              CREDIT AGREEMENT, dated as of May 30, 2000, among Iroquois Gas
Transmission System, L.P., a Delaware limited partnership (the "Borrower"), the
several banks and other financial institutions from time to time parties to this
Agreement (the "Lenders"), The Chase Manhattan Bank, as administrative agent for
the Lenders hereunder (in such capacity, together with its successors in such
capacity, the "Administrative Agent"), Bank of Montreal, as syndication agent
for the Lenders hereunder (in such capacity, the "Syndication Agent") and Fleet
National Bank, as documentation agent for the Lenders hereunder (in such
capacity, the "Documentation Agent").

              The Borrower was formed to plan, design, construct, own and
operate the Pipeline (as hereinafter defined) for the transmission of natural
gas from a point of interconnection with facilities of TransCanada PipeLines
Limited near Iroquois, Ontario, Canada, across eastern New York, western
Connecticut and under Long Island Sound to a point of interconnection with
facilities of the New York Facilities System near South Commack, Long Island,
New York. The Borrower has completed the planning, design and construction of
the Pipeline and now owns and, through a wholly-owned Subsidiary, commercially
operates the Pipeline. As of the date hereof, the Borrower has 33 Shippers under
long-term firm service transportation contracts and the Pipeline's capacity,
currently 987 MDth/d, is fully subscribed.

              Pursuant to a loan agreement, dated as of May 30, 1991 (as amended
to the date hereof, the "Existing Loan Agreement"), among the Borrower and the
financial institutions party thereto, such financial institutions made loans to
the Borrower to finance a portion of the construction costs of the Pipeline.

              The Borrower has requested the Lenders to extend credit in the
form of (a) Term Loans on the Closing Date, in an aggregate principal amount not
in excess of $200,000,000, and (b) Revolving Credit Loans at any time and from
time to time prior to the Revolving Credit Termination Date, in an aggregate
principal amount at any time outstanding not in excess of $10,000,000.

              The proceeds of the Term Loans will be used by the Borrower to
repay in full the aggregate principal amount of loans outstanding under the
Existing Loan Agreement and thereafter for general corporate purposes. Proceeds
of Revolving Credit Loans may be used by the Borrower for general corporate
purposes.

              In consideration of the premises, and of the mutual covenants and
agreements herein contained and other good and valuable consideration, receipt
of which is hereby acknowledged, the parties hereto hereby agree as follows:

                             SECTION 1. DEFINITIONS

         such date plus 1% and (c) the Federal Funds Effective Rate in effect on
         such day plus 1/2 of 1%. Any change in the ABR due to a change in the
<PAGE>

         Prime Rate, the Three-Month Secondary CD Rate or the Federal Funds
         Effective Rate shall be effective as of the opening of business on the
         effective day of such change in the Prime Rate, the Three-Month
         Secondary CD Rate or the Federal Funds Effective Rate, respectively.

              "ABR Loan" means Loans as to which the applicable rate of interest
         is based upon ABR.

         directly, or indirectly through one or more intermediaries, controls,
         is controlled by or is under common control with the Person specified,
         or who holds or beneficially owns 10% or more of the equity interest in
         the Person specified or 10% or more of any class of voting securities
         of the Person specified. For the purposes of this definition, the term
         "control" (including, with correlative meanings, the terms "controlled
         by" and "under common control with"), as used with respect to any
         Person, shall mean the possession, directly or indirectly, of the power
         to direct or cause the direction of the management and policies of such

         contract or otherwise.

              "Affiliate Subordinated Debt" means unsecured Indebtedness of the
         Borrower held by any Affiliate of the Borrower, any Partner or an
         Affiliate of any Partner and subordinated to the Senior Debt on the

         under the caption "Eurodollar Loan" or "ABR Loan" below the caption
         "Swingline Loans and Revolving Credit Loans" and (c) any Facility Fee,

         provided that with respect to Eurodollar Loans which are Term Loans,
         (1) from and after the third anniversary of the Closing Date, the
         Applicable Margin for such Loans shall be increased by 0.25% in each of
         the Levels above and (2) from and after the sixth anniversary of the
         Closing Date, the Applicable Margin for such Loans shall be increased
         by an additional 0.25% in each of the Levels above. In the event the
         public debt of the Borrower receives a split rating from S&P and

         such ratings in the event such ratings are one level apart, (2) the
         level immediately below the level with the higher of such ratings in
         the event such ratings are two or three levels apart and (3) the second

         the event such ratings are four levels apart. If at any time no rating
         is available from S&P and Moody's or any other nationally recognized
         statistical rating organization designated by the Borrower and approved
         in writing by the Majority Lenders, the Applicable Margin for each
         Interest Period or each other period commencing during the thirty days
         following such ratings becoming unavailable shall be the Applicable
         Margin in effect immediately prior to such ratings becoming
         unavailable. Thereafter the rating to be used for purposes of this
         Agreement until ratings from S&P and Moody's become available shall be
         as agreed between the Borrower and the Administrative Agent, and the
         Borrower and Administrative Agent shall use good faith efforts to reach
         such agreement within such thirty day period; provided, however, that
         if no such agreement is reached within such thirty day period the
         Applicable Margin thereafter, until such agreement shall have been
         reached, shall be (A) if any such rating shall have become unavailable
         as a result of S&P or Moody's ceasing its business as a rating agency,
         the Applicable Margin in effect immediately prior to such cessation or
         (B) otherwise, the Applicable Margin as set forth under Level IV above.

              "Asset Sale" means any sale, transfer, sale-leaseback transaction
         or other disposition (excluding a merger or consolidation which is in
         compliance with the covenant set forth in subsection 6.4) in one

         Person of (i) all or any of the Capital Stock of any Subsidiary, (ii)
         all or substantially all of the property and assets of an operating
         unit or business of the Borrower or any of its Subsidiaries or (iii)

         course of business of the Borrower that is not governed by the
         provisions hereof applicable to mergers, consolidations and sales of
         assets of the Borrower; provided that "Asset Sale" shall not include
         (a) sales or other dispositions of inventory, receivables and other
         current assets or (b) Distributions permitted to be made

                                       3

              2.3 Swingline Commitment. (a) Subject to and upon the terms and
conditions of this Agreement, Chase in its individual capacity agrees to make a
loan or loans (each, a "Swingline Loan" and collectively, the "Swingline Loans")
to the Borrower, which Swingline Loans (i) shall be made at any time and from
time to time from and after the Closing Date and prior to the Swingline Maturity
Date, (ii) may be repaid and reborrowed in accordance with the

                                       24
<PAGE>

terms hereof, (iii) shall not exceed the Swingline Commitment at such time and
(iv) shall not, after giving effect thereto and the application of the proceeds
thereof, when added to the aggregate principal amount of the Revolving Credit
Loans then outstanding exceed in the aggregate the Total Revolving Credit
Commitment then in effect. On the Swingline Maturity Date, all Swingline Loans
shall be repaid in full.

              (b) The proceeds of the Swingline Loans shall be used by the
Borrower exclusively for the purposes described in clause (b) of subsection
3.17.

              (c) Subject to subsection 2.12, the Swingline Loans may from time
to time be (i) Eurodollar Loans, (ii) ABR Loans or (iii) a combination thereof,
as determined by the Borrower and notified to the Administrative Agent in
accordance with subsections 2.5 and 2.11.

              (d) On any Business Day, Chase may, in its sole discretion, give
notice to the Lenders that all then-outstanding Swing Loans shall be funded with
a borrowing of Revolving Credit Loans, in which case a borrowing of Revolving
Credit Loans constituting ABR loan (each such borrowing a "Mandatory Borrowing")
shall be made on the immediately succeeding Business Day by all Lenders pro rata
based on each Lender's Commitment Percentage, and the proceeds thereof shall be
applied directly to Chase to repay Chase for such outstanding Swingline Loans.
Each Lender hereby irrevocably agrees to make such Revolving Credit Loans upon
one Business Day's notice pursuant to each Mandatory Borrowing in the amount and
in the manner specified to it in writing by Chase notwithstanding (i) that the
amount of the Mandatory Borrowing may not comply with the minimum amount for
each Borrowing specified in Section 2.12, (ii) whether any conditions specified
in Section 4 are then satisfied, (iii) whether a Default or an Event of Default
has occurred and is continuing, (iv) the date of such Mandatory Borrowing or (v)
any reduction in the Total Revolving Credit Commitment after any such Swingline
Loans were made. In the event that, in the sole judgment of Chase, 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 in respect of the Borrower), each Lender hereby agrees
that it shall forthwith purchase from Chase (without recourse or warranty) such
participation of the outstanding Swingline Loans as shall be necessary to cause
the Lenders to share in such Swingline Loans ratably based on their respective
Commitment Percentages, provided that all principal and interest payable on such
Swingline Loans shall be for the account of Chase until the date the respective
participation is purchased and, to the extent attributable to the purchased
participation, shall be payable to the Lender purchasing same from and after
such date of purchase.

              2.4 Evidence of Debt. (a) Each Lender shall maintain in
accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower to the appropriate lending office of such Lender
resulting from each Loan made by such lending office to such Lender from time to
time, including the amounts of principal and interest payable and paid to such
lending office of such Lender from time to time under this Agreement.

              (b) The Administrative Agent shall maintain the Register pursuant
to subsection 10.6(d), and a subaccount for each Lender, in which Register and
subaccounts (taken together) shall be recorded (i) the amount of each Loan made
hereunder, whether such Loan is a Term Loan, a Swingline Loan or a Revolving
Credit Loan, the Type of each Loan made and the

                                       25
<PAGE>

Interest Period applicable thereof, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof.

              (c) The entries made in the Register and accounts and subaccounts
maintained pursuant to paragraphs (a) and (b) of this subsection 2.4 shall, to
the extent permitted by applicable law, be prima facie evidence of the existence
and amounts of the obligations of the Borrower therein recorded; provided,
however, that the failure of any Lender or the Administrative Agent to maintain
such account, such Register or such subaccount, as applicable, or any error
therein shall not in any manner affect the obligation of the Borrower to repay
(with applicable interest) the Loans made to the Borrower by such Lender in
accordance with the terms of this Agreement.

              (d) In order to facilitate any pledge or assignment as provided in
subsection 10.6(h), the Borrower hereby agrees that, upon request of any Lender
at any time and from time to time after the Borrower has made its initial
borrowing hereunder, the Borrower shall provide to such Lender, at the
Borrower's own expense, a promissory note, substantially in the form of Exhibit
A-1 or A-2, as the case may be, evidencing the Term Loans and Revolving Credit
Loans, respectively owing to such Lender.

              2.5 Procedure for Borrowings. Each borrowing by the Borrower
hereunder shall be on a Working Day, if all or any part of such Loans initially
are to be Eurodollar Loans, or a Business Day, if all or any part of such Loans
initially are to be ABR Loans, provided that the Borrower shall deliver to the
Administrative Agent a Borrowing Certificate (which certificate, to be effective
on the requested Borrowing Date, must be received by the Administrative Agent
(i) prior to 12:00 Noon, New York City time, three (3) Working Days prior to the
requested Borrowing Date, if all or any part of such Loans initially are to be
Eurodollar Loans or (ii) prior to 10:00 A.M., New York City time, on the
requested Borrowing Date, if all or any part of such Loans initially are to be
ABR Loans, provided that if such certificate is received after the specified
time on the relevant Working Day or Business Day, such certificate shall be
effective, and the requested Borrowing Date shall be deemed to be, the Working
Day or Business Day (as applicable) next succeeding the requested Borrowing Date
specified in such certificate), specifying (A) the amount to be borrowed, (B)
the requested Borrowing Date, (C) whether such Loans are to be Eurodollar Loans,
ABR Loans or a combination thereof and (D) if such Loans are to be entirely or
partly Eurodollar Loans, the respective amounts of such Type of Loan and the
respective durations of the initial Interest Periods therefor. Such Borrowing
Certificate shall also identify such Loans as Term Loans, Swingline Loans or
Revolving Credit Loans. Each borrowing of Swingline Loans and Revolving Credit
Loans shall be in an amount equal to $1,000,000 or a whole multiple thereof (or
such lesser amount as shall equal the then unborrowed amount of the Total
Revolving Credit Commitment). Upon receipt of each Borrowing Certificate, the
Administrative Agent shall promptly notify each Lender thereof. Each Lender will
make the amount of its pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the office of the
Administrative Agent specified in subsection 10.2 prior to 12:00 Noon, New York
City time, on the Borrowing Date requested by the Borrower in funds immediately
available to the Administrative Agent. The Administrative Agent then will make
the amount of such

                                       26
<PAGE>

borrowing available to the Borrower prior to 2:00 P.M., New York City time, on
such date (i) by crediting the account of the Borrower on the books of such
office with the aggregate of the amounts made available to the Administrative
Agent by the Lenders and in like funds as received by the Administrative Agent,
or (ii) if so requested by the Borrower in the related Borrowing Certificate, by
initiating the transfer of such amounts made available to the Administrative
Agent in like funds to the Federal Reserve Bank of New York for the account of a
member bank designated by the Borrower in such Borrowing Certificate.

              2.6 Fees.  (a) The Borrower agrees to pay to the Administrative
Agent, for the account of each Lender having a Revolving Credit Commitment (in
each case pro rata according to the respective Revolving Credit Commitments of
all such Lenders), a facility fee on the daily average of such Lenders'
Revolving Credit Commitments (regardless of utilization thereof), for the period
from and including the Closing Date to but excluding the Final Date. Such
facility fee shall be computed for each day during such period at a rate per
annum equal to the percentage set forth in the definition of Applicable Margin
under the caption "Facility Fee" for such day on the Total Revolving Credit
Commitment in effect on such day. Each such facility fee shall be payable
quarterly in arrears on the last day of each March, June, September and
December, commencing on the first of such dates to occur after the date hereof,
and on the Final Date.

              (b) The Borrower agrees to pay to the Administrative Agent, for
its own account, the arrangement fee set forth in the Fee Letter. Such
arrangement fee shall be payable on the Closing Date.

              (c) The Borrower agrees to pay the Administrative Agent, for its
own account, the annual administration fee set forth in the Fee Letter. The
first annual payment of such administration fee shall be payable on the Closing
Date and each subsequent annual payment shall be payable on each anniversary of
the Closing Date during the term of this Agreement.

              2.7 Reductions and Terminations of Commitments. (a) The Borrower
may, upon not less than five (5) Business Days' prior irrevocable notice to the
Administrative Agent, terminate in whole, or from time to time reduce, the then
unborrowed amount of the Total Revolving Credit Commitment; provided that prior
to or concurrently with the receipt of notice of any such termination or
reduction, the Lenders shall have received evidence, satisfactory to the
Administrative Agent that, together with a certificate from a Responsible
Officer stating that, after giving effect to such termination or reduction, the
Borrower will be in compliance with subsection 5.6. Any such termination or
reduction shall be in a minimum amount of $500,000 and shall reduce permanently
the Total Revolving Credit Commitment. Each reduction of the Total Revolving
Credit Commitment pursuant to this subsection shall automatically and
permanently reduce the Swingline Commitment by the same amount.

              (b) The Total Revolving Credit Commitment shall terminate at 5:00
P.M. (New York time) on the Revolving Credit Termination Date.

              (c) The Swingline Commitment shall terminate at 5:00 P.M. (New
York time) on the Swingline Maturity Date.

                                       27
<PAGE>

              (d) The Total Term Loan Commitment shall terminate at 5:00 P.M.
(New York time) on the Closing Date.

              2.8 Repayment of Loans.

              (a) The Borrower shall repay to the Administrative Agent, for the
benefit of the Lenders, (i) on the Term Loan Maturity Date, the then unpaid Term
Loans, (ii) on the Revolving Credit Termination Date, the then unpaid Revolving
Credit Loans and (iii) on the Swingline Maturity Date, the then unpaid Swingline
Loans.

              (b) The Borrower shall repay to the Administrative Agent, for the
benefit of the Lenders, the principal amount of the Term Loans in thirty-five
equal quarterly payments of $5,555,555 (each a "Repayment Amount"), on each June
30, September 30, December 31 and March 31 (each a "Repayment Date") commencing
September 30, 2000, with the remaining unpaid principal balance of the Term
Loans to be paid on the Term Loan Maturity Date, provided, that (i) to the
extent that the aggregate principal amount of Term Loans outstanding at 5:00
P.M. (New York time) on the Closing Date is less than $200,000,000, the
Repayment Amounts shall be automatically be decreased, in inverse order of
maturity, by the amount of such difference and (ii) optional and mandatory
partial prepayments of Term Loans pursuant to subsection 2.9 or 2.10 shall be
applied to decrease pro rata the Repayment Amounts on and after the date of such
prepayments.

              2.9 Optional Prepayments. The Borrower may at any time and from
time to time prepay the Term Loans, Swingline Loans or the Revolving Credit
Loans, in whole or in part, without premium or penalty, in the case of
Eurodollar Loans, upon at least five (5) Business Days' prior irrevocable notice
to the Administrative Agent, and in the case of ABR Loans, upon at least one (1)
Business Day's prior irrevocable notice to the Administrative Agent. Each such
notice shall specify (a) the Loans to be prepaid on such date and amount of the
prepayment, (b) whether the prepayment is of Eurodollar Loans, ABR Loans or a
combination thereof, and, if of a combination thereof, the amount of the
prepayment allocable to each, and (c) whether the Loans to be prepaid are Term
Loans, Swingline Loans or Revolving Credit Loans, and, if a combination thereof,
the amount of the prepayment allocable to each. Upon receipt of any such notice,
the Administrative Agent shall promptly notify each Lender thereof. If any such
notice is given, the amount specified in such notice shall be due and payable on
the date specified therein, together with accrued interest to such date on the
amount to be prepaid and any amounts payable pursuant to subsection 2.20 with
respect to the Loans to be so prepaid. Partial prepayments shall be in an
aggregate principal amount of $2,000,000 or a whole multiple of $1,000,000 in
excess thereof.

