                  Notwithstanding the above, if at any time there is a split in
         Debt Ratings between S&P and Moody's, (a) in the event of a single
         level split, the higher Debt Rating (i.e. the lower pricing) will apply
         and (b) in the event of a multiple level split, one level below the
         higher Debt Rating will apply.

                  The Applicable Margin for Eurodollar Loans, the Commitment
         Fees and the Utilization Fees shall, in each case, be determined and
         adjusted on the date (each a "Calculation Date") five Business Days
         after the date there is a change in the Borrower's Debt Rating. Each
         determination of the Applicable Margin shall be effective from one
         Calculation Date until the next Calculation Date. Any adjustment in the
         Applicable Margin shall be applicable to all existing Eurodollar Loans
         and Letters of Credit as well as any new Eurodollar Loans made or
         Letters of Credit issued.

                  The Borrower shall promptly deliver to the Agent, at the
         address set forth on Schedule 11.1 and at the Agency Services Address,
         information regarding any change in the Borrower's Debt Rating that
         would change the existing Pricing Level pursuant to the preceding
         paragraph.

                  "Approved Officer" means the president, a vice president, the
         treasurer or the assistant treasurer of the Borrowers or such other
         representative of the Borrowers as may be designated by any one of the
         foregoing with consent of the Agent.

                  "Bankruptcy Code" means the Bankruptcy Code in Title 11 of the
         United States Code, as amended, modified, succeeded or replaced from
         time to time.

                  "Base Rate" means, for any day, the rate per annum equal to
         the greater of (a) the Federal Funds Rate in effect on such day plus
         1/2 of 1% or (b) the Prime Rate in effect on such day. If for any
         reason the Agent shall have determined (which determination shall be
         conclusive absent manifest error) that it is unable after due inquiry
         to ascertain the






                                       2
<PAGE>   7

         Federal Funds Rate for any reason, including the inability or failure
         of the Agent to obtain sufficient quotations in accordance with the
         terms hereof, the Base Rate shall be determined without regard to
         clause (a) of the first sentence of this definition until the
         circumstances giving rise to such inability no longer exist. Any change
         in the Base Rate due to a change in the Prime Rate or the Federal Funds
         Rate shall be effective on the effective date of such change in the
         Prime Rate or the Federal Funds Rate, respectively.

                  "Base Rate Loan" means a Loan which bears interest based on
         the Base Rate.

                  "Borrowers" means, subject to Section 2.10, Duke Energy Field
         Services, LLC, a Delaware limited liability company and Duke Energy
         Field Services Corporation, a Delaware corporation and "Borrower" means
         either of them.

                  "Borrowers Obligations" means, without duplication, all of the
         obligations of the Borrowers to the Lenders and the Agent, whenever
         arising, under this Credit Agreement, the Notes, the LOC Documents or
         any of the other Credit Documents.

                  "Business Day" means any day other than a Saturday, a Sunday,
         a legal holiday or a day on which banking institutions are authorized
         or required by law or other governmental action to close in Dallas,
         Texas or New York, New York; provided that in the case of Eurodollar
         Loans, such day is also a day on which dealings between banks are

         or "group" (within the meaning of section 13(d) or 14(d) of the

                                      LOANS

         2.1 REVOLVING COMMITTED AMOUNT.

         Subject to the terms and conditions set forth herein, each Lender
severally agrees to make revolving loans to the Borrowers in Dollars, at any
time and from time to time, during the period from the Effective Date to the
Maturity Date (each a "Loan" and collectively the "Loans"); provided, however,
that (a) the sum of the aggregate amount of Loans outstanding plus the aggregate
amount of LOC Obligations outstanding shall not exceed the Revolving Committed
Amount and (b) with respect to each individual Lender, such Lender's pro rata
share of outstanding Loans plus such Lender's pro rata share of outstanding LOC
Obligations shall not exceed such Lender's Commitment Percentage of the
Revolving Committed Amount. Subject to the terms of this Credit Agreement, the
Borrowers may borrow, repay and reborrow Loans.

         2.2 LETTER OF CREDIT SUBFACILITY.

                  (a) Issuance. Subject to the terms and conditions hereof and
         of the LOC Documents, if any, and any other terms and conditions which
         the Issuing Lender may reasonably require (so long as such terms and
         conditions do not impose any financial obligation on or require any
         Lien (not otherwise contemplated by this Credit Agreement) to be given
         by a Borrower or conflict with any obligation of, or detract from any
         action which may be taken by the Borrowers or their Subsidiaries under
         this Credit Agreement), the Issuing Lender shall from time to time upon
         request issue, in Dollars, and the Lenders shall participate in,
         letters of credit (the "Letters of Credit") for the account of a
         Borrower or any of its Subsidiaries, from the Effective Date until the
         Maturity Date, in a form reasonably acceptable to the Issuing Lender;
         provided, however, that (i) the aggregate amount of LOC Obligations
         shall not at any time exceed the LOC Committed Amount, (ii) the sum of
         the aggregate amount of LOC Obligations outstanding plus Loans
         outstanding shall not exceed the Revolving Committed Amount and (iii)
         with respect to each individual Lender, the Lender's pro rata





                                       13
<PAGE>   18

         share of outstanding Loans plus its pro rata share of outstanding LOC
         Obligations shall not exceed such Lender's Commitment Percentage of the
         Revolving Committed Amount. The issuance and expiry date of each Letter
         of Credit shall be a Business Day. Except as otherwise expressly agreed
         upon by all the Lenders, no Letter of Credit shall have an expiry date
         extending beyond the Maturity Date. Each Letter of Credit shall be
         either (x) a standby letter of credit issued to support the obligations
         (including pension or insurance obligations), contingent or otherwise,
         of a Borrower, or (y) a commercial letter of credit in respect of the
         purchase of goods or services by a Borrower in the ordinary course of
         business. Each Letter of Credit shall comply with the related LOC
         Documents.

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

                  (c) Participations.

                           (i) Each Lender acknowledges that it shall
                  automatically acquire a participation in the liability of the
                  Issuing Lender under the Existing Letter of Credit in an
                  amount equal to its Commitment Percentage of such Existing
                  Letter of Credit.

                           (ii) Each Lender, upon issuance of a Letter of
                  Credit, shall be deemed to have purchased without recourse a
                  risk participation from the Issuing Lender in such Letter of
                  Credit and the obligations arising thereunder and any
                  collateral relating thereto, in each case in an amount equal
                  to its 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 Issuing Lender therefor and
                  discharge when due, its Commitment Percentage 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 Issuing Lender
                  has not been reimbursed as required hereunder or under any
                  such Letter of Credit, each such Lender shall pay to the
                  Issuing Lender its Commitment Percentage of such unreimbursed
                  drawing in same day funds on the day of notification by the
                  Issuing Lender of an unreimbursed drawing pursuant to the
                  provisions of subsection (d) hereof. The obligation of each
                  Lender to so reimburse the Issuing Lender shall be absolute
                  and unconditional and shall not be affected by the occurrence
                  of a Default, an Event of Default or any other occurrence or
                  event. Any such reimbursement shall not relieve or otherwise
                  impair the obligation of the Borrowers to reimburse the
                  Issuing Lender under any Letter of Credit, together with
                  interest as hereinafter provided.




                                       14
<PAGE>   19

                  (d) Reimbursement. In the event of any request for a drawing
         or any drawing under any Letter of Credit, the Issuing Lender will
         promptly notify the Borrowers. Unless a Borrower shall immediately
         notify the Issuing Lender of its intent to otherwise reimburse the
         Issuing Lender, the Borrower shall be deemed to have requested a Loan
         at the Base Rate in the amount of the drawing as provided in subsection
         (e) hereof, the proceeds of which will be used to satisfy the
         reimbursement obligations. The Borrower shall reimburse the Issuing
         Lender on the day of drawing under any Letter of Credit either with the
         proceeds of a Loan obtained hereunder or otherwise in same day funds as
         provided herein or in the LOC Documents. If the Borrower shall fail to
         reimburse the Issuing Lender as provided hereinabove, the unreimbursed
         amount of such drawing shall bear interest at a per annum rate equal to
         the Base Rate plus two percent (2%). The Borrowers' reimbursement
         obligations hereunder shall be absolute and unconditional under all
         circumstances irrespective of (but without waiver of) any rights of
         set-off, counterclaim or defense to payment that the applicable account
         party or the Borrowers may claim or have against the Issuing Lender,
         the Agent, the Lenders, the beneficiary of the Letter of Credit drawn
         upon or any other Person, including without limitation, any defense
         based on any failure of the applicable account party or the Borrowers
         to receive consideration or the legality, validity, regularity or
         unenforceability of the Letter of Credit. The Issuing Lender 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
         Issuing Lender, in Dollars and in immediately available funds, the
         amount of such Lender's Commitment Percentage of such unreimbursed
         drawing. Such payment shall be made on the day such notice is received
         by such Lender from the Issuing Lender if such notice is received at or
         before 2:00 p.m., otherwise such payment shall be made at or before
         12:00 Noon on the Business Day next succeeding the day such notice is
         received. If such Lender does not pay such amount to the Issuing Lender
         in full upon such request, such Lender shall, on demand, pay to the
         Agent for the account of the Issuing Lender interest on the unpaid
         amount during the period from the date the Lender received the notice
         regarding the unreimbursed drawing until such Lender pays such amount
         to the Issuing Lender in full at a rate per annum equal to, if paid
         within two Business Days of the date of drawing, the Federal Funds Rate
         and thereafter at a rate equal to the Base Rate. Each Lender's
         obligation to make such payment to the Issuing Lender, and the right of
         the Issuing Lender to receive the same, shall be absolute and
         unconditional, shall not be affected by any circumstance whatsoever and
         without regard to the termination of this Credit Agreement or the
         Commitments hereunder, the existence of a Default or Event of Default
         or the acceleration of the obligations hereunder and shall be made
         without any offset, abatement, withholding or reduction whatsoever.
         Simultaneously with the making of each such payment by a Lender to the
         Issuing Lender, such Lender shall, automatically and without any
         further action on the part of the Issuing Lender or such Lender,
         acquire a participation in an amount equal to such payment (excluding
         the portion of such payment constituting interest owing to the Issuing
         Lender) in the related unreimbursed drawing





                                       15
<PAGE>   20

         portion of the LOC Obligation and in the interest thereon and in the
         related LOC Documents, and shall have a claim against the Borrowers
         with respect thereto.

