on the Collateral in which a
security  interest can be perfected  by the filing of financing  statements  (as
described therein)  enforceable as such against all creditors of any grantor and
any Persons  purporting to purchase any such  Collateral from the Loan Party who
is the grantor  with  respect  thereto  (except  purchasers  of Inventory in the
ordinary course of business).

                  5.18 Joinder  Agreements.  Each Joinder Agreement on and after
the date of execution thereof, constitutes a legal, valid and binding obligation
of the Loan Party who is a party thereto,  enforceable  against it in accordance
with  its  terms,  except  as  enforceability  may  be  limited  by  bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general equitable principles.

                  5.19 Solvency. The aggregate value of all of the assets of ACS
Inc. and its Subsidiaries on a consolidated basis, at a fair valuation,  exceeds
the total  liabilities of ACS Inc. and its Subsidiaries on a consolidated  basis
(including contingent,  subordinated,  unmatured and unliquidated  liabilities).
ACS Inc. and its Subsidiaries  have the ability to pay their respective debts as
they mature and do not have  unreasonably  small  capital  with which to conduct
their  respective  businesses.  For purposes of this subsection  5.19, the "fair
valuation"  of such assets is the price at which the assets  would  change hands
between a willing buyer and a willing seller,  both being adequately informed of
the relevant facts, and neither being under any compulsion to buy or to sell.

         SECTION 6.  CONDITIONS PRECEDENT.

                  6.1 Conditions to Initial  Extensions of Credit. The agreement

entry thereof,  or (iv) any Borrower or any Subsidiary  shall take any action in

Plan or any Lien in favor of the PBGC or a Plan shall arise on the assets of any
Borrower or any Commonly Controlled Entity, (iii) a Reportable Event shall occur
with respect to, or proceedings shall commence to have a trustee appointed, or a
trustee shall be appointed,  to administer or to terminate,  any Single Employer
Plan,  which Reportable Event or commencement of proceedings or appointment of a
trustee is, in the reasonable opinion of the Majority Lenders,  likely to result
in the  termination  of such Plan for  purposes  of Title IV of ERISA,  (iv) any
Single Employer Plan shall terminate for purposes of Title IV of ERISA,  (v) any

declaration  is  reasonably  expected to have a Material  Adverse  Effect on the

its Subsidiaries taken as a whole;

then, and in any such event, (i) if such event is an Event of Default  specified
in clause (i) or (ii) of  paragraph  (f) of this  Section 9 with  respect to any
Borrower,  automatically  the Commitments  shall  immediately  terminate and the
Loans  hereunder  (with  accrued  interest  thereon) and all other amounts owing
under  this  Agreement  (including,  without  limitation,  all  amounts  of  L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) shall immediately
become due and  payable,  and (ii) if such event is any other  Event of Default,
either or both of the  following  actions may be taken:  (A) with the consent of
the  Majority  Lenders,  the Agent  may,  or upon the  request  of the  Majority
Lenders,  the Agent shall, by notice to the Borrowers declare the Commitments to
be terminated forthwith,  whereupon the Commitments shall immediately terminate;
and (B) with the  consent of the  Majority  Lenders,  the Agent may, or upon the
request of the Majority  Lenders,  the Agent shall,  by notice to the Borrowers,
declare  the Loans  hereunder  (with  accrued  interest  thereon)  and all other
amounts owing under this Agreement (including,  without limitation,  all amounts
of L/C  Obligations,  whether or not the  beneficiaries  of the then outstanding

due and payable  forthwith,  whereupon the same shall immediately become due and
payable.  Except as expressly  provided  above in this  Section 9,  presentment,

         With respect to all Letters of Credit with respect to which presentment
for honor shall not have occurred at the time of an acceleration pursuant to the
preceding  paragraph,  the  Borrowers  shall  at such  time  deposit  in the L/C
Collateral  Account,  opened by the Lenders  hereunder)  an amount  equal to the
aggregate  then undrawn and  unexpired  amount of such  Letters of Credit.  Each
Borrower  hereby  grants to the Agent,  for the  benefit  of the  holders of the
Secured  Obligations,  the Issuing  Banks and the L/C  Participants,  a security
interest in such cash collateral to secure the Secured Obligations and to secure
all other  obligations  of each Borrower under this Agreement and the other Loan
Documents.  Amounts held in such cash collateral account shall be applied by the
Agent in  accordance  with  the  provisions  of the  Security  Agreements.  Each
Borrower  shall  execute and  deliver to the Agent such  further  documents  and
instruments  as the Agent may request to evidence the creation and perfection of
its security interest in such cash collateral account.