              2.10 Mandatory Prepayments. (a) Unless the Majority Lenders shall
otherwise agree, upon the occurrence of (i) a Catastrophic Loss or (ii) a
Material Loss and, in the case of a Material Loss, within three (3) months after
receipt of such proceeds, the Management Committee or the Operator (if
authorized by the terms of the Operating Agreement to do so in the normal
performance of its duties) has not committed to use such proceeds to pay for the
repair or replacement of the affected portions of the Project (the Management
Committee's or the Operator's commitment so to use such proceeds to be in their
sole discretion and evidenced by the delivery to the Administrative Agent of a
certified copy of its resolution to such effect), the

                                       28
<PAGE>

Borrower shall prepay the Loans in an amount equal to the Pro Rata Portion of
the applicable Loss Proceeds.

              Prepayments of Loans pursuant to this subsection 2.10 shall be
made (x) on the first Interest Payment Date(s) next succeeding the date of
receipt of the proceeds referred to in clause (i) above and (y) on the first
Interest Payment Date(s) next succeeding the date three (3) months after the
receipt of the proceeds referred to in clause (ii) above. Partial prepayments
pursuant to this subsection 2.10 shall be applied: first, to the prepayment of
the Term Loans until the Term Loans shall be paid in full, and second, to the
permanent reduction of the Total Revolving Credit Commitment (and, to the extent
necessary, to the prepayment of first the Swingline Loans and second the
Revolving Credit Loans) until the Total Revolving Credit Commitment is reduced
to zero (and the Revolving Credit Loans shall be paid in full). Amounts prepaid
on the Loans pursuant to this subsection 2.10 may not be re-borrowed. Each
partial prepayment of Term Loans shall be applied to the installments of
principal thereof in the reverse order of their scheduled maturities. Each
reduction of the Total Revolving Credit Commitment pursuant to this subsection
shall automatically and permanently reduce the Swingline Commitment by the same
amount.

              (b) If on any date the sum of the outstanding principal amount of
the Revolving Credit Loans and Swingline Loans exceeds the Total Revolving
Credit Commitment as then in effect, the Borrower shall forthwith repay on such
date the principal amount of Swingline Loans and, after all Swingline Loans have
been paid in full, Revolving Credit Loans in an amount equal to such excess.

              2.11 Conversion and Continuation Options. (a) The Borrower may
elect from time to time to convert all or a portion of Eurodollar Loans to ABR
Loans by giving the Administrative Agent irrevocable notice of such election
(which notice, to be effective, must be received by the Administrative Agent
prior to 12:00 Noon, New York City time, three (3) Working Days prior to the
requested conversion date); provided that any such conversion of Eurodollar
Loans may only be made on the last day of an Interest Period with respect
thereto. The Borrower may elect from time to time to convert all or a portion of
ABR Loans to Eurodollar Loans by giving the Administrative Agent irrevocable
notice of such election (which notice, to be effective, must be received by the
Administrative Agent prior to 12:00 Noon, New York City time, three (3) Working
Days prior to the requested conversion date. Any such notice of conversion shall
specify (i) the aggregate principal amount being converted, (ii) the Type of
Loan such principal amount is being converted into, (iii) the requested
conversion date and (iv) in the case of a conversion to Eurodollar Loans shall
specify the duration of the initial Interest Period or Interest Periods
therefor. Upon receipt of any such notice the Administrative Agent shall
promptly notify each Lender thereof. All or any part of outstanding Eurodollar
Loans and ABR Loans may be converted as provided herein; provided that (i) no
Loan may be converted to a Eurodollar Loan when any Event of Default has
occurred and is continuing and the Majority Lenders have determined that such a
conversion is not appropriate and (ii) no such conversion maybe made if it would
contravene the provisions of subsection 2.12 or if it would not be permitted
under the provisions of subsection 2.15 or 2.17.

              (b) All or a portion of Eurodollar Loans (i) may be continued as
such upon the expiration of the then current Interest Period with respect
thereto by the Borrower giving notice

                                       29
<PAGE>

to the Administrative Agent (which shall promptly notify the Lenders), in
accordance with the applicable provisions of the term "Interest Period" set
forth in subsection 1.1, of the duration of the next Interest Period to be
applicable to such Loans, and (ii) shall be continued as such upon the
expiration of the current Interest Period with respect thereto for an Interest
Period of the same duration as such expiring Interest Period if the Borrower
shall fail to give the notice referred to in the preceding clause (i) or to give
a conversion notice in accordance with subsection 2.11(a); provided that no
Eurodollar Loan will be continued as such (A) when any Event of Default has
occurred and is continuing and the Majority Lenders have determined that such a
continuation is not appropriate or (B) if such continuation would contravene the
provisions of subsection 2.12 or if it would not be permitted under the
provisions of subsection 2.15 or 2.17; and provided, further, that if such
continuation is not permitted pursuant to the preceding proviso such Loans shall
be automatically converted to ABR Loans on the last day of such then expiring
Interest Period.

              2.12 Minimum Eurodollar Amount; Maximum Number of Tranches. All
borrowings, conversions and continuations of Loans hereunder and all selections
of Interest Periods hereunder shall be in such amounts and be made pursuant to
such elections so that, after giving effect thereto, (i) at no time will the
aggregate number of Eurodollar Tranches exceed ten and (ii) the aggregate
principal amount of any Eurodollar Tranche being continued or converted into
shall equal $5,000,000 or an integral multiple of $1,000,000 in excess thereof.
As used in this subsection 2.12 and in the definition of "Interest Period", the
term "Eurodollar Tranche" is the collective reference to Eurodollar Loans, the
Interest Periods with respect to which begin on the same date and end on the
same later date (whether or not such Eurodollar Loans shall originally have been
made on the same day).

              2.13 Interest Rates and Payment Dates. (a) Each Eurodollar Loan
shall bear interest for each day (including the first day but excluding the last
day) during each Interest Period with respect thereto at a rate per annum equal
to the Eurodollar Rate determined for such day plus the Applicable Margin.

              (b) Each ABR Loan shall bear interest at a rate per annum equal to
the ABR plus the Applicable Margin.

              (c) If all or a portion of the principal amount of any Loan or any
other amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum which is (i) in the case of overdue principal, the rate that
would otherwise be applicable thereto pursuant to the foregoing provisions of
this subsection plus 2% or (ii) in the case of any other overdue amount, the
Default Rate, in each case from the date of such non-payment until such amount
is paid in full (after as well as before judgment).

              (d) Interest shall be payable in arrears on each Interest Payment
Date; provided that interest accruing pursuant to paragraph (c) of this
subsection shall be payable on demand.

              2.14 Computation of Interest and Fees (a) Interest on ABR Loans
and facility fees shall be calculated on the basis of a 365- (or 366-, as the
case may be) day year for the

                                       30
<PAGE>

actual days elapsed. Interest on Eurodollar Loans shall be calculated on the
basis of a 360-day year for the actual days elapsed. The Administrative Agent
shall as soon as practicable notify the Borrower and the Lenders of each
determination of a Eurodollar Rate. The Administrative Agent shall as soon as
practicable notify the Borrower and the Lenders of the effective date and the
amount of each such change in interest rate.

              (b) Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to subsection 2.13(a).

              (c) If any Reference Lender's Revolving Credit Commitment shall
terminate or all its Loans shall be assigned for any reason whatsoever, such
Reference Lender shall, upon appointment of a new Reference Lender, cease to be
a Reference Lender and the Administrative Agent (after consultation with the
Lenders) and the Borrower shall designate another Lender as a Reference Lender
so that there shall at all times be at least two Reference Lenders. The
Administrative Agent shall notify the Lenders of any change in the Reference
Lenders.

              (d) Each Reference Lender shall use its best efforts to furnish
quotations of rates to the Administrative Agent as contemplated hereby. If any
of the Reference Lenders shall be unable or shall otherwise fail to supply such
rates to the Administrative Agent upon its request, the rate of interest shall,
subject to the provisions of subsection 2.15, be determined on the basis of the
quotations of the remaining Reference Lenders or Reference Lender.

              2.15 Inability to Determine Interest Rate. In the event that,
prior to the first day of any Interest Period, (a) the Administrative Agent
shall have determined (which determination shall, be conclusive and binding upon
the Borrower) that, by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
for such Interest Period, or (b) the Administrative Agent shall have received
notice from the Majority Lenders (which notice shall be conclusive and binding
on the Borrower) that the Eurodollar Rate determined or to be determined for
such Interest Period will not adequately and fairly reflect the cost to such
Lenders of making or maintaining their affected Loans during such Interest
Period, the Administrative Agent shall give telex, telecopy or telephonic notice
thereof (stating the reason therefor) to the Borrower and the Lenders as soon as
practicable. If such notice is given (i) any Eurodollar Loans requested to be
made on the first day of such Interest Period shall be made as ABR Loans, (ii)
any Loans that were to have been converted on the first day of such Interest
Period to Eurodollar Loans shall be converted to or continued as ABR Loans and
(iii) any outstanding Eurodollar Loans shall be converted, on the first day of
such Interest Period, to ABR Loans. Until such notice has been withdrawn by the
Administrative Agent or, in the case of any notice given by the Majority Lenders
pursuant to clause (b) of the first sentence of this subsection, by the Majority
Lenders, no further Eurodollar Loans shall be made or continued as such, nor
shall the Borrower have the right to convert Loans to Eurodollar Loans as the
case may be.

              2.16 Pro Rata Treatment and Payments. (a) Each borrowing of
Term Loans or Revolving Credit Loans by the Borrower from the Lenders hereunder,
each payment by the

                                       31
<PAGE>

Borrower on account of any facility fees hereunder and any reduction of the
Commitments of the Lenders shall be made pro rata according to the respective
Commitment Percentages of the Lenders. Each payment (including each prepayment)
by the Borrower on account of principal of and interest on Term Loans or
Revolving Credit Loans, as the case may be, shall be made pro rata according to
the respective outstanding principal amounts of such Loans then held by the
Lenders. All payments (including prepayments) to be made by the Borrower
hereunder and under the Notes on account of principal of and interest on the
Loans and facility fees shall be made without set off or counterclaim and shall
be made prior to 12:00 Noon, New York City time, on the due date thereof to the
Administrative Agent, for the account of the Lenders, at the Administrative
Agent's office specified in subsection 10.2, in Dollars and in immediately
available funds. The Administrative Agent shall distribute such payments to the
Lenders promptly upon receipt in like funds as received. All payments on account
of arrangement and annual administrative fees shall be made without set off or
counterclaim and shall be made prior to 12:00 Noon, New York City time, on the
due date thereof to the Administrative Agent, for its own account, at the
Administrative Agent's office specified in subsection 10.2, in Dollars and in
immediately available funds. Any other amount received by the Administrative
Agent which is payable to any Lender pursuant to the provisions of this
Agreement shall be distributed by the Administrative Agent to such Lender
promptly upon receipt in like funds as received. If any payment hereunder (other
than payments on the Eurodollar Loans) becomes due and payable on a day other
than a Business Day, such payment shall be extended to the next succeeding
Business Day, and, with respect to payments of principal, interest thereon shall
be payable at the then applicable rate during such extension. If any payment on
a Eurodollar Loan becomes due and payable on a day other than a Working Day, the
maturity thereof shall be extended to the next succeeding Working Day unless the
result of such extension would be to extend such payment into another calendar
month, in which event such payment shall be made on the immediately preceding
Working Day.

              (b) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a Borrowing Date that such Lender will not make
the amount that would constitute its Commitment Percentage of the borrowing on
such date available to the Administrative Agent, the Administrative Agent may
assume that such Lender has made such amount available to the Administrative
Agent on such Borrowing Date, and the Administrative Agent may, in reliance upon
such assumption, make available to the Borrower a corresponding amount. If such
amount is made available to the Administrative Agent by such Lender on a date
after such Borrowing Date, such Lender shall pay to the Administrative Agent on
demand an amount equal to the product of (i) the daily average Federal Funds
Effective Rate during such period as quoted by the Administrative Agent, times
(ii) the amount of such Lender's Commitment Percentage of such borrowing, times
(iii) a fraction, the numerator of which is the number of days that elapse from
and including such Borrowing Date to the date on which such Lender's Commitment
Percentage of such borrowing shall have become immediately available to the
Administrative Agent and the denominator of which is 360. A certificate of the
Administrative Agent submitted to any Lender with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error. If
such Lender's Commitment Percentage of such borrowing is not in fact made
available to the Administrative Agent by such Lender within three (3) Business
Days after such Borrowing Date, the Administrative Agent shall be entitled to
recover such amount with interest thereon at the rate per annum applicable to
ABR Loans hereunder, on demand, from the Borrower.

                                       32

              2.17 Illegality. Notwithstanding any other provision of the
Agreement, if any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, such Lender shall give
telex, or telecopy thereof to the Borrower and the Administrative Agent
(specifying the reason for such illegality) as soon as practicable and (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert ABR Loans to Eurodollar Loans shall
forthwith be canceled and (b) such Lender's Loans then outstanding as Eurodollar
Loans, if any, shall be converted automatically to ABR Loans on the respective
last days of the then current Interest Periods with respect to such Loans or
within such earlier period as required by law. If any such conversion of a
Eurodollar Loan occurs on a day which is not the last day of the then current
Interest Period with respect thereto, the Borrower shall pay to such Lender such
amounts, if any, as may be required pursuant to subsection 2.20 with respect to
such conversion.

              2.18 Requirements of Law. (a) In the event that any change in
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

              (i) shall subject any Lender to any tax of any kind whatsoever
         with respect to this Agreement, any Note or any Eurodollar Loan made by
         it, or change the basis of taxation of payments to such Lender in
         respect thereof (except for changes with respect to (i) "Taxes" as
         defined in subsection 2.19, (ii) rates of any taxes and (iii) taxes
         imposed on the overall net income of such Lender (and taxes imposed in
         lieu of taxes on overall net income) by the jurisdiction in which such
         Lender is organized or where its lending branch or a principal office
         is located or by any political subdivision or taxing authority within
         any of the foregoing, or by any other jurisdiction that are imposed
         solely as a result of a future, past or present connection between such
         jurisdiction and such Lender (other than a connection arising solely
         from the Lender having executed, delivered or performed its
         obligations, received payments under, or enforced, this Agreements and
         the Notes));

              (ii) shall impose, modify or hold applicable any reserve, special
         deposit, compulsory loan or similar requirement against assets held by,
         deposits or other liabilities in or for the account of, advances, loans
         or other extensions of credit by, or any other acquisition of funds by,
         any office of such Lender; or

              (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
under this Agreement and the Loan Documents in respect thereof, then, in any
such case, the Borrower shall promptly pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender for such increased cost
or reduced amount receivable; provided, however, that such Lender shall not be
entitled to receive any such additional amounts to the extent the same
constitute compensation for an increased cost or reduced amount receivable
incurred by such Lender which is payable, or which is applicable to any period,
more than ninety (90) days prior to the date the Borrower is

                                       33
<PAGE>

first notified by such Lender of the event which caused such increase or
reduction. A certificate as to any additional amounts payable pursuant to this
subsection, accompanied by an explanation of the basis thereof, submitted by
such Lender, through the Administrative Agent, to the Borrower shall be
conclusive in the absence of manifest error.

              (b) In the event that any Lender shall have determined that any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof does or shall have the effect of
reducing the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such change or compliance
(taking into consideration such Lender's or such corporation's policies with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time, after submission by such Lender to the Borrower (with a
copy to the Administrative Agent) of a written request therefor accompanied by
an explanation of the basis thereof (which shall be conclusive in the absence of
manifest error), the Borrower shall pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction; provided, however,
that such Lender shall not be entitled to receive any such additional amounts to
the extent the same constitute compensation for a reduction in rate of return
incurred more than ninety (90) days prior to the date the Borrower was first
notified hereunder of the change or compliance which caused such reduction.