                  (e) Repayment with Loans. On any day on which a Borrower shall
         have requested, or been deemed to have requested, a Loan borrowing to
         reimburse a drawing under a Letter of Credit, the Agent shall give
         notice to the applicable Lenders that a Loan has been requested or
         deemed requested in connection with a drawing under a Letter of Credit,
         in which case a Loan borrowing comprised solely of Base Rate Loans
         (each such borrowing, a "Mandatory Borrowing") shall be immediately
         made from all applicable Lenders (without giving effect to any
         termination of the Commitments pursuant to Section 9.2 or otherwise)
         pro rata based on each Lender's respective Commitment Percentage and
         the proceeds thereof shall be paid directly to the Issuing Lender for
         application to the respective LOC Obligations. Each such Lender hereby
         irrevocably agrees to make such Loans immediately upon any such request
         or deemed request on account of each such Mandatory Borrowing in the
         amount and in the manner specified in the preceding sentence and on the
         same such date notwithstanding (i) the amount of Mandatory Borrowing
         may not comply with the minimum amount for borrowings of Loans
         otherwise required hereunder, (ii) whether any conditions specified in
         Section 5.2 are then satisfied, (iii) whether a Default or Event of
         Default then exists, (iv) failure of any such request or deemed request
         for Loans to be made by the time otherwise required hereunder, (v) the
         date of such Mandatory Borrowing, or (vi) any reduction in the
         Revolving Committed Amount or any termination of the Commitments. In
         the event that any Mandatory Borrowing cannot for any reason be made on
         the date otherwise required above (including, without limitation, as a
         result of the commencement of a proceeding under the Bankruptcy Code
         with respect to the Borrower), then each such Lender hereby agrees that
         it shall forthwith fund (as of the date the Mandatory Borrowing would
         otherwise have occurred, but adjusted for any payments received from
         the Borrower on or after such date and prior to such purchase) its
         Participation Interest in the outstanding LOC Obligations; provided,
         further, that in the event any Lender shall fail to fund its
         Participation Interest on the day the Mandatory Borrowing would
         otherwise have occurred, then the amount of such Lender's unfunded
         Participation Interest therein shall bear interest payable to the
         Issuing Lender upon demand, at the rate equal to, if paid within two
         Business Days of such date, the Federal Funds Rate, and thereafter at a
         rate equal to the Base Rate.

                  (f) Designation of Subsidiaries as Account Parties.
         Notwithstanding anything to the contrary set forth in this Credit
         Agreement, 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 of the Borrower; provided that notwithstanding such
         statement, the Borrower shall be the actual account party for all
         purposes of this Credit Agreement for such Letter of Credit and such
         statement shall not affect the Borrower's reimbursement obligations
         hereunder with respect to such Letter of Credit.

                  (g) Modification and Extension. The issuance of any
         supplement, modification, amendment, renewal, or extension to any
         Letter of Credit shall, for




                                       16
<PAGE>   21

         purposes hereof, be treated in all respects the same as the issuance of
         a new Letter of Credit hereunder.

                  (h) Uniform Customs and Practices. The Issuing Lender may have
         the Letters of Credit be subject to The Uniform Customs and Practice
         for Documentary Credits (the "UCP") or the International Standby
         Practices 1998 (the "ISP98"), in either case as published as of the
         date of issue by the International Chamber of Commerce, in which case
         the UCP or ISP98, as applicable, may be incorporated therein and deemed
         in all respects to be a part thereof.

                  (i) Responsibility of Issuing Lender. It is expressly
         understood and agreed that the obligations of the Issuing Lender
         hereunder to the Lenders are only those expressly set forth in this
         Credit Agreement and that the Issuing Lender shall be entitled to
         assume that the conditions precedent set forth in Section 5.2 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 Issuing Lender any amounts made
         available by such Lender to the Issuing Lender pursuant to this Section
         2.2 in the event that it is determined by a court of competent
         jurisdiction that the payment with respect to a Letter of Credit
         constituted gross negligence or willful misconduct on the part of the
         Issuing Lender.

                  (j) Conflict with LOC Documents. In the event of any conflict
         between this Credit Agreement and any LOC Document, this Credit
         Agreement shall govern.

                  (k) Indemnification of Issuing Lender.

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

                                    (ii) As between the Borrowers and the
                  Issuing Lender, the Borrowers shall assume all risks of the
                  acts, omissions or misuse of any Letter of Credit by the
                  beneficiary thereof. The Issuing Lender shall not be
                  responsible for: (A) 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) the validity or



                                       17
<PAGE>   22

                  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) failure of the beneficiary of a Letter of Credit
                  to comply fully with conditions required in order to draw upon
                  a Letter of Credit; (D) 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; (E) errors in interpretation of technical terms;
                  (F) 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 (G) any consequences
                  arising from causes beyond the control of the Issuing Lender,
                  including, without limitation, any Government Acts. None of
                  the above shall affect, impair, or prevent the vesting of the
                  Issuing Lender's rights or powers hereunder.

                                    (iii) In furtherance and extension and not
                  in limitation of the specific provisions hereinabove set
                  forth, any action taken or omitted by the Issuing Lender,
                  under or in connection with any Letter of Credit or the
                  related certificates, if taken or omitted in good faith, shall
                  not put the Issuing Lender under any resulting liability to
                  the Borrowers. It is the intention of the parties that this
                  Credit Agreement shall be construed and applied to protect and
                  indemnify the Issuing Lender against any and all risks
                  involved in the issuance of the Letters of Credit, all of
                  which risks are hereby assumed by the Borrowers, including,
                  without limitation, any and all risks of the acts or
                  omissions, whether rightful or wrongful, of any present or
                  future Government Acts. The Issuing Lender shall not, in any
                  way, be liable for any failure by the Issuing Lender or anyone
                  else to pay any drawing under any Letter of Credit as a result
                  of any Government Acts or any other cause beyond the control
                  of the Issuing Lender.

                                    (iv) Nothing in this subsection (k) is
                  intended to limit the reimbursement obligation of the
                  Borrowers contained in this Section 2.2. The obligations of
                  the Borrowers under this subsection (k) shall survive the
                  termination of this Credit Agreement. No act or omission of
                  any current or prior beneficiary of a Letter of Credit shall
                  in any way affect or impair the rights of the Issuing Lender
                  to enforce any right, power or benefit under this Credit
                  Agreement.

                                    (v) Notwithstanding anything to the contrary
                  contained in this subsection (k) or any of the Credit
                  Documents, the Borrower shall have no obligation to indemnify
                  the Issuing Lender in respect of any liability incurred by the
                  Issuing Lender arising solely out of the negligence or willful
                  misconduct of the Issuing Lender, as determined by a court of
                  competent jurisdiction. Nothing in this Credit Agreement shall
                  relieve the Issuing Lender of any liability to the Borrower in
                  respect of any action taken by the Issuing Lender which action
                  constitutes negligence or willful misconduct of the Issuing
                  Lender or a violation

                  of the UCP, the ISP98 or Uniform Commercial Code (as
                  applicable), as determined by a court of competent
                  jurisdiction.

         2.3 METHOD OF BORROWING FOR LOANS.

         By no later than 11:00 a.m. (a) on the date of the requested borrowing
of Loans that will be Base Rate Loans or (b) three Business Days prior to the
date of the requested borrowing of Loans that will be Eurodollar Loans, the
Borrowers shall submit a written Notice of Borrowing in the form of Exhibit 2.3
to the Agent setting forth (i) the amount requested, (ii) whether such Loans
shall accrue interest at the Base Rate or the Adjusted Eurodollar Rate, (iii)
with respect to Loans that will be Eurodollar Loans, the Interest Period
applicable thereto and (iv) certification that the Borrowers have complied in
all respects with Section 5.2.

         2.4 FUNDING OF LOANS.

         Upon receipt of a Notice of Borrowing, the Agent shall promptly inform
the Lenders as to the terms thereof. Each such Lender shall make its Commitment
Percentage of the requested Loans available to the Agent by 2:00 p.m. on the
date specified in the Notice of Borrowing by deposit, in Dollars, of immediately
available funds at the Agency Services Address. The amount of the requested
Loans will then be made available to the Borrowers by the Agent by crediting the
account of the Borrowers on the books of such office of the Agent, to the extent
the amount of such Loans are made available to the Agent.

