                                    PART II
 
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's amended and restated Bylaws require the Company to indemnify
its directors, officers, employees and agents to the fullest extent permitted by
the Delaware General Corporation Law, including those circumstances in which
indemnification would otherwise be discretionary, except that the Company will
not be obligated to indemnify any such person (i) with respect to proceedings,
claims or actions initiated or brought voluntarily by any such person and not by
way of defense; (ii) for any amounts paid in settlement of an action indemnified
against by the Company without the proper written consent of the Company; or
(iii) in connection with any event in which the person did not act in good faith
and in a manner reasonably believed to be in, or not opposed to, the best
interests of the Company. In addition, the Company has entered or will enter
into Indemnity Agreements with each of its directors and officers providing for
indemnification of and advancement of expenses to the directors and officers to
the fullest extent permitted by law except (a) if and to the extent that payment
is made to the indemnitee under an insurance policy or otherwise; (b) if and to
the extent that a claim is decided adversely based on or attributable to the
indemnitee gaining any personal profit or advantage to which the indemnitee was
not legally entitled; (c) if and to the extent that the indemnifiable event
constituted or arose out of the indemnitee's willful misconduct or gross
negligence; or (d) if and to the extent that the proceeding is initiated by the
indemnitee against the Company of any of its officers or directors, unless the
Company has consented to or joined in the initiation of the proceeding. The
Delaware General Corporation Law contains an extensive indemnification provision
that permits a corporation to indemnify any person who is or was a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he or she is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.
 
     The Company's Second Restated Certificate eliminates the personal liability
of the directors of the Company to the Company or its stockholders for monetary
damages for breach of their duty of care except to the extent that such
exemption from liability or limitation thereof is not permitted under the
Delaware General Corporation Law. The Delaware General Corporation Law prohibits
a corporation from eliminating or limiting the liability of a director (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders; (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (iii) for liability under
Section 174 of the Delaware General Corporation Law (relating to certain
unlawful dividends, stock purchases or stock redemptions); or (iv) for any
transaction from which the director derived any improper personal benefit.

 (1) Incorporated by reference to the Registration Statement on Form S-1 of the
     Registrant (Registration No. 33-63448) filed May 27, 1993 and declared
     effective July 15, 1993.
 
 (b) Financial Statement Schedules
 
     Schedule II Valuation and Qualifying Accounts incorporated by reference to
the Registrant's Annual Report on Form 10-K for the fiscal year ended June 30,
1997.
 
     All other schedules have been omitted on the basis of immateriality or
because such schedules are not otherwise applicable.
 
ITEM 22.  UNDERTAKINGS
 
     (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (b) (1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     (2) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
 
                                      II-2
<PAGE>   8
 
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant, in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
     (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction that was not
the subject of and included in the registration statement when it became
effective.

                            REVOLVING CREDIT FACILITY

      SECTION 2.1 Loans. Subject to the terms and conditions of this Agreement,
each Lender severally agrees to make Loans to the Borrower from time to time
from the Closing Date through but not including the Termination Date as
requested by the Borrower in accordance with Section 2.2; provided, that (a) the
aggregate principal amount of all outstanding Loans (after giving effect to any
amount requested) shall not exceed the Aggregate Commitment less the L/C
Obligations and (b) the principal amount of Extensions of Credit from any Lender
to the Borrower shall not at any time exceed such Lender's Commitment. Each Loan
by a Lender shall be in a principal amount equal to such Lender's Commitment
Percentage of the aggregate principal amount of Loans requested on such
occasion. Subject to the terms and conditions hereof, the Borrower may borrow,
repay and reborrow Loans hereunder until the Termination Date.

      SECTION 2.2 Procedure for Advance of Loans.


      (a) Requests for Borrowing. The Borrower shall give the Agent irrevocable
prior written notice (or telephonic notice confirmed by written notice) in the
form attached hereto as Exhibit B (a "Notice of Borrowing") not later than 11:00
a.m. (Charlotte time) (i) on the same Business Day as each Base Rate Loan and
(ii) at least three Business Days before each LIBOR Rate Loan, of a proposed
borrowing specifying (A) the date of such borrowing, which shall be a Business
Day, (B) the amount of such borrowing, which shall be with respect to LIBOR Rate
Loans in an aggregate principal amount of $3,000,000 or a whole multiple of
$500,000 in excess thereof and with respect to Base Rate Loans in an aggregate
principal amount of $1,000,000 or a whole multiple of $500,000 in excess
thereof, (C) whether the Loans are to be LIBOR Rate Loans or Base Rate Loans,
and (D) in the case of a LIBOR Rate Loan, the duration of the Interest Period

deemed received on the next Business Day. The Agent shall promptly notify the
Lenders of each Notice of Borrowing.


                                       15
<PAGE>   22
      (b) Disbursement of Loans. Not later than 2:00 p.m. (Charlotte time) on
the proposed borrowing date, each Lender will make available to the Agent, for
the account of the Borrower, at the office of the Agent in funds immediately
available to the Agent, such Lender's Commitment Percentage of the Loans to be
made on such borrowing date. Promptly after the Agent's receipt of such funds
and upon fulfillment of the applicable conditions set forth in Article V, the
Agent will (and each Lender hereby irrevocably authorizes the Agent to) make
such funds available to the Borrower by crediting such proceeds to a deposit
account of the Borrower maintained with the Agent or by wire transfer to such
account as may be agreed upon by the Borrower and the Agent from time to time.
Subject to Section 4.5 hereof, the Agent shall not be obligated to disburse the
proceeds of any Loan requested pursuant to this Section 2.2 until each Lender
shall have made available to the 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, together with all accrued but
unpaid interest thereon, on the Termination Date.

      (b) Mandatory Repayment of Excess Loans. If at any time the outstanding
principal amount of all Extensions of Credit exceeds the Aggregate Commitment,
the Borrower shall repay the Extensions of Credit immediately by making first, a
payment of principal of the Loans to the Agent for the account of the Lenders
and second, with respect to any Letters of Credit then outstanding, the payment
of cash collateral into a cash collateral account opened by the Borrower with
the Agent for the benefit of the Lenders), in an aggregate amount equal to such
excess. Each such repayment shall be accompanied by accrued interest on the
amount repaid and any amount required to be paid pursuant to Section 4.7 hereof.

      (c) Optional Repayments. The Borrower may at any time and from time to
time repay the Loans, in whole or in part, upon irrevocable notice to the Agent
no later than 11:00 a.m., at least three (3) Business Days' prior to such
repayment with respect to LIBOR Rate Loans and on the same day of such repayment
with respect to Base Rate Loans, in the form attached hereto as Exhibit C (a
"Notice of Prepayment") specifying the date and amount of repayment and whether
the repayment is of LIBOR Rate Loans, Base Rate Loans, or a combination thereof,
and, if of a combination thereof, the amount allocable to each. Upon receipt of
such notice, the 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
$1,000,000 or a whole multiple of $500,000 in excess thereof with respect to
Base Rate Loans and $3,000,000 or a whole multiple of $500,000 in excess thereof
with respect to LIBOR Rate Loans. Each such repayment shall be accompanied by
any amount required to be paid pursuant to Section 4.7 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 4.7 hereof.


                                       16
<PAGE>   23
      SECTION 2.4 Notes. Each Lender's Loans and the obligation of the Borrower
to repay such Loans shall be evidenced by a 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 by such Lender to the Borrower hereunder, plus interest on
such principal amounts 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 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 Agent, to permanently reduce, in whole at any time or in part from time to
time, without premium or penalty, the Aggregate Commitment in an aggregate
principal amount not less than $5,000,000 or any integral multiple of $1,000,000
in excess thereof.

      (b) Payments. Each permanent reduction permitted pursuant to this Section
2.5 shall be accompanied by a payment of principal of the Loans (or with respect
to any Letters of Credit then outstanding, the payment of cash collateral into a
cash collateral account opened by the Borrower with the Agent for the benefit of
the Lenders) sufficient to reduce the Extensions of Credit to the Aggregate
Commitment, as so reduced, and by payment of accrued interest on the amount of
such repaid principal. Any reduction of the Aggregate Commitment to zero shall
be accompanied by payment of all outstanding Obligations (and funding of a cash
collateral account opened by the Borrower with the Agent for the benefit of the
Lenders in an amount equal to all Letters of Credit then outstanding) and
termination of the Aggregate Commitment and Credit Facility. Amounts on deposit
in the cash collateral account shall be applied in accordance with Section
11.2(b). If the reduction of the Aggregate Commitment requires the repayment of
any LIBOR Rate Loan, such reduction may be made only on the last day of the then
current Interest Period applicable thereto unless such repayment is accompanied
by any amount required to be paid pursuant to Section 4.7 hereof.

      SECTION 2.6 Termination of Credit Facility. The Credit Facility shall
terminate on the earliest of (a) March 16, 2003, (b) the date of permanent
reduction of the Aggregate Commitment in whole pursuant to Section 2.5, or (c)
the date of termination by the 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
Loans (a) to refinance certain existing Debt, (b) to pay certain fees and
expenses related to the transactions contemplated hereby, (c) to finance
Permitted Acquisitions and (d) to provide for the ongoing working capital
requirements of the Credit Parties.

<PAGE>   24
      SECTION 3.1 L/C Commitment.

      (a) Subject to the terms and conditions hereof, the Issuing Lender, in
reliance on the agreements of the other Lenders set forth in Section 3.3(a),
agrees to issue letters of credit (the "Letters of Credit") for the account of
the Borrower on a Business Day during the period from the Closing Date through
but not including the Termination Date in such form as may be reasonably
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, (i) the L/C Obligations would exceed Ten Million
Dollars ($10,000,000) or (ii) the total Extensions of Credit then outstanding
would exceed the Aggregate Commitment.

      (b) 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 the
obligations of any Borrower incurred in the ordinary course of its business,
(iii) expire on a date no later than the earlier of (A) one year from the
issuance thereof or (B) March 16, 2003 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 Letters 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.