              (c) The provisions of this subsection 2.18 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

              2.19 Taxes. (a) All payments made by the Borrower under this
Agreement and the 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, deductions, withholdings or similar
charges or fees, now or hereafter imposed, levied, collected, withheld or
assessed by any Governmental Authority, excluding, in the case of the
Administrative Agent and each Lender, (i) Taxes imposed on income (gross or
net), capital, net worth, profits or gain, and franchise taxes imposed on or in
respect of a Lender or the Administrative Agent by the jurisdiction (a) under
the laws of which such Lender or the Administrative Agent , as the case may be,
is organized, (b) in the case of a Lender, where its lending branch or a
principal place of business is located, or (c) in the case of the Administrative
Agent, where it performs its functions as the Administrative agent under this
Agreement, provided that, in the case of (b) and (c), such jurisdiction shall
not include any jurisdiction where a lending branch or principal place of
business is deemed to be located or where administrative functions are deemed to
be performed, in each case solely as a result of such Lender or the
Administrative Agent's participation in the transactions contemplated by this
Agreement, (ii) taxes imposed on income (gross or net), capital, net worth,
profits or gain and franchise taxes imposed on the Administrative Agent or such
Lender, as the case may be, as a result of a future, present or former
connection between the jurisdiction of the government or taxing authority
imposing such tax and the Administrative Agent or such Lender, as the case may
be (excluding a connection arising solely from the Administrative Agent or such
Lender having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement

                                       34
<PAGE>

or the Notes), (iii) any taxes that would not have been required to be withheld
if the Administrative Agent or such Lender timely furnished the Borrower a
United States Internal Revenue Service Form W-8BEN or W-8ECI or successor
applicable form as required by paragraph (b) below and (iv) any taxes that would
have not been required to be withheld but for the representation made in
paragraph (b)(i) below failing to be correct (all such non-excluded taxes,
levies, imposts, duties, charges, fees, deductions and withholdings being herein
called "Taxes"). The Borrower shall reimburse the Administrative Agent and each
Lender for the cost of any Taxes imposed on the Administrative Agent or such
Lender or on any payment made with respect to any Loan or Note or the making,
execution or enforcement thereof. If any Taxes are required to be withheld from
any amounts payable to the Administrative Agent or any Lender hereunder or under
the Notes, the amounts so payable to the Administrative Agent or such Lender
shall be increased to the extent necessary to yield to the Administrative Agent
or such Lender (after payment of all Taxes) the amount that such Lender or the
Administrative Agent, as the case may be, would have received had no such Taxes
been withheld. Whenever any Taxes are payable by the Borrower, on or before the
fourteenth day after payment, the Borrower shall send to the Administrative
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 Borrower
showing payment thereof, or if unavailable, other evidence of such payment. If
the Borrower fails to pay any Taxes when due to the appropriate taxing
authority, the Borrower shall indemnify the Administrative Agent and the Lenders
for any incremental taxes, interest or penalties that may become payable by the
Administrative Agent or any Lender as a result of any such failure. The
agreements in this subsection shall survive the termination of this 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 (i) represents to the Borrower that
either (x) as of the date it becomes a party to this Agreement it is entitled to
the benefits of an income tax convention between its country of residence and
the United States whereunder payments to it of amounts payable hereunder are
completely exempt from the withholding of United States Federal income tax so
long as the payments are not effectively connected with a United States
permanent establishment or (y) consistent with legal standards in effect on the
date it becomes a party to this Agreement (and assuming no change in such legal
standards) the income derived herefrom by it is and will be effectively
connected with the conduct of a United States trade or business and is subject
and will be subject to tax under Section 882 of the Code and (ii) agrees that it
will deliver to the Borrower and the Administrative Agent two duly completed
copies (or, at the request of the Borrower, such other number as may be required
under U.S. federal income tax law) of United States Internal Revenue Service
Form W-8BEN or W-8ECI or successor applicable form, as the case may be. Each
such Lender also agrees to deliver to the Borrower and the Administrative Agent
two further copies of the said Form W-8BEN or W-8ECI, or successor applicable
forms or other manner of certification, as the case may be, on or before the
date that any such form expires or becomes obsolete or after the occurrence of
any event requiring a change in the most recent form previously delivered by it
to the Borrower, and such extensions or renewals thereof as may reasonably be
requested by the Borrower or the Administrative Agent, unless in any such case
an event (including, without limitation, any change in treaty, law or
regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders such forms inapplicable or which would
prevent such Lender from duly completing and delivering

                                       35
<PAGE>

any such form with respect to it and such Lender so advises the Borrower and the
Administrative Agent.

              (c) In the event that an additional payment is made under
subsection 2.18 or this subsection 2.19 for the account of any Lender and such
Lender, in its sole discretion, determines that it has finally and irrevocably
received or been granted a tax credit, deduction or similar tax savings by
reason of, or calculated with reference to, the deduction or withholding giving
rise to such payment, such Lender shall, to the extent that it determines that
it can do so without prejudice to the retention of the amount of such credit,
deduction or similar tax savings, pay to the Borrower, such amount as such
Lender shall, in its reasonable opinion, have determined to be attributable to
such deduction or withholding and which will leave such Lender (after such
payment and after payment of any costs of obtaining such credit, deduction or
similar tax savings) in no worse position than it would have been in if the
Borrower had not been required to make such deduction or withholding. Nothing
herein contained shall interfere with the right of a Lender to arrange its tax
affairs in whatever manner it thinks fit and, in particular, a Lender shall not
be under any obligation to claim relief from corporate profits or similar tax
liability in respect of any such deduction or withholding in priority to any
other credit, deduction or similar tax savings available to them nor oblige any
Lender to disclose any information relating to its tax affairs or any
computations in respect thereof or require any Lender to do anything that would
prejudice its ability to benefit from any other credits, deductions or similar
tax savings to which it may be entitled.

              (d) If any Lender or the Administrative Agent is or becomes
eligible under any applicable law, regulation, treaty or other rule to a reduced
rate of taxation, or a complete exemption from withholding, with respect to
Taxes on payments made to it by the Borrower, such Lender or the Administrative
Agent, as the case may be, shall, upon the request, and at the cost and expense,
of the Borrower, complete and deliver from time to time any certificate, form or
other document demanded by the Borrower, the completion and delivery of which
are a precondition to obtaining the benefit of such reduced rate or exemption,
provided that the taking of such action by such Lender or Administrative Agent
would not, in the reasonable judgment of such Lender or the Administrative
Agent, be disadvantageous or prejudicial to such Lender or the Administrative
Agent or inconsistent with its internal policies or legal or regulatory
restrictions. For any period with respect to which a Lender or the
Administrative Agent, as the case may be, has failed to provide any such
certificate, form or other document demanded by the Borrower, such Lender or the
Administrative Agent, as the case may be, shall not be entitled to any payment
under subsection 2.18 or this subsection 2.19 in respect of any Taxes that would
not have been imposed but for such failure.

              (e) In the event that a Lender or the Administrative Agent
receives written communication from any Governmental Authority with respect to
an assessment or proposed assessment of any Taxes, such Lender or Administrative
Agent shall, within a reasonable period of time, notify the Borrower in writing
and shall provide a copy of such communication to the Borrower.

              2.20 Funding Indemnity. The Borrower agrees 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 Borrower in
payment when due of the principal amount of

                                       36
<PAGE>

or interest on any Eurodollar Loan, (b) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (c) default by the Borrower in making any
prepayment on the date specified for such prepayment in this Agreement or in the
notice of prepayment given by the Borrower pursuant to this Agreement, or (d)
the making of a payment or prepayment of Eurodollar Loans on a day which is not
the last day of an Interest Period with respect thereto, including, without
limitation, in each case, any such loss (other than non-receipt of the
Applicable Margin) or expense arising from the reemployment of funds obtained by
it or from fees payable to terminate the deposits from which such funds were
obtained. The provisions of this subsection 2.20 shall survive the termination
of this Agreement and the payment of the Loans and all other amounts payable
hereunder.

              2.21 Filing of Certificates; Change of Lending Office. If any
Lender claims additional amounts pursuant to subsection 2.18 or 2.19 such Lender
shall use reasonable efforts (consistent with legal and regulatory restrictions)
to file any certificate or document requested by the Borrower or to change the
jurisdiction of its applicable lending office if the making of such a filing or
the change in such office would avoid the need for, or reduce the amount of, any
such additional amounts which may thereafter accrue and would not, in the
reasonable determination of such Lender, be otherwise disadvantageous to such
Lender.

              2.22 Extension of Revolving Credit Termination Date.

              (a) The Borrower may, by written notice to the Administrative
Agent in the form of Exhibit E (each such notice being an "Extension Request")
given no earlier than sixty (60) days and no later than forty-five (45) days
prior to the then applicable Revolving Credit Termination Date, request that the
then applicable Revolving Credit Termination Date be extended to a date 364 days
after the then applicable Revolving Credit Termination Date. Such extension
shall be effective with respect to each Lender which, by written notice in the
form of Exhibit F (a "Continuation Notice") to Borrower and the Administrative
Agent given no earlier than forty-five (45) days and no later than thirty-five
(35) days prior to the then applicable Revolving Credit Termination Date,
consents, in its sole discretion, to such extension (each Lender giving a
Continuation Notice being referred to sometimes as a "Continuing Lender" and
each Lender other than a Continuing Lender being a "Non-Extending Lender");
provided however, that such extension shall be effective only if the aggregate
Revolving Loan Commitments of the Continuing Lenders are not less than 51% of
the Total Revolving Credit Commitment of the Lenders on the date of the
Extension Request. No Lender shall have any obligation to consent to any such
extension of the Revolving Credit Termination Date. If less than all of the
Lenders consent to any such request pursuant to subsection (a) of this Section
2.22, the Administrative Agent shall promptly so notify the Continuing Lenders,
and each Continuing Lender may, in its sole discretion, give written notice to
the Administrative Agent not later than ten (10) days after receipt of such
notice of the amount of the Non-Extending Lenders' Commitments for which it is
willing to accept an assignment. If the Continuing Lenders notify the
Administrative Agent that they are willing to accept assignments of Commitments
in an aggregate amount that exceeds the amount of the Commitments of the
Non-Extending Lenders, such Commitments shall be allocated among the Continuing
Lenders willing to accept such assignments in such amounts as are agreed between
the Borrower and the Administrative Agent. The Administrative Agent shall notify
each Lender of the receipt of an

                                       37
<PAGE>

Extension Request within three (3) Business Days after receipt thereof. The
Administrative Agent shall notify the Borrower and the Lenders no later than
fifteen (15) days prior to the applicable Revolving Credit Termination Date
whether the Administrative Agent has received Continuation Notices from Lenders
holding at least 51% of the Total Revolving Credit Commitment on the date of the
Extension Request.

              (b) The Revolving Credit Commitment of each Non-Extending Lender
shall terminate at the close of business on the Revolving Credit Termination
Date in effect prior to the delivery of such Extension Request without giving
any effect to such proposed extension, and on such Revolving Credit Termination
Date Borrower shall take one of the following three actions:

              (i) Replace the Non-Extending Lenders pursuant to Section 2.22(c);
         or

              (ii) Pay or cause to be paid to the Administrative Agent, for the
         account of the Non-Extending Lenders, an amount equal to the
         Non-Extending Lenders' Revolving Credit Loans, together with accrued
         but unpaid interest and fees thereon and all other amounts then payable
         hereunder; or

              (iii) By giving notice to the Administrative Agent, no later than
         three (3) days prior to the Revolving Credit Termination Date, elect
         not to extend the Revolving Credit Termination Date beyond the
         applicable Revolving Credit Termination Date and in this event the
         Borrower shall repay any amount of the Revolving Credit Loans then
         outstanding, together with accrued but unpaid interest and fees thereon
         and all other amounts then payable hereunder.

              (c) A Non-Extending Lender shall be obligated, at the request of
the Borrower to assign at any time prior to the close of business on the
Revolving Credit Termination Date applicable to such Non-Extending Lender all of
its rights (other than rights that would survive the termination of this
Agreement pursuant to subsection 10.5) and obligations hereunder to one or more
Lenders or other commercial lenders nominated by Borrower and willing to become
Lenders in place of such Non-Extending Lender (the "Replacement Lenders"). In
order to qualify as a Replacement Lender, a Lender or lender must satisfy all of
the requirements of this Agreement (including without limitation, the
Non-Extending Lender must satisfy the terms of subsection 10.6(c) and 10.6(e) as
if such Non-Extending Lender is actually a "transferor Lender" therein and, the
Replacement Lender must satisfy the terms of subsection 10.6(c) and 10.6(e) as
if such Replacement Lender is actually a "Purchasing Lender" therein). Such
obligation of the Non-Extending Lenders is subject to such Non-Extending Lenders
receiving payment in full from the Replacement Lenders (i) of the principal
amount of all Revolving Credit Loans owing to such Non-Extending Lender
immediately prior to an assignment to the Replacement Lenders and (ii) of all
accrued interest and fees and other amounts payable hereunder and then owing to
such Non-Extending Lender immediately prior to the assignment to the Replacement
Lenders. Upon such assignment, the Non-Extending Banks, and the Administrative
Agent shall make appropriate entries in the Register to reflect the foregoing.

                   SECTION 3. REPRESENTATIONS AND WARRANTIES

              To induce the Administrative Agent and the Lenders to enter into
this Agreement, and to induce the Lenders to make the Loans, the Borrower hereby
represents and warrants to the Administrative Agent and each Lender that:

              3.1 Financial Position. The consolidated balance sheet of the
Borrower and its Subsidiaries at December 31, 1999, and the related consolidated
statements of operations and cash flows for the fiscal year ended as of such
date, which statements have been audited by PriceWaterhouseCoopers, independent
certified public accountants, who delivered an unqualified opinion with respect
thereto, in each case present fairly in all material respects the consolidated
financial position of the Borrower and its Subsidiaries at such dates and the
results of its operations and its cash flows for the fiscal periods then ended.
Such financial statements, including the related schedules and notes thereto,
have been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as disclosed therein). All material liabilities of the
Borrower and its Subsidiaries, direct or indirect, absolute or contingent, as of
the date of this Agreement, are either disclosed in the balance sheet as at
December 31, 1999 or have been disclosed in writing by the Borrower to the
Lenders prior to the date of this Agreement.

              3.2 No Change. Since December 31, 1999, (a) there has been no
development or event which has had or could reasonably be expected to have a
Material Adverse Effect, and (b) no distributions have been declared, paid or
made to the Partners other than as permitted by subsection 6.4.

              3.3 Organization, Power and Status of the Borrower; Compliance
with Law; Partners and Partner Parents. The Borrower (i) is a limited
partnership duly formed, validly existing and in good standing under the laws of

Agreement to which the Borrower is a party, (iii) has all requisite partnership
power and authority, and the legal right, to own and operate the Project and to
carry on its business as now being conducted and as proposed to be conducted, to
perform each Primary Agreement to which the Borrower is a party and to take all
action as may be necessary to complete the transactions contemplated under this
Agreement, the Notes, each other Loan Document and each Primary Agreement to
which the Borrower is a party, (iv) is duly qualified, authorized to do business
and in good standing in the States of New York and Connecticut, and in each
other jurisdiction where the character of its properties or the nature of its
activities makes such qualification necessary and where failure so to qualify
could reasonably be expected to have a Material Adverse Effect and (v) is in
compliance with all Requirements of Law except to the extent that the failure to
comply therewith could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect. The Partners and their respective Partner Parents,
partnership interests, voting bloc and voting bloc interests as in effect on the
Closing Date are set forth on Schedule 1.

              3.4 Authorization; Enforceable Obligations. The Borrower has taken
all necessary partnership action to authorize the execution, delivery and
performance of this Agreement and the Notes, the borrowings contemplated to be
made by it hereunder, and each

                                       39
<PAGE>

Primary Agreement to which the Borrower is a party. This Agreement, the Notes to
which the Borrower is a party and the Primary Agreements to which the Borrower
is a party have been duly executed and delivered by the Borrower. This
Agreement, the Notes to which the Borrower is a party and the Primary Agreements
to which the Borrower is a party constitute legal, valid and binding obligations
of the Borrower enforceable against the Borrower in accordance with their
respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law).

              3.5 Subsidiaries; Business. As of the Closing Date, the Borrower
does not have any Subsidiaries other than the Operator and IGTS. Each Subsidiary
of the Borrower (i) is a duly organized and validly existing corporation or
other entity in good standing under the laws of the jurisdiction of its
organization and has the corporate or other organizational power and authority,
and the legal right, to own its property and assets and to transact the business
in which it is engaged, (ii) is duly qualified, authorized to do business and in
good standing in each jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary and where failure so
to qualify could reasonably be expected to have a Material Adverse Effect and
(iii) is in compliance with all Requirements of Law except to the extent that
the failure to comply therewith could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect. Neither the Borrower nor any of its
Subsidiaries is engaged in any business activity other than (i) the business
activities contemplated by the Primary Agreements and the Offering Memorandum
dated May 22, 2000 relating to the Securities issued on the Closing Date; (ii)
business activities associated with, or incidental to, the operation,
maintenance or expansion of the Pipeline or the storage of natural gas; (iii)
business activities associated with, or incidental to, (w) the processing or
shipping of natural gas, (x) the processing, shipping or storage of natural gas
liquids, (y) the installation and leasing or rental of fiber optic or similar
cable or (z) the construction or operation of facilities for the generation of
electricity using waste heat from the Pipeline's waste heat, in all such cases
related to the operation of the Pipeline; or (iv) business activities (including
investments) associated with, or intended to induce, the supply of gas for
transportation on the Pipeline or the consumption of gas transported by the
Pipeline (such business activities, collectively, "Permitted Business
Activities"), provided, that under no circumstance shall the Borrower engage or
invest in, or permit its Subsidiaries to engage or invest in, (A) any business
or activity related to the exploration and production of hydrocarbons or (B) any
business or activity described in clauses (iii) or (iv) above that would cause
the Consolidated Net Tangible Assets of the Borrower and its Subsidiaries
attributable to all their businesses and investments described in clauses (iii)
and (iv) above to exceed 10% of the amount of the Consolidated Net Tangible
Assets of the Borrower and its Subsidiaries attributable to all their businesses
and investments described in clauses (i) and (ii) above.

              3.6 No Legal Bar or Burdensome Restrictions. The execution,
delivery and performance of this Agreement, the Notes, the other Loan Documents
to which the Borrower is a party and the Primary Agreements to which the
Borrower is a party, and the borrowings hereunder and the use of the proceeds
thereof by the Borrower, will not result in a violation of any Requirement of
Law applicable to the Borrower (in the case of performance of the Primary
Agreements, which could reasonably be expected to have a Material Adverse
Effect) or result in a violation of (i) the Partnership Agreement, any Loan
Document or any Shipper Contract or (ii)

                                       40
<PAGE>

any other Contractual Obligation of the Borrower which could reasonably be
expected to have a Material Adverse Effect, and will not result in, or require,
the creation or imposition of any Lien on any of its properties or revenues
pursuant to any Requirement of Law applicable to the Borrower or the Partnership
Agreement or any Contractual Obligation of the Borrower. No Contractual
Obligation of the Borrower or any of its Subsidiaries has or is reasonably
expected to have a Material Adverse Effect.

