           (b) Disbursement of Revolving Credit Loans Denominated in Dollars.
Not later than 2:00 p.m. (Charlotte time) on the proposed borrowing date for any
Loan denominated in Dollars, each Lender will make available to the
Administrative Agent, for the account of the Borrower, at the office of the
Administrative Agent in Dollars in funds immediately available to the
Administrative Agent, such Lender's Commitment Percentage of the requested Loan
to be made on such borrowing date. The Borrower hereby irrevocably authorizes
the Administrative Agent to disburse the proceeds of each borrowing requested
pursuant to this Section 2.2 in immediately available funds by crediting or
wiring such proceeds to the deposit account of the Borrower identified in the
most recent notice substantially in the form of Exhibit C hereto (a "Notice of
Account Designation") delivered by the Borrower to the Administrative Agent or
may be otherwise agreed upon by the Borrower and the Administrative Agent from
time to time. Subject to Section 4.7, the Administrative Agent shall not be
obligated to disburse the portion of the proceeds of any Loan requested pursuant
to this Section 2.2 to the extent that any Lender has not made available to the
Administrative Agent its Commitment Percentage of such Loan.

           (c) Disbursement of Alternative Currency Loans. Not later than 11:00
a.m. (the time of the Administrative Agent's Correspondent) on or before the
proposed borrowing date for any Alternative Currency Loan, each Lender will make
available to the Administrative Agent for the account of the Borrower at the
office of the Administrative Agent's Correspondent, in the requested Alternative
Currency in funds immediately available to the Administrative Agent, such
Lender's Commitment Percentage of the Alternative Currency Amount of such
requested borrowing. The Borrower hereby irrevocably authorizes the
Administrative Agent to disburse the proceeds of each borrowing requested
pursuant to this Section 2.2 in immediately available funds by crediting or
wiring such proceeds to the deposit account of the Borrower identified in the
most recent Notice of Account Designation delivered by the Borrower to the
Administrative Agent or may be otherwise agreed upon by the Borrower and the
Administrative Agent from time to time. Subject to Section 4.7, the
Administrative Agent shall not be obligated to disburse the portion of the
proceeds of any Loan requested pursuant to this Section 2.2 to the extent that
any Lender has not made available to the Administrative Agent its Commitment
Percentage of such Loan.

           SECTION 2.3 Repayment of Loans.

           (a) Repayment on Termination Date. The Borrower shall repay the
outstanding principal amount of all Loans in full on the Revolving Credit
Termination Date.

           (b) Mandatory Repayment of Excess Loans.

                      (i) Aggregate Commitment. If at any time (as determined by
the Administrative Agent under Section 2.3(b)(iv), and for any reason, the
aggregate principal Dollar Amount of all outstanding Loans exceeds one hundred
and five percent (105%) of the Aggregate Commitment less all outstanding L/C
Obligations, the Borrower shall (A) first, if (and to the extent) necessary to
eliminate such excess, immediately repay outstanding Base Rate Loans by the
Dollar Amount of such excess (and/or reduce any pending request for a Base Rate
Loan on such day by the Dollar Amount of such excess), (B) second, if (and to
the extent) necessary to eliminate such 



                                       16
<PAGE>   23

excess, immediately repay LIBOR Market Rate Loans (and/or reduce any pending
requests for a borrowing) and (C) third, if (and to the extent) necessary to
eliminate such excess, immediately repay LIBOR Rate Loans (and/or reduce any
pending requests for a borrowing or continuation or conversion of such Loans
submitted in respect of such Loans on such day) by the Dollar Amount of any
remaining excess.

                      (ii) Excess Alternative Currency Loans. If at any time and
for any reason the outstanding principal amount of all outstanding Alternative
Currency Loans exceeds the lesser of (A) the Aggregate Commitment less the sum
of the outstanding principal amount of all Loans denominated in Dollars less the
sum of the outstanding principal Dollar Amount of all L/C Obligations and (B)
the Alternative Currency Commitment, such excess shall be immediately repaid, in
the currency in which such Alternative Currency Loan or Alternative Currency
Loans were initially funded, by the Borrower to the Administrative Agent for the
account of the Lenders.

                      (iii) Excess L/C Obligations. If at any time and for any
reason the aggregate outstanding principal amount of the L/C Obligations exceeds
the lesser of (1) the Aggregate Commitment less the sum of the Dollar Amount of
the aggregate principal amount of all outstanding Loans and (2) the L/C
Commitment, then the Borrower shall deposit an amount equal to such excess with
the Administrative Agent to be held as cash collateral in accordance with
Section 11.2(b); provided that any such cash collateral shall be released
promptly to the Borrower at any time that the aggregate outstanding principal
amount of the L/C Obligations no longer exceeds the thresholds described in
clauses (1) and (2) of this subsection (iii).

                      (iv) Compliance and Payments. The Borrower's compliance
with this Section 2.3(b) shall be tested from time to time by the Administrative
Agent at its sole discretion, but in any event on each day an interest payment
is due under Section 4.1(f). Each such repayment pursuant to this Section 2.3(b)
shall be accompanied by any amount required to be paid pursuant to Section 4.11
hereof.

           (c) Optional Repayments. The Borrower may at any time and from time
to time repay the Loans, in whole or in part, upon at least four (4) Business
Days' irrevocable notice to the Administrative Agent with respect to LIBOR Rate
Loans denominated in an Alternative Currency, upon at least two (2) Business
Days' irrevocable notice to the Administrative Agent with respect to Base Rate
Loans and LIBOR Market Rate Loans denominated in an Alternative Currency and
same Business Day irrevocable notice with respect to Base Rate Loans, LIBOR
Market Rate Loans and LIBOR Rate Loans denominated in Dollars, in the form
attached hereto as Exhibit D (a "Notice of Prepayment") specifying the date and
amount of repayment and whether the repayment is of Base Rate Loans, LIBOR
Market Rate Loans or LIBOR Rate Loans denominated in an Alternative Currency or
denominated in Dollars, or a combination thereof, and, if of a combination
thereof, the amount allocable to each. Upon receipt of such notice, the
Administrative Agent shall promptly notify each Lender. If any such notice is
given, the amount specified in such notice shall be due and payable on the date
set forth in such notice. Partial repayments shall be in an aggregate amount of
$100,000 or a whole multiple of $50,000 in excess thereof with respect to Base
Rate Loans and LIBOR Market Rate Loans and $3,000,000 or a whole multiple of
$1,000,000 in excess thereof 



                                       17
<PAGE>   24

with respect to LIBOR Rate Loans. Each such repayment shall be accompanied by
any amount required to be paid pursuant to Section 4.11 hereof.

           (d) Limitation on Repayment of LIBOR Rate Loans. The Borrower may not
repay any LIBOR Rate Loan on any day other than on the last day of the Interest
Period applicable thereto unless such repayment is accompanied by any amount
required to be paid pursuant to Section 4.11 hereof.

           SECTION 2.4 Revolving Credit Loans. Each Lender's Loans and the
obligation of the Borrower to repay such Loans shall be evidenced by a separate
Note executed by the Borrower payable to the order of such Lender representing
the Borrower's obligation to pay such Lender's Commitment or, if less, the
aggregate unpaid principal amount of all Loans made and to be made by such
Lender to the Borrower hereunder, plus interest and all other fees, charges and
other amounts due thereon. Each Note shall be dated the date hereof and shall
bear interest on the unpaid principal amount thereof at the applicable interest
rate per annum specified in Section 4.1.

           SECTION 2.5 Permanent Reduction of the Aggregate Commitment.

           (a) Voluntary Reduction. The Borrower shall have the right at any
time and from time to time, upon at least five (5) Business Days prior written
notice to the Administrative Agent, to permanently reduce, without premium or
penalty, (i) the entire Aggregate Commitment at any time or (ii) portions of the
Aggregate Commitment, from time to time, in an aggregate principal amount not
less than $3,000,000 or any whole multiple of $1,000,000 in excess thereof. To
the extent that the Aggregate Commitment is reduced to an amount below the
Alternative Currency Commitment, there shall be a corresponding permanent
reduction of the Alternative Currency Commitment, to the amount of the Aggregate
Commitment as so reduced. The amount of each partial permanent reduction shall
be applied pro rata to reduce the remaining mandatory reduction amounts required
under Section 2.5(b).

           (b) Each permanent reduction permitted or required pursuant to this
Section 2.5 shall be accompanied by a payment of principal sufficient to reduce
the aggregate outstanding Extensions of Credit of the Lenders after such
reduction to the Aggregate Commitment as so reduced and if the Aggregate
Commitment as so reduced is less than the aggregate amount of all outstanding
Letters of Credit, the Borrower shall be required to deposit in a cash
collateral account opened by the Administrative Agent an amount equal to the
aggregate then undrawn and unexpired amount of such Letters of Credit (which
cash collateral the Administrative Agent shall promptly release to the Borrower
of such times as the Aggregate Commitment no longer exceeds the aggregate amount
of all outstanding Letters of Credit). Any reduction of the Aggregate Commitment
to zero shall be accompanied by payment of all outstanding Obligations (and
furnishing of cash collateral satisfactory to the Administrative Agent for all
L/C Obligations) and shall result in the termination of the Commitments and
Credit Facility. Such cash collateral shall be applied, subject to the foregoing
provisions of this Section 2.5(b), in accordance with Section 11.2(b). If the
reduction of 



                                       18
<PAGE>   25

the Aggregate Commitment requires the repayment of any LIBOR Rate Loan, such
repayment shall be accompanied by any amount required to be paid pursuant to
Section 4.11 hereof.

           SECTION 2.6 Termination of Credit Facility. The Credit Facility shall
terminate on the earliest of (a) August 6, 2001, (b) the date of termination by
the Borrower pursuant to Section 2.5(b), and (c) the date of termination by the
Administrative Agent on behalf of the Lenders pursuant to Section 11.2(a).

           SECTION 2.7 Use of Proceeds. The Borrower shall use the proceeds of
the Extensions of Credit to fund working capital and for general corporate
purposes including acquisitions and other permitted investments and to refinance
certain existing indebtedness and the payment of certain fees and expenses
incurred in connection with the transactions contemplated by this Agreement.


                                   ARTICLE III

                            LETTER OF CREDIT FACILITY

           SECTION 3.1 L/C Commitment. Subject to the terms and conditions
hereof, the Issuing Lender agrees to issue standby letters of credit ("Letters
of Credit") for the account of the Borrower on any Business Day from the Closing
Date through but not including the Revolving Credit Termination Date in such
form as may be approved from time to time by the Issuing Lender; provided, that
the Issuing Lender shall have no obligation to issue any Letter of Credit if,
after giving effect to such issuance, (a) the L/C Obligations would exceed the
lesser of (i) the L/C Commitment or (ii) the Aggregate Commitment less the sum
of the Dollar Amount of the aggregate principal amount of all loans or (b) the
Available Commitment of any Lender would be less than zero. Each Letter of
Credit shall (i) be denominated in Dollars in a minimum amount of $50,000, (ii)
be a standby letter of credit issued to support obligations of the Borrower or
any of its Subsidiaries, contingent or otherwise, incurred in the ordinary
course of business or otherwise for a purpose consistent with the permitted use
of proceeds described in Section 2.7, (iii) expire no later than the earlier of
(x) the date which is 365 days after the issuance thereof and (y) the Revolving
Credit Termination Date, and (iv) be subject to the Uniform Customs and, to the
extent not inconsistent therewith, the laws of the State of North Carolina. The
Issuing Lender shall not at any time be obligated to issue any Letter of Credit
hereunder if such issuance would conflict with, or cause the Issuing Lender or
any L/C Participant to exceed any limits imposed by, any Applicable Law.
References herein to "issue" and derivations thereof with respect to Letters of
Credit shall also include extensions or modifications of any existing Letters of
Credit, unless the context otherwise requires.


                                       19
<PAGE>   26

           SECTION 3.2 Procedure for Issuance of Letters of Credit. The Borrower
may from time to time request that the Issuing Lender issue a Letter of Credit
by delivering to the Issuing Lender at the Administrative Agent's Office an
Application therefor, completed to the satisfaction of the Issuing Lender, and
such other certificates, documents and other papers and information as the
Issuing Lender may request. Upon receipt of any Application, the Issuing Lender
shall 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, subject to Section 3.1 and Article V hereof,
promptly issue the Letter of Credit requested thereby (but in no event shall the
Issuing Lender be required to issue any Letter of Credit earlier than two (2)
Business Days after its receipt of the Application therefor and all such other
certificates, documents and other papers and information relating thereto) by
issuing the original of such Letter of Credit to the beneficiary thereof or as
otherwise may be agreed by the Issuing Lender and the Borrower. The Issuing
Lender shall furnish to the Borrower a copy of such Letter of Credit and furnish
to each Lender a copy of such Letter of Credit and the amount of each Lender's
L/C Participation therein, all promptly following the issuance of such Letter of
Credit.

           SECTION 3.3 Commissions and Other Charges.

           (a) The Borrower shall pay to the Administrative Agent, for the
account of the Issuing Lender and the L/C Participants, a letter of credit
commission with respect to each Letter of Credit in an amount equal to the
Applicable Margin with respect to LIBOR Rate Loans per annum on the face amount
of such Letter of Credit. Such commission shall be payable quarterly in arrears
on the last Business Day of each calendar quarter and on the Revolving Credit
Termination Date.

           (b) The Administrative Agent shall, promptly following its receipt
thereof, distribute to the Issuing Lender and the L/C Participants all
commissions received by the Administrative Agent in accordance with their
respective Commitment Percentages.

           SECTION 3.4 [Intentionally Omitted].

           SECTION 3.5 Reimbursement Obligation of the Borrower. The Borrower
agrees to reimburse the Issuing Lender on each date on which the Issuing Lender
notifies the Borrower of the date and amount of a draft paid under any Letter of
Credit for the amount of (a) such draft so paid and (b) any taxes, fees, charges
or other costs or expenses incurred by the Issuing Lender in connection with
such payment. Each such payment shall be made to the Issuing Lender at its
address for notices specified herein in Dollars and in immediately available
funds. Interest shall be payable on any and all amounts remaining unpaid by the
Borrower under this Article III 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 Base Rate Loans which were
then overdue. If the Borrower fails to timely reimburse the Issuing Lender on
the date the Borrower receives the notice referred to in this Section 3.5, the
Borrower shall be deemed to have timely given a Notice of Borrowing hereunder to
the Administrative Agent requesting the Lenders to make a Base Rate Loan on such
date in an amount equal to the amount of such drawing and, regardless of whether
or not the conditions precedent specified in Article V have been satisfied, the
Lenders shall 



                                       20
<PAGE>   27

make Base Rate Loans in such amount, the proceeds of which shall be applied to
reimburse the Issuing Lender for the amount of the related drawing and costs and
expenses.

           SECTION 3.6 Obligations Absolute. The Borrower's obligations under
this Article III (including without limitation the Reimbursement Obligation)
shall be absolute and unconditional under any and all circumstances and
irrespective of any set-off, counterclaim or defense to payment which the
Borrower may have or have had against the Issuing Lender or any beneficiary of a
Letter of Credit. The Borrower also agrees with the Issuing Lender that the
Issuing Lender shall not be responsible for, and the Borrower's Reimbursement
Obligation under Section 3.5 shall not be affected by, among other things, 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 any
dispute between or among the Borrower and any beneficiary of any Letter of
Credit or any other party to which such Letter of Credit may be transferred or
any claims whatsoever of a Borrower against any beneficiary of such Letter of
Credit or any such transferee. The Issuing Lender shall not 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, except for errors or omissions caused by the Issuing Lender's gross
negligence or willful misconduct. The Borrower agrees that any action taken or
omitted by the Issuing Lender 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 Customs and, to the extent not inconsistent therewith, the UCC shall
be binding on the Borrower and shall not result in any liability of the Issuing
Lender to the Borrower. The responsibility of the Issuing Lender to the Borrower
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.

