paragraph (b) cause the Commitments of the Lenders under this Agreement to
become Dormant on the date specified by the Borrower in such written notice
(the "Commitment Dormancy Date"). Upon receipt of such written notice, from
the Commitment Dormancy Date until such time as the Commitments of the Lenders
are made Active by the Lenders holding Commitments in accordance with paragraph
(c) below, the Commitments of the Lenders under this Agreement shall become
Dormant. While the Commitments of the Lenders under this Agreement are
Dormant, the Borrower may not request extensions of credit under this Agreement
and all Events of Default occurring under this Agreement shall be suspended
(other than the Events of Default specified in Section 6.1(a) and any Events of
Default resulting from the failure of the Borrower to perform the covenants of
the Borrower in Sections 4.1, 4.2(a), 4.2(c), 4.2(e), 4.2(g), or 4.6, which
shall remain in full force and effect subject to applicable cure periods).
Events of Default under this Agreement occurring prior to the Commitment
Dormancy Date are not suspended and the suspension of Events of Default does
not imply any waiver thereof. The suspension of Events of Default while the
Commitments of the Lenders under this Agreement are Dormant shall not suspend
the obligation of the Borrower or any other Loan Party to comply with the terms
of this Agreement and the other Loan Documents, i.e. the Borrower and the other
Loan Parties remain obligated to pay the standby fee and other fees thereunder,
remain liable on their respective indemnity obligations thereunder, and remain
liable on their respective other obligations thereunder, but rather shall serve
solely as a limitation on the existence of an "Event of Default" for the
purposes of this Agreement and therefore a limitation on the specified remedies
set forth under this Agreement and the Loan Documents which relate thereto. If
any event should occur which would have been an Event of Default under Section
6.1(g) but for the suspension of Events of Default, the commitments of the
Agent and the Lenders hereunder, including the Commitments, shall terminate.
If any event should occur which would have been an Event of Default but for the
suspension of Events of Default, the Majority Lenders with Commitments may
declare all of the commitments of the Agent and the Lenders hereunder,
including the Commitments, terminated, whereupon the same shall immediately
terminate.

(c) If the Commitments of the Lenders under this
Agreement are Dormant, the Borrower may by providing written request to the
Agent and the Lenders referencing this paragraph (c) request that the Lenders
holding Commitments make the Commitments of the Lenders under this Agreement
Active. Such request shall be given not later than 30 days prior to the date
proposed by the Borrower on which the Commitments of the Lenders under this
Agreement would become Active (such date or any other date agreed to by the
Lenders holding Commitments and the Borrower when the Commitments of the
Lenders under this Agreement

-18-
25
become Active being the "Commitment Activation Date"). Each such request shall
include therewith all information the Borrower wishes the Lenders with
Commitments to review to determine the financial condition and business
prospects of the Borrower and the capacity of the Borrower and the other Loan
Parties to comply with this Agreement and the other Loan Documents, together
with any waivers the Borrower requests regarding compliance with this Agreement
and the other Loan Documents. The Agent, on behalf of the Lenders with
Commitments, may request such additional information regarding the Borrower as
the Lenders with Commitments determine is reasonably necessary to make their
discretionary determination regarding the request. Within ten Business Days
after the receipt of all requested information, the Agent shall arrange a
meeting of the Lenders with Commitments and the Borrower to review the request.
Each Lender with Commitments and the Borrower shall make representatives
available at the request of the Agent for such purposes. After such meeting,
each Lender with Commitments shall within five Business Days give the Agent
written notice of such Lender's determination of whether or not the Commitments
of the Lenders under this Agreement should become Active in accordance with the
Borrower's request. Each Lender with Commitments shall make such determination
in its own discretion and based upon such factors as such Lender in its own
discretion determines to be relevant. If each Lender with Commitments
determines that the Commitments of the Lenders under this Agreement should
become Active, then the Agent shall so notify the Borrower and on the
Commitment Activation Date, the Commitments of the Lenders under this Agreement
shall become Active. In all other cases, the Commitments of the Lenders under
this Agreement shall remain Dormant. When the Commitments of the Lenders under
this Agreement become Active, the Borrower may request extensions of credit
under this Agreement in accordance with the terms of this Agreement and the
suspension of Events of Default under this Agreement shall cease and such
Events of Default shall resume in accordance with the terms of this Agreement.
With respect to events which occurred while the Commitments of the Lenders
under this Agreement were Dormant which would have been Events of Default under
this Agreement but for the suspension of such Events of Default in accordance
with paragraph (b) above, then effective as of the Commitment Activation Date
such events shall be Events of Default when the Commitments of the Lenders
under this Agreement become Active, unless waived by each Lender.

(d) The Borrower may by providing written request
to the Agent and the Lenders referencing this paragraph (d) request that the
Lenders with Commitments reduce ratably in part or terminate in whole the
Commitments. Such request shall be given not later than 10 days prior to the
date proposed by the Borrower on which the Commitments would be reduced or
terminated and shall specify the amount of the reduction or the termination and
shall be irrevocable and binding on the Borrower. Partial reductions shall be
in a minimum amount of $5,000,000 and be made in integral multiples of
$1,000,000. The Commitments cannot be reduced below the aggregate outstanding
principal amount of Loans. Any reduction or termination of the Commitments
pursuant to this paragraph (d) shall be permanent, with no obligation of the
Lenders to reinstate such Commitments.

Section 2.2 Advancing.

(a) In connection with any circumstances where
the Borrower desires a Loan in an amount equal to or less than $20,000,000
(other than Loans where the proceeds of the Loan shall be used for the purpose
of financing or refinancing an Acquisition outside of the natural gas
compression and production equipment industries, as reasonably determined by
the Agent after consultation with the Borrower) and provided that no other
request under this Section 2.2(a) has been made in connection with the same
circumstances or within the last three months, the Borrower may request the
Lenders with Commitments to advance a Loan for such purposes by providing a
Loan Request for such proposed Loan to the Agent not later than ten Business
Days prior to the proposed date for the Loan. Each Loan Request shall be fully
completed, shall specify the information required therein, and shall have
attached thereto reasonably detailed information regarding the circumstances
related to the Loan Request and all information necessary for the Agent to
determine whether or not the conditions precedent for the advance of additional
credit specified in Sections 7.1, 7.2, and 7.3 (to the extent applicable) are
satisfied. During the first five Business Days after receipt of the Loan
Request, at the request of the Agent, the Borrower shall provide the Agent with
such additional information as the Agent may reasonably request to determine
the satisfaction of such conditions precedent. Upon receipt of all such
requested information the Borrower shall provide the Agent with such additional
time as the Agent may reasonably request to review such additional information,
but in no event less than five Business Days, it being understood that
additional time may be necessary for the Agent to make the determinations
required in connection with the making of the Loan. Each requested Loan must
be in an initial principal amount equal to or greater than $10,000,000. The
Agent shall promptly forward a copy of the Loan Request and any additional
information requested to the Lenders. After consulting with the Lenders and
the Borrower, the Agent shall determine whether or not such conditions
precedent are satisfied, and such determination shall bind all of the Lenders.
The Agent shall promptly inform the Lenders and the Borrower of the
determination of the Agent as to whether or not such conditions precedent are
satisfied. If the Agent determines that such conditions precedent are
satisfied, the Agent shall prepare Notes representing the terms of the Loan for
the Lenders with Commitments and shall provide such Notes to the Borrower for
execution.

(b) In all circumstances where the Borrower
desires a Loan other than those set forth in the first sentence of paragraph
(a) above, the Borrower may request the Lenders with Commitments to advance a
Loan for such purposes by providing a Loan Request for such proposed Loan to
the Agent not later than ten Business Days prior to the proposed date for the
Loan. Each Loan Request shall be fully completed, shall specify the
information required therein, and shall have attached thereto reasonably
detailed information regarding the circumstances related to the Loan Request
and all information reasonably necessary for the Agent and the Lenders to
determine whether or not the conditions precedent for the advance of additional
credit specified in Sections 7.1, 7.2, and 7.3 (to the extent applicable) are
satisfied. During the first five Business

-20-
27
Days after receipt of the Loan Request (or any subsequent information provided
to the Agent at the Agent's request as provided for herein), at the request of
the Agent, the Borrower shall provide the Agent with such additional
information as the Agent may reasonably request to determine the satisfaction
of such conditions precedent. Upon receipt of all such requested information
the Borrower shall provide the Agent with such additional time as the Agent may
reasonably request to review such additional information, but in no event less
than ten Business Days, it being understood that additional time may be
necessary for the Agent and the Lenders to make the determinations required in
connection with the making of the Loan. Each requested Loan must be in an
initial principal amount equal to or greater than $10,000,000. The Agent shall
promptly furnish copies of such Loan Request and any additional information
requested to the Lenders, and arrange for a meeting of the Lenders and the
Borrower to review the Loan Request. Each Lender and the Borrower shall make
representatives available at the request of the Agent to review the Loan
Request. After meeting with the Lenders and the Borrower, the Majority Lenders
for Borrowing shall determine whether or not such conditions precedent are
satisfied, and such determination shall bind all of the Lenders. The Agent
shall promptly inform the Lenders and the Borrower of the determination of the
Majority Lenders for Borrowing of whether or not such conditions precedent are
satisfied. If the Majority Lenders for Borrowing determine that such
conditions precedent are satisfied, the Agent shall prepare Notes representing
the terms of the proposed Loan for the Lenders with Commitments and shall
provide such Notes to the Borrower for execution.