              3.7 Governmental Approvals and Other Consents and Approvals. No
Governmental Approval or other consent or approval of third parties is required
in connection with the execution, delivery and performance of the Loan Documents
by the Borrower. No material Governmental Approval is required for the Borrower
to own and operate the Project, to transport up to 987 MDth/d of natural gas
through the Pipeline and to carry on its business as now being conducted and as
proposed to be conducted by it, or for the Borrower, or the Operator or
Tennessee (in their capacities as operators of the Pipeline), to participate in
the transactions contemplated by this Agreement, the other Loan Documents and
the Primary Agreements or to perform their obligations under the Primary
Agreements to which they are parties, except for those Governmental Approvals
which have been duly obtained or made, have been accepted by the Borrower, are
in full force and effect, are not the subject of any pending judicial or
administrative proceedings, and if the applicable statute, rule or regulation
provides for a fixed period for judicial or administrative appeal or review
thereof, such periods have expired and no petition for administrative or
judicial appeal or review has been filed other than those Governmental Approvals
and other consents or approvals of third parties the failure of which,
individually or collectively, would not reasonably be expected to have a
material Adverse Effect.

              3.8 No Material Litigation. Except as described on Schedule 4, (a)
no litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority to which the Borrower or any of its Subsidiaries is a

to be observed or performed by it under the Operating Agreement, which in any
case or in the aggregate could reasonably be expected to have a Material Adverse
Effect. As of the Closing Date, to the knowledge of the Borrower, (i) no party
to any Primary Agreement is in breach of any condition, covenant or obligation
to be observed or performed by such party thereunder, which in any case or in

              3.10 Ownership of Property; Liens. The Borrower and each of its
Subsidiaries have good and marketable title in fee simple to or have valid
rights to lease or otherwise use, all items of real and personal property which
are material to their respective businesses as currently conducted and as
proposed to be conducted except where the failure to have such good title could
not reasonably be expected to have a Material Adverse Effect, and all of the
property (real and personal) of the Borrower and its Subsidiaries is free and
clear of all Liens except (i) any Lien which does not materially interfere with
the use made and proposed to be made of such property by the Borrower and its
Subsidiaries, (ii) any Lien which could not reasonably be expected to have a
Material Adverse Effect or (iii) any Lien that is permitted by subsection 6.2
hereof. The Borrower has title in fee simple to, or a valid leasehold interest
in, or a valid right of way and easement or license over, all real property
required for the operation and maintenance of the Pipeline. All recordings,
filings and other actions that are necessary or appropriate in order to create,
perfect, preserve and protect the right, title, estate and interest of the
Borrower in and to such real property have been duly made or taken, and all
fees, taxes and other charges relating to such recordings, filings and other
actions have been, or at the time of each such recording, filing or other action
will be, paid by or on behalf of the Borrower.

              3.11 Taxes. Each of the Borrower and its Subsidiaries has filed or
caused to be filed all material federal, state, local, foreign income and

or on any assessments made against it or any of its property and all other
material taxes imposed on it or any of its property by any Governmental
Authority (other than any material taxes the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower the failure of which to file or to pay could not
reasonably be expected to have a Material Adverse Effect); on the Closing Date
no tax Lien has been filed that remains unsatisfied (other than any such Lien
for taxes that are not yet delinquent or that are being contested in good faith
by appropriate proceedings), and, to the knowledge of the Borrower, no claim is
being asserted, with respect to any such tax.

              3.12 Federal Regulations. No part of the proceeds of any Loans
will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U or for any
purpose which violates the provisions of the Regulations of the Board.

              3.13 ERISA. Except where such noncompliance could not reasonably
be expected to have a Material Adverse Effect, each Plan is in compliance in all
material respects with applicable law, including ERISA and the Code. Except for
such liabilities that could not reasonably be expected to have a Material
Adverse Effect, the Borrower and each Commonly Controlled Entity have not
incurred and do not expect to incur any liability under Title IV of ERISA with
respect to the termination of or withdrawal from any pension plan (including any
Multiemployer Plan). Except where such nonqualification could not reasonably be
expected to have a Material Adverse Effect, each Plan that is intended to be
qualified under Section 401(a) of the Code is so qualified in all material
respects and nothing has occurred, whether by action or by failure to act, which
could reasonably be expected to cause the loss of such qualification.

There are no services, materials or rights required for the operation or
maintenance of the Pipeline in accordance with the Primary Agreements, other

transportation Shipper Contract, which has been executed and delivered
(including all exhibits and schedules referred to therein or delivered pursuant

the Borrower that is not disclosed in the documents delivered to the

businesses, which insurance is in amounts and insures against such losses and
risks as are adequate to protect the Borrower and its Subsidiaries and their
respective businesses except where the failure to have such insurance could not
reasonably be expected to have a Material Adverse Effect. Neither the Borrower
nor any of its Subsidiaries has received notice from any insurer or agent of
such insurer that capital improvements or other expenditures are required or
necessary to be made in order to continue

                                       44

expected to have a Material Adverse Effect.

              obligations of the Borrower pursuant to such agreements, in any
              case incurred in connection with the disposition of any business
              or assets (other than guarantees of Indebtedness incurred by any
              Person acquiring all or any portion of such business or assets for
              the purpose of financing such acquisition), in a principal amount
              not to exceed the gross proceeds actually received by the Borrower
              in connection with such disposition;

                  (4) Indebtedness of the Borrower, to the extent the net
              proceeds thereof are promptly deposited to defease the Securities
              in accordance with the terms of the Senior Indenture on terms no
              more favorable than those contained in the Indenture and in

                  (5) Affiliate Subordinated Debt;

                  (6) Indebtedness of the Borrower incurred to refinance
              Indebtedness existing from time to time, provided such
              Indebtedness is in a principal amount no

                                       52
<PAGE>

              greater than the Indebtedness being repaid (excluding fees,
              including any consent fees, payable in connection with the
              issuance of any refinancing indebtedness), has a longer final
              maturity and greater average life than the Indebtedness being
              repaid and, except in the case of Indebtedness incurred to
              refinance a series of Securities under the Senior Indenture,
              satisfies the requirement set forth under clause (i) above;

                  (7) Indebtedness of $10 million incurred from time to time

              5.6 hereof; and

                  (8) Indebtedness of the Borrower (in addition to Indebtedness
              permitted under clauses (1) through (7) above) in an aggregate
              principal amount outstanding at any time (together with
              refinancings thereof) not to exceed $35 million; provided that at
              the time the Indebtedness is incurred, the Borrower satisfies the
              requirement set forth under clauses (ii) and (iii) above.

              Notwithstanding any of the foregoing, the maximum amount of
              Indebtedness that the Borrower may incur pursuant to this clause
              (d) shall not be deemed to be exceeded, with respect to any
              outstanding Indebtedness, due solely to the result of fluctuations
              in interest rates designated in any Interest Rate Agreement or in
              the exchange rates of currencies designated in any Currency
              Agreement.

              For purposes of determining any particular amount of Indebtedness
              under this clause (d), guarantees, Liens or obligations with
              respect to letters of credit supporting Indebtedness otherwise
              included in the determination of such particular amount shall not
              be included. For the purposes of clarification and not limitation,
              any Lien incurred by the Borrower or any of its Subsidiaries shall
              not be a separate incurrence of Indebtedness. For purposes of
              determining compliance with this clause (d), in the event that an
              item of Indebtedness meets the criteria of more than one of the
              types of Indebtedness described in the above clauses, the
              Borrower, in its sole discretion, shall classify, and from time to
              time may reclassify, such item of Indebtedness and only be
              required to include the amount and type of such Indebtedness in
              one of such clauses; provided, however, that the Borrower may only
              reclassify Affiliate Subordinated Debt, if, at the time of such
              reclassification, the Borrower would be permitted to make a
              Distribution in the amount of such reclassified Affiliate
              Subordinated Debt pursuant to subsection 6.3. Neither the accrual
              of interest nor the accretion of original issue discount shall be
              deemed to be an incurrence of indebtedness.

              6.2 Limitation on Liens. Create, incur, assume or suffer to exist
any Lien upon any of its property, assets or revenues, whether now owned or
hereafter acquired, except for:

              (a) a Lien which ratably and equally secures all of the Senior
       Debt;

              (b) a Lien that is created in favor of a governmental entity,
       mechanic, materialman or lessor in the ordinary course of business and

       overdue for a period of more than 30 days, but not in any event Liens in
       favor of a lessor in a sale-leaseback transaction;

              (c) a Lien that is the result of a court judgment as to which all
       rights of the appeal have not terminated and is bonded or pledged or the
       enforcement of which will not have a Material Adverse Effect.

              (d) Liens extending, renewing or replacing Permitted Liens (other
       than any additional Lien described in clause (h) below);

              (e) Liens securing pledges or deposits under workers'
       compensation, unemployment insurance and other social security
       legislation;

              (f) Liens consisting of easements, rights-of-way and other similar
       encumbrances and does not interfere with the business or operations of
       the Borrower and its Subsidiaries; (g) a Lien granted by a Subsidiary
       upon any of such Subsidiary's assets to secure Non-Recourse Indebtedness
       of such Subsidiary; and

              (h) any additional Lien, provided that the Indebtedness secured by
       the Lien, plus all other Indebtedness secured by Liens (including
       Indebtedness for capitalized lease obligations but excluding Indebtedness
       secured by Liens otherwise permitted by clauses (a) through (g) above)
       plus all leases under sale-leaseback transactions which the Borrower has
       not elected to treat as an Asset Sale, does not exceed 3% of Total
       Capitalization of the Borrower.

              6.3 Limitation on Distributions. Declare, pay or make any
Distribution, either directly or indirectly, whether in cash or property or in
obligations of the Borrower; provided that, the Borrower may make Distributions
if:

              (a) no Default or Event of Default shall have occurred and be
       continuing, or would occur as a result of declaring or making such
       Distribution;

              (b) the ratio of Indebtedness to Total Capitalization after giving
       effect to such intended Distribution does not exceed 75%;

              (c) (i) the Debt Service Coverage Ratio of the Borrower for the
       last four calendar quarters taken as a whole prior to such intended
       Distribution is at least 1.25 to 1 and (ii) if the then current rating of
       the Securities is below "BBB+" from S&P or below "A3" from Moody's, the
       Projected Debt Service Coverage Ratio of the Borrower for the next four
       calendar quarters from the date of such Distribution is expected to be at
       least 1.25 to 1, both as certified by a Responsible Officer of the
       Borrower in an Officer's Certificate delivered to the Administrative
       Agent, provided, that, this Section 6.3(c)(ii) shall not apply, in the
       case of any Distribution made in the twelve months prior to the Final
       Maturity Date of Non-Amortizing Securities if, after making such
       Distribution, the cash on hand of the Borrower and the expected Operating
       Cash Flow for the period commencing on the date of such Distribution and
       ending on the Final Maturity Date of

                                       54
<PAGE>

       such Non-Amortizing Securities will be sufficient to enable the Borrower
       to make such payments of principal and interest due on such Securities on
       such Final Maturity Date as certified by the Borrower in an Officer's
       Certificate delivered to the Administrative Agent; and

       on hand of the Borrower plus (ii) the expected Operating Cash Flow for
       the period commencing on the date of such Distribution and ending on the
       next scheduled payment date of the Securities (excluding expected
       Operating Cash Flow and cash on hand, if any, relied on in connection
       with satisfying the requirements of the proviso of Section 6.3(c)(ii)
       above) plus (iii) the expected Available Revolving Credit Commitment on
       such payment date will be sufficient to enable the Borrower to make all
       payments of principal and interest due on the Loans, the Securities and
       any other Senior Debt at any time on or after the date of such
       Distribution to and including such scheduled payment date of the
       Securities, excluding any principal and interest due on the Final
       Maturity Date of Non-Amortizing Securities payment of which will be
       satisfied by expected Operating Cash Flow and cash on hand pursuant to
       the proviso to Section 6.3(c)(ii) above, as certified by a Responsible

       final, non-appealable order authorizing the abandonment of any material
       component of the Project (or deeming such a material component
       abandoned), which partial abandonment would result in a reduction in

then,

              (1) Borrower Bankruptcy. If such event is an Event of Default
       specified in subsection (f) of this Section 7, automatically the
       Commitments immediately shall terminate and the Loans (with accrued
       interest thereon) and all other amounts owing by the Borrower under this
       Agreement and the Notes immediately shall become due and payable; and

              (2) Other Events of Default. If such event is an Event of Default
       other than one specified in paragraph (1) above, either or both of the
       following actions may be taken: (i) with the consent of the Majority
       Lenders the Administrative Agent may or upon the request of the Majority

<PAGE>

       Borrower, declare the Commitments to be terminated, whereupon the
       Commitments immediately shall terminate; and (ii) with the consent of the
       Majority Lenders the Administrative Agent may, or upon the request of the
       Majority Lenders the Administrative Agent shall, by notice to the
       Borrower, declare the Loans (with accrued interest thereon) and all other
       amounts owing under this Agreement and the other Loan Documents to be due

Notwithstanding any of the foregoing, any Partner shall have the right, but not
the obligation, to cure any payment default in clauses (a), (b), (g) or (h) of
this Section 7 within the respective grace period set forth in such clauses,
and, if such payment is cured, such payment default shall not constitute an
Event of Default.

Except as expressly provided above in this Section 7, presentment, demand,
protest and all other notices of any kind are hereby expressly waived.

                            SECTION 8. NON-RECOURSE

              None of the Partners or the Partner Parents shall be personally
liable for any obligation of the Borrower under this Agreement, or any other
Loan Document or for the performance of any obligation of the Borrower hereunder
or thereunder or breach of any representation or warranty made by the Borrower.
The exclusive recourse of the Administrative Agent and the Lenders for
satisfaction of the obligations of the Borrower under this Agreement, or any
other Loan Document shall be against the Borrower and its assets (and not
against any assets or property of the Partners or the Partner Parents). In the
event that any default occurs in connection with the obligations of the Borrower
under this Agreement, or any other Loan Document, no action shall be brought
against the Partners or the Partner Parents if such action is predicated solely
upon such Person's direct or indirect ownership interest in the Borrower. In the
event of foreclosure or other sale or disposition of properties, no judgment for
any deficiency upon the obligations of the Borrower under this Agreement, or any
other Loan Document shall be obtainable by the Administrative Agent or any
Lender against the Partners or the Partner Parents.

                      SECTION 9. THE ADMINISTRATIVE AGENT

              9.1 Appointment. Each Lender hereby irrevocably designates and
appoints Chase as its agent under this Agreement and the other Loan Documents,
and each Lender irrevocably authorizes Chase, as the agent for such Lender, to
take such action on its behalf under the provisions of this Agreement and the
other Loan Documents and to exercise such powers and perform such duties as are
expressly delegated to the Administrative Agent by the terms of this Agreement
and the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this

                                       60
<PAGE>

Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Neither the Syndication Agent nor the Documentation Agent,
in such capacities, shall have any duties or responsibilities under this
Agreement or any fiduciary relationship with the Administrative Agent or any
Lender, and no implied covenants, functions, responsibilities, duties or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Syndication Agent or the Documentation Agent in such
capacity hereunder.

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

        9.3  Exculpatory Provisions. Neither the Administrative Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except for its or such Person's own gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by the Borrower or any
officer thereof contained in this Agreement or any other Loan Document or any
Primary Agreement or in the Information Memorandum or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document or any Primary Agreement or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Documents or any Primary Agreement or for any failure of the
Borrower to perform its obligations hereunder or thereunder. The Administrative
Agent shall not be under any obligation to any Lender to ascertain or to inquire
as to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document or any Primary
Agreement, or to inspect the properties, books or records of the Borrower.

        9.4  Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely, and shall be fully protected in relying, upon any 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
Borrower), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Note as the owner thereof for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority 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
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the other Loan Documents in
accordance with a request of the Majority Lenders, and such request

                                       61
<PAGE>

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

        9.5  Notice of Default. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Administrative Agent has received notice from a Lender or
the Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Lenders. The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Majority Lenders; provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such-action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Lenders.

        9.6  Non-Reliance on Administrative Agent and Other Lenders. Each Lender
expressly acknowledges that neither the Administrative 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 Administrative
Agent hereafter taken, including any review of the affairs of the Borrower,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of the Borrower, the Partners, the Partner Parents and the
Shippers and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Lender also represents that it will, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrower, the Partners, the Partner Parents, the Shippers and any other Persons.
Except for notices, reports and other documents expressly required to be
furnished to the Lenders by the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
property, condition (financial or other), prospects or creditworthiness of the
Borrower, the Partners, the Partner Parents, the Shippers or any other Person
which may come into the possession of the Administrative Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

        9.7  Indemnification. The Lenders agree to indemnify the Administrative
Agent in its capacity as such and its directors, officers, employees and agents
(to the extent not reimbursed by the Borrower and without limiting the
obligation of the Borrower to do so), severally according to their respective
Commitment Percentages, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind whatsoever which may at any time (including, without
limitation, at any time following the payment of the Loans and other amounts
payable hereunder) be imposed

                                       62
<PAGE>

on, incurred by or asserted against the Administrative Agent in any way relating
to or arising out of this Agreement, any of the other Loan Documents or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the Administrative
Agent's gross negligence or willful misconduct. The agreements in this
subsection shall survive the payment of the Loans and all other amounts payable
hereunder.

        9.8  Administrative Agent in Its Individual Capacity. The Administrative
Agent and its Affiliates may make loans to, accept deposits from and generally
engage in any kind of business with the Borrower, the Partners and the Partner
Parents and their respective Affiliates as though the Administrative Agent were
not the Administrative Agent hereunder and under the other Loan Documents. With
respect to its Loans made or renewed by it and any Note issued to it, the
Administrative Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any Lender and may exercise the same as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders" shall
include the Administrative Agent in its individual capacity.

