known structural occurrence of hydrocarbons controls the lower proved limit of
the reservoir.

    (ii)    Reserves which can be produced economically through application of
improved recovery techniques (such as fluid injection) are included in the
"proved" classification when successful testing by a pilot project, or the
operation of an installed program in the reservoir, provides support for the
engineering analysis on which the project or program was based.

    (iii)  Estimates of proved reserves do not include the following:

        (a) oil that may become available from known reservoirs but is
classified separately as "indicated additional reserves";

reasonable doubt because of uncertainty as to geology, reservoir
characteristics, or economic factors;

shales, coal, gilsonite and other such sources.

</TABLE>

   Chargeable Costs shall be subject to a maximum reduction of $1.20 per
year in years subsequent to 1995 in the following circumstances, irrespective
of whether the number of Proved Reserves added during any applicable period is
a positive number, a negative number, or zero:

   (a)  If, by December 31, 1995, 100,000,000 or more Stock Tank Barrels
(STB) of Proved Reserves have not been added to Current Reserves (before
taking into account any production therefrom) then for each year 1996 through
2000, inclusive, Chargeable Costs as set forth in the table above shall be
reduced, as of January 1 in each such year, by an amount equal to the lesser
of (A) $1.20 or (B) the product of $1.20 and a fraction, the numerator of
which shall be the difference between 100,000,000 STB of Proved Reserves and
the actual number of STB of Proved Reserves so added to Current Reserves from
January 1, 1988 through December 31, 1995, and the denominator of which shall
be 100,000,000 STB of Proved Reserves.

   (b)  If, between January 1, 1996 and December 31, 2000, an additional
200,000,000 STB of Proved Reserves (that is, 200,000,000 STB of Proved
Reserves in addition to the 100,000,000 STB of Proved Reserves that are
referred to in Section 4.4 (a)) have not been added to Current Reserves
(before taking into account any production therefrom) then for each year from
2001 through 2005, inclusive, Chargeable Costs as set forth in the table above
shall be reduced, as of January 1 in each such year, by an amount equal to the
lesser  of (A) $1.20 or (B) the product of $1.20 and a fraction, the numerator
of which shall be the difference between (1) 200,000,000 STB of Proved
Reserves and (2) the sum of (i) the actual number of STB of Proved Reserves so
added to Current Reserves from January 1, 1996 through December 31, 2000 plus
(ii) the excess, if any, of the number of STB of Proved Reserves so added to
Current Reserves from January 1, 1988 through December 31, 1995 over
100,000,000 STB of Proved Reserves (provided that the sum of (i) and (ii)
shall not exceed 200,000,000 STB of Proved Reserves), and the denominator of
which shall be 200,000,000 STB of Proved Reserves.

   (c)  The tests set forth in (i) and (ii) below shall be utilized to
calculate the reduction, if any, in Chargeable Costs for the year 2006 and
each year thereafter.  If the calculations under both such tests produce a
reduction in Chargeable Costs, the greater of such reductions shall apply.  If
the calculation under one of such tests produces a reduction in Chargeable
Costs but the calculation under the other test does not, the calculation that
produces the reduction shall apply.  In applying the tests below, it is the
intention of Grantor and Grantee that test (i) allow as a credit toward the
400,000,000 STB of Proved Reserves that must be added to Current Reserves
during the period set forth in such test an amount equal to the excess, if
any, of the number of STB of Proved Reserves added to Current Reserves prior
to December 31, 2000 over 300,000,000 STB of Proved Reserves, while test (ii)
sets a level of only 100,000,000 STB of Proved Reserves that must be added to
Current Reserves during the period set forth in such test, but does not allow
a credit for additions of STB of Proved Reserves accrued prior to December 31,
2000.

   (i)  If, between January 1, 2001 and December 31, 2005, an additional
400,000,000 STB of Proved Reserves (that is, 400,000,000 STB of Proved
Reserves in addition to the 100,000,000 STB of Proved Reserves that are
referred to in Section 4.4(a) and the 200,000,000 STB of Proved Reserves that
are referred to in Section 4.4(b)) have not been added to Current Reserves
(before taking into account any production therefrom), then for the year 2006
and each year thereafter Chargeable Costs as set forth in the table above
shall be reduced, as of January 1 of each such year, by an amount equal to the
lesser of (A) $1.20 or (B) the product of $1.20 and a fraction, the numerator
of which shall be the difference between (1) 400,000,000 STB of Proved
Reserves and (2) the sum of (i) the actual number of STB of Proved Reserves so
added to Current Reserves from January 1, 2001 through December 31, 2010 plus
(ii) the excess, if any, of the number of STB of  Proved Reserves so added to
Current Reserves from January 1, 1988 through December 31, 2000 over
300,000,000 STB of Proved Reserves (provided that the sum of (i) and (ii)
shall not exceed 400,000,000 STB of Proved Reserves) and the denominator of
which shall be 400,000,000 STB of Proved Reserves.

