                 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






                                     -22-
   29
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.

   30
                 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 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






                                     -24-
   31
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.

                 (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






                                     -25-
   32
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 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 any Obligor 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 April 15, 1997.

                 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 the Margin Increase Condition
exists and the Additional Margin Increase Condition does not exist, 1/8% plus
(iii) at such times as the Additional Margin Increase Condition exists, 1/4%
plus (iv) 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) 0.6875% plus (ii) the applicable London Interbank Offered Rate plus (iii)
at such times as the Margin Increase Condition exists and the Additional Margin
Increase Condition does not exist, 1/8% plus (iv) at such times as the
Additional Margin Increase Condition exists, 1/4% plus (v) at such times as any
Event of Default exists, 1%; provided that any overdue






                                     -26-
   33
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 (i) the sum of 0.6875% plus the London Interbank
Offered Rate applicable to such Loan plus at such times as the Margin Increase
Condition exists and the Additional Margin Increase Condition does not exist,
1/8% plus at such times as the Additional Margin Increase Condition exists,
1/4% and (ii) the sum of (1) 0.6875% plus (2) 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 (3) at such times as the
Margin Increase Condition exists and the Additional Margin Increase Condition
does not exist, 1/8% plus (4) at such times as the Additional Margin Increase
Condition exists, 1/4% (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 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






                                     -27-
   34
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.  Fees.  (a) During the Revolving Credit Period,
the Company shall pay to the Agent for the account of the Banks ratably in
proportion to their Commitments a commitment fee at a rate per annum equal to

Commitments exceed the aggregate outstanding principal amount of the Loans.
Such commitment fee shall accrue from and including the Effective Date to but
excluding the Termination Date.  Additionally, the Company shall pay to the
Agent for the account of the Banks ratably a facility fee at a rate per annum
equal to 0.1875% on the daily average aggregate outstanding principal amount of
the Loans.  Such facility fee shall accrue from and including the Effective
Date to but excluding the date the Loans shall be repaid in their entirety.

                 (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 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






                                     -28-
   35
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.

                 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






                                     -29-
   36
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 any Obligor 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.

                 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






                                     -30-
   37
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 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






                                     -31-
   38
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 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, any of the Notes or the Subsidiary Guaranty
Agreement (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.






                                     -32-
   39
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 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






                                     -33-
   40
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 III

                                   CONDITIONS

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                 The Company represents and warrants that:

                 SECTION 4.01.  Corporate Existence and Power.  Each of the
Obligors 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 each Obligor of each
Financing Document to which it is shown as being a party are within such
Obligor'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 such Obligor or of any instrument or agreement evidencing or governing Debt
or any other material agreement, judgment, injunction, order, decree or other
instrument binding upon such Obligor 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 each Obligor 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






                                     -36-
   43
binding agreements of the Company, and the Subsidiary Guaranty Agreement has
been duly executed and delivered by each Required Guarantor and constitutes a
legal, valid and binding obligation of each Required Guarantor.

                 SECTION 4.04.  Information.

                 (a)      The consolidated balance sheet of the Company and its
Consolidated Subsidiaries as of December 31, 1994 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 and set
forth in the Company's 1994 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 1994 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.  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 any Obligor to perform its obligations under
the Financing Documents.

                 (d)      Since December 31, 1994 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






                                     -37-

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.

                 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.  The list
of entities under the caption "Subsidiary Guarantors" on the signature pages of
the Subsidiary Guaranty Agreement constitutes a true, complete and accurate
list of all Required Guarantors as of the date of this Agreement.  Part A of
Schedule II hereto contains a true, complete and accurate list of






                                     -38-
   45
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, 1989, 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 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.

                 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.

                 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






                                     -55-
   62
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 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:






                                     -56-
   63
                 (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.

                 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).






                                     -57-
   64
                 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

                 (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.






                                     -58-
   65
                 (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 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






                                     -59-
   66
         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.

                                   ARTICLE IX

                                 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.

   67
                 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 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






                                     -61-
   68
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 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






                                     -62-
   69
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; provided further
that no such amendment or waiver shall amend or waive Section 5.05(a) or any of
the definitions relevant to Section 5.05(a) unless signed by Banks having at
least 66-2/3% of the aggregate amount of the Commitments or, if the Commitments
shall have been terminated, holding Notes evidencing at least 66-2/3% of the
aggregate unpaid principal amount of the Loans.

                 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 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






                                     -63-
   70
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

         the provisions of this paragraph, constitute a legal or equitable
         discharge of the obligations of a Subsidiary Guarantor under this
         Article II.

         SECTION 2.03.    Discharge; Reinstatement in Certain Circumstances.
Subject to Section 2.08, each Subsidiary Guarantor's obligations under this
Article II shall remain in full force and effect until all of the Commitments
shall have been terminated in their entirety and the Guaranteed Amounts shall
have been paid in full.  If at any time any payment of or any amount payable by
the Company or any Subsidiary Guarantor in respect of any Guaranteed Amount is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy or reorganization of such Person or otherwise, each Subsidiary
Guarantor's obligations under this Article II with respect to such payment
shall be reinstated at such time as though such payment had become due but had
not been made at such time.

         SECTION 2.04.    Waiver.  Each Subsidiary Guarantor irrevocably waives
acceptance hereof, presentment, demand, protest and any notice not provided for
herein, as well as any requirement that at any time any action be taken by any
Person against the Company or any other Subsidiary Guarantor or any other
Person.  Each Subsidiary Guarantor hereby irrevocably waives each and every
right to which it may be entitled by virtue of the suretyship laws of the State
of Texas, including, without limitation, any and all rights it may have
pursuant to Rule 31 or Rule 32, Texas Rules of Civil Procedure, Section 17.001
of the Texas Civil Practice and Remedies Code and Chapter 34 of the Texas
Business and Commerce Code.

         SECTION 2.05.    Subrogation and Contribution.  Each Subsidiary
Guarantor irrevocably waives any and all rights to which it may be entitled, by
operation of law or otherwise, upon making any payment hereunder (i) to be
subrogated to the rights of the payee against the Company with respect to such
payment or otherwise to be reimbursed, indemnified or exonerated by the Company
in respect thereof or (ii) to receive any payment, in the nature of
contribution or for any other reason, from any other Obligor with respect to
such payment, in each case until such time as all of the






   93
Commitments shall have been terminated in their entirety and the Guaranteed
Amounts shall have been paid in full.

         SECTION 2.06.    Stay of Acceleration.  If acceleration of the time
for payment of any amount payable by the Company or any Subsidiary Guarantor in
respect of any Guaranteed Amount is stayed upon the insolvency, bankruptcy or
reorganization of such Person, all such amounts otherwise subject to
acceleration under the terms of the Credit Agreement or any other agreement or
instrument evidencing such Guaranteed Amount shall nonetheless be payable by
each other Subsidiary Guarantor hereunder forthwith on demand by the Agent.