         No Lender shall be responsible for the failure or delay by any other
Lender in its obligation to make Loans hereunder; provided, however, that the
failure of any Lender to fulfill its obligations hereunder shall not relieve any
other Lender of its obligations hereunder. Unless the Agent shall have been
notified by any Lender prior to the date of any such Loan that such Lender does
not intend to make available to the Agent its portion of the Loans to be made on
such date, the Agent may assume that such Lender has made such amount available
to the Agent on the date of such Loans, and the Agent in reliance upon such
assumption, may (in its sole discretion but without any obligation to do so)
make available to the Borrowers a corresponding amount. If such corresponding
amount is not in fact made available to the Agent, the Agent shall be able to
recover such corresponding amount from such Lender. If such Lender does not pay
such corresponding amount forthwith upon the Agent's demand therefor, the Agent
will promptly notify the Borrowers and the Borrowers shall immediately pay such
corresponding amount within two Business Days to the Agent. The Agent shall also
be entitled to recover from the Lender or the Borrowers, as the case may be,
interest on such corresponding amount in respect of each day from the date such
corresponding amount was made available by the Agent to the Borrowers to the
date such corresponding amount is recovered by the Agent at a per annum rate
equal to (a) from the Borrowers at the applicable rate for such Loan pursuant to
the Notice of Borrowing and (b) from a Lender at the Federal Funds Rate.

         2.5 CONTINUATIONS AND CONVERSIONS.

         The Borrowers shall have the option (subject to the limitations set
forth below), on any Business Day, to continue existing Eurodollar Loans for a
subsequent Interest Period, to convert Base Rate Loans into Eurodollar Loans or
to convert Eurodollar Loans into Base Rate Loans; provided, however, that (a)
each such continuation or conversion must be requested by the Borrowers pursuant
to a written Notice of Continuation/Conversion, in the form of Exhibit 2.5, in
compliance with the terms set forth below, (b) if a Eurodollar Loan is continued
or converted into a Base Rate Loan on any day other than the last day of the
Interest Period applicable thereto, then the Borrowers shall be subject to the
provisions set forth in Section 4.3, (c) Eurodollar Loans may not be continued
nor may Base Rate Loans be converted into Eurodollar Loans during the existence
and continuation of a Default or Event of Default and (d) any request to extend
a Eurodollar Loan that fails to comply with the terms hereof or any failure to
request an extension of a Eurodollar Loan at the end of an Interest Period shall
constitute a conversion to a Base Rate Loan on the last day of the applicable
Interest Period. Each continuation or conversion must be requested by the
Borrowers no later than 11:00 a.m. (i) on the date for a requested conversion of
a Eurodollar Loan to a Base Rate Loan or (ii) three Business Days prior to the
date for a requested continuation of a Eurodollar Loan or conversion of a Base
Rate Loan to a Eurodollar Loan, in each case pursuant to a written Notice of
Continuation/Conversion submitted to the Agent which shall set forth (A) whether
the Borrowers wish to continue or convert such Loans and (B) if the request is
to continue a Eurodollar Loan or convert a Base Rate Loan to a Eurodollar Loan,
the Interest Period applicable thereto.

         2.6 MINIMUM AMOUNTS.

         Each request for a Loan or a conversion or continuation hereunder shall
be subject to the following requirements: (a) each Eurodollar Loan shall be in a
minimum amount of $10,000,000 (and in integral multiples of $1,000,000 in excess
thereof), (b) each Base Rate Loan shall be in a minimum amount of the lesser of
$10,000,000 (and in integral multiples of $1,000,000 in excess thereof) or the
remaining amount available to be borrowed and (c) no more than ten Eurodollar
Loans shall be outstanding hereunder at any one time. For the purposes of this
Section, all Eurodollar Loans with the same Interest Periods that begin and end
on the same date shall be considered as one Eurodollar Loan, but Eurodollar
Loans with different Interest Periods, even if they begin on the same date,
shall be considered separate Eurodollar Loans.

         2.7 REDUCTIONS OF REVOLVING COMMITTED AMOUNTS.

         Upon at least five Business Days' notice, the Borrowers shall have the
right to permanently terminate or reduce the aggregate unused amount of the
Revolving Committed Amount at any time or from time to time; provided that (a)
each partial reduction shall be in an aggregate amount at least equal to
$10,000,000 and in integral multiples of $1,000,000 above such amount, (b) no
reduction shall be made which would reduce the Revolving Committed Amount to an
amount less than the aggregate amount of the then outstanding Loans plus the
aggregate amount of the then outstanding LOC Obligations. Any reduction in (or
termination of) the Revolving Committed Amount shall be permanent and may not be
reinstated.

         2.8 NOTES.

         The Loans made by the Lenders shall be evidenced by a duly executed
promissory note of the Borrowers payable to each Lender in substantially the
form of Exhibit 2.8 (the "Notes").

         2.9 JOINT AND SEVERAL LIABILITY OF THE BORROWERS.

         Subject to Section 2.10:

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

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

                  (c) If and to the extent that either of the Borrowers shall
         fail to make any payment with respect to any of the obligations
         hereunder as and when due or to perform any of such obligations in
         accordance with the terms thereof, then in each such event, the other
         Borrower will make such payment with respect to, or perform, such
         obligation.

                  (d) The provisions of this Section 2.9 are made for the
         benefit of the Lenders and their successors and assigns, and may be
         enforced by them from time to time against either of the Borrowers as
         often as occasion therefor may arise and without requirement on the
         part of the Lenders first to marshall any of its claims or to exercise
         any of its rights against the other Borrower or to exhaust any remedies
         available to it against the other Borrower or to resort to any other
         source or means of obtaining payment of any of the Borrowers
         Obligations hereunder or to elect any other remedy. The provisions of
         this Section 2.9 shall remain in effect until all the Borrowers
         Obligations hereunder shall have been paid in full or otherwise fully
         satisfied. If at any time, any payment, or any part thereof, made in
         respect of any of the Borrowers Obligations, is rescinded or must
         otherwise be restored or returned by the Lenders upon the insolvency,
         bankruptcy or reorganization of any of the Borrowers, or otherwise, the
         provisions of this Section 2.9 will forthwith be reinstated and in
         effect as though such payment had not been made.

                  (e) Notwithstanding any provision to the contrary contained
         herein or in any of the other Credit Documents, to the extent the
         obligations of either Borrower shall be






                                       21
<PAGE>   26

         adjudicated to be invalid or unenforceable for any reason (including,
         without limitation, because of any applicable state or federal law
         relating to fraudulent conveyances or transfers) then the obligations
         of such Borrower hereunder shall be limited to the maximum amount that
         is permissible under applicable law (whether federal or state and
         including, without limitation, the Bankruptcy Code).

                  (f) Each Borrower hereby appoints the other Borrower to act as
         its agent for all purposes under this Credit Agreement (including,
         without limitation, with respect to all matters relating to the
         borrowing and repayment of Loans) and agrees that (i) a Borrower may
         execute such documents on behalf of the other Borrower as it deems
         appropriate and the other Borrower shall be obligated by all of the
         terms of any such document executed on its behalf, (ii) any notice or
         communication delivered by the Agent or a Lender to a Borrower shall be
         deemed delivered to both Borrowers and (iii) the Agent and the Lenders
         may accept, and be permitted to rely on, any document, instrument or
         agreement executed by one Borrower on behalf of the other Borrower.

         2.10 LIMITATION OF LIABILITY OF BORROWERS.

         Notwithstanding anything in this Credit Agreement or in the Notes to
the contrary, including without limitation, Section 2.9:

                  (a) Duke Energy Field Services Corporation shall have no
         rights or obligations as a Borrower, and will not be subject to the
         terms of the Credit Documents, until (i) consummation of the Merger or
         a Corporate Conversion and (ii) notification from the Borrowers to the
         Lenders that the Merger or a Corporate Conversion has occurred and
         that, going forward, Duke Energy Field Services Corporation will
         irrevocably have all of the rights and obligations of a Borrower,
         jointly and severally with Duke Energy Field Services, LLC, under the
         Credit Documents (including, without limitation, any Loans made prior
         to such notification) and will be subject to the terms of the Credit
         Documents.

                  (b) If the Merger occurs, the agreement by Duke Energy Field
         Services Corporation to become jointly and severally liable with Duke
         Energy Field Services, LLC for the indebtedness under the Credit
         Documents pursuant to subsection (a) above shall be accomplished in two
         phases: (i) initially, Duke Energy Field Services Corporation shall
         become directly liable for 69.7% of such indebtedness and shall become
         indirectly liable for 30.3% of such indebtedness through Phillips Gas
         Company ("PGC"), a Delaware corporation and, subsequent to the first
         step of the Merger, a wholly-owned Subsidiary of Duke Energy Field
         Services Corporation, in each case jointly and severally with Duke
         Energy Field Services, LLC, which shall remain jointly and severally
         liable for 100% of such indebtedness; and (ii) immediately thereafter,
         upon the merger of PGC with and into Duke Energy Field Services
         Corporation, Duke Energy Field Services Corporation shall become
         directly liable for the 30.3% of such indebtedness previously
         attributed to it through its ownership of PGC.




                                       22
<PAGE>   27

                  (c) On or after the date that, pursuant to subsection (a) or
         subsections (a) and (b) above, Duke Energy Field Services Corporation
         has become directly liable for 100% of the indebtedness, rights and
         obligations of a Borrower under the Credit Documents, the Borrowers
         may, upon written notice to the Lenders, release Duke Energy Field
         Services, LLC from its joint and several obligations under the Credit
         Documents; provided that if as a result of a Corporate Conversion Duke
         Energy Field Services LLC is converted into a "C" Corporation it shall
         not be released from its obligations hereunder. Thereafter, Duke Energy
         Field Services, LLC will have no rights or obligations under the Credit
         Documents, will no longer be subject to the terms of the Credit
         Documents (except as the terms thereof may relate to it if it
         constitutes a Material Subsidiary) and all obligations owing pursuant
         to the Credit Documents shall be the sole responsibility of Duke Energy
         Field Services Corporation.

