                         NOTES TO FINANCIAL STATEMENTS
                (DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)

NOTE 1 - BASIS OF PRESENTATION - These consolidated financial statements should
be read in the context of the consolidated financial statements and notes
thereto filed with the Commission in the Company's 1996 annual report on Form
10-K.  In the opinion of management, the accompanying unaudited consolidated
financial statements reflect all adjustments, consisting only of normal
adjustments, necessary to present fairly the financial position of Union Texas
Petroleum Holdings, Inc. and its consolidated subsidiaries at March 31, 1997,
and the results of operations and cash flows for the three months ended March
31, 1997 and 1996.  The results of operations for the three months ended March
31, 1997, should not necessarily be taken as indicative of the results of
operations that may be expected for the entire year 1997.

NOTE 2 - CREDIT FACILITIES - The Company had two unsecured bank credit
facilities (the "Credit Facilities") at March 31, 1997.  One of the Credit
Facilities is a $100 million revolver that provides for conversion of amounts
outstanding on March 10, 1998 to a one-year term loan maturing March 9, 1999.
Another Credit Facility is a $450 million revolver that reduces quarterly by
$35 million beginning June 30, 2001, with a final maturity of March 31, 2002.
In addition to such Credit Facilities, the Company has the ability to obtain
short-term borrowings on uncommitted and unsecured lines of credit with several
banks.

NOTE 3 - CONTINGENCIES - The Company and its subsidiaries and related companies
are named defendants in a number of lawsuits and named parties in numerous
government proceedings arising in the ordinary course of business.  While the
outcome of contingencies, lawsuits or other proceedings against the Company
cannot be predicted with certainty, management expects that any liability, to
the extent not provided for through insurance or otherwise, will not have a
material adverse effect on the financial statements of the Company.

                      UNION TEXAS PETROLEUM HOLDINGS, INC.

With respect to the unaudited consolidated financial information of Union Texas
Petroleum Holdings, Inc. for the three- month periods ended March 31, 1997 and
1996, Price Waterhouse LLP reported that they have applied limited procedures
in accordance with professional standards for a review of such information.
However, their separate report dated April 22, 1997 appearing below, states
that they did not audit and they do not express an opinion on that unaudited
consolidated financial information.  Price Waterhouse LLP has not carried out
any significant or additional audit tests beyond those which would have been
necessary if their report had not been included.  Accordingly, the degree of
reliance on their report on such information should be restricted in light of
the limited nature of the review procedures applied.  Price Waterhouse LLP is
not subject to the liability provisions of section 11 of the Securities Act of
1933 for their report on the unaudited consolidated financial information
because that report is not a "report" prepared or certified by Price Waterhouse
LLP within the meaning of sections 7 and 11 of the Act.


                        INDEPENDENT ACCOUNTANT'S REPORT


To the Board of Directors
of Union Texas Petroleum Holdings, Inc.



We have reviewed the accompanying consolidated balance sheet of Union Texas
Petroleum Holdings, Inc. and consolidated subsidiaries as of March 31, 1997 and
the related consolidated statements of operations and of cash flows for the
three month periods ended March 31, 1997 and 1996.  This financial information
is the responsibility of the Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical review
procedures to financial data and making inquiries of persons responsible for
financial and accounting matters.  It is substantially less in scope than an
audit conducted in accordance with generally accepted auditing standards, the
objective of which is the expression of an opinion regarding the financial
statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying financial information for it to be in conformity
with generally accepted accounting principles.

We previously audited in accordance with generally accepted auditing standards,
the consolidated balance sheet as of December 31, 1996, and the related
consolidated statements of operations, of cash flows, and of stockholders'
equity for the year then ended (not presented herein), and in our report dated
February 14, 1997 we expressed an unqualified opinion on those consolidated
financial statements.  In our opinion, the information set forth in the
accompanying consolidated balance sheet information as of December 31, 1996, is
fairly stated in all material respects in relation to the consolidated balance
sheet from which it has been derived.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the financial
statements, notes, and management's discussion contained in the registrant's
1996 annual report on Form 10-K, and condensed financial statements and notes
contained in this report.


RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1997 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1996

Net income for the three months ended March 31, 1997, was $64 million, or $.74
per share as compared to net income of $48 million, or $.54 per share reported
for the same period in 1996.  The current quarter was favorably impacted by
higher worldwide oil prices, higher LNG and gas prices, higher U.K. oil volumes
and lower interest expense partially offset by lower LNG volumes.  

Sales and operating revenues for the three months ended March 31, 1997, were
$282 million, as compared to $258 million for the first quarter of 1996.
International revenues totaled $234 million as compared to $217 million for the
first quarter of 1996.  In the U.K., sales and operating revenues increased by
$16 million due to higher crude oil prices and increased sales volumes,
including higher gas takes from the Sean fields.  In Indonesia, sales decreased
$2 million due to lower LNG and oil volumes partially offset by higher prices.
For the full year, LNG sales volumes are expected to be approximately 15% below
1996 levels.  In Pakistan, sales were $3 million above 1996 primarily due to
higher crude oil and gas prices.

Average prices received and volumes sold by the Company's major operations
during the first quarter of 1997 and 1996, respectively, were as follows:

</TABLE>

Petrochemical revenues totaled $48 million as compared to $41 million in the
first quarter of 1996, while operating profit was $1 million as compared to $4
million in the prior period.  The revenue increase was principally due to
higher ethylene sales prices, however, higher feedstock cost and pipeline
maintenance expense offset the revenue increase.

Interest expense in the first quarter of 1997 was lower than the same period of
1996 due to a reduction in the Company's debt level.  Lower exploration
expenses were primarily due to reduced exploration costs in Alaska.

FINANCIAL CONDITION

Cash flow from operations:  Net cash provided by operating activities was $83
million in the first quarter of 1997, a decrease of $13 million from the same
period in the prior year.  The decline was due mainly to the timing of U.K. tax
payments and lower Indonesian LNG volumes, partially offset by higher product
prices.

Capital resources:  Capital expenditures for the first quarter of 1997 were $33
million including capitalized interest of $8 million. Capital expenditures for
the first quarter of 1996 were $45 million including capitalized interest of $6
million.  The current quarter decrease was due to lower Alaska exploration
drilling and reduced development costs for the Britannia field in the U.K.
North Sea.

Financing activities:  The Company had two unsecured credit facilities (the
"Credit Facilities") at March 31, 1997.  One of the Credit Facilities is a $100
million revolver that provides for conversion of amounts outstanding on March
10, 1998 to a one-year term loan maturing March 9, 1999. This facility replaced
a $100 million unsecured credit agreement that matured on March 15, 1997.  The
other Credit Facility is a $450 million revolver that reduces quarterly by $35
million beginning June 30, 2001,  with a final maturity of March 31, 2002.   At
March 31, 1997, no amounts were outstanding under the Credit Facilities.  The
$450 million revolver allows the Company to borrow up to $300 million in U.S.
dollar loans at interest rates determined in a competitive bid process.  Loans
under the $450 million revolver may be made in both pounds sterling and U.S.
dollars at the option of the Company.  Loans under the Credit Facilities bear
interest at floating market rates based on, at the Company's option, the agent
bank's base rate or LIBOR, plus applicable margins, subject to increase or
decrease in certain events.  The Credit Facilities contain restrictive
covenants, including maintenance of certain coverage ratios related to the
incurrence of additional indebtedness and limitations on asset sales and
mergers or consolidations.  The covenants also require maintenance of
stockholders' equity, as adjusted, at $350 million.  Under the terms of the
Credit Facilities, the Company may pay dividends and make stock repurchases
provided that such level of minimum stockholders' equity is maintained and the
Company complies with certain other covenants in the Credit Facilities.  At
March 31, 1997, the Company's adjusted stockholders' equity was approximately
$635 million.  The Credit Facilities provide the Company with the ability to
borrow on a long-term basis.

The Company has established short-term, uncommitted and unsecured lines of
credit with several banks in both U.S. dollars and pounds sterling. These money
market borrowings, which have a short-term maturity, have been classified as
long-term debt based on the Company's ability to refinance them on a long-term
basis through its Credit Facilities.  At March 31, 1997, $13 million was
outstanding under these money market lines.  As of March 31, 1997, the Company
had approximately $537 million of available financing under the Credit
Facilities.

The Company's indirect subsidiary, Union Texas Britannia Limited ("UTBL"), has
a 150 million pounds sterling secured financing from a syndicate of banks.  The
financing is used to fund the Company's share of the cost of developing the
Britannia field to production.  At March 31, 1997, 63 million pounds sterling
($103 million) was outstanding under UTBL's financing which bore interest at a
weighted average rate of 7.0% per annum.

In 1994, the Company's Board of Directors authorized the repurchase of up to
2,000,000 shares of the Company's common stock, all of which were repurchased
by the end of 1996. In October, 1996, the Company's Board of Directors
authorized the repurchase of up to an additional 2,000,000 shares of the
Company's common stock, all of which were repurchased by March 31, 1997.
During the first quarter of 1997, the Company repurchased a total of 1,821,264
shares at an average price of $18.84 per share.  The repurchased stock will be
used for general corporate purposes, including fulfilling employee benefit
program obligations.  At March 31, 1997, 3,206,366 shares of common stock were
held, at cost, as treasury shares.  

Financial condition:  In the first quarter of 1997 the Company declared and paid
a dividend of approximately $4.3 million on its common stock.  On April 16, 1997
the Company announced a dividend on its common stock of $.05 per share to
stockholders of record as of April 30, 1997, payable on May 15, 1997.

                          PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS

The Company and its subsidiaries and related companies are named defendants in
numerous lawsuits and named parties in numerous governmental proceedings
arising in the ordinary course of business.  While the outcome of lawsuits or
other proceedings against the Company cannot be predicted with certainty,
management does not expect these matters to have a material adverse effect on
the financial statements of the Company.  (See Item 3 in the Company's 1996
annual report on Form 10-K.)

ITEM 5 - OTHER INFORMATION

Indonesia.  The Company's Indonesian activities consist primarily of its 37.81%
working interest in an East Kalimantan joint venture that supplies natural gas
to a liquefied natural gas ("LNG") plant at Bontang Bay owned by Pertamina, the
Indonesian national oil company.  In March 1997, a $1,127 million financing was
signed for the eighth train (Train H), an additional LNG storage tank, an
additional natural gas pipeline from the Badak field to the LNG plant, and a
debottlenecking project for Trains A through F.  The financing was provided by
a combination of Taiwanese and Japanese sources and a group of international
banks through arrangements similar to those used to finance the seventh train
(Train G).  The financing provides for initial advances of up to $150 million,
with further advances being conditioned upon the execution and delivery of the
marine transportation agreement associated with the Badak VI Sales Contract.
Construction is expected to begin in 1997.  Revenues from the Badak V Sales
Contract with Korea Gas Corporation and the Badak VI Sales Contract with
Chinese Petroleum Corporation will be the primary sources of repayment for this
financing.  Financing for the eighth train is nonrecourse to both Pertamina and
the joint venture.

hereby amended as follows:

                 1.1.  Section 1.01.  The following respective definitions set
forth in Section 1.01 of the Agreement are hereby amended to read as follows:

                 "Commitment" means, with respect to each Bank, the amount set
         forth opposite the name of such Bank on the signature pages of the
         First Amendment (or, if such Bank is an Assignee and its name is not
         set forth on the signature pages of the First Amendment, the amount of
         its Commitment as set forth in the Assignment pursuant to which it
         became a Bank), as such amount may be reduced from time to time
         pursuant to Sections 2.09 and 2.10 or reduced or increased from time
         to time pursuant to any Assignment to which it is a party.

                 "Excluded Subordinated Debt" means Debt that (i) is
         subordinate and junior, on terms reasonably satisfactory to the Agent,
         to the Loans in all respects and (ii) has no requirement, absent a
         default under such Debt, that any principal thereof be paid,
         purchased, redeemed, defeased, acquired, exchanged or converted (other
         than exchange for or conversion to common stock of the Company) prior
         to March 31, 2003.

                 "Restricted Preferred Stock" means (i) all preferred stock
         which (a) is subject to purchase, retirement, redemption, exchange or
         conversion (other than exchange for or conversion to common stock of
         the Company), in whole or in part under any circumstance whatsoever
         (other than purchase, retirement, redemption, exchange or conversion
         by the issuer thereof, at the sole option of such issuer, if failure
         to exercise such option would not have an adverse effect on the
         Company or any Subsidiary pursuant to the terms of any such preferred
         stock or any documents related thereto) and (b) provides for dividends
         materially in excess of the generally prevailing market dividend rate

         would not have an adverse effect on the Company or any Subsidiary
         pursuant to the terms of any such preferred stock or any documents
         related thereto).  For avoidance of doubt, to the extent that any
         shares of Restricted Preferred Stock are exchanged for or converted to
         common stock of the Company and as a consequence such shares of
         Restricted Preferred Stock are cancelled, such shares shall no longer
         constitute Restricted Preferred Stock.

                 "Short-Term Credit Agreement" means the Credit Agreement dated
         as of March 11, 1997 among the Company, NationsBank of Texas, N.A., as
         agent, and the co-Agents and the banks parties thereto, providing a
         $100,000,000 credit facility to the Company, as may be amended or

         of March 11, 1997 executed by the Company, the Agent, the Co-Agents
         and the Banks.

                 1.2.     Section 4.04.  Section 4.04 of the Agreement is
hereby amended by replacing both (i) the reference in subsection (a) to the

reference in subsections (a) and (c) to the term "Company's 1995 Form 10-K"
with the term "Company's 1996 Form 10-K".

                                   ARTICLE II

                                  THE CREDITS

         SECTION 2.01.  Commitments to Lend.  During the Revolving Credit
Period each Bank severally agrees, on the terms and conditions set forth in
this Agreement, to make loans to the Company pursuant to this Section from time
to time in amounts such that the aggregate principal amount of Loans by such
Bank at any one time outstanding to the Company shall not exceed the amount of
such Bank's Commitment at such time.  Each Borrowing under this Section shall
be in an aggregate principal amount of $10,000,000 or any larger multiple of
$1,000,000 (except that any such Borrowing may be, subject to the other terms
hereof, in the aggregate amount of the remaining unused Commitments) and shall
be made from the several Banks ratably in proportion to their respective
Commitments.  Within the foregoing limits, the Company may borrow under this
Section, repay (whether pursuant to Section 2.10 or otherwise), or to the
extent permitted by Section 2.11, prepay Loans and reborrow at any time during
the Revolving Credit Period under this Section.

         SECTION 2.02.  Notice of Borrowings.  (a) The Company shall give the
Agent notice (a "Notice of Borrowing") not later than 10:00 A.M. (Houston time)
on (x) the date of each Base Rate Borrowing, and (y) the third Euro-Dollar
Business Day before each Euro-Dollar Borrowing, specifying:

         (i) the date of such Borrowing, which shall be a Domestic Business Day
    in the case of a Base Rate Borrowing or a Euro-Dollar Business Day in the
    case of a Euro-Dollar Borrowing,

         (ii)    the aggregate amount of such Borrowing,

         (iii)   whether the Loans comprising such Borrowing are to be Base
    Rate Loans or Euro-Dollar Loans, and

         (iv)    in the case of a Euro-Dollar Borrowing, the duration of the
    initial Interest Period applicable thereto, subject to the provisions of
    the definition of Interest Period.

Notwithstanding the foregoing, not more than ten Euro-Dollar Borrowings shall
be outstanding at any one time, and any Borrowing which would exceed such
limitation shall be made as a Base Rate Borrowing.

         (b) If requested to do so by the Company through the Agent at least
ten Euro-Dollar Business Days before the first day of a proposed Interest
Period for Euro-Dollar Loans, each Bank will advise the Agent before 10:00 A.M.
(Houston time) on the sixth Euro-Dollar Business Day preceding the date of such
proposed Interest Period as to whether, if the Company selects a specified
duration of nine or twelve months for such Interest Period, such Bank expects
that deposits in dollars with a corresponding term will be available to it in
the relevant market on the first day of such Interest Period in the amount
required to fund its Loan to which such Interest Period would apply.  Unless a
Bank responds by such time to the effect that it expects such deposits will not
be available to it, the Company shall be entitled to select such proposed
duration for such Interest Period.

         SECTION 2.03.  Conversions.  (a)  The Company may on any Euro-Dollar
Business Day, upon notice given to the Agent no later than 10:00 A.M. (Houston
time) on the third Euro-Dollar Business Day prior to the date of the proposed
Conversion and subject to the provisions of Section 2.02 and Article VIII and
the other provisions hereof, Convert all Loans comprising one or more
Borrowings; provided that (i) Loans comprising a Borrowing may not be Converted
if after giving effect to such Conversion, such Borrowing would be a Euro-
Dollar Borrowing and the outstanding principal amount of such Borrowing would
be less than $10,000,000 and (ii) no Conversion (other than changing Euro-
Dollar Loans into Base Rate Loans) may be made if any Event of Default is then
existing.  Each





                                      -22-
<PAGE>   29
such notice of a Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the Loans to be Converted, (iii)
if after giving effect to such Conversion, such Borrowing would be a
Euro-Dollar Borrowing, the commencement date and duration of the proposed
Interest Period for each Loan comprising such Borrowing, and (iv) the nature of
such Conversion (i.e., whether such Conversion is a change of Loans of one Type
into another Type, a continuation of Euro-Dollar Loans as such for an
additional Interest Period or an election to change an Interest Period).  Each
such notice shall be irrevocable.

         (b) If the aggregate unpaid principal amount of Euro-Dollar Loans
comprising any Borrowing shall be reduced by payment or prepayment or
otherwise, to less than $10,000,000, such Loans shall automatically, on the
last day of the then existing Interest Period therefor, Convert into Base Rate
Loans.

         (c) If the Company shall fail to select the duration of any Interest
Period for any Euro-Dollar Loans in accordance with the provisions contained in
the definition of "Interest Period" in Section 1.01, or if there shall be any
Event of Default, such Loans will automatically on the last day of the then
existing Interest Period therefor, Convert into Base Rate Loans.

         SECTION 2.04.  Notice to Banks; Funding of Loans.

         (a) Upon receipt of a Notice of Borrowing, the Agent shall promptly,
(by no later than 10:30 A.M. (Houston time) by telephone or facsimile
transmission) notify each Bank of the contents thereof and of such Bank's share
of such Borrowing and such Notice of Borrowing shall not thereafter be
revocable by the Company.

         (b) Not later than 12:00 Noon (Houston time) on the date of each
Borrowing, each Bank shall (except as provided in subsection (c) of this
Section) make available its share of such Borrowing, in Federal or other funds
immediately available in Houston, to the Agent at its address specified in or
pursuant to Section 9.01.  Unless the Agent determines that any applicable
condition specified in Article III has not been satisfied, the Agent will make
the funds so received from the Banks available to the Company at the Agent's
aforesaid address.

         (c) If any Bank makes a new Loan hereunder to the Company on a day on
which the Company is to repay all or any part of an outstanding Loan from such
Bank, such Bank shall apply the proceeds of its new Loan to make such repayment
and only an amount equal to the difference (if any) between the amount being
borrowed by the Company and the amount being repaid shall be made available by
such Bank to the Agent as provided in subsection (b), or remitted by the
Company to the Agent as provided in Section 2.12, as the case may be.





                                      -23-
<PAGE>   30
         (d) Unless the Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsections (b) and (c) of this Section 2.04 and the Agent may,
in reliance upon such assumption, make available to the Company on such date a
corresponding amount.  If and to the extent that such Bank shall not have so
made such share available to the Agent, such Bank and the Company severally
agree to repay to the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Company until the date such amount is repaid to the Agent, at
(i) in the case of the Company, a rate per annum equal to the higher of the
Federal Funds Rate and the interest rate applicable thereto pursuant to Section
2.07 and (ii) in the case of such Bank, the Federal Funds Rate.  If such Bank
shall repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

         SECTION 2.05.  Notes.
(a)  The Loans of each Bank to the Company shall be evidenced by a single Note
of the Company payable to the order of such Bank for the account of its
Applicable Lending Office in an amount equal to the aggregate unpaid principal
amount of such Bank's Loans to the Company.

         (b) Each Bank may, by notice to the Company and the Agent, request
that its Loans of a particular Type payable to such Bank (or such lending
office, agency or branch of such Bank as such Bank may specify in such request)
be evidenced by a separate Note of the Company in an amount equal to the
aggregate unpaid principal amount of such Loans.  Each such Note shall be in
substantially the form of Exhibit A hereto with appropriate modifications to
reflect the fact that it evidences solely Loans of the relevant Type.  Any Bank
that receives multiple Notes pursuant to this Section 2.05(b) agrees that: (1)
the aggregate principal amount payable by the Company under such Notes shall
never exceed the aggregate principal amount of the Loans owed to such Bank
(including, if applicable, the separate lending offices, agencies or branches
of such Bank) and (2) the payees of the Notes issued at the request of such
Bank shall enjoy no greater rights (voting or otherwise) than such Bank would
enjoy in the absence of such request and such payees (including, if applicable,
the separate lending offices, agencies or branches of such Bank) shall be
considered a single Bank for purposes of this Agreement.  Each reference in
this Agreement to the "Note" of such Bank shall be deemed to refer to and
include any or all of such Notes, as the context may require.

         (c) Upon receipt of each Bank's Note pursuant to Section 3.01(b), the
Agent shall mail or send by private delivery service such Note to such Bank.
Each Bank shall record the date, amount and Type of each Loan made by it to the
Company and the date and amount of each payment of principal made with respect
thereto, and prior to any transfer





                                      -24-
<PAGE>   31
of its Note shall endorse on the schedule forming a part thereof appropriate
notations to evidence the foregoing information with respect to each such Loan
then outstanding; provided that the failure of any Bank to make any such
recordation or endorsement shall not affect the obligations of the Company
under any of the Financing Documents.  Each Bank is hereby irrevocably
authorized by the Company so to endorse any Note and to attach to and make a
part of any Note a continuation of any such schedule as and when required.

         SECTION 2.06.  Maturity of Loans.  Each Loan shall mature, and the
principal amount thereof shall be due and payable, on March 9, 1999.

         SECTION 2.07.  Interest Rates.  The Company shall pay interest on the
unpaid principal amount of each Loan from the date of such Loan until such
principal amount shall be paid in full, at the following rates per annum:

         (a)  If such Loan is a Base Rate Loan, for each day that such Loan is
a Base Rate Loan, at a rate per annum equal to the sum of (i) the Base Rate for
such day plus (ii) at such times as any Event of Default exists, 1%.  Such
interest shall be payable quarterly on each March 31, June 30, September 30 and
December 31 and on the date such Base Rate Loan is Converted or paid in full.
Any overdue interest on any Base Rate Loan shall bear interest, payable on
demand, for each day until paid at a rate per annum equal to the sum of 1% plus
the otherwise applicable rate for such day.

         (b) If such Loan is a Euro-Dollar Loan, at a rate per annum equal at
all times during any Interest Period for such Loan to the sum of (i) the
applicable London Interbank Offered Rate plus (ii) the Applicable Margin for
such Interest Period plus (iii) at such times as any Event of Default exists,
1%; provided that any overdue principal of or interest on any Euro-Dollar Loan
shall bear interest, payable on demand, for each day from and including the
date payment thereof was due to but excluding the date of actual payment, at a
rate per annum equal to the sum of 1% plus the higher of (x) the sum of the
London Interbank Offered Rate applicable to such Loan plus the Applicable
Margin applicable to an Interest Period of a Euro-Dollar Loan if such Euro-
Dollar Loan were to commence on such day and (y) the sum of (1) the average
(rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective
rates per annum at which one day (or, if such amount due remains unpaid more
than three Euro-Dollar Business Days, then for such other period of time not
longer than three months as the Agent may select) deposits in dollars in an
amount approximately equal to such overdue payment due to each of the Reference
Banks are offered to such Reference Bank in the London interbank market for the
applicable period determined as provided above plus (2) the Applicable Margin
applicable to an Interest Period of a Euro-Dollar Loan if such Euro-Dollar Loan
were to commence on such day (or, if the circumstances described in clause (a)
or (b) of Section 8.01 shall exist, at a rate per annum equal to the sum of 1%
plus the rate applicable to Base Rate Loans for such day).  Such





                                      -25-
<PAGE>   32
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

         The "London Interbank Offered Rate" applicable to any Interest Period
means the arithmetic average (rounded upward, if necessary, to the next higher
1/16 of 1%) of the respective rates per annum at which deposits in dollars are
offered to each of the Reference Banks in the London interbank market at
approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Loan of such Reference Bank to which such
Interest Period is to apply and for a period of time comparable to such
Interest Period.

         (c) The Agent shall determine each interest rate applicable to the
Loans hereunder.  The Agent shall give prompt notice to the Company and the
participating Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.
Upon request of the Company, the Agent shall furnish to it such information as
to its determinations hereunder as the Company may reasonably request.

         (d) Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section.  If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available
on a timely basis, the provisions of Section 8.01 shall apply.

         (e) This Section 2.07 and each other provision in any of the Financing
Documents or in any other agreement executed in connection herewith are
specifically made subject to Section 2.16.

         SECTION 2.08.  Facility Fees.
         (a) The Company shall pay to the Agent for the account of the Banks
ratably a facility fee at the rate per annum for each calendar quarter
determined as provided in Schedule I based on the Rating Level in effect on the
first day of such quarter.  Such facility fee shall accrue (i) from and
including the date of this Agreement to but excluding the earlier of the
Termination Date or the date the Commitments are otherwise terminated, on the
daily average aggregate amount of the Commitments (whether used or unused) and
(ii) from and including the earlier of the Termination Date or the date the
Commitments are otherwise terminated to but excluding the date the Loans shall
be repaid in their entirety, on the daily average aggregate outstanding
principal amount of the Loans.

         (b) Payments.  Accrued fees under this Section 2.08 shall be payable
quarterly on each March 31, June 30, September 30 and December 31 and upon the
date of





                                      -26-
<PAGE>   33
termination of the Commitments in their entirety (and, if later, the date the
Loans shall be repaid in their entirety).

         SECTION 2.09.  Optional Termination or Reduction of Commitments.  The
Company may, upon at least three Domestic Business Days' notice to the Agent,
(i) terminate the Commitments at any time, if no Loans are outstanding at such
time, or (ii) ratably reduce from time to time by an aggregate amount of
$10,000,000 or any larger multiple of $5,000,000 the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans.

         SECTION 2.10.  Mandatory Termination or Reduction of Commitments.
         (a)  The Commitments shall terminate on the Termination Date.

         (b) On the fifth Domestic Business Day following any Asset Sale that
results in positive Excess Net Sales Proceeds, (i) the Company will deliver to
each of the Banks a certificate of the chief financial officer, the chief
accounting officer or the treasurer of the Company certifying the amount of
such Excess Net Sales Proceeds from such Asset Sale, (ii) the Commitments shall
be automatically reduced ratably by an amount equal to (a) 100% of the amount
of such Excess Net Sales Proceeds minus (b) the amount, if any, by which the
Other Credit Agreement Commitments are reduced pursuant to Section 2.10(d)(ii)
of the Other Credit Agreement as a result of such Excess Net Sales Proceeds
from such Asset Sale, and (iii) the Company shall be obligated to repay such
principal amount (together with accrued interest thereon) of each Bank's
outstanding Loans, if any, as may be necessary so that after such repayment the
aggregate outstanding principal amount of such Bank's Loans does not exceed the
amount of such Bank's Commitment as then reduced.

         SECTION 2.11.  Optional Prepayments.
         (a) The Company may, upon at least one Domestic Business Day's notice
to the Agent, prepay any Borrowing in whole at any time, or from time to time in
part in amounts aggregating $10,000,000 or any larger multiple of $1,000,000, by
paying the principal amount to be prepaid together with accrued interest thereon
to the date of prepayment; provided that no partial prepayment of a Euro-Dollar
Borrowing shall be made if after giving effect thereto the principal amount of
such Borrowing would be less than $10,000,000.  Each such optional prepayment
shall be applied to prepay ratably the Loans of the several Banks included in
such Borrowing.

         (b) Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share (if any) of such prepayment and such notice shall not
thereafter be revocable by the Company.





                                      -27-
<PAGE>   34
         SECTION 2.12.  General Provisions as to Payments.
         (a) The Company shall make each payment of principal of, and interest
on, the Loans and of fees hereunder, not later than 12:00 Noon (Houston time)
on the date when due, in Federal or other funds immediately available in
Houston, to the Agent at its address referred to in Section 9.01.  The Agent
will promptly distribute to each Bank its ratable share of each such payment
received by the Agent for the account of the Banks.  Whenever any payment of
principal of, or interest on, the Base Rate Loans or of fees shall be due on a
day which is not a Domestic Business Day, the date for payment thereof shall be
extended to the next succeeding Domestic Business Day.  Whenever any payment of
principal of, or interest on, the Euro-Dollar Loans shall be due on a day which
is not a Euro-Dollar Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Dollar Business Day unless such Euro-
Dollar Business Day falls in another calendar month, in which case the date for
payment thereof shall be the next preceding Euro-Dollar Business Day.  If the
date for any payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

         (b) Unless the Agent shall have received notice from the Company prior
to the date on which any payment is due from the Company to the Banks hereunder
that the Company will not make such payment in full, the Agent may assume that
the Company 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
Bank on such due date an amount equal to the amount then due such Bank.  If and
to the extent that the Company shall not have so made such payment, each Bank
shall repay to the Agent forthwith on demand such amount distributed to such
Bank together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Agent, at the Federal Funds Rate.

         SECTION 2.13.  Funding Losses.  If the Company makes any payment of
principal with respect to any Euro-Dollar Loan (pursuant to Article II, VI or
VIII or otherwise) on any day other than the last day of an Interest Period
applicable thereto, or the end of an applicable period fixed pursuant to the
proviso to Section 2.07(b), or if the Company fails to borrow any Euro-Dollar
Loan after notice has been given to any Bank in accordance with Section
2.04(a), or if any Conversion of any Euro-Dollar Loan occurs on any day other
than the last day of an Interest Period applicable thereto, the Company shall
reimburse each Bank within 15 days after demand for any resulting loss or
expense incurred by it (or by an existing or prospective Participant in the
related Loan), including (without limitation) any loss incurred in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin from the period after any such payment or failure to borrow; provided
that such Bank shall have delivered to the Company a certificate as to the
amount of such loss or expense, which certificate shall be conclusive in the
absence of manifest error.





                                      -28-
<PAGE>   35
         SECTION 2.14.  Computation of Interest and Fees.  Interest based on
the Base Rate hereunder shall be computed on the basis of a year of 365 days
(or 366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day).  All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

         SECTION 2.15.  Chapter 15.  In no event shall the provisions of
Article 5069, Chapter 15 of the Revised Civil Statutes of Texas (which
regulates certain revolving credit loan accounts and revolving tri-party
accounts) apply to any Loan made hereunder.

         SECTION 2.16.  Maximum Interest Rate.
         (a) Nothing contained in this Agreement or the Notes shall require the
Company to pay interest at a rate exceeding the maximum rate permitted without
penalty by applicable law.  Each provision in the Financing Documents and any
other agreement executed in connection herewith is expressly limited so that in
no event whatsoever shall the amount paid thereunder, or otherwise paid, by the
Company for the use, forbearance or detention of the money to be loaned under
this Agreement, exceed that amount of money which would cause the effective
rate of interest thereon to exceed the maximum rate of interest permitted
without penalty under applicable law, and all amounts payable under the
Financing Documents or any other agreement executed in connection herewith, or
otherwise payable in connection therewith, shall be subject to reduction so
that such amounts paid or payable for the use, forbearance or detention of
money to be loaned under this Agreement shall not exceed that amount of money
which would cause the effective rate of interest thereon to exceed the maximum
rate of interest permitted without penalty under applicable law.

         (b) If the amount of interest payable for the account of any Bank on
any interest payment date in respect of the immediately preceding interest
computation period, computed pursuant to Section 2.07, would exceed the maximum
amount permitted without penalty by applicable law to be charged by such Bank,
the amount of interest payable for its account on such interest payment date
shall be automatically reduced to such maximum permissible amount.

         (c) If the amount of interest payable for the account of any Bank in
respect of any interest computation period is reduced pursuant to clause (b) of
this Section and the amount of interest payable for its account in respect of
any subsequent interest computation period, computed pursuant to Section 2.07,
would be less than the maximum amount permitted without penalty by applicable
law to be charged by such Bank, then the amount of interest payable for its
account in respect of such subsequent interest computation period shall be
automatically increased to such maximum permissible amount; provided that at no
time shall the aggregate amount by which interest paid for the account of any
Bank has





                                      -29-
<PAGE>   36
been increased pursuant to this clause (c) exceed the aggregate amount by which
interest paid for its account has theretofore been reduced pursuant to clause
(b) of this Section.

         (d) In the event that maturity of the Loans is accelerated for any
reason, or in the event of any required or permitted prepayment of the Loans,
then such consideration that constitutes interest payable for the account of
any Bank shall never include more than the maximum amount allowed without
penalty by applicable law to be charged by such Bank and excess interest, if
any, payable for the account of such Bank pursuant to its Note, this Agreement
or otherwise shall be cancelled automatically as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited on the
Loans of such Bank (or, to the extent in excess of such Loans, refunded by such
Bank to the Company).