         SECTION 2.07.    Representations and Warranties.   Each Subsidiary
Guarantor represents and warrants that as of the date hereof, and after giving
effect to this Agreement and the contingent obligations evidenced hereby
(including any limitation on the amount payable under this Agreement pursuant
to Section 2.08), it is and will be solvent, and has and will have assets
which, fairly valued, exceed its obligations, liabilities and debts, and has
and will have property and assets sufficient to satisfy and repay its
obligations, liabilities and debts when the same become due.

         SECTION 2.08.    Limit of Liability.  Each Subsidiary Guarantor shall
be liable under this Agreement only for amounts aggregating up to the largest
amount that would not render its obligations hereunder subject to avoidance
under Section 548 of the United States Bankruptcy Code or any comparable
provisions of any applicable state or foreign law.


                                  ARTICLE III

                                 MISCELLANEOUS

         SECTION 3.01.    Notices.  All notices, requests and other
communications to any party hereunder shall be in writing (including telecopy,
telex, facsimile transmission or similar writing) and (i) in the case of a
Subsidiary Guarantor, shall be given to such Subsidiary Guarantor at c/o Union
Texas Petroleum Holdings, Inc., 1330 Post Oak Boulevard, Houston, Texas 77056
(telex number:  762255) and (ii) in the case of the Company or the Agent, at
its address or telex number set forth on the signature pages of the Credit
Agreement or in any case at 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 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 or (iii) 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.






   94
         SECTION 3.02.    No Waiver; Exercise of Remedies.  No failure or delay
by the Agent in exercising any right, power or privilege hereunder 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 herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.  In
exercising the rights and remedies herein provided, the Agent shall act at the
instructions of the Required Banks or, failing such instruction, at its
discretion.

         SECTION 3.03.    Amendments and Waivers.  Any provision of this
Agreement may be amended or waived, and any Subsidiary Guarantor may be
released from any of its obligations hereunder, if, and only if, such
amendment, waiver or release is in writing and is signed by (i) each Subsidiary
Guarantor affected thereby and (ii) the Agent with the consent of Banks at the
time having at least 66-2/3% of the aggregate amount of the Commitments or, if
the Commitments shall have been terminated, holding Notes evidencing at least
66-2/3% of the aggregate unpaid principal amount of the Loans; provided that
any Subsidiary Guarantor shall be released from its obligations hereunder upon
the terms set forth in Section 5.10 or Section 5.20 of the Credit Agreement.

         SECTION 3.04.    Texas Law.  This Agreement shall be construed in
accordance with and governed by the law of the state of Texas.

         SECTION 3.05.    CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  EACH
SUBSIDIARY GUARANTOR HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE
JURISDICTION OF THE COURTS OF THE STATE OF TEXAS AND OF ANY FEDERAL COURT
LOCATED IN SUCH STATE OVER EACH OF THEM IN CONNECTION WITH ANY ACTION, SUIT 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, SUIT OR PROCEEDING
SHALL BE IN THE STATE OF TEXAS.  IN ANY SUCH ACTION, SUIT OR PROCEEDING, EACH
SUBSIDIARY GUARANTOR WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER
PROCESS OR NOTICE AND AGREES THAT SERVICE BY FIRST CLASS MAIL, RETURN RECEIPT
REQUESTED, TO SUCH SUBSIDIARY GUARANTOR 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 CONSTITUTE GOOD AND SUFFICIENT SERVICE UPON SUCH
SUBSIDIARY GUARANTOR.  EACH SUBSIDIARY GUARANTOR THAT IS NOT ORGANIZED UNDER
THE LAWS OF THE UNITED STATES OR A STATE THEREOF (EACH A "NON-U.S. GUARANTOR")
HEREBY APPOINTS THE PRINCIPAL OFFICE OF CT CORPORATION SYSTEM IN HOUSTON,
TEXAS, WHICH, ON THE DATE HEREOF, IS LOCATED AT 911 DALLAS STREET, HOUSTON,
TEXAS  77002, AS THE AUTHORIZED AGENT THEREOF (THE "AUTHORIZED AGENT") UPON
WHOM PROCESS MAY BE SERVED IN ANY SUCH






   95
ACTION, SUIT OR PROCEEDING WHICH MAY BE INSTITUTED IN THE STATE OF TEXAS.  SUCH
APPOINTMENT SHALL BE IRREVOCABLE UNLESS AND UNTIL THE APPOINTMENT OF A
SUCCESSOR AUTHORIZED AGENT FOR SUCH PURPOSE, AND SUCH SUCCESSOR'S ACCEPTANCE OF
SUCH APPOINTMENT, SHALL HAVE OCCURRED AND THE AGENT SHALL HAVE BEEN NOTIFIED
THEREOF.  EACH NON-U.S. GUARANTOR AGREES TO TAKE ANY AND ALL ACTIONS,
INCLUDING, WITHOUT LIMITATION, THE FILING OF ANY AND ALL DOCUMENTS AND
INSTRUMENTS, THAT MAY BE NECESSARY TO CONTINUE SUCH APPOINTMENT IN FULL FORCE
AND EFFECT AS AFORESAID.  SERVICE OF PROCESS UPON THE AUTHORIZED AGENT WITH
RESPECT TO ANY SUCH ACTION, SUIT OR PROCEEDING SHALL BE DEEMED, IN EVERY
RESPECT, EFFECTIVE SERVICE OF PROCESS UPON ANY SUCH NON-U.S. GUARANTOR.  EACH
NON-U.S. GUARANTOR SHALL REQUIRE THE AUTHORIZED AGENT TO AGREE IN WRITING TO
ACCEPT THE FOREGOING APPOINTMENT AS AGENT FOR SERVICE OF PROCESS.

         SECTION 3.06.    WAIVER OF JURY TRIAL.    EACH SUBSIDIARY GUARANTOR
HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

         SECTION 3.07.    WAIVER OF SOVEREIGN IMMUNITY.  TO THE EXTENT THAT ANY
SUBSIDIARY GUARANTOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM
JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR
NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION, EXECUTION
OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, SUCH SUBSIDIARY GUARANTOR
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT IT MAY LEGALLY DO SO, SUCH
IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND, WITHOUT
LIMITING THE GENERALITY OF THE FOREGOING, AGREES, TO THE FULLEST EXTENT IT MAY
LEGALLY DO SO, THAT THE WAIVERS SET FORTH IN THIS SECTION 3.07 SHALL HAVE THE
FULLEST SCOPE PERMITTED UNDER THE FOREIGN SOVEREIGN IMMUNITIES ACT OF 1976 OF
THE UNITED STATES AND ARE INTENDED TO BE IRREVOCABLE FOR PURPOSES OF SUCH ACT.