(c) If under paragraph (a) above the Agent has
determined, or under paragraph (b) above the Majority Lenders for Borrowing
have determined, that the required conditions are satisfied, each Lender
holding Commitments shall, before 2:00 p.m. (Houston, Texas, time) on the date
of the requested Loan make available from its Applicable Lending Office to the
Agent at the Agent's Applicable Lending Office, in immediately available funds,
such Lender's ratable share of such Loan. After receipt by the Agent of such
funds, the Agent shall before close of business on the date requested for such
Loan make such Loan available to the Borrower in immediately available funds at
the Borrower Account.

(d) Unless the Agent shall have received notice
from a Lender holding Commitments before the date of any Loan that such Lender
shall not make available to the Agent such Lender's ratable share of such Loan,
the Agent may assume that such Lender has made its ratable share of such Loan
available to the Agent on the date of such Loan in accordance with paragraph
(c) above and the Agent may, in reliance upon such assumption, make available
to the Borrower on such date a corresponding amount. If and to the extent that
such Lender shall not have so made its ratable share of such Loan available to
the Agent, such Lender agrees that it shall pay interest on such amount for
each day from the date such amount is made available to the Borrower by the
Agent until the date such amount is paid to the Agent by such Lender at the
Adjusted Prime Rate in effect from time to time provided that if such amount is
not paid by such Lender by the end of the second day after the Agent makes such
amount available to the Borrower,

-21-
28
the interest rates specified above shall be increased by a per annum amount
equal to 2.00% on the third day and shall remain at such increased rate
thereafter. Interest on such amount shall be due and payable by such Lender
upon demand by the Agent. If such Lender shall pay to the Agent such amount
and interest as provided above, such amount so paid shall constitute such
Lender's Advance as part of such Loan for all purposes of this Agreement even
though not made on the same day as the other Advances comprising such Loan. In
the event that such Lender has not repaid such amount by the end of the fifth
day after such amount was made available to the Borrower, the Borrower agrees
to repay to the Agent on demand such amount, together with interest on such
amount for each day from the date such amount was made available to the
Borrower until the date such amount is repaid to the Agent at the interest rate
charged to the Borrower for such Loan under the terms of this Agreement.

(e) The failure of any Lender holding Commitments
to make available its ratable share of any Loan shall not relieve any other
Lender holding Commitments of its obligation, if any, to make available its
ratable share of such Loan. No Lender shall be responsible for the failure of
any other Lender to honor such other Lender's obligations hereunder, including
any failure to make available any funds as part of any Loan.

Section 2.3 Prepayment.

(a) Unless expressly stated otherwise in any
Note, the Borrower may prepay to the Agent, for the ratable benefit of the
holders of an interest in any Loan, the outstanding principal amount of such
Loan pursuant to written notice given by the Borrower to the Agent not later
than the fifth Business Day before the date of the proposed prepayment, such
prepayments to be without premium or penalty except as set forth in the Loan
Documents. All voluntary prepayments under this paragraph (a) must be made on
a Payment Date. Each such notice shall specify the Loan to be prepaid, the
amount of the prepayment, and the Payment Date for the prepayment and shall be
irrevocable and binding on the Borrower. Prepayments of Loans shall be made in
a minimum amount of $1,000,000 or if the prepayment would cause the outstanding
principal amount of the Loan being prepaid to be less than $5,000,000, the
prepayment must be in the entire outstanding principal amount of such Loan.
Upon receipt of any notice of prepayment, the Agent shall give prompt notice of
the intended prepayment to the Lenders holding an interest in such Loan. For
each such notice given by the Borrower, the Borrower shall prepay the specified
Loan in the specified amount on the specified date as set forth in such notice.
The Borrower shall have no right to prepay any principal amount of any Loan
except as provided in the corresponding Notes or in this subsection 2.3(a).
Each prepayment of principal on any Loan pursuant to this subsection 2.3(a)
shall be accompanied by payment of all accrued but unpaid interest on the
principal amount prepaid and any amounts required to be paid pursuant to
Section 2.9 as a result of such prepayment. All prepayments pursuant to this
subsection 2.3(a) shall be applied to the required payments of principal on the
Loan being prepaid in the inverse order of maturity.

-22-
29

the ratable benefit of the Lenders holding an interest in each Loan, the
outstanding principal amount of each Loan in accordance with the prepayment
requirements of the corresponding Notes, if any.

(d) If there shall occur any Change of Control,
the Borrower shall prepay to the Agent, for the ratable benefit of the Lenders
holding an interest in the Loans, upon written demand of the Majority Lenders

written notice from the Majority Lenders with Commitments, the Commitments of
the Lenders shall be terminated). Each prepayment of principal on the Loans
pursuant to this subsection 2.3(d) shall be accompanied by payment of all
accrued but unpaid interest on the principal amount prepaid and any amounts
required to be paid pursuant to Section 2.9 as a result of such prepayment.

(e) If the Collateral Trustee shall hold as
collateral any proceeds resulting from the sale of any natural gas compressors
or oil and gas production equipment and such proceeds are applied to the
secured obligations under the Collateral Trust Agreement in accordance with the
Collateral Trust Agreement, the Borrower shall prepay to the Agent, for the
ratable benefit of the Lenders holding an interest in the Loans, the
outstanding principal amount of the Loans under this Agreement in an amount
equal to the amount of such application allocated to the Agent and the Lenders
under the Collateral Trust Agreement. Each prepayment of principal on Loans
pursuant to this subsection 2.3(e) shall be accompanied by payment of all
accrued but unpaid interest on the principal amount prepaid and any amounts
required to be paid pursuant to Section 2.9 as a result of such prepayment.
All prepayments required pursuant to this subsection 2.3(e) shall be applied to
the Loans ratably in accordance with the outstanding principal amount of each
Loan, and shall be applied to the required payments of principal on each Loan
being prepaid in the inverse order of maturity.

(f) If the Collateral Trustee shall hold as
collateral any proceeds resulting from any business interruption, casualty, or
condemnation, including, without limitation, any business interruption
insurance proceeds, any property insurance proceeds, or any condemnation
proceeds, and such proceeds are applied to the secured obligations under the
Collateral Trust Agreement in accordance with the Collateral Trust Agreement,
the Borrower shall prepay to the Agent, for the ratable benefit of the Lenders
holding an interest in the Loans, the outstanding principal amount of the Loans
under this Agreement in an amount equal to the amount of such application
allocated to the Agent and the Lenders under the Collateral Trust Agreement.
Each prepayment of principal on Loans pursuant to this subsection 2.3(f) shall
be accompanied by payment of all accrued but unpaid interest on the principal
amount prepaid and any amounts required to be paid pursuant to Section 2.9 as a
result of such prepayment. All prepayments required pursuant to this
subsection 2.3(f) shall be applied to the Loans ratably in accordance with

-23-
30
the outstanding principal amount of each Loan, and shall be applied to the
required payments of principal on each Loan being prepaid in the inverse order
of maturity.

(g) If during the existence of a Default or Event
of Default the Collateral Trustee shall make any distribution to the Agent or
the Lenders under the Collateral Trust Agreement, the Borrower shall prepay to
the Agent for the ratable benefit of the Lenders holding an interest in the
Loans, the outstanding principal amount of the Loans under this Agreement in an
amount equal to the amount of such distribution to the Agent and the Lenders
under the Collateral Trust Agreement. Each prepayment of principal on Loans
pursuant to this subsection 2.3(g) shall be accompanied by payment of all
accrued but unpaid interest on the principal amount prepaid and any amounts
required to be paid pursuant to Section 2.9 as a result of such prepayment.

the Loans ratably in accordance with the outstanding principal amount of each

being prepaid in the inverse order of maturity.

