                                    SECTION 2

                                CREDIT FACILITIES

     2.1  Revolving Loans.

               (a) Revolving Commitment. Subject to the terms and conditions
          hereof and in reliance upon the representations and warranties set
          forth herein, each Lender severally agrees to make available to the
          Borrower such Lender's Revolving Commitment Percentage of revolving
          credit loans requested by the Borrower in Dollars ("Revolving Loans")
          from time to time from the Amendment No. 4 Effective Date until the
          Maturity Date, or such earlier date as the Revolving Commitments shall
          have been terminated as provided herein for the purposes hereinafter
          set forth; provided, however, that the sum of the aggregate principal
          amount of outstanding Revolving Loans shall not exceed TWENTY-FIVE
          MILLION DOLLARS ($25,000,000) (as such aggregate maximum amount may be
          reduced from time to time as provided in Section 3.4, the "Revolving
          Committed Amount"); provided, further, (A) with regard to each Lender
          individually, such Lender's outstanding Revolving Loans shall not
          exceed such Lender's Revolving Commitment Percentage of the Revolving
          Committed Amount, and (B) the aggregate principal amount of
          outstanding Revolving Loans plus LOC Obligations outstanding shall not
          exceed the Revolving Committed Amount. Revolving Loans may consist of
          Base Rate Loans or Eurodollar Loans, or a combination thereof, as the
          Borrower may request; provided, however, that no more than 16
          Eurodollar Loans shall be outstanding hereunder at any time. For
          purposes hereof, Eurodollar Loans with different Interest Periods
          shall be considered as separate Eurodollar Loans, even if they begin
          on the same date, although borrowings, extensions and conversions may,
          in accordance with the provisions hereof, be combined at the end of
          existing Interest Periods to constitute a new Eurodollar Loan with a
          single Interest Period. Revolving Loans hereunder may be repaid and
          reborrowed in accordance with the provisions hereof.

               (b) Revolving Loan Borrowings.

                    (i) Notice of Borrowing. The Borrower shall request a
               Revolving Loan borrowing by written notice (or telephonic notice
               promptly confirmed in writing) to the Agent not later than 12:00
               Noon (Charlotte, North Carolina time) on the Business Day prior
               to the date of the requested borrowing in the case of Base Rate
               Loans, and on the third Business Day prior to the date of the
               requested borrowing in the case of Eurodollar Loans. Each such
               request for borrowing shall be irrevocable and shall specify (A)
               that a Revolving Loan is requested, (B) the date of the requested
               borrowing (which shall be a Business Day), (C) the aggregate
               principal amount to be borrowed, and (D) whether the borrowing
               shall be comprised of Base Rate Loans, Eurodollar Loans or a
               combination thereof, and if Eurodollar Loans are requested, the
               Interest Period(s) therefor. If the Borrower shall fail to
               specify in any such Notice of Borrowing (I) an applicable
               Interest Period in the case of a Eurodollar Loan, then such
               notice shall be deemed to be a request for an Interest Period of
               one month, or (II) the type of Revolving Loan requested, then
               such notice shall be deemed to be a request for a Base Rate Loan
               hereunder. The Agent shall give notice to each affected Lender
               promptly upon receipt of each Notice of Borrowing pursuant to
               this Section 2.1(b)(i), the contents thereof and each such
               Lender's share of any borrowing to be made pursuant thereto.

                    (ii) Minimum Amounts. Each Eurodollar Loan and Base Rate
               Loan that is a Revolving Loan shall be in a minimum aggregate
               principal amount of $1,000,000 and integral multiples of $100,000
               in excess thereof (or the remaining amount of the Revolving
               Committed Amount, if less).

                    (iii) Advances. Each Lender will make its Revolving
               Commitment Percentage of each Revolving Loan borrowing available
               to the Agent for the account of the Borrower as specified in
               Section 3.15(a), or in such other manner as the Agent may specify
               in writing, by 2:00 P.M. 



                                       23


               (Charlotte, North Carolina time) on the date specified in the
               applicable Notice of Borrowing in Dollars and in funds
               immediately available to the Agent. Such borrowing will then be
               made available to the Borrower by the Agent by crediting the
               account of the Borrower on the books of such office with the
               aggregate of the amounts made available to the Agent by the
               Lenders and in like funds as received by the Agent.

               (c) Repayment. The principal amount of all Revolving Loans shall
          be due and payable in full on the Maturity Date, unless accelerated
          sooner pursuant to Section 9.2.

               (d) Interest. Subject to the provisions of Section 3.1,

                         (i) Base Rate Loans. During such periods as Revolving
                    Loans shall be comprised in whole or in part of Base Rate
                    Loans, such Base Rate Loans shall bear interest at a per
                    annum rate equal to the Adjusted Base Rate.

                         (ii) Eurodollar Loans. During such periods as Revolving
                    Loans shall be comprised in whole or in part of Eurodollar
                    Loans, such Eurodollar Loans shall bear interest at a per
                    annum rate equal to the Adjusted Eurodollar Rate.


          Interest on Revolving Loans shall be payable in arrears on each
          applicable Interest Payment Date (or at such other times as may be
          specified herein).

               (e) Revolving Notes. The Revolving Loans made by each Lender
          shall be evidenced by a duly executed promissory note of the Borrower
          to such Lender in an original principal amount equal to such Lender's
          Revolving Commitment Percentage of the Revolving Committed Amount and
          in substantially the form of Exhibit 2.1(e).

          2.2  Letter of Credit Subfacility.

               (a) Issuance. Subject to the terms and conditions hereof and of
          the LOC Documents, if any, and any other terms and conditions which
          the Issuing Lender may reasonably require and in reliance upon the
          representations and warranties set forth herein, the Issuing Lender
          agrees to issue, and each Lender severally agrees to participate in
          the issuance by the Issuing Lender of, standby and trade Letters of
          Credit in Dollars from time to time from the Amendment No. 4 Effective
          Date until the date five (5) days prior to the Maturity Date as the
          Borrower may request, in a form acceptable to the Issuing Lender;
          provided, however, that (i) the LOC Obligations outstanding shall not
          at any time exceed EIGHT MILLION DOLLARS ($8,000,000) (the "LOC
          Committed Amount") and (ii) the sum of the aggregate principal amount
          of outstanding Revolving Loans plus LOC Obligations outstanding shall
          not at any time exceed the Revolving Committed Amount. No Letter of
          Credit shall (x) have an original expiry date more than one year from
          the date of issuance or (y) as originally issued or as extended, have
          an expiry date extending beyond the Maturity Date. Each Letter of
          Credit shall comply with the related LOC Documents. The issuance and
          expiry dates of each Letter of Credit shall be a Business Day.

               (b) Notice and Reports. The request for the issuance of a Letter
          of Credit shall be submitted by the Borrower to the Issuing Lender at
          least three (3) Business Days prior to the requested date of issuance.
          The Issuing Lender will, at least quarterly and more frequently upon
          request, disseminate to each of the Lenders a detailed report
          specifying the Letters of Credit which are then issued and outstanding
          and any activity with respect thereto which may have occurred since
          the date of the prior report, and including therein, among other
          things, the beneficiary, the face amount and the expiry date, as well
          as any payment or expirations which may have occurred.

               (c) Participation. Each Lender, upon issuance of a Letter of
          Credit, shall be deemed to have purchased without recourse a
          Participation Interest from the applicable Issuing Lender in such
          Letter of Credit and the obligations arising thereunder and any
          collateral relating thereto, in each case in an amount equal to its
          pro rata share of the obligations under such Letter of Credit (based
          on the respective Revolving Commitment Percentages of the Lenders) and
          shall absolutely, unconditionally and irrevocably assume and be
          obligated to 



                                       24


          pay to the Issuing Lender and discharge when due, its pro rata share
          of the obligations arising under such Letter of Credit. Without
          limiting the scope and nature of each Lender's Participation Interest
          in any Letter of Credit, to the extent that the Issuing Lender has not
          been reimbursed as required hereunder or under any such Letter of
          Credit, each such Lender shall pay to the Issuing Lender its pro rata
          share of such unreimbursed drawing in same day funds on the day of
          notification by the Issuing Lender of an unreimbursed drawing pursuant
          to the provisions of subsection (d) below. The obligation of each
          Lender to so reimburse the Issuing Lender shall be absolute and
          unconditional and shall not be affected by the occurrence of a
          Default, an Event of Default or any other occurrence or event. Any
          such reimbursement shall not relieve or otherwise impair the
          obligation of the Borrower to reimburse the Issuing Lender under any
          Letter of Credit, together with interest as hereinafter provided.

               (d) Reimbursement. In the event of any drawing under any Letter
          of Credit, the Issuing Lender will promptly notify the Borrower.
          Unless the Borrower shall immediately notify the Issuing Lender that
          the Borrower intends to otherwise reimburse the Issuing Lender for
          such drawing, the Borrower shall be deemed to have requested that the
          Lenders make a Revolving Loan in the amount of the drawing as provided
          in subsection (e) below on the related Letter of Credit, the proceeds
          of which will be used to satisfy the related reimbursement
          obligations. The Borrower promises to reimburse the Issuing Lender on
          the day of drawing under any Letter of Credit (either with the
          proceeds of a Revolving Loan obtained hereunder or otherwise) in same
          day funds. If the Borrower shall fail to reimburse the Issuing Lender
          as provided hereinabove, the unreimbursed amount of such drawing shall
          bear interest at a per annum rate equal to the Adjusted Base Rate plus
          2%. The Borrower's reimbursement obligations hereunder shall be
          absolute and unconditional under all circumstances irrespective of any
          rights of setoff, counterclaim or defense to payment the Borrower may
          claim or have against the Issuing Lender, the Agent, the Lenders, the
          beneficiary of the Letter of Credit drawn upon or any other Person,
          including without limitation any defense based on any failure of the
          Borrower or any other Credit Party to receive consideration or the
          legality, validity, regularity or unenforceability of the Letter of
          Credit. The Issuing Lender will promptly notify the other Lenders of
          the amount of any unreimbursed drawing and each Lender shall promptly
          pay to the Agent for the account of the Issuing Lender in Dollars and
          in immediately available funds, the amount of such Lender's pro rata
          share of such unreimbursed drawing. Such payment shall be made on the
          day such notice is received by such Lender from the Issuing Lender if
          such notice is received at or before 2:00 P.M. (Charlotte, North
          Carolina time) otherwise such payment shall be made at or before 12:00
          Noon (Charlotte, North Carolina time) on the Business Day next
          succeeding the day such notice is received. If such Lender does not
          pay such amount to the Issuing Lender in full upon such request, such
          Lender shall, on demand, pay to the Agent for the account of the
          Issuing Lender interest on the unpaid amount during the period from
          the date of such drawing until such Lender pays such amount to the
          Issuing Lender in full at a rate per annum equal to, if paid within
          two (2) Business Days of the date that such Lender is required to make
          payments of such amount pursuant to the preceding sentence, the
          Federal Funds Rate and thereafter at a rate equal to the Base Rate.
          Each Lender's obligation to make such payment to the Issuing Lender,
          and the right of the Issuing Lender to receive the same, shall be
          absolute and unconditional, shall not be affected by any circumstance
          whatsoever and without regard to the termination of this Credit
          Agreement or the Commitments hereunder, the existence of a Default or
          Event of Default or the acceleration of the obligations of the
          Borrower hereunder and shall be made without any offset, abatement,
          withholding or reduction whatsoever. Simultaneously with the making of
          each such payment by a Lender to the Issuing Lender, such Lender
          shall, automatically and without any further action on the part of the
          Issuing Lender or such Lender, acquire a Participation Interest in an
          amount equal to such payment (excluding the portion of such payment
          constituting interest owing to the Issuing Lender) in the related
          unreimbursed drawing portion of the LOC Obligation and in the interest
          thereon and in the related LOC Documents, and shall have a claim
          against the Borrower with respect thereto.

               (e) Repayment with Revolving Loans. On any day on which the
          Borrower shall have requested, or been deemed to have requested, a
          Revolving Loan advance to reimburse a drawing under a Letter of
          Credit, the Agent shall give notice to the Lenders that a Revolving
          Loan has been requested or deemed requested by the Borrower to be made
          in connection with a drawing under a Letter of Credit, in which case a
          Revolving Loan advance comprised of Base Rate Loans (or Eurodollar
          Loans to the extent the Borrower has complied with the procedures of
          Section 2.1(b)(i) with respect thereto) shall be immediately made to
          the Borrower by all Lenders (notwithstanding any termination of the
          Commitments pursuant to Section 9.2) pro rata based on the respective
          Revolving Commitment Percentages of the Lenders (determined 


                                       25



          before giving effect to any termination of the Commitments pursuant to
          Section 9.2) and the proceeds thereof shall be paid directly to the
          Issuing Lender for application to the respective LOC Obligations. Each
          such Lender hereby irrevocably agrees to make its pro rata share of
          each such Revolving Loan immediately upon any such request or deemed
          request in the amount, in the manner and on the date specified in the
          preceding sentence notwithstanding (i) the amount of such borrowing
          may not comply with the minimum amount for advances of Revolving Loans
          otherwise required hereunder, (ii) whether any conditions specified in
          Section 5.3 are then satisfied, (iii) whether a Default or an Event of
          Default then exists, (iv) failure for any such request or deemed
          request for Revolving Loan to be made by the time otherwise required
          hereunder, (v) whether the date of such borrowing is a date on which
          Revolving Loans are otherwise permitted to be made hereunder or (vi)
          any termination of the Commitments relating thereto immediately prior
          to or contemporaneously with such borrowing. In the event that any
          Revolving Loan cannot for any reason be made on the date otherwise
          required above (including, without limitation, as a result of the
          commencement of a proceeding under the Bankruptcy Code with respect to
          the Borrower or any Credit Party), then each such Lender hereby agrees
          that it shall forthwith purchase (as of the date such borrowing would
          otherwise have occurred, but adjusted for any payments received from
          the Borrower on or after such date and prior to such purchase) from
          the Issuing Lender such Participation Interests in the outstanding LOC
          Obligations as shall be necessary to cause each such Lender to share
          in such LOC Obligations ratably (based upon the respective Revolving
          Commitment Percentages of the Lenders (determined before giving effect
          to any termination of the Commitments pursuant to Section 9.2)),
          provided that at the time any purchase of Participation Interests
          pursuant to this sentence is actually made, the purchasing Lender
          shall be required to pay to the Issuing Lender, to the extent not paid
          to the Issuer by the Borrower in accordance with the terms of
          subsection (d) above, interest on the principal amount of
          Participation Interests purchased for each day from and including the
          day upon which such borrowing would otherwise have occurred to but
          excluding the date of payment for such Participation Interests, at the
          rate equal to, if paid within two (2) Business Days of the date of the
          Revolving Loan advance, the Federal Funds Rate, and thereafter at a
          rate equal to the Base Rate.

               (f) Designation of Consolidated Parties as Account Parties.
          Notwithstanding anything to the contrary set forth in this Credit
          Agreement, including without limitation Section 2.2(a), a Letter of
          Credit issued hereunder may contain a statement to the effect that
          such Letter of Credit is issued for the account of a Consolidated
          Party other than the Borrower, provided that notwithstanding such
          statement, the Borrower shall be the actual account party for all
          purposes of this Credit Agreement for such Letter of Credit and such
          statement shall not affect the Borrower's reimbursement obligations
          hereunder with respect to such Letter of Credit.

               (g) Renewal, Extension. The renewal or extension of any Letter of
          Credit shall, for purposes hereof, be treated in all respects the same
          as the issuance of a new Letter of Credit hereunder.

               (h) Uniform Customs and Practices. The Issuing Lender may have
          the Letters of Credit be subject to The Uniform Customs and Practice
          for Documentary Credits, as published as of the date of issue by the
          International Chamber of Commerce (the "UCP"), in which case the UCP
          may be incorporated therein and deemed in all respects to be a part
          thereof.

               (i) Indemnification; Nature of Issuing Lender's Duties.

                    (i) In addition to its other obligations under this Section
               2.2, the Borrower hereby agrees to pay, and protect, indemnify
               and save each Lender harmless from and against, any and all
               claims, demands, liabilities, damages, losses, costs, charges and
               expenses (including reasonable attorneys' fees) that such Lender
               may incur or be subject to as a consequence, direct or indirect,
               of (A) the issuance of any Letter of Credit or (B) the failure of
               such Lender to honor a drawing under a Letter of Credit as a
               result of any act or omission, whether rightful or wrongful, of
               any present or future de jure or de facto government or
               Governmental Authority (all such acts or omissions, herein called
               "Government Acts").

                    (ii) As between the Borrower and the Lenders (including the
               Issuing Lender), the Borrower shall assume all risks of the acts,
               omissions or misuse of any Letter of Credit by the beneficiary
               thereof. No Lender (including the Issuing Lender) shall be
               responsible: (A) for the form, 


                                       26


               validity, sufficiency, accuracy, genuineness or legal effect of
               any document submitted by any party in connection with the
               application for and issuance of any Letter of Credit, even if it
               should in fact prove to be in any or all respects invalid,
               insufficient, inaccurate, fraudulent or forged; (B) for the
               validity or sufficiency of any instrument transferring or
               assigning or purporting to transfer or assign any Letter of
               Credit or the rights or benefits thereunder or proceeds thereof,
               in whole or in part, that may prove to be invalid or ineffective
               for any reason; (C) for errors, omissions, interruptions or
               delays in transmission or delivery of any messages, by mail,
               cable, telegraph, telex or otherwise, whether or not they be in
               cipher; (D) for any loss or delay in the transmission or
               otherwise of any document required in order to make a drawing
               under a Letter of Credit or of the proceeds thereof; and (E) for
               any consequences arising from causes beyond the control of such
               Lender, including, without limitation, any Government Acts. None
               of the above shall affect, impair, or prevent the vesting of the
               Issuing Lender's rights or powers hereunder.

                    (iii) In furtherance and extension and not in limitation of
               the specific provisions hereinabove set forth, any action taken
               or omitted by any Lender (including the Issuing Lender), under or
               in connection with any Letter of Credit or the related
               certificates, if taken or omitted in good faith, shall not put
               such Lender under any resulting liability to the Borrower or any
               other Credit Party. It is the intention of the parties that this
               Credit Agreement shall be construed and applied to protect and
               indemnify each Lender (including the Issuing Lender) against any
               and all risks involved in the issuance of the Letters of Credit,
               all of which risks are hereby assumed by the Borrower (on behalf
               of itself and each of the other Credit Parties), including,
               without limitation, any and all Government Acts. No Lender
               (including the Issuing Lender) shall, in any way, be liable for
               any failure by such Lender or anyone else to pay any drawing
               under any Letter of Credit as a result of any Government Acts or
               any other cause beyond the control of such Lender.

                    (iv) Nothing in this subsection (h) is intended to limit the
               reimbursement obligations of the Borrower contained in subsection
               (d) above. The obligations of the Borrower under this subsection
               (h) shall survive the termination of this Credit Agreement. No
               act or omissions of any current or prior beneficiary of a Letter
               of Credit shall in any way affect or impair the rights of the
               Lenders (including the Issuing Lender) to enforce any right,
               power or benefit under this Credit Agreement.

                    (v) Notwithstanding anything to the contrary contained in
               this subsection (h), the Borrower shall have no obligation to
               indemnify any Lender (including the Issuing Lender) in respect of
               any liability incurred by such Lender (A) arising solely out of
               the gross negligence or willful misconduct of such Lender, as
               determined by a court of competent jurisdiction, or (B) caused by
               such Lender's failure to pay under any Letter of Credit after
               presentation to it of a request strictly complying with the terms
               and conditions of such Letter of Credit, as determined by a court
               of competent jurisdiction, unless such payment is prohibited by
               any law, regulation, court order or decree.

               (j) Responsibility of Issuing Lender. It is expressly understood
          and agreed that the obligations of the Issuing Lender hereunder to the
          Lenders are only those expressly set forth in this Credit Agreement
          and that the Issuing Lender shall be entitled to assume that the
          conditions precedent set forth in Section 5.3 have been satisfied
          unless it shall have acquired actual knowledge that any such condition
          precedent has not been satisfied; provided, however, that nothing set
          forth in this Section 2.2 shall be deemed to prejudice the right of
          any Lender to recover from the Issuing Lender any amounts made
          available by such Lender to the Issuing Lender pursuant to this
          Section 2.2 in the event that it is determined by a court of competent
          jurisdiction that the payment with respect to a Letter of Credit
          constituted gross negligence or willful misconduct on the part of the
          Issuing Lender.

               (k) Conflict with LOC Documents. In the event of any conflict
          between this Credit Agreement and any LOC Document (including any
          letter of credit application), this Credit Agreement shall control.

                                       27


     2.3  Acquisition Loans.

                  (a) Acquisition Loan Commitment. Subject to the terms and
         conditions hereof and in reliance upon the representations and
         warranties set forth herein, each Lender severally agrees to make
         available to the Borrower such Lender's Acquisition Loan Commitment
         Percentage of revolving credit loans requested by the Borrower in
         Dollars ("Acquisition Loans") from time to time from the Amendment No.
         4 Effective Date until June 12, 2000, or such earlier date as the
         Acquisition Loan Commitments shall have been terminated as provided
         herein for the purpose of financing the purchase price of, and fees and
         expenses in connection with, Permitted Acquisitions and capital
         expenditures; provided, however, that the sum of the aggregate
         principal amount of outstanding Acquisition Loans shall not exceed
         SEVENTY-FIVE MILLION DOLLARS ($75,000,000) (as such aggregate maximum
         amount may be reduced or increased from time to time as provided in
         Section 3.4, the "Acquisition Loan Committed Amount"); provided,
         further, (A) with regard to each Lender individually, such Lender's
         outstanding Acquisition Loans shall not exceed such Lender's
         Acquisition Loan Commitment Percentage of the Acquisition Loan
         Committed Amount, and (B) the aggregate principal amount of outstanding
         Acquisition Loans shall not exceed the Acquisition Loan Committed
         Amount. Acquisition Loans may consist of Base Rate Loans or Eurodollar
         Loans, or a combination thereof, as the Borrower may request; provided,
         however, that no more than 16 Eurodollar Loans shall be outstanding
         hereunder at any time. For purposes hereof, Eurodollar Loans with
         different Interest Periods shall be considered as separate Eurodollar
         Loans, even if they begin on the same date, although borrowings,
         extensions and conversions may, in accordance with the provisions
         hereof, be combined at the end of existing Interest Periods to
         constitute a new Eurodollar Loan with a single Interest Period.
         Acquisition Loans, other than any term portion of the Acquisition
         Loans, hereunder may be repaid and reborrowed in accordance with the
         provisions hereof.