         SECTION 3.08.    Successors and Assigns.

                 (a)      All of 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 no Subsidiary Guarantor
         may assign or transfer any of its rights or obligations under this
         Agreement.

                 (b)      Any Subsidiary may become a party hereto and a
         Subsidiary Guarantor hereunder, without any further action by any
         other party, by executing and delivering a counterpart hereof to the
         Agent.






   96
         SECTION 3.09.    Counterparts.  This Agreement may be signed in any
number of counterparts, each of which shall be an original, and all of which
taken together shall constitute a single instrument, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

         SECTION 3.10.  Judgment Currency.  Each Non-U.S. Guarantor agrees to
indemnify the Agent and each Bank against any loss incurred by it as a result
of any judgment or order being given or made and expressed and paid in a
currency (the "Judgment Currency") other than United States dollars and as a
result of any variation as between (i) the rate of exchange at which the United
States dollar amount is converted into the Judgment Currency for the purpose of
such judgment or order and (ii) the spot rate of exchange in The City of New
York at which the Agent or such Bank on the date of payment of such judgment or
order is able to purchase United States dollars with the amount of the Judgment
Currency actually received by the Agent or such Bank.  The foregoing indemnity
shall constitute a separate and independent obligation of each Non-U.S.
Guarantor and shall continue in full force and effect notwithstanding any such
judgment or order as aforesaid.  The term "spot rate of exchange" shall include
any premiums and costs of exchange payable in connection with the purchase of,
or conversion into, United States dollars.

         SECTION 3.11.  Existence.  Each Subsidiary Guarantor agrees to
maintain its existence except as permitted by Section 5.02 of the Credit
Agreement.

         SECTION 3.12.    Taxes.  (a)  Any and all payments by any Subsidiary
Guarantor hereunder shall be made 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 any Subsidiary
Guarantor shall be required by law to deduct any Taxes from or in respect of
any sum payable hereunder to any Bank, any Co-Agent or the Agent, (i) the sum
payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 3.12) 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) such Subsidiary Guarantor shall make such deductions
and (iii) such Subsidiary Guarantor shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
law.






   97
         (b)     Each Subsidiary Guarantor will indemnify each Bank, each
Co-Agent and the Agent for the full amount of Taxes (including, without
limitation, any Taxes imposed by any jurisdiction on amounts payable under this
Section 3.12) 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 were correctly or
legally asserted.  Payments under any indemnification provided for in this
Section 3.12(b) 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.

         (c)     Within 30 days after the date of any payment of Taxes by a
Subsidiary Guarantor, such Subsidiary Guarantor will furnish to the Agent, at
its address referred to in Section 9.01 of the Credit Agreement, 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 a Subsidiary Guarantor of
Taxes as required by this Section 3.12 (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 such Subsidiary
Guarantor 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.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed by their respective authorized officers as of the date first
above written.

                           OPINION OF GENERAL COUNSEL

                                 April 24, 1995


To the Banks and the Agent
 Referred to Below
c/o NationsBank of Texas, N.A., as Agent
700 Louisiana Street
Houston, Texas 77002

Dear Sirs:

                 I am General Counsel, Vice President-Administration, and
Secretary of Union Texas Petroleum Holdings, Inc., a Delaware corporation (the
"Company"), and have acted as counsel (i) for the Company in connection with
the Credit Agreement dated as of April 24, 1995 (the "Credit Agreement") among
the Company, the Banks and Co-Agents listed on the signature pages thereof and
NationsBank of Texas, N.A., as Agent (the "Agent"), and (ii) for Union Texas
Petroleum Energy Corporation, a Delaware corporation, Union Texas International
Corporation, a Delaware corporation, Unistar, Inc., a Delaware corporation,
Union Texas East Kalimantan Limited, a Bahamian corporation, and Union Texas
Products Corporation, a Delaware corporation (collectively, the "Subsidiary
Guarantors" and together with the Company, the "Obligors"), in connection with
the Subsidiary Guaranty Agreement dated as of April 24, 1995 (the "Subsidiary
Guaranty Agreement") among the Subsidiary Guarantors and the Agent.  Terms
defined in the Credit Agreement and not otherwise defined herein are used
herein as therein defined.

                 In connection with the opinions expressed below, I have
examined or caused to be examined executed counterparts of the following
(collectively, the "Financing Documents"):

                 (a)      the Credit Agreement,

                 (b)      the Subsidiary Guaranty Agreement, and

                 (c)      twenty four (24) promissory notes, each substantially
         in the form of Exhibit A to the Credit Agreement, one payable to each
         Bank.

                 I have also examined or caused to be examined originals or
copies, certified or otherwise identified to my satisfaction, of such other
instruments, documents and records as I deemed necessary to express the
opinions hereinafter set forth.  To the extent relevant to my opinion, I have
assumed, without independent verification, (i) the






                                       
   100
To the Banks and the Agent
 Referred to Below

due execution and delivery of each Financing Document by each party thereto
(other than the Obligors), (ii) the genuineness of all signatures on all
documents submitted to me, (iii) that each party (other than the Obligors) to
each of the Financing Documents is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization and has full
power and authority to enter into and to carry out its obligations under such
Financing Documents, (iv) that the execution and delivery of each of the
Financing Documents by each party thereto (other than the Obligors) and the
performance of its obligations under such Financing Documents have been duly
authorized by all necessary proceedings and actions, (v) that each of the
Financing Documents is the legal, valid and binding obligation of each party
thereto (other than the Obligors), enforceable against such party in accordance
with the terms of such Financing Documents, subject to limitations of the types
described in the opinion of Andrews & Kurth L.L.P. delivered to you pursuant to
the Financing Documents, and (vi) the authenticity of all documents submitted
to me as originals and the conformity to authentic original documents of all
documents submitted to me as certified, conformed or photostatic copies.  I
have relied, to the extent that I deem such reliance proper, upon certificates
of officers of one or more of the Obligors and of governmental officials as to
matters of fact not independently established by me.