Section 2.4 Repayment.

(a) For each Loan, the corresponding Notes shall
set forth the principal repayment schedule selected for such Loan by the
Borrower provided that (i) payments shall be due only on Payment Dates, (ii)
the Loan Maturity Date for such Loan shall not exceed seven years from the date
of the making of such Loan and shall not exceed the Final Maturity Date, and
(iii) after taking into account the scheduled principal payments on such Loan,
the consolidated scheduled principal payments on Indebtedness of the Borrower
and its Qualified Subsidiaries during each year while any Loans will remain
outstanding (other than scheduled principal payments under revolving credit
facilities of the Borrower and its Qualified Subsidiaries during such period
resulting from the maturity of such revolving credit facilities to the extent
such scheduled principal payments are reasonably expected to be extended,
renewed, rearranged, or refinanced under revolving credit facilities maturing
beyond such period) cannot exceed the greater of (x) 65% of the Consolidated

the Agent Fee Letter in accordance with the confidential terms of the Agent Fee
Letter.

(b) (i) During any period while the Commitments
of the Lenders under this Agreement exceed $50,000,000, the Borrower shall pay
to the Agent, for the ratable benefit of the Lenders holding Commitments, a
standby fee equal to 0.50% per annum on the average daily amount by which
$50,000,000 exceeds the aggregate outstanding principal amount of the Loans and
an additional standby fee equal to 0.25% per annum on the average daily amount
by which the aggregate amount of the Commitments exceeds $50,000,000; provided,
however, that in the event that the aggregate outstanding principal amount of
the Loans ever exceeds $50,000,000, retroactively beginning as of January 1 of
the year during which the aggregate outstanding principal amount of the Loans
exceeds $50,000,000, the Borrower shall instead pay to the Agent, for the
ratable benefit of the Lenders holding Commitments, a standby fee equal to
0.50% per annum on the average daily amount by which the aggregate amount of
the Commitments exceeds the aggregate outstanding principal amount of the Loans
and (ii) during any period while the Commitments of the Lenders under this
Agreement are equal to or less than $50,000,000, the Borrower shall pay to the
Agent, for the ratable benefit of the Lenders holding Commitments, a standby
fee equal to 0.50% per annum on the average daily amount by which the aggregate

date of this Agreement through the Drawdown Termination Date and shall be due
and payable in arrears on the last day during each calendar quarter and on the
Drawdown Termination Date.

Section 2.6 Interest.

(a) Under the Loan Request provided to the Agent
in connection with the making of each Loan, the Borrower shall select such Loan
to accrue interest as a LIBOR Rate Loan or a Prime Rate Loan.

(b) For each Loan, the corresponding Notes shall
state that the Borrower may from time to time select such Loan to accrue
interest as either a LIBOR Rate Loan or a Prime Rate Loan by giving the Agent
four Business Days advance notice of the Borrower's intent to convert the
interest rate basis of such Loan.

(i) The corresponding Notes shall state
that while such Loan is bearing interest as a LIBOR Rate Loan (A) such
LIBOR Rate Loan shall bear interest during each Interest Period
selected by the Borrower in writing at a per annum interest rate equal
to the sum of the applicable LIBOR for such Interest

-25-
32
Period plus the Applicable Margin for such LIBOR Rate Loan, (B) the
Borrower may select each successive Interest Period for such LIBOR
Rate Loan at any time four or more Business Days prior to the end of
the then current Interest Period for such LIBOR Rate Loan by giving
written notice thereof to the Agent, (C) the Borrower shall pay to the
Agent, for the ratable benefit of the Lenders holding an interest in
such LIBOR Rate Loan, all accrued but unpaid interest on such LIBOR
Rate Loan thereunder on the last day of each Interest Period for such
LIBOR Rate Loan (and with respect to any LIBOR Rate Loan with an
Interest Period of greater than three months, on the date which is
three months after the first date of the Interest Period for such
LIBOR Rate Loan), on any date when such LIBOR Rate Loan is converted
to a Prime Rate Loan, on any date when such LIBOR Rate Loan is prepaid
in full, and on the applicable Loan Maturity Date for such Loan, and
(D) if the Borrower has not selected or cannot select any Interest
Period for the LIBOR Rate Loan in accordance with the foregoing, the
Borrower shall be deemed to have elected to convert such LIBOR Rate
Loan to a Prime Rate Loan at the end of the then current Interest
Period.

(ii) The corresponding Notes shall state
that while such Loan is bearing interest as a Prime Rate Loan (A) such
Prime Rate Loan shall bear interest at a per annum interest rate equal
to the sum of the Adjusted Prime Rate in effect from time to time plus
the Applicable Margin for such Prime Rate Loan and (B) the Borrower
shall pay to the Agent, for the ratable benefit of the Lenders holding
an interest in such Prime Rate Loan, all accrued but unpaid interest
on such Prime Rate Loan on the last day of each calendar quarter while
such Prime Rate Loan is outstanding, on any date when such Prime Rate
Loan is converted to a LIBOR Rate Loan, on any date when such Prime
Rate Loan is prepaid in full, and on the applicable Loan Maturity Date
for such Loan.

(c) The Borrower shall pay to the Agent, for the
ratable benefit of the Lenders holding an interest in each Loan, all accrued
but unpaid interest on the outstanding principal amount of such Loan in
accordance with the terms of the corresponding Notes. The Borrower shall pay
to the Agent, for the ratable benefit of the Lenders holding an interest in the
Loans, all accrued but unpaid interest on the aggregate outstanding principal
amount of all Loans on the Final Maturity Date.

Affiliates shall enter into Derivative agreements with the Borrower hedging the
interest rate risk related to any Loan for the Borrower on terms mutually
satisfactory to JEDI or its Affiliates and the Borrower.

(e) If on any date the applicable interest rates
on the consolidated Indebtedness of the Borrower and its Qualified Subsidiaries
have increased such that, if such increased interest rates had been in effect
during the previous four fiscal quarters of the Borrower, then the Consolidated
Fixed Charge Coverage Ratio of the Borrower and its Qualified Subsidiaries for
such previous four fiscal quarters, recomputed as if such rates had been in
effect during such previous four fiscal quarters (and after taking into account
the hedging effect of the interest rate

-26-
33
Derivatives held by the Borrower and its Qualified Subsidiaries which would
have occurred during the previous four fiscal quarters of the Borrower had such
rates been in effect), would have been reduced by 10%, upon written request of
the Agent the Borrower shall enter into such Derivative agreements permitted by
Section 5.9 as reasonably requested by the Agent to reduce or remove any
further interest rate risk of the Borrower and its Qualified Subsidiaries.

Section 2.7 Records, Payments, and Computations.

(a) To evidence each Advance made by a Lender as
part of a Loan made under this Agreement, the Borrower will issue, execute, and
deliver to such Lender a Note in the amount of such Advance. Each time an
Advance is made or a payment is received, each Lender holding a Note is hereby
irrevocably authorized by the Borrower to make an appropriate notation on a
ledger forming a part of such Note reflecting the amount loaned or paid and the
date thereof; provided however, the failure of any Lender to do so shall not
relieve the Borrower or any other liable party of its liability hereunder or
under such Note or subject the Borroweror any other liable party to additional
liability under such Note. Furthermore, each Lender holding a Note is hereby
irrevocably authorized by the Borrower to attach to and to make a part of such
Note a continuation of any such schedule of the Advance and payments, as and
when required, reflecting the amount paid and the date of such payment. The
aggregate unpaid amount of the Advance under any Note reflected by the
notations by the applicable Lender in its records or a ledger sheet or sheets
affixed to such Note shall be deemed conclusive evidence thereof, absent
manifest error, of the principal amount owing on such Note. The liability for
payment of principal and interest evidenced by each Note shall be limited to
the principal amounts actually loaned and outstanding under such Note and this
Agreement and interest on such amounts calculated in accordance with such Note
and this Agreement.

(b) All payments and prepayments made by or on
behalf of the Borrower under the Loan Documents, including payments made under
the Collateral Trust Agreement, shall be made by wire transfer in immediately
available funds before 12:00 noon (Houston, Texas, time) on the date such
payment is required to be made to the Applicable Payment Office for the Agent.
Any payment received and accepted by the Agent after such time shall be
considered for all purposes, including the calculation of interest, as having
been made on the Agent's next following Business Day. All payments by the
Borrower shall be made without any offset, abatement, withholding, or
reduction. All payments and prepayments allocable to the Agent or the Lenders
under the Collateral Trust Agreement shall be paid directly to the Applicable
Payment Office for the Agent. Any amounts received by any Lenders in violation
of the foregoing shall be held by such Lender in trust for the Agent and
promptly paid over to the Agent (with any necessary endorsement).