         SECTION 10.  THE AGENT
                  10.1     Appointment. (a) Each Lender hereby irrevocably 
designates and appoints NationsBank, N.A. as the Agent of such Lender under this
Agreement and the other Loan Documents,  and each such  Lender  irrevocably



authorizes the Agent, in such capacity,  to take such action on its behalf under
the  provisions of this  Agreement and the other Loan  Documents and to exercise
such powers and perform such duties as are  expressly  delegated to the Agent by
the terms of this  Agreement  and the other Loan  Documents,  together with such
other powers as are reasonably incidental thereto. Notwithstanding any provision
to the contrary elsewhere in this Agreement, the Agent shall not have any duties
or  responsibilities,  except those expressly set forth herein, or any fiduciary
relationship   with  any   Lender,   and  no   implied   covenants,   functions,
responsibilities,  duties,  obligations or  liabilities  shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.

                  10.2  Delegation  of Duties.  The Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through Agents or
attorneys-in-fact  and shall be  entitled  to advice of counsel  concerning  all
matters  pertaining to such duties.  The Agent shall not be responsible  for the
negligence or misconduct of any Agents or attorneys-in-fact  selected by it with
reasonable care.

                  10.3 Exculpatory Provisions.  Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(i) liable for any  action  lawfully  taken or omitted to be taken by it or such
Person under or in  connection  with this  Agreement or any other Loan  Document
(except for its or such Person's own gross negligence or willful  misconduct) or
(ii)  responsible  in  any  manner  to  any of the  Lenders  for  any  recitals,
statements,  representations  or warranties  made by any Borrower or any officer
thereof  contained  in this  Agreement  or any  other  Loan  Document  or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in  connection  with,  this  Agreement  or any
other Loan  Document  or for the value,  validity,  effectiveness,  genuineness,
enforceability  or  sufficiency  of this Agreement or any other Loan Document or
for any  failure  of any  Borrower  to  perform  its  obligations  hereunder  or
thereunder.  The  Agent  shall  not be under  any  obligation  to any  Lender to
ascertain  or to  inquire  as to the  observance  or  performance  of any of the
agreements  contained  in, or  conditions  of, this  Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrowers.

                  10.4  Reliance by Agent.  The Agent shall be entitled to rely,
and shall be fully  protected in relying,  upon any Note,  writing,  resolution,
notice, consent,  certificate,  affidavit,  letter,  telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed,  sent or made by the proper  Person
or Persons and upon advice and statements of legal counsel  (including,  without
limitation, counsel to any Borrower),  independent accountants and other experts
selected by the Agent.  Without limiting the foregoing or the obligation of each
Borrower  to confirm in writing  any  telephonic  notice  permitted  to be given
hereunder,  the Agent may prior to receipt of written  confirmation  act without
liability  upon the basis of such  telephonic  notice,  believed by the Agent in
good faith to be from a Responsible  Officer of any Borrower or any  Subsidiary.
The Agent may deem and treat the payee of any Note as the owner  thereof for all
purposes unless a written notice of assignment,  negotiation or transfer thereof
shall  have been filed with the Agent.  The Agent  shall be fully  justified  in
failing or refusing to take any action  under this  Agreement  or any other Loan
Document




unless it shall first receive such advice or concurrence of the Majority Lenders
as it deems  appropriate or it shall first be indemnified to its satisfaction by
the Lenders  against any and all  liability and expense which may be incurred by
it by reason of taking or continuing to take any such action. The Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this
Agreement  and the other  Loan  Documents  in  accordance  with a request of the
Majority  Lenders,  and such  request  and any  action  taken or  failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of
the Loans.

