         subject to the terms and conditions hereof, each Lender severally
         agrees to make revolving credit loans each a "Revolving Loan" and
         collectively (the "Revolving Loans") to each of the Borrowers from
         time to time in the amount of such Lender's Revolving Commitment
         Percentage of such requested Revolving Loans for the purposes

         outstanding at any time shall not exceed the Aggregate Revolving
         Committed Amount and (ii) with regard to each Lender individually,
         such Lender's Revolving Commitment Percentage of the sum of the

                           (i) Notice of Borrowing. By no later than 10:00 A.M.
                  (San Francisco time) on the Business Day of the requested
                  borrowing in the case of Base Rate Loans, and on the third

                  Notice of Borrowing shall fail to specify (I) an applicable
                  Interest Period in the case of a Eurodollar Loan, then such

                  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
                  Lender promptly upon receipt of each Notice of Borrowing

                  on the books of such office with the aggregate of the amounts
                  made available to the Agent by the Lenders and in like funds

         Bank. The Fronting Bank will provide to the Agent at least monthly,
         and more frequently upon request, a detailed summary report on its
         Letters of Credit and the activity thereon, in form and substance
         acceptable to the Agent. In addition, the Fronting Bank will provide
         to the Agent for dissemination to the Lenders at least quarterly, and
         more frequently upon request, a detailed summary report on its Letters
         of Credit and the activity thereon, including, among other things, the
         beneficiary, the face amount, and the expiry date. The Fronting Bank
         will provide copies of the Letters of Credit to the Agent and the
         Lenders promptly upon request.

                  (c) Participation. Each Lender, with respect to Letters of
         Credit issued on or after the Closing Date, upon issuance of a Letter
         of Credit, shall be deemed to have purchased without recourse a
         participation from the Fronting Bank in such Letter of Credit and the
         obligations arising thereunder, in each case in an amount equal to its
         Revolving Commitment Percentage of the obligations under such Letter
         of Credit and shall absolutely, unconditionally and irrevocably
         assume, as primary obligor and not as surety, and be obligated to pay
         to the Fronting Bank therefor 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 in any
         Letter of Credit, to the extent that the Fronting Bank has not been
         reimbursed as required hereunder or under any such Letter of Credit,
         each such Lender shall pay to the Agent for further credit to the
         Fronting Bank its Revolving Commitment Percentage of such unreimbursed
         drawing in same day funds on the day of notification by the Agent of
         an unreimbursed drawing pursuant to the provisions of subsection (d)
         hereof. The obligation of each Lender to so reimburse the Fronting
         Bank 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 applicable Borrower to
         reimburse the Fronting Bank 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 Fronting Bank will promptly notify the Borrower
         that was the applicant for such Letter of


                                      27
<PAGE>   33


         Credit. Unless such Borrower shall immediately notify the Fronting
         Bank that it intends to otherwise reimburse the Fronting Bank for such
         drawing, such 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) hereof on the related Letter of Credit, the proceeds
         of which will be used to satisfy the related reimbursement
         obligations. Each Borrower that is the applicant under a Letter of
         Credit promises to reimburse the Fronting Bank 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 such
         Borrower shall fail to reimburse the Fronting Bank as provided
         hereinabove, the unreimbursed amount of such drawing shall bear
         interest at a per annum rate equal to the Base Rate plus two percent
         (2%). Such Borrower's reimbursement obligations hereunder shall be
         absolute and unconditional under all circumstances irrespective of any
         rights of setoff, counterclaim or defense to payment such Borrower may
         claim or have against the Fronting Bank, 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 such
         Borrower to receive consideration or the legality, validity,
         regularity or unenforceability of the Letter of Credit. The Fronting
         Bank will promptly notify the Agent who will promptly notify the
         Lenders of the amount of any unreimbursed drawing and each Lender
         shall promptly pay to the Agent for the account of the Fronting Bank
         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 Agent if such notice is received at or before 12:30 P.M. (New York
         time) otherwise such payment shall be made at or before 9:00 A.M. (New
         York time) on the Business Day next succeeding the day such notice is
         received. If such Lender does not pay such amount to the Agent for the
         account of the Fronting Bank in full upon such request, such Lender
         shall, on demand, pay to the Agent for the account of the Fronting
         Bank interest on the unpaid amount during the period from the date of
         such drawing until such Lender pays such amount to the Agent for the
         account of the Fronting Bank 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 Agent
         for the account of the Fronting Bank, and the right of the Fronting
         Bank 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 any 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
         Agent for the account of the Fronting Bank, such Lender shall,
         automatically and without any further action on the part of the
         Fronting Bank or such Lender, acquire a participation in an amount
         equal to such payment (excluding the portion of such payment
         constituting interest owing to the Fronting Bank) 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 such Borrower with respect thereto.

                  (e) Repayment with Revolving Loans. On any day on which any
         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


                                      28
<PAGE>   34


         a Revolving Loan has been requested or deemed requested by such
         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 such Borrower has complied
         with the procedures of Section 2.1(b)(i) with respect thereto) shall
         be immediately made to such 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 before giving effect to any termination of the
         Commitments pursuant to Section 9.2) and the proceeds thereof shall be
         paid directly to the Fronting Bank 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 5.2 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 a Borrower), 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 such Borrower on or after such date and prior to such
         purchase) from the Fronting Bank such participation 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 in the event such payment is not made on
         the day of drawing, such Lender shall pay in addition to the Fronting
         Bank interest on the amount of its unfunded Participation Interest at
         a rate equal to, if paid within two (2) Business Days of the date of
         drawing, the Federal Funds Rate, and thereafter at the Base Rate.

                  (f) Designation of 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 Subsidiary or Alliance of a Borrower, provided
         that notwithstanding such statement, in such circumstances the
         Borrower requesting such Letter of Credit shall be the actual account
         party for all purposes of this Credit Agreement for such Letter of
         Credit and such statement shall not affect such 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.


                                      29
<PAGE>   35


                  (h) Uniform Customs and Practices. The Fronting Bank 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 Fronting Bank's Duties.

                           (i) In addition to its other obligations under this
                  Section 2.2, each Borrower that is an applicant with respect
                  to a Letter of Credit hereby agrees to protect, indemnify,
                  pay and save the Fronting Bank harmless from and against any
                  and all claims, demands, liabilities, damages, losses, costs,
                  charges and expenses (including reasonable attorneys' fees
                  actually incurred) that the Fronting Bank may incur or be
                  subject to as a consequence, direct or indirect, of (A) the
                  issuance of any Letter of Credit upon the application of such
                  Borrower or (B) the failure of the Fronting Bank to honor a
                  drawing under a Letter of Credit issued upon the application
                  of such Borrower 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 that is the applicant
                  for a Letter of Credit and the Fronting Bank for such Letter
                  of Credit, such Borrower shall assume all risks of the acts,
                  omissions or misuse of any such Letter of Credit by the
                  beneficiary thereof. The Fronting Bank shall not be
                  responsible: (A) for the form, 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 the Fronting Bank, including,
                  without limitation, any Government Acts. None of the above
                  shall affect, impair, or prevent the vesting of the Fronting
                  Bank'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 the Fronting Bank, under or in
                  connection with any Letter of Credit or the related
                  certificates, if taken or omitted in good faith, shall not
                  put such Fronting Bank under any resulting liability to such
                  Borrower. It is the intention of the parties that this Credit
                  Agreement shall be construed and applied to protect and
                  indemnify the Fronting Bank against any and all risks
                  involved in the issuance of the Letters of Credit, all of
                  which risks are hereby assumed by the Borrowers, including,
                  without limitation, any and all


                                      30
<PAGE>   36


                  Government Acts. The Fronting Bank shall not, in any way, be
                  liable for any failure by the Fronting Bank 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 the
                  Fronting Bank.

                           (iv) Nothing in this Section 2.2(i) is intended to
                  limit the reimbursement obligations of the Borrowers
                  contained in subsection (d) above. The obligations of the
                  Borrowers under this Section 2.2(i) 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 Fronting Bank
                  to enforce any right, power or benefit under this Credit
                  Agreement.

                           (v) Notwithstanding anything to the contrary
                  contained in this subsection (i), the Borrowers shall have no
                  obligation to indemnify the Fronting Bank in respect of any
                  liability incurred by the Fronting Bank (A) to the extent
                  arising out of the gross negligence or willful misconduct of
                  the Fronting Bank, as determined by a court of competent
                  jurisdiction, or (B) caused by the Fronting Bank'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 Fronting Bank. It is expressly
         understood and agreed that the obligations of the Fronting Bank
         hereunder to the Lenders are only those expressly set forth in this
         Credit Agreement and that the Fronting Bank shall be entitled to
         assume that the conditions precedent set forth in Section 5.2 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 Fronting Bank
         any amounts made available by such Lender to the Fronting Bank
         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 Fronting Bank.

                  (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.

         2.3 SEVERAL OBLIGATIONS OF THE BORROWERS.

         The obligations of the Borrowers, as Borrowers, are several and not
joint obligations of each of the Borrowers.


                                      31

                                   SECTION 3
                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES

         3.1 DEFAULT RATE.

         Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per annum rate two percent (2%)
greater than the rate which would otherwise be applicable (or if no rate is
applicable, whether in respect of interest, fees or other amounts, then two
percent (2%) greater than the Base Rate).

         3.2 EXTENSION AND CONVERSION.

         Subject to the terms of Section 5.2, the Borrowers 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 (a) 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, (b) 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 and
the conditions set forth in subsections (b) and (c) of Section 5.2 have been
satisfied, (c) 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, Section
2.1(b)(ii), and (d) 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 (1) month. Each such extension or
conversion shall be effected by one or more of the Borrowers by giving a Notice
of Extension/Conversion, in the form of Exhibit 3.2, to the Agent prior to
10:00 A.M. (San Francisco time) on the Business Day of, in the case of the
conversion of a Eurodollar Loan into a Base Rate Loan, and on the third (3rd)
Business Day prior to, in the case of the extension of a Eurodollar Loan as, or
conversion of a Base Rate Loan into, a Eurodollar Loan, 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
applicable Borrower of the matters specified in subsections (b) through (c) of
Section 5.2. In the event a 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.