(c) Upon receipt of payment from the Borrower of
any principal, interest, or fees due to the Lenders, the Agent shall promptly
after receipt thereof distribute to the

-27-
34
Lenders their ratable share of such payments for the account of their
respective Applicable Payment Offices. Upon receipt of other amounts due
solely to the Agent or a specific Lender, the Agent shall distribute such
amounts to the appropriate party to be applied in accordance with the terms of
this Agreement.

(d) Unless the Agent shall have received written
notice from the Borrower prior to any date on which any payment is due from the
Borrower under this Agreement and the Loan Documents that the Borrower shall
not make such payment in full, the Agent may assume that the Borrower has made
such payment in full to the Agent on such date and the Agent may, in reliance
upon such assumption, cause to be distributed to each Lender that is due
payment on such date an amount equal to the amount then due to such Lender. If
and to the extent the Borrower shall not have so made such payment in full to
the Agent, each Lender receiving payment shall repay to the Agent forthwith on
demand such amount distributed to such Lender, together with interest thereon
from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Agent, at an interest rate equal to the
Adjusted Prime Rate in effect from time to time provided that if such amount is
not repaid by such Lender by the end of the second day after the date of the
Agent's demand, the interest rates specified above shall be increased by a per
annum amount equal to 2.00% on the third day after the date of the Agent's
demand and shall remain at such increased rate thereafter.

(e) Each Lender agrees that if it should receive
any payment (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Loan Documents, or otherwise)
in respect of any obligation of the Borrower to pay principal, interest, or
fees incurred under the Loan Documents in a proportion greater than the total
amount of such principal, interest, or fees then due by the Borrower to such
Lender bears to the total amount of principal, interest, or fees then due by
the Borrower to all of the Lenders which are owed such principal, interest, or
fees immediately prior to such receipt, then such Lender receiving such excess
payment of principal, interest, or fees, as the case may be, shall purchase for
cash without recourse from the other Lenders which are due such principal,
interest, or fees an interest in such principal, interest, or fees owed by the
Borrower to such Lenders in such amount as shall result in a proportional
participation by all of the Lenders which are due such principal, interest, or
fees in the aggregate unpaid amount of principal, interest, or fees owed by the
Borrower to such Lenders; provided that if all or any portion of such excess
payment is thereafter recovered from such Lender, such purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest.

(f) [Reserved].

(g) Unless expressly provided for in this
Agreement or in any Note, (i) all computations of interest based on the Prime
Rate shall be made on the basis of a 365/366 day

-28-
35
year, as the case may be, (ii) all computations of interest based on the
Federal Funds Rate shall be made on the basis of a 360 day year, (iii) all
computations of interest based upon the LIBOR shall be made on the basis of a
360 day year, and (iv) all computations of fees shall be made on the basis of a
365/366 day year. All such computations shall be made for the actual number of
days (including the first day, but excluding the last day) occurring in the
period for which such computation is being performed. Interest provided for
under this Agreement and the Notes shall be calculated on the unpaid sums
actually loaned and outstanding pursuant to the terms of this Agreement and the
applicable Notes and only for the period from the date or dates advanced until
repaid. Each determination by the Agent of an interest rate or fee shall be
conclusive and binding for all purposes, absent manifest error.

(h) Whenever any payment under any Loan Document
shall be stated to be due on a day other than a Business Day, such payment
shall be made on the next succeeding Business Day. In either case, such
extension of time shall be included in the computation of the payment of
interest, fees, or such other amount due on the outstanding amount. If the
time for payment for an amount payable is not specified in any Loan Document,
the payment shall be due and payable ten days after the date on which the Agent
demands payment therefor.

Section 2.8 Taxes.

(a) Any and all payments by the Loan Parties
shall be made free and clear of and without deduction for any and all present
or future taxes, levies, imposts, deductions, charges, or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Lender and the
Agent, taxes imposed on its income and franchise taxes imposed on it by any
jurisdiction of which such Lender is a citizen or resident or any political
subdivision of such jurisdiction (all such nonexcluded taxes, levies, imposts,
deductions, charges, withholdings, and liabilities being hereinafter referred
to as "Taxes") and, in the case of each Lender and the Agent, Taxes by the
jurisdiction of such Lender's Applicable Lending Office or any political
subdivision of such jurisdiction. If any Loan Party shall be required by law
to deduct any Taxes from or in respect of any sum payable to each Lender and
the Agent, (i) the sum payable shall be increased as may be necessary so that,
after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.8), such Lender receives an amount
equal to the sum it would have received had no such deductions been made; (ii)
such Loan Party shall make such deductions; and (iii) such Loan Party shall pay
the full amount deducted to the relevant taxation authority or other authority
in accordance with applicable law.

(b) The Borrower agrees to pay and hold the Agent
and each Lender harmless from and against any and all present and future stamp
and other similar taxes with respect to this Agreement and Loan Documents and
save the Agent and each Lender harmless from and against any and all
liabilities with respect to or resulting from any delay or omission to pay such
taxes, and indemnify the Agent and each Lender for the full amount of taxes
paid by the

-29-
36
Agent or such Lender in respect of payments made or to be made under this
Agreement or any other Loan Document and any liability (including penalties,
interest, and expenses) arising therefrom or with respect thereto, whether or
not such taxes were correctly or legally asserted (excluding, in the case of
the Agent and each Lender, taxes imposed on its income and franchise taxes
imposed on it by any jurisdiction of which such Lender is a citizen or resident
or any political subdivision of such jurisdiction).

(c) Each Lender that is not incorporated under
the laws of the United States of America or a state thereof agrees that it
shall deliver to the Borrower and the Agent (i) two duly completed copies of
United States Internal Revenue Service Form 1001 or 4224 or successor
applicable form, as the case may be, certifying in each case that such Lender
is entitled to receive payments under this Agreement and the Notes payable to
it, without deduction or withholding of any United States federal income taxes,
(ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or successor
applicable form, as the case may be, to establish an exemption from United
States backup withholding tax, and (iii) any other governmental forms which are
necessary or required under an applicable tax treaty or otherwise by law to
reduce or eliminate any withholding tax, which have been reasonably requested
by the Borrower. Each Lender which delivers to the Borrower and the Agent a
Form 1001 or 4224 and Form W-8 or W-9 pursuant to the next preceding sentence
further undertakes to deliver to the Borrower and the Agent two further copies
of the said letter and Form 1001 or 4224 and Form W-8 or W-9, or successor
applicable forms, or other manner of certification, as the case may be, on or
before the date that any such letter or form expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent letter
and form previously delivered by it to the Borrower and the Agent, and such
extensions or renewals thereof as may reasonably be requested by the Borrower
and the Agent certifying in the case of a Form 1001 or 4224 that such Lender is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes. The Borrower shall
withhold tax at the rate and in the manner required by the laws of the United
States with respect to payments made to a Lender failing to provide the
requisite Internal Revenue Service forms in a timely manner. If an event
(including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any delivery required by the preceding
sentence would otherwise be required which renders all such forms inapplicable
or which would prevent any Lender from duly completing and delivering any such
letter or form with respect to it and such Lender advises the Borrower and the
Agent that it is not capable of receiving payments without any deduction or
withholding of United States federal income tax, and in the case of a Form W-8
or W-9, establishing an exemption from United States backup withholding tax,
such Lender shall not be required to deliver such letter or forms. Each Lender
which fails to provide to the Borrower in a timely manner such forms shall
reimburse the Borrower upon demand for any penalties paid by the Borrower as a
result of any failure of the Borrower to withhold the required amounts that are
caused by such Lender's failure to provide the required forms in a timely
manner.

-30-
37
(d) Notwithstanding the foregoing paragraphs (a)
through (c) above, before making any demand for payment under this Section 2.8,
each Lender agrees to use commercially reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to designate a different
Applicable Lending Office if the making of such a designation would avoid the
need for, or reduce the amount of, such payments required under this Section
2.8.

Section 2.9 Make-Whole Provisions.