           SECTION 3.7 Effect of Application. To the extent that any provision
of any Application related to any Letter of Credit is inconsistent with the
provisions of this Article III, the provisions of this Article III shall apply.

                                   ARTICLE IV

                             GENERAL LOAN PROVISIONS

           SECTION 4.1 Interest.

           (a) Interest Rate Options. Subject to the provisions of this Section
4.1, at the election of the Borrower, (i) the Loans or any portion thereof shall
bear interest at (A) the Base Rate plus the Applicable Margin as set forth in
Section 4.1(c) or (B) the LIBOR Rate plus the Applicable Margin as set forth in
Section 4.1(c) or (C) the LIBOR Market Rate plus the Applicable Margin as set
forth in Section 4.1(c); provided that the LIBOR Rate shall not be available
until three (3) Business Days after the Closing Date and provided further that
the Borrower shall only be permitted to request Base Rate Loans and LIBOR Market
Rate Loans to be denominated in an Alternative Currency if 



                                       21
<PAGE>   28

such Alternative Currency is available to the Lenders at such rate. The Borrower
shall select the rate of interest and Interest Period, if any, applicable to any
Loan at the time a Notice of Borrowing is given pursuant to Section 2.2 or at
the time a Notice of Conversion/Continuation is given pursuant to Section 4.2.
Each Loan or portion thereof bearing interest based on the Base Rate shall be a
"Base Rate Loan", each Loan or portion thereof bearing interest based on the
LIBOR Rate shall be a "LIBOR Rate Loan" and each Loan or portion thereof bearing
interest based on the LIBOR Market Rate shall be a "LIBOR Market Rate Loan." Any
Loan or any portion thereof as to which the Borrower has not duly specified an
interest rate as provided herein shall be deemed a Base Rate Loan denominated in
Dollars.

           (b) Interest Periods. In connection with each LIBOR Rate Loan, the
Borrower, by giving notice at the times described in Section 4.1(a), shall elect
an interest period (each, an "Interest Period") to be applicable to such Loan,
which Interest Period shall be a period of one (1), two (2), three (3), or six
(6) months with respect to each LIBOR Rate Loan; provided that:

                      (i) the Interest Period shall commence on the date of
advance of or conversion to any LIBOR Rate Loan and, in the case of immediately
successive Interest Periods, each successive Interest Period shall commence on
the date on which the next preceding Interest Period expires;

                      (ii) if any Interest Period would otherwise expire on a
day that is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day; provided, that if any Interest Period with respect to a
LIBOR Rate Loan would otherwise expire on a day that is not a Business Day but
is a day of the month after which no further Business Day occurs in such month,
such Interest Period shall expire on the next preceding Business Day;

                      (iii) any Interest Period with respect to a LIBOR Rate
Loan that begins on the last Business Day of a calendar month (or on a day for
which there is no numerically corresponding day in the calendar month at the end
of such Interest Period) shall end on the last Business Day of the relevant
calendar month at the end of such Interest Period;

                      (iv) no Interest Period shall extend beyond the Revolving
Credit Termination Date; and

                      (v) there shall be no more than eight (8) Interest Periods
outstanding at any time.

           (c) Applicable Margin. The Applicable Margin provided for in Section
4.1(a) with respect to the Loans (the "Applicable Margin") shall (i) on the
Closing Date equal the percentages set forth in the certificate delivered
pursuant to Section 5.2(d)(ii) and (ii) for each fiscal quarter thereafter be
determined by reference to the Debt to Capitalization Ratio or if the Borrower
has made a Rating Election (as defined below) pursuant to Section 4.1(d), the
senior unsecured Debt rating of the Borrower as determined by Standard & Poor's
(the "Senior Unsecured Debt Rating") 



                                       22

as of the end of the fiscal quarter immediately preceding the delivery of the
applicable Officer's Compliance Certificate as follows:

</TABLE>

           "Debt to Capitalization Ratio" means, at any date of determination,
the ratio of Total Debt to Total Capitalization of the Borrower and its
Subsidiaries. Adjustments, if any, in the Applicable Margin shall be made by the
Administrative Agent on the tenth (10th) Business Day after receipt by the
Administrative Agent of quarterly financial statements for the Borrower and its
Subsidiaries and the accompanying Officer's Compliance Certificate setting forth
the Debt to Capitalization Ratio or Senior Unsecured Debt Rating, as applicable,
of the Borrower and its Subsidiaries as of the most recent fiscal quarter end.
Subject to Section 4.1(d), in the event the Borrower fails to deliver such
financial statements and certificate within the time required by Section 7.1(a)
hereof, the Applicable Margin shall be the highest Applicable Margin set forth
above until the delivery of such financial statements and certificate.

           (d) Rating Election. So long as no Default or Event of Default has
occurred and is continuing, at any date after the Borrower has obtained an
investment-grade debt rating, the Borrower may make a one-time election while
such investment-grade rating remains in effect (such election, the "Rating
Election") as to whether the Debt to Capitalization Ratio or the Senior
Unsecured Debt Rating shall be the basis for determining the Applicable Margin
pursuant to Section 4.1(c).

           (e) Default Rate. Subject to Section 11.3, at the discretion of the
Administrative Agent and Required Lenders, upon the occurrence and during the
continuance of an Event of Default, (i) the Borrower shall no longer have the
option to request LIBOR Rate Loans, (ii) all outstanding LIBOR Rate Loans shall
bear interest at a rate per annum two percent (2%) in excess of the rate then
applicable to LIBOR Rate Loans, until the end of the applicable Interest Period
and thereafter at a rate equal to two percent (2%) in excess of the rate then
applicable to Base Rate Loans, (iii) all outstanding LIBOR Market Rate Loans
shall bear interest at a rate per annum equal to two percent (2%) in excess of
the rate then applicable to Base Rate Loans and (iv) all outstanding Base Rate
Loans shall bear interest at a rate per annum equal to two percent (2%) in
excess of the rate then applicable to Base Rate Loans. Interest shall continue
to accrue on the Notes after the filing by or against the Borrower of any
petition seeking any relief in bankruptcy or under any act or law pertaining to
insolvency or debtor relief, whether state, federal or foreign.



                                       23
<PAGE>   30

           (f) Payment and Computation of Interest and Fees. All fees hereunder
and interest on each Base Rate Loan and each LIBOR Market Rate Loan shall be
payable in arrears on the last Business Day of each calendar quarter commencing
September 30, 1998; and interest on each LIBOR Rate Loan shall be payable on the
last day of each Interest Period applicable thereto, and if such Interest Period
extends over three (3) months, at the end of each three (3) month interval
during such Interest Period. Interest on LIBOR Rate Loans (except for
Alternative Currency Loans denominated in Pounds Sterling which shall be
computed on the basis of a 365/66-day year) and LIBOR Market Rate Loans and all
fees payable hereunder shall be computed on the basis of a 360-day year and
assessed for the actual number of days elapsed and interest on Base Rate Loans
shall be computed on the basis of a 365/66-day year and assessed for the actual
number of days elapsed.

           (g) Maximum Rate. In no contingency or event whatsoever shall the
aggregate of all amounts deemed interest hereunder or under any of the Notes
charged or collected pursuant to the terms of this Agreement or pursuant to any
of the Notes exceed the highest rate permissible under any Applicable Law which
a court of competent jurisdiction shall, in a final determination, deem
applicable hereto. In the event that such a court determines that the Lenders
have charged or received interest hereunder in excess of the highest applicable
rate, the rate in effect hereunder shall automatically be reduced to the maximum
rate permitted by Applicable Law and the Lenders shall at the Administrative
Agent's option (i) promptly refund to the Borrower any interest received by
Lenders in excess of the maximum lawful rate or (ii) shall apply such excess to
the principal balance of the Obligations. It is the intent hereof that the
Borrower not pay or contract to pay, and that neither the Administrative Agent
nor any Lender receive or contract to receive, directly or indirectly in any
manner whatsoever, interest in excess of that which may be paid by the Borrower
under Applicable Law.

           SECTION 4.2 Notice and Manner of Conversion or Continuation of Loans.
Provided that no Event of Default has occurred and is then continuing, the
Borrower shall have the option to (a) convert at any time following the third
Business Day after the Closing Date all or any portion of its outstanding Base
Rate Loans or LIBOR Market Rate Loans in a principal amount equal to $3,000,000
or any whole multiple of $1,000,000 in excess thereof into one or more LIBOR
Rate Loans denominated in Dollars, (b) upon the expiration of any Interest
Period, convert all or any part of its outstanding LIBOR Rate Loans denominated
in Dollars in a principal amount equal to $100,000 or a whole multiple of
$50,000 in excess thereof into Base Rate Loans or LIBOR Market Rate Loans or (c)
upon the expiration of any Interest Period, continue any LIBOR Rate Loan
denominated in any Permitted Currency in a principal amount of $3,000,000 or any
whole multiple of $1,000,000 in excess thereof (or with respect to LIBOR Rate
Loans denominated in an Alternative Currency, the Alternative Currency Amount in
each case thereof) as a LIBOR Rate Loan in the same Permitted Currency. Whenever
the Borrower desires to convert or continue Loans as provided above, the
Borrower shall give the Administrative Agent irrevocable prior written notice in
the form attached as Exhibit E (a "Notice of Conversion/ Continuation") not
later than 11:00 a.m. (Charlotte time) four (4) Business Days before (with
respect to any LIBOR Rate Loan denominated in an Alternative Currency), two (2)
Business Days before (with respect to any LIBOR Market Rate Loan or Base Rate
Loan denominated in an Alternative Currency) and the same Business Day of (with
respect to any Loan denominated in Dollars) the day on which a 



                                       24
<PAGE>   31

proposed conversion or continuation of such Loan is to be effective specifying
(A) the Loans to be converted or continued, the Permitted Currency in which such
Loan is denominated and, in the case of any LIBOR Rate Loan to be converted or
continued, the last day of the Interest Period therefor, (B) the effective date
of such conversion or continuation (which shall be a Business Day), (C) the
principal amount of such Loans to be converted or continued, and (D) the
Interest Period to be applicable to such converted or continued LIBOR Rate Loan.
The Administrative Agent shall promptly notify the Lenders of such Notice of
Conversion/Continuation.

           SECTION 4.3 Fees.

           (a) Facility Fees. The Borrower shall pay to the Administrative
Agent, for the account of the Lenders, a non-refundable facility fee on the
entire amount of the Aggregate Commitment, regardless of usage at a rate per
annum determined by reference to the Debt to Capitalization Ratio or Senior
Unsecured Debt Rating, as applicable, as of the end of the fiscal quarter
immediately preceding the delivery of the applicable Officer's Compliance
Certificate as follows:

  Debt to Capitalization        Senior Unsecured Debt       Facility Fee
           Ratio                       Rating
  ----------------------        ---------------------       ------------

-
> 0.35 to 1.00                          > BBB-                0.150%
-                                       -
> 0.30 to 1.00                          > BBB                  0125%
-                                       -
> 0.25 to 1.00                          > BBB+                0.100%
-                                       -
<0.25 to 1.00                           > A-                  0.080%
                                        -

           (b) Administrative Agent's and Other Fees. In order to compensate the
Administrative Agent for structuring and syndicating the Loans and for its
obligations hereunder, the Borrower agrees to pay to the Administrative Agent,
for its account, the fees set forth in the separate fee letter agreement
executed by the Borrower and the Administrative Agent dated June 9, 1998.

           SECTION 4.4 Manner of Payment.

           (a) Loans Denominated in Dollars. Each payment (including repayments
described in Article II) by the Borrower on account of the principal of or
interest on the Loans denominated in Dollars or of any fee, commission or other
amounts (including the Reimbursement Obligation) payable to the Lenders under
this Agreement or any Note (except as set forth in Section 4.4(b)) shall be made
in Dollars not later than 1:00 p.m. (Charlotte time) on the date specified for
payment under this Agreement to the Administrative Agent at the Administrative
Agent's Office for the account of the Lenders (other than as set forth below)
pro rata in accordance with their respective Commitment Percentages (other than
as set forth below) in immediately available funds and shall be made without any
set-off, counterclaim or deduction whatsoever. Any payment received after such
time but before 2:00 p.m. (Charlotte time) on such day shall be deemed a payment
on such date for the purposes of Section 11.1, but for all other purposes shall
be deemed to have been made on the next 



                                       25
<PAGE>   32

succeeding Business Day. Any payment received after 2:00 p.m. (Charlotte time)
shall be deemed to have been made on the next succeeding Business Day for all
purposes.

           (b) Alternative Currency Loans. Each payment (including repayments
described in Article II) by the Borrower on account of the principal of or
interest on the Loans denominated in any Alternative Currency shall be made in
such Alternative Currency not later than 11:00 a.m. (the time of the
Administrative Agent's Correspondent) on the date specified for payment under
this Agreement to the Administrative Agent's account with the Administrative
Agent's Correspondent for the account of the Lenders (other than as set forth
below) pro rata in accordance with their respective Commitment Percentages
(other than as set forth below) in immediately available funds, and shall be
made without any set-off, counterclaim or deduction whatsoever. Any payment
received after such time but before 12:00 noon (the time of the Administrative
Agent's Correspondent) on such day shall be deemed a payment on such date for
the purposes of Section 11.1, but for all other purposes shall be deemed to have
been made on the next succeeding Business Day. Any payment received after 12:00
noon (the time of the Administrative Agent's Correspondent) shall be deemed to
have been made on the next succeeding Business Day for all purposes.

           (c) Pro Rata Treatment. Upon receipt by the Administrative Agent of
each such payment, the Administrative Agent shall distribute to each Lender at
its address for notices set forth herein its pro rata share of such payment in
accordance with such Lender's Commitment Percentage (except as specified below)
and shall wire advice of the amount of such credit to each Lender. Each payment
to the Administrative Agent of the Issuing Lender's fees or L/C Participants'
commissions shall be made in like manner, but for the account of the Issuing
Lender or the L/C Participants, as the case may be. Each payment to the
Administrative Agent of Administrative Agent's fees or expenses shall be made
for the account of the Administrative Agent and any amount payable to any Lender
under Sections 4.10, 4.11, 4.12, 4.13, 13.2 or 13.10(i) shall be paid to the
Administrative Agent for the account of the applicable Lender. Subject to
Section 4.1(b)(ii) if any payment under this Agreement or any Note shall be
specified to be made upon a day which is not a Business Day, it shall be made on
the next succeeding day which is a Business Day and such extension of time shall
in such case be included in computing any interest if payable along with such
payment.