         3.3 PREPAYMENTS.

                  (a) Voluntary Prepayments. Loans may be repaid in whole or in
         part without premium or penalty; provided that (i) Eurodollar Loans
         may not be prepaid other than at the end of the Interest Period
         applicable thereto and only then on three (3) Business Days' prior
         written notice to the Agent, (ii) any prepayment of Eurodollar Loans
         will be


                                      32
<PAGE>   38


         subject to Section 3.11, (iii) Base Rate Loans may be prepaid by the
         Borrowers by giving notice to the Agent prior to 10:00 A.M. (San
         Francisco time) on the day of repayment of the requested prepayment,
         and (iv) each such partial prepayment shall be in a minimum principal
         amount of $5,000,000, in the case of Eurodollar Loans, and $1,000,000,
         in the case of Base Rate Loans, and in integral multiples of
         $1,000,000 in excess thereof. Any such voluntary prepayments shall be
         applied in the manner directed by the applicable Borrower in the
         notice of prepayment, or if any notice of prepayment fails to specify
         the application thereof, such prepayment shall be applied first to
         Base Rate Loans and then to Eurodollar Loans in direct order of their
         Interest Period maturities.

                  (b) Mandatory Prepayments.

                           (i) If at any time, the aggregate principal amount
                  of Obligations shall exceed the Aggregate Revolving Committed
                  Amount as reduced from time to time, the Borrowers shall
                  immediately make a principal payment to the Lenders for
                  application to the Obligations in the manner and in an amount
                  necessary to be in compliance with Section 2.1. Any such
                  mandatory prepayment shall be applied first to Base Rate
                  Loans and then to Eurodollar Loans in the direct order of
                  their Interest Period maturities.

                           (ii) Asset Dispositions. The Revolving Loans
                  outstanding hereunder shall be prepaid in an amount equal to
                  one hundred percent (100%) of the Net Proceeds received from
                  Asset Dispositions to the extent that (A) such Net Proceeds
                  are not reinvested in similar property or assets within one
                  hundred eighty (180) days of the date of sale, lease,
                  disposition, casualty, theft or loss which gave rise to the
                  Asset Disposition, and (B) the aggregate amount of such Net
                  Proceeds not reinvested in accordance with the foregoing
                  subsection (i) shall exceed $1,000,000 in any fiscal year.

         3.4 VOLUNTARY REDUCTIONS IN REVOLVING COMMITMENTS.

                  The Borrowers may from time to time permanently reduce the
         aggregate amount of the Revolving Commitments in whole or in part
         without premium or penalty except as provided in Section 3.11 upon
         three (3) Business Days' prior written notice to the Agent (who shall
         promptly notify each Lender), provided that (i) after giving effect to
         any voluntary reduction the aggregate amount of Obligations shall not
         exceed the Aggregate Revolving Committed Amount, as reduced, and (ii)
         partial reductions shall be minimum principal amount of $5,000,000,
         and in integral multiples of $1,000,000 in excess thereof.

         3.5 FEES.

                  (a) Unused Fee. In consideration of the Revolving Commitments
         hereunder, NIS agrees to pay to the Agent, for the ratable benefit of
         the Lenders, an unused fee (the "Unused Fee") equal to the Applicable
         Percentage for Unused Fees then in effect (calculated on the basis of
         actual number of days elapsed in a year of three hundred sixty (360)
         days) on the average daily unused portion of the Aggregate Revolving
         Committed Amount for the applicable period. The Unused Fee shall be
         payable quarterly in arrears


                                      33
<PAGE>   39


         on the fifteenth (15th) day following the last day of each calendar
         quarter (as well as on the Termination Date) for the immediately
         preceding quarter (or portion thereof) beginning with the first such
         date to occur after the Closing Date.

                  (b) Letter of Credit Fees.

                           (i) Letter of Credit Issuance Fee. In consideration
                  of the issuance of Letters of Credit hereunder, each Borrower
                  promises to pay to the Agent, for the account of each Lender,
                  a fee (the "Letter of Credit Fee") on such Lender's Revolving
                  Commitment Percentage of the average daily maximum amount
                  available to be drawn under each such standby Letter of
                  Credit issued for the account of such Borrower computed at a
                  per annum rate for each day from the date of issuance to the
                  date of expiration equal to the Applicable Percentage for
                  Letter of Credit Fees then in effect. The Letter of Credit
                  Fee will be payable quarterly in arrears on the last Business
                  Day of each March, June, September and December (as well as
                  on the Termination Date) for the immediately preceding
                  quarter (or a portion thereof).

                           (ii) Fronting Bank Fee. In addition to the Letter of
                  Credit Fee payable pursuant to clause (i) above, each
                  Borrower promises to pay to the Fronting Bank for its own
                  account without sharing by the other Lenders (A) letter of
                  credit fronting and negotiation fees of one-eighth percent
                  (1/8%) per annum on the average daily maximum amount
                  available to be drawn under outstanding Letters of Credit
                  issued for the account of such Borrower payable quarterly in
                  arrears with the Letter of Credit Fee, and (B) customary
                  charges from time to time of the Fronting Bank with respect
                  to the issuance, amendment, transfer, administration,
                  cancellation and conversion of, and drawings under, such
                  Letters of Credit (collectively, the "Fronting Bank Fees").

                  (c) Administrative Fees. NIS agrees to pay to the Agent, for
         its own account, an annual administrative fee and such other fees, if
         any, referred to in the Agent's Fee Letter.

         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 Borrowers, the
Borrowers shall be obligated to pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction. Each determination
by any such Lender of amounts


                                      34
<PAGE>   40


owing under this Section shall, absent manifest error, be conclusive and binding
on the parties hereto.

         3.7 INABILITY TO DETERMINE INTEREST RATE.

         If prior to the first (1st) day of any Interest Period, the Agent
shall have determined (which determination shall be conclusive and binding upon
the Borrowers) 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, the Agent shall give telecopy or telephonic notice
thereof to the Borrowers and the Lenders as soon as practicable thereafter. If
such notice is given (a) any Eurodollar Loans requested to be made on the first
(1st) day of such Interest Period shall be made as Base Rate Loans and (b) any
Loans that were to have been converted on the first day of such Interest Period
to or continued as Eurodollar Loans shall be converted to or continued as Base
Rate Loans. Until such notice has been withdrawn by the Agent, no further
Eurodollar Loans shall be made or continued as such, nor shall the Borrowers
have the right to convert Base Rate Loans to Eurodollar Loans.

         3.8 ILLEGALITY.

         Notwithstanding any other provision herein, if the adoption of or any
change in any Requirement of Law or in the interpretation or application
thereof occurring after the Closing Date shall make it unlawful for any Lender
to make or maintain Eurodollar Loans as contemplated by this Credit Agreement,
(a) such Lender shall promptly give written notice of such circumstances to the
Borrowers and the Agent (which notice shall be withdrawn whenever such
circumstances no longer exist), (b) the commitment of such Lender hereunder to
make Eurodollar Loans, continue Eurodollar Loans as such and convert a Base
Rate Loan to Eurodollar Loans shall forthwith be canceled and, until such time
as it shall no longer be unlawful for such Lender to make or maintain
Eurodollar Loans, such Lender shall then have a commitment only to make a Base
Rate Loan when a Eurodollar Loan is requested and (c) such Lender's Loans then
outstanding as Eurodollar Loans, if any, shall be converted automatically to
Base Rate Loans on the respective last days of the then current Interest
Periods with respect to such Loans or within such earlier period as required by
law. If any such conversion of a Eurodollar Loan occurs on a day which is not
the last day of the then current Interest Period with respect thereto, the
Borrowers shall pay to such Lender such amounts, if any, as may be required
pursuant to Section 3.11.

         3.9 REQUIREMENTS OF LAW.

         If, after the date hereof, the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof applicable
to any Lender, or compliance by any Lender with any request or directive
(whether or not having the force of law) from any central bank or other
Governmental Authority, in each case made subsequent to the Closing Date (or,
if later, the date on which such Lender becomes a Lender):

                  (a) shall subject such Lender to any tax of any kind
         whatsoever with respect to any Letter of Credit, any Eurodollar Loans
         made by it or its obligation to make Eurodollar Loans, or change the
         basis of taxation of payments to such Lender in respect thereof
         (except for (i) Non-Excluded Taxes covered by Section 3.10 (including
         Non-Excluded Taxes


                                      35
<PAGE>   41


         imposed solely by reason of any failure of such Lender to comply with
         its obligations under Section 3.10(b)) and (ii) changes in taxes
         measured by or imposed upon the net income, or franchise tax (imposed
         in lieu of such net income tax), of such Lender or its applicable
         lending office, branch, or any affiliate thereof));

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

                  (c) shall impose on such Lender any other condition
         (excluding any tax of any kind whatsoever);

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting
into, continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, upon notice to the Borrowers from such Lender,
through the Agent, in accordance herewith, the Borrowers shall be obligated to
promptly pay such Lender, upon its demand, any additional amounts necessary to
compensate such Lender for such increased cost or reduced amount receivable,
provided that, in any such case, the Borrowers may elect to convert the
Eurodollar Loans made by such Lender hereunder to Base Rate Loans by giving the
Agent at least one (1) Business Day's notice of such election, in which case
the Borrowers shall promptly pay to such Lender, upon demand, without
duplication, such amounts, if any, as may be required pursuant to Section 3.11.
If any Lender becomes entitled to claim any additional amounts pursuant to this
subsection, it shall provide prompt notice thereof to the Borrowers, through
the Agent, certifying (x) that one of the events described in this paragraph
(a) has occurred and describing in reasonable detail the nature of such event,
(y) as to the increased cost or reduced amount resulting from such event and
(z) as to the additional amount demanded by such Lender and a reasonably
detailed explanation of the calculation thereof. Such a certificate as to any
additional amounts payable pursuant to this subsection submitted by such
Lender, through the Agent, to the Borrowers shall be conclusive and binding on
the parties hereto in the absence of manifest error. This covenant shall
survive the termination of this Credit Agreement and the payment of the Loans
and all other amounts payable hereunder.

