ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.


         On November 30, 1994, Tidewater Inc. completed its acquisition of the
natural gas compression assets (the "Assets") of Halliburton Company and
Halliburton Canada Inc. (hereinafter collectively referred to as
"Halliburton").  The Assets were acquired by Tidewater Inc.'s wholly-owned
subsidiary, Tidewater Compression Service, Inc. (hereinafter together with
Tidewater Inc. collectively referred to as the "Company").  The purchase price
paid by the Company was approximately $205 million which is subject to
adjustment based on a final balance sheet prepared as of the closing date.
Consideration for the acquisition was arrived at by arms-length negotiations
between the Company and Halliburton.

         The terms and conditions of the acquisition are set forth in full in
the Purchase and Sale Agreement dated October 18, 1994 by and between the
Company and Halliburton, which was filed as Exhibit 10 to Tidewater Inc.'s
Report on Form 10-Q for the quarterly period ended September 30, 1994 and is
incorporated herein by reference.

         The tangible assets acquired as a result of the merger primarily
consisted of 1,545 natural gas compressor units with a combined horsepower of
approximately 235,300.  Prior to the closing date of the acquisition, the
compressors were principally used by Halliburton to provide natural gas
compression services to customers in the production of oil and gas.  The
existing agreements entered into by Halliburton for the rental of these
compressors have been assumed by the Company who will carry out their terms.
The Company intends to continue to devote the use of the compressors to the
purpose for which they had been used prior to the closing date of the
acquisition.

         With the completion of the acquisition of the Halliburton Assets, the
Company will own and operate approximately 2,900 natural gas compressors with a
combined horsepower of approximately 480,000.  The Company believes that the
acquisition provides an opportunity to realize significant and substantial
growth due to the size of the Halliburton fleet, the type of equipment, the
existing customer profile, and the geographic distribution of operations.

         The source of the funds used for the acquisition consisted of working
capital and borrowing of $150 million under a Revolving Credit and Term Loan
Agreement among Tidewater Inc. and certain of its domestic subsidiaries, as
borrowers, and First National Bank of Commerce, The First National Bank of 
Boston, Texas Commerce Bank National Association, AmSouth Bank of Alabama,
Whitney National Bank, Hibernia National Bank, and Premier Bank National 
Association, as lenders.

         There is no material relationship between Halliburton, its affiliates,
directors or officers and the Company, its affiliates, directors or officers.
After the closing of the acquisition, certain employees of the Compression
Services Division of Halliburton were offered and accepted employment by the
Company.

$130,000,000 through September 30, 1995, after which the line of credit
converts to a four-year term loan.

         B.      The Companies wish (i) to extend the maturity date of the line
of credit to September 30, 1996, after which the line of credit converts to a
four-year term loan, and (ii) obtain a new term loan to Compression in the
aggregate principal amount of $120,000,000.  In order to do so, the Agents have
arranged for the existing Lenders to increase the amount of their respective
commitments.  The Companies and the Lenders wish to provide for the foregoing
pursuant to this amendment and restatement of the Existing Loan Agreement.


                                   AGREEMENT

         NOW, THEREFORE, for and in consideration of the mutual covenants,
agreements and undertakings herein contained, Lenders

         1.1     Credit Facility.  The Lenders shall establish a revolving line
of credit (the "Line of Credit") which may be drawn upon by the Companies on
any Business Day during the period from the date hereof until and including
September 30, 1996, in such amounts (but not less than $5,000,000 per Credit
Facility Advance and above $5,000,000 in even multiples of $1,000,000) as the
Companies may from time to time request (individually, a "Credit Facility
Advance" and, collectively, the "Credit Facility Advances"), but not exceeding
the Line of Credit Commitments (the "Credit Facility"), which amount
outstanding under said Line of Credit as of the close of business on September
30, 1996, shall then convert on the following day to a four (4) year term loan
(the "Working Capital Term Loan") with principal payable quarterly on a four
(4) year amortization schedule.  The Credit available to the Companies from
time to time under the Line of Credit within the Credit





                                    -  2  -
<PAGE>   7
Facility shall be reduced by the aggregate of the face amount of any and all
unpaid Credit Facility Advances made by the Lenders to the Companies pursuant
to this Agreement and shall constitute the "Unused Credit Facility Credit."
Irrespective of the Company or Companies who directly or indirectly receive the
amounts funded on Credit Facility Advances, each of the Companies shall be
liable jointly and severally and solidarily to the Lenders for all amounts
outstanding from time to time under the Credit Facility.

         1.2     Borrowing Procedure Under the Credit Facility.  Credit
Facility Advances shall be made as follows:  (i) in the case of a Prime Rate
Advance, on notice from the Company to the Administrative Agent received by the
Administrative Agent no later than 10:00 A.M. (Central time) on the date of
such proposed Credit Facility Advance, specifying the amount thereof; and (ii)
in the case of a LIBO Rate Advance, on notice from the Company to the
Administrative Agent at least three (3) Business Days prior to the date of such
proposed Credit Facility Advance.  The Administrative Agent will use its best
efforts to give telephone notice of a proposed Credit Facility Advance on the
same day such notice is received by the Administrative Agent from the Company.
Not later than 2:00 P.M. (Central time) on the date of such Credit Facility
Advance and upon fulfillment of the applicable conditions set forth in Section
7, the Lenders will make such Credit Facility Advance available to the
Administrative Agent, which shall make such total Credit Facility Advance
available to the Company in same day funds at the Administrative Agent's office
at 210 Baronne Street, New Orleans, Louisiana.  The request for a Credit
Facility Advance shall constitute a certification by the Companies that all of
the representations and warranties contained in Section 5 are true and correct
as of the date of such request.  Subject to the provisions of Section 9.2
hereof, the Lenders shall be obligated to fund Credit Facility Advances in
proportion to their Commitments.  The obligations of the Lenders under this
Agreement shall be separate and several and not joint and several or solidary;
none of the Lenders shall be responsible or liable for the acts or omissions of
any of the other Lenders.