         (e) It is further agreed that, without limitation of the foregoing,
all calculations of the rate of interest contracted for, charged or received
for the account of any Bank under the Note held by it, under this Agreement,
under any other agreement executed in connection herewith or otherwise in
connection with the Loans or the Commitment of such Bank for the purpose of
determining whether such rate exceeds the maximum nonusurious interest rate
applicable to such Bank, shall be made, to the extent permitted by usury laws
applicable to such Bank (now or hereafter enacted), by amortizing, prorating
and spreading in equal parts during the period of the full stated terms of the
Loans evidenced by such Note all interest at any time contracted for, charged
or received by such Bank in connection therewith.

         (f) To the extent that any Bank may be subject to Texas law limiting
the amount of interest payable for its account, such Bank shall utilize the
indicated (weekly) rate ceiling from time to time in effect as provided in
Article 5069-1.04 of the Revised Civil Statutes of Texas, as amended.

         SECTION 2.17.  Taxes.

         (a) Any and all payments by the Company hereunder or under the Notes
shall be made, in accordance with Section 2.12, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges and withholdings, and all liabilities with respect thereto, excluding
(i) in the case of the Agent, each Co-Agent and each Bank, United States
federal income taxes and, without duplication, any taxes imposed on its income,
and franchise taxes imposed on it, by the jurisdiction under the laws of which
the Agent, such Co-Agent or such Bank, as the case may be, is organized or any
political subdivision thereof and (ii) in the case of each Bank, taxes imposed
on its income, and franchise taxes imposed on it, by the jurisdiction of such
Bank's Applicable Lending Office or any political subdivision thereof (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").  If the Company shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to any Bank, any Co-Agent or the Agent, (i) the sum
payable





                                      -30-
<PAGE>   37
shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.17) such Bank, such Co-Agent or the Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Company shall make such deductions and (iii) the
Company shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

    (b)  In addition, the Company agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, assessments, charges
or similar levies which arise from any payment made hereunder or under the
Notes or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement or any of the Notes (hereinafter referred to as
"Other Taxes").

    (c)  The Company will indemnify each Bank, each Co-Agent and the Agent for
the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.17) paid by such Bank, such Co-Agent or the Agent (as the case may
be) and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes
were correctly or legally asserted.  Payments under any indemnification
provided for in this Section 2.17(c) shall be made within 30 days from the date
such Bank, such Co-Agent or the Agent (as the case may be) makes written demand
therefor.

    (d)  Within 30 days after the date of any payment of Taxes, the Company
will furnish to the Agent, at its address referred to in Section 9.01, the
original or a certified copy of a receipt evidencing payment thereof.  Should
any Bank, any Co-Agent or the Agent ever receive any refund, credit or
deduction from any taxing authority to which such Bank, such Co-Agent or the
Agent, as the case may be, would not be entitled but for the payment by the
Company of Taxes as required by this Section 2.17 (it being understood that the
decision as to whether or not to claim, and if claimed, as to the amount of any
such refund, credit or deduction shall be made by such Bank, such Co-Agent or
the Agent, as the case may be, in its sole discretion), such Bank, such
Co-Agent or the Agent, as the case may be, thereupon shall repay to the Company
an amount with respect to such refund, credit or deduction equal to any net
reduction in taxes actually obtained by such Bank, such Co-Agent or the Agent,
as the case may be, and reasonably determined by such Bank, such Co-Agent or
the Agent, as the case may be, to be attributable to such refund, credit or
deduction.

    (e)  Each Bank represents that it is either (i) a corporation, association
or other entity organized under the laws of the United States or any state
thereof or (ii) entitled to complete exemption from United States withholding
tax imposed on or with respect to any payments, including fees, to be made to
it pursuant to this Agreement or the Notes.  Each Bank that is not organized
under the laws of the United States or any state thereof (a "Foreign Bank")
agrees to provide to the Company and the Agent, on or prior to the date of





                                      -31-
<PAGE>   38
this Agreement in the case of each Foreign Bank signatory hereto, and on the
date of the Assignment pursuant to which it became a Bank in the case of each
other Foreign Bank, two duly completed copies of United States Internal Revenue
Service Form 1001 or 4224, certifying in either case that such Foreign Bank is
entitled to receive payments from the Company under this Agreement and the
Notes without deduction or withholding of any United States federal income
taxes.  Each Foreign Bank which so delivers a Form 1001 or 4224 further
undertakes to deliver to each of the Company and the Agent two additional
copies of such form (or a successor form) on or before the date that such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form so delivered by it, and such amendments thereto
or extensions or renewals thereof as may be reasonably requested by the Company
or the Agent, in each case certifying that such Foreign Bank is entitled to
receive payments from the Company under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes, unless an
event (including without limitation any change in treaty, law or regulation)
has occurred prior to the date on which any such delivery would otherwise be
required which renders all such forms inapplicable or which would prevent such
Foreign Bank from duly completing and delivering any such form with respect to
it and such Foreign Bank advises the Company and the Agent that it is not
capable of receiving such payments without any deduction or withholding of
United States federal income tax.  Each Bank agrees to indemnify and hold the
Company and the Agent harmless from any United States taxes, penalties,
interest and other expenses, costs and losses incurred or payable by them as a
result of either (a) such Bank's failure to submit any form that it is required
to provide pursuant to this Section 2.17(e) or (b) the Agent's and the
Company's reliance on any such form which such Bank has provided to them, or on
the representation of such Bank made to them pursuant to this Section 2.17(e).

    (f)  If any Taxes are paid by the Company pursuant to this Section 2.17 in
respect of the Applicable Lending Office of any Bank, such Bank will, if
requested to do so by the Company, designate a different Applicable Lending
Office if such designation will avoid the need to pay, or reduce the amount of,
such Taxes and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants that:

         SECTION 4.01.  Corporate Existence and Power.  The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation, and has all corporate powers and all
material governmental licenses, authorizations, consents and approvals required
to own its assets and to carry on its business as now conducted and is duly
qualified as a foreign corporation in good standing in each jurisdiction where
the nature of its business or the ownership or leasing of its properties
requires such qualification and where the failure so to qualify could have a
material adverse effect on the business, financial position, results of
operations or prospects of the Company and its Subsidiaries, taken as a whole.
Neither the Company nor any Subsidiary or Affiliate is subject to regulation
under the Public Utility Holding Company Act of 1935, the Investment Company
Act of 1940, the Interstate Commerce Act or any other law or regulation which
limits the incurrence by the Company or any Subsidiary of Debt, including, but
not limited to, laws relating to common or contract carriers or the sale of
electricity, gas, steam, water or other public utility services.

         SECTION 4.02.  Corporate and Governmental Authorization;
Contravention.  The execution, delivery and performance by the Company of each
Financing Document to which it is shown as being a party are within the
Company's corporate powers, have been duly authorized by all necessary
corporate action, and do not contravene, or constitute a default under, any
provision of applicable law or regulation (including, without limitation,
Regulations G, T, U and X of the Board of Governors of the Federal Reserve
System) or the certificate of incorporation, by-laws or other charter documents
of the Company or of any instrument or agreement evidencing or governing Debt
or any other material agreement,





                                      -34-
<PAGE>   41
judgment, injunction, order, decree or other instrument binding upon the
Company or result in the creation or imposition of any material Lien on any
asset of the Company or any Subsidiary.  All authorizations, consents and
approvals of governmental bodies, agencies or officials required in connection
with the execution, delivery and performance by the Company of the Financing
Documents to which it is shown as being a party have been obtained and are in
full force and effect.

         SECTION 4.03.  Binding Effect.  This Agreement and each of the Notes
have been duly executed and delivered by the Company and constitute legal,
valid and binding agreements of the Company.

         SECTION 4.04.  Information.

         (a) The consolidated balance sheet of the Company and its Consolidated
Subsidiaries as of December 31, 1996 and the related consolidated statements of
operations, cash flows and common stock and other shareholders' equity for the
fiscal year then ended, reported on by Price Waterhouse LLP and set forth in
the Company's 1996 Form 10-K, a copy of which has been delivered to each of the
Banks, fairly present, in conformity with generally accepted accounting
principles, the consolidated financial position of the Company and its
Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such fiscal year.

         (b) To the best knowledge of the Company, there are no statements or
conclusions in any Engineering Report delivered pursuant hereto which are based
upon or include misleading information or fail to take into account material
information regarding the matters reported therein, it being understood that
such statements and conclusions are necessarily based upon professional
opinions, estimates and forecasts, and the Company does not warrant that such
opinions, estimates and forecasts will ultimately prove to have been accurate.

         (c) The Company's 1996 Form 10-K does not contain any untrue statement
of material fact or omit to state a material fact necessary in order to make
the statements contained therein not misleading as of the date thereof.  Except
for matters of general public knowledge with respect to the oil and gas
industry, the Company has disclosed to the Banks in writing any and all facts
which materially and adversely affect or may be reasonably expected so to
affect (to the extent the Company can now reasonably foresee) the business,
assets, operations, prospects or condition, financial or otherwise, of the
Company and its Subsidiaries or the ability of the Company to perform its
obligations under the Financing Documents.





                                      -35-
<PAGE>   42
         (d) Since December 31, 1996 there has been no material adverse change
in the business, financial position, results of operations or prospects of the
Company and its Subsidiaries, taken as a whole.

         (e) No Default exists.

         SECTION 4.05.  Litigation.  There is no action, suit or proceeding
pending against, or to the knowledge of the Company threatened against or
affecting, the Company or any of its Subsidiaries or any of their respective
properties or interests at law or in admiralty or equity, before any court or
arbitrator or any governmental body, agency or official, foreign or domestic,
in which there is a reasonable possibility of an adverse decision which could
materially adversely affect the business, financial position or results of
operations of the Company and its Subsidiaries, taken as a whole, or which in
any manner draws into question the validity of any Financing Document.

         SECTION 4.06.  Compliance with ERISA.  Each member of the ERISA Group
has fulfilled its obligations under the minimum funding standards of ERISA and
the Internal Revenue Code with respect to each Plan and is in compliance in all
material respects with the presently applicable provisions of ERISA and the
Internal Revenue Code with respect to each Plan.  No member of the ERISA Group
has (i) sought a waiver of the minimum funding standard under Section 412 of
the Internal Revenue Code in respect of any Plan, (ii) failed to make any
contribution or payment to any Plan or Multiemployer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could result in the imposition of a Lien or the posting
of a bond or other security under ERISA or the Internal Revenue Code or (iii)
incurred any liability under Title IV of ERISA other than a liability to the
PBGC for premiums under Section 4007 of ERISA.

         SECTION 4.07.  Environmental Matters.  In the ordinary course of its
business, the Company conducts an ongoing review of the effect of existing
Environmental Laws on the business, operations and properties of the Company
and the Subsidiaries, in the course of which it attempts to identify and
evaluate associated liabilities and costs (including, without limitation, any
capital or operating expenditures required for clean-up or closure of
properties presently or previously owned, any capital or operating expenditures
required to achieve or maintain compliance with environmental protection
standards imposed by law or as a condition of any license, permit or contract,
any related constraints on operating activities, including any periodic or
permanent shutdown of any facility or reduction in the level of or change in
the nature of operations conducted thereat and any actual or potential
liabilities to third parties, including employees, and any related costs and
expenses).  On the basis of this review, the Company has reasonably concluded
that existing Environmental Laws are unlikely to have a material adverse effect
on the business, financial condition, results of operations or prospects of the
Company and its Subsidiaries, taken as a whole.





                                      -36-
<PAGE>   43
         SECTION 4.08.  Subsidiaries.  All Restricted Assets are owned as of
the date of this Agreement by the Company and the Persons listed in Part B of
Schedule II hereto or, in the case of Restricted Assets sold since December 31,
1993, by Persons other than Unrestricted Subsidiaries.  Part A of Schedule II
hereto contains a true, complete and accurate list of all Unrestricted
Subsidiaries, and Part B of Schedule II hereto contains a true, complete and
accurate list of all Restricted Subsidiaries as of the date of this Agreement.

         SECTION 4.09.  Ownership of Restricted Subsidiaries. The Company or a
Restricted Subsidiary is the record and beneficial owner, free and clear of all
Liens (other than those permitted by Section 5.07), of (i) all of the issued
and outstanding capital stock (other than directors' qualifying shares and
shares beneficially owned by the Company or a Restricted Subsidiary and held by
nominees of the Company or a Restricted Subsidiary solely to satisfy
requirements of local law) and other ownership interests of each Restricted
Subsidiary (except Unimar and the Unimar Restricted Subsidiaries and any other
Restricted Subsidiary the capital stock of which is sold pursuant to a sale
permitted by Section 5.14) and (ii) except during any period during which
Unimar is an Unrestricted Subsidiary or ceases to be a Subsidiary, at least 50%
of the ownership interest in Unimar and the Unimar Restricted Subsidiaries.
Except as disclosed on Schedule VI, there are no outstanding options, warrants
or other rights to acquire any capital stock or other ownership interest of any
Restricted Subsidiary.

         SECTION 4.10.  Title to Properties.  The Company and each of the
Subsidiaries have good title, free and clear of all Liens, claims, burdens and
title defects, to all of the material assets reflected in the Company's or such
Subsidiary's books and records as being owned by them except Liens permitted by
this Agreement and claims, burdens and title defects not materially adverse in
the aggregate.

         SECTION 4.11.  Taxes and Other Obligations.  Consolidated United
States Federal income tax returns of the Company and the Subsidiaries have been
examined by the Internal Revenue Service, or the statutory period for such
examination has expired, for all years up to and including the year ended
December 31, 1992, and all assessed deficiencies resulting from such
examination have been discharged or reserved against as required by generally
accepted accounting principles.  The Company and the Subsidiaries have filed
all United States Federal, state and local income tax returns and all other
material domestic tax returns which are required to be filed by them and have
paid, or provided for the payment before the same became delinquent of, all
taxes due pursuant to such returns or pursuant to any assessment received by
the Company or any Subsidiary, other than those taxes being diligently
contested in good faith by appropriate proceedings.  The charges, accruals and
reserves on the books of the Company and the Subsidiaries in respect of taxes
are, in the opinion of the Company, adequate.  The Company and the Subsidiaries
have set up such reserves as are required by generally accepted accounting
principles for the payment of additional taxes for years which have not been
audited by the respective tax authorities.  The





                                      -37-
<PAGE>   44
Company and the Subsidiaries have paid all other material obligations when due
other than those being contested in good faith by appropriate proceedings.

         SECTION 4.12.  Regulation U.  Neither the Company  nor any Subsidiary
is engaged in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulation G) or margin stock
(within the meaning of Regulation U).  Following the application of the
proceeds of each Loan, not more than 25% of the value of the assets of the
Company, or of the Company and its Subsidiaries, which are subject to any
arrangement with the Agent or any Bank (herein or otherwise) whereby the
Company's or any Subsidiary's right or ability to sell, pledge or otherwise
dispose of assets is in any way restricted will be any such margin stock.

         SECTION 4.13.  Certain Obligations.  Neither the Company nor any
Subsidiary has any obligation to make payments on the Joint Venture Debt other
than those permitted by Section 5.17.  The only Non-Recourse Debt existing on
the date of this Agreement is the Existing Pakistan Non-Recourse Debt.

         SECTION 4.14.  United Kingdom Assets.  Substantially all of the
Restricted Assets located in the United Kingdom (including the United Kingdom
Sector of the North Sea) are directly owned by UTPL as of the date of this
Agreement.


                                   ARTICLE V

                                   COVENANTS

    Securities, (ii) owns a higher percentage of the Company's common stock or
    Voting Securities than the percentage owned by Kohlberg Kravis Roberts &
    Co. and/or non-operating investment entities it controls, and (iii) either
    (a) owns 50% or more of the Company's common stock or Voting Securities,
    (b) directly or indirectly elects or causes the election of Persons
    constituting in the aggregate a majority of the Board of Directors of the
    Company or any Restricted Subsidiary, or (c) exercises, directly or
    indirectly, by written agreement, control over the Company or any
    Restricted Subsidiary; provided that no Default or Event of Default shall
    occur under this subsection (k) until the Agent, following request by the
    Required Banks, gives notice to the Company that such an Event of Default
    is declared, and such notice may not be given after the date which is 45
    days after the Banks actually receive notice from the Company to the effect
    that the matters set forth in clauses (i), (ii) and (iii) have occurred
    (for purposes of this provision, "beneficial ownership" shall mean
    beneficial ownership within the meaning of Rule 13d-3 of the Securities and
    Exchange Commission promulgated under the Securities Exchange Act of 1934,
    as amended, and the number and percentage of securities beneficially owned
    by any Person or Persons shall be calculated in accordance with such Rule);
    or

         (l) any "Event of Default", as defined in the Other Credit Agreement,
    shall occur;

then, and in every such event, the Agent shall (i) if requested by Banks having
at least 51% in the aggregate amount of the Commitments, by notice to the
Company terminate the Commitments and, upon the giving of such notice by the
Agent, they shall thereupon terminate, and (ii) if requested by Banks holding
Notes evidencing at least 51% in aggregate principal amount of the Loans, by
notice to the Company declare the Notes (together with





                                      -51-
<PAGE>   58
accrued interest thereon) to be, and, upon the giving of such notice by the
Agent, the Notes shall thereupon become, immediately due and payable without
notice of intent to accelerate, notice of acceleration, presentment, demand,
protest or other notice of any kind, all of which are hereby waived by the
Company; provided that in the case of any of the Events of Default specified in
clause (g) or (h) above, without any notice to the Company or any other act by
the Agent or the Banks, the Commitments shall thereupon terminate and the Notes
(together with accrued interest thereon) shall become immediately due and
payable without notice of intent to accelerate, notice of acceleration,
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Company.

         SECTION 6.02.  Notice of Default.  The Agent shall give notice to the
Company under Section 6.01(c) promptly upon being requested to do so by any
Bank and shall thereupon notify all the Banks thereof.


                                  ARTICLE VII

                                   THE AGENT

         SECTION 7.01.  Appointment and Authorization.  Each Bank irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf
and to exercise such powers under the Financing Documents as are delegated to
the Agent by the terms hereof or thereof, together with all such powers as are
reasonably incidental thereto.

         SECTION 7.02.  Agent and Affiliates.  NationsBank shall have the same
rights and powers under the Financing Documents as any other Bank and may
exercise or refrain from exercising the same as though it were not the Agent,
and NationsBank and its affiliates may accept deposits from, lend money to, and
generally engage in any kind of business with the Company or any Subsidiary or
other affiliate of the Company as if it were not the Agent hereunder.

         SECTION 7.03.  Action by Agent.  The obligations of the Agent under
the Financing Documents are only those expressly set forth herein.  Without
limiting the generality of the foregoing, the Agent shall not be required to
take any action with respect to any Default, except as expressly provided in
Article VI.

         SECTION 7.04.  Consultation with Experts.  The Agent may consult with
legal counsel (who may be counsel for the Company or any Subsidiary),
independent public accountants, independent petroleum engineers and other
experts selected by it and the Agent shall not be liable for any action taken
or omitted to be taken by it in good faith in accordance with the advice of
such counsel, accountants, engineers or experts.





                                      -52-
<PAGE>   59
         SECTION 7.05.  Liability of Agent.  Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken
or not taken by it in connection herewith (i) with the consent or at the
request of the Required Banks or (ii) in the absence of its own gross
negligence or willful misconduct.  Neither the Agent nor any of its directors,
officers, agents or employees shall be responsible for or have any duty to
ascertain, inquire into or verify (i) any statement, warranty or representation
made in connection with this Agreement or any borrowing hereunder; (ii) the
performance or observance of any of the covenants or agreements of the Company
or any Subsidiary; (iii) the satisfaction of any condition specified in Article
III, except receipt of items required to be delivered to the Agent; (iv) the
validity, effectiveness or genuineness of the Financing Documents or any other
instrument or writing furnished in connection herewith; or (v) the accuracy of
any Engineering Report.  The Agent shall not incur any liability by acting in
reliance upon any notice, consent, certificate, statement, or other writing
(which may be a bank wire, telex or similar writing) believed by it to be
genuine or to be signed by the proper party or parties.

         SECTION 7.06.  Indemnification.  Each Bank shall, ratably in
accordance with its Commitment, indemnify the Agent (to the extent not
reimbursed by the Company) against any cost, expense (including counsel fees
and disbursements), claim, demand, action, loss or liability (except such as
result from the Agent's gross negligence or willful misconduct) that the Agent
may suffer or incur in connection with the Financing Documents or any action
taken or omitted by the Agent hereunder (IT BEING EXPRESSLY UNDERSTOOD AND
AGREED THAT, EXCEPT FOR SUCH NEGLIGENCE AS IS SO DETERMINED TO CONSTITUTE GROSS
NEGLIGENCE, SUCH INDEMNIFICATION DOES EXTEND TO THE CONSEQUENCES OF THE
ORDINARY NEGLIGENCE, WHETHER SOLE OR CONTRIBUTORY, OF THE AGENT).

         SECTION 7.07.  Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon the Agent or
any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

         SECTION 7.08.  Successor Agent.  The Agent may resign at any time by
giving written notice thereof to the Banks and the Company and may be removed
at any time with or without cause by the Required Banks.  Upon any such
resignation or removal, the Company shall have the right, with the consent of
the Required Banks, to appoint a successor Agent.  If no successor Agent shall
have been so appointed with the consent of the Required Banks, and shall have
accepted such appointment, within 30 days after the retiring Agent's





                                      -53-
<PAGE>   60
giving of notice of resignation or the Required Banks' removal of the retiring
Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor
Agent, which shall be a commercial bank organized or licensed under the laws of
the United States of America or of any State thereof and having a combined
capital and surplus of at least $50,000,000.  Upon the acceptance of its
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations under the Financing Documents.  After any retiring Agent's
resignation or removal hereunder as Agent, the provisions of this Article VII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent.

         SECTION 7.09.  Agent's Fees.  The Company shall pay to the Agent for
its own account fees in the amounts and at the times previously agreed upon
between the Company and the Agent.


                                  ARTICLE VIII

                            CHANGE IN CIRCUMSTANCES

         SECTION 8.01.  Basis for Determining Interest Rate Inadequate or
Unfair.  If on or prior to the first day of any Interest Period:

         (a) the Agent is advised by the Reference Banks that deposits in
    dollars (in the applicable amounts) are not being offered to the Reference
    Banks in the relevant market for such Interest Period, or

         (b) Banks having 50% or more of the aggregate amount of the
    Commitments advise the Agent that the London Interbank Offered Rate as
    determined by the Agent will not adequately and fairly reflect the cost to
    such Banks of funding their Euro-Dollar Loans for such Interest Period,

the Agent shall forthwith give notice thereof to the Company and the Banks,
whereupon until the Agent notifies the Company that the circumstances giving
rise to such suspension no longer exist, (i) the obligations of the Banks to
make Euro-Dollar Loans, or make any Conversion (other than changing Euro-Dollar
Loans into Base Rate Loans), shall be suspended, and (ii) unless the Company
notifies the Agent at least two Domestic Business Days before the date of any
Euro-Dollar Borrowing for which a Notice of Borrowing has previously been given
that it elects not to borrow on such date, such Borrowing shall instead be made
as a Base Rate Borrowing.





                                      -54-
<PAGE>   61
         SECTION 8.02.  Illegality.  If, after the date of this Agreement, the
adoption of any applicable law, rule or regulation, or any change therein, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Euro-Dollar Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful
or impossible for any Bank (or its Euro-Dollar Lending Office) to make,
maintain or fund its Euro-Dollar Loans, or make any Conversion (other than
changing Euro-Dollar Loans into Base Rate Loans), and such Bank shall so notify
the Agent, the Agent shall forthwith give notice thereof to the other Banks and
the Company, whereupon until such Bank notifies the Company and the Agent that
the circumstances giving rise to such suspension no longer exist, the
obligation of such Bank to make Euro-Dollar Loans, or make any Conversion
(other than changing Euro-Dollar Loans into Base Rate Loans), as the case may
be, shall be suspended.  Before giving any notice to the Agent pursuant to this
Section, such Bank shall designate a different Euro-Dollar Lending Office if
such designation will avoid the need for giving such notice and will not, in
the judgment of such Bank, be otherwise disadvantageous to such Bank.  If such
Bank shall determine that it may not lawfully continue to maintain and fund any
of its outstanding Euro-Dollar Loans to maturity and shall so specify in such
notice, each such Euro-Dollar Loan shall be immediately and automatically
Converted into a Base Rate Loan (on which interest and principal shall be
payable contemporaneously with the related Euro-Dollar Loans of the other
Banks).

         SECTION 8.03.  Increased Cost and Reduced Return.  (a) If after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change therein, or any change in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Bank (or its
Applicable Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency:

         (i) shall subject any Bank (or its Applicable Lending Office) to any
    tax, duty or other charge with respect to its Euro-Dollar Loans, its Note
    or its obligation to make Euro-Dollar Loans, or shall change the basis of
    taxation of payments to any Bank (or its Applicable Lending Office) of the
    principal of or interest on its Euro-Dollar Loans or any other amounts due
    under this Agreement in respect of its Euro-Dollar Loans or its obligation
    to make Euro-Dollar Loans (except for changes in the rate of tax on the
    overall net income of such Bank or its Applicable Lending Office imposed by
    the jurisdiction in which such Bank's principal executive office or
    Applicable Lending Office is located); or





                                      -55-
<PAGE>   62
         (ii)    shall impose, modify or deem applicable any reserve, special
    deposit or similar requirement (including, without limitation, any such
    requirement imposed by the Board of Governors of the Federal Reserve System
    against assets of, deposits with or for the account of, or credit extended
    by, any Bank (or its Applicable Lending Office) or on the United States
    market for certificates of deposit or the London interbank market any other
    condition affecting its Euro-Dollar Loans, its Note or its obligation to
    make Euro-Dollar Loans;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan or
making any Conversion (other than changing Euro-Dollar Loans into Base Rate
Loans), or to reduce the amount of any sum received or receivable by such Bank
(or its Applicable Lending Office) under this Agreement or under its Note with
respect thereto, by an amount deemed by such Bank to be material, then, within
15 days after demand by such Bank (with a copy to the Agent), the Company shall
pay to such Bank such additional amount or amounts as will compensate such Bank
for such increased cost or reduction; provided that the Company shall not be
obligated to compensate any Bank for any such reduction attributable to a
period (i) more than 90 days prior to the giving of notice by such Bank to the
Company of its intention to seek compensation under this subsection (a) or (ii)
more than six months prior to the making of demand by such Bank for payment
thereof in accordance herewith.

         (b) If any Bank shall have determined that the adoption of any
applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on capital of such Bank (or its Parent) as a
consequence of such Bank's obligations hereunder to a level below that which
such Bank (or its Parent) could have achieved but for such adoption, change,
request or directive (taking into consideration its policies with respect to
capital adequacy) by an amount deemed by such Bank to be material, then from
time to time, within 15 days after demand by such Bank (with a copy to the
Agent), the Company shall pay to such Bank such additional amount or amounts as
will compensate such Bank (or its Parent) for such reduction; provided that the
Company shall not be obligated to compensate any Bank for any such reduction
attributable to a period (i) more than 90 days prior to the giving of notice by
such Bank to the Company of its intention to seek compensation under this
subsection (b) or (ii) more than six months prior to the making of demand by
such Bank for payment thereof in accordance therewith.

         (c) Each Bank will promptly notify the Company and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such





                                      -56-
<PAGE>   63
Bank to compensation pursuant to this Section and will designate a different
Applicable Lending Office if such designation will avoid the need for, or
reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank.  A certificate of any Bank
claiming compensation under this Section and setting forth the additional
amount or amounts to be paid to it hereunder shall be conclusive in the absence
of manifest error.  In determining such amount, such Bank may use any
reasonable averaging and attribution methods.

         SECTION 8.04.  Base Rate Loans Substituted for Affected Euro-Dollar
Loans.  If (i) the obligation of any Bank to make Euro-Dollar Loans to the
Company has been suspended pursuant to Section 8.02 or (ii) any Bank has
demanded compensation under Section 8.03(a) and the Company shall, by at least
five Euro-Dollar Business Days' prior notice to such Bank through the Agent,
have elected that the provisions of this Section shall apply to such Bank,
then, unless and until such Bank notifies the Company that the circumstances
giving rise to such suspension or demand for compensation no longer apply:

         (a) all Loans to the Company which would otherwise be made by such
    Bank as, or be Converted by such Bank as or into, Euro-Dollar Loans shall
    instead be made as, or Converted into, Base Rate Loans (on which interest
    and principal shall be payable contemporaneously with the related Euro-
    Dollar Loans of the other Banks), and

         (b) after each of its Euro-Dollar Loans to the Company has been
    repaid, all payments of principal which would otherwise be applied to repay
    such Euro-Dollar Loans shall be applied to repay its Base Rate Loans
    instead.

         SECTION 8.05.  Substitution of Bank.  If (i) the obligation of any
Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.02,
(ii) any Bank has demanded compensation under Section 8.03 or payment of Taxes
or Other Taxes under Section 2.17, or (iii) after satisfaction of all
applicable conditions precedent, any Bank fails to fund when due any Loan it is
obligated to fund under this Agreement, the Company shall have the right, with
the assistance of the Agent, to seek a mutually satisfactory substitute bank or
banks (which may be one or more of the Banks) to purchase the Notes and assume
the Commitment of such Bank (any such Bank is herein called an "Affected
Bank").  Each Affected Bank agrees to sell, without recourse, all of its
Commitment, its interest in this Agreement and its Note to any such bank for an
amount equal to the sum of the outstanding unpaid principal of and accrued
interest on the Loans of such Affected Bank and all commitment fees and other
fees and amounts due such Affected Bank hereunder, calculated, in each case, to
the date such Commitment, interest in this Agreement and Note are purchased.

                                 MISCELLANEOUS

         SECTION 9.01.  Notices.  All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission or similar writing) and shall be given to such
party: (x) in the case of the Company or the Agent, at its address or telex
number set forth on the signature pages hereof, (y) in the case of any Bank, at
its address or telex number set forth in its Administrative Questionnaire or
(z) in the case of any party, such other address or telex number as such party
may hereafter specify for the purpose by notice to the Agent and the Company.
Each such notice, request or other communication shall be effective (i) if
given by telex, when such telex is transmitted to the telex number specified in
this Section and the appropriate answer-back is received, (ii) if given by
mail, 72 hours after such communication is deposited in the mails with first
class postage prepaid, addressed as aforesaid, (iii) if given by facsimile
transmission, when such facsimile is transmitted and accompanied by a telephone
call to the party receiving such transmission or (iv) if given by any other
means, when delivered at the address specified in this Section; provided that
notices to the Agent shall not be effective until received.

         SECTION 9.02.  No Waivers.  No failure or delay by the Agent or any
Bank in exercising any right, power or privilege under any Financing Document
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege.  The rights and remedies provided in the
Financing Documents shall be cumulative and not exclusive of any rights or
remedies provided by law.

         SECTION 9.03.  Expenses; Indemnification.  (a) The Company shall pay
(i) all reasonable documented out-of-pocket costs and expenses of the Agent and
the Arranger incurred in connection with the syndication of this Agreement or
the preparation of the Financing Documents, any waiver or consent thereunder or
any amendment thereof or any Default or alleged Default hereunder and (ii) if
an Event of Default occurs, all reasonable out-of-pocket costs and expenses
incurred by the Agent or incurred by any Bank, including fees and disbursements
of counsel, in connection with such Event of Default and collection and other
enforcement proceedings resulting therefrom.

         (b) The Company agrees to indemnify the Agent, each Co-Agent, the
Arranger and each Bank and hold the Agent, each Co-Agent, the Arranger and each
Bank harmless from and against any and all liabilities, losses, damages, costs
and expenses of any kind (including, without limitation, the reasonable fees
and disbursements of counsel for the Agent, any Co-Agent, the Arranger or any
Bank in connection with any investigative, administrative or judicial
proceedings, whether or not the Agent, such Co-Agent, the





                                      -58-
<PAGE>   65
Arranger or such Bank, as the case may be, shall be designated a party thereto)
which may be incurred by the Agent, any Co-Agent, the Arranger or any Bank,
relating to or arising out of this Agreement or any actual or proposed use of
proceeds of Loans hereunder, including specifically, without limitation, all
liabilities, losses, damages, costs and expenses arising out of a violation of
any Environmental Law; provided that neither the Agent nor any Co-Agent nor the
Arranger nor any Bank shall have the right to be indemnified hereunder for its
own gross negligence or willful misconduct as determined by a court of
competent jurisdiction (IT BEING EXPRESSLY UNDERSTOOD AND AGREED THAT, EXCEPT
FOR SUCH NEGLIGENCE AS IS SO DETERMINED TO CONSTITUTE GROSS NEGLIGENCE, SUCH
INDEMNIFICATION DOES EXTEND TO THE CONSEQUENCES OF THE ORDINARY NEGLIGENCE,
WHETHER SOLE OR CONTRIBUTORY, OF THE INDEMNITEE).