        9.9  Successor Administrative Agent. Subject to the appointment of a
successor Administrative Agent as provided below, Chase (and any successor
thereto as Administrative Agent) may resign as Administrative Agent under this
Agreement by giving at least thirty (30) days' notice thereof to the Lenders and
the Borrower. Upon any such resignation, the Majority Lenders shall appoint from
among the Lenders a successor Administrative Agent for the Lenders, which
successor Administrative Agent shall be reasonably acceptable to the Borrower
(unless an Event of Default has occurred and is continuing). If no successor
Administrative Agent shall have been appointed by the Majority Lenders and shall
have accepted such appointment within thirty (30) days after the resigning
Administrative Agent's giving of notice of resignation, then the resigning
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a Lender or any other lender with an office
in New York, New York having a combined capital and surplus of not less than
$500,000,000 and which shall be reasonably acceptable to the Borrower. Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning Administrative Agent, and the resigning Administrative Agent
shall be discharged from its duties and obligations hereunder, without any other
or further act or deed on the part of the resigning Administrative Agent or any
of the parties to this Agreement or any holders of the Notes. After any
resigning Administrative Agent shall cease to be the Administrative Agent
hereunder, the provisions of this subsection 9.9 shall continue in effect for
its benefit in respect of any actions taken or omitted to be taken by it while
it was acting as Administrative Agent under this Agreement and the other Loan
Documents.

                           SECTION 10. MISCELLANEOUS

        10.1 Amendments and Waivers. Neither this Agreement, any Note, nor any
term hereof or thereof may be amended, supplemented or modified except in
accordance with the provisions of this subsection. With the written consent of
the Majority Lenders, the Administrative Agent and the Borrower may, from time
to time, enter into written amendments, supplements or modifications hereto and
to the Notes for the purpose of adding any provisions to this Agreement or the
Notes or changing in any manner the rights of the Lenders or of the Borrower
hereunder or thereunder or waiving, on such terms and conditions as may be
specified in such instrument, any of the requirements of this Agreement or the
Notes on any Default or Event of Default and its consequences; provided,
however, that no such waiver and no such amendment, supplement or modification
shall (a) reduce the amount or extend the maturity of any Note or any
installment thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any fee payable to any Lender hereunder, or change
any Lender's Commitment Percentage, in each case without the consent of the
Lender affected thereby, or (b) amend, modify or waive any provision of this
subsection or reduce the percentage specified in the definition of Majority
Lenders, or consent to the assignment or transfer by the Borrower of any of its
rights and obligations under this Agreement in each case without the written
consent of all the Lenders, or (c) amend, modify or waive any provision of
Section 9 without the written consent of the then Administrative Agent, or (d)
amend, modify or waive any provision of this Agreement affecting the rights or
obligations of the Administrative Agent, without the written consent of the
Administrative Agent, as the case may be. Any such waiver and any such
amendment, supplement or modification shall apply equally to each of the Lenders
and shall be binding upon the Borrower, the Lenders, the Administrative Agent,
and all future holders of the Notes. In the case of any waiver, the Borrower,
the Lenders, and the Administrative Agent shall be restored to their former
position and rights hereunder and under the outstanding Notes and any Default or
Event of Default waived shall be deemed to be cured and not continuing; but no
such waiver shall extend to any subsequent or other Default or Event of Default,
or impair any right consequent thereon.

including, without limitation, any of the foregoing relating to the violation

(ii) resulting from injury to or death of any person whomsoever, and damage to
or loss or destruction of any property whatsoever, which in any way arises in
connection with, incidental to or caused by the operation of the Project or any
activity on or near the Project, and (iii) in any way relating to or arising out
of the Project or any part thereof, or the manufacture, financing, construction,

preparation, installation, storage, maintenance, repair, transfer of title,
abandonment, possession, rental, use, operation, condition, sale, return,

or willful misconduct of such indemnified party. Each Person claiming any right
to indemnity under clause (d) of the next preceding sentence by reason of the
institution of any action against such Person shall notify the Borrower thereof
and shall consult with the Borrower from time to time in connection with the
defense of such action. The agreements in this subsection shall survive
repayment of the Loans and all other amounts payable hereunder.

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

        (b)  Any Lender may, in the ordinary course of its commercial lending
business and in accordance with applicable law, at any time sell to one or more
banks or other entities ("Participants") participating interests in any Loan
owing to such Lender, any Note held by such Lender, any Commitment of such
Lender or any other interest of such Lender hereunder. In the event of any such
sale by a Lender of participating interests to a Participant, such Lender's
obligations under this Agreement to the other parties to this Agreement shall
remain unchanged, such Lender shall remain solely responsible for the
performance thereof, such Lender shall remain the holder of any such Note for
all purposes under this Agreement and the other Loan Documents, and the Borrower
and the Administrative Agent shall continue to deal solely and

                                       66
<PAGE>

directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. The Borrower also
agrees that each Participant shall be entitled to the benefits of subsections
2.18, 2.19, 2.20 and 10.5(d)(ii) and (iii) with respect to its participation in
the Commitments and the Loans outstanding from time to time; provided, that (i)
no Participant shall be entitled to receive any greater amount pursuant to such
subsections than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor Lender
to such Participant had no such transfer occurred, (ii) no Participant shall be
entitled to any indemnification by the Borrower to the extent that, at the time
of its purchase of a participating interest in the Loans, it cannot make the
representation specified in the first sentence of subsection 2.19(b) and (iii)
each Participant shall be bound by the confidentiality provisions contained in
subsection 10.11. In no event shall a Lender that sells a participating interest
be obligated to the Participant to take or refrain from taking any action
hereunder or under any of the other Loan Documents except that such Lender may
agree that it will not, without the consent of such Participant, agree to (A)
increase or extend the term of the Commitments of such Lender, (B) reduce the
principal of, or interest payable on, the Loans of such Lender or any fees or
other amounts payable to such Lender hereunder, (C) postpone the date fixed for
any payment of the principal of, or interest on, the Loans of such Lender or
other amounts payable to such Lender hereunder, or (D) change the percentage of
the Commitments or of the aggregate unpaid principal amount of the Loans which
shall be required for the Lenders or any of them to take any action hereunder.

        (c)  Any Lender may (or in accordance with subsection 2.22(c), must), in
the ordinary course of its commercial lending business and in accordance with
applicable law, at any time sell to any other Lender or to any Qualified
Financial Institution (all such purchasers, collectively, "Purchasing Lenders")
all of its rights and obligations under this Agreement and the Note held by it
(or any part of such rights and obligations; provided that, after giving effect
to such sale, such transferor Lender and such Purchasing Lender each has
Commitments and/or Loans aggregating not less than $5,000,000 pursuant to a
Commitment and Loan Transfer Supplement, substantially in the form of Exhibit C
(a "Commitment Transfer Supplement"), executed by such Purchasing Lender, such
transferor Lender (and, in the case of a Purchasing Lender that is not then a
Lender or a Qualified Financial Institution under clause (a) of the definition
thereof in subsection 1.1, by the Borrower and the Administrative Agent) and
delivered to the Administrative Agent for its acceptance and recording in the
Register (as hereinafter defined). Upon such execution, delivery, acceptance and
recording, from and after the Transfer Effective Date determined pursuant to
such Commitment Transfer Supplement, (x) the Purchasing Lender thereunder shall
be a party hereto and shall be bound by the provisions hereto and, to the extent
provided in such Commitment Transfer Supplement, shall have the rights and
obligations of a Lender hereunder, with its Commitments as set forth in such
Commitment Transfer Supplement, and (y) the transferor Lender thereunder shall,
to the extent provided in such Commitment Transfer Supplement, be released from
its obligations under this Agreement (and, in the case of a Commitment Transfer
Supplement covering all or the remaining portion of a transferor Lender's rights
and obligations under this Agreement, such transferor Lender shall cease to be a
party hereto). Such Commitment Transfer Supplement shall be deemed to amend this
Agreement to the extent, and only to the extent, necessary to reflect the
addition of such Purchasing Lender as a Lender party hereto and the resulting
adjustment of Commitment Percentages and Commitments arising from the purchase
by such Purchasing Lender of all or a portion of the rights and obligations of
such transferor Lender under this

                                       67
<PAGE>

Agreement and the Note held by it. On the Transfer Effective Date determined
pursuant to such Commitment Transfer Supplement, or as soon as possible
thereafter, the Borrower, at its own expense, shall execute and deliver to the
Administrative Agent in exchange for the Note held by the transferor Lender
(which Note shall be surrendered to the Administrative Agent for delivery to the
Borrower), a new Note to the order of such Purchasing Lender reflecting the
respective Commitments and outstanding Loans obtained by it pursuant to such
Commitment Transfer Supplement and, if the transferor Lender has retained
Commitments and Loans hereunder, a new Note to the order of the transferor
Lender reflecting the respective commitments and outstanding Loans retained by
it hereunder. Such new Notes shall be dated the date which is the first day of
the first Interest Period then in effect for which interest has not been paid
and shall otherwise be in the form of the Note replaced thereby. The Note
surrendered by the transferor Lender shall be returned by the Administrative
Agent to the Borrower marked "canceled".

        (d)  The Administrative Agent shall maintain at its address referred to
in subsection 10.2 a copy of each Commitment Transfer Supplement delivered to it
and a register (the "Register") for the recordation of the names and addresses
of the Lenders and the Commitments of, and principal amount of the Loans owing
to, each Lender from time to time. The entries in the Register shall be
conclusive, in the absence of manifest error, and the Borrower, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register as the owner of the Loans recorded therein for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

        (e)  Upon its receipt of a Commitment Transfer Supplement executed by a
transferor Lender and Purchasing Lender (and, in the case of a Purchasing Lender
that is not then a Lender or a Qualified Financial Institution under clause (a)
of the definition thereof in subsection 1.1, by the Borrower and the
Administrative Agent), together with payment to the Administrative Agent by the
transferor Lender of a registration and processing fee of $2,000, the
Administrative Agent shall (i) promptly accept such Commitment Transfer
Supplement and (ii) on the Transfer Effective Date determined pursuant thereto
record the information contained therein in the Register and give notice of such
acceptance and recordation to the Lenders and the Borrower.

        (f)  The Borrower authorizes each Lender to disclose to any Participant
or Purchasing Lender (each, a "Transferee") and any prospective Transferee any
and all financial and other information in such Lender's possession concerning
the Borrower and its Partners and their respective Affiliates and the Project
which has been delivered to such Lender by or on behalf of the Borrower pursuant
to this Agreement or which has been delivered to such Lender by or on behalf of
the Borrower in connection with such Lender's evaluation of the Project and its
credit evaluation of the Borrower and its Partners and their respective
Affiliates prior to becoming a party to this Agreement; provided that such
Transferee or prospective Transferee agrees to be bound by the confidentiality
provisions contained in subsection 10.11.

        (g)  If, pursuant to this subsection, any interest in this Agreement or
any Note is transferred to any Purchasing Lender which is organized under the
laws of any jurisdiction other than the United States or any state thereof, the
transferor Lender shall cause such Purchasing Lender, concurrently with the
effectiveness of such transfer, (i) to represent to the

                                       68
<PAGE>

transferor Lender (for the benefit of the transferor Lender, the Administrative
Agent and the Borrower) that under applicable law and treaties then in effect no
United States federal taxes will be required to be withheld by the
Administrative Agent, the Borrower or the transferor Lender with respect to any
payments to be made to such Purchasing Lender in respect of the Loans, (ii) to
furnish to the Administrative Agent and the Borrower either U.S. Internal
Revenue Service Form W-8BEN or W-8ECI (wherein such Purchasing Lender claims
entitlement to complete exemption from U.S. federal withholding tax on all
interest payments hereunder) and (iii) to agree (for the benefit of the
transferor Lender, the Administrative Agent and the Borrower) to provide the
Administrative Agent and the Borrower a new Form W-8BEN or W-8ECI upon the
expiration or obsolescence of any previously delivered form and comparable
statements in accordance with applicable U.S. laws and regulations and
amendments duly executed and completed by such Transferee, unless an event
(including, without limitation, any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders such forms inapplicable or which would prevent such
Purchasing Lender from duly completing and delivering any such forms with
respect to it and such Purchasing Lender so advises the Borrower and the
Administrative Agent.

        (h)  Nothing herein shall prohibit any Lender from pledging or assigning
any Note to any Federal Reserve Bank in accordance with applicable law.

        (i)  In the event any Lender demands payment of additional amounts
pursuant to subsection 2.18 or 2.19, the Borrower, at its expense, at any time
within three (3) months after such demand, may, so long as no Default or Event
of Default shall have occurred and be continuing, require such Lender to sell in
accordance with the foregoing provisions of this subsection 10.6, at par plus
accrued interest, without recourse or warranty, all its rights and obligations
hereunder (including its Commitments and the Loans at the time owing to it and
the Note held by it) to a Qualified Financial Institution specified by the
Borrower; provided that (A) such assignment shall not conflict with or violate
any law, rule or regulation or order of any court or other Governmental
Authority, and (B) the Borrower shall have paid to the assigning Lender all
amounts (other than interest) accrued and owing hereunder to it (including,
without limitation, amounts owing pursuant to subsections 2.18, 2.19 and 2.20).
Notwithstanding anything set forth above in this paragraph (i) to the contrary,
the Borrower shall not be entitled to require an assignment under this paragraph
(i) with respect to any Lender demanding payment under subsection 2.18 or 2.19
if, prior to any such requirement by the Borrower, such Lender shall have
changed its lending office so as to eliminate the incurrence of the costs in
respect of which such payment was demanded.

        10.7 Adjustments; Set-off.
             --------------------

        (a)  If any Lender (a "benefitted Lender") shall at any time receive any
payment of all or part of its Loans, or interest thereon, or receive any
collateral in respect thereof (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in subsection 7(f),
or otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of such other Lender's Loans,
or interest thereon (other than Chase (in the case of Swingline Loans) or a
Non-Extending Lender pursuant to Section 2.22), such benefitted Lender shall
purchase for cash from the other Lenders such portion of each such other
Lender's Loans, or shall provide such other Lenders with the

                                       69
<PAGE>

benefits of any such collateral, or the proceeds thereof, as shall be necessary
to cause such benefitted Lender to share the excess payment or the benefits of
such collateral or proceeds ratably with each of the Lenders; provided, however,
that if all or any portion of such excess payment or benefits is thereafter
recovered from such benefitted Lender, such purchase shall be rescinded, and the
purchase price and benefits returned, to the extent of such recovery, but
without interest. The Borrower agrees that each Lender so purchasing a portion
of another Lender's Loans may exercise all rights of payment (including, without
limitation, rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

        (b)  In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrower, any
such notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon any amount becoming due and payable by the Borrower
hereunder or under the Notes (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender to or for the credit or the
account of the Borrower, and whether or not such Lender is otherwise fully
secured. Each Lender agrees promptly to notify the Borrower and the
Administrative Agent after any such set-off and application made by such Lender;
provided that the failure to give such notice shall not affect the validity of
such set-off and application.

        10.8 Counterparts. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. A set of the copies of this Agreement signed by all the parties
shall be lodged with the Borrower and the Administrative Agent.

        10.9 Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

        10.10 Integration. This Agreement represents the agreement of the
Borrower, the Administrative Agent and the Lenders with respect to the subject
matter hereof, and there are no promises, undertakings, representations or
warranties by the Administrative Agent, or any Lender relative to the subject
matter hereof not expressly set forth herein or in the other Loan Documents.

        10.11 Confidentiality Undertaking. Each of the Lenders, and the
Administrative Agent agree that the financial and other information with respect
to the Borrower and the Pipeline obtained by it pursuant to subsection 5.1, 5.2
or 5.13 that is not available to the general public shall be held confidential
and shall not be disclosed to third parties (other than to the Administrative
Agent or other Lenders); provided, however, that nothing herein shall prevent
the Lenders and the Administrative Agent from disclosing any such information
(a) upon the order, demand or request of, or in connection with any
investigation or audit by, any Governmental

                                       70
<PAGE>

Authority, (b) to any prospective Transferee or to any Person in connection with
the syndication of the commitments and Loans, provided such prospective
Transferee or Person shall have agreed in writing to be bound by the provisions
of this subsection or shall have entered into another confidentiality
undertaking with the Borrower, (c) to such Lender's or the Administrative
Agent's attorneys, professional advisors, independent auditors or Affiliates or
(d) in connection with the exercise of any right or remedy under Section 7 of
this Agreement, any other Loan Document or applicable law.

        10.12 GOVERNING LAW. THIS AGREEMENT AND THE NOTES AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF
NEW YORK.

      venue of any such action or proceeding in any such court or that such
      action or proceeding was brought in an inconvenient court and agrees not
      to plead or claim the same:

        (c)  agrees that service of process in any such action or proceeding may
      be effected by mailing a copy thereof by registered or certified mail (or
      any substantially similar form of mail), postage prepaid, to the Borrower
      at its address set forth in subsection 10.2 or at such other address of
      which the Administrative Agent shall have been notified pursuant thereto;
      and

        (d)  agrees that nothing herein shall affect the right to effect service
      of process in any other manner permitted by law or shall limit the right
      to sue in any other jurisdiction.

        10.14 Acknowledgements. The Borrower hereby acknowledges that:

        (a)   it has been advised by counsel in the negotiation, execution and
      delivery of this Agreement and the Notes;

        (b)  neither the Administrative Agent nor any Lender has any fiduciary

      is solely that of creditor and debtor; and

                                                                      ----------
                          Subordinated Debt Provisions
                          ----------------------------

The unsecured affiliate indebtedness evidenced by this instrument (herein called
the "Affiliate Subordinated Debt") is subordinated and subject in right of
payment to the prior payment in full of all Senior Debt Obligations (as
hereinafter defined) of Iroquois Gas Transmission System, L.P., a limited
partnership formed under the laws of the State of Delaware (the "Borrower").
Each holder of this instrument, by its acceptance hereof, agrees to and shall be
bound by all the provisions hereof.