         1.3     Compression Term Loan.  The Lenders shall make a seven (7)
year term loan to Compression (the "Compression Term Loan") in an amount not to
exceed the Compression Term Loan Commitments with principal payable quarterly.
Inasmuch as Compression will receive all of the amounts funded on the
Compression Term Loan, each of the other Companies hereby irrevocably
guarantees, jointly and severally and solidarily with Compression and with each
of the other Companies, all amounts outstanding from time to time under the
Compression Term Loan.  Each of the Companies (other than Compression) hereby
agrees that its guaranty obligations hereunder shall be absolute and
unconditional and shall be unaffected by any failure to enforce the provisions
of this Agreement or any of the





                                    -  3  -
<PAGE>   8
Compression Term Notes, any waiver, modification or indulgence granted by the
Lenders to the Company with respect thereto, or any other circumstances which
might otherwise constitute a legal or equitable discharge of a surety or
guarantor.  The Companies (other than Compression) hereby waive diligence,
presentment, filing of claims with the Court in the event of a merger or
bankruptcy of Compression, any right to require proceeding first against
Compression, the benefit of discussion, protest or notice with respect to the
indebtedness under the Compression Term Notes and all demands whatsoever.  The
Companies (other than Compression) further agree that they shall not be
entitled to, and hereby irrevocably waive, any right of subrogation in relation
to the Lenders for so long as any portion of the Compression Term Loan remains
unpaid.

         1.4     Use of Proceeds.  The Companies shall use the proceeds of the
Credit Facility and Working Capital Term Loan only for general corporate
purposes not inconsistent with the provisions of this Agreement, including the
acquisition of the gas compression division of Halliburton Company.
Compression shall use the proceeds of the Compression Term Loan only for the
acquisition of the gas compression division of Halliburton Company.


         Section 2.  Promissory Notes; Guaranty.

         2.1     Line of Credit Notes.  The Credit Facility shall be evidenced
by promissory notes of the Companies, each in the form of Exhibit "B" to this
Agreement, dated the date of this Agreement, and payable to each Lender
respectively (together with any and all renewals, extensions, rearrangements
and/or modifications thereof, the "Line of Credit Notes"), in the amount of the
Lenders' respective maximum Line of Credit Commitments, with appropriate
insertions, and payable in full on September 30, 1996.

         2.2     Working Capital Term Notes.  The Working Capital Term Loan
shall be evidenced by promissory notes of the Companies in the form of Exhibit
"C" to this Agreement, dated October 1, 1996, payable to the order of each
Lender respectively (together with any and all renewals, extensions,
rearrangements and/or modifications thereof, the "Working Capital Term Notes"),
in the Lenders' respective proportionate amount of the Working Capital Term
Loan, with appropriate insertions, and payable in full on September 30, 2000.
The Working Capital Term Notes shall provide for payment of quarterly
installments of principal in an amount equal to one-sixteenth (1/16th) of the
initial principal balance thereof.  Once the Working Capital Term Loan is
initially funded, the Lenders shall not fund any additional Credit Facility
Advances under the Working Capital Term Loan.

         2.3     Compression Term Notes.  The Compression Term Loan shall be
evidenced by promissory notes of Compression in the form of Exhibit "D" to this
Agreement, dated the date on which the Compression Term Loan is funded, payable

Notes"), in the Lenders' respective Compression Term Loan Commitments.  The
Compression Term Notes shall provide for payment of quarterly installments of
principal in the aggregate amount of $3,000,000 for the first twenty-seven (27)
quarters after the date of the Compression Term Notes, with the balance of all
principal due at maturity on the last day of the twenty-eighth (28th) quarter
after the date of the Compression Term Notes.

continue as to said Tranche until changed in accordance with the following.
The Company shall notify the Administrative Agent of the Company's desire to
change the interest rate on Credit Facility Advances (or any portion thereof)
not less than three (3) Business Days prior to the date on which such change
shall be effective.  The Company may change from Prime Rate Advances to  LIBO
Rate Advances at any time without payment of premium or penalty, but the
Company may change from LIBO Rate Advances to Prime Rate Advances only as of
the last day of a LIBOR Interest Period without payment of premium or penalty.
In the absence of any specific rate election by the Company, the Line of Credit
Notes shall bear interest at the Prime Rate plus three-eighths of one percent
(0.375%).  Not more than twelve (12) Line of Credit LIBO Rate Tranches shall be

         3.4     Interest - Administrative Agent's Determination.  (a) The
Administrative Agent shall determine the amount of interest payable on each
Tranche, and its determination shall be conclusive in the absence of manifest
error.  The Administrative Agent shall endeavor to notify the Company of the
amount of any interest payment prior to the date on which an interest payment
is due: provided that the failure of the Administrative Agent to provide such
notice shall not affect the Companies' obligation to pay interest on such date.

         (b)     If the Administrative Agent gives notice to the Company that
no LIBO Rate is quoted to the Administrative Agent for the applicable LIBOR
Interest Period or in the applicable amounts, then (i) the obligation of the
Lenders to make a LIBO Rate Advance and the ability of the Company to select
the LIBO Rate for a Tranche shall be suspended, and (ii) the Companies shall
either prepay all LIBO Rate Tranches for which an interest rate is to be
determined on such date or the Notes shall thereafter bear interest at the
Prime Rate plus three-eighths of one percent (0.375%).

         (c)     If any applicable domestic or foreign law, treaty, rule or
regulation (whether now in effect or hereinafter enacted or promulgated,
including Regulation D of the Board of Governors of the Federal Reserve System)
or any interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof (whether or not
having the force of law):

                 (i)  changes the basis of taxation of payments to the Lenders
         of any principal, interest, or other amounts attributable to any LIBO
         Rate Tranche (other than taxes imposed on the overall net income of
         the Lenders or any lending office of the Lenders by any jurisdiction
         in which the Lenders or any such lending office is located);

                 (ii)  changes, imposes, modifies, applies or deems applicable
         any reserve, special deposit, insurance assessments or similar
         requirements in respect of any such LIBO Rate Tranche (excluding those
         for which the Lenders are fully compensated pursuant to adjustments
         made in the definition of LIBO Rate) or against assets





                                    -  7  -
<PAGE>   12
         of, deposits with or for the account of, or credit extended by, the 
         Lenders; or

                 (iii)  imposes on the Lenders or the interbank eurocurrency
         deposit and transfer market any other condition affecting any such
         LIBO Rate Tranche,

and the result of any of the foregoing is to increase the cost to the Lenders
of funding or maintaining any such LIBO Rate Tranche (other than costs for
which the Lenders are fully compensated pursuant to adjustments made in the
definition of LIBO Rate) or to reduce the amount of any sum receivable by the
Lenders in respect of any such LIBO Rate Tranche by an amount deemed by the
Lenders to be material, then the Administrative Agent shall promptly notify the
Companies in writing (such writing including the necessary calculations in
reasonable detail) of the happening of such event and the Companies shall upon
demand pay to the Lenders such additional amount or amounts as will compensate
the Lenders for such additional cost or reduction accrued as of the time of
such notice and thereafter, the Companies may either continue to pay to the
Lenders such additional amount as will compensate the Lenders for the
additional cost or reduction of LIBO Rate Tranches, or the Companies may elect,
by giving to the Administrative Agent not less than three Business Days'
notice, to change the interest rate applicable to such Tranche from the LIBO
Rate to the Prime Rate plus three-eighths of one percent (0.375%).