         (c) Within a reasonable period of time after any Person entitled to
indemnification under Section 9.03(b) (an "Indemnified Person") receives actual
notice of the assertion of any claim or the commencement of any action, or any
threatened claim or action, covered by Section 9.03(b), such Indemnified Person
shall, if indemnification with respect thereof is to be sought from the Company
under Section 9.03(b), notify the Company in writing of such claim or action;
provided that the failure to so notify the Company shall not relieve the
Company from any liability which the Company may have to the Indemnified Person
under Section 9.03(b) unless the obligations of the Company under Section
9.03(b) have been significantly increased as a result of such failure.  The
Company and such Indemnified Person shall cooperate in the defense of any such
claim or action and shall take those actions reasonably within their power to
take which are necessary to preserve any legal defenses to such matters.  If
any such claim or action shall be brought or threatened against an Indemnified
Person, so long as no Event of Default exists, the Company shall be entitled to
participate in the defense thereof, and, with the consent of such Indemnified
Person, to assume the defense thereof with counsel reasonably satisfactory to
the Indemnified Person.  Notwithstanding any provision hereof to the contrary,
no consent order or settlement shall be entered into in any such claim or
action unless both the Company and such Indemnified Person have given their
prior written consent thereto; provided that such consent of the Company shall
not be required if any Event of Default exists.

         (d) All obligations of the Company to indemnify or otherwise to make
payments to the Agent, any Co-Agent, the Arranger or any Bank provided in this
Agreement shall survive any termination of the Commitments and the repayment of
the Loans.

         SECTION 9.04.  Sharing of Set-Offs, Etc.  Each Bank agrees that if it
shall, by exercising any right of set-off or counterclaim or otherwise, receive
payment of a proportion of the aggregate amount of principal and interest due
with respect to any Note held by it which is greater than the proportion
received by any other Bank in respect of the aggregate amount of principal and
interest due with respect to any Note held by such other





                                      -59-
<PAGE>   66
Bank, the Bank receiving such proportionately greater payment shall purchase
such participations in the Notes held by the other Banks, and such other
adjustments shall be made, as may be required so that all such payments of
principal and interest with respect to the Notes held by the Banks shall be
shared by the Banks pro rata; provided that nothing in this Section shall
impair the right of any Bank to exercise any right of set-off or counterclaim
it may have and to apply the amount subject to such exercise to the payment of
indebtedness of the Company other than its indebtedness under the Notes.  The
Company agrees, to the fullest extent it may effectively do so under applicable
law, that any holder of a participation in a Note, whether or not acquired
pursuant to the foregoing arrangements, may exercise rights of set-off or
counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of the Company in the
amount of such participation.

         SECTION 9.05.  Amendments and Waivers.  Any provision of this
Agreement or the Notes may be amended or waived, if, but only if, such
amendment or waiver is in writing and is signed by the Company and the Required
Banks (and, if the rights or duties of the Agent are affected thereby, by the
Agent); provided that no such amendment or waiver shall, unless signed by all
the Banks, (i) increase or decrease the Commitment of any Bank or subject any
Bank to any additional obligation, (ii) reduce the principal of or rate of
interest on any Loan or any fees hereunder, (iii) postpone the date fixed for
any payment of principal of or interest on any Loan or any fees hereunder or
for any reduction or termination of any Commitment, or (iv) change the
percentage of the Commitments or of the aggregate unpaid principal amount of
the Notes, or the number of Banks, which shall be required for the Banks or any
of them to take any action under this Section or any other provision of this
Agreement.

         SECTION 9.06.  Successors and Assigns.        

         (a) The provisions of this Agreement shall be binding upon and inure 
to the benefit of the parties hereto and their respective successors and
assigns, except that the Company may not assign or otherwise transfer any of its
rights under this Agreement without the prior written consent of all Banks.

         (b) Any Bank may at any time and from time to time grant to one or
more banks or other institutions (each a "Participant") participating interests
in its Commitment or any or all of its Loans.  In the event of any such grant
by a Bank of a participating interest to a Participant, whether or not upon
notice to the Company and the Agent, such Bank shall remain responsible for the
performance of its obligations hereunder, and the Company and the Agent shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under this Agreement.  Any agreement pursuant to
which any Bank may grant such a participating interest shall provide that such
Bank shall retain the sole right and responsibility to enforce the obligations
of the Company hereunder including, without limitation, the right to approve
any amendment, modification or waiver of any





                                      -60-
<PAGE>   67
provision of this Agreement; provided that such participation agreement may
provide that such Bank will not agree to any modification, amendment or waiver
of this Agreement described in clause (i), (ii) or (iii) of Section 9.05
without the consent of the Participant.  The Company agrees that each
Participant shall, to the extent provided in its participation agreement, be
entitled to the benefits of Article VIII with respect to its participating
interest.  An assignment or other transfer which is not permitted by subsection
(c) or (d) below shall be given effect for purposes of this Agreement only to
the extent of a participating interest granted in accordance with this
subsection (b).

         (c) Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") a proportionate part of all of its rights and
obligations under this Agreement and the Notes in an amount which, when added
to the amount of the rights and obligations under the Other Credit Agreement
contemporaneously assigned by such transferor Bank to such Assignee pursuant to
the second proviso to the first sentence of Section 9.06(c) of the Other Credit
Agreement, equals $10,000,000 or more, and such Assignee shall assume such
rights and obligations under this Agreement and the Notes, pursuant to an
Assignment executed by such Assignee and such transferor Bank, with (and
subject to) the subscribed consent of the Company and the Agent (which such
consents shall not be unreasonably withheld); provided that if an Assignee is
an affiliate of such transferor Bank or is another Bank, no such consent of the
Company shall be required; provided further that each such assignment shall be
of a constant, and not a varying, percentage of all rights and obligations
under this Agreement and the Notes, and the same constant percentage of all
rights and obligations of such transferor Bank under the Other Credit Agreement
and the notes thereunder shall be contemporaneously assigned by such transferor
Bank to such Assignee pursuant to Section 9.06(c) of the Other Credit
Agreement.  Upon execution and delivery of such instrument (and delivery to the
Agent of an Administrative Questionnaire with respect to such Assignee, if such
Assignee has not already done so) and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such
transferor Bank and such Assignee, such Assignee shall be a Bank party to this
Agreement and shall have all the rights and obligations of a Bank with a
Commitment as set forth in such instrument of assumption, and the transferor
Bank shall be released from its obligations hereunder to a corresponding
extent, and no further consent or action by any party shall be required.  Upon
the consummation of any assignment pursuant to this subsection (c), the
transferor Bank, the Agent and the Company shall make appropriate arrangements
so that, if required, a new Note is issued to the Assignee.  In connection with
any such assignment, the transferor Bank shall pay to the Agent for its account
an administrative fee for processing such assignment in the amount of $2,500
less any administrative processing fee paid to the Agent on the same date under
Section 9.06(c) of the Other Credit Agreement as a result of the
contemporaneous assignment to such Assignee by such transferor Bank under the
Other Credit Agreement pursuant to the second proviso to the first sentence of
this Section 9.06(c).  If the Assignee is not incorporated under the laws of
the United States of America or a state thereof, it shall, prior to the first
date on which





                                      -61-
<PAGE>   68
interest or fees are payable hereunder for its account, deliver to the Company
and the Agent certification as to exemption from deduction or withholding of
any United States federal income taxes in accordance with Section 2.17.
Notwithstanding the first sentence of this subsection (c), a Bank may not make
an assignment pursuant to this subsection (c) if after giving effect thereto
such Bank would hold less than 1.5% (or until March 1, 1999, 3% in the case of
NationsBank, Bank of America National Trust and Savings Association and Union
Bank of Switzerland, Houston Agency) of the Commitments (for this purpose such
Bank shall be deemed to hold any participating interests granted by such Bank
pursuant to subsection (b) above and any rights assigned pursuant to subsection
(d) below).

         (d) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note to a Federal Reserve Bank.  No such
assignment shall release the transferor Bank from its obligations hereunder.

         (e) No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 than such
Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Company's prior written
consent or by reason of the provisions of Section 8.02 or 8.03 requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

         SECTION 9.07.  Collateral.  Each of the Banks represents to each Agent
and each of the other Banks that it in good faith is not relying upon any
margin stock (as defined in Regulation G) or any margin stock (as defined in
Regulation U) as collateral in the extension or maintenance of the credit
provided for in this Agreement.

         SECTION 9.08.  Texas Law.  This Agreement and each Note shall be
construed in accordance with and governed by the law of the State of Texas.

IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE
STATE OF TEXAS AND OF ANY FEDERAL COURT LOCATED IN SUCH STATE OVER IT IN
CONNECTION WITH ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY
FINANCING DOCUMENT AND, TO THE FULLEST EXTENT PERMITTED BY LAW, FURTHER AGREES
(AND SHALL NOT CONTEST) THAT THE PROPER VENUE FOR FILING AND MAINTAINING ANY
SUCH ACTION OR PROCEEDING SHALL BE IN THE STATE OF TEXAS.  IN ANY SUCH ACTION
OR PROCEEDING, THE COMPANY WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR
OTHER PROCESS OR NOTICE AND AGREES THAT SERVICE BY FIRST CLASS MAIL, RETURN
RECEIPT REQUESTED, TO

THE COMPANY AT ITS ADDRESS FOR NOTICES HEREUNDER, OR ANY FORM OF SERVICE
PROVIDED FOR IN THE TEXAS CIVIL PRACTICE AND REMEDIES CODE THEN IN EFFECT SHALL

         SECTION 9.10.  Counterparts.  This Agreement may be signed in any
number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.

JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR
THE TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION 9.12.  COMPLETE AGREEMENT.  THIS WRITTEN CREDIT AGREEMENT AND
THE OTHER FINANCING 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 9.13.  Liability of Co-Agents and Arranger.  Neither the
Arranger nor either Co-Agent, in its capacity as Co-Agent hereunder, shall have
any duty or responsibility hereunder.

         SECTION 9.14.  Termination of 1996 Short-Term Commitments.  Each of
the parties hereto agrees that all "Commitments" (as defined in the
$100,000,000 Credit Agreement dated as of March 29, 1996 among the Company,
NationsBank, as agent and the co-agent and lenders parties thereto) are hereby
terminated effective as of the close of business on March 10, 1997 (and the
fees under Section 2.08(a) of such Credit Agreement shall accrue through such
date), and the Company has no further right to borrow thereunder.  The Company
represents and warrants that all principal, interest and fees owed thereunder
have been paid in full.

                            (ii)  during the Availability Period at any time on

the time of calculation) of the Source of Debt Service reasonably anticipated
to be payable from the time of calculation to the Final Maturity Date, plus (y)
the amount held in the Reserve Account at the time of calculation, divided by
(2) the aggregate outstanding principal amount of the Advances, in each case at
the time of calculation, multiplied by (b) 100.

The assumptions necessary for calculating the Debt Coverage Ratio are set forth
in Schedule 3 hereto.  These assumptions shall remain in effect for purposes of

assumptions have been mutually agreed by the Borrower and the Agent, as
provided herein or in the definition of Assumed Interest Rate, determined as
provided in the definition of Assumed Interest Rate or specified by a Selected
Qualified Bank as provided herein or in the definition of Assumed Interest
Rate.  The Borrower or the Agent may at any time (but not more than once each
calendar quarter) request a reconsideration of such assumptions, whereupon the
Borrower and the Agent shall negotiate in good faith to reach agreement on the
assumptions described below, used in calculating the Debt Coverage Ratio which
are acceptable to the Borrower and the Agent.  The assumptions to be negotiated
in good faith are, in addition to the Assumed Interest Rate as provided
<PAGE>   13
                                                                               8




in the definition thereof, those with respect to the realized export prices of
all classifications of Indonesian crude oil and the U.S. Consumer Price Index,
in each case as such realized export prices and Consumer Price Index are used
for determining the LNG sales price in the relevant LNG Sales Contract.  If the
Borrower and the Agent cannot reach agreement on such assumptions (other than
the Assumed Interest Rate) within 10 Business Days (or such longer period as
they may agree) following a request by one to the other for such negotiations,

conditions set forth in this Agreement, during the Availability Period each
Lender severally, and not jointly or jointly and severally, agrees to make
Advances to the Borrower in Dollars through its Lending Office.  The Advances
shall be made by each Lender on the Borrowing Dates and in the amounts provided

                          (a)     Subject to the limitations provided in
Section 2.1 hereof, the Borrower shall have the right to elect to borrow from
the Lenders on each Borrowing Date amounts (rounded upward or downward, so that

provided for in the Drawdown Schedule as the same may be revised from time to

                          (b)     Subject to the limitations provided in
Section 2.1 hereof, the Borrower shall have the right to elect to borrow from
the Lenders, in addition to the amounts permitted by Section 2.2(a) hereof, the
following amounts ("Borrowed Amounts"):

                                     (i)   on each Borrowing Date occurring
         during the Availability Period and prior to the first day of the
         Amortization Period, an amount to be used to pay, and equal in amount
         to the sum of the amount of interest, fees, expenses, taxes and other
         amounts payable by the Borrower pursuant to Sections 2.3, 2.6, 2.7,
         3.3, 3.4(b), 6.6 and 10.6 hereof which are due on such Borrowing Date,
         which amounts shall be used only to pay the amounts referred to
         therein, and

                                     (ii)  on the Reserve Account Borrowing
         Date, an amount (the "Reserve Account Borrowed Amount") to be paid to
         the Reserve Account, which amount shall not exceed the lesser of (A)
         the Anticipated Loan Amounts (as defined in the Trust Agreement) as of
         such Borrowing Date as reasonably estimated and reflected in the
         relevant Notice of Borrowing, and determined without giving effect to
         any amount then held in the Reserve Account, and (B) the amount of
         Commitments undrawn immediately before such Borrowing Date, less the
         sum of any Borrowed Amounts borrowed on such Borrowing Date pursuant
         to Section 2.2(b)(i) and 100 percent of the costs estimated to be
         required for (x) the completion and final acceptance of the Additional

         Project) pursuant to the Development Plan and the EPC Contract and (y)
         the completion of the Debottlenecking Project pursuant to the
         Development Plan, as set forth in the report referred to in Section
         5.3(c) hereof.

The amount of any Borrowings made pursuant to this Section 2.2(b) shall be

interest as specified in Sections 2.3, 2.4, 2.5 and 2.6 hereof.

Borrowings under Section 2.2(a), separately identifying Borrowings relating to
the different costs related to Train H as provided therein), anticipated to be
requested during the Availability Period.  The Borrower shall update

                                                                              22




the Drawdown Schedule from time to time, but in any event not less frequently
than approximately every six months following the initial Borrowing Date and
shall immediately provide such updated Drawdown Schedule to the Agent.  If at
any time it is anticipated that a Borrowing to be made on a Borrowing Date will
be in an amount greater than 110% of the amount indicated for such Borrowing on
the then current Drawdown Schedule or pursuant to any previous notice given
pursuant to this sentence, the Borrower shall use all reasonable efforts (but
shall not be liable for failure) to deliver notice thereof, which shall include
the then anticipated amount of such Borrowing, to the Agent as soon as
practicable in order to facilitate the Lenders' funding arrangements with
respect to such Borrowing.

                          (d)     (i)      With respect to each Borrowing, the
         Borrower shall give to the Agent not later than noon, New York time,
         on or prior to the eighth Business Day preceding such Borrowing Date,
         a Notice of Borrowing, in writing, which shall specify the amount of
         such Borrowing and the account or accounts to which such Borrowing
         shall be made available, each of which shall be the proper account for
         the deposit of each portion of such Borrowing as provided in the Trust
         Agreement.  In addition, the Borrower shall give a copy of the Notice
         of Borrowing to the Finance Company, on which the Finance Company may
         rely as if addressed to it as a Lender hereunder; provided that for
         such purpose the amount of the Advance to be made by it shall equal
         the percentage of the amount of such Borrowing equal to the
         outstanding Commitment of the Finance Company divided by the
         outstanding Commitments of all Lenders; and provided, further, that
         the copy of the notice to the Finance Company shall be deemed timely
         if received by the Finance Company not later than noon, Tokyo time, on
         the date seven Business Days preceding such Borrowing Date.

                                  (ii)     The amount to be drawn down on any
         Borrowing Date shall be $5,000,000.00 or any larger integral multiple
         of $1,000,000.00, except in the case of the final Borrowing Date, in
         which case the amount to be drawn down shall be any amount of the
         undrawn Commitments specified by the Borrower; provided that the
         aggregate amount to be drawn down on any Borrowing Date shall in no
         event exceed the aggregate amount of then outstanding Commitments.
         The total amount to be drawn down on any Borrowing Date shall be
         apportioned by the Agent on a pro rata basis among the outstanding
         Commitments of the Lenders.

                                  (iii)    A Notice of Borrowing, once it has
         been received by the Agent or a copy of it has been received by the
         Finance Company, shall not be revocable by the Borrower.

                                                                              23




                                  (e)      Upon receipt of a Notice of
         Borrowing, the Agent shall forthwith notify each Lender (including the
         Finance Company) of the Borrowing Date identified therein.  Before
         11:00 a.m., New York time, on such Borrowing Date each Lender will
         make available in Dollars the amount of such Lender's Advance to be
         made on such Borrowing Date in same day settlement funds by credit of
         Federal or other immediately available funds satisfactory to the Agent
         to the account of the Agent (account no. 323-5-09967) at The Chase
         Manhattan Bank, Administrative Agent, Loan & Agency Services, located
         at 1 Chase Manhattan Plaza, 8th Floor, New York, New York 10081,
         U.S.A. for the account of the Borrower or at such other office or bank
         in New York, New York or elsewhere as the Agent may from time to time
         designate by telex (to be confirmed by letter) to the Lenders (other
         than the Finance Company) and by facsimile (to be confirmed by letter)
         to the Finance Company.  Upon and subject to the terms and conditions
         of this Agreement, before 1:00 p.m., New York time, on such Borrowing
         Date the Agent shall make available to the Borrower to the account or
         accounts in New York City as shall have been specified by the Borrower
         in such Notice of Borrowing on such Borrowing Date the funds made
         available to the Agent pursuant to the next preceding sentence in the
         same funds as received by the Agent.

                                  (f)      The failure of a Lender to make an
         Advance to be made by it on the date specified therefor shall not
         relieve any other Lender of its obligation to make its Advance
         hereunder on such date, and no Lender shall be responsible for the
         failure of any other Lender to make an Advance to be made by such
         other Lender on the date specified therefor.  Unless the Agent shall
         have been notified by a Lender one Business Day prior to a Borrowing
         Date (which notice shall be effective only upon receipt) that such
         Lender does not intend to make available to it such Lender's Advance
         to be made on such date, the Agent may (but shall have no obligation
         to) assume that such Lender has made such Lender's Advance available
         to it on such date, and the Agent may, in reliance upon such
         assumption, make available (but shall have no obligation to make
         available) to the Borrower a corresponding amount.  If the Lender's
         Advance is not in fact made available to the Agent by such Lender, the
         Agent shall be entitled to recover such amount either on demand from
         such Lender or on demand and in accordance with the provisions of
         Section 3.10 hereof from the Borrower together with interest thereon
         at a rate per annum representing the interest cost to the Agent (as
         determined by the Agent using reasonable efforts to minimize such
         cost) of funding the amount in question until reimbursement thereof to
         the Agent; provided that to the extent such amount is recovered from
         the Borrower, interest paid thereon by the Borrower shall not exceed
         the rate or rates per annum then applicable to the Advances.

                 2.3      Interest.  The Borrower shall pay interest on the
unpaid principal amount of all Advances outstanding from time to time at the
applicable interest rates determined in accordance with Section 2.4 or 2.5
hereof, as the case may be, with respect to each Interest Period.  Such
interest payable with respect to each Interest Period shall be paid on the
Interest Payment Date at the end of such Interest Period.

                                                                              24




Interest on the Advances shall be calculated from and including the relevant
Borrowing Date up to but not including the date of actual receipt of repayment
and shall be computed on the basis of a year of 360 days, and shall be payable
for the actual number of days elapsed.

                 2.4      Determination of Interest Rates.

                          (a)     On the LIBOR Business Day (the "Reference
Date") that is two LIBOR Business Days prior to the commencement of each
Interest Period, the Agent shall fix the interest rate for the Advances and any
Deferred Portion to be outstanding with respect to and during such Interest
Period, in each case at the rate per annum equal to the sum of the Applicable
Margin plus the London Interbank Offered Rate (the London Interbank Offered
Rate is referred to as "LIBOR").  LIBOR for each such Interest Period shall be
the rate for deposits in Dollars which appears on page 3750 of the Telerate
screen (or such other page as may replace that page on the Telerate screen for
the purpose of displaying London interbank Dollar deposit rates of leading
reference banks and as may be selected by the Agent) as of approximately 11:00
a.m., London time, on the Reference Date for a period equal to such Interest
Period, as determined by the Agent.  If such an offered rate is not available
on the relevant page of the Telerate screen or if the Telerate screen is
unavailable, or if an offered rate is not quoted on the Telerate screen for
Dollars or for the period required at or about 11:00 a.m., London time, on the
Reference Date, LIBOR for each such Interest Period shall be the arithmetic
mean (rounded upward, if necessary, to the nearest 1/16 of 1%) of the rates
which are quoted at or about 11:00 a.m., London time, on the Reference Date for
a period equal to such Interest Period, on such Business Day on the "LIBO" page
of the Reuters Monitor Money Rates Service (or such other page of the Reuters
Monitor Money Rates Service as may replace such LIBO page for the purpose of
displaying London interbank Dollar offered rates of leading reference banks and
as may be selected by the Agent).  So long as at least two quotations are
available on the "LIBO" page for a period equal to such Interest Period, LIBOR
for such Interest Period shall be determined in accordance with the preceding
sentence on the basis of the offered quotations as quoted.  The determinations
of the Agent shall be conclusive in the absence of manifest error.

                          (b)     If pursuant to Section 2.4(a) hereof the use
of the "LIBO" page is required, and the "LIBO" page does not at the appointed
time with respect to any Interest Period display at least two offered
quotations, LIBOR for such Interest Period shall be the average (rounded
upward, if necessary, to the nearest 1/16 of 1%) of the respective rates per
annum at which deposits in Dollars are offered to each of the Reference Banks
in the London interbank market as of approximately 11:00 a.m., London time, on
the Reference Date for a period comparable to the Interest Period and in an
amount of $50,000,000.00.  The determination of the Agent shall be conclusive
in the absence of manifest error and shall be made on the above basis as soon
as
<PAGE>   30
                                                                              25




practicable thereafter, New York time.  If for any reason no quotation is
furnished by one or more of the Reference Banks to the Agent, the Agent shall
determine such interest rate on the basis of the quotations furnished by the
remaining Reference Banks.

                 2.5      Alternative Interest Rates; Voluntary Prepayment.
If, on any date on which an interest rate is to be fixed pursuant to Section
2.4 hereof, (i) none of the Reference Banks is able to furnish a quotation to
the Agent for purposes of determining an interest rate pursuant to Section
2.4(b) hereof or (ii) for purposes of determining an interest rate pursuant to
Section 2.4(b) hereof the Agent is notified by all of the Reference Banks that
deposits in Dollars in an amount of $50,000,000.00 are not being offered to the
Reference Banks in the London interbank market or (iii) the Agent is notified
by Notice Lenders (as defined in the last sentence of this Section 2.5) that
the rate or rates for Dollar deposits displayed on the Telerate screen or the
"LIBO" page (as applicable pursuant to Section 2.4(a) hereof) or, in the event
that LIBOR for such Interest Period is being determined pursuant to Section
2.4(b) hereof, the rates at which Dollar deposits are being offered to the
Reference Banks in the London interbank market plus all costs associated with
reserves, special deposits, deposit insurance or similar requirements to be
maintained or paid in accordance with the regulations or other requirements of
the Federal Reserve System, the Federal Deposit Insurance Corporation or any
other department, agency or instrumentality of the United States of America or
any state thereof (collectively, "Reserves") in effect on the date of this
Agreement do not adequately reflect the cost to the relevant Lenders of making
or maintaining for the next succeeding Interest Period their respective
Advances or any Deferred Portion thereof, then the Agent shall promptly give
notice of such fact to the Borrower and the relevant Lenders.  During the 30
days next succeeding the giving of such notice, the Borrower and the relevant
Lenders shall negotiate in good faith in order to arrive at a mutually
satisfactory interest rate which shall be applicable to such Advances and
Deferred Portions to be outstanding during such Interest Period instead of
LIBOR.  If within such 30-day period the Borrower and the relevant Lenders
agree in writing upon an alternative interest rate, such rate shall be
substituted for LIBOR and shall be effective with respect to the relevant
amounts from the commencement of such Interest Period.  The Borrower shall pay
to the relevant Lenders interest on such Advances and Deferred Portions
calculated based upon such alternative interest rate plus the Applicable Margin
during such Interest Period.  If the Borrower and the relevant Lenders fail to
agree upon such an alternative interest rate within such 30-day period, the
interest rate during such Interest Period, applicable to each relevant Lender's
Advance and each relevant Lender's Deferred Portion and effective from the
commencement of such Interest Period shall be such rate as such Lender shall
determine (in a certificate delivered by such Lender to the Agent setting forth
the basis of the computation of such rate, which certificate shall in the
absence of manifest error be conclusive and binding on the Borrower) to be
necessary to compensate each such Lender for its actual out-of-pocket cost, and
costs associated with such Reserves (determined in good faith using reasonable
efforts to minimize the interest cost to the

                                                                              26




Borrower, rounded upward, if necessary, to the nearest 1/16 of 1% and
disregarding for such purposes all costs of Reserves in effect on the date of
this Agreement), as of the commencement of such Interest Period, of funds for
such Interest Period in an amount equal to the aggregate principal amount of
each relevant Lender's Advances and each relevant Lender's Deferred Portion to
which such Interest Period relates plus the Applicable Margin.  The Agent shall
notify the Borrower of such determination as promptly as practicable.  After
the Agent shall have notified the Borrower of such determination and during the
period such interest rate continues to be applicable, the Borrower may elect to
prepay any one or more of the relevant Notes or the Deferred Portion of the
relevant Notes without premium or penalty (except as provided in Section 2.6(b)
hereof) in accordance with the provisions of Section 3.6 hereof.  For purposes
of this Section 2.5, "Notice Lenders" means at any time Lenders holding in
excess of 15% of the aggregate unpaid principal amount of the Advances, or if
no such Advances are at the time outstanding, Lenders having in excess of 15%
of the aggregate amount of the Commitments.

                 2.6      Interest Rate on Overdue Amounts; Other Indemnities.

                          (a)     The Borrower shall pay interest on overdue
principal of any Note and, so far as may be lawful, on any other overdue amount
owing pursuant to this Agreement, the Notes and the Letter Agreement, from and
including the date the payment thereof was due to, but not including, the day
of actual payment, at a rate per annum which shall be (i) with respect to the
period ending on the fourth anniversary of the initial Borrowing Date
hereunder, 2.10%, and (ii) thereafter, 1.825%, in each case over (A) the rate
which appears on page 3750 (or any successor page) of the Telerate Screen at or
about 11:00 a.m., London time, on the day such rate of interest is determined,
for deposits in Dollars with maturities of at least six days and not exceeding
six months, as the Agent may elect, as determined by the Agent upon consulting
the relevant page of the Telerate Screen, (B) if such rate is not available on
the relevant page of the Telerate Screen or if the Telerate Screen is
unavailable, the arithmetic mean (rounded upward, if necessary, to the nearest
1/16 of 1%) of the offered quotations in effect at or about 11:00 a.m., London
time, on the day such rate of interest is determined for deposits in Dollars
with maturities of at least six days and not exceeding six months, as the Agent
may elect, as displayed on the "LIBO" page (or any successor page as determined
by the Agent) of the Reuters Monitor Money Rates Service as determined by the
Agent upon consulting such "LIBO" page (or successor page) or (C) if the LIBO
page (or successor page) should be used pursuant to clause (B) but does not at
the time of determination display at least two offered quotations, the average
(rounded upward, if necessary, to the nearest 1/16 of 1%) of the respective
rates at which deposits in Dollars with maturities of at least six days and not
exceeding six months, as the Agent may elect, are offered to each of the
Reference Banks in the London interbank market as of approximately 11:00 a.m.,
London time, on the day such rate of interest is determined in an amount
approximately equal to the aggregate

                                                                              27




amount of such overdue payment due to the relevant Lenders.  If for any of the
reasons specified in clauses (i), (ii) or (iii) of Section 2.5 hereof an
alternative interest rate would be determined pursuant thereto, then such
alternative interest rate shall be determined and the Borrower shall pay to the
relevant Lenders interest on such overdue principal or other amounts at a rate
per annum that shall be (i) with respect to the period ending on the fourth
anniversary of the initial Borrowing Date hereunder, 2.10%, and (ii)
thereafter, 1.825%, in each case over such alternative interest rate without
the addition of the Applicable Margin.

                          (b)     To the extent permitted by applicable law,
without prejudice to the other rights of the Lenders under Sections 2.6(a) and
10.6(b) hereof, the Borrower shall indemnify, without duplication, each such
Lender against, hold each such Lender harmless from and promptly pay to the
Agent on behalf of each Lender all out-of- pocket costs, losses (excluding loss
of profit) or expenses which each such Lender may sustain or incur as a
consequence of (i) any portion of a Borrowing not being made, after notice
thereof has been given by the Borrower to the Agent (or a copy thereof has been
given by the Agent to the Finance Company), other than due to a breach by one
or more Lenders of its or their obligations hereunder, (ii) any prepayment of
any Advance (including any Deferred Portion thereof) or (iii) the failure by
the Borrower to pay when due the principal of or interest on any Note or any
other amount payable under this Agreement or the Letter Agreement, including
but not limited to breakage and other funding costs and any amounts payable by
such Lender in order to maintain its Advances, including any Deferred Portion
thereof, until the end of the relevant Interest Period in the event of
prepayment or until payment of all amounts then due by acceleration or
otherwise in the event of a failure to pay, but excluding any such costs,
losses or expenses resulting from prepayment on an Interest Payment Date of
amounts for which an Interest Period ends on such Interest Payment Date as
permitted in accordance with Section 3.7 hereof.  In each case involving a
prepayment (other than a prepayment under Section 3.7 hereof for which no
costs, losses or expenses are payable), each Lender shall act in good faith and
use reasonable efforts to minimize the costs, losses and expenses payable by
the Borrower hereunder.

                          (c)     A certificate of any Lender setting forth in
reasonable detail the basis for the determination of the amounts necessary to
indemnify such Lender pursuant to Section 2.6(b) shall be conclusive as to the
determination of such amounts in the absence of manifest error.

                 2.7      Fees.

                          (a)     The Borrower hereby agrees to pay a
non-refundable management fee and a non-refundable agency fee in the amount
specified in and otherwise in accordance with the management fee letter
agreement, of even date herewith, between the Borrower and the Lead Arranger
and the agency fee letter agreement, of
<PAGE>   33
                                                                              28




even date herewith, between the Borrower and the Agent and of even date
herewith (the management fee letter agreement and the agency fee letter
agreement are collectively referred to herein as the "Letter Agreement").

                          (b)     The Borrower agrees to pay to the Agent, for
the account of each Lender, a commitment fee at the rate of 0.175% per annum on
the daily undrawn amount of such Lender's Commitment during the period from and
including the Effective Date to and including the last day of the Availability
Period.  Such fee will be calculated on an estimated basis on the first day of
each Interest Period in accordance with the undrawn amount of such Lender's
Commitment on that day and amounts in respect thereof shall be accumulated for
payment and paid in accordance with Sections 3.2 and 3.3 of the Trust
Agreement, subject to adjustment when any Advance is made hereunder.  Such
commitment fee shall be calculated on the basis of the actual number of days
elapsed and a 360-day year and shall be paid in arrears, in accordance with
Section 3.2 hereof, initially on the first Interest Payment Date, thereafter on
each Interest Payment Date that occurs during the Availability Period and
finally on the Interest Payment Date on or immediately following the last day
of the Availability Period.

                 2.8      The Notes.  Each Lender's Advances shall be evidenced
by a single promissory note of the Borrower (each a "Note"), substantially in
the form of Exhibit C-1 hereto, each payable to the order of such Lender for
the account of its Lending Office in an amount equal to such Lender's
Commitment or, if less, the aggregate unpaid principal amount of such Lender's
Advances.  Each Note shall be dated the date of its delivery pursuant to
Section 5.1 hereof, shall have the blanks therein appropriately completed, and
shall bear interest as specified in Sections 2.3, 2.4, 2.5 and 2.6 hereof.
Each Lender shall, and is hereby irrevocably authorized by the Borrower to,
endorse on the schedule attached to its Note or on a continuation of such
schedule attached to and made a part of such Note an appropriate notation
evidencing the date and amount of each Advance made by such Lender and the date
and amount of each payment, prepayment or deferral of principal made by the
Borrower with respect thereto.  The failure so to record any such amount or any
error in so recording any such amount shall not, however, limit or otherwise
affect the obligations of the Borrower hereunder or under any of the Notes to
repay the principal amount of all Advances thereunder together with all
interest accruing thereon.