(a) If (i) any payment of principal on or any
conversion of any LIBOR Rate Loan is made on any date other than the last day
of the Interest Period for such LIBOR Rate Loan, whether as a result of any
voluntary or mandatory prepayment, any acceleration of maturity, or any other
cause (other than any regularly scheduled principal repayment), (ii) any
payment of principal on any LIBOR Rate Loan is not made when due, or (iii) any
LIBOR Rate Loan is not borrowed, converted, or prepaid in accordance with the
respective request therefor provided by the Borrower to the Agent, whether as a
result of any failure to meet any applicable conditions precedent for
borrowing, conversion, or prepayment, the permitted cancellation of any request
for borrowing, conversion, or prepayment, the failure of the Borrower to
provide the respective notice of borrowing, conversion, or prepayment, or any
other cause; then in such event the Borrower shall, upon demand of any Lender,
pay to such Lender such amounts as are required to compensate such Lender for
any losses, costs, or expenses which it may reasonably incur as a result of any
such payment or nonpayment, including any lost profits resulting from
liquidation or reinvestment of deposits, equity contributions, or other funds
acquired by such Lender to maintain or fund the LIBOR Rate Loans for the
duration of the applicable Interest Period and all properly documented and
reasonable administrative expenses incurred in connection therewith. A
certificate as to the amount of such losses, costs, or expenses detailing the
calculation thereof prepared by such Lender and submitted to the Borrower shall
be conclusive and binding for all purposes, absent manifest error.

(b) Should the Borrower make any prepayment of
any principal portion of any Loan, whether as a result of any voluntary or
mandatory prepayment, the acceleration of the maturity of the Loan, or
otherwise, then the Borrower shall pay to JEDI or its Affiliates upon demand an
amount sufficient to compensate each such Person which has entered into
Derivatives hedging the interest rate risk allocable to such Loan for any loss,
cost, or expense, including any lost profits and termination penalties,
allocable to the termination of such Derivative. A certificate as to the
amount of such loss, cost, or expense detailing the calculation thereof
prepared by such Person and submitted to the Borrower shall be conclusive and
binding for all purposes, absent manifest error.

-31-
38
Section 2.10 Increased Costs.

(a) Cost of Funds. If, due to either the
introduction of or any change in or in the interpretation, application, or
applicability of any law or regulation, or the compliance with any guideline or
request from any Governmental Authority (whether or not having the force of
law), there shall be any increase in the cost to any Lender of funding or
maintaining Loans, including any increase in any applicable reserve requirement
for LIBOR Rate Loans, or any reduction of such Lender's reasonably anticipated
return on its investment, then the Borrower shall from time to time upon demand
by such Lender pay to such Lender such additional amounts sufficient to
compensate such Lender for such increased cost or reduced return. A
certificate as to the amount of such increased cost or reduced return detailing
the calculation thereof prepared by such Lender and submitted to the Borrower
shall be conclusive and binding for all purposes, absent manifest error.

(b) Capital Adequacy. If due to any change in
any law or regulation or any interpretation, directive, or request of any court
or governmental or monetary authority, whether or not having the force of law,
there shall be any increase by an amount which such Lender reasonably deems to
be material in the capital requirements of any Lender or its parent or holding
company related to its commitments to make or the making, funding, or
maintaining of any Loans hereunder, as such capital requirements are reasonably
allocated by such Lender, then the Borrower shall from time to time upon demand
by such Lender pay to such Lender additional amounts sufficient to compensate
such Lender or its parent or holding company for such increase in costs
(including an amount equal to any reduction of the rate of return on assets or
equity of such Lender or its parent or holding company to a level below that
which such Lender or its parent or holding company could have achieved but for
such change in law, regulation, interpretation, directive, or request). A
certificate as to such amounts and detailing the calculation of such amounts
prepared by such Lender and submitted to the Borrower shall be conclusive and
binding for all purposes, absent manifest error.

Section 2.11 Illegality.

(a) LIBOR Funding. Notwithstanding any other
provision in this Agreement, if it becomes unlawful for any Lender to obtain
deposits or other funds for making or funding of LIBOR Rate Advances in the
London interbank market or other deposits or funds market customarily used by
such Lender, such Lender will so notify the Borrower and such Lender's
obligation to make LIBOR Rate Advances shall be suspended until such condition
has passed and, upon the expiration of the applicable Interest Period for each
LIBOR Rate Loan, or sooner if required by law, such Lender shall convert its
LIBOR Rate Advance which is part of such LIBOR Rate Loan to a Prime Rate
Advance. Such Lender's Advances for all LIBOR Rate Loans requested thereafter
shall be made as and maintained as Prime Rate Advances in accordance with this
Agreement and the applicable Notes.

-32-
39
(b) Generally. Notwithstanding any other
provision in this Agreement, if it becomes unlawful for any Lender to maintain
Advances or to give effect to its obligations hereunder, such Lender will so
notify the Agent and the Borrower, and to the extent necessary to prevent the
violation of law the aggregate outstanding principal amount of Advances made by
such Lender, all accrued but unpaid interest thereon, and any other amounts
payable to such Lender under this Agreement and the other Loan Documents will
be prepaid as provided in such notice, and such Lender's Commitment hereunder
shall be terminated.

Section 2.12 Market Failure. Notwithstanding any other provision
in this Agreement, if the Agent determines that: (a) quotations of interest
rates for the relevant deposits referred to in the definition of "LIBOR" or (b)
the relevant rates of interest referred to in the definition of "LIBOR" which
are used as the basis to determine the rate of interest for LIBOR Rate Loans
are not likely to adequately cover the cost to the Lenders of maintaining such
LIBOR Rate Loans, then the Agent shall give the Borrower prompt notice thereof
and, upon the expiration of the applicable Interest Period for each LIBOR Rate
Loan, such LIBOR Rate Loan shall convert to a Prime Rate Loan. All LIBOR Rate
Loans shall thereafter be made as and maintained as Prime Rate Loans in
accordance with this Agreement and the applicable Notes.

ARTICLE 3

REPRESENTATIONS AND WARRANTIES

In order to induce the Agent and the Lenders to enter into this
Agreement and to make Loans hereunder, the Borrower represents and warrants to
the Agent and the Lenders on the date hereof, on the date of each Loan Request,
and on the date of each Loan made hereunder that:

Section 3.1 Financial Condition.

(a) The consolidated balance sheets of the
Borrower and its consolidated Subsidiaries as at December 31, 1994, and the
related consolidated statements of income and of cash flows for the fiscal year
ended on such date reported on by Price Waterhouse (the "Financial
Statements"), together with the consolidating schedules used to prepare the
Financial Statements, copies of all of which have heretofore been furnished to
the Agent, are complete and correct and present fairly the financial condition
of the Borrower and its consolidated Subsidiaries as at such dates, and the
results of their operations and cash flows for the fiscal year then ended. The
unaudited consolidated balance sheets of the Borrower and its consolidated
Subsidiaries as at September 30, 1995, and the related unaudited consolidated
statements of income and of cash flows for the fiscal quarter ended on such
date certified to the Agent by a Responsible Officer of the Borrower (the
"Interim Financial Statements"), copies of all of which have heretofore been
furnished to the Agent, are complete and correct and present fairly the
financial condition of the Borrower and its consolidated Subsidiaries as at
such date, and the results of their operations and

-33-
40
consolidated cash flows for the fiscal quarter then ended (subject to normal
year-end audit adjustments).

(b) All such financial statements, including the
related schedules and notes thereto, have been prepared in accordance with GAAP
applied consistently throughout the periods involved (except for changes within
GAAP which are approved by such accountants or Responsible Officer of the
Borrower, as the case may be, and disclosed therein). Except as disclosed in
Schedule II, neither the Borrower nor any of its consolidated Subsidiaries had,
at the date of the Financial Statements or Interim Financial Statements, any
material Guarantee Obligation, contingent liability, or liability for taxes, or
any long-term lease or unusual forward or long-term commitment, including,
without limitation, any interest rate or foreign currency swap or exchange
transaction, which is not reflected in the Financial Statements, the Interim
Financial Statements, or in the notes thereto. Except as disclosed in Schedule
II, during the period from the date of the Financial Statements to and
including the date hereof there has been no sale, transfer, or other
disposition by the Borrower or any of its consolidated Subsidiaries of any
material part of their respective business or property and no purchase or other
Acquisition material in relation to the consolidated financial condition of the
Borrower and its consolidated Subsidiaries as at the date of the Interim
Financial Statements.

(c) The pro forma consolidated balance sheet of
the Borrower certified by the chief financial officer of the Borrower to the
Agent as being the unaudited consolidated balance sheet of the Borrower as of
September 30, 1995, adjusted for the equity transactions completed since such
date and any transactions related thereto, the transactions contemplated by
this Agreement, and the transactions contemplated by the Chemical Credit
Agreement, is, together with the notes thereto, a good faith estimate on a pro
forma basis of the consolidated financial position of the Borrower as of
September 30, 1995, as adjusted as described above assuming that the
transactions specified above had actually occurred on September 30, 1995.