      SECTION 3.2 Procedure for Issuance of Letters of Credit. The Borrower may
request that the Issuing Lender issue a Letter of Credit on behalf of the
Borrower or on behalf of any of its Subsidiaries; provided that for any Letter
of Credit issued on behalf of any of its Subsidiaries, the Borrower shall be the
applicant with the Subsidiary as the co-applicant by delivering to the Issuing
Lender at its address for notices specified herein 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 the Letter of Credit earlier than three
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. 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.

   
      SECTION 3.3 L/C Participations.
    


      (a) The Issuing Lender hereby grants to each L/C Participant, and, to
induce the Issuing Lender to issue the Letters of Credit hereunder, each L/C
Participant hereby accepts and purchases


                                       18
<PAGE>   25
from the Issuing Lender, on the terms and conditions hereinafter stated, for
such L/C Participant's own account and risk an undivided interest equal to such
L/C Participant's Commitment Percentage in the Issuing Lender's obligations and
rights under each Letter of Credit issued hereunder and the amount of each draft
paid by the Issuing Lender thereunder. Each L/C Participant unconditionally and
irrevocably agrees with the Issuing Lender that, if a draft is paid under any
Letter of Credit for which the Issuing Lender is not reimbursed in full by the
Borrower in accordance with the terms of this Agreement, such L/C Participant
shall pay to the Issuing Lender upon demand at the Issuing Lender's address for
notices specified herein an amount equal to such L/C Participant's Commitment
Percentage of the amount of such draft, or any part thereof, which is not so
reimbursed.

      (b) Upon becoming aware of any amount required to be paid by any L/C
Participant to the Issuing Lender pursuant to Section 3.3(a) in respect of any
unreimbursed portion of any payment made by the Issuing Lender under any Letter
of Credit, the Issuing Lender shall notify each L/C Participant of the amount
and due date of such required payment and such L/C Participant shall pay to the
Issuing Lender the amount specified on the applicable due date. If any such
amount is paid to the Issuing Lender after the date such payment is due, such
L/C Participant shall pay to the Issuing Lender on demand, in addition to such
amount, the product of (i) such amount, times (ii) the daily average Federal
Funds Rate as determined by the Agent during the period from and including the
date such payment is due to the date on which such payment is immediately
available to the Issuing Lender, times (iii) a fraction the numerator of which
is the number of days that elapse during such period and the denominator of
which is 360. With respect to payment to the Issuing Lender of the unreimbursed
amounts described in this Section 3.3(b), if the L/C Participants receive notice
that any such payment is due (A) prior to 2:00 p.m. (Charlotte time) on any
Business Day, such payment shall be due that Business Day, and (B) after 2:00
p.m. (Charlotte time) on any Business Day, such payment shall be due on the
following Business Day.

      (c) Whenever, at any time after the Issuing Lender has made payment under
any Letter of Credit and has received from any L/C Participant its Commitment
Percentage of such payment in accordance with this Section 3.3, the Issuing
Lender receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise), or any payment of interest on account thereof,
the Issuing Lender will distribute to such L/C Participant its pro rata share
thereof; provided, that in the event that any such payment received by the
Issuing Lender shall be required to be returned by the Issuing Lender, such L/C
Participant shall return to the Issuing Lender the portion thereof previously
distributed by the Issuing Lender to it.

      SECTION 3.4 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 such draft so paid and any taxes, reasonable
out-of-pocket 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 are paid by the Issuing Lender until payment in full at the rate per
annum equal to two percent (2%) in excess of the rate then applicable to Base
Rate Loans. The Issuing Lender shall notify the Borrower by facsimile promptly
of the presentment for payment of


                                       19
<PAGE>   26
any Letter of Credit by any beneficiary, together with notice of the date such
payment shall be made; provided, that the failure of the Issuing Lender to
provide such notice shall not limit or affect in any manner any of the
Borrower's obligations set forth herein.

      SECTION 3.5 Obligations Absolute. Except as described below, 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 any 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 3.4 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 (absent the gross negligence or willful misconduct of the Issuing
Lender), or any dispute between or among the Borrower and any beneficiary of a
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 the message or advice, however transmitted, in connection with a
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 Uniform Commercial Code as in effect in North Carolina, 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 3.6 Fees and Other Charges.


      (a) The Borrower shall pay to the Agent, for the account of the Issuing
Lender and the L/C Participants, a letter of credit fee with respect to each
Letter of Credit in an amount equal to the product of (i) the fraction that is
determined by dividing (A) the number of days that the Letter of Credit is to be
outstanding by (B) 360, (ii) the Applicable Margin with respect to LIBOR Rate
Loans and (iii) the face amount of such Letter of Credit. Such fee shall be
payable quarterly in arrears on the last Business Day of each calendar quarter
and on the Termination Date. The Agent shall, promptly following its receipt
thereof, distribute to the Issuing Lender and the L/C Participants all fees
received by the Agent pursuant to this paragraph (a) in accordance with their
respective Commitment Percentages.

      (b) The Borrower shall pay to the Issuing Lender for its own account a
letter of credit fee with respect to each Letter of Credit in an amount equal to
the product of (i) the fraction that is determined by dividing (A) the number of
days that the Letter of Credit is to be outstanding by (B)


                                       20
<PAGE>   27
360, (ii) 0.125% and (iii) the face amount of such Letter of Credit. Such fee
shall be payable quarterly in arrears on the last Business Day of each calendar
quarter and on the Termination Date.

                                   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, the principal balance of any Loan shall bear
interest at the Base Rate or LIBOR plus, in each case, the Applicable Margin as
set forth below. 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 Sections 2.2, or at the time a Notice of Conversion/
Continuation is given pursuant to Section 4.2. Each Loan bearing interest based
on the Base Rate shall be a "Base Rate Loan", and each Loan bearing interest
based on LIBOR shall be a "LIBOR Rate Loan". Any Loan as to which the Borrower
has not duly specified an interest rate as provided herein shall be deemed a
Base Rate Loan.

      (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, two or three months; provided
that:

            (i) each 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 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 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 calendar month at the end of such Interest Period;

            (iv) no Interest Period shall extend beyond the Termination Date and
no Interest Period shall be selected which would result in the repayment of any
LIBOR Rate Loan prior to the end of an Interest Period; and

            (v) there shall be no more than five (5) Interest Periods in effect
at any time.


                                       21
<PAGE>   28
      (c) Applicable Margin. The Applicable Margin provided for in Section
4.1(a) with respect to the Loans (the "Applicable Margin") shall be determined
by reference to the Total Debt Leverage Ratio as of the end of the fiscal
quarter immediately preceding the delivery of the applicable Officer's
Compliance Certificate in accordance with the following chart:

<TABLE>
<CAPTION>
      Total Debt                           Applicable Margin Per Annum
      Leverage Ratio                      Base Rate +       LIBOR Rate +

<S>                                       <C>               <C>
      Less than 2.00 to 1.00              0.00%             0.875%

      Greater than or equal to
      2.00 to 1.00
      and less than 2.50 to 1.00          0.00%             1.125%

      Greater than or equal to
      2.50 to 1.00
      and less than 3.00 to 1.00          0.00%             1.375%

      Greater than or equal to
      3.00 to 1.00
      and less than 3.50 to 1.00          0.125%            1.625%

      Greater than or equal to
      3.50 to 1.00                        0.250%            1.750%
</TABLE>

Adjustments, if any, in the Applicable Margin shall be made by the Agent on the
fifth (5th) day (or, if not a Business Day, on the next succeeding Business Day)
following receipt by the Agent of financial statements for the Borrower and its
Subsidiaries pursuant to Sections 7.1(a) and 7.1(b) and the accompanying
Officer's Compliance Certificate (such date, the "Adjustment Date"), setting
forth the Total Debt Leverage Ratio as of the most recent fiscal quarter end;
provided that no adjustment shall be made to decrease the Applicable Margin at
any time that a Default or Event of Default has occurred and is continuing. In
the event the Borrower fails to deliver such financial statements and the
accompanying Officer's Compliance Certificate within the time required by
Sections 7.1 and 7.2 hereof, the Applicable Margin shall be the highest
Applicable Margin set forth above until the Adjustment Date following delivery
of such financial statements and the accompanying Officer's Compliance
Certificate.

      (d) Default Rate. Upon the occurrence and during the continuance of an
Event of Default, (i) at the option of the Required Lenders, the Borrower shall
no longer have the option to request LIBOR Rate Loans, (ii) all amounts due and
payable with respect to 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, and (iii)
all amounts due and payable with respect to 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 a Borrower of any petition seeking any relief in


                                       22
<PAGE>   29
bankruptcy or under any act or law pertaining to insolvency or debtor relief,
whether state, federal or foreign.

      (e) Interest Payment and Computation. Interest on each Base Rate Loan
shall be payable in arrears on the last Business Day of each calendar quarter
commencing March 31, 1998, and interest on each LIBOR Rate Loan shall be payable
on the last day of each Interest Period applicable thereto. All accrued and
unpaid interest shall be paid in full on the Termination Date, together with any
amounts payable pursuant to Section 4.7. Interest rates based on the Base Rate
shall be computed on the basis of a 365-day year and assessed for the actual
number of days elapsed and all other interest rates, fees and commissions
provided hereunder shall be computed on the basis of a 360-day year and assessed
for the actual number of days elapsed.

      (f) Agreed Interest Rate. The Borrower agrees to pay an effective
contracted for rate of interest equal to the rate of interest resulting from all
interest payable as provided herein, plus any additional rate of interest
resulting from the Additional Sums. For the purposes of this provision, the
"Additional Sums" shall consist of all fees, charges, goods, things in action or
other sums or things of value (other than the interest resulting from the
interest provided herein) paid or payable by the Borrower, whether pursuant to
this Agreement, the Notes or any other Loan Document, that may be deemed to be
interest for the purpose of any Applicable Law that may limit the maximum amount
of interest to be charged with respect to the Extensions of Credit. The
Additional Sums shall be deemed to be additional interest only for the purposes
of any such Applicable Law.