                  10.5 Notice of Default.  The Agent shall not be deemed to have
knowledge  or  notice  of the  occurrence  of any  Default  or Event of  Default
hereunder  unless  the Agent has  received  notice  from a Lender or a  Borrower
referring  to this  Agreement,  describing  such Default or Event of Default and
stating that such notice is a "notice of  default".  In the event that the Agent
receives such a notice, the Agent shall give notice thereof to the Lenders.  The
Agent shall take such action with respect to such Default or Event of Default as
shall be reasonably  directed by the Majority Lenders;  provided that unless and
until the Agent shall have  received such  directions,  the Agent may (but shall
not be obligated to) take such action, or refrain from taking such action,  with
respect to such  Default or Event of Default as it shall deem  advisable  in the
best interests of the Lenders.

                  10.6  Non-Reliance  on Agent and Other  Lenders.  Each  Lender
expressly  acknowledges  that  neither  the  Agent  nor  any  of  its  officers,
directors,  employees,  Agents,  attorneys-in-fact  or  Affiliates  has made any
representations  or  warranties  to it and that no act by the Agent  hereinafter
taken,  including any review of the affairs of any Borrower,  shall be deemed to
constitute  any  representation  or warranty  by the Agent to any  Lender.  Each
Lender  represents to the Agent that it has,  independently and without reliance
upon the Agent or any other Lender,  and based on such documents and information
as it has deemed  appropriate,  made its own appraisal of and investigation into
the  business,   operations,   property,   financial  and  other  condition  and
creditworthiness  of each  Borrower  and made its own decision to make its Loans
hereunder and enter into this  Agreement.  Each Lender also  represents  that it
will, independently and without reliance upon the Agent or any other Lender, and
based on such  documents and  information  as it shall deem  appropriate  at the
time,  continue to make its own credit  analysis,  appraisals  and  decisions in
taking or not taking action under this  Agreement and the other Loan  Documents,
and to make such  investigation as it deems necessary to inform itself as to the
business,   operations,    property,   financial   and   other   condition   and
creditworthiness  of each  Borrower.  Except  for  notices,  reports  and  other
documents  expressly  required  to be  furnished  to the  Lenders  by the  Agent
hereunder,  the Agent shall not have any duty or  responsibility  to provide any
Lender with any credit or other information concerning the business, operations,
property,  condition (financial or otherwise),  prospects or creditworthiness of
each  Borrower  which  may come into the  possession  of the Agent or any of its
officers, directors, employees, Agents, attorneys-in-fact or Affiliates.

                  10.7 Indemnification. The Lenders agree to indemnify the Agent
in its  capacity  as such (to the extent not  reimbursed  by the  Borrowers  and
without limiting the obligation of the Borrowers to do so), ratably according to
their  respective  Commitment  Percentages  in  effect  on  the  date  on  which
indemnification is sought (such Commitment Percentage to be determined as if




there are not  Defaulting  Lenders),  from and against any and all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses  or  disbursements  of any  kind  whatsoever  which  may  at  any  time
(including,  without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted  against the Agent in any way relating to
or  arising  out of,  the  Commitments,  this  Agreement,  any of the other Loan
Documents or any documents  contemplated  by or referred to herein or therein or
the transactions  contemplated  hereby or thereby or any action taken or omitted
by the Agent under or in connection with any of the foregoing;  provided that no
Lender  shall be liable  for the  payment of any  portion  of such  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements  resulting solely from the Agent's gross negligence or
willful misconduct. To the extent that any Lender would be required to indemnify
the  Agent  pursuant  to this  subsection  10.7  but for the  fact  that it is a
Defaulting  Lender,  such Defaulting Lender shall not be entitled to receive any
portion of any payment or other  distribution  hereunder until each other Lender
shall have been reimbursed for the excess,  if any, of the aggregate amount paid
by such Lender under this  subsection  10.7 over the aggregate  amount that such
Lender  would  have  been  obligated  to pay had such  first  Lender  not been a
Defaulting  Lender.  The  agreements in this  subsection  10.7 shall survive the
payment of the Loans and all other amounts payable hereunder.

                  10.8 Agent in its Individual  Capacity.  The Agent and each of
its respective  Affiliates may make loans to, accept deposits from and generally
engage in any kind of  business  with any  Borrower as though the Agent were not
the Agent  hereunder  and under the other Loan  Documents.  With  respect to its
Loans made or renewed  by it and any Note  issued to it and with  respect to any
Letter of Credit issued or  participated in by it, the Agent shall have the same
rights  and powers  under this  Agreement  and the other Loan  Documents  as any
Lender and may exercise the same as though it were not the Agent,  and the terms
"Lender" and  "Lenders"  shall  include the Agent in its  respective  individual
capacity.