               (b) Acquisition Loan Borrowings.

                    (i) Notice of Borrowing. The Borrower shall request an
               Acquisition Loan borrowing by written notice (or telephonic
               notice promptly confirmed in writing) to the Agent not later than
               12:00 Noon (Charlotte, North Carolina time) on the Business Day
               prior to the date of the requested borrowing in the case of Base
               Rate Loans, and on the third Business Day prior to the date of
               the requested borrowing in the case of Eurodollar Loans. Each
               such request for borrowing shall (A) be irrevocable, (B) specify
               (1) that an Acquisition Loan is requested, (2) the date of the
               requested borrowing (which shall be a Business Day), (3) the
               aggregate principal amount to be borrowed, (4) whether the
               borrowing shall be comprised of Base Rate Loans, Eurodollar Loans
               or a combination thereof, and if Eurodollar Loans are requested,
               the Interest Period(s) therefor and (C) be accompanied by a
               certificate of the chief financial of the Borrower describing in
               reasonable detail the Permitted Acquisition to which such
               requested borrowing relates. If the Borrower shall fail to
               specify in any such Notice of Borrowing (I) an applicable
               Interest Period in the case of a Eurodollar Loan, then such
               notice shall be deemed to be a request for an Interest Period of
               one month, or (II) the type of Acquisition Loan requested, then
               such notice shall be deemed to be a request for a Base Rate Loan
               hereunder. The Agent shall give notice to each affected Lender
               promptly upon receipt of each Notice of Borrowing pursuant to
               this Section 2.3(b)(i), the contents thereof and each such
               Lender's share of any borrowing to be made pursuant thereto.

                    (ii) Minimum Amounts. Each Eurodollar Loan or Base Rate Loan
               that is an Acquisition Loan shall be in a minimum aggregate
               principal amount of $1,000,000 and integral multiples of $100,000
               in excess thereof (or the remaining amount of the Acquisition
               Loan Committed Amount, if less).

                    (iii) Advances. Each Lender will make its Acquisition Loan
               Commitment Percentage of each Acquisition Loan borrowing
               available to the Agent for the account of the Borrower as
               specified in Section 3.15(a), or in such other manner as the
               Agent may specify in writing, by 2:00 P.M. (Charlotte, North
               Carolina time) on the date specified in the applicable Notice of
               Borrowing in Dollars and in funds immediately available to the
               Agent. Such borrowing will then be made available to the Borrower
               by the Agent by crediting the account of the Borrower on the
               books of 


                                       28



               such office with the aggregate of the amounts made available to
               the Agent by the Lenders and in like funds as received by the
               Agent.

               (c) Repayment.

                         (i) The principal amount of all Acquisition Loans
                    advanced during the period from the Amendment No. 4
                    Effective Date to and including June 12, 1999 shall be

                    (i) Base Rate Loans. During such periods as Acquisition
               Loans shall be comprised in whole or in part of Base Rate Loans,
               such Base Rate Loans shall bear interest at a per annum rate
               equal to the Adjusted Base Rate.


                                       29



                    (ii) Eurodollar Loans. During such periods as Acquisition
               Loans shall be comprised in whole or in part of Eurodollar Loans,
               such Eurodollar Loans shall bear interest at a per annum rate
               equal to the Adjusted Eurodollar Rate.

          Interest on Acquisition Loans shall be payable in arrears on each
          applicable Interest Payment Date (or at such other times as may be
          specified herein).

                    (e) Acquisition Notes. The Acquisition Loans made by each
               Lender shall be evidenced by a duly executed promissory note of
               the Borrower to such Lender in an original principal amount equal
               to such Lender's Acquisition Loan Commitment Percentage of the
               Acquisition Loan Committed Amount and in substantially the form
               of Exhibit 2.3(e).

     2.4  Tranche A Term Loan.

          (a) Tranche A Term Commitment. Subject to the terms and conditions
     hereof and in reliance upon the representations and warranties set forth
     herein each Lender severally agrees to make available to the Borrower on

     set forth. The Tranche A Term Loan may consist of Base Rate Loans or
     Eurodollar Loans, or a combination thereof, as the Borrower may request;
     provided, however, that no more than 16 Eurodollar Loans shall be
     outstanding hereunder at any time. For purposes hereof, Eurodollar Loans
     with different Interest Periods shall be considered as separate Eurodollar
     Loans, even if they begin on the same date, although borrowings, extensions
     and conversions may, in accordance with the provisions hereof, be combined
     at the end of existing Interest Periods to constitute a new Eurodollar Loan

     3.2  Extension and Conversion.

     Subject to the terms of Section 5.2, the Borrower shall have the option, on
any Business Day, to extend existing Loans into a subsequent permissible
Interest Period or to convert Loans into Loans of another interest rate type;
provided, however, that (i) except as provided in Section 3.8, Eurodollar Loans
may be converted into Base Rate Loans only on the last day of the Interest
Period applicable thereto, (ii) Eurodollar Loans may be extended, and Base Rate
Loans may be converted into Eurodollar Loans, only if no Default or Event of
Default is in existence on the date of extension or conversion, (iii) Loans
extended as, or converted into, Eurodollar Loans shall be subject to the terms
of the definition of "Interest Period" set forth in Section 1.1 and shall be in
such minimum amounts as provided in, with respect to Revolving Loans, Section
2.1(b)(ii), with respect to Acquisition Loans, Section 2.3(b)(ii), or, with
respect to the Tranche A Term Loan, Section 2.4(c), (iv) no more than 16
Eurodollar Loans shall be outstanding hereunder at any time (it being understood
that, for purposes hereof, Eurodollar Loans with different Interest Periods
shall be considered as separate Eurodollar Loans, even if they begin on the same
date, although borrowings, extensions and conversions may, in accordance with
the provisions hereof, be combined at the end of existing Interest Periods to
constitute a new Eurodollar Loan with a single Interest Period) and (v) any
request for extension or conversion of a Eurodollar Loan which shall fail to
specify an Interest Period shall be deemed to be a request for an Interest
Period of one month. Each such extension or conversion shall be effected by the
Borrower by giving a Notice of Extension/Conversion (or telephonic notice
promptly confirmed in writing) to the office of the Agent specified in specified
in Schedule 2.1(a), or at such other office as the Agent may designate in
writing, prior to 12:00 Noon (Charlotte, North Carolina time) on the Business

the date of the proposed extension or conversion, specifying the date of the
proposed extension or conversion, the Loans to be so extended or converted, the
types of Loans into which such Loans are to be converted and, if appropriate,
the applicable Interest Periods with respect thereto. Each request for extension
or conversion shall be irrevocable and shall constitute a representation and
warranty by the Borrower of the matters specified in subsections (b), (c) and
(d) of Section 5.3. In the event the Borrower fails to request extension or
conversion of any Eurodollar Loan in accordance with this Section, or any such
conversion or extension is not permitted or required by this Section, then such
Eurodollar Loan shall be automatically converted into a Base Rate Loan at the
end of the Interest Period applicable thereto. The Agent shall give each Lender
notice as promptly as practicable of any such proposed extension or conversion
affecting any Loan.

     $500,000. Subject to the foregoing terms, amounts prepaid under this
     Section 3.3(a) shall be applied as the Borrower may elect; provided that if
     the Borrower fails to specify a voluntary prepayment then such prepayment
     shall be applied first to Revolving Loans, second to the outstanding
     revolving loan portion of the Acquisition Loans and third pro rata to the
     outstanding term loan portion of the Acquisition Loans and the Tranche A
     Term Loan (in each case ratably to the remaining Principal Amortization

          Issuance (such prepayments shall be applied as set forth in clause
          (vii) below).

               (vi) Acquisition Purchase Price Reductions. Immediately upon
          receipt by a Consolidated Party of proceeds from a post-closing

          equal to 100% of such purchase price reduction (such prepayments shall
          be applied as set forth in clause (vii) below).

     a standby letter of credit fronting fee equal to 0.25% on the average daily
     maximum amount available to be drawn under each such standby Letter of
     Credit (such fee to be payable quarterly in arrears on the last Business
     Day of each March, June, September and December for the immediately
     preceding quarter (or a portion thereof)), (b) a trade letter of credit
     drawing fee equal to 0.25% on the amount of each drawing under any such
     trade Letter of Credit (such fee to be payable on each date of drawing
     under a trade Letter of Credit) and (c) the customary charges from time to
     time of the Issuing Lender with respect to the issuance, amendment,
     transfer, administration, cancellation and conversion of, and drawings
     under, such Letters of Credit (collectively, the "Issuing Lender Fees").

          (c) Administrative Fees. The Borrower agrees to pay to the Agent, for
     its own account and NationsBanc Montgomery Securities, Inc., as applicable,
     the fees referred to in the Agent's Fee Letter (collectively, the "Agent's
     Fees").

     3.6  Capital Adequacy.

     If any Lender has determined, after the date hereof, that the adoption or
the becoming effective of, or any change in, or any change by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof in the interpretation or administration of, any
applicable law, rule or regulation regarding capital adequacy, or compliance by
such Lender with any request or directive regarding capital adequacy (whether or
not having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on such
Lender's capital or assets as a consequence of its commitments or obligations
hereunder to a level below that which such Lender could have achieved but for
such adoption, effectiveness, change or compliance (taking into consideration
such Lender's policies with respect to capital adequacy), then, upon notice from
such Lender to the Borrower, the Borrower shall be obligated to pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction. Any Lender claiming compensation under this Section 3.6 shall furnish
to the Borrower and the Agent a statement setting forth in reasonable detail the
additional amount or amounts payable to it hereunder and the calculations used
to determine such amount or amounts, which statement shall be conclusive and
binding on the parties hereto in the absence of manifest error. In determining
such amount, such Lender may use any reasonable averaging and attribution
methods.

     3.7  Limitation on Eurodollar Loans.

     If on or prior to the first day of any Interest Period for any Eurodollar
Loan:

          (a) the Agent determines (which determination shall be conclusive)
     that by reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Eurodollar Rate for such
     Interest Period; or

          (b) the Required Lenders determine (which determination shall be
     conclusive) and notify the Agent that the Eurodollar Rate will not
     adequately and fairly reflect the cost to the Lenders of funding Eurodollar
     Loans for such Interest Period;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans, Continue Eurodollar Loans, or to Convert Base
Rate Loans into Eurodollar Loans and the Borrower shall, on the last day(s) of
the then current Interest Period(s) for the outstanding Eurodollar Loans, either
prepay such Eurodollar Loans or Convert such Eurodollar Loans into Base Rate
Loans in accordance with the terms of this Credit Agreement.




                                       36


     3.8  Illegality.

     Notwithstanding any other provision of this Credit Agreement, in the event
that it becomes unlawful for any Lender or its Applicable Lending Office to
make, maintain, or fund Eurodollar Loans hereunder, then such Lender shall
promptly notify the Borrower thereof and such Lender's obligation to make or
Continue Eurodollar Loans and to Convert Base Rate Loans into Eurodollar Loans
shall be suspended until such time as such Lender may again make, maintain, and
fund Eurodollar Loans (in which case the provisions of Section 3.10 shall be
applicable).

     3.9  Requirements of Law.

     (a) If, after the date hereof, the adoption of any applicable law, rule, or
regulation, or any change in any applicable law, rule, or regulation, 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 its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such Governmental Authority, central bank, or comparable agency:

          (i) shall subject such Lender (or its Applicable Lending Office) to
     any tax, duty, or other charge with respect to any Eurodollar Loans, its
     Notes, or its obligation to make Eurodollar Loans, or change the basis of
     taxation of any amounts payable to such Lender (or its Applicable Lending
     Office) under this Credit Agreement or its Notes in respect of any
     Eurodollar Loans (other than taxes imposed on the overall net income of
     such Lender by the jurisdiction in which such Lender has its principal
     office or such Applicable Lending Office);

          (ii) shall impose, modify, or deem applicable any reserve, special
     deposit, assessment, or similar requirement (other than the Eurodollar
     Reserve Requirement utilized in the determination of the Adjusted
     Eurodollar Rate) relating to any extensions of credit or other assets of,
     or any deposits with or other liabilities or commitments of, such Lender
     (or its Applicable Lending Office), including the Commitment of such Lender
     hereunder; or

          (iii) shall impose on such Lender (or its Applicable Lending Office)
     or on the United States market for certificates of deposit or the London
     interbank market any other condition affecting this Credit Agreement or its
     Notes or any of such extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, Converting into, Continuing, or
maintaining any Eurodollar Loans or to reduce any sum received or receivable by
such Lender (or its Applicable Lending Office) under this Credit Agreement or
its Notes with respect to any Eurodollar Loans, then the Borrower shall pay to
such Lender on demand such amount or amounts as will compensate such Lender for
such increased cost or reduction. If any Lender requests compensation by the
Borrower under this Section 3.9(a), the Borrower may, by notice to such Lender
(with a copy to the Agent), suspend the obligation of such Lender to make or
Continue Eurodollar Loans, or to Convert Base Rate Loans into Eurodollar Loans,
until the event or condition giving rise to such request ceases to be in effect
(in which case the provisions of Section 3.10 shall be applicable); provided
that such suspension shall not affect the right of such Lender to receive the
compensation so requested.

     (b) Each Lender shall promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such Lender to compensation pursuant to this Section 3.9 and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming
compensation under this Section 3.9 shall furnish to the Borrower and the Agent
a statement setting forth in reasonable detail the additional amount or amounts
payable to it hereunder and the calculations used to determine such amount or
amounts, which statement shall be conclusive and binding on the parties hereto
in the absence of manifest error. In determining such amount, such Lender may
use any reasonable averaging and attribution methods.



                                       37


     3.10 Treatment of Affected Loans.

     If the obligation of any Lender to make any Eurodollar Loan or to Continue,
or to Convert Base Rate Loans into, Eurodollar Loans shall be suspended pursuant
to Section 3.8 or 3.9 hereof, such Lender's Eurodollar Loans shall be
automatically Converted into Base Rate Loans on the last day(s) of the then
current Interest Period(s) for such Eurodollar Loans (or, in the case of a
Conversion required by Section 3.8 hereof, on such earlier date as such Lender
may specify to the Borrower with a copy to the Agent) and, unless and until such
Lender gives notice as provided below that the circumstances specified in
Section 3.8 or 3.9 hereof that gave rise to such Conversion no longer exist:

          (a) to the extent that such Lender's Eurodollar Loans have been so
     Converted, all payments and prepayments of principal that would otherwise
     be applied to such Lender's Eurodollar Loans shall be applied instead to
     its Base Rate Loans; and

          (b) all Loans that would otherwise be made or Continued by such Lender
     as Eurodollar Loans shall be made or Continued instead as Base Rate Loans,
     and all Base Rate Loans of such Lender that would otherwise be Converted
     into Eurodollar Loans shall remain as Base Rate Loans.

If such Lender gives notice to the Borrower (with a copy to the Agent) that the
circumstances specified in Section 3.8 or 3.9 hereof that gave rise to the
Conversion of such Lender's Eurodollar Loans pursuant to this Section 3.10 no
longer exist (which such Lender agrees to do promptly upon such circumstances
ceasing to exist) at a time when Eurodollar Loans made by other Lenders are
outstanding, such Lender's Base Rate Loans shall be automatically Converted, on
the first day(s) of the next succeeding Interest Period(s) for such outstanding
Eurodollar Loans, to the extent necessary so that, after giving effect thereto,
all Loans held by the Lenders holding Eurodollar Loans and by such Lender are
held pro rata (as to principal amounts, interest rate basis, and Interest
Periods) in accordance with their respective Commitments.

     3.11 Taxes.

          (a) Any and all payments by the Borrower to or for the account of any
     Lender or the Agent hereunder or under any other Credit Document shall be
     made free and clear of and without deduction for any and all present or
     future taxes, duties, levies, imposts, deductions, charges or withholdings,
     and all liabilities with respect thereto, excluding, in the case of each
     Lender and the Agent, taxes imposed on its income, and franchise taxes
     imposed on it, by the jurisdiction under the laws of which such Lender (or
     its Applicable Lending Office) or the Agent (as the case may be) is
     organized or any political subdivision thereof (all such non-excluded
     taxes, duties, 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 under this Credit Agreement or any other Credit Document to any
     Lender or the Agent, (i) the sum payable shall be increased as necessary so
     that after making all required deductions (including deductions applicable
     to additional sums payable under this Section 3.11) such Lender or the
     Agent receives an amount equal to the sum it would have received had no
     such deductions been made, (ii) the Borrower shall make such deductions,
     (iii) the Borrower shall pay the full amount deducted to the relevant
     taxation authority or other authority in accordance with applicable law,
     and (iv) the Borrower shall furnish to the Agent, at its address referred
     to in Section 11.1, the original or a certified copy of a receipt
     evidencing payment thereof.

          (b) In addition, the Borrower agrees to pay any and all present or
     future stamp or documentary taxes and any other excise or property taxes or
     charges or similar levies which arise from any payment made under this
     Credit Agreement or any other Credit Document or from the execution or
     delivery of, or otherwise with respect to, this Credit Agreement or any
     other Credit Document (hereinafter referred to as "Other Taxes").

          (c) The Borrower agrees to indemnify each Lender and the Agent for the
     full amount of Taxes and Other Taxes (including, without limitation, any
     Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts
     payable under this Section 3.11) 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.



                                       38


          (d) Each Lender organized under the laws of a jurisdiction outside the
     United States, on or prior to the date of its execution and delivery of
     this Credit Agreement in the case of each Lender listed on the signature
     pages hereof and on or prior to the date on which it becomes a Lender in
     the case of each other Lender, and from time to time thereafter if
     requested in writing by the Borrower or the Agent (but only so long as such
     Lender remains lawfully able to do so), shall provide the Borrower and the
     Agent with (i) Internal Revenue Service Form 1001 or 4224, as appropriate,
     or any successor form prescribed by the Internal Revenue Service,
     certifying that such Lender is entitled to benefits under an income tax
     treaty to which the United States is a party which reduces the rate of
     withholding tax on payments of interest or certifying that the income
     receivable pursuant to this Credit Agreement is effectively connected with
     the conduct of a trade or business in the United States, (ii) Internal
     Revenue Service Form W-8 or W-9, as appropriate, or any successor form
     prescribed by the Internal Revenue Service, and/or (iii) any other form or
     certificate required by any taxing authority (including any certificate
     required by Sections 871(h) and 881(c) of the Internal Revenue Code),
     certifying that such Lender is entitled to an exemption from or a reduced
     rate of tax on payments pursuant to this Credit Agreement or any of the
     other Credit Documents.

          (e) For any period with respect to which a Lender has failed to
     provide the Borrower and the Agent with the appropriate form pursuant to
     Section 3.11(d) (unless such failure is due to a change in treaty, law, or
     regulation occurring subsequent to the date on which a form originally was
     required to be provided), such Lender shall not be entitled to
     indemnification under Section 3.11(a) or 3.11(b) with respect to Taxes
     imposed by the United States; provided, however, that should a Lender,
     which is otherwise exempt from or subject to a reduced rate of withholding
     tax, become subject to Taxes because of its failure to deliver a form
     required hereunder, the Borrower shall take such steps as such Lender shall
     reasonably request to assist such Lender to recover such Taxes.

          (f) If the Borrower is required to pay additional amounts to or for
     the account of any Lender pursuant to this Section 3.11, then such Lender
     will agree to use reasonable efforts to change the jurisdiction of its
     Applicable Lending Office so as to eliminate or reduce any such additional
     payment which may thereafter accrue if such change, in the judgment of such
     Lender, is not otherwise disadvantageous to such Lender.

          (g) Within thirty (30) days after the date of any payment of Taxes,
     the Borrower shall furnish to the Agent the original or a certified copy of
     a receipt evidencing such payment.

          (h) Any Lender claiming compensation under this Section 3.11 shall
     furnish to the Borrower and the Agent a statement setting forth in
     reasonable detail the additional amount or amounts payable to it hereunder
     and the calculations used to determine such amount or amounts, which
     statement shall be conclusive and binding on the parties hereto in the
     absence of manifest error.

          (i) Without prejudice to the survival of any other agreement of the
     Borrower hereunder, the agreements and obligations of the Borrower
     contained in this Section 3.11 shall survive the repayment of the Loans,
     LOC Obligations and other obligations under the Credit Documents and the
     termination of the Commitments hereunder.

     3.12 Compensation.

     Upon the request of any Lender, the Borrower shall pay to such Lender such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense (including loss of
anticipated profits) incurred by it as a result of:

          (a) any payment, prepayment, or Conversion of a Eurodollar Loan for
     any reason (including, without limitation, the acceleration of the Loans
     pursuant to Section 9.2) on a date other than the last day of the Interest
     Period for such Loan; or

          (b) any failure by the Borrower for any reason (including, without
     limitation, the failure of any condition precedent specified in Section 5
     to be satisfied) to borrow, Convert, Continue, or prepay a 



                                       39


     Eurodollar Loan on the date for such borrowing, Conversion, Continuation,
     or prepayment specified in the relevant notice of borrowing, prepayment,
     Continuation, or Conversion under this Credit Agreement.

With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of the applicable Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Eurodollar Loans provided for herein (excluding,
however, the Applicable Percentage included therein, if any) over (b) the amount
of interest (as reasonably determined by such Lender) which would have accrued
to such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market. The covenants of
the Borrower set forth in this Section 3.12 shall survive the repayment of the
Loans, LOC Obligations and other obligations under the Credit Documents and the
termination of the Commitments hereunder.