Section 3.2 No Change. Since the date of the Financial
Statements, (a) there has been no development or event nor any prospective
development or event, which has had or would reasonably be expected to have a
Material Adverse Effect and (b) except as disclosed in Schedule II, no
dividends or other distributions have been declared, paid, or made upon the
Capital Stock of the Borrower nor has any of the Capital Stock of the Borrower
been redeemed, retired, purchased, or otherwise acquired for value by the
Borrower or any of its respective Subsidiaries.

Section 3.3 Corporate Existence; Compliance with Law. Each Loan
Party (a) is duly organized, validly existing, and in good standing under the
laws of the jurisdiction of its organization, (b) has the corporate power and
authority, and the legal right, to own and operate its owned property, to lease
the property it operates as lessee, and to conduct the business in which it is
currently engaged, (c) is duly qualified as a foreign corporation and in good
standing under the laws of each jurisdiction where its ownership, lease, or
operation of property or the conduct

-34-
41
of its business requires such qualification, except where the failure to be so
qualified would not reasonably be expected to have a Material Adverse Effect,
and (d) is in compliance with all Requirements of Law except to the extent that
the failure to comply therewith would not, in the aggregate, reasonably be
expected to have a Material Adverse Effect.

Section 3.4 Corporate Power; Authorization; Enforceable
Obligations. Each Loan Party has the corporate power and authority, and the
legal right, to make, deliver, and perform the Loan Documents to which it is a
party and, with respect to the Security Documents to which it is a party, to
grant the Liens pursuant thereto. The Borrower has the corporate power and
authority, and the legal right, to borrow hereunder and has taken all necessary
corporate action to authorize the borrowings on the terms and conditions of
this Agreement and the Loan Documents. Each Loan Party has taken all necessary
corporate action to authorize the execution, delivery, and performance of the
Loan Documents to which it is a party and, with respect to the Security
Documents to which it is a party, to grant the Liens pursuant thereto. Except
for consents and authorizations which have been obtained, filings which have
been made, and other actions which have been taken, no consent or authorization
of, filing with, or other act by or in respect of any Governmental Authority or
any other Person (other than consents under contracts which the failure to
obtain would not, in the aggregate, reasonably be expected to have a Material
Adverse Effect) is required in connection with the borrowings hereunder or with
the execution, delivery, performance, validity, or enforceability of this
Agreement, the Notes, or any of the other Loan Documents or, with respect to
the Security Documents, the granting of the Liens thereunder. This Agreement
and the Loan Documents executed in connection herewith have been, and each Note
and each other Loan Document will be, duly executed and delivered on behalf of
the Loan Parties party thereto. This Agreement and the Loan Documents executed
in connection herewith constitute, and each Note and each other Loan Document
when executed and delivered will constitute, a legal, valid, and binding
obligation of the Loan Parties party thereto enforceable against such Loan
Parties 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).

Section 3.5 No Legal Bar. The execution, delivery, and
performance of this Agreement, the Notes, and the other Loan Documents, the
borrowings hereunder and the use of the proceeds thereof will not violate any
Requirement of Law or Contractual Obligation of any Loan Party thereto and will
not result in, or require, the creation or imposition of any Lien on any of
their respective properties or revenues pursuant to any such Requirement of Law
or Contractual Obligation, except as contemplated hereby or thereby.

Section 3.6 No Material Litigation. No litigation,
investigation, or proceeding by or before any arbitrator or Governmental
Authority is pending or, to the knowledge of the Borrower, threatened by or
against any Loan Party or against any of their respective properties or
revenues

-35-
42
(a) with respect to this Agreement, the Notes, or the other Loan Documents or
any of the transactions contemplated hereby, or (b) which would reasonably be
expected to have a Material Adverse Effect.

Section 3.7 No Default. None of the Loan Parties nor any of
their respective Subsidiaries is in default under or with respect to any of
their respective Contractual Obligations in any respect which if not cured
would reasonably be expected to have a Material Adverse Effect. To the best of
the Borrower's knowledge, no third party is in default under or with respect to
any Contractual Obligation with any Loan Party or its Subsidiaries in any
respect which if not cured would reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

Section 3.8 Ownership of Property Liens; Leases of Equipment.
Each of the Loan Parties has good and marketable title in fee simple (except
for exceptions to title as will not in the aggregate materially interfere with
the present or contemplated use of the property affected thereby) to, or a
valid leasehold interest in, all its real property, and good and marketable
title to all its other property, and none of such property is subject to any
Lien except Permitted Liens. None of the Equipment or Inventory (as defined in
any Security Agreement) owned by any Loan Party has been leased by such Loan
Party as lessor, except pursuant to operating leases (which do not constitute
Financing Leases) which are in one of the forms (with appropriate insertions as
to date, amounts, parties, and designation of Equipment or Inventory (as so
defined therein) covered thereby, and other minor deviations which do not
materially alter the terms thereof) attached hereto as part of Schedule II, as
the same may be modified from time to time as set forth in subsection 5.6(c).
Prior to the execution of this Agreement, Hanover Maintech has assigned all
leases of Equipment or Inventory owned by Hanover Maintech prior to the date of
this Agreement to the Borrower and, as of the date of this Agreement, Hanover
Maintech does not lease as lessor any Inventory or Equipment owned by Hanover
Maintech. None of the natural gas compressors and related equipment owned by
any Loan Party constitutes "fixtures" under the Uniform Commercial Code or
other applicable law of any jurisdiction in which such natural gas compressors
and related equipment are located. As used herein, Equipment or Inventory
leased by a Loan Party under a Financing Lease shall be deemed to be "owned" by
such Loan Party.

Section 3.9 Intellectual Property. Each Loan Party owns, or is
licensed to use, all trademarks, tradenames, trade secrets, copyrights,
technology, know-how, and processes necessary for the conduct of its business
as currently conducted (the "Intellectual Property") except for those the
failure to own or license which would not reasonably be expected to have a
Material Adverse Effect. To the knowledge of the Borrower, no claim has been
asserted and is pending by any Person challenging or questioning the use of any
such Intellectual Property or the validity or effectiveness of any such
Intellectual Property, nor does the Borrower know of any valid basis for any
such claim, which would reasonably be expected to have a Material Adverse
Effect. The use of such Intellectual Property by the Loan Parties does not
infringe on the rights of any Person,

-36-
43
except for such claims and infringements that, in the aggregate, would not
reasonably be expected to have a Material Adverse Effect.

Section 3.10 No Burdensome Restrictions. Except as set forth in
Schedule II, no Requirement of Law or Contractual Obligation of any Loan Party
would reasonably be expected to have a Material Adverse Effect.

Section 3.11 Taxes. Each of the Loan Parties has filed or caused
to be filed all tax returns which, to the knowledge of the Borrower, are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its property and all
other taxes, fees, or other charges imposed on it or any of its property by any
Governmental Authority (other than any 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 any of the Loan Parties, as the case may be), no tax Lien has been
filed against the property of any Loan Party, and, to the knowledge of the
Borrower, no claim is being asserted with respect to any such tax, fee, or
other charge which would reasonably be expected to have a Material Adverse
Effect.

Section 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 as now and
from time to time hereafter in effect or for any purpose which violates the
provisions of the Regulations of such Board of Governors. If requested by the
Agent, the Borrower will furnish to the Agent a statement to the foregoing
effect in conformity with the requirements of FR Form U-1 referred to in said
Regulation U.

Section 3.13 ERISA. Neither a Reportable Event nor an
"accumulated funding deficiency" (within the meaning of Section 412 of the Code
or Section 302 of ERISA) has occurred during the five-year period prior to the
date on which this representation is made or deemed made with respect to any
Plan, and each Plan has complied in all material respects with the applicable
provisions of ERISA and the Code. No termination of a Single Employer Plan has
occurred and no Lien in favor of the PBGC or a Plan has arisen during the
five-year period prior to the date as of which this representation is deemed
made. The present value of all accrued benefits under each Single Employer
Plan maintained by the Borrower or any Commonly Controlled Entity (based on
those assumptions used to fund the Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits. Neither the Borrower nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither the
Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization

-37-
44
or Insolvent. The present value (determined using actuarial and other
assumptions which are reasonable in respect of the benefits provided and the
employees participating) of the liability of the Borrower and each Commonly
Controlled Entity for post retirement benefits to be provided to their current
and former employees under Plans which are welfare benefit plans (as defined in
Section 3(1) of ERISA) does not, in the aggregate, exceed the assets under all
such Plans allocable to such benefits.