   (ii) If between January 1, 2001 and December 31, 2005, an additional
100,000,000 STB of Proved Reserves (that is, 100,000,000 STB of Proved
Reserves in addition to any and all STB of Proved Reserves that are added to
Current Reserves prior to January 1, 2001) have not been added to Current
Reserves (before taking into account any production therefrom), then for the
year 2006 and each year thereafter Chargeable Costs as set forth in the table
above shall be reduced, as of January 1 of each such year, by an amount equal
to the lesser of (A) $1.20 or (B) the product of $1.20 and a fraction, the
numerator of which shall be the difference between 100,000,000 STB of Proved
Reserves and the number of STB of Proved Reserves added to Current Reserves
from January 1, 2001 through December 31, 2005 and the denominator of which
shall be 100,000,000 STB of Proved Reserves.

   Grantor shall report to Grantee the amount of Proved Reserves added in
any year, taking into account the reductions, if any, to Proved Reserves
resulting from modifications of Grantor's estimates which were made of Proved
Reserves for prior years, it being agreed that only the net amount of Proved
Reserves (that is, additions net of reductions resulting from modifications of
previous estimates of Proved Reserves) shall be utilized in determining
whether the requisite number of STB of Proved Reserves have been added
pursuant to the provisions of this Section 4.4.

   Section 4.5 Cost Adjustment Factor.  The Cost Adjustment Factor shall
mean the ratio of (1) the Consumer Price Index published for the most recently
past February, May, August or November, as the case may be, to (2) the
Consumer Price Index published most recently prior to the Effective Date,
provided, however, that (a) If for any calendar quarter the average WTI Price
was $18.00 or less, then in such event the Cost Adjustment Factor for such
quarter shall be the Cost Adjustment Factor for the immediately preceding
quarter, and (b) the Cost Adjustment Factor for any calendar quarter in which
the average WTI Price exceeds $18.00, after a calendar quarter during which
the average WTI Price is equal to or less than $18.00, and for each following
calendar quarter in which the average WTI Price is greater than $18.00, shall
be the product of (x) the Cost Adjustment Factor for the most recently past
calendar quarter in which the average WTI Price is equal to or less than
$18.00 and (y) a fraction, the  numerator of which shall be the Consumer Price
Index published for the most recently past February, May, August or November,
as the case may be, and the denominator of which shall be the Consumer Price
Index published for the most recently past February, May, August or November
during a quarter in which the average WTI Price was equal to or less than
$18.00. The Consumer Price Index shall mean the U.S. Consumer Price Index, all
items and all urban consumers, U.S. city average, 1982-84 equals 100, as first
published, without seasonal adjustment, by the Bureau of Labor Statistics,
Department at Labor, without regard to subsequent revisions or corrections by
such Bureau.

   Section 4.6 Production Taxes.  Production Taxes in existence on the
Effective Date or subsequently imposed shall be computed at defined statutory
rates.  In the case of taxes based upon wellhead or field value, WTI Price
less the product of $4.50 times the Cost Adjustment Factor shall be deemed to
be the wellhead or field value.  At the Effective Date the Production Taxes
payable with respect to the Royalty Production are the Alaska Oil and Gas
Properties Production Tax ("Alaska Production Tax") and the Alaska Oil and Gas
Conservation Tax ("Alaska Conservation Tax").  For the purposes of the Royalty
Interest, the Alaska Production Tax shall be computed without regard to the
"economic limit factor" as the greater of the "percentage of value amount"
(based on the statutory rate and the wellhead value as defined above) and the
"cents per barrel amount" as such terms are used with respect to such tax. 
Grantor hereby agrees to pay to the appropriate taxing authorities when due
all Production Taxes in respect of the Royalty Interest, except those 
Production Taxes which Grantor is contesting in good faith and which Grantor
is not required to then pay by law.  As of the Effective Date, the statutory
rate for the purpose of calculating the "percentage of value amount" is 15%
with respect to the Alaska Production Tax and four mills per Barrel of Oil
production wine respect to the Alaska Conservation Tax.