     3.13 Pro Rata Treatment.

     Except to the extent otherwise provided herein:

          (a) Loans. Each Loan, each payment or (subject to the terms of Section
     3.3) prepayment of principal of any Loan or reimbursement obligations
     arising from drawings under Letters of Credit, each payment of interest on
     the Loans or reimbursement obligations arising from drawings under Letters
     of Credit, each payment of Revolving Unused Fees, each payment of
     Acquisition Loan Unused Fees, each payment of the Standby Letter of Credit
     Fee, each payment of the Trade Letter of Credit Fee, each reduction of the
     Revolving Committed Amount and each conversion or extension of any Loan,
     shall be allocated pro rata among the Lenders in accordance with the
     respective principal amounts of their outstanding Loans and Participation
     Interests.

          (b) Advances. No Lender shall be responsible for the failure or delay
     by any other Lender in its obligation to make its ratable share of a
     borrowing hereunder; provided, however, that the failure of any Lender to
     fulfill its obligations hereunder shall not relieve any other Lender of its
     obligations hereunder. Unless the Agent shall have been notified by any
     Lender prior to the date of any requested borrowing that such Lender does
     not intend to make available to the Agent its ratable share of such
     borrowing to be made on such date, the Agent may assume that such Lender
     has made such amount available to the Agent on the date of such borrowing,
     and the Agent in reliance upon such assumption, may (in its sole discretion
     but without any obligation to do so) make available to the Borrower a
     corresponding amount. If such corresponding amount is not in fact made
     available to the Agent, the Agent shall be able to recover such
     corresponding amount from such Lender. If such Lender does not pay such
     corresponding amount forthwith upon the Agent's demand therefor, the Agent
     will promptly notify the Borrower, and the Borrower shall immediately pay
     such corresponding amount to the Agent. The Agent shall also be entitled to
     recover from the Lender or the Borrower, as the case may be, interest on
     such corresponding amount in respect of each day from the date such
     corresponding amount was made available by the Agent to the Borrower to the
     date such corresponding amount is recovered by the Agent at a per annum
     rate equal to (i) from the Borrower at the applicable rate for the
     applicable borrowing pursuant to the Notice of Borrowing and (ii) from a
     Lender at the Federal Funds Rate. Nothing contained in this Section 3.13(b)
     shall be deemed to constitute a waiver by the Borrower of its rights in
     respect of any claim for breach of contract relating to the wrongful
     failure (as determined by a court of competent jurisdiction) of any Lender
     to make any Loan on the date of the requested borrowing.

     3.14 Sharing of Payments.

     The Lenders agree among themselves that, in the event that any Lender shall
obtain payment in respect of any Loan, LOC Obligations or any other obligation
owing to such Lender under this Credit Agreement through the exercise of a right
of setoff, banker's lien or counterclaim, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, or by
any other means, in excess of its pro rata share of such payment as provided for
in this Credit Agreement, such Lender shall promptly purchase from the other
Lenders a Participation Interest in such Loans, LOC Obligations and other
obligations in such amounts, and make 



                                       40




such other adjustments from time to time, as shall be equitable to the end that
all Lenders share such payment in accordance with their respective ratable
shares as provided for in this Credit Agreement. The Lenders further agree among
themselves that if payment to a Lender obtained by such Lender through the
exercise of a right of setoff, banker's lien, counterclaim or other event as
aforesaid shall be rescinded or must otherwise be restored, each Lender which
shall have shared the benefit of such payment shall, by repurchase of a
Participation Interest theretofore sold, return its share of that benefit
(together with its share of any accrued interest payable with respect thereto)
to each Lender whose payment shall have been rescinded or otherwise restored.
The Borrower agrees that any Lender so purchasing such a Participation Interest
may, to the fullest extent permitted by law, exercise all rights of payment,
including setoff, banker's lien or counterclaim, with respect to such
Participation Interest as fully as if such Lender were a holder of such Loan,
LOC Obligations or other obligation in the amount of such Participation
Interest. Except as otherwise expressly provided in this Credit Agreement, if
any Lender or the Agent shall fail to remit to the Agent or any other Lender an
amount payable by such Lender or the Agent to the Agent or such other Lender
pursuant to this Credit Agreement on the date when such amount is due, such
payments shall be made together with interest thereon for each date from the
date such amount is due until the date such amount is paid to the Agent or such
other Lender at a rate per annum equal to the Federal Funds Rate. If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section 3.14 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
Section 3.14 to share in the benefits of any recovery on such secured claim.

     3.15 Payments, Computations, Etc.

          (a) Except as otherwise specifically provided herein, all payments
     hereunder shall be made to the Agent in dollars in immediately available
     funds, without setoff, deduction, counterclaim or withholding of any kind,
     at the Agent's office specified in Schedule 2.1(a) not later than 2:00 P.M.
     (Charlotte, North Carolina time) on the date when due. Payments received
     after such time shall be deemed to have been received on the next
     succeeding Business Day. The Agent may (but shall not be obligated to)
     debit the amount of any such payment which is not made by such time to any
     ordinary deposit account of the Borrower maintained with the Agent (with
     notice to the Borrower). The Borrower shall, at the time it makes any
     payment under this Credit Agreement, specify to the Agent the Loans, LOC
     Obligations, Fees, interest or other amounts payable by the Borrower
     hereunder to which such payment is to be applied (and in the event that it
     fails so to specify, or if such application would be inconsistent with the
     terms hereof, the Agent shall distribute such payment to the Lenders in
     such manner as the Agent may determine to be appropriate in respect of
     obligations owing by the Borrower hereunder, subject to the terms of
     Section 3.13(a)). The Agent will distribute such payments to such Lenders,
     if any such payment is received prior to 12:00 Noon (Charlotte, North
     Carolina time) on a Business Day in like funds as received prior to the end
     of such Business Day and otherwise the Agent will distribute such payment
     to such Lenders on the next succeeding Business Day. Whenever any payment
     hereunder shall be stated to be due on a day which is not a Business Day,
     the due date thereof shall be extended to the next succeeding Business Day
     (subject to accrual of interest and Fees for the period of such extension),
     except that in the case of Eurodollar Loans, if the extension would cause
     the payment to be made in the next following calendar month, then such
     payment shall instead be made on the next preceding Business Day. Except as
     expressly provided otherwise herein, all computations of interest and fees
     shall be made on the basis of actual number of days elapsed over a year of
     360 days, except with respect to computation of interest on Base Rate Loans
     which (unless the Base Rate is determined by reference to the Federal Funds
     Rate) shall be calculated based on a year of 365 or 366 days, as
     appropriate. Interest shall accrue from and include the date of borrowing,
     but exclude the date of payment.

          (b) Allocation of Payments After Event of Default. Notwithstanding any
     other provisions of this Credit Agreement to the contrary, after the
     occurrence and during the continuance of an Event of Default, all amounts
     collected or received by the Agent or any Lender on account of the Credit
     Party Obligations or any other amounts outstanding under any of the Credit
     Documents or in respect of the Collateral shall be paid over or delivered
     as follows:

          FIRST, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation reasonable attorneys' fees) of the
     Agent in connection with enforcing the rights of the Lenders under the
     Credit Documents and any protective advances made by the Agent with respect
     to the Collateral under or pursuant to the terms of the Collateral
     Documents;





                                       41


          SECOND, to payment of any fees owed to the Agent;

          THIRD, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation, reasonable attorneys' fees) of each
     of the Lenders in connection with enforcing its rights under the Credit
     Documents or otherwise with respect to the Credit Party Obligations owing
     to such Lender;

          FOURTH, to the payment of all of the Credit Party Obligations
     consisting of accrued fees and interest;

          FIFTH, to the payment of the outstanding principal amount of the
     Credit Party Obligations (including the payment or cash collateralization
     of the outstanding LOC Obligations);

          SIXTH, to all other Credit Party Obligations and other obligations
     which shall have become due and payable under the Credit Documents or
     otherwise and not repaid pursuant to clauses "FIRST" through "FIFTH" above;
     and

          SEVENTH, to the payment of the surplus, if any, to whoever may be
     lawfully entitled to receive such surplus.

     In carrying out the foregoing, (i) amounts received shall be applied in the
     numerical order provided until exhausted prior to application to the next
     succeeding category; (ii) each of the Lenders shall receive an amount equal
     to its pro rata share (based on the proportion that the then outstanding
     Loans and LOC Obligations held by such Lender bears to the aggregate then
     outstanding Loans and LOC Obligations) of amounts available to be applied
     pursuant to clauses "THIRD", "FOURTH", "FIFTH" and "SIXTH" above; and (iii)
     to the extent that any amounts available for distribution pursuant to
     clause "FIFTH" above are attributable to the issued but undrawn amount of
     outstanding Letters of Credit, such amounts shall be held by the Agent in a
     cash collateral account and applied (A) first, to reimburse the Issuing
     Lender from time to time for any drawings under such Letters of Credit and
     (B) then, following the expiration of all Letters of Credit, to all other
     obligations of the types described in clauses "FIFTH" and "SIXTH" above in
     the manner provided in this Section 3.15(b).

     3.16 Evidence of Debt.

          (a) Each Lender shall maintain an account or accounts evidencing each
     Loan made by such Lender to the Borrower from time to time, including the
     amounts of principal and interest payable and paid to such Lender from time
     to time under this Credit Agreement. Each Lender will make reasonable
     efforts to maintain the accuracy of its account or accounts and to promptly
     update its account or accounts from time to time, as necessary.

          (b) The Agent shall maintain the Register pursuant to Section 11.3(c),
     and a subaccount for each Lender, in which Register and subaccounts (taken
     together) shall be recorded (i) the amount, type and Interest Period of
     each such Loan hereunder, (ii) the amount of any principal or interest due
     and payable or to become due and payable to each Lender hereunder and (iii)
     the amount of any sum received by the Agent hereunder from or for the
     account of the Borrower and each Lender's share thereof. The Agent will
     make reasonable efforts to maintain the accuracy of the subaccounts
     referred to in the preceding sentence and to promptly update such
     subaccounts from time to time, as necessary.

          (c) The entries made in the accounts, Register and subaccounts
     maintained pursuant to subsection (b) of this Section 3.16 (and, if
     consistent with the entries of the Agent, subsection (a)) shall be prima
     facie evidence of the existence and amounts of the obligations of the
     Borrower therein recorded; provided, however, that the failure of any
     Lender or the Agent to maintain any such account, such Register or such
     subaccount, as applicable, or any error therein, shall not in any manner
     affect the obligation of the Borrower to repay the Loans made by such
     Lender in accordance with the terms hereof.




                                       42



     3.17 Mandatory Assignment.

     In the event that any Lender delivers to the Borrower, a demand for payment
in accordance with Section 3.6, 3.9 or 3.11 then, provided that no Default or
Event of Default has occurred and is continuing at such time, the Borrower may,
at its own expense (such expense to include the administrative fee payable to
the Agent under Section 11.3(b)), and with the consent of the Agent (such
consent not to be unreasonably withheld), require such Lender to transfer and
assign in whole, without recourse (in accordance with and subject to the terms
and conditions of Section 11.3), all of its interests, rights and obligations
under this Credit Agreement to an Eligible Assignee which shall assume such
assigned obligations; provided that (i) such assignment shall not conflict with
any law, rule or regulation or order of any court or any Governmental Authority
and (ii) the Borrower or such assignee shall have paid to the assigning Lender
in immediately available funds the principal of and interest accrued to the date
of such payment on the Loans made by it hereunder and all other amounts owed to
it hereunder.

                                                     SECTION 4

                                    GUARANTY

     4.1  The Guaranty.

     Each of the Guarantors hereby jointly and severally guarantees to each
Lender, each Affiliate of a Lender that enters into a Hedging Agreement, and the
Agent as hereinafter provided the prompt payment of the Credit Party Obligations
in full when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) strictly in
accordance with the terms thereof. The Guarantors hereby further agree that if
any of the Credit Party Obligations are not paid in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash
collateralization or otherwise), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Credit Party
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration, as a mandatory
cash collateralization or otherwise) in accordance with the terms of such
extension or renewal.

     Notwithstanding any provision to the contrary contained herein or in any
other of the Credit Documents or Hedging Agreements, the obligations of each
Guarantor hereunder shall be limited to an aggregate amount equal to the largest
amount that would not render its obligations hereunder subject to avoidance
under Section 548 of the Bankruptcy Code or any comparable provisions of any
applicable state law.

     4.2  Obligations Unconditional.

     The obligations of the Guarantors under Section 4.1 are joint and several,
absolute and unconditional, irrespective of the value, genuineness, validity,
regularity or enforceability of any of the Credit Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, release, impairment or exchange of any other guarantee of or
security for any of the Credit Party Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
which might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this Section 4.2 that the
obligations of the Guarantors hereunder shall be absolute and unconditional
under any and all circumstances. Each Guarantor agrees that such Guarantor shall
have no right of subrogation, indemnity, reimbursement or contribution against
the Borrower or any other Guarantor of the Credit Party Obligations for amounts
paid under this Section 4 until such time as the Lenders (and any Affiliates of
Lenders entering into Hedging Agreements) have been paid in full, all
Commitments under this Credit Agreement have been terminated and no Person or
Governmental Authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received under
the Credit Documents or Hedging Agreements. Without limiting the generality of
the foregoing, it is agreed that, to the fullest extent permitted by law, the
occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder which shall remain absolute and
unconditional as described above:

          (a) at any time or from time to time, without notice to any Guarantor,
     the time for any performance of or compliance with any of the Credit Party
     Obligations shall be extended, or such performance or compliance shall be
     waived;



                                       43



          (b) any of the acts mentioned in any of the provisions of any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be done or omitted;

          (c) the maturity of any of the Credit Party Obligations shall be
     accelerated, or any of the Credit Party Obligations shall be modified,
     supplemented or amended in any respect, or any right under any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be waived or any other guarantee of any of the Credit Party Obligations or
     any security therefor shall be released, impaired or exchanged in whole or
     in part or otherwise dealt with;

          (d) any Lien granted to, or in favor of, the Agent or any Lender or
     Lenders as security for any of the Credit Party Obligations shall fail to
     attach or be perfected; or

          (e) any of the Credit Party Obligations shall be determined to be void
     or voidable (including, without limitation, for the benefit of any creditor
     of any Guarantor) or shall be subordinated to the claims of any Person
     (including, without limitation, any creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Agent or any Lender exhaust any right,
power or remedy or proceed against any Person under any of the Credit Documents,
any Hedging Agreement or any other agreement or instrument referred to in the
Credit Documents or Hedging Agreements, or against any other Person under any
other guarantee of, or security for, any of the Credit Party Obligations.

     4.3  Reinstatement.

     The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Credit Party Obligations is
rescinded or must be otherwise restored by any holder of any of the Credit Party
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Agent and each Lender on demand for all reasonable costs and expenses
(including, without limitation, fees and expenses of counsel) incurred by the
Agent or such Lender in connection with such rescission or restoration,
including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or
similar payment under any bankruptcy, insolvency or similar law.

     4.4  Certain Additional Waivers.

     Without limiting the generality of the provisions of this Section 4, each
Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. Sections
26-7 through 26-9, inclusive, to the extent applicable. Each Guarantor further
agrees that such Guarantor shall have no right of recourse to security for the
Credit Party Obligations, except through the exercise of rights of subrogation
pursuant to Section 4.2 and through the exercise of rights of contribution
pursuant to Section 4.6.

     4.5  Remedies.

     The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Agent and the Lenders, on the
other hand, the Credit Party Obligations may be declared to be forthwith due and
payable as provided in Section 9.2 (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section 9.2)
for purposes of Section 4.1 notwithstanding any stay, injunction or other
prohibition preventing such declaration (or preventing the Credit Party
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or the Credit Party
Obligations being deemed to have become automatically due and payable), the
Credit Party Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of Section
4.1. The Guarantors acknowledge and agree that their obligations hereunder are
secured in accordance with the terms of the 


                                       44


Security Agreements and the other Collateral Documents and that the Lenders may
exercise their remedies thereunder in accordance with the terms thereof.

     4.6  Rights of Contribution.

     The Guarantors hereby agree as among themselves that, if any Guarantor
shall make an Excess Payment (as defined below), such Guarantor shall have a
right of contribution from each other Guarantor in an amount equal to such other
Guarantor's Contribution Share (as defined below) of such Excess Payment. The
payment obligations of any Guarantor under this Section 4.6 shall be subordinate
and subject in right of payment to the prior payment in full to the Agent and
the Lenders of the Guaranteed Obligations, and none of the Guarantors shall
exercise any right or remedy under this Section 4.6 against any other Guarantor
until payment and satisfaction in full of all of such Guaranteed Obligations.
For purposes of this Section 4.6, (a) "Guaranteed Obligations" shall mean any
obligations arising under the other provisions of this Section 4; (b) "Excess
Payment" shall mean the amount paid by any Guarantor in excess of its Pro Rata
Share of any Guaranteed Obligations; (c) "Pro Rata Share" shall mean, for any
Guarantor in respect of any payment of Guaranteed Obligations, the ratio
(expressed as a percentage) as of the date of such payment of Guaranteed
Obligations of (i) the amount by which the aggregate present fair salable value
of all of its assets and properties exceeds the amount of all debts and
liabilities of such Guarantor (including contingent, subordinated, unmatured,
and unliquidated liabilities, but excluding the obligations of such Guarantor
hereunder) to (ii) the amount by which the aggregate present fair salable value
of all assets and other properties of the Borrower and all of the Guarantors
exceeds the amount of all of the debts and liabilities (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the
obligations of the Borrower and the Guarantors hereunder) of the Borrower and
all of the Guarantors; provided, however, that, for purposes of calculating the
Pro Rata Shares of the Guarantors in respect of any payment of Guaranteed
Obligations, any Guarantor that became a Guarantor subsequent to the date of any
such payment shall be deemed to have been a Guarantor on the date of such
payment and the financial information for such Guarantor as of the date such
Guarantor became a Guarantor shall be utilized for such Guarantor in connection
with such payment; and (d) "Contribution Share" shall mean, for any Guarantor in
respect of any Excess Payment made by any other Guarantor, the ratio (expressed
as a percentage) as of the date of such Excess Payment of (i) the amount by
which the aggregate present fair salable value of all of its assets and
properties exceeds the amount of all debts and liabilities of such Guarantor
(including contingent, subordinated, unmatured, and unliquidated liabilities,
but excluding the obligations of such Guarantor hereunder) to (ii) the amount by
which the aggregate present fair salable value of all assets and other
properties of the Borrower and all of the Guarantors other than the maker of
such Excess Payment exceeds the amount of all of the debts and liabilities
(including contingent, subordinated, unmatured, and unliquidated liabilities,
but excluding the obligations of the Borrower and the Guarantors hereunder) of
the Borrower and all of the Guarantors other than the maker of such Excess
Payment; provided, however, that, for purposes of calculating the Contribution
Shares of the Guarantors in respect of any Excess Payment, any Guarantor that
became a Guarantor subsequent to the date of any such Excess Payment shall be
deemed to have been a Guarantor on the date of such Excess Payment and the
financial information for such Guarantor as of the date such Guarantor became a
Guarantor shall be utilized for such Guarantor in connection with such Excess
Payment. This Section 4.6 shall not be deemed to affect any right of
subrogation, indemnity, reimbursement or contribution that any Guarantor may
have under applicable law against the Borrower in respect of any payment of
Guaranteed Obligations. Notwithstanding the foregoing, all rights of
contribution against any Guarantor shall terminate from and after such time, if
ever, that such Guarantor shall be relieved of its obligations pursuant to
Section 8.4.

     4.7  Continuing Guarantee.

     The guarantee in this Section 4 is a continuing guarantee, and shall apply
to all Credit Party Obligations whenever arising.

                         REPRESENTATIONS AND WARRANTIES

     The Credit Parties hereby represent to the Agent and each Lender that:

     6.1  Financial Condition.

          (a) The audited consolidated balance sheet of the Consolidated Parties
     as of June 30, 1997 and the audited consolidated statements of earnings and
     statements of cash flows for the year ended June 30, 1996 have heretofore
     been furnished to the Agent. Such audited financial statements (including
     the notes thereto) (i) have been audited by Arthur Andersen, (ii) have been
     prepared in accordance with GAAP consistently, applied throughout the
     periods covered thereby and (iii) present fairly (on the basis disclosed in
     the footnotes to such financial statements) the consolidated financial
     condition, results of operations and cash flows of the Consolidated Parties
     as of such date and for such period. The unaudited interim balance sheets
     of the Consolidated Parties as at the end of, and the related unaudited
     interim statements of earnings and of cash flows for, each fiscal month and
     quarterly period ended after June 30, 1997 and prior to the Amendment No. 4
     Effective Date have heretofore been furnished to the Agent. Such unaudited
     interim financial statements for each such quarterly period, (i) have been
     prepared by independent certified public accountants in accordance with
     GAAP consistently applied throughout the periods covered thereby, subject
     to audit, normal year-end adjustments and the absence of notes and (ii)
     present fairly (on the basis disclosed in the footnotes to such financial
     statements) the consolidated financial condition, results of operations and
     cash flows of the Consolidated Parties as of such date and for such
     periods.

          (b) The pro forma consolidated balance sheet, statement of earnings
     and statement of cash flow of the Consolidated Parties for the two most
     recent fiscal years preceding the Closing Date prepared by Arthur Andersen
     in accordance with GAAP consistently applied throughout the periods covered
     thereby, have heretofore been furnished to the Agent. Such pro forma
     balance sheet is based upon reasonable assumptions and upon information not
     known to be incorrect or misleading in any material respect.

          (c) Except as otherwise disclosed in Schedule 6.1(c), the financial
     statements delivered to the Lenders pursuant to Section 7.1(a) and (b), (i)
     have been prepared in accordance with GAAP (except as may otherwise be
     permitted under Section 7.1(a) and (b)) and (ii) present fairly (on the
     basis disclosed in the footnotes to such financial statements) the
     consolidated financial condition, results of operations and cash flows of
     the Consolidated Parties as of such date and for such periods.