         3.10 TAXES.

                  (a) Except as provided below in this subsection, all payments
         made by the Borrowers under this Credit Agreement and any Notes shall
         be made free and clear of, and without deduction or withholding for or
         on account of, any present or future income, stamp or other taxes,
         levies, imposts, duties, charges, fees, deductions or withholdings,
         now or hereafter imposed, levied, collected, withheld or assessed by
         any court, or governmental body, agency or other official, excluding
         taxes measured by or imposed upon the net income of any Lender or its
         applicable lending office, or any branch or affiliate thereof, and all
         franchise taxes, branch taxes, taxes on doing business or taxes on the
         capital or net worth of any Lender or its applicable lending office,
         or any branch or affiliate thereof, in each case imposed in lieu of
         net income taxes, imposed: (i) by the jurisdiction under the laws of
         which


                                      36
<PAGE>   42


         such Lender, applicable lending office, branch or affiliate is
         organized or is located, or in which its principal executive office is
         located, or any nation within which such jurisdiction is located or
         any political subdivision thereof; or (ii) by reason of any connection
         between the jurisdiction imposing such tax and such Lender, applicable
         lending office, branch or affiliate other than a connection arising
         solely from such Lender having executed, delivered or performed its
         obligations, or received payment under or enforced, this Credit
         Agreement or any Notes (collectively, "Excluded Taxes"). If any taxes,
         levies, imposts, duties, charges, fees, deductions or withholdings
         other than Excluded Taxes (collectively "Non-Excluded Taxes") are
         required to be withheld from any amounts payable to the Agent or any
         Lender hereunder or under any Notes, (A) the amounts so payable to the
         Agent or such Lender shall be increased to the extent necessary to
         yield to the Agent or such Lender (after payment of all Non-Excluded
         Taxes) interest or any such other amounts payable hereunder at the
         rates or in the amounts specified in this Credit Agreement and any
         Notes, provided, however, that the Borrowers shall be entitled to
         deduct and withhold any Non-Excluded Taxes and shall not be required
         to increase any such amounts payable to any Lender that is not
         organized under the laws of the United States of America or a state
         thereof if such Lender fails to comply with the requirements of
         paragraph (b) of this subsection whenever any Non-Excluded Taxes are
         payable by the Borrowers, and (B) as promptly as possible thereafter
         the Borrowers shall send to the Agent for its own account or for the
         account of such Lender, as the case may be, a certified copy of an
         original official receipt received by one or more of the Borrowers
         showing payment thereof. If the Borrowers fail to pay any Non-Excluded
         Taxes when due to the appropriate taxing authority or fails to remit
         to the Agent the required receipts or other required documentary
         evidence, the Borrowers shall indemnify the Agent and the Lenders for
         any incremental taxes, interest or penalties that may become payable
         by the Agent or any Lender as a result of any such failure. The
         agreements in this subsection shall survive the termination of this
         Credit Agreement and the payment of the Loans and all other amounts
         payable hereunder.

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

                           (X)(i) on or before the date of any payment by the
                  Borrowers under this Credit Agreement or Notes to such
                  Lender, deliver to the Borrowers and the Agent (A) two (2)
                  duly completed copies of United States Internal Revenue
                  Service Form 1001 or 4224, or successor applicable form, as
                  the case may be, certifying that it is entitled to receive
                  payments under this Credit Agreement and any Notes without
                  deduction or withholding of any United States federal income
                  taxes and (B) an Internal Revenue Service Form W-8 or W-9, or
                  successor applicable form, as the case may be, certifying
                  that it is entitled to an exemption from United States backup
                  withholding tax;

                                    (ii) deliver to the Borrowers and the Agent
                           two (2) further copies of any such form or
                           certification on or before the date that any such
                           form or certification expires or becomes obsolete
                           and after the occurrence of any event requiring a
                           change in the most recent form previously delivered
                           by it to the Borrowers; and


                                      37
<PAGE>   43


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

                           (Y) in the case of any such Lender that is not a
                  "bank" within the meaning of Section 881(c)(3)(A) of the
                  Internal Revenue Code, (i) represent to the Borrowers (for
                  the benefit of the Borrowers and the Agent) that it is not a
                  bank within the meaning of Section 881(c)(3)(A) of the
                  Internal Revenue Code, (ii) agree to furnish to the Borrowers
                  on or before the date of any payment by the Borrowers, with a
                  copy to the Agent two (2) accurate and complete original
                  signed copies of Internal Revenue Service Form W-8, or
                  successor applicable form certifying to such Lender's legal
                  entitlement at the date of such certificate to an exemption
                  from U.S. withholding tax under the provisions of Section
                  881(c) of the Internal Revenue Code with respect to payments
                  to be made under this Credit Agreement and any Notes (and to
                  deliver to the Borrowers and the Agent two (2) further copies
                  of such form on or before the date it expires or becomes
                  obsolete and after the occurrence of any event requiring a
                  change in the most recently provided form and, if necessary,
                  obtain any extensions of time reasonably requested by the
                  Borrowers or the Agent for filing and completing such forms),
                  and (iii) agree, to the extent legally entitled to do so,
                  upon reasonable request by the Borrowers, to provide to the
                  Borrowers (for the benefit of the Borrowers and the Agent)
                  such other forms as may be reasonably required in order to
                  establish the legal entitlement of such Lender to an
                  exemption from withholding with respect to payments under
                  this Credit Agreement and any Notes;

         unless in any such case any change in treaty, law or regulation has
         occurred after the date such Person becomes a Lender hereunder which
         renders all such forms inapplicable or which would prevent such Lender
         from duly completing and delivering any such form with respect to it
         and such Lender so advises the Borrowers and the Agent. Each Person
         that shall become a Lender or a participant of a Lender pursuant to
         Section 11.3 shall, upon the effectiveness of the related transfer, be
         required to provide all of the forms, certifications and statements
         required pursuant to this subsection, provided that in the case of a
         participant of a Lender the obligations of such participant of a
         Lender pursuant to this subsection (b) shall be determined as if the
         participant of a Lender were a Lender except that such participant of
         a Lender shall furnish all such required forms, certifications and
         statements to the Lender from which the related participation shall
         have been purchased.

         3.11 INDEMNITY.

         The Borrowers promise to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur (other
than through such Lender's gross negligence or willful misconduct) as a
consequence of (a) any payment, prepayment, or conversion of a Eurodollar Loan
for any reason including, without limitation, in connection with any assignment
by Bank of America pursuant to Section 11.3(b) as part of the primary
syndication of the Loans during the 180-day period immediately following the
Closing Date, (b) default by any of the Borrowers in making a borrowing of,
conversion into or continuation of Eurodollar Loans after notice has been given
requesting the same in accordance with the provisions of this Credit


                                      38
<PAGE>   44


Agreement, (c) default by the Borrowers in making any prepayment of a
Eurodollar Loan after notice thereof has been given in accordance with the
provisions of this Credit Agreement or (d) the making of a prepayment of
Eurodollar Loans on a day which is not the last day of an Interest Period with
respect thereto. With respect to Eurodollar Loans, such indemnification may
include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the amount so prepaid, or not so borrowed,
converted or continued, for the period from the date of such prepayment or of
such failure to borrow, convert or continue to the last day of 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 over (ii) the amount of interest (as reasonably determined by such
Lender) which would have accrued to such Lender on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank
Eurodollar market. The covenants of the Borrowers set forth in this Section
3.11 shall survive the termination of this Credit Agreement and the payment of
the Loans and all other amounts payable hereunder.

         3.12 PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

                  (a) Loans. Each Extension of Credit in respect of the
         Revolving Loans and LOC Obligations and payments of principal,
         interest and fees (including the Unused Fee and Letter of Credit Fee)
         on or in respect thereof and each reduction in Commitments, relating
         thereto, and each conversion or extension of such Loans and
         Obligations, shall be allocated pro rata among the Lenders in
         accordance with the respective principal amounts of their outstanding
         Revolving Loans and Participation Interests.

                  (b) Advances. Unless the Agent shall have been notified in
         writing by any Lender prior to a borrowing that such Lender will not
         make the amount that would constitute its ratable share of such
         borrowing available to the Agent, the Agent may assume that such
         Lender is making such amount available to the Agent, and the Agent
         may, in reliance upon such assumption, make available to one or more
         of the Borrowers a corresponding amount. If such amount is not made
         available to the Agent by such Lender within the time period specified
         therefor hereunder, such Lender shall pay to the Agent, on demand,
         such amount with interest thereon at a rate equal to the Federal Funds
         Rate for the period until such Lender makes such amount immediately
         available to the Agent. A certificate of the Agent submitted to any
         Lender with respect to any amounts owing under this subsection shall
         be conclusive in the absence of manifest error.

         3.13 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


                                      39
<PAGE>   45


shall promptly purchase from the other Lenders a participation in such Loans,
LOC Obligations and other obligations in such amounts, and make 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 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 Borrowers
agree that any Lender so purchasing such a participation 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 as fully as
if such Lender were a holder of such Loan, LOC Obligations or other obligation
in the amount of such participation. 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 3.13 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 3.13 to share in the benefits of any
recovery on such secured claim.