   Section 4.7 Minimum Royalty.  If, with respect to any calendar quarter
during the Minimum Royalty Period, the Average Per Barrel Royalty is less than
$8.92 per Barrel, Grantor will make an additional payment to Grantee at the
time specified in Section 3.1 equal to the sum of the product for each day of
such calendar quarter of (1) the difference between the Minimum Per Barrel
Royalty and the Average Per Barrel Royalty and (2) the Royalty Production;
provided, that the total payments under the Royalty Interest for any calendar
quarter (including any payments under this Section 4.7) shall not exceed the
aggregate value of the total production of Oil for such calendar quarter, net
of Lessor's Royalty and less  the value of any applicable payments made to the
owners of the Net Profits Royalty Interest (excluding the Lower Lower Net
Profits Royalty Interest).

   Section 4.8 Information and Reports.  Grantor shall:

   (a)  provide Grantee with such information concerning the Royalty
Interest as Grantee may need and to which Grantor has access to permit Grantee
(i) to comply with any reporting or disclosure obligations of Grantee pursuant
to applicable law and the requirements of any stock exchange in which the
securities of Grantee are listed, (ii) to prepare Alaska, federal and other
income tax returns and (iii) to prepare reports required to be forwarded by
Grantee to its security holders;

   (b)  provide Grantee and the Independent Accountants (the expenses of
such Independent Accountants to be borne by Grantee) with access, at the
office of Grantor during reasonable business hours, to inspect Grantor's books
and records, which books and records shall be true and correct in all material
respects and sufficient to enable the Independent Accountants to verify the
correctness of the amounts paid and payable to Grantee as the owner of the
Royalty Interest and to discuss with representatives of Grantor the affairs,
finances and accounts of Grantor relating to the Leases and the Subject
Interests; provided that Grantee and the Independent Accountants shall keep
the information therein confidential except for information which Grantee is
required by law to disclose;

   (c)  furnish to Grantee on or before February 28 of each year a report
containing all information of a nature, of a standard and in a form consistent
with the requirements of the Securities and Exchange Commission respecting the
inclusion of reserve and reserve valuation information in filings under the
Securities Act of 1933 and the Securities Exchange Act of 1934 and with
applicable accounting rules.  Such report shall set forth, among other things,
Grantor's estimates of future net cash flows from Proved Reserves attributable
to the Royalty Interest, the discounted present value thereof, the assumptions
utilized in arriving at the estimates contained therein, and the estimate of
the quantities of Proved Reserves (including reductions of Proved Reserves as
a result of modification of Grantor's estimates of Proved Reserves from prior
years) added to Current Reserves during the preceding year.  Current Reserves
shall not be reduced by production of Oil since December 31, 1987;

   (d)  unless such right is waived in writing by Grantee,  provide to the
Independent Petroleum Engineers (the expenses of such Independent Petroleum
Engineers to be borne by Grantee) all access and information which the
Independent Petroleum Engineers deem necessary to determine whether the
methods and procedures employed by Grantor to accumulate and evaluate the
necessary information and to estimate and document the Proved Reserves and
annual production rate forecasts and to prepare the report referred to in
Section 4.8 (c) are effective and in accordance with generally accepted
geological and engineering practices in the petroleum industry and whether
Grantor's estimate of the quantities of Proved Reserves set forth in such
report are, in the aggregate, reasonable, and if not, to determine and specify
that portion of Grantor's estimate of Proved Reserves that, in the opinion of
the Independent Petroleum Engineers, is reasonable, it being agreed that in
the event of a material disagreement with respect to the correct quantities of
Proved Reserves, the opinion of the Independent Petroleum Engineers shall
govern for all purposes of this Conveyance; in carrying out their
investigation the Independent Petroleum Engineers may review, among other
things they deem relevant, (i) Grantor's procedures for estimating and
documenting Proved Reserves, (ii) Grantor's estimates of in-place reservoir
volumes, (iii) Grantor's estimates of recovery factors and production profiles
for the various areas, pay zones, projects and recovery processes that are
included in Grantor's estimate of Proved Reserves, (iv) Grantor's production
strategy and procedures for implementing that strategy, (v) the sufficiency of
data available for making estimates of Proved Reserves and production
profiles, and (vi) pertinent provisions of the Prudhoe Bay Unit Agreement and
the Prudhoe Bay Unit Operating Agreement; provided, that, the Independent
Petroleum Engineers shall keep the information so provided confidential except
for information which is required by law to be disclosed;

   (e)  provide Grantee on a date no later than twelve calendar days prior
to each Quarterly Record Date (unless otherwise agreed by Grantee) information
as to the amount to be paid to Grantee on the next Quarterly Record Date.  