                  10.9 Successor  Agent.  The Agent may resign as Agent upon ten
(10) days' notice to the Lenders and the Borrowers. If the Agent shall resign as
Agent  under this  Agreement  and the other Loan  Documents,  then the  Majority
Lenders shall appoint from among the Lenders a successor  Agent for the Lenders,
which  successor  Agent  (provided  that it  shall  have  been  approved  by the
Borrowers),  shall  succeed  to the  rights,  powers  and  duties  of the  Agent
hereunder.  Effective upon such appointment and approval, the term "Agent" shall
mean such successor Agent,  and the former Agent's rights,  powers and duties as
Agent shall be terminated,  without any other or further act or deed on the part
of such former  Agent or any of the parties to this  Agreement or any holders of
the Loans.  After any retiring  Agent's  resignation as Agent, the provisions of
this Section 10 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was  Agent  under  this  Agreement  and the  other  Loan
Documents.

         SECTION 11.  MISCELLANEOUS
                  11.1  Amendments  and Waivers.  Neither this Agreement nor any
other  Loan  Document,  nor  any  terms  hereof  or  thereof,  may  be  amended,
supplemented  or  modified  except in  accordance  with the  provisions  of this
subsection 11.1. The Majority Lenders may, or, with the written




consent of the  Majority  Lenders,  the Agent may,  from time to time,  with the
consent of the Borrowers (a) enter into with the Borrowers  written  amendments,
supplements  or  modifications  hereto and to the other Loan  Documents  for the
purpose of adding any  provisions to this  Agreement or the other Loan Documents
or  changing  in any  manner  the  rights  of the  Lenders  or of the  Borrowers
hereunder  or  thereunder  or (b)  waive,  on such terms and  conditions  as the
Majority  Lenders  or the  Agent,  as the  case  may  be,  may  specify  in such
instrument,  any of the  requirements  of  this  Agreement  or  the  other  Loan
Documents  or any  Default or Event of Default and its  consequences;  provided,
however,  that no such waiver and no such amendment,  supplement or modification
shall:

                           (i) reduce the amount or extend the scheduled date of
         maturity  of any Loan or of any  installment  thereof,  or  reduce  the
         stated  rate of any  interest or fee  payable  hereunder  or extend the
         scheduled date of any payment  thereof or increase the amount or extend
         the expiration  date of any Lender's  Commitment,  in each case without
         the consent of each Non-Defaulting Lender directly affected thereby;

                           (ii)  amend,  modify or waive any  provision  of this
         subsection 11.1 or reduce the percentage specified in the definition of
         Majority  Lenders,  in each case without the written consent of all the
         Non-Defaulting Lenders;

                           (iii)  consent to the  assignment  or transfer by any
         Borrower of any of its rights and obligations  under this Agreement and
         the other Loan  Documents,  in each case without the written consent of
         all the Non-Defaulting Lenders;

                           (iv)  release of any of the  material  collateral  or
         material  guarantee  obligations  provided for in a Security  Document,
         without the written  consent of the  Non-Defaulting  Lenders  except in
         connection with permitted dispositions of Collateral;

                           (v) amend, modify or waive any provision of Section 3
         without the written  consent of each  Issuing  Bank  directly  affected
         thereby (provided that, such Issuing Bank is a Non-Defaulting  Lender);
         or

                           (vi) amend,  modify or waive any provision of Section
11 without the written consent of the
then Agent.

Any such waiver and any such amendment,  supplement or modification  shall apply
equally  to each of the  Lenders  (including  Defaulting  Lenders)  and shall be
binding upon each Borrower,  the Lenders  (including  Defaulting  Lenders),  the
Agent and all  future  holders  of the  Loans.  In the case of any  waiver,  the
Borrowers,  the Lenders  (including  Defaulting  Lenders) and the Agent shall be
restored to their former positions and rights hereunder and under the other Loan
Documents,  and any  Default  or Event of Default  waived  shall be deemed to be
cured and not continuing; no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon.