     6.2  No Material Change.

     Since the later of (i) June 30, 1997 and (ii) the then most recent fiscal
year end with respect to which the Agent has received the Required Financial
Information, (a) there has been no Material Adverse Effect and (b) except as
otherwise permitted under this Credit Agreement, no dividends or other
distributions have been declared, paid or made upon the Capital Stock in a
Consolidated Party nor has any of the Capital Stock in a Consolidated Party been
redeemed, retired, purchased or otherwise acquired for value.

     6.3  Organization and Good Standing.

     Each of the Consolidated Parties (a) is duly organized, validly existing
and is in good standing under the laws of the jurisdiction of its incorporation
or organization, (b) has the corporate or other necessary power and authority,
and the legal right, to own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it is currently engaged
and (c) is duly qualified as a foreign entity and in good standing under the
laws of each jurisdiction where its ownership, lease or operation of property or
the conduct of its business requires such qualification, other than in such
jurisdictions where the failure to be so qualified and in good standing could
reasonably be expected to have a Material Adverse Effect.




                                       48


     6.4  Power; Authorization; Enforceable Obligations.

     Each of the Credit Parties has the corporate or other necessary power and
authority, and the legal right, to make, deliver and perform the Credit
Documents to which it is a party, and in the case of the Borrower, to obtain
extensions of credit hereunder, and has taken all necessary corporate action to
authorize the borrowings and other extensions of credit on the terms and
conditions of this Credit Agreement and to authorize the execution, delivery and
performance of the Credit Documents to which it is a party. No material consent
or authorization of, filing with, notice to or other similar act by or in
respect of, any Governmental Authority or any other Person is required to be
obtained or made by or on behalf of any Credit Party in connection with the
borrowings or other extensions of credit hereunder or with the execution,
delivery, performance, validity or enforceability of the Credit Documents to
which such Credit Party is a party, except for (i) consents, authorizations,
notices and filings described in Schedule 6.4, all of which have been obtained
or made or have the status described in such Schedule 6.4 and (ii) filings to
perfect the Liens created by the Collateral Documents. This Credit Agreement has
been, and each other Credit Document to which any Credit Party is a party will
be, duly executed and delivered on behalf of the Credit Parties. This Credit
Agreement constitutes, and each other Credit Document to which any Credit Party

     any agreement or other instrument pursuant to which any Consolidated Party
     or any ERISA Affiliate has agreed or is required to indemnify any person
     against any such liability.

     3(1) of ERISA) to which Sections 601-609 of ERISA and Section 4980B of the

     with the regulations issued under Section 401(c)(1)(A) of ERISA, or the
     issuance of any other prohibited transaction exemption or similar relief,
     to the effect that assets in an insurance company's general asset account
     do not constitute assets of an "employee benefit plan" within the meaning
     of Section 3(3) of ERISA of a "plan" within the meaning of Section
     4975(e)(1) of the Code.

Liens (other than those arising under or contemplated in connection with the
Credit Documents). Other than as set forth in Schedule 6.13, no Consolidated

     the purpose of purchasing or carrying or trading in any securities. If
     requested by any Lender or the Agent, the Borrower will furnish to the
     Agent and each Lender a statement to the foregoing effect in conformity

     Consolidated Party is a director, executive officer or principal
     shareholder of any Lender. For the purposes hereof the terms "director",
     "executive officer" and "principal shareholder" (when used with reference
     to any Lender) have the respective meanings assigned thereto in Regulation
     O issued by the Board of Governors of the Federal Reserve System.

          (d) Each Consolidated Party has obtained and holds in full force and
     effect, all franchises, licenses, permits, certificates, authorizations,
     qualifications, accreditations, easements, rights of way and other rights,

          (k) Year 2000 Compliance. Promptly upon the discovery or determination
     that any computer application that is material to its or any of its
     Subsidiaries' business and operations will not be "Year 2000 Compliant"
     (that is, be able to properly perform date-sensitive functions for all
     dates before and after January 1, 2000), except to the extent that such
     failure could not reasonably be expected to have a Material Adverse Effect.

          (l) Other Information. With reasonable promptness upon any such
     request, such other information regarding the business, properties or
     financial condition of any Consolidated Party as the Agent or the Required
     Lenders may reasonably request.

     7.2  Preservation of Existence and Franchises.

     Except as a result of or in connection with a dissolution, merger or
disposition of a Subsidiary permitted under Section 8.4 or Section 8.5, each
Credit Party will, and will cause each of its Subsidiaries to, do all things
necessary to preserve and keep in full force and effect its existence, rights,
franchises and authority if the failure to do so could reasonably be expected to
have a Material Adverse Effect.

     7.3  Books and Records.

     Each Credit Party will, and will cause each of its Subsidiaries to, keep
complete and accurate books and records of its transactions in accordance with
good accounting practices on the basis of GAAP (including the establishment and
maintenance of appropriate reserves).

     7.4  Compliance with Law.

     Each Credit Party will, and will cause each of its Subsidiaries to, comply
with all laws, rules, regulations and orders, and all applicable restrictions
imposed by all Governmental Authorities, applicable to it and its Property if
noncompliance with any such law, rule, regulation, order or restriction could
reasonably be expected to have a Material Adverse Effect.

     7.5  Payment of Taxes and Other Indebtedness.

     Each Credit Party will, and will cause each of its Subsidiaries to, pay and
discharge (a) all taxes, assessments and governmental charges or levies imposed
upon it, or upon its income or profits, or upon any of its properties, before
they shall become delinquent, (b) all lawful claims (including claims for labor,
materials and supplies) which, if unpaid, might give rise to a Lien upon any of
its properties, and (c) except as prohibited hereunder, all of its other
Indebtedness as it shall become due; provided, however, that no Consolidated
Party shall be required to pay any such tax, assessment, charge, levy, claim or
Indebtedness which is being contested in good faith by appropriate proceedings
and as to which adequate reserves therefor have been established in accordance
with GAAP, unless the failure to make any such payment (i) could give rise to an
immediate right to foreclose on a Lien securing such amounts or (ii) could
reasonably be expected to have a Material Adverse Effect.

     7.6  Insurance.

          (a) Each Credit Party will, and will cause each of its Subsidiaries
     to, at all times maintain in full force and effect insurance (including
     worker's compensation insurance, liability insurance, casualty insurance
     and business interruption insurance) in such amounts, covering such risks
     and liabilities and with such deductibles or self-insurance retentions as
     are in accordance with normal industry practice (or as otherwise required
     by the Collateral Documents). The Agent shall be named as loss payee or
     mortgagee, as its interest may appear, and/or additional insured with
     respect to any such insurance providing coverage in respect of any
     Collateral, and each provider of any such insurance shall agree, by
     endorsement upon the policy or policies issued by it or by independent
     instruments furnished to the Agent, that it will use good faith efforts to
     give the Agent thirty (30) days prior written notice before any such policy
     or policies shall be altered or canceled, and that no act or default of any
     Consolidated Party or any other Person shall affect the rights of the Agent
     or the Lenders under such policy or policies. The present insurance
     coverage of the 


                                       56


     Consolidated Parties is outlined as to carrier, policy number, expiration
     date, type and amount on Schedule 7.6.

          (b) In case of any material loss, damage to or destruction of the
     Collateral of any Credit Party or any part thereof, such Credit Party shall
     promptly give written notice thereof to the Agent generally describing the
     nature and extent of such damage or destruction. In case of any loss,
     damage to or destruction of the Collateral of any Credit Party or any part
     thereof, such Credit Party, whether or not the insurance proceeds, if any,
     received on account of such damage or destruction shall be sufficient for
     that purpose, at such Credit Party's cost and expense, will promptly repair
     or replace the Collateral of such Credit Party so lost, damaged or
     destroyed; provided, however, that such Credit Party need not repair or
     replace the Collateral of such Credit Party so lost, damaged or destroyed
     to the extent the failure to make such repair or replacement (i) is
     desirable to the proper conduct of the business of such Credit Party in the
     ordinary course and otherwise in the best interest of such Credit Party;
     and (ii) would not materially impair the rights and benefits of the Agent
     or the Lenders under the Collateral Documents, any other Credit Document or
     any Hedging Agreement. In the event a Credit Party shall receive any
     proceeds of such insurance in a net amount in excess of $500,000, such
     Credit Party will immediately pay over such proceeds to the Agent, for
     payment on the Credit Party Obligations; provided, however, that the Agent
     agrees to release such insurance proceeds to such Credit Party for
     replacement or restoration of the portion of the Collateral of such Credit
     Party lost, damaged or destroyed if, but only if, (A) no Default or Event
     of Default shall have occurred and be continuing at the time of release,
     (B) written application for such release is received by the Agent from such
     Credit Party within 30 days of receipt of such proceeds and (C) the Agent
     has received evidence reasonably satisfactory to it that the Collateral
     lost, damaged or destroyed has been or will be replaced or restored to its
     condition immediately prior to the loss, destruction or other event giving
     rise to the payment of such insurance proceeds.

     7.7  Maintenance of Property.

     Each Credit Party will, and will cause each of its Subsidiaries to,
maintain and preserve its properties and equipment material to the conduct of
its business in good repair, working order and condition, normal wear and tear
and casualty and condemnation excepted, and will make, or cause to be made, in
such properties and equipment from time to time all repairs, renewals,
replacements, extensions, additions, betterments and improvements thereto as may
be needed or proper, to the extent and in the manner customary for companies in
similar businesses.

     7.8  Performance of Obligations.

     Each Credit Party will, and will cause each of its Subsidiaries to, perform
in all material respects all of its obligations under the terms of all material
agreements, indentures, mortgages, security agreements or other debt instruments
to which it is a party or by which it is bound.

     7.9  Use of Proceeds.

     The Borrower will use the proceeds of the Loans and will use the Letters of
Credit solely for the purposes set forth in Section 6.15.

     7.10 Audits/Inspections.

     Upon reasonable notice and during normal business hours, each Credit Party
will, and will cause each of its Subsidiaries to, permit representatives
appointed by the Agent, including, without limitation, independent accountants,
agents, attorneys, and appraisers to visit and inspect its property, including
its books and records, its accounts receivable and inventory, its facilities and
its other business assets, and to make photocopies or photographs thereof and to
write down and record any information such representative obtains and shall
permit the Agent or its representatives to investigate and verify the accuracy
of information provided to the Lenders and to discuss all such matters with the
officers, employees and representatives of such Person. The Credit Parties agree
that the Agent, and its representatives, may conduct an annual audit of the
Collateral, at the expense of the Borrower.

     Credit Parties shall have delivered to the Agent:

          (subject to Permitted Liens) on such leasehold interest in favor of

          Title Insurance Company (the "Mortgage Policies"), in amounts

          priority mortgage lien on the applicable Primary Real Property, free
          and clear of all defects and encumbrances except Permitted Liens,
          which Mortgage Policies shall be in form and substance reasonably
          satisfactory to the Agent and shall provide for affirmative insurance
          and such reinsurance as the Agent may reasonably request, all of the

          each of the Real Properties, the permitted uses of each such Real
          Properties under such zoning designation and zoning requirements as to

     obligations of any and every kind owing by the Borrower to the Agent and/or
     any of the Lenders hereunder to be due whereupon the same shall be
     immediately due and payable without presentment, demand, protest or other
     notice of any kind, all of which are hereby waived by the Borrower.

          (c) Cash Collateral. Direct the Borrower to pay (and the Borrower
     agrees that upon receipt of such notice, or upon the occurrence of an Event
     of Default under Section 9.1(e), it will immediately pay) to the Agent
     additional cash, to be held by the Agent, for the benefit of the Lenders,
     in a cash collateral account as additional security for the LOC Obligations
     in respect of subsequent drawings under all then outstanding Letters of
     Credit in an amount equal to the maximum aggregate amount which may be
     drawn under all Letters of Credits then outstanding.

          (d) Enforcement of Rights. Enforce any and all rights and interests
     created and existing under the Credit Documents including, without
     limitation, all rights and remedies existing under the Collateral
     Documents, all rights and remedies against a Guarantor and all rights of
     set-off.

     Notwithstanding the foregoing, if an Event of Default specified in Section
9.1(e) shall occur, then the Commitments shall automatically terminate and all
Loans, all reimbursement obligations arising from drawings under Letters of
Credit, all accrued interest in respect thereof, all accrued and unpaid Fees and
other indebtedness or obligations owing to the Agent and/or any of the Lenders
hereunder automatically shall immediately become due and payable without the
giving of any notice or other action by the Agent or the Lenders.


                                   SECTION 10

                                AGENCY PROVISIONS

     10.1 Appointment, Powers and Immunities.

     Each Lender hereby irrevocably appoints and authorizes the Agent to act as
its agent under this Credit Agreement and the other Credit Documents with such
powers and discretion as are specifically delegated to the Agent by the terms of
this Credit Agreement and the other Credit Documents, together with such other
powers as are reasonably incidental thereto. The Agent (which term as used in
this sentence and in Section 10.5 and the first sentence of Section 10.6 hereof
shall include its Affiliates and its own and its Affiliates' officers,
directors, employees, and agents): (a) shall not have any duties or
responsibilities except those expressly set forth in this Credit Agreement and
shall not be a trustee or fiduciary for any Lender; (b) shall not be responsible
to the Lenders for any recital, statement, representation, or warranty (whether
written or oral) made in or in connection with any Credit Document or any
certificate or other document referred to or provided for in, or received by any
of them under, any Credit Document, or for the value, validity, effectiveness,
genuineness, enforceability, or sufficiency of 


                                       68



any Credit Document, or any other document referred to or provided for therein
or for any failure by any Credit Party or any other Person to perform any of its
obligations thereunder; (c) shall not be responsible for or have any duty to
ascertain, inquire into, or verify the performance or observance of any
covenants or agreements by any Credit Party or the satisfaction of any condition
or to inspect the property (including the books and records) of any Credit Party
or any of its Subsidiaries or Affiliates; (d) shall not be required to initiate
or conduct any litigation or collection proceedings under any Credit Document;
and (e) shall not be responsible for any action taken or omitted to be taken by
it under or in connection with any Credit Document, except for its own gross
negligence or willful misconduct. The Agent may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it with reasonable care.

     10.2 Reliance by Agent.

     The Agent shall be entitled to rely upon any certification, notice,
instrument, writing, or other communication (including, without limitation, any
thereof by telephone or telecopy) believed by it to be genuine and correct and
to have been signed, sent or made by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel (including counsel for
any Credit Party), independent accountants, and other experts selected by the
Agent. The Agent may deem and treat the payee of any Note as the holder thereof
for all purposes hereof unless and until the Agent receives and accepts an
Assignment and Acceptance executed in accordance with Section 11.3(b) hereof. As
to any matters not expressly provided for by this Credit Agreement, the Agent
shall not be required to exercise any discretion or take any action, but shall
be required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Required Lenders,
and such instructions shall be binding on all of the Lenders; provided, however,
that the Agent shall not be required to take any action that exposes the Agent
to personal liability or that is contrary to any Credit Document or applicable
law or unless 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 any such action.

     10.3 Defaults.

     The Agent shall not be deemed to have knowledge or notice of the occurrence
of a Default or Event of Default unless the Agent has received written notice
from a Lender or the Borrower specifying 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 of the occurrence of a Default or Event of Default, the
Agent shall give prompt notice thereof to the Lenders. The Agent shall (subject
to Section 10.2 hereof) take such action with respect to such Default or Event
of Default as shall reasonably be 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 interest of the Lenders.

     10.4 Rights as a Lender.

     With respect to its Commitment and the Loans made by it, NationsBank (and
any successor acting as Agent) in its capacity as a Lender hereunder shall have
the same rights and powers hereunder as any other Lender and may exercise the
same as though it were not acting as the Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include the Agent in
its individual capacity. NationsBank (and any successor acting as Agent) and its
Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in, provide services to, and
generally engage in any kind of lending, trust, or other business with any
Credit Party or any of its Subsidiaries or Affiliates as if it were not acting
as Agent, and NationsBank (and any successor acting as Agent) and its Affiliates
may accept fees and other consideration from any Credit Party or any of its
Subsidiaries or Affiliates for services in connection with this Credit Agreement
or otherwise without having to account for the same to the Lenders.

     10.5 Indemnification.

     The Lenders agree to indemnify the Agent (to the extent not reimbursed
under Section 11.5 hereof, but without limiting the obligations of the Borrower
under such Section) ratably in accordance with their respective Commitments, for
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses (including attorneys' fees), or disbursements
of any kind and nature whatsoever that may be imposed on, 


                                       69


incurred by or asserted against the Agent (including by any Lender) in any way
relating to or arising out of any Credit Document or the transactions
contemplated thereby or any action taken or omitted by the Agent under any
Credit Document (including any of the foregoing arising from the negligence of
the Agent; provided that no Lender shall be liable for any of the foregoing to
the extent they arise from the gross negligence or willful misconduct of the
Person to be indemnified. Without limitation of the foregoing, each Lender
agrees to reimburse the Agent promptly upon demand for its ratable share of any
costs or expenses payable by the Borrower under Section 11.5, to the extent that
the Agent is not promptly reimbursed for such costs and expenses by the
Borrower. The agreements in this Section 10.5 shall survive the repayment of the
Loans, LOC Obligations and other obligations under the Credit Documents and the
termination of the Commitments hereunder.

     10.6 Non-Reliance on Agent and Other Lenders.

     Each Lender agrees that it has, independently and without reliance on the
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Credit Parties and their
Subsidiaries and decision to enter into this Credit Agreement and that it will,
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own analysis and decisions in taking or not taking action
under the Credit Documents. Except for notices, reports, and other documents and
information expressly required to be furnished to the Lenders by the Agent
hereunder, the Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition, or business of any Credit Party or any of its Subsidiaries or
Affiliates that may come into the possession of the Agent or any of its
Affiliates.

     10.7 Successor Agent.

     The Agent may resign at any time by giving notice thereof to the Lenders
and the Borrower. Upon any such resignation, the Borrower, with the consent of
the Required Lenders (such consent not to be unreasonably withheld) shall have
the right to appoint a successor Agent from among the Lenders. If no successor
Agent shall have been so appointed by the Required Lenders and shall have
accepted such appointment within thirty (30) days after the retiring Agent's
giving of notice of resignation, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent which shall be a commercial bank organized
under the laws of the United States of America having combined capital and
surplus of at least $100,000,000. Upon the acceptance of any appointment as
Agent hereunder by a successor, such successor shall thereupon succeed to and
become vested with all the rights, powers, discretion, 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 10 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 Agent.

     11.2 Right of Set-Off; Adjustments.

     Upon the occurrence and during the continuance of any Event of Default,
each Lender (and each of its Affiliates) is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender (or any
of its Affiliates) to or for the credit or the account of any Credit Party
against any and all of the obligations of such Person now or hereafter existing
under this Credit Agreement, under the Notes, under any other Credit Document or
otherwise, irrespective of whether such Lender shall have made any demand under
hereunder or thereunder and although such obligations may be unmatured. Each
Lender agrees promptly to notify any affected Credit Party after any such
set-off and application made by such Lender; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 11.2 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) that such Lender may have.



                                       71


     11.3 Benefit of Agreement.

          (a) This Credit Agreement shall be binding upon and inure to the
     benefit of and be enforceable by the respective successors and assigns of
     the parties hereto; provided that none of the Credit Parties may assign or
     transfer any of its interests and obligations without prior written consent
     of the Lenders; provided further that the rights of each Lender to
     transfer, assign or grant participations in its rights and/or obligations
     hereunder shall be limited as set forth in this Section 11.3.

          (b) Each Lender may assign to one or more Eligible Assignees all or a
     portion of its rights and obligations under this Credit Agreement
     (including, without limitation, all or a portion of its Loans, its Notes,
     and its Commitment); provided, however, that

               (i) each such assignment shall be to an Eligible Assignee;

               (ii) except in the case of an assignment to another Lender or an
          Approved Fund (as referred to in the definition of "Eligible
          Assignee") or an assignment of all of a Lender's rights and
          obligations under this Credit Agreement, any such partial assignment
          shall be in an amount at least equal to $5,000,000 (or, if less, the
          remaining amount of the Commitment being assigned by such Lender) or
          an integral multiple of $1,000,000 in excess thereof;

               (iii) each such assignment by a Lender shall be of a constant,
          and not varying, percentage of all of its rights and obligations under
          this Credit Agreement and the Notes; and

               (iv) the parties to such assignment shall execute and deliver to
          the Agent for its acceptance an Assignment and Acceptance in the form
          of Exhibit 11.3(b) hereto, together with any Note subject to such
          assignment and a processing fee of $3,500; provided that no such fee
          shall be payable in the case of an assignment by a Lender to (A) an
          Affiliate of such Lender or (B) an Approved Fund (as referred to in
          the definition of "Eligible Assignee") which is an Affiliate of such
          Lender.

     Upon execution, delivery, and acceptance of such Assignment and Acceptance,
     the assignee thereunder shall be a party hereto and, to the extent of such
     assignment, have the obligations, rights, and benefits of a Lender
     hereunder and the assigning Lender shall, to the extent of such assignment,
     relinquish its rights and be released from its obligations under this
     Credit Agreement. Upon the consummation of any assignment pursuant to this
     Section 11.3(b), the assignor, the Agent and the Borrower shall make
     appropriate arrangements so that, if required, new Notes are issued to the
     assignor and the assignee. If the assignee is not incorporated under the
     laws of the United States of America or a state thereof, it shall deliver
     to the Borrower and the Agent certification as to exemption from deduction
     or withholding of Taxes in accordance with Section 3.11.