                  (d) Notwithstanding the use of the term "Borrowers" as set
         forth in the Credit Documents: (i) prior to Duke Energy Field Services
         Corporation having any rights or obligations as a Borrower, as set
         forth in clause (a) above, the terms "Borrowers" or "a Borrower" as
         used in the Credit Documents shall only mean a reference to Duke Energy
         Field Services, LLC and (ii) on and after the date that Duke Energy
         Field Services, LLC is released from liability, in accordance with
         clause (c) above, the terms "Borrowers" or "a Borrower" as used in the
         Credit Documents shall only mean a reference to Duke Energy Field
         Services Corporation.


                                   SECTION 3.

                                    PAYMENTS

         3.1 INTEREST.

                  (a) Interest Rate.

                           (i) All Base Rate Loans shall accrue interest at the
                  Base Rate.

                           (ii) All Eurodollar Loans shall accrue interest at
                  the Adjusted Eurodollar Rate applicable to such Eurodollar
                  Loan.

                  (b) Default Rate of Interest. Upon the occurrence, and during
         the continuation, of an Event of Default, all past due principal of
         and, to the extent permitted by law, past due interest on, the Loans
         and any other past due amounts owing hereunder or under the other
         Credit Documents shall bear interest, payable on demand, at a per annum
         rate equal to one percent (1%) plus the rate which would otherwise be
         applicable (or if no rate is applicable, then the rate for Loans that
         are Base Rate Loans plus one percent (1%) per annum).

                  (c) Interest Payments. Interest on Loans shall be due and
         payable in arrears on each Interest Payment Date.

         3.2 PREPAYMENTS.

                  (a) Voluntary Prepayments. The Borrowers shall have the right
         to prepay Loans in whole or in part from time to time without premium
         or penalty; provided, however, that (i) Eurodollar Loans may only be
         prepaid on three Business Days' prior written notice to the Agent and
         any prepayment of Eurodollar Loans will be subject to Section 4.3; and
         (ii) each such partial prepayment of Loans shall be in the minimum
         principal amount of $10,000,000. Any payments made under this Section
         3.2(a) shall be applied as the Borrowers may elect; provided that if
         the Borrowers fail to specify how a voluntary prepayment should be
         applied then such prepayment shall be applied first to Base Rate Loans
         and then to Eurodollar Loans in direct order of Interest Period
         maturities.

                  (b) Mandatory Prepayments. If at any time (A) the amount of
         Loans outstanding plus the aggregate amount of LOC Obligations
         outstanding exceeds the Revolving Committed Amount or (B) the aggregate
         amount of LOC Obligations outstanding exceeds the LOC Committed Amount,
         the Borrowers shall immediately make a principal payment to the Agent
         in a manner and in an amount necessary to be in compliance with
         Sections 2.1 and 2.2, as applicable, and as directed by the Agent. All
         amounts required to be paid pursuant to this Section 3.2(b) shall be
         (i) applied first to Loans and then to a cash collateral account in
         respect of LOC Obligations, (ii) subject to Section 4.3 and (iii)
         applied first to Base Rate Loans and then to Eurodollar Loans in the
         direct order of Interest Period maturities.

         3.3 PAYMENT IN FULL AT MATURITY.

                  (a) Subject to Section 3.3(b) below, on the Maturity Date, the
         entire outstanding principal balance of all Loans and all LOC
         Obligations, together with accrued but unpaid interest and all other
         sums owing under this Credit Agreement, shall be due and payable in
         full, unless accelerated sooner pursuant to Section 9.2.

                  (b) On or before ten Business Days prior to the Maturity Date,
         the Borrower may, as long as no Default or Event of Default exists and
         is continuing, notify the Agent in writing (and the Agent shall
         promptly forward such notice to the Lenders) that, as of the Maturity
         Date, it is converting the outstanding Loans to a term loan which shall
         be due and payable in full on the date one year subsequent to the
         Maturity Date (the "Term Out Maturity Date"). It is understood and
         agreed that subsequent to the Maturity Date, (i) the Borrowers may no
         longer request, and the Lenders are no longer obligated to make or
         issue, new Loans or Letters of Credit, (ii) any amounts repaid may not
         be reborrowed, (iii) interest shall accrue on the outstanding Loans, at
         the option of the Borrowers, in accordance with the terms of Section
         2.5 and (iv) the Borrowers shall have the right to prepay all or a
         portion of the outstanding Loans in accordance with Section 3.2(a).

         3.4 FEES.

                  (a) Commitment Fees. In consideration of the Revolving
         Committed Amount being made available by the Lenders, the Borrowers
         agree to pay to the Agent, for the pro rata benefit of each Lender, a
         fee equal to the Applicable Margin for Commitment Fees on the Unused
         Commitment (the "Commitment Fees"). The accrued Commitment Fees shall
         be due and payable in arrears on the first Business Day after the end
         of each fiscal quarter of the Borrowers (as well as on the Maturity
         Date) for the immediately preceding fiscal quarter (or portion
         thereof), beginning with the first of such dates to occur after the
         Closing Date.

                  (b) Utilization Fees. If, on any day, the sum of the aggregate
         outstanding principal amount of all Loans plus the outstanding amount
         of LOC Obligations exceeds the product of (A) one-third (1/3) times (B)
         the Revolving Committed Amount, the Borrowers agree to pay to the
         Agent, for the pro rata benefit of each Lender, a per annum fee equal
         to the Applicable Margin for Utilization Fees on the Utilized Revolving
         Committed Amount (the "Utilization Fees"). The accrued Utilization
         Fees, if any, shall be due and payable in arrears on the first Business
         Day after the end of each fiscal quarter of the Borrowers (as well as
         on the Maturity Date and the Term Out Maturity Date, if applicable) for
         the immediately preceding fiscal quarter (or portion thereof),
         beginning with the first of such dates to occur after the Closing Date.

                  (c) Letter of Credit Fees.

                           (i) Letter of Credit Fees. In consideration of the
                  issuance of Letters of Credit hereunder, the Borrowers agree
                  to pay to the Issuing Lender, for the pro rata benefit of each
                  Lender, a per annum fee equal to the Applicable Margin for
                  Eurodollar Loans prior to Maturity on the aggregate stated
                  amount for each Letter of Credit from the date of issuance to
                  the date of expiration (the "Letter of Credit Fees"). The
                  accrued Letter of Credit Fees shall be due and payable in
                  arrears on the first Business Day after the end of each fiscal
                  quarter of the Borrowers (as well as on the Maturity Date) for
                  the immediately preceding fiscal quarter (or portion thereof),
                  beginning with the first of such dates to occur after the
                  Closing Date.

                           (ii) Issuing Lender Fees. In addition to the Letter
                  of Credit Fees payable pursuant to subsection (i) above, the
                  Borrowers shall pay to the Issuing Lender for its own account,
                  without sharing by the other Lenders, (A) a fee equal to
                  one-eighth of one percent (.125%) per annum on the total sum
                  of all Letters of Credit issued by the Issuing Lender, such
                  fee to be paid on the date of issuance of any Letter of Credit
                  and (B) the customary charges from time to time to the Issuing
                  Lender for its services in connection with the issuance,
                  amendment, payment, transfer, administration, cancellation and
                  conversion of, and drawings under, such Letters of Credit
                  (collectively, the "Issuing Lender Fees").

         3.5 PLACE AND MANNER OF PAYMENTS.

         All payments of principal, interest, fees, expenses and other amounts
to be made by a Borrower under this Credit Agreement shall be made without
setoff, deduction or counterclaim and received not later than 2:00 p.m. on the
date when due in Dollars and in immediately available funds by the Agent at the
Agency Services Address. A Borrower shall, at the time it makes any payment
under this Credit Agreement, specify to the Agent the Loans, Letters of Credit,
fees or other amounts payable by a Borrower hereunder to which such payment is
to be applied (and in the event that it fails 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 it reasonably determines in its sole
discretion). The Agent will distribute such payments to the applicable Lenders
on the same Business Day if any such payment is received prior to 2:00 p.m.;
otherwise the Agent will distribute each payment to the applicable Lenders prior
to 12:00 noon on the next succeeding Business Day. Whenever any payment
hereunder shall be stated to be due on a day which is not a Business Day, the
due date thereof shall be extended to the next succeeding Business Day (subject
to accrual of interest and fees for the period of such extension), except that
in the case of Eurodollar Loans, if the extension would cause the payment to be
made in the next following calendar month, then such payment shall be made on
the next preceding Business Day.

         3.6 PRO RATA TREATMENT.

         (a) Loans. Except to the extent otherwise provided herein, all Loans,
each payment or prepayment of principal of any Loan, each payment of interest on
the Loans, each payment of Commitment Fees, each payment of Utilization Fees,
each payment of Letter of Credit Fees, each reduction of the Revolving Committed
Amount and each conversion or continuation of any Loans, shall be allocated pro
rata among the applicable Lenders in accordance with their respective Commitment
Percentages; provided that, if any Lender shall have failed to pay its
applicable pro rata share of any Loan, then any amount to which such Lender
would otherwise be entitled pursuant to this Section 3.6 shall instead be
payable to the Agent until the share of such Loan not funded by such Lender has
been repaid and any interest owed by such Lender as result of such failure to
fund has been paid; and provided further, that in the event any amount paid to
any Lender pursuant to this Section 3.6 is rescinded or must otherwise be
returned by the Agent, each Lender shall, upon the written request of the Agent,
repay to the Agent the amount so paid to such Lender, with interest for the
period commencing on the date such payment is returned by the Agent until the
date the Agent receives such repayment at a rate per annum equal to, during the
period to but excluding the date two Business Days after such request, the
Federal Funds Rate, and thereafter, the Base Rate plus one percent (1%) per
annum.