   (f)  provide to Grantee, and to Grantee's designee, a Royalty Statement
within five working days after the end of each calendar quarter which shall
consist of a computation, supported by data required to perform the
computations hereunder, of the amount to be paid to Grantee at the next
Quarterly Record Date;

   (g)  provide Grantee with such other information as Grantee may
reasonably request from time to time and to which Grantor has access.

   All costs and (expenses incurred by Grantor in providing reports and
information under this Conveyance shall be borne by Grantor.

   Section 4.9 Indemnification.  Grantor hereby agrees to indemnify and save
harmless Grantee from and against any expense (including, without limitation,
the expense of suit and attorneys' fees), claim, damage, loss or liability
incurred by Grantee as a result of or arising out of the information provided
to Grantee by Grantor pursuant to Section 4.8 being untimely provided or
incorrect or untrue or misleading in any material respect.

                          ARTICLE FIVE

                    NON-LIABILITY OF GRANTEE

   Section 5.1 Non-Expense Bearing Interest; Non-Liability of Grantee;
Indemnification. It is the express intent of Grantor and Grantee that the
Royalty Interest shall constitute (and this Conveyance shall conclusively be
construed for all purposes as creating) a non-expense bearing interest for all
purposes.  Grantor and Grantee acknowledge that, pursuant to the terms of the
Prudhoe Bay Unit Operating Agreement, if Grantor fails to pay any costs or
expenses chargeable to Grantor under the Prudhoe Bay Unit Operating Agreement
and the production of Oil is insufficient to pay such costs and expenses, then
the Royalty Interest is chargeable with a pro rate portion of such cost and
expenses and is subject to the enforcement against it of liens granted to the
unit operators of the Prudhoe Bay Unit.  However, as more fully set forth in
Section 7.2, Grantor has agreed to pay timely all costs and expenses
chargeable to it pursuant to the Prudhoe Bay Unit Operating Agreement and to
insure that no such costs and expenses will be chargeable against the Royalty
Interest.  Grantor and Grantee acknowledge that in no event shall Grantee ever
be liable or responsible in any way for any expense, claim, damage, loss,
obligation or liability incurred by Grantor or Grantee or others attributable
to the Subject Interests or to Oil produced therefrom (including, without
limitation, those incurred in connection with or attributable to the
developing, exploring, drilling, equipping, testing, operating, reworking,
maintaining, plugging or abandoning of any well or the storing, handling,
treating or marketing of the production therefrom), and Grantor hereby agrees
to indemnify and save harmless Grantee from and against any such expense
(including, without limitation, the expense of suit and attorneys' fees),
claim, damage, loss, obligation and liability, irrespective of whether same
arises pursuant to the provisions of the Prudhoe Bay Unit Operating Agreement
or otherwise.

                          ARTICLE SIX

                          UNITIZATION

   Section 6.1 Prudhoe Bay Unit.  The Subject Interests have been heretofore
unitized for the production of oil and gas in the Prudhoe Bay Unit.  The
Subject Interests are and shall be subject to the terms and provisions of the
Prudhoe Bay Unit Agreement and the Prudhoe Bay Unit Operating Agreement, the
Leases, and any other type of contract, conveyance, or Instrument, recorded or
unrecorded, relating to the Subject Interests or Grantor's interest therein in
effect at the Effective Date.