         3.14 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 offset, deduction, counterclaim
         or withholding of any kind, at the Agent's office specified in Section
         11.1 not later than 12:30 P.M. (San Francisco 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 any of the
         Borrowers maintained with the Agent (with notice to the Borrowers).
         The Borrowers (or any of them) shall, at the time a payment is made
         under this Credit Agreement, specify to the Agent the Loans, LOC
         Obligations, Fees, interest or other amounts payable by the Borrowers
         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 Borrowers
         hereunder, subject to the terms of Section 3.12(a)). The Agent will
         distribute such payments to such Lenders, if such payment is received
         on or before 12:30 P.M. (San Francisco 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


                                      40
<PAGE>   46


         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 three
         hundred sixty (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 three hundred sixty-five (365) or three hundred sixty-six
         (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 Obligations or any other amounts outstanding
         under any of the Credit Documents 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 attorney's fees actually incurred) of the Agent in
                  connection with enforcing the rights of the Lenders under the
                  Credit Documents;

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

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

                           FOURTH, to the payment of all accrued interest and
                  fees on or in respect of the Obligations;

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

                           SIXTH, to all other 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; and (ii) each of the Lenders shall
         receive an amount equal to its pro rata share (based on the proportion
         that the then outstanding Obligations held by such Lender bears to the
         aggregate then outstanding Obligations) of amounts available to be
         applied pursuant to clauses "THIRD",


                                      41
<PAGE>   47


         "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 Fronting
         Bank for any drawings under such Letters of Credit and (B) then,
         following the expiration or earlier cancellation 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
         3.14(b).

         3.15 EVIDENCE OF DEBT.

                  (a) Each Lender shall maintain an account or accounts
         evidencing each Loan made by such Lender to the Borrowers 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, and to provide a copy of such account
         or accounts to the Borrowers upon request.

                  (b) The Agent shall maintain the Register pursuant to Section
         11.3(c) hereof, 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 a 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 3.15
         (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 Borrowers 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 Borrowers to
         repay the Loans made by such Lender in accordance with the terms
         hereof.

         3.16 REPLACEMENT OF LENDERS.

                  Upon the occurrence of (i) (x) an event that requires the
         Borrowers to pay additional amounts to any Lender or any Governmental
         Authority for the account of any Lender pursuant to Section 3.6, 3.9
         or 3.10 and (y) a demand by a Lender for such amounts from the
         Borrowers, (ii) a default by a Lender in its obligation to fund Loans
         hereunder or (iii) a grant or other transfer of a participation by any
         Lender of its interests and obligations hereunder pursuant to Section
         11.3(d) to any bank or financial institution which (x) is engaged in a
         CCTP Business, (y) could reasonably be considered a competitor of a
         Borrower and (z) is objectionable to the Borrowers in the exercise of
         their reasonable judgment, then, in any such case, the Borrowers may,
         at their sole expense and effort, upon notice to the applicable Lender
          and the Agent, require such Lender to assign and delegate, without
         recourse (in accordance with and subject to the restrictions


                                      42
<PAGE>   48


         contained in Section 11.3), all its interests, rights and obligations
         under this Agreement to an Eligible Assignee that shall assume such
         obligations (which assignee may be another Lender, if a Lender accepts
         such assignment); provided that (a) the Borrowers shall have received
         the prior written consent of the Agent (and, if the LOC Commitment is
         being assigned, the Fronting Bank), which consent shall not
         unreasonably be withheld, (b) such Lender shall have received payment
         of an amount equal to the outstanding principal of its Loans and
         participations in Letters of Credit, accrued interest thereon, accrued
         fees and all other amounts payable to it hereunder, from the assignee
         (to the extent of such outstanding principal and accrued interest and
         fees) or the Borrowers (in the case of all other amounts) and (c) in
         the case of any such assignment resulting from a claim for
         compensation under Section 3.9, such assignment will result in a
         material reduction in such compensation or payments. If a Lender
         defaults, the Borrowers do not waive any of their rights against such
         Lender if the Borrowers cause the defaulting Lender to assign its
         position. The Borrowers agree to pay all reasonable costs and expenses
         incurred by any Lender in connection with any such designation or
         assignment (including any break-funding costs).


                                   SECTION 4
                                    GUARANTY

         4.1 THE GUARANTEE.

         Each of the Guarantors hereby jointly and severally irrevocably
guarantees to each Lender, to each Affiliate of a Lender that enters into a
Hedging Agreement, and to 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, 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 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 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 hereof 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


                                      43
<PAGE>   49


to therein, or any substitution, release 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 any of the Borrowers or any other Guarantor of the Credit Party
Obligations for amounts paid under this Guaranty until such time as the Lenders
(and any Affiliates of Lenders entering into Hedging Agreements) have been paid
in full, all Commitments under the 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;

                  (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 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.

<PAGE>   50


         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.
ss.ss. 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 hereof (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 hereof 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 said Section 4.1.

         4.6 RIGHTS OF CONTRIBUTION.

         The Guarantors hereby agree, as among themselves, that if any
Guarantor shall become an Excess Funding Guarantor (as defined below), each
other Guarantor shall, on demand of such Excess Funding Guarantor (but subject
to the succeeding provisions of this Section 4.6), pay to such Excess Funding
Guarantor an amount equal to such Guarantor's Pro Rata Share (as defined below
and determined, for this purpose, without reference to the properties, assets,
liabilities and debts of such Excess Funding Guarantor) of such Excess Payment
(as defined below). The payment obligation of any Guarantor to any Excess
Funding Guarantor under this Section 4.6 shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Guarantor under the other provisions of this Section 4, and such Excess Funding
Guarantor shall not exercise any right or remedy with respect to such excess
until payment and satisfaction in full of all of such obligations. For purposes
hereof, (a) "Excess Funding Guarantor" shall mean, in respect of


                                      45
<PAGE>   51


any obligations arising under the other provisions of this Section 4
(hereafter, the "Guarantied Obligations"), a Guarantor that has paid an amount
in excess of its Pro Rata Share of the Guarantied Obligations; (b) "Excess
Payment" shall mean, in respect of any Guarantied Obligations, the amount paid
by an Excess Funding Guarantor in excess of its Pro Rata Share of such
Guarantied Obligations; and (c) "Pro Rata Share", for the purposes of this
Section 4.6, shall mean, for any Guarantor, the ratio (expressed as a
percentage) of (i) the amount by which the aggregate present fair saleable
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 saleable
value of all assets and other properties of the Borrowers and all of the
Guarantors exceeds the amount of all of the debts and liabilities (including

precedent on the date of making such Extension of Credit:

                  (a) Notice. The applicable Borrower shall have delivered in

                                   SECTION 6
                         REPRESENTATIONS AND WARRANTIES

         To induce the Lenders to enter into this Credit Agreement and to make
Extensions of Credit herein provided for, each Credit Party hereby represents
and warrants to the Agent and to each Lender that:

         6.1      FINANCIAL CONDITION.

         The financial statements delivered to the Agent pursuant to Section
5.1(b) and Section 7.1 have been prepared in accordance with GAAP consistently
applied throughout the periods covered thereby, are complete and correct in all
material respects and present fairly the financial condition and results from
operations of the entities and for the periods specified, subject in the case
of interim company-prepared statements to normal year-end adjustments.

         6.2      NO CHANGES OR RESTRICTED PAYMENTS.

         Since June 30, 1999, (a) there has been no circumstance, development
or event relating to or affecting the Parent or any of its Subsidiaries which
has had or would be reasonably expected to have a Material Adverse Effect and
(b) except as permitted herein, no Restricted Payments have been made or
declared, or are required to be made or declared pursuant to any agreement (as
to which no conditions to the requirement to make such Restricted Payment
remain to be satisfied) entered into, by the Parent or any of its Subsidiaries.

         6.3      ORGANIZATION; EXISTENCE; COMPLIANCE WITH LAW.

         Each of the Parent and its Subsidiaries (a) is duly organized, validly
existing in good standing under the laws of the jurisdiction of its
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, (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
would not, in the aggregate, have a Material Adverse Effect, and (d) is in
compliance with all Requirements of Law, except to the extent that the failure
to comply therewith would not, in the aggregate, be reasonably expected to have
a Material Adverse Effect.

         6.4      POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS.

         Each Credit Party 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 has taken all necessary corporate action
to authorize the execution, delivery and performance by it of the Credit
Documents to which it is a party. No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the borrowings hereunder or with
the execution, delivery or performance of any Credit Documents by any Credit
Party (other than those which have been obtained) or with the validity or
enforceability of any Credit Document against such Credit Party (except such
filings as are necessary in connection with the perfection of the Liens created
by such Credit


                                      49
<PAGE>   55
Documents). Each Credit Document to which a Credit Party is a party constitutes
a legal, valid and binding obligation of such Credit Party enforceable against
such Credit Party in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by
general equitable principles (whether enforcement is sought by proceedings in
equity or at law).

         6.5      NO LEGAL BAR.

         The execution, delivery and performance of the Credit Documents, the
borrowings hereunder and the use of the Extensions of Credit will not violate
any Requirement of Law or any Contractual Obligation of any Credit Party or any
of its Subsidiaries (except those as to which waivers or consents have been
obtained), and will not result in, or require, the creation or imposition of
any Lien on any of their respective properties or revenues pursuant to any
Requirement of Law or Contractual Obligation (other than the Liens arising
under or contemplated in connection with the Credit Documents). None of the
Credit Parties nor any of their Subsidiaries are in default under or with
respect to any of their Contractual Obligations in any respect which would
reasonably be expected to have a Material Adverse Effect.

         6.6      NO MATERIAL LITIGATION.

         No claim, litigation, investigation or proceeding of or before any
arbitrator or Governmental Authority is pending or, to the best knowledge of
any Credit Party, threatened by or against, the Parent or any of its
Subsidiaries or against any of their respective properties or revenues which
(a) relate specifically to the Credit Documents or any of the transactions
contemplated hereby or thereby, or (b) if adversely determined, would
reasonably be expected to have a Material Adverse Effect. Set forth on Schedule
6.6 is a summary that, as of the Closing Date, describes all material claims,
litigation, investigations and proceedings pending or, to the best knowledge of
any Credit Party, threatened by or against the Parent or any of its
Subsidiaries or against any of their respective properties or revenues, and
none of such actions, individually or in the aggregate, is reasonably expected
to have a Material Adverse Effect.