                 For purposes of the opinion set forth in paragraph 2 below, I
have (i) relied on the opinion of Andrews & Kurth L.L.P. with respect to the
agreements and instruments identified on Schedule I thereto, and (ii) examined
or caused to be examined each other agreement or other instrument binding upon
any Obligor, a breach of or default under which would, in my judgment, have a
material adverse effect upon the Company and its Subsidiaries taken as a whole.
As to other agreements and instruments, I have not undertaken such a review for
purposes of this opinion, given the volume of such documents and given the fact
that by virtue of the character of such documents and the historical practices
of the Company with respect thereto, I have no reason to believe that a breach
of or default under any such document would arise by virtue of the execution,
delivery and performance of the Financing Documents.

                 Based on the foregoing and subject to the qualifications and
limitations set forth below, I am of the opinion that:

                 1.       Each of the Obligors has all material governmental
licenses, authorizations, consents and approvals required to own its assets and
to carry on its business as now conducted.

                 2.       To the best of my knowledge, the execution, delivery
and performance by each Obligor of each Financing Document to which it is a
party do not constitute a breach of or default under, or result in the creation
or imposition of any Lien on any material asset of the Company or any
Subsidiary under, any provision of any instrument or agreement evidencing or
governing Debt binding upon such Obligor or any other material agreement,
judgment, injunction, order, decree or other instrument binding upon such
Obligor.  However, please be advised that the Company currently has an
aggregate $300 million principal amount of its senior notes outstanding
(individually referred to as the $100 million 8.25% Senior Notes due 1999, the
$125 million 8 3/8% Senior Notes due 2005 and the $75 million 8 1/2% Seniior
Notes due 2007, and collectively referred to as the "Senior Notes"), and that
the sum of the Senior Notes, the Commitments and the commitments under the
Other Credit Agreement equals $850 million, while the total amount of debt
permitted under Section 5.05(a) of the Credit Agreement and the Other Credit
Agreement may not exceed $775 million.

                 3.       To the best of my knowledge, there is no action, suit
or proceeding pending against, 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.

                 My opinions in paragraph 1 are rendered only with respect to
the constitutions, laws, rules and regulations which are currently in effect
and applicable court rulings and orders which have been published and are
generally available.  In addition, the foregoing opinions are rendered only as
of the date hereof, and I disclaim any obligation to advise you of changes
thereafter.

                 I am a member of the bar of the State of Texas only, and this
opinion is limited in all respects to the laws of the State of Texas, the
General Corporation Law of Delaware and federal law of the United States of
America, and, to the limited extent described below, the laws of The
Commonwealth of The Bahamas and The Republic of Indonesia.  In rendering

c/o NationsBank of Texas, N.A., as Agent

Houston, Texas 77002

Dear Sirs:

                 We have acted as special counsel (i) to Union Texas Petroleum
Holdings, Inc., a Delaware corporation (the "Company"), in connection with the
Credit Agreement dated as of April 24, 1995 (the "Credit Agreement") among the
Company, the Banks and Co-Agents listed on the signature pages thereof and
NationsBank of Texas, N.A., as Agent (the "Agent"), and (ii) to Union Texas
Petroleum Energy Corporation, a Delaware corporation, Union Texas International
Corporation, a Delaware corporation, Unistar, Inc., a Delaware corporation,
Union Texas East Kalimantan Limited, a Bahamian corporation, and Union Texas
Products Corporation, a Delaware corporation (collectively, the "Subsidiary
Guarantors" and together with the Company, the "Obligors"), in connection with
the Subsidiary Guaranty Agreement dated as of April 24, 1995 (the "Subsidiary
Guaranty Agreement") among the Subsidiary Guarantors and the Agent.  Terms
defined in the Credit Agreement and not otherwise defined herein are used
herein as therein defined.

                 In connection with the opinions expressed below, we have
examined executed counterparts of the following (collectively, the "Financing
Documents"):

                 (a)      the Credit Agreement,

                 (b)      the Subsidiary Guaranty Agreement, and

                 (c)      twenty four (24) promissory notes, each substantially
         in the form of Exhibit A to the Credit Agreement, one payable to each
         Bank (collectively, the "Notes").

                 We have also examined originals or copies, certified or
otherwise identified to our satisfaction, of such other instruments, documents
and records as we deemed necessary to express the opinions hereinafter set
forth.  To the extent relevant to our opinion, we have assumed, without
independent verification, (i) the due execution and delivery of each Financing
Document by each party thereto (other than the

Obligors), (ii) the genuineness of all signatures on all documents submitted to
us, (iii) that each party (other than the Obligors) to each of the Financing
Documents is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization and has full power and authority
to enter into and to carry out its obligations under such Financing Documents,
(iv) that the execution and delivery of each of the Financing Documents by each
party thereto (other than the Obligors) and the performance of its obligations
under such Financing Documents have been duly authorized by all necessary
proceedings and actions, (v) that each of the Financing Documents is the legal,
valid and binding obligation of each party thereto (other than the Obligors)
enforceable against such party in accordance with the terms of such Financing
Documents, subject to limitations of the types described herein, and (vi) the
authenticity of all documents submitted to us as originals and the conformity
to authentic original documents of all documents submitted to us as certified,
conformed or photostatic copies.  We have relied, to the extent that we deem
such reliance proper, upon certificates of officers of one or more of the
Obligors and of governmental officials as to matters of fact not independently
established by us.  We have also examined the representations and warranties of
the Company contained in the Credit Agreement and have relied, to the extent we
deem such reliance proper, upon the relevant facts stated therein.

                 Based on the foregoing and subject to the qualifications and
limitations set forth below, we are of the opinion that:

                 1.       (a)     Each of the Obligors is a corporation duly
incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has all corporate power and authority
required to own its assets and to carry on its business as now conducted.

                 (b)      The execution, delivery and performance by each
Obligor of each Financing Document to which it is a party will not violate the
Public Utility Holding Company Act of 1935, the Investment Company Act of 1940
or the Interstate Commerce Act.

                 2.       The execution, delivery and performance by each
Obligor of each Financing Document to which it is a party are within such
Obligor's corporate powers, have been duly authorized by all necessary
corporate action, and do not constitute a breach or default under, any
provision of applicable law or regulation known to us after reasonable inquiry
or the certificate of incorporation or bylaws of such Obligor.

                 3.       To the best of our knowledge, the execution, delivery
and performance by each Obligor of each Financing Document to which it is a
party do not constitute a breach of or default under, or result in the creation
or imposition of any Lien on any material asset of the Company or any
Subsidiary under, any provision of the instruments and agreements identified in
Schedule I hereto.  However, please be advised that the Company currently has
an aggregate $300 million principal amount of its senior notes outstanding
(individually referred to as the $100 million 8.25% Senior Notes due 1999, the
$125 million 8 3/8% Senior Notes due 2005 and the $75 million 8 1/2% Senior
Notes due 2007, and collectively referred to as the "Senior Notes"), and that
the sum of the Senior Notes, the Commitments and the commitments under the
Other Credit Agreement equals $850 million, while the total amount of debt
permitted under Section 5.05(a) of the Credit Agreement and the Other Credit
Agreement may not exceed $775 million.