   Section 6.2 Right to Amend.  Grantor shall have the right and power to
alter, change, amend or terminate the Prudhoe Bay Unit Agreement, the Prudhoe
Bay Unit Operating Agreement, the Leases, and any other type of contract,
conveyance, or instrument, recorded or unrecorded, as heretofore or hereafter
entered into, as to all or any part of the Subject Interests, upon such terms
and provisions as Grantor shall in its sole discretion determine, but, if
Grantor exercises such right and power in breach of the Prudent Standard, it
will, and hereby agrees to, indemnify and save harmless Grantee from and
against any and all expense (including, without limitation, the expense of
suit and attorneys' fees), claim, damage, loss, obligation and liability
incurred by Grantee as a result of or arising out of Grantor's exercise of the
aforesaid right and power in breach of the Prudent Standard.  If and whenever,
through the exercise of such right and power, or pursuant to any law hereafter
enacted or any rule, regulation or order of any governmental body or official
hereafter promulgated, any of the Subject Interests are altered, changed,
amended or terminated in any manner, the Royalty Interest insofar as it
affects such Subject Interests shall also be altered, changed, amended or
terminated, and in any such event such Royalty Interest, insofar as it is
affects such Subject Interests, shall apply to and affect only the Royalty
Production which is allocated to such Subject Interests, but no such
alteration, change, amendment or termination shall affect the definition of
Royalty Production as set forth in Article One or the method of making
payments under the Royalty Interest as set forth in Article Three or the
method of computing the payments under the Royalty Interest as set forth in
Article Four.  Grantee hereby agrees that it will never challenge the right
and power of the Grantor to so alter, change, amend or terminate the Prudhoe
Bay Unit Agreement, the Prudhoe Bay Unit Operating Agreement, the Leases and
any other type of contract  conveyance or instrument, recorded or unrecorded,
as heretofore or hereafter entered into, as to all or any part of the Subject
Interests, upon such terms and provisions as Grantor shall in its sole
discretion determine, but nothing in this Section 6.2 shall be construed to
release Grantor from its indemnity obligation to Grantee as set forth in the
first sentence of this Section 6.2 and in other provisions of this Conveyance
or to deny Grantee any of the benefits to which it is entitled under this
Conveyance or at law or in equity.

                         ARTICLE SEVEN

                 OPERATION OF SUBJECT INTERESTS

   Section 7.1 Prudent Operator Standard.  Grantor agrees, to the extent it
has the legal right to do so under the Prudhoe Bay Unit Agreement, the Prudhoe
Bay Unit Operating Agreement, the Leases and applicable law affecting or
pertaining to the Subject Interests, that it will conduct and carry on the
development, exploration, production, maintenance and operation of the Subject
Interests with reasonable and prudent business judgment, in accordance with
the provisions of this Article Seven and good oil and gas field practices, as
a reasonable and prudent operator, and without regard to the existence of the
Royalty Interest or any other royalty, overriding royalty, or other interest
created subsequent to the Effective Date (the "Prudent Standard").  However,
nothing contained in this Section 7.1 shall be deemed to prevent or restrict
Grantor from electing not to participate in any operation which is to be
conducted under the terms of either the Prudhoe Bay Unit Agreement or the
Prudhoe Bay Unit Operating Agreement if such election is made by Grantor in
accordance with the Prudent Standard.  Grantor shall not be obligated to
continue to produce Oil from the Subject Interests in the Prudhoe Bay Unit or
to maintain such production at any particular level so long as Grantor acts in
accordance with Prudent Standard.  Notwithstanding anything elsewhere herein
to the contrary, Grantor shall never be liable to Grantee for the manner in
which Grantor performs its duties hereunder as long as Grantor has acted in
accordance with the Prudent Standard.  Grantee shall have no right to operate
or direct operations of the Subject Interests.

   Section 7.2 Assurances. (1) Grantor agrees, to the extent it has the
legal right to do so under the terms of the Prudhoe Bay Unit Agreement, the
Prudhoe Bay Unit Operating Agreement, the Leases and applicable law affecting
or pertaining to the Subject Interests, that it will perform all material
obligations to be performed by it (including without limitations making timely
payment of all costs and expenses  chargeable to it pursuant to any applicable
agreement to insure that the Royalty Interest is not charged with any portion
of any such costs or expenses and that no lien or security Interest is
enforced against the Royalty Interest by virtue of any matter arising by
through or under Grantor) under all material contracts and agreements
applicable to the Subject Interests and the production and transportation to
market of Oil (including, without limitation, the Prudhoe Bay Unit Agreement
and the Prudhoe Bay Unit Operating Agreement) and will use its best efforts
(by taking such action as is available to it by contract, at law, or in
equity) to enforce the performance under such contracts and agreements of the
other parties thereto.

   (ii) The provisions set forth in this Conveyance that require Grantor to
perform certain duties or take certain actions (but subject to the express and
implied limitations in this Conveyance) that can only be performed or taken by
the operator of the Prudhoe Bay Unit, acting under the direction and
supervision of the working interest owners of the Prudhoe Bay Unit, or the
operators of facilities or pipelines separate from the Prudhoe Bay Unit, shall
be construed to require Grantor to use its best efforts (by taking such action
as is available to it by contract (including, without limitation, exercising
its right to vote and to initiate proposals), at law or in equity) to cause
the operator to perform the duty or to take the action in question.  Without
limitation of the generality of the foregoing, if the operator elects,
pursuant to the applicable operating agreement, to become a nonconsenting
party with respect to such duty or action, and if Grantor may cause such duty
or action to be performed or taken by becoming a consenting party under the
applicable operating agreement, then Grantor shall so elect to become a
consenting party unless a reasonable and prudent operator, acting in
accordance with good oil and gas field practices and without regard to the
existence of the Royalty Interest or any other royalty, overriding royalty or
other interest created subsequent to the Effective Date, would refuse to
undertake the performance of the duty or the taking of the action in question.