           SECTION 4.5 Crediting of Payments and Proceeds. In the event that the
Borrower shall fail to pay any of the Obligations when due and the Obligations
have been accelerated pursuant to Section 11.2, all payments received by the
Lenders upon the Notes and the other Obligations and all net proceeds from the
enforcement of the Obligations shall be applied first to all expenses then due
and payable by the Borrower hereunder, then to all indemnity obligations then
due and payable by the Borrower hereunder, then to all Administrative Agent's
and Issuing Lender's fees then due and payable, then to all commitment and other
fees and commissions then due and payable, then to accrued and unpaid interest
on the Notes, the Reimbursement Obligation and any termination payments due in
respect of a Hedging Agreement with any Lender (which such Hedging Agreement is
permitted or required hereunder) (pro rata in accordance with all such amounts
due), then to the principal amount of the Notes and Reimbursement Obligation and
then to 



                                       26
<PAGE>   33

the cash collateral account described in Section 11.2(b) hereof to the extent of
any L/C Obligations then outstanding, in that order.

           SECTION 4.6 Adjustments. If any Lender (a "Benefited Lender") shall
at any time receive any payment of all or part of the Obligations owing to it,
or interest thereon, or if any Lender shall at any time receive any collateral
in respect to the Obligations owing to it (whether voluntarily or involuntarily,
by set-off or otherwise) in a greater proportion than any such payment to and
collateral received by any other Lender, if any, in respect of the Obligations
owing to such other Lender, or interest thereon, such Benefited Lender shall
purchase for cash from the other Lenders such portion of each such other
Lender's Extensions of Credit, 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; provided, 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
Borrower agrees that each Lender so purchasing a portion of another Lender's
Extensions of Credit 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.

           SECTION 4.7 Nature of Obligations of Lenders Regarding Extensions of
Credit; Assumption by the Administrative Agent. The obligations of the Lenders
under this Agreement to make the Loans and issue or participate in Letters of
Credit are several and are not joint or joint and several. Unless the
Administrative Agent shall have received notice from a Lender prior to a
proposed borrowing date that such Lender will not make available to the
Administrative Agent such Lender's ratable portion of the amount to be borrowed
on such date (which notice shall not release such Lender of its obligations
hereunder), the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the proposed borrowing date in
accordance with Section 2.2(b) and the Administrative Agent may, in reliance
upon such assumption, make available to the Borrower on such date a
corresponding amount. If such amount is made available to the Administrative
Agent on a date after such borrowing date, such Lender shall pay to the
Administrative Agent on demand an amount, until paid, equal to (a) with respect
to a Loan denominated in Dollars, the product of (i) the amount not made
available by such Lender in accordance with the terms hereof, times (ii) the
daily average Federal Funds Rate during such period as determined by the
Administrative Agent, times (iii) a fraction the numerator of which is the
number of days that elapse from and including such borrowing date to the date on
which such amount not made available by such Lender in accordance with the terms
hereof shall have become immediately available to the Administrative Agent and
the denominator of which is 360 and (b) with respect to a loan denominated in an
Alternative Currency the amount not made available by such Lender in accordance
with the terms hereof and interest thereon at a rate per annum equal to the
Administrative Agent's aggregate marginal cost (including the cost of
maintaining any required reserves or deposit insurance and of any fees,
penalties, overdraft charges or other costs or expenses incurred by the
Administrative Agent as a result of the failure to deliver funds hereunder) of
carrying such amount. A certificate of the Administrative Agent with respect to
any amounts owing under this Section shall be conclusive, absent manifest error.
If such Lender's Commitment 



                                       27
<PAGE>   34

Percentage of such borrowing is not made available to the Administrative Agent
by such Lender within three (3) Business Days of such borrowing date, the
Administrative Agent shall be entitled to recover such amount made available by
the Administrative Agent with interest thereon at the rate per annum applicable
to LIBOR Market Rate Loans hereunder, on demand, from the Borrower. The failure
of any Lender to make available its Commitment Percentage of any Loan requested
by the Borrower shall not relieve it or any other Lender of its obligation, if
any, hereunder to make its Commitment Percentage of such Loan available on the
borrowing date, but no Lender shall be responsible for the failure of any other
Lender to make its Commitment Percentage of such Loan available on the borrowing
date.

           SECTION 4.8 Mandatory Redenomination of Alternative Currency Loans.

           (a) If any LIBOR Rate Loan or LIBOR Market Rate Loan is required to
be converted to a Base Rate Loan pursuant to Section 4.1(e), Section 4.10 or any
other applicable provision hereof, such Loan shall be funded in Dollars in an
amount equal to the Dollar Amount of such Loan, all subject to the provisions of
Section 2.3(b). The Borrower shall reimburse the Lenders upon any such
conversion for any amounts required to be paid under Section 4.11 hereof.

           (b) If, as a result of the implementation of the European economic
and monetary union ("EMU"), (i) any Alternative Currency ceases to be lawful
currency of the nation issuing the same and is replaced by a European common
currency (the "Euro") or (ii) any Alternative Currency and the Euro are at the
same time recognized by any governmental authority of the nation issuing such
Alternative Currency as lawful currency of such nation, then any amount payable
hereunder by the Borrower in such Alternative Currency shall instead by payable
in the Euro and the amount so payable shall be determined by translating the
amount so payable in such other Alternative Currency to the Euro at the exchange
rate recognized by the european central bank (or such other governmental or
regulatory authority designated by the EMU for establishing such exchange rate)
for the purpose of implementing the EMU. Prior to the occurrence of the event or
events described in clause (i) or (ii) of the preceding sentence, each amount
payable hereunder in any Alternative Currency will, except as otherwise provided
herein, continue to be payable only in that Alternative Currency.

           (c) The terms and provisions of this Agreement will be subject to
such reasonable changes of construction as determined by the Administrative
Agent (acting reasonably and in consultation with the Borrower) to reflect such
implementation of the Euro and to put the Lenders and the Borrower in the same
position, so far as possible, that they would have been if such implementation
had not occurred. Except as provided in the foregoing provisions of this Section
4.8, no such implementation nor any economic consequences resulting therefrom
shall give rise to any right to terminate, contest, cancel, modify or
renegotiate the provisions of this Agreement.

           SECTION 4.9 Regulatory Limitation. In the event, as a result of
increases in the value of Alternative Currencies against the Dollar or for any
other reason, the obligation of any of the Lenders to make Loans (taking into
account the Dollar Amount of the Obligations and all other 



                                       28
<PAGE>   35

indebtedness required to be aggregated under 12 U.S.C.A. ss.84, as amended, the
regulations promulgated thereunder and any other Applicable Law) is determined
by such Lender to exceed its then applicable legal lending limit under 12
U.S.C.A. ss.84, as amended, and the regulations promulgated thereunder, or any
other Applicable Law, the amount of additional Extensions of Credit such Lender
shall be obligated to make or issue or participate in hereunder shall
immediately be reduced to the maximum amount which such Lender may legally
advance (as determined by such Lender), the obligation of each of the remaining
Lenders hereunder shall be proportionately reduced, based on their applicable
Commitment Percentages and, to the extent necessary under such laws and
regulations (as determined by each of the Lenders, with respect to the
applicability of such laws and regulations to itself), and the Borrower shall
reduce, or cause to be reduced, complying to the extent practicable with the
remaining provisions hereof, the Obligations outstanding hereunder by an amount
sufficient to comply with such maximum amounts.

           SECTION 4.10 Changed Circumstances.

           (a) Circumstances Affecting LIBOR Rate, LIBOR Market Rate Loans and
Alternative Currency Availability. If with respect to any Interest Period the
Administrative Agent or any Lender (after consultation with the Administrative
Agent) shall determine that (i) by reason of circumstances affecting the foreign
exchange and interbank markets generally, deposits in eurodollars or an
Alternative Currency in the applicable amounts are not being quoted via Dow
Jones Markets screen 3750 or offered to the Administrative Agent or such Lender
for such Interest Period, (ii) a fundamental change has occurred in the foreign
exchange or interbank markets with respect to any Alternative Currency
(including, without limitation, fundamental changes in national or international
financial, political or economic conditions or currency exchange rates or
exchange controls) or (iii) it has become otherwise materially impractical for
the Administrative Agent or the Lenders to make such Loan in an Alternative
Currency, then the Administrative Agent shall forthwith give notice thereof to
the Borrower. Thereafter, until the Administrative Agent notifies the Borrower
that such circumstances no longer exist (which notification the Administrative
Agent shall give to the Borrower promptly upon learning that such circumstances
no longer exist), the obligation of the Lenders to make LIBOR Rate Loans, LIBOR
Market Rate Loans or Alternative Currency Loans, as applicable, and the right of
the Borrower to convert any Loan to or continue any Loan as a LIBOR Rate Loan,
LIBOR Market Rate Loan or a Alternative Currency Loan, as applicable, shall be
suspended, and the Borrower shall repay in full (or cause to be repaid in full)
the then outstanding principal amount of each such LIBOR Rate Loans, LIBOR
Market Rate Loans or Alternative Currency Loan, as applicable, together with
accrued interest thereon, on the last day of the then current Interest Period
applicable to such LIBOR Rate Loan, LIBOR Market Rate Loan or Alternative
Currency Loan, as applicable, or convert the then outstanding principal amount
of each such LIBOR Rate Loan, LIBOR Market Rate Loan or Alternative Currency
Loan, as applicable, to a Base Rate Loan as of the last day of such Interest
Period.

           (b) Laws Affecting LIBOR Rate, LIBOR Market Rate and Alternative
Currency Availability. If, after the date hereof, the introduction of, or any
change in, any Applicable Law or any change in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance




                                       29
<PAGE>   36

by any Lender (or any of their respective Lending Offices) with any request or
directive (whether or not having the force of law) of any such Governmental
Authority, central bank or comparable agency, shall make it unlawful or
impossible for any of the Lenders (or any of their respective Lending Offices)
to honor its obligations hereunder to make or maintain any LIBOR Rate Loan,
LIBOR Market Rate Loan or any Alternative Currency Loan, such Lender shall
promptly give notice thereof to the Administrative Agent and the Administrative
Agent shall promptly give notice to the Borrower and the other Lenders.
Thereafter, until the Administrative Agent notifies the Borrower that such
circumstances no longer exist (which notification the Administrative Agent shall
give to the Borrower promptly upon learning that such circumstances no longer
exist), (i) the obligations of the Lenders to make LIBOR Rate Loans, LIBOR
Market Rate Loans or Alternative Currency Loans, as applicable, and the right of
the Borrower to convert any Loan or continue any Loan as a LIBOR Rate Loan,
LIBOR Market Rate Loan or Alternative Currency Loan, as applicable, shall be
suspended and thereafter the Borrower may select only Base Rate Loans hereunder,
and (ii) if any of the Lenders may not lawfully continue to maintain a LIBOR
Rate Loan, LIBOR Market Rate Loan or Alternative Currency Loan, as applicable,
to the end of the then current Interest Period applicable thereto as a LIBOR
Rate Loan, LIBOR Market Rate Loan or Alternative Currency Loan, as applicable,
the applicable LIBOR Rate Loan, LIBOR Market Rate Loan or Alternative Currency
Loan, as applicable, shall immediately be converted to a Base Rate Loan for the
remainder of such Interest Period.

           (c) Increased Costs. If, after the date hereof, the introduction of,
or any change in, any Applicable Law, or in the interpretation or administration
thereof by any Governmental Authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any of the
Lenders (or any of their respective Lending Offices) with any request or
directive (whether or not having the force of law) of such Governmental
Authority, central bank or comparable agency:

                      (i) shall subject any of the Lenders (or any of their
respective Lending Offices) to any tax, duty or other charge with respect to any
Note, Letter of Credit or Application or shall change the basis of taxation of
payments to any of the Lenders (or any of their respective Lending Offices) of
the principal of or interest on any Note, Letter of Credit or Application or any
other amounts due under this Agreement in respect thereof (except for changes in
the rate of tax on the overall net income of any of the Lenders or any of their
respective Lending Offices imposed by the jurisdiction in which such Lender is
organized or is or should be qualified to do business or such Lending Office is
located); or

                      (ii) shall impose, modify or deem applicable any reserve
(including, without limitation, any imposed by the Board of Governors of the
Federal Reserve System), special deposit, insurance or capital or similar
requirement against assets of, deposits with or for the account of, or credit
extended by any of the Lenders (or any of their respective Lending Offices) or
shall impose on any of the Lenders (or any of their respective Lending Offices)
or the foreign exchange and interbank markets any other condition affecting any
Note;


                                       30
<PAGE>   37

and the result of any of the foregoing is to increase the costs to any of the
Lenders of maintaining any LIBOR Rate Loan, LIBOR Market Rate Loan or
Alternative Currency Loan, as applicable, or issuing or participating in Letters
of Credit or to reduce the yield or amount of any sum received or receivable by
any of the Lenders under this Agreement or under the Notes in respect of a LIBOR
Rate Loan, LIBOR Market Rate Loan or Alternative Currency Loan, as applicable,
or Letter of Credit or Application, then such Lender may notify the
Administrative Agent, upon the receipt of which the Administrative Agent shall
promptly notify the Borrower of such fact and, if requested to do so by the
Lender, shall demand compensation therefor and, within thirty (30) days after
such notice by the Administrative Agent, the Borrower shall pay to such Lender
such additional amount or amounts as will compensate such Lender or Lenders for
such increased cost or reduction. The Administrative Agent will promptly notify
the Borrower of any event of which it has knowledge which will entitle such
Lender to compensation pursuant to this Section 4.10(c); provided, that the
Administrative Agent shall incur no liability whatsoever to the Lenders or the
Borrower in the event it fails to do so. The amount of such compensation shall
be determined, in the applicable Lender's reasonable discretion, based upon the
assumption that such Lender funded its Commitment Percentage of the LIBOR Rate
Loans, LIBOR Market Rate Loans or Alternative Currency Loans as applicable, in
the London interbank market and using any reasonable attribution or averaging
methods which such Lender deems appropriate and practical. A certificate of such
Lender setting forth the basis for determining such amount or amounts necessary
to compensate such Lender shall be forwarded to the Borrower through the
Administrative Agent and shall be conclusively presumed to be correct save for
manifest error.

           SECTION 4.11 Indemnity. The Borrower hereby indemnifies each of the
Lenders against any loss or expense (including, without limitation, any foreign
exchange costs) which may arise or be attributable to each Lender's obtaining,
liquidating or employing deposits or other funds acquired to effect, fund or
maintain any Loan (a) as a consequence of any failure by the Borrower to make
any payment when due of any amount due hereunder in connection with a LIBOR Rate
Loan or LIBOR Market Rate Loan, (b) due to any failure of the Borrower to borrow
on a date specified therefor in a Notice of Borrowing or Notice of
Continuation/Conversion or (c) due to any payment, prepayment or conversion of
any LIBOR Rate Loan or LIBOR Market Rate Loan on a date other than the last day
of the Interest Period therefor. The amount of such loss or expense shall be
determined, in the applicable Lender's reasonable discretion, based upon the
assumption that such Lender funded its Commitment Percentage of the LIBOR Rate
Loans or LIBOR Market Rate Loans in the London interbank market and using any
reasonable attribution or averaging methods which such Lender deems appropriate
and practical. A certificate of such Lender setting forth the basis for
determining such amount or amounts necessary to compensate such Lender shall be
forwarded to the Borrower through the Administrative Agent and shall be
conclusively presumed to be correct save for manifest error.