                 4.       No authorization, consent or approval of any
governmental body, agency or official is required in connection with the
execution, delivery or performance by any Obligor of any of the Financing
Documents to which it is a party.

                 5.       (a)     The Credit Agreement and the Notes have been
duly executed and delivered by the Company, and constitute legal, valid and
binding obligations of the Company, enforceable against the Company in
accordance with their respective terms.

                 (b)      The Subsidiary Guaranty Agreement has been duly
executed and delivered by each of the Subsidiary Guarantors, and constitutes a
legal, valid and binding obligation of each of the Subsidiary Guarantors,
enforceable against each of the Subsidiary Guarantors in accordance with its
terms.

                 6.       If all material facts (as we understand them) and
issues of law were presented and properly argued, a Texas court or a federal
court sitting in the State of Texas and applying the laws of the State of Texas
should hold that the consent by the Company in Section 9.09 of the Credit
Agreement, and by each Subsidiary Guarantor in Section 3.05 of the Subsidiary
Guaranty Agreement, to the non-exclusive personal jurisdiction of the courts of
the State of Texas and of any federal court located in the State of Texas is
valid.  In this regard we call to your attention that such consents to
non-exclusive jurisdiction are not effective to (1) confer subject matter
jurisdiction that does not otherwise exist in such court or (2) establish
diversity jurisdiction that does not otherwise exist in an action brought in
federal court.

                 7.       Neither the execution, delivery and performance by
any Obligor of the Financing Documents to which it is a party, nor the use of
the proceeds of the Loans in accordance with Section 5.09 of the Credit
Agreement, will violate the provisions of Regulations G, T, U or X of the Board
of Governors of the Federal Reserve System.

                 The opinions set forth above are subject to the following
additional assumptions, limitations and qualifications:

                 (a)      Our opinions with respect to the enforceability of
the Financing Documents are subject to the qualification that such
enforceability may be (i) limited by applicable bankruptcy, insolvency,
reorganization, fraudulent transfer, moratorium or similar laws affecting the
rights of creditors generally, (ii) subject to general principles of equity
(regardless of whether such enforceability is considered in a proceeding at law
or in equity), including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing, and (iii) limited by the power of
a court to award damages in lieu of equitable remedies (including specific
performance or injunctive relief) or otherwise to refuse to grant a particular
remedy sought by the parties to the Financing Documents.

                 (b)      We express no opinion herein as to (1) the right of
any Bank to set-off against funds held in any special account maintained by the
Company with such Bank or which are otherwise subject to special agreement
between the Company and such Bank; (2) whether the provisions of the Credit
Agreement which permit the Agent, the Co-Agents or any Bank to take action or
make determinations may be subject to a requirement that such action be taken
or such determination be made in good faith; (3) whether the holder of a Note
may, under certain circumstances, be called upon to prove the outstanding
principal amount of the loans evidenced thereby; (4) the effect of the law of
any jurisdiction (other than Texas) wherein any Bank may be located which
limits rates of interest which may be charged or collected by such Bank; and
(5) the enforceability of any provision in the Financing Documents that
purports to (i) require indemnification for the negligence or wilful misconduct
of the indemnitee or to otherwise require any Obligor to provide
indemnification to the extent the same may be in conflict with public policy,
(ii) limit the effect of any delay or omission of enforcement of rights or
remedies or any course of performance or course of dealing between the parties,
(iii) create an agreement to agree, (iv) fix evidentiary standards or venue of
any proceeding, (v) waive rights to a trial by jury, or (vi) waive rights to
notices, legal defenses or other benefits that cannot, as a matter of law, be
effectively waived.

                 (c)      Whenever this opinion states the existence or absence
of any fact to the best of our knowledge, such statement is intended to convey
that, during the course of our representation of the Obligors with respect to
matters addressed herein, no information has come to our attention which has
given us actual knowledge of facts contrary to the statements so expressed
herein.

                 (d)      In rendering our opinions in paragraph 1 we have
relied upon the description of the properties, assets and businesses of the
Obligors set forth in the Report on Form 10-K for the year ended December 31,
1994, filed by the Company with the Securities and Exchange Commission.

                 (e)      In rendering the opinions in paragraphs 2 and 5, we
have assumed that (i) there are no fees, points, premiums or other sums
contracted for, charged to or paid or to be paid by the Company to the Banks on
account of the transactions described in the Credit Agreement other than those
described in the Credit Agreement and those described in the letters of even
date herewith from the Agent to us and (ii) the parties to the Financing
Documents will comply strictly with the precise terms of the Financing
Documents, including, without limitation, the usury savings clauses set forth
therein with respect to any consideration contemplated by the Financing
Documents that will constitute interest under Texas law.

                 (f)      In rendering our opinions in paragraph 7 we have
assumed that the representations of the Company and the Banks set forth in
Sections 4.12 and 9.07, respectively, of the Credit Agreement will be true and
correct at all times.

                 (g)      The foregoing opinions are rendered only with respect
to the constitutions, laws, rules and regulations which are currently in effect
and applicable court rulings and orders which have been published and are
generally available.  In addition, the foregoing opinions are rendered only as
of the date hereof, and we disclaim any obligation to advise you of changes
thereafter.

State of Texas, the General Corporation Law of Delaware and federal law of the
United States of America, and, to the limited extent described below, the laws

                                 April 24, 1995



To NationsBank of Texas, N.A., as Agent,
  and to each of the Banks referred to below

Ladies and Gentlemen:

We have acted as special counsel to NationsBank of Texas, N.A., acting for
itself and as Agent, in connection with the preparation, execution and delivery
of the Credit Agreement dated as of April 24, 1995 (the "Credit Agreement")
among Union Texas Petroleum Holdings, Inc., a Delaware corporation (the
"Company"), the banks listed on the signature pages thereof (the "Banks"),
NationsBank of Texas, N.A., as Agent (the "Agent"), and the Co-Agents.
Capitalized terms defined in the Credit Agreement and not defined herein are
used herein as therein defined.

In that connection, we have examined counterparts of the Credit Agreement
executed by the Agent and the Company respectively and the following documents:

       (1)    The Notes delivered to the Agent on the date hereof.

       (2)    The Subsidiary Guaranty Agreement delivered to the Agent on the
              date hereof.

       (3)    The legal opinions delivered to the Agent pursuant to Sections
              3.01(d), 3.01(e) and 3.01(g) of the Credit Agreement.