   Section 7.3 Abandonment of Properties.  Nothing herein contained shall
obligate Grantor to continue to operate any well or maintain in force or
attempt to maintain in force any of the Subject Interests when, in Grantor's
opinion, formed in accordance with the Prudent Standard, such well or Subject
Interest ceases to produce or is not capable of producing oil or gas in paying
quantities.  The expiration of a Subject Interest in accordance with the terms
and conditions applicable thereto shall not be considered to be a voluntary 
surrender or abandonment thereof.

   Section 7.4 Non-Operating Interest In Minerals.  It is the express intent
of Grantor and Grantee that the Royalty Interest shall constitute (and this
Conveyance shall conclusively be construed for all purposes as creating) a
non-operating interest in minerals for all purposes.  Without limitation of
the generality of the immediately preceding sentence, Grantor and Grantee
acknowledge that Grantee has no right or power to participate in the selection
of a drilling contractor, to propose the drilling of a well, to determine the
timing or sequence of drilling operations, to commence or shut down
production, to take over operations or to share in any operating decision
whatsoever (including, without limitation, the alteration, change, amendment
of termination of the Prudhoe Bay Unit Agreement, the Prudhoe Bay Unit
Operating Agreement, the Leases or any other type of contract, conveyance, or
instrument, recorded or unrecorded, as heretofore or hereafter entered into,
as to all or any part of the Subject Interests hereunder).  Grantor and
Grantee hereby expressly negate any intent to create (and this Conveyance
shall never be construed as creating) a mining or other partnership or joint
venture.

                         ARTICLE EIGHT

                     GOVERNMENT REGULATION

   Section 8.1 Government Regulations.  All obligations of Grantor hereunder
shall be subject to all applicable laws, regulations and rules of the State of
Alaska and the United States of America and all other governmental agencies or
authorities having jurisdiction in the matter (except those being contested in
good faith).  Grantor shall be entitled to use its reasonable discretion in
making filings, for itself and on behalf of Grantee, with any governmental
body, agency, board or commission having jurisdiction, affecting the Subject
Interests or the Royalty Interest, provided that any such filings shall be
limited to notice required in connection with the grant or transfer of the
Royalty Interest.

   Section 8.2 Government Approval.  This Conveyance shall not be effective
until approved by the Commissioner of the Department of Natural Resources,
State of Alaska, or his designee.

                          ARTICLE NINE

                          ASSIGNMENTS

   Section 9.1 Assignment by Grantor.  Grantor shall have the right to
assign, sell, transfer, convey, mortgage or pledge the Subject Interests, or
any part thereof, provided that same is expressly made subject to the Royalty
Interest and the terms and provisions of this Conveyance and that a certified
copy of the recorded instrument accomplishing same is promptly furnished to
Grantee by Grantor.  From and after the effective date of any such assignment,
sale, transfer or Conveyance by Grantor, the grantee thereunder shall succeed
to all the requirements upon and responsibilities of Grantor hereunder as to
the interests so acquired by such grantee, and, from and after said effective
date, Grantor shall be relieved of such requirements and responsibilities,
excepting only for those accrued or due for performance prior to such
effective date and except as otherwise provided in Section 9.2. The kind of
notice provided herein shall be exclusive, and no other kind, whether actual
or constructive, shall be binding on Grantee.