      (g) Maximum Rate. In no contingency or event whatsoever shall the
aggregate of all amounts deemed interest hereunder or under 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 contracted for,
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 Agent's option promptly
refund to the Borrower any interest received by Lenders in excess of the maximum
lawful rate or 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 Agent nor any Lender charge, receive or contract to
receive, directly or indirectly in any manner whatsoever, interest in excess of
the maximum non-usurious rate that 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 convert at any time all or any portion of
their outstanding Base Rate Loans in a principal amount equal to $3,000,000 or
any whole multiple of $500,000 in excess thereof into one or more LIBOR Rate
Loans. Upon the expiration of any Interest Period, the Borrower may convert all
or any portion of their outstanding LIBOR Rate Loans into Base Rate Loans in a
principal amount equal to $1,000,000 or a whole multiple of $500,000 in excess
thereof or to continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the
Borrower desires to convert or continue Loans as provided above, the Borrower
shall give the Agent irrevocable prior written notice in the form attached as
Exhibit D(a "Notice of Conversion/Continuation") not later than 11:00 a.m.
(Charlotte time) three (3) Business Days, in the event of a conversion to or
continuation as LIBOR Rate Loans,


                                       23
<PAGE>   30
and one (1) Business Day, in the event of a conversion to Base Rate Loans,
before the day on which a proposed conversion or continuation of such Loan is to
be effective specifying (i) the Loans to be converted or continued, and, in the
case of a LIBOR Rate Loan to be converted or continued, the last day of the
Interest Period therefor, (ii) the effective date of such conversion or
continuation (which shall be a Business Day), (iii) the principal amount of such
Loans to be converted or continued, and (iv) the Interest Period to be
applicable to such converted or continued LIBOR Rate Loan. The Agent shall
promptly notify the Lenders of such Notice of Conversion/Continuation. If,
within the time period required under the terms of this Section 4.2, the Agent
does not receive a Notice of Conversion/Continuation from the Borrower
containing an election to continue LIBOR Rate Loans for an additional Interest
Period or to convert such LIBOR Rate Loans, then, upon the expiration of the
Interest Period therefor, such Loans will be automatically converted to Base
Rate Loans.

      SECTION 4.3 Commitment and Agency Fees.

      (a) Agent's Fee. In order to compensate the Agent for its obligations
hereunder, the Borrower agrees to pay to the Agent for its own account the fees
set forth in a separate letter agreement between the Agent and the Borrower
dated February 3, 1998.

      (b) Commitment Fee. Commencing on the Closing Date, the Borrower shall pay
to the Agent, for the account of the Lenders, a non-refundable commitment fee on
the average daily unused portion of the Aggregate Commitment, at a rate per
annum determined by reference to the Total Debt Leverage Ratio as of the end of
the fiscal quarter immediately preceding the delivery of the applicable
Officer's Compliance Certificate in accordance with the following chart:

<TABLE>
<CAPTION>
                  Total Debt Leverage Ratio           Commitment Fee Percentage
                  -------------------------           -------------------------
<S>                                                   <C>
                  Greater than or equal to
                  3.50 to 1.0.                          0.375%

                  Less than 3.50 to 1.0.                0.250%
</TABLE>

The commitment fee shall be payable in arrears on the last Business Day of each
calendar quarter during the term of this Agreement commencing March 31, 1998,
and on the Termination Date. Such commitment fee shall be distributed by the
Agent to the Lenders pro rata in accordance with the Lenders' respective
Commitment Percentages. Adjustments, if any, in the commitment fee shall be made
by the Agent on the fifth (5th) day (or, if not a Business Day, on the next
succeeding Business Day) following receipt by the Agent of financial statements
for the Borrower and its Subsidiaries pursuant to Sections 7.1(a) and 7.1(b) and
the accompanying Officer's Compliance Certificate (such date, the "Adjustment
Date"), setting forth the Total Debt Leverage Ratio as of the most recent fiscal
quarter end; provided that no adjustment shall be made to decrease the
commitment fee at any time that a Default or Event of Default has occurred and
is continuing. In the event the Borrower fails to deliver such financial
statements and the accompanying Officer's Compliance Certificate within the time
required by Sections 7.1 and 7.2 hereof, the commitment fee shall be the highest
commitment fee set forth above until the Adjustment Date following delivery of
such financial statements and the accompanying Officer's Compliance Certificate.


                                       24
<PAGE>   31
      (c) Upfront Fees. The Borrower shall pay to the Agent, for the account of
the Lenders, a non-refundable upfront fee as set forth in the separate fee
letter executed by the Agent and the Borrower dated February 3, 1998.

      SECTION 4.4 Manner of Payment. Each payment by the Borrower on account of
the principal of or interest on the Loans or of any fee or other amounts
(including without limitation the Reimbursement Obligation) payable to the
Lenders under this Agreement or any Note shall be made not later than 2:00 p.m.
(Charlotte time) on the date specified for payment under this Agreement to the
Agent for the account of the Lenders pro rata in accordance with their
respective Commitment Percentages at the Agent's Office, in Dollars, in
immediately available funds and shall be made without any set-off, counterclaim
or deduction whatsoever. Any payment received after such time but before 5:00
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 succeeding Business Day. Any payment received after 5:00
p.m. (Charlotte time) shall be deemed to have been made on the next succeeding
Business Day for all purposes. Upon receipt by the Agent of each such payment,
the Agent shall promptly credit each Lender's account with its pro rata share of
such payment in accordance with such Lender's Commitment Percentage and shall
wire advice of the amount of such credit to each Lender. Each payment to the
Agent of Agent's fees or expenses or to the Issuing Lender of its fees and
expenses and each L/C Participant of any fees owing thereto shall be made in
like manner, but for the account of the Agent, Issuing Lender or L/C
Participant, as the case may be. 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; provided, that if such extension would cause payment of
interest on or principal of any LIBOR Rate Loan to be made in the next calendar
month, such payment shall be made on the next preceding Business Day.

      SECTION 4.5 Nature of Obligations of Lenders Regarding Extensions of
Credit; Assumption by 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 Agent shall have received notice
from a Lender prior to a proposed borrowing date that such Lender will not make
available to the 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 Agent may assume that such Lender has made such
portion available to the Agent on the proposed borrowing date in accordance with
Section 2.2(b), and the 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 Agent on a date after such borrowing date, such Lender
shall pay to the Agent on demand an amount, until paid, equal to the product of
(a) the amount of such Lender's Commitment Percentage of such borrowing, times
(b) the daily average Federal Funds Rate during such period as determined by the
Agent, times (c) 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 Lender's
Commitment Percentage of such borrowing shall have become immediately available
to the Agent and the denominator of which is 360. If such Lender's Commitment
Percentage of such borrowing is not made available to the Agent by such Lender
within three (3) Business Days of such borrowing date, the Agent shall be
entitled to recover such amount made available by the Agent


                                       25
<PAGE>   32
with interest thereon at the rate per annum applicable to such Loan, on demand,
from the Borrower. The Agent shall use reasonable efforts to provide the
Borrower with notice of such Lender's failure to make its Commitment Percentage
available to the Agent prior to any such demand; provided, that the Agent shall
incur no liability whatsoever to the Borrower in the event it fails to do so.
The failure of any Lender to make its Commitment Percentage of any Loan
available shall not relieve it or any other Lender of its obligation, if any,
hereunder to make its Commitment Percentage of such Loan available on such
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 4.6 Changed Circumstances.


      (a) Circumstances Affecting LIBOR Rate Availability. If, with respect to
any Interest Period, the Agent or the Required Lenders (after consultation with
Agent) shall determine that, by reason of circumstances affecting the foreign
exchange and interbank markets generally, the deposits in eurodollars in the
applicable amounts are not being offered (through Telerate Page 3750 or
otherwise) to the Agent or the Required Lenders for such Interest Period, then
the Agent shall forthwith give notice thereof to the Borrower. Thereafter, until
the Agent notifies the Borrower that such circumstances no longer exist (which
notification shall be given promptly, but in any event within ten (10) days
after the Agent obtains actual knowledge that such circumstances no longer
exist), the obligation of the Lenders to make LIBOR Rate Loans, and the right of
the Borrower to convert any Loan to or continue any Loan as a LIBOR Rate Loan,
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 Loan,
together with accrued interest thereon, on the last day of the then current
Interest Period applicable to such LIBOR Rate Loan or convert the then
outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan as
of the last day of such Interest Period.

      (b) Laws Affecting LIBOR Rate 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 by any Lender (or any of their respective Lending
Offices) with any directive 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, such Lender shall promptly give notice
thereof to the Agent and the Agent shall promptly give notice to the Borrower
and the other Lenders. Thereafter, until the Agent notifies the Borrower that
such circumstances no longer exist (which notification shall be given promptly,
but in any event within ten (10) days after the Agent obtains actual knowledge
that such circumstances no longer exist), (i) the obligations of the Lenders to
make LIBOR Rate Loans and the right of the Borrower to convert any Loan or
continue any Loan as a LIBOR Rate Loan 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 to the end of
the then current Interest Period applicable thereto as a LIBOR Rate Loan, the
applicable LIBOR Rate Loan shall immediately be converted to a Base Rate Loan
for the remainder of such Interest Period.


                                       26
<PAGE>   33
      (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 directive 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 LIBOR Rate
Loan or Letter of Credit 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 LIBOR Rate Loan or the amount of any Reimbursement
Obligation in respect of any Letter of Credit (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); 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 other than any change in the Reserve Requirements)
special deposit, insurance 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) with respect to LIBOR Rate Loans or Letters of
Credit 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 LIBOR Rate Loan or Letter of Credit;

and the result of any of the foregoing is to increase the costs to any of the
Lenders of maintaining any LIBOR Rate Loan or issuing or participating in any
Letter of Credit or to reduce the yield or amount of any sum received or
receivable by any of the Lenders under this Agreement, an Application or Letter
of Credit or under the Notes in respect of a LIBOR Rate Loan, then such Lender
shall promptly notify the Agent, and the Agent shall promptly notify the
Borrower of such fact and demand compensation therefor and, within fifteen (15)
days after such notice by 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 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 4.6(c); provided, that the Agent shall incur no
liability whatsoever to the Lenders or the Borrower in the event it fails to do
so. The Agent shall supply the Borrower with a certificate setting forth the
basis for determining such additional amount or amounts necessary to compensate
such Lender or Lenders.