         (b) Letters of Credit. Each payment of unreimbursed drawings in respect
of LOC Obligations shall be allocated to each Lender pro rata in accordance with
its Commitment Percentage; provided that, if any Lender shall have failed to pay
its applicable pro rata share of any drawing under any Letter of Credit, then
any amount to which such Lender would otherwise be entitled pursuant to this
subsection (b) shall instead be payable to the Issuing Lender; provided further,
that in the event any amount paid to any Lender pursuant to this subsection (b)
is rescinded or must otherwise be returned by the Issuing Lender, each Lender
shall, upon the





                                       26
<PAGE>   31

written request of the Issuing Lender, repay to the Agent for the account of the
Issuing Lender the amount so paid to such Lender, with interest for the period
commencing on the date such payment is returned by the Issuing Lender until the
date the Issuing Lender receives such repayment at a rate per annum equal to,
during the period to but excluding the date two Business Days after such
request, the Federal Funds Rate, and thereafter, the Base Rate plus one percent
(1%) per annum.

         3.7 COMPUTATIONS OF INTEREST AND FEES.

                  (a) Except for Base Rate Loans that are based upon the Prime
         Rate, on which interest shall be computed on the basis of a 365 or 366
         day year as the case may be, all computations of interest and fees
         hereunder shall be made on the basis of the actual number of days
         elapsed over a year of 360 days.

                  (b) It is the intent of the Lenders and the Borrowers to
         conform to and contract in strict compliance with applicable usury law
         from time to time in effect. All agreements between the Lenders and the
         Borrowers are hereby limited by the provisions of this paragraph which
         shall override and control all such agreements, whether now existing or
         hereafter arising and whether written or oral. In no way, nor in any
         event or contingency (including but not limited to prepayment or
         acceleration of the maturity of any obligation), shall the interest
         taken, reserved, contracted for, charged, or received under this Credit
         Agreement, under the Notes or otherwise, exceed the maximum nonusurious
         amount permissible under applicable law. If, from any possible
         construction of any of the Credit Documents or any other document,
         interest would otherwise be payable in excess of the maximum
         nonusurious amount, any such construction shall be subject to the
         provisions of this paragraph and interest owing pursuant to such
         documents shall be automatically reduced to the maximum nonusurious
         amount permitted under applicable law, without the necessity of
         execution of any amendment or new document. If any Lender shall ever
         receive anything of value which is characterized as interest on the
         Loans under applicable law and which would, apart from this provision,
         be in excess of the maximum lawful amount, an amount equal to the
         amount which would have been excessive interest shall, without penalty,
         be applied to the reduction of the principal amount owing on the Loans
         and not to the payment of interest, or refunded to the Borrowers or the
         other payor thereof if and to the extent such amount which would have
         been excessive exceeds such unpaid principal amount of the Loans. The
         right to demand payment of the Loans or any other indebtedness
         evidenced by any of the Credit Documents does not include the right to
         receive any interest which has not otherwise accrued on the date of
         such demand, and the Lenders do not intend to charge or receive any
         unearned interest in the event of such demand. All interest paid or
         agreed to be paid to the Lenders with respect to the Loans shall, to
         the extent permitted by applicable law, be amortized, prorated,
         allocated, and spread throughout the full stated term (including any
         renewal or extension) of the Loans so that the amount of interest on
         account of such indebtedness does not exceed the maximum nonusurious
         amount permitted by applicable law.

         3.8 SHARING OF PAYMENTS.

                  Each Lender agrees that, in the event that any Lender shall
         obtain payment in respect of any Loan, any unreimbursed drawing with
         respect to any LOC Obligations or any other obligation owing to such
         Lender under this Credit Agreement through the exercise of a right of
         set-off, banker's lien, counterclaim or otherwise (including, but not
         limited to, pursuant to the Bankruptcy Code) in excess of its pro rata
         share as provided for in this Credit Agreement, such Lender shall
         promptly purchase from the other Lenders a participation in such Loans,
         LOC Obligations and other obligations, in such amounts and with such
         other adjustments from time to time, as shall be equitable in order
         that all Lenders share such payment in accordance with their respective
         ratable shares as provided for in this Credit Agreement. Each Lender
         further agrees that if a payment to a Lender (which is obtained by such
         Lender through the exercise of a right of set-off, banker's lien,
         counterclaim or otherwise) 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 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 set-off,
         banker's lien or counterclaim, with respect to such participation as
         fully as if such Lender were a holder of such Loan or other obligation
         in the amount of such participation. Except as otherwise expressly
         provided in this Credit Agreement, if any Lender shall fail to remit to
         the Agent or any other Lender an amount payable by such Lender to the
         Agent or such other Lender pursuant to this Credit Agreement on the
         date when such amount is due, such payments shall accrue interest
         thereon, for each day from the date such amount is due until the day
         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 3.8 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 3.8 to share in the benefits of any
         recovery on such secured claim.

         3.9 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.

                  (b) The Agent shall maintain the Register pursuant to Section
         11.3(c), and a subaccount for each Lender, in which Register and
         subaccounts (taken together) shall be recorded (i) the amount, type and
         Interest Period of each such Loan hereunder, (ii) the amount of any
         principal or interest due and payable or to become due and payable to
         each Lender hereunder and (iii) the amount of any sum received by the
         Agent hereunder from






                                       28
<PAGE>   33

         or for the account of the Borrowers 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 Register and subaccounts
         maintained pursuant to subsection (b) of this Section 3.9, and the
         entries made in the accounts maintained pursuant to subsection (a) of
         this Section 3.9, if consistent with the entries of the Agent, 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.


                                   SECTION 4.

                      ADDITIONAL PROVISIONS REGARDING LOANS

         4.1 EURODOLLAR LOAN PROVISIONS.

                  (a) Unavailability. If, on or prior to the first day of any
         Interest Period, (i) the Agent shall have determined in good faith
         (which determination shall be conclusive and binding upon the
         Borrowers) that (A) Dollar deposits are not generally available in the
         London interbank Eurodollar market in the applicable principal amounts
         and Interest Period of a requested Eurodollar Loan or (B) by reason of
         circumstances affecting the relevant market, adequate and reasonable
         means do not exist for ascertaining the Eurodollar Rate for such
         Interest Period, or (ii) the Agent shall have received notice from the
         Required Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to the Lenders of making or maintaining Eurodollar
         Loans for such Interest Period (as conclusively certified by such
         Lenders), the Agent shall give notice thereof to the Borrowers and the
         Lenders as soon as practicable thereafter. Upon delivery of such
         notice, (A) any Eurodollar Loans requested to be made on the first day
         of such Interest Period shall be made as Base Rate Loans, (B) any Loans
         that were to have been converted to or continued as Eurodollar Loans
         shall be prepaid by the Borrowers or converted to or continued as Base
         Rate Loans and (C) any outstanding Eurodollar Loans shall be converted,
         on the first day of such Interest Period, to Base Rate Loans. Until the
         Agent has withdrawn such notice, 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.

                  (b) Change in Legality. Notwithstanding any other provision
         herein, if any change, after the date hereof, in any law, governmental
         rule, regulation, guideline or order (including the introduction of any
         new law or governmental rule, regulation, guideline or order) or in the
         interpretation or administration thereof by any Governmental Authority



                                       29
<PAGE>   34

         charged with the interpretation or administration thereof shall make it
         unlawful for any Lender to make or maintain any Eurodollar Loan then,
         by written notice to the Borrowers and to the Agent, such Lender may:

                           (i) declare that Eurodollar Loans and conversions to
                  or continuations of Eurodollar Loans, will not thereafter be
                  made by such Lender hereunder, whereupon any request by the
                  Borrowers for, or for conversion into or continuation of,
                  Eurodollar Loans shall, as to such Lender only, be deemed a
                  request for, or for conversion into or continuation of, Base
                  Rate Loans, unless such declaration shall be subsequently
                  withdrawn; and

                           (ii) require that all outstanding Eurodollar Loans
                  made by it be converted to Base Rate Loans in which event all
                  such Eurodollar Loans shall be converted to Base Rate Loans
                  either (A) on the last day of the then current Interest Period
                  applicable to such Eurodollar Loan if such Lender can lawfully
                  continue to maintain and fund such Eurodollar Loan or (B)
                  immediately if such Lender shall determine that it may not
                  lawfully continue to maintain and fund such Eurodollar Loan to
                  such day.