   Section 9.2 Effect of Assignment by Grantor.  Notwithstanding any
provision of this Conveyance to the contrary, no assignment, sale, transfer,
conveyance, mortgage or pledge of the Subject Interests, or any part thereof,
shall adversely affect any of Grantee's rights hereunder, including, without
limitation, the amount, computation or method of payment of the Royalty
Interest, it being the intent of Grantor and Grantee that for the purpose of
determining the Royalty Interest payable to Grantee no disposition will be
deemed to have been effected during the term of this Conveyance.  Should
Grantor dispose of its interest in the Subject Interests as to some of the
Subject Interests, or as to some part thereof, then, effective as of the date
of such disposition, BP Exploration (Alaska) Inc. shall automatically be
designated by all owners of the Subject Interests as their agent, throughout
the term of this Conveyance, (i) to make all designations that Grantor is
entitled to make pursuant to Section 4.3, (ii) to obtain all information and
take such other steps as may be necessary to permit the Independent Petroleum
Engineers and the Independent Accountants and Grantor to perform their
respective obligations and duties under this Conveyance (including, without
limitation, the calculations to be made pursuant to Article Three and Article
Four) and (iii) to make all payments and to deliver and receive all
communications on behalf of Grantor, it being agreed that during such time, if
any, that the Subject Interests are owned by more than one Person, Grantee
shall  never be obligated without its consent to receive payments from or to
deliver or receive communications under this Conveyance from or to any Grantor
other than BP Exploration (Alaska) Inc.; provided, however, that BP
Exploration (Alaska) Inc. shall be released from its obligations under this
Conveyance upon the sale or transfer by it of all or substantially all of the
Subject Interests, if the transferee is of Equivalent Financial Standing and
unconditionally agrees to assume and be bound by all of BP Exploration
(Alaska) Inc.'s obligations under this Conveyance in a writing in form and
substance reasonably satisfactory to Grantee.

   Section 9.3 Assignment by Grantee.  Grantee has the right to assign the
Royalty Interest in whole or in part.  No such assignment will affect the
method of computing the Royalty Interest, and if more than one Person becomes
entitled to participate in the Royalty Interest, Grantor may withhold from
such other Person payments to which such Person would otherwise be entitled
hereunder and the furnishing of any data or information which Grantor is
required by the terms hereof to furnish Grantee until Grantor is furnished a
recordable instrument executed by or binding upon all Persons interested in
the Royalty Interest designating one Person who is to receive such payments,
data and information.

   Section 9.4 Change In Ownership.  No change of ownership or right to
receive payment of the Royalty Interest, or of any part thereof, however
accomplished, shall be binding upon Grantor until notice thereof shall have
been furnished by the Person claiming the benefit thereof, and then only with
respect to payments thereafter made.  Notice of sale or assignment shall
consist of a certified copy of the recorded instrument accomplishing the same;
notice of change of ownership or right to receive payment accomplished in any
other manner (for example by reason of incapacity, death or dissolution) shall
consist of certified copies of such documents and complete proceedings as are
legally binding and conclusive of the rights of all parties.  Until such
notice shall have been furnished to Grantor as above provided, the payment or
tender of all sums payable on the Royalty Interest may be made in the manner
provided herein precisely as if no such change in interest or ownership or
right to receive payment had occurred.  The kind of notice herein provided
shall be exclusive, and no other kind, whether actual or constructive, shall
be binding on Grantor.

   Section 9.5 Rights of Mortgagee or Trustee.  If Grantee shall at any time
execute a mortgage or deed of trust covering all or part of the Royalty
Interest, subject to the notice provisions of Section 9.4, the mortgagee(s) or
trustee(s)  therein named or the holder of any obligation secured thereby
shall be entitled, to the extent such mortgage or deed of trust so provides,
to exercise all the rights, remedies, powers and privileges conferred upon
Grantee by the terms of this Conveyance, but the provisions of this Section
9.5 shall in no way be deemed or construed to impose upon Grantor any
obligation or liability undertaken by Grantee under such mortgage or deed of
trust or under the obligation secured thereby.

                          ARTICLE TEN

                         MISCELLANEOUS

   Section 10.1 Proportionate Reduction.  In the event of failure or
deficiency in title of the State of Alaska to any of the Lands which affects
any of the Subject Interests, or any modification of the Subject Interests as
provided in Article Six, the portion of the Royalty Production from such
affected or modified Subject Interests out of which the Royalty Interest
attributable to such Subject Interests shall be payable shall be reduced in
the same proportion that such Subject Interests are reduced, but such failure
or deficiency in title shall not affect the definition of Royalty Production
as set forth in Article One or the method of paying the Royalty Interest as
set forth in Article Three or the method of computing the payments to be made
under the Royalty Interest as act forth in Article Four.

   Section 10.2 Term.  Subject to the limitations stated herein, this
Conveyance shall remain in force so long as any of the Subject Interests are
in effect, provided, however, that all warranties and indemnities set forth in
this Conveyance shall survive for the maximum period permitted by law.