          (c) The Agent shall maintain at its address referred to in Section
     11.1 a copy of each Assignment and Acceptance delivered to and accepted by
     it and a register for the recordation of the names and addresses of the
     Lenders and the Commitment of, and principal amount of the Loans owing to,
     each Lender from time to time (the "Register"). The entries in the Register
     shall be conclusive and binding for all purposes, absent 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 Credit Agreement. The Register shall be available for inspection by
     the Borrower or any Lender at any reasonable time and from time to time
     upon reasonable prior notice.

          (d) Upon its receipt of an Assignment and Acceptance executed by the
     parties thereto, together with any Note subject to such assignment and
     payment of the processing fee, the Agent shall, if such Assignment and
     Acceptance has been completed and is in substantially the form of Exhibit
     11.3(b) hereto, (i) accept such Assignment and Acceptance, (ii) record the
     information contained therein in the Register and (iii) give prompt notice
     thereof to the parties thereto.



                                       72



          (e) Each Lender may sell participations to one or more Persons in all
     or a portion of its rights, obligations or rights and obligations under
     this Credit Agreement (including all or a portion of its Commitment and its
     Loans); provided, however, that (i) such Lender's obligations under this
     Credit Agreement shall remain unchanged, (ii) such Lender shall remain
     solely responsible to the other parties hereto for the performance of such
     obligations, (iii) the participant shall be entitled to the benefit of the
     yield protection provisions contained in Sections 3.7 through 3.12,
     inclusive, and the right of set-off contained in Section 11.2, and (iv) the
     Borrower shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Credit
     Agreement, and such Lender shall retain the sole right to enforce the
     obligations of the Borrower relating to its Loans and its Notes and to
     approve any amendment, modification, or waiver of any provision of this
     Credit Agreement (other than amendments, modifications, or waivers
     decreasing the amount of principal of or the rate at which interest is
     payable on such Loans or Notes, extending any scheduled principal payment
     date or date fixed for the payment of interest on such Loans or Notes, or
     extending its Commitment).

          (f) Notwithstanding any other provision set forth in this Credit
     Agreement, any Lender may at any time assign and pledge all or any portion
     of its Loans and its Notes to any Federal Reserve Bank as collateral
     security pursuant to Regulation A and any Operating Circular issued by such
     Federal Reserve Bank. No such assignment shall release the assigning Lender
     from its obligations hereunder.

          (g) Any Lender may furnish any information concerning the Borrower or
     any of its Subsidiaries in the possession of such Lender from time to time
     to assignees and participants (including prospective assignees and
     participants).

     11.4 No Waiver; Remedies Cumulative.

     No failure or delay on the part of the Agent or any Lender in exercising
any right, power or privilege hereunder or under any other Credit Document and
no course of dealing between the Agent or any Lender and any of the Credit
Parties shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights and remedies
provided herein are cumulative and not exclusive of any rights or remedies which
the Agent or any Lender would otherwise have. No notice to or demand on any
Credit Party in any case shall entitle the Borrower or any other Credit Party to
any other or further notice or demand in similar or other circumstances or
constitute a waiver of the rights of the Agent or the Lenders to any other or
further action in any circumstances without notice or demand.

     11.5 Expenses; Indemnification.

     (a) The Borrower agrees to pay on demand all costs and expenses of the
Agent in connection with the syndication, preparation, execution, delivery,
administration, modification, and amendment of this Credit Agreement, the other
Credit Documents, and the other documents to be delivered hereunder, including,
without limitation, the reasonable fees and expenses of counsel for the Agent
(including the cost of internal counsel) with respect thereto and with respect
to advising the Agent as to its rights and responsibilities under the Credit
Documents. The Borrower further agrees to pay on demand all costs and expenses
of the Agent and the Lenders, if any (including, without limitation, reasonable
attorneys' fees and expenses and the cost of internal counsel), in connection
with the enforcement (whether through negotiations, legal proceedings, or
otherwise) of the Credit Documents and the other documents to be delivered
hereunder.

     (b) The Borrower agrees to indemnify and hold harmless the Agent and each
Lender and each of their Affiliates and their respective officers, directors,
employees, agents, and advisors (each, an "Indemnified Party") from and against
any and all claims, damages, losses, liabilities, costs, and expenses
(including, without limitation, reasonable attorneys' fees) that may be incurred
by or asserted or awarded against any Indemnified Party, in each case arising
out of or in connection with or by reason of (including, without limitation, in
connection with any investigation, litigation, or proceeding or preparation of
defense in connection therewith) the Credit Documents, any of the transactions
contemplated herein or the actual or proposed use of the proceeds of the Loans
(including any of the foregoing arising from the negligence of the Indemnified
Party), except to the extent such claim, damage, loss, liability, cost, or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have 


                                       73



resulted from such Indemnified Party's gross negligence or willful misconduct.
In the case of an investigation, litigation or other proceeding to which the
indemnity in this Section 11.5 applies, such indemnity shall be effective
whether or not such investigation, litigation or proceeding is brought by the
Borrower, its directors, shareholders or creditors or an Indemnified Party or
any other Person or any Indemnified Party is otherwise a party thereto and
whether or not the transactions contemplated hereby are consummated. The
Borrower agrees not to assert any claim against the Agent, any Lender, any of
their Affiliates, or any of their respective directors, officers, employees,
attorneys, agents, and advisers, on any theory of liability, for special,
indirect, consequential, or punitive damages arising out of or otherwise
relating to the Credit Documents, any of the transactions contemplated herein or
the actual or proposed use of the proceeds of the Loans.

     (c) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 11.5 shall survive the repayment of the Loans, LOC Obligations and
other obligations under the Credit Documents and the termination of the
Commitments hereunder.

     11.6 Amendments, Waivers and Consents.

     Neither this Credit Agreement nor any other Credit Document nor any of the
terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Borrower, provided, however, that:

          (a) without the consent of each Lender affected thereby, neither this
     Credit Agreement nor any other Credit Document may be amended to


               (i) extend the final maturity of any Loan or the time of payment
          of any reimbursement obligation, or any portion thereof, arising from
          drawings under Letters of Credit, or extend or waive any Principal
          Amortization Payment of any Loan, or any portion thereof,

               (ii) reduce the rate or extend the time of payment of interest
          (other than as a result of waiving the applicability of any
          post-default increase in interest rates) thereon or Fees hereunder,

               (iii) reduce or waive the principal amount of any Loan or of any
          reimbursement obligation, or any portion thereof, arising from
          drawings under Letters of Credit,

               (v) increase the Commitment of a Lender over the amount thereof
          in effect (it being understood and agreed that a waiver of any Default
          or Event of Default or mandatory reduction in the Commitments shall
          not constitute a change in the terms of any Commitment of any Lender),

               (v) except as the result of or in connection with an Asset
          Disposition permitted by Section 8.5, release all or substantially all
          of the Collateral,

               (vi) except as the result of or in connection with a dissolution,
          merger or disposition of a Subsidiary permitted under Section 8.4,
          release the Borrower or substantially all of the other Credit Parties
          from its or their obligations under the Credit Documents,

     forum.

     Credit Agreement shall be binding upon and inure to the benefit of the
     Borrowers, the Guarantors, the Agent and each Lender and their respective
     successors and assigns.

          (d) At such time as this Amendment shall have become effective

     purposes of acknowledging and consenting to the termination of their
     Commitments under the Existing Credit Facility and waiver of any right to
     receive compensation under Section 3.12 of the Existing Credit Agreement.

     11.14 Source of Funds.

     Each of the Lenders hereby represents and warrants to the Borrower that at
least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

          (a) no part of such funds constitutes assets allocated to any separate
     account maintained by such Lender in which any employee benefit plan (or
     its related trust) has any interest;

          (b) to the extent that any part of such funds constitutes assets
     allocated to any separate account maintained by such Lender, such Lender
     has disclosed to the Borrower the name of each employee benefit plan whose
     assets in such account exceed 10% of the total assets of such account as of
     the date of such purchase (and, for purposes of this subsection (b), all
     employee benefit plans maintained by the same employer or employee
     organization are deemed to be a single plan);

          (c) to the extent that any part of such funds constitutes assets of an
     insurance company's general account, such insurance company has complied
     with all of the requirements of the regulations issued under Section
     401(c)(1)(A) of ERISA; or

          (d) such funds constitute assets of one or more specific benefit plans
     which such Lender has identified in writing to the Borrower.

As used in this Section 11.15, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

     11.15 Conflict.

     To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Credit Agreement shall control.

     11.16 Confidentiality.

     The Agent and each Lender (each, a "Lending Party") agrees to keep
confidential any information furnished or made available to it by the Borrower
pursuant to this Credit Agreement that is marked confidential; provided that
nothing herein shall prevent any Lending Party from disclosing such information
(a) to any other Lending Party or any Affiliate of any Lending Party, or any
officer, director, employee, agent, or advisor of any Lending Party or Affiliate
of any Lending Party, (b) to any other Person if reasonably incidental to the
administration of the credit facility provided herein, (c) as required by any
law, rule, or regulation, (d) upon the order of any court or administrative
agency, (e) upon the request or demand of any regulatory agency or authority,
(f) that is or becomes available to the public or that is or becomes available
to any Lending Party other than as a result of a disclosure by any Lending Party
prohibited by this Credit Agreement, (g) in connection with any litigation to
which such Lending Party or any of its Affiliates may be a party, (h) to the
extent necessary in connection with the exercise of any remedy under this Credit
Agreement or any other Credit Document, and (i) subject to provisions
substantially similar to those contained in this Section 11.16, to any actual or
proposed participant or assignee; provided, however, that in the event that any
Lending Party is requested to disclose any confidential information pursuant to
clause (c), (d), (e) or (g) above, then such Lending Party shall, to the extent
lawfully permitted, use reasonable best efforts to promptly notify the Borrower.

                            FORM OF PLEDGE AGREEMENT

         THIS PLEDGE AGREEMENT (this "Pledge Agreement") is entered into as of
October 14, 1997 among INSIGHT HEALTH SERVICES CORP., a Delaware corporation
(the "Borrower"), certain Subsidiaries of the Borrower (individually a
"Guarantor", and collectively the "Guarantors"; together with the Borrower,
individually a "Pledgor", and collectively the "Pledgors") and NATIONSBANK,
N.A., in its capacity as agent (in such capacity, the "Agent") for the lenders
from time to time party to the Credit Agreement described below (the "Lenders").

                                    RECITALS

         WHEREAS, pursuant to that certain Credit Agreement dated as of the date
hereof (as amended, modified, extended, renewed or replaced from time to time,
the "Credit Agreement") among the Borrower, the Guarantors, the Lenders and the
Agent, the Lenders have agreed to make Loans and issue Letters of Credit upon
the terms and subject to the conditions set forth therein; and

         WHEREAS, it is a condition precedent to the effectiveness of the Credit
Agreement and the obligations of the Lenders to make their respective Loans and
to issue Letters of Credit under the Credit Agreement that the Pledgors shall
have executed and delivered this Pledge Agreement to the Agent for the ratable
benefit of the Lenders.

         NOW, THEREFORE, in consideration of these premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

         1. Definitions. Unless otherwise defined herein, capitalized terms used
herein shall have the meanings ascribed to such terms in the Credit Agreement.
For purposes of this Pledge Agreement, the term "Lender" shall include any
Affiliate of any Lender which has entered into a Hedging Agreement with the
Borrower.

         2. Pledge and Grant of Security Interest. To secure the prompt payment
and performance in full when due, whether by lapse of time or otherwise, of the
Pledgor Obligations (as defined in Section 3 hereof), each Pledgor hereby
pledges and assigns to the Agent, for the benefit of the Lenders, and grants to
the Agent, for the benefit of the Lenders, a continuing security interest in any
and all right, title and interest of such Pledgor in and to the following,
whether now owned or existing or owned, acquired, or arising hereafter
(collectively, the "Pledged Collateral"):

                           (a) Pledged Shares. 100% (or, if less, the full
         amount owned by such Pledgor) of the issued and outstanding shares of
         capital stock owned by such Pledgor of each Subsidiary set forth on
         Schedule 2(a) attached hereto, in each case together with the
         certificates (or other agreements or instruments), if any, representing
         such shares, and all options and other rights, contractual or
         otherwise, with respect thereto (collectively, together with the shares
         of capital stock described in Section 2(b) and 2(c) below, the "Pledged
         Shares"), including, but not limited to, the following:

                           (y) all shares or securities representing a dividend
                  on any of the Pledged Shares, or representing a distribution
                  or return of capital upon or in respect of the Pledged Shares,
                  or resulting from a stock split, revision, reclassification or
                  other exchange therefor, and any subscriptions, warrants,
                  rights or options issued to the holder of, or otherwise in
                  respect of, the Pledged Shares; and

                           (z) without affecting the obligations of the Pledgors
                  under any provision prohibiting such action hereunder or under
                  the Credit Agreement, in the event of any consolidation or
                  merger involving the issuer of any Pledged Shares and in which
                  such issuer is not the surviving corporation, all shares of
                  each class of the capital stock of the successor corporation
                  formed by or resulting from such consolidation or merger.



                                       -1-




                  (b) Additional Shares. 100% (or, if less, the full amount
         owned by such Pledgor) of the issued and outstanding shares of capital
         stock owned by such Pledgor of any Person which is not a Joint Venture
         and hereafter becomes a Subsidiary, including, without limitation, the
         certificates representing such shares.

                  (c) Other Equity Interests. Any and all other Capital Stock in
         each Pledgor in any Subsidiary which is not a Joint Venture.

                  (d) Proceeds. All proceeds and products of the foregoing,
         however and whenever acquired and in whatever form.

         Without limiting the generality of the foregoing, it is hereby
specifically understood and agreed that a Pledgor may from time to time
hereafter deliver additional shares of stock to the Agent as collateral security
for the Pledgor Obligations. Upon delivery to the Agent, such additional shares
of stock shall be deemed to be part of the Pledged Collateral of such Pledgor
and shall be subject to the terms of this Pledge Agreement whether or not
Schedule 2(a) is amended to refer to such additional shares.

         3. Security for Pledgor Obligations. The security interest created
hereby in the Pledged Collateral of each Pledgor constitutes continuing
collateral security for all of the following, whether now existing or hereafter
incurred (the "Pledgor Obligations"):

                  (a) In the case of the Borrower, the prompt performance and
         observance by the Borrower of all obligations of the Borrower under the
         Credit Agreement, the Notes, this Pledge Agreement and the other Credit
         Documents to which the Borrower is a party;

                  (b) In the case of the Guarantors, the prompt performance and
         observance by such Guarantor of all obligations of such Guarantor under
         the Credit Agreement, this Pledge Agreement and the other Credit
         Documents to which such Guarantor is a party, including, without
         limitation, its guaranty obligations arising under Section 4 of the
         Credit Agreement; and

                  (c) All other indebtedness, liabilities and obligations of any
         kind or nature, now existing or hereafter arising, owing from any
         Pledgor to any Lender or the Agent, howsoever evidenced, created,
         incurred or acquired, whether primary, secondary, direct, contingent,
         or joint and several, including, without limitation, all liabilities
         arising under Hedging Agreements and all obligations and liabilities
         incurred in connection with collecting and enforcing the Pledgor
         Obligations.

         4. Delivery of the Pledged Collateral. Each Pledgor hereby agrees that:

                  (a) Each Pledgor shall deliver to the Agent (i) simultaneously
         with or prior to the execution and delivery of this Pledge Agreement,
         all certificates representing the Pledged Shares of such Pledgor and
         (ii) promptly upon the receipt thereof by or on behalf of a Pledgor,
         all other certificates and instruments constituting Pledged Collateral
         of a Pledgor. Prior to delivery to the Agent, all such certificates and
         instruments constituting Pledged Collateral of a Pledgor shall be held
         in trust by such Pledgor for the benefit of the Agent pursuant hereto.
         All such certificates shall be delivered in suitable form for transfer
         by delivery or shall be accompanied by duly executed instruments of
         transfer or assignment in blank, substantially in the form provided in
         Exhibit 4(a) attached hereto.

                  (b) Additional Securities. If such Pledgor shall receive by
         virtue of its being or having been the owner of any Pledged Collateral,
         any (i) stock certificate, including without limitation, any
         certificate representing a stock dividend or distribution in connection
         with any increase or reduction of capital, reclassification, merger,
         consolidation, sale of assets, combination of shares, stock splits,
         spin-off or split-off, promissory notes or other instrument; (ii)
         option or right, whether as an addition to, substitution for, or an
         exchange for, any Pledged Collateral or otherwise; (iii) dividends
         payable in securities; or 



                                      -2-



         (iv) distributions of securities in connection with a partial or total
         liquidation, dissolution or reduction of capital, capital surplus or
         paid-in surplus, then such Pledgor shall receive such stock
         certificate, instrument, option, right or distribution in trust for
         the benefit of the Agent, shall segregate it from such Pledgor's other
         property and shall deliver it forthwith to the Agent in the exact form
         received together with any necessary endorsement and/or appropriate
         stock power duly executed in blank, substantially in the form provided
         in Exhibit 4(a), to be held by the Agent as Pledged Collateral and as
         further collateral security for the Pledgor Obligations.

                  (c) Financing Statements. Each Pledgor shall execute and
         deliver to the Agent such UCC or other applicable financing statements
         as may be reasonably requested by the Agent in order to perfect and
         protect the security interest created hereby in the Pledged Collateral
         of such Pledgor.

         5. Representations and Warranties. Each Pledgor hereby represents and
warrants to the Agent, for the benefit of the Lenders, that so long as any of
the Pledgor Obligations remain outstanding or any Credit Document or Hedging
Agreement is in effect or any Letter of Credit shall remain outstanding, and
until all of the Commitments shall have been terminated:

                  (a) Authorization of Pledged Shares. The Pledged Shares are
         duly authorized and validly issued, are fully paid and nonassessable
         and are not subject to the preemptive rights of any Person. All other
         shares of stock constituting Pledged Collateral will be duly authorized
         and validly issued, fully paid and nonassessable and not subject to the
         preemptive rights of any Person.

                  (b) Title. Each Pledgor has good and indefeasible title to the
         Pledged Collateral of such Pledgor and will at all times be the legal
         and beneficial owner of such Pledged Collateral free and clear of any
         Lien, other than Permitted Liens. There exists no "adverse claim"
         within the meaning of Section 8-302 of the Uniform Commercial Code as
         in effect in the State of New York (the "UCC") with respect to the
         Pledged Shares of such Pledgor.

                  (c) Exercising of Rights. The exercise by the Agent of its
         rights and remedies hereunder will not violate any law or governmental
         regulation or any material contractual restriction binding on or
         affecting a Pledgor or any of its property.

                  (d) Pledgor's Authority. No authorization, approval or action
         by, and no notice or filing with any Governmental Authority or with the
         issuer of any Pledged Stock is required either (i) for the pledge made
         by a Pledgor or for the granting of the security interest by a Pledgor
         pursuant to this Pledge Agreement or (ii) for the exercise by the Agent
         or the Lenders of their rights and remedies hereunder (except as may be
         required by laws affecting the offering and sale of securities).

                  (e) Security Interest/Priority. This Pledge Agreement creates
         a valid security interest in favor of the Agent for the benefit of the
         Lenders, in the Pledged Collateral. The taking possession by the Agent
         of the certificates representing the Pledged Shares and all other
         certificates and instruments constituting Pledged Collateral will
         perfect and establish the first priority of the Agent's security
         interest in the Pledged Shares and, when properly perfected by filing
         or registration, in all other Pledged Collateral represented by such
         Pledged Shares and instruments securing the Pledgor Obligations. Except
         as set forth in this Section 5(e), no action is necessary to perfect or
         otherwise protect such security interest.

                  (f) No Other Shares. No Pledgor owns any shares of stock other
         than as set forth on Schedule 2(a) attached hereto.

         6. Covenants. Each Pledgor hereby covenants, that so long as any of the
Pledgor Obligations remain outstanding or any Credit Document or Hedging
Agreement is in effect or any Letter of Credit shall remain outstanding, and
until all of the Commitments shall have been terminated, such Pledgor shall:



                                      -3-



                  (a) Books and Records. Mark its books and records (and shall
         cause the issuer of the Pledged Shares of such Pledgor to mark its
         books and records) to reflect the security interest granted to the
         Agent, for the benefit of the Lenders, pursuant to this Pledge
         Agreement.

                  (b) Defense of Title. Warrant and defend title to and
         ownership of the Pledged Collateral of such Pledgor at its own expense
         against the claims and demands of all other parties claiming an
         interest therein, keep the Pledged Collateral free from all Liens,
         except for Permitted Liens, and not sell, exchange, transfer, assign,
         lease or otherwise dispose of Pledged Collateral of such Pledgor or any
         interest therein, except as permitted under the Credit Agreement and
         the other Credit Documents.

                  (c) Further Assurances. Promptly execute and deliver at its
         expense all further instruments and documents and take all further
         action that may be necessary and desirable or that the Agent may
         reasonably request in order to (i) perfect and protect the security
         interest created hereby in the Pledged Collateral of such Pledgor
         (including without limitation any and all action necessary to satisfy
         the Agent that the Agent has obtained a first priority perfected
         security interest in any capital stock); (ii) enable the Agent to
         exercise and enforce its rights and remedies hereunder in respect of
         the Pledged Collateral of such Pledgor; and (iii) otherwise effect the
         purposes of this Pledge Agreement, including, without limitation and if
         requested by the Agent, delivering to the Agent irrevocable proxies in
         respect of the Pledged Collateral of such Pledgor.

                  (d) Amendments. Not make or consent to any amendment or other
         modification or waiver with respect to any of the Pledged Collateral of
         such Pledgor or enter into any agreement or allow to exist any
         restriction with respect to any of the Pledged Collateral of such
         Pledgor other than pursuant hereto or as may be permitted under the
         Credit Agreement.

                  (e) Compliance with Securities Laws. File all reports and
         other information now or hereafter required to be filed by such Pledgor
         with the United States Securities and Exchange Commission and any other
         state, federal or foreign agency in connection with the ownership of
         the Pledged Collateral of such Pledgor.