      (d) In the event that any Lender shall determine at any time that by
reason of Regulation D of the Board of Governors of the Federal Reserve System
(or any successor regulation), such Lender is required to maintain Reserve
Requirements during any period that it has any LIBOR Rate Loans outstanding,
then such Lender shall promptly notify the Borrower by written notice (or
telephonic notice promptly confirmed in writing) specifying the additional
amounts reasonably determined by the Lender to be required to indemnify such
Lender against the cost of maintaining such Reserve Requirements (such written
notice to provide a computation of such additional amounts) and the Borrower
shall directly pay to such Lender such specified amounts as additional interest
hereunder.


                                       27
<PAGE>   34
      SECTION 4.7 Indemnity. The Borrower hereby indemnifies each of the Lenders
against any loss or expense actually incurred by such Lender in connection with
such Lender's obtaining, liquidating or employing deposits or other funds
acquired to effect, fund or maintain the Loans (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, (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 on a date other than the last day of the Interest Period
therefor. Each Lender's calculations of any such loss or expense shall be
furnished to the Borrower.

      SECTION 4.8 Capital Requirements. If, after the date of this Agreement,
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 the effect of reducing the rate of return on
the capital of, or has affected the amount of capital required to be maintained
by, any Lender or any corporation controlling such Lender as a consequence of,
or with reference to its Commitment 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) 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 shall be submitted to the Borrower and the Agent by such Lender.

      SECTION 4.9 Taxes.


      (a) Payments Free and Clear. Any and all payments by the Borrower
hereunder or under the Notes 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, in
the case of each Lender and the Agent, income and franchise taxes (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 to any Lender or the 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 4.9) such Lender or 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 Agent
evidence of such payment to the relevant taxing authority or other authority in
the manner provided in Section 4.9(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 (other than income,
franchise, excise and property taxes to which the Agent or any Lender would have
been subject in the absence of this Agreement and the provision for security in
connection with the execution of this Agreement), levies of the United States or
any state or political subdivision thereof or any applicable foreign
jurisdiction which arise from any payment


                                       28
<PAGE>   35
made hereunder or from the execution, delivery or registration of, or otherwise
with respect to, this Agreement, the Loans, 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 Agent for
the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this
Section 4.9) paid by such Lender or the Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto; provided, that this indemnification shall not apply to any
Taxes, Other Taxes or related liability arising as the result of the gross
negligence or willful misconduct of any Lender. Such indemnification shall be
made within thirty (30) days from the date such Lender or the Agent (as the case
may be) makes written demand therefor.

      (d) Evidence of Payment. Within thirty (30) days after the date of any
payment of Taxes or Other Taxes, the Borrower shall furnish to the Agent, at its
address referred to in Section 13.1, the original or a certified copy of a
receipt evidencing payment thereof or other evidence of payment reasonably
satisfactory to the Agent.

      (e) Delivery of Tax Forms. Each Lender organized under the laws of a
jurisdiction other than the United States or any state thereof shall deliver to
the Borrower, with a copy to the Agent, on the Closing Date or concurrently with
the delivery of the relevant Assignment and Acceptance, as applicable, (i) two
United States Internal Revenue Service Forms 4224 or Forms 1001, as applicable
(or successor forms) properly completed and certifying in 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, (ii) an Internal Revenue
Service Form W-8 or W-9 or successor applicable form, as the case may be, to
establish an exemption from United States backup withholding taxes and (iii) any
similar form required by state law. Each such Lender further agrees to deliver
to the Borrower, with a copy to the Agent, a Form 1001 or 4224 and Form W-8 or
W-9, or successor applicable forms or manner of certification, as the case may
be, on or before the date that any such form expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent form
previously delivered by it to the Borrower, certifying in the case of a Form
1001 or 4224 that such Lender is entitled to receive payments under this
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 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.

      (f) Survival. Without prejudice to the survival of any other agreement of
\the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 4.9 shall survive the payment in full of the
Obligations and the termination of the Commitments.

      SECTION 4.10 Change in Lending Office. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of Sections 4.6, 4.7, 4.8,
or 4.9 with respect to


                                       29
<PAGE>   36
such Lender, it will use its best efforts to designate another lending office as
its Lending Office for any Loans affected by such event with the intent of
avoiding the consequence of the event giving rise to the operation of any such
Section; provided, that such designation is made on such terms that such Lender
and its Lending Office suffer no material economic, legal or regulatory
disadvantage as a consequence thereof.

laws of the jurisdiction of its incorporation or formation, has the power and
authority to own its respective properties and to carry on its respective
businesses as now being conducted and is duly qualified and authorized to do
business in each jurisdiction in which the character of its respective
properties or the nature of its respective businesses requires such

6.1(a).

      (b) Subsidiaries and Ownership. Each Subsidiary of the Borrower as of the

binding obligation of the Borrower and each of its Subsidiaries party thereto,
enforceable in accordance with its terms except as such enforcement may be
limited by applicable bankruptcy, insolvency, reorganization or other similar
laws relating to or limiting creditors' rights generally or by general equity

                                       35
<PAGE>   42
      (d) Compliance of Agreement, Notes, Loan Documents and Borrowing with
Laws, Etc. The execution, delivery and performance by the Borrower and its
Subsidiaries of the Loan Documents to which each such Person is a party, the
borrowings hereunder and the transactions contemplated hereby and thereby do not

require any Governmental Approval or violate any Applicable Law relating to the
Borrower or any of its Subsidiaries except those approvals which have been
obtained, (ii) conflict with, result in a breach of or constitute a default
under (A) the articles of incorporation, bylaws or other organizational
documents of the Borrower or any of its Subsidiaries or any Material Contract to
which the Borrower or any of its Subsidiaries is a party or by which any of
their respective properties may be bound or (B) any Governmental Approval
relating to the Borrower or any of its Subsidiaries 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 the Borrower or any of its
Subsidiaries other than Liens arising under the Loan Documents.

      (e) Compliance with Law; Governmental Approvals. Each of the Borrower and
its Subsidiaries (i) have all material Governmental Approvals required by any
Applicable Law for them to conduct their respective businesses, each of which is

not the subject of any pending or, to the knowledge of the Borrower or any of
its Subsidiaries, threatened proceeding, (ii) are in compliance with each
Governmental Approval applicable to them and in compliance with all other
Applicable Laws relating to them or any of their respective properties, except
in each case where the failure to so comply could not reasonably be expected to
have a Material Adverse Effect and (iii) are eligible to participate as
suppliers under Medicare Regulations and Medicaid Regulations, except where the
failure to be eligible could not reasonably be expected to have a Material
Adverse Effect.

      (f) Tax Returns and Payments. Each of the Borrower and its Subsidiaries
have duly filed or caused to be filed all federal, state, local and other tax
returns required by Applicable Law to be filed, and have paid, or made adequate
provision for the payment of, all federal, state, local and other taxes,
assessments and governmental charges or levies upon them and their respective
property, income, profits and assets which are due and payable, except (i) any
such taxes for the current year not yet due and payable, (ii) any such taxes,
assessments, governmental charges or levies which are being contested in good
faith by appropriate proceedings so long as adequate reserves are maintained
with respect thereto in accordance with GAAP and (iii) any such tax returns, the
failure to file, or any such taxes, assessments, governmental charges or levies,

Effect. No Governmental Authority has filed any Lien or asserted any claim
against any the Borrower or its Subsidiaries with respect to material unpaid
taxes which has not been discharged or resolved or is not being contested in
good faith. The charges, accruals and reserves on the books of the Borrower and

liability regarding environmental matters or compliance with Environmental Laws

therewith, nor does the Borrower or its Subsidiaries have knowledge that any
such notice will be received or is being threatened.

or Section 302 of ERISA, nor has there been any event requiring any disclosure
under Section 4041(c)(3)(C) or 4063(a) of ERISA with respect to any Pension
Plan.

         (i) Margin Stock. Neither the Borrower nor any of its Subsidiaries 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 Regulations G and U of the Board of Governors of
the Federal Reserve System). No part 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 G, T, U or X of such Board of Governors.

         (j) Government Regulation. Neither the Borrower nor any of its
Subsidiaries 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 of its
Subsidiaries is, or will be, subject to regulation under the Public Utility
Holding Company Act of 1935, each as amended, or any other Applicable Law which

contemplated hereby.

the loss of which or failure to maintain could reasonably be expected to have a
Material Adverse Effect. Except as set forth on Schedule 6.1(k) and other
matters that could not reasonably be expected to have a Material Adverse Effect,
the Borrower and its Subsidiaries own, license or otherwise possess the lawful
right to use the Intellectual Property and all other similar intangible assets
which are necessary or required to conduct their respective businesses as now
and presently planned to be conducted without conflict with the rights of
others. No event has occurred which permits, or after notice or lapse of time or

Contract.

their employees including, without limitation, fair labor standards laws, wage

Subsidiaries have paid all material federal, state and local withholding, social

         (n) Trade Relations. Other than matters that could not reasonably be
expected to have a Material Adverse Effect, to the knowledge of each of the
Borrower and its Subsidiaries, there exists no actual or threatened termination,
cancellation or limitation of, or any adverse modification or change in, the
business relationship of the Borrower and its Subsidiaries taken as a whole with
any customer or any group of customers whose purchases individually or in the

taken as a whole.

periods involved and present fairly in all material respects the matters
reflected therein subject, in the case of unaudited statements, to changes
resulting from normal year-end audit adjustments and items that would be

as set forth on Schedule 6.1(o), neither the Borrower nor any of its
Subsidiaries have any contingent liability or liability for taxes, long-term
leases or unusual forward or long-term commitments which are not reflected in
the financial statements described above or in the notes thereto and could
reasonably be expected to have a Material Adverse Effect.