                  11.2  Releases of Collateral Security. Notwithstanding 
anything to the  contrary  contained  herein or in any Security  Document,  upon
request of the Borrowers, the Agent shall (without  any notice to or vote



or consent of any Lender) take any action which has the effect of releasing  any
collateral  security  and/or  guarantee  obligations  provided  for in any  Loan
Document to the extent  necessary to permit the consummation of any Net Proceeds
Event or any asset  dispositions  permitted by  subsection  8.6;  provided  that
(unless the Majority  Lenders shall  otherwise  consent) the Net Proceeds of any
Net Proceeds Event are applied in the manner  contemplated by subsection 4.5 (if
so required). 

u                11.3 Notices. Unless otherwise expressly provided herein, all
notices,  requests and demands to or upon the  respective  parties  hereto to be

and no delay in  exercising  on the part of the Agent or any Lender,  any right,
remedy,  power or privilege  hereunder or under the other Loan  Documents  shall

exercise thereof or the exercise of any other right, remedy, power or privilege.
The rights,  remedies,  powers and privileges herein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

                  11.5  Survival  of   Representations   and   Warranties.   All
representations  and warranties made hereunder,  in the other Loan Documents and
in any  document,  certificate  or  statement  delivered  pursuant  hereto or in

of this Agreement pursuant to subsection 11.7.

                  11.6 Payment of Expenses and Taxes. The Borrowers, jointly and
severally,  agree (a) to pay or  reimburse  the Agent for all of its  reasonable
out-of-pocket  costs and expenses  incurred in connection with the  development,
preparation and execution of any amendment,  supplement or modification to, this
Agreement  and the other Loan  Documents  and any other  documents  prepared  in
connection herewith or therewith, and the consummation and administration of the
transactions contemplated hereby and thereby, including, without limitation, the
reasonable  fees  and  disbursements  of  counsel  to the  Agent,  (b) to pay or
reimburse  each Lender and the Agent for all its costs and expenses  incurred in
connection with the enforcement or with respect to the Agent,  the  preservation
of any rights under this Agreement, the other Loan Documents and any




such other documents,  including,  without  limitation,  the reasonable fees and
disbursements of counsel to each Lender and of counsel to the Agent, (c) to pay,
indemnify,  and hold  each  Lender  and the  Agent  harmless  from,  any and all
recording  and  filing  fees and any and all  liabilities  with  respect  to, or
resulting from any delay in paying, stamp, excise and other taxes, if any, which
may be payable or determined to be payable in connection  with the execution and
delivery  of,  or  consummation  or  administration  of any of the  transactions
contemplated by, or any amendment,  supplement or modification of, or any waiver
or consent under or in respect of, this Agreement,  the other Loan Documents and
any such other documents,  and (d) to pay,  indemnify,  and hold each Lender and
the Agent harmless from and against any and all other liabilities,  obligations,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements  of any kind or nature  whatsoever  with respect to any Letters of
Credit or the execution, delivery,  enforcement,  performance and administration
of this  Agreement,  the other Loan  Documents or the use of the proceeds of the
Loans and any such other documents,  including,  without limitation,  any of the
foregoing  relating to the violation of,  noncompliance with or liability under,
any  Environmental  Law  applicable  to  the  operations  of any  Borrower,  any
Subsidiary  or any of the  Properties  (all the  foregoing  in this  clause (d),
collectively, the "indemnified liabilities"),  provided that the Borrowers shall
have no  obligation  hereunder  to the  Agent  or any  Lender  with  respect  to
indemnified  liabilities  to the extent arising from the gross  negligence,  bad
faith or willful  misconduct of the Agent or such Lender. The agreements in this
subsection  11.6  shall  survive  repayment  of the Loans and all other  amounts
payable hereunder.

                  11.7  Termination.  This  Agreement  shall  terminate upon the
termination  of all  Commitments  and the  irrevocable  repayment in full of the
aggregate  outstanding  principal amount of the Loans, accrued interest thereon,
and all fees and expenses  and other  amounts due and payable at such time under
any of the Loan  Documents;  provided  that all  indemnities  set  forth  herein
including,  without limitation,  in subsections 4.14, 4.15, 4.16, 4.17, 10.7 and
11.6 shall survive such termination.