         6.7      NO DEFAULT.

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

         6.8      OWNERSHIP OF PROPERTY; LIENS.

         Each of the Parent and its Subsidiaries has good record and marketable
title in fee simple to, or a valid leasehold interest in, all its material real
property, and good title to, or a valid leasehold interest in, all its other
material property, and none of such property is subject to any Lien, except for
Permitted Liens.

         6.9      INTELLECTUAL PROPERTY.

         Each of the Parent and its Subsidiaries owns, or has the legal right
to use, all United States trademarks, tradenames, copyrights, patents,
technology, know-how and processes, if any, necessary for each of them to
conduct its business as currently conducted (the "Intellectual


                                      50
<PAGE>   56
Property") except for those the failure to own or have such legal right to use
would not be reasonably expected to have a Material Adverse Effect. No claim
has been asserted and is pending by any Person challenging or questioning the
use of any such Intellectual Property or the validity or effectiveness of any
such Intellectual Property, nor does any Credit Party know of any such claim,
and the use of such Intellectual Property by the Parent or any of its
Subsidiaries does not infringe on the rights of any Person, except for such
claims and infringements that in the aggregate, would not be reasonably
expected to have a Material Adverse Effect.

         6.10     NO BURDENSOME RESTRICTIONS.

         No Requirement of Law or Contractual Obligation of the Parent or any
of its Subsidiaries would be reasonably expected to have a Material Adverse
Effect.

         6.11     TAXES.

         Each of the Parent and its Subsidiaries (a) has filed or caused to be
filed all United States federal income tax returns and all other material tax
returns which, to the best knowledge of the Credit Parties, are required to be
filed and (b) has paid (i) all taxes shown to be due and payable on said
returns, (ii) all taxes shown to be due and payable on any assessments of which
it has received notice made against it or any of its property and (c) all other
taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than any (x) taxes, fees or other charges with
respect to which the failure to pay, in the aggregate, would not have a
Material Adverse Effect or (y) taxes, fees or other charges the amount or
validity of which are currently being contested and with respect to which
reserves in conformity with GAAP have been provided on the books of such
Person), and no tax Lien (other than a Permitted Lien) has been filed, and, to
the best knowledge of the Credit Parties, no claim is being asserted, with
respect to any such tax, fee or other charge.

         6.12     ERISA

         Except as would not reasonably be expected to have a Material Adverse
Effect:

                  (a)      During the five (5) year period prior to the date on
         which this representation is made or deemed made: (i) no ERISA Event
         has occurred, and, to the best knowledge of the Credit Parties, no
         event or condition has occurred or exists as a result of which any
         ERISA Event could reasonably be expected to occur, with respect to any
         Plan; (ii) no "accumulated funding deficiency," as such term is
         defined in Section 302 of ERISA and Section 412 of the Code, whether
         or not waived, has occurred with respect to any Plan; (iii) each Plan
         has been maintained, operated, and funded in compliance with its own
         terms and in material compliance with the provisions of ERISA, the
         Code, and any other applicable federal or state laws; and (iv) no lien
         in favor of the PBGC or a Plan has arisen or is reasonably likely to
         arise on account of any Plan.

                  (b)      The actuarial present value of all "benefit
         liabilities" (as defined in Section 4001(a)(16) of ERISA), whether or
         not vested, under each Single Employer Plan, as of the last annual
         valuation date prior to the date on which this representation is made
         or deemed made (determined, in each case, in accordance with Financial
         Accounting Standards Board Statement 87, utilizing the actuarial
         assumptions used in such Plan's most recent actuarial


                                      51
<PAGE>   57
         valuation report), did not exceed as of such valuation date the fair
         market value of the assets of such Plan.

                  (c)      Neither the Parent, nor any of its Subsidiaries nor
         any ERISA Affiliate has incurred, or, to the best knowledge of the
         Credit Parties, could be reasonably expected to incur, any withdrawal
         liability under ERISA to any Multiemployer Plan or Multiple Employer
         Plan. Neither the Parent, nor any of its Subsidiaries nor any ERISA
         Affiliate would become subject to any withdrawal liability under ERISA
         if the Parent, any of its Subsidiaries or any ERISA Affiliate were to
         withdraw completely from all Multiemployer Plans and Multiple Employer
         Plans as of the valuation date most closely preceding the date on
         which this representation is made or deemed made. Neither the Parent,
         nor any of its Subsidiaries nor any ERISA Affiliate has received any
         notification that any Multiemployer Plan is in reorganization (within
         the meaning of Section 4241 of ERISA), is insolvent (within the
         meaning of Section 4245 of ERISA), or has been terminated (within the
         meaning of Title IV of ERISA), and no Multiemployer Plan is, to the
         best knowledge of the Credit Parties, reasonably expected to be in
         reorganization, insolvent, or terminated.

                  (d)      No prohibited transaction (within the meaning of
         Section 406 of ERISA or Section 4975 of the Code) or breach of
         fiduciary responsibility has occurred with respect to a Plan which has
         subjected or may subject the Parent, any of its Subsidiaries or any
         ERISA Affiliate to any liability under Sections 406, 409, 502(i), or
         502(l) of ERISA or Section 4975 of the Code, or under any agreement or
         other instrument pursuant to which the Parent, any of its Subsidiaries
         or any ERISA Affiliate has agreed or is required to indemnify any
         person against any such liability.

                  (e)      Neither the Parent, nor any of its Subsidiaries, nor
         any ERISA Affiliate has any material liability with respect to
         "expected post-retirement benefit obligations" within the meaning of
         the Financial Accounting Standards Board Statement 106. Each Plan
         which is a welfare plan (as defined in Section 3(1) of ERISA) to which
         Sections 601-609 of ERISA and Section 4980B of the Code apply has been
         administered in compliance in all material respects of such sections.

         6.13     GOVERNMENTAL REGULATIONS, ETC.

                  (a)      No part of the proceeds of the Loans will be used,
         directly or indirectly, for the purpose of purchasing or carrying any
         "margin stock" within the meaning of Regulation U, or for the purpose
         of purchasing or carrying or trading in any securities. If requested
         by any Lender or the Agent, the Borrowers will furnish to the Agent
         and each Lender a statement to the foregoing effect in conformity with
         the requirements of FR Form U-1 referred to in said Regulation U. No
         indebtedness being reduced or retired out of the proceeds of the Loans
         was or will be incurred for the purpose of purchasing or carrying any
         margin stock within the meaning of Regulation U or any "margin
         security" within the meaning of Regulation T. None of the transactions
         contemplated by this Credit Agreement (including, without limitation,
         the direct or indirect use of the proceeds of the Loans) will violate
         or result in a violation of the Securities Act of 1933, as amended, or
         the Securities Exchange Act of 1934, as amended, or regulations issued
         pursuant thereto, or Regulation D, O, T, U or X.

                                      52
<PAGE>   58
                  (b)      Neither the Parent, nor any of its Subsidiaries, is
         subject to regulation under the Public Utility Holding Company Act of
         1935, the Federal Power Act or the Investment Company Act of 1940,
         each as amended. In addition, neither the Parent, nor any of its
         Subsidiaries, is (i) an "investment company" registered or required to
         be registered under the Investment Company Act of 1940, as amended,
         and is not controlled by such a company, or (ii) a "holding company",
         or a "subsidiary company" of a "holding company", or an "affiliate" of
         a "holding company" or of a "subsidiary" of a "holding company",
         within the meaning of the Public Utility Holding Company Act of 1935,
         as amended.

                  (c)      Each of the Parent and its Subsidiaries has obtained
         all licenses, permits, franchises or other governmental authorizations
         necessary to the ownership of its respective Property and to the
         conduct of its business, other than licenses, permits, franchises and
         other governmental authorizations where the failure to obtain the same
         would not reasonably be expected to have a Material Adverse Effect.

                  (d)      Neither the Parent, nor any of its Subsidiaries is
         in violation of any applicable statute, regulation or ordinance of the
         United States of America, or of any state, city, town, municipality,
         county or any other jurisdiction, or of any agency thereof (including
         without limitation, environmental laws and regulations), which
         violation would reasonably be expected to have a Material Adverse
         Effect.

                  which the Credit Parties have received consideration in
                  excess of $5,000,000 for the sale of Receivables) if the
                  amount in default with respect thereto is in excess of
                  $5,000,000; or

                           (ii)     With respect to other Indebtedness (other
                  than Indebtedness outstanding under this Credit Agreement) of
                  the Parent or any of its Subsidiaries in an aggregate amount
                  in excess of $5,000,000, (A) the Parent or any of its
                  Subsidiaries shall default in any payment (beyond the
                  applicable grace period with respect thereto, if any) with
                  respect to any such Indebtedness; or (B) any such
                  Indebtedness shall be declared due and payable, or required
                  to be prepaid other than by a regularly scheduled required
                  prepayment, prior to the stated maturity thereof; or

                  (g)      Judgments. The Parent or any of its Subsidiaries
         shall fail within sixty (60) days of the date due and payable to pay,
         bond or otherwise discharge any judgment, settlement or order for the
         payment of money which judgment, settlement or order when aggregated
         with all other such judgments, settlements or orders due and unpaid at
         such time, exceeds $5,000,000 and which is not stayed on appeal (or
         for which no motion for stay is pending) or is not otherwise being
         executed; or

                  (h)      ERISA. Any of the following events or conditions, if
         such event or condition would reasonably be expected to have a
         Material Adverse Effect: (1) any "accumulated funding deficiency," as
         such term is defined in Section 302 of ERISA and Section 412 of the
         Code, whether or not waived, shall exist with respect to any Plan, or
         any lien shall arise on the assets of the Parent or any of its
         Subsidiaries or any ERISA Affiliate in favor of the PBGC or a Plan;
         (2) an ERISA Event shall occur with respect to a Single Employer Plan,
         which is, in the reasonable opinion of the Agent, likely to result in
         the termination of such Plan for purposes of Title IV of ERISA; (3) an
         ERISA Event shall occur with respect to a Multiemployer Plan or
         Multiple Employer Plan, which is, in the reasonable opinion of the
         Agent, likely to result in (i) the termination of such Plan for
         purposes of Title IV of ERISA, or (ii) the Parent or any of its
         Subsidiaries or any ERISA Affiliate incurring any liability in
         connection with a withdrawal from, reorganization of (within the
         meaning of Section 4241 of ERISA), or insolvency of (within the
         meaning of Section 4245 of ERISA) such Plan; or (4) any prohibited
         transaction (within the meaning of Section 406 of ERISA or Section
         4975 of the Code) or breach of fiduciary responsibility shall occur
         which may subject the Parent or any of its Subsidiaries or any ERISA
         Affiliate to any liability under Sections 406, 409, 502(i), or 502(l)
         of ERISA or Section 4975 of the Code, or under any agreement or other
         instrument pursuant to which the Parent or any of its Subsidiaries or
         any ERISA Affiliate has agreed or is required to indemnify any person
         against any such liability; or

                  (i)      Ownership. There shall occur a Change of Control.