         (p) No Material Adverse Change. Except for matters existing on the
Closing Date and set forth on Schedule 6.1(p), since June 30, 1997, no event
which has had or could reasonably be expected to have a Material Adverse Effect

be expected to have a Material Adverse Effect, each of the Borrower and its
Subsidiaries have good and marketable title to, or valid and subsisting
leasehold interests in, the real property owned or leased, as the case may be,
by them and valid and legal title to all of their personal property, including,

terminated, has been filed in any state or other jurisdiction and neither the
Borrower nor any of its Subsidiaries has signed any such financing statement or
any security agreement authorizing any secured party thereunder to file any such
financing statement, except to perfect the Liens permitted by Section 10.3.

         (t) Debt and Guarantees. Schedule 6.1(t) sets forth a complete and
accurate listing as of the Closing Date of all Debt and Guarantees of the

Guarantee.

arbitrator of any kind or before or by any Governmental Authority which could
reasonably be expected to have a Material Adverse Effect.

         (v) Absence of Defaults. No event has occurred or is continuing which
constitutes a Default or an Event of Default. Other than matters that could not
reasonably be expected to have a Material Adverse Effect, no event has occurred
which constitutes a default or event of default by the Borrowers or any
Subsidiary thereof under any judgment, decree or order to which the Borrower or
its Subsidiaries is a party or by which the Borrower or its Subsidiaries or any
of their respective properties may be bound or which would require the Borrower
or its Subsidiaries to make any payment thereunder prior to the scheduled
maturity date therefor.

         (w) Accuracy and Completeness of Information. No document furnished or
written statement made to the Agent or the Lenders by the Borrower or any of its
Subsidiaries 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 material 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 Agents which
could reasonably be expected to have a Material Adverse Effect.

         SECTION 6.2 Survival of Representations and Warranties, Etc. All
representations and warranties made under this Agreement shall survive the
Closing Date and be made or deemed to be made at and as of each borrowing date

undrawn and unexpired amount of such Letters of Credit. Amounts held in such
cash collateral account shall be applied by the Agent to the payment of drafts
drawn under such Letters of Credit, and the unused portion thereof after all
such Letters of Credit shall have expired or been fully drawn upon, if any,
shall be applied to repay the other Obligations. After all such Letters of
Credit shall have expired or been fully drawn upon, the Reimbursement Obligation
shall have been satisfied and all other Obligations shall have been paid in
full, the balance, if any, in such cash collateral account shall be returned to
the Borrower.

         (c) Rights of Collection. Exercise on behalf of the Lenders all of its
other rights and remedies under this Agreement, the other Loan Documents and
Applicable Law, in order to satisfy all of the Credit Parties' Obligations.

         SECTION 11.3. Rights and Remedies Cumulative; Non-Waiver; etc. The
enumeration of the rights and remedies of the Agent and the Lenders set forth in
this Agreement is not intended to be exhaustive and the exercise by the Agent
and the Lenders of any right or remedy shall not preclude the exercise of any
other rights or remedies, all of which shall be cumulative, and shall be in
addition to any other right or remedy given hereunder or under the Loan
Documents or that may now or hereafter exist in law or in equity or by suit or
otherwise. No delay or failure to take action on the part of the 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 Agent and the
Lenders or their respective agents or employees shall be effective to change,
modify or discharge any provision of this Agreement or any of the other Loan
Documents or to constitute a waiver of any Event of Default.

         SECTION 11.4. 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 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 (pro rata in accordance with all such
amounts due) and then to the principal amount of the Notes and Reimbursement
Obligation, and then to the cash collateral account described in Section 11.2(b)
hereof to the effect of any L/C Obligations then outstanding, in that order.

         SECTION 11.5. Set-off. Except to the extent prohibited by law, 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 of any Event
of Default and during the continuance thereof, the Lenders and any assignee of a
Lender in accordance with Section 13.9 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, to set off and to
appropriate and to apply


                                       59
<PAGE>   66
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, excluding government securities required by Applicable Law to be
held as security for worker's compensation and similar claims) 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 Credit Parties against
and on account of the Obligations irrespective of whether or not (a) the Lenders
shall have made any demand under this Agreement or any of the other Loan
Documents or (b) the Agent shall have declared any or all of the Obligations to
be due and payable as permitted by Section 11.2.

                                   ARTICLE XII

                                    THE AGENT

         SECTION 12.1. Appointment. Each of the Lenders hereby irrevocably
designates and appoints First Union as the Agent of such Lender under this
Agreement and the other Loan Documents and each such Lender irrevocably
authorizes First Union as Agent for such Lender, to take such action on its
behalf under the provisions of this Agreement and the other Loan Documents and
to exercise such powers and perform such duties as are expressly delegated to
the Agent by the terms of this Agreement and such other Loan Documents, together
with such other powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere in this Agreement or such other Loan
Documents, the Agent shall not have any duties or responsibilities, except those
expressly set forth herein and therein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or the other Loan
Documents or otherwise exist against the Agent. To the extent any provision of
this Agreement permits action by the Agent, the Agent shall, subject to the
provisions of Section 13.10 hereof and of this Article XII, take such action if
directed in writing to do so by the Required Lenders.

         SECTION 12.2. Delegation of Duties. The Agent may execute any of its
respective duties under this Agreement and the other Loan Documents by or
through agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys-in-fact
selected by the Agent with reasonable care.

         SECTION 12.3. Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or the
other Loan Documents (except for its or such Person's own gross negligence or
willful misconduct), or (b) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrower or
any of its Subsidiaries or any officer thereof contained in this Agreement or
the other Loan Documents or in any certificate, report, statement or other
document referred to or provided for in, or received by such 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
Agent shall be under no obligation to any Lender to ascertain or to


                                       60
<PAGE>   67
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 Agent. The Agent shall be entitled to rely,
and shall be fully protected in relying, upon any note, writing, resolution,
notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Credit Parties), independent
accountants and other experts selected by the Agent. The Agent may deem and
treat the payee of any Note as the owner thereof for all purposes unless such
Note shall have been transferred in accordance with Section 13.9 hereof. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement and the other Loan Documents unless it shall first receive such
advice or concurrence of the Required Lenders (or, when expressly required
hereby or by the relevant other Loan Document, all the Lenders) as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action except for its own gross
negligence or willful misconduct. The Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and the
Notes in accordance with a request of the Required Lenders (or, when expressly
required hereby, all the Lenders), and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Notes.

         SECTION 12.5. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless 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 Agent receives such
a notice, it shall promptly give notice thereof to the Lenders. The Agent shall
take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders; provided that unless and until the
Agent shall have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interests of the Lenders.

         SECTION 12.6. Non-Reliance on the Agent and Other Lenders. Each Lender
expressly acknowledges that neither the 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 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 Agent to any Lender. Each Lender represents to the Agent that it
has, independently and without reliance upon the Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Borrower and its
Subsidiaries and made its own decision to make its Loans and enter into this
Agreement. Each Lender also represents that it will, independently and without
reliance upon the Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time,


                                       61
<PAGE>   68
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 Agent hereunder or by
the other Loan Documents, the 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 and its Subsidiaries which may come into the possession of the 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 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 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 Agent under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the Agent's 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 Agent in Its Individual Capacity. The Agent and its
Subsidiaries and Affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Borrower as though the Agent
were not an Agent hereunder. With respect to any Extensions of Credit made or
renewed by it and any Note issued to it, the Agent shall have the same rights
and powers under this Agreement and the other Loan Documents as any Lender and
may exercise the same as though it were not an Agent, and the terms "Lender" and
"Lenders" shall include the Agent in its individual capacity.

         SECTION 12.9. Resignation of Agent; Successor Agents. Subject to the
appointment and acceptance of a successor as provided below, the Agent may
resign at any time by giving thirty (30) days prior notice thereof to the
Lenders and the Borrower. Upon any such resignation, the Required Lenders shall
have the right to appoint a successor Agent, as the case may be, which successor
shall have minimum capital and surplus of at least $500,000,000 with the consent
of the Borrower, which shall not be unreasonably withheld. If no successor Agent
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within fifteen (15) days after the retiring Agent's giving of
notice of resignation, then the retiring Agent may with the consent of the
Borrower, which shall not be unreasonably withheld, on behalf of the Lenders,
appoint a successor Agent, which successor shall have minimum capital and
surplus of at least $500,000,000. Upon the acceptance of any appointment as
Agent hereunder by a successor


                                       62
<PAGE>   69
Agent, as the case may be, such successor Agent shall thereupon succeed to and
become vested with all rights, powers, privileges and duties of the retiring
Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent's resignation hereunder as
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 the Agent.

                                 ARTICLE XIIIII

                                  MISCELLANEOUS

         SECTION 13.1. Notices.

         (a) Method of Communication. Except as otherwise provided in this
Agreement, all notices and communications hereunder shall be in writing, or by
telephone subsequently confirmed in writing if otherwise permitted by this
Agreement. Any notice shall be effective if delivered by hand delivery or sent
via telecopy, recognized overnight courier service or certified mail, return
receipt requested, and shall be presumed to be received by a party hereto (i) on
the date of delivery if delivered by hand or sent by telecopy, (ii) on the next
Business Day if sent by recognized overnight courier service and (iii) on the
fifth Business Day following the date sent by certified mail, return receipt
requested. A telephonic notice to the Agent as understood by the Agent will be
deemed to be the controlling and proper notice in the event of a discrepancy
with or failure to receive a confirming written notice.

         (b) Addresses for Notices. Notices to any party shall be sent to it at
the following addresses, or any other address as to which all the other parties

out-of-pocket expenses of the Agent in connection with: (a) the preparation,
execution and delivery of this Agreement and each of the other Loan Documents,
whenever the same shall be executed and delivered, including all reasonable

fees, taxes and reasonable fees and disbursements of counsel for the Agent; (b)
the preparation, execution and delivery of any waiver, amendment or consent by

and disbursements of counsel (including the allocated cost of in-house counsel)
and of experts and other consultants retained by the Agent or any of the
Lenders.

         SECTION 13.3. 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,


                                       64
<PAGE>   71
WITHOUT REFERENCE TO THE CONFLICTS OR CHOICE OF LAW PRINCIPLES THEREOF.