Section 3.14 Investment Company Act; Other Regulations. None of
the Loan Parties is an "investment company", or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended. None of the Loan Parties is subject to regulation under any
Federal or State statute or regulation which limits its ability to incur
Indebtedness or change rates or change tariffs. None of the Loan Parties are
"holding companies" or "subsidiary companies" of a "holding company" or a
"subsidiary company" of a "holding company" within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

Section 3.15 Subsidiaries. As of the date of this Agreement, the
Borrower has no Subsidiaries except as disclosed in Schedule II. Except as
disclosed in Schedule II, all shares of capital stock of each Subsidiary of the
Borrower have been duly and validly authorized and issued and are fully paid
and nonassessable and are owned by the Borrower free and clear of all Liens or
other encumbrances other than those in favor of the Collateral Trustee. There
are no outstanding subscriptions, warrants, options, calls, or commitments of
any character relating to or entitling any Person to purchase or otherwise
acquire from any Subsidiary of the Borrower any capital stock of such
Subsidiary of the Borrower. There are no obligations or securities convertible
into or exchangeable for any shares of capital stock of any Subsidiary of the
Borrower or any commitments of any character relating to or entitling any
Person to purchase or otherwise acquire any such obligations or securities.
There are no preemptive or similar rights to subscribe for or to purchase any
capital stock of any Subsidiary of the Borrower. Except as required in the
Pledge Agreements, no Subsidiary of the Borrower has entered into any agreement
to register its equity or debt securities under the Securities Act of 1933, as
amended.

Section 3.16 Purpose of Loans. The proceeds of the Loans shall be
used only for the general corporate purposes of the Borrower and its
Subsidiaries in the ordinary course of business, for the acquisition by the
Borrower and its Subsidiaries of natural gas compressors, oil and gas
production equipment, and related equipment, for Acquisitions, for the
repayment of the Indebtedness of the Borrower and its Subsidiaries existing
prior to the date of this Agreement, and for the reasonable fees, expenses, and
financing costs incurred by the Borrower in connection with the foregoing. The
proceeds of the Loans shall not be used for any purpose which violates
applicable Requirements of Law, including laws regulating investments in
foreign jurisdictions.

Section 3.17 Environmental Matters. Except as set forth in
Schedule II, each of the representations and warranties set forth in paragraphs
(a) through (h) of this Section is true and correct with respect to the
Borrower and its Subsidiaries and to each parcel of real property owned or
leased by the Borrower or any of its Subsidiaries currently or since 1990 (the
"Properties"), except as circumstances giving rise to any such failure to be so
true and correct would not reasonably be expected to have a Material Adverse
Effect:

(a) The Properties do not contain and have not
previously contained, therein, thereon, or thereunder, including,
without limitation, the soil and groundwater thereunder, any Hazardous
Materials in concentrations which violate Environmental Laws;

(b) The Properties, and all operations and
facilities at the Properties, possess all licenses, permits,
certificates, and registrations required by law and are in compliance
with all Environmental Laws;

(c) There is no Hazardous Materials contamination
or violation of any Environmental Law which could interfere with the
continued operation of any of the Properties or impair the fair
saleable value thereof;

(d) Neither the Borrower nor any of its
Subsidiaries has received any written complaint, or notice of
violation, alleged violation, investigation, advisory action,
potential liability, or potential responsibility, regarding
environmental protection matters or permit compliance with regard to
the Properties, nor is the Borrower aware that any Governmental
Authority or third party is contemplating delivering to the Borrower
or any of its Subsidiaries any such notice;

(e) Hazardous Materials have not been generated,
released, treated, stored, or disposed of at, on, or under any of the
Properties, nor have any Hazardous Materials been transferred from the
Properties to any other location;

(f) There are no governmental, administrative, or
judicial actions or proceedings pending under any Environmental Laws
to which the Borrower or any of its Subsidiaries is or will be named
as a party with respect to the Properties, nor are there any consent
decrees, other decrees, consent orders, administrative orders, or
other orders, or other administrative or judicial requirements,
outstanding under any Environmental Law with respect to any of the
Properties;

is being transferred, (ii) no such transfer on or before December 19, 1996,
shall cause JEDI to retain less than 50.1% of the aggregate outstanding
principal amount of the Loans, no such transfer shall cause JEDI to retain less
than 20% of the aggregate

-76-
83
outstanding principal amount of the Loans, no such transfer shall cause any
Lender that shall retain any portion of any Loan to retain less than 10% of
such Loan, and no such transfer shall cause the number of Lenders under this
Agreement to exceed ten Lenders, (iii) each such transfer shall be to an
Eligible Assignee, (iv) the parties to each such transfer shall execute and
deliver to the Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, and shall deliver to the Agent the existing Notes
subject to such transfer for reissuance, and (v) each transferee (other than
those of the Agent) shall pay to the Agent a $2,500 administrative fee.

(d) Notwithstanding any other rules regarding
transfers, JEDI may assign all of its Commitment to Enron Capital & Trade

such Persons are Eligible Assignees at the time of transfer, in the event that
JEDI dissolves pursuant to the terms of its organizational documents.

(e) Upon receipt of an Assignment and Acceptance
executed by a Lender and an Eligible Assignee, together with the Notes subject
to such assignment, if any, the Agent shall, if such Assignment and Acceptance
has been completed in the appropriate form, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register, and
(iii) give prompt notice thereof to the Borrower. If new Notes must be issued
in connection with the transfer, within five Business Days after the Borrower
receives notice of the transfer, the Borrower shall execute and deliver to the
Agent, in exchange for the surrendered old Notes subject to the transfer, new
Notes prepared by the Agent reflecting the transfer. Such new Notes shall be
dated the effective date of such Assignment and Acceptance and shall be in the
appropriate form and correctly reflect the effect of the transfer. Upon
execution, delivery, acceptance, and recording of the Assignment and
Acceptance, and as shown by the new Notes, if any, reflecting the transfer,
from and after the effective date specified in each Assignment and Acceptance:
(A) the transferee thereunder shall be a party hereto for all purposes and, to
the extent that rights and obligations hereunder have been transferred to the
transferee pursuant to such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder with respect to the Commitments or Advances
transferred to such Lender and (B) the transferor Lender thereunder shall, to
the extent that rights and obligations hereunder have been transferred by the
transferor Lender pursuant to such Assignment and Acceptance, relinquish the
transferor Lender's rights and be released from the transferor Lender's
obligations hereunder with respect to the Commitments and Advances transferred
by such Lender (and, in the case of an Assignment and Acceptance covering all
of such transferor Lender's Commitments and Advances under this Agreement, such
transferor Lender shall cease to be a party hereto).

(f) By executing and delivering an Assignment and
Acceptance, the transferor Lender thereunder and the transferee Lender
thereunder confirm to and agree with each other and the other parties hereto as
follows: (i) other than as provided in such Assignment and Acceptance, the
transferor Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties, or representations
made in or in

-77-
84
connection with this Agreement or the Loan Documents or the execution,
legality, validity, enforceability, genuineness, sufficiency, or value of this
Agreement, the Loan Documents, or any instrument or document furnished in
connection therewith; (ii) the transferor Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of any Loan Party or the performance or observance by any Loan Party of any of
their obligations under this Agreement, the Loan Documents, or any other
instrument or document furnished in connection therewith; (iii) such transferee

documents and information as such transferee has deemed appropriate to make
such transferee's own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such transferee Lender shall, independently and
without reliance upon the Agent, the transferor Lender, or any other Lender and
based on such documents and information as such transferee shall deem
appropriate at the time, continue to make such transferee's own credit
decisions in taking or not taking action under this Agreement and the Loan
Documents; (v) such transferee Lender appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers under this
Agreement as are specified for the Agent under the terms of this Agreement and
the Loan Documents; and (vi) such transferee Lender agrees that it shall
perform as a Lender under the Loan Documents.

(g) The Agent shall maintain a copy of this
Agreement and of each Assignment and Acceptance delivered to and accepted by
the Agent, together with a register specifying the names and addresses of the
Lenders under this Agreement, the percentage of the Commitments hereunder held
by each Lender, and the percentage of each Loan hereunder held by each Lender
(the "Register"). The entries in the Register shall be conclusive and binding
for all purposes, absent manifest error, and the Borrower, the Agent, and the
Lenders may treat each Person whose name is recorded in the Register as a
Lender hereunder for all purposes of this 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.