           SECTION 4.12 Capital Requirements. If either (a) the introduction of,
or any change in, or in the interpretation of, any Applicable Law or (b)
compliance with any guideline or request from any central bank or comparable
agency or other Governmental Authority (whether or not having the force of law),
has or would have the effect of reducing the rate of return on the capital of,
or has affected or would affect the amount of capital required to be maintained
by, any 



                                       31
<PAGE>   38

Lender or any corporation controlling such Lender as a consequence of, or with
reference to the Commitments and other commitments of this type, below the rate
which the Lender or such other corporation could have achieved but for such
introduction, change or compliance, then within fifteen (15) Business Days after
written demand by any such Lender, the Borrower shall pay to such Lender from
time to time as specified by such Lender additional amounts sufficient to
compensate such Lender or other corporation for such reduction. A certificate as
to such amounts submitted to the Borrower and the Administrative Agent by such
Lender, shall, in the absence of manifest error, be presumed to be correct and
binding for all purposes.

           SECTION 4.13 Taxes.

           (a) Payments Free and Clear. Any and all payments by the Borrower
hereunder or under the Notes or the Letters of Credit shall be made free and
clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholding, and all liabilities with respect
thereto excluding, (i) in the case of each Lender and the Administrative Agent,
income and franchise taxes imposed by the jurisdiction under the laws of which
such Lender or the Administrative Agent (as the case may be) is organized or is
or should be qualified to do business or any political subdivision thereof and
(ii) in the case of each Lender, income and franchise taxes imposed by the
jurisdiction of such Lender's Lending Office or any political subdivision
thereof (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as "Taxes"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note or Letter of Credit to any Lender or the
Administrative Agent, (A) the sum payable shall be increased as may be necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 4.13) such Lender or the
Administrative Agent (as the case may be) receives an amount equal to the amount
such party would have received had no such deductions been made, (B) the
Borrower shall make such deductions, (C) the Borrower shall pay the full amount
deducted to the relevant taxing authority or other authority in accordance with
applicable law, and (D) the Borrower shall deliver to the Administrative Agent
evidence of such payment to the relevant taxing authority or other authority in
the manner provided in Section 4.13(d).

           (b) Stamp and Other Taxes. In addition, the Borrower shall pay any
present or future stamp, registration, recordation or documentary taxes or any
other similar fees or charges or excise or property taxes, levies of the United
States or any state or political subdivision thereof or any applicable foreign
jurisdiction which arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, the
Loans, the Letters of Credit, the other Loan Documents, or the perfection of any
rights or security interest in respect thereto (hereinafter referred to as
"Other Taxes").

           (c) Indemnity. The Borrower shall indemnify each Lender and the
Administrative Agent for the full amount of Taxes and Other Taxes (including,

each case that such Lender is entitled to a complete exemption from withholding
or deduction for or on account of any United States federal income taxes, and
(ii) an Internal Revenue Service Form W-8 or W-9 or successor applicable form,

W-9, or successor applicable forms or manner of certification, as the case may

Agreement without deduction or withholding of any United States federal income
taxes (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 such forms inapplicable or
the exemption to which such forms relate unavailable and such Lender notifies
the Borrower and the Administrative Agent that it is not entitled to receive
payments without deduction or withholding of United States federal income taxes)
and, in the case of a Form W-8 or W-9, establishing an exemption from United
States backup withholding tax.

                                   ARTICLE VI

                 REPRESENTATIONS AND WARRANTIES OF THE BORROWER

           SECTION 6.1 Representations and Warranties. To induce the
Administrative Agent and Lenders to enter into this Agreement and to induce the
Lenders to make Extensions of Credit, the Borrower hereby represents and
warrants to the Administrative Agent and Lenders that:

           (a) Organization; Power; Qualification. The Borrower and each of the
Guarantors is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation or formation, has the power and
authority to own its properties and to carry on its business as now being and
hereafter proposed to be conducted and is duly qualified and authorized to do
business in each jurisdiction in which the character of its properties or the
nature of its business requires such qualification and authorization, except
where the failure to do so could not reasonably be expected to have a Material
Adverse Effect. The jurisdictions in which the Borrower and the Guarantors are
organized and qualified to do business as of the Closing Date are described on
Schedule 6.1(a).

           (b) Ownership. Each Subsidiary of the Borrower as of the Closing Date
is listed on Schedule 6.1(b). As of the Closing Date, the capitalization of the
Borrower and the Guarantors consists of the number of shares, authorized, issued
and outstanding, of such classes and series, with or without par value,
described on Schedule 6.1(b). All outstanding shares have been duly authorized
and validly issued and are fully paid and nonassessable. The shareholders of the
Guarantors of the Borrower and the number of shares owned by each as of the
Closing Date are described on Schedule 6.1(b).

           (c) Authorization of Agreement, Loan Documents and Borrowing. Each of
the Borrower and the Guarantors has the right, power and authority and has taken
all necessary corporate and other action to authorize the execution, delivery
and performance of this Agreement and each of the other Loan Documents to which
it is a party in accordance with their respective terms. This Agreement and each
of the other Loan Documents have been duly executed and delivered by the duly
authorized officers of the Borrower and each of the Guarantors party thereto,
and each such document constitutes the legal, valid and binding obligation of
the Borrower or its Guarantors party thereto, enforceable in accordance with its
terms, except as such enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar state or federal debtor relief laws from
time to time in effect which affect the enforcement of creditors' rights in
general and the availability of equitable remedies.

           (d) Compliance of Agreement, Loan Documents and Borrowing with Laws,
Etc. The execution, delivery and performance by the Borrower and the Guarantors
of the Loan Documents to which each such Person is a party, in accordance with
their respective terms, the borrowings hereunder and the transactions
contemplated hereby do not and will not, by the passage of time, the giving of
notice or otherwise, (i) require any Governmental Approval or violate any
Applicable Law 



                                       37
<PAGE>   44

relating to the Borrower or any of the Guarantors, (ii) conflict with, result in
a breach of or constitute a default under the articles of incorporation, bylaws
or other organizational documents of the Borrower or any of the Guarantors or
any indenture, agreement or other instrument to which such Person is a party or
by which any of its properties may be bound or any Governmental Approval
relating to such Person, or (iii) result in or require the creation or
imposition of any Lien upon or with respect to any property now owned or
hereafter acquired by such Person other than Liens arising under the Loan
Documents.

           (e) Compliance with Law; Governmental Approvals. Each of the Borrower
and the Guarantors (i) has all Governmental Approvals required by any Applicable
Law for it to conduct its business, each of which is in full force and effect,
is final and not subject to review on appeal and is not the subject of any
pending or, to the best of its knowledge, threatened attack by direct or
collateral proceeding, and (ii) is in material compliance with each Governmental
Approval applicable to it and in material compliance with all other Applicable
Laws relating to it or any of its respective properties.

           (f) Tax Returns and Payments. Each of the Borrower and the Guarantors
has duly filed or caused to be filed all federal, state, local and other tax
returns required by Applicable Law to be filed, and has paid, or made adequate
provision for the payment of, all federal, state, local and other taxes,
assessments and governmental charges or levies upon it and its property, income,
profits and assets which are due and payable. No Governmental Authority has
asserted any Lien or other claim against the Borrower or any Guarantor with
respect to unpaid taxes which has not been discharged or resolved. The charges,
accruals and reserves on the books of the Borrower and any of its Subsidiaries
in respect of federal, state, local and other taxes for all Fiscal Years and
portions thereof since the organization of the Borrower and any of its
Subsidiaries are in the judgment of the Borrower adequate, and the Borrower does
not anticipate any additional taxes or assessments for any of such years.

           (g) Intellectual Property Matters. Each of the Borrower and the
Guarantors owns or possesses rights to use all franchises, licenses, copyrights,
copyright applications, patents, patent rights or licenses, patent applications,
trademarks, trademark rights, trade names, trade name rights, copyrights and
rights with respect to the foregoing which are required to conduct its business.
No event has occurred which, to the knowledge of the Borrower or the Guarantors,
permits, or after notice or lapse of time or both would permit, the revocation
or termination of any such rights, and, to the knowledge of the Borrower or the
Guarantors, neither the Borrower nor any Subsidiary thereof is liable to any
Person for infringement under Applicable Law with respect to any such rights as
a result of its business operations.

           (h) Environmental Matters.

                      (i) The properties of the Borrower and the Guarantors do
not contain, and to their knowledge have not previously contained, any Hazardous

                                       38

connection therewith are in material compliance, and have been in material
compliance, with all applicable Environmental Laws, and there is no
contamination at, under or about such properties or such operations which could
interfere with the continued operation of such properties or impair the fair
saleable value thereof;

                      (iii) Neither the Borrower nor any Guarantor thereof has
received any notice of violation, alleged violation, non-compliance, liability

                      (iv) To the knowledge of the Borrower and Guarantors,
Hazardous Materials have not been transported or disposed of from the properties

location reasonably likely to give rise to liability under, Environmental Laws,
nor, to the knowledge of the Borrower and Guarantors, have any Hazardous
Materials been generated, treated, stored or disposed of at, on or under any of
such properties in violation of, or in a manner reasonably likely to give rise
to liability under, any applicable Environmental Laws;

                      (v) No judicial proceedings or governmental or

threatened, under any Environmental Law to which the Borrower or any Guarantor
is or will be named as a party with respect to such properties or operations
conducted in connection therewith, 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
with respect to such properties or such operations; and

                      (vi) To the best of Borrower's knowledge, there has been
no release, or threat of release, of Hazardous Materials at or from such
properties, in violation of or in amounts or in a manner reasonably likely to
give rise to liability under Environmental Laws.

                      (i) As of the Closing Date, neither the Borrower nor any

ERISA Affiliate maintains or contributes to, or has any obligation under, any
Employee Benefit Plans other than those identified on Schedule 6.1(i);

compliance with all applicable provisions of ERISA and the regulations and

                                       39
<PAGE>   46

Benefit Plan that is intended to be qualified under Section 401(a) of the Code
has been determined by the Internal Revenue Service to be so qualified, and each
trust related to such plan has been determined to be exempt under Section 501(a)
of the Code. No liability has been incurred by the Borrower or any ERISA
Affiliate which remains unsatisfied for any taxes or penalties with respect to
any Employee Benefit Plan or any Multiemployer Plan;

                      (iii) No Pension Plan has been terminated, nor has any
accumulated funding deficiency (as defined in Section 412 of the Code) been
incurred (without regard to any waiver granted under Section 412 of the Code),
nor has any funding waiver from the Internal Revenue Service been received or
requested with respect to any Pension Plan, nor has the Borrower or any ERISA
Affiliate failed to make any contributions or to pay any amounts due and owing

Section 3(1) of ERISA) currently maintained or contributed to by the Borrower or
any ERISA Affiliate, (B) Pension Plan or (C) Multiemployer Plan.

           (j) Margin Stock. Neither the Borrower nor any Subsidiary thereof is
engaged principally or as one of its activities in the business of extending
credit for the purpose of "purchasing" or "carrying" any "margin stock" (as each
such term is defined or used in Regulation U of the Board of Governors of the
Federal Reserve System). Not more than twenty-five percent (25%) of the proceeds
of any of the Loans or Letters of Credit will be used for purchasing or carrying
margin stock or for any purpose which violates, or which would be inconsistent
with, the provisions of Regulation T, U or X of such Board of Governors.

           (k) Government Regulation. Neither the Borrower nor any Guarantor
thereof is an "investment company" or a company "controlled" by an "investment
company" (as each such term is defined or used in the Investment Company Act of
1940, as amended) and neither the Borrower nor any Subsidiary thereof is, or
after giving effect to any Extension of Credit will be, subject to 



                                       40
<PAGE>   47

regulation under the Public Utility Holding Company Act of 1935 or the
Interstate Commerce Act, each as amended, or any other Applicable Law which
limits its ability to incur or consummate the transactions contemplated hereby.

           (l) Material Contracts. Schedule 6.1(l) sets forth a complete and
accurate list of all Material Contracts of the Borrower and its Subsidiaries in
effect as of the Closing Date not listed on any other Schedule hereto; other
than as set forth in Schedule 6.1(l), each such Material Contract is, and after
giving effect to the consummation of the transactions contemplated by the Loan
Documents will be, in full force and effect in accordance with the terms
thereof. The Borrower and its Subsidiaries have delivered to the Administrative
Agent a true and complete copy of each Material Contract required to be listed
on Schedule 6.1(l) or any other Schedule hereto.

           (m) Employee Relations. Each of the Borrower and the Guarantors is
not, as of the Closing Date, party to any collective bargaining agreement nor
has any labor union been recognized as the representative of its employees. The
Borrower knows of no pending, threatened or contemplated strikes, work stoppage
or other collective labor disputes involving its employees or those of the
Guarantors.

           (n) Burdensome Provisions. Neither the Borrower nor any Guarantor is
a party to any indenture, agreement, lease or other instrument, or subject to
any corporate or partnership restriction, Governmental Approval or Applicable
Law which is so unusual or burdensome as to be likely to have a Material Adverse
Effect. The Borrower and the Guarantors do not presently anticipate that future
expenditures needed to meet the provisions of any statutes, orders, rules or
regulations of a Governmental Authority will be so burdensome as to have a
Material Adverse Effect.

           (o) Financial Statements. The (i) Consolidated balance sheets of the
Borrower and its Subsidiaries as of December 31, 1997 and the related statements
of income and retained earnings and cash flows for the Fiscal Years then ended
and (ii) unaudited Consolidated balance sheet of the Borrower and its
Subsidiaries as of June 30, 1998 and related unaudited interim statements of
revenue and retained earnings, copies of which have been furnished to the
Administrative Agent and each Lender, are complete and correct in all material
respects, and fairly present the Consolidated financial condition of the
Borrower and its Subsidiaries as at such dates, and the results of the
operations and changes of financial position for the periods then ended. All
such financial statements, including the related schedules and notes thereto,
have been prepared in accordance with GAAP. The Borrower and its Subsidiaries
have no material Debt, obligation or other unusual forward or long-term
commitment which is not fairly reflected in the foregoing financial statements
or in the notes thereto.

           (p) No Material Adverse Change. Since December 31, 1997, there has
been no material adverse change in the properties, business, operations, or
condition (financial or otherwise) of the Borrower and its Subsidiaries and to
the knowledge of the Borrower no event has occurred or condition arisen that
could reasonably be expected to have a Material Adverse Effect.


                                       41
<PAGE>   48

           (q) Solvency. As of the Closing Date and after giving effect to each
Extension of Credit made hereunder, the Borrower and each of its Subsidiaries
will be Solvent.

           (r) Titles to Properties. Each of the Borrower and the Guarantors has
such title to the real property owned by it as is necessary or desirable to the
conduct of its business and valid and legal title to all of its personal
property and assets, including, but not limited to, those reflected on the
balance sheets of the Borrower and its Subsidiaries delivered pursuant to
Section 6.1(o), except those which have been disposed of by the Borrower or its
Subsidiaries subsequent to such date which dispositions have been in the
ordinary course of business or as otherwise expressly permitted hereunder.

           (s) Liens. None of the properties and assets of the Borrower or any
Guarantor thereof is subject to any Lien, except Liens permitted pursuant to
Section 10.3. No financing statement under the Uniform Commercial Code of any
state which names the Borrower or any Guarantor thereof or any of their
respective trade names or divisions as debtor and which has not been terminated,
has been filed in any state or other jurisdiction and neither the Borrower nor
any Subsidiary thereof has signed any such financing statement or any security
agreement authorizing any secured party thereunder to file any such financing
statement, except to perfect those Liens permitted by Section 10.3 hereof.