                  (c) Requirements of Law. If at any time a Lender shall incur
         increased costs or reductions in the amounts received or receivable
         hereunder with respect to the making, the commitment to make or the
         maintaining of any Eurodollar Loan because of (i) any change after the
         date hereof in any law, governmental rule, regulation, guideline or
         order (including the introduction of any new law or governmental rule,
         regulation, guideline or order) or in the interpretation or
         administration thereof by any Governmental Authority charged with the
         interpretation or administration thereof, including, without
         limitation, the imposition, modification or deemed applicability of any
         reserves, deposits or similar requirements (such as, for example, but
         not limited to, a change in official reserve requirements) or (ii)
         other circumstances affecting the London interbank Eurodollar market;
         then the Borrowers shall pay to such Lender promptly upon written
         demand therefor, such additional amounts (in the form of an increased
         rate of, or a different method of calculating, interest or otherwise as
         such Lender may determine in its sole discretion) as may be required to
         compensate such Lender for such increased costs or reductions in
         amounts receivable hereunder. If any Lender becomes entitled to claim
         any additional amounts pursuant to this Section 4.1(c), it shall
         provide prompt notice thereof to the Borrowers, through the Agent,
         certifying (A) that one of the events described in this Section 4.1(c)
         has occurred and describing in reasonable detail the nature of such
         event, (B) as to the increased cost or reduced amount resulting from
         such event and (C) as to the additional amount demanded by such Lender
         and a reasonably detailed explanation of the calculation thereof
         provided that no such amount shall be payable with respect to any
         period commencing more than 90 days prior to the date such Lender first
         notifies the Borrowers of its intention to demand compensation therefor
         under this Section.

                  (d) Regulation D Compensation. In the event that a Lender is
         required to maintain reserves of the type contemplated by the
         definition of "Eurodollar Reserve







                                       30
<PAGE>   35

         Percentage", such Lender may require the Borrowers to pay,
         contemporaneously with each payment of interest on the Eurodollar
         Loans, additional interest on the related Eurodollar Loan of such
         Lender at a rate per annum determined by such Lender up to but not
         exceeding the excess of (i)(A) the applicable London Interbank Offered
         Rate divided by (B) one minus the Eurodollar Reserve Percentage over
         (ii) the applicable London Interbank Offered Rate. Any Lender wishing
         to require payment of such additional interest (x) shall so notify the
         Borrowers and the Agent, in which case such additional interest on the
         Eurodollar Loans of such Lender shall be payable to such Lender at the
         place indicated in such notice with respect to each Interest Period
         commencing at least three Business Days after the giving of such notice
         and (y) shall notify the Borrowers at least three Business Days prior
         to each date on which interest is payable on the Eurodollar Loans of
         the amount then due it under this Section. Each such notification shall
         be accompanied by such information as the Borrowers may reasonably
         request.

         Each determination and calculation made by a Lender under this Section
4.1 shall, absent manifest error, be binding and conclusive on the parties
hereto. Any conversions of Eurodollar Loans made pursuant to this Section 4.1
shall subject the Borrowers to the payments required by Section 4.3 to the
extent applicable. This Section shall survive termination of this Credit
Agreement and the other Credit Documents and payment of the Loans and all other
amounts payable hereunder.

         4.2 CAPITAL ADEQUACY.

         If any Lender has determined that the adoption or becoming effective,
after the date hereof, of any applicable law, rule or regulation regarding
capital adequacy, or any change therein (after the date hereof), or any change
in the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender (or its parent corporation)
with any request or directive regarding capital adequacy (whether or not having
the force of law) of any such Governmental Authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on such
Lender's (or parent corporation's) capital or assets as a consequence of its
commitments or obligations hereunder to a level below that which such Lender (or
its parent corporation) could have achieved but for such adoption,
effectiveness, change or compliance (taking into consideration such Lender's (or
parent corporation's) policies with respect to capital adequacy), then, upon
notice from such Lender (which shall include the basis and calculations in
reasonable detail supporting the compensation requested in such notice), and
receipt by the Borrowers of such written notice from such Lender (with a copy to
the Agent) the Borrowers shall be obligated to pay to such Lender such
additional amount or amounts as will compensate such Lender on an after tax
basis (after taking into account applicable deductions and credits in respect of
the amount so indemnified) for such reduction provided that no such amount shall
be payable with respect to any period commencing more than 90 days prior to the
date such Lender first notifies the Borrowers of its intention to demand
compensation therefor under this Section. Each determination by any Lender of
amounts owing under this Section 4.2 shall, absent manifest error, be conclusive
and binding on the parties hereto. The covenants of this Section 4.2 shall
survive termination of this Credit Agreement and the other Credit Documents and
the payment of the Loans and all other amounts payable hereunder.

         4.3 COMPENSATION.

         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 as a
consequence of (a) default by the Borrowers in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrowers have given a notice
requesting the same in accordance with the provisions of this Credit Agreement,
(b) default by the Borrowers in making any prepayment of a Eurodollar Loan after
the Borrowers have given a notice thereof in accordance with the provisions of
this Credit Agreement, (c) the making of a prepayment of Eurodollar Loans on a
day which is not the last day of an Interest Period with respect thereto and (d)
the payment, continuation or conversion of a Eurodollar Loan on a day which is
not the last day of the Interest Period applicable thereto or the failure to
repay a Eurodollar Loan when required by the terms of this Credit Agreement.
Such indemnification may include an amount equal to (i) an amount of interest
calculated at the Eurodollar Rate which would have accrued on the amount in
question, for the period from the date of such prepayment or of such failure to
borrow, convert, continue or repay 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 minus (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
Eurocurrency market. If any Lender becomes entitled to claim any additional
amounts pursuant to this Section 4.3, it shall provide prompt notice thereof to
the Borrower, through the Agent, as to the additional amount demanded by such
Lender and a reasonably detailed explanation of the calculation thereof. The
covenants in this Section 4.3 shall survive the termination of this Credit
Agreement and the payment of the Loans and all other amounts payable hereunder.

         4.4 TAXES.

                  (a) Except as provided below in this Section 4.4, 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: (i) by the jurisdiction under the laws of which 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




                                       32
<PAGE>   37

         such Lender having executed, delivered or performed its obligations, or
         received payment under or enforced, this Credit Agreement or any Notes.
         If any such non-excluded taxes, levies, imposts, duties, charges, fees,
         deductions or withholdings ("Non-Excluded Taxes") are required to be
         withheld from any amounts payable to an 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 Section 4.4
         whenever any Non-Excluded Taxes are payable by the Borrowers, and (B)
         as promptly as possible after requested, the Borrowers shall send to
         the Agent for its own account or for the account of such Lender, as the
         case may be, a certified copy of an original official receipt received
         by the Borrowers showing payment thereof. If the Borrowers fail to pay
         any Non-Excluded Taxes when due to the appropriate taxing authority or
         fails to remit to the Agent the required receipts or other required
         documentary evidence, the Borrowers shall indemnify the Agent and any
         Lender for any incremental Non-Excluded 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 Section 4.4 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:

                                    (i) (A) on or before the date of any payment
                                    by the Borrowers under this Credit Agreement
                                    or the Notes to such Lender, deliver to the
                                    Borrowers and the Agent (x) two duly

                                    Revenue Service Form W-8BEN or W-8ECI, or
                                    any 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 (y) 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;

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

                                    certifications as may reasonably be
                                    requested by the Borrowers or the Agent; or

                           (ii) 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, (A) 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, (B) agree to furnish to the Borrowers, on or
                  before the date of any payment by the Borrowers, with a copy
                  to the Agent, two 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 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 (C)
                  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.

                           Notwithstanding the above, if 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, then such
                  Lender shall be exempt from such requirements. 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 (b); 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.

         4.5 REPLACEMENT OF LENDERS.

         The Agent and each Lender shall use reasonable efforts to avoid or
mitigate any increased cost or suspension of the availability of an interest
rate under Sections 4.1 through 4.4 above to the greatest extent practicable
(including transferring the Loans to another lending






                                       34
<PAGE>   39

office or Affiliate of a Lender) unless, in the opinion of the Agent or such
Lender, such efforts would be likely to have an adverse effect upon it. In the
event a Lender makes a request to the Borrowers for additional payments in
accordance with Section 4.1, 4.2 or 4.4, or suspends Eurodollar Loans under
Section 4.1, then, provided that no Default or Event of Default has occurred and
is continuing at such time, the Borrowers may, at their own expense (such
expense to include any transfer fee payable to the Agent under Section 11.3(b)
and any expense pursuant to Section 4) and in its sole discretion, require such
Lender to transfer and assign in whole (but not in part), without recourse (in
accordance with and subject to the terms and conditions of Section 11.3(b)), all
of its interests, rights and obligations under this Credit Agreement to an
Eligible Assignee which shall assume such assigned obligations (which assignee
may be another Lender, if a Lender accepts such assignment); provided that (a)
such assignment shall not conflict with any law, rule or regulation or order of
any court or other Governmental Authority and (b) the Borrowers or such assignee
shall have paid to the assigning Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the portion of
the Loans hereunder held by such assigning Lender and all other amounts owed to
such assigning Lender hereunder, including amounts owed pursuant to Sections 4.1
through 4.4.


                                   SECTION 5.

preserve any such existence, right or franchise if it in good faith determines
that preservation thereof is no longer necessary or desirable in the conduct of
its business and that the loss thereof is not disadvantageous in any material
respect to the Lenders.

         7.3 BOOKS AND RECORDS.

         Each Borrower will keep, and will cause its Material Subsidiaries to
keep, complete and accurate books and records of its transactions in accordance

         Each Borrower will comply, and will cause each Material Subsidiary to
comply, with all laws (including, without limitation, all Environmental Laws and
ERISA laws), rules, regulations and orders, and all applicable restrictions
imposed by all Governmental Authorities, applicable to it and its property, if
(a) the failure to comply would have or would be reasonably expected to have a
Material Adverse Effect or (b) the necessity of compliance therewith is being
contested in good faith by appropriate proceedings.