                 2.9      Repayment on Maturity Dates; Deferral.

                          (a)     Subject to Section 2.9(b) hereof, the
Borrower shall pay (i) on any Maturity Date (including any Special Maturity
Date), the Current Payment with respect to such Maturity Date, plus (ii) on any
Special Maturity Date, an amount of principal equal to the difference between
(x) the Current Amortized Amount and (y) the Prior Amortized Amount; provided
that on the Final Maturity Date the Borrower
<PAGE>   34
                                                                              29




shall repay in full the amount of the aggregate Advances then outstanding.  As
used herein, the following terms have the respective meanings assigned thereto
below:

                 "Applicable Amortization Percentage" means (i) with respect to
each of the 1st through 4th Maturity Dates, 1.5%, (ii) with respect to each of
the 5th through 12th Maturity Dates, 2.0%, (iii) with respect to each of the
13th through 24th Maturity Dates, 2.5% and (iv) with respect to each of the
25th to 40th Maturity Dates, 3.0%.

                 "Current Amortized Amount" means, with respect to any Special
Maturity Date, the sum of (i) the product of (x) the number of Maturity Dates
(if any) occurring prior to such Special Maturity Date with respect to which
1.5% is the Applicable Amortization Percentage, multiplied by (y) 1.5% of the
Funded Advances as of the Special Maturity Date, plus (ii) the product of (x)
the number of Maturity Dates (if any) occurring prior to such Special Maturity
Date with respect to which 2.0% is the Applicable Amortization Percentage,
multiplied by (y) 2.0% of the Funded Advances as of the Special Maturity Date.

                 "Current Payment" means, with respect to any Maturity Date, an
amount of principal equal to the Applicable Amortization Percentage with
respect to such Maturity Date of the Funded Advances as of such Maturity Date.

                 "Funded Advances" means, with respect to any Maturity Date
(including any Special Maturity Date), the aggregate principal amount of
Advances that have been made by the Lenders to the Borrower prior to such
Maturity Date, whether or not outstanding as of such Maturity Date.

                 "Prior Amortized Amount" means, with respect to any Special
Maturity Date, the sum of all amounts previously calculated to or repayable
pursuant to this Section 2.9(a) (whether or not actually repaid).

                 "Special Maturity Date" means each of the Maturity Dates
occurring on or prior to the end of the Availability Period and the Maturity
Date first occurring after the end of the Availability Period.

                          (b)     If after application of amounts to the
payment of interest and other amounts payable with respect to the Advances on
any Maturity Date other than the Final Maturity Date, the aggregate of the
amounts held in the Debt Service Account and the Reserve Account will be
insufficient on such Maturity Date to pay all or a portion of the principal
payable on such Maturity Date, then the Borrower may elect (by giving not later
than noon, New York time, on or prior to the eighth Business Day preceding such
Maturity Date an irrevocable Notice of Deferral to the Agent, which shall
promptly notify the Lenders thereof) to defer to the next succeeding Maturity
Date payment of the amount of principal for which such funds will be

                                                                              30




insufficient (pro rata for the account of each Lender to the unpaid principal
amount of the Notes) (such amount referred to as the "Deferred Portion"),
subject to the following being true on the Maturity Date on which such
insufficiency exists:

                                     (i)   The Borrower shall not have
         previously deferred payments of any principal in accordance with this
         Section 2.9(b) either (x) on the four consecutive Maturity Dates
         immediately preceding such Maturity Date or (y) on a total of 15
         previous Maturity Dates, whether or not consecutive;

                                     (ii)  Each LNG Sales Contract shall be in
         full force and effect;

                                    (iii)  No material breach or default under
         either LNG Sales Contract shall exist and no notice of incipient
         material breach or default shall have been given by any party thereto;

                                     (iv)  No authorization or approval
         required for the continued validity and enforceability of either LNG
         Sales Contract shall have been revoked or suspended; and

                                     (v)   No Event of Default shall have
         occurred and be continuing or would occur with the giving of notice or
         the lapse of time or both.

                 2.10     Notices.  The Agent shall promptly give the Borrower
and each of the Lenders (i) notice of each interest rate (or interest rates)
determined pursuant to Section 2.4, 2.5 or 2.6 hereof, the date of each of the
next Interest Payment Dates with respect to which the interest payable is then
calculable, the date of the next Maturity Date and the amount of principal or
interest, the amount of commitment fees estimated in accordance with Section
2.7(b) hereof to be paid to the Lenders on each of such dates and the amount of
the agency fee and the management fee provided for in the Letter Agreement,
(ii) as otherwise provided in this Agreement, notice of other relevant amounts
due and payable hereunder, (iii) upon the occurrence of the Effective Date,
notice to the effect that the Effective Date has occurred, and (iv) the notices
to the Borrower by the Agent that Section 3.2(b) of the Trust Agreement
requires this Agreement to provide for.  The Agent shall provide the foregoing
information to the Borrower at the time and in the manner specified in Section
3.2(b) of the Trust Agreement; provided that no failure or delay in the giving
of such notice shall discharge or excuse the Borrower from or permit the
Borrower to delay making any payment hereunder.

SECTION 3.       PAYMENTS

                 3.1      Allocation of Amounts; Substitute Payment.

                          (a)     Unless otherwise provided in this Agreement,
all payments by the Borrower to the Agent for the account of the Lenders or to
the Finance Company shall be allocated as provided for in Section 3.3 of the
Trust Agreement.  All payments by the Borrower of commitment fees shall be made
to the Agent for the account of the Lenders, pro rata to their respective
Commitments.  All payments referred to in this Section 3.1 which are received
by the Agent in the manner provided in Section 3.2 hereof shall be deemed to
have been made to the Lenders (other than the Finance Company), and the receipt
by the Agent of such payments shall discharge the Borrower from any further
liability to make such payments to the Lenders (other than the Finance
Company).

                          (b)     Notwithstanding anything to the contrary
contained in this Agreement or in any Note, but subject always to the
provisions of Section 9 hereof, if the Agent shall have notified the Borrower
that it shall have become unlawful or, in the opinion of the Agent,
impracticable for any payment payable to it to be made as aforesaid, the
Borrower shall pay to each Lender for its own account in such funds as are
required by Section 3.2 hereof or in such other manner as may be agreed between
the Borrower and the relevant Lender and to such account as may be specified by
the relevant Lender to the Borrower, the amount of the relevant Lender's
portion of the payment in question.  Each such Lender shall keep the Agent
fully informed as to all amounts received by it and as to all agreements made
between it and the Borrower as referred to above.

                 3.2      Funds of Payment.

                          (a)     Each payment made by the Borrower (other than
as provided in Section 3.2(b) hereof with respect to the Finance Company) under
this Agreement, the Notes or the Letter Agreement shall be made in Dollars and
in same day settlement funds by credit of Federal or other immediately
available funds satisfactory to the Agent (or such funds as may from time to
time be customary for the settlement in New York City of international banking
transactions in Dollars) not later than 11:00 a.m., New York time, on the
Business Day on which such payment is due by credit to the account of the Agent
(Account No. 323-5-09967) at The Chase Manhattan Bank, Administrative Agent,
Loan & Agency Services, 1 Chase Manhattan Plaza, 8th Floor, New York, New York
10081, U.S.A. or to such other account of the Agent as the Agent may at any
time or from time to time designate by written notice to the Borrower; provided
that, if and to the extent the Borrower shall have delivered a Notice of
Borrowing as provided herein that requests a Borrowing to pay for interest or
fees pursuant to Section 2.3, 2.6 or 2.7 hereof and if the Borrowing Date
applicable to
<PAGE>   37
                                                                              32




such Borrowing is also the date such payment is to be made to the Agent, then
such portion of such payment as shall be payable by the Borrower from the
proceeds of such Borrowing shall be made as soon as reasonably practical after
the Borrower receives the proceeds of such Borrowing, but in any case not later
than 1:00 p.m., New York time, on such Business Day.  The Agent will promptly
cause each such payment received by it to be distributed to each Lender (other
than the Finance Company) (in each case for the account of such Lender's
Lending Office) in like funds with respect to each payment received by such
Agent for the account of such Lenders or the holders of the Notes.

                          (b)     Each payment made by the Borrower with
respect to the Finance Company under this Agreement, the Note held by the
Finance Company or the Letter Agreement shall be made in Dollars and in same
day settlement funds by credit of Federal or other immediately available funds
satisfactory to the Finance Company (or such funds as may from time to time be
customary for the settlement in New York City of international banking
transactions in Dollars) not later than 10:00 a.m., Tokyo time, on the Business
Day on which such payment is due.  To effectuate the foregoing sentence and to
ensure that the Finance Company and the other Lenders receive such payments on
the same calendar date in their respective time zones, the Borrower shall
issue, not later than one Business Day prior to the Business Day on which any
such payment is due, an irrevocable payment order in favor of the Finance
Company for value on the Business Day on which such payment is due in the full
amount of such payment, such irrevocable payment order to be addressed to the
Finance Company's bank in Tokyo, Japan (Account No. 02USD07189980-01) at The
Long-Term Credit Bank of Japan, Limited, Tokyo Headquarters, 1-8, Uchisaiwaicho
2-chome, Chiyoda-ku, Tokyo 100 Japan, or to such other bank or account of the
Finance Company in Tokyo, Japan as the Finance Company may at any time or from
time to time designate by written notice to the Borrower.  The receipt by the
Finance Company of such payment in accordance with such irrevocable payment
order shall fully discharge the Borrower's obligations with respect to the
amount paid.  If and to the extent the Borrower shall have delivered a Notice
of Borrowing as provided herein that requests a Borrowing to pay for interest
or fees pursuant to Section 2.3, 2.6 or 2.7 hereof, and if the Borrowing Date
applicable to such Borrowing is also the date such payment is to be made to the
Finance Company, then the payment order referred to in the second preceding
sentence shall expressly provide that payment pursuant thereto shall be subject
to the receipt by the Borrower by 1:00 p.m., New York City time, on the
relevant Borrowing Date of immediately available funds in the amount requested
in such Notice of Borrowing.

                          (c)     Whenever any payment hereunder or under any
Note falls due on a day which is not a Business Day, the due date for such
payment shall be advanced to the next succeeding Business Day, unless the next
succeeding Business
<PAGE>   38
                                                                              33




Day falls in another calendar month, in which case such payment shall be the
immediately preceding Business Day.

                 3.3      Set-Off, Counterclaim and Taxes.  The Borrower will
(i) pay all amounts of principal of and interest on the Notes and all other
amounts payable under this Agreement, the Notes and the Letter Agreement
("Payments") without set-off or counterclaim, and, to the extent permitted by
law, free and clear of, and without deduction or withholding for or on account
of, any Taxes, and (ii) pay to, indemnify for and hold each of the Lenders
harmless from and against any Taxes which are stamp or like taxes imposed
directly or indirectly with respect to the preparation, execution, delivery,
registration, filing or recording of this Agreement, the Notes, the Producers
Agreement, the Trust Agreement, the Letter Agreement or any document connected
herewith or therewith and any Taxes which are imposed directly or indirectly on
any Lender or the Agent, with respect to this Agreement, the Notes, the
Producers Agreement, the Trust Agreement, the Letter Agreement, any document
connected herewith or therewith or the transactions contemplated by any of the
foregoing documents or any Payments.  Notwithstanding the foregoing, the
provisions of the first sentence of this Section 3.3 shall not require the
Borrower to indemnify for any Excluded Taxes.  If any Taxes (other than
Excluded Taxes) are required by law to be deducted or withheld from any
Payment, the Borrower will increase the amount of such Payment to the Agent,
the Finance Company or the Lenders through the Agent, as the case may be, to
the extent necessary in order that the net amount received by the Agent, the
Finance Company or the Lenders through the Agent, as the case may be, after
deduction of all Taxes required to be deducted or withheld with respect to such
Payment as so increased and any other Taxes payable by the Lenders with respect
to the amount of such increase, will equal the full amount of the Payment due
and payable to the relevant Lender or Lenders.  The Borrower will furnish to
each Lender, in such number of copies as such Lender shall request, certified
copies of tax receipts or other appropriate evidence of payment, satisfactory
to such Lender, evidencing the payment of all Taxes levied or imposed upon any
Payment within 45 days after the date any such payment is due pursuant to
applicable law.  If any Taxes (other than Excluded Taxes) are imposed on or
with respect to any Payment or are required to be paid by the Agent or any
Lender on or with respect to any Payment or in connection with this Agreement
or the Notes, the Borrower will pay or otherwise indemnify and hold the Agent
and each Lender harmless from any such Taxes or will reimburse to the Agent and
each Lender on demand, subject to the provisions of Section 3.10 hereof, such
amounts as may be necessary in order that the net amount received by the Agent
and each Lender pursuant to such indemnity or reimbursement, after deduction of
all Taxes required to be deducted, withheld or otherwise paid by the Agent and
the Lenders with respect to such amount, shall equal the amount of such Taxes
so imposed or otherwise subject to indemnity and reimbursement.
<PAGE>   39
                                                                              34




                 If a Lender shall receive a refund of any Taxes paid by the
Borrower pursuant to this Section 3.3 by reason of the fact that such Taxes
were not correctly or legally asserted, the Lender shall within 45 days after
receipt of such refund pay to the Borrower the amount of such refund, as
determined solely by the Lender; provided, however, that in no event shall the
amount paid by the Lender to the Borrower pursuant to this sentence exceed the
amount of Taxes originally paid by the Borrower; and provided, further, that no
Lender shall have any obligation under this Agreement to claim or otherwise
seek to obtain any such refund.

                 3.4      Change of Law; Certain Mandatory and Voluntary
Prepayments; Additional Amounts.

                          (a)     Notwithstanding any other provision in this
Agreement to the contrary, if any change in any applicable law, rule or
regulation or in the interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by any Lender (or its Lending Office) with any new
request, interpretation or directive of any relevant central bank or other
governmental authority, shall make it unlawful for any Lender (or its Lending
Office) to (i) maintain its Commitment, then such Commitment of such Lender
shall thereupon terminate, or (ii) maintain or fund its Advances, then such
Commitment of such Lender shall thereupon terminate, and the principal amount
of such Lender's Note then outstanding shall be repaid, together with interest
accrued thereon and any other amounts payable to such Lender under this
Agreement, such Lender's Note or the Letter Agreement, commencing immediately
as an accelerated mandatory prepayment in accordance with Sections 3.2 and 3.3
of the Trust Agreement; provided, however, that all such amounts shall be paid
on or prior to the Final Maturity Date.  Upon the occurrence of any such change
or request making it unlawful for a Lender to maintain its Commitment as
aforesaid, such Lender shall promptly forward to the Agent in writing, and the
Agent shall promptly forward to the Borrower, evidence certified by such Lender
as to such change or request.

                          (b)     If any change in any applicable law, rule or
regulation or in the interpretation or administration thereof, or compliance by
any Lender with any request (whether or not having the force of law) of any
relevant central bank or other governmental authority, shall change the basis
of taxation of payments to any such Lender (or its Lending Office) of the
principal of or interest on any of the Notes or any other amounts payable under
this Agreement or the Letter Agreement (except for Excluded Taxes) or shall
impose, modify or deem applicable any similar requirement not in effect on the
date of this Agreement in respect of Reserves against assets of, deposits with
or for the account of, or credit extended by, or the Commitment of, any such
Lender (or its Lending Office) (except for Reserves in effect on the date of
this Agreement), or shall impose on any such Lender (or its Lending Office) or
the London interbank market any other condition not in effect on the date of
this Agreement

                                                                              35




directly affecting this Agreement, any of the Notes, the Letter Agreement or
the Advances and the result of any of the foregoing is to increase the cost to
any Lender of maintaining its Commitment or making or maintaining its Advances,
or to reduce the amount of any such payments received or receivable by any such
Lender (or its Lending Office) hereunder, by an amount deemed by such Lender to
be material, then the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender for such additional cost or
reduction.  Such additional amount or amounts shall be paid on the Interest
Payment Date for the Interest Period to which such costs relate.  Each Lender
agrees that it will promptly notify the Borrower of any event which will
entitle such Lender to an additional amount pursuant to this Section 3.4(b).  A
certificate of such Lender setting forth the basis in reasonable detail for the
determination of such additional amount necessary to compensate such Lender as
aforesaid shall be conclusive as to the determination of such amount in the
absence of manifest error.  After the receipt of any notice from any Lender
indicating that such Lender is entitled to an additional amount pursuant to
this Section 3.4(b), the Borrower may elect to prepay the relevant Note or
Notes of such Lender without premium or penalty (except as provided in Section
2.6(b) hereof) in accordance with the provisions of Section 3.6 hereof;
provided that any such prepayment may be made only if the amounts set forth in
the certificate described in the preceding sentence are paid by the Borrower
prior to or simultaneously with such prepayment.

                          (c)     Each Lender (other than the Finance Company)
agrees that, upon the occurrence of any event giving rise to the operation of
Section 3.4(a) or (b) hereof with respect to such Lender, it will, if requested
by the Borrower, and in consultation with the Agent, use its best efforts to
designate another Lending Office for its Commitment or its Advances and/or for
a period of thirty calendar days after the date of such request use reasonable
efforts to transfer its Commitment and Advances to another Person in accordance
with the procedures set forth in Section 10.4, in either case with the object
of avoiding the consequence of the event giving rise to the operation of
Section 3.4(a) or (b) hereof; provided that in either case such designation or
transfer can be made on such terms that such Lender and its Lending Office
suffer no economic, legal or regulatory disadvantage.  Nothing in this Section
3.4(c) shall affect or postpone any of the obligations of the Borrower or the
rights of the Lenders provided in Section 3.4(a) or (b) hereof.

                 3.5      Prepayments in Connection with Completion of Train H;
Debt Coverage Reserve Mandatory Prepayments.

                          (a)     Any amounts borrowed hereunder and not used
as provided in Section 2.2(a) hereof in connection with the completion of Train
H or otherwise used as provided in Section 2.2(b) hereof, shall be repaid to
the Lenders, or applied on the Lenders' behalf, on the Interest Payment Date
ending the Quarterly
<PAGE>   41
                                                                              36




Period then in effect in accordance with the provisions of Section
3.7(c)(ii)(1) of the Trust Agreement.

                          (b)     If during any Quarterly Period the Borrower
shall have paid into the Debt Coverage Reserve Account any Source of Debt
Service pursuant to Section 3.2 of the Trust Agreement or any other amount
pursuant to Sections 3.3(a)(vii) and 3.3(b)(vi) of the Trust Agreement (as
provided in Section 9.3 hereof), then on the Maturity Date occurring at the end
of such Quarterly Period the Borrower shall apply the Source of Debt Service so
accumulated in the Debt Coverage Reserve Account to prepay the Notes on a pro
rata basis (based on outstanding principal amount), with such prepayment to be
applied to the installments of principal due thereunder in the inverse order of
maturity; provided that for purposes of further calculations of the Debt
Coverage Ratio any such prepayment shall be deemed to have been applied to such
installments of principal pro rata so that the Final Maturity Date is not
thereby changed.

                 3.6      Notice of Certain Voluntary Prepayments.  Whenever
the Borrower has elected to prepay any relevant Note or Notes or any Deferred
Portion thereof pursuant to Section 2.5 or 3.4(b) hereof, the Borrower shall
give the Agent notice (and shall give a copy to the Finance Company on which
the Finance Company may rely as if addressed to it as a Lender hereunder) of
such prepayment not later than noon, New York City time, on or prior to the
eighth Business Day preceding the date of such prepayment, and on the date
specified in such notice (which shall be a Business Day and a single date) the
principal then outstanding of the affected Note or Notes shall be repaid in
full, together with interest accrued thereon, and, to the extent then
ascertainable, any other amount payable under this Agreement to the Lender or
Lenders holding such Note or Notes.  Any notice of prepayment under this
Section 3.6 shall be irrevocable.  Without limiting the right of the Borrower
to prepay the Notes in the manner provided in Section 2.5 or 3.4(b) and upon
the prior notice as provided above in this Section 3.6, the Borrower shall use
its best efforts (without incurring any liability additional to that provided
for in Section 9.5 hereof) to provide the Agent with as much prior written
notice (with a copy to the Finance Company on which the Finance Company may
rely as if addressed to it as a Lender hereunder) of its intention to prepay
any of the Notes pursuant to Section 2.5 or 3.4(b) as is reasonably possible in
the circumstances.

                 3.7      Other Voluntary Prepayments.  The Borrower may, upon
irrevocable prior notice to the Agent (with a copy to the Finance Company on
which the Finance Company may rely as if addressed to it as a Lender hereunder)
given not later than noon, New York City time, on or prior to the eighth
Business Day preceding the date of such prepayment, prepay the Notes in whole
or in part on a pro rata basis (based on outstanding principal amount) on any
Interest Payment Date for the Notes being prepaid, and, if in part, in an
amount which is equal to $1,000,000.00 or an

integral multiple of $1,000,000.00.  Each partial prepayment of any Notes made
pursuant to this Section 3.7 shall be applied to the installments of principal
due thereunder in the inverse order of maturity.  Except as provided in Section
2.6(b) hereof, such prepayments shall be without premium or penalty; provided
that the right to prepay without premium or penalty shall not apply to any
amounts declared forthwith due and payable in accordance with Section 7 hereof.
All prepayments permitted pursuant to this Section 3.7 shall be made together
with payment of accrued interest on the principal amount prepaid, and, to the
extent then ascertainable, any other amount payable under this Agreement, the
Notes or the Letter Agreement.  Without limiting the right of the Borrower to
prepay the Notes in the manner and upon the prior notice as provided above in
this Section 3.7, the Borrower shall use its best efforts (without incurring
any liability additional to that provided for in Section 9.5 hereof) to provide
the Agent (and shall provide a copy to the Finance Company on which the Finance
Company may rely as if addressed to it as a Lender hereunder) with 30 days'
prior written notice of its intention to prepay all or any portion of the Notes
pursuant to this Section 3.7.

                 3.8      Cancellation of Commitments.  The Borrower may
without premium or penalty (i) upon not less than 30 days' irrevocable prior
notice to the Agent (with a copy to the Finance Company on which the Finance
Company may rely as if addressed to it as a Lender hereunder), cancel the
Commitments of the Lenders in whole or in part, and if in part in an aggregate
amount of $1,000,000.00 or an integral multiple of $1,000,000.00, all such
cancellations to be on a pro rata basis as among the Lenders based on their
respective Commitments, or (ii) upon irrevocable notice given simultaneously
with or as part of the notice given pursuant to Section 3.6 hereof to any
Lender whose Note is prepaid in accordance with the provisions of Section 3.6
hereof, cancel the Commitment of such Lender.

                 3.9      No Reborrowing.  The Commitments are not revolving in
nature, and no amount repaid or prepaid under this Agreement may be reborrowed
hereunder.

                 3.10     Payments to be Made at End of Interest Period.
Except for amounts owing pursuant to Sections 3.4(a), 7 and 10.6 hereof which
become payable as provided in such Sections, and notwithstanding any provision
of any Section other than Sections 3.4(a), 7 and 10.6 hereof to the contrary,
in view of the nature of the Borrower and the nature of the Source of Debt
Service from which payments hereunder will be made, all amounts becoming
payable hereunder, which would otherwise be due on a date which does not fall
on an Interest Payment Date instead shall be due on the Interest Payment Date
next to occur thereafter and prior to which the Borrower is notified that such
amount is payable, subject in each such case to the relevant provisions of
Sections 3.2 and 3.3 of the Trust Agreement; provided, however, that all
amounts due and payable under this Agreement, the Letter Agreement and the
Notes shall be paid on or prior to the Final Maturity Date.

provided under this Section 6.1 to be distributed to each Lender.

                 6.2      Negative Pledge.  The Borrower will not create, incur
or suffer to exist any Encumbrance on the Source of Debt Service received or
receivable by it prior to its deposit in the Bontang VI Payment Account, or any
Encumbrance on any Borrowed Amounts, in each case resulting from any act or any
failure to perform any obligation of the Borrower under this Agreement or of
the Bontang VI Trustee under the Trust Agreement or any duty as Bontang VI
Trustee, except any Encumbrance, if any, (i) arising pursuant to the Trust
Agreement or in favor of the holders of Indebtedness permitted in accordance
with Section 6.4 hereof or (ii) arising pursuant to statute or otherwise by
operation of law, and not pursuant to any agreement, which is discharged in the
ordinary course of business and which is not enforced by attachment or levy.

                 6.3      No Consent to Changes.  The Borrower will not (i)
terminate or revoke the Trust Agreement, or (ii) amend, modify, revise,
supplement or waive any of the provisions of (a) Article 1, 4 or 10 or Section
2.1, 2.2, 2.4, 3.1, 3.2, 3.3, 3.4 (other than Section 3.4(e)), 3.5, 3.7 or 3.9,
or the third sentence of Section 8.2 of the Trust Agreement, in each case other
than to permit the Borrower to enter into Subordinated Indebtedness or Pari
Passu Swap Indebtedness, or (b) any other provision of the Trust Agreement if
any such amendment, modification, revision, supplement or waiver would or would
be likely to have an adverse effect on the trust created under such Trust
Agreement, or the rights of the Lenders under or the ability of the Borrower to
perform its obligations under this Agreement, the Notes or the Letter
Agreement.  Any consent of the Majority Lenders necessary to permit any action
otherwise prohibited by this Section 6.3 shall not be unreasonably withheld.

copies of any agreement or document evidencing any revocation, amendment,
modification or revision of the Trust Agreement or any provision thereof not
requiring the consent of the Majority Lenders under this Section 6.3.

Indebtedness (a) that shall be payable out of amounts of the Source of Debt
Service only after (x) the Trustee shall have accumulated amounts in the Debt
Service Account and the Reserve Account during each Interest Period required to
be accumulated therein pursuant to Sections 7 and 9 hereof and (y) any amounts
required to be deposited in the Debt Coverage Reserve Account and paid to the
Lenders therefrom under Section 9 hereof have been so deposited and paid, (b)
the terms and conditions of which have been approved as to form and substance
by the Majority Lenders, such approval not to be unreasonably
<PAGE>   55
                                                                              50




withheld, and (c) the proceeds of which shall be applied solely in connection
with the Bontang Plant (the Indebtedness referred to in this clause (ii),
"Subordinated Indebtedness") and (iii) with respect to Source of Debt Service
only, obligations (other than Subordinated Indebtedness) in respect of interest
rate swap arrangements of the Borrower entered into solely for the purpose of
exchanging floating interest rate obligations with respect to the aggregate
Commitments or the Advances outstanding under this Agreement for fixed interest
rate obligations, if such Indebtedness is pari passu in right of payment and
does not benefit from any Encumbrance other than equally and ratably with, or
subordinate to, the Indebtedness owed to the Lenders under this Agreement, the
Notes and the Letter Agreement and if the terms and conditions of such
arrangements are approved as to form and substance by the Majority Lenders
("Pari Passu Swap Indebtedness"), such approval not to be unreasonably
withheld; provided that the withholding of any consent by the Majority Lenders
under either Section 6.4(ii) or Section 6.4(iii) shall be deemed reasonable if
the Borrower and the Majority Lenders are unable to agree with respect to (x)
amendments to this Agreement, including without limitation amendments to the
definition of "Debt Coverage Ratio," with respect to such Subordinated
Indebtedness or Pari Passu Swap Indebtedness, as the case may be, (y)
amendments to the Trust Agreement relating to such Subordinated Indebtedness or
Pari Passu Swap Indebtedness, as the case may be, or (z) such other changes to
the terms and conditions, including the Events of Default, of the Trust
Agreement, the Producers Agreement and this Agreement as the Majority Lenders
shall request in connection with such Subordinated Indebtedness or Pari Passu
Swap Indebtedness, as the case may be.  The Borrower shall not create, assume
or become liable for, directly or indirectly, any Indebtedness charging or to
be paid out of any Borrowed Amounts, except for Indebtedness for which such
Borrowed Amounts were borrowed.

                 6.5      Notice of Outstanding Amounts and Repayment Schedule.
Promptly after (i) the beginning of the Amortization Period, (ii) each
Borrowing Date occurring thereafter prior to the end of the Availability Period
and (iii) the end of the Availability Period, the Agent shall deliver to the
Borrower a notice setting forth the outstanding amounts of principal and
interest as of the most recent Borrowing Date and a repayment schedule.  In
each case, the Borrower shall either promptly confirm that it agrees with such
amounts and such schedule by signing and returning to the Agent a copy of such
notice or promptly deliver to the Agent a notice indicating that it does not
agree and specifying the reasons therefor.  The delivery or lack of delivery of
any such notice to the Borrower shall in no way affect any of the obligations
of the Borrower pursuant to this Agreement other than those set forth in this
Section 6.5.

                 6.6      Selection of Qualified Bank.

                          (a)     If at any time the assumptions necessary for
calculating the Debt Coverage Ratio are, pursuant to the definition of Debt
Coverage Ratio, to be
<PAGE>   56
                                                                              51




specified by a Qualified Bank, either (i) the Borrower shall select, no later
than 15 Business Days after the request for negotiations referred to in the
relevant definition, one of the banks listed on Schedule 4 hereto (as such
Schedule 4 may be amended by the Borrower and the Agent from time to time),
other than any such bank with respect to which the Agent has, within 10
Business Days after the request for negotiations in question, given written
notice of its reasonable objection or (ii) (x) if the Borrower shall not have
selected a bank as provided in the foregoing clause (i), (y) if at any time all
of the banks on Schedule 4 have been so objected to in one or more such notices
or (z) if such Qualified Bank shall not have specified such assumptions, as the
case may be, within 10 Business Days after being selected, the Agent shall
select the Qualified Bank with the consent of the Borrower, such consent not to
be unreasonably withheld; provided, however, that for purposes of the
foregoing, a failure to respond to a request for such consent within three
Business Days shall be deemed to be the granting of such consent.  A Qualified
Bank so selected is referred to herein as a "Selected Qualified Bank."  The
Selected Qualified Bank shall render a written report addressed to the
Borrower, the Producers and the Agent setting forth its determination and
containing a statement to the effect that it is qualified and able to make a
fair, informed and impartial decision concerning the matters submitted to it
for its decision.  On or prior to the first day of the Amortization Period, the
fees and charges of Selected Qualified Banks may be paid by the Borrower out of
Borrowings drawn down for such purpose (and, if so borrowed, shall be paid out
of such Borrowings), and following the first day of the Amortization Period,
such fees and expenses may be paid as contemplated by Section 3.3(b)(iv) of the

                                                                              52




                          (a)     (i) failure to make any payment of the
principal of any of the Notes within two days following, or interest on any of
the Notes within three days following, the date when due and payable in
accordance with the terms hereof and thereof (provided that for the purposes of
this clause (i) a deferral of payment of an amount of principal pursuant to
Section 2.9(b) hereof shall not be deemed to be a failure to make such
payment), or (ii) failure to pay any other amounts payable under this
Agreement, any of the Notes or the Letter Agreement within seven days following
the date when due in accordance with the terms of this Agreement, including
Section 3.10 hereof; or

                          (b)     any representation or warranty made or deemed
made by or on behalf of the Borrower in Section 4 or Section 5.2 of this
Agreement or in any certificate delivered to the Agent or the Lenders pursuant
hereto shall prove to have been incorrect or misleading in any material respect
as of the date when made; or

                          (c)     failure by the Borrower to perform or observe
any term, covenant or agreement contained in Section 6.2, 6.3 or 6.4 hereof; or

                          (d)     failure by the Borrower to perform its
obligations under Section 6.1(d) hereof for seven days after written notice of
such failure shall have been given to the Borrower by the Agent at the request
of any Lender; or

                          (e)     any failure by the Borrower to perform or
observe any term, covenant or agreement contained in this Agreement (other than
those referred to in clauses (a), (b), (c), (d) or (f) of this Section 7), or
any failure by the Borrower or any Producer to perform or observe any term,
covenant or agreement contained in the Trust Agreement, for 30 days after
written notice of such failure shall have been given to the Borrower by the
Agent at the request of any Lender; or

                          (f)     a Default as defined in the Producers
Agreement;

then the Agent shall, upon the written request of the Majority Lenders, by
notice of default given to the Borrower, (i) declare the Commitment of each
Lender to be forthwith terminated and/or (ii) declare all the Notes outstanding
hereunder to be forthwith due and payable, whereupon the then outstanding
principal amount of such Notes, together with accrued interest thereon and any
and all other amounts due under this Agreement and the Letter Agreement, shall
forthwith become due and payable without diligence, presentment, demand,
protest, notice of dishonor, or other notice of any kind, all of which are
hereby expressly waived by the Borrower.

                 Should the principal amount of the Notes be declared or become
due and payable in the foregoing manner, the entire amount of the Source of
Debt Service received by the Borrower thereafter shall to the extent provided
by the Trust
<PAGE>   58
                                                                              53




Agreement, as and when received by the Borrower, be accumulated and paid to the
Agent, for application to the amounts owing by the Borrower under this
Agreement, the Notes which were declared to be or which became due and payable
and the Letter Agreement until all principal of and interest on such Notes and
all other amounts then due and payable under this Agreement, the relevant Notes
and the Letter Agreement shall have been paid in full.