<PAGE>   74
                  (j)      Settlement Agreements. There shall occur any
         development in arrangements of any Credit Party with a Settlement Bank
         which would reasonably be expected to have a Material Adverse Effect.

                  (k)      VISA/MasterCard. Any Credit Party shall (i) fail to
         comply with any requirement of VISA/MasterCard necessary or desirable
         to the conduct of its business, the failure to comply with which would
         reasonably be expected to have a Material Adverse Effect, (ii) fail to
         fulfill any applicable requirement to be a registered member service
         provider or member, as applicable, with VISA/MasterCard, the failure
         of which would reasonably be expected to have a Material Adverse
         Effect, or (iii) fail to be registered as a member service provider
         with each clearing bank with which it conducts business and is
         required to be so registered which failure would reasonably be
         expected to have a Material Adverse Effect.

         9.2      ACCELERATION; REMEDIES.

         Upon the occurrence and during the continuance of an Event of Default,
the Agent shall, upon the request and direction of the Required Lenders, by
written notice to the Borrowers take any of the following actions:

                  (a)      Termination of Commitments. Declare the Commitments
         terminated whereupon the Commitments shall be immediately terminated.

                  (b)      Acceleration. Declare the unpaid principal of and
         any accrued interest in respect of all Loans, any reimbursement
         obligations arising from drawings under Letters of Credit and any and
         all other indebtedness or obligations of any and every kind owing by
         the Credit Parties 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 Borrowers.

                  (c)      Cash Collateral. Direct the Credit Parties to pay
         (and the Credit Parties agree 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 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 presentment,


                                      69

demand, protest or the giving of any notice or other action by the Agent or the
Lenders, all of which are hereby waived by the Credit Parties.


                                   SECTION 10
                               AGENCY PROVISIONS

         10.1     APPOINTMENT.

         Each Lender hereby designates and appoints Bank of America as
administrative agent (in such capacity, the "Agent") of such Lender to act as
specified herein and the other Credit Documents, and each such Lender hereby
authorizes the Agent as the Agent for such Lender, to take such action on its
behalf under the provisions of this Credit Agreement and the other Credit
Documents and to exercise such powers and perform such duties as are expressly
delegated by the terms hereof and of the other Credit Documents, together with
such other powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere herein and in the other Credit Documents,
the Agent shall not have any duties or responsibilities, except those expressly
set forth herein and therein, or any fiduciary relationship with any Lender,
and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Credit Agreement or any of the other Credit
Documents, or shall otherwise exist against the Agent. The provisions of this
Section are solely for the benefit of the Agent and the Lenders and the Credit
Parties shall not have any rights as a third party beneficiary of the
provisions hereof. In performing its functions and duties under this Credit
Agreement and the other Credit Documents, the Agent shall act solely as Agent
of the Lenders and does not assume and shall not be deemed to have assumed any
obligation or relationship of agency or trust with or for the Credit Parties or
any of their Affiliates.

         10.2     DELEGATION OF DUTIES.

         The Agent may execute any of their respective duties hereunder or
under the other Credit Documents by or through agents or attorneys-in-fact and
shall be entitled to advice of counsel concerning all matters pertaining to
such duties. The Agent shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

         10.3     EXCULPATORY PROVISIONS.

         The Agent and its officers, directors, employees, agents,
attorneys-in-fact or affiliates shall not be (a) liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection
herewith or in connection with any of the other Credit Documents (except for
its or such Person's own gross negligence or willful misconduct), or (b)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any of the Credit Parties contained
herein or in any of the other Credit Documents or in any certificate, report,
document, financial statement or other written or oral statement referred to or
provided for in, or received by the Agent under or in connection herewith or in
connection with the other Credit Documents, or enforceability or sufficiency
therefor of any of the other Credit Documents, or for any failure of the Credit
Parties to perform their obligations hereunder or thereunder. The Agent shall
not be responsible to any Lender for the effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Credit Agreement, or any
of the other Credit Documents or for any representations, warranties, recitals
or statements made herein or therein or made by the Credit


                                      70
<PAGE>   76
Parties in any written or oral statement or in any financial or other
statements, instruments, reports, certificates or any other documents in
connection herewith or therewith furnished or made by the Agent to the Lenders
or by or on behalf of the Credit Parties to the Agent or any Lender or be
required to ascertain or inquire as to the performance or observance of any of
the terms, conditions, provisions, covenants or agreements contained herein or
therein or as to the use of the proceeds of the Loans or the use of the Letters
of Credit or of the existence or possible existence of any Default or Event of
Default or to inspect the properties, books or records of the Credit Parties or
their Affiliates.

         10.4     RELIANCE ON COMMUNICATIONS.

         The Agent shall be entitled to rely, and shall be fully protected in
relying, upon any note, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Borrowers, independent accountants and other experts
selected by the Agent with reasonable care). The Agent may deem and treat the
Lenders as the owner of their respective interests hereunder for all purposes
unless a written notice of assignment, negotiation or transfer thereof shall
have been filed with the Agent in accordance with Section 11.3(b) hereof. The
Agent shall be fully justified in failing or refusing to take any action under
this Credit Agreement or under any of the other Credit Documents unless it
shall first receive such advice or concurrence of the Required Lenders as it
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense which may be incurred by it
by reason of taking or continuing to take any such action. The Agent shall in
all cases be fully protected in acting, or in refraining from acting, hereunder
or under any of the other Credit Documents in accordance with a request of the
Required Lenders (or to the extent specifically provided in Section 11.6, all
the Lenders) and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders (including their successors and
assigns).

         10.5     NOTICE OF DEFAULT.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default hereunder unless the Agent has
received notice from a Lender or one of the Credit Parties referring to the
Credit Document, describing such Default or Event of Default and stating that
such notice is a "notice of default." In the event that the Agent receives such
a notice, the Agent shall give prompt notice thereof to the Lenders. The Agent
shall take such action with respect to such Default or Event of Default as
shall be directed by the Required Lenders.

         10.6     NON-RELIANCE ON AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that each of the Agent and its
officers, directors, employees, agents, attorneys-in-fact or affiliates has not
made any representations or warranties to it and that no act by the Agent or
any affiliate thereof hereinafter taken, including any review of the affairs of
the Credit Parties or any of their Affiliates, shall be deemed to constitute
any representation or warranty by the Agent to any Lender. Each Lender
represents to the Agent that it has, independently and without reliance upon
the Agent or any other Lender, and based on such


                                      71
<PAGE>   77
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, assets, operations, property, financial
and other conditions, prospects and creditworthiness of the Credit Parties or
their Affiliates and made its own decision to make its Loans hereunder and
enter into this Credit Agreement. Each Lender also represents that it will,
independently and without reliance upon the Agent or any other Lender, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Credit Agreement, and to make such
investigation as it deems necessary to inform itself as to the business,
assets, operations, property, financial and other conditions, prospects and
creditworthiness of the Credit Parties and their Affiliates. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Agent hereunder, the Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, assets, property, financial or other
conditions, prospects or creditworthiness of the Credit Parties or their
respective Affiliates which may come into the possession of the Agent or any of
its officers, directors, employees, agents, attorneys-in-fact or affiliates.

         10.7     INDEMNIFICATION.

         The Lenders agree to indemnify the Agent in its capacity as such (to
the extent not reimbursed by the Credit Parties and without limiting the
obligation of the Credit Parties to do so), ratably according to their
respective Commitments (or if the Commitments have expired or been terminated,
in accordance with the respective principal amounts of outstanding Loans and
Participation Interests of the Lenders), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind whatsoever which may at any
time (including without limitation at any time following the final payment of
all of the obligations of the Credit Parties hereunder and under the other
Credit Documents) be imposed on, incurred by or asserted against the Agent in
its capacity as such in any way relating to or arising out of this Credit
Agreement or the other Credit Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by the Agent under or in connection with
any of the foregoing; provided that no Lender shall be liable for the payment
of any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from the
gross negligence or willful misconduct of the Agent. If any indemnity furnished
to the Agent for any purpose shall, in the opinion of the Agent, be
insufficient or become impaired, the Agent may call for additional indemnity
and cease, or not commence, to do the acts indemnified against until such
additional indemnity is furnished. The agreements in this Section shall survive
the repayment of the Loans, LOC Obligations and other obligations under the
Credit Documents and the termination of the Commitments hereunder.

         10.8     AGENT IN ITS INDIVIDUAL CAPACITY.

         The Agent and its affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Parent, its Subsidiaries
or their respective Affiliates as though the Agent were not the Agent
hereunder. With respect to the Loans made by and all obligations of the Credit
Parties hereunder and under the other Credit Documents, the Agent shall have
the same rights and powers under this Credit Agreement as any Lender and may
exercise the same as though


                                      72
<PAGE>   78
it were not the Agent, and the terms "Lender" and "Lenders" shall include the
Agent in its individual capacity.