         7.5 PAYMENT OF TAXES AND OTHER INDEBTEDNESS.

         Each Borrower will, and will cause each Material Subsidiary to, pay,
settle or discharge (a) all taxes, assessments and governmental charges or
levies imposed upon it, or upon its income or profits, or upon any of its
properties, before they shall become delinquent, (b) all lawful claims
(including claims for labor, materials and supplies) which, if unpaid, might
give rise to a Lien upon any of its properties, and (c) all of its other
Indebtedness as it shall become due; provided, however, that no Borrower shall
be required to pay any such tax, assessment, charge, levy, claim or Indebtedness
which (i) is being contested in good faith by appropriate proceedings and as to
which adequate reserves therefor have been established in accordance with GAAP
or (ii) the nonpayment of which would not have a Material Adverse Effect.

         7.6 MAINTENANCE OF PROPERTY; INSURANCE.

                  (a) Each Borrower will keep, and will cause each Material
         Subsidiary to keep, all property useful and necessary in its business
         in good working order and condition, ordinary wear and tear excepted.

                  (b) Each Borrower will, and will cause each of its Material
         Subsidiaries to, maintain (either in the name of such Borrower or in
         such Material Subsidiary's own name) with financially sound and
         responsible insurance companies, insurance on all their respective
         properties in at least such amounts and against at least such risks
         (and with such risk retention) as are usually insured against in the
         same general area by companies of established repute engaged in the
         same or a similar business; provided that self-insurance by a Borrower
         or any such Material Subsidiary shall not be deemed a





                                       44

         violation of this covenant to the extent that companies engaged in
         similar businesses and owning similar properties in the same general
         areas in which the Borrowers or such Material Subsidiary operates
         self-insure.

         7.7 USE OF PROCEEDS.

         The proceeds of the Loans may be used solely (a) to provide credit
support for each Borrower's commercial paper and (b) for working capital and
other general corporate purposes of each Borrower. The Borrowers will use the
Letters of Credit solely for the purposes set forth in Section 2.2(a).

         7.8 AUDITS/INSPECTIONS.

         Upon reasonable notice and during normal business hours, each Borrower

appointed by the Agent, including, without limitation, independent accountants,
agents, attorneys, and appraisers to visit and inspect each Borrower's and its
Material Subsidiaries' property, including its books and records, its accounts
receivable and inventory, each Borrower's and its Material Subsidiaries'
facilities and its other business assets, and to make photocopies or photographs
thereof and to write down and record any information such representatives obtain

         Each Borrower will maintain ownership of all Capital Stock of each
Material Subsidiary, directly or indirectly, free and clear of all Liens except
as permitted by Section 8.3. The Borrowers will take such action as necessary to
ensure that, on and after the date of the Merger, Duke Energy Field Services,
LLC will be (and will remain) a wholly owned Subsidiary, direct or indirect, of
Duke Energy Field Services Corporation unless Duke Energy Field Services, LLC is
merged with and into Duke Energy Field Services Corporation.

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

                  (ii) Acceleration of Loans and Letters of Credit. 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 a Borrower to 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.




                                       51
<PAGE>   56

                  (iii) Cash Collateral. Direct the Borrowers to pay (and the
         Borrowers 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 Issuing Lender additional cash, to be held by
         the Issuing Lender, for the benefit of the Lenders, in a cash
         collateral account as 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.

                  (iv) Enforcement of Rights. Enforce any and all rights and
         interests created and existing under the Credit Documents, including,
         without limitation, 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 under Letters of Credit, all accrued
interest in respect thereof, all accrued and unpaid fees and other indebtedness
or obligations owing to the Lenders and the Agent hereunder shall immediately
become due and payable without the giving of any notice or other action by the
Agent or the Lenders.

Notwithstanding the fact that enforcement powers reside primarily with the
Agent, each Lender has, to the extent permitted by law, a separate right of
payment and shall be considered a separate "creditor" holding a separate "claim"
within the meaning of Section 101(5) of the Bankruptcy Code or any other
insolvency statute.

         9.3 ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.

         Notwithstanding any other provision of this Credit Agreement, after the
occurrence of an Event of Default, all amounts collected or received by the
Agent or any Lender on account of 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 attorneys' fees)
         of the Agent and the Lenders in connection with enforcing the rights of
         the Lenders under the Credit Documents, pro rata as set forth below;

                  SECOND, to payment of any fees owed to the Agent, or any
         Lender, pro rata as set forth below;

                  THIRD, to the payment of all accrued interest payable to the
         Lenders hereunder, pro rata as set forth below;

                  FOURTH, to the payment of the outstanding principal amount of
         the Loans and to the payment or cash collateralization of the
         outstanding LOC Obligations, pro rata, as set forth below;




                                       52
<PAGE>   57

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

                  SIXTH, to the payment of the surplus, if any, to whomever may
         be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category; (b) each of the Lenders shall receive an amount equal to
its pro rata share (based on the proportion that the then outstanding Loans and
LOC Obligations held by such Lender bears to the aggregate then outstanding
Loans and LOC Obligations), of amounts available to be applied; and (c) to the
extent that any amounts available for distribution pursuant to clause "FOURTH"
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 (i) first, to reimburse the Issuing Lender from time to time for any
drawings under such Letters of Credit and (ii) then, following the expiration of
all Letters of Credit, to all other obligations of the types described in
clauses "FOURTH", "FIFTH" and "SIXTH" above in the manner provided in this
Section 9.3.


                                   SECTION 10

                                AGENCY PROVISIONS

         10.1 APPOINTMENT.

         Each Lender hereby designates and appoints Bank of America, N.A. as
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 Borrowers 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 a Borrower. All institutions acting as a Co-Syndication Agent or
Co-Documentation Agent hereunder shall have no obligations in such capacity
under the Credit Documents.




                                       53
<PAGE>   58

         10.2 DELEGATION OF DUTIES.

         The Agent may execute any of its 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 to the Lenders for the negligence or misconduct of any
agents or attorneys-in-fact selected by it with reasonable care.

         10.3 EXCULPATORY PROVISIONS.

         Neither the Agent nor any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates shall be 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 responsible in
any manner to any of the Lenders for any recitals, statements, representations
or warranties made by a Borrower contained herein or in any of the other Credit
Documents or in any certificate, report, statement or other document 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 a Borrower
to perform its 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 a Borrower 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 a Borrower
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 of the existence or possible existence of any Default or Event of
Default or to inspect the properties, books or records of a Borrower. The Agent
is not a trustee for the Lenders and owes no fiduciary duty to the Lenders.

         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 its 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). 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








                                       54
<PAGE>   59

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 the Borrowers 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 reasonably
directed by the Required Lenders.

         10.6 NON-RELIANCE ON AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that neither the Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by the Agent or any
Affiliate thereof hereinafter taken, including any review of the affairs of the
Borrowers, shall be deemed to constitute any representation or warranty by the
Agent to any Lender. Each Lender represents to the Agent that it has,
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Borrowers
and made its own decision to make its Extensions of Credit 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
Borrowers. 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 Borrowers 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.

         Each Lender agrees to indemnify the Agent in its capacity as such (to
the extent not reimbursed by the Borrowers and without limiting the obligation
of the Borrowers to do so), ratably according to its Commitment Percentage, from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including without limitation at any time
following the payment







                                       55
<PAGE>   60

in full of the Borrowers Obligations) 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 10.7
shall survive the payment of the Borrowers Obligations and all other amounts
payable hereunder and under the other Credit Documents and the termination of
the Commitments.

         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 Borrowers as though the
Agent were not Agent hereunder. With respect to the Loans made, Letters of
Credit issued and all Borrowers Obligations owing to it, the Agent shall have
the same rights and powers under this Credit Agreement as any Lender and may
exercise the same as though it were not the Agent, and the terms "Lender" and
"Lenders" shall include the Agent in its individual capacity.

         10.9 SUCCESSOR AGENT.

         The Agent may, at any time, resign upon 30 days written notice to the
Lenders and the Borrowers. Upon any such resignation, the Borrowers with the
consent of the Required Lenders (such consent of the Required Lenders not to be
unreasonably withheld or delayed) shall have the right to appoint a successor
Agent. If no successor Agent shall have been so appointed and shall have
accepted such appointment within 30 days after the notice of resignation, then
the retiring Agent shall select a successor Agent provided such successor is a
Lender hereunder or qualifies as an Eligible Assignee (or if no Eligible
Assignee 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 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.

                                   SECTION 11.

                                  MISCELLANEOUS

         11.1 NOTICES.

         Except as otherwise expressly provided herein, all notices and other
communications shall have been duly given and shall be effective (a) when
delivered, (b) when transmitted via telecopy (or other facsimile device), (c)
the Business Day following the day on which the same has been delivered prepaid
(or pursuant to an invoice arrangement) to a reputable national overnight air
courier service, or (d) the third Business Day following the day on which the
same is sent by certified or registered mail, postage prepaid, in each case to
the respective parties at the address or telecopy numbers set forth on Schedule
11.1, or at such other address as such party may specify by written notice to
the other parties hereto.

         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 and the commencement of remedies described in
Section 9.2, 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 a Borrower against obligations and liabilities of such Borrower to
the Lenders hereunder, under the Notes, the other Credit Documents or otherwise,
irrespective of whether the Agent or the Lenders 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.

         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, except as set forth
         in Section 2.10, a Borrower may not assign and transfer any of its
         interests without the prior written consent of the Lenders; and
         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 below in this Section 11.3.




                                       57
<PAGE>   62

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

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

                           (ii) except in the case of an assignment to another
                  Lender or an assignment of all of a Lender's rights and
                  obligations under this Credit Agreement, any such partial
                  assignment shall be in an amount at least equal to $10,000,000
                  (or, if less, the remaining amount of the Commitment being
                  assigned by such Lender) and an integral multiple of
                  $1,000,000 in excess thereof; and

                           (iii) the parties to such assignment shall execute
                  and deliver to the Agent for its acceptance an Assignment
                  Agreement in substantially the form of Exhibit 11.3(b),
                  together with a processing fee from the assignor of $3,500.