SECTION 8.  AGENT, ETC.

                 The Lenders, the Agent and the Arrangers agree among
themselves and, where the context of Section 8.9 or 8.10 so requires, with the
Borrower:

                 8.1      Appointment and Authority.

                          (a)     Each Lender (other than the Finance Company),
and each subsequent holder of any Note by its acceptance thereof, irrevocably
authorizes the Agent to receive all payments of principal, interest and other
amounts due to such Lender or such holder under this Agreement and the Notes.
Each Lender (including the Finance Company), and each subsequent holder of any
Note by its acceptance thereof, irrevocably authorizes the Agent to take all
other actions on behalf of such Lender or such holder and to exercise the
powers hereunder as are specifically delegated to the Agent by the terms
hereof, together with all other such powers as shall be reasonably incidental
thereto.

                          (b)     The relationship between each of the Lenders
and the Agent is and shall be that of agent and principal only, and nothing
herein shall be construed to constitute the Agent a trustee for any holder of a
Note or of a participation therein nor to impose on the Agent duties and
obligations other than those expressly provided for herein nor to confer upon
the Agent any fiduciary relationship or other relationship of agency or trust
with the Borrower.  Neither the Agent, nor any of its directors, officers,
employees or agents shall be liable to any of the Lenders for any action taken
or omitted to be taken by it or them hereunder or in connection herewith,
whether as a result of any conflicts affecting or involving the Agent resulting
from its responsibilities relating to this Agreement, the Commitments, the
Advances or otherwise, except for its own gross negligence or willful
misconduct.  Each of the Lenders, and each subsequent holder of any Note by its
acceptance thereof, agrees (which agreement shall survive payment of the Notes)
to indemnify the Agent (to the extent not reimbursed by the Borrower) in
amounts which are pro rata to the respective Commitments of such Lenders and,
in the case of a subsequent holder of any Notes, of the Lender from whom such
holder acquired (directly or indirectly) such Notes, from and against any and
all losses, claims, damages, liabilities and expenses of any kind (including
failure to receive any payment specified in the Letter Agreement) which may
<PAGE>   59
                                                                              54




be imposed on, incurred by or asserted against the Agent (in its capacity as
such) in any way related to or arising out of this Agreement or any Advances or
any action taken or omitted by such Agent under this Agreement whether as a
result of any conflicts affecting or involving the Agent resulting from its
responsibilities relating to this Agreement, the Commitments, the Advances or
otherwise, except (i) normal administrative expenses incidental to the
performance of duties as such Agent hereunder and (ii) any losses, claims,
damages, liabilities or expenses resulting from its or their gross negligence
or willful misconduct.

                 8.2      Agent May Rely on Documents.  The Agent shall be
entitled to rely on any communication, instrument or document reasonably
believed by it to be genuine and correct and to have been signed or sent by the
proper Person or Persons, and with respect to all legal matters shall be
entitled to rely on the advice of legal and other professional advisors
selected by it from time to time concerning all matters relating to this
Agreement, the Notes and its duties hereunder and thereunder, and shall not be
liable to any of the Lenders for the consequences of such reliance.

                 8.3      No Amendment to Duties of Agent Without Consent.  The
Agent shall not be bound by any waiver, amendment, supplement or modification
of this Agreement which affects its duties under this Agreement unless it shall
have given its prior written consent, as Agent, thereto.

                 8.4      Responsibilities of Agent.  The Agent may treat the
payee of any Note as the holder thereof until written notice of the transfer
thereof shall have been received by it pursuant to Section 10.4 hereof.  The
Agent does not make any warranty or representation to any Lender, and shall not
be responsible for any recitals, statements, representations or warranties
herein or in any document prepared by or given by the Borrower or any other
Person to the Lenders in connection herewith (or for the accuracy or
completeness of any such document) or for the execution, effectiveness,
genuineness, validity or enforceability of this Agreement or the Notes or any
other document, agreement or instrument delivered in connection herewith or
related hereto, or be liable for failing to make any inquiry concerning the
performance or observance of any of the terms, provisions or conditions of this
Agreement or any Note or any other document, agreement or instrument delivered
in connection herewith or related hereto.  The Agent shall be entitled to
retain for its own use any amounts paid to it in its capacity as such.  The
Agent shall not be deemed to have known of the occurrence of an Event of
Default or other event the occurrence or non-occurrence of which with the
giving of notice or lapse of time or both would become an Event of Default or
comparable event under any other agreement unless the Agent has received
written notice from a Lender or the Borrower specifying such Event of Default
or other event and stating that such notice is a "Notice of Default" or from
any other relevant Person so specifying.  If (i) the Agent receives a
notification pursuant to the preceding sentence, or (ii) the Borrower fails to
pay in accordance with the terms hereof to the
<PAGE>   60
                                                                              55




Agent when due the principal of or interest on any Note or any commitment fee
payable to any Lender hereunder, the Agent shall promptly give written notice
thereof to the Lenders.  The Agent may decline to take any action except upon
the written direction of the Majority Lenders in accordance with the voting
procedures agreement entered into by the Lenders and the Agent on the date
hereof and the Agent may obtain a ratification by such Majority Lenders of any
action taken by it under this Agreement or any other document, agreement or
instrument delivered in connection herewith or related hereto as provided in
such voting procedures agreement.  The Agent shall have no liability to the
Lenders for any action taken by it upon the direction of the Majority Lenders
or if ratified by the Majority Lenders, nor shall the Agent have any such
liability for any failure to act unless the Agent has been instructed to act by
the Majority Lenders.  The action of the Majority Lenders shall in each case
bind all of the Lenders hereunder.  The Agent shall not be required to take any
action which exposes the Agent to personal liability (unless indemnified to its
satisfaction for any and all consequences of such action) or which is contrary
to this Agreement or any Legal Requirement.

                 8.5      Funding Costs of Agent.  If at any time the Agent
makes available to a Lender amounts due from the Borrower hereunder which the
Borrower has failed to make available to the Agent, then the Lender shall on
first demand forthwith refund such amounts to the Agent together with interest
thereon at the rate offered by the Agent for overnight Dollar deposits in the
New York Federal Funds market.

                 8.6      Agent in Individual Capacity.  The Agent and its
affiliates in their capacities as Lenders shall have the same rights and powers
hereunder as any Lender and may exercise such rights and powers as though the
Agent were not the Agent.  The Agent and its affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to and
generally engage in any kind of banking, trust or other business with the
Borrower, any of the Borrower's affiliates, the Producers and any of the
Producers' affiliates, as if such Agent were not acting in such capacity
hereunder.

                 8.7      Credit Decision.  Each Lender represents, warrants
and acknowledges that it has, independently and without reliance upon the
Agent, the Arrangers or any other Lender, and based on such 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 Agent, the Arrangers or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.
<PAGE>   61
                                                                              56




                 8.8      Arrangers and Co-Agents.  Nothing in this Agreement
shall impose on the Arrangers or the Co- Agents, in their capacity as such, any
duties or obligations whatsoever among themselves or in favor of the Lenders or
any of them.

                 8.9      Change of Administrative Office of Agent.  The Agent
may at any time or from time to time by written notice to the Borrower and to
each Lender designate a different office from which its duties as Agent will
thereafter be performed; provided that no such change to a location outside of
the City of New York shall be made without the Borrower's consent, which
consent shall not be unreasonably withheld.

                 8.10     Successor Agent.  Subject to the appointment and
acceptance of a successor Agent as provided below, the Agent may resign at any
time by giving written notice thereof to the Lenders and to the Borrower.  The
Agent may be removed at any time with or without cause by the Majority Lenders.
Upon any such resignation or removal, such Majority Lenders shall have the
right to appoint such successor Agent.  If no successor Agent shall have been
so appointed by such Majority Lenders and shall have accepted such appointment
within 30 days after any such retiring Agent's giving of notice of resignation,
then such retiring Agent may appoint such successor Agent.  No successor Agent
shall be appointed without the consent of the Borrower, which consent shall not
be unreasonably withheld or delayed.  Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of such retiring Agent, and such retiring Agent shall be discharged from its
duties and obligations hereunder; provided, however, that the retiring Agent
shall not be discharged of any liability for any breach of its duties and
obligations hereunder prior to such acceptance.  After any such retiring
Agent's resignation hereunder as Agent, the provisions of this Section 8 shall
continue in effect for its benefit in respect of any actions taken or omitted
to be taken by it while it was acting as any such Agent hereunder.


SECTION 9.  SOURCE OF DEBT SERVICE; NO RECOURSE

                 9.1      Accumulation for Debt Service.  Pursuant to Sections
3.2 and 3.3 of the Trust Agreement and except as therein stated, the Borrower
shall pay (i) into the Debt Service Account the entire amount of all Borrowed
Amounts (other than the Reserve Account Borrowed Amount, if any) immediately
upon receipt thereof, (ii) into the Reserve Account the entire amount of the
Reserve Account Borrowed Amount, if any, immediately upon receipt thereof and
(iii) subject to Section 9.2(b), into the Debt Service Account the entire
amount of each payment of the Source of Debt Service, as and when actually
received by the Borrower, until the aggregate amount accumulated in the Debt
Service Account shall be sufficient to pay the principal of and interest due on
<PAGE>   62
                                                                              57




all of the Notes, as well as all other amounts due and payable under this
Agreement, the Notes and the Letter Agreement, in each case during such
Quarterly Period.  All such principal, interest and other amounts due during
any Interest Period are referred to herein as the "Quarterly Debt Service" for
such Interest Period.

                 9.2      Accumulation in Regular Reserve Account.

                          (a)     Pursuant to Sections 3.2 and 3.3 of the Trust
Agreement, during each Quarterly Period that ends on a Maturity Date, after all
amounts of Source of Debt Service required to be paid into the Debt Service
Account pursuant to Section 9.1 hereof with respect to such Quarterly Period
have been so paid, the Borrower shall pay into the Regular Reserve Account the
entire remaining amount of each payment of the Source of Debt Service, as and
when actually received by the Borrower, until the aggregate amount accumulated
in such Regular Reserve Account shall equal 100% of the amount of Quarterly
Debt Service reasonably anticipated to be due during the two Quarterly Periods
next succeeding such Quarterly Period.  For purposes of determining such
amounts of Quarterly Debt Service, the interest rate applicable to the Advances
(including any Deferred Portion thereof) scheduled to be outstanding during
each of such two succeeding Quarterly Periods shall be or be deemed to be the
interest rate, if any, then in effect in respect of principal to be outstanding
during the next succeeding Interest Period and, if no such rate shall then be
in effect, shall be deemed to be the interest rate in effect for the then
current Interest Period.

                          (b)     Notwithstanding Sections 9.1 and 9.2(a)
hereof, if there is any Source of Debt Service during the period from and
including January 1, 2000 to and including the first day of the Amortization
Period, the Borrower shall pay the full amount thereof into the Regular Reserve
Account pursuant to Section 3.2 of the Trust Agreement, as and when actually
received by the Borrower, until the aggregate amount accumulated in the Regular
Reserve Account shall equal 100% of the amount of Quarterly Debt Service
reasonably anticipated (in the manner prescribed in Section 9.2(a) hereof) to
be due on the first two Maturity Dates.

                 9.3      Deposit in Debt Coverage Reserve Account.  Pursuant
to Section 3.2 of the Trust Agreement, if at any time at or after the beginning
of the Amortization Period the Certificate delivered to the Agent pursuant to
6.1(b) of this Agreement indicates that the Debt Coverage Ratio at the time of
calculation is less than 130%, then for each Quarterly Period then in effect or
thereafter occurring, after all amounts of Source of Debt Service required to
paid into the Debt Service Account and the Regular Reserve Account pursuant to
Sections 9.1 and 9.2 hereof with respect to such Quarterly Period have been so
paid, the Borrower shall pay into the Debt Coverage Reserve Account the entire
remaining amount of each payment of the Source of Debt Service, as and when
actually received by the Borrower.  Amounts deposited
<PAGE>   63
                                                                              58




and held in the Debt Coverage Reserve Account shall be applied as provided in
Section 3.5(b) hereof until the Debt Coverage Ratio shall equal or exceed 130%.
The procedure set forth in this Section 9.3 shall continue in effect in each
subsequent Quarterly Period until the Debt Coverage Ratio, calculated at the
commencement of any such Quarterly Period, equals or exceeds 130%.

                 9.4      Payments Made from Debt Service Account and Reserve
Account.  Except for any personal liability of the Borrower arising as
specifically provided in this Agreement and except for any prepayments pursuant
to Section 9.3 hereof, all payments to be made by the Borrower under this
Agreement, the Notes and the Letter Agreement, including in each case, without
limitation, payments due on the Final Maturity Date, shall be made only from
the Debt Service Account as at any applicable time the same shall be funded
under Sections 3.2 and 3.3 of the Trust Agreement; provided, however, that if
amounts held in the Debt Service Account and the Debt Coverage Reserve Account
are insufficient to pay all such amounts when due, any amounts then held in the
Regular Reserve Account shall be applied to make such payments to the extent
provided in Section 3.3 of the Trust Agreement.  Except in accordance with the
preceding sentence with respect to any personal liability of the Borrower, the
Borrower shall only be obligated to make payments under this Agreement, the
Notes and the Letter Agreement, including in each case, without limitation,
payments due on the Final Maturity Date, out of amounts of the Source of Debt
Service and Borrowed Amounts received by it.  The Borrower agrees that, as long
as moneys are held in such Debt Service Account and such sub-accounts of the
Reserve Account, the Lenders, to the extent necessary to make payments in
accordance with the terms of the Trust Agreement of principal, interest and
other amounts due under this Agreement, the Notes and the Letter Agreement, are
among those having a right as provided under Section 2.2 of the Trust Agreement
to receive disbursements thereunder.

                 9.5      No Recourse.  In furtherance of Sections 9.1 to 9.4
hereof, each of the Agent, the Arrangers, the Lenders and each holder of a
Note, by its acceptance thereof, agrees that, except as provided in Sections
9.3 and 9.4, (i) it will look solely to the Source of Debt Service and Borrowed
Amounts to the extent provided in Sections 9.3 and 9.4 hereof for all payments
to be made by the Borrower under this Agreement, the Notes and the Letter
Agreement, as provided therein or herein, including in each case, without
limitation, payments due on the Final Maturity Date, and that no recourse shall
be had for the payment of the principal of or interest on the Notes or the
payment of any other amounts due under this Agreement or the Letter Agreement,
or shall be had for any claim based on any provision hereof or thereof, against
Bank of America National Trust and Savings Association (or any entity acting as
successor trustee under the Trust Agreement), in its individual capacity, or
against any past, present or future stockholder, officer, director, employee or
agent of Bank of America National Trust and Savings Association (or any entity
so acting), or against
<PAGE>   64
                                                                              59




the grantors, settlors or beneficiaries of any trust under the Trust Agreement,
either directly or through the Borrower or any successor of any thereof, under
any constitution, statute or rule of law or by the enforcement of any
assessment, or otherwise, and (ii) neither Bank of America National Trust and
Savings Association (or any such entity acting as such successor trustee), nor
any such other Person shall have any personal obligation, liability or duty
whatsoever to the Agent, the Arrangers, the Co-Agents or the Lenders or any
holders of the Notes or anyone else for or with respect to any such payment or
for the performance of or compliance with any covenant or agreement contained
in any of said documents or for the truth, accuracy or completeness of any
statement or representation made in any such document, except only in the case
of Bank of America National Trust and Savings Association (or any such entity
acting as successor trustee), for any material breach of a representation or
warranty expressly made by it under Section 4 or Section 5.2 hereof in its
individual capacity and such liability as may arise under this Agreement for
gross negligence or willful misconduct in acting hereunder.  In such connection
the Borrower (a) shall be entitled to act upon any notice, certificate,
request, direction, waiver, receipt or other document which it in good faith
believes to be genuine and it shall be entitled to rely upon the due execution,
validity and effectiveness of, and the truth and acceptability of any
provisions contained in, any of the foregoing so received, (b) may consult
with, and obtain advice from qualified accounting and legal advisers in
connection with the performance of its obligations and it shall incur no
liability and shall be fully protected in acting in good faith in accordance
with the opinion and advice of such advisers, and (c) shall have no duties
other than those specifically set forth or provided for herein nor any
obligation to familiarize itself with nor any responsibility with respect to
any other agreement relating to the transactions contemplated by this Agreement
to which it is not a party.

                 9.6      Not to Limit Remedies.  Nothing contained in this
Section 9 shall be construed to limit the exercise and enforcement, in
accordance with the terms of this Agreement, the Notes or the Letter Agreement,
of the rights and remedies of the Agent, the Arrangers, the Co-Agents or the
Lenders or any holders of the Notes against the Borrower hereunder to the
extent of the Source of Debt Service and Borrowed Amounts as provided herein.

single or partial exercise of any right, power or privilege hereunder preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege.  Subject always to the provisions of Section 9 hereof, the rights
and remedies herein provided shall be cumulative and not exclusive of any
rights or remedies provided by law.  The provisions of this Agreement shall
inure to the benefit of any subsequent holder of the Notes.

                 10.3     Use of English Language.  All documents or notices to
be delivered pursuant to or in connection with this Agreement shall be in the
English language.  English shall be the official language for construction and

                 10.4     Assignment; Successors and Assigns; Participations.

                          (a)     This Agreement shall be binding upon and
inure to the benefit of the Borrower, the Arrangers, the Lenders, the Agent,
the Co-Agents and their respective successors and permitted assigns.  The
Borrower may not assign any of its rights or delegate any of its obligations
hereunder without the written consent of all of the Lenders.  Any Lender may at
any time sell, assign, transfer, negotiate, or otherwise dispose of, in whole
or in part, with the prior written consent (such consent not to be unreasonably
withheld) of the Borrower, its rights and obligations under this Agreement or
the Notes; provided, that such consent by the Borrower shall not be required
for any proposed sale, assignment, transfer, negotiation or other disposition
by a Lender (other than the Finance Company) to another financial institution
(i) at least 75% of the voting shares of which are held directly or indirectly
by such Lender, or (ii) holding directly or indirectly at least 75% of the
voting shares of such Lender or (iii) at least 75% of the voting shares of
which are held directly or indirectly by a corporation which holds directly or
indirectly at least 75% of the voting shares of such Lender (any of the
foregoing described transferees, a "Section 10.4(a) Affiliate").  The exercise
of such right by any Lender is, however, subject to the conditions that the
transferee shall (x) not have any right at the time of transfer, or shall have
effectively waived any right existing in the transferee at the time of
transfer, pursuant to Section 3.3 hereof to claim from the Borrower tax
indemnification and pursuant to Section 3.4(b) hereof to claim from the
Borrower any additional amounts, in either case above and beyond that or those
which could have been claimed by the transferor at the time of transfer, (y)
not have any right at the time of transfer pursuant to Section 3.4(a) hereof
not possessed by the transferor at the time of transfer, and (z) in the case of
any transfer to a Section 10.4(a) Affiliate, not have designated a Lending
Office in any jurisdiction with respect to which the Borrower is at the time of
transfer prohibited by applicable state or federal laws of the United States
from doing business.

                          (b)     In furtherance of the foregoing clause (a),
any Lender wishing to transfer any of its rights and obligations under this
Agreement or the Notes to any Person shall effect such transfer in the
following manner:

                                     (i)   The Lender and the Person or Persons
to which the Lender wishes to transfer any of such rights and obligations (the
"Transferee" or "Transferees") shall duly complete and execute a transfer
certificate in the form of Exhibit C-2 hereto (the "Transfer Certificate").

                                     (ii)  Unless the intended Transferee is
stated in the relevant Transfer Certificate to be a Section 10.4(a) Affiliate,
the Lender shall obtain the consent of the Borrower to the transfer by having
the Borrower evidence its consent in the space provided therefor in the
Transfer Certificate.

                                    (iii)  The Lender then and only then shall
deliver the Transfer Certificate to the Agent together with (x) a photocopy of
the Transfer Certificate as executed by the Lender, the Transferee and the
Borrower, (y) the Note or Notes in respect of which the transfer is being made,
and (z) payment by the Transferee or the Lender of the transfer fee of $3,500,
upon receipt of which the Agent shall acknowledge receipt of such Transfer
Certificate in the space provided therefor in the photocopy and deliver the
same to the Transferee.

                                     (iv)  Each transfer shall become effective
on the later of (x) the date specified for such transfer in the related
Transfer Certificate and (y) the fifth Business Day after acknowledgment of
receipt of the related Transfer Certificate by the Agent.

                                     (v)   Upon a transfer becoming effective
in the foregoing manner, the Transferee shall assume the obligations and
acquire the rights which are the subject of such transfer with the same effect
as if such Transferee had been an original party hereto as a Lender with the
rights and obligations acquired and assumed by such Transferee as the result of
such transfer.

                          (c)     The Agent shall as promptly as practicable
deliver to the Borrower a copy of each Transfer Certificate the receipt of
which is acknowledged pursuant to this Section 10.4 together with the Note or
Notes received with respect thereto, whereupon the Borrower shall execute and
deliver into the custody of the Agent one or more new Notes (dated the date to
which interest has been paid on the Advances evidenced thereby) (i) in the
principal amounts being retained, if any, and/or transferred by the transferor
and the Transferee or Transferees, respectively, (ii) payable to the order of
such transferor and/or Transferee or Transferees, respectively, and (iii) in an
aggregate principal amount equal to that evidenced by the Note or Notes which
are the subject of such transfer.

                          (d)     The Agent shall as promptly as practicable
deliver to the relevant Transferees all new Notes delivered into its custody
pursuant to Section 10.4(c) hereof.

                          (e)     The Agent and the Borrower may treat each
Lender as the holder of the Note drawn to its order and delivered to such
Lender, whether pursuant to Section 2.8 hereof or this Section 10.4, except in
those circumstances where a transfer has become effective pursuant to this
Section 10.4 but the new Note or Notes to be issued in connection with such
transfer have yet to be issued, in which case the transferor and Transferee or
Transferees parties to such transfer shall be treated as the holder or holders
of the existing Note or Notes related to such transfer to the extent of their
respective interests as set forth in the relevant Transfer Certificate.

                          (f)     All agreements, representations and
warranties made herein shall survive the making of any such transfer hereunder
by any Lender.

                          (g)     Notwithstanding anything otherwise contained
in this Section 10.4, each Lender may grant participations which do not create
or purport to create binding obligations of the Borrower, in whole or in part,
in its rights under this Agreement and the Notes without any restriction and
without notice to the Borrower.

                 10.5     Amendments.  Any provision of this Agreement or the
Notes may be amended or waived if, and only if, such amendment or waiver shall
be in writing and signed by the Majority Lenders and, if the Agent's rights or
duties as agent are affected, the Agent; provided that any such amendment must
also be signed by the Borrower; and provided, further, that no such amendment
or waiver shall, unless signed by each Lender, do any of the following:  (a)
increase or decrease the Commitment of any Lender or subject any Lender to any
additional obligation hereunder; (b) reduce the amount or postpone the date of
any payment of principal, interest or other amount hereunder; (c) reduce the
percentage of the amount of the Commitments or the Advances specified in the
definition of "Majority Lenders" or otherwise required to take any action
hereunder; or (d) amend or waive any provision of this Section 10.5.  Any such
amendment or waiver shall be signed by the Agent on behalf of the relevant
Lenders if the Agent has been so authorized in writing or by telex, cable or
facsimile transmission by the Majority Lenders or all of the Lenders, as the
case may be.  Any amendment or waiver signed by the Agent in accordance with
the preceding sentence shall be binding upon the Lenders and any holder of a
Note.  Any action that the Agent may take on behalf of the Majority Lenders
under this Agreement and that the Agent in fact so takes shall be binding on
all of the Lenders.

                 10.6     Expenses; Indemnification.

                          (a)     Subject to such limitations as are separately
agreed, whether or not the transactions contemplated by this Agreement shall be
consummated, the Borrower agrees (i) to pay, or reimburse the Agent, on behalf
of the Lenders, for, all reasonable fees, disbursements, expenses (including
without limitation travel expenses) and other charges of the Lenders' special
New York, Taiwanese and Korean counsel and (ii) to pay, or reimburse the Agent,
on behalf of the Arrangers, for, all other reasonable out-of-pocket expenses of
the Arrangers, including, but not limited to, travel and photocopying expenses,
in each case in connection with the preparation, negotiation and signing of the
documents related to the transactions contemplated by, the preparation by the
Lenders of an information memorandum with respect to, and the satisfaction of
the conditions precedent for the initial disbursement under, this Agreement;
provided that, subject to Section 10.6(b) hereof, the Borrower shall not be
obligated to pay or reimburse the Lenders for any such fees, disbursements,
expenses or other charges that were incurred prior to October 14, 1996 or after
the initial Borrowing Date, unless such fees, disbursements, expenses or other
charges were incurred pursuant to reasonable and customary post-closing
activities immediately after the initial Borrowing Date.  With respect to such
amounts for which invoices shall have been delivered to the Borrower (i) on or
prior to February 14, 1997, the Borrower shall pay such amounts on or before
the earliest to occur of (x) the initial Borrowing Date, and (y) the 30th day
following the Effective Date and (ii) at any time after February 14, 1997, the
Borrower shall pay such amounts on or before the next date that is the 21st day
of a month and occurs at least 30 days following the date of delivery to the
Borrower of such invoice.

                          (b)     The Borrower agrees (i) to pay, or reimburse
the Agent for, all reasonable out-of- pocket expenses, including, but not
limited to, travel expenses, legal fees, disbursements and other charges of
Lenders' counsel incurred by the Agent in connection with any amendment or
supplement to, or modification or waiver of, this Agreement, the Trust
Agreement, the Producers Agreement or other related documents after this
Agreement has been fully executed, and (ii) whether or not amounts due under
this Agreement, any of the Notes or the Letter Agreement are accelerated, upon
the occurrence of an Event of Default or an event the occurrence or
nonoccurrence of which would, with notice or lapse of time or both constitute
an Event of Default (but only if such event later becomes an Event of Default),
to pay, or reimburse the Agent for, all reasonable out-of-pocket expenses of
the Agent and each holder of any Note arising in connection with such Event of
Default or the enforcement of this Agreement, such Note, the Letter Agreement
or the Producers Agreement, including but not limited to the fees,
disbursements and expenses (including without limitation travel expenses) and
other charges of counsel employed by the Agent or such holder.  The Borrower
shall pay any such amounts for which an invoice is delivered to it prior to the
Completion Date, on or before the earlier of (A) the 30th day following
<PAGE>   70
                                                                              65




the next Borrowing Date and (B) the 60th day following the date of delivery to
the Borrower of the invoice therefor.  The Borrower shall pay any such amounts
for which an invoice is delivered to it on or after the Completion Date as
provided in the Trust Agreement.

                 10.7     Sharing of Set-Off and Other Payments.  In the event
that any Lender shall have received an amount in excess of its ratable share of
payments hereunder or under the Notes through the exercise of any lien, set-off
or similar right or any voluntary payment by the Borrower, such Lender shall
promptly (and in any event within 15 days) purchase for cash, without recourse
that portion of each other Lender's Advances as will result in each Lender
receiving its ratable share of the amount of such lien, set-off or similar
right, or voluntary payment; provided that to the extent that such excess
amount or any portion thereof is subsequently recovered from the purchasing
Lender, its purchases from the other Lenders shall be rescinded and the price
repaid without interest; and provided further, that if, after acceleration of
the maturity of the relevant Notes pursuant to Section 7 hereof, any Lender
shall commence an action or proceeding in any court to enforce the relevant
Notes held by such Lender and as a result thereof, or in connection therewith,
shall receive an excess payment on such Notes, such Lender shall not be
required to share any portion of such excess payment with a Lender which has
received sufficient notice to enable it to and which, has the legal right to,
but does not, join such action or proceeding or commence and diligently
prosecute a separate action or proceeding to enforce its Notes in another
court.  Nothing herein contained shall in any way affect (a) expenses pursuant
to Section 2.6(b) hereof, prepayments pursuant to Section 3.4 hereof and
interest payments calculated in accordance with the provisions of the fifth
sentence of Section 2.5 hereof and (b) the right of any Lender to obtain
payment of indebtedness of the Borrower other than Indebtedness under this
Agreement, the Notes and the Letter Agreement.

                 10.8     Counterparts.  This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts together shall constitute one and the same
instrument.  Complete sets of counterparts shall be lodged with the Agent and
the Borrower.

                 10.9     Table of Contents and Section Headings.  The table of

commence on the date hereof and shall end on the termination of all of the
Lenders' Commitments or payment in full of all of the Notes and all other
amounts payable under this Agreement and the Letter Agreement, whichever is

to Sections 3 and 10.6 of this Agreement shall survive the repayment of the
Advances and the cancellation of all of the Notes until all amounts payable
thereunder are paid in full.

Agreement), approvals and communications necessary or appropriate in order (x)
to effect Borrowings, repayments and payments by the Trustee as Borrower under

Production Sharing Contracts, the Supply Agreements, the LNG Sales Contracts,
the Transportation Agreement, any Other Transportation Agreement and any other

either LNG Sales Contract, except in respects which are not material and not
likely to give rise to the assertion of a claim for breach thereunder, and to
perform in all material respects the terms of the other Basic Agreements to
which it is a party, as the same may be modified or amended from time to time
as permitted by Section 1.4 hereof.

                    1.6   Enforcement of Agreements.  The Producers agree that,
if the Borrower shall fail to perform any of its obligations under the Trust
Agreement, then the Producers shall give written notice to the Borrower as

promptly enforce all legal rights it possesses against the Borrower to compel
performance by the Borrower of its obligations under the Trust Agreement, and
give notices from time to time to the Agent with respect to the actions being
taken.  Each of the Producers that is a party thereto shall, with due diligence
and in a reasonable and prudent manner, enforce its rights (a) under the EPC

Borrower, Bank of America National Trust and Savings Association or any
successor trustee under the Trust Agreement to enter into the Trust Agreement,
or to serve thereunder in accordance with the terms thereof or to perform any
material obligation thereunder, or in the case of the Borrower, to enter into
the Loan Agreement or to perform any material obligation thereunder.

                    1.9   Indebtedness; Permitted Amounts.  The Producers shall
neither enter into, nor authorize or request the Borrower or any other Person
to enter into, financing agreements or otherwise create, assume or become
liable for, directly or indirectly, any Indebtedness pursuant to any agreement

appropriate "All Risk" Builder's Risk Insurance with respect to the work to be
performed in connection with the Debottlenecking Project.

                          (b)     Pertamina shall maintain, or cause to be
maintained with respect to the Insured Bontang Plant, property and casualty
insurance (the "Plant Insurance") on terms at least as favorable to Pertamina
as, and having coverage substantially similar to, the policy furnished to the
Agent prior to the date hereof and in an amount which is the greater of (i) the
sum of (w) the full replacement value of the Insured Bontang Plant, together
with spare parts located within the perimeter fences thereof, and (x) the
maximum value of the inventory forming a part of the Insured Bontang Plant,
determined on the basis of an independent appraisal provided in the manner
described below in this Section 1.11(b) (if such Plant Insurance in such amount
is available on commercially reasonable terms); provided, however, that upon
completion of the Train G Additional Plant of the Bontang Plant and until such
time thereafter as a new independent appraisal of the Insured Bontang Plant is
completed, the amount determined in accordance with this clause (i) shall be
increased by the total cost of the construction, installation and completion of
such Train G Additional Plant, excluding the cost of the items excluded from
the determination of the full replacement value of the Insured Bontang Plant in
the next succeeding sentence or (ii) 125% of the sum of (y) all amounts
outstanding from time to time under the Loan Agreement, the Notes and the
Letter Agreement, plus (z) all other Indebtedness of any Person outstanding,
the holders of which, directly or indirectly, are entitled to share in the
proceeds of the Plant Insurance (the "Plant Insurance Proceeds") prior to or on
an equal and ratable basis with the Lenders (as the Lenders' rights are
determined under Section 4.2 hereof).  In determining the full replacement
value of the Insured Bontang Plant pursuant to clause (i) above, the cost of
the following shall be excluded:  all basic engineering and that part of the
detail engineering that may be based on existing drawings and available
specifications, all dredging work, water wells, all major excavation work and
the use of heavy earth-moving equipment, and surplus materials in excess of
five percent (5%) of required quantities.  As of the date hereof, the appraisal
of the Insured Bontang Plant contemplated above shall be the appraisal dated
February 1994 prepared by RDI Consultants which has been delivered to the Agent
prior to the date hereof.  Thereafter, the appraisal of the Insured Bontang
Plant contemplated above shall be the independent appraisal most recently
prepared with respect thereto, including any of the following:  (1) upon the
written request of the Agent, Pertamina shall promptly cause to be prepared and
delivered to the Agent an appraisal prepared by an independent appraiser, who
shall be acceptable to the Agent in its reasonable judgment; provided, however,
that the Agent may not request Pertamina to cause any such appraisal to be
prepared and delivered more than once every five years, and (2) the Agent may
from time to time have prepared for its benefit and at the sole cost of the
Lenders an appraisal of an independent appraiser, who shall be acceptable to
the





                                       11

Producers in their reasonable judgment, and Pertamina shall, and shall cause
P.T. Badak to, cooperate reasonably in the preparation of such appraisal.