         (d)     Notwithstanding any other provision hereof, if any change in
applicable laws, treaties, rules or regulations or in the interpretation or
administration thereof of or in any jurisdiction whatsoever, domestic or
foreign, shall make it unlawful or impracticable for the Lenders to maintain
LIBO Rate Tranches bearing interest at the LIBO Rate, or shall materially
restrict the authority of the Lenders to purchase, sell or take certificates of
deposit or offshore deposits of dollars, then all LIBO Rate Tranches which are
then outstanding and which cannot lawfully or practicably be maintained shall
immediately cease to bear interest at the LIBO Rate and shall commence to bear
interest at the Prime Rate plus three-eighths of one percent (0.375%).  The
Companies agree to indemnify the Lenders and hold them harmless against all
costs, expenses, claims, penalties, liabilities and damages which may result
from any such change in law, treaty, rule, regulation, interpretation or
administration, arising out of or in connection with this Agreement and the
Loans.

         (e)     The Companies will indemnify the Lenders against, and
reimburse each Lender on demand for, any loss or expense incurred or sustained
by the Lenders (including without limitation, any loss or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired
by the Lenders to fund or maintain





                                    -  8  -
<PAGE>   13
LIBO Rate Tranches) as a result of (i) any payment or prepayment (whether
authorized or required hereunder or otherwise) of all or a portion of any such
Tranche on a day other than the day on which the applicable LIBOR Interest
Period ends, (ii) any payment or prepayment, whether required hereunder or
otherwise, of LIBO Rate Tranches made after the delivery, but before the
effective date, of an election to have the LIBO Rate apply to a LIBO Rate
Tranche, if such payment or prepayment prevents such election from becoming
fully effective, or (iii) the failure of any LIBO Rate Tranche to be made by
the Lenders or of any such election to become effective due to any condition
precedent to a LIBO Rate Tranche not being satisfied or due to any other action
or inaction of the Companies.  For purposes of this Subsection, funding losses
arising by reason of liquidation or reemployment of deposits or other funds
acquired by the Lenders to fund or maintain LIBO Rate Tranches shall be
calculated as (A) the remainder, if a positive number, obtained by subtracting
(1) the yield (reflecting both stated interest rate and discount, if any) to
maturity of obligations of the United States Treasury as determined by the
Administrative Agent in an amount equal or comparable to such advance for the
period of time commencing on the date of the payment, prepayment or change of
rate as provided above and ending on the last day of the subject LIBOR Interest
Period, from (2) the LIBO Rate of the subject LIBOR Interest Period, (B) times
the number of days from the date of payment, prepayment or change of rate to
the last day of the LIBOR Interest Period, divided by 360, (C) times the amount
of the applicable LIBO Rate Tranche.  Any payment due under this section will
be paid to the Administrative Agent within five days after the Administrative
Agent delivers to the Company a certificate setting forth in reasonable detail
the amount of such payment, which certificate shall be conclusive in the
absence of manifest error.

         (f)     The Companies covenant and agree that:

                 (i)  The Companies will pay, when due and on an after-tax
         basis, all present and future income, stamp and other taxes, levies,
         costs and charges whatsoever imposed, assessed, levied or collected on
         or in respect of any LIBO Rate Tranche (other than taxes, levies,
         costs or charges imposed on or measured by the overall net income of
         the Lenders, or any lending office of the Lenders by any jurisdiction
         in which the Lenders or any such lending office is located) (all such
         non-excluded taxes, levies, costs and charges being collectively
         called "Reimbursable Taxes").  Promptly after the date on which
         payment of any Reimbursable Taxes is due pursuant to applicable law,
         the Companies will, at the request of the Administrative Agent,
         furnish to the Lenders evidence in form and substance satisfactory to
         the Lenders that





                                    -  9  -
<PAGE>   14
         the Companies have met their obligation under this subsection.

                 (ii)  The Companies will indemnify the Administrative Agent
         and the Lenders against, and reimburse the Administrative Agent and
         the Lenders on demand for, any Reimbursable Taxes paid by the
         Administrative Agent and the Lenders and any loss, liability, claim or
         expense, including interest, penalties and legal fees, that the
         Administrative Agent and the Lenders may incur at any time arising out
         of or in connection with the failure of the Companies to make any
         payment of Reimbursable Taxes when due.  Any payment due under this
         subsection will be paid to the Administrative Agent within five days
         after demand therefor by the Administrative Agent.

                 (iii)  All payments on account of the principal of, and
         interest on, LIBO Rate Tranches and all other amounts payable by the
         Companies to the Lenders hereunder shall be made free and clear of and
         without reduction by reason of any Reimbursable Taxes.

                 (iv)  If the Companies are ever required to pay any
         Reimbursable Taxes with respect to any LIBO Rate Tranches, the
         Companies may elect, by giving to the Administrative Agent not less
         than three (3) Business Days' notice, to change the interest rate
         applicable to any such advance from the LIBO Rate to the Prime Rate
         plus three-eighths of one percent (0.375%), but such election shall
         not diminish the Companies' obligation to pay all Reimbursable Taxes
         theretofore imposed, assessed, levied or collected.

         (g)     If any applicable law or regulation, or the action of any
applicable regulatory requirement increases the reserves or  capital required
for the Credit, the Administrative Agent shall promptly deliver a certificate
to the Company specifying in reasonable detail the additional amount as will
compensate the Lenders for the additional costs, which certificate shall be
conclusive in the absence of manifest error.  The Companies shall pay the
amount specified in such certificate promptly upon receipt.