                  11.8   Successors and Assigns; Participations and Assignments.

                  (a) This  Agreement  shall be  binding  upon and  inure to the
benefit of the Borrowers, the Lenders, the Agent and their respective successors
and assigns, except that no Borrower may assign or transfer any of its rights or
obligations  under this  Agreement  without  the prior  written  consent of each
Lender.

                  (b) Any Lender may, in the ordinary  course of its  commercial
banking  business and in accordance with applicable law, at any time sell to one
or more banks or other  financial  institutions  ("Participants")  participating
interests in any Loan owing to such Lender, any Commitment of such Lender or any
other interest of such Lender  hereunder and under the other Loan Documents.  In
the  event  of any  such  sale by a  Lender  of a  participating  interest  to a
Participant,  such  Lender's  obligations  under  this  Agreement  shall  remain
unchanged,  such Lender  shall remain  solely  responsible  for the  performance
thereof,  such Lender  shall remain the holder of any such Loan for all purposes
under this  Agreement  and the other Loan  Documents,  and the Borrowers and the
Agent shall continue to deal solely and directly with such Lender in connection




with such Lender's  rights and  obligations  under this  Agreement and the other
Loan  Documents.  No  Lender  shall  be  entitled  to  create  in  favor  of any
Participant, in the participation agreement pursuant to which such Participant's
participating  interest  shall be  created or  otherwise,  any right to vote on,
consent to or approve any matter  relating to this  Agreement  or any other Loan
Document  except for those  specified  in clauses (i) and (ii) of the proviso to
subsection  11.1.  The Borrowers  agree that if amounts  outstanding  under this
Agreement  are due or unpaid,  or shall have been  declared or shall have become
due and payable upon the  occurrence  of an Event of Default,  each  Participant
shall, to the maximum extent  permitted by applicable law, be deemed to have the
right of setoff in respect of its participating  interest in amounts owing under
this Agreement to the same extent as if the amount of its participating interest
were owing  directly to it as a Lender under this  Agreement,  provided that, in
purchasing such participating interest, such Participant shall be deemed to have
agreed to share with the Lenders the  proceeds  thereof as fully as if it were a
Lender  hereunder.  The  Borrowers  also  agree that each  Participant  shall be
entitled to the benefits of subsections  4.14,  4.15, 4.16 and 4.17 with respect
to its  participation in the Commitments and the Loans  outstanding from time to
time as if it was a Lender;  provided that, in the case of subsection 4.16, such
Participant  shall have complied with the  requirements  of said  subsection and
provided,  further, that no Participant shall be entitled to receive any greater
amount pursuant to any such subsection than the Lenders would have been entitled
to receive in respect  of the amount of the  participation  transferred  by such
Lender to such Participant had no such transfer occurred.

                  (c) Any Lender may, in the ordinary  course of its  commercial
banking  business and in accordance  with  applicable  law, at any time and from
time to time assign to any Lender or any affiliate  thereof or, with the consent
of the  Borrowers  and the Agent  (which in each case shall not be  unreasonably
withheld), to an additional bank or financial institution (an "Assignee") all or
any part of its rights and  obligations  under this Agreement and the other Loan
Documents pursuant to an Assignment and Acceptance, substantially in the form of
Exhibit G, executed by such Assignee, such assigning Lender (and, in the case of
an Assignee that is not then a Lender or an affiliate thereof,  by the Borrowers
and the Agent) and  delivered  to the Agent for its  acceptance  and  recording,
provided  that,  in the case of any such  assignment  to an  additional  bank or
financial  institution,  (x)  the  aggregate  amount  of the  Commitments  being
assigned are not less than $1,000,000 (or such lesser amount as may be agreed to
by the Borrowers  and the Agent) and (y) if such  assignment is of less than all
of the rights and obligations of the assigning  Lender,  the aggregate amount of
the  Commitment  remaining  with the  assigning  Lender  are each not less  than
$1,000,000  (or such lesser  amount as may be agreed to by the Borrowers and the
Agent).  Notwithstanding  the  foregoing,  so  long  as no  event  described  in
subsection  9(f) shall have  occurred and be  continuing,  unless the  Borrowers
shall have otherwise consented,  NationsBank, N.A. shall at all times retain (i)
not less than thirty percent (30%) of the sum of the  Commitments of the Lenders
and (ii) a Commitment Percentage of each Facility greater than that of any other
single Lender hereunder. Upon such execution, delivery, acceptance and recording
(and the payment of the  registration and processing fee described in clause (e)
below), from and after the effective date determined pursuant to such Assignment
and Acceptance,  (x) 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 Lender hereunder with a Commitment as set forth therein,