         7. Advances by Lenders. On failure of any Pledgor to perform any of the
covenants and agreements contained herein, the Agent may, at its sole option and
in its sole discretion, perform the same and in so doing may expend such sums as
the Agent may reasonably deem advisable in the performance thereof, including,
without limitation, the payment of any insurance premiums, the payment of any
taxes, a payment to obtain a release of a Lien or potential Lien, expenditures
made in defending against any adverse claim and all other expenditures which the
Agent or the Lenders may make for the protection of the security hereof or which
may be compelled to make by operation of law. All such sums and amounts so
expended shall be repayable by the Pledgors on a joint and several basis
promptly upon timely notice thereof and demand therefor, shall constitute
additional Pledgor Obligations and shall bear interest from the date said
amounts are expended at the default rate specified in Section 3.1 of the Credit
Agreement for Revolving Loans that are Base Rate Loans. No such performance of
any covenant or agreement by the Agent or the Lenders on behalf of any Pledgor,
and no such advance or expenditure therefor, shall relieve the Pledgors of any
default under the terms of this Pledge Agreement, the other Credit Documents or
any Hedging Agreement. The Lenders may make any payment hereby authorized in
accordance with any bill, statement or estimate procured from the appropriate
public office or holder of the claim to be discharged without inquiry into the
accuracy of such bill, statement or estimate or into the validity of any tax
assessment, sale, forfeiture, tax lien, title or claim except to the extent such
payment is being contested in good faith by a Pledgor in appropriate proceedings
and against which adequate reserves are being maintained in accordance with
GAAP.

         8. Events of Default. The occurrence of an event which under the Credit
Agreement would constitute an Event of Default shall be an Event of Default
hereunder (an "Event of Default").



                                      -4-



         9.       Remedies.

                  (a) General Remedies. Upon the occurrence of an Event of
         Default and during the continuation thereof, the Agent and the Lenders
         shall have, in respect of the Pledged Collateral of any Pledgor, in
         addition to the rights and remedies provided herein, in the Credit
         Documents, in the Hedging Agreements or by law, the rights and remedies
         of a secured party under the UCC or any other applicable law.

                  (b) Sale of Pledged Collateral. Upon the occurrence of an
         Event of Default and during the continuation thereof, without limiting
         the generality of this Section and the Agent may, in its sole
         discretion, sell or otherwise dispose of or realize upon the Pledged
         Collateral, or any part thereof, in one or more parcels, at public or
         private sale, at any exchange or broker's board or elsewhere, at such
         price or prices and on such other terms as the Agent may deem
         commercially reasonable, for cash, credit or for future delivery or
         otherwise in accordance with applicable law. To the extent permitted by
         law, any Lender may in such event, bid for the purchase of such
         securities. Each Pledgor agrees that, to the extent notice of sale
         shall be required by law and has not been waived by such Pledgor, any
         requirement of reasonable notice shall be met if notice, specifying the
         place of any public sale or the time after which any private sale is to
         be made, is personally served on or mailed, postage prepaid, to such
         Pledgor, in accordance with the notice provisions of Section 11.1 of
         the Credit Agreement at least 10 days before the time of such sale. The
         Agent shall not be obligated to make any sale of Pledged Collateral of
         such Pledgor regardless of notice of sale having been given. The Agent
         may adjourn any public or private sale from time to time by
         announcement at the time and place fixed therefor, and such sale may,
         without further notice, be made at the time and place to which it was
         so adjourned.

                  (c) Private Sale. Upon the occurrence of an Event of Default
         and during the continuation thereof, the Pledgors recognize that the
         Agent may deem it impracticable to effect a public sale of all or any
         part of the Pledged Shares or any of the securities constituting
         Pledged Collateral and that the Agent may, therefore, determine to make
         one or more private sales of any such securities to a restricted group
         of purchasers who will be obligated to agree, among other things, to
         acquire such securities for their own account, for investment and not
         with a view to the distribution or resale thereof. Each Pledgor
         acknowledges that any such private sale may be at prices and on terms
         less favorable to the seller than the prices and other terms which
         might have been obtained at a public sale and, notwithstanding the
         foregoing, agrees that such private sale shall be deemed to have been
         made in a commercially reasonable manner and that the Agent shall have
         no obligation to delay sale of any such securities for the period of
         time necessary to permit the issuer of such securities to register such
         securities for public sale under the Securities Act of 1933. Each
         Pledgor further acknowledges and agrees that any offer to sell such
         securities which has been (i) publicly advertised on a bona fide basis
         in a newspaper or other publication of general circulation in the
         financial community of New York, New York (to the extent that such
         offer may be advertised without prior registration under the Securities
         Act of 1933), or (ii) made privately in the manner described above
         shall be deemed to involve a "public sale" under the UCC,
         notwithstanding that such sale may not constitute a "public offering"
         under the Securities Act of 1933, and the Agent may, in such event, bid
         for the purchase of such securities.

                  (d) Retention of Pledged Collateral. In addition to the rights
         and remedies hereunder, upon the occurrence of an Event of Default, the
         Agent may, after providing the notices required by Section 9-505(2) of
         the UCC or otherwise complying with the requirements of applicable law
         of the relevant jurisdiction, retain all or any portion of the Pledged
         Collateral in satisfaction of the Pledgor Obligations. Unless and until
         the Agent shall have provided such notices, however, the Agent shall
         not be deemed to have retained any Pledged Collateral in satisfaction
         of any Pledgor Obligations for any reason.

                  (e) Deficiency. In the event that the proceeds of any sale,
         collection or realization are insufficient to pay all amounts to which
         the Agent or the Lenders are legally entitled, the Pledgors shall be
         jointly and severally liable for the deficiency, together with interest
         thereon at the default rate specified in Section 3.1 of the Credit
         Agreement for Revolving Loans that are Base Rate Loans, together with
         the costs 



                                      -5-



         of collection and the reasonable fees of any attorneys employed by the
         Agent to collect such deficiency. Any surplus remaining after the full
         payment and satisfaction of the Pledgor Obligations shall be returned
         to the Pledgors or to whomsoever a court of competent jurisdiction
         shall determine to be entitled thereto.

         10. Rights of the Agent.

                  (a) Power of Attorney. In addition to other powers of attorney
         contained herein, each Pledgor hereby designates and appoints the
         Agent, on behalf of the Lenders, and each of its designees or agents as
         attorney-in-fact of such Pledgor, irrevocably and with power of
         substitution, with authority to take any or all of the following
         actions upon the occurrence and during the continuance of an Event of
         Default:

                                  (i) to demand, collect, settle, compromise,
                  adjust and give discharges and releases concerning the Pledged
                  Collateral of such Pledgor, all as the Agent may reasonably
                  determine;

                                 (ii) to commence and prosecute any actions at
                  any court for the purposes of collecting any of the Pledged
                  Collateral of such Pledgor and enforcing any other right in
                  respect thereof;

                                (iii) to defend, settle or compromise any action
                  brought and, in connection therewith, give such discharge or
                  release as the Agent may deem reasonably appropriate;

                                 (iv) to pay or discharge taxes, liens, security
                  interests, or other encumbrances levied or placed on or
                  threatened against the Pledged Collateral of such Pledgor;

                                  (v) to direct any parties liable for any
                  payment under any of the Pledged Collateral to make payment of
                  any and all monies due and to become due thereunder directly
                  to the Agent or as the Agent shall direct;

                                 (vi) to receive payment of and receipt for any
                  and all monies, claims, and other amounts due and to become
                  due at any time in respect of or arising out of any Pledged
                  Collateral of such Pledgor;

                                (vii) to sign and endorse any drafts,
                  assignments, proxies, stock powers, verifications, notices and
                  other documents relating to the Pledged Collateral of such
                  Pledgor;

                               (viii) to settle, compromise or adjust any suit,
                  action or proceeding described above and, in connection
                  therewith, to give such discharges or releases as the Agent
                  may deem reasonably appropriate;

                                 (ix) execute and deliver all assignments,
                  conveyances, statements, financing statements, renewal
                  financing statements, pledge agreements, affidavits, notices
                  and other agreements, instruments and documents that the Agent
                  may determine necessary in order to perfect and maintain the
                  security interests and liens granted in this Pledge Agreement
                  and in order to fully consummate all of the transactions
                  contemplated therein;

                                  (x) to exchange any of the Pledged Collateral
                  of such Pledgor or other property upon any merger,
                  consolidation, reorganization, recapitalization or other
                  readjustment of the issuer thereof and, in connection
                  therewith, deposit any of the Pledged Collateral of such
                  Pledgor with any committee, depository, transfer agent,
                  registrar or other designated agency upon such terms as the
                  Agent may determine; and



                                      -6-




                                 (xi) to do and perform all such other acts and
                  things as the Agent may reasonably deem to be necessary,
                  proper or convenient in connection with the Pledged Collateral
                  of such Pledgor.

         This power of attorney is a power coupled with an interest and shall be
         irrevocable (i) for so long as any of the Pledgor Obligations remain
         outstanding, any Credit Document or any Hedging Agreement is in effect
         or any Letter of Credit shall remain outstanding and (ii) until all of
         the Commitments shall have been terminated. The Agent shall be under no
         duty to exercise or withhold the exercise of any of the rights, powers,
         privileges and options expressly or implicitly granted to the Agent in
         this Pledge Agreement, and shall not be liable for any failure to do so
         or any delay in doing so. The Agent shall not be liable for any act or
         omission or for any error of judgment or any mistake of fact or law in
         its individual capacity or its capacity as attorney-in-fact except acts
         or omissions resulting from its gross negligence or willful misconduct.
         This power of attorney is conferred on the Agent solely to protect,
         preserve and realize upon its security interest in Pledged Collateral.

                  (b) Performance by the Agent of Pledgor's Obligations. If any
         Pledgor fails to perform any agreement or obligation contained herein,
         the Agent itself may perform, or cause performance of, such agreement
         or obligation, and the expenses of the Agent incurred in connection
         therewith shall be payable by the Pledgors on a joint and several basis
         pursuant to Section 13 hereof.

                  (c) Assignment by the Agent. The Agent may from time to time
         assign the Pledgor Obligations and any portion thereof and/or the
         Pledged Collateral and any portion thereof, and the assignee shall be
         entitled to all of the rights and remedies of the Agent under this
         Pledge Agreement in relation thereto.

                  (d) The Agent's Duty of Care. Other than the exercise of
         reasonable care to assure the safe custody of the Pledged Collateral
         while being held by the Agent hereunder, the Agent shall have no duty
         or liability to preserve rights pertaining thereto, it being understood
         and agreed that Pledgors shall be responsible for preservation of all
         rights in the Pledged Collateral of such Pledgor, and the Agent shall
         be relieved of all responsibility for Pledged Collateral upon
         surrendering it or tendering the surrender of it to the Pledgors. The
         Agent shall be deemed to have exercised reasonable care in the custody
         and preservation of the Pledged Collateral in its possession if such
         Pledged Collateral is accorded treatment substantially equal to that
         which the Agent accords its own property, which shall be no less than
         the treatment employed by a reasonable and prudent agent in the
         industry, it being understood that the Agent shall not have
         responsibility for (i) ascertaining or taking action with respect to
         calls, conversions, exchanges, maturities, tenders or other matters
         relating to any Pledged Collateral, whether or not the Agent has or is
         deemed to have knowledge of such matters; or (ii) taking any necessary
         steps to preserve rights against any parties with respect to any
         Pledged Collateral.

                  (e)      Voting Rights in Respect of the Pledged Collateral.

                                  (i) So long as no Event of Default shall have
                  occurred and be continuing, to the extent permitted by law,
                  each Pledgor may exercise any and all voting and other
                  consensual rights pertaining to the Pledged Collateral of such
                  Pledgor or any part thereof for any purpose not inconsistent
                  with the terms of this Pledge Agreement or the Credit
                  Agreement; and

                                 (ii) Upon the occurrence and during the
                  continuance of an Event of Default, all rights of a Pledgor to
                  exercise the voting and other consensual rights which it would
                  otherwise be entitled to exercise pursuant to paragraph (i) of
                  this Section shall cease and all such rights shall thereupon
                  become vested in the Agent which shall then have the sole
                  right to exercise such voting and other consensual rights.



                                      -7-



                  (f)      Dividend Rights in Respect of the Pledged Collateral.

                                  (i) So long as no Event of Default shall have
                  occurred and be continuing and subject to Section 4(b) hereof,
                  each Pledgor may receive and retain any and all dividends
                  (other than stock dividends and other dividends constituting
                  Pledged Collateral which are addressed hereinabove) or
                  interest paid in respect of the Pledged Collateral to the
                  extent they are allowed under the Credit Agreement.

                                 (ii) Upon the occurrence and during the
                  continuance of an Event of Default:

                                    (A) all rights of a Pledgor to receive the
                           dividends and interest payments which it would
                           otherwise be authorized to receive and retain
                           pursuant to paragraph (i) of this Section shall cease
                           and all such rights shall thereupon be vested in the
                           Agent which shall then have the sole right to receive
                           and hold as Pledged Collateral such dividends and
                           interest payments; and

                                    (B) all dividends and interest payments
                           which are received by a Pledgor contrary to the
                           provisions of paragraph (A) of this Section shall be
                           received in trust for the benefit of the Agent, shall
                           be segregated from other property or funds of such
                           Pledgor, and shall be forthwith paid over to the
                           Agent as Pledged Collateral in the exact form
                           received, to be held by the Agent as Pledged
                           Collateral and as further collateral security for the
                           Pledgor Obligations.

                  (g) Release of Pledged Collateral. The Agent may release any
         of the Pledged Collateral from this Pledge Agreement or may substitute
         any of the Pledged Collateral for other Pledged Collateral without
         altering, varying or diminishing in any way the force, effect, lien,
         pledge or security interest of this Pledge Agreement as to any Pledged
         Collateral not expressly released or substituted, and this Pledge
         Agreement shall continue as a first priority lien on all Pledged
         Collateral not expressly released or substituted.

         11. Rights of Required Lenders. All rights of the Agent hereunder, if
not exercised by the Agent, may be exercised by the Required Lenders.

         12. Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, any payments in respect of the Pledgor
Obligations and any proceeds of any Pledged Collateral, when received by the
Agent or any of the Lenders in cash or its equivalent, will be applied in
reduction of the Pledgor Obligations in the order set forth in Section 3.15(b)
of the Credit Agreement, and each Pledgor irrevocably waives the right to direct
the application of such payments and proceeds and acknowledges and agrees that
the Agent shall have the continuing and exclusive right to apply and reapply any
and all such payments and proceeds in the Agent's sole discretion,
notwithstanding any entry to the contrary upon any of its books and records.

         13. Costs of Counsel. At all times hereafter, the Pledgors agree to
promptly pay upon demand any and all reasonable costs and expenses of the Agent
or the Lenders, (a) as required under Section 11.5 of the Credit Agreement and
(b) as necessary to protect the Pledged Collateral or to exercise any rights or
remedies under this Pledge Agreement or with respect to any Pledged Collateral.
All of the foregoing costs and expenses shall constitute Pledgor Obligations
hereunder.

         14.      Continuing Agreement.

                  (a) This Pledge Agreement shall be a continuing agreement in
         every respect and shall remain in full force and effect so long as any
         of the Pledgor Obligations remain outstanding or any Credit Document or
         Hedging Agreement is in effect or any Letter of Credit shall remain
         outstanding, and until all of the Commitments thereunder shall have
         terminated (other than any obligations with respect to the indemnities
         and the representations and warranties set forth in the Credit
         Documents). Upon such payment and 



                                      -8-



         termination, this Pledge Agreement shall be automatically terminated
         and the Agent and the Lenders shall, upon the request and at the
         expense of the Pledgors, forthwith release all of its liens and
         security interests hereunder and shall executed and deliver all UCC
         termination statements and/or other documents reasonably requested by
         the Pledgors evidencing such termination. Notwithstanding the
         foregoing all releases and indemnities provided hereunder shall
         survive termination of this Pledge Agreement.

                  (b) This Pledge Agreement shall continue to be effective or be
         automatically reinstated, as the case may be, if at any time payment,
         in whole or in part, of any of the Pledgor Obligations is rescinded or
         must otherwise be restored or returned by the Agent or any Lender as a
         preference, fraudulent conveyance or otherwise under any bankruptcy,
         insolvency or similar law, all as though such payment had not been
         made; provided that in the event payment of all or any part of the
         Pledgor Obligations is rescinded or must be restored or returned, all
         reasonable costs and expenses (including without limitation any
         reasonable legal fees and disbursements) incurred by the Agent or any
         Lender in defending and enforcing such reinstatement shall be deemed to
         be included as a part of the Pledgor Obligations.

         15. Amendments; Waivers; Modifications. This Pledge Agreement and the
provisions hereof may not be amended, waived, modified, changed, discharged or
terminated except as set forth in Section 11.6 of the Credit Agreement.

         16. Successors in Interest. This Pledge Agreement shall create a
continuing security interest in the Collateral and shall be binding upon each
Pledgor, its successors and assigns and shall inure, together with the rights
and remedies of the Agent and the Lenders hereunder, to the benefit of the Agent
and the Lenders and their successors and permitted assigns; provided, however,
that none of the Pledgors may assign its rights or delegate its duties hereunder
without the prior written consent of each Lender or the Required Lenders, as
required by the Credit Agreement. To the fullest extent permitted by law, each
Pledgor hereby releases the Agent and each Lender, and its successors and
assigns, from any liability for any act or omission relating to this Pledge
Agreement or the Collateral, except for any liability arising from the gross
negligence or willful misconduct of the Agent, or such Lender, or its officers,
employees or agents.

         17. Notices. All notices required or permitted to be given under this
Pledge Agreement shall be in conformance with Section 11.1 of the Credit
Agreement.

         18. Counterparts. This Pledge Agreement may be executed in any number
of counterparts, each of which where so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument. It
shall not be necessary in making proof of this Pledge Agreement to produce or
account for more than one such counterpart.

         19. Headings. The headings of the sections and subsections hereof are
provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Pledge Agreement.

         20.      Governing Law; Submission to Jurisdiction; Venue.

                  (a) THIS PLEDGE AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
         THE PARTIES HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND
         INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. Any
         legal action or proceeding with respect to this Security Agreement may
         be brought in the courts of the State of North Carolina, or of the
         United States for the Western District of North Carolina, and, by
         execution and delivery of this Security Agreement, each Pledgor hereby
         irrevocably accepts for itself and in respect of its property,
         generally and unconditionally, the jurisdiction of such courts. Each
         Pledgor further irrevocably consents to the service of process out of
         any of the aforementioned courts in any such action or proceeding by
         the mailing of copies thereof by registered or certified mail, postage
         prepaid, to it at the address for notices pursuant to Section 11.1 of
         the Credit Agreement, such service to become effective 30 days after
         such mailing. Nothing herein shall affect the right of the Agent to
         serve process in any other manner permitted by law or to commence legal
         proceedings or to otherwise proceed against any Pledgor in any other
         jurisdiction.



                                      -9-







                  (b) Each Pledgor hereby irrevocably waives any objection which
         it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Pledge Agreement brought in the courts referred to in subsection
         (a) hereof and hereby further irrevocably waives and agrees not to
         plead or claim in any such court that any such action or proceeding
         brought in any such court has been brought in an inconvenient forum.

         21. Waiver of Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE LAW,
EACH OF THE PARTIES TO THIS PLEDGE AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT
TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR
RELATING TO THIS PLEDGE AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         22. Severability. If any provision of any of the Pledge Agreement is
determined to be illegal, invalid or unenforceable, such provision shall be
fully severable and the remaining provisions shall remain in full force and
effect and shall be construed without giving effect to the illegal, invalid or
unenforceable provisions.

         23. Entirety. This Pledge Agreement, the other Credit Documents and the
Hedging Agreements represent the entire agreement of the parties hereto and
thereto, and supersede all prior agreements and understandings, oral or written,
if any, including any commitment letters or correspondence relating to the
Credit Documents, the Hedging Agreements or the transactions contemplated herein
and therein.

         24. Survival. All representations and warranties of the Pledgors
hereunder shall survive the execution and delivery of this Pledge Agreement, the
other Credit Documents and the Hedging Agreements, the delivery of the Notes and
the making of the Loans and the issuance of the Letters of Credit under the
Credit Agreement.

         25. Other Security. To the extent that any of the Pledgor Obligations
are now or hereafter secured by property other than the Pledged Collateral
(including, without limitation, real and other personal property owned by a
Pledgor), or by a guarantee, endorsement or property of any other Person, then
the Agent and the Lenders shall have the right to proceed against such other
property, guarantee or endorsement upon the occurrence of any Event of Default,
and the Agent and the Lenders have the right, in their sole discretion, to
determine which rights, security, liens, security interests or remedies the
Agent and the Lenders shall at any time pursue, relinquish, subordinate, modify
or take with respect thereto, without in any way modifying or affecting any of
them or any of the Agent's and the Lenders' rights or the Pledgor Obligations
under this Pledge Agreement, under any other of the Credit Documents or under
any Hedging Agreement.

         26.      Joint and Several Obligations of Pledgors.

                  (a) Each of the Pledgors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under the Credit Agreement, for the mutual
         benefit, directly and indirectly, of each of the Pledgors and in
         consideration of the undertakings of each of the Pledgors to accept
         joint and several liability for the obligations of each of them.

                  (b) Each of the Pledgors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Pledgors with respect to the payment and performance of all of the
         Pledgor Obligations arising under this Pledge Agreement, the other
         Credit Documents and the Hedging Agreements, it being the intention of
         the parties hereto that all the Pledgor Obligations shall be the joint
         and several obligations of each of the Pledgors without preferences or
         distinction among them.