         3.5     Payment Dates; Late Payment.  Interest on Prime Rate Advances
under any of the Loans shall be payable quarterly in arrears on the last day of

1995; the balance of all outstanding principal and accrued but unpaid interest
shall be payable at maturity on December 31, 2001.  Principal payments under
each respective Loan shall be allocated first to Prime Rate Tranches, then to
LIBO Rate Tranches having a LIBOR Interest Period ending on the quarterly
installment payment date, and then to LIBO Rate Tranches having a LIBOR
Interest Period ending subsequent to the quarterly installment payment date (in

Facility Credit for that quarter.

         (c)     An Agents' fee for the Credit Facility and Compression Term
Loan of $75,000 per year shall be payable by the Companies to the Agents (which
shall be shared equally and retained by the Agents) in advance on the date of
this Agreement and each succeeding anniversary date hereof until the Loans are
paid in full and this Agreement is terminated.  If the Compression Term Loan is
repaid in full, the annual Agents' fee shall thereafter be $40,000 per year
beginning on the anniversary date of this Agreement next occurring after the
date of such repayment in full.

         3.7     Method of Calculating Interest and Fees.  Interest and the
facility fee shall be computed on the basis of a year consisting of 360 days
and a month consisting of 30 days and paid for actual days elapsed.


         Section 4.  Payments, Reduction or Termination of the Credit and
Prepayments.

         4.1     Place of Payment.  All payments hereunder (including payments
of interest, principal and fees with respect to the Line of Credit Notes and
the Term Notes) shall be made by the Companies to the Administrative Agent in
immediately available funds, prior to 1:00 p.m. (Central time) at its offices
at 210 Baronne Street, New Orleans, Louisiana  70112, or at such other place as
may be designated by Administrative Agent to the Companies in writing.  Any
payment received after 1:00 p.m. (Central time) shall be deemed received on the
next Business Day.  Whenever any payment to be made hereunder or under the Line
of Credit Notes or the Term Notes fall on a date other than a Business Day,
such payment may be made on the next succeeding Business Day, and such
extension of time shall be included in the computation of payment of interest
or any fees.

         4.2     Reduction of Credit under the Line of Credit; Prepayments.
(a) The Companies may from time to time (in the case of Prime Rate Tranches) or
at the end of any LIBOR Interest Period (in the case of LIBO Rate Tranches),
upon at least three (3) Business Days's prior telephonic notice (confirmed in
writing) to Administrative Agent, permanently reduce the amount of the
Commitments available under the Line of Credit (which Commitments shall be
reduced proportionately by the Lenders), but only upon payment of the
outstanding principal amount of the Line of Credit Notes in excess of the then
reduced amount of the Commitments available under the Line of Credit.  Any such
reduction shall be in an amount of $10,000,000.00 or an integral multiple
thereof.  The Companies may at any time (in the case of Prime Rate Tranches) or
at the end of any LIBOR Interest Period (in the case of LIBO Rate Tranches), on
like notice, terminate the Commitments available under the Line of Credit upon
payment in full of the Line of Credit Notes and other liabilities of the
Companies hereunder (excluding





                                    -  12  -
<PAGE>   17
the Compression Term Loan).  In the case of either a reduction or termination
of the Commitments, the Companies shall thereafter have no right to increase or
restore the Commitments.

         (b)     The Companies may from time to time (in the case of Prime Rate
Tranches) or at the end of any LIBOR Interest Period (in the case of LIBO Rate
Tranches) prepay the principal of the  Line of Credit Notes in whole or in part
without premium; provided, however, any partial prepayment of principal shall
be in an amount of $1,000,000.00 or any integral multiple thereof.  Any
prepayment of the principal of the Line of Credit Note shall include accrued
interest to the date of prepayment on the principal amount being prepaid.

         4.3     Prepayments of Term Notes.  The Companies may from time to
time (in the case of Prime Rate Tranches) or at the end of any LIBOR Interest
Period (in the case of LIBO Rate Tranches), upon at least one Business Day's
prior telephonic notice (confirmed in writing) to the Administrative Agent,
prepay the principal of the Term Notes in whole or in part without premium;
provided, however, any partial prepayment of principal shall be in an amount of
$1,000,000.00 or an integral multiple thereof.  Any prepayment of the principal
of the Term Notes shall include accrued interest to the date of prepayment on
the principal amount being prepaid.  All prepayments when made shall be applied
to unpaid installments of principal in the inverse order of maturity.  All
prepayments shall be in addition to and not in lieu of, and shall not relieve
the Companies from the obligation to pay, scheduled installments of principal
in accordance with the Term Notes.

         4.4     Pro Rata Payments.  All payments and prepayments of principal,
interest, fees (except the Agents' fee described in Section 3.6(c) hereof) and
other amounts paid by the Companies to the Administrative Agent from time to
time under this Agreement shall be promptly wired by the Administrative Agent
to the Lenders in proportion to their Commitments.


         Section 5.  Representations and Warranties of the Companies.

         The Companies represent and warrant to the Lenders that:

         5.1     Corporate Existence.  Each of the Companies is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction in which it is incorporated and is duly qualified and in good
standing in all jurisdictions wherein the property it owns or the business it
transacts make such qualification necessary as a foreign corporation, except
where the failure to so qualify would not materially impair the ability of the
Company or any of its Subsidiaries to operate its business or





                                    -  13  -
<PAGE>   18
own its assets; and each of the Companies has and will continue to have all
necessary corporate power and authority to acquire, own and hold the property
and all other properties it purports to own and hold and to carry on  its
business as now conducted.  The Domestic Subsidiaries listed on Exhibit "A"
attached hereto constitute all of the Domestic Subsidiaries of the Company.

         5.2     Authorization; Validity.  Each of the Companies is and/or has
been duly authorized to execute and deliver this Agreement, the Line of Credit
Notes and the Term Notes and is and will continue to be duly authorized to
borrow monies hereunder and to perform its obligations under this Agreement,
the Line of Credit Notes and the Term Notes, as the case may be.  This
Agreement, the Line of Credit Notes and the Term Notes, as executed and when
delivered, shall constitute the legal, valid and binding obligations of each of
the Companies, enforceable in accordance with their respective terms.