All capitalized terms used herein and not otherwise defined herein shall have
the meanings attributed to them in the Credit Agreement, dated as of May 30,
2000 (as such agreement may be amended, supplemented or otherwise modified from
time to time, the "Credit Agreement"), among the Borrower, the lenders and other
financial institutions party thereto, The Chase Manhattan Bank, as
Administrative Agent, Bank of Montreal, as Syndication Agent and Fleet National
Bank, as Documentation Agent.

The term "Senior Debt Obligations", as used herein, shall include all loans,
advances, debts, liabilities and obligations, howsoever arising (whether or not
evidenced by any note or instrument and whether or not for the payment of
money), direct or indirect, absolute or contingent, due or to become due, now
existing or hereafter arising (collectively, "Obligations") of the Borrower now
or hereafter existing in respect of Senior Debt and any amendments,
modifications, deferrals, renewals or extensions of any such Senior Debt, or of
any notes or evidences of indebtedness heretofore or hereafter issued in
evidence of or in exchange for any such Obligation, whether for principal,
interest (including interest payable in respect of any such Obligations
subsequent to the commencement of any proceeding against or with respect to the
Borrower under any chapter of the Bankruptcy Code, 11 U.S.C. ss. 101 et seq.
(the "Bankruptcy Code"), or any provision of corresponding bankruptcy,
insolvency or commercial reorganization legislation of any other jurisdiction,
whether or not such interest is an allowed claim enforceable against the debtor,
and whether or not the holder of such obligation would be otherwise entitled to
receive dividends or payments with respect to any such interest or any such
proceeding), fees, expenses or otherwise.

The term "Affiliate Subordinated Debt", as used herein, shall mean all
Obligations of the Borrower owing to any Partner or an Affiliate of any Partner
of the Borrower now or hereafter existing hereunder (whether created directly or
acquired by assignment or otherwise), whether for principal, interest
(including, without limitation, interest accruing after the filing of a petition
initiating any bankruptcy proceeding described in the definition of Senior Debt
Obligations, whether or not such interest accrues after the filing of such
petition for purposes of the Bankruptcy Code or is an allowed claim in such
proceeding), fees, expenses or otherwise.

On and after the Closing Date, no payment on account of principal, interest,
fees, expenses or otherwise on this Affiliate Subordinated Debt shall be made by
the Borrower in cash unless (a) full payment of all amounts then due and payable
on all Senior Debt Obligations has been made, (b) such payment would be
permitted by the Credit

<PAGE>

Agreement, (c) each of the conditions set forth in Section 6.3 of the Credit
Agreement has been satisfied and (d) immediately after giving effect to such
payment, there shall not exist any Default or Event of Default. Any such payment
permitted pursuant to this paragraph is hereinafter referred to as a "Permitted
Payment". For the purposes of these provisions, no Senior Debt Obligations shall
be deemed to have been paid in full until the obligee of such Senior Debt
Obligations shall have indefeasibly received payment in full in cash.

Upon any payment or distribution of assets of the Borrower of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution or winding up or total or partial liquidation or reorganization of
the Borrower, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, then and in any such event all principal,
premium and interest and all other amounts due or to become due upon all Senior
Debt Obligations shall first be paid in full before the holders of the Affiliate
Subordinated Debt shall be entitled to retain any assets so paid or distributed
in respect of the Affiliate Subordinated Debt (or principal, premium, interest
or otherwise) and upon any such dissolution or winding up or liquidation or
reorganization, any payment or distribution of assets of the Borrower of any
kind or character, whether in cash, property or securities, to which the holders
of the Affiliate Subordinated Debt would be entitled, except as otherwise
provided herein, shall be paid pro rata among the holders of Senior Debt
Obligations by the Borrower or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
or by the holders of the Affiliate Subordinated Debt if received by them. So
long as any Senior Debt Obligations are outstanding, the holder of this
instrument shall not commence, or join with any creditor other than the holders
of the Senior Debt Obligations in commencing, or directly or indirectly causing
the Borrower to commence, or assist the Borrower in commencing, any proceeding
referred to in the preceding sentence.

The holder of this instrument hereby irrevocably authorizes and empowers
(without imposing any obligation on) each Senior Party and such Senior Party's
representatives, under the circumstances set forth in the immediately preceding
paragraph, to demand, sue for, collect and receive every such payment or
distribution described therein and give acquittance therefor, to file claims and
proofs of claims in any statutory or nonstatutory proceeding, to vote such
Senior Party's ratable share of the full amount of the Affiliate Subordinated
Debt evidenced by this instrument in its sole discretion in connection with any
resolution, arrangement, plan of reorganization, compromise, settlement or
extension and to take all such other action (including, without limitation, the
right to participate in any composition of creditors and the right to vote such
Senior Party's ratable share of the full amount of the Affiliate Subordinated
Debt at creditors' meetings for the election of trustees, acceptances of plans
and otherwise), in the name of the holder of the Affiliate Subordinated Debt
evidenced by this instrument or otherwise, as such Senior Party's
representatives may deem necessary or desirable for the enforcement of the
subordination provisions of this instrument. The holder of this instrument shall
execute and deliver to each Senior Party and such holder's representatives all
such further instruments confirming the foregoing authorization, and all such
powers of attorney, proofs of claim, assignments of claim and other instruments,
and shall take all such other action as may be

<PAGE>

reasonably requested by such holder or such holder's representatives in order to
enable such holder to enforce all claims upon or in respect of such holder's
ratable share of the Affiliate Subordinated Debt evidenced by this instrument.

The holder of this instrument shall not, without the prior written consent of
the Senior Parties, have any right to accelerate payment of, or institute any
proceeding to enforce, the Affiliate Subordinated Debt so long as any Senior
Debt Obligations are outstanding, unless and until the holders of all Senior
Debt Obligations have accelerated payment thereof and commenced proceedings to
enforce such Senior Debt Obligations.

After the payment in full of all amounts due in respect of Senior Debt
Obligations, the holder or holders of the Affiliate Subordinated Debt shall be
subrogated to the rights of the Senior Parties to receive payments or
distributions of cash, property or securities of the Borrower applicable to
Senior Debt Obligations until the principal of, premium on, interest on and all
other amounts due or to become due with respect to the Affiliate Subordinated
Debt shall be paid in full subject to the terms and conditions of the Affiliate
Subordinated Debt or of any agreement among the holders of the Affiliate
Subordinated Debt and other Affiliate Subordinated Debt of the Borrower.

If any payment (other than a Distribution permitted pursuant to Section 6.3 of
the Credit Agreement) or distribution of assets of the Borrower of any kind or
character, whether in cash, property or securities, shall be received by the
holder of the Affiliate Subordinated Debt in such capacity before all Senior
Debt Obligations are paid in full, such payment or distribution will be held in
trust for the benefit of, and shall be immediately paid over pro rata among the
holders of Senior Debt Obligations, for application to the payment in full of
Senior Debt Obligations, until all Senior Debt Obligations shall have been paid
in full.

Nothing contained in this instrument is intended to or shall impair as between
the Borrower, its creditors (other than the Senior Parties) and the holders of
the Affiliate Subordinated Debt, the Obligations of the Borrower to pay to the
holders of the Affiliate Subordinated Debt, as and when the same shall become
due and payable in accordance with their terms, or to affect the relative rights
of the holders of the Affiliate Subordinated Debt and creditors of the Borrower
(other than the Senior Parties).

The holders of the Senior Debt Obligations shall not be prejudiced in their
rights to enforce the subordination contained herein in accordance with the
terms hereof by any act or failure to act on the part of the Borrower.

The holder of this instrument agrees to execute and deliver such further
documents and to do such other acts and things as the Senior Parties may
reasonably request in order fully to effect the purposes of these subordination
provisions. Each holder of this instrument by its acceptance hereof authorizes
and directs The Chase Manhattan Bank, in its capacity as the Trustee under the
Senior Indenture, on its behalf to take such further action as may be necessary
to effectuate the subordination as provided herein and appoints the Trustee as
its attorney-in-fact for any and all such purposes.

<PAGE>

The subordination effected by these provisions, and the rights of the Senior
Parties, shall not be affected by (i) any amendment of, or addition or
supplement to, the Credit Agreement, any other Senior Debt Agreement, or any
other document evidencing Senior Debt Obligations, (ii) any exercise or
nonexercise of any right, power or remedy under or in respect to the Credit
Agreement, any other Senior Debt Agreement, or any other document evidencing or
securing Senior Debt Obligations or (iii) any waiver, consent, release,
indulgence, extension, renewal, modification, delay, or other action, inaction
or omission, in respect of the Credit Agreement, any other Senior Debt
Agreement, or any other document evidencing Senior Debt Obligations; whether or
not any holder of any Affiliate Subordinated Debt shall have had notice or
knowledge of any of the foregoing.

No failure on the part of any Senior Party to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor all any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

The holder of this instrument and the Borrower each hereby waive promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Senior Debt Obligations and these terms of subordination and any requirement
that any Senior Party protect, secure, perfect or insure any Lien or any
property subject thereto or exhaust any right to take any action against the
Borrower or any other Person.

These terms of subordination shall continue to be effective or be reinstated, as
the case may be, if at any time any payment of any of the Senior Debt
Obligations is rescinded or must otherwise be returned by any Senior Party upon
the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all
as though such payment had not been made.

The provisions of these terms of subordination constitute a continuing agreement
and shall (i) remain in full force and effect until the payment in full of the
Senior Debt Obligations, (ii) be binding upon the holder of this instrument, the
Borrower and its successors, transferees and assignees and (iii) inure to the
benefit of, and be enforceable by, each Senior Party. Without limiting the
generality of the foregoing clause (iii), the Senior Party may assign or
otherwise transfer all or any portion of its rights and obligations under all or
any of the Senior Debt Agreements to any other Person (to the extent permitted
by the Senior Debt Agreements), and such other Person shall thereupon become
vested with all the rights in respect thereof granted to such Senior Party
herein or otherwise.

This instrument shall be governed by and construed in accordance with, the laws
of the State of New York, without giving effect to the conflict of law
principles thereof.

                  FOR VALUE RECEIVED, the undersigned Iroquois Gas Transmission
System, L.P., a Delaware limited partnership (the "Borrower"), hereby
unconditionally promises to pay to the order of [LENDER] (the "Lender") at the
office of The Chase Manhattan Bank (together with its successors in such
capacity, the "Administrative Agent"), located at 270 Park Avenue, New York, New
York 10017, in lawful money of the United States of America and in immediately
available funds, in accordance with Section 2.16 of the Credit Agreement (as
hereinafter defined), of ___________________ Dollars ($[ ]) or, if less, the
aggregate unpaid principal amount of all Term Loans made by the Lender to the
Borrower pursuant to Section 2.1 of that certain Credit Agreement dated as of
May 30, 2000, among the Borrower, the Lenders parties thereto, the
Administrative Agent, Bank of Montreal, as Syndication Agent and Fleet National
Bank, as Documentation Agent (as amended, restated, supplemented or otherwise
modified from time to time, the "Credit Agreement"). All capitalized terms used
herein and not defined herein shall have the meanings given to them in the
Credit Agreement.

                  The Borrower further agrees to pay interest in like money at
such office on the unpaid principal amount hereof from time to time outstanding
at the rates and on the dates specified in Section 2.13 of the Credit Agreement.

                  The holder of this promissory note is authorized to endorse on
the schedules annexed hereto and made a part hereof or on a continuation thereof
that shall be attached hereto and made hereof, the date, Type and amount of each
Term Loan made pursuant to the Credit Agreement and the date and amount of each
payment or prepayment of principal thereof, each continuation thereof, each
conversion of all or a portion thereof to another Type and, in the case of
Eurodollar Term Loans, the length of each Interest Period with respect thereto.
Each such endorsement shall constitute prima facie evidence of the accuracy of
the information endorsed, provided that the failure to make any such endorsement
or any error of such endorsement shall not affect the obligations of the
Borrower in respect of any Term Loan.

                  This promissory note is one of the Notes referred to in, and
is entitled to the benefits of, the Credit Agreement which, among other things,
contain provisions for

<PAGE>

the Lender making the Loans, the indebtedness of the Borrower resulting
therefrom being evidenced by this promissory note, the acceleration of the
maturity of principal upon occurrence of Events of Default and is subject to the
provisions of the Credit Agreement for prepayments in whole or in part on
accounts of the principal balance hereof prior to the maturity hereof.

                  Upon the occurrence of any one or more of the Events of
Default specified in the Credit Agreement, all amounts then remaining unpaid on
this promissory note shall become, or may be declared to be, immediately due and
payable, all as provided in the Credit Agreement.

                  Except as expressly provided in Section 7 of the Credit
Agreement, Borrower hereby waives presentment, demand, notice of dishonor,
protest and any other notice or formality with respect to this promissory note.

                  In no contingency or event whatsoever shall interest be
charged hereunder, however such interest may be characterized or computed if it
would exceed the highest interest permissible under any law which a court of
competent jurisdiction shall, in a final determination, deem applicable hereto.
In event that such a court determine that the Lender has received interest
hereunder in excess of the highest rate applicable hereto, any such excess
interest collected by the Lender shall be deemed to have been a repayment of
principal and shall be so applied.

                  None of the Partners or the Partner Parents shall be
personally liable for any obligation of the Borrower under this promissory note
or for the performance of any obligation of the Borrower hereunder. The
exclusive recourse of the Lender for the satisfaction of payment under this
promissory note shall be against the Borrower and its assets (and not against
any assets or property of the Partners or the Partner Parents). In the event
that any default occurs in connection with the obligations of the Borrower under
this promissory note, no action shall be brought against the Partners or the
Partner Parents if such action is predicated solely on such Person's direct or
indirect ownership in the Borrower. In the event of foreclosure or other sale or

                                                              [__________], 2000

                  FOR VALUE RECEIVED, the undersigned IROQUOIS GAS TRANSMISSION
SYSTEM, L.P., a Delaware limited partnership (the "Borrower"), hereby
unconditionally promises to pay to the order of [LENDER] (the "Lender") at the
office of The Chase Manhattan Bank (together with its successors in such
capacity, the "Administrative Agent"), located at 270 Park Avenue, New York, New
York 10017, in lawful money of the United States of America and in immediately
available funds, in accordance with Section 2.16 of the Credit Agreement (as
hereinafter defined), of ___________________ Dollars ($[ ]) or, if less, the
aggregate unpaid principal amount of all Revolving Credit Loans made by the
Lender to the Borrower pursuant to Section 2.2 of that certain Credit Agreement
dated as of May 30, 2000, among the Borrower, the Lenders, the Administrative
Agent, Bank of Montreal, as Syndication Agent and Fleet National Bank, as
Documentation Agent (as amended, restated, supplemented or otherwise modified
from time to time, the "Credit Agreement"). All capitalized terms used herein
and not defined herein shall have the meanings given to them in the Credit
Agreement.

                  The Borrower further agrees to pay interest in like money at
such office on the unpaid principal amount hereof from time to time outstanding
at the rates and on the dates specified in Section 2.13 of the Credit Agreement.

                  The holder of this promissory note is authorized to endorse on
the schedules annexed hereto and made a part hereof or on a continuation thereof
that shall be attached hereto and made hereof, the date, Type and amount of each
Revolving Credit Loan made pursuant to the Credit Agreement and the date and
amount of each payment or prepayment of principal thereof, each continuation
thereof, each conversion of all or a portion thereof to another Type and, in the
case of Eurodollar Revolving Credit Loans, the length of each Interest Period
with respect thereto. Each such endorsement shall constitute prima facie
evidence of the accuracy of the information endorsed, provided that the failure
to make any such endorsement or any error of such endorsement shall not affect
the obligations of the Borrower in respect of any Revolving Credit Loan.

                  This promissory note is one of the Notes referred to in, and
is entitled to the benefits of, the Credit Agreement which, among other things,
contain provisions for the Lender making the Loans, the indebtedness of the
Borrower resulting therefrom being evidenced by this promissory note, the
acceleration of the maturity of principal upon occurrence of Events of

<PAGE>

Default and is subject to the provisions of the Credit Agreement for prepayments
in whole or in part on accounts of the principal balance hereof prior to the
maturity hereof.

                  Upon the occurrence of any one or more of the Events of
Default specified in the Credit Agreement, all amounts then remaining unpaid on
this promissory note shall become, or may be declared to be, immediately due and
payable, all as provided in the Credit Agreement.

                  Except as expressly provided in Section 7 of the Credit
Agreement, Borrower hereby waives presentment, demand, notice of dishonor,
protest and any other notice or formality with respect to this promissory note.

                  In no contingency or event whatsoever shall interest be
charged hereunder, however such interest may be characterized or computed if it
would exceed the highest interest permissible under any law which a court of
competent jurisdiction shall, in a final determination, deem applicable hereto.
In event that such a court determine that the Lender has received interest
hereunder in excess of the highest rate applicable hereto, any such excess
interest collected by the Lender shall be deemed to have been a repayment of
principal and shall be so applied.

                  None of the Partners or the Partner Parents shall be
personally liable for any obligation of the Borrower under this promissory note
or for the performance of any obligation of the Borrower hereunder. The
exclusive recourse of the Lender for the satisfaction of payment under this
promissory note shall be against the Borrower and its assets (and not against
any assets or property of the Partners or the Partner Parents). In the event
that any default occurs in connection with the obligations of the Borrower under
this promissory note, no action shall be brought against the Partners or the
Partner Parents if such action is predicated solely on such Person's direct or
indirect ownership in the Borrower. In the event of foreclosure or other sale or
disposition of properties, no judgment for any deficiency upon the obligations
of the Borrower under this promissory note shall be obtainable by the Lender
against the Partners or the Partner Parents.