and (y) the assigning  Lender  thereunder  shall, to the extent provided in such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance  covering all or the remaining
portion of the  Lenders'  rights and  obligations  under  this  Agreement,  such
assigning  Lender  shall  cease  to  be a  party  hereto).  Notwithstanding  any
provision of this paragraph (c) of this subsection, the consent of the Borrowers
shall not be required  for any  assignment  which occurs at any time when any of
the events described in subsection 9(f) shall have occurred and be continuing.

                  (d) The Agent,  on behalf of the Borrowers,  shall maintain at
the  address  of the  Agent  referred  to in  subsection  11.3 a  copy  of  each
Assignment and Acceptance  delivered to it and a register (the  "Register")  for
the  recordation  of the names and addresses of the Lenders and the  Commitments
of, and principal  amounts of the Loans owing to, each Lender from time to time.
The entries in the Register shall, to the extent permitted by applicable law, be
prima facie evidence of the information  contained  therein,  and the Borrowers,
the Agent and the Lenders may (and, in the case of any Loan or other  obligation
hereunder  not  evidenced  by a Note,  shall)  treat each  Person  whose name is
recorded in the Register as the owner of a Loan or other obligation hereunder as
the  owner  thereof  for all  purposes  of this  Agreement  and the  other  Loan
Documents,  notwithstanding  any notice to the contrary.  Any  assignment of any
Loan or other  obligation  hereunder  not evidenced by a Note shall be effective
only upon  appropriate  entries with respect thereto being made in the Register.
The Register  shall be available for inspection by any Borrower or any Lender at
any reasonable time and from time to time upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance  executed
by an assigning  Lender and an Assignee (and, in the case of an Assignee that is
not then a Lender or an  affiliate  thereof,  by the  Borrowers  and the Agent),
together  with  payment to the Agent of a  registration  and  processing  fee of
$2,500 by such Assignee, the Agent shall (i) promptly accept such Assignment and
Acceptance and (ii) on the effective date determined pursuant thereto record the
information contained therein in the Register and give notice of such acceptance
and  recordation  to the Lenders and the  Borrowers;  provided  that no such fee
shall be payable with respect to any assignment  from an assigning  Lender to an
affiliate thereof.

                  (f) The  Borrowers  authorize  each  Lender to disclose to any
Participant or Assignee  (each, a "Transferee")  and any prospective  Transferee
any and all financial  information  in such Lenders'  possession  concerning any
Borrower or any Affiliate of a Borrower  which has been delivered to such Lender
by or on behalf of such  Borrower  pursuant to this  Agreement or which has been
delivered to such Lender by or on behalf of any such Borrower in connection with
such Lenders' credit evaluation of any such Borrower and its Affiliates prior to
becoming a party to this Agreement.

                  (g) For  avoidance  of doubt,  the  parties to this  Agreement
acknowledge  that the provisions of this subsection 11.8 concerning  assignments
of Loans and Notes relate only to absolute  assignments and that such provisions
do not prohibit assignments creating security interests,




including,  without limitation, any pledge or assignment by a Lender of any Loan
or Note to any Federal Reserve Bank in accordance with applicable law.