         10.9     SUCCESSOR AGENT.

         The Agent may, at any time, resign upon twenty (20) days' written
notice to the Borrowers and the Lenders. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Agent. 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 notice of
resignation, then the resignation of the retiring Agent shall nonetheless
thereupon be effective and the retiring Agent shall select a successor Agent
provided such successor is a Lender hereunder or a commercial bank organized
under the laws of the United States of America or of any State thereof and has
a combined capital and surplus of at least $400,000,000 (or if no such
successor shall have been so appointed by the retiring Agent and shall have
accepted such appointment, then the Lenders shall perform all obligations of
the retiring Agent hereunder and under the other Credit Documents until such
time, if any, as a successor Agent shall have been appointed and shall have
accepted such appointment as provided for above). Upon the acceptance of any
appointment as Agent hereunder by a successor, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations as Agent, as appropriate, under this Credit
Agreement and the other Credit Documents and the provisions of this Section
10.9 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent under this Credit Agreement.

         11.2     RIGHT OF SET-OFF.

         In addition to any rights now or hereafter granted under applicable
law or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default, each Lender is authorized at any time and
from time to time, without presentment, demand, protest or other notice of any
kind (all of which rights being hereby expressly waived), to set-off and to
appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Lender (including, without
limitation branches, agencies or Affiliates of such Lender wherever located) to
or for the credit or the account of the Credit Parties against obligations and
liabilities of such Person to such Lender hereunder, under the Notes, the other
Credit Documents or otherwise, irrespective of whether such Lender shall have
made any demand hereunder and although such obligations, liabilities or claims,
or any of them, may be contingent or unmatured, and any such set-off shall be
deemed to have been made immediately upon the occurrence of an Event of Default
even though such charge is made or entered on the books of such Lender
subsequent thereto. Any Person purchasing a participation in the Loans and
Commitments hereunder pursuant to Section 3.14 or Section 11.3(d) may exercise
all rights of set-off with respect to its participation interest as fully as if
such Person were a Lender hereunder. Notwithstanding the foregoing, no Lender
shall have a right of setoff with respect to (a) deposits of a Credit Party in
Settlement Accounts and deposits in other accounts of a Credit Party which are
being held by such Credit Party as a fiduciary on behalf of a merchant pending
resolution of a dispute in the ordinary course of business and (b) amounts held
by a Credit Party as a servicer or in any other fiduciary capacity with respect
to a Permitted Receivables Financing, to the extent such Permitted Receivables
Financing requires such amounts to be so held.

         11.3     BENEFIT OF AGREEMENT.

                  (a)      Generally. 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 no Credit
         Party may assign or transfer any of its interests 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, provided however that nothing herein shall prevent or
         prohibit any Lender from (i) pledging its Loans hereunder to a Federal
         Reserve Bank in support of borrowings made by such Lender from such
         Federal Reserve Bank, or (ii) granting assignments or selling
         participations in such Lender's Loans and/or Commitments hereunder to
         its parent company and/or to any Affiliate or Subsidiary of such
         Lender.

                  (b)      Assignments. Each Lender may assign all or a portion
         of its rights and obligations hereunder, pursuant to an assignment
         agreement substantially in the form of Exhibit 11.3(b), to any
         Eligible Assignee; provided that (i) any such assignment (other than
         any assignment to an existing Lender) shall be in a minimum aggregate
         amount of $1,000,000 (or, if less, the remaining amount of the
         Commitment being assigned by such Lender) of the Commitments and in an
         integral multiple of $1,000,000 above such amount and (ii) each such
         assignment shall be of a constant, not varying, percentage of all such
         Lender's rights and obligations under this Credit Agreement. Any
         assignment hereunder shall be effective upon delivery to the Agent of
         written notice of the assignment together with a transfer fee of
         $3,500 payable to the Agent for its own account from and after the
         later of (i) the effective date specified in the applicable assignment
         agreement and (ii) the date of recording of such assignment in the
         Register pursuant to the terms of subsection (c) below. The assigning
         Lender will give prompt notice to the Agent and the Borrowers of any
         such assignment. Upon the effectiveness of any such assignment (and
         after notice to, and (to the extent required pursuant to the terms
         hereof), with the consent of, the Borrowers as provided herein), the
         assignee shall become a "Lender" for all purposes of this Credit
         Agreement and the other Credit Documents and, to the extent of such
         assignment, the assigning Lender shall be relieved of its obligations
         hereunder to the extent of the Loans and Commitment components being
         assigned. Along such lines the Borrowers agree that upon notice of any
         such assignment and surrender of the appropriate Note or Notes, they
         will promptly provide to the assigning Lender and to the assignee
         separate promissory notes in the amount of their respective interests
         substantially in the form of the original Note (but with notation
         thereon that it is given in substitution for and replacement of the
         original Note or any replacement notes thereof). By executing and
         delivering an assignment agreement in accordance with this Section
         11.3(b), the assigning Lender thereunder and the assignee thereunder
         shall be deemed to confirm to and agree with each other and the other
         parties hereto as follows: (i) such assigning Lender warrants that it
         is the legal and beneficial owner of the interest being assigned
         thereby free and clear of any adverse claim; (ii) except as set forth
         in clause (i) above, such assigning Lender makes no representation or
         warranty and assumes no responsibility with respect to any statements,
         warranties or representations made in or in connection with this
         Credit Agreement, any of the other Credit Documents or any other
         instrument or document furnished pursuant hereto or thereto, or the
         execution, legality, validity, enforceability, genuineness,
         sufficiency or value of this Credit Agreement, any of the other Credit
         Documents or any other instrument or document furnished pursuant
         hereto


                                      75
<PAGE>   81
         or thereto or the financial condition of the Credit Parties or any of
         their Affiliates or the performance or observance by the Credit
         Parties of any of their obligations under this Credit Agreement, any
         of the other Credit Documents or any other instrument or document
         furnished pursuant hereto or thereto; (iii) such assignee represents
         and warrants that it is legally authorized to enter into such
         assignment agreement; (iv) such assignee confirms that it has received
         a copy of this Credit Agreement, the other Credit Documents and such
         other documents and information as it has deemed appropriate to make
         its own credit analysis and decision to enter into such assignment
         agreement; (v) such assignee will independently and without reliance
         upon the Agent, such assigning Lender or any other Lender, and based
         on such documents and information as it shall deem appropriate at the
         time, continue to make its own credit decisions in taking or not
         taking action under this Credit Agreement and the other Credit
         Documents; (vi) such assignee appoints and authorizes the Agent to
         take such action on its behalf and to exercise such powers under this
         Credit Agreement or any other Credit Document as are delegated to the
         Agent by the terms hereof or thereof, together with such powers as are
         reasonably incidental thereto; and (vii) such assignee agrees that it
         will perform in accordance with their terms all the obligations which
         by the terms of this Credit Agreement and the other Credit Documents
         are required to be performed by it as a Lender.

                  (c)      Maintenance of Register. The Agent shall maintain at
         one of its offices a copy of each Lender assignment agreement
         delivered to it in accordance with the terms of subsection (b) above
         and a register for the recordation of the identity of the principal
         amount, type and Interest Period of each Loan outstanding hereunder,
         the names, addresses and the Commitments of the Lenders pursuant to
         the terms hereof from time to time (the "Register"). The Agent will
         make reasonable efforts to maintain the accuracy of the Register and
         to promptly update the Register from time to time, as necessary. The
         entries in the Register shall be conclusive in the absence of manifest
         error and the Borrowers, the Agent and the Lenders may treat each
         Person whose name is recorded in the Register pursuant to the terms
         hereof as a Lender hereunder for all purposes of this Credit
         Agreement. The Register shall be available for inspection by the
         Borrowers and each Lender, at any reasonable time and from time to
         time upon reasonable prior notice.

                  (d)      Participations. Each Lender may sell, transfer,
         grant or assign participations in all or any part of such Lender's
         interests and obligations hereunder; provided that (i) such selling
         Lender shall remain a "Lender" for all purposes under this Credit
         Agreement (such selling Lender's obligations under the Credit
         Documents remaining unchanged) and the participant shall not
         constitute a Lender hereunder, (ii) no such participant shall have, or
         be granted, rights to approve any amendment or waiver relating to this
         Credit Agreement or the other Credit Documents except to the extent
         any such amendment or waiver would (A) reduce the principal of or rate
         of interest on or Fees in respect of any Loans or other Obligations in
         which the participant is participating, (B) postpone the date fixed
         for any payment of principal (including any extension of the
         Termination Date or the waiver of any mandatory prepayment), interest
         or Fees in which the participant is participating or (C) release all
         or substantially all of (I) the Guarantors from the Guaranty
         Obligations hereunder or (II) the collateral securing the Obligations,
         (iii) sub-participations by the participant (except to an affiliate,
         parent company or affiliate of a parent company of the participant)
         shall be prohibited and (iv) prompt written notice of such
         participation shall be given to the Borrowers if the applicable
         participant is engaged in a CCTP Business and


                                      76
<PAGE>   82
         could reasonably be considered a competitor of a Borrower. In the case
         of any such participation, the participant shall not have any rights
         under this Credit Agreement or the other Credit Documents (the
         participant's rights against the selling Lender in respect of such
         participation to be those set forth in the participation agreement
         with such Lender creating such participation) and all amounts payable
         by the Borrowers hereunder shall be determined as if such Lender had
         not sold such participation, provided, however, that such participant
         shall be entitled to receive additional amounts under Sections 3.6,
         3.8, 3.9, 3.10 and 3.11 on the same basis as if it were a Lender.

         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 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 the Credit Parties in any case shall entitle the Credit Parties 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     PAYMENT OF EXPENSES, ETC.