         SECTION 13.4. Consent to Jurisdiction. The Borrower hereby irrevocably
consents to the personal jurisdiction of the state and federal courts located in
Mecklenburg 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 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, by the mailing of copies
thereof by registered or certified mail, postage prepaid, to the Borrower at its
address for notices contained in Section 13.1. Nothing in this Section 13.4
shall affect the right of the Agent or any Lender to serve legal process in any
other manner permitted by Applicable Law or affect the right of the Agent or any
Lender to bring any action or proceeding against the Borrower or its properties
in the courts of any other jurisdictions.

         SECTION 13.5. Arbitration.

         (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 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 (the "AAA") and Title 9 of the U.S. Code. All
arbitration hearings shall be conducted in Charlotte, 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. 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 arbitrators shall be appointed as provided in the Arbitration
Rules.

         (b) Preservation of Certain Remedies. Notwithstanding the preceding
binding arbitration provisions, the Agent and the Lenders preserve, without
diminution, certain remedies that the Agent and the Lenders may employ or
exercise freely, either alone, in conjunction with or during a Dispute. The
Agent and the Lenders shall have and hereby reserve 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)


                                       65
<PAGE>   72
all rights of self help including peaceful occupation of property and collection
of rents, set off, and peaceful possession of property and (iii) obtaining
provisional or ancillary remedies including injunctive relief, sequestration,
garnishment, attachment, appointment of receiver and in filing an involuntary
bankruptcy proceeding. 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.

         SECTION 13.6. Waiver of Jury Trial. TO THE EXTENT PERMITTED BY
APPLICABLE LAW, THE AGENT, EACH LENDER AND THE BORROWER HEREBY IRREVOCABLY WAIVE
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.

         SECTION 13.7. Reversal of Payments. To the extent the Borrower makes a
payment or payments to the Agent for the ratable benefit of the Lenders 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 Agent.

         SECTION 13.8. Injunctive Relief. The Borrower recognizes that, in the
event the Borrower fails to perform, observe or discharge any of its obligations
or liabilities under this Agreement, any remedy of law may prove to be
inadequate relief to the Lenders. Therefore, the Borrower agrees that the
Lenders, at the Lenders' option, shall be entitled to temporary and permanent
injunctive relief in any such case without the necessity of proving actual
damages.

         SECTION 13.9. Successors and Assigns; Participations.

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

         (b) Assignment by Lenders. Each Lender may, with the consent of the
Agent and the Borrower (provided, that no consent of the Borrower shall be
required (A) in connection with an assignment from any Lender to one of such
Lender's Affiliates or to another Lender or (B) at any time that a Default or
Event of Default shall have occurred and be continuing), 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 Obligations 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;


                                       66
<PAGE>   73
                  (ii) the Commitment of the assigning Lender after any such
         assignment (determined as of the date the Assignment and Acceptance
         with respect to such assignment is delivered to the Agent) shall in no
         event be less than $5,000,000 and the Commitment so assigned shall not
         be less than $5,000,000 (other than assignments of the entire
         Commitment of a Lender).

                  (iii) the parties to each such assignment shall execute and
         deliver to the Agent, for its acceptance and recording in the Register,
         an Assignment and Acceptance in the form of Exhibit F 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 Agent an assignment
         fee of $3,000 upon the execution by such Lender of the Assignment and
         Acceptance.

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 hereunder
and (B) the Lender thereunder shall, to the extent provided in such assignment,
be released from its obligations under this Agreement.

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

         (d) 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 Agent shall, if such Assignment and Acceptance has been
completed and is substantially in the form of Exhibit F:

                  (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


                                       67
<PAGE>   74
                  (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 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 such Eligible Assignee 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.

         (e) 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
Commitment and the Notes held by it); provided that:

                  (i) each such participation shall be in an amount not less
         than $3,000,000;

                  (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;

                  (v) the Borrower, the 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 of such participant, reduce the amount of
         any fees to which such participant is entitled, or, extend any
         scheduled payment date for principal; 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.

         Any information disclosed by or on behalf of the Borrower or any of its
Subsidiaries or acquired Person to the Agent or any of the Lenders and any
information obtained by the Agent or


                                       68
<PAGE>   75
any of the Lenders pursuant to the provisions of, or in connection with, this
Agreement shall be used solely for purposes of this Agreement and not in any
other manner, and, if such information is not otherwise in the public domain,
shall not be disclosed by the Agent or such Lender to any other Person except
(A) to its independent accountants and legal counsel (it being understood that
the Persons to whom such disclosure is made will be informed of the confidential
nature of such information and instructed to keep such information
confidential), (B) pursuant to statutory and regulatory requirements, (C)
pursuant to any mandatory court order, subpoena or other legal process or (D)
subject to an agreement containing provisions substantially the same as those of
this Section, to any participant in or assignee of, or prospective participant
in or assignee of, any Loan (it being understood that prior to any such
disclosures contemplated by clauses (B) and (C) above, the Agent or such Lender
shall, if practicable, give the Borrower prior written notice of such
disclosure).

         (g) 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.

         SECTION 13.10. Amendments, Waivers and Consents. Except as set forth
below or as otherwise provided herein or in any of the other Loan Documents, any
term, covenant, agreement or condition of this Agreement or any of the other
Loan Documents 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 Agent with the consent of the Required
Lenders) and delivered to the Agent and, in the case of an amendment, signed by
the Borrower; provided, that no amendment, waiver or consent shall (i) increase
the amount or extend the time of the obligation of the Lenders to make Loans or
issue or participate in Letters of Credit, (ii) extend the originally scheduled
time or times of payment of the principal of any Loan or Reimbursement
Obligation, the time or times of payment of interest on any Loan or
Reimbursement Obligation, (iii) reduce the rate of interest or fees payable on
any Loan, (iv) permit any subordination of the principal or interest on any Loan
or Reimbursement Obligation, (v) reduce the "Guaranteed Obligations" as defined
in Subsidiary Guaranty or release the Subsidiary Guarantors from their
obligations under the Subsidiary Guaranty or (vi) amend the provisions of this
Section 13.10, the number of Lenders required to approve any amendment or waiver
otherwise set forth herein, or the definition of Required Lenders or Required
Lenders, without the prior written consent of each Lender. In addition, no
amendment, waiver or consent to the provisions of Article XII shall be made
without the written consent of the Agent.

         SECTION 13.11. Performance of the Borrower's 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 13.12. Indemnification. The Borrower agrees to reimburse the
Agent and the Lenders for all reasonable out-of-pocket costs and expenses,
including all reasonable counsel (including the allocated cost of in-house
counsel), appraisal, or other expert or consultant fees and disbursements
incurred, and to indemnify and hold the Agent and the Lenders harmless from and
against all losses suffered by the Agent and the Lenders in connection with (a)
the exercise by the Agent or the Lenders of any right or remedy granted to them
under this Agreement or any of the other Loan Documents, (b) any claim, and the
prosecution or defense thereof, arising out of or in any way connected with this
Agreement or any of the other Loan Documents, and (c) the collection


                                       69
<PAGE>   76
or enforcement of the Obligations or any of them; provided, that the Borrower
shall not be obligated to reimburse the Agent or any Lender for costs and
expenses, or indemnify the Agent or any Lender for any loss, resulting from the
gross negligence or willful misconduct of the Agent or any Lender.

         SECTION 13.13. All Powers Coupled with Interest. All powers of attorney
and other authorizations granted to the Lenders, the Agent and any Persons
designated by the Agent or Lenders 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 Commitments have not been terminated.

         SECTION 13.14. Survival of Indemnities. Notwithstanding any termination
of this Agreement, the indemnities to which the 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 Agents 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 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.

         SECTION 13.19. Adjustments. If any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of the Obligations (whether
voluntarily or involuntarily, by set-off or otherwise) in a greater proportion
than any such payment to any other Lender, such Benefitted Lender shall purchase
for cash from the other Lenders such portion of each such other Lender's
Extensions of Credit, as shall be necessary to cause such Benefitted Lender to
share the excess payment ratably with each of the Lenders; provided, that if all
or any portion of such excess payment or benefits is thereafter recovered from
such Benefitted 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


                                       70
<PAGE>   77
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 13.20. Independent Effect of Covenants. The Borrower expressly
acknowledges and agrees that each covenant contained in Articles VIII, IX and X
hereof shall be given independent effect. Accordingly, the Borrower shall not
engage in any transaction or other act otherwise permitted under any covenant
contained in Articles VIII, IX or X if, before or after giving effect to such
transaction or act, the Borrower shall or would be in breach of any other
covenant contained in Articles VIII, IX or X.

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 "Subsidiary Guaranty" or herein
to this "Guaranty" shall include and mean this Guaranty, including all
amendments, restatements, modifications and supplements hereto now or hereafter
in effect.

         SECTION 2. Guaranty of Obligations of Borrower. Each Guarantor hereby,
jointly and severally with the other Guarantors, unconditionally guarantees to
the Agent for the ratable benefit of itself and the Lenders, and their
respective successors, endorsees, transferees and assigns, the prompt payment
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 Agent or any Lender or acquired by
the 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 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 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 each Guarantor 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 Guaranteed
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. Section 547, Section 548,
Section 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
<PAGE>   95
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 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 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) the absence of any action to enforce this Guaranty, the
         Credit Agreement or any other Loan Document or the waiver or consent by
         the Agent or any Lender with respect to any of the provisions of this
         Guaranty, the Credit Agreement or any other Loan Document;

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

                  (d) 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
hereof, 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. To the extent permitted by
Applicable Law, 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 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. To the extent permitted by Applicable Law, each Guarantor
further expressly waives and agrees not to assert or take advantage of any
defense based upon the failure of the Agent or any Lender to commence an action
in respect of the Guaranteed Obligations against the Borrower, such 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 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 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. The foregoing waivers are of the essence of the
transaction contemplated by the Loan Documents and, but for this Guaranty and
such waivers, the Agent and Lenders would decline to enter into the Credit
Agreement.