         Upon execution, delivery, and acceptance of such Assignment Agreement,
         the assignee thereunder shall be a party hereto and, to the extent of
         such assignment, have the obligations, rights, and benefits of a Lender
         hereunder and the assigning Lender shall, to the extent of such
         assignment, relinquish its rights (except those rights hereunder which
         by their terms expressly survive) and be released from its obligations
         under this Credit Agreement. Upon the consummation of any assignment
         pursuant to this Section 11.3(b), the assignor, the Agent and the
         Borrowers shall make appropriate arrangements so that, if required, new
         Notes are issued to the assignor and the assignee. If the assignee is
         not incorporated under the laws of the United States of America or a
         state thereof, it shall deliver to the Borrowers and the Agent
         certification as to exemption from deduction or withholding of taxes in
         accordance with Section 4.4.

                  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: (A) 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
         created by such assigning Lender and the assignee warrants that it is
         an Eligible Assignee; (B) except as set forth in clause (A) 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 or thereto or the
         financial condition of the Borrowers or the performance or observance
         by the Borrowers 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; (C) such assigning
         Lender and such







                                       58
<PAGE>   63

         assignee represents and warrants that it is legally authorized to enter
         into such assignment agreement; (D) 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; (E) 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; (F) 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 (G) 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) Register. The Agent shall maintain a copy of each
         Assignment Agreement delivered to and accepted by it and a register for
         the recordation of the names and addresses of the Lenders and the
         Commitment of, and principal amount of the Loans owing to, each Lender
         from time to time (the "Register"). The entries in the Register shall
         be conclusive and binding for all purposes, absent manifest error, and
         the Borrowers, the Agent and the Lenders may treat each Person whose
         name is recorded in the Register as a Lender hereunder for all purposes
         of this Credit Agreement. The Register shall be available for
         inspection by the Borrowers or any Lender at any reasonable time and
         from time to time upon reasonable prior notice.

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

                  (e) Participations. Each Lender may sell participations to one
         or more Persons in all or a portion of its rights, obligations or
         rights and obligations under this Credit Agreement (including all or a
         portion of its Commitment, its Notes and its Loans); provided, however,
         that (i) such Lender's obligations under this Credit Agreement shall
         remain unchanged, (ii) such Lender shall remain solely responsible to
         the other parties hereto for the performance of such obligations, (iii)
         the participant shall be entitled to the benefit of the yield
         protection provisions contained in Sections 4.1 through 4.4, inclusive,
         but shall not be entitled to receive any amount greater than such
         Lender would have been able to receive, and (iv) the Borrowers shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Credit Agreement,
         and such Lender shall retain the sole right to enforce the obligations
         of the Borrowers relating to its Loans and its Notes and to approve any
         amendment,





                                       59

         modification, or waiver of any provision of this Credit Agreement
         (other than amendments, modifications, or waivers decreasing the amount
         of principal of or the rate at which interest is payable on such Loans
         or Notes, extending any scheduled principal payment date or date fixed
         for the payment of interest on such Loans or Notes, or extending its
         Commitment).

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

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

         11.4 NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Agent or any Lender in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Borrowers and the Agent or any
Lender 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
Borrowers in any case shall entitle the Borrowers 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 Borrowers agree to: (i) pay all reasonable out-of-pocket costs and
expenses of the Agent and Banc of America Securities LLC ("BAS") in connection
with (A) the negotiation, preparation, execution and delivery, syndication 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 (B) 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 Borrowers under this Credit Agreement, (ii) pay all
reasonable out-of-pocket costs and expenses of the Agent and each Lender in
connection with (A) enforcement of the Credit Documents and the documents and

counsel)) and (B) any bankruptcy or insolvency proceeding of a Borrower




                                       60

and (iii) indemnify the Agent, BAS 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, any investigation, litigation or other proceeding (whether or not the
Agent, BAS or 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
(including 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 and settlement
costs incurred in connection with any such investigation, litigation or other
proceeding (but excluding any such losses, liabilities, claims, damages or
expenses to the extent incurred by reason of negligence or willful misconduct on
the part of the Person to be indemnified).

         11.6 AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement, nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or

writing and signed by the Required Lenders and the Borrowers; provided that no
such amendment, change, waiver, discharge or termination shall without the
consent of each Lender affected thereby:

                  (a) extend the Maturity Date or the Term Out Maturity Date, or
         postpone or extend the time for any payment or prepayment of principal

         thereof, arising from drawings under Letters of Credit;

                  (b) reduce the rate or extend the time of payment of interest
         thereon or fees or other amounts payable hereunder;

                  (c) reduce or waive the principal amount of any Loan or of any

         under Letters of Credit;

                  (d) increase or extend the Commitment of a Lender (it being
         understood and agreed that a waiver of any Default or Event of Default
         or a waiver of any mandatory reduction in the Commitments shall not
         constitute a change in the terms of any Commitment of any Lender);

                  (e) except as permitted by Section 2.10, consent to the
         assignment or transfer by a Borrower of any of its rights and

                                       61
<PAGE>   66

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

No provision of Section 10 may be amended or modified without the consent of the
Agent.

Notwithstanding the fact that the consent of all 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 supersede the unanimous consent provisions set
forth herein and (y) the Required Lenders may consent to allow the Borrowers to
use cash collateral in the context of a bankruptcy or insolvency proceeding.

         11.7 COUNTERPARTS/TELECOPY.

         This Credit Agreement may be executed in any number of counterparts,
each of which where so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. Delivery of executed
counterparts by telecopy shall be as effective as an original and shall
constitute a representation that an original will be delivered.

         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 DEFAULTING LENDER.

         Each Lender understands and agrees that if such Lender is a Defaulting
Lender then it shall not be entitled to vote on any matter requiring the consent
of the Required Lenders or to object to any matter requiring the consent of all
the Lenders; provided, however, that (a) a Lender's Commitment may not be
increased without its consent whether or not it is a Defaulting Lender and (b)
all other benefits and obligations under the Loan Documents shall apply to such
Defaulting Lender.

         11.10 SURVIVAL OF INDEMNIFICATION AND REPRESENTATIONS AND WARRANTIES.

         All indemnities set forth herein and all representations and warranties
made herein shall survive the execution and delivery of this Credit Agreement,
the making of the Loans, the issuance of the Letters of Credit and the repayment
of the Loans, LOC Obligations and other obligations and the termination of the
Commitments hereunder.

         11.11 GOVERNING LAW; 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






                                       62
<PAGE>   67

         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, each Borrower hereby irrevocably accepts for itself and in
         respect of its property, generally and unconditionally, the
         jurisdiction of such courts. Each Borrower further irrevocably consents
         to the service of process out of any of the aforementioned courts in
         any such action or proceeding by the mailing of copies thereof by
         registered or certified mail, postage prepaid, to it at the address for
         notices pursuant to Section 11.1, such service to become effective 30
         days after such mailing. Nothing herein shall affect the right of a
         Lender to serve process in any other manner permitted by law or to
         commence legal proceedings or to otherwise proceed against a Borrower
         in any other jurisdiction.

                  (b) Each Borrower hereby irrevocably waives any objection
         which it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this 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 such court has been
         brought in an inconvenient forum.

         11.12 WAIVER OF JURY TRIAL; WAIVER OF CONSEQUENTIAL DAMAGES.

         EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR
THE TRANSACTIONS CONTEMPLATED HEREBY. Each Borrower agrees not to assert any
claim against the Agent, any Lender, any of their Affiliates, or any of their
respective directors, officers, employees, attorneys or agents, on any theory of
liability, for special, indirect, consequential or punitive damages arising out
of or otherwise relating to any of the transactions contemplated hereby or by
the other Credit Documents.

         11.13 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.

<PAGE>   68

         11.14 FURTHER ASSURANCES.

         Each Borrower agrees, upon the request of the Agent, to promptly take
such actions, as reasonably requested, as are necessary to carry out the intent
of this Credit Agreement and the other Credit Documents.

         11.15 ENTIRETY.

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

         11.16 BINDING EFFECT; CONTINUING AGREEMENT.

                  (a) This Credit Agreement shall become effective at such time
         when all of the conditions set forth in Section 5.1 have been satisfied
         or waived by the Lenders and it shall have been executed by the
         Borrowers, the Agent and the Lenders, and thereafter this Credit
         Agreement shall be binding upon and inure to the benefit of the
         Borrowers, the Agent and each Lender and their respective successors
         and permitted assigns.

                  (b) This Credit Agreement shall be a continuing agreement and
         shall remain in full force and effect until all Loans, LOC Obligations,
         interest, fees and other Borrowers Obligations have been paid in full
         and all Commitments and Letters of Credit have been terminated. Upon
         such termination, the Borrowers shall have no further obligations
         (other than those provisions that expressly survive the termination
         thereof) under the Credit Documents; provided that should any payment,
         in whole or in part, of the Borrowers Obligations be rescinded or
         otherwise required to be restored or returned by the Agent or any
         Lender, whether as a result of any proceedings in bankruptcy or
         reorganization or otherwise, then the Credit Documents shall
         automatically be reinstated and all amounts required to be restored or
         returned and all costs and expenses incurred by the Agent or any Lender
         in connection therewith shall be deemed included as part of the
         Borrowers Obligations.