         5.3     Conflicting Agreements and Other Matters.  Neither the Company
nor any of its Subsidiaries is a party to any contract or agreement or subject
to any charter or other corporate restriction which materially and adversely
affects the business, property, assets, or financial condition of the Company
and its Subsidiaries, taken as a whole.  Neither the execution nor delivery of
this Agreement or the Notes, nor fulfillment of nor compliance with the terms
and provisions hereof and of the Notes will conflict with, or result in a
breach of the terms, conditions or provisions of, or constitute a default
under, the charter or by-laws of the Company or any of its Subsidiaries, any
award of any arbitrator or any agreement (including any agreement with
stockholders) or instrument to which the Company or any of its Subsidiaries is
now a party, or result in the creation of any Lien on any property or assets of
the Company or any of its Subsidiaries, or constitute a violation of any law,
statute, rule, regulation, order, judgment or decree to which the Company or
any of its Subsidiaries is subject.  Neither the Company nor any of its
Subsidiaries is a party to, or otherwise subject to any provision contained in,
any instrument evidencing indebtedness of the Company or such Subsidiary, any
agreement relating thereto or any other contract or agreement (including its
charter) which (i) limits the amount of, or otherwise imposes restrictions on
the incurring of, Debt of the Companies of the type to be evidenced by the
Credit, or (ii) which imposes restrictions on the granting of Liens by the
Companies on otherwise unencumbered assets of the Companies as security for the
Credit.

         5.4     Financial Statements.  The Company has furnished the Lenders
with the consolidated balance sheets of the Company and its Subsidiaries as at
fiscal year end in each of the years 1992 through 1994, inclusive, and for the
six-month period ending September 30, 1994 and a consolidated statement of
income and statement of cash flows for each such fiscal year and such six-





                                    -  14  -
<PAGE>   19
month period, all identified by a principal financial officer of such Company
and all (other than any financial information for such six-month period)
certified by KPMG Peat Marwick LLP (or its predecessor).  Such financial
statements (including any related schedules and/or notes) are true and correct
in all material respects (subject, as to interim statements, to changes
resulting from audits and normal year-end adjustments) and have been prepared
in accordance with generally accepted accounting principles, and, unless
otherwise set forth therein, consistently followed throughout the periods
involved and show all liabilities, direct and contingent, of the Company and
its Subsidiaries required to be shown in accordance with such principles.  The
balance sheets fairly present the condition of the Company and its Subsidiaries
as at the dates thereof, and the related statements of earnings, stockholders'
equity and cash flows fairly present the results of the operations of the
Company and its Subsidiaries for the periods indicated.  There has been no
material adverse change in the business, condition or operations (financial or
otherwise) of the Company and its Subsidiaries taken as a whole, since
September 30, 1994.

         5.5     Litigation and Contingent Liabilities.  No litigation or
governmental proceedings are pending or threatened against the Company or any
of its Subsidiaries, the results of which are likely to materially adversely
affect the financial condition or operations of the Company and its
Subsidiaries on a consolidated basis, except as provided for or disclosed in
the financial statements referred to in Section 5.4 hereof.  Other than any
liability incident to such litigation or proceedings provided for or disclosed
in the financial statements referred to in Section 5.4 hereof, or any other
material contingent liabilities provided for or disclosed in the financial
statements referred to in Section 5.4 hereof, the Company and its Subsidiaries,
on a consolidated basis, do not have any material contingent liabilities.

         5.6     Outstanding Debt.  Neither the Company nor any of its
Subsidiaries has outstanding any Debt except as permitted by Section 6.10(b)
and as set forth on Schedule 5 attached hereto and made a part hereof.  There
exists no default under the provisions of any instrument evidencing Debt or of
any agreement relating thereto.

         5.7     Title to Properties.  Except for assets which are the subject
of capitalized lease obligations, the Company and its Subsidiaries each have
and will continue to have good and marketable title to their respective
properties and assets, including the properties and assets reflected in the
financial statements described in Section 5.4 hereof, subject to no Lien of any
kind except Liens permitted by Section 6.10(a) hereof.  All leases necessary in
any material respect for the conduct of the





                                    -  15  -
<PAGE>   20
respective businesses of the Company and its Subsidiaries are valid and
subsisting and are in full force and effect.

         5.8     Purpose.  The proceeds of the Loan will be used by the
Companies only for the purposes specified in Section 1.4 hereof.

         5.9     Margin Stock.  Neither the Company nor any of its Subsidiaries
is engaged in the business of purchasing or selling margin stock (as defined in
any regulation of the Board of Governors of the Federal Reserve System) or
extending credit to others for the purpose of purchasing or carrying margin
stock and no part of the proceeds of any borrowing hereunder will be used to
purchase or carry any margin stock or for any other purpose which would violate
any of the margin regulations of such Board of Governors.

         5.10    ERISA.  No accumulated funding deficiency (as defined in 
Section 302 of ERISA and Section 412 of the Code), whether or not waived,
exists with respect to any Plan (other than a Multiemployer Plan).  No
liability to the PBGC has been or is expected by the Company to be incurred
with respect to any Plan (other than a Multiemployer Plan) by the Company or
any of its Subsidiaries which is or would be materially adverse to the Company
and its Subsidiaries taken as a whole.  Neither the Company nor any of its
Subsidiaries has incurred or presently expects to incur any withdrawal of
liability under Title IV of ERISA with respect to any Multiemployer Plan which
is or would be materially adverse to the Company and its Subsidiaries taken as
a whole.  The execution and delivery of this Agreement will not, and the
delivery of the Notes will not, involve any transaction which is subject to the
prohibitions of Section 406 of ERISA or in connection with which a tax could be
imposed pursuant to Section 4975 of the Code.  The term "Code" shall  mean the
Internal Revenue Code of 1986, as amended; the term "Plan" shall mean an
"employee pension benefit plan" (as defined in Section 3 of ERISA) which is or
has been established or maintained, or to which contributions are or have been
made, by the Company or by any trade or business, whether or not incorporated,
which, together with the Company, is under common control, as described in
Section 414(b) or (c) of the Code; and the term "Multiemployer Plan" shall mean
any plan which is a "multiemployer plan" (as such term is defined in Section
4001(a)(3) of ERISA).

         5.11    Consents.  No consent, approval or authorization of, or
registration or declaration with, any federal or state governmental authority
or other regulatory agent for the validity of the execution and delivery or for
the performance by any of the Companies of this Agreement, the Line of Credit
Notes and the Term Notes or any agreement or instrument executed in connection
herewith is or will be required.