                  THIS PROMISSORY NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

             Form of Shearman & Sterling's Opinion for the Borrower

         Shearman & Sterling shall have furnished to the Administrative Agent
their written opinion, as counsel to the Borrower, addressed to the
Administrative Agent and the Lenders and dated the Closing Date, in form and
substance reasonably satisfactory to the Administrative Agent, substantially to
the effect set forth below:

         1. Assuming that the Credit Agreement has been duly authorized,
executed and delivered by the Borrower, the Credit Agreement constitutes a valid
and legally binding agreement of the Borrower enforceable against the Borrower
in accordance with its terms, except to the extent that such enforceability may
be limited by applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws affecting creditors' rights
generally and by general equitable principles (whether considered in a
proceeding in equity or at law);

         2. The execution, delivery and performance by the Borrower of each of
the Purchase Agreement dated May 22, 2000 for the sale of $200,000,000 8.68%
Senior Notes due 2010 among the Borrower, Chase Securities, Inc. and Credit
Suisse First Boston Corporation (the "Purchase Agreement"), the Senior
Indenture, the Exchange and Registration Rights Agreement dated as of May 30,
2000 substantially in the form attached as Annex A to the Purchase Agreement
(the "Registration Rights Agreement"), the Securities and the Credit Agreement
(collectively, the "Senior Debt Documents"), the borrowings under the Credit
Agreement and compliance by the Borrower with the terms thereof and the
consummation of the transactions contemplated by the Senior Debt Documents will
not conflict with or result in a breach or violation of any of the terms or
provisions of, or constitute a default in any material respect under, or result
in the creation or imposition of any lien, charge or encumbrance upon any
property or assets of the Borrower or Iroquois Pipeline Operating Company (the
"Operator") pursuant to any material contract listed on Schedule A hereto, nor
will such actions result in any violation of the provisions of the constituent
documents of the Borrower or the Operator or any statute or any judgment, order,
decree, rule or regulation known to such counsel of any court or arbitrator or
governmental agency or body having jurisdiction over the Borrower or the
Operator or any of their properties or assets; and no consent, approval,
authorization or order of, or filing or registration with, any such court or
arbitrator or governmental agency or body under any such statute, judgment,
order, decree, rule or regulation is required for the execution, delivery and
performance by the Borrower of each of the Senior Debt Documents, the borrowings
under the Credit Agreement and compliance by the Borrower with the terms thereof
and the consummation of the transactions contemplated by the Senior Debt
Documents, except for such consents, approvals, authorizations, filings,
registrations or qualifications (i) which have been obtained or made prior to
the Closing Date and (ii) as may be required to be obtained or made under the
Securities Act and applicable state securities laws as provided in the
Registration Rights Agreement;

         3. Except as disclosed in the Offering Memorandum, to the knowledge of
such counsel, there are no pending actions or suits or judicial, arbitral,
rule-making,

<PAGE>

administrative or other proceedings to which the Borrower or the Operator is a
party or of which any property or assets of the Borrower or the Operator is the
subject which (A) singularly or in the aggregate, if determined adversely to the
Borrower or the Operator, would reasonably be expected to have a Material
Adverse Effect or (B) questions the validity or enforceability of any of the
Senior Debt Documents or any action taken or to be taken pursuant thereto; and
to the best of the knowledge of such counsel, no such proceedings are threatened
or contemplated by governmental authorities or threatened by others; and

         4. Neither the Borrower nor the Operator is (A) an "investment company"
or a company "controlled by" an investment company within the meaning of the
Investment Company Act of 1940, as amended, and the rules and regulations of the
Commission thereunder, without taking account of any exemption under the
Investment Company Act arising out of the number of holders of the Borrower's
securities or (B) a "holding company " or a "subsidiary company" of a holding
company or an "affiliate" thereof within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

         In rendering such opinions, such counsel may rely as to matters of
fact, to the extent such counsel deems proper, on certificates of responsible
officers of the Borrower and public officials which are furnished to the
Administrative Agent.

                    act pending the receipt of such instructions, and shall have
                    no liability for any act in good faith in compliance
                    therewith, or for its good faith failure to act pending
                    receipt thereof.

               3.5  Operator's Subcontract. Operator and Tennessee Gas Pipeline
                    Company ("Tennessee") have executed an Agreement with
                    Respect to Iroquois Gas Transmission System, L.P.
                    ("Tennessee Subcontract"), pursuant to

                                       11
<PAGE>

                    which Tennessee has assumed responsibility for performing
                    certain of the duties and obligations delegated by
                    Partnership to Operator under this Agreement. Any
                    replacement or substitute subcontract with Tennessee or any
                    other entity shall, prior to its execution and as a
                    condition thereto, be approved by the Management Committee.
                    All costs, liabilities and expenses incurred by Operator
                    under the Tennessee Subcontract, and all costs, liabilities
                    and expenses incurred by Operator under any replacement or
                    substitute subcontract approved by the Management Committee
                    ("Approved Substitute Subcontract"), shall be reimbursable
                    costs pursuant to Section 5 of this Agreement.

                    Partnership further agrees that Operator shall not be liable
                    in any manner for any default under this Agreement which
                    results in whole or in part, directly or indirectly from a
                    default by Tennessee under the Tennessee Subcontract, or by
                    any substitute subcontractor under an Approved Substitute
                    Subcontract. In the event of a default by Operator under
                    this Agreement which results in whole or in part, directly
                    or indirectly from a default by Tennessee under the
                    Tennessee Subcontract, or by any substitute subcontractor
                    under an Approved Substitute Subcontract, Operator hereby
                    assigns to Partnership any rights which Operator may have
                    under the Tennessee Subcontract or the Approved Substitute

                                       12
<PAGE>

                    Subcontract (as the case may be) to seek and receive damages
                    from Tennessee or the substitute subcontractor (as the case
                    may be) in connection with such default.

                    Partnership further acknowledges and consents to the
                    assignment by Operator to Tennessee in the Tennessee
                    Subcontract and/or to a substitute subcontractor in an
                    Approved Substitute Subcontract of certain of Operator's
                    rights to receive payments from Partnership under this
                    Agreement in the event of a default by Operator under the
                    Tennessee Subcontract or Approved Substitute Subcontract
                    which results in whole or in part, directly or indirectly
                    from a default by Partnership under this Agreement.

4.             Employees, Consultants and Contractors.

               4.1  Operator's Employees, Consultants and Contractors. Operator
                    shall employ or retain and have supervision over the Persons
                    (including consultants and professional service or other
                    organizations) required by Operator to perform its duties
                    and responsibilities hereunder in an efficient and
                    economically prudent manner. Operator shall pay all
                    reasonable expenses in connection therewith, including
                    compensation, salaries, wages, overhead and administrative
                    expense incurred by Operator and its Affiliates, and, if
                    applicable, social security taxes,

                                       13
<PAGE>

                    workers' compensation insurance, retirement and insurance
                    benefits and other such expenses. The compensation for
                    Operator's employees shall be determined by Operator. All
                    authorized expenses pursuant to this Section shall be
                    reimbursable costs under Section 5 of this Agreement.

               4.2  Affiliates of Operator or Partners. The Operator shall be
                    authorized to utilize, as it deems necessary, the services
                    of its corporate Affiliates, provided that such services are
                    utilized on terms materially no less favorable to the
                    Partnership than those prevailing at the time for comparable
                    services of unaffiliated independent Parties. The Operator
                    shall also be authorized to utilize, as it deems necessary,
                    the services of independent contractors, including the
                    services of any Partner's corporate Affiliates, provided
                    that the services of any such corporate Affiliate are
                    utilized on terms materially no less favorable to the
                    Partnership than those prevailing at the time for comparable
                    services of unaffiliated independent parties, and the
                    Operator shall negotiate contracts for such services and
                    execute the same.

               4.3  Standards for Operator and its Employees. Operator shall
                    perform its services and carry out its responsibilities
                    hereunder and shall require all of its employees and
                    contractors, subcontractors, and materialmen furnishing
                    labor, material or services for the construction and
                    operation of the Facilities to carry out their
                    responsibilities, in accordance with

                                       14
<PAGE>

                    sound, workmanlike and prudent practices of the gas pipeline
                    industry and in compliance with all relevant laws, statutes,
                    ordinances, safety codes, regulations and rules of
                    governmental authorities having jurisdiction applicable to
                    the Facilities.

               4.6  Non-Discrimination. In performing under this Agreement,
                    Operator will not discriminate against any employee or
                    applicant for employment because of race, creed, color,
                    religion, sex, national origin, age or disability, or
                    because he or she is a disabled veteran or a veteran of the
                    Vietnam era, and will comply with all provisions of
                    Executive Order 11246 of September 24, 1965 and any
                    successor order thereto, to the extent that such provisions
                    are applicable to Operator and/or Partnership. The
                    provisions of this Section 4.4 shall be applicable to any
                    contractors, consultants and/or subcontractors retained in
                    connection herewith.

5.             Financial and Accounting.

               5.1  Accounting and Compensation.

                    5.1.1  Operator shall keep a full and complete account of
                           all costs, expenses and expenditures incurred by it
                           on behalf of the Partnership in connection with its
                           obligations hereunder.

                                       15
<PAGE>

                    5.1.2  Operator shall be reimbursed by Partnership for all
                           reasonable and proper costs, expenses and
                           expenditures incurred by it on behalf of the
                           Partnership in accordance with the provisions of this
                           Agreement; provided, however, that costs incurred by
                           the Operator under Section 8.1 of this Agreement
                           shall not be reimbursed by the Partnership. It is the
                           intent of the Parties that Operator shall carry out
                           its services hereunder on a fully reimbursed basis,
                           pursuant to the provisions of this Agreement, without
                           profit or loss. To the extent that Operator incurs
                           such profit or loss appropriate adjustments will
                           promptly be made to eliminate such profit or loss.
                           Since Operator maintains custody of Partnership funds
                           and maintains the books and records of the
                           Partnership, the Operator's reimbursement under this
                           Agreement shall be made by appropriate accounting
                           entries and Operator shall not be required to render
                           bills or statements to the Partnership.

               5.2  Budgets. On or before each November 1, Operator shall
                    prepare and submit for approval of the Management Committee
                    an estimate of capital expenditures and operating income and
                    expenses which Operator anticipates for the ensuing Year
                    broken down into such individual line items and including
                    such supporting documentation and data as the

                                       16
<PAGE>

                    Management Committee may reasonably require. Except as the
                    Management Committee may otherwise direct, the budget
                    approved by the Partnership and then in effect shall
                    constitute authorization of Operator to incur the
                    expenditures contained in such budget and to incur
                    expenditures up to ten percent (10%) in excess of the amount
                    set forth for any line item in such budget, provided that
                    the total of all such expenditures in excess of budgeted
                    line item amounts shall not exceed five percent (5%) of the
                    total amount of such budget. Operator shall immediately
                    inform the Management Committee of any facts which the
                    Operator believes may increase or decrease any line item in
                    the most recent budget approved by the Management Committee
                    by ten percent (10%) or more or increase or decrease the
                    total amount of such budget by five percent (5%) or more.

               5.3  Disputed Charges. Subject to the provisions of Section 3.5,
                    Partnership may, within twenty-four (24) months after the
                    expenditure, take written exception to any expenditure or
                    any part thereof, on the ground that the same was not a
                    reasonable, authorized and proper cost incurred by Operator
                    on behalf of the Partnership in connection with the design,
                    construction, operation, maintenance, or administration of
                    the Facilities. If the amount as to which such written
                    exception is taken or any part thereof is ultimately
                    determined in accordance with Section 13 of this

                                       17
<PAGE>

                    Agreement not to be a reasonable, authorized, and proper
                    expense incurred by Operator on behalf of the Partnership in
                    connection with the design, construction, operation,
                    maintenance, or administration of the Facilities, such
                    amount or portion thereof (as the case may be) shall be
                    refunded by Operator to Partnership together with interest
                    thereon at a rate (which in no event shall be higher than
                    the maximum rate permitted by applicable law) equal to the
                    rate designated by Morgan Guaranty Trust Company from time
                    to time as its prime rate, plus one percent, during the
                    period from the date of payment by Partnership to the date
                    of refund by Operator.

               5.4  Rate Reviews. Operator shall review from time to time the
                    rates and fees charged for transportation services and
                    recommend to Partnership revision in such rates and fees as
                    necessary to reflect increased or decreased costs or other
                    changes in the conditions of service in order to assure that
                    all costs are reflected in the tariffs of Partnership.
                    Operator shall have the authority to prepare, file and
                    prosecute, on behalf of the Partnership and without further
                    approval of the Management Committee, revisions to such
                    rates and fees which will not affect annual revenues by more
                    than $100,000.

               5.5  Audit and Examination. In addition to the audit
                    responsibilities assigned by the Partnership Agreement to
                    the Audit Committee, any Partner(s),

                                       18
<PAGE>

                    the Partnership or their designated representatives
                    (including in the case of the Partnership representatives
                    from each Partner), after fifteen (15) Days' notice in
                    writing to Operator, shall have the right during normal
                    business hours to audit or examine, at the expense of the
                    Person (Partner(s) or Partnership) conducting the audit or
                    examination, all books and records maintained by the
                    Operator as well as the relevant books of account of
                    Operator's contractors relating to the design, construction,
                    operation, maintenance, and administration of the
                    Facilities, provided, however, that the total number of full
                    audits commenced in any Year shall not exceed two. Such
                    right shall include the right to meet with Operator's
                    internal and independent auditors to discuss matters
                    relevant to the audit or examination. Partnership shall have
                    two (2) Years after the close of a Year in which to make an
                    audit of Operator's records for such Year; provided,
                    however, that any audits relating to construction costs may
                    be made up to twenty-four (24) Months after the Completion
                    Date. Absent fraud or intentional concealment or
                    misrepresentation by Operator or its employees, and except
                    for any adjustments which may arise from FERC compliance
                    audits, Operator shall neither be required nor permitted to
                    adjust any item unless a claim therefor is presented or
                    adjustment is initiated within two (2) Years after the close
                    of the Year in which the cost was incurred,

                                       19

<PAGE>

                    and in the absence of such timely claims or adjustments, the
                    costs incurred shall be conclusively established as correct;
                    provided, however, this shall not prevent adjustment
                    resulting from physical inventory of the Facilities and
                    other property or audit adjustments relating to construction
                    costs incurred during the construction phase as set forth in
                    this Section 5.5.

6.             Agent.

               6.1  Agent. In performing services pursuant to this Agreement,
                    Operator shall be an agent of Partnership.

7.             Intellectual Property.

               7.1  Inventions and Copyrights. Any (i) inventions, whether
                    patentable or not, developed or invented, or (ii)
                    copyrightable material, developed by Operator or its
                    employees while engaged exclusively in the performance of
                    services under this Agreement shall, unless otherwise
                    directed, be assigned to Partnership, which shall have the
                    exclusive right to the exploitation thereof.

               7.2  Confidentiality. Operator and Partnership shall comply with
                    the provisions applicable to confidential information set
                    out in Section 13.12

                    of the Partnership Agreement, which provisions are
                    incorporated herein by reference as if set out in full.

               7.3  License to Operator. Each Partner which is a signatory to
                    this Operating Agreement hereby grants to the Operator on
                    behalf of the Partnership an irrevocable, royalty-free,
                    non-exclusive and a non-assignable license to use, during
                    the term of this Operating Agreement, any confidential
                    information provided to the Partnership or Operator by said
                    Partner and designated as such by the Partner, or generated
                    by the Partnership or Operator on behalf of said Partner or
                    Partnership during the term of the aforesaid Partnership
                    Agreement. For purposes of this Section 7.3, confidential
                    information shall include, but shall not be limited to,
                    inventions (whether patented or not) and copyrighted or
                    copyrightable material. As a condition precedent to the
                    effectiveness of the aforesaid license to use, Operator
                    hereby expressly agrees that it will utilize such

                           Agreement; otherwise, such decision shall be made by
                           the Management Committee, and any settlement or
                           defense thereof by the Partnership shall be
                           controlled by the Management Committee.

               8.3  Insurance.

                    8.3.1  Operator shall carry and maintain insurance which it
                           reasonably deems adequate to protect Operator, its
                           officers, agents and employees against all actions,
                           claims, demands, costs and liabilities arising out of
                           the negligence of Operator, its officers, agents and
                           employees in connection with their good faith acts
                           (or failure to act) within the scope of Operator's
                           authority under this Operating Agreement. Operator
                           shall, subject to the approval of the Management
                           Committee, carry and maintain such other insurance
                           for the benefit of the Partnership and Operator and
                           require contractors, subcontractors or consultants to
                           carry and maintain insurance deemed adequate by the
                           Operator, as approved by the Management Committee,
                           (i) to

                                       24
<PAGE>

                           protect the Partnership and Operator and (ii) satisfy
                           any other requirement of the law.

                    8.3.2  Insurance maintained by the Operator pursuant to
                           Section 8.3.1 of this Agreement shall be a
                           reimbursable cost pursuant to Section 5 of this
                           Agreement.

                    8.3.3  Operator may carry and maintain such other insurance
                           for its own account as it may deem necessary, but in
                           the event other insurance is carried, unless
                           otherwise directed by the Partnership, Operator
                           agrees to waive, and agrees to undertake in good
                           faith to have its insurers waive, any rights of
                           subrogation they may have against the Partnership and
                           the individual Partners thereof, or the Affiliates of
                           any of them, and/or their directors, officers,
                           employees, servants or agents.

                    8.3.4  With respect to claims and losses for damage, injury
                           or destruction of property which is a part of the
                           Facilities, which property is covered by insurance
                           other than insurance provided for in Section 8.3.1 of
                           this Agreement, it is agreed that neither Operator
                           nor the Partnership or any of its Partners shall have
                           any rights of recovery against one another, nor
                           against the Affiliates of each, nor the insurers of
                           any of them, and their rights of

                                       25
<PAGE>

                           recovery are mutually waived. All such policies of
                           insurance purchased to cover the Facilities or any
                           part thereof, or the operation (in any respect) of
                           the Facilities or any part thereof, or any gas
                           transported or handled therein, shall be endorsed
                           properly to effectuate this waiver of recovery,
                           provided, however, that if Partnership, any of the
                           Partners, or Operator is unable, despite its best
                           efforts, to obtain such an endorsement, then the
                           other parties may waive or appropriately modify this
                           requirement.