                  (c) Notwithstanding any provision to the contrary contained
         herein or in any other of the Credit Documents, to the extent the
         obligations of a Guarantor shall be adjudicated to be invalid or
         unenforceable for any reason (including, without limitation, because of
         any applicable state or federal law relating to fraudulent conveyances
         or transfers) then the obligations of each Guarantor hereunder shall be



                                      -10-



         limited to the maximum amount that is permissible under applicable law
         (whether federal or state and including, without limitation, the
         Bankruptcy Code).

acknowledge and agree that the security interest created hereby in the

         3.       Provisions Relating to Accounts.

                  (a) Anything herein to the contrary notwithstanding, each of
         the Obligors shall remain liable under each of the Accounts to observe
         and perform all the conditions and obligations to be observed and
         performed by it thereunder, all in accordance with the terms of any
         agreement giving rise to each such Account. Neither the Agent nor any
         Lender shall have any obligation or liability under any Account (or any
         agreement giving rise thereto) by reason of or arising out of this
         Security Agreement or the receipt by the Agent or any Lender of any
         payment relating to such Account pursuant hereto, nor shall the Agent
         or any Lender be obligated in any manner to perform any of the
         obligations of an Obligor under or pursuant to any Account (or any
         agreement giving rise thereto), to make any payment, to make any
         inquiry as to the nature or the sufficiency of any payment received by
         it or as to the sufficiency of any performance by any party under any
         Account (or any agreement giving rise thereto), to present or file any
         claim, to take any action to enforce any performance or to collect the
         payment of any amounts which may have been assigned to it or to which
         it may be entitled at any time or times.

                  (b) Once during each calendar year (upon reasonable notice) or
         at any time after the occurrence and during the continuation of an
         Event of Default, the Agent shall have the right, but not the
         obligation, during normal business hours, to make test verifications of
         the Accounts in any manner and through any medium that it reasonably
         considers advisable, and the Obligors shall furnish all such assistance
         and information as the Agent may require in connection with such test
         verifications. At any time and from time to time, upon the Agent's
         request and at the expense of the Obligors, the Obligors shall cause
         independent public accountants or others satisfactory to the Agent to
         furnish to the Agent reports showing reconciliations, aging 



                                      -3-



         and test verifications of, and trial balances for, the Accounts. The
         Agent in its own name or in the name of others may communicate with
         account debtors on the Accounts to verify with them to the Agent's
         satisfaction the existence, amount and terms of any Accounts.

         4. Representations and Warranties. Each Obligor hereby represents and
warrants to the Agent, for the benefit of the Lenders, that so long as any of
the Secured Obligations remain outstanding or any Credit Document or Hedging
Agreement is in effect or any Letter of Credit shall remain outstanding, and
until all of the Commitments shall have been terminated:

                  (a) Chief Executive Office; Books & Records. Each Obligor's
         chief executive office and chief place of business is (and for the
         prior four months have been) located at the locations set forth on
         Schedule 4(a) hereto, and each Obligor keeps its books and records at
         such locations.

                  (b) Location of Collateral. The location of all Collateral
         owned by each Obligor is as shown on Schedule 4(b) hereto.

                  (c) Ownership. Each Obligor is the legal and beneficial owner
         of its Collateral and has the right to pledge, sell, assign or transfer
         the same. Each Obligor's legal name is as shown in this Security
         Agreement and no Obligor has in the past four months changed its name,
         been party to a merger, consolidation or other change in structure or
         used any tradename except as set forth in Schedule 4(c) attached
         hereto.

                  (d) Security Interest/Priority. This Security Agreement
         creates a valid security interest in favor of the Agent, for the
         benefit of the Lenders, in the Collateral of such Obligor and, when
         properly perfected by filing, shall constitute a valid perfected
         security interest in such Collateral, to the extent such security can
         be perfected by filing under the UCC, free and clear of all Liens
         except for Permitted Liens.

                  (e) Farm Products. None of the Collateral constitutes, or is
         the Proceeds of, Farm Products.

                  (f) Accounts. (i) Each Account of the Obligors and the papers
         and documents relating thereto are genuine and in all material respects
         what they purport to be, (ii) each Account arises out of (A) a bona
         fide sale of goods sold and delivered by such Obligor (or is in the
         process of being delivered) or (B) services theretofore actually
         rendered by such Obligor to, the account debtor named therein, (iii) no
         Account of an Obligor is evidenced by any Instrument or Chattel Paper
         unless such Instrument or Chattel Paper has been theretofore endorsed
         over and delivered to the Agent and (iv) no surety bond was required or
         given in connection with any Account of an Obligor or the contracts or
         purchase orders out of which they arose.

                  (g) Inventory. No Inventory is held by an Obligor pursuant to
         consignment, sale or return, sale on approval or similar arrangement.

                  (h)      Copyrights, Patents and Trademarks.

                                    (i) Schedule 1(b) hereto includes all
                  Copyrights, Copyright Licenses, Patents, Patent Licenses,
                  Trademarks and Trademark Licenses owned by the Obligors in
                  their own names as of the date hereof.

                                    (ii) To the best of each Obligor's
                  knowledge, each Copyright, Patent and Trademark of such
                  Obligor is valid, subsisting, unexpired, enforceable and has
                  not been abandoned.

                                    (iii) Except as set forth in Schedule 1(b)
                  hereto, none of such Copyrights, Patents and Trademarks is the
                  subject of any licensing or franchise agreement.



                                      -4-



                                    (iv) No holding, decision or judgment has
                  been rendered by any Governmental Authority which would limit,
                  cancel or question the validity of any Copyright, Patent or
                  Trademark.

                                    (v) No action or proceeding is pending
                  seeking to limit, cancel or question the validity of any
                  Copyright, Patent or Trademark, or which, if adversely
                  determined, would have a material adverse effect on the value
                  of any Copyright, Patent or Trademark.

                                    (vi) All applications pertaining to the
                  Copyrights, Patents and Trademarks of each Obligor have been
                  duly and properly filed, and all registrations or letters
                  pertaining to such Copyrights, Patents and Trademarks have
                  been duly and properly filed and issued, and all of such
                  Copyrights, Patents and Trademarks are valid and enforceable.

                                    (vii) No Obligor has made any assignment or
                  agreement in conflict with the security interest in the
                  Copyrights, Patents or Trademarks of each Obligor hereunder.

         5. Covenants. Each Obligor covenants that, so long as any of the
Secured Obligations remain outstanding or any Credit Document or Hedging
Agreement is in effect or any Letter of Credit shall remain outstanding, and
until all of the Commitments shall have been terminated, such Obligor shall:

                  (a) Other Liens. Defend the Collateral against the claims and
         demands of all other parties claiming an interest therein, keep the
         Collateral free from all Liens, except for Permitted Liens, and not
         sell, exchange, transfer, assign, lease or otherwise dispose of the
         Collateral or any interest therein, except as permitted under the
         Credit Agreement.

                  (b) Preservation of Collateral. Keep the Collateral in good
         order, condition and repair and not use the Collateral in violation of
         the provisions of this Security Agreement or any other agreement
         relating to the Collateral or any policy insuring the Collateral or any
         applicable statute, law, bylaw, rule, regulation or ordinance.

                  (c) Instruments/Chattel Paper. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced
         by any Instrument or Chattel Paper, immediately deliver such Instrument
         or Chattel Paper to the Agent, duly indorsed in a manner satisfactory
         to the Agent, to be held as Collateral pursuant to this Security
         Agreement.

                  (d) Change in Location. Not, without providing 30 days prior
         written notice to the Agent and without filing such amendments to any
         previously filed financing statements as the Agent may require, (a)
         change the location of its chief executive office and chief place of
         business (as well as its books and records) from the locations set
         forth on Schedule 4(a) hereto, (b) change the location of its
         Collateral from the locations set forth for such Obligor on Schedule
         4(b) hereto, or (c) change its name, be party to a merger,
         consolidation or other change in structure or use any tradename other
         than as set forth on Schedule 4(c) attached hereto.

                  (e) Inspection. Upon reasonable notice, and during reasonable
         hours, at all times allow the Agent or its representatives to visit and
         inspect the Collateral as set forth in Section 7.10 of the Credit
         Agreement.

                  (f) Perfection of Security Interest. Execute and deliver to
         the Agent such agreements, assignments or instruments (including
         affidavits, notices, reaffirmations and amendments and restatements of
         existing documents, as the Agent may reasonably request) and do all
         such other things as the Agent may reasonably deem necessary or
         appropriate (i) to assure to the Agent its security interests
         hereunder, including (A) such financing statements (including renewal
         statements) or amendments thereof or supplements thereto or other
         instruments as the Agent may from time to time reasonably request in
         order to perfect and maintain the security interests granted hereunder
         in accordance with the UCC, (B) with regard to Copyrights, a Notice 



                                      -5-



         of Grant of Security Interest in Copyrights in the form of Schedule
         5(f)(i), (C) with regard to Patents, a Notice of Grant of Security
         Interest in Patents for filing with the United States Patent and
         Trademark Office in the form of Schedule 5(f)(ii) attached hereto and
         (D) with regard to Trademarks, a Notice of Grant of Security Interest
         in Trademarks for filing with the United States Patent and Trademark
         Office in the form of Schedule 5(f)(iii) attached hereto, (ii) to
         consummate the transactions contemplated hereby and (iii) to otherwise
         protect and assure the Agent of its rights and interests hereunder. To
         that end, each Obligor agrees that the Agent may file one or more
         financing statements disclosing the Agent's security interest in any
         or all of the Collateral of such Obligor without, to the extent
         permitted by law, such Obligor's signature thereon, and further each
         Obligor also hereby irrevocably makes, constitutes and appoints the
         Agent, its nominee or any other person whom the Agent may designate,
         as such Obligor's attorney in fact with full power and for the limited
         purpose to sign in the name of such Obligor any such financing
         statements, or amendments and supplements to financing statements,
         renewal financing statements, notices or any similar documents which
         in the Agent's reasonable discretion would be necessary, appropriate
         or convenient in order to perfect and maintain perfection of the
         security interests granted hereunder, such power, being coupled with
         an interest, being and remaining irrevocable so long as the Credit
         Agreement is in effect or any amounts payable thereunder or under any
         other Credit Document, any Letter of Credit or any Hedging Agreement
         shall remain outstanding, and until all of the Commitments thereunder
         shall have terminated. Each Obligor hereby agrees that a carbon,
         photographic or other reproduction of this Security Agreement or any
         such financing statement is sufficient for filing as a financing
         statement by the Agent without notice thereof to such Obligor wherever
         the Agent may in its sole discretion desire to file the same. In the
         event for any reason the law of any jurisdiction other than New York
         becomes or is applicable to the Collateral of any Obligor or any part
         thereof, or to any of the Secured Obligations, such Obligor agrees to
         execute and deliver all such instruments and to do all such other
         things as the Agent in its sole discretion reasonably deems necessary
         or appropriate to preserve, protect and enforce the security interests
         of the Agent under the law of such other jurisdiction (and, if an
         Obligor shall fail to do so promptly upon the request of the Agent,
         then the Agent may execute any and all such requested documents on
         behalf of such Obligor pursuant to the power of attorney granted
         hereinabove). If any Collateral is in the possession or control of an
         Obligor's agents and the Agent so requests, such Obligor agrees to
         notify such agents in writing of the Agent's security interest therein
         and, upon the Agent's request, instruct them to hold all such
         Collateral for the Lenders' account and subject to the Agent's
         instructions. Each Obligor agrees to mark its books and records to
         reflect the security interest of the Agent in the Collateral.

                  (g) Treatment of Accounts. Not grant or extend the time for
         payment of any Account, or compromise or settle any Account for less
         than the full amount thereof, or release any person or property, in
         whole or in part, from payment thereof, or allow any credit or discount
         thereon, other than as normal and customary in the ordinary course of
         an Obligor's business.

                  (h)      Covenants Relating to Copyrights.

                                    (i) Employ the Copyright for each Work with
                  such notice of copyright as may be required by law to secure
                  copyright protection.

                                    (ii) Not do any act or knowingly omit to do
                  any act whereby any material Copyright may become invalidated
                  and (A) not do any act, or knowingly omit to do any act,
                  whereby any material Copyright may become injected into the
                  public domain; (B) notify the Agent immediately if it knows,
                  or has reason to know, that any material Copyright may become
                  injected into the public domain or of any adverse
                  determination or development (including, without limitation,
                  the institution of, or any such determination or development
                  in, any court or tribunal in the United States or any other
                  country) regarding an Obligor's ownership of any such
                  Copyright or its validity; (C) take all necessary steps as it
                  shall deem appropriate under the circumstances, to maintain
                  and pursue each application (and to obtain the relevant
                  registration) and to maintain each registration of each
                  material Copyright owned by an Obligor including, without
                  limitation, filing of applications for renewal where
                  necessary; and (D) promptly notify the Agent of any material
                  infringement of any material Copyright of an Obligor of which
                  it becomes aware and take such actions as it shall 



                                      -6-



                  reasonably deem appropriate under the circumstances to
                  protect such Copyright, including, where appropriate, the
                  bringing of suit for infringement, seeking injunctive relief
                  and seeking to recover any and all damages for such
                  infringement.

                                    (iii) Not make any assignment or agreement
                  in conflict with the security interest in the Copyrights of
                  each Obligor hereunder.

                  (i)      Covenants Relating to Patents and Trademarks.

                                    (i) (A) Continue to use each Trademark on
                  each and every trademark class of goods applicable to its
                  current line as reflected in its current catalogs, brochures
                  and price lists in order to maintain such Trademark in full
                  force free from any claim of abandonment for non-use, (B)
                  maintain as in the past the quality of products and services
                  offered under such Trademark, (C) employ such Trademark with
                  the appropriate notice of registration, (D) not adopt or use
                  any mark which is confusingly similar or a colorable imitation
                  of such Trademark unless the Agent, for the ratable benefit of
                  the Lenders, shall obtain a perfected security interest in
                  such mark pursuant to this Security Agreement, and (E) not
                  (and not permit any licensee or sublicensee thereof to) do any
                  act or knowingly omit to do any act whereby any Trademark may
                  become invalidated.

                                    (ii) Not do any act, or omit to do any act,
                  whereby any Patent may become abandoned or dedicated.

                                    (iii) Notify the Agent and the Lenders
                  immediately if it knows, or has reason to know, that any
                  application or registration relating to any Patent or
                  Trademark may become abandoned or dedicated, or of any adverse
                  determination or development (including, without limitation,
                  the institution of, or any such determination or development
                  in, any proceeding in the United States Patent and Trademark
                  Office or any court or tribunal in any country) regarding an
                  Obligor's ownership of any Patent or Trademark or its right to
                  register the same or to keep and maintain the same.

                                    (iv) Whenever an Obligor, either by itself
                  or through an agent, employee, licensee or designee, shall
                  file an application for the registration of any Patent or
                  Trademark with the United States Patent and Trademark Office
                  or any similar office or agency in any other country or any
                  political subdivision thereof, an Obligor shall report such
                  filing to the Agent and the Lenders within five Business Days
                  after the last day of the fiscal quarter in which such filing
                  occurs. Upon request of the Agent, an Obligor shall execute
                  and deliver any and all agreements, instruments, documents and
                  papers as the Agent may request to evidence the Agent's and
                  the Lenders' security interest in any Patent or Trademark and
                  the goodwill and general intangibles of an Obligor relating
                  thereto or represented thereby.

                                    (v) Take all reasonable and necessary steps,
                  including, without limitation, in any proceeding before the
                  United States Patent and Trademark Office, or any similar
                  office or agency in any other country or any political
                  subdivision thereof, to maintain and pursue each application
                  (and to obtain the relevant registration) and to maintain each
                  registration of the Patents and Trademarks, including, without
                  limitation, filing of applications for renewal, affidavits of
                  use and affidavits of incontestability.

                                    (vi) Promptly notify the Agent and the
                  Lenders after it learns that any Patent or Trademark included
                  in the Collateral is infringed, misappropriated or diluted by
                  a third party and promptly sue for infringement,
                  misappropriation or dilution, to seek injunctive relief where
                  appropriate and to recover any and all damages for such
                  infringement, misappropriation or dilution, or take such other
                  actions as it shall reasonably deem appropriate under the
                  circumstances to protect such Patent or Trademark.



                                      -7-



                                    (vii) Not make any assignment or agreement
                  in conflict with the security interest in the Patents or
                  Trademarks of each Obligor hereunder.

                  (j) New Patents, Copyrights and Trademarks. Promptly provide
         the Agent with (i) a listing of all applications, if any, for new
         Copyrights, Patents or Trademarks (together with a listing of the
         issuance of registrations or letters on present applications), which
         new applications and issued registrations or letters shall be subject
         to the terms and conditions hereunder, and (ii) (A) with respect to
         Copyrights, a duly executed Notice of Security Interest in Copyrights,
         (B) with respect to Patents, a duly executed Notice of Security
         Interest in Patents, (C) with respect to Trademarks, a duly executed
         Notice of Security Interest in Trademarks or (D) such other duly
         executed documents as the Agent may request in a form acceptable to
         counsel for the Agent and suitable for recording to evidence the
         security interest in the Copyright, Patent or Trademark which is the
         subject of such new application.

                  (k) Insurance. Insure, repair and replace the Collateral of
         such Obligor as set forth in the Credit Agreement. All insurance
         proceeds shall be subject to the security interest of the Agent
         hereunder.

         6. Advances by Lenders. On failure of any Obligor to perform any of the
covenants and agreements contained herein, the Agent may, at its sole option and
in its sole discretion, perform the same and in so doing may expend such sums as
the Agent may reasonably deem advisable in the performance thereof, including,
without limitation, the payment of any insurance premiums, the payment of any
taxes, a payment to obtain a release of a Lien or potential Lien, expenditures
made in defending against any adverse claim and all other expenditures which the
Agent or the Lenders may make for the protection of the security hereof or which
may be compelled to make by operation of law. All such sums and amounts so
expended shall be repayable by the Obligors on a joint and several basis
promptly upon timely notice thereof and demand therefor, shall constitute
additional Secured Obligations and shall bear interest from the date said
amounts are expended at the default rate specified in Section 3.1 of the Credit
Agreement for Revolving Loans that are Base Rate Loans. No such performance of
any covenant or agreement by the Agent or the Lenders on behalf of any Obligor,
and no such advance or expenditure therefor, shall relieve the Obligors of any
default under the terms of this Security Agreement, the other Credit Documents
or any Hedging Agreement. The Lenders may make any payment hereby authorized in
accordance with any bill, statement or estimate procured from the appropriate
public office or holder of the claim to be discharged without inquiry into the
accuracy of such bill, statement or estimate or into the validity of any tax
assessment, sale, forfeiture, tax lien, title or claim except to the extent such
payment is being contested in good faith by an Obligor in appropriate
proceedings and against which adequate reserves are being maintained in
accordance with GAAP.

         7.       Events of Default.

         The occurrence of an event which under the Credit Agreement would
constitute an Event of Default shall be an Event of Default hereunder (an "Event
of Default").

         8.       Remedies.

                  (a) General Remedies. Upon the occurrence of an Event of
         Default and during continuation thereof, the Lenders shall have, in
         addition to the rights and remedies provided herein, in the Credit
         Documents, in the Hedging Agreements or by law (including, but not
         limited to, the rights and remedies set forth in the Uniform Commercial
         Code of the jurisdiction applicable to the affected Collateral), the
         rights and remedies of a secured party under the UCC (regardless of
         whether the UCC is the law of the jurisdiction where the rights and
         remedies are asserted and regardless of whether the UCC applies to the
         affected Collateral), and further, the Agent may, with or without
         judicial process or the aid and assistance of others, (i) enter on any
         premises on which any of the Collateral may be located and, without
         resistance or interference by the Obligors, take possession of the
         Collateral, (ii) dispose of any Collateral on any such premises, (iii)
         require the Obligors to assemble and make available to the Agent at the
         expense of the Obligors any Collateral at any place and time designated
         by the Agent which is reasonably convenient to both parties, (iv)
         remove any 



                                      -8-



         Collateral from any such premises for the purpose of effecting sale or
         other disposition thereof, and/or (v) without demand and without
         advertisement, notice, hearing or process of law, all of which each of
         the Obligors hereby waives to the fullest extent permitted by law, at
         any place and time or times, sell and deliver any or all Collateral
         held by or for it at public or private sale, by one or more contracts,
         in one or more parcels, for cash, upon credit or otherwise, at such
         prices and upon such terms as the Agent deems advisable, in its sole
         discretion (subject to any and all mandatory legal requirements). In
         addition to all other sums due the Agent and the Lenders with respect
         to the Secured Obligations, the Obligors shall pay the Agent and each
         of the Lenders all reasonable documented costs and expenses incurred
         by the Agent or any such Lender, including, but not limited to,
         reasonable attorneys' fees and court costs, in obtaining or
         liquidating the Collateral, in enforcing payment of the Secured
         Obligations, or in the prosecution or defense of any action or
         proceeding by or against the Agent or the Lenders or the Obligors
         concerning any matter arising out of or connected with this Security
         Agreement, any Collateral or the Secured Obligations, including,
         without limitation, any of the foregoing arising in, arising under or
         related to a case under the Bankruptcy Code. To the extent the rights
         of notice cannot be legally waived hereunder, each Obligor agrees that
         any requirement of reasonable notice shall be met if such notice is
         personally served on or mailed, postage prepaid, to the Borrower in
         accordance with the notice provisions of Section 11.1 of the Credit
         Agreement at least 10 days before the time of sale or other event
         giving rise to the requirement of such notice. The Agent and the
         Lenders shall not be obligated to make any sale or other disposition
         of the Collateral regardless of notice having been given. To the
         extent permitted by law, any Lender may be a purchaser at any such
         sale. To the extent permitted by applicable law, each of the Obligors
         hereby waives all of its rights of redemption with respect to any such
         sale. Subject to the provisions of applicable law, the Agent and the
         Lenders may postpone or cause the postponement of the sale of all or
         any portion of the Collateral by announcement at the time and place of
         such sale, and such sale may, without further notice, to the extent
         permitted by law, be made at the time and place to which the sale was
         postponed, or the Agent and the Lenders may further postpone such sale
         by announcement made at such time and place.