   Section 10.3  Further Assurances.  Should any additional instrument of
assignment or conveyance be required to describe more specifically any
interests subject hereto or to vest in any Person to whom Grantee assigns the
Royalty Interest in whole or in part the benefit of all covenants,
representations, warranties and indemnities made by Grantor to or for the
benefit of Grantee pursuant to this Conveyance, Grantor agrees to execute and
deliver the same.  Also, if any other or additional instruments are required
in connection with the transfer of interests in the Leases to comply with
applicable law, regulations, the Prudhoe Bay Unit Agreement, the Prudhoe Bay
Unit Operating Agreement or any other applicable agreements, Grantor will
execute and deliver the same.

   Section 10.4  Notices.  Any notice, request, demand, report, statement or
other instrument which may be required or permitted to be given to any party
hereto or other Person succeeding to any interest of a party hereto shall be
deemed sufficiently given if in writing and delivered to such party or Person
or to an officer of such party or Person or deposited in the United States
mail in a sealed envelope, first class mail, with postage prepaid, addressed
to such party or Person at its or his address stated in this Conveyance, or at
such other address as the party or Person to be addressed shall have
designated by written notice to each such party or Person.  Each party's
proper address shall be deemed to be that set forth herein below until such
party gives to the other party, in the manner above prescribed, notice of a
new address, after which such new address shall be deemed the proper address
until changed in like manner.  Notice shall be deemed given when actually
received by the party or Person to which such notice was intended.

Agreement.  Grantor further covenants that if the existence of the Net Profits
Royalty Interest or the making of any payments under the Net Profits Royalty
Interest results in a decrease in any payment to Grantee under the Royalty
Interest, Grantor shall and hereby agrees to pay Grantee, in addition to and
independent of  payments required to be made to Grantee under the Royalty
Interest, the amount of any such decrease, together with interest thereon in
an amount equal to the product of (i) the amount of such decrease, (ii) the
Interest Rate, and (iii) a fraction, the numerator of which is the number of
days from the date of such decrease until the date of payment to Grantee of
the amount owing pursuant to this Section 10.5 and the denominator of which is
360 days, together with such other damages (but not including interest) to
which Grantee may be entitled under this Conveyance, or at law or in equity,
it being the express intent of Grantor and Grantee that Grantee is not to be
prejudiced in any way by the existence of or the making of any payments under
the Net Profits Royalty Interest.

   Section 10.6 Other Covenants.  Grantor hereby covenants and warrants that
it is a corporation duly organized, validly existing, and in good standing
under the laws of the State of Delaware, is qualified to transact business and
is in good standing in the State of Alaska and is qualified with the Alaska
Department of Natural Resources to hold interests in state oil and gas leases;
that it has the legal right and authority to bargain, grant, sell, convey,
transfer, assign, set over and deliver the Royalty Interest to Grantee and
that it has the legal right and authority to execute, deliver and perform this
Conveyance; that the execution, delivery and performance of this Conveyance by

than the filings which are required under the terms of the Leases and the
terms of applicable statutes of the State of Alaska and the administrative
regulations of the Alaska Department of Natural Resources, which filings will
be promptly made upon execution of this Conveyance; and, (iii) will not
violate or conflict with any law, statute, regulation, agreement, judgment,
injunction, order, decree or other instrument to which Grantor is subject or
is party or by which Grantor or the Leases or the Subject Interests are bound
and that this Conveyance is a valid and binding agreement of Grantor,
enforceable against Grantor in accordance with its terms.  Grantor hereby
binds itself and its successors and assigns to forever defend the title to the
Royalty Interest unto Grantee and its successors and assigns against every
Person claiming the same or any part thereof by, through or under Grantor, but
not otherwise.  This Conveyance is made with full substitution and subrogation
of Grantee in and to all covenants, representations and warranties by others

the covenants contained in this Conveyance run with and burden the Lands and
the Subject Interests to the maximum extent possible under applicable law.

   Section 10.11 Waiver; Estoppel.  The failure of Grantor or Grantee to
insist upon strict performance of any provision of this Conveyance shall not
constitute a waiver of or estoppel against asserting the right to require such
performance in the future, nor shall a waiver or estoppel in any one instance
constitute a waiver or estoppel with respect to a later breach of a similar
nature or otherwise.

   Section 10.12 Right to Information.  The Standard Oil Company shall
remain entitled throughout the term of this Conveyance to receive from Grantor
a copy of all information that is furnished to Grantee by Grantor,

Interest in whole to any other Person.