               8.4  Limitation of Liability. Partnership and Operator hereby
                    agree that any claim against Partnership which may arise
                    hereunder shall be made only against the assets of the
                    Partnership and that all rights to proceed against the
                    Partners and the assets of the Partners, other than their
                    interests in the Partnership, as a result of any such claim
                    or any obligation arising therefrom, are hereby expressly
                    waived.

9.             Term.

               9.1  Term. The Original Operating Agreement shall terminate and
                    this Agreement shall be effective as of February 28, 1997
                    and, subject to the provisions of the Partnership Agreement,
                    shall continue until November 30, 2011, and thereafter on a
                    year-to-year basis subject to

                                       26
<PAGE>

                    termination by either Party upon one year's written notice
                    to the other Party, unless sooner terminated pursuant to
                    Section 10 of this Agreement.

10.            Termination.

               10.1 Removal of Operator.

                    10.1.1 The Operator may be removed as Operator as provided
                           in Section 9.8 of the Partnership Agreement. If the
                           Management Committee votes to remove the Operator in
                           accordance with such procedures, then this Agreement
                           shall terminate upon one year's notice to the
                           Operator after such vote and Partnership shall
                           reimburse Operator for any unreimbursed costs
                           incurred by Operator pursuant to Section 5.1 of this
                           Agreement.

                    10.1.2 In the event of a material default by Operator in the
                           performance of its obligations under this Agreement
                           which shall have continued for a period of sixty (60)
                           Days after written notice thereof by Partnership to
                           Operator, Partnership may terminate this Agreement by
                           written notice to Operator, provided, however, that
                           no termination shall occur if: (i) Operator has
                           initiated action to cure such material default but,
                           despite its best efforts, has been unable to complete
                           cure

                                       27
<PAGE>

                           within such sixty (60) Day period and Operator's
                           actions to complete cure are continuing in good faith
                           beyond the end of the sixty (60) Day period, or (ii)
                           such default results in whole or in part, directly or
                           indirectly, from a default by Tennessee under the
                           Tennessee Subcontract or by a substitute
                           subcontractor under an Approved Substitute
                           Subcontract.

               10.2 Continuing Default by Partnership. In the event of a
                    material default by Partnership in the performance of its
                    obligations under this Agreement and the continuance of such
                    material default for a period of sixty (60) Days after
                    written notice thereof by Operator to Partnership, Operator
                    may, by written notice to Partnership, terminate this
                    Agreement, provided, however, that no termination shall
                    occur if Partnership has initiated action to cure such
                    material default but, despite its best efforts, has been
                    unable to complete such cure within such sixty (60) Day
                    period, and Partnership's actions to complete cure are
                    continuing in good faith beyond the end of the sixty (60)
                    Day period.

               10.3 Additional Events of Termination. In addition to termination
                    in accordance with Sections 10.1 and 10.2, this Agreement
                    shall terminate when:

                           becomes a Withdrawn Partner under the Partnership
                           Agreement, unless the remaining Partners vote, by 65%
                           or more of their Percentage Interests, to retain
                           Operator as Operator within thirty (30) Days of the
                           date that Operator Affiliate becomes a Withdrawn
                           Partner and Operator agrees to continue as Operator.

                    10.3.2 Operator Affiliate transfers all or substantially all
                           of its interest in the Partnership, unless such a
                           transfer is a transfer to an Affiliate of Operator
                           Affiliate permitted under Sections 11.3 and 11.4 of
                           the Partnership Agreement.

                    10.3.3 The Partnership is dissolved in accordance with
                           Sections 12.2 or 12.5 of the Partnership Agreement.

                           Partnership, terminates this Agreement.

                           on appeal or otherwise and in effect for 90 days, in
                           an involuntary case under the federal bankruptcy
                           laws, or any such order adjudicating the

                           applicable bankruptcy, insolvency or liquidation law,
                           or the commencement by the Operator of a voluntary
                           case under any bankruptcy or insolvency law.

               10.4 Operator's Costs, Expenses and Actions Upon Termination. In
                    addition to any costs for which Partnership may be obliged
                    to reimburse Operator pursuant to Section 5 of this
                    Agreement, upon any termination of this Agreement
                    Partnership shall pay to Operator any and all costs and
                    expenses reasonably incurred by Operator in connection with
                    the winding up of Operator's duties as Operator and the
                    transfer of such responsibilities and any assets of
                    Partnership held hereunder to Partnership or any other
                    entity as may be directed by Partnership. In the event of
                    any such termination, Operator shall, if so directed by
                    Partnership, transfer to Partnership, or to another entity,
                    any and all assets of Partnership held by Operator
                    hereunder, including but not limited to all permits,
                    licenses, contract rights and other real and personal
                    property, whether tangible or intangible.

11.            Survival of Obligations. The termination of this Agreement shall
               not discharge either Party from any obligation which it owes to
               the other Party by reason of any transaction, commitment or
               agreement entered into, or any loss, cost, damage, expense or
               liability which shall occur or arise (or the circumstances,

                                       30
<PAGE>

               events or basis of which shall occur or arise) prior to such
               termination. It is the intent of the Parties that any obligation
               owed by a Party to the other Party (whether the same shall be
               known or unknown at the termination hereof, or whether the
               circumstances, events or basis of the same shall be known or
               unknown at the termination hereof) shall survive the termination
               of this Agreement.

12.            Accounting and Taxes.

               12.1 Consistent with Partnership Agreement. The accounting and
                    tax service provided by Operator shall be consistent with
                    the applicable provisions of Section 8 of the Partnership
                    Agreement which are incorporated by reference herein as if
                    set forth in full. Matters of tax policy for the Partnership
                    shall be the responsibility of, and ultimately determined by
                    the Management Committee in accordance with Section 8.6 of
                    the Partnership Agreement.

13.            Law of the Contract and Arbitration.

               13.1 Law of the Contract. This Agreement shall be construed and
                    interpreted under the laws of the State of Delaware, without
                    regard to the principles of conflicts of laws.

               13.2 Arbitration.

                    13.2.1 In the event that the Parties are unable to agree on
                           any of the matters set forth herein, either
                           Partnership or Operator may upon written notice prior
                           to the commencement of legal proceedings related to
                           such dispute call for submission of such matter to
                           arbitration. The Party requesting arbitration shall
                           set forth in such notice in adequate detail the
                           issues to be arbitrated, and within ten (10) Days
                           from the receipt of such notice, the other Party may
                           set forth in adequate detail additional related
                           issues to be arbitrated. If arbitration is invoked by
                           either Party, the decision of the arbitrators shall
                           be final and binding upon all parties.

                    13.2.2 It is the intent of the Parties that, to the extent
                           practicable, such binding arbitration shall be
                           conducted by a person knowledgeable and experienced
                           in the type of matter that is the subject of the
                           dispute. In the event the Parties are unable to agree
                           upon such person, then each Party shall select a
                           person that it believes has the qualifications set
                           forth above as its designated arbitrator, and such
                           arbitrators so designated shall mutually agree upon a
                           similarly qualified third person to complete the
                           arbitration panel, provided, however, that if one of

                                       32
<PAGE>

                           the Parties fails to select its designated arbitrator
                           as specified herein within thirty (30) Days of
                           receiving written notice from the other Party that
                           such other Party has selected its designated
                           arbitrator, then the arbitration provided for herein
                           shall be conducted by the one arbitrator so
                           designated. In the event that the persons selected by
                           the Parties are unable to agree on a third member of
                           the panel within sixty (60) Days after their
                           selection, such person shall be designated by the
                           American Arbitration Association. Upon final
                           selection of the entire panel, such panel shall, as
                           expeditiously as possible, render a decision on the
                           matter submitted for arbitration. The arbitration
                           shall be conducted in accordance with the commercial
                           arbitration rules of the American Arbitration
                           Association.

                    13.2.3 Upon the determination of any such dispute, the
                           arbitrators shall bill the costs attributable to such
                           binding arbitration to the Party whose position they
                           determine is farthest away from the actual decision
                           rendered; provided, however, that the arbitrators
                           shall be empowered to apportion such cost between the
                           Parties if they deem it appropriate.

                    13.2.4 It is the intent of the Parties that once arbitration
                           is invoked by either Party pursuant to the provisions
                           of this Section 13 that

                                       33
<PAGE>

                           the matters set for arbitration be decided as set
                           forth herein and they shall not seek to have this
                           Section 13 rendered unenforceable or to have such
                           matter decided in any other way, provided, however,
                           that nothing herein shall prevent the Parties from
                           negotiating a settlement of any issue at any time.

14.            Force Majeure.

               14.1 Effect of Force Majeure. In the event that either
                    Partnership or Operator is rendered unable, by reason of an
                    event of force majeure, as defined herein, to perform,
                    wholly or in part, any obligation or commitment set forth in
                    this contract, then upon such Party's giving notice and full
                    particulars of such event as soon as practicable after the
                    occurrence thereof, the obligations of both Parties, except
                    for unpaid financial obligations arising prior to such event
                    of force majeure, shall be suspended to the extent and for
                    the period of such force majeure condition.

               14.2 Nature of Force Majeure. The term "force majeure" as
                    employed in this Agreement shall mean acts of God, strikes,
                    lockouts or industrial disputes or disturbances, civil
                    disturbances, arrests and restraint from rulers of people,
                    interruptions by government or court orders, present and
                    future valid orders, decisions or rulings of any government
                    or regulatory entity

                                       34

                    having proper jurisdiction, acts of the public enemy, wars,
                    riots, blockades, insurrections, inability to secure labor
                    or inability to secure materials, including inability to
                    secure materials by reason of allocations promulgated by
                    authorized governmental agencies, epidemics, landslides,
                    lightning, earthquakes, fire, storms, floods, washouts,
                    inclement weather which necessitates extraordinary measures
                    and expense to construct facilities and/or maintain
                    operations, explosions, breakage or accident to machinery or
                    lines of pipe, freezing of pipelines, inability to obtain or
                    delays in obtaining easements or rights-of-way, the making
                    of repairs or alterations to pipelines or plants, or any
                    other cause, whether of the kind herein enumerated or
                    otherwise, not reasonably within the control of the Party
                    claiming force majeure.

               14.3 Non-Force Majeure Situations. Neither Operator nor
                    Partnership shall be entitled to the benefit of the
                    provisions of Section 14.1 of this Agreement under the
                    following circumstances:

                    14.3.1 To the extent that the failure was caused by the
                           Party claiming suspension having failed to remedy the
                           condition by taking all reasonable acts, short of
                           litigation, if such remedy requires litigation, and
                           having failed to resume performance of such
                           commitments or obligations with reasonable dispatch;

                                       35
<PAGE>

                    14.3.2 If the failure was caused by failure of the Party
                           claiming suspension to request or pay necessary funds
                           in a timely manner, or with respect to the payment of
                           any amounts then due hereunder;

                    14.3.3 To the extent that the failure was caused or
                           contributed to by the gross negligence or willful
                           misconduct of the Party claiming suspension.

               14.4 Resumption of Normal Performance. Should there be an event
                    of force majeure affecting performance hereunder, the
                    Parties shall cooperate to take all reasonable steps to
                    remedy such event with all reasonable dispatch to insure
                    resumption of normal performance.

               14.5 Strikes and Lockouts. Settlement of strikes and lockouts
                    shall be entirely within the discretion of the party
                    affected, and the requirement in Sections 14.3.1 and 14.4 of
                    this Agreement that any event of force majeure shall be
                    remedied with all reasonable dispatch shall not require the
                    settlement of strikes or lockouts by acceding to the demands
                    of the parties directly or indirectly involved in such
                    strikes or lockouts when such course is inadvisable in the
                    discretion of the party having such difficulty.

               15.2 Notices. Unless otherwise specifically provided in this
                    Agreement, any written notice or other communication shall
                    be sufficiently given or shall be deemed given on the fifth
                    (5th) business day following the date on which the same is
                    mailed by registered or certified mail, postage prepaid,

                           Partner by written notice to Operator. Any Partner
                           may request that additional copies of notices be
                           given to an Affiliate of such Partner at such address
                           as is designated by such Partner by written notice to
                           Operator; provided, however, that any failure to give
                           such notice shall not affect the validity of any
                           notice given to any Partner or the Partnership in
                           accordance with this Section 15.2. Operator agrees to
                           give such notice to any such Affiliate.

               15.3 Counterparts. This Agreement may be executed in
                    counterparts, each of which shall be deemed an original, but
                    all of which together shall constitute one and the same
                    instrument.

               15.4 Headings. The headings contained in this Agreement are for
                    reference purposes only and shall not affect the meaning or
                    interpretation of this Agreement.

               15.5 Waiver. No waiver by any Party of any default by any other
                    Party in the performance of any provision, condition or
                    requirement herein shall be deemed to be a waiver of, or in
                    any manner release the other Party from, performance of any
                    other provision, condition or requirement herein, nor shall
                    such waiver be deemed to be a waiver of, or in any manner a
                    release of, the other Party from future performance of the
                    same

                                       38
<PAGE>

                    provision, condition or requirement. Any delay or omission
                    of any Party to exercise any right hereunder shall not
                    impair the exercise of any such right, or any like right,
                    accruing to it thereafter. No waiver of a right created by
                    this Agreement by one Party shall constitute a waiver of
                    such right by the other Party except as may otherwise be
                    required by law with respect to Persons not parties hereto.
                    The failure of one Party to perform its obligations
                    hereunder shall not release the other Party from the
                    performance of such obligations.

               15.6 Assignability. This Agreement shall not be assigned by
                    either Partnership or Operator, without the written consent
                    of the other, which consent shall not be unreasonably
                    withheld by either Party, provided, however, that either
                    Party may assign this Agreement to a corporation which is an
                    Affiliate of the transferor on the same terms and conditions
                    specified in Section 11.3.1 of the Partnership Agreement for
                    a transfer by a Partner of its interest in the Partnership
                    Agreement, which provisions are incorporated herein by
                    reference as if set out in full (the Party which is not
                    seeking to transfer its interest in the Operating Agreement
                    shall determine whether the conditions set forth in Sections
                    11.3.1(a) and (b) have been satisfied), and further provided
                    that the licenses granted by the individual Partners in
                    Section 7.3 of this Agreement shall not be subject to
                    assignment. Any assignment hereunder shall be effective on
                    the first

                                       39
<PAGE>

                    Day of the Month following the month during which the
                    assignment is completed. This Agreement and all of the
                    obligations and rights herein established shall extend to
                    and be binding upon and shall inure to the benefit of the
                    respective successors and assigns of the respective Parties
                    hereto.

               15.7 References to Money. All references in this Agreement to,
                    and transactions hereunder in, money shall be to or in
                    Dollars of the United States of America.

               15.8 Severability. Should any provision of this Agreement be
                    deemed in contradiction with the laws of any jurisdiction in
                    which it is to be performed or unenforceable for any reason,
                    such provision shall be deemed null and void, but this
                    Agreement shall remain in force in all other respects.
                    Should any provision of this Agreement be or become
                    ineffective because of changes in applicable laws or
                    interpretations thereof or should this Agreement fail to
                    include a provision that is required as a matter of law, the
                    validity of the other provisions of this Agreement shall not
                    be affected thereby. If such circumstances arise, the
                    Parties hereto shall negotiate in good faith appropriate
                    modifications to this Agreement to reflect those changes
                    that are required by law.

                     construed to confer upon or to give any Person not a Party
                     hereto any rights or remedies under or by reason of this
                     Agreement.

               15.10 Laws and Regulatory Bodies. This Agreement and the
                     obligations of the Parties hereunder are subject to all
                     applicable laws, rules, orders and regulations of
                     governmental authorities having jurisdiction and, in the
                     event of conflict, such laws, rules, orders and regulations
                     of governmental authorities having jurisdiction shall
                     control.

               15.11 Remedies Cumulative. Remedies provided under the provisions
                     of this Agreement shall be cumulative and, except as to the
                     agreement for binding arbitration contained in Section 13
                     hereof, shall be in addition to the remedies provided by
                     law or in equity.

               15.12 Conflicts. In the event there is any conflict between this
                     Agreement and any schedule or subsequent agreement referred
                     to herein, the provisions hereof shall be deemed
                     controlling, except in the event of a conflict with the
                     Partnership Agreement, in which event the Partnership
                     Agreement shall be deemed controlling.

               15.13 Approval of Partnership or Management Committee. Unless
                     otherwise specified, when the approval or other action of
                     the Partnership is

                     required under this Agreement such requirement shall be
                     deemed to require approval of the Management Committee
                     pursuant to the provisions of Section 9 of the Partnership
                     Agreement, provided, however, that, if the Operator or an
                     Operator Affiliate is a Partner, approval of actions to be
                     taken by the Partnership against or with respect to the
                     Operator under Sections 5.3, 5.5, 10.1.2, 13.2.1, 13.2.2 of
                     this Agreement shall require approval by vote of 65 percent
                     or more of the total Percentage Interests of the Partners
                     (voting individually and not as members of any bloc) other
                     than: (i) the Operator or its Affiliate and (ii) any
                     Partner which is, or the Affiliate of which is, a
                     subcontractor of the Operator under this Agreement. It is
                     not intended that ownership of the Operator by the
                     Partnership shall cause any Partner to be deemed to be an
                     Affiliate of the Operator for any purpose hereunder or
                     otherwise. Unless otherwise specified, when approval or
                     other action of the Management Committee is required under
                     this Agreement, Section 9 of the Partnership Agreement
                     shall govern such approval.

                     office or offices to perform its obligations hereunder.

                     Section numbers are to Sections of this Agreement.