(h) Each Lender may sell participations to one or
more banks or other entities in or to all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment and the Advances owing to it); provided, however,
that (i) such Lender's obligations under this Agreement (including, without
limitation, its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto
for the performance of such obligations, (iii) such Lender shall remain the
holder of its Notes for all purposes of this Agreement, (iv) the Borrower, the
Agent, and the other Lenders shall continue to deal solely and directly with
such Lender in connection with such Lender's rights and obligations under this
Agreement, and (v) such Lender shall not require the participant's consent to
any matter under this Agreement, except for change in the matters expressed in
Section 9.2(b) or (c). Each Lender which sells any participation hereunder
agrees to provide the Borrower and the Agent with notice of any such actions,
but the

-78-
85
failure to provide such notice shall not invalidate such actions. In the event
that any Lender sells any participation hereunder, the participants shall have
rights under Sections 2.8, 2.9, 2.10, 2.11, 2.12, 6.2(c), and 9.3 with respect
to their participation interest to the same extent as the selling Lender.

Section 9.7 Renewal, Extension, or Rearrangement. All provisions
of this Agreement and of any other Loan Documents relating to the Loan
Obligations shall apply with equal force and effect to each and all promissory
notes and other documents hereinafter executed which in whole or in part
represent a renewal, extension, increase, or rearrangement of any part of the
Loan Obligations.

Section 9.8 No Implied Waiver. No course of dealing on the part
of the Agent or any Lender or their respective Related Parties, nor any failure
or delay with respect to exercising any right, power, or privilege of the Agent
or any Lender under this Agreement or any other Loan Document shall operate as
a waiver thereof.

Section 9.9 Cumulative Rights. Rights and remedies of the Agent
and the Lenders under this Agreement and each other Loan Document shall be
cumulative, and the exercise or partial exercise of any such right or remedy
shall not preclude the exercise of any other right or remedy.

Section 9.10 Interpretation. Words used herein in the singular,
where the context so permits, shall be deemed to include the plural and vice
versa. The definitions of words in the singular herein shall apply to such
words when used in the plural where the context so permits and vice versa. The
word "including" shall mean "including but not limited to." The word "or"
shall mean "and/or" wherever necessary to prevent interpretation of any
provision against the Agent or the Lenders. Whenever the Borrower has an
obligation under this Agreement and the Loan Documents the expense of complying
with that obligation shall be an expense of the Borrower unless otherwise
specified.

OTHERWISE SPECIFIED IN ANOTHER LOAN DOCUMENT, THIS AGREEMENT, THE NOTES, AND
THE LOAN DOCUMENTS, AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES IN CONNECTION

PRINCIPLES OF THE STATE OF NEW YORK.

-79-
86
(A) SUBMITS FOR ITSELF AND ITS PROPERTY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS TO WHICH IT IS A PARTY, OR FOR RECOGNITION AND ENFORCEMENT
OF ANY JUDGEMENT IN RESPECT THEREOF, TO THE NON-EXCLUSIVE GENERAL
JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK, THE COURTS OF THE
UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND
APPELLATE COURTS FROM ANY THEREOF;

(B) CONSENTS THAT ANY SUCH ACTION OR PROCEEDING MAY BE
BROUGHT IN SUCH COURTS AND WAIVES ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE 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 SUCH PERSON AT ITS ADDRESS SET FORTH IN SECTION 9.1 OR AT
SUCH OTHER ADDRESS OF WHICH THE AGENT SHALL HAVE BEEN NOTIFIED
PURSUANT THERETO;

(D) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO

(E) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW,
ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LEGAL ACTION OR

SECTION 9.13 WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENT,
AND EACH LENDER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN
ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT, THE NOTES, OR ANY
OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

Section 9.14 Prevention of Usury. It is the intention of the
parties hereto to conform strictly to usury laws applicable to this
transaction. Accordingly, if the transactions contemplated hereby would be
usurious under applicable law, then, in that event, notwithstanding anything to

-80-
87
the contrary in this Agreement or in any other Loan Document, it is agreed as
follows: (a) the aggregate of all consideration which constitutes interest
under law applicable to the Lenders that is contracted for, taken, reserved,
charged, or received under this Agreement and the Loan Documents or agreements
or otherwise in connection with this transaction shall under no circumstances
exceed the maximum amount allowed by such applicable law, and any excess shall
be cancelled automatically and if previously paid shall be credited by the
applicable Lender on the principal amount of the Loan Obligations owed to such
Lender (or, to the extent that the principal amount of the Loan Obligations
owed to such Lender shall have been or would thereby be paid in full, refunded
to the Borrower); and (b) in the event that the maturity of the Loan
Obligations is accelerated by reason of an election of the Agent or the Lenders
resulting from any Event of Default under this Agreement or otherwise, or in
the event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to this transaction may never include
more than the maximum amount allowed by such applicable law, and excess
interest, if any, provided for in this Agreement or otherwise in connection
with the Loans shall be cancelled automatically and, if theretofore paid, shall
be credited by the applicable Lender on the principal amount of the Loan
Obligations owed to such Lender (or, to the extent that the principal amount of
the Loan Obligations owed to such Lender shall have been or would thereby be
paid in full, refunded to the Borrower). The right to accelerate the maturity
of the Loan Obligations does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and no Lender
intends to collect any unearned interest in the event of acceleration. All
sums paid or agreed to be paid to each Lender for the use, forbearance, or
detention of sums included in the Loan Obligations owed to such Lender shall,
to the extent permitted by applicable law, be amortized, prorated, allocated,
and spread throughout the full term of this Agreement until payment in full so
that the rate or amount of interest on account of the Loan Obligations owed to
such Lender does not exceed the applicable usury ceiling, if any. As used in
this Section 9.14, the term "applicable law" shall mean the laws which govern
this Agreement as described in Section 9.11 (or the law of any other
jurisdiction whose laws may be mandatorily applicable notwithstanding other
provisions of this Agreement), or law of the United States of America
applicable to the applicable Lender and the Loans which would permit such
Lender to contract for, charge, take, reserve, or receive a greater amount of
interest than under any other applicable law.

Section 9.15 References. The words "herein," "hereof,"
"hereunder" and other words of similar import when used in this Agreement refer
to this Agreement as a whole, and not to any particular article, section, or
subsection. Any reference herein to a Section or Subsection shall be deemed to
refer to the applicable Section or Subsection of this Agreement unless
otherwise stated herein. Any reference herein to an exhibit shall be deemed to
refer to the applicable exhibit attached hereto unless otherwise stated herein.
Any reference herein to any instrument, document, or other agreement shall be
deemed to refer to such instrument, document, or agreement as the same may be
amended, supplemented, and otherwise modified from time to time, unless
expressly stated otherwise.

-81-
88
Section 9.16 Governmental Regulation. Anything contained
in this Agreement to the contrary notwithstanding, no Lender shall be obligated
to extend credit to the Borrower in an amount in violation of any limitation or
prohibition provided by any applicable statute or regulation.

SECTION 9.17 ENTIRE AGREEMENT. THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING AMONG THE
AGENT, THE LENDERS, AND THE BORROWER AND SUPERSEDE ALL OTHER AGREEMENTS AND
UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT MATTER THEREOF.
THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

Section 9.19 Titles of Articles, Sections, and Subsections.
All titles or headings to articles, sections, subsections, or other divisions

parties and shall not be construed to have any effect or meaning with respect
to the other content of such articles, sections, subsections, or other
divisions, such other content being controlling as to the agreement between the
parties hereto.

Section 9.20 Satisfaction Requirement. If any agreement,
certificate, instrument, or other writing, or any action taken or to be taken,
is by the terms of this Agreement required to be satisfactory to any party, the
determination of such satisfaction shall be made by such party in its sole and
exclusive judgment unless another standard (e.g. "reasonably satisfactory") is
expressly provided for in connection with such matter. Whenever any
determination is to be made by any party, including those determinations by the
Agent or the Lenders under Sections 2.1, 2.2, 2.3, 2.4, 7.1, 7.2, and 7.3, such
determination shall be in such party's sole and exclusive judgment unless
another standard (e.g. "reasonable determination") is expressly provided for in
connection with such matter.

Section 9.21 Counterparts. This Agreement may be executed
in two or more counterparts, and it shall not be necessary that the signatures
of all parties hereto be contained on any one counterpart hereof; each
counterpart shall be deemed an original, but all of which together shall
constitute one and the same instrument.