                                    -  16  -
<PAGE>   21
         5.12    Tax Returns; Taxes.  The Company has and each of its
Subsidiaries have filed all federal, state, foreign and other income tax
returns which, to the knowledge of the officers of the Company, are required to
be filed by any jurisdiction, and each has paid and will pay all taxes which
have or subsequently become due pursuant to said returns or pursuant to any
assessments, except those contested in good faith by appropriate proceedings
and for which sufficient reserves have been or will be established.

         5.13    Compliance with Laws.  The Company and each of its Subsidiaries
is in substantial compliance with all laws and regulations applicable to the
Companies and the businesses conducted by them (including without limitation,
laws and regulations relating to pollution and environmental control, equal
employment opportunity and employer safety) in all jurisdictions in which the
Company and each of its Subsidiaries is presently doing business, and the
Company will substantially comply and cause each of its Subsidiaries to
substantially comply with all such laws and regulations which may be legally
imposed in the future in jurisdictions in which the Company or any Subsidiary
may then be doing business.

         5.14    Foreign Assets Control Regulations.  Neither the borrowing by
the Companies hereunder nor their use of the proceeds thereof will violate the
Foreign Assets Control Regulations, the Cuban Assets Control Regulations, the
Rhodesian Sanctions Regulations, the Iranian Assets Control Regulations, the
Nicaraguan Trade Control Regulations, the South African  Transactions
Regulations, the Libyan Sanctions Regulations, the Iranian Transactions
Regulations, the Panamanian Transactions Regulations, Iraqi Sanctions
Regulations, the Kuwaiti Assets Control Regulations, the Haitian Transactions
Regulations or the Federal Republic of Yugoslavia (Serbia and Montenegro)
Sanctions Regulations of the United States Treasury Department (31 CFR,
Subtitle B, Chapter V), or the Comprehensive Anti-Apartheid Act of 1986 (P.L.
99-440), or any similar asset control regulations now existing or hereafter
promulgated by the United States Treasury Department.

         5.15    Disclosure.  Neither this Agreement nor any other document,
certificate or statement furnished to the Lenders by or on behalf of the
Company and the Subsidiaries in connection herewith contains any untrue
statement of a material fact or omits to state a material fact necessary in
order to make the statements contained herein and therein not misleading.
There is no fact peculiar to the Company or any of its Subsidiaries which
materially adversely affects or in the future may (so far as the Company can
now foresee) materially adversely affect the business, property or assets, or
financial condition, of the Company and any of its Subsidiaries, taken as a
whole, and which has not been set forth in





                                    -  17  -
<PAGE>   22
this Agreement or in the other documents, certificates and statements furnished
to you by or on behalf of the Company prior to the date hereof in connection
with the transactions contemplated hereby.

         5.16    Environmental Matters.  (i) Neither the Company nor any
Subsidiary is subject to any Environmental Liability or Environmental
Requirement which could reasonably be expected to  have a material adverse
effect on the business, financial condition, operations or prospects of the
Company and its Subsidiaries, taken as a whole.

         (ii)  Except as set forth on Schedule 7-Part 1, neither the Company
nor any Subsidiary has been designated as a potentially responsible party under
CERCLA or under any state statute similar to CERCLA.  None of the Properties
has been identified on any current or proposed National Priorities List under
40 C.F.R. Section 300 or any list arising from a state statute similar to
CERCLA.  None of the Properties has been identified on any CERCLIS list.

         (iii)  No Hazardous Materials have been or are being used, produced,
manufactured, processed, generated, stored, disposed of, released, managed at
or shipped or transported to or from the Properties or are otherwise present
at, on, in or under the Properties or, to the best knowledge of the Companies,
at or from any adjacent site or facility, except for Hazardous Materials used,
produced, manufactured, processed, generated, stored, disposed of, released and
managed in the ordinary course of business in compliance with all applicable
Environmental Requirements, except where failure to comply could not reasonably
be expected to have a material adverse affect on the business, operations, or
financial condition of the Company and its Subsidiaries, taken as a whole.

         (iv)  Except as set forth in Schedule 7-Part 2, the Company and each
of its Subsidiaries has procured all permits, licenses or authorizations (or
any variances or waivers) necessary under Environmental Requirements for the
conduct of its business.


         Section 6.  Covenants of the Companies.

                 reasonable detail and certified by an authorized financial

                 submitted to the Company or any of its Subsidiaries by
                 independent accountants in connection with any annual, interim
                 or special audit made by them of the books of the Company or
                 any of its Subsidiaries and which the Company or any of its
                 Subsidiaries shares with the audit committee of the Board of
                 Directors of the Company;

         (e)     with reasonable promptness, such other financial data as
                 Lenders may reasonably request;

         (f)     as soon as practicable and in any event within ninety (90)
                 days after the end of each fiscal year, a copy of the
                 Company's internal statement of operations by area; and

         (g)     as soon as practicable but in any event not later than ninety
                 (90) days after the beginning of each fiscal year, a

                 the ensuing fiscal year, setting forth the anticipated
                 revenues and expenses for such year, the incurrence and
                 repayment of Debt during such year, and such other matters as
                 the Lenders may reasonably require.

Together with each delivery of financial statements required by clauses (a) and
(b) above, the Company will deliver to the Administrative Agent seven originals
of an Officer's Certificate demonstrating (with computations in reasonable
detail) compliance with Sections 6.8, 6.9, 6.10(b) and 6.10(f), stating that
there exists no Event of Default or Default, or, if any such Event of Default
or Default exists, specifying the nature thereof, the period of existence
thereof and what action the Company proposes to take with respect thereto.
Together with each delivery of financial statements required by clause (b)
above, the Company will also deliver to the Administrative Agent seven
originals of a certificate of said accountants stating that, in making the
audit necessary to the certification of such financial statements, they have
obtained no knowledge of any Default or any Event of Default, or, if any such
Event of Default or Default exists, specifying the nature and period of
existence thereof.  Such accountants, however, shall not be liable to anyone by
reason of their failure to obtain knowledge of any such Event of Default or
Default which would not be disclosed in the course of an audit conducted in
accordance with generally accepted auditing standards.

                          manner draws into question the validity of or is
                          likely to impair the ability of the Companies to

             (vi)         any (A) Environmental Liability which is likely to

the Company will deliver to the Administrative Agent an Officer's Certificate
specifying the nature and period of existence thereof and what action the
Company has taken, is taking or proposes to take with respect thereto.