           (t) Debt and Guaranty Obligations. Schedule 6.1(t) is a complete and
correct listing of all Debt and Guaranty Obligations of the Borrower and its
Subsidiaries as of the Closing Date in excess of $10,000,000. The Borrower and
its Subsidiaries have performed and are in compliance with all of the terms of
such Debt and Guaranty Obligations and all instruments and agreements relating
thereto, and no default or event of default, or event or condition which with
notice or lapse of time or both would constitute such a default or event of
default on the part of the Borrower or its Subsidiaries exists with respect to
any such Debt or Guaranty Obligation.

           (u) Litigation. Except as set forth on Schedule 6.1(u), as of the
Closing Date there are no actions, suits or proceedings pending nor, to the
knowledge of the Borrower, threatened against the Borrower or any Guarantor or
any of their respective properties in any court or before any arbitrator of any
kind or before or by any Governmental Authority which, if adversely determined
could reasonably be expected to have a Material Adverse Effect.

           (v) Absence of Defaults. To the knowledge of the Borrower, no event
has occurred or is continuing which constitutes a Default or an Event of
Default, or which constitutes, or which with the passage of time or giving of
notice or both would constitute, a default or event of default by the Borrower
or any Guarantor thereof under any Material Contract or judgment, decree or
order to which the Borrower or any Guarantor is a party or by which the Borrower
or any Guarantor or any of their respective properties may be bound or which
would require the Borrower or any Guarantor to make any payment thereunder prior
to the scheduled maturity date therefor.

           (w) Accuracy and Completeness of Information. All written
information, reports and other papers and data produced by or on behalf of the
Borrower or any Subsidiary thereof and 



                                       42

recipient a true and accurate knowledge of the subject matter. No document
furnished or written statement made to the Administrative Agent or the Lenders
by the Borrower or any Subsidiary thereof in connection with the negotiation,
preparation or execution of this Agreement or any of the Loan Documents contains
or will contain any untrue statement of a fact material to the creditworthiness
of the Borrower or its Subsidiaries or omits or will omit to state a fact
necessary in order to make the statements contained therein not misleading. The
Borrower is not aware of any facts which it has not disclosed in writing to the
Administrative Agent having a Material Adverse Effect, or insofar as the
Borrower can now foresee, could reasonably be expected to have a Material
Adverse Effect.

           SECTION 6.2 Survival of Representations and Warranties, Etc. All
representations and warranties set forth in this Article VI and all
representations and warranties contained in any certificate, or any of the Loan
Documents (including but not limited to any such representation or warranty made
in or in connection with any amendment thereto) shall constitute representations
and warranties made under this Agreement. All representations and warranties

Agreement or any other Loan Document shall have been paid in full and the

delivery of this Agreement, any investigation made by or on behalf of the
Lenders or any borrowing hereunder.

part of the Administrative Agent or any Lender in exercising any right, power or
privilege shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any Event of Default. No course of dealing
between the Borrower, the Administrative Agent and the Lenders or their

received from the Borrower pursuant to any such tender or recovery in payment of
principal of and interest on the Obligations, promptly purchase the applicable
Permitted Currency at the most favorable spot exchange rate determined by the
Administrative Agent to be available to it. The obligation of the Borrower to
make payments in the applicable Permitted Currency shall be enforceable as an
alternative or additional cause of action solely for the purpose of recovering
in the applicable Permitted Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Permitted Currency expressed
to be payable pursuant to the applicable Loan Document.

for in, or received by the Administrative Agent under or in connection with,
this Agreement or the other Loan Documents or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
the other Loan Documents or for any failure of the Borrower or any of its
Subsidiaries to perform its obligations hereunder or thereunder. The
Administrative 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 to inspect the
properties, books or records of the Borrower or any of its Subsidiaries.

           SECTION 12.4 Reliance by the Administrative Agent. The Administrative

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 the

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

failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Notes.

           SECTION 12.5 Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless it has received notice from a Lender or the 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
Administrative Agent receives such a notice, it shall promptly give notice
thereof to the Lenders. The Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by
the Required Lenders; provided that unless and until the Administrative Agent

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, except to the extent that other provisions of
this Agreement expressly require that any such action be taken or not be taken

Lenders. Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact, Subsidiaries or Affiliates has made any representations or
warranties to it and that no act by the Administrative Agent hereinafter taken,
including any review of the affairs of the Borrower or any of its Subsidiaries,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
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 the Borrower and its Subsidiaries and made its own decision
to make its Loans and issue or participate in Letter of Credit hereunder and
enter into this Agreement. Each Lender also represents that it will,
independently and without reliance upon the Administrative 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 the Borrower and its Subsidiaries. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent hereunder or by the other Loan Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
property, financial and other condition or creditworthiness of the Borrower or
any of its Subsidiaries which may come into the possession of the Administrative
Agent or any of its respective officers, directors, employees, agents,
attorneys-in-fact, Subsidiaries or Affiliates.

           SECTION 12.7 Indemnification. The Lenders agree to indemnify the
Administrative Agent in its capacity as such and (to the extent not reimbursed
by the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to the respective amounts of their Commitment Percentages,
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 Notes or any Reimbursement Obligation) be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of this Agreement or 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
Administrative 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 Administrative
Agent's bad faith, gross negligence or willful misconduct. The agreements in
this Section 12.7 shall survive the payment of the Notes, any Reimbursement
Obligation and all other amounts payable hereunder and the termination of this
Agreement.

           SECTION 12.8 The Administrative Agent in Its Individual Capacity. The
Administrative Agent and its respective Subsidiaries and Affiliates may make
loans to, accept deposits from and generally engage in any kind of business with
the Borrower as though the Administrative Agent were not an Administrative Agent
hereunder. With respect to any Loans made or renewed by it and any Note issued
to it and with respect to any Letter of Credit issued by it or participated in
by it, the Administrative 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 an Administrative Agent, and the terms "Lender" and
"Lenders" shall include the Administrative Agent in its individual capacity.

           SECTION 12.9 Resignation of the Administrative Agent; Successor
Administrative Agent. Subject to the appointment and acceptance of a successor
as provided below, the Administrative Agent may resign at any time by giving
notice thereof to the Lenders and the Borrower. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Administrative
Agent, which successor shall have minimum capital and surplus of at least
$500,000,000. If no successor Administrative Agent shall have been so appointed
by the Required Lenders and shall have accepted such appointment within thirty
(30) days after the Administrative Agent's giving of notice of resignation, then
the Administrative Agent may, on behalf of the Lenders and with the consent of
the Borrower, appoint a successor Administrative Agent, which successor shall
have minimum capital and surplus of at least $500,000,000; provided that so long
as any Default or Event of Default exists or is continuing, the Borrower shall
have no consent rights pursuant to this Section 12.9. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. After any retiring Administrative
Agent's resignation hereunder as 



                                       62

Administrative Agent, the provisions of this Section 12.9 shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken by
it while it was acting as Administrative Agent.

sent by telecopy, (ii) on the next Business Day if sent by recognized overnight
courier service and (iii) on the third Business Day following the date sent by

out-of-pocket expenses of the Administrative Agent in connection with (i) the

connection therewith, which expenses shall include without limitation the

           SECTION 13.3 Set-off. In addition to any rights now or hereafter
granted under Applicable Law and not by way of limitation of any such rights,
upon and after the occurrence and during the continuation of any Event of
Default and upon the request of any Lender that the Administrative Agent declare
the Loans to be immediately due and payable or require cash collateral pursuant
to Section 11.2, the Lenders and any assignee or participant of a Lender in
accordance with Section 13.10 are hereby authorized by the Borrower at any time
or from time to time, without notice to the Borrower or to any other Person, any
such notice being hereby expressly waived, except as otherwise agreed in writing
by the Administrative Agent or the Lenders, to set off and to appropriate and to
apply any and all deposits (general or special, time or demand, including, but
not limited to, indebtedness evidenced by certificates of deposit, whether
matured or unmatured) and any other indebtedness at any time held or owing by
the Lenders, or any such assignee or participant to or for the credit or the
account of the Borrower against and on account of the Obligations irrespective
of whether or not the Administrative Agent shall have declared any or all of the
Obligations to be due and payable as permitted by Section 11.2 and although such
Obligations shall be contingent or unmatured.

           SECTION 13.4 Governing Law. This Agreement, the Notes and the other
Loan Documents, unless otherwise expressly set forth therein, shall be governed
by, construed and enforced in accordance with the laws of the State of North
Carolina, without reference to the conflicts or choice of law principles

consents to the personal jurisdiction of the state and federal courts located in
Mecklenburg County or Wake County, North Carolina, in any action, claim or other
proceeding arising out of any dispute in connection with this Agreement, the
Notes and the other Loan Documents, any rights or obligations hereunder or
thereunder, or the performance of such rights and obligations. The Borrower
hereby irrevocably consents to the service of a summons and complaint and other
process in any action, claim or proceeding brought by the Administrative Agent
or any Lender in connection with this Agreement, the Notes or the other Loan
Documents, any rights or obligations hereunder or thereunder, or the performance
of such rights and obligations, on behalf of itself or its property, in the
manner specified in Section 13.1. Nothing in this Section 13.5 shall affect the
right of the Administrative Agent or any Lender to serve legal process in any
other manner permitted by Applicable Law or affect the right of the
Administrative Agent or any Lender to bring any action or proceeding against the
Borrower or its properties in the courts of any other jurisdictions.

           SECTION 13.6 Binding Arbitration; Waiver of Jury Trial.

           (a) Binding Arbitration. Upon demand of any party, whether made
before or after institution of any judicial proceeding, any dispute, claim or
controversy arising out of, connected with or relating to the Notes or any other
Loan Documents ("Disputes"), between or among parties to the Notes or any other
Loan Document shall be resolved by binding arbitration as provided herein.
Institution of a judicial proceeding by a party does not waive the right of that
party to demand arbitration hereunder. Disputes may include, without limitation,
tort claims, counterclaims, claims brought as class actions, claims arising from
Loan Documents executed in the future, or 



                                       65
<PAGE>   72

claims concerning any aspect of the past, present or future relationships
arising out of or connected with the Loan Documents. Arbitration shall be
conducted under and governed by the Commercial Financial Disputes Arbitration
Rules (the "Arbitration Rules") of the American Arbitration Association and
Title 9 of the U.S. Code. All arbitration hearings shall be conducted in either
Charlotte or Raleigh, North Carolina. The expedited procedures set forth in Rule
51, et seq. of the Arbitration Rules shall be applicable to claims of less than
$1,000,000. All applicable statutes of limitation shall apply to any Dispute. A
judgment upon the award may be entered in any court having jurisdiction.
Notwithstanding anything foregoing to the contrary, any arbitration proceeding
demanded hereunder shall begin within ninety (90) days after such demand thereof
and shall be concluded within one-hundred twenty (120) days after such demand.
These time limitations may not be extended unless a party hereto shows cause for
extension and then such extension shall not exceed a total of sixty (60) days.
The panel from which all arbitrators are selected shall be comprised of licensed
attorneys. The single arbitrator selected for expedited procedure shall be a
retired judge from the highest court of general jurisdiction, state or federal,
of the state where the hearing will be conducted. The parties hereto do not
waive any applicable Federal or state substantive law except as provided herein.
Notwithstanding the foregoing, this paragraph shall not apply to any Hedging
Agreement that is a Loan Document.

           (b) Jury Trial. THE ADMINISTRATIVE AGENT, EACH LENDER AND THE
BORROWER HEREBY ACKNOWLEDGE THAT BY AGREEING TO BINDING ARBITRATION THEY HAVE
IRREVOCABLY WAIVED THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY
ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION WITH
THIS AGREEMENT, THE NOTES OR THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS
HEREUNDER OR THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

           (c) Preservation of Certain Remedies. Notwithstanding the preceding
binding arbitration provisions, the parties hereto and the other Loan Documents
preserve, without diminution, certain remedies that such Persons may employ or
exercise freely, either alone, in conjunction with or during a Dispute. Each
such Person shall have and hereby reserves the right to proceed in any court of
proper jurisdiction or by self help to exercise or prosecute the following
remedies: (i) all rights to foreclose against any real or personal property or
other security by exercising a power of sale granted in the Loan Documents or
under applicable law or by judicial foreclosure and sale, (ii) all rights of
self help including peaceful occupation of property and collection of rents, set
off, and peaceful possession of property, (iii) obtaining provisional or
ancillary remedies including injunctive relief, sequestration, garnishment,
attachment, appointment of receiver and in filing an involuntary bankruptcy
proceeding, and (iv) when applicable, a judgment by confession of judgment.
Preservation of these remedies does not limit the power of an arbitrator to
grant similar remedies that may be requested by a party in a Dispute.


                                       66

           SECTION 13.7 Reversal of Payments. To the extent the Borrower makes a
payment or payments to the Administrative Agent for the ratable benefit of the
Lenders or the Administrative Agent receives any payment or proceeds of the
collateral which payments or proceeds or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then, to
the extent of such payment or proceeds repaid, the Obligations or part thereof
intended to be satisfied shall be revived and continued in full force and effect
as if such payment or proceeds had not been received by the Administrative
Agent.

           SECTION 13.8 Injunctive Relief; Punitive Damages.

           (a) The Administrative Agent, Lenders and Borrower (on behalf of
itself and its Subsidiaries) hereby agree that no such Person shall have a
remedy of punitive or exemplary damages against any other party to a Loan
Document and each such Person hereby waives any right or claim to punitive or
exemplary damages that they may now have or may arise in the future in
connection with any Dispute, whether such Dispute is resolved through
arbitration or judicially.

           (b) The parties agree that they shall not have a remedy of punitive
or exemplary damages against any other party in any Dispute and hereby waive any
right or claim to punitive or exemplary damages they have now or which may arise
in the future in connection with any Dispute whether the Dispute is resolved by
arbitration or judicially.

           SECTION 13.9 Accounting Matters. All financial and accounting
calculations, measurements and computations made for any purpose relating to
this Agreement, including, without limitation, all computations utilized by the
Borrower or any Subsidiary thereof to determine compliance with any covenant
contained herein, shall, except as otherwise expressly contemplated hereby or
unless there is an express written direction by the Administrative Agent to the
contrary agreed to by the Borrower, be performed in accordance with GAAP as in
effect on the Closing Date. In the event that changes in GAAP shall be mandated
by the Financial Accounting Standards Board, or any similar accounting body of
comparable standing, or shall be recommended by the Borrower's certified public
accountants, to the extent that such changes would modify such accounting terms
or the interpretation or computation thereof, such changes shall be followed in
defining such accounting terms only from and after the date the Borrower and the
Lenders shall have amended this Agreement to the extent necessary to reflect any
such changes in the financial covenants and other terms and conditions of this
Agreement.

           SECTION 13.10 Successors and Assigns; Participations.

           (a) Benefit of Agreement. This Agreement shall be binding upon and
inure to the benefit of the Borrower, the Administrative Agent and the Lenders,
all future holders of the Notes, and their respective successors and assigns,
except that the Borrower shall not assign or transfer any of its rights or
obligations under this Agreement without the prior written consent of each
Lender.