                          (c)     All Plant Insurance shall be maintained with
(i) P.T. Tugu Pratama Indonesia, or (ii) so long as Indonesian law requires
that the relevant insurance be maintained with an Indonesian insurance company,
any Indonesian insurance company other than P.T. Tugu Pratama Indonesia
approved by the Majority Lenders, which approval shall not be unreasonably
withheld, or (iii) if Indonesian law changes to permit the relevant insurance
to be maintained with one or more non-Indonesian insurance companies, any
insurance company other than P.T. Tugu Pratama Indonesia approved by the
Majority Lenders.

                          (d)     Pertamina agrees that all Plant Insurance
shall have Pertamina as a loss payee, and that no party other than Pertamina,
the other Producers and P.T. Badak shall be a loss payee.  Pertamina agrees
that it will not create or agree to any assignment of or security interest in
the Plant Insurance Proceeds, or create any right to receive the Plant
Insurance Proceeds other than equally and ratably with, or subordinated in
right of payment to, the rights of the Lenders pursuant to this Agreement in
favor of any Person other than the loss payees under the Plant Insurance.

                          (e)     Pertamina shall, on or before the Effective
Date, provide to the Agent a correct and complete copy of the policy or
policies of insurance required by Sections 1.11(a) and (b) hereof or other
evidence of such insurance, satisfactory to the Agent in its sole discretion
and, as promptly as practicable in the circumstances (but in no event later
than 30 days) following the issuance thereof, correct and complete copies of
each subsequent policy or policies of insurance required by Sections 1.11(a)
and (b) hereof.  Pertamina shall also provide to the Agent as promptly as
practicable under the circumstances, correct and complete copies of each
amendment, modification or waiver and each notice of cancellation or
termination with respect to each policy of insurance required by Sections
1.11(a) and (b) hereof (but in no event later than 30 days following any such
amendment, modification or waiver or receipt of any such notice).

                    1.12  Reserve Reports.

                          (a)     The Producers agree that, if requested by the
Agent, they will cause to be delivered to the Agent correct and complete copies
of the latest reserve report or reports and any updates, modifications or
supplements thereto covering the areas that supply gas to the Bontang Plant
(the "Gas Supply Area"), prepared by DeGolyer and MacNaughton or another
independent petroleum engineering consulting firm of recognized standing in the
petroleum industry qualified by reputation and experience in the estimating of
reserves of oil and gas in subsurface reservoirs.

                          (b)     Pertamina shall, before committing additional
natural gas from the Gas Supply Area for sale or other utilization, submit or
cause to be submitted to the Agent a copy of each certificate and all
supporting documentation furnished to the respective Buyer pursuant to Section
3.2(a) of the KGC Sales Contract or pursuant to Section 3.2(a) of the CPC Sales
Contract, together with a statement setting forth the calculation of the
Seller's Gas Supply Obligation (as defined in each LNG Sales Contract) and the
breakdown of such calculation by non-spot sale LNG sales contract, which
statement shall be in the form of that delivered to the Agent pursuant to
Section 5.1(a)(xvi) of the Loan Agreement.

                    1.13  Use of Proceeds.

                          (a)     The proceeds of the Borrowings shall be used
solely for the payment of (i) the costs incurred or to be incurred in
connection with or otherwise relating to the design, engineering, procurement
and construction of or otherwise relating to the Additional Plant, the Other
Facilities and, in the case of Borrowings that the Drawdown Schedule
contemplates for such purpose (but solely to the extent so contemplated), the
Support Facilities, (ii) interest, fees, expenses, taxes and other amounts
payable by the Borrower pursuant to Sections 2.3, 2.6, 2.7, 3.3, 3.4(b), 6.6
and 10.6 of the Loan Agreement and (iii) funding the Reserve Account as
provided in and solely to the extent permitted by Section 2.2(b) of the Loan
Agreement.

                          (b)     If, during the Availability Period after the
start of the Amortization Period, no further amounts of the Commitments of the
Lenders are available to be drawn by the Borrower under the Loan Agreement, and
if the proceeds of the Borrowings are insufficient to pay the costs required
for the completion of the Additional Plant and the Other Facilities as
indicated in the most recent quarterly status report delivered to the Agent
pursuant to Section 1.14(b) hereof, then, from time to time prior to the last
day of the Availability Period, the Producers may, to pay for such required
costs, instruct the Trustee to transfer to the Bontang VI Payment Account from
the amounts then held in the Regular Reserve Account, subject to Section
3.3(b)(iii) of the Trust Agreement, amounts which shall not exceed in the
aggregate the lesser of (x) the portion of the Reserve Account Borrowed Amount
that, pursuant to Section 6.1(h) of the Loan Agreement, is available to be used
to pay for such costs or (y) the amounts needed to pay for such required costs.
Any such instruction shall be provided by written notice to the Trustee and the
Agent.  The Producers shall use such amounts so transferred to the Bontang VI
Payment Account solely for the purpose of paying for such required costs.

                          (c)     If, following the first day of the
Amortization Period, the Producers shall at any time have paid the cost of a
Selected Qualified Bank retained and performing services pursuant to Section
6.6 of the Loan Agreement, then Pertamina





                                       13
<PAGE>   17


                          

may instruct the Bontang VI Trustee to transfer to the Bontang VI Payment
Account from the amounts then held in the Regular Reserve Account, subject to
the conditions contained in Section 3.3(b)(iv) of the Trust Agreement, an
amount which shall not exceed the amount so paid to such Selected Qualified
Bank.  Pertamina shall give any such instruction by giving notice to the
Trustee and the Agent setting forth the amount paid to the Selected Qualified
Bank and attaching a copy of the Selected Qualified Bank's invoice relating to
the services so performed.

                    1.14  Construction of Train H.

                          (b)     Pertamina shall deliver to the Agent (i) a
quarterly status report in reasonable detail concerning construction of Train
H, such report to include, but not be limited to, the cost incurred to the end
of such quarter and an estimate of costs required for the completion and
acceptance of Train H pursuant to the Development Plan and the EPC Contract,
and (ii) such other information in respect of Train H as the Agent may
reasonably request.

                          (c)     Pertamina shall submit or cause to be
submitted to the Agent a semi-annual report for each semi-annual period ending
on March 31 (other than March 31, 1997) and September 30, prepared by the
Engineering Firm or if the Engineering Firm becomes unacceptable to Pertamina
or to the Agent for any reason following the date hereof, any other independent
engineering firm of recognized standing in the construction industry and
acceptable to the Agent, concerning the status of the construction of Train H.
Such report shall be based upon the reports delivered pursuant to Section
1.14(b) hereof and such discussions and analysis thereof with representatives
of Pertamina, the EPC Contractor and the Sub-Contractor as the independent
engineering firm deems appropriate in order for the semi-annual report to
provide, through the end of such semi-annual period, a comparison of (i) the
physical progress of the construction of Train H with the progress scheduled
for such period and (ii) the expenditures made to achieve such physical
progress with the amounts forecast therefor.

                          (d)     Pertamina shall not amend the Development
Plan in a manner that would result in a material increase in Pertamina's
expenditures or materially deviate from the Development Plan with regard to the
construction, completion or operation of Train H; provided, however, that
Pertamina may, to the extent necessary to comply with the provisions of Section
1.18 hereof, deviate from the Development Plan by declining to construct
specific portions of the Support Facilities.

permit representatives of the Agent, and designees appointed by it with the
consent of Pertamina, which consent shall not be unreasonably withheld, to
visit the site of the construction of Train H to review and examine the current
status of the construction and implementation thereof.

                          (f)     Pertamina shall promptly after it becomes
aware of such event, give notice to the Agent of any event or occurrence that
will, or would be reasonably likely to, (i) prevent the shipment of LNG under
the KGC Sales Contract or the CPC Sales Contract from occurring during the
first calendar quarter of 2000 or (ii) prevent shipments of such LNG from
occurring on a regular basis thereafter.

                          (b)     Pertamina shall give notice to the Agent
promptly after it learns (i) of any event or occurrence, in the nature of force
majeure, and any material dispute that could reasonably be expected to affect
adversely the amount or time of receipt of the Source of Debt Service and (ii)
that any default under an LNG Sales Contract has occurred or will occur with
the giving of notice or lapse of time or both.  Pertamina shall thereafter also
inform the Agent of the status of such event at reasonable intervals during the
continuance thereof.

               1.16       Effect of Certain Events with Respect to LNG Sales
Contracts.

                          (a)     If (i) an LNG Sales Contract is terminated or
(ii) any sales under an LNG Sales Contract, which if made would give rise to
Source of Debt Service, are suspended in respect of any Buyer or Buyers or an
event of "force majeure" (as such concept is defined in such LNG Sales
Contract) as to any LNG tanker or any Buyer's facilities relevant to such LNG
Sales Contract shall occur and such suspension of sales or event of force
majeure shall continue for a period of nine (9) months, Pertamina shall make
all reasonable efforts to sell any LNG originally scheduled to be sold to any
affected Buyer or Buyers pursuant to such LNG Sales Contract after the date of
termination or the end of such nine-month period, as the case may be, which
Pertamina reasonably anticipates will not be sold because of such termination,
suspension of sales or event of force majeure; provided, however, that with
respect to an event of the type specified in the foregoing clause (ii),
Pertamina shall not be obligated to enter into any replacement LNG sales
contract which





                                       15
<PAGE>   19


                          

Pertamina reasonably anticipates would (x) cause it to be unable to perform
fully its obligations under the affected LNG Sales Contract upon the cessation
of such event of force majeure or suspension of sales or (y) otherwise be in
violation of such LNG Contract; and provided further that Pertamina may, in its
sole discretion, make replacement sales during any initial period of nine
months during which sales are so suspended or during which such an event of
force majeure has occurred.

                          (b)     Pertamina shall cause the proceeds of any
replacement sales made pursuant to Section 1.16(a) hereof to be paid to the
Trustee as if such sales had been made pursuant to the affected LNG Sales
Contract and shall authorize and request the Borrower to execute and deliver
prior to the payment of any such proceeds an agreement providing for any
amendment of the definitions of Source of Debt Service and Gross Invoice Amount
contained in the Loan Agreement and the Trust Agreement required to cause such
proceeds to be included therein.

                    1.17  Payment Instructions.

                          (a)     Subject to Section 1.8 hereof, Pertamina
hereby agrees to instruct each Buyer to pay to the Trustee all amounts payable
by such Buyer to Pertamina pursuant to the LNG Sales Contracts which constitute
Source of Debt Service, and not to change such instructions or the designation
of the Trustee as the recipient of amounts which constitute the Source of Debt
Service.

                          (b)     Subject to Section 1.8 hereof, Pertamina
agrees to deliver or to cause to be delivered to the Trustee on the date
payment is made to the Trustee pursuant to Section 1.17(a), a written statement
correctly identifying the separate portions of such payment that relate to each
component of the Gross Invoice Amount and the Source of Debt Service and
specifying by category the portion of such payment that does not constitute
Source of Debt Service.  Such statement shall identify, among other things, the
portion of such payment related to (x) with respect to the KGC Sales Contract,
the Contract Sales Price (as defined in such contract) (or if such contract is
modified to provide, in whole or in part, for ex-ship delivery of LNG, the
portion of the sales price not related to transportation) and (y) with respect
to the CPC Sales Contract, the LNG Element (as defined in such contract).

                          (c)     With respect to all other relevant Basic
Agreements, Pertamina has designated or shall designate, and agrees not to
change the designation of, the Trustee as the recipient of amounts which
constitute the Source of Debt Service payable thereunder.

                          (d)     On or promptly following the date hereof, the
Producers shall instruct the Bontang III Trustee, the Bontang Excess Sales
Trustee and any other





                                       16
<PAGE>   20


                          

relevant trustee in writing to make immediate payment to the Bontang VI Trustee
of any amounts received by any of such trustees and deposited under the Bontang
III Trust Agreement, the Bontang Excess Sales Trust Agreement or any other
relevant trust agreement or trustee and paying agent agreement which constitute
Source of Debt Service as defined in the Loan Agreement.  The Producers shall
provide copies of such written instruction (which may be reflected in an
amendment to the relevant trust agreements or trustee and paying agent
agreements) to the Agent simultaneously with sending such instructions to the
Bontang III Trustee, the Bontang Excess Sales Trustee and any other relevant
trustee.  The Producers agree that, so long as any amounts remain owing to the
Lenders under the Loan Agreement, the Notes or the Letter Agreement, such
written instruction shall not be revoked, amended or modified, except with the
prior written consent of the Majority Lenders.

                    1.18  Monitoring Total Project Expenditures.

                          (a)     Pertamina hereby agrees that, during the
Availability Period, it will monitor Borrowings, interest rate(s) applicable to
the Notes and all other costs and expenditures relating to Train H on a
quarterly basis and in accordance with its customary procurement procedures, in
order to determine the extent to which the costs of specific portions of the
Support Facilities can be financed through Borrowings under the Loan Agreement
without causing the sum of (i) all reasonably anticipated costs of completing
the Additional Plant and the Other Facilities that have not already been paid
for from the proceeds of previous Advances, plus (ii) all reasonably
anticipated costs of such specific portions of the Support Facilities that
Pertamina proposes to finance through Borrowings under the Loan Agreement, plus
(iii) all reasonably anticipated future Borrowed Amounts, to exceed the then
remaining Commitments.  If and to the extent that at any time the Drawdown
Schedule does not provide for the financing of the costs of any specific
portions of the Support Facilities and such costs can be so financed without
causing such sum to exceed the then remaining Commitments, and if, after
financing such costs the remaining Commitments will be sufficient to fund fully
the amounts referred to in clauses (i), (ii) and (iii) above, then Pertamina
may instruct the Borrower to revise the current Drawdown Schedule to provide
for the financing of the costs of such specific portions of the Support
Facilities through Borrowings under the Loan Agreement.  If and to the extent
that at any time the costs of any specific portions of the Support Facilities
cannot be so financed as provided in the first sentence hereof, then Pertamina
shall instruct the Borrower to revise the then current Drawdown Schedule to
exclude such financing.

                          (b)     Pertamina shall submit, or cause to be
submitted to the Agent, with reasonable promptness after the end of each
semi-annual period ending on March 31 (other than March 31, 1997) or September
30 during the Availability Period, a summary statement of its then current
estimate of the excess capacity of the Bontang





                                       17
<PAGE>   21

                          

Plant to be contractually uncommitted on January 1, 2000, excluding the LNG
Sales Contracts and the capacity of the Additional Plant.

                    1.19  Debt Service Accounts.  Each of the Producers agrees
with respect to the Trust Agreement that, as long as moneys are held by the
Trustee in the Debt Service Account and Reserve Account, the Lenders are, to
the extent necessary for payments to be made in accordance with the terms of
the Trust Agreement of principal, interest and other amounts due under the Loan
Agreement, the Notes and the Letter Agreement, among those having a right, as
provided under Section 2.2 of the Trust Agreement, to receive disbursements
thereunder.

                    1.20  Expenses.  To the extent that any amounts required to
be paid by the Borrower pursuant to Section 10.6(a) and, prior to the
Completion Date, Section 10.6(b), of the Loan Agreement are not paid when due,
the Producers shall, following notice from the Agent, immediately pay such
amounts or otherwise cause such amounts to be paid.

                    1.21  Financial Statements.  Upon the request of the Agent,
from time to time, each Producer agrees to deliver to the Agent in respect of
one or more fiscal years (but no more than the three immediately prior fiscal
years) of such Producer or, where applicable, of any Person controlling such
Producer which reports its financial condition and results to the public, any
publicly available annual financial statements of such Producer or Person.

                                     PART 2

                         REPRESENTATIONS AND WARRANTIES


                    Each Producer makes the following representations and
warranties to the Lenders solely with respect to itself; provided, however,
that (i) each representation and warranty with respect to any agreement that is
dated on, as of or prior to the date hereof is made as of the date hereof, (ii)
each representation and warranty with respect to any other agreement will be
made as of the date such agreement is entered into and solely with respect to
the agreement being entered into as of such date, (iii) each representation and
warranty with respect to any agreement is made only by those Producers that are
parties thereto and (iv) Pertamina is the only Producer making the
representation and warranty in Section 2.9 hereof:





                                       18

                    2.1   Due Incorporation; Power and Authority.  Such
Producer is a corporation or partnership duly organized and validly existing
under the laws of the jurisdiction of its incorporation or formation.  Such
Producer has, and upon the due  execution and delivery of any such agreement
not heretofore executed and delivered will have, full power, authority and
legal right to execute, deliver, perform and observe the terms and provisions
of this Agreement, the Trust Agreement, each Production Sharing Contract, the
EPC Contract, the Transportation Agreement, any Other Transportation Agreement
and each Basic Agreement.

                    2.2   Legal Action.  All necessary legal action has been
taken, and upon the due execution and delivery of any such agreement not
heretofore executed and delivered will have been taken, to authorize such
Producer to execute and deliver and to perform and observe the terms and
provisions of this Agreement, the Trust Agreement, each Production Sharing
Contract, the EPC Contract, the Transportation Agreement, any Other
Transportation Agreement and each Basic Agreement.

                    2.3   Restrictions.  There is no Legal Requirement and no
contractual or other obligation binding on such Producer, and upon the due
execution and delivery of any such agreement not heretofore executed and
delivered there will be no Legal Requirement and no contractual or other
obligation binding on such Producer, including, without limitation, under any
of the Basic Agreements or the Production Sharing Contracts or the EPC
Contract, the Transportation Agreement or any Other Transportation Agreement,
that is or will be contravened (or, in the case of a contractual obligation, in
respect of which a breach has occurred or will occur) by reason of the
execution and delivery of or the performance or observance by such Producer of
any of the terms or provisions of this Agreement or the Trust Agreement.

                    2.4   Registrations and Approvals.  No registrations,
declarations or filings with, or consents, licenses, approvals or
authorizations of, any legislative body, governmental department or government
authority are necessary or required under any applicable law for the due
execution and delivery by such Producer, or for the performance by such
Producer, of this Agreement or the Trust Agreement, or to assure the validity
or enforcement hereof or thereof with respect to such Producer, except such as
have been obtained, copies of which have been provided to the Agent in
connection with the execution and delivery of this Agreement and which remain
in full force and effect.

                    2.5   Agreement Binding; No Defaults.  This Agreement, the
Trust Agreement, each Production Sharing Contract and each Basic Agreement
constitute, and when duly executed and delivered, the EPC Contract, the
Transportation Agreement and each Other Transportation Agreement will

enforceable against it in accordance with each





                                       19
<PAGE>   23

                          

of their respective terms, subject in the case of enforcement to any applicable
bankruptcy, insolvency, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and to equitable principles of
general application.  No Default by such Producer has occurred and is
continuing and no event has occurred or failed to occur in each case pertaining
to such Producer, the occurrence or non-occurrence of which with the giving of
notice or lapse of time or both would constitute a Default.  Such Producer is
not, and upon the due execution and delivery of each of the Transportation
Agreement and each Other Transportation Agreement will not be, in violation of
any of such Producer's obligations under (i) the Trust Agreement, (ii) any of
the Production Sharing Contracts, the Supply Agreements, or the LNG Sales
Contracts, except for violations which are not material and are not likely to
give rise to the assertion of a claim for breach, (iii) any of the Basic
Agreements (other than those referred to in the immediately preceding clause
(ii)) or the EPC Contract, in any material respect.  Such Producer is not, and
upon execution and delivery of the EPC Contract will not be, in violation of
any of the Producer's obligations under (i) the Trust Agreement, (ii) any of
the Production Sharing Contracts, the Supply Agreements or the LNG Sales
Contracts, except for violations which are not material and are not likely to
give rise to the assertion of a claim for breach, (iii) any of the Basic
Agreements (other than those referred to in the immediately preceding clause
(ii)), in any material respect.  Each of the Production Sharing Contracts, the
Plant Use Agreement and the Processing Agreement either does not by its terms
terminate, or is not by its terms scheduled to expire, prior to the time of
shipment of the last cargo giving rise to Source of Debt Service under either
of the LNG Sales Contracts (except in the case of those Production Sharing
Contracts that are scheduled so to expire as provided in the relevant portion
of the definition of Production Sharing Contracts set forth in the Trust
Agreement), the Transportation Agreement, when executed and delivered will not
by its terms terminate or will not by its terms be scheduled to expire prior to
the time of shipment of the last cargo giving rise to Source of Debt Service
under the CPC Sales Contract, and each Supply Agreement either does not by its
terms terminate, or is not by its terms scheduled to expire, prior to the time
of shipment of the last cargo giving rise to Source of Debt Service under the
LNG Sales Contract to which such Supply Agreement relates.

                    2.6   Litigation.  There is no suit, action, proceeding or
investigation pending against such Producer or, to the best of such Producer's
knowledge, threatened against such Producer, which (a) questions the validity
of this Agreement, the Trust Agreement, the EPC Contract, any Production
Sharing Contract, the Transportation Agreement or any Basic Agreement, or any
material action taken or to be taken by such Producer pursuant hereto or
pursuant to any thereof, or (b) affects materially and adversely or is likely
materially and adversely to affect (i) the amounts of the Source of Debt
Service payable to the Trustee under either of the LNG Sales Contracts, or the
right of the Borrower to receive any such amounts under the Loan Agreement,
(ii) the





                                       20

Bontang Plant or Pertamina's interests therein or (iii) such Producer's ability
to perform its obligations under this Agreement, the Trust Agreement, the EPC
Contract, any Production Sharing Contract, the Transportation Agreement or any
Basic Agreement.

                    2.7   Compliance with Other Instruments, etc.  Such
Producer is not, and upon the due execution and delivery of each of the EPC
Contract, the Transportation Agreement and any Other Transportation Agreement
will not be, in violation of any term of its charter or by-laws or, as
relevant, the partnership agreement under which such Producer is formed, or any
term of any agreement or any instrument to which it is a party or by which it
or any of its properties is bound or any Legal Requirement, which violation
would have a material adverse effect on such Producer's ability to perform its
obligations under this Agreement, the Trust Agreement, any Production Sharing
Contract, the EPC Contract, the Transportation Agreement, any Other
Transportation Agreement or any Basic Agreement.

                    2.8   Other Agreements.  The Agent has been provided with
correct and complete copies of the Development Plan and the Basic Agreements,
in each case as amended and in effect on the date hereof.  The copies of the
EPC Contract (excluding the materials referred to in Exhibit A of the agreement
referred to in clause (i) of the definition of the EPC Contract), the
Transportation Agreement and each Other Transportation Agreement provided to
the Agent upon execution and delivery thereof will be correct and complete
copies of such agreements, in each case as amended and in effect on the date
thereof.  Each Producer represents and warrants that, to the best of its
knowledge, no party to any of such Production Sharing Contracts or the Basic
Agreements, other than any other Producer, is, and upon the due execution and
delivery of each of the EPC Contract, the Transportation Agreement and each
Other Transportation Agreement no party to each such agreement will be, in
breach of any material obligation thereunder.

                    2.9   Insurance.  As of the Effective Date, insurance
coverage of the type required by Section 1.11 hereof will be in full force and
effect, no default or breach shall exist thereunder which would give rise to a
right to cancel the same, and no notice of default or breach or notice of
termination shall have been given to Pertamina with respect thereto.  On or
prior to the Effective Date, correct and complete copies of such insurance
policies or other evidence of such insurance will be delivered to the Agent.

                    2.10  No Encumbrance.  There is no Encumbrance on the
Source of Debt Service prior to its deposit in the Bontang VI Payment Account
caused by such Producer, for which such Producer is responsible or which
relates to such Producer, except Encumbrances, if any, (i) arising pursuant to
statute or otherwise by operation of law, and not pursuant to any agreement,
which are not being enforced by attachment or levy and which will be discharged
in the ordinary course of business or (ii) permitted by Section 1.10 hereof.

                    2.11  No Material Adverse Change.  With respect to each
Producer, there has been no material adverse change since the date of the
financial statements delivered by such Producer to the Lead Arranger on or
prior to the Effective Date in (i) the business, assets, financial position or
results of operation of such Producer which affects materially and adversely,
or would be likely to affect materially and adversely, the performance by
Pertamina of or the ability of Pertamina to perform its obligations under the
LNG Sales Contracts or (ii) the operation of the Bontang Plant.


                                     PART 3

                                    DEFAULTS

                    3.1   Default Defined.  Each of the Producers agrees with
the Lenders that if any one or more of the following events shall occur it
shall be, so long as the same shall continue, a default hereunder (a
"Default"):

                          (a)     a failure to comply with any of the
provisions of Section 1.1, 1.3, 1.4, 1.9, 1.10, 1.11, 1.17 (other than
1.17(b)), 1.19 or 6.3 hereof; or

                          (b)     a failure to comply with any of the
provisions of Section 1.5, 1.6, 1.7, 1.14(f), 1.15(b), 1.16, 1.17(b), 1.18(a)
or 3.5 hereof for seven days after written notice of such failure shall have
been given to the Producers by the Agent; or

                          (c)     a failure to comply with any of the
provisions of Part 1 hereof other than those referred to in Sections 3.1(a) and
(b) hereof for 30 days after written notice of such failure shall have been
given to the Producers by the Agent; or

                          (d)     any representation or warranty made by any
Producer in this Agreement (including the representations contained in the
first paragraph following "Dear Sirs:" at the beginning of this Agreement)
shall prove to have been incorrect or misleading in any material respect as of
the date when made or deemed made; or





                                       22
<PAGE>   26

                          

                          (e)        (i)   failure by any of the Producers to
pay principal of, or premium or interest on, any of its Indebtedness in an
amount which is material in the context of this Agreement when due for payment,
whether by acceleration or otherwise, but after giving effect to all applicable
grace and waiver periods provided for in the agreement or instrument creating
or evidencing such Indebtedness; or

                                     (ii)  any of the Producers shall:

                                          (1)     make an assignment for the
         benefit of creditors; or

                                          (2)     file a petition in bankruptcy,
         petition or apply to any tribunal or applicable regulatory or
         governmental authority for the appointment of a custodian, receiver,
         trustee or official with similar powers for it or a substantial part
         of its property or assets, or commence any case or proceeding under
         any bankruptcy, reorganization, arrangement, readjustment of debt,
         dissolution or liquidation or similar law or statute of any
         jurisdiction, whether now or hereafter in effect; or

                                          (3)     if any such petition or
         application shall have been filed, or any such case or proceeding
         shall have been commenced against it, indicate its consent to,
         approval of or acquiescence in any such petition, application, case or
         proceeding or the appointment of a custodian, receiver, trustee or
         official with similar powers or regulatory or other governmental
         authority for it or any substantial part of its properties or assets,
         or suffer to exist any such case or proceeding in which an order for
         relief is entered, or suffer any such custodianship, receivership,
         trusteeship or jurisdiction of such official or regulatory or
         governmental authority to continue undischarged for a period of 60
         days or more; or

                                          (4)     generally be unable to or
         generally fail to pay its debts as such debts become due; or

                                     (iii)  a failure by P.T. Badak to comply
with a material term or provision of the Plant Use Agreement or the Processing
Agreement;

provided, however, that the effect of the occurrence of any of the events or
circumstances referred to in this clause (e) is to affect, materially and
adversely, the performance by Pertamina of its obligations under either of the
LNG Sales Contracts or the ability of Pertamina to perform such obligations; or





                                       23
<PAGE>   27

                                     

                          (f)     any statement furnished to the Agent under
any of Section 5.2(c) or 6.1 of the Loan Agreement with respect to the Debt
Coverage Ratio, the Gross Invoice Amount or the Source of Debt Service, as of
the date of such statement, (i) was not prepared based on information
concerning amounts outstanding under the Loan Agreement or the Notes which was
complete and accurate in all material respects or information concerning
amounts of the Gross Invoice Amount or the Source of Debt Service actually
invoiced or received which was complete and accurate in all material respects,
or (ii) was not prepared based on assumptions concerning future periods which
were established as provided in the Loan Agreement, or (iii) was delivered by
the Producers in bad faith or by the Borrower pursuant to a request or
authorization of the Producers given in bad faith.

                    3.2   Remedy for Default.  If at any time during one or
more Interest Periods the effect of any one or more Defaults is to cause the
Source of Debt Service received by the Borrower and payable to the Lenders to
be insufficient to satisfy any payment obligation when due under the Loan
Agreement, any of the Notes or the Letter Agreement (the difference between the
amount of the Source of Debt Service received with respect to any Interest
Period by the Borrower and payable to the Lenders under the Loan Agreement, any
of the Notes or the Letter Agreement and the amount which would have been so
received and payable but for such Default or Defaults, the "Default
Shortfall"), then each of the Producers which caused or is responsible for such
Default or to which such Default relates shall be obligated to pay an aggregate
amount to the Agent for the account of the Lenders, on the dates when due
during or at the end of such Interest Period, in the manner and with the effect
of payments made by the Borrower as provided in the Loan Agreement, the
relevant Notes or the Letter Agreement, on account of its Liability Share of
the Default Shortfall, such that the net aggregate amount received from each
such Producer by the Agent for the account of the Lenders pursuant to this
Section 3.2, after deduction of all Taxes required to be deducted or withheld
from, or otherwise paid by the Lenders with respect to, such payment (but
excluding Excluded Taxes required to be so deducted, withheld or paid solely to
the extent that the amount of such Excluded Taxes does not exceed the amount of
Excluded Taxes that would have been deducted, withheld or otherwise paid by the
Lenders, if there had been no Default Shortfall, and the net amount were paid
to, and received by, the Lenders out of the Source of Debt Service), shall
equal such Producer's Liability Share of the Default Shortfall.  The provisions
of this Section 3.2 shall apply to breaches of Section 1.17(b) as if such
breaches were a Default, whether or not notice of such breach is given to the

                    3.3   Diversion and Remedy.  In addition to the Defaults
provided for in Section 3.1 hereof, if the effect during one or more Interest
Periods of (i) any claim asserted by, on behalf of, or against any one or more
of the Producers or any of its or their property or any interest in any of its
or their property, or against the Source of Debt Service, including, without
limitation, claims asserted by any governmental or taxing authority, or by, or
on behalf of, any creditor, trustee in bankruptcy, custodian, receiver or
similar official or authority, or (ii) the imposition of any Taxes on amounts
payable under any of the Supply Agreements or either of the LNG Sales
Contracts, in any such case constituting Source of Debt Service, or on any
other payment or receipt of the Source of Debt Service (such a claim referred
to in clause (i) or imposition of such Tax referred to in clause (ii), a
"Diversion"), is to cause the Source of Debt Service received by the Borrower
and payable during or at the end of any Interest Period to the Lenders to be
insufficient to satisfy any payment obligation when due under the Loan
Agreement, any of the Notes or the Letter Agreement (the difference between the
amount of the Source of Debt Service received by the Borrower and payable to
the Lenders under the Loan Agreement, the relevant Notes or the Letter
Agreement and the amount which would have been so received and payable but for
such Diversion, the "Diversion Shortfall"), each of the Producers which has
caused or is responsible for such Diversion or to which such Diversion relates,
shall be obligated to pay an aggregate amount to the Agent for the account of
the Lenders, on the dates, in the manner and with the effect of payments made
by the Borrower as provided in the Loan Agreement, the relevant Notes or the
Letter Agreement, on account of its Liability Share of the Diversion Shortfall,
such that the net aggregate amount received from each such Producer by the
Agent for the account of the Lenders pursuant to this Section 3.3, after
deduction of all Taxes required to be deducted or withheld from, or otherwise
paid by the Lenders with respect to, such payment (but excluding Excluded Taxes
required to be so deducted, withheld or paid solely to the extent that the
amount of such Excluded Taxes does not exceed the amount of Excluded Taxes that
would have been deducted, withheld or otherwise paid by the Lenders if there
had been no Diversion Shortfall, and the net amount were paid to, and received
by, the Lenders), shall equal such Producer's Liability Share of the Diversion
Shortfall.

                    3.4   Liability Share Defined.  The "Liability Share" of a
Producer which caused or is responsible for a Default or a Diversion or to
which such Default or Diversion relates which has given rise to a Default
Shortfall or a Diversion Shortfall, as the case may be, shall be with respect
to such Default Shortfall or Diversion Shortfall a percentage determined by
dividing the percentage interest of such Producer (as set forth in Schedule 1
hereto and as adjusted for changes in the Producers' Percentages as defined in
and pursuant to the Supply Agreements or the Production Sharing Percentages as
defined in the recitals thereof) by the aggregate percentage interest of all
Producers (as set forth in such Schedule 1 as so adjusted) which have caused or
which are responsible for such Default or Diversion or to which such Default 
     





                                       25
<PAGE>   29


                          

or Diversion relates. With respect to the imposition of Taxes referred to in
Section 3.3 hereof, each Producer shall be deemed to have caused the
corresponding Diversion to the extent of its percentage interest as shown in
Schedule 1 hereto, adjusted as aforesaid.  No adjustment to the Producers'
Percentages or the Production Sharing Percentages referred to in this Section
3.4 shall be effective for purposes of this Agreement until the Producers have
provided to the Agent a copy of an amended Schedule 1 which properly reflects
such adjustment.  Any adjustment to the Producers' Percentages or the
Production Sharing Percentages or revision to Schedule 1 shall require the
mutual agreement of the Producers, but shall not require any consent, approval
or other action by the Agent, any Co-Agent, any Arranger, any Lender or the
Trustee.