         The Administrative Agent will promptly distribute to the Lenders,
originals (to the extent available) or copies of the financial statements and
reports, the Officer's Certificates and all other documents received by the
Administrative Agent from the Borrower pursuant to this Section 6.1.

         6.2     Inspection of Property.  The Companies agree that they will
permit the Administrative Agent, each Lender (with prior notice to the
Administrative Agent) and any Person designated by the Administrative Agent in
writing, at Administrative Agent's (or Lender's) expense, to visit and inspect
any of the properties of the Company and its Subsidiaries, to examine the
corporate books and financial records of the Companies and make copies thereof
or extracts therefrom, and to discuss the affairs, finances and accounts of any
of such corporations with the principal officers of each of the Companies and
their respective independent public accountants, all at such reasonable times
and as often as Administrative Agent or the Lenders may reasonably request.

         6.3     Covenant to Secure Notes Equally.  (a) The Companies agree
that if the Company or any Subsidiary shall create or assume any Lien of any
kind upon any of its property or assets, whether now owned or hereafter
acquired, other than Liens permitted by the provisions of Section 6.10(a)
(unless prior written consent to the creation or assumption thereof shall have
been obtained), they will make or cause to be made effective provisions whereby
the Notes will be secured by such Lien equally and ratably with any and all
other Debt thereby secured, as long as any such other Debt shall be so secured.

         (b)     The Companies agree not to become a party to, or otherwise be
subject to, any provision contained in any instrument evidencing indebtedness
of any of the Companies which imposes restrictions on the granting of Liens by
the Companies on otherwise unencumbered assets of the Companies as security for
the Notes, except as set forth herein.

         6.4     Guaranteed or Collateralized Obligations.  The Company agrees
that if it or any of its Subsidiaries incurs or permits to exist any Debt in
any event in excess of an aggregate principal amount equal to $5,000,000
guaranteed or collateralized (except as permitted by Section 6.10(a)(ix)
hereof) in any other manner by any Person (other than any governmental entity,
or other than in connection with (y) bonds, letters of credit, letters of
undertaking, or other instruments related to litigation, or the





                                    -  22  -

avoidance thereof, involving the Company or its Subsidiaries, including the
release of assets of the Company or its Subsidiaries in connection with such
litigation, or (z) performance bonds,  surety bonds, letters of credit, bank
guaranties, and other instruments related to the conduct of the business of the
Company or its Subsidiaries, excluding any obligation for borrowed money), it
will simultaneously cause such Person to execute and deliver to  the Lenders a
guaranty agreement or collateral agreement, as the case may be, in form and
substance satisfactory to the Lenders either (i) guaranteeing payment of the
principal amount of the Notes and any premium and interest thereon, which bears
the same ratio to the total unpaid principal amount of the Notes as the amount
of such other obligation which is guaranteed bears to the total unpaid
principal amount of such other obligation or (ii) collateralizing the Notes
equally and ratably with such other obligation, as the case may be.  Nothing
contained in the foregoing shall be deemed to permit the Companies to incur
Liens to Persons other than the Lenders in excess of those permitted by Section
6.10(a) hereof.

         6.5     Maintenance of Insurance.  Each Company agrees that it and
each Subsidiary will maintain, with responsible insurers, insurance with
respect to its properties and business against such casualties and
contingencies (including, but not limited to, public liability, larceny,
embezzlement or other criminal misappropriation, pollution and war risks) and
in such amounts as is customary in the case of similarly situated corporations
engaged in the same or similar businesses.

         6.6     Maintenance of Corporate Existence/Compliance with
Law/Preservation of Property.  Except as allowed under Sections 6.10(d) and
6.10(e), each Company covenants that it and each Subsidiary will do or cause to
be done all things necessary to preserve, renew and keep in full force and
effect the corporate existence of such Company and its Subsidiaries and comply
in all material respects with all laws and regulations (including, without
limitation, laws and regulations relating to equal employment opportunity and
employee safety) applicable to it and its Subsidiaries, the failure with which
to comply is likely to materially adversely affect the business, operations or
financial condition of such Company and its Subsidiaries, taken as a whole; at
all times maintain, preserve and protect all material intellectual property of
such Company and its Subsidiaries, and preserve all the remainder of its
material property used or useful in the conduct of its business and keep the
same in good repair, working order and condition.

         6.7     Compliance with Environmental Laws.  Each of the Companies
will, and the Company will cause each of its Subsidiaries to, comply in a
timely fashion with, or operate pursuant to valid





                                    -  23  -
<PAGE>   28
waivers of the provisions of, all Environmental Requirements including, without
limitation, requirements with respect to the emission of wastewater effluent,
solid and hazardous waste and air pollution, and any  other applicable
requirements for conducting, on a timely basis, periodic tests and monitoring
for contamination of ground water, surface water, air and land and for
biological toxicity of the aforesaid, and comply with any applicable
regulations (except to the extent such regulations are waived by appropriate
governmental authorities) of the Environmental Protection Agency or other
relevant federal, state or local governmental authority, except where the
failure to do so is not likely to materially adversely affect the business,
operations or financial condition of the Company and the Subsidiaries, taken as
a whole.  To the fullest extent permitted by applicable law, each Company
agrees to indemnify and hold the Agents, the Lenders, their officers, agents
and employees harmless from any loss, liability, claim or expense that they may
incur or suffer as a result of a breach by the Company or any of the
Subsidiaries, as the case may be, of this covenant.  No Company shall be deemed
to have breached or violated this Section 6.7 if such Company or Subsidiary is
challenging in good faith by appropriate proceedings diligently pursued the
application or enforcement of such Environmental Requirements for which
adequate reserves have been established in accordance with generally accepted
accounting principles.

         6.8     Consolidated Current Assets Requirement.  The Companies agree
that they will not permit Consolidated Current Assets to be less than 150% of
Consolidated Current Liabilities at any time.