           (b) Primary Syndication; Assignment by Lenders. The parties agree
that the Lenders who become party hereto pursuant to the primary syndication of
this Facility shall be Lenders who are mutually agreed upon by the
Administrative Agent and the Borrower. After the completion of the primary
syndication, each Lender may, with the consent of the Borrower (so long as no
Default or Event of Default has occurred and is continuing) and the consent of
the Administrative Agent, which consents shall not be unreasonably withheld,
assign to one or more Eligible Assignees all or a portion of its interests,
rights and obligations under this Agreement (including, without limitation, all
or a portion of the Extensions of Credit at the time owing to it and the Notes
held by it); provided that:

                      (i) each such assignment shall be of a constant, and not a
varying, percentage of all the assigning Lender's rights and obligations under
this Agreement;

                      (ii) if less than all of the assigning Lender's Commitment
is to be assigned, the Commitment so assigned shall not be less than
$10,000,000;

                      (iii) the parties to each such assignment shall execute
and deliver to the Administrative Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance in the form of Exhibit G attached hereto
(an "Assignment and Acceptance"), together with any Note or Notes subject to
such assignment;

                      (iv) such assignment shall not, without the consent of the
Borrower, require the Borrower to file a registration statement with the
Securities and Exchange Commission or apply to or qualify the Loans or the Notes
under the blue sky laws of any state; and

                      (v) the assigning Lender shall pay to the Administrative
Agent an assignment fee of $3,000 upon the execution by such Lender of the
Assignment and Acceptance; provided that no such fee shall be payable upon any
assignment by a Lender to an Affiliate thereof.

Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Assignment and Acceptance, which effective date
shall be at least five (5) Business Days after the execution thereof, (A) 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 hereby
and (B) the Lender thereunder shall, to the extent provided in such assignment,
be released from its obligations under this Agreement.

           (c) Rights and Duties Upon Assignment. By executing and delivering an
Assignment and Acceptance, the assigning Lender thereunder and the assignee
thereunder confirm to and agree with each other and the other parties hereto as
set forth in such Assignment and Acceptance.

           (d) Register. The Administrative Agent shall maintain a copy of each
Assignment and Acceptance delivered to it and a register for the recordation of
the names and addresses of the Lenders and the amount of the Extensions of
Credit with respect to each Lender from time to time (the "Register"). The
entries in the Register shall be conclusive, in the absence of manifest error,



                                       68
<PAGE>   75

and the Borrower, the Administrative Agent and the Lenders may treat each person
whose name is recorded in the Register as a Lender hereunder for all purposes of
this Agreement. The Register shall be available for inspection by the Borrower
or Lender at any reasonable time and from time to time upon reasonable prior
notice.

           (e) Issuance of New Notes. Upon its receipt of an Assignment and
Acceptance executed by an assigning Lender and an Eligible Assignee together
with any Note or Notes subject to such assignment and the written consent to
such assignment, the Administrative Agent shall, if such Assignment and
Acceptance has been completed and is substantially in the form of Exhibit G:

                      (i) accept such Assignment and Acceptance;

                      (ii) record the information contained therein in the
Register;

                      (iii) give prompt notice thereof to the Lenders and the
Borrower; and

                      (iv) promptly deliver a copy of such Assignment and
Acceptance to the Borrower.

Within five (5) Business Days after receipt of notice, the Borrower shall
execute and deliver to the Administrative Agent, in exchange for the surrendered
Note or Notes, a new Note or Notes to the order of such Eligible Assignee in
amounts equal to the Commitment assumed by it pursuant to such Assignment and
Acceptance and a new Note or Notes to the order of the assigning Lender in an
amount equal to the Commitment retained by it hereunder. Such new Note or Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Note or Notes, shall be dated the effective date of
such Assignment and Acceptance and shall otherwise be in substantially the form
of the assigned Notes delivered to the assigning Lender. Each surrendered Note
or Notes shall be canceled and returned to the Borrower.

           (f) Participations. Each Lender may sell participations to one or
more banks or other entities in all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Extensions of Credit and the Notes held by it); provided that:

                      (i) each such participation shall be in an amount not less
than $10,000,000;

                      (ii) such Lender's obligations under this Agreement
(including, without limitation, its Commitment) shall remain unchanged;

                      (iii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations;

                      (iv) such Lender shall remain the holder of the Notes held
by it for all purposes of this Agreement;


                                       69
<PAGE>   76

                      (v) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement;

                      (vi) such Lender shall not permit such participant the
right to approve any waivers, amendments or other modifications to this
Agreement or any other Loan Document other than waivers, amendments or
modifications which would reduce the principal of or the interest rate on any
Loan or Reimbursement Obligation, extend the term or increase the amount of the
Commitment, reduce the amount of any fees to which such participant is entitled,
extend any scheduled payment date for principal of any Loan or, except as
expressly contemplated hereby or thereby, release substantially all of the
Collateral; and

                      (vii) any such disposition shall not, without the consent
of the Borrower, require the Borrower to file a registration statement with the
Securities and Exchange Commission to apply to qualify the Loans or the Notes
under the blue sky law of any state.

           (g) Disclosure of Information; Confidentiality. The Administrative
Agent and the Lenders shall hold all non-public information with respect to the
Borrower obtained pursuant to the Loan Documents confidential in accordance with
their customary procedures for handling confidential information; provided, that
the Administrative Agent may disclose information relating to this Agreement to
Gold Sheets and other similar bank trade publications, such information to
consist of deal terms and other information customarily found in such
publications and approved by Borrower in writing prior to submission and
provided further, that the Administrative Agent and Lenders may disclose any
such information to the extent such disclosure is required by law or requested
by any regulatory authority. Any Lender may, in connection with any assignment,
proposed assignment, participation or proposed participation pursuant to this
Section 13.10, disclose to the assignee, participant, proposed assignee or
proposed participant, any information relating to the Borrower furnished to such
Lender by or on behalf of the Borrower; provided, that prior to any such
disclosure, each such assignee, proposed assignee, participant or proposed
participant shall agree with the Borrower or such Lender to preserve the
confidentiality of any confidential information relating to the Borrower
received from such Lender.

           (h) Certain Pledges or Assignments. Nothing herein shall prohibit any
Lender from pledging or assigning any Note to any Federal Reserve Bank in
accordance with Applicable Law.

           (i) Replacement of Lenders. If any Lender shall make any demand for
payment under Section 4.10, 4.12 or 4.13, or if any Lender shall be the subject
of any notification or assertion of a regulatory limitation under Section 4.9,
then within thirty (30) days after any such demand or notification or assertion,
the Borrower may, with the approval of the Administrative Agent (which approval
shall not be unreasonably withheld) and provided that no Event of Default or
Default shall then have occurred and be continuing, demand that such Lender
assign in accordance with this Section 13.10 to one or more assignees designated

Required Lenders, the Lender making a demand for payment or subject to a
notification or assertion of regulatory limitation shall not be included in the
Lender's holding Loans or having Commitments) all (but not less than all) of
such Lender's Commitment and the Loans owing and Reimbursement Obligations owing
to it within the period ending on the later to occur of such thirtieth (30th)
day and the last day of the longest of the then current Interest Periods for
such Loans. If any such assignee designated by the Borrower and approved by the
Required Lenders shall fail to consummate such assignment on terms acceptable to
such Lender, or if the Borrower shall fail to designate any such assignees
acceptable to the Required Lenders for all or part of such Lender's Commitment
or Extensions of Credit, then such demand by the Borrower shall become
ineffective; it being understood for purposes of this subsection (i) that such
assignment shall be conclusively deemed to be on terms acceptable to such
Lender, and such Lender shall be compelled to consummate such assignment to an
Eligible Assignee designated by the Borrower, if such Eligible Assignee (A)
shall agree to such assignment by entering into an Assignment and Acceptance
with such Lender and (B) shall offer compensation to such Lender in an amount
equal to all amounts then owing by the Borrower to such Lender hereunder and
under the Note made by the Borrower to such Lender, whether for principal,
interest, fees, costs or expenses (other than the demanded payment referred to
above and payable by the Borrower as a condition to the Borrower's right to
demand such assignment), or otherwise. In addition, in the event that the
Borrower shall be entitled to demand the replacement of any Lender pursuant to
this subsection (i), the Borrower may, in the case of any such Lender, with the
approval of the Administrative Agent (which approval shall not be unreasonably
withheld) and provided that no Event of Default or event that, with the giving
of notice or lapse of time or both, would constitute an Event of Default, shall
then have occurred and be continuing, terminate all (but not less than all) such
Lender's Commitment and prepay all (but not less than all) such Lender's
Extensions of Credit not so assigned, together with all interest accrued thereon
to the date of such prepayment and all fees, costs and expenses and other
amounts then owing by the Borrower to such Lender hereunder and under the Note
made by the Borrower to such Lender, at any time from and after such later
occurring day in accordance with Sections 2.3 and 2.5 hereof (but without any
requirement for ratable treatment of the other Lenders), if and only if, after
giving effect to such termination and prepayment, the sum of the aggregate
principal amount of the Extensions of Credit of all Lenders then outstanding
does not exceed the then remaining Aggregate Commitments of the Lenders.

           SECTION 13.11 Amendments, Waivers and Consents. Except as set forth
below, any term, covenant, agreement or condition of this Agreement or any of
the other Loan Documents (other than any Hedging Agreement, the terms and
conditions of which may be amended, modified or waived by the parties thereto)
may be amended or waived by the Lenders, and any consent given by the Lenders,
if, but only if, such amendment, waiver or consent is in writing signed by the
Required Lenders (or by the Administrative Agent with the consent of the
Required Lenders) and delivered to the Administrative Agent and, in the case of
an amendment, signed by the Borrower; provided, that no amendment, waiver or
consent shall (a) increase the amount or extend the time of the obligation of
the Lenders to make Loans or issue or participate in Letters of Credit
(including without limitation pursuant to Section 2.6), (b) extend the
originally scheduled time or times of payment of the principal of any Loan or
Reimbursement Obligation or the time or times of payment of interest on any Loan
or Reimbursement Obligation, (c) reduce the rate of interest or fees payable 



                                       71
<PAGE>   78

on any Loan or Reimbursement Obligation, (d) reduce the principal amount of any
Loan or Reimbursement Obligation, (e) permit any subordination of the principal
or interest on any Loan or Reimbursement Obligation, (f) amend the definition of
Alternative Currency, or (g) amend the provisions of this Section 13.11 or the
definition of Required Lenders, without the prior written consent of each
Lender. In addition, no amendment, waiver or consent to the provisions of (a)
Article XII shall be made without the written consent of the Administrative
Agent and (b) Article III without the written consent of the Issuing Lender.

           SECTION 13.12 Performance of Duties. The Borrower's obligations under
this Agreement and each of the Loan Documents shall be performed by the Borrower
at its sole cost and expense.

           SECTION 13.13 All Powers Coupled with Interest. All powers of
attorney and other authorizations granted to the Lenders, the Administrative
Agent and any Persons designated by the Administrative Agent or any Lender
pursuant to any provisions of this Agreement or any of the other Loan Documents
shall be deemed coupled with an interest and shall be irrevocable so long as any
of the Obligations remain unpaid or unsatisfied or the Credit Facility has not
been terminated.

           SECTION 13.14 Survival of Indemnities. Notwithstanding any
termination of this Agreement, the indemnities to which the Administrative Agent
and the Lenders are entitled under the provisions of this Article XIII and any
other provision of this Agreement and the Loan Documents shall continue in full
force and effect and shall protect the Administrative Agent and the Lenders
against events arising after such termination as well as before.

           SECTION 13.15 Titles and Captions. Titles and captions of Articles,
Sections and subsections in this Agreement are for convenience only, and neither
limit nor amplify the provisions of this Agreement.

           SECTION 13.16 Severability of Provisions. Any provision of this
Agreement or any other Loan Document which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective only to the extent
of such prohibition or unenforceability without invalidating the remainder of
such provision or the remaining provisions hereof or thereof or affecting the
validity or enforceability of such provision in any other jurisdiction.

           SECTION 13.17 Counterparts. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and shall be
binding upon all parties, their successors and assigns, and all of which taken
together shall constitute one and the same agreement.

           SECTION 13.18 Term of Agreement. This Agreement shall remain in
effect from the Closing Date through and including the date upon which all
Obligations shall have been indefeasibly and irrevocably paid and satisfied in
full. No termination of this Agreement shall affect the rights and obligations
of the parties hereto arising prior to such termination.

<PAGE>   113

                        UNCONDITIONAL GUARANTY AGREEMENT



           THIS UNCONDITIONAL GUARANTY AGREEMENT (this "Guaranty"), dated as of
the 7th day of August, 1998, made by each of the Guarantors listed on the
signature pages hereto or becoming a party hereto (the "Guarantors"), in favor
of FIRST UNION NATIONAL BANK, a national banking association, as Administrative
Agent (the "Administrative Agent"), for the ratable benefit of itself and the
financial institutions (the "Lenders") that are, or may from time to time
become, parties to the Credit Agreement (as hereinafter defined).

                              STATEMENT OF PURPOSE

           Pursuant to the terms of the Credit Agreement dated as of August 7,
1998 by and among Quintiles Transnational Corp. (the "Borrower"), the Lenders
party thereto, and the Administrative Agent (as amended, restated, supplemented
or otherwise modified from time to time, the "Credit Agreement"), the Lenders
extended certain credit facilities to the Borrower as more particularly
described therein. The Borrower and the Guarantors comprise one integrated
financial enterprise and all Extensions of Credit to the Borrower pursuant to
the Credit Agreement will inure, directly or indirectly, to the benefit of each
of the Guarantors.

           In connection with the transactions contemplated by the Credit
Agreement, the Lenders have requested, and each of the Guarantors has agreed to
execute and deliver, this Guaranty.

           NOW, THEREFORE, in consideration of the premises and the mutual
agreements set forth herein, and to induce the Lenders to make available
Extensions of Credit to the Borrower pursuant to the Credit Agreement, it is
agreed as follows:

           SECTION 1. Definitions. Capitalized terms used herein (including the
preamble hereof) shall have the meanings assigned to them in the Credit
Agreement, unless the context otherwise requires or unless otherwise defined
herein. References in the Credit Agreement to a "Guaranty Agreement" or herein
to this "Guaranty" shall include and mean this Guaranty, including all
amendments and supplements hereto now or hereafter in effect.