In our examination of the documents referred to above, we have assumed the
authenticity of all such documents submitted to us as originals, the
genuineness of all signatures and the conformity to the originals of all such
documents submitted to us as copies.  We have also assumed the accuracy of all
matters set forth in the certificates delivered to the Agent on the date hereof
in connection with the Credit Agreement and assumed that each of Company, the
Banks, the Agent and the Co-Agents has duly executed and delivered, with all
necessary power and authority (corporate and otherwise), the Credit Agreement,
that the Company has duly executed and delivered, with all necessary power and
authority (corporate and otherwise), the respective Notes, and that each of the
Required Guarantors and the Agent has duly executed and delivered, with all
necessary power and authority (corporate and otherwise), the Subsidiary
Guaranty Agreement.  We have also assumed that no Bank has requested multiple
Notes pursuant to Section 2.05(b) of the Credit Agreement.

other investigation as we have deemed necessary, we are of the opinion that the
documents referred to in items (1), (2) and (3) above are substantially
responsive to the requirements of the Credit Agreement.

                              W I T N E S S E T H:

              WHEREAS, this Assignment and Assumption Agreement (this
"Agreement") relates to the Credit Agreement dated as of April 24, 1995 among
the Company, the Banks (including Assignor) and Co-Agents parties thereto and
the Agent (such Credit Agreement, as amended from time to time, is hereinafter
referred to as the "Credit Agreement");

              WHEREAS, as provided under the Credit Agreement, the Assignor has
a Commitment to make Loans in an aggregate principal amount at any time
outstanding not to exceed $____________;

              WHEREAS, Loans made by the Assignor under the Credit Agreement in
the aggregate principal amount of $_____________ are outstanding at the date
hereof; and

              WHEREAS, the Assignor proposes to assign to the Assignee all of
the rights of the Assignor under the Credit Agreement in respect of a portion
of its Commitment thereunder in an amount equal to $__________ (the "Assigned
Amount"), together with a corresponding portion of its outstanding Loans, and
the Assignee proposes to accept assignment of such rights and assume the
corresponding obligations from the Assignor on such terms;

              NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

              SECTION 1.  Definitions.  All capitalized terms not otherwise

Agreement.

              SECTION 2.  Assignment.  The Assignor hereby assigns and sells to
the Assignee all of the rights of the Assignor under the Credit Agreement to
the extent of the Assigned Amount, and the Assignee hereby accepts such
assignment from the Assignor and assumes all of the obligations of the Assignor

purchase from the Assignor of the corresponding portion of the principal amount
of the Loans made by the Assignor outstanding at the date hereof.  Upon the
execution and delivery hereof by the Assignor,






                                       
   117
the Assignee[, the Company] and the Agent and the payment of the amounts
specified in Section 3 required to be paid on the date hereof, (i) the Assignee
shall, as of the date hereof, succeed to the rights and be obligated to perform
the obligations of a Bank under the Credit Agreement with a Commitment in an
amount equal to the Assigned Amount plus the amount of the Commitment, if any,
of the Assignee immediately prior to the effectiveness of this Agreement, and
(ii) the Commitment of the Assignor shall, as of the date hereof, be reduced by
an amount equal to the Assigned Amount, and the Assignor shall, as of the date
hereof, be released from its obligations under the Credit Agreement to the
extent such obligations have been assumed by the Assignee.  The assignment
provided for herein shall be without recourse to the Assignor.  The Assignor
hereby certifies that after giving effect to this Agreement, the Assignor will
be in compliance with the last sentence of Section 9.06(c) of the Credit
Agreement.  [The Assignor and the Assignee hereby certify that the Assignee is
[an affiliate of the Assignor/another Bank,] and accordingly, the Company's
consent hereto is not required.]

              SECTION 3.  Payments.  As consideration for the assignment and
sale contemplated in Section 2 hereof, the Assignee shall pay to the Assignor
on the date hereof in Federal funds an amount equal to $__________*.  It is
understood that commitment and/or facility fees accrued to the date hereof are
for the account of the Assignor and such fees accruing from and including the
date hereof are for the account of the Assignee.  Each of the Assignor and the
Assignee hereby agrees that if it receives any amount under the Credit
Agreement which is for the account of the other party hereto, it shall receive
the same for the account of such other party to the extent of such other
party's interest therein and shall promptly pay the same to such other party.
As contemplated by Section 9.06(c) of the Credit Agreement, the Assignor agrees
to pay to the Agent for its account on the date hereof in Federal funds an
amount equal to $2,500 as an administrative fee for processing this Agreement
less any administrative processing fee paid to the Agent on the date hereof

contemporaneous assignment to the Assignee made by the Assignor under the Other
Credit Agreement pursuant to the second proviso to the first sentence of
Section 9.06(c) of the Credit Agreement.

              SECTION 4.  Consent.  This Agreement is conditioned upon the
consent of [the Company and] the Agent pursuant to Section 9.06(c) of the
Credit Agreement.  The execution of this Agreement by [the Company and] the
Agent is evidence of this consent.  Pursuant to Section 9.06(c) the Company
agrees to execute and deliver a Note payable to the order of the Assignee to
evidence the assignment and assumption provided for herein.





__________________________________

     * Amount should combine principal together with accrued interest and
breakage compensation, if any, to be paid by the Assignee, net of any portion
of any upfront fee to be paid by the Assignor to the Assignee.  It may be
preferable in an appropriate case to specify these amounts generically or by
formula rather than as a fixed sum.



                                       
   118
              SECTION 5.  Non-Reliance on Assignor.  The Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Company or any other Obligor, the validity and enforceability of the
obligations of the Company or any other Obligor in respect of the Credit
Agreement, any Note or the Subsidiary Guaranty Agreement or the accuracy of any
Engineering Report.  The Assignee acknowledges that it has, independently and
without reliance on the Assignor, and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to
enter into this Agreement and will continue to be responsible for making its
own independent appraisal of the business, affairs and financial condition of
the Company and the other Obligors, the Engineering Reports and other relevant
matters.

              SECTION 6.  Governing Law.  This Agreement shall be governed by
and construed in accordance with the laws of the State of Texas.

              SECTION 7.  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.

              SECTION 8.  Representation and Agreement.  The Assignee
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 the
Credit Agreement or the Notes.  If the Assignee is not organized under the laws
of the United States or any state thereof, it agrees to provide to the Company
and the Agent, on or prior to the date of this Agreement, two duly completed
copies of United States Internal Revenue Service Form 1001 or 4224, certifying
in either case that the Assignee is entitled to receive payments from the
Company under the Credit Agreement and the Notes without deduction or
withholding of any United States federal income taxes.

              IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their duly authorized officers as of the date first
above written.

                     OPINION OF SPECIAL INDONESIAN COUNSEL

                                 April 24, 1995


To the Banks and the Agent
  Referred to Below
c/o NationsBank of Texas, N.A. as Agent
700 Louisiana Street
Houston, Texas  77002

Dear Sirs:

              We have acted as special Indonesian counsel to Union Texas
Petroleum Holdings, Inc., a Delaware corporation (the "Company"), in connection
with the Credit Agreement dated as of April 24, 1995 (the "Credit Agreement")
among the Company, the Banks and Co-Agents listed on the signature pages
thereof and NationsBank of Texas, N.A., as Agent (the "Agent"), and to Union
Texas East Kalimantan Limited, a Bahamian corporation (the "Guarantor"), in
connection with the Subsidiary Guaranty Agreement dated as of April 24, 1995
(the "Subsidiary Guaranty Agreement") among Union Texas Petroleum Energy
Corporation, Union Texas Products Corporation, the Guarantor, Union Texas
International Corporation, Unistar, Inc. and the Agent.  Terms defined in the
Credit Agreement and not otherwise defined herein are used herein as therein
defined.

              In connection with the opinions expressed below, we have examined
the April 3, 1995 draft of the Credit Agreement and the April 3, 1995 draft of
the Subsidiary Guaranty Agreement.  We have also examined copies, certified or
otherwise identified to our satisfaction, of the Production Sharing Contracts
described in Exhibit "A" attached hereto and such other instruments, documents
and records as we have deemed necessary to express the opinions hereinafter set
forth.  We have relied, to the extent that we deem such reliance proper, upon
certificates of officers of the Guarantor as to matters of fact not
independently established by us.

              For purposes of this opinion, we have assumed the genuineness of
all signatures appearing on the documents examined by us, the authenticity of
all documents submitted to us as originals, the conformity with the original
documents of all documents submitted to us, or otherwise in our possession, as
copies, and the due authorization, execution and delivery of all such
documents.  Wherever the phrase "to the best of our knowledge" appears in this
opinion, its use reflects that we have no actual knowledge to the contrary,
that we have made due inquiry of the Guarantor, but that we have not made any
independent investigation into any of the matters to which we refer.

              Based on the foregoing, and subject to the qualifications and
limitations set forth below, we are of the opinion so far as the laws of the
Republic of Indonesia are concerned that:

              1.     The Guarantor is duly qualified as a foreign corporation
under the laws of the Republic of Indonesia, to the extent required by
Indonesian law and to the extent necessary to carry out its obligations under
the Production Sharing Contracts, and has all material governmental licenses,
authorizations, consents and approvals required to own property and assets
situated in Indonesia and to carry on business in the Republic of Indonesia in
accordance with the terms of the Production Sharing Contracts.

              2.     The execution, delivery and performance by the Guarantor
of the Subsidiary Guaranty Agreement do not constitute a breach of or default
under any provision of applicable law or regulation of the Republic of
Indonesia.

              3.     To the best of our knowledge, the execution, delivery and
performance by the Guarantor of the Subsidiary Guaranty Agreement do not
constitute a breach of or default under, or result in the creation or
imposition of any Lien on any material asset of the Guarantor under, any
judgment, injunction, order or decree of any court or governmental
instrumentality of the Republic of Indonesia binding upon the Guarantor.

              4.     No authorization, consent or approval of any Indonesian
governmental body, agency or official is required in connection with the
execution, delivery or performance by the Guarantor of the Subsidiary Guaranty
Agreement.  The Guarantor is obligated to report the execution and delivery of
the Subsidiary Guaranty Agreement to the Foreign Commercial Loan Team (the
"Team") established pursuant to Presidential Decree No. 39 of 1991 and to
deliver to the Team and to Bank Indonesia copies of the Credit Agreement and
the Subsidiary Guaranty Agreement.

              5.     To the best of our knowledge, there is no action, suit or
proceeding pending against, threatened against or affecting the Guarantor or
any of its properties or interests, at law or in admiralty or equity, before
any court, arbitrator, governmental body, agency or official of the Republic of
Indonesia.

              6.     The choice of Texas law as the proper law of the
Subsidiary Guaranty Agreement would be upheld as a valid choice of law by the
courts of the Republic of Indonesia, and the submission by the Guarantor to the
nonexclusive jurisdiction of the courts referred to in Section 3.05 of the
Subsidiary Guaranty

Agreement with respect to proceedings in connection with the Subsidiary
Guaranty Agreement would be treated by the courts of the Republic of Indonesia
as legal, valid, binding and enforceable in accordance with the terms of such
Section 3.05.  We note, however, that judgments of foreign courts are not
enforceable in Indonesia.

              7.     All amounts payable by the Guarantor under the Subsidiary
Guaranty Agreement may be made free and clear of and without deduction for or
on account of any taxes, imposts, withholdings or other deductions imposed,
assessed or levied by the Republic of Indonesia or any department, agency,
political subdivision, instrumentality or authority thereof or therein,
irrespective of the fact that the Agent or any of the Banks may have a
representative office or subsidiary in Indonesia, except that to the extent any
payments of interest and other payments in the nature of interest made by the
Guarantor under the Subsidiary Guaranty Agreement are recognized as being
effectively connected with the carrying on of the Guarantor's business in the
Republic of Indonesia, Indonesian withholding tax is payable at a rate of 20%
thereof, except where a recipient qualifies for a lower rate under a bilateral
tax treaty and an approval pursuant to the Circular Letter of the Director
General of Taxation No. SE-22/PJ.35/1993 dated August 31, 1993, has been
obtained from the Indonesian tax authorities acknowledging that the recipient
is entitled to the benefits of the treaty.

              8.     No stamp or registration duty or similar taxes or charges
are payable in the Republic of Indonesia in respect of the Subsidiary Guaranty
Agreement, except nominal stamp taxes.

              9.     Under the laws of the Republic of Indonesia, neither the
Agent nor any Bank will be deemed to be resident, domiciled or carrying on any
commercial activity in the Republic of Indonesia or, except as provided in
subparagraph 7 above, subject to any Indonesian taxes, imposts or duties as a
result only of the entry into and performance of the Subsidiary Guaranty
Agreement or the transactions contemplated thereby.