                    3.5   Notices.  Each Producer shall promptly, and in any
event not later than three Business Days after obtaining actual knowledge
thereof, give notice to the Agent of the occurrence of any Default or Diversion
caused by such Producer or for which it is responsible or to which it is
related or any event that, with the giving of notice or the passing of time, or
both, would constitute such a Default or Diversion.


                                     PART 4

                                  INSURED LOSS


                    4.1   Effect of Total Loss of Additional Plant or Other
Facilities Prior to Operational Acceptance.  If any event occurs for which
insurance proceeds are payable by an insurance company under any insurance
policy referred to in Section 1.11(a) hereof relating to an actual total loss
or a constructive, compromised or arranged total loss (within the meaning of
such policy) of the Additional Plant or any of the Other Facilities or any
combination of the foregoing (the "Lost Facilities"), Pertamina agrees as
follows:

                          (a)     Pertamina shall, as promptly as possible in
the circumstances following such event, notify the Agent of the occurrence of
such event and shall, within six months following such event, notify the Agent
in writing whether or not it intends to rebuild or reconstruct the Lost
Facilities.

                          (b)     If Pertamina notifies the Agent that it does
not intend to rebuild or reconstruct the Lost Facilities, it shall promptly pay
to the Agent for the account of the Lenders such amounts as are instructed by
the Agent equal in the aggregate to the lesser of (x) the aggregate amounts
outstanding under the Loan





                                       26
<PAGE>   30


                          

Agreement, Notes and Letter Agreement and (y) the aggregate amount of such
insurance proceeds paid to Pertamina in respect of such event.

                          (c)     If Pertamina notifies the Agent that it
intends to rebuild or reconstruct the Lost Facilities, then it shall proceed to
do so with the services of a reliable and reputable contractor, diligently and
in good faith, and shall provide the Agent with periodic written reports not
less frequently than quarterly in reasonable detail concerning the rebuilding
or reconstruction and including (i) the amount of insurance proceeds received
under such policy, (ii) the amount of funds expended to date on the rebuilding
or reconstruction, (iii) the proposed schedule for completion of the
construction work, and (iv) the progress of the construction work to date.

                          (d)     If, at any time prior to completion,
Pertamina shall terminate the rebuilding or reconstruction of the Lost
Facilities or shall not be proceeding with such rebuilding or reconstruction
diligently and in good faith, then Pertamina shall be obligated promptly to pay
to the Agent for the account of the Lenders, such amounts as are instructed by
the Agent equal in the aggregate to the lesser of (x) the amounts outstanding
under the Loan Agreement, the Note and the Letter Agreement and (y) the
aggregate insurance proceeds which are paid to Pertamina under such policy in
respect of such event and not in good faith expended or committed to be
expended (pursuant to a commitment which cannot by its terms be avoided) on
such rebuilding or reconstruction.

                    4.2   Effect of Total Loss of Insured Bontang Plant.  If
any event occurs for which insurance proceeds are payable by an insurance
company under any insurance policy referred to in Section 1.11(b) hereof
relating to an actual total loss or a constructive, compromised or arranged
total loss (within the meaning of such policy) of the Insured Bontang Plant,
Pertamina agrees as follows:

                          (a)     Pertamina shall, as promptly as possible in
the circumstances following such event, notify the Agent of the occurrence of
such event and shall, within six months following such event, notify the Agent
in writing whether or not it intends to rebuild or reconstruct the Insured
Bontang Plant.

                          (b)     If Pertamina so notifies the Agent that it
does not intend to rebuild or reconstruct the Insured Bontang Plant, it shall
promptly pay to the Agent for the account of the Lenders such amounts as are
instructed by the Agent in an aggregate amount equal to the lesser of (x) the
share referred to below of the total insurance proceeds that are paid to
Pertamina under such policy in respect of such event and (y) the aggregate
amount outstanding under the Loan Agreement, Notes and Letter Agreement after
giving effect to any payment made pursuant to Section 4.1(b) hereof.

<PAGE>   31


                          

                          (c)     If Pertamina notifies the Agent that it
intends to rebuild or reconstruct the Insured Bontang Plant, then it shall
proceed to do so with the services of a reliable and reputable contractor,
diligently and in good faith, applying amounts equal to the proceeds of the
insurance to the extent required, and shall provide the Agent with periodic
written reports not less frequently than quarterly in reasonable detail
concerning the rebuilding or reconstruction and including (i) the amount of
insurance proceeds received under such policy, (ii) the amount of funds
expended to date on the rebuilding or reconstruction, (iii) the proposed
schedule for completion of the construction work, and (iv) the progress of the
construction work to date.

                          (d)     If, at any time prior to completion,
Pertamina shall terminate the rebuilding or reconstruction or shall not be
proceeding with such rebuilding or reconstruction diligently and in good faith,
then Pertamina shall be obligated promptly to pay to the Agent for the account
of the Lenders such amounts as are instructed by the Agent in an aggregate
amount equal to the lesser of (x) the share referred to below or the total
insurance proceeds that are paid to Pertamina under such policy in respect of
such event and not in good faith expended or committed to be expended (pursuant
to a commitment which cannot by its terms be avoided) on such rebuilding or
reconstruction and (y) the aggregate amounts outstanding under the Loan
Agreement, the Notes and the Letter Agreement after giving effect to any
payments made pursuant to Sections 4.1(b) and 4.2(b) hereof.

                    The share referred to in clauses (b) and (d) above of such
total insurance payments shall be (i) the total amount of such payments
multiplied by (ii) a fraction the numerator of which is the aggregate principal
amount of Indebtedness outstanding under the Loan Agreement, Notes and the
Letter Agreement at the time amounts are payable to the Lenders under this
Section 4.2 and the denominator of which is equal to the sum of the aggregate
principal amount of the Indebtedness outstanding under the Loan Agreement and
the aggregate principal amount of all Indebtedness of any Person outstanding at
such time, the holders of which, directly or indirectly, are entitled to share
in the Plant Insurance Proceeds prior to or on an equal and ratable basis with
the Lenders (as the Lenders' rights are determined under this Section 4.2).

                    4.3   Insurance Shortfall.  If by reason of a failure of
Pertamina to comply with Section 1.11 hereof, the share of insurance payments
of the type referred to in Sections 4.1(b) and (d) and 4.2(b) and (d) hereof is
insufficient to pay in full all principal, interest and other amounts payable
under the Loan Agreement and the Notes and all amounts payable under the Letter
Agreement (the amount of such insufficiency, an "Insurance Shortfall"),
Pertamina shall be obligated to pay the amount of the Insurance Shortfall to
the Agent for the account of the Lenders in such amounts as are instructed by
the Agent on the dates, in the manner of and with the effect of payments made
by the Borrower as provided in the Loan Agreement, the Notes and the Letter





                                       28
<PAGE>   32


                          

Agreement, such that the net amount received by the Lenders, pursuant to this
Section 4.3, after deduction of all Taxes required to be deducted or withheld
from, or otherwise paid by the Lenders, with respect to, such payment (but
excluding Excluded Taxes required to be so deducted, withheld or otherwise paid
solely to the extent that the amount of such Excluded Taxes does not exceed the
amount of Excluded Taxes that would have been deducted, withheld or otherwise
paid by the Lenders if there had been no Insurance Shortfall, and the net
amount were paid to, and received by the Lenders out of an amount equal to such
share of insurance), shall equal the Insurance Shortfall.

                    4.4   Other Losses.  Upon a partial loss of the Additional
Plant, any of the Other Facilities or the Insured Bontang Plant (the "Affected
Facilities"), as the case may be, or a total loss thereof with respect to which
Pertamina has not given notice pursuant to Section 4.1 or 4.2 hereof that it
intends not to rebuild and if Pertamina has not applied amounts equal to the
insurance proceeds paid to Pertamina to repayment of the Indebtedness
outstanding under the Loan Agreement, the Notes and the Letter Agreement in the
manner contemplated by Sections 4.1 and 4.2 hereof, Pertamina shall proceed to
rebuild or reconstruct the Affected Facilities with the services of a reliable
and reputable contractor, diligently and in good faith, applying amounts equal
to the proceeds of the insurance referred to in Section 1.11(a) or (b), as the
case may be, to the extent required and shall provide the Agent with the
periodic reports described in clause 4.l(c) or 4.2(c) hereof, as the case may
be, as provided in such clause.

Notes or the payment of any other amounts due under the Loan Agreement or the
Letter Agreement, or shall be had for any claim based on any provision of the

                    6.2   No Waiver; Remedies Cumulative.  No failure to
exercise and no delay in exercising, on the part of any Person having rights

                    6.3   Assignment; Successors and Assigns; Participations.
This Agreement shall be binding upon and inure to the benefit of the Arrangers,

provided that if another corporation, or other entity, wholly owned by or an
agency of the Republic of Indonesia should succeed to all rights and
obligations of Pertamina under the Trust Agreement, the Transportation
Agreement, any Other Transportation Agreement and all of the Basic Agreements
to which it is a party, Pertamina may assign all of its rights and delegate all
of its obligations hereunder to such other corporation, entity or agency, such
assignment and delegation to become effective upon such Person's written
assumption (a copy of which shall be provided to the Agent and which shall
confirm the assignment of rights and the assumption of obligations by such
Person under the Trust Agreement, the LNG Sales Contracts, the Transportation
Agreement, any Other Transportation Agreement and all other Basic Agreements to
which the assignor is a party) of all of Pertamina's obligations hereunder
including, without limitation, the restrictions on assignments and delegations
contained in this Section 6.3 which shall apply to all assignees of the rights
and delegees of the obligations of Pertamina and its assignees and delegees;
and provided further that any Producer other than Pertamina may assign its
rights and delegate its obligations hereunder and assign its rights with
respect to the Source of Debt Service prior to deposit in the Bontang VI
Payment Account, to the extent of and in conjunction with the assignment of its
rights and the delegation of obligations under the Trust Agreement and the
Basic Agreements, in each case to which it is a party, such assignment and
delegation to become effective upon such Person's written assumption (a copy of
which assumption shall be provided to the Agent and which shall confirm to the
extent provided in such assignment and delegation the assignment of rights and
the assumption of obligations under the Trust Agreement and the Basic
Agreements, in each case to which the assignor is a party) of such Producer's
obligations hereunder including, without limitation, the restrictions on
assignments and delegations contained in this Section 6.3 which shall apply to
all assignees of the rights and delegees of the obligations of such Producer
and its assignees and delegees.  The Producers may treat each Lender as the
holder of the Note or Notes drawn to its order and delivered to such Lender
until written notice of transfer shall have been received by them.  All
agreements, representations and warranties made herein shall survive the making
of any such transfer hereunder by any Lender.  Notwithstanding the foregoing,
each Lender may grant participations, in whole or in part, in its rights under
this Agreement to the extent that it may grant participations in its rights
under the Loan Agreement, Notes and Letter Agreement.

                    6.4   Amendments.  Any provision of this Agreement may be
amended or waived if, and only if, such amendment or waiver shall be in writing
and signed (including the form of signatures on any telex with appropriate
confirmed answerback, or telecopied version duly sent by the Person so amending
or waiving) by the Producers and the Majority Lenders; provided that any waiver
need only be signed by the party granting the waiver.  Any such amendment or
waiver shall be signed by the Agent on behalf of the Majority Lenders if the
Agent has been so authorized in writing





                                       32

version signed by the Agent in accordance with the preceding sentence shall be
binding upon the Lenders and any holder of a Note.

                    6.5   Counterparts.  This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts together shall constitute one and the same
instrument.  Complete sets of counterparts shall be lodged with the Agent and
Pertamina.

                    6.6   Section Headings.  The Section headings in this
Agreement are inserted for convenience of reference only and shall be ignored
in construing this Agreement.

                    6.7   Governing Law.  This agreement shall be governed by
and construed in accordance with the laws of the State of New York, United
States of America applicable to agreements made and to be performed entirely
within such state.

                    6.8   Consent to Jurisdiction.

                          (a)     Solely for purposes of this Agreement, each
Producer hereby irrevocably consents that any suit, legal action or proceeding
against it or any of its property with respect to any of the obligations
arising under this Agreement may be brought in any New York State court located
in the Borough of Manhattan, City and State of New York or any Federal Court of
the United States of America located in the Southern District of New York, as
any Lender or the Agent may elect, and by execution and delivery of this
Agreement, each Producer hereby irrevocably submits to and accepts, solely as
aforesaid, with regard to any such suit, legal action or proceeding, for itself
and in respect of its property, generally and unconditionally, the
non-exclusive personal jurisdiction of the aforesaid courts.  Each Producer
hereby irrevocably designates, appoints and empowers CT Corporation System,
1633 Broadway, New York, New York 10019 as its agent to receive for and on its
behalf service of process in New York in any suit, legal action or proceeding
with respect to this Agreement.  It is understood that a copy of any such
process served on such agent shall be promptly forwarded by airmail by the
person commencing such suit, legal action or  proceeding to the relevant
Producer at its address set forth on the signature pages hereof, but the
failure of the relevant Producer to receive such copy shall not affect in any
way the service of such process as aforesaid.  If service of process cannot be
effected in the foregoing manner, each Producer further, solely as aforesaid,
irrevocably consents to the service of process in any such suit, legal action
or proceeding by the mailing of copies thereof by registered or certified
airmail, postage prepaid, return receipt requested, to the respective Producer
at its address set forth on

the signature pages hereof.  The foregoing, however, shall not limit the right
of the Lenders to serve process in any other manner permitted by law or to
bring any suit, legal action or proceeding or to obtain execution of judgment
in any other jurisdiction.

                          (b)     Solely as aforesaid, each Producer hereby
irrevocably waives any objection which it may now or hereafter have to the
laying of venue of any suit, legal action or proceeding arising out of or
relating to this Agreement in any court located in the Borough of Manhattan,
City and State of New York and hereby further irrevocably waives any claim it
may now or hereafter have that a court located in the Borough of Manhattan,
City and State of New York is not a convenient forum for any such suit, legal
action or proceeding.  Pertamina represents and warrants that this Agreement
and its obligations made hereunder and the transactions contemplated hereby
constitute commercial rather than public or governmental acts.  Each Producer
(other than Pertamina, which waives its immunity as provided below) represents
and warrants that it is not entitled to claim immunity from legal proceedings
with respect to itself or any of its property on the grounds of sovereignty or
otherwise under any law or in any jurisdiction where an action may be brought
for the enforcement of any of the obligations arising under this Agreement or
the Trust Agreement.  To the extent that any Producer or any of its property or
the Source of Debt Service, prior to deposit in the Bontang VI Payment Account
has or hereafter may acquire any claim of right to immunity from set-off, legal
proceedings, attachment prior to judgment, other attachment, levy or execution
of judgments on the grounds of sovereignty or otherwise, each Producer on
behalf of itself and any successors, solely as aforesaid, hereby irrevocably
waives such claim of right to immunity for itself and its property in respect
of its obligations arising under this Agreement and the Trust Agreement and
each Producer agrees that it will not assert any such right to immunity in any
way which would impair the performance or ability of the Borrower to perform
its obligations under the Loan Agreement or any of the Notes.

                    6.9   Severability.  If any one or more of the provisions
contained in this Agreement or any document executed in connection herewith
shall be invalid, illegal or unenforceable in any respect under any applicable
law, the validity, legality and enforceability of the remaining provisions
contained herein shall not be in any way affected or impaired.

                    6.10  Reinstatement.  The obligations of the Producers to
make payments under this Agreement shall continue to be effective or shall be
reinstated, as the case may be, if, at any time, a payment or any part thereof,
of any amount paid to a Lender in respect of which a Producer is obligated to
make payment hereunder is rescinded or must otherwise be restored or returned
by the Lender upon the insolvency, bankruptcy or reorganization of the Borrower
or for any other reason, all as though such payment had not been made.

                    6.11  Confidentiality.  No copy of (a) this Agreement, the
Loan Agreement or the Trust Agreement or (b) any other agreement to which any
Producer or the Trustee is a party or any document signed or issued by or on
behalf of any such Producer, which agreement or document is identified by any
Producer to the Agent as confidential, shall, without Pertamina's consent for
the agreements referred to in clause (a), or the consent of the relevant
Producer for agreements or documents referred to in clause (b), be disclosed by
or on behalf of the Agent, any Co-Agent, any Arranger, or any Lender to any
third party, except, prior to the Effective Date, to any prospective lender in
connection with the transactions contemplated hereby pursuant to a
confidentiality undertaking in the form approved by the Producers pursuant to
that certain consent dated December 16, 1996.  Notwithstanding the foregoing
and any provisions of any other confidentiality undertaking between any of the
Producers and any of the Arrangers or the Lenders to the contrary (each such
undertaking being hereby amended to the extent necessary to conform to this
Section 6.11), the agreements and documents referred to in the preceding
sentence and any information, including, without limitation, contracts,
agreements and financial data the disclosure of which is restricted by any such
other undertaking (collectively, "Information") may be disclosed (i) to any
prospective assignee of or participant in the rights of the Lenders under the
Loan Agreement, the Notes and this Agreement upon execution by such Person of a
confidentiality agreement in the form substantially similar to that approved by
the Producers pursuant to that certain consent, dated December 16, 1996 and
(ii) to the extent such Information is required to be disclosed by order or
direction of a court or tribunal of competent authority under applicable law or
by a governmental order, decree, regulation or rule and is required to be made
to any regulatory authority, bank examiner or auditor; provided that the
Arranger or the Lender gives as much prior notice as is practical in the
circumstances to allow the Producer the ability to seek a protective order or
similar remedy and, if the disclosure of the Information is required, furnishes
only such portion of the Information as it is legally compelled to disclose and
exercises reasonable efforts to obtain an order or other reliable assurance
that confidential treatment will be accorded to the disclosed Information.  No
public announcement or statement or publication relating to any of the
foregoing shall be made or released by or on behalf of the Agent, any Co-Agent,
any Arranger or any Lender, without the prior written approval of the
Producers.

                 2.1  Designation of Bontang VI Trustee and Bontang VI General
Account.  Pursuant to the relevant provisions of the Supply Agreements and the
LNG Sales Contracts, Pertamina hereby designates, and each of the Contractors
hereby
<PAGE>   21
                                                                              16

agrees to the designation of, the Bontang VI Trustee named herein, and directs
the Bontang VI Trustee to establish on the next Business Day following the date
hereof and maintain at the Trustee's Office an account, to be designated as the
"Bontang VI General Account."  Pertamina hereby designates the Bontang VI
General Account, and each of the Contractors hereby agrees to such designation
of the Bontang VI General Account, as the account to which the following
amounts shall be paid:

                          (a)     (i) all amounts payable under the KGC Sales
Contract for quantities of LNG purchased on or after January 1, 2000 or for
quantities of LNG required to be purchased on or after January 1, 2000 but
which are not taken by the Buyer thereunder and (ii) all other amounts that
become due and payable under the KGC Sales Contract with respect to the period
commencing on January 1, 2000, in each case as provided therein; and

                          (b)     (i) all amounts payable under the CPC Sales
Contract for quantities of LNG purchased on or after January 1, 2000 or for
quantities of LNG required to be purchased on or after January 1, 2000 but
which are not taken by the Buyer thereunder and (ii) all other amounts that
become due and payable under the CPC Sales Contract with respect to the period
commencing on January 1, 2000, in each case as provided therein.

Without limiting the foregoing, and notwithstanding any other provision herein
to the contrary, the parties hereto acknowledge and agree that all amounts
payable by the relevant Buyer under the relevant LNG Sales Contract with
respect to quantities of LNG purchased on or before December 31, 1999, and any
other amounts that become due and payable thereunder with respect to the period
ending on December 31, 1999, in each case as provided therein, shall not
constitute Bontang VI Trust Funds, and if received by the Bontang VI Trustee
shall be paid over to the Bontang Excess Sales Trustee (all such amounts are
herein called "Excluded Amounts").  For purposes of this Section 2.1,
quantities of LNG shall be deemed to have been purchased when title thereto
passes to the relevant Buyer under the terms of the relevant LNG Sales
Contract, except that any quantities of LNG included in (i) the Fixed Quantity
Period (as defined in the KGC Sales Contract) ending on December 31, 1999
pursuant to Section 7.3(c) of the KGC Sales Contract or (ii) the Fixed Quantity
Period (as defined in the CPC Sales Contract) ending on December 31, 1999
pursuant to Section 7.3(c) of the CPC Sales Contract, that would otherwise be
deemed to have been purchased on or after January 1, 2000 shall instead be
deemed to have been purchased on December 31, 1999.

                 2.2  Bontang VI Trust Funds.  All such amounts that shall have
been received in the Bontang VI General Account pursuant to Section 2.1 (other
than Excluded Amounts), and any other amounts the Bontang VI Trustee may
receive under the terms of this Agreement (together with any securities
acquired by the Bontang VI Trustee pursuant to Article 10 and all interest
thereon) are herein referred to as the
<PAGE>   22
                                                                              17

"Bontang VI Trust Funds."  The respective Sharing Percentages of each Producer
of all Bontang VI Trust Funds shall be credited to the respective Bontang VI
Trust Funds Accounts of such Producer, to be held in trust, however, for the
benefit of those having a right, to the extent provided in this Agreement, to
receive disbursements and distributions hereunder.  Immediately upon the
Bontang VI Trustee's receipt of any funds unambiguously representing amounts
payable to the Bontang VI Trustee with respect to the LNG Sales Contracts
(other than Excluded Amounts), such funds shall be impressed with the trust
created hereby and become a part of the Bontang VI Trust Funds and shall be
deposited in the Bontang VI General Account.

                 2.3  Allocation of Amounts Received.  All amounts received by
the Bontang VI Trustee pursuant to Section 2.1 and designated as representing
amounts payable for LNG delivered, or for LNG required to be purchased, but not
taken, under the LNG Sales Contracts, all amounts paid on account of interest
due by reason of the late payment of invoices, and all demurrage payments by
the Buyers, shall be deemed to be attributable to sales under the LNG Sales
Contracts.  In the event the Bontang VI Trustee receives any amount from any
Buyer which amount is not designated for the Bontang VI General Account or for
any accounts established or to be established under the Other Trust Agreements,
it shall first contact the remitting party in order to determine the proper
designation for the amounts received, and shall solicit and, if possible,
obtain from the remitting party such documentation as the Bontang VI Trustee
deems appropriate as evidence of such designation.  In the event the remitting
party is unable to provide appropriate evidence of such designation, the
Bontang VI Trustee shall notify the Producers of the amounts received, the date
of receipt and any other information relevant to such amount known to the
Bontang VI Trustee.  The Bontang VI Trustee shall thereupon request
instructions as to the proper allocation of the amount received and shall
allocate such amounts between the Bontang VI General Account and any accounts
established under the Other Trust Agreements in accordance with instructions
given jointly by the Producers.  Pertamina shall provide written notice to the
Bontang VI Trustee identifying and itemizing in reasonable detail the portions
of the amounts received in the Bontang VI General Account that do and do not
constitute Source of Debt Service.  Until such notice has been delivered, all
amounts received in the Bontang VI General Account shall be retained therein.

                 2.4  Proceeds of Cargo Insurance.  The Producers hereby agree
that all proceeds from cargo insurance policies covering LNG transported for
sale under the LNG Sales Contracts (other than Excluded Amounts) shall be paid
directly to the Bontang VI Trustee.  All such amounts received by the Bontang
VI Trustee and designated by the insurer as representing proceeds from cargo
insurance policies covering LNG transported for sale under the LNG Sales
Contracts on an ex-ship basis shall become a part of the Bontang VI Trust Funds
and shall be deposited in the Bontang VI General Account.  In the event the
Bontang VI Trustee receives any amounts from insurers that are not designated
as to origin, the procedures specified in Section 2.3 shall apply.

                                                                              18


                 2.5  Payment Under Transportation Agreement.  Pertamina shall
provide instructions that all amounts coming due to Pertamina under the
Transportation Agreement or any other transportation arrangement relating to an
LNG Sales Contract (other than Excluded Amounts) shall be paid directly to the
Bontang VI Trustee.  All such amounts received by the Bontang VI Trustee shall
become a part of the Bontang VI Trust Funds and shall be deposited in the
Bontang VI General Account.  Upon receipt of any such amount that has not been
designated as to origin, the procedures specified in Section 2.3 shall apply.


                                   ARTICLE 3

               POWER TO BORROW AND ENTER INTO INTEREST RATE SWAPS


                 3.1  Enumeration of Powers.

                          (a)     Power to Borrow from the Lenders.  In
addition to its other powers hereunder, the Bontang VI Trustee shall have the
power to borrow money from time to time from the Lenders upon the terms and
conditions set forth below:

                                     (i)   Upon its receipt of notice from the
Producers that they have determined that a credit facility for borrowing by the
Bontang VI Trustee to pay for a portion of the capital costs incurred, or to be
incurred, in connection with the construction or financing of Train H is
desirable, the Bontang VI Trustee, at the direction of the Producers, shall
undertake to obtain such credit facility, which shall be evidenced by the Loan
Agreement, the Notes and the Letter Agreement.

                                     (ii)  The Bontang VI Trustee shall have
the power to enter into or modify the Loan Agreement, the Notes and the Letter
Agreement upon its receipt of notice from Pertamina and each of the Contractors
that they have approved the form and terms of such agreements or modifications
and that they authorize and request the Bontang VI Trustee to enter into such
agreements or modifications.  The Bontang VI Trustee shall have the power, as
specified herein, to obtain and repay Indebtedness and to pay other amounts and
to perform other obligations under the Loan Agreement, the Notes and the Letter
Agreement.  Notwithstanding the provisions of Section 13.3, no representatives
of the Contractor Groups, any Contractor or any other individual or entity
shall have authority to give any approval under this Section 3.1(a) for any
Contractor other than itself, unless such Contractor shall give notice to the
Bontang VI Trustee that it has appointed such representative or other
individual or entity to give such approval.

                                    (iii)  The Loan Agreement, the Notes and
the Letter Agreement shall contain provisions acceptable to the Bontang VI
Trustee to the effect
<PAGE>   24
                                                                              19

that no recourse may be had nor any claim thereunder made against Bank of
America National Trust and Savings Association, in its individual capacity,
other than for breach of a representation or warranty made in its individual
capacity or for gross negligence or willful misconduct.

                          (b)     Power to Incur Subordinated Indebtedness.  In
addition to its other powers hereunder, the Bontang VI Trustee shall have the
power at any time to incur Indebtedness that is payable out of amounts of the
Source of Debt Service only after (i) the Bontang VI Trustee shall have
accumulated amounts in the Debt Service Account and the Reserve Account during
each Interest Period required to be accumulated therein pursuant to Section 3.2
or 3.3(d), as applicable, and (ii) any amounts required to be deposited in the
Debt Coverage Reserve Account and paid to the Lenders therefrom under Sections
3.2 and 3.3, as applicable, have been so deposited and paid (such Indebtedness,
"Subordinated Indebtedness"), as follows.  Upon its receipt of notice from the
Producers that they have determined that Subordinated Indebtedness in the form
of a credit facility for borrowing by the Bontang VI Trustee to pay for a
portion of the capital costs incurred, or to be incurred, in connection with a
Financed Capital Project is desirable, the Bontang VI Trustee, at the direction
of the Producers, shall undertake to obtain and enter into one or more
appropriate agreements relating to such Subordinated Indebtedness; provided,
however, that the Bontang VI Trustee shall not enter into any such agreement or
amendment prior to (i) receiving written notice from the Agent that the
Majority Lenders have approved such agreement in form and substance in
accordance with Section 6.4 of the Loan Agreement, and (ii) entering into an
appropriate amendment to this Agreement to make provision for making payments
under the agreements relating to such Subordinated Indebtedness to the extent
provided in the first sentence of this Section 3.1(b), which amendment shall
have been approved in writing as to form and substance by the Majority Lenders.

                          (c)     Power to Incur Pari Passu Swap Indebtedness.
In addition to its other powers hereunder, the Bontang VI Trustee shall have
the power to incur Indebtedness (other than Subordinated Indebtedness) in
respect of interest rate swap arrangements of the Bontang VI Trustee entered
into solely for the purpose of exchanging floating interest rate obligations of
the Bontang VI Trustee under the Loan Agreement into fixed interest rate
obligations if such Indebtedness is only payable out of Source of Debt Service
and is pari passu in right of payment and does not benefit from any Encumbrance
other than equally and ratably with, or subordinate to, the Indebtedness owed
to the Lenders under the Loan Agreement, the Notes and the Letter Agreement
("Pari Passu Swap Indebtedness").  Upon its receipt of notice from the
Producers that they have determined that such Pari Passu Swap Indebtedness is
desirable, the Bontang VI Trustee, at the direction of the Producers, shall
undertake to obtain and enter into one or more appropriate agreements relating
to such Pari Passu Swap Indebtedness; provided, however, that the Bontang VI
Trustee shall not enter into any such agreement prior to (i) receiving written
notice from the Agent that the
<PAGE>   25
                                                                              20

Majority Lenders have approved such agreement in form and substance in
accordance with Section 6.4 of the Loan Agreement, and (ii) entering into an
amendment to this Agreement making provision for making payments under such
agreement on a pari passu basis out of the Source of Debt Service with the
payments to be made to the Lenders under the Loan Agreement, which amendment
shall have been approved in writing as to form and substance by the Majority
Lenders.

                          (d)     Application of Certain Provisions.  The
provisions contained in the last sentence of Section 3.1(a)(ii) and in Section
3.1(a)(iii) relating to the Loan Agreement shall apply equally to any
agreements relating to Subordinated Indebtedness or Pari Passu Swap
Indebtedness to be entered into by the Bontang VI Trustee pursuant to Section
3.1(b) or 3.1(c).

                 3.2  Accumulation of Debt Service.

                          (a)     Capital Payment Dates.  The Loan Agreement
shall provide that all payment dates for payment of principal and interest
thereunder shall be uniform dates within each calendar quarter (each such date
for payment of principal or interest, a "Capital Payment Date").

                          (b)     Notices.  (i)  The Loan Agreement shall
provide for the Bontang VI Trustee to receive, at the time of the initial
borrowing and each subsequent borrowing thereunder in each case in respect of
the Quarterly Period in which such borrowing occurs and on or about the first
day of each Quarterly Period thereafter, a notice (a "Scheduled Payment
Notice") from the Agent of the amounts of Scheduled Principal, Deferred
Principal, regularly scheduled Interest and regularly scheduled Lenders Fees
and Expenses payable on the Capital Payment Date occurring at the end of such
Quarterly Period (specifying the portions thereof payable to the Finance
Company, on the one hand, and the other Lenders, on the other).

                                     (ii)  The Loan Agreement shall provide for
the Bontang VI Trustee to receive notice (a "Non-Scheduled Payment Notice")
from the Agent of other amounts payable under the Loan Agreement, the Notes and
the Letter Agreement as the same shall become due and payable, designating
whether such amounts constitute principal, Lenders Fees and Expenses, Interest,
Special Payments or Mandatory Prepayments (specifying the portions thereof
payable to the Finance Company, on the one hand, and the other Lenders, on the
other).

                                    (iii)  The Loan Agreement shall provide for
the Bontang VI Trustee to receive on or about December 31, 1999 and on or about
the first day of each Quarterly Period thereafter and on or following the date
of delivery of each Notice of Borrowing delivered thereafter, a notice (an
"Anticipated Loan Amount Notice") from the Agent of the sum (such sum, the
"Anticipated Loan Amounts") of Scheduled Principal and Deferred Principal to be
payable to the Lenders (other than
<PAGE>   26
                                                                              21

Affected Lenders) on each of the two Capital Payment Dates next succeeding the
Capital Payment Date occurring at the end of such Quarterly Period plus all
Interest to accrue during the two Quarterly Periods next succeeding such
Quarterly Period plus all Lenders Fees and Expenses reasonably anticipated to
be payable during such next two Quarterly Periods; provided, however, that
during the period beginning January 1, 2000 and ending on the day immediately
preceding the first day of the Amortization Period, such sum shall be equal to
(and the phrase Anticipated Loan Amounts shall refer to) the Scheduled
Principal and Deferred Principal reasonably anticipated to become due to the
Lenders (other than Affected Lenders) with respect to the first two Maturity
Dates plus all Interest and Lenders Fees and Expenses reasonably anticipated to
be due on such Maturity Dates.

                                     (iv)  The Bontang VI Trustee, without any
action or approval being required of the Producers, shall be entitled to rely
conclusively on each such notice in the absence of manifest error.