         SECTION 4. Demand by the 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 under the Credit
Agreement are declared to be immediately due and payable, then the Guarantors
shall, upon demand in 
<PAGE>   96
writing therefor by the Agent to the Guarantors, pay all or such portion of the
outstanding Guaranteed Obligations then declared due and payable. Payment by the
Guarantors shall be made to the Agent, to be credited and applied upon the
Guaranteed Obligations, in immediately available Dollars to an account
designated by the Agent or at the address referenced herein for the giving of
notice to the Agent or at any other address that may be specified in writing
from time to time by the Agent.

         SECTION 5. Waivers. In addition to the waivers contained in Section 3,
each Guarantor, to the extent permitted by law, 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 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 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 Agent and the Lenders and their respective successors,
transferees, endorsees and assigns, and nothing herein contained shall impair,
as between the Borrower, the 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 Agent or any
Lender to any Person or Persons, any reference to an "Agent", or "Lender" herein
shall be deemed to refer equally to such Person or Persons.

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

                  (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, in equity or otherwise, 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, 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 Agent or the Lenders have been granted a Lien, to secure any
         Debt of any Guarantor, any other guarantor or the Borrower to the 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 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 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 Agent or any Lender in such manner as the Agent or any Lender shall
         determine in its reasonable discretion;
<PAGE>   97
then neither the 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 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, if any) 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 and Warranties. To induce the Lenders to
make any Loans, each Guarantor hereby represents and warrants 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 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
         Contract 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; and

                  (g) as of the Closing Date, such Guarantor (i) 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, (ii) owns property having a value, both at fair valuation
         and at present fair saleable value, greater than the amount required to
         pay its probable liabilities (including contingencies) and (iii) does
         not believe that it will incur debts or liabilities beyond its ability
         to pay such debts or liabilities as they mature.
<PAGE>   98
         SECTION 10.  Remedies.

         (a) Upon the occurrence of any Event of Default, with the consent of
the Required Lenders, the Agent may, or upon the request of the Required
Lenders, the 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 Agent hereunder, under the Loan Documents or
otherwise.

         (b) No right or remedy herein conferred upon the 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 Agent to
pursue, or refrain from pursuing, any remedy available to the 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 Guarantor not then exercised. In addition, any election of remedies
which results in the denial or impairment of the right of the 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 Agent or any Lender, or the receipt of any amounts by
the 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
Agent or any Lender against the Borrower or the other Guarantors or against any
collateral security held by the 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 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 Agent, segregated from other funds of
such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned
over to the Agent in the exact form received by such Guarantor (duly endorsed by
such Guarantor to the 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 Agent, consented to by such
Lenders as required by Section 13.10 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 or amplify the
provisions of this Guaranty.

         (c) Notices. All notices and communications hereunder shall be given in
accordance with Section 13.1 of the Credit Agreement.

         (d) Binding Effect. This Guaranty shall bind each Guarantor and shall
inure to the benefit of the Agent and Lenders and their respective successors
and assigns. No Guarantor may assign this Guaranty or delegate any of its duties
hereunder, other than in connection with the merger of such Guarantor into such
other Person as permitted by Section 10.5 of the Credit Agreement.

         (e) Non-Waiver. The failure of the 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
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.

         (f) Termination. This Guaranty shall terminate and be of no further
force or effect on the date when the Guaranteed Obligations have been
indefeasibly paid in full.
<PAGE>   99
         (g) 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.

         (h) Consent to Jurisdiction. Each Guarantor hereby irrevocably consents
to the personal jurisdiction of the state and federal courts located in
Mecklenburg 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 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(c). Nothing in this Section
12(h) shall affect the right of the Agent or any Lender to serve legal process
in any other manner permitted by Applicable Law or affect the right of the Agent
or any Lender to bring any action or proceeding against any Guarantor or its
properties in the courts of any other jurisdictions.

         (i)      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 Title 9 of the U.S. Code. All
         arbitration hearings shall be conducted in Charlotte, 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. 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.

                  (ii) JURY TRIAL. TO THE EXTENT PERMITTED BY APPLICABLE LAW,
         THE AGENT, EACH LENDER AND EACH GUARANTOR HEREBY IRREVOCABLY WAIVE
         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 the
         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.
<PAGE>   100
         (j) Expenses. The Guarantors agree that they will reimburse the Agent
and each Lender for all reasonable out-of-pocket expenses (including reasonable
attorneys' fees and expenses) incurred by such Agent or 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 Agent in
connection with the amendment or modification of this Guaranty.

         (k) Indemnities. Each Guarantor agrees to hold the Agent and the
Lenders harmless from and against all losses suffered by the Agent and the
Lenders in connection with (i) the exercise by the 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 or any of
them; provided, that such Guarantor shall not be obligated to reimburse the
Agent or the Lenders for costs and expenses, or indemnify the Agent or the
Lenders for any loss, resulting from the gross negligence or willful misconduct
of the Agent or the Lenders. Notwithstanding any termination of this Guaranty,
the indemnities to which the Agent and Lenders are entitled under this Guaranty
shall continue in full force and effect and shall protect the Agent and the
Lenders against events arising after such termination as well as before.


                           [SIGNATURE PAGES TO FOLLOW]

CAROLINA), as agent (the "Agent") for the Lenders party to the Credit Agreement
dated as of March 16, 1998 by and among the Borrower, the financial institutions

                              Statement of Purpose


         The Credit Agreement requires that the Intercompany Loan Parties agree
to subordinate all intercompany obligations owing by any Intercompany Loan Party
to any other Intercompany Loan Party to all obligations owed to the Agent or any
Lender under the Credit Agreement or any other Loan Document (the "Senior
Indebtedness") by any of the Intercompany Loan Parties.

         To induce the Lenders to enter into the Credit Agreement, the
Intercompany Loan Parties have agreed to enter into this Intercompany
Subordination Agreement with respect to all such intercompany obligations.
Capitalized terms used herein and not defined herein shall have the meanings
assigned thereto in the Credit Agreement.


         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

SECTION 1.        SUBORDINATION.

         1.01. Subordination to Senior Indebtedness.

         Each Intercompany Loan Party for itself and its successors agrees that,
to the extent it is from time to time entitled to receive payment in respect of
any intercompany loan, advance or other account from any other Intercompany Loan
Party (a "Subordinated Obligation"), the payment of the principal of, premium,
if any, interest on (including all interest accruing thereon subsequent to a
Bankruptcy Event ("post-petition interest")) or other fees, costs, expenses and
any other amounts accrued, incurred or otherwise due in connection with all such
Subordinated Obligations from time to time, is subordinated in right of payment,
to the extent and in the manner provided herein, to the payment in full of all
Senior Indebtedness.


                                       2
<PAGE>   124
         1.02.    No Payment on the Subordinated Obligations in Certain
                  Circumstances.

         (a)      No payment shall be made, either directly or indirectly, by or
on behalf of any Intercompany Loan Party, in cash, property or securities on
account of the principal of, premium, if any, and interest (including
post-petition interest) on any Subordinated Obligation at the time outstanding,
or other fees, costs, expenses and any other amounts accrued, incurred or
otherwise due in respect of any such Subordinated Obligation, or to prepay,
purchase, redeem, retire, exchange, defease or otherwise acquire any
Subordinated Obligation or any instrument evidencing a Subordinated Obligation
for cash or property (collectively, "Subordinated Payments"), (i) upon the
maturity of any Senior Indebtedness by acceleration or otherwise, unless and
until all principal of, interest (including post-petition interest) and premium,
if any, on and all other fees, costs, expenses and other amounts accrued or
incurred pursuant to the terms of the Senior Indebtedness then due, shall have
first been paid in full or waived, or (ii) upon the occurrence of any Event of
Default with respect to any Senior Indebtedness (unless and until such Event of
Default shall have been cured or waived in accordance with the terms of the
Credit Agreement).

         (b)      In furtherance of the provisions of Section 1.01, in the event
that, notwithstanding the foregoing provisions of subsection 1.02, any
Subordinated Payment, either directly or indirectly, shall be made by or on
behalf of any Intercompany Loan Party, and received by another Intercompany Loan
Party at a time when such payment was prohibited by the provisions of this
subsection 1.02, then, unless and until such payment is no longer prohibited by
this subsection 1.02, such payment shall be segregated and held in trust for the
benefit of and shall be promptly paid over to, the Agent, for the benefit of the
Lenders.

         (c)      The Borrower shall give prompt written notice to each other
Intercompany Loan Party of any Event of Default with respect to such Senior
Indebtedness. Failure to give such notice shall not affect the subordination of
the Subordinated Obligations to the Senior Indebtedness provided in this
Intercompany Subordination Agreement.

         1.03.    Subordination of Intercompany Obligations on Dissolution,
                  Liquidation or Reorganization of an Intercompany Loan Party.

         Upon any distribution by any Intercompany Loan Party of assets of any
kind or character, whether in cash, property or securities, to creditors upon
any dissolution, winding up, liquidation or reorganization (excluding, so long
as no Default or Event of Default shall have occurred and be continuing,
mergers, sales of assets and other combinations permitted pursuant to Sections
10.5, 10.6(d) and 10.6(e) of the Credit Agreement) of such Intercompany Loan
Party (the "Liquidating Loan Party") (whether in a voluntary or involuntary
bankruptcy, insolvency or receivership proceedings or upon any assignment for
the benefit of creditors or otherwise):

                  (a)      the Lenders shall first receive payment in full in
         cash, to the extent then presently available for payment, of the
         principal, interest (including all interest accruing on the Senior
         Indebtedness subsequent to a Bankruptcy Event ("post-petition interest
         on Senior Indebtedness")) and premium, if any, due thereon and all
         other fees, costs, expenses, or other amounts accrued or incurred
         pursuant to the terms thereof (or have such payments duly provided for
         in a manner reasonably satisfactory to holders of Senior Indebtedness
         or their representative) before any other Intercompany Loan Party is
         entitled to receive any Subordinated Payment on account of or accrued
         or incurred in connection with any Subordinated Obligation;

                  (b)      any payment or distribution of assets of the
         Liquidating Loan Party of any kind or character, whether in cash,
         property or securities to which such other Intercompany Loan Party
         would be entitled except for the provisions of this Intercompany
         Subordination Agreement shall be paid by the Liquidating Loan Party,
         the liquidating trustee or agent or other person making such a payment
         or distribution, directly to the Agent, for the benefit of the Lenders,
         to the extent necessary to make payment in full of all Senior
         Indebtedness remaining unpaid; and

                  (c)      in the event that, notwithstanding the foregoing, any
         payment or distribution of assets of the Liquidating Loan Party of any
         kind or character, whether in cash, property or securities,


                                       3
<PAGE>   125
         shall be received by any such other Intercompany Loan Party on account
         of, or accrued or incurred in connection with, any Subordinated
         Obligation before all Senior Indebtedness is paid in full in cash, or
         effective provision (in a manner reasonably satisfactory to the
         Lenders) made for its payment, then such payment or distribution shall
         be segregated and received and held in trust for the benefit of and
         shall be promptly paid over to the Agent, for the benefit of the
         Lenders, for application to the payment of all Senior Indebtedness
         until such Senior Indebtedness shall have been paid in full (including
         post-petition interest on the Senior Indebtedness).