              This opinion is limited in all respects to the laws of the
Republic of Indonesia.  This opinion is for the benefit of and may be relied
upon by the Company, the Guarantor, the Banks, the Agent, the Co-Agents, their
respective successors and assigns, their respective counsel and Participants in
connection with the transactions contemplated by the Credit Agreement and may
be relied upon by Newton W. Wilson, III, General Counsel of the Company, and
Andrews & Kurth L.L.P., special counsel to the Company, in rendering their
respective opinions to the Banks and the Agent in connection with such
transactions.  Otherwise, this opinion may not be used,

Dear Sirs:

              We have acted as special Bahamian counsel to Union Texas
Petroleum Holdings, Inc., a Delaware corporation (the "Company"), in connection
with the Credit Agreement dated as of April 24, 1995 (the "Credit Agreement")
among the Company, the Banks and Co-Agents listed on the signature pages
thereof and NationsBank of Texas, N.A., as Agent (the "Agent"), and to Union
Texas East Kalimantan Limited, a Bahamian corporation (the "Guarantor") in
connection with the Subsidiary Guaranty Agreement dated as of April 24, 1995
(the "Subsidiary Guaranty Agreement") among Union Texas Petroleum Energy
Corporation, Union Texas Products Corporation, the Guarantor, Union Texas
international Corporation, Unistar, Inc. and the Agent.  Terms defined in the
Credit Agreement and not otherwise defined herein are used herein as therein
defined.

              In connection with the opinions expressed below, we have examined
the April 3, 1995 draft of the Credit Agreement and the April 3, 1995 draft of
the Subsidiary Guaranty Agreement.  We have also examined copies, certified or
otherwise identified to our satisfaction, of such other instruments, documents
and records as we have deemed necessary to express the opinions hereinafter set
forth.  We have relied, to the extent that we deem such reliance proper, upon
certificates of officers of the Guarantor as to matters of fact not
independently established by us.

              For purposes of this opinion, we have assumed the genuineness of
all signatures appearing on the documents examined by us, the authenticity of
all documents submitted to us as originals, the conformity with the original
documents of all documents submitted to us, or otherwise in our possession, as
copies, and the due authorization, execution and delivery of all such documents
(other than the Subsidiary Guaranty Agreement insofar as it relates to the
Guarantor).  Wherever the phrase "to the best of our knowledge" appears in this
opinion, its use reflects that we have no actual knowledge to the contrary,
that we have made due inquiry of the Guarantor, but that we have not made any
independent investigation into any of the matters to which we refer.

              Based on the foregoing and subject to the qualifications and
limitations set forth below, we are of the opinion that:

              1.     The Guarantor is a corporation duly organized, validly
existing and in good standing, and has all corporate power and authority and
all material governmental licenses, authorizations, consents and approvals
required to own its assets and to carry on its business as now conducted.

              2.     The execution, delivery and performance by the Guarantor
of the Subsidiary Guaranty Agreement are within the Guarantor's corporate
powers, have been duly authorized by all necessary corporate action, and do not
constitute a breach of or default under any provision of applicable law or
regulation of The Bahamas or the Memorandum of Association or the Articles of
Association of the Guarantor.

              3.     To the best of our knowledge, the execution, delivery and
performance by the Guarantor of the Subsidiary Guaranty Agreement do not
constitute a breach of or default under, or result in the creation or
imposition of any Lien on any material asset of the Company or the Guarantor
under, any judgment, injunction, order or decree of any court or governmental
instrumentality of The Bahamas binding upon the Guarantor.

              4.     No authorization, consent or approval of any Bahamian
governmental body, agency or official is required in connection with the
execution, delivery or performance by the Guarantor of the Subsidiary Guaranty
Agreement.

              5.     To the best of our knowledge, there is no pending or
threatened action, suit or proceeding before any court or any governmental
agency or body or any arbitrator in The Bahamas involving the Guarantor.

              6.     The choice of Texas law as the proper law of the
Subsidiary Guaranty Agreement would be upheld as a valid choice of law by the
courts of The Bahamas, and the submission by the Guarantor to the nonexclusive
jurisdiction of the courts referred to in Section 3.05 of the Subsidiary
Guaranty Agreement with respect to proceedings in connection with the
Subsidiary Guaranty Agreement is legal, valid, binding and enforceable in
accordance with the terms of such Section 3.05.

              7.     (a)    Any of William M. Krips, President, Larry D.
Kalmbach, Vice President, Johnnie J. Cox, Vice President, James E. Knight, Vice
President, Newton W. Wilson, III, Secretary, Michael N. Markowitz, Treasurer,
Robert V.  Deere,

Controller, Alan R. Crain, Assistant Secretary, and Luis H. Derrota, Assistant
Secretary (collectively, the "Authorized Officers") of the Guarantor has been
duly authorized to sign the Subsidiary Guaranty Agreement and any other
required documents on behalf of the Guarantor and will bind the Guarantor by
such Authorized Officer's actions.

              (b)    Upon execution and delivery of the Subsidiary Guaranty
Agreement by any Authorized Officer, the Subsidiary Guaranty Agreement will
constitute a legal, valid and binding obligation of the Guarantor enforceable
against the Guarantor in accordance with its terms, subject, as to enforcement,
to bankruptcy, insolvency, reorganization and other similar laws affecting
creditors' rights generally and to general principles of equity, and the
Subsidiary Guaranty Agreement is in proper form for its enforcement in the
courts of The Bahamas.

              8.     All amounts payable by the Guarantor under the Subsidiary
Guaranty Agreement may be made free and clear of and without deduction for or
on account of any taxes, imposts, withholdings or deductions of any kind
imposed, assessed or levied by The Bahamas or any authority thereof or therein,
irrespective of the fact that the Agent or any of the Banks may have a
representative office or subsidiary in The Bahamas.

              9.     A stamp duty of Ten dollars Bahamian currency (B$10.00) is
payable in The Bahamas in respect of the Subsidiary Guaranty Agreement.  No
other duty, tax or charge is payable in The Bahamas in respect of the
Subsidiary Guaranty Agreement.

              10.    Under the laws of The Bahamas, neither the Agent nor any
Bank will be deemed to be resident, domiciled or carrying on any commercial
activity in The Bahamas or subject to any Bahamian taxes, imposts or duties as
a result only of the entry into and performance of the Subsidiary Guaranty
Agreement or the transactions contemplated thereby.

              This opinion is limited in all respects to the laws of The
Bahamas.  This opinion is for the benefit of and may be relied upon by the
Company, the Guarantor, the Banks, the Agent, the Co-Agents, their respective
successors and assigns, their respective counsel and Participants in connection
with the transactions contemplated by the Credit Agreement and may be relied
upon by Newton W. Wilson, III, General Counsel of the Company, and Andrews &
Kurth L.L.P., special counsel to the Company, in rendering their respective
opinions to the Banks and the Agent in connection with such transactions.
Otherwise, this opinion may not be used, published,