                  11.9     Adjustments; Set-off.

                  (a) If any  Lender (a  "Benefited  Lender")  at any time shall
receive any payment of all or part of its Loans or the Reimbursement Obligations
owing to it, or interest  thereon,  or receive any collateral in respect thereof
(whether  voluntarily  or  involuntarily,  by  set-off,  pursuant  to  events or
proceedings of the nature  referred to in subsection  9(f), or otherwise),  in a
greater proportion than any such payment to or collateral  received by any other
Lender,  if any, in respect of such other  Lenders'  Loans or the  Reimbursement
Obligations  owing  to it (as the  case  may  be),  or  interest  thereon,  such
benefited  Lender shall purchase for cash from the other Lenders such portion of
each such other Lenders' Loans or the Reimbursement  Obligations owing to it (as
the case may be), or shall  provide such other  Lenders with the benefits of any
such collateral,  or the proceeds  thereof,  as shall be necessary to cause such
benefited  Lender to share the excess payment or benefits of such  collateral or
proceeds ratably with each of the Lenders, and if after taking into account such
sharing the benefited  Lender  continues to have access to addition  funds of or
collateral  granted by any Borrower for application on account of its debt, then
the benefited  Lender shall use such funds or collateral to reduce  Indebtedness
of any such Borrower held by it and share such payments and the benefits of such
collateral with the other Lenders; provided, however, that if all or any portion
of such excess  payment or benefits is thereafter  recovered from such benefited
Lender,  such purchase  shall be rescinded,  and the purchase price and benefits
returned, to the extent of such recovery,  but without interest.  The Borrowers,
jointly and severally, agree that each Lender so purchasing a portion of another
Lenders' Loans or  Reimbursement  Obligations may exercise all rights of payment
(including,  without limitation, rights of set-off) with respect to such portion
as fully as if such Lender were the direct holder of such portion.

                  (b) In  addition  to any rights and  remedies  of the  Lenders
provided by law,  each Lender shall have the right,  without prior notice to any
Borrower,  any such notice being expressly waived by each Borrower to the extent
permitted by  applicable  law,  upon any amount  becoming due and payable by any
Borrower  hereunder  (whether  at  the  stated  maturity,   by  acceleration  or
otherwise) to set-off and  appropriate and apply against such amount any and all
deposits  (general or special,  time or demand,  provisional  or final),  in any
currency,  and any other credits,  indebtedness or claims,  in any currency,  in
each case  whether  direct or  indirect,  absolute  or  contingent,  matured  or
unmatured, at any time held or owing by such Lender or any branch, agency or (to
the extent permitted by applicable law) banking  affiliate thereof to or for the
credit or the account of any Borrower. Each Lender agrees promptly to notify the
Borrowers  and the Agent or any Lender  after any such  set-off and  application
made by such  Lender,  provided  that the failure to give such notice  shall not
affect the validity of the set-off and application.

                  11.10 Joint and Several  Liability.  WHETHER OR NOT  EXPRESSLY
STATED HEREIN OR IN ANY OTHER LOAN  DOCUMENT,  ALL  OBLIGATIONS OF THE BORROWERS
(OR OF ANY BORROWER)  HEREUNDER  AND UNDER EACH OTHER LOAN DOCUMENT  (WHETHER IN
CONNECTION WITH LOANS, LETTERS OF CREDIT OR




OTHER OBLIGATIONS) ARE JOINT AND SEVERAL OBLIGATIONS OF ALL BORROWERS.

                  11.11 Maximum  Amount of Joint and Several  Liability.  To the
extent that  applicable Law otherwise  would render the full amount of the joint
and several  obligations of any  Subsidiary of ACS Inc.  hereunder and under the
other Loan Documents  invalid or unenforceable,  such  Subsidiary's  obligations
hereunder and under the Loan  Documents  shall be limited to the maximum  amount
which does not result in such invalidity or unenforceability, provided, however,
that each  Borrower's  obligations  hereunder and under the other Loan Documents
shall be  presumptively  valid  and  enforceable  to  their  fullest  extent  in
accordance with the terms hereof or thereof,  as if this  subsection  11.11 were
not a part of this Agreement.

                  11.12  Counterparts.  This Agreement may be executed by one or
more of the parties to this  Agreement  on any number of  separate  counterparts
(including  by  facsimile  transmission),  and  all of said  counterparts  taken
together shall be deemed to constitute one and the same instrument. A set of the
copies of this Agreement signed by all the parties shall be lodged with ACS Inc.
and the Agent.

                  11.13  Severability.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

                  11.14 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrowers, the Agent and the Lenders with respect
to  the  subject  matter  hereof,  and  there  are  no  promises,  undertakings,
representations  or  warranties  by the Agent or any Lender  relative to subject
matter hereof not expressly set forth or referred to herein or in the other Loan
Documents.  For the avoidance of doubt, the terms and conditions of that certain
commitment  letter  dated as of  January  28,  1998 from  NationsBank,  N.A.  to
Advanced  Communication  Systems,  Inc. shall be deemed to have been  superceded