         6.9     Dividend, Payment, Redemption and Other Limitations.  The 
Company agrees that it will not (i) pay or declare any dividend on any class of
its stock; (ii) make any other distribution on account of any class of its
stock; (iii) redeem, purchase or otherwise acquire, directly or indirectly, any
shares of its stock; (iv) make any payments of principal of, or retire, redeem,
purchase or otherwise acquire, any Subordinated Debt; or (v) permit any
Subsidiary to make any payment on account of, or purchase or otherwise acquire,
any shares of stock of any of the Companies or make any Restricted Investments
(all of the foregoing clauses (i) through (v) being herein called "Restricted
Payments") except in all such cases out of Consolidated Net Earnings Available
for Restricted Payments; provided, however, the Company will not, and will not
permit any Subsidiary to, make any Restricted Payment if a Default or Event of
Default then exists or if such Restricted Payment would cause a Default or an
Event of Default  to exist.  There shall not be included in Restricted Payments
or in any computation of Consolidated Net Earnings Available for Restricted
Payments:  (w) dividends paid by a Domestic Subsidiary to another Domestic
Subsidiary or to the Company or dividends paid by a Foreign Subsidiary to
another Subsidiary or to any of the Companies; (x) dividends paid, or
distributions made, in stock of

the Company; (y) exchanges of stock of one or more classes of the Company,
except to the extent that cash or other value is involved in such exchange; or
(z) dividends of purchase rights pursuant to the Shareholder Rights Agreement,
as amended and restated on December 17, 1993, and redemption of any rights that
may be distributed pursuant to such Shareholder Rights Agreement to the extent
that the aggregate of all amounts paid by the Company for the redemption of
such rights do not exceed $1,250,000.  The term, "stock", as used in this
Section 6.9 shall include warrants or options to purchase stock.

         6.10    Liens, Debt and Other Restrictions.  The Companies agree that
they will not and will not permit any Subsidiary to:

                 (a)      Liens.  Create, assume or suffer to exist any Lien
         upon any of their respective property or assets, whether now owned or
         hereafter acquired (whether or not provision is made for the equal and
         ratable securing of the Credit in accordance with the provisions of
         Section 6.3) except:

              (i)         Liens for taxes (including ad valorem and property
                          taxes) not yet due or which are being contested in
                          good faith by appropriate proceedings;

             (ii)         Liens incidental to the conduct of their businesses
                          or the ownership of their property and assets which
                          were not incurred in connection with the borrowing of
                          money or the obtaining of advances of credit, and
                          which do not in the aggregate materially detract from
                          the value of their property or assets or materially
                          impair the use thereof in the operation of their
                          business;

            (iii)         presently existing Liens on property or assets of any
                          of the Subsidiaries to secure obligations of any of
                          such Subsidiaries to the Company or another
                          Subsidiary;

             (iv)         presently existing Liens on property or assets of any

                          constructed, which Liens were required as a condition
                          of new vessel financing from non-United States
                          sources, all of which Liens (other than Liens which
                          are incidental and do not materially affect such

                          time of acquisition upon any real or personal
                          property acquired by the Company or any Subsidiary

                          otherwise, whether or not assumed by the Company or
                          any Subsidiary, or placed upon real or personal
                          property acquired by the Company or any Subsidiary,

                          Liens (other than Liens which are incidental and do
                          not materially affect such property) are set forth on

provided, however, the foregoing shall not restrict the incurrence of Debt by
any of the Companies to any Subsidiary or by any Subsidiary to any of the
Companies or to any other Subsidiary that arises in the ordinary course of the
business of such Subsidiary.

authorizes the Administrative Agent to receive all payments of principal,
interest, fees and other amounts payable by the Companies under this Agreement

obligated to fund Credit Facility Advances and the Compression Term Loan in
proportion to their Commitments.  The Administrative Agent may resign at any
time by written notice to the Lenders; the successor Administrative Agent shall

directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken by it or them under or in  connection with this
Agreement and the Notes, except for its or their own gross negligence or
willful misconduct.  Without limitation of the generality of the foregoing, the
Agents:  (i) may treat the payee of any of the Notes as the holder thereof
until the Administrative Agent receives written notice of the assignment or
transfer thereof, signed by such payee and in form satisfactory to the
Administrative Agent; (ii) may consult with legal counsel (including counsel

it and shall not be liable for any action taken or omitted to be taken by it in

acting upon any notice, consent, certificate or other instrument or writing
(which may be by facsimile, telegram, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

         10.3     Acts by Administrative Agent after Default, etc.  In the event
that the Administrative Agent shall have been notified in writing by any of the
Companies or the Lenders of any Event of Default (or in the event that the
officer of the Administrative Agent responsible for the Borrower's account
obtains actual knowledge of an Event of Default), the Administrative Agent (a)
shall immediately notify  the Lenders; (b) shall take such action and assert
such rights under this Agreement as it is expressly required to do pursuant to
the terms of this Agreement with the consent of the Required Lenders; (c) may
take such other actions and assert such other rights as it deems advisable, in
its discretion, for the protection of the interests of the Lenders pursuant to
applicable laws with the consent of the Required Lenders; and (d) shall inform
all the Lenders of the taking of action or assertion of rights pursuant to this
Section.  Each Lender agrees with the Administrative Agent and the other
Lenders that the decisions and determinations of the Required Lenders in
enforcing this Agreement and the Notes and guiding the Administrative Agent in
those matters shall be binding upon all the Lenders, including, without
limitation, authorizing the Administrative Agent at the pro rata expense of all
the Lenders (to the extent not reimbursed by the Companies) to retain attorneys
to seek  judgment on this Agreement and the Notes.  Each Lender agrees with the
other Lenders that it will not, without the consent of the other Lenders,
separately seek to institute any legal action with respect to the Loan;
provided that following the maturity of the Notes (whether by acceleration or
at stated maturity), each Lender may, without the concurrence of the other
Lenders, separately seek to institute any legal action with respect to the
Loan.

independently and without reliance upon the Agents or any other Lender and
based on the financial statements referred to in Section 5.4 hereof and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Lender also
acknowledges that it will, independently and without reliance upon the Agents
or any other Lender and based on such documents and information as it





                                    -  38  -

shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement and the Notes.

         10.5     Agents.  Agents shall have the same rights and powers under 
this Agreement and the Notes as any other Lender and may exercise the same as
though it were not the Agents; and the term "Lender" or "Lenders" shall, unless
otherwise expressly indicated, include Agents in its individual capacity.
Agents may accept deposits from, lend money to, act as trustee under indentures
of, and generally engage in any kind of business with the Company as if Agents
were not the Agents and without any duty to account therefor to the Lenders.

foreign taxation or bank regulation.  Upon satisfaction of each of the

exercising any  rights hereunder or under any Note shall operate as a waiver of
any rights of any of the Lenders.  In the case of a waiver or consent, such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.

         11.12  Entire Agreement.  This Agreement constitutes the entire