         The Credit Parties joint and severally agree to: (i) pay all
reasonable out-of-pocket costs and expenses (A) of the Agent in connection with
the negotiation, preparation, execution and delivery and administration of this
Credit Agreement and the other Credit Documents and the documents and
instruments referred to therein (including, without limitation, the reasonable
fees and expenses of Moore & Van Allen, PLLC, special counsel to the Agent and
any amendment, waiver or consent relating hereto and thereto including, but not
limited to, any such amendments, waivers or consents resulting from or related
to any work-out, renegotiation or restructure relating to the performance by
the Credit Parties under this Credit Agreement and (B) of the Agent and the
Lenders in connection with enforcement of the Credit Documents and the
documents and instruments referred to therein (including, without limitation,
in connection with any such enforcement, the reasonable fees and disbursements
of counsel for the Agent and each of the Lenders); (ii) pay and hold each of
the Lenders harmless from and against any and all present and future stamp and
other similar taxes with respect to the foregoing matters and save each of the
Lenders harmless from and against any and all liabilities with respect to or
resulting from any delay or omission (other than to the extent attributable to
such Lender) to pay such taxes; and (iii) indemnify each of the Agent and each
Lender, its officers, directors, employees, representatives and agents from and
hold each of them harmless against any and all losses, liabilities, claims,
damages or expenses incurred by any of them as a result of, or arising out of,
or in any way related to, or by reason of (A) any investigation, litigation or
other proceeding (whether or not any Lender is a party thereto) related to the
entering into and/or performance of any Credit Document or the use of proceeds
of any Loans or other Extensions of Credit hereunder or the consummation of any
other transactions contemplated in any Credit Document, including, without
limitation, the reasonable fees and disbursements of counsel incurred in
connection with any such investigation, litigation or other proceeding or (B)
the


                                      77
<PAGE>   83
presence or Release of any Materials of Environmental Concern at, under or
from any Property owned, operated or leased by the Credit Parties or any of
their Subsidiaries, or the failure by the Credit Parties or any of their
Subsidiaries to comply with any Environmental Law (but excluding, in the case
of either of clause (A) or (B) above, any such losses, liabilities, claims,
damages or expenses to the extent incurred by reason of gross negligence or
willful misconduct on the part of the Person to be indemnified).
Notwithstanding the foregoing provisions of this Section 11.5, the Credit
Parties shall not be obligated to reimburse and/or indemnify a Lender for the
fees and disbursements of counsel for such Lender to the extent such fees and
disbursements relate to legal work that would reasonably be deemed to be
redundant of legal work performed by counsel for the Agent and to serve no
reasonable, independent purpose.

         11.6     AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement nor any of the other Credit Documents,
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 Borrowers, provided, however, that no such amendment,
change, waiver, discharge or termination shall, without the consent of each
Lender directly affected thereby,

                  (a)      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) on any Loan or other
         Extension of Credit or Fees hereunder,

                  (b)      extend (i) the Termination Date, (ii) the final
         maturity of any Loan or otherwise postpone any other date fixed for
         any payment of principal, or (iii) the time of payment of any
         reimbursement obligation, or any portion thereof, arising from
         drawings under Letters of Credit,

                  (c)      reduce the principal amount on any Loan or other
         Extension of Credit;

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

                  (e)      release all or substantially all of (i) the
         Guarantors from the Guaranty Obligations hereunder or (ii) the
         collateral securing the Obligations,

                  (f)      amend, modify or waive any provision of this Section
         11.6 or Section 3.6, 3.10, 3.11, 3.12, 3.13, 9.1(a), 11.2, 11.3, 11.5
         or 11.9,

                  (g)      reduce any percentage specified in, or otherwise
         modify, the definition of "Required Lenders" or

                  (h)      consent to the assignment or transfer by a Borrower
         of any of its rights and obligations under (or in respect of) the
         Credit Documents to which it is a party.


                                      78

         In addition to the foregoing, no provision of Section 2.2 may be
amended without the consent of the Fronting Bank and no provision of Section 10
may be amended without the consent of the Agent.

         Notwithstanding the fact that the consent of all of the Lenders is
required in certain circumstances as set forth above, (x) each Lender is
entitled to vote as such Lender sees fit on any reorganization plan that
affects the Loans or the Letters of Credit, and each Lender acknowledges that
the provisions of Section 1126(c) of the Bankruptcy Code supercede the
unanimous consent provisions set forth herein and (y) the Required Lenders may
consent to all on a Credit Party to use cash collateral in the context of a
bankruptcy or insolvency proceeding.

         11.7     COUNTERPARTS.

         This Credit Agreement may be executed in any number of counterparts,
each of which when 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 Credit Agreement to produce or account for more than
one such counterpart.

         11.8     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 Credit Agreement.

         11.9     SURVIVAL.

         All indemnities set forth herein, including, without limitation, in
Section 2.2(i), 3.9, 3.11, 7.8, 10.7 and 11.5 shall survive the execution and
delivery of this Credit Agreement, the making of the Loans, the issuance of the
Letters of Credit, the repayment of the Loans, LOC Obligations and other
obligations under the Credit Documents and the termination of the Commitments
hereunder, and all representations and warranties made by the Credit Parties

         11.10    GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE.

                  (a)      THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS
         AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER
         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 Credit Agreement or any other Credit Document may be
         brought in the courts of the State of New York, or of the United
         States for the Southern District of New York, and, by execution and
         delivery of this Credit Agreement, the Credit Parties hereby
         irrevocably accept for themselves and in respect of their property,
         generally and unconditionally, the nonexclusive jurisdiction of such
         courts. The Agent and the Credit Parties further irrevocably consent
         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
         set out for notices pursuant to Section 11.1, such service to become
         effective three (3) Business

         Days after such mailing. Nothing herein shall affect the right of any
         party hereto to serve process in any other manner permitted by law or
         to commence legal proceedings or to otherwise proceed against the
         Credit Parties in any other jurisdiction.

                  (b)      The Agent and the Credit Parties hereby irrevocably
         waive any objection which they 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 Credit Agreement or any other Credit
         Document 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

                  (c)      TO THE EXTENT PERMITTED BY LAW, EACH OF THE AGENT,
         THE LENDERS AND THE CREDIT PARTIES HEREBY IRREVOCABLY WAIVE ALL RIGHT

         OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT
         DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         11.11    SEVERABILITY.

         If any provision of any of the Credit Documents 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; provided, however, that such Credit Documents shall be reformed in
such a manner so that they reflect, to the fullest extent permitted by law, the
intent of the parties with respect to the transactions contemplated hereby and
the relative rights and obligations of the parties hereunder.

         11.12    ENTIRETY.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede

commitment letters or correspondence relating to the Credit Documents or the
transactions contemplated herein and therein.

         11.13    BINDING EFFECT; AMENDMENT AND RESTATEMENT; TERMINATION.

                  (a)      This Credit Agreement shall become effective at such
         time, on or after the Closing Date, that the conditions precedent set
         forth in Section 5.1 have been satisfied and when it shall have been
         executed by each of the Credit Parties and the Agent, and the Agent
         shall have received copies of the signature pages hereto (telefaxed or
         otherwise) which, when taken together, bear the signatures of each
         Lender (including the Fronting Bank), and thereafter this Credit
         Agreement shall be binding upon and inure to the benefit of each
         Credit Party, each Lender (including the Fronting Bank) and the Agent,
         together with their permitted successors and assigns. The Credit
         Parties and the Lenders (including the Fronting Bank) each hereby
         agrees that, at such time as this Credit


                                      80
<PAGE>   86
         Agreement shall have become effective pursuant to the terms of the
         immediately preceding sentence, (i) the Existing Credit Agreement
         automatically shall be deemed amended and restated in its entirety by
         this Credit Agreement, and any obligations and commitments outstanding
         under the Original Credit Agreement shall be governed by the terms of
         this Credit Agreement (as such obligations or commitments may be
         modified or amended hereunder) and (ii) all of the promissory notes
         executed by the Borrowers in connection with the Existing Credit
         Agreement automatically shall be substituted and replaced by the
         amended and restated promissory notes executed in connection with this
         Credit Agreement, and the Lenders holding such prior notes agree
         promptly to return them to the Borrowers.

                  (b)      The term of this Credit Agreement shall be until no
         Loans, LOC Obligations or any other amounts payable hereunder or under
         any of the other Credit Documents shall remain outstanding and until
         all of the Commitments hereunder shall have expired or been
         terminated.

         11.14    CONFIDENTIALITY.

         The Agent and the Lenders agree to keep confidential (and to cause
their respective affiliates, officers, directors, employees, agents and
representatives to keep confidential) all information, materials and documents
furnished to the Agent or any such Lender by or on behalf of the Credit Parties
(whether before or after the Closing Date) which relates to the Credit Parties
or any of their Subsidiaries (the "Information"). Notwithstanding the
foregoing, the Agent and each Lender shall be permitted to disclose Information
(i) to its affiliates, officers, directors, employees, agents and
representatives on a "need to know" basis in connection with their
participation in any of the transactions evidenced by this Credit Agreement or
any other Credit Documents or the administration of this Credit Agreement or
any other Credit Documents; (ii) to the extent required by applicable laws and
regulations or by any subpoena or similar legal process, or requested by any
Governmental Authority; provided that to the extent any such request by a
Governmental Authority is made other than in connection with banking regulatory
or oversight matters, then the Agent or such Lender shall use its reasonable
best efforts to give the Borrowers notice of such request and the opportunity
to object thereto; (iii) to the extent such Information (A) is or becomes
publicly available other than as a result of a breach (of which the Agent or
such Lender has knowledge) by any Person of a confidentiality agreement with
any Credit Party, (B) is or becomes available to the Agent or such Lender on a
non-confidential basis from a source other than the Credit Parties without a
breach (of which the Agent or such Lender has knowledge) by any Person of a
confidentiality agreement with any Credit Party or (C) was available to the
Agent or such Lender on a non-confidential basis prior to its disclosure to the
Agent or such Lender by the Credit Parties; (iv) to any assignee or participant
(or prospective assignee or participant) subject to an agreement containing
provisions substantially the same as those of this Section 11.14; or (v) to the
extent that the Borrowers shall have consented in writing to such disclosure.
Upon the request of Borrowers, following the satisfaction of all Obligations
hereunder, each Lender shall use its reasonable best efforts to either return
to the Borrowers all Information (to the extent still confidential) provided
hereunder and/or destroy all such Information and certify to the Borrowers such
destruction.