         The Borrower shall give prompt written notice to the Agent and each
Intercompany Loan Party of any dissolution, winding up, liquidation or
reorganization of any Intercompany Loan Party, but failure to give such notice
shall not affect the subordination of the Subordinated Obligations to the Senior
Indebtedness provided in this Intercompany Subordination Agreement.

         1.04.    Subrogation.

         Subject to the payment in full of all Senior Indebtedness, the holder
of, or obligee with respect to, any Subordinated Obligation shall be subrogated
to the rights of the Lenders to receive payments or distributions of assets of
an Intercompany Loan Party applicable to the Senior Indebtedness to the extent
that distributions were paid to the Lenders that otherwise would have been paid
to such obligee, until all amounts owing on such Subordinated Obligation shall
be paid in full, and for the purpose of such subrogation no such payments or
distributions to the Lenders by virtue of this Intercompany Subordination
Agreement, which otherwise would have been made to such obligee, shall, as
between the obligor on such Subordinated Obligation and such obligee, be deemed
to be payment on account of such Subordinated Obligation, it being understood
that the provisions of this Intercompany Subordination Agreement are and are
intended solely for the purpose of defining the relative rights of the
Intercompany Loan Parties, on the one hand, and the Lenders, on the other hand.

         1.05.    Subordination Rights Not Impaired.

         (a)      No right of the Agent or any Lender to enforce subordination
as provided herein shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of any Intercompany Loan Party or by any act
or failure to act, in good faith, by the Agent or any such Lender, or by any
noncompliance by any Intercompany Loan Party with the terms of any Subordinated
Obligation, regardless of any knowledge thereof which any such Lender may have
or be otherwise charged with. The Agent and the Lenders may extend, renew,
modify or amend the terms of Senior Indebtedness or any security therefor and
release, sell or exchange such security and otherwise deal freely with any
Intercompany Loan Party, all without affecting the liabilities and obligations
of any other Intercompany Loan Party or the rights of the Agent and the Lenders
hereunder.

         (b)      All rights and interests hereunder or under any Subordinated
Obligation of the Agent and the Lenders, and all agreements and obligations of
the Intercompany Loan Parties under this Intercompany Subordination Agreement,
shall remain in full force and effect irrespective of (i) any lack of validity
or enforceability of the Credit Agreement or any other Loan Document, or of any
provision of any thereof or (ii) any other circumstance that might otherwise
constitute a defense available to, or a discharge of, any Intercompany Loan
Party in respect of the Senior Indebtedness.

         1.06.    Authorization to Effect Subordination.

         Each Intercompany Loan Party, by its acceptance hereof, solely in its
capacity as obligee with respect to Subordinated Obligations, upon the
occurrence and during the continuation of an Event of Default under the Credit
Agreement, (a) irrevocably authorizes and empowers (but without imposing any
obligation on) the Agent (through its authorized representatives), on behalf of
itself and the Lenders, to demand, sue for, collect and receive such obligee's
ratable share of payments or distributions with respect to Subordinated
Obligations which are required to be paid or delivered to the Lenders as
provided herein, and take all such other action, in the name of such obligee or
otherwise, as such authorized representatives may determine to be necessary or
appropriate for the enforcement of the provisions of this Intercompany
Subordination Agreement, including without limitation, that (i) such
representatives shall have the right to vote such obligee's interest in any
proceeding under the Bankruptcy Law as such vote relates to any Subordinated
Obligation or Subordinated Payment and (ii) in any such proceeding such
representatives may, as attorney-in-fact for such obligee, file any claim, proof
of claim or such other instrument of similar character, in each case, solely to
the extent such proof of claim or such other instrument relates to any
Subordinated Obligation or Subordinated Payment; and (b) agrees to execute and
deliver to such representatives, all such further instruments confirming the
authorization hereinabove set forth, and all such powers of attorney, proofs of
claim, assignments of claim and other instruments as may reasonably be requested
by the Agent.

Rural/Metro Corporation

Scottsdale, Arizona  85251

Ladies and Gentlemen:

         We have acted as counsel for Rural/Metro Corporation, a Delaware
corporation (the "Company"), in connection with the proposed offer by the
Company to exchange (the "Exchange Offer") all outstanding 7-7/8% Senior Notes
Due 2008 ($150.0 million principal amount outstanding) (the "Outstanding Notes")
for 7-7/8% Senior Notes due 2008 ($150.0 million principal amount) (the
"Exchange Notes"). The Outstanding Notes have been, and the Exchange Notes will
be, issued pursuant to an Indenture dated as of March 16, 1998 (the
"Indenture"), among the Company, certain of its subsidiaries (the "Subsidiary
Guarantors") and The First National Bank of Chicago, as trustee (the "Trustee").
Unless otherwise defined herein capitalized terms used in this opinion shall
have the meanings set forth in the Indenture.

         We have examined (i) the Indenture, (ii) the form of Exchange Notes,
which are filed as Exhibit 4.2 to the Registration Statement, (iii) the
Registration Statement on Form S-4, filed by the Company with the Securities and
Exchange Commission, for the registration of the Exchange Notes under the
Securities Act of 1933 (the Registration Statement as amended at the time it
becomes effective being referred to as the "Registration Statement"), and (iv)
such corporate records of the Company, certificates of public officials and such
other documents as we have deemed necessary or appropriate for the purpose of
this opinion.

         For purposes of this opinion, we have assumed (i) the legal capacity of
all natural persons executing the documents examined by us; (ii) that the
documents and signatures examined by us are genuine and authentic; (iii) the due
authorization, execution and delivery of the Indenture by the Trustee; (iv) that
the Trustee has the requisite power and authority to enter into the Indenture
and to act as trustee thereunder (and is eligible and duly qualified to act in
such capacity); and (v) that the Indenture constitutes the legal, valid and
binding obligation of the Trustee, enforceable against the Trustee in accordance
with its terms.

         On the basis of the foregoing, we express the following opinions:

                  (i) the Exchange Notes, when duly executed, authenticated and
exchanged in accordance with the terms of the Indenture entered into among the
Company, the Subsidiary Guarantors and the Trustee, will constitute valid and
binding obligations of the Company, enforceable against the Company in
accordance with their terms and entitled to the benefits of the Indenture,
except that (i) the enforcement thereof may be subject to bankruptcy,
insolvency, moratorium, reorganization, arrangement, fraudulent transfer or
conveyance and other similar laws now or hereafter in effect relating to
creditors' rights generally, and to general principles of equity and the
discretion of the court before which any proceeding therefor may be brought;
(ii) the remedy of specific performance and injunctive and other forms of
equitable relief are subject to certain equitable defenses and to the discretion
of the court before which any proceeding therefor may be brought; (iii) the
enforceability of provisions imposing penalties, forfeitures, late payment
charges or an increase in interest rate upon delinquency in payment or the
occurrence of a default may be limited in certain circumstances; (iv) the
enforceability of any provision requiring the payment of attorney's fees may be
subject to a court determination that such fees are reasonable; and (v) any
rights to indemnity or contribution thereunder may be limited by federal or
state securities laws and public policy considerations.

                  (ii) the Guarantees, when issued by the Subsidiary Guarantors
upon the execution, authentication and exchange of the Exchange Notes, will each
constitute a valid and binding obligation of the Subsidiary Guarantors in
accordance with their terms, except that (i) the enforcement thereof may be
subject to bankruptcy, insolvency, moratorium, reorganization, arrangement,
fraudulent transfer or conveyance and other similar laws now or hereafter in
effect relating to creditors' rights generally, and to general principles of
equity and the discretion of the court before which any proceeding therefor may
be brought; (ii) the remedy of specific performance and injunctive and other
forms of equitable relief are subject to certain equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought;
(iii) the enforceability of provisions imposing penalties, forfeitures, late
payment charges or an increase in interest rate upon delinquency in payment or
the occurrence of a default may be limited in certain circumstances; (iv) the
enforceability of any provision requiring the payment of attorney's fees may be
subject to a court determination that such fees are reasonable; and (v) any
rights to indemnity or contribution thereunder may be limited by federal or
state securities laws and public policy considerations.

         We are members of the Bar of the State of Arizona and we do not purport
to be experts on, or to express any opinion as to the laws of any jurisdiction
other than the applicable federal laws of the United States, the General
Corporation Law of the State of Delaware and the laws of the State of Arizona.
We note that the Indenture states that it is to be governed by the laws of the
State of New York. We are not familiar with the laws of New York and render no

opinion about them. For the purposes of this opinion, we have assumed that the
Indenture will be governed by the laws of the State of Arizona, notwithstanding
its express terms. We express no opinion about what laws will actually govern
the Indenture. Further, our opinion is based solely upon existing laws, rules
and regulations, and we undertake no obligation to advise you of any changes
that may be brought to our attention after the date hereof.

         We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement and to the reference to the firm under "Legal Matters" in
the Prospectus forming a part of the Registration Statement.

                                             Very truly yours,

                                             O'Connor, Cavanagh, Anderson,
                                               Killingsworth & Beshears, P.A.