           SECTION 2. Guaranty of Obligations of the Borrower. Each Guarantor
hereby, jointly and severally with each other Guarantor, unconditionally,
absolutely and irrevocably guarantees to the Administrative Agent for the
ratable benefit of the Administrative Agent and the Lenders, and their
respective successors, endorsees, transferees and assigns, the prompt payment
(whether at stated maturity, by acceleration or otherwise) and performance of
all Obligations of the Borrower, whether primary or secondary (whether by way of
endorsement or otherwise), whether now existing or hereafter arising, whether or
not from time to time reduced or extinguished (except by payment thereof) or
hereafter increased or incurred, whether or not recovery may be or hereafter
become barred by the statute of limitations, whether enforceable or
unenforceable as against the Borrower, whether or not discharged, stayed or
otherwise affected by any bankruptcy, insolvency or other similar law or
proceeding, whether created directly with the Administrative Agent or any Lender
or acquired by the Administrative Agent or any Lender through assignment,
endorsement or otherwise, whether matured or unmatured, whether joint or
several, as and when the same become due and

<PAGE>   114

payable (whether at maturity or earlier, by reason of acceleration, mandatory
repayment or otherwise), in accordance with the terms of any such instruments
evidencing any such obligations, including all renewals, extensions or
modifications thereof (all Obligations of the Borrower to the Administrative
Agent or any Lender, including all of the foregoing, being hereinafter
collectively referred to as the "Guaranteed Obligations"); provided, that
notwithstanding anything to the contrary contained herein, it is the intention
of the Guarantors and the Lenders that, in any proceeding involving the
bankruptcy, reorganization, arrangement, adjustment of debts, relief of debtors,
dissolution or insolvency or any similar proceeding with respect to any
Guarantor or its assets, the amount of such Guarantor's obligations with respect
to the Obligations shall be in, but not in excess of, the maximum amount thereof
not subject to avoidance or recovery by operation of applicable law governing
bankruptcy, reorganization, arrangement, adjustment of debts, relief of debtors,
dissolution, insolvency, fraudulent transfers or conveyances or other similar
laws (including, without limitation, 11 U.S.C. ss.547, ss.548 and ss.550 and
other "avoidance" provisions of Title 11 of the United States Code), applicable
in any such proceeding to such Guarantor and this Guaranty (collectively,
"Applicable Insolvency Laws"). To that end, but only in the event and to the
extent that such Guarantor's obligations with respect to the Guaranteed
Obligations or any payment made pursuant to the Guaranteed Obligations would,
but for the operation of the foregoing proviso, be subject to avoidance or
recovery in any such proceeding under Applicable Insolvency Laws, the amount of
such Guarantor's obligations with respect to the Guaranteed Obligations shall be
limited to the largest amount which, after giving effect thereto, would not,
under Applicable Insolvency Laws, render such Guarantor's obligations with
respect to such Guaranteed Obligations unenforceable or avoidable or otherwise
subject to recovery under Applicable Insolvency Laws. To the extent any payment
actually made pursuant to the Guaranteed Obligations exceeds the limitation of
the foregoing proviso and is otherwise subject to avoidance and recovery in any
such proceeding under Applicable Insolvency Laws, the amount subject to
avoidance shall in all events be limited to the amount by which such actual
payment exceeds such limitation and the Guaranteed Obligations as limited by the
foregoing proviso shall in all events remain in full force and effect and be
fully enforceable against such Guarantor. The foregoing proviso is intended
solely to preserve the rights of the Administrative Agent hereunder against such
Guarantor in such proceeding to the maximum extent permitted by Applicable
Insolvency Laws and neither such Guarantor, the Borrower, any other Guarantor
nor any other Person shall have any right or claim under such proviso that would
not otherwise be available under Applicable Insolvency Laws in such proceeding.

           SECTION 3. Nature of Guaranty. Each Guarantor agrees that this
Guaranty is a continuing, unconditional, absolute and irrevocable guaranty of
payment and performance and not of collection, and that its obligations under
this Guaranty shall be primary, absolute and unconditional, irrespective of, and
unaffected by:

                     (a) the genuineness, validity, regularity, enforceability
           or any future amendment of, or change in, the Credit Agreement or any
           other Loan Document or any other agreement, document or instrument to
           which the Borrower or any Subsidiary thereof is or may become a
           party;

                     (b) any structural change in, restructuring of or other
           similar change of the Borrower or any of its Subsidiaries (including,
           without limitation, each Guarantor);

                                       2
<PAGE>   115

                     (c) the absence of any action to enforce this Guaranty, the
           Credit Agreement or any other Loan Document or the waiver or consent
           by the Administrative Agent or any Lender with respect to any of the
           provisions of this Guaranty, the Credit Agreement or any other Loan
           Document;

                     (d) the existence, value or condition of, or failure to
           perfect its Lien against, any security for or other guaranty of the
           Guaranteed Obligations or any action, or the absence of any action,
           by the Administrative Agent or any Lender in respect of such security
           or guaranty (including, without limitation, the release of any such
           security or guaranty); or

                     (e) any other action or circumstances which might otherwise
           constitute a legal or equitable discharge or defense of a surety or
           guarantor;

it being agreed by each Guarantor that, subject to the proviso in Section 2, its
obligations under this Guaranty shall not be discharged until the final and
indefeasible payment and performance, in full, of the Guaranteed Obligations and
the termination of the Commitments. Each Guarantor expressly waives all rights
it may now or in the future have under any statute (including without limitation
North Carolina General Statutes Section 26-7, et seq. or similar law) or at law
or in equity, or otherwise, to compel the Administrative Agent or any Lender to
proceed in respect of the Guaranteed Obligations against the Borrower or any
other party or against any security for or other guaranty of the payment and
performance of the Guaranteed Obligations before proceeding against, or as a
condition to proceeding against, such Guarantor; provided, however, that
regardless of any other provision of this Section 3, neither the Administrative
Agent nor any Lender shall proceed against any Guarantor hereunder until the
occurrence of an Event of Default. Each Guarantor further expressly waives and
agrees not to assert or take advantage of any defense based upon the failure of
the Administrative Agent or any Lender to commence an action in respect of the
Guaranteed Obligations against the Borrower, any Guarantor, any other guarantor
or any other party or any security for the payment and performance of the
Guaranteed Obligations. Each Guarantor agrees that any notice or directive given
at any time to the Administrative Agent or any Lender which is inconsistent with
the waivers in the preceding two sentences shall be null and void and may be
ignored by the Administrative Agent or such Lender, and, in addition, may not be
pleaded or introduced as evidence in any litigation relating to this Guaranty
for the reason that such pleading or introduction would be at variance with the
written terms of this Guaranty, unless the Administrative Agent and the Required
Lenders have specifically agreed otherwise in writing. The foregoing waivers are
of the essence of the transaction contemplated by the Loan Documents and, but
for this Guaranty and such waivers, the Administrative Agent and Lenders would
decline to enter into the Credit Agreement.

           SECTION 4. Demand by the Administrative Agent. In addition to the
terms set forth in Section 3, and in no manner imposing any limitation on such
terms, if all or any portion of the then outstanding Guaranteed Obligations are
declared to be or become immediately due and payable, then the Guarantors shall,
upon demand in writing therefor by the Administrative Agent to the Guarantors,
pay all or such portion of the outstanding Guaranteed Obligations then due and
payable. Payment by the Guarantors shall be made to the Administrative Agent, to
be credited and applied upon the Guaranteed Obligations, in immediately
available federal funds to an account designated by the Administrative Agent or
at the address referenced herein for the giving of notice to the 



                                       3

Administrative Agent or at any other address that may be specified in writing
from time to time by the Administrative Agent.

           SECTION 5. Waivers. In addition to the waivers contained in Section
3, each Guarantor waives and agrees that it shall not at any time insist upon,
plead or in any manner whatever claim or take the benefit or advantage of any
appraisal, valuation, stay, extension, marshalling of assets or redemption laws,
or exemption, whether now or at any time hereafter in force, which may delay,
prevent or otherwise affect the performance by such Guarantor of its obligations
under, or the enforcement by the Administrative Agent or the Lenders of, this
Guaranty. Each Guarantor further hereby waives diligence, presentment, demand,
protest and notice of whatever kind or nature with respect to any of the
Guaranteed Obligations and waives the benefit of all provisions of law which are
or might be in conflict with the terms of this Guaranty. Each Guarantor
represents, warrants and agrees that its obligations under this Guaranty are not
and shall not be subject to any counterclaims, offsets or defenses of any kind
against the Administrative Agent, the Lenders or the Borrower whether now
existing or which may arise in the future.

           SECTION 6. Benefits of Guaranty. The provisions of this Guaranty are
for the benefit of the Administrative Agent and the Lenders and their respective
successors, transferees, endorsees and assigns, and nothing herein contained
shall impair, as between the Borrower, the Administrative Agent and the Lenders,
the obligations of the Borrower under the Loan Documents. In the event all or
any part of the Guaranteed Obligations are transferred, endorsed or assigned by
the Administrative Agent or any Lender to any Person or Persons, any reference
to an "Administrative Agent", or "Lender" herein shall be deemed to refer
equally to such Person or Persons.

           SECTION 7. Modification of Loan Documents etc. If the Administrative
Agent or the Lenders shall at any time or from time to time, with or without the
consent of, or notice to, any Guarantor:

                     (a) change or extend the manner, place or terms of payment
           of, or renew or alter all or any portion of, the Guaranteed
           Obligations;

                     (b) take any action under or in respect of the Loan
           Documents in the exercise of any remedy, power or privilege contained
           therein or available to it at law or in equity, or waive or refrain
           from exercising any such remedies, powers or privileges;

                     (c) amend or modify, in any manner whatsoever, the Loan
           Documents;

                     (d) extend or waive the time for performance by any
           Guarantor, any other guarantor, the Borrower or any other Person of,
           or compliance with, any term, covenant or agreement on its part to be
           performed or observed under a Loan Document (other than this
           Guaranty), or waive such performance or compliance or consent to a
           failure of, or departure from, such performance or compliance;

                     (e) take and hold security or collateral for the payment of
           the Guaranteed Obligations or sell, exchange, release, dispose of, or
           otherwise deal with, any property pledged, mortgaged or conveyed, or
           in which the Administrative Agent or the Lenders have 



                                       4
<PAGE>   117

           been granted a Lien, to secure any Debt of any Guarantor, any other
           guarantor or the Borrower to the Administrative Agent or the Lenders;

                     (f) release anyone who may be liable in any manner for the
           payment of any amounts owed by any Guarantor, any other guarantor or
           the Borrower to the Administrative Agent or any Lender;

                     (g) modify or terminate the terms of any intercreditor or
           subordination agreement pursuant to which claims of other creditors
           of any Guarantor, any other guarantor or the Borrower are
           subordinated to the claims of the Administrative Agent or any Lender;
           or

                     (h) apply any sums by whomever paid or however realized to
           any amounts owing by any Guarantor, any other guarantor or the
           Borrower to the Administrative Agent or any Lender in such manner as
           the Administrative Agent or any Lender shall determine in its
           reasonable discretion;

then neither the Administrative Agent nor any Lender shall incur any liability
to any Guarantor as a result thereof, and no such action shall impair or release
the obligations of any Guarantor under this Guaranty.

           SECTION 8. Reinstatement. Each Guarantor agrees that, if any payment
made by the Borrower or any other Person applied to the Obligations is at any
time annulled, set aside, rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be refunded or repaid or the proceeds of
any collateral are required to be refunded by the Administrative Agent or any
Lender to the Borrower, its estate, trustee, receiver or any other party,
including, without limitation, any Guarantor, under any Applicable Law or
equitable cause, then, to the extent of such payment or repayment, each
Guarantor's liability hereunder (and any Lien securing such liability) shall be
and remain in full force and effect, as fully as if such payment had never been
made, and, if prior thereto, this Guaranty shall have been canceled or
surrendered (and if any Lien or collateral securing such Guarantor's liability
hereunder shall have been released or terminated by virtue of such cancellation
or surrender), this Guaranty (and such Lien) shall be reinstated in full force
and effect, and such prior cancellation or surrender shall not diminish,
release, discharge, impair or otherwise affect the obligations of such Guarantor
in respect of the amount of such payment (or any Lien securing such obligation).

           SECTION 9. Representations, Warranties and Covenants. To induce the
Lenders to execute the Credit Agreement and make any Extensions of Credit, each
Guarantor hereby represents, warrants, covenants and agrees on a joint and
several basis that:

                     (a) such Guarantor has the corporate right, power and
           authority to execute, deliver and perform this Guaranty and has taken
           all necessary corporate action to authorize its execution, delivery
           and performance of this Guaranty;

                     (b) this Guaranty constitutes the legal, valid and binding
           obligation of such Guarantor enforceable in accordance with its
           terms, except as enforceability may be limited by bankruptcy,
           insolvency, reorganization, moratorium, fraudulent 



                                       5
<PAGE>   118

           conveyance or similar laws affecting the enforcement of creditors'
           rights generally and by the availability of equitable remedies;

                     (c) the execution, delivery and performance of this
           Guaranty will not violate any provision of any Applicable Law or
           material contractual obligation of such Guarantor and will not result
           in the creation or imposition of any Lien upon or with respect to any
           property or revenues of such Guarantor;

                     (d) no consent or authorization of, filing with, or other
           act by or in respect of, any arbitrator or Governmental Authority and
           no consent of any other Person (including, without limitation, any
           stockholder or creditor of such Guarantor), is required in connection
           with the execution, delivery, performance, validity or enforceability
           of this Guaranty;

                     (e) no actions, suits or proceedings before any arbitrator
           or Governmental Authority are pending or, to the knowledge of such
           Guarantor, threatened by or against such Guarantor or against any of
           its properties with respect to this Guaranty or any of the
           transactions contemplated hereby;

                     (f) such Guarantor has such title to the real property
           owned by it and a valid leasehold interest in the real property
           leased by it, and has good and marketable title to all of its
           personal property sufficient to carry on its business free of any and
           all Liens of any type whatsoever, except those permitted by Section
           10.3 of the Credit Agreement;

                     (g) as of the Closing Date, such Guarantor (a) has capital
           sufficient to carry on its business and transactions and all business
           and transactions in which it engages and is able to pay its debts as
           they mature, (b) owns property having a fair value greater than the
           amount required to pay its probable liabilities (including
           contingencies) and (c) does not believe that it will incur debts or
           liabilities beyond its ability to pay such debts or liabilities as
           they mature;

                     (h) all payments under this Guaranty shall be made in the
           currency required by the Credit Agreement (the "Currency") in
           immediately available funds (and no obligation or liability of the
           Guarantors under this Guaranty shall be released or discharged by any
           judgment in a currency other than the Currency) unless any judgment
           or order of any court or other governmental department, commission,
           board, bureau, instrumentality or agency is given or made for the
           payment of any amount due under this Guaranty in a currency other
           than the Currency, in which event the Guarantors shall indemnify and
           hold harmless the Administrative Agent and the Lenders against any
           loss incurred by the Administrative Agent and the Lenders as a result
           of any such judgment or order and as a result of any variation having
           occurred in rates of exchange between the date of any such amount
           becoming due under this Guaranty and the date of actual payment
           thereof. The foregoing indemnity shall constitute a separate and
           independent obligation of the each Guarantor and shall continue in
           full force and effect notwithstanding any such judgment or order. The
           rate of exchange used 



                                       6
<PAGE>   119

           shall be that at which in accordance with normal banking procedures
           the Administrative Agent could purchase the Currency with the
           judgment currency on the Business Day succeeding that on which the
           final judgment is given; .