                          (c)     Establishment of Debt Service Account and
Reserve Account.  On or before the Effective Date, the Bontang VI Trustee shall
open in its own name, as Bontang VI Trustee, at the Trustee's Office, two
subaccounts of the Bontang VI General Account, one designated as the "Debt
Service Account" (which term shall include all subaccounts thereof), and the
other designated as the "Reserve Account" (which term shall include all
subaccounts thereof).  On or before the Effective Date, the Bontang VI Trustee
shall also open in its own name at the Trustee's Office (i) three separate
subaccounts of the Debt Service Account (such subaccounts to be designated as
the "Loan Account," the "Special Payment Account" and the "Mandatory Prepayment
Account") and (ii) two separate subaccounts of the Reserve Account (such
subaccounts to be designated as the "Regular Reserve Account" and the "Debt
Coverage Reserve Account," respectively), all such subaccounts to be used for
the receipt, administration and payment of principal, interest and other
amounts due or to become due under the Loan Agreement.

                          (d)     Depositing of Borrowings for Lenders Fees and
Expenses.  If the Bontang VI Trustee borrows amounts under the Loan Agreement
for the purpose of paying any Lenders Fees and Expenses due thereunder as
specified in all Scheduled Payment Notices and Non-Scheduled Payment Notices
received by the Bontang VI Trustee, without duplication, such amounts shall be
immediately deposited into the Loan Account.

                          (e)     Depositing of Borrowings for Interest.  If
the Bontang VI Trustee borrows amounts under the Loan Agreement for the purpose
of paying any Interest due thereunder as specified in all Scheduled Payment

without duplication, such amounts shall be immediately deposited into the Loan

                          (g)     Depositing of Borrowing for Regular Reserve

for the purpose of funding the Regular Reserve Account, such amount shall be
immediately deposited into the Regular Reserve Account.

                          (h)     Depositing of Borrowings for Selected
Qualified Bank.  If the Bontang VI Trustee borrows amounts under the Loan
Agreement for the purpose of reimbursing the Producers for amounts paid by them
to a Selected Qualified Bank retained pursuant to Section 6.6 of the Loan
Agreement to specify the assumptions necessary for calculating the Debt
Coverage Ratio, such amounts shall be immediately deposited into the Bontang VI
Payment Account.

                          (i)     Depositing of Source of Debt Service Before
Amortization Period.  Subject to all payments (if any) required by Section
3.3(d) having first been made, during the period beginning on January 1, 2000
and ending on the day immediately preceding the first day of the Amortization
Period, the Bontang VI Trustee shall, upon receipt, promptly pay over to the

paid into the Debt Service Account and the Reserve Account under Sections 3.2
and 3.3, and of all amounts required to be paid under Articles 5, 6 and 7 and
Sections 8.5 and 11.2, shall be charged to each such Producer's Bontang VI
Trust Fund Account.  The (i) respective Sharing Percentages of each Producer of
any funds deposited in the Bontang VI Payment Account pursuant to Section 4.2,
(ii) amount of any excess funds distributed to each Producer from the Debt
Service Account and Reserve Account pursuant to Section 3.5, and (iii) portion
due each Producer from any amounts received by the Bontang VI Trustee from the
Disbursement Trustee pursuant to Section 3.7(c), shall be credited to each such
Producer's Bontang VI Trust Fund Account.  Whenever and to the extent that the
amount held in the Bontang VI Payment Account at the end of any business day of
the Bontang VI Trustee in the City of New York is in excess of the Approved
Level of Working Capital, after having deducted all amounts of Source of Debt
Service then required to be paid into the Debt Service Account and the Reserve
Account under Sections 3.2 and 3.3, and all amounts then payable by the Bontang
VI Trustee under Articles 5 and 6 and Sections 8.5 and 11.2, then, except as
otherwise provided in Section 8.3 or Article 12, such excess shall be
immediately paid out to the Producers in accordance with their respective
Sharing Percentages applicable to such amount, as specified in the most recent
certificate for the current year furnished pursuant to Section 8.3.

                                                                              41

                 8.3  Accountants.  The Producers shall mutually appoint a firm
of independent public accountants to act as the accountants hereunder (the
"Accountants") and shall promptly advise the Bontang VI Trustee of such
appointment.

                 The Accountants shall be directed to furnish to the Bontang VI
Trustee (with a copy to the Producers) a certificate on or before the 15th day
of December in each calendar year (initially for 1997 on or before December 15,
1997) setting forth the respective Sharing Percentages of each Producer for the
following calendar year (and for 1997 in the case of the first such
certificate) with respect to each LNG Sales Contract in effect during such
calendar year.

                 The Sharing Percentages with respect to an LNG Sales Contract
shall be calculated as provided in the respective Supply Agreements applicable
to such LNG Sales Contract and the respective Production Sharing Contracts,
based upon actual or estimated production and costs as required thereby.

                 The Accountants shall also be directed to furnish to the
Bontang VI Trustee (with a copy to the Producers) on or before the 15th day of
March, June and September in each calendar year, commencing March 15, 1998 a
revision of the certificate furnished for such year setting forth the
respective Sharing Percentages of each Producer based upon revised estimates of
production and costs for such year.

                 In addition, the Accountants shall be directed to furnish to
the Bontang VI Trustee (with a copy to the Producers) on or before the 15th day
of February in each calendar year, commencing February 15, 1998, a final
version of the certificate for the previous year setting forth the respective
Sharing Percentages of each Producer based upon actual production and costs for
the previous year.

                 Every revised and final certificate shall specify the amount,
if any, by which the aggregate amount paid by the Bontang VI Trustee to each
Producer pursuant to the initial certificate and any earlier revisions thereof
under this Article 8 was greater or less than the amount that would have been
paid to each on the basis of the Sharing Percentages which are certified
therein and shall specify the amount that will be required to be paid to any
underpaid Producer, in order to bring the total amount paid to it into
equitable relation to the amount paid to any overpaid Producers so that the
payments, as adjusted, would be in accordance with such Sharing Percentages.
In the event that any such certificate indicates that any of the Producers has
been underpaid, the Bontang VI Trustee, after receipt of the certificate, shall
pay to any such Producers pro rata in proportion to the amount by which each
such Producer was underpaid, all amounts otherwise payable under this Article 8
to the Producers which have been overpaid until each such underpaid Producer
shall have received the entire amount stated in the certificate as required to
be paid to such underpaid Producer.  After each such Producer has received the
entire amount it is entitled to receive as aforesaid, the Bontang VI Trustee
shall make all future payments to the Producers out
<PAGE>   47
                                                                              42

of the funds remitted in respect of the LNG Sales Contracts in accordance with
the Sharing Percentages specified in the most recent certificate relating
thereto furnished to the Bontang VI Trustee pursuant to this Section 8.3.

                 8.4  Arrangements for Payment.  Each Producer shall make such
reasonable arrangements with the Bontang VI Trustee as it shall deem
appropriate for the payment to it of amounts payable to it under the terms of
this Article 8.  Except as otherwise provided in Section 8.5, each Contractor
shall make its own arrangements with respect to such payments directly with the
Bontang VI Trustee and, notwithstanding the provisions of Section 13.3, the
representative of any Contractor Group shall have no authority to act for any
Contractor other than itself in making such arrangements.

                 8.5  Special Disbursement Instructions.  The Producers
acknowledge that from time to time it may be necessary for amounts which would
otherwise be paid to Producers pursuant to Section 8.2 to be paid instead to
(a) persons who have submitted invoices or other statements for charges with
respect to the production, sale or delivery of LNG or LPG from the Bontang
Plant under sales contracts other than the LNG Sales Contracts, (b) the trustee
under any trust established to pay charges of the type described in (a) above,
(c) Chinese Petroleum Corporation to satisfy obligations of Pertamina under the
Mutual Incentive Sharing Side Letter or (d) the trustee under any of the Other
Trust Agreements, in order to satisfy certain obligations of the Producers
having interests in the Bontang VI Payment Account.  Accordingly,
notwithstanding the payment arrangements made with the Bontang VI Trustee
pursuant to Section 8.4, each Contractor hereby authorizes the representative
of any of the Contractor Groups of which it is a member, as designated in or
pursuant to Section 13.3, to give to the Bontang VI Trustee from time to time
on its behalf such Special Disbursement Instructions as such representative may
deem necessary or appropriate to authorize such payments.  Each representative
shall give copies of any such Special Disbursement Instruction to the members
of its Contractor Group contemporaneously with the transmission thereof to the
Bontang VI Trustee, by the same means of transmission.  As used herein, a
"Special Disbursement Instruction" means an instruction so entitled which (i)
is given by the Producers as provided in Section 13.3, (ii) instructs the
Bontang VI Trustee to pay to persons described in clauses (a), (b), (c) or (d)
above any amount which would otherwise be paid to Producers pursuant to Section
8.2, and (iii) specifies the funds from which such payment is to be made.  Any
Special Disbursement Instruction requiring payment to another trustee shall
also specify the account or accounts to which such funds are to be credited and
direct the Bontang VI Trustee to notify such trustee that such payment is a
Special Disbursement Amount for the account or accounts so specified.  The
inclusion of this Section 8.5 shall have no effect on the authority of the
Bontang VI Trustee to act and rely upon any other special disbursement or
transfer instruction which does not comply with this Section 8.5 so long as
such instruction is given in an instrument executed by all of the Producers.

                 8.6  Payment Procedures.  The Producers shall agree with the
persons specified in Section 8.5(a) on appropriate procedures for the payment
of the relevant invoices or statements and shall advise the Bontang VI Trustee
of such procedures, which shall include a requirement that the person receiving
payment furnish the Bontang VI Trustee with an acknowledgment that each payment
by the Bontang VI Trustee hereunder fully satisfies the liabilities of the
person to which such invoice or statement is addressed with respect thereto.

                 8.7  Receipt of Special Disbursements.  The Bontang VI Trustee
may from time to time receive Special Disbursement Amounts from the trustee
under any of the Other Trust Agreements.  Immediately upon the Bontang VI
Trustee's receipt of any funds identified as a Special Disbursement Amount,
such funds shall be impressed with the trust created hereby and become a part
of the Bontang VI Trust Funds.  Any such amounts received by the Bontang VI
Trustee shall be deposited in the account hereunder specified by the remitting
trustee.


                                   ARTICLE 9

              PROCEDURES RESPECTING ACCOUNTS UNDER THIS AGREEMENT

                 9.1  Accounting for Assets.  All assets under the jurisdiction
and control of the Bontang VI Trustee and held from time to time in the Bontang
VI Trust Funds shall be accounted for within the Bontang VI General Account
specifying the subaccount and LNG Sales Contract to which such assets may be
allocated, the bank or banks at which cash deposits may be maintained and the
place or places at which investment securities may be held in custody for the
account of the Bontang VI Trustee.  The Bontang VI Trustee shall maintain such
books of account and other records as may be necessary to ensure full and
proper segregation of the funds credited to such accounts as may be established
by the Bontang VI Trustee hereunder.  It shall also segregate, and keep such
accounts separate, from any accounts which may be established by it as trustee
and paying agent under the Other Trust Agreements.  Such books of account shall
be open to inspection by the duly authorized representatives of the Producers
at all reasonable times.

                 9.2  Reports.  The Bontang VI Trustee shall furnish to each of
the Producers the following reports:

                          (a)     As soon as practicable (but not later than 45
days) after the close of each calendar year, a statement prepared by the
Bontang VI Trustee, setting forth the amount and source (by category and the
relevant LNG Sales Contract) of funds received pursuant to this Agreement and
the disbursement of such funds as disclosed by the records and accounts kept by
the Bontang VI Trustee pursuant to Sec-
<PAGE>   49
                                                                              44

tion 9.1 during such preceding calendar year, and a statement of the cash and
investments held in the accounts under this Agreement as of the end of such
period.

                          (b)     Within 20 days after the close of each
calendar quarter a statement prepared by the Bontang VI Trustee setting forth
the amount and source (by category and the relevant LNG Sales Contract) of
funds received pursuant to this Agreement and the disbursements of such funds
as disclosed by the records and accounts kept by the Bontang VI Trustee
pursuant to Section 9.1 during such preceding calendar quarter and a statement
of the cash and investments held in the accounts under this Agreement as of the
end of such period.

                          (c)     Promptly after its receipt or disbursement of
any funds pursuant to this Agreement, the Bontang VI Trustee shall notify the
Producers by telex or telecopier of such transactions specifying the amount and
the source (by category and the relevant LNG Sales Contract) of the funds
received and disbursed and the amounts credited or charged to the Bontang VI
General Account or any subaccount thereof.

                 Notwithstanding the provisions of Section 13.3 respecting the
representatives of the Contractors' Groups, each of the reports required by
clauses (a) and (b) of this Section 9.2 shall be furnished by the Bontang VI
Trustee directly to each Contractor at its address specified pursuant to
Section 13.3.

                 9.3  Producer Accounts.  The Bontang VI Trustee shall maintain
separate accounts for each Producer which are sufficient to reflect each such
Producer's interest in the assets, liabilities, receipts and disbursements of
the Bontang VI Trust Funds and its right to distributions therefrom (the
"Bontang VI Trust Funds Accounts").  It is the intention of each Producer that
the trust created hereby be a security trust of the type described in Treas.
Reg. 1.61- 13(b) and I.T. 1942, III-1 C.B. 11 (1924).  Accordingly, each
Producer agrees for U.S. income tax purposes to account for its share of the
receipts and disbursements made pursuant to this Agreement as if it had
received such amounts directly and made such disbursements directly, and the
Bontang VI Trustee agrees for United States income tax purposes, unless advised
by the U.S. Internal Revenue Service to the contrary, to treat such receipts
and disbursements in a manner consistent with its status as the agent for each
such party or, if so advised by Bontang VI Trustee's counsel, as the trustee of
a separate grantor trust for each such party within the meaning of Section 671
of the U.S. Internal Revenue Code of 1986, as amended, and the regulations
thereunder.

           INVESTMENT OF FUNDS HELD IN ACCOUNTS UNDER THIS AGREEMENT

                 10.1  Permitted Investments.  The Bontang VI Trustee shall
invest amounts held by it from time to time in the Bontang VI Payment Account,
the Debt Service Account and the Reserve Account solely in:

                                     (i)   Eurodollar bank time deposits or
Eurodollar certificates of deposit with banks whose deposits are rated "P-1" by
Moody's Bank Credit Report Service and "A-1+" by Standard and Poor's Rating
Group CD Ranking Service, which may include any affiliate of the Bontang VI
Trustee satisfying the foregoing criteria; or

                                     (ii)  such other types of short-term
interest-bearing bank time deposits and certificates of deposit (x) as to which
there is applicable a sovereign guarantee of repayment of principal, or other
evidence of sovereign support in respect of such repayment as approved by the
Producers and, with respect to amounts, if any, held in the Debt Service
Account or the Reserve Account or any subaccount thereof for the Lenders under
the Loan Agreement, approved by the Majority Lenders; and (y) issued by banks
having at least $100,000,000.00 (or its equivalent) of capital and earned
surplus (or equivalent accounts) as reflected in the then current financial
statements of the issuing banks, which may include any affiliate of the Bontang
VI Trustee satisfying the foregoing criteria; or

                                    (iii)  if, due to the relatively small
amount of funds to be invested, the unconventional period during which such
funds are to be invested or similar factors, investments of the type authorized
by clauses (i) and (ii) above are not generally available for such funds, the
Bontang VI Trustee may invest such funds in short-term Eurodollar time
deposits, Eurodollar certificates of deposit or Eurodollar repurchase
agreements, or any combination of the foregoing, in each case with any bank or
banks each having at least $100,000,000.00 (or its equivalent in any other
currency) of capital and earned surplus (or equivalent accounts) as reflected
in the then current financial statements of such bank or banks, which may
include any affiliate of the Bontang VI Trustee satisfying the foregoing
criteria; provided, however, that the aggregate principal amount of such funds
so invested shall not exceed $1,000,000.00 at any one time.

                 In no event shall the aggregate amount invested by the Bontang
VI Trustee pursuant to the foregoing provisions in time deposits or
certificates of deposit with, or issued by, respectively, any one bank exceed
10% of such bank's capital and earned surplus (or equivalent accounts) as
reflected in the bank's then current financial statements.  For purposes of
investments pursuant to clause (ii) above, the Bontang VI Trustee shall request
the approval of the Producers in accordance with Section 13.3
<PAGE>   51
                                                                              46

and, as applicable, the Majority Lenders by giving notice, which request shall
specify the type of investment proposed and the nature of any sovereign
guarantee or support applicable thereto.  The Bontang VI Trustee shall use its
best efforts to assure that the final maturity of any such investment does not
extend beyond the time when the amounts used to acquire such investments would
be required for any other application hereunder.

                 For the purposes of investments made pursuant to the foregoing
clauses (i) and (iii), the Bontang VI Trustee may submit to the Producers and
to the Agent a list of bank issuers of securities satisfying the criteria of
such clauses and may request that the Producers and the Agent designate one or
more such issuers, on the list or otherwise, as acceptable to them for
investment purposes.  Upon receipt of such list and request, the Producers and
the Agent shall designate from such list or propose one or more issuers
satisfactory to them for such investment purposes; if more than one such issuer
is designated, the designation shall indicate a priority among them; and no
such designation with respect to investments of amounts in the Bontang VI
Payment Account shall require any approval or other action on the part of the
Lenders or the Agent.  The Bontang VI Trustee shall make no investments under
such clauses (i) and (iii) until it has received such a designation.  The
Bontang VI Trustee shall not be liable for the results of any investments made
in the securities contemplated by clauses (i) and (iii) of issuers so approved.

                 10.2  Prudence and Yield.  In making any investments pursuant
to Section 10.1 the Bontang VI Trustee shall be guided by the standards of a
prudent investor seeking the maximum yield available consistent with security
of principal at all times; provided that the Bontang VI Trustee shall have no
liability whatsoever for the results of any investment approved by the
Producers and the Agent.

                 10.3  Interest Allocation.  Interest or any other income
arising out of investment of the Bontang VI Trust Funds shall be and become a
part of the Bontang VI Trust Funds, allocated to the account for which such
investment was made.  Interest or any other income arising out of investment of
funds in a subaccount of the Debt Service Account or the Reserve Account shall
be allocated to the subaccount for which such investment was made.

                       CONCERNING THE BONTANG VI TRUSTEE


                 11.1  Duties.  In connection with its duties, rights and
powers under this Agreement (including in relation to transactions it may enter
into pursuant hereto), the Bontang VI Trustee shall be subject to the
following:
<PAGE>   52
                                                                              47


                          (a)     The Bontang VI Trustee shall be entitled to
act upon any notice, certificate, request, direction, waiver, receipt or other
document which it in good faith believes to be genuine; and it shall be
entitled to rely upon the due execution, validity and effectiveness, and the
truth and acceptability of any provisions contained therein.

                          (b)     The Bontang VI Trustee shall not be liable
for any error of judgment or for any act done or omitted by it in good faith or
for any mistake of fact or law, or for anything which it may do or refrain from
doing, including, but not limited to, with respect to any provision herein
requiring the Bontang VI Trustee to use its best efforts, except for its own
gross negligence or willful misconduct, nor shall the Bontang VI Trustee be
liable for special, indirect or consequential loss or damage of any kind
including, without limitation, lost profits, except such losses or damages
resulting from its willful misconduct.

                          (c)     The Bontang VI Trustee may consult with, and
obtain advice from, accounting and legal advisers and it shall incur no
liability or loss and shall be fully protected in acting in good faith in
accordance with the opinion and advice of such advisers.

                          (d)     The Bontang VI Trustee shall have no duties
other than those specifically set forth or provided for in this Agreement.  The
Bontang VI Trustee shall have no obligation to familiarize itself with and
shall have no responsibility with respect to any agreement to which it is not a
party relating to the transactions contemplated by this Agreement nor any
obligation to inquire whether any notice, instruction, statement or calculation
is in conformity with the terms of any such agreement, except for those
irregularities, errors or mistakes apparent on the face of such document or to
the knowledge of the Bontang VI Trustee.  If, however, any remittance or
communication received by the Bontang VI Trustee appears erroneous or irregular
on its face, the Bontang VI Trustee shall be under a duty to make prompt
inquiry to the person or party originating such remittance or communication in
order to determine whether a clerical error or inadvertent mistake has
occurred.

                 11.2  Compensation.  The Bontang VI Trustee shall be entitled
to reasonable compensation to be agreed upon from time to time among the
parties for the services to be performed by the Bontang VI Trustee hereunder or
under any other document entered into by the Bontang VI Trustee at the request
of, or with the approval of, the Producers, or contemplated hereby or thereby,
and to be reimbursed for all reasonable out-of-pocket expenses incurred by the
Bontang VI Trustee in connection therewith.  The Bontang VI Trustee may charge
such agreed compensation and expenses to the Bontang VI Payment Account,
providing the Producers with such evidence as to the nature and amount of such
expenses as any of the Producers may reasonably require.  If the balance in the
Bontang VI Payment Account is insufficient therefor, each Producer shall pay
such compensation and expenses to the Bontang VI
<PAGE>   53
                                                                              48

Trustee, provided, however, that the obligation of each respective Contractor
with respect to this Section 11.2 shall be pro rata in accordance with its
respective Sharing Percentage.

                 11.3  Resignation.  The Bontang VI Trustee may, at any time,
by notice to the Producers and the Agent, tender the Bontang VI Trustee's
resignation as Trustee and Paying Agent under this Agreement.  The Producers
may, at any time by notice jointly given by them, terminate the Bontang VI
Trustee's appointment hereunder.  Such resignation or termination shall be
effective as from the appointment of a successor as hereinafter provided.

                 11.4  Appointment of Successor.  Within 60 days of receipt of
a notice of resignation or issuance of a notice of termination, the Producers
shall jointly appoint a successor, being a bank in the United States acceptable
to the Producers.  The proposed successor bank (the "Successor") shall promptly
give notice of its appointment to the Bontang VI Trustee and shall execute and
deliver to each of the parties hereto an instrument in writing accepting the
successor's appointment hereunder which shall specify the office of the
Successor in the United States which is to be the Trustee's Office for the
purpose of this Agreement.

                 11.5  Application to Court.  If in any case a Successor shall
not be appointed pursuant to the foregoing provisions of this Article 11 within
the 60 days aforesaid, the Bontang VI Trustee may apply to any court of
competent jurisdiction to appoint a Successor, notwithstanding the provisions
of Section 13.2.  Such court may thereupon, in any case, after such notice, if
any, as such court may deem proper and prescribe, appoint a Successor.

                 11.6  Successor Vested with Rights.  Upon and from the
execution and delivery of its acceptance in writing as aforesaid, the Successor
without any further act or deed shall become fully vested with all the rights,
powers and duties and subject to all the obligations of the Bontang VI Trustee
hereunder, but the Bontang VI Trustee, upon payment of all sums due it and on
the written request of the Producers shall execute and deliver an instrument
transferring to the Successor the Bontang VI Trust Funds, including all funds
held in the Bontang VI Payment Account, the Debt Service Account and the
Reserve Account and assigning to the Successor all its rights hereunder and
under any Disbursement Trust Agreement and all of the Bontang VI Trustee's
rights with respect to any Bontang VI Depositary.

                 11.7  Payments After Notice.  Upon and from the date of
notification from any Successor, any person required to pay amounts to the
Bontang VI Trustee under this Agreement shall pay the Successor at its office
specified as aforesaid all amounts described herein as payable to the Bontang
VI Trustee.

                                                                              49

                 11.8  Indemnification.  The Producers hereby agree to
indemnify the Bontang VI Trustee for, and to hold it harmless against, any
loss, liability, claim, judgment, settlement, compromise or reasonable expense
incurred or suffered without gross negligence or willful misconduct on the part
of the Bontang VI Trustee, arising out of or in connection with its entering
into this Agreement, the Loan Agreement or any other document entered into by
the Bontang VI Trustee at the request of, or with the approval of, the
Producers, or contemplated hereby or thereby, and carrying out its duties or
exercising its rights hereunder or thereunder, including, but not limited to,
the cost and expenses of defending itself against any claim of liability in the
premises.

                 11.9  Trustee in Individual Capacity.  Each of the parties
hereto acknowledges and consents that the Bontang VI Trustee, in its individual
capacity, or any affiliate thereof, shall have the same rights, powers and
authority to enter into any deposit agreement, loan agreement or any other
banking or business relationship permitted by law with any of the Producers,
the Lenders or the Agent (without having to account therefor to any of the
Producers) as though the Bontang VI Trustee were not the Trustee and Paying
Agent under this Agreement.

                            DEBT SERVICE ALLOCATION

                 12.1  Debt Service Allocation Definitions.  In addition to and
in amendment of the terms defined elsewhere in this Agreement, the following
terms shall, solely for purposes of this Article 12, have the meanings set
forth below:

                 "Aggregate Dollar Share" shall have the meaning set forth in
Section 12.3.

                 "Allocation Trust Agreements" shall mean this Agreement, the

Trustees from time to time certificates setting forth, the Estimated Debt
Service Percentages for each Producer of the estimated amounts of each type of
Debt Service to be paid by the Borrowing Trustees, and the Contingent Support
Trustees (the percentages last so certified as to each period for each Producer
being its "Estimated Debt Service Percentages").  Each Trust Agreement to which
a Borrowing Trustee is a party provides that such Borrowing Trustee shall
promptly give notice to the Allocation Trustees of (i) each payment into a Debt
Service Account made by such Borrowing Trustee, specifying any amounts so paid
from the proceeds of any borrowing under a Financing Agreement and, in the case
of the Bontang III Trustee, from Contingent Support, (ii) each transfer,
payment or distribution from a Debt Service Account, or any disbursement trust
pursuant to a Financing Agreement, of funds in excess of the amount required to
be held therein from time to time, (iii) each payment of Debt Service of which
such Borrowing Trustee has been notified made by a Producer pursuant to a
Producers Agreement, and (iv) the portion of each such payment of Debt Service,
whether made by such Borrowing Trustee or a Producer, borne by each Producer,
after taking into account such Producer's interest in any excess funds
transferred, paid or distributed from any Debt Service Account, or any
disbursement trust pursuant to a Financing Agreement, to or for the account of
any Producers.  Each Trust Agreement to which a Contingent Support Trustee is a
party provides for similar notices.

                 In the event that such notices received by the Bontang VI
Trustee, together with the notices referred to in the last sentence of this
paragraph and all similar notices received from the other Allocation Trustees,
considered in the aggregate, show at any time that any Producers have borne
more than their Estimated Debt Service Percentages of Debt Service ("underpaid
Producers"), the Bontang VI Trustee shall thereafter make Provisional Debt
Service payments to the underpaid Producers, pro rata in proportion to the
excess amount borne by each such Producer, out of all amounts otherwise payable
under Article 8 to the Producers which have borne less than their Estimated
Debt Service Percentages of such Debt Service until the Reimbursement Amount of
the aggregate Provisional Debt Service payments received by each of the
underpaid Producers from the Allocation Trustees equals the excess amount of
Debt Service borne by such Producer.  The Bontang VI Trustee shall promptly
advise each other Allocation Trustee of each such Provisional Debt Service
payment made by the Bontang VI Trustee.

                 12.3  Aggregate Dollar Share.  The Debt Service Allocation
Agreement also requires that the Accountants calculate, and deliver to the
Allocation Trustees from time to time certificates setting forth, the portion
of Debt Service each Producer should have borne of the Debt Service paid by the
Borrowing Trustees and the Contingent Support Trustees (the amount last so
certified as to each period for each Producer being its "Aggregate Dollar
Share") and the portion thereof which has actually been borne by each Producer.
In the event that any such calculations indicate that any Producers have borne
more than their Aggregate Dollar Shares of Debt Service during the period in
<PAGE>   58
                                                                              53

question ("underpaid Producers"), the Accountants are required to instruct the
Bontang VI Trustee to pay to the underpaid Producers, pro rata in proportion to
the excess amount borne by each such Producer, all amounts otherwise payable
under Article 8 to the Producers which have borne less than their Aggregate
Dollar Shares for the period in question until the aggregate amount received by
each of the underpaid Producers from the Allocation Trustees (as shown by the
notices referred to in the last sentence of this paragraph and all similar
notices received from the other Allocation Trustees) equals the amount stated
in such instructions to be the excess amount borne by such Producer.  The
Bontang VI Trustee shall promptly advise each other Allocation Trustee of each
such payment pursuant to this Section 12.3.

                 Upon receipt of any such instructions the Bontang VI Trustee
shall give effect thereto commencing with the next payments to Producers
pursuant to Article 8.

                 12.4  Pro Rata Treatment.  In the event that the funds
available for making the payments required by Sections 12.2 and 12.3 shall not
be sufficient to make the payments therein required in full, such funds shall
be paid to the Producers entitled to payments pursuant to such Sections pro
rata in proportion to the amounts payable to each such Producer thereunder.

                 12.5  Income From the Disbursement Trust.  In order to
implement the provisions of Section 2.4 of the Debt Service Allocation
Agreement, upon receipt of instructions from the Accountants, which shall state
that they are issued pursuant to said Section, and receipt from the
Disbursement Trustee of the funds specified in such instructions, the Bontang
VI Trustee shall distribute the funds so received as specified in such
instructions.

Each of VICO, Total and Unocal is hereby designated the sole representative of
the Contractors comprising its respective Contractor Group for the giving and
receipt of notices, approvals, instructions and other communications to or from
the Contractors under this Agreement and, to the extent Contractors are
entitled to give or receive notices, approvals or instructions thereunder, the
Other Trust Agreements.  For purposes of the foregoing, unless specifically
provided otherwise and, with respect to Inpex, solely until March 31, 1997,
each reference in this Agreement to the Producers or the Contractors, shall,
insofar as the Contractors are concerned, require notices, approvals and other
communications to and from such representatives. On and following March 31,
1997, each reference to the Producers or the Contractors shall, insofar as
Inpex is concerned, require notices, approvals and other communications to and
from Inpex.  A new or successor representative may be designated by notice to
such effect signed by all the Contractors comprising a Contractor Group given
to the parties to this Agreement ten days in advance of any such change.  Until
receipt of any such notice, the parties to this Agreement and the Other Trust
Agreements may rely on any notice, approval, instruction or other communication
from or to the representative of a Contractor Group as binding upon each of the
Contractors in such Contractor Group; provided, however, that, except as
provided in Section 8.5, nothing in this Agreement is intended to grant the
representative of a Contractor Group (or any successor representative
designated pursuant to this Section 13.3) any power or authority as among the
Contractors in such Contractor Group themselves.

                 The parties may designate additional addresses for particular
communications as required from time to time, and may change any address, by
notice given 10 days in advance of such additions or changes.  Immediately upon
receiving communications by telex or telecopier a party may request a repeat
transmittal of the entire communication or confirmation of particular matters.

                 Except as otherwise specified in this Agreement, all notices
and other communications shall be deemed to have been duly given on (i) the
date of delivery if delivered personally at or before 5:00 p.m. on the date of
delivery in the time zone of the recipient (otherwise on the day immediately
following the date of delivery), (ii) five days following posting if
transmitted by mail, (iii) the date of transmission if transmitted by telex
with confirmed answerback received at or before 5:00 p.m. on the date of
transmission in the time zone of the recipient (otherwise on the day
immediately following the date of transmission) or (iv) the date of receipt of
a legible copy thereof if

sent by telecopier received at or before 5:00 p.m. on the date of transmission
in the time zone of the recipient (otherwise on the day immediately following
the date of receipt), whichever shall first occur.

                 Any notice to or from the Agent under the Loan Agreement shall
be given in accordance with this Section 13.3, addressed, if to the Agent, at
the address set forth in the Loan Agreement.

                 13.4  Incumbency Certificates; Notices.

                          (a)     Pertamina and each representative of a
Contractor Group (or any successor representative of a Contractor designated
pursuant to Section 13.3) shall each furnish the Bontang VI Trustee, from time
to time, with duly executed incumbency certificates showing the names, titles,
and specimen signatures of the persons authorized on behalf of such party to
give the notifications and approvals required by this Agreement.

                          (b)     The Producers shall arrange for the
Accountants to provide the Bontang VI Trustee from time to time with a
notification signed by two of the Accountants' partners, advising the Bontang
VI Trustee of the name and title, and furnishing a specimen signature, of the
person or persons authorized to execute the certificates and other documents
required by this Agreement.

                          (c)     Each Producer shall, and the Producers shall
cause the Accountants to, agree with the Bontang VI Trustee upon "test-key"
arrangements for the purpose of authenticating communications between them
respectively which authorize, accomplish, direct or otherwise deal with the
transfer of money under this Agreement.  If the Bontang VI Trustee or any
Producer receives such a communication which does not comply with such
arrangements, such recipient shall notify the sender of such failure to comply,
requesting correction thereof, and shall take no action in accordance with such
communication until such correction is effected.

                          (d)     Each of the Contractors shall furnish the
Bontang VI Trustee, from time to time, with such certificates or other evidence
as the Bontang VI Trustee may reasonably require showing the names, titles, and
specimen signatures of the persons authorized on behalf of such party to make
the payment arrangements contemplated by Section 8.4.  Each Contractor shall
also furnish the Bontang VI Trustee, from time to time, with such Contractor's
address to which the reports required by Section 9.2 shall be sent.

                          (e)     The Bontang VI Trustee shall furnish the
Producers with notice of the officers of the Bontang VI Trustee who are