                  (b) Remedies relating to Accounts. Upon the occurrence of an
         Event of Default and during the continuation thereof, whether or not
         the Agent has exercised any or all of its rights and remedies
         hereunder, each Obligor will promptly upon request of the Agent
         instruct all account debtors to remit all payments in respect of
         Accounts to a mailing location selected by the Agent. In addition, the
         Agent or its designee may notify any Obligor's customers and account
         debtors that the Accounts of such Obligor have been assigned to the
         Agent or of the Agent's security interest therein, and may (either in
         its own name or in the name of an Obligor or both) demand, collect
         (including without limitation by way of a lockbox arrangement),
         receive, take receipt for, sell, sue for, compound, settle, compromise
         and give acquittance for any and all amounts due or to become due on
         any Account, and, in the Agent's discretion, file any claim or take any
         other action or proceeding to protect and realize upon the security
         interest of the Lenders in the Accounts. Each Obligor acknowledges and
         agrees that the Proceeds of its Accounts remitted to or on behalf of
         the Agent in accordance with the provisions hereof shall be solely for
         the Agent's own convenience and that such Obligor shall not have any
         right, title or interest in such Accounts or in any such other amounts
         except as expressly provided herein. The Agent and the Lenders shall
         have no liability or responsibility to any Obligor for acceptance of a
         check, draft or other order for payment of money bearing the legend
         "payment in full" or words of similar import or any other restrictive
         legend or endorsement or be responsible for determining the correctness
         of any remittance. Each Obligor hereby agrees to indemnify the Agent
         and the Lenders from and against all liabilities, damages, losses,
         actions, claims, judgments, costs, expenses, charges and reasonable
         attorneys' fees suffered or incurred by the Agent or the Lenders (each,
         an "Indemnified Party") because of the maintenance of the foregoing
         arrangements except as relating to or arising out of the gross
         negligence or willful misconduct of an Indemnified Party or its
         officers, employees or agents. In the case of any investigation,
         litigation or other proceeding, the foregoing indemnity shall be
         effective whether or not such investigation, litigation or proceeding
         is brought by an Obligor, its directors, shareholders or creditors or
         an Indemnified Party or any other Person or any other Indemnified Party
         is otherwise a party thereto.

                  (c) Access. In addition to the rights and remedies hereunder,
         upon the occurrence of an Event of Default and during the continuance
         thereof, the Agent shall have the right to enter and remain upon the



                                      -9-



         various premises of the Obligors without cost or charge to the Agent,
         and use the same, together with materials, supplies, books and records
         of the Obligors for the purpose of collecting and liquidating the
         Collateral, or for preparing for sale and conducting the sale of the
         Collateral, whether by foreclosure, auction or otherwise. In addition,
         the Agent may remove Collateral, or any part thereof, from such
         premises and/or any records with respect thereto, in order to
         effectively collect or liquidate such Collateral.

                  (d) Nonexclusive Nature of Remedies. Failure by the Agent or
         the Lenders to exercise any right, remedy or option under this Security
         Agreement, any other Credit Document, any Hedging Agreement or as
         provided by law, or any delay by the Agent or the Lenders in exercising
         the same, shall not operate as a waiver of any such right, remedy or
         option. No waiver hereunder shall be effective unless it is in writing,
         signed by the party against whom such waiver is sought to be enforced
         and then only to the extent specifically stated, which in the case of
         the Agent or the Lenders shall only be granted as provided herein. To
         the extent permitted by law, neither the Agent, the Lenders, nor any
         party acting as attorney for the Agent or the Lenders, shall be liable
         hereunder for any acts or omissions or for any error of judgment or
         mistake of fact or law other than their gross negligence or willful
         misconduct hereunder. The rights and remedies of the Agents and the
         Lenders under this Security Agreement shall be cumulative and not
         exclusive of any other right or remedy which the Agent or the Lenders
         may have.

                  (e) Retention of Collateral. The Agent may, after providing
         the notices required by Section 9-505(2) of the UCC or otherwise
         complying with the requirements of applicable law of the relevant
         jurisdiction, to the extent the Agent is in possession of any of the
         Collateral, retain the Collateral in satisfaction of the Secured
         Obligations. Unless and until the Agent shall have provided such
         notices, however, the Agent shall not be deemed to have retained any
         Collateral in satisfaction of any Secured Obligations for any reason.

                  (f) Deficiency. In the event that the proceeds of any sale,
         collection or realization are insufficient to pay all amounts to which
         the Agent or the Lenders are legally entitled, the Obligors shall be
         jointly and severally liable for the deficiency, together with interest
         thereon at the default rate specified in Section 3.1 of the Credit
         Agreement for Revolving Loans that are Base Rate Loans, together with
         the costs of collection and the reasonable fees of any attorneys
         employed by the Agent to collect such deficiency. Any surplus remaining
         after the full payment and satisfaction of the Secured Obligations
         shall be returned to the Obligors or to whomsoever a court of competent
         jurisdiction shall determine to be entitled thereto.

         9. Rights of the Agent.

                  (a) Power of Attorney. In addition to other powers of attorney
         contained herein, each Obligor hereby designates and appoints the
         Agent, on behalf of the Lenders, and each of its designees or agents,
         as attorney-in-fact of such Obligor, irrevocably and with power of
         substitution, with authority to take any or all of the following
         actions upon the occurrence and during the continuance of an Event of
         Default:

                           (i) to demand, collect, settle, compromise, adjust,
                  give discharges and releases, all as the Agent may reasonably
                  determine;

                           (ii) to commence and prosecute any actions at any
                  court for the purposes of collecting any Collateral and
                  enforcing any other right in respect thereof;

                           (iii) to defend, settle or compromise any action
                  brought and, in connection therewith, give such discharge or
                  release as the Agent may deem reasonably appropriate;

                           (iv) receive, open and dispose of mail addressed to
                  an Obligor and endorse checks, notes, drafts, acceptances,
                  money orders, bills of lading, warehouse receipts or other
                  instruments or documents evidencing payment, shipment or
                  storage of the goods giving rise to the Collateral of such
                  Obligor on behalf of and in the name of such Obligor, or
                  securing, or relating to such Collateral;



                                      -10-



                           (v) sell, assign, transfer, make any agreement in
                  respect of, or otherwise deal with or exercise rights in
                  respect of, any Collateral or the goods or services which have
                  given rise thereto, as fully and completely as though the Bank
                  were the absolute owner thereof for all purposes;

                           (vi) adjust and settle claims under any insurance
                  policy relating thereto;

                           (vii) execute and deliver all assignments,
                  conveyances, statements, financing statements, renewal
                  financing statements, security agreements, affidavits, notices
                  and other agreements, instruments and documents that the Agent
                  may determine necessary in order to perfect and maintain the
                  security interests and liens granted in this Security
                  Agreement and in order to fully consummate all of the
                  transactions contemplated therein;

                           (viii) institute any foreclosure proceedings that the
                  Agent may deem appropriate; and

                           (ix) do and perform all such other acts and things as
                  the Agent may reasonably deem to be necessary, proper or
                  convenient in connection with the Collateral.

         This power of attorney is a power coupled with an interest and shall be
         irrevocable (i) for so long as any of the Secured Obligations remain
         outstanding, any Credit Document or any Hedging Agreement is in effect
         or any Letter of Credit shall remain outstanding and (ii) until all of
         the Commitments shall have been terminated. The Agent shall be under no
         duty to exercise or withhold the exercise of any of the rights, powers,
         privileges and options expressly or implicitly granted to the Agent in
         this Security Agreement, and shall not be liable for any failure to do
         so or any delay in doing so. The Agent shall not be liable for any act
         or omission or for any error of judgment or any mistake of fact or law
         in its individual capacity or its capacity as attorney-in-fact except
         acts or omissions resulting from its gross negligence or willful
         misconduct. This power of attorney is conferred on the Agent solely to
         protect, preserve and realize upon its security interest in the
         Collateral.

                  (b) Performance by the Agent of Obligations. If any Obligor
         fails to perform any agreement or obligation contained herein, the
         Agent itself may perform, or cause performance of, such agreement or
         obligation, and the expenses of the Agent incurred in connection
         therewith shall be payable by the Obligors on a joint and several basis
         pursuant to Section 11 hereof.

                  (c) Assignment by the Agent. The Agent may from time to time
         assign the Secured Obligations and any portion thereof and/or the
         Collateral and any portion thereof, and the assignee shall be entitled
         to all of the rights and remedies of the Agent under this Security
         Agreement in relation thereto.

                  (d) The Agent's Duty of Care. Other than the exercise of
         reasonable care to assure the safe custody of the Collateral while
         being held by the Agent hereunder, the Agent shall have no duty or
         liability to preserve rights pertaining thereto, it being understood
         and agreed that the Obligors shall be responsible for preservation of
         all rights in the Collateral, and the Agent shall be relieved of all
         responsibility for the Collateral upon surrendering it or tendering the
         surrender of it to the Obligors. The Agent shall be deemed to have
         exercised reasonable care in the custody and preservation of the
         Collateral in its possession if the Collateral is accorded treatment
         substantially equal to that which the Agent accords its own property,
         which shall be no less than the treatment employed by a reasonable and
         prudent agent in the industry, it being understood that the Agent shall
         not have responsibility for taking any necessary steps to preserve
         rights against any parties with respect to any of the Collateral.

         10. Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, any payments in respect of the Secured
Obligations and any proceeds of the Collateral, when received by the Agent or
any of the Lenders in cash or its equivalent, will be applied in reduction of
the Secured Obligations in the order set forth 



                                      -11-



in Section 3.15(b) of the Credit Agreement, and each Obligor irrevocably waives
the right to direct the application of such payments and proceeds and
acknowledges and agrees that the Agent shall have the continuing and exclusive
right to apply and reapply any and all such payments and proceeds in the Agent's
sole discretion, notwithstanding any entry to the contrary upon any of its books
and records.

         11. Costs of Counsel. If at any time hereafter, whether upon the
occurrence of an Event of Default or not, the Agent employs counsel to prepare
or consider amendments, waivers or consents with respect to this Security
Agreement, or to take action or make a response in or with respect to any legal
or arbitral proceeding relating to this Security Agreement or relating to the
Collateral, or to protect the Collateral or exercise any rights or remedies
under this Security Agreement or with respect to the Collateral, then the
Obligors agree to promptly pay upon demand any and all such reasonable
documented costs and expenses of the Agent or the Lenders, all of which costs
and expenses shall constitute Secured Obligations hereunder.

         12.      Continuing Agreement.

                  (a) This Security Agreement shall be a continuing agreement in
         every respect and shall remain in full force and effect so long as any
         of the Secured Obligations remain outstanding or any Credit Document or
         Hedging Agreement is in effect or any Letter of Credit shall remain
         outstanding, and until all of the Commitments thereunder shall have
         terminated (other than any obligations with respect to the indemnities
         and the representations and warranties set forth in the Credit
         Documents). Upon such payment and termination, this Security Agreement
         shall be automatically terminated and the Agent and the Lenders shall,
         upon the request and at the expense of the Obligors, forthwith release
         all of its liens and security interests hereunder and shall execute and
         deliver all UCC termination statements and/or other documents
         reasonably requested by the Obligors evidencing such termination.
         Notwithstanding the foregoing all releases and indemnities provided
         hereunder shall survive termination of this Security Agreement.

                  (b) This Security Agreement shall continue to be effective or
         be automatically reinstated, as the case may be, if at any time
         payment, in whole or in part, of any of the Secured Obligations is
         rescinded or must otherwise be restored or returned by the Agent or any
         Lender as a preference, fraudulent conveyance or otherwise under any
         bankruptcy, insolvency or similar law, all as though such payment had
         not been made; provided that in the event payment of all or any part of
         the Secured Obligations is rescinded or must be restored or returned,
         all reasonable costs and expenses (including without limitation any
         reasonable legal fees and disbursements) incurred by the Agent or any
         Lender in defending and enforcing such reinstatement shall be deemed to
         be included as a part of the Secured Obligations.

         13. Amendments; Waivers; Modifications. This Security Agreement and the
provisions hereof may not be amended, waived, modified, changed, discharged or
terminated except as set forth in Section 11.6 of the Credit Agreement.

         14. Successors in Interest. This Security Agreement shall create a
continuing security interest in the Collateral and shall be binding upon each
Obligor, its successors and assigns and shall inure, together with the rights
and remedies of the Agent and the Lenders hereunder, to the benefit of the Agent
and the Lenders and their successors and permitted assigns; provided, however,
that none of the Obligors may assign its rights or delegate its duties hereunder
without the prior written consent of each Lender or the Required Lenders, as
required by the Credit Agreement. To the fullest extent permitted by law, each
Obligor hereby releases the Agent and each Lender, and its successors and
assigns, from any liability for any act or omission relating to this Security
Agreement or the Collateral, except for any liability arising from the gross
negligence or willful misconduct of the Agent, or such Lender, or its officers,
employees or agents.

         15. Notices. All notices required or permitted to be given under this
Security Agreement shall be in conformance with Section 11.1 of the Credit
Agreement.



                                      -12-



         16. Counterparts. This Security Agreement may be executed in any number
of counterparts, each of which where so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument. It
shall not be necessary in making proof of this Security Agreement to produce or
account for more than one such counterpart.

         17. Headings. The headings of the sections and subsections hereof are
provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Security Agreement.

         18.      Governing Law; Submission to Jurisdiction; Venue.

                  (a) THIS SECURITY AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
         THE PARTIES HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND
         INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. Any
         legal action or proceeding with respect to this Security Agreement may
         be brought in the courts of the State of North Carolina, or of the
         United States for the Western District of North Carolina, and, by
         execution and delivery of this Security Agreement, each Obligor hereby
         irrevocably accepts for itself and in respect of its property,
         generally and unconditionally, the jurisdiction of such courts. Each
         Obligor further irrevocably consents to the service of process out of
         any of the aforementioned courts in any such action or proceeding by
         the mailing of copies thereof by registered or certified mail, postage
         prepaid, to it at the address for notices pursuant to Section 11.1 of
         the Credit Agreement, such service to become effective 30 days after
         such mailing. Nothing herein shall affect the right of the Agent to
         serve process in any other manner permitted by law or to commence legal
         proceedings or to otherwise proceed against any Obligor in any other
         jurisdiction.

                  (b) Each Obligor hereby irrevocably waives any objection which
         it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Security Agreement brought in the courts referred to in subsection
         (a) hereof and hereby further irrevocably waives and agrees not to
         plead or claim in any such court that any such action or proceeding
         brought in any such court has been brought in an inconvenient forum.

         19. Waiver of Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE LAW,
EACH OF THE PARTIES TO THIS SECURITY AGREEMENT HEREBY IRREVOCABLY WAIVES ALL
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF
OR RELATING TO THIS SECURITY AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         20. Severability. If any provision of any of the Security Agreement is
determined to be illegal, invalid or unenforceable, such provision shall be
fully severable and the remaining provisions shall remain in full force and
effect and shall be construed without giving effect to the illegal, invalid or
unenforceable provisions.

         21. Entirety. This Security Agreement, the other Credit Documents and
the Hedging Agreements represent the entire agreement of the parties hereto and
thereto, and supersede all prior agreements and understandings, oral or written,
if any, including any commitment letters or correspondence relating to the
Credit Documents, the Hedging Agreements or the transactions contemplated herein
and therein.

         22. Survival. All representations and warranties of the Obligors
hereunder shall survive the execution and delivery of this Security Agreement,
the other Credit Documents and the Hedging Agreements, the delivery of the Notes
and the making of the Loans and the issuance of the Letters of Credit under the
Credit Agreement.

         23. Other Security. To the extent that any of the Secured Obligations
are now or hereafter secured by property other than the Collateral (including,
without limitation, real property and securities owned by an Obligor), or by a
guarantee, endorsement or property of any other Person, then the Agent and the
Lenders shall have the right to proceed against such other property, guarantee
or endorsement upon the occurrence of any Event of Default, and the Agent and
the Lenders have the right, in their sole discretion, to determine which rights,
security, liens, security 



                                      -13-



interests or remedies the Agent and the Lenders shall at any time pursue,
relinquish, subordinate, modify or take with respect thereto, without in any way
modifying or affecting any of them or any of the Agent's and the Lenders' rights
or the Secured Obligations under this Security Agreement, under any other of the
Credit Documents or under any Hedging Agreement.

         24.      Joint and Several Obligations of Obligors.

                  (a) Each of the Obligors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under the Credit Agreement, for the mutual
         benefit, directly and indirectly, of each of the Obligors and in
         consideration of the undertakings of each of the Obligors to accept
         joint and several liability for the obligations of each of them.

                  (b) Each of the Obligors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Obligors with respect to the payment and performance of all of the
         Secured Obligations arising under this Security Agreement, the other
         Credit Documents and the Hedging Agreements, it being the intention of
         the parties hereto that all the Obligations shall be the joint and
         several obligations of each of the Obligors without preferences or
         distinction among them.

                  (c) Notwithstanding any provision to the contrary contained
         herein or in any other of the Credit Documents, to the extent the
         obligations of a Guarantor shall be adjudicated to be invalid or
         unenforceable for any reason (including, without limitation, because of
         any applicable state or federal law relating to fraudulent conveyances
         or transfers) then the obligations of each Guarantor hereunder shall be
         limited to the maximum amount that is permissible under applicable law
         (whether federal or state and including, without limitation, the
         Bankruptcy Code).

         25. Rights of Required Lenders. All rights of the Agent hereunder, if
not exercised by the Agent, may be exercised by the Required Lenders.

                             Consent to Second Lien

         2.1 GE hereby consents to the granting by the Borrower and the
Guarantors of a second priority security interest in the GE Collateral and
agrees that the granting thereof shall not constitute a default under the GE
Agreements or any other documents executed in connection with the transactions
evidenced by the GE Agreements.

                                    SECTION 3

                             Subordination of Liens

         3.1 Notwithstanding anything to the contrary contained in the Credit
Documents, the Agent hereby (a) acknowledges that the GE Collateral is (and/or
will be from time to time) subject to Liens on and security interests in favor
of each of the Agent (arising under the Credit Documents) and GE (arising under
the GE Agreements), (b) hereby expressly subordinates its interest in and to any
present or future GE Collateral to the prior interests of GE arising under the
GE Agreements, and (c) agrees that any Lien or security interest of GE is and
shall remain prior to any Lien or security interest in or to any present or
future GE Collateral and that the Agent's Lien and security interest in and to
any present or future GE Collateral shall at all times remain subordinated to
any such Lien or security interest of GE in the GE Collateral.

         3.2 Until such time as all GE Obligations shall have been paid
irrevocably in full and the GE Agreements shall have been terminated, the Agent
agrees that it will not commence or continue any foreclosure or liquidation
proceedings or remedies in respect of any of the GE Collateral. In the event
that any of the GE Collateral, or any collections or other proceeds thereof,
shall be received by the Agent at any time for any reason, such GE Collateral
and/or proceeds shall be held in trust for the benefit of, and promptly remitted
to GE.

         3.3 Notwithstanding anything to the contrary contained in this
Agreement, the Agent may file UCC financing statements and continuation
statements to preserve its Liens and security interests in the GE Collateral and
may file such claims and proofs of claim and take such other action as may be
necessary to enforce its claim in any bankruptcy, insolvency, reorganization,
liquidation or similar proceeding. The Agent agrees not to initiate, prosecute,
encourage, or cooperate with any other Person to initiate or prosecute any
claim, action or other proceeding (a) challenging the enforceability of GE's
claim, (b) challenging the perfection or enforceability of any Liens or security
interests in GE Collateral securing any GE Obligations or (c) asserting any
claims which the Borrower or any Guarantor may hold with respect to GE or the GE
Obligations.

         3.4 No right of GE to enforce subordination as herein provided shall at
any time in any way be prejudiced or impaired by any act or failure to act by
GE, or by any noncompliance by the Borrower or any Guarantor with the terms and
provisions and covenants herein, regardless of any knowledge thereof such holder
may have or otherwise be charged with.

                                    SECTION 4

                    Modification of GE Obligations; Reliance

        4.1 The Agent consents that, without the necessity of any reservation of
rights against the Agent, and without notice to or further assent by the Agent,
the GE Obligations and any document or instrument evidencing or 





governing the terms of any GE Obligations or any collateral security documents
or guaranties or documents relating to the GE Obligations may be amended,
modified, supplemented or terminated, in whole or in part, as GE may deem
advisable from time to time, and any GE Collateral at any time securing payment
of any of the GE Obligations may be sold, exchanged, waived, surrendered or
released, in each case all without notice to or further assent by the Agent,
which will remain bound under this Agreement, and all without impairing,
abridging, releasing or affecting the subordination provided for herein,
notwithstanding any such renewal, extension, modification, acceleration,
compromise, amendment, supplement, termination, sale, exchange, waiver,
surrender or release. The Agent waives any and all notice of the creation,
modification, renewal, extension or accrual of any of the GE Obligations.

                                    SECTION 5

                                  Miscellaneous

         5.1 No failure to exercise, and no delay in exercising on the part of
GE, from time to time, any rights, power and privileges under the GE
Obligations, or any right, power or privilege under this Agreement shall operate
as a waiver thereof, nor shall any single or partial exercise of any right,
power or privilege under this Agreement preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies provided in this Agreement and in any agreement relating to any of the
GE Obligations and all other agreements, instruments and documents referred to
in any of the foregoing are cumulative and shall not be exclusive of any rights

in part only by registration of such transfer on the Register maintained by or

         attached hereto.

                  (iv) The patents and trademarks listed on Schedule 4 attached
         hereto constitute all of the registrations and applications for the
         patents and trademarks owned by the Subsidiary.

         3. The Subsidiary hereby acknowledges, agrees and confirms that, by its
execution of this Agreement, the Subsidiary will be deemed to be a party to the
Pledge Agreement, and shall have all the obligations of a "Pledgor" thereunder
as if it had executed the Pledge Agreement. The Subsidiary hereby ratifies, as
of the date hereof, and agrees to be bound by, all the terms, provisions and
conditions contained in the Pledge Agreement. Without limiting the generality of
the foregoing terms of this paragraph 3, the Subsidiary hereby pledges and



                                      -1-