                     (i) all payments under this Guaranty shall be paid in full
           and made without set-off, counterclaim, condition or qualification,
           and free and clear of and without deduction or withholding for, or on
           account of, any present or future taxes, levies, imposts, duties,
           fees, assessments or other charges of any nature whatsoever, and all
           interest, penalties and similar liabilities with respect thereto
           (except such taxes, levies, imposts, duties, fees, assessments and
           other charges as are imposed on or measured by the Administrative
           Agent's or any Lender's net income by the country or any subdivision
           thereof in which the Administrative Agent's or any Lender's principal
           office or lending office is located or otherwise are in the nature of
           income taxes imposed on the Administrative Agent or any Lender),
           imposed, levied, collected, withheld or assessed by any taxing or
           other authority (all such non-excluded taxes, levies, imposts,
           duties, fees, assessments, charges, deductions, withholdings and
           liabilities, "Taxes"). If any Guarantor is compelled by law to deduct
           or otherwise account for any Taxes, each Guarantor shall (x) pay to
           the appropriate authority the amount of any and all such Taxes which
           such Guarantor is so compelled to make, prior to the date upon which
           any penalty may attach thereto, (y) pay in such manner, and at the
           same time as the payment of the amounts payable in accordance with
           clause (x), above, such additional amounts (if any) as may be
           necessary to ensure that the Administrative Agent and the Lenders
           receive a net amount equal to the full amount which the
           Administrative Agent and the Lenders would have received had the
           payment not been made subject to such Taxes, and (z) provide evidence
           that all applicable Taxes shall have been paid to the appropriate
           taxing authorities by delivery to the Administrative Agent, for the
           benefit of the Lenders, of official tax receipts or notarized copies
           within thirty (30) days after payment thereof, or if unobtainable due
           to governmental policy or inability, other acceptable evidence. Any
           Taxes which may become payable after payment in full of any amounts
           owed hereunder shall be paid by the Guarantors or reimbursed by the
           Guarantors if payment has been made by the Administrative Agent or
           any Lender, together with additional taxes, duties, fees and charges
           due as a consequence of such payment or reimbursement, and the
           Guarantors shall, as provided in clause (z), above, deliver to the
           Administrative Agent for the benefit of the Lenders appropriate
           receipts or other evidence of such payment;

                     (j) such Guarantor shall pay, indemnify and hold harmless
           the Administrative Agent and the Lenders from all present and future
           claims or liabilities for any registration, stamp, documentary and
           other similar taxes, fees or charges, and any penalties and interest
           with respect thereto, which may be assessed, levied or collected by
           any applicable Governmental Authority or by any department, agency,
           state or political subdivision or taxing authority thereof or therein
           or in connection with the execution, issuance, delivery, filing,
           registration or enforcement of this Guaranty;



                                       7
<PAGE>   120

                     (k) such Guarantor is generally subject to suit, and
           neither it nor any of its properties or assets has any immunity from
           the jurisdiction of any court or from legal process (whether through
           service of process or notice of attachment prior to judgment,
           attachment in aid of execution, execution or otherwise) under any
           Applicable Law;

                     (l) there is no tax, duty, fee, assessment or other
           governmental charge, or any deduction or withholding, imposed by any
           applicable Governmental Authority (i) on or by virtue of the
           execution, delivery, acquisition, registration or enforcement of this
           Guaranty, or (ii) on any payment to be made by such Guarantor
           pursuant to this Guaranty;

                     (m) to ensure the enforceability or admissibility in
           evidence of this Guaranty, it is not necessary that this Guaranty be
           filed or recorded with any applicable Governmental Authority or that
           any stamp or similar tax be paid hereon or in respect hereof;

                     (n) such Guarantor hereby agrees that a final judgment in
           any proceeding brought in any of the courts referred to in Section
           12(i) shall be conclusive and binding upon each Guarantor and may be
           enforced in the courts of the United States of America, the State of
           North Carolina or any other courts to the jurisdiction of which such
           Guarantor is subject, by a suit upon judgment, provided that service
           of process is effected on such Guarantor in one of the manners
           specified in Section 12(i) or as otherwise permitted by law; and

                     (o) to the extent that such Guarantor has or hereafter may
           acquire any immunity from suit, jurisdiction of any court or any
           legal process (whether through attachment prior to judgment,
           attachment in aid of execution, execution of a judgment, or from any
           other legal process or remedy) with respect to itself or its
           property, such Guarantor hereby irrevocably waives such immunity in
           respect of the Guaranteed Obligations and its obligations hereunder.

           SECTION 10.  Remedies.

           (a) Upon the occurrence of any Event of Default, with the consent of
the Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, enforce against the Guarantors
their respective obligations and liabilities hereunder and exercise such other
rights and remedies as may be available to the Administrative Agent hereunder,
under the other Loan Documents or otherwise.

           (b) No right or remedy herein conferred upon the Administrative Agent
is intended to be exclusive of any other right or remedy contained herein or in
any other Loan Document or otherwise, and every such right or remedy contained
herein and therein or now or hereafter existing at law, or in equity, or by
statute, or otherwise shall be cumulative. The Required Lenders may instruct the
Administrative Agent to pursue, or refrain from pursuing, any remedy available
to the Administrative Agent at such times and in such order as the Required
Lenders shall determine, and the Required Lenders' election as to such remedies
shall not impair any remedies against any 



                                       8
<PAGE>   121

Guarantor not then exercised. In addition, any election of remedies which
results in the denial or impairment of the right of the Administrative Agent to
seek a deficiency judgment against the Borrower shall not impair any Guarantor's
obligation to pay the full amount of the Guaranteed Obligations.

           SECTION 11. No Subrogation. Notwithstanding any payment or payments
by any of the Guarantors hereunder, or any set-off or application of funds of
any of the Guarantors by the Administrative Agent or any Lender, or the receipt
of any amounts by the Administrative Agent or any Lender with respect to any of
the Guaranteed Obligations, none of the Guarantors shall be entitled to be
subrogated to any of the rights of the Administrative Agent or any Lender
against the Borrower or any of the other Guarantors or against any collateral
security held by the Administrative Agent or any Lender for the payment of the
Guaranteed Obligations nor shall any of the Guarantors seek any reimbursement
from the Borrower or any of the other Guarantors in respect of payments made by
such Guarantor in connection with the Guaranteed Obligations, until all amounts
owing to the Administrative Agent and the Lenders on account of the Guaranteed
Obligations are paid in full and the Commitments are terminated. If any amount
shall be paid to any Guarantor on account of such subrogation rights at any time
when all of the Guaranteed Obligations shall not have been paid in full, such
amount shall be held by such Guarantor in trust for the Administrative Agent,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Administrative Agent in the exact form
received by such Guarantor (duly endorsed by such Guarantor to the
Administrative Agent, if required) to be applied against the Guaranteed
Obligations, whether matured or unmatured, in such order as set forth in the
Credit Agreement.

           SECTION 12.  Miscellaneous.

           (a) Entire Agreement; Amendments. This Guaranty, together with the
other Loan Documents, constitutes the entire agreement between the parties with
respect to the subject matter hereof and supersedes all prior agreements with
respect to the subject matter hereof and may not be amended or supplemented
except by a writing signed by each Guarantor and the Administrative Agent,
consented to by such Lenders as required by Section 13.11 of the Credit
Agreement.

           (b) Headings. Titles and captions of sections and subsections in this
Guaranty are for convenience of reference only, and neither limit nor amplify
the provisions of this Guaranty.

           (c) Severability. In the event that any one or more of the provisions
contained in this Guaranty shall be determined to be invalid, illegal or
unenforceable in any respect for any reason, the validity, legality and
enforceability of any such provision or provisions in every other respect and
the remaining provisions of this Guaranty shall not be in any way impaired.

           (d) Notices. All notices and communications hereunder shall be given
in accordance with Section 13.1 of the Credit Agreement and, in the case of the
Guarantors, shall be addressed to them at the address of the Borrower as set
forth in Section 13.1 of the Credit Agreement.

           (e) Binding Effect. This Guaranty shall bind each Guarantor and shall
inure to the benefit of the Administrative Agent and the Lenders and their
respective successors and assigns. No Guarantor may assign this Guaranty or
delegate any of its duties hereunder, other than in 



                                       9
<PAGE>   122

connection with the merger of such Guarantor into such other Person as permitted
by Section 10.5 of the Credit Agreement, or with the prior consent of the
Administrative Agent and each of the Lenders.

           (f) Non-Waiver. The failure of the Administrative Agent or any Lender
to enforce any right or remedy hereunder, or promptly to enforce any such right
or remedy, shall not constitute a waiver thereof, nor give rise to any estoppel
against the Administrative Agent or any Lender, nor excuse any Guarantor from
its obligations hereunder. Any waiver of any such right or remedy by the Lenders
must be in writing and signed by the Required Lenders.

           (g) Termination. This Guaranty shall terminate and be of no further
force or effect on the earlier of (i) the date when the Guaranteed Obligations
have been indefeasibly paid in full and the Commitments terminated, and (ii)
with regard to any specific Guarantor, the date on which such Guarantor is
merged (or wound up or dissolved) into another Credit Party pursuant to Section
10.5 of the Credit Agreement or is otherwise permitted to assign or delegate its
duties hereunder pursuant to Section 12(e).

           (h) Governing Law. This Guaranty shall be governed by and construed
and enforced in accordance with the laws of the State of North Carolina, without
reference to the conflicts or choice of law principles thereof.

           (i) Consent to Jurisdiction. Each Guarantor hereby irrevocably
consents to the personal jurisdiction of the state and federal courts located in
Mecklenburg County or Wake County, North Carolina, in any action, claim or other
proceeding arising out of any dispute in connection with this Guaranty, any
rights or obligations hereunder, or the performance of such rights and
obligations. Each Guarantor hereby irrevocably consents to the service of a
summons and complaint and other process in any action, claim or proceeding
brought by the Administrative Agent or any Lender in connection with this
Guaranty, any rights or obligations hereunder, or the performance of such rights
and obligations, on behalf of itself or its property, in the manner referenced
in Section 12(d). Nothing in this Section 12(i) shall affect the right of the
Administrative Agent or any Lender to serve legal process in any other manner
permitted by Applicable Law or affect the right of the Administrative Agent or
any Lender to bring any action or proceeding against any Guarantor or its
properties in the courts of any other jurisdictions.

           (j)       Binding Arbitration; Waiver of Jury Trial.

                     (i) Binding Arbitration. Upon demand of any party, whether
           made before or after institution of any judicial proceeding, any
           dispute, claim or controversy arising out of, connected with or
           relating to this Guaranty or any other Loan Documents ("Disputes"),
           between or among parties to this Guaranty or any other Loan Document
           shall be resolved by binding arbitration as provided herein.
           Institution of a judicial proceeding by a party does not waive the
           right of that party to demand arbitration hereunder. Disputes may
           include, without limitation, tort claims, counterclaims, claims
           brought as class actions, claims arising from Loan Documents executed
           in the future, or claims concerning any aspect of the past, present
           or future relationships arising out or connected with the Loan
           Documents. Arbitration shall be conducted under and governed by the
           Commercial Financial Disputes Arbitration Rules (the "Arbitration
           Rules") of the American Arbitration Association and 



                                       10
<PAGE>   123

           Title 9 of the U.S. Code. All arbitration hearings shall be conducted
           in either Charlotte or Raleigh, North Carolina. The expedited
           procedures set forth in Rule 51, et seq. of the Arbitration Rules
           shall be applicable to claims of less than $1,000,000. All applicable
           statutes of limitation shall apply to any Dispute. A judgment upon
           the award may be entered in any court having jurisdiction.
           Notwithstanding anything foregoing to the contrary, any arbitration
           proceeding demanded hereunder shall begin within ninety (90) days
           after such demand thereof and shall be concluded within one hundred
           and twenty (120) days after such demand. These time limitations may
           not be extended unless a party hereto shows cause for extension and
           then such extension shall not exceed a total of sixty (60) days. The
           panel from which all arbitrators are selected shall be comprised of
           licensed attorneys. The single arbitrator selected for expedited
           procedure shall be a retired judge from the highest court of general
           jurisdiction, state or federal, of the state where the hearing will
           be conducted. The parties hereto do not waive any applicable federal
           or state substantive law except as provided herein. Notwithstanding
           the foregoing, this paragraph shall not apply to any Hedging
           Agreement that is a Loan Document.

                     (ii) Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE LAW,
           THE ADMINISTRATIVE AGENT, EACH LENDER AND EACH GUARANTOR HEREBY
           ACKNOWLEDGE THAT BY AGREEING TO BINDING ARBITRATION THEY HAVE
           IRREVOCABLY WAIVED THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH
           RESPECT TO ANY ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY
           DISPUTE IN CONNECTION WITH THIS GUARANTY OR THE OTHER LOAN DOCUMENTS,
           ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE
           OF SUCH RIGHTS AND OBLIGATIONS.

                     (iii) Preservation of Certain Remedies. Notwithstanding the
           preceding binding arbitration provisions, the parties hereto and to
           the other Loan Documents preserve, without diminution, certain
           remedies that such Persons may employ or exercise freely, either
           alone, in conjunction with or during a Dispute. Each such Person
           shall have and hereby reserves the right to proceed in any court of
           proper jurisdiction or by self help to exercise or prosecute the
           following remedies: (A) all rights to foreclose against any real or
           personal property or other security by exercising a power of sale
           granted in the Loan Documents or under applicable law or by judicial
           foreclosure and sale, (B) all rights of self help including peaceful
           occupation of property and collection of rents, set off, and peaceful
           possession of property, (C) obtaining provisional or ancillary
           remedies including injunctive relief, sequestration, garnishment,
           attachment, appointment of receiver and in filing an involuntary
           bankruptcy proceeding, and (D) when applicable, a judgment by
           confession of judgment. Preservation of these remedies does not limit
           the power of an arbitrator to grant similar remedies that may be
           requested by a party in a Dispute.

           (k) Limitation of Liability. Neither the Administrative Agent, the
Lenders nor any Affiliate thereof shall have any liability with respect to, and
each Guarantor hereby waives, releases and agrees not to sue upon, any claim for
any punitive or exemplary damages suffered by such Guarantor in connection with,
arising out of, or in any way related to this Guaranty and the other Loan
Documents, the transactions contemplated herein or therein, or any act, omission
or event occurring in connection herewith or therewith.

           (l) Expenses. Each Guarantor agrees that it will reimburse the
Administrative Agent and each Lender for all reasonable out-of-pocket expenses
(including reasonable attorneys' fees and expenses, which shall be based upon
standard hourly rates and not the presumed rates set forth in the N.C. Gen.
Stat. Section 6-21.2) incurred by the Administrative Agent or such Lender in
connection with the enforcement of the obligations of the Guarantors under this
Guaranty and any other Loan Documents and all reasonable out-of-pocket expenses
(including reasonable attorneys' fees and expenses) incurred by the
Administrative Agent in connection with the amendment or modification of this
Guaranty.

           (m) Indemnities. Each Guarantor agrees to hold the Administrative
Agent and the Lenders harmless from and against all losses suffered by the
Administrative Agent and the Lenders in connection with (i) the exercise by the
Administrative Agent or the Lenders of any right or remedy granted to them under
this Guaranty, (ii) any claim, and the prosecution or defense thereof, arising
out of or in any way connected with this Guaranty, and (iii) the collection or
enforcement of the Obligations, the Guaranteed Obligations or any of them;
provided, that such Guarantor shall not be obligated to reimburse the
Administrative Agent or the Lenders for costs and expenses, or indemnify the
Administrative Agent or the Lenders for any loss, resulting from the gross
negligence or willful misconduct of the Administrative Agent or the Lenders.
Notwithstanding any termination of this Guaranty, the indemnities to which the
Administrative Agent and Lenders are entitled under this Guaranty shall continue
in full force and effect and shall protect the Administrative Agent and the
Lenders against events arising after such termination as well as before.

           (n) Survival of Indemnities. Notwithstanding any termination of this
Guaranty or any other provisions of this Guaranty to the contrary, the
obligations of each Guarantor and the indemnities with respect thereto, to which
the Administrative Agent and the Lenders are entitled under Sections 12(l) and
(m) shall continue in full force and effect for the benefit of the
Administrative Agent and the Lenders notwithstanding the prior payment in full
of the Guaranteed Obligations and the termination of the Credit Agreement.
